Detailed implementation manners

[0035] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model will be described in detail below.

[0036] Refer to the following Figures 1-7 to describe the clamping assembly 10 for a power battery according to an embodiment of the present utility model, which includes: a bracket 100, a driving assembly 200, a jaw assembly 300, and a transmission assembly 400.

[0037] Specifically, the driving assembly 200 is disposed on the bracket 100, and an output end 201 is provided on the driving assembly 200; one end of the transmission assembly 400 is in driving connection with the output end 201, and the other end of the transmission assembly 400 is in driving connection with the jaw assembly 300. The transmission assembly 400 is used to drive the jaw assembly 300 to perform horizontal movement and rotation.

[0038] It can be understood that during the process of transporting the power battery in the production line, it is suitable to clamp the power battery through the clamping assembly 10, so that the power battery can be transported under the clamping of the clamping assembly 10 to complete the production and transportation of the power battery.

[0039] Specifically, the clamping assembly 10 includes: a bracket 100, a driving assembly 200, a jaw assembly 300, and a transmission assembly 400. The bracket 100 is suitable for providing a supporting function, so that other structures in the clamping assembly 10 can be constructed on the bracket 100 for subsequent use, including the driving assembly 200, the jaw assembly 300, and the transmission assembly 400. The driving assembly 200 is suitable for providing a driving force, so that the driving force can be subsequently transmitted to the jaw assembly 300 for use. During the transmission of the driving force, it is suitable to be transmitted through the transmission assembly 400 and transmitted to the jaw assembly 300 to drive the jaw assembly 300 to work, so as to realize the clamping or loosening of the battery by the jaw 314.

[0040] During the use of the transmission assembly 400, since the transmission assembly 400 is used to drive the jaw assembly 300 to perform horizontal movement and rotation, so that the jaw assembly 300 can drive the battery to perform horizontal movement and rotation according to requirements, so that the clamping assembly 10 has more functions during use, not only can the battery be transported more reliably, but also the integration degree of the clamping assembly 10 can be improved, and the production and construction cost can be reduced.

[0041] For the clamping assembly 10 for a power battery according to an embodiment of the present utility model, the driving force provided by the driving assembly 200 is transmitted to the jaw assembly 300 through the use of the transmission assembly 400 to drive the jaw assembly 300 to be used. Since the transmission assembly 400 is configured to drive the jaw assembly 300 to perform horizontal movement and rotation, so that the clamping assembly 10 can drive the battery to perform horizontal movement and rotation when clamping the power battery, realizing an integrated design. At the same time, while improving the transportation efficiency of the battery, the structure of the clamping assembly 10 can be made more compact, and while reducing the production cost, a miniaturized design can be realized.

[0042] In some embodiments, a guiding groove 110 is provided on the bracket 100; the transmission assembly 400 includes: a first transmission member 410 and a second transmission member 420. One end of the first transmission member 410 is connected to the jaw assembly 300; one end of the second transmission member 420 is in transmission connection with the output end 201, and the other end of the second transmission member 420 is in transmission connection with the other end of the first transmission member 410. The second transmission member 420 is used to drive the first transmission member 410 to move within the guiding groove 110. It can be understood that the transmission assembly 400 includes the first transmission member 410 and the second transmission member 420. The driving member 220 is adapted to be connected to the second transmission member 420, and then the second transmission member 420 drives the first transmission member 410 to move, so that the first transmission member 410 can drive the jaw assembly 300 to move for use, so as to constitute the use effect of the clamping assembly 10. And because the guiding groove 110 is provided on the bracket 100, the guiding groove 110 is adapted to be disposed opposite to the first transmission member 410, so that the first transmission member 410 can move under the limitation of the guiding groove 110 to drive the jaw assembly 300 to move, thereby constituting the horizontal movement and rotation of the jaw assembly 300.

