Description

Technical Field

[0001] This utility model belongs to the technical field of intelligent toilet assembly equipment, and relates to an automatic oil supply device for O-ring assembly. 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 the O-rings are assembled, they need to be coated with oil before they can be successfully installed into the product. 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, an automatic oiling mechanism needs to be installed on the O-ring assembly machine, and the automatic oil supply device is an important part of this. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-5 :

[0023] An automatic oil supply device for O-ring assembly includes an oil tank 1, an oil supply valve 2, and an oil dipping platform 3. The oil tank 1 is connected to the oil supply valve 2 via a first one-way valve 4, and the oil supply valve 2 is connected to the oil dipping platform 3 via a second one-way valve 5. The oil tank 1 is equipped with an oil-pressing cylinder 6 that delivers lubricating oil to the oil supply valve 2, and the oil supply valve 2 is equipped with an oil supply cylinder 7 that delivers lubricating oil to the oil dipping platform 3. Both the oil-pressing cylinder 6 and the oil supply cylinder 7 are controlled by a pneumatic controller 8. The oil dipping platform 3 is equipped with an oil dipping head 9, and the oil dipping head 9 is equipped with multiple oil outlets 10 evenly distributed circumferentially.

[0024] The oil supply process in this embodiment is as follows: The lubricating oil in the oil drum 1 is driven by the oil pressure cylinder 6 (the oil pressure cylinder 6 drives the oil pressure piston to move downward to compress the inner cavity of the oil drum 1, and the lubricating oil in the oil drum 1 is then output from the oil drum 1), and enters the cavity of the oil supply valve 2 through the first one-way valve 4. The lubricating oil in the cavity of the oil supply valve 2 is then driven by the oil supply cylinder 7 (the oil supply cylinder 7 drives the oil supply piston to move upward to compress the inner cavity of the oil supply valve 2, and the lubricating oil in the oil supply valve 2 is then output from the oil supply valve). 2) The oil enters the oiling station 3 through the second one-way valve 5 and is discharged from the oil outlet 10 through the oil delivery channel. In this embodiment, it is used in conjunction with the oiling head. The inner cavity of the oiling head is adapted to the O-ring's fitting structure. For example, when assembling the O-ring on the back cover of the pressure regulator valve, the inner cavity of the oiling head can be fitted onto the back cover's insertion post. When dipping oil, the inner cavity of the oiling head is fitted onto the matching oiling head 9, and the lubricating oil discharged from the oil outlet 10 is input into the inner cavity of the oiling head to complete the dipping.

[0025] In this embodiment, in order to simplify the structure, the first check valve 4 and the second check valve 5 are both disposed on the interface of the oil supply valve 2, and the structure of the first check valve 4 and the second check valve 5 adopts a common structure in the art.

[0026] Below the aforementioned oil dipping platform 3, there is a waste oil tank 11. The waste oil tank 11 is connected to the oil dipping platform 3 through a support column 12. The upper and lower ends of the support column 12 are respectively fastened to the oil dipping platform 3 and the waste oil tank 11 through fasteners. By setting up the waste oil tank 11, overflowing waste oil can be collected.

[0027] The oil dipping heads 9 on the upper and lower sides of the oil outlet 10 are equipped with sealing rings. When dipping in oil, the sealing rings are sealed to the inner wall of the oil dipping head, and the sealing of the sealing rings can prevent the lubricating oil from leaking.

[0028] In this embodiment, preferably, three oil outlets 10 are provided, and the included angle between adjacent oil outlets 10 is 120°.

[0029] The oil drum 1 is provided with an oil filling port 13 on one side. Lubricating oil can be added to the oil drum 1 through the oil filling port 13 to replenish the lubricating oil. A valve is provided at the oil filling port 13. When oil needs to be added, the valve is opened and closed after the oil is added. The other side of the oil drum 1 is connected to the first one-way valve 4 through the first oil supply pipe 14. The second one-way valve 5 is connected to the oil dipping platform 3 through the second oil supply pipe 15.

[0030] The aforementioned oil pressure cylinder 6 is located at the top of the oil tank 1 and drives the oil pressure piston inside the oil tank 1. The oil supply cylinder 7 is located at the bottom of the oil supply valve 2 and drives the oil supply piston 16 inside the oil supply valve 2. The first one-way valve 4 is located on one side of the oil supply valve 2, and the second one-way valve 5 is located at the top of the oil supply valve 2.

[0031] The oil dipping platform 3 is provided with a radial oil delivery channel 17 with one end open and a connector installed. The oil dipping head 9 is provided with an axial oil delivery channel 18 that connects the radial oil delivery channel 17 and the oil outlet 10. The lubricating oil in the oil tank 1 is delivered sequentially through the first oil delivery pipe 14, the first one-way valve 4, the oil supply valve 2, the second one-way valve 5, the second oil delivery pipe 15, the radial oil delivery channel 17, the axial oil delivery channel 18 and the oil outlet 10.

[0032] 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.
