A plurality of support legs 170 are fixedly arranged on the first baffle and the second baffle, respectively.

[0052] A method for conveying metal sheets, using the above-mentioned conveying device for metal sheets, comprises the following steps:

[0053] S1, when the work starts, the position of the second connecting frame 160 is moved as needed, and the size of the angle formed between the first connecting frame 150 and the second connecting frame 160 is changed. The conveying device for metal sheets can be adjusted according to different working environments and requirements to adapt to different production conditions. It has strong adaptability, small footprint, and flexible layout at any position. This flexibility allows the production line to be quickly adjusted to meet different production needs, thereby greatly improving the production efficiency of the production line. Multiple conveying directions can be realized on the same conveying device for metal sheets, so the demand for other conveying equipment can be reduced, thereby reducing the equipment investment cost.

[0054] S2, when the angles of the first connecting frame 150 and the second connecting frame 160 change, the second connecting plate 120 moves closer to or farther from the supporting frame 100. Under the action of the first spring 202, the first telescopic rod 200 extends or shortens, and under the action of the first telescopic rod 200 and the second spring, the limiting rod 140 always abuts against the first connecting plate 110 or the limiting telescopic rod 130.

[0055] S3, start the two first motors, the first motor drives the plurality of rollers 300 to rotate through the first transmission belt, start the second motor on the first connecting frame 150, the second motor drives the plurality of first telescopic rods 200 to rotate through the second transmission belt, and the first telescopic rods 200 rotate and drive the plurality of rotating wheels 210 to rotate.

[0056] S4, when one corner of the metal plate 500 abuts against the second connecting plate 120, the rotating wheel 210 on the first connecting frame 150 continues to rotate, providing a rotational force to the metal plate 500, so that the metal plate 500 rotates. When the side of the metal plate 500 is attached to the second connecting plate 120 and the two contact points are detected by the sensor 400, the second motor on the second connecting frame 160 is started by the controller, and the second motor drives the rotating wheel 210 on the second connecting frame 160 to rotate, and the rotating wheel 210 on the second connecting frame 160 drives the metal plate 500 to move from the first side to the second side of the support frame 100. After the metal plate 500 leaves the second connecting plate 120, the controller turns off the second motor on the second connecting frame 160.

[0057] Afterwards, the metal plate 500 is always close to the fourth side of the support frame 100, thereby ensuring the accuracy of transportation, allowing each link on the production line to be connected more smoothly, and avoiding production bottlenecks or delays caused by inconsistent positions of the metal plate 500. During the transportation process, if the position of the metal plate 500 is unstable, it may be subjected to additional stress or impact, resulting in deformation or damage. Maintaining a consistent position can effectively avoid this situation. Since the metal plates 500 with consistent positions are easier to process and handle, the waste of materials caused by improper processing or improper handling can be reduced, and it is more convenient for the subsequent collection of the metal plates 500.
