JPS5764945A - Inspecting device for electronic parts - Google Patents

Abstract

PURPOSE:To enhance the reliability of an inspection for an electronic part and to prevent the variation in the directivity of the part and the damaging the mark of the part by containing the part on a plurality of rails laid on the peripheral surface of a truncated drum in a constant-temperature bath, heating the path therein and inspecting the characteristics of the part in the bath and sorting the parts. CONSTITUTION:A drum 2 radially arranged with part containing rails 3 is supported at the center by a rotationary shaft 22 in an operating temperature inspecting device, and is arranged together with an inspecting mechanism 20 and a sorting mechanism 34 in a constant-temperature bath 1. The part 5 in a magazine 7 is fed from an opening 5 slidably into a supply chute 4 in the oven 1, and the parts 5 are separated and contained by an isolating mechanism 12 in the amount on each rail. When the drum 1 rotates approximately one revolution, the part 5 is heated to the prescribed temperature, and when it is fed to the position before one pitch from the supply unit, a stopper 29 is opened, and the part is fed to the inspecting mechanism 20. The part 5 is sorted to the mechanism 34 in accordance with the propriety of the inspected result of the characteristics of the part, and is sorted to any of the chutes 35, 36 out of the oven to be conveyed. Since it is inspected at the treating temperature, the inspecting reliability can be enhanced, and since the part is not inverted by the rotation of the drum, it can prebent the damage of the mark and the variation in the directivity of the part.
