Description

Technical Field

[0001] This invention belongs to the field of lithium battery production technology, and relates to an intelligent production logistics system for formation and capacity testing, particularly an intelligent production logistics system for formation and capacity testing of new energy lithium batteries. Background Technology

[0002] Formation and capacity testing are core processes in the later stages of lithium battery production, directly affecting battery performance, consistency, and safety. This process includes the initial charging (formation), discharging, and capacity testing of the cells, typically taking tens of hours, and the cells need to be moved between multiple stations such as resting, charging / discharging, and testing.

[0003] Currently, many lithium battery production lines still face the following problems in their formation and capacity-building logistics: low automation, heavy reliance on manual handling and loading / unloading, resulting in low efficiency, safety risks, and potential damage to the cell appearance; poor production flexibility, slow scheduling response and low equipment utilization during order changes or equipment failures; efficiency bottlenecks, with the loading / unloading process strongly coupled with the long-term static formation process, leading to long logistics waiting times and low equipment utilization; and low space utilization, with traditional linear layouts or centralized buffering methods occupying a large amount of space, and frequent local congestion or idle equipment due to unintelligent scheduling.

[0004] Based on this, we propose an intelligent production logistics system for the formation and capacity testing of new energy lithium batteries. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an intelligent production logistics system for the formation and capacity testing of new energy lithium batteries. The technical problem this invention aims to solve is: how to achieve unmanned, intelligent, and highly consistent production of lithium battery processing procedures through a continuous automated process of "feeding → physical shaping and initial screening → buffering and supply → electrochemical formation → buffering and output → attitude adjustment → cleaning and precision testing → automatic sorting → finished product packaging and unloading".

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A smart production logistics system for the formation and capacity testing of new energy lithium batteries includes a feeding mechanism, a leveling mechanism, a formation mechanism, an OCV detection mechanism, and a discharging mechanism. The feeding mechanism is located to the left of the leveling mechanism, and the formation mechanism is located in front of the leveling mechanism. The leveling mechanism includes a leveling housing with an upper cover on top. A main control unit is mounted on the upper cover. A material conveyor, a feeding conveyor, and a leveling and handling assembly are located on the upper left side of the leveling housing. The material conveyor and the feeding conveyor are located inside the leveling and handling assembly. A leveling and pressing assembly, a transverse pushing assembly, and two sensor gratings are located in the upper center of the leveling housing. The transverse pushing assembly is located below the leveling and pressing assembly, and the two sensor gratings are located on the front and rear sides of the leveling and pressing assembly, respectively. The right side of the flattening machine is equipped with a material conveyor and a waste conveyor. The upper right side of the flattening machine is equipped with a horizontal displacement mechanism, which is located above the material conveyor and the waste conveyor. The formation mechanism includes a formation machine box, a formation conveyor located behind the formation machine box, and a formation material handling assembly located above the formation machine box. Above the formation conveyor are two formation storage assemblies and two formation pressing assemblies. The two formation storage assemblies are located on the left and right sides of the two formation pressing assemblies. The horizontal displacement mechanism is located on the upper right side of the formation conveyor. The upper left side of the formation conveyor is equipped with a turning and transferring mechanism. The OCV detection mechanism is located below and in front of the turning and transferring mechanism. The unloading mechanism is located in front of the OCV detection mechanism, and the OCV detection mechanism extends into the unloading mechanism.

[0008] Working principle of the invention:

[0009] Feeding and preparation: Place the tray containing several battery cells on the feeding mechanism, and then place them sequentially above the feeding conveyor;

[0010] Transfer and Formation: A leveling and handling assembly moves several battery cells from the feed conveyor and places them on the material conveyor on the left. The material conveyor then sequentially transports the battery cells to the leveling and pressing assembly. Under the precise positioning of the sensor grating, the leveling and pressing assembly flattens and shapes the battery cells to ensure a flat shape and good contact. After being inspected by the leveling and pressing assembly, the processed battery cells are sequentially transported to the material conveyor on the right. Defective battery cells are picked up by the leveling and displacing mechanism and placed on the waste conveyor for discharge. Qualified battery cells are sequentially stacked by the leveling and displacing mechanism and placed on the right input end of the formation conveyor that moves horizontally to the formation mechanism.

[0011] The battery enters the formation area: The formation conveyor transports the cells to be formed to the formation storage assembly at the right input end. The formation storage assembly places them in layers. The formation transfer assembly accurately places the batteries into two formation pressing assemblies for alternating formation pressing and discharge. The right formation pressing assembly performs hot pressing, charging formation, and cold pressing in sequence. After formation pressing, the cells are placed into the formation storage assembly at the left input end by the formation transfer assembly. The formation storage assembly removes them from the formation transfer assembly and places them on the formation conveyor. The formation conveyor transports them to the far left.

[0012] Transfer and Testing: After formation, the batteries are picked up from the formation conveyor by a flipping and transferring mechanism. This mechanism flips the cells 90 degrees so that the electrodes are facing upwards, and then places them on the OCV testing mechanism. The OCV testing mechanism cleans the cells and then tests key electrical properties such as open-circuit voltage to make a preliminary judgment on the battery's charging status and quality.

[0013] Sorting and unloading: The OCV testing mechanism outputs unqualified battery cells, while qualified battery cells are conveyed into the unloading mechanism, which then loads the battery cells into the placement box.

[0014] The feeding mechanism includes a feeding machine box. A lifting push rod plate and a feeding rack are provided on one side of the upper end of the feeding machine box. The lifting push rod plate is located below the feeding rack. The feeding conveyor extends into the feeding rack of the feeding mechanism. Two symmetrically arranged positioning electric push rods are provided on both sides of the lifting push rod plate. An adjusting electric screw is provided on the feeding rack. A vertically arranged material-holding electric push rod is fixed on the moving seat of the adjusting electric screw. A material-holding electric gripper is fixed to the telescopic end of the material-holding electric push rod. The unloading mechanism has the same structure as the feeding mechanism. Several stacked feeding trays containing battery cells are placed on the lifting push rod plate of the feeding mechanism. Several stacked feeding boxes are placed on the lifting push rod plate of the unloading mechanism.

[0015] Using the above structure, the feeding mechanism works as follows: Stacked full trays are lifted to the picking height and positioned. A robotic arm moves horizontally, descends vertically, picks up individual battery cells, and then transfers and releases them to the feeding conveyor line. Once the top tray is empty, it is removed, and the mechanism automatically lifts the next tray to continue operation, achieving continuous automatic supply of battery cells. The unloading mechanism works as follows: Stacked empty boxes are lifted to the loading height. A robotic arm picks up qualified individual battery cells, moves them horizontally, and places them vertically into the boxes, repeating this cycle until the boxes are full. After a full box is removed, the mechanism automatically lifts the next empty box to the loading position, achieving continuous automatic packing and unloading of qualified products.

[0016] The leveling and handling assembly includes a handling base frame, which is fixed on the upper left side of the leveling machine box. Two handling conveyor belts are provided on the handling base frame, and a handling motor is fixed on the handling base frame. The output shaft of the handling motor is fixedly connected to the rotating shaft of the two handling conveyor belts. A handling crossbeam is fixed on the two handling conveyor belts, and a vertically arranged handling electric push rod is fixed on the handling crossbeam. Several equally spaced handling electric grippers are fixed to the telescopic end of the handling electric push rod.

[0017] Using the above structure, the battery cells to be transported are already arranged on the feeding conveyor. The transport motor drives two transport conveyor belts, causing the transport beams fixed on the belts to move horizontally, positioning the entire gripping mechanism at the material-grabbing position above the feeding conveyor. After positioning, the transport electric push rod extends vertically downwards, causing a row of evenly spaced transport electric grippers mounted on its telescopic end to descend until each gripper aligns with a battery cell. After successful gripping, the transport electric push rod retracts, raising the entire row of battery cells to a safe height. The transport motor then drives the transport conveyor belts again, causing the transport beams to move horizontally with the gripped row of battery cells, transferring them from above the feeding conveyor to above the left-side material conveyor. Upon reaching the target position, the transport electric push rod descends again, smoothly placing the entire row of battery cells onto the conveyor surface of the material conveyor. The transport electric grippers simultaneously release the battery cells.

