Description

Technical Field

[0001] This utility model relates to the field of waste battery recycling, and more specifically, it relates to a waste battery positive and negative electrode separator. Background Technology

[0002] Battery recycling refers to the collection of used batteries to prevent them from entering the ecosystem and causing harm to the environment. Batteries contain many valuable metal materials, which need to be separated and recycled.

[0003] A search revealed an existing patent (application number CN202311280069.X) disclosing a battery recycling device. A cutting mechanism is vertically mounted above a cutting station, descending to contact the battery pack and cut its outer casing. A separating mechanism is movably mounted at a separating station, its movement direction perpendicular to the transmission direction of the conveying component. An ejector component ejects the battery cells from the battery pack's casing to a first stripping station. A first stripping mechanism, located at the first stripping station, strips the outer membrane of the battery cells and transfers the inner membrane to a second stripping station. A second stripping mechanism, located at the second stripping station, disassembles the inner membrane of the battery cells and recovers the electrode sheets attached to it. This invention eliminates the need for manual intervention, increasing automation and efficiency. However, the inventors discovered the following problems with the existing technology during the development of this invention:

[0004] Most existing waste battery recycling devices reprocess the batteries by crushing them. This method mixes the useful and useless parts of the batteries together, making them difficult to separate. Some recycling devices that use cutting to separate the positive and negative electrode plates require multiple cutting and peeling processes, which takes up a lot of production space.

[0005] Therefore, a waste battery positive and negative electrode separator is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides a waste battery positive and negative electrode separator to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a waste battery positive and negative electrode sheet separator, including a conveying base, on both sides of the conveying base are provided recycling limit boxes, the highest point of the recycling limit box is level with the highest point of the conveying base, and a connecting column is provided on the side of the recycling limit box away from the conveying base, a clamping and rotating device is provided in the connecting column, and a connecting beam connects the two sets of connecting columns.

[0008] A disassembly cylinder is connected to the top of the connecting beam. The bottom end of the telescopic rod of the disassembly cylinder passes through the connecting beam and is connected to a disassembly device. A peeling device is provided at the bottom center of the disassembly device, and cutting connecting blocks are provided on both sides of the peeling device. A cutting blade is connected to the bottom of the cutting connecting block.

[0009] Preferably, the recycling limiting box has a baffle hole and a recycling hole inside, and a baffle cylinder is provided inside the recycling limiting box. The telescopic rod of the baffle cylinder extends into the baffle hole, and a limiting baffle is connected to the top of the telescopic rod of the baffle cylinder.

[0010] Preferably, a rotary motor is connected to one side of the peeling device, a peeling connecting block is connected inside the peeling device, and the output shaft of the rotary motor is slidably connected to the peeling connecting block and the peeling device through a connecting shaft.

[0011] Preferably, a peeling blade is inserted into the bottom of the peeling connecting block, and multiple sets of connecting springs are connected between the peeling blade and the peeling connecting block. The cutting blade is provided with a connecting hole.

[0012] Preferably, the clamping and rotating device includes a rotary motor and a clamping cylinder. The output rod of the clamping cylinder is connected to a fixed clamping block at one end near the conveying base, and the fixed clamping block is located on the same plane as the center line of the recovery hole.

