Description
Technical field
The present invention relates to a kind of direct electrostatic printing technique, particularly a kind of control method of electrode assembly of direct electrostatic printing equipment and structure thereof.
Background technology
When printing, or when duplicating digitized image, corresponding to original or the image that is intended to print, can on a surface, form stealthy electrostatic charge point, and form pattern by these points with height resolution from computer.
In continuous printing step, have the surface of electrostatic image pattern, generally can as toner, form image by the charged particle that closes on.By between imaging point, causing enough electric fields, order about charged particle and can jump out from cartridge device, be attached to the surface that receives body, form required pattern.
In various static dump technology, the most common and generally use xerox (xerography) or be called photoelectricity replica technology (electrophotography) as xerox.The pattern that desire is printed is by laser or other light sources device, form with light is transferred on the optics reception body, and cause the potential difference (PD) that receives on the body, form the electrostatic image pattern, then develop, image is appeared by charged toner material, then shift image to paper, because image is to be formed on an intermediate optical earlier to receive body, and then is transferred on the paper surface, so this process is called non-direct print procedure.

At first as Fig. 1, it represents the structural representation of direct electrostatic printing equipment of the present invention.Direct electrostatic printing equipment (DEP) as traditional includes a cartridge device 10 at least, such as the feeding mechanism that is roller type, is used to provide charged toner particle, such as being carbon dust 12, or other colored particle, as pigment or dyestuff; One electrode assembly 20, it has a plurality of holes 22, runs through this electrode assembly 20; One recording medium 30 such as being paper, is used for writing down the image that institute's desire shows; And an electrode assembly 40 dorsad, can cooperate with electrode assembly, be used for attracting carbon dust 12 to make it attached on the recording medium 30.The carbon dust 12 that is provided by cartridge device 10 has electric charge, such as negative charge, add and apply on the electrode assembly 20 and the opposite voltage of carbon dust institute charging property, such as positive voltage, carbon dust 12 is subjected to electrode assembly 20 formed electric field attracts, pass the hole 22 on the electrode assembly 20, being subjected to subsequently is the electric field attracts that applies with the electrode assembly dorsad 40 of carbon dust institute charging property opposite voltage equally, and is adsorbed on the recording medium 30.
Also having a kind of type of drive in addition, is to apply on electrode assembly 20 and the identical voltage of carbon dust institute charging property, such as negative voltage, and electrode assembly 40 is to apply and the opposite voltage of carbon dust institute charging property dorsad, such as positive voltage, and its voltage swing is big far beyond the voltage of electrode assembly.Because the additive property of electric field after the less negative electric field addition that positive electric field and electrode assembly are produced greatly that electrode assembly 40 is produced, still is a positive electric field dorsad, thus still can attract carbon dust, and on the recording medium 30 that arrives.
First embodiment please be simultaneously with reference to Fig. 2 a and 2b, and it represents the side cutaway view and the hierarchy synoptic diagram of electrode assembly of the present invention respectively.Electrode assembly 20 of the present invention is made up of n layer electrode layer, the number of plies of electrode layer must be decided on stratum's number of printing, such as being about the 2-100 layer, but not as limit, in order to make the person of readding can know understanding the present invention, the present invention will be that example describes with 4 electrode layers.Electrode assembly 20 is made up of electrode layer 202,204,206 and 208, has at least one hole 22 on the electrode assembly 20, runs through these electrode layers 202,204,206 and 208.The tens of approximately microns of the diameter of hole 22, if the resolution of printing is not high, diameter is about hundreds of microns, shape can be circular, square or other shapes.If with linear print, 22 of holes form a line.If array is printed, the arrangement of hole 22 then can reach ordered series of numbers, such as being 4 row, shown in Fig. 2 b.
Electrode layer 202,204,206 and 208 is made of insulating material and conducting wire, and each layer electrode layer is that basic unit forms insulation course with the insulating material, and on insulation course required conducting wire, the hole 22 on the surrounding electric poles layer.The present invention does not limit the layout of conducting wire, if can make the conducting wire around hole 22 or part around hole 22, and apply voltage and get final product.The present invention will be that example describes with the twin shaft circuit.
