[0011] An inspection device 50 and an inspection system 1 according to an embodiment of the present disclosure will be described below with reference to FIGS.
[0012] (Inspection System) Inspection system 1 (see Figs. 1 and 2) inspects, for example, the adhesion of a seal applied when repairing an aircraft wing. Hereinafter, the wing to be inspected will be referred to as object 2. As shown in Fig. 3, object 2 includes an outer panel 3 and a stringer 4.
[0013] The skin 3 forms the outer shell of the wing of an aircraft. The skin 3 is formed, for example, in a flat plate shape. The stringer 4 is attached to the skin 3. The stringer 4 includes a connection portion 4a that connects to the skin 3, and a protrusion portion 4b that separates the stringer 4 from the skin 3. The connection portion 4a is located on the side closer to the skin 3 than the protrusion portion 4b. The protrusion portion 4b is located on the side farther away from the skin 3 than the connection portion 4a.
[0014] A hollow portion (hereinafter referred to as a narrow portion 4c) is formed between the protrusion 4b and the outer plate 3. The stringer 4 is, for example, a hat-shaped hat stringer. The outer plate 3 and the stringer 4 are made of a composite material such as glass fiber reinforced plastics (GFRP) or carbon fiber reinforced plastics (CFRP).
[0015] 1 and 2 is used for inspecting the seal of a narrow portion 4c between a protrusion 4b and an outer plate 3. The inspection system 1 inspects the seal on the surface of a stringer 4 within the narrow portion 4c.
[0016] The inspection system 1 includes an inspection device 50, an automation device 10, a pipe 6, and a connecting member 20. The inspection device 50 is inserted into the narrow portion 4c and is sent to a seal inspection position by the automation device 10, which will be described later. A detailed configuration of the inspection device 50 will be described later.
[0017] In the following, the three mutually intersecting directions are referred to as a first direction D1, a second direction D2, and a third direction D3. In this embodiment, the first direction D1, the second direction D2, and the third direction D3 are mutually orthogonal, and the first direction D1 is orthogonal to the horizontal plane, and the second direction D2 and the third direction D3 are along the horizontal plane. Note that the first direction D1 may be slightly inclined with respect to the horizontal plane, and the second direction D2 and the third direction D3 may slightly intersect the horizontal plane. In the following, the first direction D1 may be referred to as the up-down direction, the second direction D2 as the front-rear direction, and the third direction D3 as the left-right direction.
[0018] (automated equipment) The automation device 10 automatically moves the inspection device 50 in the second direction D2. The automation device 10 includes a cart 11, a jack 12, and an automation device main body 13.
[0019] (Trolley) The dolly 11 moves the jack 12 and the automation device main body 13. The dolly 11 includes a body 11a, casters 11b, and a handle 11c. The body 11a is disposed at a position slightly above the floor surface and extends horizontally. The body 11a is formed in a rectangular shape extending in a second direction D2 (front-rear direction) when viewed in a first direction D1 (up-down direction).
[0020] When viewed in the first direction D1, casters 11b are provided at the four corners of the body 11a. The casters 11b are attached to the underside of the body 11a. Each caster 11b is provided so as to be able to roll on the floor surface. The four casters 11b support the body 11a from below. The handle 11c is provided at an end of the body 11a on one side in the second direction D2 (the rear side in the front-rear direction). The handle 11c extends upward from the body 11a. An operator moves the cart 11 by gripping the handle 11c.
[0021] (jack) The jack 12 is placed on the body 11a of the cart 11. The automation device main body 13 is placed on the jack 12. The jack 12 is provided so as to be extendable and retractable in a first direction D1. The position of the automation device main body 13 in the first direction D1 is adjusted by the jack 12 extending and retracting in the first direction D1.
[0022] (Automated equipment body) The automation device main body 13 includes a base plate 14 , a moving mechanism 15 , and a clamping mechanism 16 . The substrate 14 rests on the jack 12 .
[0023] (Moving mechanism) The moving mechanism 15 is placed on the substrate 14. A pipe 6 connected to the inspection device 50 is connected to the moving mechanism 15. The pipe 6 extends in the second direction D2. The moving mechanism 15 holds the end of the pipe 6 on the opposite side to the inspection device 50 in the second direction D2, and moves the pipe 6 in the second direction D2. The moving mechanism 15 is, for example, an electric actuator, and has a base 15a and an operating unit 15b. The base 15a extends in the second direction D2. The operating unit 15b is attached to the base 15a. One end of the pipe 6 in the second direction D2 is fixed to the operating unit 15b. The operating unit 15b moves on the base 15a in the second direction D2. When the operating unit 15b moves in the second direction D2, the pipe 6 moves in the second direction D2, and the inspection device 50 connected to the pipe 6 also moves in the second direction D2 in conjunction with the pipe 6.
[0024] (Clamp mechanism) The clamp mechanism 16 is provided at an end of the substrate 14 on the other side in the second direction D2 (front side in the front-rear direction). A pair of clamp mechanisms 16 are provided sandwiching the moving mechanism 15 in the third direction D3 (left-right direction). The clamp mechanism 16 has a leg 16a standing upward from the substrate 14, and a gripper 16b provided at the upper end of the leg 16a. The leg 16a supports the gripper 16b from below. The gripper 16b holds the object 2 from both sides in the first direction D1 (up-down direction). This prevents the object 2 from shifting in position in the horizontal direction. The two clamping mechanisms 16 may be arranged offset in the second direction D2. By arranging them in this manner, the automated device 10 can be used even if the end of the object 2 on the clamping mechanism 16 side is inclined with respect to the third direction D3.
