Description

[Detailed description of the invention] The present invention relates to a method of manufacturing a display member for a timepiece.

More specifically, it is a method for producing letters and symbols #pictures in a three-dimensional shape for dials, parting plates, day wheel 1st wheel, etc. of watch display members, and The goal is to provide a wide variety of products at low cost that cannot be achieved using conventional methods.

Characters, symbols, marks with current display materials! A typical example of a three-dimensional - dial is the dial.

Since the hour hand O dial is the face of the clock, it is required to have excellent design as well as function, and since it is one of the more expensive watch parts, it is important to find a dial with an excellent design at a low price. The important issue is how to make it. First of all, from the viewpoint of reducing the cost of the current hour hand dial, the first point to be noted is the letter IIO typesetting process.

The current typesetting process for dials involves manually planting 11 or 12 characters per dial on the completed dial base plate, which cannot be mechanized or automated. requires a large amount of man-hours.

Letters, marks @O Typesetting process cannot be mechanized or automated. S* has many letters 0*m, has an irregular shape, is easy to line up, and is warm, and when letters touch each other, they tend to form and have a heavy appearance. This is because automatic material feeding is very difficult due to poor quality.

The current O dial O manufacturing method will be further described with a focus on typesetting knees.

First, the current character OII manufacturing method will be described.

Press the surface of the brass plate with a press to form the character layer and character part. Figure 1-1) 14) Next, punch out the character part with a press, 1i1-1),
S) Next, the letter 1 punched out with a press is barrel polished to remove any burrs from the press punch.

Next, Mi base plating is applied.

Next, cut a diamond on the top of one letter and complete the final plating to complete letter 1. Figure 1-1), RI+O, marks, and window frames are processed in roughly the same way as for letters.

Next, we will explain the process of typesetting the completed characters 1 onto the completed dial base plate 2. First, grasp the manually completed character layer with a bottle picker,
A character layer is inserted into the completed 20-character size dial base board and the character types are created.

Next, the completed dial base board! Glue is poured by hand onto the character layer of the dial base board from the O back, and the true emotion is applied to the completed dial base tube 2.

2g The typesetting process for marks and window frames is done in the same way as the typesetting process for letters.

As mentioned above, the work of manually inserting characters is done by character 1 [
The typesetting of characters is difficult due to the fact that at least 11 characters must be printed on each sheet, and the width and thickness of characters have become smaller due to the diversification of designs. l- is very time consuming and the work is very difficult.

As mentioned above, the present invention eliminates the complexity of the current model of forming letters on a dial into a three-dimensional shape, and also expands the design variety.

That is, the present invention provides a dial plate of a display member for a timepiece, a display W*,
The characters ffi! are placed on cars that have been warmed up for 0 days. , # Watch medal @SO manufacturing method, which features patterns and marks formed into three-dimensional shapes using photosensitive resin and photographic technology.

The following is a review of the method for manufacturing a watch display member according to the present invention.

That is, the present invention provides a timepiece S*t such as a dial, parting board, day wheel 1st wheel, etc., which has three-dimensional O characters, symbols, pictures, and marks of different heights within the same member. , a display member OII manufacturing method for a watch, characterized in that patterns and marks are sequentially formed into a three-dimensional shape using a photosensitive resin using a photographic technique from the lowest height.

The method for manufacturing a timepiece display member of the present invention will be explained in detail.

In the same member, the height is different, for example, the thickness is l2It and a

Finally, there is a photosensitive material III that is not irradiated with ultraviolet rays.
Developed and removed, three-dimensional carved O letters, symbols, test patterns, marks, etc. of different heights are formed on the plastic film of the display member substrate.

The characteristics of this @0 manufacturing method, which forms three-dimensional shapes such as letters, symbols, - patterns, and marks of different heights on the watch display W# mentioned above, are as follows: First, the characters and symbols.

! -The shape of the door is determined by the mask, allowing for free designs and graphic designs.

Moreover, it can be easily drawn using automatic drawing (0mD).

Secondly, since the basic drawing process of the manufacturing method of the present invention is photographic technology, the parts processing and 7
The manufacturing process is very inexpensive because it can be easily and easily mechanized and automated.

Particularly in the case of dials, the effect of cost reduction is very much on original dyeing. In other words, there will be no vegetative work (■) on the characters, and in the conventional method, the letters of the 11th Confucian or 12th ryo, each machined individually, would be typesetting on one dial plate.
This is because, in the case of the present invention, at least 11 or 12 O characters meet at one time.

As described above, the method for displaying the watch according to the present invention** is as follows:
Compared to the conventional method, which mainly involves machining the dial,
It is clear that O brought about innovation in dial manufacturing in terms of design Paraef 4O and Pust.

Furthermore, other display members other than the dial board, such as a parting board,
Letters, symbols, patterns, markings, etc. on the day wheel, day wheel, etc. are currently used in the stamp shoulder method. By taking , a three-dimensional shape O%O can be realized at a low price, making it possible to further increase the commercial value.

The method for manufacturing the hour hand display member will be described in more detail based on an example in which the display member is a dial O.
