The present invention is not limited to the specific structures of the following embodiments, and structures obtained based on the same technical concept are included in the present invention.

[0048] (Implementation method 1)

[0049] First, refer to Figure 1 , Figure 2 , a component mounting device according to embodiment 1 of the present invention is described.

[0050] Figure 1 is a schematic perspective view of the component mounting device 1 according to the first embodiment. Figure 2 It is a schematic plan view of the component mounting device 1 .

[0051] Figure 1 , Figure 2 The component mounting device 1 shown is a device for attaching and mounting a leaded component 2 having two leads on a substrate 3. The substrate 3 on which the component 2 is mounted is referred to as a "component mounting substrate".

[0052] Hereinafter, directions orthogonal to each other in the horizontal plane are referred to as the X direction and the Y direction, and a direction perpendicular to the horizontal plane, that is, a vertical direction is referred to as the Z direction.

[0053] The component mounting device 1 includes a substrate holding table 4, a mounting unit 6, a plurality of trays 8, a tray driving unit 10, a component supply unit 12, a component detection sensor 14, and a housing 16 ( Figure 2 ) and the control unit 18. Figure 1 The illustration of the housing 16 is omitted. Figure 2 Component 2 is omitted in the figure.

[0054] The substrate holding stage 4 is a stage that positions and holds the substrate 3 on its upper surface. The substrate holding stage 4 of the first embodiment is movable in the XY directions, but not in the Z direction.

[0055] The mounting unit 6 is a unit that mounts the component 2 on the substrate 3 positioned by the substrate holding stage 4. The mounting unit 6 of the first embodiment includes a moving placement head 20 and an insertion head 22.

[0056] The moving placement head 20 and the insertion head 22 are each a member having a pair of opening and closing claws capable of holding the component 2. The moving placement head 20 and the insertion head 22 are configured to be rotatable in the rotation directions R1 and R2, respectively. Figure 1 The position indicated by the dotted line and the position indicated by the solid line move relative to each other.

[0057] The tray 8 is a component holding portion for holding the component 2. A plurality of trays 8 are provided, and each tray 8 is provided with a holding portion 9 ( Figure 1 ). One tray 8 can hold one component 2 .

[0058] like Figure 1 , Figure 2 As shown, the plurality of trays 8 are connected in a state of being arranged in a row in a ring shape, and are integrally driven to rotate in a rotation direction X1 (positive rotation direction) by a tray driving unit 10. The plurality of trays 8 are conveyed in a ring shape, and each of the trays 8 repeatedly passes through the same path.

[0059] The tray driving unit 10 in the first embodiment is a plurality of pulleys provided inside the plurality of trays 8. The tray driving unit 10 is driven by a servo motor (not shown) and can be driven to rotate in either a forward rotation direction or a reverse rotation direction.

[0060] The component supply unit 12 is a member that supplies the component 2 to the tray 8. The component supply unit 12 is, for example, a tape feeder, and supplies electronic components such as axial components and radial components as the component 2 to the tray 8. The component 2 supplied from the component supply unit 12 to the tray 8 is held by the holding unit 9 of the tray 8. In the first embodiment, the axial component is exemplified as the component 2, but other types of components such as radial components may also be used.

[0061] There are a plurality of component supply units 12, and each component supply unit 12 has the same type of components 2. Figure 1 2 , the component supply section 12 at the right end of the paper is shown as having the component 2 , but the other component supply sections 12 also have the component 2 in the same manner.

[0062] The component detection sensor 14 is a sensor that detects the presence of the component 2 on the tray 8 at a certain position. The component detection sensor 14 may be any sensor that can detect the presence of the component 2, such as a light reflection sensor.

[0063] Figure 2The housing 16 shown is a member for accommodating various components of the component mounting device 1. The housing 16 accommodates at least the substrate holding table 4, the mounting unit 6, the plurality of trays 8, the tray driving section 10, and the component detection sensor 14. The component supply section 12 is connected to the housing 16 in a state where it can supply the components 2 to the tray 8 via the opening 23 provided in the housing 16.

