[0001] The present application relates to the field of battery manufacturing, and in particular to a cutting device, a wiping device and a battery production line. Background Art

[0002] Energy conservation and emission reduction are the key to the sustainable development of the automobile industry. Electric vehicles have become an important part of the sustainable development of the automobile industry due to their advantages in energy conservation and environmental protection. For electric vehicles, battery technology is an important factor in their development.

[0003] During the manufacturing process of the battery, it is necessary to use cut wiping paper to wipe the surface of the battery cell. The wiping paper needs to be cut when used, but there is a risk that the wiping paper is still connected after being cut. Utility Model Content

[0004] In view of the above problems, the embodiments of the present application provide a cutting device, a wiping device and a battery production line, which can improve the success rate of the wiping paper being cut by a cutter.

[0005] In a first aspect, an embodiment of the present application provides a cutting device including a pair of cutters, a driving mechanism, and an adjusting mechanism. The pair of cutters extend along a first direction. The driving mechanism is configured to drive the pair of cutters to close or open each other along a second direction. The adjusting mechanism is configured to drive one of the pair of cutters to rotate so that the pair of cutters abut along a third direction before the pair of cutters are closed. The rotation axis of one of the pair of cutters is parallel to the first direction, the third direction is the movement direction of the cut material, and the first direction, the second direction, and the third direction are perpendicular to each other.

[0006] In the technical solution of the embodiment of the present application, the adjustment mechanism can drive one of a pair of cutters to rotate, so that before the pair of cutters close, the pair of cutters abut against each other in the movement direction of the material, so that the shearing force applied to the material by the pair of cutters is more concentrated, making it easier to cut off the material, thereby reducing the risk of the material remaining connected after being cut.

[0007] In some embodiments, the pair of cutters are respectively a first cutter and a second cutter arranged in sequence along a third direction. The driving mechanism is configured to drive the second cutter to reciprocate along the second direction. The adjusting mechanism is configured to drive the first cutter to rotate around the rotation axis to abut against the second cutter.

[0008] In the above technical solution, the second cutter moves back and forth along the second direction to close or open the pair of cutters; the first cutter rotates around the rotation axis so that the pair of cutters abut against each other along the third direction. The driving mechanism and the adjusting mechanism act on the two cutters in the pair of cutters respectively, which can simplify the structure of the cutting device and facilitate the design and processing of the cutting device.

[0009] In some embodiments, along the height direction of the first cutter, the first cutter has a first side, and the first side is provided with a first groove for the cut material to pass through. The first groove is formed by the first side being recessed away from the second cutter, and the blade of the first cutter is located at the bottom of the first groove. The height direction of the first cutter is perpendicular to the first direction and forms an angle with the second direction.

[0010] In the above technical solution, the first groove is formed by the first side being recessed away from the second cutter, and the blade of the first cutter is located at the bottom of the first groove. The material passes through the first groove, and is located between the blades of the second cutter and the first cutter along the second direction. The second cutter approaches the bottom of the first groove along the second direction to cooperate with the blade of the first cutter to cut off the material. The structure is simple and easy to implement.

[0011] In some embodiments, the first cutter has a second side facing the second cutter. The blade of the second cutter is located on one side of the second cutter in the first direction. The adjustment mechanism is configured to drive the first cutter to rotate around the rotation axis so that the second side abuts against the blade of the second cutter.

[0012] In the above technical solution, under the drive of the adjustment mechanism, the second side abuts against the blade of the second cutter, so that when the second cutter approaches the bottom of the first groove along the second direction, the adjustment mechanism can drive the second side to abut against the first cutter.

[0013] In some embodiments, the cutting device further comprises a base, the first cutter is rotatably arranged on the base, the driving mechanism is arranged on the base, the adjusting mechanism is arranged on the base, along the third direction, the first cutter is located between a part of the base and the second cutter, and the adjusting mechanism is located between a part of the base and the first cutter.

[0014] In the above technical solution, the first cutter, the driving mechanism and the adjusting mechanism are arranged on the base, thereby increasing the integration of the cutting device and facilitating the installation of the cutting device.

[0015] In some embodiments, along the third direction, the base has a third side facing the first cutter, and the third side has a receiving portion, and the receiving portion is configured to receive a portion of the adjustment mechanism.

[0016] In the above technical solution, the third side has a receiving portion for receiving part of the adjusting mechanism, thereby reducing the size of the base and the adjusting mechanism in the third direction, and further reducing the size of the cutting device in the third direction, thereby reducing the installation space required for the cutting device.

[0017] In some embodiments, the adjustment mechanism includes an elastic member, which is used to provide elastic force to drive the first cutter to rotate around the rotation axis so as to abut against the second cutter.

[0018] In the above technical solution, the first cutter is driven to rotate around the rotation axis by the elastic member to abut against the second cutter, so that the shearing force applied to the material by the pair of cutters is more concentrated, making it easier to cut the material. The structure is simple and easy to implement.

[0019] In some embodiments, the elastic member is an elastic sheet, and a thickness direction of the elastic sheet is parallel to the third direction.

[0020] In the above technical solution, the elastic member is an elastic sheet, and the thickness direction of the elastic sheet is parallel to the third direction, thereby reducing the size of the adjustment mechanism in the third direction, and then reducing the size of the cutting device in the third direction, thereby reducing the installation space required for the cutting device.

[0021] In some embodiments, the elastic member includes a first portion and a second portion, the first portion is connected to the base. The adjustment mechanism also includes a first abutment member, one end of the first abutment member is connected to the second portion. Along the third direction, there is a gap between the second portion and the base, and the other end of the first abutment member abuts against the first cutter.

[0022] In the above technical solution, there is a gap between the second part and the base along the third direction to provide space for the second part to deform elastically. The elastic force provided by the second part enables the first abutment member to drive the first cutter to rotate around the rotation axis to abut against the second cutter, so that the shearing force applied to the material by the pair of cutters is more concentrated, making it easier to cut the material, and the structure is simple and easy to implement.

