Description

Technical Field

[0001] The utility model relates to the technical field of pacifier assembly, in particular to an automatic assembly jig for a pacifier and a supporting bottle cap. Background Art

[0002] Due to the design and structural characteristics of the baby bottle product, in order to prevent the nipple from falling off when the bottle cap is opened, the assembly relationship between the rubber nipple and the bottle cap is usually designed as a deep groove with a waist at the bottom of the nipple rubber part. During assembly, the rubber part is deformed to embed it into the step at the bottle cap mouth. Since the rubber nipple needs to be squeezed to produce a large deformation before it can be installed in the step of the bottle cap, the assembly process is completed manually on the assembly line.

[0003] Chinese patent CN116900686A discloses a nipple assembly device for producing feeding bottles, comprising a machine body, an assembly mechanism and a fitting mechanism. The machine body is provided with a conveying mechanism for conveying the nipple and the screw cap respectively. The assembly mechanism comprises a mounting ring mounted on the machine body, and two groups of arc blocks are fixedly connected to the side of the mounting ring. The assembly mechanism is used to drive the mounting ring to move upward so that the top surface of the arc block contacts the bottom surface of the sealing ring, thereby pushing the sealing ring at the bottom of the nipple to move upward and dock with the screw cap on the upper side. The fitting mechanism comprises a first roller mounted on the mounting ring. The fitting mechanism is used to push the first roller toward the inner wall of the sealing ring after the mounting ring is lifted to a set position, and drive the mounting ring to rotate, so that the first roller pushes the sealing ring to fit tightly with the annular groove on the screw cap, and when the mounting ring moves downward, the first roller is preferentially released from the conflict with the sealing ring to avoid pulling the installed nipple downward.

[0004] However, when the device is installed on a pacifier with a deep waist groove, the deep waist groove on the pacifier prevents the pacifier from falling. When the pacifier is directly driven to move upward to dock with the screw cap, the pacifier will be squeezed, which may cause scratches on the pacifier or damage the pacifier.

[0005] Based on this, the utility model designs an automatic assembly jig for a pacifier and a supporting bottle cap to solve the above problems. Utility Model Content