[0064] The housing 16 has an opening and closing cover 24 in the same row as the part connected to the component supply unit 12. The opening and closing cover 24 is a cover that can open and close a part of the housing 16, and the inside of the housing 16 cannot be accessed from the outside except for the opening and closing cover 24. The opening and closing cover 24 is usually closed when the component mounting device 1 is in operation, and when the opening and closing cover 24 is opened, the tray 8 inside can be accessed from the outside of the housing 16. By providing the opening and closing cover 24, the place where the tray 8 can be accessed from the outside of the housing 16 can be limited.

[0065] Although not shown in the figure, a safety switch is provided for detecting that the opening and closing cover 24 is opened. When the opening and closing cover 24 is detected by the safety switch, the operation of the control component mounting device 1 is stopped.

[0066] The control unit 18 controls various components of the component mounting device 1. The control unit 18 includes, for example, a microcomputer and is electrically connected to at least the substrate holding table 4, the mounting unit 6, the tray driving unit 10, the component supply unit 12, and the component detection sensor 14.

[0067] Here, use Figure 3A to Figure 3C An operation example of moving the placement head 20 and the insertion head 22 will be described. Figure 3A to Figure 3C This is a schematic diagram showing the operation sequence of the movable placement head 20 and the insertion head 22 during normal operation.

[0068] like Figure 3A As shown, the mobile placement head 20 approaches the component 2 held by the holding portion 9 of the tray 8 with the opening and closing claws opened, and then closes the opening and closing claws to grasp the main body of the component 2 and receive the component 2 from the tray 8. The mobile placement head 20 that has received the component 2 is shown in FIG. Figure 3B As shown, the insertion head 22 is rotated in the rotation direction R3 and rotated to a position where it can receive the component 2 .

[0069] The insertion head 22 of Embodiment 1 does not move in the XY direction, but can only move up and down in the Z direction. A sliding mechanism may be provided between the moving placement head 20 and the insertion head 22 to slide the component 2 held by the moving placement head 20 laterally toward the insertion head 22 .

[0070] The insertion head 22 receives the component 2 from the mobile placement head 20. Figure 3CAs shown, the insertion head 22 rotates in the rotation direction R4 and descends in the Z1 direction. As the insertion head 22 descends, the leads of the component 2 held by the insertion head 22 are inserted into the substrate 3. Thus, a component mounting substrate in which the component 2 is mounted on the substrate 3 is manufactured.

[0071] like Figure 2 As shown, when the plurality of trays 8 rotate in a circular shape in the rotation direction X1, each of the trays 8 moves so as to pass through the component receiving position A1, the tray access position A2, the component delivery position A3, and the component detection position A4 in this order.

[0072] The component receiving position A1 is a position where the tray 8 receives the component 2 from the component supply unit 12. The component receiving position A1 in the first embodiment is a position facing the plurality of component supply units 12, and is, for example, a position corresponding to eight pitches when the amount of movement of the tray 8 is counted. The tray access position A2 located downstream of the component receiving position A1 is a position where the operator of the component mounting device 1 can access the tray 8. The tray access position A2 in the first embodiment is a position facing the opening and closing cover 24, and is, for example, a position corresponding to two pitches when the amount of movement of the tray 8 is counted. The component delivery position A3 located downstream of the tray access position A2 is a position where the component 2 is delivered from the tray 8 to the mounting unit 6. The component delivery position A3 in the first embodiment is, for example, a position corresponding to one pitch when the amount of movement of the tray 8 is counted. The component detection position A4 located downstream of the component delivery position A3 is a position where the component detection sensor 14 detects the presence or absence of the component 2 on the tray 8. The component detection position A4 in the first embodiment is, for example, a position corresponding to one pitch when the amount of movement of the tray 8 is counted.

[0073] The number of pallet pitches occupied by positions A1, A2, A3, and A4 is not limited to Figure 2 The examples shown may be appropriately changed according to the specifications of the component mounting device 1 and the substrate 3 .

[0074] The tray access position A2 may be set at any position as long as it is between the component receiving position A1 and the component delivery position A3 along the rotation direction X1 of the tray 8. By being arranged between the component receiving position A1 and the component delivery position A3, the operator can visually check and access the component 2 supplied from the component supply unit 12 to the tray 8 at the component receiving position A1 before the component 2 is delivered to the mounting unit 6 at the component delivery position A3.

[0075] The component detection position A4 can be set at any position as long as it is between the component transfer position A3 and the component receiving position A1 along the rotation direction X1 of the tray 8. By being arranged between the component transfer position A3 and the component receiving position A1, it is possible to confirm whether the component 2 transferred from the tray 8 to the mounting unit 6 at the component transfer position A3 remains on the tray 8 before the component receiving position A1 receives a new component 2 from the component supply unit 12.

[0076] Next, an operation example of the component mounting device 1 having the above-mentioned structure will be described. The following operation is executed by the control unit 18 .

[0077] The control unit 18 first drives the tray driving unit 10 to rotate the plurality of trays 8 in the rotation direction X1 as the forward rotation direction. The plurality of trays 8 rotate in a circle while being arranged in a row, and intermittently move in the rotation direction X1 with a small stop time provided for each pitch.

[0078] The necessary components 2 are supplied from the component supply section 12 to the tray 8 stopped at the component receiving position A1 while the plurality of trays 8 are intermittently moved. Information on which component supply section 12 of the plurality of component supply sections 12 delivers the component 2 to which tray 8 is stored in the control section 18 based on a pre-made production schedule.

[0079] The control unit 18 also drives the mounting unit 6 to receive the component 2 of the tray 8 stopped at the component delivery position A3. Figure 3A to Figure 3C The component 2 on the tray 8 is received by the mobile placement head 20, and the component 2 is delivered from the mobile placement head 20 to the insertion head 22, and the insertion head 22 receiving the component 2 is lowered, thereby inserting the lead wire of the component 2 into the insertion hole of the substrate 3. Thus, a component mounting substrate in which the component 2 is mounted on the substrate 3 is manufactured.

[0080] The control unit 18 also detects the presence or absence of the component 2 in the tray 8 stopped at the component detection position A4 through the component detection sensor 14. This detection is performed separately for the tray 8 stopped at the component detection position A4. In the case where the component detection sensor 14 does not detect the component 2, it is assumed that the component 2 is normally delivered from the tray 8 to the mounting unit 6 at the component delivery position A3, and the operation of the component mounting device 1 is continued. On the other hand, in the case where the component detection sensor 14 detects the component 2, it is assumed that the component 2 is not normally delivered from the tray 8 to the mounting unit 6 at the component delivery position A3, resulting in a component insertion error. In the case where a component insertion error occurs, the control unit 18 of Embodiment 1 performs a recovery operation for the component insertion error described below.

[0081] Specifically, when a component insertion error occurs, the control unit 18 controls the operation of the component mounting device 1 so as not to immediately stop the operation of the component mounting device 1 but to automatically feed the tray 8 where the component 2 is detected to a predetermined specified position. The operator confirms that the component 2 on the tray 8 has stopped at the specified position and can perform recovery operations such as removing the component 2. Compared with manually determining the feed amount of the tray 8 when a component is inserted incorrectly, the time required for recovery operations can be shortened, and the operating rate of the component mounting device 1 can be improved. Figure 4 , Figure 5A to Figure 5C The specific actions are described.

[0082] Figure 4 This is a flowchart showing an example of the operation of the component mounting device 1 related to a component insertion error. Figure 5A to Figure 5C It means along Figure 4 This is a schematic plan view of the operation of the tray 8 when the illustrated flowchart is operated.