[0023] In some embodiments, two second parts are provided, and the two second parts are respectively provided at two ends of the first part in the first direction; two first abutting members are provided, and one end of the two first abutting members is respectively connected to the two second parts.

[0024] In the above technical solution, there are two second parts and two first abutting parts, and the two second parts are respectively arranged at both ends of the first part in the first direction, so that the elastic force of the elastic part is more evenly transmitted to the first cutter, thereby making the first cutter rotate more smoothly.

[0025] In some embodiments, the base includes an end wall and two side walls. The thickness direction of the end wall is parallel to the third direction. The two side walls extend from two ends of the end wall in the first direction in a direction close to the second cutter. The two ends of the first cutter in the first direction are rotatably mounted on the two side walls.

[0026] In the above technical solution, the base includes an end wall and two side walls, and the first cutter is rotatably mounted on the two side walls at both ends in the first direction, which can simplify the structure of the device and facilitate the design and processing of the cutting device.

[0027] In some embodiments, a material passage hole for the cut material to pass through is opened on the end wall.

[0028] In the above technical solution, the material passes through the feed hole and the first groove in sequence along the third direction, so that along the second direction, the material is located between the blades of the second cutter and the first cutter. The second cutter approaches the bottom of the first groove along the second direction to cooperate with the blade of the first cutter to cut off the material. The structure is simple and easy to implement.

[0029] In some embodiments, on the end wall, the orthographic projection of the rotation axis, the material passing hole and the orthographic projection of the adjustment mechanism are arranged in sequence along the second direction.

[0030] In the above technical solution, the orthographic projection of the rotation axis, the feed hole and the orthographic projection of the adjustment mechanism are arranged in sequence along the second direction, and the feed hole is located between the adjustment mechanism and the rotation axis, so that the first groove is located between the adjustment mechanism and the rotation axis, so that the distance between the adjustment mechanism and the rotation axis is greater than the distance between the blade of the first cutter and the rotation axis, which facilitates the adjustment mechanism to drive the first cutter to rotate around the rotation axis.

[0031] In some embodiments, the cutting device further comprises a limit assembly, which is arranged on the driving mechanism. The second cutter comprises a base and a first body connected to the base, and the base is arranged on the driving mechanism. Along the third direction, the base has a fourth side away from the first cutter, and the limit assembly abuts against the fourth side.

[0032] In the above technical solution, along the third direction, the limiting assembly abuts against the fourth side of the base, so that the limiting assembly performs structural limiting on the base, thereby reducing the risk of the second cutter moving away from the first cutter along the third direction during the cutting process.

[0033] In some embodiments, the limit assembly includes a base and a second abutment. The base is disposed on the driving mechanism and is located on a side of the base away from the first cutter. Along the third direction, the base has a fifth side away from the base. The fifth side is provided with a first threaded hole penetrating the base. The second abutment is threadedly engaged with the first threaded hole, and one end of the second abutment passes through the first threaded hole and abuts against the fourth side.

[0034] In the above technical solution, after the second abutment passes through the first threaded hole, it limits its own movement with the first threaded hole in the third direction through threaded cooperation, and one end of the second abutment abuts against the fourth side to limit the second cutter from moving away from the first cutter along the third direction, so that the shearing force applied to the material by the pair of cutters is more concentrated, making it easier to cut off the material, thereby reducing the risk of the material remaining connected after being cut.

[0035] In some embodiments, the base includes a second body and two limiting portions. The second body is disposed on the driving mechanism and is located on a side of the base away from the first cutter. The two limiting portions extend from two ends of the second body in the first direction in a direction close to the first cutter. Along the first direction, the base is located between the two limiting portions.

[0036] In the above technical solution, along the first direction, the second cutter is located between the two limiting parts, so that the two limiting parts form a structural limit for the base, thereby reducing the risk of the second cutter moving along the first direction relative to the driving mechanism during the cutting process.

[0037] In a second aspect, an embodiment of the present application provides a wiping device for wiping a liquid injection port of a battery cell, the wiping device comprising a cutting device provided in any one embodiment of the first aspect, the cutting device being used for cutting wiping paper.

[0038] In the above technical solution, since the wiping device has the cutting device in the embodiment of the first aspect, the wiping device also has the beneficial effects in the embodiment of the first aspect. Specifically, the adjustment mechanism of the cutting device in the wiping device can drive one of the pair of cutters to rotate, so that before the pair of cutters are closed, the pair of cutters abut against each other in the moving direction of the material, so that the shearing force applied to the material by the pair of cutters is more concentrated, making it easier to cut off the material, thereby reducing the risk of the material being still connected after being cut.

[0039] At the same time, the adjustment mechanism of the cutting device in the wiping device can drive one of the pair of cutters to rotate, so that before the pair of cutters are closed, the pair of cutters abut in the direction of material movement, so that the distance between the blades of the pair of cutters along the third direction is reduced, thereby reducing the deformation of the material, which is conducive to improving the flatness of the incision, reducing the risk of burrs on the incision, and reducing the risk of debris when the wiping paper is cut. Thus, the cleanliness of the wiping device is improved.

[0040] In a third aspect, an embodiment of the present application provides a battery production line, characterized in that it includes the wiping device provided in the embodiment of the second aspect.

[0041] In the above technical solution, since the battery production line has the wiping device in the second embodiment, the battery production line also has the beneficial effects in the second embodiment. Specifically, the cutting device of the wiping device in the battery production line can reduce the risk of debris generated when the wiping paper is cut, thereby improving the cleanliness of the battery production line.

[0058] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0059] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as those commonly understood by technicians in the technical field of this application; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned drawings and any variations thereof are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary and secondary relationship.

