Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 2 is a schematic flow chart of an embodiment of an automatic cavity filter debugging method according to the present invention. The automatic debugging method of the embodiment comprises the following steps:
s101: and correcting a coordinate system according to the filter engineering design file to determine that the X and Y coordinate position information of the engineering design file corresponds to the X and Y coordinate information of the debugging platform. The filter engineering design file can be a design drawing of a cavity and a cover plate of the filter, and X and Y coordinate information of an adjusting screw hole in the cover plate is led in to serve as X and Y coordinate information of the adjusting screw.
When debugging is carried out, a cavity filter engineering design file is imported, an X coordinate system and a Y coordinate system (figure 3) of a cavity filter adjusting screw engineering design file are inconsistent with an X coordinate system and a Y coordinate system (figure 4) of artificial intelligent automatic debugging and cannot be directly quoted, single-point or multi-point correction can be carried out through the coordinate system, the offset of the engineering design file coordinate system and a debugging coordinate system of a debugging platform is determined, and finally X/Y coordinate position information (figure 4) of an adjusting screw in the debugging platform coordinate system is determined.
Step S102: and setting the debugging sequence of all the adjusting screws. Specifically, all the adjusting screws of the cavity filter are numbered, and the debugging sequence of the adjusting screws is set (see fig. 5). Usually, the debugging sequence of cavity filter adjusting screws is regular, and generally, odd adjusting screws are debugged first, and even adjusting screws are debugged only after the performance is debugged to a certain requirement, and the cavity filter can also have other special debugging sequences, so the adjusting screws need to be numbered, the debugging rules are set through numbering according to the corresponding debugging rules of the filter, and the debugging sequence of the adjusting screws is set.
It is understood that the debugging sequence is set by adjusting the screw number in the present embodiment, and in other embodiments, the debugging sequence may also be set by a template, a mold, a tool, a fixture, etc. (including but not limited to). Of course, the step of setting the debugging order may be omitted as needed, and the debugging may be performed directly according to a fixed order.
Step S103: and acquiring the preset height information of all the adjusting screws according to the preset Z coordinate height recording file. Specifically, the preset Z coordinate height recording file stores position height information of all adjustment screws of the cavity filter with the same model and batch and excellent performance, as shown in fig. 6.
Specifically, all the preset screw height information (preset Z position height) is automatically read, and before the cavity filter is debugged for the first time, the Z position height information of all the adjusting screws of the cavity filter in the same type batch and with excellent performance is automatically read and used as the preset Z position height of all the adjusting screws, and is recorded in a preset Z coordinate height recording file in a file form.
The actual test step of the pre-positioning Z position height information only needs to be executed once, cavity filters in the same model and batch are debugged every time, and all the pre-positioning Z position height information of the adjusting screws can be obtained only by automatically reading file records.
The pre-positioning Z position height corresponds to the height of the adjusting screw in the inner cavity of the cavity filter, so that the corresponding equivalent capacitance and inductance are influenced, the performance of the cavity filter is determined, and the pre-positioning Z position height information recorded by the file is the height of all the adjusting screws of the cavity filter in the same model batch with excellent performance, so that the pre-positioning Z position height of the filter can obtain better initial performance of the filter, and higher debugging efficiency is realized. The present embodiment records the pre-positioning Z position height information in a file form, of course. In other embodiments, the predetermined position information may be recorded by using a template, a mold, a tool, a fixture, or the like (including but not limited to), or by using a depth, a length, a height, or the like (including but not limited to), so as to achieve higher debugging efficiency.
S104: and adjusting all the adjusting screws to preset positions corresponding to the preset height information. Specifically, the method comprises the following steps:
firstly, the cavity filter is fixed on a machine platform of a debugging platform. Because the cavity filter can be connected with testing equipment such as a network analyzer, the cavity filter is fixedly installed, and the risk that the radio frequency connecting cable for connecting the cavity filter and the network analyzer is poor in connection or damaged due to long-term use is avoided.
