[0042] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0043] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0044] In the description of this invention, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features or their sequential relationship.

[0045] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0046] Reference Figures 1 to 5 The air-sealing ring assembly mechanism of this invention includes a base frame 100 and an operating platform 110 mounted on the base frame 100. The operating platform 110 is rotatably mounted on the base frame 100 around its own axis, and a fixing device is provided on the upper surface of the operating platform 110. The fixing device is used to fix the position of the projectile to facilitate the installation of the air-sealing ring. The operating platform 110 is circular, and multiple fixing devices are provided. The multiple fixing devices are evenly spaced around the outer periphery of the operating platform 110, that is, multiple projectiles are generally placed on the operating platform 110 during operation to improve work efficiency.

[0047] It should be noted that the base frame 100 is also equipped with a loading device and a unloading device. The loading device is used to supply the projectile to the fixing device on the operating table 110, and the unloading device is used to remove the projectile with the sealing ring installed from the fixing device, but these are not shown in the attached drawings. The loading and unloading devices can be operated by conventional robotic arms, and the specific placement of the robotic arms can be arranged according to actual needs.

[0048] In some embodiments of the present invention, the operating table 110 rotates clockwise or counterclockwise around its central axis, but only in one direction, that is, it can only rotate clockwise or counterclockwise, and does not need to have a reverse rotation function. Figure 1 , Figure 2For example, in this embodiment, the operating table 110 rotates counterclockwise. Along the rotation direction of the operating table 110, a first working device 300, a second working device 400, and a third working device 500 are sequentially arranged around the outer periphery of the operating table 110. That is, the projectile passes through the first working device 300, the second working device 400, and the third working device 500 sequentially to complete the installation of the air-sealing ring. The first working device 300 is used to place the air-sealing ring supplied by the feeding device 200 onto the projectile located on the operating table 110. The second working device 400 is used to apply silicone grease to the outer periphery of the projectile. The third working device 500 is used to push the air-sealing ring to the set position of the projectile. Specifically, the first working device 300 only places the air-sealing ring on the upper part of the projectile. When the projectile passes through the second working device 400, the second working device 400 applies silicone grease to the outer periphery of the projectile, specifically below the air-sealing ring, so that the third working device 500 can push the air-sealing ring down to the set position.

[0049] It should be noted that the first working device 300, the second working device 400, and the third working device 500 are all installed on the base frame 100.

[0050] It is conceivable that, along the rotation direction of the operating table 110, the second working device 400, the first working device 300, and the third working device 500 could be sequentially arranged on the outer periphery of the operating table 110. That is, silicone grease could be applied to the outer periphery of the projectile first, and then the sealing ring could be installed and pushed to the set position.

[0051] In some embodiments of the present invention, the air-sealing ring assembly mechanism further includes a feeding device 200, a detection device 600, a gripping device 700, and a waste bin 800. The feeding device 200, detection device 600, gripping device 700, and waste bin 800 are all mounted on the base frame 100. The feeding device 200 supplies air-sealing rings, the detection device 600 detects the air-sealing rings, and the gripping device 700 transfers the air-sealing rings from the feeding device 200 to the detection device 600. A first working device 300 grips the air-sealing rings on the detection device 600 and places them onto the projectile located on the operating table 110. The first working device 300 is positioned between the detection device 600 and the operating table 110, and the waste bin 800 is positioned close to the first working device 300.

[0052] According to the embodiment of the present invention, the air-sealing ring assembly mechanism can automatically install the air-sealing ring onto the projectile body by reasonably arranging the first working device 300, the second working device 400 and the third working device 500 on the outer periphery of the operating table 110, thereby effectively improving efficiency and reducing labor costs.

