Description

  The present invention relates to a dimensional inspection instrument used for inspection of dimensions of a sheet-like member.

  A limit gauge is known as an inspection device for checking the dimensions of a product. As such a limit gauge, for example, there is a so-called pinch gauge for inspecting the outer dimension of the shaft as shown in Patent Document 1. This pinch gauge consists of a gauge with the maximum allowable dimension (so-called street side) and a gauge with the minimum allowable dimension (so-called stop side), and it is determined that the member passing through the street side satisfies the maximum allowable dimension. The member that stops at is determined to satisfy the minimum allowable dimension. Such a limit gauge is often used at the time of dimensional inspection in various manufacturing processes because it can easily determine whether or not the dimensions of the product are within the allowable dimension range.

  However, for example, a thin and soft sheet-like member such as a foil member used for an electrode of a power storage device is likely to be warped or lifted during inspection with a limit gauge, and cannot be easily and accurately inspected.

  Accordingly, an object of the present invention is to provide a dimensional inspection instrument capable of accurately and easily confirming dimensions even for a sheet-like member.

  A dimension inspection instrument for a sheet-like member according to one aspect of the present invention is a dimension inspection instrument for inspecting the dimension of an object to be inspected that is a sheet-like member, and is between a first clamping member and a first clamping member.

The position of the 2-gauge reference surface 53b and the position of the first reference surface 25b of the positioning unit 20 coincide with each other in the X-axis direction (see FIG. 4B).

  Next, a method for inspecting the dimension of the inspection object 70 by the dimension inspection instrument 1 of the present embodiment will be described in detail mainly with reference to FIGS. FIG. 3 is an explanatory view showing an inspection method with the dimension inspection instrument 1. 4 is a cross-sectional view taken along line IVA-IVA shown in FIG. 1 and a cross-sectional view taken along line IVB-IVB. FIG. 5 is a diagram for explaining an inspection method for the maximum allowable dimension and an inspection method for the minimum allowable dimension for the inspected object 70, respectively.

  First, a method for inspecting whether or not the inspection object 70 is formed to the maximum allowable dimension will be described. First, the inspection object 70 is set on the dimension inspection instrument 1. As shown in FIG. 3, the positioning unit 20 is placed on the placement plate 10. Specifically, the positioning unit 20 is mounted on the mounting plate 10 so that the steps 15a and 15b of the mounting plate 10 and the first reference surfaces 25a and 25b of the positioning unit 20 are in contact with each other.

  Next, the inspection object 70 is placed on the placement plate 10. Specifically, the inspection object 70 is placed on the mounting plate 10 so that the two sides 75a and 75b of the outer edge portion of the inspection object 70 and the first reference surfaces 25a and 25b of the positioning unit 20 are in contact with each other. Placed on.

  Next, the clamping plate 30 is placed on the inspection object 70, and the inspection object 70 is clamped between the mounting plate 10. Specifically, the sandwiching plate 30 is placed on the inspection object 70 such that the two sides 35a and 35b of the outer edge portion of the sandwiching plate 30 and the first reference surfaces 25a and 25b of the positioning unit 20 are in contact with each other. Put.

  Next, the maximum allowable dimension inspection gauge portion 40 is disposed on the sandwiching plate 30. Specifically, the maximum permissible dimension inspection gage part so that the two sides 47a and 47b of the outer edge part of the maximum permissible dimension inspection gage part 40 and the second reference surfaces 27a and 27b of the positioning part 20 are in contact with each other. 40 is arranged on the clamping plate 30.

  By passing through the process demonstrated above, the setting of the to-be-inspected object 70 with respect to the dimension inspection instrument 1 is completed. The maximum allowable dimension inspection gauge portion 40 is aligned by bringing one side 47a of the outer edge portion of the maximum allowable dimension inspection gauge portion 40 into contact with the second reference surface 27a of the positioning portion 20. At this time, the position of the first gauge reference surface 43a in the maximum allowable dimension inspection gauge unit 40 and the position of the first reference surface 25a of the positioning unit 20 match in plan view as viewed from the Z-axis direction. Since the inspected object 70 is aligned with one side 75a of the inspected object 70 in contact with the first reference surface 25a of the positioning unit 20, the maximum allowable dimension inspection gage portion in plan view as viewed from the Z-axis direction. The position of the first gauge reference surface 43a at 40 coincides with the position of one side 75a of the inspection object 70.

