S2, pre-fixing the plates: four corner parts of the plate (8) are pre-fixed on four support plates (44) through a pre-fixing device (45); the middle parts of the front side and the rear side of the plate are respectively pre-fixed on the two auxiliary supporting mechanisms (7) through the two auxiliary supporting mechanisms (7);

S3, placing the frame: first, the first working ends (431) of all the first clamping mechanisms (43) are withdrawn out of the frame placing groove (42); the lower ends of the four frames (9) are respectively placed in the frame placing grooves (42) of the four clamping and positioning devices (4), namely, one ends of two adjacent frames (9) are respectively placed in the frame placing grooves (42) on one clamping and positioning device (4) correspondingly, so that one ends of the two adjacent frames (9) are respectively abutted against two mutually perpendicular guide surfaces (47) of the right-angle positioning block (46); the lower ends of the middle parts of the frames (9) positioned at the front side and the rear side are placed in auxiliary frame placing grooves (73) on the two auxiliary supporting mechanisms (7), after the frames (9) are placed in, the frames (9) are pushed inwards, so that the plate (8) exposed out of the upper parts of the frame placing grooves (42) is clamped with the clamping grooves (92) of the frames (9);

S4, frame positioning: two first clamping mechanisms (43) on each clamping and positioning device (4) extend into the frame placing grooves (42) respectively, one end of each adjacent two frames (9) moves towards the plate (8) along the two guide surfaces (47) respectively, one end of each adjacent two frames (9) is attached when one end of each adjacent two frames (9) moves to the joint of the two guide surfaces (47) respectively, and one end of each adjacent two frames (9) is abutted against the outer wall of the plate (8) respectively; the second working end (481) on the second clamping mechanism (48) stretches into the frame placing groove (42) and laterally compresses the joint of one ends of the two adjacent frames (9), and the frame corner part compressing mechanism (49) compresses the joint of one ends of the two adjacent frames (9) after compressing and positioning downwards; the four frames (9) are propped against the peripheral wall of the plate (8) in the same way;

S5, assembling the plate and the frame: the first screw assembly (62) and the second screw assembly (63) on the screw mechanism (6) are used for simultaneously carrying out automatic screw processing on the joint of the peripheral frame (9) and the plate (8), and when screws are driven on the frames (9) on the front side and the rear side, an auxiliary supporting suction rod (753) on the auxiliary supporting mechanism (7) is loosened to be far away from the plate (8); the auxiliary clamping cylinder (72) is withdrawn from the auxiliary frame placing groove (73), the auxiliary supporting mechanism (7) is moved to a corresponding position below the screw driving mechanism (6) and used for supporting the plate (8) and the frame (9), and positioning adjustment of the corresponding position is carried out along with the movement of the screw driving mechanism (6), so that the auxiliary supporting mechanism (7) is always positioned at the corresponding position below the screw driving mechanism (6); the two ends of the centering support mechanism (5) also play a role in supporting the middle positions of the left side and the right side of the plate (8) when screws are driven; finally, the frame (9) and the plate (8) are assembled.
