Abstract
Description
Technical Field
[0001] This disclosure relates to the field of aircraft, and more specifically, to the manufacture of aircraft. Background Technology
[0002] To trim the edges of composite parts forming aircraft components, the composite part is moved into a cell and scanned for detail. In this way, the composite part is indexed and characterized relative to a mold within the cell. Next, a single trimming device trims the periphery to the final part size by removing manufacturing excess. Therefore, trimming is performed by carefully advancing a trimmer around the entire periphery of the composite part within a cell specifically built for trimming purposes. This single trimmer operates on the entire composite part simultaneously. At this point, no further operations can be performed within the cell. The composite part is moved to another cell before further operations can be performed; thus, upon moving to each new cell, the composite part must be scanned for indexing / performing a three-dimensional (3D) characterization of the composite part.

[0014] Therefore, it is desirable to have methods and equipment that take into account at least some of the problems discussed above, as well as other possible problems. In other words, the manufacturing operation density per unit area of the current manufacturing system used for assembling aircraft is lower than the desired manufacturing operation density. Summary of the Invention
[0015] The embodiments described herein provide stations supporting edge trimming, which remove manufacturing excess from multiple aircraft fuselage sections advancing in a processing direction during assembly. During these processes, multiple fuselage sections can advance in series to receive work from the edge trimming station. Furthermore, multiple edge trimming stations can be arranged in series to provide roughing and fine trimming operations as desired (e.g., within the same time period at the same fuselage section). One embodiment is a method for inspecting a structure. The method includes: advancing the structure along a track in a processing direction; aligning a non-destructive testing (NDI) station at the track with an edge of the structure trimmed upstream of the NDI station; imaging the edge via the NDI station; characterizing the edge based on the imaging step; and further advancing the structure in the processing direction via the track.
[0016] Another embodiment is a non-transitory computer-readable medium containing program instructions that, when executed by a processor, operate to perform a method for inspecting a structure. The method includes: advancing the structure along a track in a processing direction; aligning a non-destructive testing (NDI) station at the track with an edge of the structure trimmed upstream of the NDI station; imaging the edge via the NDI station; characterizing the edge based on the imaging step; and further advancing the structure in the processing direction via the track.
[0017] Another embodiment is a system for inspecting a structure. The system includes: a track that supports the structure from its edge while contacting the edge, allowing the structure to move in a processing direction; and a non-destructive testing (NDI) station that characterizes the edge of the structure as it is advanced in the processing direction via the track.
[0018] Another embodiment is a system for inspecting a structure. The system includes: a structure conveyor that supports the structure at its final cut edge while contacting any excess material in the structure, allowing the structure to move in a processing direction; and a non-destructive testing (NDI) station located at the structure conveyor for inspecting the final cut edge of the structure.

[0039] The accompanying drawings and the following description provide specific exemplary embodiments of this disclosure. Therefore, it will be understood that those skilled in the art will be able to devise various arrangements that, while not expressly described or shown herein, implement the principles of this disclosure and are included within its scope. Furthermore, any examples described herein are intended to aid in understanding the principles of this disclosure and are to be construed as not being limited to such specific examples and conditions. Consequently, this disclosure is not limited to the specific embodiments or examples described below, but is defined by the claims and their equivalents.
[0040] The structures described herein can include composite or metallic parts. Composite parts, such as carbon fiber reinforced polymer (CFRP) parts, are initially laid out in multiple layers, which together are referred to as a preform. Individual fibers within each layer of the preform are aligned parallel to each other, but different layers exhibit different fiber orientations to increase the strength of the final composite part along different dimensions. The preform includes a viscous resin that cures to harden the preform into a composite part (e.g., for use in aircraft). Carbon fibers impregnated with uncured thermosetting or thermoplastic resins are referred to as “prepregs.” Other types of carbon fibers include “dry fibers,” which are not impregnated with thermosetting resins but may include tackifiers or binders. Dry fibers are injected with resin and then cured. For thermosetting resins, curing is a unidirectional process called curing, while for thermoplastic resins, if the resin is reheated, it reaches a viscous form.
[0041] Figure 1 This is a block diagram of a pipeline assembly system 100 in an exemplary embodiment, which significantly increases the manufacturing operation density per unit area for assembling aircraft. Specifically, in addition to performing peripheral trimming during and / or between pulses, the pipeline assembly system 100 increases the number of manufacturing operations per square foot by performing multiple operations on the same segment of a composite part.
[0042] The assembly line system 100 includes any system, apparatus, or component operable to iteratively pulse a structure 120 (e.g., less than the full length of the structure) along a structure conveyor 102 (e.g., track 110) and perform work on the structure 120 while pausing between pulses. In other embodiments, the assembly line system 100 continuously moves the structure 120 at a desired rate in a processing direction 199 while performing work.
[0043] Structure 120 includes a part of the body, such as a fuselage segment. Figure 1In the embodiment depicted, structure 120 includes a semi-cylindrical section of fuselage approximately 7.6m to 12.2m long (25 to 40 feet), the semi-cylindrical section including a window cutout 128 and a manufacturing excess 124 disposed at the lower edge of structure 120. Additional manufacturing excesses 121 are found at the leading and trailing edges of structure 120. The manufacturing excess 124 includes a bearing edge 125 and an indexing feature 126, which upstream stations can utilize to perform work on structure 120. In one embodiment, the bearing edge 125 and the indexing feature 126 are provided for multiple stations to perform work on multiple (e.g., different) sections 127 of structure 120 within the range of multiple stations. In other embodiments, structure 120 may, as desired, include any suitable arcuate section of fuselage, such as one-third, one-quarter, or one-sixth of a fuselage cylindrical section. In the following text, any bow-shaped fuselage section is referred to as a "tube" section, while a "full tube" section refers to a fuselage section comprising an arc forming a complete circle (i.e., a joined upper and lower tube section). In other embodiments, structure 120 includes hardened composite material or metal parts, such as skinned sections of aircraft, in which stringers and / or frames have been installed to enhance rigidity.
