Abstract

The invention relates to a method used for overlapped positioning and transition processing of digital ink jet printer spray head splicing. Errors are avoided by using the flexibility and the alterability of digital control and an end-to-end overlapping method. N overlapped dot pitches are preset and trial printing is performed on a drawing in advance so that an overlapping relation of dots is predicted. According to the number of overlapped dots, the overlapped parts of the head and the tail of the spray heads a and b are printed with part of ink dots, so the relation of mackle is eliminated, and intervals among at least n dot ditches can be regulated so that all kinds of errors are corrected.

Description

The overlapping position error processing method of splicing spray
Technical field
The present invention relates to a kind of overlapping location of Numerical Control Printer shower nozzle splicing and method of transition processing of being used for.
Background technology
In extensive output Numerical Control Printer, the method that often adopts shower nozzle to splice from beginning to end solves the little problem of single shower nozzle air brushing scope.But the head and the tail connection of shower nozzle is subjected to repeatedly affect positioning of machine-building machining accuracy and repeated disassembled and assembled, and the error that makes two shower nozzles splice from beginning to end is very big.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of method simple, use the overlapping location that is used for the splicing of Numerical Control Printer shower nozzle that is used to compensate the error that two shower nozzles splicings cause accurately and reliably and the method for transition processing.
In order to solve above technical problem, the present invention has adopted end to end method of superposition, designs overlapping n some distance in advance, tries the spray printing master drawing in advance, knows its overlapping relation; According to overlapping what, make each spray printing part ink dot of repeating part of shower nozzle a, b head and the tail, eliminating the relation of mcakle, and guarantee to put apart from adjustable distance to revise various errors for n at least.
Method step of the present invention is:
Step 1, splicing spray, the afterbody specking of establishing shower nozzle a is a1, a2, a3, a4 The stem specking of shower nozzle b is b1, b2, b3, b4 ..., splice it overlapping from beginning to end;
The lap Xn of step 2, a default overlapping n specking 0, the spray printing master drawing;
Wherein: Xn 0Original value for n the lap of putting;
N the overlapping value of specking Xn of step 3, actual measurement master drawing m, Xn mFor n the point in the overlapping value of m time actual measurement;
Step 4, calculating Xn m/ Xn 0Value;
Step 5, computing formula:
a1=b1,a2=b2
a3=b3,a4=b4
The single specking total amount of a1+b4=a2+b3=a3+b2=a4+b1=
Step 6, according to measured value, compensate each specking value, a1 * Xn m/ Xn 0, a2 * Xn m/ Xn 0, a3 * Xn m/ Xn 0, a4 * Xn m/ Xn 0And b1 * Xn m/ Xn 01, b2 * Xn m/ Xn 0, b3 * Xn m/ Xn 0, b4 * Xn m/ Xn 0
Step 7, formal spray printing.
Advantage of the present invention is, can compensate the various errors that cause two shower nozzles splicings to cause because of various factors, and method simply and accurately and reliably.
Description of drawings
Fig. 1 is two schematic diagrames that shower nozzle splices from beginning to end;
Fig. 2 (Fig. 2 A, Fig. 2 B and Fig. 2 C) is different overlapping relation schematic diagrames;
Fig. 3 is a flow chart of the present invention.
The specific embodiment
See also shown in the accompanying drawing, the invention will be further described.
As shown in figures 1 and 3, in the location of design splicing spray, the lap Xn of default n point 0, Xn 0Original value for n the lap of putting tries the spray printing master drawing then in advance, can predict its overlapping relation by measuring, i.e. Xn mValue, Xn mBe the mean value of n point m time the overlapping value of actual measurement.According to overlapping Xn mValue makes a, b shower nozzle each spray printing n ink dot of repeating part from beginning to end, and with the relation of elimination mcakle, and assurance has at least n to put apart from adjustable distance with round-off error.
Below with overlapping 4 be embodiment, specify the present invention.
Sprout wings to handle: it is corresponding fully to establish a1-a4 and b1-b4, carries out from shallow to deep emergence transition processing respectively from a1-a4 and b1-b4 in Fig. 2 A.Be in theory:
The total amount of the former specking of a1+b4=a2+b3=a3+b2=a4+b1=
If the error of a point has taken place, shown in Fig. 2 B:
Then: the total amount of the former specking of a4=a3+b1=a2+b2=a1+b3=b4=
If the error of a point has taken place to be less than, shown in Fig. 2 C, then available: total amount compensation process is sprouted wings.Sprout wings and refer to the ratio of specking spray volume when shower nozzle is laterally worked.
Embodiment 1: the depth is sprouted wings and is handled: (shown in Fig. 2 A), and then can establish:
Actual measurement draws X4 1=X4 0
a1=20%,b1=20%;
a2=40%,b2=40%;
a3=60%,b3=60%;
a4=80%,b4=80%;
A1+b4=100% then;
a2+b3=100%;
a3+b2=100%;
a4+b1=100%。
Just can realize that shower nozzle a, b handle in the emergence of overlapping, make final effect consistent with underlapped part effect.This emergence effect can also separate effectively that part specking in the eclosion process is not by no means worked for a long time and the specking service behaviour that causes changes or stop up.
The emergence percent value can define arbitrarily or produce at random, but need satisfy the consistent requirement of total amount.
Embodiment 2 (shown in Fig. 2 C): total amount penalty method.
Actual measurement draws X4 3>X4 0,
Then total amount should increase: X4 3/ X4 0, then a1-a4 and b1-b4 all should increase X4 3/ X4 0Amount.
As: X4 3/ X4 0=112.5%,
Suppose a1 and b1 phase difference of half point
A1=20%*1.125=22.5% then;
a2=40%*1.125=45%;
a3=60%*1.125=67.5%;
a4=80%*1.125=90%;
Then b1-b4 is also similar, and last total specking amount in the X3 zone is consistent with non-this regional specking effect.
Embodiment 3 (as Fig. 2 B):
Actual measurement draws a point of complete dislocation distance, then
X4 2/X4 0=125%;
A1=20%*1.25=25% then;
a2=40%*1.25=50%;
a3=60%*1.25=75%;
a4=80%*1.25=100%;
Then b1-b4 is also similar, and the effect in the last X2 zone is consistent with non-this regional specking effect.Also consistent with the result shown in Fig. 2 A.
