Description
Technical field
This utility model relates to optical communications industry, particularly relates to the production technology of TOSA.
Background technology
Along with the fast development of optical communications industry, it is more and more higher that the integrated level of chip is done by chip of laser producer, that
How the COC(Chip On Carrier of high integration) high-precision assemble become optical device producer need solve
Significant problem.TOSA(Transmitter Optical Subassembly, light emission secondary module) common packing forms has
Two kinds: TO encapsulation and BOX(housing) encapsulation.It is directed to TO encapsulation, need to be that components and parts are mounted on a TO base during attachment,
Implement and be all relatively easy to, and had a lot of automation equipment can complete this kind of encapsulation at present, but shortcoming
It is that the speed can accomplished at present is the highest, so needing for selecting BOX encapsulation for some two-forty devices.BOX encapsulates, also
Claim deep chamber to encapsulate, no matter will be better than TO encapsulation in terms of transfer rate or heat radiation etc., but owing to attachment is in a space
Completing in the least housing, its attachment difficulty encapsulates much larger than TO.
Summary of the invention
For solving the problem that prior art exists, the utility model proposes a kind of COC mounting system being applicable to TOSA,
This system can complete the error high accuracy attachment less than ± 0.02mm in the small space of 4.5mm*4.4mm*4.0mm.
For achieving the above object, the technical solution adopted in the utility model is: a kind of COC being applicable to TOSA mounts system
System, including main body frame, CCD camera system and Precision trimming system, main body frame is made up of support and base, and CCD images system
System is fixed on support, and Precision trimming system is arranged on base, and Precision trimming system is made up of Precision trimming platform and fixture, folder
Tool is arranged on Precision trimming platform and is positioned at the underface of CCD camera system.
Described CCD camera system is made up of photographic head, display and cross hairs generator, cross hairs generator and photographic head
Electrical connection, photographic head electrically connects with display.
Described Precision trimming platform includes that X is to micromatic setting, Y-direction micromatic setting and rotating fine-regulating device.
Described X is 0.005mm to the precision of micromatic setting, and the precision of Y-direction micromatic setting is 0.005mm, and rotary fine adjustment fills
The precision put is 1 °.
This utility model, for the laser instrument of high speed BOX encapsulation, needs the TOSA device of mount components to be placed on fixture, behaviour
Make the personnel position by the CCD camera system monitoring TOSA device above fixture, and carry out position by precision micrometer adjustable device
Adjust, such that it is able to accurately will be mounted on the reference position in housing by patch element.This utility model has simple in construction, just
Advantage in operation, it is possible to achieve complete error in the small space of 4.5mm*4.4mm*4.0mm less than ± 0.02mm's
High accuracy attachment.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in detail.
A kind of COC mounting system being applicable to TOSA as shown in Figure 1, 2, including main body frame, CCD camera system 3 and
Precision trimming system, main body frame is made up of support 1 and base 2, and its Main Function is firm for whole system offer one
Platform；CCD camera system 3 is fixed on support 1, and CCD camera system 3 is by photographic head, display 11 and cross hairs generator 10
Composition, cross hairs generator 10 electrically connects with photographic head, and photographic head electrically connects with display 11.Precision trimming system is arranged at the end
On seat 2, Precision trimming system is made up of Precision trimming platform 4 and fixture 5, and fixture 5 is arranged on Precision trimming platform 4 and is positioned at CCD
The underface of camera system 3, fixture 5 is used for clamping TOSA device 6 to be mounted, Precision trimming platform 4 include X to micromatic setting 7,
Y-direction micromatic setting 8 and rotating fine-regulating device 9, the precision that wherein X fills 7 to fine setting is 0.005mm, the precision of Y-direction micromatic setting 8
For 0.005mm, the precision of rotating fine-regulating device 9 is 1 °, and its three coordinates regulation to make laser instrument shell alignment fiducials line.
First have to when using this utility model system regulate X to micromatic setting 7, Y-direction micromatic setting 8 and rotating fine-regulating device
9 so that alignd with attachment datum line by patch device, then with tweezers, the COC 13 pasted is put in shell 12, gently adjust COC
13 positions make it be directed at spacing cross line and complete attachment.Use this utility model attachment after by patch element COC 13 at shell 12
Attachment deviation on interior XY direction is being not more than ± 0.02mm.Table one gives 11 measured under tool microscope after attachment
The X of chip in device, Y-direction measured value, wherein, as Fig. 3, X to reference value be a=1.58mm, the reference value of Y-direction is b=
1.4mm。
Table one: the X of COC after attachment, Y-direction measured value
From table one, this utility model is used to carry out the chip attachment of BOX encapsulation, the attachment error of chip is not more than ±
0.02mm, it is possible to reach intended required precision.
