[0016] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. Dimensions, materials, and other specific numerical values shown in the embodiments are merely examples for ease of understanding and, unless otherwise specified, do not limit the present disclosure. In this specification and drawings, elements having substantially the same functions and configurations are designated by the same reference numerals to avoid redundant explanation, and elements not directly related to the present disclosure are not shown.
[0017] FIG. 1 is a schematic perspective view illustrating the configuration of the repair device 100 according to the first embodiment. FIG. 2 is a schematic side view illustrating the configuration of the repair device 100 according to the first embodiment. As shown in FIGS. 1 and 2, the repair device 100 includes an attachment device 200, a pressing device 300, a heating device 400, a suction device 500, and a control device 600. The repair device 100 is an apparatus for repairing a composite member 700.
[0018] The composite member 700 is a composite of reinforcing fibers and resin. In the first embodiment, the resin of the composite member 700 is a thermoplastic resin, and the reinforcing fibers of the composite member 700 are carbon fibers. However, the reinforcing fibers of the composite member 700 are not limited to carbon fibers, and may be, for example, glass fibers or aramid fibers. In this way, the composite member 700 of the first embodiment is configured to include a thermoplastic fiber-reinforced resin.
[0019] Composite member 700 has, for example, a flat plate shape. Composite member 700 has a first surface 710, which is the surface, and a second surface 720. Furthermore, damaged portion 730 is formed inside composite member 700. Here, damaged portion 730 is a portion where internal damage such as delamination or cracks has occurred.
[0020] The damaged area 730 formed inside the composite member 700 can be detected by a flaw detection sensor (not shown). The flaw detection sensor (not shown) is, for example, an eddy current flaw detection sensor or an ultrasonic flaw detection sensor. By using the flaw detection sensor, the position of the damaged area 730 formed inside the composite member 700 can be identified non-destructively. Once the position of the damaged area 730 in the composite member 700 has been identified, the repair device 100 is placed at the damaged area 730 using a robot device (not shown). Then, the repair device 100 is attached to the damaged area 730 in the composite member 700 using the attachment device 200.
[0021] Mounting device 200 includes a frame 210, an electromagnet 220, and a metal plate 230. Frame 210 is disposed opposite first surface 710 of composite member 700. Frame 210 has a main body 212 and a plurality of supports 214. Main body 212 is, for example, disk-shaped, and is disposed spaced apart from first surface 710 of composite member 700.
[0022] The support 214 has, for example, a cylindrical shape. One end of the support 214 is connected to the main body 212, and the other end of the support 214 is connected to the electromagnet 220. The support 214 is provided so as to extend from the main body 212 toward the electromagnet 220. The multiple supports 214 are provided on the outer periphery of the main body 212 and are arranged at equal intervals from one another in the circumferential direction of the main body 212. However, this is not limited thereto, and the multiple supports 214 may also be arranged at unequal intervals from one another in the circumferential direction of the main body 212.
[0023] In the first embodiment, the number of the plurality of supports 214 is six. However, the number of the plurality of supports 214 is not limited to six, and may be two, three, four, five, or seven or more. Furthermore, the number of supports 214 is not limited to two, and may be one.
[0024] The electromagnet 220 includes a core of magnetic material and an electric wire. The electric wire is wound around the core of magnetic material. The electromagnet 220 can generate a magnetic force by passing a current through the electric wire. The electromagnet 220 has, for example, a cylindrical shape. The electromagnet 220 is connected to the other end of the support 214, thereby being supported by the support 214. One electromagnet 220 is connected to one support 214. Here, the number of electromagnets 220 is the same as the number of supports 214. In the first embodiment, since there are six supports 214, the number of electromagnets 220 is six. Furthermore, since the multiple supports 214 are arranged at equal intervals from one another in the circumferential direction of the main body 212, the multiple electromagnets 220 are also arranged at equal intervals from one another in the circumferential direction of the main body 212. When the repair device 100 is attached to the composite member 700, the multiple electromagnets 220 are arranged between the multiple supports 214 and the composite member 700.
