[0029] Reference Figure 1 to Figure 4, the embodiment of the present application provides a combiner debugging fixture, which is used to adjust the depth of multiple adjustment screws 4 set on the combiner cover plate 3, each adjustment screw 4 has the freedom to rotate around its own axis, and the outer periphery of each adjustment screw 4 is screwed with a nut 5 to lock or release the rotational freedom of the adjustment screw 4. The debugging fixture may include a support cavity 1, an intelligent board 8, a debugging component 6, a plurality of digital potentiometers 6c and a potentiometer control module 8c, the support cavity 1 is used to install the combiner cover plate 3; the intelligent board 8 is arranged on the side of the combiner cover plate 3 away from the support cavity 1 and has a gap with the combiner cover plate 3, the intelligent board 8 is provided with mounting holes corresponding to the adjustment screws 4, and the intelligent board 8 is provided with a microcontroller 8d; the debugging component 6 corresponds to the mounting holes one by one and is penetrated at the corresponding mounting holes, and the adjustment screws 4 is connected to a debugging component 6 together with the corresponding nut 5, and the debugging component 6 drives the nut 5 to release the rotational freedom of the adjusting screw 4 and drives the adjusting screw 4 to rotate; multiple digital potentiometers 6c correspond to multiple debugging components 6 one by one and are arranged at the corresponding debugging components 6, and the debugging components 6 drive the sliding contacts of the corresponding digital potentiometers 6c to slide when working; the potentiometer control module 8c is electrically connected to each digital potentiometer 6c, and is used to obtain the output signal of the digital potentiometer 6c to determine the current depth of the corresponding adjusting screw 4; wherein, the microcontroller 8d is electrically connected to the debugging component 6 and the potentiometer control module 8c, and is used to obtain the current depth and target debugging depth of each adjusting screw 4, and output a control signal to the corresponding debugging component 6 based on the current depth and the corresponding target debugging depth to adjust the depth of the adjusting screw 4 at the corresponding position.

[0030] A combiner debugging fixture proposed in an embodiment of the present application first obtains the target debugging depth of the adjustment screw 4 of the corresponding combiner through simulation design, then connects the combiner cover plate 3 to the support cavity 1, and connects the smart board 8 to the side of the combiner cover plate 3 away from the support cavity 1. At this time, the debugging component 6 can be controlled to rotate the nut 5 to release the rotational freedom of the adjustment screw 4, and the adjustment screw 4 is further rotated by the debugging component 6 to rotate the current depth of the adjustment screw 4 to the target debugging depth. The digital potentiometer 6c changes the effective access length of its internal resistor following the work of the debugging component 6, causing the resistance value to change. The potentiometer control module 8c determines the current depth of each adjustment screw 4 based on the change of each digital potentiometer 6c. After the current depth is equal to the target debugging depth, the corresponding debugging component 6 drives the corresponding nut 5 to tighten the rotational freedom of the corresponding adjustment screw 4 to complete the adjustment of the corresponding adjustment screw 4. When the adjustment of each adjustment screw 4 is completed, the combiner cover plate 3 can be installed on the combiner cavity to complete the combiner debugging, and the work efficiency is high and the debugging consistency of each combiner is strong.

[0031] The debugging process of the adjusting screw 4 on the combiner cover plate 3 is controlled by the microcontroller 8d, which may be a single chip microcomputer.

[0032] Furthermore, the support cavity 1 can also directly use the combiner cavity, that is, first assemble the combiner cavity and the combiner cover plate 3, and then install the smart board 8 on the side of the combiner cover plate 3 away from the combiner cavity, which is more efficient.

[0033] It should be noted that the adjusting screw 4 is the tuning screw, and the depth of the adjusting screw 4 refers to the length of the adjusting screw 4 on the side of the combiner cover 3 facing the support cavity 1 in a direction perpendicular to the combiner cover 3. In other words, it is the length of the adjusting screw 4 inside the support cavity 1.

