Detailed Implementation
[0020] To illustrate the technical content, structural features, objectives, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0021] Please refer to the fully automatic nasal oxygen cannula assembly machine. Figure 1-32 As shown, it includes: a first assembly line A1, a second assembly line B1, and a handling robot C1; like Figure 2 As shown, the first assembly line A1 is mainly for feeding branch pipes, installing fixing rings, and installing nose brackets. The second assembly line B1 is mainly for feeding main pipes. The handling robot C1 moves the semi-finished products assembled in the first assembly line A1 to the second assembly line B1. At the same time, the handling robot C1 assembles the main pipe 03 and the semi-finished products.
[0022] Here, a semi-finished product refers to a product assembled from two branch tubes, a fixing ring, and a nose bridge.
[0023] like Figure 3 As shown, the first assembly line A1 includes: a branch pipe feeding device A100, a fixing ring assembly device A200, a three-way valve assembly device A300, a nose bridge feeding device A400, and a nose bridge assembly device A500 arranged in sequence. It also includes a first transmission line group A600, wherein the first transmission line group A600 drives the branch pipe O2 to be transmitted at each station of the first assembly line A1.
[0024] like Figure 20 As shown, the second assembly line B1 includes: a main pipe feeding device B100, a horn connector feeding device B200 and a drying device B400 arranged in sequence, and also includes a second transmission line group B500, wherein the second transmission line group B500 drives the main pipe 03 to be transported at each station of the second assembly line B1. The handling robot C1 moves the semi-finished products assembled in the first assembly line A1 to the second assembly line B1.
[0025] The nose bridge assembly device A500 includes: a nose bridge positioning mechanism 100 for positioning the nose bridge 01, a branch tube positioning mechanism 200 for positioning the branch tube 02, and a feeding mechanism 300; the feeding mechanism 300 bends the branch tube 02 and inserts it into the nose bridge 01. The nose bridge positioning mechanism 100 includes: a first support 110, a first lifting assembly 120 assembled on the first support 110, and multiple nose bridge clamp assemblies 130 driven by the first lifting assembly 120 to move in the Z direction, wherein the nose bridge clamp assembly 130 clamps the nose bridge 01 when closed. The branch pipe positioning mechanism 200 includes: a branch pipe clamp assembly 210; when the branch pipe clamp assembly 210 is closed, it forms a through hole for the branch pipe 02 to pass through; The feeding mechanism 300 inserts the nose bridge 01 from the nose bridge positioning mechanism 100 into the branch tube 02 and bends the branch tube 02.
[0026] In this embodiment, the nose clip assembly 130 is provided with four sets, the branch tube clip assembly 210 is provided with four sets, and during assembly, there are a total of eight branch tubes 02 and four nose clips 01. Two branch tubes 02 are used in conjunction with one nose clip 01 for assembly, and the two branch tubes 02 are respectively inserted into the two ends of the nose clip 01.
[0027] like Figure 12 As shown, eight branch tubes 02 are placed in the same direction and on the same side. The front ends of four branch tubes 02 have been inserted into the nose bridge 01. The branch tubes 02 that have been inserted into the nose bridge 01 and the branch tubes 02 that have not been inserted into the nose bridge 01 are arranged alternately. Below, the branch tube 02 that has been inserted into the nose clip 01 is defined as a branch tube installed, and the branch tube 02 that has not been inserted into the nose clip 01 is defined as a branch tube not installed. During assembly, the nose bridge 01 is positioned at the nose bridge positioning mechanism 100, the branch tube positioning mechanism 200 clamps the installed branch tube, the feeding mechanism 300 clamps the front end of the uninstalled branch tube, and the uninstalled branch tube is bent 180°. Then, the front end of the uninstalled branch tube is inserted into the other end of the nose bridge 01, thus completing the assembly of the nose bridge.
