Description

Technical Field

[0001] The present invention relates to the field of laser welding, and in particular to a welding device for antenna production. Background Art

[0002] Antenna elements are components of an antenna that guide and amplify electromagnetic waves, making the electromagnetic signals received by the antenna stronger. Antenna elements come in a variety of shapes, including rods, squares (the type discussed in this application), and other irregular shapes.

[0003] Laser welding is a high-precision welding technology with the advantages of fast welding speed and high precision. Therefore, it is particularly suitable for the processing and production of antennas and other electronic components.

[0004] The antenna vibrator is one of the core components of the antenna. The antenna vibrator is generally welded and fixed separately through the four corners. The implementation of laser welding of antenna vibrators has high process requirements and restrictions. For example, it cannot handle thicker workpieces. For the welding base material, it is required to have a good absorption rate of the laser heat energy and high temperature resistance. For example, in some existing technologies, such as patent document CN103367869B, an antenna processing method is proposed. Although it overcomes the problem of adaptability of the workpiece material to laser welding, the implementation of this method has not yet completely overcome the above-mentioned technical challenges.

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0055] like Figures 1 to 6 As shown, an antenna welding device includes: a frame 1, a base 10, and a laser welder 19. The frame 1 is arranged above the base 10, and the laser welder 19 is slidably connected to the bottom surface of the frame 1 for laser welding the antenna element 38 of the antenna.

[0056] The antenna vibrator 38 includes a substrate and at least two pairs of symmetrically arranged welding reinforcement plates 16. The substrate is provided with a through transverse groove for the welding reinforcement plate 16 to pass through. The welding reinforcement plate 16 is L-shaped before processing. The carrier plate 15 is provided with a groove for engaging the welding reinforcement plate 16. The substrate is mounted on the carrier plate 15. A thinning mechanism for grinding and thinning the welding reinforcement plate 16 is arranged on the frame 2. A rolling brush 37 mechanism for rolling a brush 37 on the welding reinforcement plate 16 to enhance the laser absorption rate is arranged on the frame 3. A stamping mechanism for stamping the welding reinforcement plate 16 so that the welding reinforcement plate 16 is bent and fixed on the substrate is installed on the frame 4. In general, in an embodiment of the present invention, the antenna vibrator 38 is laser welded by the following process.

[0057] First, the welding reinforcement plate 16 can be placed on the carrier plate 15. Specifically, the carrier plate 15 can have a groove for engaging the welding reinforcement plate 16, or other pin hole structures, to relatively fix the welding reinforcement plate 16 so that it will not be displaced when the antenna vibrator 38 is placed. The material of the welding reinforcement plate 16 is preferably a material that is resistant to high temperatures and has good conductivity, such as an aluminum alloy. Ultimately, the welding reinforcement plate 16 needs to serve as a connection point for laser welding, rather than directly welding the antenna vibrator 38 itself. The welding reinforcement plate 16 is made of a material that is more conducive to laser welding, so that the subsequent laser welding process is smoother. Subsequently, we place the antenna vibrator 38 on the welding reinforcement plate 16. Of course, a transverse groove corresponding to the welding reinforcement plate 16 is provided on the cross section of the antenna vibrator 38. The welding reinforcement plate 16 passes through the transverse groove and is exposed on the upward end face of the antenna vibrator 38.

[0058] In order to make laser welding easier to advance, the welding reinforcement plate 16 is further pretreated. First, the thinning mechanism can be used to reduce the overall thickness of the welding reinforcement plate 16. This makes the thickness of the two welding targets relatively reduced, which is beneficial to the quality of the laser welding weld. Secondly, the surface roughness after reduction can be appropriately amplified to make the surface rougher. In a more specific pretreatment step, carbon black, graphite particles, etc. can also be sprayed or rolled 37 thereon to increase the welding surface's absorption efficiency for the energy released by the laser. In this embodiment, a rolling brush 37 mechanism is used to perform rolling brush 37. However, these dry, particulate materials cannot effectively adhere to the surface of the welding reinforcement plate 16. In particular, a protective gas needs to be applied in the subsequent welding process, that is, a helium or argon gas source is sprayed around the welding working surface, which exacerbates the problem of loose carbon black adhesion.

[0059] In this embodiment, a stamping mechanism is also provided. As for the L-shaped welding reinforcement plate 16, it is obvious that it has not yet been fully fixed to the vibrator 38 itself. The stamping mechanism is used to bend the L-shaped welding reinforcement plate 16 into a U-shape or C-shape. The two ends of the horizontal groove are tightly attached to the upper and lower end surfaces of the vibrator 38, thereby achieving low-cost and efficient fixation between the vibrator 38 and the welding reinforcement plate 16. In addition, the surface roughness of the pressure head of the stamping mechanism is as small as possible, so that the carbon black or graphite originally floating on the surface of the welding reinforcement plate 16 is tightly embedded in the welding reinforcement plate 16, optimizing the problem of surface coating loss before welding is carried out during the execution of laser welding.

