Description

Technical Field

[0001] This utility model relates to the field of welding processing technology, and more specifically, to a robotic automated welding device. Background Technology

[0002] In modern industrial manufacturing, several stiffening plates are typically welded inside the steel channel to increase its strength and stability. This process is widely used in bridges, building structures, heavy machinery frames, and shipbuilding. Traditional welding methods require manual positioning and support of each stiffening plate to ensure accurate placement during welding and prevent quality problems caused by misalignment or movement.

[0003] However, existing technologies have significant limitations. First, when welding stiffening plates at different locations, the precise positioning of each stiffening plate within the steel channel becomes extremely inconvenient due to its varying welding position. Workers need to spend a considerable amount of time adjusting and fixing the stiffening plate's position, which not only reduces work efficiency but also increases the workers' workload. Second, manual positioning and support methods cannot guarantee the consistency and accuracy of each weld, easily leading to fluctuations in product quality. Furthermore, the high temperatures and intense light generated during welding can also negatively impact the health of the operators. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a robotic automated welding device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A robotic automated welding device includes a conveyor for conveying a steel trough to be welded. A support frame is installed on one side of the conveyor, and a welding robot is installed on the other side. A positioning seat is connected to the top of the support frame, and a transmission column is slidably installed inside the positioning seat. A positioning and feeding mechanism is provided on the surface of the transmission column.

[0007] Furthermore, in order to place multiple ribs that need to be welded inside the transmission column, the positioning and feeding mechanism includes a storage trough inside the transmission column, a push rod suspended on one side of the support frame, the end of the push rod cooperating with the storage trough, and a discharge port at the bottom of the storage trough.

[0008] Furthermore, in order to achieve automatic feeding and positioning of the reinforcing plates in the steel channel during welding, a limit groove is opened on one side of the transmission column, and an adjustment plate is slidably installed inside the limit groove. The bottom of the adjustment plate and the discharge port are both connected to the limit plate. An electric push rod is installed on one side of the transmission column, and a push plate is installed at one end of the electric push rod in the storage tank.

[0009] Furthermore, in order to clamp and limit the adjustment plate after adjustment, clamping bolts are threaded on both sides of the bottom of the limiting groove.

[0010] Furthermore, in order to achieve the lifting and lowering adjustment of the transmission column, a lifting frame is installed on one side of the transmission column surface, and electric push rods are installed on both sides of the support frame surface. The ends of the electric push rods are connected to the bottom of the lifting frame.

[0011] Furthermore, in order to adjust the welding position of the welding robot, an adjustment plate is connected to one side of the bottom of the conveyor. The surface of the adjustment plate has a sliding groove, and a transmission screw is rotatably installed inside the sliding groove. The transmission screw is threadedly connected to the bottom of the welding robot.

[0012] Furthermore, in order to control the various electrical components within the device, a drive motor is connected to one end of the drive screw, and a multi-control switch is installed on one side of the support frame.

[0013] The beneficial effects of this utility model are as follows: the conveyor can automatically transport the steel troughs to be welded, and accurately adjust the different welding positions inside the steel troughs after they are moved. The positioning and feeding mechanism can automatically feed the stiffening plates to be welded in the steel troughs and stably support them after feeding, so as to achieve automatic positioning of the stiffening plates during welding. There is no need for manual positioning and support. After positioning, the welding robot can automatically weld them, realizing the full automation of the welding process. Compared with the traditional method of manually positioning and supporting each welder, it significantly improves production efficiency and welding accuracy, greatly shortens the processing cycle of a single product, reduces the labor intensity of workers, and effectively protects the occupational health and safety of workers.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] According to an embodiment of the present invention, a robotic automated welding device is provided.

[0024] like Figure 1 and Figure 2 As shown, an automated robotic welding device according to an embodiment of the present invention includes a conveyor 1 for transporting a steel trough 7 to be welded. The conveyor 1 is a belt conveyor 1, which is driven by a servo motor to rotate the conveyor belt and realize automated material transportation. A support frame 2 is installed on one side of the conveyor 1, and a welding robot 3 is installed on the other side. The robot can be programmed through a teach pendant to determine the welding path, and the robotic arm drives the welding torch to perform automated welding along the set path. A positioning seat 4 is connected to the top of the support frame 2. A transmission column 5 is slidably installed inside the positioning seat 4. A positioning and feeding mechanism 6 is provided on the surface of the transmission column 5 to realize the automatic feeding and positioning of the stiffeners during the welding of the steel trough 7. The conveyor 1 can drive the steel trough 7 to move precisely, thereby accurately adjusting the different welding positions inside the steel trough 7.

