Automatic film tearing machine and film tearing process thereof

Abstract

The invention discloses an automatic film tearing machine and a film tearing process thereof. The automatic film tearing machine comprises a conveying belt, a lifting and sliding platform, a picking manipulator, an easy-to-tear guide-out mechanism and a film tearing mechanism. The conveying belt is horizontally arranged on a frame; the lifting and sliding platform is arranged at the discharging end of the conveying belt; the picking manipulator is arranged on the other side of the conveying belt and the lifting and sliding platform; the easy-to-tear guide-out mechanism is arranged on one sideof the conveying belt, and the film tearing mechanism is arranged above the lifting and sliding platform and the easy-to-tear guide-out mechanism; the film tearing mechanism comprises a rotating component and two film tearing components, and the film tearing components are respectively arranged on two sides of the rotating component. The automatic film tearing machine and the film tearing processthereof have the advantages that the film tearing difficulty is lowered effectively, and damage to base materials is reduced; alternate feeding and discharging of the base materials are realized, andlinkage between feeding and discharging of the base materials and the film tearing mechanism is effectively improved; the film tearing components are driven synchronously in the same direction to rotationally tear films, and accordingly, the film tearing efficiency is improved greatly.

[0002] A process step that is often involved in the production and manufacturing of mobile phones and other electronic products is "tearing film". Tearing film is to tear off the film on the surface of mobile phone parts before or after assembly for subsequent Other processes, such as the assembly process of the glass screen components outside the camera of a mobile phone, include glass sheets, adhesives, foam and other components. Before the foam is attached to the glass sheet, it needs to be glued to the glass sheet with the help of adhesive After attaching, tear off the film body on the adhesive surface of the glass sheet, and the adhesive layer on the adhesive surface will adhere and fix the foam; in the industry, the tear film currently used for the peeling process of the sheet film The methods include the traditional manual tearing of the film and the film body is torn off after the film body is clamped by the jaws of the manipulator; since the film body is attached to the substrate such as the adhesive, the gap between it and the substrate is small, and the manual method is used to remove the film body. The film tearing method or the mechanical claw tearing film method need to be inserted from the gap between the film body and the substrate during the film tearing process. It is difficult to tear the film, and the substrate is often damaged during the film tearing process, which affects product quality; in addition, the existing film tearing method has poor connection between the film tearing and the base material feeding, and the supply time difference of the base material makes the film tearing mechanism unable to work at full capacity, resulting in the inability to substantially increase the production capacity of the film tearing; in addition, the current Some tearing actions are single-piece film tearing, and only one piece of film can be torn off at a time. The tearing efficiency is low and the cost of tearing the film is high.
