Description

technical field [0001] The invention relates to an automobile touch screen test device, more specifically, the invention relates to a special fixture for automobile touch screen friction durability test used for precise positioning and clamping of the automobile touch screen. Background technique [0002] Nowadays, the input devices of electronic devices are basically keyboards and touch screens, and touch screens have become the input devices of many high-end electronic devices due to their advantages of durability, fast response, space saving, and easy human-computer communication. Especially in the automotive industry, it is gradually replacing traditional buttons and becoming the main channel for intelligent vehicles to communicate with people. [0003] The touch screen is a multi-layer composite film, which is made of a layer of glass or plexiglass as the base layer. The surface of the base layer is covered by a transparent conductive layer and a layer of hardened, smoo...

AI Technical Summary

Problems solved by technology

The clamping force of the welding clamp is too large, it is easy to damage the touch screen, and the positioning accuracy is poor, the versatility is poor, and it is impossible to position and clamp different types of touch screens; the positioning plate combined positioning and clamping can solve the positioning accuracy and clamping to a certain extent. , but the structure is too single to be universally applicable to various types of touch screens
