The bottle cap locking mechanism 6 also includes a first horizontal sliding plate 20, a first horizontal driving device 21, a second lifting slider and a second lifting driving device. The first horizontal sliding plate 20 can be installed on the frame 1 to slide in the horizontal direction. The first lifting slider 14 can be installed on the first horizontal sliding plate 20 to slide and lift in the longitudinal direction. The first horizontal driving device 21 drives the first horizontal sliding plate 20 to slide back and forth so that the upper cover positioning device 11 alternately faces the positioning hole of the upper cover 19 and the positioning hole of the lower cover 18.

When the torque detection device 23 detects that the torque of the upper cover 19 and the lower cover 18 reaches a preset value, the rotation drive device 16 stops driving the upper cover 19 to rotate, achieving accurate locking of the upper cover 19 and the lower cover 18.

Each first material receiving suction nozzle 24 It can just be aligned with the positioning hole of the lower cover 18 on the carrier plate 17 at the third designated position, and several first negative pressure providing devices 27 can provide negative pressure to each first material receiving suction nozzle 24. The third lifting drive device 28 drives the third lifting slider 25 to move up and down, and the second horizontal drive device 29 drives the second horizontal sliding plate 26 to slide horizontally so that the first material receiving suction nozzle 24 is aligned with the positioning hole of the lower cover 18 on the carrier plate 17 or with the opening of the qualified product accommodating device. The control system controls the operation of the third lifting drive device 28, the second horizontal drive device 29 and each first negative pressure providing device 27.

[0031] When receiving materials, the control system determines whether the torque of the finished bottle caps is qualified according to the detection information of the torque detection device 23. After the finished bottle caps are transported to the third designated position with the carrier plate 17, the third lifting slide block 25 descends, so that the first material receiving suction nozzle 24 contacts the bottle caps on the carrier plate 17. The control system controls the first negative pressure providing device 27 facing the bottle caps with qualified torque to start, and the first material receiving suction nozzle 24 sucks the qualified bottle caps on the carrier plate 17. The third lifting slide block 25 rises and resets, and the second horizontal driving device 29 drives the second horizontal sliding plate 26 to slide horizontally, and moves the qualified bottle caps to the top of the finished product accommodating device. After the first negative pressure providing device 27 stops providing negative pressure, the qualified bottle caps fall into the finished product accommodating device for storage.

At the same time, the fourth horizontal sliding plate 43 slides horizontally to send the lower covers 18 and the upper covers 19 to the first designated position and the second designated position on the carrier plate 17 for positioning, so that the conveying mechanism 9 can convey them to the locking mechanism for locking. This structure can realize multiple products at one time. The loading is efficient and manual loading is avoided. A dislocation device can also be set at the end of the discharge channel 38. A push rod can push and block the last one, two or more upper covers and lower covers to change lanes, so that they are dislocated with the other upper covers and lower covers in the discharge channel, and then the suction nozzle can suck them up to avoid the upper and lower covers being crowded in the discharge channel and causing position accuracy errors, ensuring the loading position is accurate and ensuring that the suction nozzle can suck them up smoothly. In addition to adopting this loading structure, it can also be a multi-axis manipulator for automatic loading, or The upper cover 19 and the lower cover 18 are placed in order in the longitudinally extended upper cover silo 3 and the lower cover silo 2 respectively, and a gap that can only accommodate one product is set at the lower end of the upper cover silo 3 and the lower cover silo 2. The product is pushed to the first designated position and the second designated position by a push plate, or the products are output in an orderly manner in a row through a vibration plate, and the adjacent products are displaced by a dislocation mechanism to achieve the output of adjacent products to the carrier plate 17 at intervals. These are equivalent replacement structures that can be easily thought of by those skilled in the art based on this patent.

[0034] The transport mechanism 9 includes a turntable 47 and a turntable drive 48 that can be rotatably mounted on the frame 1. A plurality of carriers 17 are fixedly mounted on the turntable 47 at even intervals. The lower cover automatic loading mechanism 4, the upper cover automatic loading mechanism 5, the bottle cap locking mechanism 6, the automatic material receiving mechanism 7, and the defective product receiving mechanism 30 are evenly spaced and distributed outside the circumference of the turntable 47. The turntable drive 48 drives the turntable 47 to rotate intermittently, and the control system controls the start and stop of the turntable drive 48. By mounting the carriers 17 on the turntable 47, the turntable 47 carries the carriers 17 for intermittent transport along the circumference, thereby realizing the transport of products. This structure is simple and has high transport efficiency. It can realize the automatic circulation of the carriers 17, save the carriers 17 and transfer space, and occupy a small space in the factory. In addition, the various mechanisms can be arranged in a straight line, and the transport mechanism 9 can be an intermittent conveying conveyor belt, or a pushing mechanism, or a pulling mechanism, or a robot, etc.

[0035] The defective product receiving mechanism 30 also includes a carrier plate material presence sensing device 49. The carrier plate material presence sensing device 49 can sense the lower cap 18 in any lower cap 18 positioning hole and the upper cap 19 in any upper cap 19 positioning hole on the carrier plate 17 and transmit a signal to the control system. The material presence sensing device senses the bottle caps on the carrier plate 17 passing through the receiving material. If it senses that there are any remaining bottle caps, the defective product receiving mechanism 30 will operate again to suck away the remaining bottle caps, thereby preventing the remaining bottle caps on the carrier plate 17 from causing the next feeding cycle to fail due to the remaining bottle caps on the carrier plate 17. The material presence sensing device can be a light that can be installed on the frame 1 and can be raised and lowered. It can sense the bottle caps extending to the lower side of the carrier plate 17 by irradiating the light. The light rises to sense and detect the bottle caps on the carrier plate 17. After the detection is completed, the light falls to avoid interference with the movement of the carrier plate 17 with the turntable 47.
