[0042] In the existing technology, the feeding position of the gooseneck trough is on the side where the welding worker operates. When feeding, the worker needs to avoid the feeding position, which not only affects production efficiency but also poses a safety hazard.

[0043] To address the aforementioned technical problems, this application provides a conveyor frame, comprising: a material preparation assembly for placing materials to be processed; a welding conveyor table arranged side-by-side with the material preparation assembly for conveying the materials to a first welding assembly; and a material handling assembly that spans and connects the material preparation assembly and the welding conveyor table; the material handling assembly is configured to pick up materials from the material preparation assembly and transport them to the welding conveyor table. This will be described in detail below.

[0044] refer to Figure 1 A conveyor frame includes: a material preparation assembly 100 for placing material a to be processed; a welding conveyor 200 arranged side-by-side with the material preparation assembly 100 for conveying material a to a first welding assembly 400; and a material handling assembly 300 spanning and connecting the material preparation assembly 100 and the welding conveyor 200; the material handling assembly 300 is configured to grab material a from the material preparation assembly and transport it to the welding conveyor 200.

[0045] In this embodiment, the material preparation component 100 and the welding conveyor 200 are arranged side by side. Both the material preparation component 100 and the welding conveyor 200 are located below the material handling component 300. The material handling component 300 spans and connects the material preparation component 100 and the welding conveyor 200. The material handling component 300 transports the material a located in the material preparation component 100 to the welding conveyor 200. The welding conveyor 200 transports the material a to the first welding component 400, where the material a is processed on the first welding stage 401.

[0046] Specifically, material 'a' is placed in the material preparation assembly 100. The material handling assembly 300, located above material 'a', picks up material 'a' and transports it to the welding conveyor table 200. A drive roller, driven by a motor, is mounted on the upper surface of the welding conveyor table 200. Material 'a' is placed on the drive roller. Material 'a' is then transported by the drive roller to the first welding table 401, where it undergoes welding processing.

[0047] The material preparation assembly 100 and the welding conveyor table 200 are arranged side by side. This side-by-side arrangement achieves physical isolation between the material preparation and welding processes, ensuring that the two stages do not interfere with each other in terms of position. Workers at the welding station do not need to make way during material loading, thus ensuring production safety and improving production efficiency. Furthermore, the material handling assembly 300 transports material a from the material preparation assembly 100 to the welding conveyor table 200, and then the welding conveyor table 200 transfers it to the first welding assembly for processing. This automatic loading method further improves production efficiency.

[0048] In some embodiments, refer to Figure 1 and Figure 2The material handling assembly 300 includes: a support 301, which spans and connects the material preparation assembly 100 and the welding conveyor table 200; a telescopic frame 302, which is movably suspended from the support 301 and reciprocates between the material preparation assembly 100 and the welding conveyor table 200; the telescopic frame 302 is configured to extend and retract in the vertical direction; and a gripping mechanism 303, which is installed at the lower end of the telescopic frame 302 for gripping material a.

[0049] Specifically, the material handling assembly 300 transports material a from the material preparation assembly 100 to the welding conveyor table 200. A support 301 spans and connects the material preparation assembly 100 and the welding conveyor table 200. A guide rail is provided on the upper surface of the support 301, with the guide rail's transmission direction pointing from the material preparation assembly 100 to the welding conveyor table 200. A telescopic frame 302 is movably suspended from the support 301. The telescopic frame 302 is driven by a motor mounted on the support 301 to move on the support 301. The telescopic frame 302 is slidably mounted on the guide rail, and the motor drives the telescopic frame 302 to reciprocate between the material preparation assembly 100 and the welding conveyor table 200. The telescopic frame 302 is configured to extend and retract in the vertical direction, and a gripping mechanism 303 is installed at the lower end of the telescopic frame 302.

[0050] Specifically, firstly, material a is grasped: the telescopic frame 302 is positioned above the material preparation assembly 100, with its output end extending downwards to grasp material a via the gripping mechanism 303; then, material a is transported: the telescopic frame 302 retracts upwards, causing material a to leave the material preparation assembly 100. A motor on the support 301 drives the telescopic frame 302 to move along the guide rail towards the welding conveyor table 200, stopping directly above it; finally, material a is placed: the telescopic frame 302 extends downwards, stopping after contacting the welding conveyor table 200. The gripping mechanism 303 releases material a, and the telescopic frame 302 retracts upwards, returning the gripping mechanism 303 to its original position and disengaging from material a, which is then placed on the welding conveyor table 200. After material handling is completed, the telescopic frame 302 returns to its original position: a motor on the support 301 drives the telescopic frame 302 to move along the guide rail towards the material preparation assembly 100, stopping directly above it.

