Abstract
The utility model relates to a tilting mirror type laser marking machine which comprises a laser light source and a conduction mechanism used for transferring laser beams onto a target according to pictures and characters. The tilting mirror type laser marking machine is characterized in that a reflecting mirror which receives laser beams from one direction is driven by a step motor via a speed reducer, and a reflecting mirror which receives reflecting light from another direction is driven by the other set of step motors via the speed reducer, and the reflecting mirror can transfer the laser beams onto the target via a focusing mirror corresponding to the reflecting mirror. The machine has the characteristic of high scanning resolution.
Description
The utility model relates to a kind of rotary mirror type laser marking machine.
Existing rotary mirror type laser marking machine comprises LASER Light Source and by picture and text laser beam is transferred to conduction mechanism on the target.Realize this function, mainly, also claim galvanometer, depict picture and text thereby i.e. speculum line focus mirror scans laser beam on target by a rotation mirror motor that has speculum.During work, add certain current/voltage for the galvanometer stator, rotor just has an angle position corresponding to current/voltage, variation by stator current voltage can make rotor produce corresponding angular, so the rotor revolution moves an angular displacement alpha, angular displacement alpha of the also corresponding rotation of speculum, in other words, the angle of minimum resolution degree of the galvanometer rotor angle of minimum resolution degree of speculum just.At present, because technology and components and parts will make the angle of minimum resolution degree reach very meticulous still very difficult.
For this reason, the purpose of this utility model is to overcome the deficiency of above-mentioned prior art and a kind of rotary mirror type laser marking machine is provided, and it can adopt existing components and parts to obtain sufficiently high angular resolution.
The technical scheme that realizes the utility model purpose is: a kind of rotary mirror type laser marking machine, comprise LASER Light Source and laser beam is transferred to conduction mechanism on the target by picture and text, it is characterized in that: stepper motor is connected with input shaft of speed reducer by shaft coupling, its output shaft is connected with the speculum of accepting laser beam from a direction, another stepper motor then is connected with another input shaft of speed reducer by shaft coupling, its output shaft with accept aforementioned catoptrical another speculum from other direction and be connected.
And the ratio coverage of decelerator can be 1: 25～1: 200.
By the technical program, angular displacement alpha of the every generation of stepper motor, if the speed reducing ratio of decelerator is f, then the respective corners displacement of speculum generation is α/f, that is the angle of minimum resolution degree of speculum is the 1/f of stepper motor, and this programme can diminish speculum angle of minimum resolution degree by the speed reducing ratio f that increases decelerator, utilize homemade stepper motor and the decelerator easily buied on the market, just can obtain sufficiently high angular resolution.Test shows that this machine all has significant effect aspect scanning resolution, reliability and the economy.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is the stereogram of the technical program.
Fig. 2 is the schematic diagram of one group of transmission scheme.
With reference to Fig. 1, Fig. 2, this mark machine comprises LASER Light Source 4 and by picture and text laser beam is transferred to conduction mechanism on the target 5.Concrete scheme is, accept the speculum 3 of laser beam from a direction, drive by decelerator 2 by stepper motor 1, accept aforementioned reverberation and reflex to the focus lamp 6 that is being provided with on the other direction and laser beam is projected on the target 5 through decelerator 8 driven mirror 9 through this focus lamp 6 by another group stepper motor 7.
Further formation can be, stepper motor 1 is connected with the power shaft 12 of mechanical type decelerator 2 by shaft coupling 11, and its output shaft 13 is connected with speculum 3.
And stepper motor 1 also can directly be connected with decelerator 2, and perhaps, the motor shaft 10 of stepper motor 1 is exactly the power shaft 12 of decelerator 2 simultaneously.The speed reducing ratio of decelerator 2 can be selected in the scope at 1: 25～1: 200 according to desired angular resolution.
