Description

Technical Field

[0001] This application relates to the field of optical measurement technology, and further to a collimator assembly and adjustment device and system. Background Technology

[0002] As one of the main components of optical measuring instruments, the collimator's calibration accuracy directly affects the testing accuracy of the optical system. Since the collimator calibration process involves precisely positioning the reticle's scale face to the objective lens's focal plane, related techniques often utilize the image of an object at infinity on the focal plane, determining the focal plane by the image's position, or determining the focal plane's position based on the characteristics of the image at infinity.

[0003] Currently, the calibration of transmission collimators mainly employs the autocollimation method. This involves combining the eyepiece with a reticle illumination device with the reticle of the transmission collimator to form an autocollimating eyepiece. This eyepiece, together with the objective lens of the transmission collimator, constitutes an autocollimating front mirror. By aligning this autocollimating front mirror with a standard plane mirror and adjusting the scale on the reticle and the focus of the reflected image, autocollimation can be achieved, thus completing the calibration. However, for large-aperture infrared applications, such as long-wave infrared transfer instruments, thermal imager parameter testing systems, and giant aperture telescopes for astronomical observation, transmission collimators are no longer suitable. Reflection collimators are non-rotationally symmetric systems, and the spin of off-axis mirrors around the optical axis must be considered during assembly and calibration. Furthermore, the use of reflection collimators relies on their optical characteristics (such as no central obstruction, high resolution, large field of view, and low aberrations). In the industry, interferometers are often chosen as autocollimating eyepieces for the assembly and calibration of these high-precision collimators. However, interferometers are not only expensive, but also introduce new errors after being removed from the self-collimating optical path because it is impossible to guarantee that the target generator or target is completely aligned with the interferometer light source. At the same time, when the aperture of the collimator to be aligned is large, the standard plane mirror also needs to be large. Large-aperture standard plane mirrors are not optical tube components, and their production costs are high and difficult. If they have large surface shape errors, they will directly affect the position of the reflected image and cause calibration errors.

[0004] Therefore, researching a collimator assembly and adjustment device that is widely applicable, highly accurate, and inexpensive will provide strong technical support for the development of optical measurement, scientific research and experimentation and other fields. Utility Model Content

[0005] The purpose of this application is to provide a collimator assembly and adjustment device and system, which has a simple structure and is easy to manufacture. It can be used for assembly and adjustment scenarios of collimators of various diameters and reflective types. While ensuring the applicability and accuracy of assembly and adjustment, it helps enterprises / related departments to reduce costs and increase efficiency.

[0006] The technical solution provided in this application is as follows:

[0007] On the one hand, this application provides a collimator assembly and adjustment device, comprising:

[0008] The stage is detachably mounted on one side of the horizontal direction of the collimator to be installed and adjusted;

[0009] A calibration light source is set on the platform and aligned with the light emission end of the collimator to be installed. It is used to provide a horizontal calibration parallel light so that the calibration parallel light is converged by the off-axis parabolic mirror of the collimator to be installed and reflected by the plane mirror before converging onto the target of the target generator and forming a first light spot to assist in adjusting the height of the mounting reference axis of the collimator to be installed.

[0010] The optical path deflection module is horizontally and reciprocally slidable on the platform along the sagittal direction of the collimator to be installed and is located between the calibration light source and the collimator to be installed. It is used to ensure that the outgoing light from the collimator to be installed does not diverge or converge in the sagittal direction, but only deflects at a preset angle.

[0011] A dynamic image quality analyzer, mounted on the platform, includes a detector aligned with the light-emitting end of the optical path deflection module. The detector receives the emitted light from the collimator to be adjusted after it has been deflected by the optical path deflection module and forms a second light spot on its detection surface. It also includes a calculation module. The detector is communicatively connected to the calculation module to record the position data of the second light spot during the movement of the optical path deflection module and feed it back to the calculation module. The calculation module then calculates the change in the position of the second light spot based on the position data, thereby assisting in adjusting the collimation accuracy of the collimator.

