Description

Technical Field

[0001] This invention relates to the field of medical catheter manufacturing technology, and in particular to an automatic adhesive coating and assembly device for medical catheters. Background Technology

[0002] The use of catheters in clinical treatment, surgical procedures, and patient care is becoming increasingly widespread. Medical catheters typically require assembly with connectors to ensure their sealing and functionality during use, such as in infusion kits that connect needles and drip bags. Traditional assembly methods rely heavily on manual operation, including catheter positioning, adhesive application, and connector insertion. However, manual operation is inefficient, making it difficult to meet the demands of mass production, and assembly accuracy is hard to guarantee. In the existing technology, the technology disclosed in Chinese patent CN103203870B only serves a fixing function and cannot effectively block the catheter. Furthermore, adhesive application still requires manual operation, which may lead to uneven adhesive application or adhesive entering the catheter, causing blockage or contamination, thus affecting product quality.

[0003] In view of this, the inventor made a new invention. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an automated adhesive coating and assembly device for medical catheters, which has the advantages of high assembly quality and full automation.

[0005] To achieve the above objectives, the present invention provides an automatic adhesive coating and assembly device for medical catheters, comprising a catheter feeding mechanism, a plug-in feeding mechanism, and an adhesive coating and positioning mechanism. The catheter feeding mechanism is used to transport the catheter to the adhesive coating and positioning mechanism, and a plug-in pushing device is provided between the plug-in feeding mechanism and the adhesive coating and positioning mechanism.

[0006] The adhesive positioning mechanism is provided with a first clamping plate and a second clamping plate. The first clamping plate is provided with a first positioning groove, and the second clamping plate is provided with a second positioning groove. The first positioning groove can cooperate with the second positioning groove to form a positioning hole for fixing the conduit. The first positioning groove is provided with an adhesive injection hole, which can be used to apply adhesive around the conduit.

[0007] The plug-in feeding mechanism is provided with a material conveying channel for feeding the connector. The discharge end of the material conveying channel is provided with a first clamp. The first clamp is used to clamp the connector and transport it to the vicinity of the glue positioning mechanism so that the connector can be inserted into the positioning hole and connected to the guide tube.

[0008] The insert pushing device is equipped with a retractable positioning rod, which can pass through the connector and be inserted into the conduit in the positioning hole to block the opening of the conduit.

[0009] Furthermore, the plug-in feeding mechanism includes a first driving mechanism and a damping limiting device. The first driving device can drive the first clamp to move laterally and vertically. At least two damping limiting devices are provided to limit the front and rear positions of the first clamp's lateral movement.

[0010] Furthermore, the insertion device is provided with a second clamp and a second drive mechanism for driving the second clamp to move laterally and vertically. The second clamping device can take over clamping the connector on the first clamp, and the second drive mechanism can drive the second clamp to push the connector into the positioning hole so that the connector is inserted into the guide tube.

[0011] Furthermore, the plug-in pushing device is provided with a first positioning frame and a third driving mechanism. The first positioning frame is provided with a support hole that is axially aligned with the positioning hole. The rod body of the positioning rod passes through the support hole, and the rear end of the positioning rod is provided with a limiting member that is connected to the third driving mechanism.

[0012] Furthermore, the plug-in propulsion device is equipped with a damping limiting device for limiting the displacement distance of the second connecting plate.

[0013] Furthermore, the conduit feeding mechanism includes a third clamp and a movable traction table. A second positioning frame is provided on the traction table. The third clamp can hold the conduit, so that the conduit is placed between the first positioning groove and the second positioning groove.

[0014] Furthermore, the adhesive positioning mechanism is equipped with cylinder a for driving the first clamping plate to move up and down, and cylinder b for driving the second clamping plate to move up and down. Cylinder a and cylinder b drive the first clamping plate and the second clamping plate in sequence, so that the first positioning groove and the second positioning groove combine to form a positioning hole.

[0015] Furthermore, the first clamping plate is provided with a plurality of V-shaped grooves in sequence, the first positioning groove is provided at the bottom of the V-shaped groove, the second clamping plate is provided with a triangular protrusion corresponding to the V-shaped groove, and the second positioning groove is provided at the tip of the triangular protrusion. The triangular protrusion can be fitted with the V-shaped groove, so that the first positioning groove and the second positioning groove are combined to form a positioning hole.

[0016] Furthermore, the first clamping plate is provided with clamping plate a and clamping plate b, and the second clamping plate is provided with clamping plate c and clamping plate d. Clamping plate a and clamping plate c are fitted together, and clamping plate b and clamping plate d are fitted together, so that the positioning hole is divided into two parts and clamps and fixes the guide tube in sequence.

