As shown in FIG. 5, the electric wire feeder 10 sends the electric wire 3 to be crimped to the terminal 90 in the arrow X direction. The electric wire 3 is a covered electric wire in which a conductor portion 3b, which is a conductive core wire, is covered with an insulating covering portion 3a. The electric wire 3 is stripped in the process before point A and is exposed at the end portion. Is exposed. One end side and the other end side of the electric wire 3 are clamped by two adjacent moving mechanisms 13 out of a plurality of moving mechanisms 13 that sandwich the electric wire 3 and send it in the arrow X direction at a predetermined pitch.

As shown in FIG. 6, the electric wire feeding part 10, the extraction part 20, the terminal transfer part 30, and the crimping part 50 are each connected to the calculation part 5. The calculation unit 5 is a CPU (Central Processing Unit) mounted on a substrate (not shown), for example, and executes various types of calculation processing to perform the wire feeding unit 10, the takeout unit 20, the terminal transfer unit 30, and the crimping unit. 50 controls each operation. Below, the structure of the extraction part 20, the terminal transfer part 30, and the crimping | compression-bonding part 50 among these is demonstrated in order.

<Extraction department, extraction process>
The extraction part 20 is arrange | positioned in the back side in the terminal crimping electric wire manufacturing apparatus 1, as shown in FIG. As shown in FIGS. 7 and 8, the take-out unit 20 includes a plurality of storage boxes 22 that are arranged in an annular shape and each receive a terminal 90 having a different product number, and an arithmetic unit that supports the plurality of storage boxes 22. The terminal 90 is taken out of the support box 21 rotating according to the instruction 5 and the storage box 22 located at the predetermined take-out position S among the plurality of storage boxes 22 and placed on the mounting surface 81 of the mounting table 80. The moving unit 23 is included as a main component. The support base 21 is disposed at a position indicated by a broken line in FIG. In each drawing other than FIG. 8, the support base 21 is omitted in order to facilitate grasping of the structure.

The moving unit 23 includes a take-out robot 26 composed of a robot arm having a plurality of joints, and a suction unit 27 provided at the tip of the take-out robot for sucking and fixing the terminal 90 by negative pressure suction. When an electric motor (not shown) provided at each joint of the take-out robot 26 is driven by an instruction from the calculation unit 5, each arm of the take-out robot 26 is displaced, and thereby the suction unit 27 moves. In the present embodiment, the suction portion 27 is configured to be movable at least between the take-out position S and a predetermined detachment position U located above the placement surface 81. In FIG. 9, the suction part 27 located at the take-out position is indicated by a solid line, and the suction part 27 located at the detachment position U is indicated by a broken line. The suction portion 27 has an air inlet (not shown) formed at the tip thereof, and sucks the terminal 90 accommodated in the housing box 22 by sucking negative pressure at the air inlet. The intake port is formed to be relatively large with respect to the shape of the terminal 90, whereby the suction portion 27 can suck the plurality of terminals 90. The suction portion 27 descends from the take-out position S to a position where it contacts the terminal 90 in the storage box 22 and sucks some of the terminals 90 among the terminals 90 stored in the storage box 22, and then the removal position. It moves to U, the terminal 90 is removed from the attachment position U, and the terminal 90 is placed on the placement surface 81. That is, the take-out unit 20 is configured to take out two or more terminals 90 of the selected product number and place them on the placement surface 81. As described above, in the take-out unit 20, the terminal 90 is taken out from the storage box 22 and placed on the placement surface 81.

The take-out unit 20 having the above configuration has a function of taking out a terminal 90 of a product number selected to be crimped from a plurality of product numbers and placing it on the mounting table 80. More specifically, first, the arithmetic unit 5 controls a support base drive unit (not shown) that drives the support base 21, and the product number selected to perform the crimping among the plurality of storage boxes 22. The support base 21 is rotated so that the storage box 22 storing the terminal 90 is positioned at the take-out position S. Thereafter, the calculation unit 5 controls the electric motor, moves the take-out robot 26, and positions the suction unit 27 at the take-out position S. Then, the calculation unit 5 causes the adsorption unit 27 to adsorb the terminal 90, moves the adsorption unit 27 to the attachment / detachment position U, and causes the terminal 90 to attach / detach at the attachment / detachment position U.

