[0002] With the continued development of new energy, soft-pack batteries have become a key focus of battery technology research and development and application, thanks to their significant advantages over traditional liquid batteries in terms of energy density and safety. Their electrolyte system lies somewhere between liquid and all-solid, retaining the high ionic conductivity of liquid electrolytes while improving mechanical stability and thermal safety through the introduction of solid components. The manufacturing process for soft-pack batteries plays a decisive role in their performance and quality. Specifically, multiple sheet-shaped cells are assembled together, placed in a casing, and then welded to complete the soft-pack battery manufacturing process.

[0003] During the shell welding process, a clamping tool is used to fix the soft-pack battery. First, the connection between the top plate and the side plate of the shell is welded. Then, the soft-pack battery is flipped 180° and the bottom plate is welded. 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 the flipping is completed, the soft-pack battery is placed in the clamping tool. Therefore, there is an urgent need for a device that can efficiently open and close the clamping tool.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further elaborated in detail below in conjunction with specific embodiments. Parts not described and disclosed in detail in the following embodiments of the present invention should be understood as existing technologies known or should be known to those skilled in the art.

[0022] Example

[0023] A high-efficiency opening and closing device for a soft-pack battery clamping tooling, which is used on an automated production line for soft-pack batteries 5, efficiently opens and closes the clamping tooling, and improves the processing efficiency of the soft-pack batteries 5. A transmission mechanism for transmitting the soft-pack batteries 5 is provided on the machine tool 1, and the transmission mechanism has two mutually parallel speed lines 2. In this embodiment, the mounting track of the speed line 2 is fixedly connected to the machine tool 1, and the connection between the two is a bolt connection. The clamping tooling is installed on the speed line 2, driving the clamping tooling to move along the speed line 2, and performing processing at different workstations.

[0024] The clamping tooling includes a carrier plate 3, a fixed splint 4 fixedly arranged on the carrier plate 3, and a movable splint 14 slidably arranged on the carrier plate 3, and a clamping space is formed between the fixed splint 4 and the movable splint 14. The carrier plate 3 is a square plate-like structure, and the four corners of the carrier plate 3 are provided with running wheels. Specifically, the four corners of the carrier plate 3 are provided with grooves, and a mounting plate fixedly connected to the carrier plate 3 is provided above the groove, and the mounting plate and the carrier plate 3 are connected in a bolted manner; a mounting shaft is fixedly connected to the mounting plate, and the axis of the mounting shaft is perpendicular to the carrier plate 3. The running wheel is rotatably arranged at the bottom of the mounting shaft and is located in the groove. When the soft-pack battery 5 is conveyed, the lower surface of the carrier plate 3 is placed on the speed line 2, and the running wheel contacts the side wall of the mounting track of the speed line 2. When the speed line 2 drives the clamping tooling to move, the running wheel rotates along the mounting track of the speed line 2, reducing the friction between the mounting track and the clamping tooling.

[0025] The fixed splint 4 is arranged in such a manner that an intermediate plate is fixedly connected to the supporting plate 3, and the fixed splint 4 and the intermediate plate are fixedly connected by bolts. A plurality of reinforcing plates are arranged between the fixed splint 4 and the intermediate plate to improve the stability of the fixed splint 4. The movable splint 14 is arranged in such a manner that a plurality of connecting blocks 6 are fixedly arranged on the supporting plate 3. The connecting blocks 6 are located on the side of the movable splint 14 facing away from the fixed splint 4. There are two connecting blocks 6 and they are distributed along the length of the movable splint 14. The connecting blocks 6 are connected to the supporting plate 3 by bolts. A sliding rod 16 is slidably arranged on the connecting block 6. The sliding rod 16 is a cylindrical structure. The connecting block 6 has a through hole for the sliding rod 16 to pass through. The through hole and the sliding rod 16 are in a clearance fit. One end of the sliding rod 16 is fixedly connected to the movable splint 14, and the other end of the sliding rod 16 passes through the connecting block 6. The ends of the two sliding rods 16 located on the side of the mounting block facing away from the movable splint 14 are jointly connected to the pull plate 7. A spring 15 is provided between the connecting block 6 and the movable splint 14. The spring 15 is sleeved on the slide rod 16 and is used to push the movable splint 14 toward the fixed splint 4, that is, one end of the spring 15 abuts against the movable splint 14, and the other end of the spring 15 abuts against the connecting block 6.

