The body-in-white is assembled by hundreds of sheet metal parts through stamping, welding, riveting and other processes, involving more than 3000 connection points and thousands of processes, and the dimensional error accumulation effect in the manufacturing process is significant, resulting in the control of gap difference becoming an industry problem. Especially in sensitive areas of appearance (such as doors and side walls, hood covers and fenders), small deviations in gap difference will directly affect consumers' perception of vehicle quality, and even cause functional problems such as abnormal noise and sealing.

[0003] Currently, the body-in-white precision control mainly focuses on design optimization, manufacturing process control and detection technology. In the design stage, the structure of the stamping part is usually optimized, the matching of the assembly lap joint surface is matched, and strict geometric size and tolerance specifications are formulated to reduce theoretical error; In the manufacturing stage, measures such as improving the precision of single stamping, optimizing the welding sequence to reduce deformation, and using high-precision clamps are usually used to suppress error propagation; In the detection stage, three-coordinate measurement, laser scanning or automatic optical detection are usually used to realize rapid measurement and feedback of gap difference.

[0004] Although the above method can adjust the gap difference of the door and the side wall, the hood cover and the fender and other parts in the body-in-white manufacturing stage, so as to ensure the assembly effect of these parts, with the increasing emphasis on the streamlining of the design and the functional integration of the automobile, the assembly process of the automobile daytime running lamp has been delayed to the completion of the assembly stage, and at this time the body-in-white has been finalized, and its contour precision has been fixed. If the body-in-white cannot effectively control the precision of the daytime running lamp assembly position in the early manufacturing process, it may cause uneven gap and inconsistent gap between the daytime running lamp and other parts of the body-in-white in the assembly stage. These problems not only affect the appearance quality of the whole vehicle, but also may cause assembly difficulty, increase rework cost, and even affect the sealing and safety of the vehicle.
