2. Description of the Related Art Since a tape of this type relies on a sprocket system for feeding at the time of printing with a printing machine, cutting, lamination, mounting of chips, etc. Drill sprocket holes. The sprocket hole is perforated by setting a sprocket hole perforation section between a feeding mechanism (feeding roll) for supporting a roll of tape-like material and a winding mechanism (feeding roll), and a feed roller (pinch). With a constant intermittent feeding by a roller), holes are pierced at equal intervals on a row at the piercing portion at both edges in the width direction. The drilling of product holes in the product processing area between sprockets has been transferred to a dedicated machine. For this reason, two types of dedicated machines are required, so that the equipment cost rises, and the transfer work between apparatuses becomes troublesome.

[0003] In order to solve this problem, a perforated portion (perforated portion) for simultaneously processing a sprocket hole and a product hole is manufactured, and the perforated portion is provided between a feeding mechanism and a winding mechanism. A method of installation is proposed. By the way, in the case of TAB, TCP, PGA, BGA, and CSP, the wiring density tends to increase year by year, and a punching process of punching hundreds of holes in a required product processing area with a minimum shape of tens of μm is mainly used. Is occupied. Therefore, when the sprocket hole and the product hole are to be punched in a lump, a very high punch reaction force acts on all the fine punches, and a punch having a particularly fine diameter (shape) is obtained due to a balance between the punching pressure and the punch diameter. May be broken. In addition, there is a problem that the perforation pressure of the sprocket hole and the perforation pressure of the product hole temporarily concentrate in a required area, and the tape-shaped material is deformed and deformed. If the punch breaks, it is necessary to disassemble the perforated portion provided with the punch for the sprocket hole and the punch for the product hole to replace the punch, which requires cumbersome and complicated work.

The piston 23f has a layout in which the piston large-diameter portion 23f-1 projects a required amount into the second air chamber 800 in the first mode.
When compressed air is simultaneously supplied from the air path 701 and the third air path 901, the first air chamber 700 and the third air chamber 9
With the upward movement of the float piston 23g due to the pressure difference of 00 (Pascal's principle), the punch ram 23b is raised together with the protrusion V by the amount of protrusion V to slightly raise the punch holder 23a so as to approach the tape-shaped material B. This rise is the second mode (see FIG. 9).

The amount of protrusion of the piston large diameter portion 23f-1 into the second air chamber 800 can be adjusted by loosening the set screw 500 of the canopy 23e-3 by a required amount.
To lift the canopy 23e-3 constituting the upper wall portion of the cylinder 23e, and thereby the cylinder 23e

The height position of the punch holder 23a in the mode (see FIG. 9) can be set as required, and the second mode can be set according to various thicknesses of the tape-shaped material B. Of course, when the cylinder 23e is raised, the piston 23f also rises together with its sliding resistance that penetrates the canopy 23e-3 in a watertight manner, but by restricting the rise of the piston 23f by hand or the like, , Only the cylinder 23e can be raised relatively to the support 13 and the piston 23f.

The guide slot 23b-1 has a lower limit set on condition that the tape-shaped object B to be pierced is the tape-shaped object B having the minimum thickness. The amount V is set to 0.5 mm in the present embodiment. Therefore, for example, when the tape-shaped material B is thick, the thickness and the protrusion amount V (0.5 mm) are added.
It is necessary to raise the cylinder 23f. This is performed by adjusting the adjusting nut 23i. When the tape-shaped object B is thick, the pin 23f-3 is
Before the lower limit of b-1 is reached, the tape-shaped material B is sandwiched between the punch holder 23a and the fixed mold 33. Therefore, it receives the compressed air pressure to the first air chamber 700 directly,
There is a possibility that the tape-shaped material B may spread. In this case, the air pressure of the compressed air may be adjusted by a pressure adjusting valve connected to the first air path 701.

Function as an upstream clamper for preventing the tape-shaped material B from swinging due to friction with the fixed mold 44 at the time, and further, the tape-shaped material is removed by a punch holder (stripper) like a conventional punch holder (stripper). High-speed drilling of a sprocket hole is possible without continuing the holding state by the punch holder (stripper) until the punch is removed from the tape-like material by punching after being sandwiched.

[0049]

As described above, the present invention has the following advantages. (Claim 1) Each time a tape-shaped material is quantitatively fed from a feeding mechanism, a sprocket hole is pierced in a first punch piercing section, and then a second punch piercing section is controlled and moved according to a program to form a reference hole punch. Since the reference hole is drilled at the part, the reference hole is centered by the second centering camera, and the product hole is drilled at the second punch hole part based on the reference hole. Product holes can be drilled in the processing area with different pitches. Moreover, it is possible to center the sprocket hole drilled in the first punch punching section by the first centering camera, feed back the centering data, and adjust the intermittent feed amount to the first punch punching section, Drill sprocket holes with high accuracy. Of course, if the fine-diameter punch for product hole drilling (for product hole) is broken due to long-term use and must be replaced, it is sufficient to disassemble only the second punch hole and deal with it. When the hole is repaired by accident, only the hole (fixed type and movable type of the second punch hole) needs to be repaired, which is easy to deal with. (Claim 2) Since the tape-shaped material is tensioned by the first punch perforated portion and the clamper, and the second punch perforated portion perforates the product hole in a state where the wrinkles and the like are extended without bending, a high density is achieved. Can be drilled with high precision.
In this case, since the first punch perforation portion also serves as one of the clampers, there is no need to arrange a separate clamper to cope with the problem.
The device does not become large-scale and the equipment cost does not soar. (Claim 3) In addition, since the punch holder (stripper) keeps the state of approaching the tape-shaped object at the time of punching, the tape-shaped object is punched after the tape-shaped object is sandwiched by the punch holder (stripper). The holding time of a punch holder (stripper), such as a conventional punch die, which continues the holding state until the punch is removed from the object, does not delay the punching cycle, and the sprocket hole can be drilled at high speed. (4) A first aspect in which the punch holder at the lower end of the movable mold holds the tape-shaped object with the fixed mold, a second aspect in which the punch holder maintains the state of approaching the tape-shaped object during punching movement, the movable mold. Makes it possible to obtain the third mode in which it is separated above the tape-like material by one air cylinder using a float piston, which is much larger than when a servo motor is used as a driving source (a driving source). You can promise a very low price. . (Claim 5) In addition, the amount of rise of the press ram at the float piston, that is, the amount of rise of the punch holder, can be varied according to the thickness of the tape-like material, and the above-mentioned is independent of the thickness of the tape-like material. The effect of item 3 can be obtained.
