Description

The present invention relates to an inspection device.

Conventionally, in the manufacturing process of an extruded metal profile, the extruded profile is formed by passing through a member called a die to form a long profile having the same cross-sectional shape. The cross-sectional shape of the extruded profile is determined by the shape of the die. Therefore, by changing the shape of the die, extruded shapes having various cross-sectional shapes can be produced, and the shapes can be various and can be any shape.

However, when the extruded shape material passes through the die, a streak-like defect called a die mark is formed on the surface of the extruded shape material, which may impair the appearance of the extruded shape material. As an inspection device for inspecting such a die mark, an device for inspecting the surface of the extruded profile while the extruded profile is extruded, that is, in a state where the extruded profile is laid down is known.

For example, there is a metal surface defect line inspection device that inspects the die mark of an extruded profile (see Patent Document 1). This inspection device inspects in-line while extruding the extruded profile, and applies a luminous flux to the inspection surface and detects the specularly reflected light with a sensor (imaging device).

However, in the inspection device of Patent Document 1, since the inspection is performed in-line, the extruded profile in the extruded state is inspected. That is, since the inspection device of Patent Document 1 inspects the die mark attached in the extrusion direction while the extruded profile is extruded, it can only inspect a predetermined surface of the extruded profile.

Therefore, in order to inspect a plurality of surfaces, it is conceivable to cut out a part from the extruded profile and perform the inspection. However, when a part of the extruded shape is cut out and inspected, if the extruded shape is installed in an extruded state as in the inspection device of Patent Document 1, the desired inspection surface is directed to the photographing device depending on the shape of the extruded shape. It could not be stabilized in the state. Then, it becomes difficult to inspect the desired inspection surface.

The present invention has been made in view of the above, and an object of the present invention is to stably install an extruded profile cut out in part to perform an inspection on a desired inspection surface.

In order to solve the above-mentioned problems and achieve the object, the present invention is an inspection device for inspecting the surface of an extruded profile that is extruded and molded in the extrusion direction, and has an installation surface on the upper surface and a front surface. The extruded profile is installed in the installation section with at least a part of the installation portion where the extruded profile is installed and the end surface of the extruded profile that is perpendicular to the extrusion direction installed on the installation surface. When the inspection surface, which is a surface of the extruded shape member installed in the installation portion along the extrusion direction, is photographed from a direction perpendicular to the inspection surface, the imaging device and the imaging device. A positioning member for positioning the extruded profile so that the inspection surface is installed at a predetermined position. The positioning member includes a pressing member to which the inspection surface is pressed. The pressing member is provided on the installation surface, and the lower part of the inspection surface is pressed against the pressing member .

According to the present invention, there is an effect that a partially cut out extruded shape member can be stably installed and an inspection on a desired inspection surface can be performed.

Hereinafter, embodiments of an inspection device for inspecting the inspection surface of the extruded profile will be described in detail with reference to the accompanying drawings.

First, the extruded profile will be described with reference to FIG. FIG. 1 is a diagram showing an example of an extruded profile. The extruded profile 50 is made of, for example, aluminum, resin, plastic, or the like, and is extruded in the A direction, which is the extrusion direction, and passes through a die to form a long member having various cross sections. NS. In the example shown in FIG. 1, the cross section of the extruded profile 50 has a T-shape. When such an extruded shape member 50 is molded, a die mark M (for example, a dotted line shown in FIG. 1), which is a streak-like defect parallel to the extrusion direction (A direction), may be attached to the surface thereof. The die mark M may appear on any surface of the extruded profile 50. The inspection device of the present embodiment inspects the appearance of the die mark M generated on the surface of the extruded profile.

FIG. 2 is a diagram showing an example of visual inspection of the extruded profile. The inspection device of the present embodiment performs a visual inspection on a part of the extruded profile cut out from the extruded profile formed into a long shape. As shown in FIG. 2, in the inspection of the die mark M, first, the inspection surface 50a of the extruded shape member 50 is irradiated with light from the lighting device 2, and the reflected light is photographed by the photographing device 3. .. Then, the inspection device detects the dice mark M from the captured image by image processing and inspects the image. The arrangement of the lighting device 2 and the photographing device 3 varies depending on the inspection method.

Here, in the conventional inspection device, since the extruded profile is inspected in a state where it is placed in the extruded direction, that is, in a state where the extruded profile is laid down sideways, there are the following problems.

First, the first problem will be described. FIG. 3 is a diagram showing a state in which the extruded profile is installed. FIG. 3 is a view of an extruded profile 51 installed with the inspection surface 51a facing the imaging device 3 above, as viewed from the cross-sectional direction of the extruded profile 51. Here, the cross-sectional direction of the extruded profile is a direction in which a cut surface obtained by cutting the extruded profile in a direction intersecting the extrusion direction (preferably in a direction orthogonal to each other) can be seen.

As shown in FIG. 3, the extruded profile 51 is extruded when it is intended to be installed on a flat installation surface 5a on the upper surface of the installation table 5 so that the inspection surface 51a is the upper surface facing the photographing device 3. It is difficult to stabilize depending on the shape of the shape member 51. Specifically, for example, when the extruded shape member 51 having the shape shown in FIG. 3 is installed on the flat installation surface 5a of the installation table 5, the inspection surface 51a is correctly oriented and held with respect to the photographing device 3. Can't. That is, the extruded profile 51 rotates in the direction of arrow R1 about the support portion 51b that supports the installation surface 5a, and becomes unstable.

