Description

Technical Field

[0001] This application relates to the field of battery cell processing equipment technology, and in particular to a smoothing component, a cutting mechanism and a battery cell winding machine. Background Technology

[0002] During the battery cell winding process, a smoothing assembly is needed to flatten the tabs on the electrode sheets to prevent them from folding over. Additionally, considering the need to cut the separator during cell winding, a cutter is typically required to cut the separator.

[0003] However, during the process of winding battery cells using a battery cell winding machine, interference may occur between the smoothing components and the cutter, affecting the normal operation of the battery cell winding machine. Utility Model Content

[0004] This application discloses a smoothing component, a cutting mechanism, and a cell winding machine, which can avoid interference between the smoothing component and the cutter, thereby ensuring the normal operation of the cell winding machine.

[0005] To achieve the above objectives, in a first aspect, this application discloses a smoothing component, comprising:

[0006] First driving component;

[0007] Mounting base, the mounting base is mounted on the moving end of the first driving component;

[0008] A second driving member, the second driving member being mounted on the mounting base; and...

[0009] A smoothing component, which is connected to the movable end of the second drive component.

[0010] Optionally, the first driving member is used to drive the mounting base to move along a first direction, and the second driving member is used to drive the smoothing member to move along a second direction, wherein the first direction is different from the second direction.

[0011] Since the mounting base is installed on the moving end of the first driving member, the second driving member is installed on the mounting base, and the smoothing member is connected to the moving end of the second driving member, when the smoothing component is applied to the cell winding machine and it is necessary to smooth the electrode tabs wound on the winding needle by the smoothing component, firstly, the first driving member can drive the mounting base to move in a first direction, which can be the radial direction of the winding needle, so that the smoothing component abuts against the electrode tab in the radial direction of the winding needle. When the smoothing component abuts against the electrode tab, as the electrode tab rotates with the winding needle, the smoothing component can achieve the purpose of smoothing the electrode tab.

[0012] When the diaphragm needs to be cut at the coil needle by the cutter, in order to avoid interference between the cutter and the smoothing component, the second drive can drive the smoothing component to move along the second direction, which can be the axis of the coil needle. When the smoothing component moves along the axis of the coil needle, the smoothing component can move beyond the cutter along the axis of the coil needle (the second direction) so that the smoothing component and the cutter are misaligned. In this way, interference between the smoothing component and the cutter can be avoided, thereby ensuring the normal operation of the cell winding machine.

[0013] Optionally, the smoothing component further includes:

[0014] A first connector is adjustablely connected to the moving end of the second drive member along a first direction, and the smoothing member is connected to the first connector.

[0015] Since the smoothing component is connected to the first connecting component, and the first connecting component is adjustablely connected to the moving end of the second driving component along the first direction, when the position of the first connecting component is adjusted along the first direction, the smoothing component can be moved along the first direction, thereby achieving the purpose of adjusting the position of the smoothing component along the first direction. This makes the adjustment of the smoothing component along the first direction very convenient, and makes the installation position of the smoothing component relative to the moving end of the second driving component along the first direction more flexible.

[0016] Optionally, the smoothing component further includes a first locking member, the first connector having a first strip hole extending along the first direction, and the locking end of the first locking member being detachably connected to the moving end of the second drive member through the first strip hole.

[0017] Since the first slot extends along the first direction, the locking end of the first locking member is detachably connected to the moving end of the second driving member through the first slot. Therefore, when it is necessary to adjust the position of the first connecting member relative to the moving end of the second driving member along the first direction, the locking end of the first locking member can be released from the moving end of the second driving member. Then, the first connecting member can be moved along the extension direction of the first slot until it is moved to the target position. Then, the locking end of the first locking member can be locked to the moving end of the second driving member again, and the limiting end of the first locking member is limited to the side of the first connecting member opposite to the moving end of the second driving member. In this way, the first connecting member can be kept in the target position.

