The feeder 100 has an engagement portion, not shown, with which the claw portion 8 and the letter T-shaped groove portion 13 are detachably engaged, and the housing 1 can be assembled to the feeder 100. The claw portion 8 and the letter T-shaped groove portion 13 are engaged with the engagement portions, respectively, and the housing 1 is detachably assembled to the feeder 100. In the case 1 assembled to the parts feeder 100 in this manner, the parts feeder 100 is vibrated in a state where the discharge port 6 is opened, and the electronic components 50 are lowered along the inclined surface 7a and discharged from the discharge port 6. The discharged electronic component 50 is supplied to the mounting device as described above.

Next, the component housing apparatus 200 according to the embodiment will be described with reference to fig. 5 to 10.

Fig. 5 is a plan view showing an outline of the component housing apparatus 200, and fig. 6 is a partial sectional view corresponding to a line VI-VI in fig. 5.

The component storage device 200 is a device that automatically stores a plurality of electronic components 50 in the storage space S in the housing 1 via the discharge port 6. As shown in fig. 5 and 6, the component housing apparatus 200 of the embodiment includes: a conveying unit 210 for conveying the electronic component 50; a discharging unit 230 that drops and discharges the electronic component 50 from the conveying unit 210; a setting part 240 for setting the above-described housing 1; and a component detection section 270.

The conveying unit 210 continuously conveys the plurality of electronic components 50 to the discharge unit 230. The conveyance unit 210 of the embodiment includes: a linear feeder 211 that linearly and continuously conveys a plurality of electronic components 50; and a turntable 212 that receives the plurality of components conveyed by the linear feeder 211 one by one, and intermittently conveys the components by rotating the electronic components 50 by a rotating operation.

The plurality of electronic components 50 are conveyed toward the turntable 212 by the substantially horizontally arranged linear feeders 211 in a state of being arranged in 1 row. The linear feeder 211 is vibrated by a vibrator, not shown, for example, and the electronic components 50 are sequentially conveyed in the direction of the arrow F toward the turntable 212 by the vibration. The electronic component 50 is conveyed on the linear feeder 211 while being pressed by the subsequent electronic component 50. The linear feeder 211 extends toward the rotation center of the turntable 212, and its distal end portion reaches the vicinity of the outer peripheral edge of the turntable 212.

The turntable 212 is a horizontally disposed disk-shaped rotary member. The turntable 212 is made of ceramic, glass epoxy, or the like. The turntable 212 is rotatably disposed on a base 214 via a rotation shaft 213 extending in the vertical direction. Turntable 212 is intermittently rotated in the direction of arrow R in fig. 5 around rotation shaft 213 by drive source 217 that drives rotation shaft 213 to rotate. A plurality of notches 215 opened on the outer peripheral side are arranged at equal intervals in the circumferential direction on the outer peripheral edge of the turntable 212. The 1 electronic component 50 is accommodated in the 1 notch 215. The rotation direction of the turntable 212 is not limited to the R direction in fig. 5, and may be the reverse direction of the R direction.

As shown in fig. 6, the turntable 212 is disposed on the upper surface 216 of the base 214. The notch 215 is opened on the outer peripheral surface side and upper and lower surfaces of the turntable 212. The turntable 212 includes an unillustrated air suction passage therein that communicates with each notch 215. The air suction passage is open on the inner surface of each notch 215. The air suction passage communicates with a suction source such as a vacuum pump, and the suction source operates to suck air in the notch 215 toward the back surface to be in a negative pressure state. Thus, the electronic component 50 accommodated in the notch 215 is attracted to the back surface by the negative pressure action, and is held in the notch 215.

The electronic components 50 conveyed to the vicinity of the turntable 212 by the linear feeder 211 are stored in each of the plurality of notches 215 of the intermittently rotating turntable 212 from the side, and are sucked and held on the back surface as described above. The electronic component 50 stored and held in the notch 215 is intermittently conveyed to the discharge section 230 in the direction of arrow R by the rotation of the turntable 212. The electronic component 50 accommodated in the notch 215 moves on the upper surface 216 of the base 214.

The discharge unit 230 is disposed corresponding to the turntable 212. Specifically, the discharge unit 230 is disposed on a circular conveyance path corresponding to the rotation locus of the notch 215 of the turntable 212. The discharging unit 230 is disposed at a rotational angle position rotated by approximately 270 ° with respect to the transfer portion transferred from the linear feeder 211 to the turn table 212. The discharge unit 230 is a portion that drops the electronic components 50 conveyed by the turntable 212 toward the discharge port 6 of the housing 1 provided in the installation unit 240 one by its own weight.

