Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Please refer to Fig. 1 to Fig. 3, be a preferred embodiment of the present utility model, this collimation head unit comprises collimation microscope base 1, the collimation eyeglass 3 that is positioned at the fiber connector 2 of described collimation microscope base 1 one ends and is positioned at described collimation microscope base 1 other end, described collimation eyeglass 3 is slidingly connected with described collimation microscope base 1 by fixedly sleeved mirror cover 4 in its outer peripheral edges, and described collimation head unit comprises that also one can drive the governor motion 5 of described mirror cover 4 advance and retreat.Like this, because described collimation eyeglass 3 is slidingly connected with described collimation microscope base 1 by fixedly sleeved mirror cover 4 in its outer peripheral edges, described collimation head unit comprises that also one can drive the governor motion 5 of described mirror cover 4 advance and retreat, can realize collimating the advance and retreat of eyeglass 3 by regulating described governor motion 5, thereby realize adjustment, and then realize out of focus described laser focusing point position 10 (please refer to Fig. 4 A to Fig. 4 C) height and position.Have very strong operability, and simple in structure, and effect is clear and definite, and is with low cost.
Below above-mentioned each ingredient is described in detail respectively.
Described collimation microscope base 1 is cylindric, and its inside is provided with the cavity 11 that passes through for laser beam 9.Fiber connector 2 is by the end of some screw retention in described collimation microscope base 1.The other end of described collimation microscope base 1 (being an end of corresponding described collimation eyeglass 3) is along described collimation eyeglass 3 flange arrangement 12 that extends radially outwardly out.Flange arrangement 12 can be in order to be fixed in whole collimation head unit one side of focusing lens (not shown).Described collimation microscope base 1 also is provided with a breach 13 near a side of flange arrangement 12, uses for governor motion 5 to be connected with described mirror cover 4.Described collimation microscope base 1 inwall is provided with a first step structure 14, the second step structure 41 of overlapping 4 outer walls in order to the described mirror that coincide.First, second ledge structure 14,41 cooperates the moving range that can limit collimation eyeglass 3.
The orienting lug 52 that described governor motion 5 comprises a differential head 51 of fixedlying connected with described collimation microscope base 1, driven by described differential head 51, described orienting lug 52 pass described breach 13 and overlap 4 with described mirror and fixedly connected.Differential head 51 is fixing by the differential head bracket 53 that is fixed on described collimation microscope base 1 outer wall, and like this, when the needs adjustment collimates the position of eyeglass 3, but turn differential head 51 makes it drive orienting lug 52 and then drives mirror cover 4 slip in collimation microscope base 1.In the present embodiment, differential head 51 adopts Direct Action Types, and it can be eliminated because of the backhaul gap of adopting general spiral differential head to cause, and mobile accuracy and speed that can more effective control collimation eyeglass 3 realize the control of collimation eyeglass 3 positions more accurately
In order to realize collimating the location of eyeglass 3, the position that described mirror overlaps the corresponding described collimation eyeglass 3 of 4 inwalls is provided with the 3rd ledge structure 42 of locating for described collimation eyeglass 3.Described mirror overlaps 4 outer ends and is provided with inwall by the trim ring 6 that is threaded, and also is folded with a spacer ring 7 between described trim ring 6 and the described collimation eyeglass 3.
After the position of finishing collimation eyeglass 3 is adjusted, need overlap 4 to mirror and lock, therefore, present embodiment also comprises the locking mechanism 8 that is located on described collimation microscope base 1 outer wall.Position at described collimation microscope base 1 corresponding described mirror cover 4 is provided with a screw, and locking mechanism 8 is that a spiral shell is located at the screw nut assembly in the described screw.The described screw nut assembly of turn is replaced on the lateral wall of described mirror cover 4 front end of described screw rod, can realize the positioning and locking to mirror cover 4.
Fig. 4 A to Fig. 4 C shows the optical schematic diagram that utilizes present embodiment to regulate laser focusing point position:
Fig. 4 A figure is illustrated in the most normal focal position, laser beam 9 with certain dispersion angle incides on the collimation eyeglass 3 from fiber end face, by regulating differential head 51, to collimate eyeglass 3 and be adjusted to the centre position, fiber end face is on the interior focus of collimation eyeglass 3, and making the light beam behind the collimation is directional light, again by focusing on, make laser focusing in normal focal position, the hot spot minimum of welding this moment;
Fig. 4 B and Fig. 4 C are the situations when regulating differential head 51 back collimation eyeglass 3 positions that form in the entopic left and right sides, by regulating differential head 51, form positive and negative out of focus.Because fiber end face is not on the focal position, so collimation back laser beam has certain contraction, but fail to form directional light, to such an extent as to the focal position after focusing on is in the both sides of normal focus.Positive and negative out of focus all will increase the diameter of hot spot, but different out of focus will reach different welding effects.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
