Using Smart Camera Automation
Metal part inspection is one of HNJ’s core competencies. One example of a metal part inspection application was to inspect a deep-drawn metal part. The part was made with a progressive die stamping process.
The Problem:
Our customer needed quality control to inspect the sleeves. The sleeve insertion needed in-line quality control, to ensure acceptable sleeve length. Before we started, it was clear that batch testing wasn’t good enough. Batch testing only looked at a few samples at a time, which was missed defects throughout the production line. As a result, we had to figure out a way to detect these errors.
HNJ Solution:
To maximize quality control, we designed a system to check the metallic sleeves. In this case, we inspected the sleeve insertion measurements, using our smart camera inspection system. Our solution checks for defects on every unit being produced. This reduced many of the defects passing the old inspection, and increased quality for our customer.
Capabilities:
HNJ metal part inspections apply to a wide range of metal inspections. For example, some of these include:
- Progressive Stamping Inspection
- Precision Stamping Inspection
- Production Machining Inspection
- Tool & Die Inspection
- Assembly Inspection
- Tray-Based Inspection
Tray-Based Inspection
Also, HNJ has developed solutions to inspect a series of metal parts:
Above is an example of a table-top solution developed by HNJ for tray-based inspections. This machine vision solution inspects a series of metal parts sitting in the tray, moving to each part and checking each for defects, one at a time. If we find one or more defects, they’re noted “NG” or “not good” and the image shows exactly which one was defective. The image captured by the HNJ Solution also shows where the defect was found and highlights the failed part.
