Therefore, the requirements for the degree of automation of infusion set packaging are increasing. Medical infusion sets are flexible, linear objects, and they need to be picked up, wound, and transported after winding before packaging.

[0003] At present, in order to realize the automatic winding of disposable infusion sets, the existing automatic winding devices for infusion sets all have a feeding device, and are provided with two feeding mechanisms that can approach each other, one of which grabs the front end of the infusion set and feeds it into the winding device for the infusion set. The other feeding mechanism grabs the rear end of the infusion set, and as the infusion set is wound, it gradually approaches the previous feeding mechanism, so as to ensure that the infusion set is straight and flat, and to ensure the effect and efficiency of the winding of the infusion set.

[0004] However, due to the influence of the infusion set winding speed, the winding uniformity of the infusion set, and the tightness of each coil, the existing infusion set feeding device causes the infusion set to be unevenly stressed and bent during the winding process, resulting in the infusion set being separated from the winding device or being entangled with other mechanisms during the winding process, thereby causing damage or unqualified winding.

[0046] like Figures 1 to 4As shown, the embodiment of the utility model provides an infusion device 300 feeding device including a head material taking platform 100, a tail material taking platform 200 and a transfer mechanism; a plurality of infusion devices 300 are arranged in a plurality of placement slots in a carrier in a horizontal direction, and the transfer mechanism is respectively connected to the head material taking platform 100 and the tail material taking platform 200, and the transfer mechanism can drive the tail material taking platform 200 to approach or move away from the head material taking platform 100 along a direction perpendicular to the extension of the placement slot, and the head material taking platform 100 is provided with a head material taking claw 110, and the head material taking claw 110 is arranged on the head material taking platform 100.

The tail clamping claw 212 is movably arranged on the tensioning portion 213 along the extension direction of the infusion set 300.

[0047] That is, the present invention provides an infusion pump 300 feeding device of an embodiment, by arranging a tensioning portion 213 on the tail material picking platform 200, and adjusting the distance between the tail clamping claw 212 and the fixing portion 211 by the tensioning portion 213, thereby adjusting the traction force of the tail clamping claw 212 on the infusion pump 300. As the head material picking platform 100 and the tail material picking platform 200 approach each other, the device adapts to the changes in the winding speed and the winding uniformity of the infusion pump 300, ensures that the infusion pump 300 is subjected to uniform force, solves the technical problem in the prior art that the infusion pump 300 is subjected to uneven force during the winding process, resulting in damage to the infusion pump 300 or unqualified winding, and improves the winding yield of the infusion pump 300.

[0048] Specifically, the placement slot is arranged on the carrier in the horizontal direction, and a plurality of placement slots are arranged on the carrier in parallel at intervals. In the present embodiment, the placement slot is in the shape of an elongated strip, and four placement slots are arranged on each carrier in the reverse direction perpendicular to the placement slot. The processed infusion set 300 is arranged in the placement slot in the carrier. The transfer mechanism is arranged as a horizontal conveying platform, and the tail material taking platform 200 is fixed on the sliding part of the horizontal conveying platform by bolts so that it can drive the tail material taking platform 200 to move, and the movement direction of the tail material taking platform 200 is consistent with the winding direction of the infusion set 300, that is, the tail material taking platform 200 can gradually approach the head material taking platform 100 when the infusion set 300 is wound. One end of the infusion set 300 is clamped on the head material taking platform 100 by the head material taking claw 110, and extends into the winding device for winding. The other end of the infusion set 300 is arranged on the tail material taking platform 200 by the material taking component 210. The fixing part 211 is connected to the tail material taking platform 200 by bolts and other connecting parts. The tensioning part 213 is installed on the fixing part 211. The tensioning part 213 can be provided with a tensioning spring, a winding drum or an electric push rod, etc., which are connected to the tail material taking claw, and gradually adjust the traction force on the tail material taking claw as the tail material taking platform 200 moves.

