Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of paint spraying, in particular to a jig for spraying paint on key caps. Background Art
[0002] At present, in order to mark specific symbols or logos on the surface of products, people usually perform spray painting and laser engraving. Spray painting and laser engraving is a process that uses optical principles for surface treatment. For example, the symbols on the keycaps of computer keyboards are also processed by spray painting and laser engraving. When the keycaps are being sprayed, they are usually fixed on a keycap spray painting jig, and then the keycaps are sprayed with paint. After the painting is completed, the keycaps can be removed and replaced with another batch of keycaps for spray painting.
[0003] The accuracy of the keycap spraying operation will affect the uniformity of the paint on the keycap surface. The existing keycaps are all plastic products. When the paint spraying pressure is too high or the paint spraying angle is incorrect, the keycaps will be damaged, resulting in insufficient paint spraying accuracy. In addition, the paint spraying pressure is relatively high, and the keycaps are not firmly fixed to the fixture of the paint spraying jig, causing the keycaps to fall off or tilt during the paint spraying process, affecting the paint spraying efficiency and increasing the defective rate of production. Moreover, in order to enhance the strength of the previous paint spraying jig, the thickness of the paint spraying jig is often increased, resulting in excessively high production costs. Summary of the invention
[0004] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the utility model is to provide a jig for keycap spraying. The jig for keycap spraying has a simple and novel structure. When spraying the keycap, the keycap is clamped in the keycap fixing seat. When fixing, the connecting shaft of the keycap can be inserted into the limiting hole, and the limiting protrusion arranged on the mounting seat can limit and fix the keycap clamped in the keycap fixing seat. When the keycap is clamped in the keycap fixing seat, the keycap can be clamped and fixed well, so that the keycap is not prone to tilting or falling off during the painting process, ensuring the smooth progress of the painting process, reducing the defective rate of painting, and improving production efficiency. The keycap spraying jig can be reused many times, and can also be used as a carrier to stack the keycaps that have been painted, which can save the mold manufacturing cost. At the same time, the painted keycap can be placed on the irradiation lamp and the light-transmitting hole on the mounting seat can be used to irradiate the letter area of the keycap to confirm whether the hidden keycap letter area is covered.

[0021] The jig for painting the keycaps in the present embodiment has a simple and novel structure. When painting the keycaps, the keycaps are clamped in the keycap fixing seat 2. When fixing, the connecting shaft of the keycaps can be inserted into the limiting hole 21, and the limiting protrusion 31 arranged on the mounting seat 3 can limit and fix the keycaps clamped in the keycap fixing seat 2. When the keycaps are clamped in the keycap fixing seat 2, the keycaps can be clamped and fixed well, so that the keycaps are not prone to tilting or falling off during the painting process, ensuring the smooth progress of the painting process, reducing the defective rate of painting, and improving production efficiency. The keycap painting jig can be reused many times, and can also be used as a carrier to stack the keycaps that have been painted, which can save the mold manufacturing cost. At the same time, the painted keycaps can be placed on the irradiation lamp and the light-transmitting holes 33 arranged on the mounting seat 3 can be used to irradiate the letter area of the keycaps to confirm whether the hidden keycap letter area is covered, which is beneficial to the final finished product rate and light transmittance of the hidden letter keycaps obtained by spraying paint.
[0022] In this embodiment, the edge of the opening of the limiting hole 21 is set as a first inclined surface 22 inclined outward from bottom to top, which is convenient for inserting and fixing the keycap and key shaft; the outer wall of the limiting protrusion 31 is set as a second inclined surface 32 inclined inward from bottom to top, and the second inclined surface 32 can be abutted and fitted with the inner side of the keycap, thereby further improving the stability of the keycap when it is fixed.
[0023] In this embodiment, the keycap fixing seats 2 are arranged in rows on the upper end surface of the main carrier board 1 , and at least one row of paint-through holes 11 is provided between two adjacent rows.
[0024] In this embodiment, the mist paint not attached to the keycap will be sucked away by negative pressure from the paint-through hole 11, and the hole wall of the paint-through hole 11 passes through the upper and lower end surfaces of the main carrier board 1, thereby ensuring that the main carrier board 1 will not be contaminated by the mist paint.
[0025] In this embodiment, the upper end surface of the main carrier plate 1 is provided with a plurality of positioning columns 12, and the positioning columns are respectively located at the corners of the upper end surface of the main carrier plate 1; the lower end surface of the main carrier plate 1 is downwardly provided with a plurality of limiting sleeves 13 and a plurality of supporting columns 14, and the supporting columns 14 are located between two adjacent rows of keycap fixing seats 2, and the limiting sleeves 13 are respectively located at the corners of the lower end surface of the main carrier plate 1; the interior of the limiting sleeves 13 is a sleeve cavity 131 opening upward, and the positioning columns 12 can be sleeved in the sleeve cavity 131; the lower end surface of the main carrier plate 1 is provided with a plurality of reinforcing ribs 15 distributed in a matrix shape, which can increase the connection strength between the keycap fixing seat 2 and the main carrier plate 1, avoid breakage or deformation during use, further improve the practicality of the keycap spraying jig, and extend its service life.
[0026] In this embodiment, the support column 14 and the limiting sleeve 13 arranged on the lower end surface of the main carrier board 1 are conducive to supporting the upper and lower layers when the jig is stacked as a whole after the painting is completed, so as to avoid the contact between the upper and lower layers of the keycaps during the painting process, which affects the quality of the keycaps finally obtained. Specifically, during stacking, the support column 14 of the upper main carrier board 1 abuts against the upper surface of the lower main carrier board 1, and the positioning column 12 on the upper surface of the lower main carrier board 1 is sleeved in the limiting sleeve 13 of the upper main carrier board 1.
[0027] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
