Abstract

The invention discloses a stretcher and a high-precision stretching method for a secondary screen printing plate. The stretcher comprises a table body (1) and a plurality of screen clamping devices (2), wherein the screen clamping devices (2) are mutually independent and are arranged on the table body (1); each screen clamping device (2) comprises a rapid clamp (6) and a linear driving mechanism (4) for driving the corresponding rapid clamp (6) to move. The high-precision high-precision stretching method conducted by using the stretcher for the secondary printing screen comprises the steps ofclamping the stainless steel silk screen, carrying out local correction, carrying out shaping treatment, carrying out gluing and cutting off the redundant parts of the stainless steel silk screen, wherein in the step of carrying out local correction, the regions, which is bent and deformed, of the stainless steel silk screen are found out through photographing and scanning and then are subjected to local adjustment and correction. According to the stretcher and the high-precision stretching method, the printing precision in the photovoltaic printing process can be improved, the conversion efficiency can be improved while the unit consumption of a sizing agent is not increased, the efficiency can be improved by 0.1% to 0.2%, the photoelectric conversion efficiency can be effectively improved, and the service life of the screen printing plate can be effectively prolonged.

Description

technical field [0001] The invention relates to a net stretching machine and a high-precision net stretching method for a secondary printing screen plate. Background technique [0002] At present, in the field of photovoltaic printing, the secondary printing process is still an important way for photovoltaic enterprises to improve efficiency and reduce costs. The development of secondary printing screen high-precision stretching process and changing the traditional stretching process will be able to pass through for plate making companies. Reduce line width, increase printing accuracy and stack paste effect, effectively improve photoelectric conversion efficiency and screen life. However, due to the low accuracy of screen overprinting, there are still problems such as alignment deviation and printing boldness. The clamping device for clamping the steel wire mesh of the current net stretching machine can only adjust the steel wire mesh as a whole, and cannot fine-tune the pa...
