Film tearing device and film tearing method thereof

Abstract

The invention discloses a film tearing device and a film tearing method thereof. The device comprises: lifting conveyers, which is used for conveying a workpiece of a film to be torn; a heating platform, which is located between two adjacent lifting conveyers and used for placing and heating the workpiece; a top auxiliary heating component, which is located above the heating platform and used fordirectly heating the protective film on the workpiece; and a film roller, which is located at one end of the heating platform, includes a vacuum pipe (equipped with multiple vacuum suction pipes and extending through the interior of the heating platform), and is used for adsorbing the protective film through the vacuum suction pipes, winding the adsorbed protective film by rolling and integrally peeling off the protective film. By simultaneous heating of the workpiece and vacuum adsorption for film tearing up and down, the above film tearing device can help reduce the bonding performance between the protective film and the workpiece, is beneficial to automatic or semi-automatic peeling of various protective films on the surface of the workpiece, is convenient and fast to operate, has highheating efficiency, achieves the purpose of efficient film tearing, and saves lots of manpower and material costs.

Description

technical field [0001] The invention relates to the field of film tearing technology, in particular to a film tearing device and a film tearing method thereof. Background technique [0002] In the production process of surface mount technology, key equipment such as chip mounters are often used to apply films to the workpieces produced for dust prevention and protection, and the pasted protective films often need to be peeled off or replaced later. For the protective film for temporary protection, due to its weak adhesive performance, the edge can be raised by the existing tape sticking method, and then the protective film can be separated by reel or air knife blowing; but this method is only suitable for the adhesion with the workpiece. Smaller protective film is peeled off. For the case where the protective film and the workpiece are bonded as a whole by organic packaging materials, due to the excellent packaging performance, the protective film is bonded very firmly, and ...

AI Technical Summary

Problems solved by technology

For the protective film for temporary protection, due to its weak adhesive performance, the existing tape can be used to lift the edge, and then the protective film can be separated by reel or air knife blowing; but this method is only suitable for the adhesion with the workpiece. Smaller protective film is peeled off. For the case where the protective film and the workpiece are bonded as a whole by organic packaging materials, due to the excellent packaging performance, the protective film is bonded very firmly. It is difficult to use manual heating to peel off the film. High-efficiency stripping removal may cause damage to the workpiece during the process. If the smooth progress of the entire process is not used, the operation is difficult, time-consuming, labor-intensive, inefficient, and there is a risk of being burned, which is not conducive to the process.
