[0049] The application will be further described below with reference to the drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the application described below can be combined with each other as long as there is no conflict. The embodiments described below with reference to the drawings are exemplary and are intended to explain the application, and cannot be understood as limiting the application.

[0050] As shown in Figures 1 to 2 The present disclosure provides an automatic welding device 1, comprising a first bin 2, a second bin 3, a first horizontal pushing member 4, a first vertical pushing member 5, a second horizontal pushing member 6, and a second vertical pushing member 7.

[0051] In the embodiments of the present disclosure, the first bin 2 is used to store a to-be-welded structural member 9, and the first bin 2 has a first discharging end. After the to-be-welded structural member 9 moves to the first discharging end, the to-be-welded structural member 9 can fall into the second bin 3 under the pushing of the first vertical pushing member 5.

[0052] In the embodiments of the present disclosure, the to-be-welded structural member 9 can be placed in the first bin 2 in an artificial stacking manner, and a plurality of to-be-welded structural members 9 can be stacked in the first bin 2 at one time.

[0053] As shown in Figure 3 In some embodiments, a plurality of first guide members 21 can be arranged in the first bin 2 in an array interval manner. The first guide members 21 extend along the longitudinal direction Y, and the top surface of the first guide members 21 abuts against the to-be-welded structural member 9.

[0054] For example, two first guide members 21 arranged in an array spaced apart can be provided in the first hopper 2. The length of the first guide member 21 in the longitudinal Y direction can be equal to the length of the first hopper 2 in the longitudinal Y direction. The bottom surface of the structural component 9 to be welded abuts against the top surface of the two first guide members 21. Compared with the scheme in which the structural component 9 to be welded is in complete contact with the bottom surface of the first hopper 2, the embodiment of this disclosure can reduce the friction surface when the structural component 9 to be welded moves in the first hopper 2, thereby reducing the friction force on the structural component 9 to be welded and the first hopper 2, thereby reducing the possibility of damage to the structural component 9 to be welded and the first hopper 2, and extending the service life of the structural component 9 to be welded and the first hopper 2. The two first guide members 21 can be symmetrically arranged about the central axis of the first hopper 2 in the longitudinal Y direction to form a uniform and stable support for the structural component 9 to be welded.

[0055] In this embodiment of the disclosure, the first guide member 21 may be a cylindrical structure, but is not limited thereto. The first guide member 21 may also be a structure of other shapes besides a cylindrical structure, depending on the actual situation.

[0056] like Figures 4 to 5 As shown, in some embodiments, a first limiting member 22 may be provided at the bottom of the first hopper 2, and the first limiting member 22 extends downward in a direction away from the first hopper 2. By providing the first limiting member 22, the present embodiment can, to a certain extent, improve the problem of tilting when the structural component 9 to be welded falls vertically. That is, the first limiting member 22 can guide the structural component 9 to be welded falling from the first discharge end to the second hopper 3, thereby ensuring that the structural component 9 to be welded can fall to the next station through the second discharge end after entering the second hopper 3.

[0057] For example, the side of the first limiting member 22 near the first vertical pusher 5 can be flush with the side of the first hopper 2 near the first vertical pusher 5, thereby reducing or avoiding the obstruction of the first limiting member 22 during the process of the unwelded structural member 9 falling into the second hopper 3.

[0058] In some embodiments, the second hopper 3 is located vertically below the first hopper 2 and is used to receive the structural component 9 to be welded that falls from the first discharge end. The second hopper 3 has a second discharge end. After the structural component 9 moves to the second discharge end, it can be moved to the next station by the push of the second vertical pusher 7. The second hopper 3 can move up and down in the vertical direction Z to realize loading and feeding.

[0059] Specifically, in this embodiment, the No. 2 hopper 3 can be raised to shorten the vertical distance between the No. 2 hopper 3 and the No. 1 hopper 2. When the No. 2 hopper 3 is raised to the preset feeding position, the No. 1 vertical pusher 5 pushes the structural component 9 to be welded on the first discharge end downward so that the structural component 9 to be welded falls into the No. 2 hopper 3, thereby realizing feeding.

[0060] like Figure 3 As shown, in some embodiments, multiple second guide members 31 arranged in an array at intervals can be provided in the second hopper 3. The second guide members 31 extend along the longitudinal direction Y, and their top surfaces abut against the structural member 9 to be welded.

