An embodiment of the present invention will be described with reference to the accompanying drawings.
A shown in FIGS. 1 to 5 is a strip-shaped large panel.
As described above, the large panel A is juxtaposed between the cutting lines 3 for the frame end material and the both cutting lines 3 on the upper surface of the substrate 1 on both short side edges of the upper surface of the two laminated upper substrates 1. The cutting edge 4 for the split (product size) is scribed, and the long side edge of the upper substrate 1 is formed so that one side of the long side edge of the laminated lower substrate 2 is exposed to become the terminal portion X of the electrode. (When the end material separation cutting line scribed on the long side edge of the upper substrate 1 is broken and the end material is removed), the upper substrate 1 is projected and formed.
The above-mentioned large panel A is formed by, for example, forming a large liquid crystal panel having a laminated structure of a CF cell substrate as the upper substrate 1, an electrode liquid crystal as the lower substrate 2, and a TFT cell substrate into a strip shape by breaking the cutting line. (For example, refer to FIG. 8 according to the method of Japanese Patent No. 3759450).
B shown in FIGS. 3 and 4 is a flexible bed on which the large panel A is placed. This flexible bed B is divided by the cutting line 4 as the loaded large panel A is pushed up from below ( This is because you can do it).
As shown in FIGS. 3 and 4, for example, the bed B is configured by spanning an endless belt 5 on pulleys (not shown) facing left and right. It may be a sheet or the like.
In addition, the traveling body 6 is made to travel on the upper and lower sides of the bed B by the traveling means C in an up-and-down manner with the cutting lines 3 and 4 sandwiched or between the cutting lines 3, 4 and 18 (with numerical control and mounting). The camera is stopped at the position of the cutting lines 3 and 4 by a camera), and is guided by the action of, for example, a cylinder 8 as an elevating means on the upper and lower sides sandwiching the bed B of the left and right opposing column members 7 of the frame F standing from the traveling body 6 The break bar 10 that is guided up and down by 9 is provided on the upper side, and a pressing bar 11 that is guided up and down by the guide 9 by the action of the cylinder 8 is provided as an elevating means, and the large panel A is lifted by the pressing bar 11 that descends. The break bar 10 that rises in the stopped state sequentially enters the cutting line 4 or the cutting line 18.
It is to be noted that the pressing of the one end of the large panel A and the other end are performed by arranging two holding bars 11 side by side (not shown in the figure) and by moving the two bars in synchronism with the cylinder 8 or moving up and down independently. Can do.
Further, the first traveling body 12 reciprocates between the upper side and the front side of the bed B by the traveling means C, and descends to the first traveling body 12 by the action of, for example, the cylinder 13 as an elevating means. A suction box 14 for sucking and holding (receiving) the upper surface of the treated large panel A on the bed B is provided by a hole (not shown).
A second traveling body 15 that reciprocates by the traveling means C is provided between the forward stop position of the suction box 14 and the front, and the suction box lowered by the action of the cylinder 13 on the second traveling body 15. A first stage 16 is provided which receives the 14 holding large panel A on the upper surface and sucks and holds it by a suction hole (not shown) on the upper surface.
Further, just above the traveling path of the first stage 16 is lifted up and down by, for example, the action of the cylinder 17 as a lifting means, and along with the lowering, the upper substrate 1 is cut in parallel with the end material separation cutting lines 18. A first cutter 19 arranged in parallel to scribe the cutting line 4 is provided.
As is well known, for example, as shown in FIGS. 3 and 4, the first cutter 19 is provided with a rail 21 on one side of a horizontal member 20, and a parallel position (interval) on the rail 21 by numerical control of the traveling means C. ) Can be slidably engaged, and a first cutter 19 is provided on each base 22 so as to move up and down by the action of, for example, a cylinder 17 as a lifting means.
As is known, a camera (not shown) is mounted on the base 22, and the scribe position of the cutting line 4 is detected by this camera, and the base 22 is stopped at an accurate position.
Further, as the traveling means C of each base 22 to be numerically controlled, a linear motor is provided on the rail 21 and the base 22, and the ball screw (not shown) of a female screw is reversibly driven by a servo motor, for example. Sometimes.
