Patent ID: 7594571

Claim:
A conveying device for testing heat dissipating fans, which is suitable for testing multiple heat dissipating fans at the same time, comprising: a base; a conveying unit, being mounted to the base and further comprising a conveying element and an actuating element, which actuates the conveying element to move; a plurality of movable loading tables, being placed on the conveying unit and delivered by the conveying element, each of the movable loading tables further comprising a support plate, a test circuit on the support plate and a first and second conductive plates, which are disposed at the bottom of the support plate and spaced apart from each other; a first conductor rail unit, being disposed below each of the movable loading tables, having a first locating plate, which is fixedly attached to the base, and a plurality of first micro conductor rails, which are provided on the first locating plate to space from each other, wherein, each of the first micro conductor rails electrically connects with each other and further comprises a first main member and a first conductive spring plate, which is resiliently mounted to the first main member and is capable of contacting the first conductive plate; and a second conductor rail unit, being disposed under each of the movable loading tables to space apart the first conductor rail unit, providing a second locating plate and a plurality of second micro conductor rails, which are provided on the elongated locating plate and space from each other, each of the second micro conductor rails further comprising a second main member and a second conductive spring plate, which is resiliently mounted to the second main member and is capable of contacting the second conductive plate; whereby, once the first and second conductor units are charged with positive and negative current respectively, the positive and negative current is capable of being sent to the test circuit such that each of the heat dissipating fans, which is placed on the movable loading tables respectively and electrically connects with the test circuit, is capable of being performed with operation test during moving.
