Description

Technical Field

[0001] The present application relates to the technical field of loading structures, and in particular provides a grasping device and a battery production line. Background Art

[0002] Lithium batteries have become one of the remarkable power sources due to their advantages such as high energy density, long cycle life, and green pollution-free.

[0003] During the production process of batteries, it is necessary to grasp and load materials such as connecting tabs to achieve automated production. However, since materials such as connecting tabs are generally stacked in a crosswise and misaligned manner, when grasping the materials, the problem of overlapping of the stacked materials is likely to occur, resulting in misgrasping of multiple materials, which in turn affects subsequent production. Summary of the Utility Model

[0004] The purpose of the embodiments of the present application is to provide a grasping device and a battery production line, aiming to solve the problem that in the related art, when grasping materials stacked in a crosswise and misaligned manner, it is easy to misgrasp multiple materials, which affects subsequent production.

[0005] To achieve the above purpose, the technical solution adopted in the embodiments of the present application is as follows:

[0006] In a first aspect, the embodiments of the present application provide a grasping device, including a main body structure, a grasping structure, and a supporting structure; the grasping structure is arranged on the main body structure, and the grasping structure has a grasping end facing a first direction; the supporting structure is movably arranged on the main body structure along the first direction, and the supporting structure has an abutting end facing the first direction; in the initial state, in the first direction, the distance from the abutting end to the main body structure is greater than the distance from the grasping end to the main body structure.

[0007] The beneficial effect of the embodiments of the present application: For the grasping device provided by the embodiments of the present application, when the grasping end of the grasping structure grasps the material below the first direction, in the initial state, the distance from the abutting end of the supporting structure to the main body structure is greater. Thus, the abutting end can abut against the material stacked crosswise below the material grasped by the grasping end, and the supporting structure moves in a direction opposite to the first direction due to the formation of the abutment at the abutting end; during the process of the main body structure driving the grasping structure to move in a direction opposite to the first direction to grasp the material, the supporting structure can move relative to the main body structure in the first direction according to its own gravity and continuously form an abutment against the material stacked crosswise below the material to be grasped, so that the stacked materials can be separated, and thus the situation of the grasping device misgrasping multiple materials can be effectively reduced to ensure the subsequent production process.

[0008] In some embodiments, the grasping device further includes a connecting structure, and the connecting structure is connected to the main body structure; the supporting structure is slidably connected to the connecting structure along the first direction.

[0009] By adopting the above technical solution, the supporting structure can slide on the connecting structure, so that the supporting structure abuts against the materials stacked below the grabbed material, thereby achieving the purpose of separating the stacked materials and reducing the probability of the stacked materials being mis-grabbed due to the coincidence of the laminated sheets.

[0010] In some embodiments, the connecting structure is provided with a connecting hole along the first direction, the supporting structure is inserted into the connecting hole, and the supporting structure is in sliding fit with the connecting hole.

[0011] By adopting the above technical solution, the supporting structure can slide in the connecting hole, so that the supporting structure abuts against the materials stacked below the grabbed material, thereby achieving the purpose of separating the stacked materials and reducing the probability of the stacked materials being mis-grabbed due to the coincidence of the laminated sheets.

[0012] In some embodiments, a first elastic member is disposed in the connecting hole, and in the first direction, the opposite ends of the first elastic member respectively abut against the supporting structure and the inner wall of the hole of the connecting hole.

[0013] By adopting the above technical solution, during the process that the grabbing end of the grabbing structure grabs the material and moves away from the first direction, the first elastic member can act on the supporting structure, so that the supporting structure can keep abutting against the materials stacked below the grabbed material, so as to further reduce the probability of the stacked materials being mis-grabbed due to the coincidence of the laminated sheets.

[0014] In some embodiments, the connecting structure is detachably connected to the main body structure.

[0015] By adopting the above technical solution, the connecting structure can be disassembled and assembled, so that the supporting structure in sliding fit with the connecting hole can also be disassembled and assembled. Therefore, it is convenient to maintain, replace and adjust the supporting structure.

[0016] In some embodiments, a threaded connection section is formed on the outer peripheral wall of the connecting structure, a threaded hole is provided on the main body structure, and the threaded connection section is screwed into the threaded hole.

