Problems solved by technology

[0004] This readjustment becomes a factor of loss of time, resulting in a decrease in the operating rate of the device
In addition, the high frequency of adjustments leads to instability in the coating process, which may lead to a decrease in the quality of the final product.

Embodiment Construction

[0035] figure 1 It is a figure which shows the whole structure of the coating apparatus which concerns on one Embodiment of this invention. It should be noted that, in figure 1 In each of the following drawings, in order to clarify the directional relationship, an XYZ rectangular coordinate system is shown in which the Z-axis direction is the vertical direction and the XY plane is the horizontal plane. In addition, in figure 1 In the subsequent drawings, for ease of understanding, the size or quantity of each part is exaggerated or simplified as required.

[0036] The coating device 1 conveys a strip-shaped base material along a predetermined conveying direction, and at the same time discharges a coating liquid containing an active material material on the surface of the base material, thereby coating a coating film on the base material, and by The drying section dries the coated film to manufacture electrodes for lithium-ion secondary batteries. The coating apparatus 1 is...

Abstract

According to the coating device and coating method provided by the present invention, the drying time can be changed without changing the conveying speed to cope with various coating conditions, and the coating can be formed on the base material with excellent operation rate and stable quality. membrane. The coating device of the present invention includes: a conveying part for conveying a long strip-shaped base material along the longitudinal direction of the base material; an application part for applying a coating film to the substrate conveyed by the conveying part a material; a drying unit that heats the base material transported from the coating unit by the transport unit to dry the coating film; and a path length changing unit that changes the length of the transport path of the base material in the drying unit.

Description

technical field [0001] The present invention relates to a coating device and a coating method. While conveying a long strip-shaped base material along its longitudinal direction, a coating film is applied to the base material by a coating section, and a drying section is used to form a coating film. The base material of the coating film is heated to dry the coating film. Background technique [0002] As such a coating device, for example, the device described in JP 2014-184364 A is known. In this device, the base material (for example, metal foil) unwound from the uncoiler is conveyed to the winder by conveying rollers, and is wound up in the winder. In this way, after the coating film of the electrode material (for example, paste containing an active material) is coated on the base material conveyed in the longitudinal direction, the coating film is dried by the drying section. Through such a series of coating steps, a coating film is formed on the base material. [0003...
