Abstract

PURPOSE:To perform solderless terminal processing operation effectively by stopping a piece of wire, which is taken out of a accommodating mechanism for wire cut in regular lengths, in a specified position, supplying to a solderless terminal processing machine with the foremost part gripped and thereby accomplishing automatic and quick feeding of different types of wire to various terminals. CONSTITUTION:If a thrust force is applied by a connecting rod 308, links 303, 306 rotate forward to take vertical attitude, when a vertical member 305 will come in contact with a stopper plate 314 to cause restraint of rotation. To a V-shaped cutting edge 310 the undermost piece of wire 9a accommodated in an accommodating mechanism 2 is pinched inside and lifted up so that the cutting edge 310 is bitten into the covering. Thereby the heaving force applied to the undermost wire 9a is also transmitted to other pieces of wire 9 to turn into a vibratory motive to cause the pieces of wire to fall into alignment one after another when each piece 9a has slipped off. If further thrust force is applied, a slide table 302 slides on a fixed table 301, and the cutting edge 310 slips off from the wire 9a simultaneously. The wire 9a taken out by a takeout mechanism 2 is stopped in specified position, and after location by a locating mechanism 4, the wire is fed to a solderless terminal processing machine 5 automatically by a feeding mechanism 6. This arrangement ensures an enhanced efficiency in operation.

Inside the base 1, an air actuator for operating each of the above-mentioned mechanisms, a control section thereof, and the like are housed.

As shown in FIGS. 1 to 3 and 7, the wire accommodation mechanism 2 is formed in the shape of a triangular groove widened to approximately 90 degrees, and the side plate 201 in the distal direction has a vertical groove in the center. A cut 202 is formed, and @W of this cut 202 is the electric wire 9
The diameter d is preferably about 1.2 to 1.3. Rotate the adjustment screw 203 according to the electric wire 9 to be used to adjust the side plate 2.
Adjustment plate 204 slidably attached to 01 is inserted into the cut 2
Adjust by moving # in the direction perpendicular to 02.

Further, the upper edge 205 of the side plate 201 has the cut 2
The angle tL/ of the hip inclined toward the center in the 02 direction is increased or varied in this embodiment, but it can be determined as appropriate depending on the electric wire, but this upper end R205! Tip 9 of electric wire 9
01 is mounted and the rear part is placed in the groove 206, the tip 901 of the electric wire 9 may slide on the upper ylA edge 205 and be inserted into the cut 202. Furthermore, both side plates 201 and 2 are positioned across the cut 202.
01 is formed to be longer by a length t at the upper end of the cut 202, and the length t is at least the diameter d of the wire 9.
Therefore, both precious plates 201.2
When a large number of electric wires 9 are placed on the upper edge 205. In this state, they are stacked vertically in a line within the cut 202 and aligned head by head. In addition, in this embodiment, the triangular groove portion is formed by two groove members 207 and 208.
The groove member 208 on the rear end side is composed of the groove member 2 on the front end side.
It is possible to adjust the length by moving the electric wire 07, and the length can be adjusted as appropriate depending on the length of the electric wire used. A takeout mechanism 3 is provided below the cut 202 of the storage mechanism 2 to sequentially take out a single wire from a large number of wires 9 stored in the storage mechanism 2. This take-out mechanism 3 has a sliding base 302 that can be slid in the longitudinal direction on a fixed base 301 fixed to the base 1 (see @ Figures 1 and 2) shown in Figures 3 and 4.
The link member 30 is fitted onto the slide table 302.
The lower part of 3 is attached to the shaft.

The upper part of this link member 303 is connected to a horizontal member 304, and this horizontal member 3041 is fixed via a vertical member 305') link member 306 whose upper part protrudes. A connecting rod 308 to the air actuator 10 is connected to the rear surface 307, and a blade member 311 having a V-shaped blade 310 with an open upper end is attached to the front surface 309 with a screw 312 with the blade 310 positioned upward. (see No. 71).

Note that this blade member 311 is operated when the connecting rod 308 moves forward and the link members 303 and 306 are in the vertical position (the fifth
(state shown in the figure), the blade 310 is attached so as to sandwich and grasp the lowest electric wire 9a of the electric wires aligned and housed in the cut 202 of the storage mechanism 2, and the shaft of the link member 303 The friction coefficient for the attachment part is based on the fixed base 3.
01 and the sliding table 302 is set to be smaller than the friction coefficient. To explain the operating state of the take-out mechanism 3 having such a configuration, first, as shown in FIG. When the vertical member 305 rotates forward about 312 and rises to a vertical position, the front surface 309 of the vertical member 305 comes into contact with a stop plate 314 that is vertically installed on the sliding table 302#.

