Description

Technical Field

[0001] The present disclosure relates to the technical field of recycling of automotive power batteries, and particularly to a CTP battery pack shell tearing device. Background Art

[0002] In a CTP battery pack (Cell to Pack, blade battery), in order to prevent the cell modules from being damaged when subjected to external forces such as bumps, a two-component adhesive is usually laid on the bottom shell of the CTP battery pack. The cell modules can be firmly installed on the bottom shell through the adhesive, so as to resist external forces such as bumps. Thus, after the CTP battery pack is retired, it is generally difficult to directly take out the cell modules from the shell of the CTP battery pack for secondary use, and violent disassembly has to be carried out through processes such as disassembly by a disassembling machine and freezing and hammering. However, since the CTP battery pack is prone to damage to the shape of the cell modules and loss of electrical performance during violent disassembly, resulting in waste of resources, some manufacturers have made further research in the recycling of CTP battery packs.

[0003] For example, Chinese patent document CN220311984U discloses a CTP battery pack disassembly tool. A control disassembly component is arranged at the top end of the disassembly tool body. The control disassembly component includes a telescopic rod, a steering plate, a driving motor and a disassembling knife. The telescopic rod is connected to the top surface of the steering plate. The driving motor is installed on the bottom side of the steering plate. The disassembling knife is movably installed inside the steering plate. A fixed base is installed below the control disassembly component. The fixed base includes a control disc, a pressing block, a limiting block and a hydraulic rod. The pressing block is installed inside the periphery of the control disc. The limiting block is rotatably connected to the bottom surface of the control disc. Both ends of the hydraulic rod are connected to the bottom end of the pressing block.

[0004] However, the above design of the CTP battery pack disassembly tool has the following problems:

[0005] For the above CTP battery pack disassembly tool, although it can cut the CTP battery pack through the disassembling knife and disassemble the CTP battery pack orderly, due to the sharp edge of the disassembling knife, it is difficult to determine the placement position of the cell modules in the CTP battery pack shell, so that the disassembling knife is still likely to damage the cell modules during the cutting process, and thus it is still difficult to completely disassemble and take out the cell modules from the CTP battery pack for secondary use.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this disclosure pertains. The terms used in the description of this disclosure herein are for the purpose of describing specific embodiments only and are not intended to limit this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the related listed items.

[0033] To better understand the technical solutions and beneficial effects of this disclosure, the following further describes this disclosure in detail with reference to specific embodiments:

[0034] As Figure 1 shown in Figure 2 FIG. 1, a CTP battery pack shell tearing device 10 of an embodiment includes a machine table 100, a battery pack clamping mechanism 200, and a shell tearing mechanism 300; the battery pack clamping mechanism 200 is fixedly arranged on the machine table 100, and the battery pack clamping mechanism 200 is used for placing and clamping a CTP battery pack 20; the shell tearing mechanism 300 includes a mounting carriage 310 and a shell clamping assembly 320, the mounting carriage 310 is arranged across the upper part of the battery pack clamping mechanism 200, and both ends of the mounting carriage 310 are respectively slidably connected to the machine table 100; the shell clamping assembly 320 is installed on the mounting carriage 310, and the clamping end of the shell clamping assembly 320 faces the battery pack clamping mechanism 200, and the shell clamping assembly 320 is used for clamping and tearing the shell 2020 of the CTP battery pack 20.

[0035] It can be understood that in the CTP battery pack shell tearing device 10 of this embodiment, the CTP battery pack 20 to be shell torn is soaked in hot water at 60°C - 65°C for 10 - 15 minutes, and the glue bonded to the battery cell monomers 2010 and the shell 2020 has been softened. After the CTP battery pack 20 is placed above the battery pack clamping mechanism 200, since the mounting carriage 310 is arranged across the upper part of the battery pack clamping mechanism 200 and the clamping end of the shell clamping assembly 320 on the mounting carriage 310 faces the battery pack clamping mechanism 200, the shell 2020 of the CTP battery pack 20 can be clamped by the clamping end of the shell clamping assembly 320. Because both ends of the mounting carriage 310 are slidably connected to the machine table 100, and the battery pack clamping mechanism 200 is fixedly arranged on the machine table 100, the mounting carriage 310 can drive the shell clamping assembly 320 to slide relative to the battery pack clamping mechanism 200 synchronously, so that the shell 2020 of the CTP battery pack 20 can be clamped and torn by the shell clamping assembly 320, and finally the shell 2020 of the CTP battery pack 20 can be quickly peeled off.

