Aiming at the deficiency of the control system and operating platform of domestic dispenser, as well as the problems of colloidal accumulation and uneven dispensing in traditional peristaltic dispenser,a complementary movement relationship between the peristaltic pump and the dispensing head was proposed by analyzing the relationship between the pump haracteristics and the flow of the peristaltic pump. Based on this, a control system of threeaxis linkage peristaltic dispenser with touch screen as manmachine operation platform and independent motion controller as CNC core was designed. The test shows that the control system can greatly improve the dispensing accuracy.
