  By the way, according to the cleaving method of Patent Document 1, since the first traveling table and the second traveling table are provided side by side, a large installation area is required. Since the liquid crystal panel is transferred from the first traveling table to the second traveling table and from the second traveling table to the first traveling table, the cleaving device is significantly increased in size and the equipment cost is significantly increased. The cost increases due to the problem that the operation rate of the apparatus is significantly reduced due to the trouble of transferring the liquid crystal panel from one side of the panel to the other side table.

  Accordingly, the present invention is to provide a cleaving device for a liquid crystal panel that solves the various problems described above.

  In order to solve the above-described problems, the present invention receives a large liquid crystal panel having a horizontal orientation that has been input, and includes a supply stage having alignment means and a carry-in means for feeding forward after alignment, and the supply stage A scribe stage having a conveying means for receiving the liquid crystal panel carried forward and a holding means for delivering the liquid and a holding means after receiving the cargo, and a right and left of the scribe stage. A first horizontal bar member provided so as to be able to travel straight and intermittently along the edge, and a plurality of X-axis direction cutting lines parallel to the first A bar of the liquid crystal panel on the first horizontal bar member A first cutter provided for scribing, a second cutter provided for scribing a cutting line in the Y-axis direction, and the scribing A first carry-out conveyor provided so as to receive the liquid crystal panel delivered by the transfer means in front of the first conveyor, a second carry-out conveyor provided in front of the first carry-out conveyor, the first carry-out conveyor and the second A first advancing / retreating body provided so as to travel forward at a speed equal to the discharge speed of the conveying means by the forward traveling means and directly return by the backward traveling means immediately above the end facing the carry-out conveyor; A first auxiliary table provided on the advancing / retreating body so that the entire upper surface of the payout end of the liquid crystal panel is sucked and held when lifting is stopped by the lifting / lowering means; A constant speed synchronization mechanism provided so that the second carry-out conveyor travels forward at a constant speed, and a first traveling forward and backward across the lower B surface of the liquid crystal panel below the first auxiliary table. A traveling body is provided, and a third cutter provided on the first traveling body to scribe a cutting line on the B surface of the liquid crystal panel and a cutting line scribed by the first cutter on the A surface of the liquid crystal panel are broken. And a folding device provided to break the cutting line scribed by the third cutter on the side B of the liquid crystal panel stopped just above the second carry-out conveyor. And a third carry-out conveyor provided so as to receive and receive a load from a transfer machine that sucks and holds the large liquid crystal panel in front of the second carry-out conveyor and then turns 90 degrees, and the third carry-out conveyor A discharge conveyor provided in the front; a second advance / retreat travel body having the same conditions as the first advance / retreat travel body provided immediately above the opposite ends of the third carry-out conveyor and the discharge conveyor; A second auxiliary table under the same conditions as the first auxiliary table, an equivalent speed synchronizing mechanism, a reverse traveling means for returning the second forward / backward traveling body, and a lower side of the large liquid crystal panel below the second auxiliary table. A fourth cutter provided with a second traveling body that travels back and forth across the side B surface, and a fourth cutter provided on the second traveling body so as to scribe a cutting line on the B surface of the large liquid crystal panel, and the large liquid crystal panel A second folding roller provided to break the cutting line scribed by the second cutter on the A-side of the A and the B-side of the B-side of the large liquid crystal panel stopped just above the payout conveyor A configuration comprising a folding device provided to break a cutting line scribed by four cutters is adopted.

  As described above, according to the liquid crystal panel cleaving apparatus of the present invention, the cutting line in the X-axis direction is formed on the upper surface A of the large liquid crystal panel carried into the scribe stage by the first cutter of the first horizontal bar material. The cutting line in the Y-axis direction is scribed by two cutters, and the scribing cutting line scribed by the first cutter by the folding roller that travels at the stop when the scribed large-sized liquid crystal panel is delivered to the first carry-out conveyor at a predetermined pitch. A cutting line is scribed on the lower surface B of the large liquid crystal panel by the third cutter that breaks and runs.

  At this time, the first auxiliary table holds the entire length of the upper A-side processed portion of the large liquid crystal panel by suction, so that it is extremely stable break (because the liquid crystal panel is prevented from being lifted by the pressing of the folding roller). Also, the scribe depth is made uniform and stable.

