Abstract

The invention discloses an etching device for a lens protection sheet, which is characterized in that it comprises a rotating base, a telescopic etching mechanism arranged on the rotating base, a lens protection sheet transmission mechanism located above the telescopic etching mechanism, and simultaneously with the rotating A controller (7) connected to the base, the telescopic etching mechanism, and the lens protection sheet transmission mechanism. The invention also discloses an etching method for the lens protection sheet, which includes step 1: adding rough etching solution into the rough etching tank, adding micro etching solution into the micro etching tank, adding clear water into the cleaning tank and the like. In the present invention, the controller controls the lifting and rotation of the etching tank so as to perform rough etching, cleaning, and micro-etching on the lens protection sheet in the etching basket, and has a higher degree of automation. In addition, the invention improves the etching effect of the lens protection sheet by performing rough etching and micro etching on the lens protection sheet.

Description

technical field [0001] The invention relates to the field of lens protection sheet processing, and specifically provides an etching device for lens protection sheets and an etching method based on the device. Background technique [0002] During the production process of the mobile phone lens protection sheet, a ring-shaped texture pattern will be etched on the protection sheet, which makes the mobile phone lens protection sheet more individual. However, the traditional etching method has serious burrs on the edge of the texture pattern during etching, and the etching is uneven. Moreover, the traditional etching method has a low degree of automation and requires a lot of labor costs. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects, provide a lens protection sheet etching device and an etching method based on the device, which can improve the etching effect and have a higher degree of automation. [0004] In...