By executing these processes, in the take-out process by the take-out unit 20, a plurality of terminals 90 of the product number selected to be crimped from among a plurality of product numbers are taken out from the storage box 22 and are placed on the mounting table 80. It is mounted on the mounting surface 81. When supplying terminals 90 having different product numbers, different storage boxes 22 corresponding to the terminals 90 having different product numbers are positioned at the extraction position S. As a result, the terminals 90 with different product numbers are fixedly moved by the suction unit 27 (moving unit 23), so that the terminals 90 with different product numbers can be supplied onto the placement surface 81. Even when the terminals 90 having different product numbers are supplied from different storage boxes 22, the take-out position S and the detachment position U are the same.

Thus, according to the extraction process by the extraction unit 20, switching to a different product number can be handled only by switching the storage box 22 by rotation of the support base 21, so that the switching time can be shortened. In addition, since the support box 21 rotates, the storage box 22 that stores the terminal 90 of the selected product number is positioned at the take-out position S, so that it is selected from among a plurality of storage boxes 22 that are fixed and arranged, for example. Compared to the case where the moving unit 23 moves to the arrangement position of the storage box and takes out the terminal 90, the moving distance of the moving unit 23 is short, and the moving time is short if the moving speed is the same. For this reason, the processing speed of a manufacturing apparatus can be improved.

The specified mounting posture of the terminal 90 is also used for correcting the posture of the terminal 90 when the terminal 90 is transferred to the delivery position R2. Details of these processes will be described later.
Below, the structure of each part with which the terminal transfer part 30 is provided is demonstrated first.

In the present embodiment, the photographing unit 33 and the fixing unit 35 are configured to be movable at least between the entire upper surface of the placement surface 81 and the delivery position R2 illustrated in FIG.

The imaging unit 33 is, for example, a camera, and is attached to the tip of the terminal transfer robot 32 so as to face downward. The photographing unit 33 is used for photographing the terminal 90 placed on the placement surface 81 and acquiring an image obtained by photographing the terminal 90. The image acquired by the imaging unit 33 is used to detect the outer edge shape of the terminal 90 placed on the placement surface 81 on the detection plane parallel to the placement surface 81. In the present embodiment, an illuminating device (not shown) is provided inside the mounting table 80 disposed between the extraction unit 20 and the terminal transfer unit 30, and illumination emitted from the illuminating device. An illumination region 83 that is illuminated from below is defined in a predetermined region of the mounting surface 81 that is the upper surface of the mounting table 80 by light. Therefore, if the terminal 90 placed on the illumination area 83 is photographed from above by the photographing unit 33, the illumination light functions as a backlight, and the outer edge on the detection plane parallel to the placement surface 81 of the terminal 90 An image with an emphasized shape can be acquired (detection step). As described above, in the present embodiment, a binarized image representing the shadow of the terminal as shown in FIG. 10 is acquired using the photographing unit 33 and the illumination device, and the terminal 90 is mounted using the image. Specify the posture.

claws

35a and 35a, and the terminal 90 can be fixed by sandwiching the terminal 90 therebetween. The fixing portion 35 is used for fixing the terminal 90 placed on the placement surface 81. Further, as will be described later, the fixing claw 35a of the fixing portion 35 is configured to be rotatable in the F direction orthogonal to the arrow D in FIG. In this embodiment, as shown in FIGS. 11 and 12, the fixing portion 35 fixes the terminal 90 so that the connection portion 91 of the terminal 90 is located on the outer side.

In the second state where one of the caulking pieces 95a faces (the state of the terminal 90b in FIGS. 9 to 11), the other caulking piece 95b of the pair of caulking pieces 95 is placed on the mounting surface 81. A third state facing (the state of the terminal 90c in FIGS. 9 to 11) and a fourth state (the state of the terminal 90d in FIGS. 9 to 11) where the tip of the crimping piece 95 faces the mounting surface 81. ) And 4 states (mounting postures). The fixing portion 35 is configured to fix the terminal 90 placed on the placement surface 81 in each of these states.

A method for identifying these four states will be described.
First, in the second state of the terminal 90b and the third state of the terminal 90c, these images in the image acquired by photographing the terminal 90 placed on the placement surface 81 are the terminals 90 in other states. Since the outer edge shape is different from that of the image, it can be identified. Note that the image of the terminal 90 in the second state and the image of the terminal 90 in the third state are inverted in the front-rear direction of the terminal 90.

On the other hand, it is difficult to identify the first state of the terminal 90a and the fourth state of the terminal 90d based on the outer edge shape in the acquired image, and there is a risk of erroneous determination. For this reason, in this embodiment, the terminal 90 is placed on the placement surface 81 in any of the unconfirmed state, the second state, and the third state, which are the first state and the fourth state. Whether it is placed is identified based on the outer edge shape of the terminal 90 in the detection plane.

