The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1-4, the present application discloses a winding device, comprising: a winding needle 100 for winding the substrate; the plugging mechanism 200 is used for driving the winding needle 100 to extend out or retract; the rotation mechanism 300, the rotation mechanism 300 includes a first linkage 310 and a rotation driving member 320 for driving the first linkage 310 to rotate; the winding needle 100 is provided with a second linkage member 110, when the inserting and pulling mechanism 200 drives the winding needle 100 to extend, the second linkage member 110 contacts the first linkage member 310, and the autorotation driving member 320 drives the first linkage member 310 to rotate, so as to drive the second linkage member 110 and the winding needle 100 to rotate, thereby realizing the winding of the winding needle 100 on the substrate.

It is to be construed that the substrate is the base material constituting the electrical component. For example, when a winder is used to wind the capacitor core, the substrate typically includes plates and separators; when the winding machine is used for winding the battery core, the substrate generally includes a positive electrode plate, a negative electrode plate, and a diaphragm separating the positive electrode plate from the negative electrode plate. During winding, the winding needle 100 carries the substrate to rotate, so that the substrate is wound and molded around the winding needle 100; after the electric element is wound, the inserting and pulling mechanism 200 drives the winding needle 100 to recover and pull out the electric element, so that the electric element is convenient to feed; after the electrical component is removed, the inserting and pulling mechanism 200 drives the winding pin 100 to extend, so as to perform a new round of winding the electrical component.

In the traditional winding device, a driving mechanism for driving the winding needle to rotate is integrated, and the rotation driving mechanism is connected with the winding needle; in order to avoid mutual interference between actions of the rotation driving mechanism and the driving mechanism for driving the winding needle to be inserted and pulled, the rotation driving mechanism needs to drive the winding needle and the insertion and pulling driving mechanism to rotate together, or the insertion and pulling driving mechanism needs to drive the winding needle and the rotation driving mechanism to be inserted and pulled together, so that the related structure of the winding needle is complex, and the action load is large.

The present application provides a second linkage member 110 on a needle 100; when the inserting and pulling mechanism 200 drives the winding needle 100 to extend, the winding needle 100 drives the second linkage member 110 to contact the first linkage member 310; therefore, when the rotation driving member 320 drives the first linkage member 310 to rotate, the second linkage member 110 and the winding needle 100 can be driven to rotate, so that the winding needle 100 winds the substrate; the driving mechanism for driving the winding needle 100 to rotate can be divided into two parts by the first link 310 and the second link 110, and the whole rotation driving mechanism is prevented from operating with the winding needle 100, thereby simplifying the structure of the winding needle 100 itself and facilitating the operation of the winding needle 100.

The inserting and pulling mechanism 200 includes an inserting and pulling driving member 210 and an inserting and pulling guiding member 220, the winding needle 100 is slidably connected to the inserting and pulling guiding member 220, the inserting and pulling driving member 210 is connected to drive the winding needle 100 to move along the inserting and pulling guiding member 220, so that when the winding needle 100 extends, the second linkage member 110 contacts the first linkage member 310, and linkage is realized.

The station where the winding needle 100 arrives when extending is set as the working station, and the station where the winding needle 100 arrives when recovering is set as the avoiding station. The insertion guide 220 points from the avoidance station to the working station.

Referring to fig. 1 specifically, the output end of the plugging driving member 210 is connected to the winding needle 100, and when winding is required, the plugging driving member 210 drives the winding needle 100 to move toward the working station until the winding needle 100 contacts the substrate; when blanking is needed, the inserting and pulling driving member 210 drives the winding needle 100 to move towards the avoiding station until the winding needle 100 is far away from the electric element.

The plug driving member 210 may be a driving member such as a motor and a cylinder, and the plug guiding member 220 may be a guiding member such as a guide rod and a guide rail, which is not limited in the present application.