[0025] (pipe) The pipe 6 extends in the second direction D2 from the operating unit 15b of the moving mechanism 15 towards the inspection device 50. The pipe 6 is connected to the inspection device 50 from the second direction D2. The pipe 6 transmits power to move the inspection device 50, which is disposed in the narrow portion 4c between the outer plate 3 and the stringer 4, in the second direction D2 (front-rear direction). In the illustrated example, one pipe 6 is provided on one side in the second direction D2 (rear side in the front-rear direction) of the inspection device 50, and the automation device 10 is installed on one side in the second direction D2 of this pipe 6 (rear side in the front-rear direction). The length L1 of the pipe 6 in the first direction D1 is designed to be, for example, 1.5 m or more and 2.5 m or less, and the outer diameter R1 of the pipe 6 is designed to be, for example, 20 mm or more and 25 mm or less.
[0026] (Connecting parts) The connecting member 20 connects the pipe 6 to a connecting pipe 91 extending from the inspection device 50 in the second direction D2. The connecting member 20 has a central shaft portion 21, a male thread portion 22, and a flange portion 23.
[0027] (center shaft part) The central shaft portion 21 extends in the second direction D2. One end of the central shaft portion 21 in the second direction D2 is inserted into either the pipe 6 or the connecting pipe 91. The other end of the central shaft portion 21 in the second direction D2 is inserted into the other of the pipe 6 or the connecting pipe 91. In the illustrated example, the rear end of the central shaft portion 21 is inserted into the pipe 6, and the front end of the central shaft portion 21 is inserted into the connecting pipe 91.
[0028] (Male thread) The male thread portion 22 is provided at both ends of the central shaft portion 21 in the second direction D2. The male thread portion 22 is designed to be able to screw into the inner circumferential surfaces of the pipe 6 and the connecting pipe 91. The outer diameter of the male thread portion 22 is formed to be slightly larger than the inner diameter of the pipe 6 and the connecting pipe 91. This allows the connecting member 20 to be firmly connected to the pipe 6 and the connecting pipe 91.
[0029] (Flange) The flange 23 protrudes radially outward from the outer circumferential surface at the center of the central shaft portion 21 in the second direction D2 beyond the pipe 6 and the connecting pipe 91. The flange 23 is formed of a material (such as resin) having a lower hardness than the inspected surface 5. The flange 23 prevents the pipe 6 and the connecting pipe 91 from contacting the inner surface (such as the inspected surface 5) of the narrow portion 4c of the object 2 composed of the outer plate 3 and the stringer 4. Note that instead of the flange 23, the pipe 6 and the connecting pipe 91 may be wrapped with a material having a low hardness, such as a film or rubber. Such a measure can also prevent the pipe 6 and the connecting pipe 91 from contacting the inner surface of the narrow portion 4c and causing scratches.
[0030] (Inspection equipment configuration) The inspection device 50 is disposed in the narrow portion 4c of the object 2. (In the illustrated example, the inspection device 50 is inserted into the narrow portion 4c from one side in the second direction D2 (the rear side in the front-to-rear direction).) The inspection device 50 performs a seal inspection of the inspected surface 5 on which a seal has been applied within this narrow portion 4c.
[0031] 5, in this embodiment, the seal inspection is performed with the target object 2 disposed so that the outer plate 3 is located below the stringer 4. Hereinafter, the surface of the outer plate 3 that is subjected to the seal inspection is referred to as the inspected surface 5.
[0032] A joint 5a that smoothly joins the outer plate 3 and the stringer 4 is provided within the narrow portion 4c. This joint 5a extends in the third direction D3 on the inspection surface 5 and is formed so as to become gradually thinner in the third direction D3 from the connection portion 4a of the stringer 4 toward the inside of the narrow portion 4c. The boundary between the joint 5a and the inspection surface 5 (hereinafter referred to as edge 5b) slightly protrudes from the inspection surface 5. The seal portion 8 is formed so as to cover this edge 5b.
[0033] The seal portion 8 of this embodiment has a brush coat 8a and an edge seal 8b. The brush coat 8a is a seal portion 8 formed in a flat shape by applying a seal material to the surface 5 to be inspected by a brush (not shown). The brush coat 8a is formed on the upper surface of the joint portion 5a. The brush coat 8a extends in the third direction D3 and covers the edge 5b. The edge seal 8b is a seal portion 8 formed on the brush coat 8a at a position overlapping the edge 5b in the first direction D1. The edge seal 8b is formed thicker in the first direction D1 than the brush coat 8a. The inspection device 50 can inspect the adhesion of the brush coat 8a to the surface 5 to be inspected by applying a pressing force in the second direction D2 to the boundary portion 8c of the brush coat 8a with the surface 5 to be inspected. The inspection device 50 can also inspect the adhesion of the edge seal 8b to the brush coat 8a by applying a pressing force in the second direction D2 to the boundary portion 8d of the edge seal 8b with the brush coat 8a.
[0034] As shown in FIGS. 6 and 7, the inspection device 50 includes an inspection unit 50a and an inspection device base unit 50b arranged next to the inspection unit 50a on one side in the second direction D2 (rear side in the front-rear direction).
[0035] (Inspection Department) The inspection unit 50 a includes a base 51 , a contact unit 52 , a biasing device 60 , a stopper 53 , a sensor unit 54 , and a retraction mechanism 57 .
[0036] (base) The base 51 is disposed facing the inspection surface 5 in the first direction D1 (up-down direction). The base 51 extends in the second direction D2 (front-rear direction). The base 51 is provided with a through hole 51a penetrating in the first direction D1. The upper surface of the base 51 is provided with a pair of mounting portions 51b facing each other in the third direction D3 (left-right direction) with the through hole 51a in between. The base 51 is also attached to a bracket 67, which will be described later. The base 51 is provided so that the mounting position can be adjusted in the third direction D3.
