A plurality of electronic components 50 are stored in a separated state inside the box body 1.

Furthermore, in this specification, when the box body 1 is set on the feeder 100, the up-down direction of the box body 1 is the up-down direction. In addition, the side of the box body 1 where the discharge port 6 is set is the front, and the opposite side is the rear. The left and right directions such as the left side and the right side are set as the left and right directions when the box body 1 is observed from the front. The first component 21 is located on the right side, and the second component 22 is located on the left side. The front wall portion 2F, the rear wall portion 2B, the right wall portion 2R, and the left wall portion 2L are each a wall portion extending in the lead vertical direction, that is, the up-down direction. The top plate portion 2U and the bottom plate portion 2D are each a plate portion extending in the horizontal direction.

As shown in Fig. 1 and Fig. 4, the box body 1 is composed of a first member 21 and a second member 22 which are symmetrical with each other and are joined together. That is, each of the first member 21 and the second member 22 is a half-split body divided into left and right.

The box body 2 has a discharge port 6 at the lower side of the front wall 2F. The discharge port 6 is a quadrangular opening in the embodiment. The discharge port 6 is not limited to a quadrangular opening, and may be, for example, an opening having a circular or elliptical outline.

As shown in FIG. 2 , the plate member 7 extends between the first member 21 and the second member 22 in the storage space S. The upper surface of the plate member 7 is formed with an inclined surface 7a extending from the rear to the front from the lower edge 6a of the discharge port 6, and the lower edge 6a side is the lowest side. The inclination angle θ of the inclined surface 7a is preferably 3° to 10° relative to the horizontal direction, and more preferably 5° to 7° when the box body 1 is set on the feeder 100.

As shown in FIG. 2 , the gate member 3 for opening and closing the discharge outlet 6 extends continuously from the bottom plate portion 2D to the front wall portion 2F. The gate member 3 opens and closes the discharge outlet 6 by sliding along its own extension direction. The gate member 3 extends continuously from the bottom plate portion 2D to the front wall portion 2F and can slide along its extension direction. The gate member 3 is a thin and long strip-shaped film member. The gate member 3 includes a flexible material such as PET (Polyethylene terephthalate) that has a certain degree of rigidity and can be bent. The width of the gate member 3 is slightly larger than the width of the discharge outlet 6, and has a width that can cover the discharge outlet 6 without a gap.

The gate member 3 has an opening 3a at its front end portion which is substantially the same shape as the discharge port 6. If the opening 3a matches the discharge port 6, the discharge port 6 is opened. If the gate member 3 covers the discharge port 6, the discharge port 6 is closed by the gate member 3. Furthermore, the opening 3a does not need to be the same shape as the discharge port 6, but only needs to have a shape and size that allow the discharge port 6 to open.

A recessed portion 61 is provided on the upper side of the discharge port 6 in the front side wall portion 2F of the box body 2, which is recessed from the outside to the inside. A pair of guide grooves 62 extending in the vertical direction are provided in the thickness direction, i.e., the left-right direction, of the front side wall portion 2F where the discharge port 6 and the recessed portion 61 are provided. The portions of the two sides extending in the length direction of the gate member 3 are respectively inserted into the left and right guide grooves 62. The gate member 3 is guided by the guide grooves 62 to slide the front side wall portion 2F in the vertical direction.

As shown in Fig. 2 and Fig. 3, a circular hole 3b is provided at the rear end of the gate member 3. The slide 4 is installed in a manner that the gate member 3 is integrated by using the hole 3b. The slide 4 is a rectangular parallelepiped member, and as shown in Fig. 4, it has a lower side opening 4c opened downward, and has a front end plate 4d and a rear end plate 4e.

As shown in Fig. 2 and Fig. 3, the slider 4 has flanges 4a extending in the left and right directions at its upper end. The slider 4 has a convex portion 4b on its upper surface. The convex portion 4b is fitted into the hole 3b of the gate member 3 and protrudes upward, whereby the slider 4 and the gate member 3 are integrated.

