Embodiment Construction

[0043] In order to achieve the above object, the present invention adopts the technical means and its effects, hereby give preferred embodiments, and illustrate as follows in conjunction with the accompanying drawings.

[0044] Please refer to figure 2 , is an exploded structure on the back of the movement 20 with the splash-proof device of the first embodiment of the present invention. The movement 20 includes a body 21 , a transmission device 22 , a reading head 23 , and a splash-proof device 24 . The body 21 of the movement 20 is basically a polygonal plate, and one end is supported by a circuit board 25 to fix a spindle motor 26 . The upper surface of the main body 21 is covered with a protective cover 27 , and the protective cover 27 defines a long slot 28 along the radial direction of the spindle motor 26 and the long axis of the main body 21 .

[0045] The transmission device 22 is disposed on both sides of the movement 20 and mainly includes a transmission motor 30 ...

Abstract

The invention discloses a movement with an anti-splash device. One end of a main body is fixed with a spindle motor and the upper surface of the main body is covered with a protective cover. A transmission device rotates a driving screw through a drive motor; two guide rods which are parallel to the driving screw are respectively arranged on the two sides of the main body; the two sides of a read head is sleeved on the two guide rods, wherein one side of the read head is driven to slide along the two guide rods by the driving screw; and an anti-splash paster of the anti-splash device is arranged on the bottom surface of the protective cover between the two guide rods and the protective cover to block lubricating oil splashed from the two guide rods.

Description

technical field [0001] The invention relates to a core of an optical disc drive, in particular to a splash prevention device used to deal with the splash pollution of lubricating oil formed by the high-speed rotating transmission device in the transmission device of the reading head of the core. Background technique [0002] With the demand for high-resolution images and the rapid increase in the capacity of Blu-ray discs, the optical disc drive needs to move the reading head at a faster speed, so that it can search and read all the information along the radial direction of the high-speed rotating disc in a short time. The information on the CD-ROM is required. [0003] Such as figure 1 Shown is a schematic diagram of the internal structure and operation of the optical disc drive 1 in the background technology. Taking the slot-in optical disk drive 1 as an example, the hollow casing 2 contains a core 3 inside. The core 3 is provided with a spindle motor 4 for rotating the...
