The control device 16 sends a control signal to each device based on a control program, a predetermined mounting condition set in advance, and the like.

For example, the control device 16 causes the board camera 15 to image the board 90 positioned by the board transfer device 11. The control device 16 processes the image captured by the substrate camera 15 to recognize the positioning state of the substrate 90. Further, the control device 16 causes the holding member 30 to collect and hold the component 91 supplied by the component supply device 12, and causes the component camera 14 to image the component 91 held by the holding member 30.

1-2. Configuration Example of Parts Management Device 40 As shown in FIG. 2, the parts management device 40 of the present embodiment is provided in the control device 16 of the parts mounting machine 10. The parts management device 40 can be formed, for example, on a line management device that manages a board production line including a plurality of component mounting machines 10, a host computer that manages a plurality of board production lines, a cloud, or the like.

Further, the parts management device 40 includes an acquisition unit 41 and a storage unit 42 when regarded as a control block. The parts management device 40 may further include a discriminating unit 43. As shown in FIG. 2, the parts management device 40 of the present embodiment includes an acquisition unit 41, a storage unit 42, and a discrimination unit 43. Further, the parts management device 40 executes the control program according to the flowchart shown in FIG. The acquisition unit 41 performs the process shown in step S11. The storage unit 42 performs the processes shown in steps S12 and S13. The determination unit 43 performs the determination and processing shown in steps S14 to S16.

1-2-1. Acquisition unit 41
When the parts 91 are sequentially supplied from the carrier tape 80 having a plurality of cavities 81 containing the parts 91 to be mounted on the substrate 90, the acquisition unit 41 obtains the position information of the cavities 81 containing the parts 91. Acquire (step S11 shown in FIG. 3).

As shown in FIG. 4, the carrier tape 80 includes a plurality of cavities 81, a plurality of feed holes 82, and a cover tape 83. Each of the plurality of cavities 81 houses a component 91. The plurality of feed holes 82 are formed at predetermined intervals in the transport direction of the carrier tape 80 (longitudinal direction of the carrier tape 80). A cover tape 83 is adhered to the upper surface of the carrier tape 80, and the openings of the plurality of cavities 81 are closed.

The cover tape 83 of the carrier tape 80 transported to the collection position PP1 shown in FIGS. 1 and 4 is peeled off so that the holding member 30 can collect the component 91. Specifically, the feeder 121 peels off the cover tape 83 while conveying the carrier tape 80, and positions the plurality of cavities 81 in order at the collection position PP1. As a result, the component 91 housed in the cavity 81 positioned at the sampling position PP1 can be sampled by the holding member 30, and the component 91 can be supplied.

The plurality of cavities 81 are formed at predetermined intervals in the transport direction of the carrier tape 80. The interval T1 of the cavities 81 is appropriately set according to the dimensions of the component 91 to be accommodated and the like. As shown in FIG. 4, in the present embodiment, the interval T1 of the cavity 81 is set to an integral multiple (twice in the figure) of the interval T2 of the feed hole 82. Each time the feeder 121 feeds the carrier tape 80 by a predetermined amount (twice the interval T2 of the feed holes 82 in the figure) and pitch feeds, the cavity 81 is positioned at the sampling position PP1 and one component 91 is supplied. The number of remaining parts 91 remaining on the carrier tape 80 is reduced by one.

Therefore, the acquisition unit 41 can acquire the position information of the cavity 81 in the carrier tape 80 based on the number of the parts 91 supplied from the carrier tape 80. The number of parts 91 to be supplied can be obtained from the feed amount of the feeder 121 pitch-feeding the carrier tape 80. For example, when the leading (first) cavity 81 of the carrier tape 80 is positioned at the sampling position PP1 and one component 91 is supplied, the acquisition unit 41 moves the position of the leading (first) cavity 81 of the carrier tape 80. Acquire the position information indicating.

When the feeder 121 pitch-feeds the carrier tape 80 by the predetermined amount, the second cavity 81 from the beginning of the carrier tape 80 is positioned at the sampling position PP1 and one component 91 is supplied. As a result, the acquisition unit 41 acquires the position information indicating the position of the second cavity 81 from the beginning of the carrier tape 80. The same can be said for the position information indicating the positions of the cavities 81 after the third from the beginning of the carrier tape 80.