[0018] As can be seen, by providing a first strip-shaped hole extending in the first direction on the first connector, and allowing the locking end of the first locking member to be detachably connected to the moving end of the second driving member through the first strip-shaped hole, the purpose of making the first connector adjustablely connected to the moving end of the second driving member in the first direction can be achieved, which is very convenient and quick.

[0019] Optionally, the smoothing component further includes:

[0020] A second connector is adjustablely connected to the first connector along a second direction, and the smoothing member is connected to the second connector.

[0021] Since the smoothing component is connected to the second connector, and the second connector is adjustablely connected to the first connector along the second direction, when the position of the second connector is adjusted along the second direction, the smoothing component can be moved along the second direction, thereby achieving the purpose of adjusting the position of the smoothing component along the second direction, making the installation position of the smoothing component relative to the second connector along the second direction more flexible.

[0022] Optionally, the smoothing member is rotatably connected to the second connecting member about a first axis.

[0023] Since the smoothing member is rotatably connected to the second connector about the first axis, the pitch angle of the smoothing member can be adjusted when the smoothing member is rotated about the first axis, thereby enabling the smoothing member to smooth the tabs better.

[0024] Optionally, the smoothing component further includes a second locking member, the second connector having an arc-shaped hole, the locking end of the second locking member being detachably connected to the smoothing member through the arc-shaped hole along the second direction, and the second locking member being slidable along the extension direction of the arc-shaped hole.

[0025] Since the locking end of the second locking member is detachably connected to the smoothing member through the arc-shaped hole along the second direction, and the second locking member can slide along the extension direction of the arc-shaped hole, on the one hand, the cooperation between the second locking member and the arc-shaped hole can guide the smoothing member to rotate around the first axis, making the smoothing member rotate more smoothly around the first axis. On the other hand, when the smoothing member is adjusted to the correct position around the first axis, locking the locking end of the second locking member to the smoothing member can achieve the purpose of locking the smoothing member to the second connecting member.

[0026] Secondly, this application discloses a cutting mechanism, including the smoothing component described in any of the first aspects above.

[0027] Since the smoothing component can move in the second direction, when the smoothing component is applied to the cutting mechanism, the smoothing component can move in the second direction beyond the cutter, so that the smoothing component and the cutter are misaligned. In this way, interference between the smoothing component and the cutter can be avoided.

[0028] Optionally, it also includes:

[0029] A first guide roller is rotatably mounted on the mounting base and extends in a second direction;

[0030] A second guide roller, rotatably mounted on the mounting base and extending along the second direction; and,

[0031] A cutter is disposed on the mounting base and located radially between the first and second rollers along the first roller.

[0032] Optionally, the second driving member is used to drive the smoothing member to move along the second direction, so that the smoothing member moves along the second direction to a position other than any of the first roller, the second roller, and the cutter.

[0033] Since the first guide roller, the second guide roller, and the cutter are mounted on the mounting base, and the mounting base is mounted on the moving end of the first drive member, the second drive member is mounted on the mounting base, and the smoothing member is connected to the moving end of the second drive member, that is, the first guide roller, the second guide roller, the cutter, and the smoothing member are all connected to the mounting base. Therefore, when the first drive member drives the mounting base to move along the first direction, in addition to driving the first guide roller, the second guide roller, and the cutter to move closer to the winding needle along the first direction to cut the diaphragm, it can also drive the smoothing member to move closer to the winding needle along the first direction to abut against the electrode tab to smooth the electrode tab. In other words, the function of cutting the diaphragm and the function of smoothing the electrode tab can be achieved by the same drive member (the first drive member). In this way, there is no need to set up two separate drive members. On the one hand, it can reduce the cost of the cutting mechanism, and on the other hand, it can make the structure of the cutting mechanism more compact.

