Full-automatic film tearing machine

Abstract

The invention discloses a full-automatic film tearing machine which comprises a support, a conveying mechanism, a film lifting mechanism, a conductive rubber covered roller mechanism, a collection board and a comb-shaped film separation mechanism. The conveying mechanism is used for conveying a PCB with film protective films bonded to the two faces; the film lifting mechanism is installed on the support, used for lifting the edges of the film protective films and provided with a first gap where the PCB penetrates; the conductive rubber covered roller mechanism is pivoted to the support, used for bonding and winding the film protective films, located behind the film lifting mechanism in the conveying direction of the PCB and provided with a second gap where the PCB penetrates; the collection board is used for stacking and collecting the film protective films and fixed to the portion, between the conductive rubber covered roller mechanism and the film lifting mechanism, of the support; and the comb-shaped film separation mechanism is installed on the collection board, used for separating the film protective films wound around the conductive rubber covered roller mechanism and located between the collection board and the conductive rubber covered roller mechanism. By the adoption of the full-automatic film tearing machine, the film protective films on the two faces of the PCB can be automatically torn away, the torn-away film protective films can be stably stacked and collected in order layer by layer, and the film tear-away success rate is increased.

Description

technical field [0001] The invention relates to a fully automatic film tearing machine. Background technique [0002] In the PCB industry, after the surface treatment of the PCB board, film protection film on the surface, and exposure, the film protection film on both sides of the PCB board needs to be torn off before entering the development and washing equipment. [0003] At present, there is no equipment for tearing off the film protective film in the PCB industry. The ordinary film tearing machine can tear off the film protective film in principle, but due to the lack of adaptability, the organization has not designed for tearing the film protective film from the PCB board. The success rate of directly tearing the film is low, and the product scrap is high, so it has not been applied. Therefore, at present, the tearing work of the film protective film is still done by traditional hands, but the manual tearing efficiency is low, the labor cost is high, and the quality is...

Problems solved by technology

[0003] At present, there is no equipment for tearing off the film protective film in the PCB industry. The ordinary film tearing machine can tear off the film protective film in principle, but due to the lack of adaptability, the organization has not designed for tearing the film protective film from the PCB board. The success rate of directly tearing the film is low, and the product scrap is high, so it has not been applied

Therefore, at present, the tearing work of the film protective film is still done by traditional hands, but the manual tearing efficiency is low, the labor cost is high, and the quality is difficult to guarantee.

[0004] Moreover, the tearing action of the tearing film mechanism of the existing common film tearing machine is easy to tear the film protection film, which makes it difficult to collect the torn film protection film, and after the film protection film is torn off, the film protection film is still sticky. Attached to the tearing film mechanism, resulting in confusion in the collection of the torn film protective film, and even the possibility of a post tearing film mechanism, which further reduces the success rate of tearing the film