[0018] The leveling and pressing assembly includes a load-bearing conveyor and a leveling and pressing frame. The load-bearing conveyor and the leveling and pressing frame are fixed to the upper center of the leveling machine box. The load-bearing conveyor is located directly below the leveling and pressing frame. A detection laser sensor is installed above the right discharge end of the load-bearing conveyor. The leveling and pressing frame is equipped with several equidistant pressure gauges, several equidistant vertically arranged leveling and pressing hydraulic cylinders, several equidistant limit frames, and several sets of equidistant vertically sliding linkage shafts. The number and position of the leveling and pressing hydraulic cylinders, limit frames, and each set of linkage shafts correspond. Each set of linkage shafts has two shafts. The pressure gauges are electrically connected to the corresponding leveling and pressing hydraulic cylinders. Each cylinder's telescopic end is fixed with a transmission plate. The lower end of each transmission plate is equipped with four sleeve rods. The same lower pressure plate is slidably mounted on the four sleeve rods. The lower end of each sleeve rod is fixed with the same pressing plate. The lower pressure plate is located above the pressing plate. The two linkage shafts of each group are located on both sides of the corresponding flat pressing hydraulic cylinder. The lower end of each group's two linkage shafts is fixed with the same connecting plate. The four sleeve rods pass through the connecting plate. The connecting plate is located between the pressing plate and the lower pressure plate. Each sleeve rod is equipped with a flat spring. The upper and lower ends of the flat spring abut against the lower end of the corresponding connecting plate and the upper end of the lower pressure plate, respectively. Each linkage shaft on the same side as the limit frame is equipped with a limit rod. The limit rod is slidably mounted on the limit frame at the corresponding position.

[0019] Using the above structure, the battery cells conveyed by the left-side material conveyor enter the load-bearing conveyor. When the battery cell is conveyed to directly below the pressing station, the telescopic end of the leveling and pressing hydraulic cylinder pushes the transmission plate downward, thereby driving the four sleeve rods connected to the transmission plate to descend synchronously. The sleeve rods drive the bottom pressing plate down together, pressing against the battery cell located on the load-bearing conveyor. Each leveling and pressing hydraulic cylinder is connected to a pressure gauge to monitor the pressing pressure in real time and feed the data back to the control system, forming a pressure closed loop. On the sleeve rod, a leveling spring is installed between the pressing plate and the lower pressing plate, with the upper and lower ends of the spring abutting against the connecting plate and the lower pressing plate, respectively. When the pressing plate contacts the battery cell and continues to press down, the pressure is transmitted through the pressing plate. At this time, the spring is compressed, forming an elastic buffer. This design can: absorb minor height differences and automatically adapt to minor unevenness of the battery cell thickness or the surface of the load-bearing conveyor; provide overload protection, if the pressure increases abnormally, the spring compression changes, and protection can be triggered in conjunction with the pressure sensor. Limiting: The limit rod on the linkage shaft slides in the corresponding limit frame, providing a mechanical hard limit for the entire pressing stroke to prevent overtravel. Pressing and Holding: Maintaining the pressing state within the set pressure and time completes the shaping process. Resetting: After pressing, the hydraulic cylinder retracts, driving the pressing plate, connecting plate, etc., to rise as a whole via the sleeve rod, completely detaching from the battery cell. The flattening spring then resets. The load-bearing conveyor restarts, conveying the pressed and shaped battery cell to the right. The pressed and shaped battery cell is detected by a detection laser sensor and then conveyed to the right-side material conveyor.

[0020] The transverse pushing assembly includes a transverse mounting base, which is fixed to the upper center of the flattening machine housing. Horizontally arranged transverse electric push rods are fixed on both sides of the upper end of the transverse mounting base. The telescopic ends of the two transverse electric push rods are fixed with the same positioning insulating plate. A vertically arranged push frame electric push rod is slidably arranged in the upper center of the transverse mounting base. A horizontally arranged longitudinal electric push rod is fixed in the upper center of the transverse mounting base. The telescopic end of the longitudinal electric push rod is fixedly connected to the main body of the push frame electric push rod. A transverse positioning push frame is fixed to the lower end of the push frame electric push rod.

[0021] With the above structure, the electric push rod of the pusher is in the retracted state, and the transverse positioning pusher at its end is raised, lower than or flush with the conveyor surface, without hindering the normal transport of the battery cells. The positioning insulation plates driven by the two transverse electric push rods are in the open state, leaving a channel for the battery cells. When the battery cells are carried by the load-bearing conveyor, accurately positioned by the induction grating, and reach the center of the flat pressing station, the load-bearing conveyor pauses. To ensure that the battery cell position is absolutely accurate and does not slip during pressing, the two transverse electric push rods move synchronously, pushing the positioning insulation plates from the front and rear sides of the battery cell's travel direction towards the center for positioning. The electric push rod of the pusher extends, pushing the transverse positioning pusher to descend. The transverse positioning pusher separates several battery cells, and the longitudinal electric push rod drives the electric push rod of the pusher and its transverse positioning pusher at its end to move longitudinally along the conveyor, moving the battery cells left and right for positioning on both sides. The transverse electric push rod retracts, and the positioning insulation plates release the battery cells or open the channel. The electric push rod of the pusher retracts, raising the transverse positioning pusher to a safe height. The longitudinal electric push rod drives the entire pusher mechanism back to the initial waiting position.

[0022] The horizontal displacement mechanism includes a horizontal displacement frame, which is fixed on the upper right side of the leveling machine box. A horizontal displacement electric screw is provided on the horizontal displacement frame. A vertically arranged horizontal displacement electric push rod is fixed on the movable seat of the horizontal displacement electric screw. A horizontal displacement electric gripper is fixed to the telescopic end of the horizontal displacement electric push rod.

[0023] Using the above structure, the horizontal electric gripper covers the material conveyor, waste conveyor 1, and the input end of the formation conveyor. After unqualified battery cells are sent to the material conveyor, the screw-driven gripper grabs them and transfers them to the waste conveyor 1 for rejection. After qualified battery cells are grabbed by the gripper, the screw-driven mechanism crosses the boundary, moving the cells to the upper right input end of the formation conveyor, where they are lowered, released, and stacked sequentially.

[0024] The chemical formation material handling assembly includes a horizontally positioned electric push rod fixed above the chemical formation machine housing and two material feeding slide rails. The two material feeding slide rails are slidably connected to the same horizontal frame. The horizontal frame is fixedly connected to the telescopic end of the horizontal electric push rod. Three equally spaced vertical frames are slidably positioned at the upper end of the horizontal frame. Three equally spaced horizontally positioned electric push rods are fixedly positioned at the upper end of the horizontal frame. The telescopic ends of the vertical electric push rods are fixedly connected to the corresponding vertical frames. Vertical electric push rods are fixedly positioned at the rear side of each vertical frame. Lifting and conveying plates are slidably positioned at the rear side of each vertical frame. The telescopic ends of the vertical electric push rods are fixedly connected to the corresponding lifting and conveying plates. Several sets of symmetrically arranged vertical rods are fixedly positioned on the rear side of each lifting and conveying plate. Several horizontal rods are perpendicularly positioned at the rear end of each vertical rod. Two symmetrically arranged suction cups are provided on each horizontal rod.

