This component assembly jig has a plurality of plate-like body support parts that support the plate-like body, and an assembly judgment part that judges whether the plurality of parts to be assembled have been assembled properly to the plate-like body. Each of the plurality of plate-like body support parts is provided with a hollow part that accommodates the protrusions, and has an assembly part detector that detects the parts to be assembled inside the hollow part, and is configured so that the open end face of the hollow part abuts against the plate-like body. The assembly judgment part makes the judgment based on the detection state of the assembly part detector of the plurality of plate-like body support parts.

Description

[Technical field]

[0001] The present invention relates to a part assembly jig used when assembling parts onto a plate-like body. [Background technology]

[0002] In recent years, with the development of CAD (Computer Aided Design) technology, plate-shaped components (plate-shaped members) with complex shapes have come to be used more and more. In particular, in transportation machinery such as automobiles, there is a demand to optimize the shapes of individual parts in order to improve energy efficiency, and plate-shaped members with complex shapes have come to be used more and more.

[0003] Furthermore, when various plate-like members are attached to a structure such as a chassis, cushioning members such as rubber bushings are attached to the locations where fastening parts such as bolts are attached in order to suppress the generation of abnormal noises due to vibrations, etc. When cushioning members are attached in this way, even if the plate-like member itself has a flat shape, the plate-like structure (plate-like body) as a whole to which the cushioning members are attached will have parts protruding from the plate-like member (protruding parts), making the shape complex.

[0004] Usually, when a plate-like body is attached to a structure, fastening parts are attached to the plate-like body in advance, and after the process of attaching the fastening parts (assembly process), an inspection process is performed to determine whether the fastening parts have been attached properly. When the plate-like body has a complex shape, such as when a plate-like member with a complex shape is used or when the plate-like body has a protruding portion, it is not necessarily easy to determine whether the fastening parts have been attached properly. Therefore, whether the fastening parts have been attached properly to a plate-like body with a complex shape is determined using, for example, a laser displacement sensor (see Non-Patent Document 1).

[0005] However, when multiple fastening parts are to be assembled to a plate-like body, there is a risk of nonconformity, such as missing fastening parts. Although such nonconformity can be corrected in the assembly process, if the assembly is judged to be improper in the inspection process, the assembly process and the inspection process will be performed again, resulting in an increase in turnaround time. In order to prevent such an increase in turnaround time, it is desirable to judge in the assembly process whether multiple fastening parts are properly assembled to the plate-like body. [Prior art documents] [Non-patent literature]

[0006] [Non-Patent Document 1] "Kaizen Case Studies", Keyence Corporation, 2000, p.5 Summary of the Invention [Problem to be solved by the invention]

[0007] However, in the assembly process, it is difficult to determine whether or not multiple fastening parts have been properly assembled to a plate-like body using the method described in Non-Patent Document 1. This problem is common to processes in which multiple fastening parts are assembled to a plate-like body, as well as processes in which a multiple number of various parts are assembled to a plate-like body having a protruding portion so as to penetrate the plate-like body.

[0008] The present invention has been made to solve the above-mentioned problems in the conventional art, and makes it possible to determine whether or not multiple parts have been properly assembled on a plate-like body having a protrusion when the parts are assembled on the plate-like body. [Means for solving the problem]

[0009] In order to achieve at least part of the above objects, the present invention can be realized in the following forms or application examples.

[0010] [Application example 1] 1. A component assembly jig for assembling a plurality of assembly parts to a plate-like body having a plurality of protrusions protruding in a predetermined surface direction so as to penetrate the plate-like body in the predetermined surface direction at each position of the plurality of protrusions, the component assembly jig comprising: a plurality of plate-like body support parts for supporting the plate-like body; and an assembly judgment part for judging whether the plurality of assembly parts have been properly assembled onto the plate-like body, each of the plurality of plate-like body support parts having a hollow part for accommodating the protrusions and an assembly part detector for detecting the assembly parts inside the hollow part, the open end face of the hollow part being configured to abut against the plate-like body, and the assembly judgment part makes the judgment based on a detection state of the assembly part detector of the plurality of plate-like body support parts.

[0011] By using the part assembly jig of this application example, when a plurality of parts to be assembled are assembled to a plate-like body, it can be determined whether or not the plurality of parts to be assembled have been assembled properly to the plate-like body.

[0012] [Application example 2] The component assembly jig according to Application Example 1, further comprising a plate-shaped body detection unit that detects the plate-shaped body in a state where the plate-shaped body is arranged in contact with the open end faces of the plurality of plate-shaped body support parts, and the assembly judgment unit further performs the judgment based on a detection state of the plate-shaped body detection unit.

[0013] According to this application example, by appropriately setting the shape and arrangement of the plate-shaped object detection unit, it is possible to prevent an improper plate-shaped object having a different shape from a proper plate-shaped object from being attached to the part assembly jig, or to prevent an improper plate-shaped object from being detected when attached to the part assembly jig. Therefore, even if an improper plate-shaped object is mistakenly mixed in, it is possible to prevent the improper plate-shaped object from being determined to be proper and sent to the next process.

