High speed, high resolution inline smart 3D inspection
11 Jan 2019
The Gocator family of 3D measurement sensors is characterized by its on-board 3D processing and measurement capabilities. This means that no additional controllers or PCs are require to produce 3D measurements. In addition the new Gocators are housed in ultra-compact, IP67-rated cases to allow them to be mounted in small spaces.
High speed inspection of moving parts
The Gocator 2500 series is designed for high-performance inspection of small parts such as electronics components. A new custom high-speed 3 megapixel imager and megapixel lens provide micron-level X and Z resolution at significantly increased production speeds up to 10 kHz. Completely self-contained, the Gocator 2500 series feature a blue laser and advanced optics to deliver superior data quality on the challenging shiny/specular surfaces that are common in consumer electronics inspection applications.
Dedicated FPGA processing with built-in measurement tools for 3D alignment, part segmentation, and 3D feature extraction allow Gocator 2500 sensors to handle the complete processing pipeline—from raw image data to 3D result and pass/fail control.
Complete 3D inspection in a single snapshot
The combination of market-leading 6 µm XY resolution and 0.2 µm Z repeatability makes the Gocator® 3504 3D stereo camera snapshot sensor ideal for precise sub-micron inspection of small parts. Pre-calibrated and ready to measure out-of-the-box, it is ideal for inline applications where objects are momentarily stationary such as robotic inspection and pick-and-place. Since the imaging takes place when the object is stationary, snapshot sensors remove the need for a motion stage and avoid errors due to vibration.
The unit includes next-generation dual-core controllers, which significantly increase onboard processing speed to match inline production speed. It has a measurement range = 8 mm and a field of view of 12.5 x 14.6 - 13.4 x 14.7 mm. However a 3D stitching capability allows automatic stitching of 3D data from multiple scans into a single 3D scan for high resolution over an even wider field of view.
The Gocator 3504 sensor is designed for high precision surface and geometry inspection. The stereo camera approach reduces data loss due to surface occlusions, which could block projected light or the camera’s view in a single camera configuration. It can be used in a wide range of electronics and medical applications such as connector and pin coplanarity, wire detection, surface flatness and stent inspection.
The plug-and-play functionality of GoMax allows the quick and easy addition of this massive data processing power to any Gocator sensor or multi-sensor network. GoMax® features a distributed design based on peer-to-peer networking that allows engineers to easily accelerate entire multi-sensor networks. In this way multiple Gocator® sensors can be simultaneously accelerated and multiple GoMax® units can be easily added to meet specific inspection needs.
