Description

Technical Field

[0001] The present application relates to the field of battery production, and in particular to a limiting device, a strapping 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] In the development of battery technology, in addition to improving battery reliability, improving battery production efficiency is also a technical problem that needs to be solved urgently. Utility Model Content

[0004] The embodiments of the present application provide a limiting device, a strapping device and a battery production line, which can improve the production efficiency of batteries.

[0005] In a first aspect, an embodiment of the present application provides a limiting device for limiting the movement of a binding member, wherein the binding member is configured as a ring connected end to end, and the limiting device includes a pair of abutment mechanisms and an adjustment mechanism. The pair of abutment mechanisms are spaced apart along a first direction, and the abutment mechanisms include abutment members, and the abutment member of at least one of the pair of abutment mechanisms is configured to be able to reciprocate along the first direction. The adjustment mechanism is configured to drive the abutment member of at least one of the pair of abutment mechanisms to move along the first direction after the binding member is sleeved on the outside of the abutment members of the pair of abutment mechanisms, so that the abutment members of the pair of abutment mechanisms abut against the inner surfaces of the two ends of the binding member in the first direction, respectively.

[0006] In the technical solution of the embodiment of the present application, a pair of abutment mechanisms and an adjustment mechanism are provided, and the abutment mechanism includes an abutment member. After the bundling piece is sleeved on the outside of the abutment member of the pair of abutment mechanisms, the abutment member of at least one of the pair of abutment mechanisms is driven to move in the first direction through the adjustment mechanism, so that the abutment members in the pair of abutment mechanisms abut against the inner surfaces of the two ends of the bundling piece in the first direction, respectively. Thereby, the movement of the bundling piece in the first direction is limited, and the abutment members in the pair of abutment mechanisms can play a structural guiding role for the bundling piece, thereby reducing the risk of the bundling piece being skewed and the bundling piece damaging the abutment member due to the gap between the bundling piece and the abutment member along the first direction when the bundling piece moves from the limit device to the battery module. Thereby, the maintenance time of the limit device is reduced, thereby improving the production efficiency of the battery.

[0007] In some embodiments, the pair of abutment mechanisms are respectively a first abutment mechanism and a second abutment mechanism. The abutment member of the first abutment mechanism is a first abutment member, and the abutment member of the second abutment mechanism is a second abutment member. The adjustment mechanism includes a first adjustment component, and the first adjustment component is configured to drive the first abutment member to move along a first direction.

[0008] In the above technical solution, the first abutment member moves along the first direction so that the first abutment member and the second abutment member respectively abut against the inner surfaces of the two ends of the binding member in the first direction. The first adjustment component acts on the first abutment member, thereby simplifying the structure of the limiting device and facilitating the design and installation of the limiting device.

[0009] In some embodiments, the first abutment mechanism further comprises a first base. The first abutment member is slidably disposed on the first base along a first direction. The first adjustment assembly is disposed on the first base, and the first adjustment assembly is configured to drive the first abutment member to move relative to the first base.

[0010] In the above technical solution, the first abutment member and the first adjustment assembly are both arranged on the first base, thereby increasing the integration of the first abutment mechanism, thereby facilitating the installation of the first abutment mechanism in the limiting device.

[0011] In some embodiments, the first adjustment component includes a first adjustment member and a second adjustment member. The first adjustment member is disposed on the first base, and the first adjustment member has a first threaded hole that penetrates the first adjustment member along the first direction. Along the first direction, the first abutment member has a first side facing the second abutment member, and the first adjustment member is located between the first side and the second abutment member. The second adjustment member is threadedly engaged with the first threaded hole, and one end of the second adjustment member abuts against the first side. The second adjustment member rotates relative to the first threaded hole to adjust the distance between the first abutment member and the second abutment member along the first direction.

[0012] In the above technical solution, the first adjusting member has a first threaded hole that penetrates the first adjusting member along the first direction, the second adjusting member is threadedly matched with the first threaded hole, and one end of the second adjusting member abuts against the first side of the first abutting member facing the second abutting member along the first direction, so that the second adjusting member can provide a supporting force to the first abutting member in a direction away from the second abutting member. This limits the movement of the first abutting member relative to the first base toward the second abutting member, thereby reducing the risk of a gap between the first abutting member and the binding member along the first direction due to the reaction force provided by the binding member.

[0013] In some embodiments, along the first direction, the first abutment has a first surface away from the second abutment, and the second abutment has a second surface away from the first abutment. The first surface and the second surface are configured to abut against part of the inner surface of both ends of the binding member in the first direction.

[0014] In the above technical solution, the first surface of the first abutment member and the second surface of the second abutment member abut against the inner surface of the bundling member, so that the first abutment member and the second abutment member can be in surface contact with the inner surface of the bundling member in the process of limiting the movement of the bundling member in the first direction, so that the bundling member has a good contact area with the first abutment member and the second abutment member in the process of being limited by the limiting device to move in the first direction and in the process of moving relative to the limiting device along the winding axis of the bundling member. The risk of the bundling member flipping and deformation is reduced.

[0015] In some embodiments, the first abutment member and the second abutment member are both two members spaced apart along the second direction. The first direction, the second direction, and the winding axis of the binding member are perpendicular to each other.

[0016] In the above technical solution, the first abutment member and the second abutment member are two members spaced apart along the second direction, so that after the bundling member is sleeved outside the first abutment member and the second abutment member, there is a gap between the inner surfaces of the bundling member along the second direction to facilitate the insertion of the battery module.

[0017] In some embodiments, along the second direction, the first abutting member has a third surface away from the other first abutting member, and the second abutting member has a fourth surface away from the other second abutting member. The third surfaces of the two first abutting members and the fourth surfaces of the two second abutting members are respectively used to abut against part of the inner surface of both ends of the bundling member in the second direction.

[0018] In the above technical solution, the third surfaces of the two first abutting members respectively abut against the partial inner surfaces of the two ends of the bundling member in the second direction, and the fourth surfaces of the two second abutting members respectively abut against the partial inner surfaces of the two ends of the bundling member in the second direction, so that the first abutting member and the second abutting member are in surface contact with the inner surfaces of the two ends of the bundling member in the second direction, so that the bundling member has a good contact area with the first abutting member and the second abutting member during the process of being restricted by the limiting device to move in the first direction and the second direction and during the process of moving relative to the limiting device along the winding axis of the bundling member. The risk of the bundling member flipping and deforming is reduced.

[0019] In some embodiments, the first abutment member includes a first body and a first abutment portion. The first body is slidably disposed on the first base along a first direction, and the first body has a second side away from the first base along a third direction. The third direction is parallel to the winding axis of the bundle. Along the third direction, the first abutment portion protrudes from the second side, the first surface and the third surface are disposed on the first abutment portion, and the first abutment portion is used to abut against the end plate of the battery module along the third direction.

[0020] In the above technical solution, the first abutment member includes a first grounding portion protruding from the first body along the third direction, so that the first abutment member abuts against an end plate at one end of the battery module in the first direction along the third direction. The first surface and the third surface are provided on the first abutment portion so that the binding member can be moved from the first surface and the third surface to the outer peripheral surface of the battery module along the third direction.

[0021] In some embodiments, the second abutment mechanism further includes a second base. The second abutment member is slidably disposed on the second base along the first direction. The adjustment mechanism further includes a second adjustment component, the second adjustment component is disposed on the second base, and the second adjustment component is configured to drive the second abutment member to move relative to the second base.

[0022] In the above technical solution, the second abutting member moves along the first direction so that the first abutting member and the second abutting member respectively abut against the inner surfaces of the two ends of the binding member in the first direction. The second adjustment assembly acts on the second abutting member, thereby simplifying the structure of the limiting device and facilitating the design and installation of the limiting device. The second abutting member and the second adjustment assembly are both arranged on the second base, thereby increasing the integration of the second abutting mechanism, thereby facilitating the installation of the second abutting mechanism in the limiting device.

[0023] In a second aspect, an embodiment of the present application provides a strap device including the limiting device provided by any embodiment of the first aspect.

