Description

Technical Field

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

[0002] The quadrupole mass analyzer is a mass analyzer commonly used in electrospray ion source scanning. Its function is to screen and separate ions according to their mass-to-charge ratio. It consists of four parallel and evenly arranged metal rods. When the ion beam enters the quadrupole mass analyzer, a DC fixed voltage and a radio frequency voltage (RF) act on the rod-shaped electrodes. The potentials between the two pairs of electrodes are opposite. Under a specific electric field strength and radio frequency frequency, only ions with a specific mass-to-charge ratio can maintain stable motion in the axial direction and eventually reach the detector through the electric field, while ions with other mass-to-charge ratios will eventually hit the poles and be "filtered" out due to the increase in amplitude. By adjusting the DC and radio frequency voltages, the screening and mass spectrometry scanning functions of ions with different mass-to-charge ratios can be realized. This mass analyzer has a relatively simple structure, small size, and fast scanning speed, and is widely used in organic mass spectrometry analysis. When the mass analyzer is installed in a mass spectrometer for use, the detection level of the mass spectrometer is largely determined by the processing and assembly accuracy of the mass analyzer. The rods in the existing quadrupole mass analyzer are usually in a fixed state, which makes it impossible to adjust the distance between the rods. As a result, its adaptability is greatly limited when facing different detection requirements. The Chinese patent with the announcement number "CN220367884U" discloses a position-adjustable quadrupole mass analyzer, which includes an adjustment assembly and a support assembly through an adjustment mechanism. The fixed sleeve in the adjustment assembly is fixedly connected to the surface of the protective sleeve. The upper inner wall of the fixed sleeve is rotatably connected with four screw rods at equal distances. The sliding sleeve can be moved by rotating the rotating ring, thereby achieving the purpose of adjusting the position of the rod, so that the mass analyzer can be applied to different occasions; However, this mass analyzer still has certain defects and shortcomings in the adjustment process. First, during use, a gear ring is used to cooperate with a gear to drive multiple screws to rotate synchronously. However, the rotating rings on both sides are independently set during the adjustment process. To synchronously adjust the positions of each rod, it is necessary to synchronously adjust and rotate the two rings. Obviously, this operation is more cumbersome. Moreover, if the rotation speeds of the two rings are not uniform, the rods will be squeezed, resulting in deviations, deformations, or even damage to the rods. At the same time, it must be adjusted manually. If the quadrupole mass analyzer is located inside the equipment, it is obviously necessary to disassemble it for adjustment. The subsequent overall use operation is more cumbersome and inconvenient. In summary, this mass analyzer has many problems in practical applications and needs to be improved and optimized.

[0019] The movable mechanism 5 includes a side slide groove 51, which is opened at the four inner corners of the side mounting frame 2.

The design of this mounting component 53 makes the installation and adjustment of the rod 8 more flexible and efficient, and adapts to different usage requirements and work scenarios. At the same time, its structure is simple, easy to manufacture and maintain, and reduces the cost and maintenance difficulty of the device.

The outer end of the connecting shaft 63 is rotatably connected to the inner side of the slide plate 52. The cross-sectional shapes of the slide plate 52 and the movable block 62 are both set to a convex shape. The cross-sectional shapes of the internal cavity of the guide rail 61 and the internal cavity of the side slide groove 51 are also set to a convex shape. The outer sides of the slide plate 52 and the movable block 62 are fixedly connected with wear-resistant gaskets. The top front and rear sides of the side mounting frame 2 and the bottom front and rear sides are fixedly installed with mounting plates 10. The external corners of the side mounting frame 2 and the middle mounting frame 4 are set to be arc-shaped. The guide rail 61 is fixed on the front and rear ends of both sides of the adjustment mechanism 7, providing a stable motion track for the movable block 62.

The cross-sectional shapes of the slide plate 52 and the movable block 62 and the internal cavity of the guide rail 61 and the side slide groove 51 are all set to a convex shape. This design makes them more stable and not easy to fall out during movement, thereby ensuring the accuracy and reliability of movement.

[0023] Please refer to Figure 1-Figure 5The driving mechanism 9 includes a side frame 91 and a synchronous wheel 92. The side frame 91 is fixedly mounted on the front end of a side rail frame 71 close to the middle mounting frame 4. The synchronous wheel 92 is rotatably connected to the front end of the side rail frame 71. The back of the synchronous wheel 92 is fixedly connected to the front end of the screw rod 72. The front of the side frame 91 is fixedly connected with a driving motor 93. The output end of the driving motor 93 is transmission-connected to the synchronous wheel 92 at the upper end. The synchronous wheels 92 are transmission-connected through a synchronous belt 94. The outer side of the mounting plate 10 is provided with mounting holes 11, and the mounting holes 11 are set as countersunk holes. The side shape of the displacement block 73 and the internal cross-sectional shape of the rail frame are both T-shaped.

