Description

Automatic Etching Glass Control System {Emergency Exit Indication Lamp using Control System of Automatic Slimming Glass}

The present invention relates to an automatic etched glass control system, after forming a pattern and letters through high-pressure spraying using abrasives (water + cerium oxide) on ordinary glass to perform etching and washing at the same time, heating with high heat in a strengthening furnace It relates to an automatic etching glass control system characterized by applying a functional paint to the tempered glass, which is quenched through air to enhance durability and heat resistance.

Conventional safety induction lamps have a problem in that they are made of plastics such as acrylic, which are easily burned, and are lost at high temperatures, making identification difficult.

Existing products have problems in that the patterns and characters are flat and the identification power is poor. Therefore, the technology for processing the patterns and characters in three dimensions is required.

As a widely used glass processing method, a process using a diamond wheel, a laser processing process, a sandblast processing process, and the like are used.

Currently used glass processing methods include diamond wheel processing, laser processing, and sandblasting. The processing process using the diamond wheel is a very difficult method of turning the wheel to the detailed openings of the speaker microphone camera required in the glass substrate for the touch screen by rotating the diamond wheel to cut the glass.

In the processing process using the laser, the cutting surface can form a smooth and precise opening, but there is a problem in that the glass cutting surface is discolored due to a heat treatment phenomenon on the cutting surface, and thus a processing process for removing the discoloration part is separately required.

The sandblasting process is a processing method that polishes or cuts the surface of a material by spraying abrasives from a nozzle. In the past, sandblasting was used as a grinding material, but it was named sandblasting. Currently, aluminum oxide, silicon carbide, or ceramic powder is used. It is used as a grinding material. However, the conventional sandblasting process has a problem in that a separate washing process must be performed after processing.

On the other hand, conventional safety induction lamps are made of plastic, such as acrylic, which is easily burned, and there is a problem that it is difficult to discriminate because it is lost at high temperatures.

In addition, the existing product has a problem in that it is difficult to discern when a fire occurs because the pattern and letters are flat and the identification power is low and the existing guide lamp has low illumination.

These conventional processing processes require a polishing process in which abrasives are embedded in the glass and are cleaned separately.

However, there was a problem that the manufacturing process was complicated and expensive.

In addition, the conventional Patent Publication No. 10-2009-0070792 is a glass substrate etch device that stores the etch system and the etchant and a pressure tank that receives etchant from the storage tank and a etchant by a pump, and supplies etchant to the glass. Consists of etching devices that etch the substrate, the fluid flow regulator that distributes and outputs the pipes and the etchant evenly with automatic valves that supply etchant to the pressure of the pressure tank through the etch device, and the etch area to etch the glass substrate. There was a problem in that the process was complicated and time-consuming, such as a buffer area where an air curtain was installed to recover the etchant on the glass substrate, and an air curtain to remove and dry the etchant remaining on the glass substrate.

In addition, the PCB frame 11 is equipped with a PCB (not shown) in the PCB substrate mounting portion therein, and one side has a coupling protrusion inserted into the "c" groove of the cover frame and the other side supports the lower surface of the cover frame. An LED module (not shown) is mounted by forming an L'-type support portion and forming a groove portion horizontally on both sides of the lower plate binding portion.

In addition, the PCB frame 11 is formed by female threads on both sides of the lower end of the square and screwed with the upper threaded holes of the left and right frames 15, 15'.

The cover frame 13 is attached to the PCB frame 11 by sliding, and at the upper part, two upward slopes face each other with a certain distance around the center so that the ceiling bracket can be coupled to the guide groove inclined upward with a constant width. Addition is formed.

In addition, the cover frame 13 forms an'c'-shaped groove part outward so that the coupling protrusion of the PCB frame 11 is inserted at one end, and is supported by the'L' type support part of the PCB frame 11 at the other end. The'L'-shaped protrusions are formed.

A female screw is formed in the central portion of the'L'-shaped protrusion and is screwed through a screw hole formed in the central portion of the PCB frame 11.

The left and right frames 15 and 15' form a radial vent on the top to naturally convect the heat generated by the LED, thereby reducing heat inside, and forming screw threads with the PCB frame by forming upper threaded holes on both sides. , Forming a lower threaded hole in the lower portion is screwed and fixed with the lower frame (17).

In addition, the left and right frames 15 and 15' are formed with'C'-shaped grooves therein, and are fixed by inserting both sides of the PCB frame 11, tempered glass, and lower frame 17 on both sides of the emergency exit guide lamp.

The controller divides the depth of etching into large, medium, and small, and when the depth of etching is increased, the glass abrasive that can etch the surface of the glass is 75 to 78% by weight of water and 22 to 25% by weight of cerium oxide. The spray angle is 44~45 degrees, and in the middle, it is 79~82% by weight of water as a glass abrasive, and 18~21% by weight of cerium oxide, and the spray angle is 42~43 degrees. The abrasive is 83~85% by weight of water and 15~17% by weight of cerium oxide.
