Description

Technical Field

[0001] This invention relates to the field of oxygen delivery tube assembly technology, and in particular to a fully automatic oxygen delivery tube assembly machine. Background Technology

[0002] Medical tubing consumables include oxygen tubing, suction tubing, and infusion tubing. To facilitate transportation and reduce space occupation, currently used medical tubing consumables are all packaged after being wound.

[0003] Chinese patent CN214357185U discloses an oxygen delivery tube coiling device, comprising: a frame; and a winding machine including a base platform, a winding column, and a rotary drive device. The base platform is horizontally and rotatably installed within the frame. The winding column extends and retracts through the base platform. When the winding column extends beyond the upper surface of the base platform and rotates, it can wind a straight oxygen delivery tube with one end placed inside into a coil. In use, the winding column extends beyond the base platform and rotates to wind the tube. After winding, it retracts back to the base platform for immediate unloading. The mechanical structure is simple and the operation is straightforward. The wound coil is removed by the unloading device, and a transfer device drives its movement, allowing the winding machine to perform the next winding without intermediate stops. This greatly improves efficiency and reduces potential pollution from manual operation.

[0004] Although the above-mentioned device can quickly complete the coiling operation of the oxygen delivery tube by winding the column, in actual application, the lengths extending from the two ends of the coil are often different, which affects the subsequent processes such as coating and packaging the coil. Therefore, the coil needs to be processed again to make the lengths extending from both ends equal. In summary, the above-mentioned device still has room for improvement.

[0005] Therefore, it is necessary to provide a fully automated assembly machine for oxygen delivery tubes to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a fully automatic assembly machine for oxygen delivery tubes, in order to solve the problem mentioned in the background art that although the existing device can quickly complete the coiling operation of oxygen delivery tubes by winding the column, in actual application, the lengths of the two ends of the coil are often different, which affects the subsequent processes such as gluing and packaging of the coil.

[0007] Based on the above ideas, the present invention provides the following technical solution: a fully automatic assembly machine for oxygen delivery tubes, including a support plate and a vertical shaft set on the top of the support plate. A sleeve is sleeved on the outside of the vertical shaft, and a turntable is sleeved on the outside of the sleeve. Multiple slots are evenly opened on the outer circumference of the turntable. Clamping units are respectively provided at both ends of the oxygen delivery tube. The clamping unit at one end of the oxygen delivery tube is connected to the traction component on the turntable, and a stop component is provided at the clamping unit at the other end of the oxygen delivery tube.

[0008] The top of the turntable is equipped with multiple limiting rods. When the vertical shaft drives the sleeve to rotate, it can wind the oxygen delivery tube. When the oxygen delivery tube moves the stop assembly at one end to the turntable, the stop assembly can limit the turntable and prevent it from continuing to rotate. When the clamping units at both ends of the oxygen delivery tube come into contact with the same limiting rod, the sleeve stops rotating.

[0009] As a further aspect of the present invention: the limiting rod is set to an arc shape, and the center of the limiting rod is collinear with the axis of the sleeve.

[0010] As a further aspect of the present invention: the clamping unit includes a base plate and clamping blocks disposed on both sides of the top of the base plate, the clamping blocks being elastically connected to the base plate, and a connecting rod being fixedly disposed at the bottom of the base plate.

[0011] As a further embodiment of the present invention: the traction assembly includes a slider elastically connected to a turntable, the turntable having a through slot, the slider being slidably disposed within the slot, a locking block elastically disposed on one side of the slider, a groove cooperating with the locking block being formed on the inner wall of the slot, a counterweight being slidably disposed within the slider, a pull rope being fixedly disposed between the counterweight and the locking block, and multiple locking teeth being fixedly disposed on the side wall of the slot near the groove, the locking teeth being inclined, and a connecting rod located above the turntable being fixedly connected to the slider.

[0012] As a further aspect of the present invention: the stop assembly includes a base, a connecting block is slidably disposed inside the base, the connecting block is U-shaped, and a sliding rod is elastically connected to the top of the connecting block. Upright plates are fixedly disposed on both the front and rear sides of the top of the sliding rod, and a positioning groove that cooperates with the base plate is provided on the inner side of the upright plate.

