Description

Technical Field

[0001] This utility model relates to the field of textile quality testing technology, and more specifically, to a sock defect detection device. Background Technology

[0002] As a daily necessity, socks provide basic warmth and absorb sweat. They also provide physical cushioning to reduce wear and tear on the heels and toes, improving foot comfort. They are an indispensable part of human life. With continuous innovation and development in industrial technology, automated production lines are gradually replacing traditional manual labor, and more and more sock-making machines are being put into production.

[0003] Defect detection is a crucial step in ensuring sock quality. It not only allows for the timely detection and removal of substandard products to reduce the defect rate, but also helps companies adjust production process parameters promptly to avoid batch quality problems. Current technology relies on manual stretching and visual inspection, which is inefficient and labor-intensive. To address this, Chinese Patent Application No. 201821057634.0 discloses a sock defect detection device, including a frame. An electrical control box is bolted to the left side wall of the frame. A support plate is welded to the inner wall of the right end of the frame, and a servo motor is bolted to the support plate. A gear is bolted to the output shaft of the servo motor. Several sleeves running through the frame are rotatably mounted on the frame via bearings. A template column is bolted to the upper end of each sleeve, and a gear is bolted to the lower end of the outer wall of each sleeve. Gears 2 on adjacent sleeves mesh, and gear 1 meshes with the rightmost gear 2. A mounting base is rotatably mounted on the inner wall of each sleeve via bearings. This solution has advantages such as improving testing efficiency and reducing the labor intensity of workers, but it still requires manual visual inspection, which is limited by light intensity and visual error, resulting in large fluctuations in product quality.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] The problem solved by this invention is that existing sock defect detection methods are prone to missed detections due to human fatigue, resulting in large fluctuations in product quality.

[0006] To address the aforementioned problems, this utility model provides a sock defect detection device, including a frame, on which a supporting rotation component is provided. The supporting rotation component is used to open and rotate the sock to be inspected 360° in the horizontal direction. A moving component is provided on the frame, and a detection module is provided on the upper part of the moving component. The detection module can acquire images of the sock located on the supporting rotation component at different heights for defect detection.

[0007] This setup utilizes a supporting rotating component to open and rotate the socks to be inspected, ensuring that all parts of the socks are exposed to the field of view of the detection module. Detection modules at different heights acquire image information of the sock's surface, thus avoiding missed detections due to limited viewing angles. It can more comprehensively and accurately detect defects such as holes, stains, loose threads, and uneven stitching on the socks. At the same time, the moving component allows for adjustment of the height and position of the detection module, resulting in a highly integrated and compact device.

[0008] Preferably, the moving component includes a transport X-axis horizontally arranged on the frame, the transport X-axis includes a movable sliding seat, the sliding seat is provided with a transport Y-axis, the transport Y-axis includes a mounting seat that can slide vertically, an assembly plate is fixedly arranged on one side of the mounting seat, the assembly plate is vertically arranged and there is an angle α between its plane and the line where the transport X-axis is located, and the value of α is 15°-75°.

[0009] This setup allows for adjustment of the distance between the detection module and the supporting rotating assembly by moving the X-axis. Simultaneously, the inclined mounting plate minimizes interference from components such as the sock knitting machine located on the other side of the supporting rotating assembly when acquiring images, further improving detection accuracy. Adjusting the height of the detection module using the Y-axis ensures it faces the top and bottom of the sock to acquire surface image information, minimizing interference from light sources and sock length, thereby improving the accuracy and efficiency of defect detection. Preferably, the value of α is 30°-60° or 40-50°.

[0010] Preferably, the assembly plate has a notch, and the detection module includes a first light source and a second light source located on both sides of the notch. The first light source and the second light source are elongated and extend vertically. The detection module also includes a camera module located at the notch.

[0011] This setup allows light to shine evenly onto the socks from different angles, reducing shadows and reflections caused by uneven lighting. This makes imperfections on the sock surface clearer and effectively prevents them from being obscured by areas that are too bright or too dark, thus improving the accuracy of detection. Furthermore, the camera module's location at the notch ensures that it is not obstructed by the assembly plate when capturing images of the sock surface, thereby obtaining complete and clear images of the socks and providing comprehensive and accurate data for subsequent defect detection.

