Detailed Implementation

[0067] 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.

[0068] Please see Figures 1 to 6 As shown, a small hose feeding mechanism includes a frame 1, a small hose feeding device 2, a small hose positioning device 3, a small hose feeding device 4, and several sets of carriers 6 arranged on a transmission device 5. The small hose positioning device 3 includes a support platform 7, a limiting component 8 arranged on the support platform 7 for positioning the small hose, and a closing device 9 for bringing together one end of two small hoses on the limiting component 8. The small hose feeding device 4 is movably arranged between the small hose positioning device 3 and the carriers 6.

[0069] The small hose feeding device 2 feeds the small hoses to the small hose positioning device 3. The small hose positioning device 3 includes a closing device 9, which adjusts two parallel small hoses so that one end is closed and the other end remains open. Then, the small hose loading device 4 picks up the small hose in this state and loads it onto the carrier 6 for subsequent processing. This invention has a reasonable structure and ingenious design, enabling precise loading of small hoses during processing.

[0070] Specifically, the small hose feeding device 2 includes a material box 10, a material picking component 11, and a feeding drive 12 connected to the material picking component 11. The material picking component 11 is used to pick up the small hose in the material box 10 and can move the small hose to the small hose positioning device 3 under the drive of the feeding drive 12.

[0071] like Figure 2 As shown, the material box 10 is used to store small hoses. In order to ensure that the material picking component 11 can accurately pick up the small hoses when it descends the same distance, the bottom plate 13 of the material box 10 is movably set inside the material box 10. The bottom plate 13 is provided with a top material drive 14. After the top layer of small hoses is picked up, the bottom plate 13 can rise along the inner side wall of the material box 10 under the drive of the top material drive 14, raising the small hoses in the material box 10 as a whole a certain distance.

[0072] In this embodiment, there can be two or more material bins 10, which are slidably mounted on the material rack 16 via a base 15, and the material transfer drive is connected to the base 15. Multiple material bins 10 provide sufficient material supply to the small hose, and the material transfer drive is used to switch between multiple material bins 10 at the material pickup assembly 11.

[0073] The material picking assembly 11 preferably consists of two negative pressure suction heads arranged side by side, which pick up two small hoses from the material box 10 at a time. The negative pressure suction head is equipped with a detection probe for detecting whether the negative pressure suction head has picked up the small hose. When the detection probe detects that there is no small hose at the negative pressure suction head after a suction action, the negative pressure suction head repeats the suction once until both negative pressure suction heads have picked up the small hose. Then, the material feeding drive 12 drives the two small hoses to move to the small hose positioning device 3.

[0074] like Figure 3 As shown, the small hose positioning device 3 includes a support platform 7, a limiting component 8 disposed on the support platform 7 to position the small hose, and a closing device 9 for bringing together one end of two small hoses on the limiting component 8. The support platform 7 is provided with adjustment drives 17 at both ends, and the output end of the adjustment drive 17 is equipped with an adjustment block 18 for aligning the ends of the small hoses.

[0075] Limiting component 8 is used to support the loaded small flexible tube, such as Figure 4 As shown, the limiting assembly 8 includes several fixed limiting members 19, lifting limiting members 20, and a lifting drive 21 connected to the lifting limiting members 20. The fixed limiting members 19 can be limiting grooves or V-shaped long grooves provided on the support platform 7. The lifting limiting members 20 are located near the closing device 9. When the closing device 9 is working, the lifting drive 21 drives the lifting limiting members 20 to descend, avoiding interference with the closing device 9.

[0076] The closing device 9 includes a first limiting block 22 and a second limiting block 23 arranged opposite to each other, and a closing drive 24. The first limiting block 22 and the second limiting block 23 are movably arranged on the support platform 7 and can be brought together by the closing drive 24.

[0077] The feeding drive 12 loads two small hoses onto the limiting component 8. The fixed limiting component 19 and the lifting limiting component 20 support the small hoses from multiple positions. The adjusting block 18 adjusts the distance between the two ends of the two small hoses under the drive of the adjusting drive 17. Then, the lifting limiting component 20 descends, and the closing device 9 drives one end of the two small hoses to come together, forming a closed state at one end.

[0078] like Figure 5 As shown, the small hose feeding device 4 includes at least a first feeding robot 25 and a second feeding robot 26. The first feeding robot 25 is used to grab the small hose at the closing device 9. The second feeding robot 26 has two spaced feeding claws for grabbing two hoses that are separated at the other end.

[0079] like Figure 6As shown, the carrier 6 is mounted on the transmission device 5. The carrier 6 includes two positioning blocks 27 arranged opposite to each other. One positioning block 27 is provided with a first slot 28. The first loading robot 25 grabs the small hose at the closing device 9 and merges the two close-to-close small hoses into the first slot 28. The other positioning block 27 is provided with two second slots 29. The two loading claws of the second loading robot 26 grab the small hoses respectively and clamp the two small hoses into the second slots 29 respectively.

[0080] Furthermore, a partition 30 is provided in the first slot 28 to separate the small flexible tubes that are close to each other in the first slot 28, so as to facilitate the subsequent assembly of the adjustment buckle.

