Abstract
Description

[0002] In battery production technology, it is necessary to cut and segment the rolled electrode sheets so that the size of the electrode sheets meets the actual production needs. The current device for cutting the electrode sheets includes a base, a cross bar and a cutting tool. The cross bar is set horizontally, and the cutting tool is movably connected to the cross bar in the horizontal direction. The two ends of the cross bar are elastically connected to the base in the vertical direction. During the cutting operation, the cutting operation of the electrode sheet is achieved by the movement of the cutting tool and the movement of the cross bar. The problem is that the closer the cutting tool is to the end of the cross bar, the easier it is for the cross bar to tilt relative to the horizontal direction. The tilt of the cross bar will make it difficult for the cutting tool to move smoothly in the horizontal direction. In addition, it will also cause the path of the cutting tool when moving in the horizontal direction to also include movement in the vertical direction, resulting in different cutting depths in different parts of the electrode sheet.

[0036] In the description of this application, reference to the terms "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of this application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.
[0037] The following describes the embodiments of the present application in conjunction with the accompanying drawings:
[0038] refer to Figure 1 and Figure 2 According to an embodiment of the present application, the cutting device is used to cut the pole piece. The cutting device includes a beam assembly 100 and a cutting module 200. The beam assembly 100 includes a guide beam 110 extending along a first direction. Along the first direction, the cutting module 200 is movably connected to the guide beam 110. The guide beam 110 is used to provide guidance for the movement of the cutting module 200 along the first direction. Along the second direction, the cutting module 200 is movably connected to the guide beam 110. The cutting module 200 moves relative to the guide beam 110 along the second direction to approach the pole piece and determine the cutting depth. The first direction is perpendicular to the second direction.
[0039] During the cutting operation, the cutting module 200 descends relative to the guide beam 110 along the second direction and approaches the electrode until the depth of the blade embedded in the electrode is consistent with the thickness of the electrode, so as to avoid the blade being embedded too deeply and damaging the supporting platform that supports the electrode, and to avoid the blade being embedded insufficiently and causing the electrode to not be cut. After the blade is embedded in the electrode, the cutting module 200 moves relative to the guide beam 110 along the first direction to achieve cutting of the electrode. During the process of the cutting module 200 being embedded in the electrode and moving along the first direction, the position of the guide beam 110 and the position of the cutting module 200 along the second direction remain unchanged, thereby ensuring the smoothness of the cutting operation and the consistency of the cutting depth. In addition, the blade direction of the cutting knife group 210 is set parallel to the first direction, so as to avoid the blade direction of the cutting knife group 210 being deflected relative to the cutting direction when the cutting module 200 moves along the first direction to cut the electrode, thereby achieving smooth cutting of the electrode.
[0040] Specifically, the first direction can be a horizontal direction, and the second direction can be a vertical direction. During the cutting operation, the electrode to be cut is placed under the guide beam 110, and the cutting knife group 210 is provided with a blade on one side facing downward. During the cutting operation, the cutting position on the electrode is changed by adjusting the position of the electrode to be cut relative to the cutting device. The staff presses down the cutting module 200 and drives the cutting module 200 to move close to the electrode relative to the beam assembly 100 in the second direction until the depth of the blade embedded in the electrode is consistent with the thickness of the electrode. On the basis of maintaining the downward pressing depth, the cutting module 200 can be pushed one way or reciprocatingly within the extension range of the guide beam 110 along the first direction to realize the blade cutting the electrode until the electrode is cut.
[0041] It should be noted that during the cutting operation, the staff can first push the cutting module 200 along the first direction to adjust the position of the cutting module 200, and then press the cutting module 200 down along the second direction to move it close to the pole piece, thereby maintaining the downward pressing depth of the cutting module 200, and then push the cutting module 200 along the first direction to achieve cutting of the pole piece.
[0042] Alternatively, the cutting module 200 can also move in the first direction and the second direction at the same time, and its actual movement trajectory is inclined relative to the first direction and the second direction, so as to facilitate the cutting edge of the cutting module 200 to reach the starting cutting position of the pole piece more quickly.
