Description

Technical Field

[0001] This application relates to the field of quality inspection technologies, and particularly to a method for human-computer interaction assembly quality inspection of a theodolite-type spaceborne laser coarse pointing mechanism based on HCPS. Background Art

[0002] Satellites are important equipment for space exploration. The increasing human space activities have put forward higher requirements for information transmission in inter-satellite communication. Due to its advantages such as large data capacity, long transmission distance, and strong anti-interference ability, spaceborne laser communication has gradually replaced traditional microwave communication. Spaceborne LCT mainly relies on CPM to maintain high pointing accuracy for 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 establish an optical communication link using a focal plane array (FPA). Among them, LCT represents the laser communication terminal, which is an important part of the satellite communication network, and the laser pointing accuracy is crucial for ensuring high-quality communication. CPM represents the coarse pointing mechanism, which is a key mechanical component in LCT for maintaining laser pointing accuracy. During the satellite movement, it is necessary to adjust the attitude of CPM in real time and maintain its high rotational stability to ensure the communication stability of LCT during the satellite movement.

[0003] The assembly quality of CPM has always been highly regarded in academia and industry. Due to the limitations of the current automation level, the assembly process of CPM largely relies on manual labor. This results in a lack of standardized procedures for many inspection steps that require manual measurement, especially the problem of shaft swing during the assembly process. Although some studies have mentioned the significant impact of assembly on the pointing accuracy of CPM, no effective solutions have been proposed. To address the challenges of information sharing and feedback in the highly customized human-computer interaction assembly of CPM, and to improve the intelligent level and success rate of the assembly process, the human-machine collaboration method based on HCPS is considered 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 and 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] As Figure 1 shown, the theodolite-type CPM mainly consists of a shaft system, a locking / releasing device, and some structural components (including U-shaped frames, etc.). In addition, CPM is also equipped with functional components such as a telescope and a Coudé optical system. The shaft system consists of a pitch axis and an azimuth axis that are perpendicular to each other. The motor rotates the shaft through angular contact ball bearings to control the laser direction.

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

[0006] Technological progress has promoted the transformation of the industry from manual manufacturing to automated manufacturing, while improving the intelligence level of the system. So far, the industry focus has been on transforming experience-based operations into standardized processes that can be executed by machines, thereby improving the robustness of the system. A large amount of research and practice aims to optimize the utilization of human knowledge and skills while reducing the dependence on human operators. However, due to cost considerations and technological limitations, the production of small-batch mechanical products still requires human assistance. Therefore, in recent years, the discussion about the role of humans in intelligent manufacturing has increased. In our view, humans continue to play a crucial role in industrial production for the following reasons:

[0007] 1. Ability to formulate comprehensive solutions: Whether it is establishing a new production line, manufacturing new products, upgrading production equipment, or adjusting processes, systematic consideration must be carried out before project implementation. Currently, 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 there are deviations or anomalies from the preset conditions, humans are needed to find out the reasons 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 the labor intensity of humans and perform repetitive tasks, they may not be suitable for some scenarios, such as small-batch or customized production. The operation and execution of humans are still of great significance 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 quality inspection method for the human-machine interaction assembly of a coarse pointing mechanism based on HCPS, so as to propose a quality inspection framework for the theodolite-type spaceborne laser human-machine collaborative assembly based on HCPS through the interconnection and interaction between the human space, information space, and physical space in the CPM assembly scenario.

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

[0032] The following combines the accompanying drawings and embodiments to further describe in detail the specific implementation manners of the present application.

