Description

Technical Field

[0001] This utility model relates to the field of battery recycling equipment technology, specifically to a battery pack disassembly device. Background Technology

[0002] A battery pack includes battery modules and a housing that contains them. After prolonged use, the lifespan of the battery modules gradually decreases, eventually rendering them unable to power electrical equipment properly. Therefore, replacement or maintenance is necessary, and the battery modules can be recycled.

[0003] When battery modules need repair or recycling, the battery pack needs to be disassembled, especially the battery pack casing. Existing technologies include using a screwdriver to unscrew the screws on the casing and remove it completely, and using tools such as pry bars, hammers, and chisels to manually disassemble the battery pack casing. However, the disassembly efficiency is very low, and using tools like pry bars, hammers, and chisels may damage the battery modules inside the casing. There are also methods using a cutter to cut the casing for battery module recycling (patent applications 202411123549.X and 202311669878.X), but these devices can only cut one side of the battery pack casing. Cutting the other sides requires additional structures or manual adjustments, further affecting disassembly efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a battery pack disassembly device that can quickly adjust the orientation of the battery pack, thereby improving disassembly efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0008] Preferably, there are two or more limiting strips arranged in parallel, and the adjusting rods on the limiting strips all pass through the support plate and are fixed to the adjusting plate.

[0009] Preferably, the cutting mechanism is disposed between two adjacent limiting strips and is arranged parallel to the limiting strips.

[0017] This invention improves disassembly efficiency by configuring the base plate as a rotating plate and a sliding plate, connected by a shaft and bearings, enabling rapid reversal of the battery pack. Combined with a cutting wheel driven by a second motor, this allows for rapid cutting. Simultaneously, adjustment and fixing mechanisms are located on both sides of the battery pack, with a cutting mechanism on the same side as the adjustment mechanism, allowing for adjustment and fixation of the cutting depth. The adjustment mechanism adjusts the cutting depth by varying the distance between the limiting strip on the adjustment mechanism and the cutting wheel on the cutting mechanism, enabling the cutting of battery packs of different thicknesses. When disassembling battery packs from the same batch or of the same thickness, no adjustment of the cutting depth is required, further increasing the overall disassembly efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Unless otherwise specified, the technical means used in the implementation examples are conventional means well known to those skilled in the art.

[0024] refer to Figures 1-3This utility model discloses a battery pack disassembly device, which is mainly used to cut the outer shell or box of the battery pack. The disassembly device includes a horizontally placed base plate 1, with a support foot at the bottom of the base plate. A bottom plate is slidably disposed on the base plate 1. At least two parallel second slide rails 24 are disposed on the base plate 1. A second slider 25 is disposed on the second slide rail 24. The second slider 25 is fixed to the bottom surface of the bottom plate, so that the bottom plate can move along the second slide rails to move the battery panel on the bottom plate out of the cutting area.

[0025] Furthermore, a battery pack 2 is placed on the base plate. A support plate 3 and an upright plate 4 are respectively provided on the base plate 1 on both sides of the base plate. The upright plate 4 is arranged parallel to the support plate 3 and also parallel to the second slide rail. A battery pack adjustment mechanism and a cutting mechanism are provided on the support plate 3. A battery pack fixing mechanism is provided on the upright plate 4. The base plate includes a rotating plate 5 and a sliding plate 6 of the same shape and size. A rotating shaft 7 is provided at the bottom center of the rotating plate 5. The rotating shaft 7 is inserted into the center of the sliding plate 6 and fixed by a bearing 8. That is, the bearing is embedded in the sliding plate and the rotating shaft is fixed by the bearing, so that the rotating plate rotates under the action of the bearing. The sliding plate is fixed to the second slider. After one side of the box is cut, the fixing of the battery pack is released. The battery pack is moved out of the area where the support plate and the upright plate are located by moving the bottom plate along the second slide rail. Then, the battery pack is rotated directly. Under the action of the rotating plate, the direction of the battery pack is adjusted so that the uncut side is aligned with the cutting mechanism. The battery pack is pushed into the area of ​​the upright plate and the support plate. The battery pack is then fixed, and the cutting mechanism is turned on to cut the box. The same operation is performed on the other two sides.

[0026] Furthermore, the adjustment mechanism includes a horizontally arranged limiting strip 9, with adjusting rods 10 vertically arranged near its two ends. The adjusting rods 10 pass through the support plate 3 and are connected to an adjusting plate 11. An adjusting bolt 12 is threaded through the center of the adjusting plate 11 and is threadedly connected to the adjusting plate 11. One end of the adjusting bolt 12, passing through the adjusting plate 11, is rotatably connected to the support plate 3, allowing for rotatable connection via a bearing. One end of the adjusting bolt is inserted into the inner ring of the bearing, which can be directly embedded and fixed within the support plate. It should be noted that the adjusting rod and the support plate have a clearance fit, allowing the adjusting rod to slide back and forth under the action of the adjusting bolt. By tightening the adjusting bolt, with the adjusting bolt threadedly connected to the adjusting plate, the adjusting plate moves towards the support plate, thereby causing the limiting strip to move towards the battery pack until it contacts the battery pack. The position where the limiting strip contacts the battery pack, i.e., the length of the adjusting rod passing through the support plate, determines the cutting depth of the cutting mechanism, enabling the cutting of casings of different thicknesses.

