Aluminum foil roll supporting mechanism for lithium battery and using method of aluminum foil roll supporting mechanism

Abstract

The invention discloses an aluminum foil roll supporting mechanism for a lithium battery, and belongs to the technical field of lithium batteries. The aluminum foil roll supporting mechanism comprisesa supporting base and a supporting frame installed on the upper surface of the supporting base. An air expansion shaft is arranged in the supporting base, rotating rods are movably installed at the two ends of the air expansion shaft through buckles, and a winding roll is installed on the outer surface of the air expansion shaft. A rotating rod on the front surface of the air expansion shaft is fixedly connected with an output shaft of a first motor. By arranging a supporting piece, extrusion rolls and a rubber scraper, when the thickness of aluminum foil on the surface of the winding roll isincreased, the two extrusion rolls are driven to be relatively away from each other, and then guide rods move leftwards and stretch a first spring under the hinge action of fixing plates, connectingrods and the guide rods. The extrusion rolls can make contact with the surface of the winding roll all the time through the elastic effect of the first spring, the surface of the aluminum foil can beextruded all the time, the occurrence of loosening phenomenon is avoided, the structure is simple, the surface of the aluminum foil can be scraped flat through the rubber scraper, and wrinkles are avoided.

Description

technical field [0001] The invention belongs to the technical field of lithium batteries, and in particular relates to an aluminum foil coil support mechanism for lithium batteries and a method for using the same. Background technique [0002] Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream. Lithium batteries can be roughly divided into two categories: lithium metal Batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. Lithium metal batteries, the fifth generation of rechargeable batteries, were born in 1996. Their safety, specific capacity, self-discharge rate and performance The price ratio is better than that of lithium-ion batteries. Due to its own high technical requirements, only a few companies in a few countries ar...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an aluminum foil roll support mechanism for lithium batteries and its use method. It uses a squeeze roller to cooperate with a support member and a rubber scraper, and uses a fan to cooperate with a filter screen and a cleaning brush to solve the above problems. The existing rewinding for aluminum foil production proposed in the background technology is simply to rewind and support the produced aluminum foil. Remove the impurity substances attached to the surface of the aluminum foil, so that the impurity substances adhere to the surface of the aluminum foil and cause the uneven surface of the aluminum foil to affect the normal use of the later period