[0012] This application provides a collimator assembly and adjustment device, which combines a calibration light source, an optical path reversing module, and a dynamic image quality analyzer to form an assembly and adjustment device for collimators. This replaces the method of using a standard plane mirror and interferometer combination to assemble and adjust collimators in related technologies. Since there are corresponding products with quality standards on the market for the calibration light source, optical path reversing module, and dynamic image quality analyzer, this collimator assembly and adjustment device is easy to assemble, suitable for industrial production, and inexpensive. At the same time, by setting the optical path reversing module to have a matching travel according to the aperture of the collimator to be assembled and adjusted, the assembly and adjustment requirements of various reflective collimators with different apertures can be met, which expands the applicability of the collimator assembly and adjustment device and further reduces its production cost. Moreover, since there are almost no sources of error in the assembly and adjustment process, the assembly and adjustment accuracy is high and the reliability is strong, resulting in good overall performance and helping enterprises / related departments to reduce costs and increase efficiency.

[0013] In some embodiments, the optical path deflection module includes a pentaprism;

[0014] The exit surface of the pentaprism is perpendicular to the exit surface of the collimator to be installed.

[0015] In some embodiments, a driving element is also included, which drives the pentaprism to slide horizontally back and forth along the sagittal direction of the collimator to be installed.

[0016] In some embodiments, the driving element includes a linear guide and a drive motor;

[0017] The linear guide rail is horizontally arranged and parallel to the arc direction of the parallel light tube to be installed and adjusted; the drive motor is located at one end of the linear guide rail, its output shaft is parallel to the linear guide rail, and the end of its output shaft is fixedly connected to the slider of the linear guide rail.

[0018] The pentaprism is mounted on the slider of the linear guide rail;

[0019] Alternatively, the driving component includes a manual translation stage with a preset stroke, wherein the guide rail of the manual translation stage is horizontally arranged and parallel to the arc direction of the collimator to be installed;

[0020] The pentaprism is mounted on the slider of the manual translation stage.

[0021] This application provides a collimator assembly and adjustment device that uses a pentaprism, a linear guide rail, and a drive motor to form a light path reversal module, or a pentaprism and a manual translation stage to form a light path reversal module. Because the pentaprism can deflect light by 90° while maintaining the original image, it does not generate inverted or reversed images. Furthermore, the pitch, yaw, and movement speed during its sliding process do not affect the assembly and adjustment results in the sagittal direction of the collimator, effectively reducing the precision requirements for the production and assembly of the light path reversal module. Moreover, a standard pentaprism with a suitable aperture can be selected based on the aperture of the collimator to be assembled and adjusted. The light path reversal module has a simple structure and is easy to produce. Therefore, it helps to further promote cost reduction and efficiency improvement for enterprises and related departments.

[0022] In some embodiments, the pentaprism is detachably connected to the slider via a connector.

[0023] This application provides a collimator assembly and adjustment device, which is equipped with a pentaprism and a slider of a linear guide rail or a slider of a manual translation stage that can be detachably connected, making it convenient for workers to assemble and replace the pentaprism, thereby improving the ease of production and use of the collimator assembly and adjustment device.

[0024] In some embodiments, the stage includes an optical breadboard.

[0025] This application provides a collimator assembly and adjustment device, which uses an optical breadboard as a platform to facilitate the assembly and disassembly of the collimator assembly and adjustment device for adjusting collimators on different optical platforms, thereby expanding the applicability of the collimator assembly and adjustment device and improving its practicality. Furthermore, by using the optical breadboard as a support, interference such as vibration, deformation, and temperature drift during the collimator assembly and adjustment process can be eliminated, providing a stable reference environment for the collimator assembly and adjustment operation and helping to ensure the assembly and adjustment accuracy.

[0026] In some embodiments, the calibration light source, the optical path deflection module, and the dynamic image quality analyzer are all detachably connected to the stage.

[0027] This application provides a collimator assembly and adjustment device, in which the calibration light source, optical path deflection module, and dynamic image quality analyzer can all be detachably installed on the stage. This improves the ease of production and assembly of the collimator assembly and adjustment device, while also facilitating the replacement of corresponding assembly and adjustment auxiliary equipment such as the calibration light source for maintenance of the collimator assembly and adjustment device, or for modification of the collimator assembly and adjustment device to be applicable to assembly and adjustment scenarios of other optical components, thus helping to further expand its applicable scenarios.

[0028] In some embodiments, the calibration light source includes a laser theodolite.

