Specifically, the encapsulation material for pouch batteries is typically an aluminum-plastic film shell of a predetermined size. Then, an encapsulation device heat-seals the bare cell within the aluminum-plastic film shell, forming a single cell. However, current encapsulation devices not only have low encapsulation efficiency but also suffer from precision issues during the encapsulation process, leading to problems such as incomplete sealing. This, in turn, results in difficult subsequent processing steps and poor encapsulation quality for pouch batteries. Summary of the Invention

[0036] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0038] In the description of this invention, "multiple" means two or more, and "greater than" or "less than" are understood to exclude the stated number. The use of "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or their sequential relationship.

[0039] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0040] Figure 1 This is a top view of one embodiment of the present invention, with reference to... Figure 1 One embodiment of the present invention provides a soft-pack battery fixture, including a conveying device 100, a clamping fixture 200 disposed on the conveying device 100, the clamping fixture 200 being used to clamp the battery, and the conveying device 100 being used to move the clamping fixture 200 to various workstation positions.

[0041] Furthermore, refer to Figure 2 , Figure 3 The clamping fixture 200 includes an upper movable clamping plate 220 and a lower fixed clamping plate 210. The movable clamping plate 220 and the fixed clamping plate 210 cooperate to clamp the battery (closed state). The movable clamping plate 220 and the fixed clamping plate 210 face the front of the clamping fixture 200. The movable clamping plate 220 is rotated and moved by the movable clamping plate control device 240 to open the clamping fixture 200 (open state).

[0042] Furthermore, the movable clamping plate 220 is connected to the movable clamping plate control device 240 via a rotating component 230. That is, the movable clamping plate control device 240 controls the rotation of the rotating component 230, which in turn drives the movable clamping plate 220 to rotate. The rotating component 230 includes a middle clamping plate connecting portion 231 and left and right balancing connecting portions 232. The clamping plate connecting portion 231 is connected to the movable clamping plate 220, and the balancing connecting portions 232 are connected to the movable clamping plate control device 240.

[0043] Furthermore, the balancing connection portion 232 is shaped like a "ㄩ" and has an opening. The balancing connection portion 232 faces the rear of the clamping fixture 200, and the opening of the balancing connection portion 232 faces the front of the clamping fixture 200. The balancing connection portion 232 plays a balancing role for the movable clamping plate 220.

[0044] In actual operation, the movable clamping plate 220 and the fixed clamping plate 210 work together to clamp the battery (closed state). After the conveying device 100 moves the clamping fixture 200 to the corresponding workstation position, the movable clamping plate control device 240 controls the rotating component 230 to rotate, thereby causing the movable clamping plate 220 to flip backward, opening the movable clamping plate 220 (open state). During the flipping process of the movable clamping plate 220, the balancing connection part 232 of the rotating component 230 plays a balancing role for the movable clamping plate 220, making the flipping process of the movable clamping plate 220 more stable, especially when the movable clamping plate 220 is closed. This is of great significance for large-sized batteries, as it can increase the speed when the movable clamping plate 220 is open and prevent damage to the aluminum-plastic film when the movable clamping plate 220 is closed.

[0045] In some embodiments, the movable clamping plate 220 and the fixed clamping plate 210 are provided with suction cups, which are used to hold the aluminum-plastic film so that the clamping fixture 200 can hold the aluminum-plastic film in the open or closed state and control the opening and closing of the aluminum-plastic film.

[0046] It is conceivable that the suction cup is connected to a vacuum pumping device. The specific implementation of the vacuum pumping device is not further limited.

[0047] In some embodiments, the movable clamping plate 220 and the fixed clamping plate 210 are provided with a slot 201. The left side of the slot 201 is the clamping plate cell-covering area 202, and the right side of the slot 201 is the clamping plate aluminum-plastic film reserved area 203. The clamping plate cell-covering area 202 corresponds to clamping the aluminum-plastic film-covered cell portion. The clamping plate aluminum-plastic film reserved area 203 corresponds to clamping the empty portion of the aluminum-plastic film-covered cell, which is used for subsequent processing. The slot 201 facilitates the gripper to pick up and put down the battery; specifically, the slot 201 is for the gripper's claws to hold the battery.

[0048] In some embodiments, the length of the movable clamp 220 is a1, the length of the balancing connection portion 232 is b1, the width of the movable clamp 220 is a2, and the width of the balancing connection portion 232 is b2. The values ​​of a1, b1, a2, and b2 satisfy the condition that b1 ≥ 0.7a1 and b2 ≥ 1.2a2. This ensures the balancing effect of the balancing connection portion 232.

[0049] It is conceivable that the weight of the balancing connection part 232 will also affect the balancing effect, which will not be elaborated further.

[0050] In some embodiments, the movable clamping plate control device 240 includes a movable clamping plate bearing seat 241, a movable clamping plate movable gear 242, a movable clamping plate linkage gear 243, and a movable clamping plate linkage swing member 244. The movable clamping plate 220 rotates along the movable clamping plate bearing seat 241. The movable clamping plate linkage gear 243 is connected to the movable clamping plate 220 and meshes with the movable clamping plate linkage gear 243. The movable clamping plate linkage swing member 244 is used to control the rotation of the movable clamping plate linkage gear 243, thereby controlling the rotation of the movable clamping plate 220.

[0051] A pull rod 245 is provided between the movable clamping plate linkage gear 243 and the movable clamping plate linkage swing component 244. The movable clamping plate linkage swing component 244 is connected to the movable clamping plate active control swing component 247 through the movable clamping plate linkage rotating rod 246. When the movable clamping plate active control swing component 247 reciprocates, it pulls the movable clamping plate linkage gear 243 to rotate through the pull rod 245.

