Abstract

This invention discloses a detachable housing system and non-destructive maintenance method for precision instruments, relating to the field of precision instrument technology. The system includes a mounting base, an electronic interface integrated board, and a protective housing.

Description

Technical Field

[0001] This invention relates to the field of precision instrument technology, and in particular to a detachable housing system for precision instruments and a non-destructive maintenance method. Background Technology

[0002] Precision instruments, especially those with nanometer- or even atomic-level measurement capabilities such as atomic force microscopes, are indispensable tools for modern scientific research and high-end manufacturing. The core value of these instruments lies in their ultra-high measurement accuracy and stability. They typically integrate core modules such as a probe-sample interaction detection system, a high-precision scanning and positioning system driven by piezoelectric ceramics, and a complex optical or electrical feedback control system. The mechanical alignment, electrical parameter calibration, and software operating point of these modules collectively determine the instrument's ultimate performance. Therefore, maintaining the absolute stability of the internal core modules in terms of physical position and electrical state is a fundamental prerequisite for ensuring the reliability and repeatability of measurement data.

[0003] However, instruments inevitably require maintenance or operational intervention during long-term operation, such as cleaning optical components, replacing probes, and inspecting internal connections. In existing technologies, there is a strong physical coupling between the protective casing and the internal structure: on the one hand, external electrical interfaces are often directly installed or cables are connected to the casing, making them prone to pulling, bending, or even damaging internal precision cables and connectors during disassembly; on the other hand, the casing often serves as a load-bearing or positioning reference, and its disassembly process may directly or indirectly disturb the mechanical fixation of the core functional modules below. This strong structural correlation makes basic maintenance operations themselves a high-risk process that introduces uncontrollable micro-disturbances, leading to mechanical misalignment or electrical parameter drift, seriously threatening instrument performance. Summary of the Invention

[0004] This invention provides a detachable housing system and a non-destructive maintenance method for precision instruments, which can solve the problems in the prior art where the protective housing and the internal structure are strongly physically coupled, making basic maintenance actions themselves introduce uncontrollable micro-disturbances, leading to mechanical offsets or electrical parameter drift.

[0005] A detachable housing system for precision instruments includes a mounting base, an electronic interface integrated board, and a protective housing. The precision instrument is mounted on the mounting base. The electronic interface integrated board is connected to the mounting base. The protective housing is detachably connected to the mounting base. The protective housing has a splicing notch adapted to the shape of the electronic interface integrated board. The electrical connection terminals of the electronic interface integrated board are not located on the protective housing.

[0006] The present invention provides a detachable housing system for precision instruments, which, compared with the prior art, has, but is not limited to, the following beneficial effects: This detachable housing system for precision instruments achieves physical decoupling between the electrical interface and the protective housing by integrating all external electrical connections onto an electronic interface integrated board and fixing it to the mounting base. Disassembly of the housing only requires disconnecting the housing itself, without pulling or bending any internal cables or connectors, thus eliminating the possibility of electrical connection damage or signal interference caused by such operations. The core load-bearing and positioning reference of the entire system is the mounting base, on which all core modules of the precision instruments are fixed. The protective housing is only externally assembled and detachably connected via a splicing notch and does not serve as the installation or positioning reference for the precision instruments. Therefore, the process of disassembling the protective housing itself does not generate any direct or indirect stress transmission or disturbance to the mechanical fixation of the mounting base and the precision instruments on it, perfectly maintaining the existing mechanical calibration state of the instruments.

[0007] Furthermore, a door panel is rotatably connected to the protective shell via a hinge, and a viewing window is provided on the door panel.

[0008] Furthermore, the mounting base plate is provided with a plurality of first mounting holes and second mounting holes. The first mounting holes are used to mount precision instruments, and the second mounting holes are used to mount protective shells. The edge of the mounting base plate is provided with a guide structure, and the inner side of the protective shell is provided with a corresponding positioning step.

[0009] Furthermore, the electronic interface integrated board includes a board body, the back of the board body has multiple slots, the bottom of the board body is detachably connected to the mounting base plate by a first bolt, and the top of the board body is detachably connected to the protective shell by a second bolt.

[0010] Furthermore, the protective shell is an integral structure, and the protective shell is detachably connected to the mounting base plate around its perimeter by a third bolt. The inner wall of the protective shell is provided with reinforcing ribs.

