Through the technical scheme, when the photoresist residues need to be eliminated, the driving unit drives the roller brush 21 to be kept at the standby position, then the laser emitting mechanism emits laser to the photoresist residues on the substrate 80 to eliminate the photoresist residues, dust 90 is generated after the photoresist residues are eliminated and is attached to the substrate 80, and then the driving unit drives the roller brush 21 to move to the cleaning position to clean the dust 90 on the substrate 80, so that the surface of the substrate 80 is cleaned, and the quality of the substrate 80 is improved.
In order that the laser light emitted by the laser emitting mechanism is not affected by the roll brush 21, it is preferable that the laser emitting mechanism is configured to: the laser light is emitted to the preset position when the roll brush 21 is at the standby position, and the laser light emission is stopped when the roll brush 21 is at the cleaning position. Specifically, the repair machine may include a detection element for detecting the position of the roll brush 21, the laser emission mechanism being electrically connected to the detection element, the detection element controlling the laser emission mechanism to emit laser light when the detection element detects that the roll brush 21 is at the standby position, and the detection element controlling the laser emission mechanism to stop emitting laser light when the detection element detects that the roll brush 21 is away from the standby position. Thereby ensuring that the laser light emitted by the laser emitting mechanism is not disturbed by the roll brush 21.
It should be understood that the driving unit may be designed in various forms as long as it can move the roller brush 21 between the cleaning position and the standby position, for example, the driving unit may include a linear motor, and the roller brush 21 is mounted to a mover of the linear motor to move between the cleaning position and the standby position, and in a preferred embodiment of the present invention, the driving unit includes a rotating mechanism configured to drive the roller brush 21 to move between the cleaning position and the standby position. That is, in a preferred embodiment of the present invention, the moving trajectory of the rolling brush 21 is designed in a circular arc shape so that the rolling brush 21 swings between the cleaning position and the standby position.
In order to enable the rolling brush 21 to swing between the cleaning position and the standby position, the rotating mechanism includes a first motor 31 and a connecting rod 32, the first motor 31 is mounted on the laser emitting mechanism, one end of the connecting rod 32 is connected to a rotating shaft of the first motor 31, and the rolling brush 21 is rotatably disposed at the other end of the connecting rod 32.
