[0002] Battery disassembly is essential during battery development. In existing technologies, most disassembly is done manually with pliers. For batteries made of hard plastic, such as steel-cased lithium batteries, the disassembly process is often laborious, inefficient, and prone to finger scratches. This utility model provides a lithium battery case cutter that effectively addresses this problem, improving disassembly efficiency and ensuring personal safety. Utility Model Content

[0003] In order to overcome the above shortcomings, the purpose of the present invention is to provide a lithium battery shell cutter to solve the problem of difficulty in manually disassembling batteries proposed in the above background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is a lithium battery shell cutting machine, including a base, a clamping device and a cutting mechanism, wherein:

[0005] The clamping device and the cutting mechanism are spaced apart along the first direction at the top of the base along the second direction.

[0006] The clamping device includes an air-filled clamping mechanism, and a clamping opening is provided on a side of the air-filled clamping mechanism facing the cutting mechanism along the first direction, for placing a lithium battery and injecting compressed air to clamp the lithium battery.

[0007] The cutting mechanism includes a rotating shaft, a grinding wheel and a drive assembly. The rotating shaft extends along the first direction. The grinding wheel is arranged on the side of the rotating shaft close to the clamping port. The drive assembly is used to drive the rotating shaft to drive the grinding wheel to rotate so as to cut the outer shell of the lithium battery.

[0008] The lithium battery shell cutter provided by this utility model utilizes an inflatable clamping mechanism that clamps the lithium battery by injecting compressed air. This allows for simple operation, reducing the complexity of manual operation. The inflatable clamping mechanism evenly clamps the lithium battery, ensuring stability during the cutting process and reducing cutting errors caused by unstable clamping. The lithium battery shell is cut using a rotating grinding wheel. The grinding wheel is positioned on the side of the rotating shaft near the clamping opening, bringing the cutting action closer to the lithium battery, reducing the distance the grinding wheel must travel, and improving cutting efficiency.

[0009] In some embodiments, the clamping device further comprises a rotating assembly. A synchronous shaft is provided on a side of the pneumatic clamping mechanism away from the cutting mechanism along the first direction. The rotating assembly comprises a first stepper motor and a first synchronous belt assembly, the first synchronous belt assembly being wound between the drive end of the first stepper motor and the synchronous shaft, and configured to drive the synchronous shaft and the lithium battery in the clamping port to rotate via the first stepper motor.

[0010] The above technical solution allows the rotating assembly to maintain stability during the cutting process, reducing cutting errors caused by unstable lithium battery position, thereby improving cutting quality. Furthermore, the rotating assembly allows the cutting process to proceed continuously, eliminating the need for frequent manual adjustments to the lithium battery position, thereby improving production efficiency.

[0011] In some embodiments, the driving assembly includes a second stepper motor and a second synchronous belt assembly, and the second synchronous belt assembly is arranged between the side of the rotating shaft away from the clamping port and the driving end of the second stepper motor, and is used to drive the rotating shaft to rotate through the second stepper motor.

[0012] With the above technical solution, the stepper motor provides precise control capabilities that can adapt to different cutting speeds and load requirements, allowing the equipment to process lithium batteries of different types and sizes.

[0013] In some embodiments, the cutting mechanism further includes a moving assembly. The moving assembly includes a linear guide and a servo motor. The linear guide extends along a third direction, has a slidably engaged mounting plate at its top, and is connected to the base at its bottom. The drive assembly is supported by the mounting plate. The servo motor is disposed on one side of the linear guide along the first direction and is configured to drive the mounting plate to move along the third direction.

[0014] Using this technical solution, a linear guide adjusts the distance between the grinding wheel and the clamping opening in the third direction. The smaller the distance, the deeper the lithium battery cutting depth. The servo motor provides high-precision positioning, ensuring that the cutting mechanism moves precisely to the desired position for cutting. The linear guide provides a stable motion path, ensuring the stability of the cutting mechanism during movement, helping to reduce friction and wear on the moving components during movement, and extending the service life of the equipment.

[0015] In some embodiments, the drive assembly further includes a bearing holder extending along the second direction, with a bottom portion fixed to the mounting plate and a top portion rotatably connected to the rotating shaft for supporting the rotating shaft.

[0016] By adopting the above technical solution, the bearing retainer can effectively support the rotating shaft, reduce the bending and vibration of the shaft, and thus improve the stability and accuracy of the rotation.

[0017] In some embodiments, the lithium battery shell cutting machine further includes a dust collecting box, which is disposed between the clamping device and the cutting mechanism along the first direction and correspondingly disposed below the clamping opening and the grinding wheel to collect cutting dust.

[0018] In some embodiments, the lithium battery shell cutting machine further includes a housing. The housing is disposed over the clamping device and the cutting mechanism and is connected to the base. The housing includes a protective cover that is detachably connected to the housing and is disposed corresponding to the dust collection box.