[0083] like Figure 4 As shown, the control unit 18 detects (the presence or absence of) the components 2 on the tray 8 stopped at the component detection position A4 using the component detection sensor 14 ( S1 ).

[0084] Based on the detection result of step S1 , the control unit 18 determines whether or not there is a component 2 on the tray 8 stopped at the component detection position A4 ( S2 ).

[0085] When it is determined that there is no component 2 ("No" in S2), the control unit 18 feeds the tray 8 by one pitch, supplies the component 2, and inserts the component 2 (S3). Specifically, the tray driving unit 10 feeds the tray 8 by one pitch in the rotation direction X1, the component supply unit 12 supplies the component 2 to the tray 8 at the component receiving position A1, and the mounting unit 6 mounts the component 2 on the substrate 3.

[0086] When the control unit 18 executes step S3, it determines whether the insertion of all components is completed (S4). Specifically, the control unit 18 stores information about the components 2 inserted into the substrate 3 by executing step S3, and determines whether the insertion of all components is completed based on the stored information and pre-stored information related to the number and type of components 2 to be installed.

[0087] If it is determined that all components have been inserted (YES in S4 ), the operation of component mounting device 1 ends. On the other hand, if it is determined that all components have not been inserted (NO in S4 ), control unit 18 executes step S1 again.

[0088] When it is determined based on the detection result of step S1 that the component 2 is present on the tray 8 (YES in S2 ), a component insertion error occurs, and the control unit 18 executes a series of steps S5 to S8 .

[0089] The control unit 18 moves the tray 8 that has detected the component 2 from the component detection position A4 to the tray access position A2 (S5). Figure 5A As shown, the tray driving unit 10 is driven to rotate the plurality of trays 8 in the rotation direction X1 which is the forward rotation direction. The feeding amount of the tray 8 in step S5 is pre-stored in the control unit 18 as the number of tray pitches from the component detection position A4 to the tray access position A2. The tray 8A ( Figure 5A Shown in middle hatching. "Parts Remaining Tray") Figure 5B As shown, it moves to the tray access position A2 and stops.

[0090] The control unit 18 stops the production and notifies the operator ( S6 ). Specifically, the operation of the component mounting device 1 is stopped, and a component insertion error is notified to the operator by sounding a buzzer or displaying an error screen.

[0091] By moving the tray 8A where the component 2 is detected to the tray access position A2 and stopping, the operator can visually check the component 2 by opening the opening and closing cover 24, and can take measures such as removing the component 2. By automatically feeding the tray 8A where the component 2 is detected to the tray access position A2 which is a predetermined position, the time required for the recovery work of the component insertion error can be shortened compared to the case where the operator manually determines the number of feeding pitches of the tray 8. As a result, the operating rate of the component mounting device 1 can be improved.

[0092] exist Figure 5B In the illustrated example, the tray 8A is stopped at a position on the upstream side in the rotation direction X1 at the tray access position A2 corresponding to two pitches, but may be stopped at a position on the downstream side.

[0093] The control unit 18 restarts the production ( S7 ). Specifically, the operator who has finished the recovery work inputs via an interface (not shown) connected to the control unit 18 , and based on the input, the control unit 18 restores the component mounting device 1 to the operating state.

[0094] The control unit 18 moves the tray 8A from the tray access position A2 to the component detection position A4 (S8). Figure 5BAs shown in FIG. 1 , the tray driving unit 10 is driven to rotate the plurality of trays 8 in a rotation direction X2 (reverse rotation direction) opposite to the rotation direction X1. The feed amount (reverse rotation) of the tray 8 in step S8 is set to be the same as the feed amount (forward rotation) of the tray 8 in step S5. The tray 8A stopped at the tray access position A2 is as shown in FIG. Figure 5C As shown, it returns to the component detection position A4 and stops.

[0095] By returning the tray 8A from which the component 2 has been removed to the original component detection position A4, the state at the time of component insertion error can be returned to, and the production schedule prepared in advance can be restarted.

