Description

TECHNICAL FIELD

[0001] The application relates to the technical field of aluminum strip shearing, and particularly relates to an aluminum strip shearing fine adjustment structure based on visual data. BACKGROUND

[0002] High-precision slitting products of aluminum materials (such as lithium battery packaging materials) require a cutting edge error of less than 0.05 mm, and the market share is increasing year by year. In the aluminum strip slitting process, the degree of wear of the cutting knife, the lubrication state and the matching precision of the cutting knife and the cutting groove directly affect the slitting quality and production efficiency. However, the traditional slitting equipment has significant deficiencies in dynamic fine adjustment, mainly relying on manual intervention or static design, which is difficult to meet the requirements of modern production lines for high efficiency, precision and automation, resulting in low production efficiency, high maintenance cost and unstable product quality.

[0003] The existing aluminum strip slitting equipment usually adopts a mechanical fixed cutter structure, is equipped with a manual or semi-automatic maintenance mechanism, and is widely used in small and medium-sized processing plants and mass production lines. Typical equipment includes a traditional disc shear and a fixed knife group slitting machine, and the core technology thereof depends on mechanical transmission and manual adjustment. For example, the disc shear cuts the aluminum strip through a plurality of fixed cutting knives, the position of the cutting knife is fixed by mechanical limiting, lubrication is achieved by manually applying lubricating oil at regular intervals, and the matching of the cutting knife and the cutting groove depends on the preset mechanical gap. Such equipment performs well in low-precision scenarios (such as building material slitting, with an error requirement of 0.1 mm or more), but has obvious defects in high-precision scenarios (such as electronic component packaging, with an error requirement of less than 0.05 mm). The specific limitations of the prior art include the following aspects: Lack of automation in cutter replacement: the existing equipment cannot monitor the wear state of the cutting knife in real time, and usually replaces the cutting knife through manual regular inspection or according to the production batch plan. The inspection process needs to be stopped, and the time for a single replacement is 5 to 10 minutes, which significantly reduces the production efficiency. If the wear is not found in time, the dulling or notching of the cutting knife will increase the cutting edge error to more than 0.1 mm, affecting the product quality and increasing the scrap rate.

[0004] Inaccurate lubrication adjustment: the traditional equipment relies on manual or timing lubrication devices, and the lubricating oil application frequency and amount cannot be dynamically adjusted according to the actual state of the cutting knife. For example, the fixed oil spraying device sprays more than 0.2 ml of lubricating oil each time, which is easy to cause waste or uneven coverage. When the oil film thickness is less than 0.1 mm, the friction will increase, the service life of the cutting knife will be shortened, and the cutting edge quality will be difficult to stabilize for a long time.

[0005] The cutter and the cutting groove are not matched: the existing equipment is usually designed statically, the cutter is usually straight or simple geometric shape, and the cutting groove is fixed circular ring with a gap of more than 0.05 mm, lacking dynamic alignment mechanism. When the cutting speed is higher than 0.5 m / s or the thickness of the aluminum strip is different (such as 0.2 to 1 mm), the cutter is easy to deviate or vibrate slightly, resulting in uneven cutting edge and high error of up to 0.15 mm, which is difficult to meet the high precision requirement.

[0006] Low degree of intelligence: the existing equipment lacks real-time monitoring and feedback mechanism based on visual data, and cannot dynamically obtain tool wear or lubrication state information. Some equipment is equipped with simple sensors (such as pressure or temperature sensors), but only for fault alarm, and it is difficult to realize accurate fine tuning control. Especially in continuous production, the influence of aluminum strip material or environmental changes (such as temperature and humidity) on the cutting effect cannot be corrected in time, resulting in quality fluctuation.

[0007] Therefore, an aluminum strip shearing fine tuning structure based on visual data is needed to solve the above problems. SUMMARY

[0018] A plurality of sleeve grooves 28 are arranged on the outside of the cutter shaft 13, the specific number is set according to the actual situation, and a cutter sleeve 26 is sleeved in each sleeve groove 28. It should be noted that the cutter sleeve 26 can be divided into two halves, which is convenient for installation on the cutter shaft 13. Each cutter sleeve 26 on the cutter shaft 13 can rotate independently, which is convenient for replacement. Under normal circumstances, the cutter sleeve 26 is limited by the elastic clamping column 29 in the sleeve groove 28. When it is necessary to rotate a certain cutter sleeve 26, the elastic clamping column 29 in the corresponding sleeve groove 28 is controlled to retract. The elastic clamping column 29 is controlled by a pneumatic cylinder. After retraction, the corresponding cutter sleeve 26 can rotate. The whole cutting assembly is installed on the moving sliding block 24. The moving sliding block 24 can slide in the cross-shaped sliding groove 23 of the mounting plate 15. The height and front and back position of the whole cutting assembly can be adjusted by a screw structure.

