Method for producing front cover of display apparatus frame by laser beam welding device

Abstract

A manufacturing method of the division fence chassis top is provided as the process of being collective to the laser welding and end-product press is the series automated process in the matter supply. A manufacturing method of the division fence top chassis using the laser chamber type performs the followings: a step for pressing the divided parts from the supplied coil material(30); a step for dividing one set a step for arranging to the box type 2 parts(40); a step for welding the connected region of the divided parts which is arranged as laser to box type(50); and a step for completing the final finished product the product which is welded through the following press to the unique of the box type(60).

Description

technical field [0001] The present invention is a method of manufacturing a two-part display frame front cover by adopting a laser welding method. Joining the two split parts by laser welding embodies a new method of stamping and welding the split parts. At the same time, it improves production efficiency and improves product competitiveness and quality. It is a patent related to the use of laser welding to manufacture split display frame front covers. Background technique [0002] In recent years, with the continuous development of information processing devices, the demand for display devices (video devices, imaging devices) that play an intermediary role between users and information processing devices has increased rapidly. [0003] In particular, the development of high-definition television has been completed, the display device is particularly important. [0004] Well-known display devices generally include: a color cathode tube display device (CRT), a liquid crysta...

Problems solved by technology

[0019] However, the existing 2-split or 4-split display frame front cover is made by forced extrusion in the state where the contact surfaces of the components overlap each other, and it is difficult to set different pressures according to different materials. The production efficiency is not high, and the joint surface of the final product will have a convex hull of 0.8-1.0mm, which will have a certain impact on other parts. Excessive extrusion force will cause deformation of the parts and have a certain impact on the quality of the product

[0020] In addition, the method of laser welding after bending is not only a complicated process, but also the straight parts are bent at 90 degrees, and then laser welding is used for the bent part and the joint where there is no joint. The bending surface is not aligned, resulting in poor welding at the bend, etc., resulting in a decrease in product quality
