Description

Technical Field

[0001] The invention belongs to the technical field of intelligent toilet assembly equipment, and relates to an assembly device for an O-ring of a rear cover of a pressure-stabilizing valve of an intelligent toilet. Background Art

[0002] Currently, the assembly of O-rings for smart toilets is largely manual. Because O-rings and assembly materials are generally small, installation requires either stretching the O-ring or partially wrapping it around the ring, holding it down with one hand, and then using another hand or a tool to pull it into place. Without fixtures or poorly made product positioning fixtures, the product or O-ring can easily pop out during the process, resulting in material waste and loss. Retrieving the material also wastes time, leading to low production efficiency.

[0003] To improve production efficiency, assembly using automatic assembly machines has become a trend. Chinese invention patent application CN107891272A (application date: April 10, 2018) discloses a toilet water inlet valve assembly production facility, comprising a station transmission track, a longitudinal assembly station, a transverse assembly station, and a feeding mechanism. The longitudinal assembly stations are spaced apart on the station transmission track and sequentially comprise a valve body station, a large O-ring assembly station, a piston body and anti-siphon rubber gasket assembly station, a water supply cap assembly station, a first small O-ring assembly station, a second small O-ring assembly station, and a filter assembly station. The transverse assembly station is located at the rear end of the longitudinal assembly station and comprises a water stop cap assembly station and a nut assembly station. The feeding mechanism is provided corresponding to the longitudinal and transverse assembly stations.

[0004] The aforementioned toilet water inlet valve assembly equipment only provides multiple automated assembly stations, which does not overcome the difficulties of existing O-ring assembly. Furthermore, after assembly, the O-ring still needs to be lubricated for smooth product installation. Because lubricant easily contaminates and sticks to hands, manual application creates a poor working environment and many workers are reluctant to perform this role, thus impacting product output. To improve this situation, fully automated O-ring assembly is imperative. Summary of the Invention
