Description

Technical Field

[0001] This application relates to the field of ion source equipment technology, and in particular to an adjustable scanning control device for an ion source. Background Technology

[0002] The quadrupole mass analyzer is a commonly used mass analyzer in electrospray ionization scanning. Its function is to screen and separate ions based on their mass-to-charge ratio. It consists of four parallel and uniformly arranged metal rods. When the ion beam enters the quadrupole mass analyzer, a fixed DC voltage and a radio frequency (RF) voltage are applied to the rod electrodes. The potentials of the two pairs of electrodes are opposite. Under specific electric field strength and RF frequency, only ions with a specific mass-to-charge ratio can maintain stable axial movement and eventually reach the detector through the electric field. Ions with other mass-to-charge ratios will collide with the rods and be "filtered out" due to increased amplitude. By adjusting the DC and RF voltages, the screening of ions with different mass-to-charge ratios and the mass spectrometry scanning function 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.

[0003] When a mass analyzer is installed in a mass spectrometer, the detection level of the mass spectrometer is largely determined by the processing and assembly precision of the mass analyzer. In existing quadrupole mass analyzers, the bars are usually in a fixed state, which makes it impossible to adjust the distance between the bars, thus greatly limiting its adaptability to different detection requirements.

[0004] Chinese patent with announcement number "CN220367884U" discloses a position-adjustable quadrupole mass analyzer. The analyzer uses an adjustment mechanism that includes an adjustment component and a support component. The fixed sleeve in the adjustment component is fixedly connected to the surface of the protective sleeve. Four lead screws are rotatably connected at equal intervals on the upper inner wall of the fixed sleeve. The sliding sleeve can be moved by rotating the rotating ring, thereby achieving the purpose of adjusting the position of the rods and making the mass analyzer suitable for different occasions.

[0005] However, this quality analyzer still has certain defects and shortcomings in the adjustment process. First, during use, a gear ring and gears are used to drive multiple lead screws to rotate synchronously. However, the rotating rings on both sides are set independently during adjustment. To adjust the position of each rod synchronously, both rings must be adjusted synchronously, which is obviously cumbersome. Moreover, if the rotation speed of the two rings is not uniform, it will squeeze the rods, resulting in deviation, deformation, or even damage to the rods. At the same time, its adjustment must be done manually. If the quadrupole quality analyzer is located inside the equipment, it obviously needs to be disassembled for adjustment. The subsequent operation is cumbersome and inconvenient. In summary, this quality analyzer has many problems in practical applications and needs to be improved and optimized. Summary of the Invention

The inner side of the slide plate is connected to a linkage mechanism. An installation component is fixedly installed on the inner side of the slide plate. A rod is installed at the inner end of the slide plate through the installation component.

[0009] Optionally, the mounting component includes a connecting rod, which is fixedly mounted on the inner side of the slide plate. An mounting sleeve is fixedly mounted on the inner end of the connecting rod. A fixing screw is threaded to the outer end of the mounting sleeve located inside the side mounting bracket. The rod passes through the inner side of the mounting sleeve and is installed by being abutted against by the inner end of the fixing screw.

[0010] Optionally, the fixing screw is configured as a hand-tightening screw, and the outer surface of the outer end of the fixing screw is fixedly connected with anti-slip protrusions at equal intervals.

[0011] Optionally, the linkage mechanism includes a guide rail, which is fixedly installed on both sides and the front and rear ends of the adjustment mechanism. Both ends of the guide rail are slidably connected to movable blocks. The outer side of each movable block is rotatably connected to a connecting shaft, and the outer end of the connecting shaft is rotatably connected to the inner side of the slide plate.

[0012] Optionally, the cross-sectional shape of the slide plate and the movable block is set to a convex shape, the cross-sectional shape of the internal cavity of the guide rail and the internal cavity of the side slide groove is also set to a convex shape, and wear-resistant pads are fixedly connected to the outer sides of the slide plate and the movable block.

[0013] Optionally, mounting plates are fixedly installed on the top front and rear sides and the bottom front and rear sides of the side mounting frame, and the outer corners of the side mounting frame and the middle mounting frame are all set to be arc-shaped.

