The first embodiment:
referring to fig. 1, fig. 1 is a schematic structural diagram of a cell winding device 10 applied to a cell production system 100 according to a first embodiment of the present invention.
A first embodiment of the present invention provides a cell winding device 10, where the cell winding device 10 has characteristics of being capable of continuously conveying a separator 910, and having high winding efficiency and high winding quality. The cell winding device 10 can be applied to a battery production apparatus, a battery production line, or the like, and of course, the cell winding device 10 can be used independently.
Taking the application of the cell winding device 10 to a battery production device as an example, the cell production system 100 includes the cell winding device 10, and the core 900 is formed by winding the cell winding device 10, of course, the cell production system 100 may further include a production conveying mechanism 20, where the production conveying mechanism 20 is disposed near the cell winding device 10 and is configured to receive the core 900 formed by winding the cell winding device 10, so as to convey the core outward, and of course, the production conveying mechanism 20 may also convey the diaphragm 910 or the pole piece 920 to the cell winding device 10.
Since the cell production system 100 employs the cell winding device 10 according to the first embodiment of the present invention, the cell production system 100 also has the characteristics of being capable of continuously conveying the separator 910, and having high winding efficiency and high winding quality.
The structural composition, the operation principle and the beneficial effects of the cell winding device 10 according to the first embodiment of the present invention will be described in detail below.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a cell winding device 10 according to a first embodiment of the present invention. The direction of the arrow on the winding path 121 in fig. 2 is the direction of the winding mechanism 151 moving along the winding path 121.
The cell winding device 10 includes a mounting platform 12, a conveying assembly 13, and a winding assembly 15, the winding assembly 15 includes a plurality of winding mechanisms 151, an annular winding path 121 is provided on the mounting platform 12, and, the winding path 121 has a path named a shift section 122, the shift section 122 is disposed along a straight line, one end of the shift section 122 is a winding station 125, the conveying assembly 13 is mounted on the mounting platform 12, and the transport assembly 13 is used to transport the membrane 910 and the pole piece 920 to the winding station 125, to facilitate winding of the separator 910 and the pole piece 920 by the winding mechanism 151 at the winding station 125 to form the winding core 900, and the conveying direction of the conveying assembly 13 is the same direction and is collinear with the extending direction of one end of the index section 122 far away from the winding station 125, alternatively, the direction of the transport pole piece 920 and the membrane 910 of the transport assembly 13 is collinear with the length of the winding station 125 and is directed along the winding station 125 toward the other end of the winding path 121.
The winding mechanisms 151 are movably connected to the mounting platform 12, and the winding mechanisms 151 are capable of moving along the winding path 121. The winding mechanism 151 is able to receive the membrane 910 and the pole piece 920 at the winding station 125 and wind the membrane 910 and the pole piece 920 to form the winding core 900, and, when forming the winding core 900, the corresponding winding mechanism 151 leaves the winding station 125 along the index section 122; so that another winding mechanism 151 enters the winding station 125 to continue winding another winding core 900, and when one winding mechanism 151 leaves the winding station 125, the other winding mechanism 151 can move to the winding station 125 while cutting the separator 910 at the end of the previous winding core 900 and while receiving the separator 910 to drive the separator 910 to continue winding.
Thus, when one winding mechanism 151 winds to form the winding core 900 and leaves the winding station 125 along the shifting section 122, the other winding mechanism 151 immediately enters the winding station 125 and receives and continues to wind the membrane 910, so that the conveying mechanism can continuously convey the membrane 910 outwards, large tension fluctuation is not easy to occur on the membrane 910, deviation and the like are not easy to occur on the membrane 910 in the winding process, the winding quality of the winding core 900 is improved, the shifting section 122 has the same conveying direction as the conveying assembly 13, when the winding mechanism 151 winds to form the winding core 900 and leaves the winding station 125 along the shifting section 122, the membrane 910 is spread at the winding station 125, the process of leaving the winding station 125 has little influence on the conveying assembly 13 to convey the membrane 910, and the other winding mechanism 151 is convenient to receive the membrane 910; in addition, the winding mechanism 151 receives the separator 910 and cuts the separator 910, so that the auxiliary time is reduced, and the plurality of winding mechanisms 151 sequentially enter the winding station 125 to perform winding operation, so that the winding efficiency of the cell winding device 10 is improved.
