The detailed description and drawings of the Ming are believed to have an in-depth and specific understanding of the purpose, features, and characteristics of the present invention. However, the drawings are provided for reference only and are not intended to limit the present invention. First, please refer to FIG. 2, which is a perspective view of an embodiment of a machine for transferring LCD screen glass according to the present invention. The present invention uses a transfer machine table ⑽ to transfer the color filter and the large glass 1 which have not been cut or polished, and the transfer machine table 20 uses a microcomputer to automatically control the transfer of the large glass. At the time, the transfer machine 20 is provided with a transfer claw platform 30, and FIG. 3 is a bottom perspective view of the transfer claw platform. Four gripper structures 31 are provided at the four corners of the α-hailer transfer claw platform 30. Each gripper structure 31 is provided with an L claw 32 for supporting the four corners of the large glass i. The grasping claw structure 31 is provided on both sides of the large glass 1, so in this embodiment, two rod claws 33 are provided at the center of the other two sides of the large glass to fix the large glass 1 to the correct position. The large glass 1 does not shake during the transfer process. A l-claw movable structure 34 is provided at the center of the side-shifting claw platform 30, as shown in Fig. 4 is a schematic plan view of the bottom of the transfer claw platform, and Fig. 5 is a schematic plan view of the top view of Fig. 4, Figure 5 shows the movement state of the L-claw movable structure, and please also refer to Figure 3. The L-claw movable structure 34 is two discs 341, 341 fixedly connected by a center, four linkage levers 342, and one motion. Composed of a valve 343, one end of the four linkage rod 342 is movably connected to the periphery of the: = disc 341 and is asymmetrically connected to each other, and the other end is movably connected to the four gripper structures 31 and the two branches. The claw 33, and the movement, 343 is linked to another disc 341. In this book, the COSCO movable valve 3 4 3 is a pneumatic valve, as shown in Figure 5, when 590994

When the large glass 1 is to be gripped, the movable valve 343 is extended to drive the disc 341 to rotate an angle clockwise, and the other disc 341 is also rotated synchronously, as shown in FIG. The structure 31 and the two rod claws 33 are clamped inward, so that the four L claws 32 and the two rod claws 33 can hold the large glass 1. Conversely, if the large glass 1 is to be released, the movable valve 343 is retracted to drive the disc 3 41 ′ to rotate an angle counterclockwise, then the four claws 3 2 and the two lever claws 3 3 release the large glass 1 . In the actual operation, when the four L claws 32 and the two lever claws 33 grip the large glass 1, its 1 claw and the large glass! Between the edges, a gap of about 0.5 mm is reserved for the micro-movement of the four claws 32. Please refer to FIG. 6, which is an enlarged perspective view of the gripper structure in FIG. 3. The principle of the present invention that the large glass 1 will not be broken when grasping the large glass 1 is that the large glass 1 is grasped by using the transfer claw platform 30 to raise each L claw to a certain point one by one. The water damage between the large glass 1 and the machine can not maintain surface tension or affinity, and then raise the transfer claw platform to an appropriate transfer height, while raising, adjust the height of each L claw in small amounts' Keeping the large glass 1 in a non-horizontal state allows the water on the large glass 1 to flow off from the lower side to reduce the water load. Referring again to FIG. 3, this embodiment uses a servo motor 35 and a threaded rod 36 to control the upward and downward movement of the transfer claw platform 30. The claw structure 31 is linked to the claw structure 31 by a high and low valve 311. On the L-claw 32, the high-low valve 311 is a pneumatic valve, and the four L-claws are sequentially raised or lowered in order to increase the size of the middle L-claw. The micro-size must not be too large to prevent the large glass 1 from breaking. The best place can be between 5 and 3, so that the large glass 1 is in a non-horizontal state until the transfer claw platform 30 liters reach a suitable height. 0
