Description

Technical Field

[0001] The present invention relates to a method for manufacturing a positioning jig in which a plurality of positioning pins for supporting an object are arranged on a support base.

Background Art

[0002] In the manufacture of various products, for example, when performing processing such as welding, the object is positioned using a positioning jig for processing. The positioning jig has a configuration in which, for example, a plurality of positioning pins for supporting the object are arranged on a support base, and is made compatible with various objects by adjusting the positions of the positioning pins according to the object. This positioning jig is manufactured, for example, by actually disposing the object on the support base and arranging a plurality of positioning pins on the object so as to support a predetermined position of the object.

[0003] However, in this method, since the object must be actually placed on the support base, the position of the positioning pins cannot be adjusted without the actual object. Therefore, it is not possible to manufacture the positioning jig until the object is actually produced, and it takes time until the production of the positioning jig starts. As a result, there is a problem that it is difficult to quickly respond to design changes of the product.

[0004] Note that Patent Document 1 describes a jig design support device that has a positioning block and a clamp and supports the design of a jig for fixing a workpiece, and designs a virtual model of a jig that automatically adjusts the dimensional shape of a three-dimensional model of the positioning block and the clamp according to the workpiece dimensional shape. However, in the method described in Patent Document 1, it is necessary to reflect the dimensional shape adjusted in the three-dimensional virtual space once on the actual jig, and there is a problem that it is difficult to quickly respond in real time to design changes of the product.

MEANS FOR SOLVING THE PROBLEMS

[0007] The method for manufacturing a positioning jig of the present invention manufactures a positioning jig in which a plurality of positioning pieces for supporting an object are arranged on a support base. Using an information processing system that overlays an image of a virtual object on an image of the real space photographed by photographing means and displays it on a display means, the real space including the support base is photographed by the photographing means, and the image of the real space and the image of the virtual object of the object are overlaid by the information processing system.

Embodiments for Carrying Out the Invention

[0011] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0012] FIG. 1 shows the flow of the procedure for manufacturing a positioning jig according to an embodiment of the present invention. FIG. 2 shows an example of the configuration of the positioning jig. FIG. 3 is for explaining one procedure in the manufacturing method of the positioning jig shown in FIG. 1, and FIG. 4 shows an example of a composite image in one procedure shown in FIG. 3. FIG. 5 is for explaining another procedure in the manufacturing method of the positioning jig shown in FIG. 1, and FIG. 6 shows an example of a composite image in one procedure shown in FIG. 5. In FIGS. 4 and 6, the virtual object M of the object is shaded, and the portion of the positioning piece 11 on which the virtual object M is superimposed is represented by a dashed line.

[0013] This method for manufacturing a positioning jig manufactures a positioning jig 10 in which a plurality of positioning pieces 11 for supporting an object are arranged on a support base 12. The positioning jig 10 is, for example, used to place and position the object when processing the object. The positioning piece 11 has, for example, a disposition portion 11A disposed on the support base 12 at one end, and a pin 11B inserted into a positioning hole provided in the object at the other end. The disposition portion 11A is configured to be inserted into a disposition hole 12A provided in the support base 12 with a protruding portion protruding downward and fixed by fixing means.

[0014] Between the disposition portion 11A and the pin 11B, a connection portion 11E connecting, for example, a first connection member 11C and a second connection member 11D is provided. The connection portion 11E is configured to be able to adjust the overall length by changing the connection position of the second connection member 11D with respect to the first connection member 11C and thereby adjust the position of the pin 11B in the height direction. The pin 11B is disposed, for example, via a third connection member 11F with respect to the second connection member 11D. The pin 11B is attached to one end side of the third connection member 11F, and the second connection member 11D is attached to the other end side.

[0015] The third connecting member 11F is, for example, rotatable with respect to the first connecting member 11C, whereby the position of the pin 11B with respect to the arrangement portion 11A can be changed. Further, on the support surface of the support base 12, a plurality of arrangement holes 12A for arranging the positioning piece 11 are provided so as to correspond to the positioning holes of the object and extend in a predetermined direction. Thereby, the position of the arrangement portion 11A with respect to the support base 12 can be changed by changing the position of the pin 11B.

[0016] In the manufacturing method of this positioning jig, the positioning piece 11 is arranged on the support base 12 by using an information processing system 23 that superimposes the image of the virtual object M on the image of the real space photographed by the photographing means 21 and displays it on the display means 22. The information processing system 23 uses, for example, a so-called AR (Augmented Reality) technology that superimposes an image by computer graphics on the image of the real space to expand the reality. The information processing system 23 is, for example, configured by a computer and is configured to function as the information processing system 23 by executing a program, and known AR technology can be used.

[0017] The photographing means 21 can obtain, for example, a two-dimensional digital image and is configured by a camera. The display means 22 is configured by a display, for example. The photographing means 21, the display means 22, and the information processing system 23 may be configured individually, but may be integrally configured by, for example, a mobile terminal having these. Further, a mobile terminal having the photographing means 21, the display means 22, and the information processing system 23 may be used, and another photographing means 21, display means 22, or information processing system 23 may be used together with the mobile terminal.

