[0030] In the prior art, during the battery recycling process, pulling the battery cover away from the housing and cutting the tabs are two separate steps, which to some extent affects the overall efficiency of battery disassembly. The battery tab removal device provided in this application combines the two steps of pulling the battery cover away and cutting the tabs, effectively improving the overall efficiency of battery disassembly.

[0031] The present embodiment provides a battery tab removal device. Referring to Figures 1 to 4, the battery tab removal device includes a clamping assembly 1, a cutting assembly 2, and a linkage assembly, wherein the clamping assembly 1 is configured to clamp the battery cover 41; the cutting assembly 2 includes a cutting base 21, a rocker 22, and a cutter 23, which are sequentially connected, and the cutter 23 is swingably disposed on the cutting base 21 via the rocker 22; the linkage assembly includes a first linkage member 31, a second linkage member 32, a third linkage member 33, and a rack 34, wherein the rack 34 is disposed on the clamping assembly 1, the cutting base 21 is fixedly disposed, and the first linkage member 31 is rotatably disposed through the cutting base 21. The first linkage 31 is provided with a first spiral tooth segment 311 and a second spiral tooth segment 312, the second linkage 32 is connected to the rocker arm 22, the second linkage 32 is screwed to the first spiral tooth segment 311, and the two ends of the third linkage 33 are respectively engaged with the second spiral tooth segment 312 and the rack 34; the first linkage 31 rotates relative to the second linkage 32 about the first rotation direction, and can drive the clamping assembly 1 to move in the first moving direction through the third linkage 33, and at the same time can drive the second linkage 32 to move relative to the cutting substrate 21 in the first moving direction and drive the rocker arm 22 to swing so that the cutter 23 cuts the battery tab 43.

[0032] In the figure, direction a is the first rotation direction; direction b1 is the first movement direction, which is also the pulling direction that drives the cover 41 away from the shell 42; direction b2 is the second movement direction, which is also the direction in which the second linkage member 32 moves away from the cutting substrate 21; and direction c is the downward swinging direction of the cutter 23.

[0033] For example, the beneficial effects of the device are described below in conjunction with the use process of the battery tab removal device.

[0034] When the battery tab removal device is used to remove the tab 43, the cover 41 of the battery to be removed is clamped by the clamping assembly 1, and then the first linkage 31 is controlled to rotate relative to the second linkage 32 around the first rotation direction, that is, the direction a in the figure. Since the two ends of the third linkage 33 are respectively engaged with the second spiral tooth segment 312 and the rack 34, the clamping assembly 1 holding the cover 41 is driven to move in the first direction, that is, the direction in which the cover 41 is pulled away from the shell 42, that is, the direction b in the figure, to pull the cover 41 away from the shell 42, thereby exposing the tab 43 connected between the cover 41 and the shell 42. At the same time, because the second linkage member 32 is slidably mounted on the rocker 22 and threadedly connected to the first helical tooth segment 311, the rotation of the first linkage member 31 relative to the second linkage member 32 about the first rotation direction can drive the second linkage member 32 to move relative to the cutting substrate 21 in the second movement direction, i.e., direction c in the figure, thereby increasing the spacing between the second linkage member 32 and the first linkage member 31. Under the action of the second linkage member 32, the rocker 22 swings downward in direction c, and then the rocker 22 aligns with the tab 43 and cuts the tab 43. In the above process, the removal of the cover plate 41 and the removal of the tab 43 can be carried out in conjunction, thereby effectively improving the overall efficiency of the battery disassembly operation.

[0035] A first end of the swing rod 22 is hinged to the cutting base plate 21 via a hinge shaft (not shown), and a second end of the swing rod 22 is fixedly connected to the cutter 23 .