As shown in fig. 7, the discharge unit 230 includes a cylindrical member 231 and a pressing pin 236. In the discharge portion 230, a through hole 218 corresponding to the notch 215 of the turntable 212 is provided in a portion directly below the turntable 212. The passage hole 218 has a size through which the electronic component 50 passes. Further, the ejection portion 230 is provided with a suction release mechanism, not shown, for releasing the suction and holding of the electronic component 50 by the air suction in the notch 215. The suction release mechanism may be, for example, a mechanism that discharges air to stop or weaken the flow of the sucked air. When the turntable 212 rotates and the notch 215 is aligned with the through hole 218, the holding of the electronic component 50 in the notch 215 is released by the suction release mechanism, and the electronic component 50 moved on the upper surface 216 of the base 214 falls from the notch 215 to the through hole 218, and further falls into the cylindrical member 231 through the through hole 218.

Further, it is preferable that the inner diameter of the upper tube 233 is larger than the longitudinal dimension of the electronic component 50, and the inner diameter of the lower tube 234 is larger than the longitudinal dimension of the electronic component 50 and smaller than the inner diameter of the upper tube 233.

The electronic component 50 dropped through the through hole 218 passes through the inside of the cylindrical member 231 having a funnel shape, and is guided toward the discharge port 6 of the housing 1. The cylindrical member 231 includes an upper cylindrical portion 233 having an inverted conical shape whose inner diameter increases upward, and a lower cylindrical portion 234 extending downward from the center of the lower end of the upper cylindrical portion 233. The upper tube 233 and the lower tube 234 are integral. The electronic component 50 passed through the passage hole 218 falls down to the inside of the upper tube 233 to reach the inside of the lower tube 234, and passes through the inside of the lower tube 234 to fall. The electronic component 50 may slide down while contacting the inner surface 232 of the cylindrical member 231.

In order to suppress the electronic component 50 from being electrically damaged by static electricity generated by friction, at least the inner surface 232 of the cylindrical member 231 is preferably made of a material containing a conductive material such as a metal having conductivity. In order to smoothly slide down the electronic component 50, the inner surface 232 of the cylindrical member 231 is preferably a smooth low friction surface, and is preferably surface-processed with a resin such as a fluororesin.

The ejection portion 230 is provided with a pressing pin 236 that forcibly drops the electronic component 50 from the notch 215. The pressing pin 236 is disposed at a position above the notch 215 aligned with the through hole 218. The pressing pin 236 is a rod-shaped member extending in the vertical direction, and is driven in the vertical direction by an actuator or the like not shown. When the pressing pin 236 is driven downward, the electronic component 50 in the notch 215 is pressed downward, and the electronic component 50 drops into the cylindrical member 231 through the through hole 218. By pressing the pressing pin 236, the electronic component 50 can be reliably detached from the notch 215 and dropped without being caught in the notch 215.

In addition, an air flow generating portion 237 for dropping the electronic component 50 from the notch 215 by the flow of air may be provided in the discharge portion 230 instead of or in addition to the pressing pin 236. Examples of the air flow generating portion 237 include an air flow generating portion having a function of blowing air to the electronic component 50 from above to cause the electronic component to fall down, or sucking air from a side to cause the electronic component 50 to fall down.

The discharging unit 230 is further provided with a cleaning unit 238, and the cleaning unit 238 cleans a path of the electronic component 50 passing through the discharging unit 230. Specifically, the cleaning portion 238 is disposed above the pressing pin 236, and is constituted by an air suction mechanism that sucks air. By sucking air in through the cleaning portion 238, air in the gap 215, the through hole 218, and the inside of the cylindrical member 231, that is, in the path of the electronic component 50 is sucked in. Thereby, debris, dust, and the like present in the path are sucked into the cleaning portion 238 and cleaned.

The cleaning unit 238 may be a member that blows off debris, dust, or the like by blowing air to clean the path of the electronic component 50. In this case, in order to prevent debris, dust, and the like from entering the housing 1, the cleaning unit 238 is preferably operated in a state where the discharge port 6 is closed by the opening/closing member 3.

Fig. 8 shows a state where the housing 1 is provided in the setting section 240. The housing 1 is disposed in the installation portion 240 in a state where the electronic component 50 positioned to be discharged from the discharge portion 230 is dropped toward the discharge port 6. The housing 1 is disposed in the installation portion 240 in a state in which the front-back direction of the housing 1 is along the vertical direction, that is, in a vertical state.

