Description

Technical Field

[0001] This utility model belongs to the technical field of intelligent toilet assembly equipment, and relates to an O-ring feeding and assembly device for 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] The aforementioned toilet inlet valve assembly equipment only provides an O-ring assembly station, which cannot accurately position or automatically assemble the O-rings. Therefore, it is necessary to develop an intelligent toilet pressure regulating valve O-ring feeding and assembly device that enables accurate positioning, rapid feeding and assembly, and thus completes the automatic assembly of the O-rings.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figures 1-4 :

[0022] An O-ring feeding and assembly device for an intelligent toilet pressure regulator includes an O-ring positioning fixture 1 connected to an O-ring conveying device. The O-ring positioning fixture 1 is provided with an O-ring positioning groove 2 adapted to the O-ring. An O-ring inner support gripper 3 is provided above the O-ring positioning fixture 1. The O-ring inner support gripper 3 includes several circumferentially spaced fan-shaped grippers. An O-ring assembly push plate 6 driven by an O-ring assembly cylinder 5 is provided on one side of the O-ring inner support gripper 3. After the fan-shaped grippers 4 are connected to the back cover insertion post, the O-ring assembly push plate 6 drives the O-ring to move downward and fit into the back cover insertion post.

[0023] Furthermore, the O-ring assembly push plate 6 is provided with a through hole 7 that is fitted onto the fan-shaped claw 4. The through hole 7 and the fan-shaped claw 4 are coaxially arranged and clearance-fitted.

[0024] Furthermore, the O-ring inner support gripper 3 is driven to slide up and down by the O-ring lifting cylinder 8, and the O-ring lifting cylinder 8 is driven to slide horizontally by the O-ring translation cylinder 9. Specifically, the O-ring lifting cylinder 8 is fixed on the lifting cylinder mounting plate, and the lifting cylinder mounting plate is provided with a vertical guide rail for the O-ring inner support gripper 3 to slide; the O-ring translation cylinder 9 is fixed on the translation cylinder mounting plate, and the translation cylinder mounting plate is provided with a horizontal guide rail for the O-ring lifting cylinder 8 to slide; the O-ring inner support gripper 3 and the O-ring assembly push plate 6 are fixed on the same mounting plate.

[0025] The specific structure of the O-ring conveying device in this embodiment is as follows: the O-ring positioning groove 2 includes a first positioning groove 10 and a second positioning groove 11 in a T-shape; the O-ring conveying device includes an O-ring conveying vibratory plate 12; the feeding track 13 of the O-ring conveying vibratory plate 12 is connected to the inlet of the first positioning groove 10; the outlet of the first positioning groove 10 is connected to the middle of the second positioning groove 11; and a pusher plate 15 driven by a pusher cylinder 14 is slidably arranged in the second positioning groove 11.

[0026] Furthermore, the end of the second positioning groove 11 forms an O-ring feeding end 14, and an avoidance hole 17 is provided below the O-ring feeding end 16, which provides downward space for the fan-shaped claw 4.

[0027] The O-ring feeding and assembly process in this embodiment is as follows: The O-ring to be assembled is placed into the O-ring conveying vibratory feeder 12. The O-ring conveying vibratory feeder 12 is started, and the O-ring enters the first positioning groove 10 along the feeding track 13, and then enters the second positioning groove 11 from the first positioning groove 10 (the O-ring can enter the second positioning groove 11 using conveying inertia, or an air blowing device or pushing device can be added to make it enter the second positioning groove 11). The pushing cylinder 14 is started, and the pushing plate 15 pushes the O-ring in the second positioning groove 11 into the O-ring feeding end 16. The O-ring lifting cylinder 8 drives the O-ring inner support gripper 3 to move downwards and insert into the O-ring. The O-ring inner support gripper 3 is slightly... The slight opening causes the O-ring to deform and fit onto the inner support gripper 3. Then, the inner support gripper 3 moves the O-ring upward. The inner support gripper 3 fully opens to support the O-ring. The O-ring translation cylinder 9 drives the O-ring lifting cylinder 8 to move above the assembly positioning fixture (the assembly positioning fixture carries the rear cover and is set on the turntable driven by the divider). The O-ring lifting cylinder 8 drives the inner support gripper 3 downward to mate with the rear cover insertion post. After the fan-shaped claw 4 mates with the rear cover insertion post, the O-ring assembly push plate 6 drives the O-ring downward to fit onto the rear cover insertion post, completing the O-ring assembly. Afterward, the O-ring feeding mechanism resets.

[0028] To ensure stable delivery of the O-ring in the O-ring positioning groove 2, a pressure plate 18 is provided on the upper cover of the O-ring positioning groove 2; preferably, the pressure plate 18 is located above the first positioning groove 10.

[0029] Furthermore, a first sensor 19 for detecting the positioning status of the O-ring is provided above the junction of the first positioning groove 10 and the second positioning groove 11, and a second sensor 20 for detecting the positioning status of the O-ring is provided on one side of the O-ring feeding end 16. By setting the first sensor 19 and the second sensor 20, it is possible to detect whether the O-ring has moved to the predetermined position.

[0030] 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.