[0025] The metal plate 230 has, for example, a disk shape, which is the same shape as the main body 212. However, without being limited to this, the shape of the metal plate 230 may be different from the shape of the main body 212, and may be, for example, a triangular, rectangular, polygonal, or elliptical shape.
[0026] When the repair device 100 is attached to the composite member 700, the metal plate 230 is disposed opposite the second surface 720, which is the inner surface of the composite member 700. The size of the metal plate 230 is determined according to the position where the electromagnet 220 is disposed. Specifically, the size of the metal plate 230 is such that it can face all of the electromagnets 220 across the composite member 700.
[0027] Metal plate 230 is a metal member and is made of a ferromagnetic metal such as iron, cobalt, or nickel. Therefore, when electromagnet 220 generates a magnetic force, metal plate 230 is attracted to and attached to electromagnet 220. As a result, composite member 700 is sandwiched between electromagnet 220 and metal plate 230, and is held by electromagnet 220 and metal plate 230 while electromagnet 220 is generating a magnetic force. In this way, mounting device 200 is attached to composite member 700.
[0028] The pressing device 300 includes an actuator 310 and a driving member 320. The actuator 310 is connected to the frame 210 by a connecting member (not shown). The actuator 310 is composed of, for example, an electric motor, an electromagnetic solenoid, a servo cylinder, a hydraulic cylinder, or a pneumatic cylinder. The actuator 310 drives the driving member 320 in the axial direction. When the repair device 100 is attached to the composite member 700, the actuator 310 drives the driving member 320 in the axial direction, thereby generating a pressing force that presses the driving member 320 toward the composite member 700.
[0029] The driving member 320 has, for example, a cylindrical shape. One end of the driving member 320 is connected to the actuator 310, and the other end of the driving member 320 is connected to the heating device 400. A through-hole is formed in the center of the main body 212, and the driving member 320 is configured to be insertable into the through-hole of the main body 212. The driving member 320 is inserted into the through-hole of the main body 212, and when the repair device 100 is attached to the composite member 700, the driving member 320 is positioned facing the damaged portion 730 of the composite member 700 via the heating device 400. The driving member 320 presses the heating device 400 against the composite member 700 due to the pressing force generated when the actuator 310 is driven. When the repair device 100 is attached to the composite member 700 and the actuator 310 is driven, the heating device 400 is pressed against the first surface 710 of the composite member 700. That is, in the first embodiment, the heating device 400 is a pressing member that is pressed against the first surface 710 of the composite member 700. Note that the heating device 400 and the driving member 320 may be pressing members that are pressed against the first surface 710 of the composite member 700.
[0030] The heating device 400 has, for example, a cylindrical shape. The heating device 400 is configured, for example, by a heater and generates heat for heating the composite member 700. When the repair device 100 is attached to the composite member 700, the heating device 400 is positioned opposite the damaged portion 730 of the composite member 700. The heating device 400 generates heat to heat the damaged portion 730 of the composite member 700. In other words, the damaged portion 730 of the composite member 700 is the heated portion that is heated by the heating device 400. Note that in the first embodiment, the heating device 400 is integrally connected to the pressing device 300 and is included as part of the pressing device 300. However, this is not limited thereto, and the heating device 400 may be configured separately from the pressing device 300 without being integrally connected thereto, and may not be included as part of the pressing device 300.
[0031] The heating device 400 is configured to be detachable from the driving member 320. One heating device 400 is selected from a preset number of different sizes of heating devices and attached to the driving member 320. A heating device 400 of a size that matches the size of the damaged area 730 is selected from the multiple types of heating devices.
[0032] The suction device 500 includes a sheet member 510, a seal member 520, and a pump 530. The sheet member 510 is formed of a thin film and is arranged on the first surface 710 so as to cover the damaged area 730 of the composite member 700. When the repair device 100 is attached to the composite member 700, the sheet member 510 is arranged between the heating device 400 and the damaged area 730 of the composite member 700. The sheet member 510 also has a suction port 512 formed therein for connection to the pump 530. When the sheet member 510 is arranged on the first surface 710, the suction port 512 is positioned so as to face the damaged area 730, which is the heated portion of the composite member 700.