[0017] By adopting the above technical solution, the connecting structure can be screwed into the threaded hole of the main body structure through the threaded connection section, so that the connecting structure can adjust its position in the first direction according to the threaded connection section, and further can adjust the position of the supporting structure in the first direction to improve its scope of application.

[0018] In some embodiments, a fastening nut is screwed on the part of the threaded connection section extending out of the threaded hole, and the fastening nut abuts against the main body structure.

[0019] By adopting the above technical solution, the fastening nut can be screwed onto the threaded connection section and abutted against the main structure, so as to lock the connection structure to the main structure.

[0020] In some embodiments, a buffer structure is provided on the abutting end.

[0021] By adopting the above technical solution, by providing a buffer structure on the abutting end, the buffer structure can contact the material instead of the abutting end, so as to reduce the damage caused to the material.

[0022] In some embodiments, an assembly hole is formed in the main structure, the support structure is inserted into the assembly hole, and the support structure is in sliding fit with the assembly hole.

[0023] By adopting the above technical solution, the support structure can slide in the assembly hole, so that the support structure abuts against the materials stacked below the grabbed material, thereby separating the stacked materials and reducing the probability of mis-grabbing the stacked materials due to overlapping of the laminations.

[0024] In some embodiments, a second elastic member is provided in the assembly hole. In the first direction, the opposite ends of the second elastic member respectively abut against the support structure and the inner wall of the hole of the assembly hole.

[0025] By adopting the above technical solution, during the process of the grabbing end of the grabbing structure grabbing the material and moving away from the first direction, the second elastic member can act on the support structure, so that the support structure can keep abutting against the materials stacked below the grabbed material, further reducing the probability of mis-grabbing the stacked materials due to overlapping of the laminations.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0046] In this application, unless otherwise clearly specified and defined, terms such as "installed", "connected", "linked", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] Currently, from the perspective of the development of the market situation, the application of power batteries is becoming more and more extensive. Power batteries are not only applied to energy storage power systems such as hydroelectric, thermal, wind, and solar power stations, but also widely used in electric transportation such as electric bicycles, electric motorcycles, and electric vehicles, as well as in multiple fields such as military equipment and aerospace. With the continuous expansion of the application fields of power batteries, the market demand is also constantly increasing.

[0048] During the production process of the battery, it is necessary to grasp and feed materials such as connecting pieces to achieve automated production. Before feeding, since the materials are stacked in a crosswise and misaligned manner, it is very easy for the materials adjacent up and down to have the problem of overlapping laminations. Taking the connecting piece as an example of the material, the connecting piece is designed with a convex cap structure. Thus, the connecting pieces stacked up and down are prone to lamination overlap due to the nesting of the convex cap structures, resulting in adhesion between the adjacent connecting pieces up and down. Therefore, during the feeding process, the materials adjacent up and down are easily mis-grasped due to the overlap, which further leads to the problem of product scrapping due to multiple pieces of materials during the subsequent production process.

[0049] Based on the above considerations, in order to solve the problem that related technologies are prone to mis-grasping multiple materials when grasping materials stacked in a crosswise and misaligned manner, which affects the subsequent production, a grasping device is designed. When the grasping end of the grasping structure grasps the material in the first direction, the abutting end of the supporting structure can abut against the material below the material to be grasped. Thus, when the grasping end grasps the material and moves in the direction opposite to the first direction, the abutting end can abut against the material below to separate it from the grasped material, thereby effectively reducing the situation of the grasping device mis-grasping multiple materials and ensuring the subsequent production process.

[0050] The gripping device disclosed in the embodiments of the present application can be used in the feeding process of battery production. The gripping device can be used to perform gripping and feeding operations on materials such as adapter plates and other sheet-like structures.

[0051] For the convenience of description in the following embodiments, a gripping device in an embodiment of the present application for gripping an adapter plate is taken as an example for illustration.

