Description

Technical Field

[0001] The invention belongs to the technical field of pulley processing, in particular to a high-efficiency pulley material sorting and surface treatment integrated machine. Background Art

[0002] Pulleys, a type of hub, are key components in mechanical transmission systems and are widely used in various types of machinery. Their surface quality directly affects transmission efficiency, noise levels, and service life.

[0003] Traditional pulley cleaning methods generally use simple spray cleaning, which involves spraying cleaning fluid directly onto the pulley surface through a fixed or rotating nozzle, relying on the scouring effect of the liquid to remove surface dust and some oil stains. This method has a simple structure and low cost, and is widely used in small and medium-sized processing companies. However, this cleaning method is essentially passive cleaning. The workpiece itself does not participate in active movement, and the cleaning fluid can only act on the exposed surface, making it difficult to effectively penetrate into complex structures and confined areas such as pulley grooves. At the same time, spray cleaning has extremely limited removal capabilities for firmly attached sludge, oxide scale, or metal dust residue from grinding, and can often only achieve surface decontamination, failing to meet the requirements of deep cleaning.

[0004] This primitive cleaning method has significant drawbacks. For example, due to incomplete cleaning of the wheel groove, residual impurities can become embedded in the grinding disc surface during subsequent grinding, reducing grinding efficiency, increasing tool wear, and even causing burns or localized overheating and deformation on the pulley surface, seriously affecting machining quality. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-efficiency pulley material sorting and surface treatment all-in-one machine to solve the problems raised in the background technology.

Positioning cross bars are symmetrically welded to the upper and lower inner walls of the other push-pull mounting plate. First ear plates are welded to the upper and lower outer walls of the two hollow extension tubes, and the upper and lower positioning cross bars, with their ends away from the push-pull mounting plates, are both connected through the adjacent first ear plates.

[0013] This solution preferably also includes a second three-axis assembly, which includes two Y-axis lower guide rails symmetrically arranged on one side of the pulley for loading and unloading, an X-axis lower guide rail slidably installed between the top surfaces of the two Y-axis lower guide rails, an X-axis lower slider slidably installed on the top surface of the X-axis lower guide rails, a support block fixed to the top surface of the X-axis lower slider, and a hydraulic lifting column installed on the top surface of the X-axis lower slider.

[0014] Preferably, in this solution, an extension lifting block is provided above the hydraulic lifting column, and an oil cylinder is installed on the outer wall of the extension lifting block facing the pulley, and a supporting push-pull disk is fixed to the free end of the piston rod of the oil cylinder, and a fixed disk is welded to the outer wall of one end of the cylinder body of the oil cylinder close to the supporting push-pull disk, and the diameter of the supporting push-pull disk is larger than the diameter of the fixed disk, and three first hinge notches are equidistantly provided on the outer wall of the peripheral side of the fixed disk, and three second hinge notches are equidistantly provided on the outer wall of the peripheral side of the supporting push-pull disk, and the positions of the first hinge notch and the second hinge notch are aligned.

This allows the pulley to actively rotate at a constant speed in the cleaning fluid, enhancing the liquid's ability to flush surface stains. Combined with the action of the cleaning brush and cleaning wipes that engage the outer wall, dynamic scrubbing and wiping are performed simultaneously, effectively removing oil and particulate impurities adhering to the wheel hub and belt grooves, improving initial cleanliness and ensuring subsequent polishing quality. This operating mode replaces the inefficient traditional static immersion or simple spray cleaning methods, achieving a deep cleaning effect.

[0017] By arranging cleaning brushes, cleaning wipes, and surface grinding discs on both sides of the lifting connecting plate of the first three-axis assembly, and using the same drive motor to drive the pulley to rotate, the cleaning and grinding processes share the same spindle drive, which not only simplifies the equipment structure but also realizes the efficient reuse of the power system. In addition, during the cleaning process, the scrubbing action of the cleaning brush on the belt groove can expose tiny cracks or surface defects in advance, which is equivalent to completing a "wet pre-inspection"; and in the subsequent grinding process, the further treatment of the surface grinding disc on the brushed area can more evenly remove the oxide layer, avoiding the problem of uneven grinding due to local dirt obstruction, and realizing the two-way gain of "cleaning empowers grinding, and grinding improves the cleaning effect", achieving the technical effect of process collaborative optimization.

[0021] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without one or more of these details. In other instances, certain technical features well known in the art are not described to avoid confusion with the present invention.

