Description

Technical Field

[0001] This application relates to the field of automated clamping and flipping technology, and in particular to an antenna radome housing clamping and flipping mechanism and its clamping method. Background Technology

[0002] In the field of communication equipment manufacturing, the radome, as a key component protecting the internal antenna, directly affects signal transmission performance due to its assembly accuracy. Currently, automated production lines generally use robotic arms or pneumatic clamps to handle the antenna housing, facilitating its assembly with the connecting ring to be assembled. However, for radomes with annular thin-walled structures, traditional clamping methods are prone to deformation or positioning deviations.

[0003] For example, when using a vacuum suction cup array to adsorb the radome, the outer surface of the radome is usually adsorbed by negative pressure, but it has poor adaptability to curved surfaces and high energy consumption; when using an electromagnet group to attract the radome in opposite directions, the metal reinforcing ring is usually clamped by electromagnetic force, but the workpiece must have magnetic permeability and there is a risk of residual magnetic interference.

[0004] The aforementioned technologies have drawbacks, such as vacuum adsorption being prone to failure due to uneven surfaces, and electromagnetic solutions being limited by materials and difficult to control temperature. Further improvements are needed to address these issues. Summary of the Invention

[0005] The purpose of this application is to provide an antenna radome housing clamping and flipping mechanism and its clamping method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: an antenna radome housing clamping and flipping mechanism, comprising: The movable connecting frame can move along the length of the conveyor beam on the production line; The first rotating platform is located on one side of the movable connecting frame; The clamping mechanism includes a base plate, a sliding seat, a clamping claw, and a tray. The base plate is mounted on the output end of the first rotating platform. The sliding seat is slidably connected to the base plate. At least two sliding seats are provided, and the two sliding seats are controlled to move closer to or further away from each other. The clamping claw is slidably connected to the sliding seat, and an elastic buffer is provided between the side of the clamping claw away from the center line of the two sliding seats and the sliding seat. The tray is mounted on the clamping end of the clamping claw. The top side of the tray can abut against the bottom side of the antenna housing, and the clamping end of the clamping claw can abut against the side of the antenna housing.

[0007] By adopting the above technical solution, the movable connecting frame can adapt to the continuous assembly requirements of the assembly line. This allows the movable connecting frame to drive the clamping mechanism to adjust its position between different workstations on the assembly line, ensuring that the clamping mechanism can accurately align with the antenna housing at the previous workstation. This allows the antenna housing to be transported to the current workstation, effectively improving assembly efficiency. The two sliding seats can move closer or further apart, allowing the clamping jaws to accurately clamp the antenna housing to be assembled. The clamping jaws can also clamp antenna housings of different sizes, expanding the applicability of the clamping mechanism. The clamping jaws are slidably connected to the sliding seats. Therefore, when the clamping jaws are clamping the antenna housing, if there is a slight positional deviation in the workpiece, the clamping jaws can slide on the sliding seats, and the elastic buffer between the side of the sliding seats and the clamping jaws absorbs the impact of the clamping jaws clamping the antenna housing. The impact of the antenna housing is mitigated by the elastic deformation of the elastic buffer, which offsets the impact force and prevents the clamping claws from rigidly colliding with the antenna housing and damaging the workpiece surface. The base plate is installed at the output end of the first rotating platform. When the first rotating platform drives the plate to rotate around the bottom of the moving connecting frame, the top and bottom positions of the entire clamping mechanism are reversed. The clamping claws then drive the antenna housing to flip and adjust its posture during the flipping process. This adjusts the antenna housing from the initial vertical assembly end (open end facing upward) to the final vertical state (open end facing downward), facilitating subsequent assembly processes. At the same time, during the flipping process, the tray can continuously support the antenna housing, thereby distributing some of the force on the clamping claws holding the antenna housing and effectively improving the load-bearing capacity of the clamping mechanism. This prevents the antenna housing from slipping due to excessive weight or the clamping mechanism from losing its posture during the flipping process.

[0008] Optionally, the two sliding seats are configured as a clamping group, the clamping mechanism is provided with a first clamping group and a second clamping group, the base plate is provided with a first driving component connected to the first clamping group and a second driving component connected to the second clamping group, the first driving component and the second driving component are independently controlled to make the first clamping group and the second clamping group move sequentially, and the tray is provided at the clamping end of the clamping claw of the first clamping group.