[0037] (Contact part) The contact portion 52 is mounted on the base 51 via a biasing device 60, which will be described later. The contact portion 52 contacts the seal portion 8 on the surface to be inspected 5 from one side in a second direction D2 intersecting the first direction D1 (the rear side in the front-to-rear direction). The contact portion 52 is formed of an elastic material such as rubber. The contact portion 52 protrudes toward the surface to be inspected 5 in the first direction D1. A tip portion 52a of the contact portion 52 on the surface to be inspected 5 side is formed in a spherical shape. The inspection device 50 inspects the adhesion of the seal portion 8 by pressing the contact portion 52 against the seal portion 8 from one side to the other side in the second direction D2 (from the rear side to the front side in the front-to-rear direction).
[0038] (energizing device) The biasing device 60 is mounted on the base 51. The biasing device 60 biases the contact portion 52 with a force in a direction from one side to the other side in the second direction D2. As shown in FIG. 8, the biasing device 60 has a rotating shaft portion 61, an arm 62, and a biasing member 63.
[0039] (Rotating shaft) The rotating shaft portion 61 is provided on the opposite side in the second direction D2 to the contact portion 52 during inspection in the first direction D1 with respect to the base portion 51 as a reference, and extends in a third direction D3.
[0040] (arm) The arm 62 is attached to the rotating shaft portion 61 and is rotatable around the rotating shaft portion 61. The arm 62 extends on both sides in the second direction D2 with respect to the rotating shaft portion 61. A contact portion 52 is provided at one end of the arm 62 on one side in the second direction D2, and a biasing member 63, which will be described later, is provided at the other end of the arm 62 on the second direction D2.
[0041] The arm 62 of this embodiment is formed in an L-shape when viewed in the third direction D3. The arm 62 has an arm first portion 62a, an arm second portion 62b, and an arm curved portion 62c. The arm first portion 62a is attached to the rotating shaft portion 61 and extends in one direction along the second direction D2. The arm second portion 62b is provided on one side of the arm first portion 62a in the second direction D2 and extends in one direction along the first direction D1 toward the inspected surface 5. The arm second portion 62b is inserted into the through hole 51a of the base portion 51. The arm curved portion 62c connects the arm first portion 62a and the arm second portion 62b. The angle between the arm first portion 62a and the arm second portion 62b is slightly smaller than 90 degrees. The contact portion 52 is attached to the end of the arm second portion 62b on the contacted surface side. Moreover, the biasing member 63 is attached to the end portion on the other side in the second direction D2 of the arm first portion 62a.
[0042] (urging member) The biasing member 63 biases the arm 62 with a force such that the contact portion 52 moves from one side to the other side in the second direction D2 (from the rear side to the front side in the front-rear direction).
[0043] The biasing member 63 in this embodiment is a spring coil that expands and contracts in the first direction D1, and biases a spring force to the contact portion 52 via the arm 62. The biasing force (spring force) of the biasing member 63 is set to a value close to the force applied by hand (for example, a value of about 10 N to 15 N).
[0044] The biasing member 63 extends in the first direction (vertical direction) and connects the base 51 located below and the arm first portion 62a located above. The biasing member 63 biases the arm first portion 62a with a force from the other side in the second direction D2 toward one side (from the front side to the rear side in the front-rear direction). This allows the arm 62 to rotate around the rotation shaft portion 61, and the arm second portion 62b to bias the contact portion 52 with a force from the one side in the second direction D2 toward the other side (from the rear side to the front side in the front-rear direction).
[0045] The above-described biasing device 60 allows the contact portion 52 to rotate around the rotation shaft portion 61. An end point P of the contact portion 52 that is the furthest from the arm second portion 62b describes an arc-shaped locus C with the rotation shaft portion 61 as its center.
[0046] (Stopper) The stopper 53 is mounted on the base 51. The stopper 53 contacts an end (arm second part 62b) on one side in the second direction D2 (rear side in the front-to-rear direction) of the arm 62 from the other side in the second direction D2 (front side in the front-to-rear direction).
[0047] (Sensor section) The sensor unit 54 is mounted on the base 51. The sensor unit 54 is provided at an end of the through-hole 51a on one side in the second direction D2 (rear side in the front-to-rear direction) when viewed in the first direction D1 (up-down direction). The sensor unit 54 is installed so as to face the contact portion 52 side in the second direction D2. The sensor unit 54 detects the position of the contact portion 52. The sensor unit 54 in this embodiment is a camera that photographs the contact portion 52 and the vicinity of the contact portion 52 (seal portion 8, etc.) from one side in the second direction D2 (rear side in the front-to-rear direction).
[0048] (Evacuation mechanism) The retraction mechanism 57 is mounted on the base 51. The retraction mechanism 57 contacts an end (arm second part 62b) of the arm 62 on one side in the second direction D2 (rear side in the front-rear direction) from the other side in the second direction D2 (front side in the front-rear direction). The retraction mechanism 57 has a retraction mechanism base part 57a and an expandable part 57b extending in the second direction D2 from the retraction mechanism base part 57a. The expandable part 57b is provided so as to be expandable in the second direction D2. When extended, the expandable part 57b applies a force to the arm 62 in a direction from the other side to one side in the second direction D2 (from the front side to the rear side in the front-rear direction). The retraction mechanism 57 is an air cylinder in which the expandable part 57b expands and contracts in the second direction D2 using air as a working fluid. The retraction mechanism 57 may be a hydraulic cylinder.