[0034] It should be understood that before rotating each adjusting screw 4, each adjusting screw 4 is threadedly connected to the combiner cover plate 3. At this time, the depth of each adjusting screw 4 is the same, which is recorded as the initial depth. At this time, the initial depth is greater than or equal to 0. The above-mentioned current depth and target debugging depth do not include the initial depth, that is, the sum of the above-mentioned current depth and the initial depth is the actual depth, and the sum of the target debugging depth and the initial depth is the actual target debugging depth; when the current depth is equal to the target debugging depth, the actual depth is also the same as the actual target debugging depth, and the adjustment of the corresponding adjusting screw 4 can be completed.

[0035] It should be understood that if Figure 2 As shown, there is a gap between the smart board 8 and the combiner cover plate 3, and the gap here mainly provides a movable space for the adjusting screw 4 and the debugging component 6; how to set the smart board 8 so that there is a gap between the smart board 8 and the combiner cover plate 3 can be referred to the existing technology and will not be described in detail here.

[0036] Furthermore, the smart board is a PCBA (Printed Circuit Board Assembly) board, and the smart board 8 can also be provided with a Bluetooth module 8e, a WIFI module 8f, an Ethernet port 8g, a USB port 8h and a power input port 8i, thereby further improving the intelligence level of the smart board 8, wherein the power input port 8i is used to provide power to the electrical components on the combiner debugging fixture, and the power input port 8i is connected to an external power supply.

[0037] The digital potentiometer 6c is connected to the microcontroller via a digital communication bus such as I2C, SPI, etc. These buses can support multiple devices to be connected to the same bus, so as to realize independent control of multiple holes.

[0038] At the same time, proximity sensors and photoelectric sensors can also be used to detect the position and state of the hole. The sensor is installed on the smart board to monitor the changes in the hole position in real time, and feed back the information to the microcontroller 8d, which is further fed back to the background server by the microcontroller 8d.

[0039] like Figure 2As shown, in the exemplary embodiment, the mounting holes correspond to the adjusting screws 4 one by one, so that each adjusting screw 4 has a debugging assembly 6 corresponding thereto, and each adjusting screw 4 can be adjusted;

[0040] In an exemplary embodiment, a plurality of mounting holes are arranged at intervals in the length direction and the width direction of the smart board 8 , and the intervals between adjacent mounting holes are the same.

[0041] Specifically, multiple mounting holes are densely arranged in the length and width directions of the smart board 8, that is, multiple debugging components 6 are densely arranged in the length and width directions of the smart board 8, so that when the combiner debugging fixture is used, each adjusting screw 4 on the combiner cover plate 3 is only connected to part of the debugging components 6, and at this time, the depth of each adjusting screw 4 on the combiner cover plate 3 can still be adjusted; further, when replacing other types of combiners, each adjusting screw 4 on the combiner cover plate 3 can still be connected to part of the multiple debugging components 6 to complete the depth adjustment of the adjusting screw 4, that is, the arrangement of multiple debugging components 6 covers a variety of arrangement methods of the adjusting screws 4 on the combiner cover plates 3, so that the combiner debugging fixture can adjust various types of combiners, and has a wider range of applications.

[0042] refer to Figure 1 and Figure 2 In an exemplary embodiment, the debugging jig may further include a jig cavity 7 and a jig cover 9, wherein the jig cavity 7 is disposed on the side of the combiner cover 3 away from the support cavity 1; the jig cover 9 is sealed and connected to the jig cavity 7; wherein the smart board 8 is disposed in the jig cavity 7, and the jig cavity 7 has a plurality of through holes corresponding to the plurality of mounting holes, and the through holes and the mounting holes are opposite to each other in the thickness direction of the smart board 8.

[0043] Specifically, Figure 1 and Figure 2 As shown, the jig cavity 7 is arranged on the side of the combiner cover 3 away from the support cavity 1, and there is a gap between the jig cavity 7 and the combiner cover 3. At this time, the smart board 8 is arranged inside the jig cavity 7 on the side close to the combiner cover 3. Through holes corresponding to the mounting holes are opened on the jig cavity 7, so that the debugging component 6 can pass through the through holes to connect with the adjusting screw 4 and the nut 5. The jig cover 9 seals the jig cavity 7, so that the smart board 8 is in a relatively closed environment, which has a better protection effect on the smart board 8.

