Abstract

PURPOSE:To enable a detailed recording every printed circuit board of a goods lot No. by applying a label expressing a type and the lot No. in a bar code to the goods (box) and applying the label expressing the serial No. in the bar code to the printed circuit board and reading them so as to process in a computer at the time of exchanging the parts or mounting them. CONSTITUTION:When the parts of a mounting machine 1 run short, the exchange of the parts is executed in a home position 3. In this case a bar code label 5 is read with a bar code reader 8 and the time what kind of lot of what kind of parts of what kind of type is exchanged is inputted in a host computer 7. If the parts run short, the information about it is transmitted from the computer 2 to the host computer 7. Meanwhile the label 9 expressing the serial No. In the bar code is applied to the printed circuit board 10, and it is read with the bar code reader (non-touch type) 11 after mounting so as to input in the computer 7 concerning which printed circuit board is mounted and also when it is mounted. Thus, the information of the parts are easily and finely managed without paper.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for recording component lots () & in mounting electronic components onto a printed circuit board.

(Prior Art) Conventionally, in order to create a record of the lot numbers of components mounted on printed circuit boards, barcode labels have been read with a barcode reader and inputted into a computer, as a matter of course. However, the recorded items were only the mounting die, for example, and no detailed data was recorded for each printed circuit board.

(Problem to be solved by the invention) PL (Product I, 1abil) in the United States
ity) When strict quality control is required as in the problem, the rod number of the component is determined for each printed circuit board. It becomes necessary to record.

In order to cope with this, the parts rod No. The problem that the present invention seeks to solve is to create detailed records for each printed circuit board.

(Means for solving problems) FIG. 1 shows a specific example of the present invention, where 1 is the main body of the mounting machine.

2 controls the mounter with a dedicated CPU for the mounter ・Written around the mounter 1, ■, O1...O is the component/, 2
,3. ...This is a rack that hangs 10 parts boxes, and when a part runs out during work, parts are replaced at fixed position 3. 5 is a barcode label on which the part type and number (number) are printed and is pasted on the parts box 6 (see FIG. 2) and stored in the parts shelf 4.

When the mounting machine 1 runs out of parts, the parts are replaced at a fixed position 3. At this time, a bar code reader (pencil type) 8 reads the bar food label 5. This inputs into the host computer 7 which model, which part, and which lot was replaced and when.

(The internal clock of the computer is used for the time.) When a part runs out, the information is transmitted from the computer 2 to the host computer γ.

On the other hand, a label 9 on which a serial number is barcoded is attached to the printed circuit board 10 (see FIG. 3), and is read by a barcode reader (non-contact type) 11 after mounting. This inputs into the computer 7 which printed circuit board was mounted and when.

(Function) Data related to parts and data related to printed circuit boards are organized in a chronological order in a computer.

(Example) The technical means are the same as the specific example (Fig. 1) described in the section of means for solving problems.

However, as a result of the technical means of the present invention, it will be described as part of the embodiment that when two types of data input to a computer are arranged in chronological order, the following registration table (table/) is obtained.

According to table/, for example, parts/lots) 3'l! It can be seen that ; is used for 00100 to 01002 of the printed circuit board.

Conversely, if we focus on the printed circuit board DO100, we can also see which lot l& is used for parts/~Otsu0.

(Effect of the invention) As explained above, the model number and lot number are indicated on the parts (boxes).
Attach a barcode label with each serial number to the printed circuit board and read it when replacing or mounting.
By processing with a computer, the rod number of the component is determined for each printed circuit board. This allows easy and detailed management without paper.

Claims (1)

[Claims] 1. When mounting electronic components on a printed circuit board, the model and rod number of the component are determined in advance. A label attached to the parts box with a bar code, and a serial number in advance. The label attached to the printed circuit board is read as a barcode using a dedicated barcode reader before and after the mounting process.
In addition to these two readings, the mounting date and time are also input into the computer. Recording system. 2. The barcode label on the parts box is read when replacing the parts box, and the barcode label on each printed circuit board is read with each barcode reader after mounting, and the year, month, day, and time are read using the computer's internal clock. Component rod No. 1 according to claim 1, characterized in that: Recording system.
