[0130] The following describes embodiments of the terminal crimping unit and the terminal crimping method.

[0131] Figure 1 This is a perspective view showing a terminal crimping unit according to an embodiment. Figure 2 It is shown Figure 1The diagram shows a schematic block diagram of the terminal crimping unit.

[0132] According to this embodiment, the terminal crimping unit 1 is, for example, an operating unit for manufacturing terminal-equipped wires W1 constituting a wire harness, which is installed and laid in vehicles or the like. In the terminal crimping unit 1, wires W12 of the required length for the wire harness are cut from a wire reel 111 stored in a wire storage section 11, and connector terminals W11 are crimped to both ends of the wires, thereby manufacturing terminal-equipped wires W1. The number of terminal-equipped wires W1 is the number required to manufacture one wire harness, and they are placed in a rod-shaped wire holder 241, with both ends held in a U-shaped bend. After all the terminal-equipped wires W1 have been placed, the operator Y1 removes the wire holder 241 containing the wires from the terminal crimping unit 1.

[0133] The terminal crimping unit 1 includes a wire storage section 11, a measuring section 12, a conveying section 13, a trimming section 14, an oiling section 15, a rubber plug insertion section 16, and a stripping section 17. Furthermore, the terminal crimping unit 1 includes a pre-crimping imaging section 18, a crimping section 19, a crimping confirmation section 21, a terminal rotation section 22, a selection and discarding section 23, a wire setting section 24, and a retainer moving section 25. The trimming section 14, oiling section 15, rubber plug insertion section 16, stripping section 17, and pre-crimping imaging section 18 are contained in a first unit 1a, and the crimping section 19 is contained in a second unit 1b. The crimping confirmation section 21, terminal rotation section 22, and selection and discarding section 23 are contained in a third unit 1c. The conveying section 13 connects the measuring section 12 and the wire setting section 24, and passes through the first unit 1a, the second unit 1b, and the third unit 1c. The various parts will now be described in conjunction with the accompanying drawings.

[0134] The wire storage section 11 is a storage rack for wire spools 111, and is used to store multiple wire spools 111, including wire spools of different thicknesses, etc. A wire spool for manufacturing a wire harness is selected from the multiple wire spools 111, and a wire is pulled out from each selected wire spool 111 and drawn into the measuring section 12 of the terminal crimping unit 1.

[0135] Figure 3 It is shown Figure 1 and Figure 2 A perspective view of the mechanical parts of the measuring unit shown. Figure 4 It shows how Figure 3 The diagram shown illustrates the wire harness being pulled out in a U-shaped bend in the measuring section.

[0136] The measuring unit 12 sequentially cuts portions of multiple wire harnesses W12 by repeatedly pulling out and cutting wires 111a of the required length from the wire reel 111. The measuring unit 12 cuts the wire harnesses W12 into a U-shaped bend and includes a wire pull-out mechanism 121 and a U-shaped bend steering mechanism 122. The wire pull-out mechanism 121 is a mechanical part that measures the pulled-out length while pulling the wires 111a out of the wire reel 111. The U-shaped bend steering mechanism 122 is a mechanical part that bends the wires 111a into a U-shape by rotating the end chuck 122a holding the pulled-out end 111a-1 of the wires 111a-1 in the rotation direction D11 by using a steering drive mechanism 122b. While the U-shaped bend steering mechanism 122 bends the wires 111a in this way, the wire pull-out mechanism 121 pulls out the wires 111a until the required length is reached. When the required length is reached, the cutting chuck 121a of the wire pulling mechanism 121 cuts the wire 111a and holds the cutting end, thereby cutting out a U-shaped wire harness W12. The cutting chuck 121a is located at a position 180 degrees in the rotation direction D11 relative to the rotated end chuck 122a. The wire harness W12 cut sequentially by the measuring unit 12, while maintaining the U-shaped bend, are sequentially transferred to the conveying unit 13 according to the cutting sequence.

[0137] Figure 5 It is shown Figure 1 and Figure 2 A schematic diagram of the conveyor section is shown.

[0138] The conveying unit 13 is a unit that sequentially receives the wire harness W12 from the measuring unit 12, holds its wire ends W121, and conveys it along a predetermined conveying path R11. As described above, the measuring unit 12 cuts out the wire harness W12 in a U-shaped bend. The conveying unit 13 receives the wire harness W12 in a U-shaped bend, holds its wire ends W121 at both ends, and conveys it in a U-shaped bend. The conveying unit 13 is equipped with a wire conveying chuck 131 and a wire conveying mechanism 132.

