Description

Technical Field

[0001] This invention relates to the technical field of battery disassembly, and in particular to a clamping and separating device and control method suitable for battery modules. Background Technology

[0002] Dismantling of waste battery modules is a core link in the lithium battery recycling industry chain. Its dismantling efficiency and safety directly determine the production cost and operational risks of recycling companies. In the existing technology, battery module dismantling mostly adopts a manual-assisted semi-automatic method, which requires manual cutting of the connecting wires between modules, and then using clamps to hold the modules and flip them over to pour out the internal cells.

[0003] However, the existing disassembly equipment has the following drawbacks: the clamp can only clamp from the side, and the cells inside different modules are easily damaged by excessive force during the flipping process, or the internal batteries are easily detached from the module frame and damaged during the flipping process. Secondly, the battery wires need to be cut manually, and the existing cutting machines cannot automatically adapt to wires with different horizontal and vertical directions.

[0009] In a preferred embodiment of the present invention, the cutting assembly includes a first bracket fixed on a base, a first guide rail provided on the first bracket, a first slider slidably connected to the first guide rail, a first telescopic device fixed to the front side of the first slider, a first connecting rod fixedly connected to the telescopic end of the first telescopic device, a first lifting device fixed to the end of the first connecting rod, a first lifting plate slidably connected to the front side of the first lifting device, a first fixing frame fixed to the front side of the first lifting plate, a cutting machine mounted on the first fixing frame, and the cutting blade rotatably connected to the bottom of the cutting machine.

[0010] In a preferred embodiment of the present invention, the first transport component includes a first motor and a second support frame fixed on a base. A first pulley is rotatably connected to the second support frame, and a second pulley is rotatably connected to the base. A belt is sleeved between the first pulley and the second pulley, and a conveyor plate is fixed on the belt. A second guide rail is provided above the second support frame, and the conveyor plate is slidably connected to the second guide rail. The output end of the first motor is fixedly connected to the rotation shaft of the first pulley.

[0011] As a preferred embodiment of the present invention, the second transport component has the same structure as the first transport component, and the second transport component is provided with a second battery pack.

[0012] As a preferred embodiment of the present invention, the separation component includes a third support frame fixed on the base, and a second set of switching components is provided on the third support frame. The second set of switching components has the same structure as the first bracket, first guide rail, first slider, first connecting rod, first lifter, and first lifting plate in the cutting component. A second telescopic device is fixed to the lower side of the lifting plate of the second set of switching components. A shock absorber is fixed to the telescopic end of the second telescopic device, and multiple suction cups are fixed to the bottom of the shock absorber.

[0013] This invention also provides a control method for a battery module clamping and separating device, employing the clamping and separating device for battery modules as described above, comprising the following steps: S1. Place the first battery pack upside down on the conveyor plate of the first transport component, start the first motor, and drive the conveyor plate to move along the second guide rail through belt drive to transport the first battery pack to the cutting station. S2. The cutting assembly adjusts the left and right position of the cutting machine through the first slider, adjusts the front and rear position through the first telescopic device, and adjusts the height position through the first lifting device. It drives the cutting machine to drive the cutting blade to cut, and changes the cutting direction to longitudinal or transverse by rotating, and sequentially cuts all transverse and longitudinal connected wires on the bottom surface of the first battery pack. S3. The cylinder drives the balance plate to rise along the guide rod, bringing the clamping assembly to the same height position as the side of the battery pack. The clamping assembly uses the bidirectional cylinder to drive the clamping plate to close and clamp the first battery pack.

Then it rises to separate the battery from the base plate and transfers the battery into the collection chamber, completing the separation.

[0014] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: This invention, through clamping and linkage lifting, automatically drives the support plate to insert and lift from the bottom of the battery pack during the clamping process. Simultaneously, springs buffer the clamping force, preventing damage to the battery casing from excessive clamping force and completely solving the problem of internal cells easily falling off during the flipping process of existing clamps, thus improving the safety of the disassembly process. By setting up multi-dimensional adjustable cutting components, coupled with a 90° rotating cutting blade, the left-right, front-back, and height positions of the cutting machine can be flexibly adjusted, and the horizontal and vertical cutting directions can be switched with one click, eliminating the need for manual adjustment of the cutting angle and position. It automatically adapts to battery module connecting wires with different orientations, significantly improving the efficiency and accuracy of wire cutting. The first and second transport components work independently and synchronously, allowing the cutting station and separation station to operate simultaneously. While the first battery pack undergoes wire cutting and flipping, the second battery pack can simultaneously undergo cell separation, solving the problem of low equipment utilization caused by the serial operation of existing equipment, and significantly improving overall disassembly efficiency.

