During the production process of the infusion flow regulating valve, the adjusting roller 20 needs to be assembled into the installation cavity of the housing 10. Currently, the assembly of the infusion flow regulating valve generally adopts manual assembly or semi-automatic assembly, and the assembly efficiency is low. Therefore, further improvement is needed. Utility Model Content

[0004] In order to improve the assembly efficiency of the housing and the adjusting roller, this application provides an automatic assembly device for an infusion flow regulating valve.

[0005] The automatic assembly device for an infusion flow regulating valve provided by this application adopts the following technical solution:

[0006] An automatic assembly device for an infusion flow regulating valve includes a workbench, a housing transfer disk rotatably connected to the workbench, a roller transfer disk rotatably connected to the workbench and located on one side of the housing transfer disk, a housing feeding track provided on the workbench for feeding the housing transfer disk, a roller feeding track provided on the workbench for feeding the roller transfer disk, and a pushing disk rotatably connected to the workbench. The outer peripheral wall of the housing transfer disk has housing tooling grooves for the housing to slide and insert, and a plurality of housing tooling grooves are provided and are spaced apart around the axis of the housing transfer disk. The workbench is provided with a housing anti-detachment edge on the side of the housing transfer disk. The outer peripheral wall of the roller transfer disk has roller tooling grooves for the adjusting roller to be clamped, and a plurality of roller tooling grooves are provided and are spaced apart around the axis of the roller transfer disk. The workbench is provided with a roller anti-detachment edge on the side of the roller transfer disk. Both the housing anti-detachment edge and the roller anti-detachment edge are provided with assembly openings. The housing anti-detachment edge is provided with a pushing groove downstream of the assembly opening. The pushing disk is provided with a pushing rod that slides into the pushing groove and pushes the adjusting roller into the housing installation cavity.

[0007] By adopting the above technical solution, the housing is conveyed through the housing loading track and inserted into the housing tooling groove on the housing transfer disk. During the continuous rotation of the housing transfer disk, continuous feeding is carried out for each housing tooling groove. The adjusting roller is conveyed through the roller loading track and inserted into the roller tooling groove on the roller transfer disk. During the continuous rotation of the roller transfer disk, continuous feeding is carried out for each roller tooling groove. When the housing is transported along the housing anti-detachment edge and the adjusting roller is transported along the roller anti-detachment edge to the assembly port, the adjusting roller is directly opposite to the installation cavity opening of the housing. The roller transfer disk and the housing transfer disk continue to rotate. The adjusting roller disengages from the roller anti-detachment edge, and the adjusting roller slides into the installation cavity opening of the housing under the action of centrifugal force. And during the continuous rotation, the adjusting roller is clamped into the installation cavity opening of the housing under the guiding action of the inner side wall of the housing anti-detachment edge. Subsequently, when the housing with the adjusting roller is transported to the position of the pushing groove, the pushing disk rotates to drive the push rod to rotate, and the push rod slides into the installation cavity opening of the housing to hard-push the adjusting roller into the installation cavity of the housing, completing the automatic assembly of the adjusting roller and the housing, and improving the assembly efficiency of the housing and the adjusting roller.

[0008] Preferably, the housing tooling groove extends to the upper and lower end faces of the housing transfer disk. The workbench is provided with a housing supporting plate located below the housing transfer disk. The housing supporting plate is provided with a material dropping opening through which the assembled housing can fall, and the workbench is provided with a collection box for collecting the housing.

[0009] By adopting the above technical solution, a housing supporting plate is provided to support the housing. After the push rod hard-pushes the adjusting roller into the installation cavity of the housing, the housing transfer disk transports the assembled housing. After transporting to the position of the material dropping opening, the housing naturally falls after losing the support of the housing supporting plate and drops into the collection box for centralized collection. The empty housing transfer disk continues to rotate to the outlet of the housing loading track to be reloaded, and so on, for automatic continuous assembly.

[0010] Preferably, the housing anti-detachment edge is fixedly connected to the housing supporting plate.

[0011] Preferably, the push rod is slidably connected to the upper end face of the pushing disk along the radial direction of the pushing disk, and the pushing disk is provided with an adjusting member for adjusting the sliding position of the push rod.

