In one embodiment, the liquid crystal panel split fixture further includes two sliding rods 510 , 512 , two springs 520 , 522 , two connecting rods 530 , 532 , and a pressing rod 540 . The above-mentioned sliding rods, springs and connecting rods are symmetrically arranged, and the pressing rod 540 is connected to the two connecting rods 530 and 532 . These configurations will be described in detail below.

The sliding rods 510 , 512 are respectively located outside the brackets 210 , 220 and fixed on the base 100 . In one embodiment, the sliding rods 510 , 512 are substantially cylindrical, and have threads at their lower ends to lock onto the base 100 .

The springs 520 , 522 are sheathed on the sliding rods 510 , 512 respectively, and the lower ends of the springs 520 , 522 are in contact with the base 100 . The inner diameters of the springs 520, 522 are larger than the outer diameters of the sliding rods 510, 512, so that the sliding rods 510, 512 pass through the springs 520, 522 respectively.

In another preferred embodiment, the depth of the openings 534, 536 may be slightly greater than the height of the compressed springs 520, 522, so as to fully accommodate the springs 520, 522 when the springs 520, 522 are fully compressed. Therefore, the connecting rods 530 , 532 can move up and down along the sliding rods 510 , 512 . Two ends of the positioning member 400 are respectively connected to upper ends of the connecting rod 530 and the connecting rod 532 , so the positioning member 400 can also move up and down between the brackets 210 , 220 along with the connecting rods 530 , 532 .

The compression rod 540 straddles the brackets 210 , 220 and is connected to the connecting rod 530 and the connecting rod 532 . In one embodiment, the pressing rod 540 is substantially in the shape of a "ㄇ", the middle part straddles the brackets 210, 220 and the receiving box 110, and the two ends are respectively fixed on the upper ends of the connecting rods 530, 532. The connecting rods 530 , 532 are sleeved on the sliding rods 510 , 512 respectively. When a pressure is exerted on the pressing rod 540 , the lower connecting rods 530 , 532 and the positioning member 400 will be moved downward together. After the depressing force is released, the connecting rods 530 , 532 and the positioning member 400 return to their original positions due to the elastic tension of the springs 520 , 522 . The main function of the pressing rod 540 is to provide a force-receiving part for the connecting rods 530, 532 and the positioning member 400 to move downward.

The following will describe in detail the operation method of the liquid crystal panel cracking fixture using an embodiment of the present invention.

As shown in FIG. 2A , firstly, a liquid crystal panel is provided. The liquid crystal panel has a cut line 620 , and the cut line 620 separates the liquid crystal panel into a surplus part 610 and a product part 630 . At the same time, a liquid crystal panel cracking jig as mentioned above is provided.

Next, as shown in FIG. 3 , the remaining material portion 610 of the liquid crystal panel is put into the slit d1. It should be noted that the width of the slit d1 is not more than 0.5 millimeter (mm) larger than the thickness of the liquid crystal panel.

Then, the remaining material portion 610 of the liquid crystal panel is pressed against the positioning member 400 so that the outer edge of the split member 320 is roughly located below the cutting line 620 of the liquid crystal panel.

After that, press down the product part 630 of the liquid crystal panel, as shown by the arrow E in FIG. 3 . When the product portion 630 of the liquid crystal panel is pressed down, the liquid crystal panel will rotate slightly around the top surface 322 of the split member 320, especially around the outer edge of the top surface 322. At this time, the remaining material portion 610 moves upward slightly to bear against the bottom surface of the resisting member 310 . When the downward force continues to increase, the bottom surface of the abutting member 310 will become a fulcrum (supporting surface), and the top surface 322 of the split member 320 will become a force bearing point (force bearing surface). The amount of pressing force E will split the liquid crystal panel along the cutting line 620 , thus separating the leftover part 610 from the product part 630 .

Next, referring to FIG. 4 , the product part 630 of the liquid crystal panel is taken out from the slit d1 , and the product part 630 of the liquid crystal panel is separated from the split tool. At this time, the separated residual material part 610 may fall naturally due to gravity, and fall into the material receiving box 110 below. Alternatively, the remaining material portion 610 may not fall down naturally, but is held together by the positioning member 400 , the resisting member 310 and the split member 320 . In the example where the leftover part 610 does not fall naturally, the following steps can be continued.

Referring to FIG. 5 , continue to apply an external force F to press down the pressing rod 540 and move the connecting rods 530 , 532 and the positioning member 400 downward. At this time, the connecting rods 530 , 532 and the positioning member 400 move away from the resisting member 310 and move toward the base 100 . The springs 520, 522 are contracted and deformed by the downward pressure of the connecting rods 530, 532. Because the locating piece 400 moves downward, the previous state where the locating piece 400, the abutting piece 310 and the split piece 320 jointly clamp the remaining material portion 610 is removed, and the remaining material portion 610 is separated from the locating piece 400, the abutting piece 310 and the split piece 320. The splinters 320 fall down into the receiving box 110 .

Afterwards, the external force F is removed to release the depressed state of the pressing rod 540 . At this time, the connecting rods 530 , 532 and the positioning member 400 are moved upward by the elastic restoring force of the springs 520 , 522 , away from the base 100 and close to the abutting member 310 to return to their original positions.

In the prior art, after the liquid crystal panel is cut by a knife wheel, the cut panels are not completely separated from each other, but need to be split manually to separate the remaining material of the liquid crystal panel from the product part. During the splitting process, due to the uneven force applied by hand, it may happen that the splitting is not neatly separated along the cutting line. In more serious cases, fragmentation may occur.

It can be seen from the above-mentioned one embodiment of the present invention that the splitting jig of the liquid crystal panel utilizes the slit formed between the resisting member and the splitting member to perform splitting. The top surface of the split member is used as the stress point (forced plane), and the bottom surface of the resisting member is used as the fulcrum (supported plane), so that the liquid crystal panel can be evenly stressed. During the splitting process, the remaining part of the liquid crystal panel can be smoothly separated from the product part of the liquid crystal panel along the cutting line, so as to improve the possible shortcomings of the prior art and improve the yield of production.

Although the present invention has been disclosed above in terms of implementation, it is not intended to limit the present invention. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, The scope of protection of the present invention should be determined by the contents defined in the claims.
