Robotic Parallel Gripper Overview
What Is a Robotic Parallel Gripper?
A robotic parallel gripper is a specialized end effector designed for use with robotic arms, particularly in electronics assembly. This type of gripper uses two jaws that move in parallel to grip, hold, and release objects. The parallel motion allows the gripper to handle components with high accuracy and repeatability. In the context of robotics, the term “parallel manipulator” refers to a mechanism where multiple arms or links work together to control movement. A parallel gripper operates on a similar principle, using synchronized jaws to achieve precise control over small parts. This makes it ideal for tasks that require meticulous handling, such as placing microchips or connectors on circuit boards.
Parallel grippers stand out due to several key design features:
- Meticulous control over gripping force, which is essential for handling fragile electronic items.
- Adaptability with soft or compliant jaws for delicate parts, and sturdier jaws for heavier objects.
- High accuracy and narrow operational capabilities, making them suitable for precision tasks.
- Two-jaw configuration that provides secure handling of symmetric and repeatable parts.
Note: Parallel grippers can handle a wide range of shapes and sizes, enhancing their versatility in electronics assembly.
Core Functions
The core functions of parallel grippers focus on reliable and efficient handling of electronic components. These grippers use a linear motion to move their jaws together or apart, ensuring a secure grip on each part. The actuation mechanism often involves electric motors, such as servos or steppers, which convert rotational motion into linear movement. This design allows for programmable adjustments to finger stroke, force, and speed.
| Principle | Description |
|---|---|
| Actuation Mechanism | Electric motors actuate the gripper, often using a 4-bar linkage. |
| Motion Translation | Motor rotation converts into linear motion for the gripper fingers. |
| Synchronization | Gears or a single screw mechanism ensure the fingers open and close together. |
| Finger Stroke Adjustment | Electric grippers allow programming of finger stroke, force, and speed. |
| Gripping Limitations | Parallel grippers establish only two contact points, limiting their ability to grasp irregular parts. |
Parallel grippers, such as electric parallel grippers, provide high positioning accuracy and repeatability. They use microprocessors to vary gripping force and speed, and force sensors help determine the right amount of pressure for each task. Some models, like the Hand-E gripper, feature sealed designs that ensure reliable operation even in challenging environments, such as CNC machining or slightly dirty settings. Adjustable force and self-locking functions make these grippers adaptable to different products, while rounded edges improve safety near human workers.
Benefits of Robotic Parallel Gripper
Precision and Consistency
Parallel grippers deliver outstanding precision and consistency in electronics assembly. Their design, inspired by the parallel robot, allows the jaws to move in perfect synchronization. This movement applies uniform pressure to every component, which is especially important when handling circuit boards and semiconductors. The gripper ensures that each part receives the same amount of force, reducing the risk of slipping or uneven placement. As a result, manufacturers achieve higher accuracy and repeatability in their assembly processes. Parallel grippers with customizable jaws can adapt to different shapes and sizes, further improving their ability to handle a wide range of electronic parts with consistent results.
Note: Uniform pressure from parallel grippers minimizes the risk of damage and misalignment, making them ideal for high-precision tasks.
Speed And Efficiency
Speed and efficiency are critical in modern electronics manufacturing. Parallel grippers excel in these areas by enabling rapid pick-and-place operations. Their synchronized jaws can quickly grip and release components, allowing assembly lines to operate at high speeds without sacrificing accuracy. Many factories, such as those operated by Siemens, use lightweight grippers to maintain a steady flow of printed circuit boards (PCBs) through automated systems. These grippers support continuous production, which leads to fewer delays and higher output.

How Does Robotic Parallel Gripper Work?
Operation Steps
A robotic parallel gripper uses a synchronized jaw mechanism to grip, hold, and release objects with high precision. The jaws move in parallel, similar to the movement found in a parallel manipulator. This design allows the gripper to apply even pressure on components, which is essential for electronics assembly. The operation begins when the gripper approaches a part. Sensors help position the jaws accurately. The jaws then close around the object, securing it with a controlled force.
Different types of grippers power this process. Electric parallel grippers use motors to move the jaws. Pneumatically-powered parallel grippers rely on compressed air for fast jaw movement. Servo-electric grippers offer quick response times and precise control. Adaptive grippers can adjust their jaws to fit various shapes, making them suitable for handling irregular parts.
Tip: Using sensors with parallel grippers improves accuracy and reduces the risk of damaging delicate components.
Basic Operation Steps:
- The gripper moves toward the target part.
- Sensors guide the jaws for precise alignment.
- The jaws close in parallel to grip the object.
- The gripper lifts and moves the part to the desired location.
- The jaws open to release the object.
Integration in Assembly Lines
Manufacturers integrate robotic parallel grippers into assembly lines to automate repetitive tasks. The parallel manipulator-inspired jaw mechanism enables the gripper to handle small and delicate electronic parts efficiently. Electric parallel grippers and pneumatically-powered parallel grippers offer flexibility for different production needs. The gripper can work with collaborative robots or light industrial robots, adapting to various assembly environments.
A typical assembly line uses multiple grippers for tasks such as pick-and-place, machine tending, and quality inspection. The jaws operate in sync, ensuring consistent handling of components. Programmable settings allow operators to adjust jaw speed, force, and stroke for each application.
