Description

Technical Field

[0001] The present invention relates to the technical field of battery packs, and more specifically, to a disassembly mechanism and a disassembly method for a battery pack. Background Art

[0002] In recent years, battery packs with CTP structure have been increasingly applied and developed. CTP (Cell to Pack, a power battery pack composed of no modules or a few large cells) technology simplifies the original manufacturing process of single cell → module → whole pack to single cell → whole pack, removing the intermediate state of the module. The single cell is fixed on the cold plate by structural adhesive and the cell is pre-tightened by the shell frame to form a battery pack with interference fit. This technology has no traditional end plates and bolts, which saves parts, improves the battery pack volume utilization and production efficiency, and can greatly reduce the weight of the whole pack, thereby increasing energy density and battery life. However, it also greatly reduces the maintainability of the battery. It is extremely difficult to remove the cell from the shell frame during maintenance, and the difficulty of battery recycling has increased dramatically.

[0003] The current disassembly methods of various power battery systems are mostly based on manual operations, which have low efficiency and are difficult to operate, especially when dealing with CTP-type power battery systems. In CTP-type power battery packs, polyurethane glue is usually used to fix the single cells. In the process of removing the cells, the glue removal is the most difficult. Workers generally use physical means such as crowbars or local melt glue to remove the single cells. The disassembly efficiency is low and the time is long. In addition, the disassembly cost and production capacity cannot be applied to large-scale recycling and processing. Disassembly tools such as crowbars are difficult to operate and are prone to safety accidents. In addition, when the existing physical means are used to remove the single cells, colloid will remain on the surface, which will cause certain troubles to the subsequent cell processing. Therefore, it is necessary to propose a disassembly mechanism and disassembly method for battery packs to solve the above problems. Summary of the invention

[0018] As a preferred embodiment of the present invention, a method for disassembling a battery pack comprises the following steps:

[0019] S1: Use laser cutting equipment to horizontally cut the battery pack from the bottom of the side, then remove the upper part of the battery pack, ensure that the bottom plate of the battery pack is flat, and then put the cut battery pack into the softening tank, and then pour a certain volume of water with a temperature of 50 degrees Celsius to 60 degrees Celsius into the softening tank and soak for a period of time;

[0020] S2: After the polyurethane glue for fixing the battery cells is softened, starting from one side of the battery pack, first install the positioning mechanism so that the partition mechanism separates each adjacent battery cell, loosen the floating plate, and use the buoyancy of water to make the floating plate rise, thereby driving the fixing mechanism to descend and cover the top of each battery cell;

[0021] S3: rotating the long rod to allow the fixing clamp to clamp the battery cell, and while clamping the battery cell, the loosening mechanism drives the battery cell to shake, and the second scraper approaches the first scraper;

[0022] S4: After the fixation is completed, the glue removal mechanism contacts the surface of the battery cell, pushes the long rod and then rotates the long rod, the glue removal mechanism descends, and scrapes off the residual colloid on the surface of the battery cell. When the glue removal mechanism reaches the bottom of the battery cell, the cutting blade pops out, scrapes off the adhesive colloid at the bottom of the battery cell, and completely separates the battery cell from the polyurethane glue;

[0023] S5: Remove the positioning mechanism, and take away the separated battery cells together with the device.

[0024] Compared with the prior art, the advantages of the present invention are:

[0025] Taking advantage of the fact that polyurethane glue is easy to soften at a certain temperature, the battery pack is cut open by laser, immersed in warm water to soften, and then the battery cell is disassembled using this device. The user installs the positioning mechanism, then rotates and pushes the long rod to complete the disassembly of the battery cell. While the long rod drives the fixed clamp to clamp the battery cell, it can not only drive the battery cell to swing along the direction of the swing rack through the loosening mechanism, thereby accelerating the separation of the colloid, but also drive the glue removal mechanism to complete the docking, and realize the surrounding glue removal of the battery cell, with good and efficient glue removal effect; the glue removal mechanism can scrape off the colloid on its surface, which not only ensures the efficient separation of the battery cell and the colloid, but also cleans the surface of the battery cell to avoid affecting the subsequent battery cell processing process; when the glue removal mechanism reaches the bottom of the battery cell, it can trigger the cutting mechanism, so that the cutting blade automatically pops out to separate the colloid at the bottom of the battery cell, so that the battery cell is completely separated from the colloid, which is convenient for recycling the battery cell. The whole process is simple and fast, with low operating difficulty, high disassembly efficiency and fast dismantling speed. In addition, multiple sets of synchronously moving fixing mechanisms, glue removal mechanisms and cutting mechanisms are arranged in the positioning strip. Each group synchronously and independently processes each battery cell in the same row, and they are jointly controlled by a long rod to achieve efficient synchronous action and quickly disassemble a whole row of battery cells.

