Description

Technical Field

[0001] This utility model relates to the field of implantable medical device manufacturing, and in particular to a stent weaving device. Background Technology

[0002] Stents are implantable medical devices widely used in clinical treatment. In clinical practice, they provide support to improve tissue function or assist in treatment. For example, after sinus stent implantation, it supports the sinus cavity, keeps the nasal passages open, promotes postoperative recovery, and improves the treatment effect for sinus diseases. Sinus stents belong to a type of flexible stent; these stents are typically made of polymer wires woven into a three-dimensional structure, possessing excellent flexibility and elasticity while providing good permeability.

[0003] Currently, these stents are mainly manufactured manually using a braiding method. This involves providing a braiding mold; at the start of braiding, the mold is compressed axially, and workers manually fix the head of the thread to the thread end fixing structure on the side of the mold. The thread is then wound sequentially around multiple hook structures on the mold according to a specific pattern. When the stent is fully formed, the winding is stopped, and the tail of the thread is fixed to the tail fixing structure on the side of the mold (usually on a different side from the thread end fixing structure; the thread end fixing structure and the tail fixing structure generally have fixed and released states, allowing the thread to be fixed or released). After winding, the mold is released axially and put into a tensioned state to tighten the thread. The intersections of the threads are then fixed to ensure that the pre-set three-dimensional structure is maintained during the subsequent removal of the stent from the mold and implantation into the patient. The specific structure of the braiding mold can be referenced from existing technologies, such as the braiding mold disclosed in CN215668427U.

[0004] However, current manufacturing technology has the following problems: First, manual weaving is inefficient and cannot meet the needs of mass production; second, manual weaving lacks precision: manual operation makes it difficult to ensure the uniformity of weaving and the consistency of tension, resulting in inconsistent strength in different parts of the finished bracket and affecting product quality. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the low efficiency of manual bracing in the prior art and to provide a bracing bracing device.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] A braiding device for braiding supports includes a braiding die for winding wires, and the braiding device further includes a rotating component, a wire carrying component, and a control component.

[0008] The rotating component can drive the knitting die to rotate around the die rotation axis of the knitting die;

[0009] At least a portion of the wire-carrying assembly is located outside the braiding mold and is capable of carrying the wire and reciprocating along the direction of the mold's rotation axis to attach the wire to the attachment structure of the braiding mold.

[0010] The control component is electrically connected to the rotating component and the wire-carrying component;

[0011] The wire carrying assembly includes a magnetic tension structure for maintaining tension on the wire carried by at least a portion of the wire carrying assembly;

[0012] In this technical solution, by providing a braiding frame device, a rotating component and a wire-carrying component are respectively configured to drive the braiding die and the wire to move. A control component coordinates the relative movement of the rotating component and the wire-carrying component. During the movement, the wire is automatically braided on the braiding die to form a frame, thereby improving production efficiency and reducing human error. Furthermore, the movement trajectories of the rotating component and the wire-carrying component are simple, and their movement schemes have low requirements for mechanical structures and control systems, thus reducing the manufacturing cost of the braiding frame device and making it easy to control and maintain. The magnetic tension structure on the wire-carrying component can maintain the stability of the wire tension during the braiding process, ensuring a consistent tension distribution and uniform strength throughout the frame, improving product quality, and reducing wire breakage and uneven winding problems.

[0013] Preferably, at least a portion of the wire-carrying assembly is also capable of rotating along the radial axis of the braiding mold, attaching the wire to the wire end fixing structure and / or wire end fixing structure of the braiding mold.

[0014] In this technical solution, the above settings automate the weaving action at the beginning and end of the weaving process, which facilitates the fixing of the wire ends and / or the wire tails, reduces the possibility of wire slack during the weaving process, and further improves the automation level of the bracket weaving, thereby reducing the labor costs required for the bracket production process.

[0015] Preferably, the wire-carrying assembly further includes a winding structure and a wire-holding structure;

[0016] The winding structure carries one end of the wire and reciprocates along the direction of the rotation axis of the mold, thus attaching the wire to the attachment structure.

[0017] The wire-holding structure carries the other end of the wire;

[0018] The winding structure and the holding structure are separately configured, and the tension of the wire between the winding structure and the holding structure is maintained.