[0024] In the above solution, since the strap device has the limiting device in the embodiment of the first aspect, the strap device also has the beneficial effects in the embodiment of the first aspect.

[0025] In some embodiments, the strapping device further includes a pair of first driving mechanisms and a driving device. The pair of first driving mechanisms are configured to respectively drive a pair of abutting mechanisms to approach or move away from the battery module along a third direction. So that the abutting members of the pair of abutting mechanisms respectively abut against the end plates of the battery module at both ends of the first direction along the third direction. The third direction is perpendicular to the first direction, and the winding axis of the strapping member is parallel to the third direction. The driving device is used to drive the strapping member to move along the third direction so that the strapping member is sleeved outside the battery module.

[0026] In the above scheme, a pair of first driving mechanisms act on a pair of abutting mechanisms respectively, so that the abutting members of the pair of abutting mechanisms abut against the end plates of the battery module at both ends of the first direction respectively along the third direction. The driving device acts on the binding member to make the binding member move along the third direction. The first driving mechanism and the driving device act on the abutting mechanism and the binding member respectively, which can simplify the structure of the strapping device and facilitate the installation and removal of the strapping device.

[0027] In some embodiments, the strap device further comprises a pair of mounting frames, the pair of mounting frames are spaced apart along the first direction. Along the first direction, one of the pair of mounting frames has a fourth side facing the other and a third side facing away from the other. The abutment mechanism is slidably disposed on the third side along the third direction, the first drive mechanism is disposed on the fourth side, and the first drive mechanism is configured to drive the abutment mechanism to move relative to the mounting frame.

[0028] In the above solution, the abutment mechanism and the first driving mechanism located at the same end of the battery module along the first direction are arranged on the same mounting frame, thereby increasing the integration of the strap device and facilitating the installation and removal of the strap device.

[0029] In some embodiments, the first driving mechanism includes a first driving component and a first transmission member, and the first driving component is disposed on the fourth side. The first transmission member is located on one side of the mounting frame in the second direction. The first transmission member has a first end and a second end that are relatively disposed in the first direction, the first end is connected to the first driving component, and the second end is connected to the abutment mechanism. The first direction, the second direction, and the third direction are perpendicular to each other. The first driving component is configured to drive the first transmission member and the abutment mechanism to move along the third direction.

[0030] In the above solution, the first driving component is arranged on the fourth side to fully utilize the space between a pair of mounting members along the first direction, thereby improving the space utilization rate of the belt device.

[0031] In some embodiments, the first transmission member includes a first main body, a first reinforcement portion, and a second reinforcement portion. Along the first direction, an end of the first main body close to the first driving component is the first end, and an end of the first main body close to the abutment mechanism is the second end. The first reinforcement portion is disposed on the first driving portion, and one end of the first reinforcement portion is connected to the first end. One end of the second reinforcement portion is connected to the other end of the first reinforcement portion away from the first main body along the third direction, and the other end of the second reinforcement portion is connected to the second end.

[0032] In the above solution, the first reinforcement part and the second reinforcement part support the first end and the second end of the first body respectively to improve the strength of the first body, thereby reducing the deformation of the first body when the first body drives the abutment mechanism to move along the third direction.

[0033] In some embodiments, the second end is recessed toward the first end to form a first groove. The abutment mechanism further includes a base, the abutment member is slidably disposed on the base along the first direction, and the base has a convex portion inserted into the first groove along the second direction.

[0034] In the above solution, the base is transmission-connected to the first transmission member via the protrusion inserted into the first groove along the second direction, so that when disassembling the first transmission member, only the first end needs to be disassembled, which facilitates disassembly and maintenance of the first transmission member.

[0035] In some embodiments, the strap device further comprises a guide member, which is disposed on the third side and extends along the third direction, and the base is slidably disposed on the guide member, and the guide member is used to guide the base to translate along the third direction.

[0036] In the above solution, the guide member is used to guide the abutment mechanism to translate along the third direction, so as to reduce the risk of the torque between the first driving part and the abutment mechanism causing the base to rotate, thereby causing the abutment member to rotate relative to the binding member.

[0037] In some embodiments, the protrusion has a circular cross-section.

[0038] In the above scheme, the cross-section of the protrusion is circular, so as to facilitate the rotation of the first groove relative to the protrusion, so as to reduce the risk of the abutment member rotating relative to the bundling member due to the inconsistent speed of the first end and the second end moving along the third direction and the torque between the first drive part and the abutment mechanism causing the base to rotate.

[0039] In some embodiments, the driving device includes a second driving component and a third abutment. The third abutment is disposed on the second driving component, and the third abutment is configured to abut against a side of the binding component away from the battery module along a third direction. The second driving component is configured to drive the third abutment to move along the third direction.

[0040] In the above solution, the third abutting member is driven by the second driving component, so that the movement of the third abutting member and the abutting mechanism are relatively independent, thereby simplifying the structure of the belt device and facilitating the disassembly and installation of the belt device.

[0041] In a third aspect, an embodiment of the present application provides a battery production line including the strapping device provided by any embodiment of the second aspect.

[0042] In the above scheme, since the battery production line has the strapping device in the second embodiment, and the strapping device has the limiting device in the first embodiment, the battery production line also has the beneficial effects of the second and first embodiments.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] The term "plurality" used in the present application refers to two or more (including two).

[0074] 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.

[0075] 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.

[0076] The battery mentioned in the embodiments of the present application refers to a single physical module including one or more battery cells to provide higher voltage and capacity.

[0077] In some embodiments, the battery may be a battery module. When there are multiple battery cells, the multiple battery cells are arranged and fixed to form a battery module.

[0078] Commonly used battery modules generally include two end plates, between which multiple battery cells are arranged. The end plate with the output pole of the battery module is also called the output pole end plate, and the end plate without the output pole of the battery module is also called the non-output pole end plate.

[0079] A battery pack may contain multiple battery modules in one row or multiple rows. The arrangement of multiple rows of multiple battery modules may be double rows and multiple columns, multiple rows and double columns, multiple rows and multiple columns, etc. Taking a battery pack containing double rows and multiple columns of battery modules as an example, the first end plate of each column is generally a head output extreme plate, the two adjacent end plates between two rows of battery modules are middle non-output extreme plates, the last end plate of each column is a tail non-output extreme plate, the head output extreme plate and one of the middle non-output extreme plates belong to the first row of battery modules, and one of the middle non-output extreme plates and the tail output extreme plate belong to the second row of battery modules.

[0080] In some embodiments, the battery may be a battery pack, which includes a case and battery cells, wherein the battery cells or battery modules are accommodated in the case.

[0081] In some embodiments, the box body can be used as a part of the chassis structure of the vehicle. For example, part of the box body can become at least a part of the floor of the vehicle, or part of the box body can become at least a part of the cross beam and longitudinal beam of the vehicle.

[0082] In some embodiments, the battery may be an energy storage device, which includes an energy storage container, an energy storage cabinet, and the like.

[0083] At present, from the perspective of market development, batteries have been widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as electric tools, drones, energy storage equipment, etc. With the continuous expansion of battery applications, the market demand is also constantly expanding.

[0084] The development of battery production technology must take into account multiple design factors at the same time, such as energy density, cycle life, discharge capacity, charge and discharge rate and other performance parameters. In addition, battery production efficiency is also one of the key factors to consider.

[0085] Battery cells are usually components of batteries, bundled in groups and placed in a battery box. Bundling pieces are usually used as components for bundling battery cells to improve the reliability of the battery cells in the box and reduce the risk of battery cells shaking in the box, thereby interfering with the battery cells or the box and other components, thereby affecting the reliability of the battery.