As shown in FIG. 4 , a recess 23 that is recessed upward and is elongated in the front-rear direction is provided on the bottom plate 2D of the box body 1. A slot 24 is provided on the front surface of the recess 23. The rear end of the gate member 3 is inserted through the slot 24. The rear end of the gate member 3 passes through the slot 24 and extends along the lower surface of the recess 23. A recess 26a and a recess 26b are provided on the lower surface of the recess 23 in a front-rear pair. The protrusion 4b of the slider 4 can be fitted into each of the recess 26a and the recess 26b.

Grooves 25 extending forward and backward are provided on the left and right sides of the bottom plate 2D where the recess 23 is provided. The left and right flanges 4a of the slider 4 are inserted into the left and right grooves 25, respectively. The slider 4 slides forward and backward as the flange 4a slides forward and backward along the groove 25. At this time, the sliding range of the slider 4 is between the position where the projection 4b engages with the recess 26a on the front side and the position where the projection 4b engages with the recess 26b on the rear side.

As shown in FIG3 , when the convex portion 4b of the slider 4 is engaged with the concave portion 26a on the front side, the opening portion 3a of the gate member 3 is located in the concave portion 61 and does not coincide with the discharge port 6. At this time, the discharge port 6 is entirely blocked by the gate member 3, and the electronic component 50 is not discharged from the discharge port 6 to the outside. On the other hand, the gate member 3 slides backward, and when the convex portion 4b is engaged with the concave portion 26b on the rear side as shown in FIG2 , the opening portion 3a of the gate member 3 coincides with the discharge port 6. At this time, the discharge port 6 is open, and the electronic component 50 can be discharged from the discharge port 6.

As shown in FIG. 1 and FIG. 2 , the box body 2 has an upper holding portion 10A and a rear holding portion 10B. The upper holding portion 10A is provided at a pair of grooves at the front and rear ends of the upper side of the box body 2. The rear holding portion 10B is provided at a pair of grooves at the upper and lower ends of the rear side of the box body 2. Each of the upper holding portion 10A and the rear holding portion 10B is held by the robot hand, for example, when the box body 1 is carried by the robot hand.

As shown in Fig. 1 and Fig. 2, a through hole 9 is provided at the lower part of the box body 2 and at a position roughly corresponding to the above-mentioned recessed portion 23. The through hole 9 is a slot-shaped hole extending in the front-back direction. The strip-shaped RFID tag 5 which is long in the front-back direction is attached to the upper surface of the inner part of the through hole 9 and is installed. The RFID tag 5 is a known structure having a transceiver, a memory, an antenna, etc. As shown in Fig. 1, a reader/writer 105 for contactlessly reading and writing information on the RFID tag 5 is arranged on the feeder 100.

As shown in FIGS. 1 to 4 , the box body 2 further includes a claw portion 8 and a T-shaped groove portion 13 extending downward from the outer surface of the bottom plate portion 2D.

The claw portion 8 includes a front claw portion 8A and a rear claw portion 8B. The front claw portion 8A and the rear claw portion 8B are of the same shape, extending from the top to the bottom, and are L-shaped plates with the lower end bent backward by approximately 90 degrees in a side view. Furthermore, the front claw portion 8A and the rear claw portion 8B may not be of the same shape.

The T-groove 13 includes a front T-groove 13A and a rear T-groove 13B. The front T-groove 13A and the rear T-groove 13B are both inverted T-shaped protrusions in front view. The front T-groove 13A has a tapered tapered portion 13c formed at the front end.

The feeder 100 has a not-shown engaging portion, and the claw portion 8 and the T-slot portion 13 are detachably engaged with each other to set the box body 1 on the feeder 100. The claw portion 8 and the T-slot portion 13 are detachably engaged with each other to set the box body 1 on the feeder 100. In the box body 1 thus set on the feeder 100, the feeder 100 vibrates in a state where the discharge port 6 is opened, and the electronic component 50 is discharged from the discharge port 6 along the inclined surface 7a. The discharged electronic component 50 is supplied to the mounting device as described above.

