Method and device for generating master-salve servo system synchronous signals, and lamp detector

Abstract

The invention discloses a method and a device for generating master-salve servo system synchronous signals, and a lamp detector. The method for generating the master-salve servo system synchronous signals comprises the following steps that: a master servo system and a slave servo system receive control information sent by a virtual main shaft respectively; the master servo system and the slave servo system track the virtual main shaft according to the control information, and generate a master position following error and a slave position following error respectively; a judging module judges whether the master position following error and the slave position following error are in accordance with a predetermined condition; when the master position following error and the slave position following error are in accordance with the predetermined condition, a synchronous signal generating module generates the synchronous signals. By the invention, the position errors between the master and slave servo systems are small; the master and slave servo systems are synchronized; and the false inspection rate of the lamp detector is reduced.

Description

technical field [0001] The invention relates to the field of pharmaceutical equipment, in particular to a master-slave servo system synchronization signal generation method, device and light inspection machine. Background technique [0002] The light inspection machine is a machine for inspecting white spots, black spots, desquamation, fibers, hair, flocs and other particles of liquid preparations through a visual system. It is an important quality inspection equipment in the pharmaceutical industry. It mainly includes master servo system, slave servo system, industrial camera, industrial computer and rejecting mechanism. When the bottle containing the liquid preparation enters the theoretical synchronization area of ​​the master-slave servo system through the bottle-feeding track, the main turntable driven by the main servo motor, the bottle rotating mechanism, and the bottle body brake mechanism, the synchronization signal generating device gives a master-slave servo syste...
