Machining method for TV set shell pattern

Abstract

The invention discloses a machining method for a TV set shell pattern. The machining method for the TV set shell pattern includes the following steps that the surface of a TV set shell blank body prepared in advance is subjected to preliminary cleaning; the TV set shell blank body after being cleaned is ground and polished so that a preliminary TV set shell can be obtained; the surface of the preliminary TV set shell after being ground and polished is subjected to secondary cleaning; the preliminary TV set shell after secondary cleaning is subjected to abrasive blasting or wire drawing so thata TV set shell can be obtained; primer is sprayed on the surface of the TV set shell; the TV set shell subjected to primer spraying is placed in a drying chamber to be subjected to preliminary dryingso that a primer layer can be formed by the primer; and the surface of the primer layer of the TV set shell is subjected to laser carving so that the pattern needed by a user can be formed. The machining method has the beneficial effects that the production efficiency is substantially improved, remarkable economic benefits are achieved, a pattern layer can be firmly attached to the surface of theTV set shell, and the pattern on the TV set shell is clear, attractive, free of breakage, long in service life and not prone to fall off.

Description

technical field [0001] The invention relates to the field of pattern processing of a television casing, in particular to a method for processing a pattern of a television casing. Background technique [0002] The TV shell can protect the core and picture tube and other components in the TV. Since there is current passing through the TV, it will absorb dust, so the shell can play a certain role in isolating dust; the TV shell is generally made of insulating materials. It can protect people from being injured by high-voltage electricity in the TV. The TV casings in the prior art are made of plastic products or other metal materials (such as aluminum alloy), but plastics usually have poor flame retardancy, and are prone to fires in the event of accidents, thereby causing serious loss of life and property. Moreover, the source of raw materials of some plastic products in the prior art is not environmentally friendly, and some toxic and harmful substances are often volatilized...

AI Technical Summary

Problems solved by technology

The TV casings in the prior art are made of plastic products or other metal materials (such as aluminum alloy), but plastics usually have poor flame retardancy, and are prone to fires in the event of accidents, resulting in serious loss of life and property

Moreover, the source of raw materials of some plastic products in the prior art is not environmentally friendly, and some toxic and harmful substances are often volatilized. Most of the existing TV casing pattern processing adopts spray paint, which is prone to wrinkles when sprayed, and when dried The volatilization of the solvent tends to shrink and cause cracking and shrinkage. It is more likely to cause pinholes and other problems due to the residual air bubbles generated during spraying. Especially for TV casings with complex surface structures, the primer sprayed on the surface is usually difficult to remove. Stays smooth and flat when dry

Water transfer printing is carried out on the primer with the above disadvantages, and the pattern layer is not easy to be damaged and incomplete due to water transfer printing. At the same time, the product is easy to fall off and crack after leaving the factory, and the service life is short.
