The driving mechanism includes a slide groove 21, and the slide groove 21 is arranged at the top of the bottom plate 1. The inside of the slide groove 21 is rotatably connected with a screw rod 22. One end of the screw rod 22 located outside the slide groove 21 is fixedly connected with a motor 24. The outer wall of the screw rod 22 located inside the slide groove 21 is threadedly connected with a slider 23. The screw rod 22 drives the slider 23. The top end of the slider 23 is fixedly connected to the bottom end of the welding device 27. The slider 23 The width is equal to the width of the slide groove 21, the outer wall of the slider 23 is slidably connected to the inner wall of the slide groove 21, and the slide groove 21 plays a limiting role in the movement of the slider 23. When the welding device 27 needs to be moved, the power of the motor 24 is turned on, and the output shaft of the motor 24 drives the screw 22 to rotate. By utilizing the threaded connection between the screw 22 and the slider 23, the screw 22 drives the slider 23 to move inside the slide groove 21 under the action of limiting and guiding the slide groove 21, thereby driving the upper welding device 27 to move.

[0022] Preferably, an operating table 2 is provided above the base plate 1, and a cylinder 3 is symmetrically fixedly connected to the top of the base plate 1, and the top of the cylinder 3 is fixedly connected to the bottom of the operating table 2. When the operating table 2 needs to be raised or lowered, the cylinder 3 is started, and the cylinder 3 drives the operating table 2 to move in the vertical direction. During the lifting and lowering process of the operating table 2, the driving assembly can be used to drive the positioning mechanism to fix the battery pack.

[0023] Furthermore, a positioning mechanism is arranged inside the operating table 2 for positioning the battery pack. The positioning mechanism includes two rectangular through slots 201. The two rectangular through slots 201 are symmetrically arranged at the top of the operating table 2. The two rectangular through slots 201 penetrate the operating table 2. A clamping plate 4 is arranged inside the rectangular through slots 201. Limiting components for the clamping plate 4 are arranged on both sides of the rectangular through slots 201. The limiting components include two strip grooves 7. The length of the strip grooves 7 is equal to that of the rectangular through slots 201. The two strip grooves 7 The inner part of the strip groove 7 is symmetrically arranged inside the rectangular through groove 201, and the inner part of the strip groove 7 is slidably connected to the limiting block 8. The limiting block 8 is located outside the strip groove 7 and is fixedly connected to the two sides of the clamping plate 4. The top ends of the two opposite sides of the two clamping plates 4 are fixedly connected with the clamping parts 5. The side of the clamping part 5 away from the clamping plate 4 is provided with an anti-skid pad 6. The anti-skid pad 6 plays an anti-skid role when the clamping plate 4 clamps the battery pack. The two clamping plates 4 are symmetrically provided with wedge blocks 12 on the opposite sides. A certain distance is left between the two wedge blocks 12. A reset assembly is provided in the middle of the side where the two wedge blocks 12 are separated from each other. The reset assembly includes a spring 18. The spring 18 is fixedly connected to the two sides where the two clamps 4 are separated from each other.

The clamping plates 4 are subjected to a component force in the horizontal direction, driving the two clamping plates 4 to slide relative to each other inside the rectangular through groove 201, so that the anti-skid pad 6 contacts and clamps the battery pack. When the positioning of the battery pack is released, the cylinder 3 is used to drive the operating table 2 to descend or ascend. During the process of the operating table 2 descending or ascending, until the rotating wheel 16 and the middle of the clamping plates 4 are at the same height, the two clamping plates 4 are constantly subjected to the force of the spring 18, causing the clamping plates 4 to slide inside the rectangular through groove 201 and break away from the fixation on the battery pack.

[0024] Furthermore, a driving assembly for driving the positioning mechanism to position the battery pack is provided at the top of the base plate 1, and the driving assembly includes two rectangular columns 14, which are symmetrically fixedly connected to the top of the base plate 1, and a rectangular hole 13 is provided at the top of the operating table 2 at the position of the rectangular through groove 201, the rectangular hole 13 is connected to the rectangular through groove 201, and the rectangular hole 13 runs through the operating table 2, the inside of the rectangular hole 13 is slidably connected to the outer wall of the rectangular column 14, and the two rectangular columns 14 are located on the opposite sides of the rectangular hole 13 and are fixedly connected with a fixed block 15, the inner side of the fixed block 15 is fixedly connected with a first fixed shaft 17, and the outer wall of the first fixed shaft 17 is rotatably connected with a rotating wheel 16, during the lifting and lowering process of the operating table 2, the rotating wheel 16 squeezes the wedge block 12, and by utilizing the rotating connection between the rotating wheel 16 and the first fixed shaft 17, the rotating wheel 16 can roll on the inclined surface of the wedge block 12, which can reduce the friction between the rotating wheel 16 and the wedge block 12.

[0025] Finally, the rolling component is arranged at the top and bottom of the limit block 8 located inside the strip groove 7, and is used for limiting the position of the splint 4 when sliding inside the rectangular through groove 201. The rolling component includes an inner groove 9, which is rectangular in shape and is arranged at the top and bottom of the limit block 8. The interior of the inner groove 9 is fixedly connected with a second fixed shaft 11, and the outer wall of the second fixed shaft 11 is rotatably connected with a roller 10. The outer wall of the roller 10 located on the outer side of the inner groove 9 is fitly connected with the interior of the strip groove 7. In the process of the rotating wheel 16 or the spring 18 driving the splint 4 to move inside the rectangular through groove 201, the limit block 8 slides inside the strip groove 7, and the second fixed shaft 11 is connected with the roller 10 in rotation, so that the outer wall of the roller 10 located on the outer side of the inner groove 9 rolls with the interior of the strip groove 7, so that the sliding friction between the outer wall of the limit block 8 and the interior of the strip groove 7 is converted into rolling friction, thereby reducing the friction between the limit block 8 and the strip groove 7.

The oil filling pipe 25 is U-shaped, and the oil outlet 26 is symmetrically arranged on the inner side of the oil filling pipe 25. The oil filling port 28 can be connected to the lubricating oil pipe, and the lubricating oil can be injected into the interior of the oil filling pipe 25. The lubricating oil flows from the oil outlet 26 in the oil filling pipe 25 into the interior of the slide groove 21, which can reduce the friction of the slider 23 when sliding inside the slide groove 21.

[0027] The working principle of the above embodiment is: When welding the battery pack, the battery pack can be placed on the top of the operating table 2, and the cylinder 3 is started. According to the size of the battery pack, the cylinder 3 drives the operating table 2 to descend or ascend, and the rotating wheel 16 squeezes the wedge block 12 to clamp the battery pack with the clamp 4. The motor 24 is started to drive the slider 23 to move horizontally, thereby driving the welding device 27 to weld the battery pack.

[0028] By arranging an operating table, a cylinder, a rectangular through slot, a clamp, a wedge block, a rectangular column, a fixed block and a rotating wheel, when the cylinder drives the operating table to rise and fall, the clamp positions the battery pack by squeezing the wedge block by the rotating wheel, thereby solving the problem that the existing battery pack processing table cannot be raised or lowered.
