Description

Technical Field

[0002] With the continuous development of technology, the human demand for energy is also increasing. As a highly efficient energy storage device that can be repeatedly charged and discharged, lithium batteries have been widely used in new energy vehicles, 3C products, Bluetooth headsets and other fields. As an important component of the battery, the diaphragm plays a role in isolating the electrolyte and protecting the battery. At the same time, the quality of the diaphragm has a crucial impact on the processing and performance of lithium batteries. Once problems such as poor appearance of the diaphragm occur, it will affect the processing accuracy of the battery and the battery performance. Usually, the production scale of the base film is very large, and it is difficult to ensure that the film surface has no deformation, edge collapse and other situations. Therefore, coating one or more layers of powder with a micron thickness level on the outer layer of the base film can not only effectively cover the edge collapse and deformation problems of the original base film; but also can improve the liquid retention capacity, thermal stability and puncture performance of the diaphragm, and finally can reduce battery short circuit, enhance the battery cycle life, prevent battery swelling, etc.; In order to meet the wide-width requirements of customers, at present, each diaphragm manufacturer in the industry needs to use a slitter to slit the products. When slitting, only a single roll of film can be slit by the same machine, and multiple rolls of film cannot be slit simultaneously. Moreover, traditional diaphragm slitters mostly adopt the single master roll slitting mode, and there are the following problems: Low efficiency: Frequent roll changes are required for single-roll slitting, and the equipment idle time accounts for 20% - 30%; Insufficient precision: Tension fluctuations during the slitting process are likely to cause edge burrs (height ≥ 5μm) or wrinkles, affecting battery safety; Material waste: The waste rate of single-roll slitting is ≥ 8%, and the equipment floor space cost is high during multi-roll slitting; Therefore, the technical personnel in this field have provided an efficient diaphragm slitter for synchronous slitting of multiple master rolls and its intelligent control method to solve the problems raised in the above background art.

