Objective The automatic dispensing medicine module which is the key unit in traditional Chinese medicine dispensing machine is designed and presented in the paper.The design is based on the problem that the present task in dispensing traditional Chinese medicine is heavy and ineffective, and provides the foundation for the study of traditional Chinese medicine dispensing device.Methods The module is composed of dispensing system and weighting system, the control units of which are MSP430F2132.The operational principles are transmission by belt driving and weighting by weight sensor.Precision control of medicine dose is accomplished by the communication of the two systems.Results The prototype module has been accomplished.Conclusions The design is practicable and effective, and provides the basis for the further development of traditional Chinese medicine dispensing system.
