[0001] The present invention relates to a method and a device for marking thin glass along cutting lines, for the purpose of marking and separation by rupture, as well as a glass marked thin, prepared by a process of this type. Here, the term "thin glass" refers to flat glass having a wall thickness of between 1.2 mm and 3 μm, which may be produced as a glass ribbon or glass film and may be wound. However, the labeled thin glass must also be produced in platelet format as a premarketed plate. After breaking along the marking, small plates of thin glass must be obtained, which are then treated as a component in the field of electrical engineering, electronics or in electric batteries. Thin glasses are used in many technological fields, for example in display devices, in optoelectronic component windows, in encapsulation components and in electrical insulation layers. These applications require small plates of thin glass. However, the thin glass is mainly produced in the form of glass ribbon or glass film, and for some time, thicknesses of less than 350 μm are required. When such a thin glass ribbon or thin glass film is to be processed to obtain smaller thin glass plates, handling difficulties are encountered. The thin-glass processing industry generally does not wish to receive small plates of diced thin glass for further processing, but thin glass rolled into rolls, which is prepared to be separated into small thin glass plates. However, in the case of premarketed thin glass, this is a problem. Indeed, when the thin glass is curved at the time of winding, there is a risk of premature failure along the cutting line. A single break may already interfere with the subsequent treatment process that will have to be interrupted during unwinding of the thin glass due to the break location. The object of the invention is to prepare premarketed thin glass in a manner which allows for a subsequent reliable treatment of premarketed thin glass. To avoid the risk of premature failure along the cutting line, prepared markings must have a predefined quality. Markings shall be as uniform as possible, that is, the marking tool shall be accurately directed along the intended cutting lines and with a marking contact pressure force as constant as possible. In a thickness range between 1.2 mm and 350 μm, this is possible because of the relatively large marking contact pressure force to be set for marking. However, when ultrathin glass (UTG) is to be marked and the marking contact pressure applied to the glass must adopt small values (not exceeding 2 N), there is a growing risk that the tool marking temporarily slide on the surface of the glass to be marked, which is known as slip phenomenon and has already been observed with glass cutting heads of the prior art. According to a first aspect of the invention, there is provided a thin glass marking device, which makes it possible to maintain the constant marking contact pressure force in a sufficiently precise manner along the expected cutting lines, avoiding in a large extent the friction forces. For this purpose, the marking tool is pressed onto the thin glass by means of a parallel beam which comprises two or more spring blades and is driven along the intended cutting line by a machine tool digital. The marking contact pressure of the marking tool is controlled in a controlled manner using a measuring device which advantageously determines the marking contact pressure force on the basis of the deflection of the parallel beam from its position. neutral.
[0002] In the scope of the present invention, the term "cutting tool" is a synonym for "marking tool". In the same way, the terms "cutting head" and "marking head" are used as synonyms. By cutting a glass, for example a thin glass, is meant marking and subsequent separation. Therefore, the marking is part of a cutting process. In the context of the present invention, the term "glass marking" means any weakening of the surface area, for example by making a continuous or discontinuous cut.
