Description

Technical Field

[0001] The utility model relates to the technical field of sock quality inspection, and more specifically, to a sock inspection device. Background Art

[0002] As a daily necessity, socks perform the basic function of keeping warm and play a role in absorbing sweat. At the same time, they reduce the wear of shoes on the heel, toes and other parts of the foot through physical buffering to improve the comfort of the foot, making them one of the indispensable daily necessities for humans. With the continuous innovation and development of industrial technology, mechanical assembly line production has gradually replaced traditional manual labor, and more and more sock machines have been put into production.

[0003] Defect detection is a key link to ensure the quality of socks. It can not only timely detect and eliminate unqualified products to reduce the defective rate, but also help enterprises timely adjust production process parameters to avoid the occurrence of batch quality problems. The current technology is to manually stretch the socks with the naked eye, which has low detection efficiency and high labor intensity. In addition, due to the limited light intensity and the error of the naked eye, the product quality fluctuates greatly.

[0004] The Chinese patent with the application number CN201920231990.8 in the prior art discloses an inspection device for a sock knitting machine, including a frame arranged on one side of the sock machine, a workbench arranged on the frame, and a display component. The workbench is provided with a plurality of hollow insertion rods inserted into the socks at intervals along its circumference. The plurality of insertion rods penetrate the workbench and are rotatably connected to the workbench. Although this solution stretches the socks and slews them on the insertion rods, which is convenient for inspectors to observe the defects on the socks, it requires manual stretching and slewing of the socks on the insertion rods. After the socks are inspected, it also requires manual removal of the socks and transfer to the next process, with low automation, high labor intensity, high labor costs and other disadvantages. In addition, although the device can make the socks unfold for easy observation, the final judgment of whether the socks are qualified still needs to be completed manually. Manual observation is subjective, and different observers may have different judgment results for the same sock. Moreover, long-term observation is likely to cause observer fatigue and affect the accuracy of judgment.

[0005] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0058] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0059] Example 1

[0060] Existing technology requires manual stretching of the socks onto the insertion rod. After the socks are inspected, they also need to be manually removed and transferred to the next process. This results in low automation and drawbacks such as high labor intensity and high labor costs. In addition, although the equipment can unfold the socks for easier observation, the final judgment on whether the socks are qualified still needs to be done manually. Manual observation is subjective, and different observers may have different judgments on the same sock. Moreover, prolonged observation can easily lead to observer fatigue and affect the accuracy of the judgment.

[0061] Therefore, such as Figures 1-21 As shown, the applicant proposes a sock testing device, the sock testing device comprising:

[0062] Frame 2, on which a temporary platform 4 is provided;

[0063] A support rotation component 3 is provided, which is used to open and rotate the socks, and the support rotation component 3 is disposed on the frame 2;

[0064] The transfer component 1 is capable of clamping and sleeveding socks onto the support rotation component 3, and the transfer component 1 is capable of transferring the socks that have been inspected and sleeved on the support rotation component 3.

[0065] Detection module 14, the detection module 14 is used to detect defects in socks fitted on the support rotation assembly 3;

[0066] The flattening and stacking component 5, in conjunction with the transfer component 1, enables the automated stacking of socks; and the flattening and stacking component 5 can flatten the stacked socks.

[0067] The sock testing equipment described in this application comprises a frame 2, a transfer assembly 1, a support and rotation assembly 3, a testing module 14, and a flattening and stacking assembly 5, which work together and are interconnected to perform multiple functions.

[0068] 1. It can automatically clamp and mount socks onto the supporting rotating component 3. After inspection, the socks are automatically transferred. It is highly automated, avoiding the pauses and waiting in manual operation, greatly shortening the inspection cycle of a single sock and significantly improving the overall production efficiency. It also greatly reduces labor intensity and labor costs and operates stably and reliably.

[0069] 2. Equipped with a detection module 14 to detect defects in socks, this technology changes the situation where the final judgment still needs to be done manually, avoids the subjectivity of human observation, and improves the accuracy of detection.

[0070] 3. Not only can it automate the folding of socks, but it can also flatten the folded socks, further enhancing the completeness and practicality of the equipment's functions.

[0071] Specifically, such as Figure 1 and Figure 2 As shown, the transfer component 1 includes:

[0072] Clamping component 13, the clamping component 13 being capable of clamping socks;

[0073] A conveying assembly, wherein the clamping assembly 13 is mounted on the conveying assembly, and the conveying assembly is capable of driving the clamping assembly 13 to move up and down and / or left and right in the sock detection device.

[0074] Specifically, such as Figure 1 and Figure 2 As shown, the transfer assembly 1 is mounted on the frame 2.

[0075] Specifically, such as Figure 6 As shown, the clamping assembly 13 includes a first clamping part 131 and a third clamping part 133, with the first clamping part 131 disposed above the third clamping part 133.

