Background

Reagent and medicine weighing is an essential important link in the daily detection work of the laboratory, and along with the development of scientific technology, a lot of works in the laboratory realize automation. However, reagent weighing is a very important link in laboratories, and most of the reagents are still weighed by original manual weighing methods. The manual weighing method comprises the following steps: firstly, placing a crucible on a high-precision balance (one-ten-thousandth balance), setting zero, adding a reagent by using a sample spoon, slowing down the speed when the reagent is fast to a target value, adding the reagent a little bit, reading balance data at any time, and judging whether the reagent is qualified; if the product is not qualified, the reagent is required to be added or reduced. The process is repeated for many times, so that the weighing time is long, the operation is complicated, and the quality is unstable (particularly, the sample is easy to absorb moisture).

In order to solve the above technical problems, those skilled in the art have designed various automatic weighing devices, and a representative mechanism is: the device is provided with a storage bin for feeding, a vibrator is used for realizing uninterrupted discharging, a lifting rotary table mechanism is used as a crucible switching mechanism, and a high-precision weighing mechanism is arranged below the crucible switching mechanism. The structure can realize the purpose of automatic weighing, but is limited by the control of the vibration precision of the vibration feeder, the weighing precision can only reach +/-0.0005 g, the weighing speed is more than 80 seconds, and the speed is slower than the manual weighing speed. While most laboratories require weighing accuracy of + -0.0002 g for less than 50 seconds.

And traditional weighing instrument ware has certain requirement to the crucible size that uses when weighing the sample, and not all crucibles all are suitable for, just so need with one set of crucible earlier specially weigh the sample, then transfer the sample of weighing to the user crucible of using in fact again, can appear in this transfer process that there is trace sample adhesion to the crucible inner wall and cause unable whole transfer in the sample of weighing, lead to the actual sample volume of weighing to hang down.