[0009] By adopting the above technical solution, the first driving component first drives the sliding seats of the first clamping group to move closer to each other, causing the clamping claws on the sliding seats to move towards the antenna housing. Since the tray is installed on the clamping claws of the first clamping group, the top side of the tray first contacts the bottom side of the housing to form an initial positioning. After the side of the clamping claws of the first clamping group abuts against the side of the housing to complete the initial clamping, the second driving component then drives the sliding seats of the second clamping group to move closer, similarly causing the side of the clamping claws on the sliding seats to abut against another area on the side of the antenna housing. The two clamping groups work together to clamp the antenna housing, avoiding housing displacement during the clamping process and effectively improving the positional accuracy of the housing after clamping.

[0010] Optionally, the tray is provided with a first plane, a slope, and a second plane connected together. The first plane is attached to and connected to the clamping claw. The slope extends away from the clamping claw to form a clamping space between the slope and the clamping claw. The second plane extends out of the edge of the clamping claw. The slope and the second plane abut against the top surface of the antenna housing assembly end before the clamping claw.

[0011] By adopting the above technical solution, when the clamping claw approaches the antenna housing, the inclined surface of the tray contacts the top surface of the workpiece assembly end before the clamping claw. As the sliding seat continues to move, the contact point between the inclined surface of the tray and the top surface of the workpiece gradually moves upward. Through the guiding effect of the inclined surface, the workpiece is slightly lifted upward, automatically correcting the small deviation of the workpiece in the Z-axis direction, thereby reducing the accuracy requirements of the clamping claw in the Z-axis when clamping the antenna housing.

[0012] Optionally, the tray is detachably connected to the bottom surface of the clamping claw, and the tray has an elongated groove to adjust the distance between the edge of the second plane extending from the clamping claw.

[0013] By adopting the above technical solution, it is easy to adjust the position of the tray on the clamping claw according to the size of different antenna housings, effectively expanding the applicable range of the clamping mechanism. At the same time, by adjusting the tray, the distance of the second plane extending from the edge of the conveying clamping claw can be adjusted, thereby ensuring that the inclined surface of the tray covers the edge of the antenna housing, avoiding the edge of the antenna housing being suspended and allowing the tray to continuously support the antenna housing.

[0014] Optionally, the sliding base further includes a magnetic component and a limiting component disposed inside. The limiting end of the limiting component is magnetically connected to the magnetic component and elastically connected to the sliding base. The other end of the limiting component is rotatably connected to the sliding base. One end of the clamping claw is provided with a slider. The top surface of the slider is provided with multiple limiting teeth along the length direction. The multiple limiting teeth can contact the limiting end of the limiting component.

[0015] By adopting the above technical solution, when the clamping claw holds the antenna housing, the magnetic component attracts the limiting end of the limiting component to the magnetic component through magnetic attraction. At this time, the limiting end is in close contact with the magnetic component. The top surface of the limiting component is elastically connected to the sliding seat through the elastic component. There is a gap between the bottom surface of the limiting component and the multiple limiting teeth on the top surface of the slider, which effectively avoids accidental contact between the limiting component and the limiting teeth. The slider can slide along the sliding seat as the clamping claw contacts the side of the antenna housing, driving the clamping claw to adjust to a suitable clamping position. After the clamping claw clamps and fixes the antenna housing, it begins to flip. The magnetic component is simultaneously energized and demagnetized, losing its attraction force on the limiting component. The limiting component rotates downward around the sliding seat under the elastic action of the elastic component, so that the limiting end contacts the limiting teeth on the top surface of the slider, forming a mechanical block to restrict the slider from sliding on the sliding seat, thereby restricting the clamping claw from sliding displacement during the clamping process after flipping.

[0016] Optionally, the bottom surface of the sliding seat is provided with a receiving groove arranged along the length direction, and the limiting member and the limiting tooth are both located in the receiving groove.

[0017] By adopting the above technical solution, the top surface of the slider can directly slide along the bottom surface of the sliding seat, effectively reducing sliding resistance and facilitating the sliding of the slider. At the same time, when the slider slides along the sliding seat, the limiting teeth on the top surface of the slider can only move along the length of the receiving groove, so that the limiting teeth and the limiting end of the limiting member are always in the same vertical plane, avoiding misalignment between the limiting member and the limiting teeth when the limiting clamping claw is required.

[0018] Optionally, the radome housing clamping and flipping mechanism further includes: An inner support mechanism is provided on the other side of the movable connecting frame. The inner support mechanism includes a driving member and an inner support device. The output end of the driving member is fixedly connected to the inner support device. The driving member can drive the output side of the inner support device to rotate and extend radially along the driving member so that the output side of the inner support device abuts against the inner wall of the connecting ring.

