The invention discloses automatic test equipment for a PTC heater, relates to PTC heater production and processing equipment, and aims at solving the problems that the existing PTC heater aging test needs manual operation which is relatively unsafe and has low test efficiency. The key points of the technical scheme are that the automatic test equipment comprises a frame body, a circulating objectmoving device and an aging test device. The circulating object moving device comprises a driving belt and multiple object stages. Multiple object stages are arranged along the length direction of thedriving belt. The aging test device comprises a high and low voltage switching mechanism and a detection and judgment mechanism. When the object stages move, the high and low voltage switching mechanism automatically switches high and low voltage. The detection and judgment mechanism is arranged on the object stages and is electrically connected with the high and low voltage switching mechanism and the PTC heater. According to the automatic test equipment for the PTC heater, the aging test and the insulation withstand voltage test can be automatically performed on the PTC heater so as to reduce safety hidden troubles and improve work efficiency.
