Embodiment Construction

[0036] An industrial robot end effector of the present invention will be described in detail below with reference to the embodiments and the accompanying drawings.

[0037] The invention relates to an end effector of an industrial robot, which adopts the design of a three-grab self-centering structure, and three hand grippers interact to form an end operation part. The connection between the hand clamp and the chassis is fixed by bolts. Whether the end effector can accurately clamp the product and deliver the product to the designated position depends not only on the positioning accuracy of the end effector, but also on the magnitude of the clamping error and the installation positioning accuracy. With the structural device of the present invention, according to the shape and size of the product and the requirements of the material, hardness and surface properties of the clamping part, the fingertip part is designed with a half-moon-shaped V-shaped groove surface and made of e...

Abstract

The invention relates to an industrial robot end effector, in particular to a multifunctional robotic gripper. The multifunctional robotic gripper comprising a underframe is characterized in that theunderframe is equipped with a mechanical arm; the power source of the mechanical arm is provided by a pneumatic cylinder; power is transmitted through a compressed disc spring, a connecting support and multiple hinged supports so that the mechanical arm completes the grasping action on the underframe; the mechanical arm is installed with a mechanical finger claw consisting of a finger end frame sensor and a half moon shape inner concave block; with the mechanical arm to grip products, the mechanical finger claw is self-centering and can grasp products of different shapes and sizes.

Description

technical field [0001] The invention relates to a multi-functional robot gripper, in particular to accomplish the precise grasping of relatively heavy products. Background technique [0002] Industrial robots are often used to replace humans in harsh environments such as dangerous, harmful, toxic, low temperature and high heat, extending and expanding the functions of human hands and feet. The end effector is one of the key components of the industrial robot. Its main function is to clamp the workpiece or tool, and complete the specified instructions according to the action. The clamping and loosening of the end effector are controlled by the system to issue commands. The end effector is a device that directly performs work, and it has a great influence on expanding the working function, application range and improving work efficiency of the manipulator. [0003] A well-designed end-effector of an industrial robot can greatly improve the efficiency and reliability of the sy...
