Description

Technical Field

[0001] This invention belongs to the field of medical device technology and relates to a rotary catheter external adhesive filling mechanism. Background Technology

[0002] The assembly of medical catheters and connectors is generally done by gluing. To reduce bacterial infection and speed up assembly, automated gluing is usually performed using mechanical equipment. For example, a Chinese patent discloses a medical catheter gluing device (application number 201610580492.5), which includes: a gluing mechanism, a gluing holding mechanism, and a frame. The gluing mechanism picks up gluing from the gluing holding mechanism placed on the frame. The upper end of the frame is provided with a gluing transfer mechanism that drives the gluing mechanism to rotate. The gluing mechanism includes: a plurality of gripping fingers and a gripping finger drive source that drives the gripping fingers to open and close. The rear end of the gripping finger drive source is connected to a rotating wheel of the gluing transfer mechanism. The rotating wheel drives the gripping finger drive source to rotate under the drive of the rotating drive source. The rotating drive source is connected to the frame.

[0003] This device for applying adhesive to the outer surface of a conduit has the following drawbacks: 1. The gripper fingers need to first grip the adhesive rod coated with adhesive, and then grip and rotate the conduit to apply the adhesive. This method of applying adhesive by using the gripper fingers to transfer the adhesive is prone to insufficient adhesive application, resulting in limited application effectiveness. 2. Due to the presence of the lifting adhesive rod, gripper fingers, and gripper finger drive source, it occupies a large space. The adhesive application process often requires a separate workstation. After the conduit is coated with adhesive, it is moved to the next workstation for assembly with other components. This makes the overall assembly equipment large in size and costly, and there is also a risk that assembly will not be possible after adhesive application. 3. To facilitate the application of adhesive from the upper and lower parts of the adhesive rod, the adhesive holding mechanism needs to be open. The adhesive is volatile and toxic, and long-term operation may affect the health of employees. Given the above-mentioned drawbacks of the existing technology, it is necessary to conduct research to solve these problems. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide a reliable and compact rotary conduit external adhesive filling mechanism.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows.

[0006] A rotary external adhesive filling mechanism for a conduit includes an adhesive storage box, an adhesive filling box, adhesive filling components, a rotating assembly, and a rotating drive. The adhesive storage box is connected to the adhesive filling box via a connecting connector and supplies adhesive to the adhesive filling box. The adhesive filling box is located in front of the rotating assembly. Several adhesive filling components are arranged side by side and spaced apart inside the adhesive filling box. The rotating assembly includes a rotating shaft with its front end passing through the adhesive filling box. The adhesive filling components are fixed to the front end of the rotating shaft. The rotating drive is connected to the rotating shaft and drives the rotating shaft and the adhesive filling components to rotate synchronously.

[0007] The glue-filling component includes a glue-filling head, which includes a glue-filling disc and a glue-filling head connecting part. The glue-filling disc is disc-shaped with a through-hole in the middle. Multiple radially penetrating glue-filling channels are provided between the outer wall of the glue-filling disc and the peripheral wall of the inlet. The glue-filling head connecting part is fixedly connected to the front end of the rotating shaft.

[0008] The glue-filling head is driven by a rotating shaft to make a circular motion, which can evenly transfer the glue in the glue-filling box into the glue-inlet channel. When the end of the guide tube is inserted into the inlet, a glue film is formed on the outer wall of the guide tube to achieve the effect of glue filling outside the guide tube.

[0009] Furthermore, the adhesive filling component also includes a limiting rod, which is cylindrical with a limiting head at its head. The limiting head is conical and is used to extend into the conduit port to block the conduit opening and prevent adhesive from entering the conduit. The limiting rod is inserted into the front end of the rotating shaft and tightly connected to it. When the limiting rod is installed, its limiting head faces the inlet and is arranged coaxially with the inlet.

