[0002] With the development of the economic society and the progress of science and technology, the manufacturing industry has gradually realized mechanized production. Among them, the sealing ring is a commonly used component on mechanical equipment. Due to the small structure of the sealing ring itself, the manual picking and placing method is still mostly used in the manufacturing and assembly processes of the sealing ring, resulting in high labor intensity and low production efficiency. And the existing sealing ring picking devices have the following problems: 1. The sealing rings placed in the working position groove may be multiple stacked ones instead of a single one, which affects the accuracy of picking up a single sealing ring. 2. The stability of the sealing ring during the picking process is not high, and it may deviate, resulting in the failure of picking up the ring and affecting the picking efficiency. Therefore, it is necessary to develop a device for expanding and picking up sealing rings to solve the above problems. Summary of the Invention

[0019] The following further describes the implementation manners of the present invention with reference to the accompanying drawings.

[0020] As shown in the figure, a seal ring expanding and picking device includes an adjacent support ring mechanism and a flattening mechanism. The support ring mechanism includes a support ring frame 1, a support ring power device 2, and a support ring box 3. The support ring box 3 is located above the support ring power device 2, and both the support ring power device 2 and the support ring box 3 are connected to the support ring frame 1 through a mounting plate 4. The top of the support ring frame 1 is provided with an adjusting lead screw, the top of the adjusting lead screw is provided with an adjusting knob 5, and the nut sleeve on the adjusting lead screw is connected to the mounting plate 4. Rotating the adjusting knob 5 can make the mounting plate 4 move up and down along the adjusting lead screw. The lifting rod of the support ring power device 2 is connected to the connecting block 6. The support ring power device 2 can be a cylinder. The connecting block 6 is provided with a thrust rod 7, and a slide block 8 and a spring 9 are sleeved on the thrust rod 7. The spring 9 is located between the slide block 8 and the connecting block 6.

[0021] The ring support box 3 comprises a fixed block 301 and a cover 302 located atop the fixed block 301. The fixed block 301 includes a lifting channel for the slider 8. The top surface of the cover 302 is provided with a work station slot 10, which consists of a semicircular portion and a rectangular portion. The rectangular portion has an opening at one end, near the flattening mechanism, through which the sealing ring enters the work station slot 10 and is ultimately placed in the semicircular portion. A through hole 11 is located at the center of the semicircular portion, corresponding to the push rod 7. Around the through hole 11 are radially arranged relief grooves 12, each extending longer than the radius of the semicircular portion. Both ends of the semicircular portion are connected to a fiber optic channel 13. A fiber optic transmitter 14 and a fiber optic sensor 15 are located on either side of the fixed block 301, aligned with the fiber optic channel 13. The fiber optic sensor 15 senses the presence of a fiber optic signal and transmits the signal to a controller to determine whether a sealing ring is present in the work station slot 10. A spreading rod 16 is provided in the cover body 302, corresponding to the clearance groove 12. The spreading rod 16 has a tail at one end away from the other, which is movably connected to the connecting seat 17 on the top surface of the slider 8 via a connecting shaft. The radius of the circle where the end of the tail is located is larger than the radius of the lifting channel, so that the spreading rod 16 can be restricted by the top surface of the fixed block 301 and will not fall into the lifting channel. A protrusion is provided on the top surface of the other end of the spreading rod 16. The radius of the circle where the end of the protrusion is located is smaller than the radius of the through hole 11. The protrusion can apply a radial force to the sealing ring. At the same time, the protrusion and the spreading rod 16 form a step, ensuring that the sealing ring is stably located at the step when it is spread, thereby ensuring the stability of the sealing ring. When the push rod 7 moves to the spreading rod 16, the push rod 7 can push the spreading rod 16 outward, causing the spreading rod 16 to rotate with the connecting shaft as the rotation center.