Next, the part storage device 200 of the embodiment will be described with reference to FIGS. 5 to 10 . FIG. 5 is a plan view showing the outline of the part storage device 200 .

The component storage device 200 is a device that automatically stores a plurality of electronic components 50 in the above-mentioned box body 1 through the discharge port 6 in the storage space S. As shown in FIG5 , the component storage device 200 of the embodiment includes: a plurality of installation parts 240, each of which is provided with a plurality of box bodies 1; a plurality of conveying parts 210, each of which linearly and continuously conveys a plurality of electronic components 50 to each of the plurality of installation parts 240; and a discharge part 230, which is arranged between the conveying part 210 and the installation part 240, so that the electronic components 50 fall one by one from the conveying part 210 to the discharge port 6 of the box body 1 provided in the installation part 240 by their own weight.

In the embodiment, three installation sections 240 are provided, and each of the three installation sections 240 is provided with a discharge section 230 and a conveying section 210. The number of installation sections 240 is not limited to three, as long as at least two are provided, and four or more may be provided. In the following description, as shown in FIG. 5 , the conveying lines based on the path of the electronic component 50 from the conveying section 210 to the box body 1 are sometimes referred to as the first conveying line 210A, the second conveying line 210B, and the third conveying line 210C. That is, the part storage device 200 of the embodiment includes the first conveying line 210A, the second conveying line 210B, and the third conveying line 210C.

First, the conveying unit 210 is described. The conveying unit 210 of the embodiment includes: a vibration conveying unit 211, which conveys the components by vibration; and a non-vibration conveying unit 220, which is arranged at the end of the conveying unit 210. The vibration conveying unit 211 and the non-vibration conveying unit 220 are continuously and substantially horizontally arranged, and their upper surfaces become the conveying path of the electronic components 50.

The vibrating conveyor 211 is a major part of the conveyor 210 and is vibrated by a vibrator (not shown). The vibrating conveyor 211 sequentially conveys a plurality of electronic components 50 to the discharge section 230 in the direction of arrow F by vibrating. The electronic components 50 are pushed by the subsequent electronic components 50 and are continuously transported on the vibrating conveyor 211 toward the discharge section 230.

The non-vibration conveying section 220 is arranged between the vibrating conveying section 211 and the discharge section 230. The electronic components 50 conveyed on the vibrating conveying section 211 are transferred to the non-vibration conveying section 220. As shown in FIG6, three partitions 221 are provided at intervals from the upstream side to the downstream side on the upper surface of the non-vibration conveying section 220 to which the electronic components 50 are transferred. Each of the partitions 221 blocks or opens the upper space of the non-vibration conveying section 220, i.e., the passage of the electronic components 50, by moving up and down or reciprocating to the sides using an actuator not shown. FIG6 shows the state in which each partition 221 that blocks the passage of the electronic components 50 on the non-vibration conveying section 220 stops.

When the partition 221 blocks the passage on the non-vibration conveying section 220, the conveyance of the electronic component 50 is stopped by the partition 221. The stopped electronic component 50 is detected by the conveyance component detection section 279 provided on the side of the non-vibration conveying section 220. The conveyance component detection section 279 includes three component detection sections corresponding to the three partitions 221, namely, the first component detection section 271, the second component detection section 272 and the third component detection section 273. The conveyance component detection section 279 will be described later.

The three discharge sections 230 are respectively arranged corresponding to the terminal ends of the non-vibration conveying sections 220 in the three conveying sections 210. The discharge section 230 is a part that drops the electronic components 50 conveyed by the conveying section 210 one by one to the discharge port 6 of the box body 1 provided in the installation section 240 by its own weight.

As shown in FIG7 , the discharge unit 230 includes a plate 212 for receiving the electronic component 50 from the non-vibrating conveying unit 220 of the conveying unit 210, a cylindrical member 231, and a pressing pin 236. The plate 212 has a drop hole 215 for allowing the electronic component 50 to drop toward the cylindrical member 231 below. The electronic component 50 drops into the cylindrical member 231 through the drop hole 215.

