The invention relates to the technical field of an inserter of a horizontal electronic element, in particular to a drive-free electronic element centering device. The drive-free electronic element centering device comprises a fixed base, a support beam, a centering base body and a connecting member, wherein the centering base body is provided with two rotating shafts in parallel, clamping member seats are respectively arranged at the lower ends of the two rotating shafts and fixedly provided with centering members; a spring is arranged between the two clamping member seats, one end of the spring is connected with the tail part of one of the clamping member seats, and the other end of the spring is connected with the tail part of the other clamping member seat; and a material ejecting member is arranged below the centering base body, and the upper surface of the material ejecting member is connected with the lower edges of the two centering members in a propping manner simultaneously. According to the drive-free electronic element centering device, the running is rapid, the centering accuracy of the electronic element is high, the centering operation can be realized without driving mechanisms such as an air cylinder or a motor, the structure of the centering device is simplified greatly, the production cost and the rear-stage maintenance cost are lowered, the reaction efficiency of the centering operation is improved, and the practicability is strong.