[0043] In some embodiments, a plurality of first transmission members 410 are arranged at intervals and include: a base 411, a transmission mounting seat 412, a rotating shaft 413, a rotating plate 414 and a follower 415. The base 411 is connected to the jaw assembly 300; the transmission mounting seat 412 is disposed on the base 411; the rotating shaft 413 is rotatably connected to the transmission mounting seat 412, and the rotating shaft 413 passes through the guiding groove 110; the rotating plate 414 is rotatably connected to the rotating shaft 413; the follower 415 is rotatably disposed on the rotating plate 414, and the follower 415 is in transmission connection with the second transmission member 420. The follower 415 drives the rotating shaft 413 to move within the guiding groove 110 through the rotating plate 414. That is to say, during the use of the first transmission member 410, the first transmission member 410 is adapted to be disposed opposite to the jaw assembly 300 one by one, so that the first transmission member 410 can drive the jaw assembly 300 to work more precisely and reliably. Specifically, the first transmission member 410 is adapted to include: a base 411, a transmission mounting seat 412, a rotating shaft 413, a rotating plate 414 and a follower 415. The base 411 is adapted to provide a supporting function, so that the transmission mounting seat 412 can be assembled on the base 411, and the driving force provided by the driving assembly 200 is adapted to be transmitted to the first transmission member 410 through the second transmission member 420, and sequentially through the follower 415, the rotating plate 414, the rotating shaft 413, the transmission mounting seat 412, the base 411, and finally transmitted to the jaw assembly 300 to drive the jaw assembly 300 to perform horizontal movement and rotation.

[0044] Specifically, the driving force is suitable for being transmitted through the second transmission member 420 and driving the first transmission member 410 to move. Since the first transmission member 410 is suitable for including a follower 415, the follower 415 is suitable for moving in the guide groove 110, so as to convert the driving force into movement and rotation to act on the clamping jaw assembly 300 under the restriction of the guide groove 110, so as to realize horizontal movement and rotation of the clamping jaw assembly 300.

[0045] In some embodiments, there are multiple guide grooves 110, and each guide groove 110 includes: a first guide portion 111 and a second guide portion 112. The first guide portion 111 extends in a horizontal direction. When the follower 415 moves in the first guide portion 111, it drives the clamping jaw assembly 300 to move horizontally; the second guide portion 112 is connected to one end of the first guide portion 111 away from the driving assembly 200. When the follower 415 moves in the second guide portion 112, it drives the clamping jaw assembly 300 to rotate.

[0046] It is understood that since the clamping assembly 10 is suitable for simultaneously clamping multiple batteries, a corresponding number of jaw assemblies 300 can be provided corresponding to the number of batteries to achieve precise control of transportation. In order to ensure precise control of each jaw assembly 300, it is appropriate to provide multiple guide slots 110, each corresponding to each jaw assembly 300.

[0047] Specifically, each guide slot 110 includes a first guide portion 111 and a second guide portion 112. When the second transmission member 420 drives the follower 415 to move within the first guide portion 111, the follower 415 is adapted to move horizontally, thereby driving the horizontal movement of the clamping jaw assembly 300. Furthermore, when the second transmission member 420 drives the follower 415 to move within the second guide portion 112, the follower 415 rotates within the second guide portion 112, thereby driving the clamping jaw assembly 300 to rotate.

[0048] In some embodiments, at least two guide grooves 110 are symmetrically arranged relative to the center of the bracket 100, and the extension direction of the second guide portion 112 provided on one side of the center of the bracket 100 is opposite to the extension direction of the second guide portion 112 provided on the other side of the center of the bracket 100; and / or the length dimensions of the multiple first guide portions 111 are first lowered and then raised along the extension direction of the bracket 100.

[0049] In this way, since the extension directions of the second guide portions 112 on both sides are opposite, the rotation directions of the clamping jaw assemblies 300 on both sides are the same, thereby avoiding interference during use of the clamping assembly 10 and making the use of the clamping assembly 10 more reliable.

[0050] Moreover, since the second transmission member 420 is used to transmit the driving force, when the driving jaw assembly 300 is horizontally moved, the farther the jaw assembly 300 is from the driving member 220, the greater the horizontal distance that the jaw assembly 300 needs to move. Therefore, the length dimensions of the plurality of first guiding portions 111 first decrease and then increase along the extending direction of the bracket 100, so as to make the use of the clamping assembly 10 more reliable.

[0051] In some embodiments, multiple groups of the second transmission members 420 are relatively arranged at the output end 201, and each group of the second transmission members 420 includes: a first transmission rod 421, a second transmission rod 422, a first connecting shaft 423, and a plurality of second connecting shafts 424. One end of the first transmission rod 421 is in transmission connection with the output end 201; one end of the second transmission rod 422 is in transmission connection with the other end of the first transmission rod 421; the first connecting shaft 423 is rotatably connected to the connection portion of the first transmission rod 421 and the second transmission rod 422; the second connecting shaft 424 is connected to the first transmission member 410. At least one second connecting shaft 424 is arranged at the free end of the second transmission rod 422, and at least another second connecting shaft 424 is arranged in the middle of the first transmission rod 421, and the plurality of second connecting shafts 424 are in the same horizontal direction.

