Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of environmental protection devices, and particularly relates to a floating type O-ring feeding device. BACKGROUND

[0002] As a common sealing element, O-rings are widely used in the fields of machinery, hydraulics, pneumatics, etc. due to their simple structure and stable sealing performance. In the prior art, O-rings are usually made of rubber or elastic materials and have good elasticity and resilience, so that they can form a sealing effect under pressure in a groove. In actual production and assembly process, in order to realize mass supply of O-rings, a special feeding device is often needed. The existing feeding device usually adopts a vibrating disc, a conveying belt or a rotary disc type mechanism to arrange, orient and convey the scattered and stacked O-rings, so as to provide stable feeding support for subsequent automatic assembly. The mechanical structure of these devices usually includes a guide rail, a feeding channel and a positioning mechanism to ensure that the O-rings do not jam during the conveying process and can be accurately sent to the assembly station. Some devices also cooperate with a detection and sorting unit to screen O-rings of different specifications or abnormal shapes, so as to improve the reliability and consistency of the feeding and meet the needs of modern production lines for automatic installation of sealing elements.

[0003] The inventor found in actual assembly production that the assembly process in the prior art still heavily relies on manual operation or clamping feeding of a mechanical arm for O-ring feeding work, and therefore has the following problems:

[0004] 1. Manual feeding seriously consumes labor, and a traditional mechanical arm cannot meet the continuous feeding work of multiple batches of O-rings. For example, when multiple positions inside a certain assembly part cover body need to place O-rings, the feeding efficiency of the mechanical arm is extremely slow and cannot effectively meet the rapid pre-assembly work on the continuous production line.

[0005] 2. In the existing O-ring feeding equipment, O-rings are in a scattered state inside the hopper, and it is currently difficult to realize self-stacking and arranging operation of the O-rings, so that manual operation or mechanical arm picking of the O-rings will seriously affect the feeding efficiency and make the picking operation slow.

[0006] Therefore, how to provide a floating type O-ring feeding device is a problem to be solved by those skilled in the art. SUMMARY

[0007] An object of the present application is to provide a floating type O-ring feeding device which can effectively improve the feeding and feeding efficiency of O-rings on the assembly line, effectively replace manual operation, and be more efficient than the existing mechanical arm.

[0008] According to an embodiment of the present invention, a floating O-ring feeding device includes a hopper, a feeding component is provided inside the hopper for pushing the O-ring, a feeding end is fixed at the bottom of the hopper, and a stacking mechanism is provided at the top of the hopper near the axis of the feeding end, the stacking mechanism is used to assist the O-rings in stacking and feeding.

[0009] A hexagonal support frame assembly is installed below the feed end. Six sets of transmission mechanisms are installed below the support frame assembly. A connecting plate assembly is installed between the transmission mechanism and the support frame assembly. The connecting plate assembly includes a first triangular rod and a second triangular rod distributed at a 60-degree angle to each other. An external support assembly is installed on the side of the transmission mechanism. The first triangular rod and the second triangular rod control three sets of transmission mechanisms respectively. The transmission mechanism controls the external support assembly to center and clamp the O-ring.

[0010] Furthermore, the transmission mechanism includes a moving frame and two sets of reversing teeth. The two sets of reversing teeth are rotatably arranged inside the moving frame. The left and right sides of the reversing teeth are respectively engaged with a biting rod. The two sets of biting rods are in opposite directions, and the ends of the biting rods are movably connected to a pushing rod through a side ear. One end of the pushing rod is movably connected to an external support assembly.

[0011] Furthermore, a drive rod is fixedly connected to the top of the single set of bite rods, the top of the drive rod is aligned with the first triangular rod or the second triangular rod, and the bottom of the single set of bite rods is elastically connected to the moving frame through a pressure spring.

[0012] Furthermore, the support frame assembly includes a shelf and six sets of slides, each corresponding to a set of six movable frames. The movable frames are slidably mounted on the slides. Six sets of drive motors and actuators are mounted on the top of the shelf. The bottom of the drive motors is fixed with lead screws, and the top of the sides of the movable frames are threadedly connected to the lead screws via drive seats.

[0013] Furthermore, the output end below the actuator is fixed to the first or second triangular rod through the storage rack, and the actuator drives the driving rod to move up and down inside the moving frame through the first or second triangular rod.