It also protects the interior of the machine from dust and dirt that could affect performance. The protective cover, positioned in conjunction with the dust collection box, effectively collects dust and debris generated during the cutting process, improving dust collection efficiency and reducing pollution to the work environment.

[0020] In some embodiments, a first speed regulator, a second speed regulator, and a control screen are provided on one side of the hood along the third direction. The first speed regulator is electrically connected to the first stepper motor for regulating the first stepper motor. The second speed regulator is electrically connected to the second stepper motor for regulating the second stepper motor. The control screen is connected to the first speed regulator, the second speed regulator, and the servo motor.

[0021] Using this technical solution, the control screen is used to adjust and display the motor parameters. The cutting depth is controlled by the servo motor, and the value can be set on the touch screen. After the servo motor has traveled the set distance, it returns to its original position.

[0022] In some embodiments, the lithium battery shell cutting machine further includes an electrical cabinet. The electrical cabinet is disposed on one side of the linear guide rail along the third direction and is connected to the first speed regulator, the second speed regulator, the servo motor, and the control panel.

[0030] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

Figure 1 ; Figure 3 The three-dimensional diagram of a lithium battery shell cutting machine 1 provided by the embodiment of the present invention is shown. Figure 2 .

[0032] like Figures 1 to 3 As shown, the technical solution provided by the present application is a lithium battery shell cutting machine 1, comprising a base 2, a clamping device 3 and a cutting mechanism 4, wherein: the clamping device 3 and the cutting mechanism 4 are arranged along a first direction ( Figure 3 X direction) are arranged at intervals on the base 2 along the second direction ( Figure 3The clamping device 3 includes an inflatable clamping mechanism 20. A clamping opening 200 is provided on the side of the inflatable clamping mechanism 20 facing the cutting mechanism 4 along the first direction. This opening is used to place the lithium battery 8 and inject compressed air to clamp the lithium battery 8. The cutting mechanism 4 includes a rotating shaft 40, a grinding wheel 41, and a drive assembly 42. The rotating shaft 40 extends along the first direction. The grinding wheel 41 is located on the side of the rotating shaft 40 near the clamping opening 200. The drive assembly 42 is used to drive the rotating shaft 40 to rotate the grinding wheel 41 to cut the outer shell of the lithium battery 8.

[0033] The lithium battery shell cutting machine 1 provided in this application utilizes an inflatable clamping mechanism 20 that clamps the lithium battery 8 by injecting compressed air. This allows for simple operation and reduces the complexity of manual operation. The inflatable clamping mechanism 20 can evenly clamp the lithium battery 8, ensuring the stability of the lithium battery 8 during the cutting process and reducing cutting errors caused by unstable clamping. The outer shell of the lithium battery 8 (including steel-shell lithium batteries 8) is cut by rotating a grinding wheel 41. The grinding wheel 41 is located on the side of the rotating shaft 40 near the clamping opening 200, bringing the cutting action closer to the lithium battery 8, reducing the distance required for the grinding wheel 41 to move, and improving cutting efficiency.

[0034] In some embodiments, reference Figures 1 to 3 The clamping device 3 further includes a rotating assembly 21. A synchronous shaft 201 is provided on a side of the pneumatic clamping mechanism 20 that is located in a first direction away from the cutting mechanism 4. The rotating assembly 21 includes a first stepper motor 210 and a first synchronous belt assembly 211. The first synchronous belt assembly 211 is wound between the driving end of the first stepper motor 210 and the synchronous shaft 201, and is used to drive the synchronous shaft 201 and the lithium battery 8 in the clamping port 200 to rotate via the first stepper motor 210.

[0035] For example, the rotating assembly 21 allows the lithium battery 8 to remain stable during the cutting process, reducing cutting errors caused by the unstable position of the lithium battery 8, thereby improving cutting quality. The rotating assembly 21 also allows the cutting process to be carried out continuously, eliminating the need for frequent manual adjustment of the position of the lithium battery 8, thereby improving production efficiency.

[0036] In some embodiments, reference Figures 1 to 3 The driving assembly 42 includes a second stepper motor 420 and a second synchronous belt assembly 421. The second synchronous belt assembly 421 is arranged between the side of the rotating shaft 40 away from the clamping port 200 and the driving end of the second stepper motor 420, and is used to drive the rotating shaft 40 to rotate through the second stepper motor 420.

[0037] Illustratively, the stepper motor provides precise control capabilities that can adapt to different cutting speeds and load requirements, allowing the device to process lithium batteries 8 of different types and sizes.

[0038] In some embodiments, reference Figures 1 to 3 The cutting mechanism 4 further includes a moving assembly 44. The moving assembly 44 includes a linear guide rail 440 and a servo motor 441. The linear guide rail 440 moves in the third direction ( Figure 3 The linear guide rail 440 extends in the first direction (shown in the Y direction), has a slidably engaged mounting plate 45 at the top, is connected to the base 2 at the bottom, and the drive assembly 42 is carried by the mounting plate 45. A servo motor 441 is provided on one side of the linear guide rail 440 along the first direction to drive the mounting plate 45 to move in the third direction.

