Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass processing apparatus for obtaining a liquid crystal panel of a product size by scribing on both sides of a liquid crystal panel and cutting along the scribed line.

[0002]

2. Description of the Related Art In order to cut a glass plate, a scribe line is cut on the upper surface of the glass plate using a glass scriber, and the glass plate is turned upside down. By slightly bending the glass plate into a V-shape, vertical cracks generated during scribing are further grown and broken. First, the configurations of the glass scriber and the break machine will be briefly described.

In the glass scriber 11 shown in FIG.
Table 12 (in this view behind) Y direction together with the rotation in the θ direction (arrow J ₁ direction) to move to. The table 12
A glass plate 1 to be processed is suction-fixed to a table 12 by vacuum suction. By recognizing the alignment marks written on the glass plate 1 with the pair of CCD cameras 13, a positional shift at the time of setting the glass plate 1 is detected. For example, when the glass plate 1 is shifted by an angle θ, the table 12 is rotated by −θ, and when the glass plate 1 is shifted by Y, the table 12 is moved by −Y. A guide bar 14 extends in the X direction above the table 12,
The scribe head 15 reciprocates along the guide bar 14 by the cutter shaft motor 16. A chip holder 17 is provided at the lower part of the scribe head 15 so as to be vertically movable and swingable, and a cutter wheel is provided at the lower end of the chip holder 17 as shown in a partially enlarged view circled in the figure. A tip 18 is rotatably mounted.

[0004] The chip holder 17 is lowered, and the scribe head 15 is moved while the cutter wheel chip 18 is pressed against the surface of the glass plate 1 with a predetermined pressure (this force is referred to as a scribe load).
A scribe line in the X direction is carved on the upper surface of the table, and this scribing operation is repeated each time the table 12 is moved in the Y direction, whereby scribe lines in the X direction are carved one after another. Next, the table 12 is moved to 9 by a driving source (not shown).
By performing a similar scribe operation after turning by 0 °, a scribe line in the Y direction is formed this time.

FIG. 2 is a view of the break machine 21 as viewed from the front. Table 22 is configured to rotate θ in the direction (arrow J ₃ direction), along the two rows of rails 23 to move in the Y direction (toward the vertical direction). On the upper surface of the table 22, the scribed glass plate 1 is suction-fixed to the table 22 with the scribe surface facing down. Above the table 22, an air cylinder 24 is provided on the frame 25 with its cylinder shaft 24a facing downward. A moving member 27 that can move up and down along two shafts 26 is attached to the lower end of the cylinder shaft 24a, and a pressing bar 28 made of an elastic body and attached to the moving member 27 is attached.

The table 22 is moved so that the scribe line is located immediately below the pressing bar 28, and then the pressing bar 28 is lowered and pressed against the glass plate 1, whereby the glass plate 1 is moved along the scribe line. Break.

[0007] Since the liquid crystal panel to be processed in the present invention is formed by laminating two glass plates, it is necessary to individually scribe and break each glass plate. In order to divide the glass substrate into product sizes, for example, as shown in “Method of cutting laminated glass substrate” in JP-A-6-48755, (a)
The upper glass plate 1 is scribed by a glass scriber using a cutter wheel, (b) the liquid crystal panel is inverted, and (c) the lower glass plate 1 'is pressed against the upper glass plate 1' by a break machine. Is broken along the scribe line, (d) the glass plate 1 'is scribed, (e) the liquid crystal panel is inverted, and (f) the glass plate 1 positioned above is broken. By pressing with a machine, the lower glass plate 1 'is broken along the scribe line, whereby the liquid crystal panel is divided into a desired size.

In summary, (a) scribe upper 1 (b) reverse (c) break lower 1 (d) scribe upper 1 '(e) reverse (f) break lower 1' However, apart from this, as the prior art of the above-mentioned publication, (a) scribe the upper one (b) invert (c) scribe the upper 1 '(d) break the lower one (e) invert ( f) The process of breaking the lower 1 'is also introduced.

[0009]

As described above, in each case, the breaking step and the reversing step are each required twice, which not only complicates the system (equipment cost and work space) but also increases the system complexity. There was a problem that productivity was not good.

Accordingly, an object of the present invention is to solve these problems.

