[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restricts the present utility model and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0031] Such as Figures 1 to 3As shown in the figure, an embodiment of the present utility model provides an infusion set rotating material taking device. The infusion set rotating material taking device is used to receive the infusion set at the discharging end of the hanging material transportation mechanism and adjust the posture of the infusion set. The infusion set rotating material taking device includes a fixed seat 100, a rotating shaft 200, a mounting member 300 and a supporting member 400. Among them, the rotating shaft 200 is arranged on the fixed seat 100. The mounting member 300 has a connecting end and a mounting end arranged oppositely. The connecting end is connected to the rotating shaft 200. A plurality of first clamping portions 310 are arranged at intervals along the extending direction of the rotating shaft 200 at the mounting end. The first clamping portions 310 are used for clamping the infusion set. The supporting member 400 is arranged on the mounting member 300. The supporting member 400 has a plurality of supporting grooves 401 arranged at intervals along the extending direction of the rotating shaft 200. The plurality of supporting grooves 401 are arranged in one-to-one correspondence with the plurality of first clamping portions 310. The first supporting groove 401 extends along the direction from the first clamping portion 310 to the rotating shaft 200. When the rotating shaft 200 rotates, the supporting groove 401 can support the corresponding infusion set.

[0032] Applying the technical solution of the present utility model, a plurality of first clamping portions 310 can clamp the infusion set from the hanging material transporting device. At this time, the infusion set is in a vertical state under the action of gravity. After the first clamping portion 310 clamps and fixes the infusion set, the rotating shaft 200 is rotated towards the side of the mounting member 300 away from the infusion set, and the infusion set can be converted into a horizontal state under the support of the supporting member 400 to complete the adjustment of the posture of the infusion set. During the rotation of the mounting member 300, the infusion set can enter the corresponding supporting groove 401 under the action of gravity. The supporting member 400 can isolate adjacent infusion sets through a plurality of supporting grooves 401, preventing adjacent or more infusion sets from being entangled during the rotation of the rotating shaft 200, ensuring the stability of the posture during the adjustment of the posture of the infusion set, providing a good positioning basis for subsequent processes such as winding or packaging of the infusion set, and ensuring the normal production of the infusion set in subsequent assembly, winding or packaging processes, improving the production quality and production efficiency of the infusion set.

[0033] Specifically, the infusion set rotating material taking device has a vertically set state and a horizontally set state arranged oppositely. When the infusion set rotating material taking device is in the vertical state, as Figure 2 and Figure 3 shown, at this time the mounting member 300 is vertically arranged, the first clamping portion 310 clamps the infusion set, and the infusion set will naturally hang down under the action of gravity. When the infusion set rotating material taking device is in the horizontal state, as Figure 1 shown, the mounting member 300 is horizontally arranged, and the infusion set will be kept horizontal under the support of the supporting member 400. The mounting member 300 rotates relative to the fixed seat 100 through the rotating shaft 200, enabling the infusion set rotating material taking device to switch between the vertical state and the horizontal state. When the mounting member 300 rotates around the rotating shaft 200 towards the side away from the infusion set, it is switched from the vertical state to the horizontal state.

[0034] Further, a guiding structure is provided on the supporting member 400, and the guiding structure is used to guide the movement of the infusion set in the supporting groove 401. Through the above arrangement, providing the guiding structure on the supporting member 400 can guide the infusion set during the process of the infusion set rotating and picking device switching from the vertical state to the horizontal state, enabling the infusion set to move towards the bottom of the supporting groove 401, preventing two adjacent infusion sets from entering the same supporting groove 401, and ensuring that each infusion set can enter the corresponding supporting groove 401 to improve the separation effect on the infusion sets.

[0035] Specifically, the width of the supporting groove 401 gradually increases from the bottom of the supporting groove 401 to the notch direction of the supporting groove 401, and the side wall of the supporting groove 401 forms a guiding structure. Through the above arrangement, when the infusion set is not corresponding to the bottom of the supporting groove 401, as the supporting member 400 rotates, the infusion set can slide through the side wall of the supporting groove 401 to slide towards the bottom of the supporting groove 401, so that the infusion set can stably enter the supporting groove 401.

