Description

Method for Punching IC Card sheet in One Direction and Punching Apparatus there of}

Field of invention

The present invention relates to a method of punching a contactless IC card sheet and a punching mechanism thereof. More specifically, the present invention relates to a method of punching a contactless IC card sheet that continuously punches in one direction in punching a sheet of a contactless IC card, and two punch blades having different shapes as the punching mechanisms are formed so that different types of IC cards are formed. The present invention relates to a drilling tool capable of drilling two sheets in different shapes at once.

Background of the Invention

As a storage element capable of recording and storing various data, a non-contact type IC card that transmits and receives information by radio waves is widely used in various fields for various functions. This is because the non-contact type IC card is very convenient in terms of use, and is also very excellent in terms of its function and is rapidly developing. Such a contactless IC card can be easily found around us include a pass card such as a Seoul subway card or a bus card.

Such a contactless IC card is formed by inserting an IC chip into a sheet for forming a card and winding a wire serving as an antenna. However, in order to insert an IC chip, the sheet must first be punched. In the conventional method of punching the IC card sheet, a punching mechanism provided with a mold is provided on the upper and lower sides of the sheet having one sheet and facing each other. In addition, the punching mechanism drills a plurality of holes at the same time by providing a plurality of punches in the upper and lower portions.

In the conventional drilling method, when one sheet is transferred between the upper and lower punches, the upper punch having a plurality of punch blades is lowered, and the lower punch having a plurality of punch blades corresponding to the upper punch is raised to raise the sheet. Perforate. In this case, the sheet is stressed by the upper and lower punch blades formed with a plurality of punch blades, and thus the holes formed in the sheet have an error in position. This is a very big problem considering that an error of 1 mm or more in a hole formed in a non-contact IC card is directly connected to a defective product. In addition, when changing the pitch (pitch) in the plurality of punch blades, the upper and lower punches need to be replaced, thereby producing a new mold and the production cost naturally increases. In addition, since the wire winding work and the IC chip attaching work are performed on one line, it takes a lot of work time, and if a problem occurs in one process, the whole process must be stopped so that the work time is delayed and production efficiency Is reduced.

In order to solve this problem, the present invention is provided with two sheets of different resins first, and two at a time by a method of punching in one direction by using a punching mechanism formed with two punch blades of different shapes according to the present invention. By drilling two sheets in different shapes, the stress generated by the upper and lower punches is reduced, and the incidence rate of defective products is significantly reduced by forming continuous and accurate holes. As the two sheets are separated from each other during the wiping process, the work time is shortened and the productivity of the non-contact IC card sheet in one direction and its drilling mechanism can be shortened.

SUMMARY OF THE INVENTION An object of the present invention is a method for drilling a non-contact IC card sheet of a non-contact IC card sheet which improves productivity by reducing stress applied to a sheet of an IC card at the time of drilling and thereby significantly reducing a defective rate by using a punch for drilling in one direction. It is to provide apparatus

Another object of the present invention is to provide a one-way punching method of the non-contact IC card sheet and the punching mechanism capable of realizing continuous and accurate punching by releasing the punched sheet after punching by using a punching mechanism provided with a release pin. .
