Description

[Technical field]

[0001] The present invention relates to a component mounting apparatus and a component mounting method for mounting components on a board. [Background technology]

[0002] In a component mounting device, a tape feeder conveys a tape member (carrier tape) on which a large number of components are stored in a row, and the tape feeder mounts the components on a board. Components are supplied to the tape feeder by splicing a subsequent tape member (subsequent tape) to a preceding tape member (preceding tape) with a splicing tape (see, for example, Patent Document 1). In a component mounting device, when the tape feeder detects a seam between the preceding tape and the subsequent tape, the information of the tape feeder is switched to the subsequent tape. However, for various reasons, the seam may not be detected, or may be erroneously detected before the seam is reached. If the seam is not detected normally, a problem occurs in that the component mounting device performs component mounting work based on erroneous information.

[0003] Patent Document 1 discloses a component mounting device that counts the number of remaining components on the leading tape of a tape feeder, and if no splice is detected even when the number of remaining components falls within a specified range, stops the component mounting work and instructs the operator to check the splice (splicing position). After visually checking, the operator continues the component mounting work or executes a process to input the correct number of remaining components. [Prior art documents] [Patent documents]

[0013] An embodiment of the present invention will be described in detail below with reference to the drawings. The configurations, shapes, etc. described below are examples for explanation and can be appropriately changed according to the specifications of the component mounting system, the component mounting device, the tape feeder, and the external device. In the following, the same reference numerals are used for corresponding elements in all the drawings, and duplicated explanations are omitted. In FIG. 1 and in some parts described later, the X-axis (perpendicular to the paper surface in FIG. 1) in the board transport direction and the Y-axis (left-right direction in FIG. 1) perpendicular to the board transport direction are shown as two axes perpendicular to each other in the horizontal plane. In FIG. 1 and in some parts described later, the Z-axis (up-down direction in FIG. 1) is shown as the height direction perpendicular to the horizontal plane.

[0014] First, the configuration of the component mounting system 1 will be described with reference to Fig. 1. The component mounting system 1 is configured to include a component mounting device M and an external device CP that are connected via a communication network NT. The component mounting device M has a function of performing a component mounting operation of mounting components supplied from a tape feeder (component supply means) onto a board. The component mounting system 1 is not limited to having one component mounting device M, and may have two or more components. The external device CP has a function of storing authentication information of an operator, a work history and a judgment result by an operator in the component mounting device M, and supporting the manufacture of a mounted board by the component mounting device M.

[0015] First, the configuration of component mounting apparatus M will be described with reference to Fig. 1. Component mounting apparatus M has a component supplying section 2 that supplies components. A plurality of tape feeders 4 are arranged along the X-axis on the upper surface of a feeder base 3 provided in the component supplying section 2. A dolly 5 on which a plurality of reels 6 are set, on which carrier tapes 7 holding components are wound and stored, is disposed below the feeder base 3. The carrier tape 7 pulled out from the reel 6 is supplied to the tape feeder 4. The tape feeder 4 supplies the components held on the carrier tape 7 to a pick-up position by a mounting head 8 by pitch-feeding the carrier tape 7.

[0016] The mounting head 8 is controlled by a main body control unit 11. The main body control unit 11 is connected to an external device CP via a communication network NT. The mounting head 8 moves in horizontal directions (X-axis direction, Y-axis direction) by a head moving mechanism 14 (FIG. 5) controlled by the main body control unit 11. The mounting head 8 takes out components from the tape feeder 4 of the component supply unit 2 and mounts them on a board 10 positioned on a transport path 9.

[0017] 1, a touch panel 12 and an authentication device 13 operated by the operator are installed at the position where the operator works on the front of the component mounting apparatus M. The touch panel 12 and the authentication device 13 are connected to a main body control unit 11. The touch panel 12 displays various information on its display unit, and the operator uses operation buttons and the like displayed on the display unit to input data, operate the component mounting apparatus M, and perform authentication operations such as inputting the operator's identification information (ID) and password. The authentication device 13 is a device such as a biometric authentication device, such as a camera for face authentication, an infrared sensor for iris authentication, and a fingerprint sensor for fingerprint authentication, as well as a reader for reading a contactless IC card such as an employee ID card of the operator, and is used for authenticating the operator.

