As shown in FIG. 2, the storage bag 1 includes a bag-like bag body 1 a having an opening formed at one end thereof, and as described above, the static elimination brush unit 2 is provided along the periphery 15 of the opening. Yes.

  The bag 1a has flexibility and conductivity. That is, the bag body 1a has flexibility for protecting and storing electrical equipment and is formed using a conductive material in order to prevent electrostatic charging. As the bag 1a, for example, a surface of a synthetic resin bag body coated with a conductive thin film such as metal or carbon, a material coated with a conductive material, or a material kneaded with a conductive material in a synthetic resin Etc. are known.

  The static elimination brush part 2 is the tape-like (or strip | belt-shaped) and electroconductive support part 3 affixed on the bag body 1a along the opening periphery 15, and is supported by this support part 3, and follows a substantially opening direction. And a plurality of static elimination hairs 5 (static elimination hair group) arranged in the circumferential direction of the opening. That is, the neutralizing hair 5 is supported at one end by the support portion 3 and attached to the peripheral edge 15 of the opening of the bag body 1a, and extends from the inner side to the outer side of the bag body 1a in the substantially opening direction of the opening. The brush is arranged in the circumferential direction of the opening. The distal end portion of the static elimination hair 5 faces the direction of taking out the electric device. Moreover, the static elimination hair 5 consists of an electroconductive fiber provided with electroconductivity and flexibility.

  FIGS. 3A and 3B are diagrams showing a configuration of the static eliminating brush portion 2 before being attached to the bag body 1a, wherein FIG. 3A is a plan view and FIG. 3B is a cross-sectional view taken along line AA in FIG. As shown in FIG. 3, the support portion 3 is configured by, for example, bonding a pair of conductive tapes 30 a and 30 b having a constant width and a length L with, for example, an adhesive, and one end portion of the static elimination hair 5 is An adhesive is sandwiched between the tapes 30a and 30b. The conductive tapes 30a and 30b are made of, for example, aluminum tape. The length L of the support part 3 is determined by the peripheral length of the opening part of the bag 1a. The thickness of the tapes 30a and 30b is, for example, 0. The thickness may be about several mm, and it is preferable to have a thickness with flexibility so that it can be easily attached to the periphery of the opening of the bag 1a.

  In FIG. 3B, one end of the static elimination hair 5 is supported so as to be sandwiched between a pair of conductive tapes 30a and 30b. However, the present invention is not limited to this, and the end is generally supported. Any configuration can be used. For example, FIG. 4 shows another example of such a support structure. That is, FIG. 4 is another example of the cross-sectional configuration of the static elimination brush unit 2, and corresponds to FIG. As shown in FIG. 4, the support portion 3 is formed by, for example, bending a single conductive tape having a constant width and length L into a substantially U-shaped cross section, and the static elimination hair 5 is formed in the U-shaped opening. A conductive double-sided tape 31a is disposed between one surface of the one end portion and the inner surface of the support portion 3 facing the one end portion, and faces the other surface of the one end portion. Another conductive double-sided tape 31b is disposed between the inner surface of the supporting unit 3 and the charge removing unit 5 is attached to and supported by the supporting unit 3 by a pair of double-sided tapes 31a and 31b.

  In FIG. 3, the static elimination hair 5 extends in a direction substantially orthogonal to the longitudinal direction of the support portion 3. The neutralizing hairs 5 are arranged at equal intervals (pitch d), for example, along the longitudinal direction of the support portion 3.

  The neutralizing hair 5 can be formed of, for example, stainless fiber, carbon fiber, or Sandalon (registered trademark) fiber. The thickness of the fiber line can be, for example, about several μm to several tens of μm. The pitch d is, for example, 0. It can be set to several mm to several mm. In addition, these numerical values are examples and are not limited to these. In FIG. 3A, the length of the static elimination hair 5, specifically, the length of the portion pulled out from the support portion 3 is represented by C. The size of C will be described later.