[0051] Through the above process, the material preparation component 100 and the welding conveyor 200 are transported across each other, realizing the isolation between the material preparation and welding processes. This ensures that the material preparation stage and the welding stage do not interfere with each other in terms of position, eliminating the need for workers to avoid certain positions, thus ensuring production safety, improving production efficiency, and achieving fully automated handling with high efficiency.

[0052] In some embodiments, the gripping mechanism 303 includes: a mounting frame 3031, mounted on the lower end of the telescopic frame 302; and a plurality of hooks 3032, which are evenly distributed on both sides of the mounting frame 3031, and each hook 3032 is used to hook the corresponding side edge of the material a.

[0053] Specifically, the mounting frame 3031 is installed at the lower end of the telescopic frame 302, and the mounting frame 3031 moves up and down as the telescopic frame 302 extends and retracts. Multiple hooks 3032 are evenly distributed on both sides of the mounting frame 3031, and each hook 3032 is used to hook the corresponding side edge of the material a, thereby gripping the material a.

[0054] Specifically, the hooks 3032 are rotatably mounted on the side of the mounting frame 3031. The downward-facing end of the hook 3032 has teeth, and the teeth of each hook 3032 face the material a. The upward-facing end of the hook 3032 is connected to the output end of a telescopic cylinder, which is mounted on the mounting frame 3031. When the telescopic cylinder extends, it drives the hooks 3032 to rotate along its rotatable connection with the mounting frame 3031, causing the teeth to move towards the material a. The hooks 3032 then press against the surface of the material a. Multiple hooks 3032 simultaneously press against the surface of the material a, thus clamping the material a. When the telescopic cylinder retracts, it drives the hooks 3032 to rotate along its rotatable connection with the mounting frame 3031, causing the teeth to move away from the material a, thus releasing the material a. The above-mentioned gripping mechanism 303 automatically grips and releases the material a, saving manpower and improving work efficiency.

[0055] In some embodiments, refer to Figure 4 The material preparation assembly 100 includes a material preparation conveyor 101, the conveying direction of which is parallel to the conveying direction of the welding conveyor 200. The material preparation conveyor 101 is configured to receive and convey material a to the material handling assembly 300 and temporarily store material a.

[0056] Specifically, the material preparation conveyor 101 has the functions of receiving and temporarily storing material a, and also has a transportation function. The material preparation conveyor 101 receives one piece of material a at a time, and material a is conveyed through the material preparation conveyor 101 to the area below the material handling assembly 300, awaiting gripping by the gripping mechanism 303. Single-piece transportation ensures that material a arrives at the material preparation assembly 100 strictly according to process requirements, avoiding production line blockage caused by multiple pieces accumulating.

[0057] In some embodiments, refer to Figure 5The material preparation assembly 100 also includes a positioning mechanism 102, which includes: a longitudinal limiting part 1021, located on the upper end face of the material preparation conveyor 101 and arranged on one side of the material preparation conveyor 101 in the transmission direction, to limit the longitudinal position of material a on the material preparation conveyor 101, wherein the longitudinal direction is perpendicular to the transmission direction of the material preparation conveyor 101; a push rod 1022, located on the upper end face of the material preparation conveyor 101 and on the opposite side to the longitudinal limiting part 1021; the push rod 1022 is used to push material a to a position that contacts the longitudinal limiting part 1021. A transverse limiting part 1023, located on the upper end face of the material preparation conveyor 101 and at the end of the material preparation conveyor 101 in the transmission direction, to limit the movement of material a at the end of the transmission direction.

[0058] Specifically, the positioning mechanism 102 is used to define the position of material a on the material preparation assembly 100. The material preparation conveyor 101 receives external material a and transports it to the area below the material handling assembly 300. Laterally, material a stops after contacting the lateral limiting part 1023, completing lateral positioning. Longitudinally, the push rod 1022 pushes material a to stop after contacting the longitudinal limiting part 1021, completing longitudinal positioning, and then waits for the hook 3032 to grasp it. The push rod 1022 and the longitudinal limiting part 1021 work together to ensure that material a is accurately positioned in both the lateral and longitudinal directions, reducing manual intervention and preventing material a from shifting or misaligning, thereby improving subsequent material handling accuracy. The lateral direction is the same as the transmission direction of the material preparation conveyor 101, and the longitudinal direction is perpendicular to the transmission direction of the material preparation conveyor 101.

