Description

Panel cutting device {PANEL BREAKING SYSTEM}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting device for cutting a large liquid crystal panel (for example, formed by bonding a TFT panel and a CF panel) to a desired size.

While importing a large liquid crystal panel, a method of efficiently cutting sequentially on one line in a desired size (for example, from a large portion to a small portion) while carrying in is known (see, for example, Patent Document 1). ).

Japanese Patent Laid-Open No. 2010-26267

However, according to the method of Patent Literature 1, the front edge cutting material (cutting part of the front edge part of the panel), rear edge cutting material (cutting part of the rear edge part of the panel) and the intermediate cutting material (cutting part) generated by cutting. The cut portion of the middle portion of the panel is dropped from the cut position (for example, in a chute) to be discarded.

However, when the cutting member falls from the cutting support bar member in accordance with the end of the cutting, the cutting member slides inclined due to the weight relationship. Therefore, the cutting edge of the cutting member faces upwards, and the cutting edge facing upwards is lower than the lower edge of the upper panel. It comes in contact with the terminal surface, and then falls while sliding while contacting.

This causes scratches on the terminal surface and causes defective products.

In addition, when the panel is transported by transporting the panel by transporting it to the downstream conveyor after cutting, the terminal surface is contacted by the tail side surface of the belt constituting the conveyor. do.

Therefore, in the present invention, a cutting device is provided such that the cutting edge material is recovered by cutting the cutting edge material so that the cutting edge material is not generated in the end face, and stored in the downstream conveyor without damaging the terminal surface. Is to provide.

MEANS TO SOLVE THE PROBLEM In order to solve the said subject, this invention is an upstream carry-in path provided so that the large liquid crystal panel formed by the joining of two sheets can be carried in, and the said liquid crystal in front of this carry-in path. Left and right are synchronized by the first traveling means on the lower side of the export route provided for storing and carrying out the cut liquid crystal panel cut | disconnected the panel, and the left and right sides between this carry-in route and an export route. A traveling body provided to move forward and backward in the front and rear directions, and an upstream slider provided to slide forward and backward by guides on the front and rear ends of the left and right traveling bodies. And a downstream slider and an action provided to slide the upstream slider and the downstream slider, respectively. A center support member provided so as to project upwardly from a center between a stage and both ends of the traveling body, and an upstream support member provided so as to protrude upward from the upstream slider and the downstream slider.

In addition to the transverse diameter, the upper surface of the upper surface of the liquid crystal panel installed so as to move in the front and rear direction by the traveling means, and the upper surface of the liquid crystal panel installed to reciprocate between the two ends of the upper horizontal member and to be elevated by the elevating function ( a first cutter of scribe use, a lower horizontal member provided to traverse the liquid crystal panel on the front lower side of the carry-in path and move in the front-rear direction by a traveling means; A second cutter for scribing the lower surface of the liquid crystal panel, which is reciprocated between both ends of the lower horizontal member and lifted by the lifting function, and in the front-rear direction between the upstream and downstream transport passages. Adopt a configuration consisting of a cutting support bar installed to move and move up and down All.

Moreover, the structure which can adjust the position to the said upper horizontal material, and mounts the 3rd cutter of the scribe for the small part of the upper surface of the liquid crystal panel which raises and lowers by the lifting function is employ | adopted.

In addition, the upstream cutting bar and the downstream cutting bar are moved up and down by lifting means, and as the ascending, the upstream cutting bar and the downstream cutting bar adopt a configuration in which a holding pawl is inserted into the edge of the liquid crystal panel. .

In addition, a pressurizing cutting plate is provided on the lower side of the upstream cutting bar and the downstream cutting bar to raise and lower through the lifting means, and a through hole is formed in the pressurizing cutting plate. do.

According to the cutting device of the present invention as described above, the cutting line of shear edge cutting is scribed by the first cutter on the upper surface of the A surface of the liquid crystal panel by supplying and carrying a large liquid crystal panel into the carrying path, and then the downstream cutting bar. And after the support bar is lowered to suck the upper surface of the A surface of the liquid crystal panel, the cut line is scribed by the second cutter at the front end of the lower surface of the B surface of the liquid crystal panel.

Then, the cutting edge of the liquid crystal panel rises by pressing the cut support bar that moves to the lower surface of the B surface of the liquid crystal panel and presses the raised cutting bar to raise the support bar. Since the downstream cutting bar slides in the downstream direction, the cut front edge cutting material is pulled out and there is no contact with the terminal surface by the pulled front edge cutting material, so that the terminal surface is not damaged. Cause of occurrence can be eliminated.

Of course, the cutting edge of the cutting edge is dropped and discarded because the suction by the downstream cutting bar is released.

Since the cutting edge of the front edge of the liquid crystal panel is sucked up by the support bar and floated, the liquid crystal panel is stored in the transport path by running the traveling body downstream by the first driving means while maintaining this situation. Let's do it.

