In some embodiments, referring to fig. 9 (c) and 10 (c), there are two spacing pins 616, with two spacing pins 616 being disposed side-by-side. When the first clamp 617 drives the first pressing block 6171 to move along the direction close to the placement surface 6141 of the first placement portion 614, the first pressing block 6171 is located between the two limiting pins 616.

In some embodiments, referring to fig. 10 (a), the support surface 6151 is an L-like shaped surface, and the transverse segment and the vertical segment of the support surface 6151 are smoothly transitioned through an arc surface. To better conform to the curvature of the door hinge 10.

Example 1:

The white car body is transmitted to the first station 2 through the white car body conveying line 1, the first robot 2 measures a plurality of preset measuring points on the white car body through vision measuring equipment, after measurement data are obtained, a plane fluctuation value and a correction amount are calculated, if a PLC controller is arranged on each station, the correction amount is transmitted to the PLC controller, and if the PLC controller is not arranged on each station, the correction amount can be directly transmitted to a component for controlling the motor linear module 612. The door hinge 10 is Z-shifted by the motor linear module 612.

The first robot 2 automatically takes materials from the NT door material box 4, and then puts the materials on the door hinge positioning tool 6 of the second station 5, and the NT door 11 is clamped by the clamping mechanism 63 of the door hinge positioning tool 6. Meanwhile, the door hinge 10 of the second station 5 is manually fed and placed to the correcting mechanism 61 for positioning. The process of performing the Z-directional positional shift on the door hinge 10 by the motor linear module 612 may be performed before or after the door hinge 10 is fed. After the deflection, the bolt tightening mechanism on the second robot 7 is used for tightening the bolt of the door hinge 10, so that the door hinge 10 and the NT door 11 are installed.

The third robot 8 is used for carrying the NT door assembly with the door hinge 10 mounted to the body-in-white on the body-in-white conveying line 1, and before the NT door assembly is mounted with the body-in-white, the NT door assembly and the body-in-white are positioned by a vision guiding mechanism of the third robot 8, so that the mounting position of the NT door meets the final size matching requirement.

After the NT door assembly and the white body are positioned, the bolt tightening mechanism on the handle of the fourth robot 9 is used for tightening the bolt of the door hinge 10, so that the installation between the door hinge 10 and the white body is realized, and finally, the automatic installation between the NT door and the white body is realized.

After the installation is completed, the third robot 8 measures the important matching surface again by a self-contained visual guiding mechanism and uploads the data. The measurement is the same as the first measurement element, and only the gap surface difference of the NT door 11 after the bolt is beaten is retested.
