Description
技术领域technical field
本申请涉及锂电池生产设备领域，具体涉及一种锂离子动力电池生产中的制片设备及制片方法。The present application relates to the field of lithium battery production equipment, in particular to a sheet-making equipment and a sheet-making method in the production of lithium-ion power batteries.
背景技术Background technique
现有的制袋式制片采用类似冲床(压力机)的间歇式制袋机构，而且不进行热复合。这种机构不能实现连续制袋，使得放卷机构不能平稳运转，因此在放卷后要增加张紧缓存部件来适应间歇制袋机构。张紧缓存部件的增加，不仅增加了成本，而且加长了带路的长度，增加了带路跑偏的可能性。为了防止带路跑偏，又要增加行进纠偏部件，这就更增加了带路的长度。带路长度的增加，又产生了新的问题，就是换卷接带的问题。只好再增加接带装置。这就使得设备过于复杂，成本很高，操作和控制比较麻烦。The existing bag-making type tablet adopts an intermittent bag-making mechanism similar to a punch (press), and does not carry out thermal compounding. This mechanism cannot realize continuous bag making, so that the unwinding mechanism cannot run smoothly. Therefore, after unwinding, tension buffer parts must be added to adapt to the intermittent bag making mechanism. The increase of tensioning and buffering components not only increases the cost, but also lengthens the length of the belt, increasing the possibility of the belt running off course. In order to prevent the deviation of the leading road, it is necessary to increase the traveling deviation correcting parts, which further increases the length of the leading road. The increase of the length of the belt path has produced a new problem, which is exactly the problem of changing the roll and connecting the belt. Had to increase the connecting device again. This just makes the equipment too complicated, the cost is very high, and the operation and control are cumbersome.
现有的制袋式制片方法更换产品是需要更换模具，而新的方法无需更换模具，热压模块不需要改变即可更换产品。Existing bag-making tablet-making method needs to change the mold to change the product, but the new method does not need to change the mold, and the hot pressing module can change the product without changing.
现有的制袋制式制片隔膜的宽度要比极片的宽度大出1到2毫米，这就使得每个极片要浪费4到8毫米。The width of the existing bag-making system film-making diaphragm is 1 to 2 millimeters larger than the width of the pole piece, which makes each pole piece waste 4 to 8 millimeters.
