Description

Technical Field

[0001] The present invention belongs to the technical field of battery production and manufacturing, and particularly relates to an automated battery production line. Background Art

[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.

[0051] For example, certain words 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. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0052] Furthermore, the terms “first,” “second,” etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance.

[0053] In the present invention, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0054] The following will be combined with the Figures 1 to 21 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0055] See also Figures 1 to 21 The battery automated production line 100 of an embodiment of the present invention includes a loading and unloading buffer device 10, a transfer and 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 and feeding device 20 has a plurality of second storage positions arranged in a stacked manner, and the formation device 30 includes a formation clamp 31. The formation clamp 31 has a plurality of clamping positions, and the plurality of first storage positions and the plurality of clamping positions are arranged in a one-to-one correspondence with the plurality of second storage positions. The transfer and feeding device 20 can be slidably arranged between the loading and unloading buffer device 10 and the formation clamp 31.

[0056] Compared with the prior art, the battery automatic forming production line 100 of the embodiment of the present invention is used in conjunction with the loading and unloading buffer device 10, the transfer feeding device 20 and the formation device 30. The loading and unloading buffer device 10 is used to cache the tray 300 carrying the battery 200 to be formed, and the transfer feeding device 20 is used to transfer the tray 300 of the loading and unloading buffer device 10 to the formation device 30, or to 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 multiple clamping positions. During the formation process of the battery 200, the battery 200 is loaded on the tray 300 to be formed by the transfer feeding device 20. After the tray 300 of the battery 200 is transferred from the first storage position of the loading and unloading buffer device 10 to the second storage position, the transfer 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 operation of loading and unloading 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 all set in one-to-one correspondence with the plurality of the second storage positions, the transfer feeding device 20 can effectively 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.

[0057] In some embodiments, the formation device 30 also includes a first frame 32 and a vertical and horizontal flipping assembly 33. The formation fixture 31 is rotatably arranged on the first frame 32. Along the z-axis direction, at least one side of the first frame 32 is provided with the vertical and horizontal flipping assembly 33. 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 apart along the y-axis direction on the formation fixture 31; when in the second state, the formation fixture 31 flips 90°, and a plurality of the clamping positions are spaced apart along the x-axis direction on the formation fixture 31. Through the coordinated use of the first frame 32 and the vertical-horizontal flipping assembly 33, the vertical-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, the formation fixture 31 is in the upright state, multiple clamping positions are arranged at intervals along the y-axis direction, and multiple clamping positions are arranged in a one-to-one correspondence with multiple second storage positions, and each clamping position and the corresponding second storage position are arranged parallel to the x-axis direction, which effectively facilitates the transfer and feeding mechanism to transfer the tray 300 from the second storage position to the clamping position. When in the second state, that is, the formation fixture 31 is in a lying state, the vertical-horizontal flipping assembly 33 drives the formation fixture 31 to flip 90°, and multiple clamping positions are arranged at intervals along the x-axis direction, effectively driving the battery 200 to be formed to flip through the formation fixture 31, so that the battery 200 to be formed is arranged vertically, and the formation fixture 31 begins to form. The electrolyte is evenly penetrated into the pores of the electrode under the action of gravity, effectively improving the electrolyte infiltration effect, thereby improving the formation rate of the battery 200.

[0058] In some embodiments, the vertical and horizontal flip assembly 33 includes a first motor 331, a turbine reduction box 332, a first gear 333, and a second gear 334. The turbine reduction box 332 is disposed on the first frame 32. The turbine reduction box 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 reduction box 332. The first gear 333 is connected to the output end of the turbine reduction box 332. The second gear 334 is disposed on the formation fixture 31, and the first gear 333 and the second gear 334 are meshed. Through the coordinated use of the first motor 331, the turbine reduction box 332, the first gear 333 and the second gear 334, the first motor 331 is connected to the first gear 333 through the turbine reduction box 332. The turbine reduction box 332 can effectively reduce the speed and increase the torque, converting the high speed and low torque power of the first motor 331 into low speed and high torque power suitable for flipping requirements, making the vertical and horizontal flipping process smooth and powerful, avoiding the situation where the flip is stuck or not in place due to insufficient power, and ensuring the stability and reliability of the equipment operation. By meshing the first gear 333 and the second gear 334 , the flipping angle and speed of the formation fixture 31 can be effectively and accurately controlled. At the same time, the consistency of each flipping action can be ensured, thereby improving the standardization of the production process.