[0010] Furthermore, the glue head connector is a cylindrical structure extending rearward from the center of the glue filling disc, with an outer diameter smaller than that of the glue filling disc, and is arranged coaxially with the glue filling disc; the glue head connector is provided with a first groove and a second groove from front to back, both of which are U-shaped grooves with openings facing upwards, wherein the depth and width of the second groove are greater than those of the first groove, and the front end of the second groove forms a glue filling head limiting step; the first groove is axially connected to the inlet and the second groove, and the bottom end of the first groove is located below the inlet; the front end of the rotating shaft is fixedly connected to the groove wall of the second groove, and the limiting head is accommodated in the first groove.

[0011] Furthermore, the first groove has several glue flow holes on its wall, and the second groove has a through glue head mounting hole at its bottom, wherein the glue head mounting hole is elongated.

[0012] Furthermore, a limiting ring extends outward from the outer side of the limiting head. The outer diameter of the limiting ring is larger than the outer diameter of the limiting rod body and matches the groove width of the first groove. The limiting ring can be accommodated at the bottom of the first groove. The inner diameter of the limiting ring is smaller than the outer diameter of the limiting rod body, but larger than the outer diameter of the limiting head. There is a gap between the limiting ring and the limiting head for the insertion of the conduit port.

[0013] Furthermore, several forward-facing glue-flowing grooves are spaced apart on the peripheral wall of the limiting ring.

[0014] Furthermore, the glue storage box includes a box body, a glue float, a glue level sensor, and a box cover. A partition is located in the middle of the box body, dividing it into a glue inlet area and a ball-stabilizing area arranged front and rear. A glue outlet is located at the bottom of the partition, connecting the glue inlet area and the ball-stabilizing area. A glue inlet is located on the side wall of the glue inlet area, connected to a pressure-retaining mechanism. A glue outlet is located on the side wall of the ball-stabilizing area opposite the glue tank. A glue float is built into the ball-stabilizing area, with a float detection head fixed to its bottom. A glue level sensor is inserted into the bottom of the box body, with the float detection head positioned above the sensor. Float positioning protrusions are located on all four walls of the ball-stabilizing area to limit the rising and falling trajectory of the glue float. A cover is also placed on the box body, allowing the glue to flow within a relatively enclosed space.

[0015] Furthermore, the glue filling box includes a glue tank and a glue tank cover. Glue filling detection ports and glue filling inlets are respectively provided at the same height on the left and right side walls of the glue tank. The glue filling inlet is horizontally opposite to the glue outlet of the glue storage box, and the two ports are connected by a connecting connector. Several glue filling ports are provided on the front of the glue tank, with guide flares facing outwards. Several rotating connection ports are provided on the back of the glue tank, with the number of rotating connection ports, glue filling ports, and glue filling parts corresponding to each other. A glue filling detection port is connected to a glue filling tank detection connector.

[0016] Furthermore, the rotating assembly includes several rotating shafts and a first support plate and a second support plate arranged front to back and fixed on a fixed base plate. The first support plate is located behind the glue tank. The rotating shafts are spaced apart and pass through the first support plate and the second support plate. The front part of the rotating shaft passes through the rotating connection port of the glue filling box and is placed inside the glue filling box. A glue plug is also fitted between the rotating connection port and the rotating shaft. The glue plug is fixed to the back of the glue tank. The glue plug is ring-shaped and the rotating shaft can rotate along the inner wall of the glue plug. A first bearing is fitted between the rotating shaft and the first support plate, and a second bearing is fitted between the rotating shaft and the second support plate. A cylindrical gear is also fitted in the middle and rear part of the rotating shaft. The cylindrical gear is located between the first support plate and the second support plate. A pinion meshes between two adjacent cylindrical gears. A synchronous pulley is also fixedly connected to the tail end of a certain rotating shaft. The synchronous pulley is connected to the rotating drive component. When the rotating drive component drives the synchronous pulley to rotate, it drives the rotating shaft connected to the synchronous pulley to rotate, which in turn drives the cylindrical gear on the rotating shaft to rotate, and then drives the pinion and other rotating shafts to rotate synchronously.