[0061] For example, two second guide members 31 arranged in an array at intervals can be provided inside the second hopper 3. The length of the second guide members 31 in the longitudinal Y direction can be equal to the length of the second hopper 3 in the longitudinal Y direction. The bottom surface of the structural component 9 to be welded abuts against the top surface of the two second guide members 31. Compared with the scheme in which the structural component 9 to be welded is in complete contact with the bottom surface of the second hopper 3, the embodiment of this disclosure can reduce the friction surface when the structural component 9 to be welded moves in the second hopper 3, thereby reducing the friction force on the structural component 9 to be welded and the second hopper 3, thereby reducing the possibility of damage to the structural component 9 to be welded and the second hopper 3, and extending the service life of the structural component 9 to be welded and the second hopper 3. The two second guide members 31 can be symmetrically arranged about the central axis of the second hopper 3 in the longitudinal Y direction to form uniform and stable support for the structural component 9 to be welded.

[0062] In this embodiment of the present disclosure, the second guide member 31 may be a cylindrical structure, but is not limited thereto. The second guide member 31 may also be a structure of other shapes besides a cylindrical structure, depending on the actual situation.

[0063] like Figures 4 to 5 As shown, in some embodiments, a third limiting member 32 may be provided at the bottom of the second hopper 3, and the third limiting member 32 extends downward in a direction away from the second hopper 3. By providing the third limiting member 32, this embodiment of the present disclosure can, to a certain extent, improve the problem of tilting when the structural component 9 to be welded falls vertically. That is, the third limiting member 32 can guide the structural component 9 to be welded falling from the second discharge end to the next station, so as to improve the problem of positional deviation of the structural component 9 to be welded, thereby smoothly guiding the structural component 9 to be welded to the designated position in the next station.

[0064] For example, in this embodiment of the present disclosure, the side of the third limiting member 32 near the second vertical pusher 7 can be flush with the side of the second hopper 3 near the second vertical pusher 7, thereby reducing or avoiding the obstruction of the third limiting member 32 during the process of the unwelded structural member 9 falling into the second hopper 3.

[0065] In some embodiments, a first horizontal pusher 4 is located at the end of a first hopper 2 away from the first discharge end. The first horizontal pusher 4 can move back and forth within the first hopper 2 to push the structural component 9 to be welded in the first hopper 2 to the first discharge end.

[0066] like Figure 3As shown, in some embodiments, the first horizontal pushing member 4 can comprise a first pushing structure 41 capable of reciprocating in the longitudinal direction Y within the first bin 2 for pushing the to-be-welded structural member 9 in the first bin 2 to the first discharging end.

[0067] For example, the first pushing structure 41 in the embodiments of the present disclosure can move a distance within the first bin 2 equal to the length of the first bin 2 in the longitudinal direction Y. When pushing the to-be-welded structural member 9, the first pushing structure 41 enters the inside of the first bin 2 from a side wall of the first bin 2 away from the first discharging end to push the to-be-welded structural member 9 in the first bin 2 to the first discharging end.

[0068] In the embodiments of the present disclosure, when the first pushing structure 41 pushes the to-be-welded structural member 9, the contact surface between the first pushing structure 41 and the to-be-welded structural member 9 can completely cover the side of the to-be-welded structural member 9 away from the first discharging end, so as to reduce the contact stress between the first pushing structure 41 and the to-be-welded structural member 9, lower the risk of damage to the first pushing structure 41 and the to-be-welded structural member 9, and prolong the service life of the first pushing structure 41 and the to-be-welded structural member 9. However, the contact surface between the first pushing structure 41 and the to-be-welded structural member 9 can also be smaller than the side of the to-be-welded structural member 9 away from the first discharging end, which can be determined according to actual conditions.

[0069] In some embodiments, the first horizontal pushing member 4 can further comprise a first driving member 42 connected with the first pushing structure 41 for driving the first pushing structure 41 to move.

[0070] In the embodiments of the present disclosure, the first driving member 42 can be located outside the first bin 2 to reduce the occupied volume of the first bin 2, but is not limited thereto. The first driving member 42 can also be arranged inside the first bin 2, which can be determined according to actual conditions.

[0071] In some embodiments, the first vertical pushing member 5 is located vertically above the first discharging end for pushing the to-be-welded structural member 9 at the first discharging end to the second bin 3. When the to-be-welded structural member 9 is at the first discharging end, the first horizontal pushing member 4 and the first vertical pushing member 5 respectively abut against the opposite sides of the to-be-welded structural member 9 in the longitudinal direction Y.