[0011] A non-destructive maintenance method for a detachable housing system for precision instruments, based on the aforementioned detachable housing system for precision instruments, includes the following steps: S1, disconnecting the protective housing from the mounting base and the electronic interface integration board, and removing the entire protective housing to expose the core area of ​​the precision instrument; S2, performing the required maintenance operations while the mounting base, the electronic interface integration board, and the precision instrument remain fixed; S3, reinstalling the protective housing onto the mounting base, aligning the splicing notch with the electronic interface integration board, and then fixing the connection.

[0012] Furthermore, in response to the maintenance trigger signal, the precision instrument is controlled to enter the standby state, and each core module of the precision instrument is automatically controlled to enter the safe state. Simultaneously, all current working parameters are read, and a snapshot of the pre-maintenance state with timestamp and verification code is generated and stored in non-volatile memory.

[0013] Furthermore, after step S3 is executed, the snapshot of the state before maintenance is retrieved, the current working parameters of the precision instrument after maintenance are obtained, and compared with the snapshot of the state before maintenance; if all parameter differences are within the preset tolerance threshold, the state recovery operation is executed to restore the system parameters to the state recorded in the snapshot of the state before maintenance.

[0014] Furthermore, if a parameter difference is found to exceed the tolerance threshold, an anomaly handling process is triggered. The process includes at least one of the following operations: if the out-of-tolerance parameter is related to the safe operation of the equipment, the precision instrument is controlled to enter a safety lock or standby state; if the out-of-tolerance parameter is related to measurement accuracy, the precision instrument is restricted from entering a high-precision working mode that depends on the parameter; and diagnostic prompts containing out-of-tolerance parameter identification and maintenance suggestions are generated and output.

[0015] Furthermore, after triggering the aforementioned anomaly handling process, the system provides at least one recovery path, which includes: an automatic monitoring path: continuously monitoring out-of-tolerance parameters, and automatically releasing the corresponding restriction or lock state when they return to within a preset tolerance threshold; a manual verification path: providing a user operation interface to receive manual verification instructions, and releasing the abnormal state after successful verification; and a guided calibration path: initiating a special calibration program for out-of-tolerance parameters, guiding the user to complete the calibration, updating system parameters based on the calibration results, and releasing the abnormal state.

[0024] like Figure 1-3 As shown in the figure, an embodiment of the present invention provides a detachable housing system for precision instruments, including a mounting base plate 1, an electronic interface integrated board 2, and a protective housing 3. A precision instrument 8 is mounted on the mounting base plate 1; the electronic interface integrated board 2 is connected to the mounting base plate 1; the protective housing 3 is detachably connected to the mounting base plate 1, and the protective housing 3 has a splicing notch 4 that matches the shape of the electronic interface integrated board 2; wherein, the electrical connection terminals of the electronic interface integrated board 2 are not located on the protective housing 3.

[0025] In this embodiment, by integrating all external electrical connections onto the electronic interface integration board 2 and fixing it to the mounting base plate 1, physical decoupling between the electrical interface and the protective housing 3 is achieved. When disassembling the housing, only the protective housing 3 itself needs to be disconnected; no internal cables or connectors are pulled or bent, eliminating electrical connection damage or signal interference caused by such operations. The core load-bearing and positioning reference of the entire system is the mounting base plate 1, on which all core modules of the precision instruments 8 are fixed. The protective housing 3 is only externally assembled and detachably connected through the splicing notch 4 and does not serve as the installation or positioning reference for the precision instruments 8. Therefore, the process of disassembling the protective housing 3 itself will not cause any direct or indirect stress transmission or disturbance to the mechanical fixation state of the mounting base plate 1 and the precision instruments 8 on it, perfectly maintaining the existing mechanical calibration state of the instruments. Through the physical design of modularly separating the protective and electrical interface functions, routine maintenance operations are no longer a high-risk process, thus ensuring the long-term performance stability of the precision instruments.

[0026] The protective shell 3 can be either an integrated structure or a split structure.

[0027] like Figure 1 and Figure 2 As shown, a door panel 6 is rotatably connected to the protective shell 3 via a hinge 5, and a viewing window 7 is provided on the door panel 6.