[0044] It should be noted that at this time, it is only necessary to add a supporting structure between the jig cavity 7 and the combiner cover plate 3 to create a gap between the jig cavity 7 and the combiner cover plate 3. There are many existing solutions for the specific support, which will not be explained in detail here, as long as it does not affect the movement of the adjusting screw 4 and the debugging component 6 in the gap between the jig cavity 7 and the combiner cover plate 3.

[0045] Furthermore, for the modules on the smart board 8 that are connected to the outside, a connection port can be opened at a corresponding position on the fixture cavity 7 .

[0046] refer to Figure 2 to Figure 4 In an exemplary embodiment, the debugging component 6 may include a rotary telescopic motor 6a and a torque motor 6b. The rotary telescopic motor 6a is inserted through the through hole and the mounting hole and the output end is connected to the adjusting screw 4. The rotary telescopic motor 6a drives the adjusting screw 4 to rotate, wherein the sliding contact of the digital potentiometer 6c is rotatably connected to the output shaft of the rotary telescopic motor 6a, so that the sliding contact of the corresponding digital potentiometer 6c is driven to slide when the rotary telescopic motor 6a is working; the torque motor 6b is arranged on the side of the fixture cavity 7 facing the combiner cover plate 3 and is connected to the nut 5. The torque motor 6b drives the nut 5 to rotate to lock or release the rotational freedom of the adjusting screw 4.

[0047] Specifically, Figure 2 to Figure 4 As shown, the rotary telescopic motor 6a is connected to the adjusting screw 4, and the torque motor 6b is connected to the nut 5. The torque motor 6b drives the nut 5 to rotate to lock or release the rotational freedom of the adjusting screw 4. The rotary telescopic motor 6a drives the adjusting screw 4 to rotate so that the adjusting screw 4 moves along its own axial direction, thereby changing the depth of the adjusting screw 4; wherein, before the rotary telescopic motor 6a drives the adjusting screw 4 to rotate, the torque motor 6b drives the nut 5 to rotate to release the rotational freedom of the adjusting screw 4; when the rotary telescopic motor 6a drives the adjusting screw 4 to rotate and reaches the target debugging depth, the torque motor 6b drives the nut 5 to rotate to lock the rotational freedom of the adjusting screw 4.

[0048] It should be noted that a structure that cooperates with the adjusting screw 4 can be set on the output shaft of the rotating and telescopic motor 6a. For example, a straight groove is set at the end of the adjusting screw 4 away from the supporting cavity 1, and the end of the output shaft of the rotating and telescopic motor 6a can be fixed with a raised structure that cooperates with the straight groove, so that when the rotating and telescopic motor 6a rotates, the adjusting screw 4 can be driven to rotate. Of course, the end of the adjusting screw 4 away from the supporting cavity 1 can also be a cross groove, a hexagonal groove, etc.

[0049] In addition, multiple sleeves can be set on the side of the fixture cavity 7 facing the combiner cover plate 3. The sleeves correspond to the through holes one by one and are located on the side of the corresponding through holes away from the mounting hole. The sleeves have the freedom to rotate around the thickness direction of the smart board 8. The sleeves are sleeved on the outer periphery of the nut 5. The torque motor 6b can drive the sleeve to rotate through structures such as gear transmission, and further drive the nut 5 to rotate, thereby locking or releasing the rotation freedom of the adjusting screw 4.

[0050] Exemplarily, the gear transmission structure may be configured as follows: the outer periphery of the sleeve is sleeved with the driven gear, the output shaft of the torque motor is sleeved with the driving gear, and the driving gear is meshed with the driven gear.

