[0002] With the rapid development of the new energy industry, the automated production equipment for power batteries is constantly updated to meet the market requirements for production speed and quality.

[0003] The related art discloses a loading mechanism for clamping and flipping power batteries. However, due to the unreasonable setting of this loading mechanism, the flipping torque is relatively large, which affects the flipping positioning accuracy. Utility Model Content

[0004] This application provides a loading mechanism, which can improve the problem that the flipping positioning accuracy is affected by the relatively large torque during flipping.

[0005] The technical solution adopted by this application is: to provide a loading mechanism, including a rotating assembly and a clamping assembly. The rotating assembly includes a first driving member and a rotating shaft, the first driving member is drivingly connected to the rotating shaft, and the first driving member can drive the rotating shaft to rotate; the clamping assembly includes a second driving member, the second driving member is arranged on the rotating shaft, the clamping assembly further includes two clamping members, the two clamping members are arranged on the rotating shaft and / or the second driving member, the second driving member is drivingly connected to the two clamping members, and the second driving member can drive the two clamping members to move relatively closer or farther apart; the two clamping members are located on one side of a radial direction of the rotating shaft. Define the axial direction of the rotating shaft as the first direction, and define the radial direction corresponding to the side where the two clamping members are located on the rotating shaft as the second direction; the first direction and the second direction intersect to form a plane, and each clamping member is symmetric about this plane.

[0006] Further, the first driving member is set as a driving motor, and the rotating shaft of the driving motor is coaxially arranged with the rotating shaft.

[0007] Further, the two clamping members are movably arranged on the rotating shaft along the axial direction of the rotating shaft.

[0008] Further, the second driving member is located on one side of a radial direction of the rotating shaft, and the two clamping members are located on the other side of the radial direction of the rotating shaft; or, the two clamping members and the second driving member are located on the same side of a radial direction of the rotating shaft.

[0009] Further, the second driving member is symmetric about the plane formed by the intersection of the first direction and the second direction.

[0010] Further, the clamping member includes a clamping jaw and a connecting portion. The connecting portion is drivingly connected to the second driving member. The connecting portion is slidably disposed on the rotating shaft along the axial direction of the rotating shaft. The clamping jaw is elastically movable along the second direction on the connecting portion.

[0011] Further, the clamping assembly further includes two limiting members. Each limiting member is disposed on one of the clamping members. The two limiting members are oppositely disposed along the axial direction of the rotating shaft. Each limiting member protrudes with a limiting block in the direction of approaching the other limiting member along the axial direction of the rotating shaft. The limiting block is provided with a limiting groove.

[0012] Further, the feeding mechanism further includes a third driving member and a bracket. The first driving member is disposed on the bracket. The rotating shaft is rotatably disposed on the bracket. The third driving member is drivingly connected to the bracket. The third driving member can drive the bracket to move up and down.

[0015] In the feeding mechanism provided by the present application, the second driving member of the clamping assembly drives the two clamping members to move relatively closer to clamp the workpiece. When the second driving member drives the two clamping members to move relatively away, it can be used to release the workpiece. In this way, the picking and placing of the workpiece are realized. The first driving member of the rotating assembly drives the rotating shaft to rotate. The rotating shaft can directly or indirectly drive the clamping assembly to rotate synchronously through the structure of the second driving member, achieving the flipping effect of the clamping assembly, and cooperating with the picking and placing operation of the clamping assembly, so as to realize the effects of flipping and picking and placing the workpiece.

[0016] Among them, the two clamping members can be disposed on the second driving member, or can be disposed on the rotating shaft. Of course, they can also be disposed on the second driving member and the rotating shaft at the same time. Thus, when the rotating shaft rotates, the two clamping members can be driven to rotate synchronously to achieve the flipping effect.

[0017] Further, the first direction and the second direction intersect to form a plane, and the structure of each clamping member is symmetric about this plane. It can be understood that the axis of the rotation shaft and the center of gravity of each clamping member are both on this plane. With such a setting, it is helpful to improve the overall rotational consistency of the rotation shaft and the two clamping members, thereby contributing to improving the accuracy of rotational control and avoiding the increase of the rotational lever arm due to the deviation of the center of gravity of the rotation shaft and the two clamping members, which may lead to an increase in torque and affect the driving and positioning accuracy.

