Embodiment Construction

[0017] A kind of UV paint spraying process for TV front shell surface described in the present invention is described below:

[0018] 1. First understand the basic composition of UV paint components can be summarized as:

[0019] 1>, active diluent

[0020] 2>, oligomers

[0021] 3>, photoinitiator

[0022] 4>, additives

[0023] 2. UV workshop and its equipment requirements:

[0024] The production site is required to be a dust-free workshop, and its UV varnish line supporting equipment: dust removal equipment, spray booth, UV conveyor line, UV curing furnace, purification isolation room, UV lamp, purification air supply system, and electrical control system.

[0025] 3. UV paint spraying process:

[0026] Loading→electrostatic dust removal→UV oil spraying→UV paint leveling→UV curing→UV sweeping treatment→off-line finished product inspection, the specific operation process is as follows:

[0027] The operator needs to check whether the incoming material is defective in ...

Abstract

The invention relates to a television shell surface UV (ultraviolet) paint spraying technique which comprises the following steps: baiting, electrostatic dust collection, UV oil spraying, UV paint leveling, UV curing, UV photoscanning, and finished product inspection. The concrete operation process comprises the following steps: sanding defective products at a baiting worktable by the operating personnel, and carrying out electrostatic dust collection; sweeping the shell surface, carrying out dust collection again, and sending into a spray chamber; reciprocating scanning in the shell spraying region by a spray gun; after spraying paint on the shell, carrying leveling treatment through a transmission line; after finishing the leveling, carrying out UV irradiation curing by a UV lamp; after finishing UV curing, carrying out electrostatic air blast cooling; and warehousing. The television shell surface UV paint spraying technique can effectively solve the problems of discoloration and color difference in the television shell, enhance the production efficiency, lower the application cost, reduce the environmental pollution and the like.

Description

technical field [0001] The invention relates to the field of televisions, in particular to a UV paint spraying process on the surface of the front shell of the television. Background technique [0002] As we all know, when the functions of TVs on the market are mature, the requirements for the appearance of TVs are getting higher and higher, and they need to be full of individual characteristics, especially the quality of spraying the color of the front shell of the TV. Traditional spraying has low efficiency, high cost, pollutes the environment, and affects the health of construction workers. Contents of the invention [0003] In order to solve the low efficiency and high cost of traditional spraying, pollute the environment, and affect the health of construction workers. The company introduced all kinds of equipment in the UV coating production line and put them into production. Compared with the traditional spraying process technology, the spraying process technology o...
