Zohar Kantor explains how autonomous machine vision (AMV) has overcome these challenges<\/strong><\/p>\n\n\n\n<p>Traditionally, plastic injection moulding is a difficult application for machine vision. The highly reflective surface of plastics is hard to illuminate correctly, and the fact that the same production line can create items of different colours and shapes is problematic for traditional solutions, only capable of inspecting one product at a time.&nbsp;<\/p>\n\n\n\n<p>Autonomous machine vision (AMV) is a new approach to quality assurance (QA) developed by Inspekto, a German company with Israeli DNA.&nbsp;<\/p>\n\n\n\n<p>As the name suggests, this technology is conceived to be autonomous in every way, from determining the ideal number of samples the system needs to learn the characteristics of the item, to self-adjusting the camera settings to obtain the best image possible of the item to be inspected. This allows production line engineers with no previous knowledge of machine vision or artificial intelligence, to set up the system to work in hours, rather than weeks and months with the aid of a systems integrator. &nbsp;<\/p>\n\n\n\n<p>Thanks to its self-adjusting and self-learning capabilities, the INSPEKTO S70, the first QA system in the AMV category, can successfully overcome the challenges that make traditional QA solutions inadequate for plastics injection moulding. Here are three examples of how AMV can benefit this industry. &nbsp;<\/p>\n\n\n\n<p><strong>Multi-product inspection<\/strong><\/p>\n\n\n\n<p>Traditional machine vision solutions are designed to inspect only one item at a specific point on the production line. This makes them unpractical for a sector such as plastic injection moulding, where the same production line can potentially make various products that come in varying shapes and forms.&nbsp;<\/p>\n\n\n\n<p>However, Inspekto TYPES, one of the many apps that can be installed on the S70, allows plastics manufacturers to overcome this issue. <\/p>\n\n\n\n<p>While traditional machine vision solutions can only monitor one product at any given location on the production line, an S70 system installed with TYPES\u2122 is able to inspect any number of products \u2014 even tens or hundreds of different products \u2014 at that same location on the line.&nbsp;<\/p>\n\n\n\n<p>Emerging from the traditional constraints of one-product-per-solution, AMV allows manufacturers to inspect a variety of items with one single system, something that was unthinkable until recently.&nbsp;<\/p>\n\n\n\n<p><strong>Self-adjusting camera parameters<\/strong><\/p>\n\n\n\n<p>Another typical problem in this sector is achieving the correct lighting of the parts to be inspected. Typically, injection moulds have smooth, highly reflective surfaces that resemble mirrors.&nbsp;<\/p>\n\n\n\n<p>Additionally, moulds can be the same colour of the plastic polymer, or can appear that way because of a lack of contrast due to insufficient illumination of the inside of the mould.&nbsp;<\/p>\n\n\n\n<p>Finally, moulding machines are built to be as compact as possible, so that they will open just enough to eject the part, but not enough to guarantee adequate illumination for visual QA.&nbsp;<\/p>\n\n\n\n<p>All these challenges make inspection hard for traditional QA solutions, but not for AMV systems, which are designed to self-adjust their camera parameters to obtain perfect lighting, focus and contrast. <\/p>\n\n\n\n<p>In this way, the plastic parts can be illuminated in a way that clearly differentiates one from the other, allowing the system to perform effective visual QA in total autonomy.<\/p>\n\n\n\n<p><strong>Total QA<\/strong><\/p>\n\n\n\n<p>Traditional QA solutions require several months to be designed, built and tested, and the whole process costs often reach even hundreds of thousands of euros.&nbsp;<\/p>\n\n\n\n<p>On the other hand, the INSPEKTO S70 can be installed in by the plant\u2019s own line engineers, without any external intervention, and costs a fraction of a traditional solution.<\/p>\n\n\n\n<p>The cost-effectiveness and rapidity of installation of the S70 mean that plant managers can have a QA station at every junction on the production line, instead of just at the end \u2013 reaching far higher productivity, profitability and yield.&nbsp;<\/p>\n\n\n\n<p>Alternatively, QA managers can decide to move their S70 from one junction to the other when needed, by just repeating the quick and easy installation process.&nbsp;<\/p>\n\n\n\n<p>In this way, manufacturers can achieve what Inspekto calls Total QA \u2013 quality assurance at every step of production.<\/p>\n\n\n\n<p>Zohar Kantor is VP Sales of <strong><a href=\"https:\/\/www.inspekto.com\/\">Inspekto<\/a><\/strong>. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Plastic injection can be a tricky application for traditional machine vision solutions.