[0049] Furthermore, the tensioning part 213 includes a slide plate 2131, a guide rod 2132 and an elastic member 2133. The slide plate 2131 is slidably connected to the fixed part 211. The guide rod 2132 is arranged parallel to the top of the fixed part 211. One end of the elastic member 2133 is connected to the slide plate 2131, and the tensioning spring is sleeved on the guide rod 2132. The other end of the elastic member 2133 is connected to the fixed part 211, and the tail clamping claw 212 is fixed to the slide plate 2131.

[0050] Specifically, the slide plate 2131 can be slidably connected to the fixed part 211 through a slide rail slider, a guide rod and a linear bearing seat, or a guide groove slider. In this embodiment, the slide plate 2131 is slidably connected to the fixed part 211 through a sliding track and a slider, and the sliding track is arranged along the extension direction of the fixed part 211. One end of the guide rod 2132 is fixed to the fixed part 211 and is arranged parallel to the sliding track, and the guide rod 2132 is arranged just above the sliding track. The elastic member 2133 is specifically arranged as a spring, which is sleeved on the guide rod 2132, one end of which abuts against the fixed part 211, and the other end is connected to the slide plate 2131. When the slide plate 2131 moves along the sliding track, the guide block will move accordingly, and then according to the distance moved by the slide plate 2131, the spring is compressed to obtain the tensioning force. Therefore, by pushing the slide plate 2131 by the elastic member 2133, the tensioning force can be kept stable while the infusion set 300 is wound.

[0051] Furthermore, a plurality of head picking claws 110 are evenly arranged on the head picking platform 100 perpendicular to the extension direction of the carrier, and a plurality of picking components 210 are evenly arranged on the tail picking platform 200 along the arrangement direction of the head picking claws 110 , and the picking components 210 and the head picking claws 110 are arranged one by one.

[0052] Specifically, in this embodiment, four head material taking claws 110 are provided on the head material taking platform 100 and are installed in parallel on the head material taking platform 100. Correspondingly, four material taking components 210 corresponding to the head material taking claws 110 are provided on the tail material taking platform 200. That is, the head material taking claws 110 and the material taking components 210 are provided in pairs, so that multiple groups of infusion sets 300 can be grabbed and wound at the same time, thereby maintaining the winding efficiency of the infusion sets 300.

[0053] Furthermore, the tail clamping claw 212 includes a first driving member 2121 and a clamping arm 2122. The first driving member 2121 is connected to the slide plate 2131. The driving ends of the first driving member 2121 are respectively connected to the two clamping arms 2122 to drive the two clamping arms 2122 to move closer to or away from each other along a direction perpendicular to the extension direction of the placement groove.

[0054] Specifically, the first driving member 2121 is configured as a clamping cylinder, which is fixed to the connecting bracket by bolts. The two clamping arms 2122 are respectively connected to the two output ends of the clamping cylinder, so that the clamping cylinder can drive the two clamping members to complete the clamping action. By driving the clamping claw by the first driving member 2121, the tail clamping claw 212 can stably clamp the infusion pump 300.

[0055] Furthermore, a second driving member 214 is also provided on the tail material retrieving platform 200, and the second driving member 214 is fixed to the tail material retrieving platform 200. The second driving member 214 is arranged in the vertical direction, and the driving part of the second driving member 214 is connected to the fixing part 211 to drive the material retrieving assembly 210 to move in the vertical direction.

[0056] Specifically, the second driving member 214 is provided with an electric push rod or a telescopic cylinder, which is fixed to the tail material taking platform 200 by bolts, and the second driving member 214 is arranged in the vertical direction. The driving part of the second driving member 214 is connected to the fixing part 211 by bolts, thereby driving the material taking assembly 210 to move in the vertical direction. Thus, the fixing part 211 is driven to rise and fall by the second driving member 214 to adjust the height difference between each infusion device 300 to ensure that it can be safely wound.