[0019] By adopting the above technical solution, the inner support mechanism is installed on the other side of the movable connecting frame, which allows the movable connecting frame to drive the inner support mechanism to adjust its position between different workstations on the assembly line. This ensures that the inner support mechanism can accurately grab the connecting ring from the previous workstation and transport it to the current workstation, effectively improving assembly efficiency. The driving component transmits power to the inner support device through the linear motion of the output end, thereby driving the inner support mechanism to extend radially. This allows the extended end of the inner support mechanism to fit tightly against the inner wall of the connecting ring, providing internal support and fixing the connecting ring through friction. This ensures that the supporting force is evenly distributed on the inner wall of the connecting ring, reducing the risk of deformation caused by external clamping. At the same time, the controllability of the radial extension of the inner support device allows the inner support mechanism to adapt to connecting rings with different inner diameters.

[0020] Optionally, the internal support device includes: The first connecting seat is installed on one side of the movable connecting frame. The driving component is installed on the first connecting seat. The center of the first connecting seat is connected to the output end of the driving component. Multiple symmetrically arranged first driving links are rotatably connected to the edge of the first connecting seat. The second connecting seat is fixedly connected to the output end of the driving component at its center. Multiple symmetrically arranged second driving links are rotatably connected to the edge of the second connecting seat. One end of the second driving link is movably hinged to the first driving link, and the other end of the second driving link is provided with an abutment block that can abut against the inner wall of the connecting ring.

[0021] By adopting the above technical solution, the first connecting seat is fixedly installed on the movable connecting frame, and the output end of the driving component is set to pass through the center of the first connecting seat, so that the center of the second connecting seat is fixed with the output end of the driving component, thereby making the first connecting seat and the second connecting seat coaxially arranged, and enabling the second connecting seat to move linearly along the axis with the output end of the driving component, thereby pushing multiple symmetrically arranged first and second driving links to be radially distributed with the axis as the center, so that the movement trajectory of each group of links is symmetrical about the axis, and the supporting force is evenly distributed on the inner wall of the connecting ring. One end of the second driving link is hinged to the first driving link. When the output end of the driving component pushes the second connecting seat to move axially in the positive direction, the axial distance between the second connecting seat and the first connecting seat is extended, and the hinge point between the second driving link and the first connecting seat slides outward along the central axis of the first driving link, thereby causing the second driving link to swing outward around the rotational connection point with the second connecting seat, and the connecting block at the end of the second driving link moves radially outward until it tightly abuts against the inner wall of the connecting ring.

[0022] Optionally, the movable connecting frame includes a first connecting frame and a second connecting frame arranged opposite to each other, and a second rotating platform is connected between the first connecting frame and the second connecting frame. The clamping mechanism and the inner support mechanism are installed on both sides of the second connecting frame. The second rotating platform can drive the clamping mechanism and the inner support mechanism to rotate radially along the second connecting frame so that the positions of the clamping mechanism and the inner support mechanism are interchanged.

[0023] By adopting the above technical solution, after the mobile connecting frame transports the antenna housing and connecting ring to be assembled from the previous station to the current station through the clamping mechanism and the inner support mechanism, the clamping device flips the antenna housing so that its opening faces downwards, and the inner support mechanism simultaneously places the connecting ring in the next station. Subsequently, the mobile connecting frame rotates radially around itself through the second rotating platform, causing the clamping mechanism and the inner support mechanism to exchange positions, and making the opening end of the antenna housing correspond to the connecting end face of the connecting ring. This facilitates the subsequent assembly of the antenna housing and connecting ring in subsequent stations, and eliminates the need for additional handling mechanisms to further simplify the assembly process.

[0024] On the other hand, the antenna radome housing clamping method provided in this application adopts the following technical solution: An antenna radome housing clamping method includes the following steps: S1. The mobile connecting frame moves along the length of the conveyor beam of the production line and is positioned in the antenna housing placement area of ​​the previous station. The clamping mechanism is aligned with the target workpiece. S2. The sliding seat with relative control approaches, the tray first contacts the bottom of the antenna housing to form initial positioning, and the side of the clamping claw abuts against the antenna housing to complete the initial clamping; S3. Start the first rotating platform, drive the substrate to rotate around the bottom of the moving connecting frame, the clamping mechanism flips with the substrate, and drive the antenna housing from the initial vertical state to the final vertical state. During the flipping process, the tray continues to support the bottom side of the housing. S4. The mobile connecting frame transports the clamping mechanism to the current workstation, starts the second rotating platform, and drives the clamping mechanism to rotate radially along the mobile connecting frame. The clamping mechanism drives the antenna housing to be positioned in the antenna housing placement area of ​​the next workstation.

