FIG. 19 is a side view showing the crimping device disclosed in Patent Document 1 as a conventional example. As shown in FIG. 19, the crimping apparatus 101 includes an applicator 102 prepared according to the product number of the terminal to be crimped, drive means 104 that moves the ram 103 of the applicator 102 up and down, and a terminal of the same product number (not shown). And a terminal reel 111 that winds and accommodates a chain terminal 110 that is connected side by side with a belt-like carrier (not shown).

The applicator 102 includes a frame 105 that supports the ram 103 so as to be movable up and down, a crimper 106 fixed to the ram 103, an anvil 107 disposed opposite the crimper 106, and a shank 108 provided at the upper end of the ram 103. And a terminal feed claw 109 that advances and retreats as the ram 103 moves up and down, and a terminal guide 112 that guides the chain terminal 110 horizontally from the terminal reel 111 (reel part) to the anvil 107.

The driving means 104 includes a hydraulic cylinder (not shown) and the like, and can move the ram 103 up and down. By the lowering operation of the ram 103, the chain terminal 110 is moved one pitch at a time along the terminal guide 112 while the terminal feed claw 109 moves forward. As the ram 103 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 107. Then, at the bottom dead center of the ram 103, an electric wire (not shown) is crimped and connected to the terminal on the anvil 107 by the crimper 106. The electric wire is automatically or manually supplied onto the anvil 107 from the right side in FIG. By the raising operation of the ram 103, the terminal feed claw 109 moves backward and returns to the original position.

thing.

According to the terminal crimped wire manufacturing apparatus of (1) above, in the terminal supply unit, the terminal of the selected product number is cut by the terminal supply unit selected from among the plurality of terminal supply units having different product numbers of the terminals. In the crimping portion, the terminal and the electric wire are crimped by a crimping die corresponding to the crimping shape of the terminal. In this way, switching to a different product number can be handled only by switching the terminal supply unit and switching the crimping type, so that the 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.

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 of (1) above, since the crimping part is independent of other parts, the crimping die is shared when the crimping shapes of the terminals match. be able to. 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 apparatus, since the chain terminal needs to be always connected to the applicator, it is necessary to arrange the terminal reel so as to face the row of the applicators. There was a problem of being small. On the other hand, according to the terminal crimping electric wire manufacturing apparatus of (1) above, the terminal supply unit and the crimping unit are not coupled, and the terminal supply unit cuts and supplies the terminal. The degree of freedom can be improved. Since the reel portions are arranged in an annular shape, the space of the equipment is reduced as compared with the case where the reel portions are arranged facing the row of applicators as in the conventional crimping apparatus. be able to.

According to the terminal crimped wire manufacturing apparatus of (2) above, when the terminal is moved from the cutting position to the crimping position, the position and posture of the terminal are corrected according to the amount of deviation detected based on the information acquired by the detection unit. Therefore, the terminal is reliably positioned at the crimping position. For this reason, it is possible to improve the quality by improving the accuracy of terminal crimping, reduce the occurrence of defects, and shorten the working time. In addition, in the conventional crimping apparatus, there is no other way but to inspect whether the crimping is correctly performed after the crimping, whereas according to the terminal crimping electric wire manufacturing apparatus of the above (2), the terminal position is corrected and positioned. Since the terminal is then crimped, the terminal position before the crimping can be guaranteed, and quality control is easy to implement.

According to the terminal crimped wire manufacturing apparatus of (3) above, since the information for detecting the amount of deviation is acquired by the detection unit after the terminal is cut in a state of being fixed to the moving part, the amount of deviation was detected. The terminal will not be fixed again later. For this reason, a terminal can be reliably located in a crimping position. Further, since the terminal is cut in a state where the base is placed on the pedestal on the plane and is fixed to the moving part, the terminal is displaced in a direction perpendicular to the pedestal plane (plane along the base). Can be reduced. Since there is no need to consider the deviation in the direction perpendicular to the pedestal plane, the detection unit may acquire information for detecting the deviation amount from the reference state in the plane along the base. That is, in this case, only the deviation on the two-dimensional plane needs to be considered. Accordingly, the configuration of the detection unit can be simplified, and the movement amount in the correction of the position and orientation can be reduced, so that the movement can be highly accurate and the processing speed can be increased.

