The present invention also aims to provide a positioning device with improved quality.

To this end, the present invention includes a base plate, a pedestal that is slidably moved along a guide groove of the base plate, and a first pedestal that is disposed on the pedestal and that is in contact with one side edge of the member to be positioned. a guide, a pressing member disposed along the first guide for pressing the positioned member onto the pedestal; and a pressing member disposed along the first guide and pressing the positioning member onto the pedestal by the pressing member; a second guide for positioning one end of the member to be positioned held by the member; and an evacuation means for retracting the second guide from the sliding path of the pedestal prior to sliding movement of the pedestal. The present invention provides a positioning device comprising:

The present invention also provides a positioning device in which a retracting means includes a solenoid fixed to a base plate and a link inserted between the solenoid and a second guide.

After rotating around the cable guide 25 to position and arrange the flat cable 26, it rotates around the hinge 28 again to hold down the flat cable 26. As a result, an appropriate force is applied to the flat cable 26 by the coil spring 29, thereby preventing its displacement. 30 is the second guide or cable stopper of the positioning device of the present invention;
When the cable holder 24 is in the retracted position, that is, when it is furthest away from the contact terminal metal feed rail 1, it is located at the front end of the cable holder 24, and the front end of the flat cable 26 is positioned. A position detection plate 31 is protruded from one side of the cable cradle 24, and when the cable pedestal 24 is in the retracted position, the detector 32 is activated and in the forward position, that is, the cable pedestal 24 is in the contact terminal metal feed rail. 1, the detector 33 is activated.

A spring 37 causes the cable stopper 30 to return to its original position.

Reference numeral 51 denotes an upper pressure welding punch, which is moved by an electric press 52 toward the contact terminal metal band 2 disposed in the guide groove 3 of the contact terminal metal feed rail 1 and placed on the lower pressure welding punch 53. A plurality of protrusions are formed on the pressure contact surface of the upper pressure contact punch 51 for pressure contacting each contact terminal fitting to the front end of the flat cable 26, and a plurality of protrusions are formed on the pressure contact surface of the lower pressure contact punch 53. A plurality of other protrusions are formed that cooperate with the protrusions on the pressure contact surface to press the contact terminal fitting to the front end of the flat cable 26. A lower pressure welding punch 5 is provided near the rear edge of the pressure contact surface of the upper pressure welding punch 51 together with the upper pressure welding punch 51.
A positioning pin 51a that is moved toward 3 is provided. A movable part 54 is formed in a part of the lower press-contact punch 53, and is moved relative to the remaining part while resisting the buffer spring 55 when the upper press-contact punch 51 is press-contacted. A portion of the contact terminal metal feed rail 1 is removed near the front edge of the lower pressure welding punch 53, that is, the portion facing the cable holder 24, and a recess 5 is formed.
It is said to be 6. Rear end 5 of lower pressure welding punch 53
7 is at the same height as the bottom surface of the guide groove 3 of the contact terminal metal feed rail 1, and guides the base of the contact terminal metal band 2. A guide member 58 is disposed at the rear end 57 of the lower pressure welding punch 53 at a slight distance from the surface thereof and guides the positioning pin 51a and fixes the base, that is, the edge portion of the contact terminal metal band 2 during pressure welding. . That is, by advancing the cable holder 24 toward the front edge of the lower pressure welding punch 53, the front end of the flat cable 26 is pushed into each terminal of the contact terminal fitting band 2 on the lower pressure welding punch 53, and then the upper pressure welding punch 51 is moved forward. Then, the positioning pin 51a is moved toward the lower press punch 53 by the electric press 52. The positioning pin 51a is inserted into the guide hole 5 at the base of the contact terminal fitting band 2 via the guide hole 59 of the guide member 58. Since the movable part 54 of the lower pressure welding punch 53 moves toward the base plate 21 due to the pressure welding of the upper pressure welding punch 51, the rear edge of the rear half of the pressure contact surface of the upper pressure welding punch 51 and the rear end portion 57 of the lower pressure welding punch 53 are then moved. The leading edge cuts and separates the connecting portion between the base of the contact terminal fitting band 2 and each contact terminal fitting. Further, the movable parts 54 of the upper pressure welding punch 51 and the lower pressure welding punch 53 move toward the base plate 21, so that each contact terminal A metal fitting is pressed against the front end of the flat cable 26. Reference numeral 60 denotes a push plate that prevents the contact terminal metal band 2 from floating up from the contact terminal metal feed rail 1 in the vicinity of the lower pressure welding punch 53.

Furthermore, the operation of the positioning device of the present invention will be explained in detail.

