Industrial robot tool hand elastic calibration positioning device

Abstract

The invention discloses an industrial robot tool hand elastic calibration positioning device which comprises a positioning plate, a calibration head, a controller and a guiding shaft. A positioning block is arranged in the positioning plate, and a first guiding plate is arranged on the side face of the positioning block. A positioning shaft is arranged on the side face of the first guiding plate,and a second guiding plate is mounted in the middle of the positioning shaft. The guiding shaft is arranged on the other side of the positioning shaft, and a spring is arranged outside the guiding shaft. A calibration shaft is arranged on the other side of the guiding shaft, and a displacement sensor is arranged in the calibration shaft. The industrial robot tool hand elastic calibration positioning device has the beneficial effects that distance measurement is conducted on industrial robot tool hand elastic calibration to detect the positioning precision, the positioning precision of an industrial robot tool hand is controlled through distance measurement, meanwhile a suction cup of the tool hand can further be protected, and the service life of the industrial robot tool hand elastic calibration positioning device is prolonged.

Description

technical field [0001] The invention relates to the field of positioning devices, in particular to an elastic calibration positioning device for an industrial robot tool hand. Background technique [0002] With the extensive use of industrial robots in enterprises, enterprises pay more and more attention to the operation technology of robots. During the working process of industrial robots, it is mainly the mutual cooperation of robots, PLCs, and intelligent vision systems, and during the debugging and operation of industrial robot tool hands, the coordinate system of the robot is of great importance. In the current use of equipment, engineers and technicians find that the operation accuracy of the robot in the fixed point device is not high, and the repeat positioning accuracy cannot meet the design requirements, which affects the working state of the robot during operation. Especially in the calibration of the industrial robot coordinate system with suction cup tooling is...

Problems solved by technology

In the current use of equipment, engineers and technicians find that the operation accuracy of the robot in the fixed point device is not high, and the repeat positioning accuracy does not meet the design requirements, which affects the working state of the robot during operation.

Especially in the calibration of the industrial robot coordinate system with suction cup tooling is based on the center point of the suction cup, it is usually impossible to accurately locate. In the process, the exact position cannot be found, resulting in the assembly accuracy not meeting the process requirements, and in severe cases, it will cause equipment damage, and the existing tool hand uses virtual coordinates for positioning when positioning, which easily makes the positioning accuracy of the spatial position inaccurate