[0012] By adopting the above technical solution, the sliding position of the push rod is adjusted through the adjusting member, so as to adjust the length of the push rod extending into the installation cavity opening of the housing, and thus adjust the pushing depth of the push rod.

[0013] Preferably, the push rod is provided with an adjusting groove along the radial direction, the pushing disk is provided with a threaded hole, the adjusting member is an adjusting bolt passing through the adjusting groove, the adjusting bolt is threadedly connected to the threaded hole, and the nut end face of the adjusting bolt abuts against the upper end face of the push rod.

[0014] By adopting the above technical solution, when it is necessary to adjust the sliding position of the push rod, loosen the adjusting bolt. After releasing the fixation of the push rod, the position of the push rod can be adjusted by sliding. After the adjustment is completed, tighten the adjusting bolt again so that the end face of the nut of the adjusting bolt abuts against the upper end face of the push rod to limit the sliding of the push rod in a damping manner.

[0015] Preferably, a chute is radially formed on the upper end face of the propulsion disc, and a slider slidably connected to the chute is fixedly connected to the push rod.

[0016] By adopting the above technical solution, through the arrangement of the chute and the slider, a sliding assembly of the push rod and the propulsion disc is realized.

[0017] Preferably, the adjusting member includes a mounting screw coaxially and fixedly connected to the upper end face of the propulsion disc, a sliding sleeve slidably sleeved on the mounting screw along the axial direction, a hinge rod with one end hinged to the sliding sleeve and the other end hinged to the push rod, and a nut sleeve rotatably connected to the sliding sleeve and threadedly sleeved on the mounting screw.

[0018] By adopting the above technical solution, when it is necessary to adjust the sliding of the push rod, rotate the nut sleeve. Under the restriction of the thread of the mounting screw, the nut sleeve drives the sliding sleeve to lift and slide along the axial direction of the mounting screw, so as to drive the push rod to slide along the radial direction of the propulsion disc through the hinge rod.

[0019] Preferably, a knob is coaxially and fixedly sleeved on the nut sleeve.

[0020] By adopting the above technical solution, the addition of the knob facilitates the rotation of the nut sleeve.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. The housing is conveyed and inserted into the housing tooling groove on the housing transfer disc through the housing loading track. During the continuous rotation of the housing transfer disc, continuous feeding is carried out for each housing tooling groove. The adjusting roller is conveyed and inserted into the roller tooling groove on the roller transfer disc through the roller loading track. During the continuous rotation of the roller transfer disc, continuous feeding is carried out for each roller tooling groove. When the housing moves along the housing anti-detachment edge and the adjusting roller moves along the roller anti-detachment edge to the assembly port, the adjusting roller is aligned with the installation cavity opening of the housing. The roller transfer disc and the housing transfer disc continue to rotate. The adjusting roller disengages from the roller anti-detachment edge. Under the action of centrifugal force, the adjusting roller slides into the installation cavity opening of the housing. And during the continuous rotation, under the guiding action of the inner side wall of the housing anti-detachment edge, the adjusting roller is clamped into the installation cavity opening of the housing. Subsequently, when the housing with the adjusting roller is transferred to the position of the push groove, the propulsion disc rotates to drive the push rod to rotate, and the push rod slides into the housing installation cavity opening to hard-press the adjusting roller into the installation cavity of the housing, completing the automatic assembly of the adjusting roller and the housing, and improving the assembly efficiency of the housing and the adjusting roller;

[0023] 2. Adjust the sliding position of the push rod through the adjusting member, so as to adjust the length of the push rod extending into the mounting cavity opening of the housing, and thus adjust the pushing depth of the push rod. BRIEF DESCRIPTION OF THE DRAWINGS

The housing support plate 23 is provided with a blanking opening 231 through which the assembled housing 10 drops. A collection box 7 for collecting the housing 10 is provided on the upper end surface of the workbench 1.

[0036] Refer to Figure 1 , Figure 3 , the housing support plate 23 is fixedly connected with a housing anti - detachment edge 24 located on the side of the housing transfer disk 2. The outer peripheral wall of the roller transfer disk 4 has a roller tooling groove 42 for the adjusting roller 20 to be clamped. The roller tooling groove 42 extends to the upper and lower end surfaces of the roller transfer disk 4. A plurality of roller tooling grooves 42 are provided and are spaced apart around the axis of the roller transfer disk 4. The support rods 14 are fixedly connected with a roller support plate 43 located below the roller transfer disk 4.

