[0030] The technical solution provided by this utility model will be described below with reference to the accompanying drawings and specific embodiments.

[0031] Combination Figures 1 to 3 As shown, this embodiment provides a battery cell loading mechanism. This mechanism can remove battery cells 100 produced or purchased from the blister pack and transport them to the assembly process in an evenly spaced arrangement, thereby achieving loading. The battery cell 100 can be a cylindrical cell, a square cell, or a pouch cell; this utility model is not limited to any of these.

[0032] Specifically, the battery cell loading mechanism includes an adjustment mechanism 1, a conveying mechanism 2, and a transfer mechanism 3. The conveying mechanism 2 includes several battery cell placement positions 221; the adjustment mechanism 1 includes a battery cell holder 11, a movable block 12, and a first driving member 13. The battery cell holder 11 carries the battery cell 100, and the multiple battery cell holders 11 are evenly spaced along a first direction, with the spacing between the battery cell holders 11 equal to the spacing between the battery cell placement positions 221; multiple battery cell holders 11 and movable blocks 12 are correspondingly provided, and the first driving member 13 is connected to the movable block 12 along the first direction to drive the battery cell 100 against the battery cell holder 11 via the movable block 12; the transfer mechanism 3 can transfer the adjusted battery cell 100 from the adjustment mechanism 1 to the multiple battery cell placement positions 221 of the conveying mechanism 2.

[0033] In this embodiment, reference Figure 2 As shown, the first direction is indicated by the bidirectional head marked X. The battery cell 100 is a square battery cell, and the first direction corresponds to the width direction of the battery cell 100. When the battery cell 100 is placed on the battery cell holder 11, the first driving member 13 can drive the movable block 12 to move along the first direction, so that the movable block 12 can push the position of the battery cell 100 on the battery cell holder 11 along the first direction, so as to realize the position adjustment of the battery cell 100 in the first direction, so that the battery cells 100 can maintain an equal spacing distribution. Then, the battery cells 100 with the adjusted spacing can be transferred to the conveying mechanism 2 by the transfer mechanism 3, so that the spacing of the battery cells 100 on the conveying mechanism 2 can meet the assembly requirements of the battery cells 100, which facilitates the feeding of the battery cells 100.

[0034] Optionally, the adjustment mechanism 1 further includes a linkage rod 14, the length direction of which is parallel to the first direction. Multiple movable blocks 12 are provided on the linkage rod 14, and one end of the movable rod is connected to the first driving member 13 to realize the simultaneous driving of multiple movable blocks 12 to move, which facilitates the simultaneous adjustment of the position of multiple battery cells 100.

[0035] In this embodiment, combined with Figure 2 , Figure 3 As shown, each battery cell holder 11 includes a support portion 111, a blocking portion 112, and a vertical fixing portion 113. The support portion 111 is used to place the battery cell 100. The blocking portion 112 and the vertical fixing portion 113 are arranged on both sides of the support portion 111 along a first direction. The blocking portion 112 is provided with a clearance hole 1121. Under the action of the first driving member 13, the movable block 12 can move along the first direction toward the vertical fixing portion 113 and can extend into the clearance hole 1121 to abut against the battery cell 100. This allows the battery cell 100 to be clamped between the movable block 12 and the vertical fixing portion 113, thereby restricting the movement of the battery cell 100 in the horizontal direction and preventing the battery cell 100 from being displaced or moved due to vibration or shaking.

[0036] Optionally, in this embodiment, a guide channel is provided at the bottom of the supporting part 111. The guide channel extends along the first direction, and the connecting rod 14 is slidably embedded in the guide channel. This allows the cell holder 11 to limit and block the connecting rod 14 along the second direction, enabling the cell holder 11 to support and guide the connecting rod 14, preventing deformation of the connecting rod 14 from affecting the adjustment of the cell spacing 100. In this embodiment, the second direction is represented by a double-headed arrow marked Y, and the first direction corresponds to the length direction of the cell 100.

