Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, the present invention is described further:
As shown in figs. 1-7, for the manufacture method of leaf type film group, comprise the following steps:
Step A: prepare first film 1 and second film 2; Wherein, the both sides of described first film 1 are equipped with the first target 11, and the quantity of the first target 11 of the wherein side of first film 1 is more than the quantity of the first target 11 of opposite side; Described second film 2 is provided with and each first target 11 several second targets 21 one to one; Described first target 11 and the second target 21 all include around respective central point in the transparent area 3 that is arranged alternately with light-blocking region 4; The region that described second target 21 is corresponding with the transparent area 3 of the first target 11 is set to light-blocking region 4, and the region that the second target 21 is corresponding with the light-blocking region 4 of the first target 11 is set to transparent area 3;
Step B: by first film 1 and second film 2 by medicine face in opposite directions in the way of closing, and make each second target 21 be right against the first target 11 of correspondence, the transparent area 3 of the second target 21 is right against the light-blocking region 4 of corresponding first target 11, and the light-blocking region 4 of the second target 21 is right against the transparent area 3 of corresponding first target 11; Wherein, according to known general knowledge, the medicine face of the film is the film and sets figuratum one side;
Step C: when the relative position of first film 1 and second film 2 remains unchanged, first film 1 is connected with second film 2 formation leaf type film group, that is, after first film 1 and the second film 2 para-position in stepb, and in step C, the relative position being connected to first film 1 and second film 2 of first film 1 and second film 2 carries out when remaining unchanged so that first film 1 and second film 2 still keep accurate contraposition.
The present invention is when first film 1 and the second film 2 closing, owing to the quantity of the first target 11 of the wherein side of first film 1 is set to the quantity of the first target 11 more than opposite side, and by making each second target 21 be right against the first target 11 of correspondence, first film 1 and second film 2 can be avoided anti-loaded; And the light-blocking region 4 of corresponding first target 11 it is right against in conjunction with the transparent area 3 of the second target 21, the light-blocking region 4 of the second target 21 is right against the transparent area 3 of corresponding first target 11, the accurate contraposition of first film 1 and second film 2 can be realized, thus, the present invention can effectively solve first film 1 and second film 2 is anti-loaded, para-position is inaccurate problem.
Wherein, described first target the 11, second target 21 may be configured as the shapes such as rectangle. And the quantity of transparent area 3, light-blocking region 4 can be arranged according to actual demand. Preferably, described first target 11 is rounded, and the first target 11 includes two transparent areas 3 and two light-blocking regions 4; Each transparent area 3 of described first target 11, each light-blocking region 4 all account for 1/4th of the area of the first target 11. Described second target 21 is rounded, and the second target 21 includes two transparent areas 3 and two light-blocking regions 4; Each transparent area 3 of described second target 21, each light-blocking region 4 all account for 1/4th of the area of the second target 21. By rationally arranging first target the 11, second target 21, the structure that can make first target the 11, second target 21 is relatively simple, it is convenient to make, and, after first film 1 and the second film 2 closing, if observing, there is light therethrough the junction of adjacent transparent area 3 and light-blocking region 4, then it represents that the region that the respective regions of the second target 21 is corresponding with the first target 11 offsets, not positive alignment, thus perusal the first target 11 and the second target 21 alignment condition can be convenient to.
Preferably, in step C, described first film 1 is connected formation leaf type film group with the same side of second film 2 by double faced adhesive tape.
Wherein, the quantity of the first target 11 of the both sides of first film 1 can set according to actual demand. Preferably, the wherein side of described first film 1 is provided with three the first targets 11, and two of which the first target 11 is positioned at the two ends of first this side of the film 1; The opposite side of first film 1 is provided with two the first targets 11, and these two the first targets 11 lay respectively at the two ends of first this side of the film 1, thus can further improve the convenience of first film 1 and the second film 2 para-position, and are convenient to processing and fabricating.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various corresponding changes and deformation, and all these change and deformation all should belong within the protection domain of the claims in the present invention.
