[0067] Before practicing the embodiments of the present application, the inventors of the present application found that currently, the butt welding of two C-shaped purlins is usually carried out by manually stacking the two C-shaped purlins together first and then manually welding. This not only wastes manpower and is difficult to stack, but also has low efficiency. In addition, the welding quality is uneven and cannot be guaranteed.

[0068] Therefore, the inventors of the present application attempted to develop an automatic butt welding system that can automatically stack C-shaped purlins and automatically weld them into a butt welding assembly after production, so as to ensure production efficiency and guarantee welding quality.

[0069] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that for the sake of description, only the parts related to the present invention are shown in the drawings, rather than all the structures.

[0073] Please refer to Figure 1 As shown, the embodiment of the present application provides an automatic butt welding system, including a flipping mechanism 1, a transmission mechanism 2, and a welding device 3. The flipping mechanism 1 has a first working station and a second working station located on one side of the first working station. The flipping mechanism 1 can flip the C-shaped purlin on the first working station to the second working station. The transmission mechanism 2 includes a gripping component 21 that can move horizontally above the flipping mechanism 1 and a transporting component 22 located on one side of the flipping mechanism 1. The transporting component 22 has a stacking working station. The gripping component 21 can grip the C-shaped purlin on the first working station to the stacking working station, or the gripping component 21 can grip the C-shaped purlin on the second working station and stack it on the C-shaped purlin on the stacking working station. The welding device 3 corresponds to the transporting component 22. The welding device 3 can drive the stacked C-shaped purlins to move and perform welding. The flipping mechanism 1 is docked with the device for manufacturing C-shaped purlins. After the C-shaped purlins are manufactured, they can be directly transported to the first working station of the flipping mechanism 1. The gripping component 21 grips the C-shaped purlin on the first working station to the stacking working station. After the subsequent C-shaped purlins are transported to the first working station, the flipping mechanism 1 flips the C-shaped purlins to the second working station. The gripping component 21 grips the flipped C-shaped purlins on the second working station to the stacking working station and stacks them on the previous C-shaped purlin, thus completing the stacking of two C-shaped purlins. The transmission mechanism 2 transports the stacked two C-shaped purlins to the welding device 3. The welding device 3 drives the stacked C-shaped purlins to move and weld the stacked part of the two C-shaped purlins to complete the automatic butt welding of the two C-shaped purlins, thereby saving manpower, having high efficiency, and having uniform welding quality and high welding quality due to automatic welding.

[0074] In some embodiments of the present application, please refer to Figures 1 to 2As shown in the figure, a possible structure of the flipping mechanism 1 is that the flipping mechanism 1 includes a support frame 11, a moving component 12 disposed on one side of the support frame 11, and a flipping fork component 13 rotatably disposed at the center of the support frame 11. The first station is located on the moving component 12, and the second station is located on the other side of the support frame 11. The moving component 12 is docked with the equipment for manufacturing C-shaped purlins, and the manufactured C-shaped purlins can be directly moved onto the moving component 12. The flipping fork component 13 is rotatably arranged. The flipping fork component 13 has at least an original state, a clamping state, and a placement state. In the original state, the flipping fork component 13 is located below the moving component 12. At this time, the rotating fork component does not contact the C-shaped purlin located at the first station, and the grasping component 21 can grasp the C-shaped purlin located at the first station. In the clamping state, the flipping fork component 13 is located above the moving component 12 and forms an acute angle with the moving component 12. The C-shaped purlin is clamped on the flipping fork component 13. When the flipping fork component 13 switches from the original state to the clamping state, as the flipping fork component 13 rotates, the flipping fork component 13 first abuts against the C-shaped purlin located at the first station, and then drives the C-shaped purlin located at the first station to move to an acute angle with the first station and be clamped on the flipping fork component 13. In the placement state, the C-shaped purlin is clamped on the flipping fork component 13 and is located at the second station. At this time, the flipping of the C-shaped purlin has been realized. When the flipping fork component 13 switches from the clamping state to the placement state, the flipping fork component 13 directly drives the C-shaped purlin to rotate from an acute angle with the first station to the second station. In the clamping state, the C-shaped purlin is set to be clamped on the flipping fork component 13 in order to be able to limit the position of the C-shaped purlin and prevent it from falling off the flipping fork component 13 due to gravity during the subsequent rotation of the flipping fork component 13 driving the C-shaped purlin. When the flipping fork component 13 is in the placement state, due to the support of the second station, the C-shaped purlin will not shift. At this time, the flipping fork component 13 can return to the original state, thus completing the flipping of the C-shaped purlin.

