An inspection management system having a plurality of processes and managing final inspection performed to inspect a completed product and one or more intermediate inspections performed to inspect an intermediate product manufactured in the processes earlier than a final process includes: an inspection content data acquisition unit that acquires inspection content data including an inspection standard for each inspection item of the product; an inspection content setting unit that sets inspection content based on the inspection content data acquired by the inspection content data acquisition unit; a simulation unit that simulates inspection in accordance with assumed inspection content; an inspection standard calculation unit that calculates an inspection standard more appropriate than a current inspection standard based on the simulation; and an output unit that outputs base information indicating that at least the inspection standard calculated by the inspection standard calculation unit is more appropriate than the current inspection standard.

Inspection management system, inspection management apparatuses, and inspection management method

An inspection management system that manages inspection of an inspection apparatus in a production line including a manufacturing apparatus of a product and the inspection apparatus includes: an acquisition unit configured to acquire inspection content data including an inspection standard for each component; an inspection content setting unit configured to set inspection content; a setting-related information acquisition unit configured to acquire setting-related information including at least a time at which new inspection content is set when the inspection content setting unit sets the new inspection content; a storage unit configured to retain the setting-related information in association with a history of the setting of the inspection content; a setting-related information reading unit configured to read the setting-related information retained in the storage unit; and an output unit configured to be able to output the setting-related information.

An inspection apparatus includes an imaging unit that captures an image of a board having a land on which a solder piece has been printed, an image of the board having a component mounted on the solder piece, or an image of the board having the component soldered to the land, a land determination unit that determines a position of an element on the board other than the land from the image of the board captured by the imaging unit, and determines a position of the land in the image based on the determined position of the element, and an inspection unit that inspects the solder piece or component on the land using the position of the land determined by the land determination unit as a reference.

Inspection apparatus and quality control system for surface mounting line

An optical data code reader includes an illuminator device for illuminating an optical data code to be read out, an image-taking device for taking an image of this optical data code, a readout device for decoding the optical data code by processing image data generated by the image-taking device and an adjustment device for carrying out an adjustment process. The adjustment device adjusts an illumination condition of the illuminator device and/or an image-taking condition for the image-taking device such that the image data become suitable for being read out. The adjustment device serves to set areas on image data outputted by the image-taking device, to extract a variation amplitude of brightness in each of the areas and to carry out the adjustment process by using the image data of at least one of the areas in which the extracted variation amplitude is greater than a specified threshold value.

Device for reading optical data code

A device for reading out an optical code includes a camera, an image memory for storing images taken by this camera, and an image processor for decoding an optical code contained in an image taken by the camera. A plurality of images are obtained continuously with the camera under specified image-taking conditions in response to a specified image-taking command, and the obtained images are stored on the image memory. The images stored in the image memory are sequentially selected one at a time in a specified order, and the image processor makes an attempt to decode an optical code contained in the selected image. Results of decoding are outputted if the attempt to decode any of the stored images is successful. The interval at which the images are taken is changed according to the number of images successfully decoded taken continuously in the past.

Method of and device for reading optical code

Two-dimensional code reader

A two-dimensional code reader repeats a cycle of ordinary code-reading processes such as taking an image of an optical data code, extracting a two-dimensional code from the image and decoding optical data of the two-dimensional code in the image. A specified evaluation value for the optical data code is obtained from the results of processes carried out prior to the decoding step and stored if the decoding is done successfully. Data which show the changes in the evaluation value with time are displayed. The evaluation value may be compared with a specified warning level and a warning output is made, depending on the result of the comparison.
