Problems solved by technology

[0003] At present, in the vast majority of occasions where small parts are processed, operations such as loading and unloading, assembly, and palletizing are still mainly done manually, and there are disadvantages such as low efficiency, high labor intensity, and poor safety when completing the above operations manually.
In addition, for some workpieces with narrow processing space, if industrial robots are used for operations, the end of the robot is required to be able to extend into the processing area, so as to facilitate the operation, which requires the end of the robot to be small and flexible, while traditional SCARA robots generally have Disadvantages of excessive bulk at the end

Embodiment 1

[0026] In this embodiment, the multi-joint robot includes a large arm and a small arm that are horizontally arranged and articulated with each other, a motion unit disposed on the small arm, and a mechanical claw for grabbing parts. The motion unit includes a lifting mechanism, The mechanical claw is arranged on the lifting mechanism so that it can move up and down along with the lifting mechanism.

[0027] Preferably, the moving unit further includes a rotating mechanism, the lifting mechanism can drive the rotating mechanism to move up and down, and the mechanical claw is arranged on the rotating mechanism.

[0028] Preferably, the rotating mechanism includes a rotating shaft, a first synchronous belt mechanism and a first driving mechanism for driving the first synchronous belt mechanism, the rotating shaft is vertically arranged on the small arm, and the first synchronous belt mechanism includes the first synchronous belt mechanism A synchronous pulley, a second synchronou...

Embodiment 2

[0039] Such as figure 1 , 2As shown, this embodiment provides a multi-joint robot, which includes a horizontally arranged and mutually articulated boom 10 and a forearm 20, a motion unit arranged on the forearm, and a mechanical claw 31 for grabbing parts, The moving unit includes a lifting mechanism 40 , on which the mechanical gripper 31 is arranged, and can move up and down along with the lifting mechanism 40 .

[0040] In this embodiment, one end of the boom 10 is hinged to one end of the small arm 20 . The mechanical claw 31 can specifically adopt an air claw. The air gripper is connected with the pneumatic mechanism, and the air gripper can grasp the workpiece or loosen the workpiece according to the control of the pneumatic mechanism.

[0041] Preferably, if long-distance transmission is to be realized, the length of the large arm and / or the forearm can be increased, or the number of the forearm can be increased, that is, the number of the forearm can be multiple, an...

Abstract

The invention provides a multi-joint robot, which comprises a large arm, a small arm, a movement unit and a gripper, wherein the large arm and the small arm are horizontally arranged and are mutually hinged, the movement unit is arranged on the small arm and comprises a lifting mechanism, and the gripper is used for gripping parts, is arranged on the lifting mechanism and can make lifting movement along with the lifting mechanism. The multi-joint robot is small and exquisite and flexible in tail end, compact in structure and good in control performance.

Description

technical field [0001] The invention relates to a multi-joint robot. Background technique [0002] Industrial robots have been widely used in production sites and can complete tasks such as welding, handling, assembly, and cutting. The application of industrial robots is of great significance to improving production efficiency and product quality, improving the working environment, ensuring human safety, and reducing production costs. [0003] At present, in the vast majority of small parts processing occasions, operations such as loading and unloading, assembly, and palletizing are still mainly done manually. Manually completing the above operations has disadvantages such as low efficiency, high labor intensity, and poor safety. In addition, for some workpieces with narrow processing space, if industrial robots are used for operations, the end of the robot is required to be able to extend into the processing area, so as to facilitate the operation, which requires the end o...