[0019] In this technical solution, the above-described configuration allows the winding structure to handle one end of the wire, while the holding structure handles the other end. These two separate components maintain the wire tension. This design ensures uniform wire tension at both ends during the braiding process, further enhancing the consistency of strength throughout the support structure and improving product quality.

[0020] Preferably, the rotating assembly further includes a side-push structure for compressing or releasing the weaving mold along the direction of the mold's rotation axis.

[0021] In this technical solution, the side-pushing structure ensures that the wire is properly tensioned after braiding, preventing the braided wire from coming loose from the mold, which is beneficial to the stability of the bracket and the strength after molding.

[0022] Preferably, the braiding device further includes a movable wire-cutting assembly for cutting the wire.

[0023] In this technical solution, the above settings automate the cutting action of the wire at the end, simplify the wire processing steps after the braiding is completed, further improve the automation level of the bracket braiding, and reduce the labor cost required for the bracket production process.

[0024] Preferably, the braiding device further includes a movable adjustment component for switching the thread end fixing structure and / or thread end fixing structure between a fixed state and a released state.

[0025] In this technical solution, the above-mentioned settings automate the fixing and releasing actions of the wire at the beginning and end of the weaving process. This facilitates fixing the wire and semi-finished bracket before and during weaving, and releasing the formed bracket after weaving for removal. This further improves the automation level of bracket weaving and reduces the labor costs required for bracket production.

[0026] Preferably, the rotating component is detachably connected to the weaving mold.

[0027] In this technical solution, the above-mentioned arrangement facilitates the removal and installation of the weaving mold from the rotating component to switch to the weaving process of the next bracket, without having to remove the bracket from the weaving mold before weaving the next bracket. Therefore, the efficiency and flexibility of the bracket weaving equipment are improved, making it easier to produce as many brackets as possible per unit time, and further reducing the manufacturing cost of the bracket.

[0028] Preferably, the braiding device further includes a moving component for mounting the braiding die onto the rotating component and / or removing the braiding die from the rotating component.

[0029] In this technical solution, the above-mentioned settings automate the assembly and disassembly process of the braiding mold and rotating components, simplify the processing steps before and after braiding, further improve the automation level of bracket braiding, and reduce the labor costs required for bracket production.

[0030] Preferably, the bracing weaving device further includes a position acquisition component;

[0031] The position acquisition component is electrically connected to the control component, and the position acquisition component is used to acquire the position of the weaving mold.

[0032] In this technical solution, the position of the knitting mold can be automatically collected through the above settings, thereby avoiding the knitting process when the knitting mold is in the wrong position, and also making it easier to adjust the position of the knitting mold to improve the knitting accuracy and product quality.

[0033] Preferably, the position acquisition component is also used to acquire the position of the thread end fixing structure and / or thread tail fixing structure of the braiding mold.

[0034] In this technical solution, the above settings can further locate the positions of the fixed structures at the beginning and end of the thread, thereby avoiding the weaving process when the positions of the beginning and end of the thread are incorrect, ensuring the accuracy of the starting and ending positions of the weaving, and thus improving the weaving precision and product quality.

[0035] The positive and progressive effects of this utility model are as follows:

[0036] In this technical solution, by providing a braiding frame device, a rotating component and a wire-carrying component are respectively configured to drive the braiding die and the wire to move. A control component coordinates the relative movement of the rotating component and the wire-carrying component. During the movement, the wire is automatically braided on the braiding die to form a frame, thereby improving production efficiency and reducing human error. Furthermore, the movement trajectories of the rotating component and the wire-carrying component are simple, and their movement schemes have low requirements for mechanical structures and control systems, thus reducing the manufacturing cost of the braiding frame device and making it easy to control and maintain. The magnetic tension structure on the wire-carrying component can maintain the stability of the wire tension during the braiding process, ensuring a consistent tension distribution and uniform strength throughout the frame, improving product quality, and reducing wire breakage and uneven winding problems.

[0068] Mold transfer assembly 8 Detailed Implementation

[0069] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment as an example.

[0070] like Figures 1-8 As shown, this embodiment provides a braiding device, which includes a braiding mold 11 for winding wire 12. The braiding device also includes a rotating component 2, a wire carrying component 3, and a control component (not shown in the figure).

