Description
The present application is a divisional application of an application having an application date of 2017, 3 and 13, and an application number of 201710145349.8, entitled "solder member, and electric wire processing apparatus and electric wire processing method provided with the same".
Technical Field
The present invention relates to a brazing material unit for adhering a brazing material to an end portion of a coated electric wire in which a core wire portion is exposed, an electric wire processing apparatus including the brazing material unit, and an electric wire processing method.
Background
In such an electric wire processing apparatus, after a coating portion at an end portion of a coated electric wire is peeled off, a flux liquid is applied to an exposed core wire portion, and then the core wire portion is inserted into a solder pot to apply a solder to the core wire portion. When the core wire portion is inserted into the brazing material groove, the molten brazing material in the brazing material groove is in a high-temperature molten state of about 300 ℃, and if the core wire portion in a state where the flux liquid is adhered is inserted into the high-temperature brazing material groove, there may be a problem that the flux liquid evaporates in the brazing material to generate bubbles, and the adhesion length of the brazing material to the core wire portion becomes unstable due to the bubbles and the scattering of the brazing material due to the bubbles, or the brazing material scatters to adhere to the coating portion.
For this reason, for example, in patent document 1, in a state (standby posture) in which an end portion of a covered electric wire connected by a front clamp is held in a horizontal state by a grip portion of a rotating arm, the rotating arm is rotated toward a solder bath at a predetermined speed and is tilted down (insertion posture). As a result of this rotation, as shown in fig. 11, when the tip portion of the core wire portion is inserted at a predetermined speed of acceleration or deceleration, the drive of the servo motor is temporarily stopped (first stopped) in the tip portion inserted state. By this first stop, the flux liquid adhering to the core wire portion is evaporated and dried by the heat of the solder melt. After a predetermined stop time has elapsed, the servomotor is driven again, the rotor arm is further rotated at a predetermined speed to fall down, and the driving of the servomotor is stopped again in the insertion posture of the rotor arm (second stop). The remaining core wire portions are inserted at a predetermined insertion speed by the rotation, and the core wire portions are inserted to predetermined positions corresponding to the solder attachment length in the solder melt in the solder pot. After a predetermined time has elapsed from the second stop, the servo motor is driven in the reverse direction, and the swing arm is operated to swing at a predetermined speed to rise, and returns to the initial standby posture. Thus, the variation of the solder adhering length with respect to the wire core portion and the adhesion of the solder to the coating portion are prevented, and the processing quality in the solder adhering process is improved.

Problems to be solved by the invention
However, in the solder attaching method of patent document 1, as shown in fig. 11, since the solder is once stopped after being immersed in the solder, and then is again accelerated and decelerated to be inserted into the solder, the end of the covered electric wire on the side opposite to the exposed portion side, which is sandwiched by the sandwiching portion, is greatly shaken to cause disturbance of the crimp terminal or the electric wire, and there is a possibility that damage may occur due to contact with peripheral equipment. Further, since the insertion is performed again after the stop once, the process time becomes long, and the efficiency is deteriorated.
Disclosure of Invention
The present invention has been made in view of the above circumstances, and an object of the present invention is to perform solder adhesion in as short a time as possible, and to perfectly adhere a solder to an end portion of a covered electric wire in which a core wire portion is exposed while suppressing damage to a crimp terminal or an electric wire.
Means for solving the problems
In order to achieve the above object, according to the present invention, when approaching the brazing material groove, the exposed core wire portion is gradually immersed in the brazing material groove while decelerating the clamping portion and reducing the deceleration without accelerating.
Specifically, the invention according to the first aspect is premised on an electric wire processing method in which a covering portion of a covered electric wire is removed, and a brazing material is attached to an end portion of the covered electric wire in which a core wire portion is exposed.
The wire processing method further includes:

an acceleration approach step of causing the clamp portion to approach a brazing material groove located in front of and below the clamp portion while accelerating;
a deceleration immersion step of immersing the flux groove after approaching while decelerating after the acceleration approach step,
and comprises:
in the deceleration immersion step, the deceleration is further reduced at a deceleration changing point arbitrarily set during deceleration without accelerating the nip portion again,
a step of immersing the exposed core wire portion into the brazing material bath for a predetermined length, and then stopping the clamping portion;
and a retracting step of raising the gripping portion upward after the deceleration immersing step.
