Description

Technical Field

[0001] This invention relates to the field of solenoid valve assembly technology, and more specifically to a feeding fixture for a rotary solenoid valve assembly production line. Background Technology

[0002] A solenoid valve is an industrial device that uses electromagnetic force to control the flow of fluids. As a fundamental component of automation systems, it is primarily responsible for controlling the direction, flow rate, and velocity of liquids or gases. The solenoid valve has a precision internal thread structure, and the cleanliness of this thread directly determines the valve's assembly sealing performance, fitting accuracy, and overall operational stability, making it a key factor in ensuring product yield. Currently, mass production of solenoid valves commonly employs multi-station rotary assembly lines, equipped with feeding fixtures for sorting, conveying, and positioning valve bodies, providing precise station references for subsequent assembly operations.

[0003] Existing traditional feeding fixtures have a single function, only limiting and conveying the valve body's external contour. They only have basic functions of workpiece feeding, positioning, and transfer, and cannot perform simultaneous cleaning of the internal threads during valve body feeding. After the valve body is machined, the internal thread grooves and blind holes are prone to residual metal shavings, oil stains, and fine burrs. The industry can only rely on pre-positioned offline ultrasonic cleaning or manual air blowing for cleaning, which is disconnected from the feeding and assembly processes. This method not only has problems with cleaning blind spots and incomplete chip removal, but also easily generates secondary dust adhesion during the transfer and loading process after valve body cleaning. Furthermore, there is no online cleaning compensation method, which can easily lead to problems such as valve core jamming and airtight leakage in subsequent assembly.

[0004] Meanwhile, the separate process requires additional independent cleaning equipment and workstations, resulting in high equipment investment, space occupation, and labor costs. Furthermore, the cleaning cycle time is difficult to match with the rotary assembly cycle time, severely impacting the efficiency of automated continuous operation on the production line. Therefore, there is an urgent need to develop a tooling adapted to rotary assembly lines that can simultaneously clean the internal threads of the valve body during the feeding process, addressing the pain points of existing technologies such as fragmented processes, poor cleanliness, high production costs, and low yield. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a feeding fixture for a rotary solenoid valve assembly production line.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A feeding fixture for a rotary solenoid valve assembly production line includes a base and a rotary body. The rotary body is located on top of the base, and a drive mechanism for rotating the rotary body is located on the outer side of the base. Four mounting plates are located on the top of the rotary body, and horizontal plates are slidably mounted on the top of each of the four mounting plates. Vertical plates are mounted on both sides of each of the four horizontal plates. A transfer mechanism for clamping and transferring valve bodies to be assembled is located on the top of each of the four vertical plates. A cleaning mechanism for cleaning the internal threads of the valve bodies to be assembled is located at both ends of the top of each of the four horizontal plates. A circular groove of the same size is opened in the center of the interior of both the rotary body and the base. A collection mechanism is located inside the circular groove for collecting valve bodies that do not meet the quality requirements before assembly.

[0007] Optionally, the drive mechanism includes a fixed plate mounted on the outer wall of the base, a first motor mounted on the top of the fixed plate, a gear mounted on the output end of the first motor, a circular gear ring mounted on the bottom end of the turntable body, the gear and the gear ring meshing with each other, a rotating groove opened on the top of the base, and a rotating part adapted to the rotating groove mounted on the bottom end of the turntable body.

[0008] Optionally, all four mounting plates are threaded to the top of the turntable body by multiple bolts. Two first sliding grooves are opened on the top of each of the four horizontal plates. A first slider is installed inside each of the two first sliding grooves. The four horizontal plates are respectively installed on the top of the corresponding two first sliders. Two support blocks for placing the valve body are installed on the top of each of the four horizontal plates and between the two vertical plates.

[0009] Optionally, the cleaning mechanism includes two sets of second slide grooves opened at the top of the horizontal plate, each set of second slide grooves having a second slider installed inside, each set of second sliders having a vertical rod installed at the top of the top of the two sets of second sliders, each set of two vertical rods having a third slide groove opened on the outer wall of the side where they are close to each other, each set of two third slide grooves having a third slider installed inside, and a moving block being installed between the two third sliders.