[0039] For example, the distance between the grinding wheel 41 and the clamping opening 200 in the third direction is adjusted by a linear guide 440. The smaller the distance, the deeper the cutting depth of the lithium battery 8. The servo motor 441 provides high-precision positioning capabilities, ensuring that the cutting mechanism 4 can accurately move to the predetermined position for cutting operations. The linear guide 440 provides a stable motion path, ensuring the stability of the cutting mechanism 4 during movement, helping to reduce friction and wear on the moving assembly 44 during movement, and extending the service life of the device.

[0040] In some embodiments, reference Figures 1 to 3 The driving assembly 42 further includes a bearing holder 43 . The bearing holder 43 extends along the second direction, has a bottom fixed to the mounting plate 45 , and a top rotatably connected to the rotating shaft 40 for supporting the rotating shaft 40 .

[0041] For example, the bearing retainer 43 can effectively support the rotating shaft 40 , reducing the bending and vibration of the shaft, thereby improving the stability and accuracy of the rotation.

[0042] In some embodiments, reference Figures 1 to 3 The lithium battery shell cutting machine 1 further includes a dust collecting box 5. The dust collecting box 5 is arranged between the clamping device 3 and the cutting mechanism 4 along the first direction, and is correspondingly arranged below the clamping port 200 and the grinding wheel 41 for collecting cutting dust.

[0043] In some embodiments, reference Figures 1 to 3 The lithium battery shell cutting machine 1 further includes a cover 6. The cover 6 is provided on the clamping device 3 and the cutting mechanism 4 and is connected to the base 2. The cover 6 includes a protective cover 60, which is detachably connected to the cover 6 and is correspondingly provided with the dust collection box 5.

[0044] For example, the hood 6 prevents dust and debris generated during the cutting process from scattering, maintaining a clean working environment. It also protects the interior of the device from dust and dirt that may affect its performance. The protective cover 60, positioned corresponding to the dust box 5, effectively collects dust and debris generated during the cutting process, improving dust collection efficiency and reducing pollution to the working environment. The detachable connection between the protective cover 60 and the hood 6 can be a screw connection or a wedge pin connection.

[0045] In some embodiments, reference Figures 1 to 3 A first speed regulator 61, a second speed regulator 62, and a control panel 63 are provided on one side of the hood 6 along the third direction. The first speed regulator 61 is electrically connected to the first stepper motor 210 for regulating the first stepper motor 210. The second speed regulator 62 is electrically connected to the second stepper motor 420 for regulating the second stepper motor 420. The control panel 63 is connected to the first speed regulator 61, the second speed regulator 62, and the servo motor 441.

[0046] For example, the control screen 63 is used to adjust and display the motor parameters. The cutting depth is controlled by the servo motor 441, and the value can be set on the touch screen. The servo motor 441 can return to its original position after completing the set distance.

[0047] In some embodiments, reference Figures 1 to 3 The lithium battery shell cutting machine 1 further includes an electrical cabinet 7. The electrical cabinet 7 is provided on one side of the linear guide rail 440 along the third direction and is connected to the first speed regulator 61, the second speed regulator 62, the servo motor 441 and the control panel 63.

[0048] For example, the electrical control cabinet is equipped with PLC, solenoid valves and other electrical components to realize the automated operation of the device. For example, the servo motor 441 is controlled by the PLC to achieve precise movement and automatically return to its original position after completing the set trajectory, protecting the lithium battery 8.

[0049] In some embodiments, the inflatable clamping mechanism 20 is compatible with cylindrical lithium batteries 8 having a diameter of 30-50 mm.

[0050] For example, the inflatable clamping mechanism 20 can be replaced with other models to match batteries with different diameters.

[0051] The working principle of the lithium battery shell cutting machine 1 provided in this application is as follows:

[0052] Place the lithium battery 8 into the clamping port 200 of the inflatable clamping mechanism 20, click the clamping button on the control screen 63, and the lithium battery 8 is now fixed. Then set the cutting depth on the parameters of the control screen 63 according to the shell thickness, as well as the parameters of the first speed regulator 61 and the second speed regulator 62, and start the start button. The first stepper motor 210 and the second stepper motor 420 rotate at the same time, and the linear guide 440 drives the cutting mechanism 4 to quickly reach the preset position (near the lithium battery 8), and then slowly move toward the lithium battery 8. The grinding wheel 41 cuts the shell of the lithium battery 8 at high speed, and the cut dust falls into the dust collection box 5. It stops automatically after completing the cutting route under the control of the PLC in the electrical cabinet 7.

[0053] Click the clamping cylinder button again to release the lithium battery 8. Use pliers to easily peel off the cut shell that is about to fall off. After the internal battery cell is exposed, it can be manually pulled out for subsequent disassembly.

Its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the scope of protection of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the scope of protection of the utility model.
