DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention enables a simple and smooth manufacturing process, reduces manufacturing costs and improves the accuracy of exposure, and simultaneously performs an exposure process on a plurality of stamped surfaces. The present invention relates to a method for manufacturing a stamped surface that can be used and an exposure apparatus used for the method.

[0002]

2. Description of the Related Art Conventionally, there are a number of methods for manufacturing a stamp face, and there is a method for making a stamp face using a flash method. It is made by combining rubber, a positive film with a predetermined stamp pattern or characters, and a carbon film, and using a stamp rubber that receives a flash, using a flash based on the principle of photography to project light and heat, Is adhered to portions other than the stamp surface pattern of the stamp surface rubber. Thus, when the stamp rubber is fixed to the holder and stamped, the ink injected into the stamp oozes out from the stamp pattern portion appropriately, and the stamp pattern can be stamped accurately.

[0003] A conventional method of manufacturing a stamp face is shown in FIG.
As shown in FIGS. 7 and 8, an exposure method of projecting from below to above with a flash is adopted, and a glass plate having a large area on an exposure apparatus (50) on which the flash (51) is mounted at the bottom. (40) is set up, a positive film (41) having a stamp surface pattern or characters formed by photoengraving is prepared, and an exclusive acrylic plate having a small opening (421) in the center corresponding to the size of the stamp stamp surface is prepared. Using a jig (42) and a positive film (41)
Is adhered to the large opening on the bottom surface of the special jig (42) with cellophane tape, and a carbon film (43) is arranged on the positive film (41).
After placing a thin rubber for test (44) and a thick rubber for operation (45) cut to the same size as the small opening (421) in 2), the glass plate (40) on the flash (51) is placed. ), The positive film (41) is aligned with the flash (51), the exclusive jig (42) is fixed from above by the pressing member (46), the upper lid (52) is closed, and the flash (51) is closed. ) Is turned on to expose the thin rubber (44), and then the test stamp rubber is taken out and the completed stamp is inspected.

Then, after confirming that the font face and the pattern are clearly displayed, a glass plate (40) having a large area is set on the exposure device (50) again, and the positive film (41) is removed. Special jig (4)
2) a carbon film (43) is placed on a positive film (41),
From above the small opening (42) in the special jig (42)
After arranging the thick rubber (45) cut into the same size as that of 1), the exclusive jig (42) is arranged on the glass plate (40) and the positive film (41).
Is aligned with the flash (51), and the holding member (4
6) and a holding plate having the same thickness as the thin rubber (44), the exclusive jig (42) is fixed from above, the upper lid (52) is closed, and the energizing switch of the flash (51) is turned on to turn on the thick rubber (44). 45) is exposed, and then the rubber stamp is removed, and the completed stamp is inspected. Then, after confirming that the stamp font and pattern are clearly shown, the stamp rubber is attached to the holder and attached to the PE paper holder stamp, and the adjacent edge between the stamp rubber and the holder by a hot melt machine. Shield (edge welding). When the shield is finished, test for leaks by blowing air from the ink inlet with your mouth to make sure it is completely in contact. If they are not completely adhered, repair them with a hot melt agent and then inject ink into the stamp. (When injecting ink, be sure to perform at a temperature of 25 ° C or more. If the temperature is too low, heat it to increase the temperature).

[0005] However, the above-described method and apparatus for manufacturing a stamp stamp face has the following drawbacks during manufacture. 1. Since the manufacturing process is complicated, the manufacturing cost is high, and at the same time, the stamp rubber is arranged on the glass plate,
It is difficult to accurately align and project on the flash. Therefore, it is necessary to manufacture a large stamping rubber, and after the exposure, it is necessary to cut the rubber and then adhere it to the holder. 2. Since only one stamp stamp can be manufactured at a time, the stamp stamp productivity is very poor. 3. After the production of the stamped surface, a leak test is performed by blowing air into the ink inlet with the mouth of the holder to confirm that there is no leak, and the ink must be injected by the stamped surface manufacturer himself. So the work is very inconvenient. 4. Since the manufacturer must purchase a stamping surface exposure apparatus and a hot melt machine for bringing the stamping surface into close contact with the holder, the equipment cost increases as a result.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems. By exposing a stamp surface rubber mounted on a holder, the manufacturing process can be performed easily and smoothly, the manufacturing cost can be reduced, and the flash can be further reduced. The exposure area can be within the range of the stamp inner frame by using the projection method from above to below and the method of limiting the negative film, the transparent film and the glass plate with the outer frame of the stamp, and the accuracy is high. Can be increased. Further, at the time of shipping the semi-finished product of the stamp, since the injection of the ink and the prevention of the leakage are already performed, the manufacturer does not need to further inject the ink. Further, in the exposure apparatus of the present invention,
Since the adjustment can be made according to the size of the stamp and the exposure process can be performed on a plurality of stamp surfaces simultaneously, the manufacturing efficiency of the stamp stamp surface can be improved.
