[0077] When it is determined that the interval between the leads Cl is not within the allowable range, the correction command unit 45 outputs a correction command so that the interval between the leads Cl is corrected by the lead correction tool 1.

[0078] That is, based on the detection data of the detection device 30, the correction command unit 45 outputs a correction command so that the leads Cl of the lead parts C held by the nozzle 50 are pressed against at least one of the first correction unit 3 and the second correction unit 5 in order to correct the spacing of the leads Cl with the lead correction tool 1. Based on the detection data of the detection device 30, the correction command unit 45 controls the amount of movement of the nozzle 50 in the Z-axis direction when pressing the lead parts C against at least one of the first correction unit 3 and the second correction unit 5.

[0079] After the leads Cl of the lead components C are pressed against at least one of the first correcting unit 3 and the second correcting unit 5, the drive control unit 41 controls the mounting head 106 so that the lead components C are mounted on the substrate P.

[0080] [Correction method] 11 is a flowchart showing a method for correcting a lead Cl according to an embodiment. The drive control unit 41 moves the mounting head 106 to the supply position PJa. The drive control unit 41 holds the lead component C by the nozzle 50 at the supply position PJa (step S1).

[0081] The drive control unit 41 moves the nozzle 50 to above the detection device 30. The imaging control unit 42 causes the detection device 30 to capture an image of the lead parts C held by the nozzle 50 (step S2).

[0082] The image processing unit 43 acquires image data of the lead parts C from the detection device 30. The image processing unit 43 calculates the position of each of the multiple leads Cl in the XY plane (step S3).

[0083] The determination unit 44 determines whether or not the position of each of the multiple leads Cl is within an allowable range (step S4).

[0084] FIG. 12 is a diagram showing a schematic diagram of image data of a lead component C according to an embodiment. As shown in FIG. 12, a circle TL is set indicating the allowable range of the position of the lead Cl. The center of the circle TL indicates the target position of the lead Cl. When the tip of the lead Cl is positioned inside the circle TL, the determination unit 44 determines that the position of each of the multiple leads Cl is within the allowable range with respect to the target position. In the example shown in FIG. 12, the position of the lead Clx in the X-axis direction is not within the allowable range. Also, the position of the lead Cly in the Y-axis direction is not within the allowable range.

[0085] In step S4, if it is determined that the position of the lead Cl is within the acceptable range (step S4: Yes), the drive control unit 41 moves the mounting head 106 so that the lead component C held by the nozzle 50 is mounted on the substrate P (step S5).

[0086] 13 is a diagram showing a schematic diagram of a state in which a lead Cl of a lead component C according to an embodiment is inserted into an opening PK of a substrate P. The nozzle 50 holding the body Cb moves downward while moving in the XY plane, thereby inserting the lead Cl into the opening PK of the substrate P. After the lead Cl is inserted into the opening PK of the substrate P, the nozzle 50 releases the lead component C from its hold. As a result, the lead component C is mounted on the substrate P.

[0087] In step S4, if it is determined that the position of the lead Cl is not within the allowable range (step S4: No), the correction command unit 45 outputs a correction command so that the lead Cl is corrected by the lead correction tool 1 (step S6).

[0088] Based on the correction command, the drive control unit 41 moves the mounting head 106 so that the lead component C held by the nozzle 50 is positioned above the lead correction tool 1.

[0089] The correction command unit 45 determines which inclined surface to use for correcting the lead Cl from among the multiple inclined surfaces (2A, 2B, 4) of the lead correction tool 1 based on the position of the lead Cl that is not within the allowable range (step S7).

[0090] For example, when narrowing the spacing between the leads Cl in the X-axis direction, the correction command unit 45 determines to use the inclined surface 2A of the first correction unit 3. When widening the spacing between the leads Cl in the X-axis direction, the correction command unit 45 determines to use the inclined surface 2B of the first correction unit 3. When adjusting the spacing between the leads Cl in the Y-axis direction, the correction command unit 45 determines to use the inclined surface 4 of the second correction unit 5.

[0091] The correction command unit 45 determines the amount of pressing when the lead Cl is pressed against the inclined surface (step S8).

[0092] The pushing amount is the amount of movement (lowering amount) in the Z-axis direction of the nozzle 50 holding the lead component C. The pushing amount is set in advance for each inclined surface (2A, 2B, 4) to be used. The pushing amount may be set for each lead component C.

[0093] The correction command unit 45 may determine the amount of pressing when pressing the lead Cl against the inclined surface based on the amount of deviation between the position of the lead Cl that is not within the allowable range and the target position. When the amount of deviation between the position of the lead Cl calculated by the image processing unit 43 and the target position is large, the amount of pressing may be set to a large value. When the amount of deviation between the position of the lead Cl calculated by the image processing unit 43 and the target position is small, the amount of pressing may be set to a small value.

