Description

Technical Field

[0001] The utility model relates to the technical field of welding, and more specifically, to an inert gas blowing device and a welding system. Background Art

[0002] When welding workpieces, in order to prevent oxidation of the welding area, argon or other inert gases must be blown to isolate oxygen during the welding process. Currently, the vast majority of manufacturers use a method of directly blowing the welding area with a universal air blowing head for protection. Due to the large volume of the universal air blowing head, it is impossible to blow air at multiple points simultaneously. Therefore, after welding one area, when welding the next area, it is necessary to readjust the blowing position of the universal air blowing head again, resulting in inconvenient use and affecting the welding efficiency. In addition, after manually adjusting the blowing position of the universal air blowing head, the blowing angle and blowing distance may not meet the welding requirements, leading to the need to repeatedly adjust the blowing position of the universal air blowing head, thereby increasing the welding instability and defect rate.

[0033] Please refer to Figures 1-3 , this embodiment provides an inert gas blowing device 100, and the inert gas blowing device 100 includes a main body 110, a plurality of blowing heads 120, and a plurality of plugs 130;

[0034] The main body 110 is configured with an air storage cavity or an air flow channel 111, and a plurality of air outlets 112 communicating with the air storage cavity or the air flow channel 111;

[0035] Among them, each air outlet 112 corresponds to a blowing head 120 and a plug 130, and the blowing head 120 and the plug 130 are alternatively communicated with the corresponding air outlet 112.

[0036] It should be noted that during the welding process, the main reason for blowing argon gas is that argon, as an inert gas, has very inactive chemical properties and can neither burn nor support combustion. When welding special metals such as aluminum, magnesium, copper and their alloys, and stainless steel, using argon as a shielding gas can prevent the welded parts from being oxidized or nitrided by air, thus ensuring high-quality welding. Argon forms an inert gas protective layer during the welding process, isolating the intrusion of air, protecting the arc and molten pool, avoiding the burning loss of alloying elements and other welding defects, and making the metallurgical reaction simple and easy to control.

[0037] Although argon is the most commonly used inert gas, in some cases, other gases can also be used as alternatives. These gases that can replace argon are collectively referred to as inert gases, including helium (He), neon (Ne), krypton (Kr), xenon (Xe), radon (Rn), etc. However, each gas has its specific physical and chemical properties, which may have different effects on the welding process and results.

[0038] Therefore, for the above reasons, during the operation of the inert gas blowing device 100, the type of inert gas blown can be selected according to the usage requirements. In this embodiment, taking the welding of the mobile phone frame as an example, based on this, the inert gas blown is taken as argon for illustration.

[0039] Please refer to Figures 1-4 , the working principle of the inert gas blowing device 100 is:

[0040] The inert gas blowing device 100 includes a main body 110, a plurality of blowing heads 120 and a plurality of plugs 130; the main body 110 is configured with an air storage cavity or an air flow channel 111, and a plurality of air outlets 112 communicating with the air storage cavity or the air flow channel 111;

[0041] Based on this, since the main body 110 is provided with a plurality of air outlets 112, during use, one or more of them can be selected according to the usage requirements to blow gas to the welding position. The gas in this embodiment refers to inert gas, and thus, in this way, the formation of an inert gas protective layer can be improved, the intrusion of air can be isolated, and the welding quality can be improved;

[0042] On this basis, when configuring the main body 110, according to the usage requirements, especially when carrying out batch welding work, the shape structure of the main body 110 can be correspondingly set according to the shape of the material to be welded, so that the main body 110 has a shape adapted to the welding material 10. Furthermore, a plurality of air outlets 112 located outside the main body 110 are all corresponding to the welding positions on the welding material 10, so that each air outlet 112 can blow gas to the corresponding welding position on the corresponding welding material 10. That is, on the basis of the adaptation of the shape of the main body 110 to the welding material 10, the adaptability between the air outlets 112 on the main body 110 and the welding positions on the welding material 10 can be improved. Furthermore, in this way, the welding quality can be improved, the operation in the welding process can be simplified, the adjustment of the position of the main body 110 can be reduced, so that during the welding process, only the air outlets 112 capable of blowing gas need to be adjusted;

[0043] On the basis of the above structure, since each air outlet 112 corresponds to the welding position on the welding material 10, and as the welding progresses in sequence, it is necessary to adjust the air outlet state of each air outlet 112 according to the welding process flow. That is, to facilitate the adjustment of the air outlet state of each air outlet 112 according to the welding requirements during the welding process, therefore, each air outlet 112 corresponds to a blowing head 120 and a plug 130, and either the blowing head 120 or the plug 130 is connected to the corresponding air outlet 112; in this way, during the welding process, by installing a plug 130 or a blowing head 120 at each air outlet 112, the air outlet state of each air outlet 112 can be quickly adjusted;

[0044] In summary, the inert gas blowing device 100 is applied to the welding system 200. During its use, since the positions of the air outlets 112 are set to be adaptable to the welding material 10, it is possible to sequentially connect some of the air outlets 112 to the blowing heads 120 to blow gas according to the welding process flow, and the idle air outlets 112 are blocked by the plugs 130, thereby reducing the waste of inert gas. Thus, it is possible to conveniently adjust the appropriate gas blowing position, improve the accuracy of gas blowing, reduce the waste of gas, thereby improving the welding efficiency, improving the welding quality, and reducing the welding cost.

[0045] It should be noted that during the welding process, through the above settings of the plurality of air outlets 112, on the basis of achieving the above-mentioned purposes and technical effects, the gas blowing range of the inert gas blowing device 100 can also be expanded through the settings of the plurality of air outlets 112, so as to adapt to the welding processing requirements of a variety of different materials, thereby reducing its usage cost.

