DEPRAG HRC screwdriving system – safe, flexible and without a safety fence
With the DEPRAG HRC screwdriving system, humans and robots can work safely in the same workspace without a safety fence. A passive protective skin and a non-contact sensor ring trigger an immediate safety stop upon intervention or contact. As soon as the protective field is clear, the robot automatically resumes the process. This expands DEPRAG screwdriving units to include a system for safe, flexible assembly stations.

When automation needs to remain flexible
True human-robot collaboration remains difficult with traditional robot cells. While safe, they are often inflexible: safety fence here, release there, standstill in between. Especially with highly variable products, frequent changeovers, or manual intermediate steps, safety fence concepts quickly reach their limits.
The DEPRAG HRC screwdriving system closes this gap in assembly automation. It combines collaborative robotics with the proven DEPRAG Feed Module (DFM), enabling humans and robots to work together productively in the same workspace. This is achieved without separating safety barriers, yet still safely. The robot stops when necessary and then automatically resumes work, just as required by everyday assembly processes.
The advantages of the DEPRAG HRC screwdriving system
- Increased safety for the worker:
Intervention or contact? The robot stops immediately. Compliant with DIN ISO/TS 15066.
- Increased throughput & less downtime:
The robot only stops in case of an incident and then continues automatically.
- Greater flexibility in assembly:
humans and robots work in parallel in the same workspace.
- Less space required:
No separating protective devices, no unnecessary safety zones.
- Quick start & retrofitting:
Existing manual workstations or DEPRAG screwdriving units can be converted to a collaborative robot solution.
This is how the system works:
The security concept is deliberately simple and therefore reliable.
A protective cover covers the sharp corners and edges of the screw unit.
A non-contact sensor ring monitors the protective field around the tool.
If an unexpected intervention occurs, a safety stop is triggered immediately. Once the workspace is clear again, the robot automatically resumes its movement. No complicated procedures. No unnecessary downtime.
HRC screwdriving system for collaborative assembly processes
Robots are indispensable in modern production. At the same time, humans remain essential in many applications, such as positioning, testing, or rework. The HRC screwdriving system enables precisely this efficient human-robot collaboration (HRC) without unnecessarily slowing down or complicating the process with fences or separating safety devices.
The safety concept combines a passive protective skin with a non-contact sensor ring. If the protective field is breached or pressure is applied, a safety stop is triggered immediately. As soon as the protective field is clear again, the robot automatically resumes the process – without manual intervention.
Another advantage: In areas where protective barriers are in place and there is no danger to the operator, the safety function of the sensor ring can be deactivated. The robot then operates at a higher speed. Ideal for productive cycle times combined with high process reliability.