[0013] As a further aspect of the present invention: the top of the turntable is provided with an arc-shaped groove that cooperates with the limiting rod, and a limiting groove is provided on the inner peripheral wall of the arc-shaped groove. The limiting groove is inclined, and a limiting block that slides with the limiting groove is fixedly provided on the peripheral wall of the limiting rod. The end of the limiting rod that extends into the through groove is provided with an inclined surface.

[0014] As a further aspect of the present invention: a guide groove is provided on the slider, the counterweight is slidably disposed in the guide groove, and the top of the counterweight extends to the outside of the slider.

[0015] As a further embodiment of the present invention, a support ring is fixedly provided on the outer side of the vertical axis.

[0016] As a further aspect of the present invention: a retaining ring is fixedly sleeved on the outer side of the sleeve, and the retaining ring is located above the turntable.

[0017] As a further aspect of the present invention: a first protrusion is elastically provided on the inner wall of the sleeve, a first limiting hole that cooperates with the first protrusion is provided on the outer circumferential surface of the vertical shaft, a second protrusion is elastically provided on the inner wall of the turntable, a second limiting hole that cooperates with the second protrusion is provided on the outer circumferential surface of the sleeve, and the end of the first protrusion near the vertical shaft and the end of the second protrusion near the sleeve are both set as spherical surfaces.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This device sets multiple limiting rods. When the connecting rods and sliders at both ends of the oxygen delivery tube approach the same limiting rod, the limiting rods can limit the connecting rods and sliders to prevent them from moving. This ensures that both ends of the oxygen delivery tube are on the same circumference, thereby ensuring that the lengths left at both ends of the oxygen delivery tube during the winding process are equal. This avoids secondary processing of the oxygen delivery tube in the later stage and helps to improve the efficiency of oxygen delivery tube assembly. Attached Figure Description

[0036] like Figure 1-4 As shown, an automatic assembly machine for oxygen delivery tubes includes a frame 1 and a tube winding mechanism 2 mounted on the frame 1.

[0037] As one embodiment of the tube winding mechanism 2, it includes a motor 3 connected to the frame 1. The output shaft of the motor 3 is connected to a base via belt drive or chain drive, etc. A support plate 5 is fixedly installed on the top of the base. A cam 4 is installed on the top of the support plate 5. In actual use, one end of the oxygen delivery tube 8 is wrapped around the cam 4, and the end of the oxygen delivery tube 8 is fixed by the clamps or other structures on the support plate 5. At this time, the cam 4 can be wound around the tube by rotating the motor 3.

[0038] However, in actual use, the lengths of the two ends of the wound oxygen delivery tube 8 are not the same. To solve this problem, this solution designs another embodiment of the winding mechanism 2. A vertical shaft 6 is fixedly installed on the top of the support plate 5. A sleeve 7 is sleeved on the outside of the vertical shaft 6, and a turntable 14 is sleeved on the outside of the sleeve 7. The turntable 14 can rotate with the sleeve 7 through a bearing. Multiple slots 22 are evenly opened on the outer circumference of the turntable 14. Clamping units are respectively provided at both ends of the oxygen delivery tube 8. The clamping unit at one end of the oxygen delivery tube 8 is connected to the traction component on the turntable 14, and the clamping unit at the other end of the oxygen delivery tube 8 is provided with a stop component.

[0039] Multiple limiting rods 13 are provided on the top of the turntable 14. All limiting rods 13 are arc-shaped, and the center of the limiting rod 13 is collinear with the axis of the sleeve 7. In actual use, when the vertical shaft 6 drives the sleeve 7 to rotate, it can wind the oxygen delivery tube 8. When the oxygen delivery tube 8 moves the stop assembly at one end to the turntable 14, the stop assembly can limit the turntable 14 to prevent it from rotating. At this time, the vertical shaft 6 can drive the sleeve 7 to rotate independently, thereby adjusting the oxygen delivery tube 8 wound on the outside of the sleeve 7. When the clamping units at both ends of the oxygen delivery tube 8 come into contact with the same limiting rod 13, the sleeve 7 stops rotating. At this time, the lengths extended from both ends of the wound oxygen delivery tube 8 are the same.

