[0025] like Figures 1 to 4 As shown, the embodiment of the present invention provides an automated welding system, comprising:

[0026] A conveying mechanism, comprising a conveyor belt 101 and a driver 102, wherein the conveyor belt 101 is laid along a preset conveying route, and the driver 102 drives the conveyor belt 101 to rotate along the preset conveying route;

[0027] The loading mechanism includes a base 201, a rotating shaft 202, and a tray 203. The base 201 is disposed on the conveyor belt 101. The conveyor belt 101 drives the loading mechanism to rotate along the preset conveying route through the base 201. The tray 203 is rotatably connected to the base 201 via the rotating shaft 202.

[0028] The welding mechanism includes a platform 301, a robotic arm 302 and a welding head 303. The platform 301 is arranged at intervals beside the conveyor belt 101, and the height of the platform 301 is adapted to the height of the conveyor belt 101. The robotic arm 302 includes a fixing portion 3021, a first connecting member 3022, a first section arm 3023, a second connecting member 3024, a second section arm 3025 and an adjusting portion 3026. The fixing portion 3021 is arranged on the platform 301. The fixing portion 3021 is arranged on the platform 301. The first connecting member 3022 is rotatably connected to one end of the first arm 3023, the other end of the first arm 3023 is rotatably connected to one end of the second arm 3025 through the second connecting member 3024, and the other end of the second arm 3025 is connected to the welding head 303 through the adjusting portion 3026, wherein the rotation axis of the first connecting member 3022 is perpendicular to the plane where the conveyor belt 101 is located, and the rotation axis of the second connecting member 3024 is parallel to the rotation axis of the first connecting member 3022.

[0029] Among them, the automated welding system can be deployed in a welding workshop. Depending on the actual situation of the site, the preset conveying route can be a straight line or a curve. The conveying mechanism can include multiple bracket units. By splicing and combining the multiple bracket units, the laying route of the conveying mechanism can be conveniently adjusted so that the conveyor belt 101 set on the multiple bracket units is laid along the preset conveying route. The driver 102 can use a motor of appropriate power to provide stable power to the conveyor belt 101 through belt drive, chain drive or gear drive, etc., to ensure that the conveyor belt 101 can continue to run stably according to the predetermined trajectory, thereby realizing reliable transportation of the workpiece. In this way, under the driving action of the driver 102, the conveyor belt 101 can perform rotational motion on the preset conveying route.

[0030] Among them, the loading mechanism includes a base 201, a rotating shaft 202 and a tray 203. The tray 203 is used to place the workpiece to be welded. The base 201 is fixed on the conveyor belt 101. When the conveyor belt 101 rotates, the base 201 drives the entire loading mechanism to move along the preset conveying line to transport the workpiece to be welded to the welding mechanism position, so as to facilitate the subsequent welding operation on the workpiece to be welded. The tray 203 is rotatably connected to the base 201 through the rotating shaft 202, so that the workpiece to be welded placed on the tray 203 can be flexibly rotated around the rotating shaft 202. Before welding, the workpiece to be welded can be adjusted to the optimal welding angle. During the welding process, the welding angle of the workpiece to be welded can also be flexibly adjusted to reduce the situation of false welding and leaking welding.

[0031] The welding mechanism includes a platform 301, a robotic arm 302, and a welding head 303. The platform 301 is spaced apart to the side of the conveyor belt 101. The height of the platform 301 is adapted to the height of the conveyor belt 101 to ensure smooth welding operations. For example, the platform 301 can have a double-layer structure, including an upper loading platform and a lower loading platform. The upper and lower loading platforms can be connected in a nested manner. This allows for flexible adjustment of the height of the platform 301 to match the height of the conveyor belt 101, facilitating subsequent welding operations.

[0032] The robotic arm 302 includes a fixed portion 3021, a first connecting member 3022, a first segment arm 3023, a second connecting member 3024, a second segment arm 3025, and an adjustment portion 3026. The fixed portion 3021 is fixed to the carrier 301, providing stable support for the robotic arm. The fixed portion 3021 is rotatably connected to one end of the first segment arm 3023 via the first connecting member 3022, and the rotation axis of the first connecting member 3022 is perpendicular to the plane of the conveyor belt 101, allowing the first segment arm 3023 to rotate within a plane perpendicular to the conveyor belt 101. The other end of the first segment arm 3023 is rotatably connected to one end of the second segment arm 3025 via the second connecting member 3024, and the rotation axis of the second connecting member 3024 is parallel to the rotation axis of the first connecting member 3022. Thus, the second arm 3025 can move in the same rotational direction as the first arm 3023. Through the coordinated rotation of the first connecting member 3022 and the second connecting member 3024, the robot arm 302 can telescopically move in a plane parallel to the conveyor belt 101 to adjust the distance between the welding head 303 at the end of the robot arm 302 and the pallet 203. Compared with the universal joint in the related art, the first connecting member 3022 and the second connecting member 3024 have greater stability and improve welding accuracy.

