Description

Technical Field

[0001] This invention relates to a method for handling defects in fabric inspection, and more specifically, to an intelligent method for handling defects in fabric inspection. Background Technology

[0002] In textile workshops, during fabric processing, debris such as fly ash can fall onto the fabric. Processing defects can also occur, such as holes, bumps, or dents. Before becoming a finished product, the fabric needs to be inspected to check for defects. Current technology typically involves passing the fabric through an inspection machine, relying on manual visual inspection to identify surface defects such as fly ash and holes. If defects are found, they are still manually repaired or removed. Prolonged inspection can cause eye fatigue. Existing inspection methods, regardless of the type of defect, rely entirely on manual identification and judgment. Relying solely on manual inspection is inefficient and prone to omissions. Summary of the Invention

[0003] The technical problem to be solved by this invention is to provide an intelligent method for handling defects in fabric inspection, thereby improving the efficiency of fabric inspection and defect handling.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A method for intelligently handling defects in fabric inspection, wherein the same fabric to be inspected sequentially passes through a pre-inspection area, a marking area, a working area, and a main inspection area; the method includes: Step 10: When the fabric to be inspected enters the pre-inspection area, the surface of the fabric is photographed by image acquisition to determine whether there are defects. If so, the type of defect is determined and step 20 is executed. Step 20: When the fabric to be inspected enters the marking area, the defects are marked according to the type of defect. Step 30: When the fabric to be inspected enters the work area, some defects are eliminated according to the marking information; Step 40: When the fabric to be inspected enters the main inspection area, eliminate any remaining defects according to the marking information.

[0005] As a preferred example, in step 10, the types of defects include a first defect and a second defect. The first defect is a defect formed on the fabric during the fabric making process; the second defect is debris attached to the surface of the fabric.

[0006] As a preferred example, the first defect includes holes in the fabric, or protrusions or depressions formed during the fabric manufacturing process; the second defect includes lint or hair.

[0007] As a preferred example, step 20 includes: If the defect type is the first defect, then affix the first colored ring-shaped adhesive tape around the first defect. If the defect type is the second defect, then a second colored tape is pasted on the second defect, covering all or part of the second defect.

[0008] As a preferred example, the first colored annular adhesive tape and the second colored adhesive tape have different color schemes.

[0009] As a preferred example, step 20 includes: If the defect type is the first defect, then the first color pigment is sprayed onto the first defect; If the defect type is the second defect, then a second colored tape is pasted on the second defect, covering all or part of the second defect.

[0010] As a preferred example, the first colored pigment and the second colored adhesive tape have different color schemes.

[0011] As a preferred example, step 30 further includes: Based on the type of defect, obtain the location information of the second colored tape; Based on the position information of the second colored tape, the robotic arm located in the work area is positioned opposite the second colored tape located in the work area; A robotic arm is used to peel off the second colored tape from the fabric to be inspected, thus removing the second defect from the fabric.

[0012] As a preferred example, step 40 includes: Obtain the position information of the first colored ring-shaped adhesive tape; The first defect located within the first colored annular adhesive tape is processed; The first colored ring of adhesive tape is torn off from the fabric to be inspected using a robotic arm.

[0013] As a preferred example, step 40 includes: Obtain the position information of the first colored pigment; The first defect located at the first colored pigment is treated; The method further includes: Step 50: Move the fabric to be inspected from the main inspection area into the washing area, wash the first color pigment, and remove the color from the fabric to be inspected. Step 60: Move the fabric to be inspected from the rinsing area to the drying area and dry it.

