Description

Technical Field

[0001] This invention relates to the field of automatic welding equipment technology, and more particularly to automatic welding equipment. Background Technology

[0002] The welded assembly formed by two C-shaped purlins exhibits better stability, increases the cross-sectional area and moment of inertia of the component, thereby improving its bending, shear, and compressive strength. Therefore, welded assemblies of two C-shaped purlins are widely used in structural building construction, cranes, transport aircraft, and other large mechanical equipment.

[0003] The existing C-shaped purlin welding assembly is often manufactured by manual welding by workers, which not only consumes a lot of manpower, but also results in unstable welding quality, low efficiency, and difficulty in meeting the needs of large-scale production. Utility Model Content

[0004] In view of the above problems, embodiments of the present invention are proposed. The purpose of the embodiments of the present invention is to provide an automatic welding device that can automatically weld two C-shaped purlins stacked one on top of the other.

[0005] To achieve this objective, the embodiments of the present invention adopt the following technical solutions:

[0006] An automatic welding device, comprising:

[0007] The conveying assembly supports two stacked C-shaped purlins, which can automatically move the two stacked C-shaped purlins.

[0008] An alignment component, disposed on the transport component, has alignment holes. Two C-shaped purlins stacked vertically pass through the alignment holes. The lower wall of the alignment hole is lower than or flush with the support position of the transport component.

[0009] A welding torch is adjustablely positioned on the alignment assembly. The torch tip is aligned with the gap between the two stacked C-shaped purlins. The two welding torches are respectively positioned on both sides of the alignment hole.

[0010] Optionally, the alignment components are multiple, with one alignment component at each end of the transport component;

[0011] The welding torch is located on the downstream conveying component along the direction of movement.

[0012] Optionally, the alignment component includes:

[0013] Alignment plate, with the alignment hole in the center;

[0014] The calibration roller group is provided on both sides of the calibration hole in the transverse direction. The two calibration roller groups can move towards each other to abut against the C-shaped purlin, or move away from each other to separate from the C-shaped purlin.

[0015] Optionally, the alignment plate has a slide rail on its side facing away from the transport assembly along the vertical direction, and the welding gun has a slider that is slidably disposed within the slide rail.

[0016] Alternatively, the alignment plate may be circular.

[0017] Alternatively, the alignment roller group, arranged laterally, is located on the side of the alignment plate facing the transport assembly.

[0018] Optionally, a calibration roller group may be provided on the upper side of the calibration hole, which can be moved up and down.

[0019] Optionally, the calibration roller set includes:

[0020] A movable plate is laterally positioned to the side of the alignment hole;

[0021] A calibration roller, rotatably mounted on the side of the movable plate facing the calibration hole, is capable of abutting against the C-shaped purlin; and

[0022] The power component has its output end connected to the movable plate.

[0023] Optionally, the transport component includes:

[0024] Transport rack;

[0025] Multiple rotating rollers are evenly spaced on the conveyor frame; and

[0026] The power supply component has its output end connected to multiple of the rotating rollers.

[0027] Optionally, the transport component further includes:

[0028] The sprocket is fitted onto both the output end of the power supply component and the end of the rotating roller;

[0029] A chain that meshes with a plurality of said sprockets.

[0030] The technical solution provided by this invention involves providing alignment holes on the alignment component. Two stacked C-shaped purlins pass through these holes, with the lower wall of the alignment hole being lower than or flush with the support position of the transport component, thus preventing obstruction of the C-shaped purlins from moving with the transport component. The alignment holes enable positional calibration of the two stacked C-shaped purlins. Welding torches are located on both sides of the alignment holes on the alignment component, with the torch tips aligned with the corresponding joint gaps of the two C-shaped purlins. As the transport component moves the two stacked C-shaped purlins, the welding torches on both sides weld the corresponding joint gaps, achieving automatic welding of the C-shaped purlins. This saves manpower, is highly efficient, and produces uniform and good welding quality. Attached Figure Description

[0040] Before implementing the embodiments of this application, the inventors discovered that the welding of two C-shaped purlins (or C-shaped steel, hereinafter referred to as C-shaped purlins) is usually done manually by first stacking the two C-shaped purlins together and then welding them manually. This is not only wasteful of manpower and difficult to stack, but also inefficient. In addition, the welding quality is inconsistent and cannot be guaranteed.