[0049] (Inspection device base) The inspection device base portion 50b includes a casing 55, a moving mechanism 65, a centering mechanism 70, and a brake mechanism 80.
[0050] (Casing) The casing 55 extends in the second direction D2. The casing 55 is formed in a box shape having an opening 55a that opens in the first direction D1. In this embodiment, the casing 55 is formed in a cube shape extending in the second direction D2. An outlet hole 55b that penetrates the casing 55 in the second direction D2 is formed at the end of the casing 55 on the other side in the second direction D2 (front side in the front-rear direction). As shown in FIG. 9, a buffer member 55c is provided on the surface of the casing 55 opposite the opening 55a in the first direction D1 (the lower surface on the side of the surface 5 to be inspected). A pair of the buffer members 55c are provided so as to face each other in the third direction D3. Each of the buffer members 55c is formed in a straight line extending in the second direction D2. It is preferable that the buffer member 55c is made of a material that is slidable on the surface 5 to be inspected and has a lower hardness than the surface 5 to be inspected.
[0051] (Advancing / retracting mechanism) The advancing / retreating mechanism 65 is provided at an end of the base 51 on one side in the second direction D2 (rear side in the front-rear direction). The advancing / retreating mechanism 65 has a first actuator 66 and a bracket 67. The first actuator 66 is housed in the casing 55 and disposed near the drawing hole 55b. The bracket 67 is attached to the first actuator 66. The bracket 67 is formed in an L-shape when viewed in the first direction D1 (viewed in the up-down direction). The bracket 67 has a bracket first part 67a and a bracket second part 67b. The bracket first part 67a is disposed next to the first actuator 66 in the third direction D3 (left-right direction) and extends linearly in the second direction D2. The bracket first part 67a is drawn out to the outside of the casing 55 through the drawing hole 55b. The bracket first part 67a can be moved in the second direction D2 by the first actuator 66. The bracket second part 67b is provided at an end part on the other side in the second direction D2 (front side in the front-rear direction) of the bracket first part 67a, and extends in the third direction D3 from the bracket first part 67a. The bracket second part 67b is disposed on the other side in the second direction D2 of the first actuator 66. The base part 51 of the inspection part 50a is attached to the bracket second part 67b.
[0052] When the first actuator 66 is actuated, the bracket 67 moves in the second direction D2, and the base 51 also moves in the second direction D2 together with the bracket 67. In this manner, the advancing / retreating mechanism 65 can move the base 51 in the second direction D2. Note that the force of the advancing / retreating mechanism 65 that moves the base 51 in the second direction D2 is set to a value greater than the set value of the reaction force that the contact portion 52 receives from the seal portion 8.
[0053] (Centering mechanism) The centering mechanism 70 is disposed at a fixed position in the third direction D3 (left-right direction) with respect to the contact portion 52. The centering mechanism 70 positions the contact portion 52 in the third direction D3. The centering mechanism 70 is disposed on the advancing / retracting mechanism 65. Two centering mechanisms 70 are provided side by side in the second direction D2 (front-rear direction). The centering mechanism 70 protrudes from the opening 55a of the casing 55 in the first direction D1. The centering mechanism 70 has a second actuator 71 and a centering block 72.
[0054] As shown in FIG. 9, the second actuator 71 is placed on the first actuator 66 . The centering block 72 is placed on the second actuator 71 and is located above the opening 55a of the casing 55. A pair of centering blocks 72 are provided facing each other in the third direction D3. Each of the centering blocks 72 is movable in the third direction D3. In this embodiment, the pair of centering blocks 72 facing each other in the third direction D3 are linked by the second actuator 71 and move toward and away from each other in the third direction D3.
[0055] The side surface of the centering block 72 facing outward in the third direction D3 is an inclined surface 72a that is inclined along the shape of the side wall surface 4c1 of the narrow portion 4c that faces the centering block 72 in the third direction D3. The centering block 72 moves outward in the third direction D3, and the inclined surface 72a is pressed against the side wall surface 4c1, thereby positioning the inspection device 50 in the third direction D3. In addition, to prevent scratches inside the narrow portion 4c, the centering block 72 is made of a material that is lower in hardness than the target object 2, which is the product.
[0056] (Brake mechanism) The brake mechanism 80 is disposed at a fixed position in the first direction D1 (up-down direction) and the third direction D3 (left-right direction) relative to the contact portion 52, and prevents misalignment in the second direction D2 (front-rear direction). The brake mechanism 80 is housed in the casing 55, and disposed on one side in the second direction D2 (rear side in the front-rear direction) of the advancing / retreating mechanism 65 and the centering mechanism 70. As shown in FIG. 10, two brake mechanisms 80 are provided side by side in the third direction D3. Each brake mechanism 80 is designed to extend in the second direction D2. The brake mechanism 80 has a third actuator 81 and a brake block 82.
[0057] The third actuator 81 is placed on the bottom surface of the casing 55 . The brake block 82 is placed on the third actuator 81 and is located above the opening 55a of the casing 55. The brake block 82 is movable by the third actuator 81 in a direction intersecting the second direction D2 (the first direction D1 in this embodiment). The brake block 82 is pressed by the third actuator 81 against an upper wall surface 4c2 (the inner surface of the narrow portion 4c facing the surface to be inspected 5 and the first direction D1) in the narrow portion 4c in the first direction D1. This fixes the inspection device 50 in the second direction D2, and prevents positional deviation in the second direction D2. In addition, the brake block 82 is desirably formed of a material that is lower in hardness than the target object 2, which is a product, such as urethane, and that can exert a high gripping force.