[0096] Furthermore, by setting the rotation direction X2 of the tray 8A in step S8 to be the opposite direction of the rotation direction X1 of the tray 8A in step S5, the return time of the tray 8A can be shortened.

[0097] When step S8 is executed, the control unit 18 executes step S1 again.

[0098] As described above, according to the component mounting device 1 of embodiment 1 and the manufacturing method of the component mounting substrate using the component mounting device 1, when the component 2 of the tray 8A is detected by the component detection sensor 14, the control unit 18 controls the tray drive unit 10 so that the tray 8A where the component 2 is detected moves from the component detection position A4 to the tray access position A2 which is a predetermined specified position and stops.

[0099] According to this structure and method, by moving the tray 8A to a predetermined position and stopping it, the operator can visually confirm the component 2 and remove the component 2, thereby quickly responding to the component insertion error. Compared with the case of manually feeding the tray 8, the time spent on the recovery operation of the component insertion error can be shortened, and the operating rate of the component mounting device 1 can be improved.

[0100] Furthermore, according to the component mounting apparatus 1 and the component mounting substrate manufacturing method using the component mounting apparatus 1 of the present embodiment, the control unit 18 controls the tray driving unit 10 to return the tray 8A stopped at the tray access position A2 as a predetermined position toward the component detection position A4.

[0101] According to such a configuration and method, by returning the tray 8A toward the component detection position A4, production can be resumed from the original state at the time of component insertion error, and a pre-set production schedule can be continued.

[0102] In addition, according to the component mounting device 1 of the present embodiment and the method for manufacturing a component mounting substrate using the component mounting device 1, the rotation direction X1 of the tray 8 when moving from the component detection position A4 to the tray access position A2 and the rotation direction X2 of the tray 8 when returning from the tray access position A2 toward the component detection position A4 are opposite directions.

[0103] According to such a structure and method, by rotating the tray 8 in the reverse direction, the time taken for the tray 8 to return can be shortened.

[0104] In addition, according to the component mounting device 1 of the present embodiment and the method for manufacturing a component mounting substrate using the component mounting device 1, a housing 16 is further provided, and the housing 16 accommodates the mounting unit 6, the plurality of trays 8, the tray driving unit 10, and the component detection sensor 14. The housing 16 is provided with an opening and closing cover 24 at a position facing between the component receiving position A1 and the component delivery position A3, and the predetermined position for stopping the tray 8A is the tray access position A2 facing the opening and closing cover 24.

[0105] According to this structure and method, by providing the opening and closing cover 24, the places where the operator can access the inside of the component mounting device 1 can be limited, and safety can be improved. In addition, by feeding the tray 8A to a position facing the opening and closing cover 24, the operator can visually confirm the components 2 on the tray 8A as long as the opening and closing cover 24 is opened.

[0106] (Implementation method 2)

[0107] A component mounting device according to a second embodiment of the present invention and a method for manufacturing a component mounting substrate using the component mounting device will be described. It should be noted that in the second embodiment, the differences from the first embodiment will be mainly described, and the overlapping descriptions with the first embodiment will be omitted.

[0108] The second embodiment is different from the first embodiment in that a discarding unit for discarding the component 2 is provided and that the component 2 is discarded to the discarding unit when a component is inserted incorrectly.

[0109] Figure 6 This is a schematic perspective view of a component mounting device 100 according to the second embodiment.

[0110] like Figure 6 As shown, the component mounting apparatus 100 includes a discarding unit 102 in addition to the same components as those in the first embodiment. The discarding unit 102 is a unit for discarding the component 2 held by the moving placement head 20 of the mounting unit 6.

[0111] When the component 2 is an axial component, the lead wire of the component 2 is cut in order to mount it on the substrate 3. The lead wire scraps are generated by cutting the lead wires, and the discarding unit 102 is provided as a unit for discarding the lead wire scraps. As described later, the discarding unit 102 is also used to discard the component itself remaining on the tray 8A when a component insertion error occurs. That is, the discarding unit 102 is a unit for discarding "at least a part" of the component 2, especially the axial component.

