Description

Technical Field

[0001] The present invention relates to the technical field of battery processing, and in particular to a battery cell transporting device and a transporting method. Background Art

[0002] Lithium batteries are widely used in new energy vehicles and energy storage industries. With people's attention and investment in new energy, new energy vehicles have developed rapidly, thereby driving the rapid improvement of lithium battery technology and increasing the market demand for square shell batteries among new batteries.

[0003] During the battery assembly process, battery cells need to be transported to different workstations for processing. During this process, materials need to be loaded and unloaded continuously. In the traditional battery cell transportation process, a robot is generally used to clamp the battery cells and transfer the battery cells to various workstations. Traditional robots transport battery cells by clamping. During the transportation process, the battery cells are prone to falling, resulting in a major safety hazard during the transportation process.

[0004] In order to solve the problem of battery cells easily falling during transportation, some handling manipulators that can improve the handling stability have also come into being. For example, the patent application with the Chinese patent publication number CN117945144A discloses a handling gripper for battery cell transportation. By setting a locking mechanism, it is convenient to maintain the height of the negative pressure tube when the battery cell falls, so that the clamping claws on both sides can be kept in a clamped state, and the battery cell can be prevented from slipping in the event of a fall. Although this application can improve the stability of battery cell transportation to a certain extent, in this application, the battery cell always has a tendency to move downward. Therefore, during the transportation process, the risk of falling is still not small, and there is still a large safety hazard.

DETAILED DESCRIPTION

[0045] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0046] like Figures 1 to 9 As shown, the present invention provides a battery cell transport device, which is mainly used to transport battery cell workpieces in square shell batteries.

[0047] For the convenience of explanation, in this embodiment, each direction is as follows Figure 1 As shown, the first direction is the front-to-back direction.

[0048] like Figure 1 and Figure 2 As shown, the battery cell transporting device provided by the present invention includes a mounting seat 1, a steering mechanism 2 and a clamping mechanism 3, the steering mechanism 2 is arranged on the mounting seat 1, the clamping mechanism 3 includes a clamping support seat 31, a first clamping component 32 and a second clamping component 33, the first clamping component 32 and the second clamping component 33 are both arranged on the clamping support seat 31, the first clamping component 32 clamps the battery cell workpiece 5 along a first direction, and the second clamping component 33 clamps the battery cell workpiece 5 along a second direction, the second direction is orthogonal to the first direction, and the clamping support seat 31 is connected to the steering mechanism 2.

[0049] Specifically, before transporting the battery cell workpiece 5, the first clamping assembly 32 and the second clamping assembly 33 appear to be in a vertical state as a whole, and a transport space for clamping the battery cell workpiece 5 is formed between the first clamping assembly 32 and the second clamping assembly 33, and the transport space is in a downward-opening state. When transporting the battery cell workpiece 5, the external conveying device conveys the battery cell workpiece 5 to the bottom of the battery cell conveying device, for example, a conveyor belt is used to convey the battery cell workpiece 5 to the bottom of the battery cell conveying device, and the external manipulator is connected to the mounting seat 1 to drive the entire battery cell conveying device to move downward. At this time, the battery cell workpiece 5 enters the transport space, and the first clamping assembly 32 and the second clamping assembly 33 jointly clamp the battery cell workpiece 5. The first clamping assembly 32 clamps the battery cell workpiece 5 in the front-to-back direction, and the second clamping assembly 33 clamps the battery cell workpiece 5 in the left-to-right direction. At this time, the battery cell workpiece 5 is in a vertical state.

[0050] Furthermore, after the first clamping assembly 32 and the second clamping assembly 33 clamp the battery workpiece 5 together, the steering mechanism 2 drives the clamping support seat 31 to rotate, and the rotation of the clamping support seat 31 drives the first clamping assembly 32 and the second clamping assembly 33 to rotate, thereby driving the battery workpiece 5 to rotate. More specifically, when viewed from the front, the clamping support seat 31 drives the first clamping assembly 32 and the second clamping assembly 33 to rotate clockwise, so that the battery workpiece 5 is turned from a vertical state to a horizontal state. When viewed from the front, the first clamping assembly 32 clamps the battery workpiece 5 in the front-to-back direction, and the second clamping assembly 33 rotates clockwise. The component 33 clamps the battery cell workpiece 5 in the vertical direction. Compared with the existing transporting device, the battery cell workpiece 5 is always in a vertical state and is easy to fall during transport. During transport, the battery cell transporting device of this embodiment transports the battery cell workpiece 5 in a horizontal state. The battery cell workpiece 5 is clamped in the horizontal direction by the first clamping component 32, and the battery cell workpiece 5 is clamped in the vertical direction by the second clamping component 33, thereby avoiding the risk of the battery cell workpiece 5 falling vertically due to gravity, and the clamping stability is better, which effectively improves the stability of battery cell transport and reduces the safety hazards during battery cell transport.