[0028] In this embodiment, without disassembling the entire protective housing 3, simply opening the door panel 6 allows direct observation of the internal condition through the visualization window 7, enabling routine and frequent operations such as replacing test samples, cleaning the observation window, or making simple fine adjustments. This reduces the time consumption and operational complexity associated with completely disassembling the housing.

[0029] like Figure 3 , Figure 5 and Figure 6 As shown, the mounting base plate 1 has a first mounting hole 101 and a second mounting hole 102. The first mounting hole 101 is used to mount the precision instrument 8, and the second mounting hole 102 is used to mount the protective shell 3. The edge of the mounting base plate 1 is provided with a guide structure 9, and the inner side of the protective shell 3 is provided with a positioning step 10.

[0030] In this embodiment, the core components of the electronic interface integration board 2, the protective housing 3, and the precision instrument 8 can be installed through multiple first mounting holes 101 and second mounting holes 102. The guide structure 9, in conjunction with the positioning step 10, provides clear physical guidance during the installation of the protective housing 3, ensuring its precise placement along a predetermined path. This allows for quick and accurate alignment of the splicing notch 4 on the protective housing 3 with the electronic interface integration board 2, greatly simplifying the assembly process.

[0031] like Figure 1 and Figure 4 As shown, the electronic interface integrated board 2 includes a board body 201. Multiple slots 202 are provided on the back of the board body 201. The bottom of the board body 201 is detachably connected to the mounting base plate 1 by a first bolt 203, and the top of the board body 201 is detachably connected to the protective shell 3 by a second bolt 204.

[0032] In this embodiment, the board 201 serves as the core load-bearing structure of the electronic interface integration board 2, providing a stable mounting base for various electrical interface components and ensuring the reliability of electrical connections. The multiple slots 202 on the side of the board 201 can be used to organize various electrical cables, enabling the classification, storage, and avoidance of cables, preventing poor contact or damage caused by cable tangling or squeezing, and improving the rationality of the structural layout.

[0033] Specifically, the bottom of the board 201 is detachably connected to the mounting base plate 1 by the first bolt 203, and the top is detachably connected to the protective shell 3 by the second bolt 204. This dual detachable connection structure not only achieves a stable fixation between the electronic interface integrated board 2 and the mounting base plate 1, ensuring that it remains in a stable position with the mounting base plate 1, but also allows the electronic interface integrated board 2 to be flexibly disassembled according to actual needs when the protective shell 3 is disassembled for maintenance, making it convenient to inspect and repair itself.

[0034] like Figure 1 and Figure 5 As shown, the protective shell 3 is detachably connected to the mounting base plate 1 around its perimeter by the third bolt 11, and the inner wall of the protective shell 3 is provided with reinforcing ribs 12.

[0035] In this embodiment, the protective shell 3 provides all-around protection for the precision instrument 8 on the mounting base plate 1, effectively isolating it from external dust, impurities, minor collisions, and other interference, ensuring the normal operation of the precision instrument 8. The protective shell 3 is detachably connected to the mounting base plate 1 via a third bolt 11, allowing staff to quickly remove the protective shell 3 by disassembling the third bolt 11 as needed for maintenance, significantly improving the flexibility and efficiency of maintenance operations. By setting reinforcing ribs 12 inside the protective shell 3, the overall structural strength and rigidity of the protective shell 3 can be significantly enhanced, preventing the protective shell 3 from deforming due to insufficient strength. This avoids the deformed shell from squeezing or touching the internal precision instrument 8 or electronic interface integrated board 2, extending the service life of the protective shell 3 and further ensuring the structural stability of the entire system and the operational safety of the precision instrument 8.

[0036] like Figure 7As shown, a non-destructive maintenance method for a detachable housing system for precision instruments, based on the detachable housing system for precision instruments, includes the following steps: S1, disconnecting the protective housing 3 from the mounting base plate 1 and the electronic interface integration board 2, and removing the protective housing 3 as a whole to expose the core area of ​​the precision instrument 8; S2, performing the required maintenance operation while the mounting base plate 1, the electronic interface integration board 2 and the precision instrument 8 remain fixed; S3, reinstalling the protective housing 3 onto the mounting base plate 1, aligning the splicing notch 4 with the electronic interface integration board 2, and then fixing the connection.

