For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or the interaction between two components.

[0038] With technological advancements and the growth of the automotive industry, cars have become a must-have for both home and travel. Car doors not only serve as a gateway for drivers and passengers to enter and exit the vehicle, but also play an indispensable role in shielding drivers and passengers from external interference, mitigating side impacts, protecting the safety of drivers and passengers, providing a comfortable riding environment, and enhancing the vehicle's overall aesthetics. The appearance quality of car doors is crucial not only to the vehicle's manufacturing process but also to its overall quality and user experience. Consequently, strict control is required of both door dimensions (clearance and surface difference) and the quality of the exposed surface (including pits, bumps, embossing, and unevenness).

[0039] This requires a thorough inspection of the door assembly after it's been hemmed or rolled at the end of the welding shop's door production line to ensure that no quality issues are exposed. To ensure production efficiency, the subsequent processing steps and inspection personnel for the door assembly after pressing or hemming are typically organized into a production line sequence: feeder—arc welding or spot welding of the door—door hinge installation—inspection and polishing of the door inner panel—inspection and polishing of the door outer panel—door mounting. Door assemblies typically weigh approximately 30-50 pounds (15-20 catties). There are two common methods for transferring door assemblies between processes: 1. Manual handling from one process to the next; 2. Using an auxiliary robotic arm or lifting device to lift the door and transfer it to the next process. Therefore, existing manual door handling lines after pressing or hemming present the following problems: ① Manual handling is required to transfer the door between processes, which is labor-intensive, wastes a lot of effort, and reduces production efficiency. ② Multiple handling can easily lead to quality issues such as secondary damage. ③ If a vehicle design requires the installation of door hinges on the door cover line, the door must be transported and precisely placed on the hinge fixture. Careless handling can cause the door to collide with the hinge fixture, causing secondary damage. After the hinge is installed, it must be removed from the fixture and passed to the next process. ④ Using an auxiliary hoist or robotic arm to pass the door to the next process is expensive. ⑤ Using an auxiliary hoist or robotic arm requires a complex process: aligning the door, securing it, lifting it, moving it, lowering it, and releasing it. This reduces production efficiency and requires high employee proficiency.

[0040] Based on this, the present application proposes a vehicle door processing system 100. By providing a transport assembly 5 on each vehicle door processing mechanism that can independently transport vehicle doors, each vehicle door processing mechanism can be transported independently without interfering with each other. Furthermore, since each vehicle door processing mechanism has the ability to transport vehicle doors, it can reduce the difficulty of handling vehicle doors for operators and improve the efficiency of vehicle door processing. Furthermore, the vehicle door processing system 100 of the present application can flexibly process different types of vehicle doors, with high flexibility and strong practicality.

[0041] Reference below Figure 1-Figure 7 A vehicle door processing system 100 according to an embodiment of the present invention is described.

[0042] like Figure 1 As shown, the vehicle door processing system 100 according to an embodiment of the present invention includes a feeding mechanism 10, a material rack, and a plurality of vehicle door processing mechanisms arranged in sequence along a first direction X between the feeding mechanism 10 and the material rack. Each vehicle door processing mechanism is provided with a transport component 5 for transporting the vehicle door along the first direction X. The vehicle door processing mechanism can process the vehicle door located on the transport component 5, wherein, between two adjacent vehicle door processing mechanisms, the vehicle door is suitable for being moved from one transport component 5 to another transport component 5.

