Description

Strip metal layer film punching device and method thereof

Technical field

The invention relates to a metal punching device and a method thereof, in particular to a strip metal layer film automatic punching device and a method for forming a metal pattern product by punching a strip metal layer film using the device.

Background technique

Metal is a non-elastic material. Conventionally, the stretching of ordinary metal may cause fracture or other permanent deformation, and in the ultra-thin state of the metal (the thickness of the metal layer is between 20 nm and 200 nm) and in a serpentine configuration. In the case of the metal itself, it can be stretched and returned to its original state after stretching, but the metal of this thickness is very fragile and easily broken. By using the film as a supporting material for the metal, the metal is realized. Stable under this thickness. At the same time, the metal film is made into various desired patterns by the preparation process, and can be used as a soft, stretchable, folded ultra-thin circuit, which can be applied to the production of functional electronic skin.

On the one hand, the conventional metal pattern preparation process uses a chemical method - photolithography, which requires a total of about 20 steps. At least 4 of these steps cannot be applied to industrial roll to roll. Each set of patches (up to 6 pieces) of the process requires 2 skilled workers for 2 days, and the yield is less than 80%. This process is inefficient, expensive, low yield, and not suitable for industrial mass production.

On the other hand, since the metal layer film is relatively thin and soft in texture, the metal pattern product is produced by the inner peripheral punching and shearing method of the punching and the through hole in the prior stamping technique, and the metal layer is easily cut in the punch and the through hole. In the case of a film, the instantaneous impact pressure causes the surface of the flexible film to stretch beyond its breaking force, thereby destroying the metal layer film; while the conventional punch punches the underlying material, the punched scrap or film product may be cut. After cutting, it jumps out from the edge of the punch or is adsorbed on the punch, and the production of the line cannot be realized, and the surface of the processed metal layer film is prone to wrinkles, thereby causing the scrapping of the plate.

Due to the frequent use of the vacuum pump on the production line, and the processing of a single product is very short, the pumping efficiency of the air chamber is required to be very high, so the volume of the convex cavity 332 is small enough to process the product as needed. Size and shape, need to control the number of adsorption pores and pore size: the number of adsorption pores should not be too much, the pore size is within 3 mm.

The moving distance of 33 and the pressure of the new film (with a thickness of 0.05 to 0.3 mm) by the vacuum hole punch 33 are monitored by the sensor to make the vacuum hole convex The die 33 moves downward along the punching guide bar 32 at a position just in contact with the upper surface of the new film, the vacuum pump is turned off, the compressed air is turned on by the changeover switch, and the metal pattern product adsorbed on the vacuum hole punch 33 is smoothly adhered to the new film. The new film thickness is within 0.05 to 0.3 mm.

After the above process is completed, the punching power 31 is again activated, and the punching guide bar 32 is returned with the vacuum hole punch 33 to return to the initial vertical position. At this time, the moving power 21 is activated, and the pressing member 3 is horizontally moved from the bonding portion 9 to the immediately above the punching portion 8, all in the initial state, and the next operation is continued. Pipeline operations can be achieved by repeating them one after the other.
