Calibration device and method for automatic fixing and visual pose adjustment of water meters

Abstract

The invention discloses a calibration device and method for automatic fixing and visual pose adjustment of water meters. The device comprises parallel guide rails, a sliding mechanism, a water meter clamping mechanism and an air cylinder pressing mechanism, wherein the sliding mechanism, the water meter clamping mechanism and the air cylinder pressing mechanism are arranged on the parallel guide rails; the water meters are clamped by the water meter clamping mechanism and placed on the sliding mechanism, and then the air cylinder pressing mechanism drives the sliding mechanism to move along the parallel guide rails; a standard image is shot, a mechanical arm moves above the to-be-detected water meters, the to-be-detected water meters are grabbed, rotation is conducted again according to visions so that the posture of each to-be-detected water meter can be matched with a standard posture, the to-be-detected water meters are vertically placed between two connecting frames through the mechanical arm and placed in a half-moon-shaped lifting structure, an air cylinder barrel works so that an inlet and an outlet of each water meter and horizontal through holes of the connecting frames can be tightly pressed and communicated, and a fluid passage is formed to calibrate the water meter. Full automation of calibration of the water meters is achieved, manual water meter feeding is replaced, manual operation is not needed in the whole process of pipeline connection, feeding and calibration, manpower is saved, and the water meter calibration efficiency is improved.

Description

technical field [0001] The invention relates to the field of water meter verification, in particular to a verification device and method for automatic fixing of a water meter and adjustment of visual pose. Background technique [0002] Due to the relatively high accuracy required for water meter verification, in the quality inspection institute, before the water meter is verified, the water meter is placed on the verification platform manually, and the connection of the water meter verification pipe and the fixing of the water meter are also manually completed. These operations before the verification are all done manually, and a fully automatic verification in the true sense has not been realized. In this case, the time cost is high and the efficiency of water meter verification is not high. In order to improve the efficiency of water meter verification and realize the automatic verification of water meters, the above system is designed. Contents of the invention [0003...