[0025] Using the above structure, during the material handling stage, the horizontal electric push rod moves to above the right-side storage assembly, the vertical push rod extends, and the vertical push rod drives the clamp to align with the battery cell. The suction cup grabs the battery cell and rises, while the vertical push rod retracts to complete the material handling. During the handling and alternating operation stage, the horizontal push rod moves the battery cell above the target pressing assembly. With the help of three independent vertical frames, multiple battery cells can be handled in parallel for efficiency, or finished product removal and new product placement can be completed alternately. During the unloading and resetting stage, the vertical push rod extends to feed the battery cell, and the vertical push rod descends to place the battery cell in the pressing clamp. The clamp releases and resets the battery cell. Finished battery cells flow in reverse, stored in the left-side storage assembly or returned to the conveyor. This continuous cycle, with the main control system coordinating the movements of the three frames to match the pressing and forming process cycle, forms a highly efficient and automated logistics loop.

[0026] The formation storage assembly includes a storage box frame. The storage box frames of the two formation storage assemblies are respectively fixed to the upper ends of both sides of the frame of the formation conveyor. Inside the storage box frame, there are four claw mounting plates set at the four corners. Two double-position motor clamping claws are fixed to the inner side of each claw mounting plate. The double-position motor clamping claws at the left and right positions face each other. Lifting plates are slidably provided in the middle of the left and right inner walls of the storage box frame. Vertical electric push rods are fixed in the middle of the left and right inner walls of the storage box frame. The telescopic ends of the vertical electric push rods are fixedly connected to the lifting plates on the same side. Multiple-position motor clamping claws are fixed on both sides of the lifting plates. The lower end of the storage box frame is open.

[0027] Using the above structure, the four corner dual-position motor clamping claws are arranged in pairs to form a rectangular area for horizontal clamping of the battery cells, preventing buffer swaying. Left and right vertical push rods drive the lifting plate, with multiple claws on both sides responsible for vertical support and layered positioning of the battery cells. The battery cells to be formed are conveyed by the conveyor to the open area below the right-side storage component. The vertical push rod adjusts the lifting plate to the receiving height to receive the battery cells from the material handling component. After the claws clamp and fix, the lifting plate rises by one battery cell thickness, cyclically achieving multi-layer stacking buffering. During material removal, the material handling component moves above the storage component and extends below the target battery cell layer. The corresponding claws release, and the suction cups adsorb and remove the battery cell. The left-side storage component is mirror-symmetrical to the right-side component but has the opposite function. The buffered, formed battery cells, after being received and unstacked by the claws, are conveyed to the next process.

[0028] The formation pressing assembly includes a formation pressing frame, which is fixed at the upper middle part of the formation conveyor. A formation heating plate is fixed at the inner bottom of the formation pressing frame. Two sets of symmetrically arranged formation sliding shafts are fixed between the formation heating plate and the inner top of the formation pressing frame. Several formation springs are sleeved on each of the formation sliding shafts. Several formation heating plates are slidably arranged on the two sets of formation sliding shafts. The formation springs are located at the lower end of the corresponding formation heating plates. A formation pressing hydraulic cylinder is fixed at the upper end of the formation pressing frame. The telescopic end of the formation pressing hydraulic cylinder extends into the interior of the formation pressing frame and is fixedly connected to the upper end of the uppermost formation heating plate. Contact charging probes are provided on both the formation heating plate and the formation heating plate.

[0029] Using the above structure, the formation material handling assembly precisely places the battery cell onto the formation heating substrate and the formation heating plate, aligning the cell electrodes with the charging probe to prepare for electrical connection. The formation pressing hydraulic cylinder pushes the formation heating plate downwards, using compression springs to evenly distribute pressure, adapting to differences in cell thickness and ensuring consistent force. During the hot pressing stage, the heating element is activated to raise the temperature and simultaneously complete compaction; during the charging formation stage, the probe is energized to activate the cell according to the program, forming the SEI film. During the cold pressing stage, heating stops, maintaining pressure for shaping and preventing deformation. After the process is completed, the hydraulic cylinder retracts, the spring rebounds, causing the plate to reset and release the material, and the material handling assembly removes the battery cell for transfer to the next stage.

[0030] The material transfer mechanism includes a mounting beam, which is fixed to the side of the storage box frame on the left. A horizontally arranged electric tilting screw is fixed to the end of the mounting beam. A vertically arranged electric tilting push rod is fixed to the movable seat of the electric tilting screw. A tilting motor is fixed to the telescopic end of the electric tilting push rod. A tilting electric gripper is fixed to the output shaft of the tilting motor. The electric tilting gripper is located on the upper left side of the chemical forming conveyor.

[0031] Using the above structure, the mounting beam is fixed to the side of the left storage box frame, with its range of motion covering the left side of the conveyor and above the OCV detection mechanism. The flipping gripper opens and rises to a safe height, with the motor shaft at an initial electrode-level angle to avoid interference with the battery cell. The finished battery cell is conveyed to the left gripping station and stops. The electric screw drives the gripper to move directly above the battery cell, and after the push rod descends, the gripper closes to grip the horizontal battery cell. The push rod lifts the battery cell away from the conveyor, and the flipping motor rotates 90 degrees, turning it into an upright detection posture with the electrodes facing upwards. The screw moves the battery cell above the OCV feeding station, the push rod descends to release the material, and the gripper releases to complete the operation. During the hot pressing stage, the heating element is activated to raise the temperature and simultaneously complete the compaction. During the charging and formation stage, the probe is energized to activate the battery cell according to the program, forming the SEI film. During the cold pressing stage, heating stops, and pressure is maintained to prevent deformation. After the process is completed, the hydraulic cylinder retracts, the spring rebounds, and the pressure plate resets to release the material. The material handling assembly removes the battery cell and transfers it to the next stage.

[0032] The OCV testing mechanism includes a testing housing. From back to front, the testing housing is equipped with a standing conveyor (first type), a cleaning conveyor, a positioning clamping seat, a waste conveyor (second type), and another standing conveyor (third type). Standing conveyor (first type) and standing conveyor (second type) have the same conveying direction. The cleaning conveyor and waste conveyor (second type) have the same conveying direction but are perpendicular to the conveying direction of standing conveyor (first type). Positioning clamping seats are fixed to the tracks of the cleaning conveyor. Each positioning clamping seat has four circumferentially clamping electric push rods arranged in a cross shape. The upper part of the testing housing also includes a longitudinal electric lead screw, a testing seat, and a plasma cleaning head. The detection seat is located on the side of the positioning clamping seat on the detection machine housing. The detection longitudinal electric lead screw is located above the detection seat. The plasma cleaning head is located directly above the cleaning conveyor. A detection moving plate is fixed on the transmission seat of the detection longitudinal electric lead screw. Several equally spaced detection electric push rods are fixed on the detection moving plate. Detection electric grippers are fixed to the telescopic ends of the detection electric push rods. A detection transverse electric lead screw is fixed at the upper end of the detection seat. A vertically arranged detection electric push rod is fixed on the moving seat of the detection transverse electric lead screw. Two OCV test heads are fixed to the telescopic ends of the detection electric push rods.

[0033] Using the above structure, the battery cell with its electrodes facing upwards is delivered to the end via a standing conveyor. A longitudinal screw drives the gripper to grasp the battery cell and transfer it to the positioning clamping seat of the cleaning conveyor. A four-way push rod clamps the battery cell to fix its position. The battery cell is then conveyed to a plasma cleaning head, where non-contact cleaning removes contaminants from the electrode surface, providing accurate conditions for OCV testing. After cleaning, the gripper transfers the battery cell to the positioning seat of the testing chassis. A transverse screw positions the OCV test head, which descends to contact the battery cell electrodes, detecting parameters such as open-circuit voltage. The data is uploaded to the main control system to determine the battery cell's pass / fail status. Passing cells are transferred by the gripper to a second standing conveyor for feeding; failing cells are sent to a second waste conveyor for centralized recycling.