[0029] In some embodiments, the dynamic image quality analyzer includes a focusable image analyzer.

[0030] On the other hand, this application also provides a collimator assembly and adjustment system, which includes any of the collimator assembly and adjustment devices described above; and further includes:

[0031] Optical platform;

[0032] The stage is detachably mounted on the optical platform;

[0033] The collimator to be installed is detachably mounted on the optical platform and located on one side of the stage in the horizontal direction; it includes an independently set target generator, a plane mirror and an off-axis parabolic mirror, all three of which are adjustable relative to the optical platform.

[0034] Compared with the prior art, the collimator assembly and adjustment device and system provided in this application have at least one of the following advantages:

[0035] 1. This application adopts a simple and low-cost solution, forming a collimator assembly and adjustment device by combining a pentaprism (and its sliding drive component), a dynamic image quality analyzer, and a laser theodolite. On the one hand, all components of this collimator assembly and adjustment device have corresponding standard products on the market, the production materials are readily available, and assembly is convenient, which is conducive to industrialization, mass production, and rapid production at low cost. At the same time, in the specific collimator assembly and adjustment operation, it can not only ensure the aberration of the collimator, but also ensure the accuracy and reliability of the collimator assembly and adjustment results due to the fixed assembly and adjustment position of the target generator. Moreover, by adjusting the reciprocating sliding stroke of the pentaprism, it can be adapted to the assembly and adjustment scenarios of collimators of different diameters and reflective types. Thus, while ensuring the applicability of the collimator assembly and adjustment device and improving its assembly and adjustment accuracy, it effectively promotes energy conservation and cost reduction for enterprises / related departments.

[0043] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0044] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0045] In the field of optical testing and calibration, collimators are crucial tools for assembling and adjusting optical instruments, and their calibration accuracy directly affects the testing accuracy of optical systems. Currently, related technologies primarily employ the autocollimation method for collimator calibration, for example, using a reference... Figure 1 The interferometer 100 is equivalent to a self-collimating eyepiece, and the high-precision collimator is assembled and adjusted. Specifically, the light emitted by the interferometer 100 with a certain divergence angle is reflected by the plane mirror 200 to the off-axis parabolic mirror 300. After being collimated by the off-axis parabolic mirror 300, it is reflected back to the off-axis parabolic mirror 300 by the standard plane mirror 400. Finally, it is converged by the plane mirror 200 to the interferometer 100, forming a self-collimating interference light path. By adjusting the scale on the reticle and the focusing of the reflected image, self-collimation is achieved, thereby completing the correction.

[0046] However, regarding the aforementioned technologies, interferometers are not only expensive, but also introduce new errors because removing them from the self-collimating optical path cannot guarantee that the target generator or reticle will perfectly coincide with the interferometer's light source position. This results in high relative positioning accuracy between the plane mirror and the off-axis parabolic mirror after calibration, but the target position of the off-axis parabolic mirror's focal point cannot be guaranteed. Furthermore, when the collimator to be calibrated has a large aperture, the standard plane mirror also needs a large aperture, which is difficult and costly to produce. If it has a large surface shape error, it will directly affect the position of the reflected image, further causing calibration errors. Therefore, the aforementioned collimator calibration method has limited applicability, low accuracy in calibrating the target generator or reticle, and high cost, and thus requires improvement.

[0047] In one embodiment, reference is made to the accompanying drawings. Figure 2 and Figure 3A collimator assembly and adjustment device is provided, comprising a stage 1, a calibration light source 2, an optical path deflection module 3, and a dynamic image quality analyzer 4 mounted thereon. In practical applications, the calibration light source 2 is aligned with the light emission end of the collimator to be assembled and adjusted, providing horizontal calibration parallel light rays. These parallel light rays are then converged sequentially by the off-axis parabolic mirror 300 of the collimator to be assembled and adjusted, reflected by the plane mirror 200, and finally converged onto the target of the target generator 500, forming a first light spot to assist in adjusting the height of the collimator's mounting reference axis. The optical path deflection module 3 is horizontally and reciprocally slidable on the stage 1 along the sagittal direction of the collimator to be assembled and adjusted, and is located between the calibration light source 2 and the collimator to be assembled and adjusted. Between the tubes, a mechanism is used to ensure that the outgoing light from the collimator to be installed does not diverge or converge in the sagittal direction, but only deflects at a preset angle; the dynamic image quality analyzer 4 includes a detector and a computing module, wherein the detector is positioned aligned with the light-emitting end of the optical path deflection module 3, and is used to receive the outgoing light from the collimator to be installed after it has been deflected by the optical path deflection module 3, and to form a second light spot on its detection surface; the detector is also communicatively connected to the computing module to record the position data of the second light spot during the movement of the optical path deflection module 3, and to feed it back to the computing module, so that the computing module can calculate the change data of the position of the second light spot based on the position data of the second light spot, thereby assisting in adjusting the collimation accuracy of the collimator to be installed.

[0048] As is well known, in the initial state, the collimator to be assembled is usually adjustablely positioned on the corresponding optical platform. For example, the components inside the collimator to be assembled are roughly positioned by fasteners, and then the fasteners are fixed on the corresponding optical platform. During the collimator assembly and adjustment, stage 1 is placed on the corresponding optical platform, and its setting angle is adjusted so that it is located on the side of the horizontal direction of the collimator to be assembled and adjusted. The calibration light source 2 is kept aligned with the light emission end of the collimator to be assembled and adjusted. Then, stage 1 is fixed on the optical platform. In specific calibration, first, the optical path deflection module 3 is moved out of the output optical path of the collimator to be assembled and adjusted. Then, the calibration light source 2 is turned on so that it emits horizontal (i.e., perpendicular to the zenith) calibration parallel light rays, which are incident on the collimator to be assembled and adjusted. The calibration parallel light rays are converged by the off-axis parabolic reflector 300 of the collimator to be assembled and adjusted, reflected by the plane reflector 200, and then converged on the target of the target generator 500 to form the first light spot. At this time, the height of the target generator 500 is adjusted so that the center of the target on it is at the same height as the first light spot, thus completing the "alignment of optical axis and mechanical axis" or "height coplanarity calibration" of the collimator to be assembled and adjusted. Then, the height of the target generator 500 is fixed and the calibration light source 2 is turned off.

[0049] Subsequently, the moving optical path deflection module 3 enters the output optical path of the collimator to be installed and adjusts, and controls the optical path deflection module 3 to slide back and forth within a part of its travel. The output light reflected by the off-axis parabolic reflector 300 of the collimator to be installed and adjusted is deflected by the optical path deflection module 3 at a preset angle and converges on the detection surface of the detector of the dynamic image quality analyzer 4, forming a second light spot. The calculation module of the dynamic image quality analyzer 4 obtains the change data of the position of the second light spot based on the position data information of the second light spot. The operator adjusts the sway of the plane reflector 200 and its distance from the target generator 500 along the optical axis according to the change data of the position of the second light spot until the change data of the position of the second light spot is 0, that is, the convergence position of the second light spot on the detection surface of the detector 4 no longer changes. The angle and position of the plane reflector 200 are fixed, thus completing the adjustment of the collimation accuracy of the corresponding collimator.

[0050] The collimator assembly and adjustment device of this application is suitable for industrialized mass production and is inexpensive because there are corresponding standard products for various auxiliary calibration equipment such as calibration light source and optical path conversion module on the market. At the same time, since the optical path conversion module 3 is horizontally slidable in the sagittal direction of the collimator to be assembled and adjusted, it can be applied to the assembly and adjustment requirements of various reflective collimators with different apertures. Moreover, the corresponding adjustment process can not only ensure the aberration of the collimator, but also determine the assembly and adjustment position of the target generator 500 in one go with almost no source of error and high assembly and adjustment accuracy. This makes it suitable for scenarios where the wavefront error PV value requirement is less than λ / 4. That is, the collimator assembly and adjustment device of this application is suitable for assembly and adjustment scenarios with higher accuracy requirements. It has a wide range of applications, strong practicality, and good comprehensive performance, which is beneficial to enterprises / related departments to reduce costs and increase efficiency.

[0051] In one embodiment, specifically based on the above embodiments. (Refer to...) Figure 2 and Figure 3 In this embodiment, the stage 1 is preferably configured as an optical breadboard to provide a stable reference environment, thereby ensuring assembly and adjustment accuracy.

