The method according to any one of claims 1 to 6, wherein the method is characterized by: S1, the driving chain conveying line (2) is driven to make the tray device (4) transported to the end of the turnover machine gantry (3), the laser positioner (404) on the tray device (4) alarms, and a plurality of plug valves (6) on the tray device (4) are distributed equidistantly and cross each other; S2, a coordinate system is established: the X-axis crossbar (301) is taken as the horizontal coordinate, the Y-axis sliding plate (304) is taken as the vertical coordinate, the Z-axis vertical plate (303) is taken as the height coordinate, the first motor (3013), the second motor (3043) and the lifting hydraulic cylinder (307) of the driving turnover machine gantry (3) are driven to make the driving shaft (20) of the turnover mechanism (5) coaxial with the plug valve (6) at the top, and the position is taken as the coordinate base point; S3, the turnover mechanism (5) holds the plug valve (6): the first motor (3013), the second motor (3043) and the lifting hydraulic cylinder (307) are driven to make the rotating support (10) located at the two ends of the plug valve (6), the hydraulic cylinder (12) is driven, and when the travel switch (16) alarms, the driving of the hydraulic cylinder (12) is stopped to make the rotating support (10) clamp the plug valve (6) at the two ends; S4, the turnover mechanism (5) clamps the plug valve (6): the clamping motor (2105) is driven to make the clamp (21) clamp the plug valve (6); S5, the plug valve (6) is turned over: the lifting hydraulic cylinder (307) is driven to move upward by a certain position, the turnover motor (14) is driven to rotate to make the plug valve (6) turned over by 180 degrees, the turnover motor (14) is self-locked, and the lifting hydraulic cylinder (307) is moved downward to the original position; S6, the turnover mechanism (5) is released: the clamping motor (2105) is driven to make the clamp (21) loose, and the hydraulic cylinder (12) is driven to make the rotating support (10) loose. S7, repeat S3-S6, Y-axis slide plate (304) in the x-axis direction from one end to the other end, Z-axis vertical plate (303) in the y-axis direction reciprocating, the turnover mechanism (5) in the Z-axis direction, the remaining turn valve (6) on the tray device (4) to complete the turnover process, the turnover mechanism (5) reset back to the coordinate origin, waiting for the next tray device (4) to turn over the work.