[0034] Compared with existing technologies, this intelligent production logistics system for the formation and capacity testing of new energy lithium batteries has the following advantages: This system integrates multiple processes such as feeding, leveling, formation, testing, and unloading, achieving fully automated flow from raw materials to finished products. It significantly reduces manual intervention, improves production efficiency and consistency, and lowers labor costs and human error rates. Both leveling and formation processes employ closed-loop pressure control and real-time monitoring to ensure the accuracy and consistency of physical shaping and electrochemical reactions. Integrated plasma cleaning and high-precision OCV testing ensure battery quality and reliability from physical contact to electrical performance. Through the coordination of leveling and material handling, formation storage components, and a multi-gripper material handling system, intelligent buffering, scheduling, and efficient transfer of materials between processes are achieved. The alternating operation design of dual formation stations reduces equipment waiting time and improves overall equipment utilization and capacity. Each major actuator adopts a modular, multi-axis drive design, possessing good adaptability and adjustability. The mechanical structure emphasizes buffering and precision guidance, improving equipment operational stability and lifespan while ensuring high precision and high cycle time.

[0052] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0053] like Figures 1-16 As shown, this intelligent production logistics system for the formation and capacity testing of new energy lithium batteries includes a feeding mechanism 1, a leveling mechanism 2, a formation mechanism 4, an OCV detection mechanism 6, and a discharging mechanism 7. The feeding mechanism 1 is located to the left of the leveling mechanism 2, and the formation mechanism 4 is located in front of the leveling mechanism 2. The leveling mechanism 2 includes a leveling housing 14, with an upper cover on top of the leveling housing 14. A main control unit 21 is located on the upper cover. A material conveyor 15, a feeding conveyor 16, and a leveling and handling assembly 17 are located on the upper left side of the leveling housing 14. The material conveyor 15 and the feeding conveyor 16 are located inside the leveling and handling assembly 17. A leveling and pressing assembly 18, a transverse pushing assembly 22, and two sensor gratings 19 are located in the upper middle part of the leveling housing 14. The transverse pushing assembly 22 is located below the leveling and pressing assembly 18, and the two sensor gratings 19 are located on the front and rear sides of the leveling and pressing assembly 18, respectively. The leveling housing 14... The upper right side of the forming mechanism 4 is provided with a material conveyor 15 and a waste conveyor 20. The upper right side of the leveling box 14 is provided with a horizontal displacement mechanism 3, which is located above the material conveyor 15 and the waste conveyor 20. The forming mechanism 4 includes a forming box 49, a forming conveyor 51 located behind the forming box 49, and a forming material handling assembly 50 located above the forming box 49. Above the forming conveyor 51 are two forming storage assemblies 52 and two forming pressing assemblies 53. The two forming storage assemblies 52 are located on the left and right sides of the two forming pressing assemblies 53. The horizontal displacement mechanism 3 is located on the upper right side of the forming conveyor 51. The upper left side of the forming conveyor 51 is provided with a turning and transferring mechanism 5. The OCV detection mechanism 6 is located below the front of the turning and transferring mechanism 5. The unloading mechanism 7 is located in front of the OCV detection mechanism 6, and the OCV detection mechanism 6 extends into the interior of the unloading mechanism 7.

[0054] Feeding and preparation: Place the placement tray 95 containing several battery cells on the feeding mechanism 1, and then place it on top of the feeding conveyor 16 in sequence.

[0055] Transfer and Formation: The leveling and handling assembly 17 transports several battery cells from the feeding conveyor 16 and places them on the material conveyor 15 on the left. The material conveyor 15 then transports the battery cells to the leveling and pressing assembly 18 in sequence. The horizontal pushing assembly 22 performs flat pressing and shaping on the battery cells under the accurate positioning of the induction grating 19. This ensures that the battery cells are flat and have good contact. After being inspected by the leveling and pressing assembly 18, the processed battery cells are transported to the material conveyor 15 on the right in sequence. The unqualified battery cells are picked up by the leveling and displacing mechanism 3 and placed on the waste conveyor 20 for discharge. The qualified battery cells are stacked by the leveling and displacing mechanism 3 in sequence on the right input end of the formation conveyor 51, which moves horizontally to the formation mechanism 4.

[0056] The battery enters the formation area: The formation conveyor 51 transports the battery cell to be formed to the formation storage component 52 at the right input end. The formation storage component 52 places the cells in layers. The formation transfer component 50 accurately places the battery into two formation pressing components 53 for alternating formation pressing and discharge. The right formation pressing component 53 sequentially performs hot pressing, charging formation, and cold pressing. After formation pressing, the battery cell is placed by the formation transfer component 50 into the formation storage component 52 at the left input end. The formation storage component 52 removes the battery cell from the formation transfer component 50 and places it on the formation conveyor 51. The formation conveyor 51 transports the battery cell to the far left.

[0057] Transfer and Inspection: After formation, the battery is picked up from the formation conveyor 51 by the flipping and transferring mechanism 5. The mechanism flips the cell 90 degrees so that the electrodes of the cell are facing upwards and places it on the OCV inspection mechanism 6. The OCV inspection mechanism cleans the cell and then performs tests on key electrical properties such as open circuit voltage to make a preliminary judgment on the charging status and quality of the battery.

[0058] Sorting and unloading: The OCV testing mechanism 6 outputs the unqualified battery cells and the qualified battery cells are transported into the unloading mechanism 7. The unloading mechanism 7 loads the battery cells into the placement box 96.

[0059] Coordination between various departments is uniformly controlled and directed by the main control unit 21 to ensure smooth logistics and accurate processes.

[0060] The feeding mechanism 1 includes a feeding machine box 8. A lifting push rod plate 9 and a feeding rack are provided on one side of the upper end of the feeding machine box 8. The lifting push rod plate 9 is located below the feeding rack. The feeding conveyor 16 extends into the inner side of the feeding rack of the feeding mechanism 1. Two symmetrically arranged positioning electric push rods 10 are provided on both sides of the lifting push rod plate 9. An adjusting electric screw 11 is provided on the feeding rack. A vertically arranged material-holding electric push rod 12 is fixed on the moving seat of the adjusting electric screw 11. A material-holding electric gripper 13 is fixed to the telescopic end of the material-holding electric push rod 12. The unloading mechanism 7 has the same structure as the feeding mechanism 1. Several stacked feeding trays 95 containing battery cells are placed on the lifting push rod plate 9 of the feeding mechanism 1. Several stacked feeding boxes 96 are placed on the lifting push rod plate 9 of the unloading mechanism 7.

[0061] The feeding mechanism 1 operates as follows: Multiple trays 95, already filled with battery cells, are stacked manually or by external equipment onto the lifting pusher tray 9. The input end of the feeding conveyor 16 extends into the inside of the storage rack, awaiting the receipt of the trays. The lifting pusher tray 9 is activated, raising the entire stack of trays to the preset picking height for the top tray. Positioning electric pushers 10 on both sides extend synchronously, clamping or supporting the stack of trays from the sides to prevent displacement or shaking during picking. The adjusting electric screw 11 drives its moving seat to move horizontally, adjusting the placing electric gripper 13 to align with the top tray. The filling electric pusher 12 extends downwards, lowering the placing electric gripper 13 to the picking position. The placing electric gripper 13 closes, firmly grasping the battery cells in the top tray 95. After grasping, the filling electric pusher 12 retracts, lifting the battery cells. The adjusting electric lead screw 11 moves again, accurately transporting the battery cell above the feeding conveyor 16. The loading electric push rod 12 descends, smoothly placing the battery cell onto the feeding conveyor 16. The placing electric gripper 13 releases, returning to its initial position, ready to grab the next battery cell. Once all the battery cells in the top layer placement tray 95 have been removed, the top layer placement tray 95 is removed manually or by external equipment. The lifting push rod plate 9 rises again by the thickness of one placement tray 95, sending the next layer placement tray 95 to the picking height. This process is repeated to achieve continuous automatic feeding.