[0019] The inside of the groove 30 is movably connected to an opening and closing arc plate 31. A micro motor 32 is installed on one side of the distal end of the opening and closing arc plate 31. The opening and closing arc plate 31 is controlled to flip by the micro motor 32. The front end of the opening and closing arc plate 31 is clamped with a cutter 33, and the cutter 33 is reinforced by bolts. The front end of the cutter 33 is provided with a cutting knife 34. The cutting knife 34 and the cutter 33 are integrated.

[0020] The opening and closing arc plates 31 in the grooves 30 on the top and the bottom of each cutter sleeve 26 can be unfolded, as shown in the attached drawings. Figure 9As shown, the left side is the open state of the knife sheath 26, the right side is the initial state of the knife sheath 26, which is stored in the opening slot 30 when the opening and closing arc plate 31 is not unfolded, the top cutting knife 34 is the normal cutting assembly, and the bottom is the standby.

[0021] The structure of the top and bottom opening slots 30 in the knife sheath 26 is exactly the same. The two sides and the top and bottom of the knife sheath 26 are provided with limiting insertion holes 35. The limiting insertion holes 35 and the telescopic clamping columns 29 are matched with each other. The two side edges of the knife sheath 26 are provided with straight tooth patterns 27. The front surface of the rear pasting plate 25 is provided with a square slot. The square slot on the front surface of the rear pasting plate 25 is aligned with the position of the knife sheath 26, and the back one-third of the knife sheath 26 is located inside the square slot. The two sides of the square slot on the front surface of the rear pasting plate 25 are both provided with bevel gear sets 36. The bevel gear sets 36 are both controlled by motors. The bevel gear sets 36 on the two sides of the square slot are respectively meshed with the straight tooth patterns 27 on the two sides of the knife sheath 26.

[0022] When the cutting knife 34 needs to be replaced, the telescopic clamping column 29 will be retracted by controlling the cylinder at the end of the telescopic clamping column 29, so that the telescopic clamping column 29 will be pulled out of the limiting insertion hole 35 in the knife sheath 26, so that the rotation of the knife sheath 26 is cancelled, and then the corresponding micro motor 32 is controlled to open or close. A part of the back of each knife sheath 26 is located in the corresponding square slot of the rear pasting plate 25. When rotating, the bevel gear sets 36 on the two sides of the corresponding square slot are controlled to rotate. The rotation of the bevel gear sets 36 will drive the corresponding knife sheath 26 to rotate through the meshing with the straight tooth patterns 27. When the cutting knife 34 assembly is adjusted each time, the knife sheath 26 is indirectly rotated counterclockwise by one hundred and eighty degrees through the bevel gear sets 36. In this way, the bottom cutting knife 34 assembly will be adjusted to the corresponding position.

[0023] The material passing roller group 16 includes a material passing roller body 22. The surface of the material passing roller body 22 is provided with a cutting groove 37. The outer shape of the cutting groove 37 is a circular ring. Figure 13 As shown in the bottom, it is the internal schematic diagram of the cutting groove 37. The two side trapezoidal areas will be pushed upward by a force, and the two side trapezoidal areas will be adapted and combined with the bottom of the cutting knife 34. The two sides of the bottom of the cutting knife 34 are also trapezoidal but upside down.

[0024] The side of the shearing table 1 is provided with a lubricating oil bottle 12, the top of the shearing table 1 is provided with a tool holder 11 near the material passing roller group 16, the bottom of the tool holder 11 is slidably connected with a sliding block 18, one side of the sliding block 18 is provided with a metering pump 21, one side of the metering pump 21 and the lubricating oil bottle 12 are connected with an oil suction pipe 17, the bottom of the sliding block 18 is provided with a connecting pipe 19, the connecting pipe 19 and the metering pump 21 are connected in the sliding block 18, and the bottom end of the connecting pipe 19 is provided with an oil dripping pipe 20. The lubricating oil bottle 12 is filled with lubricating oil.

[0025] The side of the shearing table 1 is provided with a first feeding roller group 6, one side of the first feeding roller group 6 is provided with a second feeding roller group 8, one side of the second feeding roller group 8 is provided with a third feeding roller group 9, one side of the third feeding roller group 9 is provided with a material feeding roller group 10, and the side edges of the first feeding roller group 6, the second feeding roller group 8, the third feeding roller group 9 and the material feeding roller group 10 are provided with driving motors 5.

[0026] The bottom edge of the tool holder 11 is provided with a tool wear monitoring probe 38 and a lubricating state monitoring probe 39.