In order to protect the winding needle 100, the inserting and extracting mechanism 200 further comprises a buffer 230; the buffer member 230 is arranged near the working station and/or the avoiding station, when the winding needle 100 extends out or retracts, the buffer member 230 can abut against the buffer member 230, the buffer member 230 can reduce the impact force of the action of the winding needle 100, and the winding needle 100 is prevented from impacting other mechanisms or being separated from the plugging guide member 220 too fast; further, the buffer 230 also has a limiting function, so that excessive movement of the winding needle 100 can be avoided, and the winding needle 100 can correctly reach the working station and/or the avoiding station.

Wherein the buffer 230 may be a buffer; the buffers 230 are disposed at both ends of the extension direction of the inserting and extracting guide 220.

The self-rotating mechanism 300 provided by the application is arranged near a working station; when the inserting and pulling driving member 210 drives the winding needle 100 to reach the working position, the second linkage member 110 on the winding needle 100 contacts the first linkage member 310, so as to realize linkage. The first linkage member 310 and the second linkage member 110 may be a brake or a clutch engaged with each other by plugging, and include a driving portion disposed at an output end of the rotation driving member 320 and a driven portion connected to the winding needle 100, and the driven portion may move along with the driving portion after engaging with the driving portion, thereby implementing a linkage action.

In one embodiment, the first linkage member 310 and the second linkage member 110 are provided as idler wheels, and when the idler wheels are engaged, the linkage can be achieved through friction. Referring specifically to fig. 1, the end of the winding needle 100 not used for winding the substrate is provided with a cam, when the inserting and pulling mechanism 200 drives the winding needle 100 to move to the working position, the front end of the winding needle 100 contacts the substrate, and the cam at the end of the winding needle 100 contacts the cam of the first linkage member 310. At this time, the rotation mechanism 300 may be disposed on the same side of the substrate together with the winding needle 100, so as to facilitate the layout of the apparatus and prevent the rotation mechanism 300 from interfering with the winding of the substrate.

In order to ensure that the two idler wheels are stably linked, the friction force between the idler wheels needs to be ensured; in one embodiment, the surface of the idler wheel can be provided with concave-convex patterns, and the friction force between the idler wheel and the idler wheel is increased through the roughness of the wheel surface; in another embodiment, one of the idler wheels can be made of rubber, the rubber idler wheel is wear-resistant and oil-resistant, and the two idler wheels are meshed with each other, so that the friction force is stable, and the transmission is accurate. Specifically, it is preferable to provide the first linkage member 310 as a metal cam and the second linkage member 110 as a rubber cam. The first linkage member 310 is used as a driving wheel, so that the load is large, the required precision is high, and the effect of adopting a metal idler wheel is good; the second linkage member 110 is a rubber idler, and can realize effective linkage when engaged with a metal idler by using the characteristics of rubber.

Further, the rotation mechanism 300 further includes a first adjustment assembly 330 for driving the first linkage member 310 to move toward or away from the second linkage member 110.

As will be readily appreciated, when the inserting and extracting mechanism 200 drives the winding needle 100 to move, the first linkage member 310 at the working position may interfere with the inserting and extracting movement of the winding needle 100. Therefore, by arranging the first adjusting assembly 330, when the winding needle 100 is inserted and pulled, the first adjusting assembly 330 can be far away, so that the winding needle 100 can pass through conveniently; when the needle 100 is in place, the first adjustment assembly 330 drives the first linkage member 310 to abut against the second linkage member 110. Further, the first adjusting assembly 330 can also keep the first linkage member 310 against the second linkage member 110, so as to improve the mutual friction between the two and ensure the linkage effect.

In one embodiment, referring to fig. 1, the first adjustment assembly 330 includes an adjustment driving member 331 and an adjustment member 332 connected to the first linking member 310; the adjustment driving member 331 is coupled to and drives the adjustment member 332 to rotate around the mounting shaft 333, so as to drive the first linkage member 310 to approach or depart from the second linkage member 110 along the circular arc track. At this time, the mounting shaft 333 is disposed at the side of the working station away from the winding needle 100, the adjusting member 332 is rotatably disposed on the mounting shaft 333 through a bearing, and the first link 310 and the rotation driving member 320 are relatively fixedly disposed on the adjusting member 332; when the adjusting driver 331 drives the adjusting member 332 to rotate around the mounting shaft 333, the adjusting member 332 carries the first link 310 and the rotation driver 320 to rotate around the mounting shaft 333 synchronously. Furthermore, the adjustment driving member 331 is used for driving the adjustment member 332, so as to drive the first linkage member 310 to approach or depart from the second linkage member 110 in a swinging manner, so that the installation space of the whole rotation mechanism 300 can be saved, the movement stroke of the adjustment driving member 331 can be saved, and the response speed can be improved.

