Description

Technical Field

[0001] The present invention relates to the technical field of power battery equipment, and in particular to a device for automatically disassembling a power battery module. Background Art

[0002] Driven by the new energy vehicle industry, lithium-ion power batteries have been widely used. In 2018, my country's cumulative production and sales of new energy vehicles reached 1.2705 million and 1.2562 million, up 59.92% and 61.74% year-on-year. The life of power batteries is usually 500-2000 cycles. Generally, after 5-8 years of use, the battery capacity is less than 80%. When it does not meet the user's travel needs, it needs to be scrapped. It is predicted that the amount of scrapped power batteries in my country will reach 248,000 tons in 2020, and the problem of power battery recycling is very serious.

[0003] The power battery recycling process includes two major links: battery disassembly and material regeneration. Battery disassembly includes battery pack disassembly, battery module disassembly and battery cell disassembly. The power battery module is composed of several battery cells that are arranged in parallel in series and parallel and then assembled together by wrapping in an outer shell. The traditional power battery disassembly is to cut the outer shell by hand with a cutting machine, and then use a stick to knock the outer shell open to separate the battery cell from the outer shell. The traditional disassembly method has great safety hazards due to the handheld cutting machine, which is very easy to hurt people; at the same time, the cutting depth is not easy to control manually, which can easily cause cutting of the battery cell and cause serious consequences of battery fire and explosion. A large number of burrs will be generated on the cut part of the outer shell after cutting, which can easily cause personal injury and has obvious limitations.

[0034] Working process: Place the power battery module 300 on the cutting platform 100, and the clamping mechanism 200 clamps the front and rear sides of the power battery module 300. At this time, according to the size of the power battery module 300 and the number of single cells, start the first driving component 430, the second driving component 412, and the third driving component 530 to adjust the heights of the first cutting blade 410, the second cutting blade 411, the third cutting blade 510, and the fourth cutting blade 520, and adjust the distance between every two second cutting blades 411. After the adjustment is completed, rotate the cutting blades by means of a motor or a rotary cylinder.

Since the retaining teeth 921 are provided, the negative battery cells will be blocked by the retaining teeth 921. When the positive battery monomer is detected to have arrived in front of the first propulsion mechanism 930, the fourth cylinder 931 is activated to move the first push plate 932 forward, so that the positive battery monomer is transferred to the place where the positive battery monomer is stored. When the positive battery monomer is pushed by the second push plate 942, the sorting baffle 920 is manually or by a motor to move the negative battery monomer. When the negative battery monomer is detected to have arrived in front of the second propulsion mechanism 940, the fifth cylinder 941 is activated to move the second push plate 942 backward, so that the negative battery monomer is transferred to the place where the negative battery monomer is stored. The use of the sorting device 900 for classified storage avoids safety hazards such as short circuits between battery monomers during storage and transportation.
