Technical field
The present invention relates to a kind of linear laser module (Laser Module for Projecting a LinearLaser Beam), particularly a kind ofly adjust the angle that laser beam enters cylindrical lens, to improve linear linear laser module.
Background technology
Because laser beam has the transmission direction unanimity, and the illumination characteristic that can not descend rapidly, thereby be widely used on engineering construction measurement level or the vertical level meter because transmission range increases.In various level meter; use the laser module that can on object, project the linear laser light beam through regular meeting; with as measurement level or vertical laser light beam source; therefore; whether laser module can accurately project the linear laser light beam of straight line on object, just become the key factor of level meter measurement accuracy.
Fig. 1 is No. 202050 disclosed " adjustable laser module device " 100 of the novel patent of TaiWan, China, it is the rear end 112 that laser generator is installed on hollow body 110, cylindrical lens 120 is locked in front end 111 grooves 116 of hollow body 110 with screw 121,122 and elasticity anti-dazzling screen 123, and respectively offering a dark groove 113,114 that reaches hollow body 110 centers near hollow body 110 both sides of cylindrical lens 120, and only keep each tiny junction surface 115 up and down.During adjustment, then, respectively screw 121 or 122 is screwed,, make it produce deflection, and then adjust the angle that laser beam that laser generator produced enters cylindrical lens 120 with compressing hollow body 110 front ends 111 according to the demand of required adjustment direction.
Adjust the angle that laser beam enters cylindrical lens 120 though this kind mode can be reached, make adjustable laser module 100 can project the purpose of the linear laser light beam of straight line.Yet, because the junction surface 115 of hollow body 110, after adjustment remaining stress relief, can cause the precision of the linear laser light beam that adjustable laser module 100 throwed to change, the measurement accuracy that causes level meter is deviation to some extent also.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of linear laser module, it does not have the phenomenon of residual mechanical stress after adjustment, can keep the degree of accuracy of the linear laser light beam that is throwed.
For reaching above-mentioned and other purpose, the invention provides a kind of linear laser module, comprising: main body base, laser beam generator, collimation lens, cylindrical lens seat and cylindrical lens.Main body base has first end, second end and is communicated with first end and the saturating through hole of second end, and the laser beam generator is arranged near in the saturating through hole of second end, in order to produce a laser beam.Collimation lens is arranged in the saturating through hole between first end and second end, after laser beam datum is a parallel beam, again through the refraction of cylindrical lens, and projects required linear laser light beam.Wherein, cylindrical lens is to be installed on the cylindrical lens seat, the cylindrical lens seat then is connected in first end of main body base rotationally, so that with saturating through hole radially is turning axle, carry out the angular setting of parallel beam incident cylindrical lens, reach the linear purpose of the linear laser light beam that improvement projects.

Embodiment
Please refer to the stereographic map and the exploded view thereof of a kind of linear laser module 200 of the preferred embodiment of the present invention shown in Fig. 2 and Fig. 3 difference.This linear laser module 200 comprises: main body base 210, for example the laser diodes light beam generator 220, for example are the collimation lens 230 of convex lens, collimation lens seat 240, cylindrical lens seat 250, cylindrical lens 260 and elasticity anti-dazzling screen 270.
Wherein, main body base 210 is the column structure of a hollow, and it has the saturating through hole 213 that is communicated with first end 211 and second end 212.In order to produce the laser beam generator 220 of laser beam, can be placed in by second end 212 of main body base 210 in its saturating through hole 213.After 230 of collimation lenses were positioned over collimation lens seat 240 earlier, first end 211 by main body base 210 was placed in its saturating through hole 213 again, so that the laser beam that laser beam generator 220 is produced, collimation is a parallel beam.
In order to project the linear laser light beam on an object, the parallel beam behind the collimation must be by being arranged at the cylindrical lens 260 on the cylindrical lens seat 250, so that parallel beam can be via the refraction of cylindrical lens 260, and projects the linear laser light beam.Wherein, when parallel beam during with respect to the incident angle out of plumb of cylindrical lens 260 axial 261, will reflect and produce crooked linear laser light beam, and, then can reflect the linear laser light beam of generation straight line when parallel beam when being vertical with respect to the incident angle of cylindrical lens 260 axial 261.Therefore, project the rectilinearity of linear laser light beam in order to improve, cylindrical lens seat 250 must be able to carry out axial 261 adjustment of device cylindrical lens 260 thereon, make parallel beam with respect to axial 261 incident angle of cylindrical lens 260 for vertical.
In Fig. 3, the periphery of first end 211 of main body base 210 respectively is provided with a screw hole 215 up and down, cylindrical lens seat 250 then is respectively arranged with two teats 251,252 with respect to two screws 215, and pass the perforation 253,254 of two teats 251,252 respectively, and screw in two screws 215 with screw 216,217.That is to say, cylindrical lens seat 250 radially is a turning axle 219 with the saturating through hole 213 of main body base 210, be connected in first end 211 of main body base 210 rotationally, so that carry out axial 261 adjustment of device cylindrical lens 260 thereon, make parallel beam with respect to axial 261 incident angle of cylindrical lens 260 for vertical.
In Fig. 3, the fixed form of cylindrical lens 260 is the perforation 273,274 of passing elasticity anti-dazzling screen 270 with screw 271,272 respectively, screws in regular turn in the screw 214,218 of the screw 255,256 of cylindrical lens seat 250 and main body base 210 again.Wherein, screw 255,256,214 and 218 is arranged at the both sides of turning axle 219, and therefore, cylindrical lens seat 250 can be by the compressing of screw 271,272, to carry out the angular setting of parallel beam incident cylindrical lens, to improve the rectilinearity of the linear laser light beam that is projected.In addition, 281,282 on screw screws in the screw 257,258 of cylindrical lens seat 250 respectively, and is resisted against on the cylindrical lens 260, is installed on levelness on the cylindrical lens seat 250 to carry out cylindrical lens 260.
Though the present invention is open by preferred embodiment, the disclosed embodiments are not to be used for limiting the present invention.Various changes and retouching that any those of skill in the art of this area are done without departing from the spirit and scope of the present invention all should belong to protection scope of the present invention.Therefore, protection scope of the present invention is with being as the criterion that appending claims was defined.
