Precision & Rotary Position Detection for Electric Stove Circuit Assembly

Overview

Small deviations of circuit elements in electric stove manufacturing in either position or orientation can affect performance and durability. To ensure accuracy and consistent quality, a vision-guided assembly solution was implemented to detect each component’s position and rotational alignment before robotic placement. This replaces the guesswork and introduces an automated, intelligent layer of verification and correction.

Challenge

The challenge was not only figuring out exactly where each circuit element was positioned and how it was rotated but also doing that with the same high level of accuracy every time. Variability in incoming parts, slight shifts in fixtures, or accumulated mechanical tolerances could all lead to misalignment. Without an intelligent detection system, these deviations had the potential to disrupt downstream assembly steps, reduce reliability, and require manual rework. The client needed a system capable of reading each component’s exact spatial data in real time and communicating this information to multiple robots operating in sequence.

Solution

To meet these demands, senswork integrated high-resolution industrial cameras into the assembly flow. These cameras analyze every component’s absolute position while simultaneously measuring its rotational angle. Custom image-processing algorithms identify key reference contours and features, allowing the system to determine both the linear position and the angular alignment of the part with exceptional accuracy. Once measured, this data is transmitted directly to the robots on the production line, enabling each robot to make precise adjustments. The result is a self-correcting process that adapts automatically to small variations and ensures every component is aligned exactly as intended.

Benefits

• Position determination accuracy of ±0.1 mm
• Angular position determination accuracy of ±0.2°
• High precision and reliable measurement stability
• Automated detection and compensation for positional and rotational deviations

Conclusion

This system significantly enhanced production reliability by providing consistently accurate data, even under continuous operation. The vision-based detection allowed the robots to perform placements with extremely tight tolerances, ultimately improving product quality and reducing dependency on operator intervention. By building precise, automated corrections into the process, the manufacturer was able to automate assembly accuracy and improve efficiency, resulting in more reliable electric stove circuits.
