Description

  The present invention relates to a device for splitting (splitting) a liquid crystal panel.

  Various methods are already known as conventional methods for obtaining a product-sized panel by sequentially breaking a large liquid crystal panel. (For example, see Patent Documents 1, 2, and 3).

Japanese Patent No. 3759450 Japanese Patent No. 3969992 Japanese Patent No. 5256554

By the way, the split for the division | segmentation of patent document 1 is a hitting splitting system using a bar material or a roll.
The split in Patent Document 2 is a hitting method using a roll as a split member.
The split in Patent Document 3 is a hitting method using a folding bar.

When the above-described splitting method is adopted for panel splitting in recent times, various problems occur.
In other words, recent liquid crystal panels have a very fine structure (by reducing the thickness of each laminated substrate and electrode film as much as possible to reduce weight and cost). Cracks may occur in parts other than the split, causing defective products, and because the internal wiring is fine, disconnection occurs due to impact of hitting, etc., resulting in defective products. Accordingly, it is necessary to remove the adhered cullet.

  In particular, the terminal material is removed to remove the edge material along with the split and expose the electrode to the edge of the panel. At this time, the edge material of the unnecessary material (waste material) is removed from the exposed panel surface. When the sliding movement is performed while in contact with the terminal, the terminal surface is damaged (disconnected), resulting in a defective product.

  In addition, if a method of reversing the panel is used to scribe and fold (split) both sides of the panel (one side TFT and the other side CF), the panel having a fine structure as described above. In this case, the panel bends as it is turned over, which causes a defective product due to the occurrence of cracks due to the cutting of the wiring or the ultrathinning.

  In particular, if the panel is divided into large parts and then the product line, the line is divided into small lines, and the small parts are intermittently split, resulting in a significant reduction in efficiency and deterioration of productivity.

For this reason, there are problems such as an increase in cost.

Next, a first embodiment of the present invention will be described with reference to the accompanying drawings.
The large-sized liquid crystal panel A shown in FIG. 1 of this device has a laminated structure of an upper cell substrate, a liquid crystal as an electrode, and a lower cell substrate, as is known. When splitting (dividing) into single pieces, a large cutting line 2 is formed on the upper surface of the upper A surface (substrate 1), with both side edges connected in parallel, connecting both front and rear edges (on the side edges). Parallel parallel cutting lines 3 are scribed.

  As a method of scribing the cutting lines 2 and 3, for example, as shown in FIG. 2, a large liquid crystal panel A is supplied onto the stage 4 and sucked and supported (not shown), and then the gate frame 6 is mounted on the rail 5. When the portal frame 6 is caused to travel in one direction by, for example, a linear motor 8 as a traveling means for causing the slider 7 at the lower end of both sides to slide freely and travel in the front-rear direction, the parallel first cutter is operated by the action of the cylinder 9. The lower cutting line 3 is scribed by lowering 10, and is provided on a horizontal member of the gate-shaped frame 6 so that the slider 12 is slidably engaged with the rail 11, and as a traveling means for traveling in the lateral direction. For example, when the support member 14 is caused to travel in one direction by the linear motor 13, the second cutter 16 is lowered by the action of the cylinder 15. Cutting line 2 is scribed.

Further, a large cutting line 18 is scribed on the surface of the lower substrate 17 of the liquid crystal panel A.
For example, as shown in FIG. 4, the scribing of the major cutting line 18 is provided with a horizontal lateral rail 22 in front of the head of a belt conveyor 21 that conveys a large liquid crystal panel A, and a support member is provided on the rail 22. 23, the slider 24 is slidably engaged, and the support member 23 is caused to travel in the left-right direction by, for example, a linear motor 25 serving as a traveling means that travels in the lateral direction provided with the rail 22 and the slider 24. As the third cutter 27 is raised by the action of the cylinder 26 as the vehicle travels, the major cutting line 18 of the major liquid crystal panel B is scribed on the surface of the B-side substrate 17, but this is not a limitation. It is also conceivable that the liquid crystal panel A before being supplied to the belt conveyor 21 is scribed in advance.

  Furthermore, before the head of the belt conveyor 21, a first break means C is provided below the carrier belt for breaking (dividing) the major cutting line 2 of the liquid crystal panel A as it rises.

