Method for assembling frame-type bracket assemblies of television

Abstract

The invention discloses a method for assembling frame-type bracket assemblies of a television. Each single piece (1) of the bracket assemblies is sequentially located between a rivet holder (5) and a rivet head (6) according to the assembled requirement, the rivet head (6) is a standard cylinder or a tapering cylinder; the upper part of the rivet holder (5) is provided with a round groove, the center part of a circle of the groove is higher than the excircle part of the groove, the rivet head (6) and the rivet holder (5) align to the position needed for riveting, the rivet head (6) is punched downwards, and the punched part deforms in the rivet holder (5) through an instant process of strong pressurizing to form an internal-embedding and self-fastening riveted joint; and each located single piece (1) or the rivet holder (5) is moved to finish the connection of other riveted joints. By adopting the connection without rivets, the invention enables the riveted joint to have firm and reliable intensity and convenient and fast operation, saves coupling screws used in the former connection mode, avoids the misuse of screws, improves the production efficiency of assembling the bracket assemblies, and reduces the rejection rate.

Description

technical field [0001] The invention relates to an assembly method of a bracket assembly, in particular to an assembly method of a TV frame type bracket assembly. Background technique [0002] The flat-panel TV frame-type support assembly has the function of connecting modules (displays), control circuit boards, rear shells and bases, and is the skeleton of the TV set. Its original design adopts the overall structure. In order to reduce costs and save raw materials, the design is improved to frame-type assembled bracket parts. It is required that the hole positions be accurate and consistent, otherwise there will be damage, deformation, and installation difficulties of the connecting parts. In order to ensure that the position of the mounting holes in the bracket assembly is accurate and consistent, the positioning protrusions and holes are used to position the parts of the bracket and then fixed with screws to form the bracket parts. This processing method is due to the gap...

Problems solved by technology

In order to ensure that the position of the mounting holes in the bracket assembly is accurate and consistent, the positioning protrusions and holes are used to position the parts of the bracket and then fixed with screws to form the bracket parts. This processing method is due to the gap between the positioning protrusions and the matching holes. , and canceling the gap is difficult to assemble, so the relative position between the parts can be changed after its positioning, then the dimensional consistency of the bracket assembly after being fixed with screws is poor, the pass rate is low, and the production efficiency is low

Moreover, such a processing method requires a large number of screws. According to statistics, the amount of screws used for each bracket part is 10 to 40. For example, the annual production of flat-panel TVs of an enterprise reaches 8 million sets. For example, each TV uses 25 screws on average. According to calculations, the annual consumption will reach about 200 million pieces, and there are many kinds of screw specifications. It is inevitable that wrong screws will be used in production, which brings inconvenience to material management and production organization, and is not conducive to energy saving. Reduce consumption and save resources

However, the welding connection is expensive, difficult to operate, and expensive. It is difficult to connect multi-layer material plates and plated plates or aluminum, copper and stainless steel parts. For sprayed plates, plates of different materials, Plates with too large thickness differences and plates with interlayers in the middle cannot be connected; at the same time, spot welding damages the surface coating of the plates, which will cause thermal deformation, and all unreliable factors in the processing process cannot be automatically monitored without damage