In other embodiments, the first adjustment assembly 330 can also be driven linearly to directly drive the first linkage member 310 and the rotation driving member 320 to move toward the winding needle 100 until the first linkage member 310 presses the second linkage member 110. The first link 310 and the rotation driving member 320 may be disposed on any side of the winding needle 100, and the present application is not limited thereto.

As will be readily appreciated, the rotation driving member 320 drives the winding pin 100 to rotate by the first and second linkage members 310 and 110, thereby winding the substrate. The electrical components wound from the substrate are generally of a predetermined size, depending on the process requirements. Therefore, the rotation driving member 320 preferably adopts a servo motor, and the number of rotation turns of the winding needle 100 can be precisely controlled by the servo motor, so as to ensure that the substrate with the preset length is wound every time, and finally, the electric element with the required configuration is obtained.

The application also discloses a winding machine, which comprises at least two groups of winding needles 100 and plugging mechanisms 200, wherein the winding needles 100 are provided with second linkage members 110, and the plugging mechanisms 200 correspond to the winding needles 100 one by one.

It should be noted that the winding machine provided by the application is a multi-station winding machine, and during operation, a plurality of groups of winding needles are respectively positioned at different stations to perform electric element preparation operation at different stages. Wherein the plurality of stations at least comprise a winding station and a blanking station. When the winding needle is positioned at the winding station, the winding needle clamps the base material to rotate, so that the base material forms an electric element; when the winding needle is positioned at the blanking station, the winding needle is pulled out from the electric element, so that the electric element is convenient to take away.

Further, the winding machine provided by the present application further includes a revolution mechanism 400 for driving the winding needles 100 to revolve, so that when one set of winding needles 100 is at the winding station, another set of winding needles 100 is at the discharging station.

After the winding needle 100 at the winding station winds the electric element for forming, the revolution mechanism 400 acts to drive each group of winding needles 100 to change stations, so that the winding needle 100 carrying the electric element reaches a blanking station to prepare for blanking of the electric element; and the winding needle 100, which was originally in the feeding station, is switched to the winding station, ready to start a new round of winding of the electrical components.

The revolution mechanism 400 includes a rotation shaft 410 and a revolution driving member 420 for driving the rotation shaft 410 to rotate, the inserting and extracting mechanism 200 is disposed on the rotation shaft 410, and the winding needle 100 is connected to the inserting and extracting mechanism 200.

In one embodiment, the winding machine includes two sets of winding pins 100. At this time, referring to fig. 2, the rotating shaft 410 may be a rectangular parallelepiped, the inserting and extracting guides 220 of the two groups of inserting and extracting mechanisms 200 may be oppositely disposed on two surfaces in the length direction of the rotating shaft 410, and the two groups of winding pins 100 are respectively slidably connected to one inserting and extracting guide 220; the inserting and pulling driving members 210 of the two inserting and pulling mechanisms 200 may be oppositely disposed on the other two surfaces of the length direction of the rotating shaft 410, and the output ends thereof are respectively connected to a set of winding pins 100. The revolution driving member 420 may be a motor, and an output end thereof is connected to the rotating shaft 410, and can drive the rotating shaft 410 and the two sets of winding needles 100 to revolve.

Wherein, the rotation mechanism 300 is arranged near the winding station; at the winding station, the inserting and pulling mechanism 200 drives the winding needle 100 to extend out to the working station, so that the second linkage member 110 arranged on the winding needle 100 can be contacted with the first linkage member 310.

