[0033] The working principle of the single board surface detection device provided by the utility model is as follows:

[0034] In the use of the device, when the plate to be detected moves to the column conveyor, the main conveyor moves the plate to the detection assembly 2, when the side wall of the plate abuts against the outer wall of the baffle 52, the value of the pressure sensor 51 changes, and the controller 6 detects the vertical change of the pressure sensor 51, that is, the detection assembly 2 can work;

[0035] First, the vertical cylinder 232 in the detection assembly 2 corresponding to the long side of the main conveyor can work, when the vertical cylinder 232 drives the clamping piece 233 to move vertically to the outer wall of the plate, the horizontal cylinder 231 can work, so that the clamping piece 233 moves horizontally, when the outer wall of the clamping piece 233 abuts against the side wall of the plate, the vertical cylinder 232 can be controlled to retract, so that the plate moves to the height corresponding to the backlight plate 212;

[0036] Then the horizontal electric push rod 241 can be controlled to extend, so that the planar detection camera 25 on the support frame 242 moves to the opposite part of the planar detection camera 25 on the support disc 22, at this time, the two planar detection cameras 25 can take pictures of the upper and lower surfaces of the plate, and upload the pictures to the controller 6 for comparison and detection;

[0037] During this process, the working irradiation lamp 243 can irradiate light to the plate, at this time, the projection of the side wall of the plate is projected on the backlight plate 212, and the working projection detection camera 214 can take pictures of the projection of the plate and upload them to the controller 6 for comparison, so as to realize multi-directional detection of the plate;

[0038] After completing the detection of the projection of one side of the plate, the other two groups of horizontal cylinders 231 and vertical cylinders 232 can be controlled to work, so that the side walls of the other two clamping plates abut against the side wall of the plate, and then the previous horizontal cylinder 231 and vertical cylinder 232 can be operated to separate the previous clamping plate from the outer wall of the plate, and move to the upper side of the plate to avoid blocking the projection of the side wall of the plate in the later stage;

[0039] After completing the clamping and replacement of the clamping plate, the rotating motor 211 can be controlled to work, and the working rotating motor 211 can rotate and adjust the plate and the clamping plate, so as to rotate the other side of the plate to the opposite part of the irradiation lamp 243, after completing the adjustment of the plate, the planar detection camera 25 and the projection detection camera 214 can be repeatedly operated to detect the plate from multiple angles, so as to improve the accuracy of the detection of the plate;

[0040] When the controller 6 completes the comparison detection of the plate, the screw rod 31 and the vertical electric push rod 33 can be controlled to work, and the numerical electric push rod can drive the detection component to move upwards, so that the bottom of the detection component moves above the baffle 5; the rotating screw rod 31 can drive the sliding plate 32 to move on the fixed frame 3 in the direction of approaching the horizontal conveying belt through the threaded structure; if the detection result of the plate meets the standard, the plate can be placed on the main conveying belt 1; if the detection result of the plate does not meet the standard, the plate can be placed on the auxiliary conveying belt 4, so that the automatic classification of the plate can be realized.