[0033] The sealing member 520 is disposed between the sheet member 510 and the composite member 700, and seals the gap between the sheet member 510 and the composite member 700. The sealing member 520 seals the gap between the sheet member 510 and the composite member 700, thereby forming an airtight space between the sheet member 510 and the composite member 700.
[0034] The pump 530 is connected to the suction port 512 of the sheet member 510. The pump 530 exhausts gas from the sealed space between the sheet member 510 and the composite member 700 via the suction port 512, creating a vacuum.
[0035] The control device 600 is electrically connected to the electromagnet 220 , the actuator 310 , the heating device 400 , and the pump 530 , and controls the driving of the electromagnet 220 , the actuator 310 , the heating device 400 , and the pump 530 .
[0036] 3 is a schematic block diagram of a control device 600 according to the first embodiment. As shown in Fig. 3, the control device 600 includes an I / F 610, a storage device 620, a system bus 630, one or more processors 640, and one or more memories 650. The I / F 610 is an interface for transmitting signals to and from the electromagnet 220, the actuator 310, the heating device 400, and the pump 530.
[0037] The storage device 620 is composed of RAM, flash memory, HDD, etc., and holds various information necessary for processing by the processor 640. The system bus 630 electrically connects the I / F 610, storage device 620, processor 640, and memory 650, and is a transmission path for transmitting data among them.
[0038] The processor 640 includes, for example, a CPU (Central Processing Unit). The memory 650 includes, for example, a ROM (Read Only Memory) and a RAM (Random Access Memory). The ROM is a storage element that stores programs and calculation parameters used by the CPU. The RAM is a storage element that temporarily stores data such as variables and parameters used in processing executed by the CPU.
[0039] Fig. 4 is a block diagram showing an example of the functional configuration of the control device 600 according to the first embodiment. For example, as shown in Fig. 4, the control device 600 includes a drive control unit 600a.
[0040] The various processes performed by the drive control unit 600a can be executed by the processor 640 in cooperation with programs stored in the memory 650. In particular, the various processes are performed by the processor 640 executing the programs stored in the memory 650.
[0041] The drive control unit 600a controls the current flowing through the electromagnet 220. By controlling the current flowing through the electromagnet 220, the attraction force between the electromagnet 220 and the metal plate 230 can be controlled, and the attachment and detachment of the mounting device 200 to the composite member 700 can be controlled.
[0042] Drive control unit 600a controls the driving of actuator 310, and controls the pressing force that drive member 320 applies to composite material 700 via heating device 400. Drive control unit 600a also controls the driving of heating device 400, and controls the amount of heat that heating device 400 applies to composite material 700. This allows damaged area 730 of composite material 700 to be heated by heating device 400 while being pressurized.
[0043] Drive control unit 600a controls the drive of pump 530, and controls the suction force that draws gas from the sealed space between sheet member 510 and composite member 700. When composite member 700 containing thermoplastic resin is heated, gas is generated, and air bubbles may form inside composite member 700. By having pump 530 draw gas from the sealed space between sheet member 510 and composite member 700 through suction port 512, it is possible to prevent air bubbles from forming inside composite member 700, and as a result, it is possible to prevent a decrease in the strength of composite member 700.
[0044] When damage occurs to a composite material, a common method for repairing the damaged composite material is to scrape off the damaged area and then glue a repair material to the scraped-off area.
[0045] However, the repair time for the composite material to be repaired was lengthened due to the need for drying time before the repair material was bonded and the need for curing time for the adhesive after the repair material was bonded.
[0046] Therefore, the repair device 100 according to the first embodiment applies heat and pressure to the damaged area 730 of a composite member 700 containing a thermoplastic fiber-reinforced resin, thereby repairing the damaged area 730 by thermal fusion. This eliminates the need for drying time before bonding the repair material and the hardening time after bonding when repairing the composite member 700, thereby shortening the time required to repair the composite member 700. While repair of composite members is sometimes performed manually by craftsmen, the present disclosure allows the repair of the composite member 700 to be performed automatically without relying on skilled craftsmen. As a result, the composite member 700 can be easily repaired. Below, details of the repair process in the method for repairing the damaged area 730 of a composite member 700 using the repair device 100 according to the first embodiment will be described.
