Description

Technical Field

[0001] The present invention relates to the technical field of dielectric filters, and in particular to an automatic debugging method, device and system for dielectric filters. Background Art

[0002] As an indispensable frequency selection device, the filter is a key device in modern mobile communication systems and a core device for wireless communication base stations and signal coverage. The performance of the filter directly affects the quality of the entire system. Dielectric filters have excellent performances such as high stopband suppression, wide bandwidth, flat passband, small group delay and narrow transition band, and have been widely used in modern mobile communication systems.

[0003] like Figure 1 As shown, the basic structure of the dielectric filter is that there are a series of resonant / coupling holes and resonant / coupling gaps on the dielectric body (usually a ceramic body), and the surface of the dielectric body is fully or partially covered with conductive materials such as silver paste. The conductive materials such as silver paste at the bottom and / or inner wall of the resonant / coupling hole are removed, thereby changing the corresponding equivalent capacitance and equivalent inductance values, thereby adjusting the performance indicators of the dielectric filter. This is the performance debugging process of the dielectric filter. Due to the high performance requirements of the dielectric filter, the removal amount of conductive materials such as silver paste at the bottom and / or inner wall of the resonant / coupling hole is very sensitive, and the number of resonant / coupling holes is large, so the debugging of the dielectric filter is very difficult and complicated.

[0004] For a long time, the debugging of dielectric filters has basically been done manually by experienced workers. The dielectric filter is connected to a network analyzer. The experienced worker uses an electric tool to rotate the grinding head, which is inserted into the resonance / coupling hole to remove the silver paste and other conductive materials at the bottom and / or inner wall of the hole. The network analyzer monitors the performance changes of the dielectric filter in real time. The experienced worker completely follows the proficiency of the work and the accumulation of actual operation experience. According to the performance changes of the dielectric filter, the experienced worker repeatedly tries multiple groups of combinations of the amount of silver paste and other conductive materials removed from the bottom and / or inner wall of the resonance / coupling hole, and finally achieves the performance of the dielectric filter. Therefore, the debugging of the dielectric filter is complex and arduous. Only fully trained experienced workers can complete the complex debugging of the dielectric filter and achieve the performance of the dielectric filter. In addition, in the actual mass production of dielectric filters, due to the influence of error factors such as production and assembly, each dielectric filter must be fully debugged by skilled workers to achieve performance consistency and stability. This brings huge production costs and production capacity bottlenecks, which has always been a huge obstacle to the scale and industrial development of dielectric filters. Summary of the invention

[0051] For a clearer understanding of the technical features, objectives, and effects of the present invention, the specific embodiments of the present invention will now be described in detail with reference to the drawings.

Therefore, it should not be construed as a limitation to the present invention.

[0053] The first embodiment, as Figure 2 shown, Figure 2 is a schematic structural diagram of the automatic debugging device for the dielectric filter of the present invention. The present invention constructs an automatic debugging device for a dielectric filter. Among them, the dielectric filter includes a dielectric body, and a plurality of resonant holes are provided on the dielectric body, and all or part of the surface of the dielectric body is covered with a conductive substance. In this embodiment, the conductive substance is silver paste. The automatic debugging device for the dielectric filter includes: at least one removing unit 2 for removing the conductive substance on the surface of the resonant hole, and a servo driving device 4 connected to the removing unit 2 for driving the removing unit 2 to move.

[0054] The automatic debugging device for the dielectric filter further includes: a debugging platform 1 for fixing the dielectric filter. Specifically, a machine platform 11 is provided on the debugging platform 1, and the dielectric filter is fixed on the machine platform 11.

[0055] The automatic debugging device for the dielectric filter further includes: a control device 3 installed on the debugging platform 1. The servo driving device 4 is installed on a bracket, and the control device 3 is connected and fixed to the bracket. The control device 3 drives the servo driving device 4 to move through the bracket, so as to drive the removing unit 2 to be positioned at the position of the resonant hole, and the control device 3 drives the removing unit 2 to perform axial or radial movement in the resonant hole by controlling the servo driving device 4. In this embodiment, the control device 3 is an X / Y / Z space position positioning coordinate machine platform or a robotic arm.

