Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Vehicle door sills are a crucial component of automotive safety structures, providing support and protection in side collisions or rollovers to reduce injuries to occupants. Door sill reinforcement beams are typically bolted to the vehicle body. Due to the large number of bolts, precise assembly accuracy cannot be guaranteed. When using automated bolt tightening systems on vehicle assembly lines, bolt jamming frequently occurs during the bolt feeding process, impacting the assembly line's OEE (Outcome Effectiveness). Furthermore, the automatic bolt tightening process requires high precision in bolt pickup and the positioning of the body hinge mounting holes during bolt tightening, leading to frequent tightening alarms. For high-cycle production lines, equipment failures cause line shutdowns, resulting in insufficient production capacity without a backup plan.

[0025] like Figure 1 As shown, in order to address the above-mentioned problems, this application provides a door sill reinforcement beam assembly system for automatically assembling the door sill reinforcement beam 11 onto the vehicle body 12 and fixing the door sill reinforcement beam 11 onto the vehicle body 12 by fasteners, such as bolts.

[0026] like Figure 1 and Figure 2 As shown, the sill reinforcement beam assembly system in this embodiment includes: a vehicle body transfer device 1, a feeding system 2, a component gripping device 3, a positioning device 4, a fastening device 5, and a fastener conveying system 6. Among them,

[0027] The body transfer device 1 is used to carry the body 12, so that the body 12 can be placed stably on the body transfer device 1, and to move the body 12, so that the body 12 can move from one station to the next station on the vehicle assembly line.

[0028] The loading system 2 is located on one side of the vehicle body transfer device 1 and is used to supply the sill reinforcement beams 11 to the vehicle body 12. Since sill reinforcement beams 11 are installed on both the left and right sides of the vehicle body 12, the loading system 2 located on one side of the vehicle body transfer device 1 must be able to supply sill reinforcement beams 11 to both sides of the vehicle body 12.

[0029] Furthermore, the loading system 2 includes a fixed material platform 21 and a material conveying device 22. The fixed material platform 21 is fixedly disposed on one side of the vehicle body conveying device 1, and a sill reinforcement beam 11 is placed on it to supply the sill reinforcement beam 11 to the vehicle body 12 on the side of the vehicle body conveying device 1 where the fixed material platform 21 is located; for example, if the fixed material platform 21 is arranged on the left side of the vehicle body conveying device 1, then the fixed material platform 21 supplies the sill reinforcement beam 11 to the left side of the vehicle body 12. The material conveying device 22 is disposed adjacent to the fixed material platform 21 and is used to supply the sill reinforcement beam 11 to the other side of the vehicle body 12. The material conveying device 22 can transport the sill reinforcement beam 11 to the other side of the vehicle body conveying device 1 via a conveyor belt to supply the sill reinforcement beam 11 to the other side of the vehicle body 12 (e.g., the right side of the vehicle body 12).

[0030] If fixed material platforms 21 are arranged on both sides of the vehicle body transfer device 1, not only will a certain space be required on the other side of the vehicle body transfer device 1 for arranging the fixed material platforms 21, but a dedicated loading personnel will also be needed, thus requiring two loading personnel to complete the loading work. This application only sets one fixed material platform 21 on one side of the vehicle body transfer device 1 to supply the door sill reinforcing beam 11 to one side of the vehicle body 12, while setting a material transfer device 22 to supply the door sill reinforcing beam 11 to the other side of the vehicle body 12; and only one loading personnel is needed at the fixed material platform 21 (e.g., on the left side of the vehicle body 12) to simultaneously load the fixed material platform 21 and the material transfer device 22, supplying the door sill reinforcing beam 11 to both sides of the vehicle body 12. Compared with setting two fixed material platforms 21 on both sides of the vehicle body transfer device 1, this not only saves the process area of ​​the assembly line, but also saves one loading personnel, reducing labor costs.

[0031] The component gripping device 3 is disposed on both sides of the vehicle body transfer device 1, and is used to place the sill reinforcement beam 11 onto the positioning device 4 disposed on the vehicle body transfer device 1, thereby positioning the sill reinforcement beam 11 relative to the vehicle body 12. The component gripping device 3 can be two handling robots disposed on both sides of the vehicle body transfer device 1. One handling robot is arranged near the fixed material table 21, and is used to grip the sill reinforcement beam 11 from the fixed material table 21 and assemble it onto the vehicle body 12; the other handling robot is arranged on the other side of the vehicle body transfer device 1, and is used to grip the sill reinforcement beam 11 from the material transfer device 22 and assemble it onto the vehicle body 12 on that side. Then, the positioning device 4 disposed on both sides of the vehicle body transfer device 1 positions the sill reinforcement beam 11 relative to the vehicle body 12 to ensure the relative positional accuracy of the sill reinforcement beam 11 and the vehicle body 12.

