AI Technical Summary

Technical Problem

Existing needle sorting equipment tends to get stuck together when separating needles of different lengths, resulting in poor separation efficiency. Furthermore, it can only separate two batches of needles at a time, leading to low separation efficiency.

Method used

By setting up a conveying device for fixed-distance transport, combined with an alignment device, a measuring device, and an ejection device, the fixed-distance transport of needles and the sequential separation of needles of various lengths are achieved. Permanent magnetic materials are used to increase the friction between the needles and the conveyor belt. A laser transceiver is used to measure the length of the needles, and the needles are sorted by the ejection device and the collection device.

Benefits of technology

It effectively prevents needles from getting stuck together, improves the separation effect, and increases the separation efficiency of needles of various lengths.
