[0046] Before explaining in detail the sealing ring assembly device provided in the embodiment of the present application, the relevant scenarios are first explained.

[0047] The breathing tube set includes a soft tube body 8 and a connector 9. The connector 9 is a double-head structure, and the diameters of the two ends can be the same or different. In order to enable the tube body 8 to be connected to other equipment or other tubes, one end of the connector 9 usually needs to be inserted into the tube body 8, and the other end is used to connect other equipment or tubes. The form of simply plugging in cannot guarantee the airtightness of the plug-in connection between the two, so a sealing ring 10 needs to be installed at the joint between the tube body 8 and the connector 9.

[0048] Currently, the assembly operation of the sealing ring 10 is all done manually, which has low production efficiency and causes fatigue to workers due to long working hours. Manual assembly of the ring is prone to quality problems, making it difficult to control the quality. Therefore, it is necessary to design a device specifically for assembling the sealing ring 10 between the pipe body 8 and the connector 9 to avoid the above-mentioned disadvantages caused by manual assembly.

[0049] The sealing ring assembly equipment provided in the embodiment of the present application is explained in detail below.

[0050] The present embodiment provides a sealing ring assembly device, including a support body 1, an expansion mechanism 2, a linear drive mechanism 3 and a pressing mechanism 4, the support body 1 is used to support the expansion mechanism 2 and the pressing mechanism 4, and the pressing mechanism 4 is located on one side of the expansion mechanism 2; the linear drive mechanism 3 connects the expansion mechanism 2 and the support body 1, and the linear drive mechanism 3 is used to drive the expansion mechanism 2 to move in a direction close to or away from the pressing mechanism 4; the expansion mechanism 2 includes a support claw 21, an intermediate connecting rod structure 22 and a driving structure 23, the number of the support claws 21 is more than three and is distributed along the circumferential direction, all the support claws 21 surround a cannula placement space 5, each support claw 21 is connected to the driving structure 23 through the intermediate connecting rod structure 22, and when the driving structure 23 is actuated, it can drive the support claw 21 to open to expand the sealing ring 10 and can drive the support claw 21 to reset; the pressing mechanism 4 is used to press the sealing ring 10 to fit tightly against the pipe fitting extending into the cannula placement space 5, so that the support claw 21 is separated from the sealing ring 10 through the linear drive mechanism 3.

[0051] See 4 and Figure 5 The support claws 21 are distributed along the circumferential direction and enclose a cannula placement space 5. The movement of each support claw 21 in a direction away from the central axis of the cannula placement space 5 is called support claw opening, and the movement of each support claw 21 in a direction close to the central axis of the cannula placement space 5 is called support claw closing or support claw resetting. The state in which the support claw 21 is opened to the maximum of the cannula placement space 5 is called the first state, and the state in which the support claw 21 is closed to the minimum of the cannula placement space 5 is called the second state.

[0052] The sealing ring assembly device of this embodiment is used as follows: when in use, the sealing ring 10 is manually placed on the supporting claw 21 in the second state, and the driving structure 23 is controlled to operate, and the supporting claw 21 is driven to open through the intermediate connecting rod structure 22, so that the sealing ring 10 is stretched open until the supporting claw 21 is in the first state. One end of the connector 9 is manually inserted into the tube body 8, and the tube body 8 and the connector 9 are inserted into the insertion tube placement space 5, see Figure 1 and Figure 3 , schematically showing that the tube body 8 and the connector 9 are placed in the cannula placement space 5. The control driving structure 23 is activated, and the supporting claw 21 moves in the reset direction until it is in the second state, see Figure 1 and Figure 2 , indicating that the support claw 21 is in the second state. The pressing mechanism 4 is controlled to move, and the pressing mechanism 4 presses the sealing ring 10 to close the tube body 8 and the connector 9 extending into the cannula placement space 5, see Figure 2 , Figure 2 The figure shows a pressing mechanism 4 in a state of pressing the sealing ring 10. Then the linear drive mechanism 3 is controlled to move, driving the opening mechanism 2 to move away from the pressing mechanism 4, so that the supporting claw 21 is separated from the sealing ring 10, and the sealing ring 10 is sleeved at the junction of the tube body 8 and the connector 9. Then the pressing mechanism 4 moves in the reset direction until it moves to the initial state, and the pressing of the sealing ring 10 is cancelled. At this time, the tube body 8 and the connector 9 with the sealing ring 10 are manually taken out from the cannula placement space 5. The linear drive mechanism 3 is controlled to move, driving the opening mechanism 2 to move toward the pressing mechanism 4 until it moves to the initial state. Then according to the above content, another sealing ring 10 is manually sleeved on the supporting claw 21, and the sealing ring 10 is assembled on the next tube body 8 and the connector 9.

[0053] From the above, it can be seen that the pressing mechanism 4 is mainly used to place and press the sealing ring 10 so that the supporting claw 21 can be separated from the sealing ring 10. Therefore, when the pressing mechanism 4 presses the sealing ring 10, it should avoid pressing the supporting claw 21. Preferably, there are more than one pressing mechanism 4.