[0022] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0023] This embodiment provides Figures 1 to 10 The high-efficiency pulley material sorting and surface treatment integrated machine shown is characterized by comprising a pulley 1, a first three-axis assembly 3, a second three-axis assembly 4 and a machine platform 12.

[0024] In this embodiment, the pulley 1 is loaded into the cleaning liquid; the first three-axis assembly 3 is arranged above the pulley 1, and a lifting connecting plate 17 is provided at the free terminal. The lower part of the lifting connecting plate 17 is provided with an axial hole for clamping the pulley 1 and driving the drive motor 6 for driving the pulley 1. A cleaning brush 26, a cleaning wiping cotton block 27 and a surface grinding disk 7 are respectively extended and adjustably provided on both sides of the lifting connecting plate 17. When the drive motor 6 drives the pulley 1 to rotate in the cleaning liquid, the cleaning brush 26 and the cleaning wiping cotton block 27 fit and abut against the outer wall surface of the pulley 1. After the first three-axis assembly 3 drives the pulley 1 to move to the grinding area, when the first three-axis assembly 3 drives the pulley 1 and drives the pulley 1 to rotate in the grinding area through the drive motor 6, the surface grinding disk 7 fits and abuts against the outer wall of the pulley 1 for grinding.

[0025] In this embodiment, after the surface grinding disc 7 polishes the pulley 1, the first three-axis assembly 3 hoisting the pulley 1 is again placed in the cleaning liquid for rinsing and cleaned with a cleaning brush 26 and a cleaning wipe 27. The first three-axis assembly 3 then uses a visual inspection module to identify and inspect whether the pulley 1 is clean. If the visual inspection module detects that there is still debris in the belt groove of the pulley 1, it needs to be placed in the cleaning liquid again, rotated, cleaned with a cleaning brush 26 and a cleaning wipe 27, and then visually inspected until it passes the inspection. The output shaft of the drive motor 6 passes through the lifting connecting plate 17 and is fixedly connected to the drive shaft 8. The drive shaft 8 is engaged with the central axis hole of the pulley 1. When the first three-axis assembly 3 drives the driving shaft 8 of the driving motor 6 to be inserted into the central shaft hole of the pulley 1, in order to make the shaft hole of the pulley 1 and the driving shaft 8 fit more closely together to prevent them from falling off, the three clamping and expanding three-claws 36 can be used to abut against the inner ring wall 45 to clamp the pulley 1 in the reverse direction. At the same time, the Y-axis lower guide rail 31 is used to drive the X-axis lower guide rail 16 close to the driving shaft 8, so that the X-axis lower guide rail 16 drives the clamping and expanding three-claws 36 to move toward the driving shaft 8, so that the clamping and expanding three-claws 36 can clamp the pulley in the reverse direction. The pulley 1 pushes the pulley 1 to fit on the drive shaft 8. In addition, when the pulley 1 is unloaded, the clamping and expanding three-claw 36 clamps the pulley 1 in the opposite direction again. At this time, the Y-axis lower guide rail 31 drives the X-axis lower guide rail 16 to move back to the drive shaft 8, that is, the X-axis lower guide rail 16 moves backward on the Y-axis lower guide rail 31, so that the clamping and expanding three-claw 36 clamps the pulley 1 and removes it from the drive shaft 8. Then, when it rotates to the unloading area, the clamping and expanding three-claw 36 releases the clamping of the pulley 1 and the pulley 1 can be unloaded. By integrating the entire process of loading, cleaning, grinding, re-cleaning, visual inspection and unloading of the pulley 1 into the same automated system, each process link is compactly connected in space and continuously flows in time, realizing an integrated operation from the original blank to the surface-treated finished product, achieving the effect of significantly improving production efficiency, reducing labor costs and operating errors. Through the design of "the first three-axis component 3 drives the lifting and translation of the lifting connecting plate 17, and an adjustable cleaning brush 26, a cleaning wiping cotton block 27 and a surface grinding disc 7 are arranged on both sides thereof", the same robotic arm system can complete both cleaning and grinding tasks without changing tooling or transferring to different equipment, realizing multi-functional integration and efficient utilization of equipment resources, avoiding the material handling loss and beat delay caused by traditional multi-machine decentralized operations, and achieving the effect of highly integrated processes.

