Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaics and relates to a device for selecting high-quality surfaces of crystal rods. Background Art

[0002] In the field of automation in the photovoltaic industry, square silicon rods need to be suspended upside down and placed in a slicer to be cut into thin silicon wafers. The cut crystal rods may be 950mm long rods, or they may be 950mm long rods made by splicing multiple short rods less than 950mm. The two end faces of the square rods are basically inclined planes, so when splicing the crystal rods, it is necessary to ensure that the joints of the two square rods meet the requirements of wide top and narrow bottom (i.e. "V" shape) to avoid the slicer damaging the cutting line when cutting the spliced ​​crystal rods.

[0003] In the process of transporting and splicing square silicon rods, the end faces of the silicon rods cannot always be guaranteed to be in a "V"-shaped connection state. To achieve this effect, it is also necessary to detect the direction of the end faces of the crystal rods in advance before splicing. The traditional method uses manual and some detection equipment to participate in the detection, and then make subsequent direction adjustments. This has high labor costs and production costs; second, the manual operation risk is high and there are hidden dangers; third, the accuracy is not high. Sometimes the end face direction is inaccurate and there are errors. Affecting subsequent processes. Utility Model Content
