Description

Technical Field

[0001] This utility model belongs to the field of workpiece handling technology, and more specifically, it relates to a clamping component and a handling mechanism. Background Technology

[0002] When transferring workpieces, a clamping assembly is typically used to grip the workpiece first, and then a displacement assembly drives the clamping assembly to move the workpiece. However, when the workpiece is in different positions, the clamping assembly cannot determine the clamping height of the workpiece when clamping it at different positions, thus failing to guarantee that the workpiece can accurately contact the supporting plane when unloading it. Utility Model Content

[0003] The present invention provides a clamping component and a conveying mechanism, which can ensure that the workpiece is in contact with the supporting plane when the workpiece is unloaded.

[0004] The technical solution adopted by this utility model is a clamping component, including:

[0005] Base;

[0006] A clamping structure includes a first mounting member, a second mounting member, a first clamping member, and a second clamping member. The first and second mounting members are horizontally disposed opposite each other on the base, and are capable of moving closer to or further away from each other. The first clamping member is disposed on the side of the first mounting member closer to the second mounting member, and the second clamping member is disposed on the side of the second mounting member closer to the first mounting member.

[0007] A first buffer structure and a second buffer structure are provided. The first buffer structure is connected between the first clamping member and the first mounting member. The first buffer structure allows the first clamping member to move vertically on the first mounting member. The second buffer structure is connected between the second clamping member and the second mounting member. The second buffer structure allows the second clamping member to move vertically on the second mounting member.

[0008] In other words, in the clamping assembly of this application, a first mounting member and a second mounting member are arranged opposite each other on the base in a horizontal direction. A first clamping member is provided on the side of the first mounting member closer to the second mounting member, and a second clamping member is provided on the side of the second mounting member closer to the first mounting member. The first mounting member and the second mounting member can move closer to or further away from each other, so that the first clamping member and the second clamping member can cooperate to clamp or release the workpiece. In addition, a first buffer structure is connected between the first clamping member and the first mounting member. The first buffer structure allows the first clamping member to move vertically on the first mounting member, and the second clamping member and the first mounting member can move vertically on the second mounting member. A second buffer structure is connected between the second mounting components. The second buffer structure allows the second clamping component to move vertically on the second mounting component. In this way, when the clamped workpiece needs to be unloaded onto the support surface of the workpiece, the clamping assembly can move the entire workpiece vertically downward a certain distance to ensure that the workpiece can contact the support surface. After the workpiece contacts the support surface, the first clamping component can move vertically upward relative to the first mounting component, and the second clamping component can move vertically upward relative to the second mounting component, thereby achieving buffering after the workpiece contacts the support surface and avoiding crushing the workpiece or damaging the clamping assembly.

[0009] Optionally, the first buffer structure includes a first sliding member and a first stop member. The first clamping member is disposed on the first mounting member via the first sliding member, and the first stop member is disposed on the first mounting member and can abut against it when the first clamping member moves vertically downward, so as to prevent the first clamping member from disengaging from the first mounting member.

[0010] Optionally, the first clamping member is provided with a first limiting hole, the first stop member is located in the first limiting hole, and can move vertically within the first limiting hole and can move to abut against the inner wall of the first limiting hole.

[0011] Optionally, the first buffer structure further includes a first buffer elastic element, which is disposed in the first limiting hole, and both ends of the first buffer elastic element are respectively connected to the first stop and the inner wall of the first limiting hole, so as to provide elastic buffering when the first clamping member moves vertically upward.

[0012] Optionally, the first clamping member has a first opening at the end away from the workpiece being clamped, and the first opening communicates with the first limiting hole;

[0013] The first stop member has a first through hole extending vertically through it, and one end of the first buffer elastic member is connected to the inner wall of the first limiting hole through the first through hole; and

[0014] The first buffer structure further includes a first clamping member, which is disposed on the first stop member through the first opening to restrict the other end of the first buffer elastic member within the first through hole.

[0015] Optionally, a first retaining groove is provided on the inner wall of the first limiting hole, and one end of the first buffer elastic member is retained in the first retaining groove.

[0016] Optionally, the clamping structure further includes a first clamping drive member, which is motive-connected to the first mounting member to drive the first mounting member closer to or away from the second mounting member; and / or

[0017] The clamping structure further includes a second clamping drive member, which is driven to connect with the second mounting member to drive the second mounting member to move closer to or away from the first mounting member.

[0018] Optionally, it also includes a clamping structure, which includes a pressure roller and a clamping elastic element. The pressure roller is disposed on a base between the first clamping member and the second clamping member through the clamping elastic element, so the pressure roller acts on the workpiece clamped by the first clamping member and the second clamping member.

[0019] Optionally, the clamping structure further includes a clamping drive and a connecting member. The clamping drive is disposed on the base, and the pressure roller is disposed on the connecting member through the clamping elastic member. The clamping drive and the connecting member are driven to drive the connecting member to move in the vertical direction.

[0020] A conveying mechanism includes a displacement component and the clamping component, the displacement component being drivenly connected to the base to drive the base to move. Attached Figure Description

[0034] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0035] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0036] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the clamping components and conveying mechanisms or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In some descriptions of utility models, "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] This application provides a clamping assembly that can be applied to a conveying mechanism to facilitate the picking and placing of workpieces. For example, the workpiece can be a battery cell, and the conveying mechanism can pick up and place the battery cell using the clamping assembly during the conveying process.

[0039] See Figure 1 A clamping assembly includes a base 100, a clamping structure 200, a first buffer structure 300, and a second buffer structure 400. The clamping structure 200 is disposed on the base 100 and is used to clamp or release a workpiece 600. The first buffer structure 300 and the second buffer structure 400 provide buffering when the clamping structure 200 places the workpiece 600 on a support surface, so as to ensure that the workpiece 600 can contact the support surface, while avoiding damage to the workpiece 600 or the clamping assembly.

[0040] Furthermore, the clamping structure 200 may include a first mounting member 210, a second mounting member 220, a first clamping member 230, and a second clamping member 240. The first mounting member 210 and the second mounting member 220 are arranged opposite each other on the base 100 in a horizontal direction, and the first mounting member 210 and the second mounting member 220 can move closer to or further away from each other. The first clamping member 230 is disposed on the side of the first mounting member 210 closer to the second mounting member 220, and the second clamping member 240 is disposed on the side of the second mounting member 220 closer to the first mounting member 210.

[0041] Specifically, when it is necessary to clamp the workpiece 600, the first mounting member 210 and the second mounting member 220 can move closer to each other, thereby causing the first clamping member 230 and the second clamping member 240 to move closer to each other to clamp the workpiece 600. When it is necessary to release the workpiece 600, the first mounting member 210 and the second mounting member 220 can move away from each other, thereby causing the first clamping member 230 and the second clamping member 240 to move away from each other to release the workpiece 600.

[0042] Furthermore, a first buffer structure 300 is connected between the first clamping member 230 and the first mounting member 210, and the first buffer structure 300 allows the first clamping member 230 to move vertically on the first mounting member 210. A second buffer structure 400 is connected between the second clamping member 240 and the second mounting member 220, and the second buffer structure 400 allows the second clamping member 240 to move vertically on the second mounting member 220.

[0043] Specifically, when the clamping assembly feeds the workpiece 600 vertically to the support surface of the workpiece 600, the clamping assembly can continue to move vertically downward a certain distance to ensure that the workpiece 600 can contact the support surface. After the workpiece 600 contacts the support surface, the first buffer structure 300 can cause the first clamping member 230 to move vertically upward relative to the first mounting member 210 for buffering, and the second buffer structure 400 can cause the second clamping member 240 to move vertically upward relative to the second mounting member 220 for buffering. Thus, the first clamping member 230 and the second clamping member 240 can buffer the workpiece 600 during the feeding process to the support surface, avoiding crushing the workpiece 600 or damaging the clamping assembly.

[0044] In other words, in the clamping assembly of this application, a first mounting member 210 and a second mounting member 220 are arranged opposite each other in the horizontal direction on the base 100. A first clamping member 230 is provided on the side of the first mounting member 210 near the second mounting member 220, and a second clamping member 240 is provided on the side of the second mounting member 220 near the first mounting member 210. The first mounting member 210 and the second mounting member 220 can move closer to or further away from each other, so that the first clamping member 230 and the second clamping member 240 can cooperate to clamp or release the workpiece 600. In addition, a first buffer structure 300 is connected between the first clamping member 230 and the first mounting member 210. The first buffer structure 300 allows the first clamping member 230 to move vertically on the first mounting member 210. A second buffer structure 400 is connected between the clamping member 240 and the second mounting member 220. The second buffer structure 400 allows the second clamping member 240 to move vertically on the second mounting member 220. Thus, when the clamped workpiece 600 needs to be unloaded onto the support surface supporting the workpiece 600, the clamping assembly can move the workpiece 600 vertically downward a certain distance to ensure that the workpiece 600 can contact the support surface. After the workpiece 600 contacts the support surface, the first clamping member 230 can move vertically upward relative to the first mounting member 210 and the second clamping member 240 can move vertically upward relative to the second mounting member 220, thereby achieving buffering after the workpiece 600 contacts the support surface and preventing damage to the workpiece 600 or the clamping assembly.

