Description

Technical Field

[0001] The present invention relates to the technical field of battery preparation, and particularly to a mechanical claw for a separable and rotatable battery pack. Background Art

[0002] With the rapid development of technology, the degree of automation of today's product production lines is increasing day by day. In the production process of battery cells, multiple complex processes are required to achieve the processing and manufacturing of battery cells. In the entire production process, transferring the battery cells between various workstations of different processes is a key operation. Currently, this transfer work usually relies on the mechanical hand in the grasping device. The mechanical hand first grasps the battery cell from the workstation where the processing of the current process has been completed, and then transports it to other workstations to carry out the production of the next process.

[0003] To significantly improve production efficiency, enterprises often arrange multiple mechanical hands or use grasping devices equipped with multiple independent drives to perform the grasping work of battery cells. However, due to the different specifications of the loading and unloading devices on different production lines, the distance between the mechanical hands or other grasping components in the grasping device needs to be specifically designed and produced according to different production lines to ensure that it can adapt to various different production lines.

[0004] But the actual situation is that the distances between multiple conveyor belts of different specifications of loading and unloading devices are not exactly the same. This makes it necessary for enterprises to customize the grasping device for a specific production line alone, and the cost of mold customization is relatively high, which significantly increases the overall manufacturing cost of the equipment.

[0005] To solve this problem, mechanical devices that can simultaneously achieve the functions of distance separation and rotation during the process of grasping battery monomers have emerged on the market. However, most of the existing automatic distance-separating grasping devices achieve the distance-separating and rotating actions through screw, cylinder or connecting rod structures. Whether it is a screw, cylinder or connecting rod structure, a certain amount of time is required during operation, which undoubtedly reduces the efficiency of the device for performing the distance-separating operation on the battery monomer. In addition, in the process of using the above-mentioned structures, the control difficulty will increase due to the increase in the number of drive structures. The increase in control difficulty will, to a certain extent, affect the stability and efficiency during the distance separation and rotation of the battery monomer, and have an adverse impact on the smooth progress of production. Summary of the Invention

[0006] The purpose of the present invention is to provide a mechanical claw for a separable and rotatable battery pack to solve the problem in the existing battery automatic distance-separating grasping device that the use of more power structures has an adverse impact on its stability and efficiency during the distance separation and rotation of the battery.

[0007] To address the deficiencies of the above technical problems, the technical solution adopted by the present invention is a mechanical claw for a separable-distance rotating battery pack, which has a connecting frame for cooperating with a robotic arm. A distance-separating component is provided on the connecting frame, and a plurality of rotating cylinders are driven by the distance-separating component to adjust the distance between the plurality of rotating cylinders. A clamping cylinder is driven at the end of the rotating cylinder away from the connecting frame, and the clamping cylinder can clamp a battery cell.

[0008] The distance-separating component includes a distance-separating plate slidable on the connecting frame and a plurality of bearing plates for carrying the rotating cylinders.

[0009] A power cylinder is fixed on the distance-separating plate. The power cylinder can drive the distance-separating plate to slide vertically with the connecting frame as a support. A plurality of distance-separating grooves are evenly formed on the distance-separating plate, and the distance-separating grooves are inclined towards the center of the distance-separating plate.

[0010] The bearing plate slides horizontally, and rolling columns slidably engaged with the distance-separating grooves are provided on the bearing plate.

[0011] As a further optimization of the mechanical claw for a separable-distance rotating battery pack of the present invention: Three shock-absorbing members for stabilizing the displacement of the distance-separating plate are evenly provided on the connecting frame.

[0012] As a further optimization of the mechanical claw for a separable-distance rotating battery pack of the present invention: The shock-absorbing member includes a positioning frame fixed on the connecting frame, a damping rod and a stopper provided on the positioning frame. The damping rod and the stopper correspond to a reinforcing strip fixed on the distance-separating plate to reduce the vibration during the displacement of the distance-separating plate.

[0013] As a further optimization of the mechanical claw for a separable-distance rotating battery pack of the present invention: The power cylinder is fixed at the center of the distance-separating plate, and a stabilizing frame is fixed at the center of the connecting frame.

[0014] As a further optimization of the mechanical claw for a separable-distance rotating battery pack of the present invention: A plurality of weight-reducing grooves are formed on the distance-separating plate.

[0015] As a further optimization of the mechanical claw for a separable-distance rotating battery pack of the present invention: Elastic wheels are provided at the sliding engagement portion of the rolling column and the distance-separating groove.

