[0053] like Figures 1-8 As shown, this utility model embodiment provides an automatic forming and welding equipment for a grid arch frame, used for the automatic welding and forming of a grid arch frame 100. The grid arch frame 100 includes four main ribs 101 and multiple butterfly ribs 102. Angle steel 103 is provided at both ends of the four main ribs 101 for fixation. The automatic forming and welding equipment for the grid arch frame provided in this utility model embodiment can realize automatic feeding, automatic bending and positioning, and automatic welding of the main ribs 101 and butterfly ribs 102, thereby improving the automatic forming and welding efficiency of the grid arch frame 100. Specifically, the automatic forming and welding equipment for grating arches includes a frame 1, a robotic arm 2, a butterfly rib feeding device 3, a main rib feeding device 4, and an arch forming device. A rotating frame 11 is rotatably mounted on the frame 1, with its rotation axis set along the X-direction. A crossbeam 12 is located above the rotating frame 11 on the frame 1, extending along the X-direction. The robotic arm 2 is mounted on the crossbeam 12, and a welding assembly 21 is located at the free end of the robotic arm 2. The welding assembly 21 is used to weld the main ribs 101 and butterfly ribs 102 into shape. The butterfly rib feeding device 3 is located on the rotating frame 11. Below, multiple butterfly ribs 102 are spaced apart along the X-direction on the butterfly rib feeding device 3, and can drive multiple butterfly ribs 102 to move up and down simultaneously for feeding. The butterfly ribs 102 are movably mounted on the butterfly rib feeding device 3. The main rib feeding device 4 is located at one end of the rotating frame 11 and is used to provide multiple main ribs 101. The arch frame forming device includes multiple pairs of adjusting components 5, which are spaced apart along the X-direction on the rotating frame 11. The multiple pairs of adjusting components 5 are used to bend the four main ribs 101 into a specified shape, so as to realize the automatic extrusion forming of the main ribs 101 and the butterfly ribs 102.

[0054] The automatic forming and welding equipment for grid arch frames provided by this utility model uses a rotating frame 11 mounted on the frame 1, and the arch frame forming device is set on the rotating frame 11. The rotation of the rotating frame 11 enables the feeding of multiple main ribs 101 and the welding of both sides of the grid arch frame 100. This simplifies the main rib feeding device 4 and reduces the number of welding components 21, saving costs and improving feeding and welding efficiency. By setting a butterfly rib feeding device 3 to drive multiple butterfly ribs 102 to move up and down simultaneously for feeding, manpower is saved and automatic feeding of butterfly ribs 102 is realized. The butterfly ribs 102 can follow the movement of the main ribs 101, improving the initial automatic positioning efficiency of butterfly ribs 102 and main ribs 101. The feeding efficiency is high and the positioning efficiency is high, thereby improving the forming efficiency of the grid arch frame 100. Among them, the main rib feeding device 4 has a degree of freedom of movement along the Y direction. The main rib feeding device 4 realizes the separate feeding of the two main ribs 101 above by moving. After the rotating frame 11 rotates 180°, the main rib feeding device 4 realizes the feeding of the other two main ribs 101 again by moving along the Y direction.

[0055] In some embodiments, two pairs of adjustment components 5 are arranged opposite each other along the Y direction and can move synchronously along the Y direction. Multiple pairs of adjustment components 5 move according to the shape of the grid arch 100 to drive the four main ribs 101 to bend at different positions.

[0056] like Figures 4-7 As shown, where, Figure 4 and Figure 5 These are schematic diagrams of automatic extrusion forming of two types of grid arch frames 100. Two pairs of adjustment components 5 simultaneously clamp the same segment positions of four main ribs 101. The two pairs of adjustment components 5 drive the four main ribs 101 to move simultaneously in the positive or negative Y direction. Multiple pairs of adjustment components 5 have a moving distance set according to the curvature of the grid arch frame 100 along the X direction, thereby realizing the curvature forming of the main ribs 101. Since the butterfly ribs 102 are movably installed on the butterfly rib feeding device 3, when the main ribs 101 move and deform, the butterfly ribs 102 can follow the main ribs 101 to maintain the positioning relationship between the butterfly ribs 102 and the main ribs 101. The bending arc is simultaneously achieved to achieve final positioning, which facilitates the welding component 21 to directly weld the main ribs 101 and butterfly ribs 102. It is understood that the welding component 21 is located at the free end of the robotic arm 2. The robotic arm 2 is a mechanical structure with multiple degrees of freedom. It can drive the welding component 21 to weld multiple butterfly ribs 102 onto the main rib 101 in sequence along the X direction. After one side is welded, the butterfly ribs 102 and the main rib 101 are fixed. At this time, the butterfly rib feeding device 3 can be lowered to the clearance position so that the rotating frame 11 can rotate and flip. The welding component 21 continues to weld the other side of the butterfly ribs 102 and the main rib 101 to form a grid arch frame 100.

