Description

Technical Field

[0001] This invention belongs to the field of O-ring assembly technology, specifically relating to an automatic O-ring assembly device. Background Technology

[0002] O-rings are rubber sealing rings with a circular cross-section. They are called O-rings because of their O-shaped cross-section. O-rings are suitable for use on various mechanical equipment, providing a sealing function under specified temperatures, pressures, and different liquid and gas media, whether stationary or in motion. They are used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastics machinery, agricultural machinery, and various instruments and meters.

[0003] Currently, for some very thin O-rings, the installation of these products is mostly done manually, with virtually no automation and a very high degree of reliance on manual labor. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic O-ring assembly device that reduces labor costs and improves production efficiency.

[0005] The technical solution of the present invention is as follows:

[0006] An automatic O-ring assembly device includes a worktable, an automatic bearing feeding device, an O-ring measuring fiber optic device, a material turning device, and two O-ring vibratory feeder aligning devices. The automatic bearing feeding device, the O-ring measuring fiber optic device, the material turning device, and the O-ring vibratory feeder aligning devices are all mounted on the worktable. A material shifting device is mounted on the worktable. The automatic bearing feeding device, the material turning device, and the O-ring measuring fiber optic device are mounted on one side of the material shifting device and arranged sequentially from left to right.

[0007] Both sides of the material turning device are equipped with O-ring assembly equipment located on the workbench. The O-ring vibrating plate alignment device is located on one side of the O-ring assembly equipment. The O-ring assembly equipment takes out O-rings from the O-ring vibrating plate alignment device and installs them on the bearings of the material shifting device.

[0008] The bearings on the material shifting device move intermittently, so that the bearings are displaced below the material turning device, the O-ring measuring fiber optic device, and the O-ring assembly equipment.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] 1. This invention achieves the interval displacement of bearings through a material shifting device, so that the bearings can be moved to the bottom of the O-ring measuring fiber optic device, the material flipping device, the two O-ring vibrating plate alignment device, and the two O-ring assembly equipment, and the O-rings and bearings are assembled through the O-ring assembly equipment, thereby reducing labor costs and improving production efficiency.

[0011] 2. This invention uses an O-ring measuring fiber optic device to detect materials after assembly, thus avoiding situations where the O-ring is not assembled onto the bearing;

[0012] In summary, this invention has the advantages of reducing labor costs and improving production efficiency.

[0013] Furthermore, the O-ring assembly equipment includes a multi-position cylinder on the worktable, a first rotary cylinder on the multi-position cylinder, a mold on the first rotary cylinder, a limiting block on one side of the mold, a square cylinder fixed on the limiting block, and a material clamping structure between the limiting block and the O-ring vibrating plate aligning device. The material clamping structure takes out the O-ring from the O-ring vibrating plate aligning device and rotates it to below the limiting block so that the O-ring is hung on the limiting block. One end of the mold is rotated to the limiting block so that the O-ring is fitted onto the mold.

[0014] The limiting block and the material clamping structure are both fixed on the worktable;

[0015] The square cylinder can push the material clamping structure to move, so that the O-ring hanging on the limiting block is misaligned vertically;

[0016] The mold is located above the material transfer device and can be lowered and inserted into the bearing so that the O-ring is assembled on the bearing.

[0017] Furthermore, the limiting block has a groove on the side facing the mold, and the mold can rotate into the groove. The side of the limiting block with the groove is provided with a downwardly inclined protrusion. When the material clamping structure rotates to below the limiting block, the O-ring is hooked onto the protrusion.

[0018] Furthermore, the material clamping structure includes a second rotary cylinder located on the worktable, a guide rail cylinder disposed on the second rotary cylinder, and a gripper cylinder disposed on the guide rail cylinder. The gripper cylinder removes the O-ring from the O-ring vibrating plate alignment device, and the square cylinder can push the gripper cylinder to move.

[0019] Furthermore, the guide rail cylinder is equipped with a pressure reducing valve.

