  Further, although not shown in the figure, there are provided static elimination air ejection means (static generation prevention means) for blowing static elimination air to prevent static electricity from being generated on the fine wire T in the induction valley portion 11.

  In the present invention, the ultrafine wire T is, for example, a conductive needle (probe pin) used for inspection of a semiconductor circuit or the like. There are cases where the tip has an end surface orthogonal to the axis (not needle-like) and a needle-like shape having a tip that is tapered in a tapered shape. The material is made of metal such as tungsten. Further, “extra fine” means that the diameter d is 0.05 mm to 0.5 mm. The extra fine wire T is formed in a short dimension having a length of 20 mm to 100 mm.

Next, the usage method (action) and the ultrafine wire material extraction method of the ultrafine wire material extraction device of the present invention will be described.
First, the longitudinal axis La of the guide trough 11 is set to a predetermined tilt angle θ1 suitable for the size and length of the extra fine wire T, for example, 65 degrees by the tilt adjusting means 7.

  A plurality of ultrafine wires T are stood against the induction valley 11 and accommodated. In FIG. 6, the extra fine wire T disposed near the innermost corner 11e tends to approach the innermost corner 11e by the load of the other extra fine wire T, but in the vicinity of the innermost corner 11e. In some cases, an arch structure is formed between the ultrafine wires T and a bridge phenomenon occurs, and the ultrafine wires T may not be arranged in the innermost corner 11e. As shown in FIG. The extra fine wire T is not disposed on the outer side, and the extra fine wire T does not protrude from the extraction hole 21.

  Therefore, when vibration is applied to the holding member 1 by the vibration means 3, the bridge is broken, and as shown in FIG. 3, the ultrafine wire T is guided in the direction of the innermost corner 11 e, and one ultrafine wire T is the most As shown in FIG. 4, only one ultrafine wire T protrudes from the extraction hole 21 as it enters the back corner 11e.

  The vibrator 39 is stopped by confirming with the sensor that the ultrafine wire T protrudes one by one from the plurality of guide troughs 11 of the holding member 1 shown in FIG. 2 and contacts the stopper 51. To do. With the holding member 1 (induction valley portion 11) in an inclined state (without moving the tilting base member 72), a group of the ultrafine wires T arranged in parallel one by one and in an inclined state are extracted. 2 and is pulled downward along the longitudinal direction Na from the guide trough 11. The gripping means 5 holding the ultrathin wire rod T group in the parallel and parallel state is detached from the linearly reciprocating means 6 and sent to the next step. Thereafter, the new gripping means 5 or the gripping means 5 after completion of delivery of the extra fine wire T in the next step is attached to the rectilinear reciprocating means 6.

  Then, by applying vibration to the holding member 1 again, the extra fine wire T is disposed in the innermost corner 11e, and one extra fine wire T protrudes from the extraction hole 21. And if a protrusion is confirmed, a vibration will stop. In the extraction means 2, only one ultrafine wire T is taken out from each induction trough 11 and sent to the next process. This extraction operation is repeated.

  Here, even if the ultrafine wire rod T at the innermost corner 11e is taken out while the induction valley portion 11 is in the inclined state, the following ultrafine wire rod is caused by the bridging phenomenon, the frictional force between the holding member 1 and the partition member 20, or the like. T does not move to the innermost corner 11e and does not protrude from the extraction hole 21. Moreover, even when the remaining number of the accommodated extra fine wires T is reduced to 2-3, the extra fine wires T do not move to the innermost corner 11e due to frictional force or the like until vibration is applied. It does not protrude from the extraction hole 21.

In other words, in the non-vibration imparting state, the induction valley portion 11 has an inclination angle θ1 of the induction valley portion 11 of 50 degrees or more and less than 90 degrees so that the ultrathin wire material T is not disposed in the innermost corner portion 11e. , 60 degrees or more and 70 degrees or less. Further, the inclination angle θ2 of the partition member 20 is set so as to exceed 0 degree and not more than 40 degrees, and preferably not less than 20 degrees and not more than 30 degrees. Further, the opening angle α of the induction valley portion 11 is set to 60 degrees or more and 120 degrees or less, preferably 80 degrees or more and 100 degrees or less. More preferably, the tilt angle θ1 is approximately 65 degrees, the tilt angle θ2 is approximately 25 degrees, and the opening angle α is approximately 90 degrees.
If it is out of the above-mentioned range, there is a possibility that the next extra fine wire T moves to the innermost corner 11e and protrudes even when the bridge phenomenon does not occur or the frictional force is small and it is not vibrated. Further, even if it is vibrated, there is a possibility that it will not move to the innermost corner 11e and clogging may occur, or a long vibration generation time will be required until it moves, and work efficiency may deteriorate.

  In the present invention, the design can be changed, and in FIG. 2, the partition members 20 are provided one by one so as to correspond to the respective induction valley portions 11 and can be individually positioned. A strip plate may be provided, and one of the strips may be provided with an extraction hole 21 corresponding to each induction valley portion 11. In some cases, the upper flat surface 20a of the partition member 20 and the tip lower end surface 1a of the holding member 1 may be provided in close contact with each other.

  As described above, the ultrafine wire rod take-out device of the present invention includes a holding member 1 having a guide valley portion 11 having a V-shaped cross section for accommodating a plurality of fixed-size ultrafine wire rods T in an inclined manner, and an induction valley An extraction hole 21 opened corresponding to the lower end in the longitudinal direction Na of the innermost corner 11e of the portion 11, and a vibration for intermittently applying to the holding member 1 vibration for projecting one ultrafine wire T from the extraction hole 21 Therefore, it is possible to reliably and smoothly take out the ultrafine wires T one by one from the plurality of ultrafine wires T, thereby shortening the working time. Regardless of the number of ultrafine wires T that are accommodated, the time required for removal can be stabilized and work efficiency can be improved.

  In addition, since the tilt angle θ formed by the longitudinal axis La of the induction valley portion 11 with respect to the horizontal plane S is set to 50 degrees or more and less than 90 degrees, the induction vibration generation state is reliably and smoothly removed from the fine wire T. In addition to being able to send to 21, in the vibration generation standby state, the extra fine wire T is not reliably protruded from the extraction hole 21, and the extraction operation can be made more stable.

  Further, since the inner diameter dimension D of the extraction hole 21 is set to be more than 1 time and less than twice the diameter dimension d of the ultrafine wire material T, the next ultrafine wire material T (waiting for the induction vibration generation) Can be taken out one by one without sliding down. Even if the ultrafine wire T is slightly bent, it can be reliably projected from the take-out hole 21.

  Also, the holding means 1, the vibrating means 3, the drawing means 2, etc. are inclined because the holding means 1, the vibrating means 3, the drawing means 2, etc. Therefore, it is not necessary to perform a large tilting operation so as to lie down horizontally, so that the take-out operation can be performed easily and quickly. Since the take-out operation is performed while the tilt angle θ1 is kept constant, the operation is stabilized.

  In addition, the method of taking out the ultrafine wire rod according to the present invention includes accommodating a plurality of fixed-size ultrafine wire rods T in an inclined manner on the guide valley portion 11 having a V-shaped cross section, and Since vibration for projecting the ultrafine wire T is intermittently applied from the take-out hole 21 opened corresponding to the lower end of the longitudinal direction Na of the portion 11e, the ultrafine wires T are taken out one by one, so a plurality of ultrafine wires One piece can be reliably and smoothly removed from T, and the working time can be shortened. Regardless of the number of ultrafine wires T that are accommodated, the time required for removal can be stabilized and work efficiency can be improved.
