Description

Technical Field

[0001] The present invention relates to the technical field of the assembly of static seal rings, and particularly to a fully automated assembly device for mechanical seal static rings. Background Art

[0002] The mechanical seal static ring is an important component in a mechanical seal and is usually in a ring structure. It consists of a ceramic ring and a rubber ring, and the assembly of the static ring is completed by embedding the ceramic ring into the rubber ring. The fully automated assembly device for the static ring consists of a ceramic ring feeding mechanism, a rubber ring feeding mechanism, and an assembly mold. The ceramic ring and the rubber ring are respectively fed into the assembly mold by the ceramic ring feeding mechanism and the rubber ring feeding mechanism, and the ceramic ring and the rubber ring are pressed together by a rubber hammer driven by a cylinder to complete the assembly of the static ring.

[0003] However, in the existing ceramic ring feeding mechanism, a double-layer discharging belt design is adopted. The ceramic rings in the storage hopper are transported to the discharging belt through the storage hopper conveyor belt. During the transportation process of the conveyor belt, a large number of ceramic rings in the storage hopper are likely to fall out, easily resulting in the accumulation of ceramic rings on the discharging belt and causing some ceramic rings to fall out of the discharging belt. Summary of the Invention

[0004] In order to reduce the possibility of ceramic ring accumulation during feeding, the present application provides a fully automated assembly device for mechanical seal static rings.

[0005] The fully automated assembly device for mechanical seal static rings provided by the present application adopts the following technical solutions:

[0006] A fully automated assembly device for mechanical seal static rings includes a frame and a ceramic ring feeding device for feeding ceramic rings. The ceramic ring feeding device includes a discharging mechanism, a conveying mechanism for sorting ceramic rings, and a feeding mechanism. The discharging mechanism includes a storage hopper, a temporary storage plate, and a driving component. The storage hopper is arranged on the frame. The temporary storage plate is slidably connected in the storage hopper in the vertical direction. A plurality of storage grids are provided on the temporary storage plate. Two blocking plates are respectively rotatably connected to the plurality of storage grids. The two blocking plates together form a supporting groove. An outlet is provided on the side surface of the storage hopper. A conveyor belt is drivingly connected to the frame and penetrates into the storage hopper. The driving component is used to drive the sliding of the temporary storage plate and the transmission of the conveyor belt. When discharging ceramic rings, the temporary storage plate moves to make the blocking plates rotate, and the ceramic rings in the supporting groove fall onto the conveyor belt.

[0007] By adopting this technical solution, the hopper is used to store large quantities of ceramic rings. The temporary storage plate, its storage grid, and the material blocking plate above it form an orderly temporary storage and discharge structure. A drive assembly drives the temporary storage plate and the conveyor belt, allowing the ceramic rings to be discharged from the hopper through the temporary storage plate and conveyor belt in an orderly manner according to a set rhythm. During discharge, only one layer of ceramic rings is dropped onto the discharge belt at a time, reducing the possibility of large numbers of ceramic rings accumulating and being squeezed at the bottom of the hopper.

[0008] Preferably, the two material blocking plates are respectively provided with partitions, and the two partitions are respectively rotatably connected to side plates, and the ends of the side plates away from the partitions are slidably connected to the material storage grid. When the two material blocking plates are rotated until the ceramic ring is out of the way, the two partitions move to be parallel to each other.

[0009] By adopting the above technical solution, the ceramic ring can be better limited and guided during the discharging process, preventing the ceramic ring from tilting, flipping or getting stuck when leaving the supporting groove, ensuring that the ceramic ring can fall smoothly and accurately onto the conveyor belt, thereby improving the reliability and stability of the ceramic ring transmission, thereby ensuring the smooth progress of the subsequent assembly process, and reducing equipment failures and defective rates caused by ceramic ring transmission problems.

[0010] Preferably, a mounting seat is provided on the frame, a limit brush is rotatably connected to the mounting seat, and a connecting ring is rotatably connected to the mounting seat, a rubber rod is provided on the connecting ring, and the driving assembly simultaneously drives the rotation of the connecting ring, and the driving assembly can drive the rubber rod to rotate toward one side of the storage hopper until it is close to the conveyor belt.