The electronic component 50 that falls through the drop hole 215 is guided to the discharge port 6 of the box body 1 by passing through the interior of the funnel-shaped cylindrical member 231. The cylindrical member 231 has an upper cylindrical portion 233 in an inverted cone shape, the inner diameter of which increases as it goes upward, and a lower cylindrical portion 234 that extends downward from the center of the lower end of the upper cylindrical portion 233. The upper cylindrical portion 233 and the lower cylindrical portion 234 are integrated. The electronic component 50 that passes through the drop hole 215 falls to the inner side of the upper cylindrical portion 233 and reaches the interior of the lower cylindrical portion 234, passes through the interior of the lower cylindrical portion 234 and falls. The electronic component 50 has one side in contact with the inner surface 232 of the cylindrical member 231 and the other side is slipping.

In order to suppress the electrical damage of the electronic component 50 due to static electricity generated by friction, it is preferred that at least the inner surface 232 of the cylindrical member 231 is made of a conductive material such as a conductive metal. In addition, it is preferred that the inner surface 232 of the cylindrical member 231 is a smooth low-friction surface so that the electronic component 50 can slide smoothly, for example, it is preferred to perform surface processing on a resin such as a fluorine resin.

The discharge portion 230 is provided with a pressing pin 236 for forcing the electronic component 50 to fall from the drop hole 215. The pressing pin 236 is arranged at an upper position of the drop hole 215 that matches the through hole 218. The pressing pin 236 is a rod-shaped component extending in the up-down direction, and is driven in the up-down direction by an actuator not shown. When the pressing pin 236 is driven downward, the electronic component 50 in the drop hole 215 is pressed downward and falls into the inside of the cylindrical component 231. By pressing with the pressing pin 236, the electronic component 50 in the drop hole 215 is surely released from the drop hole 215 without being caught and falls.

Furthermore, an air flow generating unit 237 for causing the electronic component 50 to fall from the falling hole 215 by the flow of air may be provided in place of the pressing pin 236 or in addition to the discharge unit 230. As such an air flow generating unit 237, for example, one having the function of blowing air from above to cause the electronic component 50 to fall, or one having the function of sucking air from the side to cause the electronic component 50 to fall.

Furthermore, a cleaning section 238 is provided in the discharge section 230, and the cleaning section 238 cleans the path of the electronic component 50 passing through the discharge section 230. Specifically, the cleaning section 238 is composed of an air suction mechanism disposed above the pressing pin 236 and sucking in air. By using the cleaning section 238 to suck in air, the air in the path of the electronic component 50, which is the inside of the drop hole 215 and the cylindrical component 231, is sucked in. Thereby, the debris or dust existing in the path is sucked into the cleaning section 238 and cleaned. Furthermore, the cleaning section 238 can also be a device that cleans the path of the electronic component 50 by spraying air and blowing away the debris or dust. In this case, in order to prevent debris or dust from entering the box body 1, the discharge port 6 can be operated with the door blocking member 3 closed.

Fig. 8 shows a state where the box body 1 is installed in the installation part 240. The box body 1 is installed in the installation part 240 in a state where the electronic components 50 discharged from the discharge part 230 fall into the discharge port 6. The box body 1 is installed in the installation part 240 in a state where the front-back direction of the box body 1 is along the vertical direction, that is, in a longitudinal state.

The installation portion 240 includes: a wall portion 241; a holding portion 250 that holds the box body 1 in a state of being vertically placed on the wall portion 241; and an opening and closing mechanism 260 that opens and closes the door member 3 of the box body 1.

