Technical Field
[0001] This utility model relates to the field of fabric inspection equipment technology, and in particular to a fabric defect detection device. Background Technology
[0002] Fabric inspection machines are essential specialized equipment used in the garment industry to inspect extra-large, double-width, and single-width fabrics such as cotton, wool, linen, silk, and chemical fibers before production. Fabric inspection machines can continuously unfold the fabric and provide light sources at specific angles, allowing workers to easily detect defects in the fabric.
[0003] Traditional manual fabric inspection can detect a maximum of 200 defects per hour, and the concentration required for manual inspection is limited to 20-30 minutes. Beyond this time, visual fatigue sets in. Furthermore, the speed of manual inspection is only 5-20 meters per minute; exceeding this speed leads to missed defects. With technological advancements, most existing technologies utilize fabric defect detection equipment. This equipment uses visual recognition methods to detect defects in fabric, and current equipment can replace manual inspection. However, existing technologies have the following problems: fabric wrinkles easily form when moving on the equipment, affecting the accuracy of defect detection. Therefore, there is a need for fabric defect detection equipment that can reduce fabric wrinkles to improve the accuracy of fabric detection. Utility Model Content

[0020] The present invention will be described in detail below with reference to specific embodiments.
[0021] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.
[0022] like Figures 1 to 3 As shown, this utility model provides a fabric defect detection device, including a base 1, a side plate 2 on the base 1, a feeding component 3, an ironing component 4, a fabric inspection component 5 and a winding component 6 on the side plate 2. The fabric to be inspected is placed on the feeding component 3, and the fabric passes through the ironing component 4 and the fabric inspection component 5 in sequence before being wound up by the winding component 6.
[0023] The ironing assembly 4 includes an ironing plate 40, a pressing seat 41, a pressure roller 43, and a telescopic drive component 42. The ironing plate 40 is fixedly installed on the side plate 2, and the telescopic drive component 42 is installed on the side plate 2. The telescopic drive component 42 is used to drive the pressing seat 41 to move closer to or away from the ironing plate 40. The pressing seat 41 is provided with multiple sets of pressure rollers 43, which are used to press the fabric onto the ironing plate 40. The ironing plate 40 is provided with a heating element and a temperature sensor.
[0024] With the above design, when the fabric passes through the ironing plate 40, the heating element inside the ironing plate 40 is energized, and the ironing plate 40 heats up. Combined with the pressure of the pressure roller 43, the wrinkles of the fabric will be ironed out, thereby improving the detection accuracy during subsequent automatic inspection by reducing wrinkles. The temperature sensor inside the ironing plate 40 can record the temperature of the ironing plate 40 to prevent the fabric from being burned by excessive temperature. When it is necessary to load the fabric, the operator can control the pressing seat 41 through the telescopic drive component 42, thereby controlling the pressure roller 43 to move away from the ironing plate 40. After the fabric passes through the ironing plate 40 and the fabric inspection component 5, the telescopic drive component 42 drives the pressing seat 41 to move closer to the ironing plate 40, ensuring that the pressure roller 43 can press the fabric firmly onto the ironing plate 40.
[0025] In this embodiment, the fabric inspection component 5 includes an automatic fabric inspection area 50 and a manual fabric inspection area 51. The automatic fabric inspection area 50 is located above the ironing component 4 and along the fabric's forward direction, while the manual fabric inspection area 51 is located behind the automatic fabric inspection area 50.
[0026] In this embodiment, the automatic fabric inspection area 50 includes a base plate 500, an inspection camera 503, a soft light 502, and a labeling component 501. The manual fabric inspection area 51 includes an inspection platform 510 and a supplementary light 511. The base plate 500 is fixedly installed on the side plate 2. The labeling component 501, the inspection camera 503, and the soft light 502 are all installed directly above the base plate 500. The inspection camera 503 is used to take pictures of the fabric passing over the base plate 500. A control computer 9 is provided on the side plate 2, and the captured pictures are transmitted to the control computer 9 for defect identification. The soft light 502 is used to supplement the light on the fabric on the base plate 500. The inspection platform 510 is installed at an angle on the side plate 2, and the supplementary light 511 is located above the inspection platform 510.
