[0042] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application after combining the specific content of the technical solution.
[0043] Reference Figures 1 to 6 The seam welding electrode mechanism of the first aspect of the present application is applied to a seam welding machine, and the seam welding electrode mechanism includes an electrode holder 100, an electrode shaft 200, an electrode wheel 210, a driving component 300 and a conductive component 400.
[0044] The electrode shaft 200 is extended along the length direction of the electrode seat 100 and is arranged on the electrode seat 100; the electrode wheel 210 is arranged at one end of the electrode shaft 200; the driving component 300 is connected to the electrode shaft 200 and is used to drive the electrode wheel 210 to rotate; and the conductive components 400 are respectively arranged on both sides of the width direction of the electrode seat 100 and are used to transfer current to the electrode shaft 200.
[0045] In some embodiments, specific reference is made to Figures 7 to 9, which are different types of products 500 to be processed, wherein the seam welding edge of the product 500 to be processed is narrow, and one surface of the product 500 to be processed not only has a convex hull 520, but also is a surface of an inner fillet 510, and the size of the inner fillet 510 is also relatively small.
[0046] It is understandable that specific reference Figure 5 and Figure 6 The diameter of the electrode wheel 210 is small and the upper and lower wheels are installed at an angle, so as not to interfere with the inner circle and convex bulge 520 of the product. The conductive components 400 are respectively arranged on both sides of the width direction of the electrode holder 100, and the double-sided conduction makes the conduction more uniform and improves the welding stability. Based on the optimization of the layout of the conductive component 400, while improving the conductive mode of the electrode holder 100, the structure is made more compact, so that the electrode wheel 210 is smaller in size, which can meet the seam welding requirements of products with small electrode installation space and high current, and meet the seam welding requirements of products with narrow welding edge width. Furthermore, based on the conductive component 400 being arranged on the side, the up and down adjustment range of each electrode wheel 210 is wider, and the upper and lower electrode wheels 210 can be installed non-parallel, thereby meeting the welding requirements of most workpieces with inner fillet 510.
[0047] In some embodiments, the electrode wheel 210 is fixed on the electrode shaft 200 and rotates synchronously therewith, the conductive component 400 is arranged on the side of the electrode holder 100, and the current of the welding power supply passes through the conductive materials, the electrode shaft 200 and the electrode wheel 210 on both sides, thereby utilizing the upper and lower seam welding electrode mechanisms for welding.
[0048] Reference Figures 1 to 6 The seam welding electrode mechanism of the first aspect of the present application distributes the conductive components 400 on both sides, which can reduce the height dimension compared with the traditional upper and lower distribution method, making the conduction more uniform, and the diameter of the electrode wheel 210 can also be reduced, thereby meeting the welding of narrow edges in a small space; at the same time, based on the conductive components 400 being arranged on both sides in the width direction, the installation and adjustment of the electrode wheels 210 spaced apart from each other are more convenient, meeting the welding of products with convex bumps 520 and inner fillets 510, and ensuring stable welding quality.
[0049] In some embodiments of the present application, the conductive assembly 400 includes a conductive strip 411, a conductive row 410 and an electrode tile 420, the conductive row 410 and the conductive strip 411 are respectively arranged on both sides of the width direction of the electrode holder 100, the conductive row 410 is electrically connected to the conductive strip 411, the conductive strip 411 is electrically connected to the electrode tile 420, and the electrode tile 420 is electrically connected to the electrode shaft 200. It can be understood that the upper and lower seam welding electrode mechanisms are the same, and the current of the welding power source passes through the conductive row 410 on both sides → the electrode holder 100 → the conductive strip 411 → the electrode tile 420 → the electrode shaft 200 → the electrode wheel 210, and the upper and lower electrode wheels 210 contact the upper and lower surfaces of the welding workpiece respectively to complete the welding.
[0050] In some embodiments, the conductive bar 410 is a copper bar, the conductive tape 411 is a conductive copper tape, and the electrode tile 420 is a silver tile. In other embodiments, the conductive tape 411, the conductive bar 410 and the electrode tile 420 may be made of other conductive materials, which will not be further described here.
[0051] In some embodiments of the present application, the conductive assembly 400 further includes an elastic member 430 and a pressing block 440. The pressing block 440 is fixed on the electrode holder 100 and is used to press the electrode tile 420. The elastic member 430 acts on the electrode tile 420 so that the electrode tile 420 is closely arranged with the electrode shaft 200. It can be understood that the pressing block 440 and the elastic member 430 are used to ensure the stability of the electrical connection. Therefore, after the electrode tile 420 is arranged against the electrode shaft 200, the pressing block 440 is fixed to the electrode holder 100 to press the electrode tile 420. The elastic members 430 on both sides are pressed so that the electrode tiles 420 and the electrode shaft 200 on the left and right sides can be closely contacted and matched, so that the conduction is completed and the electrode shaft 200 can rotate between the silver tiles on both sides.
[0052] In some embodiments, four groups of conductive strips 411 on a single side are installed alternately with the electrode tiles 420, so that the displacement amplitude of the electrode tiles 420 is smaller and the conductivity is more stable.