Further, a winding mechanism 500 is arranged near the blanking station; the winding mechanism 500 comprises a third linkage member 510 and a winding driving member 520 for driving the third linkage member 510 to rotate, at the discharging station, the inserting and pulling mechanism 200 drives the winding needle 100 to extend out, the second linkage member 110 arranged on the winding needle 100 can be contacted with the third linkage member 510, and the winding driving member 520 drives the third linkage member 510 to rotate, so as to drive the winding needle 100 to rotate.

In order to ensure that the winding is continued, the base material is not set to a length necessary for winding one electric element. Thus, after one electric element is wound and molded, the base material is cut; the revolution mechanism 400 acts, so that the molded electric element is switched to a blanking station; at this time, the electric element needs to be terminated so that the cut tail of the base material is wound and fixed to the electric element. Thus, the winding mechanism 500 is provided to further drive the winding pin 100 to rotate, thereby completing the ending of the substrate.

The third link 510 is similar to the first link 310 in structure, and will not be described herein; the take-up drive 520 may be a motor.

Further, the winding mechanism 500 further includes a second adjustment assembly 540 for driving the third link 510 to move toward or away from the second link 110. The structure of the second adjusting element 540 is similar to that of the first adjusting element 330, and is not described herein again.

Further, the winding mechanism 500 further includes a positioning detection piece 530; the positioning detector 530 can detect the mark on the winding needle 100 so as to return the winding needle 100 to a fixed state after blanking.

It should be noted that, before winding the electric element, the winding needle 100 needs to clamp a portion of the substrate, pre-wind the portion of the substrate, and then insert another substrate to form the electric core. Specifically, taking an electrical element as an electrical core as an example, at a winding station, the plugging and unplugging mechanism 200 drives the winding needle 100 to extend to a working station, and the winding needle 100 clamps a diaphragm in a substrate; after the winding needle 100 clamps the diaphragm, the autorotation driving part 320 drives the first linkage part 310 to rotate and drives the second linkage part 110 and the winding needle 100 to rotate, so as to realize the pre-winding of the winding needle 100 on the diaphragm; then, inserting the positive pole piece and the negative pole piece into the diaphragm, and winding the diaphragm by a winding needle 100 to form a battery cell; after the battery core is formed, the positive electrode plate and the negative electrode plate are firstly cut and rolled into the battery core, and the diaphragm is used for wrapping the periphery of the battery core (in other embodiments, the positive electrode plate and the diaphragm may be firstly cut and ended by the negative electrode plate, which is not described herein again); cutting the diaphragm after reserving the diaphragm to be ended; the revolution mechanism 400 drives the winding needle 100 to revolve until the winding needle 100 at the winding station reaches the blanking station, and at the moment, the winding needle 100 is at the working station corresponding to the blanking station; the winding driving member 520 drives the third link member 510 to rotate, so as to drive the second link member 110 and the winding needle 100 to rotate, thereby realizing the ending of the diaphragm; after the cell ending part is fixed by other equipment (not shown), the cell is clamped by blanking equipment (not shown); the plugging mechanism 200 drives the winding needle 100 to be recovered to the avoiding station; the blanking equipment transfers the battery cell; the revolution mechanism 400 drives the winding needle 100 to revolve, and the winding needle 100 at the blanking station returns to the winding station to prepare for starting a new round of cell winding.

In order to facilitate the winding station, when the plugging mechanism 200 drives the winding needle 100 to extend to the working station, the winding needle 100 can clamp a diaphragm to be pre-wound, and the winding needle 100 needs to be reset after the electrical element is blanked, so that the winding needle 100 is in a fixed state; in this state, the winding needle 100 can directly grip the diaphragm when it is extended to the working station at the winding station.