[0047] 5 is a flowchart of the repair process for the damaged portion 730 of the composite member 700 according to the first embodiment. As shown in FIG. 5, first, a damage detection process is executed (S100) in which a flaw detection sensor (not shown) detects damage to the composite member 700. The drive control unit 600a determines whether or not the composite member 700 is damaged based on the results of the damage detection process (S102). If the composite member 700 is not damaged (NO in S102), the drive control unit 600a ends the repair process.
[0048] If the composite member 700 is damaged (YES in S102), the drive control unit 600a identifies the position of the damaged portion 730 of the composite member 700 based on the results of the damage detection process, and uses a robot device (not shown) to place the repair device 100 at the damaged portion 730. Then, the drive control unit 600a applies a current to the electromagnet 220 to generate a magnetic force, thereby sandwiching the composite member 700 between the electromagnet 220 and the metal plate 230. This causes the mounting device 200 to be mounted on the composite member 700 (S104).
[0049] The drive control unit 600a drives the heating device 400 to heat the damaged area 730 of the composite material 700 (S106). The drive control unit 600a also drives the actuator 310 to drive the driving member 320 in the axial direction, causing the heating device 400 to press against the damaged area 730 of the composite material 700 (S108). The drive control unit 600a also drives the pump 530 to suck gas from the sealed space between the sheet member 510 and the composite material 700 (S110).
[0050] Thereafter, the drive control unit 600a determines whether a predetermined time has elapsed using a timer (not shown) (S112). If the predetermined time has not elapsed (NO in S112), the drive control unit 600a continues the processes of S106 to S110. On the other hand, if the predetermined time has elapsed (YES in S112), the drive control unit 600a stops the driving of the heating device 400, the actuator 310, and the pump 530 (S114) and ends the repair process. Note that here, an example has been described in which the drive control unit 600a controls the driving of the heating device 400, the actuator 310, and the pump 530 based on time. However, this is not limiting, and the drive control unit 600a may also control the driving of the heating device 400, the actuator 310, and the pump 530 based on, for example, the pressure (vacuum level) in the sealed space between the sheet member 510 and the composite member 700. Specifically, the drive control unit 600a may stop driving the heating device 400, the actuator 310, and the pump 530 when the pressure in the sealed space between the sheet member 510 and the composite member 700 falls below a predetermined value based on the pressure of a pressure gauge not shown.
[0051] As described above, the repair device 100 of the first embodiment includes the mounting device 200, the pressing device 300, and the heating device 400, each connected to the mounting device 200. The mounting device 200 is attached to a composite member 700 containing a thermoplastic fiber-reinforced resin, and the heating device 400 heats the composite member 700. The pressing device 300 presses the damaged area 730, which is the portion of the composite member 700 that is heated by the heating device 400. This eliminates the need for adhesive when repairing the composite member 700, eliminating the drying time before and the hardening time after bonding of the repair material, thereby shortening the time required to repair the composite member 700. Furthermore, the repair of the composite member 700 can be performed automatically without relying on a skilled craftsman. As a result, the composite member 700 can be easily repaired.
[0052] Furthermore, the repair device 100 of the first embodiment repairs the damaged area 730 of the composite member 700 by thermal fusion, without scraping off the damaged area 730. This prevents the fibers contained in the composite member 700 from being cut, thereby preventing a decrease in the strength of the composite member 700. Furthermore, the repair device 100 makes it possible to automate the repair of the damaged area 730, eliminating the need for manual work by a skilled craftsman and reducing the cost of repair.
[0053] The mounting device 200 also includes an electromagnet 220 and a metal plate 230 that is attracted by the electromagnet 220, and is attached to the composite member 700 by sandwiching the composite member 700 between the electromagnet 220 and the metal plate 230. Here, a pressing force of at least a certain level is required for repair by thermal fusion. The magnitude of the force that attracts the metal plate 230 by the magnetic force of the electromagnet 220 can be made greater than the pressing force required for repair by thermal fusion. Therefore, when repairing the composite member 700, if the actuator 310 generates a pressing force, it is possible to prevent the mounting device 200 from falling off the composite member 700.
