3 is a process chart showing a process of manufacturing a sign cover from a neon sign type sign according to an embodiment of the present invention,

4 is a process chart showing a process of manufacturing a sign base from a neon sign type sign according to an embodiment of the present invention.

As shown in FIGS. 3 and 4, the neon sign-type signboard manufacturing method is a first step of forming a sign cover 10 made of a synthetic resin material or an acrylic material.

For example, after preparing the cover plate 15 in the form of a plate made of acrylic material, which is the raw material of the sign cover 10, the cover plate 15 in the form of a plate is processed through acrylic CNC processing based on a preset program. After forming the signboard cover 10 made of acrylic material in the form of a whole bar that forms the shape of a letter or symbol, the signboard cover 10 is separated from the cover original plate 15.

The signboard cover 10 formed in this way has a semicircular cross-section and has a shape of a whole bar forming the shape of a letter or symbol.

Here, a method of setting a program for acrylic CNC processing when forming a sign cover is not particularly limited and may be adopted as long as it is a method commonly known in the art.

In particular, when the signboard cover 10 is formed, a cutter 18 having a blade 17 having a symmetrical 1/4 circular cross section may be used, and the cutter 18 at this time is a character formed by the signboard cover 10 B. By cutting the cover plate 15 using the blade 17 while progressing along the trajectory of the symbol shape, the signboard cover 10 in the form of a whole bar that has a semicircular cross section and forms the shape of a letter or symbol Can be molded.

For example, when moving the cutter 18 having the blade 17 of 1/4 circular cross section along the trajectory of a letter or symbol formed by the sign cover 10, one blade of a 1/4 circular cross section ( With 17), the cutter 18 is processed while processing the semicircular cross section by 1/4 circular cross section, and the cutter 18 proceeding in this way completely circulates the trajectory of the character or symbol shape formed by the sign cover 10 Thus, it is possible to form an intact semicircular cross section.

That is, the cutter 18 proceeds from the starting point of the trajectory of a character or symbol formed by the sign cover 10 to process a quarter circular cross section, and after passing through the trajectory return point, the cutter 18 is 1/ 4 The process proceeds while processing the remaining 1/4 circular cross-section opposite to the side where the circular cross-section is processed, and when the cutter 18 returns to the trajectory arrival point (the trajectory start point) in this processing and processing method, the signboard cover 10 ) Intact semicircular cross section can be molded.

Next, as a second step, a step of molding the sign base 13 made of a synthetic resin material or an acrylic material is performed.

For example, after preparing the base plate 16 in the form of a plate made of acrylic material, which is the raw material of the signboard base 13, the base plate 16 in the form of a plate is processed through acrylic CNC processing based on a preset program. After forming the signboard base 13 made of acrylic material in the form of a whole bar forming the shape of a letter or symbol, the signboard base 13 is separated from the base plate 16.

In addition, the groove portion 12 is also formed in the inner region of one side of the signboard base 13.

The signboard base 13 formed in this way has a rectangular cross-section and has a shape of a whole bar that forms a shape of a letter or symbol corresponding to the shape of the signboard cover 10.

Here, a method of setting a program for acrylic CNC machining during signboard base molding is not particularly limited and may be adopted as long as it is a method commonly known in the art.

In addition, a known cutter (not shown) may be used when the signboard base 13 is formed, and the blades in the cutter (not shown) while advancing the cutter at this time along the trajectory of the character or symbol shape formed by the signboard base 13 By cutting the base plate 16 by using (city), it is possible to form the signboard base 13 in the form of a whole bar that has a groove 12 and a square cross section and forms a shape of a letter or symbol.

At this time, when forming the sign base 13, the signboard base 13 can be formed in such a way that the cutter proceeds to completely circulate the trajectory of the letter or sign shape formed by the signboard base 13, and the signboard base 13 can be formed. When cutting the outer shape of the signboard base 13 constituting the back, the groove may also be processed at the same time, or may be processed sequentially through a sequential process.

Separate.

In addition, the groove 12 is also formed in the inner region of one side of the signboard base 13 through acrylic CNC processing based on a preset program.

The signboard base 13 formed in this way has a semicircular cross section and is formed in the form of a whole bar that forms the shape of a letter or symbol.

Even when forming such a signboard base, a method of setting a program for acrylic CNC processing or the like is not particularly limited and may be adopted as long as it is a method commonly known in the art.

In particular, when the signboard base 13 is formed, a cutter 18 having a blade 17 having a symmetrical 1/4 circular cross section can be used, and the cutter 18 at this time is a letter formed by the signboard cover 10 B. By cutting the base plate 16 using the blade 17 while proceeding along the trajectory of the symbol shape, the signboard base 13 in the form of a whole bar that has a semicircular cross section and forms the shape of a letter or symbol Can be molded.

For example, when moving the cutter 18 having the blade 17 of 1/4 circular cross section along the trajectory of the character or symbol formed by the sign base 13, one of the blades of 1/4 circular cross section ( With 17), the cutter 18 is processed while processing the semicircular cross section by 1/4 circular cross section, and the cutter 18 thus proceeding completely circulates the trajectory of the character or symbol shape formed by the sign base 13 Thus, it is possible to form an intact semicircular cross section.

That is, the cutter 18 proceeds from the starting point of the trajectory of a character or symbol formed by the sign base 13 to process a quarter circular cross section, and after passing through the trajectory return point, the cutter 18 is 1/ 4 The process proceeds while processing the remaining 1/4 circular cross-section opposite to the side where the circular cross-section is processed, and when the cutter 18 returns to the trajectory arrival point (the trajectory start point) in this processing and processing method, the signboard base 13 ) Intact semicircular cross section can be molded.

Next, as a third step, a step of mounting the LED module 11 inside the groove 12 of the sign base 13 is performed.

That is, after attaching and fixing the LED module 11 with an adhesive or the like in the groove 12 of the sign base 13, a wire (not shown) extending from the LED module 11 is processed on the sign base 13 It is drawn out through a wire hole (not shown) and wired to the external power supply side.

Next, as a fourth step, a step of completing the neon boards 14a and 14b is performed by combining the signboard cover 10, the signboard base 13, and the LED module 11.

In other words, after the LED module 11 is formed in close contact with the rear surface of the signboard cover 11 on the front surface of the signboard base 13, the contact surface between the signboard cover 10 and the signboard base 13 is glued. The steps of completing the neon boards 14a and 14b in the form of letters or symbols are carried out by combining them back and forth using a lamp.

When the neon boards 14a and 14b completed in this way are arranged and combined in the form of a predetermined word or sentence, a neon sign-type signboard can be completed.
