Laser automatic focusing system based on image

The application discloses laser automatic focusing system based on image. This system includes mobilizable board, has internal surface and relative surface, the board is become by the adaptation receive the biological sample on the internal surface, imaging part, imaging part enlargies the biological sample focuses on the biological sample, automatic focusing LAF equipment based on laser, automatic focusing equipment based on laser passes through the imaging part orientation the board illuminating laser beam, so that laser is followed the internal surface of board and the reflection of surface go back to pass through imaging part, the motor stator core coil winding machine comprises a driving mechanism, actuating mechanism moves towards in the z orientation and keeps away from the board removes imaging part, the camera, the camera record is followed imaging part receives the image of biological sample, a controller, the controller is confirmed based on the position on internal surface reflection's the image t