[0014] Optionally, the adjustment mechanism includes a side rail frame, which is fixedly installed on the top and bottom of the central frame. A lead screw is rotatably connected inside the side rail frame. The two ends of the lead screw have opposite thread directions. Displacement blocks are threaded to both ends of the lead screw. Connecting members are fixedly and rotatably connected to both sides of the displacement blocks. The outer ends of the connecting members are rotatably connected to the inner ends of the guide rails, respectively.

[0015] Optionally, the connector includes a fixing block, which is fixedly installed on both sides of the displacement block. A side plate is fixedly installed on the outer side of the fixing block, and a connecting rod is rotatably connected to the lower outer side of the side plate. The outer end of the connecting rod is rotatably connected to the inner side of the guide rail.

[0016] Optionally, the drive mechanism includes a side bracket and a synchronous pulley. The side bracket is fixedly installed on the front end of a side rail frame near the center frame.

[0018] In summary, this application includes the following beneficial technical effects:

[0019] 1. The movable mechanism of this device has significant advantages in actual use. When installing the rod, simply insert the rod into the inside of the mounting sleeve and tighten the fixing screw to secure the rod. After installation, the drive mechanism and the adjustment mechanism work together to drive the two guide rails to move inward. The inward movement of the guide rails causes the sliding plate to slide in the side groove. The side groove provides auxiliary guidance, and the sliding plate then drives the mounting rod to move inward, causing the mounting sleeve and rod to move inward into the annular groove. The adjustment components can be linked to adjust each sliding plate synchronously, achieving unified, rapid, and synchronous displacement of multiple rods. This avoids asynchronous squeezing and damage to the rods, improves the service life of the rods, and the fixing screw is hand-tightened, so disassembling and assembling the rods only requires manual turning, which improves the convenience of disassembly, assembly, and maintenance.

[0020] 2. The coordination between the adjustment mechanism and the drive mechanism makes this device perform excellently. When the drive motor is started, the motor on the side frame assists in driving the synchronous pulley to rotate. The synchronous pulleys are driven by a synchronous belt. One drive motor can drive two synchronous pulleys to rotate synchronously, which in turn drives the lead screw inside the side rail frame to rotate. The rotation of the lead screw drives the displacement block to move the fixed block. Because the threads at both ends of the lead screw turn in opposite directions, they can synchronously drive the displacement blocks on both sides to reciprocate. The synchronous movement of the displacement blocks drives the fixed block, side plate and connecting rod to move. The connecting rod pushes the guide rail to move in linkage. This allows the device to automatically and synchronously drive the displacement of the four rods during use, realize synchronous adjustment, improve the convenience of overall adjustment, eliminate the need for manual adjustment, and have an automatic adjustment function.

[0021] 3. This device excels in the installation, adjustment, disassembly, and maintenance of rods through the cooperation of the movable mechanism, adjustment mechanism, and drive mechanism. The movable mechanism ensures simple installation and rapid synchronous adjustment of rods, avoiding damage and extending service life. The adjustment mechanism, in conjunction with the drive mechanism, achieves automated synchronous adjustment, improving adjustment efficiency and convenience. The hand-tightening fixing screw facilitates disassembly and assembly without complex operations. These features give this device significant advantages in practical applications, bringing great convenience to users, improving work efficiency and device reliability, and making it suitable for various occasions requiring precise adjustment of rod positions.

[0031] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0032] This application discloses an adjustable scanning control device for an ion source. For example... Figure 1-8 As shown, an adjustable scanning control device for an ion source adopts the following technical solution: it includes a frame 1, with side mounting brackets 2 fixedly installed at both ends of the frame 1. An annular groove 3 is opened in the middle of the inner side of the side mounting bracket 2. Movable mechanisms 5 are movably installed at the four corners of the side mounting bracket 2. A linkage mechanism 6 is movably installed inside the movable mechanism 5. A central mounting bracket 4 is fixedly installed in the middle of the frame 1. An adjustment mechanism 7 is fixedly installed at the top and bottom of the central mounting bracket 4. The inner side of the linkage mechanism 6 is fixedly connected to both sides of the adjustment mechanism 7. Both sides of the adjustment mechanism 7 are connected to the inner side of the linkage mechanism 6. A drive mechanism 9 is provided at the front end of the central mounting bracket 4. The rear side of the drive mechanism 9 is fixedly connected to the front side of the adjustment mechanism 7. A rod 8 is installed on the inner side of the side mounting bracket 2 through the movable mechanism 5.

