s1: the liquid crystal panel with poor alignment is conveyed into the machine body outer cover (2) through the conveying support (3), and specifically, the liquid crystal panel is conveyed towards the direction of the machine body outer cover (2) by driving a first conveying roller shaft (3-2) on a first support (3-1) to rotate under the driving of an external driving motor;
s2: the liquid crystal panel conveyed by the first conveying roller shaft (3-2) is arranged at the top of the telescopic block (12-2), the telescopic block (12-2) is pressed downwards under the action of the touch control cylinder (25) to move downwards in the fixed seat (12-1), the telescopic block (12-2) drives the touch control block (17) on the telescopic block to be in contact with the touch control switch (16) in the downward moving process, at the moment, the electromagnet (13) at the top of the telescopic block (12-2) is electrified to generate magnetism, so that the attraction iron column (14) on the fixed block (12-5) is attracted, the attraction iron column (14) is attracted to the top of the liquid crystal panel, and the liquid crystal panel is clamped and fixed;
s3: at the moment, the longitudinal linear motor (5) can drive the longitudinal mounting plate (6) to move, the longitudinal mounting plate (6) further drives the transverse linear motor (7) to move, and the transverse linear motor (7) can drive the transverse mounting plate (8) to move, so that the positions of the workbench (9) and the hot air gun (10) on the workbench are adjusted, and the position with poor alignment on the liquid crystal panel is repaired by the hot air gun (10);
s4: touch-control cylinder (25) is at in-process electro-magnet (13) outage that resets, attracts iron column (14) and separates with liquid crystal display panel, and liquid crystal display panel after hot-blast rifle (10) is restoreed can pass through transmission roller group (18) and carry down, specifically the transmission roller is carried liquid crystal display panel to arranging on material support (4) when rotating, utilizes the second on arranging material support (4) to carry roller (4-3) and carries liquid crystal display panel away, and in addition, accessible air spring (19) promote second support (4-1) relative rotation, carry liquid crystal display panel away.