[0041] Therefore, the inventors of this application sought to develop an automated welding system that enables C-shaped purlins to be automatically stacked and welded into welded assemblies after production, in order to ensure production efficiency and welding quality.

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0046] Please refer to Figure 1 As shown in the illustration, this application provides an automatic welding system, including a flipping mechanism 1, a conveying mechanism 2, and a welding device 3. The flipping mechanism 1 has a first station and a second station located to one side of the first station. The flipping mechanism 1 can flip C-shaped purlins from the first station to the second station. The conveying mechanism 2 includes a gripping component 21 that can move laterally above the flipping mechanism 1 and a transport component 22 located to one side of the flipping mechanism 1. The transport component 22 has a stacking station. The gripping component 21 can grip the C-shaped purlins from the first station to the stacking station, or the gripping component 21 can grip the C-shaped purlins from the second station and stack them on top of the C-shaped purlins at the stacking station. The welding device 3 corresponds to the transport component 22 and can move the stacked C-shaped purlins for welding. The flipping mechanism 1 connects to the equipment for manufacturing C-shaped purlins. After the C-shaped purlins are manufactured, they can be directly transported to the first station of the flipping mechanism 1. The gripping component 21 grips the C-shaped purlins at the first station and moves them to the stacking station. After subsequent C-shaped purlins are transported to the first station, the flipping mechanism 1 flips them to the second station. The gripping component 21 then grips the flipped C-shaped purlins at the second station and moves them to the stacking station, stacking them on top of the previous C-shaped purlin, thus completing the stacking of two C-shaped purlins. The transmission mechanism 2 transports the two stacked C-shaped purlins to the welding equipment 3. The welding equipment 3 moves the stacked C-shaped purlins and welds the overlapping area of ​​the two C-shaped purlins to complete the automated welding of the two C-shaped purlins, thus saving manpower, increasing efficiency, and ensuring uniform and high-quality welding due to the automated welding process.

[0047] Please refer to some embodiments of this application. Figures 1-2As shown, one possible structure of the flipping mechanism 1 is as follows: the flipping mechanism 1 includes a support frame 11, a movable component 12 disposed on one side of the support frame 11, and a flipping fork assembly 13 rotatably disposed in the center of the support frame 11. A first workstation is located on the movable component 12, and a second workstation is located on the other side of the support frame 11. The movable component 12 is connected to the equipment for manufacturing C-shaped purlins, and the manufactured C-shaped purlins can be directly moved onto the movable component 12. The flipping fork assembly 13 is rotatably disposed and has at least an original state, a gripping state, and a placement state. In the original state, the flipping fork assembly 13 is located below the movable component 12. At this time, the rotating fork assembly does not contact the C-shaped purlin located at the first workstation, and the gripping component 21 can grip the C-shaped purlin located at the first workstation. When in the clamping state, the flip fork assembly 13 is located above the moving assembly 12 and forms an acute angle with the moving assembly 12. The C-shaped purlin is clamped on the flip fork assembly 13. When the flip fork assembly 13 switches from the original state to the clamping state, as the flip fork assembly 13 rotates, the flip fork assembly 13 first abuts against the C-shaped purlin located at the first station, and then drives the C-shaped purlin at the first station to move to form an acute angle with the first station and clamp on the flip fork assembly 13. When in the placement state, the C-shaped purlin is clamped on the flip fork assembly 13 and located at the second station. At this time, the flipping operation of the C-shaped purlin has been realized. When the flip fork assembly 13 switches from the clamping state to the placement state, the flip fork assembly 13 directly rotates the C-shaped purlin from the acute angle with the first station to the second station. In the clamping state, the C-shaped purlin is clamped onto the flip fork assembly 13 to restrict its position and prevent it from falling off the assembly due to gravity during the subsequent rotation of the C-shaped purlin by the flip fork assembly 13. When the flip fork assembly 13 is in the placement state, the C-shaped purlin will not shift due to the support of the second station. At this time, the flip fork assembly 13 can return to its original state, thereby completing the flipping of the C-shaped purlin.

