Description

Technical Field

[0001] The utility model relates to the technical field of spraying machines, in particular to a keyboard bottom plate spraying machine. Background Art

[0002] Common keyboard base materials include plastic, metal, etc. The keyboard base is one of the components of the keyboard, usually located at the bottom of the keyboard. It is used to support and fix the various components of the keyboard, as well as the lines connecting the keyboard to the computer host. The material and design of the keyboard base have an important impact on the stability and service life of the keyboard.

[0003] The keyboard coating process refers to spraying or coating the keyboard surface. Among them, primer treatment is to apply primer to the keyboard surface to improve the adhesion and durability of subsequent coatings. The keyboard base spraying is to improve the keyboard's aesthetics, wear resistance, corrosion resistance and other properties.

[0004] The prior art patent document with publication number CN210935538U provides a keyboard base plate spraying machine, which can detect the position of the keyboard base plate on the belt conveyor through the sonar locator. When the keyboard base plate reaches between the two L-shaped clamps, the servo motor rotates forward to drive the bidirectional screw column to rotate. The rotation of the bidirectional screw column can push the two L-shaped clamps to move closer to each other along the rectangular through hole 2, thereby clamping and spraying the keyboard base plate. After the spraying is completed, the servo motor reverses and the two L-shaped clamps move away to make the keyboard base plate fall on the belt conveyor and be transmitted out, forming an assembly line mode and improving work efficiency.

[0005] In the above-mentioned prior art, although the sprayer moves closer to each other along the second rectangular through hole through two L-shaped clamps to clamp and spray the keyboard base plate, the sprayer in the patented technology can only spray one side of the keyboard base plate when clamping and fixing the keyboard for spraying. After spraying, the other side needs to be replaced for spraying. It is impossible to spray both sides of the keyboard base plate at the same time, which reduces the spraying efficiency of the keyboard base plate. Therefore, we need a keyboard base plate sprayer.