[0003] To avoid the phenomenon of jerky sliding in the marking tool holder at the marking head, the marking element of the marking tool is mounted in a marking tool housing, via a journal, in aerostatic bearings with a damping fastening element in the axial direction of the journal and with a radial guide for a pivoting movement of the element of the marking tool. The marking tool can be placed with a substantially constant force on the thin glass to be marked and can be pulled along the intended cutting line. When the intended cutting line comprises bends, the aerostatic bearings offer a reduced friction fit, without the phenomenon of jerky slip when using ball bearings generally used until now to support the trunnion of the tool. cutting with cutting heads of the prior art. In addition, the proposed marking head has a lower moment of inertia, compared to conventional cutting heads of the prior art, and can be lightweight design. A second aspect of the invention relates to process control and processing during marking of thin glass. When a predefined marking depth must be kept constant, it is useful to determine a quantity derived from the marking depth. The marking depth is related to the degree of deflection of the parallel beam during the traction of the marking tool and can be calculated from the measured deviation. If marking resistance irregularities appear in the thin glass, the disturbance can be maintained at a low level by means of a control loop and can be maintained within a tolerance range of the marking depth. On the other hand, a control means in the marking device is intended to adjust variable marking depths, for example to compensate for the differences in marking and breaking behavior or in the vicinity of a peripheral edge of the thin glass, compared to a more central area of thin glass. The same goes for thin glass of varying thicknesses with respect to the two longitudinal and transverse dimensions thereof. A third aspect of the invention relates to the manufacture of premarketed thin glass, as a semi-finished product for small new thin glass plates for which there are useful applications in various fields of consumer electronics. Such small thin glass plates, which are obtained after marking and separation by rupture, are suitable as protective glasses for display devices, touch panels, photovoltaic cells, semiconductor modules or LED light sources. But small thin glass plates can also be used as capacitor element, thin-film batteries, flexible printed circuit boards, flexible OLEDs, flexible photovoltaic modules or electronic paper. The type of thin glass can be chosen specifically according to the intended field of application, in order to meet the requirements concerning chemical resistance, resistance to thermal shock, heat resistance, gas tightness, high electrical insulation , a suitable expansion coefficient, flexibility, high optical quality and light transmission, with a high surface quality. Thin glass has a flame-polished surface on both sides and therefore has a very low roughness. Thin glass having a requirement profile as mentioned above has a Knoop HK hardness in a range from 350 to 650. For the purposes of the invention, a Knoop hardness range between 550 and 650 is preferable, but Knoop hardness may also have values greater than 650. In case of higher Knoop hardness, lower marking depths will be sufficient for breaking along the cutting line, thus avoiding the risk of premature failure on the cutting edge. along the cutting line, in the case of a coiled thin glass material. In practice, the marking depth can be between 1/20 and 4/5, preferably between 1/20 and 1/5 of the thickness of the thin glass, with cracks extending in the glass material thin depending on the marking depth.
[0004] To successfully achieve the marking method presented here, the composition of the thin glass also plays an important role. The following types of glass have been found particularly suitable: lithium aluminosilicate glass, soda-lime glass, borosilicate glass, aluminosilicate glass of alkali metal and aluminosilicate glass. The invention will now be described with the aid of an exemplary embodiment of a device with reference to the drawing. The single figure schematically shows a longitudinal sectional view of a marking head of a numerically controlled machine tool.
[0005] The main elements of the marking head of the numerically controlled machine tool include a marking tool 1, a marking drive mechanism 2, a driven feed carriage 3, a parallel beam 4 and a measuring device 5. The marking head, together with the marking tool 1, can be moved on a cutting table 6 of the machine tool, in horizontal directions x and y. The driven feed carriage 3 sets the marking tool 1 in the z direction and can comprise a feed control, not shown, and a precision control 8. The feed control is used to set the feed. marking tool 1 on the part, that is to say the thin glass 9, preferably without exerting a force on the thin glass 9. The precision control 8 provides the force of contact pressure of marking of the tool 9. To carry out this operation in a controlled manner, there is provided a controller of real values / target values 7.
[0006] The marking tool 1 comprises a marking tool housing 10 with aerostatic bearings 11 and 12 housed therein, as well as a marking tool holder 13 and a marking element 14. In general, without To be limited to the example illustrated here, the bearings can be configured as magnetic, aerostatic and / or mechanical bearings, and appropriate measures should be provided to reduce the frictional forces. The marking element may be in the form of a sintered diamond cutting wheel, but hard metal cutting wheels and cutting diamonds may also be used. The marking tool holder 13 comprises a journal 15, mounted in radial bearings 12, and a piston 16 supported by an axial bearing 11. The aerostatic bearings 11, 12 are supplied with compressed air via air ducts compressed to obtain the guidance and the necessary degrees of freedom of movement, using air cushions generated in compressed air chambers. The marking element 14 is attached to the marking tool holder 13, its axis being offset with respect to the axis of the journal 15, so that the marking element 14 can be pulled on the thin glass 9 along the cutting line provided, being located behind the axis of the pin 15, seen in the direction of travel. The marking tool casing 10 is fixed to the driven feed carriage 3 via the parallel beam 4 in order to follow the movement of the latter in the z direction, until marking 14 is placed on the thin glass 9. The parallel beam 4 is a parallelogram comprising two or more spring blades 40 and clamping elements 41 and 42 which clamp the ends of the leaf springs 40. The clamping element 41 is attached to the marking tool housing 10, and the clamping member 42 is attached to the feed carriage 3.
