Abstract

PURPOSE:To perform terminal crimp surely at high speed in one operation, by displacing an upper metal mold and a lower mold in complete synchronism with each other. CONSTITUTION:When a rotary shaft 43 is rotated by drive force from a motor 38, a lower mold holding member 36 for holding a lower metal mold 32 is vertically displaced by the operation of an eccentric cam fixed on the rotary shaft 43. Rotation of the rotary shaft 43 is transferred to a rotary shaft 49 through a timing belt 48. Rotation of the rotary shaft 49 provides operation of a crank means comprising a crank arm 61 and links 53, 55, etc., so that an upper mold holding member 51 for holding an upper metal mold 31 is vertically displaced. Thus, the upper metal mold 31 and the lower metal mold 32 are displaced in complete synchronism so as to meet with each other at the datum level position 30 where the end of the wire for crimping a terminal is held.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal crimping device for crimping a terminal to an end of an electric wire constituting a wire harness of an automobile or a copying machine.

[0002]

2. Description of the Related Art The process of manufacturing a wire harness constructed by bundling a plurality of covered electric wires includes measuring and cutting the electric wire length, peeling the electric wire end, and peeling the electric wire. Terminal crimping process of crimping the terminal to the end conductor,
It includes a terminal inserting step of inserting the terminal into the connector housing, a binding step of binding the electric wires to which the connector is attached, and the like.

A general terminal crimping device for crimping a terminal to an electric wire has a lower mold placed on a press table and an upper mold provided so as to face the lower mold. The terminal is placed on the lower mold, the electric wire is arranged on the terminal, and the upper mold is displaced toward the lower mold. Since the wire harness is composed of a large number of covered electric wires, the electric wires and the terminals must be crimped over a large number of times. Therefore, there has been conventionally proposed a device for automatically performing terminal crimping a large number of times.

[0004] For example, a typical conventional device is provided with an electric wire holding means for holding a plurality of electric wires whose ends are peeled off in a line at a fixed interval, and the electric wire holding means is arranged in the arranging direction of the electric wires. By being intermittently conveyed, the ends of the wires to which the terminals are to be crimped are sequentially supplied to the intermediate position between the upper mold and the lower mold. Further, terminals are sequentially supplied to the lower mold so as to be synchronized with the supply of electric wires. When the upper mold is displaced toward the lower mold after the terminals and the electric wires are supplied, the electric wires come into contact with the upper mold and are guided to the terminals on the lower mold during the displacement of the upper mold. From this state, by further displacing the upper mold toward the lower mold, the terminals are deformed and the crimping is achieved. By repeating such an operation, it is possible to automatically crimp the terminal a plurality of times.

By the way, recently, after crimping the terminals,
A technique for automatically inserting this terminal into a connector housing has been proposed. In such automatic terminal insertion technology, the proximal end of the terminal and the electric wire in the vicinity of the terminal are gripped, and when the tip of the terminal is inserted into the connector housing, the grip of the proximal end of the terminal is released. The insertion of the terminal is achieved by displacing the electric wire gripping part, which grips the electric wire in the vicinity of, toward the connector housing. That is, the electric wires held in the electric wire holding means in an aligned state at regular intervals are removed, and the terminals crimped to the tips are inserted into the connector housing.

However, when the terminal crimping device is used in which the end portion of the wire is located at the intermediate position between the upper die and the lower die as described above and only the upper die is displaced downward, the wire is bent during crimping. It will be. It is difficult for the mechanical device to accurately grasp the bent electric wire in this manner, and therefore it may not be possible to properly insert the terminal into the connector housing. Moreover,
Since crimping is performed with the electric wire bent, crimping may be defective.

A typical prior art that solves this problem is
It is disclosed in JP-A-1-313870. In this prior art, the lower die held on the press table before the crimping is moved up to the position of the electric wire. That is, first, the press base is moved upward to bring the wire into contact with the terminal held by the lower mold, and then the upper mold is displaced downward to achieve crimping. Since the press base is heavy, it can be displaced up and down by a cylinder using air pressure or the like.
The upper mold is driven by using a motor or the like as a drive source.

In this structure, since the crimping is performed while the electric wire is kept at the initial position, the electric wire is not bent. For this reason, not only the occurrence of problems in the subsequent terminal inserting step can be prevented, but also the reliability of terminal crimping can be enhanced.