[0053] In an embodiment of the present invention, reference is made to Figure 1As shown, the air-sealing ring is a circular ring with three radially extending arms, which are evenly spaced around the outer circumference of the air-sealing ring. Furthermore, the circular portion of the air-sealing ring has a notch, allowing it to be pulled horizontally outward along the radial direction of the rod-shaped structure when fitted onto it. The feeding device 200 in this embodiment includes multiple rod-shaped structures, evenly spaced around the circumference, each fitted with an air-sealing ring. Each rod-shaped structure is vertically arranged and fitted with multiple air-sealing rings, which are stacked vertically on the same rod-shaped structure. The gripping device 700 in this embodiment includes a rotating cylinder and a telescopic cylinder to grip the air-sealing rings fitted onto the rod-shaped structure and transfer them to the detection device 600.

[0054] In a specific embodiment of the present invention, the gripping device 700 includes a rotating cylinder, a lifting cylinder, and a horizontal telescopic cylinder. The lifting cylinder is mounted on the rotating cylinder, and the horizontal telescopic cylinder is mounted on the movable end of the lifting cylinder.

[0055] In some embodiments of the present invention, the detection device 600 includes a placement cylinder 610, a pressure plate 620, and a camera 630. The placement cylinder 610 is used to place the air-sealing ring, the pressure plate 620 is disposed above the placement cylinder 610 and is movable relative to the placement cylinder 610, and the camera 630 is disposed above the pressure plate 620. (See reference...) Figure 1 , Figure 3 As shown, the top of the placement cylinder 610 is provided with a slot 611 for the air-sealing ring to be inserted, and the pressure plate 620 is provided with a through hole 621 for the placement cylinder 610 to pass through; the pressure plate 620 can move horizontally and rise vertically relative to the placement cylinder 610. Specifically, the inner ring of the air-sealing ring is provided with a chamfer, and the detection device 600 is used to detect whether the chamfer of the air-sealing ring meets the requirements.

[0056] In some specific embodiments of the present invention, the placement cylinder 610 is a cylindrical structure with three slots 611 at its top, evenly spaced around the circumference. When the air-sealing ring is placed on top of the placement cylinder 610, its three extension arms are respectively inserted into the three slots 611. The inner diameter of the through hole 621 is slightly larger than the outer diameter of the placement cylinder 610, but smaller than the length of the extension arms. Therefore, when the through hole 621 is concentric with the placement cylinder 610 and descends relative to the placement cylinder 610, the pressure plate 620 can press down on the three extension arms to undergo elastic deformation, causing the central annular structure of the air-sealing ring to partially flip, thus better exposing the chamfer and facilitating the shooting and identification by the camera 630.

[0057] Furthermore, the pressure plate 620 is connected to a horizontal telescopic cylinder and a vertical lifting cylinder. The horizontal telescopic cylinder is used to make the pressure plate 620 misaligned with the placement cylinder 610, thereby facilitating the placement of the air-sealing ring. The vertical lifting cylinder is used to drive the pressure plate 620 to rise and fall, thereby exposing the chamfer of the air-sealing ring.

[0058] In some embodiments of the present invention, the detection device 600 further includes a light source 640, which is disposed between the imager 630 and the placement tube 610. Specifically, see... Figure 3 As shown, the camera is the image capture device 630, and the ring light source 640 is a circular light source 640. A through-hole is located at the center of the ring light source 640, and the camera's lens module is concentrically positioned with the through-hole in the center of the ring light source 640. The ring light source 640 provides supplementary lighting for the closed-loop ring, allowing for a clearer capture of the chamfered edge of the closed-loop ring.

[0059] In some embodiments of the present invention, the detection device 600 can issue a first detection signal and a second detection signal based on the detection result. The first working device 300 is electrically connected to the detection device 600. In response to the first detection signal, the first working device 300 places the air-sealing ring grasped from the detection device 600 onto the projectile of the operating table 110. In response to the second detection signal, the first working device 300 transfers the air-sealing ring grasped from the detection device 600 into the waste bin 800. Specifically, the detection device 600 photographs the chamfer of the air-sealing ring and matches it with a preset chamfer of the air-sealing ring. If the photographed chamfer of the air-sealing ring meets the standard, a first detection signal is issued; if the photographed chamfer of the air-sealing ring does not meet the standard, a second detection signal is issued. The first detection signal indicates that the photographed air-sealing ring is qualified, and the second detection signal indicates that the photographed air-sealing ring is unqualified.