[0028] It should be noted that before assembly, the nose bridge 01 is first assembled with one of the branch tubes 02 by the nose bridge feeding device A400 to form an installed branch tube, and then sent to the nose bridge assembly device for assembly between the uninstalled branch tube and the nose bridge 01.
[0029] In one embodiment, the first lifting assembly 120 includes: a lifting cylinder 121, a lifting mounting plate 122 mounted on the drive shaft of the lifting cylinder 121, and multiple nose clip assemblies 130 mounted on the lifting mounting plate 122. A set of nose clip assemblies 130 has a set of nose clip bodies 131, and when the nose clip bodies 131 are closed, their tops form a receiving groove 1311 for receiving the nose clip 01.
[0030] The four sets of nose clip assemblies 130 mentioned above are arranged along the X direction on the lifting mounting plate 122. When the lifting cylinder 121 drives the lifting mounting plate 122 to rise and fall, the four sets of nose clip assemblies 130 rise and fall synchronously. The nose bridge 01 is placed in the receiving slot 1311 and clamped.
[0031] Furthermore, limiting plates 132 are provided at both the front and rear ends of the receiving slot 1311. The top of the limiting plate 132 is V-shaped and the limiting plate 132 is also used to support the nose bridge 01. Before the nose clip 01 is placed into the receiving slot 1311, the nose clip body 131 is open. The nose clip 01 is first placed on top of the two limiting plates 132 and supported on the limiting plates 132. Then the nose clip body 131 closes to hold the nose clip 01, preventing the nose clip 01 from shifting when the branch tube is inserted later.
[0032] The nose bridge positioning mechanism 100 also includes a material plate 140, and a clamp 141 is provided at the front end of the nose bridge clamp assembly 130. When the clamp 141 is closed, it forms a hole through which the unattached branch tube can pass, but the inner diameter of the hole is smaller than the outer diameter of the nose bridge 01, so as to prevent the nose bridge 01 from moving forward through the hole of the clamp 141.
[0033] In one implementation, such as Figure 12 and Figure 16 As shown, the feeding mechanism 300 includes: a second bracket 310, a slide plate 320, multiple sets of branch pipe moving assemblies 330, a rotating assembly 340, and a mounting plate 350; the rotating assembly 340 is mounted on the mounting plate 350, and the slide plate 320 is driven by the driving assembly to move the rotating assembly 340 together along the Y direction; the mounting plate 350 is mounted on the slide plate 320 and can move along the Z direction; the branch pipe moving assembly 330 is connected to the rotating assembly 340.
[0034] like Figure 12 As shown, the second bracket 310 is provided with a Y-direction guide rail, the slide plate 320 is mounted on the guide rail and driven by the drive assembly to move together with the rotating assembly 340 in the Y direction; the slide plate 320 is provided with a Z-direction guide rail, the mounting plate 350 is mounted on the Z-direction guide rail and driven by the drive assembly to move in the Z direction.
[0035] Furthermore, continue as Figure 16 As shown, the branch pipe moving assembly 330 has a moving clamp 331, which can open and close; The rotating assembly 340 includes: a motor 341, a belt drive assembly 342, and a rotating shaft 343; the branch pipe moving assembly 330 is connected to the rotating shaft 343, and the rotating assembly 340 drives the branch pipe moving assembly 330 to rotate.
[0036] Furthermore, the belt drive assembly 342 includes: a drive pulley 3421, a plurality of driven pulleys 3422 and a belt 3423; each driven pulley 3422 is mounted on a rotating shaft 343; the rotating shaft 343 is mounted on a mounting plate 350.
[0037] In use, the movable clamp 331 closes and clamps the front end of the pipe that is not installed, such as... Figure 13 As shown, the installed branch tube is located on the right side, and the uninstalled branch tube is located on the left side and clamped by the moving clamp 331. The motor 341 drives the rotating component 340 to rotate 180° through the belt drive assembly 342, so that the front end of the uninstalled branch tube rotates 180° and is aligned with the front end of the nose bridge 01. Then, under the drive of the drive assembly, the branch tube moving component 330 moves along the Y direction and inserts into the front end of the nose bridge 01, thus completing the assembly.