[0052] Please refer to Figure 1 and Figure 2 As shown in FIGS. and, an embodiment of the present application provides a gripping device 100, including a main body structure 10, a gripping structure 20, and a support structure 30; the gripping structure 20 is disposed on the main body structure 10, and the gripping structure 20 has a gripping end 21 facing a first direction G; the support structure 30 is movably disposed on the main body structure 10 along the first direction G, and the support structure 30 has an abutting end 31 facing the first direction G; in the initial state, in the first direction G, the distance d from the abutting end 31 to the main body structure 10 is greater than the distance f from the gripping end 21 to the main body structure 10.

[0053] The main body structure 10 is used for the assembly and connection of the gripping structure 20 and the support structure 30. The main body structure 10 can be, but is not limited to, structures such as mounting plates, mounting blocks, mounting brackets, etc. The main body structure 10 can be connected to an external driving device (such as a cylinder, a hydraulic cylinder, etc.), and the driving device is used to drive the main body structure 10 to move, so that the main body structure 10 can drive the gripping structure 20 to move and grip materials such as adapter plates.

[0054] The gripping structure 20 is used to grip materials such as adapter plates; the gripping structure 20 can be fixedly connected to the main body structure 10 by means of welding, fastener connection, etc.

[0055] Wherein, the first direction G can be any direction. According to the way of gripping the stacked adapter plates, the first direction G is generally the direction of gravity, or any direction forming an acute angle with the direction of gravity, etc. For the convenience of description below, the first direction G is taken as an example parallel to the direction of gravity for specific illustration.

[0056] The gripping structure 20 has a gripping end 21, and the gripping end 21 is used to perform a gripping action. The gripping end 21 is set to face the first direction G. Thus, the gripping end 21 can perform a gripping operation on the stacked adapter plates from top to bottom in the first direction G. Optionally, the gripping end 21 can be, but is not limited to, structures such as suction cups, clamping jaws, etc. Exemplarily, taking a suction cup as an example, the gripping structure 20 moves until the gripping end 21 abuts against the adapter plate, so that the suction cup's gripping end 21 can evacuate and adsorb the adapter plate to achieve gripping the material and performing a feeding operation.

[0057] The support structure 30 is movably arranged on the main body structure 10 along the first direction G; optionally, the support structure 30 can be slidably connected to the main body structure 10. For example, a slot structure can be formed on the main body structure 10 so that the support structure 30 is slidably fitted to the slot structure to achieve free movement in the first direction G; alternatively, other structures can be connected to the main body structure 10, and the support structure 30 is slidably connected to the other structures; or, a driving structure can be arranged on the main body structure 10 to drive the support structure 30 to reciprocate along the first direction G.

[0058] The support structure 30 includes, but is not limited to, structures such as support columns, support rods, and support frames.

[0059] The abutting end 31 is one end of the support structure 30 facing the first direction G, and the abutting end 31 is used to abut against materials such as adapter plates.

[0060] The initial state refers to the state when the grasping device 100 has not started the grasping operation. At this time, the support structure 30 slides down to the limit position in the first direction G under its own gravity, that is, the distance from the abutting end 31 to the main body structure 10 is the largest in the initial state.

[0061] Wherein, the distance d from the above-mentioned abutting end 31 to the main body structure 10 refers to the distance formed between the end face of the abutting end 31 facing the first direction G and the end face of the main body structure 10 facing the first direction G; it should be understood that when other structures for assisting in abutting against materials are arranged on the abutting end 31, the distance d from the abutting end 31 to the main body structure 10 should be considered as the distance formed between the end face of the structure arranged on the abutting end 31 for assisting in abutting against materials facing the first direction G and the end face of the main body structure 10 facing the first direction G.

[0062] Similarly, the distance f from the grasping end 21 to the main body structure 10 refers to the distance formed between the end face of the grasping end 21 facing the first direction G and the end face of the main body structure 10 facing the first direction G.

[0063] By setting the distance d from the abutting end 31 to the main body structure 10 in the initial state to be greater than the distance f from the grasping end 21 to the main body structure 10, when the grasping end 21 grasps the adapter plate, the abutting end 31 can abut against the adapter plate below the grasped adapter plate; and the support structure 30 is movably arranged on the main body structure 10, and the support structure 30 can adaptively adjust the position where the abutting end 31 abuts against the adapter plate by moving relative to the main body structure 10 and away from the first direction G, so as to improve the applicable range of the grasping device 100.