Specifically, the winding needle 100 has two openable and closable flaps, and the two flaps of the winding needle 100 can be opened or closed under the driving of the opening and closing driving member 120, thereby clamping or releasing the substrate (releasing the clamped diaphragm during blanking to facilitate the extraction of the winding needle 100). Referring to fig. 4, the septum is a straight line arranged in the up-down direction illustrating the middle of the two-piece curling needle 100. When the winding needle 100 is in a fixed state, the gap between two sections of the opened winding needle 100 is opposite to the diaphragm, the plugging mechanism 200 drives the winding needle 100 to extend out to a working station, the diaphragm enters the gap, the opening and closing driving piece 120 drives the winding needle 100 to close, the diaphragm is clamped, and the winding needle 100 can rotate with the diaphragm conveniently.

Therefore, at the discharging station, the positioning detection piece 530 detects the mark on the winding needle 100, so that the current state of the winding needle 100 can be confirmed, and the winding needle 100 is convenient to reset to a fixed state.

In one embodiment, the mark on the winding needle 100 is a slot formed in a clip 550, and the positioning detector 530 is a photoelectric sensor. The clip 550 is disposed at the end of the winding needle 100 and can rotate and revolve with the winding needle 100. After the electrical element is blanked, the positioning detection piece 530 detects the clamping piece 550; at this time, the winding needle 100 starts to rotate until the positioning detection part 530 detects the gap on the clip 550; the winding needle 100 stops rotating, and the winding needle 100 is in a fixed state. It is easy to understand that the detecting end of the positioning detecting member 530 faces the clip 550, and the clip 550 will cover the signal of the positioning detecting member 530 until the gap occurs, and the signal can pass through the clip 550, so as to detect the predetermined position. At this time, the fixed state of the winding needle 100, that is, the position where the positioning detector 530 detects the gap, is set; after the positioning detecting member 530 detects the occurrence of the gap, the information is transmitted to the control system, and the control system controls the winding needle 100 to stop rotating, so that the winding needle 100 is in a fixed state.

More specifically, at this time, the rotation of the winding needle 100 may depend on the winding mechanism 500. That is to say, after the electrical component is blanked, the plugging mechanism 200 drives the winding needle 100 to extend to the working station, so that the second linkage member 110 arranged on the winding needle 100 can contact with the third linkage member 510 of the winding mechanism 500, and linkage is realized. Alternatively, a reset mechanism (not shown) may be provided, which is provided near the avoiding position, and when the winding needle 100 is pulled out from the electric component and is in the recovery state, the reset mechanism can adjust the position state of the winding needle 100 by engaging with the positioning detector 530. The mechanism of the reset mechanism is similar to the winding mechanism 500, and is not described herein. Of course, the resetting mechanism may be disposed near the avoiding station of the discharging station, or may be disposed near the avoiding station of the winding station, as long as the resetting of the winding needle 100 can be completed before the winding needle 100 starts a new winding round.

In other embodiments, the mark provided on the winding needle 100 may have other structures according to the configuration of the positioning detecting member 530, so long as the positioning detecting member 530 can detect the mark.

As will be readily appreciated, in order to enable the air supply block 620 and the connection block 610 to move relatively and abut against each other, the air supply driving assembly 630 may be connected to the air supply block 620 to drive the air supply block 620 to move towards the connection block 610; the air supply driving unit 630 may also be connected to the connection block 610 to drive the connection block 610 to move toward the air supply block 620.

The air cylinder comprises a driving component 210 for driving the winding needle 100 to extend out or retract, and/or an opening and closing driving component 120 for driving the winding needle 100 to open or close.

In order to realize air supply, an air outlet hole 611 is formed in the connecting block 610, one end of the air outlet hole 611 is communicated with the air cylinder, and the other end of the air outlet hole 611 is arranged towards the air supply block 620; an air inlet hole 621 is formed in the air supply block 620, one end of the air inlet hole 621 is communicated with an air supply device, and the other end of the air inlet hole 621 faces the air outlet hole 611; when the air supply block 620 abuts against the connection block 610, the air inlet hole 621 communicates with the air outlet hole 611, thereby achieving the circulation of the air flow.

Wherein, according to the number of cylinders that the connecting block 610 needs to connect, the connecting block 610 may be provided with a plurality of sets of air outlets 611. The air holes 611 are communicated with the corresponding air cylinders through air pipes. At this time, the air supply block 620 may have a plurality of air inlets 621 corresponding to the air holes 611, so as to ensure independent air supply and ensure accurate operation of the air cylinders.