[0062] The workflow of the unloading mechanism 7: Multiple empty placement boxes 96 are stacked on the lifting pusher plate 9 manually or by external equipment. The output end of the OCV detection mechanism 6 extends into the unloading mechanism 7, and qualified battery cells are conveyed one by one. The lifting pusher plate 9 lifts the empty placement boxes, the positioning electric pusher 10 positions them, and the feeding electric gripper 13, driven by the screw and pusher, grabs the battery cells and places them into the top empty placement box 96. Once full, they are transferred manually or by external equipment to the discharge conveyor line or AGV trolley and sent out of the system. The lifting pusher plate 9 of the unloading mechanism 7 repeats the lifting action to replenish the next empty placement box 96 to the loading station, achieving continuous unloading.

[0063] The leveling and handling assembly 17 includes a handling base frame 23, which is fixed on the upper left side of the leveling machine box 14. Two handling conveyor belts 25 are provided on the handling base frame 23. A handling motor 24 is fixed on the handling base frame 23. The output shaft of the handling motor 24 is fixedly connected to the rotating shaft of the two handling conveyor belts 25. A handling crossbeam 26 is fixed on the two handling conveyor belts 25. A vertically arranged handling electric push rod 27 is fixed on the handling crossbeam 26. Several equally spaced handling electric grippers 28 are fixed to the telescopic end of the handling electric push rod 27.

[0064] The transport motor 24 drives two transport conveyor tracks 25, causing the transport beam 26 fixed on the tracks to move horizontally, positioning the entire gripping mechanism above the feeding conveyor 16 to pick up the material. After positioning, the transport electric push rod 27 extends vertically downward, driving a row of evenly spaced transport electric grippers 28 mounted on its telescopic end to descend until each gripper aligns with a battery cell. After successful gripping, the transport electric push rod 27 retracts, raising the entire row of battery cells to a safe height. The transport motor 24 then drives the transport conveyor tracks 25 again, causing the transport beam 26 to move horizontally with the gripped row of battery cells, transferring them from above the feeding conveyor 16 to above the left-side material conveyor 15. Upon reaching the target position, the transport electric push rod 27 descends again, smoothly placing the entire row of battery cells onto the conveying surface of the material conveyor 15. All transport electric grippers 28 simultaneously release, releasing the battery cells.

[0065] The leveling and pressing assembly 18 includes a load-bearing conveyor 29 and a leveling and pressing frame 35. The load-bearing conveyor 29 and the leveling and pressing frame 35 are fixed to the upper center of the leveling machine housing 14. The load-bearing conveyor 29 is located directly below the leveling and pressing frame 35. A detection laser sensor 30 is installed above the right discharge end of the load-bearing conveyor 29. The leveling and pressing frame 35 is equipped with several equidistant pressure gauges 38, several equidistant vertically arranged leveling and pressing hydraulic cylinders 36, several equidistant limit frames 37, and several sets of equidistant vertically sliding linkage shafts. The number and position of the leveling and pressing hydraulic cylinders 36, limit frames 37, and each set of linkage shafts correspond. There are two linkage shafts in each set. The pressure gauges 38 are electrically connected to the corresponding leveling and pressing hydraulic cylinders 36. Each telescopic end of cylinder 36 is fixed with a transmission plate 34. The lower end of each transmission plate 34 is provided with four sleeve rods. The same lower pressure plate 33 is slidably sleeved on the four sleeve rods. The lower end of each of the four sleeve rods is fixed with the same pressing plate 31. The lower pressure plate 33 is located above the pressing plate 31. The two linkage shafts of each group are located on both sides of the flat pressing hydraulic cylinder 36 at the corresponding position. The lower end of each of the two linkage shafts is fixed with the same connecting plate 32. The four sleeve rods pass through the connecting plate 32. The connecting plate 32 is located between the pressing plate 31 and the lower pressure plate 33. Each sleeve rod is provided with a flat spring. The upper and lower ends of the flat spring abut against the lower end of the connecting plate 32 and the upper end of the lower pressure plate 33 at the corresponding position, respectively. Each linkage shaft on the same side as the limit frame 37 is provided with a limit rod. The limit rod is slidably set on the limit frame 37 at the corresponding position.

[0066] The battery cells conveyed by the left-side material conveyor 15 enter the load-bearing conveyor 29. When the battery cells are conveyed to the area directly below the pressing station, the telescopic end of the flat pressing hydraulic cylinder 36 pushes the transmission plate 34 downward, thereby driving the four sleeve rods connected to the transmission plate 34 to descend synchronously. The sleeve rods drive the bottom pressing plate 31 to descend together, pressing against the battery cells located on the load-bearing conveyor 29. Each flat pressing hydraulic cylinder 36 is connected to a pressure gauge 38 to monitor the pressing pressure in real time and feed the data back to the control system, forming a pressure closed loop. This ensures that the pressure on each batch and each battery cell is accurate and adjustable, meeting the process requirements. On the sleeve rods, a flat spring is provided between the pressing plate 31 and the lower pressing plate 33, with the upper and lower ends of the spring abutting against the connecting plate 32 and the lower pressing plate 33, respectively. When the pressing plate 31 contacts the battery cell and continues to press down, the pressure is transmitted through the pressing plate 31. At this time, the spring is compressed, forming an elastic buffer. This design can: absorb minute height differences and automatically adapt to minor unevenness in cell thickness or the surface of the load-bearing conveyor; provide overload protection, where changes in spring compression due to abnormal pressure can trigger protection in conjunction with a pressure sensor; provide mechanical hard limit by sliding the limit rod on the linkage shaft within the corresponding limit frame 37 to prevent overtravel throughout the entire pressing stroke; maintain the pressing state within the set pressure and time to complete the shaping process; and reset, after pressing, the hydraulic cylinder retracts, driving the pressing plate 31, connecting plate 32, etc., to rise as a whole via the sleeve rod, completely detaching from the cell. The flattening spring then resets. The load-bearing conveyor 29 restarts, conveying the pressed and shaped cell to the right. The laser sensor 30 detects the pressed and shaped cell, checking indicators such as thickness, flatness, and appearance defects, before conveying it to the right-side material conveyor 15.

[0067] The transverse pushing assembly 22 includes a transverse mounting base 39, which is fixed to the upper center of the flattening housing 14. Horizontally arranged transverse electric push rods 40 are fixed on both sides of the upper end of the transverse mounting base 39. The telescopic ends of the two transverse electric push rods 40 are fixed with the same positioning insulating plate 44. A vertically arranged push frame electric push rod 42 is slidably arranged in the upper center of the transverse mounting base 39. A horizontally arranged longitudinal electric push rod 43 is fixed in the upper center of the transverse mounting base 39. The telescopic end of the longitudinal electric push rod 43 is fixedly connected to the main body of the push frame electric push rod 42. A transverse positioning push frame 41 is fixed to the lower end of the push frame electric push rod 42.

[0068] The pusher electric push rod 42 is in the retracted state, and its end, the transverse positioning pusher 41, is raised, lower than or flush with the conveying surface, without obstructing the normal transport of the battery cells. The positioning insulation plate 44 driven by the two transverse electric push rods 40 is in the open state, leaving a passage for the battery cells. When the battery cells are carried by the load-bearing conveyor 29, accurately positioned by the induction grating 19, and reach the center of the flat pressing station, the load-bearing conveyor 29 stops. To ensure that the battery cell position is absolutely accurate and does not slip during pressing, the two transverse electric push rods 40 move synchronously, pushing the positioning insulation plate 44 from the front and rear sides of the battery cell's travel direction toward the center for positioning. The pusher electric push rod 42 extends, pushing the transverse positioning pusher 41 to descend. The transverse positioning pusher 41 separates several battery cells, and the longitudinal electric push rod 43 drives the pusher electric push rod 42 and its end, the transverse positioning pusher 41, to move along the longitudinal direction of the conveyor, causing the battery cells to move left and right, performing left and right side position positioning. The lateral electric push rod 40 retracts, and the positioning insulation plate 44 releases the battery cell or opens the channel. The pusher electric push rod 42 retracts, raising the lateral positioning pusher 41 to a safe height. The longitudinal electric push rod 43 drives the entire pusher mechanism back to the initial waiting position.