Its rotation is restricted, resulting in the state shown in FIG. At this time, the V-shaped blade 310 pinches the lowest electric wire 9a housed in the housing mechanism 2 inside and pushes it upward.Since the electric wire 9 is generally covered with a soft synthetic resin material, the covering part number The blade 310 bites in and the two form a fitted state (see FIG. 7). At the same time, the pushing up force applied to the lowest electric wire 9a is applied to the other electric wire 9a stacked on top of this electric wire 9a.
2cifii! It was also communicated to 9.

When the lowest electric wires 9& are pulled out, they easily fall into the cut 202 one after another and act as a vibrating force to align them.

The opening angle of the V-shaped blade 310 may be any angle that allows the electric wire 9a to be caught in the cage at the tip, but it is preferably about 4 degrees. When a thrust force is applied to the member 305, the vertical member 305 is in contact with the stop member 314, so the thrust force is applied to the slide table 302.
, the sliding table 302 slides forward on the fixed table 301, and at the same time the V-shaped blade 310 pulls out the lowest electric wire 9 & forward (see Fig. 6). The extracted electric wire 9a is connected to the supply mechanism 6 (Figs. 1 and 2).
When the connecting rod 308 is held by the vertical member 305 (see figure), the connecting rod 308 pulls the vertical member 305 back. Since the friction coefficient is set smaller than the friction coefficient, link members 303 and 306 are first
rotates rearward about the shaft 312 in the opposite direction to the above. At this time, since the V-shaped blade 310 first moves downward, the fitting with the extracted lowest electric wire 9a is released. Then, when the connecting rod 308 is further pulled back, the vertical member 305 is pulled back, and the sliding base 302 is moved back to the fixed base 30.
1 to the original position and return to the state shown in Figure 4.

A positioning mechanism 4 is provided in front of the take-out machine ffl 3 to stop the taken-out electric wire 9a at a predetermined position. This positioning mechanism 4 is shown in FIGS.
As shown in FIG. 9, a positioning mechanism main body 403 is rotatably mounted on a side plate 402 vertically mounted on a fixed base 401 fixed to the base 1 through a shaft 404I so as to be rotatable in the front and back direction. A conical hole 40 is provided in the upper part of the main body 403.
5 is formed. and.

When stopping the electric wire 9& taken out by the extraction mechanism 2 at a predetermined position, the tip end 9b of the electric wire 9a is inserted into the hole 405.
(the state shown by the electric wire in FIG. 2), and after being held by the supply mechanism 6, the shaft 4
04 (shape u shown by the chain line in FIG. 2), this positioning mechanism presses and inserts the tip 1fls9b of the electric wire 9a into a conical hole 405 as shown in FIG. The electric wire 9a is taken out with a constant force, and as shown in FIG. Then, the tip end 9b bites into the hole wall 406 and stops. At this time, the hole fi 406 is
The force F for gripping the tip 9b is given by F '' f coi (f is the entry force, e is the opening angle of the hole 404).

Therefore, if O is almost Go, it will be grasped with about 3.7 times the force of the entry force, and will not bounce back.

In addition, if a certain electric wire enters with a certain advancing force, it can be stopped at a certain position with extremely high precision. If so, it can be used with electric wires of various diameters and materials, and of course can be used even if the coating is removed from the tip. Note that in this embodiment, the electric wire 9& is connected to the supply mechanism 6.
After the holding part 601 holds the positioning mechanism main body 403
Although the electric wire 9a is rotated in the front direction about the axis 404 to disengage the electric wire 9a from the hole wall 406 of the hole 405, it is held by the holding part 601 of the supply mechanism 6 and pulled out as it is, or the positioning mechanism Other configurations may also be used, such as a configuration in which the main body 403 is divided in advance along the axis.

The electric wire 9a stopped at a predetermined position by the positioning mechanism 41 is shown in FIGS. 1, 2, and 1.
The wire is supplied to the terminal crimping machine 5 by a supply mechanism 6 shown in FIG.
A wire stripper mechanism 7 is provided to use the electric wire 9 cut to size without the 59bO coating removed. In the supply mechanism 6, an arm 603 rotates forward and to one side about a shaft 602 attached to the base 1, and holds the tip of the electric wire 9a stopped at a predetermined position by the take-out mechanism 3 and the positioning mechanism 4. In this embodiment, the wire 9a is held at the holding part 601 and the coating from the tip 9b of the electric wire 9a is stripped off by the wire stripper mechanism 7. However, in this embodiment, the wire slipper mechanism 7 has a box shape as a whole, as shown in FIG. TS1 and FIG. Members 702, 702 are provided, and the tips 703, 7031 of these rod members 702, 702 on the side of the positioning mechanism 4 are provided with blades 704, 70 in the center.
4 are each formed. Then, as shown in FIG. 10, the rod members 702, 702 move in the direction of the electric wire 9a in an expanded state, and as shown in FIG.
4.704 stops at a predetermined position.

