[0043] like Figure 3 and Figure 4 As shown, in this embodiment, the conveying mechanism 500 includes a first guide member 510 and a first sliding member 520. The first guide member 510 is disposed between the second positioning mechanism 400 and each fixture magazine 600. The first sliding member 520 is mounted on the first guide member 510 and is capable of sliding along the guiding direction of the first guide member 510.

[0047] Preferably, in this embodiment, the first positioning mechanism 300 includes a support platform 310, on which a sensing component 312 is also installed. The sensing component 312 is fixed to the support platform 310 and is used to detect the positioning status of the automotive roof part. This facilitates the adjustment and determination of the position of the automotive roof part, improves its positional accuracy during production, and results in better quality of the automotive roof part.

[0048] Preferably, the sensing component 312 includes a support arm and a sensor located at the top of the support arm, wherein the sensor detects the positioning status of the vehicle roof part.

[0049] like Figure 1 and Figure 3As shown, in the embodiment, each second clamping device 200 comprises a plurality of clamps 210 for clamping the middle and the other end of each automobile roof part and a support plate 220 supporting the clamps 210; the first sliding member 520 is provided with a positioning pin 521 and the support plate 220 is provided with a pin seat 221, the positioning pin 521 is matched with the pin seat 221, so that the support plate 220 can be positioned on the first sliding member 520. The second clamping device 200 is fixed horizontally on the first sliding member 520, so as to avoid displacement of the second clamping device 200 during conveying.

[0050] Preferably, as Figure 5 With Figure 6 As shown, in the embodiment, the pin seat 221 comprises a main pin seat and a secondary pin seat, the main pin seat comprises a main body and four limiting wheels fixed on the main body and arranged in a cross shape, the limiting wheels guide and limit the pin rod of the positioning pin 521, when the pin rod is inserted into the pin seat 221, the limiting wheels guide the pin rod to the main body, the limiting wheels are arranged to prevent the pin rod from being stuck when inserted into the pin seat 221, and the cross-shaped limiting wheels enable the main pin seat to limit the positioning pin 521 in two directions in the horizontal plane; the secondary pin seat comprises a secondary body and two limiting wheels fixed on the main body and arranged in a straight line, and the secondary pin seat limits the pin rod in one direction.

[0051] Preferably, the main pin seat and the secondary pin seat are respectively located at the opposite corners of the support plate 220.

[0052] In other embodiments, the main pin seat can be arranged at the four corners of the support plate 220, so as to improve the positioning accuracy.

Since the limiting groove 621 is distributed along the guiding direction of the first guide member 510, when the second clamping device 200 needs to be transported from the positioning frame 420 to the fixture library 600, the support plate 220 moves away from the second positioning mechanism 400 along the guiding direction of the first guide member 510, and the second sliding member 620 extends out of the fixture library 600. Before the second clamping device 200 moves along the first guide member 510 to the corresponding fixture library 600, the traction wheel 223 can be engaged in the limiting groove 621 so that the support plate 220 is connected to the second sliding member 620, thereby enabling the second sliding member 620 to drive the support plate 220 to move into the fixture library 600. Similarly, when the second sliding member 620 moves the support plate 220 out of the fixture magazine 600, the second sliding member 620 moves the support plate 220 onto the first sliding member 520, and the first sliding member 520 can move the support plate 220 along the guiding direction of the first guide member 510 to the second positioning mechanism 400.

The plurality of first guide wheels 640 can reduce the resistance of the support plate 220 moving into / out of the fixture magazine 600, allowing the second guide member 610 to move the second clamping device 200 into / out of the fixture magazine 600 with less effort and greater direction.

[0058] like Figure 4As shown, in the embodiment, the first sliding member 520 is further provided with a plurality of second guide wheels 522, the plurality of second guide wheels 522 are distributed along the guiding direction of the second guide member 610, and the guiding direction of the second guide wheel 522 is the same as the guiding direction of the second guide member 610.