[0025] By adopting the above technical solution, the clamping mechanism moves synchronously with the moving frame, thereby completing the alignment of the antenna housing. A clamping space is formed between the inclined surface of the tray and the clamping claws of the first clamping group. The inclined surface of the tray contacts the top surface of the housing before the clamping claws. Guided by the sliding seat approaching the inclined surface, the housing is slightly lifted upwards, automatically correcting minor deviations in the Z-axis. After the first clamping group completes the tray support and initial side clamping, the second clamping group moves to clamp another area on both sides of the antenna housing. The two clamping groups provide stable constraint for the antenna housing, providing bottom support and symmetrical clamping on both sides. A first rotating platform drives the substrate to flip. The tray continuously supports the bottom side of the antenna housing, ensuring that the center of gravity of the antenna housing is always located at the center of symmetry of the clamping mechanism during the flipping process. This avoids uneven force on the clamping claws due to the shift of the center of gravity. During the flipping, the weight of the housing is shared by the tray and the clamping claws, thereby reducing the force on the clamping claws and effectively improving the stability of the clamping. This prevents slippage due to insufficient clamping force. The rotation of the second rotating platform drives the second connecting frame of the moving connecting frame to rotate radially, which in turn drives the clamping mechanism to rotate radially along the moving connecting frame. This allows the clamping mechanism to position the antenna housing to the antenna housing placement area of ​​the next work station, completing the initial coarse positioning.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The tray is designed to continuously support the antenna housing via an inclined surface, thereby distributing some of the force exerted on the antenna housing by the clamping claws. This effectively improves the load-bearing capacity of the clamping mechanism and prevents the antenna housing from slipping due to excessive weight or insufficient clamping force during rotation.

[0027] 2. By setting the inclined surface of the tray, when the clamping jaws approach the antenna housing, they contact the top surface of the workpiece assembly end before the clamping jaws. Thus, the inclined surface guides the workpiece slightly upward, automatically correcting the small deviation of the workpiece in the Z-axis direction, thereby reducing the accuracy requirements of the clamping jaws in the Z-axis when clamping the antenna housing.

[0028] 3. The magnetic component loses its attraction to the limiting component after being demagnetized by power, allowing the limiting end of the limiting component to contact the limiting teeth on the top surface of the slider, forming a mechanical block that restricts the slider from sliding on the sliding seat, and thus restricts the gripper from sliding displacement during the clamping process after flipping.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0032] Please see Figures 1-4This application discloses an antenna housing clamping and flipping mechanism, including: a movable connecting frame 1, a first rotating platform 2, and a clamping mechanism 3. The movable connecting frame 1 can move along the length of the conveyor beam of the production line; the first rotating platform 2 is disposed on one side of the movable connecting frame 1; the clamping mechanism 3 includes a base plate 31, a sliding seat 32, a clamping claw 33, and a tray 34. The base plate 31 is mounted on the output end of the first rotating platform 2, the sliding seat 32 is slidably connected to the base plate 31, at least two sliding seats 32 are provided, and the two sliding seats 32 are controlled to move closer or further away from each other; the clamping claw 33 is slidably connected to the sliding seat 32, and an elastic buffer 35 is provided between the side of the clamping claw 33 away from the center line of the two sliding seats 32 and the sliding seat 32; the tray 34 is mounted on the clamping end of the clamping claw 33, the top side of the tray 34 can abut against the bottom side of the antenna housing, and the clamping end of the clamping claw 33 can abut against the side of the antenna housing.

[0033] Example 1 Please see Figures 2-4 The movable connecting frame 1 is designed to move along the length of the conveyor beam on the production line, allowing it to adapt to the continuous assembly requirements of the assembly line. This enables the movable connecting frame 1 to drive the clamping mechanism 3 to adjust its position between different workstations on the assembly line, ensuring that the clamping mechanism 3 can accurately align with the antenna housing at the previous workstation. This allows the antenna housing to be transported to the current workstation, effectively improving assembly efficiency. The two sliding seats 32 can move closer or further apart, thereby driving the clamping claws 33 to accurately clamp the antenna housing to be assembled. Furthermore, the clamping claws 33 can clamp antenna housings of different sizes. The antenna housing is made of a certain size to expand the applicability of the clamping mechanism 3. The clamping claw 33 is slidably connected to the sliding seat 32. When the clamping claw 33 clamps the antenna housing, if there is a slight positional deviation of the antenna housing, the clamping claw 33 can slide on the sliding seat 32. The elastic buffer 35 between the side of the sliding seat 32 and the clamping claw 33 absorbs the impact when the clamping claw 33 clamps the antenna housing. The impact force is offset by the elastic deformation of the elastic buffer 35 itself, so as to avoid the clamping claw 33 rigidly colliding with the antenna housing and damaging the surface of the antenna housing. The elastic buffer 35 is set as a spring.

