[0002] The steel coil edge inspection machine is a device used to detect steel coil edge defects. It is mainly used in steel manufacturing and processing industries. However, the existing steel coil edge inspection machines still have certain defects when used, such as;

[0003] During use, the existing inspection requires the steel coil to be fixed in position, so the clamping structure will scratch the side of the steel coil, causing damage to the edge of the steel coil. In addition, the inspection mechanism is to install cameras on both sides of the transport chain to take pictures and scan the photos. For the defective positions, the quality inspector needs to go to the site to visually judge the steel coil, so the overall observation efficiency is low;

[0004] In order to overcome the above-mentioned defects, prior art 1 (Chinese patent with application number CN202020010992.7 and application date 2020-01-04) is a device for reducing the scratching of the edge of the steel coil, including a signal light 1L, a signal light 2L, a signal light 3L, a distance detection switch, and a photoelectric switch; there are two distance detection switches, which are respectively fixed on the inner sides of the two clamp arms of the horizontal coil clamp, and are used to detect the distance between the steel coil and the clamp arm; the two distance detection switches are both connected to the signal light 1L; there are two photoelectric switches, one photoelectric switch is fixed on the inner side of the clamp arm close to the clamp hook of the horizontal coil clamp, and the other photoelectric switch is fixed at the bottom of the clamp arm of the horizontal coil clamp, and a signal receiver corresponding to the photoelectric switch is fixed on the clamp arm on the other side of the horizontal coil clamp; one photoelectric switch is connected to the signal light 2L, and the other photoelectric switch is connected to the signal light 3L. The overall structure is reasonable, which can reduce the scratching of the horizontal coil clamp on the edge of the steel coil, thereby improving the yield rate;

[0006] And prior art 3 (Chinese patent with application number 201910789237.5 and application date 2019-08-26) a horizontal steel coil edge defect local detection and judgment system and its judgment method, which are connected to the edge defect detection system signal, and include a working platform and a detection platform; the working platform is provided with a transverse electric motor, and the transverse electric motor is connected to a transverse screw rod through a transmission structure, and the detection platform is arranged on the transverse screw rod, and sliding rods parallel to the transverse screw rod are arranged on both sides of the transverse screw rod; the detection platform is provided with a detection tower and a longitudinal transmission motor, and a longitudinal screw rod is provided in the detection tower, and the longitudinal transmission motor is connected to the longitudinal screw rod through a transmission structure, and a laser rangefinder is provided on the longitudinal screw rod. The overall structure does not require manual on-site confirmation, thereby improving the depth measurement accuracy of the steel coil finishing edge loss, coiling edge loss, and edge cracks.

[0007] Although the existing technology can improve the overall detection efficiency, during the operation, the steel coil is limited by the horizontal coil clamp, which can only reduce the scratching of the edge of the steel coil and cannot effectively solve the damage problem. In addition, the driving structure is used to drive the laser ranging sensor for mobile detection. The overall driving structure is cumbersome, which increases the overall installation and maintenance costs. During transportation, the steel coil is easily affected by the external environment and thus contaminated with dust and other particles, making the overall detection inconvenient, thereby reducing the overall detection efficiency.

[0008] In response to the above problems, it is urgent to carry out innovative design based on the original steel coil edge inspection machine based on machine vision.
