The fixed bracket 8 is a cylindrical stainless steel frame, and a number of balls are installed in the top groove. The lower side of the rotating disk 14 presses on the balls, which can reduce the friction of the rotating disk 14 when it rotates. At the same time, through a number of counterweights on both sides, the rotation is more stable. The suction cup mounting frame 25 is a conical frame. After the push rod of the clamping block lifting electric cylinder 36 is fully extended, the lower surface of the suction cup mounting frame 25 is flush with the upper surface of the clamping block 37. After the suction cup 26 absorbs the parts, the clamping block 37 can be driven by the translation electric cylinder 30 to approach the parts from the front and back sides and clamp them. Finally, the electric push rod of the clamping electric cylinder 38 is controlled to extend to press the parts from the upper side to prevent the parts from tilting or falling after the failure of some suction cups 26. After absorbing the parts, the main screw motor 4 and the main rotating motor 12 can be controlled to move and rotate the whole to the stacking position, and then the parts can be put down and stacked. ;

[0022] The working principle of the present invention is as follows: when in use, the whole is moved to the right side of the parts to be stacked and fixed, and then the suction cup suction position is selected according to the surface conditions of the parts, and the suction cup rotating motor 28 is controlled to rotate, and the suction cup rotating shaft 23 is driven to rotate to a suitable position through the transmission gear set 29, and then the suction cup rotating motor 28 is controlled to stop. Then the lifting electric rod 21 is controlled to descend, and the electric push rod approaches the parts to be stacked from above until the suction cup 26 is completely in contact with the upper surface of the parts. At this time, the lifting electric rod 21 is controlled to stop, and the vacuum generator 27 is started to suck up the parts, and at the same time, the electric push rod of the clamping block lifting electric cylinder 36 is controlled to extend. After the electric push rod of the clamping block lifting electric cylinder 36 is fully extended, the electric push rod of the translation electric cylinder 30 is controlled to be retracted, and the connecting plate 31 is driven to move toward the center to clamp the parts from the front and rear sides. Finally, the electric push rod of the clamping electric cylinder 38 is controlled to extend, and the parts are pressed from the upper side, and subsequent movement can be performed.

[0023] After the parts are sucked and clamped, the electric push rod of the lifting electric cylinder 21 can be controlled to be completely retracted, driving the mounting frame 22 to rise as a whole, and raising the parts to the highest position. Then, according to the position where the parts need to be stacked, the main screw motor 4 is controlled to rotate, driving the main screw 3 to rotate, and then driving the whole to move to the stacking position. At the same time, the rotation motor 12 is controlled to rotate, and the gear 11 is driven to rotate through the driving gear 13, and then the rotating disk 14 is driven to rotate above the part stacking position and then stop. Finally, the electric push rod of the lifting electric cylinder 21 can be controlled to extend until the parts are placed in the specified position, and then the vacuum generator 27 is controlled to be closed, and the electric push rod of the clamping electric cylinder 38 is retracted, and the electric push rod of the translation electric cylinder 30 is extended to make the clamping block 37 away from the parts. The above operation can be repeated to clamp and stack new parts. Before clamping the parts again, according to the edge of the parts, the clamping screw motor 34 can be controlled to rotate, driving the clamping screw 33 to rotate, adjusting the position of the clamping screw slider 35, and then adjusting the position of the clamping block 37, so as to avoid the position where the edge of the parts is not suitable for clamping.