[0014] Furthermore, the external support assembly includes a straight rod and a clamping groove. The clamping groove is opened on the side of the straight rod, and the top of the clamping groove is set as a deflector. The feeding end includes a feeding ring and six sets of bottom-clamping protrusions. The six sets of bottom-clamping protrusions are fixed in a ring array at the bottom of the feeding ring, and the bottom-clamping protrusions and the deflector are distributed alternately.

[0015] Furthermore, the side of the straight rod away from the clamping groove is connected to the biting rod drive through two sets of pushing rods, and the side of the straight rod is limited to slide with the outside of the moving frame through the limiting slide rod.

[0016] Furthermore, the stacking mechanism includes a top plate and two sets of electric push rods. The two sets of electric push rods are fixed on the outer side of the hopper, and the output end of the electric push rods is fixed to the bottom surface of the top plate. The electric push rods drive the top plate to move up and down above the hopper.

[0017] Furthermore, a servo motor is fixed on one side of the top surface of the top plate, and the output shaft of the servo motor is connected to a bidirectional screw through a reversing bevel gear group. The bidirectional screw is rotatably set at the bottom of the top plate through a limit seat.

[0018] Furthermore, the surface of the bidirectional screw is threaded with two sets of threaded drive pairs, and the threaded drive directions of the two sets of threaded drive pairs are opposite. The middle of the bidirectional screw, located on the opposite side of the two sets of threaded drive pairs, is connected to two sets of unidirectional screws through a three-link bevel gear set. The surface of the unidirectional screw is also provided with threaded drive pairs, and the bottom of the four sets of threaded drive pairs is fixedly connected to an oblique push rod.

[0019] The beneficial effects of this invention are:

[0020] This invention, through its transmission mechanism and external support assembly, allows the first and second triangular rods to remain in their positions while the transmission motor drives the moving frame to descend. Under the elastic action of the pressure spring, the meshing rod is displaced upwards. Simultaneously, under the meshing of the reversing teeth, another set of meshing rods moves downwards. Thus, with the connection of the pushing rod and the stabilization of the limiting slide, the straight rod is forced to move towards the moving frame, causing the clamping groove to loosen the O-ring and achieve the material release effect. Conversely, when the actuator synchronously drives the first or second triangular rod to descend, the straight rod can then move the O-ring downwards through the clamping groove, bringing it to the designated material release position. Compared to the placement operation in existing technologies, this invention only requires an externally configured moving mechanism to efficiently and quickly achieve the placement operation on the workpiece surface.

[0021] This invention uses two sets of first and second triangular rods, which correspond to the control of three sets of drive motors and actuators, respectively. This means that only the first and second triangular rods need to be controlled separately, in conjunction with the control of the drive motors on the external support components. This allows the three sets of external support components to clamp the O-rings, while the other set performs an upward reset operation. This reciprocating motion enables continuous and efficient feeding of O-rings. Compared with manual operation and the use of robotic arms in the prior art, this invention can effectively improve feeding efficiency and is suitable for use in high-speed assembly line environments.

[0022] This invention utilizes a stacking mechanism. After the servo motor is started, the meshing effect of the three-unit bevel gear group in the middle of the bidirectional screw allows four sets of threaded transmission pairs on the surfaces of both the bidirectional and unidirectional screws to move or separate. Simultaneously, a slanted push rod is fixed at the bottom of the threaded transmission pair. In the alignment case, the slanted push rod can be inserted into the middle of the O-ring. During the spreading process, the O-rings can be aligned and centered, thus achieving the stacking operation. In conjunction with the feeding component, the O-rings are pushed to accumulate at the top of the feed end. At the same time, the electric push rod is controlled to drive the top plate to rise as a whole, preventing the slanted push rod from obstructing the accumulation of O-rings above the feed end.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0036] refer to Figures 1-9 The system includes a hopper 1, inside which a feeding assembly 3 is installed to push the O-rings. The bottom of the hopper 1 is fixed with a feeding end 4. The top of the hopper 1 is equipped with a stacking mechanism 2 near the axis of the feeding end 4. The stacking mechanism 2 is used to assist in stacking and feeding the O-rings. Below the feeding end 4, a hexagonal support frame assembly 5 is installed. Below the support frame assembly 5, six sets of transmission mechanisms 6 are installed. Above the transmission mechanisms 6 and between the support frame assembly 5, a connecting plate assembly 7 is installed. The connecting plate assembly 7 includes a first triangular rod 71 and a second triangular rod 72 that are distributed at a 60-degree angle to each other. An external support assembly 8 is installed on the side of the transmission mechanism 6. The first triangular rod 71 and the second triangular rod 72 control the three sets of transmission mechanisms 6 respectively. The transmission mechanism 6 controls the external support assembly 8 to center and clamp the O-rings.

