Detailed description of the invention
Be described further below with reference to accompanying drawing 1 to accompanying drawing 3 pairs of the utility model, but protection domain of the present utility model should do not limited with this.
Contrast accompanying drawing 1 to accompanying drawing 3:
A kind of laser scanning system of the utility model, comprises computer, laser instrument 1, X scanning mirror 2, Y scanning mirror 3, X galvanometer 4 and Y galvanometer 5 and field lens 8, arranges a heat abstractor at the base of X galvanometer 4 and Y galvanometer 5; And engage a shift unit at the base side of X galvanometer 4 and Y galvanometer 5.
Owing to being the same in X galvanometer and the heat abstractor at Y galvanometer place and the structure of shift unit with annexation, therefore following illustrate only with the heat abstractor at X galvanometer 4 place and shift unit for example is described.
Concrete, this heat abstractor comprises an airflow line 61, a part for described airflow line 61 and the base 41 of X galvanometer 4 form an air-flow cavity 10, and this air-flow cavity 10 passes through for compression cold airflow, and the arrival end of described airflow line 61 connects a refrigerator 62.A part for described airflow line 61 arranges a breach 611 mated with the base 41 of described X galvanometer 4, and this breach 611 blocks with base 41 and forms described air-flow cavity 10; This breach 611 is square structure.
Described refrigerator 62 produces cold air, and these cold airs will move in air-flow cavity 10 along airflow line 61, and X galvanometer 4 in use owing to being subject to the irradiation of laser, therefore can produce fuel factor, causes X galvanometer to be heated generation thermal migration; Now, due to the effect of the base 41 of X galvanometer 4, make delivered heat on X galvanometer 4 on this base 41; Now, carrying out heat exchange when moving to the cold air in air-flow cavity 10 by with the heat be transferred on base 41, making the stable decline of base 41, thus cooling effect is produced to X galvanometer 4, decreasing thermal migration.Cold air after heat through passing to base 41 carries out heat exchange will continue to move to along airflow line 61 port of export of this airflow line 61.This technology achieves the cooling of X galvanometer 4 by the mode of heat exchange thus greatly reduces thermal migration.
In order to accelerate the movement of cold air in airflow line 61, the output of described refrigerator 62 connects a compressed air pump 63 for compressing the cold air of described refrigerator output.Completing of heat exchange can be accelerated like this.
In order to ensure to reduce thermal migration as far as possible, also shift unit is set in a side of described base 41.This shift unit 7 comprises a gear 71 and drive motors 72, and this gear 71 is connected with a joggle for driving described X galvanometer 4 to be shifted with base 41 side of described X galvanometer 4.In addition, in order to ensure that described X galvanometer 4 moves stable, arrange a groove 411 at the left surface of the base 41 of described X galvanometer 4, this groove 411 mates a guide rail 20.
The utility model combines the effect of heat abstractor and shift unit, the thermal migration of X galvanometer and Y galvanometer is reduced as far as possible, ensure that precision.Concrete this laser scanning system continuous operation more than 48 hours, the error caused because of laser scanning system is in 0.0001 millimeter.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned embodiment and revise.Therefore, the utility model is not limited to detailed description of the invention disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this description, these terms just for convenience of description, do not form any restriction to the utility model.