[0052] Furthermore, in this embodiment, the calibration light source 2 is preferably set as a laser theodolite. During the collimator assembly and adjustment, when installing the optical breadboard, after keeping the laser emitting end of the laser theodolite facing the light emitting end of the collimator to be assembled and adjusted, the laser theodolite is adjusted until its level bubble is horizontal and its longitude direction is 90° and then fixed. Subsequently, the laser theodolite is turned on, and its emitted horizontal laser beam is used as the calibration parallel light. The calibration parallel light is converged by the off-axis parabolic reflector 300 of the collimator to be assembled and adjusted, reflected by the plane reflector 200, and then converged onto the target of the target generator 500, forming a first light spot. The height of the target generator 500 is adjusted according to the height of the first light spot until the center of the target on it is at the same height as the first light spot, thereby achieving the calibration of the coplanarity of the collimator height. In this way, by utilizing the advantages of the high parallelism of the laser beam emitted by the laser theodolite, the adjustable elevation direction to horizontal, and the visualization of the laser light spot, the reliability of the corresponding collimator assembly and adjustment results and the convenience of operation are effectively guaranteed.

[0053] In this embodiment, the optical path deflection module 3 is preferably configured as a pentaprism 31. The optical characteristics of the pentaprism 31 are used to achieve a stable 90° deflection of the light emitted from the collimator to be adjusted. Of course, the stage 1 is also equipped with a driving component 32 for driving the pentaprism 31 to slide horizontally back and forth along the sagittal direction of the collimator. In this embodiment, referring to… Figure 2 and Figure 3 The driving component 32 preferably includes a linear guide rail and a drive motor. Specifically, the linear guide rail is horizontally arranged parallel to the sagittal direction of the collimator to be installed and adjusted. The drive motor is installed at one end of the linear guide rail, and its output shaft is kept parallel to the linear guide rail. The pentaprism 31 is installed on the slider of the linear guide rail. The shaft end of the drive motor output shaft is fixedly connected to the slider of the linear guide rail, so as to push the corresponding slider and the pentaprism 31 on it to perform horizontal reciprocating sliding motion along the sagittal direction of the collimator in the start state. Since the optical characteristics of the pentaprism 31, such as light deflection characteristics, image retention characteristics, and high reflectivity, are not affected by vibration, the design and production stages of the collimator installation and adjustment device do not have excessive requirements for the pitch, yaw, and driving speed of the motor drive process.

[0054] In the embodiments of this application, the driving component 32 can also be configured as a manual translation stage with a long stroke, so that the collimator assembly and adjustment device can be used for the assembly and adjustment of ultra-large diameter reflective collimators, further expanding its applicable scenarios. Similarly, the guide rail of the manual translation stage also needs to be horizontally set on the stage 1 and parallel to the sagittal direction of the collimator to be assembled and adjusted; the pentaprism 31 is set on the slider of the manual translation stage.

[0055] In this embodiment, to improve production efficiency, the pentaprism 31 is preferably detachably connected to the corresponding slider via a connector, facilitating assembly and replacement of the pentaprism 31. It is worth noting that when installing the pentaprism 31, it is preferable to use flexible gaskets or elastic washers to hold the pentaprism 31 and to evenly tighten the connector to avoid deformation of the pentaprism 31 due to mechanical stress, which could affect the beam steering accuracy. Simultaneously, it must be ensured that the exit surface of the pentaprism 31 is perpendicular to the exit surface of the collimator to be installed and adjusted.

[0056] In this embodiment, depending on the diameter of the collimator to be installed, a standard pentaprism 31 with a suitable light transmission diameter can be selected. The corresponding optical path turning module has a wide range of applications and is easy to install.

[0057] Similarly, in the embodiments of this application, the calibration light source 2, the optical path deflection module 3, and the dynamic image quality analyzer 4 are preferably detachably connected to the stage 1; see reference Figure 2 and Figure 3 The laser theodolite, the pentaprism 31 drive unit 32, and the adjustable focus image analyzer 4 are all detachably connected to the optical breadboard to facilitate the production and maintenance of the collimator assembly device.