[0076] When the transfer component 1 transfers the socks that have been inspected and are mounted on the support rotation component 3 to the temporary placement table 4, it first clamps the socks from the end near the sock tube through the third clamping part 133 and moves them upward a certain distance relative to the support rotation component 3 through the transport component. Then, it clamps the socks from the end away from the sock tube through the first clamping part 131 and transfers the inspected socks through the transport component.

[0077] This application utilizes the third clamping part 133 of the transfer component 1 to clamp the sock and move it upwards. This allows the first clamping part 131 to firmly 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.

[0078] Specifically, after the sock is put on the support rotating assembly 3, the support rotating assembly 3 can open the sock and rotate it 360°. Then the detection module 14 performs defect detection. After that, the transport assembly moves to the set position and the third clamping part 133 clamps the sock from both sides and moves it upward relative to the support rotating assembly 3 by a certain distance under the drive of the transport assembly. At this time, the sock part is separated from the support rotating assembly 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 next process under the drive of the transport assembly.

[0079] As an example of this utility model, such as Figures 4-6As shown, the conveying assembly includes a conveying X-axis 11 horizontally arranged on the frame 2. The conveying X-axis 11 includes a movable sliding seat 113. A conveying Y-axis 12 is arranged on the sliding seat 113. The conveying Y-axis 12 includes a mounting seat 123 that can slide vertically. The mounting seat 123 is used to fix the clamping assembly 13.

[0080] This setup allows for precise adjustment of the position and orientation of the clamping assembly 13 by accurately controlling the movement of the sliding seat 113 on the X-axis 11 and the mounting seat 123 on the Y-axis 12. This helps reduce errors during the handling process and ensures that the socks after defect detection can be accurately placed on the temporary platform 4. At the same time, the X-axis 11 is horizontally positioned on the frame 2, providing a stable foundation support for the entire transfer assembly 1.

[0081] As an example of this utility model, such as Figure 4 As shown, 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. The first drive assembly 111 is drivenly connected to the sliding seat 113. The sliding seat 113 is slidably disposed on the first slide rail 112.

[0082] Preferred, such as Figure 6 As shown, the sliding seat 113 includes a fixed plate 1131, and a vertical support plate 1132 is provided on one side of the fixed plate 1131. The transport Y-axis 12 is fixedly connected to the fixed 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.

[0083] As an example of this utility model, such as Figure 4 and Figure 5 As shown, the transport Y-axis 12 includes a second slide rail 122 and a second drive assembly 121. The second drive assembly 121 is fixed on 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.

[0084] This arrangement makes full use of the top space of the second slide rail 122, making the overall structure of the Y-axis conveying component 12 more compact and improving space utilization, especially in the space-constrained production environment of sock production. The layout of the mounting base 123 close to the support rotating component 3 allows the socks on the support rotating component 3 to be transferred to the transfer component 1 more conveniently and quickly, minimizing the transfer distance and time during the handling process and improving production efficiency.

[0085] As an example of this utility model, the first drive component 111 and the second drive component 121 are motors.

[0086] As an example of this utility model, such as Figure 5 As shown, the first clamping part 131 includes a third driving component 1313, a first clamping block 1311, and a second clamping block 1312. The first clamping block 1311 and the second clamping block 1312 are 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. The third driving component 1313 drives the first clamping block 1311 and the second clamping block 1312 to move closer to each other or separate.

[0087] Preferred, such as Figure 5 As shown, 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.

[0088] This setup enables automated control of the clamping action. Simultaneously, 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 do not 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 side of the end by moving slightly upwards, minimizing the impact of the socks' length or thickness on the clamping action.

[0089] As an example of this utility model, such as Figure 5 and Figure 6 As shown, the third clamping part 133 includes a fifth driving component 1333, a third gripper 1331 and a fourth gripper 1332. The third gripper 1331 and the fourth gripper 1332 are arranged opposite to each other. The fifth driving component 1333 is connected to the third gripper 1331 and the fourth gripper 1332 respectively. The fifth driving component 1333 drives the third gripper 1331 and the fourth gripper 1332 to move closer to each other or separate.

[0090] As an example of this utility model, such as Figure 5 As shown, the projections of the third gripper 1331 and the fourth gripper 1332 on the horizontal plane are arc-shaped. This arrangement enables the third gripping part 133 to apply a uniform gripping force to the sock fitted on the supporting rotating assembly 3, thereby allowing it to move upward stably.

[0091] Preferred, such as Figure 5 and Figure 6As shown, 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. This arrangement, in conjunction with the third clamping part 133, allows the sock to be transferred onto the supporting rotating assembly 3, resulting in a high degree of integration and a more compact structure.

[0092] After the sock is transferred from the knitting machine to the support rotating assembly 3, the second clamping part 132 applies a downward force from the outer periphery of the sock to make the sock cuff fit onto the support rotating assembly 3. Then the second clamping part 132 moves in the opposite direction to release. The third clamping part 133 moves upward to a designated position under the drive of the transport assembly. Then the third clamping part 133 clamps the sock cuff from the outer periphery and moves downward under the drive of the transport assembly to make the sock completely fit onto the support rotating assembly 3.