[0034] Furthermore, since the second driving member can drive the smoothing member to move along the second direction, so that the smoothing member moves along the second direction beyond any of the first roller, the second roller, and the cutter, that is, the smoothing member moves along the second direction beyond any of the first roller, the second roller, and the cutter, the smoothing member can be offset from any of the first roller, the second roller, and the cutter along the second direction. In this way, interference between the smoothing member and the first roller, the second roller, and the cutter can be avoided.

[0035] Furthermore, since the cutter is located between the first and second rollers along the radial direction of the first roller, when the first drive unit drives the first roller, the second roller and the cutter to move closer to the winding needle along the first direction, the first roller and the second roller can abut against the diaphragm on both sides of the cutter, so that the diaphragm on both sides of the cutter along the radial direction of the first roller can be fixed, which is beneficial for the cutter to cut the diaphragm.

[0036] Optionally, it also includes:

[0037] A movable base, which is slidably disposed on the mounting base along a first direction; and,

[0038] A third driving member is disposed on the mounting base and the movable end of the third driving member is connected to the movable base;

[0039] The first roller is rotatably mounted on the movable seat.

[0040] Since the first guide roller is rotatably mounted on the movable seat, and the movable seat is slidably disposed on the mounting seat along the first direction, and the third drive member is disposed on the mounting seat and the moving end of the third drive member is connected to the movable seat, when the third drive member drives the movable seat to move along the first direction, it can drive the first guide roller to move along the first direction, thereby allowing the position of the first guide roller to be adjusted independently along the first direction, so that the position of the first guide roller along the first direction can be flexibly adjusted, which is conducive to the first guide roller and the second guide roller being better matched with the winding needle in position.

[0041] Thirdly, this application discloses a battery cell winding machine, including the cutting mechanism described in any of the second aspects above.

[0042] Since the cutting mechanism can prevent interference between the smoothing part and the cutter, the normal operation of the battery cell winding machine can be well guaranteed when the cutting mechanism is included.

[0043] Optionally, it also includes:

[0044] curling needles;

[0045] The first driving member is used to drive the mounting base to move along a first direction, so as to cause the smoothing member to move closer to or further away from the winding needle in the radial direction. The second driving member is used to drive the smoothing member to move along a second direction, so as to cause the smoothing member to move along the axial direction of the winding needle.

[0046] Since the first driving member can drive the mounting base to move in the first direction, when the first driving member drives the mounting base to move in the first direction, it can drive the smoothing member to move radially toward the winding needle, so that when the smoothing member abuts against the electrode tabs wound on the electrode sheet on the winding needle, the purpose of smoothing the electrode tabs can be achieved. When the second driving member drives the smoothing member to move in the second direction, so that the smoothing member moves axially along the winding needle, it can move along the axial direction (second direction) of the winding needle beyond the cutter, so that the smoothing member and the cutter are misaligned, thereby avoiding interference between the smoothing member and the cutter.

[0047] Compared with the prior art, the beneficial effects of this application are as follows:

[0048] In this application, since the mounting base is installed on the moving end of the first driving member, the second driving member is installed on the mounting base, and the smoothing member is connected to the moving end of the second driving member, when the smoothing component is applied to the cell winding machine and it is necessary to smooth the electrode tabs wound on the winding needle by the smoothing component, firstly, the first driving member can drive the mounting base to move in a first direction, which can be the radial direction of the winding needle, so that the smoothing component abuts against the electrode tab in the radial direction of the winding needle. When the smoothing component abuts against the electrode tab, as the electrode tab rotates with the winding needle, the smoothing component can achieve the purpose of smoothing the electrode tab.

[0049] When the diaphragm needs to be cut at the coil needle by the cutter, in order to avoid interference between the cutter and the smoothing component, the second drive can drive the smoothing component to move along the second direction, which can be the axis of the coil needle. When the smoothing component moves along the axis of the coil needle, the smoothing component can move beyond the cutter along the axis of the coil needle (the second direction) so that the smoothing component and the cutter are misaligned. In this way, interference between the smoothing component and the cutter can be avoided, thereby ensuring the normal operation of the cell winding machine. Attached Figure Description

[0075] Before explaining the technical solution of this application, the background technology of this application shall be explained first.

