Description

Technical Field

[0001] This invention relates to the field of battery plate wrapping machine technology, and in particular to a multi-station parallel operation system for automatic battery plate wrapping. Background Technology

[0002] Lead-acid batteries are widely used in automotive starting, energy storage stations, and electric two-wheelers due to their advantages such as stable voltage, low price, high safety, and recyclability. Plate coating is a core process in the production of lead-acid batteries. Its function is to wrap PE separators between the positive and negative plates to prevent short circuits and ensure the permeation space of electrolyte. The processing precision and efficiency of the plate coating process directly affect the final capacity and service life of the battery.

[0003] Early PCB wrapping processes relied primarily on manual labor, resulting in low efficiency, insufficient daily capacity of single production lines, and significant alignment errors in the separators during manual wrapping, which could easily lead to short circuits between the positive and negative electrodes. To improve processing efficiency, some manufacturers have developed multi-station PCB wrapping equipment.

[0004] However, most existing multi-station plate wrapping equipment uses servo motors and reducers for their station rotation drive mechanisms. The large inertia of the rotating station disk results in significant inertial impact during start-up and shutdown, leading to poor positioning accuracy and requiring additional braking mechanisms, which increases equipment costs. Some hydraulically driven equipment also suffers from insufficient torque and low rotation angle control accuracy. Furthermore, most existing multi-station equipment uses a single set of partition plate loading and cutting mechanisms, requiring each station to queue up for processing. This prevents each station from having its own processing mechanism and truly parallel operation, limiting the increase in production capacity. Summary of the Invention

[0005] This invention solves the problems in related technologies by proposing a multi-station parallel operation system for automatic battery plate wrapping, which solves the problems of low efficiency of existing manual operation and inability of mechanical plate wrapping to share multiple stations.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a multi-station parallel operation system for automatic battery plate wrapping, comprising a feeding belt group and a multi-station system base. The multi-station system base is disposed on one side of the discharge end of the feeding belt group. A rotating station disk is mounted on the upper surface of the multi-station system base. The rotating station disk is rotatably connected to the multi-station system base, and a rotary cylinder for driving the rotating station disk is disposed in the multi-station system base. Several sets of wrapping main frames are mounted on the upper surface of the rotating station disk along the circumferential direction. A partition plate feeding assembly is mounted on the wrapping main frame. A plate transfer assembly is mounted below the partition plate feeding assembly. A pressing and cutting assembly that cooperates with the partition plate feeding assembly is also disposed on the wrapping main frame. A flipping assembly is also disposed at the discharge end of the plate transfer assembly.

[0007] By adopting the above technical solution, a rotating worktable is set on the multi-station system base with a rotating connection. The rotating worktable is driven by a rotating cylinder. Compared with the traditional motor drive method, the rotating cylinder can provide greater rotational torque, drive multiple sets of plate wrapping main frames to rotate synchronously, reduce start-stop impact, and improve the positioning accuracy of the stopping position. No additional braking mechanism is required, which reduces the overall cost of the equipment. Multiple independent plate wrapping main frames are set along the circumference of the rotating worktable. Each plate wrapping main frame is independently equipped with a partition plate loading component, an electrode plate transfer component, a pressing and cutting component, and a flipping component. Each station can independently complete the entire process from electrode plate loading to plate wrapping and flipping out. The rotating worktable can complete the output of one finished product in one rotation, truly realizing multi-station parallel operation, greatly reducing process waiting time and improving processing cycle. The flipping component is directly integrated into the output end of each plate wrapping main frame. After the plate wrapping and stacking is completed, the combined electrode plate group can be directly flipped to a vertical state without the need for additional subsequent flipping process. It can be directly connected to the subsequent group assembly automated production line, improving the automation level of the entire production line and reducing additional equipment investment.

