[0070] As Figure 1 shown, in an embodiment of the present utility model, a container chassis production line is provided, including:

[0071] An assembly table 10 for positioning and splicing the chassis 1;

[0072] A first transition table 20 is arranged at the downstream station of the assembly table 10 and adjacent to the discharge side of the assembly table 10, and is used to receive and weld one side surface of the chassis 1;

[0073] A turning table 30 is arranged at the downstream station of the first transition table 20 and adjacent to the discharge side of the first transition table 20, and is used to receive and turn over the chassis 1 so that the other side surface of the chassis 1 faces upward;

[0074] A second transition table 40 is arranged at the downstream station of the turning table 30 and adjacent to the discharge side of the turning table 30, and is used to receive and weld the other side surface of the chassis 1;

[0075] An output table 50 is arranged at the downstream station of the second transition table 40 and adjacent to the discharge side of the second transition table 40, and is used to output the welded chassis 1.

[0076] Specifically, based on the above production line, the process of manufacturing the chassis 1 in this application includes: transporting components such as the bottom beams that make up the chassis 1 to the assembly table 10 and splicing and spot-welding them to form the structure of the chassis 1; after the chassis 1 with spot-welding finalized is transferred from the assembly table 10 to the first transition table 20, the one side surface of the chassis 1 can be welded on the first transition table 20; after one side is welded, the chassis 1 is transported to the flipping table 30, and on the flipping table 30, the chassis 1 is flipped to make the other side surface of the chassis 1 face upward; the flipped chassis 1 is moved to the second transition table 40, and the other side surface of the chassis 1 can be welded on the second transition table 40; the chassis 1 with both sides welded is transferred to the output table 50, and the output table 50 outputs the welded chassis 1 to the next process.

[0077] Compared with the prior art, this application has the following advantages:

[0078] The production line of the container chassis 1 in this application can realize continuous transmission and processing of the chassis 1, without manual participation in handling and flipping, saving time and effort;

[0079] Each work station is connected in sequence, and the transmission distance of the workpiece between adjacent work stations is short, accelerating the transmission rate;

[0080] The production line can operate continuously. When one work station is processing, there are also workpieces being processed in corresponding processes on other work stations, improving the batch processing efficiency and effectively reducing the production cost;

[0081] The transmission path of the workpiece on the production line is fixed, and it is not necessary to use transfer machinery such as forklifts, avoiding safety accidents caused by hitting workers during their driving in the workshop, and ensuring production safety.

[0082] In this application, a pressing mechanism 11 can be arranged on the assembly table 10 to press the chassis 1 from above, and positioning mechanisms 12 and positioning plates 14 arranged at both ends of the conveying direction on the assembly table 10 are used to jointly abut and fix the chassis 1 from both ends, so as to ensure the stable position of the chassis 1 during spot-welding on the assembly table 10; after spot-welding is completed, the lifting mechanism 13 on the assembly table 10 lifts the chassis 1 to a height flush with the table surface of the first transition table 20, and the conveying mechanism on the assembly table 10 can rise and drive the chassis 1 to be conveyed downstream to the first transition table 20.

[0083] Reference Figure 3 and Figure 6 , in some embodiments, the first transition table 20 and / or the second transition table 40 includes a plurality of conveying rollers a arranged side by side in sequence along a preset transmission direction, and the length direction of the conveying rollers a is perpendicular to the preset transmission direction. After the welding of the chassis 1 on the surface of the first transition table 20 is completed, the conveying rollers a can be driven to rotate by a motor or the like to convey the chassis 1 forward to the workbench on the next work station.

[0084] Reference Figure 4 and Figure 5 , in some embodiments, the turning table 30 includes:

[0085] a lifting mechanism 31, adjacent to the discharge side of the first transition table 20;

[0086] a horizontal conveying mechanism 32, laid on the surface of the lifting mechanism 31, for receiving the chassis 1 output by the first transition table 20 when the lifting mechanism 31 rises and horizontally conveying the chassis 1 in the downstream direction;

[0087] a turning mechanism 33, arranged in the conveying direction of the horizontal conveying mechanism 32, for receiving and turning over the chassis 1.

[0088] Specifically, after the welding is completed on one side surface of the chassis 1 on the first transition table 20, the chassis 1 is output downstream; the lifting mechanism 31 rises, the horizontal conveying mechanism 32 receives the bottom surface of the chassis 1 and starts to continue conveying the chassis 1 downstream; when reaching the turning mechanism 33, the turning mechanism 33 turns over the chassis 1 to swap the upper and lower surfaces of the chassis 1.

