Description

Technical Field

[0002] Lithium-ion batteries must undergo a formation process before use in order to activate the active materials at the positive and negative electrodes of the battery, thereby allowing the battery to reach the optimal state of charge and discharge. The formation step of lithium-ion batteries is an important stage in battery manufacturing. The quality of the formation is related to many aspects of the battery quality, such as capacity, cycle life, and safety performance.

[0003] In the lithium battery production process, formation processing is a key link. In order to improve the formation efficiency, multi-layer batteries need to be formed at one time in the same fixture. Under the current operation mode, operators need to manually install single cells one by one on the shelf, and after completing the single-layer clamping, stack them vertically to form a formation module, and then transfer the entire module to the formation equipment for charging and discharging activation. However, the above process has a high proportion of manual operation. It is difficult to ensure the positioning accuracy when placing the battery tray, and repeated adjustments are required, which not only slows down the production rhythm, but also increases operator fatigue, resulting in cumbersome manual operation, heavy workload, and low production efficiency.

[0039] For example, certain terms are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in names as a way to distinguish components, but rather use the difference in functions of components as the criterion for distinction. As used throughout the specification and claims, the term "comprising" is an open-ended term and should be interpreted as "including but not limited to". "Substantially" means within an acceptable error range. Those skilled in the art can solve technical problems within a certain error range and basically achieve the technical effect.

[0040] In addition, terms such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0041] In an invention, unless otherwise clearly defined and limited, terms such as "installed", "connected", "joined", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] The following will be combined with the attached Figures 1 - 21 The technical solutions in the embodiments of the present invention will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without any creative work shall fall within the protection scope of the present invention.

[0043] Please refer to Figures 1 - 21 , the battery automated formation production line 100 of the embodiment of the present invention includes a loading and unloading buffer device 10, a transfer feeding device 20, and a formation device 30. The loading and unloading buffer device 10 has a plurality of first storage positions arranged in a stacked manner. The transfer feeding device 20 has a plurality of second storage positions arranged in a stacked manner. The formation device 30 includes a formation fixture 31. The formation fixture 31 has a plurality of clamping positions. A plurality of the first storage positions and a plurality of the clamping positions are arranged in one-to-one correspondence with a plurality of the second storage positions. The transfer feeding device 20 is slidably arranged between the loading and unloading buffer device 10 and the formation fixture 31.

[0044] Compared with the prior art, in the battery automated formation production line 100 according to the embodiment of the present invention, through the combined use of the loading and unloading buffer device 10, the transfer and feeding device 20, and the formation device 30, the loading and unloading buffer device 10 is used to buffer the tray 300 carrying the battery 200 to be formed, the transfer and feeding device 20 is used to transfer the tray 300 of the loading and unloading buffer device 10 into the formation device 30, or extract the tray 300 carrying the formed battery 200 from the formation device 30. The formation device 30 includes a formation fixture 31, and the formation fixture 31 has a plurality of clamping positions. During the formation process of the battery 200, after the transfer and feeding device 20 transfers the tray 300 carrying the battery 200 to be formed from the first storage position of the loading and unloading buffer device 10 to the second storage position, the transfer and feeding device 20 moves to the formation fixture 31 and transfers the tray 300 carrying the battery 200 to be formed from the second storage position to the clamping position. The clamping position clamps the tray 300 carrying the battery 200 to be formed for formation. There is no need for manual loading and unloading of the battery 200 during the formation process of the battery 200, which saves labor costs, reduces the error rate of manual formation operations, improves the yield rate, effectively realizes the automated production operation of the battery 200 formation process, improves the battery 200 formation efficiency, and improves the automation level of the battery 200 formation. In addition, since the plurality of the first storage positions and the plurality of the clamping positions are arranged in one-to-one correspondence with the plurality of the second storage positions, it effectively enables the transfer and feeding device 20 to transfer the tray 300 of the loading and unloading buffer device 10 to the formation fixture 31 at one time, effectively improving the efficiency of the transferred tray 300.