[0008] As a preferred embodiment, the feeding belt assembly includes a main frame, an electrode plate conveyor belt, and an electrode plate feeding assembly. The electrode plate conveyor belt is horizontally arranged on the upper surface of the main frame, and the main frame is also equipped with a feeding motor that drives the electrode plate conveyor belt to rotate. The electrode plate feeding assembly includes a multi-axis robotic arm and an electric suction cup. The multi-axis robotic arm is arranged at the output end of the electrode plate conveyor belt and is fixedly connected to the main frame.

[0009] By adopting the above technical solution, the feeding belt assembly is set as a structure of electrode plate conveyor belt plus electrode plate loading assembly. The electrode plate conveyor belt can continuously transport bare electrode plates to be processed in batches, ensuring a continuous supply of raw materials and avoiding the problem of waiting for materials and stopping work when multiple workstations are operating in parallel. A multi-axis robotic arm drives an electric suction cup to grab the electrode plates. The multi-axis robotic arm is flexible and can be adapted to grab and position electrode plates of different sizes. The electric suction cup adsorption and grabbing method will not damage the surface of the electrode plate and has good grabbing stability. Compared with clamping gripping, there will be no problem of electrode plate being crushed or lead falling off, thus improving the material qualification rate.

[0010] As a preferred embodiment, the multi-station system base includes a shock-absorbing base, a system box, and a positioning bracket for rotating the rotating workstation plate. The system box is fixedly installed on the upper surface of the shock-absorbing base, and the front surface of the system box is equipped with several sets of flip-open boxes. A mechanical base plate is also horizontally arranged on one side of the upper surface of the system box. The mechanical base plate is fixedly connected to the system box, and a discharge robot is installed on the mechanical base plate. The positioning bracket is fixedly installed on the upper surface of the system box.

[0011] By adopting the above technical solution, the multi-station system base adopts a structure of shock-absorbing base, system box, and positioning support shell. The shock-absorbing base can effectively buffer the vibration generated by the rotation and start-up of the rotating workstation plate and the pressure cutting operation, improve the structural stability of the entire equipment, reduce positioning errors caused by vibration, and extend the service life of the equipment. The front of the system box is equipped with a flip-open box door, which makes it convenient for operators to maintain and repair the rotating cylinder, hydraulic line, and control line inside the system box, reducing the difficulty of equipment maintenance. A mechanical base plate with a discharge robot is set on one side of the system box, which can directly grab the finished product combination plate group after it has been flipped up, realize the automation of discharge, eliminate the need for manual unloading, and improve the safety of operation.

[0012] As a preferred embodiment, the rotary workstation includes a rotary disk, an inner ring seat, and a positioning seat for mounting the main frame of the packaging plate. The inner ring seat is coaxially mounted on the lower end face of the rotary disk and is integrally formed with the rotary disk. The inner ring seat is mounted in the positioning support shell by bearings. The positioning seat is uniformly fixed on the upper end face of the rotary disk along the circumferential direction, and the positioning seat is also provided with an installation groove.

[0013] By adopting the above technical solution, the rotary workstation tray adopts a structure of rotary tray plus inner ring seat plus positioning seat. The inner ring seat is installed in the positioning bracket through bearing, which makes the rotation of the rotary tray smoother and the coaxiality higher, avoiding wobbling and deflection during the rotation of the rotary tray and ensuring the positional accuracy of each workstation after rotation. The positioning seats with mounting grooves are evenly arranged along the circumference, which facilitates the positioning and installation of the packaging main frame, and also makes it easy to adjust the number of packaging main frames according to production needs, adapting to the production needs of different production capacities. The modular design also makes it easy to disassemble and replace a damaged individual packaging main frame without replacing the entire rotary workstation tray, reducing maintenance costs.

[0014] As a preferred embodiment, the main frame of the packaging plate includes a base frame, a transverse frame, a roller frame, and a hanging frame for installing the pressure cutting assembly.