And then, according to the coordinate information determined in the step S101, the servo drive system drives the screw rotation actuating mechanism and the nut sleeve actuating mechanism to be positioned at the position corresponding to the coordinate information. In this embodiment, an adjusting screw with a specified number is selected, the X/Y coordinate position determined in step S101 is read, and the screw rotation executing mechanism and the nut sleeve executing mechanism are positioned to the X/Y coordinate position of the artificial intelligence automatic debugging coordinate system through the servo driving system.
Then, the screw rotation actuator and the nut-socket actuator are driven to move downward (move downward along the Z-axis); the screw rotating actuating mechanism is firstly contacted with the adjusting screw, matched with the adjusting screw and inserted into the adjusting screw, then the nut sleeve actuating mechanism moves downwards along the Z-axis for a certain position, is contacted with the fixed nut, is matched with the fixed nut and is sleeved into the fixed nut, and the fixed nut is unscrewed after the completion; the screw rotation executing mechanism rotates the adjusting screws to the height position (height in the Z direction) corresponding to the preset height information determined in step S103, then the nut-and-sleeve executing mechanism locks the fixing nuts, the screw rotation executing mechanism and the nut-and-sleeve executing mechanism move upwards, and the above steps are repeated to enable all the adjusting screws to reach the preset position.
In this embodiment, all the adjusting screws are set to the preset Z position height in an automatic manner, and it is needless to say that the preset depth, length, height, etc. (including not limited) of the adjusting screws can be set manually (including not limited) automatically, semi-automatically, or automatically (including not limited) through, for example, a template, a mold, a tool, a clamp, etc., so that higher debugging efficiency is realized.
Step S105: adjusting screws are adjusted up and down in the height direction of the preset position, and the performance and change information of the cavity filter are monitored in real time through a network analyzer and are conveyed to a control device.
Specifically, first, according to the coordinate information determined in step S101, the servo drive system drives the screw rotation actuator and the nut sleeve actuator to position the screw rotation actuator and the nut sleeve actuator at the position corresponding to the coordinate information. In this embodiment, an adjusting screw with a specified number is selected, the X/Y coordinate position determined in step S101 is read, and the screw rotation executing mechanism and the nut sleeve executing mechanism are positioned to the X/Y coordinate position of the artificial intelligence automatic debugging coordinate system through the servo driving system.
Then, the screw rotation actuator and the nut-socket actuator are driven to move downward (move downward along the Z-axis); the screw rotating actuating mechanism is firstly contacted with the adjusting screw, matched with the adjusting screw and inserted into the adjusting screw, then the nut sleeve actuating mechanism moves downwards for a certain position to be contacted with the fixed nut, matched with the fixed nut and sleeved in the fixed nut, and the fixed nut is unscrewed after the completion; the screw rotating executing mechanism rotates the adjusting screw to move up and down at a preset position, and in the process of moving up and down, the performance and change information of the cavity filter are monitored in real time through the network analyzer and are conveyed to the control device. Specifically, the screw actuating mechanism rotates the adjusting screw to enable the adjusting screw to move downwards for a certain position along a preset height position of the Z axis, and then the screw actuating mechanism reversely rotates the adjusting screw to enable the adjusting screw to move upwards along the Z axis and stop at the position height of the Z axis which is larger than the preset height position for a certain position. And in the process that the adjusting screw moves downwards and upwards near the pre-positioning height along the Z axis, the network analyzer monitors the performance and the change of the cavity filter in real time, and transmits the real-time performance change test result of the cavity filter in the pre-debugging process to the control device through the special data interface. The embodiment adopts an artificial intelligence automatic mode, the adjusting screw is debugged nearby a preset position, and the network analyzer monitors the performance and the change of the cavity filter in real time. Of course, in other embodiments, the performance and changes may be monitored in real time by a network analyzer by adjusting screws near predetermined positions, along the depth, length, height, etc. (including but not limited to) directions, automatically, semi-automatically, manually (including but not limited to) moving pre-debug, for example, a template, a mold, a tool, a fixture, etc. (including but not limited to).
