Automatic film tearing mechanism based on products for production

Abstract

The invention relates to the technical field of film tearing devices, in particular to a product automatic film tearing mechanism based on production, which comprises a fixed mounting base plate, a special-shaped lifting plate, a side end fixing block and a side edge lifting block, the special-shaped lifting plate is arranged on the front side of the fixed mounting base plate through a downward pressing assembly, and the special-shaped lifting plate is in a vertical Z shape. A product is tightly pressed on the surface of a loading table through the lower end of a bottom mounting block, one end of a protective film is tilted through blowing of a high-pressure nozzle, the tilted end of the protective film can be firmly sucked under the negative pressure action of a vacuum negative-pressure suction nozzle, and the tilted end of the protective film can be clamped to the front side surface of a special-shaped lifting plate through the lower end of a strip-shaped protective film clamping plate; and then the product is driven to move in cooperation with the material carrying table, automatic film tearing can be completed, the problem of adhesive residues caused by adhesive tape tearing can be effectively solved, and the problem of protective film breakage residues caused by high-pressure air tearing is greatly solved.

Description

technical field [0001] The invention relates to the technical field of film tearing devices, in particular to an automatic film tearing mechanism based on production products. Background technique [0002] In the production process of many products, the surface needs to be covered with a protective film, and then the protective film needs to be removed. At present, the commonly used film tearing methods in the industry are tape tearing film or high-pressure air tearing film, but in the FPC industry, customers have certain requirements on the surface of FPC. Requirements, the tape tearing method is easy to introduce residual glue to the surface of the FPC, resulting in poor appearance of the FPC. At the same time, the high-pressure air tearing film method is easy to blow off part of the film, and the protective film has a low adhesion. Strong product, it is easy to tear the protective film in the process of tearing off the protective film, resulting in poor residue of the pro...

Problems solved by technology

[0002] During the production process of many products, the surface needs to be covered with a protective film, and then the protective film needs to be removed. At present, the commonly used tearing methods in the industry are tape tearing or high-pressure air tearing, but in the FPC industry, customers have certain requirements for the FPC surface. Requirements, the tape tearing method is easy to introduce residual glue to the surface of the FPC, resulting in poor appearance of the FPC. At the same time, the high-pressure air tearing method is better for some products that are easy to blow off and the adhesive force of the protective film is small, but for some parts. For strong products, it is easy to tear the protective film during the process of tearing off the protective film, resulting in poor protective film residue on the surface of the product. At the same time, due to factors such as the shape of the protective film and uneven distribution of adhesive force with the product, high-pressure air blows off the protective film. , the tail of the protective film is easily broken
