Foot pads 102 are fixedly installed on both sides of the columns 101. The foot pads 102 are provided with adaptation holes on the side close to the columns 101 and the side close to the ground. The foot pads 102 can be confined between the ground and the columns 101 by using an adapted fastening device, so that the columns 101 are fixed on the ground. A cross column 103 is fixedly installed between the columns 101. The columns 101, the foot pads 102 and the cross column 103 form an integral bracket 1.

[0020] A cross piece 2 is fixedly installed on one side of the bracket 1, and a clamping ring is provided on the surface of the cross piece 2. A clamping shaft 3 is fixedly connected to the inner ring of the clamping ring, and a grating 4 is fixedly connected between the clamping shafts 3. The top of the grating 4 is a grating detection. The grating 4 is electrically connected to the signal transmitter 111 to detect whether there is material flow on the top of the grating 4. A cross plate 5 is fixedly installed on one side of the bracket 1 above the cross piece 2. The cross plate 5 has two cross grooves on one side away from the column 101. Four fixed blocks 6 are fixedly installed inside the two cross grooves, and two fixed blocks 6 are grouped together. A long plate 7 is fixedly installed on the bottom surface of the fixed block 6, and a support column 8 is fixedly installed between the long plate 7 and the fixed block 6. The fixed block 6 and the support column 8 cooperate to fix the position of the long plate 7 to prevent the long plate 7 from being offset. An extension plate 9 is fixedly installed at the groove of the long plate 7, and a limiting column 10 is fixedly installed between the extension plates 9.

[0021] See also Figure 2-Figure 3A first camera 11 is fixedly connected between the first group of extension plates 9, and a signal transmitter 111 is fixedly installed on the top of the first camera 11. The first camera 11 has a reporting function. When the first camera 11 detects that there are defects in the area, all areas are photographed for detection, and detailed defect locations and picture information are uploaded to the network through the signal transmitter 111. In order to detect the number of defects on the surface of the material, the camera area of ​​the first camera 11 divides the surface of the material into 9 areas for shooting and detection. A total of 9 areas are divided. The white pole ear area is more susceptible to defects than the gray coating area. Due to the different locations of defects, the actual effects are also different. Therefore, the number of defects is counted in each area, and the edge notch specification is ≥0.02mm, the pole ear particle specification is ≥0.05mm, the pole ear oil spot is ≥0.05mm, the pole ear wrinkle is ≥0.1mm, pinhole defects, etc. Level classification: pinhole A: 0.01mm-0.03mm, pinhole B: 0.03mm-0.05mm, pinhole C: 0.05mm-0.10mm, pinhole D: 0.10mm-0.20mm, pinhole E: 0.20mm-infinity. According to user needs, each defect reaches a specified number or more and a shutdown alarm is triggered. A second camera 12 is fixedly connected between the second group of extension plates 9. The second camera 12 is a confirmation detection camera. When the first camera 11 detects defects in a certain area, a yellow warning signal is transmitted to the alarm light 13. The second camera 12 conducts detailed inspections on the defect type, number and specifications. When the number of defect density per unit length reaches the threshold, the alarm light 13 continues to alarm. The employee judges according to the standard whether the roll of material should be unloaded and returned to the warehouse. The employee can also use the reset button 14 to reset and continue to complete the coating.

[0022] See also Figure 1-Figure 4 An alarm light 13 is fixedly installed in the middle of the horizontal column 103, and a reset button 14 is fixedly installed on the top of the horizontal column 103, which is located on one side of the alarm light 13. The alarm light 13 and the reset button 14 are electrically connected to each other, and the first camera 11, the second camera 12 and the alarm light 13 are electrically connected. According to customer needs, thresholds are set for different areas and different defect types to control the density of defects.

[0023] The first camera 11 is connected to the software through the signal transmitter 111. The user controls the detection specifications of the first camera 11 through the software settings. When the signal transmitter 111 captures defects in a certain area, the capture function is started to capture pictures and upload them to the software. Due to the differences in the materials and models of the inspection materials, the user can set the defect type and size specifications of the first camera 11 through the software. The software has functions such as data statistics and parameter configuration. The signal and picture information transmitted by the signal transmitter 111 inside the software can generate time display, product model, PLC monitoring, data display, defect line graph, defect type pie chart and other functions after automatic network recognition, providing users with digital display effects.

[0024] Working principle: By placing the device on the material inspection line, the material is made to flow between the grating 4 and the first camera 11 in a fixed manner. When the material passes through the grating 4 and the first camera 11, the grating 4 detects the size and product model of the material, and uploads the information to the software background for the user to view digitally. The first camera 11 monitors the surface of the material, and divides the surface of the material into 9 areas, focusing on the high-incidence defects in certain areas. For example, the two sides of the material are prone to edge gap defects. After the first camera 11 detects the existence of defects on the surface, it captures all areas and uploads them to the software background for the user to view, and then sends a yellow warning signal to the alarm light 13. The second camera 12 receives this signal. After the number is detected, the area marked by the first camera 11 is focused on detection, and the defect type and size of the defect are identified, including defects in all areas. When the detected defect specifications and quantity exceed the threshold set by the user, a red alarm signal is transmitted to the alarm light 13 to remind the user that the material has defects. After manual confirmation, the user can choose to discard the material and press the reset button 14 to reset. After the software background receives the defect image transmitted by the first camera 11, it marks the image according to the accurate identification of the second camera 12, marks the defect location, and automatically generates a line chart and a pie chart through the defect type, size specification and defect quantity identified by the second camera 12, so that the user can digitally view the defect situation of the material.