[0051] In some embodiments, there are multiple clamping mechanisms 3 , and the multiple clamping mechanisms 3 are arranged on the mounting base 1 at intervals along the left-right direction, so that multiple battery workpieces 5 can be transported at the same time, which improves the transportation efficiency.

[0052] In this embodiment, the number of the clamping mechanisms 3 is four. In some other embodiments, the number of the clamping mechanisms 3 can be adjusted according to actual conditions.

[0053] In some embodiments, the battery cell transporting device further includes a control unit, which is electrically connected to the steering mechanism 2 and the clamping mechanism 3 respectively, resulting in a higher degree of automation.

[0054] In some embodiments, the control unit is a PLC (Programmable Logic Controller).

[0055] In some other embodiments, the control unit may also be a control device such as an industrial computer.

[0056] In some embodiments, as Figures 3 to 5 As shown, the first clamping assembly 32 includes a first clamping cylinder 321 and two first clamping jaws 322. The fixed end of the first clamping cylinder 321 is arranged on the clamping support seat 31, and the movable ends of the first clamping cylinder 321 are respectively connected to the two first clamping jaws 322 to drive the two first clamping jaws 322 to approach or move away from each other along the first direction. Specifically, the first clamping cylinder 321 is a finger cylinder, which can drive the two first clamping jaws 322 to approach or move away from each other along the front and back directions. It has a fast response speed and can clamp the battery workpiece 5 more stably, thereby improving the stability of transportation.

[0057] In some embodiments, as Figures 3 to 5 As shown, the first clamping assembly 32 also includes a first clamping connecting plate 323, the first clamping claw 322 is connected to the first clamping connecting plate 323, the clamping mechanism 3 also includes a third clamping assembly 34, the third clamping assembly 34 includes a third clamping cylinder 341 and a third clamping claw 342, the fixed end of the third clamping cylinder 341 is provided on the first clamping connecting plate 323, the movable end of the third clamping cylinder 341 is connected to the third clamping claw 342 to drive the third clamping claw 342 to move along the second direction. Specifically, before carrying the battery workpiece 5, the third clamping claw 342 and the first clamping claw 322 are both in a vertical state, the steering mechanism 2 turns forward, and from the front, the two The first clamping jaw 322 clamps the battery workpiece 5 in the front-to-back direction, and the second clamping assembly 33 clamps the battery workpiece 5 in the left-to-right direction. At this time, the third clamping cylinder 341 drives the third clamping jaw 342 to move to the right, and the third clamping jaw 342 and the second clamping assembly 33 cooperate to clamp the battery workpiece 5. Before turning, the battery workpiece 5 is in a vertical state. By setting the third clamping assembly 34 to cooperate with the second clamping assembly 33 to clamp the battery workpiece 5, the clamping effect is better and the clamping is more stable, which effectively prevents the battery workpiece 5 from falling, and can better prevent the battery workpiece 5 from being thrown out during the turning process, thereby improving the stability of the battery workpiece 5 during transportation.

[0058] In some embodiments, the number of the third clamping components 34 is two, which provides better clamping stability.

[0059] In some embodiments, as Figures 3 to 5 As shown, the third clamping assembly 34 also includes a third buffer block 343, which is arranged at the end of the third clamping jaw 342. The third buffer block 343 is made of plastic material and has a certain anti-slip effect. At the moment when the third clamping jaw 342 clamps the battery workpiece 5, the third buffer block 343 can also play a buffering role to prevent damage to the battery workpiece 5.

[0060] In some embodiments, as Figures 3 to 5 As shown, the third clamping assembly 34 also includes a third guide rail 344, which is provided on the first clamping connecting plate 323, and the third clamping jaw 342 is slidably connected to the third guide rail 344. By providing the third guide rail 344, the movement of the third clamping jaw 342 can be made more stable.

