The suction nozzle 9 inserted in the nozzle stocker 12 and the suction nozzle 9 currently attached to the mounting head 8 are exchanged by controlling the operation of the XY robot control mechanism 10 and the nozzle control mechanism 11 by the control device 6. It is done automatically (without the need for operator manual work).

  In FIG. 1, a plurality of component supply devices 13 that supply components P to the mounting head 8 are provided side by side in the X-axis direction on both sides of the substrate transport path 4 in the Y-axis direction. The control device 6 controls the operation of each component supply device 13 to supply the component P to the component supply port 13a (FIG. 1) provided at the end of each component supply device 13 on the substrate transport path 4 side.

A component camera 15 is provided. The substrate camera 14 is mainly used to image a substrate mark (not shown) for detecting misalignment provided in the substrate PB positioned by the substrate transport path 4 from above, and the component camera 15 is picked up by the mounting head 8. The captured part P is imaged from below. The field of view of the substrate camera 14 can be changed, and the change control is automatically performed (without requiring manual operation by the operator) by the operation control of the field of view changing mechanism (not shown) by the control device 6. The imaging device control of the board camera 14 and the component camera 15 is performed by the control device 6, and image data obtained by the imaging operation of the board camera 14 and the component camera 15 is sent to the control device 6.

  In this component mounter 1, the control device 6 controls the operation of the board conveyance path 4, and loads the board PB input from the outside of the component mounter 1 into the component mounter 1, and puts the board PB into the working position. After positioning, operation control of the component supply device 13, the XY robot control mechanism 10 and the nozzle control mechanism 11 is performed, and the component P supplied to the component supply port 13a of the component supply device 13 is adsorbed by the suction nozzle 9 and picked up. Then, the picked-up component P is mounted at the target mounting position on the substrate PB. When the component P is sucked by the suction nozzle 9 and when the sucked component P is mounted on the substrate PB, the suction nozzle 9 is lowered with respect to the mounting head 8, and in some cases, the suction nozzle 9 is attached to the mounting head 8. Rotate against. As described above, the component supply device 13, the XY robot 7, the mounting head 8, and the control device 6 perform the component P mounting operation (component mounting operation) on the substrate PB positioned at the operation position by the substrate transport path 4. The work execution part 16 (FIG. 1) to perform is comprised.

  In such a component mounting machine 1, the operation of carrying in and positioning the board PB successively sent from the outside, mounting the part P and carrying it out to the outside is repeated, but the type (type) of the board PB is halfway. If it is changed in (i.e., the model is changed), it is necessary to detect the change and change the setup for changing the model as necessary. For this reason, each board PB is provided with an information code D (FIGS. 1 and 2) in which information such as the type of the board PB (board information) is recorded. A substrate information reading unit 17 (FIG. 2) that reads the substrate information of the substrate PB from the information code D included in the positioned substrate PB, and the substrate information read by the substrate information reading unit 17 as needed. A setup change execution unit for automatically executing a setup change work item for model switching (without requiring manual operation by the operator) or requesting the operator to execute a work item to be performed by the operator It has become. As the work items for the setup change, for example, replacement of the component supply device 13 (that is, replacement of the component P mounted on the substrate PB), replacement of the suction nozzle 9 corresponding to the component P to be replaced, and substrate camera corresponding to the substrate PB There are 14 visual field changes.

  First, the board information reading unit 17 will be described. In FIG. 2, the control device 6 includes a reading position candidate storage unit 21, an imaging target position setting unit 22, an imaging control unit 23, an image recognition determination unit 24, a reading unit 25, and an imaging target position change unit 26. The reading unit 17 includes a reading position candidate storage unit 21, an imaging target position setting unit 22, an imaging control unit 23, an image recognition determination unit 24, a reading unit 25, and an imaging target position changing unit 26 of the control device 6, and an information code D. It is comprised from the board | substrate camera 14 used in order to image. Here, the information code D is provided on the upper surface of the substrate PB so that the image can be recognized by imaging from above with the substrate camera 14. The information code D includes, for example, a barcode that is a one-dimensional information code, a QR code that is a two-dimensional information code, and the like.