[0017] Furthermore, the front end of the rotating shaft has an inwardly facing insertion groove, into which the limiting rod is inserted; the outer wall of the rotating shaft consists of a first adapter, a second adapter, a third adapter, a fourth adapter, and a fifth adapter from front to back. The first adapter is used to connect with the glue head connection part of the glue-filling component. The first adapter is housed in the groove of the second recess. The outer wall of the first adapter has a rotating shaft mounting hole. The glue-filling head is fixedly connected to the rotating shaft by passing a positioning pin through the glue head mounting hole and the rotating shaft mounting hole. The second adapter is used to fit the glue plug. An annular groove is also provided between the first adapter and the second adapter. The third adapter is used to fit the first bearing. The fourth adapter is used to fit the cylindrical gear. A limiting notch is provided on the peripheral wall of the fourth adapter. The fifth adapter is used to fit the second bearing.

[0018] Compared with existing technologies, this rotary external adhesive filling mechanism for conduits allows adhesive to flow from a storage box to a filling box, with real-time monitoring of the adhesive level to ensure adequate filling of the conduit. The filling disc contacts the adhesive, and the rotation of the filling head evenly distributes the adhesive from the filling box into the inlet channel. When the end of the conduit is inserted into the inlet, an adhesive film forms on the outer wall of the conduit, achieving the external adhesive filling effect. The filling process is simpler; apart from providing kinetic energy to the rotating shaft, only the conduit needs to move in and out of the filling component to complete the external adhesive filling. The filling process does not require an additional robotic arm, and the relatively enclosed working environment minimizes the volatile odor of the adhesive, greatly improving the working environment.

[0019] In this invention, the glue storage, glue holding and glue addition are integrated into one design, making the structure more compact and unobstructed from the front, back and top. It can be placed between the conduit conveying line and the material outlet of the connector to be assembled. The conduit completes the glue addition and assembly work at the same station. The overall equipment can reduce the station space required for the original glue addition. The structure of the entire assembly equipment is also simpler, more compact and efficient, and the cost can be reduced and controlled. Attached Figure Description

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0035] Conversely, this invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of the invention as defined in the claims. Furthermore, to provide a better understanding of the invention, certain specific details are described in detail below. However, those skilled in the art will fully understand the invention even without these detailed descriptions.

[0036] like Figure 1-13As shown, this embodiment provides a rotary external glue-filling mechanism, including a glue storage box 1, a glue-filling box 2, a glue-filling component 3, a rotating assembly 4, a rotating drive component 5, and a glue valve 6. Glue is pressurized from the pressure-retaining mechanism into the glue storage box 1 via a corrosion-resistant solenoid valve. The glue storage box 1 and the glue-filling box 2 are connected by a connecting joint 7, which is a hollow tubular structure, ensuring that the glue level in the glue storage box 1 is level with the glue level in the glue-filling box 2. This also ensures that the glue input into the glue-filling box 2 is carried out under relatively sealed conditions. The glue-filling box 2 and the rotating assembly 4 are arranged front to back and fixed on a fixed base plate 9. The glue-filling component 3 is fixed to the front end of the rotating shaft 41 of the rotating assembly 4 and is driven by the rotating drive component 5 to rotate synchronously with the rotating shaft 41.