In this movement, since there is no contact between the receiving end of the carry-out path and the terminal surface formed by cutting due to the suction injuries, it is possible to eliminate damage to the terminal surface, that is, eliminate the cause of defective products.

The same effect occurs when the liquid crystal panel is large.

Also, in the cutting of the rear edge of the liquid crystal panel, the above-described process is performed by the supporting bar and the upstream cutting bar, so that no damage is caused to the terminal surface formed by the cutting.

Further, since the third cutter is provided side by side with the first cutter on the horizontal member, a small cut line may be scribed on the large liquid crystal panel.

In addition, the upstream cutting bar and the downstream cutting bar are raised and lowered by lifting means, and the upstream cutting bar and the downstream cutting bar are provided with a holding cutting pole for inserting the edges of the liquid crystal panel in the upstream cutting bar and the downstream cutting bar. By inserting the side edges by the pawls, cutting of the side edges can be made very smooth.

In addition, a pressure cutting plate for elevating through the lifting means is provided on the lower surface side of the upstream cutting bar and the downstream cutting bar, and the edge of the liquid crystal panel is sucked to the lower surface of the pressure cutting plate by the through hole of the pressure cutting plate. It can be cut by lowering the upstream cutting bar and the downstream cutting bar, and the cut end material can be disposed of in the correct position by releasing suction after moving the upstream cutting bar and the downstream cutting bar together with the traveling body.

The upstream cutting bar 14, the supporting bar 15, and the downstream cutting bar 16 use square pipes whose both ends are closed, and the intake and exhaust holes 17 are formed in the horizontal bottom wall. In order to improve the adsorption property of the intake / exhaust hole 17 of (), it was set as the suction board (of bellows type).

A hose capable of switching the intake and exhaust air is connected to a cylinder 18 communicating with the inside of the upstream cutting bar 14, the support bar 15, and the downstream cutting bar 16.

As the elevating means 13, a system consisting of a ball screw driven by the reversible operation of the motor, a nut for screwing the ball screw, and the like are used.

Moreover, the horizontal member 19 which crosses the carrying-in path 1 is arrange | positioned above the middle of the carrying-in path 1, and the both ends of this horizontal member 19 run through the traveling means 20 in the front-back direction. The traveling body 21 is supported.

The traveling body 21 slides with the rails 4 as a guide, and employs a linear motor system as the traveling means 20. However, the traveling body 21 may be a bolt or a nut system.

A slider 24 reciprocating by the traveling means 23 is provided on the rail 22 provided in the horizontal member 19, and a cylinder 25 is attached to the slider 24. The first cutter 26 which raises and lowers and puts the cutting line X for a large part or an edge is provided.

Moreover, between the carrying-in path 1 and the carrying-out path 2, the cutting support bar which moves back and forth by the moving means 27, and raises and lowers by the lifting means 28. (29) is installed.

In the case shown in the figure, the cut support bars 29 are two parallel pieces before and after the upstream cut bar 14 and the downstream cut bar 16, and the cut support bars are parallel in this manner. Although the cut end material was collected by integrally inserting the chute 30 between (29), it is not limited to this, but it cuts into the lower surface of B surface of liquid crystal panel A when cutting. It is good to contact.

The moving means 27 comprises a rail 31 and a traveling cart 33 having a slider 32 coupled to slide the rail 31, and moving in the front-rear direction. Although the linear motor is used, it is not limited to this, but may be a bolt reversibly driven by the motor, and a nut screwed to the bolt and supported by the travel cart 33.

The elevating means 28 connects the cylinder supported by the chute 30 to the cutting support bar 29, but is not limited thereto.

Further, in front of the upstream cutting bar 14, as shown in Fig. 6, a scribe cutting edge Y for an edge or a large portion between both edges of the lower surface of the B surface of the liquid crystal panel A is scribed. Two cutters 34 are provided.

The second cutter 34 arranges the traveling body 35 on a line crossing the lower side of the liquid crystal panel A, and moves the slider 37 of the lower surface of the traveling body 35 to the rail 36. While engaging to slide, the traveling body 35 is reciprocated by the traveling means 38 of the linear motor, and slides on the rail 40 in the longitudinal direction of the pillar member 39 which is mounted on the traveling body 35. (41) are engaged, and the slider 41 is raised by the action of the cylinder 42, and the second cutter 34 provided on the upper end of the slider 41 contacts the bottom surface of the B surface of the liquid crystal panel A. It is supposed to be.

When comprised as mentioned above, the large liquid crystal panel A is supplied to the carrying-in path 1, and it carries in, and the front side of both edges of the liquid crystal panel A is carried out by the camera P of the both ends of the horizontal material 19, and is carried in. The mark of the edge corner is read, and the scribe line is positioned by sliding the traveling body 21 back and forth by the traveling means 20 so that the horizontal member 19 coincides on the scribe line.

Thereafter, the first cutter 26 is lowered by the action of the cylinder 25 and the slider 24 is driven by the traveling means 23 while cutting lines X are formed on the upper surface of the A surface of the liquid crystal panel A. FIG. Scribe).