[0044] The assembly line system 100 includes a track 110 that contacts and supports the manufacturing excess portion 124 of the structure 120 as it advances in the processing direction 199. The track 110 includes one or more guide rails, supports with rollers or grooves, and other elements that facilitate movement (e.g., rolling or sliding) of the structure 120 along the track 110 while also forcing a desired position and / or orientation on the structure 120. In other embodiments, the track 110 includes a chain drive, a motorized trolley, powered rollers, or other power system capable of moving the structure 120 in the processing direction 199. As the structure 120 advances in the processing direction 199, the manufacturing excess portion 124 reaches a trimming station 140. In one embodiment, multiple trimming stations 140 operate on the structure 120 during its passage through the trimming stations 140.
[0045] The trimming station 140 includes a cutter head 142, such as an actuated cutting tool capable of reciprocating along the processing direction 199. In some exemplary examples, movement in or parallel to the processing direction 199 is referred to as horizontal movement. In some exemplary examples, the cutter head 142 operates horizontally to remove manufacturing excess 124 from the structure 120. The controller 144 controls the operation of the trimming station 140, for example, by: activating a tool (e.g., a reciprocating insert, a circular insert, a punch, etc.) at the cutter head 142; moving the cutter head 142; receiving input from a sensor 146 (e.g., a motion sensor, a laser, an ultrasonic sensor, or a visual positioning sensor, etc.) indicating pauses between pulses in the structure 120, etc. The indexing / characterization discussed herein ensures that trimming is performed in the desired position. In one embodiment, trimming includes engagement during indexing to determine the position. The indexing method for each downstream assembly station will depend on the positional accuracy requirements necessary for the type of job being performed. As an example, the window frame installation position can have more permissible tolerances because no further structural integration occurs after the window frame is installed. In contrast, the frame is integrated with other frames and the floor, so their positional requirements are more tightly controlled. The inversion feature 126 can convey specific instructions for a particular operation. For example, position, configuration, and type can convey specific instructions. In this case, just before the inversion feature is cut off as part of the pulsation process, the inversion feature helps to position the half-body relative to the trim line with each pulsation.
[0046] In this implementation, the trimming station 140 is configured to facilitate insertion to grip or otherwise engage with the indexing feature 126. During assembly, the structure 120 is pulsated a distance (e.g., at least equal to the shortest distance between the indexing features 126, the frame pitch, the distance equal to the length of each section 127, etc.) and indexed to the trimming station 140 when the cutter head 142 operates on the structure 120. The track 110 enforces the desired position of the structure 120 in / out of the page. Furthermore, whenever the indexing feature 126 in the structure 120 matches the trimming station 140, the position of the structure 120 is indexed to a known position in the coordinate space shared by the track 110 and the cutter head 142. In addition, the indexing also applies forces transmitted from one side to the other through the structure 120, thereby forcing the loft in the structure 120 and causing the structure 120 to maintain the desired loft. In other words, any outward bending force applied to the sides of structure 120 is resisted by track 110, resulting in maintaining the arc shape, allowing track 110 to force conformation to the desired mold line, inner mold line (IML), and / or outer mold line (OML). This also prevents the introduction of distortion into structure 120 during pulsation. In other embodiments, structure 120 maintains the desired IML and / or OML shape without externally applied forces (i.e., forces beyond those applied by the rollers that propel structure 120 along track 110). In any case, structure 120 conforms to the desired IML and / or OML when it receives work from trimming station 140. Specifically, the action of transposing structure 120 to trimming station 140 results in the position of structure 120 relative to trimming station 140 being known. In this way, a 3D representation of structure 120 within the range of the station is conveyed to the station without needing to scan structure 120 at each station stop. The width of track 110, along with the shape of the cylindrical section and the delay in cutting until after the installation of the frame, window and door surrounds, as well as other possible means of maintaining the desired curvature, help ensure that the configuration is as desired when the section is rotated at a particular workstation, and also help maintain the desired stiffness / rigidity.
[0047] In one embodiment, the indexing is performed at least according to the following description. A cylindrical segment-shaped structure 120 is supported on a track 110. The track 110 may include elements such as powered rollers mounted on a discrete series of supports arranged in the processing direction 199, or tracks (e.g., mounted to or raised above a floor). The elements of the track 110 are positioned in known locations. The cylindrical segment is manufactured on a laying mandrel according to precise dimensions. Furthermore, the mandrel has precise features that facilitate the positioning of features within the manufacturing excess 124 of the cylindrical segment, and this precise laying allows the indexing feature 126 to be precisely positioned within the manufacturing excess 124 of the cylindrical segment. At this stage, in one embodiment, a radio frequency identifier (RFID) chip is placed within the manufacturing excess 124. Once the cylinder segment is positioned on a precisely positioned track element (and possibly an additional inner mold line (IML) or outer mold line (OML) forced realization tool located upstream or downstream of the station), the 3D position of the cylinder segment and the IML or OML mold line are accurately known when the indexing feature is engaged, without the need for a complete scan at each station via probes or optical technology.