[0037] In this embodiment, by disconnecting the protective housing 3 from the mounting substrate 1 and the electronic interface integration board 2, the entire protective housing 3 is removed to expose the core area of ​​the precision instrument 8. This approach leverages the detachable connection between the protective housing 3 and the mounting substrate 1 to achieve rapid disassembly of the housing. Furthermore, the independent arrangement of the electronic interface integration board 2 and the protective housing 3 avoids pulling or touching related components of the electronic interface integration board 2 during the disassembly of the protective housing 3, thus reducing the risk of electrical damage from the outset. Maintenance operations are performed while the mounting substrate 1, the electronic interface integration board 2, and the precision instrument 8 remain fixed, eliminating the problem of disturbing core functional modules during housing disassembly as is present in existing technologies. To prevent mechanical misalignment or electrical parameter drift, ensure the performance stability of the precision instrument 8, and guarantee the safety of maintenance operations such as cleaning optical components and replacing probes; the protective shell 3 is reinstalled onto the mounting base plate 1, and the splicing notch 4 is aligned and fixed with the electronic interface integrated board 2. Relying on the matching structure between the splicing notch 4 and the electronic interface integrated board 2, the protective shell 3 is accurately reset and installed, avoiding the shell from squeezing internal components due to installation deviation. At the same time, the fixing is completed quickly, further improving maintenance efficiency. The entire process achieves non-destructive maintenance of the precision instrument 8 and related components, greatly reducing the risk of failure during maintenance and extending the service life of the instrument.

[0038] like Figure 7 and Figure 8 As shown, in response to the maintenance trigger signal, the precision instrument 8 is controlled to enter the standby state, and each core module of the precision instrument 8 is automatically controlled to enter the safe state. At the same time, all current working parameters are read, and a snapshot of the pre-maintenance state with timestamp and verification code is generated and stored in non-volatile memory.

[0039] In this embodiment, upon responding to the maintenance trigger signal, the precision instrument 8 is first controlled to enter a standby state, and then each core module of the precision instrument 8 is automatically controlled to enter a safe state. This can preemptively cut off the high-risk operation links of the core modules of the precision instrument 8, avoiding component damage and parameter disorder caused by instrument misoperation, accidental start-up, or the precision instrument 8 being in operation during the maintenance process. This ensures non-destructive maintenance of the precision instrument 8 from the source of operation. At the same time, all current operating parameters of the precision instrument 8 are read synchronously, and a snapshot of the pre-maintenance state with a timestamp and verification code is generated and stored in non-volatile memory. This not only completely preserves the operating parameter benchmark of the precision instrument 8 before maintenance, providing an accurate basis for parameter comparison and state recovery after maintenance, avoiding the problem of untraceable and difficult-to-calibrate parameter deviations after maintenance, but also ensures the authenticity and integrity of the parameter snapshot through timestamps and verification codes, preventing parameters from being tampered with or lost. This further ensures that the precision instrument 8 can be accurately restored to the stable operating state before maintenance after maintenance, effectively avoiding electrical parameter drift caused by maintenance operations, and comprehensively protecting the core performance of the precision instrument 8.

[0040] like Figure 7 and Figure 8 As shown, after step S3 is executed, the snapshot of the state before maintenance is retrieved, the current working parameters of the precision instrument 8 after maintenance are obtained, and compared with the snapshot of the state before maintenance; if all parameter differences are within the preset tolerance threshold, the state recovery operation is executed to restore the system parameters to the state recorded in the snapshot of the state before maintenance.

[0041] In this embodiment, after the protective housing 3 is reset and installed, the previously stored snapshot of the state before maintenance is retrieved, and the current working parameters of the precision instrument 8 after maintenance are obtained and compared. This allows for quick verification of whether the maintenance operation has disturbed the operating parameters of the precision instrument 8, timely investigation of potential parameter deviations, and provides a scientific basis for subsequent state adjustments. If all parameter differences are within the preset tolerance threshold, a state recovery operation is performed to restore the system parameters to the state recorded in the snapshot before maintenance. This ensures that the precision instrument 8 quickly returns to its stable operating state before maintenance, effectively avoiding problems such as decreased measurement accuracy and abnormal operation caused by parameter deviations after maintenance. It not only relies on the complete parameter benchmark of the snapshot before maintenance to achieve accurate reset of the parameters of the precision instrument 8, but also further consolidates the effect of non-destructive maintenance, comprehensively ensuring that the core performance of the precision instrument 8 is not adversely affected by the maintenance operation, and ensuring its long-term stable operation.