[0048] Furthermore, in some embodiments of this application, please refer to Figures 1-2As shown, the flip fork assembly 13 includes a rotating shaft 131, a first fork 132, and a second fork 133. The rotating shaft 131 is rotatably disposed in the center of the support frame 11. Multiple first forks 132 are evenly spaced and sleeved on the rotating shaft 131. Multiple second forks 133 are also evenly spaced and rotatably disposed on the rotating shaft 131, meaning the first forks 132 and second forks 133 can rotate relative to each other. The first forks 132 and second forks 133 are located on opposite sides of the rotating shaft 131, with the first forks 132 located within the moving assembly 12. When the flip fork assembly 13 is in its original state, the angle between the first forks 132 and second forks 133 is greater than 180°. The first forks 132 are located below the moving assembly 12 to ensure that the first forks 132 do not abut against the C-shaped purlin at the first position. When switching from the original state to the clamping state between the flip forks, the first fork 132 rotates along the first direction until it abuts against the C-shaped purlin, causing the C-shaped purlin to rotate at an acute angle to the moving assembly 12. At this time, the second fork 133 rotates in the opposite direction of the first direction until it abuts against the C-shaped purlin, thereby clamping the C-shaped purlin onto the flip fork assembly 13. When switching from the clamping state to the placement state, the first fork 132 and the second fork 133 rotate together along the first direction until the C-shaped purlin abuts against the side of the support clamp away from the moving assembly 12. The C-shaped purlin is supported at the second station. At this time, the first fork 132 rotates in the opposite direction of the first direction to the moving assembly 12 and rotates downward toward the moving assembly 12 to the initial position. The second fork 133 continues to rotate along the first direction to below the second station, thereby switching the flip fork assembly 13 from the placement state to the original state.

[0049] For ease of installation, bearing seats are typically provided at both ends of the center of the support frame 11, with bearings inside each seat. The two ends of the rotating shaft 131 are respectively inserted into the bearings on their respective sides, thus enabling relative rotation of the rotating shaft 131 relative to the support seat. If the extension line of the first shift fork 132 passes through the center line of the rotating shaft 131, when the flipping shift fork assembly 13 is in its original state, the end of the first shift fork 132 located on one side of the rotating shaft 131 will be higher than the moving assembly 12, causing interference with the C-shaped purlin. Therefore, please refer to... Figures 1-2 As shown, in some embodiments of this application, the first shift fork 132 and the second shift fork 133 have the same shape. Taking the second shift fork 133 as an example, one possible structure of the second shift fork 133 is that it includes a bushing 1322 and a fork 1321 located on one side of the bushing 1322. The fork 1321 is tangent to the outer periphery of the bushing 1322 and is located below the bushing 1322. In this way, when the flipping shift fork assembly 13 is in its original state, the fork 1321 is located below the moving assembly 12 and will not interfere with the moving assembly 12.

[0050] Furthermore, in some embodiments of this application, please refer to Figures 1-2 As shown, the lengths of the first fork 132 and the second fork 133 are greater than the C-shaped purlin and less than or equal to the width of the moving component 12. This ensures that the first fork 132 can fully drive the C-shaped purlin to rotate, avoiding the problem that the end of the first fork 132 away from the pivot 131 is located within the opening range of the C-shaped purlin due to insufficient length, thus preventing the first fork 132 from failing to drive the C-shaped purlin to rotate.

[0051] It should be noted that the length of the first fork 132 is approximately the same as the width of the moving component 12. Even if the length of the first fork 132 is less than the width of the moving component 12, it is acceptable as long as the first fork 132 is not blocked by the support frame 11 during rotation.

