Dress, this kind of mounting structure has the drawback that and is easily damaged light-emitting component or pedestal, and occur installing bad after disassemble repairing
Difficulty, causes material scrap.It is another kind of as, as a example by Fig. 8 and Fig. 9, being first light-emitting component 28 to be arranged in a fixed mount 27,
Again fixed mount 27 assembly installing optical element is installed in the pedestal 12 of optical pick-up, although this kind of mounting structure from
Can realize disassembling repairing to a certain extent, but make installation method become complicated, the material of use is consequently increased.
Utility model content
The problems referred to above existed for prior art, the purpose of this utility model is light-emitting component in a kind of optical pickup head
Installation accuracy is high, the mounting structure of easy accessibility.
For achieving the above object, light-emitting component during this utility model adopts the following technical scheme that a kind of optical pickup head
Mounting structure, including pedestal, described pedestal has the containing tank for placing light-emitting component, the shape of containing tank and luminescence unit
The profile mounting structure of part matches, and containing tank and placement light-emitting component matched in clearance within it；Described light-emitting component
It is provided with viscose glue between lateral surface with the medial surface of corresponding containing tank, makes light-emitting component be bonded in containing tank.
As optimization, described pedestal uses one resin material to make.
As optimization, the bottom of described containing tank has glue filling trough.
Relative to prior art, this utility model has the advantage that the mounting structure that this utility model provides is simple, both
The installation accuracy of light-emitting component can be met, mounting or dismounting can be facilitated again, and improve repairing, reduce in process of producing product because of luminescence
Bad being difficult to of element disassembles the product rejection repaired and cause.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Seeing Fig. 1 and Fig. 2, the mounting structure of light-emitting component in a kind of optical pickup head, including using one resin material
The pedestal 12 made, described pedestal 12 has the containing tank 12d for placing light-emitting component 28, the shape of containing tank 12d with
The profile mounting structure of light-emitting component 28 matches, and containing tank 12d with place light-emitting component 28 matched in clearance within it, i.e.
Containing tank 12d is slightly larger in dimension than light-emitting component 28；The medial surface of the lateral surface of light-emitting component 28 and corresponding containing tank 12d it
Between be provided with viscose glue, make light-emitting component 28 be bonded in containing tank 12d.
As optimization, the bottom of described containing tank 12d also has glue filling trough.To the lateral surface of light-emitting component 28 with corresponding
Containing tank 12d medial surface between during encapsulating, part glue may flow into containing tank owing to failing to solidify in time
The bottom of 12d, glue filling trough is for collecting the glue bottom these inflows.
In this utility model optical pickup head, the installation process of the mounting structure of light-emitting component is as follows:
In optical pickup head unit 10 in the containing tank 12d structure of pedestal 12, there are three positioning reference plane is installed, respectively
Be the first positioning reference plane 12a, the second positioning reference plane 12b and the 3rd positioning reference plane 12c.Light-emitting component 28 and pedestal 12
When containing tank 12d installs, it is three positioning reference planes that three installed surfaces of light-emitting component 28 are conformed to containing tank, i.e.
The first positioning reference plane 12a of the first installed surface 28a laminating containing tank 12d of light-emitting component 28, the second peace of light-emitting component 28
The second positioning reference plane 12b of dress face 28b laminating containing tank 12d, the 3rd installed surface 28c laminating containing tank of light-emitting component 28
The 3rd positioning reference plane 12c of 12d.
Further, after light-emitting component 28 installs laminating with containing tank 12d, use appropriate glue by light-emitting component 28
The first positioning reference plane 12a of the first installed surface 28a and containing tank 12d, the second installed surface 28b and containing tank of light-emitting component 28
The second positioning reference plane 12b of 12d and the 3rd positioning datum of the 3rd installed surface 28c and containing tank 12d of light-emitting component 28
Face 12c is bonding, thus is fixed in the containing tank 12d of pedestal 12 in optical pickup head unit 10 by light-emitting component 28.
Process of producing product occurs that light-emitting component 28 is disassembled repairing by bad needs for convenience, the fixing glue of use
Water, is easier to be cut off.
Being based on light-emitting component 28 and take loose formula formula with the mounting structure of containing tank 12d, mounting structure is simple, can
Meet the installation accuracy of light-emitting component 28, mounting or dismounting can be facilitated again, and improve repairing, reduce in process of producing product because of luminescence
Bad being difficult to of element 28 disassembles the product rejection repaired and cause.