First, the contact terminal metal band 2 is pulled out from the supply source and placed in the guide groove 3 of the contact terminal metal feed rail 1 via the guide roller 16, and the guide hole 5 at the base of the contact terminal metal band 2 is inserted into the conveying sprocket 4. engage. After rotating the mounting bar 11 to place the push roller 10 on the contact terminal fitting band 2, a foot switch (not shown) is pressed to drive the step motor 6. The step motor 6 is operated intermittently depending on the number of times the foot switch is pressed, and the conveying sprocket 4 is rotated intermittently. As a result, the contact terminal fitting band 2 is intermittently moved toward the lower pressure welding punch 53. When the contact terminal fitting band 2 reaches a predetermined position on the lower pressure welding punch 53, the pressing of the foot switch is finished.

Next, the cable pushing member 27 is attached to the coil spring 29.
The flat cable 26, which is the member to be positioned, is placed on the cable holder 24. The flat cable 26 is positioned by abutting one side edge against the cable guide 25 and abutting the front end against the cable stopper 30. The cable pushing member 27 is closed and the flat cable 26 is pressed and held by the spring force of the coil spring 29. Thereafter, pressing another foot switch (not shown) energizes the solenoid 34 and lowers the cable stopper 30. After the cable stopper 30 is lowered, the lever 23 is held and the cable holder 24 is moved forward toward the lower pressure welding punch 53. The front end of the flat cable 26 is pushed into each contact terminal fitting of the contact terminal fitting band 2 on the lower pressure welding punch 53. When this state is detected by the detectors 32 and 33, the electric press 52 is driven and the upper press punch 51 is moved toward the lower press punch 53. The positioning pin 51a is inserted into the guide hole 59 of the guide member 58 and then into the guide hole 5 at the base of the contact terminal fitting band 2. Next, the movable part 54 of the lower pressure welding punch 53 moves toward the base plate 21 due to the pressure of the upper pressure welding punch 51.
The connecting portion between the base of the contact terminal metal band 2 and each contact terminal metal fitting is cut and separated by the rear edge of the rear half of the pressure contact surface and the front edge of the rear end portion 57 of the lower pressure contact punch 53. Since the movable parts 54 of the upper pressure welding punch 51 and the lower pressure welding punch 53 continue to move toward the base plate 21, each contact occurs between the front half of the upper pressure welding punch 51 and the front half of the lower pressure welding punch 53, that is, the non-movable part. A terminal fitting is pressed into contact with the front end of the flat cable 26. At this time, contact terminal metal band 2
Since the pitch between each contact terminal fitting is normally 5.08 mm and the pitch between each conductor of the flat cable 26 is 2.54 mm, the contact terminal fittings are pressure-welded to the conductors of the flat cable at intervals. When the pressing operation is finished, the upper pressing punch 51 and the lower pressing punch 53 return to their original positions.

The cable holder 24 is moved backward by the lever 23. When the cable holder 24 is in the retracted position, the step motor 6 is automatically driven and rotated by a predetermined pitch while being counted by the detector 9. As a result, the contact terminal metal band 2 is placed on the lower pressure welding punch 53 at a position displaced by half a pitch, that is, 2.54 mm, from the position at the previous pressure welding. Thereafter, the cable pedestal 24 is moved forward again toward the lower pressure welding punch 53, and the same pressure welding operation as the previous time is repeated.

After the pressure welding operation is completed, grasp the lever 23 to move the cable holder 24 backward, and then move the cable pushing member 2
7 to open it and remove the flat cable 26 from the cable holder 24.

By pressing the other foot switch to raise the cable stopper 30 and repeating the above operation, the contact terminal fitting can be pressed into contact with a new flat cable.

Although the above description assumes that the number of conductors in the flat cable is constant, the present invention can also be applied to process flat cables with different numbers of conductors. That is, at least the cable holder may be made movable along the contact terminal fitting feed rail according to the number of conductors of the flat cable. This will be explained in more detail with reference to FIG.

A solenoid (not shown) is attached to the bottom surface of 1A, and when the cable holder 24A is moved forward, it is energized by pressing a foot switch (not shown) and rotates around a fulcrum (not shown). By attracting one end of the moved link (not shown) against a return spring (not shown), the cable stopper 30A is dropped, and the detector 33A detects the presence of the position detector 31A. It is kept in the energized state until the detector 32A detects the presence of the position detection plate 31A, and after removing the flat cable 26, it is de-energized by pressing the foot switch (not shown) again. By releasing one end of the link, the return spring causes the cable stopper 30A to return to its original position.

For other configurations, those explained in FIGS. 1 to 6 may be adopted.

In addition, the operation of the embodiment shown in FIG. 7 will be described in detail.

After rotating the mounting bar 11 to place the push roller 10 on the contact terminal fitting band 2, a foot switch (not shown) is pressed to drive the step motor 6. The step motor 6 is operated intermittently depending on the number of times the foot switch is pressed, and the conveying sprocket 4 is rotated intermittently. As a result, the contact terminal fitting band 2 is intermittently moved toward the lower pressure welding punch 53. When the contact terminal fitting band 2 reaches a predetermined position on the lower pressure welding punch 53, the pressing of the foot switch is finished.