[0036] It can be understood that compared with the disassembly tool for the CTP battery pack 20 of the prior art, the above-mentioned CTP battery pack shell tearing device 10 grips and tears the shell 2020 of the CTP battery pack 20 through the shell clamping assembly 320, so that the shell 2020 of the CTP battery pack 20 can be quickly peeled off to expose the battery cell monomers 2010 inside the CTP battery pack 20, and the battery cell monomers 2010 will not be damaged during the whole process, thus the integrity of the whole battery cell monomers 2010 can be maintained, and finally the battery cell monomers 2010 can be fully utilized in a stepped manner after recycling.

[0037] Combined with Figure 3 As shown, in one embodiment, the shell clamping assembly 320 includes a lower bottom plate 3210, an upper pressing plate 3220 and a telescopic driver 3230; the lower bottom plate 3210 is installed on the installation slide 310, and the telescopic driver 3230 is installed on the lower bottom plate 3210; the upper pressing plate 3220 is arranged on the telescopic rod of the telescopic driver 3230 and is arranged opposite to the lower bottom plate 3210 to form a gap 3250. It can be understood that by arranging the upper pressing plate 3220 on the telescopic rod of the telescopic driver 3230, the lower bottom plate 3210 and the upper pressing plate 3220 are arranged opposite to each other to form a gap 3250. When performing the shell tearing operation, the end of the shell 2020 of the CTP battery pack 20 can be inserted into the gap 3250, and the upper pressing plate 3220 is closed with the lower bottom plate 3210 under the drive of the telescopic driver 3230, so as to firmly grip the end of the shell 2020 of the CTP battery pack 20 for the shell tearing operation.

[0038] Figure 1 Compared with Figure 3 As shown, in this embodiment, the shell clamping assembly 320 further includes a plurality of guide slide rods 3211 arranged at intervals. One end of the guide slide rod 3211 is connected to the lower bottom plate 3210, and the other end of the guide slide rod 3211 passes through the upper pressing plate 3220 and is connected to the telescopic driver 3230. The guide slide rod 3211 is slidably connected to the upper pressing plate 3220. It can be understood that since the guide slide rod 3211 on the lower bottom plate 3210 is slidably connected to the upper pressing plate 3220, the upper pressing plate 3220 can more smoothly open and close the gap 3250 under the guiding action of the guide slide rod 3211 to grip the end of the shell 2020 of the CTP battery pack 20. At the same time, by connecting the ends of the guide slide rods 3211 to the telescopic driver 3230, the telescopic driver 3230 can be more firmly connected to the lower bottom plate 3210.

[0039] Combined with Figure 3As shown in the figure, further, the upper pressure plate 3220 is provided with an upper toothed plate 3221 in the gap 3250, and the lower bottom plate 3210 is provided with a lower toothed plate 3212. The upper toothed plate 3221 and the lower toothed plate 3212 are arranged opposite to each other. It can be understood that because the upper pressure plate 3220 is provided with an upper toothed plate 3221 in the gap 3250, and the lower toothed plate 3212 on the lower bottom plate 3210 is opposite to the upper toothed plate 3221 in position. When the upper pressure plate 3220 is driven by the telescopic driver 3230 to close with the lower bottom plate 3210, the end of the housing 2020 of the CTP battery pack 20 in the gap 3250 can be more firmly clamped by the lower toothed plate 3212 and the lower toothed plate 3212, so as to prevent the end of the housing 2020 of the CTP battery pack 20 from slipping out of the gap 3250. Specifically, the teeth of the lower toothed plate 3212 are arranged in a staggered manner with the teeth of the lower toothed plate 3212, that is, the teeth of the lower toothed plate 3212 can be engaged with the teeth of the lower toothed plate 3212, so as to further clamp the end of the housing 2020 of the CTP battery pack 20.

[0040] Combined with Figure 1 and Figure 3 As shown in the figure, in one embodiment, the lower bottom plate 3210 is rotatably connected to the mounting carriage 310. It can be understood that since the lower bottom plate 3210 is rotatably connected to the mounting carriage 310, the lower bottom plate 3210 can rotate relative to the mounting carriage 310, and then the clamping shell assembly 320 can be swung and adjusted to align with the CTP battery pack 20 placed on the battery pack clamping mechanism 200. Furthermore, the end of the housing 2020 of the CTP battery pack 20 can be flexibly adapted and clamped by the clamping shell assembly 320 to adapt to CTP battery packs of different models and different heights, expanding the use range of the CTP battery pack shell tearing device. Specifically, the lower bottom plate 3210 is rotatably connected to the mounting carriage 310 through a rotating shaft 3240. Of course, this is not limited here, and those skilled in the art can also achieve it in other ways.