S106: the control device analyzes the performance and change information of the real-time monitoring cavity filter, and judges and determines the debugging and determining position of the adjusting screw; and updating the predetermined altitude information with the altitude information of the commissioning determined location. In this embodiment, the height position of the Z coordinate of the height of the adjusting screw is determined by artificial intelligence, and the control device receives the real-time test result of the performance change of the cavity filter generated in the pre-debugging process in step S105 through a dedicated data interface, and the cavity filter is debugged very sensitively to the debugging height of the adjusting screw, and has many performance indexes, high requirements, VSWR, insertion loss, flatness, isolation, and the like. In this embodiment, an artificial intelligence machine learning manner is adopted to establish a multidimensional performance index quantization model, determine an adjustment screw debugging position at which an optimal pre-estimated quantization model index can be obtained, control a screw executing mechanism to rotate an adjustment screw to the position, and automatically update the position to a pre-positioning Z position height for the next automatic debugging of the adjustment screw. Then the nut sleeve actuating mechanism locks and fixes the nut, the screw rotation actuating mechanism and the nut sleeve actuating mechanism move upwards along the Z-axis direction, and one-time artificial intelligence automatic debugging of the adjusting screw is completed. In this embodiment, an artificial intelligence automatic manner is adopted, and the optimal position of the adjusting screw is determined after the adjusting screw is debugged in the vicinity of the pre-debugging height, but in other embodiments, the optimal position of the adjusting screw may also be determined after manual (including without limitation) pre-debugging, for example, in a certain position along the directions of depth, length, height, and the like (including without limitation), automatically, semi-automatically, and automatically (including without limitation).
Further, in this embodiment, the method further includes step S107: the debugging order of step S102 is updated according to the debugging order and performance and change information of step S105 and step S106. In this implementation, the debugging sequence is updated by artificial intelligence, the control device repeats the steps S105 and S106, after completing the artificial intelligence automatic debugging process of a certain number of adjusting screws, the real-time testing results of the performance changes of the corresponding cavity filter are accumulated, the artificial intelligence analysis is performed on the debugging process of all performance indexes of the cavity filter, such as VSWR, insertion loss, flatness, isolation, and the like, the target experience is determined, the debugging sequence is updated accordingly, the subsequent artificial intelligence debugging is controlled, and the debugging is performed according to the updated debugging sequence, so that the debugging quality and efficiency are further improved. In this embodiment, an artificial intelligence automatic mode is adopted to update and change the debugging sequence, but in other embodiments, the debugging sequence can also be updated and changed through a template, a die, a tool, a clamp and the like (including but not limited to), automatically, semi-automatically and manually (including but not limited to).
Further, in this implementation, the steps S105, S106, and S107 are repeated until the feedback performance parameters of the network analyzer completely meet the requirements, the performance of the cavity filter reaches the standard, and the artificial intelligence automatic debugging is completed. However, if the artificial intelligence pre-debugging in step S105 is abnormal, the artificial intelligence debugging sequence in step S107 is abnormal, and the performance and variation of the cavity filter are monitored in real time by the industrial control, the debugging is determined to be abnormal, and the subsequent abnormal processing is performed.
After debugging of all adjusting screws is completed, all parameters, process and performance results and changes of artificial intelligence debugging of all cavity filters are recorded, machine learning and artificial intelligence processing are carried out, an artificial intelligence debugging mode for debugging cavity filters in batches of the same model is gradually formed, the debugging process is simplified, and the artificial intelligence debugging efficiency is further improved.

It will be appreciated that the number of first axial slots 91, first guides, and openings may be one or more as desired. The first guide piece can be a positioning screw, a bolt, a guide column and the like, and the guide self-positioning sleeve 9 can be axially and slidably connected to the screwdriver connecting sleeve 8.
Further, for better guiding the screw, the inner side of the lower end of the guiding self-positioning sleeve 9 is an inner inclined surface, in this embodiment, the inner inclined surface is processed to be 45 degrees, and of course, the inclined angle can be designed to be other degrees according to the requirement.