[0018] Next, the configuration of the tape feeder 4 will be described with reference to Figures 2 and 3. In Figure 2, the tape feeder 4 is attached with the lower surface of the main body 4a, which is an elongated frame member, aligned along the upper surface of the feeder base 3. The position of the tape feeder 4 is fixed by engaging a locking portion 4b provided on the lower surface of the main body 4a with an end of the feeder base 3. In this state, a feeder controller 24 built into the main body 4a is connected to the main body control portion 11 of the component mounting device M via a connector provided on the locking portion 4b. A sensor 25 for detecting joints, which will be described later, is connected to the feeder controller 24.

[0019] A sprocket 21 is disposed at the front end (right side in FIG. 2) of the tape feeder 4. As shown in FIG. 3, feed pins 21a are provided at equal pitches on the outer periphery of the sprocket 21. The feed pins 21a mesh with feed holes 7b for tape feeding provided at a predetermined pitch in the carrier tape 7. In addition, a tooth surface is provided on the side of the sprocket 21 which meshes with a bevel gear connected to the output shaft of a tape feed motor 22.

[0020] 2 and 3, the sprocket 21 rotates by driving the tape feed motor 22 to rotate, thereby feeding the carrier tape 7. In this tape feeding operation, the sprocket 21 performs an intermittent rotation operation corresponding to a pitch feed pattern, and by controlling the rotation of the tape feed motor 22, the pitch feed speed of the carrier tape 7 is set and the tape is positioned.

[0021] This tape feeding causes the carrier tape 7 to be pulled out from the reel 6. The pulled out carrier tape 7 is led into the tape feeder 4 from its rear end and fed forward along the tape feeding path. The front end of the tape feeder 4 is the position where the mounting head 8 picks up components. The carrier tape 7 is pitch-fed while covered from above by a cover member 23 provided on its top surface.

[0022] 2 and 3, during this pitch feed, the component P (FIG. 4) held in the recess 7a of the carrier tape 7 is picked up by the mounting head 8 through the cutout 23a provided in the cover member 23. The cutout 23a serves as a pick-up position for the mounting head 8 to pick up and remove the component P. Just before reaching this pick-up position, the cover tape 7c attached to cover the recess 7a of the carrier tape 7 is peeled off. Then, the component P exposed in the recess 7a by the peeling of the cover tape is picked up by the mounting head 8 and mounted on the board 10.

[0023] A plurality of openings are provided in front of and behind the cutout portion 23a of the cover member 23. A groove portion 23b for allowing the feed pin 21a to escape is provided in a position corresponding to the sprocket 21 on the front side of the cutout portion 23a. The escape groove portion 23b prevents the feed pin 21a protruding from the feed hole 7b of the carrier tape 7 to the upper surface side from interfering with the cover member 23.

[0024] 2 and 3, an optical sensor 25 is disposed upstream of the cutout portion 23a. An opening 23c is provided directly above the sensor 25. Light from the sensor 25 passes through the sprocket holes 7b of the carrier tape 7 and the opening 23c, thereby detecting the sprocket holes 7b. As described below, when the carrier tape 7 is fed below the cover member 23, this sprocket hole detection makes it possible to detect a joint portion 34 (see FIG. 4) where the carrier tape 7 is spliced.

[0025] Splicing, which joins together the carrier tape 7, is performed when the carrier tape 7 housed on the reel 6 wears out during component mounting operations, causing a shortage of components. Here, splicing will be explained with reference to Figure 4. In Figure 4, 7A indicates the carrier tape 7 that has already been mounted (hereinafter referred to as "leading tape 7A"), and 7B indicates the carrier tape 7 housed in a new tape reel (hereinafter referred to as "following tape 7B").