[0012] Preferably, the camera module includes a first camera and a first motor. The first motor is located on the side of the mounting plate away from the supporting rotation assembly and is drivenly connected to the first camera for adjusting the tilt angle of the first camera. This configuration allows for adjusting the tilt angle of the first camera at different heights, thereby meeting the defect detection requirements of the heel of the sock.

[0013] Preferably, the central axis of the first camera is perpendicular to the drive shaft of the first motor. This configuration allows the first camera to acquire image information of the sock surface in an orthographic projection manner, effectively avoiding image distortion caused by excessively tilted shooting angles. This makes the acquired sock image more consistent with its actual shape and size, providing a reliable basis for subsequent accurate defect analysis. It also reduces local over-brightness or under-brightness caused by angle issues, making the brightness of the sock surface more uniform, which helps the camera capture subtle defects on the sock surface and improves image quality and readability.

[0014] Preferably, the frame is provided with a temporary placement platform, and the temporary placement platform and the supporting rotation assembly are respectively located at both ends near the same side of the transport X-axis. The mounting base is provided with a clamping assembly on the side near the supporting rotation assembly for transferring the socks located on the supporting rotation assembly to the temporary placement platform.

[0015] This setup allows the moving component to adjust the position of the detection module and also to transfer socks before and after detection, resulting in a highly integrated device with high space utilization and significantly reduced operating costs.

[0016] Preferably, the mounting base is provided with a clamping component on the side near the supporting rotating assembly. The clamping component includes a first clamping part and a third clamping part. The third clamping part is used to clamp the sock from one end near the sock tube and move it upward relative to the supporting rotating assembly through a conveying component. The first clamping part is used to clamp the sock from the other end and transfer the sock to the temporary placement table through the conveying component.

[0017] This setup utilizes a third clamping part to hold the sock and move it upwards, allowing the first clamping part to firmly hold the sock from the top, i.e., the end furthest from the sock cuff. This avoids the problem of the sock easily falling off during transfer due to loose clamping caused by interference from the rotating support assembly, thus replacing the manual transfer process after inspection, saving labor and ensuring stable and reliable operation.

[0018] Preferably, the first clamping part includes a third driving component and a first clamping block and a second clamping block arranged opposite to each other. The third driving component is connected to the first clamping block and the second clamping block respectively to drive them to move closer to each other or separate. A first protrusion is provided on the lower side of the end of the first clamping block, and a second protrusion is provided on the second clamping block at a position corresponding to the first protrusion.

[0019] This setup enables automated control of the clamping action. The first and second protrusions allow for a certain gap between the first and second clamping blocks, facilitating assembly and ensuring that the socks do not loosen or fall off during handling. Furthermore, the socks can be clamped by the first and second protrusions located on the lower side of the end by moving slightly upwards, minimizing the impact of the clamping action on the length or thickness of the socks.

[0020] Preferably, the clamping assembly further includes a second clamping part, which is located between the first clamping part and the third clamping part. The second clamping part includes a first jaw and a second jaw arranged opposite to each other. The projection of the first jaw and / or the second jaw on the horizontal plane is arc-shaped and the inner wall surface is provided with a transition part.

[0021] This design can work in conjunction with the third clamping part to transfer the sock to the supporting rotating component, resulting in a high degree of integration and a more compact structure. Meanwhile, the transition part can be made of materials such as foam or rubber, allowing it to make flexible contact with the sock without being affected by the thickness of the sock, ensuring stable and reliable overall operation.

[0022] Preferably, the transport X-axis includes a first slide rail and a first drive assembly. The first drive assembly is fixed to the end of the first slide rail and drivenly connected to the sliding seat. The sliding seat is slidably mounted on the first slide rail. The sliding seat includes a fixed plate, and a vertical support plate is provided on one side of the fixed plate. The transport Y-axis is fixedly connected to the fixed plate and the vertical support plate, respectively. This configuration can effectively reduce the vibration and shaking of the transport Y-axis and improve operational stability and reliability.

[0023] Preferably, the transport Y-axis includes a second slide rail and a second drive assembly. The second drive assembly is fixed to the top of the second slide rail and drivenly connected to the mounting base. The mounting base is located on the side close to the supporting rotation assembly and is slidably disposed on the second slide rail.