On the other hand, for example, it is conceivable to separately use a support member for supporting the extruded shape member 51 to stabilize the extruded shape member, but the shape of the extruded shape member varies. For this reason, it is difficult to prepare a support member that can handle any shape of the extruded profile, and it is complicated and costly to prepare a different support member each time the cross-sectional shape of the extruded profile changes. Resulting in. In FIG. 3, it is assumed that the lighting device is arranged above. In the following figures, the lighting device may be omitted as appropriate.

Next, the second problem will be described. FIG. 4 is a diagram showing a state in which extruded profiles having other shapes are installed. FIG. 4 is a view of an extruded profile 52 installed with the inspection surface 52a facing the imaging device 3 above, as viewed from the cross-sectional direction of the extruded profile 52.

As shown in FIG. 4, when the extruded shape member 52 is installed on the installation surface 5a of the installation table 5, even if it can be stably installed, the imaging conditions of the imaging device 3, for example, an inspection of the subject. The surface 52a may not be placed in an appropriate orientation, and the inspection may not be performed correctly. Specifically, in the case of the shape shown in FIG. 4, the inspection surface 52a cannot be installed so as to be orthogonal to the photographing direction of the photographing apparatus 3, and the inspection surface 52a is tilted.

On the other hand, for example, it is conceivable to move and adjust the photographing device 3 and the installation table 5, but another member such as an operating member is required, which increases the cost.

Next, the third problem will be described. FIG. 5 is a diagram showing a state in which extruded profiles having other shapes are installed. FIG. 5 is a view of an extruded shape member 53 installed with the inspection surface 53a facing the photographing apparatus 3 above, as viewed from the cross-sectional direction of the extruded shape member 53.

As shown in FIG. 5, depending on the shape of the extruded profile 53, it can be stably installed, and even if the inspection surface 53a can be oriented in a predetermined direction, the imaging conditions of the imaging device 3, for example, , The distance from the inspection surface 53a to the lighting device or the photographing device 3 cannot be set to an appropriate distance, and the inspection may not be performed correctly.

For example, since the height h1 of the extruded shape member 53 shown in FIG. 5 differs depending on the shape, the distance h2 from the inspection surface 53a to the photographing apparatus 3 also differs depending on the shape of the extruded shape member 53. Therefore, if the distance from the inspection surface 53a to the lighting device or the photographing device 3 does not meet the photographing conditions, the inspection cannot be performed correctly.

On the other hand, for example, it is conceivable to adjust the position of the lighting device, the photographing device 3, or the installation table 5, but another operating member or the like is required, which increases the cost.

Next, the fourth problem will be described. FIG. 6 is a diagram showing a state in which extruded profiles having other shapes are installed. FIG. 6 is a view of an extruded profile 54 installed with the inspection surface 54a facing the imaging device 3 below, as viewed from the cross-sectional direction of the extruded profile 54.

As shown in FIG. 6, as a method of keeping the inspection surface 54a of the extruded profile 54 at a constant distance from the photographing apparatus 3, a method of installing the extruded profile 54a on the installation surface 5a with the inspection surface 54a facing downward can be considered. In FIG. 6, for example, a hole 5b for inspection is provided in a part of the installation table 5, and the inspection surface 54a is inspected through the hole 5b. By doing so, the distance and angle between the inspection surface 54a and the imaging device 3 can be kept constant.

However, depending on the shape of the extruded profile 54, the inspection surface 54a may not be correctly oriented and held toward the photographing apparatus 3. That is, in the case as shown in FIG. 6, the extruded shape member 54 rotates in the direction of arrow R2 and becomes unstable, and the inspection surface 54a cannot be held in the correct direction.

On the other hand, for example, it is conceivable to use a support member for supporting the extruded shape member 54 to stabilize the extruded shape member 54, but another operating member or the like is required, which increases the cost.

In response to each of these problems, in the present embodiment, regardless of the shape of the extruded profile, the extruded profile can be stably installed without increasing the number of members, and the inspection surface is specified for the lighting device and the photographing device. The inspection device held at the position of is described.

(First Embodiment)
In the first embodiment, an inspection device for stably installing the extruded profile on the installation table will be described. FIG. 7 is a diagram showing an inspection device according to the first embodiment. As shown in FIG. 14, the inspection device 100 of the present embodiment includes a lighting device 2, a photographing device 3, an installation table 5, and a photographing surface 9.

As shown in FIG. 7, the installation table 5 installs an extruded shape member to be inspected, and is an example of an installation unit. The installation table 5 of the present embodiment has a flat installation surface 5a on the upper surface.

The photographing surface 9 is a wall surface in the vertical direction orthogonal to the installation table 5, and an end portion thereof is connected to the installation table 5 to fix the lighting device 2 and the photographing device 3.

Here, cutting of the extruded profile will be described. FIG. 8 is an explanatory diagram relating to a method of cutting the extruded profile. FIG. 9 is an explanatory diagram regarding how to install the extruded profile on the installation table.

The shape of the extruded shape member varies. For example, when the extruded shape member 10 having the shape shown in FIG. 8 is installed with the inspection surface 10a facing up, it comes into contact with the installation surface 5a which is the upper surface of the installation table 5. Since the surface is not flat, it cannot be installed stably. Therefore, the extruded profile 10 cannot be installed and held with the inspection surface 10a facing the lighting device or the photographing device provided at a predetermined position without using a separate support member or the like.