[0094] The drive control unit 41 starts the correction process of pressing the lead Cl against the inclined surface (step S9).

[0095] The correction process includes a process of lowering the nozzle 50 holding the lead component C with the tip of the lead Cl in contact with the inclined surface.

[0096] Fig. 14 is a perspective view showing a method for correcting a lead Cl according to an embodiment. Fig. 15 is a front view showing a method for correcting a lead Cl according to an embodiment. Figs. 14 and 15 show an operation for narrowing the gap between the leads Cl in the X-axis direction.

[0097] 14 and 15, when narrowing the spacing between the leads Cl in the X-axis direction, the pair of inclined surfaces 2A of the first correcting unit 3 are used. The drive control unit 41 lowers the nozzle 50 holding the lead component C in a state where the tips of the pair of leads Cl are in contact with the pair of inclined surfaces 2A. The drive control unit 41 lowers the nozzle 50 by the pressing amount determined in step S8. When the tips of the pair of leads Cl are in contact with the pair of inclined surfaces 2A, the nozzle 50 holding the lead component C is lowered, thereby narrowing the spacing between the leads Cl in the X-axis direction.

[0098] 15, the lead part C descends with the lower surface of the body Cb in contact with the upper surface of the movable member 12A. The movable member 12A is supported by the elastic member 14A. Therefore, when the lead part C descends, the elastic member 14A is compressed, and the movable member 12A descends together with the lead part C.

[0099] After the lead parts C are lowered and the gap between the leads Cl is narrowed, the drive control unit 41 raises the nozzle 50 holding the lead parts C. The movable member 12A is supported by the elastic member 14A. Therefore, when the lead parts C are raised, the movable member 12A is raised by the elastic force of the elastic member 14A.

[0100] When the nozzle 50 is raised, a phenomenon may occur in which at least a part of the lead Cl is caught on the inclined surface 2A. If a phenomenon occurs in which at least a part of the lead Cl is caught on the inclined surface 2A, the lead component C may not be lifted smoothly. In the embodiment, when the nozzle 50 is raised, the movable member 12A rises so as to lift the lead component C due to the elastic force of the elastic member 14A. As a result, even if a phenomenon occurs in which at least a part of the lead Cl is caught on the inclined surface 2A, the lead component C can be lifted smoothly due to the elastic force of the elastic member 14A.

[0101] Fig. 16 is a front view showing a schematic diagram of a method for correcting the leads Cl according to the embodiment, showing an operation for widening the interval between the leads Cl in the X-axis direction.

[0102] 16, when the spacing between the leads Cl in the X-axis direction is to be increased, the pair of inclined surfaces 2B of the first correcting unit 3 is used. The drive control unit 41 lowers the nozzle 50 holding the lead component C in a state where the tips of the pair of leads Cl are in contact with the pair of inclined surfaces 2B. The drive control unit 41 lowers the nozzle 50 by the pressing amount determined in step S8. The spacing between the leads Cl in the X-axis direction is increased by lowering the nozzle 50 holding the lead component C in a state where the tips of the pair of leads Cl are in contact with the pair of inclined surfaces 2B.

[0103] 16, the lead part C descends with the lower surface of the body Cb in contact with the upper surface of the movable member 12B. The movable member 12B is supported by the elastic member 14B. Therefore, when the lead part C descends, the elastic member 14B is compressed, and the movable member 12B descends together with the lead part C.

[0104] After the lead parts C are lowered and the spacing between the leads Cl is expanded, the drive control unit 41 raises the nozzle 50 holding the lead parts C. The movable member 12B is supported by the elastic member 14B. Therefore, when the lead parts C are raised, the movable member 12B is raised by the elastic force of the elastic member 14B.

[0105] When the nozzle 50 is raised, a phenomenon may occur in which at least a part of the lead Cl gets caught on the inclined surface 2B. In the embodiment, when the nozzle 50 is raised, the movable member 12B rises so as to lift the lead component C due to the elastic force of the elastic member 14B. As a result, even if a phenomenon occurs in which at least a part of the lead Cl gets caught on the inclined surface 2B, the lead component C can be smoothly raised due to the elastic force of the elastic member 14B.

[0106] Fig. 17 is a perspective view showing a method for correcting a lead Cl according to an embodiment. Fig. 18 is a side view showing a method for correcting a lead Cl according to an embodiment. Fig. 19 is a front view showing a method for correcting a lead Cl according to an embodiment. Figs. 17, 18, and 19 show an operation for correcting the spacing of the lead Cl in the Y-axis direction.

