Solar silicon wafer two-in-one automatic loading and unloading equipment

Abstract

The invention discloses solar silicon wafer two-in-one automatic loading and unloading equipment, which is characterized in that a loading module and an unloading module are respectively located at two sides of a lifting platform, a transferring module is arranged above a discharging port of the loading module and a feeding port of the unloading module, the lifting platform is butted with a feeding and discharging end of main equipment along a Y moving direction of a carrier plate, the discharging port of the loading module and the feeding port of the unloading module respectively correspond to two sides in the X-direction of the feeding and discharging end of the main equipment; the lifting platform comprises an upper discharging station and a lower feeding station, the upper discharging station is butted with the discharging port above the feeding and discharging end of the main equipment in the Y-direction, and the lower feeding station is butted with the feeding port below the feeding and discharging end of the main equipment in the Y-direction; the unloading module comprises CCD detection module, an eliminating device and a lamination structure; and the lamination structure enables dropped silicon wafers to be neatly stacked by using a principle of automatic positioning of an oblique plane, thereby enabling the silicon wafer to be directly stacked into a block shape so as to be convenient for being directly packaged and transported, and greatly improving the product packaging efficiency.

Description

technical field [0001] The invention relates to an automatic equipment, in particular to a two-in-one automatic loading and unloading equipment for solar silicon wafers used in the dry texturing, PECVD coating and other treatment processes of solar battery silicon wafers. Background technique [0002] In recent years, the requirements for environmental protection have become higher and higher, the pollution of fossil energy has been paid more and more attention, and due to the non-renewable nature of fossil energy, it is imminent to seek new forms of energy. Among many new energy sources, photovoltaic power generation technology stands out. Silicon wafers are the core components in photovoltaic power generation technology, and there are many processes for producing solar silicon wafers, including silicon material purification, ingot casting, squaring, and slicing in the early stage, to texturing, diffusion, cleaning, PECVD coating, and slicing in the later stage.
