Precise part inspection and detection equipment with automatic feeding function and method

The invention discloses precision part inspection and detection equipment with an automatic feeding function and a method. The precision part inspection and detection equipment comprises a cleaning bin, an inspection bin is arranged on one side of the cleaning bin, a sliding opening and a conveying opening are formed in the other side of the cleaning bin, and another conveying opening is formed in the other end of the inspection bin; a conveying ring is slidably connected into the sliding opening, a first rotating rod can rotate when a motor in the first motor box is started through the arranged first motor box, so that the conveying ring rotates, a threaded rod can rotate when a second motor box in the feeding barrel is started through the arranged first electromagnet and the first electromagnet carries out rotary descending. And when the conveying ring rotates the feeding barrel to the position of the limiting groove, the parts in the limiting groove are sucked, then the parts are rotationally collected int
