It is widely used in medical devices such as syringes, infusion sets, and catheters, providing a convenient and reliable connection solution for the transmission of liquid and gaseous medical fluids.

[0003] The Luer connector includes a female head and a male head that is inserted into the female head, and the male head and the female head are usually assembled using an assembly device; the existing assembly device includes a frame, a first jaw chuck and a second jaw chuck that are slidably mounted on the frame, and a cylinder is provided between the second jaw chuck and the frame; the specific use steps are as follows: use the first jaw chuck to hold the female head so that the female head is in a vertical state; then slide the position of the second jaw chuck to pick up the male head, and adjust the position of the second jaw chuck so that the male head and the female head are in a facing state; then drive the cylinder to move the male head towards the side of the female head, thereby completing the assembly of the male head and the female head.

[0004] However, since it is necessary to use the first jaw chuck and the second jaw chuck to hold the male head and the female head one by one and adjust their positions to enable the precise assembly of the male head and the female head, this method has a low production efficiency. Therefore, an assembly device for the efficient and precise automatic splicing of Luer male and female connectors is needed. Summary of the Utility Model

During the rotation of the installation disk 4, the transfer track 11 can place the male connectors into the first installation grooves 42 one by one. In other embodiments, a rubber layer is provided on the inner wall of the first installation groove 42, which can enable the male connector to be in flexible contact with the inner wall of the first installation groove 42, reducing the damage of the male connector during the assembly process.

[0036] Referring to Figure 2 and Figure 3 , a movable hole 43 is formed at the bottom of the installation groove 41, one end of the movable hole 43 communicates with the bottom of the installation disk 4, and all the movable holes 43 correspond to the respective first installation grooves 42 one by one; a movable component 7 is installed on the installation disk 4, and the movable component 7 includes a movable seat 71 and a reset member 72. The movable seat 71 is installed in the installation groove 41, and a second installation groove 711 is formed on the side of the movable seat 71 close to the first installation groove 42, and the side wall of the second installation groove 711 communicates with the side wall of the movable seat 71; the other transfer track 11 is arranged opposite to the second installation groove 711 for placing the female connectors into the second installation grooves 711 one by one.

[0037] The reset member 72 includes a telescopic rod 721, a first spring 722, a limiting plate 723 and a transfer roller 724. There are two groups of telescopic rods 721 and springs. One end of the two groups of telescopic rods 721 is connected to the movable seat 71, and the other ends of the two groups of telescopic rods 721 pass through the movable holes 43 and are fixed to the limiting plate 723; the first spring 722 is sleeved on the outer wall of the telescopic rod 721, and the two ends of the first spring 722 are respectively fixed to the limiting plate 723 and the bottom wall of the installation disk 4. The elastic force of the first spring 722 is used to drive the limiting plate 723 to move away from the installation disk 4.

[0038] Referring to Figure 3 , an extension part 44 is integrally formed on the bottom of the installation disk 4, a sliding groove 45 is formed in the extension part 44, and the extending direction of the sliding groove 45 is the same as the extending direction of the movable hole 43; a sliding block 725 is arranged on one side of the transfer roller 724, and the sliding block 725 is slidably installed in the sliding groove 45; the limiting plate 723 abuts against the transfer roller 724 under the elastic force of the first spring 722.

[0039] A sliding seat 51 is arranged on the side wall of the frame 3, and the sliding seat 51 is annularly arranged; the transfer roller 724 abuts against the upper wall of the sliding seat 51 under the elastic force of the first spring 722, which can increase the smoothness of the rotation of the installation seat on the frame 3; the guiding seat 5 is installed on the upper surface of the sliding seat 51, and the distance between the upper surface of the guiding seat 5 and the sliding seat 51 decreases from the middle of the guiding seat 5 to both ends of the guiding seat 5.

[0041] The implementation principle of a spiral joint assembly device in an embodiment of the present application is as follows:

[0042] The two conveying structures respectively and precisely convey the male head and the female head into the first installation groove 42 of the installation disk 4 and the second installation groove 711 of the movable seat 71; at this time, the driving motor rotates the installation disk 4, and when the conveying roller 724 contacts one side of the guiding seat 5 and enters the upper surface of the guiding seat 5, the movable seat 71 moves towards the side of the first installation groove 42; when the conveying roller 724 contacts the middle of the guiding seat 5, the distance between the movable seat 71 and the upper wall of the installation groove 41 reaches the minimum, that is, the automatic assembly of the male head and the female head is carried out at this time.

[0043] Since the conveying roller 724 is normally abutted against the upper surface of the sliding seat 51 under the elasticity of the first spring 722, when the conveying roller 724 moves from the middle of the guiding seat 5 towards the other side of the guiding seat 5, the movable seat 71 moves towards the side away from the first installation groove 42; the assembled male head and female head are kept in the first installation groove 42 and dropped into the blanking chute 61 under the guidance of the baffle 62; thus, the first installation groove 42 and the second installation groove 711 can be emptied, and the male head and the female head can be placed again, repeating this action can complete the automatic assembly of the male head and the female head, reduce the situation of frequently adjusting the position between the male head and the female head, and improve the assembly efficiency of the Luer male and female connectors.