The installation portion 240 includes a wall portion 241, a holding portion 250 for holding the housing 1 in a vertical state on the wall portion 241, and an opening/closing mechanism 260 for opening/closing the opening/closing member 3 of the housing 1.

The wall portion 241 has a wall surface 241a which is a surface along a substantially vertical direction.

The holding portion 250 includes an upper hook portion 251 and a lower hook portion 252, which are a pair of upper and lower hook portions protruding from the wall surface 241 a. The upper hook 251 and the lower hook 252 have the same shape, and are plate pieces having a letter L shape in side view with their distal ends bent upward by substantially 90 °. As shown in fig. 9, front-side claw portions 8A of case 1 are detachably engaged with upper-side hook portions 251, and rear-side claw portions 8B of case 1 are detachably engaged with lower-side hook portions 252. Thus, the housing 1 is detachably held by the holding portion 250 in a vertical state in which the discharge port 6 faces upward and the longitudinal direction, which is the front-rear direction, extends in the vertical direction along the wall surface 241 a. The bottom plate 2D of the case 1 faces the wall surface 241a in parallel with a gap. The upper hook 251 and the lower hook 252 may not have the same shape.

The wall 241 has a recess 242 extending in the vertical direction and opening on the wall 241a side. An opening/closing mechanism 260 for sliding the opening/closing member 3 is disposed in the recess 242. The opening/closing mechanism 260 has a drive pin 261, and the drive pin 261 is provided so as to be movable in the vertical direction along the bottom surface of the concave portion 242. The tip end portion of the drive pin 261 protrudes beyond the wall surface 241 a. The drive pin 261 is supported to be movable in the vertical direction along a guide groove provided on the bottom surface of the recess 242, for example, and is driven to reciprocate in the vertical direction by an actuator or the like. A reader/writer 243 is disposed in the recessed portion 242 of the wall portion 241, and the reader/writer 243 reads and writes information from and to the RFID tag 5. The reader/writer 243 is an example of an information reading/writing unit.

As shown in fig. 9, the drive pin 261 engages with the slider 4 of the case 1 held by the holding portion 250. The opening/closing member 3 of the housing 1 shown in fig. 9 slides forward (upward in fig. 9), the convex portion 4b of the slider 4 is fitted in the front concave portion 26a, and the discharge port 6 is closed by the opening/closing member 3. On the other hand, the drive pin 261 moves upward. When the drive pin 261 is positioned upward, if the case 1 having the discharge port 6 closed by the opening/closing member 3 is held by the holding portion 250, the drive pin 261 is inserted into the lower opening portion 4c of the slider 4 shown in fig. 4 and positioned between the front end plate portion 4d and the rear end plate portion 4 e.

In fig. 9, when the drive pin 261 moves downward from this state, the drive pin 261 contacts the rear end plate portion 4e of the slider 4, and the slider 4 is pressed downward and slides. The slider 4 slides downward, whereby the opening/closing member 3 slides rearward of the housing 1. Then, as shown in fig. 10, the convex portion 4b of the slider 4 is fitted into the concave portion 26b on the rear side, and the opening 3a of the opening-closing member 3 is aligned with the discharge port 6 of the housing 1, so that the discharge port 6 is opened. When the drive pin 261 returns upward from this state, the drive pin 261 contacts the front end plate portion 4d of the slider 4, and the slider 4 is pushed upward and slides. When the slider 4 slides upward, the opening/closing member 3 slides forward of the housing 1, and as shown in fig. 9, the convex portion 4b fits into the concave portion 26a on the front side, and the discharge port 6 is closed by the opening/closing member 3.

The component detection unit 270 detects the electronic component 50 at an arbitrary position on the path from the transport unit 210 to the discharge port 6 of the housing 1 provided in the installation unit 240 of the electronic component 50. The component detecting unit 270 of the embodiment includes a 1 st component detecting unit 271 disposed at a predetermined position on the side of the linear feeder 211 shown in fig. 5, a 2 nd component detecting unit 272 and a 3 rd component detecting unit 273 disposed on the turn table 212, and a 4 th component detecting unit 274 provided in the discharging unit 230 shown in fig. 7.

The 1 st component detecting unit 271 detects the electronic component 50 conveyed by the linear feeder 211 at a fixed position. The 2 nd component detecting unit 272 is disposed on the upstream side of the conveying path of the turn table 212. The 3 rd component detector 273 is disposed downstream of the 2 nd component detector 272 on the conveying path of the turntable 212.