Further, when the operator attaches the reel RL0 on which the carrier tape 80 is wound to the feeder 121, the operator reads the identification code attached to the reel RL0 using a reading device. Further, when the feeder 121 is installed in the slot of the component supply device 12, the operator reads the identification code attached to the feeder 121 by using the reading device.

When the feeder 121 is installed in the slot, electric power is supplied from the component mounting machine 10 via the connector, and the feeder 121 is in a state of being able to communicate with the component mounting machine 10. As a result, the slot of the component supply device 12, the identification information of the feeder 121 installed in the slot, and the identification information of the reel RL0 attached to the feeder 121 are associated with each other, and the storage device DS0 of the control device 16 is associated with the slot. Is remembered in. Further, the storage device DS0 records the initial number of components 91 in the carrier tape 80 and the number of remaining components 91 remaining in the carrier tape 80.

Therefore, the acquisition unit 41 acquires the position information of the cavity 81 in the carrier tape 80 based on the initial number of the parts 91 in the carrier tape 80 and the remaining number of the parts 91 remaining in the carrier tape 80. You can also. For example, when the initial storage number of the parts 91 is 5000 points and the remaining number of the parts 91 is 5000 points, the 1st (= 5000-5000 + 1) point component 91 is supplied. In this case, the acquisition unit 41 acquires the position information indicating the position of the cavity 81 at the head (first) of the carrier tape 80.

When the initial capacity of the part 91 is 5000 points and the remaining number of the parts 91 is 4999 points, the 2nd (= 5000-4999 + 1) point component 91 is supplied. In this case, the acquisition unit 41 acquires the position information indicating the position of the second cavity 81 from the beginning of the carrier tape 80. As described above, when the initial capacity of the component 91 is NI0 point and the remaining number of component 91 is NR0 point, the component 91 at the (NI0-NR0 + 1) point is supplied. In this case, the acquisition unit 41 acquires the position information indicating the position of the cavity 81 (NI0-NR0 + 1) th from the beginning of the carrier tape 80.

1-2-2. Memory 42
The storage unit 42 stores the position information of the cavity 81 acquired by the acquisition unit 41 and the identification information for identifying the reel RL0 around which the carrier tape 80 is wound in the storage device DS0 in association with each other (shown in FIG. 3). Step S12).

As described above, the slot of the component supply device 12, the identification information of the feeder 121 installed in the slot, and the identification information of the reel RL0 attached to the feeder 121 are associated with each other to form the control device 16. It is stored in the storage device DS0. Therefore, the storage unit 42 can store the position information of the cavity 81 acquired by the acquisition unit 41 and the identification information for identifying the reel RL0 around which the carrier tape 80 is wound in the storage device DS0 in association with each other. ..

Further, the storage unit 42 can store at least one of the board information, the device information, the holding information, and the mounting information in the storage device DS0 in association with the position information of the cavity 81 and the identification information of the reel RL0. Step S13 shown in FIG. The board information refers to information about the board 90 on which the component 91 is mounted. For example, the board information includes identification information for identifying the board 90, the type of the board 90, information for specifying the mounting position where the component 91 is mounted (for example, a circuit symbol), and the like. The types of the substrate 90 include, for example, a multi-chamfered substrate in which a plurality of substrates 90 are divisible, a single-sided mounting substrate in which the component 91 is mounted on only one of the front surface and the back surface of the substrate 90, and a substrate. A double-sided mounting board on which the component 91 is mounted on both sides (front surface and back surface) of the 90 is included.

The device information refers to the information related to the device DD0 used for mounting the component 91. For example, the device DD0 includes a device that is detachably provided on the component mounting machine 10 such as the mounting head 20, the holding member 30, and the feeder 121. Further, in a substrate production line including a plurality of component mounting machines 10, it is necessary to identify the component mounting machines 10. In this case, the device DD0 includes, for example, the component mounting machine 10. Further, the device information includes identification information for identifying the device DD0, usage conditions of the device DD0, and the like.

The holding information refers to information regarding the holding state of the part 91 when the part 91 is collected and held by the holding member 30. For example, the holding information includes the amount of deviation of the component 91 collected and held by the holding member 30 with respect to the regular holding position, the rotation angle with respect to the regular holding posture, the determination result of the holding state, the location of the image data, and the like. .. The determination result of the holding state is determined by whether or not the deviation amount and the rotation angle of the component 91 collected and held by the holding member 30 are included in the allowable range. The holding information can be obtained by performing image processing on the image captured by the component camera 14, for example.