[0033] The laser communication terminal (LCT) is an important part of the satellite communication network, and the laser pointing accuracy is crucial for ensuring high-quality communication. The coarse pointing mechanism (CPM) is a key mechanical component in the LCT for maintaining the laser pointing accuracy. During the movement of the satellite, it is necessary to adjust the attitude of the CPM in real time and maintain its high rotational stability, which mainly depends on the bearing system. Based on this, the embodiments of the present application provide a method for detecting the human-machine interaction assembly quality of a theodolite-type spaceborne laser coarse pointing mechanism based on HCPS. This method can be implemented by constructing a human-machine interaction assembly quality detection framework for a theodolite-type spaceborne laser coarse pointing mechanism based on HCPS. Specifically, the function and structure of the CPM of this method determine that its bearings must be able to withstand radial and axial loads, so angular contact bearings are usually used. Compared with other types of bearings such as deep groove ball bearings, the angular contact bearings have smaller clearances, which enables the shafting to fix the position and has higher rotational accuracy. The human-machine interaction assembly quality detection framework for a theodolite-type spaceborne 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 requirements. For CPM, customers usually have a rich professional background, which eliminates the challenges of explicitly expressing implicit requirements and exploring fuzzy requirements often faced in normal mechanical design. The design requirements of CPM are usually clear and constrained by specific metrics such as overall weight, platform torque, and pointing accuracy. These design requirements are then translated into specific functional requirements. For example, to meet the requirement of platform torque, a motor with high torque capacity needs to be designed or found, while also meeting the weight constraint. However, high-torque motors often have lower control accuracy, so a fine pointing mechanism (FPM) needs to be integrated with the 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 units to meet the requirements of the smallest functional units. The decoupling process of requirements - function - structure in complex mechanical product design is a collaborative and iterative process involving continuous partitioning and refinement, and a large amount of research has been done on this, but since it is beyond the scope of this article's work, no detailed discussion will be provided here.

[0036] Generally, the higher the degree of customization of mechanical products, the greater the dependence on human participation. In the context of CPM design, the knowledge and professional skills of designers and the preliminary verification carried out constitute 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 physical or electronic document forms and belong to the information space. Similarly, the design schemes generated in the design stage only exist in the information space because they have not been transformed into physical entities. For the subsequent manufacturing and assembly of CPM components, a comprehensive and accurate design scheme is the main guideline. The advantage of this approach is to build consensus among multiple design teams in different disciplinary fields and organizations. It helps to reduce communication and understanding barriers caused by ambiguous terms and inconsistent standards, thus improving design efficiency and accuracy.

[0037] Second, the manufacturing stage.

[0038] The manufacturing of components of complex products is usually completed through the collaboration of decentralized manufacturers. This approach is driven by the significant differences between different components of complex products and the consideration of supply chain stability, aiming to better control the project schedule and production costs. The key components of CPM, such as locking / releasing devices, U-shaped frames, and bearings, are also produced through collaborative manufacturing methods. Component manufacturing requires cooperation between manufacturing personnel and manufacturing equipment. Especially for customized components, personnel skills are crucial for equipment adjustment and debugging. Therefore, the skill level of manufacturing personnel has a significant impact on manufacturing quality and efficiency. To solve this problem and improve the quality of human - machine collaboration, improvements can be made from three aspects:

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

[0040] 2) Incorporate AI technology and adopt more diverse interaction modes. For example, using a voice-based method can simplify human-machine interaction, but this requires deep integration of technologies such as natural language processing and edge computing. In an environment with a high noise level where voice interaction is inconvenient, a simpler and user-friendly human-machine interface can be used, which requires a profound understanding of human operation habits.

[0041] 3) Continuously collect feedback from manufacturing personnel and implement an adaptive strategy for human-machine interaction. This enables the human-machine collaboration system to autonomously perform incremental learning based on events or historical data, thereby improving system adaptability. In addition, practical suggestions can be provided for the design stage to ensure that the design scheme conforms to equipment performance and human habits.

[0042] Within each manufacturer, manufacturing personnel operate equipment by issuing instructions. Highly automated and intelligent equipment also directly retrieves instructions 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 the human space, information space, and physical space promotes the collaborative completion of component manufacturing tasks. For the purpose of quality traceability, process parameters are comprehensively and detailedly recorded.

[0043] Third, the assembly stage.

