Description

Technical Field

[0001] The utility model relates to the technical field of capacitor spot welding, in particular to a capacitor spot welding processing device. Background Art

[0002] Capacitor spot welding is a welding method that uses the charge and discharge characteristics of capacitors. During the welding process, the capacitor is charged and stores electrical energy, and then releases the stored electrical energy in a very short time to form a high current density welding current. This high current density welding current can quickly heat and melt the welding material, thereby achieving welding;

[0003] The existing capacitor spot welding method often involves workers holding a welding gun to spot weld the workpiece. Although this method can meet basic welding needs, it has problems such as low welding efficiency and unstable welding quality, and is prone to burn accidents. First of all, the efficiency of spot welding by workers holding a welding gun is low. Since this method relies on the workers' operating skills and experience, the welding speed and quality are often affected by human factors, resulting in low production efficiency. In addition, long-term handheld operation can easily make workers feel tired, further affecting the welding quality.

[0004] Secondly, the instability of welding quality is also a problem that needs to be solved urgently. The spot welding method of handheld welding guns is difficult to ensure the consistency of parameters every time welding, such as welding time, current size, etc. Changes in these factors will directly affect the welding quality. Therefore, even experienced workers cannot guarantee the best quality of each welding.

[0005] Finally, there are safety hazards in spot welding with a handheld welding torch. Since high temperatures and sparks are generated during welding, burns can easily occur if the operation is improper or the equipment fails. This not only poses a threat to the health of workers, but also may bring the risk of production safety accidents to enterprises.

[0006] In order to solve these problems, our R&D department can consider introducing automated and intelligent welding equipment. For example, we can develop automated welding robots to automate and standardize the welding process through preset programs and precise control. This can not only improve welding efficiency and quality, but also reduce the labor intensity and safety risks of workers. To this end, a capacitor spot welding processing device is proposed.

[0029] A support column 12 is fixedly connected to the middle part of both sides of the upper surface of the operating table 11, and a support arm 13 is welded to the top of the two support columns 12. A mounting ring 14 is welded to the adjacent end of the two support arms 13, and a cylinder 15 is fixedly connected to the inner wall of the mounting ring 14.

[0031] In one embodiment, specifically: a U-shaped baffle 27 is fixedly connected to the outer side of the two support columns 12 at the rear of the upper surface of the operating table 11, and a transformer 28 and a capacitor group 29 are fixedly connected to one side of the inner wall of the U-shaped baffle 27. The output end of the transformer 28 is electrically connected to the input end of the capacitor group 29. The input AC voltage is increased to the required welding voltage through the transformer 28 and transmitted to the capacitor group 29, so that the capacitor group 29 starts to charge and store electrical energy after receiving the voltage.

[0032] In one embodiment, specifically: a mounting groove 30 is opened on one side of the front portion of the upper surface of the operating table 11, and a controller 31 is fixedly connected to the inner wall of the mounting groove 30. The cylinder 15, the electrode rod 17, the electrode plate 22, the transformer 28 and the capacitor group 29 are all connected to the controller 31. The welding parameters, including the welding current, the welding time, etc., are set by the controller 31. These parameters will determine the electrical energy stored in the capacitor and the speed of releasing the electrical energy during the welding process, thereby affecting the welding effect.

[0033] In one embodiment, specifically: a display screen 37 is disposed on the upper portion of the upper surface of the controller 31, and a control panel 32 is disposed on the lower portion of the upper surface of the controller 31, so that welding parameters can be conveniently set through the display screen 37 and the control panel 32 on the controller 31.

[0034] In one embodiment, specifically: a storage plate 33 is fixedly connected to the other side of the inner wall of the U-shaped baffle 27, and the storage plate 33 is used to facilitate the placement of tools and materials.

[0035] In one embodiment, specifically: a reinforcement ring 34 is welded to the middle part of the outer wall of the cylinder 15, the lower surface of the reinforcement ring 34 is fixedly connected to the upper surface of the mounting ring 14 by a plurality of screws 35, and the reinforcement ring 34 on the cylinder 15 is fixedly connected to the mounting ring 14 by a plurality of screws 35, thereby increasing the firmness of the cylinder 15.

[0036] In one embodiment, specifically: a support frame 36 is fixedly connected to the outer side of the lower surface of the operating table 11, and the support frame 36 supports the entire device, thereby increasing the stability of the entire device.

[0037] When the utility model is working: first, the workpiece to be welded is placed on the electrode plate 22 to ensure good contact between the workpiece and the electrode plate 22. Then, the welding parameters are set through the controller 31, including welding current, welding time, etc. These parameters will determine the electric energy stored in the capacitor during welding and the speed of releasing the electric energy, thereby affecting the welding effect. Next, the device is started, and the transformer 28 starts to work, raising the input AC voltage to the required welding voltage, and then transmitting it to the capacitor group 29. After receiving the voltage, the capacitor group 29 starts to charge and store electric energy. When the capacitor group 29 stores enough electric energy, the controller 31 issues a command to start the cylinder 15. The output end of the cylinder 15 pushes the threaded cylinder 16 to move downward. Due to the electrode rod 1 7 is threadedly connected to the threaded barrel 16, so the electrode rod 17 will also move downward with the threaded barrel 16. In the process of the electrode rod 17 moving downward, the conical spot welding head 18 gradually approaches the surface of the workpiece. When the conical spot welding head 18 contacts the surface of the workpiece, the capacitor group 29 starts to discharge and releases the stored electrical energy. The high current density welding current instantly heats and melts the material on the surface of the workpiece through the conical spot welding head 18 to achieve welding. After the welding is completed, the cylinder 15 drives the threaded barrel 16 and the electrode rod 17 to move upward, and the conical spot welding head 18 leaves the surface of the workpiece. At the same time, the heat generated by the electrode plate 22 during the welding process is transferred to the heat sink 23, and the heat is quickly dissipated through the heat sink 25 and the heat sink fan 26 on the heat sink 23 to prevent the electrode plate 22 from overheating.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