[0036] In this embodiment, the first end of the third linkage member 33 is provided with a first gear 331 that meshes with the second helical tooth segment 312, and the second end of the third linkage member 33 is provided with a second gear 332 that meshes with the rack 34. The first gear 331 and the second helical tooth segment 312 form a worm gear structure at the first end of the third linkage member 33, and the second gear 332 and the rack 34 form a gear-rack structure at the second end of the third linkage member 33. When the first linkage member 31 rotates about the first rotation direction, the meshing between the second helical tooth segment 312 and the first gear 331 causes the third linkage member 33 to rotate, driving the second gear 332 to rotate. Furthermore, the meshing between the second gear 332 and the rack 34 drives the clamping assembly 1 to move along the first movement direction.

[0037] The first linkage member 31 is provided with a smooth section 313 between the first helical tooth segment 311 and the second helical tooth segment 312. The cutting substrate 21 is provided with a rotation hole 211, and the smooth section 313 is configured to rotate within the rotation hole 211. The provision of the smooth section 313 on the first linkage member 31 ensures reliable and smooth rotational engagement with the rotation hole 211, thereby ensuring that the cutting substrate 21 can rotate smoothly relative to the first linkage member 31.

[0038] In some optional embodiments, a bearing is provided between the cutting substrate 21 and the smooth section 313, the outer ring of the bearing is fixed to the cutting substrate 21, and the inner ring of the bearing is fixed to the smooth section 313. The cutting substrate 21 can also achieve a rotational connection with the smooth section 313 through the bearing.

[0039] The second linkage member 32 includes a first joint 321 and a second joint 322. The second joint 322 is connected to one side of the first joint 321 via a connecting rod 323. The first joint 321 is provided with a first screw hole 3211. The first joint 321 is sleeved on the first helical tooth segment 311 through the first screw hole 3211 and is screwed to the first helical tooth segment 311. A screw-nut structure can be formed between the first screw hole 3211 and the first helical tooth segment 311. When the first linkage member 31 rotates about the first rotation direction, the first screw hole 3211 and the first helical tooth segment 311 engage with each other, allowing the first linkage member 31 to move relative to the second linkage member 32 along the first movement direction. This, in turn, drives the swing arm 22 to swing via the connecting rod 323 and the second joint 322, so that the cutter 23 cuts the battery tab 43.

[0040] Optionally, as shown in FIG4 , the first joint 321 is fixedly connected to the first end of the connecting rod 323, and the second joint 322 is rotatably connected to the second end of the connecting rod 323. The second joint 322 defines a sliding hole 3221, through which the second joint 322 is slidably mounted on the rocker arm 22. As the first linkage member 31 moves relative to the second linkage member 32 in the first movement direction, the first joint 321 drives the rocker arm 22 to swing downward via the connecting rod 323 and the second joint 322. During this process, the second joint 322 can adaptively rotate relative to the connecting rod 323. This arrangement allows the size of the sliding hole 3221 in the second joint 322 to adapt to the radial size of the rocker arm 22. As the second joint 322 slides relative to the rocker arm 22, the axes of the two joints can be collinear, thereby making the rocker arm 22 more stable in its swing.

[0041] Optionally, as shown in FIG5 , the first joint 321 is rotatably connected to the first end of the connecting rod 323, the second joint 322 is rotatably connected to the second end of the connecting rod 323, and the second joint 322 is fixedly connected to the swing arm 22. In this embodiment, no sliding hole is required; the second joint 322 is directly fixed to the swing arm 22. During movement of the first linkage member 31 relative to the second linkage member 32 in the first movement direction, the first joint 321 and the second joint 322 simultaneously rotate relative to the connecting rod 323, causing the second joint 322 to drive the swing arm 22 to swing downward. This structure is similar to the retractable structure of a camera tripod and can reliably and effectively achieve the downward swing of the swing arm 22 to allow the cutter 23 to cut the battery tab 43.