[0046] It should also be noted that the blowing direction of the gas can be limited by setting the structure of the blowing head 120. Similarly, the blowing direction can also be adjusted by adjusting the installation state and structural dimensions of the blowing head, so as to expand the applicable range of the inert gas blowing device 100.

[0047] Furthermore, please refer to Figures 1-4 , in this embodiment, as can be seen from the above, this embodiment is for welding the mobile phone frame. Based on this, the main body 110 can be set as a cuboid. Based on this, the way adopted in this embodiment is to distribute a plurality of air outlets 112 at intervals on the outer peripheral surface of the main body 110. At this time, the welding material 10 can be located below, above or on its outer periphery, that is, through such a setting method of the air outlets 112, the demand for blowing gas to the materials above, below or on its outer periphery can be met.

[0048] As can be seen from the above, in this embodiment, the main body 110 is configured with an air capacitance chamber or an air flow channel 111, and the air capacitance chamber or the air flow channel 111 is used to communicate with an external air source to receive the gas transported by the external air source and transport the gas to each air outlet 112; on this basis, for the convenience of communicating with the external air source, at least one air inlet interface 113 communicating with the air capacitance chamber or the air flow channel 111 is arranged on the upper end surface of the main body 110. Such a setting method makes the air inlet pipeline 140 located above it, so that the installation of the air inlet pipeline 140 can be facilitated. In addition, two air inlet interfaces 113 are arranged on the upper end surface of the main body 110. The two air inlet interfaces 113 are arranged at intervals, and one of the two air inlet interfaces 113 is selectively communicated with the external air source. Such a setting method can optimize its air inlet installation method, that is, the air inlet interface 113 can be arranged at different positions on its upper end surface, and then one of the positions can be selected to communicate with the external air source according to the demand, so as to avoid the interference between the air inlet pipeline 140 and other structures during the process of communicating with the external air source. Moreover, such a setting method can, in the case of a failure of one of the air inlet structures, communicate with the external air source through the other air inlet structure, so as to improve its anti-risk ability and reduce its maintenance cost.

[0049] Further, in this embodiment, when configuring the main body 110, in order to enable each of the plurality of air outlets 112 to discharge the gas delivered by the external air source, therefore, a main flow channel 114 and a plurality of sub-flow channels 115 are configured in the main body 110. The main flow channel 114 extends along the width or length direction of the main body 110. The plurality of sub-flow channels 115 are all communicated with the main flow channel 114, and each sub-flow channel 115 is correspondingly communicated with at least one air outlet 112. Among them, the air inlet interface 113 is communicated with the main flow channel 114 or one of the sub-flow channels 115. Thus, in this way, the external air source can be correspondingly delivered to each air outlet 112 through the built-in main flow channel 114 and the plurality of sub-flow channels 115.

[0050] In addition, on this basis, it should be noted that on the basis of configuring the above-mentioned main flow channel 114 and the plurality of sub-flow channels 115, an air capacitance chamber can be set at the same time. The purpose is to enable the main body 110 to have a certain gas storage function, so as to ensure that each air outlet 112 can discharge gas quickly. At the same time, in this way, it is also convenient to improve the consistency of the air outlet pressure and flow rate of each air outlet 112 when the plurality of air outlets 112 discharge gas simultaneously, so as to improve the welding quality.

[0051] Further, please refer to Figures 1-4 , as can be seen from the above, this embodiment takes the main body 110 as a cuboid as an example for illustration. That is, the outer periphery of the main body 110 is provided with four continuous side surfaces 116. On this basis, at least two air outlets 112 can be distributed on each side surface 116. In other embodiments of the present invention, on the basis of the foregoing structure, the number of air outlets 112 on each side surface 116 of the main body 110 and the distance between adjacent air outlets 112 can be adjusted according to the usage requirements. In addition, in order to adapt to the welding of the mobile phone frame, at least one transition surface 117 can be configured on the outer periphery of the main body 110. The transition surface 117 is located at the intersection of two adjacent side surfaces 116, and at least one air outlet 112 is configured on the transition surface 117 to meet the welding requirements.

[0052] Further, on the basis of the above structure, this embodiment adopts the method of making the main body 110 have a corresponding contour shape with the welding material 10. Thus, in order to facilitate quick positioning with the welding material 10 during the installation process to improve the welding efficiency, a through positioning connection hole 118 is configured in the middle of the main body 110. In this way, the positioning and installation steps of the inert gas blowing device 100 can be quickly completed to improve the operation efficiency;

[0053] As can be seen from the foregoing, in order to improve the applicable range of the inert gas blowing device 100, the positioning connection hole 118 is a strip-shaped hole, so that the inert gas blowing device 100 can adapt to the welding requirements of more welding materials 10.

[0054] Based on the above, please refer to Figures 1-4 , this embodiment further provides a welding system 200. The welding system 200 includes a workbench 210 and the above-mentioned inert gas blowing device 100; the workbench 210 is configured with a welding station for placing the workpiece to be welded, the inert gas blowing device 100 is connected to the workbench 210, and the inert gas blowing device 100 is used to blow inert gas toward each welding point on the workpiece to be welded located at the welding station.

[0055] In summary, by adopting the above-mentioned inert gas blowing device 100, the welding system 200 can, during the welding process, according to the welding process flow, sequentially connect some of the air outlets 112 to the blowing heads 120 for gas blowing, and block the idle air outlets 112 with the plugs 130, so as to reduce the waste of inert gas. Thus, it can not only conveniently adjust the gas blowing position, improve the accuracy of gas blowing, but also reduce the waste of gas, thereby improving the welding efficiency, improving the welding quality, and reducing the welding cost.

[0056] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
