For example, a twisting machine for twisting an end of a wire of patent document 1 includes: the electric wire twisting device includes a chuck that cuts a cut and holds a coating end portion that slides along an electric wire, a mechanism that twists the electric wire by rotating the chuck around an electric wire axis, a tube that houses the coating end portion, and a suction mechanism that sucks the tube to collect the coating end portion.

Problems to be solved by the invention
However, in the conventional wire twisting device, after the coated portion of the coated wire is slid by cutting a notch, the coated wire is once retracted, then moved in the wire radial direction, and transported to the front of the twister for twisting the end portion of the wire, and then the end portion tip is advanced in the wire longitudinal direction, and is accurately inserted into the center of the gap between the pair of claw members of the chuck. In particular, when the distance from the position where the coated electric wire is gripped to the end is long, the end tip is likely to be displaced due to bending, and therefore, the end tip must be correctly inserted between the pair of claw members in a state where the coated electric wire is gripped by the chuck. Therefore, the tip must be correctly inserted in consideration of the deflection of the wire tip, and the correct position control is required. Further, in order to insert the electric wire between the pair of claw members accurately, if the guide member of the electric wire is disposed on the near side or the openings of the pair of claw members are opened widely, the electric wire can be inserted reliably, but if the guide member is disposed, the number of components increases, the structure becomes complicated, and if the openings of the claw members are enlarged, extra time is required for the opening and closing operation. Further, after the coated portion of the coated electric wire is cut into the notch and slid, the coated electric wire is once retreated and then moved laterally, and is moved forward from the wire distal end side in the wire longitudinal direction and inserted between the claw members in the next twisting process, in which case the process time is extended by the amount of the advancement and retreat of the coated electric wire.

Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in fig. 4, the electric wire processing apparatus 1 according to the embodiment of the present invention has: a length measuring unit 2 having a front clamp 2 a; a cutting unit 3; a rear clamp 4 as a clamp portion; a torsion unit 5; a flux unit 6; a brazing unit 7; a terminal crimping unit 8; and moving means 9, 10 for moving the length measuring unit 2 and the rear clamp 4.
To briefly explain the processing flow of the coated electric wire 12, the coated electric wire 12 is fed by a predetermined amount in the direction of the arrow P along the electric wire supply line X by the length measuring unit 2, and the coated electric wire 12 is gripped by the front gripper 2a as a gripper portion.
After the end of the covered wire 12 on the front jaw 2a side is cut by the cutter unit 3, a peeling process is performed to expose the core wire of the end, and then the end is moved to the position of the terminal crimping unit 8, the terminal is crimped to the front end of the covered wire 12 by the terminal crimping unit 8, and then the front jaw 2a is returned to the initial position.
Thereafter, the gripping of the front clamp 2a is released, the coated wire is fed while measuring the length of the coated wire, and a predetermined length is fed out. Thereafter, the coated electric wire 12 is cut by the cutter unit 3 while being held by two clamps, i.e., the front clamp 2a and the rear clamp 4, and the coating portions 12b at both ends of the cut coated electric wire 12 are peeled. At this time, the coating portion 12b of the cut coated electric wire 12 held by the rear clamp 4 side does not fall off from the core wire portion 12a, and a so-called half-peeled state is obtained. The covering portion 12b may be in a peeled state.
Then, the covered wire 12 on the rear jaw 4 side is moved to the position of the twisting unit 5 by the moving unit 10, and the core 12a is twisted by the twisting unit 5 and the covering 12b is pulled out from the core 12 a.
Thereafter, the coated wires 12 are moved to the positions of the flux units 6, and the core portions 12a are immersed in the flux grooves 6a of the flux units 6.
Next, the coated electric wire 12 to which the flux liquid has adhered is moved to the position of the soldering unit 7, and the core portion 12a is immersed in the solder groove 7a of the soldering unit 7, so that solder adheres to the core portion 12 a. The coated electric wire 12 with the solder attached thereto is discharged to a predetermined wire discharge portion (not shown). Thereafter, as shown in fig. 4, the front tong 2a and the rear tong 4 are returned to the initial positions opposed to each other.
By repeating the above operations, the covered electric wire 12 is sequentially manufactured with the terminal crimped at one end and the solder attached at the other end.
Next, the wire twisting device 11 including the twisting unit 5, which is a feature of the present invention, will be described in detail.
