Description

Method and apparatus for separating bonded glass plates

The present invention relates to a method and apparatus for separating a laminated glass plate consisting of two glass plates bonded at least in part by an adhesive layer by laser beams from outside applied to the two glass plates, respectively.

A liquid crystal display (LCD) consisting of two glass plates (laminated glass plates) bonded to each other, which are today very usefully manufactured in a plurality of laminated glass plates having uniform dimensions and then separated by separating the laminated glass plates. ) And other electrical displays in particular, there is an increasing need for high edge quality in the separation of laminated glass plates and in particle-free manufacture of laminated glass plates.

In separating the corresponding laminated glass plates into individual displays, the two glass plates are each separated along a predetermined dividing line between the two adhesive bands (adhesive lines) which respectively partition the display. In this case, the separation line may pass through the adhesive line, for example, adjacent to the filling joint pipe. In order to expose the bonding strip located between the glass plates, only one glass plate may be separated from the two glass plates. The glass plates have a thickness of about 0.2 mm to 1 mm and are bonded at intervals of a micrometer area, the gap being determined according to the thickness of the bond line.

A method of separating a laminated glass plate by using a laser has been disclosed, wherein the upper glass plate of the horizontally seated laminated glass plate is separated by a laser beam applied from the top, and the lower glass plate is separated by a laser beam applied from the bottom. .

An apparatus for carrying out this method is disclosed in US Pat. No. 6,576,870 B2. The apparatus shown in FIG. 2 described herein includes a support member 34, a worktable 36 adjacent to the support member, an upper laser head 38a above the worktable 36, and the worktable. (36) The lower laser head 38b of the lower part is provided. The work table 36 has a linear opening 37.

In order to separate the laminated glass plate 32, the laminated glass plate 32 is arrange | positioned at the work bench 36 so that the separation line provided so that two glass plates may penetrate along the linear opening 37 may be carried out. The first laser beam from the upper laser head 38a is directed along the provided separation line to the upper glass plate, i.e. the upper, outer surface of the laminated glass plate 32, from the lower laser head 38b. The second laser beam of light passes through the linear opening 37 (work gap) to the lower glass plate, ie the lower outer surface of the laminated glass plate 32. This can be done simultaneously or sequentially.

It is separated with gaps like the adhesive layer of the laminated glass plate open.

Indeed, a workbench for separating a laminated glass plate composed of a fixing part and a delivery part moving horizontally with respect to the fixing part on both sides using a laser is known. The fixing portion and the delivery portion each have a seating surface in the same plane.

The laminated glass plate to be treated is basically rectangular with two side edges, a front edge and a distal edge and is seated above the fixture by the front edge towards the delivery, so that one side edge of the two side edges is Side of the guide rail is installed. In order to move the laminated glass plate towards the workbench, the laminated glass plate is fixed to a sledge gripper adjacent to its distal edge which is at least two, indirectly linearly driven. The sledge gripper is moved to a groove formed in the mounting surface and the mounting surface in parallel with the guide rail, in order to move the laminated glass plate to the work table in steps by a band width to separate the glass plates, respectively.

A plurality of grooves are provided on the width of the fixing part so that the work table can be elastically installed with respect to various widths of the laminated glass plate, and the sledge gripper can be moved to the groove. In line with the groove in the fixing part, a groove of the same width is provided in the transmitting part so that the last cut edge section can also be moved over the transmitting part past the fixing part. A suction surface exists between the grooves, and the laminated glass plate on the suction surface may be attached onto the work table during the cutting process.

The disclosed work bench has two major disadvantages:

1. In cutting from the top, the laminated glass is seated on a closed workbench, ie the delivery part is in close contact with the fixing part. The seating surface for the laminated glass is formed by the surface contours of the transmission part and the fixing part, the contours being determined by the suction surface and the grooves. When a laser beam is guided along the desired separation line from the top to the upper outer surface of the laminated glass plate, a non-homogeneous thermal tension causes the separation line to be released due to the inhomogeneous heat from the lower outer surface of the laminated glass plate. Therefore occurs.

Heat dissipation in the upper part of the groove is performed only by heat radiation while thermal conduction is applied in a flat seating area above the suction surface irrespective of the material of the suction surface.

Different thermal conditions along the dividing line negatively affect edge quality.

