A multi-track detection system for detecting the appearance of electronic elements includes a rotary module, a feeding module, an unvibrated module, a detection module, and a classification module. The rotary module includes a hollow transparent rotary structure having at least two annular guiding areas on the top surface thereof, and the electronic elements are sequentially arranged on the two annular guiding area. The feeding module has two V-shaped feeding grooves for guiding the electronic elements. The unvibrated module includes an unvibrated guiding block having two V-shaped unvibrated guiding grooves respectively communicated with the two V-shaped feeding grooves and respectively corresponding to the two annular guiding areas. The electronic elements on the V-shaped feeding grooves are sequentially transmitted onto the two annular guiding areas through two V-shaped unvibrated guiding grooves, thus each electronic element can be detected by the detection module and classified by the classification module, respectively.
