[0025] See also Figures 1 to 3The first embodiment of the present application provides a combiner debugging system, which is used to adjust the extension length of multiple tuning screws 4 arranged on the combiner cover plate 2. The combiner debugging system may include: a fixture substrate 1, multiple limit screws 7, multiple pressure sensors 8 and a processing device 10, wherein the fixture substrate 1 has a fixture cavity, a pressure sensor matching portion is formed at the bottom of the fixture cavity, and a plurality of through holes are opened on the pressure sensor matching portion, and the number of the through holes is the same as the number of the tuning screws 4; the multiple limit screws 7 correspond to the multiple tuning screws 4 one by one and are inserted into the corresponding through holes, and each limit screw 7 is hollow and the opening faces the tuning screw 4; A plurality of pressure sensors 8 are arranged one by one in the limit screw 7. The pressure sensor 8 has a main body and a pressure probe that are connected to each other. The main body abuts against the sealed end of the limit screw 7, and the pressure probe is exposed from the open end of the limit screw 7. A processing device 10 is electrically connected to each pressure sensor 8. The processing device 10 is connected to a display device 9. The processing device 10 is used to determine a target pressure range of each tuning screw 4 according to a preset corresponding relationship and a target depth of each tuning screw 4, and control each tuning screw 4 to have a target depth in the fixture cavity according to a comparison result of the pressure value output by the pressure sensor 8 and the target pressure range, and display the pressure value of the pressure sensor 8 through the display device 9.

[0026] In this embodiment, when the tuning screw 4 on the combiner cover plate 2 needs to be adjusted, the combiner cover plate 2 is first placed on the combiner cover plate mating portion of the jig substrate 1. Then, each tuning screw 4 is roughly adjusted so that the tuning screw 4 contacts the pressure sensor 8, and then the pressure value output by the pressure sensor 8 is compared with the target pressure range corresponding to the target depth of the tuning screw 4, and each tuning screw 4 is fine-tuned until the pressure value of the pressure sensor 8 matches the target pressure range, indicating that the tuning screw 4 has the target depth, and the adjustment of the tuning screw 4 is completed. In this process, the debugging personnel can observe the pressure readings displayed on the display device 9 until all tuning screws 4 reach the ideal set value. When debugging the combiner provided by the present application, the debugging personnel can observe the pressure value of each tuning screw 4 in real time, so as to judge whether the extended length of the tuning screw 4 is appropriate. The debugging process is simple, and debugging no longer relies on manual experience and operation. Different debugging personnel obtain the same results, thereby ensuring the stability of product quality. In addition, debugging the combiner through the combiner debugging system provided by the present application can meet the needs of large-scale production.

[0027] The specific structure and working principle of the combiner debugging system provided by the present application are introduced in detail below with reference to the accompanying drawings.

[0028] In this exemplary embodiment, the jig substrate 1 can be set according to the structure of the combiner cavity to be debugged. Specifically, the pressure sensor 8 is set on the jig substrate 1 according to the position of the tuning screw 4 on the combiner cavity, so that the jig substrate 1 can adjust the depth of the tuning screw 4 on the combiner cover 2 of this model. The depth of the jig cavity of the jig substrate 1 is greater than the depth of the combiner cavity to be debugged, so as to leave a length of the limit screw 7 so that the tuning screw 4 can squeeze the corresponding pressure sensor 8 to generate a pressure signal.

[0029] In this exemplary embodiment, a jig substrate 1 that matches the combiner cover plate 2 can be produced based on the simulation results. The design of the jig substrate 1 should accurately match the size of the combiner cover plate 2 and the installation position of the tuning screw 4 to ensure that the tuning screw 4 can be assembled in place at one time. High-precision processing technologies such as CNC machining can be used to produce the jig substrate 1 to ensure dimensional accuracy at the micron level. For example, the length deviation of the jig substrate 1 can be controlled within ±0.01 mm, the width deviation can be controlled within ±0.01 mm, and the height deviation can be controlled within ±0.02 mm. The surface roughness of the jig substrate 1 can be controlled below 0.05 microns to ensure the stability and accuracy of the installation of the tuning screw 4.

[0030] In this exemplary embodiment, the fixture substrate 1 can be an integrally formed structure. It can be understood that the integrally formed fixture substrate 1 has better stability and reliability. Here, the fixture substrate 1 is set as an integrally formed structure, which can ensure the adjustment accuracy of the tuning screw 4 and can be manufactured by die casting.

