Description

Technical Field

[0001] The utility model belongs to the technical field of textiles, and particularly relates to an online automatic detection device for silk cake defects. Background Art

[0002] Chemical fiber is a man-made fiber characterized by its lightness, durability, and ease of dyeing. These properties have led to its widespread use in daily life and light industrial production. Specifically, chemical fiber is widely used in the textile industry, making it into a variety of clothing, home textiles, and industrial products. Chemical fiber cake is a shaped product of chemical fibers, primarily made from synthetic fibers such as polyester (PET), polyamide (PA), and polypropylene (PP). During the production process, these fibers undergo stretching and cooling processes to form a filamentous finished product, which is then wound into a cake-like shape. This is why it is called chemical fiber cake. Because the chemical fiber is wound around a cylindrical paper support tube to form a round cake, the cake-like shape is formed. During the manufacturing process, various defects can occur on the cake's surface due to factors such as dust contamination and mechanical damage during the spinning process and handling.

[0003] The appearance of chemical fiber yarn cakes is a crucial aspect of yarn quality. This includes defects such as poor forming, bruises, hairiness, lint, and contamination. Traditional manual inspection relies on quality control personnel in the post-processing section to manually screen inspection records. This method is not only time-consuming and labor-intensive, but also subject to environmental and emotional fluctuations, leading to missed and false detections. Furthermore, human intervention in the production process can easily introduce new sources of contamination. With the continuous advancement of artificial intelligence, machine vision, and computer technology, the chemical fiber industry is seeking automated inspection equipment to improve inspection efficiency and accuracy. However, the existing technology lacks a highly accurate, safe, and reliable yarn cake defect detection device. Utility Model Content

DETAILED DESCRIPTION

[0028] The present invention will be described in detail below with reference to specific implementation cases. The following implementation cases will help those skilled in the art to further understand the present invention, but will not limit the present invention in any form.

[0031] The aluminum profile support frame 1.1 is mainly composed of an aluminum profile frame and an aluminum plate 1.3. The aluminum plate is installed on the periphery of the aluminum profile frame. The rack mechanism 1 serves as the main support of the automatic detection device, providing space and installation position constraints for the installation of other mechanisms to ensure that each device does not shake or tilt during operation. The rack mechanism 1 is mainly composed of an aluminum profile support frame 1.1. The aluminum profile support frame 1.1 can withstand the weight of the device and various loads during operation. This support function is particularly important for network equipment such as industrial computers and cameras, because they need a stable environment to work properly. The rack mechanism can make the various functions more compactly fixed into one, realizing centralized management of equipment. Through the rack mechanism, equipment can be centrally managed, and unified scheduling and management of equipment can be realized, thereby reducing costs and improving efficiency.

[0032] The central portion of the frame structure allows for a long corridor to accommodate the bobbin conveyor mechanism, while aluminum angles on either side can be used to lock and position the conveyor mechanism.

[0037] like Figure 4 As shown, the positioning tooling 2.4 includes a tooling base plate 2.6.1, a guide wheel adjustment block 2.6.2, a center column seat 2.6.3, a carrying handle 2.6.4, a center column 2.6.8, and a limiting guide wheel 2.6.11; the outer periphery of the tooling base plate 2.6.1 is installed with a limiting guide wheel 2.6.11 through the guide wheel adjustment block 2.6.2, and the limiting guide wheel 2.6.11 is rollably connected to the conveying roller 2.1 of the conveying mechanism 2, and carrying handles 2.6.4 for carrying the positioning tooling 2.4 are installed on both sides of the tooling base plate 2.6.1, and the center column 2.6.8 is vertically fixedly installed in the middle of the tooling base plate 2.6.1 through the center column seat 2.6.3, and the positioning component is installed on the center column 2.6.8 so as to be movable up and down.

