Description

Technical Field

[0001] This utility model relates to the field of high-frequency welding machine technology, and in particular to a high-frequency welding machine for temperature control elements. Background Technology

[0002] A high-frequency welding machine is a welding device that utilizes the skin effect and proximity effect of high-frequency current to heat and melt the metal workpiece itself, and achieve metallurgical bonding under pressure.

[0003] Existing temperature control element welding methods involve placing the workpiece between two electrodes, pressing it against the electrodes, and then applying a high-frequency current to melt the weld surface. However, this process is inconvenient; workpieces can only be removed after the previous workpiece has been welded and the weld surface has cooled and solidified. New workpieces must then be placed between the electrodes for subsequent welding. Furthermore, the welding process generates harmful fumes that can easily disperse into the working environment, posing a health risk to workers and resulting in poor performance. Therefore, we propose a high-frequency welding machine for temperature control elements. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-4 A high-frequency welding machine for temperature control elements includes a base 1, with several support legs 14 installed on the bottom edge of the base 1, and a control cabinet 24 installed on one side of the bottom of the base 1. The control cabinet 24 contains a controller, which is either a control motherboard or a PLC logic controller.

[0020] like Figure 1 and Figure 2 As shown, a rotating shaft 23 is rotatably connected to the top of the base 1, and a rotating platform 2 is mounted on the top of the rotating shaft 23. The bottom of the rotating shaft 23 passes through the base 1 and is connected to the drive motor 22. A fixing plate 21 is connected to the bottom of the base 1 through a connecting rod. The drive motor 22 is fixed to the bottom of the fixing plate 21. In actual use, the drive motor 22 can drive the rotating shaft 23 to rotate, and then drive the rotating platform 2 to rotate as needed.

[0021] like Figure 2 As shown, an angle sensor 20 is installed on the side of the rotating shaft 23. The angle sensor 20 is connected to the controller through a wire. The rotation angle of the rotating shaft 23 can be controlled by the angle sensor 20, so that the rotating shaft 23 can rotate to a preset angle as needed.

[0022] like Figure 1 Several lower electrodes 30 are mounted on the top of the rotary table 2. A conductive slip ring 17 is coaxially mounted on the side of the rotating shaft 23. The inner ring of the conductive slip ring 17 is mounted on the rotating shaft 23 and is connected to several lower electrodes 30 by wires. The outer ring of the conductive slip ring 17 is mounted on the top of the base 1 and is connected to the controller by wires. In actual use, the conductive slip ring 17 can supply power to the lower electrodes 30 during the rotation of the rotary table 2, so that the lower electrodes 30 are powered normally during use.

[0023] A mounting bracket 9 is installed on one side of the base 1. The top of the mounting bracket 9 is L-shaped and extends above the rotary table 2. A mounting plate 27 is located below the top of the mounting bracket 9. The top of the mounting plate 27 is connected to the top of the mounting bracket 9 via a telescopic mechanism 5. An upper electrode 26 is installed at the bottom of the mounting plate 27. The upper electrode 26 is located above the lower electrode 30 and is connected to the controller via a wire. The telescopic mechanism 5 is one of an electric push rod, a cylinder, or a hydraulic rod, and is connected to the controller via a wire. In actual use, the operator can place the workpiece to be welded on the lower electrode 30 and then push the mounting plate 27 to move through the telescopic mechanism 5. The mounting plate 27 drives the upper electrode 26 to move down, so that the upper electrode 26 abuts against the top of the workpiece to be welded. At this time, a circuit is formed between the lower electrode 30, the workpiece to be welded, and the upper electrode 26. The current heats and melts the contact surface of the workpiece to be welded, thus completing the welding.

[0024] It should be noted that the top of the rotary table 2 is coaxially mounted with a first annular plate 4 and a second annular plate 13, and several partitions 3 are installed between the first annular plate 4 and the second annular plate 13. The partitions 3 form welding grooves with the first annular plate 4 and the second annular plate 13. The lower electrodes 30 are all located in the corresponding welding grooves. The lower electrodes 30 can be separated by the partitions 3, the first annular plate 4 and the second annular plate 13, so that they will not cause any obstruction during processing.

[0025] like Figure 1 and Figure 4 As shown, a negative pressure pump 7 is installed on the top of the mounting bracket 9. The negative pressure pump 7 is connected to the controller via a wire. An air intake pipe 8 is connected to the air inlet of the negative pressure pump 7. A filter canister 11 is connected to one side of the mounting bracket 9 via a fixing bracket 19. A canister lid 10 is installed on the top of the filter canister 11. One end of the air intake pipe 8 is fixed to the top of the canister lid 10. A filter element 29 is coaxially installed inside the filter canister 11. The top of the filter element 29 is sealed to the bottom of the canister lid 10, and the end of the air intake pipe 8 passes through the canister lid 10 and communicates with the inside of the filter element 29. In actual use, the air inside the filter canister 11 can be filtered by the filter element 29 and discharged into the external environment through the air intake pipe 8 via the negative pressure pump 7.

