A pump driving unit 37 that turns on and off the vacuum pump is connected to an imaging unit 38 that controls imaging by the board recognition camera 25 and the component recognition camera 26.

  Next, referring to the flowchart of FIG. 3, the feeder installation example of FIG. 4, the feeder rearrangement pattern of FIGS. 5 and 6, and the feeder rearrangement guidance display example of FIG. explain. The control device 9 displays the component information of the components to be mounted on the board PB to be mounted, the feeder information of the feeder 17 storing the corresponding components, etc. on the display device 92 so that the operator can visually recognize the plurality of feeders 17. Each is mounted in a plurality of mounting slots 18a (step 1, corresponding to the “storage portion holding step” of the present invention). At this time, the operator may mount the plurality of feeders 17 in the plurality of mounting slots 18a in a freely arranged manner, so that the work time for mounting the feeders can be performed in a short time.

  For example, when the component types of the components to be mounted on the board PB to be mounted are A, B, C, and D, the operator can use the feeders 17A, 17B, and 17C in which the component types A, B, C, and D are stored. , 17D are mounted in a plurality of mounting slots 18a1 to 18a5 (five in this example) in a free arrangement. In this example, it is assumed that the feeder 17D is installed in the installation slot 18a1, the feeder 17A is installed in the installation slot 18a3, the feeder 17C is installed in the installation slot 18a4, and the feeder 17B is installed in the installation slot 18a5, and the installation slot 18a2 is an empty slot (FIG. )reference).

  The control device 9 arranges the substrate PB when mounting each component of a plurality of component types on the single substrate PB to be mounted positioned at the mounting position, and the current arrangement mounted in the plurality of mounting slots 18a. The first movement time of the component picking head 23 with the plurality of feeders 17 in order is calculated (steps 2 and 3, “first movement related amount calculating step, first movement related amount calculating means of the present invention”). ”). The component picking head 23 repeats the operation of moving from the component extracting portion 17b of the feeder 17 to the component mounting position on the board PB via the component recognition camera 26 and then moving to the component extracting portion 17b of the next feeder 17. Therefore, in the following description, for the sake of convenience, the above-described movement time is calculated as the first movement time, and other movement times such as the return position of the component sampling head 23 are not considered.

  Specifically, the movement path da1, da2 of the component picking head 23 between the component mounting position Pa of the component of component type A on the board PB and the component extraction portion 17bA of the feeder 17A mounted in the mounting slot 18a3. , Da3, and the first moving time Ta1 of the component picking head 23 is obtained by dividing the distance of the obtained moving paths da1, da2, da3 by the moving speed of the component picking head 23. Similarly, the component mounting positions Pb, Pc, and Pd of the component types B, C, and D on the board PB and the component extraction portions 17bB and 17bC of the feeders 17B, 17C, and 17D mounted in the mounting slots 18a5, 18a4, and 18a1, respectively. , 17bD, the first movement times Tb1, Tc1, Td1 of the component picking head 23 are obtained (see FIG. 4A).

  When the calculation of the first movement time of the component picking head 23 with respect to the plurality of feeders 17 is completed (“Yes” in step 3), the control device 9 performs the component operation on one board PB to be mounted positioned at the mounting position. The moving time of the component picking heads 23 when mounting is optimally arranged in order of the plurality of feeders 17, that is, the moving time of the component picking heads 23 in the current order of the feeders 17 is reduced as much as possible. The order of arrangement of the feeders 17 serving as the movement time is calculated (step 4, corresponding to “storage section arrangement order calculation step, storage member arrangement order calculation means” of the present invention).

  Specifically, the movement time of the component picking head 23 from the component mounting position Pa of the component type A component on the board PB to the component extraction portion 17bA of the feeder 17A is shorter than the first movement time Ta1 previously obtained. The mounting slot 18a that becomes the paths da11, da12, and da13, in this case, the mounting slot 18a1 is obtained. Similarly, the movement time of the component picking head 23 from the component mounting positions Pb, Pc, Pd of the component types B, C, D on the substrate PB to the component extraction portions 17bB, 17bC, 17bD of the feeders 17B, 17C, 17D is A mounting slot 18a (in this case, the mounting slots 18a2, 18a3, and 18a4) that is a shorter travel path than the first travel times Tb1, Tc1, and Td1 determined previously is determined. Then, the state in which the feeders 17A, 17B, 17C, and 17D are respectively mounted in the mounting slots 18a1, 18a2, 18a3, and 18a4 is obtained as an ideal arrangement order (see FIG. 4B).