[0026] In this embodiment, by integrating a visual inspection module (including an industrial visual camera 53 and an analysis module in the integrated module box 52) on the first three-axis component 3, and automatically capturing images after each cleaning and judging whether the cleaning is qualified, the system has intelligent feedback and adaptive control capabilities. If it is detected that there are still debris in the belt groove, the rewashing process is automatically triggered until the standard is met, realizing a closed-loop quality control mechanism of "detection-judgment-rework", changing the subjectivity and lag of traditional reliance on manual visual inspection, and achieving the effect of high product quality consistency and low defective rate. After polishing is completed, the pulley 1 is hoisted back into the cleaning liquid for a second rinse, and wiped again with a cleaning brush 26 and a cleaning wipe cotton block 27, so that the metal debris, dust and other residues generated during the polishing process are completely removed to prevent them from adhering to the surface and affecting subsequent detection or performance, realizing a "polishing-chip cleaning" closed-loop process, solving the problem of incomplete chip cleaning after polishing in traditional processes, and achieving the effect of improving both process integrity and product cleanliness.

[0027] In this embodiment, a cleaning port 2 is provided on one side of the top surface of the machine 12 for placing the pulley 1 in the cleaning liquid. A cleaning liquid box 48 is drawable below the cleaning port 2 and located on one side of the machine 12. Specifically, the cleaning liquid box 48 contains cleaning liquid, so that when the pulley 1 is inserted into the cleaning port 2, the lower portion of the pulley 1 passes through the cleaning port 2 and is immersed in the cleaning liquid in the cleaning liquid box 48. The cleaning liquid box 48 can be withdrawn as a whole, facilitating regular replacement of the cleaning liquid or removal of settled impurities. This achieves modularity and ease of maintenance for the cleaning station, avoiding the difficulties of cleaning and changing liquids in traditional fixed cleaning tanks, and achieving a cleaning system that is easy to operate and has low maintenance costs.

[0028] In this embodiment, an inverted U-shaped bracket 13 is symmetrically mounted on the top surface of the machine 12. The first three-axis assembly 3 includes an X-axis upper guide rail 5 mounted on the top of each U-shaped bracket 13, a Y-axis upper guide rail 14 slidably mounted between the tops of the two X-axis upper guide rails 5, and a Z-axis upper hydraulic column 15 slidably connected to the Y-axis upper guide rail 14. The bottom lifting end of the Z-axis upper hydraulic column 15 is fixedly mounted to a lifting connecting plate 17. The lifting connecting plate 17 can move precisely in three dimensions, achieving efficient positioning and smooth transportation of the pulley 1 between the cleaning area, the grinding area, and the inspection area. This structure has high rigidity, effectively supporting the needs of continuous multi-station operation, avoiding shaking and offset during movement, and achieving high movement accuracy and strong operational stability.

[0029] In this embodiment, a chip removal ramp 9 is located on the other side of the top surface of the machine 12. A chip collection box 10 is located below this ramp and on the other side of the machine 12. Metal dust and debris generated during the grinding process automatically slide down the ramp into the chip collection box 10 for centralized collection, preventing debris from accumulating on the equipment surface, causing secondary contamination or affecting visual inspection accuracy. The chip collection box 10 can be regularly pulled out for cleaning, ensuring closed and easy-to-clean chip removal, resulting in a clean working environment and strong self-cleaning capabilities for the equipment.

[0030] In this embodiment, hollow extension tubes 18 are welded to both sides of the lifting link 17. A hydraulic push-pull rod 20 is installed within the inner cavity of each hollow extension tube 18. A push-pull mounting plate 23 is fixedly mounted to the free push-pull ends of the two hydraulic push-pull rods 20, away from the lifting link 17. A cleaning brush 26 and a cleaning wiper 27 are mounted on the inner wall of one push-pull mounting plate 23, while a surface grinding disc 7 is mounted on the inner wall of the other push-pull mounting plate 23. The cleaning brush 26, cleaning wiper 27, and surface grinding disc 7 can be adjusted laterally based on the outer diameter of pulleys 1 of varying specifications, enabling compatible processing of a variety of workpiece sizes. This structure achieves precise push-pull control through hydraulic drive, ensuring stable contact pressure between the tool and the workpiece surface.