[0089] In this embodiment, the lifting mechanism 31 can be lifted up and down, and the horizontal conveying mechanism 32 can move horizontally, so that it can freely adjust to the heights of the upstream first transition table 20 and the downstream second transition table 40 at the same time, with strong flexibility in use; the turning mechanism 33 is arranged in the transmission direction of the horizontal conveying mechanism 32, and can turn over the chassis 1 immediately after the conveying reaches the preset position, with convenient operation without waiting and high production operation efficiency.

[0090] Reference Figure 4 , in some embodiments, the lifting mechanism 31 includes a first lifting mechanism 311, a second lifting mechanism 312 and a third lifting mechanism 313 which are sequentially arranged at intervals along the conveying direction, and a first horizontal conveying mechanism 321, a second horizontal conveying mechanism 322 and a third horizontal conveying mechanism 323 are respectively laid on the first lifting mechanism 311, the second lifting mechanism 312 and the third lifting mechanism 313;

[0091] the turning mechanism 33 includes a plurality of turning frames 331, the plurality of turning frames 331 are sequentially arranged at intervals between every two adjacent lifting mechanisms 31, and the turning axes of the turning frames 331 are all on the same straight line.

[0092] Specifically, after the welding of one side surface of the chassis 1 on the first transition table 20 is completed, the chassis 1 is output downstream; the first lifting mechanism 311, the second lifting mechanism 312, and the third lifting mechanism 313 are simultaneously raised to support the bottom surface of the chassis 1 and rise to a height where the chassis 1 can enter the turnover frame 331 (at this time, the height exceeds the bottom plate of the limit frame 331c of the turnover frame 331). At this time, the first horizontal conveying mechanism 321, the second horizontal conveying mechanism 322, and the third horizontal conveying mechanism 323 are started to continue to convey the chassis 1 forward and pass through a plurality of turnover frames 331; the first lifting mechanism 311, the second lifting mechanism 312, and the third lifting mechanism 313 are lowered, and the plurality of turnover frames 331 support and turn over the chassis 1 so that the upper and lower surfaces of the chassis 1 are swapped; the first lifting mechanism 311, the second lifting mechanism 312, and the third lifting mechanism 313 are raised again to support the chassis 1, and the first horizontal conveying mechanism 321, the second horizontal conveying mechanism 322, and the third horizontal conveying mechanism 323 are started to continue to convey the chassis 1 forward to the second transition table 40 at the downstream station for welding of the other side surface.

[0093] In this embodiment, it is designed that the first lifting mechanism 311, the second lifting mechanism 312, and the third lifting mechanism 313 are arranged at intervals, and the turnover frame 331 is arranged between adjacent lifting mechanisms. The lifting mechanism 31 and the turnover frame 331 do not interfere with each other in the vertical direction, which can avoid the interference between the lifting mechanism 31 and the turnover frame 331 during the process of the lifting mechanism 31 lifting the chassis 1 and ensure the normal and smooth progress of production.

[0094] Reference Figure 4 and Figure 5 , in some embodiments, the turnover frame 331 includes:

[0095] A turnover ring 331a, the extending direction of the rotation axis of the turnover ring 331a is the same as the conveying direction of the horizontal conveying mechanism 32;

[0096] A turnover driving member 331b, which is meshed and connected with the outer ring of the turnover ring 331a through a gear set and is used to drive the turnover ring 331a to rotate;

[0097] A limit frame 331c, which is fixed in the turnover ring 331a, and the inner ring area of the limit frame 331c is larger than the cross-sectional area of the chassis 1 to ensure that the chassis 1 can smoothly pass through the limit frame 331c in the turnover ring for the overall turnover of the chassis 1.

[0098] Specifically, the limiting frame 331c can limit the position of the chassis 1 in the width and height directions, preventing uncontrolled movement during rotation. The flipping drive component 331b (such as a motor) is meshed and connected to the outer ring of the flipping ring 331a through a gear set. After starting, it can drive the flipping ring 331a to rotate. The flipping ring 331a synchronously drives the limiting frame 331c and the chassis 1 to rotate, so that the upper and lower surfaces of the chassis 1 are swapped.

[0099] Furthermore, a plurality of the limiting frames 331c are connected by a cross beam 331d. The cross beam 331d can connect a plurality of limiting frames 331c into a whole, enhancing the strength and stiffness of the flipping mechanism 33, thereby ensuring the stable form of the flipping mechanism 33 and the chassis 1 during the flipping process and avoiding safety accidents.

