Description

Manufacturing method of LED assembled screen bottom shell

technical field

The invention relates to the field of LED displays, in particular to a method for manufacturing a bottom case of an LED assembled screen. the

Background technique

Existing LED display screens include conventional display screens and strip screens, of which:

1) Conventional display screens, including heavy cabinets, are large in size and heavy in weight, have high requirements for installation carriers, and require a large maintenance space. The box body of conventional display screens is made by sheet metal and welding process. The processing accuracy is insufficient, the dimensional tolerance is difficult to guarantee, and there are risks of welding deformation and weld leakage. the

2) Strip screen, use the strip-shaped LED light strip to connect directly with the control box, with a through-hole connection in the middle, and use a silicone sealing ring and screw compression mode for waterproofing at the connection, through which the power and signal wires of the control box pass The through hole is connected to the strip LED light strip, which is small in size, light in weight, transparent, and relatively low in maintenance and installation costs. However, this kind of screen is limited by its structure, and the structural strength of its installation is insufficient, which is easy to cause damage due to external force collision. In order to overcome the lack of structural strength of the strip screen, an injection molding process is also used to make the bottom shell of the strip screen. However, when the injection molding process is used to produce large-scale and small-batch products, the cost of the mold is high and the cost is relatively high. the
