Intelligent sample storage cabinet system

Abstract

The invention discloses an intelligent sample storage cabinet system. The system comprises a sample storage unit for storing samples, a sample storage/taking movement unit for shifting the samples, and an intelligent control unit; the sample storage unit includes multiple storage bins arranged in an array form; the sample storage/taking movement unit includes a pneumatic manipulator mechanism; the pneumatic manipulator mechanism is provided with a storage cavity and a negative-pressure production component; and after an opening end of the storage cavity is tightly connected with opening ends of the storage bins, the negative-pressure production component extracts air in the storage cavity and the storage bins to form vacuum negative pressure so as to suck the samples in the storage bins to the storage cavity. The system has the advantages of high space utilization rate, high intelligent modular degree, capability of synchronously storing and taking one or more samples and safe and efficient sample storage and taking.

Description

technical field [0001] The invention mainly relates to equipment for collecting and processing material samples, and in particular to an intelligent sample storage and inspection cabinet system. 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...

AI Technical Summary

Problems solved by technology

The existing sample storage cabinet system uses a rotatable and movable clamping manipulator for accessing sample bottles. The layout is that the manipulator is set in the middle, and the storage positions are set on both sides of the manipulator. Only one sample (sample bottle) can be stored in each storage position, so that the manipulator can smoothly grab the sample (sample bottle) in the storage position; therefore, this method greatly limits the setting of the storage position, making each The storage bin can only store one sample (sample bottle), which ultimately leads to low storage space utilization and low storage quantity per unit area

At the same time, since the manipulator needs to enter the storage bin to hold the sample (sample bottle), it is necessary to reserve a clamping space in the storage bin, which also indirectly reduces the number of samples stored in the sample storage cabinet system

[0007] 2. The storage method is single, and the requirements for samples (sample bottles) are high, and different types of samples (sample bottles) cannot be stored

Because if samples (sample bottles) of different sizes are stored, it will directly affect the precise positioning of the manipulator, which will cause the manipulator to be unable to pick up samples (sample bottles) of different types, and even cause the samples (sample bottles) to fall. drop and sample loss, which is a very serious matter for sampling and preparation work that requires extremely high precision and efficiency

[0008] 3. There is a risk of dropping and losing samples during storage and transportation

The method of clamping and sampling by the manipulator makes the sample (sample bottle) unsupported and unprotected during the moving process. Dropping samples (vials) There is a risk of falling during movement

And the clamping force determines the clamping weight, which also makes the manipulator less adaptable to the sample (sample bottle) weight requirements

[0009] 4. Low work efficiency and high cost of use

Since only one sample (sample bottle) can be stored in one storage compartment of the sample storage and inspection device, and the manipulator device can only grab one sample (sample bottle) for a single sampling, which greatly reduces the work efficiency; and is subject to different specifications , The shape of the sample (sample bottle) is limited, and different manipulators need to be designed to meet the needs of gripping and moving, which increases the work cost

[0010] 5. Low degree of intelligence and modularization

Some existing sample storage cabinet systems are low in intelligence, cannot be smoothly connected with other external devices, and cannot have the functions of automatic sample in and out, manual sample in and out, and waste sample processing at the same time; and some existing sample storage cabinet systems are modularized The degree is low, and it is impossible to increase or decrease flexible functional modules according to the actual situation of customers, which cannot meet the actual needs of customers well, increases the cost of use, and reduces market competitiveness
