[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The formation equipment was originally split-type, that is, the mechanical cabinet part and the power cabinet part were separated and located in two different factories. The operation of the equipment depends on the cooperation of the mechanical cabinet part and the power cabinet part. Therefore, the two need to be connected by cables through the wall. The blade battery constant temperature all-in-one machine is an integrated type, that is, the mechanical cabinet part and the power cabinet part are assembled into one device. There is no need for a large number of cables to connect the two, saving cables and reducing costs. At the same time, compared with the split type, the integrated type has all the equipment located in the same factory building, eliminating the construction of the power cabinet part of the factory building, and effectively improving the site utilization rate.

[0020] 2. After the formation equipment is manufactured, various debugging is required to verify the availability of the equipment and meet the various needs of customers. After debugging, it is transported to the site for installation. The mechanical cabinet part and the power cabinet part of the split equipment are installed in different workshops. After the installation of both, debugging is required again to ensure the reliability and stability of the equipment. After the installation of the integrated equipment is completed, no further debugging is required before power is turned on. The equipment can be fine-tuned and improved according to the site requirements later, saving on-site debugging time and facilitating on-site installation.

[0021] 3. The chemical process has strict control over temperature. The mechanical cabinet part of the split-type equipment has strict requirements on the temperature of the factory, and it is necessary to ensure a constant high temperature in the factory. The integrated equipment has no strict requirements on the factory, and normal temperature is sufficient. Only the mechanical cabinet part inside the equipment needs to maintain a constant high temperature state, which saves energy loss and makes it easier for workers to enter the factory to operate.

[0022] 4. The original formation equipment was an integrated type, that is, all the presses in the warehouse shared a heating system. However, the blade battery constant temperature integrated machine has independent heating systems for the first chamber and the second chamber. When the battery cells in the first chamber have completed the corresponding heating and formation, the battery cells that have completed the heating and formation in the first chamber can be taken out directly without waiting. At this time, because the first chamber and the second chamber are not only physically isolated in space, but also the corresponding heating systems are relatively isolated, they will not affect each other. The corresponding battery cell processing process will be more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
