Description

Technical Field

[0001] The utility model relates to the technical field of battery pack disassembly, in particular to a battery pack disassembly workstation. Background Art

[0002] Battery packs are an important part of new energy vehicles. With the development of production technology and the passage of time, there will be a large number of retired battery packs that need to be recycled and reused. From the materials made of battery packs, it can be seen that the battery packs contain some scarce materials. In order to recycle and reuse these materials, the battery packs need to be disassembled.

[0003] In fact, a battery pack generally includes a shell, multiple groups of battery modules fixed in the shell, and a cooling plate fixed on the lower side of the shell. In addition, a fastening filler is often used in the internal structure of the battery pack to fasten the battery module, and the fastening filler also plays a role in heat conduction. At present, in order to remove the battery module, the cooling plate needs to be removed. Before removing the cooling plate, the fastening filler must also be removed. Since this type of structural battery pack currently uses high or low temperatures or adds chemical agents to make the fastening filler ineffective before disassembly, the disassembly efficiency is low.

[0036] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, so as to more clearly understand the technical ideas claimed for protection by the present invention. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0037] It should be noted that when the battery pack is produced and assembled, the battery module is first placed in the shell and fastened by threaded connection. After fastening, the shell is turned over and the cooling plate and fastening filling glue are installed. Therefore, when the battery pack is disassembled by the traditional disassembly method, the fastening filling glue must be disabled first, and then the cooling plate is removed, and the battery module is turned over and removed after being threadedly connected to the shell.

[0038] like Figure 1 As shown, a battery pack disassembly workstation in an embodiment of the utility model includes a cutting workbench 100, a cutting device 200, a rolling and folding workbench 300, a rolling and folding device 400 and a moving device 500.

[0039] The cutting workbench 100 is used to place the battery pack to be cut; in fact, the cutting workbench 100 can be a processing table, and the battery pack to be cut is inverted on the cutting workbench 100, and at this time, the cooling plate is located on the upper side of the battery pack.

[0040] The cutting device 200 is arranged next to the cutting workbench 100 and is used to cut the cooling plate of the battery pack on the workbench; in fact, the cutting device 200 can be a cutting robot arm or include a moving device and a cutting machine installed on the moving device, which can cut the cooling plate into multiple pieces, so that the folding device 400 can fold and peel off the multiple cooling plates.

At this time, the cooling plate cut into multiple pieces is located on the upper side of the battery pack.

[0042] The folding device 400 is arranged beside the folding workbench 300 and is used to roll and peel off the cooling pack of the battery pack on the folding workbench 300; in fact, the folding device 400 can be a folding robot arm or include a follow-up device and a rotating shaft installed on the follow-up device. The cooling plate is wound on the folding device 400, and the folding device 400 drives the cooling plate to be wound into multiple circles. During the folding process of the cooling plate, it is separated from the fastening filling glue adhered to the folding plate, and there is no need to perform an invalidation treatment on the fastening filling glue, thereby improving the disassembly efficiency. It should be noted that it generally takes more than 48 hours to perform an invalidation treatment on the fastening filling glue, while cutting and folding can be controlled within tens of minutes or even less than 10 minutes, thereby improving the disassembly efficiency.

[0043] The accompanying device 500 is used to drive the battery pack to switch positions between the cutting workbench 100 and the folding workbench 300; in fact, the accompanying device 500 can include a accompanying device and a clamping device installed on the accompanying device, which can drive the battery pack to move, so that the battery pack can be placed on the cutting workbench 100 and the folding workbench 300 in turn.

[0044] A battery pack disassembly workstation of the utility model cooperates with a cutting workbench 100, a cutting device 200, a folding workbench 300, a folding device 400 and a moving device 500 to first cut and then fold and peel off the cooling plate of the battery pack, without the need to deal with the failure of the fastening filling glue, thereby improving the disassembly efficiency.

[0045] Specifically, Figure 2 and Figure 3 As shown, the cutting workbench 100 and the folding workbench 300 preferably include a lifting platform 110, a clamping platform 120 fixed on the upper side of the lifting platform 110, and a clamping device 130 installed on the clamping platform 120 for clamping the left and right sides of the battery pack. In fact, the lifting platform 110 can be a hydraulic scissor lift, and the clamping device 130 can be a clamping cylinder with a clamping block. The clamping device 130 cooperates with the clamping platform 120 to prevent the battery pack from shaking and shifting during the cutting or folding process, ensuring smooth processing. The lifting platform 110 can drive the battery pack to move up and down to change its position, so as to load and unload the battery pack and adjust the corresponding processing height.

