[0034] Please refer to Figure 1 An embodiment of the present application provides a battery cell processing device, which includes a clamping device and a puncture device. The clamping device is used to clamp the battery cell of the scrapped lithium battery along a first direction X. The puncture device is used to puncture the explosion-proof valve of the battery cell.

[0035] Combination Figure 1 and Figure 2 The clamping device includes: a first driving member 110, a first transmission assembly, and two clamping members 130 arranged opposite to each other along the first direction X. The first transmission assembly includes a transmission unit corresponding to the clamping members 130, that is, the number of the transmission units is two. The first driving member 110 is used to drive the transmission unit to move along the second direction Y. The transmission unit and the corresponding clamping member 130, one of which is provided with a slide column 122, and the other is provided with a slide groove 131. The slide column 122 and the slide groove 131 are slidably matched, and the extension direction of the slide groove 131 is inclined to the first direction X and inclined to the second direction Y. In this way, during the movement of the transmission unit along the second direction Y, the relative movement of the slide column 122 in the slide groove 131 can drive the clamping member 130 to move along the first direction X. In actual use, the clamping device can be set on a supporting structure such as a support table.

[0036] Combination Figure 1 and Figure 3 The acupuncture device includes: a second driving member 210, a second transmission assembly 220 and a puncture needle assembly 230. The second driving member 210 is used to drive the second transmission assembly 220, so that the second transmission assembly 220 drives the puncture needle assembly 230 to move along the third direction Z to puncture the explosion-proof valve of the battery cell.

[0037] The first direction X, the second direction Y, and the third direction Z are perpendicular to each other. In actual use, the third direction Z is preferably a vertical direction, and the first direction X and the second direction Y are both in the horizontal direction.

[0038] When the above-mentioned battery cell processing equipment is in use, the battery cell (not shown) of the scrapped lithium battery is placed between two clamping members 130. The transmission unit is driven to move along the second direction Y by the first driving member 110. During the movement of the transmission unit along the second direction Y, the clamping member 130 is driven to move along the first direction X by the relative movement of the slide column 122 in the slide groove 131, so that the two clamping members 130 clamp the battery cell. Then, the second driving member 210 drives the second transmission assembly 220, so that the second transmission assembly 220 drives the puncture needle assembly 230 to move along the third direction Z to puncture the explosion-proof valve of the battery cell. In this way, the scrapped lithium battery can be discharged quickly, the discharge cycle can be accelerated, and the operation is convenient and the risk is low.

[0039] It can be understood that when the above-mentioned battery cell processing device is in use, the position of the puncture needle assembly 230 can be aligned with the explosion-proof valve along the third direction Z, so that the puncture needle assembly 230 can puncture the explosion-proof valve when moving along the third direction Z.

[0040] Combination Figure 1 and Figure 2 In one embodiment, the first transmission assembly includes a first motion conversion mechanism 123 and a connecting member 124. The input end of the first motion conversion mechanism 123 is connected to the output end of the first driving member 110, and the output end of the first motion conversion mechanism 123 is connected to the connecting member 124. The first driving member 110 is used to drive the first motion conversion mechanism 123 to move, and the first motion conversion mechanism 123 is used to convert the rotational motion output by the first driving member 110 into a translational motion along the second direction Y, thereby driving the connecting member 124 to translate along the second direction Y. In this way, it is convenient to drive the connecting member 124 to translate along the second direction Y through the rotational motion output by the first driving member 110. The first driving member 110 is, for example, a motor.

[0041] The two ends of the connecting member 124 along the first direction X are respectively connected to the two transmission units, so that the two transmission units can be connected simultaneously through one connecting member 124, and then the two clamping members 130 can be driven to move closer to or away from each other along the first direction Z simultaneously.

[0042] In one embodiment, the first motion conversion mechanism 123 is a ball screw mechanism.

[0043] In other embodiments, the first motion conversion mechanism is not limited to a ball screw mechanism, but may also be other conversion mechanisms.