[0016] As a further optimization of the mechanical claw for a separable-distance rotating battery pack of the present invention: The connecting frame includes a docking head for cooperating with the robotic arm and a support frame fixedly connected to the docking head. The side surface of the support frame away from the docking head is slidably engaged with the bearing plate.

[0017] As a further optimization of the mechanical claw for a separable-distance rotating battery pack of the present invention: The support frame is rectangularly arranged to allow a plurality of linearly distributed bearing plates to slide along the length direction of the support frame.

[0018] As a further optimization of the mechanical claw of the separable-distance rotating battery pack of the present invention: a slideway is provided on the support frame, and the slideway is in sliding fit with a slider provided on the bearing plate, and the cross-sections of the slideway and the slider are both dovetail-shaped.

[0019] As a further optimization of the mechanical claw of the separable-distance rotating battery pack of the present invention: the power cylinder is a telescopic cylinder.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the present invention, a stabilizing frame is fixedly connected to the support frame as a support to cooperate with the power cylinder to accurately drive the distance-dividing plate to achieve stable vertical displacement. During the vertical movement of the distance-dividing plate, multiple evenly distributed distance-dividing grooves on it play a key role. These distance-dividing grooves are in close fit with the rolling columns, and the movement of the distance-dividing plate directly drives the rolling columns to slide along the distance-dividing grooves. And the rolling columns are firmly connected to the bearing plate, so the bearing plate will also move synchronously. When multiple bearing plates move, they will slide smoothly along the support frame. In this way, the distance between multiple bearing plates can be flexibly adjusted. Since each bearing plate is equipped with a rotating cylinder and a clamping cylinder, the change in the distance between the bearing plates also means that the distance between the rotating cylinder and the clamping cylinder is adjusted. When the clamping cylinder clamps the battery monomer, precise control of the distance between multiple battery monomers can be achieved. A single power cylinder is used as the power source, and the distance-dividing operation is realized through a single distance-dividing plate. This simple and efficient design greatly reduces the vibration and deviation caused by the structural transmission error, and significantly improves the stability and efficiency during the distance division and rotation of the battery monomers.

[0022] Furthermore, in the present invention, the rotating cylinder and the clamping cylinder equipped on each bearing plate are used to realize the flexible rotation of the clamping cylinder, and then accurately adjust the rotation angle of the clamped battery monomer.

[0027] To better understand the present invention, the content of the present invention will be further clarified below in conjunction with embodiments, but the content of the present invention is not limited to the following embodiments.

[0028] As Figure 1 shown, a further optimization of a mechanical claw for a separable and rotatable battery pack. It has a connecting frame 1 for support, which is like a solid cornerstone of the entire mechanical claw, providing a stable foundation for the realization of its subsequent functions. Above the connecting frame 1, a spacing component 3 is cleverly arranged. The ingenuity of this component lies in its ability to be perfectly connected to a plurality of rotary cylinders 5 and can accurately separate the plurality of rotary cylinders 5 at equal distances. And each rotary cylinder 5 drives a clamping cylinder 6 for clamping the battery cell 2 respectively. These clamping cylinders 6 are like dexterous fingers and can accurately and powerfully hold the battery cell 2.

[0029] The connecting frame 1 has unique connectability and can be seamlessly docked with the robotic arm. Once the connection is completed, under the powerful and precise drive of the robotic arm, a plurality of clamping cylinders 6 can work together to firmly clamp a group of battery cells 2. Subsequently, this group of clamped battery cells 2 can be moved to the corresponding position to prepare for the subsequent processing procedures. It is worth mentioning that during the process of the robotic arm controlling the movement of this group of battery cells 2, the robotic arm demonstrates its excellent control ability. It can not only drive the movement of the battery cells 2 but also precisely control the operation of the spacing component 3 and the corresponding plurality of rotary cylinders 5. Through this precise control, a spacing and rotation operation can be performed on a group of battery cells 2, thus cleverly adapting to the specific requirements of the subsequent processing platform and providing great convenience and accuracy for the subsequent processing process.