[0059] 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 plate 313 and a push plate 314, along the z-axis direction, the two mounting seats 322 are spaced apart on the base 321, a rotating shaft 315 is provided on both sides of the second frame 311, and the second gear 334 is provided on the rotating shaft 315 on at least one side of the second frame 311. The second frame 311 is placed between the two mounting seats 322, and the rotating shafts 315 on both sides of the second frame 311 are arranged in a one-to-one correspondence with the two mounting seats 322. The rotating shafts 315 and the corresponding mounting seats 322 are rotatably connected. The layer plates 313 are provided with a plurality of layers 313, and the plurality of layer plates 313 are arranged at intervals in the second frame 311. The push plate 314 is provided between the top of the second frame 311 and the layer plates 313. The cam 314 is a block diagram of a block diagram of a cam 314 for camming a user, wherein the cam 314 is a block diagram of a block diagram of a cam 314 for camming a user, wherein the cam 314 is a block diagram of a block diagram of a cam 314 for camming a user, wherein the cam 314 is a block diagram of a block diagram of a cam 314 for camming a user, wherein the cam 314 is a block diagram of a block diagram of a cam 314 for camming a user,

[0060] 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.

[0061] 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.

[0062] It can be understood that the driving member 312 is a servo motor or a cylinder.

[0063] 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 arranged on 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 352 abuts the side of the other end of the formation fixture 31.

[0064] 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 be accurately switched to the corresponding position. The limit assembly 35 includes a cross bar 351, a first buffer 352, a second buffer 353, a first sensor 354, and a second sensor 355. The first buffer 352 abuts the side of one end of the fixture 31 when the fixture 31 is flipped and switched to the first state. The second buffer 353 abuts the side of the other end of the fixture 31 when the fixture 31 is flipped and switched to the second state. The first buffer 352 and the second buffer 353 effectively absorb and disperse the impact force generated by the fixture 31 when it reaches the limit position through its own buffering characteristics, avoiding structural damage caused by rigid collision between the fixture 31 and the first frame 32, protecting key components such as the fixture 31 and the first frame 32, extending the service life of the entire equipment, reducing maintenance costs and downtime risks. At the same time, the first buffer 352 and the second buffer 353 can also play a stabilizing supporting role after the fixture 31 is in place, suppressing the shaking and vibration of the fixture 31 due to inertia.

[0065] Furthermore, the first sensor 354 and the second sensor 355 correspond to the bottom and top of the formation fixture 31, respectively, and monitor its position in real time during the fixture's rotation process. When the fixture reaches the preset position, the sensors quickly sense and feedback a signal, controlling the device to stop, ensuring that the fixture remains precisely in the first or second position with minimal error. This provides a precise positioning basis for subsequent processing and testing, improving product consistency and yield.

[0066] In some embodiments, the limiting assembly 35 further includes a first cylinder 356, which is arranged on the first frame 32 and is located between the first frame 32 and the formation fixture 31. When in the first state, the output shaft of the first cylinder 356 abuts the bottom of the formation fixture 31. By the provision of the first cylinder 356, when the formation fixture 31 is in the first state, the output shaft of the first cylinder 356 abuts the bottom of the formation fixture 31, providing additional supporting force for the formation fixture 31. Compared to relying solely on the support of the mounting base 322 and the rotating shaft 315, the supporting effect of the first cylinder 356 can effectively disperse the weight of the formation fixture 31 and its bearing workpiece, reduce the load of the mounting base 322 and the rotating shaft 315, reduce the wear caused by long-term stress, enhance the stability of the overall structure, avoid the formation fixture 31 from sinking, shaking and other unstable situations during operation, and ensure the reliability of the equipment operation.

[0067] 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.

[0068] 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.

[0069] In some embodiments, the loading and unloading buffer device 10 includes a storage rack 11, a conveyor belt 12 and two lifting units 13. Multiple 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 relatively arranged on both sides of the storage rack 11. Each of the lifting units 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 at the top of the storage rack 11, and 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 output shaft of the third cylinder 133 is connected to the side of the lifting part 132 away from the storage rack 11 along the z-axis direction. The supporting part 134 is arranged on the side of the lifting part 132 facing the storage rack 11. By using the storage rack 11, the conveyor belt 12 and the lifting unit 13 in coordination, one end of the conveyor belt 12 extends to the bottom of the storage rack 11 along the x-axis direction, effectively enabling the tray 300 carrying the batteries 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 relatively arranged on both sides of the storage rack 11. The two lifting units 13 cooperate to lift the tray 300 carrying the batteries 200 to be formed from the conveyor belt 12 and place it in the storage space, effectively caching the tray 300 carrying the batteries 200 to be formed on the conveyor belt 12, effectively alleviating the pressure of the transportation system in transporting the batteries 200 to be formed, and avoiding blockage or idling of the transportation system.