[0040] like Figure 2-7 As shown in Figures 9-13, the clamping unit includes a base plate 23 and clamping blocks 18 disposed on both sides of the top of the base plate 23. The clamping blocks 18 are elastically connected to the base plate 23. A connecting rod 24 is fixedly disposed at the bottom of the base plate 23. In actual use, the end of the oxygen delivery tube 8 is placed between the two clamping blocks 18, and the clamping blocks 18 can clamp the oxygen delivery tube 8.

[0041] The traction assembly includes a slider 16 elastically connected to the turntable 14. Specifically, a through slot is provided on the turntable 14, and the slider 16 is slidably disposed in the through slot. A locking block 31 is elastically disposed on one side of the slider 16, and a groove 32 that cooperates with the locking block 31 is provided on the inner wall of the through slot. When the locking block 31 pops out and is placed inside the groove 32, the slider 16 is locked to the turntable 14. A counterweight 29 is also slidably disposed in the slider 16. A pull rope 30 is fixedly disposed between the counterweight 29 and the locking block 31. The pull rope 30 passes through the slider 16 and slidably cooperates with it.

[0042] Furthermore, a plurality of locking teeth 21 are fixedly provided on one side wall of the through groove near the groove 32. The locking teeth 21 are inclined. When the locking block 31 on the slider 16 pops out and engages with the locking teeth 21, the slider 16 can only slide outward in one direction within the through groove.

[0043] The stop assembly includes a base 11, and a connecting block 19 is slidably disposed inside the base 11. The connecting block 19 is U-shaped, and a sliding rod 9 is elastically connected to the top of the connecting block 19. Vertical plates 20 are fixedly disposed on the front and rear sides of the top of the sliding rod 9, and the clamping unit at one end of the oxygen delivery tube 8 is located between the two vertical plates 20. A positioning groove 35 that cooperates with the base plate 23 is opened on the inner side of the vertical plate 20.

[0044] Furthermore, in order to neatly wind the oxygen delivery tube 8 onto the sleeve 7, the base 11 needs to gradually move upward during the winding process. Therefore, a hydraulic rod is provided below the base 11. The hydraulic rod is installed on the frame 1, and the telescopic end of the hydraulic rod is fixedly connected to the base 11. In actual application, when the hydraulic rod drives the base 11 to move upward to the highest point, the connecting rod 24 at the bottom of the support plate 5, which cooperates with the vertical plate 20, is located above the turntable 14, so that the bottom of this connecting rod 24 can fit against the turntable 14 during the movement of the oxygen delivery tube 8.

[0045] like Figure 3 , 7 As shown, the top of the turntable 14 has an arc-shaped groove that cooperates with the limiting rod 13, and a limiting groove 27 is provided on the inner peripheral wall of the arc-shaped groove. The limiting groove 27 is inclined. A limiting block 28 is fixedly provided on the peripheral wall of the limiting rod 13, which slides in cooperation with the limiting groove 27, so that the limiting block 28 is slidably disposed in the limiting groove 27. One end of the limiting rod 13 extending into the through groove is provided with an inclined surface, so that the slider 16 can squeeze the limiting rod 13 to move in the arc-shaped groove during the sliding process. Through the cooperation of the limiting block 28 and the limiting groove 27, the limiting rod 13 can move upward during the movement.

[0046] For the connection between the vertical shaft 6 and the sleeve 7, such as Figure 12 As shown, a first protrusion 33 is elastically provided on the inner wall of the sleeve 7, and a first limiting hole that cooperates with the first protrusion 33 is provided on the outer circumferential surface of the vertical shaft 6. A second protrusion 34 is elastically provided on the inner wall of the turntable 14, and a second limiting hole that cooperates with the second protrusion 34 is provided on the outer circumferential surface of the sleeve 7. The end of the first protrusion 33 near the vertical shaft 6 and the end of the second protrusion 34 near the sleeve 7 are both spherical.