[0052] During the rotation of the C-shaped purlin, due to its relatively heavy weight, the frictional force exerted by the first fork 132 and the second fork 133 on the C-shaped purlin is less than its weight. Therefore, when the C-shaped purlin rotates to a certain angle, it will slide towards the rotating shaft 131. As the rotation continues, the C-shaped purlin will collide with the bushing 1322 of the first fork 132 or the second fork 133, thereby damaging the bushing 1322 and the C-shaped purlin. Therefore, in some embodiments of this application, anti-collision members are provided on the bushing 1322 of the first fork 132 and the second fork 133. When the C-shaped purlin slides along the first fork 132 or the second fork 133 when it rotates to nearly 90°, it collides with the anti-collision members. The anti-collision members can absorb the impact, thereby ensuring the safety of the C-shaped purlin and the flipping fork assembly 13.

[0053] Please refer to some embodiments of this application. Figures 1-2 As shown, the support frame 11 includes a central longitudinal beam and frame bodies located on both sides of the central longitudinal beam. The moving component 12 includes first transmission rollers that are sequentially and rotatably arranged on one side of the frame body and an actuator that provides power to the first transmission rollers. The first station is the contact surface between the first transmission rollers and the C-shaped purlins. Multiple abutment beams are spaced apart on the other side of the frame body. The contact surface of the abutment beams is the second station. The second station is flush with the first station, which facilitates the adjustment of the lifting height of the gripping component 21 during gripping. The actuators and the multiple first transmission rollers can be connected by belts or chains for power output. As long as the actuators can drive the first transmission rollers to rotate, this application does not impose specific limitations.

[0054] To prevent the C-shaped purlin from colliding with the support frame 11 when it rotates to the second station and to ensure the safety of the C-shaped purlin and the support frame 11, in some embodiments of this application, an anti-collision pad is provided at the second station. The anti-collision pad can be made of rubber or sponge material, as long as it can buffer the impact force. This application does not make any specific limitation.

[0055] Please refer to some embodiments of this application. Figures 1-2 As shown, the flipping mechanism 1 also includes a drive member 14 and a power unit 15. The output end of the drive member 14 is connected to the rotating shaft 131, enabling the rotating shaft 131 to drive the first shift fork 132 to rotate. The output end of the power unit 15 is connected to the second shift fork 133 to drive the second shift fork 133 to rotate relative to the first shift fork 132. The drive member 14 may have its output end directly connected to the rotating shaft 131. One possible structure of the power unit 15 includes a power supply member 313 and a transmission member. The output end of the power supply member is connected to the transmission member, and the transmission member is connected to the bushing 1322 of the second shift fork 133 to drive the second shift fork 133 to rotate relative to the rotating shaft 131. The bushing 1322 of the second shift fork 133 may be equipped with a sprocket, and the transmission member may be a chain; alternatively, the bushing 1322 of the second shift fork 133 may be equipped with a pulley, and the transmission member may be a belt. As long as power transmission can be achieved, this application does not impose specific limitations.

[0056] In some embodiments of this application, the gripping component 21 includes a gripping frame 211, a lifting component 212, and a movable claw assembly 213. The gripping frame 211 is straddling the flipping and moving mechanism and the transmission mechanism 2. The lifting component 212 is movably mounted on the gripping frame 211, and the movable claw assembly 213 is mounted on the lifting component 212. The lifting component 212 can drive the movable claw assembly 213 to move along the gripping frame 211 from above the first or second workstation and above the stacking workstation. The movable claw assembly has an open state and a closed gripping state. The lifting component 212 can also drive the movable claw assembly 213 to move up and down, so as to lower the movable claw assembly to the first or second workstation to grip the C-shaped purlin, or to lower it to the stacking workstation to place the C-shaped purlin at the stacking workstation. One structure of the gripper 211 can be a moving crossbeam located above the flipping and moving mechanism and the transmission mechanism 2. The moving crossbeam has a guide rail, and the lifting assembly 212 has a guide block that matches the guide rail. The guide block is slidably disposed in the guide rail, thereby enabling the lifting assembly 212 to slide laterally along the crossbeam. Another possible structure for the lifting assembly 212 is that it includes a lifting longitudinal beam with multiple lifting slide rods spaced apart on it. The guide block has through holes, and the lifting slide rods can slide through these holes. Each lifting slide rod corresponds to one of the through holes, and the vertical movement of the lifting longitudinal beam is achieved by sliding the lifting slide rods within the through holes. The moving claw assembly 213 includes multiple moving claws, which are spaced apart on the lifting longitudinal beam. Of course, the gripping component 21 can also be other structures, such as the lifting component 212 using a lifting rope to realize the lifting of the mobile gripping group, as long as the mobile gripping group 213 can be lifted and lowered, and the lifting component 212 can drive the mobile gripping group to move from the first work station and the stacking work station, this application does not make specific limitations.