[0034] Please see Figures 2-4The substrate 31 is mounted on the output end of the first rotating platform 2. When the first rotating platform 2 drives the substrate 31 to rotate around the bottom of the movable connecting frame 1, the top and bottom positions of the entire clamping mechanism 3 are reversed. Then, the clamping claw 33 drives the antenna housing to flip and adjust its posture during the flipping process. This adjusts the antenna housing from the initial vertical assembly end (open end facing upward) to the final vertical state (open end facing downward), which facilitates the subsequent assembly process of the antenna housing. At the same time, during the flipping process, the tray 34 can continuously support the antenna housing, thereby distributing some of the force on the antenna housing held by the clamping claw 33, effectively improving the load-bearing capacity of the clamping mechanism 3, and preventing the antenna housing from slipping due to excessive weight or the clamping mechanism 3 losing its posture control during the flipping process.

[0035] Please see Figures 3-4 The two sliding seats 32 are configured as a clamping group. The clamping mechanism 3 is provided with a first clamping group and a second clamping group. The base plate 31 is provided with a first driving component 36 connected to the first clamping group and a second driving component 37 connected to the second clamping group. The first driving component 36 and the second driving component 37 are independently controlled to make the first clamping group and the second clamping group move sequentially. The tray 34 is disposed at the clamping end of the clamping claw 33 which is slidably connected to the first clamping group. The first driving component 36 first drives the sliding seats 32 of the first clamping group to move closer to each other, driving the clamping claw 33 located on the sliding seats 32 to move towards the antenna housing. Since the tray 34 is installed... On the clamping claws 33 of the first clamping group, the top side of the tray 34 first contacts the bottom side of the housing to form an initial positioning. After the side of the clamping claws 33 of the first clamping group abuts against the side of the housing to complete the initial clamping, the second driving component 37 drives the sliding seat 32 of the second clamping group to approach, which also causes the side of the clamping claws 33 on the sliding seat 32 to abut against another area of ​​the side of the antenna housing. The two clamping groups work together to clamp the antenna housing, avoiding housing displacement during the clamping process and effectively improving the positional accuracy of the housing after clamping. The bottom surface of the substrate 31 is provided with a first slide rail 311, and one side of the sliding seat 32 is slidably connected to the first slide rail 311.

[0036] Please see Figure 5 Both the first drive assembly 36 and the second drive assembly 37 are configured as tensioning pulley 363 belt drive mechanisms. Taking the first drive assembly 36 as an example, it includes a drive wheel 361, a conveyor belt 362, a tensioning pulley 363, a bidirectional lead screw 364, and a drive motor 365. There are two drive wheels 361. The two drive wheels 361 are respectively connected to the drive motor 365 and the bidirectional lead screw 364, and the force of the drive motor 365 is transmitted to the bidirectional lead screw 364 through the conveyor belt 362. The sliding seats 32 are installed on both sides of the bidirectional lead screw 364 and are driven by the bidirectional lead screw 364 to move closer or further away from each other along the first slide rail 311.

[0037] Please see Figure 6The tray 34 is provided with a first plane 341, an inclined plane 342, and a second plane 343 connected together. The first plane 341 is attached to and connected to the clamping claw 33. The inclined plane 342 extends away from the clamping claw 33 to form a clamping space between the inclined plane 342 and the clamping claw 33. The second plane 343 extends out of the edge of the clamping claw 33. When the clamping claw 33 approaches the antenna housing, the inclined plane 342 and the second plane 343 abut against the top surface of the antenna housing assembly end before the clamping claw 33. As the sliding seat 32 continues to move, the contact point between the inclined plane 342 of the tray 34 and the top surface of the antenna housing gradually moves upward. The antenna housing is slightly lifted upward by the guiding action of the inclined plane 342, which automatically corrects the small deviation of the antenna housing in the Z-axis direction, thereby reducing the accuracy requirement of the clamping claw 33 in the Z-axis when clamping the antenna housing.

[0038] Please see Figure 3 and Figure 6 The tray 34 is detachably connected to the bottom surface of the clamping claw 33. The tray 34 has an elongated groove 344 to adjust the distance of the second plane 343 extending from the edge of the clamping claw 33. This allows for easy adjustment of the position of the tray 34 on the clamping claw 33 according to the size of different antenna housings, effectively expanding the applicability of the clamping mechanism 3. At the same time, by sliding the tray 34, the distance of the second plane 343 extending from the edge of the conveying clamping claw 33 can be adjusted, ensuring that the inclined surface 342 of the tray 34 covers the edge of the antenna housing, preventing the edge of the antenna housing from being suspended and allowing the tray 34 to continuously support the antenna housing.