[0061] In some embodiments, as Figures 3 to 5As shown, the first clamping assembly 32 also includes a first supporting plate 324, one end of the first supporting plate 324 is connected to the first clamping jaw 322, and the other end of the first supporting plate 324 extends along the first direction. Specifically, the first supporting plate 324 is located at the end of the first clamping jaw 322. There are two first supporting plates 324, and each first clamping jaw 322 is connected to a first supporting plate 324. The first supporting plate 324 located on the front side extends backward, and the first supporting plate 324 located on the rear side extends forward. After the battery workpiece 5 is turned to a horizontal state, the first supporting plate 324 is located below the battery workpiece 5. The first supporting plate 324 can better support the battery workpiece 5 and prevent the battery workpiece 5 from falling, thereby further improving the stability of the battery workpiece 5 during transportation.

[0062] In some embodiments, as Figures 3 to 5 As shown, the first clamping assembly 32 also includes a first detection unit 325, which is arranged at the end of the first clamping jaw 322 and is located on the side away from the handling space. The first detection unit 325 is used to detect whether the first clamping jaw 322 clamps the battery workpiece 5. Before the battery workpiece 5 is turned, if the first detection unit 325 does not detect the battery workpiece 5, it means that the battery workpiece 5 has not entered the handling space. At this time, the control unit will not control the steering mechanism 2 to turn. After the battery workpiece 5 is turned and becomes horizontal, the manipulators at other stations will clamp the battery workpiece 5. If the first detection unit 325 detects that the battery workpiece 5 is still clamped by the first clamping jaw 322, the control unit will not control the steering mechanism 2 to turn. Only after the battery workpiece 5 is clamped by the manipulators at other stations will the steering mechanism 2 turn. By setting the first detection unit 325, the degree of automation can be improved, the safety of the battery workpiece 5 during transportation can be improved, and safety risks can be avoided.

[0063] In some embodiments, the first detection unit 325 is a photoelectric switch, which has a better detection effect.

[0064] In some embodiments, as Figures 3 to 5As shown, the first clamping assembly 32 also includes a first limiting column 326, a first limiting nut 327 and two first limiting blocks 328, one of the first limiting blocks 328 is provided on one of the first clamping connecting plates 323, and the other first limiting block 328 is provided on the other first clamping connecting plate 323. The first limiting column 326 is a stud, and the first limiting column 326 is threadedly connected to one of the first limiting blocks 328. Specifically, the front end of the first limiting column 326 is threadedly connected to the first limiting block 328 on the front side, and the rear end of the first limiting column 326 can abut against the first limiting block 328 on the rear side. By setting the first limiting column 32 6. The distance between the two first clamping connecting plates 323 can be limited, that is, the distance between the two first clamping jaws 322 can be limited. When clamping battery workpieces 5 of different specifications, the position of the first limiting column 326 can be adjusted, and then the position of the first limiting column 326 can be fixed with the first limiting nut 327. It can be understood that slight errors may occur during the movement of the first clamping cylinder 321. By setting the first limiting column 326, this error can be avoided from causing the two first clamping jaws 322 to move excessively and clamp the battery workpiece 5, thereby reducing the risk of damage to the battery workpiece 5 and improving the stability and safety of the battery workpiece 5 during transportation.

[0065] In some embodiments, as Figures 3 to 5 As shown, the first clamping assembly 32 also includes a first guide rail 329, which is arranged on the clamping support seat 31, and the first clamping connecting plate 323 is slidably connected to the first guide rail 329. By setting the first guide rail 329, the movement of the first clamping connecting plate 323 can be made more stable.

[0066] In some embodiments, as Figures 6 to 8As shown, the second clamping assembly 33 includes a second clamping seat 331, a second clamping cylinder 332, a second connecting rod 333 and a second clamping claw 334. The second clamping seat 331 is arranged on the clamping support seat 31, and the second clamping claw 334 is rotatably connected to the second clamping seat 331. The fixed end of the second clamping cylinder 332 is arranged on the second clamping seat 331, and the movable end of the second clamping cylinder 332 is connected to one end of the second connecting rod 333, and the other end of the second connecting rod 333 is connected to the second clamping claw 334. Specifically, the second clamping claw 334 includes a second connecting portion 3341 and a second sandwiching portion 3342. The second clamping claw 334 is an L-shaped structure as a whole. Before the second clamping assembly 33 clamps the battery core workpiece 5, the second clamping seat 331 is in a vertical state, the second connecting portion 3341 of the second clamping claw 334 is in a vertical state, and the second clamping claw 334 is in a vertical state. The second clamping part 3342 of the second clamping jaw 334 is in a horizontal state. After the battery workpiece 5 enters the transportation space, viewed from the front, the second clamping cylinder 332 works and drives the second clamping jaw 334 to rotate clockwise through the second connecting rod 333, and the second connecting part 3341 becomes horizontal, and the second clamping part 3342 becomes vertical. The second clamping part 3342 and the second clamping seat 331 jointly clamp the battery workpiece 5. It can be understood that there is a gap between the two electrodes of the battery workpiece 5. Through such a design, that is, the second clamping jaw 334 is designed as an L-shaped structure, the battery workpiece 5 can be better clamped around this gap, the clamping range can be expanded as much as possible, and the center part of the battery workpiece 5 can be better clamped, thereby improving the stability of the clamping and thus improving the stability of the battery workpiece 5 during transportation.

