Abstract

The application belongs to automation, robot field, discloses a mechanical arm, and its structure includes: the device comprises a rotatable platform (1), a horizontal telescopic joint (2), a vertical rotating joint (3) and a manipulator (4). Wherein horizontal telescopic joint (2) level is fixed on rotatable platform (1), and rotatable platform (1) can drive horizontal telescopic joint (2) rotatory, and perpendicular rotation festival (3) are connected with horizontal telescopic joint (2), realize the adjustment of horizontal distance through the flexible of horizontal telescopic joint (2), and manipulator (4) are connected with perpendicular rotation festival (3), realize height control under the drive of perpendicular rotation festival (3). Because the horizontal telescopic joint of this application is the level fixed, does not need perpendicular rotation, does not have the required very big power requirement of arm overlength to make price greatly reduced, especially adapted distance range is far away, but the height range is little, snatching of the article on the specific platform.

Description

Mechanical arm

Technical Field

The application belongs to the fields of automation and robots and relates to a mechanical arm.

Background

Along with the maturity of the robot technology and the desire of people to advance daily life to the robot, what can popularize going in daily life is intelligent, can accurately get and put article, low cost's robot more and more receives attention to, and current arm adopts pure joint structure mostly, and longer arm is high to the power requirement, causes the life-span weak point, and the cost is high.

Disclosure of Invention

The utility model aims at providing a be applicable to the horizontal distance far away, the height range is limited, the last arm that is used for article to snatch that is used for of specific platform, finally reaches the purpose that the arm needs less power requirement, and longer life.

The application a robotic arm, its structure includes: rotatable platform (1), horizontal telescopic joint (2), perpendicular rotation festival (3), manipulator (4), rotatable platform (1) drives the arm and rotates at specific horizontal plane, and horizontal telescopic joint (2) increase the horizontal distance that the manipulator can reach, and perpendicular rotation festival (3) can realize snatching the action of lifting behind the article to avoid other article or obstacle when making the removal article, manipulator (4) realize snatching the article.

Preferably, the horizontal telescopic joint (2) of the mechanical arm is multi-joint telescopic.

Preferably, the horizontal telescopic joint (2) of the mechanical arm is horizontally fixed on the rotatable platform (1).

Preferably, the mechanical arm is additionally provided with a rotary joint which rotates perpendicular to the vertical rotary joint (3).

Preferably, the manipulator (4) of the mechanical arm can vertically rotate around the tail end of the vertical rotating joint (3) so as to match the vertical rotation of the vertical rotating joint (3) to keep the manipulator at a certain posture all the time.

Preferably, the mechanical arm is characterized in that a lifting platform is additionally arranged on the mechanical arm so as to increase the adjustable height of the mechanical arm, and the rotatable platform (1) is fixed on the lifting platform.

Preferably, a camera is arranged on a mechanical arm (4) of the mechanical arm so as to accurately position an article to be grabbed.

Drawings

Fig. 1 is a schematic structural diagram of the present application.

The notation in the figure is: 1. a rotatable platform (1); 2. a horizontal expansion joint (2); 3. a vertical rotary joint (3); 4. a manipulator (4).

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. d, in an embodiment of the present application, a robot arm includes: rotatable platform (1), horizontal telescopic joint (2), perpendicular rotation festival (3), manipulator (4), rotatable platform (1) drives the arm and rotates at specific horizontal plane, and horizontal telescopic joint (2) increase the horizontal distance that the manipulator can reach, and perpendicular rotation festival (3) can realize snatching the action of lifting behind the article to avoid other article or obstacle when making the removal article, manipulator (4) realize snatching the article.

When an object needs to be grabbed on a specific platform, the vertical rotating joint (3) rotates upwards, the mechanical arm reaches a certain height, so that the mechanical arm is prevented from touching a barrier in the motion process, then the rotatable platform (1) drives the mechanical arm to rotate to a specific angle on a specific horizontal plane, the horizontal telescopic joint (2) stretches to a specific distance capable of grabbing the object, the vertical rotating joint (3) rotates downwards to the height of the object, the mechanical arm (4) grabs the object, the vertical rotating joint (3) rotates upwards to a certain height, the mechanical arm (4) is driven to move to the target position of the target platform through the stretching of the horizontal telescopic joint (2) and the rotation of the rotatable platform (1), and after the vertical rotating joint (3) rotates downwards to a specific height, the mechanical arm (4) places the object to the target position on the target platform.

It will be evident to those skilled in the art that the present application is not limited to the details of the foregoing illustrative embodiments, and that the present application may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