The mounting information refers to information regarding the mounting state of the component 91 when the component 91 is mounted on the substrate 90 by the holding member 30. For example, the mounting information includes the amount of deviation of the component 91 mounted on the substrate 90 with respect to the regular mounting position, the rotation angle with respect to the regular mounting state, the determination result of the mounting state, the location of the image data, and the like. The determination result of the mounting state is determined by whether or not the deviation amount and the rotation angle of the component 91 mounted on the substrate 90 are included in the allowable range. The mounting information can be obtained, for example, by a visual inspection machine that inspects the component 91 mounted on the substrate 90.

FIG. 5 schematically shows an example of information stored in the storage device DS0. For example, the position information of the cavity 81 of the carrier tape 80 wound around the reel RL0 of the identification information DID1 is indicated by "1", "2", and "3" from the beginning of the carrier tape 80. The component 91 housed in the cavity 81 at the top (first) of the carrier tape 80 is mounted at the mounting position indicated by the circuit symbol R1 on the substrate 90 of the identification information BID1. Further, the component 91 is collected (suctioned) by the holding member 30 (suction nozzle) identified by the nozzle number NZ1 and held and mounted on the substrate 90. Further, the determination results of the holding state and the mounting state of the component 91 are both good (OK).

The same can be said for the component 91 housed in the second and subsequent cavities 81 of the carrier tape 80. Further, the above can be said for the component 91 housed in the carrier tape 80 wound around the reel RL0 of the identification information DID2. For example, the component 91 mounted at the mounting position indicated by the circuit symbol R10 on the board 90 of the identification information BID1 has a defective (NG) determination result in both the holding state and the mounting state.

When the component 91 supplied in units of reel RL0 is managed and the cause of the defect is considered to be the component 91 itself, the operator traces all the components 91 housed in the reel RL0 of the identification information DID1. It is necessary and the tracing work is complicated. On the other hand, the user of the parts management device 40 uses the carrier tape 80 in which the parts 91 whose determination result is defective are wound around the reel RL0 of the identification information DID1 based on the information shown in FIG. It can be known that it was housed in the second cavity 81 from the beginning.

Therefore, the user of the parts management device 40 can easily narrow down the parts 91 to be traced based on the position information of the cavity 81 from the parts 91 supplied from the reel RL0 of the identification information DID1, and the traceability is improved. To do. Further, for example, it is assumed that the component 91 whose determination result is poor is often housed in the cavity 81 on the tail side of the carrier tape 80. The component 91 housed in the cavity 81 on the tail side of the carrier tape 80 has a longer elapsed time from the start of use of the carrier tape 80.

Therefore, it can be estimated that the cause of the defect of the component 91 is, for example, the defect of the storage state of the carrier tape 80. Further, the component 91 housed in the cavity 81 on the tail side of the carrier tape 80 is more susceptible to the pressure of the carrier tape 80 when the carrier tape 80 is wound. Therefore, it can be estimated that the cause of the defect of the component 91 is, for example, the defect of the wound state of the carrier tape 80.

The method of supplying the component 91 includes a wafer supply in which the component 91 is supplied from the wafer WF0 and a reel supply in which the component 91 is supplied from the reel RL0. The wafer WF0 has a part (island) that is partially defective in the manufacturing process, and a part that does not satisfy a predetermined quality is managed as a defective die (Bad Die) on a map. Defective dies are detected in advance by optical inspection or the like, but dies that are not determined to be defective dies may later be found to be defective dies. For a plurality of dies in which such detection omission has occurred, for example, when the manufacturer acquires the distribution of the coordinate positions on the wafer WF0 from the traceability information, the dies may be concentrated in a specific region of the wafer WF0. In this case, the manufacturer modifies the determination condition for determining the quality of the die so that the die can be detected to reduce the omission of detection of the defective die.

However, the parts supply device corresponding to wafer supply is generally more expensive than the parts supply device 12 corresponding to reel supply, the types and number of parts 91 that can be supplied are small, and the replenishment work of the parts 91 is complicated. It is easy to become. Therefore, it is known that the parts 91 arranged on the wafer WF0 are transferred to the reel RL0 to supply the reels.