[0014] [Application example 3] The component assembly jig according to application example 1 or 2, further comprising a determination result indicator lamp whose lighting state is set according to the result of the determination.

[0015] According to this application example, it is possible to check whether or not the part to be attached has been properly attached to the plate-shaped body based on the lighting state of the determination result indicator lamp.

[0016] [Application example 4] A component assembly jig according to Application Example 1 or 2, wherein the plurality of plate-shaped body support portions each have an assembly status indicator light whose lighting state is set according to the detection state of the component to be assembled detector.

[0017] According to this application example, the location where the part to be assembled should be installed can be ascertained based on the lighting state of the assembly state display, etc., so that when there are a large number of parts to be assembled, the parts can be assembled more quickly.

[0018] [Application example 5] A component assembly support device comprising: the component assembly jig according to Application Example 1 or 2; a camera that photographs the plate-like body placed in contact with the open end faces of the plurality of plate-like body support parts; and a plate-like body judgment unit configured to judge whether the plate-like body is appropriate or not based on the image photographed by the camera, wherein the component assembly support device judges whether the assembly of the plurality of assembly parts to the plate-like body has been performed appropriately or not based on the judgment result by the assembly judgment unit and the judgment result by the plate-like body judgment unit.

[0019] According to this application example, it is possible to suppress the occurrence of non-conforming products caused by the plate-shaped body at the stage of assembling the assembly part to the plate-shaped body.

[0020] The present invention can be realized in various forms, for example, as a part assembly jig, a part assembly support device using the part assembly jig, and an assembly method for assembling a part to be assembled on a plate-like body using the jig or device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Hereinafter, embodiments of the present invention will be described in the following order. A. First embodiment: B. Second embodiment: C. Variations:

[0023] A. First embodiment: FIG. 1 is an external perspective view showing the appearance of a part assembly jig 10 according to a first embodiment. This part assembly jig 10 is used to assemble a predetermined part (hereinafter also referred to as an "assembly part") to a plate-like body having a substantially plate shape. The configuration of the plate-like body and the assembly part, and the usage and operation of the part assembly jig 10 when assembling the assembly part to the plate-like body will be described later. In each drawing including FIG. 1, the X and Y directions represent two horizontal directions perpendicular to each other, and the Z direction represents the vertical upward direction. Therefore, hereinafter, the +Z direction is also referred to as "upward" or simply "upward", and the -Z direction is also referred to as "downward" or simply "downward".

[0024] 1, the component assembly jig 10 includes a base plate 11, and three plate-like body support units 100, 200, and 300, each of which is fixed to the upper surface of the base plate 11, a plate-like body detection unit 400, a determination display unit 500, and a battery box 600. Note that the determination display unit 500 is connected to each of the three plate-like body support units 100, 200, and 300, the plate-like body detection unit 400, and the battery box 600 via wiring, but these wiring is not shown in FIG. 1 and other drawings.

[0025] Although details will be described later, the three plate-like body support parts 100, 200, 300 are configured to support a plate-like body by contacting the plate-like body to which the assembly parts are to be assembled. These plate-like body support parts 100, 200, 300 have the same configuration. Therefore, the last two digits of the reference numerals attached to similar parts in the plate-like body support parts 100, 200, 300 are the same, and the following description will be given using one of the plate-like body support parts 100, 200, 300, and the description of the other plate-like body support parts will be omitted.

[0026] As shown in FIG. 1, the plate-shaped body support portion 100 has a base portion 110 attached to the upper surface of the base plate 11, an abutment portion 120 attached to the upper side of the base portion 110 and abutting the plate-shaped body, a limit switch 130, and an LED lamp 140 as an indicator light.

[0027] The pedestal portion 110 is a member whose outer shape (outer peripheral shape) in a cross section taken along a horizontal plane (XY plane) is convex, and is composed of a flat bottom plate portion 111 provided on the lower end side thereof, and a hollow tubular portion 112 extending upward from the outer edge of the bottom plate portion 111. The bottom plate portion 111 is provided with a through hole (not shown) penetrating in the up-down direction, and the pedestal portion 110 is attached to the base plate 11 by a screw passing through the through hole. The lower end portion of the pedestal portion 110 is also provided with an opening portion 119 that opens in the -Y direction.

[0028] The abutment portion 120 is composed of a flat flange portion 121 whose outer shape is the same convex shape as the outer peripheral shape of the base portion 110, and a substantially cylindrical tubular portion 122 disposed above the flange portion 121. The flange portion 121 constituting the abutment portion 120 is provided with a through hole (not shown) penetrating in the vertical direction, and the abutment portion 120 is attached to the base portion 110 by a screw passing through the through hole.

[0029] The cylindrical portion 122 is provided with a through hole 128 that penetrates from the outer periphery side of the cylindrical portion 122 to the inner hollow portion 129, and the limit switch 130 is disposed so as to extend from the outer periphery side of the cylindrical portion 122 to the hollow portion 129 through the through hole 128. In addition, below the end portion of the limit switch 130 in the -Y direction, the flange portion 121 is provided with a through hole (not shown) that penetrates in the vertical direction, and wiring connected to the limit switch 130 is introduced into the base portion 110 through the through hole.

