[0025] Specifically, the unit voice coil automatic spot welding device is a mechanical device specially used for automatic welding of unit voice coils. This device realizes the automation, efficiency and precision of the voice coil welding process by adopting advanced welding technology and control system. The unit voice coil is an important part of the speaker, and its welding quality directly affects the performance and sound quality of the speaker. The smoke shield 201 installed at the lower part of the spot welder 103 in the automatic spot welding machine 100 can isolate and protect the smoke generated during the spot welding at the bottom of the spot welder 103, and the smoke can be blown away by the micro fan on one side of the smoke shield 201. 202 blows the generated smoke to the bottom of the smoke removal pipe 204 on the other side of the smoke protection cover 201, so that the harmful smoke generated in the spot welding is sucked into the welding smoke purifier 205 through the smoke removal pipe 204 for purification, so as to prevent the smoke generated in the spot welding from drifting to the bottom of the visual camera 102 and polluting it, affecting its detection accuracy and accumulating in the external environment and affecting the safety of the staff. At the same time, the bottom protection plate 203 installed at the bottom of the smoke protection cover 201 below the micro fan 202 can also avoid the problem of the airflow blown by the micro fan 202 blowing the upper end welding harness of the lower voice coil.

[0026] Embodiment 2:

[0027] Based on the first embodiment, Figure 4 As shown, the adjustment component 300 includes a fixing seat 301 fixedly installed on the front part of the smoke shield 201, and a pin 302 movably installed in the fixing seat 301, and a spring 303 is also sleeved on the outer end of the pin 302, and the two ends of the spring 303 are respectively on the fixing seat 301 and the pin 302, and the adjustment component 300 also includes a socket row 304 concavely opened at the front end of the spot welder 103, and the pin 302 and the socket row 304 are matched.
