Abstract
Description
Technical Field
[0001] The utility model relates to the field of photovoltaic silicon wafer production equipment, in particular to an image acquisition device for a wire trough wire network. Background Art
[0002] The production of silicon wafers mainly relies on diamond wire cutting technology, which uses diamond wire to cut silicon rods at high speed to produce thin silicon wafers. The arrangement and tension control of the diamond wire are crucial to the stability and cutting quality of the cutting process.
[0003] However, the existing diamond wire detection methods mainly rely on manual operation, including using a mobile phone or microscope to shoot the diamond wire grooves and wire nets on the main roller, and then manually marking and counting them after magnification. However, given that the size of the diamond wire and its grooves is extremely small (only tens of microns) and densely arranged, the working conditions inside the cutting machine are poor, and there are interferences such as mortar liquid and mortar pipes, manual shooting is difficult and counting accuracy is limited, which can easily lead to detection errors.
[0004] In addition, traditional manual inspection is usually carried out under a single lighting environment, which limits the comprehensive presentation of the details of the diamond wire, thereby increasing the possibility of false detection and missed detection. At the same time, due to the inherent limitations of the imaging field of mobile phones and microscopes, these traditional inspection methods are often only applicable to a smaller range of inspections and cannot cover a wider inspection area.
