Description

Technical Field

[0001] This invention belongs to the field of communication antenna technology, and in particular relates to a positioning device for welding communication antennas. Background Technology

[0002] A communication antenna is an essential component in wireless equipment used to transmit or receive electromagnetic waves. It is widely used in communication engineering systems such as radio communication, broadcasting, television, and navigation. To achieve a reliable, low-loss, and stable electrical connection, the communication antenna needs to be welded. Therefore, a positioning device is required to ensure the welding quality of the communication antenna.

[0003] For example, Chinese patent document (CN114054878B) discloses an automatic soldering device for RFID antenna chips. The technical problem this invention aims to solve is the existence of poor soldering and solder failures between the antenna and the chip, resulting in solder bending, affecting soldering efficiency, and even damaging the antenna and chip. The device includes a base plate, a first bolt fixing plate, and a second bolt fixing plate. The first bolt fixing plate is bolted to the right side of the upper surface of the base plate, and the second bolt fixing plate is fixed to the left side of the upper surface of the base plate. This invention, while achieving automatic soldering of the RFID chip and antenna, pre-solders the solder joints of the RFID chip with a layer of base tin, effectively preventing poor soldering between the RFID chip and the antenna. Furthermore, it prevents solder from overflowing into other parts of the RFID chip during the soldering process, thus preventing damage and, in severe cases, rendering the RFID chip unusable. This effectively reduces production costs and improves production efficiency. However, during use, this device may not be able to quickly adapt to the positioning requirements of antenna chips of different models and shapes, reducing the flexibility of the device during use. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to address the problem that existing technologies may not be able to quickly adapt to the positioning requirements of antenna chips of different models and shapes, thus reducing the flexibility of the device during use. Therefore, this invention proposes a positioning device for welding communication antennas.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning device for welding communication antennas includes a worktable, a rotating disk rotatably connected to the top side inside the worktable, and a plurality of first through holes arranged in a circular array inside the rotating disk. The device also includes:

[0007] Multiple positioning components are installed on the top of the rotating disk and directly above the first through hole. The positioning components are fixed in contact with multiple flexible fixing components distributed in a cross array to fix the communication antennas of different shapes to be welded.

[0008] The limiting component is installed on the top of the rotating disk and is located on one side of the positioning component;

[0009] A parallel positioning component is installed inside the worktable, and the parallel positioning component is located directly below the first through hole on one side;

[0010] The rotating assembly, installed inside the worktable, is used to drive the rotating disk to rotate on the worktable;

[0011] The operating unit, mounted on the top of the workbench, is used to control the operation of the device;

[0012] First, place the device in a suitable position. Then, install the external automatic welding unit on the top of the workbench in a suitable position and set the external automatic welding unit away from the parallel positioning components. The parallel positioning components realize the synchronous radial expansion and contraction of multiple positioning components, so that external machinery or personnel can place the sheet metal to be welded and the communication antenna into the positioning components in sequence. The positioning components simultaneously fix various sheet metal specifications, antenna shapes and angles, so that the device can quickly adapt to different working conditions and positioning requirements. After the fixing requirements of the sheet metal and communication antenna are completed, the positioning components are constrained by the limiting components to further ensure the fixing stability of the sheet metal and communication antenna.

[0013] Preferably, the positioning component includes:

[0014] A limiting seat is fixed to the top of the rotating disk, and multiple limiting seats are distributed equidistantly around the center of the rotating disk. The bottom side of the limiting seat is provided with a second through hole that is the same as the first through hole. The cross-sectional shape of the second through hole and the first through hole is both set to a cross shape.

[0015] A limiting groove is formed inside the top side of the limiting seat, and the bottom of the limiting groove is connected to the second through hole through a limiting sliding hole. The cross-sectional shape of the limiting groove is set to a cross shape.

[0016] The parallel positioning component moves vertically and gradually enters the first and second through holes. As the parallel positioning component moves upward, multiple positioning seats and fixed seats move synchronously away from the center of the limiting seat, realizing the synchronous radial expansion and contraction of multiple positioning seats and fixed seats, so that external machinery or personnel can place the sheet metal to be welded and the communication antenna between multiple positioning seats and fixed seats in sequence.