[0026] like Figure 3 and Figure 4 As shown, an annular tube 18 is coaxially connected to the top edge of the mounting plate 27. One side of the annular tube 18 is connected to the side of the filter barrel 11 through the air supply pipe 12. Several adsorption heads 28 are installed at the bottom of the annular tube 18. The bottom ends of the adsorption heads 28 all penetrate the mounting plate 27. There is a gap between the side wall of the filter element 29 and the inner wall of the filter barrel 11. In actual use, the adsorption heads 28 will move with the lifting and lowering of the mounting plate 27. During the welding process, when the negative pressure pump 7 sucks out the gas in the filter barrel 11, it will cause a negative pressure to be generated in the filter barrel 11. Then, the adsorption heads 28 can generate suction through the air supply pipe 12 and the annular tube 18 to adsorb the harmful fumes generated during welding and transport them into the filter barrel 11. The fumes are filtered by the filter element 29 to remove the harmful dust in the fumes. The clean air is transported to the negative pressure pump 7 through the air intake pipe 8 and finally discharged into the external environment.

[0027] like Figure 3 and Figure 4 As shown, the adsorption heads 28 are all tilted, with the bottom of the adsorption head 28 facing downwards from the upper electrode 26. This way, the harmful fumes generated during welding will be completely absorbed by the adsorption head 28 and will not drift into the surrounding environment.

[0028] Specifically, during the use of this utility model, the operator places the workpiece to be welded on the corresponding lower electrode 30, and then controls the drive motor 22 to work through the controller. The drive motor 22 drives the rotating shaft 23 to rotate, and the rotating shaft 23 drives the rotating table 2 to rotate. The rotating table 2 rotates the workpiece to be welded on the lower electrode 30 to below the upper electrode 26. At this time, after the angle sensor 20 detects that the rotation angle of the rotating shaft 23 has reached the preset value, it transmits the data to the controller, and the controller shuts down the drive motor 22. Afterwards, the controller controls the extension mechanism 5 to extend, pushing the mounting plate 27 to move down. The mounting plate 27 drives the upper electrode 26 to move down, so that the bottom of the upper electrode 26 contacts the top of the workpiece to be welded. At this time, a circuit is formed between the upper electrode 26, the workpiece to be welded and the lower electrode 30. When the high-frequency current flows through the workpiece to be welded, it will heat the welding surface of the workpiece to be welded, so that the welding surfaces of the workpiece to be welded are welded together, and the welding is completed. After welding is completed, the operator can control the telescopic mechanism 5 to retract via the controller. The mounting plate 27 will then cause the upper electrode 26 to detach from the workpiece. Afterward, the controller will control the drive motor 22 to work. The drive motor 22 will drive the rotary table 2 to rotate via the rotating shaft 23, moving the completed workpiece away from under the upper electrode 26. At the same time, the unwelded workpiece will move to under the upper electrode 26 for welding. During the welding process, the previously completed workpiece can be allowed to cool naturally. After cooling, the operator will remove the workpiece and place the new workpiece on the corresponding lower electrode 30.

[0029] Furthermore, such as Figure 1 and Figure 2 As shown, the bottom of the rotary table 2 is equipped with several support blocks 16. An annular groove 15 is provided on the top edge of the base 1. The bottom of each support block 16 extends into the corresponding annular groove 15, and the bottom of the support block 16 is connected to the bottom of the annular groove 15 by ball bearings. Through the cooperation between the support block 16 and the annular groove 15, the rotary table 2 can be supported, so that the rotary table 2 remains stable.

[0030] Furthermore, such as Figure 1 and Figure 3 As shown, at least one guide rod 6 is installed on the top of the mounting plate 27. The top of the guide rod 6 slides through the mounting frame 9. The guide rod 6 can guide and limit the mounting plate 27, so that the mounting plate 27 remains stable when moving.

[0031] Furthermore, such as Figure 2 and Figure 3 As shown, a pipe support frame 25 is installed on one side of the mounting frame 9. The gas supply pipe 12 is connected to the mounting frame 9 through the pipe support frame 25. The pipe support frame 25 can support the gas supply pipe 12 so that during the welding process, the gas supply pipe 12 will not come into contact with the upper electrode 26, the workpiece to be welded, and the lower electrode 30, thus avoiding damage to the gas supply pipe 12 caused by the high temperature generated during the welding process.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