[0081] Please see Figure 7-13 This embodiment provides a technical solution: a nasal plug assembly mechanism, including a nasal plug feeding device 101, a glue applicator 104 for applying glue to a small flexible tube on a carrier 6 on a transmission device 5, and a cannula device 105 for inserting the end of the glued small flexible tube into both ends of the nasal plug. The nasal plug feeding device 101 includes a first vibrating plate 106, a receiving pipe 107, a receiving tray 108, and a clamping device 109 for clamping the nasal plug on the receiving tray 108 onto the carrier 6. The output end of the first vibrating plate 106 is connected to the receiving pipe 107, and the output end of the receiving pipe 107 is connected to the receiving tray 108. A first support frame 110 is fixed below the receiving tray 108, and an adjustment device 111 for adjusting the height of the receiving pipe 107 is provided below the receiving pipe 107.

[0082] The clamping device 109 includes a base 112, a second support frame 113, a first gripper cylinder 114, a first Y-axis cylinder 115, a first Z-axis cylinder 116, and a first rotating motor 117. The base 112 is fixed on the frame, and the first support frame 110 and the second support frame 113 are both fixed on it. The first Y-axis cylinder 115 is fixed on the second support frame 113. The first Z-axis cylinder 116 is fixed on the output end of the first Y-axis cylinder 115. The first rotating motor 117 is fixed on the output end of the first Z-axis cylinder 116. The first gripper cylinder 114 is fixed on the output end of the first rotating motor 117.

[0083] Under the force of vibration, the nose plug inside the first vibratory plate 106 gradually moves into the receiving pipe 107 and then gradually pushes into the receiving plate 108. The position of the first gripper cylinder 114 can be adjusted by the first Y-axis cylinder 115 and the first Z-axis cylinder 116. Under the gripping action of the first gripper cylinder 114, the nose plug in the receiving plate 108 is moved to the carrier 6 on the transmission device 5.

[0084] The first transfer motor 117 can rotate the nose plug 1090 degrees before placing it on the carrier 6, which facilitates subsequent processing.

[0085] In this embodiment, the clamping device 109 further includes a first detection device 118 for detecting whether the nasal plug has reached the position of the receiving tray 108. The first detection device 118 can detect in real time whether there is a nasal plug in the receiving tray 108, so as to facilitate clamping it.

[0086] Furthermore, the adjusting device 111 includes a support base 119 and a lead screw 120. The bottom of the receiving pipe 107 is fixed on the support base 119. The four corners of the support base 119 are threadedly connected to the lead screw 120. The bottom end of the lead screw 120 is rotatably connected to the base 112. By rotating the lead screw 120, the height of the receiving channel can be adjusted so that it can be easily aligned with the output end of the first vibrating plate 106.

[0087] Please see Figure 11 The difference between this embodiment and Embodiment 1 is that the glue applicator 104 includes a third support frame 121, a fourth support frame 122, a first glue container 123, a second Y-axis cylinder 124, a second Z-axis cylinder 125, a second gripper cylinder 126, and a pressing component 127. The third support frame 121 and the fourth support frame 122 are both fixed on the machine frame. The second Y-axis cylinder 124 is fixed on the third support frame 121. The second Z-axis cylinder 125 is fixed on the output end of the second Y-axis cylinder 124. Two second gripper cylinders 126 are fixed on the output end of the second Z-axis cylinder 125, corresponding to the two small hoses on the carrier 6 respectively. The pressing component 127 is fixed on the third support frame 121 and is used to press down and fix the small hoses on the carrier 6. The first glue container 123 is set on the fourth support frame 122.

[0088] During operation, glue is added to the first glue container 123 beforehand. Two second gripper cylinders 126 clamp the two small hoses on the carrier 6 respectively, and the small hoses are inserted into the first glue container 123 containing glue by the second Y-axis cylinder 124 and the second Z-axis cylinder 125, thus achieving the glue application to the small hoses. The pressing assembly 127 includes a pressing cylinder 128 and a pressing block 129. The pressing cylinder 128 is fixed on the third support frame 121, and the pressing block 129 is fixed to the output end of the pressing cylinder 128. The pressing block 129 can fix the small hoses during the glue application process.

[0089] Please see Figure 12The difference between this embodiment and the combination of Embodiments 1 and 2 is that the insertion device 105 includes a fifth support frame 130, a third Z-axis cylinder 131, an X-axis bidirectional cylinder 132, and an insertion assembly 133. The fifth support frame 130 is fixed on the machine frame, the third Z-axis cylinder 131 is fixed on the fifth support frame 130, the X-axis bidirectional cylinder 132 is fixed on the output end of the third Z-axis cylinder 131, and there are two insertion assemblies 133, which are respectively fixed on the two output ends of the X-axis bidirectional cylinder 132. The insertion assembly 133 includes a third Y-axis cylinder 138, a second material transfer motor 139, and a third gripper cylinder 1040. The two third Y-axis cylinders 138 on the two insertion assemblies 133 are respectively fixed on the output ends of the X-axis bidirectional cylinder 132, the second material transfer motor 139 is fixed on the output end of the third Y-axis cylinder 138, and the third gripper cylinder 1040 is fixed on the output end of the second material transfer motor 139.

[0090] When inserting the glued small tubing into the nasal plug, two third-claw cylinders 1040 can respectively clamp the two glued small tubing. By rotating the second transfer cylinder, the end of the small tubing can be rotated 1090 degrees. The end of the small tubing can be aligned with the holes at both ends of the nasal plug by the third Z-axis cylinder 131 and the third Y-axis cylinder 138. Then, the X-axis bidirectional cylinder 132 drives the two small tubing to move towards each other and insert them into the nasal plug.