[0072] For example, the first vertical pushing member 5 can comprise a second pushing structure 51 capable of reciprocating in the longitudinal direction Y within the second bin 3 for pushing the to-be-welded structural member 9 in the second bin 3 to the second discharging end. Figure 6As shown, in some embodiments, the first vertical pusher 5 may include a third pusher structure 51 and two first positioning members 52. The two first positioning members 52 may be symmetrically arranged on opposite sides of the first hopper 2 in the horizontal direction X. The first positioning member 52 has a first positioning surface facing the first hopper 2. When the structural member 9 to be welded is located at the first discharge end, the first positioning surface and the first horizontal pusher 4 respectively press against opposite sides of the structural member 9 to be welded in the longitudinal direction Y to clamp the structural member 9 to be welded. The third pusher structure 51 is located vertically above the first discharge end. The third pusher structure 51 can move up and down in the vertical direction Z to push the structural member 9 to be welded at the first discharge end to the second hopper 3.

[0073] For example, the first positioning element 52 in this embodiment of the present disclosure may be stepped.

[0074] Specifically, such as Figure 7 As shown, the first positioning member 52 may include a first layer structure 521, a second layer structure 522, and a third layer structure 523 located outside the first hopper 2, and the first layer structure 521, the second layer structure 522, and the third layer structure 523 are arranged sequentially along the longitudinal direction Y. The first layer structure 521 is located on opposite sides of the first hopper 2 in the transverse direction X, and one side of it in the longitudinal direction Y is flush with the side of the first hopper 2 close to the first vertical push member 5, while the other side extends in a direction away from the first vertical push member 5. The second layer structure 522 is connected to the side of the first layer structure 521 away from the first horizontal pusher 4. The side of the second layer structure 522 away from the central axis in the longitudinal Y direction of the first hopper 2 is flush with the side of the first layer structure 521 away from the central axis in the longitudinal Y direction of the first hopper 2. The side of the second layer structure 522 close to the central axis in the longitudinal Y direction of the first hopper 2 is flush with the inner surface of the adjacent side wall of the first hopper 2. The longitudinal Y length of the second layer structure 522 can be equal to the longitudinal Y length of the structural component 9 to be welded. The third layer structure 523 is connected to the side of the second layer structure 522 away from the first horizontal pusher 4. The side of the third layer structure 523 away from the central axis in the longitudinal Y direction of the first hopper 2 is flush with the side of the first layer structure 521 away from the central axis in the longitudinal Y direction of the first hopper 2. The transverse X length of the third layer structure 523 is greater than that of the second layer structure 522, and the side of the third layer structure 723 close to the first horizontal pusher 4 is spaced apart from the side of the first hopper 2 away from the first horizontal pusher 4. When the structural component 9 to be welded moves to the first discharge end, the opposite sides of the structural component 9 in the transverse X direction respectively abut against the side of the two second layer structures 522 near the central axis in the longitudinal Y direction of the first hopper 2, and the side of the structural component 9 to be welded away from the first horizontal pusher 4 abuts against the side of the third layer structure 523 near the first horizontal pusher 4, and the side of the structural component 9 to be welded near the first horizontal pusher 4 abuts against the first pusher structure 41. That is, the structural component 9 to be welded is fixed at the first discharge end by the first horizontal pusher 4 and the first positioning component 52.

[0075] The first positioning member 52 can be used to adjust the state of the to-be-welded structural member 9 at the first discharge end, so as to reduce or avoid the angle inclination of the to-be-welded structural member 9, thereby avoiding the problem that the to-be-welded structural member 9 cannot smoothly pass through the gap between the first bin 2 and the side of the third layer structure 523 close to the first horizontal pushing member 4 to enter the second bin 3.

[0076] It should be noted that when the first positioning member 52 is not arranged on the first vertical pushing member 5, the to-be-welded structural member 9 can also be inclined or deviated, and thus the to-be-welded structural member 9 can be stuck in the gap between the first bin 2 and the first vertical pushing member 5 when moving to the first discharge end, so that the to-be-welded structural member 9 cannot fall into the second bin 3. At this time, the first vertical pushing member 5 can be moved downward to adjust the position and angle of the to-be-welded structural member 9 on the first discharge end, so as to ensure that the to-be-welded structural member 9 can smoothly pass through the gap between the first bin 2 and the first vertical pushing member 5 to fall into the second bin 3.