[0045] In some embodiments, the formation device 30 further includes a first frame 32 and a vertical and horizontal flipping assembly 33. The formation fixture 31 is rotatably disposed on the first frame 32. Along the z-axis direction, the vertical and horizontal flipping assembly 33 is disposed on at least one side of the first frame 32. The vertical and horizontal flipping assembly 33 is connected to the formation fixture 31. The formation fixture 31 has a first state and a second state. When in the first state, a plurality of the clamping positions are spaced along the y-axis direction on the formation fixture 31. When in the second state, the formation fixture 31 is flipped by 90°, and a plurality of the clamping positions are spaced along the x-axis direction on the formation fixture 31. By the combined use of the first frame 32 and the vertical and horizontal flipping assembly 33, the vertical and horizontal flipping assembly 33 is used to assist the rotation of the formation fixture 31 on the first frame 32. When in the first state, that is, when the formation fixture 31 is in an upright state, a plurality of clamping positions are spaced along the y-axis direction. A plurality of clamping positions are arranged in one-to-one correspondence with a plurality of second storage positions, and each clamping position and its corresponding second storage position are arranged parallel to each other along the x-axis direction, effectively facilitating the transfer feeding mechanism to transfer the tray 300 from the second storage position to the clamping position. When in the second state, that is, when the formation fixture 31 is in a lying state, the vertical and horizontal flipping assembly 33 drives the formation fixture 31 to flip by 90°, and a plurality of clamping positions are spaced along the x-axis direction. Effectively, the formation fixture 31 drives the battery 200 to be formed to flip, so that the battery 200 to be formed is vertically arranged, and the formation fixture 31 starts to form. The electrolyte uniformly penetrates the pores of the electrode plate under the action of gravity, effectively improving the electrolyte infiltration effect, thereby improving the formation yield of the battery 200.

[0046] In some embodiments, the vertical and horizontal flipping assembly 33 includes a first motor 331, a turbine speed reducer 332, a first gear 333 and a second gear 334. The turbine speed reducer 332 is disposed on the first frame 32. The turbine speed reducer 332 has an input end and an output end. The output shaft of the first motor 331 is connected to the input end of the turbine speed reducer 332. The first gear 333 is connected to the output end of the turbine speed reducer 332. The second gear 334 is disposed on the forming fixture 31. The first gear 333 and the second gear 334 are meshed. Through the combined use of the first motor 331, the turbine speed reducer 332, the first gear 333 and the second gear 334, the first motor 331 is connected to the first gear 333 through the turbine speed reducer 332. The turbine speed reducer 332 can effectively reduce the speed and increase the torque, converting the high-speed and low-torque power of the first motor 331 into the low-speed and high-torque power suitable for the flipping requirement, making the vertical and horizontal flipping process stable and powerful, avoiding the situation of flipping jamming or incomplete flipping due to insufficient power, and ensuring the stability and reliability of the equipment operation. Through the meshing of the first gear 333 and the second gear 334, the flipping angle and speed of the forming fixture 31 can be accurately controlled effectively. At the same time, the consistency of each flipping action can be ensured, and the standardization degree of the production process can be improved.

[0047] In some embodiments, the first frame 32 includes a base 321 and two mounting seats 322, the formation fixture 31 includes a second frame 311, a driving member 312, a layer 313 and a push plate 314, along the z-axis direction, the two mounting seats 322 are spaced apart on the base 321, and a rotating shaft 315 is provided on both sides of the second frame 311. The second gear 334 is provided on the rotating shaft 315 on at least one side of the second frame 311, and the second frame 311 is provided between the two mounting seats 322. The rotating shafts 315 on both sides of the frame are arranged in a one-to-one correspondence with the two mounting seats 322, and the rotating shafts 315 and the corresponding mounting seats 322 are rotatably connected. A plurality of layer plates 313 are provided, and a plurality of the layer plates 313 are spaced apart in the second frame 311. The push plate 314 is provided between the top of the frame and the layer plate 313, and between the push plate 314 and the layer plate 313, The cam 314 is provided with a first end 342 which is adapted to engage the first and second guide rails 341 and 342 and to engage the second and second guide rails 342. The cam 314 is provided with a first end 342 which is adapted to engage the first and second guide rails 341 and 342 and to engage the second and second guide rails 342.

[0048] Through the coordinated use of the machine base 321, the mounting base 322, the second frame 311, the driving member 312, the layer plate 313 and the push plate 314, the rotating shafts 315 on both sides of the second frame 311 are rotatably connected to the mounting base 322, and the gear transmission in the vertical and horizontal flipping assembly 33 is cooperated to enable the second frame 311 to be converted from vertical to horizontal, thereby realizing the vertical and horizontal conversion of the forming fixture 31. Multiple layer plates 313 are arranged at intervals in the second frame 311, and clamping positions are formed between the push plate 314 and the layer plates 313, as well as between two adjacent layer plates 313. The driving member 312 drives the push plate 314 to move forward or backward along the z-axis direction through the output shaft. During the formation process, after the tray 300 carrying the battery 200 to be formed is placed on the layer plate 313, the driving member 312 drives the push plate 314 to squeeze the layer plate 313 forward, thereby clamping and fixing the battery 200 to be formed, effectively preventing the battery 200 to be formed from falling from the layer plate 313 during the switching of the second frame 311 from the first state to the second state. At the same time, pressure can be applied to the battery 200 when the battery 200 is formed, ensuring the excellent formation rate of the battery 200.

