Description

Indicator coating method and coating system {Indicator coating method and coating system}

The present invention relates to an indicator painting method and a painting system, and more specifically, by improving the symbol part painting method of the indicator into a partial printing method, it is possible to reduce the amount of paint and increase work efficiency, and to improve the foreign matter removal part of the painting system. This is a technology related to indicator coating method and coating system that can improve painting quality by completely removing foreign substances.

In general, in the case of mass-produced goods, almost all goods undergo a painting process to add color to the surface.

This is to protect the surface of the product from corrosion or damage and at the same time provide aesthetics by the painted color. Typically, the product to be painted is fixed with a jig and then a paint such as paint is sprayed on the area to be painted to create a coating layer. forms.

Among these coating methods, there is a liquid coating method. Painting using a liquid coating method includes a method of applying paint to the surface of an item using a paint brush, and a spray method of applying paint by spraying paint with a spray gun.

Among the above-mentioned liquid coating methods, the method of using a brush has the problem that the thickness of the painted surface is uneven as paint is applied to the surface of the article using a brush, and the final quality of the painting is not uniform, so it is applied to the painting system. This made it difficult to use.

When painting is carried out by spraying paint on the entire surface of the product using a spray gun, it has the advantage of improving the problem of painting using a brush and forming an even thickness on the painted surface, so it is widely used in painting systems. there is.

When painting an indicator equipped with display parts such as the symbol part and indicator light position using a conventional spray gun, a jig is installed at the indicator lamp position, white paint is applied to the entire surface, and the applied white paint is dried. After removing the jig and applying the final color paint, when the final color paint dries, the final color paint is removed using a laser to suit the shape of the symbol part and the shape of the indicator light position part, forming the shape of the symbol part and the indicator light position part.

At this time, in order to form the indicator light position, a jig is installed at the indicator light position and then white paint is applied to the entire surface. When the applied white paint dries, the jig must be removed, making the work process complicated and reducing efficiency. There was a problem in that white paint was wasted due to the paint being applied to the entire surface.

In addition, even though it is the same product, depending on the region (tropical region, polar region, etc.), the symbol part and indicator light position of the indicator may be different or some functions may not be formed. In this case, the white paint is applied to the entire surface of the indicator. There was a problem in that the efficiency of the painting process was greatly reduced due to the process of installing and removing a jig at the indicator light position appropriately set for each region.

In particular, if the position of the indicator light was changed or the jig was installed incorrectly after the final color paint was applied, there was a problem that the painting work had to be restarted after removing all the applied paint.

In addition, when applying paint using a brush or spray method, if painting is performed without completely removing dust or foreign substances from the surface of the article, the quality of the painted surface may become inconsistent due to dust or foreign substances. There were also problems forming.

Therefore, in the indicator painting method in which the symbol part and the indicator light position part are formed, the problem of waste of paint caused by applying white paint to the entire surface to form the symbol part and the indicator light position part is solved and the indicator light position part is formed. There is a need to improve the process according to the installation and removal of jigs and to develop an indicator coating method that can ensure uniform painting quality by completely removing dust or foreign substances remaining on the surface of the product before applying paint.

Hereinafter, the technical idea of the present invention will be described in more detail using the attached drawings. The attached drawings are merely examples to illustrate the technical idea of the present invention in more detail, so the technical idea of the present invention is not limited to the form of the attached drawings.

Hereinafter, the indicator coating method according to the present invention will be described in detail with reference to FIGS. 1 to 10.

Figure 1 is a flow chart showing the overall sequence of the indicator coating method according to the present invention.

The indicator painting method according to the present invention is a method of painting the indicator (A) using the painting system (1).

This indicator coating method can obtain a subject to be coated with a certain quality by performing painting using the coating system 1, and applying negative static electricity to the dust removal member 23 through the static electricity generator 27 to produce an indicator. By adsorbing and removing dust remaining on the surface of (A) by static electricity, the dust brushed off by the brush 231 of the dust removal member 23 is prevented from scattering into the air and is prevented from reattaching to the indicator (A). This is to improve the quality of the paint.

In addition, by printing only the symbol part (S) of the indicator (A) with white ink, the process of applying white paint to the entire surface of the conventional indicator is omitted, thereby reducing white paint and improving the indicator (A) painting process. will be.

In addition, instead of applying white paint to the entire surface of the indicator (A) to form the symbol part (S), only the symbol part (S) is printed with white ink or ink of another color, thereby creating a light position part (R) on the indicator. ) This is to increase the efficiency of the painting process by significantly shortening the work process by eliminating the need to install a jig to form the paint.

In addition, since white paint is not applied to the entire surface of the indicator (A) when forming the symbol part (S), the final color paint only needs to be removed from the part where the indicator light position part (R) is to be formed with a laser. The indicator light position part (R) is formed, so the process of installing or removing a jig to form the indicator light position part (R) is omitted, and after applying the final color paint, the indicator light position part (R) is formed. This is to enable the indicator light location portion (R) to be easily formed in the indicator even if it is changed or needs to be formed additionally.

In this way, the indicator coating method of the present invention can be applied not only to indicators but also to various articles to obtain excellent quality coated objects.