[0069] The horizontal displacement mechanism 3 includes a horizontal displacement rack 45, which is fixed on the upper right side of the leveling machine box 14. The horizontal displacement rack 45 is provided with a horizontal electric lead screw 46. A vertically arranged horizontal electric push rod 48 is fixed on the movable seat of the horizontal electric lead screw 46. A horizontal electric gripper 47 is fixed on the telescopic end of the horizontal electric push rod 48.

[0070] With the above structure, the range of motion of the horizontal electric gripper 47 covers the right-side material conveyor 15, the waste conveyor 20, and the right-side input end of the front formation conveyor 51. After leveling, pressing, and inspection are completed, the defective battery cells are conveyed to the right-side material conveyor 15. The horizontal electric screw 46 drives the moving seat to move horizontally, positioning the entire gripping mechanism directly above the defective battery cell. The horizontal electric push rod 48 extends downward, causing the horizontal electric gripper 47 to descend to the gripping height. The horizontal electric gripper 47 closes, firmly gripping the defective battery cell. The horizontal electric push rod 48 retracts, lifting the battery cell. Then, the horizontal electric screw 46 moves again, moving horizontally above the waste conveyor 20. The horizontal electric push rod 48 descends, the horizontal electric gripper 47 releases, and the defective battery cell is accurately placed on the waste conveyor line, completing the rejection of defective products. For the qualified battery cells, the horizontal displacement mechanism performs another set of transfer actions. Similarly, the mechanism first locates and grasps qualified battery cells. Then, the horizontal electric screw 46 drives the grasping mechanism to move horizontally a longer distance, crossing the mechanism boundary, and transporting the battery cells to the upper right input end of the formation conveyor 51 of the front formation mechanism 4. The horizontal electric push rod 48 descends, the horizontal electric gripper 47 releases, and the qualified battery cells are stacked sequentially on the formation conveyor 51 to prepare materials for the formation process.

[0071] The chemical formation material handling assembly 50 includes a horizontally positioned electric push rod 55 fixed above the chemical formation machine housing 49 and two material feeding slide rails 54. The two material feeding slide rails 54 are slidably connected to the same horizontal frame 56. The horizontal frame 56 is fixedly connected to the telescopic end of the horizontal electric push rod 55. Three equally spaced vertical frames 58 are slidably positioned on the upper end of the horizontal frame 56. Three equally spaced horizontally positioned longitudinal electric push rods 57 are fixed to the upper end of the horizontal frame 56. The telescopic ends of the longitudinal electric push rods 57 are connected to the same horizontal frame 55. The vertical frames 58 at corresponding positions are fixedly connected. Each vertical frame 58 has a vertical electric push rod 59 fixed to its rear side. Each vertical frame 58 has a sliding lifting and transporting plate 60. The telescopic end of the vertical electric push rod 59 is fixedly connected to the lifting and transporting plate 60 at the corresponding position. Each lifting and transporting plate 60 has several sets of symmetrically arranged longitudinal rods 61 fixed to its rear side. Each longitudinal rod 61 has several horizontal rods 62 arranged perpendicularly to it at its rear end. Each horizontal rod 62 has two symmetrically arranged suction cups.

[0072] Material Retrieval Stage: When it is necessary to retrieve a battery cell from the right-side material storage assembly: The horizontal electric push rod 55 actuates, moving the entire assembly laterally to directly above the right-side material storage assembly. The corresponding vertical electric push rod 57 drives the vertical frame 58 to extend forward. The vertical electric push rod 59 drives the lifting transport plate 60 to descend, causing the clamp composed of the vertical rod 61 and the horizontal rod 62 to insert into or align with the battery cells stored in layers in the material storage assembly. The suction cup grabs the battery cell. The vertical electric push rod 59 rises, lifting the battery cell; then the vertical electric push rod 57 retracts, removing the battery cell from the material storage assembly.

[0073] In the handling and alternating operation phase: After grasping the battery cell, the horizontal electric push rod 55 drives the entire assembly carrying the battery cell to move laterally above the target formation and pressing assembly 53. Due to the presence of three independent vertical frames 58, the system can be designed for: parallel operation, simultaneously grasping and handling multiple battery cells, improving single-pass handling efficiency; and automated alternating operation, where one vertical frame removes a completed battery cell from the pressing assembly, while another vertical frame places a new battery cell to be formed into another pressing assembly, achieving a "one-in, one-out" connection between the two pressing assemblies, reducing equipment waiting time and improving formation efficiency.

[0074] Material unloading and resetting stage: After reaching the target pressing assembly, the longitudinal electric push rod 57 extends, delivering the battery cell to the center of the pressing station. The vertical electric push rod 59 descends, accurately placing the battery cell onto the pressing fixture. The fixture releases, the lifting transport plate 60 rises, and the vertical frame 58 retracts, completing the unloading process. For battery cells that have already undergone formation, the reverse process is executed: they are removed from the pressing assembly, moved laterally to the left-side formation storage assembly, placed in the storage compartment for temporary storage, or directly returned to the formation conveyor 51.

[0075] Continuous cycle: The above-mentioned pick-up, transfer and placement actions are programmed and controlled by the main control system. The three vertical frames coordinate their actions in sequence, closely cooperating with the "hot pressing-formation-cold pressing" process cycle of the formation and pressing components to form a continuous and efficient automated logistics cycle.

[0076] The chemical formation storage assembly 52 includes a storage box frame 63. The storage box frames 63 of the two chemical formation storage assemblies 52 are respectively fixed on the upper ends of the two sides of the frame of the chemical formation conveyor 51. The storage box frame 63 has four claw mounting plates 65 set at the four corners. Two double-position motor clamping claws 64 are fixed on the inner side of each claw mounting plate 65. The double-position motor clamping claws 64 in the left and right positions face each other. Lifting plates 68 are slidably provided in the middle of the left and right inner walls of the storage box frame 63. Vertical electric push rods 67 are fixed in the middle of the left and right inner walls of the storage box frame 63. The telescopic end of the vertical electric push rod 67 is fixedly connected to the lifting plate 68 on the same side. Multiple motor clamping claws 66 are fixed on both sides of the lifting plate 68. The lower end of the storage box frame 63 is open.