[0009]

However, in this prior art, since the operation is performed in two steps of upwardly displacing the press base and then downwardly displacing the upper die, a new problem that the crimping speed becomes slower occurs. Occurs. Moreover, since the entire press table having a considerable weight is displaced upward, the press table inevitably slows down, which also causes deterioration of the crimping speed. If the crimping speed is slow in this way, the time required for crimping a large number of times is extremely increased, and the deterioration of productivity cannot be avoided.

In order to prevent the terminal crimping operation from becoming a two-step operation, it is conceivable to synchronize the upward displacement of the press table and the downward displacement of the upper die with each other. Since it is different from the driving source of the upper mold, it is difficult to synchronize. Therefore, if the upward displacement of the press table and the downward displacement of the upper mold are not synchronized, the upper mold and the lower mold cannot meet at the position where the wire is held, and the terminal There is a definite problem that it becomes impossible to crimp.

Therefore, an object of the present invention is to solve the above-mentioned technical problems, to improve the crimping speed remarkably, and to further securely crimp the terminal without bending the electric wire. It is to provide a terminal crimping device capable of performing the above.

[0012]

The terminal crimping device according to claim 1 for achieving the above object is characterized in that the terminal and the electric wire are sandwiched between the upper die and the lower die to deform the terminal. In a terminal crimping device for crimping an electric wire, an electric wire holding means for holding a crimped portion of the electric wire in a floating state at a predetermined position between an upper mold and a lower mold, and a terminal so that the terminal is positioned on the lower mold. , A driving mechanism for synchronously displacing the upper mold and the lower mold so that the upper mold and the lower mold reach the above-mentioned predetermined positions almost at the same time, and a driving force for applying a driving force to the driving mechanism One drive source is included.

According to the above construction, the upper die and the lower die are displaced in synchronism with each other toward the predetermined position where the crimped portion of the electric wire is held in a floating state, whereby crimping is achieved. .. The upper die and the lower die are displaced in perfect synchronization by a drive mechanism to which a drive force from a single drive source is applied.
As a result, rather than the two-step operation of the prior art,
Since the crimping of the terminal can be achieved with one operation,
The terminal crimping speed is improved. Moreover, since the displacements of the upper mold and the lower mold are completely synchronized, the upper mold and the lower mold can be reliably brought into contact with each other at the predetermined position, whereby the terminals can be crimped reliably. Further, the crimped portion of the electric wire is not displaced from the predetermined position, so that the crimping of the terminal can be achieved without causing the electric wire to bend.

The drive source may be composed of a motor. In this case, the drive mechanism includes a cam for displacing the lower mold toward the upper mold by receiving a rotational force from the motor, and the motor. And a crank mechanism for displacing the upper die toward the lower die by obtaining the rotational force from the. In the terminal crimping device according to claim 3, the electric wire holding means can hold the crimped portions of a plurality of electric wires at a constant interval, and the electric wire holding means holds the plurality of electric wires. A transport means for transporting the wire holding means so as to sequentially supply the wire between the upper mold and the lower mold; and a drive control means for intermittently driving the drive source each time the wire is supplied. Characterize.

According to this structure, since the electric wires are sequentially supplied between the upper mold and the lower mold, it is possible to continuously crimp the terminals to a large number of electric wires. In this case, since the drive source applies the drive force to the drive mechanism in synchronization with the supply of the electric wire by the operation of the drive control means, the terminals can be crimped well. The terminal crimping device according to claim 4, wherein the drive mechanism is attached to a fixedly arranged main body portion and slidable in a predetermined direction with respect to the main body portion, and the lower die holding portion holds the lower die. It is characterized in that it includes a member and an upper mold holding member that is attached to the main body so as to be slidable in the predetermined direction and holds the upper mold.

According to this structure, the lower die holding member and the upper die holding member, which are slidably attached to the fixedly arranged main body portion, are displaced toward each other so that the terminals are crimped. The lower mold holding member and the upper mold holding member separated from the main body portion in this way can be configured to be lightweight. Therefore, unlike the conventional configuration that vertically displaces the heavy press table as a whole, it is sufficient to slide and displace the relatively lightweight upper die holding member and lower die holding member. Can be done.

