Description

Technical Field

[0001] This application relates to the technical field of instrument touchscreens, and in particular to an anti-misoperation controller touchscreen for ion source instrument state switching. Background Art

[0002] In the fields of modern scientific research and detection, the ion source instrument mass spectrometer plays a key role in multiple disciplines such as chemistry, biology, and environment with its powerful analytical capabilities. It can accurately determine the chemical composition and structure of substances, providing crucial data support for scientific researchers and detection personnel. Among them, the ion source instrument mass spectrometer state switching touchscreen, as the core component of human-computer interaction, integrates advanced touch technology and display functions, providing operators with a convenient and efficient way to control and monitor the instrument state. Through highly sensitive touch operations, users can easily achieve complex operations such as ionization mode conversion, ion energy adjustment, and scan range setting, while real-time obtaining key parameters, operating status information, and operation menus of the instrument, greatly improving the analysis efficiency and data accuracy.

[0003] The movable blood detection mass spectrometer disclosed in Chinese Patent Publication No. "CN118501239B" brings certain convenience to blood detection work. By setting components such as a base, a box body, a data display screen, and a printer, this mass spectrometer realizes the movable detection function. Its unique inclined detection and first electric telescopic rod control design can ensure that the instrument bottom plate is parallel to the ground during movement, effectively reducing the influence of instrument inclination on the detection results and improving the accuracy and reliability of detection.

[0004] However, in practical applications, this device still exposes some problems that need to be solved urgently. First of all, the outer surface of its touchscreen lacks an effective protective shielding structure. During the process of taking and placing experimental detection samples, it is very likely that the operator accidentally touches the touchscreen, resulting in misoperation, affecting the normal operation of the instrument and the accuracy of data. Secondly, after the sample enters the mass spectrometer, since the sample needs to be transported to the ion source through the injection system and complete preparation work such as gasification or ionization, and at the same time the ion source needs to reach a stable working state, the mass analyzer scans the mass-to-charge ratio range, and the detector performs signal processing and data acquisition also takes time. During this waiting period, the unshielded touchscreen is extremely likely to be accidentally pressed by the experimenter during other operations, such as sample preparation and utensil handling. These problems not only reduce the stability and reliability of instrument operation, but also may cause deviations in detection results, seriously affecting the actual application effect of the movable blood detection mass spectrometer. In summary, although the existing movable blood detection mass spectrometer meets the detection requirements to a certain extent, the misoperation problem caused by insufficient touchscreen protection limits its further promotion and application. Therefore, it is necessary to improve the existing technology design. Summary of the Invention

Detailed implementation mode

[0019] The following will further elaborate on this application in conjunction with the attached Figures 1-9 drawings.

