Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0040] The present invention first provides a cantilever welding mechanism 100, such as Figure 1 As shown, it includes a column 1, a beam 2 and a mounting frame 3, wherein the column 1 is arranged in the vertical direction; one end of the beam 2 is rotatably connected to the top of the column 1, and the other end of the beam 2 is suspended; the mounting frame 3 is slidably installed on the beam 2, and the sliding direction is along the long axis direction of the beam 2; a transverse rib blanking mechanism 4 is provided on one side of the mounting frame 3 for blanking the transverse ribs 300, a welding upper electrode mechanism 5 is provided on the other side of the mounting frame 3, and a welding lower electrode mechanism 6 is provided at the bottom of the mounting frame 3.

[0041] In the cantilever welding mechanism 100 provided by the present invention, the transverse rib blanking mechanism 4, the welding upper electrode mechanism 5 and the welding lower electrode mechanism 6 are all arranged on the mounting frame 3, the mounting frame 3 is slidably connected to the crossbeam 2, and the crossbeam 2 is rotatably connected to the column 1, thereby realizing the synchronous rotation and movement of the transverse rib blanking mechanism 4, the welding upper electrode mechanism 5 and the welding lower electrode mechanism 6, and thus, each time the transverse rib 300 is welded, the blanking and welding of the transverse rib 300 can be realized synchronously, without moving the flat mesh mold 200. According to the curvature and length of the bending arc of the flat mold, the crossbeam 2 is rotated or the mounting frame 3 is moved for adaptation, thereby solving the problem of large welding operation space caused by the inability to move the transverse rib 300 welding mechanism in the prior art, which is beneficial to improving the flat mesh welding forming efficiency.

[0042] In some embodiments, the beam 2 and the column 1 are perpendicular to each other. When the beam 2 rotates around the column 1, the beam 2 at any position within the length of the flat mesh mold 200 can be welded. When the mounting frame 3 moves along the beam 2, the axial rotation of the beam 2 and the radial movement of the mounting frame 3 cooperate to achieve the blanking and welding of the transverse ribs 300 on the curved flat mesh mold 200, and the welding and forming efficiency of the flat mesh is greatly improved.

[0043] In some embodiments, the cantilever welding mechanism 100 further includes a rotating drive member 7, which is disposed on the column 1. A rotating shaft 11 is disposed at the top of the column 1, and the beam 2 is fixedly connected to the rotating shaft 11. The rotating drive member 7 is configured to drive the rotating shaft 11 to rotate.

[0044] like Figure 1 As shown, the provision of a rotating drive member 7 facilitates automatic control of the rotation of the crossbeam 2 and facilitates control of the rotation angle of the crossbeam 2. The control terminal can also record the angle of each rotation, making it suitable for batch welding of cross ribs 300 for multiple flat mesh molds 200, resulting in good consistency of the flat mesh and high production efficiency. The provision of a rotating shaft 11 further facilitates installation of the crossbeam 2, which is directly driven by the rotating shaft 11, resulting in good synchronization.

[0045] In some embodiments, a driving gear 71 is provided at the output end of the rotating driving member 7 , a transmission gear 12 is fixedly connected to the rotating shaft 11 , and the driving gear 71 is meshed and transmission-connected with the transmission gear 12 .

[0046] like Figure 1 As shown, the rotary drive member 7 can be a stepper motor. The main body of the rotary drive member 7 is fixed to the column 1. The output end of the rotary drive member 7 is fixedly connected to the drive gear 71. The diameter of the drive gear 71 is smaller than that of the transmission gear 12. This allows the crossbeam 2 to rotate over a wide range of angles, facilitating adaptation to a variety of flat mesh molds 200 and greatly improving versatility. The rotating shaft 11 and the transmission gear 12 are coaxially arranged to achieve circular motion of the crossbeam 2. The rotation radius is fixed, making it easy to control.

[0047] In some embodiments, the cantilever welding mechanism 100 further includes a movable driving member 8 , which is disposed on the beam 2 , and an output end of the movable driving member 8 is connected to the mounting frame 3 .

[0048] Among them, the mobile driving component 8 can adopt a linear driving mechanism such as a cylinder or an oil cylinder. The mobile driving component 8 is used to drive and control the radial movement of the mounting frame 3. During blanking and welding, the mobile driving component 8 drives the mounting frame 3 to extend in the direction away from the column 1. Each time the welding of a transverse rib 300 is completed, the mobile driving component 8 drives the mounting frame 3 to retract to the initial position in the direction close to the column 1.

[0049] In some embodiments, a mounting plate 24 is provided below the crossbeam 2 , and the moving driving member 8 is fixedly connected between the mounting plate 24 and the mounting frame 3 .

[0050] like Figure 1 As shown, the mounting plate 24 is arranged in the vertical direction, the top end of the mounting plate 24 is fixedly connected to the lower surface of the beam 2, and the output end of the mobile driving member 8 is arranged along the long axis direction of the beam 2. By setting the mounting plate 24, it is convenient to make the driving direction of the mobile driving member 8 parallel to the long axis direction of the beam 2, and utilize installation positioning and drive control.

