Description

Technical Field

[0001] This utility model relates to the field of battery recycling, specifically to a battery pack disassembly line. Background Technology

[0002] The purpose of initial discharge of the battery pack is to better realize the physical recycling of materials. The fundamental reason is that the discharge action can cause most of the lithium ions to return from the negative electrode to the positive electrode. A large part of the value of the positive electrode sheet comes from the lithium content, and the return of lithium ions to the positive electrode is more conducive to the stability of the material structure.

[0003] Discharging a battery pack requires first disassembling it into cell modules, then calculating the number of cells in each module by measuring the voltage, and finally discharging the cell modules by connecting them to a cement resistor. In current technology, the equipment used for disassembling battery packs is relatively dispersed, resulting in frequent turnover and low overall efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a battery pack disassembly line to overcome the shortcomings of the prior art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A battery pack disassembly line includes: a battery pack conveyor line, a cell module conveyor line, a cell module transfer mechanism, and a cell stacking mechanism arranged sequentially along the product flow direction. The battery pack conveyor line has a tooling plate. A cover removal and handling mechanism and multiple first manual online disassembly stations are arranged sequentially along the product flow direction outside the battery pack conveyor line. The cell modules in the battery pack on the battery pack conveyor line are transported to the cell module conveyor line by the cell module handling mechanism. Multiple cell module terminal milling machines are arranged sequentially along the product flow direction outside the cell module conveyor line.

[0006] The beneficial effects of this utility model are:

[0007] The battery pack conveyor line first sends the battery pack to the cover removal mechanism. The cover removal mechanism first removes the cover screws in the battery pack, and then removes the cover from the battery pack.

[0008] After the battery pack with the top cover removed is sent to the first manual online disassembly station, the copper busbars, wire harnesses, etc. are first manually disassembled online, and then the module screws and related fasteners are manually disassembled online.

[0009] Since the battery pack was partially disassembled manually online first, the cell modules in the battery pack on the battery pack conveyor line can be transported to the cell module conveyor line by the cell module handling mechanism. Since the terminals of some cell modules are welded, it is inconvenient to manually disassemble the cells. In order to improve work efficiency, the cell modules on the cell module conveyor line are sent to multiple cell module terminal milling machines, and then the cell module terminal milling machines mill the terminals of the cell modules to quickly eliminate the solder joints.

[0010] After the battery cell module terminal milling machine mills the battery cell module terminal, it is sent to the battery cell module transfer mechanism, where the battery cell module is disassembled. Then it is transferred to the battery cell stacking mechanism, where the disassembled battery cell module is finally stacked.

[0011] By organizing all the equipment into a production line, turnaround time can be reduced, disassembly efficiency can be improved, and manual handling can be reduced, thus lowering labor intensity.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, the top cover removal mechanism includes: a robot, a detachable screw removal fixture and a vacuum suction cup holder mounted on the robot.

[0014] The further beneficial effects of adopting the above are as follows: During disassembly, the screws are removed first, and then the top cover is removed. Therefore, the robot is first equipped with a screw disassembly fixture, and the position of the screw disassembly fixture is adjusted. Then, the screw disassembly fixture disassembles the screws that fix the top cover in the battery pack. After the screws are disassembled, the robot removes the screw disassembly fixture, and then loads a vacuum suction cup frame. The robot, together with the vacuum suction cup frame, removes the top cover from the battery pack, forming an automatic disassembly and transportation, reducing manual intervention and labor intensity.

[0015] Furthermore, the cell module terminal milling machine includes: a worktable, a Y-axis module on the worktable, a cell module clamping mechanism on the Y-axis module, an X-axis module mounted above the Y-axis module, a Z-axis module on the X-axis module, a power mechanism on the Z-axis module, and a milling cutter mounted on the power mechanism.

[0016] The further beneficial effects of the above are as follows: the battery cell module is placed on the battery cell module clamping mechanism, and then the Y-axis module is sent to the corresponding position. Then the X-axis module and Z-axis module work together to move the power mechanism to the corresponding position. The power mechanism drives the milling cutter to rotate at high speed, thereby milling the terminal post in the battery cell module to quickly eliminate the solder joint.

[0017] Furthermore, the cell module transfer mechanism includes: a diversion mechanism arranged at the discharge end of the cell module conveyor line, the diversion mechanism having at least two discharge ends, each discharge end of the diversion mechanism having a second manual online disassembly station, and a belt conveyor arranged between the second manual online disassembly station and the cell stacking mechanism.

[0018] The further beneficial effects of the above-mentioned method are as follows: After being processed by the cell module terminal milling machine, the cell modules are sent to the splitting mechanism, which then splits the cell modules and sends them to the second manual online disassembly station. At the second manual online disassembly station, the cell modules are disassembled and placed on the conveyor belt, which then sends them to the cell stacking mechanism. This allows for automatic splitting of the cell modules, ensuring that each of the second manual online disassembly stations has products to process.