Shown in Fig. 2 b, each layer electrode layer all has the standard shaft electrode 212,214,216 and 218 that is arranged in parallel, and Control Shaft electrode 222,224,226 and 228.Standard shaft electrode 212,214,216 and 218 is connected to the standard shaft circuit via lead respectively, and Control Shaft electrode 222,224,226 and 228 also is connected to the Control Shaft circuit via lead respectively.Whether determine at standard shaft electrode 212,214,216 and 218 by standard shaft circuit and Control Shaft circuit, with apply voltage on Control Shaft electrode 222,224,226 and 228, standard shaft electrode and Control Shaft electrode intersect at hole 22, and diaxon can be vertical mutually, or with other angle of intersection.For example, standard shaft electrode 212 intersects at hole H with Control Shaft electrode 222
11(22), and by the standard shaft electrode 212 of electrode layer 202 whether control at this hole H with Control Shaft electrode 222
11Apply electric field.By each layer electrode layer 202,204,206 and 208 whether at hole H
11Apply voltage, decision is at hole H
11Total phase making alive, and can determine the size of the electric field that applied.The available voltage swing of each electrode layer is all equal in the present embodiment.For example, each layer electrode layer 202,204,206 and 208 all drags the voltage that adds 50V, and then total phase making alive is 200V.In addition, can on these electrode layers, add one deck basal electrode layer (not shown) again, adjust the initial voltage of electrode assembly with this.For example, the voltage that the basal electrode layer is applied is 200V, and cooperates the voltage of other this 4 layers of electrode layer, and then voltage range is 200-400V.In addition, also can remove the basal electrode layer, the voltage of directly adjusting ground floor is 250V, cooperates other 3 layers of electrode layers again, and then voltage range also is 250～400V.
If electrode assembly 20 has n layer electrode layer, each layer electrode layer all can determine whether to apply a voltage to hole H
11, then be applied to hole H
11Voltage can be divided into (n 10) individual stratum, promptly 0 stratum is to n stratum.So can be at hole H
11Form the electric field of (n+1) individual stratum, can form the printing degree of depth of (n+1) individual stratum with this.When needs are printed m stratum when printing the degree of depth (its print range from 0 stratum to n stratum), for hole H
11, on the electrode layer that is total to the m layer, apply voltage together, form the electric field of m stratum, form the printing degree of depth of m stratum with this.
With 4 layers of electrode layer is example, at hole H
11The voltage that applies can be divided into 5 stratum (0～4 stratum).When the no-voltage added-time, hole H
11Not having carbon dust 12 and pass through, is 0 stratum so print the degree of depth, so print point is blank.When applying voltage on 1 layer of electrode layer therein, a spot of carbon dust is arranged by hole H
11And form the printing degree of depth of the 1st stratum, when wherein 2 layers of electrode layer applied voltage, then degree of printing was the 2nd stratum.Similarly, can also be applied to the 3rd stratum and the 4th stratum, as shown in Figure 3, it represents electrode assembly of the present invention, uses 4 layers of electrode layer, to the printing degree of depth that single hole printed.Its concentration ratio distributes, and such as being 0%, 25%, 50%, 75%, 100%, when the electrode assembly 20 employed numbers of plies more height, stratum's number of the printing degree of depth that relatively is divided into is also just high.

Then will further specify the control method of electrode assembly of the present invention.Please be simultaneously with reference to Fig. 1, and 2a schemes with 2b, cartridge device 10 provides charged toner particle, such as being carbon dust 12.In the time of near electronegative carbon dust 12 arrives electrode assembly 20, be subjected to having applied in the electrode assembly 20 the formed electric field attracts of electrode layer of voltage, and pass hole 22, the carbon dust amount of passing hole 22 is directly proportional with the size of voltage, with the twin shaft electrode is example, in n layer electrode layer, and be at hole H
11, when printing the printing degree of depth of m stratum, apply voltage, and apply voltage together on the electrode layer of m layer altogether, then at hole H at Control Shaft at the standard shaft electrode 212 of each layer electrode layer
11Required electric field when total m layer electrode layer conducting forms the printing degree of depth of printing m stratum, the carbon dust amount that attracts m stratum to print the degree of depth is passed hole H
11Pass hole H
11Carbon dust 12, be subjected to the formed electric field attracts of high voltage of electrode assembly 40 dorsad and be attached on the recording medium 30.Generally speaking, cartridge device 10 and dorsad the voltage difference between the electrode assembly 40 about 1000-2500V.If use the structure shown in Fig. 5 a and the 5b, or during similar structures,, get final product so only need on the Control Shaft electrode of m layer electrode layer, to apply voltage together owing to there is not the standard shaft electrode.