[0038] Furthermore, the first transmission line group A600 is provided with a branch pipe limiting seat 400, with one branch pipe limiting seat 400 provided for each branch pipe 02; the number of branch pipe limiting seats 400 is twice that of the nose bridge positioning mechanism 100. The branch tube limit seat 400 supports the branch tube 02 to prevent it from deviating. After the nose frame 01 is assembled, the nasal oxygen tube with the assembled nose frame 01 is transferred to the next work station by the rotation of the conveyor belt.
[0039] In one implementation, such as Figure 17 As shown, the branch clamp assembly 210 includes a branch clamp 211, which clamps the branch pipe 02 after being closed.
[0040] The nose bridge assembly device rotates the branch tube moving component 330 to flip the uninstalled branch tube 180° to insert it into the other end of the nose bridge 01. Each branch tube 02 is arranged on the same side and in the same direction, effectively saving equipment space.
[0041] The main pipe loading device B100 includes: a first loading rack assembly 500, a main pipe loading robot 600, and a main pipe feeding robot 700; the main pipe loading robot 600 transfers the main pipe 03 to the first loading rack assembly 500, and the main pipe feeding robot 700 picks up the main pipe 03 from the first loading rack assembly 500.
[0042] like Figure 26-28 As shown, the first feeding rack assembly 500 includes: a first rack 510, an X-axis moving track 520 mounted on the first rack 510, a moving drive device 530, a support frame 540 mounted on the X-axis moving track 520 and used to support the main pipe 03, and a flattening assembly 550. The first material rack 510 can be in the form of a frame, which can serve as a support. The support frame 540 is installed on the X-direction moving track 520 by a slider. The support frame 540 is driven by the moving drive device 530 to move back and forth along the X-direction moving track 520. For example, the mobile drive device 530 can be a combination of a motor and a belt drive structure to drive the support frame 540 to move along the X-direction mobile track 520; For example, the moving drive device 530 may be a combination of a motor, gears and racks, driving the support frame 540 to move along the X-direction moving track 520; For example, the motion drive 530 can be a combination of a servo motor and a cable chain.
[0043] Furthermore, such as Figure 26-27 As shown, the support frame 540 is provided with a tray 541, and the tray 541 is provided with a plurality of upward-facing tube grooves 542; The tray 541 mainly serves a supporting function, supporting the main pipe 03. In this embodiment, since four main pipes 03 are transferred at one time, four pipe grooves 542 are provided. If the number of transmissions in main pipe 03 changes, the number of pipe slots 542 will be changed accordingly.
[0044] In this embodiment, support plates 541 are respectively provided at the front, middle and rear positions of the support frame 540, and four support plates 541 are provided to more stably support the main pipe 03.
[0045] Furthermore, the support frame 540 is provided with a flattening component 550 at both the front and rear ends; the flattening component 550 includes a driving component 551 and a flattening plate 552; the driving component 551 drives the flattening plate 552 to move in the Y direction.
[0046] For example, such as Figure 27 As shown, the driving component 551 can be a cylinder, and the output shaft of the cylinder is connected to the platen 552. Of course, the drive unit 551 can also be replaced with other drive structures that can push the platen 552 to move in the Y direction.
[0047] This device transmits four main pipes 03 at a time. The four main pipes 03 are transported synchronously to the support frame 540 by the main pipe loading robot 600. After that, they need to be processed. During the processing, the four main pipes 03 are also processed at the same time. For example, when installing a three-way valve, the three-way valve is installed on the four main pipes 03 at the same time. During the process of transferring four main pipes 03 at one time, the front ends of the four main pipes 03 may not be aligned. Some may be forward and some may be backward. The misalignment of the front ends of the four main pipes 03 will affect subsequent processing and may affect the synchronous processing of the three-way valve. Therefore, the function of the flattening component 550 is to align the front ends of the four main pipes 03. The main tube 03 is placed on the support frame 540, and the flattening components 550 at both ends of the support frame 540 operate simultaneously. The flattening plates 552 at the front and rear ends move towards each other, placing the position of the main tube 03 against the front flattening plate 552 to achieve alignment of the front end of the main tube 03.
