Description

Technical Field

[0001] The utility model relates to the technical field of aerospace, in particular to a parts assembly auxiliary device. Background Art

[0002] Sun sensors are the most widely used type of sensor in the aerospace field and are installed on all satellites. By sensing the position of the solar vector, the position of the solar vector in stellar coordinates is determined, thereby obtaining information about the spacecraft's position relative to the sun. During the assembly of a sun sensor, ensuring that the center of the solar cell on the printed circuit board is aligned with the center of the through-hole in the casing is crucial. This is because the performance and accuracy of a sun sensor are directly related to the angle at which sunlight is received. Any misalignment between the center of the solar cell and the sun sensor can cause errors when sunlight enters the sensor, affecting measurement accuracy and precision.

[0003] During the assembly of the sun sensor, the center of the solar cell panel and the center of the sun sensor's light hole must be kept consistent. However, in the actual assembly process, alignment can only be performed by the naked eye. Alignment with the naked eye will produce large deviations, and center offset and misalignment are likely to occur. Once a large offset occurs, it will seriously affect the overall performance (accuracy) of the sun sensor.

[0004] Therefore, there is an urgent need for a sun sensor assembly auxiliary device that can simplify the assembly process, improve assembly efficiency, and ensure assembly accuracy. Utility Model Content

[0040] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0041] like Figure 1 As shown, a solar sensor 1 is the most widely used sensor in the aerospace field and is installed on all satellites. The solar sensor 1 comprises a solar sensor housing 11, a printed circuit board 12, and solar cells 13. The solar cells 13 are mounted on the printed circuit board 12, which is housed within the solar sensor housing 11. A light hole is provided in the solar sensor housing 11, exposing the solar cells 13 to receive light and convert it into electrical energy.

[0042] A first crosshair 131 is provided on the solar cell panel 13. During assembly of the solar sensor 1, it is crucial to align the center of the solar cell panel 13, i.e., the center of the first crosshair 131, with the center of the light aperture of the solar sensor housing 11. During actual assembly, alignment can only be performed visually, which can lead to significant deviations, easily causing center offset or misalignment. Significant offset can seriously affect the overall performance (accuracy) of the solar sensor 1.

[0043] In order to solve the problem that the alignment will produce large deviations when observed with the naked eye, such as Figure 2-Figure 4As shown, this embodiment provides a parts assembly auxiliary device to assist in aligning the center of the solar cell sheet 13 in the printed circuit board 12 with the center of the light hole of the solar cell housing 11. The parts assembly auxiliary device includes a mounting frame 2 and an electron microscope 3. The mounting frame 2 includes a first bracket 21 and a second bracket 22. The first bracket 21 is used to support the solar sensor 1. The first bracket 21 opens a through hole facing the solar sensor housing 11. Auxiliary markings 2122 are set around the through hole on the side of the first bracket 21 facing the second bracket 22, including a first marking 21221 and a second marking 21222 that are perpendicular to each other. The intersection of the extension lines of the first marking 21221 and the second marking 21222 coincides with the theoretical center; the electron microscope 3 is set on the second bracket 22, and the lens of the electron microscope 3 faces the first bracket 21, so that the electron microscope 3 can observe the image on the first bracket 21. The operator can move the solar cell 13 so that the center of the first cross mark 131 coincides with the center of the auxiliary marking 2122, so as to achieve the goal of making the center of the solar cell 13 consistent with the center of the through hole of the solar sensor housing 11, thereby making the measurement accuracy and precision of the solar sensor 1 higher.

[0044] Exemplarily, the theoretical center is the center of the through hole, and the center of the through hole coincides with the center of the light-through hole of the Taimin housing 11 .

[0045] Due to the setting of the through hole, the first mark 21221 and the second mark 21222 in the auxiliary mark 2122 are located outside the through hole, that is, there is a certain distance from the first cross mark on the solar cell panel 13 in the through hole. Errors are likely to occur during the adjustment process. For this reason, in some embodiments, a second cross mark is provided in the electron microscope 3. By adjusting the position of the second cross mark in the electron microscope 3, the center of the second cross mark is first made to coincide with the center 2122 of the auxiliary mark. At this time, the center of the solar sensor housing 11 coincides with the second cross mark. Then, the position of the solar cell panel 13 is moved to move the first cross mark 131 to coincide with the second cross mark. Since the second cross mark coincides with the auxiliary mark 2122, the first cross mark 131 coincides with the auxiliary mark 2122, and then the first cross mark 131 coincides with the center of the solar sensor housing 11, thereby improving the measurement accuracy and precision of the solar sensor 1.

[0046] Specifically, if Figure 2-Figure 4 As shown, in this embodiment, a first mounting groove 2121 is provided on the first bracket 21. The inner circumference of the first mounting groove 2121 is the same as the outer circumference of the Taimin housing 11. Due to the above configuration, the inner circumference of the Taimin housing 11 and the outer circumference of the first mounting groove 2121 are the same, thereby preventing the Taimin housing 11 from moving relative to the horizontal direction, so that the Taimin housing 11 is fixed in the first mounting groove 2121. In addition, the center of the Taimin housing 11 does not change randomly, which would affect the installation accuracy of the solar panel.

