Part weighing and counting method

Abstract

The invention discloses a part weighing and counting method, which comprises the following steps: before and after parts are taken and placed, respectively weighing part storage boxes, comparing the weight difference of two times of weighing with the standard weight of the parts, and calculating the number of taken or placed parts; weighing the part storage box under the gravity center of the partstorage box each time. The influence of gravity center change of the part storage box on the weighing precision can be avoided, and the accuracy of the counting result can be improved.

Description

technical field [0001] The invention relates to a method for weighing and counting components. Background technique [0002] In some fields that require precise control of parts, such as the management of a wide variety of small parts for aircraft in aviation maintenance, the supervision of the number of parts used has always been a difficult problem. In the process of repairing the aircraft, the number of parts should be taken according to the demand, and the staff should not be allowed to take them arbitrarily. The purpose is to prevent the staff from forgetting redundant parts inside the aircraft during the maintenance process, thereby avoiding Unnecessarily huge damage caused by parts to the aircraft when the aircraft is in flight. Therefore, the management of these small parts of aircraft is particularly important, and an automated warehousing and logistics system for parts has been designed accordingly, but there is still a lack of intelligent and accurate management ...

Problems solved by technology

However, the realization of this method has great limitations. It is difficult for the manipulator to accurately grasp parts of different shapes and sizes.

[0003] In view of the above problems, the method of weighing and counting can be used to manage the number of parts, but the traditional weighing and counting platform only realizes the function of weighing and counting, and does not consider the parts storage box in the process of picking up parts. The influence of the change of the center of gravity on the accuracy of the weighing process increases the error of the final count

In the available reports, the document "Research on Intelligent Weighing Counter Based on Single-chip Microcomputer [Master's Dissertation], Tianjin, Tianjin University of Science and Technology, 2012" describes the research on intelligent weighing and counting, but does not consider the change of the center of gravity of the object for the sensor. Influenced by measurement accuracy, it is impossible to realize accurate weighing and counting functions in the scene where parts are picked up in real time

The method of weighing and counting bars given in Chinese patent CN201810093466.9 also does not consider the influence of the change of the center of gravity of the bars on the accuracy of the counting results during the moving process, and accurate counting cannot be achieved for the scene where the center of gravity changes