[0064] After the grasping end 21 of the grasping structure 20 grasps the transfer sheet, the main body structure 10 can drive the grasping end 21 to move the grasped transfer sheet in a direction away from the first direction G to complete the grasping; at this time, the supporting structure 30 can move relative to the main body structure 10 in the first direction G according to its own gravity, so that the abutting end 31 can continue to abut against the transfer sheet below for a period of time. Thus, the grasped transfer sheet and the adjacent stacked transfer sheets can be separated.

[0065] For the grasping device 100 provided by the embodiment of the present application, when the grasping end 21 of the grasping structure 20 grasps the material below the first direction G, in the initial state, the distance d from the abutting end 31 of the supporting structure 30 to the main body structure 10 is larger. Thus, the abutting end 31 can abut against the material stacked crosswise below the material grasped by the grasped end 21, and the supporting structure 30 moves in a direction away from the first direction G due to the abutment formed by the abutting end 31; during the process that the main body structure 10 drives the grasping structure 20 to move in a direction away from the first direction G to grasp the material, the supporting structure 30 can move relative to the main body structure 10 in the first direction G according to its own gravity and continuously abut against the material stacked crosswise below the grasped material, so that the stacked materials can be separated, and further, the situation that the grasping device 100 misgrasps multiple materials can be effectively reduced to ensure the subsequent production process.

[0066] Please refer to Figure 1 and Figure 2 , in some embodiments, the grasping device 100 further includes a connecting structure 40, and the connecting structure 40 is connected to the main body structure 10; the supporting structure 30 is slidably connected to the connecting structure 40 along the first direction G.

[0067] Wherein, the connecting structure 40 can be but is not limited to structures such as connecting columns, connecting rods, connecting blocks, connecting plates, connecting brackets, etc.; the connecting structure 40 can be connected to the main body structure 10 by means of fastener connection, screw connection, snap connection, welding, etc.

[0068] The supporting structure 30 is slidably connected to the connecting structure 40 along the first direction G. Optionally, a sliding groove can be formed in the connecting structure 40 along the first direction G, and the supporting structure 30 is slidably arranged in the sliding groove to achieve the sliding connection; or, a jack can be formed in the connecting structure 40 along the first direction G, and one end of the supporting structure 30 away from the abutting end 31 is inserted into the jack, and the supporting structure 30 is arranged to be slidably matched with the jack, so as to realize the movement of the supporting structure 30 in the first direction G.

[0069] With such a setting, the supporting structure 30 can slide on the connecting structure 40, so that the supporting structure 30 abuts against the materials stacked below the grasped material, thereby achieving the purpose of separating the stacked materials and reducing the probability that the stacked materials are adhered and misgrasped due to the coincidence of the stacked sheets.

[0070] Please refer to Figures 1 to 3 , in some embodiments, the connecting structure 40 is provided with a connecting hole 41 along the first direction G, and the supporting structure 30 is inserted into the connecting hole 41, and the supporting structure 30 is slidably engaged with the connecting hole 41.

[0071] Among them, the connecting hole 41 can be but is not limited to a circular hole, a rectangular hole or other polygonal holes; thus, the connecting structure 40 can be but is not limited to a cylindrical top post, a prismatic top post, etc.

[0072] Exemplarily, in some embodiments, one end of the connecting structure 40 facing the first direction G is provided with a socket having a circular cross-section inwardly, and the cross-section of the supporting structure 30 corresponds to a circular shape; the supporting structure 30 is slidably engaged with the connecting hole 41, and thus, the supporting structure 30 can reciprocally move in the first direction G.

[0073] With such a setting, the supporting structure 30 can slide within the connecting hole 41, so that the supporting structure 30 can abut against the materials stacked below the material to be grabbed, thereby achieving the purpose of separating the stacked materials and reducing the probability of the stacked materials being mis-grabbed due to the coincidence of the stacked sheets.