Next, the cable holder 2 of the cable guide 25A is adjusted according to the width of the flat cable 26 that is the member to be positioned.

The front end of the flat cable 26 is pushed into the pressure contact portion of each contact terminal fitting of the contact terminal metal band 2 on the lower pressure contact punch 53. When this state is detected by the detectors 32A and 33A, the electric press 52 is driven and the upper press punch 51 is moved toward the lower press punch 53. The positioning pin 51a is inserted into the guide hole 59 of the guide member 58 and then into the guide hole 5 at the base of the contact terminal fitting band 2. Next, the movable part 54 of the lower pressure welding punch 53 moves toward the base plates 21A, 71 due to the pressure welding of the upper pressure welding punch 51, so that the rear edge of the rear half of the pressure contact surface of the upper pressure welding punch 51 and the rear end of the lower pressure welding punch 53 The front edge of the portion 57 cuts and separates the connecting portion between the base of the contact terminal fitting band 2 and each contact terminal fitting.

When the pressing operation is finished, the upper pressing punch 51 and the lower pressing punch 53 return to their original positions.

The cable holder 24A is moved back by the air cylinder 23B and the rod 23A. When the cable holder 24A is in the retracted position, the step motor 6 is automatically driven and rotated by a predetermined pitch while being counted by the detector 9. As a result, the contact terminal metal band 2 is placed in the same position on the lower pressure welding punch 53 as compared to the previous pressure welding position. On the other hand, cable cradle 2
4A is automatically moved to the right by a half pitch, that is, 2.54 mm, along the contact terminal metal feed rail 1 by the action of the air cylinder 75 and the rod 74. Thereafter, the cable holder 24A is moved forward again toward the lower pressure welding punch 53, and the same pressure welding operation as the previous time is repeated.

The cable pushing member 27E is closed and each core cable 26F is pressed and held by the spring force of the coil spring, and the cable pushing member 27F is closed and the base of the multi-core round cable 26E is pressed and held by the spring force of the coil spring 29E. . Thereafter, by pressing another foot switch (not shown), solenoid 34E is energized and cable stopper 30E is lowered. After the cable stopper 30E is lowered, the lever 23E is grasped and the cable holder 24E is moved forward toward the lower pressure welding punch 53. The front end of each core cable 26F of the multi-core round cable 26E is connected to the lower pressure welding punch 5.
3 is pushed into each contact terminal fitting of the contact terminal fitting band 2 on top of the contact terminal fitting band 2. When this state is detected by the detectors 32E and 33E, the electric press 52 is driven and the upper press punch 51 is moved toward the lower press punch 53. The positioning pin 51a is inserted into the guide hole 59 of the guide member 58 and then into the guide hole 5 at the base of the contact terminal fitting band 2. Next, upper pressure welding punch 5
1, the movable part 54 of the lower pressure welding punch 53
moves toward the base plate 21E, so
The rear edge of the rear half of the pressure welding surface of the upper pressure welding punch 51 and the front edge of the rear end 57 of the lower pressure welding punch 53 cut and separate the communication portion between the base of the contact terminal metal fitting band 2 and each contact terminal metal fitting. Ru. Since the movable parts 54 of the upper pressure welding punch 51 and the lower pressure welding punch 53 continue to move toward the base plate 21E, each contact occurs between the front half of the upper pressure welding punch 51 and the front half of the lower pressure welding punch 53, that is, the non-movable part. Each core cable 26F of multi-core round cable 26E with terminal fittings
is pressed against the front end of the When the pressing operation is finished, the upper pressing punch 51 and the lower pressing punch 53 return to their original positions.

The cable holder 24E is moved backward by the lever 23E. When the cable holder 24E is in the retracted position, the step motor 6 is automatically driven and the detector 9 is
It is rotated by a predetermined pitch while counting. As a result, the contact terminal metal band 2 is attached to the lower pressure welding punch 53.
The upper part is placed in the position at the previous pressure welding. Thereafter, the cable holder 24E is moved forward again toward the lower pressure welding punch 53 to prepare for the same pressure welding operation as the previous time.

After the pressure welding operation is completed, the cable holder 24E is moved backward by grasping the lever 23E, and then the cable pushing members 27E and 27F are lifted and released to remove the multicore round cable 26E from the cable holder 24E.

By pressing the other foot switch to raise the cable stopper 30E and repeating the above operation, the contact terminal fitting can be pressed into contact with a new multicore round cable.

It will be obvious that the cable stopper may be moved in response to a detector for detecting movement of the cable cradle or in response to movement of the cable cradle.

(3) Effects of the invention As is clear from the above, the present invention positions the member to be positioned in two directions orthogonal to each other using the first guide and the second guide, and also allows the second guide to be retracted. Since the member to be positioned can be moved in one direction, it has the effect of speeding up and simplifying the positioning work of the member to be positioned, as well as increasing precision. This has the effect of speeding up subsequent processing.
