Problems solved by technology

The existing keycaps are usually made of ABS plastic injection molding. During the cooling molding process, due to the release of internal stress, the keycaps are deformed, which will cause the edges of the keycaps to be curved, which greatly reduces the quality and yield of the keycaps.

Abstract

The invention relates to a keycap processing technology. The keycap processing technology includes the following steps that firstly, ABS plastic is processed into a tablet pumping material, and the table pumping material is processed into a keycap core body through the injection molding technology; secondly, a carbon fiber layer wraps the keycap core body to form a keycap body, heating and pressurization are conducted on the keycap body, and then cooling and depressurization are conducted; thirdly, multiple arc-shaped grooves are formed in the edge of the keycap body processed in the second step at intervals, wherein the diameter of the arc-shaped grooves is 0.1-0.5 mm; and fourthly, the keycap body processed in the third step is baked and then cooled, radium engraving is conducted so that a character can be formed in the surface of the keycap body, and a keycap finished product is obtained. When a keycap is produced through the technology, the product quality and yield are effectively improved.

Description

technical field [0001] The invention relates to a key cap processing technology. Background technique [0002] A keyboard is an extremely important input device for an electronic device (such as a computer or a mobile phone), and keys are the main components of the keyboard. The keycap is located on the top of the key, which is the interface for the keyboard touch work. The existing keycaps are usually made of ABS plastic injection molding. During the cooling molding process, due to the release of internal stress, the keycaps are deformed, which will cause the edges of the keycaps to be curved, which greatly reduces the quality and yield of the keycaps. . Contents of the invention [0003] In view of this, the object of the present invention is to provide a keycap processing technology capable of improving product quality and yield. [0004] In order to achieve the above object, the keycap processing technology of the present invention comprises the following steps: ...