The carrier tape 80 of the present embodiment accommodates the wafer component 91W, which is the component 91 arranged on the wafer WF0. The XW axis and the YW axis shown in FIG. 6 show an example of orthogonal coordinate axes in the wafer WF0. The wafer parts 91W are arranged, for example, by a predetermined number of minutes in the XW axis direction from a predetermined region (arrangement order is 1) on the origin side of the orthogonal coordinate axes. Next, the wafer parts 91W are arranged in the XW axis direction for a predetermined number of minutes from the region in which the coordinates of the YW axis are increased by one from the predetermined region. In the wafer WF0, the above-mentioned arrangement is repeated, and the parts 91 (wafer parts 91W) arranged on the wafer WF0 can be specified by the above-mentioned arrangement order.

The wafer-related information shown in FIG. 7 includes identification information of the wafer WF0, array information (arrangement order) of the wafer component 91W, array information (coordinate information) of the wafer component 91W, and wafer component information. For example, in the wafer component 91W arranged in the predetermined region (arrangement order is 1), the coordinates in the XW axis direction are indicated by the coordinates XW1, and the coordinates in the YW axis direction are indicated by the coordinates YW1. The wafer component 91W is, for example, a wafer component 91W whose quality is not specified.

For the wafer component 91W arranged in the region where the arrangement order is 1 and the region adjacent to the XW axis direction (the arrangement order is 2), the coordinates in the XW axis direction are indicated by the coordinates XW2, and the coordinates in the YW axis direction are the coordinates YW1. It is indicated by. The wafer component 91W is, for example, a reference member RM0 indicating a reference position of the wafer WF0. The reference member RM0 is provided at a predetermined position on the wafer WF0, and indicates a reference position when the wafer component 91W is taken from the wafer WF0. The reference member RM0 is usually not housed in the carrier tape 80 in order to prevent erroneous mounting.

In the wafer component 91W arranged in the region having the arrangement order 2 and the region adjacent to the XW axis direction (the arrangement order is 3), the coordinates in the XW axis direction are indicated by the coordinates XW3, and the coordinates in the YW axis direction are the coordinates YW1. It is indicated by. The wafer component 91W is, for example, a defective wafer component 91W (defective component BM0). The defective component BM0 is a component found in the manufacturing process of the wafer component 91W, and is usually not accommodated in the carrier tape 80 in order to prevent erroneous mounting.

Similarly, in the wafer component 91W whose arrangement order is arranged in the region of the order AJ1, the coordinates in the XW axis direction are indicated by the coordinates XWA1, and the coordinates in the YW axis direction are indicated by the coordinates YWA1. The wafer component 91W is, for example, a wafer component 91WA having a quality of A rank. Further, in the wafer component 91W whose arrangement order is arranged in the region of the order AJ2, the coordinates in the XW axis direction are indicated by the coordinates XWA2, and the coordinates in the YW axis direction are indicated by the coordinates YWA2. The wafer component 91W is, for example, a wafer component 91WB having a quality of B rank.

Further, in the wafer component 91W whose arrangement order is arranged in the region of the order AJ3, the coordinates in the XW axis direction are indicated by the coordinates XWA3, and the coordinates in the YW axis direction are indicated by the coordinates YWA3. The wafer component 91W is, for example, a wafer component 91WC having a quality of C rank. In this specification, for example, it is assumed that the quality of the wafer component 91W deteriorates in the order of the A-rank wafer component 91WA, the B-rank wafer component 91WB, and the C-rank wafer component 91WC. Further, the method of setting the quality of the wafer component 91W is not limited.

As described above, the wafer WF0 includes various wafer parts 91W. Therefore, in the supply of the component 91 using the carrier tape 80 accommodating the wafer component 91W, there is a request to know the arrangement information of the wafer component 91W in the wafer WF0. In this case, the storage unit 42 stores the arrangement information of the wafer component 91W in the wafer WF0 and the position information of the cavity 81 in which the wafer component 91W is housed in the carrier tape 80 in advance in association with each other before supplying the component 91. It is good to store it in the device DS0.

For example, the storage unit 42 accommodates the arrangement information of the wafer parts 91W whose arrangement order is arranged in the region of the order AJ1, the position information of the cavity 81 in which the wafer parts 91W are housed, and the wafer parts 91W. The identification information of the reel RL0 of the carrier tape 80 is stored in the storage device DS0 in association with the identification information. As a result, the user of the component management device 40 finds that the supplied component 91 is a wafer component 91W, and the wafer component 91W is located in the area of the XW axis coordinate XWA1 and the YW axis coordinate YWA1 on the wafer WF0. It can be known that it was arranged. Further, the user of the parts management device 40 can know that the arrangement order of the wafer parts 91W is the order AJ1 and the quality is the wafer parts 91WA of rank A.