[0037] like Figure 1-5 As shown, the glue storage box 1 includes a glue storage box body 11, a glue float 12, a glue level sensor 13, and a glue storage box cover 14. A partition 111 is provided in the middle of the glue storage box body 11, dividing the glue storage box body 11 into a glue inlet area 112 and a ball stabilizing area 113 arranged front and rear. A glue outlet 114 is provided at the bottom of the partition 111 to connect the glue inlet area 112 and the ball stabilizing area 113. A glue inlet 115 is provided on the side wall of the glue inlet area 112, which is connected to the "pressure holding mechanism". A glue outlet 116 is provided on the side wall of the ball stabilizing area 113 opposite to the glue tank 2. A glue float 12 is installed, with a float detection head 131 fixed to its bottom. A glue level sensor 13 is inserted into the bottom of the glue storage box 11, with the float detection head 131 positioned above the glue level sensor 13. This ensures that there is sufficient space between the bottom of the glue float 12 and the bottom surface of the glue storage box 11, guaranteeing a minimum glue level to ensure the glue supply in the glue tank 2, while also monitoring the glue level in the glue storage box 1. When the float detection head 131 at the bottom of the glue float 12 contacts the glue level sensor 13, the glue valve 5 is activated, pressing the glue from the "pressure release mechanism" into the glue storage box 1. Float positioning protrusions 117 are provided on all four walls of the stabilizing area 113 to limit the rising and falling trajectory of the glue float 12, ensuring that the float detection head 131 at the bottom of the glue float 12 is aligned with the glue level sensor 13, resulting in stable and accurate sensing. The glue storage box 11 is also covered with a cover plate 14, which allows the glue to flow in a relatively enclosed space, effectively reducing the evaporation of the glue.

[0038] The glue storage box 1 contains a glue float 12 and a level sensor 13 to monitor the glue level in the storage box 1 in real time. The glue storage box 1 and the glue filling box 2 are connected by a hollow connector to ensure that the glue level in the storage box 1 is the same as that in the filling box 2. By setting up the glue storage box 1 and monitoring the glue level in real time, automated glue feeding of the storage box 1 can be achieved, while simultaneously ensuring automated glue feeding of the filling box 2, thus improving the overall automation level of the mechanism.

[0039] like Figure 1 , 6 As shown in Figures 7 and 8, the glue filling box 2 includes a glue tank 21 and a glue tank cover 22, and multiple glue filling parts 3 are arranged side by side in the glue tank 21.

[0040] The glue tank 21 has glue detection ports 212 and glue inlets 211 on its left and right side walls, respectively. The glue detection ports 212 and glue inlets 211 are set at the same height to facilitate real-time monitoring of the glue level in the glue filling box 2 and the glue storage box 1. The glue inlet 211 is horizontally aligned with the glue outlet 116 of the glue storage box 1, and the two are connected by a connecting connector 7. The front of the glue tank 21 has several glue filling ports 213, each with an outward-facing guide flare. The back of the glue tank 21 has several rotating connection ports 214, with the number of rotating connection ports 214, glue filling ports 213, and glue-filling components 3 corresponding to each other. The glue tank 21 has a glue addition observation port 215 on its side wall, above the glue addition detection port 212. The bottom of the observation port 215 is flush with the bottom of the rotary connection port 214. This prevents the glue level from exceeding the bottom of the rotary connection port 214, further preventing glue overflow. The observation port 215 is a vent, as the glue tank 21 cannot be completely sealed. It also serves as a warning of the maximum glue level; exceeding this level will cause glue to overflow from this port.

[0041] The glue filling detection port 212 is connected to a glue filling tank detection connector 217 to further monitor the glue quantity in the glue filling box 2. The bottom of the glue filling tank detection connector 217 is connected to a side right-angle connector 216. The side right-angle connector 216 is directly connected to the glue holding mechanism through a glue tube, so that the glue in the glue storage box 1 and the glue filling box 2 achieve a balance between inflow and outflow. The bottom of the glue tank 21 is also provided with a glue filling outlet, which is connected to a bottom right-angle connector 218 to drain residual glue when work is stopped. During operation, the right-angle connector 216 at this location can also block the glue filling outlet to prevent glue leakage.

[0042] like Figure 7-11 As shown, the glue-filling component 3 includes a glue-filling head 31 and a limiting rod 32 from front to back.

