The invention discloses a device for manufacturing a laminated battery unit, which comprises a diaphragm cutting and transferring device, a pole piece transferring device and a conveying belt; there are two pole piece transferring devices, which are positive and negative pole piece transferring devices respectively; The platform is placed next to the positive and negative electrode sheet transfer devices, which are used to transfer the separator to the positive and negative electrode sheet stack after cutting; the positive and negative electrode sheet transfer devices are used to transfer the positive and negative electrode sheets to the positive and negative electrode sheet stacks respectively. The positive and negative electrode diaphragm units are formed with the separator, and then the positive and negative electrode diaphragm units are transferred to the conveyor belt to form a laminated battery unit. The device provided by the invention can compound the pole pieces into several layers of small battery units, and then make these small units into batteries, which can separate the positive and negative pole piece stacking processes, save half of the stacking time, and greatly improve the battery life. The production efficiency is improved; moreover, the device can be integrated into one production line, which is especially suitable for the mass production of laminated batteries.
Description
technical field [0001] The invention relates to a battery manufacturing device, in particular to a laminated battery unit manufacturing device. Background technique [0002] The common production method of lithium-ion batteries is the winding production method. This method has the advantages of high production efficiency, low cost, and simple operation, but it also has large internal resistance, general cycle performance, and poor high-rate charge-discharge performance. shortcoming. These disadvantages have greatly limited the use of wound lithium-ion batteries as a power source. Batteries made by laminated sheets have the advantages of small internal resistance, good cycle performance, and high-rate charge and discharge, and are suitable as power sources. Therefore, they have received more and more attention, and the market share of laminated batteries has gradually increased. However, the manufacturing process of laminated batteries is complicated, the efficiency is low,...
