[0002] One-way valve, also known as check valve or non-return valve, is an automatic valve that allows fluid (liquid or gas) to flow in only one direction and automatically closes under reverse pressure to prevent backflow. It is widely used in hydraulic systems, pneumatic systems, automobile engines, medical devices, household appliances and industrial pipeline systems due to its simple structure and high reliability. With the increasing demand for automation, high efficiency and high reliability in modern industry, there is an urgent need for the development of one-way valve automatic assembly equipment.

[0003] The common one-way valve structure in the prior art usually includes valve seat, valve core, valve cover and sealing element and other components.

[0021] like Figures 1 to 14 As shown, an automated assembly system for a one-way valve includes a frame 1, a workbench 2, and a valve seat feeding device 3, a valve disc feeding device 4, a valve cover assembly device 5, and a sealing component feeding device arranged sequentially along the working circumference. The workbench 2 is mounted on the frame 1 and rotatably connected to the frame 1. The workbench 2 is provided with an assembly seat 21, and multiple assembly seats are evenly arranged along the circumference. The valve seat feeding device 3 is used to feed the valve seat 101 onto the assembly seat. The valve disc feeding device is used to feed the valve disc 102 into the valve seat. The valve cover assembly device is used to feed the valve cover 103 into the valve seat 101 and press the valve disc 102 inside. The sealing component feeding device is used to feed the sealing component onto the outer wall of the valve seat 101.

[0022] This invention provides an automated assembly system for one-way valves, which can automatically feed and assemble the various components of the one-way valve. It boasts a high degree of automation, reduces manual assembly workload, increases work efficiency, and ensures consistent quality after assembly, better meeting the assembly needs of modern industry. Specifically, the workbench 2 is equipped with multiple assembly seats 21. Rotation of the workbench 2 allows for simultaneous automatic assembly of multiple one-way valves, resulting in higher assembly efficiency. The valve seat feeding device 3 feeds the valve seat onto the assembly seats, and the valve disc feeding device 4 feeds the valve disc and assembles it into the valve seat. In this application, the valve disc is a steel ball. The valve cover assembly device 5 feeds the valve cover into the valve seat and presses it into place. The sealing component feeding device feeds the sealing component onto the outer wall of the valve seat and presses it into place. In this application, the sealing component consists of a gasket and a sealing ring, which are sequentially pressed onto the outer wall of the valve seat.

[0023] Based on the above technical solution, a snap ring assembly device 9 is also included at the end of the sealing component feeding device. The snap ring assembly device 9 includes a snap ring feeding vibratory plate 91, a snap ring feeding column 92, a push plate 93, a push drive mechanism 94, a snap ring clamping mechanism 95, and a snap ring drive mechanism 96. The snap ring feeding column 92 is located at the end of the feeding vibratory plate 91, and the snap ring 106 slides along the snap ring feeding column 92. The push plate 93 is provided with a snap ring receiving groove 931. The push drive mechanism 94 drives the push plate 93 to reciprocate. The snap ring clamping mechanism 95 is used to clamp and press the snap ring 106 into the valve seat 101. The snap ring drive mechanism 96 drives the snap ring clamping mechanism 95 to move in the vertical direction.

[0024] Based on the above technical solution, the snap ring clamping mechanism 95 includes an outer sliding sleeve 951, an inner clamping sleeve 952, and a clamping drive mechanism 953. The outer sliding sleeve 951 is sleeved on the outside of the inner clamping sleeve 952. The inner clamping sleeve 952 is driven by the clamping drive mechanism 953 to slide and connect with the outer sliding sleeve. The bottom end of the inner clamping sleeve 952 is provided with elastic clips 955 spaced apart along the circumferential direction. The bottom end of the outer sliding sleeve 951 is provided with pressure plates 954 spaced apart. The pressure plates 954 and elastic clips 955 are alternately arranged.

