Embodiment Construction

[0062] Hereinafter, embodiments of the present invention will be described with reference to the drawings. At the same time, the components, arrangement, etc. described below are not limited to those mentioned in the present invention, and various changes can be made within the scope of the gist of the present invention.

[0063] The two-dimensional barcode related to this embodiment is formed by arranging light and dark cells in a matrix according to dot marks. The form of the two-dimensional barcode can adopt data matrix, QR code (quick response matrix code) and the like.

[0064] The dot marking method refers to a method of creating a two-dimensional barcode by forming a plurality of dots on a marking object. In this specification, it includes two types: a laser marking method and a printing method.

[0065] As shown in FIGS. 3 and 4 , examples of two-dimensional barcodes are shown. A two-dimensional barcode is a combination of white spaces and black bars arranged in a ma...

Abstract

PROBLEM TO BE SOLVED: To provide a traceability management method and a management device which can easily access the manufacture history information of individual part constituting a product, and which can effectively avoid producing defective products by reflecting it to the production process of products. ŽSOLUTION: This method of managing manufacture history information of an electric apparatus 70 is composed of singular or a plurality of parts 72. It is provided with a manufacture history information acquiring process that acquires the manufacture history information about the parts 72, a two-dimensional coding process that two-dimensionally codes data, including identification number that identifies the manufacture history information about the parts 72 or manufacture history information, a parameter setting process that sets the size of the two-dimensionally coded two-dimensional code 1 according to the parts 72, a laser marking process that directly laser-marks the two-dimensional code 1 of the set size to the parts 72 by a laser marker 40, and a manufacturing process that produces an electrical apparatus 70, by installing the parts 72 in which the two-dimensional code 1 is laser-marked.

Description

technical field [0001] The invention relates to a method and a device for forming a two-dimensional barcode formed by laser marking. In particular, it relates to a method and apparatus for forming a two-dimensional barcode suitable for tracking management of all products including electronic / electrical equipment, machinery, vehicles, and housing components made by assembling a plurality of components for a single product. Background technique [0002] In product quality management, production process information such as quality data of parts and raw materials used in the production process, or adjustment data when adjusting production conditions such as temperature, time, and size, adjustment data when adjusting products, and inspection data when inspecting products are passed through the product The manufacturer's database is managed. [0003] In order to obtain the production process information of each product recorded in this database, a product number is attached to th...