[0077] In some embodiments, when the third pushing structure 51 is in the initial position, the bottom surface of the third pushing structure 51 in contact with the to-be-welded structural member 9 is higher than the top surface of the to-be-welded structural member 9 on the first discharge end. When the third pushing structure 51 moves downward, the bottom surface thereof abuts against the top surface of the to-be-welded structural member 9, and the to-be-welded structural member 9 gradually separates from the first positioning member 52 and the first horizontal pushing member 4 under the pushing of the third pushing structure 51, so that the to-be-welded structural member 9 can fall into the second bin 3 through the gap between the first bin 2 and the first vertical pushing member 5.

[0078] In the embodiments of the present disclosure, the shape and size of the bottom surface of the third pushing structure 51 can be matched with the shape and size of the top surface of the to-be-welded structural member 9, that is, the bottom surface of the third pushing structure 51 can completely fit the top surface of the to-be-welded structural member 9 when the third pushing structure 51 pushes the to-be-welded structural member 9, so as to reduce the contact stress and improve the stability of the pushing process.

[0079] As Figures 4 to 5As shown, in some embodiments, the first vertical pusher 5 may include a second limiting member 53, which is located below the third pusher structure 51 and extends along the vertical direction Z. In this embodiment, the top surface of the second limiting member 53 is not higher than the bottom surface of the first hopper 2, and the side of the second limiting member 53 near the first horizontal pusher 4 can be flush with the side of the third layer structure 523 near the first horizontal pusher 4. When the structural component 9 to be welded falls from the first discharge end, the second limiting member 53 can, to a certain extent, improve the problem of tilting when the structural component 9 falls vertically. That is, the second limiting member 53 can guide the structural component 9 to be welded falling from the first discharge end to the second hopper 3, thereby ensuring that the structural component 9 to be welded can fall to the next station through the second discharge end after entering the second hopper 3.

[0080] In some embodiments, the automatic welding device 1 may simultaneously include a first limiting member 22 and a second limiting member 53. The second limiting member 53 is spaced apart from the first limiting member 22, forming a first limiting space. When the structural component 9 to be welded is located on the first discharge end, both the structural component 9 to be welded and the first limiting space are located vertically above the second hopper 3, and the orthographic projection of the structural component 9 to be welded on the second hopper 3 is located within the orthographic projection of the first limiting space on the second hopper 3. Under the push of the third pushing structure 51, the structural component 9 to be welded on the first discharge end enters the second hopper 3 through the first limiting space.

[0081] In some embodiments, the second horizontal pusher 6 may be located at the end of the second hopper 3 away from the second discharge end. The second horizontal pusher 6 can move back and forth within the second hopper 3 to push the structural component 9 to be welded in the second hopper 3 to the second discharge end.

[0082] like Figure 6 As shown, in some embodiments, the second horizontal pusher 6 may include a second pusher structure 61, which is capable of reciprocating along the longitudinal Y direction within the second hopper 3 to push the structural component 9 to be welded in the second hopper 3 to the second discharge end.

[0083] For example, in this embodiment of the present disclosure, the movement distance of the second pushing structure 61 within the second hopper 3 can be equal to the length of the second hopper 3 in the longitudinal Y direction. When pushing the structural component 9 to be welded, the second pushing structure 61 enters the interior of the second hopper 3 from the side wall of the second hopper 3 away from the second discharge end, so as to push the structural component 9 to be welded in the second hopper 3 to the second discharge end.

[0084] In the embodiments of the present disclosure, when the second pushing structure 61 pushes the structure to be welded 9, the contact surface between the second pushing structure 61 and the structure to be welded 9 can completely cover the side of the structure to be welded 9 away from the second discharge end, so as to reduce the contact stress between the second pushing structure 61 and the structure to be welded 9, reduce the risk of damage of the second pushing structure 61 and the structure to be welded 9, and prolong the service life of the second pushing structure 61 and the structure to be welded 9. However, the contact surface between the second pushing structure 61 and the structure to be welded 9 can also be smaller than the side of the structure to be welded 9 away from the second discharge end, which can be determined according to actual conditions.

[0085] As shown in Figure 6 In some embodiments, the second horizontal pushing member 6 can further include a second driving member 62 connected with the second pushing structure 61 for driving the second pushing structure 61 to move.

