Of course, in other embodiments, only one cutting station may be provided on the battery disassembly and recovery device.

In some embodiments, the cutting mechanism 30 includes a fixing frame 31, a driving mechanism 32 and a cutting assembly 33, the fixing frame 31 is provided with a carrying platform 311 and a blanking space 313 positioned at one side of the carrying platform 311, and a cutting side 312 is formed at one side of the carrying platform 311 close to the blanking space 313; the driving mechanism 32 is mounted on the fixed frame 31; the cutting assembly 33 is movably mounted on the fixing frame 31 and has a cutting edge 334 facing the blanking space 313, the cutting assembly 33 is connected with the driving mechanism 32, so that the driving mechanism 32 drives the cutting assembly 33 to move relative to the fixing frame 31 in a direction away from or close to the blanking space 313, and the cutting edge 334 and the cutting side edge 312 form a cutting structure.

Specifically, the cutting edge 334 can extend into the blanking space 313 from the cutting side 312, in operation, the battery assembly can be moved onto the carrying platform 311 by the clamping mechanism 40, and the battery assembly extends out relative to the cutting side 312 to be located above the blanking space 313 and below the cutting edge 334, when the cutting assembly 33 is driven to move towards the blanking space 313 by the driving mechanism 32, the extending part of the battery shell relative to the cutting side 312 can be cut, and the cut part directly falls into the blanking space 313. A recovery mechanism may be provided on the base 10 to recover the cut-out portion of the battery case. And after the side of the battery case is cut off, the driving mechanism 32 drives the cutting assembly 33 to move in the reverse direction to wait for the next cutting step. When a plurality of cutting stations are provided on the base 10, different side portions of the battery case can be cut through different cutting stations, and when only one cutting station is provided on the base 10, the battery assembly can be rotated through the carrying mechanism 60 after one side of the battery case is cut, and the rest side portions are cut off until the battery unit is separated from the battery case conveniently. The drive mechanism 32 may be a pneumatic cylinder or an electric cylinder.

According to the technical scheme, the object bearing table 311 and the blanking space 313 positioned at one side of the object bearing table 311 are arranged on the fixing frame 31, the cutting side edge 312 is formed at one side, close to the blanking space 313, of the object bearing table 311, and the cutting assembly 33 capable of moving relative to the object bearing table 311 is arranged on the fixing frame 31, so that the cutting edge 334 of the cutting assembly 33 and the cutting side edge 312 form a cutting structure. In this way, when the battery pack is operated, the battery pack is moved to the carrying platform 311, and after the battery pack extends out relative to the cutting side edge 312, the driving mechanism 32 drives the cutting assembly 33 to move towards the blanking space 313, so that the extending part of the battery case relative to the cutting side edge 312 can be cut off.

In some embodiments, the cutting assembly 33 is mounted above the carrying platform 311 and is slidably mounted on the fixing frame 31 along the up-down direction. That is, when the battery pack is correctly placed above the carrying table 311 during operation, the driving mechanism 32 drives the cutting assembly 33 to move downward, so that the portion of the battery case extending from the cutting side 312 can be cut off. This makes it possible to provide the driving mechanism 32 and the cutter assembly 33 with the space above the stage 311, and to reduce the size of the cutter mechanism 30 in the horizontal direction. Of course, in other embodiments, the cutting assembly 33 may also be rotatably mounted to the fixing base 331.

In some embodiments, the cutting edge 334 extends obliquely to the up-down direction. That is, the cutting edge 334 extends gradually downward and obliquely in a direction in which one end points to the other end, and the cutting edge 334 is inclined with respect to the cutting side 312. When the cutter 333 moves downward, one end of the cutting edge 334 is firstly in contact with the battery case, and the rest part gradually contacts with the battery case along with the downward movement of the cutter 333. Thus, when the cutting edge 334 just begins to contact the battery case, the contact area between the cutting edge and the battery case is small, and part of the battery case is easier to cut, so that the side part of the battery case is convenient to cut off later. Of course, in other embodiments, the cutting edge 334 may be disposed parallel to the cutting side 312.