Therefore, when the extruded profile 10 is cut in a direction (intersection direction) orthogonal to the extrusion direction (A direction), the cut surface S becomes flat. In the extruded profile 10 cut in this way, one of the two end faces located at the end in the extrusion direction is the cut surface S.

Then, as shown in FIG. 9, the inspection device 100 is in a state where the cut surface S is in contact with the flat installation surface 5a of the installation table 5, and the extruded shape member is extruded so that the extrusion direction (A direction) is in the vertical direction. 10 can be erected and installed at a predetermined position (for example, the reference m in FIG. 9). That is, the inspection device 100 can install the extruded profile 10 on the installation table 5 with the cut surface S as the bottom surface. As a result, the inspection device 100 sets the inspection surface 10a, which is a surface orthogonal to the cut surface S, at an appropriate distance to the lighting device 2 and the photographing device 3 fixed to the photographing surface 9 (see FIG. 7). It can be installed so that it faces.

Then, the extruded profile 10 is installed standing on the installation table 5 with the cut surface S as the bottom surface, irradiated with light from the lighting device 2 from a direction intersecting the extrusion direction (A direction), and photographed by the photographing device 3. As a result, the die mark M can be inspected in a stable installation state regardless of the shape of the extruded profile.

Further, since the die mark M on the surface of the extruded shape member 10 is the same at any position in the extrusion direction, the die mark M of the entire extruded shape member 10 can be obtained by simply inspecting the extruded shape member 10 at the cut out portion. You have done the inspection.

Next, the arrangement relationship of the lighting device and the photographing device with respect to the extruded profile will be described with reference to FIGS. 10 to 14. FIG. 10 is a diagram showing an example of an extruded profile. The extruded profile 11 shown in FIG. 10 has a cross-sectional shape in which convex portions 11b and 11c are provided on the inspection surface 11a side, and is extruded in the A direction in the extrusion direction to be formed.

FIG. 11 is a diagram showing the relationship between the extruded shape shown in FIG. 10 and the lighting device. FIG. 12 is a diagram showing the relationship between the extruded shape shown in FIG. 10 and the photographing apparatus. 13 and 14 are diagrams showing the relationship between the extruded shape member shown in FIG. 10, the lighting device, and the photographing device. 11 to 13 are views seen from above when the extruded profile 11 is installed upright so that the extrusion direction is in the vertical direction.

When inspecting the inspection surface 11a of the extruded profile 11 shown in FIG. 10, when light is irradiated from the lighting device 2 installed at the position shown in FIG. 11, the shaded portion K1 that is blocked by the convex portion 11b and becomes a shadow appears. It will occur. Further, when inspecting the inspection surface 11a of the extruded profile 11 shown in FIG. 10, when an image is taken from the photographing apparatus 3 installed at the position of FIG. 12, a shaded portion K2 that cannot be photographed due to being blocked by the convex portion 11c is generated. Will end up.

In this way, when a shadow that cannot be illuminated by the lighting device 2 or a portion that cannot be photographed by the photographing device 3 occurs, the inspection surface 11a cannot be photographed correctly, so that the dice mark M can be detected accurately. Can not.

Therefore, as shown in FIG. 13, in the illuminating device 2 and the photographing device 3, the optical path of the light emitted from the illuminating device 2 and the reflected light photographed by the photographing device 3 are the inspection surfaces 11a when viewed from above. It is desirable to arrange them so that they are orthogonal to each other (vertical direction).

Therefore, in the present embodiment, as shown in FIG. 14, the lighting device 2 and the photographing device 3 are planes (FIGS.) which are planes orthogonal to the inspection surface 11a and parallel to the extrusion direction (A direction). It is arranged in the plane F) shown in 14. By arranging in this way, shadows and parts that cannot be photographed are not generated, the inspection surface 11a can be photographed correctly, and the dice mark M can be accurately detected.

Returning to FIG. 14, the inspection device 100 of the present embodiment will be described together with FIG. FIG. 15 is a diagram showing a state in which the extruded profile is installed in the inspection device of the first embodiment.

The extruded profile 12 installed in the inspection device 100 has end faces 12b and 12c, which are surfaces intersecting in the extrusion direction, at both ends in the extrusion direction (A direction). One end surface 12c is a cut surface 12c obtained by cutting the extruded profile 12 in a direction orthogonal to the extrusion direction (A direction) (intersection) as described above. Further, a die mark M may be attached to the surface of the extruded profile 12 along the extrusion direction (A direction), and the surface becomes the inspection surface 12a to be inspected.

The installation table 5 is installed with the extruded profile 12 erected so that the extrusion direction (A direction) is in the vertical direction in a state where at least a part of the cut surface 12c is installed on the installation surface 5a. As shown in FIG. 15, the extruded profile 12 of the present embodiment is installed upright on the installation table 5 with the cut surface 12c as the bottom surface in contact with the installation surface 5a.

The lighting device 2 and the photographing device 3 installed on the photographing surface 9 are provided in a plane which is orthogonal to the inspection surface 12a and parallel to the extrusion direction (A direction) (see FIG. 14). .. Note that orthogonal (vertical) is an example of "intersection", and parallel is an example of "along".