[0013] Preferably, a driving wheel is sleeved on the output shaft of the rotary motor, a driven connecting ring is sleeved on the outer side of the clamping cylinder, and a transmission belt is sleeved between the driving wheel and the driven connecting ring. The driving wheel, the driven connecting ring, and the transmission belt constitute a transmission structure.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] Compared with existing technologies, this waste battery positive and negative electrode separator offers faster peeling operations, simpler mechanics, and the ability to perform multiple peeling and dismantling operations on batteries simultaneously in the same area. It occupies less space, reduces the number of peeling and dismantling steps, and improves battery recycling efficiency. Batteries requiring dismantling and recycling are conveyed to the cutting position by a conveyor base. A baffle cylinder drives a limiting baffle to confine the battery within the cutting and peeling area. Then, a dismantling cylinder on the connecting beam drives the dismantling device, its connected peeling device, and the cutting connecting block to perform the cutting operation. The cutting connecting block then drives the cutting blade. The positive and negative caps at both ends of the battery are cut off. At the same time, the peeling connecting block cuts the protective film on the outside of the battery as the peeling blade descends, thus creating a cut that facilitates peeling. After the battery cell is clamped and fixed, the drive wheel driven by the rotary motor rotates. The drive wheel drives the driven connecting ring and the clamping cylinder connected to it to rotate through the transmission belt. The clamping cylinder then drives the battery it holds to perform the rotational peeling operation. During the peeling operation, the peeling blade with the blade angled downwards performs the rotational peeling operation on the subsequent batteries. Attached Figure Description

[0024] 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. Example

[0025] As attached Figures 1 to 7 The waste battery positive and negative electrode sheet separator shown includes a conveying base 1. Both sides of the conveying base 1 are provided with recycling limit boxes 2. The highest point of the recycling limit box 2 is level with the highest point of the conveying base 1. A connecting column 3 is provided on the side of the recycling limit box 2 away from the conveying base 1. A clamping and rotating device 4 is provided inside the connecting column 3. A connecting beam 5 is connected between the two sets of connecting columns 3.

[0026] A disassembly cylinder 51 is connected to the top of the connecting beam 5. The bottom end of the telescopic rod of the disassembly cylinder 51 passes through the connecting beam 5 and is connected to the disassembly device 6. A peeling device 62 is provided at the bottom center of the disassembly device 6, and a cutting connecting block 61 is provided on both sides of the peeling device 62. A cutting blade 611 is connected to the bottom of the cutting connecting block 61.

[0027] Specifically: The batteries that need to be disassembled and recycled are conveyed by the conveying base 1 to a position perpendicular to the recycling limit box 2, and the disassembly device 6 can be moved up and down by the disassembly cylinder 51 on the connecting beam 5. During the downward movement of the disassembly device 6, the peeling device 62 and the cutting connecting block 61 are driven to perform the cutting work. The cutting connecting block 61 drives the cutting blade 611 to cut off the positive and negative caps at both ends of the battery. After the cutting is completed, the clamping and rotating device 4 on the connecting column 3 clamps and fixes the battery, and can drive the battery to rotate and peel off during the peeling work.

[0028] In a preferred embodiment, the recycling limiting box 2 is provided with a baffle hole 22 and a recycling hole 23. A baffle cylinder 21 is provided inside the recycling limiting box 2. The telescopic rod of the baffle cylinder 21 extends into the baffle hole 22, and the top of the telescopic rod of the baffle cylinder 21 is connected to a limiting baffle 211. Furthermore, the limiting baffle 211 is driven by the baffle cylinder 21 to extend out of the baffle hole 22, and the battery can be limited in the cutting and stripping area by the limiting baffle 211. The positive and negative terminal caps of the battery cut off by the cutting blade 611 fall into the recycling limiting box 2 through the recycling hole 23 for recycling and collection.

[0029] In a preferred embodiment, a rotary motor 621 is connected to one side of the peeling device 62, and a peeling connecting block 622 is connected inside the peeling device 62. The output shaft of the rotary motor 621 is slidably connected to the peeling connecting block 622 and the peeling device 62 via a connecting shaft. Furthermore, the rotary motor 621 and the peeling device 62 drive the peeling connecting block 622 and the rotary motor 621 to control the lifting and moving of the model, and the rotary motor 621 drives the peeling connecting block 622 to rotate inside the peeling device 62.