[0052] It can be understood that multiple groups of the second transmission members 420 can be relatively arranged at the output end 201, and one end of each second transmission member 420 is connected to the output end 201, so that the driving assembly 200 can synchronously control the use of the multiple second transmission members 420, enabling the clamping assembly 10 to synchronously transport the battery during use. At the same time, the miniaturized design of the clamping assembly 10 can be realized, making the arrangement of the clamping assembly 10 more compact and reliable.

[0053] Specifically, the second transmission member 420 is adapted to include a first transmission rod 421 and a second transmission rod 422, and the driving force is adapted to be transmitted to the second transmission rod 422 and then transmitted to the first transmission rod 421 through the second transmission rod 422. A first connecting shaft 423 is adapted to be arranged at the connection portion of the first transmission rod 421 and the second transmission rod 422, and the first connecting shaft 423 is adapted to be rotatably connected to realize the structural change of the first transmission rod 421 and the second transmission rod 422, and at the same time drive the first transmission member 410 to move according to requirements to realize the use of the clamping assembly 10.

[0054] At the same time, a second connecting shaft 424 can be arranged in the middle of the first transmission rod 421, and the second connecting shaft 424 is adapted to be connected to the follower 415 to drive the follower 415 to move to form the subsequent use of the jaw assembly 300. Similarly, the second connecting shaft 424 can also be constructed at the free end of the second transmission rod 422, which can also drive the follower 415, enabling the clamping assembly 10 to have a high working efficiency during use.

[0055] In some embodiments, the jaw assembly 300 includes: a jaw mounting base 310, a slider 311, a jaw cylinder 313, and jaws 314. The jaw mounting base 310 is connected to the transmission assembly 400; the slider 311 is slidably connected to the jaw mounting base 310. The moving direction of the slider 311 is perpendicular to the horizontal direction, and jaw mounting portions 312 are respectively provided at both ends of the slider 311; the jaw cylinder 313 is connected to the slider 311; the jaws 314 are provided on the jaw mounting portions 312, and the jaw cylinder 313 is in transmission connection with the jaws 314. It can be understood that the jaw mounting base 310 is adapted to provide a mounting position. The slider 311 is connected to the jaw mounting base 310 and is adapted to slide to adjust the working position of the jaws 314, so that the jaw assembly 300 can adjust the output performance according to the usage requirements of the clamped battery, making the clamping effect of the jaw assembly 300 on the battery more reliable, and enabling the jaw assembly 300 to have higher applicability during use. At the same time, a jaw cylinder 313 is also provided to provide driving force to drive the jaws 314 to move, so that the jaw assembly 300 can clamp and release the battery, making the performance of the jaw assembly 300 higher.

[0056] In some embodiments, multiple jaws 314 are arranged in parallel, and the working directions of the relatively arranged jaws 314 are opposite to each other. It can be understood that arranging multiple jaws 314 in parallel and having the working directions of the relatively arranged jaws 314 opposite to each other enables the jaws 314 to clamp the battery from both sides of the battery, making the clamping of the battery by the jaw assembly 300 more reliable.

[0057] In some embodiments, the jaw 314 further includes: a sensor 316, and the sensor 316 is provided at the free end of the jaw 314. In this way, by providing the sensor 316 at the free end of the jaw 314, the sensor 316 is adapted to detect the battery, provide feedback on the use of the jaw assembly 300, and adjust the performance of the clamping assembly 10 according to the feedback, making the use of the clamping assembly 10 more reliable.

[0058] In some embodiments, a jaw guiding portion is provided on the jaw mounting base 310, and a bracket guiding portion is provided on the bracket 100. The jaw guiding portion and the bracket guiding portion are in guiding cooperation. In this way, by enabling the jaw guiding portion and the bracket guiding portion to be in guiding cooperation, when the jaw assembly 300 moves, it is adapted to move along the extending direction of the bracket 100, making the use of the clamping assembly 10 more reliable.

