Automatic feeding device for blood return tube of disposable infusion set

Abstract

The invention discloses an automatic feeding device for a blood return tube of a disposable infusion set. The automatic feeding device comprises a vibration feeder, wherein the vibration feeder is provided with a single track, and an outlet end of the track is connected with an inlet of a blood return tube separation feedback mechanism; a push plate is arranged above the blood return tube separation feedback mechanism, and is connected with a piston rod of a double-rod cylinder; the blood return tube separation feedback mechanism comprises a distribution manifold, and the two sides of the top of the distribution manifold are respectively and movably provided with a striker plate; the distribution manifold is provided with a plurality of blood return tube accommodating channels; and the bottom of each blood return tube accommodating channel of the distribution manifold is connected with one end of a delivery duct, and the other end of the delivery duct is connected with a blood return tube positioning fixture. The automatic feeding device can realize the automatic remote feeding of the blood return tube and other soft parts in the automatic assembling equipment for disposable infusion set products, the conveying distance can reach 5meters, vertical conveying can be realized, and the automatic feeding device has a simple structure; and a plurality of parts can be conveyed simultaneously, so the production efficiency is greatly increased, and the automation degree is improved.

Description

technical field [0001] The invention relates to an automatic assembly device for a disposable infusion set, in particular to an automatic feeding device for returning blood vessels of a disposable infusion set. Background technique [0002] The disposable infusion set is composed of more than a dozen parts and components such as a filter assembly, a long catheter, a regulator assembly, a drip funnel assembly, a short catheter, and a bottle insertion needle assembly. It also includes soft parts such as return blood vessels and catheters. The process is complex. [0003] In the existing automatic assembly equipment for disposable infusion sets, the automatic feeding of parts to be assembled generally adopts a combination of a vibrating disc feeder and a linear vibrating feeder. In the vertical assembly system of disposable infusion sets, the return blood vessel is assembled at a height of nearly 2 meters above the equipment. The structure of the feeding system is very complic...

AI Technical Summary

Problems solved by technology

In the vertical assembly system of disposable infusion sets, the return blood vessel is assembled at a height of nearly 2 meters above the equipment. The structure of the feeding system is very complicated, the equipment is also very large, and the position of the feeding interface with the assembly device is also difficult to arrange. , and because the return blood vessel is a soft and elastic material, its feeding and assembly positioning are very difficult
