Abstract
The utility model discloses an automatic focusing device of a marking machine. The automatic focusing device comprises an optical bench, a galvanometer, a field lens and a red-light focusing device, wherein the field lens is arranged right above the marking surface of a workpiece and connected with the bottom of the galvanometer, the optical bench is mounted on the side of the galvanometer, the red-light focusing device at an inclined state is arranged between the optical bench and the galvanometer. The red light generated by a laser passes through the optical bench and reflected by the galvanometer, and the reflected light ray is vertically emitted through the field lens, and crossed with the inclined light ray from the red-light focusing device and the converges with the inclined light ray on one point, and the cross point is the marking focus, so that the focusing process is simple and convenient. The automatic focusing device has features of compact appearance, simple construction, convenient focusing, and flexible use.
Description
Technical field
The utility model relates to laser marking machine, particularly a kind of marking machine automatic focusing mechanism.
Background technology
Traditional laser marking machine focusing method is at present, laser instrument produces after laser, laser is expanded through extender lens, be mapped to swingable mirror surface and reflex on field lens, form a laser point on mark workpiece, ruddiness is now to be the state overlapping with laser, ruddiness by field lens perpendicular to surface of the work, the position at ruddiness place is mark position, because laser has a distance after focusing on by field lens on mark workpiece, is called focal length.So current this pattern marking machine, can only locate and can not focus, the method of focusing is at present: first a fixing sheet metal is put in to mark surface of the work, by transferring the lifting of light pedestal, look for focus, marking effect preferably time, is focus, and this to focus mode not too convenient, be the defect that mark field exists now, do not obtain fine solution always.
Utility model content
The utility model proposes a kind of marking machine automatic focusing mechanism, solved the problem that laser marking machine in prior art focuses mode inconvenience, this focusing mechanism profile is small and exquisite, simple structure, and focusing is convenient, uses flexibly.
The technical solution of the utility model is achieved in that
Marking machine automatic focusing mechanism, comprise optical bench, galvanometer, field lens and ruddiness focusing mechanism, described field lens be positioned at workpiece mark face directly over, and be connected to the bottom of described galvanometer, the sidepiece of described galvanometer is installed described optical bench, and described ruddiness focusing mechanism is set between described optical bench and described galvanometer.
Described ruddiness focusing mechanism is slant setting, and it is towards to above-mentioned workpiece mark face; In described ruddiness focusing mechanism, be provided with red emission device, can send ruddiness.
Described galvanometer is a kind of high-performance electric rotating machine designing for optical scanner application specially, and motor partly adopts a kind of high-precision position sensor, is mainly used in the fast accurate location to light beam.
Described ruddiness focusing mechanism the inside arranges red emission device, after ruddiness device switches on power, rational position is adjusted to in apparatus system position, and when main optical path ruddiness intersects with it, crosspoint is focus.
The ruddiness that laser instrument produces is through optical bench, and through described vibration mirror reflected, the light of reflection vertically penetrates through described field lens, and the light slanting out with above-mentioned ruddiness focusing mechanism intersects and converges at a bit, and this intersection point place is mark focal length.During mark, only need this intersection point to aim at mark workpiece face, adjusting position just can mark.
The beneficial effects of the utility model are, the marking machine time-consuming and inaccurate problem of focusing of repeatedly focusing before overcoming, and this focusing mechanism focusing is convenient, uses flexibly, be a kind of innovation mode of focus adjustment method.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
In figure, 1, galvanometer, 2, field lens, 3, optical bench, 4, automatic focusing mechanism, 5, workpiece mark face.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 1, a kind of marking machine automatic focusing mechanism, comprises galvanometer 1, field lens 2, optical bench 3 and ruddiness focusing mechanism 4, sends the ruddiness light cross bearing of ruddiness and laser instrument generation by ruddiness focusing mechanism 4 is set.
Galvanometer 1 is a kind of high-performance electric rotating machine designing for optical scanner application specially, and motor partly adopts a kind of high-precision position sensor, is mainly used in the fast accurate location to light beam.
Field lens 2 be positioned at workpiece mark face 5 directly over, and be connected to the bottom of described galvanometer 1, the sidepiece of described galvanometer 1 is installed optical bench 3, and described ruddiness focusing mechanism 4 is set between optical bench 3 and galvanometer 1.
Ruddiness focusing mechanism 4 is slant setting, is provided with red emission device in ruddiness focusing mechanism 4, can send ruddiness, and it is towards facing to workpiece mark face 5, the angled intersection of ruddiness that its light sending and field lens 2 reflect.
Ruddiness focusing mechanism 4 the insides arrange red emission device, after switching on power, rational position are adjusted to in apparatus system position, and when the ruddiness sending when main optical path ruddiness and described red emission device intersects, crosspoint is focus.
The utility model has overcome former marking machine, and to focus mode loaded down with trivial details, and adjusting device is located inaccurate defect, and this automatic focusing mechanism structure is ingenious, and focusing is convenient, use flexibly, and in laser marking machine focusing field, be a kind of pattern of innovation.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
