Description

Technical Field

[0001] This utility model relates to the field of battery disassembly technology, and in particular to a cutting device and battery disassembly equipment. Background Technology

[0002] With increasing societal focus on environmental protection, new energy vehicles are becoming increasingly prevalent in people's daily lives. As a crucial component of new energy vehicles, power batteries need to be disassembled and replaced after reaching a certain level of degradation. To reduce the impact of end-of-life batteries on the ecosystem and the environment, they are often disassembled and recycled. Simultaneously, some waste power batteries often require disassembly and inspection to identify manufacturing process defects and improve the success rate of power battery production.

[0003] Currently, the mainstream method for disassembling batteries involves manually cutting open individual cells, removing the bare cells, and then manually cutting the binding adhesive to restore the cells to their individual cell pack state. However, cutting the binding adhesive manually is not only inefficient, but also prone to damaging the cell pack's separator, affecting the separation and purification of high-value metals in the electrodes. Utility Model Content

[0004] Therefore, it is necessary to provide a cutting device and battery disassembly equipment that can automatically cut the binding adhesive to improve cutting efficiency and prevent damage to the separator, in order to address the problem that manual cutting of the binding adhesive not only leads to low cutting efficiency but also easily damages the separator.

[0005] A cutting device, comprising:

[0006] A vision mechanism is used to obtain the thickness of the battery cell and the number of core packages included in the battery cell;

[0007] The control mechanism obtains the thickness of each core package included in the battery cell based on the thickness of the battery cell and the number of core packages obtained by the vision mechanism.

[0008] At least one cutting mechanism includes a lifting assembly and a cutting assembly, the cutting assembly being connected to the lifting assembly; the control mechanism controls the lifting assembly to move the cutting assembly along the thickness direction of the battery cell to between every two adjacent battery cells according to the thickness of each battery cell, the cutting assembly being used to cut the binding adhesive binding the battery cells between two battery cells.

[0009] In one embodiment, the cutting mechanism includes two cutting components disposed on the lifting component and forming a receiving gap between them for accommodating the battery cell. The two cutting components are respectively used to cut the binding adhesive at opposite ends of the battery cell.

[0010] In one embodiment, two of the cutting components are movably mounted on the lifting component so as to open or close to each other, thereby moving away from or closer to the binding adhesive of the battery cell located in the receiving gap.

[0011] In one embodiment, the cutting mechanism further includes an opening and closing component connected to the lifting component, and both cutting components are connected to the opening and closing component;

[0012] The opening and closing component is used to drive the movement of the two cutting components, causing the two cutting components to open or close.

[0013] In one embodiment, the cutting assembly includes a cutting drive assembly and a cutter. The cutting drive assembly is connected to the lifting assembly, and the cutter is connected to the cutting drive assembly. The cutting drive assembly is used to drive the cutter to move in order to cut the binding adhesive at one end of the battery cell.

[0014] In one embodiment, the cutting drive assembly includes a cutting drive component, a timing belt, and two pulleys. The cutting drive component is connected to the lifting assembly, one pulley is connected to the drive end of the cutting drive component, and the other pulley is connected to the lifting assembly. The timing belt is sleeved on the two pulleys, and the cutter is connected to the timing belt.

[0015] In one embodiment, the head of the cutter has an arc-shaped structure.

[0016] In one embodiment, the cutting device includes two cutting mechanisms arranged sequentially along the conveying direction of the battery cell. The upstream cutting mechanism is used to cut the binding adhesive at both ends of the core package with arcuate portions, and the downstream cutting mechanism is used to cut the binding adhesive at both ends of the core package with straight portions.

[0017] In one embodiment, the vision mechanism includes a CCD camera.

[0018] A battery dismantling device includes the aforementioned cutting device.