  Then, when the cutting line scribed by the third cutter reaches directly under the folding device, it breaks and can be sequentially divided from a large liquid crystal panel to a large liquid crystal panel.

  And after picking up this divided large liquid crystal panel by the transfer machine, after changing the direction by turning 90 degrees and receiving the load on the second carry-out conveyor, it is carried out at a predetermined pitch to the front discharge conveyor, At the time of stopping, the cutting line scribed by the second cutter is broken by the second folding roller in the same manner as described above, and the cutting line is scribed on the B surface of the large liquid crystal panel by the fourth cutter.

  At this time, since the upper A surface processed portion of the large liquid crystal panel is sucked and held by the auxiliary table in the same manner as described above, extremely stable break and scribe can be similarly performed.

  After that, when the cutting line scribed by the fourth cutter reaches just below the splitting device of the payout conveyor, it breaks and can be sequentially divided from the large liquid crystal panel to the small liquid crystal panel of the product size.

  For this reason, in addition to being able to perform the work of dividing a large liquid crystal panel into a small liquid crystal panel of a product size on one line extremely efficiently, the installation area is reduced because of one line, Thus, it is not necessary to turn the liquid crystal panel upside down (inversion), which is troublesome and causes a significant reduction in efficiency.

  When the auxiliary table travels forward by the forward travel means, the carry-out conveyor and the auxiliary table are driven at a constant speed by the constant speed synchronization mechanism, so that reliable delivery and unloading can be performed, and suction by the reverse travel means. Since the release auxiliary table is returned to the original position, the tact feed of the liquid crystal panel or the large liquid crystal panel can be performed quickly and smoothly.

  Embodiments of the present invention will be described with reference to the accompanying drawings.

  In the embodiment of the present invention, as shown in FIG. 1 to FIG. 5, A is a supply stage for receiving a large liquid crystal panel P in a horizontal orientation, and the supply stage A has an alignment of the received liquid crystal panel P. Means B and carry-in means C for supplying the aligned liquid crystal panel P forward are provided.

  For example, as shown in FIG. 6, the liquid crystal panel P is loaded by a double-row pin 2 (shown in FIG. 6) in which the lower surface of the liquid crystal panel P introduced by the robot R or the like is lifted by the extension action of the cylinder 1. After that, the pin 2 is lowered by the contraction action of the cylinder 1 and received on the table 3 (shown in FIG. 7).

  Thereafter, while the air pumped into the hollow table 3 as the alignment means B is ejected from the numerous small holes 4 on the top wall of the table 3, the liquid crystal panel P on the table 3 is floated as shown in FIG. Under the floating condition, the both side edges of the liquid crystal panel P are sandwiched and aligned as shown in FIG.

Thereafter, while stopping the ejection of air, the liquid crystal panel P aligned on the belt conveyor 8 is received while the belt conveyor 8 serving as the loading means C on both sides of the table 3 is raised by the extension action of the cylinder 7.
In addition, the cylinder 6 is contracted after receiving the load, and the pushing member 5 is separated.

  Thereafter, the liquid crystal panel P is supplied forward by the running of the belt conveyor 8, but the present invention is not limited thereto, and alignment and supply may be performed by other methods.

  As is well known, the liquid crystal panel P is configured by bonding two glass substrates of a thin film transistor on the A surface (upper side in the drawing) and a color filter on the B surface (lower side in the drawing).

  D is a scribe stage that receives and processes the liquid crystal panel P carried in by the carrying-in means C.

  The scribe stage D is constituted by a belt conveyor 9 in which an aligned liquid crystal panel P carried by the belt conveyor 8 is transferred to the upper surface and transferred to a fixed position on the belt conveyor 9 (by a stopper or the like). The stop position is determined) The liquid crystal panel P is held by the holding means E, and the movement of the liquid crystal panel P when the cutting line is scribed is stopped.

  In the case shown in the drawing, the holding means E sucks the inside of the intake / exhaust box 10 having the intake window 11 on the upper surface disposed on the lower side of the belt conveyor 9 so that the belt on the belt conveyor 9 is sucked. At the same time, the liquid crystal panel P is adsorbed and held on the belt from the numerous small holes 12 provided in the belt.

  In addition, a horizontal bar member 13 is provided that crosses immediately above the scribe stage D, and the bar member 13 is caused to travel straight in the front-rear direction by the traveling means F and intermittently travel by numerical control in the front-rear direction.