[0047] Specifically, if Figures 1-4 As shown, in this embodiment, the first bracket 21 includes a bracket body 211 and an adapter plate 212. The adapter plate 212 is detachably mounted on the bracket body 211, and a first mounting slot 2121 is provided on the adapter plate 212. If the specifications of the solar sensor 1 to be assembled change, the adapter plate 212 can be replaced according to the specifications of the solar sensor 1 without replacing the entire mounting bracket 2. The through-holes include a first through-hole provided on the bracket body 211 and a second through-hole provided at the bottom surface of the first mounting slot 2121. The second through-hole is aligned with the first through-hole, ensuring that the centers of the adapter plate 212 and the bracket body 211 are aligned. This allows the center of the solar cell housing 11 placed thereon to coincide with the center of the bracket body 211. This facilitates alignment of the first crosshair 131 and the auxiliary reticle 2122, ensuring that the center of the solar cell panel 13 coincides with the center of the light aperture of the solar cell housing 11, without any deviation.

[0048] In some embodiments, the size of the second through hole may be smaller than the size of the bottom surface of the first mounting groove 2121 , and the bottom surface of the first mounting groove 2121 can support the Taimin housing 11 .

[0049] In other embodiments, the size of the second through hole is the same as the size of the bottom surface of the first mounting groove 2121, that is, the second through hole is used to realize the function of the first mounting groove 2121. The Taimin housing 11 includes a shell body and a flange. The flange is arranged along the circumference of the shell body and is connected to the shell body. The flange and the adapter plate 212 abut to fix the Taimin housing 11, thereby preventing the Taimin housing 11 from falling off from the first through hole and causing damage to other components.

[0050] Specifically, if Figures 1-4 As shown, in this embodiment, a second mounting groove 2111 is provided on the bracket body 211, and a first through hole is provided on the bottom surface of the second mounting groove 2111. The inner circumference size of the second mounting groove 2111 is the same as the outer circumference size of the adapter plate 212, so that the adapter plate 212 will not move relative to each other in the horizontal direction, and thus the Taimin housing 11 will not move relative to each other in the horizontal direction, so that the adapter plate 212 is fixed in the second mounting groove 2111, and thus the center of the center box adapter plate 212 of the Taimin housing 11 will not change irregularly, affecting the installation accuracy of the solar panel.

[0051] Optionally, in this embodiment, if Figures 1-4As shown, auxiliary markings 2122 are provided on the adapter plate 212 and face the first through-hole, allowing the electron microscope 3 to observe the auxiliary markings 2122 through the first through-hole. The auxiliary markings 2122 on the adapter plate 212 are then used to adjust the position of the solar panel so that the first cross markings 131 and the auxiliary markings 2122 coincide with each other, thereby improving the installation accuracy of the solar panel and avoiding the problem of poor measurement accuracy of the solar sensor 1 due to low installation accuracy of the solar panel. In other embodiments, the auxiliary markings 2122 can be provided on the bracket body 211, so that the first cross markings 131 and the auxiliary markings 2122 can coincide with each other through observation by the electron microscope 3 and the moving portion of the solar panel, thereby improving the installation accuracy of the solar panel.

[0052] Specifically, if Figure 2-Figure 4 As shown, in this embodiment, the second bracket 22 is provided with a first mounting hole, the electron microscope 3 is arranged in the first mounting hole, and the second bracket 22 is provided with a first fastener 221, which is used to fix the electron microscope 3 so that the position of the electron microscope 3 in all directions does not change. When the electron microscope is used to observe the first bracket 21 and the sun sensor 1 and adjust the solar panel, the electron microscope 3 will not be displaced due to not being fixed properly, thereby causing a deviation in the overlap of the first cross mark 131 and the auxiliary mark 2122, and thus making it impossible for the center of the first cross mark 131 on the solar panel to coincide with the center of the solar sensor housing 11, thereby affecting the installation accuracy of the solar panel and the measurement accuracy and precision of the sun sensor 1.

[0053] Optionally, the first fastener 221 may be a pin or a screw, etc. The first fastener 221 extends into the first mounting hole and abuts against the electron microscope 3, thereby fixing the electron microscope 3 in the first mounting hole.

[0054] Optionally, in this embodiment, the through hole is opposite to the first mounting hole. In other words, the through hole is coaxial with the first mounting hole, so that the electron microscope 3 can be opposite to the through hole after being installed in the first mounting hole. It is more convenient to adjust the electron microscope 3 so that the second cross mark is opposite to the auxiliary mark 2122. There is no need to adjust the general position of the electron microscope 3, and only minor adjustments are required.

