Description

Active cache method and device, storage medium and continuous winding machine

Technical Field

The invention relates to the technical field of lithium battery production, in particular to a winding technology of a battery.

Background

In the lithium battery manufacturing industry, the lithium battery winding equipment winds a pole piece and a diaphragm together to form a battery core, and then a lithium battery finished product is manufactured after a series of processes such as hot pressing, tab welding, liquid injection and the like. The core process of the lithium battery manufacturing is cell winding, and the performance of the lithium battery is directly determined by the quality of the cell winding. The existing winding equipment adopts a continuous winding production mode in order to improve the production efficiency, and a continuous winding machine generally comprises an unwinding mechanism, a buffer mechanism and a winding mechanism, wherein the number of the winding mechanism is more than two, and the winding mechanism comprises a turntable and more than two groups of winding needles. Through add buffer memory mechanism before the rolling, when the winding mechanism switches the station operation, can buffer memory pole piece and diaphragm, avoid pole piece and diaphragm to continuously get into the winding mechanism, after switching the station and accomplish, buffer memory mechanism releases the material and rolls up for material is rolled up and is entered into winding mechanism again, has avoided the condition that the supplied materials shut down, thereby has realized continuous coiling, has shortened the assistance-time, has promoted holistic coiling efficiency.

However, in the preparation process of the existing winding equipment, a buffer mechanism basically adopts a passive buffer mechanism, and aims at the situation that a small diaphragm tension control is involved in part of processes, when a rotary table is used for changing stations at a high speed, the buffer mechanism needs to overcome the acceleration inertia of a diaphragm passing through a roller, a tension swing rod in the buffer mechanism is easily pulled to a large extent, and even the tension swing rod directly reaches the limit position to trigger an alarm. The stability of the equipment is seriously influenced, and the quality problems of the electric cores such as membrane dislocation and the like are easily caused.

Disclosure of Invention

The present invention is directed to solving at least one of the problems of the prior art. Therefore, the invention provides an active cache method, an active cache device, a storage medium and a continuous winding machine.

The solution of the invention for solving the technical problem is as follows:

in one aspect, an embodiment of the present invention includes an active buffering method for a continuous winding apparatus, where the continuous winding apparatus includes an active buffering mechanism and a turntable, the active buffering mechanism includes a driving motor, and the turntable includes a flipping motor, and the method includes:

an electronic cam is generated by designing or acquiring a cam curve of the position relation between a driving motor and a turnover motor;

before the turntable is switched to the station, the electronic cam is coupled;

and when the rotary table changes the station, the active buffer mechanism synchronously releases the buffered material roll.

The invention has the beneficial effects that:

according to the active caching method provided by the invention, when the continuous winding equipment is in a high-speed station changing process, the electronic cam is used for controlling the active caching mechanism to actively and synchronously release stored materials, so that the station changing process is realized, most of the rolls do not need to be accelerated, the violent amplitude of the unwinding swing rod is reduced, the tension fluctuation of a material roll in the station changing process is reduced, and the risk of alarming caused by dislocation of the material roll and the situation that the unwinding cache of the material roll reaches a limit position is reduced.

As a further improvement of the technical scheme, before the rotary table is changed, whether each station is finished or not is judged, and the station is allowed to be changed. Because the driving motor and the overturning motor need to work simultaneously when the station is changed, if other parts are not prepared in a high-speed state, the production is abnormal.

As a further improvement of the technical scheme, after the turntable is in place at the station changing position, the driving motor is driven to act and reset. When the turntable is in place, the active caching mechanism acts to reset, the material roll is temporarily stored in the active caching mechanism again for preparing the next release, and meanwhile, the active caching mechanism and the unwinding mechanism can be synchronously controlled by using the same principle when the turntable is reset, so that the tension of the diaphragm is stable when the turntable is reset.