[0010] Optionally, a frame is installed on the outer wall of the movable block on the side away from the vertical plate, a second motor is installed on the inner wall of one side of the frame, a first electric telescopic rod is installed at the output end of the second motor, the telescopic end of the first electric telescopic rod passes through the movable block and is connected to a first rubber block, a sleeve plate is installed on the outer wall of the first rubber block on the side away from the movable block, and an airbag is installed on the outer wall of the sleeve plate.

[0011] Optionally, a second electric telescopic rod is installed inside the first rubber block. One end of the second electric telescopic rod is located inside the sleeve plate, and a nylon brush for rotating and cleaning the internal threads of the valve body is installed at the telescopic end of the second electric telescopic rod.

[0012] Optionally, the transfer mechanism includes a first rotating plate rotatably mounted on the top of the vertical plate, a fourth sliding groove formed on one outer wall of the first rotating plate, a fourth sliding block installed inside the fourth sliding groove, an mounting block installed at the end of the fourth sliding block away from the fourth sliding groove, and a second rotating plate rotatably mounted at the end of the mounting block away from the fourth sliding block.

[0013] Optionally, a mounting bracket is installed on one outer wall of the second rotating plate, and a second rubber block is installed on the outer wall of the mounting bracket away from the second rotating plate. A nozzle is installed at the center of the second rubber block. The interior of the mounting bracket is hollow, and a connection port for connecting to an externally preset gas transmission device is installed on one outer wall of the mounting bracket. The connection port is connected to the nozzle.

[0014] Optionally, the mounting bracket is equipped with fixed seats on both outer walls, and electric push rods are installed on the outer walls of the two fixed seats that are close to each other. Clamping plates are installed on the telescopic ends of the two electric push rods.

[0015] Optionally, the collection mechanism includes a circular block installed at the bottom of the circular groove, a placement seat rotatably mounted on the top of the circular block, a collection box placed inside the placement seat, and the inside of the collection box divided into three collection chambers by three partitions, each of the three partitions having an opening at its top for easy manual or robotic handling.

[0016] The beneficial effects of this invention are: 1. In this invention, the process interval of the rotary table rotation operation is fully utilized. During the idle period of valve body assembly at the previous station, the internal thread cleaning operation of the valve body at the next station is completed simultaneously. The thread cleaning process is integrated into the feeding and transfer process. There is no need to add independent offline cleaning equipment and dedicated station. This completely solves the problem of the separation of cleaning and assembly processes and the mismatch of cycle time in traditional processes. It effectively simplifies the production process, reduces the production line footprint, significantly reduces equipment investment and labor maintenance costs, and significantly improves the overall automation level and continuous production efficiency of the rotary table assembly line.

[0017] 2. This invention employs a retractable rotating nylon brush cleaning structure. The nylon brush is driven into the threaded hole by a second electric telescopic rod, which can adapt to the deep cleaning of the threaded hole and solve the cleaning blind spot problem of traditional air blowing and batch ultrasonic cleaning. At the same time, when the nylon brush rotates at high speed, it relies on centrifugal force to radially open and fit against the inner wall of the thread, which can thoroughly remove residual metal chips, oil stains and attached dust in the thread grooves. The comprehensiveness and precision of cleaning are greatly improved, effectively avoiding the problem of secondary pollution during the valve body transportation process, and ensuring the high cleanliness and consistency of the internal threads of the valve body before assembly.

[0018] 3. Based on the technological advantages of online precision cleaning, this invention can effectively eliminate quality defects such as valve core jamming, improper assembly, and airtight leakage caused by residual impurities in the threads. It significantly reduces the assembly failure rate and rework rate of solenoid valves, ensuring assembly accuracy, sealing performance, and long-term operational stability. Simultaneously, the overall structure is compatible with existing rotary assembly production lines, featuring a compact design that requires no major modifications to existing production lines. Its strong adaptability and practicality effectively fill the technological gap in existing rotary valve body feeding fixtures that lack an integrated online thread cleaning structure.