[0054] The effect of the sealing ring assembly equipment provided in this embodiment is that it replaces manual operation. Manual operation only requires inserting the sealing ring 10 into the expansion component and inserting and removing the tube body 8 and the connector 9, which greatly improves the efficiency of assembly. In addition, the assembled sealing ring 10 avoids quality problems such as skewing of the two ends of the sealing ring 10 or wrinkles caused by manual installation, thereby ensuring the assembly effect.

[0055] The application scenarios of the sealing ring assembly device provided in this embodiment include but are not limited to the assembly of the sealing ring 10 between the tube body 8 and the connector 9 in the breathing tube group, and can also be suitable for other pipes that need to be equipped with the sealing ring 10.

[0056] In one embodiment, the spreading mechanism 2 includes a supporting box 24, a driving structure 23 and an intermediate connecting rod structure 22 arranged in the supporting box 24, and the intermediate connecting rod structure 22 extends out of one side of the supporting box 24 and is connected to each supporting claw 21; a slide rail structure 6 is arranged between the supporting box 24 and the supporting body 1, and the linear driving mechanism 3 is arranged in the supporting body 1, and the linear driving mechanism 3 passes through the supporting body 1 through a connecting member 7 and is connected to the supporting box 24.

[0058] In this embodiment, by setting up the support box 24, the driving structure 23 and the intermediate connecting rod structure 22 can be set in the support box 24, which is not only beneficial to the protection of the driving structure 23 and the intermediate connecting rod structure 22, but also makes the overall sealing ring assembly equipment beautiful.

[0059] In this embodiment, the linear drive mechanism 3 is arranged in the support body 1, which is not only conducive to the protection of the linear drive mechanism 3, but also makes the sealing ring assembly device beautiful as a whole. It should be noted here that a avoidance hole for avoiding the connecting member 7 is arranged on the support body 1 to prevent the support body 1 from affecting the linear drive mechanism 3 to drive the support box 24 to move along the slide rail structure 6.

[0060] Exemplarily, the linear drive mechanism 3 may be a cylinder, a hydraulic cylinder or a linear motor, or may be a drive motor and a lead screw mechanism.

[0061] In one embodiment, the intermediate connecting rod structure 22 includes a first connecting plate 221, a first fixed block 222, a second connecting plate 223 and a second fixed block 224. The first fixed block 222 is fixed to the inner side of the support box 24. The number of the first connecting plates 221 and the number of the second connecting plates 223 are consistent with the number of the supporting claws 21. One end of the first connecting plate 221 extends out of the support box 24 and is connected to the corresponding supporting claw 21, and the other end of the first connecting plate 221 is rotatably connected to the corresponding second connecting plate 223. The first connecting plate 221 is distributed along the circumference of the first fixed block 222 and is rotatably connected to the first fixed block 222. The second connecting plate 223 is distributed along the circumference of the second fixed block 224 and is rotatably connected to the second fixed block 224. The second fixed block 224 is connected to the driving structure 23. The first connecting plate 221 is a bent plate. When the driving structure 23 is actuated, the first connecting plate 221 rotates with the rotation connection position with the first fixed block 222 as the rotation center to open or reset the supporting claw 21.

[0063] See also Figure 8The first connecting plate 221 is a bent plate, and one end of the first connecting plate 221 is fixedly connected to the corresponding supporting claw 21. For example, the first connecting plate 221 and the corresponding supporting claw 21 can be detachably connected by bolts or screws. The middle area of ​​the first connecting plate 221 is rotatably connected to the first fixing block 222, and one end of the first connecting plate 221 is rotatably connected to the corresponding second connecting plate 223.

[0064] See also Figure 8 When the driving structure 23 drives the second fixing block 224 to move to the right, the first connecting plate 221 rotates relative to the first fixing block 222, and the end of the first connecting plate 221 connected to the second connecting plate 223 moves toward the direction close to the central axis of the first fixing block 222, while the end of the first connecting plate 221 connected to the supporting claw 21 moves away from the central axis of the first fixing block 222. At this time, the supporting claw 21 gradually opens. Figure 8 When the driving structure 23 drives the second fixed block 224 to move to the left, the first connecting plate 221 rotates relative to the first fixed block 222, and the end of the first connecting plate 221 connected to the second connecting plate 223 moves in the direction away from the central axis of the first fixed block 222, while the end of the first connecting plate 221 connected to the supporting claw 21 moves in the direction close to the central axis of the first fixed block 222. At this time, the supporting claw 21 gradually closes.

[0065] The intermediate connecting rod structure 22 provided in this embodiment is not only simple in structure, but also can realize accurate control of the position of the supporting claw 21 .

[0066] Exemplarily, the rotational connection between the first connecting plate 221 and the first fixing block 222 , the first connecting plate 221 and the second connecting plate 223 , and the second connecting plate 223 and the second fixing block 224 is achieved by a shaft pin connection.

[0067] Preferably, the number of the supporting claws 21 is four. In this case, the number of the first connecting plates 221 and the number of the second connecting plates 223 are both four.

[0070] Exemplarily, the driving structure 23 may be directly fixed on the inner side of the supporting box 24; or, the driving structure 23 may be supported inside the supporting box 24 by a bracket or the like.

[0071] Regarding the shape of the supporting claw 21, in one embodiment, see Fig.10The support claw 21 is a plate-like structure, and the support claw 21 includes a tip portion 211, a bending connection portion 212 and a main body portion 213.