[0026] In Fig. 4, in tape splicing, the tail of the leading tape 7A and the head of the trailing tape 7B are butted together using a special tool, and splicing adhesive tape 32 is attached to the front and back of the carrier tape 7 in a predetermined area across the butt line. This joins the two leading tapes 7A and the trailing tape 7B together, as shown in Fig. 4(b). This splicing has the advantage that the carrier tape 7 is continuously pitch-fed without interruption, eliminating the need to stop the mounting operation when replenishing components.

[0027] In the component mounting device M shown in this embodiment, during this splicing, not only the adhesive tape 32 for tape joining but also the adhesive tape 33 for closing the feed hole is applied onto the feed hole 7b located near the butt line. The adhesive tape 33 has a slit 33a in the longitudinal direction. This allows the feed pin 21a of the sprocket 21 to protrude upward through the slit 33a when it fits into the feed hole 7b from below, so that tape feeding is not hindered.

[0028] 4, the sprocket hole blocking is performed for the purpose of distinguishing the splice portion 34, where the leading tape 7A and the trailing tape 7B are spliced, from the other portions so that the splice portion 34 can be automatically detected by utilizing the sprocket holes 7b. That is, when the normal portion of the carrier tape 7 passes above the sensor 25, the light from the sensor 25 passes upward through the sprocket holes 7b and the opening 23c at the timing when the sprocket holes 7b are positioned between the sensor 25 and the opening 23c, and the sprocket holes are detected. The sprocket hole detection signal is output repeatedly at intervals corresponding to the sprocket hole pitch.

[0029] In contrast, when joint 34 in which sprocket holes 7b are blocked by adhesive tape 33 passes above sensor 25, sprocket holes 7b are not detected in the area where adhesive tape 33 is attached. Therefore, by continuously monitoring the sprocket hole detection signal from sensor 25, it is possible to detect that joint 34 (seam) where leading tape 7A and trailing tape 7B are spliced ​​together has passed the position of sensor 25 (predetermined position).

[0030] In this way, the tape feeder 4 is a component supply means that sequentially supplies multiple components P on the leading tape 7A and multiple components P on the trailing tape 7B by feeding out a leading tape 7A and a trailing tape 7B, each of which stores multiple components P.

[0031] Next, the configuration of the control system of the component mounting system 1 will be described with reference to Fig. 5. Here, the description will focus on the function of storing the result of the determination as to whether or not the joint between the leading tape 7A and the trailing tape 7B supplied to the tape feeder 4 has passed the position of the sensor 25 (predetermined position). The tape feeder 4, the mounting head 8, the head moving mechanism 14, the touch panel 12, and the authentication device 13 are connected to the main body control unit 11 provided in the component mounting device M. The main body control unit 11 also includes a mounting memory unit 15, a mounting control unit 16, a remaining number measurement processing unit 17, a determination result acquisition means 18, a mounting authentication processing unit 19, and a mounting communication unit 20. The mounting memory unit 15 is a storage device, and stores mounting data 15a, remaining component number data 15b, and the like.

[0032] 5, the external device CP includes an external storage unit 41, an external communication unit 42, an external authentication processing unit 43, and an external storage processing unit 44. The external storage unit 41 is a storage device, and stores operator information 41a, authentication information 41b, judgment result information 41c, and the like. The operator information 41a stores, for each operator who performs work in the component mounting system 1, identification information (ID) that identifies the operator, information regarding the authority of the work, and the like. The information regarding the operator's authority of the work includes information regarding whether the operator is permitted to judge whether the seam between the leading tape 7A and the trailing tape 7B has passed a predetermined position (hereinafter referred to as "seam judgment").

[0033] The authentication information 41b stores information for authenticating an operator when the operator operates the component mounting device M. Specifically, the authentication information 41b includes, for each operator, identification information (ID), a password, biometric data for face authentication, biometric data for iris authentication, biometric data for fingerprint authentication, information on a non-contact IC card, etc. The mounting communication unit 20 and the external communication unit 42 are communication devices, which are connected to each other via a communication network NT and transmit and receive various types of data to and from each other.

