A kind of keycap processing equipment

Abstract

The invention discloses keycap machining equipment. The keycap machining equipment comprises a first rotating roller, a second rotating roller, conveying belts arranged on the first rotating roller and the second rotating roller in a wound manner and a material carrier assembly arranged on the conveying belts. The number of the conveying belts is two sets, the two sets of conveying belts are symmetrically arranged on the first rotating roller and the second rotating roller in the wound manner, a gap is arranged between the two sets of conveying belts, a printing device is arranged above the conveying belts, and a liquid storage case is arranged below the conveying belts. Ultraviolet photocuring protection liquid is contained in the liquid storage case, and a drying box is arranged on one side of the liquid storage case. When keycaps are driven by the material carrier assembly to rotate to the position above the liquid storage case, the keycaps are driven by the material carrier assembly to move downwards. A vibration assembly cooperating with the material carrier assembly is further arranged on one side of the second rotating roller. The ultraviolet photocuring protection liquid issmeared to the keycaps, a protection function is achieved on printing patterns on the keycaps, and printing characters are prevented from being worn.

Description

technical field [0001] The invention belongs to the technical field of keycap processing, and in particular relates to a keycap processing equipment. Background technique [0002] At present, the computer keyboard keycaps print characters on the upper surface of the plastic injection molding. In order to prevent the characters from being worn out, the following methods are usually used to protect the characters: 1. Print a protective layer on the characters. The scope of the protective layer It is slightly larger than the font, within the range of the upper surface of the keycap, but the keyboard produced by this method is not beautiful, and there is a circle of water stains around the font. 2. Increase the printing area of ​​the protective layer to the entire keycap upper surface, but this method is not suitable for keycaps with beveled edges, because this printing method cannot evenly coat the beveled edges of the keycaps. In recent years, in order to improve the quality ...

[0002] At present, the computer keyboard keycaps print characters on the upper surface of the plastic injection molding. In order to prevent the characters from being worn out, the following methods are usually used to protect the characters: 1. Print a protective layer on the characters. The scope of the protective layer It is slightly larger than the font, within the range of the upper surface of the keycap, but the keyboard produced by this method is not beautiful, and there is a circle of water stains around the font

2. Increase the printing area of ​​the protective layer to the entire upper surface of the keycap, but this method is not suitable for keycaps with beveled edges, because this printing method cannot evenly coat the beveled edges of the keycaps

In recent years, in order to improve the quality of keyboards, spraying and in-mold injection technologies have been used to coat the protective layer, but the spraying technology is not environmentally friendly and is rarely used in foreign markets, while the in-mold injection technology requires the use of special equipment and Materials, huge investment, not suitable for the majority of manufacturers
