Description

Technical Field

[0001] The present application relates to the technical field of electrospray ion source equipment, and in particular to an adjustable mounting device for an electrospray ion source. Background Art

[0002] Electrospray ion source is mainly used in mass spectrometry analysis. Its core function is to convert sample molecules into ions. It allows the sample dissolved in a volatile solvent to pass through a quartz capillary at a certain flow rate, and applies a high voltage to the tip of the capillary to form charged droplets of the solution. As the solvent evaporates, the droplets gradually become smaller and eventually produce ions. This method can ionize molecules under mild conditions and reduce molecular decomposition. It is also suitable for thermally unstable compounds. It can also produce multi-charged ions, allowing biological macromolecules such as proteins and peptides to enter the detection range of the mass spectrometer, expanding the application of mass spectrometry in macromolecular research, and has a good ionization effect on polar compounds. It is also suitable for use with liquid chromatography. During the combination process, liquid chromatography first separates the components, then ionizes them through it, and then enters the mass spectrometer for detection, which improves the sensitivity and accuracy of the analysis. It can also be used to study non-covalent interactions and can well retain molecular structure information. The Chinese patent with the announcement number "CN216902797U" discloses a mass spectrometer ion source, which includes a top plate, a first motor is fixedly connected to the bottom of the top plate, the top plate is rotatably connected to a rotating plate through the first motor, the bottom of the rotating plate is rotatably connected to a rotating shaft, a mounting plate is fixedly connected to the bottom of the rotating shaft, the rotating plate is rotatably connected to the mounting plate through the rotating shaft, and the bottom of the mounting plate is clamped with an ion source. The advantages of the utility model are: the worm is driven to rotate by the second motor, and then the meshing relationship between the worm and the worm wheel drives the worm and the rotating shaft to rotate, so as to control the inclination angle of the ion source, and the transmission coefficient between the worm wheel and the worm enables the rotation of the second motor to more finely adjust the rotation angle of the rotating shaft, thereby improving the accuracy of the angle adjustment of the ion source, cooperating with the second motor to realize the multi-directional injection requirements below the ion source, and improving the degree of freedom of the ion source; Although the above-mentioned device has certain adjustment functions during application, it still has obvious defects and shortcomings. Among them, the problem that the device cannot adjust the height is particularly prominent. In the experiment of deep analysis of the composition changes of multi-layer structure materials, only by fine-tuning the height of the ion source can the depth action position of the ion beam be changed, and then accurate information at different depth levels can be obtained. Otherwise, only relatively superficial or general results can be obtained. For samples with uneven surfaces, only by adjusting the height can the ion beam adapt to its ups and downs and act evenly on the sample surface, thereby avoiding deviations in detection data and preventing some areas from being overloaded with information due to excessively strong ion beams, or insufficient information due to excessively weak ion beams. In terms of equipment, when there is a deviation in the focusing of the ion beam, adjusting the height can enable the ion beam to accurately align with the subsequent analysis instrument. The height adjustment can optimize the energy distribution of the ion beam on the sample surface, achieve the expected ion implantation effect or material modification effect, meet the needs of precise control of ion energy, and ensure the accuracy and reliability of the entire experiment. However, the existing equipment is obviously unable to adjust the height, and during the overall rotation adjustment of the equipment, the entire gravity of the ion source acts on the motor, which will bring a large load to the motor if used for a long time. At the same time, the rotation adjustment directly applies the entire ion source equipment to the motor, so that the gravity of the entire ion source is concentrated on the motor. In this way, the energy consumption of the motor during use is large, which can easily cause damage to the motor. Therefore, it is necessary to improve it. Summary of the invention

[0014] In summary, this application includes the following beneficial technical effects: 1. In the present invention, the adjustment mechanism brings significant advantages to the device. When the device is used, the second motor is started, which can drive the screw rod to rotate inside the bottom rail. Because the threads at both ends of the screw rod rotate in opposite directions, the two sliders can be synchronously driven to slide back and forth in the bottom rail when rotating. The adjustment slider moves inward, which will cause the linkage rod on the bottom hinge to rotate and adjust, thereby pushing the installation mechanism downward to achieve the downward displacement of the ion source body; the second motor is driven in the reverse direction, and the slider drives the linkage rod to pull the installation mechanism upward. Such a flexible height adjustment function enables the device to adapt to different experimental detection requirements.