[0027] The back side of the shearing table 1 is provided with a main control machine 7, the images collected by the tool wear monitoring probe 38 and the lubricating state monitoring probe 39 at the bottom edge of the tool holder 11 are transmitted to the main control machine 7 in real time, and the main control machine 7 analyzes the acquired images.

[0028] The lubricating state monitoring probe 39 monitors the position of the cutting tool 34 in real time, and transmits the images to the main control machine 7 in real time. When the main control machine 7 analyzes the images and finds the required cutting tool 34, the sliding block 18 is first moved to the top of the corresponding cutting tool 34. It should be noted that the sliding block 18 is controlled by a screw structure and can slide forward and backward. After moving to the corresponding position, the metering pump 21 is started, and the appropriate amount of lubricating oil is pumped through the metering pump 21 and the oil suction pipe 17, then input into the connecting pipe 19, and finally dripped onto the corresponding cutting tool 34 at the bottom through the oil dripping pipe 20.

[0029] The whole aluminum strip runs as shown in the figure Figure 5As shown, the aluminum strip will be placed on the feeding roller group 10 during processing. The aluminum strip will first pass through the top of the third feeding roller group 9, which will smooth the bottom of the aluminum strip. Then the aluminum strip will continue to pass through the gap between the side edges of the third feeding roller group 9 and the second feeding roller group 8, and then pass through the bottom of the second feeding roller group 8. After that, the aluminum strip will pass through the gap between the second feeding roller group 8 and the first feeding roller group 6, and then pass through the top of the first feeding roller group 6. After that, the long feeding will come to the surface of the feeding roller group 16. The cutter 34 will cut the aluminum strip on the feeding roller group 16. The cut aluminum strip will pass between the smoothing roller group 14 and the receiving roller group 2. The smoothing roller group 14 will smooth the cut aluminum strip. The first winding roller group 3 and the second winding roller group 4 have the same function, which is to wind the finished product. However, one is a backup and can be used to wind different batches of finished products.

[0030] It should be noted that the fine tuning of the present technical solution mainly reflects the real-time monitoring of the cutter 34 wear and lubrication state through visual data, the automatic triggering of the 180-degree rotation of the cutter sleeve 26 to replace the cutter and the precise lubrication operation, and the multi-dimensional adjustment of the moving slide 24 in the cross slide 23, which ensures the precise alignment of the cutter 34 and the cutting groove 37 and maintains the cutting accuracy less than 0.05 mm. Specific embodiment two: As Figures 1 to 14 shown, the following is a detailed description of the complete working principle of the aluminum strip cutting fine tuning structure based on visual data, covering cutter wear monitoring, lubrication system, and automatic cutter replacement process: The aluminum strip cutting fine tuning structure takes the cutting table 1 as the core. The aluminum strip starts from the feeding roller group 10, passes through the third feeding roller group 9, the second feeding roller group 8, and the first feeding roller group 6 for transportation and preliminary smoothing, enters the surface of the feeding roller group 16 for cutting, and the cut aluminum strip passes through the smoothing roller group 14 and the receiving roller group 2 to complete the finished product collection. The second winding roller group 4 serves as a backup winding device. The main control machine 7 collects images through the cutter wear monitoring probe 38 and the lubrication state monitoring probe 39, analyzes the cutter state and lubrication demand in real time, automatically performs cutter 34 replacement and lubrication operation, and ensures cutting accuracy and equipment stability.

[0032] Tool wear monitoring is performed by a tool wear monitoring probe 38 mounted on the bottom edge of the platen 11, a Basler acA1300-60gm industrial camera with a resolution of 1280x1024 pixels and a frame rate of 60 frames per second, equipped with a Gigabit Ethernet interface, coupled with a Computar M1614-MP2 fixed-focus lens with a focal length of 16 mm and an aperture of F1.4. The camera captures the surface of the cutting knife 34 at a frequency of 5 frames per second via a Category 6 network cable using the Transmission Control Protocol / Internet Protocol, and the image data is transmitted to the main control computer 7. The main control computer 7 is an Advantech MIC-770 V2 embedded industrial computer equipped with an Intel Core i7-8700 processor, 16 gigabytes of fourth-generation double data rate random access memory, a 512-gigabyte non-volatile memory solid-state drive, and runs the Ubuntu 20.04 operating system, integrated with OpenCV 4.5.5 and PyTorch 1.12.0 for image processing and deep learning.