The same can be said for other wafer parts 91W. As described above, in the wafer-related information shown in FIG. 7, the storage unit 42 identifies the position information of the cavity 81 containing the wafer component 91W and the reel RL0 of the carrier tape 80 containing the wafer component 91W. The information can be further associated and stored in the storage device DS0.

The wafer parts 91W are arranged in a predetermined order on the wafer WF0, and are housed in the carrier tape 80 in the arrangement order on the wafer WF0. Therefore, it is sufficient for the storage unit 42 to store the predetermined wafer component 91W housed in the carrier tape 80 in the storage device DS0. Further, the wafer component 91W may be accommodated in a plurality of carrier tapes 80 in the arrangement order in the wafer WF0.

Therefore, the storage unit 42 provides the identification information for identifying the wafer WF0, the identification information for identifying the plurality of reels RL0 around which the carrier tape 80 is wound, and the predetermined arrangement information before supplying the component 91. It can be associated in advance and stored in the storage device DS0. The predetermined arrangement information refers to the arrangement information including the arrangement order in the wafer WF0 of the predetermined wafer component 91W housed in each carrier tape 80.

As shown in FIG. 8, the wafer parts 91W arranged on the wafer WF0 of the identification information WID1 are housed in, for example, the carrier tape 80 of a plurality of (five) reels RL0. Therefore, the identification information WID1 of the wafer WF0 and the identification information DID1 to the identification information DID5 of the plurality of (five) reels RL0 are associated and stored in the storage device DS0. Further, for example, in the reel RL0 of the identification information DID1, the arrangement order of the wafer parts 91W housed in the cavity 81 at the head (first) of the carrier tape 80 is 1, and the wafer parts 91W are in the XW axis direction. The coordinates are indicated by the coordinates XW1, and the coordinates in the YW axis direction are indicated by the coordinates YW1.

In the reel RL0 of the identification information DID2, the arrangement order of the wafer parts 91W housed in the cavity 81 at the head (first) of the carrier tape 80 is the order BJ1, and the coordinates of the wafer parts 91W in the XW axis direction are the coordinates. It is indicated by XWB1, and the coordinates in the YW axis direction are indicated by the coordinates YWB1. From the arrangement order of the wafer parts 91W described above, it can be seen that the carrier tape 80 of the reel RL0 of the identification information DID1 contains (BJ1-1) of the wafer parts 91W.

In the reel RL0 of the identification information DID3, the arrangement order of the wafer parts 91W housed in the cavity 81 at the head (first) of the carrier tape 80 is the order CJ1, and the coordinates of the wafer parts 91W in the XW axis direction are the coordinates. It is indicated by XWC1, and the coordinates in the YW axis direction are indicated by the coordinates YWC1. Similarly, from the arrangement order of the wafer parts 91W, it can be seen that the carrier tape 80 of the reel RL0 of the identification information DID2 accommodates (CJ1-BJ1) wafer parts 91W. The same can be said for the reels RL0 of the identification information DID3 to the identification information DID5.

In the storage method shown in the figure, the number of wafer parts 91W accommodated in the reel RL0 of the identification information DID5 is unknown. Therefore, it is preferable that the storage unit 42 separately stores the number of wafer parts 91W accommodated in the reel RL0 in the storage device DS0. Further, the storage unit 42 can store the arrangement information of the wafer component 91W housed in the arbitrary cavity 81 of each carrier tape 80. Further, the storage unit 42 can also store the arrangement information including the arrangement order of the cumulative wafer parts 91W up to the immediately preceding carrier tape 80. In this case, the reel RL0 of the identification information DID1 which is the first reel RL0 has zero arrangement order of the cumulative wafer parts 91W and does not include the arrangement information.

Here, at least one of a defective wafer component 91W (defective component BM0) included in the wafer WF0, a wafer component 91W having a quality of a predetermined rank or less, and a reference member RM0 indicating a reference position of the wafer WF0 is specified. Let it be SM0. As described above, the defective wafer component 91W (defective component BM0) and the reference member RM0 indicating the reference position of the wafer WF0 are usually not accommodated in the carrier tape 80 in order to prevent erroneous mounting. Further, for example, when the supply of a wafer component 91W of a predetermined quality such as a wafer component 91W of a rank B or higher is required, the wafer component 91W having a quality of a predetermined rank or lower (in this case, the wafer component 91WC of the C rank) is erroneously mounted. In order to prevent the above, the carrier tape 80 may not be accommodated.

