Problems solved by technology

[0008] Most of the traditional robot arms are fixed in shape and type, that is, they are specially designed according to the requirements of users, and can only be applied to a specific environment. If the application scene is changed, the original robot arm will no longer be applicable. In addition, Traditional manipulators have poor flexibility, and there are many specifications of various manipulators, the versatility of parts is poor, and there are problems such as unstable quality and reliability, which cannot meet actual needs

Embodiment 1

[0052] As shown in the figure, a new type of lightweight six-degree-of-freedom collaborative robot arm includes a base 1, a first joint 2, a second joint 3, a third joint 4, a fourth joint 5, a fifth joint 6 and a sixth joint 7;

[0053] The first joint, the second joint, the third joint, and the fourth joint all include a first housing 8, a first motor 9 and a first speed reducer 10, the first speed reducer is fixed in the first housing, and the first speed reducer The output end of the first motor is set outside through the first housing, and the first motor is also fixed in the first housing. The output shaft of the first motor is provided with a first synchronous pulley 11, and the input end of the first reducer is provided with The second synchronous pulley 12, the first synchronous pulley and the second synchronous pulley are connected by a synchronous belt 13, and the first motor controls the output end of the first reducer to rotate;

[0054] Both the fifth joint and t...

Embodiment 2

[0072] A new type of light-duty six-degree-of-freedom collaborative manipulator described in Embodiment 1 is different in that a suction cup assembly 49 can be optionally installed on the sixth joint, and the suction cup assembly includes a mounting plate 50, which is detachably fixed on the On the mechanical arm, a plurality of suction cup structures 51 are arranged on the mounting plate, and the suction cup structures are detachably installed on the mounting plate.

[0073] Further, the number of suction cup structures is four, and the four suction cup structures are arranged on the mounting plate in a 2*2 form.

[0074] Further, the mounting plate is a rectangular plate, and the mounting plate is provided with two first through holes 52 of circular structure, and two second through holes 53 of circular structure are arranged between the first through holes, and the first through holes The aperture is larger than the aperture of the second through hole, the two first through...

Abstract

The invention provides a novel light six-freedom-degree cooperative mechanical arm. The novel light six-freedom-degree cooperative mechanical arm comprises a base and multiple joint bodies; one jointbody is fixed to the base, remaining joint bodies are assembled and formed, each joint body comprises a shell, a motor and a speed reducer, the speed reducers are fixed into the shells, output ends ofthe speed reducers penetrate the shells to be arranged outside, the motors are fixed into the shells, first synchronous belt wheels are arranged on output shafts of the motors, second synchronous belt wheels are arranged on the input ends of the speed reducers, the first synchronous belt wheels and the second synchronous belt wheels are connected through synchronous belts, the motors control theoutput ends of the speed reducers to rotate, the output end of the speed reducer of one joint body can be fixed to a through connection opening of the other joint body. Modular design is achieved, producing and making are easy, use is easy, high load / self weight ratio is achieved, the modular reconfigurable aim is achieved, and reliability is high.

Description

technical field [0001] The invention relates to a mechanical arm, in particular to a novel lightweight six-degree-of-freedom cooperative mechanical arm. Background technique [0002] A robot can generally be understood as: a programmable machine that completes certain operations and mobile operations through an automatic control area. People try to design this kind of machine to have certain functions of imitating humans or animals, and to expand and extend these functions to replace people to work. [0003] Industrial robot (Industrial robot) is an automatic control, reprogrammable, multi-functional, multi-degree-of-freedom operation and is used to carry materials, workpieces or manipulate tools to complete various operations. It can be fixed or mobile. The control function, structural characteristics and autonomy of industrial robots are different, but they must meet three basic requirements: use CPU as the core controller for control, such as industrial control computer...