[0056] The servo driving device 4 is used to drive the removing unit 2 to move in three axial directions, so that the removing unit 2 performs axial or radial movement in the resonant hole. It includes: at least one Y-axis driving unit 42, and an X-axis driving unit 41 and a Z-axis driving unit 43 corresponding to the number of removing units 2. The removing unit 2 is connected to the Z-axis driving unit 43. For example, when this embodiment is multi-axis debugging, when the number of rows of resonant holes in the dielectric filter in the Y-axis direction is two rows, the Y-axis driving unit 42 is two, which are respectively located on both sides of the dielectric filter. When the removing unit 2 is also two, the X-axis driving unit 41 and the Z-axis driving unit 43 are also two.

[0057] Specifically, the Y-axis driving unit 42 is fixed on the bracket, the X-axis driving unit 41 is installed on the Y-axis driving unit 42, and the Y-axis driving unit 42 drives the X-axis driving unit 41 to move back and forth in the Y-axis direction. The Z-axis driving unit 43 is installed on the X-axis driving unit 41, and the X-axis driving unit 41 drives the Z-axis driving unit 43 to move back and forth in the X-axis direction. It can be understood that the X-axis driving unit 41, the Y-axis driving unit 42, and the Z-axis driving unit 43 can all include sliders, slide rails, etc.

[0058] The automatic debugging of the dielectric filter must also precisely control the grinding force of the grinding head unit 21 to ensure good debugging effects. Therefore, a pressure sensor 44 is provided on each Z-axis drive unit 43. Through the precision pressure sensor 44, precise control of the grinding force of the grinding head unit 21 is achieved, ensuring the stability of the automatic debugging of the dielectric filter.

[0059] The removing unit 2 moves axially and / or radially within the resonant hole to remove the conductive material on the bottom layer and / or side wall of the resonant hole. As Figure 3 shown, Figure 3 is a schematic structural diagram of the removing unit of the present invention, which includes: a grinding head unit 21 for contacting the conductive material on the bottom and / or side wall of the resonant hole, a flexible shaft unit 22 detachably or fixedly connected to the grinding head unit 21, a torque generator 25 connected to the flexible shaft unit 22 for transmitting torque to the grinding head unit 21 through the flexible shaft unit 22, and a bearing bracket 23 connected to the servo drive device 4 for supporting the rotation of the grinding head unit 21.

[0060] Among them, the grinding head unit 21 includes: a transmission shaft 211 and a grinding head 212 fixedly connected. The transmission shaft 211 is detachably or fixedly connected to the flexible shaft unit 22, and the grinding head 212 contacts the conductive material on the bottom and / or side wall of the resonant hole.

[0061] The bearing bracket 23 includes: at least two bearings 231 for sleeving on the transmission shaft 211, and a bracket 232 connecting and fixing the bearings 231 and the servo drive device 4.

[0062] In this embodiment, the upper part of the transmission shaft 211 is detachably or fixedly connected to the flexible shaft unit 22, and the lower part of the transmission shaft 211 is fixedly connected to the grinding head 212. Since the lower part of the transmission shaft 211 and the grinding head 212 are used to extend into the resonant hole, the total length of the lower part of the transmission shaft 211 and the grinding head 212 should be greater than or equal to the depth of the resonant hole. Preferably, the grinding head 212 is a hemispherical grinding head, and its spherical diameter is larger than the diameter of the lower part of the transmission shaft 211. The hemispherical grinding head moves axially to the bottom of the resonant hole, and the bottom of the hemispherical grinding head contacts the bottom of the resonant hole, thereby reliably removing the silver paste conductive layer at the bottom of the resonant / coupling hole. The hemispherical grinding head moves radially to the inner side wall of the resonant hole, and the side part of the hemispherical grinding head contacts the inner side wall of the resonant hole, thereby reliably removing the silver paste conductive layer on the inner side wall of the resonant / coupling hole. In other embodiments, the grinding head 212 can be in the shape of an elliptical grinding head, etc., which will not be elaborated here.

[0063] In this embodiment, preferably two bearings 231 are respectively sleeved on both ends of the middle part of the transmission shaft 211. Since there is no concentricity when the flexible shaft unit 22 rotates, it is necessary to use double bearings 231 to ensure the concentricity of the transmission shaft 211. The bracket 232 is used to fix the position of the bearing 231, thereby fixing the removing unit 2 on the servo drive device 4.

