Abstract
The invention relates to a novel glue scraping strip for silk-screen printing. The novel glue scraping strip comprises a main printing glue scraping strip and further comprises an auxiliary printing plate with an L-shaped cross section. The long edge of the auxiliary printing plate is connected with one side face of a glass fiber plate of the main printing glue scraping strip through a bolt or in a bonding manner, and a certain distance h is reserved between the short edge of the auxiliary printing plate and the bottom edge of the main printing glue scraping strip. The novel glue scraping strip has the effects that the production cost is low, two times of printing can be achieved through one printing head, the problem about alignment does not exist, and the production and use difficulty are reduced greatly.
Description
Technical field
The present invention relates to manufacture of solar cells manufacture field, specifically discloses a kind of new serigraphy frictioning bar.
Background technology
The progressively popularization generated electricity with crystal silicon solar and popularization, high performance solar batteries piece becomes the emphasis of each system business demand, therefore low-cost high-efficiency solar battery sheet is more becoming the direction that each factory is pursued.In existing high efficiency technical, much it is required for the equipment investment of costliness, such as PERC, the technologies such as RIE, HIT, although printing technology investment twice is little, but because it needs chromatography alignment, therefore the deformation of the alignment precision and half tone to equipment have very high requirement, while production management control require it is very high, it is difficult to popularize.
Original printing scraping article only one of which face within a print cycle has the effect of printing, after the minimal openings width of screen painting figure becomes narrow gradually or slurry viscosity increases, strike through amount during printing is very poor, even result in large area printing bad, grid line disconnects when serious, electric current collection ability declines, and finally have impact on the outward appearance and performance of cell piece.
The content of the invention
It is an object of the invention to：A kind of low production cost is provided to solve problem above, with a print head effect of secondary printing can be just reached, not there is a problem of alignment, greatly reduce the new serigraphy frictioning bar of production and application difficulty.
The technical solution adopted in the present invention is such：
A kind of new serigraphy frictioning bar, including main printing frictioning bar, also include the L-shaped auxiliary printed panel in a section, its longer sides is connected with face with the glass-fiber-plate one side of the main printing frictioning bar by bolt or bonding, and its shorter edge has certain distance h with the main printing frictioning bar base.
Further, angle theta is 50 ~ 120 ° between the long side of the auxiliary printed panel and minor face.
Further, the length of the auxiliary printed panel shorter edge width a is 2 ~ 15mm.
Further, the auxiliary printed panel shorter edge and the main printing frictioning bar base are 2 ~ 15mm apart from h.
Further, the auxiliary printed panel width is equal with the main printing frictioning bar.
In sum, due to adopting above-mentioned technical proposal, the invention has the beneficial effects as follows：
The present invention is made up of one piece of main frictioning bar and one piece of auxiliary printed panel, the section of auxiliary printed panel is L-shaped, the glass-fiber-plate of longer one side laminating frictioning bar is simultaneously mounted above, its short face then leaves certain distance with the bottom of frictioning bar, aids in the short face of printed panel not contact with silk screen surface during printing.In printing, the short face for aiding in printed panel plays preprinted effect, in ink or the previously extruded opening to silk screen of silver paste, subsequently will again have the frictioning bar contacted with half tone extruding printing to go down.By this design so that the printing scraping article is provided with the effect of secondary printing, so as to reach strike through amount is increased, improve the high purpose of track, the photoelectric transformation efficiency of cell piece may finally be improved.
Description of the drawings
Fig. 1 is the structural side view of the present invention；
Fig. 2 is present configuration front view；
Fig. 3 is working state structure schematic diagram of the present invention.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 and 2, a kind of new serigraphy frictioning bar, including main printing frictioning bar 1, also including the auxiliary printed panel 2 that a section is L-shaped, the auxiliary width of printed panel 2 is equal with the main printing frictioning bar 1；The auxiliary longer sides of printed panel 2 are connected with face with the glass-fiber-plate one side of the main printing frictioning bar 1 by bolt or bonding, its shorter edge 2 ~ 15mm of width, and shorter edge has certain distance h with main printing frictioning bar 1 base, and this is 2 ~ 15mm apart from h；Angle theta is 90 ° between the auxiliary long side of printed panel 2 and minor face.
The present invention increases by one piece of L-shaped and aids in printed panel 2 by the printing surface in former printing frictioning bar, aids in the width a of the minor face of printed panel 2 and with main printing frictioning bar 1 bottom apart from h by appropriate design L-shaped, thus it is possible to vary squeezing action of the auxiliary printed panel 2 to slurry.In general, a increases, and when h is reduced, auxiliary printed panel 2 is more apparent to the squeezing effect of slurry, can increase strike through amount.If when h is too low, slurry is difficult to enter into below auxiliary printed panel 2, and printing strike through will be reduced.When a excessively hours, also due to its active area is reduced, cause the squeezing action to slurry limited, affect strike through ability.So the optimization of a and h, the selection of minor face angle, θ has an impact to printing effect, how to be the key problem in technology of this scraping article according to slurry, half tone and print request optimum choice these three parameters, and aid in the minor face of printed panel 2 not contact half tone to be preferred, and slurry can repeatedly be entered and is preferred.
As shown in figure 3, during printing, main printing frictioning bar 1 promotes slurry（Lower section shadow region in figure）Motion, slurry rolls advance between main frictioning bar 1 and half tone 3.When slurry before main printing frictioning bar 1 is enough, the minor face of auxiliary printed panel 2 will apply one perpendicular to downward power F2 of minor face to slurry, this power F2 in advance can be expressed to slurry in the opening of half tone 3, subsequently power F1 is applied again to slurry by main frictioning bar 1, most at last slurry is squeezed in half tone 3 is open F1.Because slurry is previously extruded once by the minor face of auxiliary printed panel before main printing frictioning bar extruding, therefore the strike through amount of the printing of entirety is dramatically increased, and increased the height of grid line.
Experimental data：
Former main printing frictioning bar strike through amount is 0.0582g, and Design assistant printed panel bond length a of the present invention is 6mm, and minor face is 5.77mm apart from h with main printing frictioning bar base, and angle theta is 90 ° between long side and minor face, and strike through amount is 0.0635g, and strike through amount increases by 9.20%.
Presently preferred embodiments of the present invention is the foregoing is only, not to limit the present invention, all any modification, equivalent and improvement made within the spirit and principles in the present invention etc., be should be included within the scope of the present invention.