[0057] In the embodiments of this application, please refer to Figures 1-2 As shown, one possible structure of the transport assembly 22 includes a transport frame 221, multiple transport rollers 222, and a power source 223. The multiple transport rollers 222 are spaced apart on the transport frame 221. The output end of the power source 223 is connected to the multiple transport rollers 222. The connection can be via a chain or a belt, as long as it can drive the transport rollers 222 to rotate; this application does not impose any specific limitations. The surface of the transport rollers 222 that supports the C-shaped purlins is a stacking station. After two C-shaped purlins are stacked on the stacking station, the power source 223 inputs power to the multiple transport rollers 222, driving the transport rollers 222 to rotate, thereby driving the stacked C-shaped purlins to move towards the welding equipment 3.

[0058] Please refer to some embodiments of this application. Figures 1-3 As shown, the welding equipment 3 includes a conveying component 31, at least two alignment components 32, and a welding torch 33. The conveying component 31 is connected to the transmission mechanism 2. Each end of the conveying component 31 has an alignment component 32. When the C-shaped purlin moves on the conveying component 31, the alignment component 32 restricts the position of the C-shaped purlin, ensuring it moves in a straight line without skewing. A welding torch 33 is located on each side of the alignment component 32, away from the transmission mechanism 2. The torch tip aligns with the gap between the two stacked C-shaped purlins. During the movement of the stacked C-shaped purlins, the welding torch 33 welds the gap between the two C-shaped purlins, thus completing the weld between the two C-shaped purlins. Because the conveying component 31 moves the C-shaped purlins uniformly, the weld is uniform, resulting in both aesthetic appeal and high welding quality.

[0059] Specifically, in some embodiments of this application, please refer to Figures 3-4 As shown, the alignment component 32 includes an alignment plate 321 and a set of alignment rollers 322. The alignment plate 321 has an alignment hole in the center, through which the stacked C-shaped purlins pass. The lower wall of the alignment hole is lower than or flush with the support position of the transport component 31 to avoid interfering with the movement of the stacked C-shaped purlins. The alignment hole can provide coarse positioning and restriction for the stacked C-shaped purlins, preventing deformation or displacement caused by the high temperature of the welding torch 33 during welding. Alignment rollers 322 are provided on both sides of the alignment hole. The two alignment rollers 322 can move towards each other to abut against the stacked C-shaped purlins, thereby providing fine positioning and restriction for the C-shaped purlins. The arrangement of the two alignment components 32 ensures that both ends of the portions of the two stacked C-shaped purlins within the welding equipment 3 are limited during the welding process, maintaining stability during welding and ensuring good welding quality.

[0060] As the two stacked C-shaped purlins are driven by the conveyor assembly 31, friction between the alignment roller group 322 and the C-shaped purlins will hinder their movement. Therefore, please refer to... Figures 3-4 As shown, in this embodiment of the application, the calibration roller group 322 slides against the two stacked C-shaped purlins to ensure the calibration effect while avoiding the influence of friction.

[0061] Specifically, in some embodiments of this application, please refer to Figures 3-4 As shown, one possible structure of the calibration roller group 322 is that the calibration roller group 322 includes a movable plate 3221, a calibration roller 3222, and a power member 3223. The movable plate 3221 is movable toward the calibration hole and is disposed to the side of the calibration hole. The calibration roller 3222 is rotatably disposed on the side of the movable plate 3221 toward the calibration hole. The calibration roller 3222 can abut against the C-shaped purlin. The output end of the power member 3223 is connected to the movable plate 3221. The power unit 3223 can drive the moving plate 3221 to move toward the alignment hole to bring the alignment roller 3222 into contact with the C-shaped purlin, or drive the moving plate 3221 to move away from the alignment hole. After the alignment roller 3222 comes into contact with the C-shaped purlin, as the C-shaped purlin moves with the conveying component 31, the alignment roller 3222 also rotates, which not only plays a limiting role but also reduces the friction between the alignment roller 3222 and the C-shaped purlin.