[0012] An intelligent control method for an efficient diaphragm slitting machine with synchronous slitting of multiple master rolls includes the following steps: S1: The operator inputs the specification parameters of the diaphragm master roll to be slit and the initial working parameters of each component through the human-machine interface, and starts the equipment self-check program to detect each component of the slitting machine; S2: The first servo motor drives the transmission shaft to rotate, drives the upper pressing plate and the lower pressing plate to clamp the master roll through the transmission system, drives the master roll to rotate through the driving shaft, and real-time monitors the conveying state of the master roll through the position sensor. When a deviation occurs, adjusts the driving motor speed of the corresponding driving shaft; S3: The tension sensing shaft real-time collects the diaphragm tension data and transmits it to the control system. The control system compares the collected data with the preset tension range. When the tension is abnormal, controls the driving motor speed of the conveying roller to adjust; S4: The second servo motor drives the rotating shaft to rotate according to the preset slitting speed parameter, drives the circular knife to slit, real-time detects the slitting quality through the vision detection device. When the quality does not meet the standard, adjusts the working parameters of the slitting mechanism, and winds the slit base film onto the winding roller in sequence; S5: The control system monitors the operating status of each component of the slitter in real time through sensors. When abnormal data is detected, it judges the type and location of the fault according to the preset fault diagnosis logic, issues an alarm signal and displays the fault information, and automatically records the fault data at the same time.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The first servo motor is used as the power source. After starting, it outputs power to drive the transmission shaft to rotate. The transmission shaft relies on the bearing seats at both ends to achieve stable support and rotation, ensuring the smoothness of power transmission. A driving wheel is installed at a position close to the bearing seat of the transmission shaft. The driving wheel rotates synchronously with the transmission shaft and transmits power to the transmission wheel through a synchronous belt. The transmission wheel is fixed to one end of the reciprocating screw and is located in the transmission groove opened on the workbench. In this way, a power transmission link from the first servo motor to the reciprocating screw is formed. In this transmission system, the synchronous belt not only realizes the reliable transmission of power, but also uses its synchronous transmission characteristics to ensure The rotation speeds of the driving wheel and the transmission wheel are consistent, thereby ensuring that multiple reciprocating screws rotate synchronously, providing a stable basis for subsequent adjustment actions; when the reciprocating screw rotates under power drive, the adjustment block movably connected thereto will make linear motion along the adjustment slot. Since the adjustment slot is symmetrically arranged between the two sets of limit seats and a reciprocating screw is installed inside, the movement of the adjustment block is guided and constrained by the adjustment slot. By controlling the rotation direction and speed of the first servo motor, the moving distance and speed of the adjustment block can be accurately controlled. The linear motion of the adjustment block is transmitted to the upper pressure plate through the transmission rod and the connecting piece. When the adjustment block When moving, it drives the transmission rod to swing, and then pushes the connecting piece and the upper pressure plate to slide between the limit seats on both sides, forming an upper and lower clamping structure with the lower pressure plate. When clamping the diaphragm mother roll, it can not only ensure the reliable fixation of the mother roll to prevent it from displacement or sliding during the slitting process, but also avoid damage to the diaphragm due to excessive clamping force, thereby ensuring the integrity of the diaphragm and the slitting quality. In the actual working process, the operator can set the operating parameters of the first servo motor through the control system according to the specifications of the mother roll, adjust the upper and lower pressure plates to the appropriate spacing, and accurately limit the diaphragm mother roll for subsequent synchronization. The conveying and slitting processes provide stable and reliable basic conditions; the limit frames on both sides of the workbench are provided with limit grooves, and the limit pieces on both sides of the rotating frame are embedded in the limit grooves to form a guide structure, which limits the radial displacement of the rotating frame and only allows it to slide along the limit groove direction to ensure the position accuracy of the disassembly roller during installation. By swinging the lever, the other end of the lever contacts or connects with the disassembly roller, and the linear motion of the driving member is converted into the loading and unloading action of the disassembly roller by using the lever principle, and the disassembly roller is pressed between the rotating frame and the driving roller to ensure reliable transmission, and the disassembly roller is lifted to separate it from the driving roller, which is convenient for manual rapid placement. The first movable rod under the rotating frame is connected to the guide wheel, which is embedded in the tooth groove of the synchronous belt. When the rotating frame moves axially along the transmission shaft, the guide wheel rolls on the synchronous belt, which not only maintains the stability of the movement of the rotating frame, but also ensures the synchronous movement of the rotating frames on both sides through the transmission characteristics of the synchronous belt, avoiding the disassembly roller from tilting or getting stuck. The guide wheel presses the synchronous belt at the same time, enhancing the tension stability of the transmission system, preventing the synchronous belt from slipping, and indirectly ensuring the power transmission efficiency of the limit mechanism and the driving roller.The second servo motor serves as the power source of the slitting mechanism. After starting, it outputs stable rotational power. The output end of the motor is fixedly connected to the rotating shaft. Multiple crankshafts evenly distributed on the rotating shaft rotate synchronously with the rotating shaft, converting the circular motion of the rotating shaft into the eccentric rotation of the crankshafts. The crankshafts are movably connected to the curved rods. The lower end of the curved rod is hinged to the crankshaft, and the upper end is fixedly connected to the circular knife, which will push the curved rod to perform reciprocating linear motion in the guide groove. The position of the slitting hole corresponds to the movement trajectory of the circular knife, and the hole diameter is slightly larger than the diameter of the circular knife, providing a passage for the circular knife to cut. The diaphragm base film conveyed by the limiting mechanism and the conveying rollers passes above the slitting hole. When the circular knife moves downward driven by the curved rod, the blade passes through the slitting hole to cut the diaphragm. After the circular knife rises and resets, one slitting action is completed. The setting of multiple circular knives and slitting holes can achieve multi-knife synchronous slitting of the diaphragm, greatly improving the slitting efficiency. The slitting mechanism precisely controls the rotation speed of the rotating shaft through the second servo motor, thereby adjusting the cutting frequency of the circular knife. Combining with the conveying speed of the diaphragm, the slitting length and slitting quality can be accurately controlled. Description of the drawings.