[0015] By adopting the above technical solution, the main frame of the packaging plate adopts a modular structure of base frame, horizontal frame, roller frame and hanging frame. Each functional part has a clear division of labor and good structural stability. The inclined setting of the roller frame conforms to the routing angle of the partition plate feeding, which can ensure the appropriate tension during the feeding of the roll PE partition plate, avoid wrinkles and loosening during the feeding process, and improve the accuracy of partition plate cutting and pressing. The hanging frame provides a stable installation foundation for the pressing and cutting components, ensuring the stability of the pressing and cutting mechanism during the pressing and cutting operation and reducing the problem of cutting deviation.

[0016] As a preferred embodiment, the lower end face of the transverse frame is provided with a lower support shell for mounting the electrode plate transfer assembly, and the lower support shell is integrally formed with the transverse frame. The upper end of the transverse frame is also provided with a reversing pressure roller, the two ends of which are rotatably connected to the transverse frame. An external roller frame is also fixedly installed on the outer side of the transverse frame.

[0017] By adopting the above technical solution, an integrally formed lower support shell is set at the lower end of the transverse frame, providing a stable installation space for the electrode plate transfer assembly. The integrally formed structure has higher strength, does not require additional assembly, and reduces assembly errors. The setting of the deflecting pressure roller can deflect and tension the rolled PE partition during the conveying process, ensuring that the partition is always in a straight and taut state during the feeding process, avoiding wrinkles and arching of the partition, and improving the cutting dimension accuracy. The external roller frame is set on the outside, providing a stable installation position for the winding roller assembly. The placement of the winding roller assembly on the outside also facilitates the replacement of the used PE material roll residue, making the operation more convenient.

[0018] As a preferred embodiment, the partition loading assembly includes a feeding roll, a roll of PE, and a take-up roll assembly. The feeding roll is installed at the head of the roller frame, and both ends of the feeding roll are rotatably connected to the roller frame. The take-up roll assembly is rotatably installed in an external roller frame, and a take-up motor for driving the take-up roll assembly is fixed on one side of the external roller frame.

[0019] By adopting the above technical solution, the partition feeding assembly adopts a structure of feeding roller plus winding PE plus take-up roller group. The winding PE is continuously fed, which has better feeding continuity than manual single-piece feeding of partitions and is suitable for automated operation. The take-up roller group rotates under the drive of the take-up motor to take up the material, which can accurately control the length of the partition feeding, ensure the dimensional accuracy of each feeding, and avoid the problem of raw material waste or dimensional defects caused by feeding too long or too short. The overall structure is simple and easy to maintain.

[0020] As a preferred embodiment, the electrode plate transfer assembly includes a main conveying roller, a secondary conveying roller, and a conveyor belt. The main conveying roller and the secondary conveying roller are rotatably mounted at both ends of the lower support shell, and a drive motor for driving the main conveying roller to rotate is fixedly mounted on the lower support shell. The two ends of the conveyor belt are respectively sleeved on the main conveying roller and the secondary conveying roller. An electrode plate limiting frame is also fixedly mounted on one side of the lower support shell, and the electrode plate limiting frame is positioned above the feed end of the conveyor belt.

[0021] By adopting the above technical solution, the electrode plate transfer assembly adopts a structure of main conveyor roller, auxiliary conveyor roller and conveyor belt, which has stable transmission and can accurately control the position of electrode plate transfer, ensuring the accuracy of the electrode plate moving to the bottom of the partition and the stacking position; an electrode plate limiting frame is set above the feed end of the conveyor belt, which can position and limit the electrode plate placed on the conveyor belt, avoid the electrode plate being placed skewed and causing subsequent partition pressing misalignment, improve the processing accuracy, and has a simple structure and good limiting effect.

[0022] As a preferred embodiment, the pressure cutting assembly includes a guide vertical shell, a sliding seat, and a cutting pressure blade. The guide vertical shell is vertically fixed to the lower end face of the hanging frame, the sliding seat is slidably installed at the lower end of the guide vertical shell, and a control electric cylinder for driving the sliding seat to rise and fall is also provided in the guide vertical shell. The cutting pressure blade is fixedly installed at the lower end face of the sliding seat.

