Description

Technical Field

[0001] This utility model relates to the field of mass spectrometers, and in particular to a mass spectrometer with an adjustable detection head height. Background Technology

[0002] A mass spectrometer is an experimental device used to analyze the mass and composition of substances, and it is widely used in many fields such as chemistry, physics, medicine, biology, and environmental monitoring. Its basic principle is to convert the sample into charged ions and analyze the behavior of these ions in an electromagnetic field.

[0003] In current mass spectrometry, the object to be detected is typically placed on the monitoring stage, and the height-adjustable mass spectrometer is used for monitoring. Although the detection head of the mass spectrometer can be height-adjusted, it still has certain limitations; that is, the position adjustment of existing mass spectrometers is limited to height adjustment, lacking multi-position adjustment detection. In some large samples with a wide detection range, there are components or structures in multiple different positions. Without multi-position adjustment capabilities, the mass spectrometer can only detect the sample at a single vertical height, resulting in some components not being fully analyzed, thus affecting the comprehensiveness of the detection. The only solution is to manually adjust the position of the object to be detected multiple times, which affects the detection efficiency.

[0004] Therefore, a mass spectrometer with an adjustable detection head height is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a mass spectrometer with an adjustable detection head height. By using a lateral position adjustment component in conjunction with a rotation component, the mass spectrometer can be adjusted to multiple positions, thereby enabling the height-adjustable mass spectrometer to fully detect the object being tested.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A mass spectrometer with an adjustable detection head height includes a mass spectrometer stage: a lateral position adjustment component is installed on the upper surface of the mass spectrometer stage, a rotation adjustment component is mounted on the lateral position adjustment component, and a connecting seat is installed on the rotation adjustment component;

[0008] The connecting seat is mounted above the mass spectrometer detection station and has an external casing installed at its end. A linear screw module is installed inside the external casing. The linear screw module is vertically arranged and has a mass spectrometer body mounted on its side. The mass spectrometer body is electrically connected to a mass spectrometer detection head. An opening is provided at the bottom of the external casing for the vertical height adjustment of the mass spectrometer detection head.

[0009] The lateral position adjustment component includes a lateral adjustment platform disposed on the upper surface of the mass spectrometer detection stage. Two linear tracks are vertically arranged on the side of the lateral adjustment platform. The two linear tracks are arranged in parallel and each track has two track sliders that are fitted and slide on it.

[0010] The rotation adjustment assembly includes motor mounts disposed on the sides of the four track sliders, the motor mounts being connected to the four track sliders, and a rotary motor being mounted on the side of the motor mounts;

[0011] A height sensor is installed on the side of the outer casing, and an object scanning camera is installed at the bottom of the outer casing. The height sensor and the object scanning camera are electrically connected to the mass spectrometer body via wires.

[0012] Furthermore, the lateral position adjustment assembly also includes two bearing seats disposed on the side of the lateral adjustment platform, and a threaded screw is rotatably disposed between the two bearing seats.

[0013] Furthermore, the lead screw is externally threaded with a lead screw nut, and the side of the lead screw nut is connected to the motor base.

[0014] Furthermore, a forward and reverse motor is installed on the side of the horizontal adjustment platform, and the end of the threaded screw passes through one of the bearing seats and extends to connect with the output end of the forward and reverse motor.

[0015] Furthermore, a transmission rod is vertically connected to the output end of the rotary motor, and a base plate is installed at the top of the transmission rod. The base plate is located below and connected to the connecting seat.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. In practical use, compared with the traditional single height adjustment, the mass spectrometer body of this application can complete the linear height adjustment in the vertical position through the drive control of the linear screw module. At the same time, combined with the linear and rotational adjustment of the horizontal position adjustment component and the rotation adjustment component, it can ensure that the detected object is in the optimal detection position throughout the mass spectrometry analysis process, thereby improving the uniformity of the analysis.

