In the assembly process of consumer electronics products, some small-sized, complex-structured and shaped adhesive small parts are mostly adhered to sheet-shaped film materials, and then the sheet-shaped film materials are placed on a tray to achieve the stacking of sheet-shaped film materials. Due to the softness of the sheet-shaped film materials and the adhesiveness of the parts, manually taking the sheet-shaped film materials for loading and unloading products requires a large amount of labor costs, and the work efficiency is relatively low. Manual operation is difficult to accurately position the sheet-shaped film materials, affecting the processing effect.

[0003] In the prior art, the clamping module of the tray and the suction module of the sheet-shaped film material mostly operate independently. Both the clamping module and the suction module need to be equipped with independent linear modules. The suction module sucks the sheet-shaped film material onto the product through a group of linear modules, and the clamping module clamps the tray to an empty bin through another group of linear modules. Obviously, the driving stroke is long, the equipment manufacturing cost is high, and it is not conducive to improving work efficiency. Therefore, it is necessary to provide a feeding mechanism for sheet-shaped film materials with high stability, high production efficiency and accurate loading and unloading.
