Description

Technical Field

[0001] The present invention relates to the technical field of battery pack disassembly, and in particular to a device for disassembling waste power battery packs of new energy vehicles. Background Art

[0002] With the popularity and development of electric vehicles, the recycling and reuse of waste power batteries has become an important issue. Power batteries are also called power battery packs. In addition to battery cells, power battery packs also include power control modules and cooling systems, which are all installed in the power battery packs. When recycling waste power battery packs, the waste power battery packs must first be disassembled and the battery cells and other components inside them must be recycled.

[0003] At present, when dismantling and recycling waste power battery packs of new energy vehicles, it is necessary to first open the top cover of the battery pack shell, and then take out the battery cell module clips in the battery pack, and then sort and crush the battery cell materials, shells, and positive and negative battery plates. Before dismantling, a series of pretreatment processes are required, including battery pack weighing, discharging, and transportation, to ensure the safety of operators during dismantling and avoid short circuits and electrolyte leakage in the battery pack. The shell of the waste battery pack will cause rust at the screw connection between the top cover and the shell in a humid environment, and the inner wall of the top cover will be bonded to the insulation sheet with strong glue, making it difficult to pry open and remove the top cover when manually dismantling it. In addition, the shapes of the battery cell modules in the battery packs of different cars are different, and it is difficult for existing dismantling equipment to automatically core different types of battery packs.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The hydraulic cylinder 2 in the cover removal mechanism will drive the ladder frame to descend so that the frame can be located outside the battery pack, and then the output end of the driving motor 2 will drive the sprocket to rotate, thereby driving the chain to roll inside the frame, so that the chain can drive the connecting seat and the rotating cover to move around the battery pack shell, and the arc spring can squeeze the abutting wheel at the end of the rotating cover to roll against the side wall of the battery pack shell, thereby driving the saw blade in the rotating cover to cut the side wall according to the shape of the battery pack shell, and after cutting the side wall of the battery pack shell, it is convenient to pry open and remove the top cover of the shell, and there is no need to rotate and remove the rusty bolts at the connection between the top cover and the shell, and the top cover is removed by directly separating the battery pack shell, and the cutting unit can cut battery pack shells of various shapes by moving and cutting along the edge, so that the disassembly device has a wide range of uses.

[0019] 2. The cylinder can drive the moving frame to slide on the frame, thereby driving multiple lifting seats to move to the edge below the connection between the top cover and the outer shell. The output end of the servo motor can drive the reciprocating screw to rotate, thereby driving the lifting plate to reciprocate along the limit rod. When the lifting plate rises to the highest end, the moving plate will push the conductive plate to rotate, so that it is separated from the power-on plate. Then, the electromagnet loses its attraction to the counterweight iron block after power failure, so that the counterweight iron block falls down under gravity, so that the counterweight iron block will fall on multiple steel wire ropes. The impact force generated will drive the multiple steel wire ropes to slide on the fixed pulley, and the end of the steel wire rope will drive the lifting seat to rise rapidly, thereby driving the end of the lifting seat The prying hook can violently impact the edge of the top cover from bottom to top, so as to facilitate the prying of the top cover. When the reciprocating screw drives the driving seat to descend, it will drive the lifting plate to press down the counterweight iron block. Therefore, under the continuous squeezing of the wire rope, the end of the wire rope gradually drives the lifting seat to rise, so that multiple prying hooks will lift the cut shell top cover. After the bottom of the electromagnet contacts the top of the counterweight iron block, the counterweight iron block is driven to the top under the action of magnetic attraction. Through reciprocating impact and jacking of the edge of the top cover, the top cover with strong adhesion can be disassembled from the battery pack shell. The disassembly equipment can automatically cut and disassemble the battery pack top cover, reducing the labor intensity of the disassembly personnel.

[0020] 3. The gear column is driven to rotate by a driving motor, thereby driving the moving platform to slide on two T-shaped slide rails, and the battery pack after the top cover is removed is driven by the moving platform to move to the position of the coring mechanism, and the cross clamping arm is driven by the mechanical arm to extend into the battery pack, and then the pressurized air pump is used to deliver high-pressure air to the installation cylinder, thereby driving the piston column to slide downward under the action of air pressure, and the linkage plate drives the connecting rod at the bottom to rotate, so that the connecting rod can drive the two cross clamping arms to rotate relative to each other to clamp the battery module, and then the mechanical arm and the rotating column are used to complete the coring operation, and the top of the installation cylinder and the internal threaded sleeve are rotated and screwed together, so that different clamping arms can be replaced as needed at the bottom of the connecting seat, so as to facilitate automatic coring of battery modules of different sizes.

[0045] The cylinder (214) can drive the moving frame (213) to slide on the frame (204), thereby driving the plurality of lifting seats (220) to move to the lower edge of the connection between the top cover and the outer shell, and the output end of the servo motor (237) can drive the reciprocating screw rod (236) to rotate, thereby driving the lifting plate (228) to reciprocate along the limit rod (225). When the lifting plate (228) rises to the highest end, the abutting plate (229) will abut against the lifting plate (228). The conductive plate (234) rotates to separate the conductive plate (234) from the power supply plate (233). Then, the electromagnet (230) loses its attraction to the counterweight iron block (227) after power is cut off, so that the counterweight iron block (227) falls freely downward under gravity, and the counterweight iron block (227) falls on the plurality of steel wire ropes (219). The impact force generated drives the plurality of steel wire ropes (219) to slide on the fixed pulley (217), and the ends of the steel wire ropes (219) drive the lifting and lowering The seat (220) rises rapidly, thereby driving the lid prying hook (221) at the end of the lifting seat (220) to violently impact the edge of the top cover from bottom to top, thereby facilitating the lid prying process on the top cover. When the reciprocating screw rod (236) drives the driving seat (231) to descend, it drives the lifting plate 228 to press down the counterweight iron block (227). Therefore, under the continuous squeezing of the wire rope (219), the end of the wire rope (219) gradually drives the lifting seat (220) to rise. , so that the multiple cover prying hooks (221) lift the cut outer shell top cover, and after the bottom of the electromagnet (230) contacts the top of the counterweight iron block (227), the counterweight iron block (227) is driven to the top under the effect of magnetic attraction, and the top cover with strong adhesion can be disassembled from the battery pack outer shell by reciprocating impact and pushing the edge of the top cover, and the disassembly equipment can automatically cut and disassemble the battery pack top cover, thereby reducing the labor intensity of the disassembly personnel.

The connecting plate (311) drives the connecting rod (312) at the bottom to rotate, so that the connecting rod (312) can drive the two cross clamping arms (314) to rotate relative to each other to clamp the battery module, and then the mechanical arm (303) and the rotating column (302) are used to complete the coring operation.