It should be noted that the movement speed of the winding mechanism 151 away from the winding station 125 along the index section 122 may be equal to the transfer speed of the transfer assembly 13 for transferring the separator 910, or alternatively, the transfer assembly 13 continuously transfers the separator 910 at a constant speed during the winding of the winding mechanism 151 to form the core 900 and away from the winding station 125, and the movement speed of the winding mechanism 151 is equal to the movement speed of the separator 910, so as to stably unwind the separator 910 from the winding station 125, further reduce the influence of the process of the winding mechanism 151 leaving the winding station 125 on the transfer assembly 13 for transferring the separator 910, and further facilitate the subsequent winding mechanism 151 entering the winding station 125 for receiving the separator 910.
Further, the winding mechanism 151 may include a winding needle 1511 and a winding driving member 1515, the winding driving member 1515 is slidably connected to the mounting platform 12 and can drive the winding needle 1511 to move along the winding path 121, wherein the winding needle 1511 is used for clamping the membrane 910 to complete the action of receiving the membrane 910, the winding needle 1511 can also be driven by the winding driving member 1515 to rotate to complete the action of winding the membrane 910, the conveying assembly 13 can also convey the pole piece 920 to the winding needle 1511 while the winding needle 1511 winds the membrane 910 to form the winding core 900 by winding the membrane 910 and the pole piece 920, so that the membrane 910 pause is reduced, the phenomenon that tension waves are brought to the membrane 910 due to the pause of the membrane 910 when the winding is started is avoided, and the quality of the winding core 900 is further improved.
The conventional winding method needs to wind a part of the membrane 910 at the beginning to complete the pre-winding operation, and stop the winding after completing the pre-winding operation, and continue the winding after pressing in the pole piece 920, which may cause tension fluctuation on the membrane 910 due to the stopping operation after pre-winding the membrane 910, and affect the quality of the winding core 900.
It should be noted that the winding driving member 1515 may be a driving mechanism such as a belt, etc., which is connected with a plurality of winding needles 1511 and arranged along the winding path 121 to drive the winding needles 1511 to move along the winding path 121, the winding driving member 1515 may also be a mechanical arm connected to the mounting platform 12, etc., furthermore, the winding needle 1511 may include a driving portion (not shown) composed of two half needles 1512, and the two half needles 1512 are connected to the driving portion of the winding needle 1511 to drive the two half needles 1512 to clamp the membrane 910 through the driving portion.

In the conventional disc type winding head, the mechanism for cutting off the diaphragm 910 is arranged separately from the winding head, the distance from the stroke of the diaphragm 910 is long, the time required for cutting off the diaphragm 910 is long, the winding cutting knife 1513 of the cell winding device 10 is directly arranged inside the winding needle 1511, and the diaphragm 910 is cut off while being clamped, so that the auxiliary time is further reduced, and the efficiency of the cell winding device 10 is improved.
It should be noted that, when the winding mechanism 151 enters the winding station 125, it can also move in the winding station 125 along the direction extending from the end of the index section 122 far from the winding station 125, and the moving speed is equal to the speed of the conveying assembly 13 for conveying the membrane 910. Or, in the process that the winding mechanism 151 enters the winding station 125 to receive and cut the membrane 910, the winding mechanism 151 also moves along the conveying direction of the membrane 910, and the movement speeds of the winding mechanism 151 and the membrane 910 are the same, so that the winding needle 1511 and the membrane 910 are relatively static, the actions of the winding needle 1511 for clamping the membrane 910 and the winding cutting knife 1513 for cutting the membrane 910 do not affect the conveying of the membrane 910, the influence of clamping the membrane 910 and cutting the membrane 910 on the conveying of the membrane 910 is reduced, the fluctuation of the membrane 910 is reduced, and the quality of the winding core 900 is further improved.

The diaphragm 910 and the pole piece 920 are conveyed by the conveying roller 131 to ensure that the respective tensions of the diaphragm 910 and the pole piece 920 are balanced, and the winding quality is further improved.
It should be noted that the conveying roller 131 is formed by combining two oppositely disposed rollers, and in other embodiments, the conveying roller 131 may also be another transmission mechanism, such as a conveying mechanism formed by two adjacently disposed conveying belts.