According to the above configuration, since the exposed core wire portion is brought close to the solder groove without stopping and gradually brought close to the solder, the operation of the opposite end portion of the covered electric wire can be reduced without a drastic operation change, and damage to the crimp terminal or the electric wire can be suppressed. Therefore, it is not necessary to stop the brazing material temporarily as in the conventional art, and the total time required for the brazing material adhesion is shortened.
The technical solution of the second aspect is based on the technical solution of the first aspect,
in the deceleration soaking step, the speed is linearly decelerated after the deceleration changing point is exceeded.
According to the above configuration, the deceleration speed of the nip portion can be easily controlled.
The third aspect is based on the first aspect,

According to the above configuration, the deceleration speed of the nip portion can be decelerated more smoothly.
A fourth aspect is the video display device according to any one of the first to third aspects,
in the back-off process, the acceleration is non-linearly accelerated.
According to the above configuration, even when the solder is gradually immersed in the solder bath and then retreated, the solder is gradually accelerated, and thereby uniform and perfect adhesion of the solder can be performed.
In the invention according to the fifth aspect, on the premise of an electric wire processing method in which the covering portion of the covered electric wire is removed and the brazing material is adhered to the end portion of the covered electric wire in which the core wire portion is exposed,
the wire processing method includes:
a holding step of clamping the exposed core wire portion of the coated electric wire and the coating portion in the vicinity of the core wire portion by a clamping portion;
an acceleration approach step of causing the clamp portion to approach a brazing material groove located in front of and below the clamp portion while accelerating;
a deceleration immersion step of immersing the flux groove after approaching while decelerating after the acceleration approach step,
and a retreating step of raising the clamping part upward after the deceleration immersion step, wherein
In the retreat step, the acceleration is slowly accelerated linearly or nonlinearly, and the retreat acceleration is increased at an acceleration change point arbitrarily set in the retreat process after being pulled out from the drill groove.
According to the above structure, the solder finish degree is improved, the time for reaching the constant speed can be shortened, and the solder can be attached more rapidly and efficiently.
The invention according to a sixth aspect is premised on a brazing material unit in which a brazing material is adhered to a core wire portion constituting a covered electric wire,
the disclosed device is provided with:

According to the above configuration, since the exposed core wire portion is brought close to the solder groove without stopping and gradually brought close to the solder, the opposite side of the core wire portion does not swing, and damage to the crimp terminal or the electric wire can be suppressed. Therefore, it is not necessary to stop the brazing material once and insert the brazing material again as in the conventional case, and the total time required for brazing material adhesion is shortened.
Seventh aspect on the basis of the technical solution of the sixth aspect,
the control unit is configured to linearly or non-linearly adjust the rotational speed after the deceleration changing point.
According to the above configuration, the exposed core wire portion can be brought close to the brazing material gradually by the control portion, and the brazing material can be attached to the core wire portion quickly and efficiently with good finish.

Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Structure of the wire handling device
As shown in fig. 4, the electric wire processing apparatus 1 according to the embodiment of the present invention includes: the device comprises a length measuring unit 2 of a front clamp 2a, a cutting unit 3, a rear clamp 4, a twisting unit 5, a flux unit 6, a brazing filler metal unit 7, a terminal pressure welding unit 8, and moving units 9 and 10 for moving the length measuring unit 2 and the rear clamp 4.
Next, a process flow of the coated electric wire 12 will be briefly described, in which the coated electric wire 12 is fed by a predetermined amount in the direction of the arrow P along the electric wire feeding line X by the length measuring means 2, and the coated electric wire 12 is gripped by the front gripper 2 a.
The coated electric wire 12 on the front clip 2a side is peeled off to expose the core wire portion 12a of the end portion after the end portion is cut by the cutter unit 3. Thereafter, the terminal is moved to the position of the terminal crimping unit 8, the terminal is crimped to the front end portion of the covered electric wire 12 by the terminal crimping unit 8, and thereafter, the front clip 2a is returned to the initial position.