[0017] Preferably, the flexible fixing component includes:

[0018] The first spring is disposed inside the limiting groove, and one side of the first spring is fixedly connected to the limiting seat.

[0019] The positioning seat is disposed inside the limiting groove and is slidably connected inside the limiting groove. The cross-sectional shape of the positioning seat is set to L-shaped, and circular through holes are symmetrically opened on one side of the top of the positioning seat.

[0020] The connecting shaft is located inside the circular through hole and is rotatably connected to the top side inside the positioning seat;

[0021] Two arc-shaped seats are symmetrically arranged on both sides of the positioning seat, and the arc-shaped seats are hinged to the outer periphery of the connecting shaft. A cavity is opened on one side of the arc-shaped seat, and one side of the cavity is connected to the external air supply device through a connecting sleeve and a pipe.

[0022] The sealing sliding component is slidably sealed inside the cavity, and a fourth spring is fixedly connected to one side of the sealing sliding component. The fourth spring is fixedly connected to the inner wall of the positioning seat on one side.

[0023] A fixing seat is fixed to one side of the sealing sliding element, and a flexible layer is provided on the side of the fixing seat away from the sealing sliding element;

[0024] After the sheet metal and communication antenna are placed, the first spring will drive the positioning seat, connecting shaft, arc-shaped seat, cavity, sealing slider, and fixing seat to move synchronously towards the sheet metal and communication antenna. The bottom of the positioning seat will contact and fix with the outer surface of the sheet metal, making it adaptable to the fixing effect of sheets of different shapes or sizes, providing a stable foundation for the welding of the communication antenna. Gas is delivered to one side of the cavity through an external gas supply device, connecting pipe, and pipeline, making the pressure on that side increase. When the pressure overcomes the initial preload of the fourth spring, the sealing slider will drive the fixing seat to move linearly towards the communication antenna. The micro-position movement allows for precise adjustment of the welding angle of communication antennas by regulating the gas pressure between multiple different cavities according to actual needs. This makes the device suitable for welding complex antenna components or applications requiring specific spatial orientations. Simultaneously, the hinged connecting shaft and arc-shaped seat ensure that the fixing base fits well against the surfaces of communication antennas with different curvatures, guaranteeing the positioning and fixing requirements for communication antennas of different shapes. This allows the device to adapt to various sheet metal specifications, antenna shapes, and antenna angles without replacing core components, enabling rapid adaptation to different working conditions and significantly improving its versatility and production efficiency.

[0025] Preferably, the limiting component includes:

[0026] Multiple sets of second springs, each set consisting of two symmetrically arranged individual second springs, with one side of the second spring fixedly connected to the inner wall of the limiting seat;

[0027] Multiple sets of second limiting plates are arranged in a circular array inside the limiting seat. Each set of second limiting plates consists of two symmetrically arranged individual second limiting plates, and the two individual second limiting plates are symmetrically distributed with the positioning seat as the center.

[0028] The drive unit is used to drive two individual second limiting plates to move relative to each other in order to limit and fix the position of the positioning seat.

[0029] The inner limiting component is used to limit and fix the connecting shaft, arc-shaped seat, and fixed seat;

[0030] After the requirements for fixing the sheet metal and communication antenna are met, the second limiting plate on one side is moved towards the positioning seat by the drive unit to radially clamp and fix the positioning seat in its working position.

[0031] Preferably, the driving unit includes:

[0032] The ring gear rotates inside the limit seat via a ring slider and a ring slide rail at its bottom.

[0033] Multiple gears are meshed and connected to the inner circumference of the ring gear, and the multiple gears are distributed in a circular array with the center of the ring gear.

