During pad pasting packing, complex film 7 is placed in feed bin 61, material loading drive module 63 drives material loading adsorption module 62 and moves to corresponding feed opening 611, then material loading adsorption module 62 starts in order to adsorb a complex film 7, then material loading drive module 63 drives material loading adsorption module 62 and moves to conveying mechanism 1 top, material loading adsorption module 62 removes the adsorption to complex film 7, then can place complex film 7 on conveying mechanism 1, and then conveying mechanism 1 carries complex film 7 to dyestripping station and tectorial membrane station. By adopting the structure, the automatic feeding of the composite film can be realized, and the film sticking efficiency is further improved.

Further, the bin 61 is obliquely arranged, and the feed opening 611 is arranged at the bottom surface of the bin 61 facing the conveying mechanism 1, and the edge of the composite film 7 is located on the bottom surface when the composite film 7 is placed in the bin 61. The vertical form of complex film 7 is placed in feed bin 61, in order to make the complex film 7 be in the bottom of feed bin 61, in order to improve absorbent success rate, make feed bin 61 be certain angle setting, specific angle can be for being 10-30 with conveying mechanism 1, feed opening 611 sets up in the bottom surface of feed bin 61 towards conveying mechanism 1, the edge of complex film 7 is located the bottom surface when the complex film 7 is arranged in feed bin 61. Specifically, the bottom surface of the cartridge 61 may be opened, and the aforementioned bottom surface may be formed by providing stoppers or baffles 612 at opposite ends to block the composite film 7. The distance between two baffles 612 is slightly less than the width of the composite film 7, so that the composite film 7 in the storage bin 61 cannot drop when the loading adsorption module 62 is turned over. Certainly, the distance between the two baffles 612 should not be too small, and after the loading adsorption module 62 adsorbs one composite film 7, the two ends of the composite film 7 can slightly deform and then move together with the loading adsorption module 62 to separate from the storage bin 61 as a reference.

In one embodiment, the loading drive module 63 includes a loading motor 631, an eccentric assembly 631, and a linkage assembly 633. The output of material loading motor 631 is connected with eccentric wheel component 631's input, and eccentric wheel component 631's output is connected with link assembly 633's input, and link assembly 633's output is connected with material loading adsorption module 62, and material loading motor 631 drive material loading adsorption module 62 overturns to seal feed opening 611 or orientation and be on a parallel with conveying mechanism 1. Fig. 6-8 show three states of the loading adsorption module 62 closing the feed opening 611, the loading adsorption module 62 turning over, and the loading adsorption module 62 turning over to face and be parallel to the vacuum adsorption belt, respectively. Connect the output of material loading motor 631 and the input of link assembly 633 through eccentric wheel assembly 631 for the axis of rotation of link assembly 633 input and the axis of rotation of material loading motor 631 output are misaligned, and through the transmission of link assembly 633, convert the moment of torsion of material loading motor 631 output into the upset of material loading adsorption module 62 finally. The turning angle of the feeding adsorption module 62 can be set according to the requirement, such as 290-295 degrees, and preferably 293 degrees. For reference to the prior art, the structure and the matching relationship of the eccentric wheel assembly 631 and the connecting rod assembly 633 are not described herein again. During the packing, complex film 7 is placed in feed bin 61, if place or the manipulator is placed through the manual work, after compound film 7 is adsorbed to material loading absorption module 62, material loading motor 631 rotates, drives eccentric wheel assembly 631 and rotates, and link assembly 633 who is connected with eccentric wheel assembly 631 drives material loading absorption module 62 upset, and then material loading absorption module 62 closes the negative pressure, places compound film 7 on the vacuum adsorption belt.

In other embodiments, the feeding mechanism 6 may also adopt a manipulator, or may also adopt manual feeding directly without the feeding mechanism 6.