[0038] like Figure 5As shown, the positioning assembly includes a positioning tool base plate 2.6.5, a swing arm 2.6.6, a positioning column 2.6.7, an annular upper guide plate 2.6.9 and an annular lower guide plate 2.6.10; the positioning tool base plate 2.6.5, the upper guide plate 2.6.9 and the lower guide plate 2.6.10 can be mounted on the center column 2.6.8 in a manner that they can move up and down. The upper guide plate 2.6.9 and the lower guide plate 2.6.10 are both sleeved on the outer periphery of the center column 2.6.8. The lower guide plate 2.6.10 is mounted on the tool base plate 2.6.5. Plate 2.6.9 can be concentrically rotatably disposed above the lower guide plate 2.6.10, the upper guide plate 2.6.9 is provided with a number of arc grooves, the bottom ends of the three positioning posts 2.6.7 pass through the arc grooves of the upper guide plate 2.6.9 and are fixed to one end of the swing arm 2.6.6, the other end of the swing arm 2.6.6 is fixed to the lower guide plate 2.6.10 by a hinge, the swing arm 2.6.6 is disposed between the upper guide plate 2.6.9 and the lower guide plate 2.6.10, and when the swing arm 2.6.6 moves, the positioning posts 2.6.7 move synchronously.

[0039] The second inspection station assembly includes a camera fixing seat 3.16, a line scan light source 3.17, a universal ball head seat 3.18, a light source bracket 3.19, an angle adjustment block 3.20 and a line scan camera 3.21; the line scan light source 3.17 and the line scan camera 3.21 are respectively fixed on the light source bracket 3.19 and the camera fixing seat 3.16, the light source bracket 3.19 is connected to the visual mounting bracket in the second inspection station assembly through the universal ball head seat 3.18, and the camera fixing seat 3.16 is connected to the visual mounting bracket in the second inspection station assembly through the angle adjustment block 3.20.

[0040] Conveyor Mechanism 2 conveyor lines can significantly improve item handling efficiency, especially in large-scale manufacturing environments. Automated conveyor mechanisms reduce the complexity and error rates of manual operations while accelerating production. Combined with dedicated positioning tooling, they can be adjusted to meet diverse production needs, adapting to different products and process flows. This ensures quality control at every camera imaging stage, ultimately guaranteeing the stability of the final visual light source mechanism.

[0041] The conveying mechanism is mainly composed of conveying rollers, conveying frames, and positioning fixtures. The conveying rollers need to match the base size of the bobbin positioning fixture. The conveying frame, as the mounting seat for the conveying rollers and the power motor, needs to have sufficient structural strength, and the overall length of the conveying frame needs to be able to meet the layout of two defect detection stations; the overall width of the conveying frame needs to match the overall width of the customer's production line, and the overall design length of the equipment needs to be able to be connected to the bobbin production line. The power motor, as the power source of the conveyor line, is mainly composed of a motor, a sprocket pair, and a tensioning mechanism. It plays the role of starting the conveying rollers to convey the bobbin. The conveying mechanism is also equipped with pulley feet to facilitate the movement and positioning of the conveying mechanism. Figure 3 shown.

[0042] The positioning fixture is a fixture used to fix the bobbin. The positioning fixture is as follows Figure 4 As shown, it mainly consists of a tooling base plate, a carrying handle, a limiting guide wheel, a guide wheel adjustment block, a positioning tooling base plate, a positioning column, etc. The silk cake material is the target to be detected, and the middle paper tube is the positioning component of the silk cake. Silk cakes of different specifications have different paper tube inner diameters. The circumferential diameter of the three positioning columns can be adjusted by rotating the upper guide plate, and the positioning column boss and the outer tangent point can be used to complete the positioning of the silk cake at three points and one side. The upper guide plate and the lower guide plate are concentrically rotatable, and the rotation of the upper guide plate drives the swing arm of the positioning column to move synchronously in the arc groove, and the rotational motion of the upper guide plate is converted into the radial motion of the positioning column along the center of the guide plate, thereby adapting to the positioning of silk cakes with different paper tube inner diameters, such as Figure 5 shown.