[0024] This setup makes full use of the top space of the second slide rail, making the overall structure of the Y-axis conveyor more compact and improving space utilization, especially in space-constrained production environments such as sock production. The layout of the mounting base close to the supporting rotating component allows the socks supporting the rotating component to be transferred to the temporary platform more conveniently and quickly.

[0025] Compared with existing technologies, the sock defect detection device of this utility model has the following beneficial effects: 1) By adjusting the height of the detection module and cooperating with the supporting rotating component, complete image information of the sock surface can be obtained, minimizing interference from light sources and sock length, thereby improving the accuracy and efficiency of defect detection; 2) Because the assembly plate is tilted, the detection module can minimize interference from components such as the sock knitting machine located on the other side of the supporting rotating component when acquiring images, further improving detection accuracy; 3) By setting the first light source and the second light source, light is evenly irradiated onto the sock from different angles, reducing shadows and reflections caused by uneven lighting, making the defects on the sock surface clearer, effectively avoiding the concealment of defects due to local over-brightness or under-brightness, and improving detection accuracy; 4) The first motor can adjust the tilt angle of the first camera to achieve all-round detection of the sock heel, further improving detection accuracy.

Detailed Implementation

[0034] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Without conflict, the technical features of the embodiments of this invention can be combined with each other.

[0035] Socks are an essential daily necessity, providing warmth and protection for the feet. Currently, automated sock production using sock machines has become the industry mainstream. However, the production process requires visual inspection to detect defects, which is labor-intensive and prone to visual fatigue, leading to missed defects. Therefore, the applicant proposes the following technical solution:

[0036] Example 1

[0037] like Figure 1-6 As shown, a sock defect detection device includes a frame 2, on which a support rotation component 3 is provided. The support rotation component 3 is used to open and rotate the sock to be inspected 360° in the horizontal direction. A moving component 1 is provided on the frame 2, and a detection module 14 is provided on the upper part of the moving component 1. The detection module 14 is capable of acquiring images of the sock located on the support rotation component 3 at different heights for defect detection.

[0038] This setup utilizes the supporting rotating component 3 to open and rotate the socks to be inspected, ensuring that all parts of the socks are exposed to the field of view of the detection module 14. The detection module 14, positioned at different heights, acquires image information of the sock's surface, thus avoiding missed detections due to limited viewing angles. This allows for more comprehensive and accurate detection of defects such as holes, stains, loose threads, and uneven stitching. Simultaneously, the moving component 1 allows for adjustment of the height and position of the detection module 14, resulting in a highly integrated and compact device. The specific detection method of the detection module 14 is existing technology and will not be described in detail here.

[0039] As an example of this utility model, the moving component 1 includes a transport X-axis 11 horizontally arranged on the frame 2. The transport X-axis 11 includes a movable sliding seat 113. A transport Y-axis 12 is arranged on the sliding seat 113. The transport Y-axis 12 includes a mounting seat 123 that can slide vertically. An assembly plate 124 is fixedly arranged on one side of the mounting seat 123. The assembly plate 124 is vertically arranged and has an included angle α with the transport X-axis 11, and the value of α is 15°-75°.

[0040] This setup allows for adjustment of the distance between the detection module 14 and the supporting rotating assembly 3 by moving the X-axis 11. Simultaneously, the inclined mounting plate 124 helps the detection module 14 minimize interference from components such as the sock knitting machine located on the other side of the supporting rotating assembly 3 when acquiring images, further improving detection accuracy. The Y-axis 12 is used to adjust the height of the detection module 14, ensuring it faces the upper and lower parts of the sock to acquire surface image information, minimizing interference from light sources and sock length, thereby improving the accuracy and efficiency of defect detection.

[0041] As an example of this utility model, the assembly plate 124 is provided with a notch 1241, and the detection module 14 includes a first light source 142 and a second light source 143 located on both sides of the notch 1241. The first light source 142 and the second light source 143 are elongated and extend in the vertical direction. The detection module 14 also includes a camera module 141 located at the notch 1241.

[0042] This setup allows light to evenly illuminate the socks from different angles, reducing shadows and reflections caused by uneven lighting. This makes imperfections on the sock surface clearer and effectively prevents them from being obscured by areas that are too bright or too dark, thus improving detection accuracy. The camera module 141, located at the notch 1241, is not obstructed by the assembly plate 124 when capturing images of the sock surface, thus obtaining complete and clear images of the socks and providing comprehensive and accurate data for subsequent defect detection. This setup makes the device structure more compact, saves space, facilitates miniaturization and portability, and also makes installation and maintenance easier.