[0074] Please refer to Figures 1 to 3 , in some embodiments, a first elastic member 50 is disposed in the connecting hole 41. In the first direction G, opposite ends of the first elastic member 50 respectively abut against the supporting structure 30 and the inner wall of the hole of the connecting hole 41.

[0075] Among them, the first elastic member 50 is an elastic structural member; the first elastic member 50 includes but is not limited to a spring, an elastic gasket, etc. One end of the first elastic member 50 abuts against the supporting structure 30, and the opposite end of the first elastic member 50 abuts against the inner wall of the hole of the connecting hole 41 (for example, the inner bottom wall of the hole opposite to the hole end); thus, the first elastic member 50 can act on the supporting structure 30 and keep the supporting structure 30 in a state of being abutted, that is, when the supporting structure 30 is not subjected to other external forces, it can maintain the initial state of extending out of the connecting hole 41 to the limit state.

[0076] During the process of grabbing the material, the abutting end 31 of the supporting structure 30 can abut against the lower transfer sheet, so that the supporting structure 30 can be inserted into the connecting hole 41 and compress the first elastic member 50. During the process of moving away from the first direction G after completing the grabbing action, the first elastic member 50 will continuously act on the supporting structure 30 according to its own elastic restoring force, so that the abutting end 31 of the supporting structure 30 can continuously abut against the lower transfer sheet; until the supporting structure 30 extends out of the connecting hole 41 to the limit state, at this time the abutting end 31 faces away from the first direction G and leaves the lower transfer sheet.

[0077] With such a setting, during the process that the grasping end 21 of the grasping structure 20 grasps the material and moves away from the first direction G, the first elastic member 50 can act on the supporting structure 30, so that the supporting structure 30 can keep abutting against the material stacked below the grasped material, thereby further reducing the probability that the stacked materials are mis-grasped due to the coincidence of the laminations.

[0078] Please refer to Figures 1 to 3 , in some embodiments, the connecting structure 40 is detachably connected to the main body structure 10.

[0079] Optionally, the connecting structure 40 can be connected to the main body structure 10 by means of fasteners (bolts, screws, etc.); thus, the connecting structure 40 can be disassembled by removing the fasteners.

[0080] Or, the connecting structure 40 can be connected to the main body structure 10 by screwing; for example, a threaded hole is formed in the main body structure 10, and a threaded structure is provided on the connecting structure 40, and the connecting structure 40 is screwed into the threaded hole to achieve the detachable connection of the connecting structure 40; or, a threaded structure can be provided on the main body structure 10, and a threaded hole is formed in the connecting structure 40, and the detachable connection of the connecting structure 40 can also be achieved.

[0081] Or, the connecting structure 40 can also be detachably connected by means of snap connection or the like.

[0082] With such a setting, the connecting structure 40 can be disassembled and assembled, so that the supporting structure 30 that is slidably matched with the connecting hole 41 can also be disassembled and assembled, and thus the maintenance, replacement and adjustment operations of the supporting structure 30 can be facilitated.

[0083] Please refer to Figures 1 to 3 , in some embodiments, a threaded connection section 42 is formed on the outer peripheral wall of the connecting structure 40, and a threaded hole 11 is formed in the main body structure 10, and the threaded connection section 42 is screwed into the threaded hole 11.

[0084] It can be understood that the connecting structure 40 can be a rod-shaped structural member with a cylindrical outer shape.

[0085] A threaded connection section 42 is formed on the outer peripheral wall of the connecting structure 40; optionally, the threaded connection section 42 can be formed on a section of the connecting structure 40 facing the first direction G; or, the threaded connection section 42 can be formed on a section of the connecting structure 40 facing away from the first direction G; or, the threaded connection section 42 is formed on the entire outer peripheral wall of the connecting structure 40.

[0086] With such a setting, the connecting structure 40 can be screwed into the threaded hole 11 of the main body structure 10 through the threaded connection section 42. Thus, the connecting structure 40 can adjust its position in the first direction G according to the threaded connection section 42, and further can adjust the position of the supporting structure 30 in the first direction G to improve its scope of application.

[0087] Please refer to Figures 1 to 3 , in some embodiments, a fastening nut 60 is screwed on the part of the threaded connection section 42 extending out of the threaded hole 11, and the fastening nut 60 abuts against the main body structure 10.

