CONSTITUTION:First, information is stored into an information processor 9 for managing serial numbers on layout positions of individual parts 4 for mounting electronic component-packaged substrates of a group 3 thereof beforehand. Then, after or when a worker mounts an electronic component-packaged substrate 1 for an operation test at the mounting section 4, a bar code 2 on the substrate 1 is read by a serial number reading means freely at any time. At this point, light emitted from a projector photoelectric sensor 7 mounted on a bar code reader 6 is detected with a receiver photoelectric sensor 5 mounted on the mounting part 4 and the resulting switching information is stored into a register device 8 by a position detecting means reading serial numbers as layout position information. An information processor performs a corresponding operation of the information by a serial number position information corresponding means to accomplish a management of the serial numbers.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a serial number management system that can be used when performing an operation test with a mass batch testing device for various electronic component mounting boards of information processing equipment. .

BACKGROUND ART In general, when performing an operation test on various electronic component mounted boards of information processing equipment using a bulk test equipment, and especially when it is necessary to obtain operation test results, it is common practice to Location information is necessary and important, and serial number management is performed at this time. At this time, serial number management is simplified by adding means for reading serial numbers to electronic component mounting boards.

A conventional serial number management method when a bar code is provided on a conventional electronic component mounting board will be described below.

FIG. 3 shows a conventional serial number management method. In FIG. 3, reference numeral 17 indicates an electronic component mounting board to be subjected to an operation test, 12 indicates serial number reading means on the electronic component mounting board, 13 indicates a serial number reading device for reading the serial number, and 14 indicates a serial number based on the read information. An information processing device that performs number management; 16 is an electronic component mounting board mounting section group having a plurality of electronic component mounting board mounting sections; 16 is each electronic component mounting board mounting section of the electronic component mounting board mounting section group 15;

With the above configuration, a conventional serial number management system will be described below with reference to the block diagram of FIG. 4.

First, the information processing device 15 that performs serial number management stores in advance the arrangement position information of the electronic component mounting board mounting section 17 of the electronic component mounting board mounting section group 16. next,
An operator places the electronic component mounting board 18 in each electronic component mounting board mounting part 17 of the electronic component mounting board mounting part group 16 according to the previously stored arrangement position information of the electronic component mounting board mounting part 17. Serial number reading means 22 on board 18 (in this example, barcode reading device 14
), the information processing device 15 performs serial number management based on the serial number position information correspondence means 19. Alternatively, after all the electronic component mounting boards 18 have been mounted, the operator uses the serial number reading means 22 on the electronic component mounting boards 18 to read the arrangement position information in order according to the arrangement position information of the electronic component mounting board mounting section 17. The serial information processing device 15 performs serial number management by associating serial numbers with each other based on the serial number position information matching means 19.

Problems to be Solved by the Invention However, in the above-mentioned conventional configuration, the operator reads the serial number reading means 22 in the correct order according to the arrangement position information of the electronic component mounting board mounting section 17 stored in the information processing device 16 in advance. Therefore, if the reading order is incorrect, the correspondence between the placement position information of the electronic component mounting board mounting section 17 and the serial number indicated by the serial number reading means 22 will be broken, resulting in a failure in serial number management. If the electronic component mounting board 18 is replaced after reading all the information, transfer means 2 such as reconsidering the correspondence between the placement position information of the replaced electronic component mounting board 18 and the serial number.
If step 1 is carried out and the serial number position information corresponding processing 20 is not provided in the case of exceptions, the accuracy of the serial number of the electronic component mounting board 18 and the placement position information of the electronic component mounting board 18, which is important when performing bulk bulk testing, will be reduced. This method has the disadvantage that accurate correspondence is not guaranteed.

The present invention solves the above-mentioned conventional problems, and uses a simple configuration and method when reading the correspondence relationship between the arrangement position information of the electronic component mounting board mounting section 17 and the serial number indicated by the serial number reading means 22. The correspondence is automatically made, and there is no need for the means 20 for dealing with serial number position information in the case of an exception when replacing the electronic component mounting board 18 that may occur after the completion of the matching, and the arrangement of the electronic component mounting board mounting portion 17 is eliminated. 6 with an excellent serial number management system that automatically associates location information with the serial number indicated by the serial number reading means 22 and guarantees accurate association.
Ru.

Means for Solving the Problem In order to solve this problem, the serial number management system of the present invention includes a group of electronic component mounting board mounting parts equipped with a photoelectric sensor emitter or a light receiver, and a serial number management system on the electronic component mounting board. The serial number reading device is equipped with a photoelectric sensor receiver or a light emitter, and the serial number is read by a reaction operation of the photoelectric sensor of the electronic component mounting board mounting section group and the photoelectric sensor of the serial number reading device. The present invention is configured to include a method for automatically determining specific positional information in the group of electronic component mounting board mounting sections at the time of reading.

Function: With this configuration, when an operator reads the serial number on the electronic component mounting board, the photoelectric sensor attached to both the electronic component mounting board mounting section group and the serial number reading device automatically reads the serial number. Since the serial number is associated with the placement position information of each electronic component mounting board mounting part in the electronic component mounting board mounting part group, there is no need to read the serial number in a predetermined order, and the electronic component mounting board mounting part Even if it is necessary to replace an electronic component mounting board mounted at an arbitrary position in a group, it is easy to associate the placement device information with the serial number, which reduces the workload and furthermore, is important for mass batch testing equipment.
