Suction type optical disc drive

Abstract

The invention discloses a suction type optical disc drive. A sliding piece is driven by a power unit to drive a driving rod to rotate a disc-taking guiding rod to take a disc; a substrate is covered on a mainboard on the back side of a housing; the middle part of a first transmission rod is pivoted in the centre of the substrate; one end of the first transmission rod is drawn by the sliding piece; the first transmission rod is provided with a traction groove to drive a right positioning rod; the other end of the first transmission rod drives a second transmission rod which is pivoted on the substrate; the second transmission rod is fixed at one end of a returning spring and drives a disc-returning guiding rod which is pivoted on the substrate; a cam is arranged at the periphery of one end of the disc-returning guiding rod to drive a left positioning rod, is limited by a positioning spring, and approaches to the side of the housing so as to expose a gap on the back side of the substrate. By arranging the left and right positioning rods symmetrically and separately on the two sides of the disc-returning guiding rod, reducing the moving ranges of the left and right positioning rods and applying force with the disc-taking guiding rod symmetrically, the optical disc positioning guidance is facilitated.

Description

technical field [0001] The invention relates to an optical disc drive for reading and writing optical disc data, in particular to a slot-in optical disc drive for guiding and driving the optical disc into or out of the optical disc drive. Background technique [0002] Generally, there are mainly two types of disc loading methods for optical disc drives: Tray Type and Slot-in Type. A tray-type optical disc drive utilizes a slot on a tray to carry optical discs, which are pushed in or out of the optical disc drive to allow the optical discs to be positioned or ejected. As for the slot-in type CD drive, as long as the CD is directly inserted into the inlet and outlet, the CD can be automatically pushed in through the advancing and retreating mechanism, and the CD can be guided to the position. development trend. [0003] Such as figure 1 As shown, it is the background technology of China Taiwan Publication No. 200805260 "Slot-in Disc Device" patent case, in which a core 11 i...

Problems solved by technology

[0005] However, when the advancing unit 15 pushes the optical disc 16, the contacted peripheral edge is more biased toward the ejecting unit 17, and cannot apply force symmetrically between the ejecting unit 17 and the positioning unit 19, which will easily cause the central hole 20 of the optical disc 16 to be out of position. Aligning the spindle motor 12

In addition, the connecting rods of the ejection unit 17 and the positioning unit 19 are moving up and down the base plate 18, and the opening 23 can only be dug in a limited space outside the moving range of the ejection unit 17 and the positioning unit 19, and it is often impossible to align the main board 22. For the test points and maintenance positions of electronic components, the slot-in optical disk drive 10 must be disassembled to test and repair smoothly, which increases the difficulty of testing and maintenance operations

Moreover, the base plate 18 must also reserve an appropriate height from the main board 22 for setting higher electronic parts, which is not conducive to the thinning of the slot-in optical disc drive 10.

In addition, the heat generated by the electronic components of the main board 22 is the main source of temperature rise in the slot-in optical disc drive 10. The main board 22 is covered by the base plate 18, and sufficient heat dissipation cannot be achieved only with limited openings. electronic component life, and is detrimental to the operation of the slot-in disc drive 10

Therefore, the slot-in optical disc drive of the background technology still has problems to be solved urgently in terms of the mechanism and configuration of advancing and retreating discs.