[0032] Furthermore, after the sill reinforcement beam 11 is positioned by the positioning device 4, before it is finally fixedly connected to the vehicle body 12, in order to prevent the sill reinforcement beam 11 from shifting relative to the vehicle body 12 in subsequent processes, welding devices 7 are also provided on both sides of the vehicle body transfer device 1 for positioning welding of the positioned sill reinforcement beam 11. The welding devices 7 can be two handling robots set on both sides of the vehicle body transfer device 1, which respectively position and weld the sill reinforcement beam 11 on both sides of the vehicle body 12 to the vehicle body 12, ensuring that the sill reinforcement beam 11 does not move along the X-axis direction of the vehicle body 12 coordinate system.

[0033] Furthermore, a position correction fixture 8 is also provided in the vehicle body transfer device 1, located outside the sill reinforcement beam 11, for calibrating the position of the sill reinforcement beam 11 after welding and positioning. After the positioning welding of the sill reinforcement beam 11 is completed, in order to ensure the accuracy of the relative position between the sill reinforcement beam 11 and the vehicle body 12, the position of the sill reinforcement beam 11 relative to the vehicle body 12 must be corrected by the position correction fixture 8 before finally fixing the sill reinforcement beam 11 to the vehicle body 12. The position correction fixture 8 can move to a set position along the Y-axis direction of the vehicle body 12 coordinate system under external force, thereby correcting whether the positioning of the sill reinforcement beam 11 in the Y-axis and Z-axis directions of the vehicle body 12 coordinate system is accurate.

[0034] Subsequently, the sill reinforcement beam 11 is fixedly connected to the vehicle body 12 using fasteners via fastening devices 5 located on both sides of the vehicle body transfer device 1. The fastening devices 5 can be two tightening robots located on both sides of the vehicle body transfer device 1. Fastener delivery systems 6 are also provided on both sides of the vehicle body transfer device 1, which are connected to the fastening devices 5 and are used to supply fasteners (e.g., bolts) to the fastening devices 5.

[0035] Furthermore, such as Figure 3 As shown, the fastener conveying system 6 includes a fastener hopper 61, a fastener storage module 62, and a blowing module 63. The fastener hopper 61 stores fasteners. The fastener storage module 62 is connected to the fastener hopper 61 and retrieves one fastener from the hopper 61 at a time for temporary storage. The blowing module 63 is connected to the fastener storage module 62 via a transparent transmission pipeline, receives the fasteners stored in the fastener storage module 62, and blows them to the end of the blowing module 63.

[0036] By connecting the fastener storage module 62 and the blowing module 63 with a transparent transmission pipeline, the position and transmission trajectory of the fasteners can be clearly seen during the fastener transportation process, enabling full-process tracking of the fastener transportation process.

[0037] The blowing module 63 is equipped with a gripper (not shown in the figure) at its end for clamping the fasteners blown to the end of the blowing module 63, so that the fastening device 5 can perform a capping operation on the fasteners. Then, the fastening device 5 uses an automatic capping mechanism to attract the fasteners to the tightening head, and then the fastening device 5 automatically moves to the corresponding position to tighten the fasteners one by one onto the vehicle body 12, completing the automatic tightening of the sill reinforcement beam 11.

[0038] The tightening head of the fastening device 5, through its floating design, can automatically recognize the cap even when the position of the fastener deviates by 1.5 to 2 mm, ensuring sufficient self-adaptability of the tightening module.

[0039] Furthermore, a sensor (not shown in the figure) is installed on the gripper to detect whether a fastener is clamped on the gripper. By installing a sensor on the gripper to detect the presence or absence of fasteners, closed-loop control of fastener transmission is achieved, avoiding the problem of repeated fastener feeding.

[0040] Furthermore, the fastener delivery systems 6 arranged on both sides of the vehicle body transmission device 1 are interconnected via transmission pipelines. With this arrangement, even if a fastener delivery system 6 on one side of the vehicle body transmission device 1 experiences a fastener feeding failure, the fastener delivery system 6 on the other side can reliably and continuously deliver fasteners to the faulty side, thus ensuring the supply of fasteners.

[0041] like Figure 2 and Figure 3 As shown, the sill reinforcement beam assembly system in this embodiment also includes an air supply device 9, which is connected to the fastener conveying system 6 and provides constant-pressure gas to the fastener conveying system 6. Through the air supply device 9, the fasteners stored in the fastener storage module 62 can enter the blowing module 63; and then the fasteners are blown to the gripper at the end of the blowing module 63.

[0042] In one specific embodiment, the air supply device 9 can be a dual-tank pressure stabilization system, with a constant-pressure air tank installed on each side of the vehicle body transmission device 1 to ensure a continuous and stable air pressure for the fastener delivery system 6 connected to it. Furthermore, the air circuits of the two air tanks are interconnected, so even if one air tank fails, the other can still maintain a stable air pressure output, preventing jamming problems caused by unstable air pressure during fastener transmission.

