Wire end processing device

technical field

The invention relates to an electric wire terminal processing device.

Background technique

There is known an electric wire end processing device that exposes a core wire by performing stripping processing on an end portion of a covered electric wire whose size has been measured and cut in order to connect a predetermined terminal to the end of the electric wire. In recent years, there has been a further demand for such an electric wire end processing device to manufacture end processed electric wires of specifications with rubber plugs attached thereto (for example, refer to Patent Document 1). The electric wire terminal processing device disclosed in this patent document 1 includes a peeling unit and a rubber plug supply unit including a rubber plug delivery unit, a take-in mechanism, a rubber plug holder, a lifting unit, and the like.

As shown in FIGS. 12 and 13 , the rubber stopper delivery unit 501 of the rubber stopper supply unit in Patent Document 1 sends out a rubber stopper 503 supplied from a component feeder (not shown). The acquisition mechanism 505 acquires the rubber stoppers 503 one by one from the rubber stopper delivery unit 501 . The rubber plug holder 507 receives the rubber plug 503 from the acquisition mechanism 505 .

As shown in FIG. 12 , the rubber stopper delivery unit 501 includes a rubber stopper discharge pipe 509 which discharges the rubber stoppers 503 one by one, and a rubber stopper supply roller 511 which receives the rubber stoppers 503 from the rubber stopper discharge pipe 509 . On the peripheral surface of the rubber stopper supply roller 511 , an accommodation recess 513 for accommodating the rubber stopper 503 is formed. The accommodating recessed portion 513 is configured to be rotatable between a receiving posture for receiving the rubber stopper 503 and a delivery posture for turning 90° from the receiving posture to directly upward.

As shown in FIG. 12 , the acquisition mechanism 505 has: a pin 515 embedded in the inner peripheral portion of the rubber plug 503; an acquisition cylinder 517 that moves the pin 515 forward and backward; a cylinder holder 519 that holds the acquisition cylinder 517; and a rotation mechanism (Illustration omitted) Reciprocating rotation of the acquisition cylinder 517 within a range of 90° via the cylinder holder 519 . Whether or not the rubber stopper 503 has been picked up by the pin 515 of the picking mechanism 505 is detected by the photo-interrupter sensor 521 .

In the rubber plug supply unit of the electric wire terminal processing device having the above-mentioned configuration, the conveyed rubber plug 503 is conveyed to the rubber plug supply roller 511 . Then, the rubber stopper supply roller 511 which is in the receiving position in the initial state is rotated to be displaced to the rubber stopper handing over position. As a result, the fetching cylinder 517 lowers the pin 515 and fits it into the rubber stopper 503 in the transfer posture. Next, the rubber stopper 503 is taken out by raising the pin 515 by the takeout cylinder 517 .

After the acquisition operation is completed, the pin 515 is displaced from the acquisition position to the handover position, and then to a position for handing over the acquired rubber stopper 503 to the rubber stopper holder 507 .

As shown in FIG. 13, the rubber stopper holder 507 has a pair of clamping partners 523 that are opened and closed by a pneumatic chuck. The clamping partner 523 has a half-moon-shaped holding recess 525 that holds the rubber stopper 503 . The acquiring mechanism 505 hands over the acquired rubber stopper 503 to the rubber stopper holder 507 . Then, after the transfer operation is completed and the pin 515 of the acquisition mechanism 505 retreats, the air cylinder of the lifting unit this time lowers the rubber plug holder 507 at the receiving height to the rubber plug insertion height.

With the rubber plug holder 507 lowered to the rubber plug insertion height, the unit mounting table is advanced. Due to the forward movement of the unit mounting table, the stripping unit (not shown) and the rubber plug delivery unit 501 approach the end side of the covered electric wire 527 at the same time. Therefore, the stripping blades that are open to each other are displaced to a position where the covered electric wire 527 is sandwiched therebetween. The rubber stopper holder 507 having finished the rubber stopper insertion operation opens its clamping partner 523 to release the rubber stopper 503 . Thereafter, return immediately to the receiving height by means of the lifting unit.

After the stripping blade of the stripping unit is displaced to the stripping position, the pneumatic chuck of the stripping unit works to close the stripping blade, and cut off the sheathed part of the sheathed electric wire 527 . After the cutting operation is completed, the unit mounting table is reset and moved backward while the peeling blade is kept closed, and returns to the initial position. With this returning operation, the chips cut by the stripping blade are pulled out from the covered electric wire 527 . Then, by opening the peeling blade, each part completes one cycle and returns to the initial state.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 3 , the configuration of an electric wire terminal processing device 11 according to an embodiment of the present invention is roughly divided into an electric wire fixing mechanism 15 that clamps and fixes the vicinity of the end of a covered electric wire 19 on the terminal processing device. position; rubber plug holder unit 17, which holds the rubber plug 59 mounted on the covered electric wire 19; peeling unit 25, which cuts off the covered part of the covered electric wire 19; table drive mechanism 27, which makes the rubber plug equipped with The unit mounting table of the plug holder unit 17 and the peeling unit 25 reciprocates; and the control mechanism 201 performs interlocking control of each unit.

