Description

Technical Field

[0001] The utility model relates to the technical field of LED display module production, in particular to a tray fixture suitable for an angled bottom shell. Background Art

[0002] LED display modules are commonly used to display various information such as text, images, videos, and video signals, and are widely used in advertising. During the production and assembly process of LED display modules, fixtures are required to automatically lock the bottom shell and PCB board of the LED display module, such as Figure 1 and Figure 2 The fixture structure shown includes a rectangular receiving groove 1' for placing the bottom shell 2' of the module. The side wall of the receiving groove 1' is provided with a plurality of fixing buckles 3' that can be movably extended into the receiving groove 1' to fix the bottom shell 2'. The fixture is suitable for the right-angle bottom shell 2'. The right-angle screen products of the existing outdoor LED display modules are two-sided beveled or four-sided beveled bottom shells (collectively referred to as beveled bottom shells). If the above fixture is used in the assembly link of the product production process, the following problems will occur:

[0003] ① When the module is screwed or glued, the module will tilt and warp when the screws are locked because the inclined surface of the angled bottom shell has no support, which will damage the module and affect the product pass rate and production efficiency.

[0004] ② When the screws are locked, the module is positioned by using an ejector cylinder on the screw machine track. Due to the structural characteristics of the angled bottom shell, the contact area between the fixed block when the cylinder is ejected and the side of the angled bottom shell is too small, resulting in low stability and ineffective positioning.

[0005] ③ When the conventional module is aged, because the conventional right-angle bottom shell 2' has grooves all around, it can be directly inserted into the aging rack. At present, the angled bottom shell cannot be realized, and the aging rack can only be put on the aging rack for aging by locking magnets, which is cumbersome and inefficient. Utility Model Content
