Description

Technical Field

[0002] Microwave components are widely used in modern communications, radar, aerospace and other fields, and their performance directly affects the working effect of the entire system. As a key process in the manufacturing process of microwave components, welding 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 becoming higher and higher. Traditional welding methods are gradually unable to meet actual needs.

[0003] At present, the motion trajectory of traditional welding equipment is relatively fixed, which is difficult to adapt to the welding needs of complex-shaped microwave components, resulting in large welding position deviations, affecting the electrical performance of the components. The heat generated during the welding process will cause thermal stress in the components, causing deformation and cracking of the components, reducing the reliability and service life of the components. At the same time, manual welding is slow, labor-intensive, and has unstable quality. Although automated welding methods such as wave soldering and reflow soldering are more efficient, they still have welding difficulties and low efficiency for some microwave components with special structures. Therefore, it is necessary to propose a microwave component welding device and a welding method thereof. Summary of the invention

[0004] The object of the present invention is to provide a microwave component welding device and a welding method thereof, so as to solve the above-mentioned background technology that the motion trajectory of traditional welding equipment is relatively fixed, and it is difficult to adapt to the welding requirements of complex-shaped microwave components, resulting in large welding position deviations, affecting the electrical performance of the components, and the heat generated during the welding process will cause thermal stress in the components, resulting in deformation and cracking of the components, reducing the reliability and service life of the components.

The welding mounting seat drives the welder to perform real-time imaging of the welding part using an external optical coherence tomography scanner during the welding process.

[0006] Preferably, the trolley seats are equipped with a high-precision visual recognition unit, which includes at least three high-definition cameras distributed at different angles and a matching image analysis and processing chip. When the trolley seat moves along the semicircular guide rail, the high-definition camera continuously captures the image of the welding part of the microwave component structure, and 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 of the welding point with the surrounding structure, and feeds back the analysis results to the built-in PLC controller of the trolley seat.

[0007] Preferably, the semicircular arc guide rail adopts a segmented splicing structure, and each section of the track is connected by a dual fixing method of electromagnetic adsorption and mechanical locking. Each section of the track is equipped with an independent electromagnetic drive module and position sensor. The electromagnetic drive module independently adjusts the magnetic field strength and direction in the track according to the instructions of the built-in PLC controller to accurately control the movement speed and acceleration of the trolley seat. The position sensor monitors the position information of the trolley seat on each section of the track in real time, and feeds it back to the built-in PLC controller, so as to facilitate global control of the movement of the trolley seat.

[0008] Preferably, two first pneumatic adjusting rods are symmetrically installed inside the trolley seat, and the top ends 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 internal frame of the trolley seat, and the side ends of the two second pneumatic adjusting rods are connected to a rotating part. The side end of the rotating part is integrally connected with a force-bearing contact frame, and a flexible contact part is installed on the side end of the force-bearing contact frame.

[0009] Preferably, the stabilizing component includes a mounting base rod, a circumferential drive motor is mounted on the top of the side end of the mounting base rod, the top output end of the circumferential drive motor is connected to an angle detection seat, the side end of the angle detection seat is connected to an electric parallel telescopic rod, the side end of the electric parallel telescopic rod is mounted on a vertical distance-adjustable telescopic guide rod, and the bottom of the vertical distance-adjustable telescopic guide rod is mounted on a contact pressure feedback component.

[0010] Preferably, the bottom of the working base is fastened to a base plate, a longitudinal linear guide is installed on the surface of the base plate, the top end of the longitudinal linear guide is slidably connected to a transverse linear guide, the top end of the transverse linear guide is connected to a phase change material contact column via a micro telescope, and a matrix welding heat dissipation point is installed on the bottom wall of the central groove of the working base, and the top end of the phase change material contact column and the matrix welding heat dissipation point form a movable contact setting.

[0011] Preferably, the phase change material contact column is configured as a multi-layer composite structure, which includes, from the inside to the outside, a phase change material core layer, a thermally conductive metal mesh wrapping layer and a thermally insulating protective outer layer. The phase change material core layer adopts an organic-inorganic composite phase change material with high latent heat and rapid phase change characteristics. The thermally conductive metal mesh wrapping layer is made of copper or aluminum alloy with high thermal conductivity and presents a three-dimensional mesh structure, which is wrapped around the outside of the phase change material core layer. The thermally insulating protective outer layer adopts a ceramic fiber material with low thermal conductivity.