[0077] The dual-motor clamping jaws 64, located on the four-corner jaw mounting plates 65, are arranged in pairs facing each other, forming a stable rectangular clamping area. This area is used for horizontal positioning and clamping of the battery cell from its four sides, preventing the cell from shaking or tipping over during buffering. Vertical electric push rods 67 in the middle of the left and right inner walls drive the lifting pallet 68 to move vertically. Multi-motor clamping jaws 66 installed on both sides of the lifting pallet are used for vertical support and layered positioning of the battery cell from its bottom or side. The battery cell to be formed is conveyed by the forming conveyor 51 to the opening directly below the right-side forming storage assembly 52. ​​The vertical electric push rods 67 drive the lifting pallet 68 to descend to the preset "receiving height" according to the current buffer layer height. The forming material handling assembly 50 transports the battery cell over, passes it through the opening below, and places it on the lifting pallet 68, or it is directly received by the multi-motor clamping jaws 66. The multi-position motor-driven clamping claws 66 actuate to clamp the battery cells from the bottom or side; simultaneously, the four corner double-position motor-driven clamping claws 64 may also coordinate to clamp the battery cells from all sides, completing the secure buffering of a single layer of battery cells. When the next layer of battery cells needs to be buffered, the vertical electric push rod 67 drives the lifting plate 68 to rise precisely by the thickness of one battery cell, ready to receive and buffer the next battery cell, thus repeating the cycle to achieve three-dimensional stacking and buffering of multiple layers of battery cells. When the formation material handling assembly 50 needs to retrieve material, it moves above the storage assembly, and its vertical rods 61 and horizontal rods 62 extend from the lower opening to reach below the target battery cell layer. At this time, the multi-position motor-driven clamping claws 66 and double-position motor-driven clamping claws 64 holding the battery cells in that layer release. The suction cups of the formation material handling assembly 50 adsorb the battery cells and lift and remove them all. The working principle of the formation storage assembly 52 described on the left is mirror-symmetrical to that on the right, but the function is reversed. It is used to receive the formed cells taken out from the formation pressing assembly 53 by the formation material handling assembly 50 and to temporarily buffer them. Its internal jaws first clamp the cells on the formation material handling assembly 50, and then after the formation material handling assembly 50 leaves, its internal jaws release and are re-stacked onto the formation conveyor 51 for transport to the next process.

[0078] The formation pressing assembly 53 includes a formation pressing frame 69, which is fixed to the upper middle part of the formation conveyor 51. A formation heating plate 70 is fixed to the inner bottom of the formation pressing frame 69. Two sets of symmetrically arranged formation sliding shafts 71 are fixed between the formation heating plate 70 and the inner top of the formation pressing frame 69. Several formation springs are sleeved on each of the formation sliding shafts 71. Several vertically distributed formation heating pressure plates 72 are slidably arranged on the two sets of formation sliding shafts 71. The formation springs are located at the lower end of the corresponding formation heating pressure plates 72. A formation pressing hydraulic cylinder 73 is fixed to the upper end of the formation pressing frame 69. The telescopic end of the formation pressing hydraulic cylinder 73 extends into the interior of the formation pressing frame 69 and is fixedly connected to the upper end of the uppermost formation heating pressure plate 72. Contact charging probes are provided on both the formation heating plate 70 and the formation heating pressure plate 72.

[0079] One or more battery cells are precisely placed onto the upper end of the formation heating substrate 70 and several formation heating plates 72 of the assembly by the formation material handling assembly 50. The electrodes of the battery cells are aligned with the contact charging probes on the substrate to establish preliminary electrical connections. The telescopic end of the formation pressing hydraulic cylinder 73 pushes the uppermost formation heating plate 72 downward. Pressure is transmitted through the uppermost formation heating plate 72, sequentially compressing the formation springs connecting each layer of heating plates. The compression deformation characteristics of the springs allow the pressure to be evenly and flexibly distributed to each layer of battery cells.

[0080] Hot pressing stage: While applying pressure, the heating elements inside the formation heating substrate 70 and the formation heating plate 72 are activated to heat the battery cell sandwiched therein, so that it reaches the optimal formation temperature and completes physical compaction at the same time.

[0081] Charging and formation stage: Under the conditions of maintaining pressure and temperature, the contact charging probe is in close contact with the cell electrode and energized. The cell is charged and activated for the first time according to the set program, forming a stable SEI film.

[0082] Cold pressing stage: After charging is completed, heating stops and the system enters the cooling stage. However, the forming and pressing hydraulic cylinder 73 continues to maintain pressure (or is adjusted to the cold pressing set pressure) to shape the battery cell during the cooling process, preventing it from deforming due to temperature changes and internal stress rebound.

[0083] After the entire process (hot pressing-formation-cold pressing) is completed, the formation pressing hydraulic cylinder 73 retracts, causing the uppermost formation heating substrate 70 to rise. The formation springs between the layers then release their stored elasticity, pushing the formation heating plates 72 of each layer back along the formation sliding shaft 71, thereby releasing the clamping force on the battery cell. The formation material handling assembly 50 can then remove the formed battery cell from between the layers and transfer it to the next stage (left-side formation material storage assembly 52).

[0084] The material transfer mechanism 5 includes a mounting beam 90, which is fixed to the side of the storage box frame 63 on the left side. A horizontally arranged electric tilting screw 91 is fixed to the end of the mounting beam 90. A vertically arranged electric tilting push rod 92 is fixed on the movable seat of the electric tilting screw 91. A tilting motor 93 is fixed to the telescopic end of the electric tilting push rod 92. A tilting electric gripper 94 is fixed to the output shaft of the electric tilting motor 93. The electric tilting gripper 94 is located on the upper left side of the chemical forming conveyor 51.

[0085] The mounting beam 90 is fixed to the side of the storage box frame 63 of the left-side formation storage assembly 52, and its range of motion covers the leftmost side of the formation conveyor 51 and above the OCV detection mechanism 6 in front.

[0086] The flip electric gripper 94 is in the open state and is lifted to a safe height by the flip electric push rod 92. The shaft of the flip motor 93 is usually at the initial angle of "electrode level" to avoid interfering with the cells on the conveyor line below.

[0087] After formation, the battery cell is conveyed by the formation conveyor 51 to the leftmost gripping station and stops. The rotating electric screw 91 actuates first, driving its moving seat to move horizontally, accurately positioning the rotating electric gripper 94 directly above the battery cell. The rotating electric push rod 92 extends downward, causing the rotating electric gripper 94 to descend to the gripping height. The rotating electric gripper 94 closes, firmly gripping the battery cell. The battery cell is now in a horizontal position.

[0088] After being grasped, the flipping electric push rod 92 retracts, vertically lifting the battery cell to a sufficient safe height, completely detaching it from the formation conveyor 51. The flipping motor 93 starts, driving its output shaft to rotate 90 degrees. After the flipping is complete, the battery cell changes from a horizontal state to an upright state with the electrodes facing upwards, which is the correct detection posture required by the OCV detection mechanism 6.

[0089] After the flipping is completed, the flipping electric lead screw 91 drives the entire mechanism to move horizontally again, transporting the gripper holding the flipped battery cell to the feeding station above the OCV inspection mechanism 6. The flipping electric push rod 92 descends, placing the battery cell smoothly and accurately onto the conveyor belt or inspection fixture of the OCV inspection mechanism 6. The flipping electric gripper 94 releases, releasing the battery cell.

[0090] The OCV testing mechanism 6 includes a testing housing 74. From back to front, the testing housing 74 is equipped with a first standing conveyor 75, a cleaning conveyor 84, a positioning clamping seat 81, a second waste conveyor 83, and a second standing conveyor 82. The first standing conveyor 75 and the second standing conveyor 82 have the same conveying direction. The cleaning conveyor 84 and the second waste conveyor 83 have the same conveying direction but are perpendicular to the conveying direction of the first standing conveyor 75. Positioning clamping seats 81 are fixed to the track of the cleaning conveyor 84. Each of the two positioning clamping seats 81 has four circumferentially clamping electric push rods 80 arranged in a cross shape. The upper end of the testing housing 74 also has a longitudinal electric lead screw 79, a testing seat 85, and a plasma cleaning head 8. 9. The detection seat 85 is located on the side of the positioning clamping seat 81 on the detection housing 74. The detection longitudinal electric lead screw 79 is located above the detection seat 85. The plasma cleaning head 89 is located directly above the cleaning conveyor 84. A detection moving plate 78 is fixed on the transmission seat of the detection longitudinal electric lead screw 79. Several equally spaced detection electric push rods 77 are fixed on the detection moving plate 78. Detection electric grippers 76 are fixed to the telescopic ends of the detection electric push rods 77. A detection transverse electric lead screw 86 is fixed to the upper end of the detection seat 85. A vertically arranged detection electric push rod 87 is fixed to the moving seat of the detection transverse electric lead screw 86. Two OCV test heads 88 are fixed to the telescopic ends of the detection electric push rod 87.

