Industrial robot space pose precision test system

Abstract

The invention discloses an industrial robot space pose precision test system, and belongs to the technical field of industrial robots. The industrial robot space pose precision test system comprises a pose measurement cube assembly, a measurement target, a power supply module, a visual sensor and an operation table. The measurement cube assembly is fixed to the front face of a robot measurement area through bolts. The measurement target is fixed in an X-shaped groove in the surface of a pose measurement cube through a screw, the X-shaped groove is located in the front surface of the pose measurement cube assembly, the total length of the X-shaped groove is 1000 mm, and the requirements of different robot working spaces are met. The power supply module is fixed to the bottom of a base through screws and can supply power to the five measurement targets at the same time; and the visual sensor is fixed to the tail end of a robot and connected with the operation table through a communication cable. The industrial robot space pose precision test system is specially used for testing the space pose precision of the industrial robot, and is convenient to use, high in measurement working efficiency, high in precision and low in cost.

Description

technical field [0001] The invention relates to the technical field of industrial robots, in particular to an industrial robot space pose accuracy test system. Background technique [0002] Spatial pose accuracy is one of the most important performance indicators of industrial robots. At present, the test mainly uses a high-precision laser tracker for measurement, but the cost of the laser tracker is relatively high, the operation is more complicated, and the sensor needs to be purchased to measure the attitude accuracy. Most enterprises do not have the ability to purchase this set of equipment. [0003] At present, most of the test systems only measure the spatial position accuracy of the robot end, but cannot measure the spatial attitude accuracy of the robot end, and cannot fully evaluate the robot's accuracy indicators. In addition, the Chinese patent CN 105865341A provides a method and equipment for testing the attitude change of the robot end, but it can only measure ...

Problems solved by technology

At present, the test mainly uses a high-precision laser tracker for measurement, but the cost of the laser tracker is relatively high, the operation is more complicated, and the measurement of attitude accuracy requires additional sensors. Most companies do not have the ability to purchase this set of equipment

[0003] Most of the current test systems only measure the spatial position accuracy of the robot end, but cannot measure the spatial attitude accuracy of the robot end, and cannot fully evaluate the robot’s accuracy indicators

In addition, the Chinese patent CN 105865341A provides a method and equipment for testing the attitude change of the robot end, but it can only measure the accuracy of one point in the space, while the national standard GB / T 12642-2013 stipulates that five points in the largest test cube of the robot should be points for evaluation

Among the currently disclosed technologies, there is no test system for testing and evaluating the five points