[0093] As an example of this utility model, such as Figure 5 and Figure 6 As shown, the second clamping part 132 includes a fourth driving assembly 1323, a first gripper 1321, and a second gripper 1322. The first gripper 1321 and the second gripper 1322 are arranged opposite to each other, and the projections of the first gripper 1321 and the second gripper 1322 on the horizontal plane are arc-shaped. This arrangement can cooperate with the third clamping part 133 to transfer the sock to the supporting rotating assembly 3, resulting in a high degree of integration and a more compact structure.

[0094] A flexible transition portion 13211 is provided on the inner wall surface of the first gripper 1321 and the second gripper 1322. The flexible transition portion 13211 is made of foam or rubber and other materials, which can make it make flexible contact with the sock and is not affected by the thickness of the sock, so that the overall operation is stable and reliable.

[0095] As an example of this utility model, the third drive component 1313, the fourth drive component 1323, and the fifth drive component 1333 are cylinders.

[0096] Specifically, the detection module 14 is used to detect defects in the socks fitted on the support rotation assembly 3 by acquiring image information of the socks from different perspectives.

[0097] This setup utilizes the supporting rotating component 3 to open and rotate the socks to be inspected, exposing various parts of the socks, especially the heel and cuff, to the field of view of the detection module 14. The detection module 14, positioned at different heights, acquires image information of the sock surface, particularly the heel, from different angles, thereby more comprehensively and accurately detecting defects such as holes, stains, loose threads, and uneven stitching. The specific detection method of the detection module 14 is existing technology and will not be described in detail here.

[0098] As an example of this invention, the detection module 14 is mounted on the transfer assembly 1. This arrangement facilitates adjustment of the height of the detection module 14.

[0099] As an example of this invention, the detection module 14 is mounted on the transport Y-axis 12 of the transport assembly. This arrangement facilitates adjustment of the height of the detection module 14.

[0100] More specifically, such as Figure 2 As shown, the detection module 14 is mounted on the assembly plate 124, which is fixedly disposed on one side of the mounting base 123. The assembly plate 124 is vertically arranged and has an angle α with the transport X-axis 11, where α is between 15° and 75°.

[0101] This setup allows for adjustment of the distance between the detection module 14 and the support plate 124 by moving the X-axis 11. Furthermore, the tilted design of the assembly plate 124 minimizes interference from components such as the sock knitting machine located on the other side of the supporting rotating assembly 3 when the detection module 14 acquires images, further improving detection accuracy. The height of the detection module 14 is adjusted using the Y-axis 12, enabling it to acquire surface image information of the sock heel from both the bottom and top, minimizing light source interference and thus improving the accuracy and efficiency of defect detection.

[0102] As an example of this utility model, such as Figure 9 As shown, 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. The first light source 142 and the second light source 143 are 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, which is located at the notch 1241.

[0103] 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.

[0104] Preferred, such as Figure 6As shown, the camera module 141 includes a first camera 1411 and a first drive motor 1412. The first drive 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. The first drive motor 1412 is used to adjust the tilt angle of the first camera 1411.

[0105] 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 is also stretched open. At this time, by adjusting the height and tilt angle of the first camera 1411, the sock can be inspected from all angles. 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 inspection needs. Preferably, the first drive motor 1412 is mounted on the assembly plate 124 via a limiting plate, and the specific structure of the first drive motor 1412 is existing technology.

[0106] Preferably, the central axis of the first camera 1411 is perpendicular to the drive shaft of the first drive 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.

[0107] Specifically, the supporting rotation component 3 rotates the sock tube 312 via the second drive motor 35, thereby driving the sock to rotate. At the same time, the detection module 14 acquires image information of the first part of the sock in the length direction at the first height for defect detection; then the detection module 14 acquires image information of the second part of the sock in the length direction at the second height for defect detection.

[0108] The first height and the second height are h1 and h2, respectively, where h1 > h2.

[0109] Specifically, when the detection module 14 performs defect detection at the first height, the first camera 1411 is tilted downwards, and when the detection module 14 performs defect detection at the second height, the first camera 1411 is tilted upwards.

[0110] More specifically, the tilt angle is 0~45°.

[0111] The detection module 14 can adjust its height and tilt angle to detect defects in the sock cuff and heel, thereby improving detection accuracy. It divides the sock into two parts along its length, a first part and a second part, for detection, thus reducing the impact of sock length on the detection results.

[0112] The flattening and stacking assembly 5 is mounted on the frame 2.

[0113] Specifically, the flattening and stacking assembly 5 is disposed on the side of the temporary placement platform 4.

[0114] Specifically, the flattening and stacking assembly 5 is located on the side of the temporary placement platform 4 near the supporting rotation assembly 3. This arrangement facilitates the cooperation between the flattening and stacking assembly 5 and the transfer assembly 1 to achieve automated stacking of socks.

[0115] Specifically, such as Figure 7 As shown, the flattening and stacking assembly 5 includes a pressure plate 51 and a position adjustment mechanism. The pressure plate 51 is mounted on the position adjustment mechanism, which can drive the pressure plate 51 to move up and down and / or left and right in the sock detection equipment.