[0036] In some embodiments of the present application, the supporting member 400 has a top plate 410 and a bottom plate 420 arranged oppositely. The bottom plate 420 is used to connect with the mounting member 300. The top plate 410 has a plurality of supporting grooves 401 arranged in sequence along the extending direction of the rotating shaft 200. A strengthening structure is provided between the top plate 410 and the bottom plate 420 to support the top plate 410. Through the above arrangement, the strengthening structure can support the top plate 410 to prevent the top plate 410 from sagging, so as to ensure that the bottom of the supporting groove 401 can be on the same plane, enabling multiple infusion sets to be on the same horizontal plane after being placed on the supporting member 400, which is convenient for the subsequent positioning of the assembly process or winding process of the infusion set, etc.; and, the strengthening structure can also prevent the top plate 410 from shifting, ensuring that the first clamping portion 310 can be aligned with the corresponding supporting groove 401 to ensure the supporting effect of the supporting member 400.

[0037] In a specific embodiment of the present application, the top plate 410 has a plurality of folding plates 411 arranged in sequence along the extending direction of the rotating shaft 200. The folding plates 411 have supporting grooves 401, and a strengthening structure is provided between every two adjacent folding plates 411. Through the above arrangement, the folding structure of the folding plates 411 can form the supporting grooves 401 by the folding plates 411 themselves without the need for additional grooving, simplifying the structure of the supporting member 400.

[0038] Optionally, along the extending direction of the folding plate 411, the cross-sectional shape of the folding plate 411 can be V-shaped, that is, the folding plate 411 is formed by connecting two plate-like structures with an included angle.

[0039] Optionally, along the extending direction of the folding plate 411, the cross-sectional shape of the folding plate 411 can be U-shaped, that is, the folding plate 411 is formed by connecting two arc-shaped plate structures with an included angle.

[0040] Specifically, the reinforcing structure can be in the structure of a rib plate or a support column.

[0041] Furthermore, the reinforcing structure can also be arranged corresponding to the bottom of the supporting groove 401.

In the traditional technical solution, only one clamping mechanism is provided. After the infusion set is clamped by the clamping mechanism, there is still a free end that swings, and the phenomenon of the infusion sets being wound around each other will occur. In the present application, by arranging the second clamping portions 320 at each corresponding supporting groove 401, the second clamping portions 320 can cooperate with the first clamping portions 310 to jointly clamp the infusion set, so that the infusion set can have two fixed points on the mounting member 300, so as to further improve the stability of the infusion set during the posture adjustment process.

[0044] In a specific embodiment of the present application, the second clamping portions 320 and the first clamping portions 310 are oppositely arranged at both ends of the mounting member 300 to increase the distance between the second clamping portions 320 and the first clamping portions 310, and reduce the length of the freely swingable part of the infusion set, so as to ensure the stability of the infusion set in the supporting groove 401.

[0045] In another specific embodiment of the present application, a mounting groove 402 is arranged on the supporting member 400. The mounting groove 402 extends along the extending direction of the rotating shaft 200. The second clamping portions 320 are arranged in the mounting groove 402. In the depth direction of the supporting groove 401, the clamping ends of the second clamping portions 320 protrude from the bottom of the supporting groove 401. Through the above arrangement, the second clamping portions 320 can cooperate with the first clamping portions 310 to stably fix the infusion set in the supporting groove 401, and prevent the adjacent two infusion sets from moving in the adjacent two supporting grooves 401, so as to further ensure the stability of the infusion set fixed in the supporting groove 401.

[0046] Specifically, an integral clamping mechanism can be provided on the mounting member 300.

[0050] Specifically, the number of the mounting plates 330 can also be one, that is, a plurality of first clamping portions 310 and the supporting member 400 are fixed by one mounting plate 330.

[0051] In the present application, a cut surface structure can be provided on the side wall of the rotating shaft 200 to facilitate the connection and fixation of the mounting plate 330 and the rotating shaft 200.