[0029] Please refer to Figure 1 , and now the feeding mechanism 10 provided in the embodiment of the present application will be described. The feeding mechanism 10 provided in the embodiment of the present application includes a bracket 101, a rotating assembly 102, and a clamping assembly 103. The rotating assembly 102 includes a first driving member 1021 and a rotating shaft 1022. The first driving member 1021 and the rotating shaft 1022 are respectively disposed on the bracket 101. The first driving member 1021 is drivingly connected to the rotating shaft 1022, and the first driving member 1021 can drive the rotating shaft 1022 to rotate. The clamping assembly 103 includes a second driving member 1031. The second driving member 1031 is disposed on the rotating shaft 1022. The clamping assembly 103 further includes two clamping members 1033 disposed opposite to each other. The second driving member 1031 is drivingly connected to the two clamping members 1033, and the second driving member 1031 can drive the two clamping members 1033 to move relatively closer or farther away.

[0030] In the feeding mechanism 10 provided in the embodiment of the present application, the second driving member 1031 of the clamping assembly 103 drives the two clamping members 1033 to move relatively closer to clamp the workpiece; and when the second driving member 1031 drives the two clamping members 1033 to move relatively farther away, it can be used to release the workpiece, thus realizing the picking and placing of the workpiece. The first driving member 1021 of the rotating assembly 102 drives the rotating shaft 1022 to rotate, and the rotating shaft 1022 can drive the clamping assembly 103 to rotate synchronously, achieving the flipping effect of the clamping assembly 103, and cooperating with the picking and placing operation of the clamping assembly 103, thereby realizing the effect of flipping and picking and placing the workpiece.

[0031] Among them, the rotating shaft 1022 in the embodiments of the present application can be understood as a rod-shaped structure, specifically a rectangular rod shape or a cylindrical shape, or a prism with other cross-sectional shapes, etc., as long as it can meet the requirement of uniform circumferential torque for the self-rotation of the rotating shaft 1022. The two clamping members 1033 can be arranged on the second driving member 1031, or can be arranged on the rotating shaft 1022. Of course, they can also be arranged on the second driving member 1031 and the rotating shaft 1022 at the same time. Thus, when the rotating shaft 1022 rotates, it can drive the two clamping members 1033 to rotate synchronously to achieve a flipping effect.

[0032] The two clamping members 1033 are located on one side of a radial direction of the rotating shaft 1022. Define the axial direction of the rotating shaft 1022 as the first direction, denoted as X, and define the radial direction corresponding to the side of the second driving member 1031 and the two clamping members 1033 on the rotating shaft 1022 side as the second direction, denoted as Y. The first direction and the second direction are perpendicular to each other; the first direction and the second direction intersect to form a plane, denoted as M. The structure of each clamping member 1033 in the above embodiments is symmetric about this plane.

[0033] In the embodiments of the present application, the plane M specifically takes the axis passing through the rotating shaft 1022 as an example. That is, it can be understood that the axis of the rotating shaft 1022 and the center of gravity of each clamping member 1033 are both on the plane M. With such a setting, it can help to improve the overall rotational consistency of the structure of the rotating shaft 1022 and the two clamping members 1033, and further help to improve the accuracy of controlling rotation, and avoid increasing the rotational lever arm due to the deviation of the center of gravity of the structure of the rotating shaft 1022 and the two clamping members 1033, thereby increasing the torque and affecting the driving and positioning accuracy.

[0034] Furthermore, the structure of the second driving member 1031 in the above embodiments can also be symmetric about this plane, that is, the axis of the rotating shaft 1022 and the center of gravity of the second driving member 1031 are both on the plane M. With such a setting, it can help to improve the overall rotational consistency of the structure of the rotating shaft 1022 and the second driving member 1031, and further help to further improve the accuracy of controlling rotation, and avoid increasing the rotational lever arm of the rotating shaft 1022 due to the deviation of the center of gravity of the structure of the second driving member 1031 from the plane M, thereby increasing the torque and affecting the driving and positioning accuracy.