[0064] Moreover, the removing unit 2 further includes: a coupling 24. The transmission shaft 211 and the flexible shaft unit 22 are respectively inserted into the coupling 24 and are tightly fitted and fixed to the coupling 24. And in this embodiment, a plurality of screw holes are provided on the side wall of the coupling 24 for fixing the transmission shaft 211 and the flexible shaft unit 22 on the coupling 24 by screws.

[0065] The torque generator 25 is an electric screwdriver in this embodiment and is fixedly installed on the debugging platform 1. Figure 2 Only the connection between the flexible shaft at one electric screwdriver end and the flexible shaft at one removing unit 2 end is shown here. It should be noted that the flexible shafts at other electric screwdriver ends and the flexible shafts at other removing unit 2 ends are also connected to each other in this way, and the flexible shafts do not affect each other.

[0066] Preferably, in this embodiment, there are at least two removing units 2, which respectively correspond to at least two resonant holes. Correspondingly, the X-axis driving unit 41, the Z-axis driving unit 43 and the pressure sensor 44 are all at least two and are respectively installed on at least one Y-axis driving unit 42. Since the mutual spacing of the corresponding resonant / coupling holes of the dielectric filter is relatively small, the mutual spacing of the grinding head units 21 of the automatic debugging device is also relatively small. The traditional direct installation method of the electric screwdriver cannot be adopted. Instead, the flexible shaft unit 22 is used to connect the electric screwdriver and the grinding head unit 21 to ensure that the minimum mutual spacing of the grinding head units 21 of the automatic debugging device is 10 mm, and the mutual spacing of the grinding head units can be precisely adjusted by each set of servo drive devices 4 to be completely consistent with the corresponding resonant / coupling hole positions of the dielectric filter, so as to realize the multi-axis automatic debugging of all resonant / coupling holes.

[0067] In other embodiments, there may be one removing unit 2. Correspondingly, the X-axis driving unit 41, the Y-axis driving unit 42, the Z-axis driving unit 43 and the pressure sensor 44 are all one. The removing unit 2 may include the above structure, or the electric screwdriver may be directly connected through the servo drive device 4, and the grinding head unit is driven to rotate by the electric screwdriver to sequentially remove conductive substances such as silver paste from the inner bottom and / or side wall of each resonant / coupling hole of the dielectric filter.

[0068] Multi-axis automatic debugging of a dielectric filter is provided with a removal unit 2 that is consistent with the number of resonant / coupling holes to be debugged in the dielectric filter. Each removal unit 2 includes a grinding head unit 21, which is connected to an electric screwdriver through a flexible shaft unit 22 or an optical fiber. Each removal unit 2 is fixedly connected to an independent two-axis precision position servo and precision pressure servo device, namely an X-axis drive unit 41, a Z-axis drive unit 43, and a pressure sensor 44, to achieve position matching with the corresponding resonant / coupling hole positions, and to remove the silver paste conductive material at the bottom and / or side walls inside the resonant / coupling holes. Under the control of the control device 3, automatic debugging of all the resonant / coupling holes of the dielectric filter is carried out simultaneously to ensure extremely high efficiency, as well as excellent stability and reliability.

[0069] In the second embodiment, the present invention constructs an automatic debugging device for a dielectric filter. Among them, the dielectric filter includes a dielectric body, on which a plurality of resonant holes are provided, and all or part of the surface of the dielectric body is covered with a conductive material. In this embodiment, the conductive material is silver paste. The automatic debugging device for the dielectric filter includes: at least one removal unit 2 for removing the conductive material on the surface of the resonant hole, and a servo drive device 4 connected to the removal unit 2 for driving the removal unit 2 to move.

[0070] The automatic debugging device for the dielectric filter further includes: a debugging platform 1 for fixing the dielectric filter. Specifically, a machine platform 11 is provided on the debugging platform 1, and the dielectric filter is fixed on the machine platform 11.

[0071] The automatic debugging device for the dielectric filter further includes: a control device 3 installed on the debugging platform 1. The servo drive device 4 is installed on a bracket, and the control device 3 is connected and fixed to the bracket. The control device 3 drives the servo drive device 4 to move through the bracket, so as to drive the removal unit 2 to be positioned at the position of the resonant hole, and the control device 3 drives the removal unit 2 to perform axial or radial movement inside the resonant hole by controlling the servo drive device 4. In this embodiment, the control device 3 is an X / Y / Z space position positioning coordinate machine platform or a robotic arm.