[0051] Furthermore, the sliding contact of the digital potentiometer 6c is rotatably connected to the output shaft of the rotary telescopic motor 6a, so that when the rotary telescopic motor 6a is working, the sliding contact of the corresponding digital potentiometer 6c is driven to slide. When the sliding contact of the digital potentiometer 6c slides, the effective access length of the internal resistor of the digital potentiometer 6c is changed, causing the resistance value to change. The potentiometer control module 8c is connected to each digital potentiometer 6c in a constant current circuit. The potentiometer control module 8c can determine the voltage change of each digital potentiometer 6c through the resistance value change of each digital potentiometer 6c, and then determine the voltage change of each digital potentiometer 6c based on the voltage change and the adjustment screw 4. The relationship between the current depths further determines the current depths of each adjusting screw 4 and feeds back to the microcontroller 8d; wherein, a rotating ring can be sleeved on the output shaft of the rotating and telescopic motor 6a, the rotating ring is rotatably connected to the rotating and telescopic motor, and the rotating ring is connected to the sliding contact of the digital potentiometer 6c. In this way, when the rotating and telescopic motor 6a is working, it will drive the rotating ring to move, and the rotating ring and the output shaft of the rotating and telescopic motor 6a will rotate relative to each other. At the same time, the rotating ring further drives the sliding contact of the digital potentiometer 6c to move, thereby making the resistance value of the digital potentiometer 6c change accordingly according to the depth change of the adjusting screw 4.

[0052] In addition, the digital potentiometer 6c can also be a rotary digital potentiometer, and the output shaft of the rotary telescopic motor 6a can also be converted into a rotation angle change of the rotating shaft of the digital potentiometer through gear transmission or the like, so that the resistance value of the digital potentiometer changes accordingly. At this time, the driving gear can be spline-connected with the output shaft of the rotary telescopic motor 6a, that is, the output shaft of the rotary telescopic motor 6a can drive the driving gear to rotate but cannot drive the driving gear to move axially along the output shaft of the rotary telescopic motor 6a. The driving gear is meshed with the driven gear, and the driven gear is sleeved on the outer periphery of the rotating shaft of the digital potentiometer.

[0053] It should be understood that if the circuit uses a constant current source, the potentiometer control module 8c will detect a voltage change after the resistance value of the digital potentiometer 6c changes; if the circuit uses a constant voltage source, the potentiometer control module 8c will detect a current change after the resistance value of the digital potentiometer 6c changes. This embodiment is only illustrative of the constant current source as an example, and does not constitute a limitation to the present application.

[0054] refer to Figure 3 and Figure 4In an exemplary embodiment, the debugging component 6 may further include a plurality of electromagnetic relays 6e, which correspond one-to-one to the plurality of debugging components 6 and are arranged at the corresponding debugging components 6, and the electromagnetic relays 6e are electrically connected to the rotary telescopic motor 6a and the torque motor 6b in the corresponding debugging component 6; the smart board 8 also includes a relay control module 8b, which is electrically connected to the microcontroller 8d; wherein the relay control module 8b is used to respond to the switch signal output by the microcontroller 8d to control the corresponding electromagnetic relay 6e to be turned on or off.

[0055] Specifically, the relay control module 8b can control each electromagnetic relay 6e to be turned on or off. When the electromagnetic relay 6e is turned on, the rotating telescopic motor 6a and the torque motor 6b are powered; when the electromagnetic relay 6e is turned off, the rotating telescopic motor 6a and the torque motor 6b are powered off. The corresponding rotating telescopic motor 6a and the torque motor 6b control the adjusted adjustment screw 4. For example, for the adjustment screw 4 that does not need to be adjusted, the corresponding electromagnetic relay 6e can be disconnected. In addition, for the adjustment screw 4 that has been adjusted to the target debugging depth, the corresponding electromagnetic relay 6e can also be disconnected to stop the adjustment, which is more convenient to use.

[0056] refer to Figure 3 and Figure 4 In an exemplary embodiment, the debugging component 6 may further include a plurality of labels 6d, which correspond one-to-one to the plurality of mounting holes and are arranged at the corresponding mounting holes, wherein the labels 6d store the position information of the corresponding mounting holes; the smart board 8 also includes a reader / writer 8a, which is electrically connected to the microcontroller 8d, and the reader / writer 8a is used to feed back the position information of each mounting hole to the microcontroller 8d; wherein the microcontroller 8d is also used to associate the position information with each adjusting screw 4.

