Abstract
The invention discloses a method for cutting a polarizer, comprising the following steps of firstly taking a benchmark vertex as a benchmark and taking the precision Delta d requested by a small polarizer as a stepping to determine a first cutting position, calculating by n times circularly till the value of multiple of n-1 and Delta d is more than or equal to the second edge of the small polarizer; sequentially cutting the first edges of the small polarizer on the large polarizer during every cutting process and cutting the large polarizer as bar-shaped polarizers; arranging all bar-shaped polarizers with the inclined-edge and low position points aligned; cutting the second edge of the small polarizer in a direction vertical to the first edge, thus cutting the small polarizer; counting the amount M1 to Mn of the small polarizers cut from first time to nth time; and taking the distance of the maximum value Mmax and the benchmark vertex as the first best cutting position so as to cut the large polarizer into the small polarizers. The method improves the effective utilization ratio of the polarizer.
Description
Technical field
The present invention relates to a kind of method that cuts polaroid, relate in particular to a kind of method that cuts LCD with polaroid.
Background technology
Along with development of science and technology, the application of LCD in people's life more and more widely, but the starting material of LCD, especially the core technology of polaroid is always by abroad being grasped, therefore, the price of polaroid is high always, makes the cost of polaroid account for 1/3 of liquid crystal display modulator material total cost, even over half.
LCD is the big polaroid of opening with the starting material of polaroid, is the big polaroid of opening of 1000mm * 500mm as length and width.Production of liquid crystal displays merchant cuts the big polaroid of opening according to the size of self product, because the relation of visual angle and product background color, Xiao Zhang's polaroid all can have certain included angle with the big polaroid of opening when cutting, and forms a lot of corners thereby cut the back.Production of liquid crystal displays merchant generally takes the mode that cuts as shown in Figure 1, be about to big polaroid 1 cuts out Xiao Zhang's polaroid 2 earlier along the angle a of needs the long limit 5 of opening, to open the broadside 4 that cuts Xiao Zhang's polaroid 2 behind polaroid 1 half-twist more then greatly, the effective rate of utilization of the Xiao Zhang's polaroid that cuts so generally all has only 70%～80%.
Because the cost of polaroid is than higher, therefore, the effective rate of utilization that how can farthest improve polaroid becomes the problem that a lot of production of liquid crystal displays merchants often consider.
Summary of the invention
The objective of the invention is to solve the low problem of effective rate of utilization that exists at the existing cutting method of polaroid, a kind of cutting method that can improve the polaroid effective rate of utilization is provided.
The technical solution adopted in the present invention is: a kind of polaroid cutting method comprises the steps
(1) at first, determine the big distance of opening polaroid benchmark summit of the first best cutter spacing distance down, the method for determining is as follows:
(a) be that first time cutter spacing calculated with the benchmark summit, cut according to the visual angle and the size of needed Xiao Zhang's polaroid;
(b) on the big first kind limit that cuts out Xiao Zhang's polaroid on the polaroid successively of opening, will open polaroid greatly and be cut into the strip polaroid; With all strip polaroids of cutting according to the arrangement of aliging of the mode of its hypotenuse low level end points alignment; Cut out the second class limit of Xiao Zhang's polaroid along the direction vertical, and then cut out Xiao Zhang's polaroid with first kind limit;
(c) the quantity M1 of Xiao Zhang's polaroid of cutting out for the first time of statistics;
(d) being benchmark with the benchmark summit, is that remaining first time cutter spacing is determined in stepping with the precision prescribed Δ d of Xiao Zhang's polaroid, and cycle calculations n time stops to calculate during more than or equal to the second class limit of Xiao Zhang's polaroid up to the value of (n-1) * Δ d; Circulation cuts successively according to the method in the step (b), and calculates for the second time to the quantity M2 to Mn of the Xiao Zhang's polaroid that cuts out for the n time, determines the maximal value Mmax among the M1 to Mn.
(e) determine maximal value Mmax pairing with the distance benchmark summit be the first best cutter spacing down;
(2) begin to cut with the first best cutter spacing down, will open polaroid greatly according to the method in the step (b) and be cut into Xiao Zhang's polaroid.
Preferably, described first kind limit is the long limit of Xiao Zhang's polaroid, and the second class limit is the broadside of Xiao Zhang's polaroid.
Preferably, finish described step (1) by computer program simulation.
Beneficial effect of the present invention is: the effective rate of utilization of opening polaroid greatly can be increased to more than 90%, save material cost.

Embodiment
Now in conjunction with the accompanying drawings the specific embodiment of the present invention is described in detail.
As shown in Figure 2, a big polaroid 1 of opening is 1000mm as its long L, and wide W is 500mm, it need be cut into the long 40mm that is, wide is 20mm, and visual angle a is 60 °, precision prescribed Δ d is Xiao Zhang's polaroid 2 of 0.05mm, and then according to polaroid cutting method of the present invention, its cutting step is as follows:
(1) at first, determine the big distance h of opening the benchmark summit 6 of polaroid 1 of the first best cutter spacing distance down, the method for determining is as follows:
(a) be that first time cutter spacing 3 calculated with benchmark summit 6, cut according to the visual angle and the size of needed Xiao Zhang's polaroid 2;
(b) on the big first kind limit that cuts out Xiao Zhang's polaroid 2 on the polaroid 1 successively of opening, select to cut earlier the long limit 5 of Xiao Zhang's polaroid 2 at this, promptly described first kind limit is length limit 5, is cut into as shown in Figure 3 strip polaroid with opening polaroid 1 greatly; As shown in Figure 4, with all strip polaroids of cutting according to the arrangement of aliging of the mode of its hypotenuse low level end points 7 alignment; Cut out the second class limit of Xiao Zhang's polaroid 2 along the direction vertical with long limit 5, promptly broadside 4, and then cut out Xiao Zhang's polaroid 2;
(c) the quantity M1 of Xiao Zhang's polaroid 2 of cutting out for the first time of statistics;
(d) as shown in Figure 2, with benchmark summit 6 is benchmark, with 0.05mm is that remaining first time cutter spacing 3 is determined in stepping, cycle calculations n time, stop to calculate during more than or equal to the broadside 4 of Xiao Zhang's polaroid up to the value of (n-1) * 0.05, promptly n gets 401 times in the present embodiment, and first time cutter spacing 3 calculating is 0.05mm apart from the distance h on benchmark summit 6 so for the second time, distance h when calculating for the third time is 0.1mm, and the like; Circulation cuts successively according to the method in the step (b), and calculates for the second time to the quantity M2 to Mn of the Xiao Zhang's polaroid that cuts out for the n time, determines the maximal value Mmax among the M1 to Mn, and maximal value Mmax is 587 in the present embodiment.
(e) determine that the pairing distance h apart from benchmark summit 6 of maximal value Mmax (generally between 17.32mm to 17.42mm or 18.57 to 18.67mm) is a cutter spacing under first the best;
(2) begin to cut with the first best cutter spacing down, will open polaroid 1 greatly according to the method in the step (b) and be cut into 587 Xiao Zhang's polaroids 2.
The aforementioned calculation first best process of cutter spacing down, promptly step (1) can be finished by computer program simulation.
If cut Xiao Zhang's polaroid 2 of above-mentioned requirements according to prior art, can cut out 587 Xiao Zhang's polaroids 2, general cutting method can only cut out 540 to 550 Xiao Zhang's polaroids 2, this shows, adopts cutting method of the present invention to cut the effective rate of utilization that has improved polaroid.
Only being preferred embodiment of the present invention in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should belong to technology category of the present invention.