[0086] The strapping pieces are usually manufactured in a ring shape, and a plurality of battery cells are bundled into groups using strapping pieces of fixed size. Due to the different batches of incoming materials, the inner circumference of the strapping pieces varies to a certain extent. The distance between the abutments in the existing limiting device cannot be adjusted, so when the inner circumference of the strapping piece is small, it is not easy to put the strapping piece outside the abutment, thereby increasing the loading time and reducing the production efficiency of the battery; when the inner circumference of the strapping piece is large, the abutment does not fit well with the inner surface of the strapping piece, which easily causes the strapping piece to flip and deform when it moves toward the battery module, thereby causing damage to the abutment and the strapping piece, thereby increasing the maintenance time and reducing the production efficiency of the battery.

[0087] Based on the above considerations, in order to make the abutment fit well with the inner surface of different batches of binding pieces, the embodiment of the present application provides a limiting device for limiting the movement of the binding piece, the binding piece is configured as a ring connected end to end, and the limiting device includes a pair of abutment mechanisms and an adjustment mechanism. The abutment mechanism includes an abutment member, and the abutment member of at least one of the pair of abutment mechanisms is configured to be able to move away from and approach the other. The adjustment mechanism is configured to drive the abutment member of at least one of the pair of abutment mechanisms away from the other after the binding piece is sleeved on the outside of the abutment members of the pair of abutment mechanisms, so that the abutment members of the pair of abutment mechanisms respectively abut against the inner surfaces of the two ends of the binding piece in the movement direction of the abutment members. Thus, the movement of the bundle in the direction of movement of the abutment is limited, and the abutment in the pair of abutment mechanisms can play a structural guiding role for the bundle, thereby reducing the risk of the bundle being skewed and damaging the abutment due to the gap between the bundle and the abutment when the bundle moves from the limit device to the battery module along the winding axis of the bundle. This reduces the maintenance time of the limit device, thereby improving the production efficiency of the battery.

[0088] The specific structure of the limiting device 100 is described in detail below with reference to the accompanying drawings.

[0089] The present application embodiment provides a limiting device 100 for limiting the movement of the binding member 500. Figure 1 , Figure 1A schematic diagram of the structure of the limiting device 100 provided in some embodiments of the present application. The binding member 500 is configured as a ring connected end to end, and the limiting device 100 includes a pair of abutment mechanisms 10 and an adjustment mechanism 20. The pair of abutment mechanisms 10 are spaced apart along the first direction X, and the abutment mechanisms 10 include abutment members 11, and the abutment members 11 of at least one of the pair of abutment mechanisms 10 are configured to be able to reciprocate along the first direction X. The adjustment mechanism 20 is configured to drive the abutment members 11 of at least one of the pair of abutment mechanisms 10 to move along the first direction X after the binding member 500 is sleeved on the outside of the abutment members 11 of the pair of abutment mechanisms 10, so that the abutment members 11 of the pair of abutment mechanisms 10 abut against the inner surfaces of the binding member 500 at both ends in the first direction X, respectively.

[0090] The first direction X may be parallel to the length direction of the binding member 500, the second direction Y may be parallel to the width direction of the binding member 500, and the third direction Z may be parallel to the winding axis of the binding member 500. The first direction X, the second direction Y and the third direction Z are perpendicular to each other. It can be understood that Figure 1 In order to facilitate observation of the bundling member 500 , the length of the bundling member 500 in the first direction X is reduced.

[0091] The abutment mechanism 10 is a mechanism in the limiting device 100 for sleeve-mounting the binding member 500 and limiting the binding member 500 from moving in a direction perpendicular to the third direction Z.

[0092] The abutment member 11 is a component in the abutment mechanism 10 for sleeve-mounting the bundling member 500. It can be understood that when the limiting device 100 is used to abut against the battery module (not shown in the figure) along the third direction Z, the abutment member 11 can be a component in the abutment mechanism 10 for imitating the outer peripheral side of the battery module (not shown in the figure) and for abutting against the corresponding position in the battery module (not shown in the figure).

[0093] The abutment member 11 can be made of a material with a certain strength, for example, stainless steel, iron or high-strength plastic, so as to reduce the risk of deformation of the abutment member 11 due to the reaction force of the tying member 500 when the abutment member 11 abuts against the tying member 500 .

[0094] The adjustment mechanism 20 is a mechanism in the limiting device 100 for driving the abutment member 11 of at least one of the pair of abutment mechanisms 10 to move along the first direction X.

[0095] Taking the case where the abutting member 11 of one of the pair of abutting mechanisms 10 can move along the first direction X as an example, before each incoming bundle 500, the movable abutting member 11 is first moved closer to the abutting member 11 of the other abutting mechanism 10 along the first direction X, so that the distance between the abutting members 11 of the pair of abutting mechanisms 10 along the first direction X is reduced, thereby facilitating the insertion of the bundle 500. After the bundle 500 is sleeved outside the pair of abutting mechanisms 10, the movable abutting member 11 is driven by the adjustment mechanism 20 to move away from the abutting member 11 of the other abutting mechanism 10 along the first direction X. In this way, the abutting members 11 of the pair of abutting mechanisms 10 are respectively abutted against the inner surfaces of the two ends of the bundle 500 in the first direction X, thereby adapting to bundles 500 of different incoming batches.

[0096] In the above technical solution, a pair of abutting mechanisms 10 and an adjusting mechanism 20 are provided, and the abutting mechanism 10 includes an abutting member 11. After the bundling member 500 is sleeved outside the abutting member 11 of the pair of abutting mechanisms 10, the adjusting mechanism 20 drives the abutting member 11 of at least one of the pair of abutting mechanisms 10 to move along the first direction X, so that the abutting members 11 of the pair of abutting mechanisms 10 respectively abut against the inner surfaces of the bundling member 500 at both ends in the first direction X. In this way, the abutting member 11 can be adapted to abut against the inner surfaces of the bundling members 500 of different batches. Thus, the movement of the bundle 500 in the direction perpendicular to the third direction Z is restricted, and the abutment member 11 in the pair of abutment mechanisms 10 can play a structural guiding role for the bundle 500, thereby reducing the risk of the bundle 500 being skewed and damaging the abutment member 11 by the bundle 500 due to the gap between the bundle 500 and the abutment member 11 along the first direction X when the bundle 500 moves from the limiting device 100 to the battery module (not shown in the figure). In addition, the maintenance time of the limiting device 100 is reduced, thereby improving the production efficiency of the battery.

[0097] According to some embodiments of this application, please refer to Figure 1 The pair of abutment mechanisms 10 are respectively a first abutment mechanism 10A and a second abutment mechanism 10B. The abutment member 11 of the first abutment mechanism 10A is a first abutment member 11A, and the abutment member 11 of the second abutment mechanism 10B is a second abutment member 11B. The adjustment mechanism 20 includes a first adjustment component 20A, and the first adjustment component 20A is configured to drive the first abutment member 11A to move along the first direction X.

[0098] Exemplarily, the first abutting mechanism 10A and the second abutting mechanism 10B are spaced apart along the first direction X. The first abutting member 11A and the second abutting member 11B are used to abut against inner surfaces of both ends of the binding member 500 in the first direction X, respectively.

[0099] The first adjustment component 20A is a component in the adjustment mechanism 20 for driving the first abutment member 11A to move along the first direction X. Exemplarily, the first adjustment component 20A may be a component that drives the first abutment member 11A to reciprocate along the first direction X, or may be a component that only drives the first abutment member 11A to move away from the second abutment member 11B along the first direction X.

[0100] Optionally, the first adjustment component 20A may be an electrical component such as a linear module, or may be a component that drives the first abutting member 11A to move away from the second abutting member 11B along the first direction X through abutment.

[0101] In the above technical solution, the first abutting member 11A moves along the first direction X so that the first abutting member 11A and the second abutting member 11B respectively abut against the inner surfaces of the two ends of the binding member 500 in the first direction X. The first adjustment component 20A acts on the first abutting member 11A, thereby simplifying the structure of the limiting device 100 and facilitating the design and installation of the limiting device 100.

