Abstract
The invention provides a three-dimensional fixing method of a micro-naked coupling lens, comprising the steps: attaching an LD (laser diode) chip on a top supporting surface on a step seat, wherein the front side of the step seat is provided with a bottom supporting surface which is lower than and parallel to the top supporting surface; utilizing a suction pipe type clamp to hang the micro-naked coupling lens above the bottom supporting surface and adjusting the position of the micro-naked coupling lens by the suction pipe type clamp so as to lead the coupling of the micro-naked coupling lens and the LD chip to be in place; utilizing a CCD (charged coupled device) camera to measure the height of a gap between the bottom surface and the bottom supporting surface of the micro-naked coupling lens; utilizing the suction pipe type clamp to move the micro-naked coupling lens upwards, then selecting and putting a gasket on the bottom supporting surface, and moving the micro-naked coupling lens downwards to lead the micro-naked coupling lens to be located on the gasket, wherein the thickness of the gasket is consistent to the height of the measured gap; and utilizing the conventional sticking mode to fix the micro-naked coupling lens and the gasket. The three-dimensional fixing method has the advantages that the operation is simple and convenient, the control is easy, the error is less, the optical coupling efficiency is high, the time and the labor are saved, and simultaneously the repairability is achieved.
Description
Technical field
The present invention relates to a kind of three-dimensional fixation method of three-dimensional fixation method, particularly a kind of small naked coupled lens of lens.
Background technology
The size of photoelectric device is more and more littler in recent years, and in order to reduce volume, coupled lens is generally all used small naked lens.But naked lens are not owing to there is metallic sheath not to be fixed on the metal support with YAG laser.The accent core of small naked lens up to now all is with passive (Passive) core regulating method with fixing, promptly there is the 1-2 micron to have to stick the LD chip with the precision of sub-micron with mechanical arm earlier on the Si Micro Bench of V groove and then small naked lens is placed on the suitable position of V groove, fix it with scolding tin or UV glue at last in machining precision.Accent core and fixing means not only need putting together machines of costliness and have the Si Micro Bench of V groove, and comprehensively transfer the core precision not high.General LD chip just has several microns in the error of paster operation, if the height error of Si Micro Bench has 2 microns, V groove error has 1 micron, and small in the worst case naked lens can be near 10 microns in the error of height.10 microns accent core error can cause enough big light coupling loss.Passive in addition (Passive) core regulating method can not the The real time measure coupling efficiency.Find can't repair when light coupling loss is excessive in case assembling finishes, this will directly have influence on the yield of assembling.
Summary of the invention
The purpose of this invention is to provide a kind of easy and simple to handle, time saving and energy saving, error is little, coupling efficiency is high, repair the three-dimensional fixation method of small naked coupled lens easily, overcomes the deficiencies in the prior art.
The three-dimensional fixation method of small naked coupled lens of the present invention, step is as follows:
A, the LD chip is attached on the top support surface of step seat top, there is the bottom support face that is lower than and is parallel to top support surface the front side of described step seat;
B, utilize the hydrocone type anchor clamps that small naked coupled lens is hung on the top of described bottom support face, and adjust the position of small naked coupled lens, the coupling of small naked coupled lens and LD chip is put in place by the hydrocone type anchor clamps;
C, utilize the CCD camera to measure the bottom surface of small naked coupled lens and the slit height between the bottom support face;
D, utilize and move small naked coupled lens on the hydrocone type anchor clamps, select pad then and pad is placed on the bottom support face, move down small naked coupled lens and make it to be seated on the pad, the thickness of described pad is consistent with institute joint measurement crack height;
E, utilize fixing small naked coupled lens of conventional bonding method and pad.
The three-dimensional fixation method of small naked coupled lens of the present invention, easy and simple to handle, good control, error is little, and the coupling efficiency height is time saving and energy saving, has recoverable advantage simultaneously.
Description of drawings
Fig. 1 is the synoptic diagram of embodiments of the invention;
Fig. 2 is that synoptic diagram is looked on a left side shown in Figure 1.
Embodiment
As shown in Figure 1, 2: 1 is the step seat, and the back side top of step seat 1 has top support surface 6, at the bottom of the front side of step seat 1 in and be parallel to the bottom support face 5 of top support surface 6.
Step of the present invention is as follows:
A, LD chip 2 is attached on the step seat 1 top top support surface 6, there is the bottom support face 5 that is lower than and is parallel to top support surface 6 front side of described step seat 1;
B, utilize the hydrocone type anchor clamps that small naked coupled lens 3 is hung on the top of described bottom support face 5, and adjust the position of small naked coupled lens 3, small naked coupled lens 3 and 2 couplings of LD chip are put in place by the hydrocone type anchor clamps;
C, utilize the CCD camera to measure the bottom surface of small naked coupled lens 3 and the slit height between the bottom support face 5 from the side;
D, utilize and move small naked coupled lens 3 on the hydrocone type anchor clamps, select pad 4 then and pad 4 is placed on the bottom support face 5, move down small naked coupled lens 3 and make it to be seated on the pad 4, the thickness of described pad 4 is consistent with institute joint measurement crack height;
E, utilize fixing small naked coupled lens 3 of conventional bonding method and pad 4.
Further specify said method below:
As long as between the top support surface 6 of step seat 1 and the bottom support face 5 precision of height dimension have 10 microns just enough, so component costs is lower.LD chip 2 be attached to step seat 1 top support surface 6 central authorities and near preceding edge because the error that paster causes, the luminescent center of LD chip 2 from the absolute error of the height of bottom support face 5 can not surpass+/-20 microns.So as L is the nominal altitude of the luminescent center of LD chip 2 from bottom support face 5, then the luminescent center of LD chip 2 fixes on the L-20 micron between the L+20 micron from the true altitude one of bottom support face 5.
