Description

Technical Field

[0001] This invention relates to the field of solenoid valve manufacturing technology, and specifically to a solenoid valve core manufacturing and processing device. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation used to control fluids. They are actuators, not limited to hydraulic or pneumatic systems. Used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. The valve core of a solenoid valve is the core actuator that realizes fluid flow control and reversal. Its structure, material, and operating method directly determine the solenoid valve's response speed, sealing performance, lifespan, and adaptability to operating conditions. The sealing ring installed on the surface of the valve core is a core vulnerable component that ensures sealing between the valve core, valve sleeve, and valve seat, guaranteeing the accuracy and sealing of fluid control in the valve assembly. Its core function is to block unexpected fluid pathways, while also ensuring the smoothness of valve core movement and adaptability to operating conditions. Specific functions can be categorized into three types: core sealing, auxiliary protection, and operating condition adaptation. Furthermore, the emphasis of the sealing ring may slightly differ depending on the valve core structure.

[0003] In the current technology, in order to reduce production costs, the valve core of a solenoid valve is still manufactured manually by installing the sealing ring on the surface of the valve core. This manual assembly of the valve core and the sealing ring presents several problems: (1) The valve core and sealing ring of the solenoid valve require extremely high precision in their fit. Manual assembly makes it difficult to accurately control the installation position and force, which may lead to poor sealing or obstruction of valve core movement, affecting the performance and reliability of the solenoid valve. (2) Furthermore, manual assembly is slow and cannot meet the needs of large-scale production. In cases requiring high-precision assembly, the speed and accuracy of manual operation will be limited, resulting in low production efficiency. (3) During manual assembly, the operator's hands may carry contaminants such as grease and dust, which may enter the solenoid valve and affect its performance and lifespan. In addition, manual operation may introduce foreign objects, such as hair and fibers, which may further affect the sealing and reliability of the solenoid valve. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a solenoid valve core manufacturing and processing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A solenoid valve core manufacturing and processing device includes a processing table and a base. The processing table is located on top of the base. Multiple circular grooves are formed inside the processing table, and cylinders for placing valve cores are rotatably installed inside each of the grooves. Each cylinder has a limit mechanism inside.

An assembly mechanism for automatically fitting sealing rings onto the valve core surface is located on the side of the fixing frame closest to the processing table. An mounting frame is installed at the center of the top of the processing table. Multiple cleaning mechanisms, the same number as the cylinders, are installed on the outer wall of the mounting frame. Multiple fixing blocks, the same number as the cylinders, are installed on the top of the processing table. Each fixing block has a detection mechanism at its top for inspecting the surface quality of the valve core.

[0006] Optionally, a first motor is installed on the top of the base, and the output end of the first motor is connected to the center of the bottom of the processing table. The top of the base is also equipped with multiple mounting plates, the same number as the cylinders. Each mounting plate has a discharge pipe installed inside, and the top of each discharge pipe abuts against the bottom of the corresponding cylinder.

[0007] Optionally, the limiting mechanism includes two rotating blocks rotatably mounted on the inner wall of the cylinder. The top of each of the two rotating blocks at one end close to each other is provided with a semi-circular placement groove. After the two placement grooves are connected, they form a circular groove for placing the valve core. The inner wall of the cylinder is also equipped with two first electric telescopic rods. The telescopic ends of the two first electric telescopic rods are equipped with limiting plates. Multiple cylinders are rotatably connected to the inner wall of the circular groove through the first rotating part provided on the outer wall.

[0008] Optionally, the driving mechanism includes a fixed plate installed at the bottom of the processing table, a second motor installed at the top of the fixed plate, a gear installed at the output end of the second motor, a rotating groove opened at the bottom of the processing table, a second rotating part rotatably installed inside the rotating groove, a first toothed ring installed at the bottom of the second rotating part, transmission teeth provided on both the inner and outer walls of the first toothed ring, the transmission teeth on the inner wall of the first toothed ring meshing with the gear, and second toothed rings installed on the outer walls of the bottom of multiple cylinders, the multiple second toothed rings meshing with the transmission teeth on the outer walls of the first toothed ring.

[0009] Optionally, the assembly mechanism includes a first groove on the outer wall of the fixed frame near the processing table, a lead screw rotatably mounted inside the first groove, a third motor mounted on the top of the fixed frame, the output end of the third motor connected to the top of the lead screw, a movable seat threaded onto the outer wall of the lead screw, and an assembly head mounted on the end of the movable seat away from the lead screw.

[0010] Optionally, the cleaning mechanism includes a plurality of first sliding grooves opened on the outer wall of the mounting frame, a first slider installed inside each of the plurality of first sliding grooves, a first moving block installed at the end of each of the plurality of first sliders away from the first sliding grooves, a second sliding groove opened at the top of each of the plurality of first moving blocks, a second slider installed inside each of the plurality of second sliding grooves, and a second moving block installed at the top of each of the plurality of second sliders.

[0011] Optionally, a second groove is provided on one side of the outer wall of the second movable block, and a double-ended screw is rotatably installed inside the second groove. Two rectangular strips are threadedly installed on the outer wall of the double-ended screw, and a cleaning block is installed on the outer wall of the side of the two rectangular strips that are close to each other.

[0012] Optionally, a housing is installed on the top of the second movable block, and two hoses are installed on the side of the housing near the two rectangular plates. The ends of the two hoses away from the housing are connected to the cleaning blocks nearby. A blower head is rotatably installed on the ends of the two rectangular plates away from the double-headed screw.

[0013] Optionally, the detection mechanism includes a third slide groove opened at the top of the fixed block, a third slider installed inside the third slide groove, a rectangular block rotatably mounted at the top of the third slider, and an industrial camera mounted on the outer wall of the rectangular block near the cylinder.

[0014] Optionally, the rectangular block is hollow inside, and the interior of the rectangular block stores lubricating oil. The outer wall of the rectangular block away from the cylinder is connected to a hollow plate through a telescopic pipe. An oil-absorbing pad is installed on the outer wall of the hollow plate away from the rectangular block. Multiple second electric telescopic rods are installed inside the rectangular block, and the telescopic ends of the multiple second electric telescopic rods are all connected to the hollow plate.

[0015] The beneficial effects of this invention are: 1. In this invention, by setting a rotating processing table and an assembly mechanism, multiple valve cores can be placed inside the corresponding cylinders. With the help of the processing table, the multiple valve cores are rotated sequentially to the bottom of the assembly mechanism, so that the assembly mechanism can automatically assemble the sealing ring and the valve core, avoiding many drawbacks of manual assembly and improving the assembly efficiency of the valve core and the sealing ring.

[0016] 2. In this invention, before the assembly mechanism assembles the valve core and the sealing ring, the cleaning mechanism cleans the sealing ring mounting area of ​​the valve core to avoid manual assembly, which can easily lead to dust accumulation on the sealing ring mounting area of ​​the valve core, resulting in a gap between the sealing ring and the valve core, thus affecting the sealing performance of the solenoid valve.

[0017] 3. In this invention, after the sealing ring mounting part of the valve core is cleaned, the rectangular block at the corresponding position of the valve core can be controlled to rotate 180 degrees, driving the hollow plate and oil suction pad to rotate to a position close to the valve core. Then, the third slider is controlled to move and adjust in the third slide groove towards the valve core, and the extension ends of multiple second electric telescopic rods are controlled to extend together, pushing the oil suction pad to abut against the sealing ring mounting part of the valve core. At this time, the valve core can still be driven to rotate synchronously with the help of the cylinder, so that the oil suction pad can evenly apply lubricating oil to the surface of the sealing ring mounting part of the valve core, so that the sealing ring can be quickly fitted onto the surface of the valve core.

[0018] 4. In this invention, after the assembly of the valve core and the sealing ring is completed, as the processing table continues to rotate, the assembled valve core rotates and resets to the front of the device. At this time, in order to facilitate the subsequent storage of the valve core and the assembly with other components, it is necessary to protect the part of the valve core with the sealing ring installed to prevent the sealing ring from being damaged during the storage process. At this time, the heat shrink film can be manually or with the help of a preset robotic arm to put on the top of the valve core. Then, the second slider is controlled to move towards the valve core inside the second slide groove, driving the two blowers to move to both ends of the heat shrink film. As the two blowers blow hot air onto the heat shrink film, the bottom end of the heat shrink film slowly shrinks to a state of adhering to the outer wall of the valve core, so that the heat shrink film can be effectively put on the surface of the valve core, protecting the installed sealing ring and ensuring that the subsequent storage and assembly of the valve core are not affected.

[0022] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Reference Figures 1-13A solenoid valve core manufacturing and processing device includes a processing table 1 and a base 2. The processing table 1 is located on top of the base 2. The processing table 1 has multiple circular grooves 20 inside. Each of the multiple circular grooves 20 has a cylinder 6 for placing the valve core rotatably installed inside. Each of the multiple cylinders 6 has a limit mechanism inside. The bottom end of the processing table 1 is provided with a drive mechanism for driving the multiple cylinders 6 to rotate and adjust inside the corresponding circular grooves 20. A fixing frame 3 is installed on one side of the base 2. The side of the fixing frame 3 near the processing table 1 is provided with an assembly mechanism for automatically fitting the sealing ring onto the surface of the valve core. A mounting frame 7 is installed at the center of the top of the processing table 1. The outer wall of the mounting frame 7 is provided with multiple cleaning mechanisms equal to the number of cylinders 6. Multiple fixing blocks 10 equal to the number of cylinders 6 are installed on the top of the processing table 1. Each of the multiple fixing blocks 10 has a detection mechanism for detecting the surface quality of the valve core.

[0024] As a technical optimization of the present invention, a first motor is installed on the top of the base 2, and the output end of the first motor is connected to the bottom center of the processing table 1. Multiple mounting plates 11, the same number as the cylinders 6, are also installed on the top of the base 2. Each mounting plate 11 has a discharge pipe 5 installed inside, and the top ends of the discharge pipes 5 abut against the bottom ends of the corresponding cylinders 6. After starting, the first motor can drive the processing table 1 to rotate and adjust on the top of the base 2.

[0025] As a technical optimization of the present invention, the limiting mechanism includes two rotating blocks 24 rotatably mounted on the inner wall of the cylinder 6. A semi-circular placement groove 25 is formed at the top of each of the two rotating blocks 24 at their adjacent ends. The two placement grooves 25, when aligned, form a circular groove for placing the valve core. Two first electric telescopic rods 23 are also installed on the inner wall of the cylinder 6. Limiting plates 22 are installed at the telescopic ends of the two first electric telescopic rods 23. Multiple cylinders 6 are rotatably connected to the inner wall of the circular groove 20 via first rotating parts 19 provided on the outer wall. Two first driving devices are preset on the inner wall of the cylinder 6. The output ends of the two first driving devices are respectively connected to the rotating parts of one end of the corresponding rotating block 24, thereby enabling the two rotating blocks 24 to rotate and adjust inside the cylinder 6. During the telescopic process of the two first electric telescopic rods 23, they can drive the corresponding limiting plates 22 to move towards or away from each other, so that after the two limiting plates 22 move towards each other, they can clamp and fix the valve core placed inside the placement groove 25.

[0026] As an optimized technical solution of the present invention, the driving mechanism includes a fixed plate 15 installed at the bottom of the processing table 1. A second motor 16 is installed at the top of the fixed plate 15, and a gear 17 is installed at the output end of the second motor 16. A rotating groove 18 is opened at the bottom of the processing table 1, and a second rotating part 19 is rotatably installed inside the rotating groove 18. A first gear ring 12 is installed at the bottom of the second rotating part 19. Both the inner and outer walls of the first gear ring 12 are provided with transmission teeth. The transmission teeth on the inner wall of the first gear ring 12 mesh with the gear 17. A second gear ring 13 is installed on the outer wall of the bottom of a plurality of cylinders 6, and the plurality of second gear rings 13 mesh with the transmission teeth on the outer wall of the first gear ring 12. After the second motor 16 is started, it can drive the gear 17 to rotate synchronously, thereby driving the first gear ring 12 to rotate at the bottom of the processing table 1. Since the transmission teeth on the outer wall of the first gear ring 12 mesh with the plurality of second gear rings 13, the plurality of second gear rings 13 and their corresponding cylinders 6 can be driven to rotate and adjust together.

[0027] As an optimized technical solution of the present invention, the assembly mechanism includes a first groove on the outer wall of the fixed frame 3 near the processing table 1. A lead screw 14 is rotatably mounted inside the first groove. A third motor is mounted on the top of the fixed frame 3, and the output end of the third motor is connected to the top of the lead screw 14. A movable seat is threaded onto the outer wall of the lead screw 14, and an assembly head 4 is mounted on the end of the movable seat away from the lead screw 14. After the third motor is started, it can drive the lead screw 14 to rotate inside the first groove, thereby driving the movable seat and the assembly head 4 to move up and down together, so that the assembly head 4 can automatically fit the sealing ring into the designated position of the valve core.

[0028] As an optimized technical solution of the present invention, the cleaning mechanism includes multiple first slide grooves 8 formed on the outer wall of the mounting frame 7. Each of the multiple first slide grooves 8 has a first slider 26 installed inside it. Each of the multiple first sliders 26 has a first moving block 9 installed at the end furthest from the first slide groove 8. Each of the multiple first moving blocks 9 has a second slide groove 27 at its top. Each of the multiple second slide grooves 27 has a second slider 31 installed inside it. Each of the multiple second sliders 31 has a second moving block 28 installed at its top. Each of the multiple first slide grooves 8 has a pre-installed first linear motor, which can drive the multiple first sliders 26 to move up and down together within their respective first slide grooves 8, thereby causing the multiple first moving blocks 9 to move up and down on the top of the processing table 1 for adjustment. Similarly, each of the multiple second slide grooves 27 has a pre-installed second linear motor, which can drive the multiple second sliders 31 to move back and forth within their respective second slide grooves 27, thereby causing the multiple second moving blocks 28 to move back and forth on the top of their respective first moving blocks 9 for adjustment.

[0029] As a technical optimization of the present invention, a second groove is formed on one outer wall of the second moving block 28. A double-ended screw 35 is rotatably installed inside the second groove. Two rectangular strips 29 are threaded onto the outer wall of the double-ended screw 35. Cleaning blocks 34 are installed on the outer walls of the two rectangular strips 29 that are close to each other. A second driving device is preset on one outer wall of the second moving block 28. The output end of the second driving device is connected to one end of the double-ended screw 35, thereby driving the double-ended screw 35 to rotate inside the second groove. This, in turn, drives the two rectangular strips 29 to move and adjust in a direction that is closer or farther apart, so as to synchronously drive the two cleaning blocks 34 to move and adjust together.

[0030] As a technical optimization of the present invention, a housing 32 is installed on the top of the second moving block 28. Two hoses 33 are installed on the side of the housing 32 near the two rectangular strips 29. The ends of the two hoses 33 away from the housing 32 are connected to the cleaning block 34 that is close to them. A blower head 30 is rotatably installed on the ends of the two rectangular strips 29 away from the double-headed screw 35. Both housings 32 contain alcohol or other volatile cleaning agents, which are delivered to two cleaning blocks 34 via two hoses 33. The cleaning agents absorbed by the blocks 34 then come into contact with the sealing ring mounting area of ​​the valve core, cleaning this area and ensuring better performance of the subsequently installed sealing ring. A third drive device is pre-installed on the top of each of the two rectangular plates 29. The output of each third drive device is connected to the rotating part at the top of the corresponding blower head 30, allowing the blower head 30 to rotate and adjust at one end of the rectangular plate 29. Both blower heads 30 are connected to an externally pre-installed hot air blower via pipes, allowing them to exhaust hot air during use.

[0031] As a technical optimization of the present invention, the detection mechanism includes a third slide groove 36 opened at the top of the fixed block 10. A third slider 37 is installed inside the third slide groove 36, and a rectangular block 38 is rotatably mounted at the top of the third slider 37. An industrial camera 39 is installed on the outer wall of the rectangular block 38 near the cylinder 6. A third linear motor is preset inside the third slide groove 36, which can drive the third slider 37 to move back and forth inside the corresponding third slide groove 36, thereby driving the rectangular block 38 to move and adjust at the top of the fixed block 10. A fourth driving device is preset inside the third slider 37, and the output end of the fourth driving device is connected to the rotating part at the bottom of the rectangular block 38, thereby driving the rectangular block 38 to rotate and adjust at the top of the third slider 37. The industrial camera 39 is a KEYENCE CV-X series vision camera in the prior art.

[0032] As a technical optimization of the present invention, the rectangular block 38 is hollow inside and stores lubricating oil. A hollow plate 40 is connected to the outer wall of the rectangular block 38 away from the cylinder 6 via a retractable pipe 42. An oil-absorbing pad 41 is installed on the outer wall of the hollow plate 40 away from the rectangular block 38. Multiple second electric telescopic rods 43 are installed inside the rectangular block 38, and the telescopic ends of the multiple second electric telescopic rods 43 are all connected to the hollow plate 40. The lubricating oil inside the rectangular block 38 can be transported to the interior of the hollow plate 40 through the pipe 42 and discharged into the oil-absorbing pad 41 through a discharge port at the end of the hollow plate 40 away from the rectangular block 38 for temporary absorption. This allows the telescopic ends of the multiple second electric telescopic rods 43 to extend, pushing the oil-absorbing pad 41 to contact the sealing ring mounting position of the valve core, thus lubricating the sealing ring mounting position on the valve core surface. This facilitates faster installation of the sealing ring at the designated position and reduces wear during installation.

[0033] In this invention, when the user uses the device, the worker stands in front of the device or a loading robot is pre-installed in front of the device. The valve core that needs to be assembled into a sealing ring is placed inside one of the cylinders 6, so that the bottom end of the valve core falls into the placement groove 25. Then, the extension ends of the two first electric telescopic rods 23 are extended together, driving the two limiting plates 22 to clamp and fix the valve core placed inside the cylinder 6. Then, the first motor is controlled to drive the processing table 1 to slowly rotate clockwise, driving the next cylinder 6 to rotate to the vicinity of the loading robot or the worker. Then, the next valve core is placed in the corresponding cylinder 6 manually or by the loading robot, and fixed by the limiting mechanism, so as to achieve the effect of continuous loading of multiple valve cores to be assembled.

[0034] As the processing table 1 continues to rotate clockwise, before the cylinder 6 containing the valve core rotates to the gap directly below the assembly mechanism, the drive mechanism at the bottom of the processing table 1 can be controlled to drive multiple cylinders 6 to rotate and adjust together in the corresponding circular groove 20, causing the valve core to rotate together. At this time, the third slider 37 of multiple detection mechanisms can be controlled to move towards the cylinder 6, driving the industrial camera 39 to identify and detect the sealing ring to be installed on the valve core top. If burrs or other defects are detected on the sealing ring to be installed on the valve core, in order not to affect the subsequent installation of the sealing ring, the telescopic ends of the two first electric telescopic rods 23 can be directly controlled to retract to their original positions, and the two rotating blocks 24 inside the cylinder 6 can be controlled to rotate downwards together, so that the valve core placed in the placement groove 25 falls downwards and slides out into the discharge pipe 5 below, achieving the effect of automatically rejecting such defective valve cores.

[0035] After the valve core passes the inspection by the industrial camera 39, the second slider 31 can be controlled to move closer to the valve core inside the corresponding second slide groove 27. This moves the second moving block 28 and the two rectangular strips 29 together until the parts of the two rectangular strips 29 with the cleaning blocks 34 are moved to a position that matches the valve core. Then, the double-headed screw 35 is controlled to move the two rectangular strips 29 and the cleaning blocks 34 closer together until the two cleaning blocks 34 abut against the outer wall of the valve core. At this point, the cylinder 6 is used to rotate and adjust the valve core, so that the two cleaning blocks 34 can clean the part of the valve core where the sealing ring is to be installed. This prevents dust from being present on the sealing ring installation part of the valve core, which could cause a gap between the sealing ring and the valve core, thus affecting the sealing performance of the solenoid valve.

[0036] Since each of the two rectangular strips 29 is equipped with a blower head 30 near one end of the cylinder 6, after the two cleaning blocks 34 have cleaned the sealing ring mounting area of ​​the valve core, as the second slider 31 slides and resets in the corresponding second slide groove 27, the two blower heads 30 are positioned close to the valve core. The two blower heads 30 are controlled to rotate and adjust towards the valve core, and the external preset hot air blower is started. The two blower heads 30 can then blow hot air towards the valve core, accelerating the drying of the volatile cleaning agent on its surface and assisting in further cleaning the sealing ring mounting area of ​​the valve core. This ensures that the sealing ring mounting area of ​​the valve core has a high degree of cleanliness and will not affect the subsequent assembly of the sealing ring.

[0037] After the sealing ring mounting area of ​​the valve core is cleaned, the rectangular block 38 at the corresponding position of the valve core can be rotated 180 degrees, driving the hollow plate 40 and the oil suction pad 41 to rotate to a position close to the valve core. Then, the third slider 37 is controlled to move and adjust in the direction close to the valve core inside the third slide groove 36, and the extension ends of multiple second electric telescopic rods 43 are controlled to extend together, pushing the oil suction pad 41 to move to abut against the sealing ring mounting area of ​​the valve core. At this time, the valve core can still be rotated synchronously with the help of the cylinder 6, so that the oil suction pad 41 can evenly apply lubricating oil to the surface of the sealing ring mounting area of ​​the valve core, so that the sealing ring can be quickly fitted onto the surface of the valve core.

[0038] After the above-mentioned surface quality inspection, cleaning, and lubrication of the valve core are completed, the valve core rotates to the bottom of the assembly mechanism. The assembly head 4 is driven downward by the lead screw 14, so that after the assembly head 4 comes into contact with the valve core, it retracts through the telescopic part at the bottom of the assembly head 4, allowing the top of the valve core to move into the interior of the assembly head 4. The sealing ring pre-placed inside the assembly head 4 can then be fitted onto the designated installation position on the surface of the assembly head 4, thus completing the automated continuous assembly of the valve core and sealing ring, improving the assembly efficiency of large batches of valve cores and sealing rings.

[0039] After the valve core and sealing ring are assembled, as the processing table 1 continues to rotate, the assembled valve core rotates and resets to the front of the device. At this time, in order to facilitate the subsequent storage of the valve core and the assembly with other components, it is necessary to protect the part of the valve core with the sealing ring installed to prevent the sealing ring from being damaged during the storage process. At this time, the heat shrink film can be manually or with the help of a preset robotic arm to put on the top of the valve core. Then, the second slider 31 is controlled to move inside the second slide groove 27 towards the valve core, driving the two blowers 30 to move to both ends of the heat shrink film. As the two blowers 30 blow hot air onto the heat shrink film, the bottom end of the heat shrink film slowly shrinks to a state of adhering to the outer wall of the valve core, so that the heat shrink film can be effectively put on the surface of the valve core to protect the installed sealing ring and ensure that the subsequent storage and assembly of the valve core are not affected.

[0040] Since the two blowers 30 can be rotated and adjusted at the ends of the corresponding rectangular strips 29, after the assembly of a batch of valve cores and sealing rings is completed, multiple second sliders 31 can be controlled to move towards the cylinder 6 inside the corresponding second slide grooves 27, and multiple third sliders 37 can be controlled to move towards the cylinder 6 inside the corresponding third slide grooves 36. Then, multiple blowers 30 can be controlled to rotate and adjust at the ends of the corresponding rectangular strips 29 so that all blowers 30 face the industrial camera 39. At this time, the room temperature air force discharged by multiple blowers 30 can blow away and clean the impurities attached to the surface of the industrial camera 39, so that the industrial camera 39 can better detect the surface quality of the valve core.
