Product Description

Blood collection needle assembly machine

Technical Information

1.Introduce

The product range is from 18G to 34G. In order to improve the assembly quality of the needles, TOPKEY has an original mechanical structure and high-quality machined parts. The original visual inspection technology detects 100% of the smallest defects in the tip of the needle and also detects blockages in the 34G holes. The entire assembly process is monitored by sensors and vision inspection systems, and various production data can be statistically analyzed on the HMI.

TOPKEY Automation can also produce "assembly machines for all kinds of needles".

3.Needle Vision Inspection System

Needle vision inspection capability

We have done secondary development on the KEYENCE XG vision system platform for defect detection of needles with a completely original vision algorithm, and it has passed the test of long-term operation and various challenging experiments.

KEYENCE

KEYENCE has the industry's fastest vision inspection system, powerful inspection capabilities and secondary development platform.

4.Needle Tip Vision Inspection System

The Needle Tip Vision Inspection System, which has been in operation at N Company's factory for more than a decade, is stable and reliable and is capable of identifying 100% of needle tip defects. Defects are recognised by detecting the shape of the needle tip and even small defects can be detected.

Vision inspection software has running lights, data statistics classification and other functions for easy viewing.

6.Needle Blocking Inspection System

High-precision detection of needle blockage

For extremely fine diameter pen needles, we have developed the industry's highest precision pen needle blocking detection system, which is capable of detecting 100% of blocking defects.

After the pen needles are completely sealed above and below, the blocking is detected by regulated precision pressure, using the industry's highest precision pressure sensors for one-to-one detection of the pen needles.