[0026] The expansion plate is first inserted into the polyurethane glue. The blade-like structure and thickness of the end of the expansion plate can not only break the glue, but also increase the distance between two adjacent cells in each row, making it easier for the fixing sleeve to cooperate with each cell. The expansion plate is always close to the surface of the cell during the insertion of the glue. Therefore, the expansion plate can separate the glue in a certain area, so that the cell is initially separated from the glue, which improves the efficiency of subsequent disassembly.

[0027] In order to speed up the loosening efficiency of the battery cell and quickly separate the battery cell from the colloid, the device is provided with a loosening mechanism. When the fixing clamp is driven by the adjusting screw to clamp the battery cell, the sleeve is reciprocated along the direction of the swing rack, thereby driving the battery cell to shake. The pulling of the battery cell and the colloid can speed up the separation of the colloid and the battery cell. BRIEF DESCRIPTION OF THE DRAWINGS

Embodiment 1

[0045] See also Figure 1-14 As shown, the present invention discloses a disassembly mechanism for a battery pack, comprising a softening tank 1, a positioning mechanism 2 is placed inside the softening tank 1, the positioning mechanism 2 comprises a positioning bar 21, a floating plate 23 and an adjusting column 26, the positioning bar 21 is placed in the softening tank 1, the floating plate 23 is slidably connected to the top surface of the positioning bar 21, and the adjusting column 26 is installed inside the positioning bar 21;

[0046] A partition mechanism 3 is installed on the side of the positioning bar 21. The partition mechanism 3 includes a support plate 31. A plurality of support plates 31 are fixed to the side of the positioning bar 21 at equal distances.

[0047] A fixing mechanism 4 is also installed on the side of the positioning bar 21. The fixing mechanism 4 includes a fixing sleeve 41, an adjusting screw 43 and a fixing clamp 45. Several fixing sleeves 41 are fixedly connected in sequence, and several fixing sleeves 41 are slidably connected to the side of the positioning bar 21. The adjusting screw 43 is rotatably connected in the fixing sleeve 41, and the fixing clamp 45 is slidably connected to the bottom of the fixing sleeve 41.

[0048] A loosening mechanism 5 is installed at the bottom of the fixed sleeve 41. The loosening mechanism 5 includes a sleeve disc 55. The sleeve disc 55 is movably connected to the bottom of the fixed sleeve 41.

[0049] A glue removal mechanism 6 is installed at the bottom of the fixed sleeve 41 and the fixed clamp 45, and the glue removal mechanism 6 includes a first scraper 61, a second scraper 62, an inner rod 63, a socket 67, a right-angle hook 68 and a locking block 692. The first scraper 61 and the second scraper 62 are respectively installed on the bottom surface of the end of the fixed sleeve 41 and the bottom surface of the fixed clamp 45. The inner rod 63 is fixed at both ends of the second scraper 62. The two ends of the first scraper 61 are provided with sockets 67 that cooperate with the inner rod 63. The right-angle hook 68 is slidably connected to the inside of the socket 67, and the inner rod 63 contacts the bottom end of the right-angle hook 68. The locking block 692 is slidably connected to the inside of the socket 67, and the locking block 692 is engaged with the inner rod 63.

