Utility model content
The main purpose of this utility model is: provide a kind of image information that can vertically obtain workpiece, to improve the workpiece positioning system of the laser marking machine of positioning precision.
For achieving the above object, this utility model provides the workpiece positioning system of a kind of laser marking machine, the workpiece positioning system of this laser marking machine includes: photographic head, reflecting optics, and the image calculating obtained according to described photographic head processes the data handling system of the co-ordinate position information obtaining workpiece；Wherein, described reflecting optics is located at laser marking machine and goes out the position directly below of shaven head, the most described work platforms of described reflecting optics is obliquely installed, and its reflective surface is towards described work platforms, photographic head is towards the reflective surface of described reflecting optics, and the light penetrated from described photographic head arrives the angle of incidence of described reflecting optics and described reflecting optics relative to the angle sum between work platforms equal to 90 degree；The image signal output end of described photographic head is connected with the picture signal input of described data handling system.
Preferably, the angle between described reflecting optics and described work platforms is 45 degree.
Preferably, the workpiece positioning system of laser marking machine also includes that the mobile device for making described work platforms move, described mobile device are located at the bottom position of described work platforms.
The workpiece positioning system of the laser marking machine that this utility model provides, this alignment system is by going out to arrange immediately below shaven head reflex reflector lens at laser marking machine, and it is equal to 90 degree with reflecting optics relative to the angle sum between work platforms from the angle of incidence of the light arrival reflecting optics of photographic head injection, thus ensure that the image that photographic head gets is to obtain from the position directly above of workpiece, overcome in prior art owing to oblique side obtains the inaccurate defect in location caused.

Detailed description of the invention
Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
This utility model provides the workpiece positioning system of a kind of laser marking machine.
The workpiece positioning system of a kind of laser marking machine that the present embodiment provides.The workpiece positioning system of this laser marking machine includes: photographic head 1, reflecting optics 2 and data handling system (not shown).
Reflecting optics 2 is located at the position directly below shaven head 3 of laser marking machine.Owing to the wavelength of laser is about 1064nm.Therefore, laser can penetrate reflecting optics 2 and reach on work platforms 4.It is to say, reflecting optics 2 can't interfere the light path of laser.Reflecting optics 2 is obliquely installed relative to work platforms 4, and its reflective surface is towards work platforms 4.The reflective surface of photographic head 1 orienting reflex eyeglass 2.For ensureing that photographic head can obtain image from the position directly above of workpiece, in the present embodiment, arrive the angle α sum between the angle of incidence γ work platforms 4 relative with reflecting optics 2 of reflecting optics 2 equal to 90 degree from the light of photographic head 1 injection.Those skilled in the art are when knowing, the angle of incidence of light is equal to angle of reflection.In this example, it is assumed that photographic head 1 end is to reflecting optics 2 throw light.Light angle of incidence γ on reflecting optics 2 is equal to reflection angle beta, and reflection light is refracted on work platforms 4.According to the angle sum of a triangle principle equal to 180 degree, for making reflection light vertical with work platforms 4, arrive the angle α sum between the reflection angle beta work platforms 4 relative with reflecting optics 2 of reflecting optics 2 equal to 90 degree from the light of photographic head 1 injection.Owing to angle of incidence γ is equal to reflection angle beta, therefore, the angle α sum between the angle of incidence γ work platforms 4 relative with reflecting optics 2 of reflecting optics 2 is arrived equal to 90 degree from the light of photographic head 1 injection, ensure that reflection light is vertical with work platforms 4, thus ensure that photographic head 1 can obtain image from the surface of workpiece.The image signal output end of photographic head 1 is connected with the picture signal input of data handling system.The image information got is exported to data handling system by photographic head 1.Data handling system then processes according to image information calculating and draws the co-ordinate position information that workpiece is concrete.
Further, for ease of installing, it is preferable that penetrating the angle between eyeglass and work platforms 4 is 45 degree.
Further, obtaining the scope of work platforms 4 image for expanding photographic head 1, in the present embodiment, the workpiece positioning system of laser marking machine also includes the mobile device 5 for making work platforms 4 move, and mobile device 5 is located at the bottom position of work platforms 4.Specifically, mobile device 5 includes X-axis mobile unit and Y-axis mobile unit.Work platforms 4 can be moved in two dimensions by above-mentioned two mobile unit so that workpiece can be positioned at the position directly below of reflecting optics 2.
The workpiece positioning system of the laser marking machine that this utility model provides, this alignment system is by arranging reflex reflector lens in going out of laser marking machine immediately below shaven head 3, and arrive the angle α sum between the angle of incidence γ work platforms 4 relative with reflecting optics 2 of reflecting optics 2 equal to 90 degree from the light of photographic head 1 injection, thus ensure that the image that photographic head 1 gets is to obtain from the position directly above of workpiece, overcome in prior art owing to oblique side obtains the inaccurate defect in location caused.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in scope of patent protection of the present utility model.