  In the component mounting machine 1, a plurality of positions (reading positions) are determined in advance as positions where the information code D provided in the board PB positioned at the work position can be read, and the information code D of each board PB is The substrate PB is positioned at one of the plurality of reading position candidates with the substrate PB positioned at the work position. These reading position candidates are given as coordinates in a coordinate system with the component mounter 1 as a reference.

  For example, as shown in FIG. 3A, when five reading position candidates K1, K2, K3, K4, and K5 are determined for the component mounting machine 1, the information code D of each board PB is the board. In a state where the PB is positioned at the work position, it is provided so as to be positioned at any one of the five reading candidate positions K1, K2, K3, K4, and K5. FIG. 3B shows an example where the information code D is provided so as to be positioned at the reading candidate position K2 in a state where the substrate PB is positioned at the work position, and FIG. This is an example when the information code D is provided so as to be positioned at the reading candidate position K4 while being positioned at the work position. The information code D is provided at the same position on the substrate PB when the substrate PB is of the same type, and is positioned at the same reading position candidate when positioned at the work position. .

  The reading position candidate storage unit 21 of the control device 6 stores the coordinates of the plurality of reading position candidates (for example, the coordinates of the reading candidates K1, K2, K3, K4, and K5), and the imaging target position setting unit 22. When the substrate PB is positioned at the work position, one coordinate is selected from the coordinates of the plurality of reading position candidates stored in the reading position candidate storage unit 21 for the substrate PB, and the selected coordinate is selected. Is set as the imaging target position. The imaging control unit 23 controls the operation of the XY robot 7 and causes the substrate camera 14 to perform imaging of the imaging target position set by the imaging target position setting unit 22.

  The image recognition determination unit 24 performs image recognition of the image at the imaging target position obtained by imaging with the substrate camera 14 and determines whether or not the information code D is included in the image obtained by imaging. Here, when the imaging target position set by the imaging target position setting unit 22 matches the position of the information code D provided on the substrate PB currently positioned at the work position, it is obtained by imaging. The information code D is included in the captured image, and the imaging target position set by the imaging target position setting unit 22 is the information code D provided on the substrate PB positioned at the current work position. When it does not coincide with the position, the information code D is not included in the image obtained by imaging.

  When the image recognition determination unit 24 determines that the information code D is included in the image of the imaging target position obtained by imaging by the substrate camera 14, the reading unit 25 uses the information code D to obtain the substrate. The board information such as the type of PB is read.

  The imaging target position changing unit 26 determines that the image recognition determining unit 24 does not include the information code D in the image of the imaging target position obtained by imaging with the board camera 14. The imaging target position set by is changed. Specifically, the change of the imaging target position is stored in the reading position candidate storage unit 21, and a plurality of coordinates determined as positions where the information code D included in the substrate PB positioned at the work position can be read. This is performed by selecting a new coordinate from among them and setting the newly selected coordinate as a new imaging target position.

  As described above, in the board information reading unit 17, when the information code D is not included in the image of the imaging target position obtained by imaging with the board camera 14, the newly selected coordinates are set as the new imaging target position. Since the imaging target position is imaged again after setting, even if the position of the information code D on the substrate PB before and after the model change is different, the substrate is automatically (without the operator performing another work). Information reading continues.

  Next, the setup change execution unit will be described. In FIG. 2, the control device 6 includes a model switching determination unit 27, a download control unit 28, a manual work item determination unit 29, and a setup change execution control unit 30, and the setup change execution unit is a model of these control devices 6. The switching determination unit 27, the download control unit 28, the manual work item determination unit 29, the setup change execution control unit 30, the above-described board information reading unit 17, and the data storage device 41 provided outside the component mounter 1 (for example, the host In addition to FIG. 2, the computer includes a display 42 (FIG. 2) and an end switch 43 (FIG. 2) provided in the component mounter 1.

  As a result of the substrate information reading unit 17 reading the substrate information from the substrate PB, the model switching determination unit 27 of the control device 6 determines the substrate PB between the substrate PB that has read the previous substrate information and the substrate PB that has read the current substrate information. Based on whether or not the types are the same, it is determined whether or not the model has been switched.

