A method and system for controlling multi-station pick-up of die-casting machine based on PLC

Abstract

The invention relates to a PLC-based multi-station pick-up control method and system for a die-casting machine. The method is specifically: PLC periodically detects the working status of each station, generates a corresponding BOOL amount, and writes all BOOL amounts into words section and send the byte to the pick-up robot. The stations include sawing station, trimming station and marking station. The working status includes the status of the workpiece and the completion status of the station. The working status of the station, and detect the station that the workpiece has passed. When any one station is vacant, the pick-up robot will transfer the workpieces that have been processed on other stations and have not passed the vacant station to the vacant station. Compared with the prior art, the present invention has the advantages of less calculation amount and high efficiency.

Description

technical field [0001] The invention relates to the field of workshop machine tool control, in particular to a PLC-based multi-station pick-up control method and system for a die-casting machine. Background technique [0002] At present, most workshops have realized the automation of the die-casting process. At present, the processing procedures of die-casting workpieces are fixed, followed by die-casting, taking out, sawing, trimming, marking, and placing the output position. The output position is the last process. Die-casting machines Under the action of pressure, the molten metal is hydraulically injected into the mold for cooling and forming. After the mold is opened, solid metal castings can be obtained. At present, the process flow is fixed in the production process. The die-casting machine is used as the master station, and other peripheral equipment is used as the slave station. The pick-up robot transfers the workpiece, and many processing procedures are involved i...

[0002] At present, most workshops have realized the automation of the die-casting process. At present, the processing procedures of die-casting workpieces are fixed, followed by die-casting, taking out, sawing, trimming, marking, and placing the output position. The output position is the last process. Die-casting machines Under the action of pressure, the molten metal is hydraulically injected into the mold for cooling and forming. After the mold is opened, solid metal castings can be obtained. At present, the process flow is fixed in the production process. The die-casting machine is used as the master station, and other peripheral equipment is used as the slave station. The pick-up robot transfers the workpiece, and many processing procedures are involved in the automated production process. Once a certain process is abnormally processed, the entire production process will be terminated. At the same time, the pick-up robot also grabs the workpiece according to a fixed process, resulting in greatly reduced production efficiency. If one of the equipment fails during the process, the entire production process will be suspended