[0030] As Figure 2As shown, the structure of the connecting frame 1 is very delicate. It mainly includes a docking head 101 for docking with the robotic arm and a support frame 102 that is firmly and fixedly connected to the docking head 101. Specifically, the support frame 102 is arranged in a regular rectangle. This shape design not only ensures the stability of the structure but also provides a good foundation for the subsequent installation of components. In the length direction of the support frame 102, a sliding structure is cleverly set. The sliding structure is a mutually cooperating slideway and slider. The slideway is provided on the support frame 102, and the slider is provided on the carrier plate 301. Moreover, the cross-sections of the slideway and the slider are both dovetail-shaped to ensure the stability of the sliding of the carrier plate 301 and at the same time maintain the connection stability between the support frame 102 and the carrier plate 301, enabling the multiple carrier plates 301 included in the distance separating assembly 3 to slide flexibly on the support frame 102. On one side of each carrier plate 301 facing away from the support frame 102, a rotary cylinder 5 is firmly fixed. These rotary cylinders 5 are like the power cores of the mechanical claws, providing strong power support for the movement of the clamping cylinder 6.

[0031] Rolling columns 302 are fixedly installed on one side of the carrier plate 301 along the width direction of the support frame 102. These rolling columns 302 are exquisitely designed, and one end that extends beyond the support frame 102 can flexibly slide in the distance separating groove 303. The distance separating groove 303 is cleverly opened on the distance separating plate 304. Specifically, the distance separating groove 303 is not simply arranged in a straight line but is arranged obliquely. One end of the distance separating groove 303 facing the docking head 101 is close to the center position of the distance separating plate 304, while the end facing away from the docking head 101 is far from the center position of the distance separating groove 303. This unique oblique setting lays the foundation for the subsequent distance separating operation. At the same time, in order to reduce the weight of the distance separating plate 304, a plurality of weight-reducing grooves are opened on the distance separating plate 304 to reduce the vibration caused by inertia during the movement of the distance separating plate 304, that is, to improve the stability and efficiency during the process of the distance separating plate 304 adjusting the distance between the multiple carrier plates 301.

[0032] On one side of the spacing plate 304, a power cylinder 305 is fixedly installed. This power cylinder 305 is a key component for realizing the spacing operation. The power cylinder 305 is firmly and fixedly connected to a stabilizing frame 306 fixedly arranged on the support frame 102. Among them, the power cylinder 305 is a telescopic cylinder. When the telescopic cylinder starts to move, a powerful force will push the spacing plate 304 to make an accurate displacement relative to the support frame 102. There is only one power cylinder 305, which is fixedly arranged at the center of the spacing plate 304. At the same time, the stabilizing frame 306 is also fixedly arranged at the center of the support frame 102, so that the power cylinder 305 can drive the spacing plate 304 to make a vertical displacement more balanced and stable. As the spacing plate 304 moves, a plurality of spacing grooves 303 formed thereon will drive a plurality of rolling columns 302 to perform corresponding actions, thereby changing the spacing between a plurality of bearing plates 301. Since the rotary cylinders 5 and the clamping cylinders 6 are fixed on the bearing plates 301, this operation also changes the spacing between a plurality of rotary cylinders 5 and a plurality of clamping cylinders 6, and finally realizes the purpose of changing the spacing between a group of a plurality of battery cells 2. At the same time, through the precise control of a plurality of rotary cylinders 5, the angle adjustment of a group of a plurality of battery cells 2 can also be realized, making the mechanical claw more flexible and changeable during the operation process, capable of meeting different processing requirements. At the same time, elastic wheels can be provided on the rolling columns 302 to reduce the hard friction between the rolling columns 302 and the spacing grooves 303, thereby further improving the stability of clamping the battery cells 2.

[0033] As Figure 3 shown, in order to further improve the stability and reliability of the mechanical claw during the working process, three shock-absorbing members 4 are evenly arranged on the support frame 102. The design of these shock-absorbing members 4 is extremely ingenious. Each shock-absorbing member 4 includes a positioning frame 403 fixedly arranged on the support frame 102. The positioning frame 403 is like the skeleton of the shock-absorbing member 4, providing a stable support for the installation of its subsequent components. On the positioning frame 403, a damping rod 401 and a stopper 402 are fixedly installed. These two components cooperate with each other to jointly play a shock-absorbing role. The telescopic end of the damping rod 401 and the detection end of the stopper 402 are accurately corresponded to a reinforcing strip 404 arranged on the spacing plate 304. When the power cylinder 305 starts and stops instantaneously, the spacing plate 304 will generate a certain vibration. At this time, the damping rod 401 and the stopper 402 will quickly play a role and effectively reduce the vibration amplitude of the spacing plate 304. During the process of spacing and flipping a group of battery cells 2, the stability of the entire mechanical claw can be greatly improved, ensuring the accuracy and reliability of the processing process, and providing a strong guarantee for producing high-quality products.

[0034] The specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various modifications or variations within the scope of the claims, which does not affect the essence of the present invention.
