Screw robot for controlled screwing in series
Whenever manual screwing reaches its limits, a screw robot from gKteso ensures consistent quality and stable processes. We automate screwing, document all steps, and simultaneously enable flexible adjustments, ideal for changing products and series production with high demands.
Our screw robot: Automations from gKteso
The screw robot is integrated into the robot cell of gKteso and forms the central module for automated screwing. The cell handles screwing processes for components with different geometries and quantities. It is suitable for series parts with consistent contour as well as for variant production with frequent product changes. All screwing steps can be completely documented and traced, including torque, screw-in depth, and timestamp.
Depending on the application, we use electric screwing systems with regulated torque or force-controlled screw spindles with path measurement. The feed system automatically brings screws into the receiving position, either via vibratory bowl or pick-and-place feeding. The robot positions the screws with repeat accuracy within a tenth of a millimeter directly on the component. The central control monitors all process parameters in real-time and immediately detects deviations.
Structure of the screw cell from gKteso
The strength of the robot cell lies in the interaction of all components. Inside work:
a 6-axis robot with an integrated screw spindle for position-accurate screwing
an automatic feed system or magazine for providing screws
an integrated documentation unit for seamless storage of all process data
Camera systems and sensors for precise component recognition and position correction
a centrally controlled system for monitoring torque, screw-in depth, and screwing duration
The screw robot cell operates autonomously and can be seamlessly integrated into existing production lines. Through interfaces like Profinet or OPC UA, it communicates directly with your PLC or MES. This way, the screwing process is seamlessly integrated into the overall process.
When manual screwing fails, screw robots take over
Screwing processes require precisely defined force, constant repeat accuracy, and complete control over the tightening torque. In practice, however, fluctuations often occur. Screws are tightened too much or too little, are crooked or in the wrong position. In small components or safety-relevant parts, this leads to failures, increased rework, and unnecessary production delays.
Your advantages with the screw robot from gKteso
Our screw robot tightens every connection with precisely regulated torque, positions each screw precisely on the workpiece, and documents every single operation. This reduces scrap, lowers inspection costs, and increases process reliability, especially in areas such as medical technology, sensor technology, or electronics assembly.
Process-safe screwing with traceability
The screw robot tightens each connection with precisely defined torque. The system stores screw-in depth, position, and time per component and documents all processes automatically. This way, you ensure safety-relevant connections are secured long-term and meet quality standards without additional effort.
Lower scrap rates through regulated processes
Regulated processes avoid typical assembly errors such as crooked or over-tightened screws. You save on rework, reduce scrap rates, and increase production safety with each batch.
High output even with variants
The robot cell processes up to 200 components per hour, even with changing geometries. Via software, you load new programs and start directly with the next series. This reduces changeover times and increases utilization.
Relief for specialists in assembly
The screw robot takes over monotonous and physically demanding tasks. Your staff supervises several cells simultaneously and focuses on overarching activities. This increases productivity per shift and reduces physical strain.
Seamless integration into existing production lines
We integrate the screw robot cell directly into your existing line. You continue to use existing infrastructure and do not need external controls or modifications. Via Profinet or OPC UA, you directly connect the cell to PLC or MES.
Flexible adaptation to component variants and product changes
The screw robot cell recognizes different geometries through integrated sensors or software presets. You change components without mechanical adjustments and adapt the process via program selection. This reduces downtime and makes even smaller series economical.
