Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt-shaped carrier tape manufacturing apparatus for storing chemicals and fine electronic components in a storage recess formed by embossing and using the storage tape for transportation.

[0002]

2. Description of the Related Art As shown in FIG. 2, a belt-shaped carrier tape is a resin tape (made of PS or PET) a2 in which a storage recess b and predetermined articles (electronic parts, etc.) are stored in the storage recess b. An inspection hole c formed in the storage concave portion for inspecting whether or not it is present, and a sprocket hole d that is tandemly arranged laterally of the storage concave portion b for use in constant tape transport. Is.

The conventional apparatus for producing this band-shaped carrier tape is a conveying mechanism for moving the band-shaped film at a predetermined pitch, a heating mechanism for heating the embossed portion, and a heated portion for press working or vacuum forming with a die punch. It is provided with a forming mechanism for forming the storage recess b by processing, pressure forming, and the like, and for forming the inspection hole c and the sprocket hole d.

Various proposals have heretofore been made for concrete improvements in the molding mechanism of the manufacturing apparatus. For example, in Japanese Unexamined Patent Publication No. 11-333917, a die for embossing a storage recess and forming a feed hole (sprocket hole) by pressing, and a die for punching an inspection hole provided on the downstream side of the die. A method has been disclosed in which a die integrated with a die is used to reduce die cost and improve productivity.

Japanese Patent Laid-Open No. 2001-114208 discloses that
As a structure in which the upper and lower molds can be exchanged as a unit, a method capable of supporting a wide variety of products has been proposed.

Further, Japanese Patent Application Laid-Open No. 10-315311 discloses that after the embossing by pressure forming, the inspection hole and the sprocket hole are perforated.

[0007]

Each of the above-mentioned conventional apparatuses has made various proposals with the aim of improving productivity. Basically, however, as to the driving of a vertically operating die (for punching), No disclosure is given, only the use of conventional pressing equipment is shown. That is, it is presumed that, as a means for coping with the increase in speed, a crank mechanism is attached to the rotary drive source to realize the driving of the punching die.

By the way, when manufacturing other kinds of products in which the size of the recess of the carrier tape and the pitch of the sprocket holes are changed, it is necessary to change the mold (press type and compressed type). However, in the case of the device using the conventional crank mechanism, since the vertical stroke of the mold is constant, it is necessary to have a margin of stroke in order to cope with the mold change. Therefore, the long stroke of the die operation is an obstacle to speeding up for improving productivity.

Further, in the above-mentioned conventional apparatus, it has been proposed to integrally form a die for forming the storage recess and a perforation die, but since the formation of the storage recess is a press work by a ram die, it is produced. There is a limit to the speedup.

Therefore, the present invention proposes a change in the driving structure of the molding mechanism, and also proposes an apparatus for manufacturing a belt-shaped carrier tape in which the combination of molding means and the mold structure thereof are new.

[0011]

An apparatus for manufacturing a belt-shaped carrier tape according to the present invention comprises a tape feeding mechanism, a heating mechanism for a belt-shaped film provided in the middle of tape feeding, and a shaping mechanism for performing embossing and perforating. A servomotor that employs a molding mechanism in which a mold and a sprocket hole and a hole for inspecting holes are integrally incorporated into the mold part, and drives the mold part to reciprocally rotate at a set angle. It is characterized by what is done in.

Therefore, the rotation angle of the servo motor is set,
When a predetermined forward / reverse rotation is performed in a high-speed cycle, the mold part is driven with a stroke corresponding to the rotation angle, so the stroke of the mold part can be easily set by controlling the rotation angle of the motor. it can.

Further, in the present invention, particularly in the manufacturing apparatus, the upper mold part is operated with a stroke according to the rotation angle of the servomotor, and the lower mold part is preset different from the stroke of the upper mold part. It is the operation up to the top dead center.

Therefore, the upper mold can easily set the stroke of the mold part by controlling the setting of the rotation angle of the motor, while the lower mold can keep the top dead center constant, so that the upper mold can be set. Only the stroke of the part can be changed.

Further, according to the present invention, the embossing mold is for pressure molding, and is incorporated in the mold part integrally with the punching mold. Therefore, unless the molding and drilling operation operations are synchronized with each other. There is no inconvenience, and product accuracy is improved.