[0058] (Pipe attachment part) The pipe 6 is attached to the pipe attachment portion 50c via the above-mentioned connecting member 20. The pipe attachment portion 50c is provided on one side in the second direction D2 (the rear side in the front-to-rear direction) of the casing 55. The pipe attachment portion 50c has a connection portion 90 and a connecting pipe 91. The connection portion 90 is connected to the casing 55. The connection portion 90 extends to one side in the second direction D2 from a side surface of the casing 55 facing one side in the second direction D2.
[0059] (Connecting pipe) The connecting pipes 91 are arranged side by side on one side in the second direction D2 (rear side in the front-to-rear direction) with respect to the casing 55. The connecting pipes 91 extend from one end of the connecting portion 90 on one side in the second direction D2 to one side in the second direction D2. The connecting pipes 91 are connected to the pipes 6 via the connecting member 20 described above.
[0060] (controller) The controller 7 is wired to the inspection device 50 via a cable (not shown). The controller 7 may be wirelessly connected to the inspection device 50. For example, an operator can operate the advance / retreat mechanism 65, the centering mechanism 70, and the brake mechanism 80 of the inspection device 50 by operating the controller 7.
[0061] (Testing method procedure) The inspection method according to this embodiment will be described with reference to the flow in Fig. 11. Here, when a defect occurs in a narrow portion 4c between an outer plate 3 and a stringer 4 that constitute an object 2 (an aircraft wing), for example, a sealant is applied to repair the seal. The procedure for inspecting the adhesion of a seal portion 8 formed by this seal repair will be described below.
[0062] First, in a state where the object 2 is arranged so that the outer plate 3 is on the lower side and the stringer 4 is on the upper side, the automation device 10 is operated to insert the inspection device 50 into the narrow portion 4c from one side in the second direction D2 (the rear side in the front-rear direction) and install the inspection device 50 on the surface 5 to be inspected (step S1). In step S1, the retraction mechanism 57 is extended to push the arm 62 and retract the contact portion 52 upward. After step S1, the centering mechanism 70 is operated to move the centering block 72 in the third direction D3 (left-right direction) and press it against the side wall surface 4c1 of the narrow portion 4c, thereby positioning the contact portion 52 in the third direction D3 (step S2). By step S2, the contact portion 52 is placed in the same position in the third direction D3 as the seal portion 8.
[0063] After step S2, the brake mechanism 80 is operated to press the brake block 82 against the upper wall surface 4c2 of the inner surface of the narrow portion 4c that faces the inspected surface 5, thereby fixing the inspection device 50 (step S3). In step S3, the brake mechanism 80 functions as a tension rod.
[0064] After step S3, the advancing / retracting mechanism 65 is operated to press the contact portion 52 and inspect the seal portion 8 (step S4). In step S4, the advancing / retracting mechanism 65 moves the inspection portion 50a from one side to the other side in the second direction D2 (from the rear side to the front side in the front-rear direction). Then, as shown in Fig. 10, the end point P of the contact portion 52 is pressed against the boundary portion 8c of the seal portion 8 with the inspected surface 5. If the seal portion 8 does not peel off, it can be determined that sufficient adhesion is ensured.
[0065] After step S4, the retraction mechanism 57 is extended to separate the contact portion 52 from the seal portion 8 (step S5). After step S5, the inspection device 50 may be removed, or the inspection device 50 may be moved to start inspection of another inspection point. Note that, to prevent the contact portion 52 from getting stuck, it is desirable to always extend the retraction mechanism 57 to retract the contact portion 52 while the inspection device 50 is moving. Through the above procedures, the inspection of the adhesion of the seal portion 8 is completed.
[0066] Here, the inspection method has been described taking as an example a case where the inspection device 50 presses the contact portion 52 against the boundary portion 8c of the seal portion 8 (brush coat 8a) with the inspected surface 5 to inspect the adhesion of the brush coat 8a, but is not limited to this. The inspection device 50 can also inspect the adhesion of the edge seal 8b by pressing the contact portion 52 against the boundary portion 8d of the edge seal 8b with the brush coat 8a.
[0067] (Action and effect) The inspection device 50 and the inspection system 1 of the present embodiment can achieve the following advantageous effects.
[0068] In this embodiment, the inspection device 50 comprises a base 51 arranged facing the sealed inspection surface 5 in a first direction D1, a contact portion 52 mounted on the base 51 and contacting the seal portion 8 of the inspection surface 5 from one side in a second direction D2 intersecting the first direction D1, a biasing device 60 mounted on the base 51 and applying a force to the contact portion 52 in a direction from one side to the other side of the second direction D2, and a forward / backward mechanism 65 provided at an end of the base 51 on one side of the second direction D2 for moving the base 51 in the second direction D2. The biasing device 60 has a rotating shaft portion 61 extending in a third direction D3 intersecting the first direction D1 and the second direction D2, an arm 62 that is rotatable around the rotating shaft portion 61, extends on both sides in the second direction D2 relative to the rotating shaft portion 61 and has a contact portion 52 provided at an end on one side of the second direction D2, and a biasing member 63 provided at an end on the other side of the second direction D2 of the arm 62 that biases a force on the arm 62 so that the contact portion 52 moves from one side of the second direction D2 to the other side.