[0034] Multiple fixed shafts are fixed inside the gear, and the bottom of the fixed shafts is rotatably connected to the inside of the limit seat;

[0035] Multiple cams are fixedly connected to the outer periphery of a fixed shaft, and the cams are positioned above the gears;

[0036] Multiple first limiting plates are arranged in a circular array on the top of the ring gear, and the bottom of the first limiting plates is fixedly connected to the top of the ring gear;

[0037] The second motor is fixedly connected to the inner wall of the limiting seat at its bottom, and one end of the output shaft of the second motor is fixedly connected to the bottom end of the fixed shaft on one side.

[0038] After securing the sheet metal and communication antenna, the second motor is activated. This motor drives one of the fixed shafts, gears, and cams to rotate. Utilizing the linkage between the gears and the ring gear, power is transmitted to the ring gear, which in turn drives multiple other gears, the fixed shaft, and the cam to rotate. During rotation, the cam presses against the second limiting plate on one side. Simultaneously, the ring gear drives multiple first limiting plates fixed to it to move synchronously, pressing against the second limiting plate on the other side. This causes the two second limiting plates to move synchronously towards the positioning seat, radially clamping and fixing the positioning seat to its intended position. This ensures the synchronous and balanced clamping force on both sides of the positioning seat, thus fixing the sheet metal to its intended position and improving the positioning accuracy and stability of the device.

[0039] Preferably, the inner limiting component includes:

[0040] Two limiting rods are symmetrically arranged with the positioning seat as the center, and the limiting rods are slidably connected inside the positioning seat;

[0041] Two L-shaped plates are symmetrically arranged with the positioning seat as the center. One side of the L-shaped plate is fixedly connected to one end of the limiting rod, and the top side of the L-shaped plate is slidably connected to the outer periphery of the fixed shaft through the third through hole.

[0042] The third spring is sleeved on the outer periphery of the limiting rod, and the two sides of the third spring are fixedly connected to the L-shaped plate and the inner wall of the positioning seat, respectively.

[0043] During the process of fixing the positioning seat, the second limiting plate will compress the limiting rod and the third spring, causing the limiting rod to drive the L-shaped plate and the first chuck to move towards the second chuck. Through the cooperation of the second chuck and the first chuck, the positions of the connecting shaft, the arc-shaped seat and the fixed seat are limited and constrained. The limiting and fixing between the positioning seat and the fixed seat ensures the stability of the plate and the communication antenna, preventing them from moving during subsequent movement and welding, thereby ensuring the high-precision positioning effect and welding quality of the device.

[0044] Preferably, the parallel positioning component includes:

[0045] An electric actuator is fixed to the bottom inside the worktable, and the electric actuator is positioned directly below the first through hole;

[0046] A conical block is fixedly connected to the top of the electric push rod, and the cross-sectional shape of the conical block is set to a cross shape;

[0047] Multiple connecting blocks are arranged in a circular array inside the limiting seat, and the top of the connecting blocks is fixedly connected to the bottom of the positioning seat;

[0048] Multiple second cone blocks are arranged in a circumferential array inside the limiting seat, and the top of the second cone block is fixedly connected to the bottom of the connecting block. Both the second cone block and the connecting block are located inside the second through hole.

[0049] The electric push rod drives the conical block to move vertically upwards. The conical block gradually enters the first and second through holes. As the conical block continues to move upwards, it gradually contacts multiple second conical blocks in the top circular shaft array. These second conical blocks, through multiple connecting blocks, drive multiple positioning seats and fixed seats to move synchronously away from the center of the limiting seat. This allows external machinery or personnel to place the sheet metal to be welded and the communication antenna between the multiple positioning seats and fixed seats. A single electric push rod drives the central conical block to move vertically. Through the contact of the conical surfaces of the conical block and the second conical blocks, the vertical movement is converted into the radial movement of multiple circumferentially distributed second conical blocks. This achieves the synchronous radial expansion and contraction of multiple positioning seats and fixed seats. This design enables the tooling to open and close quickly and automatically, providing a clear operating space in the central area. It significantly improves the convenience and efficiency of loading and unloading sheet metal and communication antennas, and also helps to reduce the adverse effects on sheet metal and communication antennas during loading and unloading.

