Description

Technical Field

[0001] The utility model relates to the technical field of touch panel processing, in particular to a touch panel etching tool. Background Art

[0002] For the safety of car drivers, more and more car manufacturers require blind touch button technology, and the in-car display screen is generally required to be anti-glare. The traditional method is to first etch 3D buttons on the glass, and then use spraying, immersion and other methods to make an AG layer on the glass surface. The disadvantage of this approach is that it requires a two-step process, which is complicated and has low production efficiency. For this reason, our company has simplified the manufacturing process and only uses one process to achieve 3D buttons and AG effects on the glass at the same time. Specifically, a layer of acid-resistant etching protective film is silk-screened on the function key position on the glass surface, and then the glass is subjected to AG treatment, such as applying etching cream on the surface of the cover plate, and then removing the protective film on the key position after AG, so that the key position can be protruding, while the cover plate with AG effect in other positions can be made. Patent application No. 202222730228.9 discloses an automatic printing mechanism for etching cream on an IT0 glass substrate, including a support box and a placement box fixedly connected to the top of the support box, the top of the placement box is slidably connected to an empty slot box, one side surface of the empty slot box is fixedly connected to a printing box, the front side surface of the inner cavity of the printing box is fixedly connected to a first left and right box, and the rear side surface of the inner cavity of the printing box is fixedly connected to a first left and right box. A first limit box is fixedly connected, a scraper is provided on one side surface of the first limit box, a paste outlet pipe is fixedly connected to the one side surface of the scraper, the liquid inlet end of the paste outlet pipe is fixedly connected to a pump through a hose, a paste storage tank is fixedly connected to one side surface of the pump, a drying box is fixedly connected to one side surface of the empty slot box, a first connecting rod is fixedly connected to the front side surface of the empty slot box, a second left and right box is provided below the first connecting rod, a second connecting rod is fixedly connected to the rear side surface of the empty slot box, and a second limit box is provided below the second connecting rod; in this scheme, although automatic printing and drying of etching paste can be realized, before applying etching paste to the glass plate, a silk-screen printing equipment is needed to silk-screen an acid-resistant protective film on the surface of the glass plate, which increases the processing steps, reduces production efficiency, and is not conducive to assembly line preparation. Therefore, the utility model discloses a touch panel etching tooling to solve the above problems. Utility Model Content