[0020] The embodiment of this application discloses an anti-misoperation controller 34 touch screen for switching the state of an ion source instrument. As Figures 1-9 shown, it includes a base 1, an ion source mass spectrometer 2 is fixedly installed on the top of the base 1, a fixed arm 4 is fixedly installed on the upper end of the front side of the ion source mass spectrometer 2, and a touch screen device 3 is fixedly installed on the front side of the fixed arm 4; The touch screen device 3 includes a mounting housing 31, the mounting housing 31 is fixedly connected to the front end of a fixed arm 4, a displacement adjustment mechanism 32 is fixedly connected to the top of the mounting housing 31, a protective baffle 33 is fixedly installed at the lower end of the displacement adjustment mechanism 32, a controller 34 is fixedly connected inside the mounting housing 31, a touch operation screen 35 is fixedly connected to the front of the controller 34, the touch operation screen 35 is set as a capacitive touch screen, a linkage mechanism 36 is fixedly installed on the back of the protective baffle 33, a cleaning mechanism 37 is installed on the side of the linkage mechanism 36 close to the touch operation screen 35, and the rear side of the cleaning mechanism 37 is in fitting connection with the front of the touch operation screen 35.During use, the recognition camera 39 continuously monitors the situation in the front area of the installation housing 31. When no one is detected, the first motor 322 in the transfer mechanism 32 is started, driving the first lead screw 323 to rotate. The lead screw drives the slider 324 to slide within the guide rail 321, thereby causing the protective baffle 33 to descend smoothly and completely cover the capacitive touch operation screen 35, effectively preventing accidental touches that may lead to misoperations. When the recognition camera 39 detects someone approaching and preparing to operate, it quickly feeds back a signal to the controller 34 within the installation housing 31. The controller 34 controls the first motor 322 to reverse, the first lead screw 323 rotates in the reverse direction, the slider 324 slides reversely, and the protective baffle 33 moves upward and laterally, completely exposing the touch operation screen 35, facilitating the operator to perform the operation of switching the state of the ion source instrument. During the operation, if the display accuracy of the touch operation screen 35 is affected by contamination such as dust and human body fluids and needs to be cleaned, the second motor 3252 in the transfer mechanism 32 is started. The second motor 3252 drives the driving gear 3253 to rotate. The driving gear 3253 drives the driven gear 3254, and the driven gear 3254 drives the second lead screw 3256 to rotate. The second lead screw 3256 pushes the displacement block 3255 to slide, prompting the protective baffle 33 to move towards the side of the touch operation screen 35, making the silicone scraper 377 in the cleaning mechanism 37 closely adhere to the front of the touch operation screen 35. At the same time, during the movement of the protective baffle 33 driven by the first motor 322 driving the first lead screw 323, the linkage mechanism 36 on the back of the protective baffle 33 starts to work. The transmission gear 362 in the linkage mechanism 36 interacts with the rack 361. The transmission gear 362 moves laterally and rotates on its own under the drive of the rack 361, successively driving the first bevel gear 3631 and the second bevel gear 3636 to rotate. The second bevel gear 3636 drives the third lead screw 3633 to rotate. The third lead screw 3633 pushes the slip ring 3634 to move laterally. The correction block 3638 connected to the top of the slip ring 3634 slides on the guide rod 3637 to assist in correcting the movement trajectory of the slip ring 3634, ensuring its stable displacement. The slip ring 3634 drives the silicone scraper 377 and the auxiliary scraper 379 in the cleaning mechanism 37 to closely adhere to the touch operation screen 35 for horizontal and vertical inclined scraping and cleaning. The compression spring 375 pushes the substrate 376 in the cleaning mechanism 37, making the silicone scraper 377 and the auxiliary scraper 379 always stably adhere to the touch operation screen 35, further improving the cleaning effect. If the silicone scraper 377 accumulates stains and needs to be replaced, open the protective baffle 33, turn the hand-twist screw 374 to disengage it from the installation rail 371, and then the carriage 372 can be easily pulled out from the installation rail 371 to quickly complete the replacement of the silicone scraper 377 and the auxiliary scraper 379, ensuring that the touch screen always maintains a clear display and improving the fluency and reliability of the instrument operation.,

[0021] Please refer to Figures 4-7The cleaning mechanism 37 includes a mounting rail 371, which is fixedly mounted on the side of the slip ring 3634 away from the correction block 3638. The mounting rail 371 is slidably connected to a slide 372 inside, and a mounting arm 373 is fixedly connected to the bottom side of the slide 372. A hand-tightening screw 374 is threadedly connected to the mounting arm 373. The mounting arm 373 is connected to the mounting rail 371 through the hand-tightening screw 374. The two ends of the slide 372 are fixedly connected to a compression spring 375. The end of the compression spring 375 is fixedly connected to a base plate 376. The base plate 376 is installed with a screw on a side close to the touch operation screen 35. The silicone scraper 377 and the base plate 376 are fixedly connected to the two ends of the side close to the protective baffle 33 with a support shaft 378, the end of the support shaft 378 passes through the slide 372, and the support shaft 378 and the slide 372 are slidably connected. The two sides of the silicone scraper 377 are fixedly connected with auxiliary scrapers 379, and the auxiliary scrapers 379 are also made of anti-static silicone material. When the cleaning mechanism 37 of the device is working, when the protective baffle 33 drives the slip ring 3634 to move horizontally under the action of the adjustment mechanism 32 and the linkage mechanism 36, the slip ring 3634 drives the mounting rail 371 to move synchronously, and the slide 372 in the mounting rail 371 moves during the displacement process through the installation The hand-tightened screw 374 on the arm 373 is connected to the mounting rail 371 to maintain relative stability. When the touch screen 35 needs to be cleaned, the protective baffle 33 moves closer to the touch screen 35, so that the silicone scraper 377 and the auxiliary scraper 379 are closely attached to the surface of the touch screen 35. During the cleaning process, the compression spring 375 plays a role and continuously pushes the substrate 376, so that the silicone scraper 377 and the auxiliary scraper 379 are stably attached to the touch screen 35 to ensure the cleaning effect. The support shaft 378 passes through the slide 372 and can slide. When the compression spring 375 pushes the substrate 376, it plays an auxiliary supporting and guiding role to ensure that the substrate 376 is clean. The silicone scraper 377 and the auxiliary scraper 379 made of anti-static silicone material can clean the touch screen 35 in a horizontal and vertical manner under the drive of the protective baffle 33 to remove stains such as dust and body fluids. When the silicone scraper 377 has accumulated a lot of stains and needs to be replaced, it is only necessary to open the protective baffle 33 and twist the hand-tightening screw 374 to disengage it from the mounting rail 371. The slide 372 can be easily pulled out of the mounting rail 371, and the silicone scraper 377 and the auxiliary scraper 379 can be quickly replaced, which facilitates the maintenance of the cleaning mechanism 37 and ensures that it can continuously and efficiently clean the touch screen 35.