The wire end processing device 11 has a base plate 29 formed of a metal plate of a predetermined thickness and having a predetermined strength. A fixing post 31 of the wire fixing mechanism 15 is fixed to the base plate 29 . A track groove 33 extending in a direction perpendicular to the covered electric wire 19 is formed on the upper surface of the fixing post 31 . As shown in Figure 4, a pair of left and right wire clamping parts, that is, a left wire clamping part 35 and a right wire clamping part 37, are arranged on the track groove 33, and the pair of wire clamping parts freely move along the track groove 33. approach or move away from each other. That is, the clamp claw 35a of the left wire clamp 35 and the clamp claw 37a of the right wire clamp 37 are opened and closed by an unshown clamp driver.

A pair of guide shafts 39 , a total of two pairs, are fixed to each of the left wire clamp 35 and the right wire clamp 37 . As shown in Figure 5, a pair of auxiliary clamping parts, that is, a left auxiliary clamping part 41 and a right auxiliary clamping part 43, are installed on the guide shaft 39, and the pair of auxiliary clamping parts are respectively opposite to the left wire clamping part 35. and the right wire clamping part 37 are freely approaching or away from.

The auxiliary clamp air cylinder 47 advances and retreats the auxiliary air cylinder drive shaft 49 in a direction along the axis 51 of the covered electric wire 19 by pressurized air. An auxiliary clamp guide plate 53 is fixed to the front end of the auxiliary cylinder drive shaft 49 . The auxiliary clamp guide plate 53 is formed with a sliding groove 54 on the upper edge thereof, and engages with the guide protrusions 42 and 44 protruding from the respective lower edges of the left auxiliary clamp 41 and the right auxiliary clamp 43 . That is, the slide groove 54 of the auxiliary clamp guide plate 53 guides the clamping claw 41 a of the left auxiliary clamp 41 and the clamping claw 43 a of the right auxiliary clamp 43 in directions to approach or separate from each other.

The clamping claws 35a of the left electric wire clamping member 35 and the clamping claws 37a of the right electric wire clamping member 37 clamp the covered electric wire 19 from the direction perpendicular to the axis, and restrict the movement of the covered electric wire 19 in the direction along the axis 51 , fix the covered electric wire 19 in a clamped state. On the other hand, in the state where the left electric wire clamping part 35 and the right electric wire clamping part 37 clamp and fix the covered electric wire 19, the clamping claw 41a of the left auxiliary clamping part 41 and the clamping of the right auxiliary clamping part 43 The clamping claw 43 a is relatively movable in a direction along the covered electric wire 19 , and guides the covered electric wire 19 . That is, when the end of the covered electric wire 19 is inserted through the rubber plug 59, the left auxiliary clamp 41 and the right auxiliary clamp 43 guide the covered electric wire 19 so that the covered electric wire 19 is not bent due to insertion resistance (not will bend).

Therefore, the electric wire fixing mechanism 15 can hold and fix the vicinity of the end of the covered electric wire 19 at the terminal processing position.

In addition, the outer diameter of the large-diameter portion 59a is set larger than the outer diameter of the small-diameter portion 59b. The rubber plug 59 positions the covered electric wire 19 in the electric wire insertion hole 61 provided on the central axis of the large-diameter portion 59a and the small-diameter portion 59b. In addition, a lip portion that is in close contact with the wire lead-out hole of the connector housing is provided on the outer peripheral surface of the large-diameter portion 59a over the entire circumference. The small-diameter portion 59b is crimped and fixed to the covered electric wire 19 by a crimping piece of a connection terminal not shown.

Furthermore, a stage drive mechanism 27 is provided on the base plate 29 . The table driving mechanism 27 has a table air cylinder 63 fixed to the base plate 29 . The table air cylinder 63 advances and retreats the table air cylinder drive shaft 65 using pressurized air. A unit mounting table 67 is fixed to the air cylinder drive shaft 65 for a table.

A movable wall portion 69 perpendicular to the base plate 29 and a guide plate portion 71 extending in a direction along the table cylinder drive shaft 65 are formed on the unit mounting table 67 . The guide plate portion 71 is slidably supported on the side of the base plate 29 by a linear guide.

Therefore, the table driving mechanism 27 can reciprocate the unit mounting table 67 along the extension of the axis line 51 of the covered electric wire 19 fixed to the electric wire fixing mechanism 15 .