[0018] 2. The mass spectrometer itself can obtain the shape, size, and surface features of the sample in real time through detection data from a height sensor and an object scanning camera. Simultaneously, the height sensor can accurately measure the relative height between the sample and the detection device. This data allows the mass spectrometer to precisely position and adjust the mass spectrometer detection head to the appropriate location, avoiding positioning errors caused by manual intervention. Furthermore, based on information obtained from the object scanning camera, the mass spectrometer detection head can automatically adjust the detection position and angle through lateral position adjustment and rotation adjustment components, ensuring accurate detection of each region and thus improving the accuracy of the analysis results.

[0025] First embodiment;

[0026] Reference Figure 1-3 As shown, a mass spectrometer with adjustable detection head height is provided in a preferred embodiment of the present invention, including a mass spectrometer detection stage 1: a lateral position adjustment component 2 is installed on the upper surface of the mass spectrometer detection stage 1, a rotation adjustment component 3 is assembled on the lateral position adjustment component 2, and a connecting seat 4 is installed on the rotation adjustment component 3.

[0027] The connecting seat 4 is mounted above the mass spectrometer detection stage 1 and an outer casing 5 is installed at its end. A linear screw module 6 is installed inside the outer casing 5. The linear screw module 6 is vertically arranged and a mass spectrometer detector body 51 is mounted on its side. The mass spectrometer detector body 51 is electrically connected to the mass spectrometer detection head 52. An opening is provided at the bottom of the outer casing 5 for the mass spectrometer detection head 52 to be adjusted vertically.

[0028] The lateral position adjustment component 2 includes a lateral adjustment platform 21 disposed on the upper surface of the mass spectrometer detection stage 1. Two linear tracks 22 are vertically arranged on the side of the lateral adjustment platform 21. The two linear tracks 22 are arranged in parallel and each of them has two track sliders 23 that are fitted and slidably mounted on them.

[0029] The rotation adjustment assembly 3 includes a motor base 31 disposed on the side of the four track sliders 23. The motor base 31 is connected to the four track sliders 23, and a rotary motor 32 is mounted on the side of the motor base 31.

[0030] A height sensor 7 is installed on the side of the outer casing 5, and an object scanning camera 8 is installed at the bottom of the outer casing 5. The height sensor 7 and the object scanning camera 8 are electrically connected to the mass spectrometer body 51 through wires.

[0031] In this embodiment, the interlocking motion between the lateral position adjustment component 2 and the rotation adjustment component 3 allows the connecting seat 4 mounted on the rotation adjustment component 3 to be laterally adjusted by the lateral position adjustment component 2, thereby driving the external casing 5 and the mass spectrometer body 51 to perform overall lateral position adjustment. Meanwhile, the rotation adjustment component 3 can rotate the connecting seat 4. This allows the mass spectrometer body 51 and the mass spectrometer detection head 52 to be further aligned with the object, facilitating mass spectrometry detection of the object. Compared to traditional single height adjustment, the mass spectrometer body 51 of this application can achieve linear height adjustment in the vertical position through the drive control of the linear screw module 6. Combined with the linear and rotational adjustments of the lateral position adjustment component 2 and the rotation adjustment component 3, it can ensure that the object being detected is in the optimal detection position throughout the mass spectrometry analysis process, thereby improving the uniformity of the analysis.

[0032] Furthermore, in practical use, the mass spectrometer body 51 can obtain the shape, size, and surface features of the sample in real time through the detection data from the height sensor 7 and the object scanning camera 8. Simultaneously, the height sensor 7 can accurately measure the relative height between the sample and the detection device. This data allows the mass spectrometer body 51 to accurately position and adjust the mass spectrometer detection head 52 to a suitable location, avoiding positioning errors caused by manual intervention. Furthermore, based on the information scanned by the object scanning camera 8, the mass spectrometer detection head 52 can automatically adjust the detection position and angle through the lateral position adjustment component 2 and the rotation adjustment component 3, ensuring accurate detection of each region and thus improving the accuracy of the analysis results.

[0033] It should be noted that the height sensor 7 and the object scanning camera 8 can monitor the position and height of the object being detected, enabling the mass spectrometer detection head 52 to determine the object's condition in real time and automatically adjust the detection height position of the mass spectrometer detection head 52 via the linear lead screw module 6. The height sensor 7 and the object scanning camera 8 can also be electrically connected to an external display screen to display the object's data for user viewing, thereby precisely adjusting the positions of the lateral position adjustment component 2 and the rotation adjustment component 3, achieving further position control of the external chassis 5 and the mass spectrometer body 51.