[0041] Combined with Figure 2 As shown in the figure, in one embodiment, the number of the clamping shell assemblies 320 is multiple, and the multiple clamping shell assemblies 320 are arranged at intervals on the mounting carriage 310. Each clamping shell assembly 320 is used to clamp and tear one side of the housing 2020 of the CTP battery pack 20. It can be understood that by installing multiple clamping shell assemblies 320 on the mounting carriage 310 at the same time, since the multiple clamping shell assemblies 320 are arranged at intervals, each clamping shell assembly 320 can be used to clamp and tear one side of the housing 2020 of the CTP battery pack 20, so that all sides of the housing 2020 of the CTP battery pack 20 can be stressed and peeled off at one time, improving the efficiency of the shell tearing operation. Combined with Figure 1As shown, in this embodiment, the number of the split housing assemblies 320 is three. The top and both sides of the housing 2020 of the CTP battery pack 20 to be clamped and torn are respectively arranged opposite to one split housing assembly 320, so that the top and both sides of the housing 2020 of the CTP battery pack 20 to be clamped and torn are respectively clamped by the split housing assemblies 320 and stripped off at one time.

[0042] Combined with Figure 2 As shown, in one embodiment, the battery pack clamping mechanism 200 includes a placement plate 210, a limiting assembly 220 and an adjusting abutting assembly 230. The placement plate 210 is fixedly installed on the machine table 100. The limiting assembly 220 and the adjusting abutting assembly 230 are oppositely arranged on the placement plate 210 and form a battery pack clamping position 2110 with the placement plate 210. A mounting carriage 310 is arranged across and slidably above the battery pack clamping position 2110. It can be understood that since the limiting assembly 220 and the adjusting abutting assembly 230 are oppositely arranged on the placement plate 210, the limiting assembly 220, the adjusting abutting assembly 230 and the placement plate 210 can form the battery pack clamping position 2110, so that the CTP battery pack 20 can be clamped and fixed through the battery pack clamping position 2110. Also, because the mounting carriage 310 is arranged across and slidably above the battery pack clamping position 2110, the split housing assembly 320 on the mounting carriage 310 can clamp the housing 2020 of the CTP battery pack 20 and can slide along with the mounting carriage 310 to tear and strip off the housing 2020 of the CTP battery pack 20.

[0043] Combined with Figure 4 As shown, in this embodiment, the adjusting abutting assembly 230 includes a screw rod 2310, a support seat 2320 and an abutting plate 2330. The support seat 2320 is fixedly arranged on the placement plate 210. One end of the screw rod 2310 is in threaded fit with the screw hole 2321 of the support seat 2320, and the other end of the screw rod 2310 extends towards the battery pack clamping position 2110. A pushing portion 2311 is arranged at the end of the other end of the screw rod 2310. The abutting plate 2330 is arranged on the pushing portion 2311. It can be understood that since one end of the screw rod 2310 is in threaded fit with the screw hole 2321 of the support seat 2320, the other end of the screw rod 2310 extends towards the battery pack clamping position 2110, and the pushing portion 2311 is arranged at the end of the other end of the screw rod 2310, so that by turning the screw rod 2310, the pushing portion 2311 can be telescoped in the battery pack clamping position 2110. Also, because the abutting plate 2330 is arranged on the pushing portion 2311, the abutting plate 2330 can abut and fix the CTP battery pack 20 in the battery pack clamping position 2110 under the push of the pushing portion 2311, preventing the CTP battery pack 20 from moving during the shell tearing process, which may cause difficulties or failures in the shell tearing process.

[0044] Combined with Figure 4 And Figure 5As shown, further, a pressing buckle plate 2331 and a screw handle 2332 are provided on one side of the bottom plate 2330; the screw handle 2332 passes through the lifting adjustment hole 233a of the pressing buckle plate 2331 and is screwed to the bottom plate 2330; the pressing buckle plate 2331 extends a buckling portion 233b toward the battery pack clamping position 2110. It can be understood that since the screw handle 2332 passes through the lifting adjustment hole 233a of the pressing buckle plate 2331 and is screwed to the bottom plate 2330, the bottom plate 2330 and the pressing buckle plate 2331 can be pressed tightly by screwing the screw handle 2332. Also, because the pressing buckle plate 2331 extends a buckling portion 233b toward the battery pack clamping position 2110, the CTP battery pack 20 in the battery pack clamping position 2110 can be further pressed and fixed by the buckling portion 233b, preventing the CTP battery pack 20 from warping or bouncing upward during the shell tearing process, so that the CTP battery pack 20 is more firmly pressed on the placement plate 210 during the shell tearing process. Specifically, the lifting adjustment hole 233a extends vertically in an oval shape, so that the pressing buckle plate 2331 can move vertically along the lifting adjustment hole 233a, and the pressing buckle plate 2331 can be fixed at different heights by screwing the screw handle 2332. Finally, CTP battery packs 20 with different thicknesses and different heights can be pressed and fixed to adapt to CTP battery packs 20 of different models and different heights, further expanding the use range of the CTP battery pack shell tearing device 10. Specifically, the screw handle 2332 is a handle with a washer. Of course, this is not limited here, and those skilled in the art can also make other selections according to needs.