[0011]

Means for Solving the Problems The present applicant has filed a previously filed "Glass Cutter Wheel" (Japanese Patent Application Laid-Open No. 9-188534),
It discloses that by forming extremely fine irregularities on the cutting edge (circumferential ridge) of a normal cutter wheel, a deep vertical crack was obtained at the time of scribing. After that, various glass panels were scribed using this glass cutter wheel, and the scribe performance was actually checked. Was found to be divided. Thus, the present inventors have invented a glass processing apparatus which eliminates the need for a breaking step which is indispensable after the scribing step.

[0012]

According to the novel glass processing apparatus of the present invention, (a) the upper glass plate 1 is scribed by a glass scriber, (b) the liquid crystal panel is inverted, and (c) the upper glass plate 1 'is Glass scriber (the same glass scriber in claims 3 and 4)
It consists of a scribe process for both glass plates and only one reversal process, eliminating the break process.

If the liquid crystal panel is divided only in the scribing process as described above, the ordinary suction cup must be used to carry out the liquid crystal panel divided into individual panel pieces to the next process by the removing means after the final scribing. The individual material pieces cannot be stably sucked and held by the material removing means. Therefore, in the present invention, a material removing means having a large number of fine suction ports in the suction portion is used, and a "vacuum suction pad" is employed in the following embodiments.

It should be noted that the glass scriber may be provided with an auxiliary pressing means in such a case that the glass scriber may not be separated by scribe alone depending on the application accuracy of the adhesive used in manufacturing the liquid crystal panel or the like. After the scribing, the liquid crystal panel may be pressed using the pressing means.

[0015]

FIG. 3 is a system diagram of a glass processing apparatus showing a first embodiment of the present invention. 2 is a liquid crystal panel that is placed on the sheet material section Z _1, has been bonded to the glass plate 1, 1 'as described above will be described later in detail its construction. The liquid crystal panel 2 is conveyed to the first glass scriber 11 by the material supply robot. This glass scriber 11 has the same mechanism as that shown in FIG. 1, but the cutter wheel tip 18 'used here has fine irregularities on its cutting edge, and the details are shown in FIG. Show.

As shown in the enlarged view, a U-shaped or V-shaped groove 18b is cut out in the blade ridge 18a of the cutter wheel tip 18 'so that a protrusion j having a height h is formed at a pitch P. It is formed at intervals. The specific numerical values are exemplified below. Wheel diameter: 2.5 mm Wheel thickness: 0.65 mm Blade edge angle: 125 ° Number of protrusions j: 125 Height of protrusion j: 5 μm Pitch p: 63 μm Blade load: 3.6 Kgf Scribe speed: 300 mm / sec

After the liquid crystal panel 2 on which one glass plate 1 has been scribed is inverted by the glass scriber 11, the second
The transport reversing machine U transports to the glass scriber 11 ′ of FIG. 5 and includes a transport reversing robot 31 shown in FIG. 5 and a table 41 of FIG. 6 on which the liquid crystal panel 2 is temporarily placed.

[0018] In the transport inversion robot 31 in FIG. 5, the rails 32 extending in the horizontal direction is supported by the vertical movement (arrow J ₄ directions) and pivotable (arrow J ₅ direction) by a driving source (not shown) . The movable base 3 along the rail 32
3 is located, the arm 34 projecting from the movable base 33 in the horizontal direction are provided on the shaft rotatable (arrow J ₆ directions). At the tip of the arm 34, a pair of suction cups 35 that are opened upward and downward, respectively, are provided. Further, the transport reversing robot 31 itself is movable.

The mounting table 41 shown in FIG.
2 and 43 are provided vertically, and support plates 42 and 43 are provided.
When the handle 44 is turned, the distance between the two support plates is changed in accordance with the size of the liquid crystal panel 2 by moving in parallel in directions opposite to each other.

The liquid crystal panel 2 is sucked by the suction cup 35 on the lower side of the transport reversing robot 31, the arm 34 is rotated by 180 ° to lift the liquid crystal panel 2, and the support plates 42 and 43 of the table 41 are Place on top. After the suction is released, only the suction cup 35 is moved, and the suction cup 35 sucks the liquid crystal panel 2 from above and transfers the liquid crystal panel 2 to the table 12 of the next glass scriber 11 ′. Set.