Thereafter, the grip of the front clip 2a is released, and the covered electric wire 12 is fed while measuring the length, and is fed by a predetermined length. Thereafter, the covered 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 covered portions 12b at both ends of the cut covered electric wire 12 are peeled off. At this time, the covered portion 12b of the cut covered electric wire 12 held on the rear clip 4 side is in a so-called half-peeled state in which it is not detached from the core wire portion 12 a. Further, the covering portion 12b may be in a peeled state.
Then, the coated electric wire 12 on the rear clamp 4 side is moved to the position of the twisting unit 5 by the moving unit 10, the core wire portion 12a is twisted by the twisting unit 5, and the coated portion 12b is pulled out from the core wire portion 12 a.
Thereafter, the flux unit 6 is moved to the position, and the core wire portion 12a is dipped in the flux groove 6a of the flux unit 6.
Next, the coated electric wire 12 with the flux solution attached thereto is moved to the position of the brazing filler metal unit 7, the core wire portion 12a is immersed in the brazing filler metal groove 7a of the brazing filler metal unit 7, and the brazing filler metal 14 is attached to the core wire portion 12 a. The coated electric wire 12 with the brazing material 14 attached thereto is discharged to a predetermined electric wire discharge portion (not shown). Thereafter, as shown in fig. 4, the front clip 2a and the rear clip 4 return to the opposite initial positions.
By repeating the above operations, the covered electric wire 12 is sequentially manufactured, in which the terminal is crimped to one end portion thereof and the brazing material 14 is attached to the other end portion thereof.
Structure of the solder unit
Next, the brazing filler metal unit 7, which is a feature of the present invention, will be described in detail.
As shown in fig. 1 to 3, the brazing material unit 7 includes: the solder pot 7a, a device mount 71 that supports the solder pot 7a and forms a bottom portion, a support shaft 72 that is rotatably supported around a horizontal axis at an upper portion of the device mount 71, a servo motor 73 provided at an upper portion of the device mount 71, an interlocking mechanism 74 for driving the support shaft 72 forward and backward by forward and backward driving of the servo motor 73, and a pivot arm 75 that is connected to an upper end portion of the support shaft 72 so as to pivot integrally. The servomotor 73 and the link mechanism 74 constitute a rotation mechanism 77 for rotating the rotation arm 75. The turning mechanism 77 is precisely and reliably rotation-controlled by the control section 36.
The rotating arm 75 includes a clamp cylinder 76 mainly composed of a cylinder disposed so as to be vertical in the standby posture shown in fig. 2, and as shown in fig. 1, has a pair of clamp portions 76a that can be opened and closed at the upper end portion thereof, and the clamp portions 76a are opened and closed by the expansion and contraction operation of the clamp cylinder 76, and the coated electric wire 12 conveyed by the rear clamp 4 is held by releasing the opening and closing operation.
The interlocking mechanism 74 includes a driving portion 74a coupled to the rotary shaft 73a of the servo motor 73 so as to rotate integrally therewith, a link plate 74b coupled to the distal end of the driving portion 74a so as to be rotatable, and a driven portion 74d coupled to the link plate 74b via a coupling pin 74c so as to be rotatable integrally with the support shaft 72. Then, the drive portion 74a, the link plate 74b, and the driven portion 74d are sequentially driven by the drive of the servo motor 73, and the support shaft 72 is rotationally operated.
By the rotation of the support shaft 72, the rotation arm 75 is configured to be freely changeable in a rotation range between an insertion posture in which the rotation arm 75 is tilted to immerse the core wire portion 12a in the brazing material 14 as shown in fig. 1 and a standby posture in which the rotation arm 75 is rotated by about 90 degrees to stand up to make the covered electric wire 12 substantially horizontal as shown in fig. 2.
The control unit 36 controls the driving of the servo motor 73, controls the rotation driving amount, the rotation speed, the stop time, and the like of the servo motor 73 according to a program provided in advance in accordance with the input of operation data to the operation panel 37 for inputting various kinds of operation data, and is configured to change and adjust the rotation driving amount, the rotation speed, the stop time, and the like freely by changing the input of the operation data.
Wire handling method
Next, a 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 the gripping step of step S01, the clamp cylinder 76 is expanded or contracted, whereby the covering portion 12b near the core wire portion 12a exposed from the covered electric wire 12 joined to the rear clamp 4 is gripped by the gripping portion 76a, and gripped in the standby posture as shown in fig. 2.