[0043] For example, in combination Figure 2-Figure 6, each car door processing mechanism can perform different processing operations on the car door. For example, the multiple car door processing mechanisms are respectively a first mechanism 1, a second mechanism 2, a third mechanism 3 and a fourth mechanism 4. After the car door is edged or rolled by the press, it can be transported to the first mechanism 1 through the feeding mechanism 10. The first mechanism 1 can weld the car door. After the welding is completed, the transportation component 5 of the first mechanism 1 is the first transportation component 12. The first transportation component 12 can transport the car door toward the second mechanism 2. The transportation component 5 of the second mechanism 2 is the second transportation component 22. When part of the car door moves from the first transportation component 12 to the second transportation component 22, the second transportation component 22 can cooperate with the first transportation component 12 to transport the car door until the car door is completely moved to the second transportation component 22. When the car door is transported to the second transportation component 22, the second mechanism 2 can fix the hinge on the car door. After the hinge is fixed, the second transportation component 22 can transport the car door toward the third mechanism 3. The transportation component 5 of the third mechanism 3 is the third transportation component 32. When the car door After the door is partially moved from the second transport component 22 to the third transport component 32, the third transport component 32 can cooperate with the second transport component 22 to transport the door until the door is fully moved to the third transport component 32. When the door is transported to the third transport component 32, the appearance of the door can be inspected. For example, the third mechanism 3 can be provided with multiple, for example, two, which can detect the two sides of the door separately, thereby improving the detection efficiency. After the door is inspected on one or two third mechanisms 3, the third transport component 32 can transport the door toward the fourth mechanism 4. The transport component 5 of the fourth mechanism 4 is the fourth transport component 43. When the door moves from the third transport component 32 to the fourth transport component 43, the fourth mechanism 4 can be a transport trolley, which can transport the door to a designated position. Moreover, since the fourth mechanism 4 is provided with the fourth transport component 43, the door can better leave the fourth mechanism 4 from the fourth transport component 43, and the position of the door after leaving the fourth mechanism 4 can also be better controlled.

[0044] Moreover, it can be seen from the above content that in the present application, a transport component 5 that can independently transport the door is provided on each door processing mechanism, so that each door processing mechanism can be transported independently without interfering with each other. At the same time, since each door processing mechanism has the ability to transport the door, it can reduce the difficulty of the operator in carrying the door, improve the processing efficiency of the door, and the door is not easily damaged during transportation, which can better ensure the quality of the door.

[0045] For example, a plurality of door processing mechanisms can be made into an assembly line, such as the first mechanism 1 to the fourth mechanism 4 in the above example. For some types of doors, the hinges may need to be assembled independently. Therefore, when processing this type of door, the door can pass directly through the second transport component 22 without stopping. Therefore, the door processing system 100 of the present application can flexibly process different types of doors, and is highly flexible and practical.

[0046] Thus, according to the vehicle door processing system 100 of the embodiment of the present invention, by providing a transport assembly 5 capable of independently transporting vehicle doors on each vehicle door processing mechanism, each vehicle door processing mechanism can be transported independently without interfering with each other. At the same time, since each vehicle door processing mechanism has the ability to transport vehicle doors, the operator's handling difficulty of the vehicle doors can be reduced, thereby improving the efficiency of vehicle door processing. Furthermore, the vehicle door processing system 100 of the present application can flexibly process vehicle doors of different models, with high flexibility and strong practicality. Moreover, the vehicle doors are not easily damaged during transportation, which can better ensure the quality of the vehicle doors.

[0047] In some embodiments of the present invention, Figure 7 As shown, the transport assembly 5 includes: a roller bracket 51 and a plurality of rollers 52 . The plurality of rollers 52 are rotatably mounted on the roller bracket 51 , and the plurality of rollers 52 are arranged in sequence along the first direction X.

[0048] like Figure 1 and Figure 7 As shown, multiple rollers 52 are arranged in a row along the first direction X. For example, when the car door is on the transport assembly 5, the operator can assist in holding the car door and give the car door some pushing force to make the car door "walk" on the multiple rollers 52; for example, it can also be driven by a device that can automatically drive the car door, and this application does not impose any restrictions.

[0049] In the above example, the contact between the vehicle door and the transport component 5 is rolling contact, so the friction between the vehicle door and the transport component 5 can be reduced well, reducing the risk of damage to the vehicle door.

[0050] For example, the roller 52 may be cylindrical or spherical, and this application does not impose any limitation thereto.

[0051] Exemplarily, the roller 52 is cylindrical, and a V-shaped groove is provided on the cylindrical surface of the roller 52, so as to better limit the position of the vehicle door in the axial direction of the roller, which is beneficial to the stable transportation of the vehicle door.