[0076] During the battery cell winding process, a smoothing assembly is needed to flatten the tabs on the electrode sheets to prevent them from folding over. Additionally, considering the need to cut the separator during cell winding, a cutter is typically required to cut the separator.

[0077] However, during the winding process of battery cells using a cell winding machine, interference may occur between the smoothing component and the cutter, affecting the normal operation of the cell winding machine. Therefore, this application provides a smoothing component to solve the aforementioned problem.

[0078] The technical solution of this application will be described below with reference to specific embodiments and accompanying drawings.

[0079] Figure 1 This is a schematic diagram of the structure of a cutting mechanism 200 provided in one embodiment of this application. Figure 2 yes Figure 1 The structural diagram of the smoothing component 100 with some parts omitted. Figure 3 yes Figure 1 A schematic diagram of the cutting mechanism 200 applied to the cell winding machine 300.

[0080] See Figure 1 , Figure 2 and Figure 3 The smoothing component 100 includes a first driving member 1, a mounting base 2, a second driving member 3, and a smoothing member 4. The mounting base 2 is mounted on the movable end of the first driving member 1, the second driving member 3 is mounted on the mounting base 2, and the smoothing member 4 is connected to the movable end of the second driving member 3. The first driving member 1 is used to drive the mounting base 2 along a first direction (…). Figure 1The second driving member 3 moves along the X-axis direction, and the second driving member 4 is used to drive the smoothing member 4 along the second direction ( Figure 1 The movement is along the Y-axis, and the first and second directions are different.

[0081] In this embodiment, since the mounting base 2 is mounted on the moving end of the first driving member 1, the second driving member 3 is mounted on the mounting base 2, and the smoothing member 4 is connected to the moving end of the second driving member 3, when the smoothing component 100 is applied to the cell winding machine 300 and it is necessary to smooth the electrode tabs wound on the winding needle 301 by the smoothing component 100, firstly, the first driving member 1 can drive the mounting base 2 to move in a first direction, which can be the radial direction of the winding needle 301, so that the smoothing member 4 abuts against the electrode tab in the radial direction of the winding needle 301. When the smoothing member 4 abuts against the electrode tab, as the electrode tab rotates with the winding needle 301, the smoothing member 4 can achieve the purpose of smoothing the electrode tab.

[0082] When it is necessary to cut the diaphragm at the coil needle 301 by the cutter 203, in order to avoid interference between the cutter 203 and the smoothing member 4, the second drive member 3 can drive the smoothing member 4 along the second direction ( Figure 1 The smoothing member 4 moves along the Y-axis direction, which can be the axial direction of the winding needle 301. When the smoothing member 4 moves along the axial direction of the winding needle 301, the smoothing member 4 can move along the axial direction of the winding needle 301 (second direction) beyond the cutter 203, so that the smoothing member 4 and the cutter 203 are misaligned. In this way, the interference between the smoothing member 4 and the cutter 203 can be avoided, thereby ensuring the normal operation of the battery cell winding machine 300.

[0083] It should be noted that the first driving component 1 mentioned above can be a cylinder, an electric cylinder, etc. Of course, the first driving component 1 can also be a structure composed of a lead screw and nut structure and a motor, as long as it can drive the mounting base 2 to move in the first direction. This embodiment does not limit this.

[0084] In addition to driving the smoothing member 4 to move along the first direction, so that the smoothing member 4 moves closer to the winding needle 301 along the radial direction of the winding needle 301 and abuts against the electrode tab, the first driving member 1 can also drive the smoothing member 4 to move gradually away from the winding needle 301 along the radial direction of the winding needle 301 as the winding needle 301 rotates, so that the smoothing member 4 can be matched with the electrode with the gradually increasing diameter in position.