Assembly openings 241 for the adjusting roller 20 to slide into the installation cavity of the housing 10 are provided in both the housing anti - detachment edge 24 and the roller anti - detachment edge 44.

[0037] Refer to Figure 3 ,Figure 4 , a shell anti - detachment rib 24 is provided with a pushing groove 242 downstream of the assembly port 241, and the length direction of the pushing groove 242 extends around the circumferential direction of the shell transfer disk 2.

[0038] The implementation principle of an automatic assembly device for an infusion flow regulating valve in an embodiment of the present application is as follows: When the shell tooling groove 22 on the shell transfer disk 2 corresponds to the discharge port of the shell feeding track 3, the shell 10 in the shell feeding track 3 is transported and inserted into the shell tooling groove 22 on the shell transfer disk 2. During the continuous rotation of the shell transfer disk 2, continuous feeding is performed for each shell tooling groove 22. When the roller tooling groove 42 on the roller transfer disk 4 corresponds to the discharge port of the roller feeding track 5, the adjusting roller 20 in the roller feeding track 5 is transported and inserted into the roller tooling groove 42 on the roller transfer disk 4. During the continuous rotation of the roller transfer disk 4, continuous feeding is performed for each roller tooling groove 42;

[0039] When the shell 10 is transported along the shell anti - detachment rib 24 and the adjusting roller 20 is transported along the roller anti - detachment rib 44 to the assembly port 241, the adjusting roller 20 is directly opposite to the installation cavity opening of the shell 10. The roller transfer disk 4 and the shell transfer disk 2 continue to rotate. The adjusting roller 20 is separated from the roller anti - detachment rib 44, and the adjusting roller 20 slides into the installation cavity opening of the shell 10 under the action of centrifugal force. And during the continuous rotation, the adjusting roller 20 is stuck into the installation cavity opening of the shell 10 under the guiding action of the inner side wall of the shell anti - detachment rib 24. Subsequently, when the shell 10 equipped with the adjusting roller 20 is transported to the position of the pushing groove 242, the pushing disk 6 rotates to drive the push rod 62 to rotate, so that the push rod 62 slides into the installation cavity opening of the shell 10 during rotation to hard - push the adjusting roller 20 into the installation cavity of the shell 10. The shell transfer disk 2 transports the assembled shell 10. After being transported to the position of the blanking port 231, the shell 10 loses the support of the shell support plate 23 and naturally falls, dropping into the collection box 7 for centralized collection. The empty shell transfer disk 2 continues to rotate to the outlet of the shell feeding track 3 to be re - loaded. Repeating this process realizes automatic continuous assembly and improves the assembly efficiency of the shell 10 and the adjusting roller 20.

[0040] Embodiment 2:

[0041] The difference from Embodiment 1 is that with reference to Figure 5 , a chute is radially formed on the upper end surface of the pushing disc 6. The chute is a dovetail groove. The ejector rod 62 is fixedly connected with a slider slidably connected to the chute, and the slider is a dovetail block. The adjusting member 8 includes a mounting screw 81 coaxially and fixedly connected to the upper end surface of the pushing disc 6, a sliding sleeve 82 slidably sleeved on the mounting screw 81 along the axial direction, a hinged rod 83 with one end hinged to the sliding sleeve 82 and the other end hinged to the ejector rod 62, and a screw sleeve 84 rotatably connected to the sliding sleeve 82 and threadedly sleeved on the mounting screw 81. A knob 85 is coaxially and fixedly sleeved on the screw sleeve 84.

[0042] When the ejector rod 62 needs to be slidably adjusted, rotate the knob 85 to drive the screw sleeve 84 to rotate. Under the restriction of the thread of the mounting screw 81, the screw sleeve 84 drives the sliding sleeve 82 to perform lifting and sliding along the axial direction of the mounting screw 81, so as to drive the ejector rod 62 to slide along the radial direction of the pushing disc 6 through the hinged rod 83.

[0043] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