[0012] A welding method of a microwave component welding device comprises the following steps: S1. After pre-processing the microwave component structure, the pre-processed microwave component structure is embedded in the central groove of the working base through an external manipulator, and the four groups of stable components start working, so that the contact pressure feedback part contacts the structure of the to-be-welded point inside the microwave component structure, and the pressure is adjusted according to the feedback pressure information to ensure that the structure of the to-be-welded point is pressed and stable; S2. Then, according to the welding requirements of the microwave component structure, the position of the semicircular arc guide rail in the transverse short path guide rail is adjusted so that the trolley seat can move flexibly on the semicircular arc guide rail, and can drive the adaptive welding component to perform all-round and high-precision welding operations on the microwave component structure; S3. Secondly, during the welding process, an external optical coherence tomography scanner is used to perform real-time imaging of the welding part, monitor the microstructural changes inside the welding part in real time, and move the phase change material contact column to the bottom of the matrix welding heat dissipation point driven by the longitudinal linear guide and the transverse linear guide, and contact the matrix welding heat dissipation point. The heat generated by welding is absorbed by the core layer of the phase change material, the heat conductive metal mesh wrapping layer conducts heat quickly, and the heat insulating protective outer layer reduces heat loss, effectively controlling the temperature of the welding area and reducing the impact of thermal stress on the components: S4. Then, when the welding is completed, each structure returns to its original position, and the quality of the microwave component structure after welding is inspected by a variety of non-destructive testing technologies. After the inspection is qualified, the microwave component structure is taken to the next process by an external robot again.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, by using a high-definition camera, an image analysis and processing chip and a built-in PLC controller in cooperation with an adaptive welding component, the built-in PLC controller plans the best moving path and welding sequence of the trolley seat according to the detected information, combined with the segmented structure of the semicircular arc guide rail and the electromagnetic drive module. The trolley seat moves on the semicircular arc guide rail 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 is accurately aligned with the welding point. Then the welding mounting seat drives the welder (such as a laser control transmitter) to start the welding operation. During the welding process, an external optical coherence tomography scanner performs real-time imaging of the welding part, and feeds back the situation inside the welding part to the built-in PLC controller. The built-in PLC controller generates a signal according to the optical coherence tomography scanner. Feedback information is used to adjust welding parameters in real time to ensure welding quality. At the same time, the first pneumatic adjustment rod and the second pneumatic adjustment rod inside the trolley seat will be adjusted according to the welding situation, and the force contact frame and the flexible contact member will be driven by the rotating part to contact the surface of the microwave component structure to further stabilize the welding position. The adaptive welding component can approach the microwave component structure from multiple angles to achieve all-round welding operations. It 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 stability and support, reduce vibration and displacement during welding, and effectively reduce welding defects such as cold solder joints and pores, thereby improving the accuracy and reliability of welding, thereby improving 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.

