Description
Technical Field
[0001] This utility model relates to an automatic feeding mechanism for sealing rings. Background Technology
[0002] Currently, the assembly of sealing rings is mostly done manually, which is time-consuming, labor-intensive, and severely impacts assembly efficiency. In automated production, the flexible and easily deformable nature of sealing rings makes gripping them on automated production lines challenging. Existing sealing ring feeding methods use vibrating feeders, but sealing rings are difficult for robotic arms or other gripping devices to accurately pick up from these feeders. Furthermore, the variety of sizes and models of sealing rings further increases the difficulty of gripping. Therefore, it is necessary to design an automated feeding mechanism that can easily grip various types of sealing rings. Utility Model Content
[0003] The purpose of this invention is to provide an automatic feeding mechanism for sealing rings to solve the technical problems mentioned in the background section.
[0004] The technical solution to achieve the purpose of this utility model is: an automatic feeding mechanism for sealing rings, including a frame, a sealing ring feeding rack on one side of the frame, a sealing ring gripping component and a conveying component for driving the sealing ring gripping component to move on the frame; a sealing ring support frame with adjustable diameter is provided on the sealing ring feeding rack, the sealing ring is sleeved on the sealing ring support frame, and the sealing ring gripping component grips the sealing ring for feeding.
[0005] Furthermore, the sealing ring feeding rack includes a fixed bracket and a feeding base plate. The feeding base plate is fixedly connected to the machine frame through the fixed bracket. The sealing ring support frame includes a support base and a support column. The support column is disposed in the inner ring of the sealing ring and is connected to the support base. The support base is fixed on the feeding base plate.
[0006] Furthermore, at least three support columns are evenly arranged along the inner ring of the sealing ring. The sealing ring gripping assembly includes a chuck seat, a jaw, and a jaw driving device that drives the jaw to move radially along the chuck seat. When the sealing ring gripping assembly grips the sealing ring, the jaw is located in the gap between two adjacent support columns and opens the sealing ring.
[0007] Furthermore, the support base is provided with a radially arranged sliding groove, and the bottom of the support column is provided with a slider that matches the sliding groove.
[0008] Furthermore, the sealing ring feeding rack is equipped with a lifting platform and a lifting mechanism. The lifting mechanism is fixed on a fixed bracket. The lifting platform is provided with a through hole for the support column to pass through. After the sealing rings are fitted onto the sealing ring support frame, they are stacked vertically on the lifting platform. The lifting mechanism drives the lifting platform to rise and fall.
[0009] Furthermore, the through hole at least partially corresponds to the vertical projection of the groove.
[0010] Furthermore, a height sensor for detecting the height of the sealing ring is provided on the side of the frame near the sealing ring feeding rack.
[0011] Furthermore, the conveying assembly includes an X-axis moving mechanism, a Y-axis moving mechanism, a Z-axis moving mechanism, an X-axis moving crossbeam, a Y-axis moving seat, and a Z-axis lifting seat. The X-axis moving mechanism drives the X-axis moving crossbeam to move. The Y-axis moving mechanism and the Y-axis moving seat are mounted on the X-axis moving crossbeam. The Y-axis moving mechanism drives the Y-axis moving seat to move. The Z-axis moving mechanism and the Z-axis lifting seat are mounted on the Y-axis moving seat.

[0030] (Example 1)
[0031] See Figure 1-3 The automatic feeding mechanism for sealing rings in this embodiment includes a frame 1, a sealing ring feeding rack 2 is provided on one side of the frame 1, a sealing ring gripping component 3 and a conveying component for driving the sealing ring gripping component 3 to move are provided on the frame 1; a sealing ring support frame 4 with adjustable diameter is provided on the sealing ring feeding rack 2, the sealing ring is sleeved on the sealing ring support frame 4, and the sealing ring gripping component 3 grips the sealing ring for feeding.
[0032] Specifically, the sealing ring feeding rack 2 includes a fixed bracket 2-1 and a feeding base plate 2-2. The feeding base plate 2-2 is fixedly connected to the frame 1 through the fixed bracket 2-1. The sealing ring support frame 4 includes a support base 4-1 and a support column 4-2. The support column 4-2 is set in the inner ring of the sealing ring. The support column 4-2 is connected to the support base 4-1. The support base 4-1 is fixed on the feeding base plate 2-2.
[0033] At least three support columns 4-2 are evenly arranged along the inner ring of the sealing ring. The sealing ring gripping assembly 3 includes a chuck seat 3-1, jaws 3-2, and a jaw drive device that drives the jaws 3-2 to move radially along the chuck seat 3-1. When the sealing ring gripping assembly 3 grips the sealing ring, the jaws 3-2 are located in the gap between two adjacent support columns 4-2, thus opening the sealing ring. In this embodiment, three support columns 4-2 are provided, and the sealing ring gripping assembly 3 adopts a three-jaw pneumatic chuck. Simultaneously driving the three jaws 3-2 to move radially along the chuck seat 3-1 through the jaw drive device is a relatively mature technology in the industry and will not be elaborated here.