[0052] In some embodiments of the present invention, the roller bracket 51 includes a plurality of roller shafts arranged sequentially along a first direction X. The axis of each roller shaft extends along a second direction Y. A plurality of rollers 52 are mounted on the roller shafts in a one-to-one correspondence, with the first direction X and the second direction Y being perpendicular to each other. Thus, the plurality of rollers 52 rotate independently and independently of each other. The rollers 52 rotating about their axes can effectively transport the vehicle door along the first direction X as they roll.

[0053] In some embodiments of the present invention, Figure 3 As shown, one of the multiple door processing mechanisms is the first mechanism 1, which includes: a first bracket 11, a first transport component 12 and a first drive component 13. The first bracket 11 includes a base plate and a leaning rod 18. The leaning rod 18 is arranged on at least one side of the base plate in the second direction Y. The first direction X and the second direction Y are perpendicular to each other. The first transport component 12 can be moved up and down on the first bracket 11. The door is suitable for being placed on the first transport component 12 and suitable for leaning against the leaning rod 18 on the side of the base plate in the second direction Y; the first drive component 13 is arranged on the first bracket 11, wherein the material table of the feeding mechanism 10 and the material table of the material rack are spaced apart in the up and down directions, and the first drive component 13 is used to drive the first transport component 12 to move up and down so that the door on the feeding mechanism 10 can be smoothly transported to the material rack.

[0054] For example, the material table of the feeding mechanism 10 can be composed of a belt conveyor assembly. In actual production, if the material table of the feeding mechanism 10 is higher than the material table of the material rack, the car door often needs to be moved during the processing of the car door. In this way, the car door is easily damaged during the process of lifting, transporting and lowering the car door. The first mechanism 1 of the present application, after the feeding mechanism 10 transports the car door to the predetermined position, the first driving assembly 13 of the first mechanism 1 can drive the first transport assembly 12 to move upward, so that the material table of the feeding mechanism 10 and the conveying plane of the first transport assembly 12 are basically at the same horizontal height, so that the car door can be directly dragged from the material table of the feeding mechanism 10 to the first transport assembly 12, and the car door on the first transport assembly 12 can be leaned against the leaning rod 18. At this time, it is convenient to perform operations such as welding on the car door.

[0055] When the welding process of the car door is completed, the first driving component 13 can be used to drive the first transport component 12 to move downward again, so that the conveying plane of the first transport component 12 is basically at the same height as the conveying plane of the subsequent car door processing mechanism, or the conveying plane of the first transport component 12 is basically at the same height as the material platform of the material rack, so that the car door located in the first transport component 12 can be directly transported by dragging, which can better reduce the risk of damage to the car door and better improve the efficiency of car door transportation.

[0056] Exemplarily, the first driving assembly 13 can be a telescopic pneumatic cylinder, a telescopic hydraulic cylinder, or a driving motor and a connecting rod in transmission connection with the driving motor, and the application does not limit the above examples.

[0057] Exemplarily, the leaning rods 18 are arranged on both sides of the second direction Y of the bottom plate, so that the door can be leaned on any one of the leaning rods 18 according to actual welding requirements, thereby meeting the processing requirements.

[0058] In some embodiments of the utility model, as shown in Figure 3 The first mechanism 1 further comprises a first chassis 14, a second driving assembly 15, a limiting piece 16 and a first controller 17, the first support 11 is rotatably arranged on the first chassis 14, the second driving assembly 15 is used for driving the first support 11 to rotate around an axis perpendicular to a horizontal plane, the limiting piece 16 is used for limiting the rotation angle of the first support 11, and the first controller 17 is arranged on the first support 11.

[0059] That is to say, when the door on the first mechanism 1 is welded, the first mechanism 1 can be controlled according to actual requirements, so that the door angle is adjusted by controlling the first mechanism 1, thereby facilitating the welding of the door at different angles, reducing the activity amount of the operator when welding the door, that is, the door rotates, and the operator can weld the door at different positions and different angles without moving, thereby improving the operation efficiency and reducing the operation difficulty. The limiting piece 16 can limit the rotation angle of the first support 11, that is, the first support 11 can be positioned by the limiting piece 16, and the rotation accuracy of the first support 11 can be improved.