[0048] Furthermore, such as Figure 24 and Figure 28As shown, the main feeder robot 600 includes: a second feeder 610, a Y-axis moving track 620 mounted on the second feeder 610, a suction assembly 630 mounted on the second feeder 610, and a main feeder clamp 640 mounted on the Y-axis moving track 620 and moving along the Y-axis moving track 620. Furthermore, the Y-axis moving track 620 is located above the first material rack 510, and the main material picker 640 moves along the Y-axis moving track 620 to send the main material 03 to the support frame 540. Here, the main material handling clamp 640 can be driven by a drive device to move along the Y-axis moving track 620; For example, the drive device can be a combination of a motor and a belt drive structure to drive the main feeder clamp 640 to move along the Y-direction moving track 620; For example, the drive unit may be a combination of a motor, gears and racks, driving the main feeder clamp 640 to move along the Y-direction moving track 620.
[0049] For example, the drive unit can be a combination of a servo motor and a cable chain.
[0050] like Figure 31 As shown, the main pipe clamp 640 is connected to the output shaft of the cylinder and moves in the Z direction by the cylinder to lower the main pipe 03 to the support frame 540. As described above, this application transports four main pipes 03 at a time. Therefore, the main pipe picking clamp 640 includes four clamping bodies, each clamping one main pipe 03.
[0051] Furthermore, the suction assembly 630 includes a cylinder and a suction nozzle 631, the suction nozzle 631 being driven by the cylinder to move in the Z direction; the suction nozzle 631 is connected to a vacuum device or a suction device to suck up the main pipe 03; There are also four suction nozzles 631, with one suction nozzle 631 corresponding to one clamp.
[0052] During loading, the main pipe 03 is stacked on the material platform. The suction nozzle 631 moves down and approaches the front end of the main pipe 03 under the drive. The suction nozzle 631 sucks air to lift the main pipe 03, lifting four main pipes 03 at a time. Then, when the suction nozzle 631 is performing the action of suctioning the main pipe 03, the main pipe clamp 640 is open. After the suction nozzle 631 finishes suctioning the material, the main pipe clamp 640 closes and clamps the front end of the main pipe 03. Driven by the drive device, the main pipe material picker 640 moves along the Y-direction moving track 620, dragging the main pipe 03 toward the support frame 540. After being dragged into place, the cylinder drives the main pipe material picker 640 to move down, and the main pipe material picker 640 opens to release the main pipe 03, which then moves to the support frame 540. Here, for example, the drive device can be a combination of a motor and a belt drive structure; or, the drive device can be a combination of a motor, gears and racks; or, the drive device can be a combination of a servo motor and a cable chain.
[0053] The aforementioned suction nozzle 631 is provided with four parts, the main pipe material handling clamp 640 is provided with four parts, and the pipe groove 542 is provided with four parts. The three are arranged one to one to ensure that the main pipe 03 is transported correctly.
[0054] Furthermore, the suction nozzle 631 is provided with an arc-shaped groove that matches the cross-sectional curvature of the main tube 03, so as to better suck up the main tube 03.
[0055] In one embodiment, a pressure testing device is also provided, which is connected to the suction nozzle 631; The pressure testing device is mainly used to test pressure. Assuming that all four suction nozzles 631 are adsorbed with the main pipe 03, the pressure value at each suction nozzle measured by the pressure testing device should be P, P, P, P. If one of the four suction nozzles 631 fails to properly pick up the main pipe 03, then the suction nozzle 631 is connected to the outside, and the pressure value measured by the pressure testing device at each suction nozzle may be P, P, P, or 0; this proves that the fourth suction nozzle 631 has not properly picked up the main pipe 03, and the suction nozzle 631 should move down again to pick up the main pipe 03 until the pressure value measured by the pressure testing device at each suction nozzle should be P, P, P, P; then the main pipe clamp 640 will clamp the main pipe 03 and push the main pipe 03 to move.