[0139] The wire transport chuck 131 is a mechanism that holds and removes the wire ends W121 from both ends of the wire harness W12 immediately after it is cut by the measuring section 12 and held by the end chuck 122a and the cutting chuck 121a, and transports it to the wire transport mechanism 132. The wire transport chuck 131 is equipped with: a pair of chuck sections 131a that hold both ends of the wire harness W12; and a chuck drive mechanism 131b that drives the pair of chuck sections 131a to reciprocate between the measuring section 12 and the wire transport mechanism 132.

[0140] The wire conveying mechanism 132 is the part that holds the ends of the wire harness W12 that are sequentially transported by the wire transport chuck 131 and conveys them to the wire setting section 24 along the transport path R11. The wire conveying mechanism 132 receives the wire harness W12 in a U-shaped bend from the wire transport chuck 131. Then, the wire conveying mechanism 132 holds the wire ends W121 at both ends of the U-shaped wire harness W12 and arranges them in a row along the transport path R11, thereby conveying the wire harness W12 in a U-shaped bend.

[0141] The conveying route R11 is a rectangular loop route, with its long side extending from the measuring unit 12 to the wire setting unit 24. The wire conveying mechanism 132 has a conveying track 132a, which is arranged above the rectangular loop conveying route R11 in the vertical direction D12 relative to the terminal crimping unit 1. The constituent elements from the measuring unit 12 to the wire setting unit 24 are arranged above the conveying track 132a along the upper side of the conveying route R11.

[0142] The wire conveying mechanism 132 is equipped with multiple conveying chucks 133 that move cyclically along the conveying path R11. These conveying chucks 133 are arranged in a row at equal intervals along the conveying path R11, and a pair of conveying chucks 133 move simultaneously while holding the wire ends W121 at both ends of a wire harness W12. When any one of the conveying chucks 133 reaches the wire setting section 24, it releases the wire ends W121, disengages from the conveying track 132a, and idles below the conveying track 132a back to the vicinity of the measuring section 12, before returning to the conveying track 132a. If there are still wire harnesses W12 to be conveyed, the conveying chuck 133 receives the wire ends W121 again from the wire conveying chuck 131 upon its return and moves along the conveying path R11.

[0143] While the wire harness W12, which is conveyed by the conveying unit 13, is being conveyed inside the first unit 1a, it undergoes a series of processes from the trimming unit 14 to the crimping pre-firing unit 18.

[0144] Figure 6 It is shown Figure 1 and Figure 2 The diagram shows a perspective view of the various mechanical parts inside the first unit, from the trimming section to the pre-pressing imaging section. Figure 7 It shows how to pass Figure 6 The diagram shows a series of processes performed on each part, from the trimming section to the pre-pressing imaging section.

[0145] The trimming unit 14 is located upstream of each section from the oiling unit 15 to the pre-crimping imaging unit 18 on the transport route R11, and performs the following trimming process on the wires W12 of the wire harness held by the transport chuck 133 and transported along the transport route R11. The trimming process is to trim the ends of the wire ends W121, which are transported in rows along the transport route R11, so that they are aligned with a predetermined end position P11. The trimming unit 14 includes a cutting mechanism 141 for trimming each end and a cutting drive mechanism 142 for driving the cutting mechanism 141. The cutting drive mechanism 142 moves the cutting blade 141a of the cutting mechanism 141 along the cutting direction D13 at the predetermined end position P11, thereby trimming the wire ends W121 to the end position P11. The trimmed wire ends W121 are then sent to the oiling unit 15.

[0146] The oiling section 15 is located upstream of the rubber plug insertion section 16 on the conveying route R11, and applies oil to the wires W12 of the wire harness that have not yet been inserted into the rubber plug.

[0147] Here, the wire storage section 11 stores various wire reels 111 of different thicknesses. For wires requiring rubber plugs (W13) to be inserted into the wire harness wires W12, the rubber plug insertion section 16 can insert various rubber plugs W13 of different aperture sizes into the wire end W121 of the wire harness wire W12. Depending on the combination of the wire reel 111 (i.e., the type of wire harness wire W12 from which it is cut) and the type of rubber plug W13 to be inserted, the friction between them may be significant, making it difficult to insert the rubber plug W13. In the oiling section 15, wires requiring rubber plugs that are difficult to insert are designated for lubrication with lubricating oil.