The wiring board 2 has a pin board 2A on which wiring pins are erected, and a base plate 2B that holds the pin board 2A and that is transported by the transport mechanism 3. On the surface of the pin board 2A, a plurality of wiring pins 5 are provided upright at positions corresponding to a desired wiring pattern. The wire laying device (not shown) lays the electric wire 1 by winding the electric wire 1 around the wiring pin 5 in order. On the side edge 4 of the base plate 2B facing the terminal crimping device M, an electric wire clamp 6 which is an electric wire holding means for holding the ends of the electric wire 1 at a constant interval is arranged.

The construction of the wire clamp 6 is shown enlarged in FIG. That is, the electric wire clamp 6 includes the clamp member 7 shown in FIG.
It is configured by being attached to a long frame 10 shown in FIG. 5 (b) at a constant pitch. Note that FIG. 5B is a cross-sectional view seen from a cross section that intersects the longitudinal direction of the frame 10.

Semi-cylindrical recesses facing each other are formed at the base end of each sandwiching piece 8, and the recesses form holes 8a. A cross section of the frame 10 that intersects in the longitudinal direction is formed in a substantially U shape, and a mounting hole 14 formed in a pair of rising portions 10a of the frame 10 and a hole 8a formed by the recess of the pair of clamp members 7 are formed. And mounting pins 11 are inserted therethrough. Further, a bolt 13 is screwed into an inner bottom surface 10b of the frame 10 by inserting it through a hole 12 formed in the bottom portion of the leaf spring 9.

A positioning groove 15 is formed in the bottom of the frame 10 along the longitudinal direction, and this positioning groove 15 is fitted into a positioning projection 16 formed on the side edge 4 of the base plate 2B, and in this state it is approximately L. Character-shaped mounting member 1

The end portion of the electric wire 1 is gripped so as to protrude from the wire by a certain length. In the base plate 2B, on the pinboard 2A side of the electric wire clamp 6, a parallel comb 18 for arranging electric wires that are guided while being fan-shaped diffused from the pinboard 2A in a parallel state is arranged as indicated by reference numeral 20. ing. Due to the actions of the parallel comb 18 and the wire clamp 6, the ends of the plurality of wires 1 are separated from the side edge 4 of the base plate 2B.
In, they are aligned in parallel with each other at a constant pitch. In FIG. 5, 19 is a member for keeping the height of the electric wire constant.

FIG. 1 is a front view of the terminal crimping device M, and FIG. 2 is a right side view of the configuration shown in FIG. The end portion of the electric wire 1 held in a floating state by the electric wire clamp 6 is conveyed by the conveying mechanism 3 while maintaining the reference level position indicated by reference numeral 30. This reference level position 30
The upper die 31 is disposed on the upper side and the lower die 32 is disposed on the lower side with the sheet sandwiched therebetween. A plurality of terminals 33 to be crimped to the end portion of the electric wire 1 are joined together into a band shape, and are sequentially supplied one by one onto the lower die 32 by the terminal feeding mechanism 70. The supplied terminal 33 is held so as to be positioned on the lower mold 32 by the terminal feeding mechanism 70 and a belt-shaped body configured by connecting the terminal 33.
In this way, the terminal feeding mechanism 70 and the like constitute the terminal holding means.

The lower die 32 is held by a lower die holding member 36 slidably attached to a rising portion 35A of a substantially L-shaped main body 35 fixedly arranged. The rotary shaft holding portion 37 is provided on the bottom portion 35B of the main body portion 35.
The rotary shaft 43 is supported by the rotary shaft holder 37 via an appropriate bearing. Rotating shaft 4
3 includes a motor 38 as a drive source and a gearbox 3
The rotational force via 9 is transmitted via the pulley 40, the belt 41, and the pulley 42. The gear box 39 has a clutch inside and is configured to control the output of the driving force of the motor 38.

An eccentric cam 44 is fixed to an intermediate portion of the rotary shaft 43. The eccentric cam 44 supports the lower die holding member 36 via a roller follower 45 attached to a holding body 46 that abuts a lower end portion of the lower die holding member 36, as shown in an enlarged manner in FIG. 6. ing. Therefore, the lower mold holding member 36 moves up and down as the rotary shaft 43 rotates. The eccentric cam 44 is configured such that the lower die 32 reaches the reference level position 30 at the top dead center in the vertical movement of the lower die holding member 36.

