High resolution intelligent 3D line profilers for electronics inspection
11 May 2018
The Gocator 2410 and Gocator 2420 intelligent 3D line profile sensors from LMI Technologies offer industry-leading resolution capabilities. Featuring 2 megapixel sensors and a new embedded processor, they allow the measurement of micron level features at high speed over a large field of view.
Designed to meet the growing need for 3D inspection of high volumes of small parts at high speed in the consumer electronics industries, these Gocators feature a blue laser to create the line profiles for 3D measurement. This produces ‘cleaner’ data and highly reliable results even on challenging reflective or shiny surfaces. This is crucial for electronics and small part feature recognition, especially for the inspection of materials such as glass and assemblies requiring glue.
Fast production rates demand high-speed quality control, while parts with complex shapes require maximum scan coverage. The Gocator 2410 and Gocator 2410 operate at twice the speed of the Gocator 2300 Series, yet offer 50% larger fields of view compared to competitors. High precision measurements of small gaps and features are guaranteed with an industry-leading resolution of 6µm in the X direction with results repeatable to 0.2µm in height.
Inspection applications include:
Glue bead volume and uniformity
Cell phone glass/bezel gap and flush
Cell phone camera lens orientation
Solder paste height and positioning
Nano-SIM connector pin heights
Cell phone battery surface defects
Cell phone PCBs and parts
Logo height variations
In addition, Gocator laser profilers support seamless multi-sensor networking for scanning larger components and assemblies or complex parts , such as those with irregular surface geometry and multiple occlusions.
Precalibrated and completely self-contained, every Gocator 3D smart sensor is supplied with a built-in web-based browser user interface and powerful 3D measurement tools. This provides the flexibility to improve the quality and efficiency of factory production without the need for an external PC or additional software. The extensive measurement capabilities allow decision making to take place inside the sensor with the results communicated directly to a factory, reducing costs and saving time. For multi-model production lines, the sensors can be “reprogrammed” on-the-fly by loading different “job” files that correspond to each different model. The job file contains the specific settings for measurements, exposures, and pass/fail criteria.
The lightweight Gocator 2410 and 2420 have a small footprint and are supplied in a revised IP67 industrial housing. This makes them easy to fit into tight spaces or mount on robotic arms or be used in applications where multiple sensors need to be linked together. A Gigabit Ethernet interface and PLC connectivity makes integration into a factory environment very straightforward, reducing installation costs.
