All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
As shown in fig. 1-2, an embodiment of the present application provides a needle winding mechanism including an inner needle body 1, an outer needle body 2, and a rotating wheel 5.
The inner needle body 1 forms the main body part of the winding needle, one end of the inner needle body 1 is connected with a mounting base 9, the other end of the inner needle body 1 is provided with a supporting tip 10, the supporting tip 10 is inserted into a needle nozzle which is independently arranged outside in the winding process, and the inner needle body 1 is driven to rotate through the mounting base 9 so as to complete the winding of the pole piece and the diaphragm.

For example, a guide rod is arranged on the inner needle body 1, a guide hole is arranged on the outer needle body 2, the extending directions of the guide rod and the guide hole are radial to the inner needle body 1, the guide rod is arranged in the guide hole in a penetrating mode, and a ball guide sleeve is arranged between the guide rod and the guide hole so that the guide rod and the guide hole are in sliding fit, and therefore the guide rod is stable and reliable in form of being matched with the guide hole through the ball guide sleeve, the resistance is small, and the reliability of the structure is improved. Moreover, be provided with the piece that resets 4 between outer needle body 2 and the interior needle body 1, this piece that resets 4 can set up to reset extension spring, can drive outer needle body 2 along radial be close to interior needle body 1 through reset extension spring, and then the completion of the reset of outer needle body 2 is assisted.
The rotating wheel 5 is connected to the inner needle body 1 and is rotatable with respect to the inner needle body 1, for example, a rotating shaft is provided at an outer periphery of the inner needle body 1, and the rotating wheel 5 is rotatably connected to the rotating shaft to achieve rotational connection with respect to the inner needle body 1.
The rotating wheel 5 is provided with a rotating plane, the rotating wheel 5 is provided with an annular outer circumferential surface and two circular end faces, the rotating plane is arranged on the circular end faces of the rotating wheel 5, and the rotating plane can be driven to rotate through rotation of the rotating wheel 5. And the rotating plane is in transmission connection with the outer needle body 2 through a spiral guide structure, and under the action of the spiral guide structure, when the rotating wheel 5 drives the rotating plane to rotate, the rotating plane can drive the outer needle body 2 to radially displace along the inner needle body 1 so as to change the outer diameter and the outer circumference of the winding needle.
In the working process, the rotating plane can be rotated in different directions by controlling the rotating wheel 5 to rotate in different directions, and the outer needle body 2 is enabled to be close to or far away from the inner needle body 1 along the radial direction under the action of the spiral guide structure, so that the outer diameter and the outer circumference of the winding needle are increased or reduced. For example, when the rotating wheel 5 drives the rotating plane to rotate along the first direction, under the transmission action of the spiral guide structure, the rotating plane drives the outer needle body 2 to be far away from the inner needle body 1 along the radial direction of the inner needle body 1, so that the overall outer diameter and the outer circumference of the winding needle are increased; when the rotating wheel 5 drives the rotating plane to rotate along the second direction, the rotating plane drives the outer needle body 2 to approach the inner needle body 1 along the radial direction of the inner needle body 1 under the transmission action of the spiral guide structure, so that the outer diameter and the outer circumference of the winding needle are reduced.

In the process of winding the winding needle, the winding needle mechanism further comprises a self-locking structure, wherein the self-locking structure is connected with the rotating wheel 5 and used for limiting the rotating wheel 5 to rotate relative to the inner needle body 1, so that the rotating wheel 5 rotates along with the inner needle body 1 in the process of winding the winding needle, the self-locking structure can limit the rotating wheel 5 to rotate relative to the inner needle body 1, the rotating wheel 5 can be prevented from rotating accidentally, the outer needle body 2 is prevented from displacing relative to the inner needle body 1, and the outer circumference of the winding needle is kept within a preset range, so that the winding quality is improved.
The needle winding mechanism includes a variable diameter driving assembly for controlling the rotation of the rotation wheel 5 to adjust the outer circumference of the needle. In the process that the variable diameter driving assembly controls the rotation wheel 5 to rotate relative to the inner needle body 1, the self-locking structure does not affect the rotation of the rotation wheel 5 relative to the inner needle body 1, that is, the priority of the variable diameter driving assembly controlling the rotation of the rotation wheel 5 is greater than the priority of the self-locking structure limiting the rotation of the rotation wheel 5 relative to the inner needle body 1. For example, the self-locking structure is set as a damping shaft, the rotating wheel 5 is rotationally connected with the inner needle body 1 through the damping shaft, the damping shaft limits the rotating wheel 5 to rotate relative to the inner needle body 1 in the process of winding the winding needle, and the reducing driving assembly overcomes the damping force of the damping shaft and controls the rotating wheel 5 to rotate relative to the inner needle body 1 in the process of adjusting the outer circumference of the winding needle.