[0030] Furthermore, in the convex flange 121, a protruding portion located at the end in the -X direction is provided with a through hole (not shown) that penetrates in the vertical direction and corresponds to the position of the lead wire of the LED lamp 140. Through this through hole, the lead wire of the LED lamp 140 is introduced into the base 110 and connected to the wiring.

[0031] In this way, the wiring connected to the limit switch 130 introduced inside the base portion 110 and the wiring connected to the lead wire of the LED lamp 140 inside the base portion 110 are taken out to the outside of the base portion 110 (plate-shaped body support portion 100) through an opening 119 provided at the lower end of the base portion 110.

[0032] The plate-like object detection section 400 has a base section 410 attached to the upper surface of the base plate 11, and a sensor section 420 attached to the upper side of the base section 410 and having a sensor for detecting a plate-like object.

[0033] The pedestal portion 410 is a member whose outer periphery is rectangular, and is composed of a flat bottom plate portion 411 provided on the lower end side thereof, and a hollow tubular portion 412 extending upward from the outer edge of the bottom plate portion 411. The bottom plate portion 411 is provided with a through hole (not shown) that penetrates in the up-down direction, and the pedestal portion 410 is attached to the base plate 11 by a screw that passes through the through hole. The lower end portion of the pedestal portion 410 is also provided with an opening portion 419 that opens in the -Y direction.

[0034] Sensor unit 420 is composed of flange portion 421 in the form of a rectangular flat plate, and columnar portion 422 in the form of a square column arranged above flange portion 421. Flange portion 421 constituting sensor unit 420 is provided with a through hole (not shown) penetrating in the up-down direction, and sensor unit 420 is attached to base portion 410 by a screw passing through the through hole.

[0035] A sensor hole 429 is provided near the center of columnar portion 422, and a reflective photoelectric sensor (reflective sensor) (not shown) is disposed at the bottom of sensor hole 429. The reflective sensor is a sensor that detects an object by emitting light and detecting the light that is reflected by the object and enters the sensor hole 429. In the first embodiment, by providing the reflective sensor at the bottom of sensor hole 429, it is possible to suppress erroneous detection caused by external light entering the reflective sensor.

[0036] The wiring connected to the reflection sensor is introduced into the inside of the base part 410 through a through hole (not shown) that penetrates downward from the bottom of the sensor hole 429. Then, the wiring introduced into the inside of the base part 410 is taken out to the outside of the base part 410 (plate-shaped body detection part 400) through the opening part 419.

[0037] In the example of Figure 1, the upper end surface of the columnar portion 422 is inclined so that the +Y side faces upward (+Z direction); however, in general, the inclination direction of the upper end surface of the columnar portion is set to match the inclination direction of the lower surface of the plate-like body placed at the top of the component assembly jig 10 at the position of the plate-like body detection unit.

[0038] The judgment display unit 500 has a housing 501, an LED lamp 502 arranged on the top surface of the housing 501, and a character section 503 indicating "Judgment result" and "OK". Inside the housing 501, a microcomputer (not shown) having a CPU, ROM, RAM, and an input / output interface is arranged. This microcomputer is driven by power from a battery box 600.

[0039] The input / output interface of the microcomputer is connected to the limit switches 130, 230, 330 and LED lamps 140, 240, 340 of the three plate-like object supporting units 100, 200, 300, respectively, the reflection sensor of the plate-like object detecting unit 400, and the LED lamp 502 of the determination display unit 500.

[0040] Fig. 2 is an explanatory diagram showing the configuration of a plate-shaped body 900 to which components are to be assembled using the component assembly jig 10 (Fig. 1). Fig. 2(a) is an external perspective view showing the shape of a plate-shaped member 950 constituting the plate-shaped body 900, and Fig. 2(b) is an external perspective view showing the overall configuration of the plate-shaped body 900.

[0041] 2(a), plate-like member 950 constituting plate-like body 900 is a plate-like member curved in the Y direction. Further, at the -X direction end and +X direction end of the +Y direction end of plate-like member 950, through holes 959, 958 penetrating approximately in the vertical direction (Z direction) are provided, respectively. Further, at the -X direction end of the -Y direction end of plate-like member 950, a through hole 957 penetrating approximately in the vertical direction is provided.

[0042] 2(b), rubber bushings 910, 920, 930 are attached to the three through holes 959, 958, 957 provided in the plate-like member 950. The rubber bushings 910, 920, 930 each have a first large diameter portion 911, 921, 931 and a second large diameter portion 912, 922, 932, each having a large outer diameter, and a small diameter portion (not shown) disposed therebetween and having a thickness and outer diameter set to be substantially the same as the thickness of the plate-like member 950 and the inner diameter of the through holes 959, 958, 957.

[0043] Therefore, in the plate-like body 900 in which the rubber bushes 910, 920, 930 are attached to the plate-like member 950, the first large diameter portions 911, 921, 931 of the rubber bushes 910, 920, 930 protrude downward from the plate-like member 950, and the second large diameter portions 912, 922, 932 protrude upward from the plate-like member 950. Note that since the first large diameter portions 911, 921, 931 of the rubber bushes 910, 920, 930 protrude downward from the plate-like member 950 in this manner, they can also be referred to as protruding portions 911, 921, 931 protruding downward from the plate-like member 950, respectively.