[0014] 2. In the present invention, a high-precision visual recognition unit is used to identify the position and angle information of the structure to be welded inside the microwave component structure in cooperation with a stable component, and the data is transmitted to a built-in PLC controller, so that the built-in PLC controller controls the rotation of the circular drive motor based on this information, drives the angle detection seat to rotate to a suitable angle, and enables the electric parallel telescopic rod to align with the structure to be welded. The angle detection seat feeds back the angle information in real time to ensure the accuracy of the angle adjustment. Then the electric parallel telescopic rod is extended to drive the vertical adjustable telescopic guide rod and the contact pressure feedback member to horizontally approach the structure to be welded of the microwave component structure. During the movement, the built-in PLC controller adjusts the extension length of the electric parallel telescopic rod in real time based on the position information fed back by the high-precision visual recognition unit to ensure accurate approach to the welded point. Then, when the electric parallel telescopic rod moves to a suitable position, the vertical adjustable telescopic guide rod is extended downward to make the contact pressure feedback member contact the structure to be welded of the microwave component structure, and the contact pressure feedback member feeds back the contact pressure in real time. The force information is given to the PLC controller. At the same time, the built-in PLC controller adjusts the extension length of the vertical adjustable telescopic guide rod according to the feedback information of the contact pressure feedback part, so that the contact pressure reaches the preset value, thereby stabilizing the structure of the soldering point. When the pressure is insufficient, the vertical adjustable telescopic guide rod will continue to extend, and when the pressure is too large, it will shrink appropriately, so that the overall contact pressure can be monitored in real time and dynamically adjusted according to the pressure change, which can effectively reduce the vibration and displacement of the structure of the soldering point during the welding process, ensure the accuracy and reliability of welding, reduce welding defects such as cold soldering and welding deviation, thereby improving the welding quality and performance of microwave components.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Embodiment 1: In this embodiment, refer to Figure 1 - Figure 7 As shown: A microwave component welding device includes a working base 1, four sets of stabilizing components 2, an adaptive welding component 6 and a microwave component structure 7; Four sets of stabilizing components 2 are installed at the four ends of the working base 1. After the microwave component structure 7 has been cleaned, dried, surface treated and pre-installed, it is embedded in the central groove of the working base 1 through an external manipulator. The four sets of stabilizing components 2 are used to pressurize and stabilize the structure of the soldering points inside the microwave component structure 7 after placement; Two groups of transverse short-path guide rails 5 are symmetrically installed on the surface of the working base 1. The two groups of transverse short-path guide rails 5 are slidably connected to the semicircular guide rails 4. The adaptive welding assembly 6 is slidably connected to the semicircular guide rails 4. The adaptive welding assembly 6 is used to approach the microwave assembly structure 7 from different angles to perform all-round and high-precision welding operations. The adaptive welding assembly 6 includes a trolley seat 61, a nut roller 62 is installed inside the trolley seat 61, a connecting frame 63 is installed on the frame surface of the trolley seat 61, a rotating motor seat 64 is installed on the top of the connecting frame 63, an angle rotation adjustment seat 65 is installed on the top of the rotating motor seat 64, the internal rotation of the angle rotation adjustment seat 65 is connected to an adjustment drive arm 66, and a welding mounting seat 67 is installed on the side end of the adjustment drive arm 66. The welding mounting seat 67 is used to install a laser control transmitter or other welders. The welding mounting seat 67 drives the welder to perform real-time imaging of the welding part using an external optical coherence tomography scanner during the welding process.

[0019] The trolley seats 61 are all equipped with a high-precision visual recognition unit, which includes at least three high-definition cameras distributed at different angles and a matching image analysis and processing chip. When the trolley seat 61 moves along the semicircular guide rail 4, the high-definition camera continuously captures the welding part image of the microwave component structure 7, and 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 of the welding point with the surrounding structure, and feeds back the analysis results to the built-in PLC controller of the trolley seat 61.

[0020] The semicircular arc guide rail 4 adopts a segmented and splicable structure. Each section of the track is connected by a dual fixing method of electromagnetic adsorption and mechanical lock. Each section of the track is equipped with an independent electromagnetic drive module and position sensor. The electromagnetic drive module independently adjusts the magnetic field strength and direction in the track according to the instructions of the built-in PLC controller to accurately control the movement speed and acceleration of the trolley seat 61. The position sensor monitors the position information of the trolley seat 61 on each section of the track in real time, and feeds it back to the built-in PLC controller to facilitate global control of the movement of the trolley seat 61.

[0021] Two first pneumatic adjusting rods 690 are symmetrically installed inside the trolley seat 61, and the top ends of the two first pneumatic adjusting rods 690 are rotatably connected to the connecting frame 63. Two second pneumatic adjusting rods 691 are symmetrically installed at the bottom end of the internal frame of the trolley seat 61, and the side ends of the two second pneumatic adjusting rods 691 are connected to a rotating member 692. The side end of the rotating member 692 is integrally formed with a force-bearing contact frame 68, and a flexible contact member 69 is installed on the side end of the force-bearing contact frame 68.