[0054] The repair device 100 also includes a suction device 500. The suction device 500 includes a sheet member 510, a sealing member 520, and a pump 530. The sheet member 510 has a suction port 512 facing a damaged area 730, which is a heated portion of the composite member 700. When a composite member 700 containing a thermoplastic resin is heated, gas is generated, and air bubbles may be generated inside the composite member 700. The pump 530 sucks gas from the sealed space between the sheet member 510 and the composite member 700 through the suction port 512, thereby preventing air bubbles from being generated inside the composite member 700. As a result, air bubbles can be prevented from being generated inside the composite member 700, and a decrease in the strength of the composite member 700 can be prevented.
[0055] 6 is a schematic side view for explaining the configuration of a repair device 1100 according to the second embodiment. Components that are substantially the same as those in the repair device 100 according to the first embodiment are given the same reference numerals and will not be described.
[0056] 6, the mounting device 1200 of the second embodiment includes an adsorption device 1220 instead of the electromagnet 220 and the metal plate 230. When the repair device 1100 is attached to the composite member 700, the adsorption device 1220 is disposed between the support 214 and the composite member 700. The adsorption device 1220 is connected to and supported by the support 214.
[0057] The suction device 1220 is connected to the pump 530, and is attached to the composite member 700 by the suction force of the pump 530. In this way, the attachment device 1200 is attached to the composite member 700.
[0058] According to the second embodiment, the metal plate 230 of the mounting device 200 of the first embodiment can be eliminated, and the device configuration can be made smaller and simpler than when the electromagnet 220 and the metal plate 230 are provided.
[0059] 7 is a schematic side view for explaining the configuration of a repair device 2100 according to the third embodiment. Components that are substantially the same as those in the repair device 100 according to the first embodiment are given the same reference numerals and will not be described.
[0060] 7, an inclined portion 710a is formed on a first surface 710 of a composite member 700 of the third embodiment. In the third embodiment, the portion of the first surface 710 other than the inclined portion 710a is a flat surface, but the inclined portion 710a is inclined from the flat surface.
[0061] The pressing device 2300 of the third embodiment also includes a driving member 320. The driving member 320 has a contact surface 320a that comes into contact with the heating device 2400. The contact surface 320a of the driving member 2320 is a flat surface and has a different shape from the first surface 710 that has the inclined portion 710a.
[0062] On the other hand, the heating device 2400 of the third embodiment is pressed against a first surface 710, which is the surface of the composite member 700, and has an opposing surface 2400a facing the first surface 710. The shape of the opposing surface 2400a of the heating device 2400 corresponds to the shape of the first surface 710, which has the inclined portion 710a. Specifically, the opposing surface 2400a of the heating device 2400 faces the inclined portion 710a of the first surface 710, and has a shape corresponding to the outer shape of the first surface 710, including the inclined portion 710a. For example, the inclination angle of the opposing surface 2400a of the heating device 2400 may be the same as the inclination angle of the inclined portion 710a. Here, "same" means both completely the same and deviating from the completely same case within the range of tolerance (such as processing accuracy or assembly error).
[0063] According to the third embodiment, the shape of the opposing surface 2400a of the heating device 2400 corresponds to the shape of the first surface 710 of the composite material 700. Here, for example, if the shape of the opposing surface 2400a is different from the shape of the first surface 710 of the composite material 700, the surface shape of the composite material 700 will deform to match the shape of the opposing surface 2400a during repair by thermal fusion. Since the shape of the opposing surface 2400a of the heating device 2400, which is a pressing member, corresponds to the shape of the first surface 710, the first surface 710 of the composite material 700 can be pressed uniformly. In the third embodiment, the heating device 2400, which is a pressing member, is a heater, and since the shape of the opposing surface 2400a corresponds to the shape of the first surface 710, the first surface 710 of the composite material 700 can be heated uniformly. As a result, the damaged portion 730 can be repaired while maintaining the surface shape of the composite material 700 during thermal fusion.
[0064] 8 is a schematic side view for explaining the configuration of a repair device 3100 according to the fourth embodiment. Components that are substantially the same as those in the repair device 2100 according to the third embodiment are given the same reference numerals and will not be described.
