Abstract

The invention discloses an accurate assembling machine and method for a pre-filling type needle tube push rod. The accurate assembling machine comprises a rotary table, wherein the rotary table comprises an upper round plate and a middle round plate, which are coaxially arranged from top to bottom; a plurality of U-shaped needle tube placement holes with outward openings are uniformly formed in the periphery of the middle round plate; the upper round plate is provided with a push rod bayonet; a pair of supporting rollers are correspondingly arranged at inner sides below the U-shaped needle tube placement holes; the axes of the supporting rollers are parallel to a rotary shaft of the rotary table; a pre-twisting friction block is arranged at the outer side of the rotary table; a circular-arc-shaped notch which is coaxial with the rotary table is formed in the inner side of the pre-twisting friction block; a fine twisting depended wheel is arranged at the rear side of the pre-twisting friction block; and a fine twisting depended wheel driving mechanism, connected with the fine twisting depended wheel, is arranged below the fine twisting depended wheel. According to the accurate assembling machine and method disclosed by the invention, the pre-twisting friction block is adopted and the push rod is pre-tightened greatly, and tight twisting is carried out by adopting the fine twisting depended wheel, so that the push rod and an elastic rubber plug are connected in place; and leakage of injection liquid in a utilization process is prevented, the assembling quality and productivity of the push rod are improved and the assembling cost of the push rod 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...
