The unwinding mechanism 8 is used for unwinding the coil 3; the engraving device 9 is used to perform engraving and code scanning operations on the web 3 and may preferably be a laser engraving device.
Based on the same design idea, the invention also provides an embodiment of a processing technology of the lithium battery adhesive tape, and the processing technology comprises the following steps:
s1, controlling an unreeling mechanism 8 to carry out unreeling operation, and enabling the unreeled coil stock 3 to continuously move;
s2, controlling the engraving and printing equipment 9 to perform continuous engraving and printing operation on the continuously moving coil stock 3;
s3, the coil 3 subjected to the marking operation passes through a space between the compression roller 1 and the winding shaft 2, the winding shaft 2 compresses the coil 3 on the compression roller 1, and the compression roller 1 actively rotates to drive the coil 3 to continuously move, so that the air bubble pressing operation is performed on the coil 3;
s4, the compression roller 1 actively rotates and drives the winding shaft 2 to synchronously rotate, so that the coil 3 is wound on the winding shaft 2, and the winding operation of the coil 3 is completed.
In the technical scheme of the embodiment, the method comprises 4 working procedures, namely unwinding operation → marking operation → air bubble compressing operation → winding operation.
In the unreeling operation of the step S1 and the engraving operation of the step S2, the unreeled roll 3 is in a continuously moving state, and the engraving device 9 performs the continuous engraving operation on the continuously moving roll 3, so that the unreeling efficiency and the engraving efficiency of the roll 3 are high, the technical problem that the roll 3 in the prior art needs to stop to be used for the engraving device 9 to complete the engraving code scanning operation and then continuously move after moving for a preset or specified length is solved, the time of the unreeling and engraving operations is remarkably reduced, and the overall processing efficiency of the roll 3 is remarkably improved.
In the bubble pressing operation of step S3, because set up a compression roller 1 and can correspond multiunit rolling axle 2 and coil stock 3 to accomplish simultaneously bubble pressing and rolling operation to coil stock 3, so when switching the coil stock 3 of different width specifications or processing the coil stock 3 of different width specifications simultaneously, need not to change the compression roller 1 of corresponding specification, only need adjust the pressure between compression roller 1 and the coil stock 3 can, easy and simple to handle, production efficiency is high and can show reduction in production cost. And, because compression roller 1 initiative is rotated in order to drive coil stock 3 and is continuously removed, when the event carries out the rolling to a plurality of coil stocks 3 of same specification, only need guarantee that rolling shaft 2 can to the uniformity of coil stock 3 pressure size, when carrying out the rolling to a plurality of coil stocks 3 of different specifications, only need according to coil stock 3 width specification adjustment rolling shaft 2 to coil stock 3 pressure size can to improve the variety of this lithium electricity sticky tape processing equipment to 3 processing of multiple different specifications coil stocks.
In the winding operation of step S4, the pressure roller 1 actively rotates to drive the winding material 3 to continuously move, the winding material 3 drives the winding shaft 2 to synchronously and reversely rotate relative to the pressure roller 1, that is, the winding shaft 2 obtains the torque required for winding the winding material 3 through the friction between the winding shaft and the winding material 3, and the winding shaft 2 continuously winds the winding material 3 in the continuous moving process of the winding material 3, thereby completing the winding operation.
According to an alternative embodiment of the present invention, in the step S1, the unwinding operation includes a single roll unwinding operation and/or a long mother roll unwinding operation. Particularly, no matter what unreeling mode, the structural design mode that the plurality of reeling shafts 2 are arranged corresponding to the press roller 1 can realize unreeling, imprinting, bubble pressing and reeling operations of a single-reel coil 3, a plurality of reels of the same specification 3 and a plurality of reels of different specifications 3.
According to another alternative embodiment of the present invention, in step S2, the film surface of web 3 includes a plurality of imprinting areas, and after completing the imprinting operation of one set of imprinting areas, imprinting apparatus 9 automatically captures the next set of imprinting areas to be imprinted for the imprinting operation. In the prior art, a processing mode of "the web 3 moves for a preset length → the web 3 is still for the engraving device 9 to engrave the relevant content on the film surface → the web 3 moves again to let the next group of films to be engraved enter the engraving area" is generally adopted, and the unwinding efficiency and the engraving efficiency of the web 3 are low. In the technical solution of this optional embodiment, the web 3 unwound by the unwinding mechanism 8 is in a continuous moving state, the imprint apparatus 9 performs a continuous imprint operation on the web 3 that continuously moves, and after the imprint apparatus 9 performs imprinting on the content of the group, the laser automatically captures the next group of imprint regions that need to be imprinted to perform the imprint operation. The unreeling and the marking operations do not need to be stopped, so that the unreeling and the marking operations are obviously shortened, and the overall processing efficiency of the coil stock 3 is obviously improved.
In another embodiment of the present invention, in step S3, the pressure of the winding shaft 2 on the web 3 is adjusted by the rocker mechanism, so as to adjust the bubble force of the pressure roller 1 on the web 3. Wherein, because coil stock 3 sets up between rolling axle 2 and compression roller 1, and rolling axle 2 compresses tightly coil stock 3 on compression roller 1 to the relativity of power says that rolling axle 2 has the pressing force towards compression roller 1 axial direction to coil stock 3, then compression roller 1 also produces the pressing force towards the axis direction of rolling axle 2 to coil stock 3, and this pressing force is the bubble effort of pressing of compression roller 1 to coil stock 3 promptly. More specifically, the pressure bubble force of the compression roller 1 on the coil 3 can be adjusted, so that the diversified requirements of various specifications on the pressure bubbles and the winding process of the coil 3 or the coils 3 of the same specification can be met.