[0031] The limit screw 7 is a hollow structure with an open opening, and the pressure sensor 8 is placed in the cavity of the limit screw 7. The limit screw 7 can protect the pressure sensor 8 located therein. Specifically, the body of the pressure sensor 8 and the inner wall of the limit screw 7 are interference fit, and there is a gap between the pressure probe and the inner wall of the limit screw 7. In this way, when the tuning screw 4 squeezes the pressure probe, the limit screw 7 can be used to limit the circumference of the pressure probe to avoid the shaking of the pressure probe and affect the pressure detection accuracy.

[0032] Furthermore, in some embodiments, the limit screw 7 can be engaged in the corresponding through hole by means of a threaded connection, so that the depth of the tuning screw 4 in the jig cavity can be changed by rotating the limit screw 7. Since the position of the pressure sensor 8 in the limit screw 7 is fixed, the height of the pressure probe of the pressure sensor 8 in the jig cavity can be indirectly adjusted by adjusting the depth of the limit screw 7 in the jig cavity, that is, the distance between the pressure probe and the combiner cover plate 2 engaged on the jig substrate 1 is adjusted. In this way, the jig substrate 1 provided in the present application can be adapted to combiners of the same model but with different parameter requirements.

[0033] For example, the jig substrate 1 is adapted to a combiner of model A, that is, the position and number of the pressure sensors 8 it has correspond one-to-one to the position and number of the tuning screws 4 on the combiner cover plate 2 of model A. Assuming that the target depth of tuning screw No. 1 4 of the combiner of model A in the first usage scenario is 3 cm, and the target depth of tuning screw No. 1 4 in the second usage scenario is 5 cm, then for the first usage scenario, the height of the limit screw 7 corresponding to tuning screw No. 1 4 in the jig cavity can be adjusted to h1, so that the tuning screw 4 can contact the pressure probe when it is close to the depth of 3 cm, and then the depth of the tuning screw 4 is fine-tuned based on the pressure value output by the pressure sensor 8 until the pressure value meets the target pressure value corresponding to the target depth of 3 cm; and in the second usage scenario, the depth of the limit screw 7 corresponding to tuning screw No. 1 4 in the jig cavity can be adjusted to h2, h2

[0034] It can be seen that the provided limiting screw 7 improves the applicability of the fixture substrate 1 .

[0035] In this exemplary embodiment, the processing device 10 has a certain data processing capability so as to be able to convert the target depth of the tuning screw 4 into a corresponding pressure range according to a preset mapping relationship. Specifically, on the one hand, it converts the target depth of each tuning screw 4 into a corresponding target pressure range through a built-in preset mapping relationship, and then determines whether the current pressure value acquired in real time reaches the target pressure range of the tuning screw 4 at the corresponding position. When the real-time detected pressure value enters the target pressure range, it indicates that the depth of the tuning screw 4 has reached the target depth; on the other hand, the processing device 10 is connected to a display device 9, which can display the real-time detected pressure value through the connected display device 9, so that it is convenient for the debugging personnel to view.

[0036] It should be understood that the processing device 10 in the embodiment of the present application can be implemented in a variety of specific forms, such as an integrated tablet, or a computer connected to a display, etc.

[0037] In this exemplary embodiment, when assembling the tuning screw 4 in the fixture cavity, automated equipment can be used to improve assembly efficiency and accuracy. For example, automated tightening equipment is used to ensure that the tightening torque of the tuning screw 4 is consistent and the deviation is less than 0.5 Newton meters. The matching clearance between the tuning screw 4 and the fixture cavity is controlled within 0.02 mm to ensure the position accuracy of the tuning screw 4 in the fixture cavity.

[0038] ​In addition, it should be understood that the target depth of each tuning screw 4 can be obtained through electromagnetic simulation. For example, professional electromagnetic simulation software can be used to input the working parameters, material properties and other information of the combiner to be debugged, and the working state of the combiner can be simulated, so that the electromagnetic simulation software can calculate the optimal depth, i.e., the target depth, of each tuning screw 4. The specific method for simulating the target depth of each tuning screw 4 can be referred to the prior art, and is not specifically limited here.

[0039] It is worth noting that in the embodiment of the present application, because the target depths of the tuning screws 4 are different, before the combiner cover plate 2 is assembled on the jig substrate 1, it is necessary to first adjust the height of the limit screw 7 in the jig cavity according to the target depth of each tuning screw 4, so that the limit screw 7 is close to the tuning screw 4 at the corresponding position, so that the tuning screw 4 can contact the corresponding pressure sensor 8 during the adjustment process and generate a pressure signal.