[0091] The battery cell, flipped 90 degrees with its electrodes facing upwards by the flipping and transferring mechanism 5, is placed on the standing conveyor 75. The standing conveyor 75 transports the battery cell to the end, where the longitudinal electric screw 79 drives the detection transfer plate 78 on its transmission seat to move, positioning a row of electric detection grippers 76 above the battery cell. The electric detection grippers 76 descend and grab the battery cell, then lift it up, and the longitudinal electric screw 79 then moves it horizontally to the track of the side cleaning conveyor 84, where a positioning clamping seat 81 is fixed. The four circumferential clamping electric push rods 80 on the positioning clamping seat 81, arranged in a cross shape, move synchronously to accurately clamp the battery cell from four directions: front, back, left, and right, completely eliminating any shaking during the testing process and ensuring absolutely accurate testing position.

[0092] The cleaning conveyor 84 moves the positioning clamping seat 81 to below the plasma cleaning head 89. The plasma cleaning head 89 is activated to perform non-contact cleaning on the electrode surface of the accurately positioned battery cell. This step effectively removes trace amounts of organic matter or oxide contaminants from the electrode surface, reducing contact resistance, which is a key prerequisite for obtaining accurate and stable OCV test results. After cleaning, the cleaning conveyor 84 moves the battery cell back to below the detection electric gripper 76, and the circumferential clamping electric push rod 80 is released. The detection longitudinal electric screw 79 drives the detection shift plate 78 on its transmission seat to move, positioning the row of detection electric grippers 76 mounted on it above the battery cell. The detection electric grippers 76 descend and grasp the battery cell, then lift it, and the detection longitudinal electric screw 79 then horizontally moves it to the positioning clamping seat 81 at the upper end of the testing housing 74.

[0093] The transverse electric lead screw 86 drives its moving base, accurately positioning the second electric push rod 87 mounted on the base and the two OCV test heads 88 fixed to the telescopic end of the push rod directly above the cell electrodes. The second electric push rod 87 descends, ensuring close contact between the two OCV test heads 88 and the positive and negative electrodes of the cell. The OCV test heads 88 are connected to high-precision measuring instruments to test key electrical performance parameters of the cell, such as open-circuit voltage (OCV). The data is uploaded to the main control system in real time to determine the cell's charging status, consistency, and quality.

[0094] Post-test sorting and distribution:

[0095] Qualified Product Process: After testing, the OCV test head 88 is raised. The electric gripper 76 picks up the qualified battery cell again and transfers it onto the standing conveyor 82 via the longitudinal electric screw 79. This conveyor transports the qualified battery cell to the unloading mechanism 7.

[0096] Non-conforming product process: If the system determines that a battery cell is non-conforming (e.g., voltage is insufficient, short circuit, etc.), the electric gripper 76 will transfer the battery cell to the waste conveyor 83, which is parallel to the cleaning conveyor. The waste conveyor will then transport the non-conforming battery cell out of the inspection area for centralized recycling or processing.

[0097] Working principle of the invention:

[0098] 1. Feeding and Physical Shaping: Feeding: The fully loaded pallets are automatically lifted and positioned by the feeding mechanism, and the grippers pick up the battery cells one by one, placing them onto the feeding conveyor line. Handling and Positioning: The leveling and handling assembly picks up the battery cells in batches from the feeding line and transfers them to the inlet conveyor line of the leveling and pressing station. Under the coordinated action of the induction grating and the lateral pushing assembly, the battery cells are accurately positioned at the pressing center. Pressing and Shaping: Under closed-loop pressure control, the leveling and pressing assembly performs uniform and flexible mechanical pressing on the battery cells, ensuring their flat shape and consistent thickness. Preliminary inspection is performed by sensors after pressing. Sorting and Transfer: Based on the inspection results, the leveling and transferring mechanism removes unqualified battery cells to the waste line, while simultaneously picking up qualified battery cells and stacking them across stations to place them on the input conveyor line of the next process (formation mechanism).

[0099] 2. Formation Activation and Processing: Buffering and Supply: Battery cells are fed into the formation storage assembly on the right side of the formation mechanism via a conveyor line. This assembly uses liftable clamps and motorized grippers to perform multi-layer, three-dimensional buffering of the battery cells, serving a buffering and scheduling function. Efficient Logistics Handling: The formation material handling assembly (a multi-gripper three-axis robot) retrieves battery cells from the storage assembly and alternately transports them to two formation pressing assemblies, achieving a streamlined "one-in, one-out" operation and improving equipment utilization. Core Formation Process: In the formation pressing assembly, the battery cells undergo an integrated "hot pressing-charging formation-cold pressing" process under pressure, temperature, and electrical conditions, completing the initial charging and SEI film formation. This assembly uses a single hydraulic cylinder drive combined with a spring assembly design to achieve uniform pressing of multiple layers of battery cells. Outgoing Buffering: After formation, the battery cells are removed by the material handling assembly and temporarily stored in the formation storage assembly on the left. They are then orderly returned to the conveyor line for transport to the next process.

[0100] 3. Posture Adjustment and Preparation: The flipping and transferring mechanism picks up the horizontally placed battery cell from the end of the formation conveyor line, accurately flips it 90 degrees during the handling process, so that the battery cell electrodes are facing upwards to meet the subsequent testing requirements, and places it on the inlet conveyor line of the OCV testing mechanism.

[0101] 4. OCV Quality Inspection and Automatic Sorting: During the transfer and positioning process, the battery cells undergo changes in posture and position via a conveyor within the inspection mechanism. Upon reaching the cleaning / testing station, they are accurately positioned and clamped from four directions by dedicated positioning clamps. Electrode Cleaning and Testing: First, a plasma cleaning head performs non-contact cleaning on the accurately positioned battery cell electrodes to ensure good test contact. Then, a multi-axis driven OCV testing head descends, contacts the electrodes, and performs high-precision testing of key electrical properties such as open-circuit voltage. Intelligent Sorting: Based on the test results, the system controls the transport grippers to place the battery cells onto different conveyor lines: qualified products flow to the final unloading mechanism, while unqualified products are rejected and sent to the waste line.

[0102] 5. Finished Product Storage: The unloading mechanism is symmetrical in structure to the loading mechanism but functions in the opposite way. It picks up qualified battery cells one by one or in sequence and neatly packs them into stacked empty packaging boxes. The full boxes are removed from the system, realizing the automatic unloading of finished products.

[0103] In summary, this system integrates multiple processes such as feeding, leveling, chemical formation, inspection, and unloading, achieving fully automated flow from raw materials to finished products. This significantly reduces manual intervention, improves production efficiency and consistency, and lowers labor costs and the rate of human error.

[0104] Both the leveling and formation processes employ closed-loop pressure control and real-time monitoring to ensure the accuracy and consistency of physical shaping and electrochemical reactions. Integrated plasma cleaning and high-precision OCV testing guarantee battery quality and reliability from physical contact to electrical performance.

[0105] Through the coordinated operation of horizontal material transfer, chemical formation storage components, and a multi-gripper material handling system, intelligent buffering, scheduling, and efficient transfer of materials between processes are achieved. The alternating operation design of the dual chemical formation stations reduces equipment waiting time and improves overall equipment utilization and capacity.

[0106] Each major actuator (such as the conveyor, gripper, and press) adopts a modular, multi-axis drive design, possessing excellent adaptability and adjustability. The mechanical structure emphasizes buffering (such as springs) and precision guidance (such as sliding shafts and lead screws), ensuring high precision and high cycle time while improving the equipment's operational stability and lifespan.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