[0060] Reference to "embodiment" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

[0061] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "attached" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0062] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the associated objects before and after are in an "or" relationship.

[0063] In the embodiments of the present application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary descriptions and should not constitute any limitation to the present application.

[0064] The term "plurality" used in the present application refers to two or more (including two).

[0065] In the embodiment of the present application, the battery cell may be a secondary battery. A secondary battery refers to a battery cell that can be continuously used by activating active materials by charging after the battery cell is discharged.

[0066] Battery cells include, but are not limited to, lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-hydrogen batteries, nickel-cadmium batteries, lead-acid batteries, and the like.

[0067] A battery cell may include a case and an electrode assembly.

[0068] A battery cell generally includes an electrode assembly. The electrode assembly includes a positive electrode, a negative electrode, and a separator. During the charge and discharge process of the battery cell, active ions (such as lithium ions) are embedded and removed between the positive electrode and the negative electrode. The separator is set between the positive electrode and the negative electrode to reduce the risk of short circuit between the positive and negative electrodes, while allowing active ions to pass through.

[0069] The case is a component for accommodating an electrode assembly, an electrolyte, and other components.

[0070] The electrolyte conducts ions between the positive and negative electrodes and can be in liquid or gel form.

[0071] The shell is generally provided with an injection hole for injecting electrolyte into the shell. After the injection is completed, it is generally necessary to wipe the surrounding side of the injection hole with a wiping paper. Since the wiping paper is generally in a roll shape, when the wiping paper is used, it needs to be cut by a cutting device to make the wiping paper in a size that is easy to clamp and reduce the waste of wiping paper.

[0072] The cutting device includes a pair of cutters arranged opposite to each other, and the pair of cutters cut the wiping paper together. In the related art, the pair of cutters of the cutting device is relatively fixed, and the pair of cutters has a certain gap in the moving direction of the wiping paper. Since the wiping paper has a certain flexibility and the thickness of the wiping paper is relatively thin. When the wiping paper is cut, the pair of cutters used for cutting overlap and the wiping paper is not cut off.

[0073] In view of this, in order to improve the success rate of wiping paper being cut by a cutter, the present application provides a cutting device, which includes an adjustment mechanism, which can drive one of a pair of cutters to rotate, so that before the pair of cutters are closed, the pair of cutters abut against each other in the moving direction of the material, so that the shearing force applied to the material by the pair of cutters is more concentrated, making it easier to cut the material, thereby reducing the risk of the material being still connected after being cut.

[0074] The specific structure of the cutting device is described in detail below in conjunction with the accompanying drawings.

[0075] Please refer to Figure 1 , Figure 1 A schematic diagram of the structure of a cutting device 100 provided in some embodiments of the present application. The present application embodiment provides a cutting device 100 including a pair of cutters 10, a drive mechanism 20 and an adjustment mechanism 40. The pair of cutters 10 extend along a first direction X. The drive mechanism 20 is configured to drive the pair of cutters 10 to close or open each other along a second direction Y. The adjustment mechanism 40 is configured to drive one of the pair of cutters 10 to rotate so that the pair of cutters 10 abut along a third direction Z before the pair of cutters 10 are closed. The rotation axis P of one of the pair of cutters 10 is parallel to the first direction X, the third direction Z is the movement direction of the cut material, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0076] A cutter is a common cutting tool used to cut materials into desired shapes and sizes. Optionally, at least one of the pair of cutters 10 has a blade, so that the shear stress of the pair of cutters 10 is concentrated to facilitate shearing of the material.

[0077] The driving mechanism 20 is used to drive a pair of cutters 10 to close or open relative to each other along the second direction Y. The driving mechanism 20 may be a hydraulic cylinder, a pneumatic cylinder, a motor, or the like.

[0078] “A pair of cutters 10 are closed to each other along the second direction Y” means that the pair of cutters 10 are close to each other in the second direction Y to cut the material. In the embodiment where the pair of cutters 10 both have blades, it can be understood that the blades of the pair of cutters 10 are close to each other in the second direction Y; “A pair of cutters 10 are opened to each other along the second direction Y” means that the pair of cutters 10 are away from each other in the second direction Y and reset to wait for the next cutting of the material. In the embodiment where the pair of cutters 10 both have blades, it can be understood that the blades of the pair of cutters 10 are away from each other in the second direction Y.

[0079] It is understandable that there are many implementations for the pair of cutters 10 to close or open each other along the second direction Y. For example, one of the pair of cutters 10 may move closer to or away from the other along the second direction Y; or the two cutters may move in opposite directions at the same time.

[0080] The adjustment mechanism 40 is used to drive one of the pair of cutters 10 to rotate, so that before the pair of cutters 10 are closed, the pair of cutters 10 abut against each other along the third direction Z. The adjustment mechanism 40 can be an electrical component with linear reciprocating motion, such as a cylinder, an electric push rod, a cam mechanism, a motor, etc., or an elastic part with elastic force.

[0081] “A pair of cutters 10 abut against each other along the third direction Z” means that when the pair of cutters 10 move along the second direction Y, part of one of the pair of cutters 10 abuts against part of the other. It can be understood that in an embodiment where both the pair of cutters 10 have blades, the part used for abutment can be the blade of the non-rotating one of them, and when the pair of cutters 10 are closed along the second direction Y, the blade of one of the pair of cutters 10 abuts against the blade of the other along the third direction Z.

[0082] The first direction X can be the length direction of the pair of cutters 10, or can be parallel to the rotation axis P of one of the pair of cutters 10; the second direction Y is the relative movement direction of the pair of cutters 10 when closing and opening; the third direction Z is the movement direction of the material relative to the pair of cutters 10, and the third direction Z can be inclined relative to the first direction X or perpendicular to the first direction X. In the embodiment where the third direction Z is perpendicular to the first direction X, the mutual closing direction of the pair of cutters 10 is perpendicular to the movement direction of the material, so that the cutting device 100 is convenient for cutting the material and makes the cutting surface smoother.