[0043] Preferably, the camera module 141 includes a first camera 1411 and a first motor 1412. The first motor 1412 is located on the side of the mounting plate 124 away from the supporting rotation assembly 3 and is drivenly connected to the first camera 1411 for adjusting the tilt angle of the first camera 1411.

[0044] This setup allows for adjustment of the tilt angle of the first camera 1411 at different heights, thereby meeting the requirements for detecting defects at the heel of the sock. Specifically, when the sock is placed on the supporting rotating assembly 3, the heel of the sock will protrude. At this time, by adjusting the height and tilt angle of the first camera 1411, all-around detection of the heel of the sock can be achieved, further improving detection accuracy. The notch 1241 also provides a certain space for the camera module 141, allowing the first camera 1411 to flexibly adjust its shooting angle according to actual detection needs. Preferably, the first motor 1412 is mounted on the fixed plate 124 via a limiting plate, and its specific structure is existing technology.

[0045] Preferably, the central axis of the first camera 1411 is perpendicular to the drive shaft of the first motor 1412. This arrangement allows the first camera 1411 to acquire image information of the sock surface in an orthographic projection manner, effectively avoiding image distortion caused by excessively tilted shooting angles, making the acquired sock image more consistent with its actual shape and size, providing a reliable basis for subsequent accurate defect analysis; reducing local over-brightness or under-brightness caused by angle issues, making the brightness of the sock surface more uniform, helping the camera to capture subtle defects on the sock surface, improving image quality and readability; and helping to stabilize the shooting position and angle of the first camera 1411, avoiding image blurring or shaking caused by vibration, ensuring image clarity and stability.

[0046] Example 2

[0047] Existing technology typically involves manually placing socks at the inspection station and then manually removing them to transfer them to the next process, which has drawbacks such as high labor intensity and high labor costs. Therefore, the applicant has made further improvements based on Example 1:

[0048] The mounting base 123 has a clamping component 13 on the side near the support rotation assembly 3. The clamping component 13 includes a first clamping part 131 and a third clamping part 133. The third clamping part 133 is used to clamp the sock from one end near the sock tube and move it upward relative to the support rotation assembly 3 through a conveying component. The first clamping part 131 is used to clamp the sock from the other end and transfer the sock to the temporary placement table 4 through the conveying component.

[0049] This setup allows the third clamping part 133 to clamp the sock and move it upwards, so that the first clamping part 131 can tightly clamp the sock from the top of the sock, that is, from the end away from the sock tube. This avoids the problem of the sock easily falling off during the transfer process due to the interference of the supporting rotating component 3, thus replacing the manual transfer process after inspection, saving labor and ensuring stable and reliable operation.

[0050] Specifically, after the sock is placed on the supporting rotating assembly 3, the supporting rotating assembly 3 can open the sock and rotate it 360°. At the same time, the moving assembly 1 moves the detection module 14 to a set position, and the detection module 14 performs defect detection. After that, after the moving assembly 1 moves to the predetermined position, the third clamping part 133 clamps the sock from both sides and moves it upward relative to the supporting rotating assembly 3 under the drive of the transport assembly. At this time, the sock part is detached from the supporting rotating assembly 3. The first clamping part 131 clamps the sock from the top, and then the third clamping part 133 moves in the opposite direction to release the sock. Then, it is transferred to the temporary placement table 4 under the drive of the moving assembly 1. The specific structure of the supporting rotating assembly 3 is prior art and will not be described in detail here.

[0051] As an example of this utility model, the transport X-axis 11 includes a first slide rail 112 and a first drive assembly 111. The first drive assembly 111 is fixed to the end of the first slide rail 112 and drivenly connected to the sliding seat 113. The sliding seat 113 is slidably disposed on the first slide rail 112. Preferably, the sliding seat 113 includes a fixing plate 1131, and a vertical support plate 1132 is disposed on one side of the fixing plate 1131. The transport Y-axis 12 is fixedly connected to the fixing plate 1131 and the vertical support plate 1132 respectively. This arrangement can effectively reduce the vibration and shaking of the transport Y-axis 12 and improve the operational stability and reliability.