  The control device 9 creates a pattern for rearranging the current arrangement order toward the ideal arrangement order of the plurality of feeders 17 obtained (step 5). Then, it is determined whether or not the second movement time of the component sampling head 23 similar to the first movement time between the substrate PB and the rearranged feeder 17 in each created rearrangement pattern has been calculated ( Step 6) When the second movement time has not been calculated, the second movement time is calculated (Steps 7 and 8, “second movement related amount calculation step, second movement related amount calculation means” of the present invention). Equivalent to

  Specifically, when it is assumed that the feeders 17A, 17B, 17C, and 17D are rearranged in the ideal arrangement order in the respective feeders 17A, 17B, 17C, and 17D in the current arrangement order (see FIG. 5A). Each rearrangement pattern (see FIGS. 5B, 5C, 5D, and 5E) is created, and the first between the substrate PB and the rearranged feeder 17 in each of the created rearrangement patterns. The second moving time of the component picking head 23 similar to the moving time is calculated.

  That is, in the rearrangement pattern (see FIG. 5B) when it is assumed that the feeder 17A is rearranged from the current mounting slot 18a3 to the ideal mounting slot 18a1, the component mounting position Pa of the component type A component on the board PB. And a movement path of the component picking head 23 between the feeder 17A rearranged in the mounting slot 18a1 and the distance of the determined moving path is divided by the moving speed of the component picking head 23. To calculate the second movement time Ta2 of the component sampling head 23. However, in this rearrangement pattern, since the feeder 17D is already installed in the installation slot 18a1 (see FIG. 5A), it is necessary to rearrange the feeder 17A and the feeder 17D alternately. Accordingly, the second movement time td2 of the component picking head 23 when the feeder 17D is rearranged from the current mounting slot 18a1 to the temporary mounting slot 18a3 is calculated in the same manner.

  Next, in the rearrangement pattern (see FIG. 5C) when it is assumed that the feeder 17B is rearranged from the current mounting slot 18a5 to the ideal mounting slot 18a2, the second movement time Tb2 of the component sampling head 23 is the same. To calculate. In this rearrangement pattern, since the mounting slot 18a2 is an empty slot (see FIG. 5A), the feeder 17B is rearranged independently.

  Next, in the rearrangement pattern (see FIG. 5D) when it is assumed that the feeder 17C is rearranged from the current mounting slot 18a4 to the ideal mounting slot 18a3, the second movement time Tc2 of the component sampling head 23 is the same. To calculate. However, in this rearrangement pattern, since the feeder 17A is already installed in the installation slot 18a3 (see FIG. 5A), it is necessary to rearrange the feeder 17C and the feeder 17A alternately. Accordingly, the second movement time ta2 of the component picking head 23 when the feeder 17A is rearranged from the current mounting slot 18a3 to the provisional mounting slot 18a4 is calculated in the same manner.

  Next, the second movement time Td2 of the component picking head 23 is the same in the rearrangement pattern (see FIG. 5E) when it is assumed that the feeder 17D is rearranged from the current mounting slot 18a1 to the ideal mounting slot 18a4. To calculate. However, in this rearrangement pattern, since the feeder 17C is already installed in the installation slot 18a4 (see FIG. 5A), it is necessary to rearrange the feeder 17D and the feeder 17C alternately. Accordingly, the second movement time tc2 of the component picking head 23 when the feeder 17C is rearranged from the current mounting slot 18a4 to the provisional mounting slot 18a1 is similarly calculated.

