Gripping Module: Innovative Solutions for Efficient Automation and Precision Gripping

Mechanical Gripper Modules

Mechanical gripper modules use moving elements to grip objects:

• Parallel grippers with synchronously moving gripper fingers
• Centric grippers for precise positioning
• Angular grippers with pivoting gripper jaws
• Multi-finger grippers for complex geometries

The precise force transmission and defined gripping positions make these modules the ideal solution for structured environments with similar workpieces.

Vacuum-Based Gripper Modules

For sensitive or irregularly shaped objects, vacuum-based gripper modules offer decisive advantages. They allow gentle handling without mechanical stress on the surface and permit the simultaneous pickup of multiple parts with one gripper module.

Their adaptability to different workpiece geometries combined with a compact design makes them particularly valuable in the packaging industry, electronics manufacturing, and when handling sensitive materials.

Magnetic Gripper Modules

For ferromagnetic materials, magnetic gripper modules are often used.

This technology offers several advantages:

• Fast pickup and release without waiting times
• High holding forces with compact design
• Low susceptibility to contamination
• Energy-efficient solutions using permanent magnets

This gripping technology is particularly often used in metal processing and the automotive industry.

Versatile Application Areas of the PRECIGRIP System

The PRECIGRIP gripper construction kit was developed for maximum flexibility and is used in various industrial sectors for handling:

• Plastic components with the most diverse geometries
• Sensitive textiles and flexible materials
• Precise medical components
• Batteries and electronic assemblies
• Cardboard boxes and packaging materials
• Sheet metal parts, wooden elements, and insulation materials

Assembly is done entirely without T-slot nuts, with external clamping, and utilizes pipe cross-sections for maximum rigidity.

Revolutionary Mounting Technology without T-Slot Nuts

The greatest advantage of the PRECIGRIP system lies in its unique construction: Subsequent insertion of components into an existing system is possible without conventional T-slot nuts. This innovative solution significantly simplifies handling and saves valuable time during configuration and changeover.

This technology results in numerous practical advantages:

• Significant time savings during assembly
• Increased flexibility when adapting to new tasks
• Reduced complexity due to fewer individual parts
• Simplified warehousing and spare parts supply

Core Components of the PRECIGRIP Construction Kit

The modular system includes perfectly coordinated components that can be flexibly combined:

Basic structural elements:

• Gripper change system (10.0) for fast tool change
• Profiles (15.0) as a stable base for individual grippers
• Profile accessories (20.0) and profile connectors (25.0)
• Clamping pieces (30.0) for tool-free fastening

Special gripping elements:

• Gripper arms for suction grippers (40.0) and active elements (45.0)
• Suction grippers (55.0) in various shapes and materials
• Gripping pliers (60.0), parallel grippers (63.0), and gripper fingers (65.0)

This variety of components allows the configuration of optimal gripper modules for every conceivable application.

Precision and Repeatability

Modern manufacturing processes require the highest accuracy in every handling operation. Gripper modules must therefore meet the highest precision requirements:

• Positioning accuracies in the tenth-of-a-millimeter range
• Constant gripping forces over thousands of cycles
• Minimal tolerances in gripping positions

This precision is particularly indispensable in electronics manufacturing, medical technology, and precision mechanics.

Dynamics and Speed

Shorter cycle times in production demand dynamic gripper modules. The fast and safe movement of the grippers significantly contributes to overall performance. Modern systems are characterized by optimized mass distribution and highly dynamic drives that work reliably even at high acceleration values.

Intelligent Functionality

Modern gripper modules are increasingly evolving into smart components:

• Integrated sensors for force and position monitoring
• Direct communication with the robot controller
• Self-diagnosis and predictive maintenance functions
• Adaptability to different workpiece variants

These intelligent functions significantly increase process reliability and reduce downtime.

Electronics and Semiconductor Industry

Electronics manufacturing presents special challenges for gripper modules. Here, electrostatic dissipative materials for ESD-sensitive components and highest positioning accuracy are crucial. Additionally, many components must be cleanroom compatible and exert particularly gentle gripping forces to avoid damaging sensitive parts.

Food and Pharmaceutical Sector

Strict hygienic regulations apply in these sensitive areas. Gripper modules must be made of FDA-compliant materials and have a hygienic design without dirt traps. Easy cleaning and sterilizability, as well as corrosion resistance to cleaning agents, are essential properties here.

Automotive Industry and Metal Processing

Robust applications in metal processing require durable gripper modules with high load capacities for heavy components. The systems must be resistant to dirt in harsh environments and resistant to oils and cooling lubricants. Reliability in multi-shift operation is particularly important.

Increase in System Performance

Optimized gripper modules improve the performance of the overall system through:

• Shortened cycle times due to fast gripping operations
• Reduced downtime due to higher reliability
• Lower scrap rates due to more precise handling

Increased Flexibility and Future Viability

Modular systems like the PRECIGRIP gripper construction kit offer decisive advantages for the adaptability of production. They enable a quick reaction to changing requirements and simultaneously reduce investment costs through their modularity and reusability.

Optimized Total Cost of Ownership

High-quality gripper modules reduce long-term operating costs through extended service life, minimized maintenance effort, and lower spare parts requirements. The improved product throughput further contributes to economic efficiency.
