[0021] This application provides a winding tool 100, see Figure 1 , Figure 1 It is a structural schematic diagram of an embodiment of the winding tool provided by this application.
[0022] The winding tool 100 includes a mounting frame 101 and a linear drive member 10 and a rotating drive member 20 arranged on the mounting frame 101, wherein the linear drive member 10 includes a core shaft 12, and a connecting position 120 is provided at the end of the core shaft 12, the connecting position 120 is used to connect the workpiece, and the core shaft 12 is used to drive the workpiece to move along the axis of the core shaft 12; the winding assembly 30 includes a wire wheel 32 and a winding bracket 34, the winding bracket 34 is rotatably arranged on the core shaft 12, the wire wheel 32 is installed with a silk thread, and the silk thread is guided to the end of the core shaft 12 through the winding bracket 34; the rotating drive member 20 is connected to the winding bracket 34 for driving the winding bracket 34 to rotate around the axis of the core shaft 12 when the core shaft 12 moves, so that the silk thread is wound around the workpiece.
[0023] The workpiece may be an occluder or other devices. In this embodiment, a braided mesh of an occluder is taken as an example for description, and the winding tool 100 is used to perform a winding process on the braided mesh.
[0024] The braided mesh is pulled to move in a straight line by the core shaft 12, and the winding bracket 34 is driven to rotate in combination with the rotating driving member 20, so that the wire of the wire wheel 32 can be evenly wound on the braided mesh with high winding efficiency.
[0025] The linear drive component 10 can be a cylinder, and the core shaft 12 is the cylinder shaft. The cylinder can drive the cylinder shaft to move along its axis; the linear drive component 10 can also include a motor, a transmission mechanism and a core shaft 12. The motor drives the core shaft 12 to move linearly through the transmission mechanism. The transmission mechanism can be a belt drive mechanism or a gear rack drive mechanism.
[0026] The connection point 120 at the end of the core shaft 12 can be a hook, and a point of the woven mesh can be fixed on the hook, and the woven mesh is pulled along a straight line by the hook. The hook has a simple structure and is efficient in connecting workpieces such as woven mesh, and the connection method is also convenient enough.
[0027] Optionally, the connection position 120 may also be a clamp, which can clamp and fasten the woven mesh.
[0028] The winding bracket 34 is rotatably arranged on the core shaft 12, that is, the winding bracket 34 can rotate around the axis of the core shaft 12, wherein the winding bracket 34 can be rotatably arranged on a base, and the core shaft 12 is passed through the winding bracket 34, so that when the core shaft 12 is extended and retracted along its axial direction, the winding bracket 34 can still rotate around the axis.
[0029] The wire wheel 32 is connected to the winding bracket 34 and rotates with the winding bracket 34. The wire wheel 32 is wound with silk thread. The wire wheel 32 can rotate under the traction of the silk thread to continuously release the silk thread, so that the silk thread is guided by the winding bracket 34 and continuously wound on the woven mesh to gather the woven mesh into a rod-shaped structure.
[0030] The winding bracket 34 includes a rotating drum 342 and an extension frame 344. The rotating drum 342 is relatively sleeved on the core shaft 12. The extension frame 344 is connected to one end of the rotating drum 342 and extends outward. Before winding, the extension frame 344 extends away from the end of the rotating drum 342 to the connection position 120 of the core shaft 12 to facilitate winding onto the braided mesh.
[0031] Furthermore, the end of the core shaft 12 is further provided with a fixing plate 122 located on one side of the connection position 120. The fixing plate 122 is used to fix the wire. The fixing plate 122 is provided with a fixing hole, and the end of the wire is connected to the fixing hole to provide a support point for the wire. When the winding bracket 34 rotates, the wire can be reliably wound on the braided mesh, avoiding the risk of the wire falling off the braided mesh.
[0032] Optionally, the fixing plate 122 may also be provided with a wire groove, to which the ends of the wires are connected.
[0033] By setting a fixing plate 122 on one side of the connection position 120, and the end of the silk thread can be fixed on the fixing plate 122, when the winding bracket 34 rotates, the silk thread can be wound on the woven mesh starting from the fixing plate 122, and as the core shaft 12 pulls the woven mesh to move backward at a uniform speed, the silk thread can be evenly wound on the woven mesh. After the silk thread is wound on the woven mesh for a preset length, the connection between the end of the thread and the fixing plate 122 can be conveniently released, so that the wound woven mesh can be quickly removed.
