It has the characteristics of high wiring density, light weight, thin thickness, and good bendability. During the production process of FPC circuit boards, it is necessary to lift the dry film on the product surface. However, the existing film lifting methods are mostly manual operations, resulting in low production efficiency and high labor costs.

[0003] The publication number CN 214757129 U discloses a film lifting device for FPC circuit board dry film, which includes a film lifting head and an FPC circuit board; it also includes multiple groups of adhesive wheels.