Next, in the acceleration approach step of step S02, the drive control of the servo motor 73 by the control unit 36 rotates the rotating arm 75 to bring the grip portion 76a closer to the solder groove 7a located forward and downward while accelerating.
After the acceleration approach step, in the deceleration approach step of step S03, the grip portion 76a is moved toward the solder pot 7a while decelerating. In step S04, which is a deceleration changing point arbitrarily set in the middle of the deceleration dipping process, the clamping portion 76a is further decelerated to dip the exposed core wire portion 12a into the brazing material 14 in the brazing material groove 7 a. That is, if the deceleration changing point is exceeded, the deceleration is decreased, and the speed is linearly decreased. Therefore, the exposed core wire portion 12a can be brought closer to the brazing material 14 gradually.
Next, in step S05, the exposed core wire portion 12a is immersed in the solder groove 7a by a predetermined length, and then the clamp portion 76a is stopped.
After the stop, in the retreat step of step S06, the servo motor 73 is driven in the reverse direction to lift the clamping portion 76a (the rotating arm 75) upward, and the standby posture is returned so that the covered electric wire 12 with the solder attached to the tip end is horizontal.
Thereafter, the product wire is delivered from the clamping portion 76a to the discharge clip, and dropped onto a tray to be stored as a product wire (not shown).
In the present embodiment, when the exposed core wire portion 12a is brought close to the solder groove 7a, the solder 14 is gradually brought close without stopping, and therefore, the operation of the opposite end portion of the covered electric wire 12 can be reduced. Therefore, compared to the case where the terminal is temporarily stopped immediately after the immersion as in the related art, damage due to disturbance of the crimp terminal or the electric wire can be prevented, and the total time required for the solder adhesion can be shortened.
Therefore, according to the present embodiment, the total time required for solder adhesion can be shortened, and damage to the crimp terminal and the electric wire can be suppressed, so that the solder adhesion can be completed perfectly. Further, according to the present embodiment, the electric wire processing apparatus 1 capable of adhering the brazing material 14 to the end portion of the covered electric wire 12 in a short process is obtained.
(other embodiments)
The present invention may be configured as follows with respect to the above-described embodiment.
That is, in the above embodiment, as shown in fig. 6, in the deceleration approaching step, after the deceleration changing point is exceeded, the deceleration is linearly performed. Thus, the approach speed of the nip portion 76a can be easily controlled, but as shown in fig. 7, the deceleration may be performed non-linearly after the deceleration changing point is exceeded in the deceleration dipping step. This allows the speed of approach of the gripping portion 76a to be reduced more smoothly.
In the above embodiment, the rotational speed of the rotating arm 75 in the retracting step is linearly increased, but as shown in fig. 8, the rotational speed in the retracting step may be increased nonlinearly. In this way, the brazing material that is rapidly accelerated and semi-dried when the brazing material is not completely dried can be prevented from becoming unstable, and a more perfect finish of the brazing material can be obtained.
As shown in fig. 9, the acceleration approaching step and the deceleration immersing step may be linearly operated, and in the retreat step, the acceleration may be nonlinearly gradually accelerated until the flux groove 7a is extracted, and the acceleration may be increased at an arbitrary acceleration change point after the flux groove 7a is extracted. This increases the acceleration after the solder is gradually pulled out from the solder pot 7a, and therefore, the effects of improving the finish of the solder and shortening the solder processing time are obtained.
Further, as shown in fig. 10, the acceleration approaching step and the deceleration immersing step may be linearly operated, and in the retreat step, the acceleration may be linearly and gradually increased until the flux groove 7a is extracted, and the acceleration may be increased at an arbitrary acceleration change point after the flux groove 7a is extracted. This provides the same effect as the embodiment shown in fig. 9.
In the above embodiment, the terminal is crimped, and then the twist is applied, and then the solder is attached, but conversely, the twist may be applied to the front side, and then the solder is attached, and then the terminal is crimped to the rear side. The present invention can also be applied to the electric wire processing apparatus 1 in which the solder is attached to both the front side and the rear side.