2. On cutting from the bottom, the delivery part rests on the fixing part until it reaches the working gap. The width of the working gap is determined by the required movement clearance of the tool head which directs the laser beam through the working gap and from the bottom to the laminated glass plate. Unlike cutting from the top, the thermal conditions along the separation line are the same, ie heat is evenly discharged by heat radiation from the top outside of the laminated glass plate. However, when the edge is cut, the edge must be wide enough to be seated on the working table, so that the edge falls out of control and falls when detached. Thus, a minimum width of the edge is formed at the front edge and the distal edge, which results in a larger amount of material falling than expected.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method and apparatus suitable for cutting a laminated glass plate into a band and in particular a narrow edge band with high edge quality using a laser.

The problem is solved by the method according to claim 1 and the device according to claim 4.

Preferred embodiments are described in the dependent claims.

According to the device according to the invention, in particular, it is used not only as an abutment when laying a mechanical start crack to apply a mechanical flexural force to the separation line, but also as a heat sink. A retractable presser, which can also be used as a furnace, and a continuous flat seating surface for the laminated glass plate on the one hand for separation from the top to prevent the edge band from tearing by itself and on the other hand There is only a rotatable flap which is mechanically supported upon removal from the bottom of the narrow edge band.

According to the method according to the invention, in particular, the order of separation is first in the order of the lower glass plate, then the adhesive layer, and finally the upper glass plate, and the separation of the adhesive layer is carried out by applying mechanical bending stress from the top.

According to the separation method and apparatus of the laminated glass plate according to the present invention, the laminated glass plate can be cut into a band and in particular a narrow edge band with high edge quality using a laser.

Hereinafter, the present invention will be described in more detail by examples with reference to the drawings.

Like the device known from the prior art, the device according to the invention shown in FIG. 1 has a fixing part 1 and a delivery part 2 which is horizontally transferable towards the fixing part 1. A worktable having a worktable, an upper tool head 3 capable of running above the worktable, and a lower toolhead 4 running below the worktable over the width of the worktable. The tool heads 3, 4 each have a laser ray outlet and a coolant jet outlet, each beam / jet passing through the outlets in a manner well known to those skilled in the art. 6) Head up.

The fixing part 1 and the transmission part 2 each include seating surfaces on which a laminated glass plate 6 to be separated is mounted, in a common horizontal plane. The laminated glass plate 6 generally forms a rectangle with two side edges, one front edge 7 and a terminal edge.

In the figure, the laminated glass plate 6 is placed in a position where the edge bands adjacent to the front edge 7 are to be separated. In order to separate only the narrow edge band, the front edge 7 passes through the work gap 5 but is not seated in the transmission 2. The actuating gap 5 is formed by two parallelly opposite outer edges of the fixing part 1 and the delivery part 2, the alignment of which is the same as the running direction of the tool heads 3, 4.

The width a of the working gap 5 is the laminated glass plate 6, in which the laser beam and the coolant jet are seated from the lower part along the desired separation line between the fixing part 1 and the delivery part 2 using the lower tool head 4. Determined by the clearance required to

In the processing from the top using the upper tool head 3, the delivery part 2 is installed in the fixing part almost without gap.

In figure 3, the stationary part 1 of the workbench is shown in a perspective view.

The seating surface of the fixing part 1 is formed by a plurality of suction surfaces 8 cut by the groove 9, and a seating bar 10 is formed in the rear region. The seating bar 10 is provided with holes connected to a compressed air source. Thus, the seating bar 10 can be operated as an air bearing while moving the laminated glass plate 6 in the direction of the delivery part 2.

Indeed, as already described in the description of known work benches, the groove 9 is necessary for the sledge gripper to be moved therein, and the laminated glass plate 6 is connected to the sledge gripper at its own end edge. It is fixed. While carrying the laminated glass plate 6, the sledge gripper is inserted into the groove 9 through the seating bars 10. At this time, compressed air exits through the hole and into the suction surface (8). Thus, an air cushion is formed on the suction surface 8 in order to transport the laminated glass plate 6 to each next operating position without damage.

The delivery part 2 shown in the front region in FIGS. 2a and 2b is substantially related to the formation and acting manner of at least the seating surface and is formed similar to the fixing part 1, with one practical difference. There is this.

The difference is that flap assemblies 11 are respectively provided below the grooves 9 adjacent to the delivery part 2 and the groove ends lead to relatively large recesses 12. The recesses 12 are each provided with a rotary flap 13 attached to the flap assembly 11.

