Description

Technical Field

[0001] The present invention relates to the technical field of electronic product welding devices, and specifically to a microwave component welding device and its welding method. Background Art

[0002] Microwave components are widely used in modern communication, radar, aerospace and other fields, and their performance directly affects the working effect of the entire system. Welding, as a key process in the manufacturing process of microwave components, plays a decisive role in the electrical performance, mechanical performance and reliability of the components. Traditional microwave component welding methods mainly include manual welding, wave soldering, reflow soldering, etc. With the continuous development of microwave technology, the structure of microwave components is becoming more and more complex, and the requirements for welding accuracy, quality and efficiency are also getting higher and higher. Traditional welding methods are gradually difficult to meet the actual needs.

[0003] Currently, the movement trajectory of traditional welding equipment is relatively fixed, making it difficult to meet the welding requirements of microwave components with complex shapes, resulting in large welding position deviations, affecting the electrical performance of the components. Moreover, the heat generated during the welding process will cause thermal stress in the components, leading to component deformation, cracking, reducing the reliability and service life of the components. At the same time, manual welding is slow, labor-intensive, and the quality is unstable. Although automated welding methods such as wave soldering and reflow soldering are relatively efficient, for some microwave components with special structures, there are still problems such as difficult welding and low efficiency. Therefore, it is necessary to propose a microwave component welding device and its welding method. Summary of the Invention

[0004] The purpose of the present invention is to provide a microwave component welding device and its welding method to solve the problems raised in the above background art, that is, the movement trajectory of traditional welding equipment is relatively fixed, making it difficult to meet the welding requirements of microwave components with complex shapes, resulting in large welding position deviations, affecting the electrical performance of the components. Moreover, the heat generated during the welding process will cause thermal stress in the components, leading to component deformation, cracking, reducing the reliability and service life of the components. At the same time, manual welding is slow, labor-intensive, and the quality is unstable. Although automated welding methods such as wave soldering and reflow soldering are relatively efficient, for some microwave components with special structures, there are still problems such as difficult welding and low efficiency.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A microwave component welding device, comprising an operation base, four groups of stabilizing components, an adaptive welding component and a microwave component structure:

[0006] Four groups of the stabilizing components are installed at the four ends of the operation base. After the microwave component structure undergoes pre-treatment processes such as cleaning, drying, surface treatment, and installation, it is embedded and installed inside the central groove of the operation base through an external manipulator. The four groups of the stabilizing components are used to press and stabilize the solder joint structures to be welded inside the placed microwave component structure;

[0007] Two groups of transverse short-path guide rails are symmetrically installed on the surface of the operation base. A semi-circular arc guide rail is slidably connected inside the two groups of transverse short-path guide rails. The adaptive welding component is slidably connected inside the semi-circular arc guide rail. The adaptive welding component is used to be able to approach the microwave component structure from different angles for all-round and high-precision welding operations;

[0008] The adaptive welding component includes a trolley seat. A nut roller is installed inside the trolley seat. A connecting frame is installed on the frame surface of the trolley seat. A rotating motor seat is installed on the top of the connecting frame. An angle rotation adjustment seat is installed at the top of the rotating motor seat. An adjustment driving arm is rotatably connected inside the angle rotation adjustment seat. A welding installation seat is installed at the side end of the adjustment driving arm. The welding installation seat is used to install a laser control emitter or other welding devices. During the welding process, the welding installation seat drives the welding device to perform real-time imaging of the welding part by using an external optical coherence tomography scanner.

[0009] Preferably, each trolley seat is equipped with a high-precision visual recognition unit. The high-precision visual recognition unit includes at least three high-definition cameras distributed at different angles and a supporting image analysis and processing chip. During the movement of the trolley seat along the semi-circular arc guide rail, the high-definition cameras continuously capture images of the welding parts of the microwave component structure. The image analysis and processing chip analyzes the image data in real time to identify the precise position, size, surface condition, and relative position relationship with the surrounding structure of the welding points, and feeds the analysis results back to the built-in PLC controller of the trolley seat.