  FIG. 5 is a cross-sectional view showing a bonding structure between the bag body 1a and the charge eliminating brush portion 2, and shows the vicinity of the opening periphery 15 in an enlarged manner. As shown in FIG. 5, on the outer surface of the opening peripheral edge 15 of the bag 1a, the support part 3 of the static elimination brush part 2 is interposed via a conductive double-sided tape 35 having substantially the same shape as the tapes 30a and 30b. It is stuck. Specifically, one surface of the double-sided tape 35 is attached to the outer surface of the bag body 1a, and the other surface of the double-sided tape 35 is attached to the surface of the tape 30b. Moreover, the static elimination hair 5 is extended | stretched in the opening direction which is a direction substantially orthogonal to the circumferential direction of the opening part 70. As shown in FIG. It can be said that the structure which sticks the support part 3 on the outer surface of the bag 1a is preferable in that the support part 3 does not come into contact with the electric device when the electric device is stored or taken out. In addition, the support part 3 can also be stuck on the inner surface of the bag 1a. In this case, in FIG. 5, the outer surface of the tape 30a and the inner surface of the bag 1a may be attached with a double-sided tape.

  FIG. 6 is a schematic diagram showing a state in which the electric device 50 is stored in the storage bag 1. In addition, the same code | symbol is attached | subjected to the component same as FIG. Here, the electric device 50 will be described. In the present embodiment, “electrical equipment” means, for example, circuit boards, electronic components, and all other equipment that may be adversely affected by electrostatic charging. In FIG. 6, for example, a circuit board is stored in the storage bag 1 as the electric device 50.

  Next, the operation of the present embodiment will be described. FIG. 7 is a diagram for explaining the operation of the present embodiment. When the electric device 50 is conveyed in a state of being stored in the storage bag 1, static electricity is charged by contact friction with the inner surface of the storage bag 1. Furthermore, when the electric device 50 is taken out from the storage bag 1, static electricity is charged by contact friction with the inner surface of the storage bag 1. However, in the present embodiment, as shown in FIG. 7, when the electric device 50 is taken out, the tip of the static elimination hair 5 of the static elimination brush portion 2 comes into contact with the surface of the electric device 50, so the electrostatic charge is eliminated. . That is, when the electric device 50 is taken out from the storage bag 1, for example, the electric device 50 is charged by being taken out so that one surface of the electric device 50 is in sliding contact or sliding contact with the static elimination hair 5 of the static elimination brush portion 2. Can be erased. Thereby, the dielectric breakdown of the electric device 50 does not occur due to electrostatic discharge as in the prior art, and the product quality of the electric device 50 can be maintained.

  The length of the neutralizing hair 5 is preferably set to such a length that the tip of the neutralizing hair 5 can easily come into contact with the surface of the electric device 50 when the electric device 50 is taken out of the storage bag 1. From such a viewpoint, the length C (see FIG. 3) of the static elimination hair 5 is preferably about 5 cm to 15 cm, for example. For example, when C = 10 cm, the tip of the static elimination hair 5 is in uniform contact with the surface of the electric device 50, which is suitable for static elimination. However, the length C of the static elimination hair 5 may be set to a size other than this, and the preferred value varies depending on the size of the storage bag 1 and the object to be stored in detail.

  As shown in FIG. 7, when the electric device 50 is taken out from the storage bag 1, if the electric device 50 is taken out along the direction inclined with respect to the opening direction of the storage bag 1, the static elimination hair 5 It is more preferable in terms of static elimination because it comes into contact with the surface of the electric device 50 more reliably.

  Furthermore, when the electric device 50 is taken out from the storage bag 1, it is more preferable that the opposite surfaces of the electric device 50 are taken out in contact with the static elimination hair 5 because the electric charge can be removed from both surfaces of the electric device 5. .

  The principle of static electricity removal by the static elimination brush unit 2 is well known. For example, when the static elimination hair 5 comes into contact with the charged body, the charge of the charged body quickly moves as a leakage current toward the static elimination hair 5 and decreases. In addition, even when the static elimination hair 5 is not in contact with the charged body, if its tip is sufficiently close to the charged body, an unequal electric field is formed between the charged body and the result, in the vicinity of the static elimination hair 5. Gas ionization occurs, and positive and negative ion pairs are generated. Of these ion pairs, ions of the opposite polarity to the charged body adhere to the charged body and neutralize with the charge of the charged body. Is done.

  As described above, according to the present embodiment, since the static elimination brush portion 2 is provided on the periphery of the opening of the storage bag 1, the tip of the static elimination hair 5 is removed when the electric device 50 is taken out from the storage bag 1. The portion is in sliding contact with the surface of the electric device 50, so that the static electricity charged in the electric device 50 can be removed, and the possibility of the electric device 50 being damaged by electrostatic discharge after taking out is prevented. Quality can be maintained.