Further, the conveying assembly 13 may further include a cutting mechanism 135, the cutting mechanism 135 includes a conveying cutting blade 1351 and a cutting driving member 1352, the cutting driving member 1352 is slidably connected to the mounting platform 12, and the cutting driving member 1352 can drive the conveying cutting blade 1351 to move along the conveying direction of the pole piece 920.
When the length of the pole piece 920 wound by the winding needle 1511 is the first preset length, the conveying cutting knife 1351 can move along the conveying direction of the pole piece 920 and cut off the pole piece 920 under the driving of the cutting driving member 1352, so that the length of the pole piece 920 on the winding core 900 is the first preset length. Thus, when the pole piece 920 is cut, the transmission of the diaphragm 910 and the pole piece 920 does not need to be stopped, the auxiliary time is further reduced, the pause caused by cutting the pole piece 920 is reduced, and the efficiency of the cell winding device 10 is improved.
The conventional winding machine needs to clamp the pole piece 920 and then cut off after winding the pole piece 920, so that the auxiliary time is long, and the conveying of the diaphragm 910 needs to be stopped.
When the winding mechanism 151 located at the winding station 125 winds the winding core 900 to form the winding core, the pole piece transfer mechanism 132 transfers the pole piece 920 to the transfer roller 131 so that the pole piece 920 is close to the transfer roller 131, so that when the winding mechanism 151 located at the winding station 125 starts to wind the separator 910, the pole piece transfer mechanism 132 can transfer the pole piece 920 to the transfer roller 131 relatively quickly.
Further, the winding assembly 15 may further include a gluing mechanism 152, the gluing mechanism 152 is mounted on the mounting platform 12, the winding path 121 is further provided with a gluing station 126, the gluing mechanism 152 is disposed near the gluing station 126, and the gluing mechanism 152 is configured to glue the winding core 900 when the winding mechanism 151 moves to the gluing station 126, so that the winding mechanism 151 can move to the gluing station 126 along the winding path 121 to perform a gluing operation when the winding mechanism 151 winds the winding station 125 to form the winding core 900.
In this way, by providing a plurality of winding mechanisms 151 that are movable relative to the mounting platform 12, the winding operation and the taping operation of each winding mechanism 151 are performed independently, and the overall winding efficiency of the cell winding device 10 is improved. When the disc structure of the existing winding device is in a station changing state, the auxiliary actions of other winding cores 900 on the disc structure cannot be performed synchronously, the corresponding actions of all the winding cores 900 need to be started and stopped, and the whole winding efficiency is low.
It should be noted that the taping operation involves pressing the core 900 on the needle 1511 and applying glue to the end of the membrane 910 of the core 900 to ensure that the core 900 does not loosen.
Further, the winding assembly 15 may further include a discharging mechanism 153, the discharging mechanism 153 is installed on the mounting platform 12, and a discharging station 127 is further disposed on the winding path 121, the discharging mechanism 153 is disposed near the discharging station 127, and is configured to receive the winding core 900 when the winding mechanism 151 moves to the discharging station 127, so as to place the winding core 900 onto the production conveying mechanism 20, and further improve the overall winding efficiency of the cell winding device 10.
It should be noted that the blanking mechanism 153 may be a moving mechanism such as a manipulator, etc. to remove the winding core 900 on the winding needle 1511, in this embodiment, the winding station 125, the rubberizing station 126, and the blanking station 127 are sequentially disposed in the shift section 122 along the conveying direction of the conveying mechanism, the winding mechanism 151 may move to the rubberizing station 126 to perform rubberizing when the winding station 125 forms the winding core 900, move to the blanking station 127 to perform blanking to place the winding core 900 on the production conveying mechanism 20, and the winding mechanism 151 moves along the winding path 121 again, and enters the winding station 125 to continue winding when the previous winding mechanism 151 leaves the winding station 125.

next, the winding needle 1511 of the other winding mechanism 151 moves to the winding station 125, the winding needle 1511 sandwiches the separator 910, and while sandwiching the separator 910, the winding cutting blade 1513 cuts the end of the separator 910 of the core 900 on the preceding winding mechanism 151 so as to wind the separator 910 on the winding needle 1511 of the winding station 125, and while the actions of the winding needle 1511 sandwiching the separator 910 and the winding cutting blade 1513 cutting the separator 910 proceed, the winding needle 1511 and the winding cutting blade 1513 both move together with the separator 910 at the same movement speed, and further, while starting winding the separator 910, the pole piece transfer mechanism 132 transfers the pole piece 920 to the transfer roller 131 so that the winding needle 1511 winds the separator 910 and the pole piece 920.