The third traveling body 24 reciprocates by the traveling means C between the position just above the forward stop position of the first stage 16 and the front, and the third traveling body 24 is moved up and down by, for example, a cylinder 25 as a lifting means. In addition, a suction second stage 27 is provided which is turned 90 ° by the turning means 26 and sucks and holds (receives) the large panel A on the first stage 16 by a suction hole (not shown) on the lower surface.
As the turning means 26, for example, a reversible rotation motor is used.
Further, the transport path 28 is provided in front of the forward stop position of the second stage 27, and the second stage 27 is lowered by the extension action of the cylinder 25, so that the large panel A is moved from the second stage 27 onto the transport path 28. Receive the goods.
In addition, in the case of illustration, the conveyance path 28 has two belt conveyors arranged in series on the front and rear, but is not limited.
Further, a left traveling body 29 and a right traveling body 30 that reciprocate in the left and right directions by the traveling means C are provided between the portion directly above the large liquid crystal panel A carried to the front end side of the transport path 28 and the left and right directions. The left traveling body 29 and the right traveling body 30 are moved up and down by the action of, for example, the cylinder 31 as the lifting means C, and lowered to the lower surface having a suction hole (not shown) to be a large panel on the conveying path 28. A third stage 32 for sucking and holding the upper surface of A is provided.
Further, a payout path 33 for receiving the large panel A of the third stage 32 lowered by the extension action of the cylinder 31 on the upper surface is provided immediately below the third stage 32 stopped at a position away from the transport path 28.
A belt conveyor is used for the payout path 33 and heads for processing (for example, the method of Utility Model Registration No. 3195489) for subdividing the product size of the next processing.
Further, on both sides of the conveyance path 28, just below the traveling path of the left traveling body 29 and the right traveling body 30, on the lower surface of the lower substrate 2 of the large panel A sucked and held on the lower surface of the third stage 32, A second cutter 34 for scribing a cutting line 35 for cutting is provided on a line that coincides with the cutting lines 3, 4.
The second cutter 34 detects the position of the base 22 and the scribe position by the camera (mounted) in the same manner as the first cutter 19. The position adjustment after detection and the configuration of each part are the same as those of the first cutter 19. Therefore, detailed description is omitted.
As the traveling means C, the sliders of the traveling body 6, the first traveling body 12, the second traveling body 15, the third traveling body 24, the left traveling body 29, and the right traveling body 30 are movably engaged with the rail 36. The linear motor provided on the rail 36 and each slider is used for traveling. However, the present invention is not limited to this. For example, a ball screw that is reversibly rotated by a servo motor can be driven to the holding female screw.
Moreover, although the cylinders 8, 17, 25, and 31 are used as the lifting means, the invention is not limited, and for example, a ball screw screwed into a holding female screw can be driven by a servo motor.
If comprised as mentioned above, as shown to the right figure from the left figure of the process action | operation figure of FIG. 1, by entering the large panel A on the bed B, a new enters the cutting line 4 with the break bar 10, Next, after receiving the first stage 16, the second stage 27 is moved onto the transport path 28, and then immediately before the third stage 32 is received and discharged to the discharge path 33 by the second cutter 34. A cutting line 35 is scribed on the lower surface of the lower substrate 2 of the large panel A so as to match the cutting lines 3, 4.
Then, when it is divided from the payout path 33 into the next process panel, it becomes a panel with one side terminal portion X.
Further, as shown in the process action diagram of FIG. 2 from the left to the right, by supplying the large panel A on the bed B, the break line 10 enters the cutting line 18 and then the first stage 16 receives the load. On the upper surface of the upper substrate 1 of the large panel A, the cutting line 4 parallel to the cutting line 18 is scribed by the first cutter 19.
Thereafter, as in FIG. 1, it is transferred to the conveyance path 27 and immediately before being discharged to the discharge path 33 received by the third stage 32, the cutting line 35 is scribed on the lower substrate 2 of the large panel A by the second cutter 34. Therefore, a split with a two-sided terminal is obtained in accordance with the separation of the end material between the terminal portion X and the above-described cutting lines 4 and 18 in accordance with the division of the split panel for the next processing.
