Abstract

The invention discloses tableting equipment and a tableting method. The tableting equipment comprises a base frame, wherein the base frame is provided with an upper diaphragm uncoiling mechanism, a lower diaphragm uncoiling mechanism, a pole piece uncoiling mechanism, a hot-pressing compounding mechanism and a slicing mechanism; the upper diaphragm uncoiling mechanism is used for providing an upper diaphragm; the lower diaphragm uncoiling mechanism is arranged below the upper diaphragm uncoiling mechanism, and is used for providing a lower diaphragm; the pole piece uncoiling mechanism is placed between the upper diaphragm uncoiling mechanism and the lower diaphragm uncoiling mechanism, and is used for providing a pole piece; the hot-pressing compounding mechanism is placed on the downstream side of the upper diaphragm uncoiling mechanism, the lower diaphragm uncoiling mechanism and the pole piece uncoiling mechanism; the hot-pressing compounding mechanism comprises an upper hot-pressing roller, and a lower hot-pressing roller which is placed below the upper hot-pressing roller and is in tight fit with the upper hot-pressing roller; the slicing mechanism is arranged on the downstream side of the hot-pressing compounding mechanism. By adopting the tableting equipment and the tableting method, the tableting quality and tableting efficiency can be improved and increased, and meanwhile the tableting cost is lowered.

Description

technical field [0001] 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. Background technique [0002] 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 r...
