The first cylinder 158 drives the pneumatic finger 155 to grab the vibrator 32 to be welded placed on the product pre-positioning tooling assembly 4 to the preheating platform 29, and the system will automatically time the vibrator grabbed on the preheating platform 29.

The vibrator grasping component 3 of this embodiment can grasp two vibrators 32 to be welded at the same time to improve production efficiency. Connecting tooth limit blocks 166 are installed on both sides of the fifth guide rail 120 to prevent the slider from exceeding the travel of the guide rail.

[0048] See also Figure 6, in the specific implementation, the welding tool 49 is manually placed on the product positioning block 74 of the welding assembly 9. After pressing the second start button 57, the third motor 58 is driven by the communication control component 6 to move a certain distance, and the first welding point of the preheated vibrator 113 to be welded on the welding tool 49 is just aligned with the nozzle of the flux recovery barrel 50, and the spraying amount and spraying time of the flux are controlled by the communication control component 6, and then the flux is sprayed on the second welding point.

The communication control assembly 6 is mounted on the electrical installation board 24 inside the steel frame 27. The servo driver is used to drive the servo motor. The PLC module 168 controls the operation of the program through the touch control screen 12. The filter 174 increases the stable voltage for the switch power supply 169.

The bottom opening of the smoking pipe faces the jet tin furnace 48, so as to absorb the smoke generated during welding. The heating time and temperature of each vibrator, the welding parameters of the spray furnace and other display adjustments of welding parameters can be displayed on the touch control screen 12.
