Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery disassembling devices, in particular to a lithium battery quick disassembling device. Background Art

[0002] Lithium batteries generally refer to lithium-ion batteries, which contain lithium salts (and one or more of the elements such as nickel, manganese, and cobalt), have the ability to charge and discharge, and have the advantages of high energy density. However, as the number of charge and discharge times increases, the charging capacity of lithium batteries becomes worse and worse. When the difference reaches a certain level, it will lose its use value and can only be scrapped. Since scrapped lithium batteries contain a large amount of lithium salts, there is a bright prospect for their recycling. To recycle the lithium salts in scrapped lithium batteries, it is necessary to first disassemble the battery with a disassembly device in order to remove the battery core. Utility Model Content

Detailed Embodiments

[0014] To make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concept of the utility model.

[0015] Detailed Embodiments: In combination with Figure 1-2As shown, a lithium battery rapid disassembly device comprises a frame 1, a circular cutting device 2 is arranged on the upper part of the frame 1, a cutting roller 23 and a friction roller 22 with the same rotation direction are arranged inside the circular cutting device 2, and both are driven by a first power device, circular saw blades 231 are arranged at both ends of the cutting roller 23, the distance between the two saw blades 231 is slightly smaller than the length of the battery, the distance from the saw blade 231 to the friction roller 22 is slightly smaller than the diameter of the battery core, the saw blade 231 can cut through one side of the battery shell, the surface of the friction roller 22 is relatively rough and can generate a large friction force, which can drive the battery to rotate, the cutting roller 23 and the friction roller 22 are in a horizontal state, the axes of the cutting roller 23 and the friction roller 22 are parallel to each other, and the distance between the two is A feed hopper 21 is provided above the gap and a guide hopper 24 is provided below the gap. The length of the feed hopper 21 is slightly larger than the length of the battery. The guide hopper 24 is funnel-shaped. A stripping device 3 is provided below the guide hopper 24. The stripping device 3 includes two guide frames 31 respectively provided on both sides below the guide hopper 24. A plurality of conveying wheels 33 driven by a second power device are rotatably connected to the guide frames 31. The conveying wheels 33 can press the two sides of the battery and convey it downward. Cutting devices 32 are provided on both sides of the guide frames 31. The cutting devices 32 can cut through the two sides of the battery shell in the length direction, so that the cross section of the battery shell is semicircular (the central angle is 180 degrees). A material box 4 is provided below the guide frame 31.

[0016] Specifically, the cutting device 32 includes a third motor, and a circular cutting blade is arranged on the rotating shaft of the third motor, and the cutting blade is located in the middle of the line connecting the two guide frames 31. Since there are two cutting devices 32 and they are respectively located on the front and rear sides of the guide frame 31, and the distance between the two cutting blades is slightly smaller than the diameter of the battery core, when the battery is conveyed downward by the conveying wheel 33, the cutting device 32 can cut through both sides of the battery shell in the length direction.

[0017] Furthermore, a groove with an arc-shaped cross section is provided on the outer circumference of the conveying wheel 33 , and the radius of the groove is equal to the radius of the battery.

[0018] Furthermore, a support plate 241 is provided on one side of the top of the guide bucket 24 . When the battery falls from the gap between the cutting roller 23 and the friction roller 22 , one end of the battery will tilt after hitting the support plate 241 , thereby making it easier to enter the guide bucket 24 .

[0019] Specifically, the first power device includes a first motor disposed on one side of the circular cutting device 2, and the first motor is connected to one of the cutting roller 23 and the friction roller 22. One end of the cutting roller 23 and the friction roller 22 are provided with a pulley, and the two pulleys are connected by a belt drive, so that the cutting roller 23 and the friction roller 22 rotate in the same clockwise direction. Figure 2In this case, the cutting roller 23 rotates counterclockwise, making it easy to cut through the battery casing. The friction roller 22 also rotates counterclockwise and can drive the battery to rotate clockwise. When the saw blade 231 cuts through the entire circumference of the battery casing, the diameter at the cut area becomes smaller, and the battery can fall between the two rollers.

[0020] Specifically, the second power device includes a second motor, which is drivingly connected to a conveying wheel 33. One end of the conveying wheel 33 is provided with a pulley. The conveying wheels 33 on the same guiding frame 31 are connected by belt drive (not shown in the figure. At the rear side of the guiding frame, the pulley has two grooves. One groove is connected to the upper pulley by a belt, and the other groove is connected to the lower pulley by a belt). The conveying wheels 33 on the same guiding frame 31 rotate in the same clockwise or counterclockwise direction. One end of each of the two conveying wheels 33 located on two different guiding frames 31 is provided with a gear 34, and the two gears 34 are meshed with each other. The conveying wheels 33 on different guiding frames 31 rotate in opposite clockwise or counterclockwise directions. Figure 2 In this case, the conveying wheel 33 on the left guiding frame 31 rotates clockwise, and the conveying wheel 33 on the right guiding frame 31 rotates counterclockwise, so as to convey the battery downward.

[0021] Working principle: Put the waste cylindrical battery into the feed hopper 21, and make the axis of the battery as parallel as possible to the axis of the cutting roller 23. The battery falls between the friction roller 22 and the cutting roller 23 from the feed hopper 21. After the entire circumference of the outer casing at both ends of the battery is cut through, the battery falls and drops into the guiding hopper 24, and then enters between the conveying wheels 33 on both sides in a vertical posture and is conveyed downward. During this process, the battery casing is cut in half (so that it can be removed from the outside of the battery core), and finally the battery drops into the material box 4 and is collected. Taking out the cut battery from the material box 4, it is easy to remove the battery casing from the outside of the battery core.

[0022] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