[0069] The advance / retract mechanism 65 moves the base 51 from one side to the other side in the second direction D2, so that the contact portion 52 is pressed against the seal portion 8 in a direction from one side to the other side in the second direction D2. At this time, the contact portion 52 receives a force from the seal portion 8 in a direction from the other side to one side in the second direction D2, but the arm 62 rotates around the rotating shaft portion 61, so that the contact portion 52 moves to retreat upward from the seal portion 8. This allows the force received by the contact portion 52 from the seal portion 8 to be released. On the other hand, the biasing member 63 biases the arm 62 with a force so that the contact portion 52 moves from one side to the other side in the second direction D2, so that the contact portion 52 can be pressed against the seal portion 8 with a force equal to or greater than a certain value. Therefore, the contact portion 52 can be pressed against the seal portion 8 with a desired force while avoiding the application of a force equal to or greater than a set value to the contact portion 52 due to the rotation of the arm 62. This allows the contact portion 52 to be pressed with an appropriate force less than a set value against the boundary portion 8c of the brush coat 8a and the inspected surface 5. Also, the contact portion 52 can be pressed with an appropriate force less than a set value against the boundary portion 8d of the edge seal 8b and the brush coat 8a.
[0070] In this way, according to this embodiment, it is possible to automatically inspect the adhesion of the seal portion 8 while avoiding application of a force equal to or greater than a set value to the contact portion 52. Therefore, it is possible to safely automate the seal inspection.
[0071] In this embodiment, the inspection device 50 is mounted on a base 51, contacts the end of one side of the second direction D2 of the arm 62 from the other side of the second direction D2, and is extendable and contractible in the second direction D2.The inspection device 50 further includes a retraction mechanism 57 that applies a force to the arm 62 in a direction from the other side of the second direction D2 toward one side when extended.
[0072] For example, when the contact portion 52 receives an excessive reaction force from the seal portion 8, the retraction mechanism 57 extends and applies a force to the arm 62 in a direction from the other side to one side of the second direction D2. This allows the contact portion 52 to be completely retracted from the seal portion 8. This reliably prevents the contact portion 52 from being subjected to a force greater than a set value, further improving safety. Furthermore, since the contact portion 52 can be immediately separated from the seal portion 8 after the seal inspection, the next seal inspection can be started quickly.
[0073] In this embodiment, the inspection device 50 is mounted on the base 51 and further includes a sensor unit 54 that detects the position of the contact portion 52 .
[0074] As a result, even when the seal portion 8 cannot be seen with the naked eye, the contact portion 52 can be accurately pressed against the seal portion 8 to perform the seal inspection. This improves convenience and improves the accuracy of the seal inspection. In addition, in the case of this embodiment, it is possible to directly check whether the seal portion 8 is peeled off from outside the narrow portion 4c.
[0075] In this embodiment, the inspection device 50 further includes a centering mechanism 70 that is disposed at a position fixed in the third direction D3 with respect to the contact portion 52 and positions the contact portion 52 in the third direction D3. The centering mechanisms 70 are provided opposite each other in the third direction D3 and each have centering blocks 72 that are movable in the third direction D3.
[0076] For example, when there are wall surfaces on both sides of the inspection device 50 in the third direction D3, the centering mechanism 70 can be operated to press the pair of centering blocks 72 against the wall surfaces. At this time, by adjusting the position of each centering block 72 in the third direction D3, the position of the contact portion 52 in the third direction D3 can be adjusted so that the positions of the sensor portion 54 and the contact portion 52 in the third direction D3 coincide with each other. Therefore, the contact portion 52 can be accurately pressed against the seal portion 8, and the accuracy of the seal inspection can be further improved.
[0077] In this embodiment, the inspection device 50 further includes a brake mechanism 80 that is disposed at a fixed position in the first direction D1 and the third direction D3 with respect to the contact portion 52 and prevents positional deviation in the second direction D2. The brake mechanism 80 has a brake block 82 that is movable in a direction intersecting the second direction D2.
[0078] According to the above configuration, the brake mechanism 80 can be operated to press the brake block 82 against the upper wall surface 4c2. This makes it possible to suppress the inspection device 50 from shifting in the second direction D2 against the reaction force that the contact portion 52 receives from the seal portion 8. This makes it possible to prevent the contact portion 52 from shifting during the seal inspection, thereby preventing a decrease in the pressing force applied to the seal portion 8, thereby further improving the accuracy of the seal inspection.
[0079] In this embodiment, the inspection system 1 comprises an inspection device 50, a pipe 6 connected to the inspection device 50 from the second direction D2, and a moving mechanism 15 that grasps the end of the pipe 6 opposite the inspection device 50 in the second direction D2 and moves the pipe 6 in the second direction D2.
[0080] This makes it possible to automatically position the inspection device 50 in the second direction D2 with respect to the inspected surface 5. Therefore, in this embodiment, even the installation of the inspection device 50 can be performed automatically.
[0081] In this embodiment, the inspection device 50 further includes a connecting pipe 91 extending in the second direction D2. The inspection system 1 further includes a connecting member 20 connecting the pipe 6 and the connecting pipe 91. The connecting member 20 has a central shaft portion 21 extending in the second direction D2, one end in the second direction D2 being inserted into either the pipe 6 or the connecting pipe 91 and the other end in the second direction D2 being inserted into the other of the pipe 6 or the connecting pipe 91, male thread portions 22 provided at both ends of the central shaft portion 21 in the second direction D2 and capable of screwing into inner peripheral surfaces of the pipe 6 and the connecting pipe 91, and a flange portion 23 extending radially outward from the outer peripheral surface at the center of the central shaft portion 21 in the second direction D2 beyond the pipe 6 and the connecting pipe 91.
[0082] The connecting member 20 is firmly fixed to both the pipe 6 and the connecting pipe 91 of the inspection device 50 by the male thread portion 22. In addition, the flange portion 23 protrudes radially outward from the pipe 6 and the connecting pipe 91. This makes it possible to prevent the pipe 6 and the connecting pipe 91 from colliding with the surrounding inspected surface 5, etc. Furthermore, in this embodiment, the flange portion 23 is formed of a material that is lower in hardness than the inspected surface 5, so that even if the flange portion 23 comes into contact with the inspected surface 5, damage to the inspected surface 5 can be avoided.