When printing, can use the mode that layout prints, the phenomenon of avoiding two adjacent print point generation phase mutual interference.With the lateral separation is example.Hole H during printing
11With H
13Print simultaneously, can avoid hole H
11With H
13Hole H is then carried out in the phase mutual interference again
11With H

Then will narrate another preferred embodiment of the present invention.Structure at this employed electrode assembly is identical with the structure of the employed electrode assembly of first embodiment, and not superpotential control method slightly is different from first embodiment.
As shown in figure 11, each layer electrode layer all has the standard shaft electrode 1212,1214,1216 and 1218 that is arranged in parallel, and Control Shaft electrode 1222,1224,1226 and 1228. Standard shaft electrode 1212,1214,1216 and 1218 is connected to the standard shaft circuit via lead respectively, and Control Shaft electrode 1222,1224,1226 and 1228 also is connected to the Control Shaft circuit via lead respectively.By the decision of standard shaft circuit and Control Shaft circuit whether standard shaft electrode 1212,1214,1216 and 1218 and Control Shaft electrode 1222,1224,1226 and 1228 on apply voltage.Standard shaft electrode and Control Shaft electrode intersect at hole 22, and diaxon can be vertical mutually, or with other angle of intersection.Whether standard shaft electrode and the control of Control Shaft electrode by electrode layer apply electric field at 22 of hole.Whether apply voltage by each layer electrode layer 1202,1204 and 1206, then can determine total phase making alive at hole 22 at hole 22, and the size of the electric field that decision is applied.As described in first embodiment, also can use other wire laying mode as for the conducting wire.
In this embodiment, each layer electrode layer 1202,1204 and 1206 voltages that applied are all inequality, and it presents twice and increases progressively.For example, apply voltage 1aV on the electrode layer 1202, then apply voltage 2aV on the electrode layer 1204, and apply voltage 4aV on the electrode layer 1206, and increase progressively according to this, during to n layer electrode layer, the voltage that is applied then is 2
N-1AV.Apply 20V such as electrode layer 1202, electrode layer 1204 applies 40V, and electrode layer 1206 applies 80V, increases progressively according to this, so form voltage the combination of 2 carries.By controlling the Push And Release of each layer electrode layer, can form the logical combination of 2 carries of voltage.
If electrode assembly 20 has n layer electrode layer, be generally 2 layers to 15 layers, but not as limit, each layer electrode layer all can determine whether to apply a voltage to hole 22, the voltage that then is applied to hole 22 can be divided into 2
n(2 n powers) individual stratum, promptly 0 stratum is to (2
n-1) stratum.So can form 2 at hole 22
nThe electric field of individual stratum can form 2 with this
nThe printing degree of depth of individual stratum.When needs print m stratum when printing the degree of depth (its print range from 0 stratum to (2
n-1), on m layer electrode layer, applies one 2 carry combination voltages stratum), form the electric field of m stratum, order about carbon dust 12 and pass hole 22 and be attached on the recording medium, thereby form the printing degree of depth of m stratum.
This one 2 carry combination voltage is the logical combination for 2 carries.With 3 layers of electrode layer is example, and the voltage that applies at hole 22 can be divided into 8 stratum (0～7 stratum).When no-voltage applied, hole 22 does not have carbon dust 12 to be passed through, and was 0 stratum so print the degree of depth, and this print point is blank.Apply voltage 1aV on electrode layer 1202, and the voltage of electrode layer 1204 and 1206 is when being 0V, total phase making alive is 1aV, forms the printing degree of depth of the 1st stratum.When electrode layer 1204 applies voltage 2aV, and electrode layer 1202 and 1206 is when being 0V, and total phase making alive is 2aV, forms the printing degree of depth of the 2nd stratum.When electrode layer 1202 and 1204 applies voltage 1aV and 2aV respectively, and electrode layer 1206 is when being 0V, and total phase making alive is 3aV, forms the printing degree of depth of the 3rd stratum.The rest may be inferred, similarly can be applied to the 4th, 5,6 stratum.When electrode layer 1202,1204 and 1206 applied voltage 1aV, 2aV and 4aV respectively, total phase making alive was 7aV, and forms the printing degree of depth of the 7th stratum.