[0049] Through the setting of the conductive part, the conductive part includes a first guide rod 341 and a second guide rod 342. The push plate 314 is slidably connected to the first guide rod 341 through a sliding sleeve 316. The push plate 314 and the layer plate 313 are slidably connected to the second guide rod 342 through a through hole, which effectively guides the movement of the push plate 314 and the layer plate 313, limits the offset and shaking of the push plate 314 and the layer plate 313 during the movement, ensures the high precision and stability of the clamping operation, and further improves the processing quality and reliability of the equipment.

[0050] It is understandable that the driving member 312 is a servo motor or a cylinder.

[0051] In some embodiments, the formation device 30 also includes a limiting assembly 35, which includes a cross bar 351, a first buffer 352, a second buffer 353, a first sensor 354 and a second sensor 355. Along the z-axis direction, one end of the cross bar 351 is adjacent to one side of the first frame 32, and the other end of the cross bar 351 is arranged on the other side of the first frame 32. The first buffer 352, the second buffer 353, the first sensor 354 and the second sensor 355 are all arranged on the cross bar 351. When in the first state, the sensing part of the first sensor 354 corresponds to the bottom of the formation fixture 31, and the first buffer 352 abuts the side of one end of the formation fixture 31. When in the second state, the sensing part of the second sensor 355 corresponds to the top of the formation fixture 31, and the second buffer abuts the side of the other end of the formation fixture 31.

[0052] Through the setting of the limiting component 35, the limiting component 35 is used to limit the formation fixture 31 when the formation fixture 31 is flipped to the first state and the second state, so that the formation fixture 31 can accurately switch to the corresponding position. The limiting component 35 includes a cross bar 351, a first buffer portion 352, a second buffer portion 353, a first sensor 354 and a second sensor 355. When the formation fixture 31 is flipped and switched to the first state, the first buffer portion 352 abuts against the side portion of one end of the formation fixture 31. When the formation fixture 31 is flipped and switched to the second state, the second buffer portion 353 abuts against the side portion of the other end of the formation fixture 31. Both the first buffer portion 352 and the second buffer portion 353 effectively absorb and disperse the impact force generated when the fixture reaches the limit position through their own buffering characteristics, avoiding structural damage caused by rigid collision between the fixture and the machine frame, protecting key components such as the formation fixture 31 and the first machine frame 32, extending the overall service life of the equipment, and reducing the maintenance cost and downtime risk. At the same time, the first buffer portion 352 and the second buffer portion 353 can also play a role in stable support after the formation fixture 31 is in place, suppressing the shaking and vibration generated by the formation fixture 31 due to inertia.

[0053] In addition, the first sensor 354 and the second sensor 355 respectively correspond to the bottom and the top of the formation fixture 31. During the flipping process of the fixture, its position state can be monitored in real time. When the fixture reaches the preset position, the sensors quickly sense and feedback signals to control the equipment to stop operating, ensuring that the fixture accurately stays in the first state or the second state with extremely small error, providing an accurate position basis for subsequent processes such as processing and detection, and improving the consistency and qualified rate of product production.

[0054] In some embodiments, the limiting component 35 further includes a first air cylinder 356. The first air cylinder 356 is arranged on the first machine frame 32, and the first air cylinder 356 is located between the first machine frame 32 and the formation fixture 31. When in the first state, the output shaft of the first air cylinder 356 abuts against the bottom of the formation fixture 31. Through the setting of the first air cylinder 356, when the formation fixture 31 is in the first state, the output shaft of the first air cylinder 356 abuts against the bottom of the formation fixture 31, providing an additional supporting force for the formation fixture 31. Compared with only relying on the support of the mounting seat 322 and the rotating shaft 315, the top support effect of the first air cylinder 356 can effectively disperse the weight of the formation fixture 31 and the workpiece it carries, reduce the stress load on the mounting seat 322 and the rotating shaft 315, reduce the wear caused by long-term stress, enhance the stability of the overall structure, avoid unstable situations such as sinking and shaking of the formation fixture 31 during operation, and ensure the reliability of equipment operation.