[0031] In this embodiment, positioning cross bars 21 are provided between the upper and lower sides of the two push-pull mounting plates 23 and the upper and lower sides of the adjacent hollow extension tubes 18. This allows the positioning cross bars 21 to maintain linear positioning when the push-pull mounting plates 23 are pushed or pulled linearly. Second lugs 22 are welded to the upper and lower outer walls of one push-pull mounting plate 23, and a positioning cross bar 21 is welded to the inner wall of each second lug 22. Positioning cross bars 21 are symmetrically welded to the inner wall of the other push-pull mounting plate 23. First lugs 19 are welded to the upper and lower outer walls of the two hollow extension tubes 18. The ends of the two positioning cross bars 21, located away from the push-pull mounting plates 23, are connected to the adjacent first lugs 19. A removable access panel 25 is screwed onto the outer wall of each hollow extension tube 18. By removing the removable access panel 25, the hydraulic push-pull rod 20 can be inspected, installed, or removed. By installing a positioning crossbar 21 between the push-pull mounting plate 23 and the hollow extension tube 18, and integrating it with the first and second lugs 19 and 22 to achieve a through-connection, the push-pull mounting plate 23, driven by the hydraulic push-pull rod 20, moves smoothly in a straight line, avoiding overloading or jamming. This guide structure improves the linearity and repeatability of the tool mounting plate, ensuring even force distribution during cleaning and polishing, resulting in high operational consistency and extended tool life. The positioning crossbar 21 installed on the push-pull mounting plate 23 and connected to the first lug 19 not only ensures the linear motion accuracy of the tool mounting plate, but also enhances the system's vibration resistance. When the surface grinding disc 7 grinds the pulley 1 at high speed, periodic vibration will be generated. The positioning cross bar 21 serves as a rigid support rod and forms a "double guide + horizontal pull" structure with the hollow extension tube 18, which effectively suppresses the swing and resonance of the push-pull mounting plate 23, thereby indirectly improving the flatness and roughness consistency of the grinding surface, realizing the dual role of "the guide structure also serving as a vibration reduction support", and achieving the effect of stable improvement in processing quality.

[0032] In this embodiment, the outer wall of the back plate of the surface grinding disc 7, the cleaning brush 26, and the cleaning and wiping cotton pad 27 are all integrally connected with a T-shaped quick-release block 29. The inner wall of each of the two push-pull mounting plates 23 is provided with a T-shaped quick-release slot 30 for the T-shaped quick-release block 29 to slide and engage. The back of the two push-pull mounting plates 23 is threadedly connected with a locking bolt 24, which passes through the T-shaped quick-release slot 30 and is connected to the T-shaped quick-release block 29. The cooperation between the T-shaped quick-release block 29 and the T-shaped quick-release slot 30 facilitates the quick removal and quick installation of the surface grinding disc 7, the cleaning brush 26, and the cleaning and wiping cotton pad 27. The locking bolt 24 is provided to lock the T-shaped quick-release block 29 in place.

[0033] In this embodiment, the second three-axis assembly 4 includes two Y-axis lower guide rails 31 symmetrically arranged on the loading and unloading side of the pulley 1, an X-axis lower guide rail 16 slidably mounted between the top surfaces of the two Y-axis lower guide rails 31, an X-axis lower slider 32 slidably mounted on the top surface of the X-axis lower guide rail 16, a support block 33 fixed to the top surface of the X-axis lower slider 32, and a hydraulic lifting column 50 mounted on the top surface of the X-axis lower slider 32. After the pulley 1 has been surface treated, the second three-axis assembly 4 can independently perform clamping, lifting, and translation operations, achieving functional decoupling and coordinated operation with the first three-axis assembly 3.

[0034] In this embodiment, an extension block 34 is positioned above the hydraulic lifting column 50. A cylinder 35 is mounted on the outer wall of the extension block 34 facing the pulley 1. A support push-pull disc 37 is fixed to the free end of the piston rod 40 of the cylinder 35. A fixed disc 38 is welded to the outer wall of the cylinder 35 at the end closest to the support push-pull disc 37. The diameter of the support push-pull disc 37 is larger than that of the fixed disc 38. Three first hinge notches 39 are evenly spaced around the outer wall of the fixed disc 38, while three second hinge notches 42 are evenly spaced around the outer wall of the support push-pull disc 37. The first hinge notches 39 and the second hinge notches 42 are aligned. Three clamping jaws 36 can be extended outward by the piston rod 40, driving the support push-pull disc 37 backward, thereby reversely gripping the inner wall of the pulley 1. This clamping method leverages the workpiece's inherent structure to achieve stable gripping, avoiding scratches on the outer surface. It is particularly suitable for polished workpieces with a high finish, achieving reliable clamping without damaging the workpiece surface.

