Two Finger Electric Gripper is an automated execution device powered by electricity that achieves object grasping through the opening and closing actions of two "fingers" (grippers). It is a common end effector in industrial robots and automated production lines. Its core function is to simulate the gripping action of human fingers and complete tasks such as stable grasping, handling, assembly, or release of objects.
Two Finger Electric Gripper is an automatic clamping device driven by an electric motor, which uses two parallel or opposing moving gripping fingers to complete object grasping, fixation, or handling operations. It is the most fundamental and widely used type of electric gripper in the field of industrial automation.
In practical applications, Two Finger Electric Gripper and Two Jaw Electric Gripper are often seen as different expressions of the same type of equipment, with the core difference being only in terminology conventions: Jaw "emphasizes the" claw "in mechanical structures, while" Finger "focuses more on simulating the function of human fingers. Both essentially refer to" two gripper/finger electric grasping devices ", with highly consistent working principles, structures, and application scenarios.
The design inspiration for Two Finger Electric Gripper comes from the collaborative mode of human fingers, and its core features and structure can be summarized as follows:
|
Dual finger execution mechanism |
Contains two "fingers" that move relative to each other (usually referred to as "grippers" or "claw fingers"), |
with materials selected according to the application scenario, such as metal (such as aluminum alloy, stainless steel, suitable for heavy or high temperature environments), plastic or rubber (suitable for light loads, fragile objects such as glass, electronic components, can increase friction and avoid scratches). |
|
The tips of the fingers can be flexibly replaced with "fingertips" (such as flat fingertips, V-shaped fingertips, curved fingertips, anti slip patterned fingertips) |
adapting to objects of different shapes (circular, square, flat) and sizes (from millimeter sized parts to tens of centimeters of workpieces). |
|
|
Electric drive and transmission system |
The power source is a motor (commonly a servo motor or stepper motor) |
which is driven by electricity to achieve finger opening and closing movements without relying on air pressure or hydraulic pressure, making it more environmentally friendly and precise in control. |
|
The transmission mechanism usually includes gear sets, screw rods, connecting rods or synchronous belts. |
which convert the rotational motion of the motor into a linear opening and closing motion of two fingers (mostly symmetrical synchronous motion, that is, two fingers approach or move away from the center at the same time, ensuring the stability of the clamping center). |
|
|
Precise control capability |
Support position control |
precise control of finger opening and closing stroke through motor encoder (such as minimum opening 5mm, maximum opening 100mm), ensuring the accuracy of grasping size. |
|
Support Force Control |
Some high-end models have built-in force sensors that can detect clamping force in real time (adjustable from 0.1N to 500N), avoiding objects (such as food and glass) from being damaged by excessive force or falling off due to loose clamping. |
|
|
Fast response speed |
rogrammable opening and closing speed to adapt to different scene requirements (such as low-speed clamping of fragile items and high-speed action during efficient production). |