[0033] The image processing flow is as follows: the camera captures the red-green-blue image of the cutting knife 34 at a resolution of 1280x1024 pixels, a frame rate of 5 frames per second, and an exposure time of 1 / 1000 second, with a CCS LDL2-74X30SW2 white light-emitting diode light source with a color temperature of 6500 Kelvin to eliminate environmental light interference and highlight the details of the cutting edge. The red-green-blue image is converted to a grayscale image, simplifying the three-channel color information to single-channel brightness information to reduce computational complexity. Gaussian blur is used to process noise by weighting the brightness of each pixel with its surrounding pixels using a 5x5 pixel kernel with a standard deviation of 1.5 to smooth high-frequency noise such as metal reflections or small particles. The edge detection identifies the cutting edge profile by calculating the brightness gradient in the image, marking significant changes as edges, generating a binary edge map that highlights the geometric shape of the cutting knife 34 and potential wear areas such as cracks or gaps.

[0034] The wear analysis consists of two parts: first, by template matching, a pre-stored ideal cutter 34 profile template is used, represented in pixelized contour, the template contains the standard shape and size of the cutting edge. The algorithm slides the template over the edge map, compares the brightness correlation pixel by pixel, calculates the similarity, the method is to multiply the pixel values of the template and the corresponding area of the edge map one by one, normalize the sum to get the correlation coefficient, the range is 0 to 1, the lower the value, the greater the deviation. The deviation is manifested as an increase in the width of the cutting edge, for example, an increase of 10 pixels, about 0.1 mm, or an edge missing, for example, a continuous 5-pixel missing, indicating wear, such as dullness or notch. Second, a YOLOv5s deep learning model is used, pre-trained on a cutter wear dataset containing 5000 labeled images, covering three types of defects: cracks, dullness and notches. The input is a grayscale image, the model divides the image into an 8x8 grid, and each grid predicts the bounding box of the defect area, the output includes the defect type (crack, dullness, notch), the bounding box coordinates (horizontal coordinate, vertical coordinate, width, height) and the confidence (0 to 1). The training process uses 100 cycles, batch size 16, and inference takes about 50 milliseconds per frame, running on NVIDIA CUDA accelerated graphics processing units. Wear quantification is based on edge map calculation of cutting edge width change, unit pixel, converted to actual size, 1 pixel equals 0.01 mm, for example, a 5-pixel increase in width is 0.05 mm; the YOLOv5 model measures the notch depth or crack length, based on the height or width of the bounding box, converted to millimeters. The default threshold is: notch depth greater than 0.2 mm or cutting edge width increase more than 5%, judged as excessive wear.

[0035] When excessive wear of a certain cutter 34 is detected, the main control machine 7 generates a replacement instruction, records the number of the tool holder 26, for example K1, and its position on the tool shaft 13, for example the 3rd slot, stored in the SQLite database, containing the timestamp, tool holder number, wear type and degree. The instruction is transmitted to the control module Beckhoff CX5130 of the tool shaft 13 through the EtherCAT protocol, with a transmission delay of less than 1 millisecond. Beckhoff CX5130 is an embedded controller equipped with a 32-bit processor, 2 gigabytes of random access memory, running TwinCAT 3 software, receiving EtherCAT data packets, the data packet format is JavaScript Object Notation, containing the target tool holder number, the action sequence (unlock, close the arc plate, rotate the tool holder, open the arc plate, reposition) and the priority. CX5130 parses the data packet through the internal input / output module, decomposes the instruction into sub-tasks, and assigns them to the execution components: the micro-cylinder of the tool shaft 13, the micro-motor of the tool holder 26 and the servo motor of the moving slide 24.

[0036] The cutter 34 replacement is achieved by the cooperation of the cutter shaft 13, the cutter sleeve 26 and the opening and closing arc plate 31. The main control machine 7 sends the replacement instruction to the CX5130 through EtherCAT, and the CX5130 decomposes the instruction into subtasks and sends it to the corresponding components through the digital output module. The telescopic clamping column 29 in the surface sleeve groove 28 of the cutter shaft 13 is driven by the SMC CDJ2B10-30-B micro cylinder, with a stroke of 30 mm and a response time of 0.1 seconds. The CX5130 sends a 24-volt digital signal to the electromagnetic valve of the cylinder through EtherCAT, triggering the cylinder to retract the clamping column 29, pulling out the cutter sleeve 26 from the limiting hole 35, and releasing the rotation restriction. The limiting hole and the clamping column are matched with a tolerance of H7 / g6, which ensures that the cutter sleeve 26 cannot rotate freely in the unlocked state. The opening and closing arc plate 31 at the top and bottom of the cutter sleeve 26 is driven by the Faulhaber 2224U012SR DC brushless motor, with a torque of 0.02 Nm and a 4096-pulse encoder. The CX5130 sends a pulse width modulation signal to the motor driver to control the motor to rotate counterclockwise, closing the top opening and closing arc plate 31 into the slot 30, with an angle of 0 degrees. The opening and closing arc plate 31 is connected to the cutter sleeve through a hinge, with a spring built-in, a stiffness coefficient of 5 N / mm, and an encoder-controlled error of 0.5 degrees. The back one-third of the cutter sleeve 26 is embedded in the square slot of the rear plate 25, and the KHK SSG2-30 bevel gear set on both sides of the square slot, with a module of 2 and 30 teeth, is engaged with the linear tooth 27 on both sides of the cutter sleeve, driven by the Mitsubishi MR-JE-20A servo motor, with a power of 200 W and an encoder resolution of 131072 pulses. The CX5130 sends a target angle instruction, sets 180 degrees, and the servo motor drives the gear set to rotate, driving the cutter sleeve to rotate counterclockwise by 180 degrees, adjusting the bottom standby cutter to the top. The encoder feedback ensures the rotation accuracy, with an error of 0.1 degrees. After rotation, the CX5130 controls the micro motor to rotate clockwise, opening the new top opening and closing arc plate 31 to 90 degrees, and aligning the front end of the cutter 34 with the cutting slot 37 of the material passing roller body 22.