[0048] The relative stiffness of the demolded or otherwise formed cylinder segments can be relied upon to help maintain the desired mold lines / IML / OML along with precisely positioned track elements that facilitate the transport of the cylinder segments without requiring any substantial shape-defining tools during pulse assembly. In this arrangement, features are precisely positioned within the cylinder segments relative to the mold lines / IML / OML of structure 120, and the precisely positioned track elements help transport the cylinder segments from one station to another without distortion. Therefore, the 3D position and orientation (e.g., including the mold lines / IML / OML) of the cylinder segments can be known quickly and accurately (i.e., indexed) after each pulse without requiring rescanning of the cylinder segments each time.
[0049] Because precise indexing is performed, the cutter heads 142 at the trimming station 140 can know precisely their positions relative to the cylinder segment when it is locked in place. The 3D position and orientation of the cylinder segment and / or mold lines / IML / OML are then established or indexed into any CNC programming or automation system used at the station. Therefore, no time setting or scanning is required after each pulse of the cylinder segment. Furthermore, structures added to or removed from the cylinder segment in previous stations can be added to any cylinder segment model or representation within the system without needing to scan changes in the cylinder segment. Manufacturing excess 124 is cut from structure 120 to obtain chips 150 of any suitable length or size (e.g., a length equal to or a portion of the pulse length), which are removed from structure 120 and fall into a chute 160 (e.g., a gravity chute). Chips 150 include the removed manufacturing excess 124.
[0050] This removes the indexing feature 126 utilized by the upstream station performing the work on structure 120 and / or by the trimming station 140. The indexing feature 126 is separated as the excess manufacturing portion 124 is trimmed into a trimmed edge (e.g., an intermediate trimmed edge or a final trimmed edge 129). Removing the excess manufacturing portion 124 separates the indexing feature 126 utilized by the upstream station performing the work on structure 120 from structure 120. Structure 120 advances in the processing direction 199 after trimming to obtain the final trimmed edge 129. The portion 127 of structure 120 downstream of the trimming station 140 is carried along a second structural conveyor 104 including an additional second track 112 having a different height than track 110. That is, the second structural conveyor 104 has a second height that allows structure 120 to move in the processing direction 199 and is greater than a first height, and the second structural conveyor 104 is positioned downstream of structural conveyor 102. The height difference corresponds to the height of the excess manufacturing portion 124 after it has been cut off. For example, the second track 112 may include a post sized to support the structure 120 at the trimmed final cut edge 129. Thus, the trimming station 140 leaves the final cut edge 129, which accommodates the splice and contacts the second structure conveyor 104. Therefore, track 110 operates as a first track, supporting the structure 120 while carrying the excess manufacturing portion 124 of the structure 120 (e.g., including the carrying edge 125), and allowing the structure 120 to move in the processing direction 199. The second track 112 operates to support the structure 120 while carrying the cut edge of the structure 120 (e.g., another carrying edge or the final cut edge 129), and allowing the structure 120 to move in the processing direction 199 after the excess manufacturing portion 124 has been removed. In these exemplary examples, the method includes positioning the final cut edge 129 of structure 120 in contact with the track 112 of structure conveyor 104, such that track 112 supports structure 120 from the final cut edge 129. The second track 112 is higher than track 110 by the height of the manufacturing excess 124. Furthermore, when structure 120 includes a half-tube section of the fuselage, the first track 110 supports the manufacturing excess 124 on each side of the half-tube section, and the second track 112 supports the final cut edge 129 on each side of the half-tube section.
[0051] The operation of the trimming station 140 is managed by a controller 144. In one embodiment, the controller 144 determines the advance of the structure 120 along the track 110 (e.g., based on input from a technician or sensor 146) and the position / orientation of the structure 120 relative to the trimming station 140 (e.g., using the same indexing system as an upstream manufacturing station), and uses this input to manage the operation of the trimming station 140 according to instructions stored in a numerical control (NC) program. For example, the controller 144 may modify the instructions in the NC program for the trimming station 140 to accommodate any deviation of the position of the structure 120 from its nominal position and orientation. The controller 144 may be implemented as, for example, custom circuitry, a hardware processor executing program instructions, or some combination thereof.
[0052] exist Figure 1 The diagram also depicts an edge sealing station 170. Edge sealing station 170 applies edge sealant 172 to the newly cut final cut edge 129. Sealant 172 protects the final cut edge 129 from abrasion and prevents the propagation of inconsistencies from the final cut edge 129. Non-destructive testing (NDI) station 180 operates ultrasonic, visual, or laser sensors to scan the final cut edge 129 for out-of-tolerance conditions (e.g., voids, debris, etc.). NDI station 180 is located upstream of edge sealing station 170 to inspect the final cut edge 129 before it is sealed.
[0053] Will target Figure 2 The following are exemplary details of the operation of the assembly line system 100. It is assumed that, for this embodiment, structure 120 has begun to pulsate less than its length in the processing direction 199.
[0054] Figure 2 This is a flowchart illustrating a method 200 for trimming a structure (e.g., structure 120) in an exemplary embodiment. (See reference...) Figure 1 The steps in method 200 are described in the context of a streamlined assembly system 100, but those skilled in the art will understand that method 200 can be performed in other systems. Not all steps in the flowcharts described herein are included, and other steps not shown may be included. The steps described herein may also be performed in an alternative order.