  Further, the maximum allowable dimension inspection gauge portion 40 is aligned by bringing one side 47 b of the maximum allowable dimension inspection gauge portion 40 into contact with the second reference surface 27 b of the positioning portion 20. At this time, the position of the first gauge reference surface 43b in the maximum allowable dimension inspection gauge unit 40 and the position of the first reference surface 25b of the positioning unit 20 coincide with each other in plan view as viewed from the Z-axis direction. Since the inspected object 70 is aligned by bringing one side 75b of the inspected object 70 into contact with the first reference surface 25b of the positioning unit 20, the gauge portion for the maximum allowable dimension inspection in a plan view viewed from the Z-axis direction. The position of the first gauge reference surface 43b at 40 coincides with the position of one side 75b of the inspection object 70.

  Thus, in the dimension inspection instrument 1 in a state where the maximum allowable dimension inspection gauge portion 40 is positioned with respect to the inspection object 70, visual inspection is performed from the following viewpoints. That is, as shown in FIG. 5A, whether or not there is a continuous gap G between the outer edge portion 70a of the inspection object 70 and the edge portion 41a of the penetrating portion 41 of the maximum allowable dimension inspection gauge portion 40. To check. The continuous gap G refers to the outer edge portion 70a and the edge portion 41a that continuously extend along the outer edge portion 70a of the object 70 to be inspected and the edge portion 41a of the penetrating portion 41 in the maximum allowable dimension inspection gauge portion 40. It is called a gap between.

  Here, when there is a continuous gap between the edge portion 41a of the penetrating portion 41 of the maximum allowable dimension inspection gauge portion 40, the inspected object 70 is formed in a dimension shape that is equal to or less than the maximum allowable dimension. Judgment (pass inspection). On the other hand, when there is no gap between the edge part 41a of the penetration part 41 of the maximum allowable dimension inspection gauge part 40, it is determined that the inspection object 70 is formed in a dimension shape larger than the maximum allowable dimension. (Inspection failed).

  Next, a method for inspecting whether or not the inspection object 70 is formed to the minimum allowable dimension will be described. A difference from the method of inspecting whether or not the inspection object 70 is formed to the maximum allowable dimension is that the minimum allowable dimension inspection gauge part 50 is used instead of the maximum allowable dimension inspection gauge part 40. That is, the minimum allowable dimension inspection gauge unit 50 is sandwiched so that the two sides 57a and 57b of the outer edge portion of the minimum allowable dimension inspection gauge unit 50 and the second reference surfaces 27a and 27b of the positioning unit 20 are in contact with each other. Place on the plate 30. Also in this case, the position of one side 75a of the inspection object 70 is aligned with the position of the first gauge reference surface 53a of the minimum allowable dimension inspection gauge portion 50 in the Y-axis direction.

  Thus, in the dimension inspection instrument 1 in a state where the minimum allowable dimension inspection gauge portion 50 is positioned with respect to the inspection object 70, visual inspection is performed from the following viewpoints. That is, as shown in FIG. 5B, whether or not there is a continuous gap G between the outer edge portion 70a of the inspection object 70 and the edge portion 51a of the penetrating portion 51 of the minimum allowable dimension inspection gauge portion 50. To check.

  Here, when there is no continuous gap between the edge portion 51a of the penetrating portion 51 of the minimum allowable dimension inspection gauge portion 50, the inspected object 70 is formed in a dimension shape that is equal to or larger than the minimum allowable dimension. Judgment (pass inspection). On the other hand, when there is a gap between the edge portion 51a of the penetrating portion 51 of the minimum allowable dimension inspection gauge portion 50, it is determined that the object to be inspected 70 is formed in a dimension shape smaller than the minimum allowable dimension. (Inspection failed).