[0046] Furthermore, the clamping device 130 preferably includes two clamping arms 131 that are relatively arranged left and right and connected to the clamping platform 120 for sliding left and right, a screw rod 132 that is rotatably connected to the clamping platform 120, and a screw rod 132 for driving the two clamping arms 131 to open and close, and a first driving mechanism 133 for driving the screw rod 132 to rotate; in fact, the screw rod 132 is extended left and right, and can be two threaded segments with opposite rotation directions and the same lead, and each clamping arm 131 is correspondingly threadedly connected to the two threaded segments, and the first driving mechanism 133 can be a servo motor, so as to realize driving the two clamping arms 131 to open and close, so as to clamp and fix the battery pack. Furthermore, as Figure 4 As shown, the clamping device 130 also preferably includes two insulating plates 134 which are fixed one-to-one on the inner side of the clamping arm 131 and are used to contact the battery pack. At the same time, the surface of the clamping table 120 supporting the battery pack is also made of insulating material to prevent the battery pack from leaking electricity during processing and affecting the operation of the clamping device.

[0047] Specifically, Figure 5 As shown, the cutting device 200 preferably includes a first XYZ three-axis moving table 210 and a circular saw cutting machine 220 installed at the output end of the first XYZ three-axis moving table 210. The first XYZ three-axis moving table 210 can drive the circular saw cutting machine 220 to move along a preset path and cut the cooling plate of the battery pack into multiple pieces.

[0048] Specifically, Figure 6 and Figure 7 As shown, the folding device 400 preferably includes a second XYZ three-axis moving platform 410, a folding frame 420 installed at the output end of the second XYZ three-axis moving platform 410, a folding roller 430 rotatably connected to the folding frame 420, and a second driving mechanism 440 installed on the folding frame 420 for driving the folding roller 430 to rotate. The folding roller 430 is provided with a folding groove 450 for the cooling plate to extend into on the side. The second driving mechanism 440 can be a servo motor, which can drive the folding roller 430 to rotate at a set speed. The raised part of the cooling pack is inserted into the folding groove 450, and the second driving mechanism 440 drives the folding roller 430 to rotate. At the same time, the second XYZ three-axis moving platform 410 drives the folding roller 430 on the folding frame 420 to translate, so that the folding roller 430 translates and rotates at the same time, so that the cooling plate is folded into multiple circles and separated from the battery pack shell and the fastening filling glue.

[0049] Specifically, Figure 1 As shown, the accompanying device 500 preferably includes a third XYZ three-axis moving platform 510 and a lifting device 520 installed at the output end of the third XYZ three-axis moving platform 510, and the lifting device 520 is used to lift the battery pack to drive the battery to move and switch to a desired position.

[0050] It is worth mentioning that a loading and unloading area for loading and unloading the battery pack is preferably reserved between the cutting workbench 100 and the folding workbench 300; the battery pack can be moved to the loading and unloading area by a forklift or a material transfer vehicle, and the sling 520 can be hooked on the battery pack in the loading and unloading area to realize the loading of the battery pack. After the battery pack is folded, it is moved to the loading and unloading area and can be removed by a forklift or a material transfer vehicle, thereby reducing the impact of the loading and unloading process on cutting or folding.

[0051] Further, such as Figure 8 As shown, the hoist 520 preferably includes a hanger 521 installed at the output end of the third XYZ three-axis mobile platform 510, a plurality of ropes 522 with upper ends installed on the hanger 521, and a plurality of hooks 523 installed one-to-one at the lower ends of the lower ropes 522. When hoisting the battery pack, the hooks 523 can be used to hook the multiple rings of the battery pack, thereby reducing the probability of the battery pack falling and improving the safety of the battery pack hoisting.

[0052] Furthermore, Fig. 9 As shown, the hanger 521 is preferably provided with a plurality of T-slots 524 with openings facing outward and the lower ends extending through the lower side of the hanger 521. The hanger 520 also preferably includes a plurality of T-bolts 525 for being placed in the T-slots 524 and a plurality of connecting sleeves 526 whose lower ends are connected to the upper ends of the plurality of hanging ropes 522 in a one-to-one corresponding manner. The connecting sleeves 526 are used for threaded connection of the portion of the T-bolts 525 extending from the lower ends of the T-slots 524. The upper ends of the hanging ropes 522 can be detachably mounted on the hanger 521 through the cooperation of the T-slots 524, the T-bolts 525 and the connecting sleeves 526. The upper ends of the hanging ropes 522 can also be installed in T-slots 524 at different positions, so that the position of the hanging ropes 522 can be changed, thereby being able to adapt to different models of battery packs within a certain range.
