Description
Technical field
The utility model relates to laser aid, a kind of specifically novel routing laser module.
Background technology
Routing laser module is a kind of hi-Fix utility appliance that is applied on the plant equipment; See also Fig. 1; Routing laser module in the known technology mainly is made up of housing 101, laser module, Lens assembly three parts, and this laser module comprises LD102 (semiconductor laser), driving PCB A103, power lead 104; Lens assembly comprises collimation lens (three-chip type or a slice aspheric surface formula), line eyeglass 105 and eyeglass seat 106.The laser point that laser module penetrates projects line eyeglass 105 through collimation lens, with this laser point is refracted as the laser bright line of an angle of divergence greater than 120 degree, and launches outside housing 101.
In the prior art; Laser module and collimation lens are arranged in the housing 101 and fix through the mode of can epoxy resin, and simultaneously, line eyeglass 105 is fixed on the relevant position of housing 101 ends; In actual use; For the laser rays that makes ejaculation reaches the accuracy requirement of design, four screws 107 that generally can be provided with through adjustment housing 101 ends change the adjusting play 108 of housing 101; Thereby change the relative position of line eyeglass 105 and laser point, adjust the ejaculation angle of laser bright line with this.The weak point of this kind structure is after being the adjusting play variation of housing 101; Deformation can take place in housing 101; Its stress can't be eliminated after the deformation, and the stress of passing housing 101 in time can slowly discharge, and line eyeglass 105 also can change with the position of laser point thereupon; Cause the precise decreasing of laser module, it is suitable constant to bring for client's use.
The utility model content
To the deficiency and the defective of above prior art, the purpose of the utility model is to provide a kind of novel routing mode of laser.
The purpose of the utility model realizes through adopting following technical scheme:
A kind of novel routing laser module comprises housing, laser module, Lens assembly, is provided with a flexible rubber ring between the eyeglass seat of said Lens assembly and the tolerance clearance of housing, and this flexible rubber ring is arranged on the eyeglass seat, and the medial surface of its outer shroud and housing is tangent; Said housing is provided with adjusting screw, and this adjusting screw laterally is arranged in the housing with respect to the axis of housing, and the one of which end contacts with the lateral surface of Lens assembly.
As the optimal technical scheme of the utility model, offer groove on the said eyeglass seat, said flexible rubber ring is arranged in this groove.
As the optimal technical scheme of the utility model, said adjusting screw is provided with two, and it is with the both sides of being located at this housing of the axis symmetry of housing.
Compared with prior art, the utility model is simple in structure, and when regulating the precision of laser module, housing does not have deformation to produce, and the mode of laser group leader time uses, and its stable accuracy can not change.
Description of drawings
Fig. 1 is the structural representation of the routing laser module in the known technology.
Fig. 2 is the structural representation of the novel routing laser of the utility model module.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further:
See also Fig. 2, be the structural representation of the novel routing laser of the utility model module.
This routing laser module comprises housing 201, laser module, Lens assembly.This laser module comprises LD202 (semiconductor laser), driving PCB A203, power lead 204; This Lens assembly comprises collimation lens (three-chip type or a slice aspheric surface formula), line eyeglass 205 and eyeglass seat 206, and this collimation lens (figure do not show) is located in the eyeglass seat 206, and it is corresponding with collimation lens that this line eyeglass 205 is located at the relevant position of housing 201 ends.
Said laser module and eyeglass seat 206 are located in the housing 201, between the tolerance clearance of eyeglass seat 206 and housing 201, are provided with a flexible rubber ring 207, and this flexible rubber ring 207 is arranged on the eyeglass seat 206, and the medial surface of its outer shroud and housing 201 is tangent.Comparatively preferably scheme does, on this eyeglass seat 206, offers a groove 208, and this flexible rubber ring 207 is arranged in this groove 208, is subjected to displacement to prevent this flexible rubber ring 207.
Said housing 201 is provided with two adjusting screw 209; This two adjusting screw 209 is with the both sides of being located at this housing 201 of axis 210 symmetries of housing 201; This adjusting screw 209 laterally is arranged in the housing 201 with respect to the axis 210 of housing 201, and the one of which end contacts with the lateral surface of Lens assembly.
When regulating the precision of laser module, can the position of eyeglass seat 206 in housing 201 be changed through rotation adjusting screw 209, and change the relative position of line eyeglass 205 and laser point, adjust the ejaculation angle of laser bright line with this.
The preferred embodiment that the above is merely the utility model is not the practical range that is used for limiting the utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by the scope of the utility model claims.