[0019] 4. In this invention, a nozzle is centrally located at the bottom of the second rubber block. This nozzle can spray high-pressure gas generated by an externally pre-set gas delivery device outwards. While the two nylon brushes of the cleaning mechanism rotate and clean the two internal threaded parts inside the valve body, the first rotating plate can be simultaneously controlled to rotate into a vertical position, and the fourth slider can be controlled to move downwards, driving the mounting bracket and the second rubber block to move downwards together. After ensuring that the second rubber block is tightly abutted against the top of the valve body, the nozzle is controlled to spray high-pressure gas downwards into the interior of the valve body, which can blow away the impurities cleaned by the two nylon brushes, allowing the impurities to be discharged outwards from the threaded holes at both ends of the valve body. This improves the quality of cleaning impurities inside the valve body and avoids the problem of not being able to discharge the cleaned impurities when using a single brushing motion of the nylon brush.

A first linear motor is pre-installed inside each of the two first sliding grooves 16. The two first linear motors can drive the two first sliders 20 to move back and forth within the corresponding first sliding grooves 16, thereby causing the top horizontal plates 13 and the two vertical plates 15 to move and adjust on the top of the mounting plate 12. This facilitates adjustment of the position of the placed valve body and adapts to the precise assembly of the solenoid valve by the assembly mechanism.

[0027] As a technical optimization of the present invention, the cleaning mechanism includes two sets of second slide grooves 17 opened at the top of the horizontal plate 13.

Similarly, a third linear motor is pre-installed inside each of the two third slide grooves 22. The two third linear motors can drive the two third sliders 23 to move up and down inside the corresponding third slide grooves 22, thereby causing the moving block 24 to move up and down between the two vertical rods 18.

[0028] As a technical optimization of the present invention, a frame 25 is installed on the outer wall of the movable block 24 away from the vertical plate 15, and a second motor 26 is installed on the inner wall of the frame 25. A first electric telescopic rod 27 is installed at the output end of the second motor 26. The telescopic end of the first electric telescopic rod 27 passes through the movable block 24 and is connected to a first rubber block 28. A sleeve plate 29 is installed on the outer wall of the first rubber block 28 away from the movable block 24, and an airbag 30 is installed on the outer wall of the sleeve plate 29. After the second motor 26 is started, it can drive the first electric telescopic rod 27, the first rubber block 28, and the sleeve plate 29 to rotate together. During the telescopic process of the first electric telescopic rod 27, it can drive the first rubber block 28 and the sleeve plate 29 to move and adjust the telescopic movement. An air pump is preset in the empty position at the top of the mounting plate 12. The output end of the air pump is connected to the air inlet of the airbag 30 through a hose to facilitate the inflation of the airbag 30.

[0029] As a technical optimization of the present invention, a second electric telescopic rod 32 is installed inside the first rubber block 28. One end of the second electric telescopic rod 32 is located inside the sleeve plate 29, and a nylon brush 31 for rotating and cleaning the internal threads of the valve body is installed at the telescopic end of the second electric telescopic rod 32. During the telescopic process of the second electric telescopic rod 32, it can drive the nylon brush 31 to move and adjust inside the sleeve plate 29, which facilitates the control of the extension and retraction of the nylon brush 31.

[0030] As an optimized technical solution of the present invention, the transfer mechanism includes a first rotating plate 19 rotatably mounted on the top of the vertical plate 15. A fourth sliding groove 33 is formed on one outer wall of the first rotating plate 19. A fourth slider 40 is installed inside the fourth sliding groove 33. A mounting block 34 is installed at the end of the fourth slider 40 away from the fourth sliding groove 33. A second rotating plate 35 is rotatably mounted at the end of the mounting block 34 away from the fourth slider 40. A third motor is preset at the top of the vertical plate 15. The output end of the third motor is connected to the rotating part at one end of the first rotating plate 19, thereby driving the first rotating plate 19 to rotate and adjust at the top of the vertical plate 15. A fourth linear motor is preset inside the fourth sliding groove 33. The fourth linear motor can drive the fourth slider 40 to move inside the fourth sliding groove 33, thereby driving the mounting block 34 and the second rotating plate 35 to move and adjust on one side of the first rotating plate 19. A fourth motor is preset inside the mounting block 34. The output end of the fourth motor is connected to the rotating part of the second rotating plate 35, thereby driving the second rotating plate 35 to rotate and adjust.

[0031] As a technical optimization of the present invention, a mounting bracket 36 is installed on one outer wall of the second rotating plate 35, and a second rubber block 37 is installed on the outer wall of the mounting bracket 36 away from the second rotating plate 35. A nozzle 41 is installed at the center of the second rubber block 37. The interior of the mounting bracket 36 is hollow, and a connection port 42 for connecting to an externally preset gas delivery device is installed on one outer wall of the mounting bracket 36. The connection port 42 is connected to the nozzle 41. The externally preset gas delivery device is connected to the connection port 42 through a pipe, so that the high-pressure gas discharged by the device is delivered to the interior of the connection port 42 and sprayed downward through the nozzle 41. As a technical optimization of the present invention, fixing seats 38 are installed on both outer walls of the mounting bracket 36, and electric push rods 43 are installed on the outer walls of the two fixing seats 38 that are close to each other. Clamping plates 39 are installed on the telescopic ends of the two electric push rods 43. During the telescopic process of the two electric push rods 43, the corresponding clamping plates 39 can be moved and adjusted to facilitate clamping and fixing of the top of the valve body to be assembled.

[0032] As an optimized technical solution of the present invention, the collection mechanism includes a circular block 7 installed at the bottom of a circular groove. A placement seat 8 is rotatably mounted on the top of the circular block 7. A collection box 9 is placed inside the placement seat 8. The inside of the collection box 9 is divided into three collection chambers by three partitions 10. The top of each of the three partitions 10 has an opening 11 for easy manual or robotic handling. A fifth motor is pre-installed inside the circular block 7. The output end of the fifth motor is connected to the rotating part of the placement seat 8, thereby driving the placement seat 8 and the collection box 9 inside it to rotate and adjust, facilitating the rotation of the corresponding collection chamber to a designated position to collect defective valve bodies.

[0033] In this invention, when the user uses the device, the top of the turntable body 2 is in the following state: Figure 1 As shown, the mounting plate 12 located on the front of the turntable body 2 is the first placement station for the valve body to be assembled, and the two cleaning mechanisms above this placement station are as follows: Figure 5The state shown provides sufficient space for the placement of the valve body, and simultaneously controls the position of the horizontal plate 13 on top of the four mounting plates 12 to ensure that the valve body placed on top of the four mounting plates 12 can be accurately assembled after they are rotated to be directly below the assembly equipment. Then, the loading robot arm, which is preset near the front of the turntable body 2, places the valve body to be assembled on top of the two placement blocks on top of the horizontal plate 13 above the mounting plate 12. The two sets of second sliders 21 on top of the horizontal plate 13 are controlled to move towards each other in the corresponding second slide grooves 17, driving the two sets of vertical rods 18 and other components to move and adjust accordingly. At the same time, the telescopic ends of the two first electric telescopic rods 27 are extended together, pushing the two first... Rubber blocks 28 and sleeve plates 29 move synchronously towards each other until the sleeve plates 29 on the side of the two moving blocks 24 are inserted into the threaded holes at both ends of the valve body. The outer side of the side of the two first rubber blocks 28 that is close to each other is tightly abutted against the two ends of the valve body, so as to achieve the effect of tightly clamping and fixing the two ends of the valve body to be assembled placed on the top of the horizontal plate 13. This ensures the stability of the valve body during the rotation and feeding process while the turntable body 2 drives the first placement station to rotate. After the valve body is rotated to the back side at the first placement station, the solenoid valve actuator is accurately installed on the top of the valve body through the assembly equipment preset on the back side of the turntable body 2, so as to achieve the effect of rotating and feeding the valve body. When the first placement station rotates to the back position, the other corresponding mounting plates 12 placement stations on the top of the turntable body 2 rotate to the front, so that the loading robot can sequentially grab the valve bodies to be assembled and place them on the top of the corresponding horizontal plates 13, ensuring that the turntable body 2 can automatically load valve bodies in a production line manner, thereby improving the efficiency of valve body assembly.