[0027] Furthermore, the labeling component 501 includes a crossbar, a servo motor, a cylinder, a negative pressure suction cup, and a label chamber. The crossbar is fixedly installed on the side plate 2. The servo motor is used to drive the cylinder to slide on the crossbar. The cylinder is used to drive the negative pressure suction cup to move closer to or away from the base plate 500. The negative pressure suction cup can pick up the label in the label chamber and stick it to the base plate 500.
[0028] With the above design, the ironed fabric is guided onto the base plate 500. A soft light 502 illuminates the fabric on the base plate 500. A detection camera 503 detects any defects on the fabric. If a defect is found, the camera records the location of the defective area and sends the information to the control computer 9. The control computer 9 then controls a negative pressure suction cup to pick up the label. Next, it controls a servo motor to bring a cylinder to the front of the defective area. The control computer 9 controls the cylinder to descend with the label at the appropriate time (when the defective area is approximately directly below the cylinder) according to the fabric's conveying speed, thus affixing the label to the defective area or its vicinity, completing the automatic detection and labeling process.
[0029] Fabrics that have passed automatic inspection will pass through the fabric inspection platform 510. The fabric inspection platform 510 is set up in an open manner to facilitate secondary inspection by staff. The supplementary light 511 on the fabric inspection platform 510 can illuminate the fabric on the fabric inspection platform 510 so that staff can observe it.
[0030] In this embodiment, both the base plate 500 and the fabric inspection platform 510 are equipped with three primary color LED backlights.
[0031] Through the above design scheme, the control computer 9 can detect whether there are defects on the fabric based on the information in its database and the data fed back by the detection camera 503. When a defect is detected, the control computer 9 will send an instruction to the labeling component 501 and record the information. The labeling component 501 will then label the defective area. The three primary color LED backlight panels in the base plate 500 and the fabric inspection platform 510 can emit different colors of light. The control computer 9 can control the background color of the base plate 500 and the fabric inspection platform 510 according to the color of the fabric, making the damaged area more obvious and further improving the detection accuracy of the detection camera 503 and manual inspection.
[0032] In this embodiment, a swing arm 7 is provided between the feeding assembly 3 and the ironing assembly 4, and the swing arm 7 can adjust the tension of the fabric.
[0033] In this embodiment, both the feeding assembly 3 and the winding assembly 6 include a chuck 30, a clamping drive 31, and a rotation drive 32. The clamping drive 31 is mounted on the base 1 and has two sets of chucks 30 mounted on it. The clamping drive 31 can drive the two sets of chucks 30 to move closer or further apart from each other. The rotation drive 32 is mounted on the chucks 30 and is used to drive the chucks 30 to rotate.
[0034] In this embodiment, the clamping drive 31 includes a slide, a bidirectional lead screw with forward and reverse threads, and a stepper motor. The slide is fixedly installed on the base 1, and the stepper motor is installed on the slide. The stepper motor can drive the bidirectional lead screw with forward and reverse threads to rotate. The stepper motor can drive the two sets of chucks 30 to move closer or further apart through the bidirectional lead screw with forward and reverse threads. The chucks 30 can slide on the slide. Under the guidance of the slide, the movement of the chucks 30 can be smoother.
[0035] With the above design scheme, when feeding, the operator can control the chuck 30 in the feeding component 3 to unfold to both sides through the control computer 9. After the fabric roll is placed in the clamping range of the chuck 30, the operator can control the chuck 30 to move closer so that the fabric roll can be firmly clamped by the chuck 30. Similarly, the operator can fix the material core for winding into the chuck 30 of the winding component 6 through the same operation.
[0036] In this embodiment, multiple sets of guide rollers 8 are provided on the side plate 2. The guide rollers 8 are evenly arranged between different components to guide the fabric to transition evenly between different components.
[0037] The fabric defect detection device provided by this utility model, compared with the prior art, the fabric output from the feeding component 3 is guided by the swing arm 7 to the ironing plate 40. The pressure roller 43 presses the fabric onto the ironing plate 40 and irons the fabric flat. The ironed fabric first passes through the automatic fabric inspection area 50, where it is inspected by the inspection camera 503 and then the defective areas are labeled. The inspected and labeled fabric then passes through the manual fabric inspection area 51, which facilitates workers to check for defects and ensures the accuracy of fabric inspection.
[0038] Where there is no conflict, the above embodiments and features can be combined with each other.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
