[0026] The first linear guide rail 1 is used to convey the inner sealing ring 3, and the second linear guide rail 2 is used to convey the bottle cap 4;

[0027] When the first linear guide 1 transfers the inner sealing ring 3 to the first positioning member 5, the lifting cylinder 8 lifts the inner sealing ring 3, and the servo motor 9 drives the rotating assembly 10 to drive the material transfer tube 11 to rotate onto the inner sealing ring 3. After the material transfer tube 11 absorbs the inner sealing ring 3, the servo motor 9 drives the rotating assembly 10 to drive the material transfer tube 11 to rotate onto the bottle cap 4 fixed by the second positioning member 6, and the material transfer tube 11 then places the inner sealing ring 3 into the bottle cap 4 by blowing.

[0028] Specifically, in the present embodiment, the first linear guide 1 and the second linear guide 2 are provided to respectively convey the inner sealing ring 3 and the bottle cap 4, and when the inner sealing ring 3 and the bottle cap 4 are respectively conveyed to the first positioning member 5 and the second positioning member 6 for fixing and positioning, the inner sealing ring 3 is lifted up by the lifting cylinder 8, and then the rotating assembly 10 is driven by the servo motor 9 to drive the material transfer tube 11 to suck the inner sealing ring 3 to the top of the corresponding bottle cap 4, and finally, the inner sealing ring 3 is blown to the corresponding position inside the bottle cap 4 through the material transfer tube 11, and the inner sealing ring 3 is accurately placed in the bottle cap 4, so that the assembly of the inner sealing ring 3 and the bottle cap 4 can be completed conveniently and quickly, which can effectively avoid assembly failures, improve assembly efficiency and ensure assembly effect.

[0029] In an optional embodiment, if Figure 2 As shown, an air hole 111 is provided at the end of the material transfer tube 11. The air hole 111 generates negative pressure by suction to absorb the inner sealing ring 3. When it is aligned with the bottle cap 4, the suction of the inner sealing ring 3 is stopped, and the inner sealing ring 3 is placed in the bottle cap 4 by blowing.

[0030] Specifically, an air hole 111 is provided at the end of the material transfer tube 11, and the rotating assembly 10 drives the material transfer tube 11 to make its end close to the inner sealing ring 3, and then air is sucked through the air hole 111 to generate negative pressure to suck the inner sealing ring 3, and then the rotating assembly 10 drives the inner sealing ring 3 to approach and align it with the bottle cap 4 from top to bottom. After aligning with the bottle cap 4, the air hole 111 changes the air suction to blowing, so that the inner sealing ring 3 is blown to adhere to the corresponding position of the bottle cap 4, thereby completing the assembly of the inner sealing ring 3 appropriately. Among them, the method of being able to suck and blow air at the air hole 111 can be achieved by arranging an air pump or other structure inside the material transfer tube 11.

[0031] In an optional embodiment, if Figure 3 As shown, the first positioning member 5 is a positioning block provided with a positioning groove, and the second positioning member 6 is a positioning plate, and the side wall of the positioning plate can be embedded with the side wall of the bottle cap 4.

[0032] Specifically, the positioning groove in the first positioning member 5 includes two interconnected through grooves, and a protruding block for carrying the inner sealing ring 3 is provided between the two through grooves. The inner sealing ring 3 is first transferred to the protruding block by the first linear guide rail 1, and then ejected by the ejection cylinder located below the positioning groove. The second positioning member 6 can be a fixed plate 15, and the second linear guide rail 2 transfers the bottle cap 4 along the groove 71 provided on the push plate 7. When the bottle cap 4 is transferred to the side of the fixed plate 15, the fixed plate 15 will be driven to approach the bottle cap 4, and then fit and squeeze the side wall of the bottle cap 4 from the side to fix and position the bottle cap 4, wherein the fixed plate 15 is provided with multiple structures that can fit with the side walls of multiple bottle caps 4 at the same time, so as to fix multiple bottle caps 4 at the same time.

[0033] In an optional embodiment, if Figure 1 As shown, it includes a discharging horizontal cylinder 12 and a push plate 7. The discharging horizontal cylinder 12 is connected to the push plate 7. After the inner sealing ring 3 is placed in the bottle cap 4, the positioning plate is away from the bottle cap 4 to release the fixation of the bottle cap 4. After the second linear guide rail 2 continues to transport the bottle cap 4 equipped with the inner sealing ring 3 to the groove 71 provided on the push plate 7, the discharging horizontal cylinder 12 drives the push plate 7 to move, thereby driving the bottle cap 4 and the inner sealing ring 3 to move to realize the discharging operation.