  When the model switching determination unit 27 determines that the model switching has been performed, the download control unit 28 provides detailed data corresponding to the information code D of the board PB after the model switching (that is, the board information read this time), that is, Data of what kind of component P supplied from which component supply device 13 is picked up and mounted at which position on the board PB (hereinafter referred to as “mounting data”), and the steps necessary for model switching The replacement work item data (hereinafter referred to as “switching work item data”) is downloaded from the data storage device 41. Then, the data (mounting data and switching work item data) obtained by this download is associated with the information such as the type of the board PB read from the information code D in the board information reading unit 17 (so-called “link”).

  Here, the detailed data corresponding to each information code D is stored in the data storage device 41 provided separately from the control device 6, but the control device 6 included in the component mounter 1 includes It may be stored in a storage area (not shown).

  When the model switching determination unit 27 determines that the model switching of the board PB has been performed (it is detected that the model switching of the board PB has been performed), the manual operation item determination unit 29 performs data transfer to the download control unit 28. Based on the switching work item data downloaded from the storage device 41, it is determined whether or not there is a work item to be performed manually by the operator among the setup change work items required for model switching.

  Here, as described above, the setup change work items necessary for the model change include replacement of the component supply device 13, replacement of the suction nozzle 9, change of the field of view of the board camera 14, and the like. 13 is a work item to be manually performed by the operator, and changing the visual field of the substrate camera 14 is a work item that can be automatically performed under the control of the control device 6. The replacement of the suction nozzle 9 is a work item that is automatically performed under the control of the control device 6 when the suction nozzle 9 after the model switching is already inserted in the nozzle stocker 12, but the suction nozzle 9 after the model switching is changed. Is an operation item to be manually performed by the operator. Note that the type of the suction nozzle 9 currently inserted into the nozzle stocker 12 is grasped by the control device 6 when the suction nozzle 9 is inserted into the nozzle stocker 12.

  The setup change execution control unit 30 determines that the manual operation item determination unit 29 determines that there is a work item to be performed manually by the operator among the setup change work items necessary for model switching. After the operation of 16 is temporarily stopped, work items to be manually performed by the operator are displayed on the display 42 to notify the operator, and the operator is prompted to perform the work. When the operator performs the work necessary for the model switching work and inputs the end of the work by operating the end switch 43, the operation of the work execution unit 16 is resumed and the remaining work items (automatic Executable work items) are executed automatically. On the other hand, when the manual work item determination unit 29 determines that there is no work item to be manually performed by the operator among the setup change work items necessary for the model switching, the operation of the work execution unit 16 is stopped. Without any change, all the work items required for the model change are automatically executed. As a result, the necessary setup change is completed when the model of the board PB is switched, and the component P can be mounted on the board PB after the model switching.

  Next, the execution procedure of the component mounting operation performed by the component mounter 1 will be described with reference to FIGS. 4, 5, and 6. Here, FIG. 4 is a flowchart of a main routine for component mounting work, and FIGS. 5 and 6 are flowcharts of subroutines in the main routine.

  First, the control device 6 operates the board conveyance path 4 to carry the board PB into the component mounter 1, and positions the board PB at the work position based on the detection information from the board detection sensor 5 (FIG. 4). Step ST1). After the positioning of the substrate PB, the control device 6 controls the operation of the XY robot control mechanism 10 to position the substrate camera 14 above the substrate PB and image the above-described substrate mark provided on the substrate PB. And detecting the displacement of the substrate PB from the reference position by performing image recognition of the substrate mark from the obtained captured image.

  After detecting the displacement of the substrate PB from the reference position, the control device 6 uses the substrate camera 14 (that is, by the substrate information reading unit 17) to read information (substrate information) of the substrate PB positioned at the work position. A substrate information reading process (step ST2 in FIG. 4; subroutine shown in FIG. 5) is performed.

  In the substrate information reading process in step ST2, first, the control device 6 (imaging target position setting unit 22) selects one coordinate from the coordinates of the plurality of reading position candidates stored in the reading position candidate storage unit 21. The selected coordinates are set as the imaging target position (step ST21 in FIG. 5).

  When the imaging target position is set, the control device 6 (imaging control unit 23) controls the operation of the XY robot control mechanism 10 to move the substrate camera 14, and images the imaging target position set in step ST21 to the substrate camera 14. (Step ST22 in FIG. 5). Then, the control device 6 (image recognition determination unit 24) performs image recognition of the image obtained by the imaging of the substrate camera 14 (step ST23 in FIG. 5), and whether or not the information code D is included in the image. A determination is made (step ST24 in FIG. 5).

