JPS604094A - Working method for indicating key - Google Patents

Abstract

PURPOSE:To contrive to enhance productivity and to reduce cost, by a method wherein an upper surface of a key base molded from a resin having a desired color is coated with a coating material of another desired color, and the coated film is irradiated with a laser beam to expose the key base in the shape of a desired character or the like. CONSTITUTION:A coated key base is prepared, and it is fitted to a pre determined position of a keyboard, whereby the coated film can be irradiated with a laser beam even after assembling the keyboard. The step of indicating a character or the like, namely, marking by irradiating with the laser beam is performed after fitting keys into the keyboard, whereby merits are remarkably augmented. Marking can be performed by using a known laser marker or laser machine tool. Although marking is conducted ordianarily at a rate of one mark per one pulse when using a carbon dioxide gas laser marking maching of the pulse-oscillating system, several times of beam irradiation sre required for one mark here, since the coated film on top of the key is thick.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for processing indicators displaying letters, numbers, symbols, etc. This article relates to a method of processing an extremely durable indicator that allows letters, etc. to be displayed on the top surface in an extremely simple manner, and that does not deteriorate due to wear and tear even after repeated use over many years. be.

Conventionally, in order to mark letters etc. on the top surface of a computer, etc., a two-color molding machine was generally used. It has been adopted.

After printing, it is necessary to protect the displayed characters by applying a UV transparent clear coat with a smear or the like.

In addition, in the conventional method, for example, when displaying characters on the upper surface of the + and -, that is, the top of the top, it is necessary to display predetermined characters, etc. on each board before incorporating them into the board. It is impossible to display characters, etc. after incorporating the board into the board. Therefore, it takes a considerable amount of time and effort to place the six cows displaying predetermined characters, etc., at predetermined positions on the cow board.
It takes a lot of effort and expense to complete the board.

The present invention provides a display processing method for indicators that eliminates the above-mentioned drawbacks, and is a combination of the Shisamershiji method and the painting method.

The gist of the invention is to mold a cow-base using resin of a desired color and to mold the cow-base at least 1 m above the cow-base.
Apply another 19T paint of the desired color to form a coating film,
The method of processing an indicator involves exposing the ten-base in the shape of a desired character or the like by irradiating the coating film with a laser beam.

The present invention will be explained in more detail below.

As the base material of the indicator used in the present invention, resins such as ABS%PB'l' used for ordinary indicators can be used, and these resins are molded by a known one-color molding method. That is, a ten-base is molded using a resin material of a desired single color, such as display characters of black, white, red, green, yellow, etc. Therefore, during molding, the work of changing the color of the resin, which was frequently required in the conventional method, is reduced, and therefore productivity is improved. In addition, the total mold cost is greatly reduced, especially compared to the two-color molding method.

The 10-base molded with a resin of a desired single color is exposed and revealed as letters, etc. by removing the coating film by irradiation with the laser J-6 as described later, so the color of the 10-base becomes the color of the letters, etc. A paint film of a desired color different from the color of the base material is applied to the surface, at least the upper surface, by means of a paint brush or the like. Next, this coating film is irradiated with a laser beam to expose the underlying surface as desired characters, etc. In this way, for example, white characters or the like are displayed on a black top.

Although it is preferable to keep the thickness of the coating film constant, the number of laser irradiations can be easily controlled, so the thickness of the coating film does not vary.

-1, 10- The coating film formed on the top is directly struck by the operator's hands, so it needs to have a thickness that satisfies the strength standards for use. For example, it is preferable to set the distance to 0.03 m+ to 0.06 m. In addition, as a paint, it has a high strength EVO +
It is preferable to use a two-component paint or a UV paint whose main component is resin or the like.

According to the present invention, a coated base is prepared in advance, it is assembled at a predetermined position on the board, and the laser beam 6 is irradiated even after the board is assembled. is possible. The advantages of the present invention are significantly increased by performing the display of characters, etc. by irradiation with laser beams, that is, the marking process after the marking board is assembled. Marking can be done using a known laser marker or laser processing machine, but a pulse oscillation type carbon dioxide laser marking machine usually has 1 mark/1 mark.
Mark jig is performed at pulse speed, but in the case of the method of the present invention, the blood film on the top of the mark is thick, so it is necessary to irradiate one mark several times.

In addition, when using a continuous wave carbon dioxide laser processing machine, all the marks on the board are marked using a copper plate mask and the marking jig is completed continuously.

The ten tigers installed on the cow board are lined up at various pitches and angles, and the horizontal and vertical positions can be automatically controlled by jigging them with a laser beam that shines from above. It is necessary to place a +-horde on top of the moving tool.

This tool is controlled and the top is shifted to perform a merging jig, but the program is input to the cosipulator device, so even if the type of board changes, the setup time is short. It can be used for high-plant, low-volume ten-board production.

Laser marker sticker) (version) Since changing the size according to the size of the laser marker does not increase the striking force, it is possible to change the size continuously, such as the one used when shooting. It is preferable that the system be used and controlled simultaneously with one cow by a cosiputer.