By the way, even if the fixing unit 35 cannot recognize before the terminal 90 is fixed whether the terminal 90 is mounted on the mounting surface 81 in the first state to the fourth state. Since it is possible to specify the fixed portion from the shadow of 90, the terminal 90 can be fixed by the fixing portion 35. Therefore, in the present embodiment, when the terminal 90 is identified as the indeterminate state, the terminal 90 is fixed to the placement surface 81 by performing a predetermined identification process after the terminal 90 is fixed by the fixing unit 35. It is discriminated whether it was placed in the state 4 or 4th state.

More specifically, the terminal transfer part 30 further includes a contact part 37 provided so as to be movable in the vicinity of the fixed part 35. The contact portion 37 is formed in a plate shape as shown in FIG. Further, the contact portion 37 is configured to be movable in the direction D in FIG. 12, which is a predetermined contact direction, and is configured to be rotatable in the direction E in FIG. 12, which is also the predetermined contact direction. . Thereby, the contact portion 37 is at least a predetermined contact position shown in FIG. 12 and a predetermined standby position (after rotating in the negative direction in the E direction from the position shown in FIG. 12, parallel to the negative direction in the D direction). It can move to and from the moved position.) As shown in FIG. 13, when the contact portion 37 moves in the contact direction from the standby position toward the contact position (that is, after moving in parallel in the positive direction in the D direction and then rotating in the positive direction in the E direction). In the case where the terminal 90 is fixed in the first state and in the case where the terminal 90 is fixed in the fourth state, the terminal 90 is in contact with the terminal 90 fixed to the fixing portion 35 at different positions. To do. That is, when the terminal 90 is fixed in the first state and the base portion 93 is positioned on the distal end side of the fixing claw 35a as shown in FIG. 13A, the terminal 90 is fixed in the fourth state. As shown in FIG. 13B, the contact portion 37 is connected to the terminal 90 at a different position when the base portion 93 is located closer to the base end side of the fixing claw 35a than the position shown in FIG. Contact. For this reason, if the contact part 37 is moved in the contact direction from the standby position after the terminal 90 placed in the unconfirmed state is fixed to the fixing part 35, the contact part 37 is based on the position where the contact part 37 contacts the terminal 90. Thus, it is possible to specify whether the terminal 90 is placed on the placement surface 81 in either the first state or the fourth state.

According to the procedure described above, in this embodiment, it is possible to identify whether the terminal 90 is placed on the placement surface 81 in the first state to the fourth state.

In the present embodiment, as described above, a plurality of terminal 90 having a product number selected to be crimped from a plurality of product numbers are taken out from the storage box 22 by the suction portion 27 in the take-out process. It is mounted on the mounting surface 81 of the mounting table 80. At this time, the adsorbing portion 27 detaches and drops the plurality of terminals 90 above the placement surface 81, so that, on the placement surface 81, in addition to the first to fourth states, FIG. In some cases, there are terminals 98 that overlap each other. If the overlapping terminals 98 are clamped by the fixing claws 35a of the fixing portion 35 to be fixed, there is a possibility that fixing will be lost or the fixing position or fixing posture may be shifted from a desired position. In this regard, according to the image acquired by the photographing unit 33, as shown in FIG. 10, the terminals 90 overlapping each other can be identified from the terminals 90 in other states. For this reason, in the terminal crimping electric wire manufacturing apparatus 1 according to the second embodiment, one that overlaps each other from among the plurality of terminals 90 placed on the placement surface 81 based on the image acquired by the imaging unit 33. And one terminal 90 selected from those other than the overlapping ones is fixed to the fixing unit 35. For this reason, since the overlapping terminal 98 is not fixed by the fixing portion 35, the terminal 90 can be fixed by the fixing portion 35 with high accuracy and reliability.

Next, the terminal transfer process by the terminal transfer unit 30 will be described. Before carrying out the terminal transfer step, the above-described take-out step is carried out, and a plurality of terminals 90 of a product number selected to be crimped from a plurality of product numbers are placed on the placement surface 81. Has been.