[0072] The servo drive device 4 is used to drive the removal unit 2 to move in three-axis directions, so that the removal unit 2 performs axial or radial movement inside the resonant hole. It includes: at least one Y-axis drive unit 42, and an X-axis drive unit 41 and a Z-axis drive unit 43 corresponding to the number of removal units 2. The removal unit 2 is connected to the Z-axis drive unit 43. For example, when this embodiment is multi-axis debugging, when the number of rows of resonant holes in the dielectric filter in the Y-axis direction is two rows, the Y-axis drive unit 42 is two, which are respectively located on both sides of the dielectric filter. When the number of removal units 2 is also two, the X-axis drive unit 41 and the Z-axis drive unit 43 are also two.

[0073] Specifically, the Y-axis driving unit 42 is fixed on the bracket, the X-axis driving unit 41 is installed on the Y-axis driving unit 42, and the Y-axis driving unit 42 drives the X-axis driving unit 41 to move back and forth in the Y-axis direction. The Z-axis driving unit 43 is installed on the X-axis driving unit 41, and the X-axis driving unit 41 drives the Z-axis driving unit 43 to move back and forth in the X-axis direction. It can be understood that the X-axis driving unit 41, the Y-axis driving unit 42, and the Z-axis driving unit 43 can all include sliders, slide rails, etc.

[0074] The removing unit 2 performs axial and / or radial movement in the resonant hole to remove the conductive substances on the bottom layer and / or side wall in the resonant hole. The removing unit 2 includes: a laser head assembly. The control device 3 is also connected to the laser head assembly for controlling the steering of the laser head assembly, and removing the conductive substances on the bottom layer and / or side wall in the resonant hole by laser.

[0075] The laser head assembly includes: a fixed shaft, a steering assembly, and a laser source connected in sequence. The fixed shaft is detachably connected or fixedly connected to the servo driving device 4. The control device 3 is respectively connected to the steering assembly and the laser source to control the turning on or off of the laser source, and drive the laser source to perform circular arc movement in the resonant hole by controlling the steering assembly to remove the conductive substances on the bottom and / or side wall of the resonant hole. Moreover, the control device 3 also drives the laser head assembly to move in the resonant hole through the servo driving device 4 to further adjust the position of the laser. In this embodiment, the fixed shaft can be an optical fiber, and the laser source is a high-power laser source.

[0076] Preferably, in this embodiment, the removing unit 2 includes at least two, corresponding to at least two resonant holes respectively. Correspondingly, both the X-axis driving unit 41 and the Z-axis driving unit 43 are at least two, and are respectively installed on at least one Y-axis driving unit 42. In other embodiments, the removing unit 2 can be one. Correspondingly, the X-axis driving unit 41, the Y-axis driving unit 42, and the Z-axis driving unit 43 are all one, and the silver paste and other conductive substances at the bottom and / or side wall of each resonant / coupling hole of the dielectric filter are removed by laser in sequence.

[0077] For the multi-axis automatic debugging of the dielectric filter, there are removing units 2 with the same number as the number of resonant / coupling holes to be debugged of the dielectric filter. Each removing unit 2 includes a laser head assembly. Each removing unit 2 is fixedly connected to an independent two-axis precision position servo device, that is, the X-axis driving unit 41 and the Z-axis driving unit 43, to achieve the position matching with the corresponding resonant / coupling hole positions, and the laser removal of the silver paste conductive substances at the bottom and / or side wall in the resonant / coupling holes. Under the control of the control device 3, the laser automatic debugging of all resonant / coupling holes of the dielectric filter is carried out simultaneously to ensure extremely high efficiency, as well as excellent stability and reliability.

[0078] The third embodiment is as Figure 4As shown Figure 4 is a schematic diagram of the automatic debugging system for the dielectric filter of the present invention. The present invention constructs an automatic debugging system for the dielectric filter. Among them, the dielectric filter includes a dielectric body, and a plurality of resonant holes are provided on the dielectric body, and the surface of the dielectric body is entirely or partially covered with a conductive material, including:

[0079] A network analyzer 6 for reading the real-time monitored performance of the dielectric filter;

[0080] An industrial control computer 5 for comparing the real-time monitored performance read by the network analyzer 6 with the target performance to generate a control signal;

[0081] The automatic debugging device for the dielectric filter is used to remove the conductive material on the surface of the resonant hole through at least one removing unit 2 according to the control signal of the industrial control computer 5 until the real-time monitored performance read by the network analyzer 6 matches the target performance.