[0070] By the coordinated 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 batteries 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 downward through the supporting part 134. The supporting portion 134 supports the tray 300, and then the second cylinder 131 drives the lifting portion 132 and the supporting portion 134 to rise. After the tray 300 carrying the battery 200 to be formed is placed in the storage space, 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, so that the lifting portion 132 and the supporting portion 134 are reset, and the above operation is repeated until the first storage position is filled, effectively achieving the caching of the battery 200 to be formed. In addition, there is no need to manually place the battery 200 to be formed in the storage rack 11, which reduces the time and error of manual operation and effectively improves the automation level of the loading and unloading cache device 10.

[0071] In some embodiments, a fourth cylinder 14 is provided on both sides of the storage rack 11 along the z-axis. The output shaft of the fourth cylinder 14 is connected to a movable bracket 15. A plurality of storage platforms 16 are provided on the side of the movable 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 spaced apart along the y-axis on the lifting portion 132. The plurality of supporting portions 134 are arranged one-to-one with the plurality of first storage positions. Through the coordinated use of the fourth cylinder 14, the movable bracket 15, and the storage platforms 16, the fourth cylinder 14 is used to drive the movable bracket 15 and the storage platforms 16 forward or backward along the z-axis, effectively making the spacing between the storage platforms 16 on both sides of the storage rack 11 adjustable, thereby adjusting the size of the storage positions, so that the storage positions can accommodate trays 300 or batteries 200 to be formed of various specifications.

[0072] When the lifting unit 13 lifts the tray 300 carrying the batteries 200 to be formed to the top of the target storage layer, the fourth cylinder 14 drives the storage platform 16 to move forward and support the tray 300. Then, the third cylinder 133 drives the lifting part 132 and the supporting part 134 to move backward. 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 position and wait for the next tray 300 carrying the batteries 200 to be formed to be lifted. This effectively achieves the caching of the batteries 200 to be formed and improves the automation level of the loading and unloading caching device 10.

[0073] By arranging a plurality of supporting parts 134 and a plurality of first storage positions in a one-to-one correspondence, when the next tray 300 carrying the battery 200 to be formed is stored, the third cylinder 133 drives the lifting part 132 and the supporting part 134 forward, and the supporting part 134 correspondingly supports the conveyor belt 12 and the tray 300 on the storage platform 16. The fourth cylinder 14 drives the storage platform 16 to move backward to avoid the rising of the tray 300 on the conveyor belt 12. The second cylinder 131 drives the lifting unit 132 and the supporting unit 134 upward, lifting the tray 300 to the top of the target storage layer. The fourth cylinder 14 drives the storage platform 16 forward to support the tray 300. The third cylinder 133 drives the lifting unit 132 and the supporting unit 134 backward. The second cylinder 131 drives the lifting unit 132 and the supporting unit 134 downward. The lifting unit 132 and the supporting unit 134 return to their original position, ready to lift the next tray 300 carrying the batteries 200 to be formed. The coordinated operation of the second cylinder 131, the third cylinder 133, and the fourth cylinder 14 effectively transfers a single tray 300 from the conveyor belt 12 to the target storage layer of the storage rack 11. When the conveyor belt 12 delivers a new tray 300, the storage platform 16 moves backward via the fourth cylinder 14 to clear vertical space for upward movement, avoiding mechanical interference with the lifting supporting unit 134, thus ensuring smooth operation of the multi-layer storage space during high-density storage.

[0074] It is understood that the supporting portions 134 support the conveyor belt 12 and the pallets 300 on the storage platform 16 . That is, among the plurality of supporting portions 134 , the supporting portions 134 corresponding to the pallets 300 on the transport unit support the pallets 300 on the transport unit; and among the plurality of supporting portions 134 , the supporting portions 134 corresponding to the pallets 300 on the storage platform 16 support the pallets 300 on the storage platform 16 .

The driving component 221 is used to drive the sliding seat 2221 and the clamping part 2222 of the grabbing component 222 to advance or retreat along the x-axis direction. The clamping part 2222 can grab and transfer the tray 300 carrying the battery 200 to be formed from the shelf through the clamping position. The multiple clamping positions are arranged along the y-axis direction, and the multiple clamping positions are arranged one-to-one with the multiple first storage positions, so that the clamping part 2222 can effectively grab and transfer the multiple trays 300 arranged in parallel on the storage rack 11 at the same time, and realize the one-time transfer of the entire row of trays 300 from the storage rack 11 to the formation fixture 31, thereby effectively improving the efficiency of transferring the trays 300.

The fifth cylinder 2223 drives the connecting seat 2224 and the clamping strip 2225 to move along the z-axis direction. When clamping the pallet 300, the clamping strips 2225 of the two clamping parts 2222 approach each other to form a clamping structure. When releasing the pallet 300, the clamping strips 2225 of the two clamping parts 2222 move away from each other, effectively realizing the grasping and release of the pallet 300 by the clamping part 2222.