The rod member 702.7 is attached to the parallel expanded grid 701.
When 02 moves in the closing direction, Fig. 13 and Fig. 13 (
As shown in b), the blade 704.704 penetrates the covering portion of the electric wire 9a, and in this state, the rod member 702.7
02 is moved parallel to the direction opposite to the electric wire 9a, and the covering portion is stripped off by a predetermined length. 9 In this embodiment, the blades 704, 704 are each V-shaped as shown in FIG. 13, and the cross section thereof has an inclination b that closes toward the stripping direction, that is, toward the tip fi9b. These blades 704 are constructed so as to be suitable especially when a soft vinyl or the like is used as the covering material, but they are constructed in accordance with the covering material of the electric firing 9a. Further, the holding portion 601 of the supply mechanism 6 has a fixing jaw 604 protruding from its upper surface, and the arm 603 from its lower surface.
It is composed of a plate-shaped holding member main body 605 to which the distal end is fixed, and a movable shaft 606 facing the fixed shaft 604. The rear end 6 of the link mechanism 609 is connected to the link mechanism 609.
The fixed jaw 60 is fixed by the longitudinal thrust applied to 10.
4 and is configured to form an open/closed state.

Furthermore, 8 is a scraping mechanism for scraping out the electric wire 9 with a terminal crimped by the terminal crimping machine 5 from the terminal crimping machine 5;
As shown in FIG. 1, a downward claw 802 attached to the tip of a rotary arm 801 grips an electric wire (not shown), rotates the rotary arm 801, takes out the wire from the terminal crimping machine 5, and uses a pick-up to remove the wire from the terminal crimping machine 5. 802 is opened and scraped out.

In order to use the wire feeder for the terminal crimping machine having such a configuration, first, the wires 9 that have been straight-stretched and cut to size are bundled as shown in FIG. Arrange them and store them in the storage mechanism 2. At this time, with the tip 901 of the electric wire 9 protruding forward from the upper edge 205 of the side plate 201, the upper edge 2051 is 4I! The base portion (not shown) is housed within the groove member 208 . At this time, the length of the housing member 2 is adjusted by sliding the groove member 208 against the groove member 207 according to the length of the electric wire 9 to be used, and by adjusting the adjusting screw 203 according to the diameter of the electric wire 9 to be used. Cut 2
Adjust the width W of 02 (see Figure 8). Then, when the wire feeder is operated, the take-out mechanism 3 causes the storage mechanism 2 to
A single electric wire 9a out of the electric wires 9 housed in the wire is taken out (see WiJ figures to FIGS. and stop. At this time, if the degree of expansion 405 formed on the positioning mechanism strip main body 403 is too large for the diameter of the electric wire 9, it will bounce back, and if it is too small, the gripping force will be great and it will be difficult to remove. Since there are some obstacles, select an appropriate one in advance and use it.

Further, when the electric wire 9a is inserted into the positioning mechanism 4, the supply mechanism 6 waits with the arm 603 facing the same direction as the longitudinal direction of the electric wire 9a (see FIG. 14). is a fixed jaw 604 and a movable jaw 606 in an open state.
It will be inserted between. Next, the movable jaw 606 is moved in the closing direction, and the tip 901 of the electric wire 9a is gripped by the nine jaws 604 and 606. At this time, [Ii! i! Since the holder 9a is always stopped at a fixed position by the positioning mechanism 2, the holding part 601 can always grip the same part from the tip 9b. When the holding part 601 grips the tip 901 of the electric wire, the positioning mechanism main body 403 of the positioning mechanism 2 rotates forward about the shaft 404 and releases the engagement with *tm9a (as indicated by the chain line in FIG. 2). state).

Then, the wire stripper mechanism 7
The coating on the tip 9b of the gripped electric wire 9a is peeled off (see FIGS. 10 to 12).

When the stripping work of the affected part is completed, the supply mechanism 6 rotates the arm 603 in one direction about the shaft 602, and the tip part 9b of the gripped electric wire 9a is attached to the terminal crimping JIA5. Insert into the wire insertion part (not shown). Then, the supply mechanism 6 again moves the moving jaw 606 in the opening direction and rotates the I-arm to return to the original state. On the other hand, the electric wire 9a with the terminal crimped thereon is automatically discharged depending on the configuration of the terminal crimping machine i.
If this needs to be scraped out as it is or by fitting it into a die, it can be scraped out using the scraping mechanism 8.

In addition, if the ``m wire 9a'' is short, when its tip 90 is taken out from the accommodation mechanism 2 by the extraction mechanism 3, it has already been detached from the accommodation mechanism 2, and the other wires 9 are at the lowest position of the cut 202. Sequentially.

However, if the wires m9a are much longer than the arm 603 of the supply mechanism 60 (see Figure 1), the scraping operation will cause the wires 9& to come out of the storage mechanism 2 for the first time, and the scraping mechanism 8 It becomes necessary.

Then, when the above-mentioned -stroke is completed, each mechanism returns to its initial state again and repeats the operation in sequence. These operations are performed by an air actuator housed inside the base 1 and a control mechanism that controls them (illustration light).
