Description
Technical field
The utility model belongs to Instrumental Analysis field, be specifically used for sending in sample, transmit into analytical instrument or from
The device of sample is exported in analytical instrument, more particularly, to a kind of automatic sampler of anti-sticking pin.
Background technology
Injector is a kind of instrument, by it can by testing sample from an external container insert instrument internal reaction or
In analyzing container, and then do the analysis of next step.It is widely used in oil, chemistry, agriculture chemistry, biochemistry, medical and health,
The fields such as food.
Gas phase molecular absorption spectrometer is a kind of instrument that water analysis is carried out using gas-phase molecular absorption spectrometry method, at present
There are ammonia nitrogen (HJ/T195-2005), kjeldahl nitrogen (HJ/T196-2005), nitrite nitrogen (HJ/T197-2005), nitrate nitrogen
(HJ/T198-2005), total nitrogen (HJ/T199-2005), 6, sulfide (HJ/T200-2005) meet Chinese Ministry of Environmental Protection's standard method
Measure project.Mercury (HJ597-2011) cold-vapour atomic absorption method determine and sulphite, permanganate indices (CODMn), chlorine from
The many indexes such as son, bromide ion, iodide ion, cyanide, sulfur dioxide, nitrogen dioxide can be detected using literature method.
Automatic sampler used in existing gas phase molecular absorption spectrometer is generally collar plate shape or the spindle-type auto injections of XYZ tri-
Device, sample introduction arm drive sample introduction needle, lay sample cell sample disc plane above in the range of move, in specified sample feeding pipe position
Move up and down, sample introduction needle is inserted into sample cell, with pipette samples.Collar plate shape or the spindle-type automatic samplers of XYZ tri-, due to sample introduction needle
Movement be move in three dimensions, must be inserted into sample cell could pipette samples, therefore be transferred to other sample feeding pipes
During position, sample introduction needle must extract sample cell.If without sample introduction needle is extracted into sample cell in advance, sample introduction arm drives sample introduction needle
Planar movement can cause sample introduction needle to be stuck on sample cell, and its mechanical movement can influence the fastening of sample introduction arm and sample introduction needle, cause into
Sample pin is tilted or sample introduction arm movement position misalignment, influences sampling precision.
Utility model content
Utility model purpose：To overcome the deficiencies in the prior art, the utility model provides a kind of auto injection of anti-sticking pin
Device, by combining sensor, the motion control to sample introduction arm is limited, and it is reached that sample introduction needle is complete in the position of ordinate
When extracting on the height of sample cell, it is just allowed to carry out plane motion.
Technical scheme：To achieve the above object, the utility model proposes a kind of anti-sticking pin automatic sampler, it is described enter
Sample arm is vertical with the lifting arm and rotates and is connected, and sample introduction needle, the sample introduction needle and the lifting are connected with the sample introduction arm
Arm is parallel, and the sample introduction arm drives to be provided with the plane motion and vertical movement of the sample introduction needle, the sample introduction arm and mutually interconnected
The sensor and sample introduction arm moving control mechanism connect, the sensor is used for the longitudinal direction seat of plane where sensing the sample introduction arm
Mark, the sample introduction arm moving control mechanism is used for the plane motion for controlling the sample introduction arm, when the sensor detects sample introduction
When the height of the longitudinal coordinate of plane reaches that meet sample introduction needle extracts on the height of sample cell completely where arm, the sample introduction arm
Moving control mechanism just triggers the plane motion of the sample introduction arm；The lifting arm is controlled with lifting arm height limiter and lifting successively
Unit processed is connected, and the elevating movement of the lifting arm is controlled by the elevating control unit.
Preferably, the sensor is any one in optocoupler sensor, gyro sensor or Hall sensor.
Beneficial effect：The utility model is by that by the amount of vertical movement of sample introduction arm or can avoid sample introduction needle and sample cell from occurring
The safe altitude of collision informs sample introduction arm moving control mechanism, thoroughly avoids sample introduction needle and sample cell when colliding, sample introduction
Arm continues to move to possible caused mechanical collision and then causes the possibility of sample introduction needle positioning failure.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Embodiment
The utility model patent is further described below in conjunction with the accompanying drawings.
As shown in figure 1, present embodiments provide a kind of automatic sampler of anti-sticking pin, its mainly include chassis, sample introduction arm,
Lifting arm and elevating control unit, sample introduction arm is vertical with lifting arm and rotates and is connected, and sample introduction needle, sample introduction needle are connected with sample introduction arm
Parallel with lifting arm, sample introduction arm drives the biography that interconnection is provided with the plane motion and vertical movement of sample introduction needle, sample introduction arm
Sensor and sample introduction arm moving control mechanism, sensor are used for the longitudinal coordinate of plane where sensing sample introduction arm, that is, sense sample introduction arm
Vertical movement distance, sample introduction arm moving control mechanism is used to control the plane motion of sample introduction arm, when sensor detects sample introduction
The height (i.e. amount of vertical movement) of the longitudinal coordinate of plane where arm reach meet sample introduction needle extract completely sample cell height it
When upper, sample introduction arm moving control mechanism just triggers the plane motion of sample introduction arm, and otherwise sample introduction arm can not carry out plane motion, can only
It is in vertical motion.Lifting arm is connected with lifting arm height limiter and elevating control unit successively, the elevating movement of lifting arm by
Elevating control unit is controlled.
Sensor can use any one in such as optocoupler sensor, gyro sensor or Hall sensor.
The utility model is by combining sensor, and the motion control to sample introduction arm is limited, and makes it in the position of ordinate
Put when reaching that sample introduction needle is extracted on the height of sample cell completely, just allow its to carry out plane motion, thoroughly avoid sample introduction needle
When being collided with sample cell, sample introduction arm continue to move to may caused by mechanical collision so that cause sample introduction needle positioning failure
May.
Described above is only the preferred embodiment of the utility model patent, it should be pointed out that：For the general of the art
For logical technical staff, on the premise of the utility model patent principle is not departed from, some improvements and modifications can also be made, this
A little improvements and modifications also should be regarded as the protection domain of the utility model patent.
