[0002] Gold and silver threads, as a commonly used decorative textile material, are widely used in the production of clothing, home textiles, embroidery, and other products. During the production and storage of gold and silver threads, their surface is prone to adhering to loose yarns, fiber debris, and other impurities from the environment. If these are not cleaned before being used for weaving, problems such as skipped threads, broken yarns, and blurred patterns will occur during the weaving process, seriously affecting the quality of the finished product.

[0003] Existing gold and silver thread cleaning equipment mostly uses a single cleaning roller structure, which removes impurities through frictional contact between the cleaning roller and the gold and silver thread. However, this method cannot be flexibly adjusted according to the degree of impurity adhesion on the surface of the gold and silver thread, resulting in incomplete cleaning and often requiring multiple cleaning cycles, leading to low efficiency. Therefore, this paper proposes to develop a gold and silver thread cleaning equipment integrating a visual inspection structure. Summary of the Invention

[0021] To keep the following description of the embodiments of this disclosure clear and concise, detailed descriptions of known functions and known components are omitted.

[0022] Please combine Figure 1-7As shown in the figure, the gold and silver thread clearing device with integrated visual inspection structure provided by this embodiment of the invention includes a device base 1, two sets of feed shafts 2, two sets of take-up shafts 3, a support frame 4, guide rollers 5, a clearing assembly (including a clearing roller 6 and a pressure roller 7), an image detection assembly 8, a pressure drive assembly 9, a belt synchronization assembly 10, and a PLC controller 11. All components work together to complete the entire process of feeding, inspecting, clearing, and taking up the gold and silver thread. The device base 1 supports all components of the device, ensuring stability during operation and preventing vibration from affecting the clearing and inspection accuracy. Multiple threaded mounting holes are pre-drilled on the top of the base to facilitate the positioning and fine-tuning of the shafts and frame. Two sets of pay-off shafts 2 are symmetrically installed on the front top of the equipment base 1. Each set of pay-off shafts 2 is equipped with a stepper pay-off motor (500W power, adjustable speed 0-500r / min) below it. The top of the pay-off shafts 2 is equipped with elastic limit buckles (not shown in the figure) to secure the spools wound with gold and silver wire, preventing axial displacement during rotation. Two sets of take-up shafts 3 are installed on the rear top of the equipment base 1, with their axes aligned with the axes of the pay-off shafts 2 on the same horizontal plane to ensure... During the transmission of gold and silver threads, the force is evenly distributed. Each take-up shaft 3 is equipped with a corresponding servo take-up motor (750W power, speed adjustable synchronously with the pay-off motor). The surface of the take-up shaft 3 is textured with anti-slip grooves to improve the stability of the gold and silver threads during take-up, preventing loosening or overlapping. The frame is constructed from welded aluminum alloy profiles and fixed to the top center of the equipment base 1 with high-strength bolts. A horizontal support rod is welded to the top of the frame for mounting components such as the guide roller 5, yarn clearing assembly, and image detection assembly 8. A pre-drilled cable routing groove (not shown in the diagram) is provided on the side wall of the frame for easy access to various motors and controls. The wiring layout of the device ensures a neat appearance and avoids wire tangling that could interfere with the operation of components. Two guide wheels 5 (a total of four) are symmetrically installed on the upper and lower sides of the support rod. The guide wheels are made of polyurethane and have arc-shaped grooves on their surfaces that match the specifications of the gold and silver wires. These grooves are used to guide and position the gold and silver wires during the feeding and take-up processes. The two upper guide wheels 5 are used to receive the gold and silver wires released by the feeding shaft 2, while the two lower guide wheels 5 are used to guide the gold and silver wires wound up by the take-up shaft 3. Through the guiding action of the guide wheels, the gold and silver wires are always kept in a straight line during transmission, preventing deviation or twisting during transmission. Existing gold and silver thread cleaning equipment mostly adopts a single cleaning roller structure, which removes impurities through frictional contact between the cleaning roller and the gold and silver thread. However, this method has the drawback of fixed cleaning force, which cannot be flexibly adjusted according to the adhesion of impurities on the surface