[0082] Among them, the automatic debugging device for the dielectric filter in this embodiment is the automatic debugging device for the dielectric filter in the above first embodiment and second embodiment, which will not be elaborated here.

[0083] Specifically, the control device 3 is connected to the industrial control computer 5. The control device 3 is fixed on the debugging platform 1. A servo drive device 4 and a removing unit 2 are installed on the control device 3. The dielectric filter is fixed on the machine platform 11 and connected to the network analyzer 6 to monitor the performance of the dielectric filter in real time. The industrial control computer 5 is also connected to the network analyzer 6 to read the real-time monitored performance of the dielectric filter, compare the real-time monitored performance with the target performance, and issue an automatic control command to the control device 3 to drive the removing unit 2 into the corresponding resonant / coupling hole through the servo drive device 4 to remove the conductive material such as silver paste on the bottom and / or inner side wall. Since this dielectric filter has a total of 6 resonant / coupling holes, it is a six-axis automatic debugging device. At the same time, under the automatic control of the industrial control computer 5, the corresponding resonant / coupling holes are automatically operated. Finally, the industrial control computer 5 reads the real-time performance from the network analyzer 6 to match the target performance, and completes the automatic debugging of the dielectric filter.

[0084] The fourth embodiment, as Figure 5 shown Figure 5 is a flowchart of the automatic debugging method for the dielectric filter of the present invention. On the basis of the above system, the present invention constructs an automatic debugging method for the dielectric filter. Among them, the dielectric filter includes a dielectric body, and a plurality of resonant holes are provided on the dielectric body, and the surface of the dielectric body is entirely or partially covered with a conductive material. The method includes the following steps:

[0085] S1: Read the real-time monitored performance of the dielectric filter through the network analyzer 6;

[0086] S2: Compare the real-time monitoring performance with the target performance to generate a control signal. Among them, the target performance can be input into the industrial control computer 5, and the generated control signal includes the set removal amount of the conductive substance.

[0087] S3: According to the control signal, through at least one removal unit 2, remove the conductive substance on the surface of the resonant holes.

[0088] Repeat the above steps S1 - S3 until the real-time monitoring performance matches the target performance.

[0089] Specifically, in step S3, it includes:

[0092] S3 - 3: The removal unit 2 removes the corresponding amount of conductive substance in its corresponding resonant hole according to the set removal amount of the conductive substance in the control signal. Among them, the removal unit 2 moves axially and / or radially in the resonant hole to remove the conductive substance at the bottom layer and / or the side wall in the resonant hole.

[0094] The torque generator 25 transmits torque to at least two grinding head units 21 through the flexible shaft unit 22 respectively, and drives at least two grinding head units 21 on the bearing bracket 23 to move axially and / or radially in the resonant hole through the servo drive device 4, contact the conductive substance at the bottom layer and / or the side wall in the resonant hole, and remove the conductive substance at the bottom layer and / or the side wall in the resonant hole.

[0095] And / or, drive at least two laser head assemblies to move axially and / or radially in the resonant hole through the servo drive device 4, and control the steering of at least two laser head assemblies through the control device 3 to remove the conductive substance at the bottom layer and / or the side wall in the resonant hole by laser.

[0096] By implementing the present invention, the following beneficial effects are achieved:

[0097] The present invention reads the real-time monitoring performance of the dielectric filter through a network analyzer, compares the real-time monitoring performance with the target performance to generate a control signal, and according to the control signal, through at least one removal unit, removes the conductive substance on the surface of the resonant holes until the real-time monitoring performance matches the target performance, which can greatly reduce the production cost and improve the production capacity, fully meeting the requirements of large-scale and industrial production of actual dielectric filters.

[0098] Moreover, the present invention designs at least two removal units. The torque generator is connected to the grinding head unit through a flexible shaft, and the mutual distance between the grinding head units can be precisely adjusted through each set of servo drive devices, ensuring that the distance between the grinding head units is small enough to be completely consistent with the corresponding resonance / coupling hole positions of the dielectric filter. Then, according to the control signal, the servo drive device drives the grinding head unit to perform axial and / or radial movement in the resonance / coupling hole to remove the conductive substances on the bottom layer and / or side wall in the resonance hole, thereby realizing the multi-axis automatic debugging of the dielectric filter.
