BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to automatic mounting of electronic components.

0002

2. Description of the Related Art In recent years, the assembly of electronic devices has changed from manual assembly to automatic assembly by machines. FIG. 4 is a perspective view showing the structure of a conventional carrier tape for supplying electronic components. As shown in the figure, the tape that arranges and holds the electronic components is wrapped around a reel, and a label indicating the product name of the electronic components is attached to the reel, and a mark indicating the approximate number of components is attached to the window. provided. When mounting electronic components in such a state on a mounting machine and performing mounting work, it is important to be able to predict component supply shortages accurately or to switch components in a short time. There is.

[Problems to be Solved by the Invention] With such conventional carrier tapes, there is a problem in that it is easy to make mistakes because the names and remaining amounts of parts are confirmed with the human eye. In particular, since the remaining amount is estimated by a mark provided on the window of the reel, it cannot be said to be accurate. Also, I sometimes overlooked the fact that the remaining amount was zero.

[0004] The present invention solves the above-mentioned problems, and aims to provide a carrier tape for electronic components that allows a computer to automatically and accurately determine component names and remaining amounts without relying on human judgment. .

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention assigns numbers corresponding to the arrangement order of electronic components arranged at predetermined intervals to corresponding parts positions at predetermined number intervals. The carrier tape is provided with a tape displayed with a barcode, and a barcode indicating the product name of the electronic component and a barcode indicating the number of the electronic component at the origin of the array are written on a reel around which the tape is wound.

[0006]

According to the present invention, the number indicated by the bar code on the tape corresponds to the order in which the electronic components are arranged, and the bar code on the label on the reel corresponds to the number of the origin of the arrangement of the parts on the tape. In addition, by indicating the number and product name with a barcode, it can be read by a machine, and the remaining amount is calculated from the array number and the origin number, and the product name is confirmed.

[0007]

EXAMPLE 1 A carrier tape according to an example of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a tape 1 that holds electronic components in an array is wound around a reel 2, and on the side of the reel, the product name and total number of electronic components are indicated in letters and numbers. , a label 3 is attached with a barcode 6 indicating the product name and a barcode 7 indicating the number of the part at the origin of the arrangement. Further, the tape 1 is provided with a bar code 4 indicating a number corresponding to the arrangement order of the electronic components arranged at predetermined intervals. The numerical value of this number does not indicate the remaining amount itself, but corresponds to a serial number corresponding to the electronic component.

FIG. 2 shows details of the number display on the tape. As shown in the figure, electronic components are arranged on a tape 1 at predetermined intervals, and a bar code 4 indicating an arrangement number is provided for every two electronic components. In the example shown in the figure, since the electronic components are small, every other number is replaced with a barcode.
It is written as 2.m and is added so as to increase toward the end of winding the tape.

FIG. 3 shows details of the display of the label 3. As shown in the figure, the product name is shown in letters and the total number of employees is shown in numbers, as well as a bar code 6 indicating the product name and an origin code 7. This origin code org is a code indicating the start of tape winding, that is, the number of the last electronic component to be mounted. Therefore, point A (number m) on any tape
The remaining amount in is m-org. Of course, org may be zero.

[0011] On the other hand, a mounting apparatus for mounting the tape and performing mounting work is provided with means for reading the barcode on the label and the barcode on the tape. The mounting machine uses a reading means to determine the product name from the label on the reel, and can also determine the remaining amount from the origin code and number code.

As described above, according to the tape carrier of the embodiment of the present invention, the numbers corresponding to the electronic components arranged at predetermined intervals are written on the tape using bar codes, and the reel around which the tape is wound is marked with the numbers corresponding to the electronic components arranged at predetermined intervals. By indicating the barcode indicating the name of the electronic component and the number of the electronic component at the start end of the tape, the above codes can be read by the reader of the mounting machine to determine the name of the electronic component and the remaining amount. It can be grasped automatically and accurately.

In the embodiment, the numbers are assigned in ascending order from the beginning of winding of the tape, but it goes without saying that they may be assigned in descending order to correspond to the number of tapes attached. In this case, it goes without saying that the origin number written on the label may be the number of the end of the tape winding.

Further, in the embodiment, the bar code is written on the side line portion of the tape, but it may be written between the electronic components.

[0015] Furthermore, the number of mounted devices can be known from the number at the time of the start of mounting and the current number.

[0016]

Effects of the Invention As is clear from the above embodiments, the present invention provides a tape with barcodes displaying numbers corresponding to the arrangement order of electronic components arranged at predetermined intervals. , by providing a carrier tape with a bar code indicating the product name of the electronic component and a label indicating the bar code indicating the number of the electronic component at the origin of the array on a reel around which the tape is wound, the mounting machine can be mounted. By reading the code using the code reading means, it is possible to automatically and accurately know the product name, remaining amount, number of mounted electronic components, etc. of the electronic component.