[0086] In the embodiments of the present disclosure, the second driving member 62 can be located outside the second bin 3, so as to reduce the occupied volume of the second bin 3, but the present disclosure is not limited thereto, and the second driving member 62 can also be arranged in the second bin 3, which can be determined according to actual conditions.

[0087] In some embodiments, the second vertical pushing member 7 can be located vertically above the second discharge end, for pushing the structure to be welded 9 on the second discharge end out of the second bin 3 to the next station. When the structure to be welded 9 is located on the second discharge end, the second horizontal pushing member 6 and the second vertical pushing member 7 are respectively pressed on the opposite sides of the structure to be welded 9 in the longitudinal direction Y.

[0088] As shown in Figure 6 In some embodiments, the second vertical pushing member 7 can include a fourth pushing structure 71 and two second positioning members 72. The two second positioning members 72 can be symmetrically arranged on the opposite sides of the second bin 3 in the transverse direction X. The second positioning member 72 has a second positioning surface facing the second bin 3, and when the structure to be welded 9 is located on the second discharge end, the second positioning surface and the second horizontal pushing member 6 are respectively pressed on the opposite sides of the structure to be welded 9 in the longitudinal direction Y, so as to clamp the structure to be welded 9. The fourth pushing structure 71 is located vertically above the second discharge end, and the fourth pushing structure 71 can be lifted and lowered in the vertical direction Z, so as to push the structure to be welded 9 on the second discharge end out of the second bin 3 to the next station.

[0089] As shown in Figure 8 For example, the second positioning member 72 in the embodiments of the present disclosure can be in a stepped shape.

[0090] Specifically, the second positioning member 72 can include a first structure layer 721, a second structure layer 722 and a third structure layer 723 located outside the second material bin 3, and the first structure layer 721, the second structure layer 722 and the third structure layer 723 are arranged in sequence along the longitudinal direction Y. The first structure layer 721 is located on opposite sides of the second material bin 3 in the transverse direction X, and one side of the first structure layer 721 in the longitudinal direction Y is flush with a side of the second material bin 3 close to the second vertical pushing member 7, and the other side extends away from the second vertical pushing member 7. The second structure layer 722 is connected to the side of the first structure layer 721 away from the second horizontal pushing member 6, one side of the second structure layer 722 away from the central axis of the second material bin 3 in the longitudinal direction Y is flush with one side of the first structure layer 721 away from the central axis of the second material bin 3 in the longitudinal direction Y, and one side of the second structure layer 722 close to the central axis of the second material bin 3 in the longitudinal direction Y is flush with the inner surface of the side wall of the second material bin 3 adjacent thereto. The longitudinal length of the second structure layer 722 can be equal to the longitudinal length of the structure to be welded 9. The third structure layer 723 is connected to the side of the second structure layer 722 away from the second horizontal pushing member 6, one side of the third structure layer 723 away from the central axis of the second material bin 3 in the longitudinal direction Y is flush with one side of the first structure layer 721 away from the central axis of the second material bin 3 in the longitudinal direction Y, the transverse length of the third structure layer 723 is greater than that of the second structure layer 722, and one side of the third structure layer 723 close to the second horizontal pushing member 6 is arranged in a spaced manner from one side of the second material bin 3 away from the second horizontal pushing member 6. When the structure to be welded 9 moves to the second discharge end, the opposite sides of the structure to be welded 9 in the transverse direction X are respectively abutted against one side of the two second structure layers 722 close to the central axis of the second material bin 3 in the longitudinal direction Y, and one side of the structure to be welded 9 away from the second horizontal pushing member 6 is abutted against one side of the third structure layer 723 close to the second horizontal pushing member 6, and one side of the structure to be welded 9 close to the second horizontal pushing member 6 is abutted against the second pushing structure 61, that is, the structure to be welded 9 is fixed at the second discharge end by the second horizontal pushing member 6 and the second positioning member 72.

[0091] The second positioning member 72 can be used to adjust the state of the structure to be welded 9 at the second discharge end, reduce or avoid the angle inclination of the structure to be welded 9, so as to avoid the problem that the structure to be welded 9 cannot smoothly pass through the gap between the second material bin 3 and one side of the third structure layer 723 close to the second horizontal pushing member 6.