[0033] In addition, the other end of the second arm 3025 is connected to the welding head 303 through the adjustment part 3026. The adjustment part 3026 can realize fine adjustment of the welding head 303 in terms of angle, position, etc., so that the welding head 303 can accurately reach the welding part of the workpiece and complete high-quality welding operations.

[0034] In the embodiment of the present invention, the workpiece to be welded is first placed on the tray 203 of the loading mechanism, the driver 102 is started, and the conveyor belt 101 is driven to rotate, so that the loading mechanism loaded with the workpiece moves along the preset conveying route; when the workpiece moves to the corresponding position of the welding mechanism, the mechanical arm 302 of the welding mechanism accurately adjusts the position and angle of the welding head 303 through the coordinated rotation of the fixing portion 3021, the first connecting member 3022, the first segment arm 3023, the second connecting member 3024 and the second segment arm 3025, and with the assistance of the adjustment portion 3026, so that the welding head 303 is aligned with the welding point of the workpiece, and then the workpiece is welded by the welding head 303. In addition, the workpiece on the tray 203 can be driven to rotate by the rotating shaft 202, and the angle between the workpiece and the welding head 303 can be further fine-tuned to reduce the situation of false welding and leaking welding, thereby improving the welding accuracy. The rotatable design of the loading mechanism's tray 203 and the multi-degree-of-freedom precision motion of the welding mechanism's robotic arm 302 ensure accurate alignment of the welding head 303 with the workpiece's welding location, effectively controlling the welding angle and position, thereby improving welding quality and reducing welding defects. After welding is completed, the conveyor belt 101 continues to move the loading mechanism and the welded workpiece out of the welding area for the next welding cycle. This reduces manual intervention time, enables continuous automated welding of workpieces, and improves welding production efficiency.

[0035] Optionally, the adjusting part 3026 includes a first base, a guide rail and a second base, the second base is slidingly connected to the first base through the guide rail, the first base is arranged at the end of the second section arm 3025, the second base is connected to the welding head 303, and the extension direction of the guide rail is perpendicular to the plane where the conveyor belt 101 is located.

[0036] In this embodiment, the workpiece to be welded is first placed on the tray 203 of the loading mechanism, and the driver 102 is started, driving the conveyor belt 101 to rotate, so that the loading mechanism loaded with the workpiece moves along the preset conveying route; when the workpiece moves to the corresponding position of the welding mechanism, the first connecting member 3022 and the second connecting member 3024 rotate in conjunction, so that the robot arm 302 can perform telescopic movement in a plane parallel to the conveyor belt 101 to adjust the horizontal distance between the welding head 303 at the end of the robot arm 302 and the workpiece on the tray 203; further, for workpieces of different heights, or different heights of the welding points on the same workpiece, the second base can drive the welding head 303 to slide on the guide rail to adjust the vertical distance between the welding head 303 and the workpiece on the tray 203, so that the welding head 303 is aligned with the workpieces of different heights, or different heights of the welding points on the workpiece. In addition, the workpiece on the tray 203 can be rotated by the rotating shaft 202 to further fine-tune the angle between the workpiece and the welding head 303. The welding head 303 can be adjusted more flexibly and precisely in position and angle in three dimensions, thereby accurately reaching the welding location of the workpiece and completing high-quality welding operations. This reduces manual intervention time, enables continuous automated welding of workpieces, and improves welding production efficiency.

[0037] Optionally, the second base is rotatably connected to the welding head 303 .

[0038] In this example, the first connector 3022 and the second connector 3024 rotate in coordination, allowing the robotic arm 302 to perform telescopic movement in a plane parallel to the conveyor belt 101 to adjust the horizontal distance between the welding head 303 at the end of the robotic arm 302 and the workpiece on the pallet 203. For example, the first connector 3022 and the second connector 3024 rotate in coordination, causing the angle between the first section arm 3023 and the second section arm 3025 to decrease (i.e., the robotic arm 302 bends), thereby increasing the horizontal distance between the welding head 303 at the end of the robotic arm 302 and the workpiece on the pallet 203, thereby reducing interference during the movement of the workpiece. For another example, the first connector 3022 and the second connector 3024 rotate in coordination, causing the angle between the first section arm 3023 and the second section arm 3025 to increase (i.e., the robotic arm 302 straightens), thereby decreasing the horizontal distance between the welding head 303 at the end of the robotic arm 302 and the workpiece on the pallet 203, thereby facilitating the welding head 303 to perform welding operations on the workpiece.

