After the material picking claw puts the inner rearview mirror into the clamping tool 416, the clamping tool 416 moves to the bottom of the pressing device for the pressing process. After the pressing is completed, the clamping tool 416 moves to one end of the clamping slide rail 415 close to the finished product testing mechanism.

[0085] The finished product test assembly 42 includes a finished product test clamp and a finished product test box arranged on the fourth workbench.

When two defective products are placed on the buffer plate 441, the pushing cylinder 442 drives the pushing column 443 to extend from one end of the buffer plate 441 into the buffer plate 441, thereby pushing the defective products on the outside out of the buffer plate 441 to realize the unloading of defective products.

[0090] The working process of the utility model is as follows:

[0091] Ball head seat assembly mechanism 1000: glue the bracket 5, lock the triangular spring piece in the bracket 5, sleeve the clamping spring 13 on the outside of the ball head seat 6, and press the ball head at the end of the bracket 5 into the ball head seat 6.

[0092] Mirror assembly mechanism 2000: firstly, the substrate 8 is locked on the ball head seat 6, and the substrate 8 is subjected to plasma activation surface treatment, and then the film 10 is attached to the lens 9, and then the lens 9 and the substrate 8 are pressed tightly by the pressure-maintaining component 22.

[0093] Mainboard installation mechanism 3000: lock the PCB mainboard to the back of the substrate 8, and solder the leads to the mainboard to complete the PCB data binding, and then the staff pre-presses the back shell 12 onto the substrate 8.

[0094] Machine testing organization 4000: First, pre-test the interior rearview mirror to detect the anti-glare effect, then fully press the interior rearview mirror, and finally test the reflectivity of the lens 9 on the finished product.

[0095] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