  When the calculation of the second movement time of the component picking head 23 for the plurality of feeders 17 is completed (“Yes” in step 8), the control device 9 calculates the time difference between the first movement time and the second movement time for the plurality of feeders 17. Are calculated as the movement shortening time of the component sampling head 23 (steps 9 and 10, where steps 9 to 16 correspond to the “rearrangement guidance teaching process, rearrangement guidance display means” of the present invention). When the calculation of the time difference between the first movement time and the second movement time for the plurality of feeders 17 is completed (“Yes” in step 10), the rearrangement pattern of the feeder 17 having the largest time difference is selected (step 11). ). Then, it is determined whether or not each feeder 17 has been rearranged in the ideal arrangement order (step 12). If the feeders 17 have not been rearranged in the ideal arrangement order, the process returns to step 5 to create the rearrangement pattern of the feeder 17 again. Then, the processing after step 5 is repeated.

  Specifically, in the feeders 17A and 17D that are alternately rearranged (see FIG. 5B), the sum of the time differences (Ta1-Ta2) + (Td1-td2) with respect to the feeders 17A, 17D is used as the component sampling head. It is calculated as 23 movement shortening time. In the feeder 17B that is a single rearrangement (see FIG. 5C), the time difference Tb1-Tb2 with respect to the feeder 17B is calculated as the movement shortening time of the component picking head 23. In the feeders 17C and 17A that are alternately rearranged (see FIG. 5D), the sum of time differences (Tc1−Tc2) + (Ta1−ta2) with respect to the feeders 17C and 17A is reduced. Calculate as In the feeders 17D and 17C that are alternately rearranged (see FIG. 5E), the sum of the time differences (Td1−Td2) + (Tc1−tc2) with respect to the feeders 17D and 17C is reduced in the movement time of the component picking head 23. Calculate as

  The obtained time difference becomes smaller in the order of (Ta1-Ta2) + (Td1-td2), Tb1-Tb2, (Tc1-Tc2) + (Ta1-ta2), (Td1-Td2) + (Tc1-tc2), for example. Suppose. At this time, a rearrangement pattern (see FIG. 5B) for alternately rearranging the feeder 17A and the feeder 17D is selected. In this rearrangement pattern, only the feeder 17A is in the ideal arrangement order, and the other feeders 17B, 17C, and 17D are not in the ideal arrangement order. Therefore, it is assumed that the feeders 17B, 17C, and 17D are rearranged in the ideal arrangement order. Each rearrangement pattern (see FIGS. 6A and 6B) is created again.

  That is, when it is assumed that the feeder 17B is rearranged from the current mounting slot 18a5 to the ideal mounting slot 18a2 (see FIG. 6A), the second movement time of the component sampling head 23 is Tb2 that has already been obtained, The time difference between the first movement time and the second movement time is Tb1−Tb2 that has already been obtained. Next, assuming that the feeder 17C is rearranged from the current mounting slot 18a4 to the ideal mounting slot 18a3 (see FIG. 6B), the feeder 17C and the feeder 17D are alternately rearranged, and the component sampling head The second movement time 23 is already calculated Tc2 and Td2, and the time difference between the first movement time and the second movement time is (Tc1−Tc2) + (Td1−Td2). In this example, the rearrangement of the feeder 17D from the current mounting slot 18a3 to the ideal mounting slot 18a4 is the same as the rearrangement of the feeder 17C described above, and is therefore omitted.

  Then, it is assumed that the obtained time difference becomes smaller in the order of, for example, Tb1-Tb2, (Tc1-Tc2) + (Td1-Td2). At this time, a pattern in which the feeder 17B is rearranged from the current mounting slot 18a5 to the ideal mounting slot 18a2 is selected (see FIG. 6A). In this rearrangement pattern, since the feeders 17A and 17B are in the ideal arrangement order and the other feeders 17C and 17D are not in the ideal arrangement order, it is assumed that the feeders 17C and 17D are rearranged in the ideal arrangement order. A rearrangement pattern (see FIG. 6C) is created again.