The lighting device 2 irradiates the inspection surface 12a of the extruded profile 12 with light from a direction intersecting the inspection surface 12a. In the present embodiment, the lighting device 2 irradiates the inspection surface 12a, which is a vertical surface orthogonal to the installation surface 5a, with light from the horizontal direction.

The photographing device 3 photographs the inspection surface 12a of the extruded profile 12 from a direction intersecting the inspection surface 12a. In the present embodiment, the photographing device 3 photographs the inspection surface 12a, which is a vertical surface orthogonal to the installation surface 5a, from the horizontal direction.

When the cut extruded profile 12 is to be erected, it is not always necessary to install it with the cut surface 12c as the bottom surface, and the cut surface 12c may be erected so as to be the upper surface (top surface). However, since the cut surface 12c tends to be flat, it is desirable to install the cut surface 12c so as to stand downward.

As described above, when the inspection device 100 of the first embodiment inspects the inspection surface 12a of the extruded shape member 12, a part of the inspection surface 12a is cut out to stand the extruded shape member 12 with the cut surface 12c facing downward. It is possible to maintain a stable and installed state at an appropriate position with respect to the device 2 and the photographing device 3. Therefore, it is possible to accurately inspect the inspection surface 12a of the extruded profile 12.

(Second Embodiment)
In the inspection device of the first embodiment, the extruded profile is stably installed by standing the end face (cut surface) of the extruded profile in contact with the installation table. On the other hand, the inspection device of the present embodiment is further configured to hold the inspection surface for the lighting device and the photographing device at a predetermined position (predetermined angle and distance).

Here, the cutting of the extruded profile and the arrangement relationship of the lighting device and the photographing device with respect to the extruded profile are the same as those in the first embodiment (see FIGS. 8 to 14).

The pad member 4 is provided. The lighting device 2, the photographing device 3, the installation table 5, and the photographing surface 9 are the same as those in the first embodiment. 17-1 and 17-2 are views showing a state in which the extruded shape member is installed in the inspection device of the second embodiment. In the inspection device 200 shown in FIG. 17-2, for convenience of explanation, only the lighting device 2, the photographing device 3, and the pressing member 4 are displayed.

The pressing member 4 is pressed against the inspection surface 12a of the extruded profile 12 so that the inspection surface 12a is installed at a predetermined location (predetermined distance, predetermined angle) with respect to the lighting device 2 and the photographing device 3. The extruded profile 12 is positioned, and is an example of a positioning member.

The pressing member 4 of the present embodiment is formed in a rectangular parallelepiped shape, has a width of about 1/2 the width of the inspection surface 12a and a height of about 1/4 of the inspection surface 12a. The shape of the pressing member 4 is not limited to the shape as in the present embodiment, but the light from the lighting device 2 can be applied to all the width directions of the inspection surface 12a of the extruded shape member 12. The size is such that the photographing device 3 can photograph. Further, the pressing member 4 is provided so as to project from the installation surface 5a of the installation table 5 so that the lower portion of the inspection surface 12a is pressed against the pressing member 4.

When inspecting the inspection surface 12a of the extruded shape member 12, the extruded shape member 12 is installed on the installation surface 5a of the installation table 5 as shown in FIG. 17-1. Then, as shown in FIGS. 17-1 and 17-2, when the extruded profile 12 is pressed in the direction of arrow B, a part of the lower portion of the inspection surface 12a is pressed against the pressing member 4. Become.

As a result, the inspection device 200 can easily install the inspection surface 12a at an appropriate distance (for example, the distance L shown in FIG. 16) and an angle with respect to the lighting device 2 and the photographing device 3. That is, in the inspection device 200 of the present embodiment, the pressing member 4 is provided on the installation table 5 so as to serve as a reference for positioning the extruded shape member 12 to be installed at a predetermined position.

As described above, when inspecting the inspection surface 12a of the extruded profile 12, the inspection device 200 of the second embodiment is stable because a part of the extruded profile 12 is cut out to stand the extruded profile 12 with the cut surface 12c facing downward. Can be installed. Further, the inspection device 200 is installed by pressing the inspection surface 12a of the extruded shape member 12 against the pressing member 4, so that the extruded shape member 12 is placed at a predetermined distance and a predetermined distance from the lighting device 2 and the photographing device 3. It can be positioned at an angle and can maintain the state in which the extruded profile 12 is installed at an appropriate position. Therefore, it is possible to accurately inspect the inspection surface 12a of the extruded profile 12. The inspection device 200 of the present embodiment has a configuration in which one pressing member 4 is provided, but a plurality of pressing members 4 may be provided.

(Third Embodiment)
In the inspection device of the second embodiment, one pressing member is provided on the installation surface of the installation table by being pressed against the lower part of the extruded shape member to position the extruded shape member. On the other hand, the inspection device of the present embodiment is further provided with a pressing member that is pressed against the lower portion and the upper portion of the extruded profile to position the extruded profile.

Here, the cutting of the extruded profile and the arrangement relationship of the lighting device and the photographing device with respect to the extruded profile are the same as those in the first embodiment (see FIGS. 8 to 14).

FIG. 18 is a diagram showing an inspection device according to a third embodiment. As shown in FIG. 18, the inspection device 300 of the present embodiment has a ceiling in addition to the configuration of the inspection device 100 of the first embodiment (lighting device 2, imaging device 3, installation table 5, and imaging surface 9). A surface 8 and pressing members 4a and 4b are provided. The lighting device 2, the photographing device 3, the installation table 5, and the photographing surface 9 are the same as those in the first embodiment. FIG. 19 is a diagram showing a state in which the extruded profile is installed in the inspection device of the third embodiment.

