However, as shown in FIG. 12, the running surface 63 is not exposed when the carrier tape 90 is set in the tape cassette 26. Therefore, in the tape cassette 26 according to the comparative example, the height of the running surface 63 cannot be obtained in a state where the carrier tape 90 is set in the tape cassette 26.

  On the other hand, in the tape cassette 26 according to the present embodiment, apart from the traveling surface 63, a measuring surface 65 that protrudes outward from the traveling surface 63 is specially provided. Then, the height of the measurement surface 65 is measured by the height measuring unit 36. Therefore, even when the carrier tape 90 is set in the tape cassette 26, the height of the running surface 63 can be obtained.

[Description of operation]
Next, the operation of the mounting apparatus 100 will be described. FIG. 13 is a flowchart showing the operation of the mounting apparatus 100. FIG. 14 is a diagram illustrating a relationship between the height H1 of the measurement surface 65 (= the height of the traveling surface 63) and the target height H2 of the lowering of the suction nozzle 35.

  First, the control unit 3 moves the mounting head 30 onto the supply unit 25 by the head moving mechanism 40, and the height measuring unit 36 attached to the mounting head 30 and the measurement surface 65 of a certain tape cassette 26. Are aligned in the horizontal direction (step 101). When the alignment is completed, the control unit 3 measures the height H1 of the measurement surface 65 (the height of the running surface 63) H1 with respect to the reference position by the height measurement unit 36 (step 102).

  In the height measurement, the height H1 of the measurement surface 65 with respect to the reference position can be directly measured or indirectly measured depending on the sensor method employed in the height measuring unit 36. it can. When indirectly measuring the height H1 of the measurement surface 65, the height measurement unit 36 measures the distance between the height measurement unit 36 and the measurement surface 65, and based on this distance, the measurement surface 65 is measured with respect to the reference position. Height H1 is calculated.

  In the present embodiment, the measurement surface 65 is formed on the same plane as the travel surface 63, and the measurement surface 65 is disposed at a position corresponding to the supply window 27. Can be obtained.

  When the height H1 of the measurement surface 65 is measured, the control unit 3 then determines the target height H2 for lowering the suction nozzle 35 based on the height of the measurement surface 65 (height of the traveling surface 63) H1. Is calculated (step 103). The target height H2 of the lowering of the suction nozzle 35 is set such that the thickness T1 of the carrier tape 90 in the portion of the groove 92 that houses the electronic component 2 and the thickness T2 of the electronic component 2 are the height of the measurement surface 65 (the running surface 63 The height can be calculated by adding to H1.

  In the present embodiment, as described above, since the height of the running surface 63 can be accurately measured, the accurate lowering target height H2 can be calculated.

  The value of the thickness (portion 92) T1 of the carrier tape 90 and the thickness T2 of the electronic component 2 are typically different for each tape cassette 26. Accordingly, the relationship between the tape cassette 26 and the combined value of T1 and T2 is stored in the storage unit 4 in advance. When calculating the target height H2 of the lowering of the suction nozzle 35, the control unit 3 reads the combined value of the values of T1 and T2 corresponding to the tape cassette 26 from the storage unit 4, and measures the read combined value. Add to the height H1 of the surface 65.

  After calculating the target height H2 for lowering the suction nozzle 35, the control unit 3 associates the calculated value with the tape cassette 26 and stores it in the storage unit 4 (step 104). Next, the control unit 3 determines whether or not the measurement of the height H1 of the measurement surface 65 has been completed for all the tape cassettes 26 (step 105). When the tape cassette 26 for which the height of the measurement surface 65 is to be measured remains (NO in step 105), the control unit 3 returns to step 101, and the head moving mechanism 40 causes the height measurement unit 36 and the tape to be measured. The measurement surface 65 of the cassette 26 is aligned in the horizontal direction.

  Then, the control unit 3 measures the height H1 of the measurement surface 65 in the tape cassette 26, and calculates the target height H2 of the suction nozzle 35 in the tape cassette 26. Then, the control unit 3 stores the calculated value in the storage unit 4 in association with the tape cassette 26.

  There is no particular limitation on the order in which the height of the measurement surface 65 is measured, but typically the height is measured in order from the measurement surface 65 of the tape cassette 26 located at the end. .

  When the measurement of the height of the measurement surface 65 is completed for all the tape cassettes 26 (YES in step 105), the control unit 3 shifts to normal substrate production (step 106). That is, in this embodiment, since the height of the running surface 63 can be obtained even when the carrier tape 90 is set in the tape cassette 26, the lowering target height of the suction nozzle 35 in each tape cassette 26. Immediately after obtaining the height H2, it is possible to shift to normal substrate production.

