Full-automatic flatness detection mechanism for TRAY disc

The utility model relates to the technical field of TRAY disc detection, and discloses a TRAY disc full-automatic flatness detection mechanism. The device comprises a mechanism detection platform, a to-be-detected TRAY disc is placed on one side of the top surface of the mechanism detection platform, a defective TRAY disc is placed on one side, opposite to the to-be-detected TRAY disc, of the top surface of the mechanism detection platform, and a laser height measurement sensor is driven by an X-axis servo module and a Y-axis servo module to complete high-speed movement in a designated area. According to the equipment, high-speed detection is achieved, the detection speed reaches 6 seconds/PCS, the detection precision is high and reaches +/-0.03 mm, the detection process is non-contact detection, products cannot be damaged or scratched, defective products are automatically carried to a defective product stacking area after detection is completed, the automatic defective product stacking function is achieved,
