Embodiment Construction

[0035] Please also refer to Figure 2A as well as Figure 2B , which respectively show a structural block diagram and a partial structural diagram of an automatic tilt angle adjustment system used in an optical drive according to a preferred embodiment of the present invention. The optical drive 200 is, for example, an optical disc recorder, which includes a spindle motor 210 and an optical pickup head 220 . A spindle motor (Spindle Motor) 210 is used to drive an optical disk (not shown in the figure) to rotate, and the spindle motor 210 includes a rotating tray 212 for placing the optical disk. The optical pickup head 220 is slidably disposed on the first slide rail 222 and the second slide rail 224 . The first slide rail 222 has a first screw 221, and the second slide rail 224 has a second screw 223 and a third screw 225 to adjust the inclination angles of the first slide rail 222 and the second slide rail 224 by locking or loosening. , and determine the direction of the ...

Abstract

This invention relates to an automatic regulating system for tilt angles including a first, a second and a third reflection plate, a collimation unit, an image process unit and a tilt angle regulation unit, in which, the first and the second reflection plate are put on the first and second slideway, the third reflection plate is set on the rotation tray, the collimation unit provides parallel beams to the reflection plates and outputs corresponding sensing signals based on the reflected light reflected by the plates, the image process unit outputs corresponding control signals based on the sensing signals, the tilt angle regulation unit rotates the screws of the two slideways based on the control signals to regulate the shaft tilt angle of the rotary tray and the optical read head.

Description

technical field [0001] The present invention relates to an inclination automatic adjustment system and its method, and in particular to a self-learning (Self Learning) inclination automatic adjustment system and its method. Background technique [0002] Tilt adjustment between the turn table and the optical pickup head is the most important step in the assembly process of the optical drive. Generally speaking, the adjustment of the inclination angle is performed manually. Please refer to figure 1 , which shows a schematic diagram of tilt adjustment of a traditional optical drive. Such as figure 1 As shown, the optical pickup head 110 of the optical drive is mounted between the first slide rail 112 and the second slide rail 114 in a slidable manner. Therefore, by locking or loosening the screws A, B and C provided on the first slide rail 112 and the second slide rail 114, the inclination angles of the first slide rail 112 and the second slide rail 114 can be changed, and ...
