Edge-curled steel-plastic back plate for displayer and manufacturing method thereof

Abstract

The invention provides an edge-curled steel-plastic back plate for a displayer and a manufacturing method thereof. The manufacturing method comprises the following steps that firstly, a steel-plasticplate is cut to form the shape of an unfolded edge-curled steel-plastic back plate, wherein the steel-plastic back plate comprises a thick body structure and thin body structures located on the periphery of the thick body structure; pre-edge-curling treatment and pre-bending treatment are conducted on the thin body structures of the steel-plastic plate to form to-be-curled and to-be-bent structures; each thin body structure of the steel-plastic plate is bent by 90 degrees to form a bent structure; and the end of each bent structure is subjected to edge curling or edge rolling treatment from bottom to top to form a curled body structure. According to the edge-curled steel-plastic back plate for the displayer and the manufacturing method thereof, the problems of edge curling and bending of the steel-plastic plate are solved, the stability of edge curling and bending of the steel-plastic plate is ensured, mass production of edge curling and bending of the steel-plastic plates is realized,the defect that a traditional steel-plastic plate cannot be bent is overcome, and the utilization space of a film-coated plate is widened; and the procedures are reduced, and the purposes of reducingmanpower and material resources and reducing the cost are achieved.

Description

technical field [0001] The invention belongs to the technical field of steel-plastic panels, and in particular relates to a rolled-edge steel-plastic backplane for displays and a manufacturing method thereof. Background technique [0002] Most of the back shells of existing LCD TV screens and LCD monitors are composed of three parts. The front part is a module display assembly carried by a back plate stamped and formed from a metal sheet, and the middle part is a central control board composed of various circuit boards. Integrated, the outer part is a plastic back cover. The module and the circuit board of the display device are respectively installed on the front side and the rear side of the backplane, and the plastic cover wraps the circuit board for protection. With the development of thinner LCD screens, in order to pursue the visual ultra-thin effect, the central control integration and rear cover that were originally scattered on the back of the back panel are gradua...

AI Technical Summary

Problems solved by technology

[0003] The existing steel-plastic panels are formed by pressing two layers of iron plates and plastic plates between the two layers of iron plates, and then cut into steel-plastic panels of specified sizes by slitting. The ultra-thin back plate is required, but the plastic plate in the middle of the steel-plastic plate is difficult to bend and shape, and can only be used for general punching and cutting processing
