Description

Technical Field

[0001] This utility model relates to the technical field of battery electrode production equipment, specifically to a modular electrode coating head quick-change device. Background Technology

[0002] In the production of battery electrodes, a slurry needs to be coated on the electrode substrate. The slurry forms a thin film on the surface of the electrode to improve its performance. Currently, the coating production of battery electrodes is carried out using a coating die. The coating die has a pressure equalization chamber inside and a coating flow channel at the front end of the coating die. The uniformity of the coating surface density, the consistency of the transverse thickness, and the accuracy are mainly determined by the flow rate and flow volume of the slurry before coating. The flow rate and flow volume of the slurry are mainly determined by the cavity pressure of the pressure equalization chamber and the gap of the coating flow channel.

[0003] Patent publication number: CN109759284A, relates to a coating die head for a coating machine that facilitates quick and accurate replacement of gaskets and improves coating accuracy. It includes an upper die, a lower die, and a gasket for cooperative use. The upper die includes a reference die, a disassembly die, and a locking mechanism. The reference die is fixedly assembled at a designated reference position on the lower die. The locking mechanism is fixedly assembled on either the reference die or the lower die. The disassembly die is pressed tightly against the reference die by the locking mechanism. The gasket is fixedly clamped between the upper lip of the disassembly die and the lower lip of the lower die. The upper die of this invention has a split structure. The reference die provides precise reference positioning. The disassembly die, through the locking operation of the locking mechanism, enables repeatable, rapid, and accurate alignment and installation. The disassembly die has high installation accuracy and is quick to operate. Using this invention, the gasket replacement operation only takes 15-30 minutes, which is only one-fifth to one-sixth of the disassembly and assembly time of a traditional integrated coating head, significantly improving installation efficiency.

[0004] However, the solution disclosed in this patent cannot speed up the disassembly and replacement of the entire coating die head and mounting platform.