The unit mounting table 67 mounts the rubber stopper holder unit 17 and the peeling unit 25 on the movable wall portion 69 . In addition, a coating portion suction pipe 73 for sucking the coating portion 57 removed from the covered electric wire 19 (peeled off) is connected to the unit mounting table 67 .

As shown in FIG. 6 , the rubber plug holder unit 17 of this embodiment has a holder base 21 , a bush 75 (see FIG. 3 ), a rubber plug holder 23 , a rubber plug guide 77 , and a guide cover 79 .

As shown in FIG. 7 , a linear slide groove 81 is formed on the holder base 21 . The slide groove 81 freely guides the rubber plug holder 23 to slide freely in the horizontal direction perpendicular to the axis 51 of the covered electric wire 19 . The hole 83 for rubber plug supply and the hole 85 for electric wire insertion are separately provided on the holder base 21 in the sliding direction of the rubber plug holder 23 . A female screw is formed in the hole 83 for supplying the rubber plug, and a bush 75 is screwed to the female screw, and the bush 75 serves as a connection portion of a rubber plug supply pipe 87 . A rubber plug supply unit 13 described below is connected to the bush 75 via a rubber plug supply pipe 87 .

The holder base 21 guides the rubber stopper holder 23 to the rubber stopper feeding position and the rubber stopper insertion position. The rubber stopper supply position refers to a position for inserting and supplying the rubber stopper 59 into a rubber stopper accommodating portion 89 described later of the rubber stopper holder 23 (see FIG. 11( a )). The rubber plug insertion position refers to a position where the electric wire insertion hole 61 of the rubber plug 59 accommodated in the rubber plug housing portion 89 is on the axis 51 of the covered electric wire 19 (see FIG. 11( b )).

The rubber plug housing portion 89 that holds the outer peripheral portion of the accommodated rubber plug 59 is formed through the rubber plug holder 23 and is coaxial with the electric wire insertion hole 61 of the rubber plug 59 . Thus, the rubber stopper holder unit 17 accommodates and holds the rubber stopper 59 in the rubber stopper accommodation portion 89 .

In the present embodiment, the rubber stopper housing portion 89 is composed of a stepped hole 91 pierced in the rubber stopper holder 23 and an annular rubber stopper guide 77 attached to the large diameter side of the stepped hole 91 . The inner diameter of the large-diameter side of the stepped hole 91 is formed substantially the same as the outer diameter of the rubber plug guide 77 , and the inner diameter of the small-diameter side is formed substantially the same as the outer diameter of the large-diameter portion 59 a of the rubber plug 59 . The inner diameter of the rubber stopper guide 77 made of POM (polyoxymethylene resin) is formed substantially the same as the outer diameter of the small-diameter portion 59b of the rubber stopper 59, and the small-diameter portion 59b can be held inside without rattling.

A slide drive plate 93 is suspended from the rubber stopper holder 23 . The slide driving plate 93 hangs downward from the cutout portion 84 of the slide groove 81 of the holder base 21 that slidably holds the rubber stopper holder 23 . An engaging groove 95 is formed at the lower end of the slide driving plate 93 , and the engaging groove 95 is engaged with a driving member of a slider driver (not shown) mounted on the unit mounting base 67 . The rubber stopper holder 23 is reciprocated between the rubber stopper supply position and the rubber stopper insertion position by the drive of the slider driver.

And, the rubber stopper holder 23 is positioned at the rubber stopper supply position by abutting the slide driving plate 93 on the one side surface 84 a of the notch portion 84 , and by making the slide driving plate 93 abut on the other side surface of the notch portion 84 . 84b, thereby being positioned at the insertion position of the rubber stopper.

At the stopper supply position, the stopper accommodating portion 89 of the stopper holder 23 coincides with the stopper supply hole 83 of the holder base 21 and the bushing 75 . At the stopper supply position, on the opposite side of the bush 75 across the stopper accommodating part 89, a stopper sensor (not shown) for detecting the presence or absence of the stopper 59 in the stopper accommodating part 89 is provided.

In this rubber stopper supply position, the sliding surface 97 of the rubber stopper holder 23 is arranged in the hole 85 for electric wire insertion of the holder base 21 . That is, the wire insertion hole 85 is closed by the sliding surface 97 . Therefore, the leading end of the covered electric wire 19 in the electric wire set state abuts against the sliding surface 97 . And, when the rubber plug holder 23 is slid to the rubber plug insertion position, the rubber plug accommodating portion 89 is arranged in the electric wire insertion hole 85 .

In the wire end processing device 11 of the present embodiment, the rubber plug holder unit 17 is detachable from the unit mounting base 67, so that the rubber plug holder 59 provided with the rubber plug accommodating portion 89 can be selectively used according to different sizes of the rubber plug 59. Various rubber stopper holders 23.