[0102] According to some embodiments of the present application, referring to Figure 2 and Figure 3 , Figure 2 A schematic structural diagram of a first abutment mechanism 10A and a first adjustment assembly 20A provided in some embodiments of the present application. Figure 3 for Figure 2 The first abutment mechanism 10A further includes a first base 12A. The first abutment member 11A is slidably disposed on the first base 12A along a first direction X. The first adjustment assembly 20A is disposed on the first base 12A, and the first adjustment assembly 20A is configured to drive the first abutment member 11A to move relative to the first base 12A.

[0103] The first base 12A can be used to connect with a frame or a driving component in a strap device (not shown in the figure), and is used to slide the first abutment member 11A and install the first adjustment assembly 20A.

[0104] In some embodiments, reference Figure 3 , the first abutment member 11A and the first base 12A are arranged in sequence along the third direction Z, and the first abutment member 11A has a second side 114A away from the first base 12A along the third direction Z, and a first strip hole 115A penetrating the first abutment member 11A is provided on the second side 114A, and the first strip hole 115A extends along the first direction X. A first mounting hole is provided on a side of the first base 12A facing the first abutment member 11A, and the first mounting hole is connected to the first strip hole 115A. A pin and / or a screw passes through the first strip hole 115A and is connected to the first mounting hole to assemble the first abutment member 11A and the first base 12A, so that the first abutment member 11A can move relative to the first base 12A along the first direction X.

[0105] In an embodiment in which the first abutment member 11A is provided with a first strip hole 115A, the first strip holes 115A may be a plurality of holes arranged at intervals along the second direction Y, and the pins and / or screws may be a plurality corresponding to the first strip holes 115A, thereby limiting the movement of the first abutment member 11A in a direction perpendicular to the third direction Z and at an angle to the first direction X.

[0106] In the embodiment where the first abutment member 11A is connected to the first base 12A by a screw, the first mounting hole is a threaded hole that matches the screw thread, so that the nut end of the screw can press the first abutment member 11A against the first base 12A by rotating the screw, and the screw can also be rotated so that a gap exists between the nut end of the screw and the first abutment member 11A along the third direction Z, so that the first adjustment component 20A drives the first abutment member 11A to move along the first direction X.

[0107] Optionally, the length of the first strip-shaped hole 115A in the first direction X may be 5 mm, 7 mm, 10 mm, etc.

[0108] In the above technical solution, the first abutment member 11A and the first adjustment assembly 20A are both arranged on the first base 12A, thereby increasing the integration of the first abutment mechanism 10A, thereby facilitating the installation of the first abutment mechanism 10A in the limiting device 100 .

[0109] According to some embodiments of the present application, referring to Figure 1 , Figure 2 and Figure 3 , the first adjustment component 20A includes a first adjustment member 21A and a second adjustment member 22A. The first adjustment member 21A is disposed on the first base 12A, and the first adjustment member 21A has a first threaded hole that penetrates the first adjustment member 21A along the first direction X. Along the first direction X, the first abutment member 11A has a first side 113A facing the second abutment member 11B, and the first adjustment member 21A is located between the first side 113A and the second abutment member 11B. The second adjustment member 22A is threadedly matched with the first threaded hole, and one end of the second adjustment member 22A abuts against the first side 113A. The second adjustment member 22A rotates relative to the first threaded hole to adjust the distance between the first abutment member 11A and the second abutment member 11B along the first direction X.

[0110] The first adjusting member 21A is a component in the first adjusting member 21A assembly used to connect with the first base 12A. Exemplarily, the first adjusting member 21A can be detachably connected to the first base 12A by bolts, or the first adjusting member 21A can also be non-detachably connected to the first base 12A by welding or integral molding.

[0111] Optionally, the first adjusting member 21A may be a plate-like structure, one end of which is connected to the surface of the first base 12A facing the first abutting member 11A, and the other end of which extends along the third direction Z.

[0112] The first threaded hole is a threaded hole opened on the first adjusting member 21A, and “penetrating the first adjusting member 21A along the first direction X” means that the axis of the first threaded hole is parallel to the first direction X, and the two ends of the first threaded hole are respectively located on two opposite surfaces of the first adjusting member 21A in the first direction X.

[0113] Optionally, the first threaded hole can also be a threaded hole of a nut. The first adjusting member 21A is provided with a mounting hole that penetrates the first adjusting member 21A along the first direction X. The nut with the first threaded hole is coaxially installed in the above mounting hole to threadably cooperate with the second adjusting member 22A.

[0114] The first side 113A is a side surface of the first abutting member 11A in the first direction X close to the second abutting member 11B.

[0115] “Along the first direction X, the first adjusting member 21A is located between the first side 113A and the second abutment member 11B” may mean that along the first direction X, the first adjusting member 21A is located as a whole between the first abutment member 11A and the second abutment member 11B; or, it may mean that along the first direction X, part of the first adjusting member 21A is located between the first abutment member 11A and the second abutment member 11B.

[0116] It can be understood that in the embodiment where part of the first adjusting member 21A is located between the first abutment 11A and the second abutment 11B along the first direction X, the first threaded hole should be located at the part of the first adjusting member 21A located between the first abutment 11A and the second abutment 11B along the first direction X.

[0117] The second adjusting member 22A is a component in the first adjusting assembly 20A used for abutting against the first side 113A to drive the first adjusting member 21A to move.

[0118] Optionally, the second adjusting member 22A can be a screw, one end of which passes through the first threaded hole and abuts against the first side 113A, and the circumferential side of the screw is threadedly connected to the first threaded hole, so that the second adjusting member 22A can rotate relative to the first threaded hole to drive the first abutting member 11A away from the second abutting member 11B along the first direction X.

[0119] In some embodiments, one end of the second adjusting member 22A can be rotatably connected to the second side 114A, the peripheral side of the second adjusting member 22A has a thread that matches the thread of the first threaded hole, and the other end of the second adjusting member 22A is located on the side of the first adjusting member 21A away from the first abutment member 11A, so that rotating the second adjusting member 22A can drive the first abutment member 11A to reciprocate in the first direction X.

[0120] When the first abutment 11A and the second abutment 11B respectively abut against the inner surfaces of the two ends of the bundling member 500 in the first direction X, taking the first abutment 11A as an example, the bundling member 500 will apply a reaction force to the first abutment 11A pointing to the second abutment 11B along the first direction X. Since one end of the second adjusting member 22A abuts against the first side 113A, the second adjusting member 22A will provide support to the first abutment 11A, thereby limiting the first abutment 11A from approaching the second abutment 11B along the first direction X.

[0121] In the above technical solution, the first adjusting member 21A has a first threaded hole penetrating the first adjusting member 21A along the first direction X, the second adjusting member 22A is threadedly matched with the first threaded hole, and one end of the second adjusting member 22A abuts against the first side 113A of the first abutting member 11A facing the second abutting member 11B along the first direction X, so that the second adjusting member 22A can provide a supporting force to the first abutting member 11A in a direction away from the second abutting member 11B. This limits the movement of the first abutting member 11A relative to the first base 12A toward the second abutting member 11B, thereby reducing the risk of a gap between the first abutting member 11A and the binding member 500 along the first direction X due to the reaction force provided by the binding member 500.

[0122] According to some embodiments of the present application, referring to Figure 1 and Figure 2 The first abutting member 11A has a first surface 116A away from the second abutting member 11B, and the second abutting member 11B has a second surface 116B away from the first abutting member 11A along the first direction X. The first surface 116A and the second surface 116B are configured to abut against part of the inner surface of both ends of the binding member 500 in the first direction X, respectively.

[0123] In some embodiments, the first surface 116A and the second surface 116B may both be planes, and the inner surfaces of the binding member 500 corresponding to the two surfaces are also planes.

[0124] Exemplarily, the first surface 116A and the second surface 116B are both parallel to the third direction Z, so that the binding member 500 can be separated from the abutment member 11 along the third direction Z.

[0125] It can be understood that when the limiting device 100 is used to abut against the battery module (not shown in the figure) along the third direction Z, the first surface 116A and the second surface 116B should be coplanar with the two end surfaces of the battery module (not shown in the figure) in the first direction X, respectively; or, the first surface 116A and the second surface 116B should protrude from the two end surfaces of the battery module (not shown in the figure) in the first direction X, so as to facilitate the movement of the bundling member 500 from the first surface 116A and the second surface 116B to the outer peripheral surface of the battery module (not shown in the figure).