[0045] See Figure 2 and Figure 3 The first buffer structure 300 may include a first sliding member 310 and a first stop member 320. The first clamping member 230 is disposed on the first mounting member 210 via the first sliding member 310 so that the first clamping member 230 can move vertically relative to the first mounting member 210. The first stop member 320 is disposed on the second mounting member 220 and can abut against it when the first clamping member 230 moves vertically downward to prevent the first clamping member 230 from disengaging from the first mounting member 210.

[0046] Understandably, since the first clamping member 230 can move vertically relative to the first mounting member 210, it can move vertically upwards or downwards. For example, under the influence of gravity, the first clamping member 230 can move vertically downwards. When the workpiece 600 clamped by the first clamping member 230 is subjected to the reaction force of the supporting surface, the first clamping member 230 can move vertically upwards relative to the first mounting member 210 for buffering. In the above embodiment, to prevent the first clamping member 230 from detaching from the first mounting member 210 when it moves vertically downwards under the influence of gravity, the first stop member 320 can stop the first clamping member 230 during its vertical downward movement.

[0047] The first sliding member 310 can be a slide rail. The slide rail can facilitate the vertical movement of the first clamping member 230 relative to the first mounting member 210, and can also guide the first clamping member 230 when it moves vertically.

[0048] Furthermore, in one embodiment, in order to facilitate the use of a first stop 320 on the first mounting member 210 to stop the first clamping member 230, a first limiting hole 231 may be provided on the first clamping member 230. The first stop 320 is located in the first limiting hole 231 and can move vertically within the first limiting hole 231 and can move to abut against the inner wall of the first limiting hole 231, thereby limiting the movement distance of the first stop 320 within the first limiting hole 231.

[0049] It is understood that when the first clamping member 230 moves vertically relative to the first mounting member 210, the first stop member 320 can move relative to the first clamping member 230 within the first limiting hole 231. By abutting against the inner wall of the first limiting hole 231, the movement distance of the first stop member 320 within the first limiting hole 231 can be limited, thereby limiting the vertical movement distance of the first clamping member 230 relative to the first mounting member 210, and thus controlling the buffer distance of the first clamping member 230.

[0050] For example, in one embodiment, when the first clamping member 230 moves vertically upward relative to the first mounting member 210, the first stop member 320 can move vertically downward within the first limiting hole 231. After the first clamping member 230 moves to a predetermined position, the lower surface of the first stop member 320 can abut against the inner wall of the first limiting hole 231, thereby limiting the buffering distance. When the first clamping member 230 moves vertically downward relative to the first mounting member 210, the first stop member 320 can move vertically upward within the first limiting hole 231. After the first clamping member 230 moves to a predetermined position, the upper surface of the first stop member 320 can abut against the inner wall of the first limiting hole 231, thereby preventing the first clamping member 230 from detaching from the first mounting member 210.

[0051] Furthermore, the first buffer structure 300 may also include a first buffer elastic member 330, which is disposed in the first limiting hole 231, and the two ends of the first buffer elastic member 330 are respectively connected to the first stop member 320 and the inner wall of the first limiting hole 231, so as to provide elastic buffering when the first clamping member 230 moves vertically upward.

[0052] It is understood that by connecting the first buffer elastic element 330 between the inner wall of the first stop 320 and the first limiting hole 231, the first clamping member 230 can be elastically buffered when moving vertically upward, thereby improving the stability of the movement of the first clamping member 230. The first buffer elastic element 330 can be a spring.

[0053] See Figure 3 The first clamping member 230 may also have a first opening 232 at the end away from the clamped workpiece 600. The first opening 232 communicates with the first limiting hole 231. The first stop member 320 has a first through hole 340 extending vertically through it. One end of the first buffer elastic member 330 is connected to the inner wall of the first limiting hole 231 through the first through hole 340. The first buffer structure 300 also includes a first pressing member 350, which is disposed on the first stop member 320 through the first opening 232 to restrict the other end of the first buffer elastic member 330 within the first through hole 340. It can be understood that the above structure facilitates the installation of the first buffer elastic member 330.

