Description

Technical Field

[0001] This invention relates to the field of automatic feeding equipment technology, specifically to an automatic feeding equipment for oil seal skeletons. Background Technology

[0002] An oil seal skeleton is a ring-shaped metal component embedded inside the elastomer of an oil seal. It is typically made of low-carbon steel sheet through cold stamping and is often bowl-shaped or cup-shaped. The automatic oil seal skeleton feeding equipment is a key piece of equipment in an automated oil seal production line. It is a specialized automated device used to automatically and accurately transport oil seal skeletons to designated workstations. During the feeding process, operators pour batches of stamped oil seal skeletons into a vibratory feeder hopper. The vibratory feeder, through electromagnetic vibration, causes the skeletons to rise along a spiral track and then enter a linear vibratory feeder. The feeder smoothly delivers the material to the picking position. Once the photoelectric / fiber optic sensor at the picking position detects that the skeleton is in place, it sends a "material present" signal to the PLC. After the PLC determines that the host can release the material and that the robot arm will not interfere, it issues a gripping command. The servo slide / cylinder drives the picking mechanism to move to the picking position and uses a pneumatic gripper to clamp the oil seal skeleton. After gripping, the mechanism rises, translates, and moves to the position above the mold cavity. After releasing the material, the picking mechanism returns to its original position to wait for the host to send the next signal. The above process is repeated to achieve continuous automated feeding.

[0003] Oil seal skeletons are typically made of thin steel plates through cold stamping, forming a ring-shaped thin-walled structure. To accommodate the installation, fixing, and sealing requirements of oil seals, most products have flanged or tapered ends. When stacked in batches in the vibratory feeder hopper, the oil seal skeletons collide with the inner wall of the track and adjacent skeletons as they rise along the track. This causes irregular deformations such as tapered end deformation and out-of-roundness of the ring. Furthermore, the internal support claws are mostly three-claw point-contact designs, concentrating the force in a localized area of ​​the inner hole during clamping. For oil seal skeletons that have already undergone irregular deformation, the claws are prone to rigid contact with the root of the tapered end during the opening process. This leads to localized stress overload, which not only further exacerbates the shrinkage and warping of the edges, but also causes the already thin-walled ring to undergo elliptical deformation under non-uniform radial force, affecting the subsequent mold insertion accuracy. As a result, workers need to regularly check the condition of the vibratory feeder's outlet skeleton and manually pick out unqualified skeletons with severe warping of the edges, deformation of the edges, and out-of-roundness of the rings to prevent them from entering the clamping process. This is not only labor-intensive and inefficient, but also highly subjective, making it difficult to guarantee the complete removal of unqualified skeletons. Therefore, we propose an automatic oil seal skeleton feeding device. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic feeding device for oil seal skeletons, so as to solve the problem mentioned in the background art of manually picking out unqualified skeletons with severe edge warping, end deformation, and out-of-roundness of the rings, and preventing them from entering the clamping process. This is not only labor-intensive and inefficient, but also subject to strong subjectivity in manual screening, making it difficult to ensure the complete removal of unqualified skeletons.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic feeding device for oil seal skeletons, including a vibratory feeder hopper and a device housing, with grippers installed on the surface of the device housing and an electromagnetic vibration unit installed on the surface of the device housing; it also includes a linear material trough, with the electromagnetic vibration unit located at the bottom of the linear material trough, the linear material trough located at the outlet of the vibratory feeder hopper, and a connecting hole opened on the surface of the linear material trough.

The material support assembly senses whether the oil seal skeleton has completely fallen above the material support assembly. The flipping mechanism is located below the material receiving assembly.

When it detects that the oil seal skeleton opening is facing down, the flipping mechanism first adjusts the position of the oil seal skeleton, and then flips the oil seal skeleton opening to face up. The thin-wall correction mechanism is located above the material-bearing assembly. When the oil seal skeleton moves above the material-bearing assembly and keeps the opening facing upward, the thin-wall correction mechanism performs graded correction on the thin-wall deformation of the oil seal skeleton.

