Abstract
The utility model is an auxiliary focusing device of a laser marking machine, which comprises two supports and two light pens that can send out visible parallel beams, and the light pens are connected with a controllable power supply. The two supports can be arranged on a focusing mirror base seat positioned at both sides of a focusing mirror and can move left and right, and the two light pens are rotationally disposed on the two supports respectively. A rotating and translational locking device is arranged on the supports. The left-right translation of the supports and the rotation of the light pens can adjust points of fall of light beams of the light pens on the work table surface. After installing the auxiliary focusing device, the device is adjusted firstly and then the distance between the focusing mirror and the work table is adjusted, then the laser beams are focused on the machined surface of the workpiece on the work table, and the strongest ignescent point is the focus of the focusing mirror, namely, the central point in the scanning area. The light pens are turned on and adjusted for making the points of fall of the two light beams on the machined surface of the workpiece overlap with the ignescent point, then the light pens are locked closely. Hereafter, adjusting the distance between the work table and the focusing mirror when in use can make the superposed light spot of the two light pens be the intersection point of the optical axis and the focal plane of the focusing mirror, thereby facilitating both the focusing and workpiece contraposition.
Description
(1) technical field
The utility model relates to a kind of auxiliary focusing control device and using method, is specially a kind of laser marking machine auxiliary focusing device and using method.
(2) background technology
Laser marking machine is a kind of equipment that carries out marking processing with laser beam, mainly comprises laser generator, scanning system, focus lamp and other relevant control module.Laser beam via scanning system after the incident focus lamp, the light beam of parallel incident is focused on the focal plane of focus lamp, the scanning light beam after the focusing etches the pattern of expectation at surface of the work.When surface of the work is positioned at when focusing on the field lens focal plane, the spot diameter minimum, laser energy density is the highest, etching effect is the meticulousst, most effective.Thereby, when using laser marking machine, always need to regulate the relative distance on focus lamp and work piece surface, surface to be machined is positioned on the focus lamp focal plane.
Focusing in the past is the below that workpiece is placed on focus lamp, control module control laser generator discharges laser beam and acts on the workpiece surface to be machined, operating personnel adjust the relative distance of focus lamp and workpiece surface to be machined, the laser beam that detects by an unaided eye simultaneously acts on the size that surface to be machined forms spark, illustrates that when the spark maximum, when sound is the loudest the workpiece surface to be machined is positioned at the focal plane.The method of this focusing of judgement by rule of thumb bothers for the operating personnel that lack experience very much, reaches optimum state because of being difficult to focusing, thereby influences the marking effect.Simultaneously, the focusing process will be lost a workpiece at least, and will be very unfortunate.People at the thin metallic plate protection workpiece of surface of the work pad last layer, focus according to the situation that light beam acts on the metallic plate, but this moment, sample plane were not the surface of the work of final processing yet, and this mode requires operating personnel to possess higher skill and experience.
In addition, even certain workpiece focusing is finished, invisible because of laser beam, operating personnel are still difficult after changing workpiece places workpiece suitable position and realizes focusing, is not easy to the workpiece contraposition.
(3) utility model content
The purpose of this utility model is a kind of laser marking machine auxiliary focusing device of design, can indicate the position of focal plane and sweep center point, makes focusing and workpiece contraposition process convenient, accurate.
The laser marking machine auxiliary focusing device of the utility model design, laser marking machine contains laser generator, is installed in the focus lamp of focus lamp base, workbench, but focus lamp base or workbench upper and lower translation change the distance between the two; Also comprise two supports, two light pens that can send visible collimated light beam, light pen is connected with controllable electric power.But be installed in to two support move left and right on the focus lamp base of the both sides that are positioned at focus lamp, two light pens are installed in rotation on respectively on two supports.The locking device that rotation and translation are arranged on the support.
There is screwed hole the focus lamp both sides under the focus lamp base, both sides screwed hole and focus lamp center are in line, and a top of the trellis has mounting hole or guide groove, and the translation lock screw is passed the screwed hole under mounting hole or the guide groove connection base, but support move left and right, translation lock screw fixed support and focus lamp base.Rotating shaft or spherical axle joint are arranged on the support, and light pen bar afterbody is installed on rotating shaft or the spherical axle joint, but the spin locking screw of fixed rotating shaft or spherical axle joint and support is arranged on the support.Light pen can rotate along rotating shaft or spherical joint, and the spin locking screw is light pen and support fixedly.
Light pen rotates the angle that promptly changes light pen light beam and focus lamp axis, and translation of the support left and right sides and light pen rotate the drop point of light beam on work top of adjustable lay the grain pen.
After being installed, regulates earlier in this laser marking machine auxiliary focusing device, open laser marking machine and make the primary optical axis of laser beam through focus lamp, accurately adjust focus lamp base or workbench, promptly adjust distance between focus lamp and the workbench by the professional, focus on workpiece machined surface on the work top vertical according to the loudest laser beam that makes of spark maximum, sound with the focus lamp optical axis, be that the workpiece machined surface is its focal plane, this moment laser beam to drop on the strongest " the spark point " that form on the focal plane be the focus of focus lamp, also be the central point of scanning area.Connect the light pen power supply this moment, light pen sends visible collimated light beam, the both sides light pen is adjusted in translation focus lamp two side stands and/or rotation respectively, make drop point and " the spark point " it on of visible light beam on the workpiece machined surface of two light pens overlapping successively, regulate the locking device on the back tightening light pen support, the intersection point of two light pen light beams is exactly the central point of the focus and the scanning area of focus lamp.
When using this laser marking machine focusing mechanism after adjusting is finished, after being placed on workpiece on the workbench, open the power supply of this auxiliary focusing device light pen earlier, regulate the distance of workbench and focus lamp, the light beam of two light pens is intersected on the workpiece machined surface, the workpiece machined surface is exactly the focal plane, and the luminous point of the two light pen light beams that coincide of this moment is the optical axis of focus lamp and the intersection point of focal plane, and focusing and workpiece contraposition are all very convenient.
The beneficial effect of the utility model laser marking machine auxiliary focusing device is: (1) convenient, fast with two light pen light beams, find the laser focus point exactly on the workpiece work surface; Guarantee that workpiece is on the focal plane, makes the marking best results; (2) focus by the light pen light beam, need not to be workpiece of focusing waste; (3) after the Installation and Debugging of this device, help the operating personnel of marking machine to focus and the contraposition of workpiece machining center point, operating personnel's experience and skill required reduction by the visible point of light of light pen; (4) this apparatus structure is simple, is easy to be equipped with on laser marking machine, need not to change the laser marking machine original structure.