[0126] In the above technical solution, the first surface 116A of the first abutting member 11A and the second surface 116B of the second abutting member 11B abut against the inner surface of the binding member 500, so that the first abutting member 11A and the second abutting member 11B can be in surface contact with the inner surface of the binding member 500 in the process of limiting the movement of the binding member 500 along the first direction X, so that the binding member 500 has a good contact area with the first abutting member 11A and the second abutting member 11B in the process of being limited by the limiting device 100 in the first direction X and in the process of moving along the winding axis of the binding member 500 relative to the limiting device 100. The risk of the binding member 500 turning over and deforming is reduced.

[0127] According to some embodiments of the present application, referring to Figure 1 and Figure 2 The first abutting member 11A and the second abutting member 11B are two each arranged at intervals along the second direction Y. The first direction X, the second direction Y, and the winding axis of the binding member 500 are perpendicular to each other.

[0128] In some embodiments, the first direction X and the second direction Y may both be horizontal directions, and the third direction Z may be a vertical direction. The first direction X may be parallel to the length direction of the binding member 500, the second direction Y may be parallel to the width direction of the binding member 500, and the winding axis of the binding member 500 may be parallel to the third direction Z.

[0129] In the embodiment where the first abutting member 11A has a first surface 116A and the second abutting member 11B has a second surface 116B, the first surfaces 116A of the two first abutting members 11A are coplanar, and the surfaces of the two second abutting members 11B are coplanar.

[0130] In the above technical solution, the first abutment 11A and the second abutment 11B are two pieces spaced apart along the second direction Y, so that after the bundling member 500 is sleeved outside the first abutment 11A and the second abutment 11B, there is a gap between the inner surfaces of the bundling member 500 along the second direction Y to facilitate the insertion of the battery.

[0131] According to some embodiments of the present application, along the second direction Y, the first abutting member 11A has a third surface (not shown in the figure) away from the other first abutting member 11A, and the second abutting member 11B has a fourth surface (not shown in the figure) away from the other second abutting member 11B. The third surfaces (not shown in the figure) of the two first abutting members 11A and the fourth surfaces (not shown in the figure) of the two second abutting members 11B are respectively used to abut against the inner surfaces of the two ends of the bundling member 500 in the second direction Y.

[0132] In some embodiments, the third surface (not shown in the figure) and the fourth surface (not shown in the figure) may both be planes, and the inner surface of the binding member 500 corresponding to the two surfaces is also a plane. The third surface (not shown in the figure) and the fourth surface (not shown in the figure) located on the same side along the second direction Y may be coplanar.

[0133] Exemplarily, the third surface (not shown in the figure) and the fourth surface (not shown in the figure) are both parallel to the third direction Z, so that the binding member 500 can be separated from the abutting member 11 along the third direction Z.

[0134] In the embodiment where the first abutment 11A has both the first surface 116A and the third surface (not shown in the figure), and the second abutment 11B has both the second surface 116B and the fourth surface (not shown in the figure), the first abutment 11A may also have a first arc surface 117A, and the first surface 116A, the first arc surface 117A and the third surface (not shown in the figure) are connected in sequence, and the second abutment 11B may also have a second arc surface 117B, and the second surface 116B, the second arc surface 117B and the fourth surface (not shown in the figure) are connected in sequence. The surface of the binding member 500 corresponding to the first arc surface 117A and the second arc surface 117B is also an arc segment. Exemplarily, the first abutment 11A may be a rectangular parallelepiped structure, and a chamfer is provided at the corner away from the second abutment 11B and away from the other first abutment 11A, that is, the first arc surface 117A. The second abutting member 11B may be a rectangular parallelepiped structure, and a chamfer, i.e., a second arc surface 117B, is provided at a corner away from the first abutting member 11A and the other second abutting member 11B, so as to better abut against the inner surface of the binding member 500, reducing the risk of damaging the arc section at the corner of the binding member 500 during the limiting process.

[0135] In the above technical solution, the third surfaces of the two first abutting members 11A (not shown in the figure) respectively abut against the partial inner surfaces of the two ends of the bundling member 500 in the second direction Y, and the fourth surfaces of the two second abutting members 11B (not shown in the figure) respectively abut against the partial inner surfaces of the two ends of the bundling member 500 in the second direction Y, so that the first abutting members 11A and the second abutting members 11B are in surface contact with the inner surfaces of the two ends of the bundling member 500 in the second direction Y, so that the bundling member 500 has a good contact area with the first abutting members 11A and the second abutting members 11B during the movement in the first direction X and the second direction Y restricted by the limiting device 100 and during the movement along the winding axis of the bundling member 500 relative to the limiting device 100. The risk of the bundling member 500 flipping and deformation is reduced.

[0136] According to some embodiments of the present application, referring to Figure 1 , Figure 2 and Figure 3 The first abutting member 11A includes a first body 111A and a first abutting portion 112A. The first body 111A is slidably disposed on the first base 12A along the first direction X, and the first body 111A has a second side 114A away from the first base 12A along the third direction Z. The third direction Z is parallel to the winding axis of the binding member 500. Along the third direction Z, the first abutting portion 112A protrudes from the second side 114A, the first surface 116A and the third surface are disposed on the first abutting portion 112A, and the first abutting portion 112A is used to abut against an end plate (not shown in the figure) of a battery module (not shown in the figure) along the third direction Z.

[0137] The first body 111A is a portion of the first abutting member 11A used for connecting with the first base 12A.

[0138] In the embodiment where the first abutting member 11A has a second side 114A and the first strip hole 115A is located on the second side 114A, the second side 114A is a side surface of the first body 111A away from the first base 12A along the third direction Z.

[0139] The first abutment portion 112A is a portion of the first abutment member 11A used for sleeve-mounting the bundling member 500. When the first abutment member 11A is used to abut against a battery module (not shown in the figure) along a third direction Z, the first abutment portion 112A is a portion of the first abutment member 11A used to abut against an end plate 610 at one end of the battery module (not shown in the figure) in the first direction X along the third direction Z.

[0140] In the embodiment where the first abutting member 11A has a first surface 116A and a third surface (not shown in the figure), the first surface 116A and the third surface are both located at the first abutting portion 112A.

[0141] It can be understood that the side of the first body 111A away from the second abutment member 11B in the first direction X should be coplanar with the first surface 116A, or the first surface 116A exceeds the side of the first body 111A away from the second abutment member 11B in the first direction X. And the side of the first body 111A away from the other first abutment member 11A in the second direction Y should be coplanar with the third surface, or the third surface exceeds the side of the first body 111A away from the other first abutment member 11A in the second direction Y.

[0142] In the above technical solution, the first abutting member 11A includes a first grounding portion protruding from the first body 111A along the third direction Z, so that the first abutting member 11A abuts against the end plate 610 at one end of the battery module (not shown in the figure) in the first direction X along the third direction Z. The first surface 116A and the third surface are provided on the first abutting portion 112A so that the binding member 500 is moved from the first surface 116A and the third surface to the outer peripheral surface of the battery module (not shown in the figure) along the third direction Z.

[0143] According to some embodiments of the present application, referring to Figure 1 The second abutment mechanism 10B further includes a second base 12. The second abutment member 11B is slidably disposed on the second base 12 along the first direction X. The adjustment mechanism 20 further includes a second adjustment component 20B, which is disposed on the second base 12 and is configured to drive the second abutment member 11B to move relative to the second base 12.

[0144] The second base 12 can be used to connect with a frame or a driving component in a strap device (not shown in the figure), and is used to slide the second abutment member 11B and install the second adjustment assembly 20B.

[0145] The second adjustment component 20B is a component in the adjustment mechanism 20 for driving the second abutment member 11B to move along the first direction X. Exemplarily, the second adjustment component 20B may be a component that drives the second abutment member 11B to reciprocate along the first direction X, or may be a component that only drives the second abutment member 11B along the first direction X away from the first abutment member 11A.