Therefore, in the carrier tape 80, the carrier tape 80 in which the wafer component 91W following the specific member SM0 in the arrangement order of the wafer WF0 is carried up and accommodated in the specific cavity 81S, which is the cavity 81 in which the specific member SM0 is scheduled to be housed included. For example, it is assumed that the third cavity 81 shown in FIG. 9 is the specific cavity 81S. In this case, the wafer component 91W to be accommodated in the No. 4 cavity 81 is accommodated in the No. 3 specific cavity 81S. Further, the wafer component 91W to be housed in the cavity 81 of No. 5 is housed in the cavity 81 of No. 4. Hereinafter, the same applies, and the wafer component 91W following the specific member SM0 in the arrangement order of the wafer WF0 is moved up and accommodated in the cavity 81.

In this case, the storage unit 42 may store the specific cavity information including the position and the number of the specific cavities 81S in the storage device DS0 in advance before supplying the component 91. As a result, the component management device 40 can match the arrangement information of the wafer component 91W on the wafer WF0 with the position information of the cavity 81 in which the wafer component 91W is housed on the carrier tape 80. In the above example, the position of the specific cavity 81S is the third cavity 81, and the number of the specific cavities 81S is one.

Further, the carrier tape 80 includes a carrier tape 80 in which the specific cavity 81S scheduled to accommodate the specific member SM0 is set in the empty cavity 81E. For example, it is assumed that the third cavity 81 shown in FIG. 9 is the specific cavity 81S. In this case, the third specific cavity 81S is set to the empty cavity 81E. The empty cavity 81E is an unaccommodated cavity 81 that does not accommodate the wafer component 91W and the specific member SM0. In this case, for example, the wafer component 91W to be accommodated in the No. 4 cavity 81 is accommodated in the No. 4 cavity 81. Hereinafter, the same applies, and the above-mentioned wafer component 91W is not carried forward and accommodated.

In this case, the storage unit 42 may store the empty cavity information including the position and the number of the empty cavities 81E in the storage device DS0 in advance before supplying the component 91. As a result, the component supply device 12 can pitch-feed the carrier tape 80 to the cavity 81 in which the wafer component 91W is housed, and can supply the wafer component 91W. In the above example, the position of the empty cavity 81E is the third cavity 81, and the number of empty cavities 81E is one.

Note that the carrier tape 80 may not be conveyed even if the carrier tape 80 is pitch-fed due to improper installation of the reel RL0. Further, when a mistake in collecting the part 91 occurs, the operator may rewind the carrier tape 80. In these cases, the arrangement information of the wafer component 91W on the wafer WF0 and the position information of the cavity 81 in which the wafer component 91W is housed on the carrier tape 80 do not match.

Therefore, the carrier tape 80 includes a carrier tape 80 in which a predetermined cavity 81 for accommodating the wafer component 91W is set in the empty cavity 81E. In this case, the empty cavity 81E may be set at a predetermined cycle (for example, for each supply of a predetermined number of parts 91). The storage unit 42 may store the empty cavity information including the position and the number of the empty cavities 81E in the storage device DS0 in advance before supplying the component 91.

As a result, the component management device 40 can periodically check whether or not the arrangement information of the wafer component 91W and the position information of the cavity 81 in which the wafer component 91W is housed in the carrier tape 80 are consistent. it can. Also in this case, the component supply device 12 can pitch-feed the carrier tape 80 to the cavity 81 in which the wafer component 91W is housed, and can supply the wafer component 91W.

1-2-3. Discriminating unit 43
The determination unit 43 pitch-feeds the carrier tape 80 and supplies the components 91 in order. The empty cavity information detected when the component supply device 12 supplies the components 91 and the empty cavity stored in the storage device DS0. Determine if the cavity information matches. For example, the discriminating unit 43 causes the substrate camera 15 to image the cavity 81 while the component supply device 12 is supplying the component 91, and the cavity 81 is an empty cavity based on the image captured by the substrate camera 15. It can be determined whether or not it is 81E. Specifically, the discriminating unit 43 determines that the cavity 81 to accommodate the component 91 is an empty cavity 81E when the component 91 is not imaged in the above image.