[0100] Reference Figure 7 , in some embodiments, in the direction gradually away from the second transition table 40, the feeding side and the discharging side of the output table 50 are arranged in sequence; the height of the feeding side of the output table 50 is the same as that of the second transition table 40, and the height of the discharging side of the output table 50 is lower than that of the feeding side of the output table 50.

[0101] Specifically, due to the differences in production workshops, there is a certain height difference. The operating table surface height of the production workshop where the second transition table 40 is located is higher, while the terrain of the subsequent general assembly and other production workshops is lower, and its operating table surface height is also lower. The large height difference directly increases the handling difficulty. In order to facilitate transmission and subsequent process operations, in this embodiment, the height of the feeding side of the output table 50 is set to be the same as that of the second transition table 40 to facilitate receiving the chassis 1 of the second transition table 40; the height of the discharging side of the output table 50 is set to be lower than that of the feeding side of the output table 50, and the overall shape is inclined. The chassis 1 can be transported along the inclined output table 50 to the discharging side with a lower position, facilitating the further transfer of the discharged chassis 1 to the downstream lifting transfer vehicle 60.

[0102] Reference Figure 7 , in some embodiments, the output table 50 includes:

[0103] An inclined support 51, in the direction gradually away from the second transition table 40, the height of the inclined support 51 gradually decreases;

[0104] An inclined conveying mechanism 52, laid on the surface of the inclined support 51, for conveying the chassis 1 in the direction gradually away from the flipping table 30;

[0105] A blocking mechanism 53, arranged adjacent to the lower end of the inclined support 51, for abutting and blocking the chassis 1.

[0106] Specifically, the inclined bracket 51 provides a mounting base, and the inclined conveying mechanism 52, such as a conveying chain, conveys the chassis 1 in a direction gradually away from the turning table 30; due to the action of gravity, the chassis 1 is conveyed from top to bottom at a relatively fast speed, and the chassis itself has a large weight. In order to prevent the chassis 1 from rushing downward and hitting workers or equipment and causing safety accidents, the blocking mechanism 53 at the lower end of the inclined bracket 51, such as a cylinder-driven baffle, can abut against the chassis 1 to prevent the chassis 1 from rushing out and causing safety accidents; when blocking and limiting are not required, the cylinder drives the baffle to fall.

[0107] refer to Figure 1 , in some embodiments, further comprising:

[0108] A lifting transfer vehicle 60 is provided at a downstream position of the output platform 50 and adjacent to the output platform 50, and is used to be lifted to a position having the same height as the discharge side surface of the output platform 50 to receive and transfer the bottom frame 1 outputted from the output platform 50;

[0109] The final assembly conveying platform 70 is disposed at a downstream station of the lifting and transferring vehicle 60 and is used to receive the chassis 1 on the lifting and transferring vehicle 60 for final assembly.

[0110] Specifically, in order to facilitate the final assembly into a container, the lifting transfer vehicle 60 can be lifted to a position at the same height as the discharge side of the output platform 50 to receive the chassis 1, carry the chassis 1, and transport it to a position adjacent to the final assembly conveying platform 70, and then convey the chassis 1 to the final assembly conveying platform 70; the final assembly conveying platform 70 can be lifted to the same height as the lifting transfer vehicle 60, receive the chassis 1 on the lifting transfer vehicle 60, and assemble it into a container.

[0111] refer to Figure 8 In some embodiments, the lifting and transferring vehicle 60 includes:

[0112] The lifting platform 61 is used to be lifted to a position having the same height as the discharge side of the output platform 50 to receive the bottom frame 1;

[0113] The conveyor 63 is provided on the surface of the lifting platform 61 and is used to convey the chassis 1 to the final assembly conveying platform 70;

[0114] The walking portion 62 is disposed at the bottom of the lifting platform 61 and is used for walking between the output platform 50 and the final assembly conveying platform 70 .

[0115] Specifically, when the lifting and transfer vehicle 60 of this embodiment is working, the lifting platform 61 can be lifted to a position with the same height as the discharge side of the output platform 50 to receive the base frame 1. The walking part 62 at the bottom can carry the base frame 1 and transport it to a position adjacent to the final assembly conveying platform 70. Then, the conveyor 63 on the surface of the lifting platform 61 transports the base frame 1 to the final assembly conveying platform 70. The lifting and transfer process is smooth, and the transfer operation is flexible and fast.

[0116] It should be noted that, according to the length specification of the produced chassis 1, one machine tool can be set on each station of the production line, or two or more machine tools can be continuously set; and each of the above-mentioned conveying mechanisms can adopt a conventional conveying chain structure or a conveying roller, etc., and the lifting mechanism can adopt a lift in the prior art, such as a scissor lift, etc. The present application does not limit this.