[0035] In this embodiment, a clamping and expanding three-claw 36 is hingedly connected to each first hinged notch 39 through a pin shaft, and each clamping and expanding three-claw 36 extends from one end of the rod body away from the fixed disk 38 and is mounted and clamped in the aligned second hinged notch 42, so that when the oil cylinder 35 drives the piston rod 40 to retract and extend to drive the support push-pull disk 37 to advance and retreat, the support push-pull disk 37 drives the three clamping and expanding three-claw 36 to contract centripetally or open in opposite directions, and the free ends of the three clamping and expanding three-claw 36 rub against the fitting inner ring wall 45 of the pulley 1 to perform the opening action, so that the clamping and expanding three-claw 36 stretches to clamp the support pulley 1 in the opposite direction, and the extending lifting block 34 can drive the pulley 1 to rotate to the unloading area. The inner wall of one end of each clamping and expanding claw 36 close to the fixed disk 38 is fixedly connected to the outer wall of the piston rod 40 through a tension spring 41, so that when the piston rod 40 pushes the supporting push-pull disk 37 forward, the distance between the free ends of the three clamping and expanding claws 36 is reduced, driving the three clamping and expanding claws 36 to contract. During the contraction process, the elastic force of the tension spring 41 ensures that the clamping and expanding claws 36 are always clamped in the second hinge notch 42 and will not disengage from the second hinge notch 42. The three tension springs 41 play a role in centripetally pulling the three clamping and expanding claws 36. When the piston rod 40 pulls the supporting push-pull disk 37 backward, the supporting push-pull disk 37 opens the three clamping and expanding claws 36, so that the three clamping and expanding claws 36 are unfolded.

[0036] In this embodiment, a supporting and fitting head 43 is integrally formed at the free end of each clamping and expanding three-claw 36 away from the oil cylinder 35 , and a rubber anti-slip pad 44 is bonded to the outer wall of each supporting and fitting head 43 , and the rubber anti-slip pad 44 fits with the fitting inner ring wall 45 .

[0037] In this embodiment, the bottom of the extension lifting block 34 has a supporting base plate 49, and the top lifting end of the hydraulic lifting column 50 is fixedly installed with the bottom surface of the supporting base plate 49 by bolts. An installation cavity 46 is opened in the middle position of the top surface of the supporting base plate 49, and a rotating motor 47 is installed in the installation cavity 46. The output shaft of the rotating motor 47 is fixedly connected to the extension lifting block 34, so that the rotating motor 47 can drive the extension lifting block 34 to rotate, so that the extension lifting block 34 can reversely clamp the support pulley 1 and drive the pulley 1 to rotate to the back side of the machine 12 for unloading.

[0038] In this embodiment, positioning rods 51 are welded to the four corners of the bottom surface of the support base plate 49. The positioning rods 51 are longitudinally inserted into the support block 33, so that when the hydraulic lifting column 50 drives the support base plate 49 and the extension lifting block 34 to rise, the four positioning rods 51 are driven to rise synchronously. By designing the positioning rods 51, the lifting and lowering of the support base plate 49 and the extension lifting block 34 are longitudinally positioned. A control panel electrical box 11 is installed at the corner of one side of the top surface of the machine 12. The control panel electrical box 11 contains a PLC for controlling the opening and closing of the above-mentioned electronic components. The inner walls of the cleaning and wiping cotton block 27 and the surface grinding disc 7 are both provided with a matching track 28 that matches the outer wall of the hub of the pulley 1, so that the cleaning, wiping and grinding of the pulley 1 are more accurate and the surface treatment efficiency is improved.

[0039] In this embodiment, the visual inspection module includes an integrated module box 52 arranged on the top side of the hydraulic column 15 on the Z axis and an industrial vision camera 53 installed on the bottom surface of the integrated module box 52. The industrial vision camera 53 is responsible for acquisition. The integrated module box 52 has an analysis module for analyzing whether the outer wall of the pulley 1 is clean and whether the polishing is qualified.

[0040] In this embodiment, the industrial vision camera 53 is facing the belt groove area of ​​the pulley 1. In order to analyze and determine whether there is residual debris or incomplete cleaning in the belt groove area of ​​the pulley 1, the industrial vision camera 53 in the visual inspection module and the analysis module in the integrated module box 52 are mainly relied upon. The specific inspection steps include: S1: Use the industrial vision camera 53 to photograph the belt groove area of ​​the pulley 1. A high-resolution industrial vision camera 53 is used to clearly capture tiny details such as fine scratches and residual dust particles.

[0041] S2: De-noise the captured image, for example, by using a filtering algorithm (such as Gaussian filtering) to reduce random noise in the image to ensure the accuracy of subsequent processing, and adjust the brightness and contrast of the image to make impurities of different materials or colors more obvious and easier to identify.

