Description

Technical Field

[0001] The present application relates to the technical field of quality inspection, and in particular to a human-machine interactive assembly quality inspection method for a longitude-latitude-type satellite-borne laser coarse pointing mechanism based on HCPS. Background Art

[0002] Satellites are important equipment for space exploration. The increase in human space activities has put forward higher requirements for information transmission in intersatellite communications. Satellite-borne laser communication has gradually replaced traditional microwave communications due to its advantages such as large data capacity, long transmission distance and strong anti-interference ability. Satellite-borne LCT mainly relies on CPM to maintain high pointing accuracy of laser beam acquisition, tracking and pointing (ATP). The large tracking field of view and low tracking bandwidth of CPM ensure that the laser beam enters the effective communication area, and uses the focal plane array (FPA) to establish an optical communication link. Among them, LCT stands for laser communication terminal, which is an important part of the satellite communication network, among which laser pointing accuracy is crucial to ensure high-quality communication. CPM stands for coarse pointing mechanism, which is a key mechanical component in LCT used to maintain laser pointing accuracy. During the movement of the satellite, the attitude of CPM must be adjusted in real time and its high rotational stability must be maintained to ensure the stability of LCT communication during the movement of the satellite.

[0003] The assembly quality of CPM has always been highly valued in academia and industry. Due to the limitations of the current level of automation, the assembly process of CPM relies heavily on manual labor. This leads to the lack of standardized procedures for many inspection steps that require manual measurement, especially the problem of axis swing that occurs during the assembly process. Although some studies have mentioned the significant impact of assembly on the pointing accuracy of CPM, no effective solution has been proposed. In order to solve the challenges of information sharing and feedback in the highly customized human-computer interaction assembly of CPM, and to improve the intelligence level and success rate of the assembly process, the human-computer collaboration method based on HCPS is considered to be a promising solution, but the human-computer interaction assembly method based on HCPS still lacks assembly specifications. The main reason is that CPM is a typical small-batch, customized satellite-borne product with different weights and structures. Therefore, designers and assemblers often spend a lot of time communicating with each other, resulting in low assembly efficiency and success rate.

[0004] like Figure 1 As shown in the figure, the latitude and longitude CPM is mainly composed of an axis system, a locking / release device, and some structural components (including a U-shaped frame, etc.). In addition, the CPM is also equipped with functional components such as a telescope and a Kude optical system. The axis system consists of a pitch axis and an azimuth axis that are perpendicular to each other. The motor rotates the axis through an angular contact ball bearing to control the direction of the laser.

[0005] The rotation accuracy of the axis directly affects the pointing accuracy of the laser. The rotation error of the axis system can be decomposed into three independent components: axial displacement error, radial swing error and angular motion error. Since the laser pointing is mainly controlled by the rotation of the turntable, the influence of axial displacement error and axial swing error on the angle can be ignored. Therefore, in CPM human-machine interactive assembly, quality inspection is mainly focused on the detection of angular motion error, also known as axis swing.

[0006] Technological advances have driven the industry's transition from manual manufacturing to automated manufacturing, while improving the intelligence of the system. So far, the industry focus has been on transforming experience-based operations into standardized processes that can be performed by machines, thereby improving the robustness of the system. A large amount of research and practice aims to optimize the use of human knowledge and skills while reducing dependence on human operators. However, due to cost considerations and technical limitations, the production of small batches of mechanical products still requires human assistance. Therefore, in recent years, there has been an increasing discussion about the role of humans in smart manufacturing. In our view, humans continue to play a vital role in industrial production for the following reasons:

[0007] 1. Ability to formulate comprehensive solutions: Whether it is to build a new production line, manufacture a new product, upgrade production equipment or adjust the process, systematic consideration must be carried out before the project is implemented. At present, the experience and knowledge of human engineers are irreplaceable when formulating comprehensive solutions. In other words, humans are still the leaders and creators in HCPS.

[0008] 2. Ability to handle anomalies and make decisions: Mechanical equipment and systems do not always operate stably as expected. When deviations from preset conditions or abnormalities occur, humans are required to find out the causes and determine appropriate countermeasures. Although artificial intelligence (AI) can assist data-driven reasoning and assist in decision-making, its ability to handle unexpected situations is still limited. Therefore, most manufacturing systems are designed to allow human decision makers to intervene and make the final decision.