[0037] Optionally, in this embodiment, the distance between the blocking part 112 and the vertical fixing part 113 is greater than the width of the battery cell 100, so as to facilitate the insertion of the battery cell 100.

[0038] Optionally, in this embodiment, the adjustment mechanism 1 further includes an adjustment member 15 and a second driving member 16 disposed on both sides of the cell holder 11 along the second direction. The second driving member 16 is tractively connected to the adjustment member 15 so that the adjustment member 15 can push the cell 100 along the second direction to adjust the position of the cell 100 in the second direction, ensuring that the cell 100 can be accurately placed on the cell placement position 221 of the conveying mechanism 2 after being grasped by the transfer mechanism 3.

[0039] In addition, the adjustment mechanism 1 provided in this embodiment also includes a displacement plate 17. Adjustment members 15 along the second direction and located on the same side of the cell holder 11 are all fixedly mounted on the displacement plate 17. The output end of the second driving member 16 is connected to the displacement plate 17, so that multiple adjustment members 15 can be moved simultaneously by driving the displacement plate 17, thereby simultaneously adjusting the position of the cell 100, which effectively improves the working efficiency.

[0040] Optionally, in this embodiment, the adjusting member 15 has a relief groove 151 on the side facing the battery cell 100. When the adjusting member 15 moves closer to the battery cell 100, the tab 110 at the end of the battery cell 100 can extend into the relief groove 151, which can protect the tab 110 and prevent damage or deformation that would affect assembly and use. In addition, the two ends of the relief groove 151 form abutment portions 153, so that the adjusting member 15 can contact the battery cell 100 portions on both sides of the tab 110 through the abutment portions 153, and the position of the battery cell 100 can be adjusted by pushing the battery cell 100 portions on both sides of the tab 110.

[0041] Optionally, in this embodiment, a waist-shaped groove 152 is formed on the surface of the adjusting member 15. The length direction of the waist-shaped groove 152 is parallel to the first direction. The displacement plate 17 and the adjusting member 15 can be fixed by a connector provided in the waist-shaped groove 152, and the adjusting member 15 can move relative to the displacement plate 17 in the first direction. This ensures that the clearance groove of the adjusting member 15 can accurately correspond to the tab 110 of the battery cell 100, and the abutting part 153 can accurately correspond to the battery cell 100 parts on both sides of the tab 110, ensuring the safety and stability of the battery cell 100 in the second direction adjustment process. The number of waist-shaped grooves 152 formed on the adjusting member 15 is not limited in this utility model. It can be one, two or more, as long as good connection stability between the adjusting member 15 and the displacement plate 17 is ensured.

[0042] Optionally, the adjustment structure provided in this embodiment also includes a support member (not shown in the figure). The support member is provided at the bottom of the bearing part 111 and is movably connected to the worktable 18 along the first direction. With the above arrangement, the battery cell feeding mechanism can adapt to different spacing requirements of the battery cells 100 and has stronger applicability.

[0043] refer to Figure 1As shown, in this embodiment, the conveying mechanism 2 includes a conveyor belt 21 and a plurality of limiting members 22 fixed on the conveyor belt 21. The limiting members 22 have the aforementioned cell placement positions 221, on which the cell 100 can be placed. The distance between the cell placement positions 221 meets the requirements for battery pack assembly. This not only ensures that the spacing between the cell 100 meets the requirements for battery pack assembly, but also limits the position of the cell 100 by the cell placement positions 221, preventing the cell 100 from slipping off the conveying mechanism 2, thereby ensuring the safety and stability of the cell 100 conveying.

[0044] Continue to refer to Figure 1 As shown, in this embodiment, the transfer mechanism 3 includes a suction cup. The advantage of the suction cup is that it can grasp a large area of ​​the surface of the battery cell 100. Compared with the gripper, this method can adapt to the battery cell 100 after the spacing has been adjusted without adjusting the spacing between each gripper in the gripper. This makes the operation more convenient, saves process steps, and helps to improve the transfer efficiency of the battery cell 100.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