[0067] In some embodiments, as Figures 6 to 8 As shown, the second clamping assembly 33 also includes a second connecting seat 335 and a second displacement cylinder 336. The second connecting seat 335 is arranged on the clamping support seat 31, and the fixed end of the second displacement cylinder 336 is arranged on the second connecting seat 335. The movable end of the second displacement cylinder 336 is connected to the second clamping seat 331 to drive the second clamping seat 331 to move along the second direction. Specifically, before clamping the battery cell workpiece 5, the second displacement cylinder 336 can be set to drive the second clamping seat 331 to move left and right, so that the position of the second clamping seat 331 can be adjusted to adapt to battery cell workpieces 5 of different specifications, with better adaptability.

[0068] In some embodiments, as Figures 6 to 8As shown, the second clamping assembly 33 further includes a second follower block 337, the second clamping seat 331 includes a second connecting portion 3311 and a second clamping portion 3312, the second connecting portion 3311 is connected to the movable end of the second displacement cylinder 336, the second follower block 337 is slidably connected to the second clamping portion 3312, one end of the second follower block 337 is connected to the movable end of the second clamping cylinder 332, and the other end of the second follower block 337 is connected to the second connecting rod 333. Specifically, The second clamping assembly 33 also includes a second guide rail, which is arranged on the second clamping part 3312, and the second follower block 337 is slidably connected to the second guide rail. The second connecting part 3341 in the second clamping jaw 334 is rotatably connected to the second clamping seat 331 through a rotating shaft, and the movable end of the second clamping cylinder 332 is connected to the second follower block 337 to drive the second follower block 337 to slide and drive the second clamping jaw 334 to rotate around the rotating shaft, so that the rotation of the second clamping jaw 334 is more stable and smooth.

[0069] In some embodiments, as Figures 6 to 8 As shown, the second clamping assembly 33 further includes two second limiting blocks 338 and two second limiting columns 339. The two second limiting blocks 338 are spaced apart and arranged on the second clamping seat 331. The second follower block 337 is provided with a follower limiting portion 3371. One end of one of the second limiting columns 339 is threadedly connected to one of the second limiting blocks 338, and the other end of the second limiting column 339 can abut against the follower limiting portion 3371. One end of the other second limiting column 339 is threadedly connected to the follower limiting portion 3371. The other end of the second limiting column 339 can abut against another second limiting block 338. It can be understood that by setting two second limiting blocks 338 and two second limiting columns 339, the movement amplitude of the second follower block 337 can be limited, thereby limiting the rotation amplitude of the second clamping jaw 334. By adjusting the position of the two second limiting columns 339, the movement amplitude of the second follower block 337 can be adjusted, that is, the rotation amplitude of the second clamping jaw 334 can be adjusted, thereby being able to adapt to battery cell workpieces 5 of different specifications, and having better adaptability.

[0070] In some embodiments, as Figures 6 to 8 As shown, the second clamping assembly 33 also includes a second buffer block 3310, which is arranged at the end of the second clamping seat 331. The second buffer block 3310 is made of plastic material and has a certain anti-slip effect. At the moment when the second clamping seat 331 clamps the battery workpiece 5, the second buffer block 3310 can also play a buffering role to prevent damage to the battery workpiece 5.

[0071] In some embodiments, as Figure 1 、 Figure 2 and Figure 9As shown, the steering mechanism 2 includes a steering linkage assembly 21 and a steering drive assembly 22. The steering linkage assembly 21 includes a steering linkage seat 211, a steering link 212 and a steering sliding seat 213. The steering linkage seat 211 is arranged on the mounting seat 1, and the steering sliding seat 213 is slidably connected to the mounting seat 1.
