[0002] In the field of cylindrical lithium battery recycling, traditional methods for separating cells and casings have many insurmountable drawbacks. Regarding mechanical dismantling, taking common methods like cutting and squeezing as examples, the complex structure of cylindrical lithium batteries and the tight connection between the cell and casing require operators with extremely high precision and experience. Even slight deviations can cause the blade to cut into the cell, damaging its internal structure and electrode materials, thus reducing the quality and recovery rate of recyclable materials. Furthermore, the vibrations and impacts generated during mechanical dismantling can easily deform the cell, further affecting recycling efficiency. In addition, blades wear down easily after prolonged use, requiring frequent replacements, which increases equipment maintenance costs.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: although cylindrical lithium batteries can be cut, damage is easily caused during mechanical disassembly, resulting in cell damage and thus reducing efficiency and safety. Therefore, we propose a cell and casing separation device for cylindrical lithium batteries to solve the above-mentioned problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a device for separating the cell and casing of a cylindrical lithium battery, including a workbench 1, a conveyor belt 2 disposed on the top surface of the workbench 1, and further including: a clamping assembly 4, of which multiple clamping assemblies 4 are arranged in a linear array, the clamping assemblies 4 are disposed on the top surface of the conveyor belt 2, and the clamping assemblies 4 are used to clamp the cylindrical lithium battery; a cutting assembly 5, disposed on one side of the conveyor belt 2, the cutting assembly 5 is used to cut the cylindrical lithium battery clamped by the clamping assembly 4; a protective assembly 3, disposed on the outside of the clamping assembly 4, the protective assembly 3 is used to block direct and reflected laser light; and a touch screen all-in-one machine 6, the touch screen all-in-one machine 6 is disposed on one side surface of the protective assembly 3;

[0028] When it is necessary to cut cylindrical lithium batteries, the worktable 1 is first installed in a preset position, and then the conveyor belt 2 is fixedly connected to the top surface of the worktable 1. Since multiple clamping components 4 are fixedly connected to the top surface of the conveyor belt 2, and protective components 3 are fixedly connected to the outside of the clamping components 4, and a cutting component 5 is fixedly connected to one side of the inner cavity of the protective component 3, the worktable 1 can provide support for the conveyor belt 2 and the protective component 3, and the conveyor belt 2 can provide support for the multiple clamping components 4, so that the protective component 3 can provide support for the cutting component 5. At the same time, the multiple clamping components 4 can clamp and limit the multiple cylindrical lithium batteries. Then, the conveyor belt 2 and the cutting component 5 are controlled by the touch screen all-in-one machine 6, so that the conveyor belt 2 can transport the cylindrical lithium batteries clamped by the multiple clamping components 4, and the cutting component 5 can cut the cylindrical lithium batteries in sequence, so as to improve work efficiency. Then, the protective component 3 can block direct laser light and reflection, thereby improving safety.

[0029] See Figure 1 , Figure 2 , Figure 3The protective component 3 includes a protective cover 31, which is disposed on the top surface of the workbench 1. Both sides of the protective cover 31 have inlet and outlet holes 32 at the lower position. A limit groove 33 is formed on one side of the inner cavity of the protective cover 31. An installation groove 34 is formed at the center of the bottom surface of the inner cavity of the limit groove 33. The inner cavity of the installation groove 34 is connected to the cutting component 5. An installation hole 35 is formed at the upper position of one side of the protective cover 31. An observation window 36 is provided in the inner cavity of the installation hole 35.

[0030] The protective cover 31 in the protective assembly 3 can be fixedly connected to the top surface of the workbench 1 and also provide a mounting base for the inlet / outlet hole 32. This allows the conveyor belt 2 to carry the cylindrical lithium batteries held by multiple clamping components 4 through the inlet / outlet hole 32 into the inner cavity of the protective cover 31. Because a limiting groove 33 is formed on one side surface of the inner cavity of the protective cover 31, and a mounting groove 34 is formed at the center of the bottom surface of the limiting groove 33, and the inner cavity of the mounting groove 34 is connected to the cutting assembly 5, the workbench 1 can provide support for the protective cover 31, thereby allowing the mounting groove 34 to... The cutting component 5 is fixed in a limiting position so that the limiting groove 33 can guide the cutting component 5. Since the protective cover 31 has a mounting hole 35 on one side surface near the upper position, and the inner cavity of the mounting hole 35 is fixedly connected to the observation window 36, the protective cover 31 can provide support for the observation window 36, so that the staff can observe the inside through the observation window 36, so as to detect abnormalities in the cylindrical lithium battery during the cutting process in time, ensuring that the entire cell and shell separation process is stable and efficient, and improving separation quality and production efficiency.