[0023] By adopting the above technical solution, the pressure cutting assembly adopts a structure of guide vertical shell, sliding seat, and cutting pressure knife. The sliding seat is driven to rise and fall by a control electric cylinder. The lifting control is highly accurate and the pressure is stable, which can ensure that the cutting depth and pressure of the cutting pressure knife are appropriate. This ensures that the PE partition is completely cut off without damaging the electrode plate below. The guide vertical shell guides the movement of the sliding seat to avoid skewing during the cutting process of the cutting pressure knife, ensuring that the cutting edge is neat and the dimensional accuracy meets the requirements.

[0024] As a preferred embodiment, the flipping assembly includes a base bracket, a receiving seat, and a pressing seat plate. The base bracket is located below the material outlet of the conveyor belt. The receiving seat is rotatably mounted on the head of the base bracket, and a bottom electric cylinder is provided on the receiving seat to drive the base bracket to flip. A guide slide is fixed on the upper surface of the receiving seat, and the pressing seat plate is slidably mounted on the guide slide. A top electric cylinder is provided at the head of the guide slide to drive the pressing seat plate to approach or move away from the base bracket.

[0025] By adopting the above technical solution, the flipping assembly adopts a structure of bottom bracket plus receiving seat plus pressure holding plate. The top electric cylinder drives the pressure holding plate to cooperate with the receiving seat to clamp the combined electrode plate group. The clamping force is stable, avoiding the combined electrode plate group from scattering and misaligning during the flipping process. The bottom electric cylinder drives the receiving seat to flip, with high flipping angle accuracy. It can accurately achieve 90-degree flipping, flipping the horizontal combined electrode plate group to a vertical state, directly meeting the feeding requirements of subsequent processes. No manual secondary adjustment is required, which improves the degree of automation.

[0026] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention adopts a multi-station parallel operation structure, with each station independently configured with a complete set of processing mechanisms, truly realizing simultaneous processing at each station. The rotary cylinder drives the rotary worktable to rotate, resulting in minimal start-stop impact and high positioning accuracy, thus improving processing efficiency compared to traditional single-station serial equipment. By modularizing the design of each functional module, the positioning accuracy of each mechanism is high. Through the coordination of multi-axis robotic arms for loading, electrode plate limiting, tensioning partition feeding, and precise pressing and cutting, processing accuracy is high, the alignment error of the partitions in the combined electrode plate group is small, the defect rate is reduced, and raw material waste is significantly reduced, lowering production costs. By directly integrating an automatic flipping and unloading function, after the plate stacking is completed, the combined electrode plate group is directly flipped to a vertical state, allowing direct connection to subsequent automated group assembly production lines. No additional flipping process or equipment is required, reducing production steps, lowering equipment investment for the entire production line, and improving overall production efficiency.

The partition loading assembly 5 adopts a structure of feeding roller 51, wound PE 52, and take-up roller assembly 53. It uses a continuous feeding method of wound PE 52, which has better feeding continuity than manual single-piece feeding of the partition and is suitable for automated operation. The take-up roller assembly 53 rotates under the drive of the take-up motor 431 to take in the material, which can accurately control the length of the partition feeding, ensure the dimensional accuracy of each feeding, and avoid the waste of raw materials or the problem of unqualified size caused by feeding too long or too short. The overall structure is simple and easy to maintain.

It has stable transmission and can accurately control the position of electrode plate transfer, ensuring the accuracy of the electrode plate moving to the bottom of the partition and the stacking position. An electrode plate limiting frame 45 is set above the feed end of the conveyor belt 63, which can position and limit the electrode plate placed on the conveyor belt 63, avoiding the electrode plate being placed skewed and causing subsequent partition pressing misalignment, thus improving the processing accuracy. The structure is simple and the limiting effect is good.