To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0018] Please see Figure 1-7 The present invention provides a technical solution: a clamping and separating device and control method for battery modules, comprising a base 1, on which a first transport component, a cutting component, a clamping and flipping component, a second transport component 411, a separating component and a first battery pack 6 are sequentially arranged. The cutting component has a cutting blade 209 that can rotate 90° at the bottom. The bottom of the first battery pack 6 is fixedly installed with a base plate 602. The clamping and flipping component includes a clamping component 3 that can rotate 180°. The clamping component 3 is provided with a lifting mechanism, which includes a support plate 320. When clamping the battery pack, the support plate 320 automatically extends from the bottom to lift it. A collection compartment 8 is fixed on the base 1.

[0019] Specifically, the conventional first battery pack 6 contains batteries, which are supported by the bottom plate 602 and connected by wires. During the splitting operation, the worker needs to place the first battery pack 6 with its bottom facing up on the first transport component. Then, the first battery pack 6 is transported to the cutting component for wire cutting. After that, the clamping and flipping component clamps the cut first battery pack 6 and flips it 180°. At the same time, it is transported to the separation component by the second transport component 411. The separation component separates the batteries from the bottom plate 602 and transfers them to the collection bin 8, realizing the parallel operation of the cutting station and the separation station.

[0020] Based on the above embodiments, the cutting component can be adjusted to the left and right, front and back, and height positions. The cutting blade 209 at the bottom can rotate 90° to switch the cutting direction, cutting the horizontal and vertical wires on the battery pack in sequence. During the clamping and flipping process, the support plate 320 automatically inserts from the bottom to lift the first battery pack 6, preventing the internal batteries from falling out during flipping. The second transport component 411 adopts the same transport structure as the first transport component, which can simultaneously transport different batches of battery packs. The separation component uses multiple suction cups 713 to adsorb the top surface of the battery. After rising, the battery can be separated from the bottom plate 602 and then transferred to the collection chamber 8 for collection.

[0021] The clamping and flipping assembly includes a guide rod 503 and a cylinder 504 fixed on the base 1. The telescopic end of the guide rod 503 and the rod end of the cylinder 504 are jointly fixed to a balance plate 502. A flipping machine 5 is installed on the balance plate 502. A connecting rod 501 is fixed to the output end of the flipping machine 5. The clamping assembly 3 is fixed to the end of the connecting rod 501.

[0022] Specifically, cylinder 504 drives balance plate 502 to move up and down along guide rod 503, causing clamping assembly 3 to be adjusted to a height position matching the battery pack. The flipping machine 5 drives clamping assembly 3 to rotate as a whole through connecting rod 501, realizing the 180° flipping action of the battery pack.

[0023] Based on the above embodiments, the guide rods 503 are symmetrically distributed on both sides of the cylinder 504 to ensure the levelness of the balance plate 502 during the lifting and lowering process. The flipping machine 5 has a self-locking function and can stop at any angle to prevent the battery pack from slipping during the flipping process.

[0024] A bidirectional cylinder 301 is fixedly mounted on the clamping assembly 3. Two clamping plates 302 are symmetrically arranged at the two ends of the cylinder 301's double-sided rods. A lifting mechanism is mounted on each clamping plate 302. The lifting mechanism also includes a threaded ring 310, which is fixedly mounted on the clamping plate 302. A threaded rod 311 is threaded into the threaded ring 310. A buffer plate 312 is rotatably connected to the inner side of the threaded rod 311. A spring 313 is sleeved on the threaded rod 311. Both ends of the spring 313 are connected to the buffer plate 312 and the clamping plate 302, respectively. A coaxially fixed... The telescopic tube 314 has a second fixed frame 315 fixed on the clamping plate 302. The telescopic end of the telescopic tube 314 is rotatably connected to the second fixed frame 315. The telescopic end of the telescopic tube 314 is fixed with a first helical gear 316. The second fixed frame 315 is rotatably connected with a second helical gear 317. The first helical gear 316 and the second helical gear 317 mesh with each other. The lower end of the second helical gear 317 is coaxially fixed with a gear 318. A rack 319 is slidably connected inside the second fixed frame 315. The gear 318 meshes with the rack 319. The support plate 320 is fixed to the end of the rack 319.