A rotating component that drives the electromagnet to rotate is provided on the inner wall of the adjusting seat. Multiple arc-shaped plates are provided on the outer side of the adjusting seat.

[0012] The adjusting component includes a transmission rod fixedly connected to the arc-shaped plate. An air storage chamber is opened on the top of the adjusting seat.

[0013] The corrective component includes a correction plate that is slidably connected to the inner wall of the adjusting seat. Multiple correction plates correspond to multiple arc-shaped plates.

[0015] This invention has at least the following beneficial effects: 1. In use, this application uses a flipping mechanism to detect the orientation of the oil seal skeleton opening. When the oil seal skeleton opening is detected to be facing downwards, the flipping mechanism first adjusts the position of the oil seal skeleton, and then flips the oil seal skeleton opening upwards to avoid the oil seal skeleton with the opening facing downwards affecting the gripper's gripping.

[0016] 2. After the oil seal skeleton is completely placed above the material receiving assembly with its opening facing upwards, the position of the oil seal skeleton is pre-adjusted by the thin-wall correction mechanism. When the thin-wall correction mechanism corrects the thin-wall deformation of the oil seal skeleton, it pre-detects the degree of dent caused by the impact and applies a corresponding corrective force to the side wall of the oil seal skeleton according to the deformation amplitude. This corrects the elliptical, dented, and other deformations of the oil seal skeleton to the standard roundness, reducing the labor intensity of operators and avoiding errors caused by manual intervention.

[0019] 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.

[0020] Please see Figures 1 to 12This invention provides a technical solution: an automatic oil seal skeleton feeding device, including a vibratory feeder hopper 1 and a device housing 2. The device housing 2 has grippers 3 and an electromagnetic vibration unit 4 mounted on its surface. It also includes a linear feed trough 5, with the electromagnetic vibration unit 4 located at the bottom of the linear feed trough 5, which is located at the outlet of the vibratory feeder hopper 1. A connecting hole 6 is provided on the surface of the linear feed trough 5. A material-bearing component 7 is located on the inner wall of the connecting hole 6, and senses whether the oil seal skeleton has completely fallen onto the material-bearing component 7. A flipping mechanism 8 is located below the material-bearing component 7. The flipping mechanism 8 detects the orientation of the oil seal skeleton opening. When the opening of the oil seal skeleton is detected to be downward, the flipping mechanism 8 first adjusts the position of the oil seal skeleton, and then flips the opening of the oil seal skeleton upward. A thin-wall correction mechanism 9 is located above the material-bearing component 7. When the oil seal skeleton moves above the material-bearing component 7 and maintains an upward opening, the thin-wall correction mechanism 9 performs graded correction of the thin-wall deformation of the oil seal skeleton.

[0021] When in use, the operator pours the batch of cold-stamped oil seal skeletons into the vibratory feeder hopper 1, starts the equipment, the PLC initializes all components, the gripper 3 resets to the origin, and the electromagnetic vibration unit 4, pneumatic system and detection system enter standby mode; the material shortage alarm sensor monitors the material level in the hopper in real time to ensure sufficient material quantity.

[0022] The electromagnetic vibrator of the vibratory feeder hopper 1 is started, and the vibration frequency is adjusted by the frequency controller, which drives the skeleton to rise along the spiral track. After the oil seal skeleton enters the straight material trough 5, the electromagnetic vibration unit 4 at the bottom of the straight material trough 5 is started. The high-frequency micro-amplitude vibration pushes the skeleton to be transported smoothly along the trough. The width of the straight material trough 5 is preset according to the skeleton specifications to avoid shaking. The oil seal skeleton slides into the material receiving component 7 through the connecting hole 6. The material receiving component 7 detects whether the oil seal aggregate has completely fallen into the material receiving component 7. After the oil seal aggregate has completely fallen into the material receiving component 7, the flipping mechanism 8 detects the opening orientation of the oil seal skeleton. When the opening of the oil seal skeleton is detected to be facing down, the flipping mechanism 8 first adjusts the position of the oil seal skeleton, and then flips the opening of the oil seal skeleton to face up to avoid the oil seal skeleton with the opening facing down affecting the gripper 3.