[0057] Furthermore, the head material picking platform 100 and the tail material picking platform 200 both include a third driving member 215, a platform plate 216 and a lifting optical axis 217. The third driving member 215 is fixed to the platform plate 216. Several lifting optical axes 217 are arranged perpendicular to the platform plate 216. The top of the lifting optical axis 217 is connected to the driving end of the third driving member 215, and the bottom of the lifting optical axis 217 is connected to the material picking assembly 210. The lifting optical axis 217 and the third driving member 215 are both arranged in the vertical direction.

[0058] Specifically, the third driving member 215 can be set as an electric push rod or a telescopic cylinder. It is fixed to the platform plate 216 by bolts. A linear bearing is provided through the platform plate 216, and the lifting optical axis 217 is fixed to the linear bearing and moves in the vertical direction. The top of the lifting optical axis 217 is connected to the driving end of the third driving member 215 through a connecting member and a bolt, and the bottom of the lifting optical axis 217 is connected to the second driving member 214 in the material taking assembly 210. Thus, the tensioning mechanism is driven to rise or fall by the third driving member 215, so that the infusion set 300 can be separated from the carrier, which is convenient for its further winding.

[0059] Furthermore, the rear material-collecting platform 200 also includes a plurality of connecting plates 218, and the connecting plates 218 are arranged one by one corresponding to the material-collecting components 210. The second driving member 214 is fixed to the connecting plates 218, and the lifting optical axes 217 are arranged in groups of two on the platform plate 216. The lifting optical axes 217 of the same group are arranged along the extension direction of the connecting plates 218, and the connecting plates 218 are respectively connected to the bottom of the two lifting optical axes 217 of the same group.

[0060] Specifically, the connecting plate 218 is provided as a long rectangular plate, which is provided in the vertical direction and extends in the horizontal direction. The second driving member 214 is fixed to the front section of the connecting plate 218 by bolts. The rear end of the connecting plate 218 is respectively connected to the bottom bolts of the two lifting optical axes 217 of the same group. Thus, by providing two lifting optical axes 217 to drive one connecting plate 218 to lift the tensioning mechanism, the lifting stability of the infusion set 300 can be improved.

[0061] Preferably, the tail material collection platform 200 also includes a parallel plate 219, which is connected to the driving end of the third driving member 215, and two groups of lifting optical axes 217 are arranged on the platform plate 216 along a direction perpendicular to the extension direction of the carrier. The parallel plate 219 is respectively connected to the top of the two groups of lifting optical axes 217, and the two groups of lifting optical axes 217 are symmetrically arranged around the third driving member 215.

[0062] Specifically, the parallel plate 219 is arranged in the horizontal direction and is in the shape of a rectangular flat plate. The two sets of lifting optical axes 217 are respectively connected to the four corners of the parallel plate 219, and the middle of the parallel plate 219 is connected to the driving end of the third driving member 215. Therefore, by setting the parallel plate 219, the two sets of lifting optical axes 217 can be lifted together, reducing driving components, improving transmission efficiency, and reducing costs.

[0063] Furthermore, the feeding device of the infusion pump 300 also includes a staggered material collection platform 400, on which a second sliding track is arranged perpendicular to the extension direction of the infusion pump 300, and the tail material collection platform 200 is slidably arranged on the second sliding track.

[0064] Specifically, the dislocation material-collecting platform 400 is in the shape of a flat plate, and the second sliding track is fixed on the dislocation material-collecting platform 400 in a direction perpendicular to the extension direction of the infusion pump 300. The tail material-collecting platform 200 is slidably arranged on the second sliding track through a slider. Thus, the dislocation material-collecting is realized by sliding the tail material-collecting platform 200 on the second sliding track, that is, the two spaced material-collecting devices first clamp the infusion pump 300, rise to the winding position, and then translate through the second sliding track to avoid the transfer platform below the material-collecting assembly 210 to prevent interference with workpieces.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