  That is, when it is assumed that the feeder 17C is rearranged from the current mounting slot 18a4 to the ideal mounting slot 18a3 (see FIG. 6C), the feeder 17C and the feeder 17D are alternately rearranged, and the component sampling head 23 The second movement time is Tc2 and Td2 that have already been obtained, and the time difference between the first movement time and the second movement time is already obtained (Tc1−Tc2) + (Td1−Td2). In this example, the rearrangement of the feeder 17D from the current mounting slot 18a3 to the ideal mounting slot 18a4 is the same as the rearrangement of the feeder 17C, and is therefore omitted. Since all the feeders 17A, 17B, 17C, and 17D are in the ideal order by this rearrangement pattern, the calculation of the second movement time of the component sampling head 23 is finished.

  When the feeders 17 are rearranged in the ideal arrangement order (“Yes” in step 12), the control device 9 displays the rearrangement guidance of the feeders 17 until the feeders 17 reach the ideal arrangement order in the descending order of time difference. 92 are displayed side by side from the top of the screen, and the operator is prompted to rearrange the feeders 17 in order from the top of the screen (step 13).

  Specifically, the rearrangement guidance for the feeders 17A and 17D, which are alternately rearranged, that is, the rearrangement guide for rearranging the feeder 17A from the current mounting slot 18a3 to the ideal mounting slot 18a1, and the feeder 17D for the current mounting slot 18a1. The rearrangement guidance for rearranging from the temporary installation slot 18a3 to the provisional installation slot 18a3 is displayed on the upper part of the display device 92. A rearrangement guide for the feeder 17B, that is, a rearrangement guide for rearranging the feeder 17B from the current mounting slot 18a5 to the ideal mounting slot 18a2 is displayed below the display. Further, the rearrangement guidance of the feeder 17C and the feeder 17D, which are alternately rearranged below the display, that is, the rearrangement guide for rearranging the feeder 17C from the current installation slot 18a4 to the ideal installation slot 18a3 and the feeder 17D A rearrangement guide for rearranging from the mounting slot 18a3 to the ideal mounting slot 18a4 is displayed to prompt the operator to rearrange the feeders 17 in order from the top of the screen. Display items at this time include, for example, a feeder (feeder to be rearranged), a current slot (currently installed slot), a change slot (slot installed), and a shortened time (reordered) The time to be shortened (time difference) is displayed (see FIG. 7A).

  The control device 9 determines whether or not the rearrangement of the feeders 17 having the largest time difference displayed on the upper part of the screen of the display device 92 has been completed (step 14). Whether or not the rearrangement of the feeders 17 has been completed can be determined by receiving an attachment / detachment signal of the feeder 17 transmitted via the connector 18b. When the rearrangement is completed, it is determined whether or not the rearrangement of all the displayed feeders 17 is completed (step 15), and the rearrangement of all the displayed feeders 17 is completed. If not, only the display of the completed rearrangement at the top of the screen of the display device 92 is erased (step 16), and the display of the rearrangement after the rearrangement that has been erased is returned to step 13 and displayed. On the other hand, when the rearrangement of all displayed feeders 17 is completed, all the processes are terminated.

  Specifically, when the alternating rearrangement of the feeder 17A and the feeder 17D is completed, the rearrangement guidance for the feeder 17A and the feeder 17D is deleted, and the rearrangement guidance for the feeder 17B, and the alternate rearrangement guidance for the feeder 17C and the feeder 17D are displayed. The images are displayed in order from the top of the screen of the display device 92 (see FIG. 7B). When the rearrangement of the feeders 17B is completed, the rearrangement guidance for the feeders 17B is deleted, and the alternate rearrangement guidance for the feeders 17C and 17D is displayed on the upper part of the screen of the display device 92 (see FIG. 7C). When the alternating rearrangement of the feeder 17C and the feeder 17D is completed, the alternate rearrangement guidance for the feeder 17C and the feeder 17D is deleted, and all the processes are ended.

