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 casing. This disassembly process usually requires professional disassembly personnel to operate, and disassembly accidents often occur. At the very least, it may cause a short circuit in the battery cell and a fire. At worst, it may cause injuries to the disassembly personnel or even a fire in the disassembly room.

[0003] Currently, battery cell shells are usually disassembled by professional disassemblers using a ceramic knife to manually draw a circle along the bottom of the battery 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 body may easily break due to uneven force, and bounce to nearby people, posing a safety hazard; disassemblers need to receive professional training before they can use diagonal pliers to break the shell along the line. This operation step is not easy for personnel to quickly get started and requires a certain amount of personnel training costs. Utility Model Content

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions of this application in conjunction with the embodiments. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0035] The following combination Figure 1-Figure 4 , describing the battery cell disassembly tooling provided in the embodiments of the present application.

[0036] Reference Figure 1 As shown, in some embodiments provided in the present application, the battery cell disassembly tooling includes a base 100, a moving component 200 and a cutting component 300. The moving component 200 is arranged on the base 100 and is used to carry the battery cell 400 to be disassembled. The moving component 200 can drive the battery cell 400 to be disassembled to move along a preset direction; the cutting component 300 is arranged on the base 100. The cutting component 300 can maintain contact with the side of the battery cell 400 to be disassembled away from the base 100 during the movement of the moving component 200 and cut the side of the battery cell 400 to be disassembled away from the base 100. In some specific embodiments, the moving assembly 200 includes a slide 210, a guide block, and a guide rail 220. The upper end surface of the slide 210 is formed with a flat surface for carrying the battery cell 400 to be disassembled; the guide block is provided on the lower end surface of the slide 210, and the guide rail 220 is mounted on the base 100. The length direction of the guide rail 220 is the same as the length direction of the base 100. The guide block matches the guide rail 220. By pushing the slide 210 by hand, the guide block can be moved along the guide rail 220, thereby moving the battery cell 400 to be disassembled on the slide 210 along the length direction of the base 100. In other embodiments, a driving member is further included, which can be a motor, a hydraulic cylinder, or a pneumatic cylinder. Driven by the driving member, the slide 210 drives the battery cell 400 to be disassembled to move along the length direction of the base 100. In some specific embodiments, the cutting assembly 300 can move along the height direction of the base 100. Before disassembling the battery cell 400 to be disassembled, the cutting depth of the cutting assembly 300 is first determined based on the size of the battery cell 400 to be disassembled and the thickness of the shell, and then the cutting assembly 300 is adjusted to an appropriate height so that the cutting assembly 300 cuts the side of the battery cell 400 to be disassembled away from the base 100.

[0037] By utilizing the technical solution of the above-mentioned embodiment of the present application, by providing the moving assembly 200 and the cutting assembly 300, during the process of cutting the battery cell 400 to be disassembled, the position of the cutting assembly 300 is kept stationary, and the battery cell 400 to be disassembled is moved along the length direction of the base 100, so that the cutting depth of the cutting assembly 300 can be kept constant, thereby ensuring the consistency of the cutting depth and avoiding the inconsistent depth of the marking caused by uneven force. In addition, by keeping the cutting assembly 300 stationary and allowing the moving assembly 200 to drive the battery cell 400 to be disassembled to move and achieve the cutting of the battery cell 400 to be disassembled, it is possible to prevent the cutter from injuring people and avoid causing safety accidents.

[0038] Reference Figure 2 As shown, in some embodiments provided in the present application, the cutting assembly 300 includes a pressing handle 310, a fixing member 320 and a cutter 330, one end of the pressing handle 310 is rotatably connected to the base 100; the fixing member 320 is arranged on the base 100, and the fixing member 320 is connected to the pressing handle 310 so that the angle between the pressing handle 310 and the base 100 remains unchanged; the cutter 330 is installed at the other end of the pressing handle 310, and is used to cut the side of the battery cell 400 to be disassembled away from the base 100. Specifically, a pin seat is protruding from the base 100, and one end of the pressing handle 310 is rotatably connected to the pin seat by a pin shaft, so that the pressing handle 310 can be rotated on the base 100; in some specific embodiments, a fixing bolt 340 is also included, and a first long hole 311 is provided on the pressing handle 310, and the length direction of the first long hole 311 is the same as the length direction of the pressing handle 310, and a second long hole 323 is provided on the fixing member 320. After the pressing handle 310 is rotated to a suitable position around the pin shaft, the fixing bolt 340 is passed through the first long hole 311 and the second long hole 323, so that the pressing handle 310 and the fixing member 320 are connected by the fixing bolt 340, so that the angle between the pressing handle 310 and the base 100 remains unchanged, thereby fixing the tool 330 on the pressing handle 310 in the cutting position.

