[0029] The working principle of this utility model: The dual-cylinder screw loading and transfer mechanism is an automated loading and operation device, mainly used for the automatic arrangement, operation, and loading of screws in industrial production. Its core is the high-precision, high-cycle screw positioning, gripping, and loading achieved through the coordinated movement of two electric cylinders. Its main mechanical structure and working principle are as follows: A vibratory feeder starts, sorting and conveying the bulk screws 1 to the screw handling mechanism 2 of this utility model embodiment. The screws 1 are then arranged in an orderly manner on the threaded sliding block 211 of the screw handling mechanism 2, where the threaded sliding block 211 receives the screws. Simultaneously, the upper cylinder pressure plate 212 transmits the power of the small cylinder 213 to the threaded sliding block 211, realizing the clamping and loosening operation of the screws 1. During this process, after the photoelectric sensor 214 detects that the screw 1 has arrived, it triggers the dual electric cylinders; the first electric cylinder 9 and the second electric cylinder 10 operate to transfer the screws. During the handover process, firstly, the threaded sliding block 211 on the screw handling mechanism 2, under the action of the pneumatic slide table 215, will retract the screw 1 to the designated position to avoid interference with the vibratory feeder during subsequent rotation operations, thus protecting the screw's operation. Then, the handling table cylinder 216 will drive the rotary cylinder connecting plate 217 to rotate, causing the screw 1 vertically clamped on the threaded moving block 211 to move. When it rotates to 90 degrees, i.e., the screw 1 is in a horizontal position, the drive stops, and it moves forward under the action of the handling mechanism drag chain 3 and the left linear slide rail 4. Under the action of the rectangular protective sheet metal 5, it reaches the designated position. The screw is then handed over to the screw loading mechanism 6 coming from the opposite side. The screw loading mechanism 6 performs a reciprocating handover motion under the action of the loading mechanism drag chain 7 and the right linear slide rail 8. The screw feeding mechanism 6 is driven by the feeding swing cylinder 611 to rotate the flipping pad 612, causing the front mechanical gripper 613 to flip to a horizontal position on the right to receive the screw 1 from the screw handling mechanism 2. During the return stroke, the front mechanical gripper 613 flips to a horizontal position on the left to feed the screw 1. Due to variations in the size and length of the screw 1, a push-pull module servo motor 20 is added to the left side of the screw feeding mechanism 6. Driven by the push-pull module servo motor 20, the screw feeding mechanism 6 connected to the upper plate 614 of the push-pull module is adjusted in position, allowing the mechanical gripper 613 to accurately grasp screws of different sizes. In summary, this completes the high-speed screw handling operation with dual electric cylinders.
