Problems solved by technology

However, the size of ordinary film can be made larger, while the size of photopainted film can be made relatively small. The width of photopainted film is generally less than 750mm to achieve the accuracy of ±30μm, and when the width of photopainted film reaches 1000mm, The error will also reach between ±70-80μm
Therefore, it is necessary to consider both size and precision when choosing photo-painting films. It is difficult to meet the precision requirements for large-scale screen production.

Embodiment 1

[0014] Such as figure 1 , figure 2 As shown, a kind of photopainting film splicing method described in this embodiment prepares two spliced ​​films, namely No. 1 spliced ​​film 1 and No. 2 spliced ​​film 2, and then prepares a sleeve film 3; The right side of the film 1 is provided with a row of No. 1 positioning patterns 4 at intervals, a row of No. 1 positioning patterns 4 is arranged on the left side of the No. 2 splicing film 2, and a row of No. 2 positioning patterns is respectively arranged on the left and right sides of the sleeve film 3 5. The No. 1 positioning pattern 4 and the No. 2 positioning pattern 5 are mutually coordinated and positioned, and the No. 1 positioning pattern 4 on the No. 1 splicing film 1 and the No. 1 positioning pattern 4 on the No. 2 splicing film 2 are respectively aligned with the After matching the No. 2 positioning pattern 5 on the set film 3, the No. 1 splicing film 1 and the No. 2 splicing film 2 are butted; brush glue on the set film 3...

Abstract

The invention relates to the technical field of light painting film processing, in particular to a light painting film splicing method which comprises the following steps: preparing two splicing filmsnamely a first splicing film and a second splicing film, and then preparing a positioning film; brushing glue on the positioning film, utilizing the quadratic element to carry out precise positioningand adjust the relative position between the first splicing film and the positioning film; utilizing the quadratic element to carry out precise positioning and adjust the relative position between the second splicing film and the positioning film; after the inspection is approved, fixing and carrying out glue solution curing on the first splicing film, the second splicing film and the positioningfilm; cutting off the redundant positioning films at the two ends; and finally, utilizing a PET adhesive tape to fit the seam of the first splicing film and the second splicing film. According to thelight painting film splicing method, a reasonable splicing method is adopted to carry out high-precision splicing on the two light painting films, so that the spliced film size is increased, and theprecision can reach + / -60 microns.

Description

technical field [0001] The invention relates to the technical field of photo-painting film processing, in particular to a photo-painting film splicing method. Background technique [0002] At present, the film used in the screen making process is generally divided into ordinary film and light painting film. The size error of ordinary film is generally within ±200μm, while the error of light painting film can be within ±60μm. However, the size of ordinary film can be made larger, while the size of photopainted film can be made relatively small. The width of photopainted film is generally less than 750mm to achieve the accuracy of ±30μm, and when the width of photopainted film reaches 1000mm, The error will also reach between ±70-80μm. Therefore, at present, it is necessary to consider both size and precision when choosing an optical film, and it is difficult to meet the precision requirements in the production of large-size screens. Contents of the invention [0003] The ...