[0042] In this embodiment, the cutting substrate 21 is provided with a rocker 22 on both sides of the clamping assembly 1. A first joint 321 is provided with multiple second joints 322 corresponding one-to-one with the rocker 22. Referring to the accompanying drawings, the upper and lower ends of the first joint 321 are connected to the second joints 322 via connecting rods 323. A rocker 22 is provided at each of the upper and lower ends of the cutting substrate 21, and the two rocker 22s are respectively penetrated by two sliding holes 3221 for the second joints 322. This arrangement enables cutting of the tab 43 from both the upper and lower sides, further improving the reliability and effectiveness of the tab 43 cutting process.

[0043] The linkage assembly also includes a first drive motor 35, the output shaft of which is fixedly connected to the first linkage member 31. The output shaft of the first drive motor 35 can be fixedly connected to the first linkage member 31 via a coupling. The provision of the first drive motor 35 enables automatic rotation of the first linkage member 31, improving the overall automation level of the device.

[0044] Continuing with Figures 1 to 3, the clamping assembly 1 includes a clamping base 11 and a pair of clamping plates 12 disposed on the clamping base 11. The two clamping plates 12 are configured to jointly clamp the battery, and the rack 34 is disposed on the clamping base 11. The two clamping plates 12 can move closer to or farther from each other relative to the clamping base 11. When the two clamping plates 12 are close to each other, they can reliably clamp and secure the battery cover 41.

[0045] The clamping assembly 1 also includes a clamping transmission assembly 13. A slide 112 is provided on the clamping base 11. Each clamping plate 12 is provided with a sliding head 121 that slides with the slide 112. The clamping transmission assembly 13 can drive the two clamping plates 12 to move closer together to clamp the battery; or move away from each other to release the battery. For example, the clamping transmission assembly 13 can drive the sliding head 121 to slide on the slide 112, so that the two clamping plates 12 move closer together and clamp the battery, or move away from each other to release the battery. By providing the slide 112 and the sliding head 121, the movement direction of the clamping plate 12 relative to the clamping base 11 can be strictly limited, further improving the reliability of the clamping of the two clamping plates 12.

[0046] In this embodiment, the clamping transmission assembly 13 includes a driven bevel gear 131, a driving bevel gear 132, and a screw 133. The screw 133, the driven bevel gear 131, and the sliding head 121 are arranged in a one-to-one correspondence. The sliding head 121 is screwed to the first end of the screw 133, and the second end of the screw 133 is connected to the driven bevel gear 131. The driving bevel gear 132 is simultaneously meshed with the two driven bevel gears 131. In this embodiment, by driving the driving bevel gear 132 to rotate, the two driven bevel gears 131 meshed therewith can be driven to rotate, thereby driving the screw 133 connected to the driven bevel gears 131 to rotate. Since the sliding head 121 is sleeved on the screw 133 and screwed to the screw 133, and the sliding head 121 is also slidably connected to the slide 112, the rotation of the screw 133 can drive the sliding head 121 to slide on the slide 112, thereby achieving the movement drive of the clamping plate 12.

[0047] The sliding head 121 defines a third threaded hole 1211, through which the sliding head 121 is sleeved onto the screw rod 133 and threadedly engaged with the screw rod 133. The screw rod 133, through the third threaded hole 1211, and the sliding head 121 form a screw-nut structure. With the threads of the third threaded hole 1211 and the screw rod 133 engaged, the screw rod 133 rotates, driving the sliding head 121 to slide on the slideway 112.

[0048] The clamping assembly 1 also includes a second drive motor 14, and a driving bevel gear 132 is fixedly mounted on the output shaft of the second drive motor 14. The driving bevel gear 132 is fixedly mounted on the output shaft of the second drive motor 14 via a key connection. The provision of the second drive motor 14 enables automatic rotation of the driving bevel gear 132, further enhancing the overall automation level of the device.