[0042] Specifically, the Gaussian filtering denoising formula (image preprocessing) is used to remove random noise during image acquisition and improve image quality. The formula is as follows:

[0043] Where, : Indicates the Gaussian kernel function at pixel coordinates The weight value at is used to weighted average neighborhood pixels.

[0044] : Indicates the offset coordinates of the current pixel relative to the center of the filter window (unit: pixel), indicating the position of a point in the image relative to the center point.

[0045] : represents the standard deviation of the Gaussian distribution and controls the smoothness of the filter. In this system, The value is set according to the fineness of the pulley surface texture (usually 1 to 2 pixels) to avoid excessive blurring that affects subsequent edge detection.

[0046] The Gaussian kernel generated by this formula is convolved with the original image to achieve smoothing of the image captured by the industrial vision camera (53) and suppress the noise caused by the reflection of the cleaning fluid or the interference of ambient light; S3: Apply edge detection algorithms (such as the Sobel operator) to highlight the surface features of the pulley's belt groove and possible foreign body boundaries.

[0047] Specifically, the Sobel edge detection operator (edge ​​enhancement) is used to highlight the pulley outline and belt groove boundary to facilitate subsequent defect location. The formula is as follows: Horizontal gradient:

[0048] Vertical gradient:

[0049] Composite gradient magnitude:

[0050] in, : The original image is at position The grayscale value is collected by an industrial vision camera (53).

[0051] : The gradient components of the image in the horizontal and vertical directions, reflecting the intensity of grayscale changes, are used to identify the outer edge of the pulley and the edge of the belt groove.

[0052] : Edge strength of a pixel. A larger value indicates that the location is more likely to be an edge (such as the wall of a belt groove or the boundary of residual debris).

[0053] By calculating the gradient amplitude of each pixel, the system can accurately extract the pulley structure contour, providing a basis for subsequent comparison with the standard template.

[0054] S4: Use image segmentation technology (such as threshold segmentation) to separate the pulley from its background and identify the specific position and shape of the belt groove.

[0055] Specifically, the threshold segmentation method is used to divide pixels into several classes by setting one or more thresholds. For binary images, the simplest form is to select a grayscale threshold , and then according to the gray value of each pixel and The comparison results are classified into categories, and the formula is as follows:

[0056] in: is the original image at position Gray value.

[0057] is the preset threshold.

[0058] It is a binary image after threshold segmentation.

[0059] This formula is suitable for situations where the contrast between the background and the target is high.

[0060] S5: Scans the pulley surface based on a pre-set standard template or machine learning model to identify deviations from the ideal state. For example, by comparing the actual profile with the standard profile, it can determine whether there are abnormal protrusions or depressions.

[0061] Specifically, the defect area determination formula (size measurement) is used to quantify the size of the residual debris and determine whether rework is required. The formula is as follows:

[0062] Among them, if , it is judged as unqualified.

[0063] : The total number of pixels in the detected defect area, representing the area of ​​residual debris or stains.

[0064] : The set of all suspected defective pixels extracted by image segmentation (such as thresholding or region growing).

[0065] : Preset qualified threshold (unit: pixel 2 ), set according to the pulley specifications and process requirements. For example, the maximum allowable residual area is 50 pixels 2 .

[0066] When the grayscale of a certain area is abnormal and the area exceeds the threshold, the system determines that it is "incomplete cleaning" and triggers the re-washing process.

[0067] S6: For certain types of impurities, texture analysis techniques (such as gray-level co-occurrence matrix (GLCM)) can be used to evaluate the changes in surface roughness to determine whether there are any uncleaned substances.

[0068] Specifically, the gray-level co-occurrence matrix (GLCM) texture analysis formula is used to determine whether the surface has residual stains or uneven polishing, based on the difference in texture roughness: Assume the gray level in the image is and Two pixels in the direction ,distance The probability of simultaneous occurrence is ,but: Contrast:

[0069] Energy

[0070] Correlation:

[0071] in, : At distance ,angle Next, grayscale value and The joint probability of adjacent occurrences. In this system, we usually take , Conduct multi-directional statistics.

[0072] : The total number of gray levels in the image (e.g. 256 for an 8-bit image).

[0073] : Grayscale value and The mean of .

[0074] : The standard deviation of the corresponding grayscale value.

[0075] C: Contrast. A larger value indicates a rougher texture. Incomplete cleaning (such as oil stains or dust accumulation) can lead to increased local contrast.

[0076] Energy: This reflects the uniformity of the texture. A clean, smooth surface has higher energy; residual debris lowers the energy value.