[0023] After the oil seal skeleton is completely placed above the material receiving component 7 with its opening facing upward, the position of the oil seal skeleton is pre-adjusted by the thin-wall correction mechanism 9. When the thin-wall correction mechanism 9 corrects the thin-wall deformation of the oil seal skeleton, the thin-wall correction mechanism 9 pre-detects the degree of dent caused by the impact of the oil seal skeleton and applies a corresponding correction force to the side wall of the oil seal skeleton according to the deformation amplitude, correcting the elliptical, dented and other deformations of the oil seal skeleton to the standard roundness.

[0024] After correction, the electromagnetic vibration unit 4 continues to control the vibration of the linear material channel 5, causing the oil seal skeleton above the material support component 7 to continue moving to the clamping position. The PLC issues a clamping command, and the servo slide drives the gripper 3 to move above the linear material channel 5. The gripper 3's claw head extends into the inner hole of the oil seal skeleton, and the clamping force is adjusted through feedback from the torque sensor, flexibly fitting the inner wall to clamp the skeleton. The gripper 3 rises and moves horizontally along a preset path, avoiding the equipment interference area, and moves precisely above the mold cavity. The gripper 3 releases, and the skeleton falls smoothly into the cavity. After the material placement sensor detects and confirms that the material has been placed, the gripper 3 returns to its original position.

[0025] After the gripper 3 is reset, the PLC waits for the next material feeding permission signal from the host, while the linear feed chute 5 continues to feed the next skeleton, repeating the above steps.

[0026] The material support assembly 7 includes a material support plate 70 located on the inner wall of the connecting hole 6. Multiple pressure sensors 71 are installed on the top of the material support plate 70 and are distributed in a ring on the surface of the material support plate 70. A docking block 72 is slidably connected to the bottom side wall of the material support plate 70. A docking groove 73 is opened on the inner wall of the straight material channel 5 to engage with the docking block 72. The end of the docking block 72 near the docking groove 73 is trapezoidal. A spring sheet 74 is fixedly connected to the end of the docking block 72 near the material support plate 70. The end of the spring sheet 74 away from the docking block 72 is fixed to the inner wall of the material support plate 70.

[0027] The pressure sensors 71 distributed in a ring are adapted to the outer ring of the oil seal skeleton. Only when multiple pressure sensors 71 detect pressure signals will the PLC of the equipment housing 2 determine that the material is "completely dropped", thus avoiding the start of subsequent processes before the skeleton is placed stably.

[0028] In use, the spring plate 74 pushes the docking block 72 to insert into the inner wall of the docking groove 73, so that the material support plate 70 is fixed with the straight material trough 5. When the electromagnetic vibration unit 4 controls the vibration of the straight material trough 5, the vibration of the straight material trough 5 is transmitted to the material support plate 70. The material support plate 70 vibrates to cooperate in conveying the corrected oil seal skeleton to the rear end area of ​​the straight material trough 5.

[0029] The flipping mechanism 8 includes a detection ring 80 located on the side wall of the material support plate 70. The inner wall of the material support plate 70 is provided with a placement groove 81. The detection ring 80 is slidably connected to the inner wall of the placement groove 81. An airbag 82 is installed on the inner wall of the placement groove 81. The bottom of the material support plate 70 is provided with a flipping component 83 of a flipping oil seal skeleton. The airbag 82 is installed in an I-shape on the inner wall of the placement groove 81. The bottom end of the airbag 82 surrounds the bottom of the detection ring 80, and the top end of the airbag 82 surrounds the top of the material support plate 70. The initial state of the airbag 82 is that the bottom is inflated and the top is flat.