[0034] Specifically, in the present embodiment, after the inner sealing ring 3 is placed in the bottle cap 4 and the assembly is completed, the positioning plate moves away from the bottle cap 4, thereby releasing the fixation of the bottle cap 4, and the second linear guide rail 2 continues to transport the bottle cap 4 equipped with the inner sealing ring 3 to the groove 71 of the push plate 7, and then the push plate 7 is driven to move by the discharging horizontal cylinder 12, thereby driving the bottle cap 4 and the inner sealing ring 3 to move to realize the discharging operation.

[0035] In an optional embodiment, if Figure 1 , 3 As shown in FIG. 4 , the lifting cylinder 8 is connected to the push rod 14 through the fixing part 13. The lifting cylinder 8 can drive the push rod 14 to push up, so that the push rod 14 passes through the positioning groove, and the push rod 14 carries the inner sealing ring 3 located on the positioning groove upward through the tapered centering 141 set at its end.

[0036] Specifically, a fixing part 13 is arranged above the jacking, and a corresponding mounting groove is provided on the fixing part 13 to fix the push rod 14. When the inner sealing ring 3 reaches the positioning groove of the first positioning part 5, the lifting cylinder 8 drives the push rod 14 to push up. The push rod 14 is provided with a tapered centering 141 at the upper end portion. The inner sealing ring 3 can be fitted outside the tapered centering 141 through the tapered centering 141, so as to facilitate the inner sealing ring 3 to be stably carried through the positioning groove and rise to the position abutting against the material transfer tube 11.

[0037] In an optional embodiment, if Figure 1As shown, it includes a fixing plate 15 , which is connected to the rotating assembly 10 . The fixing plate 15 is provided with a plurality of fixing holes 151 , and the fixing holes 151 are used to fix the material transfer tube 11 .

[0038] Specifically, by providing a fixed plate 15 connected to the rotating component 10, and providing a fixing hole 151 in the fixed plate 15, the material transfer tube 11 is fixedly connected to the rotating component 10. At the same time, by providing multiple fixing holes 151 in the fixed plate 15, it is convenient to assemble multiple material transfer tubes 11 at the same time, so that the inner sealing ring 3 can be assembled into the bottle cap 4 through the multiple material transfer tubes 11 at the same time, which is conducive to further improving the assembly efficiency.

[0039] Furthermore, if Figure 1 As shown, the rotating assembly 10 includes a rotating arm 101 and a connecting rod 102 which are transmission-connected. The connecting rod 102 is connected to the fixed plate 15. The servo motor 9 drives the rotating arm 101 to drive the connecting rod 102 to rotate, thereby driving the material transfer tube 11 in the fixed plate 15 to rotate onto the inner sealing ring 3. After the material transfer tube 11 absorbs the inner sealing ring 3, the servo motor 9 drives the rotating arm 101 to drive the connecting rod 102 to rotate, thereby driving the material transfer tube 11 and the inner sealing ring 3 to rotate onto the bottle cap 4 fixed by the second positioning member 6, and the material transfer tube 11 then places the inner sealing ring 3 into the bottle cap 4.

[0040] Specifically, in this embodiment, the rotating assembly 10 is configured to include a rotating arm 101 and a connecting rod 102, and the connecting rod 102 is connected to the fixed plate 15, so that the fixed plate 15 and the material transfer tube 11 can be rotated by the rotating arm 101 and the connecting rod 102. Among them, two rotating arms 101 can be provided, and they are connected to the upper and lower ends of the connecting rod 102 through bearings, and the fixed plate 15 is fixedly connected to the middle of the connecting rod 102, which is conducive to more stable rotation of the material transfer tube 11, thereby ensuring the stable and smooth suction and assembly of the inner sealing ring 3.

[0041] In an optional embodiment, a first positioning sensor 16 is provided in the first positioning member 5, and a second positioning sensor 17 is provided in the second positioning member 6. The first positioning sensor 16 is used to detect whether the inner sealing ring 3 is in place, and the second positioning sensor 17 is used to detect whether the bottle cap 4 is in place.

[0042] Specifically, by respectively arranging the first positioning member 5 and the second positioning member 6 with the first positioning sensor 16 and the second positioning sensor 17, it is helpful to ensure that the inner sealing ring 3 and the bottle cap 4 both reach the corresponding positions, so as to ensure that the subsequent sucking of the inner sealing ring 3 and the blowing of the inner sealing ring 3 to assemble it into the bottle cap 4 can be carried out accurately. Therefore, this embodiment is helpful to further ensure the accurate and smooth assembly of the inner sealing ring 3. Among them, in other embodiments, such as Figure 1As shown, the second positioning sensor 17 is arranged in the push plate 7 . Since the push plate 7 faces the bottle cap 4 , the second positioning sensor 17 can also have the corresponding effect of being arranged in the second positioning member 6 .

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