[0053] In some embodiments, specific reference is made to Figure 3 and Figure 4 The elastic member 430 is a spring, the conductive strip 411, the conductive row 410, the electrode tile 420, the elastic member 430 and the pressing block 440 are symmetrically distributed on both sides of the electrode holder 100. The electrode holder 100 transmits the current to the electrode shaft 200 through the conductive copper strips on both sides and the silver tiles on both sides, making the conduction more uniform.
[0054] In some embodiments of the present application, a bearing 110 is provided in the electrode holder 100, and the electrode shaft 200 is passed through the bearing 110. It is understandable that by providing the bearing 110 to support the electrode shaft 200, the friction coefficient of the electrode shaft 200 during movement can be reduced and its rotation accuracy can be ensured.
[0055] In some embodiments, bearings 110 are respectively arranged at both ends of the electrode shaft 200 in the length direction. The front and rear bearings 110 are positioned so that the electrode wheel 210 is fixed on the electrode shaft 200 and can rotate around the axis, thereby forming a structure with compact structure and high transmission accuracy.
[0056] In some embodiments of the present application, the driving component 300 includes a driving motor 310, a reducer 320 and a transmission assembly 330, the driving motor 310 is connected to the reducer 320, and the transmission assembly 330 is respectively connected to the reducer 320 and the electrode shaft 200, so that the driving motor 310 is suitable for driving the electrode wheel 210 to rotate. It is understandable that the driving motor 310 outputs power, and the power is appropriately transmitted to the electrode shaft 200 and the electrode wheel 210 through the reducer 320 and the transmission assembly 330, so that it rotates and is used for welding the workpiece. By integrating the driving component 300 on the electrode holder 100, it is convenient for the entire head to be driven by the robot for seam welding.
[0057] In some embodiments, the driving motor 310 may be a servo motor, and the power may be transmitted to the electrode shaft 200 and the electrode wheel 210 through gear transmission or chain sprocket transmission. In other embodiments, the transmission may be realized through a belt transmission structure, a connecting rod transmission structure, or a crank rocker transmission structure. In other embodiments, the driving component 300 may also be driven by hydraulic pressure or pneumatic pressure as the power, and a corresponding hydraulic transmission assembly 330 or pneumatic transmission assembly 330 may be configured, so as to realize the corresponding power transmission effect, which will not be further described here.
[0058] In some embodiments of the present application, a mounting frame 120 is provided on the electrode holder 100, and the mounting frame 120 is used to support the drive motor 310 and the reducer 320, and the transmission assembly 330 is integrated on the electrode holder 100. It can be understood that the mounting frame 120 is installed on the conductive bars 410 on both sides, the reducer 320 is installed on the mounting frame 120, and the drive motor 310 is connected to the reducer 320 to realize the integrated setting of the drive system, making the structure more compact while facilitating the entire head to be driven by the robot and realize the seam welding operation. In some embodiments, the mounting frame 120 includes an arched mounting portion and feet arranged at both ends of the bottom of the mounting portion, which are respectively fixed to the copper bars on both sides through the feet, and are connected to the reducer 320 by the mounting portion, so as to meet the installation requirements through structural design.
[0059] In some embodiments of the present application, the transmission assembly 330 includes a driving wheel 331, a synchronous belt 332 and a driven wheel 333, the driving wheel 331 is connected to the reducer 320, the synchronous belt 332 is respectively connected to the driving wheel 331 and the driven wheel 333, and the driven wheel 333 is connected to the electrode shaft 200. It can be understood that the transmission accuracy can be ensured by using the synchronous belt 332 transmission, the servo motor transmits power to the driven synchronous belt 332 wheel through the driving synchronous belt 332 wheel and the synchronous belt 332, and the driven synchronous belt 332 wheel is connected to the electrode shaft 200, thereby improving the entire driving process and ensuring stable welding quality.
[0060] Reference Figures 1 to 6The seam welding machine of the second embodiment of the present application includes the seam welding electrode mechanism of the first embodiment of the present application, which welds the workpiece through the upper and lower spaced electrode wheels 210, can meet various welding requirements while ensuring welding quality.
[0061] In some embodiments of the present application, the seam welding electrode mechanism has two electrodes 210 that are arranged in a spaced relationship, and the axes of the two electrode wheels 210 are in a non-parallel state. It is understandable that, based on the copper bar being fixed on both sides of the electrode holder 100, the size of the electrode holder 100 can be adjusted accordingly while the overall size in the up-down direction is reduced, so that the diameter of the electrode wheel 210 becomes smaller, thereby meeting the welding of narrow edges in a small space, and further achieving the non-parallel installation of the upper and lower electrode wheels 210 to meet the welding of products with convex bumps 520.
[0062] In some embodiments, the upper motor wheel and the lower electrode wheel 210 can be arranged horizontally in a conventional manner. In other embodiments, the upper electrode wheel 210 can be arranged horizontally, and the lower electrode wheel 210 can be arranged upwardly inclined. In other embodiments, the lower electrode wheel 210 can be arranged horizontally, and the upper electrode wheel 210 can be arranged downwardly inclined. In other embodiments, refer to Figure 6 The upper electrode wheel 210 and the lower electrode wheel 210 can be arranged close to each other in an inclined manner and can be adjusted accordingly according to actual conditions to meet welding requirements.
