Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a nasal oxygen cannula assembly device. Background Technology

[0002] In medical settings, patients require nasal cannulas for oxygen delivery during treatment. Nasal cannulas consist of a fixing buckle, a cannula body, a three-way valve, an oxygen inhalation nasal plug, and the cannula body itself.

[0013] A method for assembling a nasal oxygen cannula, using the above-mentioned equipment, includes the following steps:

[0014] S1: The feeding mechanism is used to grab the nasal oxygen tube and place it on the conveyor line for conveying. The ends of the nasal oxygen tube are placed on the fork block and the clamp plate respectively, so that the two parts of the nasal oxygen tube are close to each other and far apart.

[0015] S2: The fixing buckle is assembled to the end of the nasal oxygen tube that is close to each other by the fixing buckle assembly mechanism, and the end that is far from each other is glued by the glue application mechanism.

[0016] S3: Use the first assembly mechanism to assemble the oxygen nasal plug onto the glued end of the nasal oxygen tube.

[0017] S4: Use the glue application mechanism to apply glue to the end of the nasal oxygen tube with the fixing buckle;

[0018] S5: Use the second assembly mechanism to assemble the three-way tube to the end of the nasal oxygen tube equipped with the fixing buckle, connect one end of the two parts of the nasal oxygen tube, and calibrate using the photoelectric calibrator.

[0019] S6: Apply adhesive to the end of the nasal oxygen cannula that is not fitted with an oxygen nasal plug using an adhesive applicator.

[0020] S7: Use the connecting mechanism to connect one part of the nasal oxygen cannula containing the oxygen nasal plug to the other part after applying adhesive, thus completing the assembly;

[0021] S8: Finally, the batch of nasal oxygen tubes that have been calibrated by the photoelectric calibrator are screened by the sorting mechanism, and the nasal oxygen tubes of good quality and poor quality are collected separately.

[0022] In summary, the present invention has the following beneficial effects:

[0023] 1. The present invention is provided with a feeding mechanism. When the second cylinder and the third cylinder drive the clamp to pick up the nasal oxygen tube and place it on the placement rack, the third cylinder makes the middle part of the nasal oxygen tube droop down and the whole body loose and not tight, so that there is enough space for operation when assembling the parts later, simplifying the operation and improving production efficiency.

[0024] 2. The present invention sets fork blocks and clamps on the conveyor line so that the two parts of one end of the nasal oxygen tube placed on the conveyor line are close together, while the two parts of the other end are far apart. This facilitates the simultaneous operation and assembly of different components at both ends. Furthermore, by assembling components of the nasal oxygen tube on both sides of the conveyor line at the same time, the production speed is accelerated, the production line length is shortened, and time and labor are saved.

[0025] 3. The present invention is equipped with a connecting mechanism. Using a pre-formed relaxed nasal oxygen tube, a portion of the nasal oxygen tube is rotated to another portion by a rotating clamp, and finally assembled. The whole process is automated, which not only saves manpower but also has high production efficiency. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] See Figure 1-12A nasal oxygen cannula assembly device includes a frame with a conveyor line 8 for transporting nasal oxygen cannulas. One end of the frame has a feeding mechanism 1 for placing the nasal oxygen cannulas, and the other end has a sorting mechanism 7. Along the conveying direction of the conveyor line 8, one side of the frame has a fixing buckle assembly mechanism 2, a gluing mechanism 3, and a second assembly mechanism 5 arranged sequentially. The other side has a gluing mechanism 3, a first assembly mechanism 4, and a connecting mechanism 6. One side of the conveyor line 8 has a fork block 81, and the other side has a clamping plate 82. The first assembly mechanism 4 is used to assemble the nasal plug, the second assembly mechanism 5 is used to assemble the three-way connector, and the connecting mechanism 6 is used to complete the assembly and connection of the nasal oxygen cannulas. First, the operator places the nasal oxygen cannula into the feeding mechanism 1, which then places it onto the conveyor line 8, ensuring the middle of the nasal oxygen cannula is in a drooping state. Simultaneously, the fork block 81 and the clamping plate 82 are used to... The two parts of the nasal oxygen tube are positioned with one end close to the other and the other end separated. The tube is then conveyed via conveyor line 8 to the fixing buckle assembly mechanism 2 for fixing buckle assembly. During fixing buckle assembly, glue is applied via glue application mechanism 3. These two mechanisms are existing technologies and will not be described in detail here. The tube is then conveyed to the first assembly mechanism 4 for nasal plug assembly, followed by the second assembly mechanism 5 for three-way tube assembly. One end of the two parts of the nasal oxygen tube is connected. Then, glue is applied to the other end of the tube without the nasal plug by glue application mechanism 3. The tube is then conveyed to the connecting mechanism 6 to insert the nasal plug into the glued portion, thus connecting the two parts of the nasal oxygen tube and completing the assembly. Finally, the sorting mechanism 7 separates the batch of nasal oxygen tubes that failed assembly from the batch that successfully assembled, completing the production of the nasal oxygen tube.