[0083] In the above technical solution, the adjustment mechanism 40 can drive one of the pair of cutters 10 to rotate, so that before the pair of cutters 10 close, the pair of cutters 10 abut against each other in the movement direction of the material, so that the shearing force applied to the material by the pair of cutters 10 is more concentrated, making it easier to cut the material, thereby reducing the risk of the material remaining connected after being cut.

[0084] Please refer to Figure 1 and Figure 2 , Figure 2 A schematic diagram of the structure of the cutting device 100 provided in some embodiments of the present application in another direction. According to some embodiments of the present application, a pair of cutters 10 are respectively a first cutter 11 and a second cutter 12 arranged in sequence along a third direction Z. The driving mechanism 20 is configured to drive the second cutter 12 to reciprocate along the second direction Y. The adjusting mechanism 40 is configured to drive the first cutter 11 to rotate around the rotation axis P to abut against the second cutter 12.

[0085] It can be understood that the second cutter 12 and the driving mechanism 20 can be connected in an undetachable manner, or the second cutter 12 and the driving mechanism 20 can be connected in a detachable manner, so that the driving mechanism 20 drives the second cutter 12 to move along the second direction Y.

[0086] like Figure 2 As shown, the driving mechanism 20 is configured to drive the second cutter 12 to move along the N1 direction to approach the blade 114 of the first cutter 11, so as to achieve the closure of the first cutter 11 and the second cutter 12; and to drive the second cutter 12 along the N2 direction away from the blade 114 of the first cutter 11 to achieve the opening of the first cutter 11 and the second cutter 12, wherein the N1 direction and the N2 direction are both parallel to the second direction Y, and the N1 direction is opposite to the N2 direction.

[0087] The adjustment mechanism 40 is configured to provide a supporting force to the first cutter 11 when the second cutter 12 moves in the N1 direction, so that when the first cutter 11 cooperates with the second cutter 12 to rotate around the rotation axis in the W1 direction, the blade 121 of the second cutter 12 abuts against the surface of the first cutter 11 facing the second cutter 12 in the third direction Z. When the first cutter 11 and the second cutter 12 are closed, the blade 114 of the first cutter 11 abuts against the blade 121 of the second cutter 12 in the third direction Z to cut the material; when the second cutter 12 moves in the N2 direction, the adjustment mechanism drives the first cutter 11 to rotate and reset in the W2 direction to wait for the next cutting of the material.

[0088] In the above technical solution, the second cutter 12 reciprocates along the N1 direction and the N2 direction to close or open the pair of cutters 10; the first cutter 11 rotates around the rotation axis P along the W1 direction and the W2 direction in coordination with the movement of the first cutter 11, so that the pair of cutters 10 abut along the third direction Z. The driving mechanism 20 and the adjusting mechanism 40 act on the two cutters in the pair of cutters 10 respectively, which can simplify the structure of the cutting device 100 and facilitate the design and processing of the cutting device 100.

[0089] Please refer to Figure 2 and Figure 3 , Figure 3A schematic diagram of the structure of the first cutter 11 provided for some embodiments of the present application. According to some embodiments of the present application, along the height direction Y1 of the first cutter 11, the first cutter 11 has a first side 111, and the first side 111 is provided with a first groove 112 for the cut material to pass through. The first groove 112 is formed by the first side 111 being recessed in a direction away from the second cutter 12, and the blade 114 of the first cutter 11 is located at the bottom of the first groove 112. The height direction Y1 of the first cutter 11 is perpendicular to the first direction X, and forms an angle with the second direction Y.

[0090] It can be understood that the height direction Y1 of the first cutter 11 is perpendicular to the extension direction of the first cutter 11, that is, the first direction X. Since the first cutter 11 rotates around the rotation axis P, the angle between the height direction Y1 of the first cutter 11 and the second direction Y changes with the rotation of the first cutter 11.

[0091] When the pair of cutters 10 are in an open state, the first side 111 is such that the first cutter 11 is close to a surface of the second cutter 12 in the height direction Y1 of the first cutter 11 .

[0092] “The first groove 112 is formed by the first side 111 being recessed in a direction away from the second cutter 12” can be understood as when the pair of cutters 10 are opened, the first side 111 is recessed along the height direction Y1 of the first cutter 11 in a direction away from the second cutter 12 to form the first groove 112.

[0093] like Figure 2 As shown, when the pair of cutters 10 are in an open state, the material passes through the first groove 112 along the third direction Z to be located between the blade 114 of the first cutter 11 and the second cutter 12 in the second direction Y.

[0094] In the above technical solution, the first groove 112 is formed by the first side 111 being recessed in a direction away from the second cutter 12, and the blade 114 of the first cutter 11 is located at the bottom of the first groove 112. The material passes through the first groove 112, and is located between the second cutter 12 and the blade 114 of the first cutter 11 along the second direction Y. The second cutter 12 approaches the bottom of the first groove 112 along the second direction Y to cooperate with the blade 114 of the first cutter 11 to cut off the material. The structure is simple and easy to implement.

[0095] Please refer to Figure 2 and Figure 3 According to some embodiments of the present application, the first cutter 11 has a second side 115 facing the second cutter 12. The blade 121 of the second cutter 12 is located on one side of the second cutter 12 in the first direction X. The adjustment mechanism 40 is configured to drive the first cutter 11 to rotate around the rotation axis P so that the second side 115 and the blade 121 of the second cutter 12 abut against each other.

[0096] The second side 115 is a side of the first cutter 11 for contacting with the blade 121 of the second cutter 12 .