[0054] During installation, the first clamping member 230 can be placed on the first stop member 320 through the first limiting hole 231, and the first clamping member 230 can be stabilized on the first stop member 320 by the resistance of the first stop member 320. Then, the first buffer elastic member 330 is placed in the first through hole 340, and one end of the first buffer elastic member 330 is connected to the inner wall of the first limiting hole 231 (for example, it can be connected by abutting). Then, the first pressing member 350 is placed on the first stop member 320 through the first opening 232 to cover the first through hole 340, thereby restricting the other end of the first buffer elastic member 330 in the first through hole 340, thus realizing the connection of the first buffer elastic member 330.

[0055] Furthermore, a first retaining groove 233 may be provided on the inner wall of the first limiting hole 231, and one end of the first buffer elastic member 330 is retained in the first retaining groove 233 so that the first buffer elastic member 330 can be stably placed on the inner wall of the first limiting hole 231, which facilitates the connection of the first buffer elastic member 330.

[0056] Alternatively, in one embodiment, the second buffer structure 400 may be the same as the first buffer structure 300.

[0057] For example, the second buffer structure 400 may include a second slider and a second stop. The second clamping member 240 is disposed on the second mounting member 220 via the second slider so that the second clamping member 240 can move vertically relative to the second mounting member 220. The second stop is disposed on the second mounting member 220 and can abut against it when the second clamping member 240 moves vertically downward to prevent the second clamping member 240 from disengaging from the second mounting member 220.

[0058] It is understandable that, since the second clamping member 240 can move vertically relative to the second mounting member 220, the second clamping member 240 can move vertically upward or vertically downward. For example, the second clamping member 240 can move vertically downward under the action of gravity, while when the workpiece 600 clamped by the second clamping member 240 is subjected to the reaction force of the supporting surface, the second clamping member 240 can move vertically upward relative to the second mounting member 220 for buffering. In the above embodiment, in order to prevent the second clamping member 240 from detaching from the second mounting member 220 when the second clamping member 240 moves vertically downward under the action of gravity, the second stop member can stop the second clamping member 240 during the vertical downward movement.

[0059] The second sliding member can be a slide rail. The slide rail can facilitate the vertical movement of the second clamping member 240 relative to the second mounting member 220, and can also guide the second clamping member 240 when it moves vertically.

[0060] Furthermore, in one embodiment, in order to facilitate the setting of a second stop on the second mounting member 220 to stop the second clamping member 240, a second limiting hole may be provided on the second clamping member 240. The second stop is located in the second limiting hole and can move vertically in the second limiting hole and can move to abut against the inner wall of the second limiting hole, thereby limiting the movement distance of the second stop in the second limiting hole.

[0061] It is understood that when the second clamping member 240 moves vertically relative to the second mounting member 220, the second stop member can move within the second limiting hole relative to the second clamping member 240. By abutting against the inner wall of the second limiting hole within the second limiting hole, the movement distance of the second stop member within the second limiting hole can be limited, thereby limiting the distance of the second clamping member 240 moving vertically relative to the second mounting member 220, and thus controlling the buffer distance of the second clamping member 240.

[0062] For example, in one embodiment, when the second clamping member 240 moves vertically upward relative to the second mounting member 220, the second stop member can move vertically downward within the second limiting hole. After the second clamping member 240 moves to a predetermined position, the lower surface of the second stop member can abut against the inner wall of the second limiting hole, thereby limiting the buffer distance. When the second clamping member 240 moves vertically downward relative to the second mounting member 220, the second stop member can move vertically upward within the second limiting hole. After the second clamping member 240 moves to a predetermined position, the upper surface of the second stop member can abut against the inner wall of the second limiting hole, thereby preventing the second clamping member 240 from disengaging from the second mounting member 220.

[0063] Furthermore, the second buffer structure 400 may also include a second buffer elastic member, which is disposed in the second limiting hole, and both ends of the second buffer elastic member are respectively connected to the second stop and the inner wall of the second limiting hole, so as to provide elastic buffering when the second clamping member 240 moves vertically upward.

[0064] It is understood that by connecting a second buffer elastic element between the inner walls of the second stop and the second limiting hole, the second clamping member 240 can be elastically buffered when moving vertically upward, thereby improving the stability of the movement of the second clamping member 240. The second buffer elastic element can be a spring.

