Description

Technical Field

[0001] The present application relates to a winding tape slitting device, and in particular to a slitting edge pressing device, slitting equipment and a battery production system. Background Art

[0002] The slitting equipment uses a slitting knife to slit the winding tape into two parts, and winds up the slit winding tape through a winding roller. The current problem is that after the winding tape is slit, the cutting edge of the winding tape is uneven and prone to "flash" (the cutting edge appears to be wavy). Utility Model Content

[0003] In view of the above problems, the present application provides a cutting edge pressing device, a cutting device and a battery production system, which can improve the problem of burrs appearing during cutting by the cutting device.

[0004] In a first aspect, the present application provides a cutting edge pressing device, comprising:

[0005] Mounting seat assembly;

[0006] Two pressing wheel assemblies are respectively connected to the mounting seat assembly, the pressing wheel assembly comprises a pressing wheel, the pressing wheel can rotate relative to the mounting seat assembly around a first direction, and the axes of the pressing wheels of the two pressing wheel assemblies are parallel to each other and are spaced apart along a second direction;

[0007] A passing roller is provided on each side of the two pressing wheel assemblies facing away from each other. The passing roller is rotatably connected to the mounting seat assembly. The passing roller and the pressing wheel are used to clamp the cutting edge of the cutting tape together. The axis of the passing roller is configured to be parallel to the axis of the pressing wheel.

[0008] The first direction is the axial direction of the pressure wheel, and the second direction is perpendicular to the first direction.

[0009] During use, each pressing wheel of the two pressing wheel assemblies and each passing roller jointly clamp the cut edges of the slit winding tape, and can roll the cut edges produced after the cutting tape is cut to make it smoother, thereby making the cut winding tape smoother.

[0010] In some embodiments, the position of the pressure wheel assembly relative to the mounting seat assembly along the first direction is adjustable, and the length of the pressure wheel is smaller than the length of the roller.

[0011] The cutting position of winding belts of different specifications may be different, and the trimming position may also be different. The connection position of the pressure wheel assembly relative to the mounting seat along the first direction is adjustable, which can adapt to the shaping of winding belts of different specifications, thereby improving the use range of the trimming and clamping device.

[0012] In some embodiments, the pressure wheel assembly further comprises:

[0013] A movable component is slidably connected to the mounting seat assembly along a first direction, and the movable component is rotatably connected to a pressure wheel;

[0014] The locking member is used to lock the movable part with the mounting seat assembly, and has an unlocking state that enables the movable part to slide relative to the mounting seat assembly along a first direction, and a locking state that enables the movable part to be fixed relative to the mounting seat assembly.

[0015] The movable part is locked on the mounting seat assembly by the locking piece, and when the pressing wheel and the passing roller shape the cutting edge of the cutting tape, the movable part can be prevented from moving relative to the mounting seat assembly to improve the shaping effect.

[0016] In some embodiments, the mounting seat assembly is provided with a first guide structure extending along a first direction, the movable component is provided with a second guide structure extending along the first direction, the first guide structure and the second guide structure are slidingly connected along the first direction, the movable component is provided with a threaded hole, the locking member is threadedly connected to the threaded hole, and the locking member can abut against the first guide structure.

[0017] Thus, through the rotation of the locking piece, the locking piece can be abutted against the first guide structure to prevent the movable part from moving relative to the mounting seat assembly. When the locking piece is rotated in the opposite direction, the locking piece can no longer abut against the first guide structure, so that the movable part can slide relative to the mounting seat assembly, thereby realizing the unlocking and locking action of the locking piece on the movable part, thereby facilitating the shaping of the cutting edge and the adjustment of the clamping position of the pressing wheel when the pressing wheel is working.

[0018] In some embodiments, the first guide structure includes a guide rail, the second guide structure includes a guide groove, and the threaded hole passes through the inner wall of the guide groove. Thus, by rotating the locking member, the locking member and the guide rail can be abutted, or the locking member and the guide rail can be spaced apart, thereby achieving the fixation of the movable component and the relative sliding of the movable component relative to the first guide structure.

[0019] In some embodiments, the movable component further comprises:

[0020] A wheel seat, rotatably connected with a pressure wheel;

[0021] A driving mounting member is slidably connected to the mounting seat assembly along a first direction;

[0022] The driving mechanism is arranged on the driving mounting component and is drivingly connected to the wheel seat, and is used for driving the wheel seat to move relative to the mounting seat assembly along the second direction.

