Robotic gripper refers to an automatic operation device with the ability to imitate the hand and arm of some action functions, in order to grasp fixed procedures, carry objects or handle tools. The robotic gripper is the earliest industrial robot, and also the earliest modern robot. It can replace heavy manual labor to achieve mechanization and automation of production and can operate in a harmful environment to protect personal safety. The robotic gripper is mainly divided into two parts, the arm and the robotic end-effector. The arm uses joint movement to drive the end-effector to reach the preset position for the preset operation.
The gear DC motor for robot gripper is a small-power micro transmission gear motor, whose main transmission structure is assembled by a driving motor (micro motor) and planetary gearhead (reducer). It is applied to the transmission gear motor module of robotic arm and gripper, short for “robotic gripper motor”. The driving motor can adopt DC motor, brush motor, BLDC motor, servo motor, stepper motor, coreless motor and micro motor as the driving source while the micro gearbox can adopt planetary gearhead, cylindrical gearhead, and worm gearhead as the reducer. The technical parameters are often customized for developments, including the output power, gear ratio, output torque, voltage, type of driving motor, the structure of gearbox, transmission noise, transmission precision, etc.

Project Name: Gearbox Solution for Robot Joints
Project Background: In the interaction between communication and rapid response, DC gear motor is used to drive the robot joints, which requires a larger power-to-weight ratio and torque-to-inertia ratio, higher starting torque, low inertia and wide & smooth speed adjustable range. In particular, the robotic end-effector (gripper) should adopt the joint motor with compact size, light weight and large short-time overload capacity.
Solution: Based on the development and exploration on abrasion-proof material technology, processing optimization techniques, lubrication technology, packaging technique, life testing technology and transmission mechanism, ZHAOWEI develops and manufactures micro robot joint gearboxes to improve the performance of intelligent robot including perception and identification, mechanism and transmission, control and interaction, etc. The full range of precision robots adopts gear motor with planetary gearhead whose parameters can be customized (diameter: 3.4mm-38mm, power: 0.01-40W, output speed: 5-2000rmp, gear ratio: 5-1500, output torque: 1.0 gf.cm -50kgf.cm).
