New functions increase speed, accuracy and user-friendliness
The Yamaha Robotics SMT Section has introduced performance-enhancing upgrades for the YRi-V 3D AOI system. They include faster handling of assemblies, a multi-component alignment check and improved LED coplanarity measurement.

The new, stop-free transport system brakes and stabilizes each assembly electronically after it enters the machine, thus reducing the time required to position the assembly. The cumulative time saving accelerates the completion of each batch and thus noticeably increases overall productivity.
The new alignment test for multiple components simplifies the programming of the YRi-V for measuring the distances between components arranged next to each other, such as LED spotlights in automotive or general lighting. In the production of automotive headlights, users can use the recorded AOI position data to individually optimize the placement of the lenses for beam focusing for optimum light output. The alignment test can be used to determine the distances between numerous other components, such as Hall sensors for precise motion control. 
The multi-component test helps to set up the YRi-V to measure component alignments and distances in order to make corrections or record positions
The advanced height measurement system based on a blue laser ensures accurate and repeatable height measurement for components such as transparent LED housings, which can only be measured to a limited extent with conventional systems. The YRi-V system now offers even more possibilities and helps lighting manufacturers to ensure higher product reliability with superior optical performance and optimized visual appearance. The YRi-V system can also be equipped with a 25 megapixel camera, which significantly expands the image area that can be captured simultaneously.
“The latest upgrades expand the YRi-V system’s ability to optimize quality assurance to support the most advanced automotive, industrial and consumer applications,” says Daisuke Yoshihara, General Sales Manager. “Our customers benefit from ongoing improvements to their YRi-V systems, as we continuously provide new functions that are made possible by developments such as new machine vision technologies, motion control and AI.”
Yamaha’s YRi-V 3D AOI systems, like the YRM high-speed placers, are based on highly rigid frames that form the basis for super-sharp image capture with maximum line performance. With multiple camera resolutions, an 8-directional 3D projector and a state-of-the-art image processing unit, the system achieves extremely high throughput and detects hard-to-detect defects such as flaking and cracks in wafer-level packages. Offline editing tools and AI-supported automatic library matching accelerate the creation of inspection programs and help to minimize the time required to introduce new products. There are also tools that facilitate the creation, conversion and fine-tuning of data. During operation, fault information is immediately exchanged with other devices on the line via M2M communication to speed up analysis and troubleshooting.
As an integrated part of the 1 STOP SMART SOLUTION concept, the YRi-V system is connected to Yamaha’s complete SMT equipment. This includes solder paste printing and inspection, high-speed assembly and smart factory software and ensures a high level of integration and coordination. The latest functions for flawless transport, alignment inspection and laser height inspection are now available for all new machines and for upgrading existing systems in the field.
