Abstract:
1. A distance adjustment system for use in a solar wafer inspection machine adapted for inspecting solar wafers having various width dimensions, wherein the solar wafers each have a light receiving surface and a plurality of conductive buses formed on the light receiving surface and adapted for outputting electric energy converted from incident light, the conductive buses being spaced apart from one other in way of corresponding to the width dimension of the corresponding solar wafer, and wherein the inspection machine comprises a conveying system for carrying the solar wafers along a conveying path, an optical inspection system mounted in corresponding to at least one image pickup position along the conveying path, and an illumination inspection system mounted in corresponding to at least one opto-electrical inspection position along the conveying path, the distance adjustment system comprising: a plurality of registering devices, each comprising a holder for maintaining one of the solar wafers in position along its width direction when the solar wafer is transferred by the conveying system to the at least one image pickup position or the at least one opto-electrical inspection position; and an adjustment device that performs adjustment based on sizes of the solar wafers, comprising:
