[0022] One of the application embodiments of the assembly fixture for the lens face cover is applied to the assembly of the module, mainly the assembly between the lens face cover 6 and the heat dissipation structure 7. Please refer to the attached Figures 1 to 3 In the figure, the surface of the lens face cover 6 has convex ribs 61, the heat dissipation structure 7 has mounting holes 71, the assembly fixture 1 includes a mold core 2, a slider 3, a guide post 4 and a spring 5. The mold core 2 has a groove 21 matching the convex ribs 61, and the slider 3 has a small guide post 31 matching the mounting holes 71.

[0023] The lens face cover 6 is inverted in the mold core 2, and the lens face cover 6 is accurately positioned through the convex ribs 61 and the groove 21. The heat dissipation structure 7 is fixed to the slider 3 through the small guide post 31, so that the heat dissipation structure 7 can be accurately assembled with the lens face cover 6.

[0024] The slider 3 can slide freely on the guide post 4. The spring 5 is located below the slider 3, and the spring 5 is sleeved on the guide post 4. After placing the heat dissipation structure 7 and the lens face cover 6, a downward acting force is applied to the heat dissipation structure 7 by a pressure block 8 through a press. The pressure block 8 distributes the pressure evenly to the heat dissipation structure 7. Through the positioning action of the convex ribs 61 and the small guide post 31, the accurate assembly of the lens face cover 6 and the heat dissipation structure 7 is realized without damaging the lens face cover. When a single assembly operation is completed, the slider 3 can be reset by the resilience of the spring 5 for the next operation.