[0060] In addition, the application can improve the operation convenience by controlling through the first controller 17. In the application, the first controller 17 and the second controller and the like in the following text take the first controller 17 as an example, which can be manually started and stopped by the operator to control the driving time and driving stroke of the first driving assembly 13 and the second driving assembly 15 through the first controller 17, or the operator only needs to trigger the first controller 17 once, and the first driving assembly 13 or the second driving assembly 15 directly drives to the predetermined position according to the predetermined program. The application does not limit this, and the second controller and the like in the following text are not described in detail.

[0061] In some embodiments of the utility model, as shown in Figure 4As shown, one of the multiple door processing mechanisms is the second mechanism 2, which includes: a second chassis 21, a second transport component 22, a second bracket 23 and a plurality of clamping components 24, the second transport component 22 is arranged on the second chassis 21; a first positioning member 28 is provided on the second bracket 23, and the first positioning member 28 is used to limit the position of the door on the second transport component 22 in the first direction X; the multiple clamping components 24 are all located on the second bracket 23, and the multiple clamping components 24 are all suitable for clamping the door.

[0062] For example, a hinge may be added to the second mechanism 2 for the vehicle door. Therefore, the vehicle door needs to be stably clamped by the second mechanism 2 to ensure reliability and precision when the hinge is added.

[0063] In some embodiments of the present invention, the second mechanism 2 also includes a third bracket 25, a third drive assembly 26 and a second control member 27. The third bracket 25 is rotatably mounted on the second bracket 23, and the rotation axis of the third bracket 25 extends along the first direction X; the third drive assembly 26 is used to drive the third bracket 25 to rotate so that the vehicle door rotates from a first position on the second transport assembly 22 to a second position separated from the second transport assembly 22. When the vehicle door is in the second position, multiple clamping assemblies 24 are suitable for clamping the vehicle door; the second control member 27 is arranged on the second chassis 21, and the second control member 27 controls the third drive assembly 26.

[0064] That is to say, in this example, the third drive assembly 26 can be used to drive the third bracket 25 to rotate, thereby lifting the car door from the second transport assembly 22. In this way, when the hinge is added to the car door, the damage to the second transport assembly 5 can be reduced. After the hinge is added, the second drive assembly 15 can drive the third bracket 25 to reverse, thereby placing the car door back on the second transport assembly 22. At this time, the operator can manually support the car door to rotate on the second transport assembly 22, so that the car door is disengaged from the first positioning member 28, so that the car door can continue to be transported on the second transport assembly 22.

[0065] In some embodiments of the present invention, Figure 5 As shown, one of the multiple door processing mechanisms is the third mechanism 3, which includes: a third chassis 31, a third transport assembly 32, a fourth bracket 33, a fourth drive assembly 34 and a third control component 35; the third transport assembly 32 is arranged on the third chassis 31; the fourth bracket 33 is rotatably mounted on the third chassis 31, and the rotation axis of the fourth bracket 33 extends along the first direction X; the fourth drive assembly 34 is used to drive the fourth bracket 33, so that the door located on the third transport assembly 32 is carried on the fourth bracket 33 and rotates with the fourth bracket 33; the third control component 35 is arranged on the third chassis 31, and the third control component 35 controls the fourth drive assembly 34.

[0066] Therefore, when the vehicle door is inspected and polished on the third mechanism 3, the third control component 35 can control the fourth drive assembly 34 so that the fourth drive assembly 34 drives the fourth bracket 33 to rotate, for example, the fourth bracket 33 rotates upward, so that the bottom of the vehicle door can be better seen by the operator, thereby reducing the difficulty of inspecting the vehicle door and improving the inspection efficiency.

[0067] For example, two third mechanisms 3 are provided, and in the second direction Y, the rotation axes of the two fourth brackets 33 are respectively located on both sides of the third transport assembly 32. In this way, different sides of the door can be independently inspected and polished at different workstations, which can improve work efficiency.