The angle adjustment mechanism of the present invention has obvious advantages. During use, if the tilt angle needs to be adjusted, the cylinder at the adjustment component can be started. One cylinder extends and the other cylinder contracts, which can automatically pull out the installation mechanism, drive the fixing seat and the rotating shaft to rotate inside the hinge frame, and realize the rotation and tilt adjustment of the ion source body. The two cylinders are used to jointly suspend the ion source body. Compared with the existing motor drive, the suspension force is stronger and the stability is higher. The track and the slider of the adjustment mechanism are embedded and slidable, which further improves the suspension stability and prolongs the service life of the equipment. In addition, the ion source body is assisted in installation by the installation screw. The installation screw can be twisted to insert into the limit hole for stable installation. The anti-slip adjustment knob can be twisted to separate it from the installation hole for disassembly and maintenance, which is more convenient. 3. By setting up an installation mechanism to cooperate with the rotating mechanism, the device has an excellent performance in use. The first motor of the driving assembly is started, and the first motor on the concave seat drives the gear to rotate. Because the gear is engaged with the gear ring, the gear ring is driven to rotate, and then the turntable is driven to rotate, which assists in driving the bottom ion source body and the angle adjustment mechanism and adjustment assembly to rotate. During use, an annular support rail is set at the bottom of the top seat to engage and slide with the support ring, and the support frame at the bottom of the support ring is fixedly connected to the fixed seat to further support and reinforce the fixed seat. After the fixed seat is reinforced, it can share the gravity of the turntable, so that no matter whether it is rotation adjustment or angle adjustment, gravity will not act on the motor, which not only reduces the energy consumption of the motor, but also increases the service life of the motor, so that the ion source equipment as a whole can better adjust the ion source.

The adjustment component 32 includes a bottom rail 321, which is fixedly installed at the bottom of the fixed seat 31. One end of the bottom rail 321 is fixedly connected to a second motor 322. A screw rod 323 is fixedly installed at the output end of the second motor 322 through the bottom rail 321. The two ends of the screw rod 323 have opposite thread rotation directions.

At the same time, the screw rod 323 shares the gravity of the ion source body 4 to avoid the full effect of gravity on the motor, thereby extending the service life of the motor and improving the adaptability and reliability of the device.

[0022] Please refer to Figure 4-Figure 7The angle adjustment mechanism 6 includes an articulated frame 61 and a hanging assembly 62. The inner side of the top of the articulated frame 61 is hinged to the bottom of the linkage rod 326. The inner side of the articulated frame 61 is rotatably connected with a rotating shaft 63. A connecting seat 64 is fixedly installed in the middle of the outer surface of the rotating shaft 63. The bottom of the connecting seat 64 is fixedly connected to the top of the mounting mechanism 5.

[0023] Please refer to Figure 2-Figure 6The mounting mechanism 5 includes a mounting circular plate 51 and a limiting hole 52. The middle of the top of the mounting circular plate 51 is fixedly connected to the bottom of the connecting seat 64. The top two sides of the mounting circular plate 51 are fixedly connected to the base frame 622.