This indicator coating method includes an article input step (S10), a first foreign matter removal step (S20), a symbol portion printing step (S30), a final color paint application step (S40), a drying step (S50), a symbol portion, and an indicator light. It includes a forming step (S60) and an article discharging step (S70), and the above-described indicator painting method can be painted using a painting system (1) capable of painting.

Referring to FIG. 2, the painting system 1 includes an article input unit 10, a conveyor C, a first foreign matter removal unit 20, a symbol printing unit 30, and a second foreign matter removal unit 20'. , a paint application unit 30', a drying unit 40, and an article discharge unit 50, and may further include a paint removal unit 60 and a polish application unit 70, if necessary.

The product to be painted can be input into the product input unit 10.

A conveyor (C) is installed in the product input unit 10 to transport products along the transfer line, so that the inserted products can be gradually transferred along the transport line.

This conveyor (C) is installed across all configurations, which will be described later, to form an overall transport line and to transport items placed on the conveyor at a uniform speed.

A first foreign matter removal unit 20 may be formed on one side of the product input unit 10. The first foreign matter removal unit 20 can remove dust or foreign matter attached to the surface of the goods that are introduced through the goods input unit 10 and transported along the transfer line through the conveyor (C).

A symbol printing unit 30 may be formed on one side of the first foreign matter removal unit 20. The symbol portion printing unit 30 is configured to print the symbol portion (S) with white ink and paint of the final color of the symbol portion (S) before applying the final color paint to the entire portion of the product.

Accordingly, the symbol portion (S) is configured to print the symbol portion (S) that appears by partially removing the final color paint by the paint removal portion 60, which will be described later.

At this time, if the symbol part (S) is the commonly used white color, the symbol part (S) is printed with white ink. If the symbol part (S) is a color other than white, the symbol part (S) is printed with white ink. After printing (S), the symbol part (S) of the color desired by the user can be printed by additionally printing the final ink of the symbol part (S) of another color selected on top of the white ink of the printed symbol part (S).

By printing this symbol portion (S) with ink, there is no need to apply white paint to the entire surface of the indicator (A) to form the symbol portion (S) on the indicator (A). , only the symbol part (S) of the indicator (A) is printed with white ink, or the final color ink of the symbol part (S) is additionally printed with the selected final color ink on top of the white ink of the symbol part (S) printed with white ink. By forming the symbol part (S) of the color desired by the user, painting materials can be saved by not using white paint, and the efficiency of painting work can also be increased.

In addition, by printing the symbol part (S) with white ink or other color ink, the indicator light position part (R) can be formed on the indicator (A) without installing a jig at the part where the indicator light position part (R) is to be formed. It becomes possible to form (R), greatly increasing the efficiency of painting work.

In addition, the location and type of the indicator (A) provided in the vehicle may vary depending on the region in which the vehicle is operated.

For example, in tropical regions where all seasons are hot, vehicles do not need to be equipped with heaters, but in non-tropical regions, vehicles must be equipped with heaters, and in vehicles equipped with heaters, the indicator (A) has the heater symbol (S) and Although the indicator light position part (R) must be formed, the heater symbol part (S) and the indicator light position part (R) do not need to be formed in the indicator (A) in a vehicle that is not equipped with a heater.

At this time, when painting an indicator of the same vehicle model, when painting the indicator (A) of a vehicle that is not equipped with a heater, white paint is applied to the entire surface without installing a jig at the indicator light location part (R) of the heater. When painting the indicator (A) of a vehicle equipped with a heater, a jig was installed at the indicator light location (R) of the heater and then white paint was applied to the entire surface.

Due to this, the worker thought that the vehicle was not equipped with a heater and did not install a jig at the indicator light location (R) of the heater when painting the indicator (A), but instead applied white paint to the entire surface and then painted the vehicle with a heater. When I found out that it was an indicator (A) being installed, there was the inconvenience of having to remove all the paint, reinstall the jig at the indicator light location (R) of the heater, and apply white paint to the entire surface.

However, by printing the symbol part (S) with white ink or ink of the final color, the indicator light position part (R) can be formed on the indicator (A) without installing a jig at the part where the indicator light position part (R) is to be formed. As (R) can be formed, the inconvenience of having to install a jig according to the forming position of the indicator light position (R) of the indicator (A) is eliminated, and the display of the indicator (A) is maintained even after the final color paint is applied. Even if the back position part (R) needs to be changed, omitted, or added, the symbol part (S) and the indicator light position part (R) can be easily formed in the indicator (A).

Therefore, in the present invention, when forming the symbol part (S) and the indicator light location part (R) in the indicator (A), only the symbol part (S) is printed with white ink, so that the entire indicator (A) is coated with white paint as in the past. As this does not need to be done, the process of installing or removing a jig in the area where the indicator light location portion (R) is formed is omitted, thereby increasing the efficiency of the painting process.

In addition, in the symbol part and indicator light position forming step (S60), which will be described later, the final color paint can be selectively removed using a laser to form the symbol part (S) and the indicator light position part (R), thereby forming the final color paint. Even after application, even if the formation position of the symbol part (S) and indicator light position part (R) of the indicator (A) is changed or needs to be omitted or added, the position of the symbol part (S) and indicator light position on the indicator (A) is easily maintained. It was possible to form a division (R).