This design can realize that one drive motor 93 drives multiple synchronous wheels 92 to rotate synchronously, so that multiple screw rods 72 operate synchronously, ensuring the coordination and stability of the device operation, the mounting hole 11 opened on the outer side of the mounting plate 10 is set as a countersunk hole, which is convenient for the installation and fixation of the device, and at the same time makes the surface of the device after installation more flat and beautiful, and the side shape of the displacement block 73 and the internal cross-sectional shape of the rail frame are both T-shaped The design of the letter "Z" makes the movement of the displacement block 73 inside the rail frame more stable, less prone to deviation and shaking, and improves the accuracy and reliability of the adjustment mechanism 7. The overall design of the drive mechanism 9 enables the device to achieve automatic adjustment and control, improves work efficiency, and reduces the difficulty and labor intensity of manual operation. At the same time, its structure is compact, occupies little space, and is suitable for various working environments.

[0024] The implementation principle of an ion source adjustable scanning control device in the embodiment of the present application is as follows: by setting a movable mechanism 5, the device has significant advantages during actual use. Specifically, the rod 8 can be inserted into the inner side of the mounting sleeve 532, and then the fixing screw 533 can be twisted to make it press against the rod 8, so that the installation operation of the rod 8 can be completed. When the rod 8 is installed, the driving mechanism 9 and the adjusting mechanism 7 can cooperate and link. At this time, a series of actions can be achieved by driving the two guide rails 61 to move inward. The inward movement of the two guide rails 61 will drive the slide plate 52 to slide on the inner side of the side slide groove 51, and the side slide groove 51 can assist in guiding the slide plate 52. As the guide rails 61 move inward, the slide plate 52 will drive the connecting rod 531 of the mounting member 53 to move inward, and the inward movement of the connecting rod 531 of the mounting member 53 will prompt the mounting sleeve 532 to move inward. The mounting sleeve 532 moves inwardly, thereby driving the rod 8 to move inwardly toward the inner side of the annular groove 3. The adjusting components are linked to each other, and the sliding plates 52 can be adjusted to move in a synchronous manner. This design enables the device to uniformly and quickly adjust the synchronous displacement of multiple rods 8, avoiding the situation where the rod 8 is squeezed and damaged due to asynchronous adjustment displacement. This method can increase the service life of the rod 8 as a whole and prevent the rod 8 from being damaged. During use, the mounting sleeve 532 is installed using a fixing screw 533, and the fixing screw 533 is set as a hand-tightening screw. Therefore, during the disassembly and assembly of the rod 8, the disassembly and assembly operation can be quickly adjusted by twisting the fixing screw 533 by hand. This design can prompt the device to quickly disassemble and assemble the rod 8, greatly improving the convenience of disassembly and assembly during the overall use of the device. By arranging the adjustment mechanism 7 and the driving mechanism 9 to cooperate, the device can show excellent performance during use. Specifically, a series of functions can be realized by starting the driving motor 93. The driving motor 93 on the side frame 91 can assist in driving the synchronous wheel 92 to rotate, and the synchronous wheels 92 are connected by a synchronous belt 94. In this way, the two synchronous wheels 92 can be driven to rotate synchronously by one driving motor 93. The rotation of the synchronous wheel 92 will drive the screw rod 72 inside the side rail frame 71 to rotate. The rotation of the screw rod 72 can assist in driving the displacement block 73 to drive the fixed block 741 to move. Since the threads at both ends of the screw rod 72 rotate in opposite directions, they can be synchronously driven. The displacement blocks 73 on both sides are driven to reciprocate synchronously. By adjusting the synchronous movement of the displacement blocks 73, the fixed block 741, the side connecting plate 742 and the connecting rod 743 can be synchronously moved with the belt 94. The displacement of the connecting rod 743 can push the guide rail 61 to be linked. This design allows the device to automatically and synchronously move the four rods 8 with the belt 94 during use. By adjusting the synchronous displacement of the four rods 8, the device can be synchronously adjusted to move, thereby improving the convenience of the overall adjustment of the device. In addition, the device does not require manual adjustment and has the function of automatic adjustment, which can improve the adjustment efficiency of the device during the overall use of the device and bring great convenience to the use of the device.

[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.
