Description

TECHNICAL FIELD

[0001] The application belongs to the field of cashmere product detection, and particularly relates to a cashmere product surface detection device. BACKGROUND

[0002] As a precious animal fiber of "soft gold" level, the quality detection of cashmere products is directly related to product value and consumer rights and interests. China, as the world's largest cashmere producing and exporting country, accounts for more than 70% of the global annual output, but the cashmere detection technology has long been faced with problems such as low automation and insufficient intelligence. According to the data disclosed at the 9th International Cashmere Detection Technology Seminar in 2025, more than 60% of cashmere products in the industry still rely on manual visual inspection or semi-automatic detection equipment, resulting in low detection efficiency and high false detection rate (averaging 12%-15%), which seriously restricts the high-quality development of the industry.

[0003] The existing cashmere product surface detection device adopts a traditional mechanical stretching method, which is only suitable for static scenes and cannot solve the real-time wrinkles generated during the conveying process. Moreover, mechanical stretching can easily damage the fibers of cashmere products. Since cashmere fibers are thin and fragile, traditional mechanical stretching applies tension through hard structures such as clamps and pressure plates, which can easily cause fiber breakage, fluffing, or local deformation, damaging the original texture and integrity of cashmere products. Moreover, the mechanical stretching force is difficult to accurately control, and excessive tension can cause product size deviation, while insufficient tension cannot effectively remove wrinkles, further increasing the quality risk and detection error during the detection process.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0035] Example 1

[0036] This invention provides a surface inspection device for cashmere products, such as... Figures 1 to 7 As shown, the device includes a frame 1, a cashmere conveying roller 2, a display screen 3, and a double-sided laying detection assembly. The frame 1 serves as the supporting structure for the detection device. The cashmere conveying roller 2 is mounted on the frame 1 and is used to convey cashmere products. The display screen 3 is located on the outside of the frame 1 and is used to display detection data. The double-sided laying detection assembly includes a surface defect camera module 6, a fabric flattening roller 7, a transmission assembly, a rolling element 15, and a bottom defect detection module 22. The fabric flattening roller 7 is rotatably mounted inside the frame 1 and is located at the front end of the conveying path of the cashmere conveying roller 2. The rolling element 15 is connected to the fabric flattening roller 7 through the transmission assembly, and the rolling element 15 is in contact with the surface of the cashmere product. The bottom defect detection module 22 is built into the fabric flattening roller 7 and is used to detect bottom defects of the cashmere product. The surface defect camera module 6 is mounted inside the frame 1 and is located above the cashmere product, and is used to detect surface defects of the cashmere product. When the fabric flattening roller 7 rotates, it drives the rolling element 15 to move synchronously through the transmission assembly to unfold the cashmere product along the plane.

[0037] The existing cashmere product surface detection device adopts a traditional mechanical stretching method, which is only suitable for static scenes and cannot solve the wrinkles generated in real time during the conveying process. Moreover, mechanical stretching can easily damage the fibers of the cashmere product. Since cashmere fibers are thin and fragile, traditional mechanical stretching applies tension through hard structures such as clamps and pressure plates, which can easily cause fiber breakage, fluffing, or local deformation, damaging the original texture and integrity of the cashmere product. Moreover, it is difficult to accurately control the mechanical stretching force. Excessive tension can cause size deviation, while insufficient tension cannot effectively remove wrinkles, further increasing the quality risk and detection error during the detection process.

[0038] Compared with the traditional mechanical stretching method, the device significantly improves the detection process by using double-sided detection components. When the fabric flattening roller 7 rotates, the transmission assembly drives the rolling member 15 to move synchronously (the fabric flattening roller 7 drives the cashmere product to move horizontally, and the rolling member 15 rotates longitudinally at the bottom end of the cashmere product). Dynamic flattening of the cashmere product is achieved through rolling friction, avoiding fiber breakage, fluffing, or local deformation caused by direct contact with hard structures such as clamps and pressure plates, protecting the texture and integrity of the cashmere product. This design is suitable for the conveying process and can eliminate wrinkles generated during conveying in real time. The flattening force is accurately controlled through mechanical transmission, avoiding size deviation caused by excessive tension and solving the problem of insufficient tension for wrinkle removal, effectively reducing the quality risk and detection error.

[0039] In use, the cashmere product is placed at the front end of the cashmere conveying roller 2 (by hand or mechanical hand), and the cashmere conveying roller 2 is started to pull the product along the conveying path. When the cashmere product contacts the surface of the fabric flattening roller 7 and continues to move, the fabric flattening roller 7 is driven to rotate synchronously by friction. During the rotation of the fabric flattening roller 7, the internal transmission assembly acts to drive the rolling member 15 to rotate, uniformly expanding the cashmere product in the width direction through rolling friction, and eliminating wrinkles generated during conveying in real time.

[0040] The flattened cashmere product is continuously pulled through the detection area by the conveying roller, and at this time, the surface defect camera module 6 located above and the bottom defect detection module 22 built into the transmission assembly simultaneously collect fabric double-sided images.