[0148] For a specified wire requiring lubrication, the oiling section 15 applies lubricant to the wire end W121 before the rubber plug insertion process. The oiling section 15 applies lubricant by clamping the wire end W121 with a pair of lubricating grippers 151. The oiling section 15 includes a pair of grippers 151 and an oiling drive mechanism 152, which drives one of the grippers 151 in the clamping direction D14 of the wire end W121. After this oiling process, the wire end W121 is fed to the rubber plug insertion section 16.

[0149] The rubber plug insertion section 16 is located upstream of the crimping section 19 on the transport route R11, specifically upstream of the stripping section 17, for rubber plug insertion processing. When a wire W12 for a wire harness, such as a waterproof connector, is designated to have a rubber plug W13 inserted, the rubber plug insertion process is performed. This process involves inserting the rubber plug W13 around the end W121 of the designated wire requiring the rubber plug. Among the wires requiring rubber plugs, those further designated as requiring lubrication are first lubricated and then subjected to the aforementioned lubrication treatment before undergoing the rubber plug insertion process. The rubber plug insertion section 16 for performing the rubber plug insertion process includes multiple insertion mechanisms 161 and an insertion drive mechanism 162. The multiple insertion mechanisms 161 are multiple mechanism parts that hold various types of rubber plugs W13 and insert them around the end W121 of the wire. The insertion drive mechanism 162 is a mechanism that drives each insertion mechanism 161 in the vertical direction D12 to the insertion position where the wire end W121 is to be inserted, and further drives each insertion mechanism 161 in the insertion direction D15 to insert the rubber plug W13 around the wire end W121. The wire ends W121 of wires requiring rubber plugs and wire ends W121 of wires requiring lubrication are sent to the stripping section 17 after being processed in the rubber plug insertion section 16. The wire ends W121 of other wire harness wires W12 are sent to the stripping section 17 without being lubricated or having rubber plugs inserted.

[0150] The stripping section 17 is located upstream of the crimping section 19 and downstream of the rubber plug insertion section 16 on the transport route R11. It strips the insulation from the wire harness wire W12 by removing the end cover W121b of the wire end W121 to expose the core wire W121a. The stripping section 17 is equipped with a pair of stripping blades 171 that clamp and cut off the end cover W121b, and a stripping drive mechanism 172 that drives the pair of stripping blades 171 in the stripping direction D16. After processing in the stripping section 17, the wire harness wire W12 undergoes pre-crimping imaging processing in the pre-crimping imaging section 18 at the same location.

[0151] The pre-crimping imaging unit 18 and the stripping unit 17 are located at the same position on the transport route R11. Before the crimping process in the crimping unit 19, the pre-crimping imaging unit 18 performs pre-crimping imaging on the wire harness W12 held by the transport chuck 133 and passing through the stripping unit 17. The pre-crimping imaging process is a process of acquiring a pre-crimping image G11 by photographing the end W121 of the wire, wherein the end cover W121b of the wire end W121 has been removed to expose the core wire W121a, and for a given wire, a rubber plug W13 has been inserted around the end W121 of the wire. The pre-crimping imaging unit 18 is equipped with a pre-crimping camera 181 for taking pictures and a pre-crimping image display unit 182 for displaying the pre-crimping image G11. The pre-crimping image G11 captured here is sent as image data to the crimping confirmation unit 21, and the determination unit 213 in the crimping confirmation unit 21, described below, determines whether the stripping criteria are met. The wire harness wire W12, whose end W121 has been photographed, leaves the first unit 1a and is sent to the second unit 1b. In the second unit 1b, the wire harness wire W12 is conveyed through the interior of the second unit 1b and crimped in the crimping part 19.

[0152] Figure 8 It is shown Figure 1 and Figure 2 The 3D diagram of the second unit is shown. Figure 9 It is shown Figure 8 A perspective view of the mechanical parts of the crimping section inside the second unit. Figure 10 It shows how to pass Figure 9 The diagram shows a series of processes performed on the crimping part.

