Abstract

The invention discloses a serial multi-shaft step control method and system used in solder paste printing machine. The invention cooperative controls plural key moving shafts for solder paste printing by plural working conditions of the solder paste printing machine such as initialization, waiting, automatic print, quit, configuration and so on. A DC 4-axis step servo driver in the system drives X-axis stepper motor and scraper Z1-axis stepper motor and scraper Z2-axis stepper motor of camera; a DC 4-axis step servo driver drives platform Y1-axis stepper motor, platform Y2-axis stepper motor, platform X-axis stepper motor and wide rail axis stepper motor; An AC single axis step servo driver drives camera Y-axis stepper motor. The invention can effectively improve cooperative control capacity and alignment accuracy for PCB solder paste printing machine, has less wiring, and high resistance to electromagnetic interference, compact structure and abounding control functions, and is applicable for various PCB solder paste printing machine.

Description

technical field [0001] The invention relates to the field of PCB board solder paste printing machine control systems, in particular to a serial multi-axis stepping control system used for solder paste printing machines and using a stepping servo instruction VI library following the LabVIEW technical standard. Background technique [0002] PCB solder paste printing machine is an important electronic manufacturing equipment in the SMT process. The PCB assembly process generally includes six processes: PCB solder paste printing, post-printing optical inspection, placement, post-mount optical inspection, reflow soldering or wave soldering, and post-soldering optical inspection. Solder paste printing is the first process of the SMT process, and its printing accuracy is directly related to the placement and soldering quality. Poor printing quality may lead to bad conditions such as false soldering on the PCB. PCB solder paste printing generally includes manual, semi-automatic, an...