[0097] In the embodiment where the first cutter 11 is located at the bottom of the first groove 112, the blade 114 of the first cutter 11 is located at the junction of the second side 115 and the bottom of the first groove 112. When the blade 121 of the second cutter 12 moves along the N1 direction, the first cutter 11 rotates around the rotation axis P along the W1 direction, and when the first cutter 11 and the second cutter 12 are closed, the blade 114 of the first cutter 11 and the blade 121 of the second cutter 12 abut along the third direction Z.

[0098] In the above technical solution, under the drive of the adjustment mechanism 40, the second side 115 and the blade 121 of the second cutter 12 abut against each other, so that when the second cutter 12 approaches the bottom of the first groove 112 along the second direction Y, the adjustment mechanism 40 can drive the second side 115 to abut against the first cutter 11. This makes the shearing force of the first cutter 11 and the shearing force of the second cutter 12 on the material more concentrated, thereby reducing the risk of the material being still connected after being cut.

[0099] Please refer to Figure 1 and Figure 2 , and please continue to refer to Figure 3 and Figure 4 , Figure 4 A schematic diagram of the structure of a base 30 provided in some embodiments of the present application. According to some embodiments of the present application, the cutting device 100 further includes a base 30, and the first cutter 11 is rotatably disposed on the base 30. The adjustment mechanism 40 is disposed on the base 30. Along the third direction Z, the first cutter 11 is located between a portion of the base 30 and the second cutter 12, and the adjustment mechanism 40 is located between a portion of the base 30 and the first cutter 11.

[0100] The base 30 is used for being fixedly connected to an external frame and for installing the first cutter 11 .

[0101] In some embodiments, a rotating shaft 33 extending along the first direction X is provided on the base 30, and first mounting holes 113 are provided at both ends of the first cutter 11. The rotating shaft 33 is inserted into the first mounting hole 113. The first mounting hole 113 can be rotated relative to the rotating shaft 33 so that the first cutter 11 is rotatably installed on the base 30. It can be understood that the axis of the first mounting hole 113 and the axis of the rotating shaft 33 both coincide with the rotation axis P.

[0102] The adjustment mechanism 40 is located between a portion of the base 30 and the first cutter 11 to drive the first cutter 11 to rotate relative to the base 30 .

[0103] Optionally, the driving mechanism 20 may also be connected to the base 30. For example, the driving mechanism 20 may be connected to the base 30 by welding, or the driving mechanism 20 may also be connected to the base 30 in a detachable manner.

[0104] In some embodiments, a third mounting hole 313 is provided on one side of the base 30 facing the driving mechanism 20, and the driving mechanism 20 has a second mounting hole 21 penetrating the driving mechanism 20 along the third direction Z, and a bolt passes through the second mounting hole 21 and is threadedly engaged with the third mounting hole 313, so that the driving mechanism 20 and the base 30 are detachably connected, thereby facilitating the disassembly and maintenance of the driving mechanism 20.

[0105] In the above technical solution, the first cutter 11 , the adjustment mechanism 40 and the driving mechanism 20 are arranged on the base 30 , thereby increasing the integration of the cutting device 100 , thereby facilitating the installation of the cutting device 100 .

[0106] Please refer to Figure 1 and Figure 2 , and please continue to refer to Figure 3 and Figure 4 According to some embodiments of the present application, along the third direction Z, the base 30 has a third side 314 facing the first cutter 11 , and the third side 314 has a receiving portion 311 , which is configured to receive a portion of the adjustment mechanism 40 .

[0107] For the surface of the base 30 facing the first cutter 11 along the third direction Z, illustratively, the projection of the first cutter 11 along the third direction Z completely falls within the third side 314 .

[0108] The accommodation portion 311 is formed by a portion of the third side 314 being recessed away from the first cutter 11 along the third direction Z, and a portion of the adjustment mechanism 40 is located in the accommodation portion 311 .

[0109] In the above technical solution, the third side 314 has a receiving portion 311 for receiving part of the adjusting mechanism 40, thereby reducing the size of the base 30 and the adjusting mechanism 40 in the third direction Z, and further reducing the size of the cutting device 100 in the third direction Z, thereby reducing the installation space required for the cutting device 100.

[0110] Please refer to Figure 2 , and please continue to refer to Figure 4-Figure 6 , Figure 5 This is a schematic diagram of the structure of the base 30 and the adjustment mechanism 40 provided in some embodiments of the present application. Figure 6 for Figure 2 According to some embodiments of the present application, the adjustment mechanism 40 includes an elastic member 41. The elastic member 41 is used to provide elastic force to drive the first cutter 11 to rotate around the rotation axis P so as to abut against the second cutter 12.

[0111] The elastic member 41 may be a spring or other elastic elements.

[0112] Reference Figure 2 , Figure 5 and Figure 6 The elastic member 41 can be squeezed by the first cutter 11 rotating in the W1 direction before the second cutter 12 moves in the N1 direction to close the first cutter 11 and the second cutter 12, so as to produce elastic deformation and accumulate elastic force, and at the same time, when the first cutter 11 and the second cutter 12 are closed, the blade 114 of the first cutter 11 abuts against the blade 121 of the second cutter 12. When the second cutter 12 moves in the N2 direction, the elastic force is released to make the first cutter 11 rotate and reset in the W2 direction to wait for the next cutting of the material.

[0113] In the embodiment where the third side 314 has the receiving portion 311 , at least a portion of the elastic member 41 is received in the receiving portion 311 .

[0114] In the above technical solution, the first cutter 11 is driven to rotate around the rotation axis P by the elastic member 41 to abut against the second cutter 12 in the third direction Z, so that the shearing force applied to the material by the pair of cutters 10 is more concentrated, making it easier to cut the material. The structure is simple and easy to implement.

[0115] Please refer to Figure 2 , and please continue to refer to Figure 4-Figure 6 According to some embodiments of the present application, the elastic member 41 is an elastic sheet, and the thickness direction of the elastic sheet is parallel to the third direction Z.

