Problems solved by technology

However, when metal foil is press-formed using a ceramic roll with recesses formed on its peripheral surface, a large number of cracks, chipping, cracks, etc. are generated on the peripheral surface of the ceramic roll, making it impossible to continuously press-form the metal foil.

Embodiment 1

[0097] A Nb:YAG laser was installed as a laser oscillator in a laser processing apparatus (manufactured by Spectra-Physics Co., Ltd.). The intensity of the laser light output from the processing head was set to 23 μJ per irradiation. In addition, adjust the condenser lens and focal length, and set the imaging magnification of the processing head to 16 times. That is, the imaging size of the processing head is 1 / 16 times the opening of the mask for laser processing. As a mask for laser processing, a mask having a thickness of 0.3 mm and a size of 22 mm×22 mm in size of 22 mm×22 mm in size of 22 mm×22 mm stainless steel plate (SUS304) was subjected to electrical discharge machining to form a substantially rhombic laser passing hole. The diamond-shaped opening diameter (long diagonal length) of the laser passing hole is 0.32 mm. The short diagonal length is 0.16mm.

Embodiment 2

[0102] In addition to using cemented carbide rollers (manufactured by Fuji Daisu Co., Ltd., diameter 50mm, width 100mm, Rockwell hardness: HRA90.0 on A scale, flexural strength: 3.1GPa, containing tungsten carbide particles and cobalt (bonding) Agent)) except that, it carried out similarly to Example 1, and produced the roll for metal foil processing of this invention.

[0103] Two of the metal foil processing rollers are installed on the metal foil processing device 10, except that the pressure on the crimping nip is changed from about 14.7kN·cm (1500kgf / cm) to about 9.8kN·cm (1000kgf / cm) Except that, it processed similarly to Example 1, width 80mm, and the tough copper foil of thickness 26 micrometers. Protrusions corresponding to the recesses of the metal foil processing roller were formed on the surface of the processed copper foil. The average height of 10 convex portions measured with a laser microscope (VK-9500) was 6.5 μm. 100 m / roll, a total of 10 rolls of 1000 m co...

Embodiment 3

[0105] In addition to using a hard roll (manufactured by Fuji Daisu Co., Ltd., diameter 50mm, width 100mm, Rockwell hardness: HRA89.0 on the A scale, flexural strength: 3.3GPa, containing tungsten carbide particles and cobalt (binder) ) except that the roll for metal foil processing of the present invention was produced in the same manner as in Example 1.

[0106] Two of the metal foil processing rollers are installed on the metal foil processing device 10, except that the pressure on the crimping nip is changed from about 14.7kN·cm (1500kgf / cm) to about 9.8kN·cm (1000kgf / cm) Except that, it processed similarly to Example 1, width 80mm, and the tough copper foil of thickness 26 micrometers. Protrusions corresponding to the recesses of the metal foil processing roller were formed on the surface of the processed copper foil. The average height of 10 convex portions measured with a laser microscope (VK-9500) was 6.3 μm. Furthermore, processing was performed on 100 m / roll, 20 ro...

Abstract

A roller for machining a metal foil has a plurality of recesses formed in the circumferential surface of a roller containing a metal material having a Rockwell hardness HRA of 81.2-90.0 in A scale and a deflecting strength of 3GPa-6GPa. When a metal foil is pressed using this metal foil machining roller, protrusions in substantially uniform shape having dimensions from several microns to several tens of microns can be formed efficiently on the surface of the metal foil in an industrial scale.

Description

technical field [0001] The present invention relates to a roll for metal foil processing. More specifically, the present invention mainly relates to improvement of a metal material constituting a roll for metal foil processing having a plurality of recesses formed on the surface. Background technique [0002] Conventionally, in order to form protrusions on the surface of a metal foil having a thickness of several tens of micrometers, a plating method, an etching method, or the like is generally used. However, when using these methods in every 1cm 2 When forming tens to hundreds of protrusions with a size of micron units on the surface of a metal foil, it is necessary to perform precise processing including multiple steps, requiring complicated operations, and taking a long time. Even so, the reject rate cannot be sufficiently reduced. Disposal of waste liquid accompanying the use of plating liquid, etching liquid, etc. is also a problem. In addition, the bonding strength...
