[0061] The working principle and film tearing process of the present invention are as follows:

[0062] The jig flow channel 100 transports the jig from one side to the other side through the conveyor belt 102. Multiple FPC boards (one-to-one corresponding to the film tearing needles 402 and the film suction blocks 305) are laid flat on the jig and transported with the jig to the film tearing station between the film tearing mechanism 300 and the ejector mechanism 400.

[0063] The pressing cylinder 202 of the upper mold driving mechanism 200 is actuated to drive the film tearing mechanism 300 to descend as a whole, and the positioning pin 504 on the upper mold plate 301 of the mold is inserted into the positioning hole on the fixture for positioning;

[0064] The lifting cylinder 501 of the lower mold driving mechanism 500 is actuated to drive the ejector mechanism 400 to descend as a whole, so that the tearing needle 402 is inserted into the hole on the PSA film and drives the PSA film to move upward, while the FPC board is fixed on the fixture, thereby tearing the PSA film from the FPC board; the PSA film rises to the bottom surface of the film absorbing block 305 under the action of the tearing needle 402, and the air hole 308 of the film absorbing block 305 absorbs and generates negative pressure to absorb the PSA film. At the same time, the pulling block driving cylinder 304 drives the pulling block 303 to move, and the pulling block 303 is separated from the clamping block 306. The clamping block 306 is reset under the action of the torsion spring 307, and the clamping part of the clamping block 306 cooperates with the bottom surface of the film absorbing block 305 to clamp the PSA film;

[0065] The upper die driving mechanism 200 drives the film tearing mechanism 300 to rise to the original position as a whole, and the lower die driving mechanism 500 drives the ejector mechanism 400 to descend to the original position. Then, the block driving cylinder 304 drives the block 303 to move again. The block 303 pushes the clamping block 306 and overcomes the elastic force of the torsion spring 307 to open the clamping block 306. Then, the air hole 308 of the film suction block 305 blows air to blow the PSA film downward into the waste box 403.

[0066] The conveyor belt 102 runs, and the jig is output to one side for unloading operation. According to the above steps, the film tearing operation can be completed continuously, and the film tearing operation can be performed synchronously on multiple FPC boards each time, and the operation efficiency is high.

[0067] In this embodiment, each of the pulling blocks 303 corresponds to a column of film absorbing blocks 305 , and each column of film absorbing blocks 305 has three blocks, for a total of three columns, so that nine FPC boards can be synchronously peeled off at the same time.