[0024] The implementation principle of an adjustable mounting device for an electrospray ion source in an embodiment of the present application is as follows: in the present invention, by setting an adjustment mechanism 3, the second motor 322 can be used to operate during the use of the device, and the second motor 322 can drive the screw rod 323 to rotate on the inner side of the bottom rail 321. Since the screw rod 323 is located on the inner side of the bottom rail 321, the slider 324 can be driven to slide in the bottom rail 321 during its rotation. It is worth noting that the threads at both ends of the screw rod 323 have opposite rotation directions, which means that when the screw rod 323 is driven to rotate by the second motor 322, the two sliders 324 can be synchronously driven to perform reciprocating sliding displacement. When the two sliders 324 are adjusted to move inward, the linkage rod 326 on the hinge 325 at the bottom of the slider 324 will rotate and adjust accordingly. As the slider 324 moves inward , the linkage rod 326 will push the installation mechanism 5 to move downward, and the downward movement of the installation mechanism 5 can adjust the downward displacement of the ion source body 4. Conversely, when the second motor 322 is driven in the reverse direction, the second motor 322 can drive the slider 324 to drive the linkage rod 326 to pull the installation mechanism 5 upward. In this way, the height of the ion source body 4 can be flexibly adjusted during use. In addition, the screw rod 323 is used in conjunction with the sliding mode of the slider 324. The screw rod 323 can share the gravity of the ion source body 4, which greatly enhances the stability of the device and avoids all gravity acting on the second motor 322, thereby significantly improving the service life of the second motor 322. This enables the device to better adapt to the needs of different experimental tests and greatly improves the overall adaptability of the device during use. The angle adjustment mechanism 6 of the present invention also has significant advantages, so that during the use of the device, if it is necessary to adjust its tilt angle, it is only necessary to start the cylinder 623 at the adjustment component 32. Specifically, one cylinder 623 is started to extend, and then the other cylinder 623 is started to contract. At this time, the installation mechanism 5 can be automatically pulled out to drive the fixing seat 31 and the rotating shaft 63 to rotate on the inner side of the hinge frame 61. In this way, the ion source body 4 can be flexibly adjusted to rotate and tilt, so that the rotation and tilt angle of the device as a whole can be flexibly adjusted. During use, since the two cylinders 623 are used to cooperate and jointly hang the ion source body 4, it is different from the prior art that uses electric Compared with the machine driven, the overall hanging force is stronger and has stronger stability. In addition, the adjustment mechanism 3 adopts the method of mutual engagement and sliding of the track and the slider 324, which further enhances the overall hanging stability and makes the overall service life of the device longer. In addition, the ion source body 4 adopts the installation screw 54 to assist in installation. During the specific operation, the installation screw 54 is twisted to insert the end of the installation screw 54 into the inner side of the limit hole 52, so as to assist in the stable installation of the ion source body 4. If disassembly and maintenance are required, only the anti-slip adjustment knob handle needs to be twisted to cause the installation screw 54 to be separated from the installation hole 11 for disassembly and assembly, so that the overall disassembly and assembly of the device is more convenient. By setting the installation mechanism 5 to cooperate with the rotating mechanism 2, during the use of the device, the first motor 222 of the driving assembly 22 can be started to operate, and the first motor 222 on the concave seat 221 can drive the gear 223 to rotate. Since the gear 223 and the gear ring 23 are meshed and connected, the gear ring 23 can be synchronously driven to rotate with the rotation of the gear 223, and the rotation of the gear ring 23 will drive the turntable 21 to rotate. At this time, the rotation of the turntable 21 can assist in driving the rotation of the ion source body 4 at the bottom, the angle adjustment mechanism 6 and the adjustment assembly. The angle adjustment mechanism 6 is used to adjust the angle and cooperate with the rotating mechanism 2 to rotate, so that the ion source body 4 at the bottom and the angle adjustment mechanism 6 can be ... as to drive the ion source body 4 at the bottom and the angle adjustment mechanism 6 to rotate, so as to drive the ion source body 4 at the bottom and the angle adjustment mechanism 6 to rotate, so as to drive the ion source body 4 at the bottom and the angle adjustment mechanism 6 to rotate, so as to drive the ion source body 4 at the bottom and the angle adjustment mechanism 6 to rotate, so as to drive the ion source body 4 at the bottom and the angle adjustment mechanism 6 to rotate, so as to drive The ion source equipment as a whole can better adjust the ion source. During use, since an annular supporting rail 33 is set at the bottom of the top seat 1, it is engaged and slid with the supporting ring 34, and the supporting frame 35 at the bottom of the supporting ring 34 is fixedly connected to the fixed seat 31. This design enables the whole to further support and reinforce the fixed seat 31. After the fixed seat 31 is supported and reinforced, it can share the gravity exerted on the turntable 21. In this way, no matter it is rotation adjustment or angle adjustment, the overall gravity of the device will not act on the motor. On the one hand, it reduces the energy consumption of the motor, and on the other hand, it can also increase the overall service life of the motor.

[0025] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