[0017] Furthermore, both the first positioning groove and the second positioning groove are provided with an expansion groove.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figures 1 to 10 The present invention will be described in detail.

[0033] An automatic adhesive coating and assembly device for medical catheters according to the present invention includes a catheter feeding mechanism 1, an insert feeding mechanism 2, and an adhesive coating and positioning mechanism 3. The catheter feeding mechanism 1 is used to transport the catheter to the adhesive coating and positioning mechanism 3. An insert pushing device 4 is provided between the insert feeding mechanism 2 and the adhesive coating and positioning mechanism 3. Before assembly, the catheter is usually rolled up and generally placed in a specific unwinding device. The catheter feeding mechanism 1 of the present invention is used to pull the catheter to the adhesive coating and positioning mechanism 3. The adhesive coating and positioning mechanism 3 is used to apply adhesive to the catheter. The insert feeding mechanism is used to feed and load the connector 5, and finally insert the connector 5 into the catheter, thus completing the assembly of the connector 5 and the catheter.

[0034] Combined with appendix Figure 6 To be continued Figure 8As shown, the adhesive positioning mechanism 3 is provided with a first clamping plate 31 and a second clamping plate 32. The first clamping plate 31 is provided with a first positioning groove 33, and the second clamping plate 32 is provided with a second positioning groove 34. The first positioning groove 33 and the second positioning groove 34 can cooperate to form a positioning hole 35 for fixing the conduit. The first positioning groove 33 is provided with an adhesive injection hole 36, which can be used to apply adhesive to the outer surface of the conduit. The adhesive injection hole 36 is connected to a pipeline for supplying adhesive. After the conduit is transported to the designated position by the conduit feeding mechanism 1, the first positioning groove 33 and the second positioning groove 34 cooperate to form a positioning hole 35 to fix the conduit. Then, adhesive is injected into the positioning hole 35 through the adhesive injection hole 36. The adhesive will squeeze into the gap between the conduit and the positioning hole 35, so that the surface of the conduit is coated with adhesive.

[0035] The adhesive positioning mechanism 3 is equipped with a cylinder a311 for driving the first clamping plate 31 to move up and down, and a cylinder b321 for driving the second clamping plate 32 to move up and down. Cylinders a311 and b321 sequentially drive the first clamping plate 31 and the second clamping plate 32, so that the first positioning groove 33 and the second positioning groove 34 combine to form a positioning hole 35. The first clamping plate 31 is located directly below the second support plate. After the guide tube is transported to the designated position, cylinder a311 drives the first clamping plate 31 to rise so that the first positioning groove 33 contacts the guide tube. After the first positioning groove 33 reaches the designated position, cylinder b321 drives the second clamping plate 32 to fall, so that the second positioning groove 34 and the first positioning groove 33 combine to form a positioning hole 35 to accurately fix the guide tube.

[0036] In embodiment 3 of the adhesive positioning mechanism, the first clamping plate 31 is sequentially provided with a plurality of V-shaped grooves 312, and the first positioning groove 33 is provided at the bottom of the V-shaped grooves 312. The second clamping plate 32 is provided with triangular protrusions 322 corresponding to the V-shaped grooves 312, and the second positioning groove 34 is provided at the tip of the triangular protrusions 322. The triangular protrusions 322 can be fitted with the V-shaped grooves 312, so that the first positioning groove 33 and the second positioning groove 34 combine to form a positioning hole 35. Medical catheters are mostly made of silicone or rubber tubing. Therefore, after the catheter is transported to the designated position by the catheter feeding mechanism, the front end of the catheter is not completely aligned with the first positioning groove 33. When the cylinder a311 drives the first clamping plate 31 to rise, the V-shaped grooves 312 can play a guiding role, and the V-shaped grooves 312 can guide the catheter into the first positioning groove 33. After the first clamping plate 31 and the second clamping plate 32 abut against each other, the triangular protrusion 322 engages with the V-shaped groove 312, so that the first positioning groove 33 and the second positioning groove 34 are completely merged, which can prevent glue from overflowing from the gap between the first positioning groove 33 and the second positioning groove 34 into the positioning hole 35. In this solution, multiple first positioning grooves 33 are provided, and the first clamping plate 31 and the second clamping plate 32 can cooperate to fix multiple conduits at certain intervals at the same time, which facilitates the batch assembly of conduits into connectors 5.