The ceiling surface 8 is provided so as to be connected to the photographing surface 9. The ceiling surface 8 is a surface parallel to the installation surface 5a and orthogonal to the photographing surface 9.

The pressing members 4a and 4b are extruded so that the inspection surface 12a of the extruded profile 12 is pressed against the lighting device 2 and the photographing device 3 so that the inspection surface 12a can be installed at a predetermined distance and at a predetermined angle. It positions the profile 12 and is an example of a positioning member.

The pressing member 4a is provided on the installation surface 5a of the installation table 5 so that the lower portion of the inspection surface 12a is pressed, as in the pressing member 4 of the second embodiment. Further, the pressing member 4b has the same shape as the pressing member 4a, and is provided on the lower surface of the ceiling surface 8 so that the upper portion of the inspection surface 12a is pressed against the pressing member 4b. The pressing member 4a is an example of the first pressing member, and the pressing member 4b is an example of the second pressing member.

When inspecting the inspection surface 12a of the extruded shape member 12, the extruded shape member 12 is installed on the installation surface 5a of the installation table 5 as shown in FIG. Then, as shown in FIG. 19, when the extruded profile 12 is pressed in the direction of arrow B, a part of the lower part of the inspection surface 12a is pressed against the pressing member 4a, and a part of the upper part of the inspection surface 12a. Is pressed against the pressing member 4b.

As a result, the inspection device 300 can easily install the inspection surface 12a at an appropriate distance and angle with respect to the lighting device 2 and the photographing device 3. Further, in the inspection device 300, when the extruded profile 12 is pressed in the direction of arrow B, the inspection surface 12a is pressed against the upper and lower pressing members 4a and 4b, so that the extruded profile 12 is extruded depending on the strength of the pressing force and the pressed position. It is possible to prevent the shape member 12 from being tilted.

Since the upper part of the cut extruded profile 12 may not reach the upper pressing member 4b, the inspection device 300 adjusts the height of the installation table 5 or the pressing members 4a and 4b. The configuration may be provided with means for adjusting the height.

As described above, when inspecting the inspection surface 12a of the extruded profile 12, the inspection device 300 of the third embodiment is stable because a part of the extruded profile 12 is cut out to stand the extruded profile 12 with the cut surface 12c facing downward. Can be installed. Further, the inspection device 300 is installed by pressing the upper and lower portions of the inspection surface 12a of the extruded profile 12 against the pressing members 4a and 4b, so that the inspection device 300 is predetermined without being tilted with respect to the lighting device 2 and the photographing device 3. It is possible to position the extruded profile 12 at a predetermined distance and a predetermined angle, and it is possible to maintain the state in which the extruded profile 12 is installed at an appropriate position. Therefore, it is possible to accurately inspect the inspection surface 12a of the extruded profile 12.

(Fourth Embodiment)
The inspection device of the second embodiment has a configuration in which a pressing member that is pressed against the lower part of the extruded profile to position the extruded profile is fixed to the installation surface of the installation table. The pressing member may be provided so as to be movable. The inspection device of the present embodiment has a configuration in which two pressing members are provided on the installation surface of the installation table.

Here, the cutting of the extruded profile and the arrangement relationship of the lighting device and the photographing device with respect to the extruded profile are the same as those in the first embodiment (see FIGS. 8 to 14).

FIG. 20 is a diagram showing an inspection device according to a fourth embodiment. FIG. 20 is a view (top view) of the state in which the extruded profile 13 is installed in the inspection device 400 as viewed from above. The inspection device 400 of the present embodiment includes pressing members 4a1 and 4a2 in addition to the configuration of the inspection device 100 of the first embodiment (lighting device 2, imaging device 3, installation table 5, and imaging surface 9). ing. Although the installation table 5 and the photographing surface 9 are omitted in FIG. 20, the lighting device 2, the photographing device 3, the setting table 5, and the photographing surface 9 are the same as those in the first embodiment.

When the width of the extruded shape member is larger than that of the pressing member, it may be unstable if the extruded shape member is supported by only one pressing member when pressed in the direction of arrow B. For example, referring to FIG. 20, as the width W of the inspection surface 13a of the extruded shape member 13 increases with respect to the pressing member 4a1, the extruded shape member 13 may become unstable. Therefore, a plurality of pressing members may be provided. The inspection device 400 of the present embodiment has a configuration in which two pressing members 4a1 and 4a2 are provided as an example, but a configuration in which three or more pressing members are provided may be provided.

The pressing members 4a1 and 4a2 are extruded so that the inspection surface 13a of the extruded profile 13 is pressed against the lighting device 2 and the photographing device 3 so that the inspection surface 13a can be installed at a predetermined distance and at a predetermined angle. It positions the profile 13 and is an example of a positioning member.

The pressing member 4a1 of the present embodiment is formed in a rectangular parallelepiped shape, has a width of about 1/8 of the width of the inspection surface 13a and a height of about 1/3 of the inspection surface 13a. The shape of the pressing member 4a1 is not limited to such a shape. The shape of the pressing member 4a2 will be described later. Further, the pressing members 4a1 and 4a2 are provided on the installation surface 5a of the installation table 5 so that the lower portion of the inspection surface 13a is pressed against the pressing members 4a1 and 4a2 of the second embodiment.