[0056] In one embodiment, the main feeder robot 700 includes: a third feeder 710, a first track 720 in the X direction and a second track 730 in the Y direction disposed on the third feeder 710, and a pair of picking robots 740 mounted on the second track 730; the picking robots 740 move along the first track 720 toward the first feeder assembly 500 and grab the main feeder 03 on the support frame 540.
[0057] Specifically, the height of the second track 730 is approximately the same as the height of the Y-axis moving track 620.
[0058] The material handling robot 740 is driven by one drive device to move along the first track 720 and by another drive device to move along the second track 730. For example, the drive unit can be a combination of a motor and a belt drive structure; or, the drive unit can be a combination of a motor, gears and racks; or, the drive unit can be a combination of a servo motor and a cable chain.
[0059] Furthermore, there are two picking robots 740, one picking robot 740 is close to the front end of the second track 730, and the other picking robot 740 is close to the rear end of the second track 730; like Figure 25 As shown, after the main tube 03 is placed in the support frame 540, the support frame 540 moves along the X direction, i.e., moves to the left, under the drive of the moving drive device 530. Similarly, the two picking robots 740 move along the first track 720 under the drive of the drive device, that is, move to the right; after the two picking robots 740 move to the position corresponding to the support frame 540, the two picking robots 740 move down in the Z direction to grab the main tube 03, one picking robot 740 grabs the position near the front end of the main tube 03, and the other picking robot 740 grabs the end or near the end of the main tube 03; Then, the two robotic arms 740 move synchronously along the first track 720, that is, move to the left to reset; Another picking robot 740 located at the rear end moves along the second track 730 under the drive of the drive device, moving closer to the picking robot 740 located at the front end.
[0060] It is worth noting that, such as Figure 29 As shown, the two picking robots 740 are reset, one picking robot 740 is close to the front end of the second track 730, and the other picking robot 740 is close to the rear end of the second track 730, straightening the main pipe 03. The straight distance between the front end and the rear end of the main pipe 03 is A1. like Figure 30 As shown, another picking robot 740 located at the rear end moves along the second track 730 under the drive of the drive device, and moves closer to the picking robot 740 located at the front end. After moving, the straight distance between the front end and the rear end of the main tube 03 is A2; obviously, A2 < A1. This shortens the straight-line distance between the front and back ends of the main tube 03, which can greatly save equipment volume during subsequent processing and transmission of the main tube 03. If the main tube feeding device of this application is installed on the nasal oxygen tube automatic assembly machine, the space required for continued transportation of the main tube 03 is reduced after the straight distance between the front and rear ends of the main tube 03 is shortened as described above, thus reducing the size of the equipment.
[0061] like Figure 18-19 As shown, the first transmission line group A600 includes: two first transmission belts A610 that move synchronously, a plurality of branch pipe limiting seats 400 disposed on the two first transmission belts A610, and a driving device for driving the first transmission belts A610 to rotate. Two first conveyor belts A610 are arranged side by side. The two ends of the branch pipe 02 are inserted into the branch pipe limiting seats 400 set on the two first conveyor belts A610. The branch pipe limiting seats 400 are provided with slots with upward openings. After the branch pipe 02 is inserted into the branch pipe limiting seats 400, the branch pipe limiting seats 400 have a certain clamping force on the branch pipe 02 to prevent the branch pipe 02 from falling off. The clamping positions of the branch pipe limiting seats 400 on the two first conveyor belts A610 are close to the front end and rear end of the branch pipe 02. Here, the drive unit can be a combination of a motor and gears to drive the first transmission belt A610 to rotate.