[0116] The first clamping part 131 clamps the sock from the end away from the sock tube and moves the inspected sock toward a predetermined position towards the temporary placement table 4 via the conveying assembly; the first clamping part 131 clamps the sock and moves downward; when the end of the sock away from the sock tube is higher than the pressure plate 51 and the end of the sock near the sock tube is lower than the pressure plate 51, the first clamping part 131 clamps the sock and moves toward the temporary placement table 4, and the end of the sock near the sock tube is transferred onto the pressure plate 51 under the action of gravity; the pressure plate 51 moves toward the direction away from the temporary placement table 4; the first clamping part 131 releases to successively detach from the sock, and finally the pressure plate 51 moves to directly above the sock and moves downward to apply a downward force to the sock.

[0117] This setup utilizes the transfer component 1 to transport qualified socks to the temporary placement table 4, achieving automated sock transfer, improving the continuity and automation of the production process, and reducing the tediousness and errors of manual handling. The first clamping part 131 of the transfer component 1 clamps the sock from the end away from the sock tube and moves downwards. When the end of the sock away from the sock tube is higher than the pressure plate 51, and the end of the sock closer to the sock tube is lower than the pressure plate 51, the transfer component 1 moves towards the temporary placement table 4, and the end of the sock closer to the sock tube is transferred onto the pressure plate 51 under the action of gravity, which helps... Maintaining the stable shape and position of the socks prevents them from becoming disordered or tangled during transfer, laying a good foundation for subsequent placement. After the pressure plate 51 moves in the opposite direction, the transfer component 1 releases the socks, allowing them to be smoothly transferred from the transfer component 1 to the socks already placed on the temporary platform 4. The pressure plate 51 moves directly above the socks and presses down to flatten and compact them. The above actions are repeated to automate the stacking of socks, facilitating subsequent transfer operations.

[0118] As an example of this utility model, the position adjustment mechanism includes a vertically arranged translation X-axis 52 and translation Y-axis 53. The translation X-axis 52 is arranged on the base plate 54 and is located below the transport X-axis 11. The translation Y-axis 53 is arranged on the translation X-axis 52. The pressure plate 51 is arranged on the top of the translation Y-axis 53 near the temporary platform 4.

[0119] This configuration allows the pressure plate 51 to move precisely in two mutually perpendicular directions. The translation X-axis 52 enables it to move back and forth in the horizontal direction, while the translation Y-axis 53 enables it to move back and forth in the vertical direction, meeting the requirements for sock placement and flattening. The translation X-axis 52 is located below the transport X-axis 11, which makes full use of the vertical space of the equipment and avoids excessive occupation of the horizontal direction by the components, making the structure of the entire equipment more compact and leaving more space for the layout of other equipment and production operations.

[0120] Preferred, such as Figure 7 As shown, the translation X-axis 52 includes:

[0121] The third slide rail 521 is mounted on the base plate 54;

[0122] The first slider 522 is slidably connected to the third slide rail 521, and the first slider 522 is used to mount the translation Y-axis 53.

[0123] Rollers 525 are disposed at both ends of the third slide rail 521, and belts 523 are disposed on the two rollers 525, the belts 523 being fixedly connected to the first slider 522;

[0124] The fourth motor 524 drives the roller 525 to rotate, thereby causing the first slider 522 to reciprocate along the third slide rail 521.

[0125] This setup utilizes the third slide rail 521 to provide precise linear motion guidance for the first slider 522, ensuring that the first slider 522 can move stably along a predetermined path, reducing deviations and wobbling during the movement, thereby ensuring the precise positioning of the pressure plate 51 in the horizontal direction and improving the accuracy and consistency of flattening the socks.

[0126] Preferably, there are two third slide rails 521 arranged in parallel to each other, and the first sliders 522 are respectively arranged on the third slide rails 521. The two first sliders 522 are used to fix the translation Y-axis 53, and one of the first sliders 522 is fixedly connected to the belt 523.

[0127] This design allows the two slide rails to effectively limit the swaying and offset of the translation Y-axis 53 perpendicular to the direction of movement when the first slider 522 moves along the third slide rail 521. This makes the entire movement process smoother and more stable, avoiding vibrations caused by uneven force on one side, thereby improving the stability and quality of the sock flattening operation. During the sock flattening process, components such as the pressure plate 51 are also subjected to the reaction force of the socks. The dual slide rail design can distribute these loads more evenly, ensuring that the equipment can stably bear the weight of components and loads, adapting to the flattening needs of socks of different sizes and weights. It also increases the overall rigidity of the translation X-axis 52, reduces structural deformation and torsion, and ensures the stability of the installation position and movement trajectory of the translation Y-axis 53. This helps to improve the overall performance and reliability of the equipment and extend its service life.