[0037] The fitting mechanism of the cutter 34 and the cutting groove 37 is as follows: the bottom of the cutter 34 is an inverted trapezoidal structure, with a bottom width of 10 mm, a top width of 6 mm, an inclined edge angle of 15 degrees, a height of 3 mm, and a material of high-speed steel with a surface hardness of HRC60. The cutting groove 37 is located on the surface of the material passing roller body 22, which is an annular groove with two trapezoidal sides inside, a bottom width of 6 mm, a top width of 10 mm, an inclined edge angle of 15 degrees, a depth of 3 mm, a material of 45 steel, a surface coated with a polytetrafluoroethylene coating, and a friction coefficient of 0.1. The inverted trapezoidal bottom of the cutter 34 precisely fits the trapezoidal inside of the cutting groove 37, with a contact surface tolerance of 0.02 mm, ensuring no gap. The cutting groove 37 is equipped with a spring mechanism that provides an upward thrust of 10 Newton, ensuring that the inside of the cutting groove and the bottom of the cutter are in close contact. The fitting action includes: first, the trapezoidal structure ensures that the cutter 34 is precisely embedded in the cutting groove 37 during slitting, limiting the lateral deviation of the cutter, improving the slitting accuracy, and reducing the cutting edge error of the aluminum strip to less than 0.05 mm; second, the 10 Newton thrust maintains the stable contact between the cutter and the cutting groove, reduces vibration, prevents the cutter from jumping, and ensures the smoothness of the cut; finally, the polytetrafluoroethylene coating reduces friction and wear of the cutter, prolonging its service life. The fitting of the cutter 34 and the cutting groove 37 is further optimized by the precise positioning of the cutter shaft 13 and the moving slide plate 24, with the CX5130 sending the target position of the horizontal and vertical axes, such as 10 mm in the horizontal axis and 5 mm in the vertical axis, the Mitsubishi MR-JE-40A servo motor driving the THK KR33 lead screw with a lead of 10 mm and a positioning accuracy of 0.01 mm, adjusting the movement of the slide plate 24 in the cross slot 23 of the mounting plate 15, ensuring the alignment of the cutter 34 and the cutting groove 37, with an adjustment range of ±50 mm in the horizontal axis and ±30 mm in the vertical axis. The worn cutter is stored in the bottom slot 30, waiting for manual replacement after shutdown, and the cutter 33 is fixed to the opening and closing arc plate 31 by M6 bolts with a grade of 8.8, facilitating disassembly.

[0038] The lubrication system is implemented through a lubrication state monitoring probe 39 and a lubricating oil supply mechanism. The probe 39 is a Keyence IV2-G500CA equipped with a 2048x1536 pixel complementary metal oxide semiconductor sensor, integrated with an artificial intelligence analysis module, captures the lubrication state of the cutting knife 34 surface, frame rate 5 frames per second, transmitted to the main control machine 7 through a gigabit Ethernet interface. The main control machine analyzes the image gray intensity, calculates the lubricating oil coverage rate, for example, the pixel area ratio with brightness lower than 100, combined with the texture pattern, based on the local brightness variance, evaluates the oil film uniformity. The threshold is set to the oil film thickness below 0.1 millimeter, corresponding to the gray value below the preset baseline, or the coverage rate below 80%, triggers the lubrication demand. The main control machine generates lubrication instructions, records the knife cover 26 number and position, transmitted to the CX5130 through EtherCAT with a delay of 0.5 milliseconds. The CX5130 analyzes the instructions, allocates tasks to the sliding block 18 and the metering pump through the input / output module. The lubricating oil bottle 12 stores Mobilcut 100 cutting lubricating oil, connected to the Graco D31255 metering pump through the oil suction pipe 17, flow accuracy 1%. The sliding block 18 at the bottom of the support plate 11 is driven by the THK KR20 screw, lead 5 millimeters, controlled by the Mitsubishi MR-JE-20A servo motor. The CX5130 sends the target position, for example, 15 millimeters on the horizontal axis 15, the servo motor moves the sliding block 18 to the top of the target cutting knife 34, the pump extracts 0.05 to 0.1 milliliter of lubricating oil, and drops it to the cutting knife surface through the connecting pipe 19 and the 0.5 millimeter inner diameter stainless steel oil dripping tube 20, the nozzle ensures uniform distribution. After lubrication, the probe 39 takes another picture, and the main control machine analyzes the lubrication effect. If it does not meet the standard, repeat the lubrication, if it meets the standard, record the completion status.

