Problems solved by technology

However, after the rotating electromagnet reaches the specified angle position, it will rebound due to the inertial reaction force due to power failure and loss of power, resulting in the collision of the guide wheel of the transport vehicle with the aerial guide rail, or even jamming, which seriously affects the aerial space. The normal operation of the transport vehicle reduces the production efficiency of the semiconductor factory

Abstract

The invention provides a steering control method and system of an aerial transport vehicle, which are applied in the technical field of semiconductor wafer manufacturing equipment, wherein the steering control method of the aerial transport vehicle includes: when steering control is required, first apply The first driving voltage drives the guide wheel to move on the slide rail through the electromagnet to cooperate with the air guide track for steering guidance; when the guide wheel moves to the first designated position on the slide rail, switch to apply the second drive to the electromagnet Voltage, and after the guide wheel moves to the second specified position on the slide rail, continue to apply the third driving voltage to the electromagnet before powering off. By applying different driving voltages to the rotating electromagnet, the rotating electromagnet is in different working states in the steering control, effectively improving the temperature rise of the electromagnet, and improving the rebound phenomenon of the electromagnet due to power failure that affects the guide wheel and the ground. Coordination between guide rails.

Description

technical field [0001] The invention relates to the technical field of semiconductor wafer manufacturing equipment, in particular to a steering control method and system for an air transport vehicle in an automatic material handling system. Background technique [0002] In the application of semiconductor automation factory, the air transport vehicle in the automatic material handling system (AMHS, Automatic Material Handling System, also known as the overhead crane system) needs to transport the target clamping object from one place to the designated position as required. The position of the round box) and the target conveying position are not on the same track, then the transporter needs to change the track to walk. At this time, the rotating electromagnet in the steering drive mechanism on the transporter moves the guide wheel on the slide rail to the specified position and moves. Change the walking track of the transporter under the interference of the upper guide rail. ...