[0128] Preferred, such as Figure 7 As shown, the two sides of the pressure plate 51 are bent upwards to form flanges, one of which is fixedly connected to the translation Y-axis 53. This design makes the edge of the pressure plate 51 no longer a sharp right angle, but has a smooth transition curve. During contact and movement with the sock, this smooth edge can prevent the sock fibers from being hooked or caught by the sharp right angle, reducing problems such as tearing and snagging caused by snagging, and ensuring the integrity and quality of the sock.

[0129] As an example of this utility model, such as Figure 3As shown, the temporary placement platform 4 includes a first rotating shaft 41, a second rotating shaft 42, and a guard plate 44. There are two guard plates 44, which are spaced apart from each other. The first rotating shaft 41 and the second rotating shaft 42 are provided at the front and rear ends of the guard plates 44, and the two guard plates 44 are connected by the first rotating shaft 41 and the second rotating shaft 42. A conveyor belt 43 is provided between the two guard plates 44. The first rotating shaft 41 and the second rotating shaft 42 are used to support the conveyor belt 43. The first rotating shaft 41 or the second rotating shaft 42 is driven by a motor to rotate.

[0130] This setup allows multiple layers of stacked socks to be laid out across the entire temporary storage table 4, thereby reducing the frequency of manual handling or transferring of socks. Alternatively, the temporary storage table 4 can be used to directly transfer socks to the subsequent processing area, making it easy to connect and integrate with other sock processing equipment, thus improving the automation and continuity of the production process.

[0131] like Figures 10-21 As shown, the supporting rotation assembly 3 includes:

[0132] A sock-stretching assembly 31 is used to stretch socks. The sock-stretching assembly 31 includes a sock-stretching tube 312 and a vertical moving member 313. A first sock-stretching member 311 is provided on the sock-stretching tube 312. The vertical moving member 313 is located inside the sock-stretching tube 312. The vertical moving member 313 is used to drive the first sock-stretching member 311 to move horizontally outward relative to the sock-stretching tube 312 to stretch the socks.

[0133] The second drive motor 35 is connected to the sock support assembly 31 and can drive the sock support assembly 31 to rotate.

[0134] Specifically, such as Figure 12 As shown, the stocking support assembly 31 further includes a stocking hem stretching assembly 314, which is disposed on the first stocking support member 311. The stocking hem stretching assembly 314 is capable of stretching the stocking hem portion.

[0135] More specifically, such as Figure 18 As shown, the outer wall surface of the first sock support member 311 is provided with a first limiting groove 3111, which is used to accommodate the sock heel stretching component 314.

[0136] Specifically, such as Figure 13 As shown, the sock heel stretching assembly 314 includes a spring plate 3143 and an output unit 3146. The output unit 3146 can drive the spring plate 3143 to move outward of the sock stretching tube 312 to stretch the heel of the sock.

[0137] This design uses the first sock stretcher 311 to move horizontally outward relative to the sock tube 312, thus stretching the sock as a whole. This ensures the sock is in a relatively flat and relaxed state, allowing all parts of the sock to be fully exposed, facilitating subsequent comprehensive defect inspection. Simultaneously, a first limiting groove 3111 is provided on the outer wall of the first sock stretcher 311 to accommodate the sock heel stretching component 314. The spring plate 3143 within this component protrudes outward away from the sock tube 312 under pressure, specifically targeting the sock heel for stretching, thereby enabling defect inspection of these two key areas. Furthermore, the distance the first sock stretcher 311 moves horizontally outward relative to the sock tube 312 is controlled by adjusting the stroke of the vertical moving component 313, thus adapting to the stretching requirements of different sock sizes. The degree of protrusion of the spring plate 3143 under pressure can be adjusted according to actual needs to accommodate the elasticity and thickness of different sock heels, making it highly versatile.

[0138] As an example of this utility model, such as Figure 13 As shown, the sock heel stretching assembly 314 further includes an inner support member 3142 and an outer support member 3141. The inner support member 3142 is fitted within the first limiting groove 3111, as shown. Figure 20 As shown, the inner support member 3142 is provided with a second limiting groove 31423, which is used to limit the assembly of the outer support member 3141. The spring sheet 3143 is connected to the upper ends of the outer support member 3141 and the inner support member 3142 respectively. The lengths of the outer support member 3141, the second limiting groove 31423, the inner support member 3142, and the first limiting groove 3111 are L1, L2, L3, and L4 respectively, where L1 < L2 < L3 < L4. The lower end of the outer support member 3141 is drivenly connected to the output unit 3146. Figure 12 As shown, the sock support assembly 31 also includes a height adjustment assembly 317, which is connected to the inner support member 3142 to adjust its height.

[0139] The inner support member 3142 is shorter than the first limiting groove 3111, allowing the height adjustment component 317 to drive the inner support member 3142 to slide up and down within the first limiting groove 3111, thus adjusting the height of the sock heel stretching component 314. This enables the heel of socks of different models and sizes to be stretched open for easy defect detection, resulting in a wide range of applications. The inner support member 3142 is assembled within the first limiting groove 3111, while the outer support member 3141 is further limited and assembled within the second limiting groove 31423 of the inner support member 3142. This ensures the relative positional stability of each component during movement, preventing misalignment or wobbling between components, guaranteeing the accuracy and consistency of the sock heel stretching action, and improving the reliability of detection. As an example of this utility model, the output unit 3146 is a cylinder.