[0027] Furthermore, to ensure the stability of the battery pack when supported by the limiting strips, two or more limiting strips 9 are provided and arranged in parallel. The adjusting rods 10 on each limiting strip 9 pass through the support plate 3 and are fixed to the adjusting plate 11. It should be noted that, as a preferred embodiment, there are two limiting strips, positioned near the top and bottom surfaces of the battery pack, while the cutting mechanism is positioned between the two limiting strips 9, parallel to them. When the casing is cut, the limiting strips abut against the top and bottom sides of the casing, better ensuring its stability and preventing deformation due to uneven force when supporting the casing after cutting, which could lead to changes in the sides of the casing and issues such as cutting too shallow or too deep during the cutting process.

[0028] Furthermore, the cutting mechanism includes a first slide rail 13 horizontally arranged on the support plate 3, the first slide rail and the second slide rail being parallel to each other. A first slider 14 is adapted on the first slide rail 13. Support seats 15 are provided at both ends of the first slide rail 13. A lead screw 16 is provided on the support seat 15, the lead screw being parallel to the first slide rail. A first motor 17 is provided at one end of the lead screw 16, and the first motor is fixed on the support seat. The support seat can be understood as a bearing seat. A lead screw nut 18 is provided on the lead screw 16, and the lead screw nut 18 is connected to the first slider 14. When the first motor drives the lead screw to rotate, the lead screw nut, along with the first slider, reciprocates along the first slide rail and the lead screw. The lead screw nut 18 is equipped with a second motor 19, and the output end of the second motor 19 is equipped with a cutting wheel 20. When the second motor drives the cutting wheel to rotate, under the action of the first lead screw and the first slide rail, the second motor moves the cutting wheel along the side of the housing, thereby cutting the battery pack 2 in the horizontal direction. After the cutting is completed, the first lead screw drives the second motor to reset. After rotating the direction of the battery pack, the cutting of the other side is performed.

[0029] Furthermore, the fixing mechanism includes a fixing plate 21 parallel to the upright plate 4 and facing the battery pack 2. A telescopic member 22 is provided on the upright plate 4. The output rod of the telescopic member 22 passes through the upright plate 4 and connects to the center of the fixing plate 21. A clearance fit is maintained between the output rod and the upright plate to avoid affecting the use of the telescopic member. The telescopic member includes, but is not limited to, electric push rods and hydraulic push rods. In use, the telescopic member moves the fixing plate towards the battery pack until it is pressed against the battery pack. Combined with the limiting strip, the battery pack is fixed, thereby allowing for stable cutting of the battery pack casing.

[0030] Furthermore, when the area of ​​the fixing plate is large, in order to ensure its stability and avoid deformation at the connection between the fixing plate and the output rod, guide rods 23 are provided near the four corners of the fixing plate 21. The guide rods 23 are provided through the upright plate 4 and are fitted with the upright plate with a gap. When the telescopic rod pushes the fixing plate to move, the guide rods at the four corners play a positioning and guiding role, so that the force applied by the fixing plate to the battery pack is more uniform.

[0031] Furthermore, to prevent the second slider from detaching from the second slide rail, baffles 26 are respectively provided on the base plate 1 at both ends of the second slide rail 24, and the baffles 26 are perpendicular to the second slide rail 24. As one embodiment, the baffles can be disposed between the two second slide rails and are perpendicular to the second slide rails.

[0032] Furthermore, in order to move the battery pack out of the cutting area and enable the battery pack to complete the reversal, the length of the second slide rail 24 is greater than or equal to twice the width of the base plate along the second slide rail 24.

[0033] When using this invention, first determine the cutting depth based on the thickness of the battery pack casing. Then, adjust the cutting depth by adjusting the distance difference between the limiting strip and the cutting wheel facing the battery pack side using adjusting bolts. A smaller distance results in a shallower cutting depth, and a larger distance results in a deeper cutting depth. After adjusting the cutting depth, the limiting strip is no longer adjusted. Place the battery pack on the rotating plate, push it into the area between the upright plate and the support plate, and ensure that one side of the battery pack is in full contact with the limiting strip. Then, activate the telescopic component to press the fixing plate against the other side of the battery pack. Finally, start the second motor. By controlling the speed of the second motor and the speed of the first motor, the cutting intensity and linear speed are controlled. After one side of the battery pack is cut, the cutting wheel returns to its original position, the telescopic component releases its fixation on the battery pack, and the battery pack is moved out of the cutting area (the area between the support plate and the upright plate) by the action of the second slide rail. Rotate the battery pack so that the uncut side faces the limiting strip. Repeat the above operation until all four sides of the battery pack are cut. Then, place a new battery pack for the next round of cutting. If the battery packs are from the same batch or the casing thickness is consistent, there is no need to adjust the limit strip.
