Abstract

The invention discloses a flexible joint and a double-drive gantry rectangular coordinate platform. The flexible joint comprises a first connecting block, a second connecting block, a connecting structure and an offset connecting tool. One end of the first connecting block is connected with one end of the second connecting block through a connecting structure; the whole connecting structure is ina wheel type crossed shape, the other end of the first connecting block is fixedly connected with a first object, the other end of the second connecting block is connected with the offset connecting tool, the offset connecting tool is fixedly connected with a second object, and the connecting position of the second connecting block and the offset connecting tool deviates from the center line of the second object. According to the invention, the joint stress can be effectively buffered, and the accurate detection of the cross beam corner can be realized through the analytical model.

Description

technical field [0001] The invention belongs to the technical field of rectangular coordinate robots, in particular to a flexible joint and a double-drive gantry rectangular coordinate platform. Background technique [0002] combine figure 1 and figure 2 As shown, the joints of the traditional double-drive gantry cartesian platform are rigidly connected by bolts directly at both ends of the beam. By optimizing the controller or proposing a better control algorithm, the synchronization error of the double-drive motor can be reduced and the joints can be reduced. stress, and improve the high-speed, high-acceleration dynamic characteristics and operating stability of the platform. However, this method has high cost and is easily disturbed by factors such as nonlinear friction force of external guide rails, end effector load disturbance, and operating conditions. [0003] Flexible joints have the advantages of no friction, no noise, compact structure, and high transmission a...