[0052] As an example of this utility model, the transport Y-axis 12 includes a second slide rail 122 and a second drive assembly 121. The second drive assembly 121 is fixed to the top of the second slide rail 122 and is drivenly connected to the mounting base 123. The mounting base 123 is located on the side close to the support rotation assembly 3 and is slidably disposed on the second slide rail 122.

[0053] This design fully utilizes the top space of the second slide rail 122, making the overall structure of the Y-axis conveying device 12 more compact and improving space utilization, especially in space-constrained production environments such as sock manufacturing. Furthermore, the placement of the mounting base 123 close to the supporting rotating assembly 3 allows the socks on the supporting rotating assembly 3 to be transferred to the temporary placement table 4 more conveniently and quickly, minimizing the transfer distance and time during handling and improving production efficiency. As an example of this invention, the first drive assembly 111 and the second drive assembly 121 are motors.

[0054] As an example of this utility model, the first clamping part 131 includes a third driving component 1313 and a first clamping block 1311 and a second clamping block 1312 arranged opposite to each other. The third driving component 1313 is connected to the first clamping block 1311 and the second clamping block 1312 respectively to drive them to move closer to each other or separate. A first protrusion 13111 is provided on the lower side of the end of the first clamping block 1311, and a second protrusion 13121 is provided on the second clamping block 1312 at a position corresponding to the first protrusion 13111.

[0055] This design enables automated control of the clamping action. The first protrusion 13111 and the second protrusion 13121 create a certain gap between the first clamping block 1311 and the second clamping block 1312, facilitating assembly and ensuring the socks won't loosen or fall off during handling. Furthermore, the socks can be clamped by the first protrusion 13111 and the second protrusion 13121 located on the lower end of the socks with only a slight upward movement, minimizing the impact of the socks' length or thickness on the clamping action. As an example of this invention, the third drive component 1313 is a cylinder.

[0056] As an example of this utility model, the third clamping part 133 is located below the first clamping part 131 and includes a third clamping claw 1331 and a fourth clamping claw 1332 arranged opposite each other. The third clamping claw 1331 and the fourth clamping claw 1332 can approach or separate each other, and their projections on the horizontal plane are arc-shaped. This arrangement allows the third clamping part 133 to apply a uniform clamping force to the sock fitted on the supporting rotating assembly 3, thereby enabling it to move upward stably. The first clamping claw 1321 and the second clamping claw 1322 are driven by a cylinder, which will not be described in detail here.

[0057] Preferably, the clamping assembly 13 further includes a second clamping part 132, which is located between the first clamping part 131 and the third clamping part 133. The second clamping part 132 includes a first gripper 1321 and a second gripper 1322 arranged opposite to each other. The projection of the first gripper 1321 and / or the second gripper 1322 on the horizontal plane is arc-shaped, and a transition part 13211 is provided on the inner wall surface. This arrangement can cooperate with the third clamping part 133 to transfer the sock to the supporting rotation assembly 3, resulting in a high degree of integration and a more compact structure. At the same time, the transition part 13211 can be made of materials such as foam or rubber, which allows it to make flexible contact with the sock and is not affected by the thickness of the sock, ensuring stable and reliable overall operation.

[0058] Specifically, after the socks are transferred from the sock-making machine to the support rotating assembly 3, the second clamping part 132 applies a downward force from the outer periphery of the socks to make the sock cuff fit onto the support rotating assembly 3. Then, the second clamping part 132 reverses its movement to release. The third clamping part 133 moves upward to a designated position under the drive of the conveying assembly. Afterward, the third clamping part 133 clamps the sock cuff from the outer periphery and then moves downward under the drive of the conveying assembly to completely fit the sock onto the support rotating assembly 3. The support rotating assembly 3 then... The sock is spread out and rotated 360°. The detection module 14 acquires image information of the outer surface of the sock for defect detection. Then, it moves to a predetermined position through the moving component 1. The third clamping part 133 clamps the sock from both sides and moves it upward relative to the supporting rotating component 3 under the drive of the transport component. At this time, the sock part is separated from the supporting rotating component 3. The first clamping part 131 clamps the sock from the top. Then, the third clamping part 133 moves in the opposite direction to release the sock. Then, it is transferred to the temporary placement table 4 under the drive of the moving component 1.

[0059] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