[0065] 8, a first surface 710 of a composite member 700 of the fourth embodiment has an inclined portion 710a formed thereon, similar to the third embodiment. In the fourth embodiment, the portion of the first surface 710 other than the inclined portion 710a is a flat surface, but the inclined portion 710a is inclined from the flat surface.
[0066] Furthermore, the pressing device 3300 of the fourth embodiment includes an elastic member 3410 in addition to the heating device 400 which is the pressing member of the first embodiment. The driving member 320 has a contact surface 320a which comes into contact with the heating device 400. The contact surface 320a of the driving member 320 is a flat surface and has a shape different from that of the first surface 710 which has the inclined portion 710a.
[0067] Furthermore, the heating device 400 of the fourth embodiment has a contact surface 400a that comes into contact with the elastic member 3410. The contact surface 400a of the heating device 400 is a flat surface, and has a different shape from the first surface 710 that has the inclined portion 710a.
[0068] In the fourth embodiment, an elastic member 3410 is interposed between the heating device 400 and the composite member 700. The elastic member 3410 is made of, for example, rubber. The elastic member 3410 is configured to be able to transmit a pressing force from the driving member 320 to the composite member 700 by being interposed between the driving member 320 and the composite member 700. The elastic member 3410 is also configured to be able to transmit heat from the heating device 400 to the composite member 700 by being interposed between the heating device 400 and the composite member 700. The elastic member 3410 is configured to be able to deform according to the surface shape of the first surface 710 of the composite member 700 when it receives a pressing force from the driving member 320.
[0069] According to the fourth embodiment, the contact surface 320a of the driving member 320 and the contact surface 400a of the heating device 400 have different shapes from the first surface 710 of the composite member 700. However, an elastic member 3410 is interposed between the heating device 400 and the composite member 700. The elastic member 3410 deforms to a shape corresponding to the first surface 710, thereby uniformly pressing the first surface 710 of the composite member 700. Furthermore, the elastic member 3410 can transfer heat from the heating device 400 to the composite member 700 while deformed to a shape corresponding to the first surface 710 of the composite member 700. As a result, even if the shapes of the contact surface 320a and the contact surface 400a are different from the first surface 710 of the composite member 700, the damaged portion 730 can be repaired while maintaining the surface shape of the composite member 700 during thermal fusion.
[0070] Although the embodiments of the present disclosure have been described above with reference to the accompanying drawings, it goes without saying that the present disclosure is not limited to such embodiments. It is clear that a person skilled in the art can conceive of various modifications and alterations within the scope of the claims, and it is understood that such modifications and alterations also fall within the technical scope of the present disclosure.
[0071] In the first embodiment described above, an example has been described in which the repair device 100 includes the suction device 500. However, the suction device 500 is not an essential component, and the repair device 100 does not necessarily need to be provided with the suction device 500. Furthermore, in the first embodiment described above, an example has been described in which the repair device 100 is placed at the damaged area 730 using a robot device. However, this is not limiting, and for example, the repair device 100 may be placed at the damaged area 730 by hand of an operator.
[0072] In the first embodiment, an example in which the heating device 400 is a heater has been described. However, this is not limiting, and the heating method of the heating device 400 can be changed to a method such as induction heating or dielectric heating. The heating device 400 may also be, for example, a heat gun. The heat gun may be connected to and supported by the mounting device 200. When the heating device 400 is configured as a heat gun, the composite member 700 can be heated in a non-contact manner by blowing high-temperature hot air from the heat gun. In this case, the heat gun does not need to be located between the driving member 320 and the composite member 700. The driving member 320 may be a pressing member that directly contacts the composite member 700 and presses it against the composite member 700. In the first embodiment, the surface of the heating device 400, which is a pressing member, facing the first surface 710 and the surface of the heating device 400, which is a heater, facing the first surface 710 are surfaces of the same member, but they may be surfaces of different members. That is, when the driving member 320 is a pressing member, the surface of the driving member 320 that is a pressing member and the surface of the heating device 400 that is a heater and the surface of the heating device 400 that is a heater and the surface of the heating device 400 that is a heater and the surface of the heating device 400 that is a heater are surfaces of different members.