[0153] The crimping section 19 is located downstream of the stripping section 17 on the transport path R11 and performs crimping processing on the wires W12 of the wire harness transported through the stripping section 17. The crimping section 19 includes: a terminal holding section 191 for holding various types of connector terminals W11 of different sizes in a pre-crimped unfolded state; and a plurality of crimping mechanisms 192, corresponding to the various types of connector terminals W11. Furthermore, the crimping section 19 includes a servo motor 193, which serves as a common drive source for the plurality of crimping mechanisms 192. The plurality of crimping mechanisms 192 are arranged in a row along the transport path R11. During the crimping process in the crimping section 19, the crimping mechanism 192 at the position where the wire end W12 corresponding to the type of connector terminal W11 to be crimped reaches is crimped. In this crimping process, the connector terminal W11 is crimped to the wire end W121 exposing the core wire W121a. At this time, for wires requiring rubber plugs, such as those with rubber plugs W13 around the insertion end W121, the connector terminal W11 is crimped through the rubber plug. Each crimping mechanism 192 includes an anvil 192a, a crimper 192b, and a clutch 192c as a drive transmission mechanism. The anvil 192a is the portion on which the connector terminal W13, in its unfolded state, is positioned with the wire end W121 placed on its upper surface. The crimper 192b is the portion that performs crimping by deforming the connector terminal W13 by clamping the connector terminal W13 and the wire end W121 between the anvil 192a and the crimper 192b. The clutch 192c transmits the driving force of the servo motor 193 to the crimper 192b. The crimper 192b, having received the driving force from the clutch 192c, descends towards the anvil 192a and performs crimping. After the processing in the crimping section 19 is completed, the wire harness W12 leaves the second unit 1b and is sent to the third unit 1c. While the wire harness W12 is being transported through the interior of the third unit 1c, it undergoes a series of processes from the crimping confirmation section 21 to the selection and discarding section 23.

[0154] Figure 11 yes Figure 1 and Figure 2 The third unit shown is a perspective view, in which part of the cover has been removed to show the parts from the crimping confirmation part to the selection and discarding part. Figure 12 It shows how to pass Figure 11 The diagram shows a series of processes performed on the crimping confirmation section and the terminal rotation section. Figure 13 It shows through Figure 11 The diagram shows the processing performed by the selection and discarding unit.

[0155] The crimping confirmation unit 21 is located downstream of the crimping unit 19 on the transport route R11, and is the part that performs crimping confirmation processing on the wire W12 of the wire harness transported through the crimping unit 19. In the crimping confirmation process, firstly, an image is taken of the wire end W121 with the connector terminal W11 crimped on. Then, based on the captured crimped image G12, it is determined whether a predetermined crimping standard is met. The crimping confirmation unit 21 includes: a crimping camera 211 for capturing images, a crimping image display unit 212 for displaying the crimped image G12, and a determination unit 213 for performing the determination process. When the crimped wire end W121, held and transported by the transport chuck 133, reaches directly below the crimping camera 211, the crimping camera 211 captures its image. The captured crimped image G12 is displayed on the crimping image display unit 212 and sent as image data to the determination unit 213. The determination unit 213 determines whether the crimping standard is met based on the crimped image G12 sent by the crimping camera 211. The determination result of the crimping standard, together with the determination result of the peeling standard based on the pre-crimping image G11 from the pre-crimping shooting unit 18, is sent to the selection and discarding unit 23.

[0156] The terminal rotation section 22 is located at an arbitrary given position downstream of the crimping confirmation section 21 on the transport route R11, specifically, the portion located between the crimping confirmation section 21 and the selection and discard section 23. This terminal rotation section 22 performs terminal rotation processing on the wires W12 of the wire harness transported via the crimping confirmation section 21 that require rotation. The wires requiring rotation are wires used in subsequent steps, such as inserting into a cavity in the connector housing, with a rotational orientation in which the connector terminal W11 rotates about the axis W11a of the connector terminal W11 during crimping from the crimping section 19. In the terminal rotation processing, the wires requiring rotation are specified, and the connector terminal W11 rotates about the axis W11a in the rotation direction D17. The terminal rotation section 22 includes a rotating chuck 221 and a rotation drive mechanism 222. When the wire end W121 of the wire requiring rotation is held and transported by the transport chuck 133, the rotating chuck 221 holds the portion of the wire end W121 adjacent to the connector terminal W11. The rotation drive mechanism 222 rotates the rotating chuck 221 holding the wire end W121 in the rotation direction D17 to perform the aforementioned terminal rotation process. In this embodiment, the rotation orientation of the wire to be rotated is a reverse orientation, in which the connector terminal W11 is reversed 180 degrees around the axis W11a from its orientation during crimping. The rotation drive mechanism 222 reverses the connector terminal W11 by rotating the rotating chuck 221 holding the wire end W121 180 degrees in the rotation direction D17.