In the terminal transfer process, the arithmetic unit 5 first controls the electric motor of the terminal transfer robot 32 to displace the terminal transfer robot 32, and the photographing unit 33 is placed on the placement surface 81 (illumination region 83) as shown in FIG. Move to the top). And the calculating part 5 controls the imaging | photography part 33 and an illuminating device, and acquires the image which image | photographed the terminal 90 mounted on the mounting surface 81 from upper direction (detection process). The computing unit 5 is in any one of the unconfirmed state, the second state, the third state, and the overlapping state, which are the first state or the fourth state, according to the determination criteria described above. Whether the terminal 90 is placed on the placement surface 81 is identified based on the outer edge shape of the terminal 90 on a detection plane parallel to the placement surface 81. As a result of the identification, the calculation unit 5 identifies one terminal 90 selected from the terminals other than the overlapping terminals 98 as the terminal 90 to be fixed to the fixing unit 35. The selected terminal 90 may be any terminal 90 among the terminals 90 other than the overlapping terminal 98. The computing unit 5 again controls the electric motor of the terminal transfer robot 32 to displace the terminal transfer robot 32 and moves the fixing unit 35 to the position of the specified terminal 90. The calculating part 5 fixes the terminal 90 to the fixing | fixed part 35 by pinching with the fixing nail | claw 35a. As a result of the identification, the calculation unit 5 identifies that the terminal 90 is placed in an indeterminate state, and the fixing unit 35 fixes the terminal 90 placed in the indeterminate state. In this case, after the fixing, the contact portion 37 is moved from the standby position in the contact direction, and based on the position where the contact portion 37 contacts the terminal 90 at this time, either state of the first state or the fourth state Thus, it is identified whether the terminal 90 has been placed on the placement surface 81 (identification step).

Further, in the present embodiment, when the calculation unit 5 determines from the image acquired from the imaging unit 33 that a defect has occurred in the terminal 90 or the extraction unit 20 has failed to extract the terminal 90. Notifies the abnormality by voice or the like. Alternatively, the terminal 90 in which an abnormality has occurred is removed from the placement surface 81. Or the drive of the terminal crimping electric wire manufacturing apparatus 1 is stopped. For example, when a terminal 90 having a product number different from the selected product number is accidentally placed on the placement surface 81, or when the terminal 90 is not placed on the placement surface 81 at all, and A case where the placed terminal 90 is damaged or deformed can be identified from the image acquired by the photographing unit 33. That is, in the conventional crimping apparatus, after crimping, there is no choice but to check whether or not the crimping has been normally performed, whereas according to the terminal crimping electric wire manufacturing apparatus 1 according to the second embodiment, crimping is performed. Since it can be detected whether the terminal 90 was normally supplied before, the quality of the terminal crimping electric wire which is a product can be improved.

Through the processing described above, the calculation unit 5 grasps whether the terminal 90 fixed by the fixing unit 35 is placed on the placement surface 81 in the first state to the fourth state. . And the calculating part 5 controls the electric motor of the terminal transfer robot 32, and displaces the terminal transfer robot 32, and the fixed part 35 is a delivery position of the terminal 90 with the crimping | compression-bonding part 50, as shown in FIG. Move to delivery position R2. As shown in FIG. 14, the calculation unit 5 turns the terminal transfer robot 32 to transfer the fixed unit 35 (terminal 90) to the vicinity of the delivery position R2. At this time, the calculation unit 5 controls the displacement of the terminal transfer robot 32 to position the terminal 90 fixed to the fixing unit 35 at the delivery position R2 and rotate the fixing claw 35a in the direction F in FIG. , The posture of the terminal 90 in the F direction is corrected. For example, when it is necessary to position the terminal 90 at the delivery position R2 in the posture shown in FIG. 12 with the terminal 90 fixed in the first state, the terminal 90 is fixed in the second state and the third state. In this case, the attitude of the terminal 90 is corrected by rotating the fixed claw 35a by 90 ° in the positive or negative direction in the F direction. When the terminal 90 is fixed in the fourth state, the fixing claw 35a is rotated 180 ° to correct the attitude of the terminal 90. Thereby, the terminal 90 fixed to the fixing | fixed part 35 is positioned by the delivery position R2 with a desired attitude | position. At this time, in addition to or in place of the rotation of the fixing portion 35, the posture of the terminal 90 fixed to the fixing portion 35 by the mechanism of the terminal transfer robot 32 may be corrected.

As described above, in the terminal transfer step by the terminal transfer unit 30, the terminal 90 placed on the placement surface 81 in the take-out step is fixed by the fixing unit 35 and transferred to a predetermined delivery position R2. This terminal transfer process is repeatedly performed until, for example, the terminal 90 disappears on the placement surface 81. Note that the terminals 90 determined to overlap each other on the placement surface 81 are removed from the placement surface 81 at a predetermined timing. In addition, the terminal transfer process and the extraction process are repeatedly performed, whereby a terminal 90 having a product number selected from a plurality of product numbers is placed on the placement surface 81 by the take-out unit 20, and the terminal 90 is It is transferred to the delivery position R <b> 2 by the terminal transfer unit 30 and supplied to the crimping unit 50.