In some embodiments, the cutting mechanism 30 further includes a pressing mechanism 34, where the pressing mechanism 34 is mounted above the carrying table 311, and has a pressing member 342 moving in the up-down direction, and the pressing member 342 is used to press the battery assembly onto the carrying table 311. Specifically, after the battery assembly is placed on the carrying platform 311 and the side portion of the battery shell extends out relative to the cutting side edge 312, the battery assembly is pressed on the carrying platform 311 through the pressing piece 342, and then the cutting procedure is performed, so that the risk of shifting the battery assembly in the cutting process can be avoided, the battery assembly can be stably placed in the cutting process, and the cutting effect is improved. And thus the pressing mechanism 34 can be provided by utilizing the space above the carrying table 311, and the size of the cutting mechanism 30 in the horizontal direction can be reduced. Of course, in other embodiments, clamping structures may be disposed on both sides of the carrying platform 311 for clamping the battery assembly.

In some embodiments, the pressing mechanism 34 includes two pressing cylinders 341, where the two pressing cylinders 341 are mounted on the fixing frame 31 and are distributed at intervals along the length direction of the cutting side 312, and a piston rod of each pressing cylinder 341 is provided with a pressing member 342. That is, the battery assembly may be simultaneously compressed by the two compressing members 342, so that the compressing effect on the battery assembly may be improved when the battery assembly of a larger size is faced.

In some embodiments, the cutting mechanism 30 further includes a positioning mechanism 35, where the positioning mechanism 35 is located above the blanking space 313 and is movably mounted on the fixing frame 31 along the distribution directions of the carrying platform 311 and the blanking space 313, and has a positioning position adjacent to the cutting side edge 312 and an avoidance position far away from the cutting side edge 312, and the positioning mechanism 35 has an abutment structure 351 disposed towards the carrying platform 311, where the abutment structure 351 is located below the cutting assembly 33 and is used for abutting a portion of the battery assembly to be cut extending from the cutting side edge 312, and where the abutment structure 351 is disposed in a dislocation manner with the cutting assembly 33.

Specifically, the positioning mechanism 35 includes a positioning cylinder 352 and an abutting structure 351 mounted on a piston rod of the positioning cylinder 352, and the positioning cylinder 352 is mounted on the fixing frame 31. The positioning position and the avoiding position can be set in advance, when the battery shell cutting device works, the positioning mechanism 35 can be positioned at the positioning position, so that the battery shell stretches out relative to the cutting side edge 312 and can be positioned at a proper position to be cut when the battery shell is abutted to the abutting structure 351, the battery assembly can be pressed on the carrying table 311 through the pressing assembly, the positioning mechanism 35 can be moved to the avoiding position, and then the battery shell is cut through the cutting assembly 33. Therefore, the battery assembly can be accurately positioned, and the condition that the battery assembly excessively stretches into is avoided. Of course, in other embodiments, positioning structures may be provided on the table 311 or sensors or the like may be provided on the cutting assembly 33. In addition, in other embodiments, the positioning mechanism 35 includes an electric cylinder and an abutment structure 351 mounted to the electric cylinder pushrod.

The risk that the clamping arms 43 are deformed or even damaged due to excessive deformation of the battery assembly in the cutting process can be reduced, and meanwhile, the battery assembly in the cutting process can be limited through the two clamping arms 43, so that the battery assembly is prevented from being shifted in the cutting process, and the battery assembly is not clamped in place after being cut.

In some embodiments, the connecting frame 41 includes a first frame 412, a second frame 413 and a lifting cylinder 42, the upper end of the first frame 412 is slidably mounted on the mounting frame 20, the lifting cylinder 42 is mounted on the lower end of the first frame 412, the piston rod of the lifting cylinder 42 extends downward, the second frame 413 is mounted on the piston rod of the lifting cylinder 42, and both clamping arms 43 are mounted on the second frame 413. So make the height of two clamping arms 43 can be adjusted according to the high of battery pack to make two clamping arms 43 can better centre gripping battery pack, promoted fixture 40's suitability.

In some embodiments, the mounting frame 20 is provided with a sliding mechanism; the carrying mechanism 60 comprises a sliding frame 61 and a plurality of pushing components 63, the sliding frame 61 is slidably mounted on the sliding mechanism along the conveying direction, the pushing components 63 are movably mounted on the sliding frame 61 along the up-down direction, and the pushing components 63 are sequentially distributed along the conveying direction and are correspondingly arranged with a plurality of cutting stations.

