A device for double weight transmission and alternate loading

Abstract

The invention discloses a double-weight transmission and alternate loading device, comprising: a main body of the device, including a base and a cover, the cover is installed on the base, and a loading space is formed around the cover and the base; a workbench, The workbench is installed on the base to place the weight to be measured and / or the counterweight; the mass comparator is installed on the base to measure the mass of the weight to be measured; the weight transmission mechanism includes A drive assembly and a transfer arm, the drive assembly is installed on the base, the transfer arm is installed on the drive assembly, the drive assembly can drive the transfer arm to transfer the weight to be measured and / or the counterweight between the workbench and the mass comparator ; Wherein the width of the weight placement part of the transfer arm can meet the requirement that two gram weights are placed side by side along the width direction of the weight placement part, and the groove can realize the automatic centering of the weights, improve the measurement accuracy and transmission of the weights , Detection efficiency.

Description

technical field [0001] The invention relates to the measurement field, and further relates to a double-weight transmission and alternate loading device. Background technique [0002] In order to measure various objects of different masses, the mass standard usually consists of a group of standard weights with the fewest number but which can form any value. Standard weights are usually divided into kilogram group (1-20) kg, gram group (1-50) g ​​and milligram group (1-500) mg, and the combination of weights is usually 5, 3, 2, 1, 5, 2, 2, 1 and 5, 2, 1, 1. Currently, the form of 5, 2, 2, 1 is commonly used in China. [0003] It is understandable that the weight is the standard for measuring the quality of the item. Only when the quality of the weight itself has high accuracy can the quality of the item be measured more accurately. Therefore, it is necessary to calibrate the quality of the weight to ensure Weights have precise masses. [0004] Traditional weights are usuall...

AI Technical Summary

Problems solved by technology

[0005] At present, the overall working time of the traditional weight automatic loading device is relatively long. The gripper of the weight loading device can only grab one weight at a time and enter the mass comparator for weighing. Before entering the mass comparator, it is usually necessary to put the weight The weights are placed on the transfer table, and the gripper of the weight loading device needs to reciprocate to pick and place the weights on the transfer table. The process of picking and placing the weights will consume a lot of time, resulting in low overall efficiency of weight detection.

[0006] In addition, the traditional weight automatic loading device is only for continuous weighing equipment, and cannot be applied to discontinuous weighing equipment

Discontinuous weighing equipment, due to the manual adjustment and balancing mode, can only test weights of the same specification at a time

In addition, due to size limitations, when loading a weight of 1g or less, there is a high requirement for the fork gap of the weight loading device, and the manufacturing cost is relatively high.