  In step ST24, when it is determined that the information code D is included in the image obtained in step ST22, the control device 6 (reading unit 25) uses the information code D included in the image as a substrate. After reading the information (step ST25 in FIG. 5), the process returns to the main routine. Thereby, step ST2 is completed. On the other hand, when it is determined in step ST24 that the information code D is not included in the image obtained in step ST22, the control device 6 (imaging target position changing unit 26) newly reads from the reading position candidate storage unit 21. The selected coordinates are set as a new imaging target position, the imaging target position is changed (step ST26 in FIG. 5), and the process returns to step ST22. In this way, by returning to step ST22, imaging of the new imaging target position set in step ST26 is performed again. Therefore, the type of the board PB differs before and after the model change, and the information code D on the board PB is changed. Even if the position is different before and after the model change, the reading of the board information is continued without the operator performing another work.

  When the substrate information reading process of step ST2 is completed, the control device 6 (model switching determination unit 27) identifies the type of the substrate PB based on the information of the substrate PB read in the substrate information reading process (FIG. 4). Step ST3). Then, as a result of identifying the type of the board PB, it is determined whether or not there is a model change between the board PB positioned last time and the board PB positioned this time (step ST4 in FIG. 4). Here, the type of the substrate PB read from the information code D of the previously positioned substrate PB is compared with the type of the substrate PB read from the information code D of the currently positioned substrate PB, and both the substrates PB are the same type. Sometimes it is determined that there is no model change, and when both boards PB are of different types, it is determined that there is a model change. If it is determined in step ST4 that the model has been switched, the process proceeds to a model switching work process (step ST5 in FIG. 4, a subroutine shown in FIG. 6).

  In the model switching work process of step ST5, first, the control device 6 (download control unit 28) downloads mounting data and switching work item data for the model of the board PB after the model switching from the data storage device 41 (FIG. 6). Step ST51 and step ST52). When the switching work item data is downloaded, the control device 6 (manual work item determination unit 29), based on the downloaded switching work item data, is manually operated by the operator among the setup change work items necessary for model switching. It is determined whether there is a work item to be performed (step ST53 in FIG. 6). In step ST53, when the operator determines that there are no work items to be manually performed, the control device 6 (the setup change execution control unit 30) automatically sets all the work items necessary for the setup change. Execute (step ST54 in FIG. 6) and return to the main routine.

On the other hand, when it is determined in step ST53 that there is a work item to be manually performed by the operator, the control device 6 (setup change execution control unit 30) temporarily stops the operation of the component mounting machine 1. (Step ST55 in FIG. 6) The work items that the operator should perform manually are displayed on the display 42 and notified to the operator (step ST56 in FIG. 6), and the operator is prompted to perform the work. When the operator performs an operation and the operator operates the end switch 43 (end operation) (step ST57 in FIG. 6), the operation of the component mounting machine 1 is resumed (step ST58 in FIG. 6), and the rest Are automatically executed (that is, work items that can be automatically executed) (step ST59 in FIG. 6), and the process returns to the main routine.

  When step ST54 or step ST59 ends and the process returns to the main routine, the model switching process in step ST5 ends.

  When it is determined that the model switching process in step ST5 has been completed or no model switching has been performed in step ST4 (step ST5 is skipped at this time), the control device 6 performs a work position in step ST1 based on the downloaded mounting data. The component P is mounted on the substrate PB positioned at (step ST6 in FIG. 4).

  In the mounting operation of the component P on the board PB, first, the control device 6 supplies the component P to the component supply port 13a of the component supply device 13, and moves the mounting head 8 above the component supply port 13a to thereby obtain the suction nozzle. 9 causes the part P to be picked up. Then, the mounting head 8 is moved so that the picked-up component P is positioned immediately above the component camera 15, and the component camera 15 images the component P to perform image recognition (so-called component recognition). A positional deviation (suction deviation) of the component P is detected. Next, the mounting head 8 is moved above the substrate PB, the component P sucked by the suction nozzle 9 is separated on the substrate PB, and the component P is mounted at the target mounting position. When the component P is mounted on the board PB, the control device 6 corrects the positional deviation of the board PB that has already been obtained from the reference position and the positional deviation of the part P detected at the time of component recognition with respect to the suction nozzle 9. Thus, the relative position of the suction nozzle 9 with respect to the substrate PB is corrected.