[0044] Furthermore, rubber bushings 910, 920, 930 attached to through holes 959, 958, 957 of plate-like member 950 are provided with center holes 919, 929, 939, respectively. Therefore, plate-like body 900 is provided with through holes (i.e., center holes 919, 929, 939) that penetrate substantially in the vertical direction.

[0045] 3 is an external perspective view showing the appearance of the component assembly jig 10 and the plate-shaped body 900 in a state in which the plate-shaped body 900 is attached to the component assembly jig 10. When the plate-shaped body 900 is attached to the component assembly jig 10, large diameter portions 911, 921, 931 (FIG. 2) on the lower surface sides of rubber bushes 910, 920, 930 attached to the plate-shaped body 900 are housed in hollow portions 129, 229, 329 (FIG. 1) provided in cylindrical portions 122, 222, 322 of the corresponding plate-shaped body supports 100, 200, 300, respectively.

[0046] In this way, the large diameter portions 911, 921, 931 of the rubber bushings 910, 920, 930 are fitted into the hollow portions 129, 229, 329 of the plate-shaped body support portions 100, 200, 300, and in order to ensure that the plate-shaped body 900 is stably held in the component assembly jig 10, the inner diameters of the hollow portions 129, 229, 329 are set to be the same as or slightly larger than the large diameter portions 911, 921, 931 of the rubber bushings 910, 920, 930.

[0047] 3, when the plate-shaped body 900 is attached to the component assembling jig 10, the plate-shaped member 950 of the plate-shaped body 900 is adjacent to the sensor unit 420 (FIG. 1) of the plate-shaped body detection unit 400. Therefore, when the plate-shaped body 900 is attached to the component assembling jig 10, light emitted from the reflection sensor is reflected by the plate-shaped member 950 and enters the reflection sensor provided in the sensor unit 420. Therefore, by detecting whether or not the reflected light enters the reflection sensor provided in the plate-shaped body detection unit 400, the component assembling jig 10 can detect whether or not the plate-shaped body 900 has been attached.

[0048] Fig. 4 is an external perspective view showing the appearance of the part assembly jig 10, the plate-shaped body 900, and the parts to be assembled 810, 820, and 830 in a state in which the three parts to be assembled 810, 820, and 830 are assembled to the plate-shaped body 900. In the example of Fig. 4, bolts 811, 821, and 831 and washers 812, 822, and 823 passed through the bolts 811, 821, and 831 are assembled to the plate-shaped body 900 as the parts to be assembled 810, 820, and 830, respectively.

[0049] The assembly parts 810 , 820 , 830 are assembled to the plate-like body 900 such that the threaded portions of the respective bolts 811 , 821 , 831 pass downward through central holes 919 , 929 , 939 ( FIG. 3 ) provided in the rubber bushings 910 , 920 , 930 of the plate-like body 900 .

[0050] In addition, the inner diameters of the central holes 919, 929, 939 of the rubber bushings 910, 920, 930 are set slightly smaller than the outer diameters of the bolts 811, 821, 831 so as to prevent the assembly parts 810, 820, 830 from falling off the plate-like body 900 after the assembly parts 810, 820, 830 are assembled to the plate-like body 900.

[0051] Fig. 5 is an explanatory diagram showing how a part to be attached 820 is attached to a plate-like body 900 using the part assembly jig 10 (Fig. 1). Fig. 5(a) to Fig. 5(c) are partial cross-sectional views of the vicinity of the plate-like body support part 200 on the cutting plane A shown in Figs. 1, 3 and 4, respectively.

[0052] As described above, in the plate-like body support portion 200, the limit switch 230 is disposed so as to extend from the outer periphery side of the cylindrical portion 222 to the hollow portion 229 through the through hole 228 that penetrates from the outer periphery side of the cylindrical portion 222 to the hollow portion 229. Then, as shown in FIG. 5(a), the plunger 231 of the limit switch 230 is disposed approximately in the center of the hollow portion 229.

[0053] 5(a), when no load is applied to the plunger 231 and the plunger 231 is not pushed in, the limit switch 230 is in the OFF state. Then, the determination display unit 500 (FIG. 1) to which the limit switch 230 is connected determines that the assembly part 820 is not assembled, and the LED lamp 240 of the plate-shaped body support part 200 and the LED lamp 502 of the determination display unit 500 are turned off.

[0054] 5(b), in a state where the plate-shaped body 900 is attached to the component assembly jig 10, as described above, the lower large diameter portion 921 of the rubber bushing 920 attached to the plate-shaped body 900 is housed in the hollow portion 229. This prevents the plate-shaped body 900 from moving significantly in the X and Y directions relative to the base plate 11.

[0055] Further, the lower surface of the plate-like member 950 of the plate-like body 900 abuts against the upper end surface (the opening end surface of the hollow portion 229) of the tubular portion 222 of the plate-like body support portion 200. This restricts the movement of the plate-like body 900 in the -Z direction (downward) relative to the base plate 11, and suppresses the plate-like body 900 from rattling.