[0025] like Figures 2-5As shown, the positioning and feeding mechanism 6 includes a storage trough 601 inside the transmission column 5, used to store multiple stiffening plates in the storage trough 601 before welding, facilitating subsequent automated feeding; a push rod 602 is suspended on one side of the support frame 2, the end of the push rod 602 cooperating with the storage trough 601, and a discharge port 603 is opened at the bottom of the storage trough 601. After multiple stiffening plates are placed in the storage trough 601, the push rod 602 is inserted into the storage trough 601 to push the stiffening plates inside, moving them to the discharge port 603 side; a limit groove 604 is opened on one side of the transmission column 5, and an adjusting plate 605 is slidably installed inside the limit groove 604. By adjusting the installation position of the adjusting plate 605 in the limit groove 604, the size of the discharge port 603 can be changed, so that the width of the discharge port 603 matches the thickness of the stiffening plate, thereby allowing only one stiffening plate to fall into the storage trough 601 at a time; the adjusting plate Both 605 and the bottom of the discharge port 603 are connected to limit plates 606, which are used to limit the ribs after they fall, preventing them from shifting during welding. An electric push rod 607 is installed on one side of the transmission column 5. One end of the electric push rod 607 is fitted with a pusher plate 608 in the storage tank 601. The electric push rod 607 drives the pusher plate 608 to move within the storage tank 601, allowing the pusher plate 608 to push each rib. The plate moves towards the discharge port 603. When the outermost rib moves to be directly above the discharge port 603 and mates with it, the rib can fall from the discharge port 603 into the steel channel 7, realizing the automatic feeding of the rib to be welded in the steel channel 7. The bottom sides of the limiting groove 604 are threaded with clamping bolts 609, which are used to adjust the plate 605 after it slides and adjusts in the limiting groove 604. By turning the clamping bolts 609, the adjusted plate 605 is clamped and limited.

[0026] like Figure 3 and Figure 4As shown, a lifting frame 8 is installed on one side of the surface of the transmission column 5, and electric push rods 9 are installed on both sides of the surface of the support frame 2. The ends of the electric push rods 9 are connected to the bottom of the lifting frame 8. By adjusting the extension and retraction of the electric push rods 9, the lifting frame 8 can drive the transmission column 5 to move up and down. After the welding of a single stiffener plate is completed, the lifting frame 8 moves upward, thereby preventing the limiting plate 606 from limiting the stiffener plate, which facilitates the movement of the conveyor 1, the steel trough 7, and the welded stiffener plate. A bearing plate 10 is connected to one side of the bottom of the conveyor 1. The surface of the support frame 10 has a sliding groove 11, and a transmission screw 12 is rotatably installed inside the sliding groove 11. The transmission screw 12 is threadedly connected to the bottom of the welding robot 3 and is slidably installed in the sliding groove 11. One end of the transmission screw 12 is connected to a transmission motor 13. The transmission motor 13 drives the transmission screw 12 to rotate, so that the transmission screw 12 drives the welding robot 3 to move along the support plate 10, thereby realizing the adjustment of the welding position of the welding robot 3. A multi-control switch 14 is installed on one side of the surface of the support frame 2 for controlling the various electrical components in the device.

[0027] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0028] In actual use, the steel trough 7 to be welded is placed on the conveyor belt of the conveyor 1. The conveyor belt is driven by a servo motor to adjust the position of the steel trough 7 on the surface of the conveyor 1. Before loading, the operator vertically places multiple reinforcing plates to be welded into the storage trough 601 in the transmission column 5, and pushes them to the side of the discharge port 603 by the push rod 602. The width of the discharge port 603 can be precisely adjusted by adjusting the position of the adjusting plate 605 in the limiting groove 604. The clamping bolts 609 on both sides of the limiting groove 604 are tightened. The adjusting plate 605 can be fixed in a suitable position so that the width of the discharge port 603 is slightly larger than the thickness of a single rib, thus ensuring that only one rib can pass through at a time, achieving single-piece separate feeding. When material needs to be added to the steel trough 7, the electric push rod 607 is activated, pushing the pusher plate 608 connected to its end forward in the storage trough 601, pushing the foremost rib to directly above the discharge port 603. Since there is no support below the discharge port 603, the rib automatically falls under gravity and accurately lands in the predetermined welding position of the steel trough 7 below. After the rib falls, its two sides are limited by the limiting plates 606 fixed to the bottom of the discharge port 603 and the adjusting plate 605 to prevent it from shifting or tilting during welding, ensuring assembly accuracy. After the rib is positioned, the welding robot 3 begins to work. The robot can be pre-programmed with a teach pendant to set the weld path, and the robotic arm drives the welding torch to automatically weld the connection between the rib and the steel trough 7 according to the preset trajectory.
