Abstract

Surface scratching system of a flat optical conductor consisting of the use of a self-sliding conveyor (4), through which the methacrylate sheet (3) to be treated slides. On it five supports (5) are placed that each hold a triangle, isosceles or equilateral (1). On each triangle (1) there are three pneumatic pistons (2) that regulate their pressure, which will range between 0.5 and 2 kilos depending on the surface of the triangles. Under the triangles an abrasive material (ESCOTH BRITE) will be placed and behind it we will have static arresters (6). Through a humidifier we will maintain the humidity at least 40 percent.

Description

Scratch system of the surface of a flat optical conductor

Technical Field of the Invention

The present invention relates to the scratching of the surface of a flat optical conductor, such as the methacrylate, which allows the refraction of light by it circulates

State of the art

There are currently several systems on the market that allow the refraction of the light that circulates through a conductor optical.

One of these systems conceives in a sheet of 8mm transparent methacrylate, inside which are suspended nanoparticles that reflect the light flowing through of the sheet.

Another system consists of a silkscreen of small white dots on the surface of 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 performance Luminous is lower, as well as the cost thereof, which is considerably higher than described in this patent.

The second system although it has a performance luminous similar to the one we treat in this patent, it has the inconvenient, as in the first case, of its high cost, at which also has to add the limitations of its size.

Brief Description of the Invention

The invention at hand is based on scratching the conductor surface, to allow the refraction of the light that It circulates through it. The scratch of the surface must be very fine, to guarantee correct refraction.

If we take a methacrylate iron and we apply a light on the record, we will observe as on the other extreme comes a light that has almost the same intensity as we have applied, this means that the light is able to circulate inside the methacrylate.

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.

If on the contrary in said plate methacrylate we paint small white dots, we will observe that they also turn on this is because we have evicted the air that exists between the points and methacrylate, so that area Stop being a driver. Methacrylate is an optical conductor with with respect to air, since there is no air, methacrylate ceases to be driver.

We have observed that when the methacrylate surface by scratching, we will see that if the striped we have made it uniform over the entire surface the light that is reflected will be much more intense as we approach the lightpoint. This tells us that in order to get a cast Light uniform light streaks.

This leads us to the need to make a scratch of variable density to obtain a uniform distribution of light. Said scratch should increase in density as we move away from The source of the light.

The object of our invention is to make a variable density scratch that allows light refraction evenly and for different widths of methacrylate. To carry After this scratch we will have a conveyor belt non-slip surface of about 8 or 10 m. long by 1.5 or 2 m. Wide. On this tape we will place the methacrylate that we are going to try.

Above the conveyor belt we will place some triangles that can be equilateral or isosceles, which will be fixed and pressed on the tape, on the methacrylate, by three pneumatic pistons. These pistons serve to adjust the pressure of the triangles on the methacrylate.

Between the triangles and the methacrylate plate we will put a flexible and fiberglass abrasive in two or three hats.

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 achievement of optimal results in the scratching process, with the downloaders we overcome this problem.

The number of triangles advisable to put in the endless chain and to get that in a single pass you get An optimal scratch is five. With this number we get the abrasive distribution defects in each triangle remain compensated with the others.

The size of the triangles will depend on the size of the methacrylate we are going to deal with. Equilateral triangles they 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 basis of it.

Once we have set the abrasive material to the triangles, and that through the pistons we have given the pressure desired, which will range 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.

Behind each triangle we will put a downloader of static energy. This set will be under the influence of a humidifier to ensure optimum humidity humidity during the whole process, which must be kept at a minimum of 40% of RH. According to this system we will be able to deal with 10 and 20 m. linear per minute.

Brief description of the drawings

The patent presents a single drawing that corresponds to a part of the conveyor belt plant, in which is the triangles (1) that can be isosceles or equilaterals On these triangles we put three pistons tires (2) that regulate the pressure of the triangles (1) in whose lower part is located the abrasive material, on the methacrylate (3) that we are going to treat. The methacrylate (3) slides on the conveyor belt (4), and has supports (5) that hold triangles (1) and static arresters (6).
