Development of a Multi-Variety Automatic Packaging System for Medical Test Boards
To meet the precision and rapid requirements of the heat sealing equipment for irregular medical test boards,a multi-variety,high-precision,and efficient heat sealing packaging control system was developed.The packaging machine's process flow and control requirements were analyzed.The RBF-PID temperature control algorithm was adopted to improve the heat seal-ing effect and efficiency.The machine vision system was used to acquire feature data of pre-made bags,and 47 types of irregular test board detection were achieved through image processing.Based on the Omron NJ series motion control PLC and two industri-al Ethernet control methods,the system's hardware and software design were carried out.The motion processes of feeding,bag-ging,heat sealing,detection,and unloading were improved and optimized.The HMI was developed to visualize the device and production status.After equipment commissioning and validation,the system operated stably in high-temperature and vibration working environments,with an average packaging speed of up to 1806 pieces per hour,an average qualification rate of 98.1％,and an average temperature error of only±0.8 8 ℃.Its reliability and accuracy were significantly improved.