[0019] The aforementioned cutting device and battery disassembly equipment utilize a vision mechanism to acquire the thickness of the battery cell and the number of cell packs within it. A control mechanism, based on the cell thickness and number of cell packs obtained by the vision mechanism, calculates the thickness of each cell pack. Furthermore, the control mechanism controls a lifting assembly to precisely move the cutting assembly along the thickness direction of the battery cell to between adjacent cell packs, ensuring that the cutting assembly cuts the binding adhesive between the two packs. Compared to the existing method of manually cutting the binding adhesive, this cutting device automatically cuts the binding adhesive, significantly improving cutting efficiency. Simultaneously, the control mechanism controls the lifting assembly to precisely move the cutting assembly to between adjacent cells, allowing the cutting assembly to cut the binding adhesive between adjacent cells. This avoids accidentally damaging the cell pack's separator during cutting, facilitating the subsequent separation and purification of high-value metals from the electrodes.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] See Figure 1 One embodiment of this application provides a cutting device 100, including a vision mechanism 10, a control mechanism, and at least one cutting mechanism 20. Both the vision mechanism 10 and the cutting mechanism 20 are electrically connected to the control mechanism. The vision mechanism 10 is used to acquire the thickness of the battery cell 200 and the number of core packages 201 included in the battery cell 200, and transmits the data of the thickness of the battery cell 200 and the number of core packages 201 to the control mechanism. The control mechanism obtains the thickness of each core package 201 based on the thickness of the battery cell 200 and the number of core packages 201.

[0033] The thickness of the battery cell 200 is the sum of the thicknesses of all its constituent core packages 201. Once the thickness of the battery cell 200 and the number of core packages 201 are determined, the thickness of each core package 201 is the ratio of the thickness of the battery cell 200 to the number of core packages 201. See one specific embodiment. Figure 2 The battery cell 200 includes four core packages 201, which are stacked sequentially in the thickness direction. The thickness of the battery cell 200 obtained by the vision mechanism 10 is H, and the number of core packages 201 is four. In this case, the thickness h of each core package 201 is H / 4. In some other specific embodiments, when the battery cell 200 includes only one core package 201, the thickness of the battery cell 200 obtained by the vision mechanism 10 is H, and the number of core packages 201 is one. In this case, the thickness of each core package 201 is also H.

[0034] Optionally, the vision mechanism 10 includes a CCD camera, which can capture images of the cross-section of the battery cell 200. Based on its internally embedded vision algorithm, the CCD camera can determine the thickness of the battery cell 200 and the number of core packages 201 included in the battery cell 200. Generally, the core package 201 forms an arc portion 202 during winding. The CCD camera can identify the number of arcs included in the thickness direction of the battery cell 200; one arc represents one core package 201, thus determining the number of core packages 201 included in the battery cell 200.

[0035] It is conceivable that in some other embodiments, the arrangement of the vision mechanism 10 is not limited. For example, the vision mechanism 10 can also be other types of cameras or video cameras, as long as it can achieve the purpose of obtaining the thickness of the battery cell 200 and the number of core packages 201 included in the battery cell 200.

[0036] See Figure 3 The cutting mechanism 20 includes a lifting assembly 21 and a cutting assembly 22. The control mechanism can control the lifting assembly 21 to drive the cutting assembly 22 to move along the thickness direction of the cell 200 to between each two adjacent cell packs 201 according to the thickness of the core pack 201. The cutting assembly 22 is used to cut between two core packs 201. Figure 2 (Cut the adhesive at the center of the adhesive strip) Cut the adhesive strip 204 that binds the battery cell 200. For example... Figure 3 As shown, the lifting component 21 can drive the cutting component 22 along... Figure 3 The device moves in the Z-direction to position itself between each pair of adjacent core packages 201. The binding adhesive 204 is used to bind the core packages 201, thus securing them in place. (See also...) Figure 4 When binding the battery cell 200, the two ends of the binding adhesive 204 are connected to the bottommost core package 201 and the topmost battery cell 200, respectively, and the middle part of the binding adhesive 204 is connected to all core packages 201. It should be noted that when the battery cell 200 consists of only one core package 201, the binding adhesive 204 is not needed to bind the core package 201, and the binding adhesive 204 does not need to be cut.

[0037] Generally, before the cutting mechanism 20 cuts the binding adhesive 204, the cutting component 22 of the cutting mechanism 20 first zeros out, such as when the cutting component 22 is flush with the lower surface of the bottommost core package 201. When cutting the binding adhesive 204, the control mechanism controls the lifting component 21 to raise the cutting component 22 by the thickness of one core package 201, so that the cutting component 22 is positioned between the first and second core packages 201 from the bottom up, and so on. The number of layers of adhesive cut is the number of core packages 201 minus one. Of course, in some other embodiments, the position of the cutting component 22 zeroing out is not limited, as long as the thickness of the core package 201 allows the cutting component 22 to move between every two adjacent core packages 201.

