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 for an air transport vehicle, and is applied to the technical field of semiconductor wafer manufacturing equipment.The steering control method for the air transport vehicle comprises the steps that when steering control is needed, first driving voltage is applied to an electromagnet used for steering control guiding, and the electromagnet drives a guide wheel to move on a sliding rail; steering guiding is carried out in cooperation with an air guide rail; when the guide wheel moves to a first designated position on the sliding rail, the second driving voltage is applied to the electromagnet, and after the guide wheel moves to a second designated position on the sliding rail, the third driving voltage is continuously applied to the electromagnet, and then the power is cut off. Different driving voltages are applied to the rotating electromagnet, so that the rotating electromagnet is in different working states during steering control, the temperature rise condition of the electromagnet is effectively improved, and the situation that the electromagnet rebounds due to power failure, and the cooperation between the guide wheel and the air guide rail is affected is improved.

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 aerial transport vehicle in an automatic material handling system. Background technique [0002] In the application of semiconductor automation factories, the aerial transport vehicle in the automatic material handling system (AMHS, Automatic Material Handling System, also known as the crane system) needs to transport the target object from one place to the designated position as required. If the position of the round box and the target delivery position are not on the same track, the transport vehicle needs to change the track to walk. At this time, the rotating electromagnet in the steering drive mechanism on the transport vehicle moves the guide wheel on the slide rail to the designated position and Under the interference of the upper guide rail, the walking track of the transport vehicle is change...