[0052] Some embodiments, refer to Figure 1 A soft-pack battery coating device includes the aforementioned soft-pack battery fixture, wherein the soft-pack battery fixture is applicable to the soft-pack battery coating device.

[0053] In some embodiments, the conveying device 100 has a turntable structure, with various clamping fixtures 200 distributed around the edge of the conveying device 100.

[0054] In some embodiments, the soft-pack battery packaging device of the present invention further includes a feeding device 110 for placing the aluminum-plastic film onto the clamping fixture 200.

[0055] In some embodiments, the soft-pack battery packaging device of the present invention further includes a folding and alignment device 300. The folding and alignment device 300 pushes out a fold crease on the aluminum-plastic film through a folding plate 310, and then the movable clamping plate 220 and the fixed clamping plate 210 of the clamping fixture 200 are closed to fold the aluminum-plastic film in half. In this way, the fold crease of the folded aluminum-plastic film can be smoother, avoiding misalignment, wrinkles, or other issues that would affect the folding effect and result in a better wrapping effect.

[0056] In some embodiments, the soft-pack battery packaging device of the present invention further includes a length cutting device 410, which cuts the front part of the aluminum-plastic film through the front cutting module 430. The length cutting device 410 is only responsible for cutting the excess part of the front part of the aluminum-plastic film, which makes it easier to control the cutting accuracy, reduces the technical requirements of the cutting device, and is more conducive to automated control.

[0057] In some embodiments, the soft-pack battery packaging device of the present invention further includes a width cutting device 420, which cuts the aluminum-plastic film on the left and right sides through cutting modules 430 on the left and right sides. The width cutting device 420 is only responsible for cutting the excess part on the left and right sides of the aluminum-plastic film, which makes it easier to control the cutting accuracy, reduces the technical requirements of the cutting device, and is more conducive to automated control.

[0058] In some embodiments, the soft-pack battery packing device of the present invention further includes a cell loading device 500. After the clamping fixture 200 opens the aluminum-plastic film, the cell loading device 500 places the cell on the aluminum-plastic film, and then the clamping fixture 200 closes the aluminum-plastic film.

[0059] In some embodiments, the soft-pack battery packing device of the present invention further includes a top sealing device 610, which seals the front edge of the aluminum-plastic film through the front sealing module 630.

[0060] In some embodiments, the soft-pack battery packaging device of the present invention further includes a side sealing device 620, which processes the aluminum-plastic film into a battery by sealing the left and right sides of the film with sealing modules 630 on the left and right sides.

[0061] In some embodiments, the soft-pack battery coating apparatus of the present invention further includes a discharge device 120 for discharging the processed battery.

[0062] Some embodiments, refer to Figure 4 The folding and alignment device 300 includes a folding and alignment device stand 320, and a tilting advance device 330 is provided on the folding and alignment device stand 320. The tilting advance device 330 is used to control the folding plate 310 to extend obliquely and press against the aluminum-plastic film.

[0063] Some embodiments, refer to Figure 5 The cutting module 430 includes an upper cutter 431, an upper cutter mounting plate 432, an upper cutter cylinder 433, a lower cutter 434, a lower cutter mounting plate 435, and a lower cutter cylinder 436. The upper cutter 431 is connected to the upper cutter cylinder 433 via the upper cutter mounting plate 432, and the upper cutter cylinder 433 controls the raising and lowering of the upper cutter 431. The lower cutter 434 is connected to the lower cutter cylinder 436 via the lower cutter mounting plate 435, and the lower cutter cylinder 436 controls the raising and lowering of the lower cutter 434. The upper cutter 431 and the lower cutter 434 work together to cut off the excess portion of the aluminum-plastic film.

[0064] In some embodiments, the battery cell loading device 500 includes a battery cell loading robot 510, see reference. Figure 6The battery cell loading robot 510 includes a central battery cell pressure plate 511 and left and right battery cell gripping claws 513. The pressure plate 511 is equipped with a pressure plate lifting cylinder 512, and the gripping claws 513 are equipped with gripping claw translation cylinders 514. When the battery cell loading device 500 grips the battery cell using the gripping claws 513, the battery cell is simultaneously pressed down by the pressure plate 511. This prevents the battery cell from becoming misaligned or even scattering during transport, which would affect the testing results and product quality.

[0065] Some embodiments, refer to Figure 7 The edge-sealing module 630 includes an edge-sealing lifting guide rail 631, an upper edge-sealing section 632, an upper edge-sealing control motor 633, an upper edge-sealing connecting rod 634, a lower edge-sealing section 635, and a lower edge-sealing cylinder 636. The upper edge-sealing section 632 and the lower edge-sealing section 635 can move up and down along the edge-sealing lifting guide rail 631. During actual edge-sealing work, the lower edge-sealing cylinder 636 first controls the lower edge-sealing section 635 to rise, and then the upper edge-sealing control motor 633 drives the upper edge-sealing connecting rod 634 to control the upper edge-sealing section 632 to descend, cooperating with the lower edge-sealing section 635 to press the aluminum-plastic film for edge sealing. This edge-sealing method ensures a flatter and tighter edge-sealing position and a better edge-sealing effect.

[0066] In this embodiment, optionally, heaters are provided in the upper sealing portion 632 and the lower sealing portion 635 to cooperate with the sealing module 630 for heat sealing.

[0067] In this embodiment, optionally, the upper sealing link 634 includes a first link and a second link. The upper sealing control motor 633 controls the first link to rotate, and then the first link drives the second link to pull the upper sealing part 632 to move up and down reciprocally. This allows the upper sealing part 632 to apply greater and more stable pressure during sealing, ensuring the sealing effect.
