Full-automatic blood taking needle assembly machine

Abstract

The invention discloses a full-automatic blood taking needle assembly machine. The full-automatic blood taking needle assembly machine comprises a sample disk, a supporting frame and a spring assembly workpiece. The sample disk conveys needle cores to be assembled to the working position of the spring assembly workpiece. The spring assembly workpiece comprises a first vibrating disk, a second vibrating disk and a power assembly. The first vibrating disk contains front springs. The second vibrating disk contains rear springs. The first vibrating disk and the second vibrating disk can sort the front springs and the rear springs in order and output the front springs and the rear springs. The power assembly drives blood taking needle cores to move to enable the front springs and the rear springs to be assembled onto the needle cores. The spring assembly workpiece is accurate in positioning. The front springs and the rear springs are accurately mounted on the needle cores in one working position. The efficiency is high, and the stability is good. The whole full-automatic blood taking needle assembly machine is more compact in structure.

Description

technical field [0001] The present invention relates to a fully automatic assembling device for a blood collection needle, more specifically to a workpiece used for assembling a front spring and a rear spring on a needle core in a fully automatic assembly machine for a blood collection needle. Background technique [0002] Blood collection needles are an important tool for blood testing in clinical laboratories. With the improvement of medical standards and people's increasing requirements for the comfort of medical devices, new blood collection needles on the market now mostly use mechanical devices, and the needles use ejection devices, which can almost It is completely accurate, fast, moderate in depth, and straight-line path pierces the skin, and the needle can automatically rebound into the shell after blood collection, which greatly reduces the pain of the patient. Due to the complex structure of the new blood collection needles, small accessories, high production proc...

AI Technical Summary

Problems solved by technology

Since the third-generation blood collection needle is composed of jacket, slider, front spring, needle core, rear spring, front cover and other parts, the internal structure is complex and the parts have various shapes. In order to improve production efficiency, reduce labor costs and reduce product defects In view of the fact that each component is different and it is a special-shaped workpiece, it is necessary to design the positioning direction and feeding direction of each part. Each part needs a suitable positioning guide to be assembled smoothly. The spring is a flexible part. The characteristic is that it is easily deformed by external force, and it is easy to be entangled and difficult to separate. For the complete assembly of the whole blood collection needle, the assembly machine needs to automatically complete the whole process of spring parts from feeding to assembly. The blood collection needle in the prior art Fully automatic assembly equipment cannot accurately install the front spring and rear spring on the blood collection needle core