[0039] In addition, the welding head 303 can not only perform precise linear sliding adjustment (i.e., adjust the vertical distance between the welding head 303 and the workpiece) relative to the second arm 3025 in a direction perpendicular to the plane of the conveyor belt 101, but can also rotate around the connection point with the second base. Through the combination of the rotation of the first arm 3023 and the second arm 3025 and the sliding and rotational adjustment of the adjustment part 3026, the welding head 303 can be more flexible and precise in position and angle adjustment in three-dimensional space, so that the welding part of the workpiece can be accurately reached and high-quality welding operations can be completed. In this way, the design of the adjustment part 3026 makes the positioning of the welding head 303 faster and more accurate, further shortens the preparation time for welding a single workpiece, and thus improves the overall production efficiency. The second base is rotatably connected to the welding head 303, which can complete the angle fine-tuning of the welding head 303 more quickly, reducing the overall welding time.

[0040] Optionally, the system further includes a control mechanism, which is electrically connected to the conveying mechanism, the loading mechanism and the welding mechanism respectively, and the welding mechanism further includes a sensor, which is arranged toward the conveyor belt 101; when the sensor detects that the loading mechanism moves to the working area of ​​the welding mechanism through the conveying mechanism, the control mechanism controls the driver 102 to stop driving the conveyor belt 101 to rotate, and controls the robotic arm 302 to drive the welding head 303 to move toward the pallet 203; after the welding head 303 completes partial welding of the workpiece on the pallet 203, the control mechanism controls the rotation of the rotating shaft 202, and controls the welding head 303 to complete welding of the remaining parts of the workpiece; after completing all welding work on the workpiece, the control mechanism controls the driver 102 to drive the conveyor belt 101 to continue rotating.

[0041] In this embodiment, after the workpiece to be welded is placed on the tray 203 of the loading mechanism, the control mechanism controls the driver 102 to drive the conveyor belt 101 to rotate, so as to drive the loading mechanism loaded with the workpiece to be welded to move along the preset conveying route; when the sensor on the welding mechanism detects that the loading mechanism moves to the working area of ​​the welding mechanism through the conveyor belt 101 of the conveying mechanism, the control mechanism controls the driver 102 to stop driving the conveyor belt 101 to rotate, and controls the first connecting member 3022 and the second connecting member 3024 of the robot arm 302 to rotate in coordination, so that the robot arm 302 can extend in a plane parallel to the conveyor belt 101. The robot arm 302 can be used to move the welding head 303 toward the pallet 203, thereby adjusting the horizontal distance between the welding head 303 at the end of the robot arm 302 and the workpiece on the pallet 203. For workpieces of different heights, or welding points of different heights on the same workpiece, the control mechanism can also be used to control the second base to drive the welding head 303 to slide on the guide rail to adjust the vertical distance between the welding head 303 and the workpiece on the pallet 203. In this way, by controlling the robot arm 302 to drive the welding head 303 to move toward the pallet 203, the position and angle of the welding head 303 can be accurately adjusted so that the welding head 303 is aligned with the welding point of the workpiece, thereby improving the accuracy of the welding head 303 when performing welding operations on the workpiece.

[0042] In one example, while controlling the robotic arm 302 to drive the welding head 303 toward the pallet 203, the control mechanism can also be used to control the rotating shaft 202 to drive the workpiece on the pallet 203 to rotate, further fine-tune the angle between the workpiece and the welding head 303, reduce the situation of false welding and leaking welding, and improve the welding accuracy. In this way, the rotatable design of the pallet 203 in the loading mechanism and the multi-degree-of-freedom precise movement of the welding mechanism robotic arm 302 can ensure the accurate docking of the welding head 303 with the welding part of the workpiece, effectively control the welding angle and position, thereby improving the welding quality and reducing welding defects. After the welding is completed, the conveyor belt 101 is controlled to continue to drive the loading mechanism and the welded workpiece to leave the welding area and proceed to the next welding cycle, reducing the time of manual intervention, realizing continuous automatic welding of the workpiece, and improving welding production efficiency.