[0056] In this way, the movement and rattling of the plate-like body 900 relative to the base plate 11 is suppressed, so that the plate-like member 950 constituting the plate-like body 900 is curved as shown in Fig. 2, and even if a protruding portion such as the large diameter portion 921 of the rubber bushing 920 exists below, the plate-like body 900 is stably held by the component assembling jig 10 (Fig. 1). Therefore, by using the component assembling jig 10, it is possible to insert the threaded portion of the bolt 821 into the center hole 929 of the rubber bushing 920, and to assemble the component 820 to the plate-like body 900 more easily.

[0057] 5(b), when the plate-shaped body 900 is attached to the component assembly jig 10, the light reflected by the plate-shaped body 900 (plate-shaped member 950) is incident on the reflection sensor of the plate-shaped body detection unit 400 (FIG. 1) as described above. Therefore, the determination display unit 500 to which the reflection sensor is connected determines that the plate-shaped body 900 is attached to the component assembly jig 10.

[0058] 5(c), when the mounting part 820 is properly mounted on the plate-like body 900 and the washer 822 is sandwiched between the rubber bushing 920 and the head of the bolt 821, the plunger 231 of the limit switch 230 is pushed in by the tip of the bolt 821 (the tip of the mounting part 820). This switches the limit switch 230 from the OFF state to the ON state.

[0059] When the limit switch 230 is switched to the on state, the judgment display unit 500 (FIG. 1) to which the limit switch 230 is connected judges that the part to be attached 820 has been properly attached, and the LED lamp 240 of the plate-shaped body support part 200 turns on. In this way, when the LED lamp 240 turns on, it can be confirmed that the attachment of the part to be attached 820 has been completed at the position of the plate-shaped body support part 200.

[0060] In the first embodiment, the LED lamp 240 is turned on when the limit switch 230 is turned on, but generally, the lighting state may be set according to the on / off state of the limit switch 230, i.e., the detection state of the parts to be assembled by the limit switch 230. For example, the LED lamp 240 may be turned off when the limit switch 230 is turned on. In this case, the parts to be assembled that need to be attached can be confirmed by the lit LED lamp, so that when there are a large number of parts to be assembled, the parts to be assembled can be assembled more quickly.

[0061] In this way, by providing the LED lamp 240 on the contact portion 220 (plate-shaped body support portion 200), the work of assembling the assembly parts to the plate-shaped body becomes easier, but it is also possible to omit the LED lamp.

[0062] As described above, when the judgment display unit 500 judges that the plate-shaped body 900 is attached to the component assembly jig 10 and the other limit switches 130, 330 are turned on, the judgment display unit 500 judges that all of the assembly parts 810, 820, 830 (Figure 4) have been properly assembled to the plate-shaped body 900, and the LED lamp 502 of the judgment display unit 500 turns on.

[0063] As can be seen from FIG. 5(c), the dimensions of each part, such as the height (length in the Z direction) of the tubular part 222 of the abutment part 220, the thickness of the flange part 221, and the height of the base part 210, are appropriately set depending on the shapes of the limit switch 230, the rubber bushing 920, and the mounting part 820, and the thickness of the plate-like member 950.

[0064] In this way, the component assembly jig 10 (FIG. 1) of the first embodiment makes it easier to assemble the components 810, 820, 830 (FIG. 4) to the plate-like body 900, and makes it possible to check whether the components 810, 820, 830 have been properly assembled to the plate-like body 900 by checking the illumination state of the LED lamp 502 of the judgment display unit 500.

[0065] Then, in a process (assembly process) of assembling the parts to be attached 810, 820, 830 to the plate-like body 900, it is possible to check whether the parts to be attached 810, 820, 830 have been properly assembled to the plate-like body 900. Therefore, since a process (inspection process) of determining whether the parts to be attached 810, 820, 830 have been properly assembled to the plate-like body 900 after the assembling process can be omitted, the entire process can be simplified.

[0066] Furthermore, although an assembly omission or the like of an assembly part can be corrected in the assembly process, if the assembly is determined to be improper in the inspection process, the assembly process and the inspection process will be carried out again, resulting in an increase in turnaround time. However, according to the first embodiment, the occurrence of problems that can be corrected in the assembly process is suppressed in the assembly process, making it possible to shorten the turnaround time.

[0067] In the first embodiment, the LED lamp 502 is provided in the judgment display unit 500, and the lighting state of the LED lamp 502 is set to display whether the parts to be assembled 810, 820, 830 are properly assembled to the plate-like body 900 or not. However, a sound generating device such as a buzzer may be provided to notify by voice when it is determined that all the parts to be assembled 810, 820, 830 are properly assembled to the plate-like body 900. In this case, the LED lamp 502 may be omitted. However, it is preferable to set the lighting state of the indicator lamp according to the judgment result as in the first embodiment, in order to recognize which part assembly jig is judged to be proper when the parts to be assembled are assembled using a plurality of part assembly jigs at one location.