Referring to fig. 2 and 3, the air outlet hole 611 and the air inlet hole 621 are disposed opposite to each other; after the air supply block 620 abuts against the connecting block 610, the air outlet hole 611 and the air inlet hole 621 form a communicated channel to realize the circulation of air flow.

Further, the air supply mechanism 600 further comprises a positioning component 640 for defining the position of the air supply block 620 abutting against the connecting block 610, and ensuring that the air inlet hole 621 is in direct contact with the air outlet hole 611.

It is easy to understand that if the air outlet hole 611 and the air inlet hole 621 are not aligned, the air flow rate may be affected, and thus the precision of the cylinder movement is affected, and the accuracy of the motion of the winding needle 100 is affected. From this, set up locating component 640, when air feed block 620 supports and leans on connecting block 610, guarantee that air feed block 620 supports and leans on preset fixed position, and at this moment, air outlet 611 aligns inlet 621.

In one embodiment, the positioning component 640 can be a limiting block; for example, a protruding fence is provided on the outer periphery of the connection block 610 or the air supply block 620, so that when the two abut against each other, one without the fence protrudes into the fence to abut against the other, and the position where the two abut against each other is defined by the fence.

In other embodiments, a structure of inserting and matching can be arranged; for example, set up mutually supporting recess and lug on connecting block 610 and air feed block 620 for when the two leaned on, the lug stretched into in the recess, and then guaranteed that the two leaned on in predetermined fixed position.

Alternatively, the positioning assembly 640 comprises a positioning hole 641 formed in the connecting block 610 and a positioning pin 642 arranged on the air supply block 620, or the positioning assembly 640 comprises a positioning hole 641 formed in the air supply block 620 and a positioning pin 642 arranged on the connecting block 610; when the air supply block 620 abuts against the connection block 610, the positioning pin 642 is inserted into the positioning hole 641.

The positioning hole 641 and the positioning pin 642 are fitting components with high positioning accuracy, and by limiting that the positioning pin 642 can only be inserted into the positioning hole 641, the connecting block 610 and the gas supply block 620 can be ensured to abut against each other at a predetermined fixed position. Of course, if the connecting block 610 and the air supply block 620 have a large structure, a plurality of sets of positioning pins 642 and positioning holes 641 may be provided on the surfaces of the connecting block and the air supply block that contact each other.

Further, the air supply mechanism 600 further includes a sealing member 650, the sealing member 650 being disposed between the connection block 610 and the air supply block 620, the sealing member 650 being capable of sealing the air inlet hole 621 and the air outlet hole 611 when the air supply block 620 abuts against the connection block 610.

It will be readily appreciated that the connection block 610 and the gas supply block 620 are separate pieces that, when abutted, cannot be completely airtight. If leak gas, can influence the air current flow, and then influence the precision of cylinder motion, influence the accuracy of rolling up needle 100 action. Thus, the air inlet hole 621 and the air outlet hole 611 are sealed by the sealing member 650, and the stable flow of the air can be ensured.

Wherein, the sealing element 650 can be a ring-shaped rubber pad, and the rubber pad is arranged at the periphery of the air inlet hole 621 or the air outlet hole 611; when the air supply block 620 abuts against the connecting block 610, the rubber pad is compressed between the air supply block 620 and the connecting block 610, and a sealing effect can be achieved.

To ensure the stability of the movement of the air supply block 620, the air supply driving assembly 630 includes an air supply driving part 631 and an air supply guiding part 632; the air supply guide 632 is extended toward the connection block 610; the air supply block 620 is slidably connected with the air supply guide 632; the air supply actuator 631 may drive the air supply block 620 to move along the air supply guide 632.

The air supply driving part 631 may be a driving member such as an air cylinder and a motor; air supply guide 632 may be a guide member such as a guide bar, a guide rail, or the like.