Because the port plane position of the guide self-positioning sleeve 9 is greater than the port position at the bottom of the screwdriver 6, the inner side of the hollow cylinder at the lower end of the guide self-positioning sleeve 9 is ensured to be contacted with the adjusting screw 31 at first in the process of moving downwards along the axial direction to approach the adjusting screw 31, and due to the guide self-positioning characteristic of the inner inclined plane, the deviation between the actual operation center position of the adjusting screw 31 and the center position of the identified screw hole can be automatically compensated, and the position deviation tolerance capability is good. When the screwdriver 6 is moved downward in the axial direction to contact the adjusting screw 31 after the basic correction position deviation of the screwdriver 6 in the guiding and positioning sleeve is achieved, and the screwdriver is moved to a certain position, the screw rotating driving device 1 rotates the screwdriver 6 at a slow speed, and the screwdriver 6 can be inserted into the adjusting screw 31 quickly and reliably, so that the automatic adjustment is ready.
In addition, since the adjusting screw 31 is connected with the fixing nut 32, the upper end surface of the adjusting screw 31 may be lower than the upper end surface of the fixing nut 32, and since the guiding and positioning sleeve can move up and down along the axial direction, the upper end surface of the adjusting screw 31 can be quickly and reliably rotated into the lower part of the upper end surface of the fixing nut 32.
Further, in this embodiment, the debugging unit further includes a nut-and-socket actuator, which can automatically rotate the nut to loosen or tighten the nut. Of course, in other embodiments, the nut-socket actuator may be omitted.
As shown, the nut-socket actuator includes a nut-socket drive 11, a transmission mechanism, a screwdriver spindle outer sleeve 20, a nut-socket assembly, and the like.
The nut socket driving device 11 is a second servo driving motor which is horizontally and fixedly installed, and can be fixedly installed on the sliding block 22 through the installation seat 13, and further can move up and down to drive the whole nut socket actuating mechanism to move up and down. Of course, it may be mounted at other suitable locations as desired. The output shaft of the second servo drive motor transmits the rotating torque to the screwdriver spindle outer sleeve 20 through the transmission mechanism, so that the screwdriver spindle outer sleeve 20 can rotate around the axis of the screwdriver spindle outer sleeve to drive the nut sleeve assembly to rotate around the axis of the screwdriver spindle outer sleeve, and the forward and reverse rotation control of the nut is realized. Of course, the nut-socket driving device 11 may be other driving mechanisms, such as an air cylinder, a stepping motor, and the like.
The nut socket drive 11 outputs a rotational torque via a transmission mechanism including a worm 14, a worm wheel 15, a transmission intermediate shaft 16, a spur gear set 19, and the like. The worm 14 is mounted on the output shaft of the second servo drive motor, drives the worm wheel 15 to rotate, then drives the transmission intermediate shaft 16 to rotate by the worm wheel 15, and then drives the screwdriver spindle outer sleeve 20 to rotate by the spur gear set 19.
In the present embodiment, the intermediate transmission shaft 16 is disposed parallel to the axial direction of the driver 6, and can be fastened and mounted to the mount base 13 by an angular contact ball bearing 17, a locknut 18, and the like. A pair of spur gears are fixedly arranged on the transmission intermediate shaft 16 and the screwdriver spindle outer sleeve 20 respectively, and the transmission of the worm wheel 15, the worm 14 and the spur gears is utilized, so that the torsional moment can be transmitted more stably and reliably, and the rotation is more stable. It will be appreciated that the transmission mechanism may be implemented by other mechanisms, such as various structures including rack and pinion, gear belt, etc., as long as the torque output from the nut socket driving device 11 can be smoothly transmitted to the screwdriver spindle outer sleeve 20.
The screwdriver spindle outer sleeve 20 is rotatably sleeved outside the screwdriver component and is arranged coaxially with the screwdriver spindle 5. The screwdriver spindle outer sleeve 20 can also be fastened and mounted on the mounting seat 13 through the angular contact ball bearing 17 and the locknut 18, so that the torsional moment of the nut sleeve driving device 11 can be stably and reliably transmitted to the screwdriver spindle outer sleeve 20 concentric with the screwdriver spindle 5, and the nut sleeve assembly is driven to rotate.
The nut sleeve assembly is coaxially arranged with the screwdriver spindle outer sleeve 20 and is axially slidably mounted on the lower end of the screwdriver spindle outer sleeve 20. In this embodiment, the nut-sleeve assembly includes a nut outer sleeve 23, and a nut sleeve 24 fixedly mounted on the lower end of the nut outer sleeve 23. Of course, the nut outer sleeve 23 and the nut sleeve 24 can also be of one-piece design. The size and shape of the nut socket 24 can be changed according to the nut to be handled.