[0025] Based on the above technical solution, the outer wall of the elastic clip 955 is provided with a clamping groove 956. By providing the clamping groove 956, and in conjunction with the elastic properties of the elastic clip, as the inner clamping sleeve 952 moves downwards towards the retaining spring 106, the retaining spring 106 is clamped within the clamping groove 956, resulting in a more stable clamping. Preferably, the bottom surfaces of the multiple pressure plates are arranged in a spiral shape. By setting the bottom surfaces of the multiple pressure plates in a spiral shape—that is, the bottom surfaces of the multiple pressure plates are not on the same horizontal plane, but spiral from high to low in the circumferential direction—the edges of the retaining spring are pressed down sequentially during the downward pressing of the retaining spring, resulting in a better pressing and closing effect on the retaining spring opening.

[0026] Preferably, the push drive mechanism 94 and the snap ring drive mechanism 96 are configured as cylinders or electric push rods; or they can adopt linear modules, ball screw pairs, or other structures, as long as they can drive the linear movement of the push plate and the snap ring clamping mechanism.

[0027] Based on the above technical solution, the snap ring assembly device 9 further includes an auxiliary assembly mechanism correspondingly disposed below the snap ring clamping mechanism 95. The auxiliary assembly mechanism includes a support plate 971, an auxiliary mounting base 972, and an auxiliary drive assembly 973. The support plate 971 is driven by the auxiliary drive assembly 973 to move in the vertical direction. The auxiliary mounting base 972 is disposed in a receiving hole on the support plate 971. The auxiliary mounting base 972 has a hollow structure inside and an inverted trapezoidal longitudinal section. The bottom opening of the auxiliary mounting base 972 is adapted to the top opening of the valve seat 101.

[0028] This embodiment also includes a snap ring assembly device 9 for feeding the snap ring, and for assembling the snap ring to the top position of the valve cover inside the valve seat and pressing it tight. Before assembly, the snap ring is a ring with an opening, and in the initial feeding state, it is located inside the snap ring feeding vibratory plate 91.

[0029] During feeding: the snap ring is conveyed to the snap ring feeding column 92 by the snap ring feeding vibratory plate 91. The snap ring slides down along the snap ring feeding column 92 into the snap ring receiving groove 931 of the push plate 93. Under the action of the push drive mechanism 94, the snap ring on the push plate 93 is conveyed to the snap ring clamping mechanism 95. Preferably, a position detection switch is provided at this position to detect the snap ring that has been conveyed to the position in time and to clamp and feed it in time.

[0030] During clamping: the snap ring drive mechanism 96 drives the snap ring clamping mechanism 95 to move downward to the snap ring position, the clamping drive mechanism 953 drives the inner clamping sleeve 952 to move downward, and the elastic clamping piece 955 passes through the inner diameter of the snap ring and fixes it under the action of elastic force; under the action of the snap ring drive mechanism 96, it is further conveyed downward to the valve seat on the mounting base 21, at which time the bottom end of the auxiliary mounting base 972 abuts against the top end of the valve seat.

[0031] During assembly, the inner clamping sleeve 952 and its elastic clamping piece 955 move upward under the drive of the clamping drive mechanism 953, while the outer sliding sleeve 951 remains stationary. This pushes the snap ring clamped on the elastic clamping piece 955 into the conical sleeve with an inverted trapezoidal longitudinal section inside the auxiliary mounting base 972. Then, the inner clamping sleeve 952 moves downward. Under the action of the conical sleeve and the pressure plate with a spiral arrangement on the bottom end face, the opening of the snap ring gradually narrows and moves downward inside the conical sleeve, pressing it into the valve seat and onto the top of the valve cover. Then, the inner clamping sleeve moves downward again, further pressing the snap ring to the specified position, thus completing the snap ring loading and assembly process.

[0032] More preferably, the installation status of the retaining ring can be detected by the positioning information of the drive cylinder of the inner clamping sleeve and the subsequent visual inspection camera.

[0033] Based on the above technical solution, the valve seat feeding device 3 includes a valve seat material tray 31, a first valve seat support plate 32, a second valve seat support plate 33, a support plate driving mechanism 34, and a valve seat driving mechanism 35. The valve seat material tray 31 is mounted on the frame 1 and has multiple valve seat placement holes 311 at its top. The first valve seat support plate 32 and the second valve seat support plate 33 are symmetrically arranged and driven to move in opposite directions by the support plate driving mechanism 34. The valve seat driving mechanism 35 drives the support plate driving mechanism 34 to slide along different directions of the frame.

