Description

  The present invention relates to a skin pinhole inspection apparatus for inspecting whether or not there is a pinhole in the skin of a vehicle interior product.

  In general, pinholes may occur in resin molded products due to molding defects. When inspecting for the presence or absence of such pinholes, a light source is arranged on one side of the molded product and a light receiving means is arranged on the other side. Then, whether or not the molded product has a pinhole is detected depending on whether or not the light receiving means receives the inspection light emitted from the light source (see Patent Document 1).

  Such an inspection method is also employed for inspecting the skin of a vehicle interior product having a core material and a skin covering the core material. Usually, when inspecting the epidermis, the epidermis is held by hand, and a place where there is a risk of forming a pinhole is held over the light source. And the presence or absence of a pinhole is confirmed by visually observing whether there is light passing through the epidermis.

JP2002-310924

  When a pinhole is inspected with the skin in hand, the pinhole may be crushed unless the skin is properly held to prevent wrinkles. When the pinhole is crushed, since the inspection hole does not pass through the skin, the skin having the pinhole passes the inspection as a normal product. As a result, the inspection accuracy is lowered. In addition, there are many places on the epidermis where there is a risk of pinholes being formed. In such a case, inspection must be performed while changing the epidermis many times, There was a problem that the labor efficiency was reduced and the work efficiency was lowered.

In order to solve such a problem, the inventor of the present application initially considered mounting the epidermis on the mounting member when inspecting the pinhole. However, in order to do so, a dedicated mounting member has to be produced for each vehicle interior to be inspected, and there is a problem that the mounting member requires a large amount of cost.

  In order to solve the above problem, the present invention provides an inspection apparatus for inspecting whether or not there is a pinhole in the skin of a vehicle interior product having a core material and a skin covering the surface of the core material. And a mounting member on which the epidermis is mounted on the surface portion, and a light source disposed on the back side of the mounting member, and the cutout portion is provided as a mounting member at a location corresponding to the inspection target site of the epidermis. The formed core material is used, and the light source is disposed so as to face the notch.

  According to the present invention having the above-described characteristic configuration, when the skin is inspected, it is only necessary to attach the skin to the mounting member, and it is not necessary to change the skin. Therefore, the labor of the worker can be reduced and the work efficiency can be improved. Further, since the mounting member is constituted by the core material to which the skin to be inspected is attached, the skin can be held substantially in the original shape. Therefore, the pinhole is not crushed and the pinhole can be reliably detected. In addition, since the mounting member is produced using the core material, the cost required for the mounting member can be reduced, and the manufacturing cost of the inspection apparatus can be reduced at a low cost.

The best mode for carrying out the present invention will be described below with reference to the drawings.
1 to 3 show an instrument panel (vehicle interior) 1 having a skin whose presence or absence of a pinhole is inspected by the skin inspection device according to the present invention. Of course, the skin pinhole inspection apparatus according to the present invention can also be used for inspection of the skin of vehicle interior parts other than the instrument panel 1 such as a door trim. The instrument panel 1 has a front plate portion 1a having a substantially “U” shape in the horizontal direction, and side plate portions 1b and 1b formed on both left and right sides of the front plate portion 1a. The side plate portion 1b extends along the front plate portion 1a and protrudes from the front plate portion 1a to the back side of the instrument panel 1.

  The instrument panel 1 includes a core material 2 and a skin 3. The core material 2 is formed by molding a resin, and has sufficient rigidity to maintain the entire instrument panel 1 in a certain shape. The core member 2 constitutes the back side portion of the instrument panel 1. Therefore, the core material 2 has a front plate portion 2a and side plate portions 2b, 2b corresponding to the front plate portion 1a and the side plate portions 1b, 1b of the instrument panel 1. On the other hand, the skin 3 is formed by a vacuum forming method or the like, and has appropriate flexibility. The skin 3 is fixed to the surface of the core material 2 and constitutes a surface side portion of the instrument panel 1. Therefore, the skin 3 also has a front plate portion 3a and side plate portions 3b, 3b corresponding to the front plate portion 1a and the side plate portions 1b, 1b of the instrument panel 1.

