PreciGrip System - Core Engineering Concept
The PreciGrip EOAT platform is built on a modular architecture based on a 90-degree mounting principle. With this design approach, all active and passive components on the gripper are positioned perpendicular to the robot arm axis, maximizing mechanical rigidity and structural stability.
The main engineering objectives of the system are:
• High repeatability
• Low deflection and vibration
• Fast configuration changes
• Minimal assembly time
• Long service life
Thanks to this approach, PreciGrip EOAT solutions provide a clear advantage in automation applications where cycle time is critical.
Modular Structure and Component Ecosystem
The PreciGrip Gripper Construction Kit offers an exceptionally wide configuration range with more than 2,500 standard EOAT components. These components are engineered to be fully compatible with different robot brands, payload capacities, and product geometries.
The main component groups within the system are as follows:
Quick-Change Systems
• Mechanically locked quick-change adapters
• Pneumatic and semi-automatic quick-connection options
• Prismatic locking design ensuring high positional repeatability
• EOAT changeover without stopping the robot
These systems significantly reduce downtime, especially in multi-product production lines.
Prism Profiles and Load-Bearing Structures
The prism profiles used in the PreciGrip system form the primary load-bearing structure of the EOAT.
• Profile options with different cross-sections and rigidity classes
• Lightweight yet high-strength aluminum construction
• Integrated pneumatic and cable routing within the profile
• Assembly concept without the need for T-slot nuts
This structure provides major advantages in applications that require later additions or design revisions.
Profile Connection Elements
• 90-degree, 180-degree, and adjustable-angle connectors
• Rotating and fixed connector options
• Capability to shape EOAT geometry in three dimensions
This allows customized gripper designs for complex part geometries to be created easily.
Gripper Arms and Extension Elements
• Fixed, adjustable, and spring-loaded gripper arm types
• Specialized heads for vacuum cups and mechanical grippers
• Rotating and angle-adjustable arm designs
Gripper arms ensure precise positioning of active contact elements and provide optimal contact angles on the product surface.
Vacuum Handling Systems
The PreciGrip EOAT kit includes a wide range of vacuum solutions:
• Round, oval, and custom-shaped vacuum cups
• Silicone, NBR, and polyurethane material options
• Single or multi-line vacuum integration
• Spring-loaded and swivel vacuum cup holders
Vacuum systems enable deformation-free handling of sensitive or thin-walled products.
Mechanical and Parallel Grippers
• Pneumatic parallel gripper solutions
• Various stroke lengths and piston diameter options
• Sprue pickers and special cutting grippers
• High gripping force combined with low weight
These grippers are widely used in plastic injection molding, metal part handling, and assembly applications.
Sensors and Pneumatic Accessories
• Part presence detection sensors
• Vacuum pressure sensors
• Pneumatic valve islands and manifolds
• Pre-assembled hoses and connection sets
These components enhance process control and operational safety of the EOAT system.
Technical Advantages and Performance Benefits
Key technical advantages of the PreciGrip EOAT Gripper system include:
• Precise and stable gripping thanks to high structural rigidity
• Fast assembly and adjustment using a single tool
• Ability to add or remove components without dismantling the EOAT
• Optimized load distribution on the robot arm
• Durability suitable for long-term industrial operation
These benefits reduce maintenance costs while increasing production continuity.