[0022] Please refer to Figures 3-6, the adjustment mechanism 32 includes a guide rail 321, the guide rail 321 is fixedly installed on the top of the installation housing 31, one end of the guide rail 321 is fixedly connected with a first motor 322, the output end of the first motor 322 penetrates through the guide rail 321 and is fixedly connected with a first lead screw 323, a slider 324 is threadedly connected to the outer surface of the first lead screw 323, the bottom of the slider 324 is fixedly connected with a fine adjustment component 325, the fine adjustment component 325 includes a side rail 3251, the side rail 3251 is fixedly connected to the bottom of the slider 324, the rear end of the bottom of the side rail 3251 is fixedly connected with a second motor 3252, the output end of the second motor 3252 is fixedly connected with a driving gear 3253, the rear end of the side rail 3251 is rotatably connected with a driven gear 3254, the driving gear 3253 and the driven gear 3254 are meshed and connected, a displacement block 3255 is slidably connected inside the side rail 3251, a second lead screw 3256 is rotatably connected inside the side rail 3251, the second lead screw 3256 is connected to the front of the driven gear 3254, the protective baffle 33 is fixedly connected to the bottom of the displacement block 3255. During use, when it is necessary to protect or operate the touch operation screen 35, according to the signal fed back by the recognition camera 39, if it is detected that no one is approaching, the first motor 322 is started, and its output end drives the first lead screw 323 to rotate inside the guide rail 321. Since the first lead screw 323 is threadedly connected to the slider 324, the slider 324 moves linearly along the guide rail 321, and the fine adjustment component 325 connected to the bottom of the slider 324 moves accordingly, thereby driving the protective baffle 33 to rise or fall, realizing the shielding or exposure of the touch operation screen 35. When it is necessary to clean the touch screen, the second motor 3252 is started, and its output end drives the driving gear 3253 to rotate. The driving gear 3253 meshes with the driven gear 3254, thereby driving the driven gear 3254 to rotate. The driven gear 3254 drives the second lead screw 3256 to rotate inside the side rail 3251. Since the second lead screw 3256 is threadedly connected to the displacement block 3255, the displacement block 3255 slides inside the side rail 3251, and the protective baffle 33 fixedly connected to the bottom of the displacement block 3255 also approaches or moves away from the touch operation screen 35 accordingly. When the protective baffle 33 approaches the touch screen, it prompts the silicone scraper 377 in the cleaning mechanism 37 to fit the touch screen, so as to perform a cleaning operation on the touch screen in the subsequent linkage. Through the coordinated cooperation of the first motor 322 and the second motor 3252, the precise adjustment of the position and angle of the protective baffle 33 is realized, meeting the protection and cleaning requirements of the touch operation screen 35 in different working scenarios.