[0057] In some embodiments, the adjustment assembly 5 includes a first drive member 51, a cylinder seat 52, and a gripper cylinder 53. The first drive member 51 is fixed on the rotating frame 11. The output end of the first drive member 51 is provided with a lead screw 511, which extends along the Y direction. The first drive member 51 is used to drive the lead screw 511 to move along the Y direction. The end of the lead screw 511 is provided with a base plate 512, and two cylinder seats 52 are spaced apart on the base plate 512. Two gripper cylinders 53 are provided, and the two gripper cylinders 53 are respectively fixed on the two cylinder seats 52. Each gripper cylinder 53 can clamp and fix one main rib 101.

[0058] like Figure 8 In this embodiment, the first driving component 51 is a linear driving component, such as a cylinder, or a lead screw 511 lifting mechanism. The moving direction of the lead screw 511 is along the Y direction. The lead screws 511 of the two paired adjusting components 5 are coaxial and collinear. The opposite ends of the two lead screws 511 are fixedly provided with base plates 512. The base plates 512 are vertical (Z direction) and perpendicular to the lead screws 511. Two cylinder seats 52 are spaced apart along the Z direction on the base plates 512 and are respectively provided on the upper and lower sides of the lead screws 511. A gripper cylinder 53 is fixedly installed on each cylinder seat 52. When the main rib 101 is fed, the two paired adjusting components 5 are first moved away from each other and located in their respective initial positions, that is, multiple adjusting components 5 are arranged collinearly on the same side along the X direction. In order to facilitate the feeding of the main rib feeding device 4, such as Figure 4 The rotating frame 11 is equipped with multiple guide structures 13, and each guide structure 13 is correspondingly arranged with a multiple gripper cylinder 53. Specifically, for example... Figure 8 The gripper cylinder 53 includes gripping fingers 531, which are semi-circular sleeves. The main rib 101 can be gripped in two semi-circular sleeves. Multiple guide structures 13 can guide the main rib 101 into the multiple semi-circular sleeves respectively, improving the feeding efficiency of the main rib 101. Of course, in some embodiments, the guide structures 13 can also be directly fixedly installed on the gripping fingers 531. The two conical shell structure guide structures 13 form a funnel-shaped guide part after the gripping fingers 531 are engaged. After the main ribs 101 in the pair of adjustment components 5 are fed by the main rib feeding device 4 along the Y direction, the rotating frame 11 rotates, and the main rib feeding device 4 feeds the other two main ribs 101. It can be understood that the guide structures 13 are provided in two rows, corresponding to the moving feeding direction of the main rib feeding device 4 respectively.

[0059] In some embodiments, the rotating frame 11 has support rollers 111 at both ends, the support rollers 111 are rotatably mounted on the frame 1, and at least one support roller 111 is connected to a second drive member 112, the second drive member 112 being configured to drive the support rollers 111 to rotate so as to drive the rotating frame 11 to rotate.

[0060] like Figure 4 The second driving component 112 is used to drive the rotation of the rotating frame 11. In a preferred embodiment, a limiting structure can be provided on the frame 1 to limit the rotation position of the rotating frame 11, avoiding excessive rotation or reverse rotation and ensuring work consistency. The support rollers 111 are fixed at both ends of the rotating frame 11. The second driving component 112 can be driven and controlled by a servo motor and a reducer 113. Both the reducer 113 and the servo motor are fixed on the frame 1. The output end of the reducer 113 is provided with a first sprocket 114, and the support rollers 111 are provided with a second sprocket 115. A chain 116 is installed between the first sprocket 114 and the second sprocket 115 for transmission, so as to drive the rotation of the support rollers 111 and the rotating frame 11. The diameter of the first sprocket 114 is smaller than the diameter of the second sprocket 115.

[0061] In some embodiments, the free end of the robotic arm 2 is further provided with a first gripping component 22, which is used to grip the angle steel 103 and feed it to the end of the main rib 101.

