Abstract

The present disclosure related to a stacker of an electric device test hander comprising an upper stacker and a lower stacker. Stacker modules provided in the upper stacker can be opened and closed by being moved horizontally from the frame, and each of stacker modules can give and receive a plurality of user trays to and from the lower stacker in closed position. According to present disclosure when goods are being transferred to and from the outside, the user trays can move freely between the loading parts disposed on the upper and lower sides. Thus, the dependence on the visitation cycle of an external robot and the replacement amounts of the user trays can be lowered to improve ease of operation.