[0034] 5, mounting data 15a stores the production model name of the mounted board, a component number (type of component) that specifies the type of component P to be mounted on board 10, the arrangement of tape feeder 4 (component supply position), mounting position (XY coordinates), mounting direction, mounting order, etc. Mounting control unit 16 controls tape feeder 4, mounting head 8, and head moving mechanism 14 based on mounting data 15a to mount components P supplied from tape feeder 4 at the mounting positions on board 10.

[0035] The remaining component number data 15b stores the remaining component numbers on the leading tape 7A and the following tape 7B for each tape feeder 4. When components are removed from the tape feeder 4 during component mounting work, the remaining number measurement processing unit 17 subtracts the remaining component number on the leading tape 7A from the remaining component number data 15b. When a seam is detected in the tape feeder 4 and components are to be removed from the following tape 7B, the remaining number measurement processing unit 17 updates the remaining component number on the leading tape 7A in the remaining component number data 15b to the remaining component number on the following tape 7B. When the following tape 7B is engaged with the leading tape 7A in the tape feeder 4, the remaining number measurement processing unit 17 changes the remaining component number on the following tape 7B in the remaining component number data 15b to the number of components stored in the engaged following tape 7B.

[0036] 5, when authenticating an operator, the mounting authentication processing unit 19 acquires the operator's identification information (ID) and password from the touch panel 12, and biometric data for face authentication, biometric data for iris authentication, biometric data for fingerprint recognition, contactless IC card information, etc. from the authentication device 13. The mounting authentication processing unit 19 transmits the acquired authentication information to the external device CP. An external authentication processing unit 43 of the external device CP compares the operator information 41a and authentication information 41b stored in the external storage unit 41 with the authentication information transmitted from the component mounting device M, and transmits the comparison result to the component mounting device M.

[0037] The mounting authentication processing unit 19 executes a predetermined process based on the received comparison result. For example, if the operator is a registered operator, the mounting authentication processing unit 19 displays an operation screen based on the operator's work authority on the touch panel 12. On the other hand, if the operator is not registered, the mounting authentication processing unit 19 displays a re-authentication screen on the touch panel 12 to prompt the operator to perform authentication again. In this way, the touch panel 12, the authentication device 13, and the mounting authentication processing unit 19 constitute an operator authentication means 40 that authenticates the operator provided in the component mounting apparatus M.

[0038] Note that the authentication of the operator may be performed based on authentication information acquired from both the touch panel 12 and the authentication device 13, or based on only authentication information acquired from the touch panel 12 or only authentication information acquired from the authentication device 13. Also, the on-board storage unit 15 may store the operator information 41a and authentication information 41b, and the on-board authentication processing unit 19 may perform authentication of the operator based on the operator information 41a and authentication information 41b stored in the on-board storage unit 15 without using the external device CP.

[0039] In FIG. 5, determination result acquisition means 18 determines whether or not the joint between leading tape 7A and trailing tape 7B supplied to tape feeder 4 has passed the position of sensor 25 (predetermined position).

[0040] Specifically, when the sensor 25 of the tape feeder 4 detects a joint (joint 34) while the number of remaining components on the leading tape 7A included in the remaining component number data 15b is a predetermined number (e.g., 10) or less, the judgment result acquisition means 18 judges that the joint has normally passed the position of the sensor 25 (predetermined position). In this case, the judgment result acquisition means 18 transmits information identifying the tape feeder 4, information on the leading tape 7A and the following tape 7B, and a passing result associating the date and time when the joint was detected to the external device CP via the mounting communication unit 20. The external storage processing unit 44 of the external device CP stores the received passing result and the like in the external storage unit 41 as judgment result information 41c.

[0041] 5, when sensor 25 detects a seam while the number of remaining components on leading tape 7A is greater than a predetermined number, judgment result acquisition means 18 determines that it is time for the operator to determine the passage of a seam. In addition, when sensor 25 does not detect a seam even if a predetermined number (e.g., 5) of components P are taken out of tape feeder 4 after the number of remaining components on leading tape 7A reaches a predetermined number (e.g., 10), judgment result acquisition means 18 determines that it is time for the operator to determine the passage of a seam (when sensor 25 does not detect a seam at the time when the seam should be detected). The predetermined number is set to a number at which components P on trailing tape 7B will not be supplied from tape feeder 4 even if the seam is overlooked.

