Summary of the invention
The purpose of this utility model provide a kind of can 180 ° the laser scanning heads of rotation arbitrarily, laser scanning head can be done 0 ° of-180 ° of any directions rotation, make the installation on production line of being easy to of laser marking device, and reducing the requirement of workpiece to be machined to frock, very convenient laser beam is to the mark on workpiece different angles plane.Solved exist in the prior art can only be toward the direction carry out mark facing to target, workpiece to be machined is had relatively high expectations to frock, can not rotate adjusting angle arbitrarily, very inconvenient problem operates.
The technical scheme that the utility model adopted is; a kind of can 180 ° the laser scanning heads of rotation arbitrarily; comprise the front lens that is installed in web joint; with 45 ° of mirrors are installed on the beam expanding lens seat that is connected with web joint successively; rear lens; laser designator and first order catoptron; it is characterized in that; reflecting surface optical axis one end of first order catoptron connects second level reflector apparatus by bearing on the beam expanding lens seat; connect a scanner head at second level reflector apparatus; respectively adorn an X-axis galvanometer and Y-axis galvanometer at scanner head X axis and Y-axis to the position; 45 ° of second level catoptrons of one side are housed before the X-axis galvanometer, field lens and protective glass also are housed successively at reflecting surface one end of Y-axis galvanometer.
The utility model feature is that also described scanner head can second level reflecting surface incident light axis be that 0 ° of-180 ° of rotation is carried out in the axle center.
The beneficial effects of the utility model are, the present laser marking machine on the market of contrast, scanner head of the present utility model 0 ° of-180 ° of rotation flexibly, can satisfy the marking requirement on workpiece different angles plane, no matter be upper and lower surface, side at article or the plane mark that becomes 0 ° of-180 ° of angle in surface level, only need to adjust the angle of scanner head, just can easily satisfy the demand.It has solved existing various laser marking machine scanner head installation direction and has all fixed, can only carry out mark facing to target toward the direction, can not rotate adjusting angle and workpiece to be machined having relatively high expectations arbitrarily to frock, it is very inconvenient to operate, whenever change a kind and will reinstall adjustment once, very influence the problem of work efficiency.
The utility model can 180 ° the laser scanning heads of rotation arbitrarily, project organization is simple, and is practical, is easy to processing and manufacturing, also very conveniently carries out improvement in functionality for original laser marking machine.Research and development to laser marking machine has positive popularizing action.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The utility model can 180 ° the laser scanning heads of rotation arbitrarily; as Fig. 1; shown in Figure 2; comprise the front lens 1 that is installed in web joint 11; with with beam expanding lens seat 12 that web joint 11 is connected on 45 ° of mirrors 2 installing successively; rear lens 3; laser designator 5 and first order catoptron 4; reflecting surface optical axis one end of first order catoptron 4 connects second level reflector apparatus by bearing 16 on beam expanding lens seat 12; connect a scanner head 18 at second level reflector apparatus; scanner head 18X axially and Y-axis respectively adorn an X-axis galvanometer 7 and Y-axis galvanometer 8 to the position; 45 ° of second level catoptrons 6 of one side are housed before the X-axis galvanometer, field lens 9 and protective glass 10 also are housed successively at reflecting surface one end of Y-axis galvanometer 8.
Laser of the present utility model produces twice 90 ° of emissions in the whole optical path system, the reflection of laser is to finish 90 ° reflection by the reflector apparatus of 45 ° of catoptrons 4 of the first order; Laser-bounce is reflected by 45 ° of catoptrons in the second level 6 in second reflection unit, finishes 90 ° reflection through X-axis galvanometer 7 and Y-axis galvanometer 8, by field lens 9 and protective glass 10 Laser emission is arrived the target surface again.Laser scanning head 18 is fixed on the reflection unit of the second level, and scanner head 18 can carry out 0 °-180 ° rotations arbitrarily from the top down and the bottom up with second level reflection unit; First order catoptron 4 uses trim ring 14 and shape of the mouth as one speaks circle 13 to be contained on the beam expanding lens seat 12, and second level reflection unit has adopted bearing to be connected with beam expanding lens seat 12; Second level reflection unit utilizes the bearing arrangement rotation, and bearing 16 uses clamp ring ring 15 to compress the 45 ° of reflection units in the second level, and connects by web joint 17, will use certain dynamics during rotation sweep head 18, and stronger stability is arranged after being rotated in place, and can not move.Laser designator 5 indication ruddiness also successively through 45 ° of mirrors, first and second grade reflector apparatus reflexes on the target surface, adjusts the mark precision of rotation sweep head 18 by the very convenient assistance of visible indication ruddiness luminous point.
Scanner head 18 of the present utility model can incident light axis be that 0 ° of-180 ° of rotation is carried out in the axle center.Make no matter to be to become the plane of 0 ° of-180 ° of angle to carry out mark, all become a reality, its only needs to adjust the angle of scanner head 18, just can easily satisfy the various needs of mark in article target upper and lower surface, side or in surface level.Fix thereby solved existing various laser marking machine scanner head installation direction, can only carry out mark facing to target toward the direction, can not rotate adjusting angle arbitrarily, the problem of inconvenient operation; Also solve workpiece to be machined to the having relatively high expectations of frock, whenever changed a kind and will reinstall adjustment once, very influenced the problem of work efficiency.
The utility model can 180 ° the laser scanning heads of rotation arbitrarily, project organization is simple, and is practical, is easy to processing and manufacturing, also very conveniently carries out improvement in functionality for original laser marking machine.Research and development to laser marking machine has positive popularizing action.
