Description

A method and a system for color marking of metals
The present invention relates to a method and a system for color marking of metals. The present invention is used among others for marking metals in the advertising industry, the home appliance industry, the consumer electronics industry, the automotive industry, the jewellery industry and the art.
Color laser marking of the metals consists in the formation of thin layers (several tens of nm) of transparent or partially transparent oxides on the metal surface. A white light illuminating the surface of the sample is reflected from both the surface of the oxide and the boundary surface of the oxide and metal area. A suitable thickness of the oxide causes - through the interference of the two reflected beams - the formation of the color effect, wherein the color type follows directly from the refractive index of the layer and its thickness. An international patent application No. WO2010034891A1 describes a method involving the formation of color marking in two stages. Firstly, a thick layer of oxide (red) is prepared on the surface of the material, and then in a second stage the obtained layer is thinned so as to obtain a specific color. The authors of that invention claim that obtaining a specific, repeatable color in a straight way, i.e. directly in one step, is impossible. U.S. patent US5703709 describes a method that uses two systems of optical scanners and liquid crystal mask. The application does not indicate the need to control the distance to the marked material, but it presents the possibility of co-operation of the system with an automatic feeder. U.S. patent US6613161 describes a method for color marking consisting in formation of transparent or partly transparent oxides with a specified thickness on the metal surface by suitably chosen laser wavelength and pulse energy. The invention is focused on the use of a catalyst such as e.g. oxygen to shorten the time of marking, and indicates the possibility of marking a number of different metals and the use of different lasers (mostly UV - excimer leasers and solid state lasers with harmonic lasers) . The invention does not disclose the factors that directly affect the formation of a specific color, and repeatability of the process. U.S. patent application No. US2004194235A1 describes a method for color marking of the metals through the use of additional chemicals, such as polymerizable inks containing additionally other substances serving as catalysts. Thus, there is still a need to provide a process for color marking of metals that gives reproducible results both when these are placed at the incorrect distance from the lens of the system and in the case when the following elements piece to piece will be different concerning the dimensions (normally the dimension differences of 0.5 mm - do not allow to obtain the same color) . Moreover, there is sought a method that allows the marking become independent from the state of burn-in of the laser, aging processes (a degradation of the laser power), or the track of the beam becoming dirty, or degradation / contamination of the external mirrors (of the scanner) . Surprisingly, these problems are solved by the present invention .
The first object of the invention is a system for color marking of metals by laser comprising a laser for generating a laser beam, which is directed by an electronically controlled element correcting a divergence of the beam, followed by galvo mirrors of the scanner changing the angle of the beam or shifting the beam in a plotter system and then through the optics onto the marked surface area at a predetermined distance from the optics, which is characterized in that it comprises a control unit for reading a signal proportional to the power read by a head of a power meter, into which preferably a part of the laser beam is directed from an uncoupling mirror, which is positioned in the path of the laser beam between the galvo mirrors of the scanner and the surface, preferably in front of or behind the optics, and for reading the signal proportional to the distance from the distance sensor, and for sending the signals controlling a deflection of the beam in the galvo mirrors of the scanner and its divergence, and for sending the laser power control signal, wherein the unit is controlled by means of a control device, preferably a computer. Another object of the present invention is a method for color marking of the metals by laser comprising a generation of the laser beam that is directed through the electronically controlled element correcting the divergence of the beam, and through the element changing the angle of the beam or shifting the beam, preferably in the galvo or the plotter system, onto the marked surface by the optics, characterized in that it comprises
a) reading the distance of the optics from the marking surface b) reading the power of the laser beam or the pulse energy, preferably in front of or behind the optics
c) correcting by means of the control unit of the laser power, of the beam divergence and deflection or its displacement on the basis of reading values obtained in the step a) and b) . Equally preferably, the method according to the present invention is characterized in that in the step a) the reading of the distance of the optics from the surface is performed using the distance sensor. More preferably, the method according to the present invention is characterized in that in the step b) the reading of the laser beam power is performed using the head of the power meter or the pulse energy, which the beam from the uncoupling mirror is directed into, preferably the mirror positioned between the elements changing the angle or the position of the beam, and the optics. In a further preferred embodiment of the present invention, the method is characterized in that the control unit is controlled by the control computer. Most preferably, the method according to the present invention is characterized in that the element changing the angle of the beam or shifting the beam is the galvo scanner or the plotter with the mirrors .