[0037] See appendix Figure 3The conduit feeding mechanism 1 includes a third clamp 11 and a movable traction platform 12. A second positioning frame 13 is mounted on the traction platform 12. The third clamp 11 can hold the conduit, positioning it between the first positioning groove 33 and the second positioning groove 34. The second positioning frame 13 has a slot for supporting the conduit. After entering the traction platform 12, the conduit passes through the second positioning frame 13 and is clamped and fixed by the third clamp 11. The traction platform 12 and the third clamp 11 can move together, and the traction platform 12 transports the conduit to the glue-applying positioning mechanism 3 by movement. Similarly, multiple traction platforms 12 and third clamps 11 can be arranged in sequence and combined into a set of conduit feeding mechanisms 1, enabling batch feeding of conduits. Multiple sets of conduit feeding mechanisms 1 can also be set. While one set of conduit feeding mechanisms 1 feeds the conduit to the glue-applying positioning mechanism 3 for glue application, another set can pull the conduit, ready to replace the previous set, thereby increasing the conduit feeding frequency and improving assembly production efficiency.

[0038] See appendix Figure 2 The plug-in feeding mechanism 2 is equipped with a feeding channel 21 for feeding the connector 5. A first clamp 22 is provided at the outlet end of the feeding channel 21. The first clamp 22 is used to clamp the connector 5 and transport it to the vicinity of the glue-applying and positioning mechanism 3, so that the connector 5 is inserted into the positioning hole 35 and connected to the guide tube. Multiple connectors 5 are fed sequentially through the feeding channel 21. When batch feeding is required, multiple feeding channels 21 and first clamps 22 can be correspondingly set. The first clamp 22 clamps the connector 5 and moves it to the positioning hole 35 in preparation for assembling the connector 5 with the guide tube. After the guide tube is glued, the connector 5 is inserted into the positioning hole 35 to be connected and fixed with the guide tube.

[0039] The plug-in feeding mechanism 2 includes a first driving mechanism 23 and a damping limiting device 24. The first driving device can drive the first clamp 22 to move laterally and vertically. At least two damping limiting devices 24 are provided to limit the forward and backward position of the first clamp 22 in the lateral movement. The first driving mechanism 23 includes a first connecting plate 231, a cylinder d232 that drives the first connecting plate 231 to move laterally, and a cylinder e233 that is fixedly connected to the first connecting plate 231. The first clamp 22 is connected to the cylinder e233. The cylinder d232 drives the first connecting plate 231 to move laterally, so that the first clamp 22 transports the connector 5 from the material conveying channel 21 to the glue feeding mechanism. The cylinder e233 drives the first clamp 22 to rise, so that the hole of the connector 5 for inserting the guide tube is aligned with the positioning hole 35. Then, the cylinder d232 drives the first clamp 22 to move further, so that the connector 5 can be inserted into the positioning hole 35. After the first connecting plate 231 is displaced to the designated position, it will abut against the damping limit device 24 to prevent the first clamp 22 from colliding with the material conveying channel 21 or the glue application positioning mechanism 3.

[0040] The insert pushing device 4 is equipped with a retractable positioning rod 41. The positioning rod 41 can pass through the connector 5 and be inserted into the conduit in the positioning hole 35 to block the conduit opening. After the first clamp 22 transports the connector 5 to a position aligned with the positioning hole 35, the positioning rod 41 extends, passes through the hole of the connector 5 to insert the conduit, and continues to extend until the positioning rod 41 is inserted into the conduit. Then, the glue injection hole 36 injects glue into the positioning hole 35. Because the positioning rod 41 blocks the conduit, the glue cannot enter the conduit.

[0041] In the embodiment where the connector 5 is inserted into the conduit, the insertion device 4 is provided with a second clamp 42 and a second drive mechanism 43 for driving the second clamp 42 to move laterally and vertically. The second clamping device can replace the clamping of the connector 5 on the first clamp 22. The second drive mechanism 43 can drive the second clamp 42 to push the connector 5 into the positioning hole 35, so that the connector 5 is inserted into the conduit. The second drive mechanism 43 includes a second connecting plate 431, a cylinder f432 for driving the second connecting plate 431 to move laterally, and a cylinder g433 fixedly connected to the second connecting plate 431. The second clamp 42 is fixedly connected to the cylinder g433. (See attached image for connector 5 shape.) Figure 10 The connector 5 has a first clamping area 51 and a second clamping area 52 on its outside. The first clamp 22 clamps the first clamping area 51 on the outside of the connector 5 and transports the connector 5 to a position aligned with the positioning hole 35. Then, the positioning rod 41 passes through the connector 5 and extends into the guide tube. Then, the cylinder g433 drives the second clamp 42 to descend. The second clamp 42 clamps the second clamping area 52 on the outside of the connector 5. At the same time, the first clamp 22 releases the connector 5 and descends to continue to pick up the connector 5 from the material conveying channel 21. During this process, after the guide tube is coated with glue, the cylinder f432 drives the second connecting plate 431 to move, thereby causing the second clamp 42 to insert the connector 5 into the positioning hole 35 and connect it to the guide tube. After that, the cylinder f432 and the cylinder g433 drive the second clamp 42 to reset in sequence. In this solution, the second clamp 42 takes over from the first clamp 22 to insert the connector 5 into the conduit, which allows the first clamp 22 to return to the material conveying channel 21 in advance, saving the time of the first clamp 22 waiting for the conduit to be coated with glue and for the connector 5 to be inserted into the conduit, thus speeding up the assembly speed of the connector 5 and further improving the assembly production efficiency.