[0023] The driving mechanism drives the wheel seat to move, so that the wheel seat can clamp the cutting belt together with the roller. Through the setting of the driving mechanism, the cutting belt can have a certain clamping force to improve the shaping effect of the cutting edge.

[0024] In some embodiments, the mount assembly includes:

[0025] Support components;

[0026] The flip member is connected to the two pressing wheel assemblies respectively, and the flip member has a first connection position and a second connection position, the first connection position and the second connection position are arranged at intervals along the first direction, the first connection position is rotatably connected to the support member, and a first rotation axis is formed, the first rotation axis is perpendicular to the axis of the pressing wheel, and the first rotation axis is parallel to the plane where the axes of the two pressing wheels are located, or is located on the plane;

[0027] The clamping member is arranged on the support member, and has a clamping portion, which can move relative to the support member, and has a first moving position for clamping with the flip member, and a second moving position for enabling the flip member to rotate relative to the support member.

[0028] For some relatively thick cutting tapes, no "flash" or smaller "flash" will be generated during cutting, and the shaping can be performed without pressing with a pressure wheel, which can also meet the process requirements. At this time, the clamping member can be moved to the second moving position to flip the pressure wheel at a certain angle, and the cutting tape can be directly wound around the roller. For some thinner cutting tapes, "flash" is easily generated during cutting, and the flipping member needs to be moved to a position opposite to the roller, and the clamping member needs to be moved to the first moving position so that the flipping member is clamped with the support member, and the cutting edge is shaped by the pressure wheel and the roller to meet the cutting requirements of different materials.

[0029] In some embodiments, the second connection position is provided with a first socket, and the support component is provided with a second socket. The depth direction of the first socket and the depth direction of the second socket are respectively parallel to the first rotation axis. The clamping part is passed through the second socket, and the clamping part can move relative to the support component along the axial direction of the second socket and switch positions between the second socket and the first socket.

[0030] Therefore, by moving the clamping piece, the unlocking and locking operations of the flip component can be realized to meet the cutting requirements of different materials.

[0031] In some embodiments, the support member includes a body and a rotating shaft, the body is rotatably connected to the rotating shaft, the axis of the rotating shaft forms a first rotating axis, and the flip member is connected to the rotating shaft. Thus, the rotating shaft can realize the rotatable connection between the flip member and the support.

[0032] In a second aspect, the present application provides a slitting device, comprising the slitting edge pressing device of the first aspect.

[0033] Since the slitting equipment includes all the technical features of the slitting edge pressing device of the first aspect mentioned above, the effects are the same as those mentioned above and will not be repeated here.

[0034] In a third aspect, the present application provides a battery production system, comprising the slitting device of the second aspect, wherein the cutting tape comprises pole pieces.

[0035] Since the battery production system includes all the technical features of the slitting equipment of the second aspect mentioned above, the effects are the same as those mentioned above and will not be repeated here.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0055] The slitting equipment uses a slitting knife to cut the winding tape into two parts, and winds up the cut winding tape through a winding roller. The current problem is that after the winding tape is slit, the cutting edge of the winding tape is uneven, and it is easy to have the phenomenon of "flash" (the cut edge appears to be wavy). For example, in the production process of battery pole pieces, it is necessary to cut the rolled pole pieces and reel in the cut pole pieces. For some relatively thin pole pieces, the phenomenon of "flash" will occur during the cutting process. For the part with larger "flash", it can only be scrapped, resulting in material waste.

[0056] In view of this, the present application provides a cutting edge pressing device. During use, each of the two pressing wheel assemblies and each roller together clamp the cutting edge of the winding belt after slitting, and can roll the cutting edge generated after the cutting belt is cut to make it smoother, thereby making the winding belt smoother after cutting. For example, in the process of manufacturing the pole piece of the battery, the pole piece is smoother after cutting, thereby saving the material of the pole piece.

[0057] The cutting and pressing device of the present application can be used for, but not limited to, cutting and shaping positive electrode sheets or negative electrode sheets of different thicknesses.

[0058] For the convenience of explanation, please refer to the following examples. Figure 1-Figure 4 , a cutting edge pressing device 100 of some embodiments of the present application is taken as an example for description.

