Description

Technical field[0001]The invention relates to a saggar flatness detection, in particular to a saggar flatness detection device based on binocular structured light and a detection method thereof.Background technique[0002]A sagger is a kind of kiln furniture made of refractory materials, which is used to contain reaction materials in the production of electrode materials. In the existing production process, the electrode calcination temperature is high, and some raw materials are highly corrosive during the reaction. The sagger needs to withstand higher thermal stress and corrosion of the reaction materials, resulting in uneven pits and rough undulations in the sagger Of small pieces. Damaged saggers can easily fall off their own powder, causing pollution of the raw materials it contains, seriously affecting product quality and causing additional economic losses to the enterprise.[0003]At present, the flatness of saggars on the market is generally inspected manually. It is easy to cau...