[0042] That is, the judgment result acquisition means 18 judges that it is time for the operator to make a judgment when the tape feeder 4 (component supply means) detects a seam (joint 34) or when a predetermined seam is detected. When it is judged that it is time for the operator to make a judgment, the mounting control unit 16 stops the mounting work and causes the touch panel 12 or the like to display a notification screen that notifies the operator that a judgment is required. In addition, the operator authentication means 40 authenticates the operator who is permitted to judge whether or not the seam has passed a predetermined position.

[0043] 5, when the operator is authenticated by the operator authentication means 40, the judgment result acquisition means 18 causes the touch panel 12 to display a judgment input screen for inputting the operator's judgment as to whether or not the seam has passed a predetermined position. When the operator inputs the judgment result from the judgment input screen, the judgment result acquisition means 18 associates information for identifying the tape feeder 4, information on the leading tape 7A and the trailing tape 7B, the date and time when the seam was confirmed, the operator's identification information (ID), and the judgment result, and transmits them to the external device CP via the mounted communication unit 20. The external storage processing unit 44 of the external device CP stores the received judgment result, etc. in judgment result information 41c.

[0044] In this way, the judgment result acquisition means 18 acquires the judgment result of whether or not the joint between the leading tape 7A and the following tape 7B passed a predetermined position by the operator when the operator is authenticated by the operator authentication means 40. The mounting communication unit 20 is a transmission means that associates the operator's identification information (ID) with the judgment result and transmits it to the external device CP.

[0045] An example of the judgment result information 41c will now be described with reference to Fig. 6. In the judgment result information 41c, preceding tape information 50, following tape information 51, date and time 52 when the seam was confirmed, information 53 of the operator who confirmed the seam, and information 54 of the judgment result of the seam are stored for each timing when the seam was confirmed. In the judgment result information 41c, this information is recorded for each tape feeder 4. The preceding tape information 50 is information for identifying the preceding tape 7A of the seam. The following tape information 51 is information for identifying the following tape 7B of the seam.

[0046] The timing when the information 53 of the operator who confirmed the seam and the information 54 of the judgment result of the seam are blank is a record of the passing result when the seam was normally detected by the component mounting device M. For example, when the date and time 52 when the seam was confirmed is "October 1st, aa:aa", the component mounting device M detected that the seam between the leading tape 7A and the trailing tape 7B is "A" and "B", respectively, normally passed through the specified position.

[0047] In Fig. 6, information 53 of the operator who confirmed the seam is information that identifies the operator who performed the seam judgment by visual inspection or other work. In information 54 of the seam judgment result, "◯" indicates that the operator judged that the seam passed the specified position. For example, at the timing of "dd:dd on October 1st," operator "b" judged (confirmed) that the seam between leading tape 7A and trailing tape 7B, "D," had normally passed the specified position.

[0048] In the joint judgment result information 54, "x" indicates that the operator judged that the joint did not pass the specified position. For example, at the timing of "October 1st, gg:gg", the operator "a" judged (confirmed) that the joint between the leading tape 7A and the trailing tape 7B, "G", did not pass the specified position normally.

[0049] In this way, the timing when the seam judgment result information 54 is "◯" or "X" is a record of the judgment result when the operator performed the seam judgment. The manager of component mounting system 1 and the quality manager of mounted boards can trace the judgment result of the transfer from leading tape 7A to succeeding tape 7B by checking the contents of judgment result information 41c.

[0050] Next, a component mounting method using tape feeder 4 (component supply means) that sequentially supplies multiple components on leading tape 7A and multiple components on trailing tape 7B by feeding leading tape 7A and trailing tape 7B on which components are stored will be described along the flow of Fig. 7. The following describes the flow during component mounting work in component mounting system 1 as an example.