[0040] Furthermore, in the exemplary embodiment, the processing device 10 and the plurality of pressure sensors 8 are connected via cables or wirelessly.

[0041] Specifically, when the processing device 10 is connected to the multiple pressure sensors 8 by cables, the connection is usually relatively stable and not susceptible to external interference, and is suitable for use in environments that require high reliability; direct data transmission through cables has low latency and good real-time performance, and is relatively simple to install and configure, and does not require additional wireless devices. When the processing device 10 is connected to the multiple pressure sensors 8 by wireless, it is more flexible, no wiring is required, and the fixture substrate 1 or the processing device 10 can be moved freely; there are no complicated cables through wireless connection, and the working area is tidier. In summary, the choice of wired or wireless connection depends on the specific application requirements. If the application scenario is fixed and the speed and stability of data transmission are very high, then wired connection is a better choice. If mobility and flexibility are required, or if you work in an environment where wiring is not convenient, then wireless connection is more suitable. Regardless of the connection method used, it is necessary to ensure the accuracy and reliability of data transmission so that the debugger can accurately adjust the tuning screw 4 based on real-time feedback.

[0042] See also Figure 1 , Figure 2 In the exemplary embodiment, the tuning screw 4 is coaxially arranged with the corresponding pressure sensor 8 .

[0043] Among them, since the tuning screw 4 and the corresponding pressure sensor 8 are coaxial, the influence of the lateral force can be minimized, ensuring that the pressure sensor 8 only detects the pressure along the axial direction, thereby improving the measurement accuracy.

[0044] In an exemplary embodiment, in order to prevent the fixture substrate 1 from being damaged due to improper control of the debugging force, the combiner debugging system may also have a safety warning function. When the pressure value detected by the pressure sensor 8 is close to the critical value that may damage the fixture substrate 1, a warning signal is issued.

[0045] In detail, the combiner debugging system may also include an indicator light, which is connected to the processing device 10. The indicator light can display a first color in response to a first trigger signal output by the processing device 10 and display a second color in response to a second trigger signal output by the processing module.

[0046] In which, the processing device 10 can output a first trigger signal when the pressure value output by the pressure sensor 8 is greater than or equal to a first threshold and less than a second threshold, and output a second trigger signal when the pressure value output by the pressure sensor 8 is greater than or equal to a second threshold, and the first threshold is less than the second threshold.

[0047] It is understandable that the target depth may correspond to a pressure range, for example, when the preset target depth is 3 cm, the corresponding pressure range is 5 Newtons to 8 Newtons. Accordingly, for a target depth of 3 cm, the first threshold is 5 Newtons and the second threshold is 8 Newtons.

[0048] Because the target depths of the tuning screws 4 at different positions may be different, the corresponding first threshold value and the second threshold value can be set in advance in the processing device 10 for each pressure sensor 8 at different positions. In this way, the processing device 10 can output an accurate trigger signal corresponding to the pressure value of each pressure sensor 8, triggering the indicator light to issue an alarm.

[0049] For example, when the preset target depth is 3 cm, the corresponding first threshold is 5 Newtons, the second threshold is 8 Newtons, the first color is green, and the second color is red. When the processing device 10 detects that the pressure value of the pressure sensor 8 at this position is greater than or equal to 5 Newtons and less than or equal to 8 Newtons, the first trigger signal is output to control the prompt light to turn on green to prompt the debugger that the tuning screw 4 has been debugged in place. When the processing device 10 detects that the pressure value of the pressure sensor 8 is greater than 8 Newtons, the processing device 10 outputs a second trigger signal to control the prompt light to turn on red for early warning. Based on the prompt light information, the debugger can control the processing device 10 to reversely adjust the tuning screw 4 until the appropriate depth and pressure value are reached.

[0050] It can be seen that the combiner debugging system provided in the embodiment of the present application can use pressure detection to accurately determine the depth of the tuning screw 4, while avoiding damage to the fixture substrate 1 due to excessive force, thereby ensuring the assembly quality and performance stability of the combiner.

[0051] Based on the above embodiments, the present application further provides a combiner debugging method, which is applied to the combiner debugging system described in any of the above embodiments. The method can be executed by the processing device 10. Figure 4 A flowchart of a combiner debugging method according to an embodiment of the present application is shown in FIG. Figure 4 , the combiner debugging method may include the following steps: S100, installing the combiner cover plate 2 with a plurality of tuning screws 4 on the fixture substrate 1; S200, coarsely adjusting each tuning screw 4 on the combiner cover plate 2 until the tuning screw 4 contacts the pressure probe at the corresponding position; S300, obtaining the pressure value output by the pressure sensor 8; S400, fine-tuning the screwing depth of the tuning screw 4 based on the pressure value until the pressure value matches a preset target pressure range, wherein the target pressure range is determined according to the acquired target depths of each tuning screw 4 and a preset mapping relationship.