4A and 4B show a possible embodiment of this flap assembly 11. The guided linear drive 14 is connected with a flap 13 which is rotatably disposed in a recess 12 in the delivery part 2 above the wing 16. The linear motion is converted into the rotational motion of the flap 13, the flap 13 pivoting between an upside down operating position and a downside down rest position, in which the top surface of the flap 13 is a working table. Is located in the plane of the seating surface.

The flap 13 connects the operating gap 5 in particular in the actuated position above the flap 13, for example in the absence of an operating gap 5, the fixing part 1 and the delivery part 2. Close the groove end of In both cases each fulfills the function according to the invention.

When machining from the bottom, sufficient working gap 5 must be provided at this time, in case of cutting of the narrow (narrower than half of the working gap width a) edge bands, the flaps 13 are each cracked. It is flipped upward with the formation. Thus, the portion projecting above the working gap 5 of the laminated glass plate 6 is mechanically supported from the bottom. Thus, it is possible to prevent the edge band from tearing unexpectedly and uncontrolled.

In processing from the top, the delivery section 2 is then installed adjacent to the holding section 1 almost completely without an operating gap 5, with the flap 13 flipped up in the direct area past the separation line. Continuous seating surfaces for (6) are to be considered and even heat dissipation by heat conduction is to be considered. Preferably, for the flap 13 a material having a thermal conductivity at least similar to the material forming the suction surface 8 in the fixing part 1 and the delivery part 2 is selected. The laminated glass plate 6 is preferably positioned such that the desired separation line proceeds above the delivery section 2.

The flap assembly 11, in particular the flap 13, is a substantial feature in which the device according to the invention is distinguished from the prior art.

Another practical difference is the placement of the presser 17. In FIG. 5, the presser 17 is shown as installed above the delivery part 2. The presser 17 is capable of running horizontally between the rest position shown above the delivery part 2 and the operating position above the operation gap 5 between the stationary part 1 and the delivery part 2. Thus, the presser 17 can be vertically lowered and tilted into the working gap 5.

The presser 17 has a length corresponding to the length of the working gap 5 determined by the width of the work bench. The width of the presser 17 is slightly narrower than the width of the working gap 5. Preferably, the presser 17 is made of a rigid material with the smallest possible bending and with the highest thermal conductivity possible. The presser 17 has several functions. Following the progress of the method the press 17 is first used as an abutment when mechanically placing a start crack on the side edge of the lower glass plate. Then, the presser 17 is not only used as a heat sink during the separation of the lower glass plate, but also laminated glass plates seated on both sides, in some cases, to separate the adhesive layer existing along the separation line between the glass substrates. It is used as a flexural beam for applying bending stress to the dividing line of (6).

The presser 17 can be implemented as a passive and active heat sink without degrading its function as a support or bending beam.

In the case of a passive heat sink, the compressor 17 is made of a bulk material piece with high thermal conductivity.

In an active heat sink, the presser 17 has a coolant tube and corresponding connection, for example for supply and guidance of coolant.

Passive heat sinks release absorbed heat relatively slowly by heat radiation so that they are only affected by ambient temperature, while active heat sinks remove heat by heat conduction to a coolant at a selectable temperature.

The heat dissipation can be controlled by the heat sink through the perfusion rate and temperature of the coolant, so it can be better optimized for process conditions.

As described above, the laminated glass plate 6 seated on the seating surface of the fixing part 1 and seated on the work table is only adhered to the upper part of the suction surface 8 of the fixing part 1 by the adhesion during processing. It is fixed. That is, the laminated glass plate 6 lies freely above the working gap 5 and loses intimate surface contact with the heat sink already present at the top during small bending due to gravity.

In order to ensure close contact between the presser 17 and the laminated glass plate 6 as a heat sink in the direct operating area, a pressure roller 15 is provided adjacent to the lower tool head 4. Preferably, four pressing rollers are each paired and installed before and after the active area of the lower tool head 4. The active area of the lower tool head 4 is to be understood as the area in which the tools, ie the laser beam and the coolant jet, act. The press roller 15 is provided such that the laminated glass plate 6 is pressed against the press 17 as a heat sink as close to the active area as possible in order to ensure as good heat dissipation as possible.

As described, the bending stress is applied to the separation line by the presser 17 with respect to the laminated glass plate 6 seated on both sides.