[0009] 3. Ability to operate and execute: Although machines can reduce human labor intensity and perform repetitive tasks, they may not be suitable for certain scenarios, such as small batch or customized production. Human operation and execution are still important in the manufacturing process. The data measured and collected by human operators are important inputs to the manufacturing system. Summary of the invention

[0010] The purpose of this application is to provide a human-machine interactive assembly quality detection method for a coarse pointing mechanism based on HCPS, so as to propose a longitude-latitude-based spaceborne laser human-machine collaborative assembly quality detection framework based on HCPS through the mutual connection and interaction between human space, information space and physical space in the CPM assembly scenario.

The human-computer collaboration system can autonomously conduct incremental learning based on events or historical data to improve system adaptability.

[0015] In the assembly stage, when the rough pointing mechanism of the equipment is assembled in the physical space, the quality of all components is checked before assembly based on the support of the information space to ensure that all components meet the design requirements. When all components are in place, the assembly operation is performed manually or with the help of assembly tools according to the assembly standards;

[0016] During the inspection phase, the assembly quality of the human-machine interaction of the coarse pointing mechanism requires the assembler to set up a test workstation to offset the influence of gravity on the mechanical structure, measure multiple parameters, and determine the assembly quality according to corresponding inspection principles.

[0031] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0032] The specific implementation of the present application is further described in detail below in conjunction with the drawings and examples.

[0033] Laser communication terminal (LCT) is an important part of satellite communication network, in which laser pointing accuracy is crucial to ensure high-quality communication. The coarse pointing mechanism (CPM) is a key mechanical component in LCT for maintaining laser pointing accuracy. During satellite movement, the attitude of CPM must be adjusted in real time and its high rotational stability must be maintained, which mainly depends on the bearing system. Based on this, an embodiment of the present application provides a human-computer interaction assembly quality detection method for a longitude-latitude satellite-borne laser coarse pointing mechanism based on HCPS, which can be implemented by constructing a human-computer interaction assembly quality detection framework for a longitude-latitude satellite-borne laser coarse pointing mechanism based on HCPS. Specifically, the function and structure of the CPM of the method determine that its bearings must be able to withstand radial and axial loads, so angular contact bearings are generally used. Compared with other types of bearings such as deep groove ball bearings, angular contact bearings have smaller clearances, which enables the shaft system to be fixed in position and have higher rotational accuracy. The human-computer interaction assembly quality detection framework for the longitude-latitude satellite-borne laser CPM based on HCPS consists of four stages ( Figure 2 ).

[0034] First, the design stage.

[0035] The design of complex mechanical equipment originates from customer needs. For CPM, customers usually have rich professional backgrounds, which eliminates the challenges of explicitly expressing implicit requirements and exploring fuzzy requirements that are often faced in normal mechanical design. The design requirements of CPM are usually clear and constrained by specific indicators such as overall weight, platform torque, and pointing accuracy. These design requirements are then translated into specific functional requirements. For example, in order to meet the platform torque requirement, it is necessary to design or find a motor with high torque capability while meeting the weight constraint. However, high-torque motors often have low control accuracy, so it is necessary to integrate a fine pointing mechanism (FPM) with CPM. In addition to meeting functional requirements, the structural design of CPM must also consider specific application scenarios. A basic approach is to use the smallest structural unit to meet the requirements of the smallest functional unit. The decoupling process of requirements-function-structure in the design of complex mechanical products is a collaborative and iterative process involving continuous division and refinement. A lot of research has been done on this, but since it is beyond the scope of this paper, a detailed discussion will not be provided here.

