The main control panel 27 is installed on the work cabinet 1 through a fixed bracket 26 and can rotate along the fixed bracket 26.

[0052] The process flow of this equipment is as follows: First, the buzzer's outer shell 24 is coated with glue by the outer shell assembly device and then sent to the positioning cavity in the upper limit fixture 3 of the rotary track 2. Driven by the first push cylinder 4, the upper limit fixture 3 is pushed to the buzzer piece assembly device, where the buzzer piece 25 is installed on the outer shell 24 by the cooperation of the buzzer piece storage component and the buzzer piece gripping component. Then, the upper limit fixture 3 is pushed to the pin assembly device, where two pin feeding components attach two electrical pins 28 to the two outer shells 24 on the upper limit fixture 3 in sequence, and the pins 28 are fixed to the outer shell by the pin pressing mechanism and the pin hot riveting mechanism. Finally, the equipment passes through a welding device and a paint drying device for welding and coating with protective paint, thus completing the entire processing flow. No manual assembly is required during this process, saving labor costs and improving work efficiency.

[0053] The dispensing detection module 10, buzzer detection module 11, hot riveting detection module 12, pressure resistance detection module, and good product detection module 13, which are set on the rotary track 2, are used to detect the processes completed by the shell assembly device, buzzer assembly device, and pin assembly device, respectively. The pressure resistance detection module and good product detection module 13 are used to complete the final inspection before material discharge. Good products are sent out by the good product conveyor belt 14, while defective products are driven to the fixed slide 21 by the sorting cylinder 19 and the receiving plate 20, thus completing the good product screening. When any of the detection modules detects a defective product, the subsequent process equipment will skip the operation on it to reduce unnecessary material waste.
