[0031] This utility model embodiment provides a lithium battery 6 sealing device, such as Figures 1-3 As shown, it includes:

[0032] The housing 1 has an opening on one side wall for inserting the lithium battery 6 to be sealed.

[0033] Multiple side positioning plates 2 are arranged in parallel and spaced within the housing 1. Between adjacent side positioning plates 2 is a receiving groove 10 for accommodating a lithium battery 6 to be sealed. The side positioning plates 2 are slidably connected to the housing 1. A slider 11 can be set on the side positioning plate 2. The housing 1 has a sliding groove for the slider 11 to slide. Preferably, the slider 11 is fixed at the bottom of the side positioning plate 2 and can be fixed in one piece.

[0034] A drive assembly for synchronously moving multiple side positioning plates 2 closer or further away, the drive assembly includes a scissor mechanism 12 and a power mechanism for extending and retracting the scissor mechanism 12, the slider 11 is hinged to the cross hinge point of the scissor mechanism 12.

[0035] During operation, multiple lithium batteries 6 to be sealed are placed into multiple receiving slots 10. Then, the scissor mechanism 12 is shortened by the power mechanism. The scissor mechanism 12 drives multiple side positioning plates 2 to move closer simultaneously. The adjacent side positioning plates 2 fix the lithium batteries 6 to be sealed. It can fix multiple lithium batteries 6 to be sealed simultaneously and can adapt to lithium batteries 6 of different sizes, thus improving adaptability.

[0036] The power mechanism includes:

[0037] The bidirectional lead screw 14, which is rotatably mounted on the housing 1, can be rotatably mounted via a bearing and a bearing seat. The length direction of the bidirectional lead screw 14 is perpendicular to the extension and retraction direction of the scissor mechanism 12.

[0038] The first stepper motor 13, which is fixed on the housing 1, can be fixed by bolts and is used to drive the bidirectional lead screw 14 to rotate. The output shaft of the first stepper motor 13 can be fixedly connected to one end of the bidirectional lead screw 14 through a coupling.

[0039] An internal threaded sleeve 15 is threadedly connected to the two threaded sections of the bidirectional lead screw 14. The internal threaded sleeve 15 is slidably connected to the housing 1 to restrict the rotation of the internal threaded sleeve 15.

[0040] Two sliding sleeves 17 are provided between two internal threaded sleeves 15. The two sliding sleeves 17 are respectively hinged to the two end hinge points of the scissor mechanism 12. A tension spring 16 is fixedly connected between the internal threaded sleeve 15 and the adjacent sliding sleeve 17. Preferably, the tension spring 16 is fitted on the bidirectional lead screw 14.

[0041] During operation, the lithium battery 6 is placed in the receiving slot 10, and the first stepper motor 13 is started. The first stepper motor 13 drives the two internal threaded sleeves 15 away. The two internal threaded sleeves 15 pull the two sliding sleeves 17 away through the tension spring 16. The two sliding sleeves 17 drive the scissor mechanism 12 to shorten. The scissor mechanism 12 drives the adjacent side positioning plates 2 to move closer through the slider 11, so as to synchronously position all lithium batteries 6. When the size of the lithium battery 6 changes, the deformation of the tension spring 16 can adapt, and it can fix lithium batteries 6 of different sizes.

[0042] In this embodiment, arc-shaped elastic sheets 7 are fixed to the lower part of both sides of the side positioning plate 2. The arc apex of the arc-shaped elastic sheet 7 is close to the lithium battery 6. When the side positioning plate 2 is close to the lithium battery 6, the arc-shaped elastic sheet 7 abuts against the side of the lithium battery 6 and gradually fits together, changing from line contact to surface contact, thereby improving the fixing effect.

[0043] In practice, an upper positioning component is installed between adjacent side positioning plates 2 above the lithium battery 6 to press down on the lithium battery 6 for positioning.

[0044] Specifically, the upper positioning component includes:

[0045] Mounting plate 8, on which two connecting rods 4 are symmetrically hinged, and the two connecting rods 4 are respectively hinged to the side walls of the two side positioning plates 2.

[0046] A movable rod 5 is vertically mounted on the mounting plate 8. An upper positioning plate 3 is fixed to the bottom end of the movable rod 5. A compression spring 9 is fitted on the movable rod 5 between the mounting plate 8 and the positioning plate.

[0047] When two adjacent side positioning plates 2 approach each other, the mounting plate 8 is driven to descend via the connecting rod 4. The mounting plate 8 drives the upper positioning plate 3 to descend, and the upper positioning plate 3 presses down on the top of the lithium battery 6 for positioning.

[0048] In this embodiment, the lithium battery 6 sealing device further includes a sealing assembly, which includes:

[0049] A pressure plate 18 is provided on one side of the opening of the housing 1 for sealing the lithium battery 6. The pressure plate 18 is fixed to the telescopic end of the electric push rod 19.

[0050] The electric push rod 19 is fixed to the telescopic end of the second stepper motor 20, which is bolted to the frame (not shown in the figure). Figure 3 As shown, during sealing, the electric push rod 19 extends to bring the pressure plate 18 close to the lithium battery 6 and then seals it. After sealing, the second stepper motor 20 drives the electric push rod 19 and the pressure plate 18 to rotate 180 degrees, which facilitates the feeding of the lithium battery 6, such as by using the existing technology of robotic arms for feeding.

[0051] In summary, this utility model provides a lithium battery sealing device, the working principle of which is as follows:

[0052] Multiple lithium batteries 6 to be sealed are placed into multiple receiving slots 10. The first stepper motor 13 is started. The first stepper motor 13 drives two internal threaded sleeves 15 away. The two internal threaded sleeves 15 pull two sliding sleeves 17 away through the tension spring 16. The two sliding sleeves 17 drive the scissor mechanism 12 to shorten. The scissor mechanism 12 drives the adjacent side positioning plates 2 to move closer through the slider 11, and positions all lithium batteries 6 synchronously. When two adjacent side positioning plates 2 move closer, the mounting plate 8 is driven down through the connecting rod 4. The mounting plate 8 drives the upper positioning plate 3 to move down. The upper positioning plate 3 presses down the top of the lithium battery 6 for positioning.