of the gold and silver thread, resulting in incomplete cleaning and often requiring repeated cleaning. Figure 1As shown, the yarn clearing assembly is mounted on the support rod at the top of the support frame 4, located behind the guide roller 5. It includes two sets of clearing rollers 6 and two sets of pressing rollers 7. The two sets of clearing rollers 6 are arranged horizontally in parallel with a center-to-center distance of 150mm, perpendicular to the direction of gold and silver thread transmission. A rotatable pressing roller 7 is correspondingly installed above the rear side of each set of clearing rollers 6. The center-to-center distance between the pressing roller 7 and the clearing roller 6 can be adjusted by the pressing drive assembly 9 (adjustment range 5-15mm) to adapt to the clearing requirements of gold and silver threads of different diameters (0.1-2mm). The clearing roller 6 is made of stainless steel (304 stainless steel) with a ceramic coating (thickness 0.5mm) sprayed on the surface. The coating surface is finely polished (roughness Ra≤0.8μm) to ensure wear resistance during the clearing process and avoid damage to the surface coating of the gold and silver thread. The pressing roller 7 is made of silicone and cleans the yarn, debris and other impurities attached to the surface of the gold and silver thread through friction. An image detection component 8 is horizontally mounted on the top of the support frame 4, in front of the guide roller 5. An industrial camera on the image detection component 8 inspects the released gold and silver threads. During operation, the front pressure roller 7 is always in a downward pressure state (the gap between it and the clearing roller 6 is maintained at 1.2 times the diameter of the gold and silver thread), performing initial clearing of the thread. When the image detection component 8 detects that there are still many impurities on the surface of the gold and silver thread, the rear pressure roller 7 rotates downward according to control commands, reducing the gap with the clearing roller 6 (adjusted to 0.9 times the diameter of the gold and silver thread), achieving secondary enhanced clearing, ensuring thorough clearing in a single transmission without repeated operation. A pressure drive component 9 is provided on one side of the top of the support frame 4 to drive the pressure roller 7 to rotate. Figure 2As shown, the clamping drive assembly 9 includes an electric telescopic cylinder 91, a connecting ear plate 92, a U-shaped ear plate 93, a traction ear plate 94, and a connecting shaft 95. The connecting ear plate 92 is fixed to the bottom end of the electric telescopic cylinder 91 with bolts to connect the electric telescopic cylinder 91 with the U-shaped ear plate 93. The U-shaped ear plate 93 is fixed to the top of the support frame 4 with bolts to provide stable support for the electric telescopic cylinder 91. The bottom end of the connecting ear plate 92 is rotatably installed in the inner cavity of the U-shaped ear plate 93 via a pin, allowing the bottom end of the electric telescopic cylinder 91 to rotate flexibly around the pin (rotation angle range 0-90°), adapting to... The rotation trajectory of the pressure roller 7; the traction ear plate 94 is threadedly installed on the telescopic end of the electric telescopic cylinder 91, and the connecting shaft 95 is threadedly installed on the side wall of the pressure roller 7, with the traction ear plate 94 sleeved on the end of the connecting shaft 95, allowing the traction ear plate 94 to rotate around the connecting shaft 95; when the telescopic end of the electric telescopic cylinder 91 extends, the traction ear plate 94 pulls the connecting shaft 95, causing the pressure roller 7 to rotate downward, reducing the gap with the yarn clearing roller 6, and achieving yarn clamping and clearing; when the telescopic end of the electric telescopic cylinder 91 retracts, the traction ear plate 94 pushes the connecting shaft 95, causing the pressure roller 7 to rotate upward. The increased gap between the yarn clearing roller 6 and the yarn clearing roller 6 facilitates threading of gold and silver threads and equipment maintenance. The belt synchronization assembly 10 is located between the ends of the two sets of yarn clearing rollers 6 furthest from the pressure drive assembly 9, and is used to drive the two sets of yarn clearing rollers 6 to rotate synchronously in the same direction, ensuring uniformity of yarn clearing force. The belt synchronization assembly 10 mainly includes two synchronous pulleys, a synchronous belt, and a servo drive motor (300W power, adjustable speed 0-1000r / min). The two synchronous pulleys are respectively fixed to the ends of the two sets of yarn clearing rollers 6 by flat keys (coaxial with the yarn clearing rollers), and the synchronous belt is sleeved on the two synchronous pulleys, with tensioning pulleys provided on the surface of the synchronous belt. (Not shown in the figure) is used to adjust the tension of the