According to one preferable scheme of the embodiment, in the step S3, the pressure of the winding shaft 2 at the end of the second rocker arm 5 on the web 3 is adjusted by controlling the second rocker arm 5 to rotate relative to the first rocker arm 4. Particularly, because the winding shaft 2 is arranged at the end part of the second rocker arm 5, when the second rocker arm 5 is controlled to rotate or swing relative to the first rocker arm 4, the relative position of the winding shaft 2 relative to the coil 3 can be adjusted or the pressure of the winding shaft 2 to the coil 3 can be adjusted, and then the diversified requirements of multiple specifications on the bubble pressing and winding processes of the coils 3 or the coils 3 with the same specification can be met.
According to another preferable scheme of the embodiment, in the step S3, the output end 7 of the driving mechanism 6 is controlled to perform reciprocating linear motion, so as to drive the second rocker arm 5 to rotate relative to the first rocker arm 4. Specifically, since the output end 7 of the driving mechanism 6 is rotatably connected to the second swing arm 5, the second swing arm 5 can be driven to rotate or swing about the connection point between the first swing arm 4 and the second swing arm 5 while the output end 7 linearly reciprocates. Further, when the second rocker arm 5 rotates or swings, the relative position of the winding shaft 2 relative to the compression roller 1 or the pressure of the winding shaft 2 to the compression roller 1 can be adjusted, that is, the pressure bubble force of the compression roller 1 to the coil 3 can be adjusted.

Particularly, at the rolling in-process of coil stock 3, coil stock 3 continuously twines on rolling shaft 2, so thickness on the rolling shaft 2 constantly increases, if adjust rolling shaft 2 to the pressure size of coil stock 3 in time this moment, then compression roller 1 will be not corresponding with the coil stock 3 of this kind of width specification to the bubble dynamics of calming the anger of coil stock 3 to influence the bubble calming the anger effect. Therefore, the pressure of the winding shaft 2 to the coil 3 is adjusted in real time according to the winding thickness of the coil 3 on the winding shaft 2, and the pressure bubble force of the compression roller 1 to the coil 3 is adjusted in real time, so that the pressure bubble force of the compression roller 1 is adaptive to the width specification of the coil 3 in the winding and pressure bubble pressing process, and the influence of the thickness of the coil 3 wound on the winding shaft 2 is avoided.
Furthermore, in the invention, by using a moment balance equation, the real-time angle and weight are calculated by a program after the stress is simplified, and then the real-time air pressure input value of the air cylinder can be obtained, which is concretely as follows:
the overall force of the rocker arm mechanism is simplified as shown in fig. 3 (which is an instant schematic diagram, and the included angle of the force changes in real time along with the change of the number of meters of the coil stock 3), and is respectively the self weight of the rocker arm mechanism, the acting force of the cylinder, the gravity of the coil stock and the acting force of the pinch roller acting on the rocker arm mechanism, and the following equation is obtained by taking the rotation center of the rocker arm mechanism as the moment center through a moment balance equation: f a ×L a +F d ×L d ＝F b ×L b +F c ×L c . Therefore, as the number of meters for winding increases, the real-time angle is calculated through the thickness of the coil stock 3 and the number of meters, the air pressure required to be input in real time can be calculated according to the equation, and the required rocker arm air pressure can be obtained through the PLC control proportional valve, so that constant-pressure winding is realized (in the winding process, the gravity of the rocker arm mechanism is unchanged, and as the number of meters increases and the gravity of the coil stock increases, the pressure theory needs to be ensured to be almost unchanged, namely, the pressure theory needs to be ensured to be almost unchanged in real time, namely, the real-time angle is calculatedAdjusting cylinder force). Through the control mode, the pressure can be controlled in real time, the adjustment process is greatly simplified, and the highly intelligent control of the coil splitting is realized.
Wherein F a Acting force for cylinder, L a A force arm corresponding to the acting force; f b Is the weight of the rocker arm mechanism, L b A force arm corresponding to the acting force; f c For the gravity of the coil stock, L c A force arm corresponding to the acting force; f d Acting force of rocker arm mechanism for pinch roller, L d A force arm corresponding to the acting force; the rolling diameter range of the single rocker arm is 90-350mm (diameter), and the air pressure range of the rocker arm is-0.6-0.6 MPa.
According to another preferable scheme of the embodiment, in the step S3 and the step S4, a first friction force and a second friction force exist between the web 3 and the pressing roller 1 and between the web 3 and the winding shaft 2, the pressing roller 1 drives the web 3 to move continuously by the first friction force, and the continuously moving web 3 drives the winding shaft 2 to rotate by the second friction force. Specifically, the web 3 obtains a moment of continuous movement by a first frictional force between the web 3 and the press roll 3, thereby completing the puffer operation during the continuous movement of the web 3. The winding shaft 2 obtains a moment of continuous rotation, namely a winding moment, through a second friction force between the winding shaft 2 and the coil 3, so that the coil 3 is continuously wound on the winding shaft 2, and the winding operation is completed.