[0050] Preferably, the rotating unit includes:

[0051] The first motor is fixed inside the bottom side of the workbench, and a round shaft is fixedly connected to the top of the output shaft of the first motor. The top of the round shaft is fixedly connected to the bottom of the rotating disk.

[0052] The operation unit includes:

[0053] The control panel is fixed to the top of the workbench and is located on one side of the rotating disk;

[0054] The first motor drives the circular shaft and rotating disk to rotate, moving the sheet metal and communication antenna directly below the external automatic welding unit. The external automatic welding unit then performs welding on the sheet metal and communication antenna. After welding, the first motor continues to drive the circular shaft and rotating disk to rotate. When it moves directly above the electric push rod, the second motor first drives the cam and ring gear to reset. Then, the electric push rod drives the conical block and the second conical block to move upward, quickly releasing the positioning seat and the fixed seat from fixing the welded sheet metal and communication antenna, so that they can be unloaded, thereby ensuring the overall performance of the device.

[0055] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0056] 1. In this invention, through the positioning components, the first spring drives the positioning seat, connecting shaft, arc seat, cavity, sealing sliding component, and fixing seat to synchronously contact and fix plates of different shapes or sizes. Furthermore, the gas pressure between multiple different cavities can be adjusted according to actual needs, allowing for precise adjustment of the welding angle of the communication antenna. This makes the device suitable for welding complex antenna components or applications requiring specific spatial orientations. Simultaneously, the hinged connecting shaft and arc seat ensure that the fixing seat fits well against the surfaces of communication antennas with different curvatures, guaranteeing the positioning and fixing requirements for communication antennas of different shapes. This allows the device to adapt to various plate specifications, antenna shapes, and antenna angles without replacing core components, enabling rapid adaptation to different working conditions and significantly improving the device's versatility and production efficiency.

[0057] 2. In this invention, by setting a limiting component, the second motor drives one of the fixed shafts, gears, and cams to rotate, which enables the two second limiting plates to simultaneously and radially clamp and fix the positioning seat in its working position. This ensures the synchronous and balanced clamping force on both sides of the positioning seat, improving the positioning accuracy and stability of the device. At the same time, the second limiting plate will drive the L-shaped plate and the first chuck to move towards the second chuck through the limiting rod. The cooperation between the second chuck and the first chuck limits and constrains the working position of the connecting shaft, the arc-shaped seat, and the fixed seat. The limiting and fixing between the positioning seat and the fixed seat ensures the stability of the plate and the communication antenna, preventing them from moving during subsequent movement and welding, thereby ensuring the high-precision positioning effect and welding quality of the device.

[0058] 3. In this invention, a parallel positioning component is used to drive the central conical block to move vertically using a single electric push rod. The vertical movement is converted into the radial movement of multiple circumferentially distributed second conical blocks through the cooperation of the conical surfaces of the conical block and the second conical block. This achieves the synchronous radial expansion and contraction of multiple positioning seats and fixed seats. This design enables the tooling to open and close quickly and automatically, provides a clear operating space for the central area, significantly improves the convenience and efficiency of loading and unloading sheet metal and communication antennas, and helps to reduce the adverse effects on sheet metal and communication antennas during loading and unloading.

[0073] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0074] Please see Figures 1-12 The present invention provides a technical solution: a positioning device for welding communication antennas, comprising a workbench 1, a rotating disk 2 rotatably connected to the top side inside the workbench 1, and a plurality of first through holes 3 arranged in a circular array inside the rotating disk 2, and further comprising:

[0075] Multiple positioning components 5 are installed on the top of the rotating disk 2 and are directly above the first through hole 3. The positioning components 5 are fixed in contact with the communication antennas of different shapes to be welded by multiple flexible fixing components distributed in a cross array.

[0076] Limiting component 6 is installed on the top of rotating disk 2 and is located on one side of positioning component 5;

[0077] Parallel positioning component 7 is installed inside the worktable 1, and the parallel positioning component 7 is located directly below the first through hole 3 on one side;

[0078] A rotating assembly is installed inside the worktable 1 and is used to drive the rotating disk 2 to rotate on the worktable 1.

