[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0024] Reference Figures 1-4 A device for extracting lithium battery cells includes a processing table 1, on which two guide blocks 9 and a mounting frame 2 are fixedly connected. A cylinder is fixedly mounted on the mounting frame 2, and the drive end of the cylinder is fixedly connected to a laser cutter. The laser cutter is used to cut the lithium battery casing to create conditions for extracting the core. The cross-section of each guide block 9 is an isosceles trapezoid. An electric conveyor belt 8 is provided on the processing table 1 to transport the lithium battery to be processed. Multiple mounting plates 10 are fixedly connected to both sides of the electric conveyor belt 8. A slide rod 14 is slidably connected to each mounting plate 10. A clamping plate 3 is fixedly connected to one end of the slide rod 14. The clamping plate 3 is fixedly connected to the mounting plate 10 by two first springs 6. The two first springs 6 are symmetrically arranged and provide elastic clamping force for the clamping plate 3 and realize reset.

[0025] Each slide bar 14 is equipped with a sliding component, which includes a T-shaped block 5 slidably mounted on the slide bar 14. One end of the T-shaped block 5 is provided with an arc surface. The surface of the guide block 9 and the arc surface of the T-shaped block 5 are relatively smooth, and the friction when they contact is small, which will not affect the movement of the mounting plate 10. To reduce the friction, multiple balls can be rotatably mounted on the arc surface of the T-shaped block 5. When the balls contact the surface of the guide block 9, the friction of the contact surface is small. During the movement of each arc surface, it will gradually move closer to the surface of the corresponding guide block 9. Each T-shaped block 5 is equipped with a moving component, each clamping plate 3 is equipped with a sealing component, and each T-shaped block 5 is fitted with a second spring 15. One end of the second spring 15 is fixedly connected to the T-shaped block 5, and the other end of the second spring 15 is fixedly connected to the slide bar 14. The second spring 15 provides elastic restoring force for the T-shaped block 5. The elastic force of the first spring 6 is smaller than that of the second spring 15.

[0026] Each moving component includes an L-shaped strip 4 fixedly mounted on a T-shaped block 5. One end of the L-shaped strip 4 is provided with a bevel. As the L-shaped strip 4 moves together with the T-shaped block 5, the bevel of the L-shaped strip 4 will gradually come into contact with the upper surface of the lithium battery, effectively preventing the lithium battery from moving up and down. Each clamping plate 3 has a sealing cavity. The sealing component includes a sealing plate 16 that is slidably mounted inside the sealing cavity. A plurality of suction cups 7 that communicate with the sealing cavity are fixedly connected to one side of the clamping plate 3. The suction cups 7 are used to adsorb the surface of the lithium battery.

[0027] Each T-shaped block 5 is fixedly connected to a slide bar 12. The slide bar 12 is fixedly connected to the corresponding sealing plate 16 via a pull rope 11. The mounting plate 10 has two through holes for the pull rope 11 to pass through. The pull rope 11 is U-shaped. The two ends of the inelastic pull rope 11 are fixedly connected to the slide bar 12 and the sealing plate 16, respectively. Each sealing plate 16 is fixedly connected to a third spring 13. The third spring 13 is fixedly connected to the inner wall of the sealing cavity and provides a restoring force for the sealing plate 16.

[0028] In this invention, the lithium battery is placed on the electric conveyor belt 8 and positioned between two corresponding clamping plates 3. During subsequent transport by the electric conveyor belt 8, the arc surfaces of the two T-shaped blocks 5 gradually slide against the inclined surfaces of the two guide blocks 9. The T-shaped blocks 5, the sliding rod 14, and the clamping plates 3 simultaneously slide relative to the mounting plate 10. The first spring 6 and the second spring 15 deform, reducing the distance between the two clamping plates 3, thus allowing for the centered pushing of the lithium battery. At this time, the suction cups 7 on the two clamping plates 3 are tightly attached to the two side surfaces of the lithium battery, and the clamping plates 3 initially provide elastic clamping to the lithium battery from both sides. Simultaneously, the lithium battery exerts a pushing force on the clamping plates 3, preventing the distance between the two clamping plates 3 from further decreasing. As the electric conveyor belt 8 continues to transport the material, the arc surfaces of each T-shaped block 5 continue to move against the inclined surface of the guide block 9. The T-shaped block 5 will slide relative to the slide bar 14, and the second spring 15 will be compressed. When the T-shaped block 5 slides, the sealing plate 16 will be pulled to slide in the sealing cavity through the slide bar 12 and the pull rope 11. The third spring 13 will deform, and the sliding of the sealing plate 16 will create a negative pressure in the sealing cavity. The suction cup 7 will firmly adhere to the surface of the lithium battery. As the L-shaped strip 4 moves with the T-shaped block 5, the inclined surface of the L-shaped strip 4 will gradually adhere to the upper surface of the lithium battery, effectively preventing the lithium battery from moving up and down. This achieves multi-directional clamping from both sides and automatic fixation by surface adsorption. Subsequently, the arc surfaces of the T-shaped blocks 5 can slide along the horizontal surface of the guide block 9.

[0029] After the lithium battery is fixed, the laser cutter precisely cuts its outer shell. After the cutting is completed, the T-shaped block 5 gradually separates from the guide block 9 as it continues to move. The second spring 15 pushes the T-shaped block 5 to reset, the tension of the pull rope 11 disappears, the third spring 13 pulls the sealing plate 16 to reset, the negative pressure of the suction cup 7 disappears, and the adsorption is released. At the same time, the first spring 6 pushes the slide rod 14 and the clamping plate 3 to reset, releasing the lithium battery. Afterwards, the robot can be used to clamp, transfer and recycle the battery cell column, which is convenient for subsequent extraction and recycling of the cell column.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly. For example, they can refer to fixed connection, detachable connection, or integral connection; they can refer to mechanical connection or electrical connection; they can refer to direct connection or indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