[0036] Generally, the higher the degree of customization of a mechanical product, the greater the reliance on human involvement. In the context of CPM design, the knowledge and expertise of the designer and the preliminary verification performed constitute the key design resources. These human-driven processes belong to the human space in HCPS. In addition, design resources also include reference materials such as design manuals and design standards, which are usually provided in the form of physical or electronic documents, which belong to the information space. Similarly, the design solutions generated in the design phase only exist in the information space because they have not yet been transformed into physical entities. For the subsequent manufacturing and assembly of CPM components, a comprehensive and accurate design solution is the main guideline. The advantage of this approach is to establish consensus among multiple design teams in different disciplines and organizations. It helps to reduce communication and understanding barriers caused by vague terminology and inconsistent standards, thereby improving design efficiency and accuracy.

[0037] Second, the manufacturing stage.

[0038] Component manufacturing of complex products is often accomplished through collaboration among decentralized manufacturers. This approach is driven by significant differences between different components of complex products and considerations for supply chain stability, with the goal of better controlling project schedules and production costs. CPM's key components, such as locking / release devices, U-shaped frames, and bearings, are also produced through collaborative manufacturing. Component manufacturing requires cooperation between manufacturing personnel and manufacturing equipment, especially for customized components, where personnel skills are critical for equipment adjustment and debugging. Therefore, the skill level of manufacturing personnel has a significant impact on manufacturing quality and efficiency. In order to address this issue and improve the quality of human-machine collaboration, improvements can be made in three aspects:

[0039] 1) Evaluate the similarity of production tasks and the skill levels of manufacturing personnel in order to effectively match tasks with corresponding skills through strategy transfer.

[0040] 2) Incorporate AI technology and adopt more diverse interaction modes. For example, adopting a voice-based approach can simplify human-computer interaction, but this requires deep integration of technologies such as natural language processing and edge computing. In environments with high noise levels and inconvenient voice interaction, a simpler, user-friendly human-computer interface can be used, which requires a deep understanding of human operating habits.

[0041] 3) Continuously collect feedback from manufacturing personnel and implement adaptive strategies for human-machine interaction. This enables the human-machine collaborative system to autonomously conduct incremental learning based on events or historical data, thereby improving system adaptability. In addition, practical suggestions can be provided for the design phase to ensure that the design plan is consistent with equipment performance and human habits.

[0042] Within each manufacturer, manufacturing personnel operate equipment by issuing instructions. Highly automated and intelligent equipment also retrieves instructions directly from different information systems such as product lifecycle management (PLM) and manufacturing execution system (MES) and displays them to manufacturing personnel. In this process, the interconnection of human space, information space and physical space promotes the collaborative completion of component manufacturing tasks. For the purpose of quality traceability, process parameters are fully and detailedly recorded.

[0043] Third, the assembly stage.

[0044] The assembly process of CPM requires coordination between different personnel. Similar to the production stage, CPM assembly in the physical space still requires the support of humans and information space. Humans are responsible for checking the quality of all components before assembly to ensure that they meet the design requirements. Humans also need to determine whether the components are complete in case any components are missing. Once it is confirmed that all components are in place, assembly operations are performed manually or with the help of assembly tools according to assembly standards.

[0045] Fourth, the detection stage.

[0046] There are many aspects that affect the assembly quality of CPM, and this embodiment mainly focuses on the assembly of angular contact bearings. As mentioned above, the assembly quality of CPM bearings requires assemblers to set up a test workstation to offset the gravity effect of the mechanical structure. Multiple parameters need to be measured and the assembly quality is determined according to the corresponding detection principles. Auxiliary tools such as photoelectric collimators and plane reflectors are used in the assembly process, and all measuring tools need to be correctly positioned. The obtained measurement data is entered and stored in the assembly quality test plug-in, which has many quality assessment criteria built in. Therefore, in most cases, the system can automatically assist the inspector in determining whether the bearing assembly meets the specified requirements.

[0047] The operating mechanism of the HCPS-based longitude-latitude satellite-borne laser CPM human-machine interactive assembly quality inspection framework is mainly reflected in the cross-stage and cross-space interactions among the three spaces: human space, information space, and physical space. Figure 2 The main interaction lines are shown, and the serial numbers indicate their starting and ending points. It should be noted that the interaction lines in the figure only represent key interactions, not all interactions. In fact, the interactions between the three spaces are everywhere, and it is difficult to describe them with just "lines". Trying to depict all interactions will result in an extremely complex "network". Interactions occur spontaneously and are difficult to predetermine and comprehensively classify. However, in the CPM human-computer interaction design, manufacturing, assembly and quality inspection process, Figure 2 The interaction lines depicted in Figure 1 constitute the main skeleton of the network. The meanings of the interaction lines are listed in Table 1.