[0041] In some embodiments, the unloading mechanism 1 includes a first mounting frame 11, a first cylinder 12 is provided on the side of the first mounting frame 11 away from the machine frame, a clamping assembly 13 is provided on the telescopic part of the first cylinder 12, a placement frame 14 is provided below the first mounting frame 11, a placement groove 141 is provided at each end of the placement frame 14, and the spacing between the placement grooves 141 at each end is different, a container frame 15 is provided on one side of the placement frame 14, and the other side is close to the conveyor line 8.A gripper 16 is provided on the first mounting bracket 11 below the first cylinder 12. The clamping assembly 13 includes a connecting bracket 131, which is connected to the first cylinder 12. A second cylinder 132 is provided on the connecting bracket 131. A fixing bracket 133 is provided on the telescopic part of the second cylinder 132. A third cylinder 134 is provided on the fixing bracket 133. Both the third cylinder 134 and the fixing bracket 133 are provided with grippers 135. An automatic clamp 136 is provided on the connecting bracket 131 near the gripper 135. The gripper 135 includes a fourth cylinder 1351. Two movable clamping rods 1352 are provided on the fourth cylinder 1351. The 1352 system is centrally symmetrical and works in coordination. First, the operator places the nasal oxygen cannula into the holding frame 15. Except for the manual placement of the nasal oxygen cannula, all other controls are automatically controlled by a preset system program. This preset program is existing technology and will not be described in detail. The nasal oxygen cannula consists of two plastic tubes. Then, the gripper 16 is controlled to grasp one end of the nasal oxygen cannula. The gripper 16 is existing technology and will not be described in detail here. Next, the automatic clamp 136 is controlled to clamp the end of the nasal oxygen cannula. The automatic clamp 136 is existing technology and will not be described in detail here. This causes the first cylinder 12 to extend, driving the automatic clamp 136 to drag the nasal oxygen cannula onto the placement rack 14. The two parts of the nasal oxygen cannula are then... When the tubes are dragged onto the placement rack 14, the different spacing between the placement slots 141 at both ends of the rack 14 causes the two parts of one end of the nasal oxygen tube to be close to each other, while the other end is far apart. This facilitates subsequent operations on both ends of the nasal oxygen tube and speeds up production. Then, the first cylinder 12 is controlled to retract and reset, causing the automatic clamp 136 to pick up the ends of a batch of nasal oxygen tubes. At the same time, the two grippers 135 clamp the nasal oxygen tubes previously placed on the placement rack 14. The fourth cylinder 1351 pushes the two moving clamps 1352 to move in a staggered manner to clamp the nasal oxygen tubes. Then, the first cylinder 12 is controlled to extend, and the automatic clamp 136 drags the nasal oxygen tubes onto the placement rack. When the nasal oxygen cannula is placed on the rack 14, two grippers 135 together clamp it and transport it to the fork block 81 and clamping plate 82 of the conveyor line 8. Because the fork block 81 and clamping plate 82 have different spacing, the nasal oxygen cannula is transported on the conveyor line 8 in the same state as it is on the rack 14: one end of the nasal oxygen cannula is close to the other, and the other end is separated. Finally, the third cylinder 134 extends, moving the gripper 135 closest to the conveyor line 8 towards the other gripper 135, thus relaxing the nasal oxygen cannula from a taut state to a relaxed state. This allows for sufficient space during subsequent component assembly, increasing production speed.