[0083] In this embodiment, the length L1 of the pipe 6 in the first direction D1 is designed to be, for example, 1.5 m or more and 2.5 m or less, and the outer diameter R1 of the pipe 6 is designed to be, for example, 20 mm or more and 25 mm or less.
[0084] By designing the cross-sectional dimensions (length L1, outer diameter R1) of the pipe 6 in this way, the pipe 6 can obtain flexibility that allows it to follow the curved shape of the object 2 (in this embodiment, an aircraft wing) and robustness that does not buckle when pushed in the second direction D2. From the viewpoint of achieving both flexibility and robustness, it is most preferable that the length L1 of the pipe 6 is designed to be, for example, 2.0 m, and the outer diameter R1 of the pipe 6 is designed to be, for example, 22 mm. Furthermore, when the pipe 6 is connected to the inspection device 50, it is desirable that the second direction D2 from the pipe 6 to the inspection device 50 is, for example, 30 m or less. By doing so, even when the pipe 6 is connected to the inspection device 50, the pipe 6 is less likely to buckle when the inspection device 50 is pushed and pulled in the second direction D2.
[0085] In this embodiment, the base portion 51 is provided so that the attachment position can be adjusted in the third direction D3. This allows the mounting position of the inspection unit 50a to be shifted in the third direction D3, and the position of the contact unit 52 in the third direction D3 to be adjusted. Therefore, the adhesion of the edge seal 8b and the brush coat 8a provided on both sides in the third direction D3 can be inspected in the narrow portion 4c. When inspecting the adhesion of the edge seal 8b and the brush coat 8a on the opposite side in the third direction, the inspection unit 50a may be replaced with one having a structure symmetrical to the third direction D3. In addition, the contact unit 52 or the inspection unit 50a itself may be provided in a plurality of locations spaced apart from each other in the third direction D3, so that the adhesion of two or more seal portions 8 arranged in the third direction D3 can be inspected at once.
[0086] (Other embodiments) Although the embodiments of the present disclosure have been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and design changes and the like that do not depart from the gist of the present disclosure are also included. In the above embodiment, the inspection device 50 and the inspection system 1 are used to inspect the adhesion of the seal portion 8 in the narrow portion 4c, but the present invention is not limited to this. The inspection device 50 and the inspection system 1 may be used to inspect the adhesion of a seal portion applied to a portion other than the narrow portion 4c. Furthermore, the object 2 to be inspected by the inspection device 50 and the inspection system 1 is not limited to an aircraft wing, and the adhesion of seal portions applied to various devices can be inspected.
[0087] In the above embodiment, the case where the automated device 10 moves the inspection device 50 in the second direction D2 to install the inspection device 50 has been described, but this is not limited thereto. For example, an operator may grasp the pipe 6 extending from the inspection device 50 and manually move the inspection device 50 in the second direction D2 to install the inspection device 50. In the case of manual installation, by marking the pipe 6 or the mechanism that holds the pipe 6 (for example, the base 15a of the moving mechanism 15) with scales or marks, the brush 64 can be moved back and forth within an accurate operating range.
[0088] Also, although one pipe 6 is provided on one side in the second direction D2 (rear side in the front-to-rear direction) with respect to the inspection device 50, this is not limited thereto. Two pipes 6 may be provided, one on each side in the second direction D2 (front-to-rear direction) with respect to the inspection device 50. Also, instead of the pipe 6, two wires may be provided, one on each side in the second direction D2 (front-to-rear direction) with respect to the inspection device 50, and the inspection device 50 may be moved in the second direction D2 by pulling the two wires against each other in the second direction D2.
[0089] In the above embodiment, the biasing member 63 is a spring coil, but is not limited to this. For example, the biasing member 63 may be an air cylinder or the like.
[0090] In the above embodiment, the arm 62 is formed in an L-shape, but this is not limited thereto. The shape of the arm 62 can be changed as appropriate.
[0091] In the above embodiment, the brake block 82 is moved in the first direction D1 and pressed against the upper wall surface 4c2 of the narrow portion 4c, but the present invention is not limited to this. The brake block 82 may be moved in the third direction D3 and pressed against the side wall surface 4c1 of the narrow portion 4c.
[0092] In the above embodiment, the sensor unit 54 is a camera, but this is not limited to this. The method for detecting the contact portion 52 can be appropriately selected. The sensor unit 54 may detect the position of the contact portion 52 by irradiating a laser or a sound wave, for example.
[0093] <Additional Notes> The inspection device 50 and the inspection system 1 described in each embodiment can be understood, for example, as follows.
[0094] (1) An inspection device 50 according to a first aspect includes a base 51 arranged to face a sealed surface 5 to be inspected in a first direction D1, a contact portion 52 mounted on the base 51 and contacting a seal portion 8 of the surface 5 to be inspected from one side in a second direction D2 intersecting the first direction D1, a biasing device 60 mounted on the base 51 and biasing the contact portion 52 in a direction from one side to the other side in the second direction D2, and an advance / retract mechanism provided at an end of the base 51 on one side in the second direction D2 and moving the base 51 in the second direction D2. 65, and the biasing device 60 includes a rotating shaft portion 61 extending in a third direction D3 intersecting the first direction D1 and the second direction D2, an arm 62 that is rotatable around the rotating shaft portion 61, extends on both sides of the second direction D2 relative to the rotating shaft portion 61, and has the contact portion 52 provided at an end portion on one side of the second direction D2, and a biasing member 63 that is provided at an end portion of the arm 62 on the other side of the second direction D2 and biases a force on the arm 62 such that the contact portion 52 is directed from one side to the other side in the second direction D2.