[0062] Furthermore, such as Figure 22-23 As shown, the second transmission line group B500 includes: two second transmission belts B510 that move synchronously, a plurality of main guide limit seats B520 disposed on the two second transmission belts B510, and a drive device for driving the second transmission belts B510 to rotate. Two second conveyor belts B510 are arranged side by side, and the two ends of the main pipe 03 are engaged with the main pipe limiting seats B520 provided on the two second conveyor belts B510. The main pipe limiting seats B520 are provided with upward-facing slots. After the main pipe 03 is engaged with the main pipe limiting seats B520, the main pipe limiting seats B520 exert a certain clamping force on the main pipe 03 to prevent the main pipe 03 from falling off. The clamping positions of the main pipe limiting seats B520 on the two second conveyor belts B510 are close to the front and rear ends of the main pipe 03. Here, the drive unit can be a combination of a motor and gears to drive the first transmission belt A610 to rotate.
[0063] like Figure 1 and Figure 4 As shown, the branch pipe feeding device A100 includes: branch pipe storage bin A110, branch pipe feeding rack A120, first branch pipe feeding robot A130 and second branch pipe feeding robot A140; The first branch pipe loading robot A130 and the first branch pipe loading robot A140 are mounted on a Y-axis track. The branch pipe loading rack A120 is equipped with multiple trays, and each tray has several pipe slots. Here, the number of pipe slots is limited to eight. The first branch pipe loading robot A130 takes eight branch pipes 02 from the branch pipe storage bin A110 at once and places them on the branch pipe loading rack A120, where they are supported by the pipe slots. The second branch pipe loading robot A140 delivers the branch pipes 02 from the branch pipe loading rack A120 to the first transmission line group A600 and supports them on the branch pipe limiting seat 400. Figure 5 As shown, eight branch pipes 02 of one group have been placed on the first transmission line group A600 and are waiting to transmit for switching workstations.
[0064] For example, referring to the structure of the main pipe feeding device B100, the branch pipe feeding rack A120 of the branch pipe feeding device A100 may also have a flattening component A150, which flattens and aligns the eight branch pipes 02 to facilitate the subsequent installation of the fixing ring 04 and nose bracket 01.
[0065] like Figure 3 As shown, the first assembly line A1 is also equipped with a paralleling robot A160. The paralleling robot A160 has a pneumatic clamp and can move in the X and Z directions. The paralleling robot A160 merges the ends of the eight branch pipes 02, and after merging, as shown... Figure 5 As shown, the front ends of the eight branch tubes 02 are separate, while the rear ends of the eight branch tubes 02 are joined together in pairs, which facilitates the subsequent installation of a fixing ring 04 at the rear end of the branch tubes 02 and a nose bridge 01 at the front end of the branch tubes 02.
[0066] like Figure 8 As shown, the fixed ring assembly device A200 includes: a fixed ring vibratory plate A210, a fixed ring material rail A220, a fixed ring feeding robot A230, and a clamping assembly A240. The four sets of branch pipes after being combined are clamped in the clamping assembly A240. The fixed ring vibratory plate A210 transmits the fixed ring 04 at the correct angle. After transmission, the fixed ring 04 is clamped by the fixed ring feeding robot A230. Finally, the fixed ring 04 is inserted into the end of the branch pipe 02. like Figure 7 As shown, it also includes a pushing device A250, which is used to further push the fixing ring 04 towards the front end of the branch pipe 02. The pushing device A250 has a pushing plate A251, and the top of the pushing plate A251 is provided with a slot A252, through which the branch pipe 02 can pass. Since the diameter of the fixing ring 04 is larger than the inner diameter of the slot, when the pushing plate A251 moves in the Y direction, it pushes the fixing ring 04 towards the front end of the branch pipe 02.