[0059] The trimming edge clamping device 100 includes a mounting seat assembly 10, a roller 30 and two pressure wheel assemblies 20. The two pressure wheel assemblies 20 are respectively connected to the mounting seat assembly 10, and the pressure wheel assembly 20 includes a pressure wheel 21. The pressure wheel 21 can rotate relative to the mounting seat assembly 10 around a first direction X. The axes of the pressure wheels 21 of the two pressure wheel assemblies 20 are parallel to each other and are arranged at intervals along a second direction Y. The two pressure wheel assemblies 20 are respectively provided with a roller 30 on one side away from each other. The roller 30 is rotatably connected to the mounting seat assembly 10. The roller 30 and the pressure wheel 21 are used to clamp the trimming edge of the cutting tape together, and the axis of the roller 30 is configured to be parallel to the axis of the pressure wheel 21. Among them, the first direction X is the axis direction of the pressure wheel 21, and the second direction Y is perpendicular to the first direction X.

[0060] Optionally, the outer circumferential surface of the roller 30 and the outer circumferential surface of the pressure wheel 21 can be set with a gap, or can be set close to each other. Exemplarily, the outer circumferential surface of the roller 30 and the outer circumferential surface of the pressure wheel 21 are set close to each other, and the roller 30 and the pressure wheel 21 can be made of elastic material. When the slit cutting tape passes through the roller 30 and the pressure wheel 21, the cutting tape passes through the deformation between the two to shape the cutting tape. The outer circumferential surface of the roller 30 and the outer circumferential surface of the pressure wheel 21 can also be set with a gap, and the gap between the two is smaller than the thickness of the cutting tape, so that when the cutting tape passes through the gap between the two, an extrusion force is generated on the cutting tape to shape the cutting tape. In another example, the gap between the outer circumferential surface of the roller 30 and the outer circumferential surface of the pressure wheel 21 is adjustable so that the extrusion force of the cutting tape can be adjusted according to the shaping effect.

[0061] The axis of the passing roller 30 is configured to be parallel to the axis of the pressing wheel 21, which means that when the passing roller 30 and the pressing wheel 21 are in a state of shaping the cut tape, the axes of the two are parallel to each other.

[0062] The pressing wheel 21 can rotate relative to the mounting seat assembly 10 around the first direction X, which means that the pressing wheel 21 can rotate around its own axis, and the axis direction of the pressing wheel 21 is the same as the first direction X.

[0063] During use, each pressing wheel 21 of the two pressing wheel assemblies 20 and each roller 30 jointly clamp the cut edges of the slit winding tape, and can roll the cut edges produced after cutting the cutting tape to make it smoother, thereby making the cut winding tape smoother.

[0064] In some embodiments, please refer to Figure 1 and Figure 2 The position of the pressing wheel assembly 20 relative to the mounting seat assembly 10 along the first direction X is adjustable, and the length of the pressing wheel 21 is smaller than the length of the roller 30 .

[0065] The position of the pressure wheel assembly 20 relative to the mounting seat assembly 10 along the first direction X can be adjusted. The pressure wheel assembly 20 can be driven by a driving component, and the driving component drives the pressure wheel assembly 20 to move relative to the mounting seat assembly 10 along the first direction X, so that the pressure wheel assembly 20 has different relative positions. The driving component can be a linear driving component such as an electric push rod or a hydraulic push rod. The position of the pressure wheel assembly 20 relative to the mounting seat assembly 10 along the first direction X can also be adjusted. The mounting seat assembly 10 has a plurality of installation positions spaced apart along the first direction X, and the pressure wheel assembly 20 can be installed at different installation positions.

[0066] The length of the pressing wheel 21 refers to the dimensions of both ends of the pressing wheel 21 along its own axial direction.

[0067] The length of the roller 30 refers to the dimensions of both ends of the roller 30 along its own axial direction.

[0068] The cutting positions of winding tapes of different specifications may be different, and the trimming positions may also be different. The connection position of the pressure wheel assembly 20 relative to the mounting seat along the first direction X is adjustable, which can adapt to the shaping of winding tapes of different specifications, thereby improving the use range of the trimming and pressing device 100.