[0039] The aluminum strip starts from the feeding roller group 10, driven by the Siemens 1FK7042 motor, power 0.75 kilowatts, transported and smoothed through the third feeding roller group 9, the second feeding roller group 8, the first feeding roller group 6, and enters the surface of the passing roller group 16. The cutting knife 34 is cut in the cutting groove 37, which is attached by a 10 newton upward force. The cut aluminum strip is collected by the smoothing roller group 14 and the receiving roller group 2, and the second roll group 4 is standby. The opening and closing arc plate 31 is ensured to be tightly attached to the slot 30 when closed by the spring, and cannot be rotated when the motor is not driven. The knife cover is split in half, with a public tolerance of H7 / g6, and is fixed by M8 bolts. The main control machine monitors the motor and probe state, and alarms and pauses when abnormal. The EtherCAT protocol delay is less than 1 millisecond, and the data packet contains instruction type, target number and timestamp. The system realizes real-time management of the cutting tool and lubrication state through visual analysis, 180 degree knife cover rotation and 90 degree arc plate expansion ensure fast cutting knife replacement, precise lubrication prolongs tool life, accurate adaptation of cutting knife and cutting groove improves cutting accuracy, multi-dimensional adjustment adapts to different aluminum strip specifications, and EtherCAT transmission ensures efficient control.

[0040] Hardware models include: tool wear monitoring probe Basler acA1300-60gm with Computar M1614-MP2 lens, lubrication condition monitoring probe Keyence IV2-G500CA, main controller Advantech MIC-770 V2, control module Beckhoff CX5130, micro cylinder SMC CDJ2B10-30-B, micro motor Faulhaber 2224U012SR, servo motors Mitsubishi MR-JE-20A and MR-JE-40A, helical gear set KHK SSG2-30, lead screws THK KR33 and KR20, metering suction pump Graco D31255, drive motor Siemens 1FK7042. Specific embodiment three: like Figures 1 to 14 As shown, the following is a supplement to the details of the above embodiment: Connection details for the cutter 34 and blade 33: The cutter 34 and blade 33 are manufactured using an integrated molding process using high-speed steel (HSS). The blade 33 has a rectangular base, measuring 20 mm wide, 5 mm thick, and 50 mm long. The blade 34 features a sharp cutting edge at the front with a 30-degree angle and a length of 10 mm, ensuring high strength and stability. The blade 33 is secured to the opening and closing arc plate 31 with two M6 bolts (grade 8.8, torque 10 Nm). The 2 mm deep groove precisely matches the base of the blade 33, with a tolerance of H7 / g6 to prevent loosening. This ensures a secure fit during slitting and transmits cutting force to the aluminum strip, resulting in a trimming error of less than 0.05 mm.

[0042] Hinge details for the opening and closing arc plate 31: The opening and closing arc plate 31 is connected to the blade housing 26 via a stainless steel hinge with a diameter of 5 mm and a length of 15 mm. It is fixed to the inside of the slot 30 and connected to the opening and closing arc plate 31 by two micro pins (2 mm diameter). The hinge incorporates a helical compression spring with a diameter of 4 mm, a wire diameter of 0.5 mm, and 10 turns, providing a stiffness of 5 Newtons per millimeter. This ensures that the arc plate adheres tightly to the inner wall of the slot 30 when closed, preventing loosening or vibration. The hinge has a rotation range of 0 to 90 degrees and a built-in stop to prevent over-rotation. A micro motor 32 (Faulhaber 2224U012SR, torque of 0.02 Nm, 4096 pulse encoder) is connected to the hinge via a 0.5 modulus, 10-tooth gear drive. This controls the tilting of the arc plate, ensuring that the cutter 34 is aligned with the slot 37 with a tolerance of 0.5 degrees when extended to 90 degrees, with a rotation response time of 0.2 seconds.

