[0002] When welding a battery pack, manual labor is often used to move the battery pack and the metal connecting piece to move the welding point to the bottom of the welding end. Manual operation is inefficient, sparks are emitted during welding, and moving the battery pack and the metal connecting piece by hand is dangerous. In addition, the battery pack has multiple welding points that need to be welded, and the welding points need to be moved manually to the bottom of the welding end. The accuracy of the movement position of the battery pack and the metal connecting piece is determined visually by the operator, which may result in a large error. Even if the error is too large, it will directly lead to the scrapping of the battery pack. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0017] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0018] Example 1: An automatic electrode welding device for an automotive power battery assembly line, see Figures 1 to 2 , including a battery conveyor 1 and an electrode sheet conveyor 2, a support column 3 is provided between the battery conveyor 1 and the electrode sheet conveyor 2, a cylinder 31 is installed on the top of the support column 3, a driving motor 32 is installed on the driving end of the cylinder 31, a horizontal plate 33 is installed on the driving end of the driving motor 32, bottom plates 34 are provided on both sides of the bottom of the horizontal plate 33, telescopic rods 35 are provided on both sides of the bottom of the two bottom plates 34, and suction cups 37 are installed on the bottoms of the four telescopic rods 35. The battery surface on the battery conveyor 1 and the motor surface on the electrode sheet conveyor 2 are on the same horizontal plane; a frame 4 is provided on one side of the battery conveyor 1, and an electrode welding machine 41 is provided on the frame 4. When working, the batteries and electrode sheets are conveyed respectively by the battery conveyor 1 and the electrode sheet conveyor 2, When the battery and electrode sheet are conveyed to the bottom of the suction cup 37, the cylinder 31 is started to pull the suction cup 37 into contact with the electrode sheet to adsorb the electrode sheet, and then the cylinder 31 lifts the cross plate 33 to make the electrode sheet separate from the electrode sheet conveyor 2, and then the drive motor 32 is started to drive the cross bar to rotate 180°, so that the electrode sheet adsorbed on the suction cup 37 corresponds to the battery pole, and then the cylinder 31 is started to pull the cross plate 33 to move so that the electrode sheet on the suction cup 37 corresponds to the battery pole, and then the electrode sheet and the battery are welded by the electrode welding machine 41, thereby reducing the error of manual welding by personnel and further improving the quality of electrode sheet welding. When the electrode sheet is welded, the other suction cup 37 adsorbs the electrode sheet on the electrode sheet conveyor 2, so that the electrode sheets of the battery can be welded continuously, further improving the efficiency of battery electrode sheet welding.

[0019] For details, see Figure 2 The bottom of the base plate 34 is provided with an adjustment slot 5, and a bidirectional screw rod 51 is rotatably connected between the two sides of the inner cavity of the adjustment slot 5. An adjustment block 52 is slidably connected in the adjustment slot 5, and the two adjustment blocks 52 are respectively threadedly sleeved on the outside of the two sides of the bidirectional screw rod 51. The telescopic rod 35 is connected to the adjustment block 52, and one end of the bidirectional screw rod 51 passes through the adjustment slot 5 and is placed on the outside. A handwheel 53 is installed at one end of the bidirectional screw rod 51. By holding the handwheel 53 and rotating it, the bidirectional screw rod 51 is driven to rotate to adjust the distance between the two suction cups 37 on the same side, thereby facilitating the correspondence of the two suction cups 37 on the same side with the poles on the battery, thereby facilitating the welding of electrode sheets for batteries of different sizes, further improving the practicality of the device.

[0020] For further information, see Figure 2 A spring 36 is sleeved on the outside of the telescopic rod 35, and one end of the spring 36 is connected to the adjustment block 52. When the cylinder 31 pulls the horizontal plate 33 downward to make the electrode sheet on the suction cup 37 contact the battery terminal, the spring 36 can buffer the downward impact force of the adsorption, thereby avoiding damage to the battery.

[0021] It is worth noting that see Figure 1 A chassis 38 is installed at the bottom of the support column 3. The size of the chassis 38 is larger than that of the support column 3. The chassis 38 increases the contact area between the support column 3 and the supporting surface, thereby improving the stability of the electrode sheet welding.