  In the dimensional inspection instrument 1 described above, since the inspection object 70 is sandwiched between the placing plate 10 and the sandwiching plate 30, warpage and floating unique to the sheet-like member can be suppressed. Further, two sides 75a and 75b of the outer edge portion of the inspection object 70 sandwiched by the mounting plate 10 and the sandwiching plate 30 with respect to the positioning unit 20, and the maximum allowable dimension inspection gauge section 40 or the minimum allowable dimension inspection. The position of the two sides 75a and 75b of the outer edge portion of the object to be inspected 70 and the maximum allowable dimension inspection gauge by a simple operation by simply contacting the two sides 47a, 47b, 57a and 57b of the outer edge portion of the gauge portion 50 The positions of the two sides (first gauge reference surfaces 43a and 53a and second gauge reference surfaces 43b and 53b) of the through portions 41 and 51 in the portion 40 or the minimum allowable dimension inspection gauge portion 50 are viewed from the Z-axis direction. Can be matched in a plane. In the dimension inspection instrument 1 in which the inspection object 70 is set in such a state, as shown in FIGS. 5A and 5B, the outer edge portion 70a of the inspection object 70 and the maximum allowable dimension inspection gauge. The size and shape can be easily inspected simply by observing the presence or absence of the gap G between the edge portions 41a and 51a of the through portions 41 and 51 of the portion 40 or the minimum allowable dimension inspection gauge portion 50. As a result, even if it is a sheet-like member, a dimension can be confirmed correctly and easily.

  Although one embodiment has been described above, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the invention.

  The dimension inspection instrument 1 of the above embodiment has the maximum allowable dimension inspection gauge part 40 and the minimum allowable dimension inspection gauge part 50, respectively, and the inspection object is obtained by changing the gauge parts 40, 50 respectively. Although an example of inspecting whether or not 70 dimensions satisfy the maximum allowable dimension and the minimum allowable dimension has been described, the present invention is not limited to this. For example, by using the dimension inspection gauge unit 140 described below, it is possible to inspect at once whether the dimensional shape of the inspection object 170 satisfies the maximum allowable dimension and the minimum allowable dimension.

  FIG. 6 is a plan view of a dimensional inspection gauge unit included in the dimensional inspection instrument 1 according to another embodiment. As shown in FIG. 6, the dimensional inspection gauge portion 140 has a through portion 141 penetrating in the thickness direction. This dimensional inspection gauge part 140 is characterized by a planar shape as viewed from the thickness direction of the through part 141.

  That is, as shown in FIG. 7, a maximum permissible dimension inspection part 141 a that is a part that can secure a maximum permissible dimension as an internal dimension and a minimum permissible dimension as an internal dimension can be secured at a part of the edge of the penetrating part 141. A minimum allowable dimension inspection portion 141b, which is a portion, is formed. When the two sides 147a and 147b of the outer edge portions (side portions) of the dimension inspection gauge portion 140 are brought into contact with the second reference surfaces 27a and 27b of the positioning portion 20, the dimension inspection gauge portion 140 The position of the first gauge reference surface 143a that is one side coincides with the position of the first reference surface 25a of the positioning unit 20 in the Y-axis direction, and the position of the second gauge reference surface 143b that is one side of the penetrating part 141 The position of the first reference surface 25b of the positioning unit 20 matches in the X-axis direction.

  Such a dimension inspection gauge portion 140 is formed on the holding plate 30 so that the two sides 147a and 147b of the outer edge portion of the dimension inspection gauge portion 140 and the second reference surfaces 27a and 27b of the positioning portion 20 are in contact with each other. Arrangement of the inspection object 170 with respect to the dimensional inspection instrument 1 is completed.

  At this time, the dimension inspection gauge portion 140 is aligned by bringing one side 147a of the outer edge portion of the dimension inspection gauge portion 140 into contact with the second reference surface 27a of the positioning portion 20. At this time, the position of the first gauge reference surface 143a in the dimensional inspection gauge unit 140 matches the position of the first reference surface 25a of the positioning unit 20 in a plan view as viewed from the Z-axis direction. Since the inspected object 170 is aligned by bringing one side 175a of the inspected object 170 into contact with the first reference surface 25a in the positioning unit 20, the plan view viewed from the Z-axis direction is performed in the dimensional inspection gauge unit 140. The position of the first gauge reference surface 143a coincides with the position of one side 175a in the inspection object 170.

