Embodiment Construction

[0044] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0045] like Figure 1 ~ Figure 3 As shown, the present invention provides a method for controlling the robot to follow the movement of the conveyor belt, which is described in conjunction with the structure, and specifically includes the following steps:

[0046] Step a, obtain the poses p0 (x0, y0, z0, w0, p0, r0), p1 (x1, y1, z1, w1, p1, r1), the first marking point 26 can be completely overlapped to the second marking point 27 by the movement of the conveyor belt 21, then:

[0047] The motion direction vector is (x1-x0, y1-y0, z1-z0), and the direction is figure 2 in the direction of the arrow;

[0048] The result after unitization is: vector_belt(belt_dx,belt_dy,belt_dz);

[0049]Step b, in the moving state of the conveyor belt 21, measure the time difference time_io of the first IO sensor 29 and the second IO sensor 30 triggered by the ...

Abstract

The invention discloses a method and device for controlling robot to move with conveyor belt, wherein the device comprises a conveyor belt direction calculating unit, a conveyor belt speed calculating unit, a track programming unit and a following control unit. According to the invention, in conveyor belt motion state, the average movement velocity of the conveyor belt can be obtained based on time difference calculation, there are no direction requirement for the conveyor belt relative to a robot, in the stop state of the conveyor belt, the robot can perform track programming on a component of technical operation, an operation mode that the conveyor belt and the robot are completely staggered is improved, a plurality of points of the component of the technical operation can follow the conveyor belt to move and work, the limitation of work application range is small, the device is simple and easy to use, the device is suitable for flow line production of robot and conveyor belt, the technical operation time is helped to shorten, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the application of robots, in particular to a method and device for controlling the movement of a robot following a conveyor belt. Background technique [0002] In the application of robots, conveyor belts are often used to transport process object parts. These parts are often in batches and have the same operation requirements. In spraying, gluing and other industries, robots are often required to work on the process trajectory of these parts. [0003] Existing technology has following defect: [0004] (1) After the conveyor belt transports the part in place and stops, the robot operates on the process trajectory of the part until the operation is completed, then starts the conveyor belt to transport the next part in place and stops, and then the robot performs operations on the process trajectory of the part, and so on. The staggered movement of the conveyor belt and the robot results in a long time-consuming operation per ...
