The invention discloses full-automatic feeding and discharging and multi-
station appearance detecting and sorting equipment and method for small parts. The equipment comprises a material disc feeding mechanism, a product feeding and discharging
station, a product
transplanting mechanism, a product secondary positioning
station, a product detection objective table, a product detection station, a sorting and material changing station, an OK product and NG product sorting mechanism, an NG product placing station, an OK product supplementing and placing station, and an OK product whole disc output mechanism. A material disc reaches a product feeding and discharging station through the material disc feeding mechanism and is moved to a product secondary positioning station through the product
transplanting mechanism, the product detection objective table moves and adjusts the angle of a product to detect all the angles of the product, and the OK product and NG product sorting mechanism sorts NG products in the material disc and supplements the OK products at vacant positions. The whole
layout design is compact, the space position is fully utilized, the
automation degree is high, the production efficiency is high, the compatibility is high, the equipment can be suitable for trays and products of different specifications, and the product detection range is wide.