[0077] : Correlation, which measures the linear dependence of local grayscale. The correlation is high for normal polished surfaces and decreases for contaminated areas.

[0078] By extracting multiple GLCM features, the system constructs a "cleaning status fingerprint" and compares it with the standard sample to determine whether it meets the standards.

[0079] S7: Integrated module box 52 is equipped with an image analysis algorithm or deep learning model. These models, trained on a large number of samples, can accurately distinguish between normal wear and tear and stains or debris requiring cleaning. The location of suspected impurities is precisely measured. If the size exceeds a predetermined threshold, the area is considered unacceptable. A comprehensive score is calculated based on the aforementioned indicators. If the score falls below a certain acceptable level, an alarm is triggered, prompting the operator to reclean the pulley.

[0080] Specifically, using the comprehensive scoring model (intelligent judgment), the integrated module box 52 adopts a weighted scoring function for comprehensive judgment:

[0081] in, : Comprehensive cleanliness score, with higher values ​​indicating cleaner surfaces.

[0082] : GLCM energy, correlation, and contrast of the current image.

[0083] : Average GLCM characteristic value of the standard clean pulley sample (as a benchmark).

[0084] : Maximum defect area detected.

[0085] : Maximum allowable defect area (i.e. ).

[0086] : Weight coefficient, obtained through machine learning training, reflects the importance of each feature to cleanliness judgment. For example: .

[0087] : The passing score. If the score is lower than this, the cleaning is considered to be substandard.

[0088] The model integrates multiple image features to achieve intelligent and quantitative evaluation of the pulley surface condition and avoid misjudgment of a single indicator.

[0089] S8: The inspection results are presented to the user in an intuitive manner, such as by marking all identified problems and their severity on the screen. Based on the inspection results, the system automatically determines whether the pulley meets quality requirements. Qualified products are directly fed into the unloading process, while unqualified products are sent back to the cleaning process for further processing.

[0090] S9: The data from each test will be saved for future query and quality tracking, and can also be used to optimize production process parameters.

[0091] Specifically, data recording and tracking formula are used for quality traceability to establish the inspection file of each product. The formula is as follows:

[0092] in, : No. Inspection records of each pulley.

[0093] : Detection timestamp (year, month, day, hour, minute, second).

[0094] : The original image data (or hash value).

[0095] : Corresponding GLCM eigenvalue.

[0096] : Maximum defect area.

[0097] : Comprehensive rating.

[0098] Result n : Judgment result ("qualified" or "unqualified").

[0099] All data are stored in the PLC database of the control panel electrical box 11, supporting later query, statistical analysis and process optimization.

[0100] In this embodiment, the visual inspection module (industrial vision camera 53 and integrated module box 52) automatically determines cleanliness after each cleaning and triggers a rewash process if the workpiece fails. This design not only achieves closed-loop quality control but also indirectly monitors the wear of the cleaning brush 26 and cleaning wipe 27. For example, if multiple consecutive workpieces require multiple cleanings to pass, the system can infer that the cleaning tool has aged or failed, and then issue a replacement reminder through the control panel electrical box 11. The data feedback logic effectively constitutes an intelligent early warning function for tool life management, realizing the function of "test results reversely driving maintenance decisions," achieving the effect of equipment self-diagnosis and preventive maintenance.

[0101] How it works In this high-efficiency pulley material sorting and surface treatment all-in-one machine, the operator places the pulley 1 to be processed at a predetermined position above the machine table 12, ready to enter the cleaning process. The hydraulic column 15 on the Z axis of the first three-axis assembly 3 drives the lifting plate 17 to descend, aligning the drive shaft 8 with the central axis hole of the pulley 1. The drive motor 6 drives the drive shaft 8 to rotate and insert it into the axis hole of the pulley 1. At this time, the second three-axis assembly 4 has not yet moved, and the pulley 1 is in a suspended state. The lifting plate 17 continues to descend, allowing the pulley 1 to pass through the cleaning bayonet 2, and its bottom is immersed in the cleaning liquid in the pull-out cleaning liquid box 48 below. The drive motor 6 starts, driving the drive shaft 8 to rotate, thereby driving the pulley 1 to rotate slowly in the cleaning liquid. During the rotation, impurities such as oil, dust, etc. on the pulley surface are washed away by the liquid.