[0042] In some embodiments, the first assembly mechanism 4 includes a second mounting frame 41, on which a fifth cylinder 43 is mounted. An assembly assembly 46 is mounted on the telescopic portion of the fifth cylinder 43. A first fixing assembly 44 is mounted on one side of the second mounting frame 41 near the conveyor line 8, and a first unloading chute 42 is mounted on the other side. A temporary storage assembly 45 is mounted on the second mounting frame 41 between the first unloading chute 42 and the first fixing assembly 44. The assembly assembly 46 includes a movable frame 461, which is slidably connected to the second mounting frame 41. A sixth cylinder 464 is mounted inside the movable frame 461, and an electric clamp 465 is mounted on the telescopic portion of the sixth cylinder 464. A seventh cylinder 462 is mounted on the movable frame 461 near the first fixing assembly 44. The telescopic part is equipped with a lifting clamp 463. When the nasal oxygen tube is coated with adhesive and transported to the first assembly mechanism 4 by the conveyor line 8, the operator or the existing system presets to first control the sixth cylinder 464 to extend and drive the electric clamp 465 to pick up the oxygen nasal plug placed in the first feeding trough 42. At the same time, control the seventh cylinder 462 to extend and drive the lifting clamp 463 to lower and pick up the oxygen nasal plug placed in the temporary storage component 45. Then control the fifth cylinder 43 to extend and drive the moving frame 461 to move towards the conveyor line 8. Subsequently, the seventh cylinder 462 drives the lifting clamp 463 to assemble the oxygen nasal plug onto the adhesive nasal oxygen tube. The electric clamp 465 also places another batch of oxygen nasal plugs into the temporary storage component 45. This process is repeated to assemble the oxygen nasal plugs onto the nasal oxygen tube without interruption, which is convenient and fast.

[0043] In some embodiments, the temporary storage component 45 includes a support 451 with a temporary storage slot and a blocking member 452. Before the electric clamp 465 places the oxygen nasal plug into the temporary storage slot of the support 451, the blocking member 452 is controlled to block the opening of the temporary storage slot facing the first fixing component 44 to prevent the oxygen nasal plug from falling during placement. When the lifting clamp 463 moves to the support 451 and picks up the oxygen nasal plug, the blocking member 452 is controlled to stop blocking, ensuring that the oxygen nasal plug is successfully picked up by the lifting clamp 463.

[0044] In some embodiments, the second assembly mechanism 5 includes a third mounting frame 51, on which an eighth cylinder 53 is mounted. The telescopic part of the eighth cylinder 53 is equipped with an electric push rod 54, and the electric push rod 54 is equipped with a push clamp 541. A second fixing component 56 is mounted on one side of the third mounting frame 51 near the conveyor line 8, and a second feeding groove 52 is mounted on the other side. When the nasal oxygen tube body is transported to the second assembly mechanism 5 by the conveyor line 8 after being equipped with the oxygen nasal plug, the operator or the existing system presets the control of the second fixing component 56 to fix the nasal oxygen tube body. The second fixing component 56 is an existing clamp, which will not be described in detail here. Then, the electric push rod 54 drives the push clamp 541 to clamp the three-way tube that is conveyed from the second feeding groove 52. Subsequently, the eighth cylinder 53 is controlled to extend and push the electric push rod 54 to move towards the nasal oxygen tube body, so that the electric push rod 54 drives the push clamp 541 to assemble the three-way tube onto the end of the nasal oxygen tube body equipped with the fixing buckle, thus completing the assembly of the fixing buckle.

[0045] In some embodiments, a clamping frame 521 is provided at one end of the second feeding trough 52 near the second fixing component 56. A photoelectric calibrator 522 is provided on the clamping frame 521. A ninth cylinder 55 is provided at the end of the second feeding trough 52 below the clamping frame 521. A blocking frame 551 is provided on the ninth cylinder 55. The blocking frame 551 is located at one end of the clamping frame 521 near the conveyor line 8. A tenth cylinder 552 is provided on the side of the ninth cylinder 55. When a set of fixing buckles is clamped and assembled by the push clamp 541, the operator or the existing system presets the control to retract the tenth cylinder 552 to drive the ninth cylinder 55 to move laterally. Then, the ninth cylinder 55 drives the blocking frame 551 to move laterally to block the end of the clamping frame 521 near the conveyor line 8, preventing the new set of fixing buckles conveyed to the clamping frame 521 from slipping off. It can also cooperate with the photoelectric calibrator 522 to perform calibration, ensuring that the push clamp 541 can smoothly clamp the T-tube.

