Problems solved by technology

[0003] The TV backplane needs to conduct electricity in some specific areas, but the VCM film-coated board is completely non-conductive after coating. Set riveting studs in the position, this method will lead to complex structure of the TV backplane, and the production process is very cumbersome, which reduces the production efficiency

Embodiment 1

[0022] This embodiment proposes a method for laminating a television backplane, comprising the following steps:

[0023] Step 1: Select the steel with steel quality requirements of DX53D+Z and above, and the surface requirements of FB grade and above quality standards as the substrate;

[0024] Step 2: Pretreat the substrate, including degreasing, brushing and rinsing. Degreasing, brushing and rinsing are all carried out at 55°C. Degreasing and scrubbing are carried out with lye with a concentration of 2%, and a flow production line is used for rinsing. , the production line speed is controlled at 60m / min;

[0025] Step 3: Trim the pretreated substrate, including testing the flatness of the substrate and grinding the edge of the substrate. When the flatness is tested, the qualified range of the flatness of the substrate is 0-0.6mm. When it exceeds the range of 0-0.6mm, it is necessary to continue to level the substrate until the flatness of the substrate meets the requirement...

Abstract

The invention discloses a film coating method for a television backboard. The film coating method comprises the following steps: selecting a substrate, and degreasing, brushing and rinsing the substrate; detecting the flatness of the substrate and polishing the edge of the substrate; coating the substrate with glue and conducting film coating; pasting an isolation film on the surface of a film coating layer, marking a conductive area according to the position of a conductive area on the television backboard, and performing laser operation on the marked conductive area position by using laser equipment, and removing film cloth at the marked position on the film coating layer by using laser. With the method, the quality of the film coating layer of the television backboard can be stably guaranteed; by degreasing, brushing, rinsing and finishing the substrate, the bonding force between the film coating layer and the substrate can be ensured to be stable, so film coating quality is improved; and the film coating layer at the marked position is removed by marking the position of the conductive area through a laser technology, so the conductive area can be processed, and the structure ofthe television backboard cannot be complicated.

Description

technical field [0001] The invention relates to the technical field of television manufacturing, in particular to a film coating method for a television backplane. Background technique [0002] With the progress of the society and the development of the economy, the TV has become an indispensable household appliance, and the structural design requirements of the TV are becoming more and more strict. reliable; [0003] The TV backplane needs to conduct electricity in some specific areas, but the VCM film-coated board is completely non-conductive after coating. Riveting studs are set at the position of the TV set. This method will lead to a complex structure of the TV backplane, and the production process is cumbersome and greatly reduces production efficiency. Therefore, the present invention proposes a film-coating method for a TV backplane to solve the deficiencies in the prior art. Contents of the invention [0004] In view of the above problems, the purpose of the pr...