But the order that voltage increases progressively might not be relevant with the order of electrode layer, such as applying 2aV on the electrode layer 1202, applies 4aV on the electrode layer 1204, applies 1aV on the electrode layer 1206.But be on electrode layer 1202,1204,1206, to apply 1aV, 2aV and 4aV is an example in the present embodiment.
By the switch of control electrode layer 1202,1204 and 1206, can be combined into the logical combination of 2 carries of voltage.So can mark off the printing degree of depth of 8 stratum.Its concentration ratio is distributed, such as can being 0%, 14.3%, 28.6%, 42.9%, 57.2%, 71.5%, 85.8%, 100%.When the electrode assembly 20 employed numbers of plies more height, stratum's number of the printing degree of depth that relatively is divided into is also just high, but the restriction of necessary control voltage.
Described in first embodiment, pass 22 carbon dust 12 of hole, be subjected to the formed electric field attracts of high voltage of electrode assembly 40 dorsad and be attached on the recording medium 30.Generally speaking, cartridge device 10 and dorsad the voltage difference between the electrode assembly 40 about 1000-2500V.
The control method of electrode assembly of the present invention can also be applied in other forms of direct electrostatic printing equipment.For example, carbon dust 12 is adsorbed on earlier on the intermediate transfer body, and then carbon dust 12 is transferred on the recording medium 30, as for the manufacture method of electrode assembly, as the described various manufacture methods of first embodiment, all is included among this embodiment.
Then narrate another preferred embodiment of the present invention again.Structure at this employed electrode assembly is identical with the structure of the employed electrode assembly of first embodiment, and not superpotential control method slightly is different from first and second embodiment.
As shown in figure 12, each layer electrode layer all has the standard shaft electrode 2212,2214,2216 and 2218 that is arranged in parallel, and the Control Shaft electrode 2222,2224,2226 and 2228.Standard shaft electrode 2212,2214,2216 and 2218 is connected to the standard shaft circuit via lead respectively, and Control Shaft electrode 2222,2224,2226 and 2228 also is connected to the Control Shaft circuit via lead respectively.By the decision of standard shaft circuit and Control Shaft circuit whether standard shaft electrode 2212,2214,2216 and 2218 and Control Shaft electrode 2222,2224,2226 and 2228 on apply voltage.Standard shaft electrode and Control Shaft electrode intersect at hole 22, and diaxon can be vertical mutually, or with other angle of intersection.Whether standard shaft electrode and the control of Control Shaft electrode by electrode layer apply electric field at hole 22.Whether apply voltage by each layer electrode layer 2202,2204 and 2206, then can determine total phase making alive at hole 22 at hole 22, and the size of the electric field that decision is applied.As described in first embodiment, also can use other wire laying mode as for the conducting wire.
In this embodiment, each layer electrode layer 2202,2204 and 2206 voltages that applied are all inequality, and it presents equal difference and increases progressively.For example, apply voltage 1aV on the electrode layer 2202, then apply voltage 2aV on the electrode layer 2204, and apply voltage 3aV on the electrode layer 2206, and increase progressively according to this, during to n layer electrode layer, the voltage that is applied then is (n*aV).Apply 50V such as electrode layer 2202, electrode layer 2204 applies 100V, and electrode layer 2206 applies 150V, increases progressively according to this, so forms the curtain time combination of voltage.By controlling the switch of each layer electrode layer, can form the curtain time combination of voltage.
