Description

Technical Field

[0001] The utility model relates to the technical field of robot telescopic arms, in particular to a robot telescopic arm. Background Art

[0002] A robotic telescopic arm is a mechanical arm with telescopic capabilities. Its principle is similar to that of a human arm, consisting of multiple segments connected by joints. The telescopic arm's telescopic ability is achieved through relative motion between all segments. This design improves the robot's working range, flexibility, and adaptability, enhancing its operational capabilities. Robotic telescopic arms are widely used in industrial production, enabling fast and accurate logistics movement and product manufacturing.

[0003] The prior art authorization announcement number is CN219170920U, which is an industrial robot telescopic arm. It includes a base, a turntable, a first motor, a boom and a steering mechanism. The turntable is rotatably connected to the base. Two connecting plates are fixed to the turntable. The outer sides of the connecting plates are fixed to the first motor. The output ends of the first motor are fixed to both sides of the bottom end of the boom. The bottom of the steering mechanism is hinged to the top end of the boom. The steering mechanism includes a first ball seat, a small arm and several hydraulic rods. A ball socket is provided on the first ball seat.

[0004] Although the robot's telescopic arm has a higher degree of freedom, its air gripper is directly installed at the end of the second small arm and no steering mechanism is set. This means that when the operating angle of the second small arm changes, the operating angle of the air gripper also changes accordingly. Its grasping angle cannot be adjusted according to actual needs, resulting in a large limitation on the overall range of use. For this reason, improvements are proposed. Utility Model Content