[0022] In a specific scheme, the microwave component structure 7 is first cleaned in sequence to remove surface impurities and oil stains, and then dried to prevent moisture from affecting the welding quality. Then, its surface is treated, such as by chemical activation or plasma treatment, to enhance the surface weldability. After that, the pre-treated microwave component structure 7 is embedded and installed into the central groove of the working base 1 by an external manipulator. Then, the four groups of stabilizing components 2 are started to pressurize and stabilize the structure of the to-be-welded point inside the microwave component structure 7 placed in the central groove of the working base 1. The stabilizing component 2 can adjust its own position and pressure according to the different shapes and structures of the microwave component structure 7 to ensure that the structure of the to-be-welded point remains stable during the welding process. The high-precision visual recognition unit carried by the trolley seat 61 starts to work. When the trolley seat 61 moves along the semicircular guide rail 4, the high-definition camera continuously captures the image of the welding part of the microwave component structure 7. The image analysis and processing chip analyzes the image data in real time, identifies the precise position, size, surface condition and relative position relationship of the welding point with the surrounding structure, and feeds the analysis results back to the built-in PLC controller of the trolley seat 61, so that the built-in PLC controller plans the best moving path and welding sequence of the trolley seat 61 according to this information, combined with the segmented structure and electromagnetic drive module of the semicircular guide rail 4. The trolley seat 61 moves along the semicircular guide rail according to the planned path. 4, and at the same time, the rotating motor seat 64, the angle rotating adjustment seat 65 and the adjusting driving arm 66 work together to adjust the angle and position of the welding mounting seat 67 so that the welder is accurately aligned with the welding point. Then the welding mounting seat 67 drives the welder (such as a laser control transmitter) to start the welding operation. During the welding process, the external optical coherence tomography scanner performs real-time imaging of 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 adjustment rod 690 and the second pneumatic adjustment rod 691 inside the trolley seat 61 will adjust the welding parameters according to the welding process. The rotating member 692 drives the force contact frame 68 and the flexible contact member 69 to contact the surface of the microwave component structure 7, thereby further stabilizing the welding position. As a whole, the adaptive welding component 6 can approach the microwave component structure 7 from multiple angles to achieve all-round welding operations. The supporting position and pressure can be dynamically adjusted according to the surface shape of the microwave component structure 7 and the actual situation during the welding process, so as to provide flexible stability and support, reduce vibration and displacement during the welding process, effectively reduce welding defects such as cold welding and pores, and improve the accuracy and reliability of welding, thereby improving 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.

[0023] Embodiment 2: In this embodiment, according to Figure 1 - Figure 4 As shown, the stabilizing component 2 includes a mounting base rod 21, a circumferential drive motor 22 is mounted on the top of the side end of the mounting base rod 21, the top output end of the circumferential drive motor 22 is connected to an angle detection seat 23, the side end of the angle detection seat 23 is connected to an electric parallel telescopic rod 24, a vertical distance-adjustable telescopic guide rod 25 is mounted on the side end of the electric parallel telescopic rod 24, and a contact pressure feedback component 26 is mounted on the bottom of the vertical distance-adjustable telescopic guide rod 25.

[0024] In a specific solution, the high-precision visual recognition unit is used to identify the position and angle information of the structure to be welded inside the microwave component structure 7, and the data is transmitted to the built-in PLC controller, so that the built-in PLC controller controls the rotation of the circular drive motor 22 according to the information, drives the angle detection seat 23 to rotate to a suitable angle, so that the electric parallel telescopic rod 24 can be aligned with the structure to be welded, and the angle detection seat 23 feeds back the angle information in real time to ensure the accuracy of the angle adjustment, and then the electric parallel telescopic rod 24 is extended to drive the vertical adjustable telescopic guide rod 25 and the contact pressure feedback member 26 to horizontally approach the structure to be welded of the microwave component structure 7. During the movement, the built-in PLC controller adjusts the extension length of the electric parallel telescopic rod 24 in real time according to the position information fed back by the high-precision visual recognition unit to ensure accurate approach to the welded point, and then when the electric parallel telescopic rod 24 is extended, the vertical adjustable telescopic guide rod 25 and the contact pressure feedback member 26 are extended to horizontally approach the structure to be welded of the microwave component structure 7. After the telescopic rod 24 moves to the appropriate position, the vertical adjustable telescopic guide rod 25 extends downward, so that the contact pressure feedback member 26 contacts the structure of the to-be-welded point of the microwave component structure 7. The contact pressure feedback member 26 feeds back the contact pressure information to the PLC controller in real time. At the same time, the built-in PLC controller adjusts the extension length of the vertical adjustable telescopic guide rod 25 according to the feedback information of the contact pressure feedback member 26, so that the contact pressure reaches a preset value, thereby stabilizing the structure of the to-be-welded point. When the pressure is insufficient, the vertical adjustable telescopic guide rod 25 will continue to extend, and when the pressure is too large, it will shrink appropriately, so that the overall contact pressure can be monitored in real time and dynamically adjusted according to the pressure change, which can effectively reduce the vibration and displacement of the structure of the to-be-welded point during welding, ensure the accuracy and reliability of welding, reduce welding defects such as cold welding and welding deviation, thereby improving the welding quality and performance of microwave components.