In this solution, the needle winding mechanism includes a worm and gear pair, the worm and gear pair includes a rotating rod 6 and the rotating wheel 5, the rotating rod 6 is rotatably connected to the inner needle body 1 (the specific connection relationship is not limited herein, only the position of the rotating rod 6 needs to be fixed relative to the inner needle body 1, and the rotating rod 6 can rotate relative to the inner needle body 1, besides, the rotating rod 6 can also be connected to other components fixed relative to the inner needle body 1), and the rotating rod 6 is in transmission connection with the rotating wheel 5, so that the rotating rod 6 can rotate to drive the rotating wheel 5, for example, the spiral teeth on the outer peripheral surface of the rotating rod 6 mesh with the teeth on the annular outer peripheral surface of the rotating wheel 5, and then the rotation motion of the rotating rod 6 is transmitted to the rotating wheel 5.
The inner needle body is provided with a first part and a second part which are axially arranged, the first part is correspondingly connected with a rotating wheel and a rotating rod, and the outer side of the second part is correspondingly connected with an outer needle body, so that the turbine worm pair and the outer needle body are respectively positioned at different axial positions of the inner needle body.
The outer needle body 2 is provided in plurality and arranged in the circumferential direction of the inner needle body 1, for example, the outer needle body 2 is provided with two or three, preferably two. The outer circumference of the winding needle can be uniformly adjusted by simultaneously approaching and separating the plurality of outer needle bodies 2 from the inner needle body 1 along the radial direction, so that the flatness of the outer circumference of the winding needle is maintained. Correspondingly, a plurality of rotating wheels 5 are arranged, for example, two or three, preferably two, rotating wheels 5 are rotatably connected to the outer side of the inner needle body 1, and the rotating wheels 5 and the outer needle body 2 are in one-to-one transmission connection through a spiral guide structure, so that the rotating wheels 5 can be controlled to rotate relative to the inner needle body 1 at the same time, and the outer needle bodies 2 can be displaced radially relative to the inner needle body 1 at the same time under the transmission action of the spiral guide structure.
In combination, the rotating wheels 5 are provided with a plurality of rotating rods 6, one rotating rod 6 is in transmission connection with the plurality of rotating wheels 5 to form a plurality of worm and gear matching structures, so that the rotating wheels 5 can be controlled to rotate with high precision by controlling the rotating rods 6 to rotate due to the fact that worm and gear pairs have high transmission ratios, and further the displacement of the outer needle body 2 relative to the inner needle body 1 can be controlled with high precision, and high-precision diameter variation and outer circumference adjustment of the winding needle can be realized. Moreover, as the worm and gear pair has self-locking property, a plurality of rotating wheels 5 can be reversely self-locked through one rotating rod 6, so that the self-locking structure for limiting the rotation of the rotating wheels 5 relative to the inner needle body 1 is formed, namely, only the rotating rod 6 can drive the rotating wheels 5 to rotate, but the rotating rod 6 can not be driven by the rotating wheels 5 to rotate, thereby playing a role in safety protection and preventing the outer needle body 2 from centrifugal movement in the winding process.
In a specific scheme, when the rotating rod 6 drives the rotating wheels 5 to rotate, the rotating directions of the rotating wheels 5 are opposite, so that the driving acting forces applied to the rotating wheels 5 by the rotating rod 6 are opposite, so that the stress on the rotating rod 6 is balanced, and the axial displacement of the rotating rod 6 is avoided.
It will be appreciated that, in order to stabilize the adjustment variation of the outer circumference of the winding needle, the radial displacement amounts of the plurality of outer needle bodies 2 relative to the inner needle body 1 need to be uniform after the rotating rod 6 rotates by a specific angle, and the displacement directions of the plurality of outer needle bodies 2 are opposite, that is, the plurality of outer needle bodies 2 can be simultaneously close to or simultaneously far from the inner needle body 1. For example, after the rotating rod 6 rotates by a specific angle or a specific number of turns, the plurality of rotating wheels 5 rotate by a consistent angle or number of turns, and at the same time, the rotating directions of the plurality of rotating wheels 5 are opposite, or the guiding directions of the spiral guiding structures provided on the plurality of rotating wheels 5 are opposite.
In some preferred embodiments, the reducing driving assembly is used for being in transmission connection with the rotating rod 6, and the rotating rod 6 can be driven to rotate relative to the inner needle body 1 through the reducing driving assembly, for example, the reducing driving assembly is connected to the frame, and the reducing driving assembly has a driving end, and the driving end can be close to and far away from the rotating rod 6. In the working process, when the peripheral length of the winding needle needs to be adjusted, the driving end is close to the rotating rod 6, so that the driving end is in transmission connection with the rotating rod 6; when the winding needle is required to be wound, the driving end is far away from the rotating rod 6, so that the driving end is disconnected from the transmission connection with the rotating rod 6.