Further, a second axial slot 231 can be formed on the outer sleeve of the nut sleeve 24; in the present embodiment, as shown in FIG. 10, the second axial slots 231 are four axially aligned uniform slots provided in the upper portion of the outer sleeve of the nut sleeve 24. Correspondingly, the screwdriver spindle outer sleeve 20 is provided with four holes, and the nut sleeve 24 can be axially movably mounted on the screwdriver spindle outer sleeve 20 by inserting the four second guiding members into the second axial slot 231 and the holes respectively, so that the nut sleeve 24 can rotate along with the screwdriver spindle outer sleeve 20 and can also move up and down on the screwdriver spindle outer sleeve 20 along the axial direction. It is understood that the number of the second axial slot 231, the second guide member, and the opening may be one or more as desired. The second guiding member may be a set screw, a bolt, a guiding column, etc. and it is sufficient to axially slidably connect the outer sleeve of the nut sleeve 24 to the outer sleeve 20 of the screwdriver spindle.
Further, a second spring 25 is provided between the top end of the nut outer sleeve 23 and the screwdriver spindle outer sleeve 20, and ensures that the nut sleeve 24 is moved up and down in the axial direction on the screwdriver spindle outer sleeve 20. Since the nut socket 24 is securely connected to the nut socket driving device 11 and is concentric with the screwdriver spindle 5, and can move up and down in the axial direction, the fastening, tightening, and torque control of the fixing nut 32 can be stably and securely performed.
Further, the inner side of the lower end of the nut sleeve 24 is processed into an inner inclined surface, which is 45 degrees (of course, the inclination degree can be designed as required) in the embodiment, after the inner inclined surface moves downward along the axial direction to contact the fixing nut 32, due to the guiding self-positioning characteristic of the inner inclined surface, the deviation between the actual operation center position of the fixing nut 32 and the center position of the identified screw hole can be automatically compensated, and the nut sleeve driving device 11 rotates at a slower speed, so that the fixing nut 32 can be quickly and reliably sleeved by the nut sleeve 24, and preparation is made for automatic operations such as loosening of the fixing nut 32, fastening, torque control and the like.
Further, in order to ensure that the screwdriver 6 of the screw rotation automatic debugging mechanism passes through the center of the nut sleeve 24, the coaxiality of the screw rotation automatic debugging mechanism and the nut sleeve executing mechanism needs to be ensured. In the embodiment, the outer sleeve 20 of the screwdriver spindle in the nut sleeve actuating mechanism is tightly fixed through the angular contact ball bearing 17 and the locknut 18, so that the coaxiality of the outer sleeve and the screwdriver spindle 5 can be basically ensured; the nut sleeve 24 connected through the outer sleeve of the nut sleeve 24 is a cantilever structure, and in order to ensure the coaxiality with the screwdriver 6, deep groove ball bearings 26 are respectively arranged between the screwdriver main shaft 5 and the outer sleeve 20 of the screwdriver main shaft and between the guide positioning sleeve of the screwdriver 6 and the outer sleeve of the nut sleeve 24, so as to ensure the coaxiality of the screwdriver main shaft 5 and the outer sleeve 20 of the screwdriver main shaft and the outer sleeve of the screwdriver 6 guide positioning sleeve and the nut sleeve 24, ensure the coaxiality of the screwdriver 6 passing through the center of the nut sleeve 24, and ensure the coaxiality of the screw rotation automatic debugging mechanism and the nut sleeve execution mechanism.
The screw rotation automatic debugging mechanism and the nut sleeve actuating mechanism are compact in structure, can be used for an automatic debugging machine table, stably and reliably achieve high-speed rotation of forward and reverse rotation of a screw, torque control and accurate positioning, and functions of loosening, fastening and torque control of the fixing nut 32.

The debugging unit may be a debugging unit with any combination of the above structures, which is not described herein. It can be understood that this automatic debugging board can be used for the regulation of cavity filter 30's screw, nut to debug whole cavity filter 30's band-pass curve, with the defect that the uniformity of solving artifical regulation is low, inefficiency.
