In this printer, outbalance be to shine the light that all when copying, has equal number of having a few of printing forme; And this light collimation, the vertical incidence so that the light on the solarization printing forme can be tried one's best is shone on the printing forme to guarantee that the forme crystal structure can be transferred to light exactly.
Background technology
For reaching described purpose, some the popular machine be familiar with described in US Patent No. 2009/0244510 application has used the strut type mobile support saddle, so that can be moved in the zone relative with shining printing forme; Need some led light sources be installed along the crystal structure position that calculates, so that the bearing during copying moves and can drive each point that shines printing forme and obtain uniform copying effect, and make each point that shines printing forme all obtain the uniform light of equal number.
But in these machines that adopt prior art to produce, LED pole is very narrow: pole need be run very long stroke just can go around all positions of shining printing forme.This just causes occurring a bigger defective, that is: the operating cycle long, and the pole stroke that should the run length that should equal to shine printing forme at least.The defective in this defective and copying stage is the same outstanding, namely can be restricted aspect kinematics in the P.e.c. manufacture process.
Summary of the invention
The present invention then can address this problem.
More particularly, the present invention relates to a kind of used for printed circuit printer, its composition comprises at least: a light-emitting diodes pipe support is arranged on the parallel plane corresponding with the copying board support copying board support one side and Y-axis conllinear along X-axis and Y-axis orthogonal directions; Be used for to guarantee that the diode bearing carries out the equipment that relatively moves with respect to the copying board support in Y-axis; Some light emitting diodes (LED), instantaneous the lighting or instantaneous extinguishing of energy is installed on the described light-emitting diodes pipe support, along the direction regular distribution of extending in X-axis, the light beam that each diode sends all along with the Z axis of X-axis and Y-axis quadrature, light beam is towards shining printing forme; Described copying board support is used for supporting the forme corresponding with described solarization printing forme, between described solarization printing forme and diode bearing; It is characterized in that, the light emitting diode installation region on the diode bearing, its size strictness is greater than the size of shining printing forme on X-axis and the Y-axis both direction; Diode is even at interval on Y-axis, and observes the dislocation value requirement between two row on the X-axis; And be that relatively moving between diode bearing and the solarization printing forme is the stroke that produces along Y-axis; The trip can comprise:
-accelerate dead stroke; Reach specified solarization print-out rate, light emitting diode extinguishes in this trip;
-effective copying stroke, namely distance is less than the size of copying on the Y-axis; At this moment, lumination of light emitting diode reaches constant speed; The diode installation region can cover this solarization printing forme fully at whole stroke; And
-dead stroke slows down; This moment, light emitting diode extinguished, and slowing down, it is mobile to stop.
Under this kind configuration condition, can calculate the above-listed dislocation value of X-axis, so that the light that each point is received on the circuit board in the whole time limit at led lighting when effective copying stroke takes place all is uniformities.In addition, because reason that should dislocation, need the size of diode installation region to be slightly larger than the size of installation region on the X-axis, so that the antivacuum homogeneous diode that shines on the printing forme can be distributed on each edge according to this.The size that also needs simultaneously the diode installation region is obviously greater than the size of installation region on the Y-axis, so that the present invention can be effective; And the diode installation region can hold the solarization printing forme fully in the process that produces the copying process.At last, be conducive to when diode extinguishes to produce and slow down and accelerate dead stroke, preventing that the copying homogeneity that calculates when the effective travel from being upset, thereby make some diodes when producing dead stroke, appear at the position corresponding with shining printing forme at this point.
Have benefited from the present invention, it is very short that the trip becomes, widely less than the length of shining printing forme, be enough to guarantee fully and this solarization printing forme of copying equably: after the trip shortens, thereby can equate in addition more excellent quality and level of efficiency on shorten the manufacturing cycle significantly and play the effect that reduces cost.
Its advantage is that this printer also comprises some parallel light pipes; Every parallel light tube all links to each other with a light emitting diode, and is arranged in the place ahead of described diode, can be parallel and impinge perpendicularly on and shine on the printing forme to guarantee light that light source sends.