[0057] Specifically, the tag 6d is an RFID (Radio Frequency Identification) tag, the reader / writer 8a is an RFID reader / writer, and the tag 6d can also be electrically connected to the potentiometer control module 8c, so that the tag 6d stores the position information and depth information of the corresponding adjusting screw 4, and the reader / writer 8a reads the information of the tag 6d at each mounting hole and provides feedback to the microcontroller 8d; the microcontroller 8d is also used to associate the position information with each adjusting screw 4. In other words, the microcontroller 8d associates the position information obtained from the reader / writer 8a with the rotary telescopic motor 6a and the torque motor 6b in each debugging component 6. When the microcontroller 8d receives an adjustment instruction with the RFID tag information, it can compare the position information in the adjustment instruction with the position information obtained from the reader / writer 8a, thereby sending the adjustment instruction to the associated rotary telescopic motor 6a and the torque motor 6b, so that one or several adjusting screws 4 can be adjusted individually, which is more convenient to use.

[0058] It should be understood that, further, the microcontroller 8d will associate the position information obtained from the reader / writer 8a with the rotary telescopic motor 6a, the torque motor 6b and the electromagnetic relay 6e in each debugging component 6. In this way, when it is necessary to control a certain electromagnetic relay 6e to be turned on or off, it can refer to the above-mentioned instructions sent to the corresponding electromagnetic relay 6e through the electromagnetic relay control module 8b.

[0059] In addition, coding technology can be used to assign a unique identifier to each mounting hole, and the identifier can be a digital code, a barcode or a two-dimensional code, etc. By scanning or reading these identifiers, the mounting hole can be quickly and accurately determined to facilitate adjustment of the adjustment screw 4 at the corresponding mounting hole.

[0060] As described above, the combiner debugging fixture provided in the present application can be adapted to different combiners. The specific principle by which the combiner debugging fixture can adjust different combiners is exemplified below.

[0061] For example, combiner A has 30 tuning screws and combiner B has 40 tuning screws. When the combiner debugging fixture adjusts combiner A, the target debugging depth of the 30 tuning screws of combiner A is first determined according to the simulation design, and then the cover of combiner A is connected to the combiner debugging fixture. At this time, the multiple groups of debugging components 6 on the combiner debugging fixture cover the 30 tuning screws, that is, each tuning screw is connected to the corresponding debugging component. When adjusting, the microcontroller 8d obtains the current depth of the 30 tuning screws through the potentiometer control module 8c, and then outputs a control signal to the corresponding debugging component 6 based on the target debugging depth of each tuning screw, so that the 30 debugging components 6 drive the corresponding 30 tuning screws to rotate, so that the current depth of the 30 tuning screws approaches the corresponding target debugging depth, until the current depth of the 30 tuning screws is equal to the corresponding target debugging depth, so that the depth adjustment of the 30 tuning screws on combiner A can be completed.

[0062] When the combiner debugging fixture adjusts the combiner B, the target debugging depth of the 40 tuning screws of the combiner B is first determined according to the simulation design, and then the cover of the combiner B is connected to the combiner debugging fixture. At this time, the multiple groups of debugging components 6 on the combiner debugging fixture cover the 40 tuning screws, that is, each tuning screw is connected to the corresponding debugging component. When adjusting, the microcontroller 8d obtains the current depth of the 40 tuning screws through the potentiometer control module 8c, and then outputs a control signal to the corresponding debugging component 6 based on the target debugging depth of each tuning screw, so that the 40 debugging components 6 drive the corresponding 40 tuning screws to rotate, so that the current depth of the 40 tuning screws approaches the corresponding target debugging depth, until the current depth of the 40 tuning screws is equal to the corresponding target debugging depth, so that the depth adjustment of the 40 tuning screws on the combiner A can be completed.

[0063] It should be noted that how the microcontroller 8d outputs control signals to the corresponding debugging components can refer to the above-mentioned solution of the tag 6d and the reader / writer 8a, which will not be repeated here; in addition, the microcontroller 8d is connected to the background server, and the user can control the combiner debugging fixture through the background server and input the target debugging depth of each tuning screw. Assuming that there are 100 debugging components on the combiner debugging fixture, taking combiner A as an example, when the 30 tuning screws of combiner A are connected to the corresponding debugging components, only the corresponding target debugging depths need to be input for the 30 debugging components corresponding to the tuning screws at the background server. In this way, the adjustment instruction sent by the background server to the microcontroller 8d carries the corresponding RFID tag information, and then the microcontroller 8d can output control signals to the corresponding debugging components based on the RFID tag information.

