Description
The present invention is dividing an application of Chinese patent application 01107647.X patented claim, and the original bill applying date is March 17 calendar year 2001, and denomination of invention is: optical combination assembling method.
[technical field]
The invention relates to a kind of optical combination assembling method, refer in particular to a kind of light that is installed on is passed the assemble method connect in the module, to have good relative positioning in order to the optics combination assembling quickly that receives or transmit signal and each parts of assembling back.
[background technology]
In light communication system, place light to pass to connect module and receive or transmit the light signal and realize that the optics combination of photoelectricity signal conversion is very important.Because of this optics combination is to be made of a plurality of parts, and must have accurate relative positioning between each parts, so the assembling of this optics combination is difficult.In view of this, industrial community has the multiple assembling mode of development.
The mode of thermosetting cement assembling optics combination is wherein a kind of.This optics combination comprises a supporting component and a lid, and wherein, this supporting component has one first composition surface, and this lid has one second composition surface.During assembling, earlier lid and supporting component are placed respectively on the upper and lower truing tool of a coupling board, after regulating calibration, first composition surface is contacted with second composition surface, and between two composition surfaces, put thermosetting cement, this optical group is share the anchor clamps clamping, to keep the relative positioning of supporting component and lid, then the optics combination is taken off and is positioned in the temperature control heating furnace from truing tool together with anchor clamps, through the certain hour heating both are fixed together.Yet this kind assemble method complex steps, and be not suitable for the single-mode fiber transmission system, reason is that the single-mode fiber core diameter only is 6-10 μ m, the relativity shift of assembled components 0.5 μ m promptly can cause very disadvantageous consequence, and take off the back, transport the process to it is inserted the temperature control heating furnace from truing tool together with anchor clamps in the combination of this optics, easily and other object collision and supporting component and lid position are relatively moved.In addition, exist, can occur when thermosetting cement solidifies successively, and cause this calibrated two assembly relative position generation angular deflections because of thermograde is arranged in the heating furnace.
The existing assembling mode of another kind of optics combination can be consulted United States Patent (USP) the 4th, 969, No. 702 (with reference to Fig. 1), this optics combination comprises laser diode (LD) 12, supporting component 14, lens (Lens) 16 and lid 18, wherein, this laser diode 12 is to be fixed in the supporting component 14, in order to produce the light wave of certain wavelength, these lens 16 are located on the laser diode 12 and are done suitably location, this lid 18 has a through hole 22, in order to admit the sleeve 26 of a band optical fiber 24, and this lid 18 is to make optical fiber 24 and laser diode 12 and lens 16 align the back through adjusting to be fixed on the supporting component 14 by ultraviolet freezing plastic (solidifying under the ultraviolet ray irradiation), so that the light that laser diode 12 sends is coupled in the optical fiber 24 and the transmission of realization light signal via lens 16.But, after between supporting component 14 and the lid 18 being elder generation's coating one deck ultraviolet ray freezing plastic, placing respectively on the truing tool and through adjusting aligns optical fiber 24 and laser diode 12 and lens 16, fixing by UV-irradiation again to interconnect, for making ultraviolet lighting be incident upon ultraviolet freezing plastic, at least one assembly that applies ultraviolet freezing plastic must be transparent, and must consider its profile during the design truing tool, to prevent to block ultraviolet light ultraviolet freezing plastic is solidified, so, will increase design difficulty and make the assembly selection limited.
The existing assembling mode of another optics combination can be consulted United States Patent (USP) the 5th, 073, No. 047 (with reference to Fig. 2), this optics combination comprises light source 15, fixed cover 19, housing 17 and socket 1, wherein this light source 15 is to be fixed in the fixed cover 19, the fixed cover 19 of this band light source and housing 17 be by laser dotting in both junctions and form Laser Welding (LBW) contact 16 and be fixed together (being the laser bonding mode), this housing 17 and socket 1 also are in both junctions and form Laser Welding (LBW) contact 18 and be fixed together after regulating calibration by laser dotting.But, weld fixing assembly by the laser welding mode and be necessary for metalwork, and must adopt expensive special-purpose laser welding machine to finish.
In order to reduce manufacturing cost, industrial community has the mode that adopts by the combination of Instant cement (InstantGlue) assembling optics in addition, be about to that supporting component and lid place respectively on the truing tool and through regulate calibrate after, at both surface of contact place's point Instant cement rapid solidifications both are connected, and Instant cement is to contact the rear solidifiable with water vapour, because the water vapor concentration of each point is different and wayward in the three dimensions, therefore Instant cement solidifies has successively, and cause these calibrated two assembly relative positions to be offset, significantly reduce the efficient of light coupled into optical fibres, this skew is especially showing influencing in the single-mode fiber transmission system.Still have good relative positioning if make this optical group set up each parts of dress back jointly, this assembly operation must and shake in the certain space that all is subjected to good control in humidity to be finished, and manufacturing cost is improved.
In view of this, provide a kind of optics combination assembling quickly and assemble each parts of back and have the assemble method of good relative positioning in fact for essential.
[summary of the invention]
The object of the present invention is to provide one can and assemble the optical combination assembling method that each parts of back have good relative positioning with the quick assembling of optics combination.
A kind of optical combination assembling method comprises the steps: to provide optics combination pedestal, comprises one first composition surface, and its internal fixation one photoelectric subassembly; One optics plate connector is provided, comprises one second composition surface, and be inserted with optical fiber component in the opposite end on second composition surface; One heating arrangement is provided, it comprises a heat energy emission part and a guide pipeline, this heat energy emission part is the circulating line that an inboard is evenly equipped with several gas holes, and this guide pipeline and circulating line are conducted, and this heat energy emission part is placed in a periphery on first and second composition surface; Socket is placed on the pedestal, first composition surface is contacted with second composition surface, adjust the relative position of calibration pedestal and socket, at two composition surface joint point thermosetting cements; Make the heat energy emission part of heating arrangement produce heat,, it is solidified to heat the thermosetting cement of two composition surface joints.
Compare with existing optical combination assembling method, the present invention has following remarkable result: need not move calibrated pedestal and socket thermosetting cement is solidified under the heating arrangement effect, and quick and location accurately fits together and forms the optics combination with pedestal and socket.Below in conjunction with accompanying drawing embodiments of the invention are specifically described:
