Description

Technical Field

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

[0002] Solenoid valves are widely used in the flow paths of various fluids to control the opening and closing of the flow path and the flow rate and velocity of the fluid. The production and assembly of solenoid valves typically includes:

[0003] Industrial assembly at the manufacturing end refers to the process of assembling individual parts (valve body, coil, spindle, spring, seals, etc.) from scratch into a complete solenoid valve in a factory. This requires specialized equipment, tooling, and rigorous quality control.

[0004] On-site assembly using the maintenance end: refers to the process by which users or maintenance personnel connect the purchased complete solenoid valve to the pipeline and circuit when installing or replacing the solenoid valve, or perform simple component replacements (such as coils or seals).

[0005] However, the assembly of the valve body is usually completed before leaving the factory. In the existing assembly process, the solenoid valve is fixed horizontally and the screws are driven horizontally. It is difficult to ensure that the screws are driven in horizontally. In addition, the rear end cap of the solenoid valve needs to be pressed tightly to connect with the valve body, which makes the assembly difficult. Therefore, it is necessary to design a solenoid valve assembly device. Summary of the Invention

Detailed Implementation

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0051] Solenoid valve assembly devices, such as Figure 13 As shown, the solenoid valve 9 includes a valve body 91. A front end assembly is fixedly provided at one end of the valve body 91, and a rear end cover 93 is fixedly provided at the other end. An air passage port 92 is provided on the valve body 91. A washer 94 and a screw 95 are installed on the rear end cover 93. The screw 95 passes through the washer 94 and connects the rear end cover 93 to the valve body 91. Then, the front end assembly is connected to the valve body 91 to complete the finished product.

[0052] like Figures 1-3As shown, the assembly device includes a pneumatic indexing plate 1, which carries the valve body 91 to rotate and switch work positions. The assembly device also includes a material picking mechanism 1 2, an assembly mechanism 1 3, a material picking mechanism 2 4, an assembly mechanism 2 5, a screw driving mechanism 6, and a material unloading mechanism 7, which are located on the outside of the pneumatic indexing plate 1.

[0053] The aforementioned material picking mechanism 1, assembly mechanism 1, material picking mechanism 2, assembly mechanism 2, screw driving mechanism 6, and unloading mechanism 7 are arranged in sequence along the circumference of the pneumatic indexing plate 1. Among them, material picking mechanism 2, assembly mechanism 2, and screw driving mechanism 6 are set as two groups, which respectively assemble the two sets of washers 94 and screws 95 on the rear end cover 93.

[0054] The assembly device also includes several feeding trays, wherein feeding tray 10 is located on one side of feeding mechanism 2 and is used to feed valve body 91, feeding tray 200 is located on one side of feeding mechanism 4 and is used to feed gasket 94, and feeding tray 301 is located on one side of screw-driving mechanism 6 and is used to feed screw 95.

[0055] All of the above-mentioned feeding trays are vibrating feeding trays, which are existing technologies and will not be described in detail.

[0056] The unloading mechanism 7 is located between the first material picking mechanism 2 and the last screw-driving mechanism 6. It is used to clamp and unload the valve body 91 with the rear end cover 93 assembled. The unloading mechanism 7 includes a hydraulic cylinder 1 horizontally set above the pneumatic indexing plate 1. A second hydraulic cylinder 71 is fixedly installed at the output end of the first hydraulic cylinder. The first hydraulic cylinder controls the second hydraulic cylinder 71 to move horizontally. A material picking clamp 72 is fixedly connected to the output end of the second hydraulic cylinder 71. The second hydraulic cylinder 71 controls the material picking clamp 72 to clamp the valve body 91 on the pneumatic indexing plate 1 to complete the unloading operation.

[0057] like Figure 2 As shown, a material distribution component is provided at the discharge end of the feeding tray. The material distribution component includes a material distribution plate 81 that slides on the discharge end of the feeding tray. The assembly device also includes several cylinders 80. The output end of the cylinders 80 is fixedly connected to one end of the material distribution plate 81. A material distribution groove 82 is provided on the material distribution plate 81. The material distribution groove 82 is set with different shapes to match the valve body 91, gasket 94, and screw 95.

[0058] Taking the valve body 91 in the feeding tray 10 as an example, when a valve body 91 enters the corresponding distribution groove 82, the cylinder 80 pushes the distribution plate 81 to move horizontally, and the distribution groove 82 moves to the material picking position of the material picking mechanism 2. The distribution groove 82 is misaligned with the discharge position of the feeding tray 10, preventing the feeding of subsequent valve bodies 91. After the material picking mechanism 2 removes the valve body 91 from the distribution groove 82, the distribution groove 82 is reset to the discharge position of the feeding tray 10 for subsequent replenishment and feeding operations.

[0059] like Figures 2-5 As shown, the material handling mechanism 12 includes a slide table 21. A cylinder 22 is fixedly installed at one end of the slide table 21. The output end of the cylinder 22 is connected to a slide block. The slide block is located on one side of the slide table 21 and slides horizontally. A cylinder 33 is fixedly installed on the slide block. A pneumatic clamp 24 is fixedly installed at the output end of the cylinder 33. The pneumatic clamp 24 is used to remove the valve body 91 from the material distribution groove 82 and place it in the fixture 11 on the pneumatic indexing plate 1.

[0060] like Figure 6 As shown, a pneumatic indexing plate 1 is fixedly provided with an array of fixtures 11. The fixtures 11 are provided with mounting grooves 12, and the bottom of the mounting grooves 12 penetrates the fixtures 11. A stand 13 is fixedly provided on the pneumatic indexing plate 1. A cylinder 14 is fixedly provided on the stand 13. A valve 15 is fixedly connected to the output end of the cylinder 14. A connecting pipe is fixedly provided at one end of the valve 15. A horizontal nozzle 16 and a vertical nozzle 17 are respectively provided at both ends of the connecting pipe. The horizontal nozzle 16 is located on one side of the fixture 11, and the vertical nozzle 17 is located below the mounting grooves 12.

[0061] The cylinder 14 controls the vertical movement of the valve 15 and the connecting pipe, adjusts the two air nozzles to align with the valve body 91, blows air into the air passage port 92 through the horizontal air nozzle 16 to remove dust, and removes dust from the end of the valve body 91 where the front-end component is installed through the vertical air nozzle 17, and then unloads the material. The stand 13 is located between the unloading mechanism 7 and the last screw-driving mechanism 6.

[0062] like Figure 5 As shown, the material handling mechanism 2 4 includes a cylinder 5 installed on the outside of the pneumatic indexing plate 1. The output end of the cylinder 5 is fixedly connected to a rotary motor 41 to control the vertical movement of the rotary motor 41 and its components, adjust the material handling height, and facilitate the material handling operation. The output end of the rotary motor 41 is fixedly connected to a pneumatic clamp 2 42, and the output end of the pneumatic clamp 2 42 is provided with a gripper for gripping the washer 94.

[0063] The gripper removes the washer 94 from the material distribution component corresponding to the discharge end of the feeding tray 2100.

[0064] Assembly mechanism 2 5 includes cylinder 6 51 located above the pneumatic indexing plate 1. Assembly mechanism 2 5 is configured as two cylinders, with the output end of cylinder 6 51 facing the fixture 11 on the pneumatic distribution plate 1. The output ends of the two cylinders 6 51 are aligned with the two holes at the end of the rear cover 93 that require screws.

[0065] A connecting rod 52 is fixedly provided at the output end of cylinder 6 51, and a mounting ring 53 is fixedly provided at the end of the connecting rod 52, such as... Figures 7-9As shown, a groove 54 is fixedly provided inside the mounting ring 53, and a support frame 55 is installed inside the groove 54. An array of limiting shafts 56 are fixedly provided at the outer end of the support frame 55. The limiting shafts 56 are horizontally arranged and perpendicular to the telescopic rod 571.

[0066] A sleeve 57 is fixedly installed in the middle of the slot 54. A spring 572 is fixedly installed on the outside of the sleeve 57. The spring 572 is fixedly connected to the outside of the telescopic rod 571 which is slidably installed in the sleeve 57. A conical block 573 is fixedly installed at the end of the telescopic rod 571 away from the sleeve 57. An array of swing rods 574 are rotatably installed at the end of the conical block 573 where it connects with the telescopic rod 571. The swing rods 574 are correspondingly set with the limiting shaft 56.

[0067] A through groove 575 is provided in the middle of the swing rod 574. The through groove 575 is slidably connected to the limiting shaft 56. A groove is provided at the end of the swing rod 574 away from the conical block 573. A pressure shaft 576 parallel to the limiting shaft 56 is provided in the groove. An array of mounting tubes 59 are fixed on the mounting ring 53. A second spring 583 is fixedly provided in the mounting tube 59. A thin rod 582 is fixedly connected to the end of the second spring 583. A pressure rod 58 is fixedly provided at the end of the thin rod 582 away from the second spring 583. A diagonal rod 581 is fixedly provided at one end of the pressure rod 58. The upper part of the diagonal rod 581 is slidably connected to the pressure shaft 576.

[0068] When cylinder 6 51 pushes connecting rod 52 toward the two screw holes at the end of rear cover 93, conical block 573 contacts the bottom of the hole in valve body 91. As connecting rod 52 continues to press down, conical block 573 acts and compresses spring 1 572. During this process, the upper end of rocker arm 574 moves outward under the limit of limit shaft 56, contacting the inner side of washer 94. This corrects the position of washer 94 with the screw holes, preventing washer 94 from becoming misaligned. As the lever 574 moves outward, the inclined rod 581 is pressed down, causing the lower side of the pressure rod 58 to contact the washer 94, pressing the washer 94 onto the rear cover 93 to prevent jamming between the washer 94 and the lever 574. After the cylinder 6 51 retracts to the output end, the spring 1 572 gradually recovers its deformation, and the ends of several levers 574 that are in contact with the washer 94 gradually move closer together. Then the conical block 573 is removed, and the valve body 91 moves with the pneumatic indexing plate 1 to the screw-driving mechanism 6.

[0069] There are two screw-driving mechanisms 6. The screw-driving mechanism 6 includes a horizontally arranged cylinder 7 60. The output end of cylinder 7 60 is fixedly connected to a cylinder 8 61 arranged parallel to cylinder 6 51. The output end of cylinder 8 61 is fixedly connected to a mounting plate 62. An automatic screw-locking mechanism 63 is fixedly installed on the mounting plate 62. The automatic screw-locking mechanism 63 can be the screw-driving part of an existing automatic screw machine, such as the LX-S100 screw machine.

[0070] Cylinder 7 60 and cylinder 8 61 control the horizontal and vertical movement of the automatic screw-locking mechanism 63, so that the automatic screw-locking mechanism 63 can take the screw 95 from the corresponding material distribution component set at the discharge end of the feeding tray 3 101 and assemble it into the hole on the rear cover 93 where the washer 94 is installed.

[0071] like Figures 10-12 As shown, the assembly mechanism 3 includes a stand 31, a movable seat 32 is slidably mounted on the stand 31, and a cylinder 33 is fixedly mounted below the movable seat 32. The output end of the cylinder 33 is fixedly connected to the top of the stand 31. By retracting the output end of the cylinder 33, the height of the movable seat 32 is raised, and vice versa, the height of the movable seat 32 is lowered.

[0072] A central shaft 341 is fixedly provided on one side of the movable base 32. A rotating arm 35 is rotatably provided on the central shaft 341. An arc-shaped groove 34 coaxial with the central shaft 341 is provided below the central shaft 341. A movable shaft 36 is slidably provided in the arc-shaped groove 34. One end of the movable shaft 36 is fixedly connected to one end of the rotating arm 35. A mounting part 37 is fixedly provided at the other end of the rotating arm 35.

[0073] A servo motor 371 is fixedly mounted on the back side of the mounting part 37. A gear 372 is fixedly mounted on the output end of the servo motor 371. A rack 373 meshes with both sides of the gear 372. A clamping block 374 is fixedly mounted on one end of the rack 373. A clamping groove 375 is opened on the inner side of the clamping block 374. If the rear end cover 93 is rectangular, the clamping block 374 clamps the rear end cover 93. If the rear end cover 93 is circular or other shapes, the side of the rear end cover 93 is limited and clamped by the clamping groove 375.

[0074] A guide rod 376 is fixedly provided on the outer side of the clamping block 374. The guide rod 376 is slidably connected to the mounting part 37. A cylinder 38 is fixedly provided on one side of the mounting part 37. A pressure plate 381 is fixedly provided at the output end of the cylinder 38. When the clamping block 374 places the rear end cover 93 on the valve body 91, the pressure plate 381 presses down on the rear end cover 93, so that the rear end cover 93 is connected to the valve body 91, and then the first washer 94 is assembled.

[0075] A horizontally positioned cylinder 11 39 is fixedly installed on one side of the movable base 32. A slotted plate 391 is fixedly installed at the output end of the cylinder 11 39. The slotted plate 391 is slidably connected to the movable shaft 36. A spring 392 is fixedly installed on the slotted plate 391. The upper end of the spring 392 abuts against the side of the movable shaft 36. The cylinder 11 39 pulls the slotted plate 391 to move horizontally, thereby driving the movable shaft 36 to slide in the arc-shaped groove 34, thereby controlling the rotation of the rotating arm 35 and adjusting the rotation of the mounting part 37 and the clamping block 374 on it.

[0076] When clamping block 374 is located as follows Figure 12The rear end cover 93 is loaded into the state shown. After the rear end cover 93 is clamped by the clamping block 374, the clamping block 374 is adjusted and rotated to move the rear end cover 93 above the pneumatic indexing plate 1. The height of the clamping block 374 is lowered by the cylinder 93, so that the rear end cover 93 is installed on the valve body 91. The rear end cover 93 is pressed down by the cylinder 1038, thereby realizing the assembly of the rear end cover 93 and the valve body 91.

[0077] During use, the valve body 91 is picked up and placed onto the fixture 11 by the material picking mechanism 1. The pneumatic indexing plate 1 is started to send the valve body 91 into each station in sequence. First, the rear end cover 93 is assembled onto the valve body 91 by the assembly mechanism 1 3. Then, the washer 94 is placed into a hole of the rear end cover 93 by the material picking mechanism 2 4. Then, the washer 94 is positioned and pressed by the assembly mechanism 2 5. Finally, the screw assembly of the hole is completed by the first screw-driving mechanism 6.

[0078] Then, after passing through the next material handling mechanism 24 and assembly mechanism 25, the washer 94 on another hole is assembled and pressed. Then, after passing through the second screw-driving mechanism 6, the screws are assembled. Finally, after passing through the dust removal station, the valve body 91 is dusted by the horizontal air nozzle 16 and the vertical air nozzle 17. Finally, the product is removed by the unloading mechanism 7.

[0079] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