[0020] Furthermore, the gripper cylinder is equipped with two picking needles for spreading the material. The picking needles contact the lower side of the limiting block and are provided with a curved part for the protruding rod to pass through. When the picking needles rotate to the lower side of the limiting block, the material is located at the end of the protruding rod away from the limiting block.

[0021] Furthermore, the material transfer device includes a feeding plate on the workbench, multiple reset structures slidably connected to the feeding plate, a clamping plate disposed on the reset structure, a first slide rail plate located on one side of the feeding plate, a transverse moving plate slidably connected to the first slide rail plate, a longitudinal moving cylinder located on the transverse moving plate, and a transverse moving cylinder connected to the transverse moving plate. The bearing feeds the material onto the feeding plate, and a horizontal plate is disposed on the upper side of the feeding plate. The first slide rail plate is fixed on the workbench.

[0022] The longitudinal moving cylinder can push the clamping plate against the horizontal plate so that the clamping plate clamps the bearing.

[0023] Furthermore, the side of the feeding plate is provided with a second slide rail plate fixed to the workbench, and the second slide rail plate is provided with a second slide rail for the resetting structure to slide laterally.

[0024] Furthermore, the reset structure includes a sliding block, a groove formed on the lower side of the sliding block, a movable groove formed on the upper side of the sliding block, and a movable block slidably connected in the movable groove. The sliding block is slidably connected to the second slide rail through the groove, and the movable block is connected to the clamping plate.

[0025] Furthermore, the longitudinal moving cylinder is provided with a longitudinal moving plate that abuts against the clamping plate. Attached Figure Description

[0036] 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.

[0037] like Figure 1-9As shown, an automatic O-ring assembly device includes a worktable 19, an automatic bearing feeding device 21, an O-ring measuring fiber optic device 16, a material turning device 20, and two O-ring vibrating plate aligning devices 10. The O-ring vibrating plate aligning devices 10 are equipped with a material feeding trough 11. The automatic bearing feeding device 21, the O-ring measuring fiber optic device 16, the material turning device 20, and the O-ring vibrating plate aligning devices 10 are all fixed on the worktable 19. A material shifting device is provided on the worktable 19. The automatic bearing feeding device 21, the material turning device 20, and the O-ring measuring fiber optic device 16 are arranged on one side of the material shifting device, sequentially from left to right. O-ring assembly devices are located on the worktable 19 on both the left and right sides of the material turning device 20. The O-ring vibrating plate aligning devices 10 are located on one side of the O-ring assembly devices. The O-ring assembly devices take O-rings from the O-ring vibrating plate aligning devices 10 and install them on the bearings on the material shifting devices.

[0038] When in use, the automatic bearing feeding device 21 places the bearing on the material shifting device. The material shifting device moves the bearing to the bottom of the first O-ring assembly device. The O-ring assembly device takes the O-ring from the feeding slot 11 of the O-ring vibrating plate aligning device 10 and assembles it on the bearing. At this time, the material shifting device moves the bearing to the bottom of the material flipping device 20. After the material flipping device 20 flips the bearing, the material shifting device moves the bearing to the bottom of another O-ring assembly device and assembles another O-ring on the bearing. At this time, the O-ring assembly on the bearing is completed. The material shifting device moves the bearing to the bottom of the O-ring measuring fiber optic device 16. The O-ring measuring fiber optic device 16 detects the assembly of the O-ring and the bearing. The assembly of the bearing and the O-ring is then completed.

