Abstract


Pharmaceutical tablets lack of grain is in dispensing , charging a link occurs on the packaging errors. With the GMP (Good Manufacturing Practices for Drugs) standard in Chinese pharmaceutical companies in -depth implementation , it has been recognized that the quality of medicines in order to ensure foolproof , the entire production process must be controlled . Pharmaceutical packaging equipment line detection is bound to be referred to an important aspect of the research and implementation . How to pharmaceutical preparations bottle packaging process, the lack of grain pills online testing errors of this kind , and make the appropriate disposition of this paper is to discuss the main issues . This non-contact optical detection as the study of the basic ideas . According to pharmaceutical tablet packaging equipment used in the actual situation , this paper for non -contact optical detection device to use optical , institutions and control of the three complementary functional parts are carried out targeted design and discussion. Part of the optical design , the paper mainly describes the control and the optical path of the optical signal received . At the institutional design part , the paper according to the actual work situation and pharmaceutical research laboratory conditions , design a detection module / combination of the mechanical organization and joined the trim on the module , locking mechanism for the pharmaceutical commissioning and use of convenient. Control part of the design to microcontroller core , considering the entire pharmaceutical packaging sectors , set up a synchronization signal generation, lack of grain signal detection, the processing operation produces the timing between , and ultimately design a practical control system . In theory , based on the design , the paper also some validation experiments are discussed. Based on the experimental data , this paper compares the various surface reflectance data to prove the design concept used in this paper as practicable ; article also actual production inspection system carried out similar work environment simulation laboratory testing, collected the actual lack of tablets error signal. After a certain period of use, but also the detection system pharmaceutical client to make a good evaluation .
