Belt metal layer film punching device and method thereof

Abstract

The invention discloses a belt metal layer film punching device and a method thereof. The device comprises a base, a vacuum pump, a moving assembly, a punching assembly, a vacuum hole supporting plate, a power wheel disc, a rotating wheel disc and a pressure wheel disc. The punching assembly comprises a punching power source, punching guiding rods and a vacuum hole male die. A cutting die is arranged on the vacuum hole male die, and first adsorption holes are formed in the inner surface of a sealed area of the vacuum hole male die. The surface of the vacuum hole supporting plate is provided with female dies, positioning sliding grooves and second adsorption holes. The punching method of the device comprises the steps that a belt metal layer film is punched through the vacuum hole male die; a cut metal pattern product is adsorbed on the surface of the vacuum hole male die, and waste materials after punching are adsorbed through the vacuum hole supporting plate; and the product is stuck onto a new film through adsorptive transfer. According to the belt metal layer film punching device and the method thereof, the cut metal pattern product is subjected to adsorptive control and transferring, and it can be guaranteed that the cut product is prevented from jumping out of a punch, so that the production operation of an assembly line is achieved, and the flatness of the product surface is guaranteed.

Description

technical field [0001] The invention relates to a metal punching device and a method thereof, in particular to an automatic punching device for a band-shaped metal layer film and a method for punching a band-shaped metal layer film to form a metal pattern product by using the device. Background technique [0002] Metal is a non-elastic material. Under normal circumstances, the stretching of ordinary metals will cause fracture or other permanent deformation, and in the ultra-thin state of the metal (the thickness of the metal layer is between 20nm-200nm) and in a serpentine configuration In this case, the metal itself can be stretched and can return to its original state after stretching, but the metal of this thickness is very fragile and easy to break. By using the film as the supporting material of the metal, the metal in the Stable at this thickness. At the same time, through the preparation process, the metal film can be made into various required patterns, which can be...

Problems solved by technology

At least 4 of them cannot be applied to industrial roll transfer printing (rolltoroll)

This process requires 2 skilled workers to spend 2 days per group of patches (up to 6 pieces), and the yield is less than 80%.

This process is inefficient, expensive, has low yields, and is not suitable for industrial mass production

[0004] On the other hand, because the metal layer film is relatively thin and soft in texture, if the metal pattern product is produced by punching and shearing the inner circumference of the punch and the through hole in the existing stamping technology, it is easy to cut the metal layer between the punch and the through hole. When the film is cut, the impact pressure generated instantaneously causes the surface of the flexible film to stretch beyond its breaking tension, thereby destroying the metal layer film; while the traditional way of cutting the underlying material with a punch, the waste or film product being punched may be damaged during shearing. After cutting, it jumps out from the edge of the punch or is adsorbed on the punch, which cannot realize the production of the assembly line, and the surface of the processed metal layer film is prone to wrinkles, resulting in the scrapping of the plate