In the process of station changing, how the active cache is matched with the speed of the synchronous turntable is a difficult point to control, and in the control method, an electronic cam is generated by designing or acquiring a position relation cam curve of an active cache driving motor and a station changing driving motor; the electronic cam is coupled before the station is changed, so that synchronous control is realized. And as for the generation mode of the electronic cam coupled by the driving motor and the overturning motor, the following steps can be adopted:

fixing a material roll at a feeding position of the active buffer mechanism;

switching a control mode of the driving motor to a reading mode;

executing slow station changing action, and simultaneously acquiring corresponding relation data of the position of the turnover motor and the position of the driving motor;

after the station is changed, the data acquisition work is finished, and the acquired data is transmitted to the electronic cam meter to be used as stroke ratio data of the electronic cam;

and generating an electronic cam according to the generated stroke ratio data by using a PLC electronic cam related command.

The electronic cam adopts a self-learning mode, the work station is slowly changed, and the corresponding stroke ratio data of the electronic cam (for example, the work station changing position information is main shaft data, and the active cache position information is slave shaft data) is produced by reading the position corresponding relation of the two motors in the work station changing process. The desired electronic cam is then generated. Then, when the machine works formally, due to the existence of the electronic cam, the releasing speed of the material roll cached actively is basically and completely matched with the speed of the turntable, the violent amplitude of the unreeling swing rod is effectively reduced, and the tension fluctuation of the material roll in the process of station changing is reduced.

As a further improvement of the technical scheme, before the self-learning is carried out, the unwinding tension of the material roll is reduced. Therefore, the pulling deformation of the material roll can be reduced, and the accuracy of reading data is improved.

In addition to the "self-learning" method described above, the electronic cam may be generated as follows:

establishing a graphic model according to the product structure of the continuous winding equipment;

calculating the diaphragm pulling amount corresponding to the angles of the different turnover motors by using a mathematical model according to the graphic model;

transmitting the calculated matching data to an electronic cam table as stroke ratio data of the electronic cam;

The electronic cam adopts a mode of 'establishing a model', a two-dimensional model of equipment is established through a computer, and then the electronic cam is designed in a simulation mode, so that the accurate control of the active cache mechanism is realized.

As a further improvement of the above technical solution, the pattern model includes a spatial position of a discharge position of the active cache mechanism, a spatial position of the turntable, a spatial position of the wind-up roller, an outer diameter of the winding needle, and a rotation radius of the turntable. By simulating the data parameters, the calculated result can be more accurate.

In another aspect, an embodiment of the present invention further includes an active cache apparatus, including: at least one processor; at least one memory for storing at least one program;

when the at least one program is executed by the at least one processor, the at least one processor is enabled to implement the active caching method.

In another aspect, an embodiment of the present invention further includes a computer readable storage medium, on which a processor-executable program is stored, the processor-executable program being used to implement the active caching method when being executed by a processor.

In a final aspect, embodiments of the present invention also include a continuous winding machine comprising: the device comprises a controller, a diaphragm unwinding mechanism, a pole piece unwinding mechanism, a passive caching mechanism, an active caching mechanism and a winding mechanism, wherein a diaphragm material roll sequentially passes through the diaphragm unwinding mechanism, the passive caching mechanism, the active caching mechanism and the winding mechanism; the active cache mechanism comprises a driving motor, the turntable comprises a turnover motor, the driving motor and the turnover motor are both electrically connected with the controller, and the controller can realize the active cache method. Compare in current traditional electric core coiling equipment, this continuous winding machine has newly-increased an active buffer memory mechanism behind passive buffer memory mechanism, trades the station process at high speed, through active buffer memory mechanism with the storage of diaphragm initiative release, realizes trading the station process, and the most roller of diaphragm process need not produce the acceleration rate, reduces the violent range of unreeling the pendulum rod, reduces the diaphragm tension fluctuation of trading the station in-process, reduces the diaphragm dislocation and diaphragm and unreels that the buffer memory reaches extreme position and cause the alarm risk.

Meanwhile, all technical characteristics in the invention can be interactively combined on the premise of not conflicting with each other.

The embodiments of the present application will be further explained with reference to the drawings.

Referring to fig. 1, a brief description will be given of a continuous winding machine. The continuous winding machine includes: a controller (not shown), a membrane unwinding mechanism 100, a pole piece unwinding mechanism 200, a passive buffer mechanism 300, an active buffer mechanism 400, and a winding mechanism 500.

