OptiSure AOI add-ons provide optical assurance of fluid deposit accuracy and integrate with Nordson EFD’s proprietary DispenseMotion software. Using robots’ existing vision systems to verify fluid deposit widths and diameters, the AOI software determines if dispense requirements have been met. Constant closed-loop feedback provides automated quality control (QC) data, saving manufacturers time and cost.
“Optical assurance of fluid deposit accuracy in an off-the-shelf solution is a game changer for our customers,” said Johnathan Titone, global product line manager for automated dispensing systems, Nordson EFD. “We saw a need in the market to integrate automated dispensing and AOI and we’re pleased to provide a market-leading solution.”
When paired with the OptiSure confocal laser, the AOI software measures the height of a fluid deposit in addition to the width and diameter — providing 3D deposit verification. Instant feedback eliminates the need to purchase additional QC equipment while increasing customer confidence and trust.
In addition, the confocal laser detects deposit height measurements regardless of the transparency of the fluid, which can sometimes distort quality data.
According to Nordson, the user-friendly interface of the DispenseMotion software reduces operator training time – offering time savings when compared to standard AOI stations that require extensive training and programming.
Last August, Nordson EFD launched its GVPlus and PROX families of automated fluid dispensing products.
The new GVPlus automated fluid dispensing solution is said to offer improved repeatability, bigger payloads with simplified setup requirements, and superior vision capabilities. Repeatability is now at 8 μm, improving repeatability to ±0.008 mm. Setting up the robot is claimed to be easier due to a new dual mounting flange that enables a tool payload of up to 4.5 kg (10 lbs).
When paired with the working area of 400 mm x 400 mm, the GVPlus family of fluid dispensing robots are expected to offer greater versatility to configure for different types of applications. Enhancements to the CCD smart vision camera deliver images even on challenging surfaces like glass, mirrors, plastics, and non-transparent clear surfaces. To ensure accuracy, EFD’s proprietary dispensing software confirms and automatically adjusts as in-process variations occur.
