Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing, and particularly relates to an on-line turnover and positioning device for battery cells. Background Art

[0002] During the battery production process, it is necessary to perform laser welding on the A side and the B side of the battery cell. Specifically, first, the conveyor belt transports the battery cell to the first welding station. At this time, the A side of the battery cell faces upward, and the laser welding equipment welds the A side of the battery cell. Then, the conveyor belt continues to transport the battery cell to the turnover station, and the turnover device turns over the battery cell so that the B side of the battery cell faces upward. Next, the conveyor belt continues to transport the battery cell to the second welding station, and the laser welding equipment welds the B side of the battery cell.

[0003] During turnover, the existing turnover device first clamps the battery cell on the conveyor belt, then rotates it 180°, and finally releases the clamp, so that the turned-over battery cell is placed on the conveyor belt and continues to be transported to the next process.

[0004] However, the positions of the battery cells on the conveyor belt after the first welding are inconsistent, resulting in a reduction in the accuracy of the existing turnover device when clamping the battery cells. In addition, after the existing turnover device turns over the battery cell, it directly releases the clamp and the battery cell falls onto the conveyor belt, which will cause the position of the battery cell to change, and further cause the positions of the battery cells transported to the next process to be inconsistent, reducing the welding accuracy of the battery cells. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides an on-line turnover and positioning device for battery cells, which can position the battery cells before and after turnover. Thus, it can improve the accuracy of the battery cell turnover. At the same time, it is convenient for the subsequent process to accurately weld the battery cells on the conveyor belt, ensuring the normal operation of the production line.

[0026] The concept, specific structure and technical effects of the present utility model will be clearly and completely described below in conjunction with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model. In addition, all the connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. Each technical feature in the creation of the present utility model can be combined interactively without mutual contradiction or conflict.

[0027] Referring to Figures 1 to 3 , a core in - line flipping and positioning device provided by an example of the present utility model includes a lifting mechanism 1, a clamping mechanism 2, a flipping mechanism 3 and a positioning mechanism 4.

[0028] Structurally, the lifting mechanism 1 includes a first frame 11, a lifting slide 12 arranged on the first frame 11, and a lifting frame 13 arranged on the lifting slide 12. The clamping mechanism 2 is arranged at the bottom of the lifting frame 13. The clamping mechanism 2 includes a translation component 21 and a clamping jaw 22 arranged on the translation component 21. The translation component 21 is used to drive the clamping jaw 22 to approach or move away from the core, and the clamping jaw 22 is used to clamp the core. The flipping mechanism 3 is arranged between the translation component 21 and the clamping jaw 22, and the flipping mechanism 3 is used to flip the core.

[0029] Furthermore, the positioning mechanism 4 is used to position the core before and after flipping. Specifically, the positioning mechanism 4 includes two limiting components 41 respectively located on both sides of the core. The limiting component 41 is used to limit the side part of the core. The limiting component 41 includes a second frame 411, two first mounting seats 412, a first cylinder 413 arranged on the first mounting seat 412, and a limiting block 414 arranged at the telescopic end of the first cylinder 413. The two first mounting seats 412 are arranged on the second frame 411 in sequence along the conveying direction of the core, and the first cylinder 413 is used to drive the limiting block 414 to approach or move away from the side part of the core.

[0030] When the conveyor belt (not shown in the figure) conveys the battery cell between two oppositely arranged limit blocks 414, the corresponding two first cylinders 413 extend simultaneously so that the two limit blocks 414 approach both sides of the battery cell simultaneously, enabling the positioning of the battery cell before flipping. Then, the lifting slide table 12 drives the lifting frame 13 to descend, the lifting frame 13 drives the clamping mechanism 2 to descend, and the translation assembly 21 drives the jaws 22 to approach the battery cell. The jaws 22 clamp the battery cell, and the two first cylinders 413 located on both sides of the battery cell retract simultaneously. Then, the lifting slide table 12 drives the lifting frame 13 to rise by a certain height, the lifting frame 13 drives the battery cell to rise by a certain height, and the flipping mechanism 3 drives the battery cell to flip 180°. Next, the lifting slide table 12 drives the lifting frame 13 to descend, the jaws 22 release, and the translation assembly 21 moves away from the battery cell, causing the battery cell to fall onto the conveyor belt for continued conveyance. When the flipped battery cell is conveyed between two other oppositely arranged limit blocks 414, the corresponding two first cylinders 413 extend simultaneously so that the two limit blocks 414 approach both sides of the battery cell simultaneously, enabling the positioning of the flipped battery cell. Thus, the accuracy of the battery cell flipping can be improved. At the same time, it is convenient for the subsequent process to accurately weld the battery cells on the conveyor belt, ensuring the normal operation of the production line.

