The hot pressing method and device for loading and unloading of battery cells in a hot press machine, wherein the hot pressing method for loading and unloading of battery cells in a hot press machine includes: loading the battery cells, horizontally conveying the battery cells that need to be hot pressed to a preset position through a conveyor belt; Cell hot pressing, using a hot pressing plate to hot press the cells that have reached the preset position. The hot pressing plate does not directly contact the cells during the hot pressing process; Cell cutting, the cells that have completed the hot pressing process are cut, and the cells are transported away from the hot pressing position by a conveyor belt to complete the cutting;

The loading and unloading hot pressing device of the battery cell hot press machine includes a hot pressing plate and a conveyor belt; The hot press plate includes a lower hot press plate and an upper hot press plate. The upper and lower hot press plates are used to apply pressure to the battery cell, and the upper and lower hot press plates are in indirect contact with the battery cell.

The hot pressing method and device for loading and unloading of battery cells in a hot press machine have advantages that existing technologies do not possess, such as simple structure, convenient implementation, low implementation cost, good quality of battery cell hot pressing, and high safety performance of battery cells.

Features of battery cell hot press machine:

1. Host control system program control; Set the parameters required for multi-step pressurization routine; The main pressure reading is in MPa, with two decimal places retained; The temperature display shows+0.1 ℃;

The database has data storage, output, and printing capabilities; Preservation and retrieval of historical data; Store the curve graphs generated by temperature, pressure, time, etc. during the operation process; And it can store multiple sets of data for visual comparison of different operational changes in production; Clearly list the operation data and load additional information functions such as operation time, personnel, number, and test series materials; When printing, the required content can be retrieved through the main keyword for printing and document preparation

The pressurization speed of the operating system can be changed as needed during the pressurization process; During the travel process, fast and slow pressurization can be achieved, and the transition between fast and slow speeds is controlled by the program's sequential operation settings; The pressure buffer is within 5%

The automatic pressure holding system is set to a duration of 30 minutes; Good pressure stability during the holding process

5. Fast response speed. Concentrated heat, especially suitable for welding workpieces with small spacing and fast thermal conductivity