The driving end of the reducing driving assembly is in non-contact transmission connection with the transmission connection of the rotating rod 6, the non-contact transmission connection can be in magnetic transmission connection, for example, the driving end of the reducing driving assembly and the end part of the rotating rod 6 are arranged to be magnetic connectors capable of being in magnetic transmission, and the two magnetic connectors are close to each other to complete transmission connection. Therefore, the transmission connection can be completed only by the diameter-variable driving assembly close to the rotating rod 6, and compared with mechanical transmission, the device has the advantages of no need of butt joint of two acting parts, simple structure and convenience in operation.
In this embodiment, the spiral guide structure includes a spiral groove 7 and a guide post 8, wherein the spiral groove 7 is provided on the rotation plane of the rotation wheel 5, the spiral groove 7 is provided around the rotation axis of the rotation wheel 5, and the spiral groove 7 gradually approaches or departs from the rotation axis of the rotation wheel 5 in the extending direction of itself. The guide post 8 is disposed on the outer needle body 2, for example, the rotating wheel 5 and the outer needle body 2 are arranged along the axial direction of the inner needle body 1, and the guide post 8 is disposed at one end of the outer needle body 2 near the rotating wheel 5. One end of the guide post 8 is fixedly connected with the outer needle body 2, the other end of the guide post extends into the spiral groove 7 and can slide and displace along the extending direction of the spiral groove 7, when the rotating wheel 5 drives the spiral groove 7 on the rotating plane to rotate along the rotating axis of the rotating wheel 5, the guide post 8 slides and displaces in the spiral groove 7 and gradually approaches or departs from the rotating axis of the rotating wheel 5, so that the outer needle body 2 gradually approaches or departs from the rotating axis of the rotating wheel 5, and the outer needle body 2 can radially displace relative to the inner needle body 1 due to the fact that the rotating axis of the rotating wheel 5 is fixed relative to the inner needle body 1, and then the outer needle body 2 gradually approaches or departs from the inner needle body 1. So, through the form of helical groove 7 and guide post 8 complex, can change the rotation action of rotor wheel 5 (helical groove 7) into the linear motion of outer needle body 2 (guide post 8), simple structure, it is reliable and stable, the transmission ratio of helical groove 7 and guide post 8 is great moreover, is favorable to realizing reducing and outer perimeter regulation with high accuracy.
Wherein the guide posts 8 are provided in a plurality, such as two, three or four. The plurality of guide posts 8 are arranged along the radial direction of the rotating wheel 5 such that the plurality of guide posts 8 are respectively located at a plurality of different radial positions within the spiral groove 7, for example, one guide post 8 is located at an inner ring of the spiral groove 7 and the other guide post 8 is located at an outer ring of the spiral groove 7. In this way, the stability of the helical guiding structure can be improved by the plurality of guiding studs 8, and the transmission reliability can be improved, when one guiding stud 8 fails in connection, the other guiding stud 8 can remain in connection.
It should be noted that, the guide post and the outer needle body may be an integral structure or a split structure, i.e., the guide post may be a part of the outer needle body or may be fixed or connected to the outer needle body.
In addition, the spiral guide structure can also be arranged in a mode that the spiral bulge is matched with the guide groove, the guide groove can slide and displace along the spiral bulge, and the rotation motion of the spiral bulge can be converted into the linear motion of the guide groove.
In a specific embodiment, the rotation plane is perpendicular to the rotation axis of the rotation wheel 5, and the rotation plane is perpendicular to the axial direction of the inner needle 1, i.e. the rotation axis of the rotation wheel 5 is parallel to the axial direction of the inner needle 1. In this way, in the process of rotating the rotating wheel 5, the distance between the rotating plane and the outer needle body 2 is kept unchanged, and the distances between each position on the rotating plane and the outer needle body 2 are equal, so that the guide post 8 is kept in the spiral groove 7, and the reliability and stability of the spiral guide structure are further improved.
Of course, in other embodiments, the plane of rotation may be inclined with respect to the axial direction of the inner needle 1, in which case it is necessary that the guide post 8 be elastically telescopically coupled to the outer needle 2 so that the guide post 8 is retained in the helical groove 7 in the plane of rotation.
In some embodiments, the inner side of the inner needle 1 is provided with an expansion assembly 3, the expansion assembly 3 being controllably expandable and contractible in the radial direction of the inner needle 1, the expansion assembly 3 on the inner side of the inner needle 1 being capable of clamping the septum when the expansion assembly 3 expands in the radial direction of the inner needle 1, and the expansion assembly 3 on the inner side of the inner needle 1 being capable of releasing the septum when the expansion assembly 3 contracts in the radial direction of the inner needle. Therefore, the diaphragm is clamped and loosened by controlling the expansion and contraction of the expansion assembly 3, and the operation is simple and the control is convenient.
