Automatic comprehensive detection device for plates

The invention relates to the technical field of plate detection, and discloses an automatic comprehensive plate detection device which comprises a supporting rack, the left side and the right side of the supporting rack are fixedly connected with plate groove fixing ends, the top ends of the plate groove fixing ends are fixedly connected with downward pressing supporting frames, and the top ends of the downward pressing supporting frames are fixedly connected with hydraulic rods. A detection device is arranged below the downward pressing bracket, a vertical guide rod is slidably connected to the inner side of the supporting rack, a top platen is fixedly connected to the top end of the vertical guide rod, and a bottom frame plate is fixedly connected to the bottom end of the vertical guide rod. The uneven area where a plate is located can be judged according to the intensity of a reflected light source received by a light source reflected light sensor, meanwhile, a detection end shell is pressed downwards to p