According to the terminal crimped wire manufacturing apparatus of the above (4), the moving part corresponding to the outer shape of the terminal of the selected product number is obtained by the rotation of the rotation holding part that holds the plurality of moving parts so as to be arranged on the circumference. After fixing the terminal at the cutting position, the terminal is sequentially positioned at the detection position and the crimping position, and the terminal is moved to the crimping position. For this reason, since the said terminal can be moved using the moving part corresponding to the outer shape of the selected terminal, for example, the moving accuracy is improved as compared with the case where the same moving part is used for any terminal. it can. In addition, for example, a moving mechanism can be realized with a simple structure and an installation space can be reduced as compared with a case where a plurality of moving units are linearly arranged in a line.

According to the terminal crimped electric wire manufacturing apparatus of (5) above, the moving part fixes the terminal by adsorbing the end surface of the terminal connecting part opposite to the crimping piece side (base part side) by air pressure. For example, the moving mechanism can be realized with a simple structure as compared with the case of being sandwiched by an arm or the case of electromagnetic adsorption.

According to the terminal crimped electric wire manufacturing apparatus of (6) above, since the amount of terminal displacement can be grasped based on an image photographed by, for example, a camera, a sensing part can be realized with a simple structure.

According to the terminal crimped wire manufacturing apparatus of (7) above, the mold holding part positions the crimping die corresponding to the shape of the crimping piece of the selected part number terminal at the crimping position, so that the terminal of the multi-part number is supplied to the terminal. Even if it is a case where it supplies from a part, a terminal can be crimped | bonded favorably. In addition, as described above, in the conventional crimping device, even if the shape of the crimping piece is the same, if the shape of the connection portion is different and the product number is different, it is necessary to use a different applicator. On the other hand, according to the terminal crimped electric wire manufacturing apparatus of the above (7), when the shapes of the crimping pieces match, the crimping die 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.

According to the terminal crimped wire manufacturing apparatus of (8) above, a plurality of crimpers and anvils are arranged so as to protrude outward from the rotating member, respectively, and correspond to the shape of the crimping piece of the terminal of the selected product number. Since the crimper portion and the anvil portion are positioned at the crimping position, the installation space can be further reduced. As a result, it is possible to realize a terminal crimped electric wire manufacturing apparatus that can handle multi-part number terminals.

According to the terminal crimped wire manufacturing apparatus of (9) above, each of the covering crimping piece for crimping the covering portion and the conductor crimping piece for crimping the conductor portion protrudes outward from the rotating member in the same manner as described above. The specific first and second crimper parts and the first and second anvil parts are respectively in the crimping positions according to the shape of the covering crimping piece and the conductor crimping piece of the terminal of the selected product number. Since it can be positioned, the installation space can be further reduced.
In addition, the 1st calculating part mentioned above, the 2nd calculating part, and the 3rd calculating part may be comprised by one arithmetic device, and may be comprised by two or more arithmetic devices.

thing.

According to the method of manufacturing a terminal crimped electric wire of (10) above, in the terminal supply step, the terminal of the selected product number is cut by the terminal supply unit selected from among the plurality of terminal supply units having different terminal product numbers. In the crimping step, the terminal and the electric wire are crimped by a crimping die corresponding to the crimping shape of the terminal. In this way, switching to a different product number can be handled only by switching the terminal supply unit and switching the crimping type, so that the 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.

In addition, in the manufacturing method using the conventional applicator, even in the terminal group in which the crimping shape of the terminal is the same, if the shape of the connecting portion is different and the product number is different, it is necessary to use a different applicator. The number of applicators has increased. On the other hand, according to the method for manufacturing a terminal crimped electric wire of (10) above, since the crimping process is independent of other processes, if the crimping shapes of the terminals match, the crimping mold is shared. can do. 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.

Further, in the conventional manufacturing method, it is necessary to always connect the chain terminal to the applicator. Therefore, it is necessary to arrange the terminal reel so as to face the row of the applicators. There was a problem of being small. On the other hand, according to the method of manufacturing a terminal crimped electric wire of (10) above, the terminal supply process and the crimping process are not combined as one process, and the terminal is cut in the terminal supply process and selected as a subsequent process. Since the terminals are supplied, the degree of freedom of terminal reel layout can be improved. For example, the terminal reel can be arranged in an annular shape on the reel base, and the reel base can be rotated so that the terminal of the selected product number is positioned at the cutting position, thereby saving the space of the equipment. Can do.

