[0001] This invention relates to the field of fabric processing technology, and in particular to a fabric inspection device and its usage method. Background Technology

[0002] During the fabric production process, production staff need to conduct a comprehensive inspection and acceptance of the finished fabric. The traditional inspection method involves placing a large soft light on the ground, placing the fabric on top of the soft light, and illuminating different parts of the fabric in sequence. At least one staff member is assigned to each side of the fabric for manual inspection. At the same time, the staff member uses an erasable marker to mark any abnormal areas on the fabric. This method is inefficient and has high labor costs. Furthermore, the marked areas are difficult to process and find later, which brings inconvenience to the fabric inspection process. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fabric inspection device and its usage method.

The moving block has an inverted U-shaped cross-section, and a displacement roller is connected to the groove of the moving block corresponding to the slide rail position.

[0010] Preferably, the camera module includes an infrared camera and a shooting camera connected one-to-one to the protruding ends on both sides of the moving block. The shooting camera includes a color camera and a black and white camera. The moving block is connected to a threader and a variable color temperature lamp on the side where the infrared camera is located. Coordinate locators are connected to the infrared camera, the shooting camera and the threader.

[0011] Preferably, the coordinate system used by the coordinate locator is the Cartesian coordinate system.

[0012] Preferably, the threader includes a threading groove opened at the protruding end of the movable block, a retractable threading needle connected to the inner end of the threading groove, a wire harness outlet, a wire selector and a limiting hole connected inside the threading groove corresponding to the threading needle, and a positioning frame connected to the port of the threading groove, and a threading hole opened on the positioning frame corresponding to the threading needle.

[0013] Preferably, the fabric feeding assembly includes limiting rollers and guide blocks. Several sets of limiting rollers are rotatably connected to the inner wall of the chassis. The limiting rollers are all connected to the motor output end inside the chassis via a transmission chain. Guide blocks are connected to the front and rear sides of each set of rollers on the inner wall of the chassis.

[0014] Preferably, an air outlet is provided on the side wall of the guide block closest to the fabric inlet, an air pump is connected to the inner wall of the chassis, the output end of the air pump is connected to the air outlet, and a debris trough is provided inside the chassis corresponding to the air outlet.

[0015] Preferably, the fabric spreading assembly is a skid fabric spreading assembly, which includes a skid spreader, and sliding rails are connected to the skid spreaders on the front and rear inner walls of the chassis.

[0016] Preferably, the fabric stacking assembly is a roller fabric stacking assembly, which includes a speed-changing gearbox. The speed-changing gearbox is connected to the roller fabric winding device. The side wall of the speed-changing gearbox is connected to the fabric guide limiting rail corresponding to the position of the roller fabric winding device. The outer wall of the roller fabric winding device has a fabric guide limiting groove. Both ends of the roller fabric winding device are coaxially rotatably connected to roller limiting blocks.

[0017] Preferably, a method of using a fabric straightening device includes the following steps:

[0018] S1. Place the original fabric roller wrapped with the fabric onto the front wall of the machine casing, and insert the end of the fabric into the fabric guide assembly working port inside the machine casing from the fabric guide port.

During this process, the fabric is fully illuminated by a diffuser, which improves the visibility of the difference between the fabric and foreign objects, making it easier for the camera module on the detection and recording assembly to record images. The built-in CNC terminal analyzes and judges the image information, and the threader enables the non-destructive marking of foreign object areas on the fabric, improving the fabric detection efficiency. Furthermore, the CNC terminal counts the number of foreign object points on the fabric, facilitating the overall scoring of the fabric and improving the overall practicality of the device. This application further reduces the labor cost of fabric inspection and improves the accuracy of fabric inspection through an automated fabric inspection device based on point maps.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Reference Figure 1-7 A fabric inspection device includes a chassis 1, a CNC terminal 2 connected to the outer wall of the chassis 1, a fabric stacking assembly 3 connected to the inner wall of the chassis 1, a raw fabric roller 4 rotatably connected to the front end of the chassis 1, a fabric guide port 5 opened on the front wall of the chassis 1 corresponding to the raw fabric roller 4, and a fabric guide assembly 6 connected to the inner wall of the chassis 1.

[0038] The inner wall of the chassis 1 is connected to the diffused light plate 7 and the detection and recording component corresponding to the fabric movement path. The diffused light plate 7 and the detection and recording component are located on the lower and upper layers of the fabric, respectively. The detection and recording component is electrically connected to the CNC terminal 2.

[0039] The detection and recording component includes a sliding rod 9 connecting the front and rear inner walls of the chassis 1, a movable block 10 slidably connected to the output end of the sliding rod 9, and a camera module and a wire threader 11 connected to the output end of the movable block 10.

[0040] The inner wall of the chassis 1 is connected to the fabric movement path terminal of the fabric stacking component 3. Non-elastic fabric can be directly put into the skid-type fabric stacking bin for stacking. The stacking standard is to stack one layer per meter in a reciprocating manner.

