Abstract
The invention relates to the technical field of photovoltaic screen printing, and provides a screen damage detection method, a screen damage detection system and a screen printing device. The screen damage detection method comprises the following steps of acquiring an image, namely performing image acquisition on a screen to obtain a screen image; processing the image, namely processing the information of the screen image to obtain a gray value of the screen image; judging the damage condition, namely judging the damage condition of the screen according to the gray value of the screen image, wherein the damage condition of the screen comprise fractures and cracks. According to the invention, the screen can be found in time when being damaged, so that a worker can replace the screen in time, the problem that a plurality of table boards need to be cleaned due to the fact that the screen cannot be found in time is effectively avoided, the time consumed for cleaning the table boards can be effectively saved, and meanwhile, the device operation efficiency and the product percent of pass can be improved.
Description
technical field [0001] The invention relates to the technical field of photovoltaic screen printing, in particular to a screen damage detection method, a screen damage detection system and screen printing equipment. Background technique [0002] At present, most photovoltaic manufacturers use the screen printing method to prepare electrodes and electric fields for cell sheets. Among them, the process of replacing the screen plate is involved. This process is indispensable in the screen printing process and can only be optimized for the purpose of reducing the time-consuming of screen plate replacement. The old replacement method is that the cell rotates to the printing station through the mechanism. When the cell stops at the printing station, the scraper scrapes the paste onto the cell through the pattern on the screen, and the screen will appear during the scraping process. If the screen is damaged (the service life of the screen is over, there are hidden cracks in the ba...