[0033] The moving mechanism 5 includes side sliding grooves 51, which are located at the four inner corners of the side mounting frame 2. Each side sliding groove 51 is inclined towards the center of the annular groove 3. The interior of each side sliding groove 51 is slidably connected to a sliding plate 52. The inner side of the sliding plate 52 is connected to the linkage mechanism 6. A mounting component 53 is fixedly installed on the inner side of the sliding plate 52. A rod 8 is mounted on the inner end of the sliding plate 52 via the mounting component 53. The side sliding grooves 51 located at the four inner corners of the side mounting frame 2 are all inclined towards the center of the annular groove 3. This design provides a specific direction and path for the sliding plate 52 to slide. The sliding plate 52 slides within the side sliding grooves 51, allowing the linkage mechanism 6 connected to it to transmit power and motion more stably during operation. The mounting component 53 on the inner side of the sliding plate 52 is a rod. The installation of rod 8 provides a reliable connection point, making the installation of rod 8 more stable. Through the movable mechanism 5, the position adjustment of rod 8 can be more flexible and precise. When the position of rod 8 needs to be adjusted, the sliding of the slide plate 52 in the side sliding groove 51 can drive the installation part 53 and rod 8 to move, thereby realizing the adjustment of the position of rod 8. This adjustment method can ensure the synchronous adjustment of multiple rods 8, avoiding the performance degradation of the device due to asynchronous adjustment. At the same time, the design of the movable mechanism 5 enables the device to better adapt to different working conditions and requirements during operation, improving the versatility and adaptability of the device. In addition, the structure of the movable mechanism 5 is relatively simple, easy to manufacture and maintain, reducing the production cost and maintenance difficulty of the device.

[0034] Please refer to Figures 1-7The mounting component 53 includes a connecting rod 531, which is fixedly installed on the inner side of the slide plate 52. An installation sleeve 532 is fixedly installed on the inner end of the connecting rod 531. A fixing screw 533 is threadedly connected to the outer end of the installation sleeve 532, located inside the side mounting bracket 2. A rod 8 passes through the inner side of the installation sleeve 532 and is tightened by the inner end of the fixing screw 533. The fixing screw 533 is a hand-tightening screw, and anti-slip protrusions are evenly spaced on the outer surface of the knob at the outer end of the fixing screw 533. The connecting rod 531, fixed to the inner side of the slide plate 52, provides stable support for the installation sleeve 532. The installation sleeve 532 is threadedly connected to the fixing screw 533, making the installation and fixing of the rod 8 more reliable. The rod 8 is installed by being inserted into the inner side of the mounting sleeve 532 and pressed against the inner end of the fixing screw 533. This installation method is simple to operate. The fixing screw 533 is a hand-tightening screw, which greatly facilitates the installation and disassembly operation during use. The adjustment and replacement of the rod 8 can be completed quickly without the aid of other tools. The outer surface of the knob at the outer end of the fixing screw 533 is fixedly connected with anti-slip protrusions at equal intervals, which increases the friction during hand-tightening operation, prevents slippage, and improves the accuracy and stability of operation. This design of the mounting part 53 makes the installation and adjustment of the rod 8 more flexible and efficient, adapting to different usage needs and working scenarios. At the same time, its simple structure makes it easy to manufacture and maintain, reducing the cost and maintenance difficulty of the device.