[0146] Optionally, the second adjustment component 20B may be an electrical component such as a linear module, or may be a component that drives the second abutting member 11B to move away from the first abutting member 11A along the first direction X through abutment.

[0147] In the embodiment where the first abutment member 11A has both the first surface 116A and the third surface (not shown in the figure), and the second abutment member 11B has both the second surface 116B and the fourth surface (not shown in the figure), the second abutment member 11B, the second base 12 and the second adjustment assembly 20B are symmetrically arranged with the first abutment member 11A, the first base 12A and the first adjustment assembly 20A, so as to facilitate adjustment so that the first surface 116A and the second surface 116B are respectively coplanar with the two end surfaces of the battery module (not shown in the figure) in the first direction X; or, so that the first surface 116A and the second surface 116B should protrude from the two end surfaces of the battery module (not shown in the figure) in the first direction X, so as to facilitate moving the binding member 500 along the third direction Z from the first surface 116A and the second surface 116B to the outer peripheral side of the battery module (not shown in the figure).

[0148] In the above technical solution, the second abutting member 11B moves along the first direction X so that the first abutting member 11A and the second abutting member 11B respectively abut against the inner surfaces of the two ends of the binding member 500 in the first direction X. The second adjustment assembly 20B acts on the second abutting member 11B, thereby simplifying the structure of the limiting device 100 and facilitating the design and installation of the limiting device 100. The second abutting member 11B and the second adjustment assembly 20B are both arranged on the second base 12, thereby increasing the integration of the second abutting mechanism 10B, thereby facilitating the installation of the second abutting mechanism 10B in the limiting device 100.

[0149] Reference Figure 4 , Figure 4 The structure diagram of a strap device 1000 provided in some embodiments of the present application is shown in FIG. The strap device 1000 provided in an embodiment of the present application includes the limiting device 100 provided in any one of the above embodiments.

[0150] In the above solution, since the strap device 1000 has the limiting device 100 provided by any one of the above embodiments, the strap device 1000 also has the beneficial effects of any one of the above embodiments.

[0151] According to some embodiments of the present application, referring to Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the structure of another strap device 1000 provided in some embodiments of the present application. Figure 6A schematic diagram of the structure of another strapping device 1000 provided for some embodiments of the present application after placing a battery module 600. The strapping device 1000 also includes a pair of first driving mechanisms 200 and a driving device 300. The pair of first driving mechanisms 200 are configured to respectively drive a pair of abutment mechanisms 10 to approach or move away from the battery along a third direction Z. So that the abutment members 11 of the pair of abutment mechanisms 10 respectively abut against the end plates 610 of the battery at both ends of the first direction X along the third direction Z. The third direction Z is perpendicular to the first direction X, and the winding axis of the strapping member 500 is parallel to the third direction Z. The driving device 300 is used to drive the strapping member 500 to move along the third direction Z so that the strapping member 500 is sleeved outside the battery.

[0152] In some embodiments, the first direction X and the second direction Y may both be horizontal directions, and the third direction Z may be a vertical direction. The first direction X may be parallel to the length direction of the binding member 500, and the first direction X may also be parallel to the movement direction of the battery module 600, and the second direction Y may be parallel to the width direction of the binding member 500, and the second direction Y may be a horizontal direction perpendicular to the movement direction of the battery module 600.

[0153] It can be understood that the first driving mechanism 200, the driving device 300 and the limiting device 100 can all be arranged on the frame to form a whole, which is not shown in the above-mentioned frame figure.

[0154] The first driving mechanism 200 is a mechanism in the strap device 1000 for driving the abutment mechanism 10 to move along the third direction Z, so that the abutment members 11 of a pair of abutment mechanisms 10 in the limiting device 100 abut against the end plates 610 at both ends of the battery module 600 in the first direction X along the third direction Z respectively.

[0155] The driving device 300 is used to drive the binding member 500 sleeved outside the abutting members 11 of the pair of abutting mechanisms 10 to approach the battery module 600 along the third direction Z.

[0156] The binding member 500 is sleeved outside the abutting members 11 of the pair of abutting mechanisms 10, and then the battery module 600 moves along the first direction X to be arranged in sequence with the pair of abutting mechanisms 10 along the third direction Z. Then the pair of first driving mechanisms 200 respectively drive the pair of first abutting mechanisms 10A to approach the two ends of the battery module 600 in the first direction X along the third direction Z. So that the abutting members 11 of the pair of abutting mechanisms 10 respectively abut the end plates 610 at the two ends of the battery module 600 in the first direction X along the third direction Z. And the binding member 500 is close to the battery module 600 along the third direction Z. Then the driving device 300 drives the binding member 500 to further approach the battery module 600 along the third direction Z, and finally sleeved outside the peripheral side of the battery module 600. Then the driving device 300 resets along the third direction Z, and the pair of driving mechanisms respectively drive the pair of abutting mechanisms 10 to reset along the third direction Z. Then the battery module 600 moves along the first direction X so as to sleeve the binding member 500 outside the abutting members 11 of the pair of abutting mechanisms 10 to prepare for the next sleeve.

[0157] In the above scheme, a pair of first driving mechanisms 200 act on a pair of abutting mechanisms 10 respectively, so that the abutting members 11 of the pair of abutting mechanisms 10 abut against the end plates 610 at both ends of the battery in the first direction X along the third direction Z. The driving device 300 acts on the binding member 500, so that the binding member 500 moves along the third direction Z. The first driving mechanism 200 and the driving device 300 act on the abutting mechanism 10 and the binding member 500 respectively, which can simplify the structure of the strapping device 1000 and facilitate the installation and removal of the strapping device 1000.

[0158] According to some embodiments of the present application, referring to Figure 5 and Figure 6 , and please refer to Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the structure of the mounting frame 400, the first driving mechanism 200 and the limiting mechanism provided in some embodiments of the present application. Figure 8 A schematic diagram of the structure of the mounting frame 400, the first driving mechanism 200 and the limiting mechanism in another direction provided in some embodiments of the present application. The strap device 1000 also includes a pair of mounting frames 400, and the pair of mounting frames 400 are arranged at intervals along the first direction X. Along the first direction X, one of the pair of mounting frames 400 has a fourth side 410 facing the other and a third side 420 away from the other. The abutment mechanism 10 is slidably arranged on the third side 420 along the third direction Z, the first driving mechanism 200 is arranged on the fourth side 410, and the first driving mechanism 200 is configured to drive the abutment mechanism 10 to move relative to the mounting frame 400.

[0159] The mounting frame 400 is a component in the strapping device 1000 for mounting the first driving mechanism 200 and the abutting mechanism 10. In an embodiment where the strapping device 1000 is applied to a battery production line (not shown in the figure), the mounting frame 400 can be connected to a rack of the battery production line (not shown in the figure).

[0160] The fourth side 410 is a surface where a pair of mounting frames 400 approach each other along the first direction X; the third side 420 is a surface where a pair of mounting frames 400 depart from each other along the first direction X. In some embodiments, the third side 420 and the fourth side 410 are both planes parallel to the third direction Z.

[0161] In the above solution, the abutment mechanism 10 and the first driving mechanism 200 located at the same end of the battery module 600 along the first direction X are arranged on the same mounting frame 400, thereby increasing the integration of the strap device 1000, thereby facilitating the installation and removal of the strap device 1000.

[0162] According to some embodiments of this application, please refer to Figure 7 and Figure 8 The first driving mechanism 200 includes a first driving component 210 and a first transmission member 220, and the first driving component 210 is arranged on the fourth side 410. The first transmission member 220 is located at one side of the mounting frame 400 in the second direction Y. The first transmission member 220 has a first end 221A and a second end 221B that are relatively arranged in the first direction X, the first end 221A is connected to the first driving component 210, and the second end 221B is connected to the abutment mechanism 10. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other. The first driving component 210 is configured to drive the first transmission member 220 and the abutment mechanism 10 to move along the third direction Z.