[0039] In this embodiment, the O-ring assembly equipment includes a multi-position cylinder 6 bolted to the worktable 19, a first rotary cylinder 7 bolted to the multi-position cylinder 6, a mold 8 bolted to the first rotary cylinder 7, a limiting block 5 located on one side of the mold 8, a square cylinder 4 bolted to the limiting block 5, and a material clamping structure disposed between the limiting block 5 and the O-ring vibrating plate alignment device 10. The material clamping structure takes out O-rings from the material picking slot 11 of the O-ring vibrating plate alignment device 10. The O-ring is rotated to below the limiting block 5 so that it is hung on the limiting block 5. One end of the mold 8 is rotated to the limiting block 5 so that the O-ring is fitted onto the mold 8. The limiting block 5 is fixed to the worktable 19 by bolts. The material clamping structure is fixed to the worktable 19. The square cylinder 4 can push the material clamping structure to move so that the O-ring hanging on the limiting block 5 is vertically misaligned. The mold 8 is located above the material shifting device and can be lowered to insert into the bearing so that the O-ring is assembled on the bearing. In use... The material gripping structure takes out the O-ring from the feeding slot 11 of the O-ring vibrating plate alignment device 10 and rotates it to below the limiting block 5. At this time, the square cylinder 4 pushes the material gripping structure to move backward. As the material gripping structure moves, the O-ring is hooked on the limiting block 5 and gradually shifts up and down. Then, the first rotating cylinder 7 drives the mold 8 to rotate 90° counterclockwise. One end of the mold 8 rotates to the limiting block 5. During the rotation, the upper end of the O-ring is fitted onto the mold 8, thereby realizing the automatic feeding of the O-ring. Then the first rotating cylinder 7 rotates the mold 8 to the limiting block 5. Cylinder 7 drives mold 8 to rotate and reset. At this time, mold 8 is aligned with the bearing on the material transfer device. Multi-position cylinder 6 drives mold 8 to move down through first rotary cylinder 7 so that the O-ring on mold 8 is assembled on the bearing. At this time, the O-ring and bearing are assembled. When first rotary cylinder 7 drives mold 8 to rotate and reset, material clamping structure rotates and resets, and takes out O-ring from material chute 11. Then, the O-ring is assembled on the bearing according to the above process, thereby realizing the automatic assembly between O-ring and bearing.

[0040] In this embodiment, the limiting block 5 has a groove 51 on the side facing the mold, and the mold 8 can rotate into the groove 51. The side of the limiting block 5 with the groove 51 is welded with a downwardly inclined protruding rod 52. When the material clamping structure rotates to the bottom of the limiting block 5, the O-ring is hooked on the protruding rod 52. In use, the material clamping structure rotates the O-ring to the bottom of the limiting block 5. At this time, the square cylinder 4 drives the material clamping structure to move backward, and the O-ring is hooked on the protruding rod 52 and gradually shifts up and down. When the mold 8 rotates counterclockwise, since the protruding rod 52 is set on the side of the limiting block 5 with the groove 51, when the mold 8 rotates into the groove 51, the O-ring on the protruding rod 52 is hooked on the mold 8. After the mold 8 has rotated, the O-ring is completely fitted on the mold 8, which makes it easy to fit the O-ring on the mold 8.

[0041] In this embodiment, the material clamping structure includes a second rotary cylinder 9 fixed to the workbench 19 by bolts, a guide rail cylinder 3 fixed to the output shaft of the second rotary cylinder 9 by bolts, and a gripper cylinder 2 fixed to the guide rail cylinder 3. The gripper cylinder 2 takes out the O-ring from the material picking slot 11 of the O-ring vibrating plate alignment device 10. The square cylinder 4 can push the gripper cylinder 2 to move. In use, the guide rail cylinder 3 drives the gripper cylinder 2 to move into the material picking slot 11. The gripper of the gripper cylinder 2 inserts into the O-ring and opens the O-ring. Then the guide rail cylinder 3 drives the gripper cylinder 2 to reset. At this time, the second rotary cylinder 9 drives the gripper cylinder 2 and the O-ring to rotate to below the limit block 5 through the guide rail cylinder 3, thereby realizing the feeding of the O-ring. After the O-ring is put on the mold 8, the second rotary cylinder 9 drives the gripper cylinder 2 to reset and pick up the material again.

[0042] In this embodiment, the guide rail cylinder 3 is equipped with a pressure reducing valve; during use, the pressure reducing valve allows the square cylinder 4 to push the guide rail cylinder 3 backward, ensuring its operation.

