Description

Technical Field

[0001] The present invention relates to a sealing ring assembly production line for crimp-type pipe fittings, belonging to the technical field of sealing ring assembly.

Background Art

[0002] Among sealing rings, O-ring seals are the most commonly used. O-ring seals are the most widely used sealing components on various mechanical equipment. Their cross-sectional structure is extremely simple, and they have a self-sealing effect. The sealing performance is reliable, and they are mainly used for static seals and reciprocating motion seals.

[0003] Pipe fittings are a general term for components in a pipeline system that play roles such as connection, control, direction change, flow diversion, sealing, and support. They are an important part of connecting pipes to pipelines. Pipe fittings are mostly made of the same material as the pipes, and include elbows, straight pipes, tees, and reducers, etc. Pipe fittings are generally used to transport fluids. To prevent fluid leakage, it is generally necessary to seal the connection between the pipe fittings and the pipeline, usually by installing an O-ring seal inside the pipe fittings.

[0004] The assembly of the O-ring seals of existing pipe fittings generally relies on manual assembly. Since a pipe fitting has multiple ports, workers need to install O-ring seals on each port, which is extremely time-consuming and laborious for workers, and the assembly efficiency is limited. At the same time, there may be a problem that some ports are missed, resulting in a relatively high unqualified rate of products, and later inspections and tests are required, which also greatly increases the production cost. At the same time, due to the low assembly speed of manual operation, it is difficult to meet the needs of automated assembly and the fierce market competition. Secondly, at present, the inspection of pipe fittings only judges whether the pipe fittings are qualified by observing whether there is a sealing ring inside the pipe fittings. This will result in a large quality difference in pipe fittings. Even if there is a sealing ring inside some pipe fittings, when the pressure of the sealing ring on the pipe is small, its sealing performance will be low. Therefore, even if there is a sealing ring inside the pipe fitting, its quality may still be unqualified.

Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a sealing ring assembly production line for crimp-type pipe fittings, which can automatically assemble, detect, label, and sort pipe fittings, and can improve the production efficiency of pipe fittings.

[0006] To solve the above technical problem, the present invention adopts the following technical solutions:

The assembly station, inspection station, material taking station, and labeling and sorting station are arranged along the circumference of the turntable, where:

[0008] The turntable is provided with a first driver and at least five pipe fitting workstations for placing pipe fittings to be processed. The first driver is used to control the rotation of the turntable so that the pipe fitting workstations sequentially pass through the assembly station, the inspection station, and the material taking station.

[0009] The assembly station includes a feeding device and a loading device. The feeding device is used to convey the sealing ring to the loading device, and the loading device installs the sealing ring into the pipe fitting.

[0010] The inspection station includes an inspection device. The inspection device detects the pressure value generated by the sealing ring in the pipe fitting on the inspection device. The controller records the inspection result and judges whether the quality of the inspected pipe fitting is qualified.

The assembly station, inspection station, material taking station, and marking and sorting station are arranged circumferentially along the turntable 2. This embodiment is installed on a support table 1. The turntable 2 is provided with a first driver and 6 pipe fitting stations 3 for placing pipe fittings 33 to be processed. The first driver is used to control the rotation of the turntable 2 so that the pipe fitting stations 3 pass through the assembly station, inspection station, and material taking station in sequence. The assembly station includes a feeding device 5 and a loading device 4. The feeding device 5 is used to convey the sealing ring 54 to the loading device 4, and the loading device 4 installs the sealing ring 54 into the pipe fitting 33. The inspection station includes an inspection device 6. The inspection device 6 detects the pressure value generated by the sealing ring 54 in the pipe fitting 33 on the inspection device 6.

The feeding device 5 provides the sealing ring 54 to the loading device 4, and the loading device 4 installs the sealing ring 54 into the interior of the pipe fitting 33, realizing the automatic assembly of the sealing ring 54. A large amount of manual labor can be saved, and the labor cost can be reduced. In addition, automatic assembly can avoid mistakes caused by manual operation, improving the assembly accuracy and the qualified rate of products.

[0052] Secondly, in this embodiment, the pressure value generated by the sealing ring 54 on the detection device 6 is detected to determine whether the assembly of the sealing ring 54 in the pipe fitting 33 is qualified, improving the detection standard and making the detection result more accurate. It can further eliminate inferior products and improve the qualified rate of products. In addition, the detection device 6 can detect all assembled pipe fittings 33, which can avoid mistakes such as omission caused by workers' long-term repetitive operations.

[0053] In addition, the controller 12 in this embodiment records the results detected by the detection device 6, determines whether the detected pipe fitting 33 is qualified based on the detection results and records it. When the pipe fitting 33 enters the marking and sorting station, the sorting device 8 differentiates the pipe fitting 33 according to the detection results recorded by the controller 12. The sorting result is highly accurate and the sorting speed is fast, which can greatly improve the sorting efficiency.

[0054] Furthermore, in this embodiment, a plurality of pipe fitting stations 3 are provided on the turntable 2. The turntable 2 enables the pipe fitting stations 3 to pass through the assembly station, the detection station and the material taking station in sequence, enabling each station to operate simultaneously, which can greatly improve the production efficiency of this embodiment. The devices at each station replace manual operations, which can save a large amount of labor costs and also reduce errors in production, further improving the qualified rate of products.