[0058] In this embodiment, the dynamic image quality analyzer 4 is preferably configured as an adjustable-focus image analyzer. Because it is equipped with automatic / electric focusing, it can automatically adjust the lens focal length according to different distances or target sizes, resulting in higher observation accuracy. Of course, in the embodiments of this application, the dynamic image quality analyzer 4 can also be configured as other similar auxiliary observation devices, and the specific configuration of the dynamic image quality analyzer 4 should not be construed as a limitation on the scope of protection of this application.

[0059] Of course, when the collimator assembly and adjustment device is applied to a specific collimator assembly and adjustment operation, in one embodiment, a collimator assembly and adjustment system may also be provided, as described above. Figure 3 The system includes the collimator adjustment device described in any of the above embodiments, and of course, also includes an optical platform and the collimator to be adjusted on it. The collimator to be adjusted is detachably mounted on the optical platform by fasteners. After the collimator adjustment device is also installed on the corresponding optical platform, the laser emitting end of the laser theodolite on it is aligned with the light emitting end of the collimator to be adjusted, and the pentaprism is kept horizontally sliding back and forth along the sagittal direction of the collimator to be adjusted between the laser theodolite and the collimator to be adjusted. In this embodiment, the collimator to be adjusted specifically includes an independently set target generator 500, a plane mirror 200, and an off-axis parabolic mirror 300. All three are adjustable relative to the optical platform by fasteners, so that their positions and angles can be adjusted to a standard state according to the verification results.

[0060] The implementation principle of this application embodiment is as follows: In the collimator assembly and adjustment operation, initially, the stage 1 is fixed on the optical platform on one side of the horizontal direction of the collimator to be assembled and adjusted, and the laser emitting end of the laser theodolite is kept aligned with the light emitting end of the off-axis parabolic reflector 300. During the adjustment operation, firstly, the pentaprism 31 is moved out of the output light path of the collimator to be assembled and adjusted, then the laser theodolite is leveled and turned on. The laser theodolite emits a horizontal (i.e., perpendicular to the zenith) laser beam as a calibration parallel light. The calibration parallel light is incident on the collimator to be assembled and adjusted, and is converged by the off-axis parabolic reflector 300 and reflected by the plane reflector 200 in sequence, and then converged on the target of the target generator 500 to form the first light spot. At this time, the height of the target generator 500 is adjusted so that the center of the target on it is at the same height as the first light spot. Then the height of the target generator 500 is fixed and the calibration light source 2 is turned off, so that the "optical axis-mechanical axis equal height alignment" or "height coplanarity calibration" operation of the collimator can be completed.

[0061] Subsequently, the pentaprism 31 is moved into the output light path of the collimator to be installed and adjusted, and the pentaprism 31 is controlled to slide horizontally back and forth within the light transmission aperture range of the off-axis parabolic reflector 300. The output light reflected by the off-axis parabolic reflector 300 is deflected by 90° by the pentaprism 31 and converges on the detection surface of the detector of the adjustable focus image analyzer, forming a second light spot. During the horizontal back and forth sliding motion of the pentaprism 31, the detector of the adjustable focus image analyzer records the position data of the second light spot and feeds it back to the calculation module. The calculation module obtains the change data of the position of the second light spot based on the corresponding position data information. According to the corresponding change data of the position of the second light spot, the operator adjusts the sway of the plane reflector 200 and its distance from the target generator 500 along the optical axis until the corresponding change data of the position of the second light spot is 0, that is, the convergence position of the second light spot on the detection surface of the corresponding detector no longer changes. The angle and position of the plane reflector 200 are fixed, thus completing the adjustment of the collimation accuracy of the collimator.

[0062] The collimator assembly and adjustment device, formed by combining a laser theodolite, a pentaprism 31, and an adjustable focus image analyzer, is not only simple in structure and easy to assemble, making it suitable for industrial production, but also applicable to various customized collimator assembly and adjustment scenarios. All components within the collimator to be assembled and adjusted can be completed in one go, effectively ensuring the efficiency and accuracy of the corresponding assembly and adjustment process. Thus, while minimizing production costs, it effectively improves the applicability and accuracy of the collimator assembly and adjustment device, thereby promoting cost reduction and efficiency improvement for enterprises and related departments.

[0063] It should be noted that the above embodiments can be freely combined as needed. The above description is only a preferred embodiment of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the protection scope of this application.