[0112] The discarding unit 102 of the second embodiment is provided below the moving placement head 20. The component 2 held by the moving placement head 20 and a part thereof can be discarded to the discarding unit 102 by dropping the component 2 and a part thereof.

[0113] The discarding unit 102 may have any structure as long as it can discard the component 2 and at least a part thereof. For example, the discarding unit 102 may be a box-shaped member with an upper opening or a suction member having a suction port connected to a suction source.

[0114] The component mounting device 100 of the second embodiment having the above-mentioned structure is similar to the first embodiment. When a component insertion error occurs, the operation of the component mounting device 100 is not immediately stopped, and the tray 8A where the component 2 is detected is automatically fed to a predetermined specified position. The specified position in the second embodiment is different from the tray access position A2 as the specified position in the first embodiment, and is set to the component transfer position A3.

[0115] Figure 7 This is a flowchart showing an example of the operation of the component mounting device 100 related to a component insertion error. Figure 8A to Figure 8C It means along Figure 7 This is a schematic plan view of the operation of the tray 8 when the illustrated flowchart is operated.

[0116] like Figure 7 As shown, the control unit 18 executes steps S1 to S4 which are the same as those in Embodiment 1. The operation contents of steps S1 to S4 are the same as those in Embodiment 1, and thus the description thereof is omitted.

[0117] When it is determined based on the detection result of step S1 that the component 2 is present in the tray 8A (YES in S2 ), a component insertion error occurs, and the control unit 18 executes a series of steps S10 to S12 .

[0118] Specifically, the control unit 18 moves the tray 8A from the component detection position A4 to the component delivery position A3 (S10). Fig. 8AAs shown in FIG. 1 , the tray driving unit 10 is driven to rotate the plurality of trays 8 in the rotation direction X2 which is the reverse rotation direction. The feeding amount of the tray 8 in step S10 is pre-stored in the control unit 18 as the number of pitches from the component detection position A4 to the component delivery position A3. The tray 8A stopped at the component detection position A4 is as shown in FIG. Figure 8B As shown, it moves to the component transfer position A3 and stops.

[0119] By moving the tray 8A to the component taking-over position A3 and stopping it, the moving placement head 20 of the mounting unit 6 can access the components 2 on the tray 8A.

[0120] The control unit 18 uses the moving placement head 20 to take out the component 2 from the tray 8A and discard the component 2 to the discard unit 102 ( S11 ).

[0121] use Figures 9A to 9C An example of the operation of moving the placement head 20 in step S11 will be described. Figures 9A to 9C 1 is a schematic diagram showing the operation sequence of the movable placement head 20 when a component insertion error occurs.

[0122] like Fig.9A As shown, the mobile placement head 20 approaches the component 2 held by the holding portion 9 of the holding tray 8 with the opening and closing claws opened, and then grasps the main body of the component 2 by closing the opening and closing claws to receive the component 2. The mobile placement head 20 that has received the component 2 is shown in FIG. Fig. 9B The rotating moving placement head 20 does not hand over the held component 2 to the insertion head 22, but opens the opening and closing claws to make the component 2 fall downward. The component 2 that falls downward is stored in the discarding unit 102. The component 2 stored in the discarding unit 102 is then sent to the outside of the housing 16 of the component mounting device 1 and discarded.

[0123] By discarding the components 2 to the discarding unit 102 using the mounting unit 6, the components 2 remaining on the tray 8A can be automatically discarded. Compared with manually removing the components 2, the time required for the recovery work of the component insertion error can be shortened, and the operating rate of the component mounting device 100 can be improved.

