The invention provides a chip center positioning device, which relates to the technical field of a chip center positioning device which is semiconductor special equipment. A chip supporting table and a shaft are arranged on a central plate; the shaft is connected with a rotating disk through a bearing, and is fixed to a base; the rotating disk is connected with an electric motor through a mechanical driving device; the central plate is provided with at least three strip-shape radial holes; a crank hook mechanism is respectively arranged between each strip-shape radial hole and the rotating disk; one end of each crank hook mechanism is twisted with the rotating disk, and the other end is in sliding fit with the strip-shape radial holes through a positioning side twisted on the crank hook mechanism. The chip center positioning device solves the technical problems of high control difficulty and complicated structure of a traditional chip center positioning device, and has the characteristics of simple and compact structure, stable operation, high reliability and convenient use. The chip center positioning device is particularly suitable for the semiconductor special equipment for processing a chip.
