Film tearing device of encapsulating machine and film tearing method thereof

Abstract

The invention provides a film tearing device of an encapsulating machine and a film tearing method thereof. A covering film feeding device of the encapsulating machine comprises a film tearing platform used for placing a covering film with release paper, a feeding assembly used for moving the covering film, a film tearing manipulator and a clamp used for pressing the covering film with the releasepaper, wherein a vacuum film rolling platform used for fixing the covering film with the release paper is arranged on the left side of the film tearing platform; the feeding assembly is used for transferring the covering film which is not torn to the film tearing platform; and the film tearing manipulator is arranged on the upper side of the film tearing platform, the lower end of the film tearing manipulator is fixedly connected with a pressing platform, and the film tearing manipulator can drive the pressing platform to reciprocate up and down. According to the film tearing device of the encapsulating machine and the film tearing method thereof, manual film tearing is replaced by full-automatic film tearing, so that the production efficiency and the film pasting precision are improved,and the labor cost is saved; and meanwhile, the production of covering films of various different types can be considered, a large number of tool clamps do not need to be manufactured, and a large amount of clamp cost is saved.

Description

technical field [0001] The invention relates to the technical field of film tearing devices, in particular to a film tearing device of an encapsulating machine and a film tearing 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] In the prior art, manual tearing of the covering film is currently used in the FPC production process, which is unstable in efficiency and lamination accuracy. At the same time, it is necessary to make a large number of fixtures to assist in tearing the film.

[0004] At the same time, the number of rolls of the existing film tearing device may increase for some highly viscous cover films, resulting in a decrease in the efficiency of tearing the film