[0102] The hydraulic push-pull rod 20 pushes the push-pull mounting plate 23 inward, allowing the cleaning brush 26 and cleaning wiper 27 to fit against the outer wall of the pulley 1. As the pulley 1 continues to rotate, the cleaning brush 26 scrapes off stubborn stains, and the cleaning wiper 27 absorbs residual liquid and wipes the surface. After a certain period of rotation and wiping, the lifting plate 17 rises, lifting the pulley 1 out of the cleaning liquid, completing the first stage of cleaning.

[0103] The first three-axis assembly 3, through the coordinated movement of the X-axis guide rail 5 and the Y-axis guide rail 14, translates the pulley 1 to the preset grinding station. The push-pull mounting plate 23, driven by the hydraulic push-pull rod 20, pushes the surface grinding disc 7 against the outer edge or groove surface of the pulley 1. The drive motor 6 is restarted, driving the pulley 1 to rotate. Under the action of pressure, the surface grinding disc 7 grinds the surface of the pulley 1, removing burrs, oxide layers, and performing surface finishing. After the grinding time is completed, the surface grinding disc 7 retracts, and the first three-axis assembly 3 prepares to move the pulley 1 back to the cleaning area for a second cleaning.

[0104] The first three-axis assembly 3 moves pulley 1 back above the cleaning bayonet 2 and lowers it again to immerse it in the cleaning fluid. The drive motor 6 is then restarted to rotate pulley 1. The cleaning brush 26 and cleaning wiper 27 are activated to rinse and wipe the pulley to remove metal debris and dust generated by grinding. Once cleaning is complete, the lifting plate 17 rises to the inspection height. The industrial vision camera 53 is activated to capture high-definition images of the surface of pulley 1, particularly the belt groove area. The analysis module within the integrated module box 52 processes the images to determine whether any debris remains or areas are incompletely cleaned.

[0105] If it is determined that the surface cleaning of pulley 1 meets the standards, the unloading preparation stage will begin. If it is detected that there are still impurities remaining, the control system will automatically trigger the rewashing program, and it will be lowered into the cleaning liquid again, repeating the rotation cleaning + wiping process, and performing visual inspection again. This process can be repeated many times until the test is qualified to ensure the consistency of the final product quality.

[0106] When the cleaning and polishing processes are completed, the second three-axis assembly 4 starts to work. The Y-axis lower guide rail 31 drives the X-axis lower guide rail 16 to move horizontally, so that the support block 33, the hydraulic lifting column 50, and the extension lifting block 34 are close to the pulley 1 as a whole. The hydraulic lifting column 50 rises, so that the clamping and expanding three claws 36 are aligned with the inner ring of the pulley 1, and the cylinder 35 drives the piston rod 40 to retreat, driving the support push-pull plate 37 to move backward. The support push-pull plate 37 pushes the three clamping and expanding three claws 36 to open outward, so that the support fitting head 43 and the rubber anti-slip pad 44 at the end are close to the fitting inner ring wall 45 of the pulley 1, realizing reverse clamping and fixation.

[0107] The X-axis lower guide rail 16 drives the entire clamping mechanism to retreat, smoothly extracts the pulley 1 from the drive shaft 8, and completes the separation from the first three-axis assembly 3. The rotating motor 47 is started, and the extension lifting block 34 is driven to rotate 180° through the output shaft, and the pulley 1 is transferred from the front processing area to the unloading area on the back of the machine table 12. The four positioning rods 51 are inserted into the support block 33 to ensure a smooth rotation process and prevent deflection. The oil cylinder 35 drives the piston rod 40 forward, driving the supporting push-pull disk 37 forward, causing the clamping expansion three claws 36 to contract centripetally, loosening the clamping of the pulley 1, and the pulley 1 is placed on the unloading table or conveyor belt and removed by manual or automatic transportation.

[0108] The second three-axis assembly 4 is reset, the clamping mechanism shrinks and returns to its original position, and the hydraulic lifting column 50 descends to prepare to receive the next pulley. At the same time, the first three-axis assembly 3 also returns to its initial position, waiting for the next round of loading.

[0109] Some of the metal dust and debris generated during the grinding process is removed by the cleaning fluid, while the remainder slides down the chip removal ramp 9 into the chip collection box 10 for centralized collection. The chip collection box 10 can be regularly cleaned to keep the equipment clean. The cleaning brush 26, cleaning wipe 27, and surface grinding disc 7 all utilize a T-shaped quick-release block 29 and T-shaped quick-release slot 30, which, combined with the locking bolt 24, allows for rapid replacement. A removable access panel 25 on the hollow extension tube 18 facilitates maintenance or replacement of the internal hydraulic push-pull rod 20.
