Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to battery cell disassembly tooling and battery recycling equipment. Background Art

[0002] With the rapid development of new energy electric vehicles, the use of electric vehicles in the market has gradually increased, and various failure problems have also arisen. Among them, failures caused by battery cells account for the vast majority. When the battery cells are returned to the factory for analysis, it is often necessary to further disassemble the battery cell shell. This disassembly process usually requires professional disassembly personnel to operate, and disassembly accidents occur from time to time. In the mildest case, it may cause a short circuit in the battery cell and a fire. In the worst case, it may cause injuries to the disassembly personnel or even a fire in the disassembly room.

[0003] Currently, the disassembly of the battery cell shell is usually done by professional disassemblers using a ceramic knife to manually draw a circle along the bottom of the battery cell cover, and then using diagonal pliers to break the shell along the line. This method has the following disadvantages: manual marking results in uneven marking, uneven force and inconsistent marking depth, which may scratch the internal battery cell insulation film; during the manual marking process, the ceramic knife tip may slip and accidentally scratch the disassembler's body, causing a safety accident, and the ceramic knife may easily break due to uneven force and bounce to surrounding personnel, posing a safety hazard; disassemblers need to receive professional training before they can use diagonal pliers to break the shell along the marked line. This operation step is not easy for personnel to get started quickly and requires a certain amount of personnel training costs. Utility Model Content

DETAILED DESCRIPTION

[0038] The technical solution of the present application will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0039] Combine the following Figure 1-Figure 5 , describing a battery cell disassembly tool provided in an embodiment of the present application.

[0040] Reference Figure 1 As shown, in the embodiment provided in the present application, the battery cell disassembly tool includes a base 100, a feeding mechanism 200 and a tool 300. The feeding mechanism 200 is arranged on the base 100, and the feeding mechanism 200 and the base 100 rotate in cooperation; the tool 300 is connected to the feeding mechanism 200, and any part of the tool 300 can approach or move away from the base 100 at an equal speed along a preset direction by rotating the feeding mechanism 200 relative to the base 100. In some of the specific embodiments, the upper end surface of the base 100 is a plane, and the upper end surface of the base 100 is used to place the battery cell 500 to be disassembled. The cutter 300 is a rectangular sheet, and the blade of the cutter 300 is parallel to the upper end surface of the base 100, thereby ensuring that during the movement of the cutter 300, the side of the battery cell 500 to be disassembled close to the cutter 300 always remains parallel to the cutter 300. The relative position of the cutter 300 and the battery cell 500 to be disassembled is controlled by the feeding mechanism 200, and after the cutter 300 contacts the battery cell 500 to be disassembled, it continues to move a moving distance to achieve cutting of the outer shell of the battery cell 500 to be disassembled. In some specific embodiments, the preset direction is the vector sum of a first direction perpendicular to the base 100 and a second direction parallel to the base 100. The feed mechanism 200 is rotated relative to the base 100 so that the tool 300 always moves along the preset direction, so that the displacement of the tool 300 along the first direction perpendicular to the base 100 is used to cut the battery cell 500 to be disassembled along the thickness direction, and the displacement of the tool 300 along the first direction parallel to the base 100 is used to cut the battery cell 500 to be disassembled along the length or width direction, which is conducive to quickly cutting the outer shell of the battery cell 500 to be disassembled to complete the disassembly work.

[0041] By utilizing the technical solution of the above-mentioned embodiment of the present application, by setting a feeding mechanism 200 and a tool 300, any part of the tool 300 can approach or move away from the base 100 at an equal speed along a preset direction by rotating the feeding mechanism 200 relative to the base 100, thereby ensuring that the moving speed and moving direction of any part of the tool 300 are consistent, so that in the process of the tool 300 cutting the battery cell shell, the relative displacement of any part of the tool 300 and the battery cell shell is always consistent, thereby ensuring the consistency of the cutting depth. Compared with manual marking and cutting of the battery cell, the battery cell disassembly tool can keep the cutting depth of the battery cell shell consistent, thereby avoiding inconsistent marking depth caused by uneven force, causing scratches on the internal battery cell insulation film and avoiding safety accidents.

[0042] Reference Figure 4 As shown, in some embodiments provided in the present application, the feeding mechanism 200 includes a first link 210, a second link 220 and a third link 230, the first link 210 has a first end and a second end, the first end is rotatably connected to the base 100; the second link 220 has a third end and a fourth end, the third end is rotatably connected to the base 100, and the length of the second link 220 is equal to the length of the first link 210; the third link 230 is located above the base 100, one end of the third link 230 is rotatably connected to the second end, and the other end is rotatably connected to the fourth end, and the length of the third link 230 is equal to the distance between the first end and the third end; the tool 300 is connected to the third link 230, and the first link 210 and the second link 220 rotate relative to the base 100 so that the third link 230 drives the tool 300 to approach or move away from the base 100 along a preset direction. In some specific embodiments, the first end and the base 100, the third end and the base 100, the second end and the second connecting rod 220, and the fourth end and the second connecting rod 220 are all rotatably connected via a pin. In this way, the base 100, the first connecting rod 210, the second connecting rod 220 and the third connecting rod 230 form a parallelogram transmission structure. During the movement of the third connecting rod 230, the third connecting rod 230 always remains parallel to the base 100. By connecting the cutter 300 to the third connecting rod 230, it is ensured that the cutter 300 always remains parallel to the base 100 during the movement, so that when the cutter 300 cuts the battery cell shell, any part of the cutter 300 has the same cutting depth on the battery cell 500 to be disassembled.