[0035] Furthermore, the feeding mechanism 10 may further include a third driving member 104. Taking the clamping jaw 10331 as an example, when it is rotated to the vertical state, it is used to clamp the workpiece. The third driving member 104 is drivingly connected to the bracket 101, and the third driving member 104 can drive the bracket 101 to move up and down.

[0036] The third driving member 104 drives the bracket 101 to descend and stops when the jaw 10331 can pick up the workpiece. In the embodiment of the present application, the jaw 10331 is elastically connected to the connecting portion 10332 in the vertical direction at this time, so as to avoid collision damage or workpiece damage during the approach of the jaw 10331 and the workpiece. Then, the second driving member 1031 drives the two clamping members 1033 to move relatively closer to each other, so that the two jaws 10331 pick up the workpiece. After the picking is completed, the third driving member 104 can be controlled to drive the bracket 101 to rise and the first driving member 1021 to drive the rotating shaft 1022 to rotate, so as to realize the transfer and loading of the workpiece.

[0037] It should be noted that the rotation assembly 102 and the corresponding clamping assembly 103 in the embodiment of the present application can be provided in one group or multiple groups, which is specifically determined according to actual needs and is not limited.

[0038] The first driving member 1021 in the above embodiment takes a driving motor as an example, such as a servo motor, and the driving motor is coaxially arranged with the rotating shaft 1022, that is, the motor rotating shaft of the driving motor is coaxially drivingly connected to the rotating shaft 1022. In the embodiment of the present application, a reducer is used as an intermediate member to connect the motor rotating shaft of the driving motor and the rotating shaft 1022, which not only occupies a small installation space but also has a high driving efficiency.

[0039] The second driving member 1031 in the above embodiment takes a cylinder as an example, and any cylinder that can drive the two clamping members to realize the clamping function of picking up and placing the workpiece is acceptable. In the embodiment of the present application, a thin pneumatic finger cylinder is specifically used. The thin pneumatic finger cylinder has a smaller volume and mass, which helps to optimize the rotation torque and installation space, and the smaller mass can reduce the inertia generated by rotation, thus helping to improve the driving positioning accuracy of the first driving member 1021.

[0040] Furthermore, in one embodiment, the second driving member 1031 can be arranged on one side of a radial direction of the rotating shaft 1022, and the two clamping members 1033 are arranged on the other side of the radial direction of the rotating shaft 1022. Compared with the superposition arrangement of the second driving member 1031 and the two clamping members 1033, the structure of the second driving member 1031 and the structure of the two clamping members 1033 in the embodiment of the present application are relatively independent respectively.

[0041] The superposition setting of the second driving member 1031 and the two clamping members 1033 can be understood as follows: There is a certain superposition in the structures of the second driving member 1031 and the two clamping members 1033, so that the rotational force arm is greater than the force arm of any single body among the second driving member 1031 and the two clamping members 1033. Since the structures of the second driving member 1031 and the two clamping members 1033 are relatively independent respectively, the rotational force arm can be understood as the larger single body force arm in the structures of the second driving member 1031 and the two clamping members 1033. Therefore, the positional relationship between the second driving member 1031 and the two clamping members 1033 in the embodiment of the present application can make the force arm of the rotating shaft 1022 smaller, thereby helping to reduce the torque.

[0042] In one embodiment, it can also be that the two clamping members 1033 and the second driving member 1031 are arranged on the same side of a radial direction of the rotating shaft 1022, and the two clamping members 1033 are movably arranged along the axial direction of the rotating shaft 1022 on the rotating shaft 1022, and the second driving member 1031 can drive the two clamping members 1033 to move relatively closer to or away from each other along the axial direction of the rotating shaft 1022.