[0019] Furthermore, the diversion mechanism includes: a non-powered roller line, a flow strip arranged between the discharge end of the non-powered roller line and the second manual online dismantling station, a telescopic mechanism arranged below the non-powered roller line, the telescopic direction of the telescopic mechanism being perpendicular to the rotation axis of the rollers in the non-powered roller line; the telescopic mechanism is fixed to a pusher frame, the upper end of the pusher frame extending into the gap between the rollers of the non-powered roller line.

[0020] The further beneficial effects of adopting the above are as follows: the telescopic mechanism drives the pusher to move back and forth to send the battery cell modules on the unpowered roller line to the flow bar, and then flow through the flow bar to the second manual online disassembly station. The structure is simple and can automatically realize the diversion.

[0021] Furthermore, the battery cell modules on the battery cell module conveyor line are transported to the battery cell module terminal milling machine by the battery cell module handling mechanism.

[0022] The further beneficial effects of adopting the above methods are: it can reduce manual handling and lower labor intensity.

[0023] Furthermore, the battery cell module handling mechanism includes: an electric hoist and a battery cell module clamp mounted on the electric hoist.

[0024] The further beneficial effects of adopting the above are as follows: first, the battery cell module is clamped by the battery cell module clamp, and then the battery cell module on the clamp and the battery cell module are hoisted by the electric hoist. The structure is simple and the operation is convenient.

[0025] Furthermore, a feeding mechanism is arranged at the feeding end of the battery pack conveyor line.

[0026] The further beneficial effect of adopting the above is that the manual operation of the feeding mechanism to feed the battery pack can reduce labor intensity.

[0027] Furthermore, turnover trolleys are arranged at the loading and unloading ends of the battery pack conveyor line, the first manual online disassembly station, and the cell module transfer mechanism.

[0028] The further beneficial effect of adopting the above is that materials can be rotated through the turnover trolley. Attached Figure Description

[0034] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0035] Example 1

[0036] like Figure 1 , Figure 2 , Figure 3As shown, a battery pack disassembly line includes: a battery pack conveyor line 1, a cell module conveyor line 2, a cell module transfer mechanism 3, and a cell stacking mechanism 4 arranged sequentially along the product flow direction. The battery pack conveyor line 1 has a tooling plate 5, on which the battery pack is placed and then moves along the conveyor line 1 with the tooling plate 5. Outside the battery pack conveyor line 1, along the product flow direction, a top cover removal mechanism 6 and multiple first manual online disassembly stations 7 are arranged sequentially. The first manual online disassembly stations 7 use an equipotential working platform. The battery pack conveyor line 1 first sends the battery pack to the top cover removal mechanism 6, then the top cover removal mechanism 6 removes the top cover screws from the battery pack, and finally removes the top cover from the battery pack. The battery pack with the top cover removed is then sent to the first manual online disassembly station 7, where copper busbars, wire harnesses, etc., are first manually disassembled online, and then module screws and related fasteners are manually disassembled online. Because the battery pack is first manually disassembled online... Partial disassembly has been performed. Therefore, the battery cell modules in the battery pack on battery pack conveyor line 1 can be transferred to battery cell module conveyor line 2 by battery cell module handling mechanism 9. Multiple battery cell module terminal milling machines 8 are arranged sequentially along the product flow direction outside battery cell module conveyor line 2. Since the terminals of some battery cell modules are welded, it is inconvenient to manually disassemble the cells. In order to improve work efficiency, the battery cell modules on battery cell module conveyor line 2 are sent to multiple battery cell module terminal milling machines 8 respectively. Then, the battery cell module terminal milling machines 8 mill the terminals of the battery cell modules to quickly eliminate the weld points. After the battery cell module terminal milling machines 8 mill the terminals of the battery cell modules, they are sent to battery cell module transfer mechanism 3. The battery cell modules are disassembled at battery cell module transfer mechanism 3 and then transferred to battery cell stacking mechanism 4. Finally, the battery cell stacking mechanism 4 stacks the disassembled battery cell modules.

Of course, in actual applications, the CCD camera can be omitted, as long as the product can be accurately placed in the disassembly position each time. During disassembly, the screws are removed first, and then the top cover is lifted. Therefore, the screw removal fixture 620 is first mounted on the robot 610, and its position is adjusted. Then, the screw removal fixture 620 removes the screws that fix the top cover in the battery pack. After the screws are removed, the robot 610 removes the screw removal fixture 620, and then mounts the vacuum suction cup holder 630. The robot 610, together with the vacuum suction cup holder 630, lifts the top cover off the battery pack.

The battery cell module is placed on the battery cell module clamping mechanism 830, and then the Y-axis module 820 moves it to the corresponding position. The X-axis module 840 and the Z-axis module 850 work together to move the power mechanism 860 to the corresponding position. The power mechanism 860 drives the milling cutter 870 to rotate at high speed, thereby milling the terminal in the battery cell module to quickly eliminate the solder joints.