[0055] It is understandable that the expansion and contraction of the first cylinder 356 can be accurately adjusted by controlling the air pressure, and the size of the supporting force can be flexibly adjusted according to the formation fixture 31 and the workpiece of different specifications and weights. During the operation of the equipment, if the position of the formation fixture 31 is slightly offset due to factors such as vibration and load variation, the first cylinder 356 can respond in real time and adjust the expansion and contraction of the output shaft, perform dynamic compensation, and make the formation fixture 31 remain in the ideal working position. This self-adaptive ability effectively improves the adaptability of the equipment to complex working conditions, reduces the processing error caused by external interference, and improves the production quality of the product. After the sensor detects that the formation fixture 31 arrives in the first state, the control system immediately issues an instruction so that the output shaft of the first cylinder 356 extends out to provide support; and when the formation fixture 31 needs to flip, the output shaft of the first cylinder 356 can be retracted in time, without affecting the flipping action, and the whole process does not require manual intervention, thereby improving the automation level and production efficiency of the equipment.

[0056] In some embodiments, the first frame 32 has an insulation chamber 323, the formation fixture 31 and the vertical / horizontal turning assembly 33 are both disposed within the insulation chamber 323, an air outlet 324 is disposed at the top of the first frame 32, an air inlet 325 is disposed at the bottom of the first frame 32, and an opening 326 is disposed at the front side of the first frame 32. The air outlet 324, the air inlet 325, and the opening 326 are all connected to the insulation chamber 323, wherein the first frame 32 is provided with an exhaust fan 36 at the air outlet 324, the first frame 32 is provided with an opening and closing structure 37 at the air inlet 325, and the first frame 32 is provided with an automatic door 38 at the opening 326. By disposing the insulation chamber 323, the formation fixture 31 and the vertical / horizontal turning assembly 33 are both disposed within the insulation chamber 323, and the insulation chamber 323 can effectively stabilize the environment of the battery 200 during formation, thereby ensuring the formation effect of the battery 200. The exhaust fan 36 cooperates with the air outlet 324 to forcibly exhaust the indoor hot air, while the opening and closing structure 37 of the air inlet 325 allows external air to be introduced as needed. The two functions work together to regulate air circulation, effectively controlling the temperature within the insulation chamber 323 and effectively preventing temperature fluctuations from affecting the formation effect. Through the cooperation of the opening 326 and the automatic door 38, when the automatic door 38 is open, the transfer and feeding mechanism transfers the tray 300 to or removes it from the formation fixture 31 through the opening 326. When the automatic door 38 is closed, the formation fixture 31 proceeds to form, effectively ensuring the formation effect of the batteries 200.

A plurality of the first storage positions are arranged at intervals on the storage rack 11. Along the x-axis direction, one end of the conveyor belt 12 extends to the bottom of the storage rack 11. Along the z-axis direction, the two lifting units 13 are oppositely arranged on both sides of the storage rack 11. Each lifting unit 13 includes a second cylinder 131, a lifting part 132, a third cylinder 133, and a supporting part 134. The second cylinder 131 is arranged on the top of the storage rack 11. The output shaft of the second cylinder 131 is connected to the lifting part 132 along the y-axis direction. The third cylinder 133 is arranged on one side of the storage rack 11.

The supporting part 134 is arranged on the side of the lifting part 132 facing the storage rack 11. Through the combined use of the storage rack 11, the conveyor belt 12, and the lifting units 13, along the x-axis direction, one end of the conveyor belt 12 extends to the bottom of the storage rack 11, effectively enabling the tray 300 carrying the battery 200 to be formed to be transported to the bottom of the storage rack 11 through the conveyor belt 12. Along the z-axis direction, the two lifting units 13 are oppositely arranged on both sides of the storage rack 11. The two lifting units 13 cooperate to lift and place the tray 300 carrying the battery 200 to be formed from the conveyor belt 12 into the storage space, effectively buffering the tray 300 carrying the battery 200 to be formed on the conveyor belt 12, effectively alleviating the pressure on the transportation system for transporting the battery 200 to be formed, and avoiding blockage or idling of the transportation system.