When a plurality of pressing members are provided, at least a part of the pressing members can be moved. This is to prevent the pressing member from coming into contact with the unevenness, for example, when the inspection surface of the extruded profile is not composed of only a flat surface, that is, for example, when the inspection surface is uneven. be. Further, for example, the pressing member is arranged so as to be pressed in a well-balanced manner according to the width of the extruded profile.

As shown in FIG. 20, the extruded shape member 13 installed in the inspection device 400 of the present embodiment has a shape in which a convex portion 13a1 is formed on an inspection surface 13a on the side where the pressing members 4a1 and 4a2 are pressed. It has become. Therefore, the pressing member 4a2 of the present embodiment is provided in the direction of the arrow d indicated by the broken line (direction along the inspection surface 13a) within a range in which the positional relationship between the inspection surface 13a and the lighting device 2 or the photographing device 3 does not change. It is movable.

Further, when a plurality of pressing members are provided, at least a part of the pressing members can be removed. This is because the pressing member may hinder the installation depending on the shape of the extruded profile. As shown in FIG. 20, in the inspection device 400 of the present embodiment, the pressing member 4a2 is removable.

Here, an example of the moving mechanism and the removing mechanism of the pressing member 4a2 will be described. FIG. 21 is an explanatory diagram regarding the structure of the pressing member. As shown in FIG. 21, the pressing member 4a2 is provided on the pressing surface 421 and the installation table 5 which are provided orthogonal to the installation table 5 and press the inspection surface 13a when the pressing member 4a2 is installed on the installation table 5. It is composed of a bottom surface 422 provided in parallel with the installation surface 5a and in contact with the installation surface 5a, and a protrusion 423 provided below the bottom surface 422. The push surface 421 and the bottom surface 422 are formed in a rectangular parallelepiped shape. Further, the push surface 421 has a width of about 1/8 of the width of the inspection surface 13a and a height of about 1/3 of the inspection surface 13a. Further, the installation base 5 is provided with a mounting groove 5c for mounting the pressing member on the installation surface 5a along the direction of the arrow d.

Then, the protrusion 423 provided on the bottom surface 422 of the pressing member 4a2 is inserted into the mounting groove 5c and slid in the direction of the arrow d, so that the pressing member 4a2 can move in the direction of the arrow d. Further, the pressing member 4a2 can be removed by removing the protrusion 423 from the mounting groove 5c. In FIG. 21, the extruded profile 13 is installed so that the inspection surface 13a is located on the focus line FL.

In this way, when a plurality of pressing members are provided, at least a part of the pressing members can be made movable or removable so that extruded shaped members of various shapes can be stably pressed. can.

As described above, when inspecting the inspection surface 13a of the extruded shape member 13, the inspection device 400 of the fourth embodiment is stable because the extruded shape member 13 is made to stand by cutting out a part of the extruded shape member 13 with the cut surface 13c facing downward. Can be installed. Further, by pressing the lower portion of the inspection surface 13a of the extruded shape member 13 against the pressing members 4a1 and 4a2, the extruded profile 13 can be positioned at a predetermined distance and a predetermined angle with respect to the lighting device 2 and the photographing device 3, and at an appropriate position. The state in which the extruded profile 13 is installed can be maintained. Further, since the pressing members 4a1 and 4a2 are movable or removable, positioning can be performed on the extruded profile 13 having various shapes. Therefore, it is possible to accurately inspect the inspection surface 13a of the extruded shape member 13.

(Fifth Embodiment)
The inspection device of the second embodiment has a configuration in which a pressing member is provided which is pressed against the inspection surface of the extruded profile to position the extruded profile. On the other hand, the inspection device of the present embodiment is further provided with another pressing member that presses the extruded shape member from a direction different from that of the pressing member.

Here, the cutting of the extruded profile and the arrangement relationship of the lighting device and the photographing device with respect to the extruded profile are the same as those in the first embodiment (see FIGS. 8 to 14).

FIG. 22 is a diagram showing an inspection device according to a fifth embodiment. As shown in FIG. 22, the inspection device 500 of the present embodiment is pushed in addition to the configuration of the inspection device 100 of the first embodiment (lighting device 2, imaging device 3, installation table 5, and imaging surface 9). A contact member 4 and a side surface pressing member 6 are provided. The lighting device 2, the photographing device 3, the installation table 5, and the photographing surface 9 are the same as those in the first embodiment, and the pressing member 4 is the same as in the second embodiment.

Here, the extruded shape material to be inspected by the inspection device 500 of the present embodiment will be described. FIG. 23 is a diagram showing an extruded profile to be inspected by the inspection device of the fifth embodiment. FIG. 23 is a diagram in which the extruded shape member 14 that has been extruded and passed through the die is cut at a certain position to form a cut surface S. At this time, even if the extruded profile 14 is intended to be cut in a direction orthogonal to the extrusion direction, the cut surface S may be slightly tilted as shown in FIG. 23.

Even in this state, the extruded profile 14 can be erected with the cut surface S facing down (as the bottom surface), but when the inspection device 500 is inspected in this state, the image taken by the photographing device 3 is taken. The dice mark M having this slight inclination is reflected in the image. Then, when inspecting the dice mark M from the image, processing such as correcting the inclination is required. Therefore, the inspection device 500 of the present embodiment is provided with a side pressing member 6 that presses the side surface of the extruded profile 14 when the extruded profile 14 is installed, and is configured to correct the inclination of the extruded profile 14. ..