According to the terminal transfer unit 30, the terminal 90 is fixed by the fixing unit 35 after grasping the outer edge shape of the terminal 90 mounted on the mounting surface 81 on the detection plane, so that the terminal 90 is mounted on the mounting surface 81. The placed terminal 90 can be securely fixed. That is, since the outer edge shape of the terminal 90 is grasped, even if the terminal 90 is irregularly placed on the placement surface 81, the placement position of the terminal 90 is specified and fixed. The portion 35 can be securely fixed. For this reason, the extraction part 20 does not necessarily need to position and mount the terminal 90 at a predetermined position on the mounting surface 81. Therefore, the extraction unit 20 can be realized with a simple structure.

Moreover, the terminal crimping electric wire manufacturing apparatus 1 according to the second embodiment described above can be regarded as a wire harness component transfer apparatus. That is, the terminal crimped electric wire manufacturing apparatus 1 fixes the terminal 90 to the photographing unit 33 (detection unit) that acquires information for detecting the terminal 90 (wire harness component) placed on the placement surface 81. A terminal transfer unit 30 (transfer unit) for fixing the terminal 90 placed on the placement surface 81 to the predetermined delivery position R2 and fixing the terminal 90 placed on the placement surface 81 to the predetermined delivery position R2. A storage unit (arithmetic unit 5) for storing unique information and an arithmetic unit 5 connected to the photographing unit 33 and the terminal transfer unit 30 are provided. Then, the calculation unit 5 recognizes the grip position of the terminal 90 placed on the placement surface 81 based on the information acquired by the photographing unit 33, and fixes the terminal 90 to the fixing unit 35 at the grip position. To the delivery position R2.
Further, the calculation unit 5 recognizes the position and orientation of the terminal 90 (wire harness component) placed on the placement surface 81 based on the information acquired by the imaging unit 33 (detection unit), and recognizes the recognized position and The grip position of the wire harness component is recognized based on the posture.

The part 67, the first anvil part 68, and the second anvil part 69) are set at predetermined positions to crimp the terminal 90 by a process described later. Thereafter, when crimping is performed, the covering crimping piece 96 and the conductor crimping piece 97 are respectively crimped onto the covering portion 3a and the conductor portion 3b of the electric wire 3. In this embodiment, in this embodiment, as shown in FIG. 18, the first crimper side base portion 62 and the second crimper side base portion 63 are arranged side by side, and the first anvil side base portion 64 and the second anvil side are arranged. Base portions 65 are arranged side by side.

The first crimper side base portion 62, the second crimper side base portion 63, the first anvil side base portion 64, and the second anvil side base portion 65 are located above and below the crimping position T as shown in FIGS. Positioned and each is rotatably provided. More specifically, the first crimper side base portion 62 and the second crimper side base portion 63 are arranged on the upper side in the crimping position T, and the first crimper side base portion 63 is located on the front side of the second crimper side base portion 63. It is provided to be located. Further, the first anvil side base portion 64 and the second anvil side base portion 65 are arranged on the lower side in the crimping position T so that the first anvil side base portion 64 is located on the front side of the second anvil side base portion 65. Is provided.

The first crimper side base portion 62 is rotated by the power of the power unit 71 driven according to the instruction of the calculation unit 5, and the second crimper side base unit 63 is driven by the power of the power unit 72 driven according to the instruction of the calculation unit 5.

As a result, as shown in FIG. 20, a predetermined crimping die 51 corresponding to the covering crimping piece 96 and the conductor crimping piece 97 of the terminal 90 selected to be crimped is set so that the terminal 90 can be crimped. Thereafter, when the first crimper side base portion 62 and the second crimper side base portion 63 are pushed down by the power of the power portion 75 and the crimping is performed, the covering portion of the wire 3 positioned at the crimping position by the wire feeding portion 10. The covering crimping piece 96 and the conductor crimping piece 97 are respectively crimped to 3a and the conductor portion 3b.

