Overview

The AGG series grippers are precision coupling devices designed to ensure exact centering between a robot and a mould. This precise alignment is critical when metal inserts need to be positioned inside the mould before plastic injection molding.

Product Description

The AGG gripper system consists of two main components: the gripper unit (AGG...-B) mounted on the End Of Arm Tooling (EOAT) of the robot, and the steel bushing (AGG...-C) fixed on the mould. When the robot approaches the mould, the gripper is pressurized, causing it to close and engage securely with the bushing.

There are different variants of the gripper:

• AGG21-B and AGG30-B: Double-acting grippers equipped with a safety spring that maintains engagement even if compressed air supply fails (Normally Closed - NC).
• AGG19-B: Single-acting gripper with a reset spring (Normally Open - NO).

Technical Specifications

Functional Description

The gripper engages by pressurization, which closes the gripper jaws to couple with the mould bushing. The double-acting models (AGG21-B and AGG30-B) include a safety spring that ensures the gripper remains engaged even if compressed air is lost, enhancing operational safety. The single-acting AGG19-B uses a reset spring and requires air pressure to engage.

Dimensions and Weight

Dimensions are provided in millimeters and vary by model. Key dimensions include:

• AGG21-C: Diameter 20 mm, length 70.5 mm, weight 85 g.
• AGG30-C: Diameter 30 mm, length 136 mm, weight 390 g.
• AGG19-B: Smaller size with corresponding dimensions and weight around 25 g.

Detailed dimensional parameters such as thread sizes, lengths, and diameters are specified for precise integration.

Applications and Usage Recommendations

The AGG grippers are primarily used in robotic automation for plastic injection molding processes where metal inserts must be accurately positioned inside the mould. The precise centering capability reduces misalignment risks and improves product quality.

Recommended operating conditions include maintaining the specified pressure ranges and temperature limits to ensure reliable engagement and longevity of the gripper components.

Critical Parameters and Limitations

• Maximum axial loads must not be exceeded to avoid mechanical failure.
• Operating pressure must be within the specified range for each model.
• Temperature should be maintained between 5°C and 60°C to prevent material degradation.
• Double-acting models provide fail-safe engagement; single-acting models do not.

Summary

The AGG series coupling grippers from Gimatic provide a robust and precise solution for robotic mould engagement in injection molding applications. Their design ensures secure and repeatable positioning of metal inserts, with options for fail-safe operation. Detailed technical specifications and dimensional data support proper selection and integration into automated systems.