[0065] See Figure 2 The second clamping member 240 may also have a second opening at the end furthest from the clamping workpiece 600. The second opening communicates with the second limiting hole. A second through hole is provided vertically through the second stop member. One end of the second buffer elastic member is connected to the inner wall of the second limiting hole through the second through hole. The second buffer structure 400 also includes a second clamping member, which is disposed on the second stop member through the second opening to restrict the other end of the second buffer elastic member within the second through hole. It can be understood that the above structure facilitates the installation of the second buffer elastic member.

[0066] During installation, the second clamping member 240 can be placed on the second stop member through the second limiting hole, and the second clamping member 240 can be stabilized on the second stop member by the resistance of the second stop member. Then, the second buffer elastic member is placed in the second through hole, and one end of the second buffer elastic member is connected to the inner wall of the second limiting hole (for example, it can be connected by abutting). Then, the second clamping member is placed on the second stop member through the second opening to cover the second through hole, thereby restricting the other end of the second buffer elastic member in the second through hole, thus realizing the connection of the second buffer elastic member.

[0067] Furthermore, a second retaining groove may be provided on the inner wall of the second limiting hole, and one end of the second buffer elastic member is retained in the second retaining groove so that the second buffer elastic member can be stably placed on the inner wall of the second limiting hole, which facilitates the connection of the second buffer elastic member.

[0068] See Figure 1 In one embodiment, the clamping structure 200 may further include a first clamping drive 250, which is motive-connected to the first mounting member 210 to drive the first mounting member 210 closer to or further away from the second mounting member 220. Specifically, the first clamping drive 250 can drive the first clamping member 230 closer to or further away from the second clamping member 240 on the second mounting member 220 via the first mounting member 210. The first clamping drive 250 may be a cylinder.

[0069] In one embodiment, the clamping structure 200 may further include a second clamping drive 260, which is motive-connected to the second mounting member 220 to drive the second mounting member 220 closer to or further away from the first mounting member 210. Specifically, the second clamping drive 260 can drive the second clamping member 240 closer to or further away from the first clamping member 230 on the first mounting member 210 via the second mounting member 220. The second clamping drive 260 may be a cylinder.

[0070] Of course, in one embodiment, the first clamping drive member 250 and the second clamping drive member 260 can operate synchronously, so that the first clamping member 230 and the second clamping member 240 can move closer to or further away from each other.

[0071] Optionally, see Figure 1 A first insulating block 270 may be provided at the end of the first clamping member 230 away from the first limiting hole 231, and the first clamping member 230 contacts the workpiece 600 through the first insulating block 270.

[0072] A second insulating block 280 may be provided at the end of the second clamping member 240 away from the second limiting hole, and the second clamping member 240 contacts the workpiece 600 through the second insulating block 280.

[0073] See Figure 4 In one embodiment, the clamping assembly may further include a clamping structure 500, which acts on the workpiece 600 clamped by the first clamping member 230 and the second clamping member 240.

[0074] See Figure 5 The clamping structure 500 includes a pressure roller 510 and a clamping elastic element 520. The pressure roller 510 is disposed on the base 100 between the first clamping member 230 and the second clamping member 240 through the clamping elastic element 520. The pressure roller 510 acts on the workpiece 600 clamped by the first clamping member 230 and the second clamping member 240 to shape the workpiece 600.

[0075] Furthermore, the clamping structure 500 may also include a clamping drive 530 and a connector 540. The clamping drive 530 is disposed on the base 100, and the pressure roller 510 is disposed on the connector 540 through the clamping elastic member 520. The clamping drive 530 and the connector 540 are driven to move the connector 540 in the vertical direction.

[0076] Specifically, the clamping drive 530 can drive the clamping elastic element 520 and the pressure roller 510 connected to the clamping elastic element 520 to act on the workpiece 600 through the connecting element 540, thereby shaping the workpiece 600. The clamping drive 530 can be a cylinder.

[0077] Furthermore, this application also provides a conveying mechanism, including a displacement component and a gripping component as described in this application embodiment. The displacement component is drivenly connected to the base 100 to drive the base 100 to move.

[0078] Understandably, when the base 100 moves, the entire gripping assembly can move, thereby allowing the workpiece 600 to be transferred. The displacement mechanism can be a robotic arm or other multi-axis moving platform.

[0079] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of some utility models should be included within the protection scope of some utility models.
