[0002] In recent years, with the growing demand for safe, high-energy-density energy storage devices in the new energy industry, soft-pack batteries have attracted significant attention due to their unique electrolyte system design. By utilizing a solid-liquid hybrid electrolyte, this technology maintains the excellent ion mobility of a liquid electrolyte system while also providing the battery with enhanced mechanical strength and thermal stability through the solid component. This unique property holds great potential for soft-pack batteries in applications such as electric vehicles and large-scale energy storage.

[0003] In terms of manufacturing process, soft-pack batteries typically adopt a multi-layer stacked structure design. The battery cells are stacked, then installed in a metal shell and laser welded to form a soft-pack battery. The welding quality directly affects the performance of the battery.

When conveying the soft-pack battery, the lower surface of the carrier plate 17 is placed on the speed-doubling line 3. The walking wheels are in contact with the side wall of the installation track of the speed-doubling line 3. When the speed-doubling line 3 drives the clamping unit to move, the walking wheels rotate along the installation track, reducing the friction between the installation track and the clamping unit.

[0035] The fixed cleat 18 is configured such that a first intermediate plate is fixedly connected to the carrier plate 17. The fixed cleat 18 and the first intermediate plate are fixedly connected by bolts. Multiple reinforcing plates are provided between the fixed cleat 18 and the first intermediate plate to enhance the stability of the fixed cleat 18. The movable cleat 26 is configured such that a mounting block 29 fixedly connected to the carrier plate 17 is provided on the side of the movable cleat 26 facing away from the fixed cleat 18. A spring 28 is provided between the mounting block 29 and the movable cleat 26 to push the movable cleat 26 toward the fixed cleat 18. Specifically, there are two mounting blocks 29, which are distributed along the length direction of the movable splint 26. The mounting block 29 is connected to the bearing plate 17 by bolt connection. A connecting rod 27 is slidably provided on the mounting block 29. The connecting rod 27 is a cylindrical structure. A through hole is provided on the connecting block for the connecting rod 27 to pass through, and the through hole and the connecting rod 27 are clearance-fitted. One end of the connecting rod 27 is fixedly connected to the movable splint 26, and the other end of the connecting rod 27 passes through the mounting block 29 and is fixedly connected to the pull plate 30. In this embodiment, the two connecting rods 27 are connected to the same pull plate 30; the spring 28 is sleeved on the part of the connecting rod 27 located between the mounting block 29 and the movable splint 26, one end of the spring 28 abuts against the movable splint 26, and the other end of the spring 28 abuts against the mounting block 29.

[0036] Two groups of guide rods are provided on the movable splint 26, one group of guide rods corresponds to one mounting block 29, and each group of guide rods has two guide rods. Taking one group of guide rods as an example, the two guide rods are located on both sides of the connecting rod 27, and one end of the guide rod is fixedly connected to the movable splint 26, and a guide hole for the corresponding guide rod to slide is opened on the mounting block 29.

[0037] In this embodiment, protective pads are fixedly connected to the side of the movable clamping plate 26 and the fixed clamping plate 18 near the clamping space. The protective pads are made of elastic rubber and protect the outer shell surface. A pad is fixedly connected to the support plate 17 between the movable clamping plate 26 and the fixed clamping plate 18. The pad is connected to the support plate 17 by bolts. The pad is not only used to support the soft-pack battery, but also creates an escape gap between the lower surface of the soft-pack battery and the support plate 17 for the clamping jaws 12 to extend into, ensuring that the clamping jaws 12 can smoothly grasp the soft-pack battery.

[0038] A positioning assembly is provided on the machine tool 1. The positioning assembly includes a positioning cylinder 19 fixedly installed on the installation track of the speed-changing line 3. A fixed seat is fixedly connected below the track, and the positioning cylinder 19 is fixedly installed on the fixed seat. The top end of the piston of the positioning cylinder 19 is fixedly connected with a base 20. A first swing wheel 21 and a second swing wheel are rotatably arranged on the base 20. A vertical plate is arranged on the first swing wheel 21 and is fixedly connected with the outer side wall of the first swing wheel 21. A horizontal plate 22 is arranged on the second swing wheel and is fixedly connected with the outer side wall of the second swing wheel. A positioning groove 23 for accommodating the vertical plate is formed on the bearing plate 17. When the soft-pack battery is being conveyed, the positioning assembly is located below the bearing plate 17 to ensure the smooth passage of the soft-pack battery.

The vertical plate enters the positioning groove 23, and the horizontal plate 22 contacts the lower surface of the bearing plate 17 to position it. When the bearing plate 17 is misaligned due to inertia, during the upward movement of the base 20, the vertical plate will deflect and enter the positioning groove 23. And as the vertical plate enters the positioning groove 23, the first swing wheel 21 will push the bearing plate 17 to correct its position, so as to ensure that the end of the soft-pack battery can be accurately located between the two clamping jaws 12.

[0039] In this embodiment, a baffle 16 is fixedly connected to the machine tool 1. The baffle 16 is vertically arranged and its top end is bent upward towards the upper side of the bearing plate 17 to form a blocking portion for blocking the upward movement of the bearing plate 17.

[0041] The working process of this mechanism is as follows: The soft-pack battery is transported by the speed-changing line 3 to between the two clamping jaws 12. The second cylinder 34 drives the two connecting plates 10 to move towards each other, and then drives the two clamping jaws 12 to move towards each other, so that the two ends of the soft-pack battery respectively abut against the corresponding clamping blocks 13; pull the pull plate 30 to release the clamping of the soft-pack battery; the first cylinder 4 drives the support plate 8 to move upward, and then drives the clamping jaws 12 and the soft-pack battery fixed between the two clamping jaws 12 to move upward, so that it moves out of the clamping space. After moving to the required position, it is locked. The camera 24 collects the image of the soft-pack battery and transmits it to the control unit to identify and detect the weld seam. Then, the drive motor 11 drives the clamping jaws 12 to rotate, and then drives the soft-pack battery to rotate to collect the weld seams on different surfaces of the soft-pack battery until the detection is completed. The first cylinder 4 drives the support plate 8 to move downward, driving the detected soft-pack battery into the clamping space. Under the action of the spring 28, the moving clamping plate 26 and the fixed clamping plate 18 clamp the soft-pack battery and convey it to the next station through the speed-changing line 3.