  The skin 3 is relatively thin. For this reason, there is a risk that pinholes are formed in the skin 3 when molding the resin. The risk of forming pinholes is not uniform over the entire skin 3, and the risk is high at each intersection of the front plate portion 3a and the side plate portions 2b, 2b. In particular, the risk is high at the central portion (the portion surrounded by the Y and Z circles) of the intersection between the front plate portion 3a and the side plate portion 2b. In other parts, there is almost no risk of forming pinholes. Accordingly, when inspecting the skin 3 for the presence or absence of pinholes, it is sufficient to inspect the intersection between the front plate portion 3a and the side plate portion 3b.

  Next, an inspection apparatus for inspecting whether or not there is a pinhole in the skin 3 of the instrument panel 1 will be described. As shown in FIGS. The mounting member 20 and the light source 30 are provided.

  The mounting member 20 has the surface 3 attached to the surface 21 side portion (surface portion), and is mounted on a base (not shown). The mounting member 20 is configured by cutting out a part of the core material 2 of the instrument panel 1. A part of the core material 2 to be cut out is a part corresponding to a part where there is a risk that a pinhole of the skin 3 is formed. As described above, there is a risk that a pinhole is formed in the skin 3 at the intersection of the front plate portion 3a and the side plate portion 3b. Therefore, in this embodiment, both left and right end portions of the core member 2 are cut away (in FIGS. 4 and 5, the left end portion notched is indicated by an imaginary line. The right end portion is omitted). Thus, the mounting portion 20 is configured.

  In addition, in the skin 3, when the location where there is a risk of forming a pinhole is a location other than the intersection between the front plate portion 3a and the side plate portion 3b, the portion corresponding to the location of the core material 2 is notched. It is. Further, in the case where the risk of forming a pinhole is not at the entire intersection of the front plate portion 3a and the side plate portion 3b but at the center portion, as shown in FIG. You may form the notch 22 only in the center part of the cross | intersection part of the front board part 2a of the material 2 and the side board part 2b.

  The light source 30 is for irradiating the inspection light to the part corresponding to the notched portion of the core member 2 in the skin 3 attached to the attachment member 20. Therefore, the light source 30 is disposed on the back side of the mounting member 20 so as to face the notch portion of the core member 2. Therefore, the light sources 30 are respectively disposed on both end sides of the mounting member 20. Of course, when the notched portion is present at other than the both end portions of the core member 2, another light source 30 is disposed so as to face the notched portion. Although an incandescent lamp is used as the light source 30 in this embodiment, other light emitting means may be used.

  When inspecting whether or not there is a pinhole in the epidermis 3 using the inspection apparatus 10 having the above configuration, the epidermis 3 is first attached to the surface 21 side portion of the attachment member 20. When the attachment of the skin 3 to the attachment member 20 is completed, the light source 30 is turned on. Then, when the skin 3 has a pinhole, the inspection light emitted from the light source 30 passes through the pinhole and leaks to the surface side of the mounting member 20. By visually observing the leaked light, it can be confirmed that the skin 3 has a pinhole. When the skin 3 has no pinhole, the inspection light from the light source is blocked by the skin 3, so that the inspection light is not visually observed. Thereby, it can be confirmed that there is no pinhole.

  According to the pinhole inspection apparatus, since the skin 3 is mounted on the mounting member 20, it is not necessary for the operator to hold the skin 3 by hand when inspecting the pinhole. Moreover, there is no need to change the epidermis 3. Therefore, worker fatigue can be reduced and the inspection efficiency can be improved. Moreover, since the mounting member 20 is configured using the core material 2, the manufacturing cost of the inspection apparatus can be reduced at a low cost. Moreover, the mounting member 20 can hold the epidermis 3 as it is without any wrinkling. Therefore, a situation where the pinhole is crushed can be prevented. Therefore, inspection accuracy can be improved.

In addition, this invention is not limited to said embodiment, In the range which does not deviate from the summary, it can change suitably.
For example, in the above-described embodiment, the skin 3 of an instrument panel (interior product) in which the skin 3 is directly provided on the core material 2 is to be inspected, but the interior product in which the skin is provided on the core material via a foam layer. It can also be applied to the epidermis. In that case, what is necessary is just to use what cut | disconnected each part of the core material and foam layer corresponding to the location where the pinhole of an outer skin is formed while adhering a foam layer to a core material.
In the above embodiment, the inspection light emitted from the light source is visually confirmed. However, the light receiving means is arranged on the surface 21 side of the mounting member 20 so as to face the light source 30. A warning means that issues a warning when the light receiving means detects the inspection light leaking from the pinhole may be provided to check whether or not there is a pinhole based on the presence or absence of a warning by the warning means.
