[0015] This invention discloses a dual-station welding device for sensors. The device utilizes a sliding mechanism to drive two clamping mechanisms in a reciprocating sliding motion. In the initial state, the sensor body is inserted into the clamping mechanism, with the sensor head protruding. A shearing mechanism cuts the sensor head to make it flat and further peels off the outer layer, exposing the conductive wire inside the sensor head. The sliding mechanism is activated to move the clamping mechanism, positioning the sensor head directly above the welding table. The material handling mechanism is then activated, with a rotary cylinder driving a gripper cylinder to rotate and grip the sensor piece. The rotary cylinder then resets, and a seventh cylinder moves a second sliding plate, positioning the sensor piece below the sensor body. A sixth cylinder is activated to move the welding table upwards, supporting the sensor piece and sensor body. The welding mechanism is then activated, with a ninth cylinder moving the welding head downwards to weld the sensor head and sensor piece, attaching a conductive wire from the sensor head to the sensor piece. After the ninth cylinder resets after welding, the eighth cylinder pushes the fourth slider to move, positioning the welding head directly above the other conductive wire on the sensor body head. The ninth cylinder then pushes the welding head down to weld the sensor body head and sensor sheet, welding both conductive wires of the sensor body onto the sensor sheet, completing the entire welding process. The cylinders then reset. Simultaneously, while welding, the head of another sensor body is inserted into another clamping mechanism, and a shearing mechanism cuts and peels it. After all cylinders reset, the other clamping mechanism moves another sensor body directly above the welding table, restarting the welding mechanism to weld the other sensor body. At the same time, the welded sensor is removed from the reset clamping mechanism and placed in a suitable position. A new sensor body is then inserted, and the above actions are repeated to complete all welding. This dual-station feeding system reduces waiting time, significantly improving the sensor welding speed and efficiency. Attached Figure Description

Then, the fourth cylinder 74 resets, and the sliding mechanism 3 is activated to push the clamping mechanism 4 to move, allowing the sensor to... The head of the sensor body 10 is positioned directly above the welding table 84.

After all the cylinders are reset, the other clamping mechanism 4 moves the other sensor body 10 to directly above the soldering table 84, and the soldering mechanism 9 is restarted to solder the other sensor body 10.