synchronous belt to prevent it from slipping. The servo drive motor is fixed to the top of the support frame 4 through a motor bracket. The motor output is connected to the end of one set of yarn clearing rollers 6 through a coupling. During operation, the servo drive motor drives the yarn clearing rollers 6 to rotate. Through the cooperation of the synchronous pulley and the synchronous belt, it drives the other set of yarn clearing rollers 6 to rotate synchronously in the same direction (the speed is the same as the motor speed). This ensures that the two sets of yarn clearing rollers 6 maintain a uniform clearing force on the gold and silver threads, avoiding problems such as uneven force on the gold and silver threads and surface damage caused by inconsistent speeds. The PLC controller 11 (model: S7-200 SMART) is installed on the top side of the support frame 4 (close to the operator). The input of the PLC controller 11 is electrically connected to the detection camera 84 of the image detection component 8 and the encoders of each motor (used to detect speed). The output is electrically connected to the servo drive motors of the pay-off motor, take-up motor, electric telescopic cylinder 91, and belt synchronization component 10, realizing unified and coordinated control of all components of the equipment. Image detection component 8 is used to acquire images of the gold and silver thread surface in real time and identify impurities, providing signal feedback for the adjustment of the yarn clearing component; such as Figure 3 As shown, the image detection component 8 includes two sets of support angle adjustment components 81, support position adjustment components 82, two sets of adjustment sliders 83, and a detection camera 84 (an industrial high-definition camera with a resolution of 20 megapixels, a frame rate of 30fps, and equipped with a CMOS image sensor). The two sets of support angle adjustment components 81 are fixed to the top of the support frame 4 by bolts, which are used to support and fix the support position adjustment components 82 and to achieve fine adjustment of the detection angle. The support position adjustment components 82 are installed horizontally between the two sets of support angle adjustment components 81, which are used to provide an installation base for the adjustment sliders 83 and to achieve horizontal adjustment of the detection position. The two sets of adjustment sliders 83 are installed on the support position adjustment components 82, which are used to install the detection camera 84 and to achieve fine adjustment of the horizontal position of the camera. The detection camera 84 is installed at the bottom of the adjustment sliders 83, and the detection camera 84 is used to collect images of the gold and silver wires released by the wire feeding shaft 2. like Figure 4 As shown, the support angle adjustment component 81 includes a T-shaped support block 811 and an arc-shaped clamping plate 812. The T-shaped support block 811 has through holes on both sides of its bottom for fixing, allowing the bottom of the T-shaped support block 811 to be bolted to the top of the support frame 4. The arc-shaped clamping plate 812 is fixed to the top of the T-shaped support block 811 with M8 bolts, forming an arc-shaped groove between them for securing the end of the support position adjustment component 82. An adjustment boss 813 is provided in the middle of the top of the arc-shaped clamping plate 812, and a threaded hole is vertically provided in the center of the adjustment boss 813. An adjustment screw 814 is installed inside the threaded hole on the adjustment boss 813. Furthermore, the bottom end of the adjusting screw 814 passes through the threaded hole and abuts against the end of the support position adjusting member 82. An adjusting knob 815 is fixed on the top of the adjusting screw 814. The operator can turn the adjusting knob 815 to drive the adjusting screw 814 to move up and down, loosening or tightening the end of the support position adjusting member 82, so that the support position adjusting member 82 can rotate around its own axis between the two support angle adjusting members 81 (rotation angle range -30°~+30°), thereby adjusting the image acquisition angle of the detection camera 84, ensuring that the camera can be directly facing the surface of the released gold and silver wire, improving the clarity of image acquisition and the accuracy of impurity identification; like Figure 5As shown, the support position adjustment component 82 includes a support plate 821 and two sets of adjustment shafts 822. The two sets of adjustment shafts 822 are welded and fixed to both ends of the support plate 821. The adjustment shafts 822 are fitted with a clearance fit in the slots formed by the arc-shaped clamping plate 812 and the T-shaped support block 811, and can rotate flexibly around their own axis. The bottom end of the adjustment screw 814 abuts against the outer wall of the adjustment shaft 822, and the positioning and fixing of the