[0027] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0028] See also Figures 1 to 3 The battery cell continuous puncture device includes a seat body 1, two conveyor belts 2 and a puncture device 3; the two conveyor belts 2 are arranged on the seat body 1 at intervals along a first direction, the conveying directions of the two conveyor belts 2 are consistent, and the two conveyor belts 2 move synchronously, the two conveyor belts 2 are used to place the battery cell 200, and there is an escape space 21 between the two conveyor belts 2, and the first direction and the conveying direction are perpendicular to each other; and the puncture device 3 is arranged on the seat body 1 and located above the conveyor belts 2, the puncture device 3 has a puncture piece movably arranged along the vertical direction, and the puncture piece is arranged corresponding to the escape space 21, so that when the puncture piece moves vertically downward, the puncture piece is used to puncture the battery cell 200.

[0029] The utility model provides a battery cell continuous puncture device, wherein the two conveyor belts 2 are arranged on the seat body 1 at intervals along a first direction, the conveying directions of the two conveyor belts 2 are consistent, and the two conveyor belts 2 move synchronously, and there is an escape space 21 between the two conveyor belts 2. The puncture device 3 is arranged on the seat body 1 and is located above the conveyor belts 2. The puncture device 3 has a puncture piece that is movably arranged along a vertical direction, and the puncture piece is arranged corresponding to the escape space 21. When used, the battery cell 200 is placed on the two conveyor belts 2 so that the battery cell 200 needs to be punctured. The position corresponds to the avoidance space 21, and the battery cell 200 is transmitted to the bottom of the puncture piece through the two conveyor belts 2. Then the conveyor belt 2 stops, and the puncture piece moves vertically downward to puncture the battery cell 200. The avoidance space 21 can prevent the puncture piece from damaging the conveyor belt 2 after piercing the battery cell 200. After the puncture is completed, the conveyor belt 2 starts to transmit the next battery cell 200 to the bottom of the puncture piece. Multiple battery cells 200 can be transmitted on the conveyor belt 2, and the distance between adjacent battery cells 200 can be controlled, thereby shortening the production cycle and improving production efficiency.

[0030] There is no limitation on the driving mode of the two conveyor belts 2. The two conveyor belts 2 may be provided with independent driving mechanisms respectively, as long as the transmission speeds of the two conveyor belts are the same. Alternatively, a driving mechanism may be provided to drive the two conveyor belts 2 to move synchronously at the same time.

[0031] Furthermore, in order to prevent the battery cell 200 from moving during the puncture process, in this embodiment, the battery cell continuous puncture device further includes a clamping device 4, which is arranged on the seat 1 and located above the conveyor belt 2. The clamping device 4 is used to clamp the battery cell 200 when the battery cell 200 is conveyed to the bottom of the puncture device 3. In specific use, when the battery cell 200 is conveyed to the bottom of the puncture member, the conveyor belt 2 stops, and the clamping device 4 moves to clamp the battery cell 200 on the conveyor belt 2 to fix the battery cell 200. Then the puncture member punctures. After the puncture is completed, the clamping device 4 releases the battery cell 200, and the conveyor belt 2 starts to continue conveying. Such a setting can fix the battery cell 200 on the one hand, and on the other hand, when the puncture member is separated from the battery cell 200, the clamping device 4 can prevent the puncture member from taking the battery cell 200 away from the conveyor belt 2.

[0032] Furthermore, the clamping device 4 includes a pressing plate 41 and a first driving mechanism 42. The pressing plate 41 is movably arranged on the base body 1 along the vertical direction and is located above the conveyor belt 2, so that when the battery cell 200 is conveyed to the bottom of the puncture device 3, the pressing plate 41 moves vertically downward to press the battery cell 200 against the conveyor belt 2. The first driving mechanism 42 is connected to the pressing plate 41 and is used to drive the pressing plate 41 to move.

[0033] Furthermore, the specific form of the first driving mechanism 42 is not limited, and can be one of a pneumatic cylinder, a hydraulic cylinder, and an electric cylinder.

[0034] Furthermore, since the puncture site of the battery cell 200 is in the middle, in order to increase the contact area between the pressing plate 41 and the battery cell 200 and avoid the puncture member, in this embodiment, the pressing plate 41 is located directly below the puncture member, and the pressing plate 41 is provided with an avoidance hole corresponding to the puncture member. The diameter of the avoidance hole is larger than the diameter of the puncture member, and the puncture member can pass through the avoidance hole to puncture the battery cell 200. In this way, the contact area between the pressing plate 41 and the battery cell 200 can be increased, the pressing stability can be improved, and the puncture member can be avoided.

[0035] Furthermore, the puncture device 3 includes a puncture needle 31 and a second driving mechanism 32. The puncture needle 31 is movably arranged on the seat 1 along the vertical direction and is located above the avoidance space 21. The puncture needle 31 constitutes the puncture member. The second driving mechanism 32 is connected to the puncture needle 31 and is used to drive the puncture needle 31 to move.

[0036] Furthermore, the specific form of the second driving mechanism 32 is not limited, and can be one of a pneumatic cylinder, a hydraulic cylinder, and an electric cylinder.

[0037] Furthermore, the angle of the tip of the puncture needle 31 is one of 30°, 45° and 60°.

[0038] Furthermore, the battery cell continuous puncture device further includes a feeding conveyor belt 5, which is arranged in sequence with the conveyor belt 2 along the conveying direction, and is used to convey the battery cell 200 to the conveyor belt 2. The width of the feeding conveyor belt 5 is adapted to the sum of the width of the two conveyor belts 2 and the width of the avoidance space 21, so that the stability of the conveying of the battery cell 200 can be improved.

[0039] Furthermore, the battery cell continuous puncture device further comprises a discharge conveyor belt 6, and the conveyor belt 2 and the discharge conveyor belt 6 are arranged in sequence along the conveying direction. The width of the discharge conveyor belt 6 is adapted to the sum of the widths of the two conveyor belts 2 and the width of the avoidance space 21. By setting the feeding conveyor belt 5 and the discharge conveyor belt 6, the entire battery recycling production line can be matched, and the degree of automation is high.

[0040] Furthermore, the battery cell continuous puncture device further comprises a discharge cell, the two conveyor belts 2 are located in the discharge cell, and the discharge cell contains a solution for discharging the battery cell 200. The entire puncture process is performed in the solution.

[0041] Furthermore, in this embodiment, the battery cell continuous puncture device also includes a detection device, which is disposed on the seat body 1 and corresponding to the conveyor belt 2 , and is used to detect the position of the battery cell 200 .

[0042] Furthermore, the detection device is a position sensor, which can detect the position of the battery cell 200, thereby facilitating puncture by the puncture needle 31.
