Description
Technical field
The present invention relates to a kind of optical module and adjusting gear thereof, particularly relates to the adjusting gear of a kind of laser luminescence component and laser luminescence component.
Background technology
As shown in Figures 1 and 2, be respectively in the past laser luminescence component 10 and the adjusting gear 20 of laser luminescence component 10.
This laser luminescence component 10 comprises a lens barrel 11, and is arranged at lens 12, in this lens barrel 11 and is arranged at focusing tubes 13, in this lens barrel 11 and is arranged at laser light-emitting component 14 in this focusing tube 13, and one resists and encircles 15.
This lens barrel 11 comprises one around an axis Z and define one first perforation, 112 first barrel 111.This first perforation 112 has a lens construction section 113, and one in contrast to this lens construction section 113 and inner peripheral surface have threaded collar around the canned paragraph 114 that is spirally connected.
These lens 12 are to be arranged at this lens construction section 113.
This focusing tube 13 comprises second barrel 131 that centers on this axis Z and define one second perforation 132, this second perforation 132 has the small-bore section 133 of contiguous this lens construction section 113, an and large aperture section 134 in contrast to this small-bore section 133, this second barrel 131 also has a shoulder face 135 that supports that is formed between this large and small aperture section 134,133, the outer peripheral face of this second barrel 131 have threaded collar around, this focusing tube 13 is to be fixed in this canned paragraph 114 that is spirally connected by the screw lock mode.
This laser luminescence component 14 be arranged in this large aperture section 134 and one illuminating part 141 towards this small-bore section 133, it is that screw lock is in this large aperture section 134 and this laser light-emitting component 14 is resisted against should be to shoulder face 135 around, this resistance ring 15 that the inner peripheral surface of this large aperture section 134 has threaded collar.
The adjusting gear 20 of this laser luminescence component 10 is that collocation one laser light receiver 210 uses, this adjusting gear 20 comprises a base 21, and is arranged on height control group 22 on this base 21 along a vertical direction Y, and a holder 23 that is arranged at these height control group 22 tops.This lens barrel 11 is to be fixed in this holder 23 corresponding to this laser light receiver 210.
This height control group 22 comprises that a pilum 221, is hubbed at the adjustment ring 222 of this pilum 221, and a telescopic mast 223 that driven by this adjustment ring 222, and this holder 23 is to be arranged at this telescopic mast 223 tops.
Focus when adjusting, the operator rotates this focusing tube 13 by the hand-screw mode to adjust relative distance with these lens 12, and observe the reception situation of this laser light receiver 210 simultaneously, whereby judging whether this laser light-emitting component 14 has been displaced to this lens 12 focal point F places, and make the output of laser light can reach distortionless result of use.
Yet; when reality is adjusted because this lens barrel 11 is to produce displacement and focusing work by helicitic texture with focusing tube 13, so during fabrication, in the focusing also regular meeting be subject to helicitic texture; and cause having the low problem of precision to take place with light shaft offset, such as:
1. this lens barrel 11 will carry out screw thread processing during fabrication with focusing tube 13, so can be comparatively complicated on making, and because pitch (pitch) size of screw thread can influence the feeding degree of this focusing tube 13, so under mass-produced prerequisite, make the less accurate screw thread of pitch and tend to make cost, time to improve many.
2. in addition because this focusing tube 13 is to come displacement in this lens barrel 11 by helicitic texture, so the optical axis of this laser light-emitting component 14 can be subjected to the precision of screw thread and skew and the generation of departing from is arranged, and,, the more feasible optical axis that has departed from is difficult for judging that the shortcoming of position takes place in whole adjustment process so having because this laser light-emitting component 14 is to rotate to advance.
Summary of the invention
Therefore, purpose of the present invention is do not need via screw thread processing, the laser luminescence component of the operation of also focusing to be to provide a kind of.
And another object of the present invention is to be to provide a kind of energy adjusting gear that auxiliary this laser luminescence component is accurately focused.
So laser luminescence component of the present invention comprises a lens barrel, and is arranged at lens, in this lens barrel and is arranged at focusing tube in this lens barrel, and one is arranged at the interior laser light-emitting component of this focusing tube.
This lens barrel comprises that one centers on an axis and defines one first first barrel of boring a hole, and a some glue passage that runs through this first barrel and be connected with this first perforation.
This focusing tube is to be sheathed on this first perforation along this axis direction, and by being fixed in this lens barrel at this glue passage mid point glue.
The adjusting gear of laser luminescence component of the present invention comprises adjusting mechanism, that holder, that a base, is arranged at this base along a vertical direction is arranged at this base and is arranged at sliding seat between this holder and the adjusting mechanism and at least one flexible member that is arranged between this holder and the sliding seat.
This holder comprises one for first mounting hole of fixing this lens barrel and being provided with along a horizontal direction.