[0060] After the above processing is completed, the target workpiece can be placed and the joint can be laser welded using the laser welder 19. A dedicated clamper or a multi-degree-of-freedom manipulator can be set on the frame 1 to drive the laser welder 19, and its specific structure will not be repeated in this embodiment.

[0061] Frame 5 5 is provided on one side of Frame 1. A limit plate 7 is slidably connected to Frame 5 5. The limit plate 7 is provided with a through-going transverse groove. The number and shape of the transverse grooves correspond to the number and shape of the welding reinforcement plates 16. When the limit plate 7 covers the base plate and the welding reinforcement plates 16, the beam from the laser welder 19 can pass through the transverse grooves and reach the welding reinforcement plates 16 and the connection between them and the workpiece being welded. A container 6 for storing protective gas is fixedly mounted on Frame 5 5. The inner wall of the transverse groove is provided with a plurality of air holes. An air supply channel is provided within the limit plate 7, one end of which is connected to the container 6. The air holes are connected to the air supply channel.

[0062] During the laser welding process, higher temperatures will be generated in local areas, which may affect the quality of the weld for materials with large thermal deformation. Therefore, this embodiment aims to solve this problem. Specifically, by inverting or moving the limiting plate 7 and covering it above the welding reinforcement plate 16, the welding reinforcement plate 16 is pressed and fixed, and a transverse groove is provided at the same time so that the welding area of ​​the welding reinforcement plate 16 is exposed. Alternatively, a highly transparent material is selected for the limiting plate 7 as a whole or in the transverse groove portion, so that the laser can be injected into the weld with low attenuation to perform laser welding. In short, the limiting plate 7 is used to implement compression or limiting in the direction of the upper and lower end faces, to avoid deformation such as warping and bending of the material at the weld to a certain extent.

[0063] More specifically, the limiting plate 7 can also serve as a tool for releasing the shielding gas. Since the transverse groove is semi-enclosed (applying a transparent material on the transverse groove further improves the sealing, but will affect the heat dissipation to a certain extent), releasing the shielding gas in this environment relatively reduces the diffusion of the shielding gas and the degree of interference from the outside air.

[0064] The base 10 is provided with a horizontal slide rail, and the carrier plate 15 is slidably connected to the slide rail. The base 10 is rotatably connected to a horizontal screw rod 14, which passes through the carrier plate 15 and is threadedly connected to the carrier plate 15. The end of the screw rod 14 close to the frame 1 is coaxially fixedly connected to a fixed shaft 30, and one end of the fixed shaft 30 is fitted with a rotating shaft 11. The rotating shaft 11 is provided with a cross slot, and one end of the fixed shaft 30 is fixedly installed with a cross pin, and the cross pin slides with the cross slot. The rotating shaft 11 close to the screw rod 14 is fixedly installed with a slide plate 29, and the slide plate 29 is slidably connected to the upper end surface of the base 10. The rotating shaft 11 is provided with a fixed plate 28 on the side away from the screw rod 14. The fixed plate 28 is fixedly connected to the base 10, and an elastic member is provided between the slide plate 29 and the fixed plate 28. The end of the rotating shaft 11 away from the screw 14 passes through the fixed plate 28 and extends outward. The end of the rotating shaft 11 away from the screw 14 is fixedly mounted with a gear 4 21. A horizontal rack 31 is fixedly mounted on the side wall of the limiting plate 7, and a gear 1 25 is rotatably connected to the machine base 5, and the rack 31 is engaged with the gear 1 25. A pulley 2 23 is rotatably connected to the machine frame 5, and a pulley 1 24 is coaxially fixedly mounted on the gear 1 25. The pulley 1 24 is connected to the pulley 2 23 through a transmission belt 20. A gear 5 22 is coaxially fixedly mounted on the pulley 2 23, and the gear 4 21 corresponds to the gear 5 22.

[0065] This embodiment provides a method for driving the limit plate 7. Specifically, the screw 14 rotates to drive the carrier plate 15, along with the welded reinforcement plate 16 and vibrator 38, along the base 10. When the carrier plate 15 reaches the end of the base 10, below the frame 1, it gradually moves onto the fixed shaft 30. During this process, the carrier plate 15 compresses and pushes the slide plate 29. The slide plate 29 drives the rotating shaft 11 away from the fixed shaft 30, but its cross pin remains in the cross slot, allowing torque on the fixed shaft 30 to be transmitted to the rotating shaft 11.