By performing these processes, in the crimping step, the crimping mold 51 corresponding to the crimping shape of the terminal 90 of the product number selected to be crimped among the plurality of crimping molds 51 is positioned at the crimping position T. The terminal 90 and the end of the electric wire 3 are crimped. As a result, a terminal crimping electric wire in which the selected part number terminal 90 is crimped to the tip of the electric wire 3 is manufactured. According to the crimping part 50 (crimping process) according to the present embodiment, the crimping part 50 is independent of other parts, and therefore, when the crimping shapes of the terminals 90 match, the crimping die 51 is shared. be able to. For example, in the present embodiment, the case where the terminal 90 having the female connection portion 91 is used has been described. However, the multi-product number in which the one having the female connection portion 91 and the one having the male connection portion are mixed. There are cases where it is desired to selectively crimp a terminal to an electric wire. According to the crimping part 50 of this embodiment, even if the shapes of the connecting parts are different, these terminals can be crimped by the same crimping die 51 as long as the crimping shape is the same. For this reason, the number of parts can be reduced by sharing parts, and the manufacturing cost can be reduced by downsizing the equipment.

In the terminal crimped wire manufacturing apparatus 1 according to the second embodiment, the first crimper 66, the second crimper 67, the first anvil 68, and the second anvil 69 are formed separately.

Absent. In this case, the shape of the crimper portion is switched by switching the pair of the first crimper portion 66 and the second crimper portion 67 with respect to the shape of the crimping piece 95 of the terminal 90.

<Operation and Effect of Terminal Crimped Wire Manufacturing Device and Terminal Crimped Wire Manufacturing Method>
In order to explain the operation and effect of the terminal crimped electric wire manufacturing apparatus 1 and the terminal crimped electric wire manufacturing method according to the second embodiment, first, a conventional technique for crimping a terminal to an electric wire will be described. Conventionally, in the case of crimping a terminal to an electric wire, a crimping device including a part called an applicator has been used (see, for example, Japanese Patent Application Laid-Open No. 2007-35562).

FIG. 21 is a side view showing the crimping device disclosed in the above document as a conventional example. As shown in FIG. 21, the crimping apparatus 201 includes an applicator 202 prepared according to the product number of the terminal to be crimped, a drive unit 204 that moves the ram 203 of the applicator 202 up and down, and a terminal (not shown). ) Is provided with a terminal reel 211 that winds and accommodates a chain terminal 210 that is connected side by side with a belt-like carrier (not shown).

The applicator 202 includes a frame 205 that supports the ram 203 so as to be movable up and down, a crimper 206 fixed to the ram 203, an anvil 207 disposed opposite to the crimper 206, and a shank 208 provided at the upper end of the ram 203. And a terminal feed claw 209 that advances and retreats as the ram 203 moves up and down, and a terminal guide 212 that horizontally guides the chain terminal 210 from the terminal reel 211 to the anvil 207.

The drive means 204 includes a hydraulic cylinder (not shown) and the like, and can move the ram 203 up and down. By the lowering operation of the ram 203, the chain terminal 210 is moved one pitch at a time along the terminal guide 212 while the terminal feed claw 209 advances. As the ram 203 is lowered, the terminal at the front end in the feed direction is cut and separated from the carrier by cutting means (not shown) disposed in the vicinity of the anvil 207. Then, at the bottom dead center of the ram 203, an electric wire (not shown) is crimped to the terminal on the anvil 207 by the crimper 206. The electric wire is automatically or manually supplied onto the anvil 207 from the right side in FIG. As the ram 203 moves up, the terminal feed claw 209 moves backward and returns to the original position.

A crimping apparatus 201 having a conventional applicator 202 manufactures a terminal crimped electric wire in which a terminal is crimped to the tip of the electric wire by repeating the above-described processing and continuously crimping a terminal of the same product number to the electric wire. Met.

On the other hand, in recent years, there is a demand for a terminal crimped wire manufacturing apparatus that can handle a variety of terminals. However, in the above-described conventional crimping apparatus 201, the applicator 202 is a dedicated product that can handle only terminals having a unique product number. Therefore, in order to crimp terminals having different product numbers, the applicator corresponding to the product number is used. It is necessary to prepare 202 individually. For this reason, for example, when a plurality of applicators 202 are installed side by side in order to cope with multiple product numbers, there is a possibility that the equipment becomes large and the manufacturing cost increases. In addition, since the equipment is increased in size, the installation space may become excessive.

The terminal crimped wire manufacturing apparatus and the terminal crimped wire manufacturing method according to the second embodiment are made in view of the above-described circumstances, and the purpose thereof is a terminal crimped wire that can realize downsizing of equipment and reduction of manufacturing cost. It is providing the manufacturing apparatus and the manufacturing method of a terminal crimping electric wire.

