Description

Technical Field

[0001] This utility model relates to the field of automated fabric inspection technology, and more specifically, to automated fabric inspection equipment based on machine vision. Background Art

[0002] Fabric inspection is one of the finishing processes in textiles. Traditional fabric inspection often involves visual inspection combined with manual inspection, which is inefficient. Automated fabric inspection equipment combines optical sensing elements with traditional fabric inspection equipment. The optical sensing elements collect the surface morphology of the fabric, and the collected information is processed by the automated detection system to determine whether there are defects on the fabric surface, such as yarn defects, weaving defects, stains, or color differences. This achieves automated fabric inspection and improves the stability and efficiency of the inspection.

[0003] Chinese patent application number CN202222054348.1 discloses a machine vision-based intelligent fabric inspection machine. This machine vision-based intelligent fabric inspection machine addresses the technical problem of residual threads on fabric affecting the inspection process, and provides a machine vision-based fabric inspection solution.

[0004] Then, referring to the attached diagram in its instruction manual, it can be seen that after the fabric inspection machine has completed the inspection, the equipment needs to be stopped before the fabric roll can be removed manually, which affects the efficiency of the inspection and use, makes it inconvenient to use continuously, and affects work efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automated fabric inspection device based on machine vision to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automated fabric inspection device based on machine vision, comprising a frame, a supplementary light plate on the top of the frame, a detection device on the top of the supplementary light plate, cameras symmetrically arranged on both sides of the top of the frame, a roller brush on one side of the detection device, a collection frame between the detection device and the roller brush, a collection drawer in the middle of the collection frame, a scraper fixedly connected to one end of the collection frame, and an air pipe at the bottom of the collection frame;

[0007] As can be seen, the supplementary lighting plate facilitates the detection device and camera to inspect the passing fabric, and the roller brush can sweep the top of the passing fabric to improve the cleanliness of the fabric surface and prevent threads and dust from falling on the fabric, which would affect the detection effect. The scraper can scrape off the threads on the roller brush surface and collect them in the middle of the collection drawer, improving the efficiency. The air tube blows air onto the fabric to clean it, which can blow away the threads and residual dust to avoid affecting the detection results and improve the efficiency.

[0008] The frame has rotating plates symmetrically arranged at both ends on one side. The opposite sides of the two rotating plates are rotatably connected to the wall of the frame through rotating shafts. A stepper motor is connected to one end of the rotating shaft of the rotating plate.

[0009] As can be seen, the rotating plate can support the take-up roller, and the rotating plate can be controlled to rotate by the rotating shaft by starting the stepper motor, thereby improving the performance.

[0010] The rotating plate is symmetrically provided with clamping and limiting mechanisms on both sides, and a drive motor is provided on one side of the stepper motor. The output end of the drive motor is connected to a drive gear.

[0011] As can be seen, the clamping and limiting mechanism can clamp and fix the take-up roller and limit its position. The drive motor controls the rotation of the drive gear, which facilitates the sequential control of the take-up rollers to be used, making it convenient to use and improving the performance.

[0012] Preferably, the fill light plate is located at the bottom of the fabric, the camera is horizontal with the fabric, and the detection device, collection frame, air pipe, and roller brush are all located at the top of the fabric.

[0013] It can be seen that the supplementary lighting plate can illuminate the bottom of the fabric, improving the detection effect of the camera and detection device.

[0014] Preferably, the scraper is adapted to the roller brush, the wall of the roller brush is in contact with the fabric, one end of the air pipe is connected to an air pump, and there are multiple detection devices, each corresponding to a fill light plate.

[0015] As can be seen, the scraper and roller brush can remove the brush bristles from the surface of the roller brush, and the roller brush can clean the brush bristles attached to the fabric surface. The air pump can be activated to blow air onto the fabric surface through the air pipe to clean it, thus improving the usage effect. The detection device can also improve the detection effect.

[0016] Preferably, the clamping and limiting mechanism includes two clamping plates symmetrically arranged on both sides of the rotating plate, the opposite side wall of the two clamping plates is set as an arc structure, the two clamping plates are respectively arranged on both sides of the winding roller, threaded rods are symmetrically opened at both ends of the top of the rotating plate, and limiting grooves are symmetrically opened on both sides of the rotating plate.