[0095] The advance / retract mechanism 65 moves the base 51 from one side to the other side in the second direction D2, so that the contact portion 52 is pressed against the seal portion 8 in a direction from one side to the other side in the second direction D2. At this time, the contact portion 52 receives a force from the seal portion 8 in a direction from the other side to one side in the second direction D2, but the arm 62 rotates around the rotating shaft portion 61, so that the contact portion 52 moves to retreat from the seal portion 8. This allows the force received by the contact portion 52 from the seal portion 8 to be released. On the other hand, the biasing member 63 biases the arm 62 with a force so that the contact portion 52 moves from one side to the other side in the second direction D2, so that the contact portion 52 can be pressed against the seal portion 8 with a force equal to or greater than a certain value. Therefore, the contact portion 52 can be pressed against the seal portion 8 with a desired force while avoiding the application of a force equal to or greater than a set value to the contact portion 52 due to the rotation of the arm 62. This allows the contact portion 52 to be pressed with an appropriate force less than the set value against the boundary portion 8c of the seal portion 8 with the inspected surface 5. Furthermore, when the seal portion 8 is formed in a double layer, the contact portion 52 can be pressed with an appropriate force less than the set value against the boundary portion 8d between the seal portions 8.
[0096] (2) The inspection device 50 of the second aspect is the inspection device 50 of (1), and may further include a retraction mechanism 57 mounted on the base 51, contacting the end of the arm 62 on one side of the second direction D2 from the other side of the second direction D2, and adapted to be extendable and contractible in the second direction D2, which applies a force to the arm 62 in a direction from the other side of the second direction D2 toward one side when extended.
[0097] For example, when the contact portion 52 receives an excessive reaction force from the seal portion 8, the retraction mechanism 57 extends and applies a force to the arm 62 in a direction from the other side to one side of the second direction D2. This allows the contact portion 52 to be completely retracted from the seal portion 8. This reliably prevents the contact portion 52 from being subjected to a force greater than the set value.
[0098] (3) The inspection device 50 of a third aspect is the inspection device 50 of (1) or (2), and may further include a sensor unit 54 mounted on the base portion 51 and configured to detect the position of the contact portion 52.
[0099] This makes it possible to accurately press the contact portion 52 against the seal portion 8 and perform a seal inspection, even when the seal portion 8 cannot be seen with the naked eye.
[0100] (4) The inspection device 50 of a fourth aspect is any one of the inspection devices 50 of (1) to (3), and further includes a centering mechanism 70 that is arranged at a fixed position in the third direction D3 relative to the contact portion 52 and positions the contact portion 52 in the third direction D3, and the centering mechanism 70 may have centering blocks 72 arranged opposite the third direction D3 and each of which is movable in the third direction D3.
[0101] For example, when there are wall surfaces on both sides in the third direction D3 of the inspection device 50, the centering mechanism 70 can be operated to press the pair of centering blocks 72 against the wall surfaces. At this time, by adjusting the position of each centering block 72 in the third direction D3, the position of the contact portion 52 in the third direction D3 can be adjusted so that the positions of the sensor portion 54 and the contact portion 52 in the third direction D3 coincide with each other.
[0102] (5) The inspection device 50 of a fifth aspect is any one of the inspection devices 50 of (1) to (4), and further includes a brake mechanism 80 that is arranged at a fixed position in the first direction D1 and the third direction D3 with respect to the contact portion 52 and prevents the contact portion 52 from shifting in the second direction D2, and the brake mechanism 80 may have a brake block 82 that is movable in a direction intersecting the second direction D2.
[0103] For example, when there are wall surfaces on both sides of the inspection device 50 in a direction intersecting with the second direction D2, the brake mechanism 80 can be operated to press the brake block 82 against the wall surfaces. This makes it possible to prevent the inspection device 50 from shifting in position in the second direction D2 against the reaction force that the contact portion 52 receives from the seal portion 8.
[0104] (6) The inspection system 1 of the sixth aspect includes an inspection device 50 selected from any one of (1) to (5), a pipe 6 connected to the inspection device 50 from the second direction D2, and a moving mechanism 15 that grasps the end of the pipe 6 opposite the inspection device 50 in the second direction D2 and moves the pipe 6 in the second direction D2.
[0105] This makes it possible to automatically position the inspection device 50 relative to the surface 5 to be inspected in the second direction D2.
[0106] (7) The inspection system 1 of a seventh aspect is the inspection system 1 of (6), wherein the inspection device 50 further includes a connecting pipe 91 extending in the second direction D2 and a connecting member 20 connecting the pipe 6 and the connecting pipe 91, and the connecting member 20 may have a central axis portion 21 extending in the second direction D2 and having one end in the second direction D2 inserted into either the pipe 6 or the connecting pipe 91 and the other end in the second direction D2 inserted into the other of the pipe 6 or the connecting pipe 91, male thread portions 22 provided at both ends of the central axis portion 21 in the second direction D2 and capable of screwing into inner surfaces of the pipe 6 and the connecting pipe 91, and a flange portion 23 extending radially outward from the outer circumferential surface of the central axis portion 21 at the center in the second direction D2 more than the pipe 6 and the connecting pipe 91.
[0107] The connecting member 20 is firmly fixed to both the pipe 6 and the connecting pipe 91 of the inspection device 50 by the male thread portion 22. In addition, the flange portion 23 protrudes radially outward beyond the pipe 6 and the connecting pipe 91. This makes it possible to prevent the pipe 6 and the connecting pipe 91 from colliding with the surrounding inspected surface 5, etc. [Explanation of symbols]