[0055] In step 202, the carrier edge 125 is cut into a manufacturing excess 124 of the structure 120. This may include demolding the structure 120 from a laying mandrel (not shown) after cutting to remove burrs, including resin and / or excess fibers, from the structure 120. As manufacturing continues, the carrier edge 125 is carried by the track 110, and the structure 120 is transported in the processing direction 199. Utilizing the manufacturing excess 124 as the carrier edge 125 (and / or retaining the indexing feature 126 or carrying an RFID chip for instructions to downstream stations) allows the manufacturing excess 124 to provide value during the manufacturing process. That is, unlike existing systems that trim the manufacturing excess 124 into non-value-adding waste, this technology provides a valuable manufacturing excess 124 by facilitating processing and manufacturing in a post-curing environment. This technology provides the additional benefit of protecting the final cut edge 129 of the composite part from damage during transport.
[0056] In step 204, the manufacturing excess portion 124 of structure 120 is positioned to contact structure conveyor 102 (e.g., track 110). Thus, track 110 supports and guides structure 120 by carrying the manufacturing excess portion 124. The manufacturing excess portion 124 may be placed within a notch or groove defined by a support at track 110 and may be positioned on a roller at track 110 that facilitates movement of structure 120 in the processing direction 199.
[0057] In step 206, structure 120 is advanced toward trimming station 140 along structure conveyor 102 (e.g., track 110) in processing direction 199. This may include operating a system that drives track 110 or operating a system that pushes or pulls structure 120 along track 110. In some exemplary examples, advancing structure 120 along track 110 in processing direction 199 includes pulsating structure 120 in processing direction 199. In some exemplary examples, advancing structure 120 along track 110 in processing direction 199 includes moving structure 120 continuously in processing direction 199. Structure 120 may be pulsated (e.g., “micro-pulsations” less than its length) for a predefined distance (e.g., frame pitch indicating the distance between mounted frames) and then paused, or it may be moved continuously along track 110. During the process, the track 110 can hold the structure 120 at a specific height (e.g., within a tolerance such as 25 micrometers (thousandths of an inch), or the trimming station 140 can operate the sensor 146 to detect the height of the structure 120 and then adjust the height of the cutter head 142 to align the cutter to the desired position to form the final trim 129, or even utilize the indexing feature 126.
[0058] In step 208, for each side of structure 120, the trimming station 140 operates to remove manufacturing excess 124 (including the bearing edge 125) from one side of structure 120. Thus, during the same pause or advance of structure 120, the manufacturing excess 124 on both the left and right sides of structure 120 is trimmed. In one embodiment, trimming occurs during the movement of structure 120 over a tool in place, while in another embodiment, trimming is performed by a tool that moves longitudinally relative to structure 120 during a pause. In one embodiment, the sides are trimmed by two different tools (one on each side), which is an improvement over the prior art, which uses a single tool to work the entire edge in a dedicated unit after scanning and transposing structure 120 to the tool.
[0059] Step 208 may include driving the cutter head 142 against the processing direction 199 or driving the cutter head 142 back and forth along the processing direction 199 during cutter movement at the cutter head 142. The trimming operation may be performed during pauses between pulses, during movement of the structure 120 between pauses (e.g., micro-pulsating movement), or during pulsation or during continuous movement of the structure 120. That is, one embodiment utilizes a stationary cutter head 142, wherein the cutting step occurs during pulsating movement in the processing direction 199. When the cutter head 142 is stationary, excess material 124 is removed by a fixed cutter as the structure 120 is pulsated forward. The pulsation may be performed as a “micro-pulsation” at the frame pitch length, so that each cut portion is cut into segments (or cut multiple times to a length less than the micro-pulsation length, or even cut once up to the full pulsation length) at the end of the pulsation and then falls into the chute 160. The trimming station 140 removes manufacturing excess 124 by moving relative to structure 120 in the processing direction 199, moving relative to structure 120 in the opposite direction of processing direction 199, or remaining stationary as structure 120 advances along structure conveyor 102 in the processing direction 199. The segments can be cut using a separate vertical cutter, or the same cutter can be used. Cutting can begin during each pulse, wherein, during the rest period between pulses, the cutter head 142 circulates in the opposite direction to processing direction 199 in a manner similar to a typewriter carriage. In other embodiments, sealing can be performed at the edge sealing station 170 during pauses in the pulses, or via an integrated mechanism located at the trimming station 140.
[0060] In other embodiments, the non-destructive testing (NDI) station 180 and / or the edge sealing station 170 are integrated into the cutter head 142, such that a single scan of the cutter head 142 performs cutting, inspection, and sealing as desired. In other embodiments, the NDI scan and / or sealing are performed when the structure 120 is pulsated (e.g., micro-pulsated), during a pause, or during continuous movement of the structure 120, and the cutter head used to perform the NDI scan and / or sealing is held in place.
[0061] In one embodiment, the cutter head 142 advances vertically after a predefined distance (e.g., after a multiple or a portion of the pulsation length, such as the length corresponding to a micropulsation) to cut the chip 150 into multiple segments of manageable length. In other embodiments, the cutter head 142 vertically cuts the chip 150 from the manufacturing excess portion 124 using a separate cutter, or breaks off fragments of the manufacturing excess portion 124 using a clamping tool (not shown). In other embodiments, the weight of the chip 150 due to gravity causes the chip 150 to separate from the manufacturing excess portion 124. The chip 150 falls into a chute 160 for removal. The chute 160 is located below the trimming station 140.