[0017] As can be seen, the take-up roller can be fixed by clamping it with the set clamps.

[0018] Preferably, one end of the clamping plate is fixedly connected to a limiting slider, the limiting slider is adapted to the limiting slide groove, the limiting slider is disposed in the middle of the limiting slide groove, the two ends of the threaded rod have symmetrical threads, the threaded rod passes through the middle of the limiting slide groove and the limiting slider and is threadedly connected to the wall of the limiting slider, and a rotating disk is fixedly connected to the top of the threaded rod.

[0019] As can be seen, rotating the rotating disc can control the rotation of the threaded rod, thereby causing the limiting slider to move up and down inside the limiting groove, which in turn drives the clamping plate to move, making it easier to place and remove the winding roller and improving the usage effect.

[0020] Preferably, a gear is fixedly connected to one end of the take-up roller near the stepper motor, the gear meshes with the drive gear, a sliding groove is provided on the wall of the frame at a position corresponding to the gear, and bearings are provided on both ends of the take-up roller, with the bearings corresponding to the clamping plates;

[0021] As can be seen, by meshing the gear at one end of the take-up roller with the drive gear, the drive motor can be started to control the rotation of the drive gear, which can rotate the gear to achieve the take-up of the fabric and improve the performance.

[0022] The technical effects and advantages of this utility model are:

[0023] 1. This utility model first controls the limiting slider to slide inside the limiting groove by rotating the rotating disk, thereby driving the clamping plate to open, which facilitates the loading and unloading of the take-up roller. The bearings at both ends of the take-up roller correspond to the clamping plate, so that the rotation of the take-up roller is not affected. When the gear meshes with the drive gear, the drive motor can control the corresponding take-up roller to rotate, and the stepper motor can control the rotating plate to drive the take-up roller to rotate. The positions of the two take-up rollers can be changed to facilitate continuous winding without stopping the equipment, thus improving work efficiency.

[0024] 2. This utility model also cleans the attached lint or dust on the bottom fabric surface by activating the roller brush, and scrapes off the residual lint on the roller brush by the scraper, which falls into the middle of the collection drawer for collection. By activating the air pump to inject gas into the air pipe, the lint or dust on the fabric surface can be blown up, which is convenient for detection devices and cameras to detect, and improves the accuracy of detection and the effect of use. By activating the supplementary light plate, supplementary light can be achieved, which further improves the detection effect.

[0025] In summary, through the interaction of the above-mentioned multiple functions, it is convenient to continuously feed the take-up roller without stopping the equipment, which is convenient to use, improves work efficiency, and enhances the accuracy of detection. Attached Figure Description

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] As attached Figure 1-5The automated fabric inspection equipment based on machine vision shown includes a frame 1, a supplementary light plate 2 on the top of the frame 1, a detection device 3 on the top of the supplementary light plate 2, cameras 4 symmetrically arranged on both sides of the top of the frame 1, a roller brush 5 on one side of the detection device 3, a collection frame 6 between the detection device 3 and the roller brush 5, a collection drawer 8 in the middle of the collection frame 6, a scraper 7 fixedly connected to one end of the collection frame 6, and an air pipe 9 at the bottom of the collection frame 6.

[0034] Rotating plates 10 are symmetrically arranged at both ends of one side of the frame 1. The opposite sides of the two rotating plates 10 are rotatably connected to the wall of the frame 1 via rotating shafts. A stepper motor 11 is connected to one end of the rotating plate 10 via a rotating shaft. Clamping and limiting mechanisms are symmetrically arranged on both sides of the rotating plate 10. A drive motor (not shown in the figure) is arranged on one side of the stepper motor 11. A drive gear (not shown in the figure) is connected to the output end of the drive motor.

[0035] As attached Figure 1 , 2 As shown in Figure 3, the supplementary lighting plate 2 is set at the bottom of the fabric, the camera 4 is horizontal with the fabric, and the detection device 3, collection frame 6, air pipe 9, and roller brush 5 are all set at the top of the fabric. The scraper 7 is adapted to the roller brush 5, and the wall of the roller brush 5 is in contact with the fabric. One end of the air pipe 9 is connected to an air pump. There are multiple detection devices 3, which correspond to the supplementary lighting plate 2. This allows the roller brush 5 to be activated to clean the attached lint or dust on the bottom surface of the fabric, and the scraper 7 to scrape off the lint remaining on the roller brush 5 and collect it in the middle of the collection drawer 8. By activating the air pump, gas is injected into the air pipe 9, which can blow up the lint or dust on the fabric surface, making it easier for the detection device 3 and camera 4 to detect. The supplementary lighting plate 2 can be activated to provide supplementary lighting and improve the detection effect.

