新型圆筒形网版光伏玻璃丝印方法

Cylindrical Screen Printing Method for Photovoltaic Glass

用于光伏背板玻璃丝网印刷的设备是由汽车玻璃丝网印刷设备改进而来的,虽然能满足基本需求,但是存在生产效率低、易糊版、网版清洁困难等问题。提出一种圆筒网版丝印机,采用圆筒形网版机构做圆周运动,同时玻璃做直线运动,油刀和刮刀机构配合将油墨印刷到玻璃上表面,吸盘组件再将背板玻璃送至检验输送段。圆筒形网版机设置两套并行,可实现不停机换网版、自动清洁网版等功能,避免了传统丝印每次换网版后的间歇操作。

The equipment used for photovoltaic backplane glass screen printing is transformed from automotive glass screen printing equipment.Although it can meet the basic needs,it has many problems such as low production efficiency,easy to paste,and screen cleaning difficulty.This paper proposes a cylindrical screen mechanism that moves in circle,while the glass moves in a straight line.The oil knife and the scraper mechanism cooperate to print ink on the upper surface of glass,and the suction cup assembly sends the back glass to the inspection conveying section.The cylindrical screen mechanism is set up with two parallel sets,which can realize the functions such as non-stop screen change,automatic screen cleaning,etc.,eliminating the necessary of intermittent operation after each screen change in traditional screen printing.
