OBJETO DE LA INVENCIÓN La presente invención se refiere al rayado de la superficie de un conductor óptico plano, como por ejemplo el metacrilato, que permite la refracción de la luz que por él circula.OBJECT OF THE INVENTION The present invention relates to the scratching of the surface of a flat optical conductor, such as methacrylate, which allows the refraction of the light circulating through it.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Actualmente en el mercado existen dos sistemas que permiten la refracción de la luz que circula por un conductor óptico. El primero de estos sistemas es el fabricado y distribuido por la multinacionales PLEXI y ATAOS, empresas que tienen patentes en las que se reivindica una lámina de metacrilato transparente de 8mm., en cuyo interior se encuentran suspendidas nanopartículas que reflejan la luz que circula a través de la lámina.There are currently two systems on the market that allow the refraction of the light that circulates through an optical conductor. The first of these systems is the one manufactured and distributed by the multinationals PLEXI and ATAOS, companies that have patents in which an 8mm transparent methacrylate sheet is claimed, inside which nanoparticles that reflect the light circulating through are suspended. of the sheet.
El segundo sistema fabricado y distribuido por la empresa PRIXMEX. Este sistema consiste en una serigrafía de pequeños puntos blancos sobre la superficie del metacrilato y con una densidad variable, dependiendo de la distancia al punto de luz y el grosor del material. El primer sistema descrito tiene el inconveniente con respecto a la invención que nos ocupa de que el rendimiento luminoso es inferior, así como el coste del mismo, el cual es considerablemente superior al descrito en esta patente.The second system manufactured and distributed by the PRIXMEX company. This system consists of a silkscreen of small white dots on the surface of the methacrylate and with a variable density, depending on the distance to the point of light and the thickness of the material. The first system described has the drawback with respect to the invention that concerns us that the light output is lower, as well as the cost thereof, which is considerably higher than that described in this patent.
El segundo sistema si bien tiene un rendimiento luminoso similar al que tratamos en esta patente, tiene el inconveniente, igual que en el primer caso, de su elevado coste, al cual además hay que añadirle las limitaciones de su tamaño.The second system, although it has a luminous efficiency similar to the one discussed in this patent, has the disadvantage, as in the first case, of its high cost, to which the limitations of its size must also be added.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
La invención que nos ocupa se basa en rayar la superficie del conductor, para permitir la refracción de la luz que por él circula. El rayado de la superficie debe ser finísimo, para garantizar una correcta refracción.The invention at hand is based on scratching the surface of the conductor, to allow the refraction of the light that circulates through it. The scratching of the surface must be very fine, to ensure proper refraction.
Si nosotros tomamos una plancha de metacrilato y le aplicamos una luz por el costado, observamos como por el otro extremo sale una luz que tiene casi la misma intensidad de la que hemos aplicado, esto quiere decir que la luz es capaz de circular por el interior del metacrilato.If we take a methacrylate iron and apply a light on the side, we see how at the other end a light comes out that has almost the same intensity as we have applied, this means that the light is able to circulate inside of methacrylate.
Si a esta plancha le hacemos varias rayas con un objeto punzante, veremos que dichas rayas se encienden cuando son iluminadas. Esto es debido a que estamos alterando la superficie del conductor óptico, ya que dicha plancha debería estar pulida.If we make several stripes on this plate with a sharp object, we will see that these stripes light up when they are illuminated. This is because we are altering the surface of the optical conductor, since said plate should be polished.
Si por el contrario en dicha plancha de metacrilato pintamos pequeños puntos blancos, observamos que también se encienden esto es debido a que hemos desalojado el aire que existe entre los puntos y el metacrilato, por lo que esta zona deja de ser conductora. El metacrilato es un conductor óptico con respecto al aire, al no existir aire deja de ser conductor.If, on the other hand, in said methacrylate plate we paint small white dots, we observe that they also turn on this is because we have dislodged the air that exists between the points and the methacrylate, so this area is no longer conductive. Methacrylate is an optical conductor with respect to air, since there is no air, it stops being conductive.
Hemos observado que cuando se altera la superficie del metacrilato mediante rayado, observamos que si el rayado lo hemos hecho uniforme sobre toda la superficie la luz que se refleja será mucho más intensa a medida que nos acercamos al punto de luz. Esto nos indica que para poder conseguir un reparto uniforme de luz sobran rayas de luz.We have observed that when the surface of the methacrylate is altered by scratching, we observe that if the scratching has made it uniform over the entire surface, the light that is reflected will be much more intense as we approach the point of light. This indicates that in order to achieve a uniform distribution of light there are plenty of light streaks.