[0014] Compared with existing technologies, the present invention provides an intelligent method for handling defects in fabric inspection, which can improve the efficiency of fabric inspection and defect handling. The intelligent method for handling defects in fabric inspection includes: Step 10: When the fabric to be inspected enters the pre-inspection area, the fabric surface is photographed using image acquisition to determine whether defects exist. If so, the type of defect is determined, and step 20 is executed; Step 20: When the fabric to be inspected enters the marking area, the defects are marked according to their types; Step 30: When the fabric to be inspected enters the working area, some defects are eliminated based on the marking information; Step 40: When the fabric to be inspected enters the main inspection area, the remaining defects are eliminated based on the marking information. This method intelligently identifies defect types and uses different processing methods for different types of defects, improving the efficiency of fabric inspection and defect handling, as well as the reliability of the processing. Attached Figure Description

[0015] Figure 1 This is a flowchart of a method according to an embodiment of the present invention. Detailed Implementation

[0016] The technical solution of the present invention will now be described in detail with reference to the accompanying drawings.

[0017] In this embodiment of the invention, the same fabric to be inspected sequentially passes through a pre-inspection area, a marking area, a working area, and a main inspection area. These areas are used to inspect the quality of the fabric and repair defects. The pre-inspection area is mainly used to determine whether defects exist on the fabric and what types of defects exist. The marking area is mainly used to mark defects on the fabric according to their types. The working area and the main inspection area are used to clean or repair defects.

[0018] like Figure 1 As shown in the figure, an intelligent processing method for defects in fabric inspection according to an embodiment of the present invention includes: Step 10: When the fabric to be inspected enters the pre-inspection area, the surface of the fabric is photographed by image acquisition to determine whether there are defects. If so, the type of defect is determined and step 20 is executed. Step 20: When the fabric to be inspected enters the marking area, the defects are marked according to the type of defect. Step 30: When the fabric to be inspected enters the work area, some defects are eliminated according to the marking information; Step 40: When the fabric to be inspected enters the main inspection area, eliminate any remaining defects according to the marking information.

[0019] In the method of the above embodiment, defects on the fabric surface are classified. Defect types include first defects and second defects. First defects are defects formed on the fabric during the fabric manufacturing process. For example, first defects are holes in the fabric, or raised or recessed areas formed during fabric manufacturing. First defects are inherent defects of the fabric itself. Second defects are impurities attached to the fabric surface, such as lint or hair. Second defects are external impurities attached to the fabric surface. In step 20 of this embodiment, defects are marked according to their type. Different types of defects are marked differently. This makes it easier for subsequent steps to distinguish between different types of defects. Steps 30 and 40 of this method handle two different types of defects respectively. Existing technologies only set up a main inspection area, and all defects are handled manually, which is inefficient and prone to omissions. The method of this embodiment, however, uses different processing methods for different types of defects, reducing manual processing and improving processing efficiency. In addition, by taking pictures of the fabric surface through image acquisition, the presence of defects can be determined, reducing or avoiding the omission of defects and improving the reliability of the process.

[0020] Preferably, step 20 includes: if the defect type is a first defect, then a first colored ring-shaped adhesive tape is pasted around the first defect; if the defect type is a second defect, then a second colored adhesive tape is pasted on the second defect, the second colored adhesive tape covering all or part of the second defect.

[0021] In the preferred embodiment described above, a first colored annular adhesive tape is provided, surrounding the first defect within the tape. This facilitates the location of the first defect during repair. A second colored adhesive tape is then provided, adhering to the fabric and covering all or part of the second defect. Simultaneously, the second colored adhesive tape adheres to both the fabric and the second defect. To distinguish between the two types of defects, preferably, the first and second colored adhesive tapes have different color schemes. Using different color schemes for the first and second colored adhesive tapes facilitates the identification of different defects. For example, the first colored annular adhesive tape may be red, and the second colored adhesive tape may be yellow. To quickly identify the location of different types of defects, both the first and second colored adhesive tapes have different color schemes than the fabric.

[0022] As another preferred example, step 20 includes: if the defect type is a first defect, then spraying a first colored pigment onto the first defect; if the defect type is a second defect, then pasting a second colored tape onto the second defect, the second colored tape covering all or part of the second defect.

