Description

Technical Field

[0001] The utility model relates to the technical field of battery cell replacement, in particular to a lithium battery module cell replacement device. Background Art

[0002] Lithium battery is a rechargeable battery that uses lithium metal or lithium compounds as the positive electrode material. It has the advantages of high energy density, long cycle life and low self-discharge rate, so it is widely used in electric vehicles, mobile devices, drones, energy storage systems and other fields. After long-term use, lithium batteries need to be replaced, and lithium battery cell replacement means replacing the aging or damaged cells in the battery to restore the battery's function.

[0003] A Chinese patent with publication number "CN212146128U" discloses a new energy battery inspection station, which includes a first inspection station and a second inspection station, the outer sides of the tops of the first inspection station and the second inspection station are fixed with a fixing plate, the tops of the fixing plates are fixed with a motor, the output end of the motor is clamped with a first bevel gear, both ends of the first bevel gear are meshed and connected with a second bevel gear, one end of the second bevel gear is welded with a threaded rod, and a support block is installed on the outer side of the threaded rod and at one end of the second bevel gear. The utility model enables the device to conveniently clamp batteries of different sizes through the cooperation between the motor, the threaded rod and the clamping plate, making clamping and fixing more convenient, and through the mutual cooperation between the connecting extension slot, the connecting plate and the threaded adjustment rod, the device can adjust the placement area according to the actual use situation, greatly improving the scope of application of the device.

[0004] Although the above-mentioned device can assist in positioning, adjusting and clamping during use, it still has certain shortcomings during use. First of all, it can only clamp the lithium battery in a two-way position during use. However, lithium batteries usually have multiple sides. Rectangular lithium batteries are composed of four sides, and arc-shaped or round lithium batteries are more complicated. The above-mentioned device can obviously only position the two sides of the lithium battery. The whole is prone to sliding during the disassembly and replacement of the battery cells, causing the electrolyte and harmful substances inside the battery cells to splash onto the table. On the one hand, it will cause inconvenience to disassembly and maintenance, and on the other hand, it will cause the equipment to be contaminated. It is also easy to adhere to the skin of the maintenance personnel. It can be seen that the existing equipment needs to be improved. Utility Model Content

[0043] The specific working principle is as follows: during use of the device, a lithium battery can be placed on the top of the receiving mesh plate 8, and the second motor 63 is started to drive the threaded rod 62 to rotate. Since the threads at both ends of the threaded rod 62 rotate in opposite directions, the sliding blocks 64 on both sides of the rear track 61 can be driven to slide against each other through the threaded rod 62, and the sliding blocks 64 can assist in driving the clamping plates 71 to slide against each other. The battery module can be initially clamped laterally by the sliding of the clamping plates 71 against each other. After the battery module is clamped, the first motor 76 can be started to run, and the bidirectional screw rod 73 can be driven to rotate by the first motor 76. Since the threads at both ends of the bidirectional screw rod 73 rotate in opposite directions, The two sets of sliding blocks 74 can be driven to slide against each other by the bidirectional screw rod 73, and the sliding blocks 74 can slide against each other, thereby assisting in driving the clamping frame 75 to move relative to each other, and the clamping frame 75 can abut against the other two sides of the fixed battery module to assist in clamping both the front and rear ends of the battery module.

When the device is performing a lithium battery cell replacement process, when the top clamping plate 71 of the receiving mesh plate 8 and the clamping frame 75 are used to clamp the entire outer shell of the lithium battery After fixing, the battery shell is opened manually using disassembly tools such as screws, and then the battery cell is taken out from the battery shell by using a clamp, such as pliers or a manipulator. If the electrolyte in the battery cell accidentally flows out, it can be filtered through the receiving mesh plate 8, and the electrolyte enters the collecting bucket 5 through the receiving mesh plate 8. When the battery cell is replaced, the water pump 91 can be started to pump the water in the collecting bucket 5. The water is transported through the transport pipe rack 92 to assist the water to enter the spray box 93, and sprayed out through the spray nozzle 94 at the bottom of the spray box 93, so that the water can be evenly discharged from the top of the receiving mesh plate 8. It can be rinsed, and the tools used for clamping and disassembly can also be rinsed, so that the receiving mesh plate 8 can be better cleaned, and the electrolyte and harmful substances inside the battery cell can be prevented from adhering to the equipment, and the problem of affecting the disassembly and assembly of the battery cell or causing environmental pollution when the battery cell is replaced again can be avoided. It can play a better cleaning role and avoid the problem of environmental pollution caused by the electrolyte inside the battery cell. At the same time, the activated carbon filter element 10 can be used to assist in filtering the water during the water pump 91 pumping the water, and the activated carbon can be used to assist in filtering the harmful substances contained in the water, so that the equipment can recycle water and has strong protection performance as a whole.
