Appearance check device and appearance check method

Abstract

The invention provides an appearance check device and an appearance check method, and check precision and quality can be ensured always by the invention. A shooting apparatus is used to shoot a clamp for correction; based on a measurement value for correction drawn from shot image information, in a correction structure in which a correction handling executor executes data for correction for storing, before displaying production start screen, check screen before production is displayed according to the correction message for correction order. Therefore, execution miss of correction caused by human fault like storage error made by the operators can be reliably prevented, and check precision of the appearance check device can be ensured, and check quality can be ensured.

Description

technical field [0001] The present invention relates to an appearance inspection device and an appearance inspection method. The appearance inspection device is arranged on an electronic component mounting line and performs a predetermined inspection based on image information obtained by photographing an inspection object. Background technique [0002] The component mounting line that mounts components on the substrate to manufacture the mounted substrate is composed of a plurality of devices such as a solder printing device, a component mounting device, and a reflow soldering device. When the device is heated, the solder is melted and solidified, and solder joint is performed. In this part mounting process, visual inspection is performed at each step in order to confirm whether the solder printing state, the part mounting state, and the final part joining state are correct or not. In this visual inspection, based on the image information obtained by photographing the boar...

AI Technical Summary

Problems solved by technology

However, since the calibration work of the inspection function requires man-hours such as installing a prepared calibration jig for each measurement item and photographing it, in normal production activities, delicate work is performed frequently Correction jobs become unrealistic

Therefore, the inspection accuracy of the visual inspection device may not always be guaranteed, and if an inspection error is found in a subsequent process to judge a non-conforming product as a good product, it is necessary to investigate the cause and trace it back to which process, which is unclear. actual situation of judgment

In this way, in the prior art, it is difficult to always ensure the inspection accuracy of the visual inspection device, and there is a problem that the inspection quality cannot be guaranteed.