[0030] When the oil seal skeleton opening is upward, the oil seal skeleton moves above the material support plate 70 without squeezing the detection ring 80, the flipping part 83 is not triggered, and the thin wall correction mechanism 9 is activated to cooperate in correcting the side wall of the oil seal skeleton with the opening upward. When the oil seal skeleton opening is downward, the side wall of the oil seal skeleton presses against the detection ring 80, and the detection ring 80 compresses the bottom of the air bladder 82, causing the gas at the bottom of the air bladder 82 to be squeezed to the top of the air bladder 82. After the top of the air bladder 82 expands, it adjusts the position of the oil seal skeleton, making the oil seal skeleton coaxial with the material support plate 70. At this time, the flipping component 83 drives the material support plate 70 to descend. After the material support plate 70 is pulled down by the flipping component 83, the inclined edge of the mating block 72 and the inner wall of the mating groove 73 are pressed against each other, causing the mating hole compression spring 921 piece 74 to separate from the mating groove 73. After the plate 70 descends a preset distance (this distance is pre-designed according to the size of the oil seal skeleton), the material support plate 70 separates from the oil seal skeleton, and the material support plate 70 continues to descend to provide space for flipping the oil seal skeleton. After the flipping component 83 flips the oil seal skeleton, the flipping component 83 drives the material support plate 70 to move upward to the initial position to move the flipped oil seal skeleton to the shaping station. After the oil seal skeleton does not squeeze the detection ring 80, the air bag 82 is not squeezed, so that the air bag 82, under its own elastic force, re-presses the gas at the top of the air bag 82 into the bottom of the air bag 82.

[0031] The flipping component 83 includes a pneumatic telescopic rod 84 located at the bottom of the support plate 70. The pneumatic telescopic rod 84 is mounted on the surface of the equipment housing 2. An electromagnet 85 is mounted on one end of the pneumatic telescopic rod 84 near the support plate 70. An armature 86 is mounted at the center of the bottom of the support plate 70. A limit switch 87 is mounted at the bottom of the placement slot 81. The limit switch 87 is connected to the electromagnet 85. Support frames 88 are provided on both sides of the pneumatic telescopic rod 84. The support frames 88 are fixed to the surface of the equipment housing 2. A rotating shaft 89 is rotatably connected to the inner wall of the support frame 88. An electromagnet 810 is mounted on one end of the rotating shaft 89 near the pneumatic telescopic rod 84. A servo motor 811 is fixedly connected to one end of the rotating shaft 89. The servo motor 811 is mounted on the surface of the support frame 88.

[0032] After the oil seal skeleton is pressed down by the detection ring 80, the detection ring 80 squeezes the air bladder 82 and triggers the limit switch 87 at the bottom of the placement groove 81. The limit switch 87 controls the electromagnet 85 to be energized. The energized electromagnet 85 attracts the armature 86 at the bottom of the support plate 70, locking the support plate 70. The pneumatic telescopic rod 84 retracts, driving the electromagnet 85 to move. The electromagnet 85 then drives the support plate 70 to move. After the pneumatic telescopic rod 84 retracts to a fixed stroke, which is pre-designed according to the size of the oil seal skeleton, the oil seal skeleton moves between the two electromagnets 810. At this time, the electromagnets 810 are energized, so that the two electromagnets 810 attract the side wall of the oil seal skeleton. Meanwhile, the pneumatic telescopic rod 84 continues to drive the support plate 70 to move, causing the support plate 70 to separate from the oil seal skeleton. 4. After the space for flipping the oil seal skeleton is moved down to a sufficient level, the servo motor 811 drives the rotating shaft 89 to rotate. The rotating shaft 89 drives the electromagnet 810 to rotate 180°, thereby adjusting the oil seal skeleton from an opening-down position to an opening-up position. After the servo motor 811 is working, the pneumatic telescopic rod 84 extends, thereby pushing the support plate 70 closer to the oil seal skeleton. After the support plate 70 contacts the oil seal skeleton, the pneumatic telescopic rod 84 extends a fixed distance, and the electromagnet 810 is de-energized. As the pneumatic telescopic rod 84 continues to drive the support plate 70 to move upward, the oil seal skeleton can be moved upward until the support plate 70 moves to the initial position. At this time, the spring plate 74 pushes the docking block 72 to engage in the docking groove 73 of the linear material trough 5, and the electromagnet 85 is automatically de-energized so that the support plate 70 can vibrate together with the linear material trough 5.