[0079] The operating unit, mounted on the top of the workbench 1, is used to control the operation of the device;

[0080] It may not be able to quickly adapt to the positioning requirements of antenna chips of different models and shapes, reducing the flexibility of the device during use;

[0081] This embodiment of the invention can solve the above problems. The specific implementation method is as follows: First, the device is placed in a suitable position. Then, the external automatic welding unit is installed in a suitable position on the top of the workbench 1 and is set on the side away from the parallel positioning component 7. The parallel positioning component 7 realizes the synchronous radial expansion and contraction of multiple positioning components 5 so that external machinery or personnel can place the sheet metal to be welded and the communication antenna into the positioning component 5 in sequence. The positioning component 5 simultaneously fixes various sheet metal specifications, various antenna shapes and various antenna angles, so that the device can quickly adapt to different working conditions and positioning requirements. After the fixing requirements of the sheet metal and the communication antenna are completed, the positioning component 5 is constrained by the limiting component 6 to further ensure the fixing stability of the sheet metal and the communication antenna.

[0082] As an optional embodiment, the positioning component 5 includes:

[0083] The limiting seat 501 is fixed to the top of the rotating disk 2, and multiple limiting seats 501 are distributed equidistantly around the center of the rotating disk 2. The bottom side of the limiting seat 501 is provided with a second through hole 503 that is the same as the first through hole 3. The cross-sectional shape of the second through hole 503 and the first through hole 3 are both set to cross shape.

[0084] The limiting groove 502 is opened inside the top side of the limiting seat 501, and the bottom of the limiting groove 502 is connected to the second through hole 503 through the limiting sliding hole. The cross-sectional shape of the limiting groove 502 is set to cross shape.

[0085] The parallel positioning component 7 is moved vertically and gradually enters the first through hole 3 and the second through hole 503. As the parallel positioning component 7 moves upward, multiple positioning seats 505 and fixed seats 510 move synchronously away from the center of the limiting seat 501, realizing the synchronous radial expansion and contraction of multiple positioning seats 505 and fixed seats 510, so that external machinery or personnel can place the plate to be welded and the communication antenna between multiple positioning seats 505 and fixed seats 510 in sequence.

[0086] As an optional embodiment, the flexible fixing component includes:

[0087] The first spring 504 is disposed inside the limiting groove 502, and one side of the first spring 504 is fixedly connected to the limiting seat 501.

[0088] The positioning seat 505 is disposed inside the limiting groove 502 and is slidably connected inside the limiting groove 502. The cross-sectional shape of the positioning seat 505 is set to L-shaped, and circular through holes are symmetrically opened on one side of the top of the positioning seat 505.

[0089] The connecting shaft 506 is disposed inside the circular through hole, and the connecting shaft 506 is rotatably connected to the top side inside the positioning seat 505;

[0090] Two arc-shaped seats 507 are symmetrically arranged on both sides of the positioning seat 505, and the arc-shaped seats 507 are hinged to the outer periphery of the connecting shaft 506. A cavity 508 is opened on one side of the arc-shaped seat 507, and one side of the cavity 508 is connected to the external air supply device through a connecting sleeve and a pipe.

[0091] The sealing sliding member 509 is slidably sealed inside the cavity 508, and a fourth spring is fixedly connected to one side of the sealing sliding member 509. The fourth spring is fixedly connected to the inner wall of the positioning seat 505.

[0092] The fixing seat 510 is fixed to one side of the sealing sliding member 509, and a flexible layer is provided on the side of the fixing seat 510 away from the sealing sliding member 509;

