A high-speed laser etching device for pet thin film

Abstract

The invention discloses a high-speed laser etching device used for a PET film and relates to the technical field of laser etching. The high-speed laser etching device comprises an operation plate andan etching assembly, wherein the etching assembly is arranged above the operation plate. A driving assembly used for moving the etching assembly is arranged below the operation plate. A PET film etching plate is arranged on the side face of the operation plate. The high-speed laser etching device has the beneficial effects that the high-speed laser etching device is used for conducting etching ona PET film, the film etching speed is increased, in addition, the etching depth can be controlled, the etching depth is more uniform, in addition, mechanical medicines do not need to be used for cleaning the surface of the film in laser etching, the environment is prevented from being polluted by the chemical medicines, and the product qualification rate is increased. Due to the fact that rotationof a motor and stretching and contracting of an electric push rod are controlled, traditional manual etching is replaced, film etching is more accurate, the etching accuracy is improved, the PET filmetching quality is improved, and the machining efficiency for film etching is improved.

Description

technical field [0001] The invention relates to the technical field of laser etching, in particular to a high-speed laser etching device for PET films. Background technique [0002] PET film is a kind of film with conductive function. The conductive film needs to be laser etched in the process of processing. The surface resistance of the conductive film after laser etching is relatively uniform, and the light transmittance and thermal stability are good. However, the current Some laser etching devices have the following problems: [0003] 1. The etching depth of traditional wet etching is shallow, and it is often necessary to etch the PET film multiple times. It is difficult to grasp the etching depth after multiple etchings, which will cause uneven etching and low pass rate of products, and the traditional The wet engraving needs to be cleaned with chemicals, causing pollution to the environment; [0004] 2. The existing PET film needs to be etched manually. In the proces...

[0004] 2. The existing PET film needs to be etched manually. In the process of etching, due to the factors of large manual operation errors, the PET film will be displaced due to the influence of external force, which will affect the accuracy of etching and make it The process of PET film etching cannot meet the processing requirements in production, which reduces the etching quality of PET film and also affects the processing efficiency of PET film etching;