[0052] In step S100, a plurality of tuning screws 4 are mounted on the combiner cover plate 2 through locking nuts. The specific structure of the fixture substrate 1 can be found in the description of the above embodiment and will not be described again here.

[0053] In an exemplary embodiment, before step S100, the method may further include the following steps: Determine the target depth of each tuning screw 4 based on the simulation results; The target pressure range of each tuning screw 4 is determined based on the target depth and the preset mapping relationship.

[0054] Specifically, advanced electromagnetic simulation technology is used to accurately determine the target depth of the tuning screw 4. Through professional electromagnetic simulation software, the working parameters, material properties and other information of the combiner are input to simulate the working state of the combiner, thereby calculating the optimal depth of the tuning screw 4. The specific simulation process can refer to the existing technology and will not be repeated here.

[0055] After obtaining the target depth of each tuning screw 4 , the processing device 10 may determine the target pressure range of each tuning screw 4 according to a preset mapping relationship and the target depth of each tuning screw 4 .

[0056] Furthermore, in an exemplary embodiment, the processing device 10 can obtain sample pressure values ​​corresponding to the sample tuning screw 4 at different screw-in depths, and then determine a preset mapping relationship between the screw-in depth and the pressure value of the tuning screw 4 based on the sample pressure values ​​and the corresponding screw-in depths.

[0057] In this embodiment, it is assumed that under normal circumstances, there is a certain functional relationship between the depth of the tuning screw 4 and the pressure value detected by the pressure sensor 8. This relationship can be determined through preliminary experiments and calibration. For example, for a specific fixture and tuning screw 4, there may be a pressure value P=kd+b, where P represents the pressure value, d represents the depth of the tuning screw 4, and k and b are coefficients determined by experiments. During the process of screwing in the tuning screw 4, the pressure sensor 8 outputs the pressure value in real time, and the current depth of the tuning screw 4 can be estimated based on this functional relationship.

[0058] It is understandable that the preset mapping relationship can be established using an existing algorithm, and no special limitation is made here.

[0059] In an exemplary embodiment, before step S100, the method may further include the following process: The height of the limit screw 7 in the fixture cavity is adjusted based on the target depth of each tuning screw 4 so that the limit screw 7 is close to the tuning screw 4 at the corresponding position, so that the tuning screw 4 can contact the corresponding pressure sensor 8 during the adjustment process to generate a pressure signal.

[0060] In step S200, during the assembly process of the combiner cover plate 2 and the jig substrate 1, a pressure sensor 8 is installed in the limit screw 7. When the combiner cover plate 2 is tightly combined with the jig substrate 1, the pressure value at this time is recorded. By comparing with the preset pressure range, it is determined whether the tightening degree of the tuning screw 4 is appropriate. If the pressure value is not within the preset range, it means that there may be a problem with the depth of the tuning screw 4, which needs to be checked and adjusted.

[0061] In step S300 , the pressure value output by the pressure sensor 8 may be transmitted to the processing device 10 via a cable, or may be transmitted to the processing device 10 wirelessly.

[0062] In some embodiments, the processing device 10 is connected to a display device 9, and after obtaining the pressure value of the pressure sensor 8, the processing device 10 can further display the pressure value through the display device 9. On this basis, the processing device 10 further transmits the obtained pressure value to the connected display device 9, so that the debugging personnel can visually observe the real-time pressure value of each pressure sensor 8 through the display device 9.

[0063] For the specific implementation of the display device 9 and the processing device 10, reference may be made to the introduction of the above system embodiment, which will not be repeated here.

[0064] In step S400, when the screwing depth of the tuning screw 4 is adjusted, the pressure sensor 8 is in a standby state, and the output pressure value is zero or a reference value close to zero. As the tuning screw 4 is gradually screwed in, the pressure sensor 8 begins to detect the pressure change. When the pressure value is within the preset target pressure range, the depth of the tuning screw 4 is stopped from being adjusted. Specifically: The processing device 10 determines the target pressure range of each tuning screw 4 based on the preset mapping relationship and the target depth of each tuning screw 4; The screwing depth of the tuning screw 4 is finely adjusted so that the pressure value approaches the target pressure range, until the pressure value enters the target pressure range.