The side pressing member 6 positions the extruded profile 14 by pressing the extruded profile 14 from a direction different from that of the pressing member 4, and is an example of the positioning member. In the present embodiment, the side surface pressing member 6 is pressed against the side surface T1 of the extruded profile 14 which is a surface intersecting the inspection surface 14a of the extruded profile 14 and the cut surface S (end surface).

The side surface T1 of the extruded shape member 14 is a surface orthogonal to the inspection surface 14a and is a side surface adjacent to the inspection surface 14a. Therefore, the side pressing member 6 is provided on the installation table 5 so that a surface orthogonal to the pressing member 4 and orthogonal to the installation table 5 is formed. The side pressing member 6 of the present embodiment is formed in a rectangular parallelepiped shape, and has a width larger than the width of the side surface T1 of the extruded profile 14 and a height larger than the height of the side surface T1. The side pressing member 6 is not limited to such a shape, but needs to have a size capable of correcting the inclination of the extruded shape member 14. Further, the side pressing member 6 is provided on the installation surface 5a of the installation base 5, and the entire side surface T1 is pressed against the side surface T1.

FIG. 24 is a diagram showing a state in which the extruded profile is installed in the inspection device of the fifth embodiment. In FIG. 24, for the sake of explanation, the pressing member 4, the side pressing member 6, and the extruded profile 14 are represented.

When inspecting the inspection surface 14a of the extruded shape member 14, as shown in FIG. 24, the extruded shape member 14 is pressed in the direction of arrow B, and the inspection surface 14a of the extruded shape member 14 is pressed against the pressing member 4. .. Then, the extruded shape member 14 is pressed in the direction of arrow C, and the side surface T1 of the extruded shape member 14 is pressed against the side surface pressing member 6.

Since the side pressing member 6 has a surface orthogonal to the installation table 5, the dice mark M is also pressed against the installation table 5 by pressing the side surface T1 of the extruded profile 14 against the side pressing member 6. Orthogonal. Therefore, since the dice marks M in the captured image are also aligned in the direction orthogonal to the installation table 5, the inclination correction process as described above becomes unnecessary.

Here, as shown in FIG. 23, when the extruded shape member 14 is tilted when the cut surface S is placed face down, that is, when the side surface T1 and the cut surface S are not orthogonal to each other, the extruded shape member 14 has the side surface T1 on the side surface. When pressed against the pressing member 6, a gap g is formed as shown in FIG. 24. Then, when the pressed state of the extruded shape member 14 is released, the gap g disappears, and the cut surface S returns to the state of contacting the installation surface 5a of the installation table 5, that is, the state of the extruded shape member 14 being tilted. However, when the extruded profile 14 is inspected by the inspection device 400 of the present embodiment, it is desirable that the extruded profile 14 is held in a pressed state. In the present embodiment, the pressed state may be held by the pressing force from the user, or for example, a support member for supporting the extruded shape member 14 may be provided to hold the pressed state.

As described above, when inspecting the inspection surface 14a of the extruded profile 14, the inspection device 500 of the fifth embodiment cuts out a part of the extruded profile 14 to stand the extruded profile 14 with the cut surface S facing downward, and presses the member. Since the extruded profile 14 is pressed against the 4 and the side pressing member 6, it can be stably installed. Further, the inspection device 500 is installed by pressing the extruded profile 14 against the pressing member 4 and the side pressing member 6, so that the extruded profile 14 is placed at a predetermined distance from the lighting device 2 and the photographing device 3. It is possible to position the extruded shape member 14 at a predetermined angle and maintain the state in which the extruded shape member 14 is installed at an appropriate position. Further, the inclination of the extruded profile 14 can be corrected by pressing the extruded profile member 6 against the side pressing member 6. Therefore, it is possible to accurately inspect the inspection surface 14a of the extruded profile 14.

(Sixth Embodiment)
The inspection device of the fifth embodiment has a configuration in which a pressing member and a side pressing member that are pressed against the inspection surface and the side surface of the extruded shape member to position the extruded shape member are provided. On the other hand, in the inspection device of the present embodiment, the extruded shape member is sandwiched and held from the side surface by providing two side pressing members.

Here, the cutting of the extruded profile and the arrangement relationship of the lighting device and the photographing device with respect to the extruded profile are the same as those in the first embodiment (see FIGS. 8 to 14).

FIG. 25 is a diagram showing an inspection device according to a sixth embodiment. As shown in FIG. 25, the inspection device 600 of the present embodiment is pushed in addition to the configuration of the inspection device 100 of the first embodiment (lighting device 2, imaging device 3, installation table 5, and imaging surface 9). The contact member 4 and the side surface pressing members 6a and 6b are provided. The lighting device 2, the photographing device 3, the installation table 5, and the photographing surface 9 are the same as those in the first embodiment, and the pressing member 4 is the same as in the second embodiment. Further, the inspection target by the inspection device 600 of the present embodiment is the extruded profile 14 similar to that of the fifth embodiment.