[0043] The glue-filling head 31 includes a glue-filling disc 311 and a glue-filling head connector 312. The glue-filling disc 311 is disc-shaped, with a through-hole 313 in its center. Multiple radially penetrating glue-filling channels 314 are provided between the outer wall of the glue-filling disc 311 and the peripheral wall of the through-hole 313. The glue-filling channels 314 are evenly spaced circumferentially. When the glue-filling head 31 is installed, its bottom height is between the upper and lower ends of the glue-filling inlet 211, ensuring that the bottom surface of the glue-filling disc 311 can contact the glue.

[0044] The glue head connector 312 is a cylindrical structure extending rearward from the center of the glue filling disc 311. Its outer diameter is smaller than that of the glue filling disc 311, and it is arranged coaxially with the glue filling disc 311. From front to back, the glue head connector 312 has a first groove 315 and a second groove 316. Both the first groove 315 and the second groove 316 are U-shaped grooves with upward openings. The depth and width of the second groove 316 are greater than those of the first groove 315 (the top of the first groove 315 is higher than the top of the second groove 316). The front end of the second groove 316 forms a glue filling head limiting step 317. The first groove 315 is axially connected to the inlet 313 and the second groove 316. The bottom end of the first groove 315 is located below the inlet 313. The first groove 315 has several glue flow holes 318 on its groove wall, and excess glue in the inlet 313 can flow out through the glue flow holes 318. The bottom of the second groove 316 has a through glue head mounting hole 319.

[0045] The limiting rod 32 is cylindrical, with a limiting head 321 at its head. The limiting head 321 is conical and is used to extend into the conduit port to block the conduit opening and prevent glue from entering the conduit, while also effectively limiting the length of glue application in the conduit. When the limiting rod 32 is installed, its limiting head 321 faces the inlet 313 and is coaxially arranged with the inlet 313. A limiting ring 322 extends outward from the outer side of the limiting head 321. The outer diameter of the limiting ring 322 is larger than the outer diameter of the limiting rod 32 and matches the groove width of the first groove 315. The limiting ring 322 can be accommodated at the bottom of the first groove 315. The inner diameter of the limiting ring 322 is smaller than the outer diameter of the limiting rod 32 but larger than the outer diameter of the limiting head 321, creating a gap between the limiting ring 322 and the limiting head 321 for the conduit port to insert into. The limiting head 321 protrudes axially from the limiting ring 322. Several adhesive flow channels 323 with forward-facing openings are provided at intervals on the periphery of the limiting ring 322 to prevent adhesive from accumulating inside the limiting ring 322, and the adhesive can be thrown out from the adhesive flow channels 323.

[0046] like Figure 7 , 12 As shown in Figure 13, the rotating assembly 4 includes several rotating shafts 41 and a first support plate 42 and a second support plate 43 arranged in front and behind the fixed base plate 9. The first support plate 42 is located behind the glue tank 21. The rotating shafts 41 are spaced through the first support plate 42 and the second support plate 43. The front part of the rotating shaft 41 passes through the rotating connection port 214 of the glue filling box 2 and is placed inside the glue filling box 2. A glue plug 8 is also provided between the rotating connection port 214 and the rotating shaft 41 to prevent glue from leaking from the rotating connection port 214. The glue plug 8 is fixed on the back of the glue filling box 2. The glue plug 8 is ring-shaped and the rotating shaft 41 can rotate along the inner wall of the glue plug 8.

[0047] A first bearing 44 is fitted between the rotating shaft 41 and the first support plate 42, and a second bearing 45 is fitted between the rotating shaft 41 and the second support plate 43, allowing the rotating shaft 41 to rotate stably and smoothly on the first support plate 42 and the second support plate 43. A cylindrical gear 46 is also fitted in the middle and rear part of the rotating shaft 41, located between the first support plate 42 and the second support plate 43. A pinion 47 meshes between adjacent cylindrical gears 46. A synchronous pulley 48 is also fixedly connected to the tail end of one of the rotating shafts 41. When the synchronous pulley 48 is rotated, it drives the rotating shaft 41 connected to the synchronous pulley 48 to rotate, which in turn drives the cylindrical gear 46 on the rotating shaft 41 to rotate, and then drives the pinion 47 and other rotating shafts 41 to rotate synchronously. A dust cover 49 is also connected to the upper end face and side face of the first support plate 42 and the second support plate 43.