As shown in the figure, the platform 3 is disposed parallel to the axis direction of the screwdriver component of the debugging unit, and serves as a support for the whole machine. It will be appreciated that the platform 3 may be mounted on an X-axis drive unit 106 and may be moved in the X, Y and Z axes to adjust the position of the platform 3 to align the commissioning unit with the screws, nuts etc. to be adjusted.
The guide rail base 21 is fixedly arranged on the platform 3 in parallel and is parallel to the axis of the screwdriver component; correspondingly, the slide block 22 is slidably mounted on the guide rail base 21, and the debugging unit is mounted on the slide block 22, so that the debugging unit can move up and down under the guidance of the guide rail base 21.
In this embodiment, the screw rotation driving device 1 of the automatic adjustment mechanism is fixedly mounted on the first bracket 27, and the first bracket 27 is fixedly mounted on the slider 22, so that the entire screw adjustment unit is fixedly mounted on the slider 22.
Further, the automatic debugging machine also comprises a mounting seat 13 vertically and fixedly mounted on the sliding block 22. The nut socket driving device 11 of the automatic debugging mechanism is fixedly arranged on the second bracket 12 and is fixedly arranged on the mounting seat 13 through the second bracket 12. The axial direction of the output shaft of the nut socket drive device 11 is perpendicular to the axial direction of the output shaft of the screw rotation drive device 1.
Furthermore, the transmission intermediate shaft 16 and the screwdriver spindle outer sleeve 20 of the automatic debugging mechanism are tightly mounted on the mounting seat 13 through the angular contact ball bearing 17 and the locknut 18, so that the coaxiality of the automatic debugging mechanism and the screwdriver spindle 5 can be basically ensured, and the stability and reliability of rotation are ensured.
When the automatic debugging machine is used for debugging screws, engineering design file import or real-time optical position recognition screw hole center position is generally adopted as the center position of the adjusting screw 31, and the platform 3 is driven by the three-axis driving device to reach the center position of the screw 31 to be adjusted. The central position and the actual operation central position of the automatic debugging of the adjusting screw 31 may have larger deviation, if the operation is carried out only by the identified screw hole central position, the adjusting screw 31 may not be reliably and effectively inserted, which causes abnormal operation, at this time, the downward moving slide block 22 drives the screw debugging unit to move downward, the lower end of the guiding self-positioning sleeve 9 contacts the screw first, and under the action of the inner inclined surface, the deviation between the actual operation central position of the adjusting screw 31 and the identified screw hole central position can be automatically compensated; then, moving down a further distance, the screw rotation drive 1 rotates the screw driver 6 at a slower speed, and the screw driver 6 can be inserted into the adjusting screw 31 quickly and reliably, ready for automatic adjustment.
In addition, since the adjusting screw 31 is connected with the fixing nut 32, the upper end surface of the adjusting screw 31 may be lower than the upper end surface of the fixing nut 32, and since the guiding self-positioning sleeve 9 can move up and down along the axial direction, the upper end surface of the adjusting screw 31 can be quickly and reliably rotated into the lower part of the upper end surface of the fixing nut 32.
When the automatic debugging machine is used for nut loosening, fastening and torque control, engineering design file import or real-time optical position recognition screw hole center position is generally adopted as the center position of the fixed nut 32, but the center position and the actual operation center position of the fixed nut 32 may have larger deviation, and the fixed nut 32 may not be reliably and effectively sleeved by the nut sleeve 24, so that the phenomenon of rotation and slippage is caused. In the embodiment, the slide block 22 is moved downwards to drive the nut-sleeve actuating mechanism to move downwards, the lower end of the nut sleeve 24 contacts with the screw first, and under the action of the inner inclined surface, the deviation between the actual operation center position of the fixed nut 32 and the center position of the identified screw hole can be compensated and adjusted automatically; then, continuing to move downward in the axial direction for a certain amount of time, the nut-socket drive 11 rotates at a slower speed, and the nut socket 24 can be quickly and reliably received over the fastening nut 32, providing for automatic operation of loosening, tightening, torque control, etc. of the fastening nut 32.