The side pressing members 6a and 6b position the extruded profile 14 by pressing the extruded profile 14 from a direction different from that of the pressing member 4, and are an example of the positioning member. In the present embodiment, the side pressing members 6a and 6b are surfaces T1 and T2 of the extruded profile 14 (see FIG. 23), which are surfaces that intersect the inspection surface 14a of the extruded profile 14 and the cut surface S (end surface). ) Are pressed against each other.

The side surface T1 of the extruded profile 14 is the same as in the fifth embodiment. Further, the side surface T2 of the extruded profile 14 is a side surface opposite to the side surface T1 and is a surface orthogonal to the inspection surface 14a and a side surface adjacent to the inspection surface 14a, similarly to the side surface T1. .. Therefore, the side pressing members 6a and 6b are provided on the installation table 5 so as to form a surface orthogonal to the pressing member 4 and orthogonal to the installation table 5. The side pressing members 6a and 6b of the present embodiment are formed in a rectangular parallelepiped shape like the side pressing members 6 of the fifth embodiment, and have a width larger than the width of the side surfaces T1 and T2 of the extruded profile 14. Therefore, the height is larger than the heights of the side surfaces T1 and T2. The side pressing members 6a and 6b are not limited to such a shape, but need to have a size capable of correcting the inclination of the extruded shape member 14. Further, the side pressing members 6a and 6b are provided on the installation surface 5a of the installation base 5, and are installed so that the entire side surfaces T1 and T2 are pressed against each other.

Further, the side pressing members 6a and 6b are sandwiched by pressing the side surfaces T1 and T2 of the extruded shape member 14, respectively, to hold the extruded shape member 14 at a predetermined position. Therefore, for example, the side pressing member 6a is fixed, and the side pressing member 6b is aligned with the width of the extruded profile 14 (the length from the side surfaces T1 to T2) along the installation surface 5a of the installation table 5. It is movable.

Here, the side pressing member 6b and the installation base 5 have the same moving mechanism as in FIG. 21, for example. That is, a protrusion is provided on the bottom surface side of the side pressing member 6b, and a mounting groove is provided on the installation surface 5a of the installation base 5. Then, the protrusion of the side pressing member 6b is inserted into the mounting groove of the installation base 5 and moves, so that the side pressing member 6b can move. Further, the side pressing member 6b may be provided with a stopper member such as a lever, and the stopper member may be configured to hold a state at a predetermined position. Further, the moving mechanism may be configured by using a rack and pinion in which the side pressing members 6a and 6b are connected to the end of the rack. Both the side pressing members 6a and 6b may be configured to be movable along the installation surface 5a of the installation table 5.

FIG. 26 is a diagram showing a state in which the extruded profile is installed in the inspection device of the sixth embodiment. In FIG. 26, for the sake of explanation, the pressing member 4, the side pressing members 6a and 6b, and the extruded profile 14 are represented.

When inspecting the inspection surface 14a of the extruded shape member 14, as shown in FIG. 26, the extruded shape member 14 is pressed in the direction of arrow B, and the inspection surface 14a of the extruded shape member 14 is pressed against the pressing member 4. .. Then, the side pressing member 6b is pressed in the arrow C direction until it comes into contact with the side surface T2, and then the side pressing member 6b and the extruded profile 14 are pressed in the arrow C direction in an integrated state. , The side surface T1 of the extruded shape member 14 is pressed against the side surface pressing member 6a. As a result, the extruded profile 14 is sandwiched and held by the side pressing members 6a and 6b.

Since the side pressing members 6a and 6b are planes orthogonal to the installation table 5, the die mark M is also installed by pressing the extruded profile 14 against the side pressing members 6a and 6b and sandwiching the members. Orthogonal to the table 5. Therefore, since the dice marks M in the captured image are aligned in the direction orthogonal to the installation table 5, the inclination correction process and the like are not required as in the fifth embodiment.

FIG. 27 is a diagram showing a state in which the extruded shape member is installed in another example of the inspection device of the sixth embodiment. Further, as shown in FIG. 27, the movable side pressing member 6b may be a side pressing member 6b ′ having a shape bent at a right angle. As a result, the extruded profile 14 is tilted by countering the pressing force from the side surface T2 with the force that the surface of the side pressing member 6b'that comes into contact with the installation surface 5a presses against the installation surface 5a (FIG. It is possible to avoid returning to (see 23). That is, the side pressing member 6b'can hold the extruded profile 14 at a predetermined position by sandwiching the extruded profile 14 together with the side pressing member 6a.

As described above, when inspecting the inspection surface 14a of the extruded profile 14, the inspection device 600 of the sixth embodiment cuts out a part of the extruded profile 14 to stand the extruded profile 14 with the cut surface S facing downward, and presses the member. Since the extruded profile 14 is pressed against the 4 and the side pressing members 6a and 6b, the extruded profile 14 can be stably installed. Further, the inspection device 600 sets the extruded profile 14 against the lighting device 2 and the photographing device 3 by pressing the extruded profile 14 against the pressing member 4 and the side pressing members 6a and 6b. It is possible to position the extruded shape member 14 at a distance and a predetermined angle, and to maintain the state in which the extruded shape member 14 is installed at an appropriate position. Further, the inclination of the extruded profile 14 can be corrected by pressing against the side pressing members 6a and 6b. Further, by sandwiching the extruded shape member 14 between the side pressing members 6a and 6b, the extruded shape member 14 can be held at a predetermined position. Therefore, it is possible to accurately inspect the inspection surface 14a of the extruded profile 14.