  Here, when the rearrangement guidance display operation of the feeder 17 by the control device 9 is started, the mounting of the component to the substrate PB is also started. However, when the suction nozzle 24 collects the component, the component is stored. The feeders 17 being rearranged may be removed from the mounting slot 18a. The operation of the control device 9 in such a case will be described with reference to the flowchart of FIG. 8 (corresponding to “collection change teaching means” of the present invention). When the control device 9 is instructed to mount the component on the board PB (step 21), the control device 9 moves the component picking head 23 to the feeder 17 in which the component is stored (hereinafter referred to as “the current feeder 17”) ( Step 22). Then, it is determined whether or not rearrangement of the current feeder 17 is instructed (step 23). If rearrangement of the current feeder 17 is not instructed, the parts stored in the current feeder 17 are collected. Is mounted on the substrate PB (step 24).

  On the other hand, if the rearrangement of the current feeder 17 is instructed in step 23, the collection of the parts stored in the current feeder 17 is skipped, and whether or not the installation of the part to be mounted next is instructed. Is determined (step 25). If it is instructed to mount a component to be mounted next, the component picking head 23 is moved to the feeder 17 in which the component is stored (hereinafter referred to as “next feeder 17”) (step 22). . Then, it is determined whether or not rearrangement of the next feeder 17 is instructed (step 23). If rearrangement of the next feeder 17 is not instructed, the parts stored in the next feeder 17 are collected. Is mounted on the substrate PB (step 24).

  Then, after picking up the components in step 24 and mounting them on the board PB, or in step 25, when the mounting of the next component to be mounted is not instructed, the rearrangement of the current feeder 17 is instructed and sampling is performed. The presence / absence of a disabled part is determined (step 26). If there is a part that cannot be picked up, the process returns to step 22 to execute the above-described processing. On the other hand, if there is no part that cannot be collected, it is determined whether or not all parts have been mounted (step 27). If all parts have not been mounted, the process goes to step 21. Returning to the above-described process, if all the components have been mounted, all the processes are terminated.

  In the rearrangement guidance display operation of the feeder 17 by the control device 9 described above, the case where different parts are sequentially collected by one suction nozzle 24 and mounted on the substrate has been described. However, a plurality of suction nozzles are provided. For example, when the same type of components are continuously collected and mounted on the substrate by a rotary type component collecting head, the rearrangement guidance display of the feeder 17 can be similarly performed, and the moving time of the component collecting head can be shortened. .

  For example, when the component type of the component to be mounted on the board PB to be mounted is A, the operator has a plurality of (eight in this example) mounting slots 17A1, 17A2, and 17A3 each containing the component type A. It mounts | wears with 18a1-18a8 by free arrangement | positioning. In this example, it is assumed that the feeder 17A1 is installed in the installation slot 18a1, the feeder 17A3 is installed in the installation slot 18a3, and the feeder 17A2 is installed in the installation slot 18a7, and the installation slots 18a2, 18a4, 18a5, 18a6, and 18a8 are empty slots (FIG. 9 ( A)). The ideal feeders 17A1, 17A2 and 17A3 are arranged when the feeder 17A1 is installed in the installation slot 18a1, the feeder 17A2 is installed in the installation slot 18a2, the feeder 17A3 is installed in the installation slot 18a3, and the installation slots 18a4 to 18a8 are empty slots. (See FIG. 9B).

  Here, the movement path of the component picking head between the component mounting position Pa of the component type A component on the board PB and the component extraction portion 17bA1 of the feeder 17A1 mounted in the mounting slot 18a1 is the current arrangement order. Since it is the same in the ideal arrangement order, it is omitted. Then, the first movement time of the component picking head in the arrangement order of the current feeders 17A1, 17A2, and 17A3 is the component takeout portion 17bA1 of the feeder 17A1 installed in the installation slot 18a1 and the feeder installed in the installation slot 18a7. The distance f1 of the movement path of the component picking head between the component extraction portion 17bA2 of 17A2 and the components of the feeder 17A3 mounted in the mounting slot 18a3 and the component extraction portion 17bA2 of the feeder 17A2 mounted in the mounting slot 18a7 This is obtained by dividing the sum f1 + f2 of the distance f2 of the movement path of the component picking head with respect to the take-out portion 17bA3 by the moving speed of the component picking head 23.

