Problems solved by technology

[0003] Because it is judged by human eyes, there must be errors, and different people have different values ​​of errors, and the same person judges different positions each time, which will inevitably lead to unstable points; for batch equipment, the method of manual judgment Time-consuming and low efficiency; human eyes need to be close to the working area of ​​the robot, and there are certain safety hazards for personnel

Abstract

The embodiment of the invention discloses a position calibration device. The device comprises a connecting piece, a displacement sensor, a first ball head rod, a connecting block and a second ball head rod, wherein the connecting piece is used for being mounted on movable equipment; the displacement sensor is arranged on the connecting piece and is electrically connected with the movable equipment; the first ball head rod is arranged on the connecting piece; the connecting block is arranged on to-be-calibrated workpiece; and the second ball head rod is arranged on the connecting block; a firstball head is arranged at the end, away from the connecting piece, of the first ball head rod, and a second ball head is arranged at the end, away from the connecting block, of the second ball head rod. When the position of the to-be-calibrated workpiece is calibrated, the first ball head is in contact with different positions of the second ball head, the displacement sensor transmits the positioninformation of each touch position detected by the displacement sensor to the movable equipment, so that the movable equipment determines the central position coordinates of the second ball head according to the position information, and the number of the touch positions is at least four.

Description

technical field [0001] The invention relates to the field of position calibration, in particular to a position calibration device. Background technique [0002] Industrial robots are more and more widely used in industrial automation production. The repeatability of the robot itself is very high, but the robot has been unable to achieve high accuracy when looking for the relative coordinates of two points. The existing method is: at the end of the robot Place a pointed object on the workpiece and the object, and make the two pointed points as close as possible to determine the position coordinates of this point by visual inspection, and then use the same method to determine the position coordinates of the other point, through two coordinates. Relative coordinates of two points. [0003] Because it is judged by human eyes, there must be errors, and different people have different values ​​of errors, and the same person judges different positions each time, which will inevita...
