The rotary table 3 is arranged between the two end plates 4, the driving mechanism is arranged on one side of one end plate 4 and connected with the rotary table 3, and the rotary table 3 is driven to rotate through the driving mechanism. Wherein, the side wall of carousel 3 sets up a plurality of draw-in groove 31 in succession, can drive a screw in each draw-in groove 31 and remove. The first guide edge 5 is fixed on the side wall of the end plate 4, and a first guide groove for guiding the screw to move is formed between the two first guide plates 5. When the screw is moved, the head part of the screw is limited by the clamping groove 31 and the first guide edge 6, the rod part of the screw is positioned in the first guide groove, and the screw is driven to move by the rotation of the turntable 3. The second guide edge 6 is arranged outside the first guide edge 5, a gap is formed between the first guide edge 5 and the second guide edge 6, and the gap is a channel for allowing the gasket to move; a second guide groove allowing the rod part of the screw to pass through is formed between the two second guide edges 6; the screw feeding groove 1 is fixed on the end plate 4 and is connected with the first guide groove, screws are fed into the rotary table 3 through the screw feeding groove 1, and the screws in the screw feeding groove 1 continuously move towards the gasket feeding mechanism 2 through continuous rotation of the rotary table; the gasket feeding mechanism 2 is arranged on one side of the rotary table 3; the rod part of the screw is used for taking out the gasket through the gasket feeding mechanism 2 and sleeving the gasket on the rod part of the screw, the rotary table 3 continues to rotate, the gasket falls into a channel between the first guide edge 5 and the second guide plate 6, and the gasket is borne on the second guide plate 6. When the screws reach the tail end of the first guide edge, the screws fall down and are jointly loaded on the second guide plate 6; one end of the second guide edge 6 is connected with the guide chute in an extending mode, and the assembled screws are sent into downward moving processing equipment.

In one embodiment, as shown in fig. 1-4, the driving mechanism includes a servo motor and a worm gear reducer, and the servo motor is connected with the turntable 3 through the worm gear reducer. The worm gear speed reducer changes the drive direction, can make equipment structure compacter.

In one embodiment, as shown in fig. 1 to 4, the gasket feeding mechanism 2 includes a material rail 21, a movable block 22, a pressing plate 23 and a blocking rod 24, the material rail 21 is disposed obliquely, and a trough 211 for guiding the gasket to move in an array is recessed on the upper surface of the material rail 21; through the structure, the gaskets can freely move downwards in the material groove 211 in an aligned mode. A gap is arranged at the end part of the material rail 21, and the movable block 22 is arranged in the gap and is rotationally connected with two side walls of the material rail 21; the pressing plate 23 is installed on the material rail 21 and positioned above the trough 211, and a channel for guiding and limiting the movement of the gasket is formed by the trough 211 and the pressing plate 23, and the gasket can only move one by one in the channel. Two blocking rods 24 are arranged, one end of each blocking rod 24 is arranged on the material rail 21, the other end of each blocking rod 24 is positioned at the outlet end of the material groove 211, and one ends of the two blocking rods 24, which are positioned at the material groove 211, are arranged at intervals, and the intervals allow the rod parts of screws to pass through; further, the stopper rod 24 and the movable block have a gap therebetween, which allows the spacer to pass therethrough. When the gasket feeding mechanism is used specifically, the turntable 3 drives the screw to do circular motion, when the screw reaches the gasket feeding mechanism 2, the rod part of the screw enters the gap between the two baffle rods 24 and is contacted with the inner ring of the gasket, and the end part of the rod part of the screw is just positioned in the inner ring of the gasket to reach the state shown in fig. 4; the screw continues to move, the upper side surface of the gasket is limited by the pressing plate 23 and is driven by the screw, the movable block 22 is rotated by the driving force to form a sufficient space for overturning the gasket, when the gasket is removed, the movable block 22 is reset, and the gasket at the front end moves to the end under the action of gravity and is blocked by the blocking rod 24; and completing the assembly of the screw and the gasket once. After the screw and the gasket are assembled, the gasket falls between the first guide edge 5 and the second guide edge 6, and the connection between the gasket and the screw is kept through the second guide edge 6; until the screw reaches the exit end of the first guide edge 5, the screw falls and is carried on the gasket.