The 1 st component detection unit 271, the 2 nd component detection unit 272, and the 3 rd component detection unit 273 each detect any matter related to the electronic component 50. The 1 st component detection unit 271 has a function of a counter as a passage detection unit that detects passage of the electronic component 50 and counts the number of passages of the electronic component 50, for example. The 2 nd component detecting unit 272 is, for example, an image sensor as a shape detecting unit that detects the shape of the electronic component 50 and detects whether or not the electronic component 50 has a shape defect based on the detected shape. The 3 rd component detector 273 functions as a performance detector for detecting the performance of the electronic component 50, for example. For example, when the electronic component 50 is a capacitor, the performance detection unit is applied to a capacitance sensor or the like that detects whether or not the capacitance has a predetermined value.

The 4 th component detecting portion 274 includes an upstream side passage detecting portion 275 and a downstream side passage detecting portion 276 arranged at respective positions on the upstream side and the downstream side of the cylindrical member 231. The upstream passage detection unit 275 is located upstream of the cylindrical member 231, and functions as a counter functioning as a passage detection unit that counts the number of passages of the electronic component 50 that has passed through the passage hole 218 and entered the cylindrical member 231. The upstream side detection unit 275 uses a known optical sensor including a light emitting element 275a and a light receiving element 275 b. The downstream passage detection unit 276 is located downstream of the cylindrical member 231, and functions as a counter functioning as a passage detection unit that counts the number of passages of the electronic component 50 that have passed through the cylindrical member 231 and entered the discharge port 6 of the housing 1. The downstream-side passage detection unit 276 also uses a known optical sensor including a light emitting element 276a and a light receiving element 276b, similarly to the upstream-side passage detection unit 275. The light sensor may be a type that receives reflection of emitted light from an object, and the light emitting element and the light receiving element may be integrated without being separated.

According to the component housing apparatus 200 of the above embodiment, the electronic component 50 is housed in the case 1 as follows.

The electronic components 50 are transferred to the turntable 212 one by the linear feeder 211. The electronic component 50 is detected by the 1 st component detecting section 271. The number of electronic components 50 conveyed is counted by the 1 st component detection unit 271, for example. 1 electronic component 50 is accommodated from the linear feeder 211 in the notch 215 of the turntable 212 that is intermittently rotating. In the intermittent rotation of the turntable 212, the electronic component 50 in the notch 215 is detected by the 2 nd component detecting portion 272 and the 3 rd component detecting portion 273.

The 2 nd component detecting unit 272 detects, for example, the shape of the electronic component 50, and detects whether or not the electronic component 50 has a shape defect based on the detected shape. The 3 rd component detecting portion 273 detects, for example, the performance of the electronic component 50. When the 2 nd component detecting portion 272 and the 3 rd component detecting portion 273 determine that the electronic component is a defective product, the electronic component 50 is excluded from the turntable 212.

The electronic components 50 are conveyed one by the turntable 212 to the discharge section 230. In the discharge portion 230, the pressing pin 236 descends while the notch 215 is aligned with the through hole 218, and the electronic component 50 is pressed downward. The electronic component 50 falls from the notch 215 to the through hole 218, further passes through the through hole 218, enters the inside of the cylindrical member 231, falls into the cylindrical member 231, falls from the discharge port 6 of the housing 1 into the housing 1, and is stored therein. At this time, the upstream passage detecting portion 275 of the 4 th component detecting portion 274 detects that the electronic component 50 dropped from the notch 215 enters the cylindrical member 231, and the downstream passage detecting portion 276 detects that the electronic component 50 dropped from the cylindrical member 231 enters the housing 1.

The above operations are performed continuously, and the plurality of electronic components 50 are housed in the case 1. During the conveyance at the linear feeder 211, the number of conveyed electronic components 50 is counted by the 1 st component detecting part 271. The number of electronic components 50 that have fallen from the notch 215 and are finally accommodated in the housing 1 is counted by the 4 th component detector 274 including the upstream passage detector 275 and the downstream passage detector 276. When the number of electronic components 50 stored in the housing 1 reaches a predetermined number, the conveyance of the electronic components 50 by the conveyance unit 210 is interrupted, and the housing of the electronic components 50 into the housing 1 is restarted after the empty housing 1 is replaced with a new one in the placement unit 240.