[0075] Further, in some embodiments of the present application, please refer to Figures 1 to 2As shown, the flip fork assembly 13 includes a rotating shaft 131, a first fork 132 and a second fork 133, wherein the rotating shaft 131 can be rotatably arranged at the center of the support frame 11, a plurality of first forks 132 are evenly spaced and sleeved on the rotating shaft 131, and a plurality of second forks 133 are evenly spaced and rotatably arranged on the rotating shaft 131, that is, the first fork 132 and the second fork 133 can rotate relative to each other. The first fork 132 and the second fork 133 are respectively located on both sides of the rotating shaft 131, and the first fork 132 is located in the moving assembly 12. When the flip fork assembly 13 is in the original state, the angle between the first fork 132 and the second fork 133 is greater than 180°, and the first fork 132 is located below the moving assembly 12 to ensure that the first fork 132 does not abut against the C-shaped purlin at the first position. When the flip fork switches from the original state to the clamping state, the first fork 132 rotates in the first direction until it abuts against the C-shaped purlin, and drives the C-shaped purlin to rotate until it forms an acute angle with 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 on the flip fork assembly 13. When the flip fork assembly 13 switches from the clamping state to the placement state, the first fork 132 and the second fork 133 rotate together in 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 to the initial position toward the bottom of the moving assembly 12. The second fork 133 continues to rotate in the first direction to the bottom of the second station, realizing the flip fork assembly 13 switching from the placement state to the original state.

[0076] For ease of installation, bearing seats are usually provided at both ends of the center of the support frame 11, and bearings are provided in the bearing seats. The two ends of the rotating shaft 131 are respectively inserted into the bearings on the corresponding sides, so as to realize the relative rotation of the rotating shaft 131 relative to the support seat. If the extension line of the first fork 132 passes through the center line of the rotating shaft 131, when the flip fork assembly 13 is in the original state, since the end of the first fork 132 on one side of the rotating shaft 131 is higher than the moving assembly 12, it will interfere with the C-shaped purlin. Therefore, please refer to Figures 1 to 2 As shown, in some embodiments of the present application, the first fork 132 and the second fork 133 have the same shape. Taking the second fork 133 as an example, a possible structure of the second fork 133 is to include a sleeve 1322 and a fork rod 1321 located on one side of the sleeve 1322, the fork rod 1321 being tangent to the outer periphery of the sleeve 1322 and being located below the sleeve 1322, so that when the flip fork assembly 13 is in the original state, the fork rod 1321 is located below the moving assembly 12 and will not interfere with the moving assembly 12.

[0077] Further, in some embodiments of the present application, please refer toFigures 1 to 2 As shown, the lengths of the first fork 132 and the second fork 133 are greater than that of 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 far from the rotating shaft 131 is within the opening range of the C-shaped purlin due to the insufficient length of the first fork 132 and the problem that the first fork 132 cannot drive the C-shaped purlin to rotate.

[0078] 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, as long as it is ensured that the first fork 132 will not be blocked by the support frame 11 during rotation.

[0079] During the process of driving the C-shaped purlin to rotate, due to the heavy weight of the C-shaped purlin, the frictional force exerted by the first fork 132 and the second fork 133 on the C-shaped purlin is less than the weight of the C-shaped purlin. Therefore, when the C-shaped purlin rotates to a certain angle, it will slide towards the direction of the rotating shaft 131. As the rotation progresses, the C-shaped purlin will impact the bushing 1322 of the first fork 132 or the second fork 133, thus causing damage to the bushing 1322 and the C-shaped purlin. Therefore, in some embodiments of the present application, anti-collision members are provided on the bushings 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 rotating close to 90°, the anti-collision member can absorb the impact to ensure the safety of the C-shaped purlin and the flipping fork assembly 13.

[0080] In some embodiments of the present application, please refer to Figures 1 to 2 As shown, the support frame 11 includes a central longitudinal beam and frame bodies on both sides of the central longitudinal beam. The moving component 12 includes a first drive roller that is arranged in a rollable manner at intervals on one side frame body in sequence and an actuator that provides power for the first drive roller. The first working position is the contact surface between the first drive roller and the C-shaped purlin. A plurality of contact cross beams are arranged at intervals on the other side frame body. The contact surface of the contact cross beam is the second working position. The second working position is flush with the first working position, which can facilitate the gripping component 21 to adjust the lifting height during gripping. The actuator and the plurality of first drive rollers can be connected by a belt or a chain for power output, as long as it can be realized that the actuator drives the first drive roller to rotate. The present application does not make specific limitations.