The number of the diaphragm unwinding mechanisms 100 and the number of the pole piece unwinding mechanisms 200 are two, and the two diaphragm unwinding mechanisms 100 and the two pole piece unwinding mechanisms 200 are arranged in a staggered mode. Namely, a pole piece unwinding mechanism 200 is arranged between the two diaphragm unwinding mechanisms 100, and a diaphragm unwinding mechanism 100 is also arranged between the two pole piece unwinding mechanisms 200. The membrane unwinding mechanism 100 is used for unwinding a battery cell membrane, the pole piece unwinding mechanism 200 is used for unwinding a battery cell pole piece, and the pole piece and the membrane can be processed into a square battery cell after passing through a continuous winding machine.

The forming quality of the battery cell is easily influenced by the fluctuation of the tension in the winding process due to the light weight of the diaphragm, so that after the diaphragm comes out of the diaphragm unwinding mechanism 100, a passive caching mechanism 300 is immediately connected, the passive caching mechanism 300 comprises a plurality of roller shafts 310, and some of the roller shafts are connected to a rack through springs, so that the relative positions of the roller shafts can be passively changed, for example, the roller shafts can be relatively displaced along with the changes of the unwinding tension, the winding state and the like of the diaphragm in the processing process, and the effect of adjusting the overall tension of the diaphragm is achieved; and simultaneously, the temporary storage diaphragm can also be used. Passive caching mechanism 300 is ubiquitous in the art and therefore will not be described in detail herein.

Compared with the prior art, the diaphragm directly enters the winding mechanism 500 after coming out of the passive buffer mechanism 300, the continuous winding machine innovatively adds the active buffer mechanism 400 between the passive buffer mechanism 300 and the winding mechanism 500, namely, the diaphragm enters the active buffer mechanism 400 firstly and then is sent to the winding mechanism 500 after coming out of the passive buffer mechanism 300.

Specifically, in this embodiment, the active buffer mechanism 400 includes a first driven roller 410, a second driven roller 420, a driving roller 430, and a driving motor (not shown in the figure), where the driving roller 430 is located between the first driven roller 410 and the second driven roller 420, the driving motor includes a linear push rod, the linear push rod is in driving connection with the driving roller 430, and the driving roller 430 may be connected to the frame through a linear sliding rail. The first driven roller 410, the second driven roller 420 and the driving roller 430 can relatively realize self-rotation motion. In use, the diaphragm exits the passive buffer mechanism 300, passes through the first driven roller 410, then the driving roller 430, then the second driven roller 420, and finally enters the winding mechanism 500. The positions of the first driven roller 410 and the second driven roller 420 relative to the frame are not changed, and when the relative position of the driving roller 430 is changed by the driving motor, the amount of the membrane stored in the active buffer mechanism 400 can be adjusted, for example, when the driving roller 430 is close to two driven rollers, the amount of the membrane stored is reduced, and when the driving roller 430 is relatively far away from the driven rollers, the amount of the membrane stored is increased.

The winding mechanism 500 comprises a turntable 510, the turntable is rotated by using a turnover motor, three groups of winding needles 520 are arranged on the turntable 510, the three groups of winding needles 520 are uniformly distributed on the turntable 510, namely, the phase angle between every two winding needles 520 is 120 degrees.

It is understood that in other embodiments, the number of winding pins 520 may be two or more than three.

When the winding machine works, the two groups of the membrane unwinding mechanisms 100 and the pole piece unwinding mechanisms 200 unwind simultaneously, and the membranes enter the winding needles 520 of the winding stations on the unwinding mechanism 500 after sequentially passing through the passive cache mechanism 300 and the active cache mechanism 400; after the pole pieces are discharged from the pole piece unwinding mechanism 200, the pole pieces also enter the same winding needle 520 after passing through a plurality of rollers, and then the winding needle rotates at a high speed to wind the two pole pieces and the two diaphragms together and process the pole pieces into a battery cell.