[0124] The control unit 18 moves the tray 8A from the component delivery position A3 to the component detection position A4 (S12). Figure 8B As shown in FIG. 1 , the tray driving unit 10 is driven to rotate the plurality of trays 8 in the rotation direction X1 (positive rotation direction) which is opposite to the rotation direction X2. The feed amount (positive rotation) of the tray 8 in step S12 is set to be the same as the feed amount (reverse rotation) of the tray 8 in step S10, and the tray 8A stopped at the component delivery position A3 is as shown in FIG. Figure 8C As shown, it returns to the component detection position A4 and stops.

[0125] As in the first embodiment, by returning the tray 8A to the component detection position A4, production can be restarted from the original state at the time of component insertion error, and the production schedule prepared in advance can be continued.

[0126] When step S12 is executed, the control unit 18 executes step S1 again.

[0127] As described above, in the second embodiment, when a component is inserted incorrectly, the tray 8A is fed to the component delivery position A3 instead of the tray access position A2, and the component 2 on the tray 8A is taken out by the mobile placement head 20 and discarded to the discard unit 102. The operator does not need to manually remove the component 2 on the tray 8A, and the component 2 can be discarded only by the automatic operation of the component mounting device 100. As a result, the time taken for the recovery operation of the component insertion error can be further shortened, and the operation rate of the component mounting device 1 can be improved.

[0128] According to the component mounting apparatus 100 and the method for manufacturing a component mounting substrate of the second embodiment, the predetermined position where the tray 8A is moved and stopped when a component is inserted incorrectly is the component transfer position A3. With such a structure and method, it is possible to handle the problem of the mounting unit 6 taking the component 2 from the tray 8A.

[0129] According to the component mounting apparatus 100 and the method for manufacturing a component mounted substrate of Embodiment 2, the control unit 18 controls the mounting unit 6 to take the component 2 from the tray 8A stopped at the component delivery position A3. According to this structure and method, the mounting unit 6 can automatically take the component 2 from the tray 8A.

[0130] In addition, the component mounting device 100 and the method for manufacturing a component mounting substrate according to the second embodiment further include a discarding unit 102 for discarding at least a portion of the component 2 held by the mounting unit 6. The control unit 18 controls the mounting unit 6 to discard the component 2 taken out from the tray 8A to the discarding unit 102. According to such a structure and method, the component 2 taken out from the tray 8A can be automatically discarded.

[0131] The present invention has been described above by enumerating the above-mentioned embodiments 1 and 2, but the present invention is not limited to the above-mentioned embodiments 1 and 2. For example, in embodiments 1 and 2, the case where the tray 8A moved to the specified position is returned to the component detection position A4 is described, but it is not limited to this case. For example, the tray 8A may be returned to a position offset by several pitches from the component detection position A4 in the rotation direction X2, and then the tray 8 may be returned to the component detection position A4 while the tray 8 is intermittently rotated in the rotation direction X1 according to the production schedule. In other words, the tray 8A moved to the specified position is moved "towards" the component detection position A4 which is the original position.

[0132] In the second embodiment, in step S11, the case where the component 2 is taken out from the tray 8A by the mobile placement head 20 and discarded to the discard unit 102 is described, but the present invention is not limited to this case. It is assumed that the mobile placement head 20 fails to obtain the component 2 based on the posture and shape of the component 2 held on the tray 8A. In this case, the failure of the mobile placement head 20 to obtain the component 2 may be detected, and based on the detection, the tray 8A is moved to the tray access position A2 in the same manner as in the first embodiment, and the operator manually takes the component 2 on the tray 8A. Alternatively, the operation of the component mounting device 100 may be stopped based on the detection of the failure of the mobile placement head 20 to obtain the component.

[0133] The present disclosure fully describes the preferred embodiments with reference to the accompanying drawings, but it is obvious for those skilled in the art to make various deformations and modifications. Such deformations or modifications should be understood to be included therein as long as they do not depart from the scope of the present disclosure based on the attached technical solutions. In addition, the combination of elements of each embodiment and the change of order can be realized without departing from the scope and concept of the present disclosure.