[0039] Please see Figure 2 and Figure 7 The radome housing clamping and flipping mechanism also includes an inner support mechanism 4. The inner support mechanism 4 is installed on the other side of the movable connecting frame 1, so that the movable connecting frame 1 drives the inner support mechanism 4 to adjust its position between different workstations on the assembly line. This ensures that the inner support mechanism 4 can accurately grab the connecting ring from the previous workstation and transport the connecting ring to the current workstation, effectively improving assembly efficiency. The inner support mechanism 4 includes a driving component 41 and an inner support device 42. The output end of the driving component 41 is fixedly connected to the inner support device 42, so that the linear motion of the output end of the driving component 41 transmits power to the inner support device 42, thereby driving the output side of the inner support device 42 to rotate and extend radially along the driving component 41. This allows the extended end of the inner support mechanism 4 to fit tightly against the inner wall of the connecting ring, providing internal support and fixing the connecting ring through friction. This ensures that the supporting force is evenly distributed on the inner wall of the connecting ring, reducing the risk of deformation caused by external clamping. At the same time, the controllability of the radial extension of the inner support device 42 allows the inner support mechanism 4 to adapt to connecting rings with different inner diameters.

[0040] Please see Figure 7The internal support device 42 includes a first connecting seat 421 and a second connecting seat 422. The first connecting seat 421 is installed on one side of the movable connecting frame 1, and the driving member 41 is installed on the first connecting seat 421. The center of the first connecting seat 421 is connected to the output end of the driving member 41. Multiple symmetrically arranged first driving connecting rods 423 are rotatably connected to the edge of the first connecting seat 421. The center of the second connecting seat 422 is fixedly connected to the output end of the driving member 41, and multiple symmetrically arranged second driving connecting rods 424 are rotatably connected to the edge of the second connecting seat 422. One end of the second driving connecting rod 424 is movably hinged to the first driving connecting rod 423, and the other end of the second driving connecting rod 424 is provided with an abutment block 425 that can abut against the inner wall of the connecting ring. The first connecting seat 421 is fixedly installed on the movable connecting frame 1, and the output end of the driving member 41 is arranged to pass through the center of the first connecting seat 421, so that the center of the second connecting seat 422 is fixed to the output end of the driving member 41, thereby fixing the first connecting seat 421 to the output end of the driving member 41. The second connecting seat 421 is coaxially arranged with the second connecting seat 422, and the second connecting seat 422 can move linearly along the axis with the output end of the driving member 41, thereby pushing multiple symmetrically arranged first driving links 423 and second driving links 424 to be radially distributed with the axis as the center, so that the movement trajectory of each group of links is symmetrical about the axis, and the supporting force is evenly distributed on the inner wall of the connecting ring. One end of the second driving link 424 is hinged to the first driving link 423. When the output end of the driving member 41 pushes the second connecting seat 422 to move in the positive axial direction, the axial distance between the second connecting seat 422 and the first connecting seat 421 is extended. The hinge point of the second driving link 424 and the first connecting seat 421 slides outward along the central axis towards the outside of the first driving link 423, thereby causing the second driving link 424 to swing outward around the rotational connection point with the second connecting seat 422. The abutment block 425 at the end of the second driving link 424 moves radially outward until it tightly abuts against the inner wall of the connecting ring.

[0041] Please see Figures 1-2 The movable connecting frame 1 includes a first connecting frame 11 and a second connecting frame 12 arranged opposite to each other. A second rotating platform 5 is connected between the first connecting frame 11 and the second connecting frame 12. A clamping mechanism 3 and an inner support mechanism 4 are installed on both sides of the second connecting frame 12. The second rotating platform 5 can drive the clamping mechanism 3 and the inner support mechanism 4 to rotate radially along the movable connecting frame 1. After the movable connecting frame 1 transports the antenna housing and connecting ring to be assembled from the previous station to the current station through the clamping mechanism 3 and the inner support mechanism 4, the clamping device flips the antenna housing so that its opening faces downward. The inner support mechanism 4 simultaneously places the connecting ring in the next station. Then, the movable connecting frame 1 rotates radially around itself through the second rotating platform 5, driving the clamping mechanism 3 and the inner support mechanism 4 to exchange positions, and making the opening end of the antenna housing correspond to the connecting end face of the connecting ring, which facilitates the assembly of the antenna housing and the connecting ring in subsequent stations, and simplifies the assembly process without the need for additional handling mechanisms.