The number of the pushing components 63 is consistent with that of the cutting stations, and a clamping component is arranged on the base 10 corresponding to each cutting station, so that the cutting mechanisms 30 of the plurality of cutting stations cut the battery components at the same time during operation. Specifically, after the battery disassembly and recovery device is started, the first battery component enters the battery conveying area 11 from the feeding end 101 (which can be moved by the carrying mechanism 60 or can be conveyed by another conveying mechanism), and when the first battery component moves to a position close to the first cutting station (the cutting station closest to the feeding end 101), the first battery component can be clamped by the clamping mechanism 40 and moved to the cutting station for cutting. The clamping mechanism 40 then clamps the battery pack for movement to the battery transfer area, where one of the pushing assemblies 63 pushes the cut battery pack toward the second cutting station (adjacent to the first cutting station described above) while the second battery pack enters the battery transport area 11 from the feed end 101 and moves toward a position adjacent to the first cutting station. When the first battery component moves in place, the clamping component corresponding to the first cutting station clamps the second battery component to move to the first cutting station for cutting, and the clamping component corresponding to the second cutting station moves to the second cutting station for cutting. When the first and second battery packs are cut at the corresponding cutting stations and moved to the battery transfer area by the corresponding clamping assemblies, one of the pushing assemblies 63 pushes the first battery pack to move toward the next cutting station or the battery unit separating station, and the other pushing assembly 63 pushes the second battery pack to move toward the second cutting station, and then the sequentially entered battery packs repeat the above processes.

The sliding frame 61 can reciprocate along the conveying direction, that is, after the pushing component 63 pushes the battery component to reach the position of the next cutting station, the pushing component 63 moves up relative to the sliding frame 61, so that the pushing component 63 is spaced apart from the battery component in the up-down direction, at this time, the sliding frame 61 moves along the opposite direction of the conveying direction to move to the position of the previous cutting station, when the battery after the cutting of the previous cutting station is retracted to the battery conveying area 11, the pushing component 63 moves down relative to the sliding frame 61, so as to push the battery component to move towards the next cutting station, and the above steps are repeated. Or the sliding mechanism is arranged in a ring shape, and a plurality of pushing components 63 circularly slide on the sliding mechanism.

By being provided with the slide mechanism on the mounting frame 20, the slide frame 61 of the carrying mechanism 60 is slidably mounted on the slide mechanism along the conveying direction, a plurality of pushing components 63 of the carrying mechanism 60 are movably mounted on the slide frame 61 along the up-down direction, and the plurality of pushing components 63 are sequentially distributed along the conveying direction and are correspondingly arranged with a plurality of cutting stations. After each battery pack after cutting by the cutting stations is moved to the battery conveying area, the plurality of battery packs can be pushed to move towards the respective next cutting station through the plurality of pushing assemblies 63, so that the conveying speed of the battery packs can be improved, the moving consistency of each battery pack among the plurality of cutting stations is high, and the disassembling efficiency of the battery packs is greatly improved.

In some embodiments, each pusher assembly 63 has two pusher plates 632 extending toward the base 10, the two pusher plates 632 of each pusher assembly 63 being spaced apart along the conveying direction to form a receiving space between the two pusher plates 632 into which the power supply assembly is placed. That is, when the pushing assembly 63 moves down in a relative sliding manner, the two pushing plates 632 are respectively arranged at the front side and the rear side of the battery assembly, so that when the pushing assembly 63 moves along the conveying direction, the battery assembly can be pushed to move by the pushing plates 632 at the rear side of the battery assembly. While the push plate 632 at the front side of the battery pack can limit the battery pack from sliding forward, so that the battery pack can be accurately moved to the corresponding position. And thus the structure of the pushing assembly 63 can be simplified. Of course, in other embodiments, the pushing assembly 63 may also be configured as a jaw, and the battery assembly is held by the jaw for translational movement in the conveying direction.