[0140] Preferred, such as Figure 13 As shown, the height adjustment component 317 includes a third motor 3174, a second lead screw 3171, a third nut seat 3172, and a guide shaft 3173. The third motor 3174 is connected to the second lead screw 3171 in a driving connection. The third nut seat 3172 is sleeved on the second lead screw 3171 and the two are threaded together. The third nut seat 3172 is connected to the inner support member 3142 through the guide shaft 3173.

[0141] When the second lead screw 3171 is rotated by the third motor 3174, the third nut seat 3172 will make precise linear movements along the axis of the second lead screw 3171. By precisely controlling the moving distance of the third nut seat 3172, the height of the sock heel stretching assembly 314 can be adjusted to meet the fine requirements of different sock heel stretching heights, thereby improving the accuracy of defect detection. The threaded connection between the second lead screw 3171 and the third nut seat 3172 has self-locking properties. When the third motor 3174 stops rotating, the third nut seat 3172 will automatically lock under the action of the thread. Locked in its current position, it will not slide or move due to external forces or its own weight, thus ensuring the stability of the sock heel opening and facilitating the smooth progress of the defect detection process. Since the third nut seat 3172 is connected to the inner support member 3142 through the guide shaft 3173, the guide shaft 3173 provides precise guidance for the linear movement of the third nut seat 3172 and the inner support member 3142, so that they can only move in a straight line along the axis of the second lead screw 3171, avoiding the shaking or tilting of the inner support member 3142 due to movement deviation, and further improving the operational stability of the device.

[0142] As an example of this utility model, such as Figure 20 As shown, the outer support member 3141 has a first protrusion 31413 on its side, and the first protrusion 31413 has a through hole 31414. The first protrusion 31413 is slidably assembled into the second limiting groove 31423. The sock heel spreading assembly 314 also includes a post, which passes through the through hole 31414 and is fixedly connected to the side walls on both sides of the second limiting groove 31423.

[0143] This design tightly connects the outer support 3141 and the inner support 3142 together, while the insertion post effectively prevents the outer support 3141 from falling out of the second limiting groove 31423 when under stress, ensuring the integrity and stability of the sock heel spreading assembly 314 structure. When the outer support 3141 is subjected to external force during movement, it can distribute the stress to the inner support 3142, thereby avoiding excessive local stress on the outer support 3141 and causing deformation or damage, thus improving the reliability and stability of the entire sock heel spreading assembly 314.

[0144] As one of the forces applied in this utility model, such as Figure 20 and Figure 21 As shown, the tops of the outer support 3141 and the inner support 3142 are respectively provided with a first connecting hole 31412 and a second connecting hole 31422 for fixing the two ends of the spring sheet 3143. This design is simple and easy to manufacture.

[0145] Preferred, such as Figure 15 and Figure 16 As shown, the vertical moving member 313 includes a pull rod 3131 and a sleeve 3132. The sleeve 3132 is sleeved around the pull rod 3131. The sock-supporting assembly 31 also includes a first motor 316 and a first transmission member 315 connected to each other. The first transmission member 315 is connected to the sleeve 3132 and the pull rod 3131 respectively, and is used to drive the sleeve 3132 and the pull rod 3131 to move in opposite directions, thereby simultaneously applying force to the upper and lower sides of the first sock-supporting member 311 to open it up.

[0146] This setup controls the opening degree of the first sock stretcher 311 by controlling the output of the first motor 316, thus meeting the defect detection requirements of socks of different sizes and specifications, and has a wide range of applications; at the same time, it applies force evenly to the upper and lower parts of the first sock stretcher 311, avoiding the situation where the upper or lower part is unevenly stressed and the opening degree is different due to the traditional sock stretcher tool, thereby avoiding local overstretching or loosening and improving the accuracy of defect detection.

[0147] Preferred, such as Figure 16 As shown, the first transmission component 315 is located on the side of the vertical moving component 313 and includes a first lead screw 3151, a first nut seat 3152, and a second nut seat 3153. The first nut seat 3152 and the second nut seat 3153 are spaced apart from each other and sleeved on the first lead screw 3151. The first nut seat 3152 is connected to the first lead screw 3151 by a reverse thread and is connected to the sleeve 3132. The second nut seat 3153 is connected to the first lead screw 3151 by a positive thread and is connected to the pull rod 3131.

[0148] This configuration easily converts the rotational motion of the first lead screw 3151 into the linear motion of the pull rod 3131 and the sleeve 3132, meeting the requirement of the sock-stretching assembly 31 applying force to the sock from both above and below simultaneously, ensuring that the sock can be stretched stably and evenly. It reduces the number and complexity of parts, lowers the manufacturing cost and maintenance difficulty of the device, and improves the reliability and stability of the device. It should be noted that the first nut seat 3152 can also have a positive thread connected to the first lead screw 3151 and the pull rod 3131, while the second nut seat 3153 can have a negative thread connected to the first lead screw 3151 and the sleeve 3132.