[0047] In practical applications, the connecting rod 24 located above the turntable 14 is fixedly connected to the slider 16. The two ends of the oxygen delivery tube 8 to be wound are placed between the two clamping blocks 18. The ends of the oxygen delivery tube 8 are fixed by the clamping blocks 18. The sleeve 7 is sleeved on the outside of the vertical shaft 6, so that the first protrusion 33 is connected to the first limiting hole. The clamping unit at the other end of the oxygen delivery tube 8 is placed between the two clamping blocks 18, so that the base plate 23 and the positioning groove 35 slide together. At this time, the motor 3 drives the support plate 5 and the vertical shaft 6 to rotate. The vertical shaft 6 can drive the sleeve 7 to rotate. Since the slider 16 is locked in the through groove by the cooperation of the locking block 31 and the groove 32, the sleeve 7 can be wound around the oxygen delivery tube 8 when it rotates. During this process, the hydraulic rod drives the base 11 to move upward, which is conducive to the neat winding of the oxygen delivery tube 8 around the outside of the sleeve 7.

[0048] As the oxygen delivery tube 8 continuously winds around the outside of the sleeve 7, the connecting block 19 can be pulled closer to the turntable 14 through the oxygen delivery tube 8. When one side of the connecting block 19 is inserted into the slot 22, the connecting block 19 can limit the turntable 14, thereby preventing the turntable 14 from continuing to rotate. At this time, the sleeve 7 can continue to rotate by the cooperation of the first protrusion 33 and the first limiting hole, while the spherical surface on the second protrusion 34 is pressed against the second limiting hole, thereby causing the second protrusion 34 to move out of the second limiting hole. When the turntable 14 stops rotating, the counterweight 29 will still slide a distance along the original rotation trajectory under the inertial force, thereby pulling the locking block 31 through the pull rope 30, causing the locking block 31 to retract to the slider 16, so that the slider 16 can move outward through the slot. At this point, the turntable 14 stops rotating, the slider 16 can slide outward along the slot, and the multiple locking teeth 21 can prevent the slider 16 from resetting.

[0049] As the sleeve 7 continues to rotate, it continues to wind the section of the oxygen delivery tube 8 near the base 11, while the section of the oxygen delivery tube 8 away from the base 11 is gradually released. During this process, the slider 16 at one end of the oxygen delivery tube 8 slides outward along the through groove and squeezes multiple limiting rods 13, causing the limiting rods 13 to slide away from the slider 16. Meanwhile, the connecting rod 24 at the other end of the oxygen delivery tube 8 slides along the surface of the turntable 14. Since the limiting rods 13 are initially placed in the arc-shaped groove and their top surfaces are flush with the top surface of the turntable 14, the connecting rod 24 can slide along the surface of the turntable 14 towards the vertical axis 6. When the sliders 16 and connecting rods 24 at both ends of the oxygen delivery tube 8 approach the same limiting position... When the rod 13 is in motion, the slider 16 can press the limiting rod 13 to slide. Through the cooperation of the limiting groove 27 and the limiting block 28, the limiting rod 13 can move upward and protrude from the surface of the turntable 14 during the sliding process. At this time, the protruding limiting rod 13 can block the connecting rod 24 and prevent it from continuing to move, so that the two ends of the oxygen delivery tube 8 are on the same circumference. Thus, both ends of the oxygen delivery tube 8 are in a limited state and difficult to move, so that the vertical shaft 6 is difficult to drive the sleeve 7 to continue to rotate during the rotation and is in a state of rotating alone. Since the center of the limiting rod 13 and the axis of the sleeve 7 are collinear, the distances extended by the two ends of the oxygen delivery tube 8 are equal at this time. Then the turntable 14 and the sleeve 7 can be removed together.

[0050] In summary, this device, by setting multiple limiting rods 13, can limit the movement of the connecting rods 24 and sliders 16 at both ends of the oxygen delivery tube 8 when they approach the same limiting rod 13, thus preventing them from moving. This ensures that both ends of the oxygen delivery tube 8 are on the same circumference, thereby guaranteeing that the lengths left at both ends of the oxygen delivery tube 8 during the winding process are equal, avoiding secondary processing of the oxygen delivery tube 8 in the later stages, and improving the efficiency of assembling the oxygen delivery tube 8.

