Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component information reader for reading information indicating the type and remaining amount of electronic components continuously mounted on a tape for supplying electronic components to an automatic assembly machine or the like.

[0002]

2. Description of the Related Art A tape carrier system is one of the forms of supplying electronic parts to an automatic assembly machine. In this method, electronic components are continuously mounted on a tape wound around a reel, and the electronic components are taken out one by one from the tape fed from the reel by an automatic assembly machine and mounted on a printed circuit board or the like.

In the above method, in order to know the remaining amount of electronic components remaining on the tape, conventionally, the thickness t of the tape 2 wound around the reel 1 is measured as shown in FIG.
Alternatively, as described in Japanese Utility Model Laid-Open No. 2-138169, a mark for recognizing the remaining amount is provided on the tape in the vicinity of the electronic component for each constant number of the electronic components mounted on the tape.

[0004]

However, according to the method shown in FIG. 5, since the tape 2 wound around the reel 1 includes an empty portion on which no electronic component is mounted, the thickness t is reduced. It is not possible to know the remaining amount of parts only by measuring. Therefore, there is a problem that it is not possible to know when the tape is out of parts and a new reel is replaced after the assembling machine is stopped, resulting in a long stop time.

Further, in the proposal described in the above publication, the remaining amount of the component can be recognized, but the type of the component cannot be discriminated. Therefore, there is a possibility that the wrong type of reel is mounted on the assembly machine and different types of electronic components are mounted on the printed circuit board. Also, this proposal did not take into consideration the issue of an alarm to the operator when the remaining amount of parts falls below a certain amount.

The present invention has been made in view of such a situation, and detects the type and remaining amount of electronic parts mounted on a tape, displays such information, and issues an alarm to notify the end of parts. However, it is an object of the present invention to provide a component information reading device capable of preventing erroneous mounting.

[0007]

The component information reading apparatus of the present invention is a plurality of devices which are continuously mounted on a base tape 22 and are held by an upper film 23 and a lower film 24 mounted on both sides of the base tape 22. Is a component information reading device for reading information indicating the type and remaining amount of the electronic component 19, and is a take-up reel as a peeling unit that forms information on the upper film 23 and peels the upper film 23 from the base tape 22. 15 and the peeled upper film 23
It is characterized by including an OCR 15 as a reading means for reading the above information and an alarm lamp 18 as a display means for displaying the read information.

[0008]

In the component information reader having the above structure, the information formed on the upper film 23 is read after being peeled off from the base tape 22, so that the electronic component 19 mounted on the base tape 22 is not affected and the information is accurately read. Can be read. Further, when the read information is not the predetermined information, the alarm lamp 18 is turned on, so that the operator can easily know that the remaining amount of the parts has run out or erroneous mounting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the component information reading apparatus of the present invention will be described below with reference to the drawings.

1 and 2 show the configuration of an embodiment of the present invention. In FIG. 1, a component supply tape 12 is wound around a supply reel 11. As shown in FIG. 2, the tape 12 is composed of a base tape 22 having holes 21 for mounting electronic components, and an upper film 23 and a lower film 24 that cover the upper and lower surfaces of the base tape 22. The electronic components mounted in the holes 21 are the upper and lower films 23,
It is held by 24.

Guide holes 25 for feeding the tape 12 are provided on one side of the tape 12 at regular intervals. Further, on the surface of the upper film 23 formed of a transparent film, a component mark 26 indicating the component type and a remaining amount mark 27 indicating the remaining amount of components are formed at regular intervals. These marks 26 and 27 may be numbers or letters, or may be bar codes. Also marks 26, 2
The interval of 7 is determined according to the diameter of the supply reel 11 and the size of parts. For example, in the case of small parts of 0.5 × 1 mm ² , it is 1
Every 00 pieces, 2 for large parts such as ICs
Marks 26 and 27 are provided every zero.

Referring again to FIG. 1, the tape 12 wound around the supply reel 11 is pulled out by the rotation of the sprocket 13, and the upper film 23 is wound around the take-up reel 15 via the guide roller 14 and the base tape 22. Stripped from. An optical character reader (OCR) 16 as a reading means is provided on the tape running path between the guide roller 14 and the take-up reel 15, and marks 26 and 27 formed on the upper film 23 are provided.
To read.

Marks 26 and 2 read by the OCR 16
The information of No. 7 is sent to the control device 17 and compared with the component mark and the remaining amount mark stored in the control device 17 in advance. When the component mark 26 read by the OCR 16 is different from the stored component mark, the red signal of the alarm lamp 18 as a display means is turned on. Also OC
When the remaining mark 27 read by R16 is equal to or less than the stored remaining mark 27, the red signal is turned on. It should be noted that the red signal and the yellow signal may be sequentially turned on with the reference value of the remaining amount of the components being two stages, and the red signal and the yellow signal may be blinked. When the read component mark 26 matches the stored component mark and the read remaining amount mark 27 is less than or equal to the stored reference value, the green signal is lit.

The marks 26 and 27 are the upper film 23.
May be printed with ink or written by laser. The marks 26 and 27 are formed at the same time when the electronic component is mounted on the tape 12. The remaining points of the part and the mark 27 are matched exactly. After the upper film 23 is peeled off, the electronic component 19 mounted on the base tape 22 is conveyed to an automatic assembly machine (not shown).

According to this embodiment, when the wrong reel 11 is mounted on the automatic assembling machine and the tape 12 is pulled out, the operator is informed of the mistake by the red traffic light.
It is possible to prevent erroneous mounting. Similarly, when the remaining amount of the parts becomes less than or equal to a predetermined value, a warning is given to the operator by a yellow signal or a red signal, so that the availability of the parts can be announced and the operating rate of the automatic assembly machine can be improved. At this time, even if the upper film 23 is transparent, the marks 26 and 27 are read after the upper film 23 is peeled off from the base tape 22, so that the mounted electronic component 19 is not affected.

Further, at the time of parts management, as shown in FIG. 3, the parts mounted on the reel 11 can be seen by looking at the parts mark and the remaining amount mark formed on the tape outer circumference of the reel 11 stored in the reel rack 31. You can know the model and remaining amount of. As a result, the reel 11 can be used properly, and the parts can be used up effectively. Even when there is no component mark or remaining amount mark on the outer circumference of the tape, the mark can be confirmed by slightly pulling out the tape 12 as shown in FIG.
You don't have to take it out.

In the above embodiment, the OC is used as the reading means.
Although the case of using R16 has been described, the reading means is O
The information is not limited to the CR 16, but information may be magnetically recorded by using the upper film 23 as a magnetic tape and the information may be read by a magnetic character reader (MCR). Also, the display means is not limited to the alarm lamp 18, and may be, for example, a buzzer.

[0018]

As described above, according to the component information reading apparatus of the present invention, information on the model and the remaining amount of the electronic component mounted on the tape is formed on the upper film, and this information is read and displayed. By doing so, it is possible to prevent erroneous mounting of the tape and give advance notice of the parts running out, and it is possible to improve the operating rate of the automatic assembly machine and the like.