  In a normal board production operation, first, the board 1 to be mounted is carried in by the carrying unit 15 and the board 1 is carried to the mounting position. When the substrate 1 is transported to the mounting position, the backup plate 21 is moved upward by the plate lifting mechanism 23 of the backup unit. Thereby, the board | substrate 1 is pinched | interposed between the support pin 22 of the backup part 20, and the upper end part of the guide 16, and the position of the board | substrate 1 is fixed.

  Next, the mounting head 30 is moved in the horizontal direction by the head moving mechanism 40, and the mounting head 30 is moved onto the supply unit 25. Then, the position of the suction nozzle 35 located at the operation position and the position of the supply window 27 of the tape cassette 26 in which the electronic component 2 to be sucked is accommodated by the suction nozzle 35 are aligned in the horizontal direction.

  Then, the downward movement of the suction nozzle 35 located at the operation position is started, and when the suction nozzle 35 reaches the target height H2, the downward movement of the suction nozzle 35 is stopped. Next, the suction nozzle 35 is switched to negative pressure by the air compressor 37. As a result, the electronic component 2 is sucked to the tip of the suction nozzle 35. In the present embodiment, as described above, since the accurate target height H2 can be obtained, the suction rate of the electronic component 2 by the suction nozzle 35 can be improved. When the electronic component 2 is sucked, the suction nozzle 35 that sucks the electronic component 2 is moved upward.

  When the electronic component 2 is taken out from the carrier tape 90 by the suction nozzle 35, the sprocket 52 of the tape cassette 26 is rotated by a predetermined rotation amount. Thereby, the carrier tape 90 is sent out by step feed, and the electronic component 2 is newly supplied to the position of the supply window 27.

  Next, the turret 34 is rotated, and the suction nozzle 35 located at the operation position is switched. When the type of the electronic component 2 sucked by the suction nozzle 35 located at the operation position is different from the type of the electronic component 2 to be picked up by the suction nozzle 35 newly positioned at the operation position, The tape cassette 26 for supplying the electronic component 2 is different. Therefore, in this case, the mounting head 30 is moved in the horizontal direction by the head moving mechanism 40, and the position of the suction nozzle 35 and the position of the supply window 27 that are newly positioned at the operation position are again in the horizontal direction. Is aligned with. Note that the type of the electronic component 2 sucked by the suction nozzle 35 previously located at the operation position is the same as the type of the electronic component 2 to be picked up by the suction nozzle 35 newly positioned at the operation position. In this case, it is not necessary to move the mounting head 30 in the horizontal direction.

  Next, the downward movement of the suction nozzle 35 newly positioned at the operation position is started, and when the suction nozzle 35 reaches the target height H2, the downward movement of the suction nozzle 35 is stopped. Is done. Then, the electronic component 2 is sucked to the tip of the suction nozzle 35. When the tape cassette 26 is different from the previous one (when the supply window 27 is different from the previous one), the target height H2 of the lowering of the suction nozzle 35 is typically different from the previous one. However, in this embodiment, since the accurate target height H2 of the lowering of the suction nozzle 35 is acquired for each tape cassette 26, the electronic component 2 can be sucked accurately in any tape cassette 26. Can do.

  When the electronic component 2 is attracted to each suction nozzle 35, the mounting head 30 is moved from the supply unit 25 onto the substrate 1 by the head moving mechanism 40. Then, the position of the suction nozzle 35 positioned at the operation position and the position on the substrate 1 on which the electronic component 2 is mounted are aligned.

  When the position of the suction nozzle 35 and the position on the substrate 1 are aligned, the suction nozzle 35 is moved downward. The suction nozzle 35 is switched from negative pressure to positive pressure by the air compressor 37. Thereby, the electronic component 2 is detached from the suction nozzle 35 and the electronic component 2 is mounted on the substrate 1.

  Next, the turret 34 is rotated, and the suction nozzle 35 located at the operation position is switched. Next, when the head moving mechanism 40 is driven, the position of the suction nozzle 35 newly positioned at the operation position and the position on the substrate 1 on which the electronic component 2 sucked by the suction nozzle 35 is to be mounted. Are aligned. When the alignment is completed, the suction nozzle 35 is moved downward, and the electronic component 2 sucked at the tip of the suction nozzle 35 is mounted on the substrate 1.

  When all the electronic components 2 sucked by the suction nozzle 35 are mounted on the substrate 1, the mounting head 30 is moved again from the substrate 1 onto the supply unit 25. Then, the electronic component 2 is again picked up by the suction nozzle 35 in the supply unit 25, and the electronic component 2 sucked by the suction nozzle 35 is mounted on the substrate 1. By repeating the adsorption process and the mounting process a plurality of times, the mounting of the electronic component 2 on one board 1 is completed. When the mounting of the electronic component 2 is completed, the fixed state of the substrate 1 by the backup unit is released, and then the substrate 1 is discharged by the transport unit 15.

