Problems solved by technology

[0002] In the current field of assembly robots, most assembly robots can only carry a small load. If the load becomes larger, it will cause problems such as inflexible movement and a decrease in structural rigidity, which will greatly reduce its operating reliability; at the same time, the existing Spherical robots, cylindrical robots, and multi-joint robots have relatively small operating ranges, which are difficult to meet the needs of modern assembly manufacturing industries. Cartesian coordinate robots have a large operating range, but they take up a lot of factory space, so we need a A high-performance assembly robot that can realize large loads, high-precision operations, and a large operating range

Embodiment Construction

[0032] As shown in the figure: the high-precision and large-load assembly robot of this embodiment includes a base assembly 1, an arm assembly, an end effector 2 and a control system. The arm assembly includes a forearm 3, a rear arm 4 and a forearm 3 respectively. A compound joint 5 that is articulated with the rear arm 4 and can realize the lateral swing, pitch and revolution motion of the forearm 3. The end effector 2 is connected to the forearm 3, and the rear arm 4 is arranged in cooperation with the base assembly 1 in a manner that can be turned up and down. The rear arm 4 can also rotate in a vertical plane;

[0033] The compound joint 5 includes a joint housing 6 and a motion drive assembly. The motion drive assembly includes a main drive device, a side swing motion transmission assembly, a pitch motion transmission assembly and an epicyclic motion transmission assembly. The main drive device includes a main drive motor 7 and a main drive The gear transmission pair, th...

Abstract

The invention discloses a high-precision heavy-load assembly robot which comprises a base assembly, a tail end executor, a control system, a front arm, a rear arm and a composite joint, wherein the composite joint is hinged to the front arm and the rear arm respectively to achieve lateral swing, pitch movement and turning movement of the front arm. In the composite joint, a main drive motor is a two-way coaxial output motor, a driving gear of a main drive gear transmission pair is in transmission connection with an output shaft on one side of the main drive motor, a pitch movement transmission assembly is in transmission fit with an output shaft on the other side of the main drive motor in a disengagement and engagement mode, and a lateral swing movement transmission assembly and a turning movement transmission assembly are both in transmission fit with a driven gear of the main drive gear transmission pair in a disengagement and engagement mode. By means of the robot, high precision and heavy load can be achieved, besides, the composite joint can achieve movement of the front arm in the three degrees of freedom of lateral swing, pitch and turning, the rear arm can ascend and descend in a circulating mode and rotate in a vertical plane, and the assembly robot has a wide work range.

Description

technical field [0001] The invention relates to a robot, in particular to a high-precision and large-load assembly robot. Background technique [0002] In the current field of assembly robots, most assembly robots can only carry a small load. If the load becomes larger, it will cause problems such as inflexible movement and a decrease in structural rigidity, which will greatly reduce its operating reliability; at the same time, the existing Spherical robots, cylindrical robots, and multi-joint robots have relatively small operating ranges, which are difficult to meet the needs of modern assembly manufacturing industries. Cartesian coordinate robots have a large operating range, but they take up a lot of factory space, so we need a It is a high-performance assembly robot that can realize large loads, high-precision operations, and has a large operating range. Contents of the invention [0003] In view of this, the present invention provides a high-precision and large-load ...