[0081] In order to prevent the C-shaped purlin from colliding with the support frame 11 when rotating to the second working position and ensure the safety of the C-shaped purlin and the support frame 11, in some embodiments of the present application, an anti-collision pad is provided at the second working position. The anti-collision pad can be made of rubber or sponge, as long as it can buffer the impact force. The present application does not make specific limitations.

[0082] In some embodiments of the present application, please refer to Figures 1 to 2 As shown, the flipping mechanism 1 further includes a driving member 14 and a power group 15. The output end of the driving member 14 is connected to the rotating shaft 131 and can drive the rotating shaft 131 to drive the first fork 132 to rotate. The output end of the power group 15 is connected to the second fork 133 to drive the second fork 133 to rotate relative to the first fork 132. The driving member 14 can be directly connected to the rotating shaft 131 at the output end. One possible structure of the power group 15 is to include an energy supply member 313 and a transmission member. The output end of the functional member is connected to the transmission member, and the transmission member is connected to the bushing 1322 of the second fork 133 to drive the second fork 133 to rotate relative to the rotating shaft 131. A sprocket can be provided on the bushing 1322 of the second fork 133, and the transmission member can be a chain; alternatively, a pulley can be provided on the bushing 1322 of the second fork 133, and the transmission member is a belt. As long as the power transmission can be achieved, the present application does not make specific limitations.

[0083] In some embodiments of the present application, the grasping assembly 21 includes a grasping frame 211, a lifting assembly 212, and a moving claw group 213. The grasping frame 211 straddles the flipping and moving mechanism and the transmission mechanism 2. The lifting assembly 212 is movably arranged on the grasping frame 211, and the moving claw group 213 is arranged on the lifting assembly 212. The lifting assembly 212 can drive the moving claw group 213 to move along the grasping frame 211 from above the first station or the second station to above the stacking station. The moving claw group has an open state and a closed clamping state. The lifting assembly 212 can also drive the moving claw group 213 to move up and down, so as to lower the moving claw group to the first station or the second station to grasp the C-shaped purlin, or lower it to the stacking station to place the C-shaped purlin at the stacking station. One structure of the grasping frame 211 can be a moving cross beam located above the flipping and moving mechanism and the transmission mechanism 2. A guide rail is provided on the moving cross beam, and a guide block matching the guide rail is provided on the lifting assembly 212. The guide block can be slidably arranged in the guide rail, so as to realize the horizontal sliding of the lifting assembly 212 along the cross beam. One possible structure of the lifting assembly 212 is that the lifting assembly 212 includes a lifting longitudinal beam. A plurality of lifting slide rods are arranged at intervals on the lifting longitudinal beam. A through hole is provided on the guide block, and the lifting slide rods can be slidably inserted into the through hole. The lifting slide rods correspond to the through holes one by one. The up and down movement of the lifting longitudinal beam can be realized by the sliding of the lifting slide rods in the through holes. The moving claw group 213 includes a plurality of moving claws, and the plurality of moving claws are arranged at intervals on the lifting longitudinal beam. Of course, the grasping assembly 21 can also be other structures. For example, the lifting assembly 212 uses a lifting rope to realize the lifting of the moving claw group. As long as the lifting of the moving claw group 213 can be realized, and the lifting assembly 212 can drive the moving claw group to move from above the first station and the stacking station, the present application does not make specific limitations.

[0084] In the embodiments of the present application, please refer toFigures 1 to 2 As shown in the figure, a feasible structure of the transportation component 22 includes a transportation rack 221, a plurality of transportation rollers 222, and a power source 223. The plurality of transportation rollers 222 are arranged at intervals on the transportation rack 221. The output end of the power source 223 is connected to the plurality of transportation rollers 222. The connection method can be through a chain connection or a belt connection, as long as it can drive the transportation rollers 222 to rotate. The present application does not make specific limitations. The surface of the transportation roller 222 that supports the C-shaped purlin is the stacking station. After two C-shaped purlins are stacked on the stacking station, the power source 223 inputs power to the plurality of transportation rollers 222, driving the transportation rollers 222 to rotate, and thus driving the stacked C-shaped purlins to move towards the welding device 3.