[0051] If the tape feeder 4 does not detect a seam during component mounting work (No in ST1) and the number of remaining components on the preceding tape 7A does not reach a specified number (e.g., 10), i.e., the preceding tape 7A is not out of components (No in ST2), the component mounting work continues in the component mounting device M.

[0052] 7, when the number of remaining components on the preceding tape 7A reaches a predetermined number (Yes in ST2), the judgment result acquisition means 18 judges whether the tape feeder 4 detects a seam while a predetermined number (e.g., 5 components) of components are taken out from the tape feeder 4 (ST3). If a seam is detected before the predetermined number is reached (Yes in ST3), the judgment result acquisition means 18 judges that the seam has normally passed the predetermined position, and the mounting communication unit 20 (transmission means) transmits the passage result to the external device CP (ST4: passage result transmission step). The passage result and the like transmitted to the external device CP in the passage result transmission step (ST4) are stored in the external storage unit 41 as judgment result information 41c.

[0053] If no seam is detected even when the predetermined number is reached (No in ST3), the judgment result acquisition means 18 judges that a seam judgment by the operator is required, and the mounting control unit 16 stops the component mounting work by the component mounting device M (ST5: component mounting work stopping step). Alternatively, before the remaining number of components on the preceding tape 7A reaches a predetermined number (No in ST2), if the tape feeder 4 detects a seam (Yes in ST1), the component mounting work stopping step (ST5) is executed.

[0054] Thus, (ST1) to (ST3) constitute a timing determination step (ST20) for determining whether it is time to determine whether the seam between leading tape 7A and trailing tape 7B has passed a predetermined position in tape feeder 4 (component supply means). In the timing determination step (ST20), it is determined that it is time to determine whether the seam has passed the predetermined position when the tape feeder 4 detects the seam (Yes in ST1) or when a predetermined seam is detected (No in ST3).

[0055] 7, in the component mounting work stopping step (ST5), if the component mounting device M can be operated from the touch panel 12, the mounting control unit 16 suspends the operation authority from the touch panel 12. This makes it possible to prevent an unauthorized operator from executing a seam judgment.

[0056] Next, the mounting control unit 16 causes the touch panel 12 to display a notification screen to notify the operator that a seam judgment is required (ST6: notification step). Next, the operator authentication means 40 authenticates the operator (ST7: operator authentication step). Thus, when it is determined in the timing judgment step (ST20) that it is time to make a judgment (Yes), the operator authentication means 40 authenticates the operator (ST7). The operator authenticated in the operator authentication step (ST7) is an operator who is permitted to judge whether or not the seam has passed a predetermined position.

[0057] If the operator is authenticated in the operator authentication step (ST7), the judgment result acquisition means 18 acquires the judgment result of whether or not the seam made by the operator has passed a predetermined position (ST8: judgment result acquisition step). In the judgment result acquisition step (ST8), the authenticated operator is allowed to operate the touch panel 12, and the judgment result acquisition means 18 acquires the judgment result from, for example, the operation result of the operator operating the judgment input screen displayed on the touch panel 12. When the operator's judgment result is acquired in the judgment result acquisition step (ST8), the on-board communication unit 20 (communication means) associates the operator's identification information (ID) with the judgment result made by the operator and transmits it to the external device CP (ST9: judgment result transmission step).

[0058] The judgment result etc. transmitted to the external device CP in the judgment result transmission step (ST9) are stored as judgment result information 41c in the external storage unit 41. When the judgment result is transmitted (ST9), the mounting control unit 16 causes the component mounting device M to resume component mounting work (ST10: component mounting work resumption step), and returns to (ST1). By referring to the judgment result information 41c thus stored, it is possible to trace the judgment result of the transfer from the preceding tape 7A to the succeeding tape 7B.