[0062] like Figure 2 As shown, the robotic arm 2 is a multi-degree-of-freedom robotic arm. When the length of the grid arch 100 along the X-direction is large, the robotic arm 2 can be slidably mounted on the crossbeam 12 and automatically driven to move. In this embodiment, two robotic arms 2 are spaced apart along the X-direction on the crossbeam 12. Each robotic arm 2 has a welding component 21 and a first gripping component 22 at its free end. During welding, the two robotic arms 2 simultaneously drive the two welding components 21 to weld the same butterfly rib 102 to the main rib 101, and perform welding sequentially. After welding, the welding components 21 move away from the grid arch 100, and the first gripping component 22 grips two angle steels 103 and places them at both ends of the main rib 101. The two welding components 21 weld the two angle steels 103 to both ends of the main rib 101. The first gripping component 22 can grip the angle steels 103 by magnetic adsorption or clamping, whichever is more specific.

[0063] In some embodiments, the automatic forming and welding equipment for the grid arch further includes a cantilever crane 6, which is fixed to one side of the frame 1. The cantilever crane 6 includes a second gripping component 61 for gripping the formed grid arch 100.

[0064] like Figure 2 The cantilever crane 6 is set on one side of the frame 1 and is generally fixed to the ground. The cantilever crane 6 is equipped with a second gripping component 61, which generally includes two grippers. The relative movement of the two grippers can grip or release the grid arch frame 100, thereby lifting the welded grid arch frame 100 away from the rotating frame 11 so as to form the next grid arch frame 100.

[0065] In some embodiments, at least two rotating frames 11 are provided, and the at least two rotating frames 11 are spaced apart along the Y direction on the frame 1. Each rotating frame 11 is provided with an arch frame forming device, and a butterfly rib feeding device 3 is provided below each rotating frame 11.

[0066] In this embodiment, two rotating frames 11 are provided, such as... Figure 3 Two rotating frames 11 are spaced apart along the Y direction. Two butterfly rib feeding devices 3 feed materials to the two rotating frames 11 respectively. Two robotic arms 2 simultaneously weld and form the grid arch frame 100 on one rotating frame 11, and then turn to the other rotating frame 11 to weld and form another grid arch frame 100. At the same time, the cantilever crane 6 performs the unloading operation on the formed grid arch frame 100 on the first rotating frame 11. The main rib feeding device 4 and the butterfly rib feeding device 3 feed the main rib 101 and the butterfly rib 102 to the first rotating frame 11, so as to realize the sequential welding and forming of the two grid arch frames 100, which helps to improve efficiency.

[0067] In some embodiments, the butterfly rib feeding device 3 includes a mobile lifting trolley 31, a transition seat 33, and a positioning seat 34. The top of the mobile lifting trolley 31 is provided with a base 32. The mobile lifting trolley 31 can drive the base 32 to move below the rotating frame 11 and perform lifting and lowering movements so that the butterfly rib 102 is aligned with the main rib 101. Multiple transition seats 33 are provided, and multiple transition seats 33 are spaced apart on the base 32 along the X direction. Each transition seat 33 is slidably installed on the base 32, and the sliding direction is along the Y direction. The positioning seat 34 is rotatably disposed on the transition seat 33, and the rotation axis is disposed along the Z direction. The butterfly rib 102 is disposed on the positioning seat 34, and the butterfly rib 102 can adaptively move and rotate to be positioned according to the curvature of the main rib 101.

[0068] like Figure 9 and Figure 10The mobile lifting trolley 31 is capable of movement to facilitate the installation and loading of the butterfly ribs 102. The mobile lifting trolley 31 is equipped with an autonomous movement control mechanism. It can be moved and lifted using a scissor lift with wheels at the bottom. The base 32 is fixed to the top lifting platform of the mobile lifting trolley 31. A transition seat 33 is slidably mounted on the base 32 along the Y-axis, and a positioning seat 34 is rotatably mounted on the transition seat 33. When the butterfly ribs 102 are installed on the positioning seat 34, they can rotate and move with the moving part after being subjected to the force of the main rib 101. This allows multiple butterfly ribs 102 to be positioned relative to the main rib 101 while the main rib 101 is bending, improving positioning efficiency. The upper surface of the base 32 is provided with two parallel slide rails 321, and the lower surface of the transition plate is provided with two sets of sliders 331. Each set of two sliders 331 is slidably mounted on one slide rail 321. The two slide rails 321 are arranged along the Y direction, and the base 32 extends along the X direction. Two or more transition seats 33 can be arranged at intervals on one base 32, thereby allowing multiple butterfly ribs 102 to be installed. Preferably, the cross-section of the slide rails 321 and the sliders 331 is T-shaped.

[0069] In some embodiments, the butterfly tendon feeding device 3 further includes a first elastic element 35 and a second elastic element 36. The two ends of the first elastic element 35 are respectively connected to the base 32 and the transition seat 33, and the transition seat 33 can slide and reset under the elastic force of the first elastic element 35. The two ends of the second elastic element 36 are respectively connected to the transition seat 33 and the positioning seat 34, and the positioning seat 34 can rotate and reset under the action of the second elastic element 36.