[0066] At the extreme position, the carrier's threaded hole is completely disengaged from screw 14, and shaft 11 slides outward, causing gear 4 21 to mesh with gear 5 22. Shaft 11 drives gears 4 21 and 5 22, which in turn rotate pulley 23. Pulley 23, via belt 20, drives pulley 1 24 and gear 1 25 on it. These gears drive rack 31, which in turn drives limit plate 7 toward the welded reinforcement plate 16 and antenna element 38 below frame 1, until it covers the desired position. This completes the automatic placement of limit plate 7, achieving a high degree of automation.

[0067] The thinning mechanism includes a driver 1 8, a rotating shaft 2 12, a mounting plate 9, and two rotating cutters 36. The driver 1 8 is slidably connected to the frame 2 2 and is used to drive the rotating shaft 2 12 to rotate. The mounting plate 9 is mounted on the driver 1 8. The rotating shaft 2 12 passes through the mounting plate 9 and is rotatably connected to the mounting plate 9. Sprocket 1 and sprocket 2 are rotatably connected to the mounting plate 9. Sprocket 3 is coaxially fixedly mounted on the rotating shaft 2 12. The sprockets 1, 2, and 3 are connected via a transmission chain. The two rotating cutters 36 are coaxially fixedly connected to sprocket 1 and sprocket 2, respectively.

[0068] The driver 1 8 can be a motor, which drives the rotating shaft 2 12 and simultaneously drives one or more rotating tools 36 on both sides to rotate, thereby appropriately thinning the welding part of the welding reinforcement plate 16.

[0069] The roller brush 37 mechanism includes a barrel and multiple horizontally arranged roller brushes 37. The barrel is positioned above the base 10 and has multiple discharge ports, the number of which corresponds to the number of welded reinforcement plates 16. A roller brush 37 is positioned in each discharge port. The roller brush 37 is positioned directly above each welded reinforcement plate 16. The barrel 17 is slidably connected to the frame 3 3.

[0070] The barrel 17 is filled with carbon black or graphite particles. During operation, the barrel 17 moves downward, so that the roller brush 37 contacts the welding reinforcement plate 16 to carry out material feeding and roller brush 37 .

[0071] A bevel gear 1 35 is fixedly mounted on the second rotating shaft 12. A horizontally arranged rotating shaft 3 13 is rotatably connected to the outer wall of the barrel. A sprocket 4 33 is fixedly mounted on one end of the rotating shaft 3 13. A gear 2 26 is fixedly mounted on the other end of the rotating shaft 3 13. An extension plate 32 is fixedly mounted on the outer wall of the barrel 17. The lower end of the extension plate 32 is rotatably connected to gear 3 27 and bevel gear 2. Bevel gear 1 35 corresponds to bevel gear 2. Gear 3 27 is coaxially fixedly mounted on bevel gear 2, and meshes with gear 2 26. Sprocket 5 34 is coaxially fixedly mounted on the roller brush 37. Sprocket 4 33 and each sprocket 5 34 are connected via a transmission chain. A connecting rod is provided between the barrel 17 and the driver 1 8. One end of the connecting rod is hinged to the side wall of the barrel 17. The other end of the connecting rod is hinged to the outer wall of the driver 1 8.

[0072] This embodiment proposes a structure and method combining thinning with a roller brush 37 . Specifically, the thinning process is the same as in the previous embodiment. Driver 1 8 rotates shaft 2 12 , driving sprockets 1 and 2 on either side, which in turn drives rotary cutter 36 to simultaneously thin weld reinforcement plate 16 .

[0073] Regarding the roller brush 37 mechanism, bevel gear 2 is located between the mounting plate 9 and bevel gear 1 35. After thinning is complete, driver 1 8 is moved to retract bevel gear 1 35 toward the mounting plate 9. Driver 1 8 also drives the connecting rod, causing the barrel 17 to move downward, and bevel gear 2 to follow. In short, bevel gear 1 35 and bevel gear 2 move closer and closer until the roller brush 37 contacts the target weld reinforcement plate 16, and bevel gear 1 35 and bevel gear 2 are meshed.

[0074] At this time, the second rotating shaft 12 is driven, which drives the first bevel gear 35 and the second bevel gear to rotate, and drives the third gear 27 to rotate synchronously, which in turn drives the second gear 26 and the third rotating shaft 13 thereon to rotate, drives the fourth sprocket 33 to rotate, and finally drives the roller brush 37 to rotate. Through the above process, the power source of the driver 1 8 is engaged with the roller brush 37 mechanism at the same time as the workstation is switched after the thinning is completed, reducing the cost of the power source and eliminating the need for an additional controller for switching and control.

[0075] The realization of the precise meshing of the bevel gear 1 35 and the bevel gear 2 depends on the transmission ratio of each component and the proportional relationship of the size of each component, which is designed based on the geometric and mechanical knowledge known in the art and will not be described in detail in this embodiment.
