s3: the bar code gun (51) scans the code; the control system drives a sliding part (412) to move on a sliding rail (411) through a driving air cylinder (413), the driving part drives an HDD magnetic head (8) to move to the side face of a bar code gun (51), then the bar code on the HDD magnetic head (8) is scanned through the bar code gun (51), and code scanning information is fed back to the control system;
s4: the HDD head (8) is moved to a dismantling station; after the HDD magnetic head (8) finishes scanning codes, the control system drives the sliding piece (412) through the driving cylinder (413) and drives the HDD magnetic head (8) to move to the dismantling station;
s5: data comparison and identification; the control system is used for corresponding the code scanning data and the pre-led repair data one by one, and sending an instruction and controlling the servo positioning mechanism in the horizontal direction according to the comparison result, so that the first slider (522) is driven to move in the horizontal direction and move to the position above the dismantling station;
s6: detecting a multidirectional visual compensation error mechanism; starting a multidirectional visual compensation error mechanism to position from vision, and sending detected data to a control system;
s7: the dismantling mechanism moves; the control system controls the servo positioning mechanism in the vertical direction, drives the second slider (531) to move in the vertical direction, and continuously adjusts the position of the dismantling mechanism according to the detection data of the multi-azimuth visual compensation error mechanism until the dismantling mechanism is positioned at a proper station;
s8: a dismantling blade (32) for dismantling the HDD head (8); when the dismantling mechanism is positioned at a proper position of the dismantling station, the control system controls the dismantling knife (32) to dismantle the HDD magnetic head (8) to be dismantled, so that the dismantling of the HDD magnetic head (8) to be repaired is completed.