[0033] The thin-wall correction mechanism 9 includes a fixed frame 90 located on top of the material support plate 70. The fixed frame 90 is fixedly connected to the equipment housing 2. A pneumatic telescopic rod 91 is installed on the surface of the fixed frame 90. An adjusting seat 92 is fixedly connected to one end of the pneumatic telescopic rod 91 near the material support plate 70. An electromagnet 93 is rotatably connected to the bottom of the adjusting seat 92. A conductive slip ring 94 is provided on the top of the electromagnet 93. The rotor of the conductive slip ring 94 is fixed to the top of the electromagnet 93. The stator of the conductive slip ring 94 is fixed to the inner wall of the adjusting seat 92. A rotating component 95 is provided on the inner wall of the adjusting seat 92 to drive the electromagnet 93 to rotate. Multiple arc plates 96 are provided on the outer side of the adjusting seat 92. The inner curvature of the arc plates 96 is the same as the outer curvature of the oil seal skeleton. An adjusting component 97 is provided on the inner wall of the adjusting seat 92 to drive the multiple arc plates 96 to move simultaneously. A correcting component 98 is provided on the adjusting seat 92 at the position corresponding to the arc plate 96 to abut against the inner side of the thin wall of the oil seal skeleton.

[0034] In use, the pneumatic telescopic rod 2 91 extends a fixed distance, and the pneumatic telescopic rod 2 91 drives the adjusting seat 92 to move to the inside of the opening of the oil seal skeleton. After the pneumatic telescopic rod 2 91 has moved, the electromagnet 4 93 is energized. The electromagnet 4 93 attracts the bottom area of ​​the oil seal skeleton. The adjusting component 97 simultaneously drives multiple arc plates 96 to move, so that the multiple arc plates 96 are attached to the outer ring surface of the oil seal skeleton. When the rotating component 95 drives the electromagnet 4 93 to rotate, the oil seal skeleton also rotates due to the attraction between the electromagnet 4 93 and the oil seal skeleton. The correcting component 98 corrects the side wall of the oil seal skeleton that it passes through, correcting the elliptical, concave and other deformations of the oil seal skeleton to the standard roundness.

[0035] The rotating component 95 includes a transmission cylinder 99 fixedly connected to the top of the electromagnet 93. A transmission gear ring 910 is fixedly connected to the outside of the transmission cylinder 99. A transmission gear 911 meshes with the outside of the transmission gear ring 910. One end of the transmission gear 911 is rotatably connected to the inner wall of the adjusting seat 92. The other end of the transmission gear 911 is fixedly connected to a drive motor 912. The drive motor 912 is installed on the inner wall of the adjusting seat 92.

[0036] When the rotating component 95 is working, the drive motor 912 drives the transmission gear 911 to rotate, the transmission gear 911 drives the transmission gear ring 910 to rotate, the transmission gear ring 910 drives the electromagnet 93 to rotate, and the rotating electromagnet 93 is powered through the conductive slip ring 94.

[0037] The adjusting component 97 includes a transmission rod 913 fixedly connected to the arc plate 96. An air storage chamber 914 is provided on the top of the adjusting seat 92. The air storage chamber 914 is connected to an external air source. A piston plate 915 is fixedly connected to one end of the transmission rod 913 near the air storage chamber 914. The piston plate 915 is slidably sealed to the inner wall of the air storage chamber 914. A return spring 916 is fixedly connected to the outer side of the piston plate 915. The end of the return spring 916 away from the piston plate 915 is fixed to the inner wall of the air storage chamber 914. The return spring 916 is initially in a stretched state.