[0026] Two groups of guide rods are provided 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 is opened on the connecting block 6 for the corresponding guide rod to slide.

[0027] In this embodiment, protective pads are fixedly connected to the movable clamping plate 14 and the fixed clamping plate 4 on one side near the clamping space. These pads are made of elastic rubber and protect the outer shell surface. A pad is fixedly connected to the support plate 3 between the movable clamping plate 14 and the fixed clamping plate 4. The pad is bolted to the support plate 3. The pad not only supports the base plate but also creates a clearance between the base plate and the support plate 3 for the clamping claws to enter during subsequent steps, ensuring that the clamping claws can smoothly grasp the soft-pack battery 5 in the subsequent steps.

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

[0029] A mounting plate 8 is provided on the support frame 13, and the mounting 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 provided on the support frame 13. In this embodiment, there are two slide rails 11, and the two slide rails 11 are respectively fixed to the two vertical rods. The slide rails 11 and the vertical rods are connected by bolts. The mounting plate 8 is provided with sliders corresponding to the slide rails 11. Accordingly, there are two sliders, respectively located at the two ends of the mounting plate 8, and the sliders can reciprocate along the slide rails 11. The first cylinders 12 are installed in the following manner: a fixed plate is provided on the support frame 13, and the fixed plate is fixedly connected to the top of the vertical rods. The two are connected by bolts, and the first cylinders 12 are mounted on the fixed plate. Connecting ears are vertically fixedly connected to the mounting plate 8. The connecting ears are located at both ends of the mounting plate 8 and are respectively connected to the two first cylinders 12. The piston ends of the first cylinders 12 are fixedly connected to the connecting ears, thereby causing the first cylinders 12 to push the mounting plate 8 up and down.

[0030] A hook 10 is provided on the mounting plate 8. During the vertical movement of the mounting plate 8, the hook 10 can be connected to or separated from the movable clamping plate 14 of the clamping tooling. The hook 10 is driven to move horizontally by a number of second cylinders 9 fixed on the mounting plate 8; the second cylinder 9 is fixed to the middle of the mounting plate 8, and the end of the piston of the second cylinder 9 is fixedly connected to a connecting plate, and the hook 10 is fixed to the connecting plate. The hook 10 has a hook groove with an opening facing downward. During the vertical movement of the mounting plate 8, the pulling plate 7 can enter or exit the hook groove.

[0031] In this embodiment, the control unit is electrically connected to 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, and control the stroke of the piston.

[0032] In this embodiment, the machine tool 1 is provided with a positioning assembly, which includes a positioning cylinder 18 fixedly mounted on the mounting rail of the speed line 2, a fixed seat fixedly connected to the bottom of the mounting rail, the positioning cylinder 18 fixedly mounted on the fixed seat, the top of the piston of the positioning cylinder 18 fixedly connected to the base 19, a first swing wheel 20 and a second swing wheel 22 rotatably provided on the base 19, and a vertical plate 21 is provided on the first swing wheel 20, and the vertical plate 21 is fixedly connected to the outer wall of the first swing wheel 20, and a horizontal plate 23 is provided on the second swing wheel 22, and the horizontal plate 23 is fixedly connected to the outer wall of the second swing wheel 22, and a positioning groove 17 for accommodating the vertical plate is provided 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 that the soft-pack battery 5 passes smoothly. When the carrier plate 3 is located at the processing station, the transmission mechanism stops 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 supporting plate 3 is dislocated due to inertia, the vertical plate 21 will be deflected and enter the positioning groove 17 during the rising process of the base 19, and as the vertical plate enters the positioning groove 17, the first swing wheel 20 will push the supporting plate 3 to correct its position, thereby ensuring that the pulling plate 7 can accurately enter the hook groove.

[0033] The working process of the present invention is as follows: when the clamping tool needs to be opened, the first cylinder 12 pushes the mounting plate 8 downward, thereby driving the hook 10 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 away from the fixed splint 4, thereby driving the movable splint 14 to move away from the fixed splint 4, thereby opening the clamping tool. After the flip is completed, the soft-pack battery 5 is placed on the pad. The second cylinder 9 drives the hook 10 to move toward the fixed splint 4, thereby driving the movable splint 14 to move toward the fixed splint 4 to the desired position. The first cylinder 12 drives the mounting plate 8 upward to its initial position. The movable splint 14 clamps the soft-pack battery 5 under the action of the spring 15.
