Error proofing with an advanced Real-Time Location System for

Automotive seat assembly

All critical assembly actions like buckle belt, backseat marriage, side airbag tightenings are done in the right position at the right time

Optimize your seat assembly

Car seats are essential components for ensuring safety, comfort, and vehicle control. They not only provide ergonomic support and stable driver posture but also protect occupants — particularly children — by absorbing crash energy and minimizing the risk of ejection in impact events.

Typical customer challenges

Freedom of movement

In seat assembly, operators need unrestricted mobility to work efficiently around the seat. Traditional corded nutrunner can limit movement and reduce flexibility during tightening operations. Therefore more wireless nutrunners are used for seat assembly, which demands a wiresless positioning system
Close screw distance

Seat assemblies often include several fastening points placed in tight proximity. For example the screws of side airbag are around 8 – 10mm to each other. Risk of tightening the wrong screw or miss tightening a screw is significantly higher.
Line of sight obstruction

When tightening the screws of the seat on left and right side such as backrest marriage. The backrest of the seat can obstruct the view of a traditional optical system. Makes it difficult to maintain reliable position tracking during the assembly.

How can nexonar solve these challenges?

Upgrade your manufacturing process with advanced technology that prioritizes safety, ergonomics, and efficiency. By reducing recall risks and optimizing workflows, you can ensure a more reliable and productive operation.

Freedom of movement - wireless infrared technology

nexonar’s infrared-based tracking technology operates completely wirelessly, perfectly complementing cordless tools and enabling full freedom of movement for the operator while maintaining the position tracking of each step.
Close screw distance – high accruacy

The system delivers sub-millimeter precision, real-time position tracking, ensuring every tightening operation is performed at the correct position—even when screws are positioned closely together.
Line of sight obstruction – camera clustering

By combining multiple cameras into a synchronized cluster, nexonar maintains tracking continuity even when certain screws are hidden from one side of the view. As long as one camera detects the tracker, the system continues to function flawlessly, ensuring process reliability at every step.