The glass scriber 11 'for scribing the other glass plate 1' of the inverted liquid crystal panel 2 has the same structure as the glass scriber 11 described above. Liquid crystal panel 2 that both surfaces are scribed, the material removing robot, is carried out to the material removing unit Z _2. Note that, in the present invention, 11, 1
Since the same type of glass scriber is used as in 1 ′, S1, S1,
Name it as S2.

By the way, in the liquid crystal panel 2 scribed on both sides, a panel piece 2 'is almost always divided at that time, as described later. Therefore, when such a panel piece 2 'is sucked by the suction cup 35 of FIG. 5, each panel piece 2' cannot be stably sucked, and the panel pieces collide with each other. In order to stably suck the individually divided panel pieces 2 ′, instead of the suction cup 35, the “vacuum suction device” disclosed in “Vacuum suction device (Japanese Patent Application No. 9-175602)” previously submitted by the present applicant was used. The use of suction pads is optimal. Here, we introduce the "vacuum suction pad".

FIG. 18 shows a transfer robot 141 using a vacuum suction pad 121. The suction plate 122 is joined to the iron holding member 126 using a magnet sheet,
The holding member 126 is mounted on the horizontal arm 142 of the transfer robot 141 by the support member 126a, and the suction pipe 127 inserted through the support member 126a is connected to the suction plate 122. FIG. 19 is a plan view of the suction plate 122. A photosensitive resin material is used as a material, and other portions are formed in the suction portion indicated by 122b so that a large number of independent fine protrusions M are formed as shown in an enlarged view of a region indicated by X. Is etched to form a concave portion N. A suction port 122c is opened at the center of the suction board 122, and a suction pipe 127 is connected to the suction port 122c. 122 shown in the suction cup 122
The portion a is a non-etched region and this portion becomes an airtight portion. Needless to say, a suction pad formed so as to be able to suck the entire surface of the work is used. When this vacuum suction pad 22 is used in place of the suction cup 35, each panel piece 2 'is suctioned by suction holes formed by a large number of recesses, so that each panel piece 2' is stably sucked, and the panel pieces are separated from each other. I don't even meet. Note that the same feeding robot as the transfer reversing robot 31 in FIG. 5 can be used as the above-mentioned feeding robot.

The operation of the above system will be described with reference to the flowchart of FIG. The liquid crystal panel 2 on the sheet material section Z ₁ is set to the glass scriber S1 at step S1. At this time, the table of the glass scriber S1 is R1.
The liquid crystal panel 2 has been moved to a rear position (upward in the figure) indicated by reference numeral 2 and is received at this position and fixed by vacuum suction. After that, the table 12 moves to the position of the table indicated by F12, and at that position, the table 12 rotates and moves as described above, and the positional deviation at the time of setting the liquid crystal panel 2 is corrected.

In step S2, the scribe head 15 moves in the X direction based on the processing data set and input in advance, and thereby the X-ray of the upper glass plate 1 of the liquid crystal panel 2 is moved.
An axis is scribed, and this operation is performed every time the table 12 is moved in the Y direction. When the scribe in the X-axis direction is completed in this way, the table 12 is rotated by 90 ° in step S3.

The glass plate 1 is scribed again in the Y-axis direction by being scribed again in step S4. When the scribing in the X-axis direction and the Y-axis direction is completed in this way, the table 12 retreats again, the liquid crystal panel 2 is released from the vacuum suction at the position of R12, and then inverted using the transport reversing robot 31 and the table 41. The liquid crystal panel 2 with the glass plate 1 'on the upper side is a glass scriber S
It is set on the table 12 moved to the rear of 2.

In step S6, the glass scriber S2 scribes the glass plate 1 'in the Y-axis direction (rotated 90.degree. From when the liquid crystal panel 2 is set on the glass scriber S1). After the table 12 is rotated by 90 degrees in step S7, the glass plate 1 'is scribed in the X-axis direction in step S8. With such X in two glass plates 1, 1 'of the liquid crystal panel 2, the scribe in the Y-axis direction is completed, the liquid crystal panel 2 by the material removing robot is carried out to separate the material removing unit Z _2.

