Problems solved by technology

Therefore, it is practically impossible for a user who is not familiar with the expert knowledge of a computer to easily write an appearance inspection program suitable for the appearance inspection of the product to be inspected
[0007] In addition, when the product to be inspected is changed, the image data processed with this appearance inspection program have nothing in common
If the inspection parameters used in this visual inspection procedure are not based on actual image data of the product to be inspected, the reliability and accuracy of the visual inspection will be reduced
Also, if the inspection result obtained through the image processing step in the appearance inspection is not confirmed in advance, the result of the appearance inspection becomes unreliable

Embodiment Construction

[0042] A first embodiment of the present invention will now be described. The appearance inspection program writing device according to the present invention supports the user of the appearance inspection device to easily write the appearance inspection program used in the appearance inspection device and appropriately inspect products conveyed on the production line.

[0043] In this embodiment, the program writing device can be independent of the appearance inspection device. This program writing device may also be included in the visual inspection device. In the former case, the program for writing the appearance inspection program can be installed in a well-known device such as a personal computer or a dedicated device described below. In the latter case, the processing unit of the appearance inspection device takes the role of the program writing device.

[0044] FIG. 1 illustrates a block diagram of a program writing device 20 in the first embodiment. FIG. 2 visually ...

Abstract

A programming apparatus supports a user to program a visual inspection program used in a visual inspection apparatus. A plurality of standard inspection flows corresponding to kinds of products to be inspected, a plurality of image processing algorithms and a plurality of inspection parameters used in the visual inspection of the product are previously memorized. The user prepares a plurality of image data of defective units and non-defective units of the product which he wishes to inspect, and programs a provisional visual inspection program configured by the standard inspection flow corresponding to the kind of the product which is selected by the user, the image processing algorithms and the inspection parameters selected by following a guidance of the standard inspection flow. The provisional visual inspection program is evaluated by using the sample image data whether it is proper or improper for inspecting the product.

Description

technical field [0001] The present invention relates to an apparatus for writing an appearance inspection program used in an appearance inspection apparatus for inspecting the appearance of products conveyed on a production line. Background technique [0002] Generally, appearance inspection equipment is used to inspect the appearance of products in the production process. In commonly used appearance inspection equipment, the visual image of the appearance of the product is obtained by a camera through an image acquisition device such as a CCD (charge-coupled device), and the image data corresponding to the visual image of the product output from the camera can be predetermined as follows: Appearance inspection program to determine whether the appearance of the product has reached the predetermined quality. [0003] Prior to the current appearance inspection of products, adjusting the appearance inspection program and parameters in such a manner tha...
