Description

Technical Field

[0001] This utility model belongs to the technical field of intelligent toilet assembly equipment, and relates to an automatic feeding device for the back cover of an intelligent toilet pressure regulating valve. Background Technology

[0002] Currently, the assembly of O-rings for the back cover of smart toilet pressure regulators is primarily done manually. Because O-rings and assembly materials are generally small, installation requires opening or partially covering the O-ring, holding it down with one hand, and then using the other hand or a tool to pull it into place. Without proper tooling or fixtures, or with poorly made tooling, the product and O-ring are prone to popping out, resulting in material waste and loss. Furthermore, picking up the materials wastes time, leading to very low production efficiency.

[0003] To improve production efficiency, assembly using automated assembly machines has become a trend. Chinese utility model patent application CN107891272A (application date: 2018-04-10) discloses a toilet inlet valve assembly production equipment, which includes a workstation transport track, longitudinal component assembly stations, transverse component assembly stations, and a feeding mechanism. The longitudinal component assembly stations are spaced apart on the workstation transport track, and sequentially include a valve body station, a large O-ring assembly station, a piston body and anti-siphon gasket assembly station, a water inlet cap assembly station, a first small O-ring assembly station, a second small O-ring assembly station, and a filter assembly station. The transverse component assembly stations are located at the rear end of the longitudinal component assembly stations, and include a water stop cap assembly station and a nut assembly station. The feeding mechanism is correspondingly arranged with the longitudinal and transverse component assembly stations.

[0004] While the aforementioned toilet inlet valve assembly equipment can automatically assemble O-rings, its feeding mechanism lacks optimized design, hindering accurate positioning of assembly components and thus affecting O-ring assembly. Therefore, it is essential to develop an automatic feeding device for the toilet pressure regulator valve cover, enabling rapid and accurate feeding to facilitate O-ring assembly.

[0015] This invention provides an automatic feeding device for the back cover of an intelligent toilet pressure regulator. It employs a contour-following positioning fixture to achieve precise positioning of the back cover. The pneumatic grippers for the back cover utilize a double V-block distance-fixing mechanism, ensuring precise gripping of the back cover while effectively preventing excessive movement of the grippers, thus better protecting the back cover. This invention can accurately position and feed the back cover into the assembly positioning fixture of the assembly machine, facilitating subsequent O-ring assembly. It offers the advantages of fast feeding and accurate positioning. Attached Figure Description
