[0002] In the manufacturing process of lithium batteries, the positive and negative electrode materials are tightly combined with components such as diaphragms through heating and pressure. However, in the prior art, when hot pressing the lithium battery, the positive and negative electrode materials and the diaphragm need to be placed in a hot pressing mold, heated to a certain temperature by a hot press to soften and melt them, and at the same time, a certain pressure is applied by the hot press to tightly combine the negative electrode materials and components such as the diaphragm to form the internal structure of the battery. As a result, the lithium battery can only be hot pressed individually, and multiple lithium batteries cannot be hot pressed at the same time. For this reason, a multi-station battery hot pressing mechanism is proposed. Utility Model Content

[0009] Compared with the prior art, the beneficial effect of the utility model is that when the lithium batteries to be hot-pressed are transported to the second heat-conducting plates on both sides of the bottom end of the working frame through the cooperation between the material transport platform and the first drive guide rail, the pressure regulating hydraulic cylinder drives the pressing plate together with the first heat-conducting plate to move downward.