As shown in fig. 1A to 3B, the twisting unit 5 of the electric wire twisting device 11 includes: a device rack (not shown); a rotating shaft 22 rotatably supported around a horizontal axis at an upper portion of the apparatus frame; a servo motor 23 provided at an upper portion of the apparatus stand; and an interlocking mechanism 24 for rotating the rotary shaft 22 forward and backward by forward and backward driving of the servo motor 23. The torsion unit 5 is provided with an opening/closing mechanism 25 driven by an opening/closing cylinder 25 a. Specifically, the telescopic motion of the open/close cylinder 25a is transmitted to the swing link 25b, the swing of the swing link 25b is linked to the open/close motion of the open/close link 25c, and the first member 26a and the second member 26b of the chuck section 26 connected to the open/close link 25c are openable and closable. In this way, the opening and closing operation of the open/close cylinder 25a opens and closes the chuck section 26, and the covered electric wire 12 in the half-peeled state or the peeled state conveyed by the rear clamp 4 is released from being held by the opening and closing operation.
The interlocking mechanism 24 includes a driving timing pulley 24a pivotally supported on an output shaft 23a of the servo motor 23, a driven timing pulley 24b integrally rotatably attached to the rotary shaft 22, and a timing belt 24c wound around these pulleys, and by these structures, the rotary shaft 22 can be rotationally operated in any direction.
By rotating the rotary shaft 22, the chuck 26 can be switched between a receiving posture in which the first member 26a and the second member 26b are opened vertically and have a horizontal gap 26c extending in the horizontal direction and a chip discharging posture in which the first member 26a and the second member 26b are opened horizontally and have a vertical gap (not shown) extending in the vertical direction. As shown in fig. 2A, inclined surfaces 26d are formed on the insertion side of the coated electric wire 12 of the first member 26a and the second member 26b so that the distance between the gripping positions toward the end portions is narrowed.
The control unit 36 is also provided for controlling the driving of the servo motor 23, and controls the amount of rotation driving of the servo motor 23, the rotation speed, the stop time, the timing of supplying high-pressure air, and the like in accordance with the input of operation data to the operation panel 3 for inputting various operation data. By changing the input of the operation data, the rotation driving amount, the rotation speed, the stop time, the air blowing timing, and the like can be freely changed and adjusted. The control unit 36 is configured to insert the end of the coated wire 12 from the direction intersecting the longitudinal direction of the coated wire 12 into the horizontal gap 26c extending in the horizontal direction, which is vertically opened, of the first member 26a and the second member 26b of the twisting unit 5 by the rear clamp 4, and to rotate and twist the coated wire 12 while sandwiching the end of the coated wire 12 by closing the first member 26a and the second member 26b by the twisting unit 5.
The electric wire twisting device 11 further includes a coating dust discharging portion 27, and the coating dust discharging portion 27 blows off the dust of the coating portion 12b from below by blowing air in a state where the first member 26a and the second member 26b are left and right opened after the chuck portion 26 twists the core wire portion 12 a. Specifically, the coating dust discharge unit 27 includes an air pipe 27a connected to the upper side of the chuck unit 26 and a nozzle unit 27b connected to the air pipe 27a, and high-pressure air is discharged from the nozzle unit 27b to the first member 26a and the second member 26b by opening and closing a valve connected to a compressor, not shown, by the control unit 36. For example, a container or the like for collecting the chips of the coating portion 12b may be provided below the chuck portion 26.
Wire handling method
Next, the main part of the electric wire processing method according to the present embodiment will be described with reference to fig. 5. In the present embodiment, the control unit 36 controls the electric wire processing apparatus 1 in accordance with an input from the operation panel 37.
First, in each of the above-described upstream steps, after the terminal is crimped to the front side of the coated electric wire 12, the coating 12b on the rear side is cut into a notch so that the coating 12b is slightly displaced and is in a half-peeled state.
Next, in the holding step, the vicinity of the end of the semi-stripped coated electric wire 12 is held by the rear clamp 4.
Next, the first member 26a and the second member 26b of the torsion unit 5 are opened up and down to be in a torsion-ready state in which a horizontal gap 26c extending in the horizontal direction is formed.
Next, as a clamping step, in step S01 of fig. 5, a twist request is output. Then, the half-peeled portion of the covered electric wire 12 held by the rear gripper 4 is horizontally moved from the direction intersecting the longitudinal direction of the electric wire and inserted into the horizontal gap 26 c.
