Abstract

The invention discloses a method for automatically dispensing liquid medicine, which relates to a liquid medicine dispensing device, which includes a PLC controller, a three-dimensional motion machine equipped with mechanical claws, a mother liquor workbench for storing several mother liquor bottles, and a syringe 1. Measuring workbench and rack for storing sample cups; under the sample cups, there is a measuring weight sensor, and the mouth of the mother liquid bottle is screwed to the syringe. The syringe includes the syringe body and the piston. Clamp and rotate the syringe body and extract the plunger. There are four main steps in the working process of the device: calling out, extracting, injecting, and sending back. Different preparation processes require mechanical claws to help realize the movement of the syringe between the mother solution bottle and the sample cup. This process is mainly set by the PLC controller. . The invention replaces manual operation, can improve work efficiency, reduce labor intensity, and ensure the smooth development of research work, and is applicable to various medical and chemical enterprises.

Description

technical field

[0001] The invention relates to the technical field of medicine dispensing systems, in particular to an automatic liquid medicine dispensing method. Background technique

[0002] The drug dispensing system is a regular work in universities, hospitals, scientific research institutes, laboratories, laboratory work and other places. Especially in the teaching and scientific research work in the chemical industry, laboratories, research rooms, etc., will use a large number of chemical reagents. The precision is high, but it is also limited by various conditions such as orderliness and timeliness. Reagent configuration is a very cumbersome and time-consuming work, especially for research reagent configuration and formula, which often requires many configuration tests. When there are a large number of reagents (dozens of types), manual operation and record It is time-consuming and labor-intensive, requiring a large number of reagent bottles to be searched, and th...