[0157] The selection and discarding unit 23 is located downstream of the crimping confirmation unit 21 on the transport route R11, specifically downstream of the terminal rotation unit 22, and is used to select and discard the wires W12 of the wire harness that have been transported through the crimping confirmation unit 21 and the terminal rotation unit 22. In the selection and discarding process, wires W12 that are determined by the determination unit 123 to simultaneously meet both the stripping and crimping criteria are transferred from the transport unit 13 to the wire setting unit 24 as qualified wires W1 with terminals, where they undergo wire setting processing as a subsequent step. Conversely, wires W12 that are determined not to meet at least one of the stripping and crimping criteria are discarded as unqualified wires W1 with terminals. The selection and discarding unit 23 is equipped with a discarding mechanism 231, which takes out and picks up the wire ends W121 at both ends of the wires W1 with terminals attached to the defective parts from the transport chuck 133 and transports them to the discarding position 231a for discarding.

[0158] Figure 14 It is shown Figure 1 and Figure 2 A perspective view of the wiring installation section shown.

[0159] The wire setting section 24 is located downstream of the selection and discard section 23 on the transport route R11, that is, at the end of the transport route R11, and is the section used to perform wire setting processing on the wire harness wires W12 that meet the crimping criteria and are transported along the transport route R11. The wire harness wires W12 to be subjected to this wire setting processing are qualified wires W1 with terminals attached, which are transported in a U-shaped bent state with the connector terminals W11 crimped onto the wire ends W121 at both ends. During the wire setting processing, the wire ends W121 at both ends of the U-shaped wires W1 with terminals attached are taken out from the transport route R11 and transported to the rod-shaped wire holder 241 for holding.

[0160] The wire setting section 24 has two pairs of setting mechanisms 242, which remove the wire ends W121 at both ends of the wire W1 with terminals attached from the transport chuck 133 of the transport section 13 and transport them to the holding position within the wire holder 241, so that the wire holder 241 holds them. The rod-shaped wire holder 241 has a plurality of slits 241a arranged in a row along the length direction D18 of the rod, into which the wire bundle wire W12 of the wire W1 with terminals attached can be inserted. The pair of setting mechanisms 242 hold the wire ends W121 by inserting the wire ends W121 into a pair of slits 241a designated for each wire W1 with terminals attached. In this case, if the predetermined distance between the pair of slits 241a allows the pair of setting mechanisms 242 to be inserted side by side, the wire ends W121 at both ends of a wire W1 with terminals attached will be set simultaneously. In this embodiment, two pairs of setting mechanisms 242 are provided, allowing simultaneous setting of both ends of up to two wires W1 with terminals. Conversely, if the specified distance between a pair of slits 241a is too wide or too narrow, the setting of each wire end W121 will be performed individually by the corresponding setting mechanism 242. The wire setting unit 24 is equipped with a setting drive mechanism 243, which causes the two setting mechanisms 242 to reciprocate along the setting movement direction D19 between the transport chuck 133 and the slits 241a of the wire holder 241. This wire setting process by the wire setting unit 24 continues until all the wires W1 to be manufactured with terminals have been set in the wire holder 241. After the setting of all the wires W1 with terminals is completed, the holder moving unit 25 processes the wires in the wire holder 241 that hold the wires.

[0161] Figure 15 It is shown Figure 1 and Figure 2 A perspective view of the processing performed on the moving part of the retainer.

[0162] The retainer moving part 25 is positioned adjacent to the wire setting part 24. Then, the retainer moving part 25 performs a retainer moving process on the wire retainer 241, which has held all the processed wire harness wires W12, i.e., the wires W1 with terminals, which meet crimping standards and have undergone wire setting processing in the wire setting part 24. The retainer moving process involves moving the wire retainer 241 holding the wires to... Figure 1The processing of the junction position 251 is shown. Here, in the wire setting process in the wire setting section 24, the wire retainer 241 is oriented so that the slit 241a faces upward, allowing the setting mechanism 242 of the wire setting section 24 to enter from above and insert the wire end W121 into the slit 241a. Therefore, after the wire is set, the wire W1 with the terminal attached is held in a state where the wire end W121 is bent at 90° and hangs down to approach the slit 241a. In the retainer moving process, the retainer moving section 25 tilts the wire retainer 241 90° to the side in the tilting direction D20, so that the bend at the wire end W121 of each wire W1 with the terminal attached is eliminated and the wire hangs straight down to form a U-shape. In the retainer moving process, the wire retainer 241 slides to the junction position 251 in the junction direction D21 intersecting with the wire retainer 241 and is temporarily stored at the junction position 251.