[0036] As attached Figure 2 , 4As shown in Figure 5, the clamping and limiting mechanism includes two clamping plates 14 symmetrically arranged on both sides of the rotating plate 10. The opposite side wall of the two clamping plates 14 is set with an arc structure. The two clamping plates 14 are respectively arranged on both sides of the take-up roller 12. Threaded rods 17 are symmetrically opened at both ends of the top of the rotating plate 10. Limiting grooves 16 are symmetrically opened on both sides of the rotating plate 10. A limiting slider 15 is fixedly connected to one end of the clamping plate 14. The limiting slider 15 is adapted to the limiting groove 16 and is located in the middle of the limiting groove 16. The threads at both ends of the threaded rods 17 are symmetrical. 17 passes through the middle of the limiting slide groove 16 and the limiting slider 15 and is threadedly connected to the wall of the limiting slider 15. A rotating disk 18 is fixedly connected to the top of the threaded rod 17 so that the limiting slider 15 can be controlled to slide inside the limiting slide groove 16 by rotating the rotating disk 18, thereby driving the clamping plate 14 to open, so that the two ends of the take-up roller 12 can be placed in the middle of the clamping plate 14, and the take-up roller 12 can be moved out from the middle of the clamping plate 14, which facilitates loading and unloading. The threaded connection between the threaded rod 17 and the limiting slider 15 can achieve a self-locking effect, improving the stability of the clamping plate 14.

[0037] As attached Figure 4 As shown, a gear 13 is fixedly connected to one end of the take-up roller 12 near the stepper motor 11. The gear 13 meshes with the drive gear (not shown in the figure). A groove is provided on the wall of the frame 1 at the position corresponding to the gear 13. Bearings (not shown in the figure) are provided on both ends of the take-up roller 12. The bearings correspond to the clamping plate 14 so that the drive gear can be controlled to rotate by starting the drive motor. This can control the rotation of the corresponding gear 13, thereby driving the take-up roller 12 to rotate. By setting the bearings to correspond to the clamping plate 14, the rotation of the take-up roller 12 can be controlled without affecting the stability of the take-up roller 12, thus improving the performance.

[0038] It is worth noting that the threaded connection between the threaded rod 17 and the limiting slider 15 has self-locking properties, and a motor for controlling the rotation of the roller brush 5 is provided at one end of the roller brush 5.

[0039] The working principle of this utility model is as follows: In use, simply place the fabric as shown in the attached diagram. Figure 2 As shown, it is mounted on frame 1 and one end of the fabric is wound around the adjacent take-up roller 12;

[0040] When the drive motor is started and the winding roller 12 is rotated in sequence, the fabric can be wound up and moved. The fabric surface can be cleaned by the roller brush 5, and the impurities after cleaning can be collected by the scraper 7 and the collection drawer 8. Air is blown onto the fabric surface through the air pipe 9 to blow away the attached threads and dust. The fabric is illuminated by the supplementary light plate 2. Automatic detection is achieved through the detection device 3 and the camera 4, and the detection effect is improved.

[0041] When it is necessary to unload and load the take-up roller 12, simply start the stepper motor 11 to control the rotating plate 10 to drive the take-up roller 12 to rotate, so that the position of the taken-up roller 12 after winding is swapped with the new take-up roller 12. At this time, the gear 13 that meshes with the drive gear is the take-up roller 12 at one end of the new take-up roller 12, so that the drive motor controls the drive gear to rotate the new take-up roller 12, thereby realizing continuous fabric winding and improving the use effect.

[0042] Then, rotate the corresponding rotating disks 18 at both ends of the winding roller 12 after winding, and control the corresponding clamps 14 to release their grip on the winding roller 12 in sequence. This allows the winding roller 12 to be removed and a new winding roller 12 to be placed, facilitating secondary replacement and improving the performance.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
