Feed mechanism of needle base of assembling machine for medical accessories

Abstract

The invention provides a feed mechanism of a needle base of an assembling machine for medical accessories and belongs to the assembling device technical field for medical accessories. The feed mechanism of the needle base of the assembling machine for medical accessories solves the technical problem of the existing feed mechanism that the degree of automation is low. The feed mechanism comprises an installing shelf and a feeding orbit capable of transporting the needle base, the installing shelf is provided with a lifting base and a drive piece 1 capable of driving the lifting base for moving up and down, the lifting base is provided with a long strip-shaped installing base, a through hole is formed in the installing base, a material hanging plate is inserted in the through hole, a drive piece 2 capable of driving the material hanging plate for moving in the through hole in a reciprocating motion mode is fixedly arranged on the installing base, a material hanging notch capable of hanging the needle base is formed on the material hanging plate; the material hanging notch is connected with the outlet end of the feeding orbit in a butt joint mode; the installing base is provided with a material pressing plate located just above the material hanging notch. The column-shaped needle base is transported to the assembling carrier for executing the next process by material receiving, returning, dropping, material falling and material pressing steps, the operation is convenient and fast and the degree of automation is high.

Description

technical field [0001] The invention belongs to the technical field of assembly equipment for medical devices, and relates to an assembly equipment for a needle seat of an infusion set, in particular to a feeding mechanism for a needle seat of a medical accessories assembly machine. Background technique [0002] The infusion set is an auxiliary device commonly used in medical treatment, mainly used for intravenous infusion. It is an important disposable medical consumable that has undergone aseptic treatment and establishes a channel between the vein and the liquid medicine. It is generally composed of an intravenous needle, a protective cap, a liquid medicine filter, a flow rate regulator, a drip pot, a cork puncturer, and an air inlet pipe air filter connection. All components are connected through conduits, and the medicinal liquid flows through the conduits. In the manufacture of infusion sets, the venous needle is connected to the catheter of the infusion set through t...

AI Technical Summary

Problems solved by technology

[0004] The monolithic device provided in the above literature is mainly aimed at the assembly of winged needle hubs, and is not suitable for non-winged needle hubs. With the increase of different needs, many needle hubs of intravenous needles of infusion sets are without wings. When assembling the needle holder with the catheter or the venous needle, it is difficult to quickly and neatly load the ordinary cylindrical needle holder and realize the assembly with the catheter or the venous needle, and the degree of automation of the above-mentioned device is low