[0085] The structure of the second driving component 3 can be the same as or similar to that of the first driving component 1. For details, please refer to the description of the first driving component 1 in the above embodiments. This embodiment will not repeat the description here.

[0086] The first direction and the second direction can be perpendicular. Of course, there can also be other possible angles between the first direction and the second direction. For example, the angle between the first direction and the second direction can be 92°, 93°, etc. This embodiment does not limit this.

[0087] The smoothing component 4 can be a plate-like structure or any other shape, as long as it can smooth the tabs. This embodiment does not limit this.

[0088] In some embodiments, see Figure 2 , Figure 4 and Figure 5 , Figure 4 yes Figure 2 A schematic diagram of the smoothing component 100 from another perspective. Figure 5 yes Figure 1 A partial enlarged view at position A shows that the smoothing component 100 also includes a first connector 5, which extends along a first direction ( Figure 4 The smoothing component 4 is adjustablely connected to the moving end of the second drive component 3 (in the X-axis direction), and is connected to the first connecting component 5.

[0089] Since the smoothing component 4 is connected to the first connecting component 5, the first connecting component 5 is along the first direction ( Figure 4 The first connecting member 5 is adjustablely connected to the moving end of the second driving member 3 in the X-axis direction. Therefore, when the position of the first connecting member 5 is adjusted in the first direction, the smoothing member 4 can be moved in the first direction, thereby achieving the purpose of adjusting the position of the smoothing member 4 in the first direction. This makes the adjustment of the smoothing member 4 in the first direction very convenient, and makes the installation position of the smoothing member 4 relative to the moving end of the second driving member 3 in the first direction more flexible.

[0090] Wherein, the first connecting member 5 is along the first direction ( Figure 4 There are several ways to adjustably connect the moving end of the second drive member 3 (in the X-axis direction). In one possible implementation, see [link to relevant documentation]. Figure 2 and Figure 4 The smoothing component 100 also includes a first locking member 6, and the first connecting member 5 is provided with a locking element along a first direction ( Figure 4 The first strip hole 51 extends in the X-axis direction. The locking end of the first locking member 6 passes through the first strip hole 51 and is detachably connected to the moving end of the second driving member 3. The limiting end of the first locking member 6 is limited to the side of the first connecting member 5 opposite to the moving end of the second driving member 3.

[0091] Since the first slot 51 extends along the first direction, the locking end of the first locking member 6 is detachably connected to the moving end of the second driving member 3 through the first slot 51. The limiting end of the first locking member 6 is located on the side of the first connecting member 5 opposite to the moving end of the second driving member 3. Therefore, when it is necessary to lock along the first direction ( Figure 4 When adjusting the position of the first connecting member 5 relative to the moving end of the second driving member 3 (in the X-axis direction), the locking end of the first locking member 6 can be released from the moving end of the second driving member 3. Then, the first connecting member 5 can be moved along the extension direction of the first strip hole 51 until the first connecting member 5 is moved to the target position. Then, the locking end of the first locking member 6 can be locked to the moving end of the second driving member 3 again, and the limiting end of the first locking member 6 is limited to the side of the first connecting member 5 away from the moving end of the second driving member 3. In this way, the first connecting member 5 can be kept in the target position.

[0092] It can be seen that by setting a first direction on the first connector 5 ( Figure 4 A first strip-shaped hole 51 extends in the X-axis direction, allowing the locking end of the first locking member 6 to pass through the first strip-shaped hole 51 and be detachably connected to the moving end of the second driving member 3. The limiting end of the first locking member 6 is located on the side of the first connecting member 5 opposite to the moving end of the second driving member 3, thus enabling the first connecting member 5 to move along the first direction (X-axis direction). Figure 4 The purpose of adjusting the connection (in the X-axis direction) to the moving end of the second drive unit 3 is very convenient and quick to achieve.