[0025] Specifically, during clamping, the bidirectional cylinder 301 is activated, and by retracting the air rods at both ends, it drives the two clamping plates 302 connected to the ends of the air rods to simultaneously close towards the middle and clamp the battery pack. The buffer plate 312 first contacts the side of the battery pack and moves backward. The compression spring 313 simultaneously drives the threaded rod 311 to move. When the threaded rod 311 passes through the threaded ring 310, it is affected by the thread engagement and rotates at the same time, thereby driving the telescopic tube 314 to rotate synchronously. When the telescopic tube 314 rotates, it retracts, driving the first helical gear 316 to rotate without affecting its position. Through the transmission of the second helical gear 317, the rotation of the first helical gear 316 will synchronously drive the rotation of the gear 318, thereby driving the rack 319 to drive the support plate 320 to move inward horizontally. When the spring 313 is compressed and the clamping force reaches the set value, the support plate 320 is fully inserted into place. Then the flipping machine 5 starts to drive the battery pack to flip. During the flipping process, the support plate 320 supports the internal battery in the first 90° flipping section, and the bottom plate 602 supports the internal battery in the second 90° flipping section, effectively preventing the battery from falling off during the flipping process.

[0026] Based on the above embodiments, when the clamping plate 302 closes to clamp the first battery pack 6, in order to prevent the clamping force of the first battery pack 6 of different sizes from being different, resulting in excessive clamping force and damage to the battery, the buffer plate 312 can effectively buffer the pressure using the compression spring 313, and extend the support plate 320 at the same time as clamping to achieve linkage.

[0027] The cutting assembly includes a first bracket 2 fixed on a base 1, a first guide rail 201 on the first bracket 2, a first slider 202 slidably connected to the first guide rail 201, a first telescopic device 203 fixed to the front side of the first slider 202, a first connecting rod 204 fixedly connected to the telescopic end of the first telescopic device 203, a first lifting device 205 fixed to the end of the first connecting rod 204, a first lifting plate 206 slidably connected to the front side of the first lifting device 205, a first fixing frame 207 fixed to the front side of the first lifting plate 206, a cutting machine 208 mounted on the first fixing frame 207, and a cutting blade 209 rotatably connected to the bottom of the cutting machine 208.

[0028] Specifically, the first slider 202 slides left and right along the first guide rail 201 to adjust the left and right position of the cutting machine 208. The first telescopic device 203 extends or retracts the telescopic rod, and the first lifting device 205 moves forward or backward with the first connecting rod 204. The first lifting device 205 drives the first lifting plate 206 to slide up and down to adjust the height position of the cutting machine 208. The cutting machine 208 can drive the cutting blade 209 to move up and down at a high frequency to achieve cutting. At the same time, the cutting machine 208 can drive the cutting blade 209 to rotate 90° to achieve cutting of horizontal and vertical wires.

[0029] Based on the above embodiments, the first connecting rod 204 effectively reduces the overall mechanical volume, making the cutting assembly compact and saving manufacturing costs. Multiple adjusters can precisely control the cutting action of the cutting blade 209, enabling it to perfectly adapt to the cutting of battery module connecting wires in different positions and different connection directions, thereby improving cutting efficiency and reducing the working time required for separation.

[0030] The first transport component includes a first motor 4 and a second support frame 401 fixed on a base 1. A first pulley 402 is rotatably connected to the second support frame 401, and a second pulley 404 is rotatably connected to the base 1. A belt 403 is sleeved between the first pulley 402 and the second pulley 404. A conveyor plate 405 is fixed on the belt 403. A second guide rail 406 is provided above the second support frame 401. The conveyor plate 405 is slidably connected to the second guide rail 406. The output end of the first motor 4 is fixedly connected to the rotation shaft of the first pulley 402.

[0031] Specifically, the first motor 4 drives the first pulley 402 to rotate, and the second pulley 404 rotates synchronously through the belt 403. The belt 403 drives the conveyor plate 405 to move horizontally along the second guide rail 406, transporting the battery pack to the designated work station.

