[0027] Working principle:

[0028] During use, the workpiece 5 is first conveyed by the conveyor belt 4. When the workpiece 5 moves to the spot welding position, the conveyor belt 4 stops running. At this time, the electric push rod 7 located on the side wall of the support frame 2 starts to work, and its output shaft pushes the connecting block 8 and the baffle rod 9 fixedly connected thereto to move, thereby clamping and limiting the workpiece 5 to ensure its stability during the spot welding process. Then, the spot welding machine body 13 starts to work, and its core parts include a laser emitter, an output head and a lens adjustment mechanism. The laser emitter generates a laser beam, which is focused by the lens of the output head to form a light spot. The stepper motor in the lens adjustment mechanism drives the lens to move inside the output head under the control of the controller 26, thereby changing the focusing distance of the laser beam and realizing precise adjustment of the light spot size. This adjustment process can be automatically controlled according to the input workpiece 5 and welding spot size information to ensure accuracy and efficiency during the welding process. After the spot welding of the workpiece 5 is completed, the pickup assembly starts to work, and the turntable 15 rotates under the action of the drive device. , the circular groove 16 and the air suction hole 17 on it contact with the workpiece 5, and at the same time the fan 20 starts to work, and the cavity inside the turntable 15 is connected with the inside of the fan 20 through the air suction pipe 21, forming a negative pressure. This negative pressure makes the workpiece 5 adsorbed in the circular groove 16 and move with the rotation of the turntable 15. When the turntable 15 rotates to a certain angle, the pneumatic rotor 19 starts to work, pushing the rotating rod 18 and the turntable 15 to rotate in a small range, so that the workpiece 5 is separated from the circular groove 16 and moves under the action of gravity. During this process, the baffle 24 on the fixed rod 22 blocks the rotating rod 18 under the action of the torsion spring 25, ensuring that the rotating rod 18 and the turntable 15 can rotate according to the predetermined trajectory. Finally, when the workpiece 5 is spot welded and separated from the picking assembly, the sprinkler 11 in the storage box 10 starts to work, spraying cleaning water to the inside of the workpiece 5 through the hose 12, cleaning the residue generated by welding, and cooling the workpiece 5 to ensure the quality and performance of the workpiece 5.