According to the method for manufacturing a terminal crimped electric wire of (11) above, when the terminal is moved from the cutting position to the crimping position in the moving process, the position of the terminal is determined according to the amount of deviation detected based on the information acquired in the detecting process. Since the posture is corrected, the terminal is reliably positioned at the crimping position. For this reason, it is possible to improve the quality by improving the accuracy of terminal crimping, reduce the occurrence of defects, and shorten the working time. Further, in the conventional manufacturing method, it has only been inspected whether or not the crimping is correctly performed after the crimping. On the other hand, according to the manufacturing method of the terminal crimping electric wire of the above (11), the terminal position is corrected and positioned. Then, since the terminal is crimped, the terminal position before the crimping can be guaranteed, and quality control is easy to implement.

According to the manufacturing method of the terminal crimped electric wire of the above (12), since the information for detecting the deviation amount is acquired in the detection step after being cut in a state where the terminal is fixed in the terminal supply step, the deviation amount is detected. The terminal will not be fixed again later. For this reason, a terminal can be reliably located in a crimping position. In addition, since the terminal is cut in a state where the base is placed on the pedestal on the plane and is fixed, it is possible to reduce misalignment of the terminal in a direction perpendicular to the pedestal plane (a plane along the base). . Since it is not necessary to consider the deviation in the direction perpendicular to the pedestal plane, in the detection step, information for detecting the deviation amount from the reference state in the plane along the base portion may be acquired. That is, in this case, only the deviation on the two-dimensional plane needs to be considered. Accordingly, the configuration for detecting the deviation amount can be simplified, and the movement amount in the correction of the position and orientation can be reduced, so that the movement can be highly accurate and the processing speed can be increased.

According to the manufacturing method of the terminal crimped electric wire of (13) above, the moving part corresponding to the outer shape of the terminal of the selected product number is rotated at the cutting position by the rotation of the plurality of moving parts arranged on the circumference. After fixing the terminal, the terminal is sequentially positioned at the detection position and the crimping position, and the terminal is moved to the crimping position. For this reason, since the said terminal can be moved using the moving part corresponding to the outer shape of the selected terminal, for example, the moving accuracy is improved as compared with the case where the same moving part is used for any terminal. it can. In addition, for example, a moving mechanism can be realized with a simple structure and an installation space can be reduced as compared with a case where a plurality of moving units are linearly arranged in a line.

According to the method of manufacturing a terminal crimped electric wire of (14) above, in the moving step, the terminal is fixed by adsorbing the end surface of the terminal connection portion opposite to the crimping piece side (base portion side) by air pressure. For example, the moving mechanism can be realized with a simple structure as compared with a case where the arm is held by an arm or a case where it is electromagnetically attracted.

According to the method of manufacturing a terminal crimped electric wire of (15) above, since the amount of terminal displacement can be grasped based on, for example, an image photographed by a photographing unit that is a camera, a configuration for detecting the amount of displacement with a simple structure.

Even if it is a case where it supplies in a process, a terminal can be crimped | bonded favorably. In addition, as described above, in the conventional manufacturing method, even if the shape of the crimping piece is the same, if the shape of the connecting portion is different and the product number is different, it is necessary to use a different applicator. On the other hand, according to the manufacturing method of the terminal crimping electric wire of the above (16), when the shapes of the crimping pieces match, the crimping die 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.

According to the method for manufacturing a terminal crimped electric wire of (17) above, a plurality of crimpers and anvils are arranged so as to protrude outward from the rotating member, and correspond to the shape of the crimping piece of the terminal of the selected product number. Since the crimper portion and the anvil portion are positioned at the crimping position, the installation space can be further reduced. As a result, the manufacturing method of the terminal crimping electric wire which can respond to a multi-part number terminal is realizable.

According to the method for producing a terminal crimped electric wire of (18) above, the covering crimping piece for crimping the covering portion and the conductor crimping piece for crimping the conductor portion are projected outward from the rotating member in the same manner as described above. The specific first and second crimper portions and the first and second anvil portions are respectively crimped positions according to the shape of the covering crimping piece and the conductor crimping piece of the terminal of the selected product number. Therefore, the installation space can be further reduced.