After the winding operation is completed in the winding needle 520 of the winding station, the turntable 510 starts to work, the turntable 510 drives the three winding needles 520 to change stations, the preliminarily formed battery cell can be transferred to the next station for subsequent processing, the empty winding needle is taken to the winding station, and the diaphragm and the pole piece are continuously received and wound. In this embodiment, the station that is located the carousel topmost is the station of coiling, and convolutes and accomplish the back, and the carousel can drive and roll up needle downstream (can be clockwise rotation, also can be anticlockwise rotation), carries out subsequent processing. When the rotary disc 510 rotates, the position of the winding needle also changes, and because the winding needle is also wound with a diaphragm, when the rotary disc 510 rotates, the diaphragm is additionally subjected to tension from the rotary disc 510, and particularly when the rotary disc 510 rotates at a high speed, the additional tension is very large, which may increase the over-roller acceleration inertia of the diaphragm, and simultaneously pull a tension swing rod of the passive cache mechanism to a large extent, even directly cause an alarm, seriously affect the stability of the device and cause the dislocation of the diaphragm.

In order to avoid the above situation, the continuous winding machine further includes an active buffer mechanism 400, during the winding process of the winding needle, the active buffer mechanism 400 is in a storage state, that is, the driving roller 430 is relatively far away from the two driven rollers, and more diaphragm materials are stored in the active buffer mechanism 400. When the turntable 510 starts to rotate, the driving motor also synchronously operates to drive the driving roller 430 to be relatively close to the two driven rollers, that is, the active cache mechanism 400 is in a discharge state, and the diaphragm in the active cache mechanism 400 is released; since the active buffer mechanism 400 additionally releases the diaphragm, when the rotary disc 510 changes the station of the driving winding needle 520, no additional tension is generated on the diaphragm, and the whole diaphragm is still in a stable state, so that accidents are reduced and the winding quality of electricity is improved. And the driving motor and the overturning motor are accurately controlled through the controller, and the speed matching of the driving motor and the overturning motor can be realized by utilizing the electronic cam, so that the diaphragm can not generate harmful tension fluctuation in the whole station changing process, and the smooth state is basically kept.

The active buffering method of the present application is further explained based on the continuous winding machine of fig. 1. The method comprises the following steps:

and S100, obtaining the electronic cam coupled with the driving motor and the overturning motor in a collection mode.

Referring to fig. 2, how to obtain the electronic cam is illustrated in a "self-learning" manner, and the method specifically includes, but is not limited to, the following steps:

s110, fixing the diaphragm at a feeding position of the active cache mechanism;

s120, switching a control mode of the driving motor to a reading mode;

s130, performing slow station changing action, and acquiring corresponding relation data of the position of the turnover motor and the position of the driving motor;

s140, after the station is changed, the data acquisition work is finished, and the acquired data is transmitted to the electronic cam meter to be used as stroke ratio data of the electronic cam;

and S150, generating the electronic cam according to the generated stroke ratio data by using the PLC electronic cam related command.

In step S110, the roller 310 of any one (preferably the last) of the passive buffer mechanisms 300 may be locked so that it cannot rotate, for example, the roller 310 is fixedly connected with a motor, and the roller 310 cannot rotate by locking the output shaft of the motor, but the friction between the surface of the roller 310 and the diaphragm is large, so that the diaphragm is difficult to move from the passive buffer mechanism 300 to the active buffer mechanism;

then, in step S120, the controller controls the operation mode of the driving motor, so that the push rod of the driving motor can be actuated when the driving motor receives an external force, and corresponding data can be recorded. It should be noted that although step S120 is after S110, the two steps do not have a strict sequence, and the sequence of the two steps may be interchanged.