[0007] To avoid the generation of resonance vibrations of the system of the marking tool 1 and the parallel beam 4 during the traction of the marking element 14 on the surface of the thin glass 9, it is advantageous to choose a plurality of blades of spring 40 having different stiffness characteristics for the configuration of the parallel beam 4. If resonant oscillations occur for a leaf spring, they are attenuated and removed by the other leaf spring. Besides the variation of the number of spring blades, it is also possible, for the configuration of the parallel beam, to modify the thickness, the width, the length and the material thereof. Suitable materials include metal, plastics, carbon, Kevlar, graphene and others. To carry out the marking, the marking tool 1, with the marking element 14, is placed on the thin glass 9, if possible without contact pressure. For this purpose, the "substitution contact input" can be used, by providing a pair of parallel stops, a first one having an abutment surface which is aligned with the horizontal plane of the lower edge of the marking element, and the second has an abutment surface aligned with the horizontal plane of the upper surface of the thin glass to be marked. Then, the pair of parallel stops is deactivated, and in a second step the thin glass 9 is subjected to the marking contact pressure force. This is achieved using the precision control 8. Starting from the contacting position of the marking tool 1, the driven feed carriage 3 performs a downward movement in the z direction, caused by the 8, and the marking element 14 penetrates the thin glass 9, the spring blades 40 are biased until the required marking contact pressure force is reached, without introducing a friction force in the force production system and therefore a jerky slip phenomenon when applying the contact force of thin-glass marking contact. Even if there are slight variations in the surface topography of the thin glass, the cutting table, or the drive of the machine tool in x-y directions, this will not happen. Even when the drive is performed with a variable marking contact pressure force, there will be no influence of a frictional force on the adjustment of the respective marking contact pressure force.
[0008] A linear piezoelectric control is suitable as precision control 8. As a sensor of the measuring device 5, a strain gauge can be used on one of the leaf springs 40 to determine the deflection of the parallel beam 4 in the z direction. after the contacting of the marking tool 1 with the thin glass 9. Since the elastic constants of the leaf springs 40 of the parallel beam 4 are known, the vertical component of the marking force can be measured and displayed on 4. As mentioned above, the vertical component of the marking force can be set to the desired values, without friction force component, and can be maintained using the actual values / values controller. 7. As a result, a control loop is provided for the process control and comprises the measuring device 5, the value controller. they / target values 7 and the precision control 8 of the advance carriage 3. The real values / target values controller 7 comprises a target value memory, intended to enter and store target values of the vertical marking force component. along the expected cutting lines, and a comparison circuit for detecting discrepancies between the actually measured values and the stored target values of the vertical marking force component. In case of differences, that is to say of so-called "error" signal, the precision control 8 of the feed carriage 3 is driven in the direction of reduction of the error signal. With this measurement, the magnitude of the required marking force can be guaranteed at any time. If the target memory is adapted to store variable target values, it is possible to program variable marking force characteristics. This is useful for optimizing the process. In order for the marking tool 1 to move along the chosen cutting lines on the thin glass 9, there is provided the marking drive mechanism 2, on which the driven feed carriage 3 is mounted, so as to in conjunction with the marking tool 1, follow the movements of the marking drive mechanism 2. If a certain undulation of the surface of the thin lens is encountered, the influence thereof on the marking depth can be compensated by the regulation loop. On the other hand, by using the aerostatic axial bearing 11 with the axial air cushion, movements in the z direction are damped, which reduces the rate of change of the marking force component following the appearance of the ripple on the surface of thin glass. Furthermore, using the aerostatic radial bearing 12 (instead of ball bearings for mounting the journal 15) and using the parallel beam 4 (instead of screw drives to solicit the cutting tool relative to the piece), a substantial mass of inertia is avoided on the marking tool, which has an influence on the accuracy of maintaining the desired magnitude of the vertical marking force component, when it is adjusted. This is particularly critical because the objective is to premark including ultrathin glass (UTG) with a thickness of less than 350 gm, so that it can be stored under storage conditions without undesired premature failure along of the cut line, which is a very delicate operation in terms of maintaining the appropriate marking depth. The device and method according to the invention make it possible to adjust extremely small quantities of the vertical marking force component, so that even extremely thin glasses can be premarketed for subsequent processing. This is particularly due to the fact that it is possible to obtain particularly good resistances on the edges. The operation of the marking head of the machine tool with the elastic parallel beam is also advantageous if the thin glass marking device is configured without measuring and control means and without aerostatic mounting of the marking element. The operation of the marking head according to the invention makes it possible to mark thin glass in particular with a very uniform application of the force of 2 N and less; when using cutting wheels, preferably with less than 1.2 N, and when using diamond tips, with less than 0.5 N, without causing the phenomenon known as "slip jerky".