[0064] refer to Figure 5On the basis of the above embodiment, the embodiment of the present application further provides a combiner debugging method, which is applied to the above combiner debugging fixture. The combiner debugging method is executed by the microcontroller 8d. The combiner debugging method may specifically include the following steps:

[0065] Step S100, obtaining the target debugging depth and current depth of each adjusting screw 4 on the combiner, wherein the current depth is determined by the potentiometer control module 8c based on the output signal of each digital potentiometer 6c;

[0066] Step S200, comparing the current depth of the corresponding adjusting screw 4 with the target debugging depth;

[0067] Step S300: Send a control signal to the corresponding debugging component 6 based on the comparison result, wherein the control signal is used to instruct the debugging component 6 to drive the adjusting screw 4 to rotate so that the current depth of the corresponding adjusting screw 4 is equal to the target debugging depth.

[0068] The microcontroller 8d is specifically electrically connected to the rotary telescopic motor 6a and the torque motor 6b in the debugging component 6, so that the microcontroller 8d sends a control signal to the debugging component 6;

[0069] In step S100, the target debugging depth of each adjusting screw 4 on the combiner can be obtained by simulating the combiner, and the potentiometer control module 8c can determine the output signal of each digital potentiometer 6c through the change in the resistance value of each digital potentiometer 6c (as described above, when the circuit is a constant current source structure, the output signal is specifically a voltage signal; when the circuit is a constant voltage source structure, the output signal is specifically a current signal, and this application only takes the output signal as a voltage signal as an example for illustrative explanation), and then based on the relationship between the voltage change and the current depth of each adjusting screw 4, the current depth of each adjusting screw 4 is further determined and fed back to the microcontroller 8d.

[0070] In an exemplary embodiment, the control signal may include a first control signal, a second control signal, and a third control signal; step S300 may specifically include the following steps:

[0071] Step S310: If the current depth of the corresponding adjusting screw 4 is less than the target debugging depth, a first control signal is sent to the debugging component 6, wherein the first control signal is used to instruct the debugging component 6 to drive the adjusting screw 4 to rotate forward so as to increase the current depth of the adjusting screw 4;

[0072] Step S320: If the current depth of the corresponding adjusting screw 4 is equal to the target debugging depth, a second control signal is sent to the debugging component 6, wherein the second control signal is used to instruct the debugging component 6 to stop working;

[0073] Step S330: If the current depth of the corresponding adjusting screw 4 is greater than the target debugging depth, a third control signal is sent to the debugging component 6, wherein the third control signal is used to instruct the debugging component 6 to drive the adjusting screw 4 to reverse so that the current depth of the adjusting screw 4 is reduced.

[0074] Specifically, it is stipulated that when the adjusting screw 4 rotates forward, the current depth of the adjusting screw 4 increases, and when the adjusting screw 4 rotates reversely, the current depth of the adjusting screw 4 decreases; the specific control of the forward or reverse rotation of the adjusting screw 4 can be controlled by the forward or reverse rotation of the output shaft of the rotating telescopic motor 6a. For the working method of the torque motor 6b driving the nut 5 before and after the rotating telescopic motor 6a works, reference can be made to the introduction of the above embodiment, which will not be repeated here.

[0075] In step S310, when the current depth of the corresponding adjustment screw 4 is less than the target debugging depth, the microcontroller 8d sends a first control signal to the reader / writer 8a or the corresponding debugging component 6, and the rotating telescopic motor 6a drives the adjustment screw 4 to rotate forward, so that the current depth approaches the target debugging depth. When the reader / writer 8a receives the first control signal, it sends the first control signal to the debugging component 6 corresponding to the corresponding tag 6d.

[0076] In step S320, when the current depth of the corresponding adjustment screw 4 is equal to the target debugging depth, the microcontroller 8d sends a second control signal to the reader / writer 8a or the corresponding debugging component 6, and the rotary telescopic motor 6a stops working to complete the depth adjustment of the corresponding adjustment screw 4. When the reader / writer 8a receives the second control signal, it sends a second control signal to the debugging component 6 corresponding to the corresponding tag 6d.