[0038] The cutting device 100 provided in this application embodiment has a vision mechanism 10 that can obtain the thickness of the battery cell 200 and the number of core packages 201 included in the battery cell 200. The control mechanism obtains the thickness of each core package 201 included in the battery cell 200 based on the thickness of the battery cell 200 and the number of core packages 201 obtained by the vision mechanism 10. The control mechanism controls the lifting component 21 to drive the cutting component 22 to move precisely along the thickness direction of the battery cell 200 to between each two adjacent core packages 201, so as to ensure that the cutting component 22 cuts the binding adhesive 204 between two core packages 201. Compared to the existing technology where the binding adhesive 204 is cut manually, the cutting device 100 can automatically cut the binding adhesive 204, greatly improving the cutting efficiency. At the same time, the control mechanism can control the lifting component 21 to drive the cutting component 22 to move precisely between each pair of adjacent cells 200. The cutting component 22 cuts the binding adhesive 204 between the two adjacent cells 200, avoiding the problem of touching the core package 201 and tearing its diaphragm during cutting. This facilitates the separation and purification of high-value metals in the electrode sheet in subsequent processes.

[0039] In some embodiments, see further reference. Figure 1 The cutting device 100 includes two cutting mechanisms 20, which are arranged sequentially along the conveying direction of the battery cell 200. The upstream cutting mechanism 20 is used to cut the binding adhesive 204 at both ends of the core package 201 with the arc portion 202, and the downstream cutting mechanism 20 is used to cut the binding adhesive 204 at both ends of the core package 201 with the straight portion 203.

[0040] With the above configuration, when cutting the binding adhesive 204 of the battery cell 200, the upstream cutting mechanism 20 can cut the binding adhesive 204 at both ends of the core package 201 having the arc portion 202. Figure 4The U-direction is the cutting direction of the cutting assembly 22 for cutting the binding adhesive 204 at one end of the core package 201 with the arc portion 202. When the battery cell 200 is transported to the downstream cutting mechanism 20, the downstream cutting mechanism 20 can cut the binding adhesive 204 at both ends of the core package 201 with the straight portion 203. Figure 4 The V-direction is the cutting direction of the cutting component 22 in cutting the binding adhesive 204 at one end of the core package 201 with the straight portion 203. Since the upstream cutting mechanism 20 first cuts the binding adhesive 204 at the end of the core package 201 with the arc portion 202, and there is a gap between the arc portions 202, the cutting component 22 will not touch the diaphragm when cutting the binding adhesive 204 at the arc portion 202, and will not cut the diaphragm. Because the binding adhesive 204 at the arc portion 202 has been cut off, when the downstream cutting mechanism 20 cuts the binding adhesive 204, the cutting component 22 can be inserted between the two core packages 201 without cutting the diaphragm.

[0041] Further reading Figure 1 The cutting device 100 also includes a conveying mechanism 30, which conveys the battery cell 200 from the upstream cutting mechanism 20 to the downstream cutting mechanism 20, facilitating the cutting of the binding adhesive 204 by the cutting mechanism 20 and improving cutting efficiency. Optionally, the conveying mechanism 30 includes a conveyor belt, and both the conveyor belt and the cutting mechanism 20 are integrated on the bracket 40. Both cutting mechanisms 20 are located above the conveyor belt, which can convey the battery cell 200 to the area below the cutting mechanism 20 for the cutting mechanism 20 to cut the binding adhesive 204. In other embodiments, the specific configuration of the conveying mechanism 30 is not limited, as long as it can achieve the purpose of conveying the battery cell 200.

[0042] In some embodiments, see Figure 3 and Figure 5 The cutting mechanism 20 includes two cutting components 22, which are mounted on the lifting component 21 and form a receiving gap between them to accommodate the battery cell 200. The two cutting components 22 are used to cut the binding adhesive 204 at both ends of the battery cell 200. With this configuration, when the battery cell 200 is conveyed to the cutting mechanism 20, the two cutting components 22 of the cutting mechanism 20 cut the binding adhesive 204 from both ends of the battery cell 200, thereby improving the adhesive cutting efficiency.

