Control system for blood taking needle assembly machine

Abstract

The invention discloses a control system for a blood taking needle assembly machine. The control system comprises a detecting mechanism, an assembling mechanism, an index plate feeding mechanism, a mechanical arm mechanism and an upper computer. The index plate feeding mechanism, the mechanical arm mechanism, an outer sleeve feeding mechanism, an inner sleeve feeding mechanism, a front spring feeding mechanism, a rear spring feeding mechanism, a rear cover feeding mechanism and a front cover feeding mechanism are internally provided with PLCs correspondingly, and the PLCs are in network communication connection with control modules in the upper computer correspondingly. According to the control system, the seven parts are automatically assembled according to different sequences, the PLC microcomputer control technology is adopted, each functional unit uses an independent control system, and connection between the PLCs of the functional units and connection between the PLCs and the upper computer are realized through the PLC network communication function modules. The control system has the advantages of being high in degree of automation, accurate in process control, convenient to operate, stable in operation and high in product percent of pass.

Description

technical field [0001] The invention relates to an automatic assembly machine system, and more particularly to a control system of a blood collection needle assembly machine. Background technique [0002] With the development of economy and the improvement of living standards, humanistic care for patients has become a more and more concerned issue in the medical field. Therefore, the blood collection process should have the characteristics of fast, safe, small wound and low pain. To meet the above needs, a new generation of blood collection needles came into being. The small needles can also reduce the psychological pressure of patients. It is composed of 7 parts including outer jacket, inner jacket, front spring, needle core, rear spring, rear cover and front cover. It reduces the pain of the patient, but the internal structure is complex, and the parts have various shapes and small volumes, and the production process requirements are high. In order to improve production e...

Therefore, the blood collection process should have the characteristics of fast, safe, small wound, and low pain. In order to meet the above needs, a new generation of blood collection needles came into being. The small needles can also reduce the psychological pressure of patients; the internal structure of the new generation of blood collection needles is complex, It is composed of 7 parts such as the jacket, the inner jacket, the front spring, the needle core, the rear spring, the back cover, and the front cover. It reduces the pain of the patient, but the internal structure is complex, and the parts have various shapes, small volume, and high production process requirements. In order to improve production efficiency, reduce labor costs, and reduce the defective rate of products, it is necessary to design the positioning of each part. Direction and feeding direction, each part needs proper positioning and guidance to be assembled smoothly. If the needle tip is placed upside down, no needle, short needle or partial needle, etc., the produced blood collection needle is unqualified, and such product Putting it into the market will cause safety hazards to users, and even medical accidents may occur. It is difficult to guarantee product quality with manual and simple automatic production equipment, so now the production of blood collection needles starts to use fully automatic closed production equipment, so that It can effectively improve production efficiency and product quality. Fully automatic equipment can work around the clock without fatigue. It has the consistency and repeatability that manual production does not have. It avoids defective products caused by human misoperation and greatly reduces The labor intensity of workers is also of great significance for changing production methods and improving production efficiency, but there is no highly automated automatic assembly machine for blood collection needles in the prior art
