Abstract

PROBLEM TO BE SOLVED: To prevent generation of a cutting error by guiding an unnecessitated carrier tape to a cutter without error by a method wherein the cutter, which cuts the unnecessitated carrier tape after taking out an electronic part, is provided and a guide plate is provided between a part feeding cassette and the cutter. SOLUTION: A cylindrical carrier tape guide 10 is provided between a part feeding cassette 7 and a cutter 5. A guide plate 11 is provided in the center part of the carrier tape guide 10. The guide plate 11 is provided with a plurality of segments 11b which are rectangularly divided by slits 11a, and a folding piece 11c, to be used for mounting, is provided on the opposite side of the segment 11b. It is desirable that the width of the segment 11b is wider than the width of a carrier tape 8. A segment 11b1, on which the tip of the carrier tape 8 comes in contact, becomes loose and the stepping formed between the segment 11b1 and the adjacent segment 11b controls and guides the left and right positions of the carrier tape.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component mounting apparatus, and more particularly to a guide plate for guiding an unnecessary carrier tape to a cutter of the electronic component mounting apparatus.

[0002]

2. Description of the Related Art Conventionally, an electronic component mounting apparatus has been used in which electronic components are housed in a carrier tape, and the components are taken out from the carrier tape and sequentially mounted on a printed wiring board. This type of electronic component mounting apparatus incorporates a cutter that cuts into short pieces to make it easier to process an unnecessary carrier tape. However, since the cutter incorporated in the conventional electronic component mounting device cuts the unnecessary carrier tape, when the cutter moves to the position of the tape, before the tip of the tape enters between the blades, Sometimes I couldn't cut it without touching the top and escaping laterally to get between the cutters.

[0003]

Therefore, the problem to be solved by the present invention is to reliably guide an unnecessary carrier tape to a cutter incorporated in an electronic component mounting apparatus,
An object of the present invention is to provide an electronic component mounting device that is free from cutting mistakes.

[0004]

The electronic component mounting apparatus according to the first aspect of the present invention is provided with a component supply cassette around which a carrier tape containing electronic components is wound, and becomes unnecessary after the electronic components are taken out. A cutter that cuts the carrier tape is provided, and a guide plate is provided between the component supply cassette and the cutter, so that the unnecessary carrier tape is reliably guided to the cutter and cut reliably.

According to a second aspect of the present invention, there is provided an electronic component mounting apparatus according to the first aspect, wherein the guide plate has a plurality of strip-shaped segments divided by slits. A step is formed between the segment touched by the carrier tape and the adjacent segment, and the lateral direction of the carrier tape is regulated.

BEST MODE FOR CARRYING OUT THE INVENTION

Preferred Embodiments Preferred embodiments of the present invention will be described below with reference to FIGS. 1 to 3. The electronic component mounting apparatus 1 mounts an orthogonal robot 2, a head 3 movably supported by the orthogonal robot 2 in the XY directions, a component supply unit 4, a cutter 5 movable in the X direction, and electronic components. It includes a conveyor 6 for carrying a printed wiring board 9 to be printed.

Then, the orthogonal robot 2 is driven by a drive mechanism (not shown), so that the head 3 is moved onto the component supply cassette 7 mounted on the component supply section 4. Here, the suction means (not shown) connected to the component suction nozzle 3a of the head 3 operates to suck and hold the electronic component 8a in the carrier tape 8 mounted in the component supply cassette 7.

From this state, the orthogonal robot 2 is driven and controlled by the drive control means (not shown),
The head 3 is moved onto the printed wiring board 9 to be mounted on the conveyor 6, and the electronic component 8a is mounted on the printed wiring board 9. At this time, the cutter 5 is driven and controlled by a drive control means (not shown) to move below the component supply cassette 7 mounted on the component supply unit 4. When the cylinder 5a of the cutter 5 operates, the movable blade 5b1
However, the unnecessary carrier tape 8 is cut by sliding on the fixed blade 5b1. By the above operation, one electronic component is mounted on the printed board, and thereafter, this operation is repeated. Then, after the last electronic component is mounted on the printed wiring board 9, the conveyor 6 is operated to convey the printed wiring board 9 to the next step.

Further, as shown in FIG. 2, a tubular carrier tape guide 10 is provided between the component supply cassette 7 and the cutter 5 of the electronic component mounting apparatus 1 having such a structure,
A guide plate 11 is provided at the center of the carrier tape guide 10. As shown in FIG. 3, this guide plate 11 has a segment 11b divided into a plurality of strips by slits 11a.
And a folding piece 11c provided for attachment is provided on the opposite side of the segment 11b. Segment 11b
The width of the tape is preferably wider than that of the carrier tape 8.

Then, the segment 11b1 touched by the tip of the carrier tape 8 is bent, and the step formed between the segment 11b1 and the adjacent segment 11b is
The left and right positions of the carrier tape 8 are regulated and guided. As a result, when the cutter 5 moves, even if the carrier tape 8 comes into contact with the blade 5b of the cutter 5 and a lateral force is applied to the carrier tape 8, the carrier tape 8 has a function of suppressing lateral escape. The carrier tape 8 can be reliably put into the blades 5b1 and 5b2 of the cutter.

[0011]

As described above, according to the present invention, it is possible to provide an electronic component mounting apparatus which can surely guide an unnecessary carrier tape to a cutter and ensure the cutting.