[0043] The installation and fixing mechanism of the half-split knife sleeve 26: The knife sleeve 26 is a circular ring with a diameter of 50 mm and a thickness of 10 mm, made of 45 steel, divided into two halves, and the contact surface is ensured to be seamlessly fitted through high-precision plane milling (flatness 0.01 mm). The two halves are fixed by four M8 bolts (8.8 level, torque 20 Nm), with bolt holes on the outside of the knife sleeve, hole diameter 8.2 mm, evenly distributed on the circumference. When installing, the two halves of the knife sleeve 26 are folded around the sleeve groove 28 of the knife shaft 13, and the bolts are tightened to form a complete circular ring, concentric with the knife shaft 13, with a tolerance of H7 / g6. When disassembling, loosen the bolts for easy replacement or maintenance, the installation process takes about 2 minutes, ensuring that the knife sleeve 26 does not shift during slitting and maintaining the accuracy of the cutter 34 position.

[0044] Spring mechanism details of the material roller body 22: The spring mechanism in the cutting groove 37 is composed of multiple parallel compression springs, made of stainless steel, with a diameter of 3 mm and a wire diameter of 0.4 mm, 12 turns, distributed every 10 mm along the circular cutting groove, a total of 30 springs, fixed to the 45 steel bottom plate (thickness 2 mm, bolted inside the material roller body 22). The spring provides an upward force of 10 Newton, with a compression of 0.5 mm, acting on the inner side of the right trapezoid of the cutting groove 37 (base 6 mm, top 10 mm, inclination 15 degrees), ensuring close contact with the inverted trapezoidal bottom of the cutter 34 (base 10 mm, top 6 mm, inclination 15 degrees), with a contact surface tolerance of 0.02 mm, coated with a polytetrafluoroethylene coating, with a friction coefficient of 0.1. The spring mechanism maintains stable contact between the cutter 34 and the cutting groove 37, reduces vibration during slitting, ensures smooth cutting, extends the life of the cutter, and the cutting edge error is less than 0.05 mm.

[0045] Control and coordination of driving motors 5: The driving motors 5 (Siemens 1FK7042, power 0.75 kW) of the first feeding roller group 6, the second feeding roller group 8, the third feeding roller group 9, and the feeding roller group 10 are controlled by independent frequency converters (Siemens G120, rated power 1 kW), with a rotation speed range of 0-1500 rpm and an accuracy of ±1 rpm. The main control machine 7 (Advantech MIC-770 V2, Intel Core i7-8700 processor, 16 GB fourth-generation double data rate random access memory, 512 GB non-volatile memory solid state drive) sends rotation speed instructions to the frequency converter through the EtherCAT protocol, with instructions including target rotation speed (e.g., 1000 rpm) and start time (delay 0.2 seconds), and data packet format JavaScript Object Notation. The frequency converter adjusts motor voltage and frequency through pulse width modulation to ensure synchronous operation of each roller group, with aluminum strip conveying speed stabilized at 0.5 m / s, with an error of ±0.01 m / s. The Beckhoff CX5130 controller (32-bit processor, 2 GB random access memory, running TwinCAT 3 software) coordinates the motors, monitors rotation speed through closed-loop feedback, prevents aluminum strip stretching or relaxation, and ensures smooth conveying.

[0046] Drive mechanism of cross slide 23 and moving slide plate 24: The cross slide 23 is a T-shaped slot with a width of 20 mm and a depth of 10 mm, made of 45 steel with surface hardening treatment (HRC 50), located on the front of the mounting plate 15, divided into horizontal and vertical tracks to support the movement of the moving slide plate 24 in the horizontal axis (X axis, ±50 mm) and the vertical axis (Y axis, ±30 mm). The moving slide plate 24 is a rectangular steel plate with dimensions 100 mm x 80 mm x 20 mm, driven by a THK KR33 lead screw with a lead of 10 mm and a positioning accuracy of 0.01 mm, equipped with a Mitsubishi MR-JE-40A servo motor (power 400 W, encoder resolution 131072 pulses). The CX5130 sends target position instructions through EtherCAT, such as horizontal axis 10 mm, vertical axis 5 mm, which are decomposed into pulse width modulation signals to drive the servo motor to rotate the lead screw, moving the moving slide plate 24 along the cross slide 23, adjusting the position of the cutting assembly, ensuring that the cutter 34 is aligned with the cutting groove 37. Each axis is equipped with a lead screw to control forward and backward movement and upward and downward movement, with a response time of 0.3 seconds and a positioning error of 0.01 mm, ensuring cutting accuracy. Specific embodiment four: As Figures 1 to 14 shown below are specific use cases: Use case: Knife wear monitoring and automatic replacement in aluminum strip cutting production line: Scenario: An aluminum strip processing factory uses a vision-based aluminum strip trimming structure to process 500mm wide aluminum strips, which are cut into 50mm wide strips for manufacturing electronic component packaging materials. The system needs to ensure that the cutting edge is flat, with an error of less than 0.05mm, while automatically monitoring and replacing the cutting tool to maintain production efficiency.