[0163] Each time wire setting is performed in the wire setting section 24, the retainer is moved, and the wire retainers 241 holding multiple wires are stored parallel to each other in the handover position 251. The wire retainers 241 are removed from the handover position 251 by the operator at the appropriate time and transported to the unit where subsequent steps such as insertion into the cavity of the connector housing are performed.

[0164] Next, we will refer to the following. Figures 1 to 15 and Figure 16 The terminal crimping method performed in the terminal crimping unit 1 according to this embodiment is described, although some of the descriptions are repeated from those given so far.

[0165] Figure 16 It shows through Figures 1 to 15 The diagram shows a schematic flowchart of the terminal crimping method performed by the terminal crimping unit.

[0166] Figure 16The terminal crimping method shown in the flowchart begins when an operator inputs the part number of the article to be manufactured using an input device such as a personal computer (PC) and performs a predetermined start operation on the input device. When the process begins, the measuring unit 12 repeats the measurement process, which includes pulling out and cutting the wire 111a to the required length, thereby performing measurement step S101, in which multiple wire harnesses W12 are sequentially cut. Next, a conveying step S102 is performed, in which the wire harnesses W12 are held by the wire ends W121 at both ends and transferred along a predetermined conveying route R11 to the conveying unit 13 for conveying the wire harnesses W12, and the wire harnesses W12 are conveyed to the conveying unit 13. For the wire harnesses W12 that are designated as requiring rubber plugs and conveyed along the conveying route R11, a subsequent oiling step S103 and a rubber plug insertion step S104 are performed. In addition, for those wires that are further designated as requiring lubrication and require rubber plugs, an oiling step S103 is performed.

[0167] Before the rubber plug insertion step S104, in the oiling step S103, lubricating oil is applied to the wire end W121 of the specified wire that needs lubrication. In the rubber plug insertion step S104, the rubber plug W13 is inserted around the wire end W121 of the specified wire that needs the rubber plug.

[0168] Next, a stripping step S105 is performed, in which the end cover W121b of the wire end W121 of the wire harness wire W12 conveyed along the conveying route R11 is removed to expose the core wire W121a. Before the crimping step S107 described later, the wire end W121 of the wire harness wire W121 after the end cover W121b of the wire harness wire W121 has been removed in the stripping step S105 is photographed to obtain a pre-crimping image G11, and a pre-crimping confirmation step S106 is performed to determine whether the predetermined stripping criteria are met. In the crimping step S107 after the pre-crimping confirmation step S106, the connector terminal W11 is crimped to the wire end W121 of the wire harness wire W12 that has been conveyed through the stripping step S105 and the pre-crimping confirmation step S106, at which the core wire W121a of the wire harness wire W12 is exposed.

[0169] Next, a crimping confirmation step S108 is performed on the wire end W121, which has been crimped to the connector terminal W11 of the wire harness wire W12 delivered in crimping step S107. In crimping confirmation step S108, a crimped image G12 of the crimped wire end W121 is taken to determine whether it meets the predetermined crimping standard.

[0170] Following the crimping confirmation step S108, a terminal rotation step S109 is performed on the wire W12 of the wire harness, which has been conveyed through the crimping step S107 and is designated as a wire requiring rotation. The wire requiring rotation refers to a wire used in subsequent steps with a rotational orientation in which the connector terminal W11 rotates about axis W11a from its crimping orientation, and in the terminal rotation step S109, the connector terminal W11 of this wire requiring rotation rotates about axis W11a. As described above, in this embodiment, the connector terminal W11 rotates 180° from its crimping orientation about axis W11a.

[0171] In the subsequent selection and discarding step S110, the wire harness wire W12 that was determined to meet the stripping standard in the pre-crimping confirmation step S106 and the crimping standard in the crimping confirmation step S108 is handed over as a qualified wire W1 with terminals to the subsequent steps. Conversely, the wire harness wire W12 that does not meet at least one of the stripping and crimping standards is discarded as an unqualified wire W1 with terminals. Then, for the wire W1 with terminals that was determined to be qualified in the selection and discarding step S110, the wire setting step S111 is performed, in which the wire end W121 with the connector terminal W11 crimped is taken out from the transport route R11 and transported to and held in the rod-shaped wire holder 241.

