Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery manufacturing, and more specifically, to a battery core taking and discharging device. Background Art

[0002] In modern production lines, automation equipment plays an important role, among which the one-time pick-and-place device is used to quickly and accurately manipulate materials in the production line, greatly improving efficiency. However, in fields with high precision requirements such as lithium batteries, traditional one-time pick-and-place devices have some significant problems.

[0003] Conventional one-time loading and placing devices generally use cylinders to control opening and closing. The dynamic response speed of the cylinder is slow and it is easy to cause inaccurate movement. This method has poor positioning accuracy and cannot meet the production line requirements for higher positioning accuracy. For example, in lithium battery production, incorrect positioning may lead to inaccurate assembly of battery cells, which will eventually affect the performance of the battery and even produce waste.

[0004] In addition, the traditional loading device generally has a limited number of pick-ups and put-aways at a time, and can usually only handle one or several workpieces at a time. Frequent loading and unloading operations are required in actual production. In large-scale production, frequent loading and unloading actions will lead to a decrease in overall production efficiency. Especially in countries such as my country where labor costs are rising year by year, if the production efficiency of equipment cannot be greatly improved, the production cost will continue to rise. Frequent operations increase the wear of equipment and reduce the service life of equipment. Furthermore, the existing loading equipment mostly uses cylinders as the power source, and its hardware equipment and electrical control system are complex in design, which not only increases the difficulty of equipment maintenance and replacement, but also reduces the stability and reliability of the equipment. In our daily life and industrial production, batteries are widely used and important. As a key component of batteries, battery cells play a decisive role in battery performance and life cycle. In the manufacturing process of battery cells, the use of automation devices has undoubtedly improved production efficiency and product quality. However, with the continuous improvement of market demand for battery quality and production efficiency, in the loading and unloading process of battery cells, traditional loading and unloading devices can no longer meet existing production needs.

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0023] Reference Figures 1 to 5 As shown, the utility model discloses a battery cell taking and placing device, specifically, the device comprises a mounting frame 10, a spacing adjustment mechanism 30 and a plurality of clamping claw mechanisms 20;

[0024] A plurality of the clamping mechanisms 20 are slidably mounted side by side on the mounting frame 10, and the spacing adjustment mechanism 30 is located on one side of the clamping mechanism 20, and the spacing between adjacent clamping mechanisms 20 is adjusted by the spacing adjustment mechanism 30;

[0025] The clamping mechanism 20 comprises a clamping jaw driving assembly 202, a fixed plate 201, a lifting rod 2025 and a scissors-type clamping jaw 203. The fixed plate 201 is slidably mounted on the mounting frame 10. The clamping jaw driving assembly 202 is arranged on the fixed plate 201. The lifting rod 2025 is driven by the clamping jaw driving assembly 202 to realize lifting movement on the fixed plate 201. One end of the scissors-type clamping jaw 203 is rotatably connected to one end of the lifting rod 2025. The lifting rod 2025 drives the scissors-type clamping jaw 203 to open and close.

[0026] Furthermore, a battery cell loading and unloading device also includes a first guide rail and a first guide slider, wherein the first guide rail 40 is installed on the inner sides of the opposite sides of the mounting frame 10, and multiple first guide sliders 401 are arranged on the first guide rail 40, and the first guide slider 401 makes a linear motion along the inner side of the mounting frame 10 on the first guide rail 40, and the two ends of multiple clamping mechanisms 20 are fixedly connected to the first guide slider 401, and the multiple spacing adjustment mechanisms are fixedly installed on the other two opposite sides of the mounting frame 10 where the first guide rail 40 is not arranged, and the movable end of the spacing adjustment mechanism is fixedly connected to one of the multiple clamping mechanisms 20, and the clamping mechanism 20 is driven by the spacing adjustment mechanism 30, and the freedom of the clamping mechanism 20 is controlled by the first guide rail 40 and the first guide slider 401 to realize the movement of the clamping mechanism 20. The spacing adjustment mechanism includes a first motor 301, a screw rod 302 and a screw rod nut 303. The output end of the first motor 301 is fixedly connected to the screw rod 302. The screw rod 302 is fixedly mounted on the mounting frame 10. The screw rod nut 303 is sleeved on the screw rod 302. The screw rod nut 303 is fixedly connected to the clamping mechanism 20. The screw rod nut 303 drives the clamping mechanism 20 to move along the first guide rail 40 through the drive of the first motor 301. The driving method using the motor is simple, easy to maintain, and can realize automatic control. Compared with manual or pneumatic, hydraulic and other driving methods, motor driving is more convenient and easy.

