This automatic weight calibration device can realize the detection process of various operating specifications such as ABBA and ABA, and can realize the automated operation of weight calibration in accordance with the requirements of JJG 99-2022. Place the standard weight and the tested weight on the two pallets respectively. on the support rod, and then moved to the carrier driven by the lifting mechanism and horizontal movement mechanism, and the support rod with standard weights placed on it enters the containment. In the tank, place the standard weight on the carrier. After the mass comparator obtains the mass data of the standard weight, the supporting rod rises and takes the standard weight away, and then the supporting rod with the tested weight moves to the carrier. , the support rod enters the receiving tank, and the weight to be inspected is placed on the scale pan.

  The mass comparator obtains the quality data of the weight being tested.

In accordance with the requirements of JJG 99-2022 "Weights" calibration regulations, enter the number, grade, specification, correction value and other information of the standard weight into the system, and then enter the inspection unit, calibration number, and accuracy level of the weight to be inspected. , weight number, specification number, number of weights, weight material, quality range, production plant and other information are entered into the system (after the task preparation is completed, the settings can be saved so that you can directly call the load when using it in the future without having to re- (Compiled), after the software is set up, the computer sends instructions. The control machine selects the corresponding accuracy level through software, and sets the standard weights in sequence.
Load the program into the mass comparator, read it after it stabilizes, and pick it up after reading the number. Repeat ABBA2 times or ABA2 times in sequence.
Combination comparison is to compare and measure multiple weights in a certain combination. The accuracy and consistency of the weights are verified by analyzing the results of these combined measurements. This method can more comprehensively examine the weights in different combinations. lower performance. The one-to-one comparison directly compares the weight being verified with the standard weight one by one.
Accurately determine the difference between them to determine whether the weight being checked meets the requirements, so that the specific characteristics of a single weight can be detected in detail situation. Through the comprehensive use of these comparison methods, the automatic calibration of weights can be completed more accurately and reliably, ensuring the accuracy and reliability of the weights.

All detection processes are automatically controlled by the system, which reduces labor intensity, improves the accuracy and efficiency of weight measurement, and avoids errors caused by human factors.
In order to solve practical problems in weight calibration, the laboratory of the Weighing Instrument Institute of Hunan Institute of Metrology and Inspection introduced an automatic weight calibration device. The device consists of a robotic arm, sensors, control system, etc.
The robotic arm can automatically grab and load the weights, accurately placing them on the testing equipment for measurement. Sensors can monitor weights in real time
The eccentric position ensures stable and accurate measurement. The control system can automatically control the movement of the robotic arm according to preset programs and algorithms.
and the operation of testing equipment to realize automatic verification and calibration of weights.
