It should be noted that the squeeze box 20 is filled with liquid, and the slope of the slope rod 46 can change the height of the support rod 43.

[0028] Specific use: At the beginning, the batteries and insulating plates are placed in the loading boxes 14 of the loading unit 1 7 and the loading unit 2 8. The batteries in the two loading boxes 14 are placed in reverse order to facilitate the device to perform parallel welding of the batteries. The linear motor 25 of the clamping unit 2 10 is started. The linear motor 25 moves on the guide rail 3. The linear motor 25 moves to the loading port of the loading box 14 of the loading unit 1 7. The touch block 1 30 on the side wall of the linear motor 25 contacts the touch switch 2 33 on the bottom wall of the loading box 14 of the loading unit 1 7, and the linear motor 25 stops. The movable end of the electric push rod 15 extends to push the battery and the insulating plate into the middle of the clamping plate 18. The battery contacts the touch switch 12, and the electric push rod 15 retracts. The linear motor 25 of the clamping unit 10 continues to move, and the linear motor 25 of the clamping unit 9 starts to move forward. The linear motor 25 of the clamping unit 10 moves to the other end of the mounting seat 1 and then stops. The linear motor 25 of the clamping unit 9 repeats the loading operation of the clamping unit 10 at the feeding port of the loading box 14 of the loading unit 8, and then the linear motor 25 of the clamping unit 9 continues to move; When the linear motor 25 of the clamping unit 19 moves to the linear motor 25 of the clamping unit 210, the squeezing box 20 of the clamping unit 19 contacts the squeezing box 20 of the clamping unit 210, and the squeezing box 20 squeezes the liquid stored therein. The hydraulic pressure generated by the squeezed liquid causes the telescopic sleeve 27 to extend, thereby driving the slider 28 to move downward. The downward movement of the slider 28 drives the slider 1 21 to move downward, thereby driving the baffle 18 to move downward. The squeezing box 20 continues to be squeezed until its surface is flush with the surface of the clamping plate 18. At this time, the slider 1 It has dropped to the baffle 23. At this time, the surfaces of the clamping plates 18 of the clamping unit 1 9 and the clamping unit 2 10 are in contact and squeezed against each other. The slider 1 21 can continue to move by squeezing the baffle 23 to avoid getting stuck, so that the extrusion box 20 can continue to be squeezed and the clamping plate 18 continues to move downward. When the linear motor 25 of the clamping unit 1 9 and the linear motor 25 of the clamping unit 2 10 are in contact, the top wall of the clamping plate 18 is flush with the top wall of the support block 19, and the clamping unit 1 9 and the clamping unit 2 10 are merged. After the battery is merged, it is tightly clamped. During the merging process of the clamping unit 1 9 and the clamping unit 2 10, the touch rod 1 32 on the side wall of the support block 19 of the clamping unit 1 9 contacts the slider 3 42, driving the slider 3 42 to move, the slider 3 42 drives the rack 44 to move, the rack 44 drives the gear 1 37 to rotate, the rotation of the gear 1 37 drives the support rod 36 to rotate, the adsorption rod 34 adsorbs the welding piece on the loading platform 39, and the height of the support rod 36 changes under the action of the slope rod 38, adsorbing and raising the welding piece, rotating it to above the battery electrode and then descending to the battery electrode, and then starting the welding head 35 to weld the battery electrode; After welding is completed, the linear motor 25 of the clamping unit 1 9 is started, and the clamping unit 1 9 and the clamping unit 2 10 continue to move. The touch rod 1 32 on the side wall of the clamping unit 1 9 continues to move, driving the slider 3 42 to move to the chute 2 43. The slider 3 42 can slide in the chute 2 43, so as not to affect the movement of the linear motor 25 of the clamping unit 1 9. If the clamping unit 1 9 and the clamping unit 2 10 move away from each other from the combined state, the extrusion box 20 is pushed out by the action of the spring 2 29. At this time, the slider 1 21 is pushed out by the baffle 23 under the action of the spring 1 24. The extrusion box 20 moves outward. Under the action of the hydraulic pressure, the telescopic sleeve 27 contracts and drives the slider 1 21 to move upward, thereby driving the clamp 18 to reset.

A touch rod three 56 is fixedly provided on the side wall of the linear motor 25 of the clamping unit four 51.

[0030] It should be noted that the lengths of the welding head 35 and the adsorption rod 34 of the welding unit three 47 and the welding head 35 and the adsorption rod 34 of the welding unit two 46 are longer than those of the welding unit one 11. The purpose of adding the gear two 54 and the gear three 57 is to change the rotation direction of the support rod 36 corresponding to the welding unit two 46 and the welding unit three 47 to avoid interference. The steering unit three 48 and the steering unit four 58 are at different heights on the L-shaped support plate 40 to avoid interference.