[0044] Combination Figure 1 and Figure 2In one embodiment, the first transmission assembly includes two guide units, which are respectively located on both sides of the first motion conversion mechanism 123 along the first direction X. The guide unit includes a first slider 125 and a first slide rail 126, the first slider 125 is fixedly connected to the connecting member 124, and the first slider 125 and the first slide rail 126 are slidably matched along the second direction Y.

[0045] In actual use, the first slide rail 126 is fixed (can be fixed on a support structure such as a support table). Since the first slider 125 and the first slide rail 126 slide together along the second direction Y, the connecting member 124 can be guided to move accurately along the second direction Y, which is conducive to the clamping member 130 to move accurately along the first direction X.

[0046] Combination Figure 1 and Figure 2 In one embodiment, the transmission unit includes a second slider 1211, a second slide rail 1212, and a transmission rod 1213 extending along the second direction Y. The second slider 1211 is connected to an end of the transmission rod 1213 away from the first driving member 110. The second slider 1211 is provided with a slide post 122, and the second slider 1211 and the second slide rail 1212 are slidably matched along the second direction Y.

[0047] In actual use, the second slide rail 1212 is fixed (can be fixed on a support structure such as a support platform). When the transmission unit moves along the second direction Y, the transmission rod 1213 moves along the second direction Y, thereby driving the second slider 1211 to move along the second direction Y. Through the cooperation between the second slide rail 1212 and the second slider 1211, the second slider 1211 can be guided to move accurately along the second direction Y, and then the slide post 122 on the second slider 1211 can be moved accurately along the second direction Y.

[0048] In this embodiment, the clamping member 130 is provided with a slide groove 131. The slide post 122 on the second slider 1211 accurately moves along the second direction Y, which is conducive to the accurate and stable relative movement of the slide post 122 in the slide groove 131, and further facilitates the accurate and stable movement of the clamping member 130 along the first direction X.

[0049] In one embodiment, two ends of the connecting member 124 may be fixedly connected to the transmission rods 1213 of the two transmission units respectively.

[0050] In other embodiments, a sliding column may be provided on the clamping member, and a sliding groove may be provided on the transmission unit.

[0051] Combination Figure 1 and Figure 2In one embodiment, the clamping member 130 includes a clamping plate and a transmission plate 133, and the clamping plates of the two clamping members 130 are arranged opposite to each other along the first direction X. The transmission plate 133 is fixedly connected to one end of the clamping plate along the third direction Z and is perpendicular to each other. A slide groove 131 is provided on the transmission plate 133. By providing the transmission plate 133, it is convenient to open the slide groove 131, so as to facilitate the cooperation with the slide column 122.

[0052] In other embodiments, a sliding column may be provided on the transmission plate, and a sliding groove may be provided on the transmission unit.

[0053] Combination Figure 1 and Figure 2 In one embodiment, the first transmission assembly further includes a third slide rail 127, and a third slider 1331 is disposed on the transmission plate 133. The third slider 1331 is slidably connected to the third slide rail 127 along the first direction X.

[0054] In actual use, the third slide rail 127 is fixed (can be fixed on a support structure such as a support table). The third slider 1331 is slidably connected to the third slide rail 127 along the first direction X, so that the transmission plate 133 connected to the third slider 1331 can be accurately guided to move along the first direction X, that is, the clamping plate can be accurately moved along the first direction X, which is conducive to accurately and reliably clamping the battery cell.

[0055] Combination Figure 1 and Figure 2 In one embodiment, the clamping member 130 includes a clamping plate. The clamping plate includes a metal reinforcing plate 1321 and a non-metallic contact plate 1322 that is in close contact with the metal reinforcing plate 1321, and the non-metallic contact plate 1322 is located on a side of the metal reinforcing plate 1321 close to the battery cell. The non-metallic contact plate 1322 is fixedly connected to the metal reinforcing plate 1321. Since the non-metallic contact plate 1322 is located on a side of the metal reinforcing plate 1321 close to the battery cell, the clamping plate contacts the battery cell through the non-metallic contact plate 1322 when clamping the battery cell, thereby preventing the battery cell from short-circuiting.

