If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0029] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0030] Please refer to Figures 1 to 4 , Figure 1 The battery cell shell insertion device in one embodiment of the utility model is shown, comprising: a shell insertion carrier 2 and a pushing device 5. Figure 2The shell insertion carrier 2 is shown, and the shell insertion carrier 2 includes a clamping mechanism 21, a positioning mechanism 22 and a shell insertion mechanism 23. The clamping mechanism 21 is used to clamp the shell 7. The positioning mechanism 22 is used to position the battery cell 6 so that the axis of the shell 7 and the axis of the battery cell 6 are collinear. The shell insertion mechanism 23 includes a first guide 231 and a second guide 232. The shell insertion mechanism 23 includes an open state and a closed state. When the shell insertion mechanism 23 is in the closed state, the first guide 231 and the second guide 232 jointly limit the through hole 233, the axis of the through hole 233 is collinear with the axis of the battery cell 6, the diameter of the end of the through hole 233 close to the shell 7 is not less than the diameter of the battery cell 6 and not greater than the diameter of the shell 7, and the diameter of the end of the through hole 233 close to the battery cell 6 is greater than the diameter of the end of the through hole 233 close to the shell 7. When the shell insertion mechanism 23 is in the open state, the first guide 231 and the second guide 232 are away from each other. The pushing device 5 is used to push the battery cell 6 from the positioning mechanism 22 into the shell 7. In the specific implementation process, the battery cell 6 and the shell 7 will be respectively conveyed to the first feeding device 3 and the second feeding device 4 by two conveyor belts. The first feeding device 3 places the battery cell 6 on the positioning mechanism 22. The specific positioning mechanism 22 is a groove with multiple abutment surfaces, and the battery cell 6 can slide along the groove on the positioning mechanism 22. The second feeding device 4 places the shell 7 on the clamping mechanism 21, and the clamping mechanism 21 positions and clamps the shell 7. The positioning mechanism 22 positions the battery cell 6 so that the axis of the shell 7 fixed by the clamping mechanism 21 coincides with the axial direction of the battery cell 6. Thereby, the pushing device 5 can better enter when pushing the battery cell 6 into the shell 7. At the same time, a shell insertion mechanism 23 is provided, and the shell insertion mechanism 23 includes an expanded state and a closed state. In the closed state, a through hole 233 with a larger diameter at one end and a smaller diameter at the other end is formed, so that the battery cell 6 can easily enter the through hole 233 from the end with a larger diameter of the through hole 233, and enter the shell 7 from the end with a smaller diameter of the through hole 233 through the guidance of the through hole 233, so that the battery cell 6 is faster and more convenient in the shell insertion process. After one end of the battery cell 6 enters the shell 7, the shell insertion mechanism 23 switches to an open state to avoid hindering the movement of the current collecting plate, cover plate, etc. on the battery cell 6, so that the battery cell 6 can completely enter the shell 7, thereby achieving the effect of quickly and accurately placing the battery cell 6 into the shell 7.

[0031] Specifically, the battery cell 6 includes a body and a cover plate, and the body of the battery cell 6 includes a first end and a second end, wherein the first end is an end close to the shell 7, and the cover plate is welded to the second end. When the first end passes through the through hole 233 defined by the first guide 231 and the second guide 232, the through hole 233 guides the battery cell 6 so that the first end of the battery cell 6 enters the shell 7. Since the battery cell 6 needs to be introduced into the shell 7, the gap between the battery cell 6 and the through hole 233 is small, so when the second end passes through the through hole 233, the cover plate will abut against the first guide 231 and the second guide 232, so that the second end cannot pass through the shell entry mechanism 23 and cannot enter the shell 7. Therefore, the shell entry mechanism 23 switches to an open state after the first end is introduced into the shell 7, so that the cover plate can pass through the shell entry mechanism, so that the battery cell 6 can completely enter the shell 7.

[0032] For further information, please refer to Figures 1 to 6 The battery cell shelling equipment also includes a conveyor belt 1, a first feeding device 3 and a second feeding device 4, and the shelling carrier 2 is arranged on the conveyor belt 1. The first feeding device 3 is used to place the battery cell 6 on the positioning mechanism 22. The second feeding device 4 is used to place the shell 7 on the clamping mechanism 21. After the first feeding device 3 and the second feeding device 4 are used for feeding, the conveyor belt 1 transports the shelling carrier 2, and transports the shelling carrier 2 to the position of the pushing device 5 to push the battery cell 6 into the shell 7. After the shelling is completed, the conveyor belt 1 transports the pushing device 5 together with the battery cell 6 and the shell 7 after shelling to the next station. Thereby, the efficiency of shelling the battery cell 6 is greatly improved.

[0033] Reference Figure 3 The positioning mechanism 22 includes a first abutting plane 221 and a second abutting plane 222, both of which abut against and are tangent to the side of the battery cell 6. Specifically, the first abutting plane and the second abutting plane are in a V-shaped structure, and the first abutting plane and the second abutting plane form a groove to position the battery cell 6 and also form a slide groove, so that the battery cell 6 can slide along the slide groove, and the battery cell 6 is pushed by the pushing device 5 to pass through the shell carrier 2 and enter the shell 7.