[0043] refer to Figures 2 to 5 In some embodiments, the cutting module 200 includes a cutting tool holder 220, which includes a first tool holder 221 and a second tool holder 222. The first tool holder 221 is movably connected to the guide beam 110 along a first direction, and the second tool holder 222 is movably connected to the first tool holder 221 along a second direction. The cutting knife assembly 210 is connected to the second tool holder 222. During cutting, the first tool holder 221 moves relative to the guide beam 110 in the first direction, driving the second tool holder 222 and the cutting knife assembly 210 to move in the first direction. The second tool holder 222 moves relative to the first tool holder 221 in the second direction, driving the cutting knife assembly 210 to move in the second direction, thereby achieving movement of the cutting knife assembly 210 relative to the guide beam 110 in the first and second directions. Along the second direction, the blade of the cutting knife assembly 210 extends beyond the end of the second knife holder 222 away from the guide beam 110 to prevent the second knife holder 222 from obstructing the contact between the blade and the pole piece.
[0044] Specifically, the first tool holder 221 can be connected to the guide beam 110 through a slide rail, and the second tool holder 222 can also be connected to the first tool holder 221 through a slide rail. Along the third direction, a portion of the first tool holder 221 protrudes relative to the guide beam 110, and the second tool holder 222 is connected to the first tool holder 221 at the protruding part of the first tool holder 221, so that the second tool holder 222 is located on one side of the guide beam 110, avoiding interference from the guide beam 110 when the second tool holder 222 moves relative to the first tool holder 221 along the second direction. Along the second direction, the cutting knife group 210 is connected to the lower end of the second tool holder 222, and along the third direction, the cutting knife group 210 is located on the side of the second tool holder 222 facing the guide beam 110, so that along the second direction, the cutting knife group 210 is located below the guide beam 110, which is convenient for cutting the pole piece with the guide beam 110 as a reference.
[0045] It should be noted that the first direction, the second direction and the third direction are perpendicular to each other.
[0046] refer to Figures 2 to 5 In some embodiments, the cutting tool holder 220 further includes an elastic member 223, which is connected to the first tool holder 221 and / or the second tool holder 222. The elastic member 223 is configured so that when the second tool holder 222 drives the cutting tool group 210 away from the guide beam 110 in the second direction, the elastic member 223 is elastically deformed under the joint action of the first tool holder 221 and the second tool holder 222. Thus, when the staff releases the second tool holder 222, the elastic member 223 rebounds and resets, driving the second tool holder 222 to drive the cutting tool group 210 to move along the second direction close to the guide beam 110, thereby resetting the second tool holder 222, eliminating the manual reset process of the staff, and is beneficial to improving the cutting efficiency of the pole piece.
[0047] For example, along the second direction, a holding portion is provided at the upper end of the second tool holder 222, and the elastic member 223 is connected to the holding portion, and the other end of the elastic member 223 abuts against the first tool holder 221. The second tool holder 222 moves relative to the guide beam 110 along the second direction, and the holding portion and the first tool holder 221 jointly squeeze the elastic member 223, causing the elastic member 223 to produce elastic deformation, thereby realizing the cutting operation of the electrode. After the cutting is completed, the user releases the second tool holder 222, and the elastic member 223 rebounds and resets. One end of the elastic member 223 abuts against the first tool holder 221, and the other end is connected to the holding portion, driving the second tool holder 222 to move along the second direction, thereby realizing the reset of the second tool holder 222.
[0048] It should be noted that the elastic member 223 can be a spring, and the number of the springs can be adjusted according to needs. For example, the number of the springs is five. Selecting an appropriate number of springs according to needs can provide a more appropriate elastic force, thereby avoiding the elastic force being too large, which makes it difficult for the staff to press down the second tool holder 222 in the second direction, and avoiding the elastic force being too small, which makes it difficult for the elastic member 223 to rebound and drive the second tool holder 222 to reset.