[0048] The adhesive-filled part 3 is fixed to the front of the rotating shaft 41 and rotates synchronously with it. Specifically, the front end of the rotating shaft 41 is provided with an insertion groove 411, and the limiting rod 32 is inserted into the insertion groove 411 at the front end of the rotating shaft 41. The limiting rod 32 is tightly connected to the rotating shaft 41. The outer bottom end of the limiting ring 322 of the limiting rod 32 is used to limit the maximum insertion depth of the limiting rod 32.

[0049] The outer wall of the rotating shaft 41 consists of a first adapter 412, a second adapter 413, a third adapter 414, a fourth adapter 415, and a fifth adapter 416, arranged from front to back. The first adapter 412 connects to the glue head connection 312 of the filling component 3. The first adapter 412 is housed within the groove of the second recess 316. A rotating shaft mounting hole 4121 is provided on the outer wall of the first adapter 412. A positioning pin (not shown in the figure) passes through the glue head mounting hole 319 and the rotating shaft mounting hole 4121 to fix the filling head 31 to the rotating shaft 41. The glue head mounting hole 319 is elongated, allowing for adjustment of the installation position (depth) of the filling head 31. Simultaneously, the insertion depth of the limiting rod 32 can also be finely adjusted, making the installation of the filling component 3 more flexible and adaptable to conduits with different filling length requirements. The glue-filling head limiting step 317 limits the maximum installation depth of the glue-filling head 31, which is when the front end of the first adapter 412 abuts against the glue-filling head limiting step 317.

[0050] The second adapter 413 is used to fit the rubber plug 8. An annular groove 417 is also provided between the first adapter 412 and the second adapter 413, which can separate the adhesive adhering to the first adapter 412 from the second adapter 413 through the annular groove 417, further ensuring that the adhesive stays away from the rotating connection port 214 and prevents leakage. The third adapter 414 is used to fit the first bearing 44.

[0051] The fourth adapter 415 is used to fit the cylindrical gear 46. A limiting notch 4151 is provided on the peripheral wall of the fourth adapter 415 to ensure better locking and connection when assembled with the cylindrical gear 46, preventing free rotation. The fifth adapter 416 is used to fit the second bearing 45.

[0052] like Figure 3 As shown, the rotary drive component 5 includes a rotary motor 51 and a drive wheel 52. The rotary motor 51 drives the drive wheel 52 to rotate. The drive wheel 52 is connected to the synchronous pulley 48 through a belt 53. The synchronous pulley 48 rotates or stops along with the drive wheel 52.

[0053] In this embodiment, four glue-filling heads 31 are driven by a rotary motor 51 and are always in a rotating state. The glue-filling heads 31 have glue-inlet channels 314 evenly distributed on them, which are connected to the central inlet 313. This allows the glue-filling heads 31 to transfer glue into the glue-inlet channels 314 when rotating, and form a glue film on the periphery of the inlet 313. When this rotary external glue-filling mechanism is running, the end of the tube only needs to pass through the glue-filling port 213 and then be inserted into the inlet 313 of the glue-filling head 31 until the tube end abuts against the limiting head 321. During the process of the tube entering and exiting, a glue film will be formed on the outer wall of the tube, and the tube will be evenly glued.

[0054] In practical use, the bottom of this rotary conduit external glue-applying mechanism can be connected to an upper and lower drive mechanism. The whole assembly is placed between the conduit conveying line and the outlet of the connector to be assembled. After the conduit is in place, the external glue-applying mechanism rises, and the conduit extends into the external glue-applying mechanism to apply glue. After the glue application is completed, the mechanism retracts and lowers to free up assembly space. The conduit with glue is directly assembled with the connector, and the glue application and assembly work are completed simultaneously at the same station.
