Background
At present, films used in the screen printing plate manufacturing process are generally divided into common films and optical drawing films, the size error of the common films is generally within +/-200 mu m, and the error of the optical drawing films can be within +/-60 mu m. However, the size of the common film is larger, the size of the optical drawing film is smaller, the accuracy of +/-30 μm can be achieved only when the general width of the optical drawing film is less than 750mm, and the error of the optical drawing film can also reach +/-70-80 μm when the width of the optical drawing film is 1000 mm. Therefore, the size and the precision need to be considered when selecting in the light-painting film at present, and the precision requirement in the large-size screen printing plate manufacturing is difficult to achieve.

According to the technical scheme, the first positioning patterns are arranged on the side edges of the first splicing film and the second splicing film, the size of the first splicing film and the second splicing film is generally 750 multiplied by 900mm, the size of the spliced films can reach 150 multiplied by 900mm, the precision error of the first splicing film and the second splicing film after optical drawing can be about +/-30 mu m, and the size of the set position films can also reach +/-30 mu m. Through brushing glue on the set position film, then utilize the cooperation location of a location pattern and No. two location patterns for high accuracy butt joint between a concatenation film and No. two concatenation films, and utilize quadratic element location to detect, can effectively promote positioning accuracy. The precision of the spliced optical drawing film can be controlled to be +/-60 mu m, and the precision of the optical drawing film is ensured.

The design of this structure overlaps through four regions between a positioning pattern and No. two positioning patterns, wherein contains straight line, pitch arc in the overlapping region, and has the condition of mutually perpendicular, the mutual parallel between the straight line, so positioning accuracy between a positioning pattern and No. two positioning patterns is higher to guarantee the precision of the light after the concatenation and draw the film.
The distance between all the first positioning patterns on the first splicing film and the side edge of the first splicing film on the same side is the same, the distance between all the first positioning patterns on the second splicing film and the side edge of the second splicing film on the same side is the same, and the sum of the distance between the first positioning patterns on the first splicing film and the side edge of the same side and the distance between the first positioning patterns on the second splicing film and the side wall of the same side is equal to the distance between two rows of the second positioning patterns on the set position film. The design of the first positioning pattern and the second positioning pattern can effectively improve the efficiency and the precision of positioning matching of the first positioning pattern and the second positioning pattern in the positioning process among the first splicing film, the second splicing film and the set position film.
The first positioning patterns on the first splicing film and the second splicing film are finished with the patterns on the first splicing film and the second splicing film by one-time light painting. The method can effectively ensure the precision of the position of the first positioning pattern on the first splicing film and the precision of the position of the first positioning pattern on the second splicing film, thereby ensuring the splicing precision.
According to the photo-drawing film splicing method, the two photo-drawing films can be spliced in a reasonable splicing mode at high precision, so that the size of the spliced films is increased, and the precision can reach +/-60 mu m.
