Their electrolyte system is between liquid and all-solid-state, retaining both the high ionic conductivity of liquid electrolytes and enhancing mechanical stability and thermal safety through the introduction of solid components. The processing and manufacturing process of soft-pack batteries play a decisive role in their performance and quality. Specifically, multiple sheet-shaped battery cores are assembled together, and the assembled sheet-shaped battery cores are placed in a casing, and then the casing is welded to complete the processing of the soft-pack battery.

[0003] During the welding process of the casing, a clamping tool is used to fix the soft-pack battery.

When flipping the soft-pack battery, the clamping tool needs to be opened, and the soft-pack battery is lifted above the clamping tool for flipping. After flipping, the soft-pack battery is then placed back into the clamping tool. Therefore, there is an urgent need for a device that can efficiently open and close the clamping tool.

A clamping space is formed between the fixed clamping plate 4 and the moving clamping plate 14. The bearing plate 3 is a square plate-like structure. Walking wheels are provided at the four corners of the bearing plate 3.

[0026] Two groups of guide rods are arranged on the movable splint 14, one group of guide rods corresponds to one connecting block 6, 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 sliding rod 16, and one end of the guide rod is fixedly connected to the movable splint 14, and a guide hole for the corresponding guide rod to slide is opened on the connecting block 6.

[0027] In this embodiment, a protective pad is fixedly connected to the side of the movable clamping plate 14 and the fixed clamping plate 4 near the clamping space. The protective pad is made of elastic rubber material to protect the surface of the shell. A pad fixedly connected to the bearing plate 3 is arranged between the movable clamping plate 14 and the fixed clamping plate 4. The pad is connected to the bearing plate 3 by bolts. The pad is not only used to support the bottom plate, but also to form an avoidance gap between the bottom plate and the bearing plate 3 for the clamping claws to extend into in the subsequent process, so as to ensure that the clamping claws can smoothly grab the soft-pack battery 5 in the subsequent process.

[0028] The opening and closing device includes a control unit and a support frame 13 fixed on the machine tool 1. The support frame 13 includes two oppositely arranged vertical rods and a horizontal rod.

Figure 1 As shown, the bottom end of the vertical rod is fixedly connected with a connecting piece, which is a rectangular plate-shaped structure. The connecting piece is fixedly connected to the machine tool 1, and the connection method of the two is bolt connection; the two ends of the horizontal rod are respectively fixedly connected to the top ends of the two vertical rods, and the connection method of the two is bolt connection.

[0029] An installation plate 8 is arranged on the support frame 13, and the installation plate 8 is driven to move vertically by a plurality of first cylinders 12; specifically, a plurality of slide rails 11 extending in the vertical direction are fixedly arranged on the support frame 13. In this embodiment, the number of slide rails 11 is two, and the two slide rails 11 are respectively fixed on two vertical rods. The connection mode between the slide rail 11 and the vertical rod is bolt connection; sliders corresponding to the slide rails 11 are arranged on the installation plate 8. Correspondingly, the number of sliders is two, which are respectively located at two ends of the installation plate 8, and the sliders can reciprocate along the slide rails 11. The installation mode of the first cylinder 12 is that a fixed plate is arranged on the support frame 13, the fixed plate is fixedly connected to the top of the vertical rod, and the connection mode between the two is bolt connection. The first cylinder 12 is installed on the fixed plate; connection ears are vertically and fixedly connected to the installation plate 8. The connection ears are located at two ends of the installation plate 8 and are respectively connected to the two first cylinders 12. The piston end of the first cylinder 12 is fixedly connected to the connection ear, so that the first cylinder 12 pushes the installation plate 8 to move up and down.

[0030] Hook 10 is arranged on the installation plate 8. During the vertical movement of the installation plate 8, the hook 10 can be connected to or separated from the moving clamping plate 14 of the clamping tooling. The hook 10 is driven to move horizontally by a plurality of second cylinders 9 fixed on the installation plate 8; the second cylinder 9 is fixed in the middle of the installation plate 8. A connecting plate is fixedly connected to the piston end of the second cylinder 9, and the hook 10 is fixed on the connecting plate. The hook 10 has a hook groove with the opening facing downwards. During the vertical movement of the installation plate 8, the pull plate 7 can enter or exit the hook groove.

[0031] In this embodiment, the control unit is electrically connected to both the first cylinder 12 and the second cylinder 9, and is used to control the start and stop of the first cylinder 12 and the second cylinder 9, as well as control the stroke of the piston.

[0032] In this embodiment, a positioning assembly is provided on the machine tool 1. The positioning assembly includes a positioning cylinder 18 fixedly installed on the installation track of the speed-changing line 2. A fixed seat is fixedly connected below the installation track, and the positioning cylinder 18 is fixedly installed on the fixed seat. The top end of the piston of the positioning cylinder 18 is fixedly connected with a base 19. A first swing wheel 20 and a second swing wheel 22 are rotatably arranged on the base 19. A vertical plate 21 is arranged on the first swing wheel 20, and the vertical plate 21 is fixedly connected with the outer side wall of the first swing wheel 20. A horizontal plate 23 is arranged on the second swing wheel 22, and the horizontal plate 23 is fixedly connected with the outer side wall of the second swing wheel 22. A positioning groove 17 for accommodating the vertical plate is formed on the carrier plate 3. When the soft-pack battery 5 is conveyed, the positioning assembly is located below the carrier plate 3 to ensure the smooth passing of the soft-pack battery 5. When the carrier plate 3 is at the processing station, the transmission mechanism pauses working. The positioning cylinder 18 pushes the base 19 to move upward, the vertical plate 21 enters the positioning groove 17, and the horizontal plate 23 contacts the lower surface of the carrier plate 3 to position it. In the present invention, when the carrier plate 3 is misaligned due to inertia, during the upward movement of the base 19, the vertical plate 21 will deflect and enter the positioning groove 17. And as the vertical plate enters the positioning groove 17, the first swing wheel 20 will push the carrier plate 3 to correct its position, thereby ensuring that the pull plate 7 can accurately enter the hook groove.

[0033] The working process of the present invention is as follows. When it is necessary to open the clamping tooling, the first cylinder 12 pushes the mounting plate 8 to move downward, thereby driving the hook 10 to move downward until the pull plate 7 enters the hook groove, and the first cylinder 12 locks the mounting plate 8; the second cylinder 9 drives the hook 10 to move in a direction away from the fixed clamping plate 4, thereby driving the movable clamping plate 14 to move in a direction away from the fixed clamping plate 4 to open the clamping tooling. After the flipping is completed, after placing the soft-pack battery 5 on the cushion block, the second cylinder 9 drives the hook 10 to move in a direction towards the fixed clamping plate 4, thereby pushing the movable clamping plate 14 to move in a direction towards the fixed clamping plate 4 to the required position. The first cylinder 12 drives the mounting plate 8 to move upward to the initial position of the mounting plate 8, and the movable clamping plate 14 clamps the soft-pack battery 5 under the action of the spring 15.
