Abstract

PURPOSE:To provide a soldering inspecting apparatus which can easily detect whether the soldering state of a part mounted to a substrate is good or bad. CONSTITUTION:This soldering inspecting apparatus consists mainly of a controller box 15, an X-Y stage 16 and an operation box 17 which are electrically connected each other. When a step switch 27 of the operation box 17 is depressed, an X-Y axis controlling part 20 drives an X-axis shaft 23 and a Y-axis shaft 25 in the corresponding axial directions. Accordingly, a CCD camera 22 is moved over a printed circuit board 26. A CCD camera controller 19 takes images from the CCD camera 22, and accordingly parts on the printed circuit board 26 are displayed on a color monitor 18. When a window switch 28 of the operation box 17 is manipulated, a detection reference image is displayed on the color monitor 18.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a soldering inspection device for inspecting a soldering state of a component mounted on a board.

[0002]

2. Description of the Related Art In recent years, a soldering inspection apparatus for displaying a component mounted on a substrate on a monitor screen or the like using a CCD camera or the like has become mainstream. Hereinafter, a conventional soldering inspection apparatus will be described with reference to FIGS. 3 and 4.

As shown in FIG. 3, the soldering inspection apparatus mainly comprises a controller box 1, an XY stage 2 and an operation box 3, which are electrically connected to each other. The controller box 1 is a color monitor 4, C
It is composed of a CD camera controller 5 and an XY axis control unit 6, the XY stage 2 is composed of a CCD camera 7, an X axis 8, a printed circuit board pedestal 9, a Y axis 10 and a printed circuit board 11, and the operation box 3 is , A step switch 12 is provided. A parts inspection pass / fail judgment standard document (not shown) is provided near the XY stage 2.

The operation of the above structure will be described. By pressing the step switch 12 of the operation box 3,
The XY axis control unit 6 drives the X axis 8 and the Y axis 10 in the axial direction, the CCD camera 7 moves onto the printed circuit board 11, the CCD camera controller 5 captures an image from the CCD camera 7, and the printed circuit board. The component 14 mounted on the component 11 is displayed on the color monitor 4. After that, the quality of the soldering state of the component 14 to the printed circuit board 11 is compared with the criteria of the soldering state of the component 14 described in the quality check document of the component inspection and the component 14 displayed on the color monitor 4. To judge.

[0005]

However, in the conventional soldering inspection apparatus, when the soldering state of the component 14 is inspected, the inspection is performed while referring to the component inspection pass / fail judgment standard document, so that the comparison observation can be performed at the same time. No, the above standard 13
Since the criterion in (1) is drawn by a picture, it has a drawback that it is easy to erroneously judge whether the above condition is good or bad.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a soldering inspection apparatus which can easily judge the quality of the soldering state of a component mounted on a board even at a delicate inspection point. To do.

[0007]

In order to achieve the above-mentioned object, the soldering inspection apparatus of the present invention is a soldering inspection apparatus of the present invention, in which a component soldered to a substrate is displayed on a display screen. The quality criterion of No. 1 was set so that it could be displayed on the display screen.

[0008]

With this configuration, the components soldered to the substrate and the quality determination criteria of the soldering state of the components are displayed simultaneously and on the same display screen.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

The soldering inspection apparatus mainly comprises a controller box 15, an XY stage 16 and an operation box 1.
7, which are electrically connected to each other.

The controller box 15 comprises a color monitor 18, a CCD camera controller 19, an XY axis control section 20, and a monitor screen control section 21 having a window function, and the XY stage 16 is a CCD camera 2.
2, an X-axis 23, a printed circuit board pedestal 24, a Y-axis 25, and a printed circuit board 26. The operation box 17 has a step switch 27 and a window switch 28. As shown in FIG. 2, a monitor screen 29 and a judgment reference window 30 are arranged on the color monitor 18. The monitor screen 29 shows what the CCD camera 22 shows, and the judgment reference window 30 shows the soldering state of the parts. It has a function of displaying each of the determination reference images 31 which are the determination reference.

To explain the operation in the above configuration, by pressing the step switch 27 of the operation box 17, the XY axis control section 20 drives the X axis 23 and the Y axis 25 in the axial direction, and the CCD camera 22 operates. Moved onto the printed circuit board 26, the CCD camera controller 19 moved to CC
An image is taken from the D camera 22, and the component 32 mounted on the printed circuit board 26 is displayed on the monitor screen 29.

Further, when the window switch 28 of the operation box 17 is pushed in this state, the judgment reference window 30
The judgment reference image 31 is displayed on the screen, so that both the component 32 soldered to the printed circuit board 26 and the judgment reference image 31 are displayed on the monitor screen 29.

As described above, according to the embodiment of the present invention, both the component 32 soldered to the printed circuit board 26 and the judgment reference image 31 can be displayed on the monitor screen 29, so that they can be easily compared. You can do this,
The quality of the soldered state of the inspection component can be easily determined.

[0015]

As is apparent from the above description, the soldering inspection apparatus of the present invention shows the soldering state of the component while the component to be inspected for the soldering state is displayed on the display screen. Since it is possible to display the image that is the quality criterion on this display screen, it is possible to display both the parts and the image on the same display screen, which makes it easy to compare the parts and the images. As a result, the quality of the soldering state of the component can be easily determined.
