Case studies of vision systems in the electronic devices industry. As electronics such as smartphones, gaming consoles, and PC's become smaller and thinner, their semiconductors and other electronic components need to be even more compact and accurate. Additionally, 3D vision systems bring ultimate stability to these inspections to identify height changes despite low contrast in materials.
Case studies of vision systems in the resin and container industries. Vision systems are used in the molding and resin industries to automate inspections and ensure defective products are not released.
These inspections are necessary to detect any mishaps in processes such as injection molding, plastic forming, laminations, and product labeling. A color camera is generally preferred when inspecting for changes or irregularities in color. Each pixel of a color image holds RGB information, which is three times the data of a monochrome pixel.
Because there is more data per pixel, extraction and differentiation easier. Monochrome cameras are preferred for measurement type inspections, where strong edge extraction is needed. Monochrome cameras are also commonly paired with colored lighting to aid in inspection. Examples include mitigating ambient light, causing a UV-dyed material to fluoresce, and emphasizing surface scratches.
Traditionally, colored lighting is paired with a monochrome camera, and the color wavelength of light will vary depending on the desired inspection.
Colors which closely match a given target or are complementary to the target color can strategically manipulate and stabilize the image. To differentiate subtle differences in surface characteristics and further stabilize inspections, an intelligent lighting method called Multi-Spectrum uses eight different colors of light to gather more pixel data per pixel.
Having data from multiple wavelengths creates more contrast between like-colors, and a true color image can be shown on the operation screen despite using a monochrome camera. Yes, it is possible! The 4-directional pattern projection lighting allows the XT to gather 3D data of complicated geometry without blind spots.
Sophisticated inspection algorithms, such as the defect tool, can detect localized changes in contrast to identify scratches and stains. Because the inspection looks for localized changes, external influences like ambient light do not disrupt the inspection.
In addition to robust inspection tools, 24 image enhancement filters are available to reduce the effects of uneven lighting, rough surfaces, or variation among products. Two noteworthy filters are the scratch defect extraction, which enhances linear flaws on rough targets, and the shading correction, which emphasizes sharp changes in contrast while eliminating gradual ones. Stable detection of burrs and chips relies on the accuracy of edge extraction.
KEYENCE vision systems include profile defect tools, which precisely extract lines, circles, ovals, and free form curves to detect any sections which stray too far from the expected shape. The user can specify thresholds to control the size and severity of considered flaws. All KEYENCE vision systems include a wide range of measurement and dimension tools, which make finding intersections, midpoints, and distances very simple.
For example, simply click anywhere along an edge to auto-extract that line, or refer to line results from a tool which has already been configured. This intuitive interface allows users to easily create complex inspection settings while combining several measurements and dimensions. When using a vision system, the hardware will be selected based on the application specifications and desired inspection details.
This section outlines how to select the best camera, lens, lighting, controller, and any other accessories needed. Area cameras are categorized into four main groups: high-resolution models, high-speed models, standard models, and compact models. Each model has the ability to be color or monochrome. The correct camera is dependent on the application, which is outlined below.
When choosing the right lens for the vision system, there are a variety of factors to consider. Both the field of view FOV and working distance WD of the inspection will determine the right lens focal distance for image capture.
The depth of field range of the depth of focus and contrast are other important considerations when selecting a lens. A general selection procedure is outlined below. Accept All Cookies.