[0070] The first elastic element 35 can reset the transition seat 33 to its initial position, facilitating the installation of the next butterfly rib 102 and ensuring consistent adjustment of the initial positions of multiple butterfly ribs 102. This prevents insufficient movement of the butterfly ribs 102 during automatic positioning, which could affect the positioning effect. The first elastic element 35 can be a spring, specifically a compression spring or a tension spring. In some embodiments, two first elastic elements 35 are spaced apart between the base 32 and the transition seat 33. When the transition seat 33 slides on the machine base, one first elastic element 35 stretches while the other compresses, ensuring successful reset of the transition seat 33. For example... Figure 10When the second elastic element 36 is a spring, its two ends are connected to the transition seat 33 and the positioning seat 34, respectively. When the positioning seat 34 rotates relative to the transition seat 33, the second elastic element 36 is stretched or compressed to generate elastic force. After the grid arch frame 100 is welded and transferred, the positioning seat 34 returns to its initial position under the elastic force of the second elastic element 36. The transition seat 33 and the positioning seat 34 are each made of plates, which are parallel to each other and spaced apart. The second elastic element 36 is located between the two plates and its two ends are fixed by connectors. In some embodiments, two second elastic elements 36 are spaced apart between the transition seat 33 and the positioning seat 34. When the positioning seat 34 rotates, one second elastic element 36 is compressed to generate elastic force, and the other second elastic element 36 is extended to generate elastic force. The elastic forces of the two second elastic elements 36 act simultaneously on the positioning seat 34 to achieve the rotational reset of the positioning seat 34, which helps to ensure the reset effect. Of course, in some embodiments, the second elastic element 36 can also be a torsion spring, with both ends of the torsion spring fixed on the transition seat 33 and the positioning seat 34 respectively, which can also limit the rotation of the positioning seat 34. However, when installing the torsion spring, attention should be paid to the direction of rotation reset.

[0071] In some embodiments, the butterfly rib feeding device 3 further includes a bearing 37. The outer ring of the bearing 37 is fixed on the transition seat 33, and the inner ring of the bearing 37 is fixedly mounted on a rotating shaft. A positioning seat 34 is fixed to the top of the rotating shaft. The butterfly rib 102 is coaxially arranged with the rotating shaft. When the main rib 101 bends, it drives the butterfly rib 102 to be positioned accordingly, and the positioning seat 34 rotates around the rotating shaft accordingly. By setting the bearing 37 for connection, the rotational friction between the positioning seat 34 and the transition seat 33 is reduced, and the positioning seat 34 is facilitated to rotate accordingly under the drive of the butterfly rib 102.

[0072] In some embodiments, the positioning seat 34 is provided with a rotating mounting seat 38 and a support seat. Two sets of support seats are provided, located on opposite sides of the rotating mounting seat 38. These two sets of support seats can abut and limit the movement of the inner ends of the butterfly rib 102. The rotating mounting seat 38 is coaxially arranged with the rotating shaft. A U-shaped buckle 381 is provided on the rotating mounting seat 38, and the middle position of the butterfly rib 102 is elastically pressed into the U-shaped buckle 381. The opposite inner surfaces of the U-shaped buckle 381 are provided with raised ribs. When the middle position of the butterfly rib 102 is placed inside the U-shaped buckle 381, the butterfly rib 102 is pressed downwards below the raised ribs, thus limiting the butterfly rib 102 within the U-shaped buckle 381. The Z-direction height of the U-shaped buckle 381 needs to match the size of the butterfly rib 102. When the middle position of the butterfly rib 102 is engaged in the U-shaped buckle 381, both ends of the butterfly rib 102 are supported on the positioning seat 34 to achieve stable installation. The butterfly rib 102 has a first installation position and a second installation position. The installation angles of the first installation position and the second installation position differ by 90°. The installation angles of two adjacent butterfly ribs 102 differ by 90°. The U-shaped buckle 381 is suitable for installing and fixing the butterfly rib 102 in the first installation position or the second installation position, and has good versatility.