The wall portion 241 has a surface along a substantially vertical direction, namely, a wall surface 241a. The retaining portion 250 includes a pair of upper and lower hook portions protruding from the wall surface 241a, namely, an upper hook portion 251 and a lower hook portion 252. The upper hook portion 251 and the lower hook portion 252 are of the same shape, and are plates having a side L-shaped shape with the front end bent upward by approximately 90°. As shown in FIG. 9 , the front claw portion 8A of the box body 1 is detachably engaged with the upper hook portion 251 from above, and the rear claw portion 8B of the box body 1 is detachably engaged with the lower hook portion 252 from above. Thus, the box body 1 is detachably held in the holding portion 250 in a longitudinal state with the discharge port 6 facing upward and the front-to-back direction, i.e. the length direction, extending in the vertical direction along the wall 241a. The bottom plate portion 2D of the box body 1 has a gap parallel to and opposite to the wall 241a.

A recess 242 extending in the vertical direction and opening to the wall surface 241a is formed in the wall portion 241. An opening and closing mechanism 260 for sliding the door blocking member 3 is arranged in the recess 242. The opening and closing mechanism 260 has a driving pin 261 movably arranged in the vertical direction along the bottom surface of the recess 242. The front end portion of the driving pin 261 protrudes from the wall surface 241a. The driving pin 261 is supported movably in the vertical direction along a guide groove provided in the bottom surface of the recess 242, for example, and is reciprocated in the vertical direction by an actuator or the like. A reader/writer 243 for contactlessly reading and writing information with respect to the RFID tag 5 is arranged in the recess 242 of the wall portion 241. The reader/writer 243 is an example of an information reading and writing unit. Furthermore, the upper hook portion 251 and the lower hook portion 252 may not have the same shape.

As shown in FIG9 , a driving pin 261 is engaged with the slide 4 of the box body 1 held in the holding portion 250. The gate member 3 of the box body 1 shown in FIG9 slides forward (upward in FIG9 ) and the protrusion 4b of the slide 4 is engaged with the recess 26a on the front side, and the discharge port 6 is blocked by the gate member 3. On the other hand, the driving pin 261 moves upward. When the driving pin 261 is located at the upper side, if the box body 1 whose discharge port 6 is blocked by the gate member 3 is held in the holding portion 250, the driving pin 261 is inserted into the lower side opening 4c of the slide 4 shown in FIG4 and is positioned between the front end plate 4d and the rear end plate 4e.

If the driving pin 261 is moved downward from this state in FIG. 9 , the driving pin 261 contacts the rear end plate 4e of the slider 4, so that the slider 4 is pressed downward and slides. As the slider 4 slides downward, the gate member 3 slides toward the rear of the box body 1. As shown in FIG. 10 , the convex portion 4b of the slider 4 is engaged with the concave portion 26b on the rear side, and the opening portion 3a of the gate member 3 matches the discharge port 6 of the box body 1, so that the discharge port 6 opens. If the driving pin 261 is returned upward from this state, the driving pin 261 contacts the front end plate 4d of the slider 4, so that the slider 4 is pressed upward and slides. By sliding the slider 4 upward, the door blocking member 3 slides toward the front of the box body 1, and as shown in FIG. 9, the protrusion 4b is engaged with the recess 26a on the front side, and the opening 3a is closed by the door blocking member 3.

The part storage device 200 of the embodiment is provided with a part detection unit 270, which detects the electronic part 50 at any position of the path of the electronic part 50 between the conveying unit 210 and the discharge port 6 of the box body 1 provided in the installation unit 240. The part detection unit 270 of the embodiment includes: a conveying part detection unit 279 including a first part detection unit 271, a second part detection unit 272 and a third part detection unit 273 shown in FIG5; and a fourth part detection unit 274 provided in the discharge unit 230 shown in FIG7.

The first part inspection unit 271, the second part inspection unit 272, and the third part inspection unit 273 each inspect any item related to the electronic component 50. The first part inspection unit 271, for example, has the function of a counter as a pass inspection unit that detects the passing of the electronic component 50 and counts the number of electronic components 50 that have passed. The second part inspection unit 272, for example, is an image sensor as a shape inspection unit that detects the shape of the electronic component 50 and detects whether the electronic component 50 has a shape defect based on the detected shape. The third part inspection unit 273, for example, functions as a performance inspection unit that detects the performance of the electronic component 50. For example, when the electronic component 50 is a capacitor, the performance inspection unit uses an electrostatic capacitance sensor that detects whether the electrostatic capacitance as a function has a specified value.