[0068] Furthermore, the judgment result may be sent to an external device without displaying the LED lamp 502 or notifying with a buzzer or the like. For example, instead of the judgment display unit 500, an assembly judgment unit that judges whether all the parts to be attached 810, 820, 830 have been properly assembled to the plate-like body 900 may be provided, and the judgment result may be sent to a control device of a production line or the like. Note that the judgment display unit 500 has a function of judging whether all the parts to be attached 810, 820, 830 have been properly assembled to the plate-like body 900, and therefore the judgment display unit 500 can be interpreted as including an assembly judgment unit.

[0069] B. Second embodiment: Fig. 6 is an explanatory diagram showing the configuration of a component assembly support device 1a using a component assembly jig 10a. As shown in Fig. 6, the component assembly support device 1a includes the component assembly jig 10a, a camera 710a, and a computer 720a.

[0070] The component assembly jig 10a used in the second embodiment differs from the component assembly jig 10 (FIG. 1) of the first embodiment in that the battery box 600 is omitted, the determination display unit 500a is disposed closer to the +X direction side, and the determination display unit 500a is connected to a computer 720a. Since the other points are the same as those of the component assembly jig 10 of the first embodiment, the description thereof will be omitted here.

[0071] In the example shown in Fig. 6, a plate-shaped body 900a having a part number sticker 951a with a part number "123-456" affixed to a plate-shaped member 950a is attached to the part assembly jig 10a. This plate-shaped body 900a differs from the plate-shaped body 900 of the first embodiment (Figs. 2 to 4) in that a part number sticker 951a is affixed to the plate-shaped member 950a. Other points are similar to the plate-shaped body 900 of the first embodiment, and therefore a description thereof will be omitted here. Also, in the example shown in Fig. 6, a part number sticker 951a with a part number affixed to the plate-shaped member 950a, but the part number may be engraved on the plate-shaped member.

[0072] Camera 710a is disposed above plate-like body 900a, and captures an image of the area including plate-like body 900a. Then, camera 710a captures an image of plate-like body 900a, and transmits the captured image to computer 720a.

[0073] The computer 720a analyzes the image sent from the camera 710a and judges whether the plate-like body 900a attached to the component assembly jig 10a is appropriate or not. The judgment of the suitability of the plate-like body attached to the component assembly jig 10a is realized by various well-known methods. In this way, since the function of analyzing the image and judging the suitability of the plate-like body is realized by the computer 720a, it can also be said that the computer 720a has a plate-like body judgment unit that judges the suitability of the plate-like body based on the image.

[0074] For example, machine learning can be performed using an image when the appropriate plate-like body 900a is attached, and the appropriateness of the plate-like body can be determined using the learning data generated by the machine learning. Also, during machine learning, it is possible to generate learning data for determining the appropriateness of the plate-like body by using an image when an inappropriate plate-like body is attached in addition to an image when the appropriate plate-like body 900a is attached.

[0075] Also, instead of using machine learning, a conventional method can be used in which feature points are extracted from an image and the suitability of the plate-like body is judged based on the extracted feature points and a reference feature point. Furthermore, feature points can be extracted by machine learning and the suitability of the plate-like body can be judged based on the extracted feature points and a reference feature point. For example, the product number written on the product number sticker can be recognized using machine learning, and the recognized product number can be compared with the product number of the appropriate plate-like body 900a to judge the suitability of the plate-like body.

[0076] In this way, after the computer 720a judges whether the plate-like body attached to the component assembly jig 10a is proper or not, the judgment result is sent from the computer 720a to the judgment display unit 500a. The judgment display unit 500a judges whether the plate-like body is proper or not based on the judgment result sent from the computer 720a, the on / off states of the limit switches 130, 230, 330 (FIG. 1) provided on the plate-like body supporting units 100, 200, 300, and the incident state of reflected light to the reflection sensor provided in the plate-like body detection unit 400, and displays the judgment result.

[0077] Fig. 7 is an explanatory diagram showing examples of images IMa and IMb captured by the camera 710a (Fig. 6). Fig. 7(a) shows an image IMa captured when the parts to be attached 810, 820, and 830 are properly attached to the proper plate-like body 900a as shown in Fig. 6, and Fig. 7(b) shows an image IMb captured when the parts to be attached are attached to an inappropriate plate-like body.

[0078] As shown in Fig. 7(a), an image IMa captured when the parts 810, 820, and 830 are properly assembled to the proper plate-like body 900a (Fig. 6) includes an image IP1a representing the plate-like body 900a. An image IP2a corresponding to the product number label 951a attached to the plate-like body 900a (plate-like member 950a) is included inside the image IP1a.

[0079] Computer 720a (FIG. 6) analyzes image IMa captured in this way and recognizes the plate-shaped object's product number "123-456" from image IP2a of product number sticker 951a. The recognized product number "123-456" is then compared with the product number "123-456" of proper plate-shaped object 900a. Since these product numbers are the same, the plate-shaped object is determined to be proper, and the determination result is sent to determination display unit 500a.

[0080] In the example of Figure 6, the mounting parts 810, 820, and 830 are properly assembled to the plate-like body 900a, so the on / off states of the limit switches 130, 230, and 330 (Figure 1) of the plate-like body support parts 100, 200, and 300 and the incident state of reflected light to the reflective sensor of the plate-like body detection part 400 are in states (on state and incident state) that indicate that the mounting parts 810, 820, and 830 are properly assembled.