[0071] The rotating component 2 can drive the knitting mold 11 to rotate around the mold rotation axis of the knitting mold 11.

[0072] like Figure 2 and Figure 3 As shown, at least a portion of the wire-carrying assembly 3 is located outside the braiding mold 11 and is capable of carrying the wire 12 and reciprocating along the direction of the mold rotation axis to attach the wire 12 to the attachment structure of the braiding mold 11.

[0073] A control component (not shown in the figure) is electrically connected to the rotating component 2 and the wire-carrying component 3. The rotating component 2 and the wire-carrying component 3 drive the braiding die 11 and the wire 12 to move, respectively. The control component coordinates the relative movement of the rotating component 2 and the wire-carrying component 3. During the movement, the wire 12 is automatically braided on the braiding die 11 to form a support, thereby improving production efficiency and reducing human error. Furthermore, the movement trajectories of the rotating component 2 and the wire-carrying component 3 are simple, and their movement schemes have low requirements for mechanical structure and control system, thus reducing the manufacturing cost of the support braiding equipment and making it easy to control and maintain.

[0074] like Figure 5As shown, in this embodiment, the wire-carrying assembly 3 includes a magnetic tension structure 31. The magnetic tension structure 31 is used to maintain the tension of at least a portion of the wire 12 carried by the wire-carrying assembly 3, so as to maintain the stability of the tension of the wire 12 during the braiding process, ensure that the wire 12 maintains a consistent tension distribution during the braiding process, so that the strength of the bracket is consistent throughout, improves product quality, and also reduces the problems of wire 12 breakage and uneven winding.

[0075] In this embodiment, at least a portion of the wire-carrying assembly 3 can also rotate along the radial axis of the braiding mold 11, attaching the wire 12 to the wire end fixing structure and the wire tail fixing structure of the braiding mold 11. This automates the braiding action of the wire 12 at the beginning and end of the braiding process, facilitates the fixing of the wire end and / or the wire tail, reduces the possibility of the wire 12 slack during braiding, and further improves the automation level of the bracket braiding, reducing the labor costs required for the bracket production process. Of course, in other embodiments, the wire-carrying assembly may also attach the wire only to the wire end fixing structure or the wire tail fixing structure.

[0076] In this embodiment, the wire-carrying assembly 3 further includes a winding structure and a holding structure. The winding structure carries one end of the wire 12 and reciprocates along the direction of the mold's rotation axis, hooking the wire 12 onto the hooking structure. The holding structure carries the other end of the wire 12. The winding structure and the holding structure are separately configured and maintain the tension of the wire 12 between them. In this way, the winding structure and the holding structure are responsible for the two ends of the wire 12 respectively. The two structures are separately configured and maintain the tension of the wire 12, ensuring that the tension of the wire 12 at both ends is uniform during the weaving process, further making the strength of the bracket consistent throughout and improving product quality.

[0077] In this embodiment, the winding structure further includes a winding X-axis module 321, a winding Y-axis module 322, a winding Z-axis module 323, a winding R-axis module 324, and a winding servo motor (not shown in the figure) corresponding to each winding module. The winding X-axis module 321, the winding Y-axis module 322, and the winding Z-axis module 323 work together to deliver the wire to a predetermined position.

[0078] like Figure 4 As shown, the wire passes through the inside of the guide needle 325 extending along the winding R-axis module 324 and rotates 180° around the winding R-axis module 324 to complete the mechanical movement when winding to the predetermined position. The four winding modules work together until the wire is wound into the desired structure on the braiding die.

[0079] In this embodiment, the rotating component 2 also includes a side-pushing structure 21, which is used to compress or release the braiding mold 11 along the direction of the mold rotation axis to ensure that the wire 12 can be properly tensioned after braiding, preventing the braided wire 12 from coming loose from the mold, which is beneficial to the stability of the bracket and the strength after molding.

[0080] Specifically, in this embodiment, the braiding die 11 has an upper cover, a lower cover, and a spring (not shown) sandwiched between the upper and lower covers. The side-pushing mechanism 21 can compress the spring during the braiding process and release the braiding die 11 after the braiding is completed. The spring can tighten the yarn to prevent the braided support from falling off the braiding die 11.