  As shown in FIG. 5, the break means C includes front and rear break plates 32, 32, which have opposite end portions in the front-rear direction opposite to each other with their base edges opposed to each other via a support shaft 31. The cylinder 33 is configured to push up both the break plates 32 and 32. After the major cutting line 2 of the liquid crystal panel A is aligned immediately above the opposed leading edges of the break plates 32 and 32, the cylinder 33 is extended. Thus, while the liquid crystal panel A is pushed up together with the belt of the belt conveyor 21 as the leading ends of the break plates 32 and 32 rise, the major cutting line 2 is broken along with the pushing up.

  Further, in front of the third cutter 27, the liquid crystal panel A conveyed by the belt conveyor 21 slides on the guide plate 34 and the leading end rides on the large swing table 35.

  In the above-mentioned large swing table 35, the opposite side of the guide plate 34 is lifted and lowered by, for example, the extension action of the cylinder 36 as a lower lifting means, and the liquid crystal panel A is pushed up as it is raised, so that the large cutting line 2 is folded. Divide (divide).

  At this time, the rear side of the upper surface major cutting line 2 of the liquid crystal panel A is slid up and down by the guide means 37, and the upper surface of the liquid crystal panel A is pressed by the backup bar 39 which is lowered by the action of the cylinder 38. The large cutting line 2 can be smoothly broken.

  The large swing table 35 is slid forward by the guide means D as the large swing table 35 is pushed up by the action of the cylinder 36.

  The reason is that the split large panel A-1 is pushed forward in accordance with the slide of the swing table 35, and the electrode having the exposed cut end is not damaged by the pushing.

  The guide means D includes a protruding piece 40 that protrudes downward on both sides of the swing table 35 on the backup bar 39 side, and a long hole that is provided on the protruding piece 40 so that both ends are positioned up and down and the lower end faces obliquely backward. 41 and a trochanter 43 that is supported by a standing column member 42 and penetrates the long hole 41, and the large swing table 35 is forced by the long hole 41 as the large swing table 35 is tilted upward. It is designed to slide forward.

  The large liquid crystal panel A-1 on the large swing table 35 associated with the above large two is a double-conveyor 45 in which the tail side is inserted into a notch 44 facing rearward from the front edge of both sides of the large swing table 35. It will be sent forward with the driving.

  The large liquid crystal panel A-1 sent out on the conveyor 45 is picked up by the first transfer machine E, then rotated 90 degrees, and then transferred forward and then dispensed.

  As shown in FIGS. 4, 9, and 10, the first transfer machine E includes a horizontal frame 46 in the front-rear direction and a slider 48 that is slidably engaged with a rail 47 that is provided on the entire side surface of the frame 46. And a motor 50 installed on the traveling body 49 turn 90 degrees below the traveling body 49, move up and down by the action of the cylinder 51, and suck the large liquid crystal panel A-1 on the lower surface. A suction box 53 with a suction hole 52 to be held (connected to a suction hose) and, for example, a linear motor 54 as traveling means for causing the traveling body 49 to travel in the front-rear direction are configured. Is lowered and the large liquid crystal panel A-1 on the conveyor 45 is sucked and supported on the lower surface of the suction box 53, and then the suction box 5 is operated by the action of the cylinder 51. Increases the load receiving large split liquid crystal panel A-1 with and by which the suction box 53 is pivoted 90 degrees by the motor 50, changing the direction of the suction support large split liquid crystal panel A-1 in the longitudinal direction.

  In the figure, 55 is a lifting guide, and 56 is a camera that detects the accurate 90-degree turn transfer of the large liquid crystal panel A-1.

  In addition, the large liquid crystal panel A-1 is received from the lower side of the suction box 53 at the unloading position and forwarded to the upper surface, and is sucked and supported by the suction hole 57 connected to the suction hose. In addition, a transport stage 58 is provided that travels back and forth in the front-rear direction by the travel means.

  The transport stage 58 is configured to slidably engage the sliders 60 on both sides of the lower surface with the rail 59 in the front-rear direction and to travel by, for example, a linear motor 61 as advance / retreat traveling means.