As described above, the terminal crimping electric wire manufacturing apparatus 1 according to the second embodiment sends a chain terminal by an applicator configured corresponding to the terminal product number as in the conventional crimping apparatus, and the terminal is connected from the chain terminal. It is not what cuts and crimps | bonds, but each function of these feed functions, cutting functions, and crimping | compression-bonding functions is comprised separately. That is, in the terminal crimping electric wire manufacturing apparatus 1 according to the second embodiment, the terminal reel in the conventional crimping apparatus is abolished, and the terminals 90 prepared in advance are transferred and supplied. Specifically, a terminal 90 having a product number selected from a plurality of product numbers is placed on the placement surface 81 by the take-out unit 20, and the terminal 90 is transferred to the delivery position R2 by the terminal transfer unit 30, and thereafter , And supplied to the crimping section 50. In the crimping portion 50, the terminal 90 and the electric wire 3 are crimped by the crimping die 51 corresponding to the selected crimping shape of the terminal 90. Thus, according to the terminal crimped wire manufacturing apparatus 1 according to the second embodiment, switching to a different product number can be handled only by switching the product number of the terminal 90 taken out by the takeout unit 20 and switching the crimping die 51. Switching time can be shortened. In addition, by sharing parts, it is possible to reduce the number of dedicated parts, so the equipment can be downsized and manufacturing costs can be reduced. Further, the number of dedicated parts due to the terminal product number is reduced, and the product number can be easily switched, so that it is possible to flexibly cope with an increase or decrease in the number of product numbers.

In addition, in the crimping device using the conventional applicator, even if the terminal group has the same crimping shape of the terminal, it is necessary to use a different applicator if the shape of the connecting portion is different and the product number is different. The number of applicators has increased. On the other hand, according to the terminal crimping electric wire manufacturing apparatus 1 according to the second embodiment, the crimping process is independent of other processes. Can be shared. For this reason, the number of dedicated parts can be reduced by sharing the parts, and the equipment can be downsized to reduce the manufacturing cost.

In addition, in the conventional crimping device, since the chain terminals need to be always connected to the applicators, it is necessary to arrange the terminal reels so as to face the rows of the applicators, which increases the installation space. It was. On the other hand, according to the terminal crimping electric wire manufacturing apparatus 1 according to the second embodiment, the takeout part 20 and the terminal transfer part 30 for supplying the terminal 90 and the crimping part 50 are not coupled, and the terminal Since the reels are abolished and the terminal 90 of the product number selected to be crimped is transferred and supplied by the take-out unit 20 and the terminal transfer unit 30, the installation space of the entire apparatus can be reduced and the flexibility of layout can be improved.

Moreover, according to the terminal crimping electric wire manufacturing apparatus 1 which concerns on 2nd Embodiment, in the terminal transfer part 30, it correct | amends the attitude | position of the terminal 90 fixed to the fixing | fixed part 35 based on the identification result of a mounting state, and transfers Therefore, the terminal 90 can be reliably positioned at the delivery position R2.

Moreover, according to the terminal crimping electric wire manufacturing apparatus 1 according to the second embodiment, since the support base 21 rotates, the storage box 22 that stores the terminal 90 of the selected product number is positioned at the take-out position S. Compared with the case where the moving unit 23 moves to the arrangement position of the selected storage box 22 from among the plurality of fixed storage boxes 22 arranged and takes out the terminal 90, the moving distance of the moving unit 23 is short, If the moving speed is the same, the moving time is short. For this reason, the processing speed of a manufacturing apparatus can be improved. In addition, since the moving distance after fixing becomes short, errors that tend to occur during movement can be reduced, and the position accuracy can be improved.

(Third embodiment)
Hereinafter, although the terminal crimping electric wire manufacturing apparatus which concerns on 3rd and 4th embodiment is demonstrated, about the structure similar to the terminal crimping electric wire manufacturing apparatus which concerns on 1st and 2nd embodiment, the same code | symbol is used and detailed description is given. Omitted. FIG. 22 is a perspective view showing a wire harness component transfer device according to the third embodiment, and FIG. 23 is a side view of FIG. The block diagram which shows the connection state of each part of the wire harness components transfer apparatus which concerns on 3rd Embodiment is the same as FIG.

<Crimping part, crimping process>
About the crimping | compression-bonding part 50 and a crimping | compression-bonding process, since it is the same as 2nd Embodiment, detailed description is abbreviate | omitted.