[0011] By employing this technical solution, the limiting brushes on the mounting bracket on the frame initially limit and organize the ceramic rings on the conveyor belt, preventing them from shifting or rolling during transport. Driven by the drive assembly, the rubber rod on the connecting ring rotates toward the storage hopper, closer to the conveyor belt, further limiting and guiding the ceramic rings, ensuring they remain neatly arranged on the conveyor belt and facilitating the subsequent automated assembly process.

[0012] Preferably, the driving assembly includes a first motor, several transmission shafts, multiple protrusions and a first torsion spring, several of the transmission shafts are respectively connected to the frame, the conveyor belt is simultaneously wound around several transmission shafts, multiple protrusions are respectively arranged at both ends of the conveyor belt in the width direction, and multiple protrusions are evenly distributed around the transmission path of the conveyor belt. A driving rod is provided on the connecting ring, and the first torsion spring is arranged on the connecting ring. The first torsion spring drives the reset of the connecting ring. When the protrusion moves into the storage hopper, the protrusion lifts the temporary storage plate. When the protrusion moves to the connecting ring, the protrusion pushes the driving rod to rotate the connecting rod.

[0013] By adopting the above-mentioned technical solution, multiple protrusions can simultaneously drive the sliding of the temporary storage plate and the rotation of the connecting ring. When the protrusion moves into the storage hopper, the protrusion lifts the temporary storage plate. The sliding of the temporary storage plate causes the material blocking plate on the storage grid to rotate, causing the ceramic ring in the supporting groove to fall onto the conveyor belt; when the protrusion moves to the connecting ring, the protrusion pushes the driving rod to rotate the connecting ring. The rotation of the connecting ring drives the rubber rod on it to rotate toward the side of the storage hopper until it approaches the conveyor belt, thereby limiting and organizing the ceramic rings on the conveyor belt. This ensures the close coordination of each link in the ceramic ring loading process and improves the loading efficiency.

[0014] Preferably, the frame is provided with a correction channel which can cooperate with the protrusion, and when the protrusion moves into the correction channel, the side wall of the correction channel abuts against the protrusion.

[0015] By adopting this technical solution, the sidewalls of the correction channel abut against the bump, accurately limiting and correcting the bump's trajectory. This prevents the bump from deforming due to various factors during movement, ensuring that the bump always moves accurately along the predetermined path. This increases the likelihood that all actions related to the bump will be performed accurately, improving the stability and reliability of the entire ceramic ring loading process.

[0016] Preferably, the temporary storage plate is rotatably connected to a stirring paddle, and the driving assembly is also used to drive the rotation of the stirring paddle, the stirring paddle includes a rotating rod, a plurality of rubber rods and a telescopic rod, the rotating rod is rotatably connected to the temporary storage plate, a second torsion spring is sleeved on the rotating rod, the second torsion spring drives the reset of the rotating rod, the plurality of rubber rods are evenly distributed around the circumference of the rotating rod, one end of the telescopic rod is coaxially and slidably connected to any rubber rod, the temporary storage plate is slidably connected to a connecting rod, one end of the connecting rod is rotatably connected to the telescopic rod, the other end of the connecting rod passes through the temporary storage plate and is fixedly connected to a force-bearing block, and when the protrusion moves into the storage hopper, it abuts against the force-bearing block and drives the force-bearing block to move.

[0017] By adopting the above technical solution, the stirring paddle stirs the ceramic rings in the storage hopper, which can effectively prevent the ceramic rings from piling up and getting stuck in the storage hopper, making the ceramic rings more evenly distributed in the storage hopper, making it easier for the storage grid on the temporary storage plate to accurately receive the ceramic rings, and improving the storage and discharge efficiency of the storage hopper.

[0018] Preferably, the conveying mechanism includes a guide plate and a loosening block, the guide plate is fixedly connected to the frame, a guide channel is provided on the guide plate, the loosening block is slidably connected to the guide plate, and the loosening block is arranged in a tapered shape from one end close to the storage hopper to the end away from the storage hopper.

