BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat plate (neon) sign apparatus, and more particularly, to a method for manufacturing a device which is a flat plate yarn in which a gas injection tube, especially a protruding encapsulation portion, is completely removed.

In general, a neon sign device may be used as a light emitting device for displaying a character or a picture (hereinafter, referred to as an 'advertising design') used for advertising purposes. The neon sign apparatus is manufactured by heating a glass tube to deform it into a desired shape and then injecting an inert discharge gas such as neon into the glass tube.

The problems with such a conventional neon sign device are that they are relatively bulky, that the overall structure including the frame (means for supporting the glass tube) is large, and that the glass tube is broken and a high pressure of at least 1 [㎸] is applied. Can be pointed out.

On the other hand, in order to deform the glass tube of a certain diameter, as is well known, a portion of the glass tube is heated to transition to a partially molten state, and then the bending portion is bent (bending) to make a predetermined advertising design. Therefore, the advertisement design that can be realized by the conventional neon sign device can not only be limited to the diameter of the glass tube, but also the size of the characters and figures that can be expressed through the glass tube is bent.

In order to solve the problems of the conventional neon sign device is a flat neon sign device. Referring to Figure 1a in more detail, the front plate 10 and the back plate 20, which is displayed in the advertising design is coupled in parallel with a predetermined gap (G), the top and rear plates of the front plate 10 ( 20 is formed on the bottom surface of the back surface 20 of the upper surface cavity (24) of the ITO (Induim Tin Oxide) or ATO (Antimony Tin Oxide) coating film 12, 22, which is a transparent electrode. The fluorescent layer 30 which emits light is formed. The cavity refers to a space where a discharge is made, and the advertisement design is determined by the cavity.

The front plate 10 and the rear plate 20, which are configured and coupled in this way, are sealed by a sealing material 40 disposed between the outer edges thereof, and are made in a vacuum state, and the gap G is formed by the sealing material 40. Is formed. The so-called discharge gas (eg, He, Ne, Xe), which is an inert gas, is injected into the gap G and the cavity 24 formed by the plates 10 and 20. For reference, in addition to the flat neon sign device having the above-described configuration, in particular, a device having a different arrangement of electrodes is disclosed in detail in Korean Patent Publication No. 10-2001-68169.

Meanwhile, in order to inject a discharge gas between the gap G and the cavity 24, as shown in FIG. 1B, an approximately cylindrical injection tube 50 is adhered to the injection hole 26 provided in the rear plate 20. It should be fixed. At this time, a liquid glass similar to the plates 10 and 20 is used as the adhesive fixing material 60, and is preferably used after being melted by a heat bonding means such as a torch. The melting point should be lower.

After discharging the discharge gas through the injection tube 50 prepared as described above, the injection tube 50 must be sealed. Referring to FIG. 1C, the middle portion of the injection tube 50 is connected to the thermal bonding means ( Heated to H) and sealed as shown in FIG. 1D.

After a series of encapsulation processes, the length d (hereinafter, "encapsulation length") of the injection tube 50 maintains the encapsulation portion 50 'protruded about 15 mm to 30 mm. In FIG. 1D, the end surface of the encapsulation part is expressed as a test tube shape that is turned upside down. However, since the lower part of the injection tube 50 is melted and recessed by the heat of the heat joining means, the shape is similar to that illustrated in FIG. 1E. Will be taken.

As described above, the conventional flat neon sign apparatus has an encapsulation protruding by the encapsulation length d, which requires much attention in transporting, storing or handling. It also acts as a constraint during the completion of the product, testing and assembling separate accessories.

Therefore, the technical problem of the present invention is to propose a method for manufacturing a device which is a flat yarn from which the gas injection pipe (protrusion encapsulation) is completely removed.

The technical features of the present invention are basically the peripheral edges of the front plate 110 and the rear plate 120 is sealed to form a predetermined gap (G), the injection hole 124 at a predetermined position of the front plate or the rear plate Applied to a flat plate device for providing a), the first process of placing the cylindrical injection tube 140 on the injection hole 124, sealing the plate portion in contact with the injection tube through the first sealing material 150, and injection After the second sealing material 160 is inserted into the tube, the second process of evacuating the flat plate apparatus and injecting the discharge gas, and heating the plate at a position facing the second sealing material to melt the second sealing material And a third process of sealing a part of the gap adjacent to the injection hole, and a fourth process of melting the first sealing material to remove the injection tube.

According to the present invention, the melting points of the first sealing material 150 and the second sealing material 160 are lower than the melting points of the plates 110 and 120, and the melting points of the second sealing material are lower than the melting points of the first sealing material.

In addition, the material of the first sealing material 150 and the second sealing material 160 according to the present invention, unlike the adhesive fixing material 60 of the glass material shown in Figure 1b is that of EVA (Ethylene Vinyl Acetate) or Polyamide material It features.