[0031] See Figure 1 , Figure 2 , Figure 4 , Figure 5 The clamping assembly 4 includes a limiting plate 41, which is disposed on the top surface of the conveyor belt 2. Both sides of the top surface of the limiting plate 41 are provided with shrink boxes 42. Both sides of the inner surface of the two shrink boxes 42 are provided with limiting posts 43 at the center position of one side. The inner cavity of the two limiting posts 43 is provided with springs 44. One end of the two springs 44 is provided with a telescopic post 45. One end of the telescopic post 45 is provided with an arc-shaped clamping plate 46. Both sides of the inner surface of the shrink box 42 are provided with guide grooves 47. Both sides of the telescopic post 45 are provided with guide plates 48. The guide plates 48 are connected to the guide grooves 47. The connection between the telescopic post 45 and the arc-shaped clamping plate 46 is provided with slots 49. There are two slots 49, which are symmetrically distributed. Both slots 49 are provided with insert blocks 410. The top-view outer diameter of the telescopic post 45 is the same as the top-view inner diameter of the shrink box 42, and the two are compatible.

[0032] The limiting plate 41 in the clamping assembly 4 can be fixedly connected to the top surface of the conveyor belt 2 and also provide an installation base for the shrink box 42. Since limiting posts 43 are fixedly connected to both sides of the center position of one side surface of the inner cavity of the two shrink boxes 42, and springs 44 are fixedly connected to the inner cavity of each limiting post 43, and telescopic posts 45 are movably connected to one end of each spring 44, and arc-shaped clamping plates 46 are connected to one end of each telescopic post 45, the telescopic posts 45 can extend and retract within the inner cavity of the shrink box 42 via the springs 44, thereby enabling the limiting posts 42 to extend and retract. Position post 43 limits the spring 44, thereby enabling the arc-shaped clamping plate 46 to flexibly clamp the cylindrical lithium battery under the elastic force of the spring 44. This ensures clamping stability and avoids damage to the lithium battery. It also accommodates cylindrical lithium batteries of different diameters, improving the applicability and flexibility of the device. Furthermore, it ensures that the cylindrical lithium battery maintains a stable position during the separation of the cell and casing. Since guide grooves 47 are provided on both sides of the inner cavity of the shrink box 42, and both sides of the telescopic post 45 are fixed... A guide plate 48 is fixedly connected to the telescopic column 45, and the guide plate 48 is connected to the guide groove 47. This allows the telescopic column 45 to move while simultaneously driving the guide plate 48 within the guide groove 47. The guide groove 47 then guides the guide plate 48, enabling the telescopic column 45 to extend and retract within the shrink box 42. This ensures the accuracy and reliability of the arc-shaped clamping plate 46 in holding the cylindrical lithium battery, preventing positional shifts or unstable clamping of the cylindrical lithium battery during cell and casing separation. Because the telescopic column 45 and... The arc-shaped clamp 46 is connected to a slot 49, and there are two slots 49. The two slots 49 are symmetrically distributed, and each slot 49 has a plug 410 inserted into its inner cavity. This allows the plug 410 to be inserted into the inner cavity of the slot 49, thereby enabling the arc-shaped clamp 46 to be disassembled and replaced according to different needs. Since a silicone pad is fixedly connected to the inner cavity of the arc-shaped clamp 46, the friction is increased, thereby preventing the battery from shifting and avoiding rigid contact that could damage the casing.

[0033] See Figure 1 , Figure 2 , Figure 6 The cutting assembly 5 includes an electric telescopic rod 51, which is disposed in the inner cavity of the mounting groove 34. A support plate 52 is disposed at the output end of the electric telescopic rod 51. A pulsed laser 53 is disposed on one side of the top surface of the support plate 52. A cutting head 54 is disposed at the output end of the pulsed laser 53. An infrared sensor 55 is disposed on the top surface of the cutting head 54.

