Abstract

The invention discloses a pre-filled needle tube push rod precision assembly machine and an assembly method thereof, comprising a turntable, the turntable includes an upper circular plate and a middle circular plate arranged coaxially from top to bottom, and a plurality of There is a U-shaped needle tube opening with an outward opening, a push rod bayonet on the upper circular plate, and a pair of rollers corresponding to the inner side of the U-shaped needle tube placement port; the axes of the rollers are parallel to the rotation axis of the turntable; Pre-twisted friction block, the inner side of the pre-twisted friction block is provided with an arc notch coaxial with the turntable, the rear side of the pre-twisted friction block is provided with a fine-twisted roller, and the fine-twisted roller is provided with a fine-twisted roller connected to the fine-twisted roller. Wheel drive mechanism. The present invention adopts the pre-twisted friction block and the push rod to be pre-tightened firstly, and then tightened tightly through the fine-twisted wheel, so that the push rod and the elastic rubber plug are connected in place, preventing the leakage of the injection during use. The assembly quality and production capacity of the push rod are improved, and the cost of the push rod assembly is reduced.

Description

technical field [0001] The invention relates to the technical field of assembly equipment for prefilled syringe push rods, in particular to a precise assembly machine for prefilled syringe push rods and an assembly method thereof. Background technique [0002] With the development of biomedical technology and the increasing requirements of medical personnel for the convenience, reliability, and safety of drugs, the use of prefilled syringes has shown a rapid increase in the world this year. For prefilled syringes The demand for assembly and packaging equipment has also increased. [0003] The benefits of prefilled syringes include accurate dosage, avoiding cross-contamination, simplifying the working procedures of frontline medical staff, and reducing the chance of accidents, etc. [0004] The basic structure of the prefilled syringe is as follows: figure 2 As shown, the production process includes: accurate filling of liquid medicine → sealing of rubber plugs → inspection...