[0034] Optionally, the ends of the silk threads may also be connected to the connection position 120 , or the ends of the silk threads may be directly connected to the braided mesh.
[0035] Furthermore, a plurality of guide wheels 340 are mounted on the winding bracket 34. The wire on the wire wheel 32 is guided along the path defined by the plurality of guide wheels 340 to the fixed plate 122. The plurality of guide wheels 340 are disposed on the extension frame 344 and can collectively form a tensioning path to prevent the wire from being derailed during winding and to allow the wire to be transmitted relatively smoothly and with less resistance.
[0036] In this embodiment, the rotating driving member 20 is a motor, the output end of the motor is provided with a first pulley, the winding bracket 34 is provided with a second pulley, and the first pulley and the second pulley are driven by a belt.
[0037] Optionally, the motor can also drive the winding bracket 34 to rotate through gear transmission.
[0038] Furthermore, the winding tool 100 also includes a chuck 40, which is located at one end of the core shaft 12. The chuck 40 is used to clamp the woven mesh so that the woven mesh between the core shaft 12 and the chuck 40 is in a straight strip shape, so that the silk thread can be efficiently wound on the straight strip woven mesh.
[0039] The chuck 40 can be a manual chuck, a pneumatic chuck, or an electric chuck, and the present application does not limit its specific type. The distance between the chuck 40 and the mandrel 12 can remain relatively constant, that is, the chuck 40 can move with the movement of the mandrel 12. For example, the mandrel 12 can be pulled by the braided mesh to move the chuck 40, or the mandrel 12 can be driven by other traction structures to drive the chuck 40 to move with it.
[0040] In this embodiment, the winding tool 100 also includes a connecting rod 41 and a guide rail 42. The guide rail 42 is slidingly arranged along an axis parallel to the core shaft 12. The chuck 40 is fixed on the guide rail 42. The connecting rod 41 connects the other end of the core shaft 12 and the guide rail 42 so that the chuck 40 moves with the core shaft 12.
[0041] The guide rail 42 is slidably mounted on a slider on the mounting frame 101 , and the slider is fixed to the mounting frame 101 , thereby ensuring that the guide rail 42 moves linearly along the axis of the core shaft 12 following the core shaft 12 .
[0042] Furthermore, the winding tool 100 further includes a sensing switch 43, which is used to sense the position of the chuck 40 and stop the operation of the linear drive member 10 and the rotary drive member 20 when the chuck 40 moves to a preset position.
[0043] The triggering of the induction switch 43 indicates that the winding of the braided mesh is completed, and the user can remove the braided mesh after the winding is completed. The induction switch 43 can also protect the clamp 40 from being damaged by impact.
[0044] The sensing switch 43 can be set on the mounting frame 101 or on the slider of the mounting frame 101, and can confirm whether the chuck 40 has moved to the preset position by means of photoelectric sensing or acoustic wave sensing. The preset position is a position where the woven mesh can be wound with a preset length. The preset length can be freely customized by the user, and the user can adjust the preset length by adjusting the position of the chuck 40 on the guide rail 42.
[0045] In this embodiment, the winding tool 100 further includes a mesh guide bracket 44 fixedly disposed between the core shaft 12 and the chuck 40 . The mesh guide bracket 44 is used to gather the woven mesh passing through the mesh guide bracket 44 .
[0046] The mesh guide bracket 44 is fixed to the mounting frame 101, and can make the passing braided mesh move toward the winding bracket 34 in a gathered posture, thereby making it easier for the wire to be wound around the braided mesh, thereby improving the winding efficiency and quality.
[0047] Specifically, a top end of the mesh guide bracket 44 is provided with a converging groove for the woven mesh to pass through, and the open structure of the converging groove is conducive to installing the woven mesh thereon.
[0048] Optionally, the mesh guide bracket 44 may be provided with a constriction hole for the woven mesh to pass through.
[0049] Different from the prior art, the present application discloses a winding tool. A core shaft pulls the woven mesh in a straight line, and a rotating drive member drives the winding bracket to rotate, so that the wire from the reel can be evenly wound around the woven mesh. This replaces manual winding, improves winding quality, and increases winding efficiency.
[0050] The above description is merely an embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
