[0003] With the rapid development of electric vehicles, power batteries, as an important component of electric vehicles, are subject to increasingly higher quality and performance requirements. As a key component in the battery production process, power battery cells require clamping devices to maintain stability during processing to ensure the safety of the cells during production operations.

[0004] However, the inventors found that existing battery cell clamping devices generally use a single structure to fix the battery cells, and then directly loosen the single structure to place the clamped battery cells into the jig. This makes the battery cell clamping device not ideal for fixing the battery cells during the clamping process, and during the battery cell discharge process, due to the poor fixing effect, it is difficult to ensure that the adapter and the top cover are precisely in the same area. Utility Model Content

DETAILED DESCRIPTION

[0023] The specific implementation of this embodiment is described below with reference to the accompanying drawings.

[0024] Reference Figure 1 An embodiment of the utility model provides a power soft-connect battery cell clamping device, comprising a first mounting plate 7, a clamping claw tensioning cylinder 1 is fixed to the bottom of the first mounting plate 7, and the two ends of the clamping claw tensioning cylinder 1 are respectively fixedly connected to two symmetrically arranged second mounting plates 8.

[0025] Furthermore, the first mounting plate 7 is a plate-shaped structure, which facilitates the fixation of the bottom clamp tensioning cylinder 1 .

[0026] Reference Figure 2 , a cell clamping assembly for adjusting the degree of cell clamping is fixed to the inner side of the two second mounting plates 8; and the two second mounting plates 8 are connected by a third mounting plate 12, on which a cell tensioning cylinder 2 is provided, and a cell opening plate 4 is fixedly connected to the bottom of the cell tensioning cylinder 2; at the same time, the top of the third mounting plate 12 is fixedly connected to the bottom of the first mounting plate 7.

[0027] Since the cell opening plate 4 is located between the two cell cells squeezed by the cell pressing assembly, that is, between the A cell 3 and the B cell 13; therefore, when the cell pressing assembly releases the squeezed A cell 3 and the B cell 13, the cell tensioning cylinder 2 is actuated to drive the cell opening plate 4 to move outward, thereby separating the A cell 3 and the B cell 13.

[0028] Reference Figure 2 The cell clamping assembly includes a pair of first slide rails 10, an anti-collision mechanism 5, and a fourth mounting plate 9. Specifically, the two first slide rails 10 are symmetrically fixed near the ends of the inner side of the second mounting plate 8. The anti-collision mechanism 5 is fixed to the second mounting plate 8 via the two first slide rails 10. The top of the fourth mounting plate 9 is fixed to the anti-collision mechanism 5 by screws. Preferably, the anti-collision mechanism can be linked with the entire clamping device. When the anti-collision mechanism rubs against other mechanisms, an alarm is triggered and the entire clamping device is shut down, thereby preventing the installation of equipment between mechanisms.

[0029] Preferably, the first mounting plate 7, the second mounting plate 8, the third mounting plate 12 and the fourth mounting plate 9 can be sheet metal parts, or can be plate materials made by other processes; the present invention does not impose any restrictions here.

[0030] Furthermore, the battery cell clamping assembly also includes a pair of clamping cylinders 6 and a pair of battery cell clamps 11. Specifically, the two clamping cylinders 6 are symmetrically fixed to the outer side of the fourth mounting plate 9 near the two end positions by screws; the two battery cell clamps 11 are symmetrically fixed to the bottom of the fourth mounting plate 9 near the two end positions by screws.

[0031] The material used for the two battery cell clamps 11 is rubber, which can provide a firm clamping force while ensuring the stability of the battery cell during the production process of being clamped by the battery cell clamps. That is, as the mechanism moves, the battery cell adapter and the top cover will not shift. Therefore, this design can improve work efficiency and battery safety.

[0032] It should be noted that fixing by screws is only a specific implementation method in this embodiment, and other suitable fixing methods can also be used; the present invention does not limit this here.

[0033] Furthermore, the bottoms of the two pressing cylinders 6 respectively contact the A and B cells, while the tops of the two cell clamps 11 contact the A and B cells. This means that the A and B cells are clamped between the pressing cylinders 6 and the cell clamps. Therefore, by controlling the extension and contraction of the pressing cylinders, the degree of compression applied to the A and B cells can be controlled, enhancing the fixation of the cells.

[0034] Reference Figure 1 A pair of second slide rails 14 and a pair of third slide rails 15 are fixed to the bottom of the first mounting plate 7. The two second slide rails 14 and the two third slide rails 15 are symmetrical to each other. Furthermore, the two second slide rails 14 are symmetrically fixed to one side of the first mounting plate 7, and the two third slide rails 15 are symmetrically fixed to the other side of the first mounting plate 7. The two second slide rails 14 are fixedly connected to one of the two second mounting plates 8, and the two third slide rails 15 are fixedly connected to the other of the two second mounting plates 8.

[0035] Therefore, when the jaw tensioning cylinder 1 is in motion, the extension and contraction of the jaw tensioning cylinder 1 can drive the two second mounting plates 8 to move along the second slide rail and the third slide rail respectively. Then, the second mounting plate 8 will successively drive the first slide rail, the fourth mounting plate, and the battery cell jaw to move.

[0036] Working principle:

[0037] During the battery production process, when the battery cell clamp 11 grabs the battery cell and places the battery cell in the professional jig, the battery cell pressing assembly releases the battery cell by the action of the pressing cylinder 6; then, the battery cell tensioning cylinder 2 is actuated, that is, the battery cell tensioning cylinder 2 is retracted outward, driving the battery cell opening plate 4 to move outward, and then the A battery cell 3 and the B battery cell 13 are stretched apart; then, the stretched A battery cell 3 and the B battery cell 13 are placed in the jig, and before placing them, the stretching degree of the battery cell tensioning cylinder 2 can be adjusted to control the stretching degree of the A battery cell 3 and the B battery cell 13 distance, and then ensure that the battery cell adapter is in the same position as the top cover in the fixture; finally, the clamp tensioning cylinder 1 is actuated, and through the connection between the various mechanisms, that is, the extension and contraction of the clamp tensioning cylinder 1 drives the two second mounting plates 8 to move along the second slide rail and the third slide rail respectively, and then the second mounting plate 8 successively drives the first slide rail, the fourth mounting plate, and the battery cell clamp to move. When the battery cell clamp 11 moves to both sides to exceed the length of the A battery cell and the B battery cell, the battery cell clamp 11 releases the battery cell, and the A battery cell 3 and the B battery cell 13 will be accurately placed in the fixture.

[0038] Therefore, the utility model can improve the fixing effect of the battery cell clamping device on the battery cell during the clamping process, and can ensure the consistency of the adapter plate and the top cover area during the battery cell discharge process, thereby improving the quality of the battery.

[0039] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