[0044] The assembly process of CPM requires coordination among different personnel. Similar to the production stage, the CPM assembly carried out in the physical space still requires the support of the human and information spaces. Humans are responsible for inspecting 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, the assembly operation is carried out manually or with the aid of assembly tools according to the assembly standards.

[0045] Fourth, the inspection stage.

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

[0047] The operating mechanism of the HCPS-based theodolite-type spaceborne laser CPM human-machine interaction assembly quality detection framework is mainly reflected in the cross-stage and cross-space interactions among the three spaces of the 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 among the three spaces are ubiquitous, and it is difficult to describe them only with "lines". Trying to depict all interactions will result in an extremely complex "network". Interactions occur spontaneously and are difficult to pre-determine and comprehensively classify. However, in the process of CPM human-machine interaction design, manufacturing, assembly, and quality detection, Figure 2 the interaction lines depicted in it constitute the main framework of the network. The meanings represented by the interaction lines are listed in Table 1.

[0048] Table 1 Meanings of Interaction Lines

[0049]

[0050] Data, information, as well as status and standards from different stages and spaces are continuously updated through interactions, aiming to ensure 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 objectives. No matter how the framework changes, an appropriate interaction mechanism is the basis for the stable and efficient operation of the system.

[0051] This embodiment applies the proposed HCPS-based human-machine interaction assembly detection method to a theodolite-type CPM. The effectiveness of the proposed method is verified through the detection process of the CPM axis system swing. This process is mainly divided into three steps. First, divide the responsibilities of all parties in the assembly process from the perspective of HCPS; then, assemble the bearings; finally, measure the quality parameters of the assembled CPM and calculate whether the axis system swing meets the design requirements. The specific implementation steps are as follows:

[0052] Step 1, the assembly of the theodolite-type CPM requires the cooperation of multiple parties. Before the assembly starts, it is necessary to clarify the responsibilities of different parties. After multiple rounds of iterative discussions among 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. To ensure the pointing accuracy of the CPM, there are two main assembly quality control points during the bearing assembly process: a) control of excess materials during the process, b) accuracy control of large thin-walled angular contact ball bearings.

[0056] For the control of excess materials, the assembly process is carried out in a Class 1000 cleanroom. The relevant components are cleaned and inspected. The threaded components are pre-assembled 3 times to ensure no burrs. The excess parts of the bearings are cleaned using a microscope, and the preheated bearings are packaged and protected using a cleaning oven. All fastening screws are cleaned and inspected before and after dispensing to ensure no excess glue. For the precision control of the assembly of large thin-walled angular contact ball bearings, the relevant components such as the deformation of the outer pressure plate, the pitching axis, and the azimuth axis are appropriately repaired to avoid thin-wall deformation.

[0057] Step 3, in order to determine whether the shaft swing 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 one full circle in each of the forward and reverse directions to check whether there is an obvious change in the laser pointing. During the actual measurement process, the inspector will record the light offset every 15°. In addition, in order to ensure the effectiveness of the measurement, the test will be repeated once. Figure 3 Visualized the measurement results of a CPM human-machine interaction assembly quality inspection. According to the results automatically calculated by the plug-in, this quality inspection 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 spaceborne LCT, the assembly accuracy of the CPM will seriously affect the pointing accuracy of the laser communication system. Due to cost and current technical level limitations, the assembly process of the CPM still largely relies on humans to formulate assembly plans, execute assembly operations, and inspect assembly quality. In order to give full play to the potential of humans in terms of intellectual and labor resources, this embodiment proposes a human-machine interaction assembly quality detection framework based on HCPS. Applying the proposed method to a theodolite-type CPM, the results show that the method is very in line with human habits, the probability of assembly errors is greatly reduced, and the pointing accuracy can be well guaranteed.

[0059] The above embodiments are only used to illustrate the present application and are not intended to limit the present application. Those of ordinary skill in the relevant technical fields can also 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. The patent protection scope of the present application shall be defined by the claims.