[0043] Reference Figure 2As shown, in some embodiments provided by the present application, the first connecting rod 210 and the second connecting rod 220 are arranged crosswise, and the middle part of the first connecting rod 210 is rotatably connected to the middle part of the second connecting rod 220; the second end / fourth end can slide along the length direction of the third connecting rod 230, and correspondingly, the third end / first end can slide along the length direction of the third connecting rod 230 relative to the base 100. In some specific embodiments, the middle part of the first connecting rod 210 is rotatably connected to the middle part of the second connecting rod 220 through a pin; the third connecting rod 230 is provided with a first long hole 231, the length direction of the first long hole 231 is parallel to the length direction of the third connecting rod 230, and the second end is slidably connected to the inner wall of the first long hole 231 through a pin; the base 100 is provided with a sliding seat 240, and the sliding seat 240 is provided with a second long hole 241, the length direction of the second long hole 241 is parallel to the length direction of the third connecting rod 230, and the third end is slidably connected to the inner wall of the second long hole 241 through a pin. In this way, by making the first connecting rod 210 and the second connecting rod 220 cross-rotatably connected, and making the ends of the first connecting rod 210 and the second connecting rod 220 away from the battery cell 500 to be disassembled slide along the length direction of the third connecting rod 230, the displacement of the third connecting rod 230 in the left-right direction during the movement process can be reduced, thereby reducing the displacement of the tool 300 in the left-right direction during the movement process, which is conducive to reducing the length of the tool 300 and the length of the entire tool. It can also reduce the length of the tool 300 without affecting the cutting of the battery cell 500 to be disassembled. In addition, by making the first connecting rod 210 and the second connecting rod 220 cross-rotatably connected, the stability of the tool can also be enhanced.

[0044] Reference Figure 2 As shown, in some embodiments provided by the present application, the length direction of the cutter 300 is parallel to the length direction of the third connecting rod 230. In some specific embodiments, the cutter 300 and the third connecting rod 230 can be set as an integral structure, so that the cutter 300 can be ensured to always remain parallel to the base 100 during the movement of the cutter 300, so that when the cutter 300 cuts the battery cell shell, any part of the cutter 300 has the same cutting depth on the battery cell 500 to be disassembled.

[0045] Reference Figure 2As shown, in some embodiments provided by the present application, the battery cell disassembly tool further includes a force rod 250, which is connected to the second connecting rod 220, and the length direction of the force rod 250 is parallel to the length direction of the second connecting rod 220. Specifically, the force rod 250 is located at one end of the second connecting rod 220 close to the tool 300, that is, the force rod 250 is located above the tool 300, and the force rod 250 and the tool 300 have an angle, so that in the process of pressing the force rod 250, the force rod 250 can generate a horizontal component force to the left and a vertical component force downward, thereby smoothly driving the third connecting rod 230 and the tool 300 to move leftward and downward. In some specific embodiments, the force rod 250 and the second connecting rod 220 are an integrated structure, thereby enhancing the structural strength of the force rod 250 and the second connecting rod 220.

[0046] Reference Figure 2 As shown, in some embodiments provided by the present application, the cutter 300 includes a cutter housing 310 and a cutter body 320, and a limited position plane is formed on the cutter housing 310; the cutter body 320 is mounted on the cutter housing 310, and a blade is formed on the portion of the cutter body 320 protruding from the limited position plane. By setting the limited position plane, during the cutting process, when the limited position plane contacts the battery cell 500 to be disassembled, the limited position plane will be blocked by the outer shell of the battery cell 500 to be disassembled, thereby preventing the blade from excessively penetrating into the battery cell 500 to be disassembled, so that the cutting depth of the battery cell 500 to be disassembled remains consistent.

[0047] Reference Figure 5 As shown, in some embodiments provided in the present application, the battery cell disassembly tool further includes a base 400 and a limiting portion, wherein the base 400 is disposed on the base 100; the limiting portion is disposed on the base 400, and the limiting portion is used to limit the battery cell 500 to be disassembled. In some specific embodiments, the base 400 is detachably connected to the base 100, for example, by bolts, so that the base 400 can be easily replaced to adapt to different models of battery cells 500 to be disassembled. In other specific embodiments, the limiting portion includes a first limiting portion 410 and a second limiting portion 420. Specifically, the upper end surface of the base 400 is a plane, the first limiting portion 410 and the second limiting portion 420 are limiting blocks protruding from the base 400, the inner side surface of the first limiting portion 410 and the inner side surface of the second limiting portion 420 are perpendicular to each other, the inner side surface of the first limiting portion 410 is used to abut against the side surface of the battery cell 500 to be disassembled, and the inner side surface of the second limiting portion 420 is used to abut against the end surface of the battery cell 500 to be disassembled, thereby limiting the degree of freedom of the battery cell 500 to be disassembled.

[0048] The working process of the battery cell disassembly tooling of the embodiment of the present application is as follows:

[0049] During disassembly, the battery cell 500 to be disassembled is placed on the base 400, the first limiting portion 410 abuts against the side surface of the battery cell 500 to be disassembled, and the second limiting portion 420 abuts against the end surface of the battery cell 500 to be disassembled, so as to constrain the battery cell 500 to be disassembled on the base 400;

[0050] The force-applying rod 250 is pressed downward, and the force-applying rod 250 drives the cutter 300 to move downward, and the cutter 300 cuts downward the outer shell of the battery cell 500 to be disassembled; after the cutter 300 cuts the outer shell of the battery cell 500 to be disassembled to a certain depth (when the limiting plane contacts the battery cell 500 to be disassembled), the cutter 300 stops feeding;

[0051] After one side of the shell of the battery cell 500 to be disassembled is cut, the force applying rod 250 is lifted, the battery cell 500 to be disassembled is moved, and the other side of the shell of the battery cell 500 to be disassembled is cut. After the four sides of the shell of the battery cell 500 to be disassembled are all separated from the end cover plate, the battery cell 500 to be disassembled is completely disassembled.
