Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery pole piece compounding, in particular to a battery pole piece preheating compounding mechanism. BACKGROUND

[0002] In the production process of lithium batteries, the manufacturing of bare cells is mainly through two technologies: winding and stacking. The winding process has been the mainstream of lithium battery manufacturing for a long time due to its high maturity, low cost, high production efficiency and high yield. However, with the development of 3C electronic products towards intelligence, thinness and portability, and the rapid growth of the new energy vehicle industry, the market has put forward higher requirements for the safety, energy density and service life of batteries. The winding battery has increasingly highlighted problems such as low space utilization, poor structural stability and short cycle life caused by its structural characteristics. In contrast, the stacking process is gradually becoming a new trend in the development of lithium battery structure due to its advantages of providing higher energy density, longer cycle life and better structural stability. This process arranges electrodes and separators more closely, not only improves the energy density of the battery, but also helps the battery maintain a more uniform temperature distribution during charging and discharging, reducing the formation of hot spots, thereby improving the performance and safety of the battery. In addition, the stacking process is generally considered to be simpler and more direct than the winding process, reducing the risk of mechanical failure and maintenance costs. For the manufacturing of large-size batteries, such as those used in electric vehicles or energy storage systems, the stacking process can more easily expand to the production of large-area electrodes, while the winding process may encounter problems in winding uniformity and tension control when handling these electrodes.

[0003] Although the stacking process has many advantages, it still has some defects in practical application. The widely used Z-type stacking technology, although it can significantly improve the performance of the battery, has a slow stacking speed, and in the process of the robot placing the cut positive and negative pole pieces alternately on the separator to form a "Z" type staggered stack, the risk of pole piece misalignment and separator stretching deformation is high, and the production efficiency and yield are low.

[0018] (Three) beneficial effects

[0019] The application adopts a new type of laminated sheet mode of composite laminated sheet, that is, the diaphragm and the positive / negative sheet are first combined by pressure roller heating to form a composite unit composed of diaphragm-sheet-diaphragm or diaphragm-sheet-diaphragm-sheet, and then a plurality of composite units are stacked into a battery cell by various ways. During operation, the strip of sheet and diaphragm enters from the feeding side at the same time, and is first preheated by the preheating mechanism to soften or melt the adhesive on the sheet. The preheating mechanism is beneficial to the adhesion between the sheet and the diaphragm, and can dry the sheet and diaphragm, thereby reducing the probability of air bubbles generated during thermal compounding. The preheated strip passes through the upper and lower composite rollers of the first composite mechanism, and is tightly bonded after heating; the upper composite roller is driven downward by the air cylinder to press the strip between the two rollers, and the two rollers are driven to rotate by the servo motor, thereby pressing and pulling out the sheet and diaphragm. The composite preheating mechanism between the first thermal compounding mechanism and the preheating mechanism continuously heats the strip between the two mechanisms to prevent the strip from cooling when waiting for compounding, thereby affecting the adhesion effect. The air knife and brush roller on the side of the pressure roller can remove dust particles or dirt on the surface of the composite roller to prevent dust and impurities from being pressed into the sheet to cause short circuit of the battery cell and improve the performance of the battery cell. Finally, the composite sheet is pulled out from the first composite mechanism to the second composite mechanism for secondary compounding to solve the problems of poor adhesion, uneven thickness, etc. during the first compounding, and remove the air bubbles remaining during the first compounding to help the adhesive flow better to fill the gap and improve the compounding effect. In addition, a lifting roller is arranged behind the composite mechanism to prevent the strip from accumulating or being pulled due to the inconsistent pulling speed between the two mechanisms, maintain the tension of the strip, avoid stress concentration points, wrinkles and misalignment, and maintain the integrity of the strip structure. The composite effect of the application is good, the production efficiency is high, the yield is high, the sheet misalignment does not occur, and the quality of the battery cell produced is good.