[0055] Regarding the turntable 2, 6 pipe fitting stations 3 fixed on the surface of the turntable 2 are provided on the turntable 2. The first driver controls the rotation of the turntable 2, enabling the pipe fitting stations 3 to pass through the assembly station, the detection station and the material taking station in sequence. When the assembly station assembles the pipe fitting 33, the pipe fitting station 3 is in the assembly area. When the detection station detects the pipe fitting 33, the pipe fitting station 3 is in the detection area. When the material taking station extracts the pipe fitting 33, the pipe fitting station 3 is in the material taking area.

[0056] Regarding the assembly station, in this embodiment, the assembly station includes a feeding device 5 and a loading device 4. The feeding device 5 is provided with a vertically distributed slide rail 53. The slide rail 53 includes an upper port 530 and a lower port 531. The upper port 530 is connected to the vibrating bowl 50. The sealing ring 54 enters the slide rail 53 from the vibrating bowl 50. At the lower port 531, there is a feeding plate 52. The sealing ring 54 enters the U-shaped groove 521 of the feeding plate 52 from the lower port 531 of the slide rail 53. The feeding device 5 is also provided with a feeding cylinder 51. The feeding cylinder 51 controls the feeding plate 52 to send the sealing ring 54 to the loading device 4. The loading device 4 includes a first loading cylinder 41, a loading rod 42, and a second loading cylinder 43. The second loading cylinder 43 controls the first loading cylinder 41 and the loading rod 42 to move up and down, so that the loading rod 42 obtains the sealing ring 54 from the feeding plate 52. The first loading cylinder 41 controls the loading rod 42 to make a reciprocating motion towards the pipe fitting station 3. The loading rod 42 installs the sealing ring 54 into the pipe fitting 33.

[0057] Regarding the inspection station, the inspection device 6 includes an inspection driver 62 and an inspection rod 61. The inspection driver 62 controls the inspection rod 61 to extend into the interior of the pipe fitting 33. After the sealing ring 54 is installed into the pipe fitting 33, the sealing ring 54 protrudes from the inner wall of the pipe fitting. Therefore, when the inspection rod 61 extends into the pipe fitting 33, the sealing ring 54 will exert a pressure on the inspection rod 61. A pressure sensor is provided on the inspection rod 61. The pressure sensor is connected to the controller 12. The pressure sensor is used to detect the pressure exerted by the sealing ring 54 on the inspection rod 61 and transmit the detection result to the controller 12. This pressure value is N. A standard pressure range M is provided in the controller 12. The controller 12 compares the pressure value N with M. When N is within the range of M, the inspected pipe fitting 33 is qualified. When N is not within the range of M, the inspected pipe fitting 33 is unqualified. The controller 12 records the information of the inspected pipe fitting.

The first sorting cylinder moves the workbench 86 according to the information of the pipe fitting 33 recorded in the controller 12. When the pipe fitting 33 is qualified, the workbench 86 moves to the qualified product station. When the pipe fitting 33 is unqualified, the workbench 86 moves to the defective product station. The qualified product station includes a first sorting driver 81 and a first pushing block 82. The defective product station includes a second sorting driver 83 and a second pushing block 84. After the workbench 86 moves to the qualified product station, the first sorting driver 81 controls the first pushing block 82 to push the pipe fitting 33 into the qualified product channel 91. After the workbench 86 moves to the defective product station, the second sorting driver 83 controls the second pushing block 84 to push it to the defective product station. The qualified product channel 91 is installed obliquely on the support table 1, and the defective product channel 92 is embedded in the support table 1, and one of its ports is provided on the surface of the support table 1.

[0060] In addition, a second sorting cylinder 85 and a limit post 87 are provided under the workbench 86. The second sorting cylinder 85 controls the limit post 87 to reciprocate in the vertical direction. The limit post 87 is used to prevent the pipe fitting 33 on the workbench 86 from detaching from the workbench 86.

[0061] In addition, a first limiter 20 and a first steering device 21 are provided in this embodiment. The first limiter 20 is provided on the fixed disk.

In this embodiment, the workbench disk 32 is generally circular. A second groove 320 is provided on the upper surface of the workbench disk 32. The second groove 320 is in a cross shape, and a rotation stopping block 321 is installed in the middle of the second groove 320. When the workbench disk 32 is in the first groove 310, the rotation stopping block 321 and the first groove 310 cooperate to limit the rotation of the workbench disk 32. The workbench disk 32 is also provided with a third groove corresponding to the convex post 215.

[0063] When the pipe 33 enters the assembly area, the limit driver 201 in the first limiter 20 controls the limit rod 202 to contact the upper surface of the pipe, so that the pipe is confined in the second groove 320, and the steering cylinder 211 in the first diverter 21 below the loading area controls the steering assembly to rise, so that the convex column 215 on the surface of the steering head enters the third groove of the work station 32, and lifts the work station 32 upward, at this time, the limit rod 202 above the pipe retracts, and the limit rod 202 is always in contact with the pipe under the action of the spring 202;

[0064] In this embodiment, the detection area is further provided with a second limiter and a second diverter. The structure and function of the second limiter and the second diverter are exactly the same as those of the first limiter and the first diverter, so they are not described here one by one.
