Description

Technical Field

[0001] This utility model relates to the field of coated bracket manufacturing technology, and in particular to an adhesive tooling. Background Technology

[0002] Medical covered stents with duckbill valves are composite medical devices that combine the one-way check function of a duckbill valve with the support characteristics of a covered stent. They are commonly used in vascular interventional therapy, catheter drainage, and other applications. A duckbill valve is a one-way valve, typically made of rubber or silicone, and its shape resembles a duck's bill. The duckbill valve is primarily used to control the unidirectional flow of fluids, preventing backflow or reverse flow. It opens under positive pressure, allowing liquid or gas to pass through, and closes under reverse pressure, preventing backflow of liquid or gas. In medical covered stents, bonding and fixation are key processes.

[0003] Due to the small size of the duckbill valve, it is difficult to automate the bonding process. Currently, the main method is to manually apply adhesive to the duckbill valve and then assemble it onto the film-coated bracket for bonding and fixation. However, this purely manual positioning and bonding method is prone to problems such as the duckbill valve being positioned too high, too low, or off-center, which reduces product yield and has low bonding efficiency.

[0046] In this embodiment, the movable component 30 can be a pressure rod or a movable component with a rod-like structure. The top of the pressure rod can be a manually operated operating part, and the bottom of the pressure rod is a pressing part 301 designed to fit the duckbill valve 100. Specifically, the pressure rod forms the aforementioned sleeve arm, the shape of the placement position 201 is adapted to fit the shape of the duckbill valve 100, and the pressing part 301 of the pressure rod is a contoured notch adapted to the upper half of the placement position 201. When the pressing part 301 presses against the duckbill valve 100 on the placement position 201, the glued part 101 of the lower half of the duckbill valve 100 is exposed.

[0047] It is understood that this utility model proposes a bonding fixture for the duckbill valve 100 of a medical covered stent 200, which improves product quality, solves problems such as the duckbill valve 100 being positioned too high, too low, or eccentrically, improves product yield, and enhances bonding efficiency.

[0048] To facilitate the placement of the duckbill valve 100 and prevent the duckbill valve 100 from shifting during the bonding process, in one embodiment, the bonding fixture 20 may include a support block 21 and a rod 22 disposed on the support block 21. The top end of the rod 22 is provided with a contoured tip 23 to form a placement position 201.

The upper part of the pressure rod slides up and down within the positioning hole 12a of the fixing plate 12, and the lower part has a concave wedge-shaped structure that can contact and fit with the top of the bonding fixture 20.

[0056] In this embodiment, a protective pad made of flexible material can be provided at the contoured notch of the movable part 30, which can effectively prevent damage to the duckbill valve 100 and help to further improve product quality.

[0057] The working process and working principle of this bonding fixture are as follows:

[0058] (1) Lift the pressure rod by hand and place the molded duckbill valve 100 on the bonding jig 20, such as Figure 10 As shown;

[0059] (2) Apply adhesive around the lower half of the duckbill valve 100, such as... Figure 11 As shown;

[0060] (3) Insert the film-coated bracket 200 onto the pressure rod from the bottom, with the part of the film-coated bracket 200 to which the duckbill valve 100 needs to be bonded facing upwards, such as... Figure 12 As shown;

[0061] (4) Press the lever down, so that the pressing part 301 of the lever contacts and adheres to the top of the duckbill valve 100, pressing down the duckbill valve 100. Figure 13 and Figure 14 As shown;

[0062] (5) Gently slide the coated bracket 200 to the lowest bonding position and let it stand for a period of time. At this time, the adhesive part 101 of the duckbill valve 100 and the coated bracket 200 begin to bond and cure together. Figure 15 and Figure 16 As shown;

[0063] (6) Lift the pressure rod and remove the film-coated bracket 200 after the duckbill valve 100 is bonded, as shown. Figure 17 As shown.