[0116] The elastic sheet can be made of high manganese steel, which is an alloy steel material with high strength, high hardness and good wear resistance, and is mainly composed of iron (Fe), manganese (Mn) and a small amount of carbon (C) and other alloy elements.

[0117] In the embodiment where the third side 314 has the receiving portion 311 , the entire elastic sheet is received in the receiving portion 311 .

[0118] In the above technical solution, the elastic member 41 is an elastic sheet, and the thickness direction of the elastic sheet is parallel to the third direction Z, thereby reducing the size of the adjustment mechanism 40 in the third direction Z, and then reducing the size of the cutting device 100 in the third direction Z, thereby reducing the installation space required for the cutting device 100.

[0119] Please refer to Figure 2 , and please continue to refer to Figure 4-Figure 6According to some embodiments of the present application, the elastic member 41 includes a first portion 411 and a second portion 412, and the first portion 411 is connected to the base 30. The adjustment mechanism 40 also includes a first abutting member 42, and one end of the first abutting member 42 is connected to the second portion 412. Along the third direction Z, there is a gap between the second portion 412 and the base 30, and the other end of the first abutting member 42 abuts against the first cutter 11.

[0120] The first portion 411 is a portion of the elastic member 41 used for connecting with the base 30 .

[0121] Reference Figure 4 and Figure 5 In the embodiment where the third side 314 has a receiving portion 311 and the elastic member 41 is an elastic sheet, the bottom of the receiving portion 311 has a convex portion 311A ​​protruding toward the first cutter 11 along the third direction Z, and a fourth mounting hole 311B is formed on the convex portion 311A. A bolt (not shown) penetrates the elastic member 41 along the thickness direction of the elastic member 41 (i.e., the third direction Z) and is threadedly engaged with the fourth mounting hole 311B, so that the elastic member 41 is detachably connected to the base 30.

[0122] The second portion 412 is a portion of the elastic member 41 that is used for elastic deformation.

[0123] “Along the third direction Z, there is a gap between the second portion 412 and the base 30,” refer to Figure 2 and Figure 6 In the embodiment where the third side 314 has the receiving portion 311 and the elastic member 41 is an elastic sheet, it can be understood that there is a gap between the second portion 412 and the bottom of the receiving portion 311 along the third direction Z to provide space for the second portion 412 to deform elastically.

[0124] The first abutting member 42 and the second portion 412 may be connected in a non-detachable manner such as welding or riveting, or the first abutting member 42 and the second portion 412 may be connected in a detachable manner such as threaded connection.

[0125] In the above technical solution, there is a gap between the second part 412 and the base 30 along the third direction Z to provide space for elastic deformation of the second part 412. The elastic force provided by the second part 412 allows the first abutting member 42 to drive the first cutter 11 to rotate around the rotation axis P to abut against the second cutter 12, so that the shearing force applied to the material by the pair of cutters 10 is more concentrated, making it easier to cut the material, and the structure is simple and easy to implement.

[0126] Please refer to Figure 4 and Figure 5According to some embodiments of the present application, two second parts 412 are provided, and the two second parts 412 are respectively provided at the two ends of the first part 411 in the first direction X, and two first abutment members 42 are provided, and one end of the two first abutment members 42 is respectively connected to the two second parts 412.

[0127] In the above technical solution, there are two second parts 412 and two first abutment members 42, and the two second parts 412 are respectively arranged at the two ends of the first part 411 in the first direction X, so that the elastic force of the elastic member 41 is more evenly transmitted to the first cutter 11, thereby making the first cutter 11 rotate more smoothly.

[0128] Please refer to Figure 1 , and please refer to Figure 4 and Figure 5 According to some embodiments of the present application, the base 30 includes an end wall 31 and two side walls 32. The thickness direction of the end wall 31 is parallel to the third direction Z. The two side walls 32 extend from both ends of the end wall 31 in the first direction X in a direction close to the second cutter 12. Both ends of the first cutter 11 in the first direction X are rotatably mounted on the two side walls 32.

[0129] The end wall 31 is a component in the base 30 for connecting the two side walls 32. In an embodiment in which the base 30 has a third side 314 and a receiving portion 311, the third side 314 and the receiving portion 311 are located on the end wall 31. In an embodiment in which the drive mechanism 20 is installed on the base 30, the drive mechanism 20 is installed on the end wall 31.

[0130] The side wall 32 is a component in the base 30 for rotatably mounting the first cutter 11 . In an embodiment in which a rotating shaft 33 is disposed on the base 30 , the rotating shaft 33 is disposed on the side wall 32 .

[0131] It can be understood that the end wall 31 and the two side walls 32 can be non-detachably connected by welding or integral molding, or the end wall 31 and the two side walls 32 can be detachably connected by bolt connection.

[0132] In the embodiment where the end wall 31 and the two side walls 32 are detachably connected by bolt connection, the first cutter 11 can be quickly removed by removing the next side wall 32, so that the cutting device 100 can be quickly inspected.

[0133] In the above technical solution, the base 30 includes an end wall 31 and two side walls 32, and the first cutter 11 is rotatably mounted on the two side walls 32 at both ends in the first direction X, which can simplify the structure of the device and facilitate the design and processing of the cutting device 100.

[0134] Please refer to Figure 1 and Figure 2, and please refer to Figure 4 and Figure 5 According to some embodiments of the present application, a material passage hole 312 for the cut material to pass through is opened on the end wall 31.

[0135] The material passing hole 312 is a through hole penetrating the end wall 31 for allowing materials to pass through. Exemplarily, the end wall 31 has a material passing hole 312 penetrating the end wall 31 along the third direction Z.

[0136] In the embodiment where the end wall 31 has a third side 314 , a material passing hole 312 penetrating the end wall 31 along the third direction Z is formed on the third side 314 .