[0034] Reference Figure 2 The clamping mechanism 21 includes a positioning member 211 and a fixing member 212. The positioning member 211 includes a third abutting plane 2111 and a fourth abutting plane 2112. The third abutting plane 2111 and the fourth abutting plane 2112 are both abutted and tangent to the side of the shell 7. The fixing member 212 is used to fix the shell 7 on the positioning member 211. In order to prevent the shell 7 from moving during the process of the battery cell 6 being put into the shell, the fixing member 212 is used to fix the shell 7 after it can be placed in the V-shaped groove for positioning.

[0035] Reference Figure 2The fixing member 212 includes a first clamping plate 2121, a second clamping plate 2122 and a first driving member 2123. The first driving member 2123 is used to drive the first clamping plate 2121 and the second clamping plate 2122 to clamp or release each other. When the first clamping plate 2121 and the second clamping plate 2122 are clamped together, the shell 7 is fixed on the positioning member 211. The first clamping plate 2121 and the second clamping plate 2122 clamp the shell 7, on the one hand, so that the shell 7 is stably fixed on the positioning member 211, on the other hand, the fixing of the fixing member 212 to the shell 7 can be easily released, which makes it more convenient to take and put the shell 7. Furthermore, the clamping surfaces of the first clamping plate 2121 and the second clamping plate 2122 for clamping the shell 7 are arc surfaces that match the side surfaces of the shell 7, thereby increasing the contact area between the first clamping plate 2121, the second clamping plate 2122 and the shell 7, and avoiding deformation of the shell 7 caused by clamping.

[0036] The clamping mechanism 21 further includes a baffle 213, which is disposed on the positioning member 211 and abuts against an end of the shell 7 away from the battery cell 6. The shell 7 is abutted against the end away from the battery cell 6 to prevent the shell 7 from moving when the battery cell 6 is inserted into the shell.

[0037] Reference Figure 6 The first feeding device 3 includes a first drive group 31, a second drive group 32, a third drive group 33 and a clamp 34. The first drive group 31 drives the second drive group 32 to move in a first direction, and the first direction is parallel to the axial direction of the battery cell 6. The second drive group 32 drives the third drive group 33 to move in a second direction. The third drive group 33 drives the clamp 34 to move in a third direction, and the third direction is a vertical direction. The first direction, the second direction and the third direction are perpendicular to each other. The clamp 34 is used to clamp the battery cell 6. Through the cooperation between multiple linear modules, the battery cell 6 can be stably and accurately placed on the positioning mechanism 22 in the shell carrier 2. Furthermore, multiple clamps 34 can be set to clamp multiple battery cells 6 at the same time, and placing multiple battery cells 6 into the positioning mechanism 22 at the same time greatly improves the efficiency of the battery cell 6 entering the shell.

[0038] Reference Figure 5 The pushing device 5 includes a second driving member 51 and a pressing plate 52. The pressing plate 52 is connected to the movable end of the second driving member 51. The second driving member 51 drives the pressing plate 52 to move along the axial direction of the battery cell 6. The pressing plate 52 abuts against one end of the battery cell 6 away from the shell 7. The pressing plate 52 is provided to increase the contact area between the pushing device 5 and the battery cell 6. At the same time, multiple battery cells 6 can be pushed, which protects the battery cells 6 from damage by the pushing device 5 and improves the efficiency of the battery cells 6 entering the shell. Specifically, one pressing plate 52 can be used to push multiple battery cells 6 into the shell 7, and multiple pressing plates 52 can be used to push the battery cells into the shell in a one-to-one correspondence with multiple battery cells 6.

[0039] The shell entry mechanism 23 also includes a third driving member, which is used to drive the shell entry mechanism 23 to switch between an open state and a closed state. The shell entry mechanism 23 also includes a sensing device, which is used to sense the position of the battery cell 6 close to the shell 7. After the end of the battery cell 6 close to the shell 7 enters the shell 7, the third driving member drives the shell entry mechanism 23 to switch to the open state. After a part of the battery cell 6 enters the shell 7, the battery cell 6 can enter the shell 7 smoothly without the need for the shell entry mechanism 23 to guide and restrict it. In order to avoid the current collecting plate or cover plate at the end of the battery cell 6 away from the shell 7 from colliding with the shell entry mechanism 23, it is necessary to switch the shell entry mechanism 23 to the open state after a part of the battery cell 6 enters the shell 7.

[0040] Reference Figure 4 The shell-entry mechanism 23 further includes a guide rail 234, on which the first guide member 231 and the second guide member 232 are slidably disposed, and the third driving member is a linear motor, which drives the first guide member 231 and the second guide member 232 to slide on the guide rail 234. Specifically, when the first guide member 231 and the second guide member 232 are close to each other and abut against each other, the shell-entry mechanism 23 is in a closed state. When the first guide member 231 and the second guide member 232 are away from each other and allow the collector plate and the cover plate welded on the end of the battery cell 6 away from the shell 7 to pass, the shell-entry mechanism 23 is in an open state.

[0041] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