  Furthermore, a carry-out conveyor 62 is provided forward from both sides of the forward stop position of the transfer stage 58.

  As the suction stage 63 descends, the large liquid crystal panel A-1 on the transport stage 58 that has stopped moving forward is sucked into the suction hole 70 on the lower surface, lifted after receiving the cargo, and then moved forward and backward to the outside of the carry-out conveyor 62 by the transverse traveling means. Two traversing traveling bodies 64 are provided.

  As shown in FIG. 11, the traversing traveling body 64 slidably engages a slider 67 of the traversing traveling body 64 with a rail 66 of a horizontal frame 65, and moves in the left-right direction by a linear motor 68 as traversing traveling means. The suction stage 63 is moved up and down by the action of the cylinder 69 on each traversing traveling body 64.

  Then, as shown in FIG. 13, the large liquid crystal panel A-1 on the transport stage 58 is sucked and supported on the lower surface of one suction stage 63 lowered by the action of the cylinder 69, and then carried out by the linear motor 68. The suction stage 63 is traversed outside 62.

  The next large liquid crystal panel A-1 is transported forward by the transport stage 58 along with this traversal, so that the large liquid crystal panel A-1 on the transport stage 58 is traversed to another empty space (the traversing traveling body 64). The suction liquid is received on the lower surface of the suction stage 63, and the large liquid crystal panels A-1 are alternately transferred together with the suction stage 63 while the traversing traveling body 64 travels outward after receiving the goods.

  In the middle of transferring the large liquid crystal panel A-1 to the outside, a parallel base 70 (base 70 is a base 70) that can be adjusted by each linear motor 68 as a lateral movement means provided in the horizontal slide portion with the front and rear parallel intervals. As is known in the art, the linear motor 73 can be used to adjust the parallel interval while traveling in the front-rear direction of the figure), and the third liquid crystal panel A-1 is moved up and down through the cylinder 71. Scribing the small cutting line 74 in parallel with the lower surface of the B surface.

  The large liquid crystal panel A-1 on the carry-out conveyor 62 is aligned (pressed rollers or the like disposed outside the two sides) before scribing by the third cutter 73 so that the two sides in the carry-out direction are parallel to the carry-out direction. )

  After the scribing, the large liquid crystal panel A-1 travels to a position directly above the conveyance stage 58, then lowers the suction stage 63 by the extension action of the cylinder 69, and releases the suction to make a small cut on the conveyance conveyor 62. A scribe large liquid crystal panel A-1 of line 74 is transferred.

  According to the procedure described above, the large liquid crystal panel A-1 sequentially conveyed is distributed to the left and right by the suction stage 63 and returned to the carry-out conveyor 62 after the small scribing, so that productivity can be remarkably improved.

  As shown in FIGS. 3 and 14, the scribed large liquid crystal panel A-1 on the carry-out conveyors 62 and 62 is transferred toward the head of the carry-out conveyor 62, and below the carrier belt of the carry-out conveyor 62 when the transfer is stopped. The small cutting line 2 is broken by the second break means 75 arranged on the side.

  Since the second break means 75 is the same as the first break means C, the configuration and the action of the break are omitted.

  Further, on the front side of the head of each carry-out conveyor 62, there is provided a small swing table 76 that divides (divides) the large liquid crystal panel A loaded from the carry-out conveyor 62 into the product size sequentially from the leading end.

  The cylinder 36 as an elevating means for tilting the split swing table 76 up and down and the small swing table 76 are slid forward as the split swing table 76 is tilted upward (this slide is the exposed terminal surface associated with the split). Since the guide means D is the same as the large swing table 35 side, its illustration and description of the configuration are omitted.

  Of course, a backup bar is arranged on the upper side in front of the small swing table 76, but the illustration and operation are the same, and the description is omitted.

  The split liquid crystal panel A-2 on the split swing table 76 is paid out by the conveyor 45 whose tail side is fitted into the notch 44 in the same manner as the large swing table 35 side.

  As a result, it distributes from the major line to both the left and right minor lines to achieve a significant efficiency improvement.

Next, a second embodiment of the present invention will be described with reference to the accompanying drawings.
