Dispensing device for lithium-ion battery (LIB) separator

A dispensing device for a lithium-ion battery (LIB) separator, comprising a coating adhesive transferring device, wherein the coating adhesive transferring device comprises an adhesive accommodating device and a relief roll;

• accommodating grooves for accommodating adhesives are provided on the adhesive accommodating device;
• transferring protrusions are arranged on a rolling surface of the relief roll;
• the transferring protrusions are configured to insert into corresponding ones of the accommodating grooves on the adhesive accommodating device to transfer a separator coating adhesive;
• the separator coating adhesive forms coating adhesive droplets covering transferring end surfaces of the transferring protrusions;
• a planar bottom roll rotates reversely relative to the adhesive accommodating device, such that a coating film is driven to move, and the coating adhesive droplets on the transferring protrusions drip onto the coating film to form incompletely covered coating layers on the coating film;
• and a dispensing control device including a first micro-adjustment platform, a first feed amount controller, a second micro-adjustment platform, and a second feed amount controller, wherein the relief roll is provided on the first micro-adjustment platform, and the adhesive accommodating device is provided on the second micro-adjustment platform;
• and wherein the transferring protrusions do not contact the separator.