[0081] Then, the judgment display unit 500a judges that the assembly parts 810, 820, 830 have been properly assembled to the proper plate body 900a based on the on / off state (on state) of the limit switches 130, 230, 330, the incident state (incident state) of the reflected light to the reflective sensor of the plate body detection unit 400, and the product number judgment result in the computer 720a, and turns on the LED lamp 502.

[0082] On the other hand, as shown in FIG. 7(b), image IMb captured when assembly parts 810, 820, and 830 (FIG. 6) are assembled to an improper plate-like body includes image IM1b of a plate-like body with a different shape, including image IP2b of a product number sticker with product number "123-789" written on it, which is different from the product number on the correct plate-like body 900a.

[0083] Therefore, computer 720a (Figure 6) determines that the product number "123-789" recognized from image IP2b of the product number sticker is not the appropriate product number "123-456" of plate-like body 900a, and sends the determination result that the plate-like body is inappropriate to determination display unit 500a.

[0084] Then, the judgment display unit 500a judges that the assembly of the parts 810, 820, 830 to be attached is proper based on the on / off state (on state) of the limit switches 130, 230, 330 and the incident state (incident state) of the reflected light to the reflective sensor of the plate-shaped body detection unit 400, but judges that the parts 810, 820, 830 to be attached are not properly assembled to the proper plate-shaped body 900a based on the judgment result of the computer 720a that the plate-shaped body is improper, and keeps the LED lamp 502 in an off state.

[0085] In this way, according to the second embodiment, if the plate-shaped body to which the assembly parts 810, 820, and 830 are to be assembled is inappropriate, it is possible to know that the assembly is inappropriate even if all of the assembly parts 810, 820, and 830 are assembled. Therefore, even if an inappropriate plate-shaped body is mistakenly mixed in, it is possible to prevent the inappropriate plate-shaped body from being judged as appropriate and sent to the next process.

[0086] In the above explanation using Fig. 7, the part number on the part number sticker attached to the plate is recognized and the recognized part number is compared with the appropriate part number, but the shape of the plate may be compared with the shape of the appropriate plate 900a (Fig. 6). Furthermore, in addition to the part number and shape of the plate, defects such as scratches and chips on the plate may be detected, and defective plates may not be used. In this way, the occurrence of non-conforming products due to the plate can be suppressed at the stage of assembling the assembly parts to the plate.

[0087] Furthermore, in the second embodiment, image analysis is performed in the computer 720a, but it is also possible to realize the image analysis function of the computer 720a in a camera and omit the computer 720a.

[0088] C. Variations: The present invention is not limited to the above-described embodiments, and can be embodied in various forms without departing from the spirit and scope of the present invention. For example, the following modifications are also possible.

[0089] C1. Variation 1: In the above embodiment, the bolts 811, 821, 831 passing through the washers 812, 822, 823 are attached as the attachment parts 810, 820, 830 so as to penetrate the plate-like bodies 900, 900a, but the present invention can be applied to various parts as long as they are parts that can be attached so as to penetrate the plate-like body. For example, the present invention can also be applied to cases where a fastening part such as a bolt alone, a rivet, or a push-in fastener, or a sensor head of various sensors is attached to a plate-like body as an attachment part.

[0090] C2. Variation 2: In each of the above embodiments, three parts to be attached 810, 820, 830 are attached to the plate-like bodies 900, 900a, but the number of parts to be attached to the plate-like body may be any number equal to or greater than 2. In this case, the part assembling jig is provided with the same number of plate-like body support parts as the number of parts to be attached.

[0091] C3. Variation 3: In each of the above embodiments, the plate-like members 950, 950a (FIG. 2) constituting the plate-like bodies 900, 900a are curved in the Y direction, but the plate-like members may be flat or curved in a different manner.

[0092] Furthermore, the plate-like members 950, 950a have regions in which the through holes 959, 958, 957 to which the rubber bushings 910, 920, 930 are attached are provided that are substantially parallel to one another. Therefore, the mounting members 810, 820, 830 are assembled so as to penetrate downward (toward the lower surface) of the plate-like members 950, 950a (plate-like bodies 900, 900a), but generally, the mounting members are assembled so as to penetrate toward one surface of the plate-like body.

[0093] C4. Variation 4: In the above-described embodiments, the plate-like body 900, 900a to which the assembly parts are to be attached is composed of the plate-like member 950, 950a and the rubber bushing 910, 920, 930. However, the plate-like body may take various forms as long as it is plate-like, has a plurality of protruding parts protruding in one surface direction, and the assembly parts can be inserted in the surface direction at the positions of the protruding parts. However, the plate-like body can take various forms as long as it is plate-shaped, has a plurality of protruding portions protruding in one surface direction, and it is possible to pass the mounting parts through the protruding portions in the surface direction at the positions of the protruding portions.

[0094] The present invention can be applied to a plate-like body having various members attached thereto, each of which has a hole through which an assembly part passes, such as a bush made of a material other than rubber instead of a rubber bush, or a collar made of metal or resin, etc. The present invention can also be applied to a plate-like body made of a single plate material that is molded so as to protrude in the direction of one surface at a position through which an assembly part passes.

