Operation principle of the present utility model and the course of work are：

When carrying out the making of lithium ion laminated battery using the utility model device, is sequentially arranged along runner direction of rotation One membrane coil, negative pole volume, the second membrane coil, positive pole volume.Two barrier film raw bands sequentially pass through membrane tension wheel, barrier film transition respectively Wheel, diaphragm deviation rectifying sensor, diaphragm deviation rectifying driven roller, the first diaphragm deviation rectifying driven roller drive the charging of the first barrier film raw band, lead to Cross the first diaphragm deviation rectifying sensor test position deviation and feed back to the first diaphragm deviation rectifying driven roller, the first diaphragm deviation rectifying driven roller The feed entrance point of the first barrier film raw band will be adjusted, when the first barrier film raw band reaches the periphery of runner, now pinch roller will The first barrier film raw band is set to be close to runner periphery and be moved with runner.

Negative pole raw band sequentially passes through negative pole straining pulley, negative pole transition wheel, negative pole deflection correction sensor, negative pole correction driving Roller, negative pole cutter, negative pole correction driven roller drive the charging of negative pole raw band, by negative pole deflection correction sensor test position deviation And negative pole correction driven roller is fed back to, negative pole correction driven roller will adjust the feed entrance point of negative pole raw band, when negative pole raw band When reaching the periphery of runner, now pinch roller will be such that negative pole raw band is close on the first barrier film raw band of lower section and with runner Motion, after negative pole raw band discharges a segment distance, negative pole cutter begins to switch off negative pole raw band, can now be obtained on runner To negative plate.

For the second membrane coil between both positive and negative polarity volume, the motion process of its second barrier film raw band and above-mentioned first The motion process of barrier film raw band is similar to, and when the second barrier film raw band reaches the periphery of runner, now pinch roller will make second Barrier film raw band is close on the negative plate of lower section and is moved with runner.

Positive pole raw band sequentially passes through positive pole straining pulley, positive pole transition wheel, positive pole deflection correction sensor, positive pole correction driving Roller, positive pole cutter, positive pole correction driven roller drive the charging of positive pole raw band, by positive pole deflection correction sensor test position deviation And positive pole correction driven roller is fed back to, positive pole correction driven roller will adjust the feed entrance point of positive pole raw band, when positive pole raw band When reaching the periphery of runner, now pinch roller will be such that positive pole raw band is close on the second barrier film raw band of lower section and with runner Motion, after positive pole raw band discharges a segment distance, positive pole cutter begins to switch off positive pole raw band, can now be obtained on runner To positive plate.

Now, the first barrier film-negative plate-the second barrier film-positive plate completes lamination action, is entangled by adjusting positive and negative electrode The charging rate of inclined driven roller can realize the center alignment of positive and negative plate.The direction of rotation of runner and heat pressure roller is opposite and two Person reaches certain hot pressing temperature by the heating of internal resistance silk, and driven by rotating wheel pinch roller is done in itself along runner periphery The rotary motion of heart axis.Two-layer barrier film now is still material strip form, and pinch roller makes above-mentioned four component be close to runner periphery And runner bottom is moved with it, and first pass through runner and preheated, it is compound then to carry out pole piece heat by heat pressure roller.Heat is compound After the completion of, positive and negative plate is bonded together with two barrier film raw bands, forms unit material strip.

Unit material strip sequentially passes through unit feeding straining pulley, unit feeding transition wheel, unit feeding deflection correction sensor, unit Feeding correction driven roller, unit cutter, unit feeding correction driven roller band moving cell material strip charging, are fed by unit and rectified a deviation Sensor test position deviation simultaneously feeds back to unit feeding correction driven roller, and unit feeds correction driven roller by adjustment unit material strip Feed entrance point.

When unit material strip moves to unit nip rolls position, two unit nip rolls now are driven by two pinch roller motors respectively After dynamic and direction of rotation is conversely, unit material strip clamps and moved a segment distance by unit nip rolls, unit cutter begins to switch off two Layer barrier film, now unit nip rolls clamping is single four layer unit.

Unit nip rolls clamps single four layer unit to be continued to move, and now cylinder drives holding frame near stack of cells stacked box It is located proximate to, when initially stacking, the bottom of right sided cell pressure roller is in close contact with the upper surface of stacking plate, with the shifting of holding frame Dynamic, single four layer unit is pressed on left cell pressure roller the upper surface of stacking plate, completes a placement for four layer units.

Then cylinder drives the quick position to away from stack of cells stacked box of holding frame to move again, and four layer units begin during this It is pressed on stacking plate by unit pressure roller eventually, when unit nip rolls moves to unit cutter lower section, now unit material strip is again Clamped by unit nip rolls, after unit nip rolls grip unit material strip moves it a segment distance, unit cutter begins to switch off two-layer Barrier film, now unit nip rolls clamping is single four layer unit.

Unit nip rolls clamps single four layer unit to be continued to move, and now cylinder drives holding frame near stack of cells stacked box It is located proximate to, four layer units are pressed on the above-mentioned upper surface for having stacked four layer units by left cell pressure roller, now completes two The stacking of four layer units.

Circulation is carried out successively, until four layer units are stacked into the specified number of plies, stacking plate is with four layer unit stacking numbers Increase and gradually move down.Because battery battery core is made up of some four layer units and a three-layer unit, this three-layer unit be every Film-negative plate-membrane configuration, the three-layer unit makes still through above-mentioned pole piece Qie Die mechanisms, only needs positive pole to roll up and stops supplying Material is i.e. available.

After completing the making of battery battery core, unit nip rolls revert to the lower section of unit cutter, and now cylinder is not reoperated, Being taken out by the battery core that the gap Jiang Dui between blowpit, unit pressure roller is folded using artificial or manipulator carries out encapsulated work Industry, so far single battery core completion makes.

While taking out battery core, unit nip rolls still continues rotation, and unit material strip is clamped by unit nip rolls again, unit folder After roller grip unit material strip moves it a segment distance, unit cutter begins to switch off two-layer barrier film, now the clamping of unit nip rolls Be single four layer unit.Four layer units now enter unit connecting gear, and transmission wheel drives conveyer belt, both sides transmission The unit clamping device of lower section is moved to four layer units of clamping, and the system of battery battery core is completed in corresponding stack of cells stacked box Make.

Said process is repeated, recycling for multiple stacking stations is realized.

From above technical scheme, the utility model can easily realize the section of four layer units, lamination, hot pressing, Barrier film operation is cut, four layer unit stack manners are simple, efficient, can be stacked when compressing, and stacking positioning precision is high.Multiple pileup work Recycling for position, will not produce the stacking stand-by period, substantially increase production efficiency.Even if the utility model device is long-term Still there is good performance after use, the core competitiveness of battery manufacture enterprise can be effectively improved.
