JPS5883848A - Manufacture of name plate of acrylic plate using ultraviolet sensitive resin - Google Patents

Abstract

PURPOSE:To prepare a high-quality and low-price acrylic resin name plate, by bringing a positive film into close contact with an acrylic plate coated with a UV sensitive photosensitive resin, and conducting exposure, development, and washing. CONSTITUTION:A positive film on which desired characteristics, or the like are formed is brought into a close contact with an arylic resin plate coated with a UV sensitive photosensitive resin on the surface in a 4-5mum dry thickness, and the photosensitive resin is exposed to UV rays. Then, this resin plate is immersed into a developing soln. of an aq. alkaline soln. to dissolve the photosensitive resin at the exposed areas, and after this development, it is fixed and washed with water.

Description

[Detailed description of the invention] This invention uses a resin that is sensitive to ultraviolet light.

A method for manufacturing acrylic resin nameplates using the photographic method.

Acrylic resin nameplates are used for equipment SO control panels, 1 monitoring panels, 61 production panels, etc. The name or display plate is a manufactured product ordered by the 0 side. Recently, improvements in integrated production methods for these switchboards have progressed rapidly, and 11KCAD, 8Y8TE
While efforts are being made to rationalize M, CAM, and SYSTEMK, the cost of acrylic resin nameplates has not been reduced at all, and improvements are strongly desired.

The conventional method of manufacturing acrylic resin sheets is a mechanical engraving method using a copy engraving machine, which has remained unchanged for the past few decades. In the conventional method, a trained worker carefully traces each stroke of 9 characters on a matrix that serves as a prototype, taking into consideration the spacing and arrangement between each character. Perform cutter movement operations.

It is pre-cut to the finished size. When the back side of the acrylic resin plate is cut <li', inverted characters (orthographic characters when viewed from the front) are created. A paint of any color was carefully injected into the cut portion so that it did not protrude, and after drying, it was usually painted white.

As the Queen's Street 0 is called machine engraving, it is entirely done by hand, so there is no room for labor savings, and the work is done solely by the high level of skill of the workers.
The next nine will cover the cost increase.

There is a limit, and some kind of countermeasure is desired. or.

'Use a rotary cutter to engrave the 0 character shape.

Other than Maru Gothic a, a poor production 1. Being a Noh performer is also a major drawback.

The invention eliminates the above-mentioned table and makes it possible for highly skilled people to
, 5i typeface, the ax width has increased by $%. The purpose of the present invention is to provide a method for producing high-quality, low-cost acrylic resin nameplates.

As an example of the present invention, a large acrylic resin board (the size of 540 to 50 small II boards) was coated with ultraviolet-sensitive resin using a roller coater. , apply evenly to a thickness of 4-5 II/nl O. The work can be done in a bright room, so a dark room.

There is no need for any other special equipment and the 0 work is carried out smoothly. The ultraviolet light-sensitive resin used is 0.0. The exposed part asss.

Several types of dyes are available that give zero color to a colored photosensitive resin.

The fifth step is to create an image of the nameplate that you are going to create.

Create a 1:1 body film in a phototypesetting style.

Finished in a single step. Close contact with the substrate, ultra-stripe pressure,
Exposure to 60 to 908 ee with a water lamp at a distance of 1 m The third step is development, in which the photosensitive resin in the exposed area is dissolved and separated in several minutes by immersion in an alkaline aqueous developer. After this, fix one image and wash it.

It is soaked in a rinsing solution, further washed with water, and dried, and these processes are extremely easy to perform automatically.

The fourth step is to protect one image and clarify one image.

(Conventional) Usually, white paint is applied.

In the fifth step, each nameplate is cut to size, and if necessary, a mounting hole is drilled on the surface, and the nine nameplates are completed using the ultraviolet-sensitive resin of the present invention.

This invention #'i has the following excellent effects when compared with the conventional method of manufacturing acrylic resin nameplates.

b) The letter m (' font) was conventionally only round Gothic, but the acrylic resin nameplate of this invention.

Since any character form can be selected, a nameplate with excellent design can be created, contributing to increasing the attractive value of the user's product.

Mouth) 40 to 50 small nameplates, 5 to 10 large nameplates,
Since it can be manufactured in one go, the labor costs and other costs for one nameplate are minimal, which reduces Ie prices and shortens delivery times.

c) Conventional work requires a highly skilled person, but this invention does not require a skilled person because the machine is easy to operate.

2) Since the conventional method is highly dependent on mechanical processing, a stable, round, high-quality acrylic resin plate without variations can be obtained.