[0023] Please refer to Figures 1-2, an installation sleeve 38 is installed in the middle of the upper end of the front surface of the installation housing 31, and an identification camera 39 is fixedly installed inside the installation sleeve 38. During use, the identification camera 39 installed in the installation sleeve 38 in the middle of the upper end of the front surface of the installation housing 31 continuously monitors the front area of the installation housing 31 in real time. It identifies whether someone is approaching by capturing features such as the thermal radiation and movement changes of the human body. When it detects that there is no one in front of the installation housing 31, the identification camera 39 transmits this signal to the connected controller 34. The controller 34 then controls the first motor 322 in the transfer mechanism 32 to start, driving the protective baffle 33 to descend to block the capacitive touch operation screen 35 and prevent misoperation. When it detects that someone is approaching and about to operate the instrument, the identification camera 39 quickly feeds back the signal to the controller 34. The controller 34 controls the first motor 322 to reverse, causing the protective baffle 33 to rise and expose the touch operation screen 35, facilitating operations such as the state switching of the ion source instrument by the operator. After the operator finishes the operation and leaves, the identification camera 39 detects no one again and then transmits the signal to the controller 34 again, triggering the protective baffle 33 to descend again and re-cover the touch operation screen 35, realizing a fully automated intelligent protection monitoring function and ensuring the stability and accuracy of instrument operation.

[0024] Please refer to Figures 4-8, the linkage mechanism 36 includes a rack 361 and a transmission gear 362. The rack 361 is fixedly connected to the inner bottom of the installation housing 31. The transmission gear 362 is rotatably connected to the lower end of the back side of the protective baffle 33 near the slider 324. The transmission gear 362 and the rack 361 are meshed and connected. A linkage component 363 is fixedly connected to the side of the transmission gear 362 close to the touch operation screen 35. The linkage component 363 is connected to the cleaning mechanism 37. The linkage component 363 includes a first bevel gear 3631 and a mounting bracket 3632. The mounting bracket 3632 is fixedly installed on the back side of the protective baffle 33 near the transmission gear 362. A third lead screw 3633 is rotatably connected to one end of the mounting bracket 3632 far from the transmission gear 362 and close to the cleaning mechanism 37. A sliding ring 3634 is threadedly connected to the outer surface of the third lead screw 3633. The bottom of the sliding ring 3634 is connected to the cleaning mechanism 37. A second bevel gear 3636 is fixedly connected to one end of the third lead screw 3633 close to the first bevel gear 3631. The second bevel gear 3636 and the first bevel gear 3631 are meshed and connected. A guide rod 3637 is rotatably connected to the side of the mounting bracket 3632 far from the transmission gear 362. A correction block 3638 is slidably connected to the outer surface of the guide rod 3637. One side of the correction block 3638 close to the sliding ring 3634 is fixedly connected to the sliding ring 3634. The outer end of the third lead screw 3633 is rotatably connected to a support plate 3635. One end of the support plate 3635 close to the protective baffle 33 is fixedly connected to the protective baffle 33. During use, when the linkage mechanism 36 works, when the displacement mechanism 32 drives the protective baffle 33 to move, the transmission gear 362 at the lower end of the back side of the protective baffle 33 near the slider 324 moves accordingly. Since the rack 361 is fixed to the inner bottom of the installation housing 31 and the transmission gear 362 meshes with the rack 361, during the movement of the protective baffle 33, the transmission gear 362 rolls on the rack 361, not only achieving its own lateral displacement but also rotating around its axis. The rotation of the transmission gear 362 drives the first bevel gear 3631 fixed thereto to rotate synchronously. The first bevel gear 3631 meshes with the second bevel gear 3636, thereby driving the second bevel gear 3636 to rotate. The second bevel gear 3636 drives the third lead screw 3633 to rotate on the mounting bracket 3632. The sliding ring 3634 threadedly connected to the outer surface of the third lead screw 3633 moves linearly along the axial direction of the lead screw due to the rotation of the lead screw. The bottom of the sliding ring 3634 is connected to the cleaning mechanism 37, driving the cleaning mechanism 37 to move together to achieve the cleaning action of the touch operation screen 35. At the same time, the sliding ring 3634 is slidably connected to the guide rod 3637 through the correction block 3638. The guide rod 3637 is installed on the mounting bracket 3632. The correction block 3638 slides on the guide rod 3637 to assist in correcting the movement trajectory of the sliding ring 3634 to ensure its stable displacement. The support plate 3635 is fixed to the protective baffle 33 to provide support for the third lead screw 3633, ensuring the stability of the entire linkage process, so that when the protective baffle 33 moves, the cleaning mechanism 37 can clean the touch operation screen 35 efficiently and stably.