[0041] When the operator rotates the connecting fabric roller 4 at the front of the machine housing 1, the fabric wrapped around the outer wall of the fabric roller 4 is manually fed into the fabric guide port 5. The fabric enters the machine housing 1 under the pull of the fabric guide assembly 6. When the fabric passes through the diffuser plate 7, the illumination light emitted by the diffuser plate 7 will directly illuminate the bottom surface where it is placed. The camera module on the detection and recording assembly takes an image of the fabric illuminated by the light and transmits the image information to the CNC terminal 2. The CNC terminal 2 converts the image information into a dot matrix image. The CNC terminal 2 compares the dot matrix image with the pre-stored images and machine learning images. If there is a discrepancy between the images, the CNC terminal 2 controls the thread threader 11 to insert a pre-made rope at the misaligned position of the fabric to achieve a non-damaging mark on the fabric. Then the fabric moves through the fabric guide assembly 6 to the working end of the fabric stacking assembly 3 and enters the stacking bin for fabric stacking operations.

[0042] This application achieves a transformation of the fabric from a roller-like state to a flat state inside the machine housing 1 through the fabric feeding assembly 3 and the fabric guiding assembly 6. During this process, the fabric is fully illuminated by the diffuser 7, improving the visibility of the difference between the fabric and foreign objects, thus meeting the basic requirements for image recording by the camera module on the detection and recording assembly. The built-in CNC terminal 2 analyzes and judges the image information, and the threader 11 enables non-destructive marking of foreign object areas on the fabric, improving the fabric detection efficiency. The CNC terminal 2 also counts the number of foreign object points on the fabric, facilitating overall fabric scoring and improving the overall practicality of the device. This application, through an automated fabric inspection device based on point maps, further reduces the labor cost of fabric inspection and improves the accuracy of fabric inspection.

[0043] In this case, the cross section of the sliding rod 9 adopts an inverted T-shaped structure, and a slide rail is opened in the middle of the sliding rod 9. The cross section of the moving block 10 adopts an inverted U-shaped structure. The groove of the moving block 10 is connected to the displacement roller 12 corresponding to the slide rail position, which improves the stability of the sliding connection between the displacement roller 12 and the slide rail, and improves the stability of the connection between the sliding rod 9 and the moving block 10.

[0044] In this case, the camera module includes an infrared camera 13 and a shooting camera 14 connected one-to-one to the protruding ends on both sides of the moving block 10. The shooting camera 14 includes a color camera and a black and white camera. The moving block 10 is connected to a threader 11 and a variable color temperature lamp 23 on the side where the infrared camera 13 is located. The infrared camera 13, the shooting camera 14 and the threader 11 are all connected to coordinate locators 15. This application takes a preliminary picture of the fabric by shooting the camera 14. When the captured image information is transmitted to the CNC terminal 2, the CNC terminal 2 performs a preliminary comparison of the image. If an abnormality is found in the image, the infrared camera 13 will then enlarge and capture the image of the fabric and transmit the image to the CNC terminal 2. By adjusting the variable color temperature lamp 23, the color temperature difference of the light shining on the fabric can be changed. The color temperature can be reduced when the fabric is white and increased when the fabric is black, thereby improving the recognition rate of the camera module during the shooting process.

[0045] In this case, the coordinate system used by the coordinate locator 15 is the Cartesian coordinate system, which introduces a height coordinate axis while having planar information, thereby improving the convenience and accuracy of the marking nozzle in marking problem points.

[0046] In this case, the threader 11 includes a thread-punching groove 16 opened at the protruding end of the movable block 10. The inner end of the thread-punching groove 16 is connected to a retractable threading needle 17. The thread-punching groove 16 is connected to a wire harness outlet 18, a thread selector 19, and a limiting hole 20 corresponding to the threading needle 17. The port of the thread-punching groove 16 is connected to a positioning frame 21, and the positioning frame 21 is opened with a threading hole 22 corresponding to the threading needle 17. The wire harness outlet 18 is controlled by a CNC terminal 2 and is responsible for conveying different colored threads. The thread selector 19 can realize the initial guidance and fixed-distance cutting of the thread. The limiting hole 20 guides the thread and improves the accuracy of the thread reaching the working end of the threading needle 17. This enables the threader 11 to have the sewing function of different colored needle threads, improves the practicality of the device, and facilitates the secondary manual inspection of the fabric after inspection by the staff.

[0047] In this case, the fabric guiding assembly 6 includes limiting rollers 24 and guide blocks 25. Several sets of limiting rollers 24 are rotatably connected to the inner wall of the housing 1. The limiting rollers 24 are all connected to the motor output end inside the housing 1 through a transmission chain. The inner wall of the housing 1 is connected to the front and rear sides of each set of rollers to improve the smoothness of the fabric movement.

[0048] In this case, an air outlet 26 is opened on the side wall of the guide block 25 closest to the fabric inlet 5. An air pump is connected to the inner wall of the housing 1. The output end of the air pump is connected to the air outlet 26. A debris groove 27 is opened inside the housing 1 corresponding to the air outlet 26. The airflow ejected from the air outlet 26 blows the material attached to the fabric surface away from the fabric, improving the clarity of the fabric during the later detection and shooting process and improving the practicality of the device.