  Further, in the present embodiment, since the static elimination brush portion 2 is provided over the entire circumference of the opening portion of the storage bag 1, when the electrical device 50 is taken out from the storage bag 1, the opposite surfaces of the electrical device 50 are easily provided. It can be made to contact with the static elimination hair 5 and can be effectively neutralized.

  On the other hand, in Patent Document 1, the semiconductor component soldered and mounted on the circuit board is discharged by contacting with the neutralizing brush while being flowed by the belt conveyor. Is installed above the belt conveyor, the neutralization brush can contact the upper surface of the circuit board, but cannot contact the lower surface, and the lower surface side cannot be neutralized.

Embodiment 2. FIG.
FIG. 8 is a diagram showing an appearance of a storage bag of the electrical device according to the present embodiment. In FIG. 8, the same components as those in FIG. 1 are denoted by the same reference numerals. As shown in FIG. 8, the present embodiment is different from FIG. 1 in that a ground line 21 is connected to the support portion 3. Specifically, for example, a ground wire 21 provided with a hook clip at one end is connected to the support portion 3 through the hook clip, and the other end (not shown) of the ground wire 21 is grounded. By doing so, the leakage current that has flowed into the static elimination hair 5 at the time of static elimination can be released to the ground via the conductive support portion 3 and the ground wire 21, and the static elimination efficiency is improved.

  Moreover, FIG. 9 is another figure which shows the external appearance of the storage bag of the electric equipment which concerns on this Embodiment. In FIG. 9, the same components as those in FIG. 8 are denoted by the same reference numerals.

That is, in FIG. 8, the ground wire 21 is detachable from the storage bag 1, whereas in FIG. 9, the ground wire 22 is fixed to the storage bag 1 in advance. Further, the other end (not shown) of the ground wire 22 is grounded. By doing so, the leakage current that has flowed into the static elimination hair 5 at the time of static elimination can be released to the ground via the conductive support portion 3 and the ground wire 22, and the static elimination efficiency is improved. Further, since the ground wire 22 is fixed to the storage bag 1 in advance, it is possible to save the trouble of preparing and connecting the ground wire each time at the transport destination.

Thus, it has not been conventionally recognized that the electric device 50 taken out of the storage bag 100 has a large surface potential, that is, the electric device 50 is charged with static electricity due to contact friction with the inner surface of the storage bag 100.

  In FIG. 10B, the electric device 50 is taken out from the storage bag 1 (FIG. 1) of Embodiment 1, and the substrate potential at each point P1 to P6 on the surface of the electric device 50 is measured. The storage bag 1 is provided with a static elimination brush portion 2. The measurement result of the substrate potential is shown in “With neutralizing brush” in FIG. That is, the potential of P1 is 78 (V), the potential of P2 is 50 (V), the potential of P3 is 68 (V), the potential of P4 is 55 (V), the potential of P5 is 92 (V), and the potential of P6 Is 95 (V), which indicates that the substrate potential is significantly lower than that of the “conventional”, and the neutralization effect by the neutralization brush portion 2 is remarkable.

  In FIG.10 (c), the electric equipment 50 was taken out from the storage bag 1 (FIG. 8) of this Embodiment, and the substrate potential in each point of P1-P6 of the surface of the electric equipment 50 was measured. The storage bag 1 is provided with a static elimination brush portion 2 and connected to a ground wire 21. The measurement result of the substrate potential is shown in “With grounding static elimination brush” in FIG. That is, the potential of P1 is 25 (V), the potential of P2 is 17 (V), the potential of P3 is 12 (V), the potential of P4 is 7 (V), the potential of P5 is 32 (V), and the potential of P6 Is 45 (V), which indicates that the substrate potential is significantly lower than that of “conventional”, and that the substrate potential is further decreased as compared to “with neutralizing brush”.

  As described above, according to the present embodiment, since the ground wire 21 or 22 is connected to the support portion 3 and the static elimination brush portion 2 is grounded, the electric device 50 is taken out from the storage bag 1. Further, it is possible to perform static elimination more effectively than in the first embodiment. The remaining effects of the present embodiment are the same as those of the first embodiment.