As described above, when scribed by the cutter wheel tip 18 having fine irregularities on the cutting edge, a deep vertical crack penetrating to the lower surface is obtained. In some cases the scribe line is naturally divided. Even if this is not the case, when vacuum suction is released for carrying out the liquid crystal panel 2 by the glass scriber S2, there is a delicate imbalance in the vacuum release at each suction point, so that the liquid crystal panel becomes a stress. 2, a slight shock force is applied when the suction cup of the material removal robot comes into contact with the liquid crystal panel 2. When the liquid suction panel sucks the liquid crystal panel 2, a slight imbalance of the suction force at the suction point occurs. added as stress, shock force is applied even when placed suction release to the material removing unit Z ₂ and acts factors equal, the liquid crystal panel 2 along a scribe line on the material removing unit Z ₂ It is completely separated and does not require a break process by a break machine.

FIG. 8 is a system diagram showing a second embodiment of the present invention. In this embodiment, one glass scriber 11 (S3) is used, and the glass scriber S3 scribes both sides. And the table 41 of FIG.
Is provided with an intermediate table 46 having. The reversing robot 45 is substantially the same as the transport reversing robot 31 shown in FIG.

The operation of this system will be described with reference to the flowchart of FIG. When the liquid crystal panel 2 on the material removing unit Z ₁ at step S11 is set on the table 12 in a position F12 in a glass scriber S3, after being secured to the table, the positional deviation at the time of setting modification by vacuum suction Is done.

In step S12, the glass plate 1 on the upper side of the liquid crystal panel 2 is scribed in the X-axis direction. In the next step S13, the table 12 is rotated by 90 °.

In step S14, the glass plate 1 is scribed again in the Y-axis direction. When the scribing of the glass plate 1 in the X-axis direction and the Y-axis direction is completed, in step S15, the table 12 is retracted again, and the liquid crystal panel 2 is released on the intermediate table 46 by the reversing robot 45 after the vacuum suction is released. And is returned to the table 12 located at R12.

In step S16, the glass plate 1 'is scribed in the Y-axis direction by the glass scriber S3. After the table 12 is rotated by 90 ° in step S17, the glass plate 1 ′ is scribed in the X-axis direction in step S18. With this completion of X, scribe in the Y-axis direction all the two glass plates 1, 1 'of the liquid crystal panel 2, the liquid crystal panel 2 by the material removing robot is carried out to the material removing unit Z _2.

In the embodiment shown in FIGS. 3 and 8, the liquid crystal panel 2
Was divided into four parts to obtain panel pieces, but FIG. 10 shows a liquid crystal panel 2 divided into six parts. FIG. 11 is a partially enlarged view of a side section taken along line AA. A-A and B-
As shown in the side sectional view of B, transparent glass particles (not shown) are sealed as spacers to separate the upper glass plate 1 and the lower glass plate 1 'by a predetermined gap G. The two glass plates 1, 1 'are fixed to each other by an adhesive 51 provided along the periphery of the panel piece 2' of each product size. However, in order to inject the liquid crystal into the gap area divided into the product size by the adhesive 51, an injection hole 52 provided with a cut such as “┘└” is formed by the same adhesive. In each panel piece 2 ', electrodes 53 are formed on two sides (some also have only one side) of one glass plate.

FIG. 12 is a partially enlarged view of the sectional view taken on line AA of FIG. 10, and W indicates a break surface. As can be seen from FIG. 1 and the lower glass sheet 1 'are different in the scribed portions.

By scribing and breaking such a portion of the liquid crystal panel 2 suitable for the glass sheets 1 and 1 ', a panel piece 2' is obtained as shown in FIG. Note that “4 divisions” and “6 divisions” are merely examples of “small” and “many” division numbers, and are not actual division numbers.

[0037] Now, in FIG. 10, focusing the scribe line L _1, the inlet 52 and traverses, thus, even if they are separated at the point of this line L ₁ by the scribing adhesive at the inlet 52 Thereby, the bisected glass sheets remain fixed to each other. Therefore, when the number of the injection ports 52 is large (that is, when the number of divisions is large), it is difficult to be divided into the panel pieces 2 ′ only by the scribe operation. Further, as shown in FIG.
It is difficult to cut only by scribing even if the construction accuracy is poor (when the adhesive straddles both sides of the dividing line) or the type of adhesive.

In such a case, it is necessary to perform an auxiliary pressing step to give a shock. FIG. 14 shows a glass scriber 1 provided with a breaking mechanism B1 therefor.
1 "in the (S ₄₎ and is shown. Figure 14, the breaking mechanism B1 is scribing mechanism (this mechanism is the same as FIG. 1)
Behind, an air cylinder 61 and a pressing bar 62 that moves up and down by its drive.