[0018] The manufacturing method of this positioning jig includes photographing the real space including the support base 12 by the photographing means 21, superimposing the image of the real space and the image of the virtual object M of the object by the information processing system 23, and based on the obtained composite image, a positioning piece arranging procedure (step S100) for arranging the positioning piece 11 on the support base 12. The positioning piece arranging procedure preferably includes, for example, photographing the real space including the support base 12 from above by the photographing means 21, and based on the composite image obtained by the information processing system 23, a horizontal direction positioning procedure (step S110) for determining the position of the positioning piece 11 in the horizontal direction, and after the horizontal direction positioning procedure, photographing the real space including the support base 12 from the horizontal direction by the photographing means 21, and based on the composite image obtained by the information processing system 23, a height determination procedure (step S120) for determining the height of the positioning piece 11.

[0019] In the horizontal direction positioning procedure (step S110), first, for example, as shown in FIG. 3, the photographing means 21 is arranged above the support base 12, and the real space including the support base 12 is photographed from above by the photographing means 21 (step S111). The photographing by the photographing means 21 is preferably a moving image. Next, for example, by the information processing system 23, the image of the real space (for example, a moving image) obtained by the photographing means 21 and the image of the virtual object M of the object are superimposed, and the composite image (for example, a composite moving image) is displayed on the display means 22 (step S112). At this time, for example, the operator adjusts the position where the image of the real space and the image of the virtual object M of the object are superimposed, specifically, for example, the positional relationship between the support base 12 and the virtual object M of the object in the composite image.

[0020] Subsequently, for example, based on the composite image (e.g., composite video) displayed on the display means 22 (see FIG. 4 for example), the operator aligns the pin portion 11B with the virtual positioning hole M1 of the virtual object M of the object and places the positioning piece 11, and fixes it to the support base 12 (step S113). At this time, when the operator moves the positioning piece 11 onto the support base 12, the positioning piece 11 appears in the image (e.g., video) of the real space. Therefore, while looking at the composite image (e.g., composite video), the operator can align the pin portion 11B of the positioning piece 11 with the virtual positioning hole M1 of the virtual object M of the object.

[0021] Also, in the height determination procedure (step S120), first, for example, as shown in FIG. 5, the imaging means 21 is arranged on the side of the support base 12, and the imaging means 21 captures the real space including the support base 12 from the horizontal direction (step S121). It is preferable that the imaging by the imaging means 21 is a video. Next, for example, the information processing system 23 superimposes the image (e.g., video) of the real space obtained by the imaging means 21 and the image of the virtual object M of the object, and displays the composite image (e.g., composite video) on the display means 22 (step S122). At this time, for example, the operator adjusts the position where the image of the real space and the image of the virtual object M of the object are superimposed, specifically, for example, the positional relationship between the support base 12 and the virtual object M of the object in the composite image.

[0022] Subsequently, for example, based on the composite image (e.g., composite video) displayed on the display means 22 (see FIG. 6 for example), the operator adjusts the height of the pin portion 11B by the connecting portion 11E so that the height of the virtual object M of the object and the pin portion 11B match (step S123). At this time, since the positioning piece 11 also appears in the image (e.g., video) of the real space, the operator can adjust the height of the pin portion 11B while looking at the composite image (e.g., composite video). Note that the height determination procedure is repeated by changing the imaging direction by the imaging means 21 as necessary according to the position of the positioning piece 11, for example.

[0023] In addition, the image of the virtual object M of the object in the information processing system 23 is preferably created from the design drawing of the object. This is because if the virtual object M is created from the design drawing, the positioning jig 10 can be manufactured before the actual object of the object is produced at the stage when the design drawing of the object is completed.

[0024] As described above, according to the present embodiment, the information processing system 23 that overlays and displays the image of the virtual object M on the image of the real space photographed by the photographing means 21 is used, and the positioning piece 11 is arranged on the support base 12 based on the composite image in which the image of the virtual object M of the object is overlaid on the image of the real space including the support base 12. Therefore, the positioning jig 10 can be manufactured even without the actual object of the object. Thus, the time until the start of manufacturing the positioning jig 10 can be shortened, and the product design change and the like can be quickly responded to.

[0025] In addition, photograph the real space including the support base 12 from above, and based on the composite image obtained by the information processing system 13, a horizontal direction positioning procedure (step S110) for determining the position of the positioning piece 11 in the horizontal direction, and after the horizontal direction positioning procedure, photograph the real space including the support base 12 from the horizontal direction, and based on the composite image obtained by the information processing system 13, a height determination procedure (step S120) for determining the height of the positioning piece 11 are included, then the position and height of the positioning piece 11 can be easily adjusted.

[0026] As described above, the present invention has been described with reference to the embodiments, but the present invention is not limited to the above embodiments and can be variously modified. For example, in the above embodiments, the procedures have been specifically described, but the specific contents of the procedures may be different, and other procedures may also be included. Further, in the above embodiments, the configuration of the positioning jig 10 has been specifically described, but it may have other configurations.