[0034] In this embodiment, an internal support gripper is used, namely, a first valve seat support plate 32 and a second valve seat support plate 33 arranged opposite each other. Driven by the support plate driving mechanism 34, the first valve seat support plate 32 and the second valve seat support plate 33 move away from each other to clamp and fix the inner diameter of the valve seat to be loaded. Then, the valve seat driving mechanism 35 moves the clamped and fixed valve seat on the x-axis and y-axis to the corresponding position on the assembly seat on the worktable 2. Then, it is driven to move on the z-axis until the valve seat is placed in the assembly seat. Then, the support plate driving mechanism 34 drives the first valve seat support plate 32 and the second valve seat support plate 33 to move closer to each other, releasing the clamp on the valve seat. Returning to the initial position, the loading and assembly of the next valve seat is then performed.

[0035] In one preferred embodiment, the support plate driving mechanism 34 is configured as two cylinders or electric push rods, which drive the first valve seat support plate 32 and the second valve seat support plate 33 to move in opposite directions respectively; in another preferred embodiment, the support plate driving mechanism 34 is configured as a two-way screw mechanism, a double-acting hydraulic cylinder or a double-acting air cylinder, that is, the same driver can simultaneously drive the first valve seat support plate and the second valve seat support plate to move in opposite directions.

[0036] In a preferred embodiment, the valve seat drive mechanism 35 is configured as a Cartesian coordinate robot; in other preferred embodiments, the valve seat drive mechanism may also be a mechanical drive mechanism that can move in three dimensions, such as linear modules set in different three-dimensional directions of x-axis, y-axis and z-axis, to realize linear conveying of the valve seat in different directions.

[0037] Preferably, the output free end of the valve seat drive mechanism 35 is provided with a rotating mechanism 38. Two sets of support plate drive mechanisms are symmetrically arranged on the rotating mechanism 38, i.e., two support plate drive mechanisms set at 90 degrees are arranged on the same rotating mechanism. Rotation of 180° allows for switching of the grippers, improving work efficiency. Preferably, one support plate drive mechanism is provided on the rotating mechanism 38 for loading the valve seat onto the assembly base, and a clamping mechanism is provided on the other side to clamp the assembled product out of the assembly base. More preferably, the rotating mechanism 38 is a rotary cylinder.

[0038] Preferably, the valve seat drive mechanism 35 is also equipped with a vision camera 39. After the one-way valve is assembled, the vision camera first checks whether any parts are missing, and then places them into different trays according to whether they are qualified, so as to facilitate subsequent operations.

[0039] Preferably, the bottom end of the valve seat material tray 31 is provided with a material support plate 36, the material support plate 36 is slidably connected to the frame 1 through the material tray drive mechanism 37, and the valve seat material tray 31 and the material support plate 36 are fixed together by a snap fastener.

[0040] More preferably, the tray drive mechanism 37 is configured as a linear module, a ball screw pair, or other common mechanical drive structure capable of driving linear motion; it is understood that the linear module, ball screw pair, and other common mechanical structures can be obtained from the prior art, and this application does not involve any improvement to the specific structure of the corresponding drive mechanism.

[0041] Based on the above technical solution, the valve disc feeding device 4 includes a hopper 41, a dropping plate 42, a support platform 43, a conveying trough 44, a dropping drive mechanism 45, and a feeding pipe 46. The hopper 41 is mounted on the frame 1 and filled with steel balls. The dropping plate 42 is mounted inside the hopper 41 and is inclined. The support platform 43 is mounted on the side of the dropping plate 42 located inside the hopper 41 and is slidably connected to the inner side wall of the hopper 41. The top of the support platform 43 is provided with a carrying trough 431 for accommodating steel balls. The conveying trough 44 is fixedly mounted on the outer side wall of the hopper 41. The dropping drive mechanism 45 is located at the end of the conveying trough 44 and is used to convey steel balls into the feeding pipe 46. The end of the feeding pipe 46 is correspondingly located above the workbench 2.

