Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an object inspection device and an object inspection computer program for inspecting an object for defects, appearance, characteristics, etc., and more particularly to a technique for converting inspection results into an electronic file.

[0002]

2. Description of the Related Art As objects for inspecting for defects, appearance, features, etc., liquid crystal elements, liquid crystal displays, optical parts, glass, electronic parts such as silicon wafers, hulls and car bodies, etc.
There are a wide variety of things such as the walls of buildings. As a conventional object inspection method, when visually inspecting a defect or appearance on an object, an operator observes the position, type, shape, number, characteristics, etc. of the defect on the inspection result entry sheet. The method of filling in the results is common.

However, the inspection (observation) as described above
In the method of writing the result on the form, the position of the defect on the form is an approximate position, so it cannot be accurately identified during re-inspection, especially when there are multiple defects. There is a problem that it is not possible to identify even one defect. Further, when the inspection is performed and then the classification is performed based on the inspection result, the defect position, the number, the distribution, and the like are standards of the classification, and this work becomes very complicated. Also, when the operator makes a recording while observing, since the line of sight is reciprocated between the object to be inspected and the entry form,
Accuracy and work efficiency decrease. Further, when the number of objects to be inspected is large, the number of filling sheets becomes large, so that it takes time to create a report such as a daily report and there is a problem that accuracy is insufficient.

Therefore, as a method for solving the above problems, in recent years, there has been a method in which an object to be inspected is imaged by an electronic image pickup means such as a CCD camera, a solid-state image pickup device, an FA camera, etc., and the inspection result is digitized into an image file. It is taken. As another conventional example, for example, Japanese Patent Publication No. 7-18
In Japanese Patent Laid-Open No. 807 and Japanese Patent Laid-Open No. 10-325780,
As a method of digitizing the inspection result of the display element of the liquid crystal display, the GUI of the display screen of the liquid crystal display is used.
A method of writing the inspection result as a screen and digitizing it has been proposed.

[0005]

However, in the method of photographing the object to be inspected by the electronic image pickup means and digitizing the inspection result into an image file, the imaged screen is further GU.
Since it is necessary to display it as the I screen and write the inspection result, there is a problem that it takes time and the file capacity becomes large. In the method disclosed in the above publication,
There is a problem that the object to be inspected is limited to a display element such as a liquid crystal display.

In view of the above-mentioned problems of the conventional example, the present invention is an object inspection apparatus and an object inspection which can digitize an inspection result without imaging the object to be inspected and without limiting the object to be inspected. A computer program for use is provided.

[0007]

In order to achieve the above object, the present invention provides a defect position designating unit for designating a defect position on an object to be inspected by an inspector, and the defect position designating unit. The defect position detecting means for detecting the defect position designated by is provided, and the defect position is displayed on an input screen for inputting the inspection result of the object to be inspected and converted into an electronic file.

That is, according to the present invention, the defect position designation means for designating the defect position on the object to be inspected by the inspector and the defect position detection for detecting the defect position designated by the defect position designation means. Means, a display means for displaying an input screen for inputting an inspection result of the object to be inspected, and a defect position detected by the defect position detecting means on the input screen of the display means. And a control means for converting the defect position displayed in to an electronic file,
An object inspection apparatus having the same is provided.

According to the present invention, the step of displaying an input screen for inputting the inspection result of the object to be inspected on the display means, and the defect position on the object to be inspected by the inspector to be visually inspected are designated. For object inspection, which has a step of displaying on the input screen of the display means the defect position specified by the position detection means and detected by the position detection means, and a step of converting the defect position displayed on the input screen into an electronic file. A computer program is provided.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. 1 is a block diagram showing an embodiment of an object inspection apparatus according to the present invention, FIG. 2 is an explanatory view showing an object to be inspected, and FIGS. 3 to 6 are explanations showing an inspection result input screen of the object inspection apparatus of FIG. It is a figure.