[0055] Specifically, if Figures 1-4As shown, in this embodiment, the parts assembly auxiliary device further includes a bearing assembly 4, which includes a bearing plate 41 and a mounting member 42. The mounting member 42 is vertically fixed to the bearing plate 41, and the mounting frame 2 is connected to the mounting member 42 and is height-adjustable. The bearing assembly 4 can provide support for the mounting frame 2, enabling the mounting frame 2 to function properly. Since the mounting frame 2 is connected to the supporting assembly, the mounting frame 2 has support force, which in turn provides support force for both the first bracket 21 and the second bracket 22. This allows the first bracket 21 to support the parts that make up the sun sensor 1, preventing the mounting frame 2 from having insufficient support force or an unstable center of gravity, thereby preventing the parts that make up the sun sensor 1 carried on the first mounting frame 2 from scattering and affecting the assembly of the sun sensor 1.

[0056] Specifically, if Figure 2-Figure 4 As shown, in this embodiment, the mounting frame 2 further includes a connecting member 23, one end of the connecting member 23 is connected to the first bracket 21, and the other end of the connecting member 23 is connected to the second bracket 22. The connecting member 23 is sleeved on the outside of the mounting member 42, so that the movement of the first bracket 21 and the second bracket 22 are synchronized, so as to avoid errors in the imaging of the electron microscope 3 due to asynchronous movement, thereby avoiding deviations in the assembly of the sun sensor 1.

[0057] Specifically, if Figure 2-Figure 4 As shown, in this embodiment, the mounting frame 2 is slidably connected to the mounting member 42 and further includes a first locking assembly 24 that can selectively secure the mounting frame 2 at at least two height positions of the mounting member 42. This arrangement allows the mounting frame 2 to slide on the mounting member 42 to adjust the optimal field of view of the electron microscope 3. Furthermore, when the sun sensor 1 and the electron microscope 3 are mounted on the mounting frame 2, the mounting frame 2 can be adjusted to a suitable height for installation, facilitating the installation of the sun sensor 1 and the electron microscope 3. This merely improves the assembly efficiency of the auxiliary parts assembly device.

[0058] Alternatively, as Figure 2-Figure 4 As shown, in this embodiment, the mounting member 42 is a relatively smooth rod-shaped structure, and the first locking component 24 is a knob that is threadedly connected to the mounting frame 2. One end of the knob extends into the mounting frame 2 and can abut against the mounting member 42. When the knob is rotated to abut against the mounting member 42, the mounting frame 2 can be fixed to the mounting member 42; when the knob is rotated away from the mounting member 42, the height of the mounting frame 2 can be adjusted.

[0059] In other embodiments, the mounting member 42 may be a rod-shaped structure with multiple recesses, and the first locking component 24 may be a screw. When the position of the mounting frame 2 is to be changed, the screw is unscrewed. Once the position is determined, the screw is screwed in again and abuts against any of the multiple recesses to secure the mounting frame 2. As long as the mounting frame 2 can slide on the mounting member 42 and be secured to the mounting member 42, any suitable arrangement will suffice.

[0060] In other embodiments, the mounting frame 2 may be provided with at least one hole arranged in a vertical direction, and the mounting member 42 may be provided with at least one hole arranged in a vertical direction. The parts assembly auxiliary device further includes a stopper, which can be passed through any hole in the mounting frame 2 and any hole in the mounting member 42 to position the mounting frame 2. When the relative position of the mounting frame 2 on the mounting member 42 needs to be adjusted, the stopper can be removed from the mounting frame 2 and the mounting member 42. Optionally, the stopper can be provided with one, two, or three, etc., as long as the mounting frame 2 can be fixed to the mounting member 42.

[0061] Optionally, the limiting member may be a pin or a screw, etc., as long as it can limit the mounting bracket 2 so that the mounting bracket 2 can be fixed on the mounting member 42 .

[0062] In other embodiments, taking a pin as an example, the mounting member 42 has a plurality of holes arranged in a vertical direction, the pin is passed through one of the holes, and both ends extend out of the mounting member 42, and the bottom end of the mounting frame 2 is placed on the pin to fix the position of the mounting frame 2.

[0063] Specifically, if Figures 1-4 As shown, in this embodiment, the parts assembly auxiliary device also includes a camera 5 and a display 6. The camera 5 is arranged at the eyepiece end of the electron microscope 3. The camera 5 is electrically connected to the display 6. The camera 5 can obtain image information of the first bracket 21 and transmit the image information of the first bracket 21 to the display 6 through an electrical signal, so that the operator can more intuitively see the alignment of the solar panel and the solar cell housing 11, and can also more intuitively see the alignment of the first cross mark 131 and the auxiliary mark 2122, so as to facilitate the adjustment of the position of the solar panel.

[0064] Optionally, the camera 5 can be a SLR camera or a CCD camera. In this embodiment, in order to avoid functional redundancy or insufficient function, a CCD camera is selected to transmit the image information of the electron microscope 3. The CCD camera can receive and transmit all the information that the electron microscope 3 wants to convey to the display 6, without insufficient function or redundancy, and the CCD camera has a relatively high cost performance.

[0065] It should be noted here that the display 6 is an existing structure, and setting a display 6 in a parts assembly auxiliary device is a conventional setting in this field. In this embodiment, any display 6 in the existing technology can be used, and any connection method in the existing technology can be used to electrically connect it to the CCD camera. As long as the image captured by the CCD camera can be displayed, no further detailed introduction will be given.

[0066] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