In some embodiments, the carriage 61 is provided with a plurality of first cylinders 62, and the plurality of first cylinders 62 are sequentially distributed along the conveying direction, and each pushing component 63 is correspondingly mounted on a piston rod of one first cylinder 62. Specifically, the pushing assembly 63 includes a fixing plate 631 and two pushing plates 632, the two pushing plates 632 are mounted on the fixing plate 631 at intervals, and the fixing plate 631 is mounted on the piston rod of the first cylinder 62. This allows each pushing assembly 63 to be independently driven by one first cylinder 62, which may promote flexibility in the installation of multiple pushing assemblies 63. Of course, in other embodiments, multiple pushing assemblies 63 may be driven to move up and down synchronously by one first cylinder 62.

When the number of the cutting mechanisms 30 is three, the first cutting mechanism 30, the second cutting mechanism 30 and the third cutting mechanism 300 are sequentially and alternately distributed along the direction of the feeding end 101 pointing to the discharging end 102. The first cutting mechanism 30, the second cutting mechanism 30, and the third cutting mechanism 300 may have the same structure or different structures; optionally, the first, second and third cutting mechanisms 30, 300 each have a cutting assembly 33, a support table and hold down mechanism 34.

The first cutting mechanism 30 is used for cutting a first side of the battery case, and the second cutting mechanism 30 is used for cutting a second side of the battery case opposite to the first side.

Specifically, the side of the battery conveying area 11 away from the first cutting mechanism 30 and the side of the battery conveying area 11 away from the second cutting mechanism 30 are both provided with the clamping mechanism 40.

Thus, the first side part of the battery shell can be cut through the first cutting mechanism 30, the second side part opposite to the first side part on the battery shell is cut through the second cutting mechanism 30, the battery shell is cut through the first cutting mechanism 30 and the second cutting mechanism 30 in a pipeline type, the residence time of the battery assembly at each cutting mechanism 30 is reduced while the cutting station is increased, the disassembly efficiency of the battery assembly is improved, and the battery shell can be set according to actual conditions due to the different positions of the first cutting mechanism 30 and the second cutting mechanism 30.

In some embodiments, the battery disassembly and recycling apparatus further includes a third cutting mechanism 300, the third cutting mechanism 300 being disposed between the second cutting mechanism 30 and the discharge end 102 and being located in the battery conveying area 11, the third cutting mechanism 300 being configured to cut a third side portion of the battery case located between the first side portion and the second side portion. Specifically, the third cutting mechanism 300 is disposed toward the feed end 101 such that the battery pack transferred from the battery conveying region 11 can be moved directly toward the third cutting mechanism 300 without additionally providing a clamping member to clamp the battery pack in the battery conveying region 11 to move to the third cutting mechanism 300. Thus, the first cutting mechanism 30, the second cutting mechanism 30 and the third cutting mechanism 300 are used for respectively cutting the three sides of the square battery assembly, so that the subsequent detachment of the battery unit from the battery shell can be more convenient. And can select to cut off two lateral parts or three lateral parts of the battery shell according to the size of the battery assembly or the difficulty degree of battery unit split like this, the compatibility is wide. Of course, in other embodiments, only the first cutting mechanism 30 and the second cutting mechanism 30 may be provided.

In some embodiments, the third cutting mechanism 300 is provided with a cutting area 301 and a conveying channel 302, and the cutting area 301 and the conveying channel 302 are sequentially distributed along the feeding end 101 toward the discharging end 102, so that the battery case after the third side portion is cut off by the cutting area 301 is conveyed from the conveying channel 302 to the discharging end 102. Specifically, a blanking gap 303 is disposed between the cutting area 301 and the conveying channel 302, and the third side portion of the battery case cut by the cutting assembly 33 of the third cutting mechanism 300 can fall into the blanking space 313 below from the blanking gap 303, where the width of the blanking gap 303 is smaller than the overall size of the battery assembly, so as to avoid falling into the blanking gap 303 when the battery assembly moves towards the conveying channel 302. By providing the third cutting mechanism 300 with the conveying passage 302, the cut battery assembly can be directly moved from the conveying passage 302 toward the discharge end 102. The battery assembly may be moved to the discharge end 102 by a robot, or may be pushed from the conveying path 302 to the discharge end 102 by the carrying mechanism 60.