[0093] Of course, the first connector 5 can also be used in other ways to achieve the first direction ( Figure 4 The purpose of the adjustable connection (in the X-axis direction) to the moving end of the second drive member 3 is not listed in detail in this embodiment.

[0094] It should be noted that the first locking member 6 mentioned above can be a screw or the like, and this embodiment does not limit this. The first connecting member 5 mentioned above can be a plate-like structure or any other arbitrary shape, and this embodiment does not limit this.

[0095] In some embodiments, see Figure 2 and Figure 5 The smoothing component 100 also includes a second connector 7, the second connector 7 being along a second direction ( Figure 2 The smoothing part 4 is adjustablely connected to the first connector 5 (in the Y-axis direction), and the smoothing part 4 is connected to the second connector 7.

[0096] Since the smoothing member 4 is connected to the second connecting member 7, the second connecting member 7 is along the second direction ( Figure 2The second connector 7 is adjustablely connected to the first connector 5 in the Y-axis direction. Therefore, when the position of the second connector 7 is adjusted in the second direction, the smoothing component 4 can be moved in the second direction, thereby achieving the purpose of adjusting the position of the smoothing component 4 in the second direction, making the installation position of the smoothing component 4 relative to the second connector 7 in the second direction more flexible.

[0097] Wherein, the aforementioned second connector 7 is along the second direction ( Figure 2 There are several ways to adjustably connect the component (in the Y-axis direction) to the first connector 5. In one possible implementation, see [link to relevant documentation]. Figure 2 and Figure 5 The smoothing component 100 also includes a third locking member 9, and the second connecting member 7 is provided with a locking element along the second direction ( Figure 2 The second strip hole 72 extends in the Y-axis direction. The locking end of the third locking member 9 passes through the second strip hole 72 and is detachably connected to the first connecting member 5. The limiting end of the third locking member 9 is limited to the side of the second connecting member 7 away from the first connecting member 5.

[0098] The structure of the second strip hole 72 can be similar to that of the first strip hole 51, and the structure of the third locking member 9 can be similar to that of the first locking member 6. For details, please refer to the description of the second strip hole 72 and the first locking member 6 in the above embodiments. This embodiment will not repeat the description here.

[0099] In some embodiments, see Figure 5 The smoothing component 4 is rotatably connected to the second connecting component 7 about the first axis O1, and the first axis O1 is perpendicular to the second direction ( Figure 5 Parallel to the Y-axis direction.

[0100] Since the smoothing member 4 is rotatably connected to the second connecting member 7 about the first axis O1, the first axis O1 and the second direction ( Figure 5 Since the smoothing component 4 is parallel to the Y-axis direction, when the smoothing component 4 is rotated around the first axis O1, the pitch angle of the smoothing component 4 can be adjusted, thereby enabling the smoothing component 4 to smooth the tabs better.

[0101] In some embodiments, see Figure 4 and Figure 5 The smoothing component 100 also includes a second locking member 8. The second connecting member 7 is provided with an arc-shaped hole 71. The locking end of the second locking member 8 passes through the arc-shaped hole 71 along the second direction and is detachably connected to the smoothing member 4. The second locking member 8 can slide along the extension direction of the arc-shaped hole 71. The limiting end of the second locking member 8 is limited to the side of the second connecting member 7 away from the smoothing member 4.

[0102] Since the locking end of the second locking member 8 is detachably connected to the smoothing member 4 through the arc-shaped hole 71 along the second direction, and the second locking member 8 can slide along the extension direction of the arc-shaped hole 71, on the one hand, the cooperation between the second locking member 8 and the arc-shaped hole 71 can guide the smoothing member 4 to rotate around the first axis O1, making the smoothing member 4 rotate more smoothly around the first axis O1. On the other hand, when the smoothing member 4 is adjusted to the correct position around the first axis O1, locking the locking end of the second locking member 8 to the smoothing member 4 can achieve the purpose of locking the smoothing member 4 to the second connecting member 7.