[0049] refer to Figure 3 In this case, the fabric stacking assembly 3 adopts a skid fabric stacking assembly, which includes a skid spreader 34. The front and rear inner walls of the housing 1 are connected to sliding rails 33 corresponding to the skid spreader 34, which facilitates the collection of non-elastic fabric and improves the practicality of the device.

[0050] refer to Figure 4 In this case, the fabric stacking assembly 3 adopts a roller fabric stacking assembly, which includes a speed-changing gearbox 28. The speed-changing gearbox 28 is connected to the roller fabric winding device 29. The side wall of the speed-changing gearbox 28 is connected to the fabric guide limiting rail 32 corresponding to the position of the roller fabric winding device 29. The outer wall of the roller fabric winding device 29 is provided with a fabric guide limiting groove 30. Both ends of the roller fabric winding device 29 are coaxially rotatably connected to the roller limiting block 31. The front and rear inner walls of the machine box 1 are connected to the sliding rail 33 corresponding to the roller limiting block 31. The roller limiting block 31 is slidably connected to the sliding rail 33, which facilitates the collection of elastic fabric and improves the practicality of the device.

[0051] In this case, a method of using a fabric straightening device is characterized by comprising the following steps:

[0052] S1. Place the original fabric roller 4 with the fabric wound on it onto the front wall of the machine housing 1, and insert the end of the fabric into the working port of the fabric guide assembly 6 inside the machine housing 1 from the fabric guide port 5.

[0053] S2. Start the fabric guiding component 6 through the CNC terminal 2. The fabric guiding component 6 pulls the fabric to change its position.

[0054] S3. When the fabric passes through the diffuser plate 7, the diffuser plate 7 emits illumination light.

[0055] S4. The detection and recording component adopts a line-by-line shooting mode to capture the fabric illuminated by the light and transmits the captured image information to the CNC terminal 2.

[0056] S5. The CNC terminal 2 converts the image information into a dot matrix image. The CNC terminal 2 compares the dot matrix image with the pre-stored images and the machine learning images. If there is a discrepancy between the images, the CNC terminal 2 controls the thread punch 9 to punch in the pre-made rope at the misaligned position of the fabric.

[0057] S6. The fabric is moved from the fabric feeding assembly 6 to the working end of the fabric stacking assembly 3 and enters the stacking bin for fabric stacking.

[0058] Example 2:

[0059] In the specific operation process

[0060] Place the original fabric roller 4, which is wrapped with fabric, on the front wall of the machine housing 1, and insert the end of the fabric into the working port of the fabric guide assembly 6 inside the machine housing 1 from the fabric guide port 5.

[0061] The fabric guiding component 6 is started by the CNC terminal 2, and the fabric guiding component 6 pulls the fabric to change its position.

[0062] When the fabric passes through the diffuser plate 7, the diffuser plate 7 emits illumination light;

[0063] The camera 14 uses a line-by-line shooting mode to capture image information of the fabric illuminated by light and transmits the captured image information to the CNC terminal 2. The CNC terminal 2 converts the image into a bitmap. The CNC terminal 2 judges the image based on the preset stored image and the machine learning image. If the three are similar, it is judged to have a certain problem. The fabric guide component 6 moves the fabric a set distance, and then the infrared camera 13 takes an infrared picture of the fabric and transmits the infrared image to the CNC terminal 2. The CNC terminal 2 judges the subtle differences presented by the infrared image. Based on this information, the CNC terminal 2 sends a marking information to the threader 11. The threader 11 marks the point on the fabric. If the images taken by the infrared camera 13 and the camera 14 are both judged to have a problem, a red thread is threaded to mark it.

[0064] If there is a discrepancy between the two assessments, and the image from infrared camera 13 is normal while the image from shooting camera 14 is abnormal, a blue line is drawn; if the image from shooting camera 14 is normal while the image from infrared camera 13 is abnormal, a yellow line is drawn; if both assessments indicate fabric abnormality but a determination cannot be made, a pink line is drawn to mark the fabric. This threading process will not cause any other damage to the fabric.

[0065] During use, after receiving two types of image information, the CNC terminal 2 performs phase differentiation to form a dot matrix image. The CNC terminal 2 then compares the generated dot matrix image with the fabric sample image previously entered into the system.

[0066] Please refer to the attached sample fabric dot plot diagram and the actual fabric dot plot diagram. Figure 8 Please refer to the attached diagram for a thumbnail showing the fabric placement locations. Figure 9 .

[0067] It is obvious that there is a large deviation in the three rows of 62, 63 and 64. Based on this information, the CNC terminal 2 sends a marking information to the threader 11, and the threader 11 marks the point.

[0068] When the error position in the shown image is obvious, the dot matrix can be generated directly from the image captured by camera 14.

[0069] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
