A method for using a large-size flatness automatic detection component, characterized in that: The method for using a large-size automatic flatness detection component according to any one of claims 1 to 9 comprises the following steps: S1: Loading the workpiece to be tested, specifically, turning on the power supply, starting the first transmission motor (201), so that the first transmission motor (201) drives the four transmission blocks (206) to move in pairs in opposite directions through the first transmission screw (202) under the support of the protection box (102), and the transmission blocks (206) are slidably connected with the transmission frame (208), so that two adjacent transmission blocks (206) drive the two connecting slides (204) to slide on the inner side of the guide slide (203) through the adjustment rod (207) and the transmission frame (208), thereby facilitating the connecting slide (204) to drive the positioning clamping mechanism (4) to extend from the inner side of the protection box (102), and at this time, the workpiece is placed on the upper end surface of the anti-slip pad (402), and the workpiece is positioned by the positioning blocks (404) fixedly provided on two sides of the clamping platform (401); S2: Adsorption holes are provided on the upper end surfaces of the clamping platform (401) and the anti-slip pad (402), and the adsorption holes are connected to the inside of the clamping platform (401). The workpiece can be adsorbed and fixed by evacuating the inside of the clamping platform (401). A cylinder is installed at the bottom end of the clamping claw (403), so that the cylinder drives the clamping claw (403) to move downward under the support of the clamping platform (401) and presses the four sides of the workpiece, thereby effectively maintaining the accurate and stable loading of the workpiece; S3: during the resetting process of the connecting slides (204), two of the connecting slides (204) and the other two connecting slides (204) drive the workpieces to move toward the inner side of the protection box (102) to achieve stable adjustment in the Y direction; S4: starting the second transmission motor (301), so that the second transmission motor (301) drives the two connecting slide blocks (303) to be adjusted in the X direction through the second transmission screw (308) under the support of the protection box (102), and then the connecting slide blocks (303) drive the three-dimensional imaging sensor (310) and the fill light (311) to move through the Y-direction support arm (304), the connecting stand (305) and the mounting plate (307), and then, during the adjustment of the workpiece and the three-dimensional imaging sensor (310) in the Y direction and the X direction respectively, the fill light (311) enables the three-dimensional imaging sensor (310) to scan the surface of the workpiece, and then the surface of the workpiece can be inspected for flatness; S5: Both ends of the adjusting rod (207) are provided with external threads with opposite rotation directions, and the adjusting rod (207) is connected to the two transmission blocks (206) by threads, so that when the adjusting rod (207) rotates to drive the two transmission blocks (206) to separate, it is convenient to adjust the position of the transmission frame (208) along the axis of the first transmission screw (202), and at the same time, the bottom end of the locking knob (306) passes through the connecting stand (305) and contacts the connecting slide (204), and the locking knob (306) is connected to the connecting stand (305) by threads. By sliding the connecting stand (305) on the inner side of the Y-axis support arm (304) and locking it by the locking knob (306), the scanning and detection operation of workpieces of different sizes can be satisfied.