[0067] like Figure 1-2 As shown, a three-way valve assembly device A300 is also provided on the side of the feeding device A250. The three-way valve assembly device A300 adopts the existing technology. The main feature is that after the fixing ring 04 is installed, the three-way pipe is installed at the end of the branch pipe 02. The third interface of the three-way pipe is then connected to the main pipe 03. Furthermore, an adhesive applicator A310 can be installed before the three-way valve assembly device A300. The adhesive applicator A310 uses existing technology to apply adhesive to the end of the branch pipe 02. After applying the adhesive, the three-way valve is installed so that the branch pipe 02 and the three-way valve are glued and fixed together.
[0068] like Figure 10-11As shown, the nose support feeding device A400 includes: a nose support vibrating plate A410, a nose support material rail A420, and a nose support picking robot A430. The nose support picking robot A430 clamps the nose support 01 and inserts it into one end of a branch pipe 02.
[0069] Subsequently, the branch tube containing the nose clip 01 is transmitted to the next station, namely the nose clip assembly device A500, via the first transmission line group A600. In the nose clip assembly device A500, another branch tube 02 is bent and inserted into the other end of the nose clip 01, thus completing the assembly of the nose clip 01.
[0070] like Figure 20 As shown, the material handling robot 740 feeds the main pipe 03 into the second transmission line group B500 and locks it in the main pipe limit seat B520. like Figure 32 As shown, the handling robot C1 includes: The transport bracket C100 is equipped with a first guide rail C200 in the Y direction; The first handling arm C300 is mounted on the first guide rail C200 and is provided with a first pin assembly C310, a first gripper C320 and a second gripper C330; The second handling arm C400 is mounted on the first guide rail C200 and is equipped with a third clamping component C410 and a fourth clamping component C420. The second assembly line B1 is equipped with a clamping assembly B600 corresponding to the second handling arm C400.
[0071] In use, the first handling arm C300 grabs the semi-finished product that has been installed on the first transmission line group A600, and the first handling arm C300 moves along the first guide rail C200 to move the semi-finished product to the second transmission line group B500. The second handling arm C400 clamps the semi-finished product. A clamping component is also provided on the second assembly line B1 to clamp the front end of the main pipe 03. Then, the second handling arm C400 aligns the three-way valve in the semi-finished product with the front end of the main pipe 03 and inserts the front end of the main pipe 03 into the three-way valve.
[0072] like Figure 2 As shown, the horn connector feeding device B200 is used to install horn connectors at the end of the main pipe 03. The horn connector feeding device B200 adopts existing technology, which will not be described in detail here.
[0073] For example, adhesive needs to be applied before the nose bracket 01 is installed at the front end of the branch pipe 02, before the three-way valve is installed at the front end of the main pipe 03, and before the horn connector is installed at the end of the main pipe 03. Therefore, adhesive application devices are set before these work stations to apply adhesive to the ends of the branch pipe 02 and the main pipe 03. After applying adhesive, the corresponding nose bracket 01 and three-way valve are glued and fixed.
[0074] The adhesive application device used here is based on existing technology, and its specific structure and function will not be described in detail.
[0075] For example, the second assembly line B1 is also provided with a drying device B400, such as Figure 21 As shown, the drying device B400 can be multiple fans and heating elements to achieve hot air drying; the drying device B400 corresponds to the front end of the branch pipe 02, the front end of the main pipe 03, and the rear end of the main pipe 03 to hot air dry and fix each adhesive fixing point.
[0076] For example, the second assembly line B1 may also be equipped with a detection device to detect whether the nasal oxygen tube is blocked or leaking.
[0077] The specific assembly process of the fully automatic nasal oxygen cannula assembly machine of this invention is as follows: Branch pipe feeding---branch pipe connection---install fixing ring---install three-way valve---install nose bracket---main pipe feeding---semi-finished product handling---main pipe installation of three-way valve and branch pipe connection---install horn connector---plug and leak detection---hot air drying---check for air leaks---unloading; It can assemble nasal oxygen cannulas fully automatically, resulting in high production efficiency.
[0078] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the scope of the present invention are still within the scope of the present invention.