The lower die holding member 36 is fixed to a slide plate 66, and this slide plate 66 is slidably attached to a rising portion 35A of the main body portion 35 via a linear guide 65. Another pulley 47 is attached to the end of the rotating shaft 43 opposite to the pulley 42. A timing belt 48 is wound around the pulley 47, and the timing belt 48 is further wound around a pulley 50 fixed to a rotary shaft 49 supported by a rising portion 35A of the main body portion 35 through an appropriate bearing. It is hung.

On the inner surface of the rising portion 35A of the main body portion 35, an upper die holding member 51 holding the upper die 31 is vertically slidably attached. A pair of links 53 is attached to the upper die holding member 51 by a shaft 52. The link 53 is connected to another pair of links 55 by a shaft 54, and the link 55 is attached to a slide member 60 by a shaft 56. Slide member 60
Is slidably attached to the inner surface of the rising portion 35A of the main body portion 35. Above the slide member 60, a servo motor 58 mounted on a motor mounting portion 57 fixed to the rising portion 35A of the main body portion 35 is provided. The driving force of the servomotor 58 is given to a screw rod 59 having a screw thread on the outer peripheral surface thereof.
It is screwed into a screw hole formed in the slide member 60. Therefore, by rotating the servo motor 58 in the forward and reverse directions, the slide member 60 is vertically displaced, and the slide member 6 is moved.
The position of 0 can be adjusted.

The upper die holding member 51 holding the upper die 31 in this way includes the links 53 and 55, the slide member 60,
It is supported by the body portion 35 via the screw rod 59 and the motor mounting member 57. One end of a crank arm 61 is connected to an intermediate portion of a shaft 54 that connects the links 53 and 55. The other end of the crank arm 61 is connected to the eccentric shaft 62 attached to the intermediate part of the rotary shaft 49 described above.
The axis of the eccentric shaft 62 is deviated from the axis of the rotating shaft 49 by a distance R. Therefore, when the rotating shaft 49 rotates, the eccentric shaft 6
2 is displaced by a maximum of 2R. As a result, the shaft 54 connected to the eccentric shaft 62 via the crank arm 61 is displaced in the substantially horizontal direction by the distance 2R, and as a result, the links 53 and 55 are in the bent state shown in FIG. The links 53 and 55 are displaced between the straight lines. As a result, the upper die holding member 51 is vertically displaced. The bottom dead center of this vertical displacement is the upper die holding member 51.
It is a position where the upper mold 31 held by is completed the crimping of the terminal 33, that is, a position where the upper mold 31 reaches the reference level position 30.

As described above, the crank arm 61, the eccentric shaft 62, the links 53, 55 and the like constitute a crank mechanism. FIG. 7 is an enlarged front view showing the structure of the terminal feeding mechanism 70. The terminal feed mechanism 70 includes a swing member 73 that swings around a support shaft 72 attached to the lower die holding member 36 with bolts 71 and the like, and the swing member 7.
The feed claw 7 swingably attached to the distal end portion 73a of the No. 3
4 and. The tip end of the feed claw 74 extends toward the lower die 32, and the base end thereof is urged downward by a coil spring 75 shown in a simplified manner in FIG. 7.

On the back surface of the swing member 73, a slide hole 76 having a bent shape is formed. A shaft 77 fixed to the main body portion 35 is slidably inserted into the slide hole 76. Therefore, the lower die holding member 3
When the fulcrum shaft 72 is vertically displaced following the vertical displacement of 6,
An external force is applied to the peripheral surface of the slide hole 76 in the rocking directions R2 and R3, and as a result, the rocking member 73 rocks. At this time, the feed claw 74 simultaneously swings, and its tip engages with a gap (not shown) formed between the terminals 33 connected in a strip shape. In this engaged state, the feed claw 74 swings in the direction of arrow R3, whereby the terminal 33 is supplied to the lower mold 32.

In FIG. 7, reference numeral 78 is a guide member for guiding the electric wire 1 held by the electric wire clamp 6. That is, since the electric wire 1 extending from the electric wire clamp 6 may be slightly deformed, the terminal 33 is guided with the guide member 78 accurately guiding the electric wire 1 to a position directly above the lower mold 32. That is, the crimping is performed.

The operation of the terminal crimping device of this embodiment will be described in more detail with reference to FIGS. 1 and 2. The clutch in the gear box 39 operates in response to a predetermined input signal derived each time an electric wire for crimping the terminal is supplied between the upper mold 31 and the lower mold 32, and the rotary shaft is rotated. 43 is rotated once. That is, the gearbox 39 stops the output of the driving force when the rotating shaft 43 is rotated once.

