Technical Field
The utility model relates to an automatic sample injector, in particular to advance a kind dish protection mechanism among automatic sample injector.
Background
With the development of the chromatography industry, the automatic sample feeding mode is more and more common, and the use frequency of the automatic sample feeder is improved. Along with the successive release of various manufacturers, the competition of the automatic sample injector is more and more intense, the performance of the sample injector is gradually improved, and the sample injection precision, the sample injection repeatability, the cross contamination and the like are obviously improved.
The rotating tray is one of the trays of the automatic sample injector, and is arranged in the automatic sample injector, so that the position of the sample tray is changed in a rotating manner, and the sample bottles placed in the sample injection tray are convenient to replace.
When the sample bottles in the sample tray are replaced, the rotating tray is firstly rotated to enable the corresponding sample tray to be close to the outlet, and then the sample tray is drawn out from the rotating tray to replace the sample bottles. However, in this process, the operator may make a mistake, and the button for replacing the tray is pressed when the sample injection tray is not reset, which may cause the sample injection tray to violently impact the outlet, resulting in damage to the auto-sampler.
SUMMERY OF THE UTILITY MODEL
In order to solve the defects in the prior art, the utility model aims to provide a sample feeding disk protection mechanism in an automatic sample feeder, the mechanism can effectively prevent the condition that a rotary tray can rotate under the condition that the sample feeding disk does not reset, and the automatic sample feeder is prevented from being damaged.
The utility model provides a technical scheme that its technical problem adopted does: a sample injection disc protection mechanism in an automatic sample injector comprises a shell, wherein a sample injection disc of the automatic sample injector is connected to the inside of the shell through a rotary tray, and one side of the shell is provided with an opening; a driving unit for driving the rotary tray to rotate is further installed in the shell;
a first detection unit is embedded at the bottom of the sample feeding disc, and a second detection unit matched with the first detection unit is arranged at the bottom of the opening;
the driving unit is connected with a control system of the automatic sample injector;
the first detection unit or the second detection unit is connected with a control system of the automatic sample injector.
Optionally, the first detecting unit is a magnet, and the second detecting unit is a hall sensor;
and the Hall sensor is connected with a control system of the automatic sample injector.
Optionally, a shallow groove adapted to the sample injection tray is arranged on the bottom side of the opening.
Adopt above-mentioned technical scheme, the utility model discloses can effectually prevent the condition that rotatory tray can be rotatory under the condition that advances the sample tray and not reset, prevent to destroy the auto-sampler.

Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and are not limiting of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
As shown in fig. 1 and 2, the utility model discloses a advance kind dish protection mechanism in automatic sample injector, this advance kind dish protection mechanism locate in the casing 1 of automatic sample injector, advance kind dish 2 of automatic sample injector then connects in the inside of casing 1 through rotatory tray 3, make advance kind dish 2 can be at 1 internal rotations of casing, and then realize changing the dish. Normally, in one rotating tray 3, there are two sample trays 2, and the two sample trays 2 are both slidably connected to the top surface of the rotating tray 3, and when one of the sample trays 3 is rotated to the position of the opening 4 on one side of the housing 1, the corresponding sample tray 2 can be manually drawn out. However, in the conventional automatic sampler, after the sample disk 2 is drawn out, the operator sometimes forgets that the sample disk 2 has been drawn out, and directly presses the disk changing button, and at this time, the rotating tray 3 rotates, and the drawn sample disk 2 collides with the opening 4 of the housing 1, so that the sample disk 2 is damaged.
Therefore, in the utility model discloses in, at the first detecting element 5 of the bottom embedding of advancing kind dish 2, the bottom position embedding of opening 4 has the second detecting element 6 with the adaptation of first detecting element 5. Through the matching of the first detection unit 5 and the second detection unit 6, the control system of the automatic sampler acquires the position information of the sample tray 2, namely when the first detection unit 5 and the second detection unit 6 are matched, the sample tray 2 is in a drawing-out state, at the moment, a tray changing button is pressed, and the control system does not execute tray changing operation; when the first detection unit 5 and the second detection unit 6 are not matched, the situation that the sample tray 2 is in a reset state is indicated, and at the moment, the tray changing button is pressed, and the control system executes the tray changing operation.
Specifically, in an embodiment of the present invention, the first detecting unit 5 may be a magnet, and the second detecting unit 6 may be a hall sensor, so that the control system acquires the position information of the sample tray 2 through the cooperation between the magnet and the hall sensor.
The utility model discloses in, at the opening 4 position of casing 1, offer the shallow slot 7 that is used for with advance kind dish 2 adaptations, when taking out advance kind dish 2, when only advance kind dish 2 and shallow slot 7 align, advance kind dish 2 and could be taken out to this sample introduction precision of guaranteeing after trading the dish. At this time, the hall sensor is embedded in the shallow groove 7.
Furthermore, in the present invention, it should be known that a driving unit for driving the rotating tray 3 to rotate is further installed in the housing 1 of the auto-sampler, the driving unit is connected with the control system of the auto-sampler, and the driving unit is prior art and is not described in detail in this specification.
The above description is only a preferred embodiment of the application and is illustrative of the principles of the technology employed. It will be understood by those skilled in the art that the scope of the present invention is not limited to the specific combination of the above-mentioned features, but also covers other embodiments formed by any combination of the above-mentioned features or their equivalents without departing from the spirit of the present invention. For example, the above features may be replaced with (but not limited to) features having similar functions disclosed in the present application.
Besides the technical features described in the specification, other technical features are known to those skilled in the art, and further description of the other technical features is omitted here in order to highlight the innovative features of the present invention.