[0045] Combined with Figure 1As shown, in one embodiment, two linear guiding and sliding components 400 are fixedly provided on the machine platform 100; both ends of the mounting carriage 310 are respectively arranged on the two linear guiding and sliding components 400. It can be understood that since both ends of the mounting carriage 310 are respectively arranged on the two linear guiding and sliding components 400, the mounting carriage 310 can slide relative to the battery pack clamping mechanism 200 under the guiding action of the linear guiding and sliding components 400, thereby reducing the occurrence of the situation where the mounting carriage 310 slides off to one side. In this embodiment, the linear guiding and sliding component 400 includes a rotational drive 410, a threaded push rod 420, a track frame 430, and a conveying support 440; the track frame 430 is fixedly arranged on the machine platform 100, and the rotational drive 410 is installed on the track frame 430; the threaded push rod 420 is rotatably arranged on the track frame 430 and is connected to the power output end of the rotational drive 410; the conveying support 440 is slidably arranged on the track frame 430 and is threadedly connected to the threaded push rod 420; the end of the mounting carriage 310 is fixedly installed on the conveying support 440, so that the rotational drive 410 can be driven to rotate the threaded push rod 420, and then the threaded push rod 420 can drive the conveying support 440 and the mounting carriage 310 to slide synchronously. Among them, at least two bellows guards 450 are provided on the track frame 430, and each bellows guard 450 covers the threaded push rod 420 on one side of the conveying support 440, playing a good protective role.

[0046] In one embodiment, for better understanding, the usage process of the CTP battery pack shell tearing device 10 of the above embodiment is described as follows:

[0047] First, place the bottom plate of the shell of the CTP battery pack 20 upward on the battery pack clamping mechanism 200 for fixation, lift the end of the bottom plate of the shell of the CTP battery pack 20, so that the end of the bottom plate of the shell is clamped at the clamping end of the shell clamping component 320, drive the mounting carriage 310 to slide relative to the battery pack clamping mechanism 200, and the shell clamping component 320 moves synchronously and tears the bottom plate of the shell of the CTP battery pack 20, and finally the bottom plate of the shell of the CTP battery pack 20 can be quickly peeled off.

[0048] Compared with the prior art, the present disclosure has at least the following advantages:

[0049] 1) After the CTP battery pack 20 is placed above the battery pack clamping mechanism 200, since the installation carriage 310 is arranged across the top of the battery pack clamping mechanism 200, and the clamping end of the clamping shell assembly 320 on the installation carriage 310 faces the battery pack clamping mechanism 200, the housing 2020 of the CTP battery pack 20 can be clamped by the clamping end of the clamping shell assembly 320. Because both ends of the installation carriage 310 are slidably connected to the machine table 100, and the battery pack clamping mechanism 200 is fixedly arranged on the machine table 100, the installation carriage 310 can drive the clamping shell assembly 320 to slide relative to the battery pack clamping mechanism 200 synchronously. Thus, the housing 2020 of the CTP battery pack 20 can be clamped and torn, and finally the housing 2020 of the CTP battery pack 20 can be quickly peeled off.

[0050] 2) Compared with the disassembly tools for the CTP battery pack 20 in the prior art, the above-mentioned CTP battery pack shell tearing device 10 clamps and tears the housing 2020 of the CTP battery pack 20, so that the housing 2020 of the CTP battery pack 20 can be quickly peeled off to expose the battery cell units 2010 inside the CTP battery pack 20, and the battery cell units 2010 will not be damaged during the whole process. Thus, the integrity of the battery cell units 2010 as a whole can be maintained, and finally the battery cell units 2010 can be fully utilized in a cascaded manner after recycling.

[0051] The above-described embodiments merely represent several implementation manners of the present disclosure. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