[0056] In this embodiment, the metal reinforcing plate 1321 is made of metal material to provide clamping strength. The non-metallic contact plate 1322 can be made of non-metallic insulating material, such as plastic, to prevent the battery cell from contacting the metal reinforcing plate 1321 and causing a short circuit.

[0057] Combination Figure 1 and Figure 2 In one embodiment, the clamping member 130 includes a clamping plate, and a clamping groove 1323 is provided on one side of the clamping plate close to the battery cell and extending through the clamping groove 1323 along the third direction Z. The clamping grooves 1323 of the clamping plates of the two clamping members 130 are opposite to each other along the first direction X, and each clamping groove 1323 has two opposite and inclined side walls.

[0058] Specifically, the clamping plates of the two clamping members 130 have a plane on one side facing each other, which can be used to clamp a square battery cell with a plane surface. In this embodiment, the clamping grooves 1323 of the two clamping plates are opposite to each other along the first direction X, and each clamping groove 1323 has two opposite and inclined side walls, so that the two clamping grooves 1323 can be used to clamp a cylindrical battery cell, thereby improving the applicability diversity of the clamping device.

[0059] Combination Figure 1 and Figure 2 In one embodiment, the angle between the two opposite and inclined side walls of the clamping groove 1323 is an obtuse angle.

[0060] In one embodiment, the clamping device further includes a heightening block (not shown), which is located between the two clamping members 130 and is used to heighten the battery cell so that the height position of the battery cell can be flexibly adjusted.

[0061] Combination Figure 1 and Figure 2 In one embodiment, the clamping member 130 includes a clamping plate, and a pressure sensor 134 is provided on one side of the clamping plate close to the battery cell. The clamping force of the clamping plate clamping the battery cell can be detected by the pressure sensor 134. When the two clamping plates are close to each other to clamp the battery cell, the detection value of the pressure sensor 134 gradually increases, so that the clamping degree of the clamped battery cell can be judged according to the detection value of the pressure sensor 134, and then the first driving member 110 can be controlled to stop driving according to the detection result of the pressure sensor 134, so that the clamping plate stops at a suitable clamping position in a timely and accurate manner.

[0062] In one embodiment, the second transmission assembly 220 is a ball screw mechanism. The second driving member 210 is, for example, a motor. The output end of the second driving member 210 is connected to the input end of the second transmission assembly 220. The output end of the second transmission assembly 220 is connected to the puncture needle assembly 230. The second transmission assembly 220 converts the rotational motion of the second driving member 210 into a translational motion, thereby driving the puncture needle assembly 230 to move along the third direction Z.

[0063] In other embodiments, the second transmission assembly 220 is not limited to a ball screw structure, but may also be other structural forms.

[0064] Combination Figure 1 and Figure 3 In one embodiment, the cell processing device further includes a supporting device, an adjusting device and a mounting plate 500. The acupuncture device is disposed on the mounting plate 500. The adjusting device is disposed on the supporting device. The adjusting device includes an operating portion 410 and an adjusting component 420, wherein the operating portion 410 is used to operably drive the adjusting component 420 to move, so that the adjusting component 420 drives the mounting plate 500 to move along the third direction Z.

[0065] In actual use, the staff can manually operate the operating part 410 to drive the adjustment component 420 to move, so that the adjustment component 420 drives the mounting plate 500 to move along the third direction Z, and then drives the acupuncture device to move along the third direction Z, so that the position of the acupuncture device can be adjusted along the third direction Z, so that the position of the acupuncture device along the third direction Z can be flexibly adjusted, and thus can be suitable for battery cells of different specifications.

[0066] In other embodiments, the adjusting device may not be provided, and the acupuncture device may be directly provided on the supporting device.