[0049] refer to Figure 2 and Figure 3 In other embodiments, one end of the elastic member 223 is connected to the first tool holder 221, and the other end of the elastic member 223 is connected to the second tool holder 222. When the staff presses the second tool holder 222 downward along the second direction, the second tool holder 222 drives the cutting knife group 210 away from the guide beam 110 along the second direction, and the elastic member 223 is stretched. When the staff releases the second tool holder 222, the elastic member 223 rebounds and resets. The elastic member 223 pulls the second tool holder 222 to reset through elastic force, thereby improving cutting efficiency.
[0050] refer to Figure 2 and Figure 3 In some embodiments, the first tool holder 221 is provided with a first through slot 2211 and a second through slot 2212. The first through slot 2211 penetrates the first tool holder 221 along the first direction, and the second through slot 2212 penetrates the first tool holder 221 along the second direction. The guide beam 110 is provided in the first through slot 2211, so that the first tool holder 221 can move along the extension direction of the guide beam 110, and the second tool holder 222 is provided in the second through slot 2212, so that the second tool holder 222 can move relative to the first tool holder 221 along the second direction. The relative arrangement of structures such as slide rails to achieve a movable connection is beneficial to reducing the space occupied by the cutting tool holder 220, thereby streamlining the structure of the cutting device.
[0051] refer to Figure 2 and Figure 3In some embodiments, the cutting module 200 includes a cutting tool holder 220, the cutting tool holder 220 is movably connected to the guide beam 110 along a first direction, and the cutting tool holder 220 is movably connected to the guide beam 110 along a second direction, that is, the cutting module 200 is movably connected to the guide beam 110 through the cutting tool holder 220. The cutting knife group 210 is rotatably connected to the cutting knife holder 220, and along the second direction, the blade of the cutting knife group 210 extends beyond the end of the cutting knife holder 220 away from the guide beam 110, so as to prevent the cutting knife holder 220 from hindering the blade of the cutting knife group 210 from cutting the pole piece. When cutting, the cutting knife group 210 can rotate as the cutting knife holder 220 moves along the first direction. Compared with the fixed blade, the rotation of the blade can make the blades of each part of the cutting knife group 210 participate in the cutting operation more evenly, which is beneficial to extending the service life of the cutting knife group 210 and making the cut surface of the pole piece more neat.
[0052] refer to Figures 3 to 5 In some embodiments, the cutting module 200 further includes a cutting knife holder 220, and the cutting knife group 210 includes a first mounting member 211, a cutting blade 212, and a second mounting member 213. The first mounting member 211 is rotatably connected to the cutting knife holder 220, and the cutting blade 212 is provided with a mounting through hole 2121. The first mounting member 211 includes a connected limiting portion 2111 and a bearing portion 2112. Along the third direction, the bearing portion 2112 extends from the position of the limiting portion 2111 to pass through the mounting through hole 2121. The second mounting member 213 is detachably connected to the cutting knife holder 220. The blade 212 is away from the side of the limiting portion 2111, the third direction is perpendicular to the first direction, and the third direction is perpendicular to the second direction. Along the third direction, the limiting portion 2111 abuts against one side of the cutting blade 212, and the second mounting member 213 abuts against the other side opposite to the cutting blade 212. The limiting portion 2111 and the second mounting member 213 are used to jointly fix the cutting blade 212 to prevent the cutting blade 212 from separating from the first mounting member 211, and to prevent the cutting blade 212 from rotating relative to the first mounting member 211, thereby ensuring the smoothness of the cutting operation.
[0053] Specifically, the limiting portion 2111 and the bearing portion 2112 are both circular, the diameter of the limiting portion 2111 is larger than the diameter of the bearing portion 2112, the cutting blade 212 is a circular blade, and the central area of the cutting blade 212 is provided with a mounting hole 2121. The diameter of the mounting hole 2121 can be basically consistent with the diameter of the bearing portion 2112, and there can be a clearance fit between the two to facilitate the disassembly and assembly of the cutting blade 212. The limiting portion 2111 extends along the third direction to pass through the mounting hole 2121, and the second mounting member 213 is connected to the limiting portion 2111 and is located on the side of the cutting blade 212 away from the limiting portion 2111. A thread may be provided on the outer peripheral wall of the limiting portion 2111 passing through the mounting hole 2121. The connection between the second mounting member 213 and the limiting portion 2111 may be through a threaded connection, which is convenient for adjusting the tightness of the cutting blade 212, and the cutting blade 212 can be detached by disassembling the second mounting member 213, which is convenient for replacing or maintaining the cutting blade 212.