It should be explained that, for the multi-station winding machine provided by the present application, each set of winding needles 100 needs to revolve around, so that each winding needle 100 is located at a different station to perform different stages of electric component preparation work; during revolution, the winding needles 100 and the plugging mechanisms 200 corresponding to the winding needles 100 one by one synchronously change the working positions. On the other hand, in order to supply air to the air cylinder so that the inserting/extracting actuator 210 and/or the opening/closing actuator 120 can drive the winding needle 100 to operate, the air cylinder needs to be connected to an external air supply device (not shown) through an air pipe. In this case, the winding needle 100 revolves, and in order to prevent the dislocation of the air tube, the air tube and the air supply device need to revolve along with it, which is very inconvenient. Thus, the present application provides a split air supply method that can prevent the air supply device from revolving with the winding needle 100.

Referring specifically to fig. 2, in an embodiment, the winding machine includes two sets of winding needles 100, and the revolving mechanism 400 is configured to drive the winding needles 100 to revolve, such that one set of winding needles 100 is at the winding station, and the other set of winding needles 100 is at the discharging station.

At this time, the winding machine further comprises two groups of air supply mechanisms 600, the connecting blocks 610 of the two groups of air supply mechanisms 600 are respectively and correspondingly connected with one group of winding needles 100, the connecting blocks 610 of the two groups of air supply mechanisms 600 are relatively and fixedly arranged with the corresponding winding needles 100, and when the revolution mechanism 400 drives the winding needles 100 to revolve, the connecting blocks 610 and the winding needles 100 synchronously revolve; the air supply block 620 and the air supply driving assembly 630 of one set of air supply mechanism 600 are arranged at the winding station, and the air supply block 620 and the air supply driving assembly 630 of the other set of air supply mechanism 600 are arranged at the blanking station.

The revolution mechanism 400 further includes a rotating disc 430 on the rotating shaft 410, the winding needle 100 is disposed on the rotating shaft 410, the connecting block 610 is disposed on the rotating disc 430, and the revolution driving member 420 drives the rotating shaft 410 and the rotating disc 430 thereon to rotate, and drives the winding needle 100 and the connecting block 610 to revolve synchronously. It is easy to understand that when the winding needle 100 is inserted and pulled, the winding needle moves to the working station or the avoiding station along the axial direction of the rotating shaft 410, if the connecting block 610 is inserted and pulled along with the rotating shaft, after the air supply block 620 abuts against the connecting block 610, the connecting block 610 is separated from the air supply block 620, the air supply is cut off, and the re-action of the winding needle 100 is influenced; therefore, the connection block 610 needs to be relatively fixedly disposed on the rotation shaft 410. Meanwhile, through the arrangement of the rotating disc 430, the mutual interference of each group of connecting blocks 610, the connecting blocks 610 and the air pipes of the air cylinders can be further avoided.

In summary, when the winding needle 100 and the inserting and extracting mechanism 200 corresponding to the winding needle 100 are revolved and synchronously switched between the stations, the rotating disc 430 and the connecting block 610 arranged on the rotating disc 430 and corresponding to the winding needle 100 revolve synchronously with the same, and the air supply block 620, the air supply driving assembly 630 and the air supply device are fixedly arranged near the winding station and the blanking station without revolving. In the revolution process, the winding needle 100 does not need to do other actions, so that the air cylinder driving the winding needle 100 to act is not connected with an air supply device and can not act, and the operation of the device is not influenced. When the winding needle 100 revolves in place, before the winding needle 100 needs to be inserted, pulled out and/or opened and closed, the air supply driving assembly 630 drives the air supply block 620 to abut against the connecting block 610, so that the air supply device can supply air to the inserting and pulling driving piece 210 and/or the opening and closing driving piece 120 through the air supply block 620 and the connecting block 610, and the action of the winding needle 100 is realized.

Of course, except for the air cylinder for driving the winding needle 100 to move, there may be other air cylinders for driving other mechanisms to move and simultaneously needing to revolve with the winding needle 100, air supply can be realized through the air supply mechanism 600, only a plurality of air outlets 611 are required to be formed in the air supply block 620 to be communicated with the air cylinder, and the application is not limited.

Such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