[0069] In some embodiments, please refer to Figure 1-Figure 3 The pressure wheel assembly 20 further includes a movable part 22 and a locking member 23. The movable part 22 is slidably connected to the mounting seat assembly 10 along the first direction X, and the movable part 22 is rotatably connected to the pressure wheel 21. The movable part 22 is locked to the mounting seat assembly 10 through the locking member 23, and has an unlocking state in which the movable part 22 can slide relative to the mounting seat assembly 10 along the first direction X, and a locking state in which the movable part 22 is fixed relative to the mounting seat assembly 10. The first direction X is the same as the axial direction of the pressure wheel 21.

[0070] Exemplarily, the movable component 22 includes a sliding assembly, which is slidably connected to the mounting seat assembly 10 along the first direction X. The movable component 22 also includes a wheel seat 221 , which is connected to the sliding assembly and is rotatably connected to the pressure wheel 21 .

[0071] The locking member 23 includes but is not limited to any one of a screw, a set screw, or a combination of a bolt and a nut.

[0072] Exemplarily, the fastener includes a bolt and a nut. The mounting seat assembly 10 is provided with a long slot hole extending along the first direction X, the sliding assembly is provided with a bolt hole, the end of the bolt passes through the bolt hole and the long slot hole, and is threadedly connected with a nut, and the position of the pressure wheel 21 relative to the mounting seat assembly 10 along the first direction X is adjustable by adjusting the installation position of the fastener in the long slot hole. In other examples, the long slot hole can be replaced with a threaded hole, and the nut and the nut can be replaced with a screw.

[0073] The movable component 22 is locked on the mounting seat assembly 10 by the locking member 23. When the pressure wheel 21 and the roller 30 shape the cutting edge of the cutting tape, the movable component 22 can be prevented from moving relative to the mounting seat assembly 10 to improve the shaping effect.

[0074] In some embodiments, please refer to Figure 1-Figure 3 The mounting seat assembly 10 is provided with a first guide structure 122 extending along the first direction X, and the movable component 22 is provided with a second guide structure 224 extending along the first direction X. The first guide structure 122 and the second guide structure 224 are slidably connected along the first direction X. The movable component 22 is provided with a threaded hole, and the locking member 23 is threadedly connected to the threaded hole, and the end of the locking member 23 can abut against the first guide structure 122.

[0075] The first guide structure 122 includes any one of a guide rail and a guide rod, and the second guide structure 224 includes a guide groove. Alternatively, the first guide structure 122 includes any one of a guide groove and a guide hole, and the second guide structure 224 includes a guide protrusion.

[0076] Exemplarily, the first guide structure 122 may be a guide rail, and the second guide structure 224 may be a guide groove. Specifically, the movable component 22 is provided with a threaded hole, the threaded hole passes through the inner wall of the guide groove, and the locking member 23 is threadedly connected to the threaded hole, so that the end of the locking member 23 can abut against the outer surface of the guide rail to fix and lock the movable component 22. When the end of the locking member 23 does not abut against the outer surface of the guide rail, the movable component 22 can slide relative to the mounting seat assembly 10 along the first direction X.

[0077] Exemplarily, the guide groove can be but not limited to a T-slot or a dovetail groove. For example, the cross section of the guide protrusion is T-shaped, the guide groove is a T-slot, and the T-slot and the guide protrusion are slidably matched.

[0078] For example, the first guide structure 122 is a guide rod, the number of the guide rods is multiple, and the multiple guide rods are parallel to each other and spaced apart. The second guide structure 224 is a plurality of guide holes, each guide hole is penetrated by each guide hole and is slidably connected to the guide hole. The axial direction of the guide hole and the axial direction of the guide rod are respectively the same as the first direction X.

[0079] Thus, through the rotation of the locking piece 23, the locking piece 23 can be abutted against the first guide structure 122 to prevent the movable part 22 from moving relative to the mounting seat assembly 10. When the locking piece 23 is rotated in the opposite direction, the locking piece 23 can no longer abut against the first guide structure 122, so that the movable part 22 can slide relative to the mounting seat assembly 10, thereby realizing the unlocking and locking action of the locking piece 23 on the movable part 22, thereby facilitating the shaping of the cutting edge and the adjustment of the clamping position of the pressing wheel 21 when the pressing wheel 21 is working.

[0080] In some embodiments, please refer to Figure 2 The first guide structure 122 includes a guide rail, the second guide structure 224 includes a guide groove, and the threaded hole passes through the inner wall of the guide groove.

