| | | As the prefered brand of sensors worldwide, Banner knows the challenges of the factory floor. That's why we designed our line of PresencePLUS® vision detection from the ground up, with advanced features, easier setup and operation, rugged design, the most value of any vision devices in the market and, most of all, Banner reliability and support. A complete solution. From a single inspection point to plant-wide vision integration, Banner offers complete vision solutions. Vision sensing has two major elements: hardware—the camera, controller, lighting and brackets; and software— the control system, graphical user interface and image algorithms. Banner provides all of the elements to successfully deploy vision sensing in your facility. Visual Inspection Process 1. Acquire an image of the part. 2. Analyze the image. 3. Determine if the inspection passes or fails, and report the results to the manufacturing line. The part then either passes to the next process or is rejected and removed. | | |
| | | 1. Sensor: The sensor contains the imager, microprocessor and I/O. The imager has an array of tiny light-sensitive cells (pixels) that convert the target into an image. The microprocessor analyzes the image and makes determinations about it based on user-determined tolerances and criteria. The sensor exports the inspection results through some type of I/O, such as discrete, Ethernet or serial. 2. Lens:The lens focuses the light onto the sensor's imager. To determine the lens focal length for an applications, specify the field of view and working distance. HorizontE FO 3. Light Source: The light source is a critical component of any vision inspection unit. Lighting is the most powerful tool for creating contrast to amplify F0V the feature of interest, while minimizing other features of the part. Selecting the best light source depends on the shape, surface texture, color and opacity of the part. | | |