[0039] Reference Figure 2 As shown, in some embodiments provided herein, the pressing handle 310 is a curved rod, with the middle portion of the pressing handle 310 bent away from the base 100 to form the curved rod. By bending the middle portion of the pressing handle 310 away from the base 100 to form the curved rod, the curved rod can exert downward pressure on the cutting tool 330 during the process of cutting the battery cell 400 to be disassembled, which helps the cutting tool 330 to smoothly cut the battery cell 400 to be disassembled. In addition, the curved structure helps to enhance the stability of the pressing handle 310 itself and prevent the cutting tool 330 from vibrating up and down.

[0040] Reference Figure 1 、 Figure 3As shown, in some embodiments provided herein, the fixing member 320 includes a first upright pole 321 and a second upright pole 322. A gap is defined between the first upright pole 321 and the second upright pole 322. The pressing handle 310 is disposed in the gap, and opposite sides of the pressing handle 310 are respectively slidably connected to the first upright pole 321 and the second upright pole 322. By passing the pressing handle 310 through the gap between the first upright pole 321 and the second upright pole 322, and the opposite sides of the pressing handle 310 are respectively slidably connected to the first upright pole 321 and the second upright pole 322, it is helpful to prevent the pressing handle 310 from vibrating back and forth, thereby ensuring that the cutter 330 can stably cut the battery cell 400 to be disassembled.

[0041] Reference Figure 4 As shown, in some embodiments provided in the present application, the cutter 330 has a first blade 331 and a second blade 332, and the first blade 331 and the second blade 332 are arranged opposite to each other in the length direction of the fixing member. In some specific embodiments, the cutter 330 is in the shape of an inverted triangle, and the first blade 331 and the second blade 332 are respectively the two sides of the inverted triangle. Specifically, the first blade 331 faces the left side, and the second blade 332 faces the right side, and the first blade 331 and the second blade 332 are connected in a smooth transition. In this way, when the slide 210 moves to the right, the second blade 332 can cut the outer shell of the battery cell 400 to be disassembled; when the slide 210 moves to the left, the first blade 331 can cut the outer shell of the battery cell 400 to be disassembled.

[0042] In some embodiments provided herein, a limiting portion is provided on the slide 210, and the limiting portion is used to limit the battery cell 400 to be disassembled. In some specific embodiments, the limiting portion includes a first limiting block 230 and a second limiting block 240, wherein the first limiting block 230 is provided on the front or rear side of the slide 210, and the first limiting block 230 is used to abut against the side surface of the battery cell 400 to be disassembled, and there are two second limiting blocks 240, which are respectively provided on the left and right sides of the slide 210, and the two second limiting blocks 240 are respectively used to abut against the two end surfaces of the battery cell 400 to be disassembled, thereby preventing the battery cell 400 from shifting during the movement and cutting process.

[0043] The use process of the battery cell disassembly tool provided in the embodiment of the present application is as follows:

[0044] The handheld pressing handle 310 is rotated around the pin axis to adjust the feed depth of the tool 330 to match the thickness of the battery cell shell;

[0045] Install the fixing bolt 340 to connect the middle of the pressing handle 310 to the first vertical rod 321 and the second vertical rod 322 on the base 100 to fix the feed depth of the tool 330;

[0046] The battery cell 400 to be disassembled is placed on the slide 210. The disassembler pushes the slide 210 to make the battery cell 400 to be disassembled approach the tool 330. After the tool 330 contacts the upper end surface of the battery cell 400 to be disassembled, the slide 210 is continued to be pushed, and the tool 330 cuts the outer shell of the battery cell 400 to be disassembled. After completing the cutting of the upper end surface, the battery cell 400 to be disassembled is turned over, and the four sides of the battery cell 400 to be disassembled are cut in turn.