[0095] C5. Variation 5: In the above-mentioned embodiments, the structural part of the plate-shaped body support part 100, 200, 300 is composed of the abutment part 120, 220, 320 and the base part 110, 210, 310, but the structure of the structural part of the plate-shaped body support part may be changed in various ways. For example, the parts corresponding to the abutment part and the base part may be integrated. In general, the plate-shaped body support part may be provided with a hollow part for accommodating the protruding part of the plate-shaped body, and may be configured so that the open end face of the hollow part abuts against the plate-shaped body. When the structure of the plate-shaped body support part is changed, the manner of mounting the plate-shaped body support part to the base plate 11, the method of wiring, etc. may be changed as appropriate.

[0096] In addition, in each of the above embodiments, the structural part of the plate-like object detection unit 400 is composed of the base part 410 and the sensor part 420, but the structure of the structural part of the plate-like object detection unit may be modified in various ways. For example, it is possible to integrate the parts corresponding to the sensor part and the base part. When the structure of the structural part of the plate-like object detection unit is modified, the manner in which the plate-like object detection unit is attached to the base plate 11, the method of routing the wiring, etc. are appropriately modified.

[0097] C6. Variation 6: In the above embodiments, the limit switches 130, 230, 330 detect that the parts to be attached 810, 820, 830 have been attached to the plate-like body support parts 100, 200, 300, but other means can also be used to detect that the parts to be attached 810, 820, 830 have been attached. For example, an inductive or capacitive proximity sensor can be disposed at the bottom of the opening, and the tip of the part to be attached 810, 820, 830 can be detected by the proximity sensor. Also, a transmission type photoelectric sensor can be used to detect the tip of the part to be attached 810, 820, 830.

[0098] C7. Variation 7: In each of the above embodiments, the plate-shaped body detection unit 400 detects that the plate-shaped body 900, 900a has been attached to the component assembly jig 10 using a reflective photoelectric sensor, but the attachment of the plate-shaped body 900, 900a can also be detected by other means. For example, a limit switch can be disposed at the upper end of the plate-shaped body detection unit, and the plunger of the limit switch can be detected to be pushed down by the plate-shaped body 900, 900a (plate-shaped member 950, 950a). Also, an inductive or capacitive proximity sensor can be disposed at the upper end of the plate-shaped body detection unit, and the plate-shaped body 900, 900a (plate-shaped member 950, 950a) can be detected by the proximity sensor.

[0099] C8. Variation 8: In each of the above embodiments, the judgment display unit 500, 500a judges whether or not the parts 810, 820, 830 to be attached have been properly attached to the plate body support parts 100, 200, 300 based on the on / off state of the limit switches 130, 230, 330 provided on the plate body support parts 100, 200, 300 and the state of incidence of reflected light to the reflection sensor provided on the plate body detection unit 400. However, it is also possible to omit the plate body detection unit 400 and judge whether or not the parts 810, 820, 830 to be attached have been properly attached to the plate body support parts 100, 200, 300 based only on the on / off state of the limit switches 130, 230, 330.

[0100] However, by appropriately setting the shape and arrangement of the plate-shaped object detection unit, it is possible to prevent an improper plate-shaped object having a different shape from a proper plate-shaped object from being attached to the part assembly jig, or to prevent an improper plate-shaped object from being detected when attached to the part assembly jig. Therefore, even if an improper plate-shaped object is mistakenly mixed in, it is possible to prevent the improper plate-shaped object from being judged as proper and sent to the next process.

[0101] C9. Variation 9: In each of the above embodiments, a microcomputer is provided in the judgment display unit 500, 500a, and the microcomputer judges whether the parts 810, 820, 830 to be assembled on the plate-like bodies 900, 900a have been properly assembled, and controls the lighting state of the LED lamps 140, 240, 340, 502. However, it is also possible to judge the assembly state and control the lighting state using wired logic that is an appropriate combination of logic circuits. However, it is preferable to use a microcomputer, since it is easier to handle a process of handling a wide variety of plate-like bodies in small quantities and to handle design changes of the plate-like bodies, etc.

[0102] C10. Variation 10: In each of the above embodiments, the plate-like body support units 100, 200, 300, the plate-like body detection unit 400, and the judgment display units 500, 500a are attached to the base plate 11, but the base plate 11 on which these units 100, 200, 300, 400, 500, 500a are attached may be omitted. In this case, the units 100, 200, 300, 400, 500, 500a are directly attached to a workbench or the like.

[0103] However, when handling multiple types of plate-shaped bodies, it is preferable to use the base plate 11 as in the above embodiments, since it is easier to prepare a separate part assembly jig for each type of plate-shaped body. Also, as in the first embodiment, by mounting the battery box 600 on the base plate 11 and driving the judgment display unit 500 with power supplied from the battery box 600, it is possible to determine whether or not the parts 810, 820, 830 to be assembled on the plate-shaped body 900 have been properly assembled using only the plate-shaped body assembly jig 10. Therefore, when the assembly work is entrusted to an outsourced company or a home-based company, the quality of the assembled delivered goods can be improved. [Explanation of symbols]
