GECKO SP1/3/5

Product catalog summary

General Specifications:
The Gecko SP1/3/5 grippers are designed for handling various payloads with maximum capacities of 1 kg (2.2 lb) for SP1, 3 kg (6.6 lb) for SP3, and 5 kg (11 lb) for SP5. They feature a preload range from 3 N to 46 N and can hold workpieces even during power loss if well-centered. The grippers have an IP42 classification and dimensions of 69 x 71 mm (2.7 x 2.8 inches). The weight varies slightly among models, with SP1 at 0.267 kg (0.587 lb), SP3 at 0.297 kg (0.653 lb), and SP5 at 0.318 kg (0.7 lb).

Material and Maintenance:
The pads are made from a proprietary silicone blend, with wear properties dependent on surface roughness. They require change-out approximately every 200,000 cycles. Cleaning can be performed using an OnRobot cleaning station, silicone roller, or isopropyl alcohol with a lint-free cloth. Operating temperatures range from 0°C to 50°C (32°F to 122°F), and storage temperatures from -30°C to 150°C (-22°F to 302°F).

Operational Guidelines:
The gripper's effectiveness is influenced by surface roughness and environmental conditions. It works best on clean, smooth, and dry surfaces. Preload force is crucial for achieving maximum payload force, and adjustments may be needed to avoid triggering robot collision detection systems. The center of gravity of the object should be centered on the gripper pad to maintain adhesion.

Effectiveness on Different Materials:
The gripper's ability to handle items is affected by the micro and macro scale roughness and stiffness of the material. A table provides guidance on the compatibility of different materials with the Gecko SP1, SP3, and SP5, using a scale from 1 to 10 for stiffness and roughness. For example, polished mirror-like steel is highly compatible, while sandblasted aluminum is less so.

Usage Notes:
Users should be aware of the pad wear and replace them as needed. The gripper's performance is optimal with highly polished surfaces, and environmental factors such as dust or debris can affect adhesion.

Datasheet How to pick a part using the Gecko Gripper SP Contact & Preload Lift Method 1 – Robot Peeling Movement: Release Method 2 – Fixturing: It is also possible for users to craft their own custom fixture to assist in peeling off an object if the above method is not desirable. For example, the Gecko SP1/3/5 could grip a panel and then visit a forked tool to slide between, move up and release the object. The fixture design is completely at the user’s discretion. Usage Notes: Because of the Gecko Gripper SP’s unique mechanism of action, it is important to understand the following key operating...

Datasheet The adhesion force is also dependent on the amount of preload force applied to the s urface. This preload force also depends on the surface smoothness or roughness. Payload force is also saturable at some preload force specific to the material and operating conditions; here maximal preload is applied. • Reconcile Gripper Function with Robot Collision Detection or Other Safety Systems When using the Gecko Gripper with a robot in position control, care must be taken during the gripping phase of the object as to not trip off the robot’s collision detection system.