The winding mechanism 151 located at the winding station 125 continues to wind, and when the winding needle 1511 is about to wind the pole piece 920 with the first preset length, the conveying cutting knife 1351 is driven by the cutting driving member 1352 to move along the conveying direction of the pole piece 920 and cut off the pole piece 920, so that the length of the pole piece 920 on the winding core 900 is the first preset length, and the speed of the conveying cutting knife 1351 moving along the conveying direction of the pole piece 920 is equal to the conveying speed of the pole piece 920;

To sum up:
the first embodiment of the present invention provides a cell winding device 10, which has the characteristics of being capable of continuously conveying a separator 910, and having high winding efficiency and high winding quality.
Second embodiment:
referring to fig. 3, fig. 3 is a schematic flow chart of a cell winding method according to a second embodiment of the present invention.
The basic principle and the technical effects of the cell winding device 10 are the same as those of the above embodiments, and for the sake of brief description, no part of this embodiment is mentioned, and reference may be made to the corresponding contents in the above embodiments.
The cell winding method comprises the following steps:
step S101: the winding mechanism 151 moves to the winding station 125 as the previous winding mechanism 151 leaves the winding station 125, severs the separator 910 at the end of the winding core 900 on the previous winding mechanism 151, and receives and winds the separator 910.
In this way, after the previous winding mechanism 151 winds the winding core 900 and leaves the winding station 125, the previous winding mechanism enters the winding station 125 to perform the winding operation, so that the conveying assembly 13 can continuously convey the separator 910 to the winding station 125, the pause of the separator 910 is reduced, the winding quality of the winding core 900 is improved, and the winding mechanism 151 cuts the separator 910 while receiving the separator 910, the auxiliary time is reduced, and the winding efficiency of the cell winding device 10 is improved.
It should be noted that in the present embodiment, the action of the winding mechanism 151 exiting the winding station 125 and the action of the other winding mechanism 151 entering the winding mechanism 151 are synchronized to ensure that the transfer assembly 13 outputs the membrane 910 at a constant speed; in other embodiments, the two actions may be in tandem so that the delivery assembly 13 can continuously deliver the membrane 910 without stopping the membrane 910.
Further, in step S101, the action of the winding mechanism 151 receiving the separator 910 may be accomplished by the winding needle 1511 gripping the separator 910, and at the same time, the action of cutting the separator 910 may be accomplished by the winding cutting blade 1513 cutting the separator 910 at the end of the core 900 on the winding mechanism 151 leaving the winding station 125 while the winding needle 1511 grips the separator 910. So as to improve the speed of cutting the diaphragm 910, further reduce the auxiliary time, and improve the efficiency of the cell winding device 10.
Furthermore, during the movement of winding mechanism 151 to winding station 125, winding mechanism 151 may move on winding station 125 in a direction extending from the end of index section 122 remote from winding station 125 as it enters winding station 125, and at a speed equal to the speed at which transfer assembly 13 transfers diaphragm 910. Or, in the process that the winding mechanism 151 enters the winding station 125 to receive and cut the membrane 910, the winding mechanism 151 also moves along the conveying direction of the membrane 910, and the movement speeds of the winding mechanism 151 and the membrane 910 are the same, so that the winding needle 1511 and the membrane 910 are relatively static, the actions of the winding needle 1511 for clamping the membrane 910 and the winding cutting knife 1513 for cutting the membrane 910 do not affect the conveying of the membrane 910, the influence of clamping the membrane 910 and cutting the membrane 910 on the conveying of the membrane 910 is reduced, the fluctuation of the membrane 910 is further reduced, and the quality of the winding core 900 is improved.
Further, after step S101, the method further includes:
step S102: the conveying cutting blade 1351 moves along the conveying direction of the pole piece 920 and cuts the pole piece 920, so that the length of the pole piece 920 on the winding core 900 is a first preset length.
