Embodiment Construction

[0040] Hereinafter, modes for implementing the present invention will be described in detail based on examples with reference to the drawings. However, the scope of the present invention is not limited to the dimensions, materials, shapes, relative arrangements, and the like of the components described in this embodiment unless otherwise specified.

[0041]

[0042] figure 1 It is a diagram schematically showing a configuration example of production equipment and a quality control system on a surface mount production line for printed circuit boards. Surface Mount Technology (SMT) refers to the technology of soldering electronic components on the surface of printed circuit boards. The surface mount production line mainly consists of three processes: solder printing, component placement, and reflow soldering (solder deposition).

[0043] Such as figure 1As shown, in the surface mount production line, as production equipment, a solder printing device X1, a placement machine X...

Abstract

Provided is a quality management device, comprising: a facility information acquisition means for acquiring data of a facility state value which is observed when processing a product with a manufacturing facility and which represents a state of the manufacturing facility; and a product information acquisition unit which acquires data of a product state value which is measured from the product which is processed by the manufacturing facility and which represents a state of the product. When a given product is assessed to be defective, the quality management device assesses, by a comparison with a good quality distribution of the product state value, whether the product state value of the defective product is an anomalous value, and assesses, by a comparison with a good quality distribution of the facility state value, whether the facility state value when the defective product is processed is an anomalous value. If it is assessed that either the product state value or the facility state value relating to the defective product is an anomalous value, the quality management device determines that a fault has occurred with the manufacturing facility.

Description

technical field [0001] The present invention relates to a technique for managing the quality of a production line. Background technique [0002] In production lines that are becoming increasingly automated and labor-saving, inspection devices are installed in the middle or final process of the production line to automatically detect defective products or classify defective products. In addition, an attempt is also made to infer the main cause of failure from the inspection results of the inspection equipment, and to make use of it in quality control and maintenance of production equipment. [0003] In such a quality management system, if the judgment criteria for inspection and the management criteria for quality are not properly set, the efficiency of the production line may decrease. The reason for this is that, for example, if the standard is too loose, it will lead to an increase in defective products, the burden of visual inspection, and the cost of discarding non-conf...