[0062] In step 210, structure 120 is advanced along structure conveyor 102 in processing direction 199. That is, structure 120 downstream of a cutting station (e.g., trimming station 140) is conveyed at the required height to bear the final trimmed edge 129, while structure upstream of a cutting station (e.g., trimming station 140) is conveyed at the required height to bear the manufacturing excess 124. For example, structure 120 can be pulsed a distance equal to the frame pitch or other distance. Advancing structure 120 in processing direction 199 exposes additional manufacturing excess 124 to trimming station 140, and / or to any NDI station 180 and sealant application station. Steps 206-208 can be performed iteratively until the excess 124 is completely removed, the final trim 129 is fully inspected by non-destructive testing (NDI) and the edge is sealed, and the structure 120 advances its entire length through trimming station 140 and any NDI station 180 and sealant application station (e.g., edge sealing station 170).
[0063] Method 200 offers technological advantages over existing technologies because it makes the transport time of large composite parts a value-added time, where manufacturing and / or assembly continue while the parts are being transported. Therefore, manufacturing and transport actions are integrated, meaning transport time is also operation time. Furthermore, because the operations of the workstations are synchronized according to takt time (i.e., their timing is based on the expected manufacturing rate of the aircraft or a part thereof) in one or more embodiments, the workstations can be chained together to increase work density. This reduces the overall production time of the aircraft, thereby reducing costs. In addition, Method 200 provides a unique technique by which trimming of aircraft components can be performed in a moving assembly line.
[0064] Figures 3 to 4 A trimming station 140 for removing material from structure 120 is illustrated in an exemplary embodiment. Trimming station 140 may cut one side of structure 120, while another trimming station 140 simultaneously cuts the other side of structure 120. In this embodiment, structure 120 includes a semi-cylindrical section of the fuselage, which has been reinforced by stringers, frames, and window surrounds. Structure 120 includes a surface 312 in which excess manufacturing material 124 for window 314 has been removed (e.g., ...). Figure 1 The structure 120 also includes a window cutout 128 in the structure 120. The structure 120 also includes a transposition feature 126 (e.g., a hole, slot, RFID chip, etc.) disposed within the manufacturing excess portion 124.
[0065] Structure 120 is supported on track 110 at floor 360. Track 110 includes a first-height support 332 (also referred to herein as a "spring stilt"), and a second track 112 includes a second-height support 334, which allows structure 120 to move in the processing direction 199. Support 334 is higher than support 332 by the height of the manufacturing excess portion 124. That is, the spring stilt / support 334 located downstream of the trimming station 140 is higher than the spring stilt / support 332 located upstream of the trimming station 140. Although not depicted in the figures, in some exemplary examples, track 112 includes: supports 334, each including a support member holding structure 120 in place; and rollers that allow structure 120 to move in the processing direction 199 while being held by the support member.
[0066] During the advancement of structure 120, or during pauses between pulses of structure 120, individual workstations will transpose themselves to one or more transposition features 126, such as multiple transposition features 126, at the location of structure 120. This allows the workstations to determine their precise position relative to structure 120 and to characterize the structure 120 within the range of the workstation. Figure 1The portion 127 is depicted in the diagram. In this way, by referring to the indexing feature 126, the workstation can perform operations accurately and precisely at the structure 120.
[0067] The trimming station 140 includes a tool path 342 along which the cutter head 142 moves. In another embodiment, a stationary cutter performs the cutting step during the pulsating movement of the structure 120 in the processing direction 199. The pulsation can be performed at a frame pitch length or other distance, such that each cut portion is segmented at the end of the pulsation and falls into the chute 160. A pulsation equal to the length of the structure 120 is called a “full pulsation,” while a pulsation smaller than the length of the structure 120 (e.g., the frame pitch distance) is called a “micro pulsation.” The cutter head 142 advances back and forth by sliding along the tool path 342 in the processing direction 199. In some exemplary examples, movement in or parallel to the processing direction 199 is referred to as horizontal movement. In some exemplary examples, the cutter head 142 operates horizontally to remove manufacturing excess 124 from the structure 120. The cutter head 142 cuts the manufacturing residue 124 into multiple chips 150, which accumulate in the chute 160. After advancing through the trimming station 140, the structure 120 presents a final trimmed edge 129. The final trimmed edge 129 can provide the structure 120 with the desired dimensions for integration with another structure 120 (e.g., another section of the fuselage). That is, the final trimmed edge 129 can be trimmed to the final manufacturing dimensions. In one embodiment, during pauses in the advancement of the structure 120, multiple stations (e.g., for trimming, cleaning, non-destructive testing (NDI) inspection, and / or edge sealing) perform operations or otherwise operate on the structure 120 (e.g., at different portions 127 of its length).
[0068] Figure 4 This is the rear view of the trimming station 140, and... Figure 3 The view arrow 4 corresponds to this. Figure 4 The cutting station 140 includes a blade 400 protruding from the cutter head 142. The blade 400 is positioned at the desired height of the cut edge of the structure 120 being cut. Although in Figure 4 The blade 400 is exemplified as a reciprocating blade, but in other embodiments, the blade 400 includes a circular blade, a laser cutter, a pressurized waterjet cutter, or other cutting tools. Figure 4It is also shown that each support 332 includes a support 410 defining a groove for receiving the manufacturing excess portion 124 and a roller 420 for carrying the manufacturing excess portion 124. The structure conveyor 102 is a track 110, which includes supports 332, each support 332 including: a support 410 that holds the structure 120 in place; and a roller 420 that allows the structure 120 to move in the processing direction 199 while being held by the support. Although Figure 4 The track 110 is depicted with struts 332, but in some exemplary examples, the track 112 also includes struts 334, each strut 334 including: a support member that holds the structure 120 in place; and a roller that allows the structure 120 to move in the processing direction 199 while being held by the support member.
