Research And Development Of The Automatic Assembly System For IBS Radiopaque Marker

With the rapid development of Chinese medical industry, the application of automation technology in this field is becoming more and more extensive. However, the development of automation technology should be based on the guide of actual production in enterprises. In the medical industry, the highest risk is the third type of medical equipment, so the relevant laws on the quality of products have strict requirements. It is very important to improve the stability and quality of the product process. For this purpose, a research and development of the automatic assembly technology for the IBS(Iron-based Bioresorbable Scaffold) Radiopaque Marker were depicted.The design of principle scheme is the most important link in the design of the scheme. According to the design requirements of the assembly system, the structure of IBS Radiopaque Marker was analyzed. Based on the basic theory of design method, the design scheme of intermittent feeding, developing material shear, visual positioning and electric pressure riveting were determined. The assembly chart of the whole automatic process for the IBS Radiopaque Marker was proposed.Based on the automation process chart and combined with the actual situation, the layout of the mechanical structure of the automatic assembly system for the IBS Radiopaque Marker was determined. The mathematical model for the key of the motion platform has been established. The design of entire motion platform and table selection of sliding screw has been completed. According to the design principle of TOP-DOWN, the analysis and design of feeding mechanism, supporting mechanism and material picking mechanism have been finished. The overall design of the whole mechanical structure and the test of the physical assembly were completed.Analysis of common motion control method and the control scheme of PC+ motion control card was proposed. The analysis and selection of the actuator and sensor were completed, the hardware platform of the whole motion control system was built. The design and research of the peripheral circuit of the control system and the PID control algorithm were completed.