[0088] Optionally, the threaded connection section 42 can extend out of the threaded hole 11 along the first direction G; thus, the threaded connection section 42 is connected with a fastening nut 60 on the side of the main body structure 10 facing the first direction G, and the fastening nut 60 is screwed to abut against the main body structure 10 to achieve the fastening effect on the threaded connection section 42.

[0089] Or, the threaded connection section 42 can extend out of the threaded hole 11 in a direction opposite to the first direction G; thus, the threaded connection section 42 is connected with a fastening nut 60 on the side of the main body structure 10 opposite to the first direction G, and the fastening nut 60 is screwed to abut against the main body structure 10 to achieve the fastening effect on the threaded connection section 42.

[0090] Or, the threaded connection section 42 can extend out of the threaded hole 11 at opposite ends of the threaded hole 11 respectively, and the threaded connection section 42 is connected with fastening nuts 60 on both the side of the main body structure 10 facing the first direction G and the side opposite to the first direction G.

[0091] With such a setting, the fastening nut 60 can be screwed on the threaded connection section 42 and abut against the main body structure 10 to achieve the purpose of locking the connecting structure 40 to the main body structure 10; meanwhile, by rotating the nut away from the main body structure 10, the connecting structure 40 can adjust its position relative to the main body structure 10 by rotating the threaded connection section 42, and further can adjust the abutting range of the abutting end 31 of the supporting structure 30; and after the position adjustment is completed, the fastening nut 60 is rotated to abut against the main body structure 10 to re-lock the connecting structure 40.

[0092] Please refer to Figures 1 to 3 , in some embodiments, a buffer structure 70 is provided on the abutting end 31.

[0093] It can be understood that the abutting end 31 is used for abutting and contacting materials such as adapter plates; by providing a buffer structure 70 on the abutting end 31 and using the buffer structure 70 to replace the direct contact of the abutting end 31, the hard contact between the abutting end 31 and the adapter plate can be improved to soft contact to reduce the collision damage to materials such as adapter plates.

[0094] Among them, the buffer structure 70 includes, but is not limited to, soft material parts with buffer performance such as polyurethane elastomer (urethane rubber), rubber, silica gel, etc.

[0095] Optionally, the buffer structure 70 can be disposed on the end surface of the abutting end 31 facing the first direction G; or, the buffer structure 70 can form a wrap-around coverage of the abutting end 31, and the buffer structure 70 can wrap the abutting end 31 and a part of the support structure 30 to achieve a more comprehensive buffer protection.

[0096] With such a setting, by providing the buffer structure 70 on the abutting end 31, the buffer structure 70 can contact the material instead of the abutting end 31 to reduce the damage caused to the material; at the same time, the buffer structure 70 contacting the material instead of the abutting end 31 can also reduce the wear of the support structure 30, so as to reduce the probability of particulate matter entering the produced battery due to the wear of the support structure 30.

[0097] Please refer to Figure 4 , in some embodiments, an assembly hole 12 is formed on the main body structure 10, and the support structure 30 is inserted into the assembly hole 12, and the support structure 30 is in sliding fit with the assembly hole 12.

[0098] Among them, the assembly hole 12 can be, but is not limited to, a circular hole, a rectangular hole or other polygonal holes; thus, the connection structure 40 can be, but is not limited to, a cylindrical top post, a prismatic top post, etc.

[0099] With such a setting, the support structure 30 can slide in the assembly hole 12 so that the support structure 30 abuts against the materials stacked below the grabbed material, thereby achieving the purpose of separating the stacked materials and reducing the probability of the stacked materials being mis-grabbed due to overlapping of the stacked sheets.

[0100] Please refer to Figure 4 , in some embodiments, a second elastic member 80 is disposed in the assembly hole 12, and in the first direction G, the opposite ends of the second elastic member 80 respectively abut against the support structure 30 and the inner wall of the hole of the assembly hole 12.