[0023] In this preferred embodiment, the treatment of the second defect is the same as in the previous preferred embodiment, both using a second colored adhesive tape for adhesion. The first defect is treated by spraying a first colored pigment. When the first colored ring-shaped adhesive tape is pasted onto the fabric, a robotic arm is used to press the tape to adhere it to the fabric for positioning. When the first defect is a hole in the fabric, the robotic arm presses the tape. Since the tape is close to the hole, the force applied by the robotic arm may enlarge the hole size. Therefore, spraying the first colored pigment is used to position the first defect without damaging it. The first defect is located within the sprayed area of ​​the first colored pigment. Preferably, the first colored pigment and the second colored adhesive tape have different color schemes. By using different color schemes for the first colored pigment and the second colored adhesive tape, it is easier to identify different defects. For example, the first colored pigment may be blue, and the second colored adhesive tape may be yellow. In order to quickly identify the location of different types of defects, the colors of the first colored pigment and the second colored adhesive tape are different from the colors of the fabric.

[0024] For the second defect, preferably, step 30 further includes: Step 301: Obtain the location information of the second colored tape according to the type of defect; Step 302: Based on the position information of the second colored tape, align the robotic arm located in the work area with the second colored tape located in the work area; Step 303: Use a robotic arm to tear off the second colored tape from the fabric to be inspected, thus removing the second defect from the fabric to be inspected.

[0025] The above preferred embodiment achieves the cleaning of the second defect. Since the second defect is marked with a second colored adhesive tape, the position information of the colored adhesive tape is first located; then, based on the position information of the second colored adhesive tape, the robotic arm in the work area is aligned with the second colored adhesive tape in the work area; finally, the robotic arm is used to peel the second colored adhesive tape off the fabric to be inspected. Because the second colored adhesive tape adheres to the second defect, the second defect on the fabric is cleaned simultaneously with the removal of the second colored adhesive tape. The second defect is hair or other debris, which is easily removed from the fabric using the second colored adhesive tape. This preferred embodiment achieves both the removal of the second colored adhesive tape from the fabric and the removal of the second defect from the fabric. This preferred embodiment, by using the second colored adhesive tape to separate the second defect from the fabric, is more efficient than manual cleaning.

[0026] For the first defect marked using the first colored circular adhesive tape, preferably, step 40 includes: Step 401: Obtain the position information of the first colored ring-shaped adhesive tape; Step 402: Process the first defect located within the first colored annular adhesive tape; Step 403: Use a robotic arm to tear off the first colored ring of adhesive tape from the fabric to be inspected.

[0027] The process of handling the first defect marked with a first colored ring-shaped adhesive tape begins by obtaining the location information of the tape. The first defect is located within the inner ring of the tape. The location of the first defect is quickly determined using the tape. Then, the defect is processed, for example, repairing holes in the fabric. After processing, a robotic arm is used to peel the first colored ring-shaped adhesive tape from the fabric to be inspected.

[0028] The above-described processing method uses a first colored circular adhesive tape to locate the first defect, which is simple. However, when using a robotic arm to attach and press the first colored circular adhesive tape onto the fabric, it may further damage the first defect, such as enlarging the hole. Therefore, preferably, for the first defect marked with a first colored pigment, step 40 includes: Obtain the position information of the first colored pigment; The first defect located at the first colored pigment is treated; The method further includes: Step 50: Move the fabric to be inspected from the main inspection area into the washing area, wash the first color pigment, and remove the color from the fabric to be inspected. Step 60: Move the fabric to be inspected from the rinsing area to the drying area and dry it.

[0029] In the preferred embodiment described above, the first colored pigment is a water-soluble pigment. The location information of the first defect is located using the first colored pigment. After obtaining the location information of the first defect, the first defect is treated. After treatment, the first colored pigment still remains on the fabric. Step 50 involves washing the fabric to be inspected to remove the first colored pigment. Step 6 involves drying the fabric to be inspected. Thus, after defect treatment, the fabric becomes a qualified finished product.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the specific embodiments described above. The specific embodiments and descriptions in the specification are merely for further illustrating the principles of the invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope. All such changes and modifications fall within the scope of the claimed invention.