[0067] Combination Figure 1 and Figure 3 In one embodiment, the adjusting device includes a locking mechanism 430, which is used to lock or release the operating part 410 to prevent or allow the operating part 410 to rotate around the axis of the second direction Y.

[0068] When the position of the acupuncture device along the third direction Z needs to be adjusted, the locking mechanism 430 releases the operating part 410, so that the operating part 410 can rotate around the axis of the second direction Y. After the position of the acupuncture device along the third direction Z is adjusted, the locking mechanism 430 can be used to lock the operating part 410 to prevent the operating part 410 from rotating, thereby ensuring that the position of the acupuncture device along the third direction Z is stable.

[0069] Combination Figure 1 and Figure 3 In one embodiment, the locking mechanism 430 includes an open ring 431 and a locking member 432. The open ring 431 is disposed on the supporting device. The open ring 431 is an annular structure with an opening, and the open ring 431 has two ends opposite to each other in the circumferential direction at its opening. The locking member 432 is used to lock the two ends so that the open ring 431 hugs the operating part 410. When the locking member 432 releases the two ends, the open ring 431 can open at the opening, thereby allowing the operating part 410 to rotate.

[0070] The locking member 432 is, for example, a threaded connector, which passes through one end of the opening of the open ring 431 and is screwed together with the other end of the opening to lock the two ends. When the threaded connector is rotated and separated from the other end of the opening, the two ends of the opening can be relatively opened.

[0071] Combination Figure 1 and Figure 3In one embodiment, the adjustment assembly 420 includes a first bevel gear 421 and a second bevel gear 422. The first bevel gear 421 is coaxially connected to the operating portion 410 and can rotate around the axis of the second direction Y. The second bevel gear 422 is meshed with the first bevel gear 421 and can rotate around the axis of the third direction Z. When the second bevel gear 422 rotates, it can drive the mounting plate 500 to move. By meshing the second bevel gear 422 with the first bevel gear 421, the rotation of the operating portion 410 around the axis of the second direction Y can be converted into the rotation around the axis of the third direction Z.

[0072] Combination Figure 1 and Figure 3 In one embodiment, the adjustment component 420 includes a second motion conversion mechanism 423. The input end of the second motion conversion mechanism 423 is connected to the second bevel gear 422, and the output end is connected to the mounting plate 500. The second motion conversion mechanism 423 is used to convert the rotational motion of the second bevel gear 422 into a translational motion along the third direction Z, thereby driving the mounting plate 500 to translate along the third direction Z. In this way, it is convenient to drive the acupuncture device to adjust the position along the third direction Z by rotating the operating part 410. The second motion conversion mechanism 423 is, for example, a ball screw mechanism.

[0073] Combination Figure 1 and Figure 3 In one embodiment, the supporting device includes a supporting seat 330 and a supporting plate 340 fixedly connected to the supporting seat 330 .

[0074] Combination Figure 1 and Figure 3 In one embodiment, a first limit block 310 and a second limit block 320 spaced apart along a third direction Z are provided on the support device (specifically, the support plate 340). A stop block 510 is provided on the mounting plate 500. Along the third direction Z, the stop block 510 is located between the first limit block 310 and the second limit block 320, so that the first limit block 310 and the second limit block 320 can limit the two extreme positions of the stop block 510 when it moves along the third direction Z, that is, limit the travel range of the stop block 510 when it moves along the third direction Z. In this way, the adjustment range of the acupuncture device when adjusting the position along the third direction Z can be limited to prevent the position along the third direction Z from being too far or too close to the battery cell.

[0075] Combination Figure 1 and Figure 3 In one embodiment, a fourth slide rail 341 is provided on the support device (specifically, the support plate 340), and a fourth slider 520 is provided on the mounting plate 500. The fourth slider 520 and the fourth slide rail 341 slide together along the third direction Z, thereby guiding the mounting plate 500 to move accurately and stably along the third direction Z, that is, guiding the acupuncture device to adjust its position accurately and stably along the third direction Z.

[0076] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
