SUCTION HEAD OF ELECTRONIC PART MOUNTING MACHINE

摘要

An object of the present invention is to offer a component suction head for electronic component mounting machines which is capable of securely holding electronic components by suction and smoothly mounting them on printed wiring boards without dislocation. To achieve the objective, the component suction head of the present invention comprises the following. A suction nozzle unit 24 has a suction face 33 at the center of its tip, for holding electronic component 10, and a through hole 27 formed at its center which leads to the suction face 33. The back end of the through hole 27 is connected to a vacuum generator. An elastic ring 32 is fitted and fixed around the through hole 27 to the tip of the suction nozzle unit 24, slightly protruding from the suction face 33. An ejector pin 28, which can protrude from the suction face 33 for a specified length, forms an intake passage 38 from the tip to the through hole 27, and is fitted to the through hole 27 in sliding fashion. A spring means 31 supports the tip of the ejector pin 28 to protrude from the suction face 33.