[0062] During the welding process, the stacked C-shaped purlins may move in the left and right directions and may also deform in the vertical direction. Therefore, in order to avoid the influence of deformation in the vertical direction, in some embodiments of this application, a calibration roller group 322 is movable up and down on the upper side of the calibration hole. The calibration roller 3222 located on the upper side can move up and down to press or loosen the stacked C-shaped purlins.

[0063] It should be noted that before the stacked C-shaped purlins pass through the alignment holes, the alignment roller group 322 is located on the side away from the alignment holes. Only after the C-shaped purlins pass through the alignment holes will the alignment roller group 322 move toward the C-shaped purlins to abut against them, thereby avoiding interference with the C-shaped purlins passing through the alignment holes.

[0064] During the welding process, the welding torch 33 generates high temperatures, thus requiring heat dissipation. Placing the welding torch 33 in areas where parts are clustered will inevitably result in poor heat dissipation. Therefore, please refer to... Figures 3-4 As shown, in the embodiments of this application, the welding gun 33 and the alignment roller group 322, which are located in the lateral direction of the alignment hole, are respectively arranged on both sides of the alignment plate 321 to avoid the problem of poor heat dissipation caused by excessive accumulation of components.

[0065] Furthermore, in some embodiments of this application, please refer to Figures 3-4As shown, the welding torch 33 is positioned on the side of the alignment plate 321 away from the transport component 31. The welding torch 33 is unobstructed during welding, allowing the operator to easily observe its welding process, which is beneficial for weld quality control. The alignment roller group 322, located above the alignment hole, is situated on the side of the moving plate 3221 away from the transport component 31. This not only avoids interference with the alignment roller groups 322 on both sides of the alignment hole, but also, compared to placing the upper alignment roller group 322 on the side of the alignment plate 321 away from the transport component 31, the upper alignment roller 3222, positioned on the side of the alignment plate 321 away from the transport component 31, better restricts the shape of the stacked C-shaped purlins under the action of the upper alignment rollers 3222 located at both ends of the transport component 31.

[0066] C-shaped purlins come in different models, and the heights of these models vary. Therefore, the gap positions after stacking different models of C-shaped purlins differ, and consequently, the positions of the welding torch 33 also differ. Therefore, in some embodiments of this application, please refer to... Figures 3-4 As shown, the welding torch 33 can be slidably mounted on the alignment plate 321 in a vertical direction. The position of the welding torch 33 can be adjusted by sliding it vertically to meet the welding requirements of different types of C-shaped purlins. The sliding structure of the welding torch 33 can be such that the welding torch 33 has a slider, and the alignment plate 321 has a slide rail in a vertical direction, with the slider slidably mounted in the slide rail. Of course, other structures are also possible, as long as the welding torch 33 can move up and down to adjust its position. This application does not impose any specific limitations.

[0067] It should be noted that the welding torch 33 is provided only on the alignment component 32 on the side away from the transmission mechanism 2, while the welding torch 33 is not provided on the alignment component 32 facing the transmission mechanism 2.

[0068] The alignment plate 321 serves to support the alignment roller group 322 and the welding gun 33 on the welding equipment 3. Therefore, the higher the strength of the alignment plate 321, the better. Thus, in some embodiments of this application, the shape of the alignment plate 321 is set to be circular. Compared with a rectangle, the circular alignment plate 321 has higher symmetry and stability. When subjected to external force, the external force is more evenly distributed on the surface of the alignment plate 321, which can better maintain the integrity of the shape and structure.

[0069] In some embodiments of the application itself, please refer to Figure 3As shown, the conveying assembly 31 includes a conveying frame 311, multiple rotating rollers 312 spaced apart on the conveying frame 311, and a power supply component 313 connected to the output end of the drive roller. The power supply component 313 can provide power to rotate the drive roller. The stacked C-shaped purlins are supported on the drive roller and move along the conveying frame 311 under the action of friction with the drive roller. The connection between each drive roller and the functional component can be as follows: the conveying assembly 31 also includes multiple sprockets and chains. The output end of the functional component and the end of the drive roller are both fitted with sprockets. The chain meshes with multiple sprockets to transmit the power of the power supply component to each drive roller. Alternatively, power can be transmitted through a combination of belts and pulleys. As long as the power of the power supply component 313 can be transmitted to each drive roller, this application does not impose any specific limitations.

