Mass spectrometer is divided into isotope mass spectrometer, inorganic mass spectrometer and organic mass spectrometer according to the application range. According to the resolution, it is divided into high resolution, medium resolution and low resolution mass spectrometer. According to the working principle, it is divided into static instrument and dynamic instrument. And the development of organic mass spectrometer is very important in the use of various combined instruments (gas chromatography, liquid chromatography, thermal analysis, etc.).

[0003] At present, after the corresponding sample is transported to each sampling bottle in the sample frame through the sampling mechanism, the corresponding sampling bottle in the sample frame needs to be sampled into the mass spectrometer detection mechanism in turn, and in the sampling process, there are usually two ways of manual sampling and mechanical automatic sampling, wherein the advantage of manual sampling is that the grabbing area is small, and the corresponding sampling bottle can be selected in a small space more accurately, but the efficiency of manual sampling is slow, and it is not suitable for long-term work, and the advantage of mechanical automatic sampling is high efficiency, and the sampling operation can be continuously carried out, but the mechanical gripper has a large structure, so that the sampling bottles in the sample frame need to have a certain spacing to ensure that the mechanical hand does not interfere with the adjacent sampling bottles, and this also leads to that the number of sampling bottles that can be accommodated in the sample frame is small, it is difficult to store more sampling bottles at the same time, and then the sampling and sampling efficiency is affected. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at providing a kind of mass spectrometer sampling device that improves the receiving volume of sampling bottle of mass spectrometer sample frame, and the specified sampling bottle therein can be conveniently extracted.

[0005] To solve the above technical problems, the utility model provides a kind of mass spectrometer sampling device, including sample frame, the array opening in the sample frame in a plurality of storage slots, lift and set the bottom plate of storage slot bottom, to make sampling bottle when being placed in storage slot, sampling bottle is supported on the bottom plate;The first drive section and the second drive section are movably arranged on the bottom of the sample frame, and the first drive section and the second drive section are staggered, and the driving part is movably arranged on the first drive section and the second drive section, so that the driving part is located at the staggered point of the first drive section and the second drive section, and the driving part and the bottom plate are repulsive.

[0006] Further, the opening of the storage slot is detachably provided with a positioning ring along the circumference, the positioning ring and the bottom plate are connected by a telescopic tube, and the telescopic tube is provided with an elastic element.

[0007] Furthermore, the base plate has a pad on the side near the sampling bottle.

[0008] Furthermore, the base plate has a first magnetic element on the side near the driving component, and the driving component has a second magnetic element on the side near the base plate. When the second magnetic element is activated, the first magnetic element and the second magnetic element repel each other.

[0009] Furthermore, the driving component is provided with a first limiting ring and a second limiting ring along the circumferential direction. The first limiting ring is in movable engagement with the first driving segment, and the second limiting ring is in movable engagement with the second driving segment.

[0010] Furthermore, a through hole is provided at the bottom of the storage compartment, and the inner diameter of the through hole is smaller than the outer diameter of the base plate.

[0012] The beneficial effects of this utility model are as follows: Each sampling bottle is placed in the storage slot of the sample frame, and the sample is transported to the corresponding sampling bottle by the front sampling mechanism. When a sampling bottle needs to be selected for injection, the first drive section and the second drive section are activated simultaneously. Since the drive component is located at the intersection of the first drive section and the second drive section, the coordinated movement of the first drive section and the second drive section can move the drive component horizontally to the lower side of any storage slot. At this time, the drive component is moved to the lower side of the storage slot where the sampling bottle to be injected is located. Through the mutual repulsion between the drive component and the bottom plate, the bottom plate pushes the sampling bottle upward. Since the sampling bottle to be injected is higher than the other sampling bottles, the robot arm can smoothly grasp the sampling bottle without having to set the spacing between adjacent sampling bottles. This solution can greatly increase the number of sampling bottles that can be contained in the sample frame while ensuring stable grasping of the sampling bottles. Attached Figure Description

[0022] like Figures 1-5 The present invention provides a mass spectrometer sample introduction device, including a sample frame 1, a plurality of placement slots 2 arrayed in the sample frame 1, and a base plate 3 that is lifted and lowered at the bottom of the placement slots 2 so that when the sampling bottle is placed in the placement slot 2, the sampling bottle is supported on the base plate 3; the bottom of the sample frame 1 is movably provided with a first driving section 4 and a second driving section 5, and the first driving section 4 and the second driving section 5 are staggered; a driving component 6 is movably provided on the first driving section 4 and the second driving section 5 so that the driving component 6 is located at the intersection of the first driving section 4 and the second driving section 5, and the driving component 6 and the base plate 3 are mutually exclusive.

