[0030] The working principle of a water-cooled plate flatness and contour detection device provided by the utility model is as follows: when in use, the water-cooled plate is placed on the tray 3, the tray 3 is a full-profile design of the flow channel plate to ensure that the product flow channel is destroyed under subsequent pressure conditions, the PLC controller 9 is regulated, the servo motor 12 is running, the output shaft of the servo motor 12 drives the gear 13 to rotate, the gear 13 is meshed and connected with the stationary rack 11, and then the gear 13 drives the bottom plate 2 to move along the frame 1 to the left through the servo motor 12, and the bottom plate 2 drives the water-cooled plate to move synchronously through the tray 3. At this time, the line laser sensor 7 is located on the right side of the mobile gantry 6. The line laser sensor 7 emits laser light to scan the water-cooled plate passing below.

After the water-cooled plate is pressed, the electric motor inside the mobile gantry 6 is moved. The operation of the machine drives the line laser sensor 7 to move horizontally, longitudinally and vertically, and then the light of the line laser sensor 7 passes through the detection hole on the upper surface of the pressure plate 81, and scans the height information of the opening position of the water-cooled plate again to detect the flatness information of the water-cooled plate under the pressure state. After the detection is completed, the PLC controller 9 controls the sponge suction cup 10 to work through the solenoid valve, and the sponge suction cup 10 vacuum absorbs the water-cooled plate, and the pressure plate 81 moves up and resets, while driving the water-cooled plate to move up and separate from the tray 3, and the tray 3 moves to the right and resets, and then the sponge suction cup 10 stops working and separates from the water-cooled plate, and the water-cooled plate is placed on the electric conveyor belt 4.