[0048] Table 1 Meaning of interaction lines

[0049]

[0050] Data, information, status and standards from different stages and spaces are continuously updated through interaction, with the goal of ensuring the assembly quality of CPM human-machine interaction within the HCPS framework. However, the elements in the HCPS-based framework discussed in this embodiment are relatively general and can be appropriately modified to match different industrial scenarios and goals. Regardless of how the framework changes, an appropriate interaction mechanism is the basis for the smooth and efficient operation of the system.

[0051] This embodiment applies the proposed HCPS-based human-machine interactive assembly detection method to a latitude-longitude CPM. The effectiveness of the proposed method is verified through the detection process of CPM shaft system swing. This process is mainly divided into three steps. First, the responsibilities of each party in the assembly process are divided from the perspective of HCPS; then, the bearings are assembled; finally, the quality parameters of the assembled CPM are measured, and the shaft system swing is calculated to see whether it meets the design requirements. The specific implementation steps are as follows:

[0052] Step 1, the assembly of the warp and weft CPM requires cooperation from multiple parties. Before the assembly begins, the responsibilities of different parties need to be clarified. After multiple rounds of iterative discussions between designers, manufacturers, assemblers, and inspectors, the main responsibilities are listed in Table 2.

[0053] Table 2 Roles and responsibilities of people

[0054]

[0055] Step 2, the assembly process begins. In order to ensure the pointing accuracy of CPM, there are two main assembly quality control points in the bearing assembly process: a) control of excess material in the process, and b) precision control of large thin-walled angular contact ball bearings.

[0056] For the control of excess material, the assembly process is carried out in a Class 1000 dust-free workshop. The relevant parts are cleaned and inspected, and the threaded parts are pre-assembled 3 times to ensure that there are no burrs. The excess parts of the bearing are cleaned with a microscope, and the preheated bearings are packaged and protected with a cleaning oven. All fastening screws are cleaned and inspected before and after gluing to ensure that there is no excess glue. For the precision control of the assembly of large thin-walled angular contact ball bearings, the deformation of related parts such as the outer pressure plate, the pitch axis and the azimuth axis are properly repaired to avoid thin-wall deformation.

[0057] Step 3: In order to determine whether the axis wobble of the CPM meets the pointing accuracy requirements, some quality parameters need to be measured and calculated. The optical components of the CPM need to be rotated once in both the forward and reverse directions to check whether there is a significant change in the laser pointing. During the actual measurement process, the inspector will record the light deviation every 15°. In addition, to ensure the validity of the measurement, the test will be repeated. Figure 3 Visualization of the measurement results of a CPM human-machine interaction assembly quality check. Based on the results automatically calculated by the plug-in, this quality check shows that the assembly quality meets the requirements.

[0058] The assembly of small batch customized mechanical products has always been a hot topic in academia and industry. As the structure of mechanical products becomes increasingly complex, more and more responsible parties are involved in the entire life cycle of their design, production, assembly and operation. For satellite-borne LCT, the assembly accuracy of CPM will seriously affect the pointing accuracy of the laser communication system. Due to the limitations of cost and current technical level, the assembly process of CPM still relies heavily on humans to formulate assembly plans, perform assembly operations and check assembly quality. In order to give full play to the potential of human intelligence and labor resources, this embodiment proposes a human-computer interaction assembly quality detection framework based on HCPS. The proposed method is applied to a longitude-latitude CPM. The results show that the method is very consistent with human habits, the probability of assembly errors is greatly reduced, and the pointing accuracy can be well guaranteed.

[0059] The above implementation modes are only used to illustrate the present application, and are not intended to limit the present application. Ordinary technicians in the relevant technical field may make various changes and modifications without departing from the spirit and scope of the present application. Therefore, all equivalent technical solutions also belong to the scope of the present application, and the scope of patent protection of the present application shall be limited by the claims.
