Abstract:
An adjusting mechanism of a guide rod of an optical pick-up in an optical disk drive, including an optical disk drive chassis, a substrate of an optical pick-up module, the optical pick-up, guide rods for supporting the optical pickup, a fixture of the optical pick-up module, and a fixing press of the guide rod of the optical pick-up, wherein open-mode suspenders at the both sides of the optical pick-up and bearings is penetrated by the guide rods for suspension, and it is characterized in that:the center of the substrate of the optical pick-up module disposes two support plates and fixtures of the guide rod, therefore, the two sides of the guide rod are able to span between the support plate and the fixture of the guide rod; the fixture of the guide rod dispose a plate, and the altitude of the guide rod adjusted by an adjusting screw penetrating in a screw hole in the center of the plate; the fixing press of the guide rod of the optical pick-up is fixed by screws on the substrate, and there are pressing plates on the other end of the fixture; the pressing plates are bent to form an elbow, thereby pressing down one end of the guide rods; the rear end of the fixture of the optical pick-up module is fixed to a platform of the optical disk drive chassis to suspend the optical pick-up module and reduce the vibration; the both sides of the front end are forming an extending elastic pressing plate respectively, and the elastic pressing plate form the elbow to press and constrain the other end of the guide rod; the two sides of the guide rods of the optical pick-up are supported by the support plate, and the altitude is adjusted by the screw, the upper portion is pressed by the pressing plate with suitable elasticity to press and constrain the guide rods, and suspend the optical pick-up module.