[0101] Among them, the second elastic member 80 is an elastic structural member; the second elastic member 80 includes, but is not limited to, a spring, a tension spring, an elastic gasket, etc. One end of the second elastic member 80 abuts against the support structure 30 (for example, it can abut against the end of the support structure 30 facing away from the first direction G, or it can abut against the circumferential side wall of the support structure 30), and the opposite end of the second elastic member 80 abuts against the inner wall of the hole of the assembly hole 12 (for example, the inner side wall of the hole of the assembly hole 12); thus, the second elastic member 80 can act on the support structure 30 and keep the support structure 30 in a state of being abutted, that is, when the support structure 30 is not subjected to other external forces, it can maintain the initial state of extending out of the connection hole 41 to the limit state.

[0102] Next, the grasping device 100 of the present application will be described in detail according to specific embodiments.

[0103] Please refer to Figures 1 to 3 , in this embodiment, the grasping device 100 includes a main body structure 10, a grasping structure 20, a connecting structure 40, and a supporting structure 30. The grasping structure 20 can be fixedly installed on the main body structure 10 through fasteners; the grasping structure 20 has a grasping end 21 facing the first direction G. In this embodiment, the grasping end 21 can be a suction cup structure.

[0104] Among them, the connecting structure 40 can adopt a strut. One end of the strut facing the first direction G is provided with a connection hole 41, and a threaded connection section 42 is provided on the circumferential side wall of the strut. A threaded hole 11 is also provided on the main body structure 10; the strut can be screwed into the threaded hole 11 through the threaded connection section 42. Optionally, the threaded connection section 42 can extend out to the outside from the opposite ends of the threaded hole 11 respectively; the grasping device 100 further includes a fastening nut 60. A fastening nut 60 can be screwed on the part of the threaded connection section 42 extending out of the threaded hole 11 towards the first direction G, and the fastening nut 60 is abutted against the main body structure 10. At the same time, a nut is also screwed on the part of the threaded connection section 42 extending out of the threaded hole 11 in the direction opposite to the first direction G, and the fastening nut 60 is abutted against the main body structure 10. Thus, the strut can be locked by the fastening nuts 60 at both ends, and the strut can be unlocked by unscrewing the nuts, and the position of the strut in the first direction G can be adjusted by rotating the threaded connection section 42.

[0105] The supporting structure 30 can adopt a top column. One end of the top column is inserted into the connection hole 41, and the top column is slidably matched with the connection hole 41. At the same time, a first elastic member 50 (such as a spring) can be arranged in the connection hole 41. One end of the first elastic member 50 is abutted against the inner wall of the connection hole 41, and the opposite end of the first elastic member 50 is abutted against the top column; thus, the first elastic member 50 can act on the top column and keep the top column in a butted state, that is, when the top column is not affected by other external forces, it can maintain the initial state of extending out of the connection hole 41 to the limit state.

[0106] A buffer structure 70, such as urethane rubber, can be arranged on the abutting end 31 of the supporting structure 30 facing the first direction G; the urethane rubber is wrapped around the abutting end 31 to form a covering on the abutting end 31.

[0107] Thus, when the gripping end 21 grips the adapter plate, the urethane rubber wrapped around the abutting end 31 can abut against the adapter plate below the gripped adapter plate; and the ejector pin can be inserted into the connecting hole 41 and compress the first elastic member 50 for adaptive adjustment. After the gripping end 21 grips the adapter plate, the main body structure 10 can drive the gripping end 21 to move in a direction away from the first direction G to grip the adapter plate; at this time, the ejector pin can move relative to the main body structure 10 in the first direction G under the action of the elastic restoring force of the first elastic member 50, so that the urethane rubber can continue to abut against the adapter plate below for a period of time. Thus, the gripped adapter plate and the adjacent stacked adapter plates can be separated.

[0108] Please refer to Figure 5 , in a second aspect, an embodiment of the present application further provides a battery production line 1000, including a driving device 200 and the gripping device 100 as described above, and the driving device 200 is drivingly connected to the gripping device 100.

[0109] The battery production line provided by the embodiment of the present application includes the above-mentioned gripping device 100. On the basis that the probability of mis-gripping of the above-mentioned gripping device 100 is relatively low, the production process of the battery production line is smoother.

[0110] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