Next, in step S02, the first member 26a and the second member 26b are closed to grip the half peeled portion. At this time, as shown in fig. 2A, since the shapes of the first member 26a and the second member 26b on the entry side of the covered electric wire 12 are formed so as to narrow the interval toward the gripping position of the covered electric wire 12, the covered electric wire 12 can be inserted more smoothly while being guided by the pair of inclined surfaces 26d when the covered electric wire 12 is inserted. Therefore, the gripping error of the covered electric wire 12 can be further reduced.
Next, in step S03, the rear clamp 4 performs tension adjustment. This is because the core wire portion 12a cannot be twisted when the covered wire 12 is not appropriately pulled.
Next, in the twisting step of step S04, the first member 26a and the second member 26b gripping the end of the covered wire 12 are rotated about the rotation shaft 22 to twist the end of the covered wire 12. At the same time, the backward timing of the rear clamp 4 in the wire longitudinal direction is set.
Next, in step S05, when the timer is ended, the rear clamp 4 is notified of the retreat.
Next, in step S06, the rotation of the rotary shaft 22 is completed, the movement of the rear clamp 4 in the wire longitudinal direction is completed, and the first member 26a and the second member 26b are opened.
Next, in step S07, it is determined whether or not the mode is the half peeling mode. If the mode is the half peeling mode, the process proceeds to step S08, and if the mode is not the half peeling mode, the coated chip discharging step is not required, and the process proceeds to step S11.
In step S08, as the covering dust discharge step, the twisting unit 5 twists the core wire portion 12a and then brings the rotary shaft 22 into the air discharge position, that is, a state in which the first member 26a and the second member 26b are arranged in a left-right open state.
Next, in step S09, the air for gas discharge is operated and an air timer is set. Thus, high-pressure air is pushed out from the nozzle portion 27b, and the chips in the covering portion 12b are blown downward. By providing a container or the like for collection at the lower side, the chips of the covering portion 12b can be easily and quickly collected. In this case, a covering dust suction step may be included, in which the twisting unit 5 twists the core portion 12a and then sucks the dust in the covering portion 12b downward in a state where the first member 26a and the second member 26b are opened to the left and right. In this case, too, the chips of the covering portion 12b can be easily and quickly collected.
Next, at step S10, when the air timer ends, the supply of air is stopped, and the rotary shaft 22 is returned to the horizontal state in which the first member 26a and the second member 26b are arranged vertically.
Next, the rotating shaft 22 is reset at step S11, and preparation is made with respect to the next covered electric wire 12.
Next, the first member 26a and the second member 26b are opened up and down at step S12, preparation for the next twist work is made, and the process returns to step S01.
In this way, in the present embodiment, when the end of the coated electric wire 12 is half-peeled and inserted between the first member 26a and the second member 26b of the twisting unit 5 in order to twist the end of the coated electric wire 12, the coated electric wire 12 is moved horizontally and in the direction intersecting the longitudinal direction of the electric wire without being moved largely forward and backward, and the horizontal gap 26c between the first member 26a and the second member 26b opened up and down is inserted, so that the process time can be shortened. Further, it is not necessary to accurately position the tip of the end portion as in the conventional art, and even if the tip is slightly bent, the tip can be moved horizontally and in a direction intersecting the longitudinal direction of the wire as it is, so that the control is extremely easy. Further, the solder can be attached to the end of the twisted covered wire 12 with high accuracy in a short process.
Therefore, according to the electric wire twisting device 11 of the present embodiment, the twisting work of the core wire portion 12a can be accurately and efficiently performed.
(other embodiments)
The present invention may be configured as follows with respect to the above-described embodiment.
That is, in the above embodiment, the terminal is crimped and then the solder is attached by applying the twist, but conversely, the terminal may be crimped on the rear side after the solder is attached by applying the twist on the front side. The present invention can also be applied to the electric wire processing apparatus 1 in which solder is attached to both the front side and the rear side.
In the above embodiment, the coating dust discharging portion 27 is provided to blow the coating portion 12b downward, but a coating dust suction portion may be provided to suck the dust of the coating portion 12b downward in a state where the first member 26a and the second member 26b are opened in the left and right directions after the chuck portion 26 twists the core wire portion 12 a. In this case, the chips can be reliably collected by providing an air pipe below and sucking the chips in the covering portion 12 b. In this case, the chips may be sucked in from an oblique or lateral direction without being sucked directly downward.
The above embodiments are merely preferred examples in nature and are not intended to limit the scope of the present invention, its applications, or uses.
