Technical Field

The invention relates to a scraper, in particular to a cutter for scraping silver paste adhered to a silver paste tank, a screen plate or a common silver paste scraper.

Background

In the photovoltaic industry, silver paste can meet many emergency situations such as screen plate replacement, slurry experiments, plate explosion, scraper replacement and the like when being used in batches by solar cell manufacturers, and the existing production line coping method is very single and rough when meeting the situations.

The existing methods for receiving the slurry include:

A. the method can store most of the slurry, but the slurry on the screen plate cannot be completely scraped clean, and the slurry is more difficult to clean after being dried for a long time.

B. And (5) recovering the slurry on the screen plate by using a stirring rod of the production line slurry, and then further storing the residual slurry by using an old scraper. This method can be stored more cleanly than the previous method, but the old doctor blade easily damages the screen plate, and is not clean yet, and is easily exposed to secondary contamination.

C. The method is almost the same as the previous method in that the old scraper is directly used for recycling the slurry on the screen plate, and the slurry is always scattered everywhere after the stirring rod is removed and the slurry is primarily recycled, so that the working area is easily polluted.

D. The method can effectively save the waste of the slurry by using a self-made containing tool to contain the slurry, but the tool is easy to mix, and secondary pollution is caused.

No matter which kind above receives the mode of thick liquids can only take in totally with the thick liquids on the otter board by force, and the thick liquids on the silver thick liquid scraper can't be with silver thick liquid scraper clean up owing to lack the instrument of suitable size, will shine into the waste of partly silver thick liquid like this. In addition, because the silver thick liquid has certain viscosity for deposit the thick liquids of silver thick liquid and irritate inside more or less can all adhere some silver thick liquids, and because the tank bottoms of silver thick liquid jar all is provided with the chamfer, ordinary scraper is difficult to get totally silver thick liquid of gluing in the silver thick liquid jar is scraped.

Disclosure of Invention
