The time required, so that the control computer controls the sorting motor 36 to work at this time node, selects the tilt direction of the sorting plate 33, so as to play the role of sorting defective plates, and can control the work of the entire defective plate detection device. The upper right side of the No. 1 transmission structure 1 is provided with an online detection structure 2, which performs online detection on the passing plates to determine whether they are defective, and feeds back the information to the control computer, and the left end of the No. 1 transmission structure 1 is provided with a plate sorting structure 3, and the rear end of the sorting structure 3 is provided with a No. 2 transmission structure 4, which transports qualified plates to the next step, and the sorting The selection structure 3 includes a limit frame 31, which limits the position where the plate falls, ensuring that the plate on the No. 1 transmission structure 1 is sorted and falls on the material tray 5 or the No. 2 transmission structure 4. The left end of the limit frame 31 is close to the No. 1 transmission structure 1. A buffer structure 32 is provided to reduce the impact force between the plate and the limit frame 31 during the plate falling process. The triple protection has a good buffering protection effect. A sorting plate 33 is provided on the right side of the No. 1 buffer structure 32, and an extension plate 34 is symmetrically provided front and back below the sorting plate 33, which serves as an extension between the sorting plate 33 and the No. 2 transmission structure 4 and the material tray 5. The sliding trajectory of the plate material can reduce the impact force of the plate material falling and the risk of plate material damage. A rotating shaft 35 is provided at the right end of the sorting plate 33. The right end of the rotating shaft 35 is connected to a sorting motor 36. The sorting motor 36 receives the command of the control computer and selects the rotation direction. If the plate material is qualified, the sorting motor 36 drives the sorting plate 33 to tilt backward, so that the qualified plate material enters the No. 2 transmission structure 4 to continue the next process; if the plate material is defective, the sorting motor 36 drives the sorting plate 33 to tilt forward, so that the defective plate material slides to the material tray 5 and waits for centralized processing. This sorting method has a simple structure and high efficiency.

[0025] Further, if Figure 2 As shown, the left and right ends of the extension plate 34 are fixedly connected to the limit frame 31, and are connected by bolts and nuts, which are reliably fixed. The rear end of the extension plate 34 is located on the upper side of the No. 2 transmission structure 4, and a material tray 5 is provided under the front end of the extension plate 34 for holding defective plates.

[0026] Furthermore, a rectangular opening 37 is provided at the front right end of the limiting frame 31, and a revolving door 38 is hingedly connected to the upper end of the rectangular opening 37. By opening the revolving door 38, the material tray 5 inside the limiting frame 31 can be taken out, which is convenient for timely replacement. The height of the revolving door 38 is smaller than the height of the rectangular opening 37, which is convenient for opening the revolving door 38.

[0027] Further, if Figure 2 As shown, a rectangular groove 51 is provided at the lower end of the material tray 5, which is a fulcrum for the transport forklift, so that the forklift can transport the material tray 5 out of the rectangular opening 37, and a No. 2 buffer structure 39 is provided at the front side of the material tray 5, and is located on the limit frame 31. The structure of the No. 2 buffer structure 39 is the same as that of the No. 1 buffer structure 32, which plays a buffering and protective role for the defective plate sliding down from the sorting plate 33, preventing the defective plate from further colliding with the limit frame 31 to expand the damage and defects and make them irreparable.

[0028] Further, if Figure 3 As shown, the buffer structure No. 1 32 includes a groove 321, which provides an installation position for the elastic steel plate 322 and the airbag 323 to increase concealment. An elastic steel plate 322 is arranged in the groove of the groove 321, which has deformation buffering ability and also provides reinforcement and support for the buffer structure No. 1 32, which is the third buffer layer. An airbag 323 is arranged at the right end of the elastic steel plate 322, which is the second buffer layer. A silicone sheet 324 is arranged at the right end of the airbag 323, which is the first buffer layer. The silicone sheet has good weather resistance and can cope with multiple collisions of the plate without damage, so that the buffer structure No. 1 32 has a long service life, and an air nozzle 325 is arranged at the upper end of the airbag 323. The air nozzle 325 protrudes vertically from the surface of the limit frame 31. The airbag 323 will inevitably leak after long-term use, and air can be replenished through the air nozzle 325.

[0029] Further, if Figure 4As shown, the online detection structure 2 includes a pair of front-to-back symmetrical sliding brackets 21, a telescopic rod is provided at the lower end of the sliding bracket 21, the telescopic rod is controlled by the control computer to extend and retract at the same frequency, and the extension and retraction frequency of the telescopic rod can be selected on the control computer, a cutter 22 is provided between the sliding brackets 21, and the front and rear ends of the cutter 22 pass through the slide groove of the sliding bracket 21 and are fixedly connected to the telescopic rod inside it, when the telescopic rod is extended and retracted at the same frequency, it drives the cutter 22 to repeatedly move up and down at a uniform speed, so that the plate material that moves left and right at a uniform speed is evenly cut into the required size, and a connecting frame 23 is provided at the upper left end of the sliding bracket 21 to provide a mounting bracket for the CCD detection camera 24 and the infrared thermal imager 25, and a CCD detection camera 24 is provided at the lower end of the connecting frame 23. The CCD detection camera 24 is a line scanning camera with a very large sampling rate and It has high sensitivity and is suitable for accurate measurement, detection and inspection of objects on industrial production lines. The CCD detection camera 24 sends the detected defective plate information to the control computer. On the other hand, the scanned data of the CCD detection camera 24 is transmitted and stored in an external server for easy viewing by the staff. An infrared thermal imager 25 is arranged on the rear side of the CCD detection camera 24. The infrared thermal imager 25 is based on the law of thermal radiation. It measures the infrared radiation temperature of the plate surface and infers the surface temperature of the plate. When there are cracks in the plate, the material around the cracks will generate heat due to stress concentration, resulting in changes in surface temperature, so as to detect the existence and position of cracks in the plate. The infrared thermal imager 25 feeds back the detected defective plate information to the control computer. On the other hand, all the detection data of the infrared thermal imager 25 are also transmitted and stored in an external server.

[0030] Working process: First, operate the control computer to set the telescopic frequency of the telescopic rod inside the sliding bracket 21, and start the entire defective plate detection device; further, the telescopic rod inside the sliding bracket 21 works, driving the cutter 22 to repeatedly move downward at a uniform speed, so that the plate moving to the left at a uniform speed is evenly cut into the same size; further, the CCD detection camera 24 and the infrared thermal imager 25 work synchronously to perform double defect detection on the plate, and send and save the detection data to an external server. Further, if the detected plate is qualified, the sorting motor 36 rotates backward at a uniform speed and frequency. , so that the qualified plate material slides from the sorting plate 33 to the No. 2 transmission structure 4 and is transported to the next process. If a defective plate material is detected, the information is fed back to the control computer. The control computer infers the transportation time of the plate material detection point moving to the sorting plate 33 based on the rotation speed of the main roller in the No. 1 transmission structure 1 and the length of the transmission belt detected by the speed encoder, so that the control computer commands the sorting motor 36 to work according to the transportation time, so that the sorting motor 36 that originally rotates backward rotates forward, so that the defective plate material on the sorting plate 33 slides onto the material tray 5.