  When the mounting operation (step ST6) of one component P on the substrate PB is completed, the control device 6 has completed the mounting operation of all the components P to be mounted on the substrate PB currently positioned at the work position. Judgment is made (step ST7 in FIG. 4). As a result, when the mounting work of all the parts P has not been completed, the process returns to step ST6 to mount the parts P that are not yet mounted on the board PB, and when the mounting work of all the parts P has been completed. Then, the board conveyance path 4 is operated to carry the board PB out of the component mounter 1 (step ST8 in FIG. 4). Then, it is determined whether or not the component mounting work for all the planned boards PB has been completed (step ST9 in FIG. 4), and as a result, the component mounting work for all the planned boards PB is completed. If not, the process returns to step ST1 to newly carry in the board PB, and if the parts mounting work for all the planned boards PB has been finished, all the work is finished. .

  In the substrate information reading step (step ST2) after returning from step ST9 to step ST1, the control device 6 (imaging target position setting unit 22) first selects the substrate PB positioned at the work position. As the coordinates to be used, the coordinates selected last with respect to the substrate PB from which the reading unit 25 has read information immediately before (on the previous substrate PB) are used. In this way, since the same type of board PB is normally supplied after the model change, the reading position candidate of the information code D to be selected first is the actual information code D as it is. There is a high possibility of being at the reading position, and the time required for reading the information code D can be shortened to improve the tact time.

As described above, the component mounting machine 1 according to the present embodiment has the board positioning means (board transport path 4) for positioning the board PB at the predetermined work position and the board PB positioned at the work position by the board positioning means. On the other hand, in the apparatus including the work execution unit 16 that executes the mounting work of the component P (work for mounting the component), the model switching detection unit (board information reading unit) that detects whether or not the model of the board PB has been switched. 17 and the model switching determination unit 27) of the control device 6), and when the model switching detecting means detects that the model switching of the substrate PB has been performed, the operator can include the changeover work items necessary for model switching. The judgment means (manual work item judgment unit 29 of the control device 6) for judging whether or not there is a work item to be performed manually, the judgment means If it is determined that there are no work items to be performed manually by the operator among the work items for changeover necessary for the changeover, the changeover required for the model changeover is performed without stopping the operation of the work execution unit 16. It is provided with automatic changeover execution means (changeover execution control unit 30) for automatically executing all the work items.

  In addition, the setup change method in the component mounter 1 according to the present embodiment is such that when it is detected that the model change of the board PB has been made, the operator manually handles the setup change work items necessary for the model change. In the determination step (step ST53) for determining whether or not there is a work item to be performed in the work, among the work items for the setup change necessary for the model change in the determination step, the work item to be performed manually by the operator is included. If it is determined that there is no change, an automatic changeover execution step (step ST54) that automatically executes all of the changeover work items necessary for the model change without stopping the operation of the work execution unit 16 is included. ing.

  As described above, in the component mounter 1 or the component replacement method in the component mounter 1 according to the present embodiment, when it is detected that the model of the board PB has been switched, work items for the component replacement necessary for the model switch are determined. The operator determines whether there is a work item to be manually performed by the operator. If there is no work item to be manually performed by the operator, the model is switched without stopping the operation of the work execution unit 16. All work items necessary for setup change are automatically executed. For this reason, the operation of the work execution unit 16 is not stopped until the operator does not need to perform work manually, and it is possible to prevent a reduction in work efficiency when the setup change is performed.

  Although the embodiments of the present invention have been described so far, the present invention is not limited to those shown in the above-described embodiments. For example, the work items for the setup change necessary for the model change shown in the above-described embodiment are merely examples, and other work items may be targeted.

  In the above-described embodiment, the component mounting apparatus refers to an apparatus that performs a component mounting operation by positioning the substrate PB at a work position, and is not limited to the component mounting machine 1 described above. A screen printing machine that performs screen printing, an adhesive application machine that applies an adhesive to the substrate PB, an appearance inspection machine that performs an appearance inspection of the substrate PB, and the like are also included.

  Provided are a component mounting apparatus and a setup change method in the component mounting apparatus that can prevent a reduction in work efficiency when the model is switched.