[0010] Preferably, the semi-circular arc guide rail adopts a segmented and spliceable structure. Each section of the rail is connected by a double fixing method of electromagnetic adsorption and mechanical locking. Each section of the rail is internally equipped with an independent electromagnetic drive module and a position sensor. The electromagnetic drive module independently adjusts the magnetic field strength and direction inside the rail according to the instructions of the built-in PLC controller to precisely control the moving speed and acceleration of the trolley seat. The position sensor real-time monitors the position information of the trolley seat on each section of the rail and feeds it back to the built-in PLC controller to facilitate the global regulation of the movement of the trolley seat.

[0011] Preferably, two first pneumatic adjusting rods are symmetrically installed inside the trolley seat. The tops of the two first pneumatic adjusting rods are rotatably connected to the connecting frame. Two second pneumatic adjusting rods are symmetrically installed at the bottom end of the inner frame of the trolley seat. Rotating members are connected to the side ends of the two second pneumatic adjusting rods. A force-bearing contact frame is integrally formed and connected to the side end of the rotating member. A flexible contact member is installed at the side end of the force-bearing contact frame.

[0012] Preferably, the stabilizing assembly includes a mounting base rod. A circumferential driving motor is installed at the top of the side end of the mounting base rod. An angle detection seat is connected to the top output end of the circumferential driving motor. An electric parallel telescopic rod is connected to the side end of the angle detection seat. A vertical distance-adjusting telescopic guide rod is installed at the side end of the electric parallel telescopic rod. A contact pressure feedback member is installed at the bottom of the vertical distance-adjusting telescopic guide rod.

[0013] Preferably, a base plate is tightly connected to the bottom of the operation base. A longitudinal linear guide rail is installed on the surface of the base plate. A transverse linear guide rail is slidably connected to the top inside of the longitudinal linear guide rail. A phase change material contact column is connected to the top inside of the transverse linear guide rail through a micro telescopic device. A matrix welding heat dissipation point is installed on the bottom wall of the central groove of the operation base. The top of the phase change material contact column is movably contacted with the matrix welding heat dissipation point.

[0014] Preferably, the phase change material contact column is set as a multi-layer composite structure, which sequentially includes a phase change material core layer, a heat-conducting metal mesh wrapping layer, and a heat-insulating protective outer layer from the inside to the outside. The phase change material core layer uses an organic-inorganic composite phase change material with high latent heat and fast phase change characteristics. The heat-conducting metal mesh wrapping layer is made of copper or aluminum alloy with high thermal conductivity and is in a three-dimensional mesh structure, wrapping the outside of the phase change material core layer. The heat-insulating protective outer layer uses a ceramic fiber material with low thermal conductivity.

[0015] A welding method of a microwave component welding device includes the following steps:

[0016] S1. First, after preprocessing the microwave component structure, the preprocessed microwave component structure is embedded and installed inside the central groove of the operation base through an external manipulator, and the four stabilizing assemblies start to work, so that the contact pressure feedback member contacts the structure to be welded inside the microwave component structure, and adjusts the pressure according to the feedback pressure information to ensure that the structure to be welded is firmly pressed;

[0017] S2. Then, according to the welding requirements of the microwave component structure, adjust the position of the semi-circular guide rail in the transverse short-path guide rail, so that the trolley seat can move flexibly on the semi-circular guide rail, and can drive the adaptive welding assembly to perform all-round and high-precision welding operations on the microwave component structure;

[0018] S3. Secondly, during the welding process, an external optical coherence tomography scanner performs real-time imaging on the welding part, monitors the changes in the microscopic structure inside the welding part in real time, and moves the phase change material contact column to below the matrix welding heat dissipation point driven by the longitudinal linear guide and the transverse linear guide, contacts the matrix welding heat dissipation point, absorbs the heat generated by welding through the phase change material core layer, quickly conducts the heat through the heat-conducting metal mesh wrapping layer, reduces heat dissipation through the heat-insulating protective outer layer, effectively controls the temperature of the welding area, and reduces the influence of thermal stress on the component:

[0019] S4. Then, after the welding is completed, each structure returns to its original position, and the quality of the welded microwave component structure is detected through a variety of non-destructive testing techniques. After passing the detection, the microwave component structure is taken to the next process by an external manipulator again.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In the present invention, with the cooperation of the adaptive welding component, by using a high-definition camera, an image analysis and processing chip, and a built-in PLC controller, the built-in PLC controller plans the best movement path and welding sequence of the carriage seat according to the detected information, combined with the segmented structure of the semi-circular guide and the electromagnetic drive module. The carriage seat moves on the semi-circular guide according to the planned path. At the same time, the rotating motor seat, the angle rotation adjustment seat, and the adjustment drive arm work together to adjust the angle and position of the welding mounting seat, so that the welder accurately aligns with the welding point. Then the welding mounting seat drives the welder (such as a laser control emitter) to start welding operations. During the welding process, an external optical coherence tomography scanner performs real-time imaging on the welding part and feeds back the internal situation of the welding part to the built-in PLC controller. The built-in PLC controller adjusts the welding parameters in real time according to the information fed back by the optical coherence tomography scanner to ensure the welding quality. At the same time, the first pneumatic adjusting rod and the second pneumatic adjusting rod inside the carriage seat will be adjusted according to the welding situation, and drive the force-bearing contact frame and the flexible contact part to contact the surface of the microwave component structure through the rotating part, further stabilizing the welding position. Overall, the adaptive welding component can approach the microwave component structure from multiple angles, realize all-round welding operations, can dynamically adjust the support position and pressure according to the surface shape of the microwave component structure and the actual situation during the welding process, provide flexible firmness and support, reduce vibration and displacement during the welding process, effectively reduce welding defects such as false soldering and pores, improve the accuracy and reliability of welding, thereby enhancing the overall performance and stability of the microwave component, reducing manual intervention and adjustment time, improving the efficiency of welding operations, and reducing production costs.

[0022] 2. In the present invention, with the cooperation of the stabilizing component, the high-precision vision recognition unit is used to identify the position and angle information of the structure to be soldered inside the microwave component structure, and the data is transmitted to the built-in PLC controller. The built-in PLC controller controls the rotation of the circumferential drive motor according to this information, drives the angle detection seat to rotate to an appropriate angle, so that the electric parallel telescopic rod can be aligned with the structure to be soldered. The angle detection seat real-time feedbacks the angle information to ensure the accuracy of angle adjustment. Then, the electric parallel telescopic rod extends, driving the vertical distance-adjusting telescopic guide rod and the contact pressure feedback component to approach the structure to be soldered of the microwave component structure horizontally. During the movement, the built-in PLC controller adjusts the extension length of the electric parallel telescopic rod in real time according to the position information feedback by the high-precision vision recognition unit to ensure accurate approach to the structure to be soldered. Then, when the electric parallel telescopic rod moves to an appropriate position, the vertical distance-adjusting telescopic guide rod extends downward, so that the contact pressure feedback component contacts the structure to be soldered of the microwave component structure. The contact pressure feedback component real-time feedbacks the contact pressure information to the PLC controller. At the same time, the built-in PLC controller adjusts the extension length of the vertical distance-adjusting telescopic guide rod according to the feedback information of the contact pressure feedback component to make the contact pressure reach the preset value, thereby stabilizing the structure to be soldered. When the pressure is insufficient, the vertical distance-adjusting telescopic guide rod will continue to extend, and when the pressure is too high, it will contract appropriately, so that the whole can real-time monitor the contact pressure and dynamically adjust according to the pressure change, which can effectively reduce the vibration and displacement of the structure to be soldered during the welding process, ensure the welding accuracy and reliability, reduce welding defects such as false soldering and welding deviation, and thus improve the welding quality and performance of the microwave component.

Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1: In this embodiment, refer to Figure 1 - Figure 7 as shown: A microwave component welding device includes an operation base 1, four groups of stabilizing components 2, an adaptive welding component 6, and a microwave component structure 7;

[0033] The four groups of stabilizing components 2 are installed at the four ends of the operation base 1. After the microwave component structure 7 undergoes pre-treatment processes such as cleaning, drying, surface treatment, and installation, it is embedded and installed in the central groove of the operation base 1 through an external manipulator. The four groups of stabilizing components 2 are used to press and stabilize the internal solder joint structure of the placed microwave component structure 7;

[0034] Two groups of transverse short-path guide rails 5 are symmetrically installed on the surface of the operation base 1. A semi-circular guide rail 4 is slidably connected inside the two groups of transverse short-path guide rails 5. The adaptive welding component 6 is slidably connected inside the semi-circular guide rail 4. The adaptive welding component 6 is used to be able to approach the microwave component structure 7 from different angles for all-round and high-precision welding operations;

[0035] The adaptive welding assembly 6 includes a trolley seat 61. A nut roller 62 is installed inside the trolley seat 61. An adapter frame 63 is installed on the surface of the frame of the trolley seat 61. A rotating motor seat 64 is installed on the top of the adapter frame 63. An angle rotation adjustment seat 65 is installed at the top end of the rotating motor seat 64. An adjustment drive arm 66 is rotatably connected inside the angle rotation adjustment seat 65. A welding mount 67 is installed at the side end of the adjustment drive arm 66. The welding mount 67 is used to install a laser control emitter or other welders. During the welding process driven by the welding mount 67, a real-time image of the welding part is taken by using an external optical coherence tomography scanner.

[0036] Each trolley seat 61 is equipped with a high-precision vision recognition unit. The high-precision vision recognition unit includes at least three high-definition cameras distributed at different angles and a supporting image analysis and processing chip. During the movement of the trolley seat 61 along the semi-circular guide rail 4, the high-definition cameras continuously capture images of the welding parts of the microwave component structure 7. The image analysis and processing chip analyzes the image data in real time to identify the precise position, size, surface condition of the welding points and the relative position relationship with the surrounding structures, and feeds the analysis results back to the built-in PLC controller of the trolley seat 61.

[0037] The semi-circular guide rail 4 adopts a segmented and spliceable structure. Each section of the rail is connected by a double fixing method of electromagnetic adsorption and mechanical locking. Each section of the rail is internally provided with an independent electromagnetic drive module and a position sensor. The electromagnetic drive module independently adjusts the magnetic field strength and direction inside the rail according to the instructions of the built-in PLC controller to precisely control the moving speed and acceleration of the trolley seat 61. The position sensor real-time monitors the position information of the trolley seat 61 on each section of the rail and feeds it back to the built-in PLC controller to facilitate the global regulation of the movement of the trolley seat 61.

[0038] Two first pneumatic adjusting rods 690 are symmetrically installed inside the trolley seat 61. The top ends of the two first pneumatic adjusting rods 690 are rotatably connected to the adapter frame 63. Two second pneumatic adjusting rods 691 are symmetrically installed at the bottom end of the inner frame of the trolley seat 61. A rotating member 692 is connected to the side ends of the two second pneumatic adjusting rods 691. A force contact frame 68 is integrally formed and connected to the side end of the rotating member 692. A flexible contact member 69 is installed at the side end of the force contact frame 68.

