Cover film feeding device of encapsulating machine and separation method thereof

Abstract

The invention provides a cover film feeding device of an encapsulating machine and a separation method of the cover film feeding device. The cover film feeding device of the encapsulating machine comprises a material placing platform used for placing a cover film and a material taking assembly, the lower side of the material placing platform is fixedly connected with a lifting mechanism used for driving the material placing platform to move up and down, the lifting mechanism comprises a carrying plate, and a plurality of fixing plates are fixedly connected to the carrying plate. According to the cover film feeding device of the encapsulating machine and the separation method of the cover film feeding device, the situation that a mechanical arm possibly grabs a plurality of stacked cover films at a time due to the influence of vacuum and static electricity when the cover films are stacked can be prevented through arrangement of a brush; and meanwhile, the cover film feeding device is provided with a stroke adjusting sliding block, the purpose of controlling the size of the cover film can be achieved through movement of the stroke adjusting sliding block in a limiting groove, a photoelectric sensor can send a material shortage signal to external equipment after the cover film is used out, and therefore a user can feed materials in time, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of a covering film feeding device, in particular to a covering film feeding device of an encapsulating machine and a separation method thereof. Background technique [0002] Flexible printed circuit (FPC), also known as flexible printed circuit, flexible circuit board, is favored for its light weight, thin thickness, free bending and folding and other excellent characteristics, but the domestic quality inspection of FPC is still mainly Relying on manual visual inspection is costly and inefficient. With the rapid development of the electronics industry, the design of circuit boards tends to be more and more high-precision and high-density. The traditional manual inspection methods can no longer meet the production needs. The automatic detection of FPC defects has become an inevitable trend of industrial development.

Problems solved by technology

[0002] Flexible printed circuit (FPC), also known as flexible printed circuit, flexible circuit board, is popular for its light weight, thin thickness, free bending and folding and other excellent characteristics, but the quality inspection of FPC in China is still mainly Relying on manual visual inspection, high cost and low efficiency

With the rapid development of the electronics industry, the design of circuit boards is becoming more and more high-precision and high-density. Traditional manual inspection methods can no longer meet production needs. FPC defect automatic inspection has become an inevitable trend of industrial development.

[0003] Usually, the cover film retrieving device is unattended, which will cause the reclaiming device to stop feeding after carrying the manually added cover film, and the user cannot find that the cover film has been used up in time. In the prior art In the use of the FPC cover film encapsulation machine, the cover film is usually stacked together by manual picking and placing of the film. However, due to the influence of vacuum and static electricity when the cover film is stacked, the manipulator may grab multiple stacked covers at one time. film, which will affect the subsequent normal processing of the cover film, and at the same time, the existing automatic film pick-and-place is inefficient