[0035] Please refer to Figures 1-6The linkage mechanism 6 includes a guide rail 61, which is fixedly installed on both sides and the front and rear ends of the adjustment mechanism 7. Movable blocks 62 are slidably connected to both ends of the guide rail 61. A connecting shaft 63 is rotatably connected to the outer side of the movable blocks 62. The outer end of the connecting shaft 63 is rotatably connected to the inner side of the slide plate 52. The cross-sectional shape of both the slide plate 52 and the movable blocks 62 is convex. The cross-sectional shape of the internal cavity of the guide rail 61 and the internal cavity of the side slide groove 51 is also convex. Wear-resistant pads are fixedly connected to the outer sides of both the slide plate 52 and the movable blocks 62. Mounting plates 10 are fixedly installed on the top and front and rear sides and the bottom and front and rear sides of the side mounting bracket 2. The outer corners of the side mounting bracket 2 and the middle mounting bracket 4 are rounded. The guide rail 61, fixed to both sides and the front and rear ends of the adjustment mechanism 7, provides a stable movement track for the movable blocks 62. The movable blocks 62 slide within the guide rail 61, achieving connection and transmission with the slide plate 52. The connecting shaft 63 on the outer side of the movable blocks 62 is rotatably connected to the inner side of the slide plate 52. This design makes the connection more flexible and adaptable to different movement needs. The cross-sectional shapes of the slide plate 52 and the movable block 62, as well as the cross-sectional shapes of the internal cavities of the guide rail 61 and the side slide groove 51, are all set to a convex shape. This design makes them more stable during movement, less prone to detachment, and ensures the accuracy and reliability of the movement. The wear-resistant pads fixedly connected to the outside of the slide plate 52 and the movable block 62 reduce wear during sliding and extend the service life of the components. The mounting plates 10 fixedly installed on the front and rear sides of the top and bottom of the side mounting frame 2 provide additional installation and fixing points for the entire device, enhancing the stability of the device. The external corners of the side mounting frame 2 and the middle mounting frame 4 are set to rounded arcs, reducing the risk of personnel being injured by sharp corners during operation, and also making the appearance of the entire device more streamlined and beautiful. This linkage mechanism 6 design makes the cooperation between various components of the device more tight during operation, improving the overall performance and working efficiency of the device.

[0036] Please refer to Figures 1-5 and Figure 8The adjusting mechanism 7 includes a side rail frame 71, which is fixedly installed on the top and bottom of the central mounting frame 4. A lead screw 72 is rotatably connected inside the side rail frame 71, with opposite thread directions at both ends. Displacement blocks 73 are threaded to both ends of the lead screw 72. Connecting members 74 are rotatably connected to both sides of the displacement blocks 73. The outer ends of the connecting members 74 are rotatably connected to the inner ends of the guide rail 61. Each connecting member 74 includes a fixing block 741, which is fixedly installed on the displacement blocks 73. On both sides of the 3, a side plate 742 is fixedly installed on the outer side of the fixing block 741. A connecting rod 743 is rotatably connected to the lower outer end of the side plate 742. The outer end of the connecting rod 743 is rotatably connected to the inner side of the guide rail 61. The side rail frame 71 is fixed to the top and bottom of the middle mounting frame 4, providing a stable installation position for the lead screw 72. The lead screw 72 is rotatably connected inside the side rail frame 71, and the threads at both ends are turned in opposite directions. This design allows the displacement blocks 73 at both ends to be driven synchronously when the lead screw 72 rotates. Moving in opposite directions, the connecting parts 74 on both sides of the displacement block 73 are rotatably connected to the inner ends of the guide rail 61, ensuring effective power transmission. The fixing block 741 in the connecting part 74 provides a solid mounting base for the side plate 742. The connecting rod 743 rotatably connected to the lower outer end of the side plate 742 further enhances the flexibility of the connection. When the lead screw 72 rotates, the displacement block 73 drives the fixing block 741 to move. The fixing block 741 pushes the guide rail 61 to move through the side plate 742 and the connecting rod 743. This adjustment mechanism 7 can accurately control the position of the guide rail 61, thereby achieving accurate adjustment of the position of the rod 8. Its structural design is reasonable, and the cooperation between the various components is tight, which can efficiently complete the adjustment task. At the same time, this adjustment method is stable and reliable, and can adapt to different working conditions and requirements, improving the versatility and adaptability of the device. In addition, the operation of the adjustment mechanism 7 is relatively simple, easy to control and maintain, reducing the use cost and maintenance difficulty of the device.