[0037] In this implementation scheme, batches of O-rings can be directly fed into the inner side of hopper 1 from the top port of hopper 1. Under the action of the feeding component 3, the O-rings are quantitatively gathered at the top position of the feeding end 4, which facilitates subsequent stacking operations. In practice, the feeding component 3 can be driven by a motor to reciprocate the feeding operation of the O-rings. Its main function is to make the O-rings gather in the top area of ​​the feeding end 4. The stacking mechanism 2 can perform centering and stacking operations on the O-rings above the feeding end 4 after starting, so that the O-rings can move downward neatly inside the feeding end 4. The downward movement effect here comes from the gravity of the O-rings themselves. The feeding end 4 only provides the outer limit. In this way, the O-rings can be stacked in the feeding end 4, and are picked up by the outer support component 8 below in a single and continuous manner.

[0038] The main function of the support frame assembly 5 below the feed end 4 is to provide support and stability for subsequent components. For example, the connecting plate assembly 7 and the transmission mechanism 6 are both located below the support frame assembly 5. The first triangular rod 71 and the second triangular rod 72 correspond to three sets of transmission mechanisms 6, so that the six sets of transmission mechanisms 6 present two different motion effects. The transmission mechanism 6 only serves as a control unit and assembly unit. The control of the transmission mechanism 6 by the connecting plate assembly 7 is ultimately fed back to the outer support assembly 8, so that the outer support assembly 8 can perform a clamping operation on the O-ring. It can be seen that when the three sets of transmission mechanisms 6 control the outer support assembly 8 to clamp or pick up the O-ring, the other three sets of transmission mechanisms 6 control the outer support assembly 8 to maintain a stable clamping of the O-ring. In this way, the six sets of transmission mechanisms 6 cooperate with each other to achieve continuous feeding operation.

[0039] refer to Figure 1 , Figures 4-9 The transmission mechanism 6 includes a movable frame 61 and two sets of reversing gears 62. The two sets of reversing gears 62 are rotatably disposed inside the movable frame 61. Meshing rods 63 are engaged on the left and right sides of the reversing gears 62 respectively. The two sets of meshing rods 63 are in opposite directions, and the ends of the meshing rods 63 are movably connected to a pushing rod 66 via side ears. One end of the pushing rod 66 is movably connected to the outer support assembly 8. A driving rod 64 is fixedly connected to the top of each set of meshing rods 63. The top of the driving rod 64 is aligned with either the first triangular rod 71 or the second triangular rod 72. The bottom of each set of meshing rods 63 is elastically connected to the movable frame 61 via a pressure spring 65. The support frame assembly 5 includes a shelf 51 and six sets of slides 52. The six sets of slides 52 correspond to the six sets of movable frames 61 respectively. The movable frames 61 are slidably disposed on the slides 52. Six sets of drive motors 53 and actuator cylinders 54 are disposed on the top of the shelf 51. A lead screw 55 is fixed to the bottom of the drive motor 53. The top of the side of the movable frame 61 is threadedly connected to the lead screw 55 via a drive seat. The output end of the actuator 54 passes through the shelf 51 and is fixed to the first triangular rod 71 or the second triangular rod 72. The actuator 54 drives the driving rod 64 to move up and down inside the moving frame 61 through the first triangular rod 71 or the second triangular rod 72.

[0040] In this embodiment, the two sets of reversing teeth 62 rotatably arranged inside the moving frame 61 mainly play a control role. When the first triangular rod 71 or the second triangular rod 72 presses down on a single set of meshing rods 63, the meshing rods 63 will drive the other set of meshing rods 63 to move in the opposite direction through the meshing effect of the reversing teeth 62. At this time, if it is in the pressing state, the ends of the two sets of meshing rods 63 will move away from each other, and the ends of the meshing rods 63 are connected to the pushing rods 66 through the side ears. One end of the pushing rods 66 is movably connected to the straight rods 81. In this way, both ends of the straight rods 81 will be pulled by the pushing rods 66 respectively. Under the stabilization of the limiting slide rods 67, the straight rods 81 as a whole will move laterally to one side of the moving frame 61, thereby realizing the operation of loosening the O-ring.