[0069] Figure 5 This is a perspective view of the edge-cutting station 140 in the exemplary embodiment, and is related to... Figure 4 The view arrow 5 corresponds to this. Figure 5 A frame 510 supporting the tool track 342 is illustrated, and a groove 520 is also illustrated, along which the tool head 142 slides at the tool track 342. Figure 5 A vacuum groove 550 at the cutter head 142 is also illustrated, which applies suction to remove dust and debris during cutting via the blade 400. Figure 5 The image also depicts a vertical cutter head 530. The vertical cutter head 530 is positioned downstream of the cutter head 142 and moves vertically upwards to cut the excess manufacturing portion 124 of the hanging amount into... Figure 1 The vertical cutter head 530 segments the manufacturing surplus 124 to be removed into chips 150 of predetermined lengths. The vertical cutter head 530 includes a blade 540 positioned below the edge of the manufacturing surplus 124 and advances vertically until it reaches the edge being cut by the cutter head 142. Thus, the vertical cutter head 530 applies a vertical cut to the manufacturing surplus 124 so that the manufacturing surplus 124 can be removed to a predetermined length. These vertical cuts can be applied before or after the operation of the cutter head 142. The cutter head 142 and the vertical cutter head 530 operate cooperatively (i.e., cutting segments without interfering with each other) to remove the manufacturing surplus 124.
[0070] Having discussed the specific implementation of the edge trimming station 140 above, Figure 6 This illustrates the arrangement of the trimming station 140 relative to other stations in the assembly environment. Specifically, Figure 6 This is a top view illustrating a series of stations that facilitate trimming, inspection, cleaning, and sealing in an exemplary embodiment. Figure 6In this process, structure 120 is pulsated along structure conveyor 102 (e.g., track 110) in processing direction 199. In the illustrated example, trimming station 140 may include a coarse trimming station 620 and a fine trimming station 630. Coarse trimming station 620 performs an initial cut within a first tolerance (e.g., 25 mm (tenth of an inch)) to remove manufacturing excess 124 from the side of structure 120. All coarse trimming can be completed in one station or even in a single pass of coarse trimming station 620. Fine trimming station 630 performs a fine cut to bring the edges to a predetermined tolerance (e.g., more stringent than the tolerance used for coarse trimming, such as within a 2.5 cm (1 inch) section). In some illustrated examples, the method includes operating fine trimming station 630 to cut off additional material from the edge of structure 120. In some exemplary examples, a fine-trimming station 630 operates to trim structure 120 to a final cut edge 129. A non-destructive testing (NDI) station 180 includes means for performing ultrasonic, laser, or visual inspection on the cut edge to detect delamination or other out-of-tolerance conditions. A cleaning station 660 removes dust and debris from structure 120, for example, by brushing, blowing, or rinsing with a liquid cleaning solution. The cleaning station 660 cleans the final cut edge 129. This can include operating elements 662 in the form of air knives, sprayers, brushes, etc. An example of an edge-sealing station 170 is illustrated as a chemical edge-sealing station 650. The cleaned portion of structure 120 reaches the chemical edge-sealing station 650, which seals the edges with a chemical sealant such as sealant 172. That is, the chemical edge-sealing station 650 seals the final cut edge 129 of structure 120. Other stations, such as a spraying station, may follow the stations discussed above.
[0071] Figure 7 This is a flowchart illustrating a method 700 for cleaning structure 120 in an exemplary embodiment, and the following is specifically for... Figure 8The method 700 includes advancing structure 120 along track 830 in a processing direction 199 in step 702. This can be performed continuously or in a pulsating manner. In some exemplary examples, advancing structure 120 along track 830 in the processing direction 199 includes pulsating structure 120 in the processing direction 199. In some exemplary examples, advancing structure 120 along track 830 in the processing direction 199 includes moving structure 120 continuously in the processing direction 199. The method 700 also includes aligning a cleaning station 660 at track 830 with an edge, such as a final cut edge 129 of structure 120 trimmed upstream of cleaning station 660, in step 704, and removing debris from the edge via cleaning station 660 in step 706. Debris removal may include applying fluid to the edge carrying debris from the edge, or may include brushing the edge. In one embodiment, cleaning station 660 removes debris from the entire contour of structure 120 (e.g., the entire cross-section, including the IML and / or OML) or within a threshold distance of the final cut edge 129 (e.g., within 2.5 cm (1 inch), 30.5 cm (12 inches), etc.). For example, cleaning station 660 may include annular clamps positioned at the IML and / or OML of structure 120, which scrub the entire structure 120 via brushes and / or jets. Debris removal may be performed via a large-scale application of pressurized air or pressurized liquid, and / or via abrasion with a scrubbing head. In step 708, structure 120 is further advanced along track 830 in the processing direction 199. In other embodiments, fluid is sprayed at an upstream angle (e.g., at 45 degrees into structure 120) so that dust does not accumulate downstream of cleaning station 660. The applied fluid may be captured via drain pipe 852.