[0065] In detail, when the tuning screw 4 approaches or reaches the target depth, the pressure value detected by the pressure sensor 8 will also be in a specific range accordingly. If this pressure value is within the preset pressure range, for example, when the target depth is 3 cm, the corresponding preset pressure range is 5 Newtons to 8 Newtons, the processing device 10 detects that the pressure value of the pressure sensor 8 is greater than 5 Newtons and does not exceed 8 Newtons (to prevent damage to the fixture), indicating that the current depth of the tuning screw 4 has reached the target depth, and controls the tuning screw 4 to stop rotating.

[0066] During the debugging process, when the tuning screw 4 does not contact the corresponding pressure sensor 8, the tuning screw 4 continues to be screwed in; when the tuning screw 4 contacts the corresponding pressure sensor 8 and the pressure value is within the target pressure range, the tuning screw 4 stops being screwed in.

[0067] Among them, when the tuning screw 4 does not contact the corresponding pressure sensor 8, it means that the tuning screw 4 is not screwed in enough depth. Only when the tuning screw 4 contacts the corresponding pressure sensor 8 and the pressure value of the tuning screw 4 is within the preset target pressure range, the tuning screw 4 is stopped from being screwed in.

[0068] As mentioned above, in order to prevent the fixture from being damaged due to excessive force, the system of the present application also sets a safety warning mechanism. Specifically, the combiner debugging system may also include an indicator light, which is connected to the processing device 10; on this basis, the method may also include the following steps: When the pressure value output by the pressure sensor 8 is greater than or equal to the first threshold value and less than the second threshold value, a first trigger signal is output, wherein the indicator light displays a first color in response to the first trigger signal to indicate that the depth value of the tuning screw 4 matches the target depth value; When the pressure value output by the pressure sensor 8 is greater than the second threshold, a second trigger signal is output, wherein the indicator light displays a second color corresponding to the second trigger signal to indicate that the depth value of the tuning screw 4 exceeds the target depth value.

[0069] Among them, the first color can be green, for example, and the second color can be red, for example. When the processing device 10 triggers the prompt light to turn on the green light, it means that the tuning screw 4 has been adjusted in place. For example, the pressure range corresponding to the preset target depth is 5 Newtons to 8 Newtons. When the pressure value detected by the pressure sensor 8 is within this range, the system determines that the depth of the tuning screw 4 meets the requirements, and the green light on the display device 9 turns on. When the pressure value detected by the pressure sensor 8 is close to the critical value that may damage the fixture, the processing device 10 sends a warning signal (i.e., the second trigger signal), and the control prompt light turns on the red light. For example, when the pressure value exceeds a certain proportion (such as 80%) of the preset safety upper limit value, the red light is triggered to flash, reminding the commissioning personnel to stop tightening the screw.

[0070] In addition, in the exemplary embodiment, because a display device 9 and a prompt light are provided, the tuning screw 4 can also be manually adjusted by the debugging personnel during the debugging of the tuning screw 4. Furthermore, a progressive method can be adopted to gradually increase the tightening force. The debugging personnel can adjust the tightening speed and force according to the real-time output of the pressure sensor 8 and the feedback of the signal display system. If the pressure value is close to the trigger range displayed by the green light, the tightening speed can be slowed down and the depth of the tuning screw 4 can be carefully adjusted until the green light comes on. If the pressure value exceeds the preset range or triggers an early warning signal, the debugging personnel can appropriately loosen the tuning screw 4 according to the situation, and then readjust it until the appropriate depth and pressure value are reached. Through the above logical relationship, the depth of the tuning screw 4 can be accurately determined by pressure detection, while avoiding excessive force to damage the jig, thereby ensuring the assembly quality and performance stability of the combiner.

[0071] Further, in an exemplary embodiment, after step S400, the debugging method of the combiner may also include: locking the position of the tuning screw 4 by means of a nut on the tuning screw 4, and when all the tuning screws 4 reach the corresponding target depth, assembling the combiner cover plate 2 equipped with each tuning screw 4 on the corresponding combiner cavity, and performing sealing treatment to form a combiner.

[0072] In this embodiment, the tuning screw 4 can be locked in position by using a nut, which is convenient for disassembly and assembly of the tuning screw 4 .

[0073] When all the tuning screws 4 have reached the target depth, the combiner cover plate 2 equipped with the tuning screws 4 can be directly assembled on the corresponding combiner cavity (the extension length of each tuning screw 4 has been debugged in the jig). In this way, professional technicians are no longer needed to perform debugging, which effectively simplifies the debugging process and saves manpower and time resources.

[0074] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