[0041] Conversely, when the first triangular rod 71 or the second triangular rod 72 rises, the pressure spring 65 that is elastically connected between the bottom of the single set of biting rods 63 and the moving frame 61 will release its elastic force, and the ends of the two sets of biting rods 63 will move closer to each other. In this way, the straight rod 81 can move away from the moving frame 61, thereby making external clamping contact with the O-ring.

[0042] After the drive motor 53 starts, it can drive the moving frame 61 to move up and down on the side of the slide table 52 through the rotation of the lead screw 55, thereby cooperating to realize the overall raising or lowering operation of the transmission mechanism 6. It is worth noting that at this time, in order to prevent the external support component 8 from moving, the actuator 54 needs to synchronously control the first triangular rod 71 or the second triangular rod 72 to move up and down, so as to ensure that the position of the external support component 8 remains unchanged.

[0043] refer to Figure 4 , Figure 6 , Figure 8 and Figure 9 The external support assembly 8 includes a straight rod 81 and a clamping groove 82. The clamping groove 82 is formed on the side of the straight rod 81, and the top of the clamping groove 82 is set as a deflector 83. The feed end 4 includes a feed ring 41 and six sets of bottom-clamping protrusions 42. The six sets of bottom-clamping protrusions 42 are fixed in a circular array at the bottom of the feed ring 41, and the bottom-clamping protrusions 42 and the deflector 83 are staggered. The side of the straight rod 81 away from the clamping groove 82 is connected to the meshing rod 63 through two sets of pushing rods 66. The side of the straight rod 81 is limited and slidable to the outside of the moving frame 61 through a limiting slide rod 67.

[0044] In this embodiment, when the straight rod 81 approaches the O-ring, the clamping groove 82 on the side of the straight rod 81 will contact the O-ring, thereby stabilizing the position of the O-ring. In this way, after the other three sets of external support components 8 release the O-ring, the O-ring can remain stable and will not fall off. This can be understood as the three sets of straight rods 81 clamping and limiting the O-ring at an angle of 120 degrees to each other.

[0045] Meanwhile, the other three sets of straight rods 81 are controlled by the transmission mechanism 6 to retract inward. At this time, under the control of the actuator 54 and the transmission motor 53, the transmission mechanism 6 drives the outer support assembly 8 to rise until the taper 83 above the straight rod 81 aligns with the O-ring stuck at the bottom protrusion 42. Then, the three sets of straight rods 81 are controlled to center, so that the taper 83 can push the O-ring to disengage from the bottom protrusion 42, thereby completing the pickup. After the pickup is completed, the six sets of transmission mechanisms 6 move down at the same time, and the above operation is repeated to complete the continuous feeding of O-rings.

[0046] refer to Figures 1-3The stacking mechanism 2 includes a top plate 21 and two sets of electric push rods 28. The two sets of electric push rods 28 are fixed to the outer side of the hopper 1, and the output end of the electric push rods 28 is fixed to the bottom surface of the top plate 21. The electric push rods 28 drive the top plate 21 to move up and down above the hopper 1. A servo motor 22 is fixed to one side of the top surface of the top plate 21. The output shaft of the servo motor 22 is connected to a bidirectional screw 24 through a reversing bevel gear set 23. The bidirectional screw 24 is rotatably set at the bottom of the top plate 21 through a limit seat. Two sets of threaded transmission pairs 26 are threadedly connected to the surface of the bidirectional screw 24. The threaded transmission directions of the two sets of threaded transmission pairs 26 are opposite. The middle part of the bidirectional screw 24, located on the opposite side of the two sets of threaded transmission pairs 26, is connected to two sets of unidirectional screws 27 through a triple bevel gear set 25. The surface of the unidirectional screws 27 is also provided with threaded transmission pairs 26. The bottom of the four sets of threaded transmission pairs 26 is fixedly connected to an inclined push rod 29.