[0081] The side-pushing mechanism 21 has a mold fixing pin and a side-pushing linear module. The knitting mold 11 is fixed by the mold fixing pin, and the side-pushing linear module moves back and forth to press and release the knitting mold 11.

[0082] In this embodiment, the rotating component 2 includes a rotating servo motor, a rotating synchronous belt, and a clamping sleeve to achieve 360° infinite rotation of the knitting mold 11.

[0083] like Figures 6-8 As shown, in this embodiment, the braiding device also includes a movable wire-cutting component 4, which is used to cut the wire 12, thereby automating the cutting action of the wire 12 at the end, simplifying the wire 12 processing steps after braiding is completed, further improving the automation level of braiding, and reducing the labor cost required for the braiding production process.

[0084] In this embodiment, the wire-cutting assembly 4 can also be used to tighten the ends of the wire 12. The specific structure includes a wire-cutting X-axis module 41, a wire-cutting Y-axis module 42, a wire-cutting servo motor 43, a wire-cutting cylinder 44, a blade 45, and a tensioning shaft 46. The wire-cutting cylinder 44 has a sliding cylinder 47 underneath, used to clamp the wire 12 to ensure the stability of the braiding. The wire-cutting X-axis module 41 and the wire-cutting Y-axis module 42 can be adapted to braiding dies 11 of different specifications and sizes. Driven by the wire-cutting servo motor 43, they achieve high-precision clamping and wire-cutting operations. The blade 45 is fixed inside the wire-cutting assembly 4 and driven by the wire-cutting cylinder 44 to cut the wire 12, ensuring the integrity of the braiding. When the wire 12 begins to braid, the wire end needs to be clamped first, and then wound onto the braiding die 11. After braiding is completed, the wire end needs to be clamped first and then cut before the dies with the braided threads can be removed from the equipment; then the next die can be used for braiding.

[0085] In this embodiment, the braiding device further includes a movable adjustment component 5. The adjustment component 5 is used to switch the thread end fixing structure and the thread tail fixing structure between a fixed state and a released state, automating the fixing and releasing actions of the thread 12 at the beginning and end of braiding. This facilitates fixing the thread 12 and the semi-finished bracket before and during braiding, and releasing the formed bracket for removal after braiding, further improving the automation level of bracket braiding and reducing the labor costs required in the bracket production process. In other embodiments, the adjustment component can also be used to separately fix and release the thread end fixing structure or the thread tail fixing structure.

[0086] Specifically, in this embodiment, the adjustment component 5 includes a first electric screwdriver and a second electric screwdriver, which are electric screwdrivers. When the wire 12 begins and ends its weaving on the braiding mold 11, the wire end and the wire tail need to be wrapped around the wire end fixing structure and the wire tail fixing structure (both are screws in this embodiment). Then, the wire end fixing structure and the wire tail fixing structure are locked to fix the wire end and the wire tail, preventing the bracket from spreading out on the braiding mold 11. The first electric screwdriver and the second electric screwdriver are in a "Z" shape to prevent them from interfering with each other and affecting the weaving process. Since the wire end fixing structure and the wire tail fixing structure are located on both sides of the braiding mold 11, the first electric screwdriver and the second electric screwdriver are respectively set on both sides of the braiding mold 11.

[0087] In this embodiment, the rotating component 2 is detachably connected to the weaving mold 11, which facilitates the removal and installation of the weaving mold 11 from the rotating component 2 to switch to the weaving process of the next bracket, without having to remove the bracket from the weaving mold 11 before weaving the next bracket. Therefore, the efficiency and flexibility of the bracket weaving equipment are improved, making it easier to produce as many brackets as possible per unit time, and further reducing the manufacturing cost of the bracket.

[0088] In this embodiment, the bracing weaving equipment further includes a moving component 6, which is used to install the braiding die 11 onto the rotating component 2 and to remove the braiding die 11 from the rotating component 2. This automates the assembly and disassembly process of the braiding die 11 and the rotating component 2, simplifies the processing steps before and after braiding, further improves the automation level of bracing weaving, and reduces the labor costs required in the bracing production process. Of course, in other embodiments, the moving component can also be used alone to install the braiding die onto the rotating component, or to remove the braiding die from the rotating component.