In order to separate the adhesive layer using bending stress along the dividing line which also borders the narrow edge band, the laminated glass plate 6 is seated on only one side, and the outer edge of the transfer part 2 which borders the working gap 5 is It can be tilted up and down or lifted up or folded down against the seating surface. For this, a +/- 3 ° inclination angle is already sufficient. Thus, the outer edge of the delivery part 2 may be bent downward to about 25 ° to guide the separated edge band seated on the delivery part 2 to a backup container.

The manner of operation of the above described apparatus is described in detail with reference to the description of the method implementation below.

Laminated glass plate 6, for example laminated glass plate 6 having a width of 1.30 m and a length of 1.50 m, consists of two glass plates each having a thickness of 0.2 mm, for example, two narrow edge bands , And a plurality of available bands having a width larger than the operating gap 5 of the device required for this.

The laminated glass plates 6 are prepared for the production of side-by-side liquid crystal displays each limited by a line of adhesive lines of several micrometers thick, which are enclosed in a rectangle. Not only when the laminated glass plate 6 is separated into individual fusible bands, but then when the fusible bands are separated and the displays are individually separated, the laminated glass plate 6 is separated between two parallel running adhesive lines, respectively. In addition, the adhesive line which proceeds perpendicularly thereto is also cut. That is, the dividing line guides not only across the glass-air-glass-layer structure but also across the glass-adhesive-glass-layer structure.

The method according to the invention allows for a high edge quality along the dividing line, despite the layer structure being justified for the challenges resulting therefrom and changing over the dividing line.

According to the method according to the invention, the laminated glass plate 6 is cut through three working steps:

First, the lower glass plate by means of laser beam and coolant jet from the lower part,

Then, the adhesive layer by bending stress acting on the separation line, and

Finally, the upper glass plate by laser beam and coolant jet from the top.

Specific realization of the individual operation steps, in particular, when separating the lower glass plate, is the laminated glass plate 6 seated on only one side, such as when the narrow edge band is separated, or on both sides, when the available band is separated? Since the steps of applying the bending stress differ depending on whether the method is different, the method should be described below for separating narrow edge bands and separating available bands.

The method of separating the narrow edge band is as follows:

In preparation for separating the lower glass plate of the laminated glass plate 6, the transfer part 2 is placed on the stationary part 1 of the workbench until it reaches a predetermined working gap 5 of width a, and the lower tool head (4) is positioned at the start position below one end of the operation gap (5). The laminated glass plates 6 to be separated are carried by the working gap 5, and the separating line for separating the edge bands is arranged in the center along the working gap 5. Subsequently, the laminated glass plate 6 is fixed at this position with the suction surface 8 in the fixing portion 1 upward. In order to separate only very narrow edges, the front edge 7 of the laminated glass plate 6 is freely positioned above the working gap 5, not seated on the seating surface of the delivery part 2. The presser 17 is located adjacent to the laminated glass plate 6 at the top of the working gap 5.

Preferably, in order to form a predetermined starting point of the crack along the dividing line, a starting crack is initiated at the edge of the lower glass plate, for example mechanically by a diamond wheel. Here, the presser 17 provides one support for the mechanical force when scribbing.

If the desired starting crack is not released, the crack may be formed from an existing micro crack, or after the microcracks have been placed, the lower tool head 4 may be activated and from the starting position along the working gap 5. The vehicle travels at a predetermined speed to an end position at the other end of the operation gap 5. The laser beam emitted causes the formation of exothermic and compressive stress along the desired separation line, and the subsequent progression of the heat depriving coolant jet causes the formation of tensile stress. When the threshold value of the breakdown stress of the glass is exceeded, cracks formed along the separation line occur in the glass. Process parameters, in particular the speed at which the lower tool head 4 moves to the laminated glass plate 6 (process speed), the length of the laser beam spot projected onto the glass surface, the spacing between the laser beam and the coolant jet And, the laser beam energy is professionally selected and the thickness of the glass substrate is adjusted so that the crack to be formed passes completely through the lower glass plate of the laminated glass plate 6 (separated crack). With the lower tool head 4 and at the same time the separation crack, the flaps 13 are flipped up from the down rested position to the operating position, which is then mounted on the laminated glass plate 6 from the bottom. Thus, the flap 13 supports a portion projecting above the working gap 5 of the laminated glass plate 6 and prevents the separate edge bands from being torn at random.