The discrimination unit 43 continues the supply of the component 91 by the component supply device 12 when the empty cavity information matches, and stops the supply of the component 91 by the component supply device 12 when the empty cavity information does not match. Specifically, the determination unit 43 determines whether or not the empty cavity information matches (step S14 shown in FIG. 3). When the empty cavity information matches (Yes in step S14), the discriminating unit 43 continues the supply of the component 91 by the component supply device 12 (step S15).

When the empty cavity information does not match (No in step S14), the discriminating unit 43 stops the supply of the component 91 by the component supply device 12 (step S16). In this case, the component management device 40 warns the operator that the arrangement information of the wafer component 91W and the position information of the cavity 81 in which the wafer component 91W is housed in the carrier tape 80 do not match. As a result, the operator can confirm the misalignment of the carrier tape 80 and correct the misalignment of the carrier tape 80.

Further, the component supply device 12 can also convey the carrier tape 80 so that the nearest empty cavity 81E reaches the sampling position PP1 when the determination unit 43 determines that the empty cavity information does not match. As a result, the arrangement information of the wafer component 91W and the position information of the cavity 81 in which the wafer component 91W is housed in the carrier tape 80 are matched, and the misalignment of the carrier tape 80 is corrected.

When the component supply device 12 is supplying the component 91, the discriminating unit 43 causes the component camera 14 to image the holding member 30, and the cavity 81 is empty based on the image captured by the component camera 14. It is also possible to determine whether or not the cavity is 81E. Specifically, when the component 91 is not imaged in the above image (the holding member 30 does not hold the component 91), the discriminating unit 43 uses an empty cavity 81E for the cavity 81 to accommodate the component 91. It can be judged that there is.

2. Others In order to prevent erroneous mounting, the carrier tape 80 of the embodiment does not contain the specific member SM0. The component supply device 12 can also supply the wafer component 91W from the carrier tape 80 in which the specific member SM0 is housed. In this case, when the cavity 81 containing the specific member SM0 is detected, the component supply device 12 pitch-feeds the carrier tape 80 to the cavity 81 containing the wafer component 91W, and the wafer component 91W. Can be supplied.

Further, what is described above for the wafer component 91W can also be applied to the component 91 produced in the same production lot. Specifically, it is assumed that the parts 91 produced in the same production lot are housed in a plurality of carrier tapes 80 in the production order. In this case, the storage unit 42 provides the identification information for identifying the production lot, the identification information for identifying the plurality of reels RL0 around which the carrier tape 80 is wound, and the predetermined production information before supplying the component 91. It is preferable to store the information in the storage device DS0 in advance. The predetermined production information includes the production order of the predetermined parts 91 housed in each carrier tape 80. The predetermined component 91 can be, for example, a component 91 housed in the head (first) cavity 81 of each carrier tape 80.

Further, in the carrier tape 80, a predetermined cavity 81 for accommodating the component 91 may be set in the empty cavity 81E. In this case, the storage unit 42 can store the empty cavity information including the position and the number of the empty cavities 81E in the storage device DS0 in advance before supplying the component 91. Then, the determination unit 43 determines whether or not the empty cavity information detected when the component supply device 12 supplies the component 91 and the empty cavity information stored in the storage device DS0 match. You can also do it. Further, the discriminating unit 43 continues the supply of the component 91 by the component supply device 12 when the empty cavity information matches, and stops the supply of the component 91 by the component supply device 12 when the empty cavity information does not match. You can also do it.

3. 3. Parts management method The same applies to the parts management method described above for the parts management device 40. Specifically, the parts management method includes an acquisition process and a storage process. The acquisition process corresponds to the control performed by the acquisition unit 41. The storage step corresponds to the control performed by the storage unit 42. Further, the parts management method can further include a discrimination step. The discrimination step corresponds to the control performed by the discrimination unit 43.

4. An example of the effect of the embodiment According to the parts management device 40, the acquisition unit 41 and the storage unit 42 are provided. As a result, the component management device 40 can store the position information of the cavity 81 in which the supplied component 91 is housed in the storage device DS0 in association with the identification information that identifies the reel RL0. Therefore, the user of the parts management device 40 can easily narrow down the parts 91 to be traced based on the position information of the cavity 81 from the parts 91 supplied from the carrier tape 80 of the reel RL0, and the traceability is improved. To do. The same can be said for the parts management device 40 as described above for the parts management method.