As shown in FIG. 2, the electric wire feeder 10 sends the electric wire 81 to be crimped to the terminal 93 from the point A to the point B in the arrow X direction. The electric wire 81 is a covered electric wire in which a conductor portion which is a conductive core wire is covered with an insulating covering portion, and is peeled off in a process before point A so that the conductor portion is exposed at the end portion. ing. One end side and the other end side of the electric wire 81 are clamped by two adjacent moving mechanisms 13 out of a plurality of moving mechanisms 13 that sandwich the electric wire 81 and send it in the direction of arrow X at a predetermined pitch. Moving. And in the predetermined crimping | compression-bonding position (position shown with the code | symbol T in FIG. 2) by the two crimping | compression-bonding parts 60 arrange | positioned in the vicinity of the movement path | route of the electric wire 81 in the part which the conductor part in each of these both ends exposed. The terminal 93 is crimped. The electric wire 81 to which the terminal 93 has been crimped is then sent before the point B and processed in the subsequent process. For example, the electric wire 81 can be configured to be inserted into the housing by an insertion device (not shown). Further, as described above, the wire 81 is stripped of the coating on the distal end side in the previous process before being sent to the point A. That is, the terminal crimped electric wire manufacturing apparatus 1 according to the present embodiment constitutes a part of the manufacturing apparatus, and the electric wire extends from point A as the work start position to point B as the work end position in the terminal crimped electric wire manufacturing apparatus 1.

That is, the terminal supply unit 20, the terminal transfer unit 40, and the crimping unit 60 function as a terminal feeding device that feeds the selected terminal 93 to the crimping position T.

FIG. 4: is a block diagram which shows the connection state of each part of the terminal crimping electric wire manufacturing apparatus which concerns on an Example. As illustrated in FIG. 4, the electric wire feeding unit 10, the terminal supply unit 20, the terminal transfer unit 40, and the crimping unit 60 are each connected to the calculation unit 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, and includes an electric wire feeding unit 10, a terminal supply unit 20, a terminal transfer unit 40, and The operation of each crimping part 60 is controlled. Below, among these, the structure of the terminal supply part 20, the terminal transfer part 40, and the crimping | compression-bonding part 60 which are terminal delivery apparatuses is demonstrated in order.
In addition, as shown in FIG. 2, the terminal crimping electric wire manufacturing apparatus 1 according to the present embodiment includes two terminal transfer units 40 and two crimping units 60. However, since these are the same, in the following, Only one of them will be described for the sake of simplicity.

<Terminal supply unit, terminal supply process>
The terminal supply part 20 is arrange | positioned in the rear side in the terminal crimping electric wire manufacturing apparatus 1, as shown in FIG. As shown in FIGS. 3 and 5, the terminal supply unit 20 includes a plurality of terminal supply units 21, a circular reel base 23 that rotatably holds the plurality of terminal supply units 21, and a reel base 23 that is driven by the driving force. And a reel base driving device 24 for rotationally driving the motor as main components. The terminal supply unit 21 has a plurality of reel portions 22 for winding and housing a chain terminal 91 in which terminals 93 of the same product number are connected side by side with a belt-like carrier 95. The plurality of reel portions 22 are held on a reel base 23 so as to be arranged in an annular shape. A chain terminal 91 of a terminal 93 having a different product number is wound around each of the reel portions 22.

Further, as shown in FIG. 5, the terminal supply unit 21 includes a terminal feed portion 25 provided in each reel portion 22, and a chain terminal 91 provided on the distal end side in the terminal feed direction of the terminal feed portion 25. And a cutting blade 27 (see FIGS. 6 to 8) used for cutting the terminal 93. The terminal feeding unit 25 can feed the chain terminal 91 wound around the reel unit 22 to a predetermined position toward the front side.

The cutting blade 27 is a member used for cutting the terminal 93 from the chain terminal 91 and is configured as a part of the cutting portion 26. As shown in FIGS. 6 to 8, the cutting part 26 includes a cutting blade 27 and a pressing part 28. The cutting blade 27 is disposed at a cutting position S (a position indicated by a symbol S in FIG. 5; a position where the distal end side terminal 93 is positioned in FIGS. 6 to 8). The terminal 93 positioned at the tip of the chain terminal 91 sent by the feeding unit 25 is positioned above the terminal 93 so as to be disconnected from the carrier 95. At the cutting position S, as shown in FIG. 8, the terminal 93 is placed on the pedestal 29 so that the base 97 is positioned on the planar pedestal 29. The pressing portion 28 is configured to be movable in the vertical direction by a power unit (not shown), and is disposed above the cutting blade 27. When the terminal is cut, the pressing portion 28 moves downward from the position shown in FIGS. 6 and 8, contacts the cutting blade 27, and pushes down the cutting blade 27. Thereby, the cutting blade 27 cuts and separates the terminal 93 from the carrier 95.
At this time, as shown in FIGS. 6 to 8, a moving portion 43 of the terminal transfer portion 40 described later adsorbs and fixes the terminal 93. The moving unit 43 moves while fixing the cut terminal 93.