The present invention allows to obtain the reproducible results on the marked objects both when they are placed at the incorrect distance from the lens system, and when the next elements piece to piece are different concerning the dimensions (normally the dimension differences of 0.5 mm - do not allow to obtain the same color) . The present invention allows the effect become independent from the state of burn-in of the laser (in the normal systems over a period of a few to several minutes, the power at the output of the system changes in a small degree), the aging processes (the laser power degradation due to aging of its components), or becoming dirty (becoming dusty) of the path of the beam guide, or the degradation / contamination of the external mirrors (of the scanner or the plotter) . By measuring the distance to the marked material, the output power of the system and the information of the location of the laser beam within the field of work (at given moment), which is used in the present invention, the system automatically adjusts the power (the energies) of the laser beam and its initial divergence so that to obtain at the material surface the fixed value of the laser radiation power density. The present invention allows for a simple modification of previously existing systems for marking of metals with functions of the color marking. The only requirement is to use: a sensor controlling the level of the power or energy at the output of the system, a non-contact proximity sensor with an accuracy of 0.1 mm or better (such as laser triangulation sensors from Lauze DS_ODSL8_V66_C66_500 series), an electronically controlled beam expander (e.g. varioSCAN from SCANLAB company) . The presented method and kit of the present invention further does not increase the cost of operation of the system. It may be even lower, because there is no need for precise adjusting of the position (height) of the object relative to the optics (lens) of the system in the case of a short series that has the advantage of reducing the time it takes to prepare the station for marking the next (new) element, even if the marking is to be monochromatic. Exemplary embodiments of the invention are shown in the drawing, in which: Figure 1 and 2 illustrate the systems according to the present invention.
Example 1
The system for color marking of the metals comprises the laser L, the output beam W of which passes through the electronically controlled by the signal 4 the optical system V that is used to change the divergence of the laser beam W, which then falls on the first mirror of the scanner X system changing the angle of this beam or shifting this beam in the X axis, and then falls onto the second mirror of the scanner Y changing the angle of this beam or shifting this beam in the Y axis, and then falls on the uncoupling mirror M, which directs the beam by two paths to the output optics F of the system and the head of the power meter P. The beam after passing the output optics F falls on the marking surface S, the distance of which in relation to the optics F is measured by the non-contact DS sensor. Simultaneously, the control unit U receives the signals 1 sent from the distance sensor and 2 from the power meter, on the basis of which, as well as on the basis of the signals 3 and 5 controlling the X and Y mirrors, the control unit U generates the signal controlling the divergence of the beam 4 and the signal controlling the power 6 of the laser L. The operation of the system according to the present invention consists in that the control unit U generates the signal 4 controlling the V that corrects the divergence of the beam W in such a way that, irrespective of the current distance of the marked surface S in relation to the output optics F, the position of the beam focus W is exactly on the marked surface S. At the same time, the control unit U generates the signal controlling the power 6 of the laser L in such a manner that the power value measured by the measuring heads P is consistent with expectations. At the same time, on the basis of control signals 3 controlling the mirror X and the signal 5 controlling the mirror Y, the coordinates of the spot in the working area is determined and the control unit U generates the signal 4, which corrects the beam divergence W that allows for maintaining a constant power density across the whole area of the marked field S.
Example 2
The system as in Example 1 wherein, alternatively, on the basis of the value of the signals 3 controlling the mirror X and the signal 5 controlling the mirror Y, the coordinate of the spot in the working area is determined and the control unit U generates the signal 4, which correcting the value of the power control signal 6 of the laser L allows to maintain a constant power density across the whole area of the marked field S.
Example 3
The system as in Example 1, except that the head of the power meter P carries out the measurements without using the uncoupling mirror M in the path of the laser between the galvo mirror of the scanner Y and the surface S. The system is shown in the Figure 2.
