Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic component taping apparatus that performs taping suitable for supplying electronic components, particularly for supplying electronic components having comb-shaped leads to a mounting apparatus.

Conventionally, the flat package IC shown in Fig. 1,
The following two ICs (hereinafter referred to as electronic components) have comb-shaped leads and are relatively small in shape, such as the mini package IC and SOIC shown in Figure 2.
It was supplied by the standard method. That is, as shown in FIG. 3, the electronic components are arranged in a vertical direction and are fed into a magazine from which they are taken out one by one, or as shown in FIG. There are two methods of supplying carrier magazines in a loaded manner.

However, although the magazine supply shown in Fig. 3 can supply parts relatively reliably by using a push rod, etc., it has the disadvantage that the number of parts stock cannot be increased in general, and the carrier magazine supply shown in Fig. 4 can supply the parts relatively reliably. Although stable, it requires a large carrier magazine for the electronic components, and automatic feeding of this carrier magazine requires a large space and a complicated feeding device.

The present invention aims to eliminate the above-mentioned conventional drawbacks and provide an electronic component taping device capable of continuous and stable supply.

An embodiment of the present invention will be described below with reference to FIGS. 5 to 14.

5 and 6 show taping of an electronic component according to an embodiment of the present invention. Reference numeral 1 denotes a tape, and this tape 1 has holes 2 provided therein. An adhesive tape 5 is fixed to one side of the tape 1, and in the hole 2 part, as shown in FIG. Side 6 is now exposed. The electronic components 3 are loaded one by one on the adhesive surface. Further, the tape 1 is provided with a through hole 4 for loading electronic components 3 thereon.

FIG. 7 schematically shows the entire electronic component taping device, in which a component supply section 8, a component separation section 9, a tape winding section 10, and a taping section 11 are provided on the main body 7. Then, as shown in FIG.
4 and is pressed against the adhesive surface 6 of the tape 1 of the tape winding section 10 by the cylinder 15 of the taping section 11, and the electronic component 3 is fixed to the tape 1 to complete the taping.

Next, the configuration of the component supply section 8 will be explained in detail.

First, in FIGS. 9 and 10, the magazine 12 is easily fixed to the base 16, and the holding plate 1 is mounted on the base 16.
7, 18 and guide blocks 19, 20 are attached. Further, a guide 21 is provided to prevent the electronic component 3 from flying out from the magazine 12.

The base 16 is operated by a motor 25 through a Geneva gear 24 through a rack 22 and a pinion 23.

Next, the operations will be explained in order.

When the magazine 12 is set using the presser plates 17 and 18 fixed to the base 16 and the guide blocks 19 and 20, a notch is provided in the guide 21 at the tip of the magazine fixed at position A so that the electronic component 3 can pass through. Since the base 16 is inclined, the electronic components 3 flow out of the magazine 12 and enter the chute 26. When the electronic parts 3 in the magazine 12 at position A are exhausted, the detector 27 of the separating section 9 is activated, and the base 16 moves by one pitch, so that the magazine 12' at position B comes to the position A. When the base 16 moves, the notch portion of the guide 21 is guided by a component shutter 28 so that the electronic component 3 does not fly out.

Repeating the above operations, when the base 16 reaches the right end, the detector 29 is activated and the motor 25 reverses the rotation and moves to the left. Through the above-described operations, parts are continuously supplied from the magazine 12 to the separating section 9. Also, regarding replacing the magazine 12,
Since the base 16 does not move during machine operation, replacement is easy.

Next, the configuration of the component separating section 9 will be explained in detail.

First, in Figures 11 and 12, frame 3
A component shutter 28, a chute 26, and a cylinder 31 are attached to the chute 26, and a cover 32 is attached to the chute 26 to prevent the electronic component 3 from flying out. A component stopper pin 14, a component retainer 34, and a spring 35 are attached to the cylinder 31. The component shutter 28 is connected to the cylinder 36. The chute 26 can be replaced more easily than the frame 30.

Next, the operations will be explained in order.

The electronic components 3 flowing out from the component supply section 8 are stopped by the component shutter 28, but the cylinder 36 works to push down the component shutter 28 and the electronic components 3 flow into the chute 26. Electronic parts 3
is stopped by the component stopper pin 14 pushed up by the cylinder 31. The operation of separating electronic components one by one from this state will be explained.

When the component stopper pin 14 is pressed down by the cylinder 31 in order to separate the electronic components, the component holder 34 presses the next component and stops the flow. The component holder 34 is also lowered until the component stopper pin 14 is completely removed from the groove of the chute 26, so that when the component holder 34 hits an electronic component, the built-in spring 35 causes the component holder 34 to escape. The separated parts are positioned by a stopper 37 at the tip of the chute and are pressed against the tape 1 to be taped. The above operations are repeated to separate the electronic components and enable continuous supply.
Further, when the supply from the magazine 12 runs out, the detector 27 operates to operate the component supply section 8 to supply the electronic component 3. Furthermore, the electronic components 3 are separated by operating the cylinder 31 by the action of the detector 38. These operations reliably separate the electronic components 3 one by one and enable continuous supply.

Next, the configuration of the tape winding section 10 will be explained in detail.

In FIGS. 13 and 14, a tape reel 40 and a take-up reel 41 are set on the base 39,
A sprocket 42 and tape feed guides 43 and 4 that feed the tape 1 from the tape reel 40 at a fixed pitch.
4 and a tension roller 45 for guiding and tensioning the tape 1. Further, a presser wheel 46 is provided between the sprocket 42 and the tension roller 45 to prevent the tape from sagging. The take-up reel 41 has the take-up reel 4
A roller 47 that transmits rotation is in contact with the tape 1 and winds the tape. Also tape feed guide 4
A cylinder 15 is provided between 3 and 44 to press the electronic component 3 that has come to the tip of the chute 26 of the separation section 9 against the tape 1 to perform taping.

Next, the operations will be explained in order.

As shown in FIG. 13, the tape 1 is guided by the tape reel 40, passes through the tension roller 45, and is guided by the tape feed guides 43 and 44, and is moved to the sprocket 42.
When one electronic component is separated and flows to the tip of the chute 26 of the separating section 9 while being sent by the winder and wound onto the take-up reel, the detector 38 of the separating section 9 is activated and the cylinder 15 moves forward. The operation is performed to press the tape 1 against the electronic component 3. At this time, the adhesive surface 6 of the tape 1 is attached to the cylinder 15 on the electronic component 3.
The tip of the tape is pressed and adhered to the tape 1. When the cylinder 15 moves backward, the tape 1 is moved to the tape presser 48.
Due to the rotation of the sprocket 42, it is separated from the separating section 9 and is fed at a constant pitch. At this time, the roller 47 and tension roller 45 are always driven by the motor 49.
It is rotating due to Note that the rotations of the roller 47 and the tension roller are controlled by a torque limiter 50.

By repeating the above operations, it is possible to tape electronic components continuously at a constant pitch.

In addition, in the description of the above-mentioned embodiment, taping of an electronic component having a comb-shaped lead was described as an electronic component, but an electronic component having other comb-shaped leads may be used. It goes without saying that various other modifications can be made without departing from the gist of the present invention.

As explained above, the present invention guides a tape at a predetermined interval to separated electronic components and presses the tape to adhere the electronic component to the adhesive surface of the tape, so that the component can be moved. Compared to the method of fixing components to tape, parts can be positioned accurately and easily, and electronic components with comb-shaped leads can be easily and reliably supplied continuously and stably, resulting in significant labor savings and cost reductions. The effect is great as it allows you to