[0019] By adopting the above technical solution, the guiding channel provides an accurate path for the transmission of the ceramic ring, ensuring that the ceramic ring is transmitted along a straight line direction and avoiding the deviation of the ceramic ring during the transmission process. The loose block is tapered and can slide on the guiding plate, which can loosen the ceramic ring during the transmission process, prevent the ceramic rings from squeezing and stacking with each other, ensure that the ceramic rings move orderly on the conveyor belt at a proper spacing, provide good conditions for subsequent grasping and assembling operations, and improve the assembling efficiency and product quality.

[0020] Preferably, two beat rods are respectively slidably connected to the guiding plate, and the two beat rods can move into the guiding channel, and the sliding directions of the two beat rods are opposite.

[0021] By adopting the above technical solution, the beat rods can control the transmission rhythm of the ceramic ring. By adjusting the positions of the beat rods in the guiding channel, the accurate adjustment of the transmission speed and spacing of the ceramic ring can be realized, and the production coordination and production efficiency of the whole assembling equipment can be improved.

[0022] Preferably, two sets of discharging mechanisms and conveying mechanisms are respectively provided. The feeding mechanism includes two mechanical claws and a vibration channel. The vibration channel is arranged on the frame, and the two mechanical claws are respectively movably connected to the frame. The two mechanical claws respectively grab the ceramic rings on the two conveying mechanisms and move them to the vibration channel.

[0023] By adopting the above technical solution, setting two sets of discharging mechanisms and conveying mechanisms, together with two mechanical claws and a vibration channel, can realize the parallel feeding and transmission of the ceramic rings, greatly improving the feeding efficiency compared with a single set of structure and meeting the production requirements of higher production volumes. At the same time, through the grasping and moving of the ceramic rings by the mechanical claws, the ceramic rings can be accurately placed on the vibration channel, preparing for the subsequent assembling process.

[0024] Preferably, it further includes a visual recognition system. The visual recognition system is used to identify the front and back sides of the ceramic ring. The visual recognition system includes at least two industrial cameras, an image processor and a controller. The two industrial cameras are respectively arranged above the two conveying mechanisms for collecting the image information of the ceramic rings; the image processor is communicatively connected to the industrial cameras and is used to receive and analyze the image information collected by the industrial cameras to identify the front and back sides of the ceramic rings; the controller is communicatively connected to the image processor and the two mechanical claws respectively; when the image processor identifies the front and back information of the ceramic ring, it transmits this information to the controller, and the controller controls the two mechanical claws to perform grasping and flipping operations on the ceramic ring according to the received information, so that all the ceramic rings grabbed and placed on the vibration channel are in the state of facing upwards.

[0025] By adopting the above technical solution, the industrial camera collects the image information of the ceramic ring, the image processor analyzes and processes it, and the controller controls the mechanical claw to grab and flip the ceramic ring according to the analysis result, ensuring that all the ceramic rings placed on the vibration channel are in the state of facing upwards, guaranteeing the consistent installation direction of the ceramic rings during the assembly process, reducing the defective rate caused by the incorrect installation direction of the ceramic rings, and improving the product quality and production efficiency.

[0026] The technical effects of the present invention are mainly reflected in the following aspects:

[0027] 1. By setting the temporary storage plate and the storage compartments in the present invention, the storage hopper is used to store a large number of ceramic rings, and the temporary storage plate, the storage compartments thereon, and the blocking plate form an orderly temporary storage and discharging structure. The driving component drives the temporary storage plate to slide and the conveyor belt to drive, enabling the ceramic rings to be discharged orderly from the storage hopper through the temporary storage plate and the conveyor belt according to the set rhythm. When discharging, only one layer of ceramic rings falls onto the discharge belt each time. This reduces the possibility of a large number of ceramic rings accumulating and squeezing at the bottom of the storage hopper;