[0022] The flattening mechanism includes a bracket 18, topped with a fixed frame. The bracket's top plate 20 is connected parallel to a pressure plate 19 via a drive assembly. The pressure plate 19 is positioned above the through-hole 11. The drive assembly includes movable rods 21, a movable plate 22, a movable block 23, and a push-pull cylinder 24. There are four movable rods 21, symmetrically positioned on either side of the bracket's top plate 20. The movable plates 22 are positioned below the bracket's top plate 20. Each movable rod 21 is rotatably connected to the top plate 20. One end of each movable rod 21 is rotatably connected to the pressure plate 19, while the other end is rotatably connected to the movable plate 22. The connection point between the movable rod 21 and the top plate 20 serves as a fulcrum. The distance from the connection point between the movable rod 21 and the pressure plate 19 to the fulcrum is greater than the distance from the connection point between the movable rod 21 and the movable plate 22 to the fulcrum. Utilizing the principle of leverage, when the expansion rod 16 contacts the pressure plate 19, the expansion rod 16 can easily lift the pressure plate 19, preventing a violent collision between the pressure plate 19 and the expansion rod 16, which would affect the service life of the expansion rod 16. The end of the movable plate 22 away from the support ring mechanism is connected to the movable block 23 via a first movable shaft. The movable block 23 is hinged to the push-pull rod of the push-pull cylinder 24. The two ends of the push-pull cylinder 24 are connected to the support seat on the bracket 18 via a second movable shaft and a third movable shaft, respectively. When the push-pull rod on the push-pull cylinder 24 is pushed out, the push-pull rod drives the movable plate 22 to translate forward through the movable block 23, and the moving trajectory is a curve with the fulcrum as the center of the circle. The movement of the movable plate 22 causes the movable rod 21 to rotate clockwise with the fulcrum as the rotation center, and the rotation of the movable rod 21 drives the pressure plate 19 to translate backward accordingly, and the moving trajectory is a curve with the fulcrum as the center of the circle. At this time, the pressure plate 19 is above the through hole 11 and staggered with the through hole 11; when the push-pull rod on the push-pull cylinder 24 is retracted, the push-pull rod drives the movable plate 22 to translate backward through the movable block 23, and the moving trajectory is a curve with the fulcrum as the center of the circle. The movement of the movable plate 22 causes the movable rod 21 to rotate counterclockwise with the fulcrum as the rotation center, and the rotation of the movable rod 21 drives the pressure plate 19 to translate forward accordingly, and the moving trajectory is a curve with the fulcrum as the center of the circle. At this time, the pressure plate 19 is directly above the through hole 11.

[0023] Before use, retract the push-pull rod on the push-pull cylinder 24, move the pressure plate 19 to directly above the through hole 11, and change the installation height of the mounting plate 4 on the support ring frame 1 according to the size of the sealing ring, so that the gap between the pressure plate 19 and the work station slot 10 can only allow one sealing ring to pass through. In this embodiment, the installation height of the mounting plate 4 is changed by rotating the adjustment knob 5. When in use, the sealing ring enters the work station slot 10 through the opening. After the optical fiber sensor 15 senses that the sealing ring is in place, the lifting rod on the support ring power device 2 is pushed out, and the lifting rod drives the push rod 7 to move upward through the connecting block 6. The slider 8 moves up with the push rod 7. When the connecting seat 17 on the top of the slider 8 contacts the top of the cover body 302, the spring 9 begins to compress and deform, and the push rod 7 continues to move upward. After the push rod 7 contacts the opening rod 16, the opening rod 16 is pushed open to the four sides. When the opening rod 16 is opened, the sealing ring will be opened, and the step formed by the protrusion and the opening rod 16 will exert a lifting force on the sealing ring to ensure the stability of the sealing ring on the opening rod 16. When the opening rod 16 opens the sealing ring, it will also move the sealing ring up a distance and contact the pressure plate 19. At this time, the pressure plate 19 applies pressure to the sealing ring to press the sealing ring on the opening rod 16, effectively preventing the sealing ring from running off and causing the ring to fail to be removed. After the material picking rod is removed, the push-pull rod on the push-pull cylinder 24 is retracted, causing the pressure plate 19 to return to the top of the through hole 11, thereby completing the material picking action of the sealing ring.

[0024] Therefore, the present invention adopts the sealing ring of the above structure to open the material taking device, which effectively solves the problem of the sealing ring running off during the material taking process and improves the accuracy and efficiency of the ring taking.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