A system diagram using the glass scriber S ₄ is shown in FIG. 15 as a third embodiment of the present invention. In FIG. 15, the process flow is as follows:
,... The operation in this case will be described with reference to the flowchart of FIG.

[0040] When the liquid crystal panel 2 on the sheet material portion Z ₁ at step S21 is set on the table 12 in a position F12 in a glass scriber S4, after being secured to the table by vacuum suction, the position at the time set The deviation is corrected.

In step S22, the glass plate 1 above the liquid crystal panel 2 is scribed in the X-axis direction. In the next step S23, the table 12 is rotated by 90 °.

In step S24, the glass plate 1 is scribed again in the Y-axis direction. When the scribing of the glass plate 1 in the X-axis direction and the Y-axis direction is completed, in step S25, the liquid crystal panel 2
Is reversed by the reversing robot 45 located downstream and returned to the table 12.

In step S26, the glass scriber S4 scribes the glass plate 1 'in the Y-axis direction. After the table 12 is rotated by 90 degrees in step S27, the glass plate 1 'is scribed in the X-axis direction in step S28. When all the scribes in the X and Y-axis directions have been completed on both the glass plates 1 and 1 'of the liquid crystal panel 2 in this way, the table 12 sets R12 in step S29.
Retreat to the position. At this time, the liquid crystal panel 2 is aligned so that the scribe line L ₁ to be pressed (shown in FIG. 10) matches the rod direction of the pressing bar 62. The liquid crystal panel 2 is completely separated by the pressing of the pressing bar 62. In step S30, the liquid crystal panel 2 which is separated by the material removing robot is carried out to the material removing unit Z _2.

The flow in FIG. 16 is an example in which the pressing is performed after the completion of all the scribes. However, as shown in FIG.
In the case where the glass sheet 1 is straddled at a part where the glass sheet 1 is divided, after the glass sheet 1 is scribed, pressing may be performed for breaking the glass sheet 1, and a flowchart in that case is shown in FIG.

In the present glass processing apparatus, the break step can be omitted by using a cutter wheel chip having excellent scribe performance. However, if it has the same effect as this cutter wheel chip, it can be used. Thus, the glass processing apparatus of the present invention can be completed. As examples, those using a laser beam and those using an ultrasonic wave have been proposed. These are introduced here for reference.

The "fragile material cutting method and apparatus" disclosed in Japanese Patent Application Laid-Open No. 9-150286 discloses a beam gun 151 which irradiates an elongated laser beam spot 153 on the surface of a glass sheet 152 with a beam gun 151 as shown in FIG. By moving 151 in the longitudinal direction of the beam spot, a crack 155 is generated on the surface of the glass sheet,
A water jet is jetted from the nozzle 154 following the moving beam spot, and the glass sheet is rapidly cooled to generate strain stress, so that the generated crack is further grown.

As shown in FIG. 21, the "ultrasonic cutting apparatus" disclosed in Japanese Patent Application Laid-Open No. 61-260996 has a magnetic field generator 202 provided at the upper end of a magnetostrictive element 201 which vibrates in one direction in accordance with a change in magnetic force. A cutter 203 is attached to a lower end of the magnetostrictive element 201. By passing an alternating current of a frequency suitable for the magnetic field generator 202, the magnetostrictive element 201 vibrates in the vertical direction in the figure, and the vibration is transmitted to the cutter 203, whereby the workpiece 204 is cut efficiently. The processing object here is a cloth or a sheet material, but it has been confirmed that a deep vertical crack is generated by applying the same vibration to a diamond chip or a cutter wheel chip for a glass scriber.

[0048]

As described above, according to the present invention, by using a glass scriber employing a cutter wheel tip having excellent scribing performance, a vertical crack almost penetrating the plate thickness can be obtained. This makes it possible to omit a break step which has been indispensable after scribing, thereby simplifying the steps, increasing the processing speed, and simplifying the system configuration.
In addition, when the liquid crystal panel after the scribe is finished, that is, when a large number of individually divided panel pieces are carried out, a large number of fine suction ports are provided in the suction portion of the material removing means, so that the panel pieces can be stably sucked. .