[0049] When using the battery tab removal device provided by the present application, the battery cover is clamped on both sides of the long side by a clamping assembly, thereby clamping the battery cover. The first linkage is then controlled to rotate relative to the second linkage about a first rotational direction. Since the two ends of the third linkage are respectively engaged with the second helical tooth segment and the rack, the clamping assembly for clamping the cover is driven to move in a first movement direction, i.e., the direction in which the battery cover is pulled away from the housing, thereby pulling the cover away from the housing and exposing the tab connected between the cover and the housing. At the same time, since the second linkage is slidably mounted on the swing arm and screwed to the first helical tooth segment, the rotation of the first linkage relative to the second linkage about the first rotational direction can drive the second linkage to move relative to the cutting base in the second movement direction, thereby increasing the distance between the second linkage and the first linkage. Under the action of the second linkage, the swing arm swings downward, aligning with the tab and cutting the tab. The above process achieves the purpose of pulling the cover away from the housing while cutting the tab, so that the pulling of the cover and the removal of the tab can be carried out in a coordinated manner, thereby effectively improving the overall efficiency of the battery disassembly operation.

[0050] Exemplarily, the working process of the battery tab removal device is described below.

[0051] When the tab 43 needs to be removed, the second drive motor 14 drives the active bevel gear 132 to rotate, and the two driven bevel gears 131 meshing with the active bevel gear 132 rotate, driving the two screws 133 to rotate, so that the two sliding heads 121 move synchronously in opposite directions, and then the two clamping plates 12 move toward the two sides of the long side of the cover plate 41, clamping the two sides of the long side of the cover plate 41.

[0052] After clamping the cover plate 41, the first drive motor 35 drives the first linkage 31 to rotate, the second helical tooth segment 312 drives the first gear 331 to rotate, and drives the second gear 332 of the third linkage 33 to rotate. Under the engagement of the second gear 332 and the rack 34, the clamping substrate 11 is moved in the direction away from the battery shell 42, thereby moving the clamping plate 12 that clamps the cover plate 41 in the direction away from the shell 42, pulling the previously cut cover plate 41 away from the shell 42 and exposing the tab 43.

[0053] At the same time, the first linkage member 31 rotates, and the second linkage member 32 moves as a whole toward one end of the battery under the threaded cooperation of the first spiral tooth segment 311 and the first screw hole 3211 of the first joint 321, so that the two relatively arranged rocker arms 22 located at one end of the tab 43 rotate along the hinge with the cutting base plate 21, causing the two rocker arms 22 to rotate toward the tab 43. The two cutters 23 at the ends of the rocker arms 22 simultaneously move toward the tab 43 and cut the tab 43, thereby cutting off the tab 43. This achieves the purpose of pulling the cover plate 41 away from the housing 42 while simultaneously cutting off the tab 43. In the above process, the pulling away of the cover plate 41 and the cutting off of the tab 43 can be carried out in conjunction, thereby effectively improving the overall efficiency of the battery disassembly operation.

[0054] To sum up, the battery tab cutting device provided in this embodiment is configured by setting a linkage assembly, wherein the first linkage member 31 rotates relative to the second linkage member 32 around a first rotation direction, and the second spiral tooth segment 312 is engaged with the first gear 331 to rotate the third linkage member 33, thereby driving the second gear 332 to rotate, and the engagement between the second gear 332 and the rack 34 drives the clamping assembly 1 to move along the first moving direction, thereby pulling the cover plate 41 away from the shell 42 and exposing the tab 43 connected between the cover plate 41 and the shell 42. At the same time, the second linkage member 32 is slidably mounted on the rocker arm 22 and screwed to the first spiral tooth segment 311. The first linkage member 31 rotates relative to the second linkage member 32 around the first rotation direction to drive the second linkage member 32 to move relative to the cutting substrate 21 in the second moving direction. Under the action of the second linkage member 32, the rocker arm 22 swings downward, and then the rocker arm 22 aligns with the tab 43 and cuts the tab 43. During the whole process, the pulling away of the battery cover 41 and the cutting off of the tab 43 can be carried out in conjunction, thereby effectively improving the overall operation efficiency of the battery disassembly.