[0060] In some specific embodiments of the present invention, reference is made to... Figure 5 As shown, the first working device 300 includes a first rotary cylinder 310, a first gripper 330, and a second gripper 340, which are arranged opposite to each other. Rotation of the first rotary cylinder 310 can cause the first gripper 330 and the second gripper 340 to exchange positions. Specifically, the first gripper 330 and the second gripper 340 are collinear, and the single rotation angle of the first rotary cylinder 310 is ninety degrees. (Refer to...) Figure 1 As shown, two waste bins 800 are provided, and the two waste bins 800 are respectively located on opposite sides of the first working device 300. When the first gripper 330 or the second gripper 340 grabs the air-sealing ring of the detection device 600, if the first working device 300 responds to the second detection signal, the first gripper 330 or the second gripper 340 will drop the grabbed air-sealing ring into the waste bin 800.

[0061] It is conceivable that there may only be one waste bin (800).

[0062] In some embodiments of the present invention, the first working device 300 further includes a first lifting cylinder 320, which is mounted on the first rotating cylinder 310. The first gripper 330 and the second gripper 340 are both mounted on the movable end of the first lifting cylinder 320. (See also...) Figure 1 , Figure 2 As shown, since the projectile has a certain height, a first lifting cylinder 320 is provided to facilitate the placement of the air-sealing ring on the projectile. At the same time, since the air-sealing ring is partially embedded in the slot 611 of the placement cylinder 610, after the first gripper 330 or the second gripper 340 holds the air-sealing ring, the first gripper 330 or the second gripper 340 must rise to a certain height in order to remove the air-sealing ring from the placement cylinder 610.

[0063] In some embodiments of the present invention, reference is made to... Figure 2 , Figure 4 As shown, the second working device 400 includes a grease injector 410, which is connected to a horizontal telescopic cylinder and a vertical lifting cylinder to facilitate grease injection onto the outer circumferential surface of the projectile.

[0064] In some embodiments of the present invention, the third working device 500 includes a third lifting cylinder 510, a third horizontal cylinder 520, and a working arm 530. The third horizontal cylinder 520 is mounted on the movable end of the third lifting cylinder 510, and the working arm 530 is mounted on the movable end of the third horizontal cylinder 520. The end of the working arm 530 is provided with an arc-shaped groove 531. (Refer to...) Figure 2 , Figure 4 As shown, the curvature of the arc groove 531 is slightly larger than the outer diameter of the projectile, which makes it easier to push the air-sealing ring downward.

[0065] The working process of the air-sealing ring assembly mechanism in this embodiment of the invention is as follows:

[0066] 1. The feeding device places the projectile onto the fixing device on the operating table 110;

[0067] 2. The control panel 110 rotates to rotate the projectile to the position of the first working device 300;

[0068] 3. The gripping device 700 grips the air-sealing ring from the feeding device 200 and sends the air-sealing ring to the detection device 600. After the detection device 600 detects that the air-sealing ring is qualified, it sends out the first detection signal.

[0069] 4. The first working device 300 grabs the air-sealing ring on the detection device 600 and puts it on the projectile body;

[0070] 5. The projectile with the sealing ring is rotated to the position of the second working device 400 by the operating table 110. The second working device 400 applies silicone grease to the outer periphery of the projectile with the sealing ring.

[0071] 6. The operating table 110 continues to rotate to drive the projectile to the position of the third working device 500. The working arm 530 of the third working device 500 extends to push the gas-sealing ring fitted on the upper part of the projectile to the set position of the projectile, thus completing the installation of the gas-sealing ring.

[0072] 7. The unloading device removes the projectile after the air-sealing ring has been installed and sends it to the next operating station.

[0073] It is important to understand that steps 1 and 3 are performed simultaneously. The grabbing device 700 and the detection device 600 do not start operating only after the projectile reaches the first working position in step 2. Furthermore, in step 3, if the air-sealing ring detected by the detection device 600 is unqualified, a second detection signal will be issued, which will cause the air-sealing ring grabbed by the first working device 300 in step 4 to be discarded into the waste bin 800.