[0009] With the marking head according to the invention, the inventors have succeeded in marking thin glass with a very constant marking force. The uniformity is within a range of + 0.05 N, preferably + 0.03 N of the nominal contact force. This gives edge quality substantially free of cracks, associated with high edge strength. Contrary to this, with a marking head of the prior art, marking is possible only with a non-uniform marking force and with force peaks, amplified in particular by the phenomenon of jerky sliding which results and which, compared to the invention, leads to an edge quality having a large number of cracks and therefore a low edge strength. In another embodiment of the invention, the labeling is carried out under a controlled atmosphere, especially in an environment specifically conditioned by a fluid phase. The fluid phase is preferably composed of alcohols, especially absolute alcohols, and particularly advantageously of absolute ethanol. Other fluids include deionized water, Lockstedter (45% vegetable liquor) and liquids which are disclosed in European Patent EP 1 726 635 Bi. Here, the marking tool is surrounded by the fluid phase, at least partially and preferably completely. In the context of the present application, thin glass refers to plate-shaped or ribbon-shaped or film-like glass with a wall thickness of <1.2 mm or <1.0 mm or <0.8 mm or <0.6 mm or <350 ktm or <250 itm or <100 ktm or <50 pu, but with a minimum thickness of 3 m or 10 m or 15 m. This thin glass is often stored as rolls. However, if premarketed thin glass is to be stored in a coiled form without premature failure, special measures will be required to prevent premature failure. The winding should never be made in a way that the marking is under tension or even appears on the outer circumference of the coiled roll. This means that the marking openings must be turned towards the core of the winding. On the other hand, the lateral edges of the thin glass, which are curved to form the roll, should not be weakened, because experience has shown that the break begins on these side edges, even in thin glass which does not. was not premarque. With the invention, it is possible to ensure that the marking does not extend to the edges of the thin glass. The marking in the central zone of the thin glass is sufficient to subsequently perform the break along the cutting line. To determine the correct marking depth in order to premark thin glass, the procedure is experimental. Markings are produced with a depth such that the desired small glass plates are obtained during the final treatment of the thin glass and with the marking contact pressure forces applied thereto. Next, it is determined whether premarketed thin glass can be stored without premature failure along the cutting line, for example in the form of rolls. If this is not the case, the geometry of the markings must be modified in terms of depth of marking. Accordingly, the requirements for final break along the cutting line must be predetermined to be applied during the final production of the small glass plates. The break along the cutting line will succeed even more easily as the thin glass is brittle. Knoop HK hardness can be considered as a measure of the friability of thin glass. Therefore, it is advantageous that the thin glass has high Knoop hardness values if it is to be made into small thin glass plates. It has been found that marking depths in a range between 1/20 and 4/5, preferably between 1/20 and 1/5 of the material thickness advantageously contribute to the production of premarketable thin glass that can be stored.
[0010] Glass compositions are indicated below, which are suitable for thin glass having a Knoop HK hardness in the range of 550 to 650 and above, as far as possible, and in particular for ultrathin UTG glass of <350 μm. which is to be treated according to the process of the invention.
