Abstract
The utility model discloses an automatic sampling device. The automatic sampling device mainly comprises five parts, namely a sample tray, a turret base, a control drive mechanism, an execution sampling analysis mechanism and a control panel, and the automatic sampling device is characterized in that the control drive mechanism and the execution sampling analysis mechanism are placed on the turret base; and one side of the turret base is respectively provided with the control panel and the sample tray. The automatic sampling device provided by the utility model has the advantages that the automaticity is high, the control accuracy is high, the volume is small and the structure is compact, the programmable control is realized, the use is flexible and convenient, is safe and reliable and can be extensively used for detection of different liquid solvents of different departments such as chemical industry and medicine.
Description
Technical field
The utility model is a kind of automatic sampling apparatus, belongs to liquid-detecting, and the intellectual analysis that can be used for various poisonous and harmful solution detects, and can be applicable to the every field such as chemical industry, medicament, chemical defence detection.
Background technology
At present, the liquid detecting sampling device of selling on the home market has a variety of, be mainly used in the solution chemistry context of detection such as medical treatment, chemical industry, medicament, but most of automaticity is not high, complicated operation is loaded down with trivial details, and particularly for detecting some poisonous and hazardous dangerous biological or chemical product, danger is very large, there is security incident hidden danger, can not satisfies the safe operation request for utilization of some Code in Hazardous Special Locations.
Summary of the invention
The purpose of this utility model is to detect all deficiencies of sampling device in order to overcome traditional liquid, provides a kind of automaticity high, flexible, and is accurately highly sensitive, has again data to process and the strong liquid detecting sampling device of Presentation Function.
The technical scheme that the utility model adopts is: a kind of automatic sampling apparatus, mainly formed by sample tray, capstan head base, control driving mechanism, execution sampling analysis mechanism and control panel, it is characterized in that controlling driving mechanism and be placed on the capstan head base with execution sampling analysis mechanism, capstan head base one side is settled respectively control panel and sample tray.Wherein carry out sampling analysis mechanism and formed by 3 stepper motors, realize sequential, angle and displacement control by control driving circuit PLC and main control unit.Can place 15 test agents bottles on the sample tray.Carry out sampling analysis mechanism and formed by 3 stepper motors and accessory, electronic circuit, and cooperate feedback coder, the sequential andlogic control that implementation procedure is strict and accurate angle and the control of accurate displacement amount.Basic controlling comprises: the bottle of system initial state, sample number location, chromatogram injection port are located, sample is quantitative, sample introduction is injected, wash pin etc.Because it is the electronics following control system of core that this automatic sampling apparatus adopts PLC (programmable logic controller (PLC)), 15 sample positions, machine top formula (rotary type tower), modular mentality of designing, system comprises five parts: mechanical structure system, actuator system, control drive circuit system, PLC control system and CPU main control end.The PLC control system realizes the elemental motion control of sequential and topworks, and the CPU main control end is finished parameter setting, workflow and data and processed and control, and PLC control system and CPU master control terminal are set up with PORT COM and connected.Because this device adopts loop control theory, can realize the Automatic Control function, the feedback coder pick-up unit directly is housed on the stepper motor, the actual rotational angle that detects is fed back in the comparer of numerical control device, compare with the former instruction corner value of input, do to replenish displacement with the difference control assembly after relatively, until that difference just stops when eliminating is mobile, reach pinpoint control system.
The utility model beneficial effect is, this automatic sampling apparatus automaticity is high, control accuracy is high, safe and reliable, volume is little and compact conformation, can realize control able to programme, flexible and convenient to use, the various liquid fluxs that can be widely applied to the various departments such as chemical industry, medicine, chemical defence detect.
