Introduction to backlash-free gearbox compensation in pick-and-place robots
Target deviations in pick-and-place robots incur costs. Precision in automated manufacturing is critical. This article explains how optimized gearbox compensation improves performance and minimizes downtime, especially in pick-and-place robots..
Positioning errors can halt production lines. Costs arise from accumulated effects on throughput.. Packaging systems show efficiency losses of up to 15%. Pick-and-place systems are particularly susceptible to gear backlash due to their high dynamics. Effective play compensation is therefore essential. Robotic applications.
Fast start-stop movements and direction changes exacerbate gear backlash issues. Specifically, pick-and-place tasks amplify the effects of gear backlash. With short cycle times (Kawasaki Robotics, 0.2s), this is critical, and the backlash-free gearbox compensation for such robots becomes a necessity. Compact servo gear motors are performance-relevant.
Optimal performance requires a holistic approach. Mechanical excellence and advanced software compensation are crucial for fully unleashing performance, especially in terms of the backlash-free operation of gearboxes in handling robots . Systems like ABB’s IRB 340 leverage this synergy. Backlash-free planetary gears are commonly used.Basics and importance of backlash-free gearbox compensation
Gear backlash (“backlash”) is unwanted mechanical play in drive systems. Uncompensated, it leads to deviations (e.g. 0.5 mm), which is why the gearbox compensation compensation is so important. Precise gear motors minimize this.
Uncompensated play leads to scrap, rework, and increased wear on components. A VDMA study shows: maintenance costs can increase by up to 20% if adequate compensation of gear backlash is not taken into account. In semiconductor manufacturing, high-precision gearboxes are required.
Maximum precision is often necessary. In medical technology and electronics manufacturing, where μm-accuracy is required, backlash-free gearbox compensation is essential for the exact positioning of the smallest components, especially in pick-and-place applications..Technologies and methods to achieve backlash-free gearbox compensation
Mechanical approaches such as pre-tensioning and precision manufacturing already structurally minimize gear backlash. High-precision servo-ready planetary gears reduce backlash to values of under 3 arc minutes thus creating a solid foundation for subsequent software compensation, a key component of the backlash-free gearbox compensation.Gears are selected in pairs, for example, to maximize fit accuracy.
- Mechanical approaches: pre-tensioning and precision manufacturing minimize initial gear backlash.
- High-precision components: servo-ready planetary gears reduce backlash to values like <3 arc minutes.
- Software compensation: modern controllers use algorithms for real-time compensation of residual play.
- Feedback systems: encoder data allow for precise adjustments and corrections.
- Performance enhancement: software can significantly improve tracking accuracy (e.g. KUKA +70%).
- Optimal strategy: the combination of robust, low-backlash mechanics and intelligent software compensation.
Software solutions actively compensate for residual play. Modern controllers use sophisticated algorithms that compensate for gear backlash in real-time using encoder feedback.. KUKA systems can achieve an improvement in tracking accuracy of up to 70%. Approaches like this zero-play adjustment often require high-torque servo gear motors..
Die The most effective strategy for comprehensive backlash-free gearbox compensation, especially for dynamic pick-and-place robots, is the combination of robust, low-backlash mechanics and intelligent software compensation. ATEK Drive Solutions combines high-quality brushless servo gear motors with advanced control strategies for optimal results.Challenges and best practices
The implementation of an effective gearbox compensation poses challenges. The initial calibration is time-consuming and requires specific expertise (often several hours per axis). However, users like HORST robotics confirm the long-term benefits of careful play compensation. For special requirements, such as in robotics, high-precision bevel gearboxes are employed.
Die Auswahl der richtigen Technologie für den gearbox compensation is crucial. The decision must take into account load profiles, required speeds, and environmental conditions, not just the theoretical residual play of the gearbox.. An integrated planetary gearbox can offer advantages here. A careful design of the entire drive train is essential for the success of the backlash-free gearbox compensation in pick-and-place robots. Continuous monitoring and preventive maintenance are essential to ensure the long-term performance of the gearbox compensation.