[0093] After the sheet metal and communication antenna are placed, the first spring 504 will drive the positioning seat 505, connecting shaft 506, arc-shaped seat 507, cavity 508, sealing sliding member 509, and fixing seat 510 to move synchronously towards the sheet metal and communication antenna. The bottom of the positioning seat 505 will contact and fix with the outer surface of the sheet metal, making it adaptable to the fixing effect of sheets of different shapes or sizes, providing a stable foundation for the welding of the communication antenna. Gas is delivered to one side of the cavity 508 through an external gas supply device, connecting pipe, and pipeline, making the pressure on one side increase. When the pressure overcomes the initial preload of the fourth spring, the sealing sliding member 509 will drive the fixing seat 510 to make a linear micro-position movement towards the communication antenna. Multiple different cavities can be adjusted according to actual needs. The gas pressure between the bodies 508 allows for precise adjustment of the welding angle of the communication antenna, making the device suitable for welding complex antenna components or applications requiring specific spatial orientation. Simultaneously, the hinged connecting shaft 506 and the arc-shaped seat 507 ensure that the fixing seat 510 fits well against the surfaces of communication antennas with different curvatures, guaranteeing the positioning and fixing requirements for communication antennas of different shapes. This allows the device to adapt to various sheet metal specifications, antenna shapes, and antenna angles without replacing core components, enabling rapid adaptation to different working conditions and positioning needs. This significantly improves the device's versatility and production efficiency. The pipeline is equipped with flow valves and pressure valves, and the external gas supply device and the precise control system for the pipeline valves are known and disclosed technologies in the art; therefore, they are not elaborated upon in this application.

[0094] As an optional embodiment, the limiting component 6 includes:

[0095] Multiple sets of second springs 607, each set of second springs 607 consists of two symmetrically arranged individual second springs 607, and one side of the second spring 607 is fixedly connected to the inner wall of the limiting seat 501;

[0096] Multiple sets of second limiting plates 606 are arranged in a circular array inside the limiting seat 501. Each set of second limiting plates 606 consists of two symmetrically arranged individual second limiting plates 606, and the two individual second limiting plates 606 are symmetrically distributed with the positioning seat 505 as the center.

[0097] A drive unit is used to drive two individual second limiting plates 606 to move relative to each other in order to limit and fix the position of the positioning seat 505.

[0098] The inner limiting component is used to limit and fix the connecting shaft 506, the arc-shaped seat 507 and the fixed seat 510;

[0099] After the requirements for fixing the sheet metal and communication antenna are met, the second limiting plate 606 on one side is moved towards the positioning seat 505 by the drive unit to radially clamp and fix the positioning seat 505 in its working position.

[0100] As an optional embodiment, the driving unit includes:

[0101] The ring gear 601 rotates inside the limit seat 501 via a ring slider and a ring slide rail at its bottom.

[0102] Multiple gears 602 are meshed and connected to the inner circumference of the ring gear 601, and the multiple gears 602 are distributed in a circular array around the center of the ring gear 601;

[0103] Multiple fixed shafts 603 are fixed inside the gear 602, and the bottom of the fixed shafts 603 are rotatably connected to the inside of the limit seat 501;

[0104] Multiple cams 604 are fixedly connected to the outer periphery of the fixed shaft 603, and the cams 604 are positioned above the gear 602;

[0105] Multiple first limiting plates 605 are arranged in a circular array on the top of the ring gear 601, and the bottom of the first limiting plates 605 is fixedly connected to the top of the ring gear 601.

[0106] The bottom of the second motor 608 is fixedly connected to the inner wall of the limiting seat 501, and one end of the output shaft of the second motor 608 is fixedly connected to the bottom end of the fixed shaft 603 on one side.

[0107] After the sheet metal and communication antenna are secured, the second motor 608 is activated. The second motor 608 drives one of the fixed shafts 603, gears 602, and cams 604 to rotate. Utilizing the linkage between gears 602 and ring gear 601, power is transmitted to the ring gear 601, causing it to drive multiple other gears 602, fixed shafts 603, and cams 604 to rotate. During rotation, the cam presses against the second limiting plate 606 on one side. Simultaneously, the ring gear 601 drives multiple first limiting plates 605, which are fixed to it, to move synchronously, pressing against the second limiting plate 606 on the other side. This causes the two second limiting plates 606 to move synchronously towards the positioning seat 505, radially clamping and fixing the positioning seat 505 to its intended position. This ensures the synchronous and balanced clamping force on both sides of the positioning seat 505, thus fixing the sheet metal to its intended position and improving the positioning accuracy and stability of the device.

