Abstract

PURPOSE:To avoid the bad influence of a shock, a vibration or the like by a tape cutting operation and to obtain the stable suction state of an electronic component in a tape cutting apparatus when the electronic component by a taping system is mounted. CONSTITUTION:The title cutting apparatus is provided with the following: a tape delivery means which feeds a tape 1 intermittently; a rotary blade 14 which is provided with a plurality of edges on the outer circumference of a cylinder; and a fixed blade 13 which has been installed so as to be faced with the rotary blade 14. The rotary blade 14 and the tape delivery means are constituted so as to be synchronized; the tape 1 can be cut at a required timing; and it is possible to avoid the bad influence of a shock, a vibration or the like by a tape cutting operation when a mounting head 7 sucks a chip component 8.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cutting taping tape for electronic parts.

0002

2. Description of the Related Art In recent years, when electronic components are mounted on printed circuit boards, taping type electronic components are often used.

[0003] A conventional tape cutting device of this type will be described below with reference to the drawings. Figure 2 shows a mounting machine for chip-type electronic components (hereinafter referred to as chip components).
The tape 1 containing the tape 1 is fed one pitch at a time by a supply lever 2. The supply lever 2 is driven via the lever 3 by a cam 6 connected to a motor 4 by a belt 5. Mounting head 7 is tape 1
The chip component 8 is taken out, the printed circuit board 10 is mounted on the
5 and a rotating blade 14 connected to the belt 16 by a belt 16. The cut tape pieces 17 are stored in a cut piece box 18.

[Problems to be Solved by the Invention] However, in the above configuration, the tape is constantly cut regardless of the tape feeding, and when the mounting head 7 adsorbs the chip component 8, the impact caused by the tape cutting occurs. , the vibrations are transmitted to the chip component supply unit, and the suction state of the chip component 8 becomes unstable.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a tape cutting device that avoids the negative effects of shock, vibration, etc. caused by cutting the tape and provides a stable adsorption state for chip components.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a tape feeding means for feeding the tape intermittently;
It has a plurality of blades on the outer periphery of a cylinder and is equipped with a rotary blade that is rotatably supported, and a fixed blade that is provided opposite to the rotary blade and has a gap between it and the rotary blade that allows tape cutting. , the rotary blade is connected to the tape feeding means so that the rotary blade and the tape feeding means are synchronized.

[0007]

[Operation] In the present invention, in the above structure, the rotary blade and the tape feeding means operate in synchronization, so that the tape can be cut at a necessary timing (such as after the mounting head picks up the parts). Therefore, when the mounting head picks up the chip component, it is possible to avoid the negative effects of shock, vibration, etc. due to tape cutting.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the tape cutting device of the present invention will be described below with reference to FIG. Note that the same numbers are used for the same constituent members as those explained in the conventional example.

FIG. 1 shows a tape cutting device for a pre-cut cassette in a mounting machine for chip components 8, in which a tape 1 containing chip components 8 is fed one pitch at a time by a supply lever 2. The supply lever 2 is driven via a lever 3 by a cam 6 connected to a motor 4 and a belt 5. The mounting head 7 picks up the chip parts 8 from the tape 1.
The tape 1 is taken out and placed on a printed circuit board 10 on an XY table 9, and the empty tape 1 is sent to a cutter 12 where it is cut by a fixed blade and a rotary blade 14 connected to the motor 4 by a belt 19 and rotated. Ru. At this time, the mounting angle of the rotary blade 14 is set to the timing at which the mounting head 7 adsorbs and lifts the chip component 8 and then cuts the tape. The cut tape pieces 17 are then sucked up by a dust collector 20.

It goes without saying that the mounting angle of the rotary blade 14 can be arbitrarily set as long as the timing at which the mounting head 7 picks up the chip component 8 is avoided.

[0011]

As is clear from the above description of the embodiments, according to the present invention, the operations of the rotary blade and the tape feeding means are synchronized, so that the tape can be cut at the required timing. Therefore, when the mounting head picks up the chip component, it is possible to avoid the adverse effects of shock, vibration, etc. due to tape cutting, and a stable suction state can be obtained, thereby improving the chip component pick-up rate by the mounting head.
