Description

Technical Field

[0001] The utility model relates to the technical field of power battery pack disassembly and recycling, in particular to a CTP battery pack disassembly device. Background Technique

[0002] This invention mainly solves the problem that it is difficult to strip the battery cells when disassembling the CTP battery pack. The battery pack with CTP structure uses a large amount of adhesives to connect and fix the battery cells. The traditional CTP battery cell disassembly methods include the low-temperature freezing method and the chemical agent immersion method. The low-temperature freezing method means storing the battery pack at minus 30 °C for more than 48 hours to weaken or lose the bonding effect of the glue, and then manually disassembling to take out the battery cells. The loss of disassembling the battery cells by the low-temperature freezing method is particularly large, and the yield is only 50% - 60%.

[0003] The chemical agent immersion method means immersing the entire battery pack in chemical agents to change the internal structure of the adhesive, so that the adhesive loses its viscosity, and then manually taking out the battery cells. Disassembling the battery cells by the chemical agent immersion method will produce industrial wastewater harmful to the environment, which not only increases the investment in environmental protection, but also easily damages the physical and mental health of workers. For this reason, we propose a CTP battery pack disassembly device. Content of the Utility Model

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Embodiment 1: Refer to Figures 1-5 , the present utility model provides a CTP battery pack disassembly device, including a workbench 1 and a display controller 24. The display controller 24 is placed on the ground near the workbench 1. A longitudinal guide rail assembly is installed on the workbench 1. The longitudinal guide rail assembly includes a support frame 2, a first mounting block 3, a longitudinal guide rail 4, and a longitudinal lead screw 5. Support frames 2 are fixedly installed on both sides of the upper surface of the workbench 1. A first mounting block 3 is fixedly connected to the outside of one of the support frames 2. A longitudinal lead screw 5 is rotatably installed in the inner cavity of the first mounting block 3. A longitudinal guide rail 4 is installed on the top of the support frame 2. One end of the longitudinal lead screw 5 is fixedly installed with a first handwheel 10.

[0024] A transverse guide rail assembly is installed on the longitudinal guide rail assembly. The transverse guide rail assembly includes a first slider 8, a mounting plate 6, an L-shaped fixing plate 7, a mounting rail 12, and a transverse lead screw 13. The lower surfaces at both ends of the two mounting rails 12 are fixedly installed with mounting plates 6. The bottom of the mounting plate 6 is fixedly connected with a first slider 8. An L-shaped fixing plate 7 is fixedly connected to one of the mounting plates 6. One end of the L-shaped fixing plate 7 is installed with a first driving block 9. A second mounting block 11 is installed on the mounting plate 6 by bolts, and a transverse lead screw 13 is rotatably installed in the inner cavity of the second mounting block 11. A transverse guide rail 14 is fixedly connected to the mounting rail 12. One end of the transverse lead screw 13 is fixedly connected with a second handwheel 15. The first slider 8 is slidably sleeved on the surface of the longitudinal guide rail 4, and the first driving block 9 is threadedly sleeved on the surface of the longitudinal lead screw 5.

[0025] A slitting module is provided on the transverse guide rail assembly. The slitting module includes a substrate 17, a cutting tool 21, and a cylinder 18. A cylinder 18 is fixedly installed in the middle of the substrate 17. The output end of the cylinder 18 extends below the substrate 17 and is fixedly installed with a cutting tool seat 20. A cutting tool 21 is installed at the bottom of the cutting tool seat 20. One side of the substrate 17 is connected with an adjustable mounting bracket 22. The adjustable mounting bracket 22 adopts a two-section structure, and the two sections can rotate relative to each other. An one-dimensional line laser 23 is installed on the adjustable mounting bracket 22. The irradiation angle of the one-dimensional line laser 23 can be adjusted according to the thickness of the battery pack to ensure that when the cylinder 18 is in the extreme contraction state, the position where the one-dimensional line laser 23 irradiates on the battery pack is exactly the position where the cutting tool 21 drops and contacts the battery pack. A camera 25 is installed on the other side of the substrate 17. The shooting angle of the camera 25 is inclined towards the cutting tool, and is used to shoot the position where the one-dimensional light emitted by the one-dimensional line laser 23 irradiates on the battery pack, and its angle can be adjusted manually.

[0026] The cylinder 18 is the power element in the disassembly process, the cutting tool 21 is the executing element in the disassembly process, the one-dimensional line laser 23 is the positioning element of the cutting tool 21 in the disassembly process, and the function of the camera 25 is to record in real time the position where the one-dimensional line laser 23 irradiates on the surface of the battery pack during the disassembly process and transmit the picture to the display controller 24.

[0027] The bottom of the substrate 17 is fixedly connected with a second slider 26. The second slider 26 is slidably sleeved on the surface of the transverse guide rail 14. The bottom of one end of the substrate 17 is fixedly installed with a second driving block 16. The second driving block 16 is threadedly sleeved on the surface of the transverse lead screw 13.

[0028] A guide post 19 is slidably installed inside the substrate 17, and the bottom end of the guide post 19 is fixedly connected with the upper surface of the cutting tool seat 20. The guide post 19 can ensure that the cutting tool seat 20 does not shift during the downward pressing action of the cylinder 18, ensuring stability.

[0029] The display controller 24 is electrically connected to the camera 25 and the substrate 17, and can record and save the process of battery pack disassembly. If the battery pack is damaged, there will be traces to follow.

[0030] In summary, for this CTP battery pack disassembly device, during use, the worker manually places the battery pack on the workbench 1. The worker operates the handwheel 10 in the longitudinal guide rail assembly and the handwheel 15 in the transverse guide rail assembly to enable the cutting module to fully cover the battery pack and move. The specific operation is as follows: First, rotate the handwheel 10. The rotation of the handwheel 10 drives the longitudinal lead screw 5 to rotate. The longitudinal lead screw 5 drives the driving block 9 adaptively installed on its surface to move longitudinally. The driving block 9 drives the L-shaped fixing plate 7 and then drives the mounting plate 6 to move. At the same time, the slider 1 8 moves along the longitudinal guide rail 4, thereby adjusting the position of the transverse guide rail assembly and the cutting module.

[0031] Then manually rotate the handwheel 15. The handwheel 15 drives the transverse lead screw 13 to rotate. The transverse lead screw 13 drives the driving block 2 16 to move, thereby driving the substrate 17 to move horizontally. At the same time, the slider 2 26 moves along the transverse guide rail 14, thereby adjusting the position of the cutting tool 21.

[0032] During the movement, the one-line laser 23 emits a laser beam that irradiates the battery pack. The position image of the one-line laser 23 irradiating the surface of the battery pack captured by the camera 25 will be displayed on the display controller 24, so as to facilitate the worker to determine whether the cutting tool 21 is aligned with the gap between the battery cells in the battery pack. Then operate the air cylinder 18 to drive the cutting tool 21 to move downward rapidly, so that the cutting tool 21 is inserted into the gap between the battery cells and the battery cell on the side is peeled off from the battery cell body. At least two or more workers are required to cooperate in this operation process. One person stands in front of the display controller 24 to control the cutting, and one person stands in front of the workbench 1 to adjust the position. That's all.

[0033] Finally, several points should be noted: First, in the description of this application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense.