As shown in FIG. 6 , the guide cover 79 is fixed to the holder base 21 on which the rubber stopper holder 23 is arranged to slide freely on the slide groove 81 . The guide cover 79 restricts the dropout of the rubber stopper holder 23 from the slide groove 81 . At the same time, by fixing the guide cover 79 to the movable wall portion 69 , the entirety of the rubber stopper holder unit 17 is fixed to the unit mounting base 67 .

As shown in FIG. 1 , the bush 75 of the rubber stopper holder unit 17 is connected to the rubber stopper supply unit 13 via a rubber stopper supply pipe 87 . The rubber stopper supply unit 13 supplies the plurality of rubber stoppers 59 arranged side by side to the rubber stopper holder unit 17 using pressurized air. That is, in the rubber stopper supply pipe 87 between the rubber stopper supply unit 13 and the bush 75 , the plurality of rubber stoppers 59 are arranged coaxially. In this state, the rubber stoppers 59 are supplied (delivered) one by one from the side closest to the rubber stopper holder 23 to the rubber stopper accommodating portion 89 by pressurized air.

As shown in FIG. 7 , a vent hole leading to the outside of the holder base 21 is formed in the rubber stopper supply hole 83 of the holder base 21 that connects the rubber stopper accommodation portion 89 and the rubber stopper supply pipe 87 in communication. 99. The vent holes 99 allow the inside of the rubber plug housing portion 89 to pass through the rubber plug holder 23 and the outside of the holder base 21 .

As shown in FIG. 8 , a left peeling blade 107 and a right peeling blade 109 are detachably fixed on a pair of left cutter mounting plate 103 and right cutter mounting plate 105 respectively by screws 111 . The left stripping blade 107 and the right stripping blade 109 cut off the covered portion 57 of the covered electric wire 19 that is fixed to the electric wire fixing mechanism 15 and protrudes.

When the pair of V-shaped blades 113 of the left stripping blade 107 and the right stripping blade 109 move from the direction sandwiching the covered electric wire 19 , cuts can be formed at multiple locations in the outer circumferential direction of the covered electric wire 19 . Then, the peeling unit 25 moves away from the covered electric wire 19 relative to the covered electric wire 19 fixed to the electric wire fixing mechanism 15 in the state where the cut marks are formed. This movement is performed by the unit mounting stage 67 . As a result, the sheathed portion 57 of the sheathed electric wire 19 that is closer to the tip side than the portion where the notch is formed is removed. The conductor 55 of the covered electric wire 19 from which the covering portion 57 has been removed is exposed (see FIG. 11( d )). In this way, the covering of the covered electric wire 19 is performed.

The opening and closing drive mechanism 101 drives the opening and closing of the left peeling blade 107 and the right peeling blade 109 in a direction perpendicular to the covered electric wire 19 . As shown in FIG. 3 , the opening and closing drive mechanism 101 has a cutter slide rail 115 and an opening and closing drive driver 117 . The opening and closing drive driver 117 is fixed to the guide plate portion 71 . The opening and closing drive driver 117 supports the left knife mounting plate 103 and the right knife mounting plate 105 via the knife sliding rail 115, so that the left knife mounting plate 103 and the right knife mounting plate 105 can be slidably driven. Various driving mechanisms such as pressurized air, a linear motor, or a solenoid coil can be used for sliding driving of the left knife mounting plate 103 and the right knife mounting plate 105 by the opening and closing drive driver 117 .

The control mechanism 201 of the present embodiment performs interlocking control of each unit so that the rubber plug insertion operation of the rubber plug holder unit 17 and the peeling operation of the peeling unit 25 are performed by the reciprocating operation of the table driving mechanism 27 . The units are, more specifically, a clamp driver (not shown), an auxiliary clamp air cylinder 47 , a table air cylinder 63 , a slider driver (not shown), and the like. The control mechanism 201 includes, for example, a computer including a CPU and a storage unit, an interface, and sensors. In addition, the control mechanism 201 includes a control device (such as an air cylinder, a solenoid coil) operating under the control of a computer, various switches (such as a foot switch) as an input unit, and the like. In addition, instead of using a computer, the control mechanism 201 may use a programmable device.

The control means 201 starts to operate upon receiving input signals from input means and sensors, and executes processing according to predetermined input conditions. Thereby, control is carried out via control devices such as air cylinders and solenoid coils, so that the above-mentioned actuator for clamping, air cylinder 47 for auxiliary clamping parts, air cylinder 63 for table, driver for sliders, etc. perform predetermined operations at predetermined time points. .

Next, the operation of the wire end processing device 11 having the above-mentioned configuration will be described.