[0023] Each sampling bottle is placed in the storage slot 2 of the sample frame 1, and the sample is transported to the corresponding sampling bottle by the front sampling mechanism. When a sampling bottle needs to be selected for injection, the first drive section 4 and the second drive section 5 are activated simultaneously for movement. Since the drive component 6 is located at the intersection of the first drive section 4 and the second drive section 5, the coordinated movement of the first drive section 4 and the second drive section 5 can move the drive component 6 horizontally to the lower side of any storage slot 2. At this time, the drive component 6 is moved to the lower side of the storage slot 2 where the sampling bottle to be injected is located. Through the mutual repulsion between the drive component 6 and the base plate 3, the base plate 3 pushes the sampling bottle upward. Since the sampling bottle to be injected is higher than the other sampling bottles, the robot can smoothly grasp the sampling bottle without the need to specially set the spacing between two adjacent sampling bottles. This allows the solution to greatly increase the number of sampling bottles that the sample frame 1 can accommodate while ensuring stable grasping of the sampling bottles.

[0024] In one embodiment of this solution, the first drive segment 4 and the second drive segment 5 are arranged in a cross-shaped pattern, and the first drive segment 4 is located above the second drive segment 5 to avoid interference when the two move.

[0025] Preferably, a positioning ring 7 is detachably provided circumferentially at the opening of the storage slot 2. The positioning ring 7 is connected to the base plate 3 through a telescopic tube 8, and the telescopic tube 8 has an elastic element 9 inside.

[0026] Specifically, the positioning ring 7 is connected to the opening of the storage slot 2, and the elastic element 9 keeps the telescopic tube 8 in an extended state, so that the telescopic tube 8 pushes the bottom plate 3 to the bottom of the storage slot 2. This allows the sampling bottle to be placed at the bottom of the storage slot 2 when it is placed in the storage slot 2, avoiding the sampling bottle from protruding directly and improving the stability when grabbing the designated sampling bottle later.

[0027] Among them, the elastic element 9 adopts a spring structure.

[0028] In one embodiment of this solution, the positioning ring 7 can be connected to the opening of the storage slot 2 by means of magnetic attraction, thread, etc., so as to facilitate replacement.

[0029] Preferably, the base plate 3 has a pad 10 on the side near the sampling bottle.

[0030] Specifically, when the sampling bottle is placed in the storage slot 2, the bottom of the sampling bottle is protected and shock-absorbing by the soft pad 10, thereby ensuring the stability of the sampling bottle during the process of the base plate 3 lifting the sampling bottle.

[0031] The cushion 10 is made of rubber material.

[0032] Preferably, the base plate 3 has a first magnetic element 11 on the side near the driving member 6, and the driving member 6 has a second magnetic element 12 on the side near the base plate 3. When the second magnetic element 12 is activated, the first magnetic element 11 and the second magnetic element 12 repel each other.

[0033] Specifically, after the first drive section 4 and the second drive section 5 drive the drive component 6 to move to the lower side of the designated storage slot 2, the second magnetic component 12 is activated to generate magnetic force, which in turn repels the first magnetic component 11, thereby lifting the base plate 3.

[0034] The second magnetic component 12 is an electromagnet structure, the first magnetic component 11 is a magnet structure, and the first magnetic component 11 and the second magnetic component 12 are placed in a magnetically repulsive manner.

[0035] Preferably, the driving member 6 is provided with a first limiting ring 13 and a second limiting ring 14 along the circumferential direction. The first limiting ring 13 is in movable engagement with the first driving segment 4, and the second limiting ring 14 is in movable engagement with the second driving segment 5.

[0036] Specifically, when the first drive segment 4 moves, it drives the drive component 6 to move along the second drive segment 5 through the second limiting ring 14. When the second drive segment 5 moves, it drives the drive component 6 to move along the first drive segment 4 through the first limiting ring 13. This allows the drive segment to be moved and maintained at the intersection of the first drive segment 4 and the second drive segment 5, so as to ensure that the drive component 6 moves accurately to the lower side of the corresponding storage slot 2.

[0037] The first drive section 4 and the second drive section 5 are both provided with moving grooves on their inner sides, and the first limiting ring 13 and the second limiting ring 14 are movably engaged in the moving grooves.

[0038] Preferably, the bottom of the storage slot 2 is provided with a through hole 15, and the inner diameter of the through hole 15 is smaller than the outer diameter of the bottom plate 3.

[0039] Specifically, since the inner diameter of the through hole 15 is smaller than the outer diameter of the base plate 3, the base plate 3 will not slide out of the through hole 15 when pushed by the telescopic tube 8, so as to ensure the stability of the support of the sampling bottle by the base plate 3. At the same time, when multiple sampling bottles need to be quickly removed, they can be temporarily removed manually. At this time, the operator can quickly remove multiple sampling bottles by pushing the position of the through hole 15 with his / her fingers, thereby improving the ease of use of this equipment.

[0040] Preferably, the bottom of the sample frame 1 is provided with first guide rails 16 at both ends of the first drive segment 4, and the first drive segment 4 and the first guide rails 16 are in movable engagement. The bottom of the sample frame 1 is provided with second guide rails 17 at both ends of the second drive segment 5, and the second drive segment 5 and the second guide rails 17 are in movable engagement.

[0041] Specifically, the movement of the first drive segment 4 is restricted by the first guide rail 16, and the movement of the second drive segment 5 is restricted by the second guide rail 17, thereby ensuring the stable movement of the drive component 6.

[0042] The first drive section 4 and the first guide rail 16 can be connected by an electric track, and the second drive section 5 and the second guide rail 17 can be connected by an electric track.

[0043] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