[0072] In other embodiments, structure 120 is pulsed in the processing direction 199, and debris removal is performed during pauses between pulses or during the pulse. In other embodiments, structure 120 is continuously moved in the processing direction 199, and debris removal is performed as structure 120 continuously moves.
[0073] Figures 8 to 9 The illustration shows a cleaning station 660 at the edge of the cleaning structure in the exemplary embodiment. Figure 8 An exemplary embodiment illustrates a cleaning station 660 for cleaning the final cut edge 129 of a structure 120 having a contour 812 and a window cutout 128. The structure 120 is supported by its final cut edge 129 on a track 830 (e.g., ...). Figure 1On the additional or second track 112, track 830 includes a plurality of supports 334 at floor 360. During the advancement of structure 120 (e.g., during pulsations), or during pauses between pulsations of structure 120, cleaning station 660 transposes itself to one or more transposition features 126 at structure 120. This allows cleaning station 660 to determine its precise position relative to structure 120 and to characterize structure 120. In this way, by referring to transposition features 126, cleaning station 660 is able to perform work accurately and precisely at structure 120. In other embodiments, cleaning station 660 performs work based on transposition performed by an upstream station.
[0074] Figure 9 Corresponding to Figure 8 View arrow 9 illustrates that the cleaning station 660 includes a base 910 and a fork 920 supporting the cleaning head 930. The cleaning head 930 may include brushes for wiping edges (e.g., passive brushes, actively driven brushes, etc.), air knives that apply pressurized air to clean the final cut edge 129 with air, injectors / nozzles that apply fluids such as cleaning fluids to the edges, and any suitable combination thereof. Fluids such as pressurized air or liquids are drawn from a reservoir 950 and applied to the final cut edge 129. Excess fluid is captured and removed via a reservoir 940. Figure 10 Is with Figure 9 The 3D view of the cleaning station corresponding to arrow 10 in the view.
[0075] like Figures 8 to 10 As shown, the cleaning station 660 includes a track 830 that contacts and supports the final cut edge 129 of the structure 120, and allows the structure 120 to move in the processing direction 199. As the structure 120 advances in the processing direction 199 via the track 830, the cleaning station 660 removes debris from the final cut edge 129 of the structure 120.
[0076] Figure 11This is a flowchart illustrating a method 1100 for inspecting structure 120 in an exemplary embodiment. Step 1102 includes advancing structure 120 along track 112 in a processing direction 199. In some exemplary examples, advancing structure 120 along track 112 in the processing direction 199 includes pulsating structure 120 in the processing direction 199. In some exemplary examples, advancing structure 120 along track 112 in the processing direction 199 includes moving structure 120 continuously in the processing direction 199. During the advancement of structure 120 (e.g., during pulsation), or during pauses between pulsations of structure 120, nondestructive testing (NDI) station 180 and edge sealing station 170 independently and / or together rotate themselves to one or more rotation features 126 at structure 120. This allows the stations to determine their precise position relative to structure 120 and to characterize structure 120. In this way, by referencing the indexing feature 126, the workstation can perform the work accurately and precisely at structure 120. In other embodiments, the workstation performs the work based on an indexing performed by an upstream workstation. In other embodiments, other means are used to locate the edges of structure 120 (e.g., final cut edge 129 or bearing edge 125) of the structure 120 to which these workstations perform the work. Step 1104 includes aligning the nondestructive testing (NDI) workstation 180 at track 112 with the edge of structure 120 that was trimmed upstream of the NDI workstation 180. This can be performed via the indexing techniques discussed above. Step 1106 includes imaging the edge (e.g., final cut edge 129 or bearing edge 125) via the NDI workstation 180. This can include acquiring images via a camera, via an ultrasonic transducer, or via a laser. In one embodiment, imaging the edge includes applying ultrasonic energy to the edge. In other embodiments, imaging the edge includes acquiring a photographic image of the edge.
[0077] In embodiments using ultrasonic transducers, the image depicts the interior of structure 120 without damaging structure 120. Step 1108 includes characterizing edges based on the imaging. For example, a non-destructive testing (NDI) station 180 can characterize edges by identifying out-of-tolerance conditions at the edges. Step 1110 includes further advancing structure 120 in the processing direction 199.
[0078] In other embodiments, structure 120 is pulsed in the processing direction 199, and edge imaging is performed during pauses between pulses or during pulses. In other embodiments, structure 120 is continuously moved in the processing direction 199, and edge imaging is performed as structure 120 continuously moves.
[0079] Figures 12 to 13The non-destructive testing (NDI) station 180 for structural edges in the exemplary embodiment is shown. Figure 12 A non-destructive testing (NDI) station 180 for the final cut edge 129 of a characterizing structure 120 is illustrated in an exemplary embodiment. The structure 120 has a profile 1212 and a window surround 1214. The structure 120 is supported by its edges on a track 830, which includes a plurality of supports 334 at a floor 360. The track 830 contacts the final cut edge 129 of the structure 120 while simultaneously supporting the structure 120 from the final cut edge 129, and allows the structure 120 to move in the processing direction 199.