[0108] As an optional embodiment, the inner limiting component includes:

[0109] Two limiting rods 609 are symmetrically arranged with the positioning seat 505 as the center, and the limiting rods 609 are slidably connected inside the positioning seat 505.

[0110] Two L-shaped plates 611 are symmetrically arranged with the positioning seat 505 as the center. One side of the L-shaped plate 611 is fixedly connected to one end of the limiting rod 609, and the top side of the L-shaped plate 611 is slidably connected to the outer periphery of the fixed shaft 603 through the third through hole.

[0111] The third spring 610 is sleeved on the outer periphery of the limiting rod 609, and the two sides of the third spring 610 are fixedly connected to the L-shaped plate 611 and the inner wall of the positioning seat 505, respectively.

[0112] During the process of fixing the positioning seat 505, the second limiting plate 606 will compress the limiting rod 609 and the third spring 610, causing the limiting rod 609 to drive the L-shaped plate 611 and the first chuck 612 to move towards the second chuck 613. Through the cooperation of the second chuck 613 and the first chuck 612, the positions of the connecting shaft 506, the arc-shaped seat 507 and the fixed seat 510 are limited and constrained. The limiting and fixing between the positioning seat 505 and the fixed seat 510 ensures the stability of the plate and the communication antenna, preventing them from moving during subsequent movement and welding, thereby ensuring the high-precision positioning effect and welding quality of the device.

[0113] As an optional embodiment, the parallel positioning component 7 includes:

[0114] The electric push rod 701 is fixed to the bottom side inside the worktable 1, and the electric push rod 701 is located directly below the first through hole 3;

[0115] A conical block 702 is fixedly connected to the top of the electric push rod 701, and the cross-sectional shape of the conical block 702 is set to a cross shape;

[0116] Multiple connecting blocks 704 are arranged in a circular array inside the limiting seat 501, and the top of the connecting blocks 704 is fixedly connected to the bottom of the positioning seat 505.

[0117] Multiple second cone blocks 703 are arranged in a circumferential array inside the limiting seat 501, and the top of the second cone block 703 is fixedly connected to the bottom of the connecting block 704. Both the second cone block 703 and the connecting block 704 are located inside the second through hole 503.

[0118] The electric push rod 701 drives the conical block 702 to move vertically upwards. The conical block 702 gradually enters the first through hole 3 and the second through hole 503. As the conical block 702 continues to move upwards, it gradually contacts the multiple second conical blocks 703 of the top circular shaft array. These second conical blocks 703, through multiple connecting blocks 704, drive multiple positioning seats 505 and fixing seats 510 to move synchronously away from the center of the limiting seat 501. This allows external machinery or personnel to sequentially place the sheet metal to be welded and the communication antenna onto the multiple positioning seats 505 and... Between the fixed seats 510, this device uses a single electric push rod 701 to drive the central conical block 702 to move vertically. Through the conical surface cooperation of the conical block 702 and the second conical block 703, the vertical movement is converted into the radial movement of multiple circumferentially distributed second conical blocks 703, realizing the synchronous radial expansion and contraction of multiple positioning seats 505 and fixed seats 510. This design realizes the rapid and automatic opening and closing of the tooling, provides a clear operating space for the central area, significantly improves the convenience and efficiency of loading and unloading of sheet metal and communication antennas, and helps to reduce the adverse effects on sheet metal and communication antennas during loading and unloading.

[0119] As an optional embodiment, the rotating unit includes:

[0120] The first motor 4 is fixed inside the bottom side of the workbench 1, and the top of the output shaft of the first motor 4 is fixedly connected to a round shaft, and the top of the round shaft is fixedly connected to the bottom of the rotating disk 2.