[0107] As shown in FIG. 17, FIG. 18, and FIG. 19, when the intervals between the leads Cl in the Y-axis direction are corrected, the inclined surfaces 4 (4A, 4B) of the second correction unit 5 are used. The drive control unit 41 lowers the nozzle 50 holding the lead component C in a state in which the tips of the leads Cl arranged on the -X side are in contact with the inclined surfaces 4 (4A, 4B) of the first convex group 10A and the tips of the leads Cl arranged on the +X side are in contact with the inclined surfaces 4 (4A, 4B) of the second convex group 10B. The drive control unit 41 lowers the nozzle 50 by the pushing amount determined in step S8. The intervals between the leads Cl in the Y-axis direction are corrected by lowering the nozzle 50 holding the lead component C in a state in which the tips of the leads Cl are in contact with the inclined surfaces 4 (4A, 4B).

[0108] For example, when the lead component C is lowered while the pair of leads Cl is in contact with the pair of inclined surfaces 4A, the distance between the pair of leads Cl in the Y-axis direction is narrowed. When the lead component C is lowered while the pair of leads Cl is in contact with the pair of inclined surfaces 4B, the distance between the pair of leads Cl in the Y-axis direction is widened.

[0109] 19, the lead part C descends with the lower surface of the body Cb in contact with the upper surface of the movable member 13. The movable member 13 is supported by the elastic member 17. Therefore, when the lead part C descends, the elastic member 17 is compressed, and the movable member 13 descends together with the lead part C.

[0110] After the lead parts C are lowered and the spacing between the leads Cl in the Y-axis direction is corrected, the drive control unit 41 raises the nozzle 50 holding the lead parts C. The movable member 13 is supported by the elastic member 17. Therefore, when the lead parts C are raised, the movable member 13 is raised by the elastic force of the elastic member 17.

[0111] When the nozzle 50 is raised, a phenomenon may occur in which at least a part of the lead Cl gets caught on the inclined surface 4 (4A, 4B). In the embodiment, when the nozzle 50 is raised, the movable member 13 rises so as to lift the lead component C due to the elastic force of the elastic member 17. As a result, even if a phenomenon occurs in which at least a part of the lead Cl gets caught on the inclined surface 4 (4A, 4B), the lead component C can be smoothly raised due to the elastic force of the elastic member 17.

[0112] In the embodiment, the pressing operation of pressing the lead component C against the inclined surface 4 is performed twice for one lead component C. As described above, the lead component C is lowered while the pair of leads Cl is in contact with the pair of inclined surfaces 4A, thereby narrowing the gap between the pair of leads Cl in the Y-axis direction. The lead component C is lowered while the pair of leads Cl is in contact with the pair of inclined surfaces 4B, thereby widening the gap between the pair of leads Cl in the Y-axis direction. Therefore, after the first pressing operation is performed, the lead component C is raised and shifted by the pitch of the leads Cl in the Y-axis direction, and then the second pressing operation is performed.

[0113] After the correction process is completed, the correction command unit 45 performs imaging of the lead component C by the detection device 30 in order to check whether the correction of the lead Cl has been performed correctly (step S10).

[0114] The image processing unit 43 calculates the position of the lead Cl based on the image data acquired in step S10 (step S11).

[0115] The determining unit 44 determines whether or not the position of the lead Cl is within an allowable range. That is, the determining unit 44 determines whether or not the correction of the lead Cl has been correctly performed (step S12).

[0116] In step S12, if it is determined that the position of the lead Cl is within the allowable range (step S12: Yes), the mounting process of the lead component C is performed (step S5).

[0117] In step S12, if it is determined that the position of the lead Cl is not within the permissible range (step S12: No), the determining unit 44 determines whether or not to retry the correction process (step S13).

[0118] In step S13, if it is determined that the correction process is to be retried (step S13: Yes), the processes from step S6 to step S12 are performed.

[0119] In the embodiment, the number of retries for the correction process is preset. For example, if the number of retries is three, the processes from step S6 to step S12 are repeated until it is determined in step S12 that the position of the lead Cl is within the allowable range within the range of the number of retries.

[0120] If the position of the lead Cl is not determined to be within the allowable range in step S12 (step S12: No) even after the number of retries exceeds three, it is determined in step S13 that the correction process is not to be retried (step S13: No).

[0121] Any lead component C in which the position of the lead Cl has not been corrected to within the tolerance is discarded (step S14).

[0122] [effect] As described above, according to the embodiment, the lead correction tool 1 includes the first correction unit 3 for correcting the intervals between the leads Cl in the X-axis direction and the second correction unit 5 for correcting the intervals between the leads Cl in the Y-axis direction. Therefore, even when the leads Cl are arranged in a matrix on the lead component C, the intervals between the leads Cl in the X-axis direction and the Y-axis direction are corrected. In the embodiment, two leads Cl are arranged in the X-axis direction and five leads Cl are arranged in the Y-axis direction. That is, in the embodiment, the lead component C is a so-called two-column, multiple-row lead type. When the two-column, multiple-row lead type lead component C is mounted on the substrate P, the intervals between the leads Cl in the X-axis direction and the Y-axis direction are properly corrected by the lead correction tool 1.