[0028] 2. By setting the partition plate and the side plate in the present invention, it plays a better role in limiting and guiding the ceramic rings during the discharging process, preventing the ceramic rings from tilting, flipping or jamming when disengaging from the supporting groove, ensuring that the ceramic rings can fall smoothly and accurately onto the conveyor belt, improving the reliability and stability of the ceramic ring transmission, and thus guaranteeing the smooth progress of the subsequent assembly process and reducing the equipment failures and defective rate caused by the ceramic ring transmission problems;

[0029] 3. By setting the limiting brush and the rubber rod in the present invention, the limiting brush on the mounting seat on the frame can conduct preliminary limiting and sorting of the ceramic rings on the conveyor belt, preventing the ceramic rings from shifting or rolling during the transmission process. The rubber rod on the connecting ring rotates towards the side of the storage hopper and approaches the conveyor belt under the drive of the driving component, which can further limit and guide the ceramic rings, making the ceramic rings keep neatly arranged on the conveyor belt, facilitating the smooth progress of the subsequent automated assembly process.

Detailed implementation manners

[0041] The following is a further detailed description of the present application in combination with the attached Figures 1 - 10 to make the technical solution of the present application easier to understand and master.

[0042] The embodiment of the present application discloses a fully automatic assembly device for a mechanical seal static ring.

[0043] Referring to Figure 1 and Figure 2 , a fully automatic assembly device for a mechanical seal static ring in this embodiment includes a frame 1 and a ceramic ring feeding device 2 for feeding ceramic rings. The ceramic ring feeding device

[0044] Referring to Figure 7 and Figure 8The discharging mechanism 3 includes a storage hopper 7, a temporary storage plate 8, a plurality of sliding rods 9 and a driving assembly 10. The storage hopper 7 is fixedly connected to the frame 1. The temporary storage plate 8 is slidably connected to the storage hopper 7 in the vertical direction. A plurality of storage grids 11 are provided on the temporary storage plate 8. The plurality of storage grids 11 are arranged in a rectangular row. Two blocking plates 12 are connected to the plurality of storage grids 11 respectively along the horizontal direction. The two blocking plates 12 are "V" shaped to form a supporting groove 13. A plurality of sliding rods 9 are provided. They are respectively fixedly connected to multiple material blocking plates 12 in the same column, multiple chutes are opened in the storage hopper 7, multiple sliding rods 9 correspond to the multiple chutes, and the multiple sliding rods 9 slide along the length direction of the corresponding chutes. The ends of the two material blocking plates 12 away from the sliding rods 9 are respectively fixedly connected with partitions 15, and the sides of the two partitions 15 away from the material blocking plates 12 are respectively rotatably connected with side plates 16, and the ends of the side plates 16 away from the partitions 15 are slidably connected to the storage grid 11.

[0045] Reference Figure 5 and Figure 6 A discharge port 17 is provided on the side of the storage hopper 7, and a transmission belt 18 is connected to the frame 1. The transmission belt 18 passes into the storage hopper 7. The driving assembly 10 is used to drive the sliding of the temporary storage plate 8 and the transmission of the transmission belt 18. When the ceramic ring is discharged, the temporary storage plate 8 moves to rotate the material blocking plate 12, and the ceramic ring in the supporting groove 13 falls onto the transmission belt 18.

[0046] Reference Figure 7 and Figure 8 The storage hopper 7 is used to store a large number of ceramic rings, and the temporary storage plate 8 and the storage grid 11 and the blocking plate 12 thereon constitute an orderly temporary storage and discharge structure. The driving component 10 drives the temporary storage plate 8 to slide and the conveyor belt 18 to transmit, so that the ceramic rings can be discharged in an orderly manner from the storage hopper 7 through the temporary storage plate 8 and the conveyor belt 18 according to the set rhythm. During discharge, only one layer of ceramic rings falls onto the discharge belt at a time. The possibility of a large number of ceramic rings piling up and being squeezed at the bottom of the storage hopper 7 is reduced. The partition 15 and the side plate 16 play a better role in limiting and guiding the ceramic rings during the discharge process, preventing the ceramic rings from tilting, flipping or getting stuck when they leave the supporting groove 13, ensuring that the ceramic rings can fall smoothly and accurately onto the conveyor belt 18, improving the reliability and stability of the ceramic ring transmission, and thus ensuring the smooth progress of the subsequent assembly process, and reducing equipment failures and defective rates caused by ceramic ring transmission problems.