[0034] The electric telescopic rod 51 in the cutting assembly 5 can be fixedly connected to the inner cavity of the mounting slot 34 and also provide a mounting base for the support plate 52. Since a pulsed laser 53 is fixedly connected to one side of the top surface of the support plate 52, and a cutting head 54 is fixedly connected to the output end of the pulsed laser 53, and an infrared sensor 55 is fixedly connected to the top surface of the cutting head 54, the output end of the electric telescopic rod 51 can extend and retract while driving the support plate 52 to move up and down. This allows the limiting slot to guide the support plate 52, enabling the support plate 52 to drive the pulsed laser 53 to move up and down, and simultaneously adjust the position of the cutting head 54, so that the cutting head 54 can be precisely aligned. At the connection point between the cylindrical lithium battery cell and the casing, the pulsed laser 53 emits a high-energy pulsed laser beam through the cutting head 54 to precisely cut the connection point, achieving effective separation of the cell and casing. Then, the infrared sensor 55 can monitor the distance between the cutting head 54 and the lithium battery and the cutting position in real time, and feed the monitored data back to the touch panel 6. The touch panel 6 adjusts the extension and retraction of the electric telescopic rod 51 and the emission parameters of the pulsed laser 53 in a timely manner based on the feedback data, so as to ensure the stability and accuracy of the cutting process, avoid damage to the cell or casing due to cutting deviation, and improve the working efficiency and separation quality of the entire separation device.

[0035] During operation, when cutting cylindrical lithium batteries, the workbench 1 is first installed in a preset position. Then, the conveyor belt 2 is fixedly connected to the top surface of the workbench 1. Since multiple clamping components 4 are fixedly connected to the top surface of the conveyor belt 2, and protective components 3 are fixedly connected to the outside of the clamping components 4, and a cutting component 5 is fixedly connected to one side of the inner cavity of the protective component 3, the workbench 1 can provide support for the conveyor belt 2 and the protective component 3, thereby enabling the conveyor belt 2 to support the multiple clamping components 4, so that the protective component 3 can support the cutting component 5. At the same time, the multiple clamping components 4 can clamp and limit the multiple cylindrical lithium batteries. Then, the conveyor belt 2 and the cutting component 5 are controlled by the touch screen all-in-one machine 6, so that the conveyor belt 2 can transport the cylindrical lithium batteries clamped by the multiple clamping components 4, and the cutting component 5 can cut the cylindrical lithium batteries in sequence, thereby improving work efficiency. The protective component 3 can block direct and reflected laser light, thereby improving safety.

[0036] The protective cover 31 in the protective assembly 3 can be fixedly connected to the top surface of the workbench 1 and also provide a mounting base for the inlet / outlet hole 32. This allows the conveyor belt 2 to carry the cylindrical lithium batteries held by multiple clamping components 4 through the inlet / outlet hole 32 into the inner cavity of the protective cover 31. Because a limiting groove 33 is formed on one side surface of the inner cavity of the protective cover 31, and a mounting groove 34 is formed at the center of the bottom surface of the limiting groove 33, and the inner cavity of the mounting groove 34 is connected to the cutting assembly 5, the workbench 1 can provide support for the protective cover 31, thereby allowing the mounting groove 34 to... The cutting component 5 is fixed in a limiting position so that the limiting groove 33 can guide the cutting component 5. Since the protective cover 31 has a mounting hole 35 on one side surface near the upper position, and the inner cavity of the mounting hole 35 is fixedly connected to the observation window 36, the protective cover 31 can provide support for the observation window 36, so that the staff can observe the inside through the observation window 36, so as to detect abnormalities in the cylindrical lithium battery during the cutting process in time, ensuring that the entire cell and shell separation process is stable and efficient, and improving separation quality and production efficiency.

[0037] The limiting plate 41 in the clamping assembly 4 can be fixedly connected to the top surface of the conveyor belt 2 and also provide an installation base for the shrink box 42.

Position post 43 limits the spring 44, thereby enabling the arc-shaped clamping plate 46 to flexibly clamp the cylindrical lithium battery under the elastic force of the spring 44. This ensures clamping stability and avoids damage to the lithium battery. It also accommodates cylindrical lithium batteries of different diameters, improving the applicability and flexibility of the device. Furthermore, it ensures that the cylindrical lithium battery maintains a stable position during the separation of the cell and casing. Since guide grooves 47 are provided on both sides of the inner cavity of the shrink box 42, and both sides of the telescopic post 45 are fixed... A guide plate 48 is fixedly connected to the telescopic column 45, and the guide plate 48 is connected to the guide groove 47. This allows the telescopic column 45 to move while simultaneously driving the guide plate 48 within the guide groove 47. The guide groove 47 then guides the guide plate 48, enabling the telescopic column 45 to extend and retract within the shrink box 42. This ensures the accuracy and reliability of the arc-shaped clamping plate 46 in holding the cylindrical lithium battery, preventing positional shifts or unstable clamping of the cylindrical lithium battery during cell and casing separation.
