Description

Technical Field

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

[0002] The antenna vibrator is a component on the antenna that guides and amplifies electromagnetic waves, making the electromagnetic signal received by the antenna stronger. The antenna vibrator has various shapes, some are rod-shaped, some are square (this application discusses this type) or 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 other electronic components such as antennas.

[0004] The antenna vibrator is one of the core components of the antenna. The welding of the antenna vibrator is generally carried out by welding and fixing the four corners separately. The implementation of laser welding of the antenna vibrator has high process requirements and restrictions. For example, it cannot cope with thicker workpieces. For the welding substrate, it is required to have a good absorption rate of the laser heat energy and high temperature resistance. For another example, in some prior arts, such as patent document CN103367869B, a method for processing antennas is proposed.

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the 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 creative work are 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 vibrator 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 2. A rolling brush 37 mechanism for rolling a material used to enhance the laser absorption rate on the welding reinforcement plate 16 is arranged on the frame 3 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 4. In general, in the 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 be used as a connection point for laser welding, rather than directly welding the antenna vibrator 38 itself. The welding reinforcement plate 16 uses 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 opened 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 enlarged 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 absorption efficiency of the welding surface for the laser released energy. 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, it is necessary to apply a protective gas in the subsequent welding process, that is, a helium or argon gas source is sprayed around the welding work surface, which exacerbates the problem of loose adhesion of carbon black.

[0059] In this embodiment, a stamping mechanism is also provided. As for the L-shaped welding reinforcement plate 16, it is obviously not yet fully fixed to the vibrator 38 itself. The stamping mechanism is used to bend and fold the L-shaped welding reinforcement plate 16 into a U-shape or a C-shape. The two ends of the horizontal groove are tightly attached to the upper and lower end surfaces of the vibrator 38, thereby realizing 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, which optimizes the problem of surface paint 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 a 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] A frame 5 5 is provided on one side of the frame 1, and a limit plate 7 is slidably connected to the frame 5 5. The limit plate 7 is provided with a through transverse groove, and the number and shape of the transverse grooves correspond to the number and shape of the welding reinforcement plate 16. When the limit plate 7 covers the substrate and the welding reinforcement plate 16, the light beam of the laser welder 19 can pass through the transverse groove to reach the welding reinforcement plate 16 and the connection between the welding reinforcement plate 16 and the welded workpiece. A container 6 for storing protective gas is fixedly installed on the frame 5 5, and a plurality of air holes are provided on the inner wall of the transverse groove. A gas supply channel is provided inside the limit plate 7, and one end of the gas supply channel is connected to the container 6. The air holes are connected to the gas 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, the present embodiment aims to solve this problem. Specifically, the welding reinforcement plate 16 is pressed and fixed by inverting or moving the limit plate 7 and covering it above the welding reinforcement plate 16, and a transverse groove is provided at the same time to expose the welding area of ​​the welding reinforcement plate 16. Alternatively, a highly transparent material is selected for the limit plate 7 in the entire or transverse groove portion, so that the laser can be injected into the welding point under the premise of low attenuation to perform laser welding. In short, the limit plate 7 is used to implement compression or limiting in the direction of the upper and lower end faces, so as to avoid deformation such as warping and bending of the material at the welding point to a certain extent.