[0043] In another example, after the welding head 303 completes welding a portion of the workpiece on the tray 203, the control mechanism controls the rotation of the rotating shaft 202 to adjust the position of the workpiece. Thus, by controlling the rotation of the tray 203, the angle and position of the workpiece relative to the welding head 303 can be changed, allowing the welding head 303 to continue welding other unwelded areas of the workpiece without the need for manual readjustment of the workpiece position, thereby improving the continuity and efficiency of welding. After controlling the welding head 303 to complete welding the remaining portion of the workpiece, the control mechanism controls the driver 102 to drive the conveyor belt 101 to continue rotating and proceed to the next welding cycle, thereby reducing manual intervention time and achieving continuous automated welding of workpieces.

[0044] Optionally, the system further includes a picking mechanism and a receiving mechanism, the picking mechanism and the receiving mechanism are both arranged at intervals on the side of the conveyor belt 101, and the picking mechanism is close to the starting end of the conveyor belt 101 for rotational movement, and the receiving mechanism is close to the return end of the conveyor belt 101 for rotational movement, and the welding mechanism is located between the picking mechanism and the receiving mechanism, the picking mechanism is used to transfer the workpiece to be welded from the first storage area to the pallet, and the receiving mechanism is used to transfer the welded workpiece from the pallet to the second storage area.

[0045] In this embodiment, a retrieval mechanism is used to transfer workpieces to be welded from the first storage area to the pallet 203. The retrieval mechanism may include a mechanical gripper, a lifting device, and a lateral movement device. The mechanical gripper can adaptively grasp the workpiece according to its shape and size, adjust its height using the lifting device, and accurately contact the workpiece in the first storage area. The lateral movement device then moves the grasped workpiece to the pallet 203 on the conveyor belt 101 and places the workpiece on the pallet 203, thus achieving automated retrieval and improving work efficiency. The receiving mechanism is used to transfer the welded workpiece from the pallet 203 to the second storage area. The receiving mechanism may also include a mechanical gripper, a lifting device, and a lateral movement device. After welding is completed, when the pallet 203 loaded with the welded workpiece moves along the conveyor belt 101 to the vicinity of the receiving mechanism, the mechanical gripper of the receiving mechanism, in conjunction with the lifting device and lateral movement device, grasps the workpiece from the pallet 203 and transfers it to the second storage area, completing the storage of the welded workpiece and further improving the automation level of the system.

[0046] Specifically, during actual use of this automated welding system, the workpiece retrieval mechanism begins operation. The retrieval mechanism's mechanical gripper, working in concert with the lifting and lateral movement mechanisms, grabs the workpiece to be welded from the first storage area and transfers it to the pallet 203 near the starting end of the conveyor belt 101. The driver 102 is activated, driving the conveyor belt 101 in rotation, causing the loading mechanism, loaded with the workpiece, to move along a pre-set conveyor path. When the workpiece reaches the corresponding position of the welding mechanism, the pallet 203 is rotated via the rotating shaft 202, adjusting the workpiece angle so that the welding head 303 can accurately align with the desired welded portion of the workpiece. The welding mechanism's mechanical arm 302, through the coordinated rotation of the fixed portion 3021, first connecting member 3022, first segment arm 3023, second connecting member 3024, and second segment arm 3025, and the sliding and rotational adjustment of the adjustment portion 3026, precisely positions the welding head 303 at the welding location on the workpiece. The welding head 303 is then activated to begin welding. After the welding head 303 completes a portion of the welding on the workpiece on the pallet 203, the control mechanism controls the rotation of the rotating shaft 202 again based on the preset welding program or real-time monitoring of the welding progress. By rotating the pallet 203, the angle and position of the workpiece relative to the welding head 303 are changed, allowing the welding head 303 to continue welding other unwelded areas of the workpiece. This eliminates the need for manual readjustment of the workpiece position, improving welding continuity and efficiency. After welding is completed, the conveyor belt 101 continues to move the loading mechanism and the welded workpiece toward the receiving mechanism. When the workpiece reaches the receiving mechanism, the receiving mechanism's mechanical gripper, working in conjunction with the lifting and lateral movement mechanisms, grabs the welded workpiece from the pallet 203 and transfers it to the second storage area, completing the welding process. The system then continues with the next welding cycle. The addition of the retrieval and receiving mechanisms further streamlines the overall welding process. The retrieval mechanism automates the transfer of workpieces from the first storage area to the pallet, while the receiving mechanism automates the transfer of welded workpieces to the second storage area. These processes eliminate the need for manual workpiece handling, significantly reducing overall processing time.

