High-load two-axis robot

Abstract

The invention discloses a high-load two-axis robot which comprises a stand column, a Z-axis sliding plate, an X-axis cantilever and an X-axis sliding plate. Fixing feet are arranged at the bottom end of the stand column, a Z-axis frame plate is arranged at the top end of the stand column, a Z-axis frame plate rail is connected to a Z-axis sliding plate, and the Z-axis frame plate is provided with a Z-axis servo motor which is connected to the Z-axis sliding plate in a driving mode; the Z-axis sliding plate is connected to an X-axis cantilever, an X-axis sliding plate rail is connected to the X-axis cantilever, the X-axis cantilever is provided with an X-axis servo motor, and the X-axis servo motor is in driving connection with the X-axis sliding plate through a transmission mechanism; and the left stroke and the right stroke of the X axis can be the same through cooperation of a half-stroke synchronous belt and a whole-stroke synchronous belt, a speed reducer is directly connected with the synchronous belts, the speed ratio is reduced, and the speed increasing efficiency is improved. The transmission function is achieved through the transmission mechanism and the speed reducer, the situation that the load of the X-axis cantilever directly acts on the X-axis servo motor is avoided, the X-axis servo motor only plays a driving role, and therefore the large-load driving capacity of the whole structure can be improved.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a high-load two-axis robot. Background technique [0002] The workpiece in production is usually transported by a handling robot when it is transferred between stations. As the precision of the workpiece increases, the accuracy of the handling also increases; at the same time, in order to improve the stability of the handling, the handling robot is carrying out There are high requirements on the change rate of the moving speed of the workpiece during the action; at present, the handling robot mainly has defects such as slow speed increase, low precision, and small load. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a high-load two-axis robot that can effectively improve the handling accuracy and increase the speed-up speed. [0004] Technical solution: In order to achieve the a...