As described above, the terminal crimping electric wire manufacturing apparatus 1 according to the fourth embodiment sends the chain terminal by the applicator configured corresponding to the terminal product number as in the conventional crimping apparatus described in the second embodiment. The terminal is not cut and crimped from the chain terminal, but the feed function, the cutting function, and the crimping function are separated from each other. That is, in the terminal crimping electric wire manufacturing apparatus 1 according to the fourth embodiment, the terminal reel in the conventional crimping apparatus is abolished, and the terminal 90 prepared in advance in a separate state is transferred and supplied. Specifically, the terminal 90 housed in the housing box 22 that houses the terminal 90 of the selected product number among the plurality of housing boxes 22 each housing the terminal 90 having a different product number is fixed by the fixing portion 35. Then, it is transferred to the delivery position R2 and supplied to the crimping part 50. In the crimping portion 50, the terminal 90 and the electric wire 3 are crimped by the crimping die 51 corresponding to the selected crimping shape of the terminal 90. As described above, according to the terminal crimped wire manufacturing apparatus 1 according to the present embodiment, switching to a different product number can be handled only by switching the terminal product number fixed by the fixing portion 35 and switching the crimping die 51. Can be shortened. In addition, by sharing parts, it is possible to reduce the number of dedicated parts, so the equipment can be downsized and manufacturing costs can be reduced. Further, the number of dedicated parts due to the terminal product number is reduced, and the product number can be easily switched, so that it is possible to flexibly cope with an increase or decrease in the number of product numbers.

In addition, in the crimping device using the conventional applicator, even if the terminal group has the same crimping shape of the terminal, it is necessary to use a different applicator if the shape of the connecting portion is different and the product number is different. The number of applicators has increased. On the other hand, according to the terminal crimping electric wire manufacturing apparatus 1 according to the fourth embodiment, the crimping process is independent of the other processes. Can be shared. For this reason, the number of dedicated parts can be reduced by sharing the parts, and the equipment can be downsized to reduce the manufacturing cost.

Also, in a conventional crimping device using an applicator, it is necessary to always connect the chain terminal to the applicator, so it is necessary to arrange the terminal reels facing the row of applicators, and the installation space is large. There was a problem of becoming. On the other hand, according to the terminal crimping electric wire manufacturing apparatus 1 according to the present embodiment, the terminal transfer unit 30 for supplying the terminal 90 and the crimping unit 50 are not coupled, and the terminal reel is abolished. Since the terminal 90 of the product number selected to be crimped is transferred and supplied by the terminal transfer unit 30, the installation space of the entire apparatus can be reduced and the layout flexibility can be improved.

Further, according to the terminal crimped wire manufacturing apparatus 1 according to the present embodiment, since the support base 21 rotates, the storage box 22 that stores the terminal 90 of the selected product number is positioned at the fixed position S. Compared with the case where the fixed portion 35 moves to the arrangement position of the storage box 22 selected from the plurality of storage boxes 22 that are arranged and the terminal 90 is taken out, the movement distance of the fixed portion 35 is short and moves. If the speed is the same, the travel time is short. For this reason, the processing speed of a manufacturing apparatus can be improved. Moreover, since the moving distance after fixing becomes short, the error which tends to occur at the time of movement can be reduced, and the quality of the product can also be improved.

That is, the transfer unit of the present invention can be realized as long as the storage box 22 and the fixed part 35 are relatively moved by the movement of at least one of the support base 21 and the fixed part 35. If the support 21 is configured to move as in the above embodiment, the processing speed and position accuracy of the manufacturing apparatus can be improved as described above. On the other hand, if the support base 21 is configured to be fixed, a rotation mechanism (support base drive unit) or the like for rotating the support base 21 becomes unnecessary, so that the installation space of the entire apparatus is reduced and the layout is made. Can be improved. Moreover, cost reduction can be achieved.

Moreover, in the said 4th Embodiment, it was set as the structure which uses the storage box 22 which accommodates the terminal 90 from which a product number differs as an accommodating part, However, The terminal 90 of each product number is accommodated as one collection so that it may not mix mutually. Any other configuration may be used as long as the fixing portion 35 can fix the terminal 90.

Moreover, in the said 4th Embodiment, the terminal 90 for pinpointing from the some terminal 90 accommodated in the storage box 22 which accommodates the terminal 90 of the selected product number which the imaging | photography part 33 acquires is specified. Although the configuration using the three-dimensional position and orientation of the accommodated terminal 90 as information has been described, other information may be used. In the above-described embodiment, the configuration in which the imaging unit 33 is a distance sensor using a laser has been described. However, other three-dimensional recognition methods may be used, for example, a method based on image recognition, infrared rays, X-rays, etc. A technique based on TOF (Time of Flight) may be used.