[0051] In some embodiments, a slider 25 is provided on the crossbeam 2 , a slide rail 31 is provided on the top of the mounting frame 3 , and the slider 25 is installed in a sliding cooperation with the slide rail 31 .

[0052] like Figure 1 As shown, the lower surface of the suspended end of the crossbeam 2, away from the column 1, is provided with multiple sets of sliders 25. Slide rails 31 are disposed at the top of the mounting frame 3. When retracted, the slide rails 31 pass through the space above the movable drive member 8 and abut against the mounting plate 24 to define the initial position. The placement of the slide rails 31 on the mounting frame 3 allows the mounting frame 3 to have a greater travel range. When in the retracted position, the mounting frame 3 can be completely retracted beneath the crossbeam 2, preventing structural interference during the rotation of the crossbeam 2.

[0053] In some embodiments, the mounting frame 3 includes an L-shaped vertical beam 32 and a transverse beam 33 , the welding lower electrode mechanism 6 is arranged on the transverse beam 33 of the mounting frame 3 , and the transverse rib blanking mechanism 4 and the welding upper electrode mechanism 5 are relatively arranged on both sides of the vertical beam 32 .

[0054] For example Figure 1The top of the vertical beam 32 is connected to the output end of the mobile driving member 8 through a fixing mechanism, the slide rail 31 is set on the fixing mechanism, one end of the transverse beam 33 is fixedly connected to the bottom end of the vertical beam 32, the transverse beam 33 is set on the side of the vertical beam 32 away from the column 1, and a pair of welding lower electrode mechanisms 6 are installed on the transverse beam 33. The transverse rib blanking mechanism 4 in the embodiment of the present invention is a prior art product, which is used to realize the loading and blanking of the transverse ribs 300 on the flat mesh mold 200. The welding upper electrode mechanism 5 and the welding lower electrode mechanism 6 are set correspondingly and in pairs. After the transverse ribs 300 are blanked, the welding upper electrode mechanism 5 and the welding lower electrode mechanism 6 realize the simultaneous welding and fixing of the two ends of the transverse ribs 300.

[0055] In some embodiments, the crossbeam 2 includes an upper beam 21, a lower beam 22, and a longitudinal beam 23 connecting the upper and lower beams 21, 22. The longitudinal beams 23 are evenly spaced along the long axis of the crossbeam 2. Both the upper and lower beams 21, 22 are connected to the rotating shaft 11, providing strong connection strength and facilitating installation. Furthermore, the longitudinal beams 23 utilize a frame structure, which reduces weight. Both the upper and lower beams 21, 22 are constructed of plates and secured to the outer wall of the rotating shaft 11 by welding, facilitating connection.

[0056] The present invention further provides a cantilever welding method, which uses the cantilever welding mechanism 100 provided by the present invention. The cantilever welding method includes the following steps:

[0057] S1, the cantilever welding mechanism 100 and the flat mesh mold 200 are spaced apart, and the welding positions of the plurality of transverse ribs 300 on the flat mesh mold 200 are determined; Figure 2 As shown, a cantilever welding mechanism 100 is provided on the concave arc side of the flat mesh mold 200, and the crossbeam 2 can reach both ends of the flat mesh mold 200 when rotating within the fan surface.

[0058] S2, driving the crossbeam 2 to rotate around the column 1 to the welding position facing the first crossbeam 300; in this embodiment, the welding position of the first crossbeam 300 is Figure 2 The leftmost position.

[0059] S3, driving the mounting frame 3 to move toward the flat mesh mold 200 and extend it into position; here, the blanking is determined according to the transverse rib blanking mechanism 4, or it is preset before starting.

[0060] S4, the transverse rib blanking mechanism 4 on the mounting frame 3 blanks the transverse rib 300, and the upper welding electrode mechanism 5 and the lower welding electrode mechanism 6 weld the two ends of the transverse rib 300 respectively;

[0061] S5, the mounting frame 3 retracts to the initial position;

[0062] S6, driving the crossbeam 2 to rotate around the column 1 to the next welding position; preferably, the crossbeam 2 is stepped in a clockwise direction to realize the gradual blanking and welding of the transverse ribs 300.

[0063] S7, repeat steps S3-S6 until all transverse reinforcements 300 are welded.

[0064] The cantilever welding method provided by the present invention utilizes the cantilever welding mechanism 100 provided by the present invention. By controlling the overall rotation and movement of the transverse rib blanking mechanism 4, the upper welding electrode mechanism 5, and the lower welding electrode mechanism 6, this method solves the problem of large welding operating space caused by the immobility of the transverse rib 300 welding mechanism in the prior art, thereby improving the efficiency of flat mesh welding. The crossbeam 2 rotates clockwise or counterclockwise to a set angle corresponding to the blanking position of the transverse rib 300, and the mounting frame 3 moves and retracts to achieve blanking and welding. The welding process is simple and easy to control, fully utilizing the vertical space, thereby reducing the welding equipment's footprint.