[0047] Reference Figure 2 and Figure 9The frame 1 is fixedly connected to a mounting base 19, to which a limit brush 20 is rotatably connected. A drive motor 21 is fixedly connected on the mounting base, and one end of the output shaft of the drive motor 21 is coaxially and fixedly connected to the limit brush 20. The drive motor 21 is used to drive the rotation of the limit brush 20; and a connecting ring 22 is coaxially and rotatably connected to the mounting base 19 with the limit brush 20. A rubber rod 23 is fixedly connected to the circumferential side of the connecting ring 22. The axial direction of the rubber rod 23 is parallel to the axial direction of the limit brush 20. The driving assembly 10 simultaneously drives the rotation of the connecting ring 22. The driving assembly 10 can drive the rubber rod 23 to rotate toward the side of the storage hopper 7 until it approaches the conveyor belt 18. The limit brush 20 of the mounting base 19 on the frame 1 can perform preliminary limiting and sorting of the ceramic rings on the conveyor belt 18 to prevent the ceramic rings from offsetting or rolling during the transmission process. The rubber rod 23 on the connecting ring 22 rotates toward the side of the storage hopper 7 and close to the conveyor belt 18 under the drive of the driving assembly 10, which can further limit and guide the ceramic rings so that the ceramic rings remain neatly arranged on the conveyor belt 18, which is conducive to the smooth progress of the subsequent automated assembly process.

[0048] Reference Figure 5 and Figure 6 The driving assembly 10 includes a first motor 24, several transmission shafts, multiple protrusions 26 and a first torsion spring 27. The several transmission shafts are respectively connected to the frame 1, and the conveyor belt 18 is simultaneously wound on the several transmission shafts. The multiple protrusions 26 are respectively fixedly connected to the two ends of the conveyor belt 18 in the width direction. The multiple protrusions 26 are evenly distributed around the transmission path of the conveyor belt 18. A driving rod 28 is fixedly connected to the circumferential side surface of the connecting ring 22. The first torsion spring 27 is sleeved on the mounting seat 19. The two ends of the first torsion spring 27 are respectively fixedly connected to the mounting seat 19 and the connecting ring 22. The first torsion spring 27 drives the reset of the connecting ring 22. When the protrusion 26 moves into the storage hopper 7, the protrusion 26 lifts the temporary storage plate 8. When the protrusion 26 moves to the connecting ring 22, the protrusion 26 pushes the driving rod 28 to rotate the connecting rod 35.

[0049] Reference Figure 1 and Figure 2 , multiple protrusions 26 can simultaneously drive the sliding of the temporary storage plate 8 and the rotation of the connecting ring 22. When the protrusion 26 moves into the storage hopper 7, the protrusion 26 lifts the temporary storage plate 8. The sliding of the temporary storage plate 8 causes the material blocking plate 12 on the storage grid 11 to rotate, so that the ceramic ring in the supporting groove 13 falls onto the conveyor belt 18; when the protrusion 26 moves to the connecting ring 22, the protrusion 26 pushes the driving rod 28 to rotate the connecting ring 22. The rotation of the connecting ring 22 drives the rubber rod 23 on it to rotate toward the side of the storage hopper 7 until it approaches the conveyor belt 18, thereby limiting and arranging the ceramic rings on the conveyor belt 18. It ensures the close cooperation of each link in the process of loading ceramic rings and improves the loading efficiency.

[0050] ReferenceFigure 1 and Figure 4 On the frame 1, a correction channel 29 that can cooperate with the convex block 26 is fixedly connected. When the convex block 26 moves into the correction channel 29, the side wall of the correction channel 29 abuts against the convex block 26. The abutment of the side wall of the correction channel 29 against the convex block 26 can precisely limit and correct the movement trajectory of the convex block 26. It prevents the convex block 26 from being deformed due to various factors during the movement process, ensures that the convex block 26 always moves accurately along the predetermined path, and thus improves the possibility that each action related to the convex block 26 can be accurately performed, and improves the stability and reliability of the entire ceramic ring loading process.

