Problems solved by technology

However, the touch panel with this structure is found to have poor tactile feeling, low hardness, easy wear and deformation, and its touch function is prone to failure after long-term contact.
In addition, the existing touch panel has a flat surface structure, which does not conform to the principles of ergonomics. If you touch it for a long time, your hands will easily feel sore and have a strong sense of fatigue.

Embodiment Construction

[0017] The present invention is described below in conjunction with accompanying drawing.

[0018] as attached figure 1 Shown is a manufacturing process of a curved glass touch panel according to the present invention, which mainly includes the following steps:

[0019] (1) Material selection: select raw material glass A with a thickness of 1.7mm;

[0020] (2) Surface treatment: The raw material glass A is subjected to sandblasting treatment by surface sandblasting process, and the roughness is controlled to 0.2 to obtain glass B;

[0021] (3) Cutting: cut the glass B into multiple square glasses C with the desired appearance size, the size of the square glass C in this embodiment is 121*119mm;

[0022] (4) Milling shape: milling the four corners of the square glass C to be rounded and chamfered to make glass D;

[0023] (5) Hot press molding: hot press glass D into a 360-degree arc surface, the angle of the arc surface is controlled at ±2 degrees, and the height tolerance...

Abstract

The invention discloses a process for making a curved glass touch panel. The process mainly comprises the following steps: (1) selecting materials; (2) carrying out surface treatment; (3) cutting; (4) milling the shape; (5) carrying out hot-press forming, namely hotly pressing glass D into a 360-degree curved surface, controlling the angle of the curved surface to be plus or minus 2 degrees and the height tolerance of a central point to be within plus or minus 0.5 mm, and making curved glass E; (6) tempering; (7) carrying out silk-screen printing; and (8) baking and forming. According to the process, the curved glass touch panel made in the process replaces the conventional flat plastic sheet touch panel, is improved in hardness and wear resistance and is not easy to deform, the structure design meets the man-machine engineering and the finger radian requirements, people do not feel tired after operating the curved glass touch panel for a long time, and meanwhile, the touch panel is also improved in precision and touch performance and is high in reliability.

Description

technical field [0001] The invention relates to a production process of a touch panel, and specifically designs a production process for a touch panel with curved glass in peripheral accessories of a computer. Background technique [0002] At present, the touch panels used in notebooks to control mouse pointing are mostly made of plastic sheets, that is, a protective plastic sheet is attached to the touch electronic circuit board to assemble the touch panel. When our hands move on the touchpad, it can accurately sense the computer screen, move to the desired position, and realize a series of operation functions by clicking and other actions. However, the touch panel with this structure is found to have poor touch feeling and low hardness during use, which is easy to wear and deform, and its touch function is likely to fail after prolonged contact. In addition, the existing touch panel has a flat surface structure, which does not conform to the principles of ergonomics. Touc...