A winding frame 11 is fixedly connected to one side of the workbench 1. A plurality of winding rollers 7 are arranged at equal intervals on the winding frame 11. A slitting mechanism 8 is arranged on one side of the workbench 1 with respect to the winding frame 11; In this embodiment, specifically, the limiting mechanism 3 includes a transmission shaft 301, a movable sleeve 302, a bearing seat 303, a driving wheel 304, a synchronous belt 305, an adjustment groove 306, an adjustment block 307, a transmission rod 308, a limiting seat 309, a connecting member 310, an upper pressing plate 311, a lower pressing plate 312, a reciprocating lead screw 313 and a first servo motor 315. One side of the workbench 1 is fixedly connected with a first servo motor 315. The output end of the first servo motor 315 is provided with a transmission shaft 301 inside the workbench 1. The transmission shaft 301 is provided with bearing seats 303 on the workbench 1. Driving wheels 304 are arranged on one side of the transmission shaft 301 close to the bearing seats 303. And a limiting seat 309 is fixedly connected to one side of the workbench 1 close to the tension sensing shaft 6. Two groups of limiting seats 309 are symmetrically arranged. A transmission groove 314 is formed on one side of the workbench 1 at the limiting seat 309. And adjustment grooves 306 are symmetrically formed between the limiting seats 309 on the workbench 1. Reciprocating lead screws 313 are movably connected in the adjustment grooves 306. Adjustment blocks 307 are movably connected to the reciprocating lead screws 313. And one end of the reciprocating lead screw 313 is fixedly connected with a transmission wheel 316 in the transmission groove 314. A synchronous belt 305 is sleeved between the driving wheel 304 and the transmission wheel 316; An upper pressing plate 311 is slidably connected between the two limiting seats 309. Connecting members 310 are symmetrically arranged below the upper pressing plate 311. Transmission rods 308 are movably connected to the connecting members 310. One end of the transmission rod 308 far from the connecting member 310 is movably connected with an adjustment block 307. A lower pressing plate 312 is arranged on one side of the workbench 1 close to the adjustment groove 306. Gaskets are arranged on the surfaces of the upper pressing plate 311 and the lower pressing plate 312. The gaskets are made of rubber materials; Taking the first servo motor 315 as a power source, after starting, it outputs power to drive the transmission shaft 301 to rotate. The transmission shaft 301 realizes stable support and rotation by means of the bearing seats 303 at both ends, ensuring the smoothness of power transmission. Driving wheels 304 are installed at positions of the transmission shaft 301 close to the bearing seats 303. The driving wheels 304 rotate synchronously with the transmission shaft 301 and transmit power to the transmission wheel 316 through the synchronous belt 305. The transmission wheel 316 is fixed to one end of the reciprocating lead screw 313 and is located in the transmission groove 314 formed on the workbench 1. In this way, a power transmission link from the first servo motor 315 to the reciprocating lead screw 313 is formed. In this transmission system, the synchronous belt 305 not only realizes reliable power transmission, but also uses its synchronous transmission characteristics to ensure that the rotational speeds between the driving wheel 304 and the transmission wheel 316 are consistent, thereby ensuring that multiple reciprocating lead screws 313 rotate synchronously, providing a stable basis for subsequent adjustment actions; When the reciprocating lead screw 313 rotates under the drive of power, the adjusting block 307 movably connected thereto will perform a linear motion along the adjusting groove 306. Since the adjusting groove 306 is symmetrically arranged between the two groups of limiting seats 309 and the reciprocating lead screw 313 is installed inside, the movement of the adjusting block 307 is guided and restricted by the adjusting groove 306. By controlling the rotation direction and speed of the first servo motor 315, the moving distance and speed of the adjusting block 307 can be accurately controlled. The linear motion of the adjusting block 307 is transmitted to the upper pressing plate 311 through the transmission rod 308 and the connecting member 310. When the adjusting block 307 moves, it drives the transmission rod 308 to swing, and then pushes the connecting member 310 and the upper pressing plate 311 to slide between the two groups of limiting seats 309, forming an upper and lower clamping structure with the lower pressing plate 312. When clamping the diaphragm master roll, it can not only ensure the reliable fixation of the master roll and prevent its displacement or sliding during the slitting process, but also avoid damaging the diaphragm due to excessive clamping force, ensuring the integrity of the diaphragm and the slitting quality. During the actual working process, the operator can set the operating parameters of the first servo motor 315 through the control system according to the specifications of the master roll, adjust the upper pressing plate 311 and the lower pressing plate 312 to an appropriate distance, and accurately limit the diaphragm master roll, providing a stable and reliable basic condition for the subsequent synchronous conveying and slitting processes.

When the rotating frame 401 moves axially along the transmission shaft 301, the guide wheel 403 rolls on the synchronous belt 305, which not only maintains the movement stability of the rotating frame 401, but also ensures the synchronous movement of the rotating frames 401 on both sides through the transmission characteristics of the synchronous belt 305, avoiding the disassembly roller 5 from tilting or getting stuck. The guide wheel 403 also presses the synchronous belt 305 to enhance the tension stability of the transmission system and prevent the synchronous belt 305 from slipping, thereby indirectly ensuring the power transmission efficiency between the limiting mechanism 3 and the drive shaft 10.
