Abstract
The utility model relates to the field of manufacturing crystalline silicon solar cells and provides a device for cleaning silicon wafers before printing. The device comprises a hairbrush, an air knife and a bracket used for fixing the hairbrush and the air knife; the hairbrush is arranged in parallel to the air knife and forms an angle of 90 degrees with the horizontal plane of the rotation direction of a printing platform; and the blowing direction of the air knife and the rotation direction of the printing platform form an angle of 30-60 degrees on the vertical surface. The device of the utility model has the advantages that the cracking rate of screen printing plates caused by particles or fragments existing on the surfaces of silicon wafers can be greatly reduced, the cost can be saved, and the device is convenient and practical.
Description
Technical field
The utility model relates to the printing equipment field of crystal silicon solar energy battery, is specifically related to clear up silicon chip devices before a kind of printing.
Background technology
Along with the development of photovoltaic industry, the raising of battery efficiency, the reduction of cost have become the basic of whole photovoltaic industry development existence.An important step during printing process is made as the conventional crystal silicon solar cell, and at present along with the requirement to efficient and outward appearance, the quality and the manufacturing cost of printing screen plate are more and more higher, directly affect the cost of battery sheet.And in printing process, by particle on the silicon chip and fragment bursting, this situation directly makes the cost of manufacture of battery sheet increase to half tone through regular meeting.
Summary of the invention
The purpose of this utility model is exactly a cleaning silicon chip devices before a kind of printing that provides at the defective of above-mentioned existence, and this will improve the average use birthday noodle of half tone greatly, reduce the production cost of battery sheet.
The device technique scheme of removing silicon chip surface particle and fragment before a kind of solar cell printing of the present utility model is, comprises hairbrush, air knife, and the fixing support of hairbrush and air knife is installed on the position between the print head and paper platform to be printed on the silicon chip printing machine.
Described hairbrush, the soft hair of its Mao Zhiwei, its hardness can not destroyed the anti-reflection passivating film of silicon chip surface.
Described hairbrush becomes an angle of 90 degrees with the rotation direction of printing platform on horizontal plane, when the printing paper platform from the below of hairbrush through out-of-date, guarantee that hairbrush can sweep to each corner of printing paper platform.
Described air knife, consistent with the installation direction of hairbrush, the direction of air knife blowing becomes 30-60 degree angles with the printing platform rotation direction on vertical plane.
The beneficial effects of the utility model are: a kind of device of removing silicon chip surface particle and fragment before printing of the present utility model, comprise hairbrush, air knife, the fixing support of hairbrush and air knife, the parallel installation of described hairbrush with air knife, with become an angle of 90 degrees on the rotation direction horizontal plane of printing platform, the direction of air knife blowing becomes 30-60 to spend angles on vertical plane with the printing platform rotation direction.Silicon chip is firmly inhaled on the printing paper platform by vacuum, when printing platform rotates, through the utility model device, at first the big fragment of silicon chip surface is brushed by hairbrush, blow off by the air knife of back granule then, make the silicon chip surface below the print head clean as far as possible, guarantee not have the particle that can cause half tone to break silicon chip surface, improve the average use birthday noodle of half tone greatly, reduced the production cost of battery sheet.Because the soft pure wool that adopts, in the process of printing front electrode, hairbrush can not destroy the anti-reflection passivating film of silicon chip surface, has avoided causing the electric leakage of battery sheet.This device is convenient and practical, is suitable for industrial production.
Description of drawings:
Figure 1 shows that the utility model structural representation.
Among the figure, 1. print head, 2. air knife, 3. support, 4. hairbrush, 5. printing paper platform, 6. printing platform.
The specific embodiment:
In order to understand the utility model better, describe the technical solution of the utility model in detail below in conjunction with accompanying drawing, but the utility model is not limited thereto.
A kind of crystal silicon solar energy battery of the present utility model is removed the device of silicon chip surface particle and fragment before printing, comprise hairbrush 4, air knife 2, the fixing support 3 of hairbrush 4 and air knife 2, be installed on the position between the print head 1 and paper platform 5 to be printed on the silicon chip printing machine, described hairbrush 4 and air knife 2 parallel installations and become an angle of 90 degrees on the rotation direction horizontal plane of printing platform 6, and the direction of air knife 2 blowings becomes 30-60 to spend angles on vertical plane with printing platform 6 rotation directions.
Described hairbrush 4, the soft hair of its Mao Zhiwei, its hardness can not destroyed the anti-reflection passivating film of silicon chip surface.
Silicon chip places on the printing paper platform 5, firmly inhaled on printing paper platform 5 by vacuum, when printing platform 6 rotates, silicon chip on the printing paper platform 5 is at first through being fixed on the hairbrush 4 and air knife 2 on the support 3, at first the big fragment of silicon chip surface is brushed by hairbrush 4, blown off by the air knife 2 of the back granule with silicon chip surface then, the silicon chip of being cleaned out enters print head 1 subsequently and prints.
Claims (3)
1. cleaning silicon chip devices before the printing is characterized in that, comprises hairbrush, air knife, and the fixing support of hairbrush and air knife is installed on the position between the print head and paper platform to be printed on the silicon chip printing machine.
2. the cleaning silicon chip devices is characterized in that described hairbrush becomes an angle of 90 degrees with the rotation direction of printing platform on horizontal plane before a kind of printing according to claim 1.
3. the cleaning silicon chip devices is characterized in that before a kind of printing according to claim 1, and described air knife is consistent with the installation direction of hairbrush, and the direction of air knife blowing becomes 30-60 degree angles with the printing platform rotation direction on vertical plane.
