A battery separator is reversed to the smoothing roller after being coated out of the drying oven

Abstract

The invention discloses a reverse direction troweling roller after the battery diaphragm is coated out of a drying box, including a drying box, a coating mechanism arranged on the front side of the drying box, and a reverse wiper installed on the lower rear side of the drying box. Leveling mechanism, and a winding mechanism arranged on the rear side of the reverse troweling mechanism; a conveyor belt is installed in the drying box; a film is placed on the conveyor belt; the reverse troweling mechanism is sequentially arranged from front to back Including stainless steel roller guide roller, first stainless steel guide roller group, ceramic smoothing roller, second stainless steel guide roller group and rubber pressure roller. After the battery diaphragm of the present invention is coated out of the drying box, it is reversed to the smoothing roller, and the ceramic smoothing roller is driven by a motor to rotate, and the direction of rotation is set to be opposite to the direction of motion of the film. The coating is smoothed without damaging the film, and it can ensure the uniformity of the film coating.

Description

technical field [0001] The invention relates to a reverse direction smoothing roller, in particular to a reverse direction smoothing roller after the battery diaphragm is coated out of a drying box. Background technique [0002] Cylindrical lithium-ion batteries are divided into different systems of lithium iron phosphate, lithium cobalt oxide, lithium manganese oxide, cobalt-manganese mixture, and ternary materials. The shell is divided into two types: steel shell and polymer. Batteries with different material systems have different advantages; The technology is mainly based on steel shell cylindrical lithium iron phosphate batteries. The iron lithium batteries are characterized by high capacity, high output voltage, good charge and discharge cycle performance, stable output voltage, high current discharge, electrochemical stability, and safety in use. , will not cause combustion or explosion due to improper operations such as overcharging, overdischarging, and short circui...

[0002] Cylindrical lithium-ion batteries are divided into different systems of lithium iron phosphate, lithium cobaltate, lithium manganate, cobalt-manganese mixed, and ternary materials. The shell is divided into two types: steel shell and polymer. Batteries with different material systems have different advantages; existing The technology is mainly based on steel shell cylindrical lithium iron phosphate battery. The performance of iron lithium battery is high capacity, high output voltage, good charge and discharge cycle performance, stable output voltage, high current discharge, electrochemical stability, and safety in use. , will not cause combustion or explosion due to improper operation such as overcharging, overdischarging, and short circuit, and has a wide operating temperature range and is environmentally friendly; it is widely used in solar lamps, lawn lamps, backup energy, power tools, and toy models; for cylinders type lithium battery, the quality of the positive and negative electrodes directly affects the quality of the battery; the existing production process of the positive and negative electrodes is as follows: first, the electrodes are coated, and then enter the oven after being coated by a coating roller, and the coated film is coated The layer is not uniform and smooth, but uneven, and it is necessary to roll the film coating. However, in the prior art, when the film coating is rolled, it is easy to cause incomplete rolling, or even due to excessive rolling. damage the film surface