[0163] The first driving component 210 is a component in the first driving mechanism 200 for driving the first transmission component 220 to move along the third direction Z, so as to drive the abutting component 11 in the abutting mechanism 10 to move along the third direction Z.

[0164] For example, the first driving component 210 may be a hydraulic cylinder, a pneumatic cylinder, a motor, or the like.

[0165] The first transmission member 220 is used to transmit the movement of the first driving member to the components in the abutting mechanism 10 .

[0166] The first end 221A may be detachably connected to the first driving component 210 by bolt connection, or the first end 221A may be non-detachably connected to the first driving component 210 by welding or the like.

[0167] The first transmission member 220 may be made of a rigid material. For example, the first transmission member 220 may be made of stainless steel, iron, or high-strength plastic.

[0168] In the above solution, the first driving component 210 is disposed on the fourth side 410 to fully utilize the space between a pair of mounting components along the first direction X, thereby improving the space utilization of the strap device 1000.

[0169] According to some embodiments of this application, please refer to Figure 7 and Figure 8 The first transmission member 220 includes a first main body 221, a first reinforcement portion 222, and a second reinforcement portion 223. Along the first direction X, one end of the first main body 221 close to the first driving component 210 is the first end 221A, and one end of the first main body 221 close to the abutment mechanism 10 is the second end 221B. The first reinforcement portion 222 is disposed on the first driving portion, and one end of the first reinforcement portion 222 is connected to the first end 221A. One end of the second reinforcement portion 223 is connected to the other end of the first reinforcement portion 222 away from the first main body 221 along the third direction Z, and the other end of the second reinforcement portion 223 is connected to the second end 221B.

[0170] The first main body 221 is the portion of the first transmission member 220 that connects the abutment mechanism 10 and the first driving member 210, the first reinforcement portion 222 is the portion of the first transmission member 220 that is connected to the first driving member 210, and the second reinforcement portion 223 is the portion of the first transmission member 220 that provides support force to the second end 221B.

[0171] It can be understood that the first driving component 210 can drive the first body 221 , the first reinforcement part 222 and the second reinforcement part 223 to move along the third direction Z.

[0172] Optionally, the first body 221 , the first reinforcement portion 222 and the second reinforcement portion 223 may be connected by welding, or may be connected to each other by integral molding.

[0173] In some embodiments, the first body 221 may be in the shape of an elongated strip, the first body 221 extends along the first direction X, the end of the first body 221 close to the first driving component 210 is the first end 221A, the end of the first body 221 close to the abutting mechanism 10 is the second end 221B, the first reinforcing portion 222 is in the shape of an elongated strip, one end of the first reinforcing portion 222 is connected to one side of the first end 221A in the third direction Z, and the other end of the first reinforcing portion 222 extends along the third direction Z. The second reinforcing portion 223 is in the shape of an elongated strip, one end of the second reinforcing portion 223 is connected to the other end of the first reinforcing portion 222, and the other end of the second reinforcing portion 223 is connected to one side of the second end 221B close to the first reinforcing portion 222 in the third direction Z. Thus, the first body 221, the first reinforcing portion 222 and the second reinforcing portion 223 enclose and form a hollow triangle, thereby reducing the weight of the first transmission member 220.

[0174] In the above solution, the second reinforcing portion 223 increases the connection area between the first transmission member 220 and the first driving member 210, thereby increasing the connection strength. At the same time, the first reinforcing portion 222 and the second reinforcing portion 223 respectively support the first end 221A and the second end 221B of the first body 221 to increase the strength of the first body 221, thereby reducing the risk of deformation of the first body 221 when the first body 221 drives the abutting mechanism 10 to move along the third direction Z.

[0175] According to some embodiments of the present application, referring to Figure 8 and 9 , Fig. 9 for Figure 8 The second end 221B is recessed toward the first end 221A to form a first groove 221C. The abutment mechanism 10 further includes a base 12, the abutment member 11 is slidably disposed on the base 12 along the first direction X, and the base 12 has a convex portion 121 inserted into the first groove 221C along the second direction Y.

[0176] The first groove 221C is a groove formed by the second end 221B being recessed along the first direction X toward the first end 221A.

[0177] The base 12 is a component of the abutment mechanism 10 for mounting the abutment member 11 .

[0178] In an embodiment where the pair of abutting mechanisms 10 are respectively a first abutting mechanism 10A and a second abutting mechanism 10B, the base 12 in the first abutting mechanism 10A is a first base 12A, and the base 12 in the second abutting mechanism 10B is a second base 12 .

[0179] In the embodiment in which the first end 221A is detachably connected to the first driving component 210 by bolts, when the first transmission component 220 needs to be repaired, it is only necessary to remove the first end 221A from the first driving component 210 and then move the first transmission component 220 away from the mounting frame 400 along the second direction Y so that the protrusion 121 slides out of the first groove 221C, and then the first transmission component 220 can be removed.

[0180] In the above solution, the base 12 is connected to the first transmission member 220 by the protrusion 121 inserted into the first groove 221C along the second direction Y. Therefore, when disassembling the first transmission member 220, only the first end 221A needs to be disassembled, which facilitates the disassembly and maintenance of the first transmission member 220.

[0181] According to some embodiments of the present application, referring to Figure 8 and 9The strap device 1000 further includes a guide member 430, which is disposed on the third side 420 and extends along the third direction Z. The base 12 is slidably disposed on the guide member 430, and the guide member 430 is used to guide the base 12 to translate along the third direction Z.

[0182] The guide member 430 is a component in the strap device 1000 for guiding the base 12 to translate along the third direction Z.

[0183] In some embodiments, the guide member 430 is a guide rod, which is disposed on the third side 420 and extends along the third direction Z. A through hole is provided on the base 12 and penetrates the base 12 along the third direction Z. The through hole is adapted to the guide member 430, and the cross section of the guide member 430 may be square. The through hole is sleeved outside the guide member 430 and can slide along the third direction Z relative to the guide member 430.

[0184] In some embodiments, the guide member 430 is a guide rail, which is disposed on the third side 420 and extends along the third direction Z. A second groove is provided on the base 12 and penetrates the base 12 along the third direction Z. The second groove is a dovetail groove adapted to the guide member 430. The dovetail groove is sleeved outside the guide member 430 and can slide along the third direction Z relative to the guide member 430.

[0185] Since the first driving component 210 and the base 12 are located at the fourth side 410 and the third side 420 respectively, that is, along the first direction X, there is a certain distance between the first driving component 210 and the base 12, and the first driving component 210 provides a driving force along the third direction Z to the base 12 through the first transmission member 220. For example, the first driving component provides a driving force to the base 12 close to the battery module (not shown in the figure) along the third direction Z through the first transmission member 220. The driving force causes the first driving component 210 to generate a torque on the base 12, thereby causing the base 12 to have a tendency to rotate. The guide member 430 is used to provide a supporting force opposite to the first direction X to the base 12, so as to offset the torque generated by the first driving component 210 on the base 12, thereby causing the base 12 to translate along the third direction Z.

[0186] In the above solution, the guide member 430 is used to guide the abutment mechanism 10 to translate along the third direction Z, so as to reduce the risk that the torque between the first driving part and the abutment mechanism 10 causes the base 12 to rotate, thereby causing the abutment member 11 to rotate relative to the binding member 500.

[0187] According to some embodiments of the present application, the cross section of the protrusion 121 is circular.

[0188] The “cross section of the convex portion 121 ” refers to a cross section obtained by cutting the convex portion 121 in a plane perpendicular to the second direction Y.

[0189] In the above scheme, the cross-section of the protrusion 121 is circular, so as to facilitate the rotation of the first groove 221C relative to the protrusion 121, so as to reduce the risk of the abutment 11 rotating relative to the strapping member 500 due to the inconsistent speed of the first end 221A and the second end 221B moving along the third direction Z and the torque between the first drive part and the abutment mechanism 10 causing the base 12 to rotate.