The fourth component detection unit 274 includes an upstream side passage detection unit 275 and a downstream side passage detection unit 276 disposed at the upstream side and the downstream side of the cylindrical member 231. The upstream side passage detection unit 275 is located at the upstream side of the cylindrical member 231 and has a function as a passage detection unit counter for counting the number of electronic components 50 that pass through the drop hole 215 and enter the cylindrical member 231. The upstream side passage detection unit 275 uses a known photo sensor composed of a light emitting element 275a and a light receiving element 275b. The downstream side passing detection unit 276 is located on the downstream side of the cylindrical member 231, and has a function as a passing detection unit counter for counting the number of electronic components 50 passing through the cylindrical member 231 and entering the discharge port 6 of the box body 1. The downstream side passing detection unit 276 also uses a known photo sensor composed of a light emitting element 276a and a light receiving element 276b, similarly to the upstream side passing detection unit 275. Furthermore, as a photo sensor, further, as a photo sensor, a method of receiving the reflection of light emitted from an object, and a light emitting element and a light receiving element are not separated but integrated.

According to the component housing device 200 of the above-described embodiment, the electronic component 50 is housed in the box body 1 as follows.

The electronic component 50 is continuously conveyed in the conveying section 210 toward the discharge section 230 by vibration on the vibration conveying section 211. The electronic component 50 transferred from the vibration conveying section 211 to the non-vibration conveying section 220 is pushed by the subsequent electronic component 50 and conveyed toward the discharge section 230, but is stopped at three partitions 221 during the conveying and conveyed. Whenever it stops at each partition 221, the electronic component 50 is inspected by the first component inspection section 271, the second component inspection section 272, and the third component inspection section 273.

In the first component inspection section 271, for example, the number of the electronic components 50 being transported is counted. In the second component inspection section 272, for example, the shape of the electronic component 50 is inspected, and whether the electronic component 50 has a shape defect is inspected based on the inspected shape. In the third component inspection section 273, for example, the performance of the electronic component 50 is inspected.

If the electronic component 50 passing through the non-vibrating conveying part 220 is transferred to the plate 212 and reaches the drop hole 215, it is pressed by the descending pressing pin 236 and falls into the drop hole 215. The electronic component passing through the drop hole 215 falls into the inside of the cylindrical member 231, and then falls into the cylindrical member 231 and falls into the box body 1 from the discharge port 6 of the box body 1 to be accommodated. At this time, the electronic component 50 falling from the drop hole 215 enters the cylindrical member 231 through the detection part 275 on the upstream side of the fourth component detection part 274, and enters the box body 1 through the detection part 276 on the downstream side.

The above actions are performed continuously to accommodate multiple electronic components 50 in multiple (3) boxes 1. The number of electronic components 50 transported is counted by the first component detection unit 271 during the transport of the non-vibrating conveying unit 220. In addition, the number of electronic components 50 dropped from the drop hole 215 and finally accommodated in the box 1 is counted by the fourth component detection unit 274 including the upstream side passing through the detection unit 275 and the downstream side passing through the detection unit 276. When the number of electronic components 50 accommodated in each box 1 reaches a specific number, the conveying unit 210 is interrupted to transport the electronic components 50, and after replacing the setting unit 240 with a new empty box 1, the electronic components 50 are accommodated in the box 1 again. Furthermore, in the above-mentioned continuous operation of the plurality of conveyor lines, namely the first conveyor line 210A, the second conveyor line 210B and the third conveyor line 210C, it is ideal to control each line independently, but the operation of the plurality of conveyor lines can also be controlled synchronously.