[0042] Based on the above technical solution, the material discharge driving mechanism 45 includes a material discharge cylinder 451, a material blocking plate 452, and a limiting frame 453. The material blocking plate 452 abuts against the end of the material conveying trough 44 and is driven to slide by the material discharge cylinder 451. The limiting frame 453 is fastened to the top of the material blocking plate 452 and forms a channel between them that allows the steel ball to slide. The first end of the feeding pipe 46 is located at the bottom end of the material blocking plate 452.

[0043] More preferably, the feeding pipe 46 is provided with an air blowing port 461, which is located near the beginning of the feeding pipe 46. By providing an air blowing port 461 on the feeding pipe 46, the conveying of steel balls within the feeding pipe 46 can be assisted.

[0044] More preferably, a vision inspection component is also provided above the material conveying trough 44.

[0045] More preferably, a cover is provided on one side of the top of the hopper 41, and the cover is hinged to the hopper.

[0046] The bottom surfaces of the supporting trough 431 and the conveying trough 44 are both inclined. Through the inclined top of the supporting platform 43 and the conveying trough 44, steel balls can be automatically conveyed under the action of gravity.

[0047] Preferably, the support platform 43 is driven by the support drive mechanism 47 to reciprocate vertically along the inner sidewall of the hopper 41. More preferably, the support drive mechanism 47 includes an electric push rod 471 and a connecting plate 472, one end of the connecting plate 472 being disposed at the output end of the electric push rod 471, and the other end being fixedly connected to the bottom end of the support platform 43. More preferably, guide grooves are provided on both sides of the support platform 43, and guide blocks adapted to the guide grooves are provided on the sidewall of the hopper.

[0048] Preferably, the support platform 43 is provided with a plurality of elongated through holes 432 along its length, the width of which is smaller than the diameter of the steel ball. By providing a plurality of elongated through holes 432 on the main structure of the support platform 43, which cooperate with the inclined dropping plate 42, the position of the steel ball can be limited, thereby facilitating feeding into the support trough 431 at the top of the support platform 43.

[0049] When the valve disc feeding device 4 is working, the hopper 41 is filled with steel balls. Under the action of the inclined dropping plate 42, the steel balls slide in the inclined direction to one side of the support platform 43. Preferably, since the support platform 43 has multiple elongated through holes 432, the steel balls can be limited by the elongated through holes 432. The support platform 43 slides downward under the drive of the support driving mechanism 47, and the steel balls roll into the support material trough 431 at the top of the support platform. They are then conveyed in the inclined support material trough 431 towards the conveying trough 44, and conveyed through the conveying trough 44 until they reach the position of the dropping driving mechanism 45. At this time, the blocking plate 452 is located at the end of the conveying trough 44, which blocks the inlet of the feeding pipe 46. When feeding, the dropping cylinder 451 is activated, which drives the blocking plate 452 to slide and open the inlet of the dropping pipe 46. The steel balls fall into the feeding pipe 46 and are conveyed to the assembly seat 21 on the workbench 2, completing the process of feeding the steel balls and assembling them into the valve seat.

[0050] Based on the above technical solution, the valve cover assembly device 5 includes a valve cover feeding vibratory plate 51, a feeding seat 52, a distributing plate 53, a distributing drive mechanism 54, a valve cover clamping mechanism 55, and a valve cover drive mechanism 56. The feeding vibratory plate 51 is fixedly mounted on the frame 1 and is filled with valve covers. The feeding seat 52 abuts against the end of the feeding vibratory plate 51 and is provided with a valve cover conveying channel that allows the valve covers to pass through. The distributing plate 53 is mounted on the feeding seat 52 and is driven to move by the distributing drive mechanism 54. The distributing plate 53 is provided with a valve cover receiving groove. The valve cover clamping mechanism 55 is used to clamp the valve covers. The valve cover drive mechanism 56 drives the valve cover clamping mechanism 55 to move in different directions along the frame.

[0051] Preferably, the material distribution drive mechanism is configured as a cylinder or an electric push rod; or a linear module, ball screw pair or other structure can be used, as long as it can drive the linear movement of the material distribution plate.

[0052] Based on the above technical solution, the valve cover clamping mechanism 55 includes a first valve cover clamping plate 551, a second valve cover clamping plate 552, and a clamping plate driving assembly 553. The first valve cover clamping plate 551 and the second valve cover clamping plate 552 are symmetrically arranged and driven by the clamping plate driving assembly 553 to move in opposite directions.

[0053] In a preferred embodiment, the clamping plate driving assembly 553 and the support plate driving mechanism 34 use the same driving mechanism. The valve cover driving mechanism 56 uses the same driving mechanism as the valve seat driving mechanism 35, as long as it can drive the first valve cover clamping plate and the second valve cover clamping plate to move in different directions to realize the loading of the valve cover.

[0054] The valve cover driving mechanism 56 includes an x-axis driving cylinder 561 and a z-axis driving cylinder 562. The valve cover clamping mechanism 55 is located at the output end of the z-axis driving cylinder 562, and the z-axis driving cylinder 562 is located at the output end of the x-axis driving cylinder 561. The x-axis driving cylinder 561 is fixedly mounted on the frame 1 by a mounting bracket 563. The z-axis driving cylinder 562 is configured as a two-stage stroke cylinder.

[0055] More preferably, the z-axis drive cylinder 562 in the valve cover drive mechanism 56 is a two-stage stroke cylinder, namely a double-acting double-stage telescopic cylinder. After the valve cover is loaded onto the assembly seat, the first stage of the cylinder controls the downward movement, the first valve cover clamp and the second valve cover clamp release the clamp, and the valve cover is installed in the valve seat that has been loaded in the previous process. Then the first valve cover clamp and the second valve cover clamp close, and the second stage of the cylinder continues to extend downward, pressing the valve cover completely into the valve seat, thus completing the loading and assembly of the valve cover.

[0056] More preferably, a limiting cover 521 is provided at the top of the feeding seat 52, and the limiting cover 521 is fastened to the feeding seat 52 to form a valve cover conveying channel. By providing a limiting cover 521 at the top of the feeding seat 52, the valve covers in the conveying process can be limited, and they can be accurately placed into the valve cover receiving groove in the distribution plate through the valve cover conveying channel in sequence.

[0057] After placing the valve seat and steel ball in the assembly base, continue with the valve cover loading process. When the valve cover assembly device 5 is working: the valve cover to be assembled is conveyed from the valve cover feeding vibratory plate 51 to the feeding seat 52, and after passing through the valve cover conveying channel, it enters the valve cover receiving groove 531 set on the distributing plate 53. Under the drive of the distributing drive mechanism 54, the distributing plate 53 and the valve cover on it are pushed to the bottom of the valve cover clamping mechanism 55; the valve cover drive mechanism 56 drives the valve cover clamping mechanism 55 to descend and controls the first valve cover clamping plate 551 and the second valve cover clamping plate 552 to open. When it descends to the position of the valve cover, the first valve cover clamping plate 551 and the second valve cover clamping plate 552 close to clamp and fix the valve cover; under the drive of the valve cover drive mechanism 56, the clamped valve cover is lowered and fed into the assembly seat on the worktable 2. At this time, the valve cover is fed into the valve seat that has been fed; then the first valve cover clamping plate 551 and the second valve cover clamping plate 552 close and descend again to press the valve cover into the valve seat, completing the valve cover feeding and assembly process.

[0058] Based on the above technical solution, the sealing component feeding device includes a gasket feeding device 6, a sealing ring feeding device 7, and a sealing component driving mechanism 8. The gasket feeding device 6 includes a gasket feeding vibratory plate 61, a gasket conveying channel 62, and an adsorption mechanism 63. One end of the gasket conveying channel 62 is connected to the end of the feeding vibratory plate 61, and the other end is located below the adsorption mechanism 63. The adsorption mechanism 63 picks up the gasket 104 and feeds it onto the assembly seat. The sealing ring feeding device 7 includes a sealing ring feeding vibratory plate 71, a sealing ring conveying channel 72, and an internal support clamping mechanism 73. One end of the sealing ring conveying channel 72 is connected to the end of the sealing ring feeding vibratory plate 71, and the other end is located below the internal support clamping mechanism 73. The internal support clamping mechanism 73 is used to feed the sealing ring 105 onto the assembly seat and press it against the outer wall of the valve seat. The sealing component driving mechanism 8 drives the adsorption mechanism 63 and the internal support clamping mechanism 73 to move in different directions along the frame 1.

[0059] More preferably, a position detection switch is provided at the end of the gasket conveying channel 62. By providing a position detection switch, the gasket can be detected in time after it moves to the corresponding position, and then the adsorption mechanism can adsorb and feed it.

[0060] Preferably, both the gasket conveying channel 62 and the sealing ring conveying channel 72 are provided with cover plates at their top ends. By providing cover plates, the positions of the gaskets and sealing rings during the conveying process can be standardized, allowing them to pass through the conveying channels sequentially, avoiding stacked structural components, i.e., only one layer of gaskets or sealing rings is allowed to pass through, and also preventing them from falling off.

[0061] Preferably, the sealing element driving mechanism adopts the same driving mechanism as the valve seat driving mechanism; or corresponding linear modules or ball screw pairs are provided in different directions to drive the adsorption mechanism and the internal support clamping mechanism to move in the up and down and left and right directions.

[0062] Preferably, the adsorption mechanism is configured as a vacuum adsorption disk. The internal support clamping mechanism is a pneumatic gripper, including six grippers that are simultaneously opened or closed by air pressure. When opened outward, it supports and clamps the sealing ring. The sealing element driving mechanism drives the internal support clamping mechanism to move to the assembly position, and then the sealing ring is pushed from the grippers to the valve seat by the pusher block built into the internal support clamping mechanism.

[0063] Preferably, a sealing ring placement platform is provided at the end of the sealing ring conveying channel. The sealing ring placement platform has a limiting groove for accommodating the sealing ring, and a lifting mechanism is provided at the bottom of the sealing ring placement platform, correspondingly positioned below the limiting groove. During conveying, the sealing ring is conveyed from the sealing ring conveying channel to the sealing ring placement platform, where it is located within the U-shaped limiting groove. The lifting mechanism below then lifts the sealing ring, facilitating the removal of the sealing ring by the grippers of the inner support clamping mechanism.

[0064] When the sealing component feeding device is in operation, it follows the feeding and assembly sequence of gaskets first, followed by sealing rings. During gasket feeding and assembly: the gasket is conveyed to the gasket conveying channel 62 via the gasket feeding vibratory feeder 61 until it reaches the area below the adsorption mechanism 63. Under the action of vacuum adsorption, the adsorption mechanism 63 feeds the gasket into the assembly seat on the worktable and assembles it on the outer wall of the valve seat. During sealing ring feeding and assembly, similar to the gasket feeding and assembly, the sealing ring is conveyed to the sealing ring conveying channel 72 via the sealing ring feeding vibratory feeder 71 until it reaches the area below the inner support clamping mechanism 73. The inner support clamping mechanism 73 is activated, and multiple jaws move outward to support and fix the sealing ring. Driven by the sealing component driving mechanism, it is conveyed to the assembly seat, and the built-in pusher block of the inner support clamping mechanism pushes the sealing ring from the jaws onto the valve seat. This completes the feeding and assembly process of the gasket and sealing ring as sealing components.

[0065] It should be noted that the vibratory feeder used in the valve cover assembly device and the seal feeding device is a common feeding component in this industry and can be obtained from the prior art. This application does not improve the specific structure of the vibratory feeder. During the initial feeding and conveying process, the high-frequency micro-amplitude vibration generated by the vibratory feeder drives the material to move forward along the track, and then conveys it to the transfer or clamping position.

[0066] It should be noted that the above-mentioned beginning and end are defined according to the direction of component conveying, and are only for the convenience of describing and understanding this technical solution, and do not constitute a limitation on this application.

[0067] The foregoing has shown and described the basic principles and main features of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments. Therefore, the embodiments should be considered as exemplary and not restrictive. The scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of the equivalents of the claims be included within the present invention.

[0068] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