[Action etc.]
As described above, in the present embodiment, the measurement surface 65 that protrudes outward from the travel surface 63 is specially provided separately from the travel surface 63, and the height of the measurement surface 65 is the height measurement unit. 36. Therefore, even when the carrier tape 90 is set in the tape cassette 26, the height of the running surface 63 can be obtained.

  Furthermore, in this embodiment, the measurement surface 65 is formed on the same plane as the travel surface 63, and the measurement surface 65 is disposed at a position corresponding to the supply window 27, so that the height of the travel surface 63 is increased. Can be measured accurately. As a result, the accurate lowering target height of the suction nozzle 35 can be calculated. As a result, the suction rate of the electronic component 2 by the suction nozzle 35 can be improved. In particular, the present embodiment can accurately adsorb the electronic component 2 even if it is a small component.

  Here, conventionally, in order to attract the electronic component 2 accurately in each tape cassette 26, it is necessary that the tape cassettes 26 have the same height, and accurate accuracy in the height direction is required. It had been. On the other hand, in this embodiment, since the target height H2 of the lowering of the suction nozzle 35 is calculated for each tape cassette 26, it is not necessary for each tape cassette 26 to be exactly the same height. Thereby, the cost of the member (or exchange cart) for mounting each tape cassette 26 included in the mounting apparatus 100 can be reduced.

[Timing for measuring the height of the measurement surface 65]
Next, the timing for measuring the height of the measurement surface 65 will be described. Hereinafter, this timing will be described using three patterns as an example.

“First form of measurement timing”
After normal board production is started, a specific tape cassette 26 is removed from the mounting apparatus 100 (or exchange cart), and another tape cassette 26 is placed where the tape cassette 26 is set. It may be newly attached. For example, when all the electronic components 2 stored in the carrier tape 90 of the tape cassette 26 are used and the carrier tape 90 becomes empty, the tape cassette 26 is replaced. Further, when some trouble occurs in the tape cassette 26 and the electronic component 2 cannot be normally supplied, the tape cassette 26 is replaced.

  In such a case, the height of the running surface 63 of the newly installed tape cassette 26 may be different from the height of the running surface 63 of the original tape cassette 26.

  Therefore, in the first embodiment, the control unit 3 detects the attachment / detachment of the tape cassette 26, and measures the height of the measurement surface 65 by the height measurement unit 36 at the timing when the attachment / detachment is detected. Accordingly, the height of the measurement surface 65 of the tape cassette 26 can be automatically measured at an appropriate timing.

  Specifically, the control unit 3 determines whether or not the connector 61 of the tape cassette 26 has been removed from the connector of the mounting apparatus 100 (or the connector of the exchange truck). When the connector 61 is removed, the control unit 3 determines whether the connector 61 of the tape cassette 26 is connected to the connector of the mounting apparatus 100 (or the connector of the exchange truck).

  When the connector 61 is connected, the control unit 3 specifies the location of the tape cassette 26 that has been attached or detached based on the location of the connector 61 that has been attached or detached. Then, the control unit 3 moves the height measuring unit 36 in the horizontal direction by the head moving mechanism 40 and aligns the height measuring unit 36 and the position of the measurement surface 65 of the tape cassette 26 in the horizontal direction.

  When the alignment is completed, the control unit 3 measures the height H1 of the measurement surface 65 (the height of the traveling surface 63) H1 by the height measuring unit 36, and the height of the measurement surface 65 (the height of the traveling surface 63). Based on H1, a target height H2 for lowering the suction nozzle 35 is calculated. The calculated value is stored in the storage unit 4 in association with the tape cassette 26. When the electronic component 2 is taken out from the tape cassette 26, the target height position H2 unique to the tape cassette 26 is used.

  The controller 3 may measure the height H1 of the measurement surface 65 immediately after the connector 61 is connected. When the electronic component 2 is being mounted, the control unit 3 measures the height H1 of the measurement surface 65 in accordance with the discharge / carry-in timing of the substrate 1 after the connector 61 is connected. You may go.

“Second form of measurement timing”
In the case where the mounting apparatus 100 has an exchange carriage, the exchange carriage in which a plurality of tape cassettes 26 are set may be exchanged together with the exchange carriage. For example, the operator prepares an exchanging carriage in which a plurality of tape cassettes 26 corresponding to the type of the substrate 1 is set outside the mounting apparatus 100 while the mounting apparatus 100 is in operation. Then, when the type of the substrate 1 is changed, the operator replaces the exchange cart with the exchange cart.