[0172] After the wire setting step S111, a determination step S112 is performed to determine whether the setting of a group of wires W1 with terminals to be manufactured in the wire holder 241 has been completed. If the setting of a group has not been completed (determined as "No"), the determination step S112 is repeated once each time a wire W1 with terminals is set in the wire setting step S111. Then, if the setting of a group has been completed (determined as "Yes"), the holder moving step S113 is performed to move the wire holder 241 holding the wires to the handover position 251.

[0173] After the retainer movement step S113, a second determination step S114 is performed to determine whether to continue placing the wire W1 with the terminal attached onto the new wire retainer 241. If it continues to be placed onto the wire retainer 241 (determined as "yes"), the process returns to the measurement step S101 and the subsequent processing is repeated. Conversely, if it is not necessary to place it onto the wire retainer 241 (determined as "no"), the terminal crimping method process is terminated.

[0174] The terminal crimping unit 1 and terminal crimping method according to the above embodiments provide the following effects. Specifically, according to this embodiment, the wire W12 for the wire harness is sequentially cut out and conveyed along a predetermined conveying route R11. Subsequently, along the conveying route R11, a series of processes are smoothly carried out, including stripping the insulation from the wire end W121, crimping the connector terminal W11, crimping confirmation, and selecting and discarding defective parts. In this way, according to this embodiment, the connector terminal W11 can be crimped onto the wire W12 for the wire harness while reducing the various burdens on the operator Y1.

[0175] In this embodiment, the measuring unit 12 cuts out a U-shaped wire harness W12, and the conveying unit 13 receives the wire harness W12 from the measuring unit 12 while it is in a U-shaped bend. The conveying unit 13 arranges the wire ends W121 along the conveying path R11 while maintaining them at both ends of the wire harness W12, thus conveying the wire harness W12 while it is in a U-shaped bend. With this structure, the terminals of the wire ends W121 at both ends can be crimped sequentially without changing the direction of the wire harness W12, further reducing the workload of the operator Y1.

[0176] Furthermore, in this embodiment, a trimming section 14 for trimming and aligning the ends of the wire ends W121 is provided upstream of the stripping section 17 on the transport path R11. According to this configuration, the ends of the wire ends W121 of the wire harness wire W12 transported along the transport path R11 are trimmed and aligned, thereby improving the accuracy of the terminal crimping.

[0177] Furthermore, in this embodiment, the crimping confirmation unit 21 includes a crimping image display unit 212 that displays the crimped image G12. This configuration is preferred because it allows the operator Y1 to visually grasp the crimped image G12 through the crimping image display unit 212.

[0178] Furthermore, in this embodiment, the pre-crimping imaging unit 18 is located at the same position as the stripping unit 17 on the transport route R11. This pre-crimping imaging unit 18 acquires a pre-crimping image G11 by photographing the wire end W121, whose end coating W121b has been removed before the crimping process. Then, based on this pre-crimping image G11, it is determined whether the stripping criterion is met. According to this configuration, the crimping confirmation process is performed based on the stripping state of the wire end W121 shown in the pre-crimping image G11, thereby improving confirmation accuracy. In this embodiment, the stripping criterion determination is performed in the determination unit 213 of the crimping confirmation unit 21, which receives the pre-crimping image G11 from the pre-crimping imaging unit 18. However, the part used to determine the stripping criterion is not limited to this, and a dedicated determination unit independent of the determination unit 213 of the crimping confirmation unit 21 may also be provided to determine the stripping criterion.

[0179] Furthermore, in this embodiment, the pre-crimping imaging unit 18 has a pre-crimping image display unit 182 that displays the pre-crimping image G11. This configuration is preferred because it allows the operator Y1 to visually grasp the pre-crimping image G11 through the pre-crimping image display unit 182.

[0180] Furthermore, in this embodiment, the rubber plug insertion part 16 is provided upstream of the crimping part 19 on the transport route R11 to insert the rubber plug W13 around the wire end W121 of the designated wire requiring the rubber plug. For the wire requiring the rubber plug, the crimping part 19 performs the process of crimping the connector terminal W11 through the rubber plug. According to this configuration, the rubber plug insertion process for the wire requiring the rubber plug and the subsequent crimping process through the rubber plug are combined into a series of processes after measurement, thereby further reducing the burden on the operator Y1.