[0043] The tooling base supports the main body of the material, withstanding the weight from above and the rolling friction of the roller assembly line below. It also eliminates vibration during movement, ensuring greater stability. A carrying handle is attached to the tooling base for easy handling. One end of the center column is fixed to the tooling base, while the other end is used to mount the positioning tooling base, which primarily determines the center position of the bobbin. The limiting guide wheels limit the horizontal movement of the tooling base, reducing friction between the tooling and the side conveyor frame, converting sliding friction into rolling friction. The guide wheel adjustment block secures and adjusts the limiting guide wheels to ensure the bobbin center position meets the required trajectory during tooling movement. The positioning tooling base connects to the center column base and can be moved up and down to adjust the bobbin height. A position sensor, mounted on the conveyor frame, detects when the tooling has reached the set detection position and triggers a camera to take a photo if it has.

[0044] The camera in the visual light source mechanism 3 is used to obtain image data of the silk cake and input the image data into the industrial computer 4. The industrial computer 4 is connected to the display screen 1.2 in the frame mechanism 1. The display screen 1.2 is used to receive the image information of the silk cake surface output by the industrial computer 4 and then display the image.

[0045] The front-to-back direction of the device corresponds to the direction of bobbin transport. The front direction corresponds to the direction of bobbin input, and the rear direction corresponds to the direction of bobbin output. The visual light source mechanism, primarily composed of a camera, lens, and visual mounting bracket, is used to capture real-time images of bobbin material as it passes through the inspection device. The camera must have high measurement accuracy and a field of view that covers the width of the bobbin during production. The lens must be able to fine-tune the focal length and aperture. The camera's resolution determines the inspection accuracy of the device. The visual mounting bracket must be able to fine-tune the camera's imaging angle and distance, as well as the lens spacing. The light source provides a stable light source for the inspection device, ensuring image quality and addressing ambient light interference. It also provides illumination for equipment maintenance. The light source is primarily used to illuminate the end and circumferential surfaces of the bobbin. The light source is connected to a light source controller, which must be able to adjust the brightness of the light source. The light source is mounted on the visual mounting bracket, which allows for adjustment of the lighting distance and angle. The visual mounting bracket is constructed by using a vertical pole 3.10 and a cross-axis clamp 3.11, which is flexible to adjust and easy to install. Figure 6 ) and the second detection station component (such as Figure 7 )composition.

[0046] The first inspection station assembly is used to inspect the bobbin and its core for defects. It features ten camera capture points, using ten area array cameras. Eight cameras are positioned at 45-degree intervals around the bobbin's 360-degree horizontal circumference. The remaining two cameras are positioned diagonally above the bobbin to capture images of the bobbin's core. The inspection station assembly is equipped with seven light sources. Four fan-shaped surface light sources are symmetrically arranged vertically to ensure the bobbin can freely pass through the gaps between them. Two rectangular surface light sources are fixed adjacent to the fan-shaped light sources in the direction of bobbin movement. A central ring light source is located directly above the bobbin's core to provide a light field for the cameras on both sides.

[0047] The second inspection station assembly is used to inspect the upper and lower surfaces of the yarn cake 3.22 for defects. The second inspection station assembly is equipped with four line scan camera image capture points, located above, below, and on both sides of the yarn cake. The line scan light source is fixed using a combination of a universal ball head and a visual mounting bracket. The universal ball head allows the line scan light source to be deflected and locked at any angle. The visual mounting bracket connects the light source and the universal ball head into one unit, facilitating adjustment of the light source. The camera is fixed using a combination of an angle adjustment block and a camera mounting bracket. The angle between the camera and the yarn cake can be changed by adjusting the angle adjustment block, which is convenient and quick.

[0048] The device also includes an electrical control mechanism, which is responsible for powering the visual light source mechanism and ensuring the normal operation of all components. The electrical control mechanism usually includes a power adapter and power supply interface, providing a stable and reliable power supply for cameras, lighting equipment, etc.

[0049] An industrial computer (IC) is a specialized computer device used in industrial control and automation systems. It boasts powerful computing power and stable performance, enabling long-term, reliable operation in harsh industrial environments. It can be connected to an external display screen to facilitate the capture of images of silk cakes. Industrial cameras and optical lenses, like the lens of the human eye, focus light and convert it into an image. Light sources provide sufficient light for the camera to clearly capture surface details of the product. This process converts optical signals into electrical signals, which are then converted into digital information that computers can process.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
