7. The intelligent ordered bolt and nut matching device as claimed in claim 1, wherein the bottom of the placing cavity is of an open structure, and an end cover assembly is arranged at the bottom of the placing cavity;
the end cap assembly includes: the device comprises a material guide pipe extending downwards, supports fixed on the outer surface of the material guide pipe at equal intervals, sliding grooves formed in the bottom surface of each support, connecting pins clamped in the sliding grooves in a movable mode, petal blades fixed on each connecting pin, a rotating part connected to each connecting pin in a transmission mode, an outer gear ring fixed on the outer edge of each rotating part, a rotating motor fixed on a placing frame and a rotating gear connected to the output shaft of the rotating motor in a transmission mode;
the rotating gear is meshed with the outer gear ring; one side of the connecting pin and one side of the petal blades are simultaneously subjected to limiting transmission of the sliding groove and the rotating piece, and the rotating piece rotates under the transmission of the rotating gear and the outer gear ring to drive the sliding groove and the rotating piece to move inside and outside the sliding groove, so that the closed state and the open state of the petal blades are realized.
8. The matching method using the intelligent ordered bolt and nut matching device as claimed in any one of claims 1 to 7, is characterized by comprising the following steps:
firstly, respectively pouring a bolt, a nut, a spring gasket and a flat gasket into a bolt feeding mechanism, a nut feeding mechanism, a first ingredient feeding mechanism and a second ingredient feeding mechanism;
secondly, the bolts are orderly arranged to an outlet through a first vibrating disc by a bolt feeding mechanism, the bolts in front are pushed into the aisle assembly under the pushing of the bolts behind, the screw rods of the bolts fall down from the two guide strips under the action of the two parallel guide strips, so that the heads of the bolts are hung on the two guide strips, the bolts in transverse arrangement are longitudinally arranged, the heads of the bolts are positioned at the top ends, the bolts in front are continuously pushed and reach the guide parts after passing through the reversing parts, the heads of the bolts are positioned at the bottom ends at the moment, the supports of the supporting parts are lost when the bolts move to the tail ends of the guide parts, the bolts positioned at the tail ends directly fall into the placing cavity, and the petal blades at the bottom of the placing cavity are in a closed state;
thirdly, under the action of the rotating mechanism, the placing cavity where the bolt is placed is transferred to the first batching feeding mechanism and the second batching feeding mechanism, and the spring gasket and the flat gasket are matched on the bolt;
transferring the bolt matched with the spring gasket and the flat gasket to a nut feeding mechanism under the action of a rotating mechanism, clamping and transferring the bolt positioned at the outlet of the second vibrating disk to the bolt by a clamping jaw assembly in the nut feeding mechanism, and screwing the nut on the bolt by combining a rotating motor and a Z-axis moving assembly;
fifthly, after the bolt is screwed into the clamping jaw assembly by 1-2 cm, a clamping plate in the clamping jaw assembly has no acting force on the nut, an ejector rod ejects an ejector block to be in contact with the top end of a screw rod of the bolt, and then the clamping jaw assembly moves upwards under the action of a Z-axis moving assembly to prepare for clamping a next nut;
and step six, the bolt screwed with the nut leaves the nut feeding mechanism, the petal blades at the bottom of the placing cavity are in an open state, and the bolt is discharged.