[0092] It should be noted that when the second vertical pusher 7 is not equipped with the second positioning part 72, the structural component 9 to be welded may become stuck in the gap between the second hopper 2 and the second vertical pusher 7 due to tilting or positional deviation when moving to the second discharge end, thus preventing it from falling to the next station. In this case, the position and angle of the structural component 9 to be welded on the second discharge end can be adjusted by moving the second vertical pusher 7 downward, thereby ensuring that the structural component 9 can smoothly pass through the gap between the second hopper 2 and the second vertical pusher 7 and fall to the next station.

[0093] In some embodiments, when the fourth pushing structure 71 is in its initial position, the bottom surface of the fourth pushing structure 71 that contacts the structural component 9 to be welded is higher than the top surface of the structural component 9 to be welded on the second discharge end. When the fourth pushing structure 71 moves downward, its bottom surface abuts against the top surface of the structural component 9 to be welded. Under the pushing of the fourth pushing structure 71, the structural component 9 to be welded gradually separates from the second horizontal pushing member 6 and the second positioning member 72, and then the structural component 9 to be welded can fall to the next station through the gap between the second hopper 3 and the second vertical pushing member 7.

[0094] In this embodiment of the present disclosure, the shape and size of the bottom surface of the fourth pushing structure 71 can be adapted to the shape and size of the top surface of the structural component 9 to be welded. That is, when the fourth pushing structure 71 pushes the structural component 9 to be welded, the bottom surface of the fourth pushing structure 71 can be completely attached to the top surface of the structural component 9 to be welded, thereby reducing contact stress and improving the stability of the pushing process.

[0095] like Figures 4 to 5 As shown, in some embodiments, the second vertical pusher 7 may include a fourth limiting member 73, which is located below the fourth pusher structure 71 and extends along the vertical direction Z. In this embodiment, the top surface of the fourth limiting member 73 is not higher than the bottom surface of the second hopper 3, and the side of the fourth limiting member 73 near the second horizontal pusher 6 may be flush with the side of the third layer structure 523 near the second horizontal pusher 6. When the structural component 9 to be welded falls from the second discharge end, the fourth limiting member 73 can, to a certain extent, improve the problem of tilting when the structural component 9 falls vertically. That is, the fourth limiting member 73 can guide the structural component 9 to be welded falling from the second discharge end to the next station, so as to improve the problem of positional deviation of the structural component 9, thereby smoothly guiding the structural component 9 to the designated position in the next station.

[0096] In some embodiments, the automatic welding device 1 can simultaneously include a third limiting member 32 and a fourth limiting member 73. The fourth limiting member 73 is spaced apart from the third limiting member 32 and forms a second limiting space. When the to-be-welded structural member 9 is located on the second discharge end, the to-be-welded structural member 9 and the second limiting space are both located vertically above the next work station, and the orthographic projection of the to-be-welded structural member 9 on the next work station is located within the orthographic projection of the second limiting space on the next work station. Under the pushing of the fourth pushing structure 71, the to-be-welded structural member 9 on the second discharge end enters the next work station through the second limiting space.

[0097] As shown in Figure 1 , Figure 2 , Figure 4 In some embodiments, the automatic welding device 1 can include a lifting mechanism 81 extending in the vertical direction Z, which can drive the second hopper 3 to lift.

[0098] Specifically, the automatic welding device 1 can include a bearing seat 82, one side surface of which is movably connected with the lifting mechanism 81. The top surface of the bearing seat 82 is placed with the second hopper 3, and the bearing seat 82 can drive the second hopper 3 to move up and down in the vertical direction Z under the driving of the lifting mechanism 81. In addition, the second horizontal pushing member 6 and / or the second vertical pushing member 7 can also be placed on the top surface of the bearing seat 82, so that the second horizontal pushing member 6 and / or the second vertical pushing member 7 can move up and down with the bearing seat 82.

[0099] As shown in Figure 6 In some embodiments, the bottom of the second hopper 3 can be provided with a support 83 extending downward in a direction away from the second hopper 3. During the movement of the to-be-welded structural member 9 from the second hopper 3 to the next work station, the bottom of the support 83 abuts against the next work station.

[0100] For example, the support 83 in the embodiments of the present disclosure can be arranged on the bottom surface of the bearing seat 82 and extend downward in a direction away from the bearing seat 82.