[0081] Optionally, the guide rail and the mounting seat assembly 10 can be integrally formed, and the guide rail can also be connected to the mounting seat assembly 10 by screws.

[0082] Therefore, by rotating the locking member 23 , the locking member 23 and the guide rail can be abutted or spaced apart, thereby fixing the movable component 22 and sliding the movable component 22 relative to the first guide structure 122 .

[0083] In some embodiments, please refer to Figure 2 and Figure 3 The movable part 22 further includes a wheel seat 221, a drive mounting member 222 and a drive mechanism 223. The wheel seat 221 is rotatably connected to the pressure wheel 21. The drive mounting member 222 is slidably connected to the mounting seat assembly 10 along the first direction X. The drive mechanism 223 is disposed on the drive mounting member 222 and is drive-connected to the wheel seat 221, and is used to drive the wheel seat 221 to move relative to the mounting seat assembly 10 along the second direction Y.

[0084] Optionally, the driving mechanism 223 may be, but is not limited to, a linear driving component such as a cylinder or an electric push rod.

[0085] Exemplarily, the driving mounting member 222 includes a slider 2222 and a mounting member 2221. The mounting seat assembly 10 is provided with a guide rail, which serves as the first guide structure 122. The length direction of the guide rail is the same as the first direction X. The slider 2222 is slidably connected to the guide rail along the first direction X (the groove in the slider 2222 that slides with the guide rail is a guide groove). The mounting member 2221 is connected to the slider 2222, and the connection between the mounting member 2221 and the slider 2222 includes but is not limited to screw connection, riveting, welding or integral molding. Optionally, the main body of the driving mechanism 223 is mounted on the mounting member 2221, and the driving end of the driving mechanism 223 is connected to the wheel seat 221, which can be screwed or bolted, etc.; or the driving end of the driving mechanism 223 is connected to the mounting member 2221, which can be screwed or bolted, and the main body of the driving mechanism 223 is mounted on the wheel seat 221.

[0086] The driving mechanism 223 includes but is not limited to linear driving components such as a cylinder or an electric push rod.

[0087] The driving mechanism 223 drives the wheel seat 221 to move, so that the wheel seat 221 can clamp the cutting belt together with the roller 30. Through the setting of the driving mechanism 223, the cutting belt can have a certain clamping force to improve the shaping effect of the cutting edge.

[0088] In some embodiments, please refer to Figure 2-Figure 4 The mounting seat assembly 10 includes a support member 11 and a flip member 12. The flip member 12 is connected to the two pressure wheel assemblies 20 respectively. The flip member 12 has a first connection position and a second connection position. The first connection position and the second connection position are arranged at intervals along the first direction X. The first connection position is rotatably connected to the support member 11 and forms a first rotation axis. The first rotation axis is perpendicular to the axis of the pressure wheel 21. The first rotation axis is parallel to the plane where the axes of the two pressure wheels 21 are located, or is located on the plane. The clamping member 13 is arranged on the support member 11. The clamping member 13 has a clamping portion, which can move relative to the support member 11, and the clamping member 13 has a first moving position clamped with the flip member 12, and a second moving position that can rotate the flip member 12 relative to the support member 11.

[0089] Optionally, the turnover member 12 may be, but is not limited to, a plate-shaped structure.

[0090] The movable connection can be a rotational connection or a plug-in connection.

[0091] For example, Figure 4 The connection between the clamping member 13 and the support member 11 is shown to be a rotational connection. Specifically, optionally, a notch 11222 is provided on one side of the support member 11 along the spacing direction of the two pressing wheels 21, and part of the clamping member 13 is located in the notch 11222 and is rotationally connected to the support member 11. A groove 122 is provided on the surface of the flip member 12 facing the notch 11222, and the clamping member 13 can be rotated into the groove 122 and rotated out of the groove 122 to achieve locking and rotation of the flip member 12. The clamping member 13 can be a plate-like structure.

[0092] Optionally, the flip member 12 includes a flip member 121 and a first guide structure 122, the first guide structure 122 may be a guide rail, and the first guide structure 122 is connected to the flip member 12, and the connection between the two may be conveniently screwed, bolted, or integrally formed.

[0096] Optionally, the clamping member 13 may be a latch, specifically but not limited to a round latch or a square latch.

[0097] Therefore, by moving the clamping piece 13, the unlocking and locking operations of the flipping member 12 can be realized to meet the cutting requirements of different materials.