[0103] The second locking element 8 mentioned above can be a screw or the like, and this embodiment does not limit it.

[0104] An embodiment of this application also provides a cutting mechanism 200, see [link to relevant documentation] Figure 1 The cutting mechanism 200 includes a smoothing component 100.

[0105] The structure of the smoothing component 100 can be the same as that of any of the smoothing components 100 described in the above embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description in the above embodiments. This embodiment will not repeat the description here.

[0106] In this embodiment, since the smoothing member 4 can move along the second direction (axial direction of the coil needle 301), when the smoothing component 100 is applied to the cutting mechanism 200, the smoothing member 4 can move along the second direction beyond the cutter 203, so that the smoothing member 4 and the cutter 203 are misaligned. In this way, the interference between the smoothing member 4 and the cutter 203 can be avoided.

[0107] In some embodiments, see Figure 1 and Figure 3 The cutting mechanism 200 also includes a first guide roller 201, a second guide roller 202, and a cutter 203, wherein the first guide roller 201 is rotatably mounted on the mounting base 2 and along the second direction ( Figure 1 Extending in the Y-axis direction, the second guide roller 202 is rotatably mounted on the mounting base 2 and extends along the second direction. The cutter 203 is disposed on the mounting base 2 and located radially between the first guide roller 201 and the second guide roller 202. The second driving member 3 is used to drive the smoothing member 4 to move along the second direction, so that the smoothing member 4 moves along the second direction to a position other than any of the first guide roller 201, the second guide roller 202, and the cutter 203.

[0108] Since the first guide roller 201, the second guide roller 202, and the cutter 203 are disposed on the mounting base 2, and since the mounting base 2 is mounted on the moving end of the first drive member 1, the second drive member 3 is mounted on the mounting base 2, and the smoothing member 4 is connected to the moving end of the second drive member 3, that is, the first guide roller 201, the second guide roller 202, the cutter 203, and the smoothing member 4 are all connected to the mounting base 2, therefore, when the first drive member 1 drives the mounting base 2 along the first direction ( Figure 1 When the cutting mechanism moves along the X-axis, in addition to driving the first roller 201, the second roller 202, and the cutter 203 to move along the first direction towards the winding needle 301 to cut the diaphragm, it can also drive the smoothing member 4 to move along the first direction towards the winding needle 301 to abut against the electrode tab to smooth the electrode tab. That is, the functions of cutting the diaphragm and smoothing the electrode tab can be achieved by the same driving member (first driving member 1). In this way, there is no need to set up two separate driving members. On the one hand, the cost of the cutting mechanism 200 can be reduced, and on the other hand, the structure of the cutting mechanism 200 can be made more compact.

[0109] In addition, since the second driving member 3 can drive the smoothing member 4 along the second direction ( Figure 1 The smoothing member 4 moves along the Y-axis direction to move beyond any one of the first roller 201, the second roller 202, and the cutter 203. In simpler terms, the smoothing member 4 moves along the second direction beyond any one of the first roller 201, the second roller 202, and the cutter 203. Therefore, the smoothing member 4 can be offset from any one of the first roller 201, the second roller 202, and the cutter 203 along the second direction. In this way, interference between the smoothing member 4 and the first roller 201, the second roller 202, and the cutter 203 can be avoided.

[0110] Furthermore, since the cutter 203 is located radially between the first roller 201 and the second roller 202 along the first roller 201, when the first driving member 1 drives the first roller 201, the second roller 202 and the cutter 203 to move closer to the winding needle 301 along the first direction, the first roller 201 and the second roller 202 can abut against the diaphragm on both sides of the cutter 203, so that the diaphragm on both sides of the cutter 203 along the radial direction of the first roller 201 can be fixed, which is beneficial for the cutter 203 to cut the diaphragm.