At first, be used for guaranteeing that the diode bearing carries out being applicable to the diode bearing with respect to the equipment that relatively moves of copying board support; Described copying board support is hold-down support.
Its advantage is that the diode bearing is divided into some identical poles (hereinafter referred is pole) in Y-axis; Each pole includes some in light emitting diode n row (n〉l) crystal structure and observing in the dislocation value requirement between two row on the X-axis at interval uniformly on the Y-axis; Interval on the pole between diode two row should with last row of pole and next pole first row between the interval equate guaranteeing that the diode distribution has continuity between different poles, and not have any interruption.
Simply, its advantage is on each pole, and whenever the listing of light emitting diode, and the spacing between two adjacent light emitting diodes on the X-axis is p; And the diode on specific certain row can be along the adjacent relatively light emitting diode dislocation that lists with delegation of X-axis, and its dislocation value is p/n.So just can diode be installed with single and continuous spacing, and can when producing valid process, reach desirable copying uniformity coefficient.
What at first need consider is that each pole comprises 20 light emitting diodes of five row.
Its advantage is that effectively copying length is about the pole size on the Y-axis.
According to favourable and top-priority embodiment, every parallel light tube is formed by transparent integrated formula element, is apparent that its shape is generally the non-sphere of turning axle symmetry, and top flat is smooth and towards shining printing forme, the bottom is coaxial cavity; In this cavity, be placed with the light emitting diode that links to each other with parallel light tube; The end face of this cavity is relative with diode, and it is shaped as the axisymmetric non-spherical concave surface of rotation.This embodiment can guarantee that the angle of collimation that the half-angle centrum sends is about 2 °.

Embodiment
Fig. 1 is the printer 1 upright pseudosection of drawing according to the preferred embodiment for the present invention.
This printer 1 comprises supporting the copying board support 2 that shines printing forme 3 and is used for carrying out at this solarization printing forme forme 5 and the 5' of sensitization.In use, shine printing forme 3 and be placed on the copying board support 2 between two blocks of translucent glasses 4 and the 4': two formes 5 and 5' are installed in respectively and shine printing forme 2 two sides, back to the inside surface of two blocks of glass 4 and 4'.Can produce afterburning space between two blocks of glass, to guarantee to contact between different assembly elements well: because the cause of peripheral axle envelope 6 is arranged, can in the whole operation process, keep this space.
This printer 1 comprises light-emitting diodes pipe support 10 and 10' and the copying board support 2 that is respectively applied to guarantee to shine the printing forme copying equally.Allow diode bearing 10 and 10' to carry out with respect to the relatively moving of copying board support 2, so that copying equably.
Skeleton view among Fig. 2 can be observed the structure of diode bearing 10 or 10' better.
This diode bearing 10 is made up of some identical poles 11; Wherein in the present embodiment, will on Y-axis, arrange six such poles continuously.
On every pole, will the assembly of being made up of diode 20 and parallel light tube 30 be installed continuously according to the straight line that on X-axis, extends.Distance between last row of pole and next pole first row should equal the distance between two row in the same pole, and diode is distributed in two boundary lines between the pole.
Should keep certain intervals between two row on the X-axis: can guarantee that like this monoblock solarization printing forme 3 has uniform luminous flux after bearing 10 is moved.Therefore, need reserve the space of certain diode-less 20 at bearing 10 edges.For guaranteeing to have uniform luminous flux and the present invention's energy smooth implementation, in whole copying stroke, shining printing forme 3 at least should be in the rectangular extent that ABCD forms; Wherein BC limit and DA limit can be extended in X-axis, and first of bearing 10 is listed as and diode 20 centers of last row through being positioned at; Then extend in Y-axis respectively on AB limit and CD limit, and respectively through being positioned at the center of the most inboard diode in first row of every pole 11 and the zone of last row.We can say that the permutation diode extends to the diode pipeline in the horizontal.
In addition, diode bearing 10 also is equipped with the mobile device 13 such as trundle, track and engine, perhaps is equipped with to make diode bearing 10 carry out the equipment that relatively moves with respect to copying board support 2 in Y-axis.