[0073] In some embodiments, the support base includes two support rods 39, which are spaced apart along the Y direction on the positioning seat 34. The distance between the two support rods 39 is adjustable to accommodate butterfly ribs 102 of various sizes, improving adaptability. The distance can be adjusted according to the size of the butterfly rib 102, ensuring tight contact and positioning between the two support rods 39 and the butterfly rib 102. Specifically, the distance between the two support rods 39 can be adjusted and fixed by providing a Y-direction elongated groove 391 at the bottom of the support rod 39, a threaded hole on the positioning seat 34, and a bolt passing through the Y-direction elongated groove 391 and threaded into the threaded hole. Preferably, each of the two support rods 39 has a guide surface 392 at its top, and the distance between the two guide surfaces 392 gradually decreases from bottom to top.

[0074] In some embodiments, the transition seat 33 is provided with a first limiting member 332, and the positioning seat 34 is provided with a second limiting member 341. When the first limiting member 332 and the second limiting member 341 abut against each other, they can limit the rotation angle and rotation direction of the positioning seat 34. The purpose of providing the first limiting member 332 and the second limiting member 341 is to limit the rotation angle and rotation direction of the positioning seat 34. Figure 10As shown, the initial state of the positioning seat 34 is when the first limiting member 332 and the second limiting member 341 abut. At this time, the positioning seat 34 can only rotate counterclockwise, and the first elastic member 35 has a small size that is compressed or extended, so that the first limiting member 332 and the second limiting member 341 elastically abut against each other, which is beneficial for installing the butterfly rib 102 when the positioning seat 34 is in this stable initial position. It can be understood that the positioning seat 34 is rotatably mounted on the transition seat 33. By setting the first limiting member 332 and the second limiting member 341, the rotation direction of the positioning seat 34 is limited. Therefore, when multiple butterfly ribs 102 are positioned with the main rib 101, the installation orientation of multiple butterfly rib feeding devices 3 needs to be set in advance to ensure that the butterfly ribs 102 can rotate with the main rib 101 when it bends.

[0075] Using the automatic forming and welding equipment for grating arches provided by this utility model, grating arches can be produced through the following methods and steps:

[0076] S1, the multiple pairs of adjusting components 5 in the adjusting arch forming device are all in the initial position;

[0077] S2, the main rib feeding device 4 simultaneously feeds two main ribs 101;

[0078] S3, the rotating frame 11 rotates 180°, and the main rib feeding device 4 simultaneously feeds the other two main ribs 101;

[0079] S4, the butterfly tendon feeding device 3 drives multiple butterfly tendons 102 to rise between the four main tendons 101 and supports the main tendons 101.

[0080] S5, multiple pairs of adjustment components 5 respectively drive four main ribs 101 to move to bend in an arc, and multiple butterfly ribs 102 follow the action of the main ribs 101.

[0081] S6, the robotic arm 2 drives the welding assembly 21 to move along the X direction to weld and fix one side of the main rib 101 and multiple butterfly ribs 102;

[0082] S7, the rotating frame 11 rotates 180°, and the welding assembly 21 moves along the X direction to weld and fix the other side of the main rib 101 and multiple butterfly ribs 102.

[0083] In the automatic forming and welding method of the grid arch frame, the main ribs 101 are fed and the grid arch frame 100 is welded on both sides by rotating the rotating frame 11. This simplifies the main rib feeding device 4 and reduces the number of welding components 21, saving costs and improving feeding and welding efficiency. Multiple butterfly ribs 102 are fed into the space between the four main ribs 101 at one time. Multiple pairs of adjusting components 5 simultaneously adjust the curvature of the four main ribs 101 and can drive the butterfly ribs 102 to follow the positioning, realizing automatic extrusion forming. This improves the positioning efficiency of the main ribs 101 and butterfly ribs 102, thereby improving the welding forming efficiency of the grid arch frame 100.

[0084] It should be noted that during the feeding process of the main ribs 101 and the butterfly ribs 102, after the four main ribs 101 are fed, the distance between the main ribs 101 can be adjusted appropriately so that the butterfly ribs 102 rise between the four main ribs 101. Then, the four main ribs 101 are adjusted into position by adjusting the adjustment component 5 so that they are aligned with the butterfly ribs 102.

[0085] The automatic forming and welding method of the grid arch frame also includes step S8, in which the first gripping component 22 on the robotic arm 2 grips the two ends of the two angle steels 103 to the main rib 101 and welds them together with the welding component 21, thus completing the forming of a grid arch frame 100.

[0086] After the welding of the grid arch 100 on one rotating frame 11 is completed in step S8, the cantilever crane 6 moves the grid arch 100 away from the rotating frame 11. Then, steps S1-S8 are repeated on the current rotating frame 11 to perform the forming process of the next grid arch 100. Two robotic arms weld the grid arch 100 on the other rotating frame 11. In this way, the grid arch 100 on the two rotating frames 11 can be formed alternately, improving the production efficiency of the grid arch 100.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