The presser 17 which remains in the upper part of the working gap 5 adjacent to the upper glass plate while the separating crack is formed in the lower glass plate is used as a heat sink during the separating process. That is, the heat generated by the laser is not removed by the subsequent coolant jet but by the heat sink as heat transferred to the upper glass plate of the laminated glass plate 6.

After separating the lower glass plate, in some cases, the adhesive layer connecting the lower and upper glass plates along the separation line must be separated.

The delivery part 2 lies in the fixing part 1 up to a residual gap of about 1 mm. Here, the flaps 13 remain in an upside down operating position and respectively enter into the grooves 9 of the fixing part 1. Attaching and connecting the laminated glass plate 6 by the suction surface 8 of the fixing part 1 is omitted, and the laminated glass plate 6 is seated of the fixing part 1 so that the separating line is located above the residual gap. Retreat to the side.

The laminated glass plate 6 is newly fixed on the suction surface 8 in the fixing part 1. Here, the edge band is freely seated on the seating surface of the delivery part (2). Subsequently, the outer edge of the transmission 2 bounding the working gap 5 is easily raised, so that a bending moment acting on the separation line occurs, which causes the adhesive layer to tear along the separation line. .

After the outer edge of the delivery part 2 is lowered again, the delivery part 2 can be installed almost completely in the stationary part 1. The minimum gap remains to prevent mechanical contact of the outer edges. The spacing between the fixing part 1 and the delivery part 2 may not change, and the laminated glass plate 6 is such that the separation line does not proceed between the fixing part 1 and the delivery part 2 and preferably, It is located to proceed above the delivery unit (2). The ends of the grooves which face each of the transmission part 2 and the fixing part 1 in a straight line are closed in the area around the dividing line by the flap 13. That is, the laminated glass plate 6 now rests on a seating surface that is end-to-end in the area around the separation line.

The upper tool head 3 is now installed at the end of the dividing line in the starting position. Similar to the operation of the lower tool head 4 described above, using the upper tool head 3 the upper glass plate is cut along the separation line.

After the edge band of the laminated glass plate 6 is completely separated, the transmission part 2 is pushed out of the fixing part 1. The edge band rests on the seating surface of the delivery part 2 and can be tilted into a waste container by, for example, a tilting operation of the delivery part 2.

Thus, the separation of the edge bands adjacent to the front edge 7 is finished.

When separating the edge bands adjacent to the distal edges, the remaining rest of the laminated glass plate 6 is the suction face 8 of the delivery part 2 instead of the suction face 8 of the fixing part 1 during the treatment. Maintained by).

The method of separating the available bands is as follows:

The preparation of the method differs from the preparation step for separating the edge bands, and is positioned above the working gap 5 so that the laminated glass plate 6 is seated on both sides of the working gap 5.

As described in the method of separating the narrow edge band, the adhesive layer is both ends after the lower glass plate is cut, and the flap 13 is not flipped up during the both ends.

For this purpose, the presser 17 is lowered into the working gap 5 so that the laminated glass plate 6 is bent about the separation line. The separating edges of the lower glass plate are pressed to separate from each other and the adhesive layer (adhesive point) tears while extending the separation crack. For this purpose, the presser 17 can be lowered parallel to the seating surface or preferably at an angle. Thus, the parallelly located adhesive points are torn to another side edge starting from the side edge of the laminated glass plate 6. The presser 17 is then raised again and returns to its rest position at the top of the delivery part 2.

Now, the transmission part 2 is installed in the fixing part 1 almost completely. At this time, the flaps 13 are flipped up in the operating position and respectively enter the grooves 9 of the fixing part 1. The straightly opposed groove ends of the delivery part 2 and the fixing part 1 are closed in the area around the separation line by the flap 13. In other words, the laminated glass plate 6 is seated on the seating surface leading to the one in the region around the separation line.

The upper tool head 3 is installed at one end of the dividing line in the starting position. Similar to the operation of the lower tool head 4 described above, using the upper tool head 3 the upper glass plate is cut along the separation line.

The completely separated available band is now carried over the delivery part 2.

The aforementioned method steps of separating the soluble band from the laminated glass plate are repeated. Here, the laminated glass plates 6 are respectively seated on both sides of the separation line until an edge band at the distal edge is made.

Those of ordinary skill in the art are not limited to the features of the embodiments described above by way of example, but the invention is not limited to other specific embodiments without departing from the scope of the invention as identified in the appended claims. It will be appreciated that it can be implemented.
