Laser marking processing is to utilize the high-energy of laser to act on surface of the work, makes surface of the work reach the moment gasification, and presses projected path, inscribes out literal, pattern with certain depth.Be widely used in industries such as electronic devices and components, integrated circuit (IC), electrical engineering and electric apparatus, mobile communication, hardware, tool fitting, accurate apparatus, glasses clock and watch, jewellery ornaments, auto parts machinery, plastic press key, building materials, pvc pipe material, medicine equipment.
In the laser marking process, can accurately be worked into the position of appointment in order to make literal or pattern, will need to adopt the mode of location.The locate mode of traditional laser marking processing is to adopt visible light (like ruddiness) to simulate the neighboring profile of processing content always, and makes its surface that projects work piece, regulates the position of work piece in view of the above, thereby reaches the purpose of location.
This kind localization method is fairly simple, but also exists simultaneously the location not accurate enough, and operating effect is fraud point intuitively inadequately.
The utility model content
The utility model technical problem to be solved provides the laser marking device of a kind of camera location, adopts this equipment to carry out laser marking, and the location is simple, convenient, accurate.
The technical scheme that the utility model solves the problems of the technologies described above is following: the laser marking device of a kind of camera location; Comprise laser instrument, beam expanding lens, first laser mirror, second laser mirror, laser marking head and the workpiece processing platform of launching laser; Said laser instrument, said beam expanding lens, said first laser mirror set gradually along laser optical path; Said first laser mirror laterally arranges with second laser mirror that is used to receive and reflect the first laser mirror reflect beams of laser light, and the said second laser mirror laser light reflected light beam projects said workpiece processing platform through said laser marking head; Said first laser reflective mirror and said second laser mirror are all-trans to laser, to the visible light full impregnated, at said laser marking head input, adopt and are provided with ccd video camera with the coaxial access way of said second laser mirror.
Said laser instrument emission laser beam arrives the first laser reflective mirror through beam expanding lens; Reflect through the first laser reflective mirror; The emission light beam reflects through second laser mirror; Reverberation gets into the laser marking head, second laser mirror and camera lens on same axis, promptly be exactly the laser beam that gets into the laser marking head with the entering video camera in visible light on same straight line.
The beneficial effect of the utility model is: at said laser marking head input; Adopt and have access to ccd video camera with the coaxial mode of said second laser mirror; Workpiece can directly be projected in the video camera through optical system in the labelling head, realizes location fast and accurately.
Further, the laser marking device of said camera location also comprises the computer system that is used to receive and show the ccd video camera image, and said computer system links to each other with ccd video camera.
Further beneficial effect: utilize this CCD digital camera head that the scene in the laser marking head sweep limits is imported in the computer system of equipment; When the workpiece that is marked is positioned on the mark platform; Simultaneously on computer screen, also can clearly observe this workpiece; Through the direct content of the required processing of editor in the scene scope, and can adjust the position of processing content, it can be displayed at the position of required processing on workpiece image accurately; Can realize not only accurately but also the location purpose of intuitive and convenient, reach the effect of " What You See Is What You Get ".
Further; Said first laser mirror and second laser mirror are that 45 ° of laser are all-trans, 45 ° of full impregnated eyeglasses of visible light; Said eyeglass all reflects laser; Said incidence angle and angle of reflection are 45 °, promptly are exactly that visible light can pass through first laser mirror and second laser mirror smoothly but visible light is not all reflected; Said eyeglass the one side that receives laser have can the total-reflection laser wavelength coatings.
Further beneficial effect: the one side that receives laser have can the total-reflection laser wavelength coatings can total-reflection laser change the light path of laser; And reflect visible light not, the visible light in the laser that has so just guaranteed to get into labelling head and the camera reception labelling head is on same straight line and coaxial with second laser mirror.
