[0063] 6. The present invention drives the second bidirectional screw to rotate via a third motor. The second bidirectional screw drives two second transverse moving plates to move towards each other. The two second transverse moving plates move towards each other via corresponding columns. After moving the two short-side pushing plates to the required position, the two transverse moving plates are stopped. The second transverse moving plates are limited to move along the second slide rail via a third slider.

[0064] 7. The present invention rotates the first lower pressure plate to above the short side placement plate by means of the actuator of the first corner clamping cylinder, and then drives the first lower pressure plate to move downward by means of the actuator of the first corner clamping cylinder. The first lower pressure plate abuts against the upper surface of the short side material contained on the short side placement plate, thereby fixing the short side material on the short side placement plate. This solves the technical problem of how to fix the short side material placed on the short side placement plate.

[0065] 8. The present invention rotates the second lower pressure plate to above the long side placement plate by means of the actuator of the second corner clamping cylinder, and then drives the second lower pressure plate to move downward by means of the actuator of the second corner clamping cylinder. The second lower pressure plate abuts against the upper surface of the long side material contained on the long side placement plate, thereby fixing the long side material on the short side placement plate. This solves the technical problem of how to fix the long side material placed on the long side placement plate.

[0066] 9. The present invention uses a rubber pad adhered to the bottom surface of the first lower pressure plate to abut against the upper surface of the short side material, and a rubber pad adhered to the bottom surface of the second lower pressure plate to abut against the upper surface of the long side material, thereby increasing the contact area and further increasing the fixation, thus solving the technical problem of how to further fix the short side material on the short side placement plate and the long side material on the long side placement plate.

Furthermore, the connecting piece 4 on the short side material 2 can be quickly inserted into the long side material 3, thereby improving assembly efficiency during production.

[0098] S2: The grid plate 1 is straightened by the straightening device 8, and the two short sides of the grid plate 1 are fixed.

[0099] S3: Place the two long edge members 3 sequentially on the two long edges of the grating plate 1 by means of a robotic arm or manually;

[0100] S4: The two long side materials 3 are pre-connected to the two long sides of the grating plate 1 by the long side pushing device 9;

[0101] S5: The short side material 2 is placed sequentially on the two short sides of the grating plate 1 by the robotic arm;

[0102] S6: The two short side materials 2 are simultaneously pushed to the two short sides of the grid plate 1 by the short side pushing device 10, so that the two ends of the two short side materials 2 are respectively engaged with the two ends of the two long side materials 3.

[0103] S7: The two short side members 2 and the two long side members 3 are tightened at their respective close ends by the screw-on robot arm, thereby forming the return air grille.

[0111] Based on the above embodiments, the technical problem this application aims to solve is how to automatically assemble automotive return air grilles. To this end, this application achieves automatic assembly of automotive return air grilles through the interaction of a workbench 7, a straightening device 8, a long-side pushing device 9, and a short-side pushing device 10. Specifically, a robotic arm places the grille plate 1 to be assembled horizontally on the support surface of the workbench 7. Two opposing plates within the straightening device 8 move towards each other, simultaneously driving two centering clamps 12 to move towards each other. The two centering clamps 12 pre-position and center the two short sides of the grille plate 1. The robotic arm then sequentially places the long side to be assembled onto two long-side placement plates 18, and the two second opposing plates 16 within the long-side pushing device 9 further facilitate this assembly.