[0032] Based on the above embodiments, the displacement of the conveyor plate 405 is controlled by the first motor 4, thereby realizing the switching of the work position of the first battery pack 6.

[0033] The second transport component 411 has the same structure as the first transport component, and the second transport component 411 is provided with a second battery pack 601.

[0034] Specifically, the second transport component 411 is the same as the first transport component and operates synchronously and independently, respectively transporting different batches of battery packs. The second transport component 411 can fix and grip the base plate 602 of the second battery pack 601. The only difference between the second battery pack 601 and the first battery pack 6 is that the second battery pack 601 is the battery pack after the wires have been cut.

[0035] Based on the above embodiments, the second transport component 411 is responsible for transporting the second battery pack 601 after the wire cutting is completed, so as to ensure that the first transport component can continue to transport new batteries that need to be cut.

[0036] The separation assembly includes a third support frame 7 fixed on the base 1. A second set of switching components 701 is provided on the third support frame 7. The second set of switching components 701 has the same structure as the first bracket 2, first guide rail 201, first slider 202, first connecting rod 204, first lifter 205, and first lifting plate 206 in the cutting assembly. A second telescopic device 710 is fixed to the lower side of the lifting plate of the second set of switching components 701. A shock absorber 711 is fixed to the telescopic end of the second telescopic device 710. Multiple suction cups 713 are fixed to the bottom of the shock absorber 711.

[0037] Specifically, the second set of switching components 701 drives the suction cup 713 to adjust to the corresponding position above the battery pack. The second telescopic device 710 drives the suction cup 713 to descend and contact the top surface of the battery pack. The suction cup 713 generates a vacuum suction force to fix the battery. The second telescopic device 710 drives the suction cup 713 to rise, separating the battery from the base plate 602 and transporting the separated battery to the collection chamber 8.

[0038] Based on the above embodiments, the shock absorber 711 can buffer the impact force when the suction cup 713 descends, avoiding damage to the battery pack casing. The multiple suction cups 713 are arranged in a rectangular shape to evenly adsorb the top surface of the battery pack, ensuring a firm adsorption.

[0039] This embodiment also provides a control method for a battery module clamping and separating device, which uses the above-mentioned clamping and separating device for battery modules and includes the following steps: S1. Place the first battery pack 6 upside down on the conveyor plate 405 of the first transport component, start the first motor 4, and drive the conveyor plate 405 to move along the second guide rail 406 through the belt 403 to transport the first battery pack 6 to the cutting station. S2. The cutting assembly adjusts the left and right position of the cutting machine 208 through the first slider 202, adjusts the front and back position through the first telescopic device 203, and adjusts the height position through the first lifting device 205. It drives the cutting machine 208 to drive the cutting blade 209 to cut, and changes the cutting direction to longitudinal or transverse by rotating, and sequentially cuts all transverse and longitudinal connected wires on the bottom surface of the first battery pack 6. S3, cylinder 504 drives balance plate 502 to rise along guide rod 503, driving clamping component 3 to the same height position on the side of battery pack. Clamping component 3 uses bidirectional cylinder 301 to drive clamping plate 302 to close and clamp the first battery pack 6. During the clamping process, support plate 320 automatically inserts from the bottom and lifts it. Then, flipping machine 5 drives the first battery pack 6 to complete 180° flipping, so that bottom plate 602 is placed face down on the second transport component 411. S4, the second transport component 411 is activated, transporting the second battery pack 601 to the separation station; S5. The second set of switching components 701 moves the suction cup 713 to above the second set of battery packs 601. The second telescopic device 710 drives the suction cup 713 to descend and adsorb the battery. Then it rises to separate the battery from the base plate 602 and transfers the battery into the collection chamber 8 to complete the separation.

[0040] This control method adopts a dual-station parallel operation mode. The first transport component and the second transport component 411 work independently and synchronously. The cutting station and the separation station operate simultaneously. After the first battery pack 6 completes the wire cutting, the clamping component 3 works with the lifting mechanism to complete the clamping and flipping action to prevent the internal batteries from falling out. The second battery pack 601 is synchronously transported to the separation station, where the suction cup 713 completes the separation and transfer of the battery from the base plate 602. The entire process does not require manual intervention and automatically completes the wire cutting, clamping and flipping and cell separation processes of the battery module.