[0047] In this embodiment, under the actuation of the feeding component 3, the O-rings will first gather alternately in the top area of ​​the feeding end 4. At this time, the electric push rod 28 controls the top plate 21 to fall and fit against the top of the hopper 1. During this process, the four sets of inclined push rods 29 will insert into the hollow area above the feeding end 4 with the axis of the feeding end 4 as the direction of movement, so that the O-rings are on the outside of the four sets of inclined push rods 29. Then, the servo motor 22 drives the bidirectional screw 24 to rotate at the bottom of the top plate 21 through the control of the reversing bevel gear group 23. The reversing bevel gear group 23 is composed of two sets of bevel gears meshing with each other at a 90-degree angle. The two sets of threaded drive pairs 26 on the surface of the screw 24 move in opposite directions. The two sets of inclined push rods 29 at the bottom of these two sets of threaded drive pairs 26 will push the O-ring laterally. Meanwhile, the middle of the bidirectional screw 24 drives the two sets of unidirectional screws 27 to rotate through the triple bevel gear set 25. The triple bevel gear set 25 consists of three sets of bevel gears meshing at ninety degrees. In this way, the threaded drive pairs 26 on the surface of the two sets of unidirectional screws 27 will move in opposite directions, realizing the longitudinal pushing of the O-ring by the two sets of inclined push rods 29. With the lateral and longitudinal pushing, the O-ring is stacked at the top of the feed end 4.

[0048] Working principle: First, O-rings are placed into the hopper 1. Under the action of the feeding assembly 3, the O-rings gather at the top area of ​​the feed end 4. Then, the electric push rod 28 controls the top plate 21 to move downward at the top of the hopper 1, simultaneously driving four sets of inclined push rods 29 to insert into the top port area of ​​the feed end 4 for initial pickup of the O-rings. Subsequently, the servo motor 22 drives the bidirectional screw 24 to rotate through the reversing bevel gear set 23. Two sets of threaded transmission pairs 26 move in opposite directions on the surface of the bidirectional screw 24, driving the two sets of inclined push rods 29 to laterally push the outer O-rings. At the same time, the bidirectional screw 24 drives two sets of unidirectional screws 27 to rotate through the triple bevel gear set 25. The threaded transmission pairs on the surface of the two sets of unidirectional screws 27 rotate. The auxiliary rod 26 moves in opposite directions to push the O-ring longitudinally, gradually aligning the center of the O-ring with the axis of the feed ring 41. Then, the oblique push rod 29 releases the O-ring, which falls along the inside of the feed ring 41 under gravity and is caught at the bottom protrusion 42, thus achieving the stacking operation of the O-rings inside the feed ring 41. Subsequently, the three sets of drive motors 53 on the surface of the shelf 51 are controlled. These three sets of drive motors 53 correspond to the three sets of transmission mechanisms 6 below the first triangular rod 71. The drive motors 53 directly drive the lead screw 55 to rotate, and the moving frame 61 is limited and slidable by the slide table 52, while also being threadedly connected to the lead screw 55, allowing the three sets of moving frames 61 to move. As the rods gradually move upward, the three sets of actuators 54 simultaneously drive the first triangular rod 71 to rise, causing the three sets of moving frames 61 to move the three sets of external support components 8 towards the position of the bottom protrusion 42. At this time, the actuators 54 control the first triangular rod 71 to move upward. Under the elastic action of the pressure spring 65 inside the moving frame 61, the meshing rod 63 loses the resistance of the driving rod 64 and will return to its original position. At this time, under the meshing action of the reversing gear 62, the other set of meshing rods 63 will slide in the opposite direction of movement. The ends of the two sets of meshing rods 63 gradually approach each other, and the end positions are movably connected to the straight rod 81 through the pushing rod 66, so that the straight rod 81 is limited by the limiting slide rod 67. Under the pushing of the push rod 66, the O-ring is displaced towards the O-ring. At this time, the taper 83 above the straight rod 81 contacts the single O-ring that is engaged with the bottom protrusion 42, completing the pickup operation. Then, the drive motor 53 drives the three sets of transmission mechanisms 6 to move down. At this time, the actuator 54 synchronously drives the first triangular rod 71 to move down, so that the taper 83 moves the O-ring away from the bottom protrusion 42. The other three sets of transmission mechanisms 6 rise synchronously with the second triangular rod 72. The O-ring at the bottom protrusion 42 is picked up by repeating the previous steps. Finally, the O-ring is stuck in the clamping groove 82 at the bottommost side of the three sets of straight rods 81. At this time, after releasing the three sets of straight rods 81, the O-ring falls normally to the assembly position.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
