The method of the manufacture joints of optical fibre lock pin according to the first embodiment of the present invention is described referring to Fig. 3 to Fig. 9.
As shown in Figure 4, by stationary installation 200, connector ferrule 100 is fixed in advance, then, utilize the end face of the optical recognition system such as video camera (not shown) identification connector lock pin 100, such as, as shown in Figure 5, the determined center C1 of outline 101, the center C2 of endoporus 102 and the outside diameter of connector ferrule 100 of connector ferrule 100 can be identified.Certainly, also the determined center C1 of outline 101 of connector ferrule 100 can only be identified, or the center C2 of the determined center C1 of the outline 101 only identifying connector ferrule 100 and endoporus 102, or the outside diameter of the determined center C1 of the outline 101 only identifying connector ferrule 100 and connector ferrule 100.
At the determined center C1 of the outline identifying connector ferrule 100, after the center C2 of endoporus 102 and the outside diameter of connector ferrule 100, if needed, stationary installation 200 can be unclamped, and utilize lock pin position regulating system (not shown) that the center C1 of lock pin 100 is adjusted to precalculated position, such as, as shown in Figure 5, the center C2 of the center C1 and endoporus 102 that are adjusted to lock pin 100 is on the vertical straight line of same, and makes the center C2 of endoporus 102 be positioned at the below of the center C1 of lock pin 100.
After the center C1 of lock pin 100 is adjusted to precalculated position, stationary installation 200 again can be utilized to fix lock pin 100, thus the center C1 of lock pin 100 is held in a predetermined position place.Afterwards, as shown in Figure 6, can optical fiber 300 be inserted in the endoporus 102 of lock pin 100, such as, can insert by mechanical arm or manually.
After optical fiber 300 inserts in the endoporus 102 of lock pin 100, the diameter (or being called the diameter of optical fiber 300) of the attached layer of bag of the center C3 of the attached layer of bag of recognition system identification optical fiber 300, the center C4 of the fibre core of optical fiber 300 and optical fiber 300 can be used.Like this, the center C3 of the attached layer of bag of optical fiber 300, the position relationship between the center C4 of the fibre core of optical fiber 300 and the center C1 of the lock pin 100 and center C2 of endoporus 102 can just be obtained, as shown in Figure 7.Certainly, also the center C4 of the fibre core of optical fiber 300 can only be identified, or only identify the center C4 of fibre core of the optical fiber 300 and center C3 of the attached layer of bag of optical fiber 300, or only identify the center C4 of fibre core of optical fiber 300 and the diameter of the attached layer of bag of optical fiber 300.
Because the deviation between the center C4 of the fibre core of optical fiber 300 and the center C1 of lock pin 100 is larger, as shown in Figure 7, therefore, need to use fiber position regulating system 400 (as shown in Figure 8) to regulate the position of optical fiber 300, the center C4 of the fibre core of optical fiber 300 is aimed at the center C1 of lock pin 100, namely, make difference between the center C4 of the fibre core of the optical fiber 300 and center C1 of lock pin 100 in preset range, this preset range can be-0.3 μm to 0.3 μm, preferably, this preset range can be-0.1 μm to 0.1 μm, more preferably, this preset range can be-0.01 μm to 0.01 μm.Note that this preset range can be determined by the actual precision that will reach.
As shown in Figure 7, the center C4 of the fibre core of optical fiber 300 be moved to and aim at the center C1 of lock pin 100, fiber position regulating system 400 at least needs to move along orthogonal both direction, such as, and illustrated horizontal direction and vertical direction.And, if needed, fiber position regulating system 400 also needs to rotate optical fiber 300, to regulate the center C4 of the fibre core of optical fiber 300 relative to the position angle of the center C3 of the attached layer of the bag of optical fiber 300, such as, the center C3 of the attached layer of bag of the center C4 of the fibre core of optical fiber 300 and optical fiber 300 is positioned on same vertical straight line, and makes the center C4 of the fibre core of optical fiber 300 be positioned at the top of the center C3 of the attached layer of bag of optical fiber 300.
The schematic diagram of the center C4 of the fibre core of the optical fiber 300 after adjustment, the center C3 of the attached layer of bag, the center C1 of connector ferrule 100 of optical fiber 300 and the center C2 of endoporus 102 is shown shown in Fig. 9.After adjustment, the distance between the center C4 of the fibre core of the optical fiber 300 and center C1 of connector ferrule 100 is less than or equal to 0.3 μm, thus achieves aiming at of the center C4 of the fibre core of optical fiber 300 and the center C1 of connector ferrule 100.
After the aiming at of the center C4 of the fibre core of optical fiber 300 and the center C1 of connector ferrule 100, can the hardening agent at rapid curing connector ferrule 100 top, then connector ferrule 100 is taken off from stationary installation 200 release together with optical fiber 300, and be put into solidification case finish all solidstate, thus be fixed in the endoporus 102 of lock pin 100 by optical fiber 300 by hardening agent, thus the relative position between the center C4 of the fibre core of the optical fiber 300 and center C1 of lock pin 100 is remained unchanged.
Described hardening agent can be filled in the endoporus 102 of lock pin 100 before or after the endoporus 102 that optical fiber 300 inserts lock pin 100.If be filled into insert the endoporus 102 of lock pin 100 at optical fiber 300 before in the endoporus 102 of lock pin 100, then after optical fiber 300 inserts the endoporus 102 of lock pin 100, also need to carry out cleaning to optical fiber 300 by by the end of the holder of fiber position regulating system 400.
Aforementioned curing agent can be filled in the endoporus 102 of lock pin 100 by capillary effect or vacuum suction mode.
In order to prevent hardening agent from adhering on the fixture of fiber position regulating system 400, in one embodiment of the invention, can make to be separated by between the end face of the end face of the fixture of fiber position regulating system 400 and lock pin 100 spacing of 0.5mm to 1.0mm.