The terminal supply unit 20 having the above configuration has a function of cutting and supplying the selected part number terminal 93 at a predetermined cutting position S. More specifically, the arithmetic unit 5 first controls the reel base driving device 24 and accommodates the chain terminal 91 of the terminals 93 selected to perform crimping among the plurality of terminal supply units 21. The reel base 23 is rotated so that the terminal supply unit 21 is positioned at a position corresponding to the cutting position S (in front of the cutting position S). And the calculating part 5 controls the terminal sending part 25, sends the chain terminal 91 of the selected terminal supply unit 21 forward, and positions the terminal 93 located at the tip of the chain terminal 91 at the cutting position S. Thereafter, the calculation unit 5 controls the power unit described above, and depresses the pressing unit 28 and presses the cutting blade 27 against the terminal 93 to cut the terminal 93 from the carrier 95.

By executing these processes, the terminal supply unit 21 selected from among the plurality of terminal supply units 21 positions the terminal 93 of the selected product number at the cutting position S in the terminal supply process by the terminal supply unit 20. It is done. The terminal 93 positioned at the cutting position S is separated from the chain terminal 91 by the cutting unit 26 and supplied to the terminal transfer unit 40. When cutting and supplying the terminal 93 having a different product number, the different terminal supply unit 21 corresponding to the terminal 93 having the different product number is positioned at a position corresponding to the cutting position S. Thereby, the terminals 93 with different product numbers are fixed and moved by the moving unit 43, so that the terminals 93 with different product numbers can be supplied to the terminal transfer unit 40. Even when the terminals 93 having different product numbers are supplied from different terminal supply units 21, the cutting positions S are the same. Further, the position (supply position) where the moving unit 43 receives the terminal 93 in a fixed manner is the same. Thus, according to the terminal supply unit 20, switching to a different product number can be handled only by switching the terminal supply unit 21 by rotation of the reel base 23, so that the switching time can be shortened. Further, since the reel portions 22 are arranged in an annular shape, the space of the equipment can be saved as compared with the case where the reel portions are arranged facing the row of applicators as in the conventional crimping apparatus. Can be planned.

<Terminal transfer section, terminal transfer process>
The terminal transfer part 40 is arrange | positioned between the terminal supply part 20 and the crimping | compression-bonding part 60 in the terminal crimping electric wire manufacturing apparatus 1, as shown in FIG. As shown in FIGS. 9 to 11, the terminal transfer unit 40 is held by a circular rotation holding unit 41 configured to be rotatable, and arranged on the outer periphery of the rotation holding unit 41 by the rotation holding unit 41. A plurality of moving units 43 and a detecting unit 45 including a photographing unit 46 and an illuminating unit 47 are provided as main components. In addition, the terminal transfer process by the terminal transfer unit 40 includes a moving process in which the terminal 93 of the selected product number is fixed and moved at the cutting position S, and a deviation of the terminal 93 from a predetermined reference state. And a detection step of acquiring information for detecting the quantity.

As shown in FIG. 9, the rotation holding unit 41 is fixed to the support column 42 and connected to the belt 48. The belt 48 is rotated by the driving force of the belt driving device 49. Therefore, the rotation holding unit 41 is driven by the belt driving device 49 and rotates around the support column 42.

