When concrete operations: first, the fixture that the first heat-conducting block 001 and the second heat-conducting block 002 are formed is establishedOn installing plate 011, then open the first heat-conducting block 001, the metal tube of needs heating is put into second and leadsIn the locating slot of hot piece 002, then first heat-conducting block 001 that closes, now, metal tube is just in time positioned at first leadsIn locating hole 401 between hot piece 001 and the second heat-conducting block 002;
Put on optical fiber and glass solder ring, adjust behind position, for example, adhesive tape for optical fiber (3M adhesive tape)Be fixed on conducting strip 004;
Then, vertical the fixture assembling (the first heat-conducting block 001 and the second heat-conducting block 002) 90 degreePut, can allow like this glass solder can evenly flow in the closed hole of metal tube;
Afterwards, first open the power supply of radiator fan 014, contribute to the radiating block 005 of cooling piece 006 belowHeat radiation, heightens refrigerating efficiency better; Open again the power supply that cooling piece 006 connects, allow it start refrigeration,And keep duty always; Then open the power supply that heating tube 003 connects, start the first heat-conducting block001 and second heat-conducting block 002 heat, make its heat up, in temperature-rise period, measure by Temperature DetectorThe temperature of metal tube, treats that its temperature reaches 370 DEG C of left and right, keeps this temperature value a period of time, makes glass welderingMaterial fusing. Now, utilize heating tube heating heat-conducting block be then delivered to metal tube again heat conduction to scolder,Make solder fusing, although the temperature of heated metal tube reaches the high temperature of 370 DEG C,, due to refrigerationThe effect of sheet 006, has realized the cooling of the optical fiber to stretching out metal tube two ends, can protect well lightFine coat is not burned.
Until glass solder melts completely, just can close heating tube power supply, wait metal tube temperature to normal temperatureAfter close again the power supply of the power supply and blower 014 of cooling piece 006, fixture is kept flat, then takes out and weldGood metal tube.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field can be realized or useThe present invention. To be aobvious and easy for those skilled in the art to the multiple amendment of these embodimentSee, General Principle as defined herein can be in the situation that not departing from the spirit or scope of the present invention,Realize in other embodiments. Therefore, the present invention will can not be restricted to these embodiment shown in this article,But to meet the widest scope consistent with principle disclosed herein and features of novelty.