[0034] During the assembly process of the valve body placed on top of the aforementioned horizontal plate 13 rotating from the front to the back of the turntable body 2, the valve body to be assembled will have a period of idle time before assembly. In order to ensure that there are no problems with the quality of the solenoid valves assembled later, while the valve body at the previous placement station is being assembled, the two first electric telescopic rods 27 at the next placement station on the left side of the turntable body 2 can be rotated to retract their telescopic ends together, causing the two sleeve plates 29 to move out of the threaded holes at both ends of the valve body. Then, the telescopic ends of the second electric telescopic rods 32 inside the two sleeve plates 29 are controlled to extend together, causing the two nylon brushes 31 to move out of the corresponding sleeves. The plate 29 extends outward into the threaded hole, controlling the two second motors 26 to start together, driving the two first electric telescopic rods 27 and the nylon brushes 31 to rotate together. During the rotation, the ends of the two nylon brushes 31 that are away from the second electric telescopic rods 32 are affected by the centrifugal force of rotation and bend in all directions. At this time, the two nylon brushes 31 can automatically brush and clean the inner walls of the two threaded holes during the rotation, cleaning the impurities attached to the threads of the two threaded holes, ensuring that the threaded parts of the valve body to be assembled are relatively clean, and reducing the adverse effects of impurities on the overall assembly quality and subsequent use of the solenoid valve.

[0035] Since the two nylon brushes 31 can move synchronously with the extension of the extension ends of the two second electric telescopic rods 32, the two nylon brushes 31 can rotate and clean deeper parts of the valve body, improving the comprehensiveness of the cleaning of the valve body by the two nylon brushes 31.

[0036] In addition, a transfer mechanism is provided at the top of one of the vertical plates 15 in the placement station. After the first rotating plate 19 rotates to a vertical position at the top of the two vertical plates 15, the second rotating plate 35 is positioned horizontally at the top of the two vertical plates 15. Figure 10 and Figure 11 As shown, the fourth slider 40 can be controlled to move downward inside the fourth slide groove 33, driving the second rotating plate 35 and its bottom mounting bracket 36 and the second rubber block 37 to move downward together until the second rubber block 37 is tightly abutted against the top of the valve body, so that it has a pressing and limiting effect on the top of the valve body placed on the top of the horizontal plate 13, further improving the stability of the valve body placed on the top of the horizontal plate 13.

[0037] Meanwhile, since a nozzle 41 is located at the center of the bottom of the second rubber block 37, the nozzle 41 can spray out high-pressure gas generated by the externally preset gas transmission equipment. While the two nylon brushes 31 of the cleaning mechanism rotate and clean the two internal threaded parts inside the valve body, the first rotating plate 19 can be controlled to rotate to a vertical position, and the fourth slider 40 can be controlled to move downward, driving the mounting bracket 36 and the second rubber block 37 to move downward together. After ensuring that the second rubber block 37 is in close contact with the top of the valve body, the nozzle 41 is controlled to spray high-pressure gas downward into the interior of the valve body, which can blow away the impurities cleaned by the two nylon brushes 31, so that the impurities can be discharged outward from the threaded holes at both ends of the valve body. This improves the quality of cleaning impurities inside the valve body and avoids the problem that the cleaned impurities cannot be discharged outward when cleaning with a single brushing motion of the nylon brushes 31.

[0038] Furthermore, by using nozzle 41 to spray high-pressure gas into the interior of the valve body, the moisture or rust inhibitor generated inside the valve body during storage can be blown away and dried simultaneously, preventing these impurities from remaining inside the valve body and affecting the subsequent valve body assembly quality.

[0039] After cleaning the impurities inside the valve body, the telescopic ends of the two second electric telescopic rods 32 are controlled to retract and reset together, causing the two nylon brushes 31 to be stored inside the corresponding sleeves 29. Then, the telescopic ends of the two first electric telescopic rods 27 are controlled to extend together, causing the two first rubber blocks 28 to re-close tightly against both ends of the valve body. The two airbags 30 set outside the sleeves 29 are controlled to inflate and collide, filling the gap between the two sleeves 29 and the inner wall of the threaded hole. Then, the nozzle 41 located on the top of the valve body can be controlled to continue to deliver gas to the inside of the valve body, which has the effect of preliminary detection of the airtightness inside the valve body and improves the applicability of the two cleaning mechanisms and the transfer mechanism.