[0085] In some embodiments of the present application, please refer to Figures 1 to 3 As shown in the figure, the welding device 3 includes a transportation component 31, at least two alignment components 32, and a welding torch 33. Among them, the transportation component 31 is docked with the transmission mechanism 2. There is an alignment component 32 at each end of the transportation component 31. When the C-shaped purlin moves on the transportation component 31, the alignment component 32 can limit the position of the C-shaped purlin, so that the C-shaped purlin moves in a straight line without skew or other situations. A welding torch 33 is respectively arranged on both sides of the alignment component 32 far from the transmission mechanism 2. The tip of the welding torch 33 is aligned with the gap between the two stacked C-shaped purlins. During the movement of the stacked C-shaped purlins, the welding torch 33 can weld the gap between the two C-shaped purlins, thus completing the butt welding of the two C-shaped purlins. In this process, since the transportation component 31 moves the C-shaped purlins evenly, the butt welding seam is uniform, which is not only beautiful but also can ensure the welding quality.

[0086] Specifically, in some embodiments of the present application, please refer to Figures 3 to 4 As shown in the figure, the alignment component 32 includes an alignment plate 321 and a calibration roller group 322. Among them, the center of the alignment plate 321 has a calibration hole. The stacked C-shaped purlins pass through the calibration hole. The lower hole wall of the calibration hole is lower than or flush with the supporting position of the transportation component 31 to avoid interfering with the movement of the stacked C-shaped purlins. The calibration hole can perform rough positioning and restriction on the stacked C-shaped purlins, avoiding deformation or displacement of the stacked C-shaped purlins due to the high temperature of the welding torch 33 during the welding process. Calibration roller groups 322 are respectively arranged on both sides of the calibration hole. The two calibration roller groups 322 can move towards each other to abut against the stacked C-shaped purlins, so as to perform fine positioning and restriction on the C-shaped purlins. The setting of the two alignment components 32 limits both ends of the part of the two stacked C-shaped purlins located inside the welding device 3 during the process of passing through the welding device 3, enabling them to remain stable during welding to ensure good welding quality.

[0087] As the two C-shaped purlins after stacking are driven by the conveying component 31, if there is friction between the alignment roller group 322 and the C-shaped purlin, it will hinder the movement of the C-shaped purlin. Therefore, please refer to Figures 3 to 4 As shown, in the embodiment of the present application, the alignment roller group 322 in the embodiment of the present application is in sliding contact with the two stacked C-shaped purlins to avoid the influence of friction while ensuring the alignment effect.

[0088] Specifically, in some embodiments of the present application, please refer to Figures 3 to 4 As shown, a feasible structure of the alignment roller group 322 is that the alignment roller group 322 includes a moving plate 3221, an alignment roller 3222, and a power component 3223. The moving plate 3221 is movably arranged on the side of the alignment hole towards the alignment hole, the alignment roller 3222 is rotatably arranged on the side of the moving plate 3221 facing the alignment hole, the alignment roller 3222 can be in contact with the C-shaped purlin, and the output end of the power component 3223 is connected to the moving plate 3221. The power component 3223 can drive the moving plate 3221 to move towards the alignment hole to make the alignment roller 3222 contact with the C-shaped purlin, or drive the moving plate 3221 to move away from the alignment hole. After the alignment roller 3222 contacts the C-shaped purlin, as the C-shaped purlin moves with the conveying component 31, the alignment roller 3222 also rotates, so that it can not only play a limiting role but also reduce the friction between the alignment roller 3222 and the C-shaped purlin.

[0089] During the welding process of the stacked C-shaped purlins, they may not only move in the left-right direction but also deform in the vertical direction. Therefore, in order to avoid the influence of deformation in the vertical direction, in some embodiments of the present application, the alignment roller group 322 can move up and down on the upper side of the alignment hole, and the upper alignment roller 3222 can move up and down to press or loosen the stacked C-shaped purlins.

[0090] It should be noted that the alignment roller group 322 is located on the side away from the alignment hole before the stacked C-shaped purlins pass through the alignment hole, and the alignment roller group 322 only moves towards the C-shaped purlin to contact it after the C-shaped purlin passes through the alignment hole, so as to avoid interfering with the C-shaped purlin passing through the alignment hole.

[0091] During the welding process, the welding torch 33 generates high temperature, so heat dissipation is required. If the welding torch 33 is set in a place where parts are concentrated, the heat dissipation effect will surely be poor. Therefore, please refer to Figures 3 to 4 As shown, in the embodiment of the present application, the welding torch 33 and the alignment roller group 322 measured in the horizontal 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 concentration of components.