[0048] Operation flow: Aluminum strip conveying and cutting: The aluminum strip is loaded from the upper roll group 10, and the third feed roll group 9, the second feed roll group 8, and the first feed roll group 6 are driven by the drive motor 5 (Siemens 1FK7042) to convey the aluminum strip to the surface of the feed roll group 16 at a speed of 0.5 meters per second. The aluminum strip is smoothed by the roll group during conveying, enters the feed roll body 22, and the cutting tool 34 is inserted into the cutting groove 37 for cutting. After cutting, the aluminum strip is collected by the smoothing roll group 14 and the receiving roll group 2, and the second roll group 4 is standby.

[0049] Tool wear monitoring: The tool wear monitoring probe 38 (Basler acA1300-60gm industrial camera) takes 5 frames per second of the surface of the cutting tool 34, and the image is transmitted to the main control machine 7 (Advantech MIC-770 V2) through Category 6 network cable. The main control machine analyzes the image, first converts the red-green-blue image to a grayscale image, smooths the noise, extracts the cutting edge profile, compares the standard template to identify width changes or gaps, and then uses a deep learning model (YOLOv5s) to detect cracks, passivation or gaps. If the gap depth is greater than 0.2mm or the cutting edge width increases by more than 5%, it is determined that the wear is excessive.

[0050] Automatic cutting tool replacement: The main control machine 7 generates a replacement instruction, records the tool sleeve 26 number (e.g. K1) and position (e.g. 3rd slot), and sends it to the control module (Beckhoff CX5130) through EtherCAT protocol. The control module triggers the micro pneumatic cylinder (SMC CDJ2B10-30-B) to retract the telescopic clamp 29, releasing the locking of the tool sleeve 26; the micro motor (Faulhaber 2224U012SR) closes the top opening and closing arc plate 31; the servo motor (Mitsubishi MR-JE-20A) drives the helical gear set (KHKSSG2-30) to rotate the tool sleeve 26 to 180 degrees, and exchanges the bottom standby cutting tool to the top; the new top arc plate is expanded to 90 degrees, the cutting tool 34 is aligned with the cutting groove 37, and the clamp 29 locks the tool sleeve. The moving slide 24 adjusts the position to ensure that the cutting tool 34 is accurately fitted with the cutting groove 37, and the cutting continues.

[0051] Lubrication management: Lubrication status monitoring probe 39 (Keyence IV2-G500CA) takes pictures of the surface of the cutting knife 34, and the images are transmitted to the main control machine 7, which analyzes the lubricating oil coverage and oil film uniformity. If the coverage is less than 80% or the oil film thickness is less than 0.1 millimeter, the main control machine sends a lubrication instruction to the control module. The control module drives the sliding block 18 to move to the top of the target cutting knife 34, and the metering suction pump (Graco D31255) extracts 0.05 to 0.1 milliliter of Mobilcut 100 lubricating oil, which is dropped onto the surface of the cutting knife through the oil droplet tube 20. The probe 39 checks again to ensure that the lubrication is up to standard.

[0052] Finished product collection and maintenance: The cut aluminum strip is wound by the receiving roller group 2, and the edge error is less than 0.05 millimeters. The worn cutting knife is stored in the slot 30 at the bottom of the knife sleeve 26, and the M6 bolts are manually removed and replaced with the cutting tool 33 after shutdown. The main control machine 7 records each replacement and lubrication operation and stores it in a SQLite database for easy traceability.

[0053] Effect: The system realizes continuous cutting, processes 500 meters of aluminum strip per hour, the cutting tool replacement time is less than 30 seconds, the lubrication operation takes 10 seconds, the production efficiency is improved by 20%, the edge quality is stable, and meets the requirements of electronic component packaging. Specific embodiment five: As Figures 1 to 14 shown below, specific experimental data is provided: The experiment was conducted in an aluminum strip processing plant using an aluminum strip shearing fine-tuning structure based on visual data, cutting an aluminum strip 500 millimeters wide into 50 millimeter wide strips for electronic component packaging materials. The experiment lasted for 72 hours, processing a total length of 10800 meters of aluminum strip, testing the performance of tool wear monitoring, automatic cutting tool replacement and lubrication management, and recording key indicators such as cutting accuracy, replacement efficiency, and lubrication effect.