adjustment shaft 822 is achieved by the abutting force. A guide slot 823 is laterally opened on the top of the support plate 821, and the guide slot 823 penetrates the bottom of the support plate 821. Adjustment slots 824 are laterally opened on the front and rear side walls of the support plate 821. The guide slots 823 and the adjustment slots 824 cooperate with each other to limit the installation position of the adjustment sliding component 83 and ensure its stability during lateral movement. Two sets of adjusting sliders 83 are symmetrically installed in the guide slots 823 of the support position adjusting member 82, for mounting the detection camera 84 and achieving fine adjustment of the camera's lateral position; such as Figure 6-7 As shown, the adjusting slider 83 includes a sliding member 831, two sets of adjusting members 832, and a camera mounting member 833. The two sets of adjusting members 832 are fixed to the front and rear sides of the sliding member 831 by countersunk bolts to limit the movement trajectory of the sliding member 831 and prevent it from deviating. The camera mounting member 833 is installed at the bottom of the sliding member 831 to enable the quick installation and removal of the detection camera 84. The sliding component 831 includes a limiting block 8311 and a guide slider 8312. The guide slider 8312 is integrally set at the bottom of the limiting block 8311. The size of the guide slider 8312 matches the size of the guide groove 823 and is inserted into the inner cavity of the guide groove 823, so that the sliding component 831 can move smoothly laterally along the guide groove 823. Positioning screw holes 8313 are provided on both the front and rear sides of the guide slider 8312 to facilitate the positioning and installation of the adjusting component 832. A fixing screw hole is provided in the middle of the bottom of the guide slider 8312 for installing the camera mounting component 833. The adjusting component 832 includes a blocking block 8321, a cylindrical slider 8322, and two flexible locking blocks 8323 (made of silicone). The cylindrical slider 8322 is integrally mounted on the side wall of the blocking block 8321, and the two sets of flexible locking blocks 8323 are symmetrically bonded to the side walls of the cylindrical slider 8322. When the cylindrical slider 8322 is installed into the inner cavity of the adjusting slot 824, the flexible locking blocks 8323 are in close contact with the upper and lower side walls of the inner cavity of the adjusting slot 824, and the sliding component 8322 is achieved through friction. 1. Temporary positioning; when the position needs to be adjusted, the flexible block 8323 can be pressed to release its contact with the adjusting slot 824, and the sliding member 831 can be pushed to move along the guide slot 823. After adjustment, the flexible block 8323 can be released to reposition; countersunk screw holes are provided on the opposite side of the blocking block 8321 and the cylindrical slider 8322, and the countersunk screw holes are set through the middle of the cylindrical slider 8322 to facilitate the installation of countersunk bolts between the adjusting member 832 and the sliding member 831; The camera mounting component 833 includes a rectangular bracket 8331 and a connecting screw 8332. The connecting screw 8332 is welded and fixed to the top center of the rectangular bracket 8331 and is threaded into the fixing screw hole at the bottom of the guide slider 8312. The height of the camera mounting component 833 can be adjusted by rotating the connecting screw 8332. The inner dimensions of the rectangular bracket 8331 match the outer dimensions of the detection camera 84. The detection camera 84 is inserted into the inner cavity of the rectangular bracket 8331, which facilitates the quick installation, disassembly, and maintenance of the camera. The working principle of the image detection component 8: The detection camera 84 acquires real-time images of the surface of the gold and silver wire released by the wire feeding shaft 2, and transmits the image data to the PLC controller 11 via a data cable. The PLC controller 11 has a built-in image recognition algorithm (based on machine vision technology, which can identify the outline and area of ​​impurities such as yarn and debris), and presets an impurity judgment threshold (which can be adjusted according to the processing requirements of gold and silver wire; by default, a yarn area ratio ≥5% or a yarn length ≥2mm is considered "excessive impurities"). When the impurities on the surface of the gold and silver wire are detected to be excessive, the PLC controller 11 immediately sends a control command to the pressing drive component 9, controlling the rear pressing roller 7 to press down for secondary yarn cleaning. If the detected impurities meet the standard, the rear pressing roller 7 is kept in the raised state, and only the front yarn cleaning roller 6 is used for preliminary yarn cleaning, realizing adaptive yarn cleaning control.