[0137] It can be understood that at least a portion of the orthographic projection of the first groove 112 on the third side 314 overlaps with the feed hole 312 .

[0138] The cross section of the material passage hole 312 should be adapted to the cross section of the material. For example, the cross section of the material passage hole 312 may be circular, rectangular, or the like.

[0139] In the above technical solution, the feed hole 312 corresponds to the first groove 112, and the material passes through the feed hole 312 and the first groove 112 in sequence along the third direction Z, so that along the second direction Y, the material is located between the second cutter 12 and the blade 114 of the first cutter 11. The second cutter 12 approaches the bottom of the first groove 112 along the second direction Y to cooperate with the blade 114 of the first cutter 11 to cut off the material. The structure is simple and easy to implement.

[0140] Please refer to Figure 4 and Figure 5 According to some embodiments of the present application, on the end wall 31 , the orthographic projection of the rotation axis P, the feed hole 312 , and the orthographic projection of the adjustment mechanism 40 are arranged in sequence along the second direction Y.

[0141] In the embodiment where the end wall 31 has a third side 314 , on the third side 314 , the orthographic projection of the rotation axis P, the material passing hole 312 and the accommodating cavity are arranged in sequence along the second direction Y.

[0142] It can be understood that the rotation axis P can be close to the first side 111, so that most of the first cutters 11 are close to the end wall 31 along the W1 direction or away from the end wall 31 along the W2 direction when rotating around the rotation axis P. This reduces the risk of interference between the portion of the first cutter 11 located between the rotation axis P and the first side 111 and the base 30.

[0143] The orthographic projection of the rotation axis P, the feed hole 312 and the orthographic projection of the adjustment mechanism 40 are arranged in sequence along the second direction Y, and the feed hole 312 is located between the adjustment mechanism 40 and the rotation axis P, so that the first groove 112 is located between the adjustment mechanism 40 and the rotation axis P. The distance between the adjustment mechanism 40 and the rotation axis P is greater than the distance between the blade 114 of the first cutter 11 and the rotation axis P, so that the adjustment mechanism 40 and the first cutter 11 form a labor-saving lever structure, which makes it easier for the adjustment mechanism 40 to drive the first cutter 11 to rotate around the rotation axis P.

[0144] Please refer to Figure 7 , Figure 7 A schematic diagram of the structure of a driving mechanism 20, a limiting assembly 50 and a second cutter 12 provided in some embodiments of the present application. According to some embodiments of the present application, the cutting device 100 further includes a limiting assembly 50, which is disposed on the driving mechanism 20. The second cutter 12 includes a base 12B and a first body 12A connected to the base 12B, and the base 12B is disposed on the driving mechanism 20. Along the third direction Z, the base 12B has a fourth side 123 facing away from the first cutter 11 (not shown in the figure), and the limiting assembly 50 abuts against the fourth side 123.

[0145] The base 12B is the part of the second cutter 12 connected to the drive mechanism 20. In the embodiment in which the second cutter 12 is detachably connected to the drive mechanism 20, the base 12B may have a first waist-shaped hole 122 that penetrates the base 12B along the second direction Y. The drive mechanism 20 is provided with a second threaded hole (not shown in the figure) corresponding to the first waist-shaped hole 122. The bolt passes through the first waist-shaped hole 122 and is threadedly matched with the second threaded hole (not shown in the figure) to limit the movement of the base 12B relative to the drive mechanism 20. It can be understood that the first waist-shaped hole 122 extends along the third direction Z, so that when the bolt (not shown in the figure) does not limit the movement of the base 12B relative to the drive mechanism 20, the base 12B can move along the third direction Z, so that the blade 121 of the second cutter 12 abuts against the first cutter (not shown in the figure).

[0146] The first body 12A is a portion of the second cutter 12 for cutting materials. Exemplarily, the blade 121 of the second cutter 12 is located on the first body 12A.

[0147] The first body 12A and the base 12B may be connected to each other by integral molding, or the first body 12A and the base 12B may be connected to each other by post-welding.

[0148] The fourth side 123 is a surface of the base 12B along the third direction Z facing away from the first cutter (not shown in the figure).

[0149] In the embodiment where the driving mechanism 20 is a cylinder, the limiting assembly 50 and the base 12B are both installed at the telescopic end of the cylinder.

[0150] When cutting materials, the second cutter 12 is subjected to a reaction force provided by the materials along the third direction Z, so that the second cutter 12 tends to move away from the first cutter (not shown in the figure) along the third direction Z. Along the third direction Z, the limiting assembly 50 abuts against the fourth side 123 of the base 12B, so that the limiting assembly 50 performs structural positioning on the base 12B. This reduces the risk of the second cutter 12 moving away from the first cutter (not shown in the figure) along the third direction Z during the cutting process.

[0151] Please refer to Figure 7 and Figure 8 , Figure 8 A cross-sectional view of a driving mechanism 20, a limiting assembly 50, and a second cutter 12 provided for some embodiments of the present application. According to some embodiments of the present application, the limiting assembly 50 includes a base 51 and a second abutment 52. The base 51 is disposed on the driving mechanism 20 and is located on a side of the base 12B away from the first cutter 11. Along the third direction Z, the base 51 has a fifth side 513 away from the base 12B. The fifth side 513 is provided with a first threaded hole (not shown in the figure) penetrating the base 51. The second abutment 52 is threadedly matched with the first threaded hole (not shown in the figure), and one end of the second abutment 52 passes through the first threaded hole and abuts against the fourth side 123.

[0152] The base 51 is a portion of the limiting assembly 50 used for connecting with the driving mechanism 20. Exemplarily, the base 30 is detachably connected to the driving mechanism 20 by bolt connection.

[0153] The fifth side 513 is the surface of the base 51 away from the base 12B along the third direction Z; the first threaded hole (not shown in the figure) is a threaded hole on the fifth side 513 that passes through the base 51. Exemplarily, the first threaded hole (not shown in the figure) passes through the base 51 along the third direction Z.