[0025] Embodiment 3: In this embodiment, according to Figure 1 , Figure 2 and Figure 4 As shown, the bottom of the working base 1 is fastened with a base plate 3, a longitudinal linear guide 8 is installed on the surface of the base plate 3, a transverse linear guide 9 is slidably connected to the top of the longitudinal linear guide 8, a phase change material contact column 10 is connected to the top of the transverse linear guide 9 through a micro telescope, a matrix welding heat dissipation point 11 is installed on the bottom wall of the central groove of the working base 1, and the top of the phase change material contact column 10 and the matrix welding heat dissipation point 11 form a movable contact setting.

[0026] The phase change material contact column 10 is configured as a multi-layer composite structure, which includes, from the inside to the outside, a phase change material core layer, a heat-conducting metal mesh wrapping layer and a heat-insulating protective outer layer. The phase change material core layer adopts an organic-inorganic composite phase change material with high latent heat and rapid phase change characteristics. The heat-conducting metal mesh wrapping layer is made of copper or aluminum alloy with high thermal conductivity, presenting a three-dimensional mesh structure, and is wrapped around the outside of the phase change material core layer. The heat-insulating protective outer layer adopts a ceramic fiber material with low thermal conductivity.

[0027] In a specific solution, before welding begins, the heat generated during welding is estimated according to the welding process and the material properties of the microwave component structure 7. When the estimated heat is large, the phase change material core layer can be pre-adjusted by an external heating or cooling device to put it in a suitable initial temperature state to better absorb the heat generated during welding. Then the adaptive welding component 6 starts welding the microwave component structure 7, and at the same time, the built-in PLC controller controls the longitudinal linear guide 8 and the transverse linear guide 9 according to the welding point position information provided by the high-precision visual recognition unit, driving the phase change material contact column 10 to move to the bottom of the matrix welding heat dissipation point 11 corresponding to the welding point, and according to the welding point position information, the micro telescope 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 welding is transferred to the phase change material contact column 10 in contact with it through the matrix welding heat dissipation point 11. The phase change material core layer utilizes its high latent heat and rapid phase change characteristics to absorb a large amount of heat and undergo phase change, thereby effectively reducing the welding area. The temperature rise rate is reduced, and the heat-conducting metal mesh wrapping layer quickly conducts the heat absorbed by the core layer of the phase change material to the entire phase change material contact column 10, thereby improving the efficiency of heat absorption and conduction. During the welding process, if the position of the welding point 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 visual recognition unit, so that it always keeps 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 contact with the matrix welding heat dissipation point 11 for a period of time, slowly releasing the heat absorbed by the core layer of the phase change material, so that the microwave component structure 7 is evenly cooled, and thermal stress and thermal deformation are reduced. When the temperature of the core layer of the phase change material drops to a certain level and the microwave component structure 7 is cooled to a suitable temperature, the micro-retractor 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.

[0028] The wiring diagram of the circular drive motor 22, angle detection seat 23, rotating motor seat 64, force contact frame 68 and flexible contact piece 69 in the present invention is common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the circular drive motor 22, angle detection seat 23, rotating motor seat 64, force contact frame 68 and flexible contact piece 69 will no longer be explained in detail.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