Esto nos lleva a la necesidad de hacer un rayado de densidad variable para así obtener un reparto uniforme de la luz. Dicho rayado debe aumentar de densidad a medida que nos alejamos de la fuente de la luz. El objeto de nuestra invención es el hacer un rayado de densidad variable que permite la refracción de la luz uniformemente y para distintos anchos de metacrilato. Para llevar a cabo este rayado dispondremos de una cinta transportadora de superficie antideslizante de unos 8 o lOm. de largo por 1,5 o 2m de ancho. Sobre dicha cinta colocaremos el metacrilato que vamos a tratar.This leads us to the need to make a scratch of variable density in order to obtain a uniform distribution of the light. Such scratching should increase in density as we move away from the source of the light. The object of our invention is to make a scratch of variable density that allows the refraction of light evenly and for different widths of methacrylate. To carry out this scratch we will have a non-slip surface conveyor belt of about 8 o lOm. long by 1.5 or 2m wide. On this tape we will place the methacrylate that we are going to treat.
Por encima de la cinta transportadora situaremos unos triángulos que pueden ser equiláteros o isósceles, que estarán fijos y que presionan sobre la cinta, sobre el metacrilato, mediante tres pistones neumáticos. Estos pistones sirven para graduar la presión de los triángulos sobre el metacrilato.Above the conveyor belt we will place triangles that can be equilateral or isosceles, which will be fixed and that press on the belt, on the methacrylate, by means of three pneumatic pistons. These pistons serve to adjust the pressure of the triangles on the methacrylate.
Entre los triángulos y la placa de metacrilato pondremos un abrasivo de tipo flexible en dos o tres capas, en nuestro caso utilizaremos como abrasivo el "ESCOTCH BRITE". Por detrás de cada triángulo situaremos un descargador de energía estática, de los existentes en el mercado. Este proceso origina mucha energía estática, lo que impide la consecución de resultados óptimos en el proceso de rayado, con los descargadores conseguimos superar este problema.Between the triangles and the methacrylate plate we will put an abrasive of flexible type in two or three layers, in our case we will use the "ESCOTCH BRITE" as an abrasive. Behind each triangle we will place a static energy arrester, of those existing in the market. This process causes a lot of static energy, which prevents the achievement of optimal results in the scratching process, with the arresters we manage to overcome this problem.
El número de triángulos aconsejable para poner en la cadena sin fin y para conseguir que en una sola pasada se obtenga un rayado óptimo, es de cinco. Con este número conseguimos que los defectos de distribución del abrasivo en cada triángulo quede compensado con los otros.The number of triangles advisable to put in the endless chain and to achieve that in a single pass an optimal scratch is obtained, is five. With this number we get the abrasive distribution defects in each triangle to be compensated with the others.
El tamaño de los triángulos dependerá del tamaño del metacrilato que vamos a tratar. Los triángulos equiláteros tendrán desde el mismo ancho que el metacrilato hasta 80cm. más, y para el caso de los triángulos isósceles estas medidas serían las de la base del mismo.The size of the triangles will depend on the size of the methacrylate that we are going to treat. The equilateral triangles will have from the same width as methacrylate up to 80cm. more, and in the case of the isosceles triangles these measures would be those of the base of the same.
Una vez que hemos fijado el material abrasivo a los triángulos, y que mediante los pistones hemos dado la presión deseada, la cual oscilará entre 0,5 y 2 kilos dependiendo de la superficie del triángulo, deslizaremos el metacrilato debajo de ellas mediante una cinta transportadora.Once we have fixed the abrasive material to the triangles, and that through the pistons we have given the desired pressure, which will oscillate between 0.5 and 2 kilos depending on the surface of the triangle, we will slide the methacrylate under them by means of a conveyor belt .
Detrás de cada triángulo pondremos un descargador de energía estática. Este conjunto estará bajo los efectos de un humidificador para garantizar una humedad óptima durante todo el proceso, la cual se debe mantener en un mínimo de un 40% de humedad relativa. Según este sistema seremos capaces de tratar entre 10 y 20m. lineales por minuto. BREVE DESCRIPCIÓN DE LOS DIBUJOSBehind each triangle we will put a static energy arrester. This set will be under the effects of a humidifier to ensure optimum humidity throughout the process, which must be maintained at a minimum of 40% relative humidity. According to this system we will be able to treat between 10 and 20m. linear per minute. BRIEF DESCRIPTION OF THE DRAWINGS