[0154] It can be understood that the outer peripheral side of the second abutment member 52 has an external thread that matches the first threaded hole (not shown in the figure). Exemplarily, the second abutment member 52 can be a bolt.

[0155] In the embodiment where the first waist-shaped hole 122 is provided on the base 12B, the second abutment member 52 is threadedly matched with the first threaded hole (not shown in the figure), and one end of the second abutment member 52 passes through the first threaded hole and abuts against the fourth side 123, so as to limit the base 12B from moving away from the first cutter 11 along the third direction Z relative to the driving mechanism 20.

[0156] In the above technical solution, after the second abutment member 52 passes through the first threaded hole (not shown in the figure), it limits its own movement with the first threaded hole (not shown in the figure) in the third direction Z through threaded cooperation, and one end of the second abutment member 52 abuts against the fourth side 123 to limit the second cutter 12 from moving away from the first cutter 11 along the third direction Z, so that the shearing force applied to the material by the pair of cutters 10 is more concentrated, making it easier to cut the material, thereby reducing the risk of the material being still connected after being cut.

[0157] Please refer to Figure 7 According to some embodiments of the present application, the base 51 includes a second body 511 and two stoppers 512. The second body 511 is disposed on the driving mechanism 20 and is located on a side of the base 12B away from the first cutter 11. The two stoppers 512 extend from both ends of the second body 511 in the first direction X in a direction close to the first cutter 11. Along the first direction X, the base 12B is located between the two stoppers 512.

[0158] The second body 511 is a portion of the base 51 connected to the driving mechanism 20 . Exemplarily, the second body 511 is detachably connected to the driving mechanism 20 via bolts.

[0159] The limiting portion 512 is a portion of the base 51 connected to one end of the second body 511 in the first direction X.

[0160] The second body 511 and the two limiting portions 512 may be connected by integral molding, or the second body 511 and the two limiting portions 512 may be connected by welding.

[0161] In the above technical solution, the second cutter 12 is located between the two limiting portions 512 along the first direction X. The two limiting portions 512 form a structural limit for the base 12B, thereby reducing the risk of the second cutter 12 moving relative to the driving mechanism 20 along the first direction X during the cutting process.

[0162] An embodiment of the present application provides a wiping device, comprising a cutting device 100 provided in any one of the above embodiments, and the cutting device 100 is used for cutting wiping paper.

Specifically, the adjusting mechanism 40 of the cutting device 100 in the wiping device can drive one of the pair of cutters 10 to rotate, so that before the pair of cutters 10 close, the pair of cutters 10 abut against each other in the movement direction of the material, so that the shearing forces applied to the material by the pair of cutters 10 are more concentrated, and the material is easier to cut, thereby reducing the risk of the material being still connected after being cut.

[0164] At the same time, the adjustment mechanism 40 of the cutting device 100 in the wiping device can drive one of the pair of cutters 10 to rotate, so that before the pair of cutters 10 are closed, the pair of cutters 10 abut against each other in the moving direction of the material, so that the distance between the blades of the pair of cutters 10 along the third direction Z is reduced, thereby reducing the deformation of the material, which is conducive to improving the flatness of the incision, reducing the risk of burrs on the incision, and reducing the risk of debris when the wiping paper is cut. Thereby improving the cleanliness of the wiping device.

[0165] An embodiment of the present application provides a battery production line, comprising the wiping device provided by any one of the above embodiments.

[0167] According to some embodiments of the present application, a cutting device 100 is provided. Figure 1-Figure 8 .

[0168] The cutting device 100 includes a pair of cutters 10 , a driving mechanism 20 , a base 30 , an adjusting mechanism 40 and a limiting assembly 50 .

[0169] The pair of cutters 10 are respectively a first cutter 11 and a second cutter 12 which are arranged in sequence along the third direction Z. The first cutter 11 and the second cutter 12 both extend along the first direction X.

[0170] The first direction X is the length direction of the pair of cutters 10, and is also parallel to the rotation axis P of one of the pair of cutters 10; the second direction Y is the relative movement direction of the pair of cutters 10 when closing and opening; the third direction Z is the movement direction of the material relative to the pair of cutters 10, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0171] The base 30 includes an end wall 31 and two side walls 32, and the thickness direction of the end wall 31 is parallel to the third direction Z. The two side walls 32 extend from both ends of the end wall 31 in the first direction X in a direction close to the second cutter 12. The first cutter 11 is rotatably mounted on the two side walls 32 at both ends in the first direction X.

[0172] The end wall 31 has a third side 314 facing the first cutter 11 along the third direction Z, and the third side 314 has a receiving portion 311 .

[0173] The adjustment mechanism 40 includes an elastic member 41 and a first abutment member 42 , wherein the elastic member 41 is an elastic sheet and has a first portion 411 and a second portion 412 .

The height direction Y1 of the first cutter 11 is perpendicular to the first direction X, and forms an angle with the second direction Y.

[0177] The rotation axis P is close to the first side 111 .

[0178] The end wall 31 is provided with a material passing hole 312 penetrating the end wall 31 along the third direction Z. At least a portion of the orthographic projection of the first groove 112 on the third side 314 overlaps with the material passing hole 312 .

[0179] The orthographic projection of the rotation axis P, the material passing hole 312 and the orthographic projection of the adjustment mechanism 40 are arranged in sequence along the second direction Y.

[0180] A third mounting hole 313 is provided on the side of the end wall 31 facing the driving mechanism 20. The driving mechanism 20 has a second mounting hole 21 that penetrates the driving mechanism 20 along the second direction Y. The bolt passes through the second mounting hole 21 and is threadedly engaged with the third mounting hole 313, so that the driving mechanism 20 and the base 30 can be detachably connected.
