[0031] Currently, one method for installing LED chips and LED covers involves pressing them together with rollers. Since the cover's thickness is the same as the height of the LED chip, and it uses a locking point design to secure it to the bottom of the LED, this roller pressing process can be used for production. However, during product use, due to heat generation, the cover is prone to deformation, obstructing the LED's light-emitting angle and reducing the viewing angle of the display, thus affecting the display's performance. Therefore, covers with a thickness less than the LED's height have been developed to address this issue. However, using traditional roller pressing to press the cover and LED together can easily lead to uneven stress, potentially damaging the LED chip and resulting in poor assembly.

[0032] This utility model proposes a pneumatic assembly jig for LED module masks, aiming to provide a pneumatic assembly jig for LED module masks with uniform force distribution.