[0101] In some embodiments, the next station may include a welding component 84 located vertically below the second hopper 3, with the welding position forming an upward-facing welding groove. For example, the welding groove in this disclosure may be a U-shaped welding groove. After the structural component 9 to be welded falls into the second hopper 3, the second hopper 3 moves from the loading position to the feeding position; that is, after the structural component 9 to be welded falls into the second hopper 3, the second hopper 3 descends until the support member 83 abuts against the bottom wall of the inner sidewall of the welding groove. When the second hopper 3 moves to the feeding position, the structural component 9 to be welded moves to the second discharge end and falls to a designated position on the welding groove under the action of the second vertical pusher. It should be noted that the designated position here can refer to the welding position on the welding groove, where the structural component 9 can be welded.

[0102] It should be noted that a sensor can be installed on the second hopper 3 to sense the height of the second hopper 3, and then the lifting height of the second hopper 3 can be controlled based on the height information.

[0103] By setting a support member 83 at the bottom of the second hopper 3, this disclosure can reduce the impact force when the second hopper 3 comes into contact with the next work station, and at the same time, it can also create a certain height between the bottom of the second hopper 3 and the next work station, so as to ensure that the structural parts 9 to be welded on the second hopper 3 can be smoothly dropped to the next work station.

[0104] Specifically, in the event of a sensor failure on hopper 3, support component 83 can effectively ensure that when hopper 3 is in the feeding position, there is a certain height between the bottom of hopper 3 and the next work station, thereby ensuring that the structural component 9 to be welded on hopper 3 can be smoothly lowered to the next work station.

[0105] like Figure 6 As shown, in some embodiments, a buffer 85 can be provided on the side of the support member 83 facing away from the second hopper 3. The buffer 85 is elastic. In this embodiment, when the second hopper 3 is in the feeding position, the buffer 85 abuts against the next station. By providing the buffer 85, this disclosure can reduce the impact force when the second hopper 3 comes into contact with the next station, thereby reducing the risk of damage to the second hopper 3 and the next station.

[0106] In this embodiment, the automatic welding device 1 can be applied to the container manufacturing industry, wherein the structural component 9 to be welded can be a reinforcing member. Specifically, the structural component 9 to be welded can be a reinforcing member of a wide bottom beam, and the structural component 9 to be welded can remain upright throughout the entire loading and feeding machine welding process.

[0107] For example, the thickness of the structure 9 to be welded in the embodiment of the present disclosure can be 4 mm, at this time, the present disclosure can place 70 pieces of structure 9 to be welded in the first hopper 2 at a time, so that the present disclosure can realize continuous feeding of the structure 9 to be welded after single feeding of the first hopper 2. That is, after single feeding, the first horizontal pushing piece 4 can continuously push the structure 9 to be welded in the first hopper 2 to the first discharge end for 70 times to realize continuous feeding, so as to improve the influence of the feeding process of the structure 9 to be welded on the production efficiency and greatly improve the production efficiency.

[0108] The process flow of the automatic welding device 1 in the embodiment of the present disclosure can be: the structure 9 to be welded is placed in the first hopper 2 by manual feeding, and a plurality of structures 9 to be welded can be placed in the first hopper 2 at a time, at this time, the first horizontal pushing piece 4 is located on the side away from the first discharge end. The first horizontal pushing piece 4 moves to push the structure 9 to be welded in the first hopper 2 to the first discharge end. The structure 9 to be welded gradually contacts the first vertical pushing piece 5 in the process of moving from the first hopper 2 to the first discharge end, specifically, the structure 9 to be welded gradually contacts the two first positioning pieces 52 in the first vertical pushing piece 5 in the process of moving to the first discharge end, so that the structure 9 to be welded can be fixed at the first discharge end under the action of the first vertical pushing piece 5 and the first horizontal pushing piece 4. The first vertical pushing piece 5 moves downward to separate the structure 9 to be welded on the first discharge end from the first vertical pushing piece 5 and the first horizontal pushing piece 4, and then to make the structure 9 to be welded fall into the second hopper 3, at this time, the second horizontal pushing piece 6 is located on the side away from the second discharge end. The second horizontal pushing piece 6 moves to push the structure 9 to be welded in the second hopper 3 to the second discharge end and adjust the position of the structure 9 to be welded with the inclination angle to restore the vertical state. The structure 9 to be welded gradually contacts the second vertical pushing piece 7 in the process of moving from the second hopper 3 to the second discharge end, specifically, the structure 9 to be welded gradually contacts the two second positioning pieces 72 in the second vertical pushing piece 7 in the process of moving from the second hopper 3 to the second discharge end, so that the structure 9 to be welded can be fixed at the second discharge end under the action of the second vertical pushing piece 7 and the second horizontal pushing piece 6. The second vertical pushing piece 7 moves downward to separate the structure 9 to be welded on the second discharge end from the second vertical pushing piece 7 and the second horizontal pushing piece 6, and then to make the structure 9 to be welded fall into the next station.