[0031] In some preferred embodiments, a second mounting seat 415 is provided on the second frame 411, and a lifting cylinder 416 is provided on the second mounting seat 415. The telescopic end of the lifting cylinder 416 is connected to the first mounting seat 412.

[0032] It can be understood that when the two oppositely arranged limit blocks 414 approach both sides of the battery cell simultaneously, the two limit blocks 414 clamp the battery cell. Then, the lifting cylinder 416 drives the first mounting seat 412 to rise to drive the battery cell to rise, separating the positioned battery cell from the conveyor belt. Thus, the influence of the conveyor belt on the positioned battery cell can be avoided, ensuring that the clamping mechanism 2 can accurately clamp the battery cell.

[0033] Furthermore, a first linear guide rail 417 is provided between the first mounting seat 412 and the second mounting seat 415. The first linear guide rail 417 is vertically arranged. When the first mounting seat 412 ascends and descends, it can slide along the length direction of the first linear guide rail 417, thereby improving the stability of the first mounting seat 412 during ascending and descending.

[0034] Structurally, the second mounting seat 415 is an L-shaped structure, and the first mounting seat 412 is an inverted L-shaped structure, thereby facilitating the installation of the first linear guide rail 417.

[0035] In some preferred embodiments, the translation assembly 21 includes a second cylinder 211 and a third mounting seat 212 disposed at the telescopic end of the second cylinder 211. The flipping mechanism 3 is mounted on the third mounting seat 212, and the clamping jaws 22 are disposed on the flipping mechanism 3. The second cylinder 211 is mounted at the bottom of the lifting frame 13, and the telescopic direction of the second cylinder 211 is perpendicular to the conveying direction of the battery cell.

[0036] It can be understood that the second cylinder 211 drives the third mounting seat 212 to translate in a direction perpendicular to the conveying direction of the battery cell. The third mounting seat 212 drives the rotating mechanism and the clamping jaws 22 to translate together in a direction perpendicular to the conveying direction of the battery cell. The structure of the second cylinder 211 is simple and easy to achieve translational motion, and the third mounting seat 212 can support the rotating mechanism.

[0037] Further, a second linear guide rail 213 is disposed between the lifting frame 13 and the third mounting seat 212. The length direction of the second linear guide rail 213 is perpendicular to the conveying direction of the battery cell. When the second cylinder 211 drives the third mounting seat 212 to translate, the third mounting seat 212 slides along the length direction of the second linear guide rail 213. Thus, the stability of the third mounting seat 212 during movement can be improved, enabling the clamping jaws 22 to accurately clamp the battery cell.

[0038] In some preferred embodiments, the flipping mechanism 3 includes a motor 31, a speed reducer 32 disposed at the output end of the motor 31, and a rotating plate 33 disposed at the output end of the speed reducer 32. The speed reducer 32 is mounted on the third mounting seat 212, and the clamping jaws 22 are mounted on the rotating plate 33. The rotating plate 33 can support the clamping jaws 22, and the speed reducer 32 can reduce the output speed of the motor 31 and increase the torque. Thus, the load capacity of the rotating plate 33 is improved.

[0039] Further, the clamping jaws 22 include a finger cylinder 221 and two clamping blocks 222. The finger cylinder 221 is mounted on the rotating plate 33, and the two clamping blocks 222 are respectively disposed at the two output ends of the finger cylinder 221. The finger cylinder 221 drives the two clamping blocks 222 to approach each other simultaneously to clamp the side of the battery cell.

[0040] In some preferred embodiments, the number of the translation assemblies 21 is two, and the two translation assemblies 21 are symmetrically disposed along the midline of the lifting frame 13. Correspondingly, a flipping mechanism 3 and clamping jaws 22 are disposed on each translation assembly 21, and the two sides of the battery cell can be clamped simultaneously. Thus, the force on the battery cell during flipping can be made uniform.

[0041] Further, two flipping mechanisms 3 are disposed on the third mounting seat 212, and each flipping mechanism 3 is connected to a clamping jaw 22. The adjacent two clamping jaws 22 are arranged in sequence along the conveying direction of the battery cell, and two battery cells can be clamped and flipped simultaneously. Thus, the production efficiency is greatly improved.

[0042] Correspondingly, two first cylinders 413 are arranged on each first mounting seat 412, and a limiting block 414 is connected to the telescopic end of each first cylinder 413. Adjacent two limiting blocks 414 are arranged in sequence along the conveying direction of the battery cells. Thus, adjacent two battery cells before flipping and adjacent two battery cells after flipping can be positioned simultaneously, greatly improving the production efficiency.

[0043] The above is a specific description of the preferred embodiment of the present utility model, but the present utility model is not limited to the described embodiment. Those skilled in the art can also make various equivalent deformations or substitutions without departing from the spirit of the present utility model, and these equivalent deformations or substitutions are all included within the scope defined by the claims of this application.