[0149] Preferred, such as Figure 16 As shown, the first transmission component 315 also includes guide rods 3154. There are two guide rods 3154 located on both sides of the first lead screw 3151, which are used to ensure that the first nut seat 3152 and the second nut seat 3153 move up and down along a predetermined trajectory.

[0150] This setup provides radial constraints on the first nut seat 3152 and the second nut seat 3153 via the guide rod 3154, limiting their rotational degrees of freedom and allowing them to move linearly along the guide rod 3154 to eliminate rotational deviations, thus greatly improving the straightness and accuracy of the motion. At the same time, it can withstand some lateral forces to reduce the burden on the first lead screw 3151, enhancing the structural rigidity of the entire transmission component and making it less prone to deformation or damage when subjected to large loads or external impacts.

[0151] Preferred, such as Figure 11 and 12 As shown, the sock support assembly 31 further includes a second sock support member 318, which is arranged at intervals with the first sock support member 311 along the periphery of the sock support tube 312 and is constrained at both ends by elastic members.

[0152] This design uses elastic elements to allow the first sock stretcher 311 and the second sock stretcher 318 to expand outwards at equal intervals, thereby evenly stretching the sock and ensuring that the shape and size of the sock remain regular after stretching, thus improving the quality of sock stretching. As an example of this utility model, such as... Figure 18 As shown, the top end of the first stocking support member 311 is provided with an ear plate 3114 for limiting the assembly of the elastic member. This arrangement ensures that the surface of the first stocking support member 311 is smooth, facilitating the insertion of stockings for defect detection.

[0153] like Figure 11 As shown, there can be multiple second sock stretcher members 318 extending along the length of the sock stretcher tube 312. This arrangement increases the contact area with the sock, allowing it to stretch the sock better, while also ensuring ease of assembly.

[0154] Preferred, such as Figure 11 As shown, the outer wall surfaces of the first sock support member 311 and the second sock support member 318 are projected onto the horizontal plane in an arc shape and are on the same circumference. This arrangement allows the sock support assembly 31 to have a large contact surface with the sock, resulting in a small detection error.

[0155] Preferred, such as Figure 13 As shown, the stocking support tube 312 is provided with a strip-shaped hole 3121, which is used to assemble the first stocking support member 311. Figure 19As shown, the first stocking support member 311 has a first inclined surface 3112 and a second inclined surface 3113 respectively at both ends. The first inclined surface 3112 and the second inclined surface 3113 are located on the side of the first stocking support member 311 away from the first limiting groove 3111, as shown. Figure 15 As shown, the upper end of the pull rod 3131 is provided with an upper cone 3133, the tip of which faces downward and abuts against the first inclined surface 3112, as shown. Figure 15 As shown, a lower cone 3134 is provided on the outer periphery of the top of the sleeve 3132, and the tip of the lower cone 3134 faces upward and abuts against the second inclined surface 3113.

[0156] This design eliminates the need for traditional lateral moving parts, converting the vertical movement of the vertical moving part 313 into the horizontal movement of the first support sock part 311. This results in stable and reliable transmission and simple assembly. The second support sock part 318 also has a first inclined surface 3112 and a second inclined surface 3113 at both ends, which are used to abut against the upper cone head 3133 and the lower cone head 3134, respectively; further details will not be provided here.

[0157] Preferred, such as Figure 17 As shown, the top of the stocking support tube 312 forms a third inclined surface 3122, and the first stocking support member 311 and / or the second stocking support member 318 are positioned below the third inclined surface 3122. This arrangement causes the upper end of the stocking support tube 312 to gradually narrow, making it easier for socks to be fitted onto the stocking support assembly 31.

[0158] As an example of this utility model, such as Figure 16 As shown, the lower end of the pull rod 3131 is provided with a first guide sleeve 31311, which is fitted with the second nut seat 3153 for limiting assembly. The lower end of the sleeve 3132 is provided with a second guide sleeve 31321, which is fitted with the first nut seat 3152 for limiting assembly.

[0159] This configuration provides precise guide paths for the pull rod 3131 and sleeve 3132 respectively. Driven by the first nut seat 3152 and the second nut seat 3153, the pull rod 3131 and sleeve 3132 can only move along the specified straight line direction, ensuring the straightness and accuracy of the movement. At the same time, it enables the pull rod 3131 and sleeve 3132 to be subjected to uniform constraint force during the movement, making the movement more stable and smooth, and improving the operational stability of the entire device.

[0160] Preferred, such as Figure 10As shown, the supporting rotation assembly 3 further includes a mounting bracket 32, and the stocking support tube 312 of the stocking support assembly 31 is mounted on the mounting bracket 32 ​​via a bearing 33. The supporting rotation assembly 3 also includes a second transmission component 34, and the second drive motor 35 drives the stocking support tube 312 to rotate via the second transmission component 34.