[0181] Furthermore, in this embodiment, the oiling section 15 is provided upstream of the rubber plug insertion section 16 on the transport route R11 to apply lubricating oil to the end W121 of the wire that requires lubrication before the rubber plug insertion process. With this configuration, even if the rubber plug W13 is difficult to insert due to the thickness of the wire W12 or other factors, the oiling process in the oiling section 15 can ensure smooth rubber plug insertion.

[0182] Furthermore, in this embodiment, the wire setting section 24 is located downstream of the selection and discarding section 23 on the transport route R11 to remove the wire ends W121 of the wire harness wires W12 that meet the crimping standard from the transport route R11 and transport them to the wire holder 241 so that the wire holder 241 holds them. According to this structure, the wire harness wires W12 with connected terminals are sequentially placed in the wire holder 241. The operator Y1 only needs to transport the wire holder 241 to the next operating position, which further reduces the burden on the operator Y1 compared to the case where the operator Y1 removes the wire harness wires W12 with connected terminals one by one from the transport route R11 and transports them individually.

[0183] Furthermore, in this embodiment, the wire setting unit 24 simultaneously or sequentially removes the wire ends W121 at both ends of the U-shaped wire harness W12 from the transport route R11 and transports them to the wire holder 241, whereby the wire holder 241 holds them. In this way, the wire setting unit 24 holds the U-shaped wire harness W12 in the wire holder 241. According to this structure, by setting the wire ends W121 at both ends of the wire harness W12 in the wire holder 241, the ease of operation in subsequent steps of removing the wire harness W12 from the wire holder 241 and processing each wire end W121 can be improved.

[0184] Furthermore, in this embodiment, a retainer moving part 25 is provided to move the wire retainer 241 holding the wire to a predetermined handover position 251. This structure improves the ease of operation for the operator Y1 to remove the wire retainer 241 for subsequent steps.

[0185] Furthermore, in this embodiment, a terminal rotating part 22 is provided downstream of the crimping confirmation part 21 on the transport path R11. This terminal rotating part 22 causes the connector terminal W11 of a specific wire that needs to be rotated to rotate around the axis W11a. According to this structure, the terminal rotation process can be performed according to the processing status of the wire end W121 in subsequent steps, thereby improving the operational convenience in subsequent steps.

[0186] The above embodiments only show representative forms of the terminal crimping unit and terminal crimping method. The terminal crimping unit and terminal crimping method are not limited to these and can be modified in various ways.

[0187] For example, in the above embodiments, as examples of terminal crimping units and terminal crimping methods, a terminal crimping unit 1 and a terminal crimping method for manufacturing a terminal-equipped wire W1 constituting a wire harness installed and laid in vehicles, etc., are shown. However, the terminal crimping unit and terminal crimping method are not limited thereto, and their applications are not particularly limited.

[0188] Furthermore, in the above embodiments, as examples of terminal crimping units and terminal crimping methods, the specific shapes and arrangements of their constituent elements are shown as follows: Figure 1 and Figure 2 The terminal crimping unit 1 and the terminal crimping method using the terminal crimping unit 1 are shown. However, the terminal crimping unit and the terminal crimping method are not limited thereto, and the specific shape and arrangement of the constituent elements of the terminal crimping unit are not particularly limited.

[0189] Furthermore, in the above embodiments, as examples of terminal crimping units and methods, a terminal crimping unit 1 and a terminal crimping method are shown in which a wire holder 241 for holding a wire is removed by an operator Y1 and transported to a unit for subsequent processing steps. In this embodiment, a qualified wire W1 with terminals is handed over to a wire setting part 24 and placed in a rod-shaped wire holder 241. However, the terminal crimping unit and terminal crimping method are not limited to this. The terminal crimping unit and terminal crimping method may be a unit or method that does not involve handing over a wire to a wire setting part 24, placing it in a wire holder 241, or transporting the wire holder 241 by an operator Y1. In such units and methods, the wire with terminals is directly handed over to a unit for subsequent processing steps, such as a terminal insertion unit, and the terminal insertion unit performs processing such as terminal insertion.

[0190] Furthermore, in the above embodiments, as examples of the terminal rotation part and the terminal rotation step, the terminal rotation part 22 and the terminal rotation step S109 are shown, wherein the connector terminal W11 is reversed from its orientation during crimping to an orientation that rotates 180 degrees around the axis W11a. However, the terminal rotation part and the terminal rotation step are not limited to this, and the connector terminal can rotate any rotation angle around the axis from its orientation during crimping.