[0059] Next, the configuration of a control system of another embodiment of the component mounting system (hereinafter simply referred to as "component mounting system 1A") will be described with reference to Fig. 8. The component mounting system 1A differs from the component mounting system 1 shown in Fig. 5 in that the result of the joint judgment by the operator is not transmitted to the external device CPA, but is stored as judgment result information 15c in a mounting memory unit 15A provided in a main body control unit 11A of the component mounting device MA. In addition, the external device CPA differs from the external device CP in that it does not include an external storage processing unit 44, and judgment result information 41c is not stored in the external memory unit 41. Hereinafter, the same parts as those in the component mounting system 1 are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0060] When the judgment result acquisition means 18A provided in the main body control unit 11A of the component mounting device MA acquires the result of passage of the seam normally passing through a predetermined position or the judgment result of the seam judgment by the operator, it stores the result as judgment result information 15c in the mounting storage unit 15A. That is, the judgment result acquisition means 18A and the mounting storage unit 15A constitute a storage unit 45 that stores the operator's identification information (ID) in association with the judgment result. By referring to the judgment result information 15c stored in this manner, it is possible to trace the judgment result of the transfer from the preceding tape 7A to the succeeding tape 7B.

[0061] Next, another embodiment of the component mounting method will be described with reference to the flow of Fig. 9. The other embodiment of the component mounting method differs from the component mounting method shown in Fig. 7 in that the result of the seam passing normally through the predetermined position, or the result of the seam judgment by the operator, is not transmitted to the external device CPA but is stored in the component mounting device MA. Hereinafter, the same steps as those in the component mounting method shown in Fig. 7 are given the same reference numerals and detailed description will be omitted.

[0062] 9, when it is determined in the timing determination step (ST20) that the joint has normally passed the predetermined position (Yes in ST3), the storage means 45 stores the passing result as the determination result information 15c (ST31: passing result storage step). When it is determined in the timing determination step (ST20) that it is time to make a judgment (Yes in ST1 or No in ST3), the component mounting work stopping step (ST5), the notification step (ST6), the operator authentication step (ST7), and the judgment result acquisition step (ST8) are executed.

[0063] Next, the storage means 45 associates the operator's identification information (ID) with the judgment result and stores it as judgment result information 15c (ST32: judgment result storage step). Then, the component mounting work resumption step (ST9) is executed, and the process returns to (ST1). By referring to the judgment result information 15c stored in this way, the judgment result of the transfer from the preceding tape 7A to the succeeding tape 7B can be traced.

[0064] As described above, the component mounting apparatus M of this embodiment is equipped with a component supplying means (tape feeder 4) that sequentially supplies multiple components on the leading tape 7A and multiple components on the trailing tape 7B by feeding out the leading tape 7A and the trailing tape 7B, an operator authentication means 40 that authenticates the operator, a judgment result acquiring means 18 that, when the operator is authenticated by the operator authentication means 40, acquires a judgment result as to whether the joint (joint portion 34) between the leading tape 7A and the trailing tape 7B has passed a predetermined position (position of the sensor 25), and a transmitting means (mounting communication unit 20) that associates the operator's identification information (ID) with the judgment result and transmits it to the external device CP.

[0065] This allows an administrator or the like to trace the result of the decision as to whether to switch from the preceding tape 7A to the succeeding tape 7B.

[0066] In the above, the component supply means for sequentially supplying multiple components on the leading tape 7A and multiple components on the trailing tape 7B by feeding out the leading tape 7A and the trailing tape 7B has been described using the tape feeder 4, which transports the leading tape 7A and the trailing tape 7B joined together by adhesive tapes 32 and 33, as an example. However, this component supply means is not limited to the tape feeder 4.

[0067] For example, the component supplying means may be an auto-setting feeder that sequentially transports the leading tape 7A and the following tape 7B without splicing them, and sequentially supplies a plurality of components on the leading tape 7A and a plurality of components on the following tape 7B. In this case, the seam between the leading tape 7A and the following tape 7B is the gap from the tail of the leading tape 7A transported inside the auto-setting feeder to the head of the following tape 7B. Then, from the result of sensor 25 detecting the tail of the leading tape 7A and the head of the following tape 7B, it is detected that the seam has passed a predetermined position (the position of sensor 25).