[0059] Reference Figure 6 In some embodiments, the first welding assembly 400 includes: a first welding table 401 adjacent to the welding conveyor table 200, the height of the first welding table 401 being lower than the conveying height of the welding conveyor table 200; a lifting conveyor table 402 configured at the center of the first welding table 401, raised to receive material a conveyed by the welding conveyor table 200, and configured to lower to be flush with the first welding table 401 to place material a on the first welding table 401; and a reprocessing conveyor table 403 located below the welding conveyor table 200 and at the same height as the first welding table 401, for receiving the preliminary welding material a conveyed from the first welding table 401 and conveying the preliminary welding material a to a side away from the first welding assembly 400.

[0060] Specifically, material a undergoes preliminary processing at the first welding station 401, and is then transferred to the next processing station by the reprocessing transfer station 403 for the next step. When the first welding assembly 400 receives material a, the upper surface of the lifting transfer station 402 rises to be flush with the upper surface of the welding conveyor station 200, and material a is transferred to the upper surface of the lifting transfer station 402. Then, the upper surface of the lifting transfer station 402 descends to be flush with the upper surface of the first welding station 401, placing material a on the first welding station 401, where it undergoes preliminary processing.

[0061] The upper surface of the reprocessing transfer table 403 is flush with the upper surface of the first welding table 401. A gap is reserved between the reprocessing transfer table 403 and the welding conveyor table 200 to allow one material a to pass through. The lifting transfer table 402 has a driveable roller. After the material a is initially processed on the first welding table 401, the lifting transfer table 402 transports the material a to the reprocessing transfer table 403 through the driveable roller, and then the reprocessing transfer table 403 transfers the material a to the next welding station.

[0062] Reference Figure 1 The conveyor also includes a second welding assembly 500, which is located on the side of the reprocessing conveyor 403 away from the first welding assembly 400. The second welding assembly 500 receives material a from the reprocessing conveyor 403.

[0063] The second welding assembly 500 is located on the side of the reprocessing transfer table 403 away from the first welding assembly 400, reducing the lateral footprint of the conveyor frame.

[0064] Reference Figure 8 In some embodiments, the conveyor frame further includes a storage assembly 600, which includes: a storage rack 601 for temporarily storing material a; a drop-off mechanism 602 disposed on the storage rack 601; the height of the drop-off mechanism 602 is higher than the height of the preparation assembly 100, the drop-off mechanism 602 is configured to hold material a, and the drop-off mechanism 602 is configured to release material a when the discharge lifting platform 603 is raised, and to hold the upper layer of material a again after the material a has moved down by one material a thickness; a discharge lifting platform 603 disposed below the drop-off mechanism 602, the discharge lifting platform 603 is configured to rise to receive material a, and the discharge lifting platform 603 is configured to carry the material a it carries down by one material a thickness; and a conveying mechanism 604 disposed on the upper surface of the discharge lifting platform 603 for conveying material a on the surface of the discharge lifting platform 603 to the preparation conveyor 101.

[0065] The material discharge mechanism 602 includes: multiple telescopic baffles 6021, which are respectively installed on the upper end face of the storage rack 601; the telescopic direction of the telescopic baffles 6021 is perpendicular to the transmission direction of the discharge lifting platform 603.

[0066] Specifically, material 'a' is transferred by a transfer vehicle and hoisted onto the storage rack 601. The bottommost piece of material 'a' is blocked above the discharge lifting platform 603 by an extended drop-off mechanism 602. The discharge lifting platform 603 includes a lifting mechanism and a transmission mechanism. The lifting mechanism raises to carry material 'a', the drop-off mechanism 602 retracts, the lifting mechanism lowers by the thickness of one piece of material 'a', and the drop-off mechanism 602 extends again to hold the second-to-last piece of material 'a'. The discharge lifting platform 603 lowers carrying the bottommost piece of material 'a', leaving the remaining material 'a' on the storage rack 601. The lifting mechanism continues to lower to a height level with the preparation assembly 100, and the discharge lifting platform 603 transmits one piece of material 'a' to the preparation assembly 100 at a time via a conveying mechanism 604. Through the precise coordination of the drop-off mechanism 602 and the lifting mechanism, the individual separation and accurate transmission of material 'a' are achieved, improving the working efficiency of the transfer rack.

[0067] Reference Figure 3 In some embodiments, the welding conveyor 200 is located below the material handling assembly 300; and the welding conveyor 200 includes a welding transfer mechanism 201 located on the upper end face of the welding conveyor 200; the welding conveyor 200 is configured to receive material a from the material handling assembly 300 and to convey material a to the first welding assembly 400.

[0068] The welding conveyor 200 is used to receive and transfer material a. The welding conveyor 200 receives material a from the material handling assembly 300 and transports material a to the first welding assembly 400, thereby enhancing the automation level of the transfer frame.
