Membrane paper separation device

Abstract

The invention discloses a membrane paper separation device. The device comprises a machine table; a bearing plate which is arranged on the machine table in a sliding mode and used for bearing the covering membrane product, wherein notches are formed in the corners of the bearing plate; an adhesive substrate which fills in the notches and is used for supporting and adhering the corners of the release paper, wherein the adhesive substrate can rotate relative to the machine table to be separated from the corners of the release paper, and the adhesive substrate can move in the length direction ofthe bearing plate to be separated from the notches; a vacuum suction plate which is located above the bearing plate, can ascend and descend relative to the bearing plate and is used for sucking the cover membrane product with the rolled corners of the cover membrane; and a roller sticking mechanism which is arranged on the vacuum suction plate and used for sticking and rolling the corners of the covering membrane so that the corners of the covering membrane are rolled up and separated from the release paper. The device is ingenious in structure, the corners of the covering membrane can be stably rolled up so that the covering membrane can be conveniently separated from the release paper, the flatness of the covering membrane can be recovered, and convenience is provided for subsequently adhering the covering membrane to a corresponding product.

Description

technical field [0001] The invention relates to the technical field of film covering equipment, in particular to a film paper separation device. Background technique [0002] FPC, or flexible circuit board, is a printed circuit board made of flexible insulating substrates. With the development of science and technology, flexible circuit boards have been used more and more widely, but at the same time, the characteristics of flexible circuit boards have also brought about related issues such as how to assemble circuit boards and how to mount them. At the same time, flexible circuit boards are used in the process of Oxidation will occur, and a protective film needs to be attached to it to prevent oxidation. [0003] For the existing cover film, in order to facilitate the production and protection of the product, a layer of release paper is pasted on the bottom of the cover film. The cover film with the release paper is the cover film product. In the FPC production process, th...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned automation equipment for separating the release paper on the cover film mainly has the following defects: First: the cover film product is processed by the original factory, and it is difficult to ensure the processing accuracy of the equipment, resulting in the cover film and the cover film in each cover film product. The adhesion between the release papers is inconsistent. When the adhesion between the cover film and the release paper is very strong, the sticky roller cannot roll up the corners of the cover film, but the entire cover film product (cover film with release type) paper) together, resulting in the failure of the separation of the cover film and the release paper; second: after the above-mentioned equipment removes the release paper adhered to the cover film, it does not consider restoring the initial flatness of the cover film, resulting in There are wrinkles and corners in the cover film, which affect the subsequent application of the cover film