[0027] Further, such as Figures 1 to 5 As shown, both ends of the fixed plate 201 are fixedly connected to the first guide slider 401, and a plurality of gripper drive assemblies 202 are arranged above the fixed plate 201. Each two gripper drive assemblies 202 are connected by a transmission shaft and a plurality of lifting rods 2025 are arranged along the length direction of the fixed plate 201. The lifting rods 2025 pass through the fixed plate 201, one end of which is connected to the driving assembly, and the other end is connected to a plurality of scissor-type grippers 203. In this way, flexible control of the scissor-type grippers 203 can be achieved. Whether opening or closing the grippers, or performing grabbing operations at different heights, the lifting rods 2025 can be controlled by the driving assembly to achieve precise operation of the scissor-type grippers 203. A battery cell loading and unloading device also includes a vertical plate 50, a second guide rail 60 and a second guide slider 70; the vertical plate 50 is fixedly installed on the side of the fixed plate 201, the second guide slider 70 is arranged on the vertical plate 50, and the second guide slider 70 is arranged on the lifting plate 2034, which can realize the vertical lifting of the lifting plate 2034 and control the opening and closing of the scissor clamp 203.

[0028] Furthermore, the clamp driving assembly 202 includes a second motor 2021, a screw nut slider 2022, a swing connector 2023 and a lifting plate 2024; the output end of the second motor 2021 is connected to the screw nut slider 2022, and the screw nut slider block can be driven by the second motor to reciprocate in the horizontal direction, thereby ensuring the accuracy of the clamp driving assembly 202. One end of the swing connector 2023 is connected to the screw nut slider 2022, and the other end is connected to the lifting plate 2024, and the lifting plate 2024 is fixedly connected to the top of the lifting rod 2025. The swing connector 2023 plays a role in connecting and transmitting between the screw nut slider 2022 and the lifting plate 2024. When the screw nut slider 2022 performs a lateral translation movement along the screw, one end of the swing connector 2023 is driven to follow the movement. Because the other end of the swing connector 2023 is connected to the lifting plate 2024, and the connection is designed as a hinge connection, the lateral translation movement of the screw nut slider 2022 will be converted into the up and down movement of the lifting plate 2024 through the swing connector 2023. This arrangement can realize the rapid and stable lifting and lowering of the lifting rod 2025 under the drive of the second motor 2021. The lifting rod 2025 is also sleeved with a spring 90 on the outside, and the two ends of the spring 90 are respectively fixed to the bottom of the lifting plate 2024 and the bottom of the lifting rod 2025. The spring 90 is a compression spring, which can buffer the impact force of the lifting rod 2025 during the lifting process, reduce the equipment loss and vibration that may be caused by rapid lifting, and ensure the stable operation of the equipment. The spring 90 can also provide a clamping force to automatically return the lifting rod 2025 to the initialization position after stopping lifting, so as to facilitate the start of the next action and realize the automatic reset function. The battery cell loading and unloading device also includes a transmission shaft, and the two ends of the transmission shaft 2026 are respectively connected to a screw nut slider, and the two screw nut sliders are driven by the second motor to make reciprocating motion. This arrangement only requires one motor and one transmission shaft, and can drive two screw nut sliders at the same time, reducing the number of equipment and components, and reducing costs and operational complexity.

