The threaded sleeve 508 cooperates with the translation screw 7 to drive the translation support plate 501 to slide back and forth on the translation bracket 1. The contraction bracket 507 is a parallelogram with four support rods connected end to end and hinged. One group of diagonals of the contraction bracket 507 is respectively connected to the two contraction support plates 502 through a pull rod 509, and the other group of diagonals is respectively connected to the piston rods of the two contraction cylinders 506. The middle parts of the two support rods adjacent to the contraction support plate 502 are rotatably connected to the translation support plate 501.

[0020] The retractable bracket 507 can make the two retractable support plates 502 move synchronously toward and away from the translation support plate 501 under the drive of the retractable cylinder 506, thereby ensuring that both ends of the workpiece are effectively clamped when grabbing it to avoid falling off during transportation.

[0021] A stopper 503 is installed at the lower end of the retractable support plate 502, and a clamping cylinder 505 and a clamping block 504 are arranged on the retractable support plate 502 above the stopper 503.

When grabbing a workpiece, the two retractable support plates 502 approach each other to clamp the workpiece in the horizontal direction, and the stopper 503 cooperates with the clamping block 504 to clamp the workpiece in the vertical direction, which further improves the stability of grabbing the workpiece. At the same time, the setting of the stopper 503 and the clamping block 504 is more suitable for grabbing workpieces with plates or flanges.

[0022] Reference Figure 3 The flipping mechanism 6 includes two flipping support plates 601, on which a rotating shaft 602 is arranged, which is rotatably mounted on the flipping bracket 2 and connected to the output shaft of the flipping motor 8, and two symmetrical flipping pads 603 are installed between the two flipping support plates 601, and a grabbing cylinder 604 and a slide rail 605 are arranged on the adjacent surfaces of the two flipping pads 603, and the piston rod of the grabbing cylinder 604 is connected to the slider of the slide rail 605, and an L-shaped clamping plate 607 is arranged on the flipping pad 603, and the middle part of the L-shaped clamping plate 607 is rotatably connected to the flipping pad 603, and its horizontal end is on the outer side of the flipping pad 603, and a connecting rod 606 is installed between the vertical end and the slider of the slide rail 605, and the two ends of the connecting rod 606 are respectively hinged to the L-shaped clamping plate 607 and the slider of the slide rail 605.

[0023] A lifting hole 608 is arranged on the flip pad 603, and a lifting mechanism is arranged between the grabbing cylinder 604 and the slide rail 605. The lifting mechanism includes a lifting plate 610 arranged on the outer side of the flip pad 603. Two lifting support plates 609 are hinged at the bottom of the lifting plate 610, and the other ends of the two lifting support plates 609 are respectively hinged to the slider of the slide rail 605 and the side wall of the lifting hole 608.

[0024] When picking up the workpiece, the workpiece is lifted by the feed conveyor belt 3 through the lifting mechanism 4, the piston rod of the grabbing cylinder 604 on the adjacent side of the feed conveyor belt 3 is extended, and the horizontal end of the L-shaped clamping plate 607 is flipped toward the outside of the flip pad 603 and engages with the edge of the workpiece. At the same time, the lifting plate 610 approaches the flip pad 603, thereby clamping and fixing the workpiece, and the flip motor 8 drives the workpiece to rotate 180° to the bottom of the clamping mechanism 5.

[0025] During transfer, the piston rod of the grabbing cylinder 604 retracts, and the horizontal end of the L-shaped clamping plate 607 disengages from the workpiece. At the same time, the lifting plate 610 rises driven by the two lifting support plates 609, thereby lifting the workpiece to facilitate the gripping of the clamping mechanism 5.
