Notebook computer keyboard substrate and processing technique thereof

Abstract

The invention relates to the technical field of keyboard fittings of notebook computers, in particular to a notebook computer keyboard substrate and a processing technique thereof. The keyboard substrate is peripherally vertically bent upward to enclose a containing recess, and the recess wall of the containing recess is provided with bent portions. Since the recess wall of the containing recess is provided with the bent portions, the cross section of the recess wall of the containing recess faces horizontally and is avoided from being directly exposed outside, no coating is needed to be coated on the cross section of the recess wall of the containing recess, processing is facilitated, product yield is improved, and integral appearance of a keyboard is more attractive. A metal plate for manufacturing of the keyboard substrate is pre-baked to form a pre-baked board, and the pre-baked board is subjected to stamping molding according to a stamping die, so that processing procures can be reduced, and production efficiency and yield of products can be improved.

Description

technical field [0001] The invention relates to the technical field of keyboard accessories for notebook computers, in particular to a keyboard substrate for notebook computers and its processing technology. Background technique [0002] The keyboard structure of a notebook computer includes a keyboard substrate and keycaps. The middle area of ​​the keyboard substrate is provided with a number of hooks for locking the scissor brackets. slot, and the keycap is installed in the accommodating slot of the keyboard substrate through the cooperation of the scissors bracket and the hook. The keyboard substrate is made of aluminum plate, steel plate or metal alloy plate, and the surface and cut surface of the metal plate will show metallic luster, which not only affects the appearance of the notebook computer, but also interferes with the use of the keyboard. In order to solve this problem, manufacturers of notebook computer accessories usually provide a layer of sprayed coating fo...

AI Technical Summary

Problems solved by technology

After stamping and forming, several hooks are formed in the middle area of ​​the keyboard substrate. At this time, paint or paint is sprayed on the surface of the keyboard substrate. The paint or paint will stay in the gaps of the hooks and solidify, resulting in the keyboard substrate not meeting the production and processing requirements. Its production efficiency and product yield are low

[0004] see figure 1 , figure 2 The cutting surface 22 of the groove wall 21 of the accommodating groove 2 of the existing keyboard substrate 1 faces upwards, and because the thickness of the keyboard substrate 1 is relatively thin, the area of ​​the cutting surface 22 of the groove wall 21 of the accommodating groove 2 is relatively small, so there is no It is convenient for painting process, and the product yield rate is low, and the adhesion of the sprayed layer on the cutting surface 22 is not strong, it is easy to be scraped off or fall off by itself, resulting in the exposed metal sheet, affecting the overall appearance of the keyboard substrate 1, interferes with keyboard use