[0043] Furthermore, the sill reinforcement beam assembly system in this embodiment also includes a control device (not shown in the figure), connected to the fastening device 5, for acquiring the torque value applied by the fastening device 5 to each fastener and determining whether the torque value is qualified. The control device includes a control display screen 10 and an alarm device. The control display screen 10 displays the torque value applied by the fastening device 5 to each fastener and indicates whether each torque value is qualified. When any torque value is unqualified, the alarm device issues an alarm.

[0044] By transmitting the fastener torque value to the control display screen 10 in real time through the control device and setting the alarm device, the operator can quickly identify the faulty fastener and repair it in time, without causing the line to stop due to handling the fault.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, when using the sill reinforcement beam assembly system in this embodiment, the vehicle body 12 is assembled according to the vehicle body transfer device 1. Figure 2 The material is transferred from right to left. The door sill reinforcement beam 11 is divided into left and right parts. To reduce labor costs and save processing space, both left and right door sill reinforcement beams 11 are designed to be loaded onto the left side of the vehicle body 12. The right door sill reinforcement beam 11 is loaded onto the material transfer device 22, which transfers it to the right side of the vehicle body 12 line. The component gripping device 3 (transfer robot) located on the right side of the vehicle body transfer device 1 picks up the right door sill reinforcement beam 11 from the material transfer device 22 and assembles it onto the right side of the vehicle body 12. The left door sill reinforcement beam 11 is loaded onto the fixed material table 21, picked up by the component gripping device 3 (transfer robot) located on the left side of the vehicle body transfer device 1, and assembled onto the left side of the vehicle body 12.

[0046] Then, the positioning devices 4 located on the left and right sides of the vehicle body transfer device 1 are used to position the left and right sill reinforcement beams 11 to ensure the relative positional accuracy between the sill reinforcement beams 11 and the vehicle body 12. After positioning, the welding device 7 (welding robot) performs positioning welding on the left and right sill reinforcement beams 11 respectively, completing the positioning of the sill reinforcement beams 11 to the vehicle body 12. After welding, the positioning devices 4 automatically open, and the vehicle body transfer device 1 automatically transfers the vehicle body 12 to the next station and completes the positioning.

[0047] At the next workstation, the position correction fixture 8 calibrates the dimensions and position of the sill reinforcement beam 11 and completes its final positioning. The fastener conveying system 6 automatically transports the fasteners (hereinafter referred to as bolts) distributed on the left and right sides of the body transfer device 1 to the corresponding fastening device 5 (tightening robot). The fastening device 5 uses an automatic cap recognition mechanism to attract the bolts to the tightening head. Then, the fastening device 5 automatically moves to the corresponding position and tightens the bolts one by one onto the body 12, completing the automatic tightening of the sill reinforcement beam 11. The tightening result of each bolt is transmitted and displayed on the control display screen 10 set at the quality inspection station via PLC. The quality inspection confirms and ensures the final tightening result. After confirmation, the body 12 is transferred to the next workstation via the body transfer device 1. At this point, the assembly and tightening process of the sill reinforcement beam 11 is completed.

[0048] In addition, taking into account possible malfunctions during equipment operation, the assembly and tightening system of the threshold reinforcement beam 11 also fully considers the backup degraded production plan to ensure that the production line can continue to operate even if some vulnerable equipment is damaged.

[0049] In addition to the air supply device 9, which is a dual-tank pressure stabilization system, as described above, the fastener conveying system 6, located on both sides of the body transmission device 1, is also interconnected via transmission pipelines. The fastening devices 5 on both sides of the body transmission device 1 can also automatically tighten the sill reinforcement beam 11 on the other side. Considering the high failure rate of the sill reinforcement beam assembly system, even in the event of partial or complete system failure, manual tightening capability is provided at the quality inspection station, and degraded production can be carried out on multiple production lines. Through the implementation of these backup plans, the operating rate of the production lines is fully guaranteed.

[0050] In addition, when designing the door sill reinforcement beam 11 and the body 12, it is also necessary to perform a full system dimensional chain calculation and decomposition, and to fully consider the manufacturing tolerances and manufacturing process stability of the matching parts, so as to prevent misaligned holes from affecting the assembly and tightening quality during the final assembly and tightening process.

[0051] This application also provides a vehicle assembly line that includes the sill reinforcement beam assembly system described above.

[0052] The sill reinforcement beam assembly system in this embodiment automatically assembles the sill reinforcement beam 11 and pre-positions it using welding, achieving precise positioning and repeatability of the sill reinforcement beam 11, preventing misaligned holes from affecting tightening quality. The entire process systematically saves labor costs, improves the stability of the sill reinforcement beam 11 assembly, has high assembly efficiency, and increases the first-pass yield and assembly line uptime. Simultaneously, the system systematically considers various degradation schemes to ensure the production line can operate continuously, stably, and efficiently.

[0053] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