[0077] In step S330, when the current depth of the corresponding adjustment screw 4 is greater than the target debugging depth, the microcontroller 8d sends a third control signal to the reader / writer 8a or the corresponding debugging component 6, and the rotating telescopic motor 6a drives the adjustment screw 4 to reverse, so that the current depth approaches the target debugging depth. When the reader / writer 8a receives the third control signal, it sends the third control signal to the debugging component 6 corresponding to the corresponding tag 6d.

[0078] In an exemplary embodiment, the potentiometer control module 8c determines the current depth based on the output signal of each digital potentiometer 6c using the following formula, wherein the output signal of each digital potentiometer 6c is the output voltage:

[0079] D=kU+b

[0080] Where: U represents the output voltage; D represents the current depth; k and b are constants.

[0081] Specifically, the values ​​of k and b in the formula can be determined through multiple experiments. For example, multiple data points (D i, U i ) into the linear equation D i =kU i +b, list multiple equations, and then determine the values ​​of k and b. Make the error square sum ∑(D i -(kU i +b))² is minimized, thus obtaining the most accurate linear relationship.

[0082] Specifically, when the rotary telescopic motor 6a is working, the effective access length of the resistor of the digital potentiometer 6c changes, which further causes the resistance value to change, and finally causes the voltage across the digital potentiometer 6c to change. The potentiometer control module 8c detects the voltage change in real time and sends the current voltage value to the microcontroller 8d. The microcontroller 8d determines the current depth of the corresponding adjustment screw 4 based on the current voltage value, and compares the current depth with the target debugging depth to further determine the screwing direction and screwing depth of the corresponding adjustment screw 4, and then outputs the corresponding control signal.

[0083] Furthermore, if an abnormal situation occurs during the adjustment process, such as a failure of the digital potentiometer 6c, the current depth of the adjustment screw 4 cannot reach the target debugging depth, or the actual current depth of each adjustment screw 4 and the linear relationship between the voltage output by the corresponding digital potentiometer 6c have a large deviation, the microcontroller 8d can send an alarm message to the background server so that adjustment processing can be carried out in time. At the same time, the experiment and data analysis can be repeated to adjust the coefficient of the linear relationship, ultimately improving the accuracy of the adjustment of each adjustment screw 4, and further improving the production efficiency and product quality of the combiner.

[0084] Furthermore, the microcontroller 8d is connected to the background server via wired (such as Ethernet, USB, etc.) or wireless (such as Wi-Fi, Bluetooth, etc.) means, receives control instructions and feeds back the depth information and position information of each current adjusting screw 4 to the background server, so that the background operator can conduct real-time monitoring, which is more convenient to use. The background can use a graphical interactive interface and a parameter setting window to facilitate the operator to set and adjust the target debugging depth of the corresponding adjusting screw 4.

[0085] Furthermore, data transmission between the background and the smart board 8 is realized through a reliable communication connection. It is ensured that the instructions can be quickly and accurately transmitted to the smart board 8, and the hole status information can be fed back to the background in time to achieve the real-time and accuracy of intelligent adjustment.

[0086] Specifically, select Ethernet, USB, Wi-Fi, and Bluetooth communication protocols and technologies, and confirm factors such as communication speed, stability, distance, and power consumption according to actual needs; use technologies such as data verification and retransmission mechanisms to deal with interference and errors in communication, establish stable communication links, and ensure the reliability of data transmission; use a distributed communication architecture to distribute communication tasks to multiple nodes, improve communication efficiency, optimize the communication architecture, and reduce communication delays.

[0087] In addition, on the background server, only authorized users can access and control the depth adjustment function of the adjusting screw 4. By inputting the simulation data into the software system, the intelligent debugging fixture can automatically complete the depth adjustment of each adjusting screw 4, and adopt user authentication, authorization mechanism and other technologies to ensure the security of the system; a data backup and recovery mechanism can also be established to prevent data loss; regularly back up the depth information and position information of each adjusting screw 4 so that data can be quickly restored in case of system failure; perform system stability testing and optimization to ensure that the system can run stably under various working conditions; adopt stress testing, fault simulation and other technologies to detect the stability of the system and repair potential problems in a timely manner.

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.