If electrode assembly 20 has n layer electrode layer, be generally 2 layers to 50 layers, but not as limit, each layer electrode layer all can determine whether to apply a voltage to hole 22, the printing degree of depth (∑ n) that the voltage that then is applied to hole 22 can be divided into (∑ n+1) individual stratum is the arithmetic series summation for n, for example work as n=4, ∑ n=4+3+2+1=10), promptly 0 stratum is to (∑ n) stratum.So can form the electric field of (∑ n+1) individual stratum at hole 22, can form the printing degree of depth of (∑ n+1) individual stratum with this.When needs are printed m stratum when printing the degree of depth (its print range from 0 stratum to (∑ n) stratum), on m layer electrode layer, apply combination voltage one act time, form the electric field of m stratum, order about carbon dust 12 and pass hole 22 and be attached on the recording medium, thereby form the printing degree of depth of m stratum.
This act combination voltage is to collect combination for inferior sieve of equal difference curtain, is example with 3 layers of electrode layer, and the voltage that applies at hole 22 can be divided into 7 stratum (0-6 stratum).When no-voltage applies, hole 22 does not have carbon dust 12 to be passed through, so printing the degree of depth is 0 stratum, this print point is blank, on electrode layer 2202, apply voltage 1aV, and when the voltage of electrode layer 2204 and 2206 was 0V, total phase making alive was 1aV, forms the printing degree of depth of the 1st stratum, when electrode layer 2204 applies voltage 2aV, and when electrode layer 2202 and 2206 was 0V, total phase making alive was 2aV, forms the printing degree of depth of the 2nd stratum, when electrode layer 2206 applies voltage 3aV, and when electrode layer 2202 and 2204 was respectively 0V, total phase making alive was 3aV, forms the printing degree of depth of three-layered.When electrode layer 2202 and 2206 applies voltage 1aV and 3aV respectively, and electrode layer 2204 is when being 0V, and total phase making alive is 4aV, forms the printing degree of depth of the 4th stratum.The rest may be inferred, similarly can be applied to the 5th stratum, when 2202,2204 and 2206 of electrode layer applies voltage 1aV, 2aV and 3aV respectively, total phase making alive is 6aV, and form the printing degree of depth of the 6th stratum, wherein, total phase making alive 3aV also can apply voltage 1aV and 2aV and forms 2202 and 2204.
By the switch of control electrode layer 2202,2204 and 2206, can be combined into the curtain time combination of voltage.So can mark off the printing degree of depth of 7 stratum.Its concentration ratio is distributed, such as can being 0%, 16.7%, 33%, 50%, 66.7%, 83%, 100%.When the electrode assembly 20 employed numbers of plies more height, stratum's number of the printing degree of depth that relatively is divided into is also just high, but the restriction of necessary control voltage.

The control method of electrode assembly of the present invention can also be applied in other forms of direct electrostatic printing equipment.For example, carbon dust 12 is adsorbed on earlier on the intermediate transfer body, and then carbon dust 12 is transferred on the recording medium 30, as for the manufacture method of electrode assembly, fails the various manufacture methods of stating as first embodiment, all is included among this embodiment.
Referring again to Figure 12, this also is an another embodiment of the present invention, be same as precedent but each layer electrode layer 2202,2204 is all different with 2206 voltages that applied in this employed electrode assembly structure, for example, on electrode layer 2202, apply-100V, apply on the electrode layer 2204-200V, and on electrode layer 2206, apply 400V, so in this voltage design, can show 0V, 100V, 200V, 300V and 400V altogether, can mark off the printing degree of depth of 5 stratum, concentration ratio be assigned as 0%, 25%, 50%, 75% and 100%.Meriting attention is that two layers of electrode layer are arranged in this example is to apply identical electrical voltage with charged particle, only has only with the electrode layer of the identical voltage of charged particle and does the time spent, and the comparable voltage that do not apply more can effectively block charged particle and passes through.
Described in first embodiment, pass the carbon dust 12 of hole 22, be subjected to the formed electric field attracts of high voltage of electrode assembly 40 dorsad and be attached on the recording medium 30.Generally speaking, cartridge device 10 and dorsad the voltage difference between the electrode assembly 40 about 1000-2500V.
The control method of electrode assembly of the present invention can also be applied in other forms of direct electrostatic printing equipment.For example, carbon dust 12 is adsorbed on earlier on the intermediate transfer body, and then carbon dust 12 is transferred on the recording medium 30.As for the manufacture method of electrode assembly,, all be included among this embodiment as the described various manufacture methods of first embodiment.