[0089] Specifically, in this embodiment, the moving component 6 consists of a moving X-axis module, a moving Y-axis module, a moving Z-axis module, and a moving drive motor (not shown in the figure, used to drive each moving module). It can adapt to the gripping and placement of knitting dies 11 of different sizes, ensuring high-precision material handling. The moving Z-axis module is equipped with two grippers, capable of gripping two knitting dies 11 at a time, and is connected to two parallel rotating components 2 to improve efficiency. The camera detection system uses dual grippers to improve efficiency; the camera can determine whether there are products on the tray while ensuring material handling accuracy.

[0090] In this embodiment, the braiding device also includes a position acquisition component; the position acquisition component is electrically connected to the control component, and the position acquisition component is used to acquire the position of the braiding mold 11, so as to automatically acquire the position of the braiding mold 11, thereby avoiding the braiding process when the position of the braiding mold 11 is incorrect, and also facilitating the adjustment of the position of the braiding mold 11 to improve the braiding accuracy and product quality.

[0091] In this embodiment, the position acquisition component includes a camera, a light source, and a lens, and is located on the moving Z-axis module to adapt to the movement of the weaving mold 11.

[0092] In this embodiment, the position acquisition component is also used to acquire the positions of the thread start and end fixing structures of the braiding mold 11, in order to further locate the positions of the thread start and end fixing structures, thereby avoiding the braiding process when the thread start and end positions are incorrect, ensuring the accuracy of the braiding start and end positions, and improving braiding precision and product quality. Of course, in other embodiments, the position acquisition component can also be used to acquire the positions of the thread start or end fixing structures of the braiding mold separately.

[0093] In this embodiment, the braiding equipment also includes a mold conveying assembly 8 to realize the automatic conveying of the braiding mold 11. The mold conveying assembly 8 includes a conveying synchronous wheel, a conveying synchronous belt, a conveying servo motor, a conveying slide rail, and a conveying cylinder (not shown in the figure). It is equipped with a machine material picking station and a manual material feeding station, which makes the degree of manual intervention in the braiding process low: the machine operator only needs to thread the yarn when the machine is first turned on, and replace the braiding mold 11 at the manual material feeding station after the braiding is completed. No manual intervention is required during operation.

[0094] In this embodiment, the modular design also enables the equipment to quickly switch between products of different specifications, adapt to diverse production needs, and facilitate maintenance and replacement.

[0095] like Figure 9 As shown, this embodiment also provides a bracing method, which uses the bracing equipment described above, and the steps include:

[0096] S1, Location acquisition component for photographing and positioning the weaving mold 11;

[0097] S2, The gripper descends and clamps the weaving mold 11;

[0098] S3, The gripper moves to connect the weaving mold 11 and the rotating component 2;

[0099] Position acquisition component sensing cable head fixing structure and cable tail fixing structure;

[0100] If the end-of-line fixing structure and the end-of-line fixing structure are not detected, it means that the angle of the braiding mold 11 is incorrect. The rotary servo motor will adjust according to the set angle until the end-of-line fixing structure and the end-of-line fixing structure are detected.

[0101] S4. The cable-carrying assembly 3 moves to the upper position, and the wire needle 325 rotates 90° to wrap the wire 12 around the wire end fixing structure once.

[0102] S5. The wire needle 325 rotates 90° to maintain a vertical position, and the first electric screwdriver moves into place to lock the wire end fixing structure.

[0103] S6, the wire needle 325 begins to wind wire according to the set path;

[0104] S7. After the main body of the bracket is braided, the wire needle 325 wraps the wire 12 around the wire end fixing structure of the braiding mold 11.

[0105] S8, wire needle 325 clearance, second electric screwdriver locks the wire end fixing structure;

[0106] S9. The second electric screwdriver retracts, and the wire cutting assembly 4 clamps and cuts the wire 12.

[0107] S10, wire needle 325 and wire cutting assembly 4 are positioned;

[0108] S11, The grippers remove the weaving mold 11 and its support;

[0109] S12, The gripper connects the unwound braiding mold 11 and the rotating component 2;

[0110] S13. The gripper returns the wound product to the material handling station of the equipment.

[0111] S14, The location acquisition component takes pictures and locates the new weaving mold 11;

[0112] S15. Repeat steps S2-S14 to complete the remaining bracing work.
