With the continuous optimization of Surface Mounted Technology (SMT) and the rapid development of the manufacturing process of surface mount components, the application of pick-and-place machines in the electronics manufacturing industry is becoming increasingly prominent. The CM402 high-speed pick-and-place machine is developed and produced by Panasonic in Japan, designed for batch processing of certain specific workpieces according to specific procedures. Based on a two-week on-site investigation and verification by the author, it was found that during the production process of splicing materials, if the detection of splicing materials stops, the time taken for cleaning up after the machine stops will affect production efficiency. By carefully analyzing the process flow of this equipment and reading its user manual, the detection of splicing materials and the stop-and-clean program can be technically transformed, and the Timer in the original electronic control system can be replaced with the PVS control system, enabling the function of continuous material reception without stopping the machine, thereby improving production efficiency.
This article takes the use of the PIC16F628 microcontroller to form a PVS control system as an example, starting from hardware system design and software system design, providing the printed circuit board diagram, circuit schematic, and source code.
Hardware System Design
The PVS control system is centered around the PIC16F628 microcontroller, consisting of the PIC16F628 microcontroller and its peripheral components, power module, and relay module. The printed circuit board and circuit schematic are shown in Figure 1 and Figure 2.
