Abstract
The invention discloses a screen printing plate processing method. A screen can be utilized to cover a screen printing plate surface, so that dust is prevented from blocking mesh holes in the screen printing plate. When the screen printing plate needs to be used, only the screen needs to be removed. According to the screen printing plate processing method, the dust is prevented from blocking the mesh holes, so that the phenomena of poor printing conditions such as gate breakage during electrode printing can be avoided. The qualification rate of the appearances of battery pieces can be improved.
Description
Technical field
The present invention relates to half tone processing technology field, particularly relate to a kind of half tone processing method.
Background technology
Solar cell, also claims photovoltaic cell, is the semiconductor devices that a kind of luminous energy by the sun is converted into electric energy.Because it is Green Product, can not cause environmental pollution, and be renewable resource, so under current energy starved situation, solar cell is a kind of novel energy having broad based growth future.
In the production process of solar cell, need the technique of carrying out printing electrode, that is: print front side silver paste, back side aluminium paste and backplate, it makes slurry through the mesh in half tone with certain figure by printing machine, be printed onto on cell piece, to form required figure.
But applicant studies discovery, because the mesh diameter in half tone is very little, be therefore easy to by air decline into mesh dust block, and then cause the printing such as disconnected grid unfavorable condition when printing electrode, cell piece appearance yield declined.
Summary of the invention
For solving the problems of the technologies described above, the embodiment of the present invention provides a kind of half tone processing method, and to solve the problem that in half tone, mesh is blocked by dust, technical scheme is as follows:
A kind of half tone processing method, comprising:
At half tone surface coverage one deck shelter, enter mesh in described half tone to prevent dust;
Before the described half tone of use carries out serigraphy, remove described shelter.
Preferably, described shelter is viscosity organic liquid.
Preferably, the method removing described shelter is specially: use the spirituous non-dust cloth of absorption to wipe described viscosity organic liquid.
Preferably, described viscosity organic liquid is terpinol.
Preferably, also comprise: use the described half tone removing described shelter to carry out serigraphy process.
By applying above technical scheme, a kind of half tone processing method provided by the invention, can use shelter to cover half tone surface, thus avoids the mesh in ash blocking half tone.When needs use half tone, remove this shelter to needs.The present invention is owing to avoiding dust blocking mesh, and therefore can avoid causing the printing unfavorable conditions such as disconnected grid when printing electrode, the present invention can improve the qualification rate of cell piece outward appearance.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, the accompanying drawing that the following describes is only some embodiments recorded in the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The process chart of a kind of half tone processing method that Fig. 1 provides for the embodiment of the present invention;
The process chart of the another kind of half tone processing method that Fig. 2 provides for the embodiment of the present invention.
Detailed description of the invention
Technical scheme in the present invention is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, should belong to the scope of protection of the invention.
As shown in Figure 1, a kind of half tone processing method that the embodiment of the present invention provides, can comprise:
S101, at half tone surface coverage one deck shelter, enter mesh in half tone to prevent dust;
Wherein, shelter can be viscosity organic liquid.Certainly, shelter can also be other article in other embodiments of the present invention, as glassine paper, plastic sheeting etc.Preferably, viscosity organic liquid is terpinol.Terpinol is colourless thick liquid at normal temperatures, its relative density 0.9337 DEG C.General industry product are the mixture of three kinds of isomers: alpha-terpineol has left-handed, dextrorotation, racemization three kinds of optical isomers.Terpinol is water insoluble, is dissolved in the organic solvents such as ethanol.1 part of terpinol can be dissolved in the ethanolic solution of 2 parts of (volumes) 70%.Terpinol is easy to be dissolved in organic solvent, is therefore easy to remove.
It is easily understood that after using shelter to cover half tone surface, dust just can drop on shelter, thus no longer falls into the mesh of half tone, also would not cause the blocking of mesh in half tone.
S102, before half tone carries out serigraphy in use, remove shelter.
Wherein, when shelter is viscosity organic liquid, the method removing shelter can be specially: use absorption spirituous non-dust cloth erasing viscosity organic liquid.Be understandable that, viscosity organic liquid can be dissolved in alcohol, thus is wiped by non-dust cloth.Why adopting non-dust cloth to wipe, is because non-dust cloth can not bring new dust.
A kind of half tone processing method that the embodiment of the present invention provides, can use shelter to cover half tone surface, thus avoids the mesh in ash blocking half tone.When needs use half tone, remove this shelter to needs.The present invention is owing to avoiding dust blocking mesh, and therefore can avoid causing the printing unfavorable conditions such as disconnected grid when printing electrode, the present invention can improve the qualification rate of cell piece outward appearance.
As shown in Figure 2, in the another kind of half tone processing method that the embodiment of the present invention provides, can also comprise:
The half tone of S103, use removal shelter carries out serigraphy process.
Wherein, step S103 can specifically comprise: at cell panel front printing silver slurry with in panel backside printing aluminium paste and backplate.
Each embodiment in this description all adopts the mode of going forward one by one to describe, between each embodiment identical similar part mutually see, what each embodiment stressed is the difference with other embodiments.
The above is only the specific embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
