Description
Technical field
The present invention is related to Optical devices, and in particular to the Optical devices that connection or fixation between optical module are carried out using laser welding.
Background technology
Assembling between the optical module of Optical devices generally has strict positioning requirements.The existing common practice is to use ultraviolet light bonding agent to carry out connection or fixation between optical module, but it be present.For example, it is desired to which irradiating ultraviolet light is solidified, and needs artificial dispensing to improve yield, therefore more take time and effort.Another practice is to carry out connection or fixation between optical module using laser welding, and it is more time saving, easy automation and bonding strength is stronger, but laser welding can produce stress between optical module, cause the position of optical module to offset.Therefore, later also develop a kind of practice be first using bonding agent, reuse laser welding carry out optical module between connection or fixation, such as TaiWan, China patent No. I386268, can improve laser welding and cause the problem of optical module position is offset, but more time-consuming and expend material.
The content of the invention
In view of this, the purpose of the present invention is proposing Optical devices, and connection or fixation between laser welding progress optical module is used only in it, you can so that optical module is after welding, position skew will not excessively expand.
To reach above-mentioned purpose, the present invention proposes an a kind of exemplary embodiment of Optical devices, including the first optical module with primary optic axis and the second optical module with the second optical axis.First optical module is sheathed on the second optical module.Adhesive-free between first optical module and the second optical module.First optical module coats one row laser solder joint of each formation on the opposite sides face of the second optical module.Primary optic axis and the second optical axis alignment error are not more than 0.5 micron（Micrometer, um）.
The present invention also proposes an exemplary embodiment of another Optical devices, including an at least optical unit and bearing assembly.Bearing assembly has relative first surface and second surface.Each optical unit is not more than 0.5 micron of primary optic axis and the second optical axis comprising alignment error, and is arranged at the first surface of bearing assembly.The second surface of bearing assembly shape laser solder joint in a row at the one of correspondence optical unit.
For above and other objects, features and advantages of the invention can be become apparent, preferred embodiment cited below particularly, and coordinate accompanying drawing, it is described in detail below.

Embodiment
Fig. 1 to Fig. 3 is respectively decomposition texture schematic diagram, assembly structure diagram and the cross section structure diagram of an a kind of exemplary embodiment of Optical devices.Referring to Fig. 1 to Fig. 3, Optical devices 1 include the first optical module 11 with primary optic axis and the second optical module 12 with the second optical axis.Optical module may be the luminescence component with optical axis, or lens subassembly.In the present embodiment, the first optical module 11 is lens subassembly, and it includes lens carrier 111 and the lens 112 in lens carrier 111.The primary optic axis of first optical module 11 is the optical axis of lens 112.Second optical module 12 is laser module, and it includes diode support 121 and the laser diode 122 on diode support 121.Second optical axis of the second optical module 12 is the optical axis of laser diode 122.
As shown in Figures 2 and 3, the first optical module 11 is sheathed on the second optical module 12.First optical module 11 coats one row laser solder joint 114 of each formation on the opposite sides face 113 of the second optical module 12（It may be black circular spot）, and the second optical axis alignment error of the primary optic axis of the first optical module 11 and the second optical module 12 is not more than 0.5 um, to meet the specification of optical module position positioning.In the position of laser solder joint 114, the first optical module 11 and the second optical module 12 are coupled or fixed to together as Fig. 3 signal generates melting.In addition, adhesive-free between the first optical module 11 and the second optical module 12.
Fig. 4 is the assembly structure diagram of an exemplary embodiment of another Optical devices.Fig. 4 is refer to, Optical devices 2 include at least an optical unit 21 and bearing assembly 22.Each optical unit 21 is not more than 0.5 micron of primary optic axis and the second optical axis comprising alignment error.In the present embodiment, Optical devices 2 include three optical units 21, and these three optical units 21 are respectively used to transmitting feux rouges, green glow and blue light all using the Optical devices 1 as disclosed by Fig. 2.Bearing assembly 22 has relative first surface 221 and second surface 222.Optical unit 21 is arranged at the first surface 221 of bearing assembly 22.The second surface 222 of bearing assembly 22 shape laser solder joint 223 in a row at the one of each optical unit 21 of correspondence, this row's laser solder joint 223 is likely distributed on a straight line, or is distributed in an overall trend on the irregular lines of a straight line.In the position of laser solder joint 223, optical unit 21 and bearing assembly 22 generate melting and are coupled or fixed to together.In addition, adhesive-free between optical unit 21 and bearing assembly 22.
