[0002] Automotive sheet metal generally refers to the metal sheets used to manufacture automobile bodies and parts.

[0015] Working principle: When the manipulator is needed, different types of splints are selected according to the different materials of the metal plates. The push piece is pushed to drive the push rod to slide, and the second spring is squeezed during the sliding process. The sliding of the push rod will drive the fixed piece to slide and push the clamping column. The clamping column will simultaneously push the sliding piece to slide and squeeze the first spring. When the clamping column is completely retracted into the interior of the fixed column, the splint and the fixed column can be removed from the connecting plate and replaced. The easy-to-replace design allows different types of splints to be replaced to suit metal plates of different materials, thereby improving versatility and stability. The distance between the splints is adjusted according to the different sizes of metal plates. The motor is started to drive the threaded column to rotate. The threaded column drives the slider to slide through the first limit block. When the slider slides, it drives the rotating rod to rotate through the first rotating shaft. The rotation of the rotating rod drives the pulling block to slide through the second limit block through the second rotating shaft. The sliding of the pulling block drives the connecting plate and the splint to slide at the same time, clamping and fixing the metal plates, so as to achieve the effect of being suitable for metal plates of different sizes and clamping and fixing them, thereby ensuring stability during transportation; After the metal plate is clamped, the cylinder is started to push the rack to slide through the limit bar. When the rack slides, it will drive the gear and the connecting shaft to rotate. When the connecting shaft rotates, it will drive the second robotic arm to rotate. The second robotic arm will drive the first robotic arm to slide through the support block through the fixed shaft, and make the support block slide through the limit plate. The connecting plate and the fixed plate are driven to move by the first robotic arm, thereby transferring and transporting the position of the automobile metal plate, achieving the effect of automated transportation of the metal plate and improving transportation efficiency.

[0016] The present invention provides a metal plate transport robot for automobiles. It has the following beneficial effects: 1.

Then, the clamping device is adjusted to select different types of clamping plates 13 according to different metal plate materials. By pushing the push piece 20 to slide, the push piece 20 will drive the push rod 19 to slide during the sliding process. At the same time, the push piece 20 will squeeze the second spring 21 during the sliding process. When the push rod 19 slides inside the connecting plate 12, it will drive the fixed piece 22 to slide inside the connecting plate 12. During the sliding process, the fixed piece 22 will push the card column 16 to slide inside the connecting plate 12 and the fixed column 15 at the same time. The sliding of the card column 16 will synchronously push the slide 17 to slide. During the sliding process of the slide 17, the first spring 18 is squeezed.