[0046] In some embodiments, the connecting mechanism 6 includes a fourth mounting bracket 61 connected to the conveyor line 8. An eleventh cylinder 62 is mounted on the fourth mounting bracket 61, and a mounting seat 63 is mounted on the eleventh cylinder 62. The mounting seat 63 is slidably connected to the fourth mounting bracket 61. A movable plate 65 is slidably connected to the mounting seat 63. A twelfth cylinder 64 is mounted on the side of the movable plate 65, and a rotating clamp 66 is mounted on the movable plate 65. A third fixing component 67 is mounted on the fourth mounting bracket 61 near the conveyor line 8. A pressing component 68 and an pushing component 69 are mounted on the fourth mounting bracket 61 between the third fixing component 67 and the conveyor line 8. While the nasal oxygen tube is being assembled with a three-way connector, the other end is coated with adhesive by the adhesive applicator 3 onto a portion of the unassembled nasal plug. The nasal oxygen tube is then conveyed by the conveyor line 8 to the connecting mechanism 6 and connected by the third fixing component 67. Once secured, the operator or the existing system presets the pusher 69 to push the nasal oxygen cannula off the clamp 82, loosening it. The pusher 69 is a combination of a cylinder and a pusher plate, which will not be described in detail here. Next, the eleventh cylinder 62 is extended, causing the mounting base 63 to drive the rotating clamp 66 to clamp the part of the nasal oxygen cannula equipped with the oxygen nasal plug. Then, the eleventh cylinder 62 is retracted, moving it away from the third fixing component 67. The rotating clamp 66 is then rotated, and the twelfth cylinder 64 pushes the moving plate 65 laterally on the mounting base 63, so that the part of the nasal oxygen cannula equipped with the oxygen nasal plug faces the glued end. Finally, the eleventh cylinder 62 is extended, and the rotating clamp 66 is used to insert the part of the nasal oxygen cannula equipped with the oxygen nasal plug into the glued part, connecting the two parts together, thus completing the assembly of the nasal oxygen cannula.

[0047] A method for assembling a nasal oxygen cannula, using the above-mentioned equipment, includes the following steps:

[0048] S1: The feeding mechanism 1 is used to grab the nasal oxygen tube and place it on the conveyor line 8 for conveying. The ends of the nasal oxygen tube are placed on the fork block 81 and the clamping plate 82 respectively, so that the two parts of the nasal oxygen tube are close to each other and far apart.

[0049] S2: The fixing buckle is assembled to the end of the nasal oxygen tube that is close to each other by the fixing buckle assembly mechanism 2, and the glue is applied to the end that is far away from each other by the glue application mechanism 3.

[0050] S3: Use the first assembly mechanism 4 to assemble the oxygen nasal plug to the glued end of the nasal oxygen tube.

[0051] S4: Use the glue application mechanism 3 to apply glue to the end of the nasal oxygen tube with the fixing buckle;

[0052] S5: Use the second assembly mechanism 5 to assemble the three-way tube to the end of the nasal oxygen tube equipped with the fixing buckle, connect one end of the two parts of the nasal oxygen tube, and perform calibration using the photoelectric calibrator 522.

[0053] S6: Apply adhesive to the end of the nasal oxygen cannula that is not fitted with an oxygen nasal plug using the adhesive application mechanism 3;

[0054] S7: Use the connecting mechanism 6 to connect one part of the nasal oxygen tube containing the oxygen nasal plug to the other part after applying adhesive, thus completing the assembly;

[0055] S8: Finally, the batch of nasal oxygen tubes that have been calibrated to be qualified by the photoelectric calibrator 522 is screened by the sorting mechanism 7, and the nasal oxygen tubes of good quality and poor quality are collected separately.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