Or, when the winding mechanism 151 at the winding station 125 is about to wind the pole piece 920 with the first preset length, the conveying cutting knife 1351 is driven by the cutting driving member 1352 to move along the conveying direction of the pole piece 920 and cut off the pole piece 920, so that the length of the pole piece 920 on the winding core 900 is the first preset length. Therefore, when the pole piece 920 is cut, the transmission of the diaphragm 910 and the pole piece 920 does not need to be stopped, the pause caused by cutting the pole piece 920 is reduced, the conveying assembly 13 is kept to continuously convey the diaphragm 910, the auxiliary time is further reduced, and the efficiency of the cell winding device 10 is improved.
It should be noted that, in step S102, the conveying cutting blade 1351 can also move at the conveying speed of the pole piece 920 driven by the cutting driving member 1352, so that the pole piece 920 and the conveying cutting blade 1351 are relatively stationary, so that the movement of the cutting pole piece 920 does not affect the conveying of the diaphragm 910, the conveying assembly 13 can convey the diaphragm 910 at a constant speed, the fluctuation of the diaphragm 910 is further reduced, and the quality of the winding core 900 is improved.
Further, after step S102, the cell winding method further includes:
step S103: the winding mechanism 151 exits the winding station 125 along the index segment 122 as it winds to form the core 900.
It should be noted that the speed of movement of the winding mechanism 151 along the index section 122 away from the winding station 125 may be equal to the speed of the transfer assembly 13 transferring the film 910. Alternatively, the transfer module 13 continuously transfers the membrane 910 at a constant speed during the winding of the winding mechanism 151 to form the winding core 900 and leaves the winding station 125, while the winding mechanism 151 moves at a speed equal to the speed of the membrane 910 to stably unwind the membrane 910 from the winding station 125, to reduce the effect of the process of leaving the winding station 125 by the winding mechanism 151 on the transfer module 13 to transfer the membrane 910, and to facilitate the receiving of the membrane 910 at the winding station 125 by the following winding mechanism 151.
Further, after step S103, the cell winding method further includes:
step S104:
step S104: the winding mechanism 151 moves to the rubberizing station 126 along the transposition section 122, and the rubberizing mechanism 152 performs rubberizing operation on the winding core 900 on the winding mechanism 151;
step S105: the winding mechanism 151 moves to the blanking station 127 along the transposition section 122, and the blanking mechanism 153 performs blanking operation on the winding core 900 on the winding mechanism 151 so as to place the winding core 900 on the production conveying mechanism 20;
step S106: the winding mechanism 151 continues to move along the winding path 121; to continue to perform step S101.
In this way, by providing a plurality of winding mechanisms 151 that are movable relative to the mounting platform 12, the winding operation, the gluing operation, and the blanking operation of each winding mechanism 151 are performed independently, and the overall winding efficiency of the cell winding device 10 is improved.
The working principle of the cell winding method provided by the second embodiment of the invention is as follows:
the winding mechanism 151 enters the winding station 125 when the previous winding mechanism 151 leaves the winding station 125, cuts off the membrane 910 at the end of the winding core 900 on the previous winding mechanism 151, receives and winds the membrane 910, clamps the membrane 910 by the winding needle 1511, and simultaneously clamps the membrane 910, the winding cutting knife 1513 cuts off the end of the membrane 910 of the winding core 900 on the previous winding mechanism 151, and when the action of clamping the membrane 910 by the winding needle 1511 and cutting the membrane 910 by the winding cutting knife 1513 is carried out, the winding needle 1511 and the winding cutting knife 1513 both move together with the membrane 910 to keep the conveying assembly 13 conveying the membrane 910 at a constant speed;
the conveying cutting knife 1351 moves along the conveying direction of the pole piece 920 and cuts off the pole piece 920, so that the length of the pole piece 920 on the winding core 900 is a first preset length, and the moving speed of the conveying cutting knife 1351 is the same as the conveying speed of the pole piece 920;
the winding mechanism 151 leaves the winding station 125 along the index section 122 when winding the core 900, and the winding mechanism 151 leaves the winding station 125 along the index section 122 at a speed equal to the transfer speed of the transfer assembly 13 for transferring the membrane 910, so as to further keep the transfer assembly 13 transferring the membrane 910 at a constant speed;
the winding mechanism 151 moves to the rubberizing station 126 and the blanking station 127 along the winding path 121 in sequence, continues to move along the winding path 121 after the rubberizing operation and the blanking operation are completed, and continues to enter the winding station 125 for winding operation.