[0111] In some embodiments, see Figure 1 The cutting mechanism 200 also includes a movable seat 204 and a third driving member 205, wherein the movable seat 204 is along a first direction ( Figure 1 The first roller 201 is rotatably mounted on the moving seat 204. The third drive member 205 is mounted on the mounting seat 2 and the moving end of the third drive member 205 is connected to the moving seat 204.

[0112] Since the first guide roller 201 is rotatably mounted on the movable seat 204, and the movable seat 204 is slidably disposed on the mounting seat 2 along the first direction, and the third drive member 205 is disposed on the mounting seat 2 and the moving end of the third drive member 205 is connected to the movable seat 204, when the third drive member 205 drives the movable seat 204 to move along the first direction, it can drive the first guide roller 201 to move along the first direction, thereby allowing the position of the first guide roller 201 to be adjusted independently along the first direction, so that the position of the first guide roller 201 along the first direction can be flexibly adjusted, which is conducive to the first guide roller 201 and the second guide roller 202 being better matched with the winding needle 301 in position.

[0113] The third driving component 205 can be a cylinder, an electric cylinder, or any structure capable of driving the movable seat 204 to move along the first direction. This embodiment does not limit the third driving component 205.

[0114] The aforementioned movable seat 204 along the first direction ( Figure 1 The X-axis direction can be slidably mounted on the mounting base 2 in various ways. In one possible implementation, see [link to relevant documentation]. Figure 1 The movable base 204 is provided with a guide rod 2041 extending along a first direction. The guide rod 2041 is slidably inserted into the mounting base 2 along the first direction, so that the movable base 204 can move along the first direction ( Figure 1 The purpose of the mounting base 2 is to allow it to slide in the X-axis direction.

[0115] The number of guide rods 2041 can be one, two, or three, etc., and this embodiment does not limit this.

[0116] One embodiment of this application also provides a battery cell winding machine 300, see [link to relevant documentation] Figure 3 The battery cell winding machine 300 includes a cutting mechanism 200.

[0117] The structure of the cutting mechanism 200 can be the same as that of any of the cutting mechanisms 200 described in the above embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description of the cutting mechanism 200 in the above embodiments. This embodiment will not repeat the description here.

[0118] In this embodiment, since the cutting mechanism 200 can avoid interference between the smoothing part 4 and the cutter 203, the normal operation of the battery cell winding machine 300 can be well guaranteed when the battery cell winding machine 300 includes the cutting mechanism 200.

[0119] In some embodiments, see Figure 1 and Figure 3The battery cell winding machine 300 also includes a winding needle 301, and a first driving member 1 for driving the mounting base 2 along a first direction ( Figure 1 The smoothing member 4 moves radially towards or away from the needle coil 301 along the X-axis direction to drive the smoothing member 4 along the second direction (X-axis direction). Figure 1 The smoothing part 4 moves along the axial direction of the coil needle 301 (in the Y-axis direction).

[0120] Since the first driving element 1 can drive the mounting base 2 along the first direction ( Figure 1 The first driving element 1 drives the mounting base 2 to move along the first direction (X-axis direction). Figure 1 When the smoothing member 4 moves along the radial direction of the winding needle 301 (X-axis direction), it can drive the smoothing member 4 to move closer to the winding needle 301, so that the smoothing member 4 abuts against the electrode tab wound on the electrode plate on the winding needle 301, thereby achieving the purpose of smoothing the electrode tab. When the second driving member 3 drives the smoothing member 4 along the second direction (X-axis direction), it can drive the smoothing member 4 to move closer to the winding needle 301 (X-axis direction). Figure 1 When the smoothing member 4 moves along the axial direction of the needle coil 301 (in the Y-axis direction), it can move beyond the cutter 203, causing the smoothing member 4 to be misaligned with the cutter 203, thereby avoiding interference between the smoothing member 4 and the cutter 203.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