[0042] The insertion device 4 is equipped with a first positioning frame 44 and a third driving mechanism 45. The first positioning frame 44 has a support hole 441 axially aligned with the positioning hole 35. The rod of the positioning rod 41 passes through the support hole 441, and the rear end of the positioning rod 41 is provided with a limiting member 411 connected to the third driving mechanism 45. The distance between the first positioning frame 44 and the adhesive positioning mechanism 3 is relatively fixed. The support hole 441 can fix the extension and retraction position of the positioning rod 41 so that the positioning rod 41 can be accurately inserted into the conduit inside the positioning hole 35. The third driving mechanism 45 includes a cylinder h451 and a push plate 452. The limiting member 411 is fixedly connected to the push plate 452. The cylinder h451 drives the push plate 452 to advance, causing the positioning rod 41 to extend. After the push plate 452 advances a certain distance, when the limiting member 411 approaches or abuts the first positioning frame 44, the positioning rod 41 can no longer extend. This limits the extension distance of the positioning rod 41 and avoids the positioning rod 41 from over-extending and puncturing or scratching the conduit.

[0043] The plug-in pushing device 4 is also equipped with two damping limiting devices 24 for limiting the displacement distance of the second connecting plate 431, so as to prevent the second clamp 42 from colliding with the first positioning frame 44 or the glue-applying positioning mechanism 3.

[0044] The first clamping plate 31 is provided with clamping plate a313 and clamping plate b314, and the second clamping plate 32 is provided with clamping plate c323 and clamping plate d324. Clamping plates a313 and c323 are fitted together, and clamping plates b314 and d324 are fitted together, so that the positioning hole 35 is divided into two parts and clamps and fixes the guide tube in sequence. There are two cylinders a311, which drive clamping plates a313 and b314 respectively, and there are also two cylinders b321, which drive clamping plates c323 and d324 respectively. In the assembly sequence of the connector and the conduit, after the conduit is transported above the first positioning groove 33, clamping plates a313 and c323 are fitted together to fix the conduit. Then clamping plates b314 and d324 are fitted together, positioning rod 41 is inserted into the conduit, glue enters and exits through the glue injection hole 36, connector 5 is inserted into the front end of the conduit, then clamping plates b314 and d324 separate, connector 5 continues to advance, connector 5 is inserted into the conduit and the assembly is completed. After that, clamping plates a313 and c323 separate, positioning rod 41 retracts, and finally the conduit feeding mechanism 1 transports the conduit with the connector 5 assembled away.

[0045] Both the first positioning groove 33 and the second positioning groove 34 are provided with an expansion groove 37. When the first positioning groove 33 and the second positioning groove 34 are combined, the positioning hole 35 has a flared portion that can accommodate the front end of the connector 5. The connector 5 is relatively wide on the outside, and the flared portion is in the shape of a trumpet, which makes it easy for the connector 5 to be inserted into the positioning hole 35.

[0046] The material conveying channel 21 is provided with a baffle plate 25 at the discharge end. The baffle plate 25 is provided with a discharge port 26 into which the first clamp 22 can extend. The plug-in feeding mechanism 2 is provided with a cylinder c27 for driving the baffle plate 25 to rise and fall. When the connector 5 at the front end of the conveying channel 21 is ready to be loaded, the first clamping area 51 outside the connector 5 will extend beyond the conveying channel 21 and the front end of the connector 5 will abut against the baffle plate 25. The first clamping area 51 outside the connector is located inside the discharge port 26. After the first clamp 22 extends into the discharge port 26 and clamps the connector 5, the cylinder c27 drives the baffle plate 25 to rise and offset the position of the baffle plate 25. Then the cylinder d232 drives the first clamp 22 to move, so that the first clamp 22 takes the connector 5 out of the conveying channel 21. When the first clamp 22 leaves, the cylinder c27 drives the baffle plate 25 to fall, so that the baffle plate 25 blocks the discharge end of the conveying channel 21, thereby allowing the connectors 5 in the conveying channel 21 to be discharged one by one.

[0047] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