[0052] Reference Figure 7 and Figure 8 The cutting assembly 7 includes a guide vertical shell 71, a sliding seat 72, and a cutting pressure blade 73. The guide vertical shell 71 is vertically fixed to the lower end face of the hanging frame 44.

The control cylinder 70 drives the sliding seat 72 to rise and fall, which has high lifting control accuracy and stable pressure. This ensures that the cutting pressure blade 73 falls to the appropriate cutting depth and pressure, which can ensure that the PE partition is completely cut off without damaging the electrode plate below. The guide vertical shell 71 guides the movement of the sliding seat 72 to avoid the cutting pressure blade 73 from deflecting during the cutting process, ensuring that the cutting edge is neat and the dimensional accuracy meets the requirements.

[0053] Reference Figure 10 , Figure 11 and Figure 12The flipping assembly 8 includes a base bracket 81, a receiving seat 82, and a pressing seat plate 83.

The clamping force is stable, preventing the combined electrode assembly from scattering and misaligning during the flipping process. The bottom electric cylinder 820 drives the receiving seat 82 to flip.

[0054] Working principle:

[0055] This multi-station parallel operation system for automatic battery plate wrapping is coordinated by a PLC controller. The overall working principle is as follows:

[0056] Material preparation stage: The electrode conveyor belt 12 of the feeding belt group 1 continuously conveys the bare electrode plates to be processed in batches. The rotary cylinder 20 drives the rotary workstation disk 3 to rotate, and rotates the empty workstation main frame 4 to the feeding position, waiting for processing.

[0057] One-time loading: The multi-axis robotic arm 131 drives the electric suction cup 132 to move to the output end of the electrode plate conveyor belt 12. After adsorbing and grabbing the bare electrode plate, the electrode plate is accurately placed into the electrode plate limiting frame 45 of the electrode plate transfer component 6 of the main frame 4 of the plate packaging station, which is in the loading station, to complete the electrode plate positioning.

[0058] Partition cutting: The electrode plate transfer assembly 6 is started, conveying the bare electrode plate placed at one time to the lower part of the cutting assembly 7; the winding roller group 53 of the partition plate feeding assembly 5 rotates under the drive of the winding motor 431, pulling the rolled PE52 partition plate on the feeding roller 51 to the position below the cutting assembly 7 and above the corresponding electrode plate, keeping it taut and straight; the control cylinder 70 of the cutting assembly 7 drives the sliding seat 72 to descend along the guide vertical shell 71, and the cutting blade 73 moves downward to cut the rolled PE52 into a partition plate with the same size as the electrode plate, and at the same time presses the cut partition plate onto the upper surface of the bare electrode plate below to complete the partition covering;

[0059] Secondary feeding and stacking: After the pressing is completed, the cutting knife 73 rises and resets, and the electrode plate transfer assembly 6 continues to drive the electrode plate covered with a layer of separator to move towards the discharge end. After it moves into place, the electrode plate feeding assembly 13 grabs another bare electrode plate and places it above the separator to form a combination plate of electrode plate-separator-electrode plate.

[0060] Flipping and unloading: The electrode plate transfer assembly 6 conveys the combined plate downwards, causing it to fall onto the receiving seat 82 of the flipping assembly 8; the top electric cylinder 830 of the flipping assembly 8 drives the pressing seat plate 83 to move downwards along the guide slide 821, which, together with the receiving seat 82, clamps and fixes the combined plate to prevent it from flipping and scattering; then the bottom electric cylinder 820 drives the receiving seat 82 to rotate 90 degrees around the bottom bracket 81, flipping the originally horizontally placed combined plate into a vertical state to meet the feeding requirements of subsequent processes;

[0061] Cyclic operation: After the flipping is completed, the rotating workstation plate 3 is driven by the rotating oil cylinder 20 to rotate one workstation angle, so that the next packaging plate main frame 4 to be processed is rotated to the loading workstation. The above processing process is repeated. The processed vertical state combined plate is picked up by the unloading robot on the mechanical base plate 222 and sent to the next process. All workstations process independently at the same time, realizing multi-workstation parallel uninterrupted operation.

