Description

Technical Field

[0001] The invention relates to the technical field of composite current collector coating, and in particular to a composite current collector coating adaptive spacing adjustment device. Background Art

[0002] The current collector refers to the lithium battery component used to collect lithium ions, electrons or charges at the positive and negative electrodes of the lithium battery. In order to improve the safety and energy density of the battery, a composite current collector has been introduced. The copper foil and aluminum foil in the traditional current collector have been replaced with composite copper foil and composite aluminum foil. When the composite copper foil is plated on both sides of the film, magnetron sputtering copper plating is generally used.

[0003] After coating, the film needs to be reeled up. However, the film may break due to equipment failure or excessive film tension. After the film breaks, the film on the reel will not be subjected to tension, so the film on the reel will become loose. To solve the above problem, a push roller will be installed on one side of the reel. When the film breaks, the push roller will move toward the direction of the reel and then push the film against the reel to prevent the film from loosening.

[0004] However, after the push roller supports the film, the film on the winding roller needs to be removed. At this time, the film on the winding roller is in contact. When the film roll is pulled out, the film will rub against the push roller, which may cause wrinkles in the film, thereby affecting the production quality of the film. Summary of the invention
