Semiconductor box automatic switching system

Abstract

This invention discloses an automatic switching system for a semiconductor box, comprising a lifting platform and at least one switching device. The cover-holding module of the lifting platform is connected to a lifting mechanism via a connecting frame. The switching device is connected to the connecting frame of the lifting platform, with its unlocking module connected to a first reciprocating motion unit and its closing module connected to both the first and second reciprocating motion units. Thus, the cover-holding module and the connecting frame are moved vertically by the lifting mechanism, causing the unlocking and closing modules to move to positions aligned with the latch of the semiconductor box. The first reciprocating motion unit then drives the unlocking module to open the latch, or the first and second reciprocating motion units drive the closing module to lock the latch.