The moving unit 43 is configured to be movable, and moves the terminal 93 cut at the cutting position S by suction and fixing at the cutting position S (supply position) (moving step). In this embodiment, the moving part 43 fixes the terminal 93 to the suction part 43a by adsorbing the connecting part 96 of the terminal 93 by air pressure, as shown in FIGS. That is, as shown in FIG. 8, the moving portion 43 has a ventilation groove 43 c through which air passes and is formed in communication with the suction portion 43 a, and adsorbs and fixes the upper surface of the connection portion 96 by negative pressure suction. A plurality of moving portions 43 are prepared corresponding to the outer shapes of the plurality of terminals 93 that can be supplied by the terminal supply portion 20 (in the present embodiment, corresponding to the outer shape of the connecting portion 96 to be attracted). . For example, when the shape of the terminal 93 and the moving unit 43 correspond one-to-one, the same number of moving units 43 as the terminals 93 that can be supplied by the terminal supply unit 20 are prepared. Thereby, since the terminal 93 can be moved using the moving part 43 corresponding to the outer shape of the selected terminal 93, for example, compared with the case where the same moving part 43 is used for any terminal 93. , Moving accuracy can be improved. Further, when there is a terminal 93 that can be supplied by the terminal supply unit 20 with the same or similar outer shape (for example, when the shape of the crimping piece 98 is different but the shape of the connection part 96 is the same) Or when the shape of the terminal 93 and the moving part 43 do not correspond one-to-one, such as when the required accuracy in suction and fixing is relatively low, the number of moving parts 43 may be reduced more than that. Absent.

9 and 10, the plurality of moving parts 43 are held radially on the circumference of the rotation holding part 41 so that the suction parts 43 a protrude in the outer circumferential direction of the rotation holding part 41. . The moving part 43 has an arm 43b extending in the vertical direction. As shown in FIG. 9, the arm 43 b is configured to be movable in the vertical direction by the driving force of the arm driving device 44. Further, the arm 43b is configured to be movable in the front-rear and left-right directions as the rotation holding portion 41 is moved relative to the support column 42 in the front-rear and left-right directions by the power of a power unit (not shown). Further, the arm 43 b is configured to be rotatable on a plane perpendicular to the vertical direction by the driving force of the arm driving device 44. Accordingly, the moving unit 43 is configured to be movable in the up-down direction, the left-right direction, and the front-rear direction, and is configured to be rotatable on a plane perpendicular to the up-down direction.

Therefore, in the moving process by the moving unit 43, the moving unit 43 corresponding to the shape of the terminal 93 supplied by the terminal supply unit 20 among the plurality of moving units 43 held by the rotation holding unit 41 is positioned at the cutting position S. Thus, regardless of the shape of the selected terminal 93, the moving unit 43 can move with the terminal 93 fixed well. The movement path of the terminal 93 will be described later.

The detection unit 45 acquires information for detecting the amount of deviation from a predetermined reference state in a fixed state with respect to the moving unit 43 of the terminal 93 (detection step). As shown in FIG. 9, the detection unit 45 is installed on the upper side in the vicinity of the rotation holding unit 41 and at a position corresponding to the imaging unit 46 (in this embodiment, directly below). And an illumination unit 47. The imaging unit 46 is a camera, for example, and acquires an image by imaging the subject illuminated by the illumination unit 47. The illumination unit 47 is a backlight, for example. That is, in this embodiment, as shown in FIG. 9, the detection position indicated by the symbol R is arranged on the illumination unit 47, and the photographing unit 46 is in the state where the terminal 93 is positioned at the detection position R. Get the image. And based on the acquired image, the calculating part 5 calculates and grasps | ascertains the deviation | shift amount from the reference | standard state of the fixed state of the terminal 93. FIG. Thereby, the deviation | shift amount from the predetermined reference | standard state of the fixed state with respect to the moving part 43 of the terminal 93 is detected. That is, in the terminal crimped electric wire manufacturing apparatus 1 according to the present embodiment, even when the suction fixing of the terminal 93 by the moving unit 43 is deviated from a predetermined reference state, the amount of deviation is detected in the detection process. Can do. By using this amount of deviation, when the terminal 93 is moved from the cutting position S to the crimping position T in the movement process, the position and orientation of the terminal 93 according to the amount of deviation detected based on the information acquired by the detection unit 45. Thus, the terminal 93 can be reliably positioned at the crimping position T.

