The frame installation position in the lateral translation assembly 41 is at the rear side of the visual camera 111, so as to avoid interference problems when the visual camera 111 moves downward. The longitudinal translation assembly 42 is mainly composed of a moving frame, a servo motor, a screw, a guide rod and a moving block.

The tape-type label paper mainly consists of a rubber cylinder, a release layer and a label. The label is adhered to the release layer and can be peeled off by external force. The rubber cylinder on the tape-type label paper is installed on one of the rollers 603. The release layer passes through the guide wheel 604 and the support platform 602 and is wound onto another roller 603. The corresponding roller 603 is then driven by the second motor 605 to rotate, so as to release the tape-type label paper.The release layer is supported by the support platform 602, so that the suction nozzle 51 can play a supporting role when it contacts the label.

[0028] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0029] During operation, the cloth is spread flat on the inspection table 305, and the bidirectional screw rod 203 is driven to rotate by the first motor 204, and the two smoothing rods 201 are driven to approach each other by the threaded column 202 until the two smoothing rods 201 move to the middle position of the inspection table 305, and then the support frame 302 is pushed upward by the electric push rod 301, so that the cloth on the inspection table 305 contacts the bottom of the smoothing rod 201, and then the two smoothing rods 201 are driven away from each other by the first motor 204. During the movement of the smoothing rod 201, the wrinkled parts of the cloth are smoothed to both sides, so as to facilitate the subsequent Before testing the fabric, different standard color cards 9 are inserted into the card slot 804, and then the third motor 801 drives the rotating shaft 802 to rotate, so that the standard color card 9 of the corresponding color is moved to the bottom of the visual camera 111, and the image on the standard color card 9 is collected by the visual camera 111 as an image comparison reference. After the image reference of the visual camera 111 is completed, the notch 805 on the turntable 803 is driven by the third motor 801 to be located below the visual camera 111, and then the visual camera 111 is pushed downward through the notch 805 by the electric telescopic rod 10. The visual camera 111 is moved until it is under the turntable 803 and descends to a height suitable for collecting images of the fabric. Then, the visual camera 111 extracts the image features of the fabric, performs pattern recognition and other processing to identify defects on the surface of the fabric, thereby improving the detection effect and avoiding omissions in manual detection. After that, marking is performed according to the results of image processing. During marking, the suction nozzle 51 on the telescopic cylinder 5 is controlled to move within the travel range of the moving mechanism 4 through the mutual cooperation of the lateral translation component 41 and the longitudinal translation component 42. When the suction nozzle 51 moves to the support table 602, the suction nozzle 51 is moved to the support table 602. When the fabric is above the label tape, the telescopic cylinder 5 pushes the suction nozzle 51 to move downward, so that the suction nozzle 51 contacts the label tape. At this time, the suction nozzle 51 generates negative air pressure through the external air control unit. At this time, under the action of the negative air pressure, the suction nozzle 51 is pulled upward in cooperation with the telescopic cylinder 5, so as to peel off the label suction nozzle 51 on the tape. Afterwards, according to the position of the defect on the fabric surface, the moving mechanism 4 controls the suction nozzle 51 to move to the corresponding position, and then cooperates with the telescopic cylinder 5 to push the suction nozzle 51 to move downward until the label adsorbed on the suction nozzle 51 is attached to the fabric, so that the defect points on the fabric can be observed more intuitively, reducing the difficulty of work.