[0068] In some embodiments of the present invention, Figure 6 As shown, one of the multiple door processing mechanisms is the fourth mechanism 4, which includes: a fifth chassis 41, a fifth bracket 42, a fourth transport assembly 43, and a handle 44. The fifth chassis 41 is provided with a slide rail 45 extending along the second direction Y; the fifth bracket 42 is provided with a pulley that cooperates with the slide rail 45; the fourth transport assembly 43 is provided on the fifth bracket 42; and the handle 44 is provided on the fifth bracket 42. Therefore, when the door moves from the third transport assembly 32 to the fourth transport assembly 43, the fourth mechanism 4 can serve as a transport trolley that can transport the door to a designated location. Furthermore, since the fourth mechanism 4 is provided with the fourth transport assembly 43, the door can be easily removed from the fourth mechanism 4 from the fourth transport assembly 43, and the position of the door after leaving the fourth mechanism 4 can also be easily controlled.

[0069] For example, the roller 52 may be made of iron, and a nylon material is provided on the surface of the roller 52 .

[0070] Please refer to the following Figure 1-Figure 7 A vehicle door processing system 100 according to a specific embodiment of the present invention is described.

[0071] The vehicle door processing system 100 includes a feeding mechanism 10, a material rack, and a plurality of vehicle door processing mechanisms arranged in sequence along a first direction X between the feeding mechanism 10 and the material rack. Each vehicle door processing mechanism is provided with a transport component 5 for transporting the vehicle door along the first direction X. The vehicle door processing mechanism can process the vehicle door located on the transport component 5, wherein, between two adjacent vehicle door processing mechanisms, the vehicle door is suitable for being moved from one transport component 5 to another transport component 5.

[0072] Each vehicle door processing mechanism can perform different processing operations on the vehicle door. For example, the multiple vehicle door processing mechanisms are respectively a first mechanism 1 , a second mechanism 2 , a third mechanism 3 and a fourth mechanism 4 .

[0073] The feeding mechanism 10 can convey the door assembly after rolling. The first mechanism 1 can be at a manual welding station, that is, welding the door on the first mechanism 1. The second mechanism 2 can be at a manual hinge installation station. The two third mechanisms 3 can be at a manual door inner panel inspection and polishing station and a manual door outer panel inspection and polishing station respectively. The fourth mechanism 4 can be a door mounting frame.

[0074] Employees pull or drag the car door to transfer between processes, which greatly reduces the labor intensity of employees, improves production efficiency, and reduces the high investment cost of auxiliary lifting equipment or robotic arms, difficult operation, complex operation and low efficiency.

[0075] A vehicle door processing system 100 employs the following operating steps: ① After the door assembly is lowered to the stop position of the feeding mechanism 10, a worker ② straightens the door from the feeding mechanism 10 and drags or pulls it onto the transport assembly 5 of the first mechanism 1. The worker gently lowers the door so that it leans or rests against the support rod 18, performing manual arc welding or spot welding. After the work is completed, the worker drags or pulls the door to the operator of the second mechanism 2. ③ The operator of the second mechanism 2 takes over the door from the operator of the first mechanism 1 midway, continues to pull or pull the door to the second mechanism 2, completes the hinge installation and other operations, and then pulls or pulls the door to the operator of the first third mechanism 3. ④ The operator of the first third mechanism 3 takes over the door from the operator of the second mechanism 2 midway, continues to pull or pull the door to inspect the inner panel, and after completing the operation, pulls or pulls the door to the operator of the second third mechanism 3. ⑤ The operator of the second third mechanism 3 takes over the door from the operator of the first third mechanism 3 midway, continues to pull or pull the door to inspect the outer panel, and after completing the operation, pulls or pulls the door to the operator of the fourth mechanism 4. ⑥ The operator of the fourth mechanism 4 takes over the door from the operator of the second third mechanism 3 midway, continues to pull or pull the door to the sliding trolley (i.e., the fifth mechanism), and gently lowers it so that the door leans against or rests on the leaning rod 18 or the backrest. ⑦ The fifth operator pulls the handle 44 of the sliding trolley to align the door on the trolley with the V-groove of the material rack. The operator then aligns the door from the trolley and pulls or drags the door assembly into the material rack. This process is repeated repeatedly to complete the entire door rack process. Finally, the qualified door assembly is sent to the welding assembly line for assembly.