[0029] like Figure 2As shown, the scissor-type clamping jaw 203 comprises a first clamping jaw arm 2031, a second clamping jaw arm 2032, a clamping jaw base shaft 2033, a first connecting rod 2034 and a second connecting rod 2035. The design of the scissor-type clamping jaw 203 imitates the principle of scissors. This structure makes the clamping jaw simple and stable. The first clamping jaw arm 2031 and the second clamping jaw arm 2032 are hinged together in the middle part and provided with a through hole. The clamping jaw base shaft 2033 passes through the through hole so that the two clamping jaw arms can move relative to each other, which ensures that the two clamping jaw arms can move relative to each other from a structural point of view, and the movement is stable and reliable. In actual operation, the opening and closing of the clamping jaw arm can be well controlled by only controlling the position of the clamping jaw base shaft 2033. Therefore, the length of the clamping jaw base shaft 2033 is slightly larger than the width of the fixed plate 201, thereby achieving the purpose of flexibly controlling the grasping or releasing of the object, greatly improving the operation efficiency. One end of the first connecting rod 2034 and the second connecting rod 2035 are respectively at the top of the first clamping arm 2031 and the second clamping arm 2032, and the other end is connected to the bottom of the lifting rod 2025. The lifting plate 2024 drives the lifting rod 2025 to move up and down, driving the first connecting rod 2034 and the second connecting rod 2035, so that the scissor fork clamping jaw 203 can be opened and closed. By adjusting the movement of the lifting plate 2024 and the lifting rod 2025, the opening and closing angle and speed of the scissor fork clamping jaw 203 can be accurately controlled to meet the precise grasping requirements of different objects. The first clamping arm 2031 and the second clamping arm 2032 are provided with an anti-sliding block 110 on the inner side of the bottom end to enhance the clamping ability.

[0030] Furthermore, if Figure 3 to Figure 4 As shown, the battery core material taking and discharging device also includes a first clamping jaw mounting plate 80 and a second clamping jaw mounting plate 90, wherein the first clamping jaw mounting plate 80 and the second clamping jaw mounting plate 90 are fixedly connected to both sides of the fixed plate 201, and the two ends of the clamping jaw base shaft 2033 are respectively fixedly connected to the first clamping jaw mounting plate 80 and the second clamping jaw mounting plate 90. The clamping jaw base shaft 2033 is fixed in a precise position by the first clamping jaw mounting plate 80 and the second clamping jaw mounting plate 90, which is conducive to improving the working accuracy of the equipment and ensuring the accuracy and stability during the working process. Such a structural design can also effectively disperse the pressure borne by the clamping jaw base shaft 2033, thereby reducing the wear caused by long-term operation and extending the service life of the equipment. It is more convenient when the clamping jaw base shaft 2033 needs to be maintained or adjusted. For example, when the clamping jaw base shaft 2033 needs to be replaced, the first clamping jaw mounting plate 80 and the second clamping jaw mounting plate 90 can be disassembled separately for quick replacement.

[0031] The battery cell loading and unloading device further comprises an obtuse-angle connecting rod 100, the top end of the obtuse-angle connecting rod 100 is rotatably connected to the swing connecting member 2023, and the bottom end of the obtuse-angle connecting rod 100 is fixedly connected to the lifting plate 2024. The top and bottom ends of the obtuse-angle connecting rod 100 are respectively connected to the swing connecting member 2023 and the lifting plate 2024, forming a stable three-point support, thereby improving the stability of the structure.

[0032] In another embodiment, a plurality of spacing adjustment mechanisms 30 are provided on the mounting frame 10, and each spacing adjustment mechanism 30 controls a clamping mechanism 20, so that independent control and adjustment of different clamps can be achieved, thereby enhancing the operational flexibility of the equipment to adapt to different operational requirements.

[0033] The beneficial effects of the utility model are as follows: through the mounting frame, the spacing adjustment mechanism and a plurality of clamping mechanisms slidably mounted side by side on the mounting frame, high-efficiency, multi-piece parallel pick-and-place operations of the battery cells are achieved, and the spacing between adjacent clamping mechanisms can be adjusted to meet the needs of battery cells of different specifications, thereby improving the versatility and flexibility of the equipment.

[0034] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments.

These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
