Problems solved by technology
The existing production line needs to be shut down when the base film unwinding roller is changed, the base film stops pulling, and the old roll and the new roll are connected before starting up, which takes a certain amount of time
However, part of the coated film on the production line is in the process of heat treatment or stretching, and stopping the traction will easily cause the entire diaphragm to become a defective product

The invention belongs to the technical field of lithium battery diaphragm production, and in particular relates to a coil changing machine, a coil changing method and a production line for lithium battery diaphragm production. The roll changing machine for lithium battery diaphragm production includes: a control module; a roll unwinding rack for placing new rolls and old rolls; Paste the new roll film on the old roll film pasted with adhesive tape; the adhesive strip detection module is used to detect the adhesive tape pasted on the old roll film; and the old roll film cutting mechanism; wherein the control module is suitable for receiving After the signal sent by the glue strip detection module, the film splicing mechanism is controlled to paste the new roll film on the old roll film with the glue strip attached, and then the old roll film cutting mechanism is controlled to cut off the old roll film.
Description
technical field [0001] The invention belongs to the technical field of lithium battery diaphragm production, and in particular relates to a coil changing machine, a coil changing method and a production line for lithium battery diaphragm production. Background technique [0002] Lithium battery diaphragm production technology - dry and wet. The production process of lithium battery separator is complicated. The many characteristics of lithium battery separator and the difficulty of taking into account its performance indicators determine the high technical barriers to its production process and the difficulty of research and development. According to the difference in the mechanism of micropore formation, the diaphragm process can be divided into two types: dry method and wet method. [0003] Dry method - first melt, extrude and blow polyolefin resin to form a crystalline polymer film, then conduct crystallization heat treatment and annealing operations to obtain a highly o...