[0039] In a specific solution, first, the microwave component structure 7 is cleaned successively to remove surface impurities and oil stains, and then dried to prevent moisture from affecting the welding quality. Next, its surface is treated, such as by chemical activation or plasma treatment, etc., to enhance the solderability of the surface. Then, the pre-treated microwave component structure 7 is embedded and installed into the central groove of the operation base 1 through an external manipulator. Next, the four groups of stabilizing components 2 are activated to press and stabilize the solder joint structures inside the microwave component structure 7 placed in the central groove of the operation base 1. The stabilizing components 2 can adjust their own positions and pressure magnitudes according to the different shapes and structures of the microwave component structure 7 to ensure that the solder joint structures remain stable during the welding process, reducing welding defects caused by vibration or displacement. Then, the high-precision vision recognition unit carried by the trolley seat 61 starts to work. During the movement of the trolley seat 61 along the semi-circular guide rail 4, the high-definition camera continuously captures the images of the welding parts of the microwave component structure 7. The image analysis and processing chip analyzes the image data in real time, identifies the precise positions, sizes, surface conditions, and relative position relationships with the surrounding structures of the welding points, and feeds back the analysis results to the built-in PLC controller of the trolley seat 61. The built-in PLC controller plans the best movement path and welding sequence of the trolley seat 61 based on this information, combined with the segmented structure of the semi-circular guide rail 4 and the electromagnetic drive module. The trolley seat 61 moves on the semi-circular guide rail 4 according to the planned path. At the same time, the rotating motor seat 64, the angle rotation adjustment seat 65, and the adjustment drive arm 66 work together to adjust the angle and position of the welding mounting seat 67 to accurately align the welder with the welding point. Then, the welding mounting seat 67 drives the welder (such as a laser control emitter) to start the welding operation. During the welding process, the external optical coherence tomography scanner performs real-time imaging on the welding part and feeds back the internal situation of the welding part to the built-in PLC controller. The built-in PLC controller adjusts the welding parameters, such as welding power, welding speed, etc., in real time according to the information fed back by the optical coherence tomography scanner to ensure the welding quality. At the same time, the first pneumatic adjusting rod 690 and the second pneumatic adjusting rod 691 inside the trolley seat 61 will be adjusted according to the welding situation. The force contact frame 68 and the flexible contact part 69 are driven by the rotating part 692 to contact the surface of the microwave component structure 7, further stabilizing the welding position. Overall, the adaptive welding component 6 can approach the microwave component structure 7 from multiple angles to achieve all-round welding operations, can dynamically adjust the support position and pressure according to the surface shape of the microwave component structure 7 and the actual situation during the welding process, provide flexible stabilization and support, reduce vibration and displacement during the welding process, effectively reduce welding defects, such as false soldering, porosity, etc., improve the welding accuracy and reliability, thereby enhancing the overall performance and stability of the microwave component, reducing manual intervention and adjustment time, improving the efficiency of the welding operation, and reducing the production cost.

[0040] Embodiment 2: In this example, according toFigure 1 - Figure 4 As shown in Figure 4 , the stabilizing component 2 includes a mounting base rod 21. A circumferential driving motor 22 is mounted at the top end of the side of the mounting base rod 21. An angle detection seat 23 is connected to the top output end of the circumferential driving motor 22. An electric parallel telescopic rod 24 is connected to the side end of the angle detection seat 23. A vertical distance-adjusting telescopic guide rod 25 is mounted at the side end of the electric parallel telescopic rod 24. A contact pressure feedback member 26 is mounted at the bottom of the vertical distance-adjusting telescopic guide rod 25.

[0041] In a specific solution, the above-mentioned high-precision vision recognition unit is used to recognize the position and angle information of the structure to be soldered inside the microwave component structure 7, and transmit the data to the built-in PLC controller. The built-in PLC controller controls the circumferential driving motor 22 to rotate according to this information, drives the angle detection seat 23 to rotate to an appropriate angle, so that the electric parallel telescopic rod 24 can be aligned with the structure to be soldered. The angle detection seat 23 real-time feeds back the angle information to ensure the accuracy of angle adjustment. Then the electric parallel telescopic rod 24 extends, driving the vertical distance-adjusting telescopic guide rod 25 and the contact pressure feedback member 26 to approach the structure to be soldered of the microwave component structure 7 horizontally. During the movement, the built-in PLC controller adjusts the extended length of the electric parallel telescopic rod 24 in real time according to the position information fed back by the high-precision vision recognition unit to ensure accurate approach to the structure to be soldered. Then, when the electric parallel telescopic rod 24 moves to an appropriate position, the vertical distance-adjusting telescopic guide rod 25 extends downward, so that the contact pressure feedback member 26 contacts the structure to be soldered of the microwave component structure 7. The contact pressure feedback member 26 real-time feeds back the contact pressure information to the PLC controller. At the same time, the built-in PLC controller adjusts the extended length of the vertical distance-adjusting telescopic guide rod 25 according to the feedback information of the contact pressure feedback member 26 to make the contact pressure reach the preset value, so as to stabilize the structure to be soldered. When the pressure is insufficient, the vertical distance-adjusting telescopic guide rod 25 will continue to extend, and when the pressure is too high, it will contract appropriately, so that the whole can real-time monitor the contact pressure and make dynamic adjustment according to the pressure change, which can effectively reduce the vibration and displacement of the structure to be soldered during the welding process, ensure the accuracy and reliability of welding, reduce welding defects such as false soldering and welding deviation, and thus improve the welding quality and performance of the microwave component.