[0042] The implementation principle of Embodiment 1 is as follows: The movable connecting frame 1 moves along the length of the conveyor beam of the production line. Through one movement, it synchronously aligns with the antenna housing placement area and the connecting ring placement area of ​​the previous station, thereby aligning the clamping mechanism 3 and the inner support mechanism 4 with the target antenna housing respectively, thus conveying the antenna housing to the current station. This allows the two sliding seats 32 to move closer or further apart, thereby driving the clamping claws 33 to precisely clamp the antenna housing. The clamping claws 33 are slidably connected to the sliding seats 32. Therefore, if there is a slight positional deviation of the antenna housing when the clamping claws 33 are clamping it, the clamping claws 33 will... The device can slide on the sliding base 32, and the elastic buffer 35 between the side of the sliding base 32 and the clamping claw 33 absorbs the impact when the clamping claw 33 clamps the antenna housing. The base plate 31 is installed on the output end of the first rotating platform 2. When the first rotating platform 2 drives the base plate 31 to rotate around the bottom of the movable connecting frame 1, the top and bottom positions of the entire clamping mechanism 3 are reversed. Then, the clamping claw 33 drives the antenna housing to flip, so that the antenna housing is adjusted from the initial vertical state assembly end, i.e., the open end facing upward, to the final vertical state with the open end facing downward. At the same time, during the flipping process, the tray 34 can continuously support the antenna housing.

[0043] Example 2 Reference Figure 8 The difference between this embodiment and embodiment 1 is that the sliding seat 32 also includes a magnetic component 321 and a limiting component 322.

[0044] Reference Figure 8On the other side of the sliding base 32, a second slide rail 324, shorter than the first slide rail 311, is provided. One end of the clamping claw 33 has a slider 323, which is slidably connected to the second slide rail 324 on the sliding base 32. The slider 323 is fixedly connected to the clamping claw 33. A magnetic element 321 is disposed inside the sliding base 32. The limiting end of the limiting element 322 is magnetically connected to the magnetic element 321 and elastically connected to the sliding base 32 through an elastic element 325. The other end of the positioning member 322 is rotatably connected to the sliding seat 32. Multiple limiting teeth 326 are provided along the length of the top surface of the slider 323. These limiting teeth 326 can contact the limiting end of the positioning member 322. When the clamping claw 33 clamps the antenna housing, the magnetic member 321 attracts the limiting end of the positioning member 322 to the magnetic member 321 through magnetic attraction. At this time, the limiting end is tightly attached to the magnetic member 321, and the bottom surface of the positioning member 322 is close to the multiple limiting teeth 326 on the top surface of the slider 323. A gap is provided to effectively prevent accidental contact between the limiting member 322 and the limiting tooth 326. The slider 323 can slide along the second slide rail 324 on the sliding seat 32 as the clamping claw 33 contacts the side of the antenna housing, driving the clamping claw 33 to adjust to a suitable clamping position. After the clamping claw 33 clamps and fixes the antenna housing, it begins to rotate. The magnetic member 321 is simultaneously energized and demagnetized, losing its attraction to the limiting member 322. Under the elastic action of the elastic member 325, the limiting member 322 rotates around the sliding seat 32. Rotating downwards causes the limiting end to contact the limiting tooth 326 on the top surface of the slider 323, forming a mechanical block that restricts the slider 323 from sliding on the second slide rail 324 on the sliding seat 32, thereby limiting the sliding displacement of the clamping claw 33 during the clamping process after flipping. The magnetic component 321 is set as an electromagnet, and the elastic component 325 is set as a spring. The attraction force of the magnetic component 321 on the limiting end of the limiting component 322 is greater than the pushing force of the elastic component 325 on the limiting end of the limiting component 322.

[0045] Reference Figure 8 The bottom surface of the sliding base 32 is provided with a receiving groove 327 arranged along the length direction, so that the top surface of the slider 323 can slide directly along the bottom surface of the sliding base 32, effectively reducing sliding resistance and facilitating the sliding of the slider 323. At the same time, the limiting member 322 and the limiting tooth 326 are installed in the receiving groove 327. When the slider 323 slides along the sliding base 32, the limiting tooth 326 on the top surface of the slider 323 can only move along the length direction of the receiving groove 327, so that the limiting tooth 326 and the limiting end of the limiting member 322 are always in the same vertical plane, avoiding misalignment between the limiting member 322 and the limiting tooth 326 when the limiting clamping claw 33 is required.

[0046] The implementation principle of Embodiment 2 is as follows: The magnetic component 321 attracts the limiting end of the limiting component 322 to the magnetic component 321 through magnetic attraction. At this time, the limiting end is in close contact with the magnetic component 321. There is a gap between the bottom surface of the limiting component 322 and the multiple limiting teeth 326 on the top surface of the slider 323. The slider 323 can slide along the second slide rail 324 on the sliding seat 32 as the clamping claw 33 contacts the side of the antenna housing, driving the clamping claw 33 to adjust to a suitable clamping position. After the clamping claw 33 clamps and fixes the antenna housing, it begins to flip. The magnetic component 321 is simultaneously energized and demagnetized, losing its attraction force on the limiting component 322. Under the elastic action of the elastic component 325, the limiting component 322 rotates downward around the sliding seat 32, so that the limiting end contacts the limiting teeth 326 on the top surface of the slider 323, forming a mechanical block, thereby restricting the slider 323 from sliding on the second slide rail 324 on the sliding seat 32, and thus restricting the clamping claw 33 from sliding displacement during the clamping process after flipping.

