Abstract
The utility model discloses a scraper device for screen printing, which comprises a support, a scraper body and a fastening clamping strip; the scraper body is fixedly clamped between the support and the fastening clamping strip; the cross section of the scraper body is rectangular; an angle alpha formed by a surface on which the scraper body is located and the plane is 30 to 70 degrees; and the length of the scraper body which extends out of the bottom end of the support is 2 to 6cm. The scraper body has good elasticity and flexibility, can go up and down with the state of the surface of a silicon wafer when in printing, has good buffering effect, and prevents a matrix (such as the silicon wafer) from being crushed when in screen printing.
Description
Technical field
The utility model relates to a kind of doctor blade device that is used for serigraphy.
Background technology
At present, the lasting use of conventional energy resource has brought a series of economy and social concerns such as energy scarcity and ecological deterioration, the development solar cell be address the above problem by way of one of.The manufacturing process of existing manufacturing crystal-silicon solar cell is: surface clean and texturing, diffusion, etching trimming, coated with antireflection film, serigraphy, sintering form Ohmic contact, test.This commercialization crystal silicon cell manufacturing technology is simple relatively, cost is lower, is fit to industrialization, automated production, thereby has obtained extensive use.Wherein, serigraphy is the positive and negative electrode that is used to prepare solar cell, the electrocondution slurry that the making of electrode need use noble metal silver to make, for obtaining photoelectric transformation efficiency preferably, conductive silver slurry must be printed uniformity as much as possible, and certain thickness is arranged, with shading loss that reduces electrode and the series resistance loss that electrode resistance brings; Therefore, for the front electrode of crystal silicon solar energy battery, the quality of its printing has directly influenced the photoelectric transformation efficiency of crystal silicon solar energy battery.
Existing doctor blade device is referring to shown in the accompanying drawing 1～2, mainly comprise support 1, scraper main body 2 and fastening clamp bar 3, the scraper main body is fastened between support and the fastening clamp bar, described scraper main body adopts polyurethane rubber to make usually, its cross section is a square, and cutting edge and stock are miter angle during printing.
The cushioning effect of scraper was less when the subject matter that above-mentioned doctor blade device exists was printing, the electrode uniformity of printing is relatively poor, and, when carrying out the slurry serigraphy, be very easy to broken because the thickness of the silicon chip of existing crystal silicon solar energy battery generally only has about 180um.
Summary of the invention
The utility model purpose provides a kind of doctor blade device that is used for serigraphy, to improve the quality of serigraphy.
For achieving the above object, the technical solution adopted in the utility model is: a kind of doctor blade device that is used for serigraphy, comprise support, scraper main body and fastening clamp bar, the scraper main body is fastened between support and the fastening clamp bar, the cross section of described scraper main body is a rectangle, and the plane at scraper main body place and the angle a between the horizontal plane are 30～70 degree; The length that the scraper main body is stretched out the support bottom is 2～6cm.
Above, described scraper main body is fastened between support and the fastening clamp bar, and the three can adopt thread connecting mode, and promptly the three is equipped with the screwed hole of cooperation, and is bolted to connection.The length that described scraper main body is stretched out the support bottom is meant oblique self length of stretching out of scraper main body.Preferred scheme, described support is set as shape of BU, thereby the top of scraper main body is butted in the support, improves both fastening degree.
Further technical scheme, the plane at described scraper main body place and the angle a between the horizontal plane are 50～70 degree.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, the utility model is set as cuboid with the scraper main body, and make the scraper main body stretch out the support bottom, cooperate the angle between scraper main body and the horizontal plane, make the scraper main body of doctor blade device have better elastic and pliability, the scraper main body can rise and fall along with the state of silicon chip surface when printing, has good cushioning effect, the fragmentation of matrix when having avoided serigraphy (as silicon chip).
2, the utility model will be designed to certain angle between scraper main body and the horizontal plane, the cutting edge of scraper main body can be combined closely with silk screen during printing, guaranteed the good line contact between silk screen and the matrix (as silicon chip), the most slurries in printing back can see through mesh and arrive on the matrix, almost there is not residual slurry in the mesh, the slurry justifying that prints out is had good uniformity, and grid line height unanimity has good printing quality.
3, the utility model is simple in structure, be convenient to produce preparation, and cost is lower, is suitable for applying.

Fig. 1 is the cutaway view of doctor blade device in the background technology;
Fig. 2 is the front view of doctor blade device in the background technology;
Fig. 3 is the cutaway view of the utility model embodiment one.
Wherein: 1, support; 2, scraper main body; 3, fastening clamp bar; 4, bolt.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one
Referring to shown in Figure 3, a kind of doctor blade device that is used for serigraphy, comprise support 1, scraper main body 2 and fastening clamp bar 3, scraper main body 2 is fixedly connected between support 1 and the fastening clamp bar 3 by bolt 4, the cross section of described scraper main body 2 is a rectangle, and the plane at scraper main body place and the angle a between the horizontal plane are 60 degree; The length that the scraper main body is stretched out the support bottom is 4cm.
Above, the plane at described scraper main body place and the angle a between the horizontal plane are referring to shown in Figure 3.The length that described scraper main body is stretched out the support bottom is meant oblique self length of stretching out of scraper main body.Described support is set as shape of BU, thereby the top of scraper main body is butted in the support, improves both fastening degree.
Claims (2)