[0042] Embodiment 3: In this embodiment, according to Figure 1 , Figure 2 and Figure 4 As shown in Figure 1 , Figure 2 and Figure 4 , a base plate 3 is tightly connected to the bottom of the operation base 1. A longitudinal linear guide rail 8 is mounted on the surface of the base plate 3. A transverse linear guide rail 9 is slidably connected to the inner top end of the longitudinal linear guide rail 8. A phase change material contact post 10 is connected to the inner top end of the transverse linear guide rail 9 through a micro-expander. A matrix welding heat dissipation point 11 is mounted on the bottom wall of the central groove of the operation base 1. The top end of the phase change material contact post 10 and the matrix welding heat dissipation point 11 are in movable contact.

[0043] The phase change material contact column 10 is arranged as a multi-layer composite structure, which sequentially includes a phase change material core layer, a heat-conducting metal mesh wrapping layer, and a heat-insulating protection outer layer from the inside to the outside. The phase change material core layer adopts an organic-inorganic composite phase change material with high latent heat and fast phase change characteristics. The heat-conducting metal mesh wrapping layer is made of copper or aluminum alloy with high thermal conductivity and has a three-dimensional mesh structure, which is wrapped outside the phase change material core layer. The heat-insulating protection outer layer adopts a ceramic fiber material with low thermal conductivity.

[0044] In a specific solution, before welding starts, according to the welding process and the material characteristics of the microwave component structure 7, the heat generated during the welding process is estimated. When the estimated heat is large, the phase change material core layer can be pre-adjusted through an external heating or cooling device to make it in a suitable initial temperature state, so as to better absorb the heat generated during the welding process. Then, the adaptive welding component 6 starts to perform welding operations on the microwave component structure 7. At the same time, the built-in PLC controller controls the actions of the longitudinal linear guide 8 and the transverse linear guide 9 according to the welding point position information provided by the high-precision vision recognition unit, drives the phase change material contact column 10 to move below the matrix welding heat dissipation point 11 corresponding to the welding point, and according to the welding point position information, the micro-expander extends to make the top of the phase change material contact column 10 in close contact with the matrix welding heat dissipation point 11. The heat generated during the welding process is transferred from the matrix welding heat dissipation point 11 to the phase change material contact column 10 in contact with it. The phase change material core layer utilizes its high latent heat and fast phase change characteristics to absorb a large amount of heat and undergo a phase change, thereby effectively reducing the temperature rise rate in the welding area. The heat-conducting metal mesh wrapping layer quickly conducts the heat absorbed by the phase change material core layer to the entire phase change material contact column 10, improving the efficiency of heat absorption and conduction. During the welding process, if the welding point position changes (for example, the adaptive welding component 6 moves to a new welding point), the built-in PLC controller controls the longitudinal linear guide 8 and the transverse linear guide 9 to move the phase change material contact column 10 according to the real-time feedback of the high-precision vision recognition unit, so that it always remains in contact with the matrix welding heat dissipation point 11 corresponding to the current welding point, ensuring efficient thermal management. After the welding operation is completed, the phase change material contact column 10 continues to be in contact with the matrix welding heat dissipation point 11 for a period of time, slowly releasing the heat absorbed by the phase change material core layer, making the microwave component structure 7 cool evenly, reducing thermal stress and thermal deformation. When the temperature of the phase change material core layer drops to a certain degree and the microwave component structure 7 cools to a suitable temperature, the micro-expander contracts to separate the phase change material contact column 10 from the matrix welding heat dissipation point 11, and the longitudinal linear guide 8 and the transverse linear guide 9 drive the phase change material contact column 10 to return to its original position.

[0045] The wiring diagrams of the circumferential drive motor 22, the angle detection base 23, the rotating motor base 64, the force-bearing contact frame 68, and the flexible contact 69 in the present invention belong to the common general knowledge in the art. Their working principles are already known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the circumferential drive motor 22, the angle detection base 23, the rotating motor base 64, the force-bearing contact frame 68, and the flexible contact 69 will not be explained in detail.