[0047] Example 3 Please see Figures 1-8 Embodiment 3 of this application discloses a method for clamping an antenna radome housing, which includes the following steps: S1. The mobile connecting frame 1 moves along the length of the conveyor beam of the production line and is positioned in the antenna housing placement area of ​​the previous station. The clamping mechanism 3 is aligned with the target antenna housing.

[0048] Specifically, the clamping mechanism 3 is moved onto the connecting frame 1, so that the clamping mechanism 3 moves synchronously with the moving frame, thereby completing the alignment of the antenna housing.

[0049] S2. Control the relative sliding seat 32 to move closer, the tray 34 first contacts the bottom of the antenna housing to form initial positioning, and the clamping claw 33 abuts against the side of the antenna housing to complete the initial clamping.

[0050] Specifically, a clamping space is formed between the inclined surface 342 of the tray 34 of the first clamping group and the clamping claw 33. The inclined surface 342 of the tray 34 contacts the top surface of the housing before the clamping claw 33. As the sliding seat 32 approaches the inclined surface 342, the housing is slightly lifted upward, automatically correcting the slight deviation of the housing in the Z-axis. After the first clamping group completes the bearing of the tray 34 and the initial clamping of the side, the second clamping group moves again to clamp another area on both sides of the antenna housing. The two clamping groups provide stable constraint for the antenna housing by bearing the bottom surface and symmetrically clamping both sides.

[0051] According to another aspect of this application, step S2 further includes: S21, the clamping claw 33 completes clamping, the magnetic component 321 in the sliding seat 32 is energized and demagnetized, the limiting component 322 rotates around the sliding seat 32, and the limiting end of the limiting component 322 falls down and contacts the target limiting tooth 326 on the top surface of the slider 323 to fix the position of the clamping claw 33.

[0052] Specifically, the magnetic component 321 loses its attraction to the limiting component 322 after being demagnetized by power, allowing the limiting end of the limiting component 322 to contact the limiting teeth 326 on the top surface of the slider 323, forming a mechanical block to restrict the slider 323 from sliding on the sliding seat 32, thereby restricting the gripper 33 from sliding displacement during the gripping process after flipping.

[0053] S3. Start the first rotating platform 2, which drives the substrate 31 to rotate around the bottom of the movable connecting frame 1. The clamping mechanism 3 flips with the substrate 31, which drives the antenna housing from the initial vertical state to the final vertical state. During the flipping process, the tray 34 continuously supports the bottom side of the antenna housing.

[0054] Specifically, the first rotating platform 2 drives the base plate 31 to flip, and the tray 34 continuously supports the bottom side of the antenna housing. This ensures that the center of gravity of the antenna housing is always located at the center of symmetry of the clamping mechanism 3 during the flipping process, avoiding uneven force on the clamping claw 33 due to the shift of the center of gravity. The weight of the antenna housing during and after the flipping is borne by the tray 34 and the clamping claw 33, thereby reducing the force on the clamping claw 33 and effectively improving the stability of the clamping, preventing slippage due to insufficient clamping force.

[0055] S4. The mobile connecting frame 1 transports the clamping mechanism 3 to the current workstation, and starts the second rotating platform 5 to drive the clamping mechanism 3 to rotate radially along the mobile connecting frame 1. The clamping mechanism 3 drives the antenna housing to be positioned in the antenna housing placement area of ​​the next workstation.

[0056] Specifically, the rotation of the second rotating platform 5 drives the second connecting frame 12 of the movable connecting frame 1 to rotate radially, which in turn drives the clamping mechanism 3 to rotate radially along the movable connecting frame 1, thereby enabling the clamping mechanism 3 to position the antenna housing to the antenna housing placement area of ​​the next work station, completing the initial coarse positioning.

[0057] According to another aspect of this application, after step S4, the following steps are also included: S5, after the antenna housing completes the initial coarse positioning and enters the subsequent assembly process, the clamping claw 33 of the clamping mechanism 3 releases the antenna housing and flips it back to its original position, the magnetic component 321 in the sliding seat 32 is de-energized again, and attracts the limiting end of the limiting component 322 to disengage it from the limiting tooth 326, thereby releasing the mechanical obstruction, and the moving connecting frame 1 drives the clamping mechanism 3 to reset to its initial position and enter the next cycle.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