[0054] refer to Figure 4 In other embodiments, along the third direction, at least two grooves 2131 are provided on the side of the second mounting member 213 facing away from the cutting blade 212. The two grooves 2131 are symmetrically distributed about the center of the second mounting member 213. The provision of the grooves 2131 facilitates the rotational assembly and disassembly of the second mounting member 213. Accordingly, a disassembly tool 240 for disassembling the second mounting member 213 is provided with two protrusions 241. The positions of the two protrusions 241 correspond to the positions of the two grooves 2131, respectively. The protrusions 241 correspond one-to-one with the grooves 2131. The second mounting member 213 can be assembled and disassembled by rotating the disassembly tool 240. By providing the grooves 2131 and cooperating with the disassembly tool 240, the second mounting member 213 can be made thinner, which helps to reduce the volume of the cutting device.
[0055] It should be noted that if the groove 2131 is not provided, the staff is required to directly rotate the second mounting member 213 , and the second mounting member 213 needs to have a certain thickness to facilitate the staff to hold.
[0056] refer to Figure 4 In other embodiments, with the center of the second mounting member 213 as the base point, a plurality of grooves 2131 are provided in a circular array on the side of the second mounting member 213 facing away from the cutting blade 212. Correspondingly, with the center of the disassembly and assembly tool 240 as the base point, a plurality of protrusions 241 are provided in a circular array on the surface of the disassembly and assembly tool 240, and the protrusions 241 on the disassembly and assembly tool 240 extend into the grooves 2131 one by one.
[0057] refer to Figure 4In some embodiments, the cutting knife assembly 210 further includes an anti-slip member 214. Along the third direction, the anti-slip member 214 is located between the cutting blade 212 and the limiting portion 2111, and / or, along the third direction, the anti-slip member 214 is located between the cutting blade 212 and the second mounting member 213. The anti-slip member 214 can be an anti-slip washer. The anti-slip member 214 can further prevent the cutting blade 212 from rotating relative to the first mounting member 211 by increasing the roughness of the contact surface, thereby facilitating a more stable cutting operation.
[0058] For example, the cutting knife group 210 includes two anti-slip parts 214. Along the third direction, one anti-slip part 214 is located between the limiting part 2111 and the cutting blade 212, and the other anti-slip part 214 is located between the cutting blade 212 and the second mounting part 213, thereby realizing double-sided anti-slip of the cutting blade 212, further ensuring that the limiting part 2111 and the second mounting part 213 stably fix the cutting blade 212, and ensuring the stability of cutting.
[0059] refer to Figures 3 to 5 In some embodiments, the cutting module 200 further includes a cutting blade holder 220 and a stopper 230. The cutting blade holder 220 is movably connected to the guide beam 110 along a first direction and movably connected to the guide beam 110 along a second direction. The cutting blade holder 220 is provided with a connecting shaft 2221. The cutting blade assembly 210 is provided with a first through hole 215. The stopper 230 is provided with a second through hole 231. The connecting shaft 2221 is sequentially passed through the first through hole 215 and the second through hole 231. The cutting blade holder 220 and the stopper 230 jointly abut against the cutting blade assembly 210 to secure the cutting blade assembly 210. The stopper 230 is detachably connected to the connecting shaft 2221. By removing the stopper 230, the cutting blade assembly 210 can be released, thereby releasing the entire cutting blade assembly 210 and facilitating maintenance or replacement of the cutting blade assembly 210.
[0060] Specifically, along the third direction, the part of the cutting knife holder 220 connected to the connecting shaft 2221 abuts against one side of the cutting knife group 210, and the limiting member 230 abuts against the other side opposite to the cutting knife group 210. The cutting knife group 210 and the connecting shaft 2221 can be rotatably connected through a bearing. The setting of the limiting member 230 is used to fix the cutting knife group 210, and realizes convenient disassembly and assembly of the cutting knife group 210 through a detachable connection with the connecting shaft 2221.
