Choosing the Right Vision System to Meet Your Quality Assurance Needs

Quality control is one of the most important stages of the manufacturing process. A product's packaging is the final chance to persuade a consumer that a product is worth buying. By inspecting one hundred percent of products on high-speed packaging lines, automated vision inspection can play a key role in preventing poor-quality products ending up on retailer shelves. But despite this, a staggering 90% of vision system implementations fail to exceed or even meet users' expectations¹.

A new white paper 'Selecting an Effective Vision System For Quality Assurance Applications' begins by revealing the reasons behind this high failure rate. The paper goes on to explain that vision inspection is capable of much more than just code verification. Systems can prevent mislabeling, detect printer errors, spot damage to packaging and verify the integrity of product seals. Consequently, the technology can be enormously beneficial to a manufacturer's quality control program, but only if an informed decision is made.  

To select a vision system which best fits their quality assurance requirements, manufacturers are advised to:

  1. Evaluate their needs
  2. Select a system type, and
  3. Select an appropriate provider

1.    Evaluate Needs

The paper, which can be downloaded for free, warns readers against rushing to buy and install equipment without first evaluating their production environment and quality control requirements. Consideration should be given to the space available and the location on the production line, environmental factors such as line speed, vibration, lighting and product handling solutions, as well as the design and shape of product packaging.

2.    Select a System Type

Once manufacturers have a thorough understanding of their particular needs, it's time to evaluate the type of system required. Vision systems are separated into two types:

  • Custom solutions which cover everything from smart camera kits and a few brackets to sophisticated PC-controlled systems, and
  • Standard solutions which are mass-produced by a vision provider and feature a unified design and interface.

The paper discusses the pros and cons of each system, along with typical applications.

3.    Select an Appropriate Provider

Once a decision has been made regarding the best solution, manufacturers must decide which vision provider to use. This comes down to selecting a local integrator or working with a larger organisation. The paper concludes by highlighting the benefits and drawbacks of both options, as well as the importance of constant communication between the vision system supplier and manufacturer to ensure a successful vision inspection program.
