FPC (FILM PRINTED CIRCUIT, flexible circuit board), referred to as soft board, is a highly reliable and excellent flexible printed circuit made of polyimide or polyester film as the base material. , An indispensable important carrier or key connection means for aerospace, military, automotive, and consumer electronics products. Since the FPC substrate is relatively soft, it is necessary to locally increase the strength of the material in some important parts, which is usually achieved by attaching a reinforcing sheet. With the development of electronic products towards light, thin, small, and compact, the precision of FPC and the complexity of the manufacturing process are increasing, and more stringent requirements are placed on the quality of FPC. In order to ensure product quality, it is necessary to fully automate the bonding of the reinforcement board on the FPC during production.

In the field of automation of the production process, the automation of material supply is an important part. Through the practice of FPC production, FPC manufacturers and equipment suppliers have jointly found that after forming the reinforcing plate and sticking it on the slightly sticky tape to make roll material, it is most suitable for the automatic supply of equipment among various input methods. material.

Before pasting the reinforcement board, it is necessary to peel off the reinforcement board from the slightly adhesive tape, suck it away by the bonding head and then paste it on the FPC. There are many types of reinforcement materials, such as PI, FR4, PSA, steel sheet and aluminum sheet. With the different FPC products, the shape and size of the reinforcement board are also very different. Most of the existing peeling mechanisms continue to use the peeling mechanisms of ordinary labeling machines. Disadvantages of this method: poor reliability, easy flying and stacking of materials, making the bonding head fail to absorb the reinforcing plate, especially for small-sized reinforcing plates, the success rate is extremely low, which seriously affects the production efficiency of the whole machine. The generality of the process is poor, and it cannot be applied to large dimensional changes of the reinforcing plate; the adjustment of the mechanism is difficult, which seriously affects the efficiency of batch switching of FPC products.

The stripping knife 12 is connected with the base 11 through the guide rail, and the first limiting block 13 , the differential head 14 , the first quick-change joint 15 and the second limiting block 16 are all fixed on the stripping knife 12 . The differential head 14 is mainly used to precisely adjust the position between the stripping knife 12 and the base 11, so that after the reinforcing plate is peeled off, it coincides with the center of the suction position of the laminating head to improve the suction success rate. The first limit block 13 and the second limit block 16 are mainly used to ensure that the material roll is fed in, and the forward direction of the roll position will not deviate, resulting in material suction failure. Wherein, the second limiting block 16 can move within a certain range to adapt to different strip widths. The inside of the stripping knife is processed with an air path, and the first quick-change joint 15 leads the vacuum to the internal air path, so that the material roll and the stripping knife 12 are closely attached together before stripping, and the effect of stripping the reinforcing plate is improved.