  The dimension inspection gauge unit 140 is aligned by bringing one side 147b of the dimension inspection gauge unit 140 into contact with the second reference surface 27b of the positioning unit 20. At this time, the position of the first gauge reference surface 143b in the dimensional inspection gauge unit 140 matches the position of the first reference surface 25b of the positioning unit 20 in a plan view as viewed from the Z-axis direction. The inspected object 170 is aligned by bringing one side 175b of the inspected object 170 into contact with the first reference surface 25b in the positioning unit 20, so that the inspected object 170 in the dimensional inspection gauge unit 140 is a plan view as viewed from the Z-axis direction. The position of the first gauge reference surface 143b coincides with the position of one side 175b in the inspection object 170.

  Thus, the visual inspection is performed from the following viewpoints in the dimension inspection instrument 1 in a state where the dimension inspection gauge part 140 is positioned with respect to the inspection object 170. That is, as shown in FIGS. 8A to 8C, the outer edge portion 170a of the inspection object 170 and the edge portion of the penetration portion 141 of the dimension inspection gauge portion 140 (the maximum allowable dimension inspection portion 141a and the minimum allowable dimension). The state of occurrence of a gap with the inspection unit 141b) is confirmed.

  Here, as shown in FIG. 8A, the outer edge 170a of the inspection object 170 and the edge of the penetration part 141 of the dimension inspection gauge part 140 (maximum allowable dimension inspection part 141a and minimum allowable dimension inspection part 141b). ), The object 170 to be inspected is formed in a dimensional shape that is less than or equal to the maximum allowable dimension, and is formed in a dimensional shape that is greater than or equal to the minimum allowable dimension. It is judged (passed inspection) that it is done.

  As shown in FIG. 8B, the outer edge portion 170a of the inspection object 170 and the edge portions (the maximum allowable dimension inspection portion 141a and the minimum allowable dimension inspection portion 141b) of the penetrating portion 141 of the dimension inspection gauge portion 140. When it can be confirmed that there is a gap G2 having a continuous portion therebetween, it is determined that the inspection object 170 is formed in a dimensional shape smaller than the minimum allowable dimension (inspection failure).

  As shown in FIG. 8C, the outer edge portion 170a of the inspection object 170 and the edge portions (the maximum allowable dimension inspection portion 141a and the minimum allowable dimension inspection portion 141b) of the penetrating portion 141 of the dimension inspection gauge portion 140. When a gap cannot be confirmed between them, it is determined that the inspection object 170 is formed in a dimension shape larger than the maximum allowable dimension (failed inspection).

  In this dimension inspection instrument 1, since the inspected object 170 is sandwiched between the placing plate 10 and the sandwiching plate 30, it is possible to suppress warpage and floating characteristic of the sheet-like member. Further, the outer edge of the inspection object 170 can be easily operated by simply bringing the object 170 to be inspected sandwiched between the mounting plate 10 and the sandwiching plate 30 and the dimension inspection gauge part 140 into contact with the positioning unit 20. The positions of the two sides 170a, 170b of the portion and the positions of the two sides (the first gauge reference surface 143a and the second gauge reference surface 143b) of the edge of the penetrating portion 141 in the dimension inspection gauge portion 140 are Z-axis direction. Can be made to match in plan view. In the dimension inspection instrument 1 in which the inspection object 170 is set in such a state, as shown in FIGS. 8A to 8C, the outer edge portion 170a of the inspection object 170 and the dimension inspection gauge section 140 penetrate. The size and shape can be easily inspected simply by observing the presence or absence of gaps G1 and G2 between the edges of the portion 141 (maximum allowable dimension inspection part 141a and minimum allowable dimension inspection part 141b). As a result, even if it is a sheet-like member, a dimension can be confirmed correctly and easily.

  In addition to the configuration of the dimension inspection instrument 1 of the above embodiment, a dimension inspection instrument 201 including a light source unit 80 as shown in FIG. 9 may be used. The light source unit 80 is a portion that is provided at a position facing the surface of the mounting plate 10 opposite to the surface on which the inspection object 70 (170) is mounted, and emits light to the mounting plate 10 side. In the light source unit 80, a light source 83 is disposed in a housing 81, and the light source 83 emits light toward the mounting plate 10 (upward in the Z-axis direction). The upper surface 85 of the housing 81 is preferably formed of a translucent material that can convert light emitted from the light source 83 into planar light. By providing the light source part 80, it can be set as the dimension test | inspection instrument 201 which is easier to confirm the presence or absence of the clearance gap G (G1, G2).