[0034] Second embodiment;

[0035] Reference Figure 2-3 As shown, the lateral position adjustment assembly 2 also includes two bearing seats 24 disposed on the side of the lateral adjustment platform 21, and a threaded screw 25 is rotatably disposed between the two bearing seats 24. Bearing components are disposed within the bearing seats 24 to ensure the smooth rotation of the threaded screw 25.

[0036] Third embodiment;

[0037] Reference Figure 2-3 As shown, a screw nut 26 is externally threaded onto the lead screw 25, and the side of the screw nut 26 is connected to the motor base 31. When the lead screw 25 rotates in both directions, it is limited by the transverse adjustment table 21, the linear track 22, and the track slider 23, allowing the motor base 31 to reciprocate linearly within the stroke range of the lead screw 25, following the screw nut 26.

[0038] Fourth embodiment;

[0039] Reference Figure 2-3 As shown, a reversible motor 27 is mounted on the side of the horizontal adjustment platform 21. The end of the threaded screw 25 passes through one of the bearing seats 24 and extends to connect with the output end of the reversible motor 27. The reversible motor 27 can be used to drive the threaded screw 25 to rotate in both directions.

[0040] Fifth embodiment;

[0041] Reference Figure 1-3 As shown, a transmission rod 33 is vertically connected to the output end of the rotary motor 32. A base plate 34 is mounted on the top of the transmission rod 33, and the base plate 34 is located below and connected to the connecting seat 4. When the user connects the rotary motor 32 to an external power source, the rotary motor 32 can drive the transmission rod 33 and the base plate 34 to rotate, thereby using the rotation of the base plate 34 to drive the connecting seat 4 to rotate.

[0042] It should be noted that, in use, the power connection method of the forward and reverse motor 27 and the linear screw module 6 is existing technology, which can be implemented by those skilled in the art through simple programming. It is common knowledge in the field. We only use it and do not modify it. Therefore, the control method and circuit connection will not be described in detail.

[0043] The mass spectrometer body 51, height sensor 7, and object scanning camera 8 are all connected to a data display screen. The data display screen displays data based on the image scanned by the object scanning camera 8 and the height feedback from the height sensor 7. The operator can observe the data display screen and drive the lateral position adjustment component 2 and the rotation adjustment component 3 to adjust the mass spectrometer body 51 and the mass spectrometer detection head 52 to the optimal detection position to ensure that each part of the object can be accurately aligned with the detection area of ​​the mass spectrometer detection head 52.

[0044] Specific implementation process:

[0045] Step 1: When a user needs to perform mass spectrometry analysis on an object, the object is first placed on the mass spectrometry detection stage 1. Then, the mass spectrometer itself 51 uses the object scanning camera 8 to perform a preliminary scan of the sample. The object scanning camera 8 can acquire the shape, size, and surface information of the object in real time. Through computer vision technology, the object scanning camera 8 can also identify the sample's boundaries, position, and geometric features. During the scanning process, the height sensor 7 provides precise height data to help determine the distance changes in various areas of the object's surface.

[0046] Step 2: Based on the image scanned by the object scanning camera 8 and the height feedback from the height sensor 7, the mass spectrometer body 51 can analyze the optimal detection position of the object being detected. Once the object is positioned, the operator can observe the data display screen, thereby driving the lateral position adjustment component 2 and the rotation adjustment component 3 to adjust the mass spectrometer body 51 and the mass spectrometer detection head 52 to the optimal detection position, so as to ensure that each part of the object can be accurately aligned with the detection area of ​​the mass spectrometer detection head 52.

[0047] Step 3: Once the mass spectrometer detection head 52 is aligned with the object to be detected, mass spectrometry detection of the object can be achieved. At the same time, during the detection of the object, the user can also drive the linear lead screw module 6 to further adjust the detection height of the mass spectrometer detection head 52, thereby further improving the detection range of the object.