[0038] Initially, an external air source fills the air storage chamber 914 with air, increasing the air pressure inside the air storage chamber 914 and thus pushing the piston plate 915 to slide along the inner wall of the air storage chamber 914. The return spring 916 is in a stretched state, and the piston plate 915 drives the arc plate 96 to move outward through the transmission rod 913. When the oil seal skeleton is being straightened, an external air source draws air into the air storage chamber 914. After the air pressure in the air storage chamber 914 decreases, multiple return springs 916 in a stretched state drive the arc plate 96 to move. The multiple arc plates 96 simultaneously clamp the outer ring of the oil seal skeleton to achieve radial positioning.

[0039] The corrector 98 includes a correction plate 917 that is slidably connected to the inner wall of the adjusting seat 92. Multiple correction plates 917 correspond to multiple arc plates 96. The end of the correction plate 917 near the arc plate 96 is arc-shaped. A connecting frame 918 is fixedly connected to the end of the correction plate 917 near the adjusting seat 92. The connecting frame 918 is slidably connected to the inner wall of the adjusting seat 92. An electromagnet 919 is installed on the inner wall of the adjusting seat 92. An armature 920 is fixedly connected to the end of the connecting frame 918 near the electromagnet 919. A compression spring 921 is fixedly connected to the outside of the connecting frame 918. The end of the compression spring 921 away from the connecting frame 918 is fixed to the inner wall of the adjusting seat 92. A control element 922 is provided on the outside of the correction plate 917 to adjust the squeezing force between the correction plate 917 and the oil seal skeleton according to the degree of deformation of the oil seal skeleton.

[0040] When multiple arc plates 96 contract, the axial direction of the oil seal skeleton is collinear with the axial direction of the adjusting seat 92. At this time, the correction plate 917 is in contact with the inner ring sidewall of the oil seal skeleton. When the oil seal skeleton rotates, the control component 922 controls the current of the electromagnet 919 according to the degree of deformation of the oil seal skeleton. The greater the degree of deformation of the oil seal skeleton, the greater the current of the electromagnet 919, and the greater the attraction force of the electromagnet 919 on the armature 920, so that the distance between the correction plate 917 and the oil seal skeleton is smaller. Multiple correction plates 917 cooperate with each other to perform multi-level correction on the area of ​​the oil seal skeleton with a large degree of deformation, correcting the elliptical, concave and other deformations of the skeleton to the standard roundness, and avoiding the excessive compression angle between the correction plate 917 and the deformation area of ​​the oil seal skeleton, which would cause secondary deformation of the oil seal skeleton.

[0041] The control component 922 includes a detection rod 923 located outside the calibration plate 917. A synchronizing rod 924 is fixedly connected to one end of the detection rod 923 near the adjusting seat 92. The synchronizing rod 924 is slidably connected to the inner wall of the adjusting seat 92. A sliding rheostat 925 is installed on the inner wall of the adjusting seat 92. The sliding rheostat 925 is connected in series with the circuit containing the adjacent electromagnet 919. The synchronizing rod 924 is fixed to the slider of the sliding rheostat 925. A reset spring 926 is fixedly connected to the outside of the synchronizing rod 924. The end of the reset spring 926 away from the synchronizing rod 924 is fixed to the inner wall of the adjusting seat 92. The greater the distance that the synchronizing rod 924 slides into the inner wall of the adjusting seat 92, the smaller the resistance of the sliding rheostat 925.

[0042] When the deformation area of ​​the oil seal skeleton presses against the detection rod 923 during use, the detection rod 923 drives the synchronous rod 924 to move. When the synchronous rod 924 slides on the inner wall of the adjusting seat 92, it drives the slider of the sliding rheostat 925 to move. This makes the synchronous rod 924 slide into the inner wall of the adjusting seat 92 a larger distance, and the resistance of the sliding rheostat 925 a smaller value. At this time, the current of the electromagnet 919 is larger, and thus the attraction of the electromagnet 919 to the armature 920 is greater.
