Abstract

PURPOSE:To obtain an apparatus capable of die-cutting TAB packages of plural sizes through a common die-cutting press die by using two planes of cut press dies of L-cut press die and turned L-cut press die and by position-controlling the two planes of cut press dies to actuate them alternately. CONSTITUTION:An apparatus is equipped with mutually facing L-cut press die 13 and turned L-cut press die 14 and with means for position-controlling these two planes of cut press dies 13, 14 to actuate said two planes of cut press dies 13, 14 alternately so that a TAB package 11 is die-cut from a TAB base film 12. For example, the TAB package is first die-cut by the L-cut press die 13 position-controlled in the left corner of the TAB package 11 in the TAB base film, while the TAB package 11 is attracted and fixed by a suction head so as not to bring about misregistration. Then, the right corner of the TAB package 11 is die-cut by a turned L-cut press die 14 position-controlled in the right corner so that the TAB package 11 is separated from the TAB base film 12.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a TAB package cutting device for punching TAB packages from a base film in the electronic component mounting industry.

Conventional technology T A B (Tape Autolated
Bonding is a technique for separating IC chips one by one from a film-like tape carrier and mounting them on a printed circuit board.

A conventional TAB package cutting device will be explained with reference to FIGS. 4 to 6.

In FIGS. 4 and 5, 1 is a TAB base film, 2 is a TAB package, 3 is a TAB package suction head, and 4 and 5 are upper and lower dies, respectively, of a TAB package punching press mold. 6 and 7 are cutting edges provided on the upper die 4 and the lower die 5, respectively, so as to face each other. 8 is a TAB base film pressing plate. As shown in FIG. 6, return guide rods 9 are provided at the four corners of the lower mold 5, and guide holes IO are provided in the portion of the upper mold 4 that opposes the rods 9.

The operation of the TAB package cutting apparatus configured as described above will be explained.

First, to prevent the TAB package 2 from shifting after cutting, use the TAB package suction head 3 to remove the TAB package 2.
While adsorbing the TA, the upper mold 4 and lower mold 5 move up and down while
The TAB package 2 is sandwiched between the B base film 1 and the TAB package 2 is punched out from the TAB base film 1 at once using the cutting edges 6 and 7.

Problems to be Solved by the Invention However, in the above configuration, the upper die 4 and the lower die 5 of the punching press die are dedicated to the size of the TAB package 2, so the TAB package cutting device is required for each package size. However, there was a problem in that the equipment cost would increase.

SUMMARY OF THE INVENTION In view of these conventional problems, it is an object of the present invention to provide an excellent TAB package cutting device that can punch out TAB packages of a plurality of sizes using a common punching press die.

Means for Solving the Problems In order to achieve the above object, the TAB package cutting device of the present invention uses two-sided cut press molds, an L cut press mold and an inverted L cut press mold, and the positions of these are controlled. TAB packages of various sizes can be cut from the TAB3 base film by alternately operating the TAB3 base film.

Effect of the Invention With the above-described configuration, the present invention can punch out TAB packages of different package sizes without using a number of dedicated cutting devices. , can be performed with one type of cutting device.

EXAMPLE Hereinafter, a TAB package cutting apparatus according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3.

Figure 1 is a plan view of the TAB package in the L-cutting process using the cut press type of the TAB package cutting device, and Figure 2 is a plan view of the TAB package in the reverse L-cutting process using the inverse L-cut press type of the TAB package cutting device. be.

In Figures 1 to 2, 11 is a TAB package;
12 is a TAB base film, 13 is a T4 AB cutting device of the cut press type, and 14 is a TAB package cutting device of the reverse L cut press type. 15.
Reference numerals 16 are cut-press type holding plates for the TAB base film 12, respectively.

Figure 3 shows inverted L-cut press type 1 of TAB packaging equipment.
4 is an exploded perspective view showing details of the TAB package 11 and the TAB package suction head 17.

In FIG. 3, 17 is a TAB package suction head, 18 is a return guide rod, and 19 is a guide hole for guiding these guide rods 18. The inverted L-cut press mold 14 is composed of an upper die 14a and a lower die 14b, and the TAB base film 12 is formed by an inverted L-shaped cutting edge 20 of the upper die 14a and an inverted L-shaped cutting edge 21 of the lower die 14b.
It is designed to cut. The cut press mold 13 shown in FIG. 1 has a similar structure. These two-sided cut press molds are controlled by a position control means (not shown) so that their positions can be changed in various ways.

First, in order to prevent the TAB package 11 from shifting after cutting, the TAB package suction head is used to
While fixing the AB package 11 by suction, as shown in FIG. 1, the left corner of the TAB package 11 in the TAB base film 12 is punched out using a cutting press die 13 whose position is controlled. This L-cut press mold 13 is designed to cut after a pressing plate 15 presses the base film 12 before punching. After punching with the L-cut press die 13 is completed, as shown in FIG.
Punch out the right corner of the TAB package 11 with TAB
The package 11 is separated from the TAB base film 12. In this way, from the TAB base film 12 to the TA
The B packages 11 are punched out one by one.

As described above, according to this embodiment, the base film 1 is alternately cut by position control of the two-sided cut press molds 13 and 14.
By cutting 6 TAB packages 11 from 2, it is possible to punch out TAB packages of different package sizes using only one type of cutting device.

Effects of the Invention As described above, the present invention provides two-sided cut press molds, an L-cut press mold and an inverted L-cut press mold, while controlling their positions.
Since the TAB package is separated from the base film, it is possible to punch out TAB packages of different package sizes using one type of cutting device.