[0063] More specifically, the limiting plate 7 can also be used as a tool for releasing the protective gas. Since the transverse groove is half-enclosed (the transparent material applied on the transverse groove further improves the sealing property, but will affect the heat dissipation to a certain extent), releasing the protective gas in this environment relatively reduces the diffusion of the protective gas and reduces 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 with a horizontal screw rod 14, and the screw rod 14 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 with a fixed shaft 30, and one end of the fixed shaft 30 is sleeved with a rotating shaft 11, and a cross groove is provided on the rotating shaft 11. A cross pin is fixedly installed at one end of the fixed shaft 30, and the cross pin is slidably matched with the cross groove. A slide plate 29 is fixedly installed on the side of the rotating shaft 11 close to the screw rod 14, and the slide plate 29 is slidably connected to the upper end surface of the base 10. A fixed plate 28 is provided on the side of the rotating shaft 11 away from the screw rod 14, and 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 rod 14 passes through the fixing plate 28 and extends outward. A gear 4 21 is fixedly mounted on the end of the rotating shaft 11 away from the screw rod 14. 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 base 5, and the rack 31 meshes with the gear 1 25. A pulley 2 23 is rotatably connected to the frame 5 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] In this embodiment, a driving method of the limit plate 7 is provided. Specifically, the carrier plate 15 and the welded reinforcing plate 16 and the vibrator 38 thereon are driven to move along the base 10 by the screw rod 14. When the carrier plate 15 moves to the end of the base 10, that is, below the frame 1, the carrier plate 15 gradually moves to the fixed shaft 30. During this process, the carrier plate 15 squeezes and pushes the slide plate 29. The slide plate 29 drives the rotating shaft 11 thereon away from the fixed shaft 30, but its cross pin is always located in the cross groove, and the torque on the fixed shaft 30 can be transmitted to the rotating shaft 11.

[0066] At the extreme position, the threaded hole of the carrier is completely disengaged from the screw rod 14, and the shaft 11 slides outward, causing the gear 4 21 to mesh with the gear 5 22. The shaft 11 drives the gear 4 21 and the gear 5 22 to rotate, thereby driving the pulley 2 23 to rotate, and the pulley 2 23 drives the pulley 1 24 through the transmission belt 20, and the gear 1 25 thereon to rotate, and the gear drives the rack 31, driving the limit plate 7 to slide toward the welding reinforcement plate 16 and the antenna vibrator 38 below the frame 1 until the expected position is covered, thus completing the automatic arrangement of the limit plate 7, with a good 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, and sprocket 3 is coaxially fixedly installed on the rotating shaft 2 12. The sprocket 1, sprocket 2 and sprocket 3 are connected by 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 a plurality of horizontally arranged roller brushes 37, the barrel is arranged above the base 10, and the barrel is provided with a plurality of discharge ports, the number of which corresponds to the number of the welded reinforcing plates 16. The roller brush 37 is arranged in each of the discharge ports. The roller brush 37 is arranged just above each welded reinforcing 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 reinforcing plate 16 to feed the material and the roller brush 37 .

[0071] A bevel gear 1 35 is fixedly mounted on the rotating shaft 2 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, and a gear 3 27 and a bevel gear 2 are rotatably connected at the lower end of the extension plate 32. The bevel gear 1 35 corresponds to the bevel gear 2. A gear 3 27 is coaxially fixedly mounted on the bevel gear 2, and the gear 3 27 is meshed with the gear 2 26. A sprocket 5 34 is coaxially fixedly mounted on the roller brush 37. The sprocket 4 33 and each sprocket 5 34 are connected by a transmission chain. A connecting rod is provided between the barrel 17 and the driver 1 8, and 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] In this embodiment, a working structure and working method combining thinning with a rolling brush 37 are proposed. Specifically, the thinning is the same as the above embodiment. The driver 1 8 drives the rotating shaft 2 12 to rotate, driving the sprocket 1 and the sprocket 2 on both sides to rotate, and then drives the rotating tool 36 to synchronously thin the welding reinforcement plate 16.

[0073] For the roller brush 37 mechanism, the bevel gear 2 thereon is located between the mounting plate 9 and the bevel gear 1 35. After the thinning is completed, on the one hand, the driver 1 8 needs to be moved so that the bevel gear 1 35 retreats toward the mounting plate 9. On the other hand, at this time, the driver 1 8 drives the connecting rod to move the barrel 17 downward, and the bevel gear 2 also moves downward accordingly. In short, the bevel gear 1 35 and the bevel gear 2 get closer and closer until the roller brush 37 fits the target welding reinforcement plate 16, and the bevel gear 1 35 and the bevel gear 2 are meshed.

[0074] At this time, the rotating shaft 2 12 is driven to drive the bevel gear 1 35 and the bevel gear 2 to rotate, and the gear 3 27 is driven to rotate synchronously, which in turn drives the gear 2 26 and the rotating shaft 3 13 thereon to rotate, drives the sprocket 4 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, which reduces the cost of the power source and does not require an additional controller for switching and control.

[0075] The realization of the exact 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.
