It sets, it can be between 0.5 millimeter to 0.125 millimeter.
Laser luminescence diode can be used in light emitting module 3, and light emitting semiconductor device also can be used certainly, also can be real
Existing this case purpose, lens 4 can be arranged in globular glass lens, certainly also can be in elliptoid lens or other conventional shapes
Lens setting, can be configured according to optical path demands at different levels.
The production method embodiment of mode of laser group:
The step of assembling to mode of laser group is told about below, and production method includes:
Firstly, lens 4 are entered to from the first mounting hole 21 and are installed to the second mounting hole 22,
Then, light emitting module 3 is fixedly mounted in the first mounting hole 21, specifically can be used optical cement and using step surface into
Row is fixedly mounted, and after light emitting module 3 is fixed, the output end face and lens 4 of light emitting module 3 are adjacent, the other side of lens 4 and the conical surface
221 is adjacent, i.e., lens 4 are gripped by light emitting module 3 and the second mounting hole 22,
Then, the first end of optical fiber 1 is accessed into detector,
Finally, the second end of optical fiber 1 is inserted into third mounting hole 23, limited due to radial, so hair
Optical module 3, lens 4 and optical fiber 1 are successively arranged along the optical axis direction of optical path, are then adjusted to the position of the second end of optical fiber 1
Section, when adjusting, can carry out according to detector, so that coupling efficiency obtains stablizing guarantee, third is fixedly mounted finally by optical cement
In mounting hole 23.
Laser adjusts after the output of light emitting module 3 by the optical path of lens 4, defeated in the second end of optical fiber 1 after over-focusing
Enter, and carries out optical transport using optical fiber 1.
It is additionally provided with location hole 24 in the rear class of third mounting hole 23, there are two the conical surfaces for the setting of location hole 24, can be used for
The equipment of fixed optical fiber, which connects, to be used.
The Die Embodiment of fixator:
The fixator of above scheme is solid for being mounted directly for optical fiber due to being provided with the minimum third mounting hole in aperture
It is fixed, so the fixator of this case needs special mold that could make molding.
Referring to Fig. 5, the mold of fixator includes upper mold insert 51, lower mold insert 52, pin 54 and edge column 53, and upper mold insert 51 is under
Mold insert 52 surrounds die cavity 56 with merging, and pin 54 and edge column 53 are coaxial positioned opposite, and pin 54 and edge column 53 are respectively positioned on mold insert
Between 51 and lower mold insert 52.
Pin 54 along axis is provided with boss 511 and pillar 512 in die cavity 56, and boss 511 is arranged in multi-step,
Shape matches with the first mounting hole, and pillar 512 is arranged on the axial end face of boss 511, the shape of pillar 512 and second
Mounting hole matches, i.e., both ends have straight outer wall, and centre has the conical surface 513, and pillar 512 is provided on axial end face along axis
Location hole 514, pin 54 are provided with support column 542 and convex needle 541 in die cavity 56, and the axial direction of support column 542 is arranged in convex needle 541
On end, the outer wall of support column 542 is provided with the conical surface, and shape and the location hole 24 of support column 542 match, and convex needle 541 is inserted into
To location hole 514.Since the smaller and size with optical fiber of convex 541 size of needle matches, the outer diameter of convex needle 541 is less than pillar
512 outer diameter is used to form small third mounting hole, so being consolidated by end of the location hole 514 to convex needle 541
It is fixed, and injection channel 55 is located on the position of boss 511.
The periphery wall of die cavity 56 and the outer wall of fixator match, the periphery wall, convex of the periphery wall of die cavity 56, boss 511
The periphery wall of the periphery wall of column 512 and convex needle 541 is used for 2 moulding by casting of fixator.
The production method embodiment of fixator:
The production method of the fixator includes:
Convex needle 541 is inserted into location hole 514；
Pin 54 and edge column 53 are arranged between upper mold insert 51 and lower mold insert 52；
Die cavity 56 is poured by injection channel 55；
Fixator 2 is demoulded.
Therefore optical fiber, lens and light emitting module are installed respectively by the mounting hole of coaxial setting, then
It may be implemented in and do not need radially to adjust, especially the cooperation of optical fiber and third mounting hole, since the diameter of optical fiber is smaller, therefore
Cooperated by the third mounting hole of same size with it, can then realize optical fiber limit in the radial direction, limits light using jig
Fine axial position, it is no longer necessary to adjust optical fiber, be fixed finally by optical cement, due to the size phase of mounting hole and optical fiber
It matches therefore fixation can be completed using few optical cement, realize the installation and debugging that facilitate of mode of laser group through the above scheme, and
Performance is more stable.