In FIG. 1, an object inspection device 10 includes a stylus 11a, a position detection device 11b, and a personal computer 12.
And monitor 13 (and mouse, keyboard, etc.). The stylus 11a uses infrared rays, ultrasonic waves,
When a worker specifies a defect position of the object to be inspected by the stylus 11a, the position detector 11b detects a coordinate position designated by the stylus 11a. Then, the detected position is taken into the personal computer 12, and the personal computer 12 executes the object inspection computer program.

The object to be inspected in this embodiment is, for example,
The projection device 14 has a liquid crystal element, and the liquid crystal element in the projection device 14 projects the inspection image generated by the image generation device 15 onto the projection screen 16. Therefore, the object inspection computer program of the personal computer 12 is configured to inspect the liquid crystal element for defects such as black dots, black lines, black unevenness, white dots, white lines, and white unevenness. Then, when the operator visually inspects the inspection image projected on the projection screen 16 and indicates the defect position with the stylus 11a, the position is captured by the personal computer 12 via the position detection device 11b.

FIG. 2 shows an inspection image 20 projected by the projection device 14 which is an object to be inspected. This inspection video 2
0 is a white screen for detecting which of the many liquid crystal elements formed in a matrix are black dots, black lines, and black unevenness, and the defective liquid crystal element cannot display white. For example, it becomes a black dot (defect 21 in the figure).

FIG. 3 shows a defect 2 of the inspection image 20 shown in FIG.
1 shows the state in which the operator has instructed with the stylus 11a. Then, the position is the position detection device 1
When loaded into the personal computer 12 via 1b, the personal computer 12 displays the GUI screen 30 of the monitor 13 as shown in FIG.
A + mark 31 is displayed at a position corresponding to the upper detection position, and a guide display 32 is displayed near the mark 31. The defect type described above is displayed on the guide display 32 shown in FIG. 4, and the guide display 32 can be moved to another position by dragging the mouse or can be switched between display / non-display by right-clicking.

In the guide display 32 shown in FIG. 4, when the operator clicks on the "black dot" in the guide display 32 with the mouse, the position of the defect 21 and its defect type are determined, and then the guide display 32 as shown in FIG. Instead of "black dot"
A guide display 33 for inputting the number and size of the is displayed.
In this display state, when the operator moves the mouse and clicks, for example, the number = 1 and the size = 2, the number and size of the black dots are determined. Then, as shown in FIG. Is displayed at that position, and a defect information display 35 of "black dots (1,2)" indicating the number of units = 1 and the size = 2 is displayed in the vicinity thereof. As a result, the positions of the black dots 34 (coordinates on the screen), the number of black dots,
The input of the inspection result of the size is completed, and the process moves to the input of another defect position. These pieces of information are generated and stored as an electronic file using characters and numbers such as text data as code information.

According to the above embodiment, since the inspection result is converted into an electronic file, paper and writing tools are not required, and the totaling work can be automated and reused. Furthermore, the operator can input the defect position only by aligning the stylus 11a with the defect or feature of the object to be inspected. After inputting the defect position, the monitor 13
Since it is possible to proceed with the inspection while looking at the GUI screen, the inspection can be performed without taking a look from the inspection screen, and the inspection work efficiency is improved. Further, when the size of the object to be inspected is different, it can be easily dealt with by simply changing the size of the input screen of the monitor 13. Therefore, a large-scale change or adjustment of the device is unnecessary.

Further, the work can be completed in a shorter time than the method in which the image of the inspected object itself is imaged by the electronic image pickup means and the imaged screen is displayed to write the inspection result. Since the file is not an image file, the file size can be reduced. Also,
The type of object to be inspected is not limited to the display element,
With the stylus 11a and the position detection device 11b, it is possible to inspect all objects for which defect positions can be input. Furthermore, the object to be inspected is not limited to two dimensions, and three-dimensional objects can be inspected.

Further, the GUI screen may be displayed on the wall surface by a projector instead of being displayed on the monitor 13 of the personal computer 12. In addition, G
