Screw Tightening Check
Automotive industry
Improved yield
Detection details
Sensors are used to check that screws have been inserted correctly at four locations in the target and to check that there are no tightening mistakes or skipped processes, helping to improve the yield in later processes.

Key installation points

Conventionally, multi-point detections were performed by installing multiple sensors. However, these detections can be performed stably and easily with a single IV2 Series unit.
Also, the position adjustment function can be used to track target misalignment to the top, bottom, left, or right as well as in the rotation direction.
Furthermore, multiple product types can be supported because it is possible to easily switch between product types with the monitor and with external signals.