As shown in fig. 11, the component housing apparatus 200 according to the embodiment further includes a memory 310 and a server 320. Fig. 11 is a block diagram schematically showing the configuration of a production management system for managing information provided in the component storage apparatus 200. The server 320 is an example of a storage device. The detection information detected by the component detection unit 270 is input to the memory 310. The detection information inputted into the memory 310 is stored in the server 320. The server 320 stores the detection information and the ID corresponding to the RFID tag 5 attached to the housing 1. The server 320 may further include processing conditions of the component storage device 200. The processing conditions refer to the screening range of the electronic components 50, the number of the housed components, and the like. The server 320 is disposed in a facility such as a factory together with other components included in the component storage device 200, or disposed at any place other than the facility. Alternatively, the server 320 may be a cloud server on the internet.

In the case where the 1 st component detection unit 271 is a counter (passage detection unit) that counts the number of passages of the electronic component 50, passage records of the electronic component 50 are input one by one to the memory 310. The number of electronic components 50 that have passed through is provided to server 320 as information and stored.

In the case where the 2 nd component detecting section 272 is an image sensor (shape detecting section) that detects a shape defect by detecting the shape of the electronic component 50, when a defective is detected, the information is input to the memory 310 and supplied to the server 320 to be stored.

When the 3 rd component detecting unit 273 is a performance detecting unit that detects the performance of the electronic component 50, the performance information of the electronic component 50 is input to the memory 310 and supplied to the server 320 to be stored. Specifically, for example, when the electronic component 50 is a capacitor, the function is to provide, as information, performance information indicating that the detected capacitance does not have a predetermined value. Alternatively, the distribution of the capacitances of the plurality of electronic components 50 to be conveyed is provided as information based on the detected capacitances.

In the 4 th component detecting unit 274, the presence or absence of passage of the electronic component 50 detected by the upstream-side passage detecting unit 275 and the downstream-side passage detecting unit 276 is input as information one by one to the memory 310, and is supplied to the server 320 and stored.

With the component housing device 200 of the embodiment, the device itself is given a device number, and the device number is stored in the memory 310. When a failure has occurred in the component storage apparatus 200, the number of failures is input to the memory 310 as failure history information, and is supplied to and stored in the server 320.

In the component housing device 200 of the embodiment, the reader/writer 243 reads and writes the above-described various information with respect to the RFID tag 5 of the case 1, for example, as follows. Further, arbitrary information such as the number of the case 1 (case number) and the case 1 being empty and capable of storing the electronic component 50 from now on may be written to the RFID tag 5 of the case 1 by a reader/writer (not shown) or the like.

When the housing 1 is held by the holding portion 250 of the setting portion 240 and the electronic component 50 starts to be housed, the information about the housing 1 written to the RFID tag 5 is read by the reader/writer 243 of the setting portion 240. The information related to the casing 1 is, for example, the above-mentioned casing number, information as to whether the casing 1 is empty, or the like. When the housing 1 is set in the setting portion 240, the device number and the failure history of the component storage device 200 are written in the RFID tag 5 of the housing 1 set in the setting portion 240.

A plurality of electronic components 50 start to be accommodated in the housing 1. As described above, the plurality of electronic components 50 are successively stored in the housing 1 provided in the installation section 240 from the transport section 210 via the discharge section 230. In the process of storing the electronic component 50, the detection information on the electronic component 50 detected by each of the 1 st, 2 nd, 3 rd, and 4 th

component detection parts

271, 272, 273, and 274 is input to the memory 310, and is supplied to the server 320 to be stored.

The device number of the component storage device 200, which is read by the reader/writer 243 and stored in the server 320, is stored in the server 320 together with the ID corresponding to the RFID tag 5 written with the case number of the case 1. Further, the detection information on the electronic component 50 detected by each of the component 1 detection unit 271, the component 2 detection unit 272, the component 3 detection unit 273, and the component 4 detection unit 274 is stored in the server 320 together with the ID corresponding to the RFID tag 5 of the housing 1.

In this way, in the process of housing electronic component 50 in housing case 1, the detection signal relating to electronic component 50 detected by component detector 270 is stored in server 320. When the storage of a predetermined number of electronic components 50 into the housing 1 is completed, various information about the electronic components 50 stored in the server 320 is supplied to the reader/writer 243 via the memory 310 as necessary, and the RFID tag 5 is written by the reader/writer 243. That is, various information related to the electronic component 50 shared by the server 320 linked with the ID is written to the RFID tag 5. For example, when the electronic component 50 is a capacitor, the reader/writer 243 writes the distribution data of the capacitance of the capacitor detected by the 3 rd component detection portion 273 as the performance detection portion into the RFID tag 5. By reading the information in the RFID tag 5, the distribution data of the capacitance of the electronic component 50 in the housing 1 can be grasped.