[0058] Through the combined use of the second cylinder 131, the lifting part 132, the third cylinder 133, and the supporting part 134, the second cylinder 131 can drive the lifting part 132 and the supporting part 134 to rise or fall along the y-axis direction, and the third cylinder 133 can drive the lifting part 132 and the supporting part 134 to move forward or backward along the z-axis direction. When the conveyor belt 12 transports the tray 300 carrying the battery 200 to be formed to the bottom of the storage rack 11, the third cylinder 133 drives the lifting part 132 and the supporting part 134 to move forward, and the supporting part 134 holds the tray 300. Then, the second cylinder 131 drives the lifting part 132 and the supporting part 134 to rise. After placing the tray 300 carrying the battery 200 to be formed into the storage space, the third cylinder 133 drives the lifting part 132 and the supporting part 134 to move backward, and the second cylinder 131 drives the lifting part 132 and the supporting part 134 to descend, so that the lifting part 132 and the supporting part 134 are reset. Repeat the above operations until the first storage position is filled, effectively realizing the buffering of the battery 200 to be formed. In addition, there is no need to manually place the battery 200 to be formed into the storage rack 11, reducing the time and error of manual operation and effectively improving the automation degree of the loading and unloading buffer device 10.

[0059] In some embodiments, along the z-axis direction, fourth cylinders 14 are provided on both sides of the storage rack 11. The output shafts of the fourth cylinders 14 are connected to moving brackets 15. A plurality of storage platforms 16 are provided on the side of the moving bracket 15 facing away from the fourth cylinder 14. The storage platforms 16 on both sides of the storage rack 11 form a first storage position. A plurality of supporting portions 134 are provided, and the plurality of supporting portions 134 are arranged at intervals along the y-axis direction on the lifting portion 132. The plurality of supporting portions 134 are arranged in one-to-one correspondence with the plurality of first storage positions. Through the coordinated use of the fourth cylinder 14, the moving bracket 15 and the storage platform 16, the fourth cylinder 14 is used to drive the moving bracket 15 and the storage platform 16 to move forward or backward along the z-axis direction, effectively enabling the adjustment of the interval between the storage platforms 16 on both sides of the storage rack 11, thereby adjusting the size of the storage position so that the storage position can be compatible with trays 300 or batteries 200 to be formed of various specifications.

[0060] When the lifting unit 13 lifts the tray 300 carrying the battery 200 to be formed above the target storage layer, after the fourth cylinder 14 drives the storage platform 16 to move forward and hold the tray 300, the third cylinder 133 drives the lifting portion 132 and the supporting portion 134 to move backward, and the second cylinder 131 drives the lifting portion 132 and the supporting portion 134 to descend. The lifting portion 132 and the supporting portion 134 are reset and wait to lift the next tray 300 carrying the battery 200 to be formed. Effectively realize the buffering of the battery 200 to be formed and improve the automation degree of the loading and unloading buffering device 10.

[0061] By setting the multiple supporting parts 134 in one-to-one correspondence with the multiple first storage positions, when storing the next tray 300 carrying the battery 200 to be formed, the third cylinder 133 drives the lifting part 132 and the supporting part 134 forward. The supporting part 134 correspondingly holds the tray 300 on the conveyor belt 12 and the storage platform 16. The fourth cylinder 14 drives the storage platform 16 to move backward to make way for the rising of the tray 300 on the conveyor belt 12. The second cylinder 131 drives the lifting part 132 and the supporting part 134 to rise. After lifting the tray 300 above the target storage layer, the fourth cylinder 14 drives the storage platform 16 to move forward and hold the tray 300. Then, the third cylinder 133 drives the lifting part 132 and the supporting part 134 to move backward, and the second cylinder 131 drives the lifting part 132 and the supporting part 134 to descend. The lifting part 132 and the supporting part 134 return to their original positions, waiting to lift the next tray 300 carrying the battery 200 to be formed. Through the mutual cooperation of the second cylinder 131, the third cylinder 133 and the fourth cylinder 14, the transfer of a single tray 300 from the conveyor belt 12 to the target storage layer of the storage rack 11 is effectively realized. When the conveyor belt 12 conveys a new tray 300, the storage platform 16 moves backward through the fourth cylinder 14 to vacate a vertical rising space, avoiding mechanical interference with the lifting supporting part 134 and ensuring the smooth operation of the multi-layer storage positions during high-density storage.

[0062] It can be understood that the supporting part 134 correspondingly holds the tray 300 on the conveyor belt 12 and the storage platform 16. That is, among the multiple supporting parts 134, the supporting part 134 corresponding to the tray 300 on the transportation unit holds the tray 300 on the transportation unit; among the multiple supporting parts 134, the supporting part 134 corresponding to the tray 300 on the storage platform 16 holds the tray 300 on the storage platform 16.