  On the other hand, the first movement time of the component picking heads in the order in which the ideal feeders 17A1, 17A2, and 17A3 are arranged is the feeder that is mounted in the component takeout portion 17bA1 and the mounting slot 18a2 of the feeder 17A1 that is mounted in the mounting slot 18a1. The distance g1 (> f1) of the moving path of the component picking head between the component extracting portion 17bA2 of 17A2 and the component extracting portion 17bA2 and the mounting slot 18a3 of the feeder 17A2 mounted in the mounting slot 18a2. This is obtained by dividing the sum g1 + g2 of the distance g2 (> f2) of the movement path of the part picking head between the part picking part 17bA3 of the feeder 17A3 and the moving speed of the part picking head 23. Therefore, in this case, it is possible to shorten by the time obtained by dividing the moving distance difference (f1−g1) + (f2−g2) of the component picking head by the moving speed of the component picking head 23.

  As described above, according to the component mounting apparatus 1 of the present embodiment, the control device 9 moves the component sampling head 23 in the current order of feeders 17 and the order of feeders 17 after rearrangement. The time difference or distance difference is displayed on the display device 92 in descending order. For this reason, the operator rearranges the feeders 17 according to the guidance display during the operation of the component picking head 23 for mounting the components on the board PB even if the plurality of feeders 17 are set in the plurality of mounting slots 18a in a free arrangement. As a result, the total moving time or total moving distance of the component picking head 23 when producing one board PB can be shortened, and the component picking efficiency can be increased. Therefore, the mounting tact of the component with respect to the board PB can be improved.

  Further, the control device 9 deletes the display of the rearrangement guidance when the rearrangement of the displayed feeders 17 is completed, and raises and displays the subsequent rearrangement guidance. Thereby, the operator can surely recognize the feeders 17 that need to be rearranged. Therefore, it is possible to prevent the occurrence of defective substrates due to the rearrangement of the feeder 17 by mistake. Further, when a command for rearranging the feeders 17 of the parts is issued when the parts are being picked up by the parts picking head 23, the control device 9 delays the picking of the parts and picks up the parts to be picked up next. I am trying to command. Thereby, it is possible to continue the component collection by the component collection head 23 without waiting for completion of rearrangement of the feeders 17. Therefore, the mounting tact of the component with respect to the board PB can be further improved.

  In the above-described embodiment, the rearrangement process of the feeder 17 that shortens the movement time of the component picking head 23 has been described. However, the rearrangement process of the feeder 17 that shortens the movement distance of the component picking head 23 may be used. Further, for example, the first and second movement times are obtained for each of the feeders 17A to 17D in FIG. 5A, but the substrate B is produced with the arrangement for each of the patterns in FIGS. 5A to 5E. It is good also as a structure which calculates | requires the production time of one board | substrate B as 1st and 2nd movement time. That is, when the components are collected in the order of the feeders 17A to 17D and mounted on the substrate B, the components are collected in the order of the feeders 17A to 17D in the arrangement for each of the patterns in FIGS. The total time implemented in B is determined as the first and second travel times.

  Further, the control device 9 is configured to perform the rearrangement processing of the feeders 17. However, the rearrangement processing device may be provided separately from the control device 9, and the rearrangement processing device may perform the rearrangement processing of the feeders 17. . In addition, the rearrangement guidance display is configured to display in descending order of the effect of shortening the movement time (movement distance) of the component picking head 23. For example, the rearrangement guidance display is performed in the order of the mounting slots 18a, and the workers are rearranged in any order. You may comprise as follows. Further, the rearrangement of the feeders 17 is configured to be displayed on the display device 92. However, for example, the rearrangement of the feeders 17 may be configured to be guided and taught by printout or voice.

  Moreover, although the case where the rearrangement guidance of the feeder 17 is displayed has been described, when the parts supply unit is manually rearranged by the operator, the rearrangement guidance needs to be displayed so that the worker can visually recognize the rearrangement guidance. The present invention is also applicable to the case where the tray rearrangement guidance is displayed. Further, although the component mounting apparatus 1 is configured to include the head transfer mechanism that transfers the component sampling head 23, the present invention may be applied to a configuration that includes a substrate transfer mechanism that transfers the substrate PB without the head transfer mechanism. Applicable.