A second foreign matter removal unit 20 may be formed on one side of the symbol printing unit 30.

The second foreign matter removal unit 20' prepares the application of the final color paint by removing dust or foreign substances attached to the surface of the article after the symbol part S is printed with white ink through the symbol part printing part 30. You can do it.

Therefore, by removing dust or foreign substances through the second foreign matter removal unit 20' and then applying the final color paint, better painting quality can be obtained.

The above-described first foreign matter removal unit 20 and the second foreign matter removal unit 20' may have the same configuration, and their specific configuration will be described later.

A paint application portion 30' may be formed on one side of the second foreign matter removal portion 20'.

The paint application unit 30' is configured to apply the final color paint to the entire surface of the article on which the symbol part S is printed with white ink.

It is desirable to use the paint application portion 30' to uniformly apply the paint to the surface of the article through spraying.

A drying part 40 may be formed on one side of the paint application part 30'. The drying unit 40 may be formed as a device that can dry an article coated with paint, such as an oven.

An article discharge unit 50 may be formed on one side of the drying unit 40. The article discharge unit 50 is configured to complete the painting process by discharging articles on which paint application and drying have been completed.

Additionally, a paint removal unit 60 and a polish application unit 70 may be further formed between the drying unit 40 and the article discharge unit 50, if necessary.

The paint removal unit 60 is equipped with a laser and forms the shape of the symbol part (S) or the indicator light position part (R) by partially removing the final color paint through laser irradiation. That is, the final color paint is removed with a laser along the shape of the symbol part (S) or indicator light position part (R) preset by the laser of the paint removal part 60, and the symbol part (S) or indicator light position part (R) is removed. ) is formed.

At this time, in order to change the color of the symbol part (S) to a color other than white, reprint ink of a different color on the symbol part (S) printed with white ink, then apply the final color paint, and then apply the final color paint. When removed with a laser, a symbol part (S) of a different color is exposed and formed.

The polish application unit 70 is configured to apply a polish to the surface of an article on which paint has been applied, and has the effect of improving the texture of the paint on the surface of the article, thereby increasing aesthetics and usability.

This coating system 1 can be applied to various items in addition to the indicator coating method of the present invention, which will be described later.

Hereinafter, the indicator coating method according to the present invention will be described in detail with reference to FIGS. 1 to 10 and the above-described coating system 1.

The product input step (S10) is a step of inputting the indicator (A) through the product input unit (10).

In the product input step (S10), the indicator (A) is input into the product input unit 10 through the conveyor (C) installed across the product transfer line.

Therefore, the indicator (A) is gradually transferred to the transfer line through the conveyor (C) and painted through the steps described later.

After the product input step (S10), the first foreign matter removal step (S20) may be performed.

The first foreign matter removal step (S20) is a step of removing dust or foreign matter remaining on the surface of the indicator (A) transferred to the first foreign matter removal unit 20 through the conveyor (C).

That is, the first foreign matter removal step (S20) is a pretreatment step before full-scale painting of the indicator (A) and is a step of removing dust or foreign substances attached to the surface of the indicator (A).

Through the first foreign matter removal step (S20), the surface of the indicator (A) is cleaned to a state suitable for painting, allowing the painting quality of the indicator (A) to be further improved.

After the first foreign matter removal step (S20), a symbol portion printing step (S30) may be performed.

The symbol portion printing step (S30) is a step of printing only the symbol portion (S) of the indicator (A), that is, the symbol portion (S) that displays each function on the indicator (A), with white ink.

The symbol part printing step (S30) prints only the symbol part (S) with white ink, thereby saving the use of white paint generated by applying white paint to the entire indicator (A) in the conventional painting method, thereby avoiding excessive use of paint. This not only prevents the environment from being polluted, but also increases economic efficiency by reducing the use of paint.

At this time, when it is desired to form the symbol portion (S) in a color other than white, a step of printing ink of another color on the symbol portion (S) printed with white ink may be further included. After printing more ink of a different color on the symbol part (S) printed with white ink, the final color paint is applied. After drying, the final color paint is removed with a laser, and the symbol part (S) of a different color is exposed. A symbol part (S) of a color other than white is formed.

After the symbol portion printing step (S30), a second foreign matter removal step (S80) may optionally be further performed.

In the second foreign matter removal step (S80), dust or foreign matter remaining on the surface of the indicator (A) on which the symbol part (S) is printed in the symbol part printing step (S30) is removed through the second foreign matter removal unit (20'). As a removal step, dust or foreign matter that has accumulated on the surface of the indicator (A) during the symbol part (S) printing process is removed, and the final color paint is applied evenly to the indicator (A) before applying the final color paint. This is the step of pre-treating the surface again.

Therefore, by additionally performing the second foreign matter removal step (S80), more improved painting quality can be obtained.

After the symbol portion printing step (S30) or after the second foreign matter removal step (S80), a final color paint application step (S40) may be performed.
