Description

Technical Field

[0001] The utility model relates to the field of material transfer mechanisms, in particular to a suction and translation material transfer mechanism and an automatic film tearing device. Background Art

[0002] Flexible Printed Circuit (FPC), also known as soft circuit board, flexible circuit board, is favored for its excellent characteristics such as light weight, thin thickness, free bending and folding. With the rapid development of the electronics industry, circuit board design is becoming more and more high-precision and high-density, and the development of the FPC industry has become an inevitable trend. In the FPC flexible circuit board industry, a layer of FPC protective film needs to be covered on the FPC. The main functions of the protective film are: 1. Protect the copper foil from being exposed to the air to avoid oxidation of the copper foil; 2. Cover for subsequent surface treatment; 3. In subsequent SMT, it plays a solder mask role. During the transportation and protection process of the FPC protective film, the film is covered with a layer of base paper, which needs to be separated before using the protective film.

[0003] Traditional equipment basically peels off the backing paper from the roll, cuts it into single sheets, and then sticks it on the copper foil. However, most domestic FPC manufacturers are relatively small in scale, and the number of single products produced daily is relatively small (tens to hundreds of sheets). Using roll film will cause cost waste, so these factories prefer to use single-sheet, punched protective film, tear the film manually and then stick it on the copper foil. However, manual work has the problems of low labor efficiency and high production cost.

[0004] There is an urgent need to develop a device that can automatically tear off the film. Before automatic film tearing, the FPC workpiece needs to be loaded. The traditional loading mechanism generally sucks the FPC workpiece through a vacuum suction cup. Since the FPC workpiece is relatively soft, even if multiple vacuum suction cups are set to suck the FPC workpiece at the same time, the FPC workpiece will undergo certain bending and deformation. If the bent FPC workpiece is directly placed in the film tearing mechanism, the film tearing may fail or the FPC workpiece may be damaged during the film tearing process. Utility Model Content