Next, in step S130, the flipping motor starts to slowly operate to drive the rotating disc 510 to slowly rotate, where the rotating speed of the rotating disc 510 can be adjusted according to actual requirements, and the "slow speed" is relative to the "high speed" station change of the rotating disc 510 during the regular work. When the turntable 510 rotates slowly, the winding needle 520 is driven to move downwards, and the movement of the winding needle 520 causes the diaphragm to have a downward movement tendency, because the diaphragm is locked in the passive cache mechanism 300, the diaphragm can only be stretched from the active cache mechanism 400, that is, the roll material in the active cache mechanism 400 is passively released; therefore, as the winding needle 520 continuously moves downward, the driving roller 430 continuously approaches the two driven rollers, i.e., the push rod driving the driving motor is displaced. In the process, the position data of the turnover motor and the driving motor can be continuously collected. And the turnover motor can correspondingly obtain the data of the push rod of the driving motor at a certain position when driving the turntable to rotate by a certain angle, and the angle is in one-to-one correspondence with the position.

In step S140, after the winding needle 520 has moved downward to the designated station, the data collection operation is completed, and the collected data is transmitted to the electronic cam table as the stroke ratio data of the electronic cam, for example, the information of the reversing motor is the main shaft data, and the position information of the driving motor is the slave shaft data.

Finally, in step S150, the data obtained in step S140 is processed by the PLC controller using electronic software, and an electronic cam is generated by a relevant command.

With the electronic cam, the subsequent active cache release can be executed.

Referring to fig. 3, the electronic cam may be generated by "modeling" in addition to the above-mentioned "self-learning" method, and the specific method includes but is not limited to the following steps:

and S200, obtaining an electronic cam coupled by a driving motor and a turnover motor in a designed mode. The specific method comprises the following steps:

s210, establishing a graphic model according to a product structure of continuous winding equipment;

s220, calculating the diaphragm pulling amount corresponding to the angles of the different turnover motors by using a mathematical model according to the graphic model;

s230, transmitting the calculated matching data to an electronic cam table to serve as stroke ratio data of the electronic cam;

and S240, generating an electronic cam according to the generated stroke ratio data by using the PLC electronic cam related command.

Referring to fig. 4, in step S210, according to the product design of the continuous winding machine, the spatial position a1 of the discharge roller of the active buffer mechanism, the spatial position a2 of the turntable, the outer diameter A3 of the winding needle, the rotation radius a4 of the turntable, the position a5 of the winding needle of the first station, and the position a6 of the winding needle of the second station can be obtained;

then, in step S220, according to the data obtained in step S210, the pulling amount of the diaphragm between the discharge position of the active cache mechanism and the position of the winding needle can be calculated; the amount of pull is shown in the numerical sequence and is defined as X_nThen dividing the winding needle from the first position A5 to the second position A6 into n positions (n is a natural number), and calculating X when the winding needle is at different positions by means of a mathematical model_nA corresponding numerical value; wherein when n =0, i.e. the winding needle is located at the first position, X is defined₀=0。

Next, in step S230, the sequence X obtained in step 220 can be used_nAnd the position of the corresponding winding needle (the position is the rotating angle of the corresponding turntable), and the calculated matching data is transmitted to the electronic cam table to be used as the stroke ratio data of the electronic cam;

finally, in step S240, the data obtained in step S230 is processed by the PLC controller using electronic software, and an electronic cam is generated by a relevant command.

Referring to fig. 5, the active buffering method of the present application is further explained based on the continuous winding machine of fig. 1. The specific active caching method includes, but is not limited to, the following steps:

s10, executing the step S100 or the step S200 to obtain the required electronic cam;

s20, normally winding the winding needle of the continuous winding machine;

s30, judging whether each station on the winding mechanism is finished and the station is allowed to be changed, and executing the step S40 when the conclusion is positive;

s40, starting the turntable and starting to change stations; meanwhile, the active cache mechanism 400 acts, and the electronic cam obtained in the step S10 is used for controlling the driving motor to synchronously release the diaphragm;

s50, stopping the work of the turntable after the winding needle is in place;

s60, the active cache mechanism 400 starts to reset.

In step S60, in order to prevent the diaphragm from generating harmful tension fluctuation when the active buffer mechanism 400 is reset, the unwinding motor and the driving motor of the unwinding mechanism 100 may be synchronously controlled by using a principle similar to that in step S10.

Therefore, the continuous winding machine can effectively reduce the control of the tension fluctuation of the diaphragm when the station is changed. The quality of the battery cell in the continuous winding generation process is obviously improved.
