Description

Technical Field

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

[0002] Currently, the assembly of O-rings for smart toilet products 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, products and O-rings are prone to popping out during operation, resulting in material waste and loss. Furthermore, retrieving 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] In actual production, after O-rings are assembled, they need to be lubricated before they can be smoothly installed into products. Because lubricating oil is easy to contaminate and sticky, manual application creates a poor working environment, which discourages many operators from taking on this job, thus affecting product output. To improve this situation, it is essential to design an automatic O-ring lubrication device. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-4 :

[0021] An automatic oiling device for assembling an O-ring on the back cover of a smart toilet pressure regulator includes an oiling head 2 that is adapted to the insertion post of the back cover 1. The oiling head 2 completes the oiling operation when it is inserted into the insertion post of the back cover 1. An annular oil storage groove 3 is provided in the inner cavity of the oiling head 2. An axially sliding stripping sleeve 4 is provided on the outer sleeve of the oiling head 2. A stripping spring 6 is provided between the stripping sleeve 4 and the base 5 of the oiling head. The stripping spring 6 drives the stripping sleeve 4 to press tightly against the body of the back cover 1.

[0022] Furthermore, the oiling head 2 is driven to slide up and down by an oiling lifting cylinder, and the oiling lifting cylinder 9 is driven to slide horizontally by an oiling translation cylinder 10. Specifically, the oiling lifting cylinder 9 is fixed on a lifting cylinder mounting plate, and the lifting cylinder mounting plate is provided with a vertical guide rail for the oiling head base 5 to slide; the oiling translation cylinder 10 is fixed on a translation cylinder mounting plate, and the translation cylinder mounting plate is provided with a horizontal guide rail for the oiling lifting cylinder 9 to slide.

[0023] Furthermore, to improve the level of automation, the oiling head 2 is used in conjunction with the assembly positioning fixture 11 and the oiling workstation 12. The oiling head 2 moves back and forth between the assembly positioning fixture 11 and the oiling workstation 12 under the drive of the oiling translation cylinder 10. The assembly positioning fixture 11 is set on the turntable driven by the divider. The oiling workstation 12 includes an oil dipping head connected to the oiling system. The oil dipping head is provided with a circumferential oil outlet hole. When the oiling head 2 is fitted onto the oil dipping head, the oil dipping operation is completed.

[0024] The oiling process in this embodiment is as follows: the oiling lifting cylinder is driven by the oiling translation cylinder 10 to move to the oiling station 12, the oiling head 2 is driven by the oiling lifting cylinder 9 to move downward and fit onto the oil dipping head, the oiling station 12 delivers lubricating oil to the inner cavity of the oiling head 2 through the oil dipping head, and at the same time, a portion of the lubricating oil can be temporarily stored in the oil storage tank 3, and the oiling head 2 completes the oil dipping; the oiling lifting cylinder 9 is driven by the oiling translation cylinder 10 to move above the assembly positioning fixture 11, the oiling head 2 is driven by the oiling lifting cylinder 9 to move downward and fit onto the insertion post of the rear cover 1, the lubricating oil in the inner cavity of the oiling head 2 is evenly applied to the O-ring, and after the oiling is completed, the oiling mechanism is reset.

[0025] Furthermore, the stripping sleeve 4 is coaxially arranged with the oiling head 2 and has a clearance fit. The inner edge ring 7 at the upper end of the stripping sleeve 4 cooperates with the outer convex ring 8 of the oiling head 2 for limiting. By setting the limiting structure, the stripping sleeve 4 can be prevented from falling off the oiling head 2. Furthermore, the stripping spring 6 is sleeved on the oiling head 2. One end of the stripping spring 6 is in contact with the bottom of the oiling head base 5, and the other end is in contact with the upper end face of the stripping sleeve 4. Due to the action of the stripping spring 6, in the initial state, the inner edge ring 7 of the stripping sleeve 4 and the oiling head 2 are in contact with each other. When the oiling head 2 moves downward, the stripping sleeve 4 first contacts the body of the rear cover 1. Then the oiling head 2 continues to move downward and fits onto the insertion post of the rear cover 1. During this process, the stripping spring 6 is compressed. When the oiling is completed, the oiling head 2 moves upward. At this time, the stripping sleeve 4 is still in contact with the body of the rear cover 1 due to the action of the stripping spring 6, so that the rear cover 1 does not move upward with the oiling head 2. When the oiling head 2 disengages from the insertion post of the rear cover 1, the stripping sleeve 4 is driven by the limiting structure to leave the body of the rear cover 1 and reset.

[0026] To ensure precise positioning and prevent excessive movement of the equipment, a vertical travel limit structure 13 is provided on one side of the oiling head base 5; horizontal travel limit structures 14 are provided on the left and right sides of the oiling lifting cylinder; specifically, a vertical travel limit frame is provided on one side of the oiling head base 5, and a vertical travel buffer block is provided on the oiling head base 5 to cooperate with the limit; horizontal travel limit frames are provided on the left and right sides of the oiling lifting cylinder, and horizontal travel buffer blocks are provided on the horizontal travel limit frames to cooperate with the limit.

[0027] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