[0043] Both the two clamping members 1033 and the second driving member 1031 can be directly connected to the rotating shaft 1022, and of course, an intermediate member can also be used for connection. At the same time, compared with the setting where the relative movement direction of the two clamping members 1033 is skewed to the axial direction of the rotating shaft 1022, the embodiment of the present application arranging the two clamping members 1033 along the axial direction of the rotating shaft 1022 can help make the rotational force arm of the rotating shaft 1022 uniform, and further help reduce the driving and positioning difficulty.

[0044] Furthermore, the clamping member 1033 in the above embodiment includes a jaw 10331 and a connecting portion 10332. The connecting portion 10332 is drivingly connected to the second driving member 1031. The connecting portion 10332 is slidably arranged along the axial direction of the rotating shaft 1022 on the rotating shaft 1022, and the jaw 10331 is elastically movably arranged along the second direction on the connecting portion 10332.

[0045] The two jaws 10331 corresponding to the two clamping members 1033 are used for picking and placing workpieces, and the connecting portion 10332 can be understood as an intermediate member connecting the jaw 10331 and the rotating shaft 1022. Specifically, the jaw 10331 and the connecting portion 10332 are elastically connected to avoid collision damage or damage to the workpiece during the process of the jaw 10331 picking and placing the workpiece. The specific direction of the elastic setting can be determined according to the direction of picking and / or placing the workpiece.

[0046] Among them, taking the elastic connection between the jaw 10331 and the connecting part 10332 by using an elastic member as an example, specifically taking the jaw 10331 and the connecting part 10332 being slidably connected and cooperated with a spring connection as an example, the elastic connection in the corresponding direction can be realized. Of course, the elastic member can also be any other elastic component that meets the requirements except the spring, such as a shrapnel, a tension spring, etc.

[0047] Furthermore, when the second driving member 1031 in the above embodiment drives the two clamping members 1033 to move relatively close to each other to the clamping state, the second driving member 1031 and the two clamping members 1033 are located in the region between the axial ends of the rotating shaft 1022.

[0048] It can be understood that when the two clamping members 1033 are in the state of clamping the workpiece, the second driving member 1031 and the two clamping members 1033 are structurally located within the structural length range of the rotating shaft 1022. In this way, it helps the rotating shaft 1022 to provide sufficient installation space for the second driving member 1031 and the two clamping members 1033, and at the same time, it also helps to provide a stable rotational driving effect for the second driving member 1031 and the two clamping members 1033.

[0049] Please refer to Figure 2 and Figure 3 Furthermore, the clamping assembly 103 in the above embodiment may further include two limiting members 1032. Each limiting member 1032 is arranged on a clamping member 1033, and the two limiting members 1032 are oppositely arranged along the axial direction of the rotating shaft 1022; each limiting member 1032 protrudes with a limiting block 10321 in the direction of approaching the other limiting member 1032 along the axial direction of the rotating shaft 1022, and a limiting groove 10322 is formed in the limiting block 10321.

[0050] When the loading mechanism 10 in the embodiment of the present application is used to carry a power battery with a top cover to be welded, the limiting groove 10322 provided on the limiting block 10321 of the limiting member 1032 can be in limiting cooperation with the edge of the top cover. Coupled with the fact that the two limiting members 1032 can move synchronously with the corresponding clamping members 1033 and thus also have a clamping effect, it plays a role in fixing the corresponding top cover, while the jaws 10331 of the clamping members 1033 are used to clamp and fix the body of the power battery. Of course, when used to carry other integrally structured workpieces, only the jaws 10331 can be provided.

[0051] Please refer to Figure 4 In addition, the embodiment of the present application further provides a processing device 20, including a transportation mechanism 201, a processing mechanism 202, and the loading mechanism 10 in any of the above embodiments. The transportation mechanism 201, the loading mechanism 10, and the processing mechanism 202 are sequentially arranged to be docked with the workpiece. The loading mechanism 10 is used to carry the workpiece transported by the transportation mechanism 201 to the processing mechanism 202.

[0052] Since the processing equipment 20 of the embodiment of the present application includes the feeding mechanism 10 in any of the above embodiments, it has the beneficial effects brought by the feeding mechanism 10 in any of the above embodiments, which will not be elaborated here.

[0053] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