[0034] The support base 4-1 has a radially arranged groove 4-1-1, and the bottom of the support column 4-2 has a slider 4-2-1 that matches the groove 4-1-1. The slider 4-2-1 at the bottom of the support column 4-2 allows the support column 4-2 to move radially. This design makes adjusting the diameter of the sealing ring support frame 4 simple and quick, facilitating rapid switching between production tasks of different specifications of sealing rings.
[0035] The sealing ring feeding rack 2 is equipped with a lifting platform 5 and a lifting mechanism 6. The lifting mechanism 6 is fixed on the fixed bracket 2-1. The lifting platform 5 is provided with a through hole 5-1 for the support column 4-2 to pass through. After the sealing rings are fitted onto the sealing ring support frame 4, they are stacked vertically on the lifting platform 5. The lifting mechanism 6 drives the lifting platform 5 to rise and fall.
[0036] The through hole 5-1 is at least partially aligned with the vertical projection of the slide groove 4-1-1 to prevent the support column 4-2 from being blocked by the lifting platform 5 when the position is adjusted.
[0037] A height sensor 7 for detecting the height of the sealing rings is installed on the side of the frame 1 near the sealing ring feeding rack 2. When the top sealing ring is removed, the lifting mechanism 6 will automatically lift the lifting platform 5 to bring the next sealing ring to the appropriate position, thus realizing a continuous and automated feeding process.
[0038] The conveying assembly includes an X-axis moving mechanism 8, a Y-axis moving mechanism 9, a Z-axis moving mechanism 10, an X-axis moving beam 11, a Y-axis moving seat 12, and a Z-axis lifting seat 13. The X-axis moving mechanism 8 drives the X-axis moving beam 11 to move. The Y-axis moving mechanism 9 and the Y-axis moving seat 12 are mounted on the X-axis moving beam 11, and the Y-axis moving mechanism 9 drives the Y-axis moving seat 12 to move. The Z-axis moving mechanism 10 and the Z-axis lifting seat 13 are mounted on the Y-axis moving seat 12, and the Z-axis moving mechanism 10 drives the Z-axis lifting seat 13 to rise and fall. The sealing ring gripping assembly 3 is mounted on the Z-axis lifting seat 13. In this embodiment, the X-axis moving mechanism 8, the Y-axis moving mechanism 9, the Z-axis moving mechanism 10, and the lifting mechanism 6 all adopt linear screw modules.
[0039] The Z-axis lifting seat 13 is equipped with a spring seat 13-1 and a mounting seat 13-2. The sealing ring gripping assembly 3 is mounted on the mounting seat 13-2. The mounting seat 13-2 is slidably connected to the Z-axis lifting seat 13 along the Z-axis. A spring is provided between the spring seat 13-1 and the mounting seat 13-2 to provide a buffer for the sealing ring gripping assembly 3. In the event of an accidental collision or overload, the spring can absorb the impact force and protect the equipment from damage. It also increases the smoothness of the gripping action and reduces the risk of damage to the sealing ring.
[0040] Of course, in order to stack more sealing rings, multiple sealing ring support frames 4 can be set up, and each sealing ring support frame 4 corresponds to a height sensor 7.
[0041] The working principle of this utility model is as follows: The sealing ring is sleeved on the sealing ring support frame 4, and the support column 4-2 is set in the inner ring of the sealing ring, with a gap in the middle of the support column 4-2. When the claw 3-2 grasps, it enters through the gap between the support columns 4-2, and then the claw drive device drives it to move radially outward to open the sealing ring for grasping. After the conveying component moves the sealing ring grasping component 3 into position, the claw drive device drives the claw 3-2 to move radially inward to release the sealing ring. The position of the uppermost sealing ring is detected by the height sensor 7. When the previous sealing ring is grasped, the lifting mechanism 6 drives the lifting platform 5 to rise, moving the next sealing ring to the grasping position. When other sizes of sealing rings need to be grasped, the slider 4-2-1 at the bottom of the support column 4-2 is moved to adjust the position of the support column 4-2 on the support base 4-1 to adapt to the size of the sealing ring.
[0042] The sealing ring of this utility model is sleeved on the sealing ring support frame 4, which facilitates the sealing ring gripping component 3 to grip it. The diameter of the sealing ring support frame 4 is adjustable, which can adapt to sealing rings of different sizes. This design enables the equipment to process a variety of sealing rings, improving the versatility of the equipment and the flexibility of the production line.
[0043] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