[0121] The operating unit includes:

[0122] The control panel is fixed to the top of the workbench 1 and is located on one side of the rotating disk 2;

[0123] The first motor 4 drives the circular shaft and rotating disk 2 to rotate, moving the sheet metal and communication antenna directly below the external automatic welding unit. The external automatic welding unit will then perform welding on the sheet metal and communication antenna. After welding is completed, the first motor 4 continues to drive the circular shaft and rotating disk 2 to rotate. When it moves directly above the electric push rod 701, the second motor 608 first drives the cam 604 and the ring gear 601 to reset. Then, the electric push rod 701 drives the conical block 702 and the second conical block 703 to move upward, quickly releasing the positioning seat 505 and the fixed seat 510 from fixing the welded sheet metal and communication antenna, so that they can be unloaded, thereby ensuring the overall performance of the device.

[0124] The working principle of this invention is as follows: First, the device is placed in a suitable position. Then, the external automatic welding unit is installed in a suitable position on the top of the workbench 1 and set on the side away from the electric push rod 701. According to actual needs, the electric push rod 701 drives the conical block 702 to move vertically upward. The conical block 702 will gradually enter the first through hole 3 and the second through hole 503. As the conical block 702 moves upward, it will gradually contact the multiple second conical blocks 703 of the top circular shaft array in sync. The multiple second conical blocks 703 will drive the multiple positioning seats 505 and fixed seats 510 to move synchronously away from the center of the limiting seat 501 through the multiple connecting blocks 704. This allows external machinery or workers to place the plate to be welded and the communication antenna between the multiple positioning seats 505 and the fixed seats 510 in sequence.

[0125] After the sheet metal and communication antenna are placed, the first spring 504 will drive the positioning seat 505, connecting shaft 506, arc seat 507, cavity 508, sealing sliding member 509 and fixing seat 510 to move synchronously towards the sheet metal and communication antenna, so that the positioning seat 505 contacts and fixes itself on different outer surfaces of the sheet metal. Gas is delivered to one side of the cavity 508 through an external gas supply device, connecting pipe and pipeline, so that the pressure on one side increases. When the pressure overcomes the initial preload of the fourth spring, the sealing sliding member 509 will drive the fixing seat 510 to make a linear micro-position movement in the direction of the communication antenna, so that the welding angle of the communication antenna can be precisely adjusted. At the same time, through the hinged connecting shaft 506 and arc seat 507, the fixing seat 510 can fit well with the surface of the communication antenna with different curves.

[0126] After securing the sheet metal and communication antenna, the second motor 608 is activated. This motor drives one of the fixed shafts 603, gears 602, and cams 604 to rotate. Utilizing the linkage between gears 602 and the ring gear 601, power is transmitted to the ring gear 601, causing it to drive multiple other gears 602, fixed shafts 603, and cams 604 to rotate. During rotation, the cam presses against a second limiting plate 606 on one side. Simultaneously, the ring gear 601 drives multiple first limiting plates 605, which are fixed to it, to move synchronously, thus pressing against the other side... When the second limiting plate 606 is pressed, the two second limiting plates 606 can move synchronously towards the positioning seat 505, radially clamping and fixing the position of the positioning seat 505 to fix the position of the sheet material. During the process of fixing the positioning seat 505, the second limiting plate 606 will press the limiting rod 609 and the third spring 610, causing the limiting rod 609 to drive the L-shaped plate 611 and the first chuck 612 to move towards the second chuck 613. Through the cooperation of the second chuck 613 and the first chuck 612, the position of the connecting shaft 506, the arc-shaped seat 507 and the fixed seat 510 is limited and constrained.

[0127] The first motor 4 drives the circular shaft and rotating disk 2 to rotate, moving the sheet metal and communication antenna directly below the external automatic welding unit. The external automatic welding unit will then perform welding on the sheet metal and communication antenna. After welding is completed, the first motor 4 continues to drive the circular shaft and rotating disk 2 to rotate. When it moves directly above the electric push rod 701, the second motor 608 first drives the cam 604 and the ring gear 601 to reset. Then, the electric push rod 701 drives the conical block 702 and the second conical block 703 to move upward, quickly releasing the positioning seat 505 and the fixed seat 510 from fixing the welded sheet metal and communication antenna, so that they can be unloaded, thereby ensuring the overall performance of the device.
