Description

Technical Field

[0001] This utility model belongs to the technical field of valve assembly equipment, specifically a flexible ring feeding device. Background Technology

[0002] In existing technologies, flexible rings such as sealing rings and color rings are typically fed using a single rotary vibratory feeder during valve body assembly. The rotary vibratory feeder arranges the flexible rings in an orderly manner and transports them to the end guide rail through vibration. However, because the guide rail is designed with an open structure at the top, and the flexible rings such as sealing rings and color rings are usually made of silicone, rubber, or other elastic materials, which are not only soft and highly elastic but also lightweight, they are easily affected by the vibration of the rotary vibratory feeder during transport on the guide rail. This can easily lead to the flexible rings detaching from the guide rail at the end of the rotary vibratory feeder due to excessive vibration amplitude, seriously affecting the feeding efficiency of the flexible ring assembly. Utility Model Content

[0003] Purpose of the utility model: To provide a flexible ring feeding device, which reduces the probability of the flexible ring falling off the discharge guide rail and improves the feeding efficiency of the flexible ring by cooperating with a rotating vibrating plate, a linear vibrating feeder for discharge, and the suction hole of the discharge guide rail, thus solving the problem of high rate of flexible ring falling off the guide rail in the prior art.

[0004] The technical solution of this utility model is as follows: A flexible ring feeding device includes: a rotary vibratory plate, a discharge guide rail and a discharge linear vibratory feeder.

[0005] The discharge guide rail is located at the discharge end of the rotary vibratory feeder, and the discharge linear vibratory feeder is installed on the discharge guide rail.

[0006] The discharge guide rail is provided with multiple suction holes, which are used to connect to a vacuum device.

[0007] The discharge guide rail applies an adsorption force to the flexible ring through suction holes.

[0008] The discharge linear vibrating feeder causes the flexible ring on the discharge guide rail to move away from the rotating vibrating disc.

[0009] In a further embodiment, the suction hole distribution area is located at the end of the discharge guide rail away from the rotating vibratory disk.

[0010] The length of the suction hole distribution area is less than one-third of the total length of the discharge guide rail, which allows the accumulated flexible rings to fall onto the return guide rail and be quickly returned at the end of the discharge guide rail near the rotating vibrating plate, thus avoiding the accumulation of flexible rings at the discharge end of the discharge guide rail and interference with the outer O-ring assembly gripper picking up the material.

[0011] In a further embodiment, the diameter of the suction hole is less than or equal to the cross-sectional diameter of the flexible ring.

[0012] In a further embodiment, the flexible ring feeding device also includes: a return guide rail and a return linear vibrating feeder.

[0013] The return guide rail is located at the feed end of the rotary vibratory feeder, the return guide rail is located below the discharge guide rail, and the return linear vibratory feeder is installed on the return guide rail.

[0014] The linear vibrating feeder for returning material moves the flexible ring on the return guide rail toward the rotating vibrating plate. When the flexible ring on the discharge guide rail occasionally slips off, the return guide rail can catch the slipped flexible ring. The linear vibrating feeder for returning material allows the flexible ring on the return guide rail to quickly return to the rotating vibrating plate, further improving the conveying rhythm of the flexible ring.

[0015] In a further embodiment, the feeding surface of the discharge guide rail is a sloping structure.

[0016] The feeding surface of the return guide rail is located below the feeding surface. The inclined structure allows the flexible ring to unload to one side of the discharge guide rail, which can reduce the number and area of ​​the return guide rails.

[0017] In a further embodiment, the diameter of the suction hole is less than or equal to the cross-sectional diameter of the flexible ring.

[0018] In a further embodiment, the rotating vibratory feeder is a CNC vibratory feeder, and the probability of scratches on the surface of the flexible ring can be reduced by the integrally molded top plate.

[0019] In a further embodiment, the flexible O-ring feeding device further includes a moving mechanism and an outer O-ring assembly gripper.

[0020] The moving mechanism is located on one side of the discharge guide rail, and the outer O-ring assembly gripper is installed on the moving mechanism. The moving mechanism and the outer O-ring assembly gripper are used to transport the flexible ring on the discharge guide rail.

[0021] In a further embodiment, the moving mechanism is a two-axis moving mechanism or a three-axis moving mechanism.

[0022] The beneficial effects of this utility model are: This application uses the suction holes of the discharge guide rail to adsorb the flexible ring, which reduces the probability of the flexible ring falling off the discharge guide rail. Combined with the discharge linear vibrating feeder, it applies vibration to the flexible ring on the discharge guide rail, moving it away from the rotating vibrating plate, thereby improving the feeding efficiency of the flexible ring and solving the problem of low feeding efficiency of the flexible ring in the prior art.

[0031] The discharge guide rail 2 is provided with multiple suction holes 21, which are used to connect to the vacuum device.

[0032] The discharge guide rail 2 applies an adsorption force to the flexible ring through the suction hole 21. The flexible ring can be a sealing ring or a color ring used for valve body assembly.

[0033] The discharge linear vibrating feeder causes the flexible ring on the discharge guide rail 2 to move away from the rotating vibrating plate 1.

[0035] The linear vibrating feeder for returning material causes the flexible ring on the return guide rail 4 to move closer to the rotating vibrating plate 1.

[0036] like Figure 3 The moving mechanism 6 shown is located on one side of the discharge guide rail 2. The outer O-ring assembly gripper 7 is installed on the moving mechanism 6. The moving mechanism 6 and the outer O-ring assembly gripper 7 are used to transport the flexible ring on the discharge guide rail 2.

[0037] The moving mechanism 6 can be a two-axis moving mechanism 6 or a three-axis moving mechanism 6, such as Figure 3 The moving mechanism 6 shown is a two-axis moving mechanism 6.

[0038] like Figure 2 The area where the suction holes 21 are distributed is located at the end of the discharge guide rail 2 away from the rotating vibrating plate 1.

[0039] The length of the area where the suction holes 21 are distributed is less than or equal to one-third of the total length of the discharge guide rail 2, such as Figure 2 The length of the area where the suction holes 21 are distributed is one-fifth of the total length of the discharge guide rail 2.