  In such a case, the height of the running surface 63 of each tape cassette 26 set on the newly installed exchange cart is the height of the running surface 63 of each tape cassette 26 set on the original exchange cart. Likely different.

  Therefore, in the second embodiment, the control unit 3 detects the attachment / detachment of the replacement carriage (supporting base) to / from the mounting apparatus 100, and the height measurement unit 36 increases the height of the measurement surface 65 at the timing when the attachment / detachment is detected. taking measurement. Accordingly, the height of the measurement surface 65 of the tape cassette 26 can be automatically measured at an appropriate timing.

  Specifically, the control unit 3 determines whether or not the connector 61 of the exchange truck has been removed from the connector 61 of the mounting apparatus 100. When the connector 61 is removed, the control unit 3 determines whether the connector 61 of the exchange truck is connected to the connector 61 of the mounting apparatus 100. When the connector 61 is connected, the control unit 3 measures the height of the measurement surface 65 of each tape cassette 26 set on the newly installed exchange carriage. The processing for measuring the measurement surface 65 and the subsequent processing are the same as the processing described with reference to FIG.

“Third form of measurement timing”
For example, the position of the running surface 63 may change over time due to the influence of vibration or the influence of deformation due to heat.

  Therefore, in the third embodiment, the control unit 3 measures the height of the measurement surface 65 by the height measurement unit 36 at predetermined time intervals. Accordingly, the height of the measurement surface 65 of the tape cassette 26 can be automatically measured at an appropriate timing.

  Specifically, the control unit 3 counts how much time has elapsed since the previous measurement of the measurement surface 65 by a timer. When the counted time reaches a predetermined time, the control unit 3 measures the height of the measurement surface 65 of each tape cassette 26. The predetermined time is typically about 4 to 5 hours, but is not particularly limited.

  The control unit 3 may measure the height H1 of the measurement surface 65 immediately after the predetermined time has elapsed, or when the electronic component 2 is being mounted, after the predetermined time has elapsed, The height H1 of the measurement surface 65 may be measured in accordance with the discharge / carry-in timing of the substrate 1.

  The processing for measuring the measurement surface 65 and the subsequent processing are the same as the processing described with reference to FIG.

[Variations]
In the above description, the case where the measurement surface 65 is provided at the same height as the traveling surface 63 has been described. By setting the measurement surface 65 to such a height, as described above, the height of the traveling surface 63 can be accurately measured. However, the measurement surface 65 does not necessarily have to be provided at the same height as the traveling surface 63. In this case, the height of the traveling surface 63 may be obtained from the difference in height between the measurement surface 65 and the traveling surface 63.

  In the above description, the measurement surface 65 has been described as being provided at a position corresponding to the supply window 27 (a supply position of the electronic component 2). However, it is also possible to arrange the measurement surface 65 at a position shifted from the position of the supply window 27.

  In the above description, the case where the height measuring unit 36 is provided in the mounting head 30 and the height measuring unit 36 moves together with the mounting head 30 by the head moving mechanism 40 has been described. On the other hand, a dedicated moving mechanism for moving the height measuring unit 36 in the horizontal direction may be provided in the mounting apparatus 100. Since the measurement surfaces 65 of the tape cassettes 26 are arranged so as to be aligned along the X-axis direction, the dedicated movement mechanism of the height measurement unit 36 has the height measurement unit 36 positioned above the measurement surface 65. It is configured to be movable along the X-axis direction.

  Alternatively, the height measuring unit 36 is not limited to a movable form, and may be a form fixed at a predetermined position. In this case, the height measuring portions 36 corresponding to the measurement surfaces 65 of the respective tape cassettes 26 are respectively fixed at positions above the measurement surfaces 65 of the respective tape cassettes 26.

  In the case where the existing head moving mechanism 40 is used as a mechanism for moving the height measuring unit 36, it is not necessary to provide a special mechanism for moving the height measuring unit 36. Only one measuring unit 36 is required. Therefore, when cost is taken into consideration, the form in which the existing head moving mechanism 40 is used as a mechanism for moving the height measuring unit 36 is particularly advantageous.

  In the above description, the suction nozzle 35 has been described as an example of the holding member that holds the electronic component 2 and mounts it on the substrate 1. However, the holding member is not limited to the suction nozzle 35. For example, the holding member may be configured to hold the electronic component 2 by sandwiching the electronic component 2 from both sides. The number of tape cassettes is typically plural, but the present technology can also be applied to a case where the number of tape cassettes is one.