The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings. Prior to this, the terms or words used in the present specification and claims are defined in the technical spirit of the present invention on the basis of the principle that the inventor can appropriately define the concept of the term in order to explain his invention in the best way. It should be interpreted to mean meanings and concepts. In addition, when it is determined that the detailed description of the known function and its configuration related to the present invention may unnecessarily obscure the subject matter of the present invention, it should be noted that the detailed description is omitted.

First, referring to FIG. 2, a flat sign apparatus (hereinafter, referred to as a 'flat sign apparatus') in which a gas injection tube is removed according to the present invention basically includes a front plate 110 and a rear plate 120. As described, the gap G is formed through the sealing member 130, but the peripheral edge thereof is sealed. The front plate 110 and the back plate 120 are glass plates, and the back plate 120 is for injecting vacuum exhaust and inert gas into a predetermined position, preferably near the periphery. A circular through hole 124 is provided.

Here, the diameter R of the injection hole 124 will be set to about 3 mm to 5 mm, but the present invention is not limited thereto. In addition, the injection hole 124 may be provided in the front plate 110 instead of the rear plate. If the injection hole is provided in the front plate 110, the technical matters that can be changed accordingly can be easily guessed. Therefore, hereinafter, it is assumed that the injection hole 124 is provided in the rear plate 120 for the convenience of description.

According to an exemplary embodiment of the present invention, similar to the flat plate apparatus described with reference to FIGS. 1A to 1E, an ITO (Induim Tin Oxide) or an ATO may be disposed on the upper surface of the front plate 110 and the lower surface of the rear plate 120. Coating films 112 and 122 which are transparent electrodes of (Antimony Tin Oxide) are formed, and a cavity (not shown) including a fluorescent layer (not shown) is formed on an upper surface of the rear plate 120. Since the essential technical idea of the present invention is a series of manufacturing processes for encapsulating and removing the injection tube 140 to be described later, the present invention is not limited to the structure, arrangement, and shape of the electrode and the cavity.

Therefore, hereinafter will be described in detail with reference to Figure 3a to 3d the manufacturing process of the device is a flat plate in which the injection tube is removed according to the present invention.

3A is a view illustrating an injection tube coupling process (S310), in which a cylindrical injection tube 140 having a predetermined length is positioned on an injection hole 124 of a rear plate, and a portion where the injection tube and the lower plate contact each other is melted. 1 It is bonded (sealed) through the sealing material 150. Here, the first sealing material 150 is a material such as E.V.A (Ethylene Vinyl Acetate) or Polyamide, and as mentioned above, a lower melting point is used than the plates 110 and 120.

As shown in FIG. 3B, after the second sealing material 160 is inserted into the injection tube 140, a separate vacuum evacuation means and a discharge gas supply are not supplied to the upper end 141 of the injection tube 140. In connection with the means, a vacuum exhaust (Out) and a discharge gas injection (In) process is performed (S320).

After the S320 process is performed, as shown in FIG. 3C, the front plate 110 facing the second sealing material 160 is heated through a separate heating means to melt the second sealing material 160 by injecting holes. 124 and a portion of the gap G adjacent to the injection hole is sealed (S330). Here, the second sealing material after being sealed will be in the same state as the member number 160 '. In the present embodiment, the second sealing material may be set to the same material as the first sealing material, but the present invention is not limited thereto.

In this encapsulation process, the melting point of the second sealing material 160 is a melting point of the second sealing material should be lower than the melting point of the first sealing material 150 used for coupling the injection pipe 140 in the S310 process. This is because the first sealing material 150 may be remelted while the second sealing material 160 is heated, and the sealing state thereof may be destroyed.

In addition, in FIG. 3C, the shape of the second sealing member 160 is expressed in the form of a square. However, in the above-described step S320, the shape of the second sealing member 160 may be set to a spherical shape for smoother vacuum exhaust and discharge gas injection.

Next, as shown in FIG. 3D, the sealing portion of the injection tube 140, that is, the first sealing material 150, is melted through a separate heating means to separate and remove the injection tube 140 (S340).

For reference, the region A in the drawing shows the yaw groove A caused by the volume change caused by the second sealing material 160 penetrating into the gap G in the step S330. The occurrence of the recess A can be prevented by appropriately adjusting the volume of the second sealing member 160 inserted in the S320 process. In this way, in addition to the pre-action method for adjusting the volume of the second sealing material in advance, it is also possible to apply a post-action method for filling a separate sealing material in the groove (A) generated.

In the flat yarn manufacturing apparatus of the present invention manufactured by the above-described process (S310 ~ S340) is a state in which the injection tube 140 is completely removed, that is, without a protruding encapsulation 50 '(see Fig. 1d) as in the prior art Becomes Therefore, it is possible to obtain an effect that transportation, storage or handling thereof becomes very easy.

As described above and described with reference to a preferred embodiment for illustrating the technical idea of the present invention, the present invention is not limited to the configuration and operation as shown and described as described above, it is a deviation from the scope of the technical idea It will be understood by those skilled in the art that many modifications and variations can be made to the invention without departing from the scope of the invention. Accordingly, all such suitable changes and modifications and equivalents should be considered to be within the scope of the present invention.