[0161] This setup uses the sock-supporting assembly 31 to rotate the socks synchronously, allowing the sock surface to be fully displayed in front of the camera and other inspection equipment. This captures information from various parts of the sock, including the cuff, body, heel, and toe, improving the accuracy and comprehensiveness of sock defect detection. Furthermore, it ensures that the time and angle of light exposure on different parts of the sock surface are relatively uniform, facilitating the acquisition of clearer and more accurate sock images, reducing misjudgments caused by uneven lighting, and improving the reliability of the inspection. The specific structure of the second transmission component 34 is prior art and will not be described in detail here.

[0162] like Figure 12 As shown, the mounting bracket 32 ​​includes a first horizontal plate 321 and a second horizontal plate 322 arranged at intervals, as... Figure 10 As shown, the stocking support tube 312 is mounted on the first horizontal plate 321 via a bearing 33, and the second drive motor 35 is located on the side of the stocking support tube 312 and fixed on the second horizontal plate 322.

[0163] This configuration allows the stocking support tube 312 to be mounted on the first horizontal plate 321 via the bearing 33. Its weight and the force generated during operation are mainly borne by the first horizontal plate 321, while the second horizontal plate 322 provides stable support for the second drive motor 35. This makes the force on the entire mounting frame 32 more even and reasonable, reducing structural deformation or damage caused by excessive local stress and improving the overall stability of the equipment. Since there is a certain distance between the second horizontal plate 322 and the first horizontal plate 321, the vibration will be attenuated to a certain extent during transmission, thereby reducing the impact of vibration on the stocking support tube 312 and ensuring the accuracy and stability of the detection and sorting process.

[0164] Preferred, such as Figure 18 As shown, the lower end of the first stocking support 311 is provided with clearance portions 3115 on both sides, such as... Figure 17 As shown, an annular rib 3123 is provided around the periphery of the stocking support tube 312. The annular rib 3123 is used to limit the upper part of the bearing 33. This arrangement can avoid interference between the first stocking support member 311 and the assembly of the bearing 33, resulting in a more compact structure. Preferably, as Figure 12 As shown, the mounting bracket 32 ​​also includes a third horizontal plate 323, which is located on the side of the second horizontal plate 322 away from the first horizontal plate 321, and is used to fix and assemble the first motor 316.

[0165] This setup forms a multi-layered support structure, effectively reducing the shaking or deformation of the mounting frame 32 caused by motor operation, ensuring the equipment remains stable during long-term operation, and providing a reliable foundation for accurate sock sorting operations; at the same time, it distributes the forces generated by components such as the first motor 316, the second drive motor 35, and the sock support cylinder 312 onto the plate, avoiding excessive local stress and extending service life.

[0166] like Figure 12 As shown, the mounting bracket 32 ​​also includes a first vertical plate 324 and a second vertical plate 325, which provide support for the first horizontal plate 321, the second horizontal plate 322, and the third horizontal plate 323. Their specific assembly relationship is prior art and will not be described further here.

[0167] As an example of this utility model, such as Figure 14 As shown, the sock heel stretching assembly 314 further includes a push ring 3144 and a bottom ring 3145 sleeved around the sock support tube 312. The bottom ring 3145 is located below the push ring 3144. The inner walls of the push ring 3144 and the bottom ring 3145 are respectively provided with a first annular groove 31441 and a second annular groove 31451. The lower ends of the outer support member 3141 and the inner support member 3142 are respectively provided with a third protrusion 31411 and a fourth protrusion 31421. The third protrusion 31411 is limited and assembled to the first annular groove 31441, and the fourth protrusion 31421 is limited and assembled to the second annular groove 31451. The output unit 3146 is fixed on the bottom ring 3145 and drivenly connected to the push ring 3144. The bottom ring 3145 is connected to the guide shaft 3173.

[0168] This setup utilizes the push ring 3144 and bottom ring 3145 to ensure constant contact with the outer support member 3141 and inner support member 3142, stably adjusting and opening the stocking hem stretching assembly 314 without interfering with the rotation of the stocking tube 312, thus enabling the stretching and rotation of the stocking.

[0169] First, the sock to be inspected is placed on the sock support tube 312. Then, the first motor 316 moves the pull rod 3131 downward through the first transmission component 315, while the sleeve 3132 moves upward in sync, causing the first sock support component 311 and the second sock support component 318 to move away from the central axis of the sock support tube 312, thus spreading the sock open. Then, the output unit 3146 drives the outer support component 3141 to move upward relative to the inner support component 3142, causing the two ends of the spring plate 3143 to squeeze each other and protrude outward, thus spreading the sock heel. The orientation of the sock heel spreading component 314 on the circumference can be set according to the orientation of the sock in the process parameters so that it is set directly opposite the sock heel. The protrusion degree of the spring plate 3143 can be adjusted by adjusting the parameters of the output unit 3146 to adapt to different socks. If necessary, the height of the sock heel spreading component 314 can be adjusted by adjusting the height component 317 to adapt to different sizes of socks. Finally, the second drive motor 35 rotates the sock support tube 312 for defect detection.

[0170] 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.