[0043] It is understood that in other embodiments, the cutting mechanism 20 may also include only one cutting component 22, which first cuts the binding adhesive 204 at one end of the battery cell 200 and then cuts the binding adhesive 204 at the other end of the battery cell 200.

[0044] Furthermore, two cutting components 22 are movably mounted on the lifting component 21, allowing them to open or close relative to each other, thereby moving away from or closer to the binding adhesive 204 of the battery cell 200 located in the receiving gap. This arrangement serves two purposes: firstly, when the battery cell 200 is conveyed to a position close to the cutting mechanism 20, the two cutting components 22 move closer to the binding adhesive 204 of the battery cell 200 to cut the binding adhesive 204; after the binding adhesive 204 of the battery cell 200 is cut, the two cutting components 22 move away from the battery cell 200 to avoid interfering with the conveying of the battery cell 200; secondly, during the relative movement of the two cutting components 22, the width of the receiving gap changes, adapting to cutting binding adhesive 204 of battery cells 200 of different sizes.

[0045] Continue reading Figure 3 The cutting mechanism 20 also includes an opening and closing component 23, which is connected to the lifting component 21. Both cutting components 22 are connected to the opening and closing component 23. The opening and closing component 23 drives the two cutting components 22 to move, causing them to open or close. By setting the opening and closing component 23, the movement of the two cutting components 22 relative to the lifting component 21 is avoided manually, resulting in a high degree of automation.

[0046] In some embodiments, see further reference. Figure 3 and Figure 5 The cutting assembly 22 includes a cutting drive assembly 221 and a cutter 222. The cutting drive assembly 221 is connected to the opening and closing assembly 23, and the cutter 222 is connected to the cutting drive assembly 221. The cutting drive assembly 221 drives the cutter 222 to move, thereby cutting all the binding adhesive 204 at one end of the battery cell 200. For example, when cutting the binding adhesive 204 at the end of the core package 201 with the arc portion 202, the cutting drive assembly 221 drives the cutter 222 along... Figure 4 The cutter 222 moves in the U direction to cut the binding adhesive 204 at that end. When cutting the binding adhesive 204 at the end of the core package 201 with the straight portion 202, the cutter 222 can move in the V direction to cut the binding adhesive 204 at that end.

[0047] Continue reading Figure 3The cutting drive assembly 221 includes a cutting drive component 2211, a timing belt 2212, and two pulleys 2213. The cutting drive component 2211 is connected to the opening and closing assembly 23. One pulley 2213 is connected to the drive end of the cutting drive component 2211, and the other pulley 2213 is connected to the opening and closing assembly 23. The timing belt 2212 is fitted onto the two pulleys 2213, and the cutter 222 is connected to the timing belt 2212. The cutting drive component 2211 drives the pulleys 2213 to rotate, the pulleys 2213 drive the timing belt 2212 to move, and the timing belt 2212 drives the cutter 222 to move along the extension direction of the timing belt 2212, so that the cutter 222 can cut all the binding straps at one end of the battery cell 200. Optionally, the cutting drive component 2211 can be a motor or a cylinder, etc.

[0048] In some embodiments, the head of the cutter 222 is an arc-shaped structure. The arc-shaped structure of the head of the cutter 222 makes it easier to extend between the two core packages 201, avoiding the phenomenon of touching the diaphragm and cutting the diaphragm.

[0049] It should be noted that this application does not limit the arrangement of the lifting assembly 21 and the opening / closing assembly 23. In some specific embodiments, the lifting assembly 21 includes a cylinder, which drives the opening / closing assembly 23 to rise and fall, thereby driving the cutting assembly 22 to rise and fall. The opening / closing assembly 23 includes a screw, with the threads at both ends of the screw rotating in opposite directions. The two cutting assemblies 22 are respectively connected to the two ends of the screw, and the rotation of the screw causes the two cutting assemblies 22 to move closer to or further away from each other.

[0050] Another embodiment of this application also provides a battery disassembly device including the above-described cutting device 100. Since the cutting device 100 has beneficial effects, the battery disassembly device including the cutting device 100 has the same beneficial effects, which will not be described in detail here.

[0051] Furthermore, in addition to the aforementioned cutting device 100, the battery disassembly equipment also includes a cell unpacking device, which enables the cell 200 to be removed from the casing, and the cutting device 100 is used to cut the binding adhesive 204 of the cell 200 that has been removed from the casing.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