[0025] The implementation principle of the touch screen of the controller 34 for preventing accidental pressing of the ion source instrument status switching in the embodiment of the present application is as follows: during the use of the device, in view of the problem that the touch screen of the existing mass spectrometer is easily pressed by mistake, the present design introduces an intelligent protection system based on the recognition camera 39 and the motor lead screw transmission. The recognition camera 39 monitors the front area of the installation shell 31 in real time. When an unmanned state is detected, the system automatically triggers the first motor 322 to operate, and the first motor 322 drives the first lead screw 323 to rotate. The rotation of the lead screw pushes the slider 324 to slide in the guide rail 321, thereby driving the protective baffle 33 to smoothly cover the front of the installation shell 31, accurately blocking the touch operation screen 35, and effectively avoiding misoperation caused by accidental touch. When the recognition camera 39 detects that someone is approaching When the operation is ready, the signal is immediately fed back to the controller 34, and the controller 34 then controls the first motor 322 to reverse, drives the first screw rod 323 to rotate in the opposite direction, drives the slider 324 to slide in the opposite direction, and causes the protective baffle 33 to move laterally, completely exposing the touch screen 35, so that the operator can operate conveniently. After the operation is completed, when the recognition camera 39 confirms that the person has left, the first motor 322 is controlled to run in the opposite direction again, the first screw rod 323 drives the slider 324 to reset, and the protective baffle 33 covers the touch screen again, realizing full-process automated protection. This design minimizes the risk of mis-pressing, ensures the operational stability of the instrument during the detection process, avoids data deviation and instrument failure caused by mis-operation, and significantly improves the accuracy of the detection results. During the application of this device, considering the problem that the touch screen is easily contaminated by dust and human body fluids during manual operation, which affects the display accuracy, this technology constructs a cleaning system in which the transfer, linkage, and cleaning mechanism 37 work together. When the touch screen needs to be cleaned, the second motor 3252 is started. The second motor 3252 drives the driving gear 3253 to rotate. The driving gear 3253 drives the driven gear 3254 through meshing. The driven gear 3254 then drives the second lead screw 3256 to rotate. The rotation of the second lead screw 3256 pushes the displacement block 3255 to slide, causing the protective baffle 33 to move towards the touch operation screen 35, prompting the silicone scraper 377 to closely adhere to the outer surface of the touch operation screen 35. When the first motor 322 drives the first lead screw 323 to rotate, using the carefully designed linkage mechanism 36, the second lead screw 3256 is synchronously driven to drive the slider 324 to linearly displace, and the protective baffle 33 moves accordingly. During this process, the transmission gear 362 on the protective baffle 33 interacts with the rack 361. Driven by the rack 361, the transmission gear 362 not only realizes lateral displacement but also rotates synchronously. The rotation of the transmission gear 362 drives the first bevel gear 3631 and the second bevel gear 3636 to rotate in sequence. The second bevel gear 3636 then drives the third lead screw 3633 to rotate. The rotation of the third lead screw 3633 pushes the slip ring 3634 to laterally displace. The correction block 3638 connected to the top of the slip ring 3634 slides on the guide rod 3637 to assist in correcting the movement trajectory of the slip ring 3634 and ensure its stable displacement. The movement of the slip ring 3634 drives the silicone scraper 377 and the auxiliary scraper 379 to closely adhere to the touch operation screen 35 for scraping and cleaning. Due to the synchronous linkage of the first lead screw 323 and the third lead screw 3633, the silicone scraper 377 and the auxiliary scraper 379 can achieve horizontal and vertical inclined movement on the touch operation screen 35, fully covering the surface of the touch screen and achieving efficient cleaning. During the cleaning process, the compression spring 375 continuously acts to push the substrate 376, so that the silicone scraper 377 and the auxiliary scraper 379 always stably adhere to the touch operation screen 35, further enhancing the cleaning effect. In addition, when the silicone scraper 377 accumulates stains and needs to be replaced, just open the protective baffle 33 and twist the hand-twist screw 374 to disengage it from the mounting rail 371, then the carriage 372 can be easily pulled out from the mounting rail 371, quickly completing the replacement of the silicone scraper 377 and the auxiliary scraper 379, greatly improving the convenience of touch screen cleaning and maintenance, ensuring that the touch screen always maintains a clear display, and enhancing the fluency and reliability of instrument operation.

[0026] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