In the part storage device 200 of the embodiment, when the box body 1 is set in the setting part 240, various information can be written into the RFID tag 5 of the box body 1 by the reader/writer 243. As the written information, for example, the box body number of the box body 1 to be set, the device number of the device itself, the line number of the conveying line to be set, the failure history of the corresponding conveying line, the batch number of the electronic component 50, the factory number equipped with the part storage device 200, the date related to the manufacturing (manufacturing date, storage date in the box body 1, etc.), the supplier number, etc. can be cited.

According to the above-described embodiment of the parts storage device 200, the following effects can be exerted.

(1) The component storage device 200 of the embodiment is a device for storing a plurality of components from an opening in a box having the aforementioned opening, and includes: a plurality of installation sections 240, each of which is provided with a plurality of box bodies 1; a plurality of conveying sections 210, each of which continuously conveys a plurality of electronic components 50 to each of the plurality of installation sections 240; and a discharge section 230, which is arranged between the conveying section 210 and the installation section 240, so that the electronic components 50 are discharged from the conveying section 210 to the installation section 240. The discharge port 6 of the box body 1 placed in the setting part 240 falls one by one by its own weight; the conveying part 210 includes: a vibrating conveying part 211, which conveys the electronic components 50 by vibration; and a non-vibrating conveying part 220, which is arranged between the vibrating conveying part 211 and the discharge part 230; and in the non-vibrating conveying part 220, a conveying part detection part 279 is provided to detect the electronic components 50 being conveyed in the non-vibrating conveying part 220.

Thus, a large number of electronic components 50 can be automatically stored in the box body 1 in a short time, and component management can be performed by component detection performed by the conveying component detection unit 279. Since the electronic components 50 in a non-vibrating state are detected by the conveying component detection unit 279, the electronic components 50 can be detected with high precision.

(2) In the part storage device 200 of the embodiment, it is preferred that the box body 1 has a gate member 3 that opens and closes the discharge port 6 by sliding, and the setting portion 240 has a holding portion 250 that can hold the box body 1 with the discharge port 6 facing upward, and an opening and closing mechanism 260 that opens and closes the gate member 3.

Since the box body 1 is held in the holding portion 250 of the setting portion 240 with the discharge port 6 facing upward, the electronic component 50 can be smoothly accommodated in the box body 1 from the discharge port 6, and the electronic component 50 will not fall out of the discharge port 6 due to gravity, and a specific number of electronic components 50 can be accommodated reliably. While being held in the holding portion 250, the discharge port 6 of the box body 1 can be easily opened and closed by sliding the shutter member 3 through the opening and closing mechanism 260. By removing the box body 1 from the holding portion 250 while the discharge port 6 is closed by the shutter member 3, the electronic component 50 can be prevented from accidentally spilling out of the discharge port 6 during removal.

(3) In the part storage device 200 of the embodiment, it is preferred that the part transport inspection unit 279 is at least one of a shape inspection unit for inspecting the shape of the electronic part 50, a passage inspection unit for inspecting whether a part has passed, and a performance inspection unit for inspecting the performance of a part.

In this way, the shape or performance of the electronic components 50 housed in the box body 1 can be detected to avoid housing defective products, or the number of the electronic components 50 can be detected to ensure that the expected number of electronic components 50 are housed in the box body 1.

(4) In the part storage device 200 of the embodiment, it is preferred that the box body 1 has an RFID tag 5, and the setting portion 240 has a reader/writer 243 as an information reading/writing portion for reading and writing information from the RFID tag 5 of the box body 1 set in the setting portion 240.

Thus, by reading the RFID tag 5 when the box body 1 is set in the setting part 240, information related to the box body 1 or the electronic component 50 in the box body 1 can be obtained, so that the electronic component 50 can be housed in the box body 1 while the component management is performed.

(5) In the part storage device 200 of the embodiment, it is preferred that the detection information detected by the transport part detection unit 279 is written into the RFID tag 5 by the reader/writer 243.

Thus, by reading the RFID tag 5, the detection information of the electronic component 50 in the box body 1 can be obtained.

The above is an explanation of the embodiments, but the present invention is not limited to the above embodiments, and changes and improvements within the scope of achieving the purpose of the present invention are included in the present invention.