In this embodiment, the calculation unit 5 is a position on a plane along the base 97 of the terminal 93 based on an image acquired from the imaging unit 46 and taken from the direction orthogonal to the base 97 (from above). And grasp the amount of deviation from the reference state of posture. That is, in the present embodiment, the detection process includes an imaging process for imaging the terminal 93. In the terminal crimped electric wire manufacturing apparatus 1 according to this embodiment, as described above, the terminal 93 is placed on the pedestal 29 on the plane, and the moving unit 43 fixes the terminal 93 while the terminal 93 is fixed. 93 is cut from the carrier 95. Thereby, the shift | offset | difference of the fixed position of the terminal 93 in the direction (up-down direction) perpendicular | vertical to a base plane (namely, plane which follows the base part 97 of the terminal 93) is reduced. For this reason, since there is no need to consider the deviation in the vertical direction, the detection unit 45 (detection step) acquires information for detecting the deviation amount from the reference state on the plane along the base part 97.

More specifically, based on the image acquired from the imaging unit 46, the calculation unit 5 is based on the two directions and the rotation angle reference in the plane along the base 97 in the fixed state of the terminal 93 with respect to the moving unit 43. The amount of deviation is calculated. In the present embodiment, the amount of deviation from the reference is calculated for the first direction coinciding with the longitudinal direction of the terminal 93, the second direction orthogonal to the first direction, and the rotation angle. For example, for the second direction, based on the acquired image, the positions of both side walls of the connection portion 96 that are the end portions in the second direction of the terminal 93 are grasped, and the positions of the grasped both side walls, A reference position where both side walls should be positioned is compared, and a positional deviation amount in the second direction is calculated. The same applies to the position and rotation angle (posture) in the first direction. The computing unit 5 moves the moving unit 43 so that the terminal 93 is positioned at the crimping position T by correcting the position and orientation of the terminal 93 based on the grasped deviation amount. That is, the calculation unit 5 moves the moving unit 43 by an amount corresponding to the amount of displacement until the terminal 93 moves from the cutting position S to the crimping position T, so that the terminal 93 is reliably positioned at the crimping position T. .
If the terminal 93 is not photographed within a predetermined range in the image photographed by the photographing unit 46, the arithmetic unit 5 determines that the suction fixing of the terminal 93 by the moving unit 43 has failed, and the device Can be stopped. For this reason, in the terminal crimping electric wire manufacturing apparatus 1 according to the present embodiment, the terminal 93 can be crimped with high accuracy by correcting the position and orientation, and quality control can be facilitated.

Subsequently, the movement path of the terminal 93 will be described with reference to FIG. FIG. 11 is a schematic diagram for explaining a terminal movement path, and is a plan view of a terminal transfer section. As shown in FIG. 11, in the moving process, the chain terminal 91 of the terminal 93 selected to be crimped is sent from the terminal feeding portion 25 to the cutting position S from the rear to the front. The terminal 93 separated from the chain terminal 91 by the cutting unit 26 at the cutting position S is sucked and fixed at the cutting position S by the moving unit 43 corresponding to the selected shape of the terminal 93. The terminal 93 fixed to the moving unit 43 is moved to the detection position R on the illumination unit 47 as indicated by an arrow in FIG. After the image is taken by the photographing unit 46 at the position, the terminal 93 is moved to the crimping position T.

As described above, the detection position R at which the detection unit 45 acquires information for detecting the cutting position S and the amount of deviation on the rotation trajectory of the terminal 93 fixed to the moving unit 43 when the rotation holding unit 41 rotates. , And the crimping position T are arranged in this order. And the calculating part 5 is the detection position after the moving part 43 corresponding to the outer shape of the terminal 93 of the selected product number among the plurality of moving parts 43 is positioned at the cutting position S and the terminal 93 is fixed. The rotation holding portion 41 is rotated so as to be sequentially positioned at R and the crimping position T.

According to the terminal transfer unit 40 (moving step) having the above configuration, the terminal 93 can be moved to the crimping position T using the moving unit 43 corresponding to the outer shape of the selected terminal 93. Compared to the case where the same moving unit 43 is used for the terminal 93, the moving accuracy can be improved. Further, since the moving part 43 is held by the circular rotation holding part 41, for example, the moving mechanism has a simple structure as compared with the case where a plurality of moving parts 43 are linearly arranged in a line. This can be realized and the installation space can be reduced. Further, when the terminal 93 is moved from the cutting position S to the crimping position T, the position and orientation of the terminal 93 are corrected according to the amount of deviation detected based on the information (image) acquired by the detection unit 45 in the detection process. Therefore, the terminal 93 can be reliably positioned at the crimping position T in the moving process. Further, since the terminal 93 is crimped after correcting and positioning the terminal position, the terminal position can be guaranteed before the crimping, and quality control is easy to implement.