[0109] It should be noted that after the second hopper 3 delivers the structure 9 to be welded to the next station, the second hopper 3, the first horizontal pushing piece 4, the first vertical pushing piece 5, the second horizontal pushing piece 6 and the second vertical pushing piece 7 can restore the initial position to circulate the feeding and feeding of the structure 9 to be welded.

[0110] Specifically, after the second hopper 3 delivers the to-be-welded structural member 9 to the next station, the fourth pushing structure 71 is raised so that the bottom surface thereof is higher than the top surface of the to-be-welded structural member 9 on the second discharge end. The second pushing structure 61 is moved to the end of the second hopper 3 away from the second discharge end. The second hopper 3 is raised from the feeding position to the feeding position. The third pushing structure 51 is raised so that the bottom surface thereof is higher than the top surface of the to-be-welded structural member 9 on the first discharge end. The first pushing structure 41 is moved to the end of the first hopper 2 away from the first discharge end. When the second hopper 3 is raised to the feeding position to realize feeding in the next time, the welding robot can be controlled to perform full welding on the to-be-welded structural member 9 at the next station. Since the second hopper 3 is spaced apart from the next station, the influence of the second hopper 3 on the welding process of the welding robot can be reduced or avoided.

[0111] It should be noted that, in some embodiments, the second pushing structure 61 returning to the initial position can also mean that the second pushing structure 61 is moved to any position between the end of the second hopper 3 away from the second discharge end and the second discharge end, and ensures that the second pushing structure 61 can push the to-be-welded structural member 9 in the second hopper 3 to the second discharge end.

[0112] In some embodiments, the first pushing structure 41 returning to the initial position can also mean that the first pushing structure 41 is moved to any position between the end of the first hopper 2 away from the first discharge end and the first discharge end, and ensures that the first pushing structure 41 can push the to-be-welded structural member 9 in the first hopper 2 to the first discharge end. Alternatively, when the first hopper 2 stores the to-be-welded structural member 9, after one to-be-welded structural member 9 falls into the second hopper 3, the first pushing structure 41 can continue to push the remaining to-be-welded structural member 9 in the first hopper 2 to the first discharge end, reducing the distance that the first pushing structure 41 needs to return to the end of the first hopper 2 away from the first discharge end and then push the to-be-welded structural member 9 to the first discharge end, so as to improve the feeding rate and reduce the driving energy consumption.

[0113] In addition, the next station in the present disclosure can be automatically replaced. Taking the welding member 84 as an example, the welding member 84 can form a welding groove extending along the longitudinal direction Y, and a plurality of rollers 86 can be arranged below the welding member 84. When the to-be-welded structural member 9 completes welding at one welding position in the welding groove, another welding position can be moved to the position directly below the second discharge end through the rollers 86, so as to facilitate the welding of the to-be-welded structural member 9 next time.

[0114] The embodiment of the present disclosure can realize the movement and positioning of the structure to be welded 9 by using the principle of the clip and through the mechanical transmission mechanism of the first horizontal pushing piece 4, the first vertical pushing piece 5, the second horizontal pushing piece 6, the second vertical pushing piece 7 and the like after the material is coded once, the whole process is simple and reliable, the installation precision of each structure to be welded 9 is ensured, and the problems such as the next station cannot be smoothly reached by the structure to be welded 9, or the structure to be welded 9 is misaligned with the next station, and then the installation is poor and scrapped due to the skew or inaccurate positioning of the structure to be welded 9 during the movement of the structure to be welded 9 are improved, and the welding quality and the yield of the product finally formed by the structure to be welded 9 are greatly improved.

[0115] Meanwhile, after the structure to be welded 9 is added to the first bin 2, the automatic welding device 1 can automatically realize the feeding and conveying of the structure to be welded 9. In addition, the automatic welding device 1 in the embodiment of the present disclosure can include a special machine or a welding robot cooperating with the next station to realize the automatic welding of the structure to be welded 9, and then the feeding, feeding and welding process of the structure to be welded 9 in the present disclosure can realize full automation, reduce the workload of personnel, greatly reduce the personnel cost, and improve the production efficiency.