Subsequently, when the liquid crystal panel A sent out by the carrying-in path 1 is stopped, the 2nd cutter 34 is raised by the action of the cylinder 42, and also by the action of the traveling means 38. The slider 37 is driven to scribe the cutting line Y on the lower surface of the B surface of the liquid crystal panel A. FIG.

At this time, as shown in FIG. 7, the traveling body 3 is moved by the 1st traveling means B so that the support bar 15 may be located directly on the line which scribes the cutting line Y, and also raises and lowers. Since the support bar 15 and the downstream cutting bar 16 are lowered by the action of the means 13 and the lower surface is in contact with the upper surface of the A surface of the liquid crystal panel A, the liquid crystal panel A at the time of scribe is Do not injure.

After the scribing, the second cutter 34 is lowered by the action of the cylinder 42, and then the liquid crystal panel A, which has been scribed, is sent out to the brake position by the loading path 1.

At this time, since the support bar 15 and the downstream cutting bar 16 are sucked in, the liquid crystal panel A is sucked to the lower surface of the support bar 15 and the downstream cutting bar 16 by the intake and exhaust holes 17. And the liquid crystal panel A, which is driven and supported by the traveling body 3 in the downstream direction by the first traveling means B, is conveyed to the brake position.

The conveyance moves the travel cart 33 in the upstream direction by the moving means 27, and stops the cutting support bar 29 at the position where the cutting line Y has passed upstream, as shown in FIG. I'm making it.

In this way, by lowering only the downstream cutting bar 16 by the action of the lifting means 13, the cutting lines X and Y are cut as shown in FIG.

The cutting edge C of the front edge of the liquid crystal panel A according to the cutting is lowered as it is sucked by the lower surface of the downstream cutting bar 16, thereby releasing suction by the intake and exhaust holes 17 to pressurize air. The cutting material C with which suction was released falls to the chute 30 and is discarded.

On the other hand, while maintaining the suction of the upper side of the cut side end of the liquid crystal panel A on the lower surface of the support bar 15, the downstream cutting bar 16 is raised by the action of the elevating means 13, and then the elevating means 13 functions. As shown in FIG. 9, by raising the support bar 15, the cutting edge side of the liquid crystal panel A is lifted up, and the traveling body (B) is driven by the first traveling means B while maintaining the lifting. The liquid crystal panel A is accommodated in the carrying out path 2 by running 3) downstream.

At this time, as shown in FIG. 10, the terminal surface T formed by the cutting of the liquid crystal panel A is lifted while being sucked by the support bar 15, and changed into the carrying-out path 2. As a result of the burning, there is no contact between the terminal end T and the transfer end of the carry-out path 2 at all, thereby preventing the terminal surface T from being damaged.

After the grinding, suction by the support bar 15 is released, and the upper surface of the A surface of the liquid crystal panel A is lower than the lower surface of the support bar 15 by the pressure of air to the intake and exhaust holes 17. Viii)

In the middle of the liquid crystal panel A, the cutting line X is scribed on the upper surface of the A surface by the first cutter 26, and the second cutter 34 is disposed on the lower surface of the B surface. The cutting line Y is scribed, and the portions of the cutting lines X and Y are cut into the supporting bar 15, the downstream cutting bar 16, and the cutting support bar 29 as shown in FIG. Cut by the action of.

And as shown in FIG. 13, the terminal side of liquid crystal panel A also scribes the cutting line X on the upper surface of A surface by the 1st cutter 26, and the 2nd cutter 34 on the lower surface of B surface. As a result, the cutting line Y is scribed, the upstream cutting bar 14 sucks the end material C, releases the suction, and drops it to the chute 30.

Of course, the cut edge of the liquid crystal panel A is also scribed by the second cutter 34, the scribed portion is cut to form the terminal surface T, and the formed terminal surface T to the carrying path 2 is formed. The changeover is also made by the above action.

The large liquid crystal panel a cut to a large size is stored in the carrying out path 2 and taken out.

Moreover, even when it is necessary to form the terminal surface T in the terminal (on the lower surface of the B surface) opposite to the carrying out path 2 of the large liquid crystal panel a (not shown in the figure), the cutting support bar (29) After the cutting by the upstream cutting bar 14 and the support bar 15, the support bar 15 sucks and floats the terminal side of the liquid crystal panel a of a large part, and then lifts it in (the 1) The upstream cutting bar 14 is slid to the carrying-in path 1 side by the side effector 9, and the cutting material C sucked up by the upstream cutting bar 14 is taken out from the lower side of the terminal surface T. As a result, the cut to the terminal surface T is prevented from occurring by the cut material C, and then, the suction by the upstream cutting bar 14 is released, and the cut material C is discarded in the chute 30.

In the second embodiment of the present invention, as shown in Figs. 3 and 4, the horizontal member 19 can be adjusted in position, and a small cut line Z is formed on the upper surface of the A surface of the liquid crystal panel A. A third cutter 51 for scribing is provided.
