2026-01-14From “Uncontrollable” to “Fully Controllable”: The Core Value of Electric Grippers
If traditional air grippers solved the problem of “whether” you can grip, electric grippers solve the problem of “how well” you can grip. Their core value lies in upgrading a simple action into a quantifiable, traceable, and precise control process.
| Performance Metric | Traditional Pneumatic Gripper | wlbrobot Electric Gripper | Value to Your Design |
|---|---|---|---|
| Force Control | Uncontrollable or complex to adjust. Force is highly sensitive to air pressure fluctuations. | Programmable Control. Clamping force can be precisely set in the program, with accuracy down to the Newton. | Protect Valuable Workpieces: Use a “gentle” force to handle fragile or easily scratched parts (e.g., lenses, chips), preventing defects. |
| Position Control | Only two limit positions: fully open and fully closed. | Multi-Point Positioning. Can stop at any point within the stroke. The opening width is freely programmable. | One Gripper, Multiple Parts: Handle different-sized workpieces without changing the gripper or mechanical hardware, enabling true flexible production. |
| Speed Control | Difficult to control precisely; typically closes at full speed with high impact. | Programmable Control. The speed and acceleration of closing and opening are adjustable for smooth motion. | Improve Cycle Time & Lifespan: Reduces impact and ensures smooth operation. Optimize gripping speed to match cycle time needs while reducing mechanical wear. |
| Data Feedback | Can only determine open/closed status via external sensors. | Built-in Data Feedback. Provides real-time feedback on the gripper fingers’ actual position, grip status (success/fail), and whether a part has been dropped. | Enable Intelligent Closed-Loop Control: Provides the data foundation for predictive maintenance, quality traceability, and smart decision-making (e.g., auto-retry on a failed grip). |
Inside the Core: How wlbrobot Electric Grippers Achieve Precision Control
The reliability and precision of wlbrobot electric grippers stem from their robust internal mechanical design and transmission structure.
- Core Drive: We don’t use simple, flimsy motors. Instead, a miniaturized ball screw drive mechanism is ingeniously integrated within the compact housing. This ensures high drive efficiency and rigidity, which is fundamental to achieving precise force and position control.
- Precision Guidance: The gripper fingers are guided by a high-precision linear guide rail. This ensures that even when subjected to off-center moment loads, the fingers move smoothly and linearly without wobble, guaranteeing high repeat positioning accuracy. This is a fundamental difference from low-end products that rely on simple slide grooves.
Application Analysis: The Real-World Value of wlbrobot Electric Grippers
- 3C Electronics: Flexible Loading/Unloading of Smartphone Frames
- The Pain Point: A production line needed to process multiple models of smartphone frames with size differences of 5-10mm. The traditional pneumatic solution required a separate gripper for each model, leading to long changeover times.
- The wlbrobot Solution: By using our two-finger electric gripper and communicating with the robot or PLC, the opening width for each model was pre-set in the program. When switching products, a simple program call automatically adjusts the gripper to the correct opening in less than 0.5 seconds, achieving a truly seamless changeover.
- Medical Device Industry: Precision Sorting of Disposable Blood Collection Tubes
- The Pain Point: The collection tubes are thin-walled plastic parts. Too much force from a pneumatic gripper can crush them; too little force can cause them to be dropped during high-speed movement.
- The wlbrobot Solution: We selected our adaptive electric gripper and set a precise clamping force (e.g., 5N). Regardless of the operating speed, the gripper consistently holds the tube with a constant force, ensuring both stability and zero product damage. Furthermore, the built-in position feedback can be used to detect if a tube has dimensional anomalies.