[0040] After testing the airtightness of the valve body, the nozzle 41 stops spraying air, and the fourth slider 40 moves upward inside the fourth slide groove 33. Then, the first rotating plate 19 rotates and resets to its original horizontal state at the top of the vertical plate 15, maintaining the state in which the two first rubber blocks 28 are tightly abutting against both ends of the valve body. Next, the two third sliders 23 can be controlled to move upward inside the corresponding third slide groove 22, driving the moving block 24 and the two sleeve plates 29 to move upward together for adjustment. This causes the valve body, which is tightly abutted and clamped by the two first rubber blocks 28, to move upward between the two vertical plates 15 until the valve body moves upward to a position higher than the two vertical plates 15. Then, the appearance quality of the valve body is automatically detected by a vision inspection device (such as an industrial camera) preset on the left side of the turntable body 2. At this time, one of the second motors 26 can be controlled to rotate slowly, which can drive the valve body to rotate and adjust together. This facilitates the vision inspection device to perform a comprehensive inspection of the appearance quality of the valve body, improving the comprehensiveness of the appearance quality inspection of the valve body.

[0041] After the two cleaning mechanisms, in conjunction with the transfer mechanism, sequentially clean, test the airtightness, and inspect the appearance of the valve body, if there are no related problems with the valve body, the two first rubber blocks 28 and the second rubber block 37 can be kept in a state of abutment and limitation against the two ends and top of the valve body, waiting for the turntable body 2 to drive it to rotate directly below the assembly equipment. If the valve body has problems such as impurities in the internal thread area that cannot be completely cleaned, defects in airtightness, and defects in appearance quality, the first rotating plate 19 can be controlled to rotate at the top of the vertical plate 15 to a vertical state, and the fourth slider 40 can be controlled to move downward inside the fourth slide groove 33, driving... After the second rubber block 37 abuts against the top of the valve body, the telescopic ends of the two electric push rods 43 are extended together, causing the two clamping plates 39 to abut tightly against the top sides of the valve body, thus clamping and fixing the top sides of the valve body with the two clamping plates 39. Then, the two first electric telescopic rods 27 are retracted to their original positions, releasing the state of the two first rubber blocks 28 abutting tightly against the two ends of the valve body. As the fourth slider 40 slides upward and resets inside the fourth slide groove 33, it causes the valve body to slowly move upward from the top of the horizontal plate 13 until the valve body moves to the designated height. Then, the first rotating plate 19 is rotated and reset at the top of the vertical plate 15. Figure 5 After reaching the state shown, control the second rotating plate 35 to rotate 180 degrees, causing the valve body held by the two clamping plates 39 to rotate to a position close to the circular groove. At this time, one of the collection chambers of the collection box 9 is located close to the left side of the turntable body 2. After controlling the two electric push rods 43 to drive the clamping plate 39 to retract and return to its original position, the valve body with impurities in the internal threaded part that cannot be completely cleaned and removed can fall downward into the collection chamber for collection. Similarly, if the valve body has an airtightness problem, the placement seat 8 can be rotated 120 degrees on top of the circular block 7, causing the collection box 9 to rotate, so that the second collection chamber rotates to a position close to the left side of the turntable body 2. At this time, the transfer mechanism repeats the above operation, and the valve body with airtightness problem can be placed inside the second collection chamber. If the valve body has appearance quality problems, the placement seat 8 can be rotated 120 degrees on top of the circular block 7, so that the third collection chamber rotates to a position close to the left side of the turntable body 2. The rotation mechanism continues to repeat the above operation, and the valve body with appearance quality problems can be placed inside the third collection chamber. This achieves the effect of classifying and collecting valve bodies with different quality problems, which is convenient for subsequent staff to quickly identify and trace the reasons for the valve body's non-conformity, and helps to improve the corresponding processing quality in the subsequent production process of the valve body.