[0050] Place the laser-cut battery pack into the softening tank 1, pour warm water of 50℃ to 60℃ and soak for a certain period of time, and wait for the polyurethane glue to soften. Then the user installs the positioning mechanism 2, and manually pushes the positioning mechanism 2 to insert the partition mechanism 3 into the polyurethane glue. The partition mechanism 3 is close to each battery cell 9 in the first row, which not only increases the spacing between adjacent battery cells 9, but also can separate most of the polyurethane glue adhered to the battery cells 9. After installing the positioning mechanism 2, the entire device is immersed in water. After releasing the hand, the floating plate 23 rises due to the buoyancy of the water. By adjusting the coordination of the rack 24 and the adjustment gear 25, and the coordination of the adjustment column 26 and the displacement bar 35, the fixing mechanism 4 moves down and the inner support plate 34 slides into the inside of the positioning bar 21. The fixing mechanism 4 moves down, and the loosening mechanism 5 in the bottom groove 42 can be sleeved on the top of the battery cell 9. The sliding of the inner support plate 34 can release the resistance to the adjustment pressure plate 32, so that the adjustment pressure plate 32 can slide freely, avoiding preventing the subsequent glue removal mechanism 6 from scraping glue on the surface of the battery cell 9.

[0051] The long rod 48 on the side of the rotating positioning bar 21, through a series of cooperation, can not only push the fixing clamp 45 to clamp the battery cell 9, but also drive the loosening mechanism 5 to shake, thereby driving the battery cell 9 to shake, thereby improving the efficiency of separating the battery cell 9 from the colloid.

Finally, remove the entire device, and the battery cells 9 in the first row will be removed and taken away. Taking advantage of the fact that polyurethane glue is easily softened by heat, the battery pack is put into warm water to soften it, and then the device is used to disassemble the battery cells 9. The whole process is simple and fast. The user only needs to install the positioning mechanism 2, and then rotate and push the long rod 48 to complete the disassembly of the entire row of battery cells 9. The operation is easy, the disassembly efficiency is high, and the disassembly speed is fast. Embodiment 2

The connecting rack 46 and the splicing rack 46 on the fixing clamp 45 are meshed and connected, a fixing hook 66 is fixed to the bottom of the sliding block 64, and the fixing hook 66 is engaged and connected with the high end of the right-angle hook 68 inside the first scraper 61, a fourth spring 69 is sleeved on the right-angle hook 68, a fifth spring 691 is installed inside the first scraper 61, and the locking block 692 resists the fifth spring 691, and the side of the fixing hook 66 and the side of the locking block 692 are provided with a locking rack 693, and the locking gear 694 is meshed and connected with the locking rack 693.

[0059] The fixed clip 45 slides while driving the second scraper 62 to move synchronously. Before the fixed clip 45 hits the battery cell 9, the splicing racks 46 at both ends of the fixed clip 45 have driven the sliding block 64 to slide in the bottom groove 42 through the splicing gear 65 and the other splicing rack 46 on the sliding block 64. The fixed hook 66 fixed at the bottom of the sliding block 64 is inserted into the first scraper 61. When the sliding block 64 slides, it drives the first scraper 61 to approach the battery cell 9. When the fixed clip 45 hits the battery cell 9, the two ends of the first scraper 61 hit the two ends of the second scraper 62, and the inner rod 63 is inserted into the insertion hole 67. The first scraper 61 and the second scraper 62 form a complete ring. The insertion of the inner rod 63 into the insertion hole 67 will push the right-angle hook 68 to slide, and the right-angle hook 68 is separated from the fixed hook 66, and the fourth spring 69 is compressed.

[0060] When the lifting screw 47 drives the glue removal mechanism 6 to descend, the sliding block 64 does not move, and the fixed hook 66 gradually slides out of the first scraper 61. Through the cooperation of the locking rack 693 and the locking gear 694 on the side of the fixed hook 66 and the side of the locking block 692, the locking block 692 is driven to descend, the fifth spring 691 is extended, and the locking block 692 is engaged and connected with the inner rod 63, so that the first scraper 61 and the second scraper 62 are stably connected. During the descent of the degumming mechanism 6, the first scraper 61 and the second scraper 62 always contact the surface of the battery cell 9, and can scrape off the colloid on the surface thereof, which not only ensures the efficient separation of the battery cell 9 and the colloid, but also cleans the surface of the battery cell 9. Moreover, during the descent of the degumming mechanism 6, since the adjusting pressure plate 32 contacts the side of the battery cell 9 and can slide freely, when the first scraper 61 and the second scraper 62 slide down and contact the adjusting pressure plate 32, the adjusting pressure plate 32 can be pressed into the support plate 31, thereby preventing the adjusting pressure plate 32 from blocking the first scraper 61 and the second scraper 62 from sliding downward. When the glue removal mechanism 6 is reset (the first scraper 61 contacts the bottom of the fixed sleeve 41 again), the fixed hook 66 is reinserted into the first scraper 61, and the locking block 692 is separated from the inner rod 63 by the cooperation of the locking rack 693 and the locking gear 694 again. During the process of the second scraper 62 returning to drive the inner rod 63 to be pulled out from the insertion hole 67, the fourth spring 69 pushes the right-angle hook 68 to reset, and the right-angle hook 68 is re-engaged with the fixed hook 66, so that the first scraper 61 is firmly installed at the bottom of the fixed sleeve 41. Embodiment 5

