Improve cost efficiency by adopting an automatic laser drilling system (Part 2)

Through the advanced transfer beam and feeding system, RNA Automation has built a good foundation to improve the entire laser drilling cycle efficiency.

After passing through the transfer beam, the material is transferred to the exact location of the laser drilling station, where the most important stage of the cycle begins. The laser drilling system provided by ES Technology has vision sensors combined with the Poka-Yoke error prevention tool, allowing the operator to detect faults in real time through the control panel.

RNA invited Fisher Smith’s experts to participate in the system setting process. They are leading experts in the field of computer vision and have many years of experience configuring industrial automation systems.

After consulting, RNA technicians installed the observation system with the combination of 3 camera stations and optical sensors, making it easy to check the size and position of the hole in the plastic mold. easier than ever. Although the robotic arms have been finely set up for precise drilling operations, computer vision technology still significantly reduces the error rate during manufacturing. Not stopping there, “satisfactory” products will be collected in batches for every 1000 units and randomly sampled to check the quality criteria.

During the production cycle, the RNA system is capable of processing multiple steps at the same time, significantly reducing unnecessary downtime. Specifically, the vibrating hopper feed system allows the operator to pre-prepare new materials as soon as the laser drills are in operation. Thanks to that, the material will be loaded as soon as the drilling has finished. In addition, each product prototype is provided with a unique barcode that helps the computer system distinguish and use suitable machining tools. The computer can automatically recognize if the wrong kit is used. This validation process only takes a few seconds but significantly eliminates the risk of errors caused by subjective human causes.

A fully validated conversion process for switching from one component to another can be done in less than 5 minutes, helping to improve uptime and productivity.

Some of the benefits your organization gets when adopting an automated RNA laser drilling system are:

• Poka Yoke tool will automatically shut down the system when it detects a local error, helping to reduce the failure rate.
• Consistently coordinated component systems reduce downtime and improve whole line efficiency
• The bore tolerance is only approximately 1 micro meter
• Tooling time is less than 5 minutes
• The SPC (statistical process control) tool monitors and records data throughout the production cycle. Managers can use these data to build the most efficient cycle.