[0042] like Figure 7 and Figure 8As shown, if a parameter difference is found to exceed the tolerance threshold, an abnormal handling process is triggered. The process includes at least one of the following operations: a) If the out-of-tolerance parameter is related to the safe operation of the equipment, the precision instrument 8 is controlled to enter a safety lock or standby state; b) If the out-of-tolerance parameter is related to the measurement accuracy, the precision instrument 8 is restricted from entering a high-precision working mode that depends on the parameter; c) A diagnostic prompt message containing the out-of-tolerance parameter identifier and maintenance suggestions is generated and output.

[0043] In this embodiment, the anomaly handling process includes at least one operation that specifically addresses the potential hazards of out-of-tolerance parameters. In operation a, if the out-of-tolerance parameter is related to equipment operation safety, the precision instrument 8 is controlled to enter a safety lock or standby state, which can quickly cut off the safety risk link and avoid damage to the core components of the precision instrument 8, malfunction, or even safety accidents caused by parameter out-of-tolerance, thus achieving comprehensive protection for the precision instrument 8 from a safety perspective. In operation b, if the out-of-tolerance parameter is related to measurement accuracy, the precision instrument 8 is restricted from entering a high-precision working mode that depends on the parameter, which can prevent the measurement results from being distorted due to parameter deviation, ensure the normal operation of the precision instrument 8 in non-high-precision working scenarios, and avoid the generation of erroneous measurement data, thus balancing the instrument's practicality and measurement reliability. In operation c, diagnostic prompts containing out-of-tolerance parameter identification and maintenance suggestions are generated and output, which can quickly guide staff to locate the root cause of the out-of-tolerance, clarify the direction of subsequent adjustments, greatly reduce the difficulty of fault diagnosis and parameter calibration, shorten maintenance time, ensure that the precision instrument 8 returns to normal operation as soon as possible, further improve the closed loop of non-destructive maintenance, and comprehensively avoid the adverse effects of parameter out-of-tolerance on the performance and operational safety of the precision instrument 8.

[0044] like Figure 7 and Figure 8 As shown, after the exception handling process is triggered, the system provides at least one recovery path, which includes: an automatic monitoring path: continuously monitoring out-of-tolerance parameters, and automatically releasing the corresponding restrictions or lock status when they return to within the preset tolerance threshold; a manual verification path: providing a user operation interface to receive manual verification instructions, and releasing the exception status after successful verification; and a guided calibration path: starting a special calibration program for out-of-tolerance parameters, guiding the user to complete the calibration, updating the system parameters based on the calibration results, and releasing the exception status.

[0045] In this embodiment, the automatic monitoring path continuously monitors out-of-tolerance parameters. When these parameters return to within the preset tolerance threshold, the corresponding restrictions or lockouts are automatically lifted without manual intervention. This reduces labor costs and enables real-time response and rapid reset of out-of-tolerance parameters, preventing the precision instrument 8 from being in an abnormal restricted state for an extended period due to untimely manual operation, thus ensuring instrument operating efficiency. The manual verification path provides a user interface, receives manual verification commands, and lifts the abnormal state after verification. This meets the needs of staff for proactive verification and rapid unlocking based on actual maintenance scenarios, improving operational flexibility and adapting to various complex maintenance conditions, ensuring that the precision instrument 8 can promptly return to normal operation. The guided calibration path can initiate a special calibration program for out-of-tolerance parameters, guiding users to complete calibration and update system parameters based on the calibration results to lift the abnormal state. This accurately locates the root cause of the out-of-tolerance and completes targeted calibration, ensuring that the parameters of the precision instrument 8 return to the standard range. This not only ensures the measurement accuracy and operational safety of the precision instrument 8 but also reduces the difficulty of user calibration operations, further improving the closed-loop management of anomaly handling and comprehensively avoiding the adverse effects of out-of-tolerance parameters on the long-term stable operation of the precision instrument 8.

[0046] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