[0051] Refer to Figure 5 and Figure 6 As shown in FIGS. and, a stirring paddle 30 is rotatably connected to the temporary storage plate 8. The driving assembly 10 is also used to drive the rotation of the stirring paddle 30. The stirring paddle 30 includes a rotating rod 31, a plurality of rubber rods 32 and a telescopic rod 33. The rotating rod 31 is rotatably connected to the temporary storage plate 8. A second torsion spring 34 is sleeved on the rotating rod 31, and the second torsion spring 34 drives the reset of the rotating rod 31. The plurality of rubber rods 32 are evenly distributed around the circumference of the rotating rod 31. One end of the telescopic rod 33 is coaxially and slidably connected to any one of the rubber rods 32. A connecting rod 35 is slidably connected to the temporary storage plate 8. One end of the connecting rod 35 is rotatably connected to the telescopic rod 33. The other end of the connecting rod 35 penetrates through the temporary storage plate 8 and is fixedly connected to a force-bearing block 36. When the convex block 26 moves into the storage hopper 7, it abuts against the force-bearing block 36 and drives the force-bearing block 36 to move. The stirring paddle 30 stirs the ceramic rings in the storage hopper 7, which can effectively prevent the ceramic rings from accumulating and jamming in the storage hopper 7, make the ceramic rings more evenly distributed in the storage hopper 7, facilitate the storage grid 11 on the temporary storage plate 8 to accurately receive the ceramic rings, and improve the storage and discharging efficiency of the storage hopper 7.

[0052] Refer to Figure 1 and Figure 4 As shown in FIGS. and, the conveying mechanism 4 includes a guide plate 37 and a loosening block 38. The guide plate 37 is fixedly connected to the frame 1. A guide channel 39 is formed on the guide plate 37. The loosening block 38 is slidably connected to the guide plate 37. A second air cylinder 48 is fixedly connected to the guide plate 37. One end of the piston rod of the second air cylinder 48 is fixedly connected to the conveying block. The end of the loosening block 38 close to the storage hopper 7 to the end far from the storage hopper 7 is tapered. The guide channel 39 provides an accurate path for the transmission of the ceramic rings, ensures that the ceramic rings are transmitted along a straight line direction, and avoids the deviation of the ceramic rings during the transmission process. The loosening block 38 is tapered and can slide on the guide plate 37, which can loosen the ceramic rings during the transmission process, prevent the ceramic rings from being squeezed and stacked with each other, ensure that the ceramic rings move on the conveyor belt 18 at a proper interval and in an orderly manner, provide good conditions for the subsequent grasping and assembling operations, and improve the assembling efficiency and product quality.

One end of the piston rod of each first cylinder 46 is fixedly connected to a sliding plate 47. The two tempo rods 40 are fixedly connected to the two sliding plates 47 and can be moved into the guide channel 39. The two tempo rods 40 slide in opposite directions. The tempo rods 40 can control the transmission rhythm of the ceramic rings. By adjusting the position of the tempo rods 40 in the guide channel 39, the transmission speed and spacing of the ceramic rings can be precisely adjusted, thereby improving the production coordination and production efficiency of the entire assembly equipment.

The loading mechanism 5 includes two mechanical claws 41 and a vibration channel 42. The vibration channel 42 is provided on the frame 1. The two mechanical claws 41 are movably connected to the frame 1. The two mechanical claws 41 respectively grab the ceramic rings on the two conveying mechanisms 4 and move them to the vibration channel 42. The two sets of discharging mechanisms 3 and conveying mechanisms 4, combined with the two mechanical claws 41 and the vibration channel 42, can achieve parallel loading and transmission of ceramic rings. Compared with a single-group structure, the loading efficiency is greatly improved and the production demand for higher output is met. At the same time, by grabbing and moving the ceramic rings by the mechanical claws 41, the ceramic rings can be accurately placed on the vibration channel 42, preparing for the subsequent assembly process.