[0051] like Figure 3-7 As shown, a connecting shaft is fixedly installed in the through groove. The connecting shaft passes through the slider 16 and slides with it. A vertical plate is fixedly installed at the bottom of the turntable 14 on one side of the through groove. A limit spring 15 is fixedly installed between the vertical plate and the slider 16 to realize the elastic connection between the slider 16 and the turntable 14.

[0052] The inner wall of the through groove is recessed inward to form a rectangular groove, and the locking tooth 21 is located in the rectangular groove to avoid interference between the slider 16 and the locking tooth 21 when sliding.

[0053] The slide bar 9 is U-shaped, and the connecting block 19 has a first sliding groove that slides with the slide bar 9. A guide rod 10 is fixedly installed on the connecting block 19. The guide rod 10 passes through the slide bar 9 and slides with it. A first spring is sleeved on the outside of the guide rod 10. The first spring is fixedly installed between the slide bar 9 and the connecting block 19. When the connecting block 19 is engaged with the slot, the oxygen delivery tube 8 can still pull the upright plate 20 to slide relative to the connecting block 19 during the winding process.

[0054] like Figure 8 As shown, a second sliding groove is provided on the top of the base plate 23. A protrusion 25 is fixedly connected to the bottom of the clamping block 18. The protrusion 25 is slidably disposed in the second sliding groove, and a crossbar 26 is fixedly disposed inside the second sliding groove. The crossbar 26 passes through the protrusion 25 and slides with it. A second spring is provided between the outer side of the protrusion 25 and the side of the second sliding groove to realize the elastic connection between the clamping block 18 and the base plate 23. Of course, in actual application, different structures can also be used to clamp the end of the oxygen delivery tube 8. For example, a cylinder can be installed on the base plate 23, and the clamping block 18 can be pushed by the cylinder to clamp the end of the oxygen delivery tube 8.

[0055] like Figure 11 As shown, a guide groove is provided on the slider 16, and the counterweight 29 is slidably disposed in the guide groove. The top of the counterweight 29 can extend to the outside of the slider 16. A reset spring can be installed on the inner wall of the guide groove, which is beneficial for limiting the initial position of the counterweight 29. A square groove is provided on the side of the slider 16, and the locking block 31 is slidably disposed in the square groove. A third spring is fixedly disposed between the inner end face of the square groove and the locking block 31. When the turntable 14 starts to rotate, the counterweight 29 will move towards the locking block 31. When the turntable 14 stops rotating, the counterweight 29 will continue to move a distance under the action of inertia, and then pull the locking block 31 through the pull rope 30.

[0056] like Figure 12As shown, mounting grooves are provided on the inner wall of the sleeve 7 and the inner wall of the turntable 14, and the first protrusion 33 and the second protrusion 34 are slidably disposed in the mounting grooves. Springs are fixedly disposed between the first protrusion 33 and the inner end face of the mounting groove, and between the second protrusion 34 and the inner end face of the mounting groove.

[0057] A support ring 17 is fixedly installed on the outside of the vertical shaft 6. The support ring 17 is located at the bottom of the sleeve 7 and is used to support the sleeve 7.

[0058] A retaining ring 12 is fixedly sleeved on the outside of the sleeve 7. The retaining ring 12 is located above the turntable 14 and is used to support the wound oxygen delivery tube 8.

[0059] like Figure 14-15 As shown, a baffle 36 is hinged to one end of the base 11 near the turntable 14. A semi-circular hole is provided on the baffle 36. When the two baffles 36 are aligned, the oxygen delivery tube 8 can pass through the gap between the two baffles 36, so that the oxygen delivery tube 8 can move stably upward when the base 11 moves upward.

[0060] An arc-shaped rod 37 is fixedly installed on the outer side of the baffle 36, and an arc-shaped sliding sleeve is fixedly installed on the outer side of the base 11. The center of the sliding sleeve and the arc-shaped rod 37 are both coincident with the rotation axis of the baffle 36. One end of the arc-shaped rod 37 is slidably installed in the sliding sleeve, and an arc-shaped spring is fixedly installed between the inner end face of the sliding sleeve and the arc-shaped rod 37.
