Sample storing and taking mechanical arm device

Abstract

The invention discloses a sample storing and taking mechanical arm device. The sample storing and taking mechanical arm device comprises a mechanical arm and a driving device, wherein the driving device is used for driving the mechanical arm to move at a bottle storage station; the mechanical arm comprises a first storing and taking assembly and a sample bottle bin assembly; the sample bottle binassembly is provided with a bin shifting driving part and a plurality of sample bottle bins; and the bin shifting driving part drives the multiple sample bottle bins to move between the first storingand taking assembly and the bottle storage station in sequence so as to be used for sequentially taking a plurality of sample bottles stored at the bottle storage station into the sample bottle bins through the first storing and taking assembly or sequentially storing the sample bottles in the multiple sample bottle cabins into a bottle storage station. The sample storing and taking mechanical armdevice has the advantages that the structure is simple and compact, the operation is convenient and flexible, the sample storing and taking time is short, and the taking and conveying process is safeand efficient.

Description

technical field [0001] The invention mainly relates to the field of coal sample storage and retrieval equipment, in particular to a sample storage and sampling manipulator. Background technique [0002] For the sampling, sample preparation, and testing of material (such as ore, coal) samples, each country has mandatory standards, and the sampling and processing of samples must be carried out in accordance with the standards. The principle of sample sampling, sample preparation, and testing work process is to gradually reduce the particle size and quality of the collected samples without destroying the representativeness of the sample, until it meets the particle size and quality of the sample in the laboratory test ( Weight) accuracy requirements, and then carry out relevant laboratory analysis on the samples that meet the requirements. [0003] For example, taking coal sampling as an example, it is actually a sampling and analysis process. The purpose of coal sampling and ...

Problems solved by technology

The defects in this situation are: 1) The sampling time is too long, and the manipulator needs to move back and forth to empty the storage space and store the bottles. Assuming that it takes 40 seconds to take a sample bottle and store it, it takes 5 minutes for 7 sample bottles Left and right; 2) The manipulator moves frequently, which may affect the positioning accuracy and service life

3) The database operation is too frequent, because the information of each vial in the vial warehouse is stored in an independent data table. Vial storage algorithm is too complex