[0037] Please refer to Figures 1-5The drive mechanism 9 includes a side bracket 91 and a synchronous pulley 92. The side bracket 91 is fixedly installed on the front end of a side rail frame 71 near the center mounting frame 4. The synchronous pulley 92 is rotatably connected to the front end of the side rail frame 71. The back of the synchronous pulley 92 is fixedly connected to the front end of the lead screw 72. A drive motor 93 is fixedly connected to the front of the side bracket 91. The output end of the drive motor 93 is connected to the synchronous pulley 92 located at the upper end. The synchronous pulleys 92 are connected to each other by a synchronous belt 94. Mounting holes 11 are provided on the outer side of the mounting plate 10. The mounting holes 11 are countersunk holes. The side shape of the displacement block 73 and the internal cross-sectional shape of the rail frame are both T-shaped. The side bracket 91 is fixed on the front end of a side rail frame 71 near the center mounting frame 4 and serves as the drive motor 93 and the synchronous pulley. 92 provides a stable installation position. The synchronous pulley 92 is rotatably connected to the front end of the side rail frame 71 and its back is fixedly connected to the front end of the lead screw 72, ensuring that power can be effectively transmitted to the lead screw 72. The output end of the drive motor 93 on the front of the side frame 91 is connected to the synchronous pulley 92 located at the upper end. The synchronous pulleys 92 are connected to each other by a synchronous belt 94. This design enables one drive motor 93 to drive multiple synchronous pulleys 92 to rotate synchronously, thereby making multiple lead screws 72 operate synchronously, ensuring the coordination and stability of the device operation. The mounting holes 11 on the outer side of the mounting plate 10 are countersunk holes, which facilitates the installation and fixing of the device, and at the same time makes the surface of the installed device smoother and more aesthetically pleasing. The side shape of the displacement block 73 and the internal cross-sectional shape of the rail frame are both T-shaped. The character-shaped setting 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 automated adjustment and control, improves work efficiency, reduces the difficulty and labor intensity of manual operation, and at the same time, its compact structure occupies little space and is suitable for various working environments.

[0038] The implementation principle of the adjustable scanning control device for an ion source in this application embodiment is as follows: By setting the 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 is twisted to make it press against the rod 8, thus completing the installation operation of the rod 8. After the rod 8 is installed, the drive mechanism 9 and the adjustment mechanism 7 can work together. 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 cause the slide plate 52 to slide inside the side sliding groove 51, and the side sliding groove 51 can assist in guiding the slide plate 52. As the guide rails 61 move inward, the slide plate 52 will cause the connecting rod 531 of the mounting part 53 to move inward. The inward movement of the connecting rod 531 of the mounting part 53 will cause the mounting sleeve 532 to move inward. The mounting sleeve 532 moves inward, causing the rod 8 to move towards the inside of the annular groove 3. Through the linkage of the adjustment component, the sliding plates 52 can be adjusted synchronously. This design allows the device to adjust the synchronous displacement of multiple rods 8 in a unified and rapid manner, avoiding the situation where the rods 8 are crushed and damaged due to asynchronous displacement. This method can improve the overall service life of the rods 8 and prevent damage to the rods 8. During use, the mounting sleeve 532 is installed using a fixing screw 533, and the fixing screw 533 is set as a hand-tight screw. Therefore, during the disassembly and assembly of the rods 8, the disassembly and assembly operation can be quickly adjusted by simply turning the fixing screw 533 by hand. This design enables the device to quickly disassemble and assemble the rods 8, greatly improving the convenience of disassembly, assembly, and maintenance during the overall use of the device.

[0039] By coordinating the adjustment mechanism 7 and the drive mechanism 9, this device exhibits excellent performance during use. Specifically, a series of functions can be achieved by starting the drive motor 93. The drive motor 93 on the side frame 91 assists in driving the synchronous pulleys 92 to rotate. The synchronous pulleys 92 are connected by a synchronous belt 94. In this way, one drive motor 93 can drive two synchronous pulleys 92 to rotate synchronously. The rotation of the synchronous pulleys 92 drives the lead screw 72 inside the side rail frame 71 to rotate. The rotation of the lead screw 72 assists in driving the displacement block 73 to move the fixed block 741. Since the threads at both ends of the lead screw 72 turn in opposite directions, they can rotate synchronously. The displacement blocks 73 on both sides reciprocate synchronously. By adjusting the synchronous movement of the displacement blocks 73, the fixed block 741, side plate 742, and connecting rod 743 can be moved synchronously. The displacement of the connecting rod 743 can drive the guide rail 61 to move in linkage. This design allows the device to automatically and synchronously move the four rods 8 synchronously during use. By adjusting the synchronous displacement of the four rods 8, the device can be adjusted synchronously, which improves the convenience of the overall adjustment of the device. Moreover, the device does not require manual adjustment and has an automatic adjustment function, which can improve the adjustment efficiency of the device during use and bring great convenience to the user.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