As a result, the rotating shaft 43 rotates only once in response to one terminal crimping operation. As a result, the eccentric cam 44 rotates once, so that the lower die holding member 3
6 is displaced back and forth only once between the bottom dead center and the top dead center. In this way, the drive control means is constituted by the gear box 39 and the like. Since the rotation of the rotary shaft 43 is transmitted to the shaft 49 via the timing belt 48 and the like, the crank arm 61 operates in synchronization with the operation of the lower die holding member 36. As a result, the upper die holding member 51 is lowered and displaced in synchronization with the lower die holding member 36 being displaced upward, and the upper die holding member 51 is synchronized with the lower die holding member 36 being displaced downwardly.
Is displaced upwards.

As described above, the lower die 32 reaches the reference level position 30 when the lower die holding member 36 is displaced to the top dead center, and the upper die is displaced when the upper die holding member 51 is displaced to the bottom dead center. The mold 31 reaches the reference level position 30. Therefore, the end portion of the electric wire 1 is held in the floating state at the reference level position 30.
Then, the upper die 31 and the lower die 32 meet each other. Therefore, while the electric wire 1 is held in the initial position, the terminal 33 held on the lower mold 32 is deformed, and the terminal 33 and the end portion of the electric wire 1 are crimped.

As described above, in the terminal crimping device M of this embodiment, the upper die 31 and the lower die 32 receive the driving force from the motor 38, which is a single drive source, and are displaced in perfect synchronization. To do. For this reason, unlike the above-described prior art in which the upward displacement of the lower mold and the downward displacement of the upper mold are performed in two stages, the upper mold 31 and the lower mold 32 are driven simultaneously and 1 The crimping of the terminal 33 is achieved by a single operation. Therefore, the terminal crimping can be performed at extremely high speed.

Moreover, since the upper mold 31 and the lower mold 32 are displaced in perfect synchronization in response to the driving force from the motor 38 which is a single driving source, the end portion of the electric wire 1 is in a floating state. Upper die 31 and lower die 3 at the held reference level position 30
It is possible to meet 2 with certainty. As a result, the terminals 33 can be securely crimped. Further, since the position of the electric wire 1 does not move during the terminal crimping process, naturally the end portion of the electric wire 1 does not bend. For this reason, in the case where after the terminal crimping, the crimped terminal 33 and the end portion of the electric wire 1 are gripped by a mechanical device and the terminal inserting step of inserting the terminal into the connector housing is automatically performed, the terminal 3
3 and the end portions of the electric wire 1 can be surely gripped to surely insert the terminal.

Further, in this embodiment, the lower die holding member 36, which is relatively lightweight, is slid along the main body portion 35, instead of displacing the entire heavy press stand as in the prior art described above. I have to. For this reason, the upward displacement of the lower die holding member 36 and the downward displacement of the upper die holding member 51 that proceed in synchronization with each other can be performed at high speed. Therefore, the crimping speed can be further increased.

The present invention is not limited to the above embodiment. For example, in the above embodiment, the case where the terminal is crimped to the end of the electric wire has been described, but the terminal crimping device of the present invention is also applied to the case where the coating in the middle of the electric wire is removed and the terminal is crimped to this portion. can do. In addition, various design changes can be made without changing the gist of the present invention.

[0039]

As described above, according to the terminal crimping device of the present invention, the upper die and the lower die are displaced in synchronism with each other, whereby crimping of the terminal is achieved. Therefore, the crimping of the terminal can be achieved by one operation. As a result, the terminal crimping speed is significantly improved. Further, since the upper die and the lower die are displaced in perfect synchronization by receiving a driving force from a single drive source, the upper die and the lower die can be reliably met. Therefore, the terminals can be securely crimped.

Further, the crimped portion of the electric wire is not displaced from the initial position, so that the crimping of the terminal can be achieved without bending the electric wire. Therefore, no trouble occurs in the subsequent process. Further, a lower die holding member holding the lower die and an upper die holding member holding the upper die are slidably attached to a fixedly arranged main body in a predetermined direction, and the lower die holding member and the upper die are driven by a drive mechanism. If the mold holding members are displaced close to each other, the relatively lightweight upper mold holding member and lower mold holding member are slid and displaced at high speed, so that the terminals can be crimped at a higher speed.