Fig. 3 can understand the installation situation of diode 20 on every pole 11 in more detail.Therefore, can observe every pole 11 five row diodes 20 and parallel light tube 30 all are installed.These dislocation values that are listed on the X-axis each other equal p/n; Wherein p is same two spacings between the diode 20 that list, and n is a number of columns on the pole 11, and quantity is five herein.Calculate this dislocation value and can allow some identical poles 11 be distributed in monoblock according to continuous diode 20 on the one hand to shine on the printing forme, and between two poles 11 any interruption does not appear; Can guarantee on the other hand when the stroke that is equivalent to pole 11 length moves, can carry out copying at bearing 10 uniformly.
Whenever listing all has four little binding posts 12 on the pole 11 that is fixed on bearing 10, guarantees per five of the assembly that light emitting diode 20 and parallel light tube 30 are formed is fitted together.Therefore, whenever list and comprise 20 diodes 20, add up to 100 diodes 20 on every pole 11 like this.
These assemblies will be described in detail at Fig. 4 A and 4B.
Pay the utmost attention to the illuminating source of diode 20 in the ultraviolet spectral limit.
The end face 33 of cavity 32 faces diode 20, and it is shaped as the axisymmetric aspheric concave surface of rotation, therefore makes cavity 32 inside be convex.End face 33 can be coaxial with the axisymmetric non-sphere of rotation.
The shape of this end face 33 need be calculated so that the light that diode 20 produces can with the obvious conllinear of Z axle, and can penetrate object, refractive surface 33 and 31 is almost without any transitional zone.Otherwise the light of inclination can reflex to the side 34 of parallel light tube 30 by refractive surface 33; The parallel luminous energy of reflection shines printing forme 3 along returning with the direction of the obvious conllinear of Z axle.Therefore, the incident angle that this parallel light tube 30 can guarantee to shine on the printing forme 3 is reduced to 2 ° of the epicentral incident angles of half-angle, and light emitting diode incident angle during natural incident on the half-angle centrum then is about 60 °.
At last, Fig. 5 A to 5D has offered some clarification on the different phase of diode bearing 10 strokes when shining printing forme 3 and operate.
Fig. 5 A is the left end extreme position that allows stroke on the diode bearing 10.Bearing 10 is positioned at the start position that all diodes 20 are in the dead stroke of acceleration that extinguishes state at this moment.Because diode 20 has extinguished, so even some diode can be corresponding with solarization printing forme 3, also do not occur in and shine any the interference and inhomogeneous copying phenomenon of printing forme appearance acceleration.The trip is shorter relatively, and its length is less than the width of pole 11: the trip can arrive the given position of Fig. 5 B.
In this position, the right side extreme position of bearing 10 can arrive the right side extreme position that shines printing forme 3; Can arrive desirable copying rated speed this moment.Diode 20 is lighted by instantaneous: beginning copying effective travel.Under constant speed, in the length range of pole 11, carry out effective travel to guarantee to arrive desirable copying uniformity coefficient.Can determine this speed according to shining the copying energy consumption type that needs adopt on the printing forme, shine the required sensitivity of printing forme photoactive substance so that machine can reach: speed is crossed to hang down then can increase energy consumption; Excessive velocities then can cut down the consumption of energy.The monoblock that the installation region of diode 20 has been contained in whole copying stroke is shone printing forme 3.Leave fully when shining corresponding regional of printing forme 3 when first pole 11 of diode bearing 10, described installation region is not just in position shown in Fig. 5 C.
On this position, diode 20 will be because of the cause of the dead stroke that begun to slow down and is extinguished.Dead stroke is the same with accelerating, and need avoid occurring the inhomogeneous copying phenomenon of being disturbed; Although diode 20 is still corresponding with solarization printing forme 3.During whole retarding travel, bearing 10 will be limited action until being parked in position shown in Fig. 5 D fully.The trip needs to take place in very short distance, and this distance is less than the width of pole 11.
The position that provides among Fig. 5 D is the right side extreme position that diode bearing 10 allows in the stroke.
