Production process of novel high-precision ultra-thin key

Abstract

The invention provides a production process of a high-precision ultra-thin key, which comprises the steps of: producing a silica gel sheet, a plastic key, a shading sheet and double-sided glue; installing the plastic key into a rig hole according to an identification sequence number on the back of the plastic key, and tightly pressing the plastic key to be flat by using a mold; sheathing the shading sheet with the black front face facing downwards into the rig, and carrying out positioning by taking the peripheral retaining wall of the rig as standard; sheathing the silica gel sheet with a contact facing downwards on the rig of an upper cover and then continually and automatically printing UV glue on the top surface of the silica gel sheet for two to three times; and after tightly pressing a pressing rig on a punching machine for one time and ejecting out a key device by a base put on an ejection rig, sticking the double-sided glue on the key device.

Description

technical field [0001] The invention relates to the field of communication equipment spare parts, in particular to a production process of a high-precision ultra-thin key (IMF). Background technique [0002] Mobile phones, computer keyboards, etc. have been used for a long time. The common problem is that the surface is polished and the graphics and characters on the surface become blurred. IMD is an in-mold decoration technology, also known as coating-free technology, which is currently a popular surface decoration technology in the world, with surface hardening transparent film, middle printing pattern layer, and back injection molding layer. In the middle of the ink, it can prevent the surface of the product from being scratched and rubbed, and can keep the color bright and not easy to fade for a long time. The general process is to apply printing on the surface of the film, high pressure forming, punching, and finally combine with plastic to form. IMD can be divided in...

AI Technical Summary

Problems solved by technology

[0002] The common problem that mobile phones, computer keyboards, etc. have been used for a long time is that the surface will be scratched and the graphic characters on the surface will become blurred.

However, there are still material technology bottlenecks (such as the inverse relationship between hardness and stretch, positioning accuracy, distance between irregular shapes and bumps, die slope, etc.
