Description
Technical field
The present invention relates to polaroid technical field more particularly to a kind of cutting methods for promoting polarizer material utilization rate.
Background technique
Currently, cutting into finished product standard size by polarizer material, there are two types of approach, first is that direct by coiled strip guillotine
Cut into finished size；Second is that cutting into master slice by coiled strip guillotine, end product rule is then cut by master slice guillotine again
It is very little.But during cutting, due to the limitation of finished size, it is excessive to often lead to cut remaining leftover pieces, causes material
Utilization rate is relatively low, virtually increases material cost.Stock utilization refers to that the material quantity for including in qualified product is (former in material
Material) specific gravity shared in total flow, that is, the ratio between the material of the material and actual consumption that have been utilized illustrates that material is effective
The degree utilized.It is one of the index for reflecting material Quality degree of effective utilization.Contained material in stock utilization product
Nt wt net weight accounts for the ratio of its consumption to indicate, calculation formula is as follows:
There are mainly two types of the methods for promoting polarizer material utilization rate at present, first is that during making cutting cutter die,
Make cutting die consistent with material wide cut as much as possible, maximizes utilization rate；Second is that during master slice is cut, according to finished product
Size, which specifically calculates, cuts several column of several rows, to reach utilization rate maximization.By the promotion of stock utilization, reduce product at
This.
It is cut in addition, existing master slice cuts the absorption axiss angle that scheme is foundation coiled strip, so that obtaining finished product needs
The angle wanted.Because of the various angles of customer demand: 0 °, 7 °, 45 °, 83 °, 90 °, 97 °, 135 °, 173 ° etc., often coiled strip is cut into
During master slice, the specification that the master slice of equal angular is cut out be it is single, in this way when cutting various sizes of finished product small pieces,
Different degrees of leftover pieces will be generated, the waste of material is caused, so that the reduction that utilization rate is different degrees of.
As shown in Figs 1-4, two kinds of wide cuts for cutting mode its material are all single, are 650mm, different cutting
Angle, various sizes of product will lead to different degrees of corner, and the rate reduction of material is not easy control, it is inclined to be easy to appear utilization rate
Low phenomenon.Fig. 1-2 shows that the length for working as finished product is 100mm, when width is 50mm, stock utilization 87.91%；Fig. 3-4
It shows, when the length of finished product is 124mm, and width is 69mm, stock utilization 94.02%.The prior art cuts wide cut
It is of single specification, cause material that cannot be utilized by reasonable maximization.
Summary of the invention
For overcome the deficiencies in the prior art, the purpose of the present invention is to provide a kind of promotion polarizer material utilization rates

Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the present invention, it should be noted that not
Under the premise of conflicting, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example.
A kind of cutting method promoting polarizer material utilization rate, comprising:
Simulate composition step: according to the absorption axiss angle of the length of default finished product, width and polaroid raw material, In
Simulation typesetting is carried out on CAD, and is reserved edging surplus and (provided a part of machining allowance, material cuts into small pieces, can carry out again
Processing edging) and tape-stripping edge amount (first polarizer material be pasted above backing plate using adhesive tape, then be cut out
It cuts)；
It determines wide cut step: according to the length of finished product, the length of width, polaroid raw material, and cutting wide cut, calculate
Stock utilization out, wherein cut wide cut=(length/width of monolithic finished product+edging surplus) * quantity+tape-stripping edge
Amount；
Cutting step: according to wide cut is cut, polaroid raw material is put into guillotine and are cut.
" quantity " being related in wide cut calculation formula is cut, how much cuts on wide cut direction available product for material
The number of column (this columns is integer).
Tape-stripping edge amount: it when confirming the wide cut of material, needs to increase the material of 4mm at edge, is used for Continuous pressing device for stereo-pattern.
Increase the tape-stripping amount of 4mm at the edge of each edge.After cutting to material, the tape-stripping amount of this 4mm is just thrown away
, belong to the normal loss of material.
Generally, edging surplus is configured in the following way: for product at 0 to 2.5 cun, edging surplus is 0, product
It is 1mm in 2.5 to 10 cun of edging surpluses, 10 cun to 15 cun edging surpluses of product are 1.5mm, and product is at 15 cun or more, more than edging
Amount is 2mm.
It, can voluntarily manual calculations when calculating stock utilization.Can also according to parameter that stock utilization is related to and
Operation relation designs a comptograph, in use, opening calculator, relevant parameter is inputted and carries out operation.See figure
2,4,7,9,11 and 13, operation, certainly, comptograph and voluntarily manual calculations obtain are carried out using comptograph
Result be consistent.But in actual production, about eight or nine ten coiled strips want planned production daily for intra-company, and
The wide cut of angle, length and width and preceding process supplied materials is different.If manual calculations are input in automatic software for calculation one by one manually
Accurate wide cut is obtained, will be very big workload.Therefore, the calculating of every kind of angle can be established in Excel table
Formula substitutes into length and width and is calculated.The calculation formula for cutting utilization rate is as described below:
The width/length of raw material/for cutting the long * product of the grain number * product for utilization rate=cut cuts wide cut
Either cut by which kind of mode at present and required certain machining allowance, error, error controlled range it
It is interior, the wide cut of material is controlled, guarantees the neither too much nor too little effect just of material.The present invention is in practical operation, according to product
The absorption axiss angle of length and width and material, on CAD carry out material simulation cut, guarantee can cutting with entire row permutation, will not
As there is the remaining situation cut in Fig. 5.Again there are machining allowance, guarantee that the utilization rate of material reaches maximum.
In addition, the length and width according to different product, because finished product has absorption axiss angle, so being needed during cutting
Different angles is put to master slice to meet.It determines during putting, guarantees that the number of finished product reaches maximum, as far as possible
Reduce the waste of material.
As further embodiment, in simulation composition step, polaroid raw material are polaroid coiled strip or polarisation
Piece master slice.