[0190] According to some embodiments of the present application, referring to Figure 5 The driving device 300 includes a second driving component 310 and a third abutting member 320. The third abutting member 320 is disposed on the second driving component 310, and the third abutting member 320 is configured to abut against the side of the binding member 500 away from the battery along the third direction Z. The second driving component 310 is configured to drive the third abutting member 320 to move along the third direction Z.

[0191] The second driving component 310 is a component in the driving device 300 for driving the third abutting member 320 to move along the third direction Z.

[0192] Exemplarily, the second driving component 310 may be a hydraulic cylinder, a pneumatic cylinder, a motor, or the like.

[0193] The third abutting member 320 is a member used to abut against the binding member 500 to drive the binding member 500 to move along the third direction Z. The third abutting member 320 may be made of polyoxymethylene.

[0194] In some embodiments, the side surface of the third abutting member 320 facing the abutting member 11 abuts against the side surface of the abutting member 11 used for abutting against the binding member 500 .

[0195] In the above solution, the third abutment member 320 is driven by the second driving member 310, so that the movement of the third abutment member 320 and the abutment mechanism 10 are relatively independent, thereby simplifying the structure of the strap device 1000 and facilitating the disassembly and installation of the strap device 1000.

[0196] An embodiment of the present application provides a battery production line including the strapping device 1000 provided in any one of the above embodiments.

[0197] In the above solution, since the battery production line has the strapping device 1000 provided by any one of the above embodiments, and the strapping device 1000 has the limiting device 100 provided by any one of the above embodiments, the battery production line also has the beneficial effects of any one of the above embodiments.

[0198] According to some embodiments of the present application, referring to Figure 1 - Figure 3 , a limiting device 100 is provided.

[0199] The limiting device 100 includes a pair of abutting mechanisms 10 and an adjusting mechanism 20 . The pair of abutting mechanisms 10 are distributed along the first direction X at intervals.

[0200] The pair of abutting mechanisms 10 are respectively a first abutting mechanism 10A and a second abutting mechanism 10B. The adjusting mechanism 20 includes a first adjusting component 20A and a second adjusting component 20B. The first abutting mechanism 10A and the first adjusting component 20A are symmetrically arranged with the second abutting mechanism 10B and the second adjusting component 20B.

[0201] The abutment mechanism 10 includes a base 12 and an abutment member 11 .

[0202] Taking the first abutment mechanism 10A and the first adjustment assembly 20A as an example, the first abutment mechanism 10A includes a first base 12A and a first abutment member 11A.

[0203] The first abutment member 11A and the first base 12A are arranged in sequence along the third direction Z. The first abutment member 11A has a second side 114A facing away from the first base 12A along the third direction Z. A first strip hole 115A penetrating the first abutment member 11A is provided on the second side 114A. The first strip hole 115A extends along the first direction X. A first mounting hole is provided on a side of the first base 12A facing the first abutment member 11A. The first mounting hole is connected to the first strip hole 115A. A pin and / or a screw passes through the strip hole and is connected to the first mounting hole to assemble the first abutment member 11A and the first base 12A, so that the first abutment member 11A can move along the first direction X relative to the first base 12A.

[0204] The first strip holes 115A are arranged in a plurality along the second direction Y at intervals, and the pins and / or screws can be a plurality corresponding to the first strip holes 115A, thereby limiting the first abutment member 11A from moving in a direction perpendicular to the third direction Z and forming an angle with the first direction X.

[0205] The first adjustment component 20A includes a first adjustment member 21A and a second adjustment member 22A. The first adjustment member 21A is disposed on the first base 12A, and the first adjustment member 21A has a first threaded hole that penetrates the first adjustment member 21A along the first direction X. Along the first direction X, the first abutment member 11A has a first side 113A facing the second abutment member 11B, and the first adjustment member 21A is located between the first side 113A and the second abutment member 11B. The second adjustment member 22A is threadedly matched with the first threaded hole, and one end of the second adjustment member 22A abuts against the first side 113A. The second adjustment member 22A rotates relative to the first threaded hole to adjust the distance between the first abutment member 11A and the second abutment member 11B along the first direction X.

[0206] In the above technical solution, after the binding member 500 is sleeved on the outside of the abutting members 11 of the pair of abutting mechanisms 10, the adjusting mechanism 20 drives the abutting member 11 of at least one of the pair of abutting mechanisms 10 to move along the first direction X, so that the abutting members 11 of the pair of abutting mechanisms 10 respectively abut against the inner surfaces of the binding member 500 at both ends in the first direction X. In this way, the abutting members 11 can be adapted to abut against the inner surfaces of the binding members 500 of different batches. Thus, the movement of the bundle 500 in the direction perpendicular to the third direction Z is restricted, and the abutment member 11 in the pair of abutment mechanisms 10 can play a structural guiding role for the bundle 500, thereby reducing the risk of the bundle 500 being skewed and damaging the abutment member 11 by the bundle 500 due to the gap between the bundle 500 and the abutment member 11 along the first direction X when the bundle 500 moves from the limiting device 100 to the battery module (not shown in the figure). In addition, the maintenance time of the limiting device 100 is reduced, thereby improving the production efficiency of the battery.

[0207] According to some embodiments of the present application, referring to Figure 4 - Fig. 9 , a strap device 1000 is provided.

[0208] The strapping device 1000 includes the above-mentioned limiting device 100 , a pair of first driving mechanisms 200 , a driving device 300 and a pair of mounting frames 400 .

[0209] The pair of mounting frames 400 are spaced apart along the first direction X. Along the first direction X, one of the pair of mounting frames 400 has a fourth side 410 facing the other and a third side 420 facing away from the other.

[0210] The strapping device 1000 further includes a guide member 430, which is a guide rail, and is disposed on the third side 420 and extends along the third direction Z. A second groove is provided on the base 12 and penetrates the base 12 along the third direction Z. The second groove is a dovetail groove adapted to the guide member 430. The dovetail groove is sleeved outside the guide member 430 and can slide along the third direction Z relative to the guide member 430.

[0211] The first driving mechanism 200 includes a first driving component 210 and a first transmission member 220, and the first driving component 210 is disposed on the fourth side 410. The first transmission member 220 is located at one side of the mounting frame 400 in the second direction Y. The first transmission member 220 has a first end 221A and a second end 221B that are oppositely disposed in the first direction X, and the first end 221A is connected to the first driving component 210.

[0212] The second end 221B is recessed toward the first end 221A to form a first groove 221C. The base 12 has a convex portion 121 inserted into the first groove 221C along the second direction Y. The cross section of the convex portion 121 is circular.

[0213] The driving device 300 includes a second driving component 310 and a third abutting member 320. The third abutting member 320 is disposed on the second driving component 310, and the third abutting member 320 is configured to abut against the side of the binding member 500 away from the battery along the third direction Z. The second driving component 310 is configured to drive the third abutting member 320 to move along the third direction Z.

[0214] In the above scheme, the guide member 430 is used to guide the abutment mechanism 10 to translate along the third direction Z, so as to reduce the risk that the base 12 rotates due to the torque between the first driving part and the abutment mechanism 10, thereby causing the abutment member 11 to rotate relative to the binding member 500. At the same time, since the cross section of the convex portion 121 is circular, it is convenient for the first groove 221C to rotate relative to the convex portion 121, so as to reduce the risk that the abutment member 11 rotates relative to the binding member 500 due to the inconsistent speed of the first end 221A and the second end 221B moving along the third direction Z and the torque between the first driving part and the abutment mechanism 10 causing the base 12 to rotate. Furthermore, the base 12 is connected to the first transmission member 220 through the convex portion 121 inserted in the first groove 221C along the second direction Y. Therefore, when disassembling the first transmission member 220, only the first end 221A needs to be disassembled, which facilitates the disassembly and maintenance of the first transmission member 220. In this way, the maintenance time of the strap device 1000 is reduced, thereby improving the production efficiency of the battery.

[0215] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0216] The above embodiments are only used to illustrate the technical solution of the present application and are not used to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