[0062] In this embodiment, the rotary cylinder 20 is an HSG type engineering hydraulic cylinder with a rated working pressure of 16MPa and a maximum output torque of 1200N·m. An angle encoder is used in conjunction with a Siemens S7-1200 series PLC controller (model 6ES7 214-1AG40-0XB0) to achieve closed-loop control of the rotation angle. The rotation angle control accuracy is ±0.1°, meeting the positioning requirements of 60° rotation per station for all six workstations. The control response is fast and the stability is good. The feeding motor is a Y2-80M2-4 type three-phase asynchronous motor with a rated power of 0.75kW and a rated speed of 1440r / min, capable of stably driving the electrode conveyor belt to feed materials at a uniform speed. The multi-axis robotic arm 131 is an ABB IRB 1200 six-axis industrial robotic arm with a load capacity of 7kg and a repeatability of ±0.02mm, meeting the accuracy requirements for electrode gripping and loading. The electro-chuck 132 is a CNHY-1520 type square multi-hole electrostatic chuck, providing uniform suction force without damaging the electrode. The shock-absorbing seat 21 adopts a combination structure of cast iron seat and rubber shock-absorbing pad. The rubber shock-absorbing pad is 20mm thick and has a Shore hardness of 60HA, which can effectively filter the vibration generated during operation and improve the stability of the equipment. The discharge robot is a Huichuan IRB10-700 four-axis robot with a repeatability of ±0.1mm, which meets the requirements for finished product gripping and discharging. The inner ring seat 32 is installed in the positioning support shell 23 through a 30216 type tapered roller bearing, which has strong load-bearing capacity and high rotational accuracy. Both the rotating disk 31 and the positioning seat 33 are made of Q235 carbon steel with a powder-coated anti-rust treatment, resulting in high structural strength. The positioning seat 33 is also provided with a mounting groove 331. The roller frame 43 is tilted and fixed to one side of the upper end face of the transverse frame 42 at an inclination angle of 30°, which meets the requirements of the feeding and routing of the roll-type PE partition. The hanging frame 44 is horizontally fixed to one side of the roller frame 43. All components of the main frame of the plate wrapping are made of aluminum alloy, which is lightweight, has high structural strength, and reduces the rotational inertia of the rotating workstation disk. The reversing pressure roller 42 is covered with a 1mm thick rubber layer to prevent scratching the PE partition. An external roller frame 422 is also fixedly installed on the outer side of the transverse frame 42. The winding motor 431 is a 42HS48-1684 stepper motor with a step angle of 1.8°, high positioning accuracy, and precise control of the winding length to ensure that the dimensional accuracy of each feed meets the requirements. The drive motor is a JGA25-370 DC geared motor with a rated voltage of 24V, a reduction ratio of 1:100, and stable speed, which can drive the conveyor belt to move the electrode plate at a uniform speed. The electrode plate limiting frame 45 is made of food-grade PP material with moderate hardness and will not scratch the edge of the electrode plate. The control cylinder 70 uses the Leadshine Intelligent EC60-L50-500W push rod type electric cylinder with a stroke of 50mm, a maximum thrust of 5000N, and a repeatability of ±0.05mm. It can meet the lifting drive requirements of the cutting pressure knife, and the thrust is sufficient to cut the PE partition. At the same time, the positioning accuracy is high and it will not damage the electrode plate.Both the bottom electric cylinder 820 and the top electric cylinder 830 are Langgao LG60 series electric cylinders with a rated thrust of 1000N, a repeatability of ±0.1mm, high precision in controlling the flipping angle, and stable clamping force. The inner sides of the receiving seat 82 and the pressure seat plate 83 are covered with 3mm thick foamed rubber pads to increase friction and buffer the clamping force, thus preventing damage to the electrode plates.