[0047] Optionally, a plurality of loading mechanisms are provided on the conveyor belt 101 , and the spacing distances between adjacent loading mechanisms among the plurality of loading mechanisms are the same.

[0048] In this embodiment, the conveyor belt 101 is equipped with multiple loading mechanisms, with adjacent loading mechanisms spaced at equal distances from each other. This uniform spacing ensures a more regular distribution of workpieces throughout the conveying and welding process, facilitating orderly system operation and management. As the conveyor belt 101 rotates, the loading mechanisms move synchronously with it. Each loading mechanism can independently carry the workpieces to be welded, and its base 201 is tightly connected to the conveyor belt 101, ensuring stability during the conveying process. The fixed spacing between adjacent loading mechanisms facilitates accurate alignment of the workpieces when placing them, allowing the loading mechanism to sequentially place the workpieces onto the trays 203 of each loading mechanism according to a predetermined pattern. Furthermore, during the welding process, it facilitates the welding mechanism to accurately weld the workpieces on each loading mechanism according to the specified spacing and welding sequence, preventing problems such as misaligned or missed weld positions. Furthermore, after welding is completed, the receiving mechanism can systematically transfer the welded workpieces from the trays 203 of each loading mechanism to the second storage area, following this fixed spacing. It reduces manual intervention time, realizes continuous automatic welding of workpieces, and greatly improves welding production efficiency.

[0049] Optionally, a plurality of the welding mechanisms are provided beside the conveyor belt 101 , and the spacing distance between adjacent welding mechanisms among the plurality of the welding mechanisms is the same as the spacing distance between adjacent loading mechanisms among the plurality of the loading mechanisms.

[0050] In this embodiment, multiple loading mechanisms are installed on the conveyor belt 101, with adjacent loading mechanisms spaced at equal distances. Furthermore, multiple welding mechanisms are installed alongside the conveyor belt 101, with the spacing between adjacent welding mechanisms being equal to the spacing between adjacent loading mechanisms. This allows for the regular welding of workpieces at different locations while the conveyor belt 101 transports the loading mechanisms and workpieces, ensuring efficient and orderly welding operations. This, combined with the layout of the loading mechanisms, further optimizes the overall welding system workflow, thereby improving overall system coordination and efficiency.

[0051] Optionally, an anti-slip pad is provided on the tray 203 .

[0052] The anti-slip pad effectively increases the friction between the workpiece and pallet 203. This ensures the workpiece remains stable on pallet 203 during the movement of the loading mechanism by conveyor belt 101 and the rotation of pallet 203, preventing the workpiece from shifting due to shaking or sliding, which could affect the accuracy and quality of welding. Furthermore, the anti-slip pad also protects the workpiece surface to a certain extent, preventing scratches and other damage caused by direct contact and friction with pallet 203, thus meeting the processing requirements of workpieces requiring high precision.

[0053] Optionally, a limiting structure is provided on the tray 203 , and the area formed around the limiting structure is adapted to the shape of the workpiece to be welded.

[0054] A limiting structure can also be provided on the tray 203, and the area formed around the limiting structure is adapted to the shape of the workpiece to be welded. This limiting structure can be composed of components such as a raised frame and a positioning block. When the workpiece is placed on the tray 203, the limiting structure can accurately limit the placement position of the workpiece so that it is consistent with the initial position required for welding, further ensuring that the welding head 303 can accurately align with the corresponding part of the workpiece during the welding operation. Moreover, during the transportation of the conveyor belt 101 and the rotation of the tray 203, the limiting structure can also effectively prevent the workpiece from undergoing large displacement or rotation due to external forces, ensuring that the workpiece is always in a suitable welding position, thereby improving the accuracy and stability of welding.

[0055] Optionally, the joint type of the welding joint 303 is any one of a butt joint, a T-joint, a corner joint and a lap joint.

[0056] The joint type of the welding head 303 is any one of a butt joint, a T-joint, a corner joint and a lap joint. Different joint types are suitable for different workpiece connection requirements. Butt joints are often used to connect two oppositely placed workpieces along the same plane, which can provide better connection strength and sealing; T-joints are suitable for connecting one workpiece vertically to another workpiece to form a "T"-shaped structure, which is more common in the welding of some frame structures; corner joints are mainly used to connect the edges of two workpieces that are perpendicular to each other to ensure the strength and stability of the connection; lap joints are to place one workpiece partially overlapped on another workpiece for welding, which is relatively simple to operate and is often used for some thin plates or occasions where high-strength connections are not required.