[0080] Figure 13 Corresponding to Figure 12 View arrow 13 illustrates a non-destructive testing (NDI) station 180 including sensors 1310 and 1320 (e.g., cameras, ultrasonic transducers that apply ultrasonic energy to the edge, lasers, etc.) that generate images of the final trimmed edge 129. A NDI controller 1330 characterizes the final trimmed edge 129 based on the images acquired by sensors 1310 and / or 1320. For example, the NDI controller 1330 can identify the presence of out-of-tolerance conditions at the final trimmed edge 129 based on the images. In these illustrative examples, the NDI station 180 includes an NDI controller 1330 that identifies out-of-tolerance conditions at the final trimmed edge 129 based on images acquired by the NDI station 180. The location of the edge sealing station 170 along the edge can be determined using input regarding the location and size of the out-of-tolerance condition. Figure 14 Is with Figure 13 The perspective view of the non-destructive testing (NDI) station (180) corresponding to arrow 14 in the view. Figure 14 As illustrated, sensors 1320 and 1310 may be accompanied by one or more rollers 1410 that support the final cut edge 129 as it advances.
[0081] Figure 15This is a flowchart illustrating a method 1500 for sealing the edge (e.g., final cut edge 129) of a sealing structure 120 in an exemplary embodiment. Step 1502 includes advancing the structure 120 along track 830 in a processing direction 199. During the advancement of the structure 120 (e.g., during pulsation), or during pauses between pulsations of the structure 120, a non-destructive testing (NDI) station (180) and an edge sealing station 170 independently and / or together rotate themselves to one or more rotation features 126 at the structure 120. In some exemplary examples, advancing track 830 in the processing direction 199 includes pulsating the structure 120 in the processing direction 199. In some exemplary examples, advancing the structure 120 along track 830 in the processing direction 199 includes continuously moving the structure 120 in the processing direction 199. This allows the workstations to determine their precise positions relative to structure 120 and to characterize portions 127 of structure 120 within the range of the workstation. In this way, by referencing the indexing feature 126, the workstations can perform work accurately and precisely at structure 120. In other embodiments, the workstations perform work based on indexing performed by upstream workstations. In other embodiments, other means are used to index the edges of structure 120 (e.g., final cut edge 129) operated on by these workstations. Step 1504 includes aligning the edge sealing workstation 170 at track 830 with the edge of structure 120 (e.g., final cut edge 129) trimmed upstream of the edge sealing workstation 170. This can be performed via the indexing techniques discussed above. Step 1506 includes applying an edge sealant 172 to the edge of structure 120 (e.g., final cut edge 129) via the edge sealing workstation 170. This can include rolling or spraying a liquid edge sealant 172, such as an epoxide, onto the edge, such that the edge sealant 172 fills any areas exceeding tolerances. In various implementations, the edge sealant 172 is applied by an automated device or manually during pulsation, during continuous propulsion, or during a period of stillness after pulsation.
[0082] Step 1508 includes further advancing structure 120 along track 830 in the processing direction 199.
[0083] In other embodiments, structure 120 is pulsed in the processing direction 199, and edge sealant 172 is applied during pauses between pulses or during pulses. In other embodiments, structure 120 is continuously moved in the processing direction 199, and edge sealant 172 is applied as structure 120 continuously moves. In other embodiments, edge sealant 172 is sprayed onto the edge of structure 120 (e.g., final cut edge 129). In other embodiments, applying edge sealant 172 prevents inconsistencies from propagating through the edge into structure 120. In other embodiments, applying edge sealant 172 includes applying an epoxide.
[0084] Figures 16 to 17 An edge sealing station 170 of the final cut edge 129 of the sealing structure 120 in the exemplary embodiment is shown. Figure 16 An edge sealing station 170 is illustrated in an exemplary embodiment, sealing the final cut edge 129 of a structure 120 having a contour 812 and a window surround 1214. The structure 120 is supported by its final cut edge 129 on a track 830 in the processing direction 199. The track 830 includes a plurality of supports 334 at a floor 360. The track 830 contacts the edge of the structure 120 while supporting it from the final cut edge 129, and allows the structure 120 to move in the processing direction 199. A heater 1652 at the edge sealing station 170 heats and cures the applied edge sealant 172 before the final cut edge 129 contacts / is supported by the next support 334.
[0085] Figure 17 Corresponding to Figure 16 View arrow 17 illustrates that the edge sealing station 170 includes an applicator 1710 (e.g., a sprayer / nozzle, a roller for applying edge sealant 172 from a reservoir, etc.) that applies edge sealant 172 (e.g., epoxide) from a reservoir 1730 to the final cut edge 129. A roller 1720 is also depicted, which is powered to facilitate the advancement of the structure 120.
[0086] Figure 18 It is the edge sealing station and Figure 17 The 3D view corresponding to view arrow 18. Figure 18 The applicator 1710 is depicted as being positioned on either side of the edge; however, in other embodiments, the applicator 1710 is positioned below the edge.
[0087] Now pay attention Figure 19 , Figure 19 The control components of a production system that performs ultrasonic inspection are extensively illustrated. Figure 19This is a block diagram of a control system for facilitating a mobile assembly line process, as illustrated in an exemplary embodiment. A controller 1900 coordinates and controls the operation of a trimmer cutter 1920 and the movement of one or more mobile platforms 1970 along a track 1960 having powered supports 1962. In one embodiment, the mobile platform 1970 includes multiple body sections having one or more bearing edges 1978 that contact the supports 1962. The controller 1900 may include a processor 1910 coupled to a memory 1912 storing a program 1914. In one example, the mobile platform 1970 is driven along the track 1960 (controlled by the controller 1900), which is continuously driven by the powered supports 1962.