[0043] In this embodiment, two material-picking needles 1 for spreading the material are threadedly fixed on the gripper of the gripper cylinder 2. The material-picking needle 1 contacts the lower side of the limiting block 5 and is provided with a curved part 101 for the protruding rod 52 to pass through. When the material-picking needle 1 rotates to below the limiting block 5, the material is located at the end of the protruding rod 52 away from the limiting block 5. In use, the material-picking needle 1 on the gripper cylinder 2 takes out the O-ring. At this time, the O-ring is located on the side of the curved part 101 away from the gripper cylinder 2. The gripper cylinder 2 drives the material-picking needle 1 to rotate to below the limiting block 5. During the rotation, the material-picking needle 1 passes through the protruding rod 52 through the curved part 101 to avoid contact with the protruding rod 52 when the material-picking needle 1 rotates. When the square cylinder 4 drives the material-picking needle 1 to move through the guide rail cylinder 3 and the gripper cylinder 2, the O-ring is hooked on the protruding rod 52 when the material-picking needle 1 moves. At this time, the material-picking needle 1 continues to move, causing the O-ring to be misaligned vertically.

[0044] In this embodiment, the material transfer device includes a feeding plate 22 fixed to the workbench 19 by bolts, a plurality of reset structures slidably connected to the feeding plate 22, a clamping plate 15 disposed on the reset structure, a first slide rail plate 18 located on one side of the feeding plate 22, a transverse moving plate 14 slidably connected to the first slide rail plate 18, a longitudinal moving cylinder 13 fixed to the transverse moving plate 14 by bolts, and a transverse moving cylinder 12 connected to the transverse moving plate 14. The bearing is fed onto the feeding plate 22. A horizontal plate 24 is fixed to the upper side of the feeding plate 22 by bolts. The first slide rail plate 18 is fixed to the workbench 19. The output shaft of the longitudinal moving cylinder 13 is connected to the clamping plate 15, and the longitudinal moving cylinder 13 can push the clamping plate 15 against the horizontal plate 24 so that the clamping plate 15 clamps the bearing.

[0045] During use, the bearing is fed onto the feeding plate 22, and the longitudinal moving cylinder 13 pushes the clamping plate 15 to abut against the horizontal plate 24. At this time, the bearing is clamped by the clamping plate 15. The transverse moving cylinder 12 drives the clamping plate 15 to move laterally through the transverse moving plate 14 and the longitudinal moving cylinder 13. After the movement is completed, the longitudinal moving cylinder 13 drives the clamping plate 15 to reset. Then, the transverse moving cylinder 12 drives the clamping plate 15 through the transverse moving plate 14 and the longitudinal moving cylinder 13. When the clamping plate 15 is reset, the clamping plate 15 does not contact the bearing, thus preventing the bearing from shifting.

[0046] In this embodiment, a second slide rail plate 23 fixed on the worktable 19 is provided on the side of the feeding plate 22. The second slide rail plate 23 is provided with a second slide rail for the resetting structure to slide laterally. In use, the resetting structure can slide laterally through the second slide rail to ensure its use.

[0047] In this embodiment, the reset structure includes a sliding block 152, a groove 153 formed on the lower side of the sliding block 152, a movable groove 155 formed on the upper side of the sliding block 152, and a movable block 154 slidably connected in the movable groove 155. The sliding block 152 is slidably connected to the second slide rail through the groove 153, and the movable block 154 is bolted to the clamping plate 15. When it is necessary to move the bearing, the clamping plate 15 slides longitudinally along the movable groove 155 through the movable block 154, and the sliding block 152 moves along the second slide rail through the groove 153, thereby realizing the longitudinal and lateral adjustment of the clamping plate 15.

[0048] In this embodiment, the output shaft of the longitudinal moving cylinder 13 is connected to the longitudinal moving plate 17, and the longitudinal moving plate 17 is connected to the clamping plate 15. In use, the longitudinal moving cylinder 13 drives the clamping plate 15 to move through the longitudinal moving plate 17, ensuring the connection between the longitudinal moving cylinder 13 and the clamping plate 15.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