[0092] Furthermore, in some embodiments of the present application, please refer to Figures 3 to 4As shown in the figure, the welding torch 33 is arranged on the side of the alignment plate 321 away from the conveying assembly 31. There is no obstruction during the welding process of the welding torch 33, which is convenient for the operator to observe the welding situation of the welding torch 33 and is conducive to the control of the weld quality. The alignment roller set 322 above the alignment hole is located on the side of the moving plate 3221 away from the conveying assembly 31. It can not only avoid interference with the alignment roller sets 322 on the lateral sides of the alignment hole, but also, compared with arranging the upper alignment roller set 322 on the side facing the conveying assembly 31, arranging the upper alignment roller 3222 on the side of the alignment plate 321 facing away from the conveying assembly 31 can better restrict the shape of the stacked C-shaped purlins under the action of the upper alignment rollers 3222 at both ends of the conveying assembly 31.

[0093] The C-shaped purlins have different models, and the heights of different models of C-shaped purlins are different. Then the gap positions after stacking different models of C-shaped purlins are different, and the positions of the welding torch 33 are different. Therefore, in some embodiments of the present application, please refer to Figures 3 to 4 As shown in the figure, the welding torch 33 is slidably arranged on the alignment plate 321 in the vertical direction. The position of the welding torch 33 can be adjusted by sliding in the vertical direction to meet the fillet welding requirements of different models of C-shaped purlins. The slidable structure of the welding torch 33 can be that the welding torch 33 is provided with a slider, and the alignment plate 321 is provided with a slideway, and the slider can be slidably arranged in the slideway. Of course, it can also be other structures, as long as it can realize the up and down movement of the welding torch 33 to adjust the position. The present application does not make specific limitations.

[0094] It should be noted that the welding torch 33 is only arranged on the alignment assembly 32 on the side away from the transmission mechanism 2, and the welding torch 33 is not arranged on the alignment assembly 32 facing the transmission mechanism 2.

[0095] The alignment plate 321 plays a supporting role for the alignment roller set 322 and the welding torch 33 on the welding equipment 3. Therefore, the higher the strength of the alignment plate 321, the better. Therefore, in some embodiments of the present 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 an external force, the external force is more evenly distributed on the surface of the alignment plate 321, and it can better maintain the integrity of the shape and structure.

[0096] In some embodiments of the present application, please refer to Figure 3As shown, the conveying assembly 31 includes a conveying frame 311, a plurality of rotating rollers 312 spaced apart on the conveying frame 311, and a power supply member 313 whose output end is connected to the driving roller. The power supply member 313 can provide power for the driving roller to rotate. The stacked C-shaped steel is supported on the driving roller and moves along the conveying frame 311 under the action of the frictional force with the driving roller. The connection manner between each driving roller and the functional member can be that the conveying assembly 31 further includes a plurality of sprockets and chains. Sprockets are sleeved on the output end of the functional member and the end of the driving roller, and the chain meshes with the plurality of sprockets to transmit the power of the power supply member to each driving roller. It can also be achieved by a combination of a belt and a pulley to transmit power, as long as the power of the power supply member 313 can be transmitted to each driving roller. The present application does not make specific limitations.

[0097] The power member 3223, the driving member 14, the power source 223, the power supply member 313, and the actuator in the present application can be a kind of motor such as a rotating motor or a moving motor, as long as it can provide power. The present application does not make specific limitations.

[0098] The embodiment of the present application also provides an automatic butt welding method, which is to perform automatic butt welding on the C-shaped purlin by applying the above automatic butt welding system. The automatic butt welding method includes:

[0101] S30. The transmission mechanism 2 moves the C-shaped purlin located at the second station to be stacked on the first C-shaped purlin, and transports the stacked C-shaped purlins to the welding device 3;

[0102] S40. The welding device 3 drives the C-shaped purlin to move and welds at the abutting gap between the two C-shaped purlins.

[0103] In some embodiments of the present 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; includes:

The lifting vertical beam moves downward along the through hole until the moving claws place the first C-shaped purlin on the stacking station or stack the second C-shaped purlin on the first C-shaped purlin. After the moving claws open, the lifting vertical beam moves upward along the through hole to separate from the C-shaped purlin, thus completing the stacking process of two adjacent C-shaped purlins. During this process, the transport rollers 222 on the transport assembly 22 do not rotate and only start to rotate after the stacking of two adjacent C-shaped purlins is completed to convey the stacked two C-shaped purlins to the welding device 3.