[0061] This embodiment is an explanation based on the embodiment 1. For details, please refer to Figure 1-Figure 14The second scraper 62 is provided with a cutting mechanism 7, which includes a sliding box 71, a sixth spring 72, a slider 73, a cutting blade 74, a side box 75, a seventh spring 76, a collision column 77, a locking column 78 and a locking groove 79. The sliding box 71 is fixed to the back of the second scraper 62, and the sixth spring 72 is installed in the sliding box 71. The slider 73 is slidably connected to the sliding box 71, and the slider 73 is connected to one end of the sixth spring 72. The cutting blade 74 is fixedly connected to the slider 73. , and there is a notch on the cutting blade 74 that is adapted to the lifting screw 47, side boxes 75 are fixed on both sides of the sliding box 71, and a seventh spring 76 is installed inside the side box 75, the impact column 77 is slidably connected in the side box 75, and the bottom end of the impact column 77 is lower than the bottom of the cutting blade 74, the bottom end of the seventh spring 76 is installed on the top surface of the impact column 77, the locking column 78 is fixed to the side of the impact column 77, the locking groove 79 is fixed to the back of the cutting blade 74, and the locking column 78 is engaged with the locking groove 79.

[0062] When the degumming mechanism 6 drives the cutting mechanism 7 to move to the bottom of the battery cell 9, the collision post 77 slides upward due to the impact with the top surface of the battery box 8, compressing the seventh spring 76 inside the side box 75 while driving the locking post 78 to disengage from the lock slot 79. After losing the restriction, under the push of the sixth spring 72, the slider 73 slides quickly in the sliding box 71, popping out the cutting blade 74, and the cutting blade 74 slides over the bottom of the battery cell 9 to scrape off the colloid at the bottom, and the battery cell 9 is completely separated from the colloid.

[0063] This embodiment also discloses a method for disassembling a battery pack, comprising the following steps:

[0064] S1: Use laser cutting equipment to horizontally cut the battery pack from the bottom of the side, then remove the upper part of the battery pack, ensure that the bottom plate of the battery pack is flat, and then put the cut battery pack into the softening tank 1, and then pour a certain volume of water with a temperature of 50 degrees Celsius to 60 degrees Celsius into the softening tank 1 and soak for a period of time;

[0065] S2: After the polyurethane glue for fixing the battery cells is softened, starting from one side of the battery pack, first install the positioning mechanism 2, so that the partition mechanism 3 separates each adjacent battery cell, loosens the floating plate 23, and uses the buoyancy of water to make the floating plate 23 rise, thereby driving the fixing mechanism 4 to descend and cover the top of each battery cell;

[0066] S3: Rotate the long rod 48 to allow the fixing clamp 45 to clamp the battery cell. While clamping the battery cell, the loosening mechanism 5 drives the battery cell to shake, and the second scraper 62 approaches the first scraper 61;

[0067] S4: After the fixation is completed, the glue removal mechanism 6 contacts the surface of the battery cell, pushes the long rod 48 and then rotates the long rod 48, the glue removal mechanism 6 descends, and scrapes off the residual colloid on the surface of the battery cell. When the glue removal mechanism 6 reaches the bottom of the battery cell, the cutting blade 74 pops out, scrapes off the adhesive colloid at the bottom of the battery cell, and completely separates the battery cell from the polyurethane glue;

[0068] S5: Remove the positioning mechanism 2, and the device will take away the separated battery cells together.

[0069] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