[0059] In some embodiments, the driving assembly 200 further includes: a driving mount 210, a floating joint 230, a driving buckle 240, and a driving pull shaft 250. The driving mount 210 is disposed on the bracket 100, and a driving member 220 is provided on the driving mount 210. An output end 201 is provided at an end of the driving member 220; the floating joint 230 is disposed on the output end 201; one end of the driving buckle 240 is connected to the floating joint 230; one end of the driving pull shaft 250 is connected to the other end of the driving buckle 240, and the other end of the driving pull shaft 250 is rotatably connected to the transmission assembly 400. In this way, the driving mount 210 is adapted to provide a supporting function, so that the driving member 220 can be more reliably mounted on the driving mount 210 for use. And an output end 201 is provided at an end of the driving member 220, so that the driving member 220 is adapted to provide a driving function to the output end 201 to realize the use of the clamping assembly 10. At the same time, the floating joint 230 is used at the output end 201, so that the floating joint 230 can better transmit power and avoid affecting the driving member 220 during the transmission process, so that the driving assembly 200 is more reliable in use. And the driving buckle 240 and the driving pull shaft 250 are used for connection, so that the transmission of the driving force is more reliable, thereby improving the use performance of the clamping device.

[0060] In some embodiments, the driving member 220 is a driving cylinder. It can be understood that the driving member 220 is a driving cylinder, so that the driving member 220 can provide a more reliable driving force to drive the jaw assembly 300 for use as required.

[0061] The transport device according to an embodiment of the present invention includes: the clamping assembly 10 as described above.

[0062] In some specific embodiments, when grasping the battery cell, the rotating variable pitch battery cell gripper 314 mechanism, driven by the robot, moves from the original position to the material taking waiting position on the restraint tray of the deconstraint machine in the material taking state, and then the robot slowly moves to the material taking position. The parallel gripper cylinder 313 operates to clamp, driving the gripper 314 to clamp the battery cell in place. Then the robot drives the mechanism to the material placing waiting position, the pen-shaped cylinder retracts, and the buckle drives the near-cylinder ends of the left and right connecting rods to move towards the cylinder installation side, and the far-cylinder ends of the connecting rods drive the connecting rods to move away from the cylinder installation side. The middle part and the far end part of the connecting rod drive the driving plate to expand towards both sides through the fixed shaft, and the connecting plate connected to the driving plate drives the fixture mounting plate, and the gripper 314 mounting plate drives the battery cell gripper 314 to expand towards both sides. During the expansion process, the cam follower 415 moves along the rotating guide plate. When turning 90 degrees, the cam follower 415 turns around the movement track, driving the rotating shaft 413 to rotate 90 degrees clockwise around the Z-axis. The entire battery cell gripper 314 rotates 90 degrees as a whole driven by the rotating shaft 413. After the pen-shaped cylinder reaches the position, the entire rotating variable pitch gripper 314 mechanism is in the material placing state. The robot moves to the material placing position, the parallel gripper cylinder 313 releases, and the battery cell is placed on the production line. Then the robot drives the mechanism back to the original position;

[0063] After reaching the original position, the pen-shaped cylinder extends, and the buckle drives the near-cylinder ends of the left and right connecting rods to move away from the cylinder installation side, and the far-cylinder ends of the connecting rods drive the connecting rods to move towards the cylinder installation side. The middle part and the far end part of the connecting rod drive the driving plate to contract towards the middle through the fixed shaft, and the connecting plate connected to the driving plate drives the fixture mounting plate, and the gripper 314 mounting plate drives the battery cell gripper 314 to contract towards the middle. During the contraction process, the cam follower 415 moves along the rotating guide plate. When turning 90 degrees, the cam follower 415 turns around the track, driving the rotating shaft 413 to rotate 90 degrees counterclockwise around the Z-axis. The entire battery cell gripper 314 rotates 90 degrees as a whole driven by the rotating shaft 413. After the pen-shaped cylinder reaches the position, the entire rotating variable pitch gripper 314 mechanism is in the material taking state; thus, the rotating variable pitch gripper 314 mechanism completes one material taking and placing action.

[0064] In this way, since the clamping assembly 10 as shown above is provided in the transportation device, the driving force provided by the driving assembly 200 is transmitted to the gripper assembly through the transmission assembly 400 to drive the gripper assembly for use. Since the transmission assembly 400 is configured to drive the gripper assembly 300 to move horizontally and rotate, so that the clamping assembly 10 can drive the battery to move horizontally and rotate when clamping the power battery, while improving the transportation efficiency of the battery, the structure of the clamping assembly 10 can be made more compact, and miniaturized design can be achieved while reducing the production cost.

[0065] Other configurations and operations of the transportation device according to the embodiments of the present utility model are known to those of ordinary skill in the art and will not be described in detail here.