[0030] In a preferred embodiment, a peeling blade 623 is inserted into the bottom of the peeling connecting block 622, and multiple sets of connecting springs 624 are connected between the peeling blade 623 and the peeling connecting block 622. A connecting hole 612 is provided on the cutting blade 611. Furthermore, the peeling connecting block 622 cuts the protective film on the outside of the battery while driving the peeling blade 623 to descend, thereby cutting a cut on the protective film on the outside of the battery that is easy to peel off. When the peeling connecting block 622 rotates, it drives the peeling blade 623 to rotate, so that the blade is angled downward to perform the subsequent rotational peeling work of the battery. When peeling off the positive and negative electrode plates of the battery and the separator between the positive and negative electrode plates, the peeling blade 623 can be lowered by the connecting springs 624, so that the blade is always in contact with the position to be peeled off.

[0031] In a preferred embodiment, the clamping and rotating device 4 includes a rotary motor 41 and a clamping cylinder 42. The output rod of the clamping cylinder 42 is connected to a fixed clamping block 421 near the end of the conveying base 1, and the fixed clamping block 421 and the center line of the recycling hole 23 are located on the same plane. Furthermore, after the positive and negative electrode caps at both ends of the battery are cut off, the clamping cylinder 42 drives the fixed clamping block 421 to move through the connecting hole 612 toward the battery, and the battery core is clamped and fixed by the two sets of fixed clamping blocks 421.

[0032] In a preferred embodiment, a drive wheel 411 is sleeved on the output shaft of the rotary motor 41, and a driven connecting ring 422 is sleeved on the outer side of the clamping cylinder 42. A transmission belt 43 is sleeved between the drive wheel 411 and the driven connecting ring 422. The drive wheel 411, the driven connecting ring 422, and the transmission belt 43 constitute a transmission structure. Furthermore, after the battery cell is clamped and fixed, the drive wheel 411 driven by the rotary motor 41 rotates, and the drive wheel 411 drives the driven connecting ring 422 and the clamping cylinder 42 connected to it to rotate through the transmission belt 43. Then, the clamping cylinder 42 drives the battery it clamps to perform a rotational peeling operation.

[0033] The working process of this utility model is as follows: First, the battery that needs to be disassembled and recycled is conveyed by the conveying base 1 to a position perpendicular to the recycling limit box 2. When the battery reaches the cutting position, the baffle cylinder 21 drives the limit baffle 211 to extend out of the baffle hole 22. The limit baffle 211 can limit the battery in the cutting and peeling area. Then, the disassembly cylinder 51 on the connecting beam 5 drives the disassembly device 6 to move up and down. During the downward movement of the disassembly device 6, the peeling device 62 and the cutting connecting block 61 are driven to perform the cutting work. The cutting connecting block 61 drives the cutting blade 611 to cut off the positive and negative terminal caps at both ends of the battery. The positive and negative terminal caps at both ends of the battery cut off by the cutting blade 611 fall into the recycling limit box 2 through the recycling hole 23 for recycling and collection.

[0034] Meanwhile, as the peeling connecting block 622 moves the peeling blade 623 downward, it cuts the protective film on the outside of the battery, thus creating a cut that is easy to peel off. After the positive and negative caps at both ends of the battery are cut off, the clamping cylinder 42 drives the fixing clamp 421 to move through the connecting hole 612 toward the battery. The two sets of fixing clamps 421 clamp and fix the battery core. At the same time, the rotary motor 621 drives the peeling connecting block 622 to rotate inside the peeling device 62. When the peeling connecting block 622 rotates, it drives the peeling blade 623 to rotate, so that the blade is angled downward.

[0035] After the battery cell is clamped and fixed, the active rotating wheel 411 driven by the rotary motor 41 rotates. The active rotating wheel 411 drives the driven connecting ring 422 and the clamping cylinder 42 connected to it to rotate through the transmission belt 43. Then, the clamping cylinder 42 drives the battery it clamps to rotate and peel off. During the peeling operation, the peeling blade 623 with the blade angled downwards performs the rotational peeling operation on the subsequent battery. When peeling off the positive and negative electrode plates of the battery and the separator between the positive and negative electrode plates, the peeling blade 623 can be lowered by the connecting spring 624 so that the blade always keeps in contact with the position to be peeled off. The above is the working principle of this waste battery positive and negative electrode plate separator.