[0070] The power component 3223, drive component 14, power source 223, power supply component 313, and actuator of this application can be any type of motor such as a rotary motor or a mobile motor, as long as it can provide power. This application does not make any specific limitations.

[0071] This application also provides an automatic welding method, which involves automatically welding C-shaped purlins using the aforementioned automatic welding system. The automatic welding method includes:

[0072] S10, the first C-shaped purlin moves to the first station, and the transmission mechanism 2 moves the C-shaped purlin to the stacking station;

[0073] S10, the second C-shaped purlin moves to the first station, and the flipping mechanism 1 flips the C-shaped purlin to the second station;

[0074] S30, the transfer mechanism 2 moves the C-shaped purlin located at the second station to the first C-shaped purlin for stacking, and transports the stacked C-shaped purlin to the welding equipment 3;

[0075] S40, Welding equipment 3 moves the C-shaped purlins and welds the joint between the two C-shaped purlins.

[0076] In some embodiments of this application, S10, the second C-shaped purlin moves to the first station, and the flipping mechanism 1 flips the C-shaped purlin to the second station; including:

[0077] S11, the first shift fork 132 drives the C-shaped purlin on the first station to rotate along the first direction to form an acute angle with the first station;

[0078] S12, the second fork 133 rotates in the opposite direction of the first direction until it abuts against the C-shaped purlin. At this time, the C-shaped purlin is located between the first fork 132 and the second fork 133, and the flip fork assembly 13 is in the clamping state.

[0079] S13, the first shift fork 132 and the second shift fork 133 rotate simultaneously along the first direction until the C-shaped purlin is placed on the second work station, and the flipping shift fork assembly 13 is in the placement state;

[0080] S14, the second shift fork 133 and the first shift fork 132 return to their original positions, and the flip shift fork assembly 13 restores its original state.

[0081] After the first C-shaped purlin moves to the first station, or after the second C-shaped purlin flips to the second station, the moving claw opens, and the lifting longitudinal beam moves downward along the through hole until the moving claw reaches the gripping position. After the moving claw grips the C-shaped purlin, the lifting longitudinal beam moves upward along the through hole until the C-shaped purlin is separated from the first station. The lifting assembly 212 moves laterally along the moving crossbeam to move the C-shaped purlin above the stacking station. The lifting longitudinal beam moves downward along the through hole until the moving claw places the first C-shaped purlin on the stacking station, or stacks the second C-shaped purlin on top of the first C-shaped purlin. After the moving claw opens, the lifting longitudinal beam moves upward along the through hole until it separates from the C-shaped purlin, thus completing the stacking process of two adjacent C-shaped purlins. During this process, the transport roller 222 on the transport component 22 does not rotate. It only starts to rotate after the two adjacent C-shaped purlins are stacked, so as to transport the two stacked C-shaped purlins to the welding equipment 3.

[0082] When the stacked C-shaped purlins are delivered to the welding equipment 3, in some embodiments of this application, S40, the welding equipment 3 moves the C-shaped purlins and welds the abutment joint of the two C-shaped purlins. This includes:

[0083] S41, the rotating roller 312 on the conveying component 31 rotates, causing the stacked C-shaped purlins to pass through the alignment hole;

[0084] S42, the alignment roller group 322 moves toward the C-shaped purlin until the alignment roller 3222 comes into contact with the C-shaped purlin, and rotates during the movement of the C-shaped purlin;

[0085] S43. Move the welding gun 33 vertically and adjust its position so that the tip of the welding gun 33 is aligned with the butt joint of the two stacked C-shaped purlins, and start the welding gun 33.

[0086] S44, the conveying component 31 drives the C-shaped purlin to be transported through the welding equipment 3 to complete the welding.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
