It is made to be able to recognize that.

  Further, a feeder detection device 206 for detecting whether or not the feeder 20 is attached is attached to the column 220. Each feeder detection device 206 has a photoelectric sensor 222 attached to the upper part of the column 220 corresponding to each of the plurality of slots 180, and communication for outputting information obtained by the photoelectric sensor 222 to the control device 300 described later. Device 224. Each photoelectric sensor 222 extends from the column 220 to the side opposite to the feeder 20 side along the Y-axis direction. As shown in FIG. 3, the photoelectric sensor 222 receives light from the light emitter 226 at a distance in the extending direction. And a body 228. The light emitter 226 emits light (for example, infrared rays) upward. When the feeder 20 is attached, the light is reflected by the lower surface of the feeder body 106, and the reflected light is received by the light receiver. 228. On the other hand, when the feeder 20 is not attached, the light from the light emitter 226 is not reflected, so the light receiver 228 does not detect the light. Therefore, it is possible to detect whether the feeder 20 is attached based on the light receiving state of the photoreceptor. The light emitter 226 is preferably configured to emit light having a wavelength different from that of the LED 210.

  The column 220 is provided with a position detection device 240 that detects a relative position of the first table 22 with respect to the column 220. The position detection device 240 includes a photoelectric sensor 242, and at least one dog (detected portion) 244 is fixed to the first table 22 so as to move integrally. The photoelectric sensor 242 includes a pair of light emitters and light receivers disposed so as to sandwich the movement path of the dog 244 from above and below, and detects that the dog 244 exists between the light emitters and the light receivers. Thus, the relative position between the first table 22 and the column 220 (that is, the work support device 200) is acquired. If the dog 244 is provided at a position corresponding to each of all the slots 180, the current position of the first table 22 can be detected from the change history of the light receiving state of the photoreceptor accompanying the movement of the first table 22. However, in this embodiment, only one dog 244 is provided, and when the dog 244 is positioned between the light emitter and the light receiver of the photoelectric sensor 242, the reference position of the first table 22, that is, The positions corresponding to all the instruction / detection units 208 in all the slots 180 are detected.

The electronic component mounting system is controlled by the control device 300 shown in FIG.
The control device 300 is mainly composed of a computer 310 including a CPU 302, a ROM 304, a RAM 306, and a bus 308 for connecting them. An input interface 312 is connected to the bus 308, and photoelectric sensors 222 and 242 of the work support device 200, an operation panel 314 as an input device, and a barcode reader 316 are connected. Further, an output interface 318 and a servo interface 320 are connected to the bus 308. Various servo motors 24, 38, 60, 76 are connected to the servo interface 320, and the LED 210 and the display device 330 of the work support device 200 are connected to the output interface 318. The ROM 304 stores various programs such as a work support program shown in FIGS. 6 to 7 as well as a control program for controlling the electronic component mounting work.

  The feeder attaching / detaching operation in the electronic component mounting system configured as described above will be described below. In the detaching operation, for example, the first table 22 and the second table 23 are each provided with the feeder 20 holding a group of electronic components necessary for assembling the same type of electronic circuit. And the second table 23 are alternately moved to the component supply area to supply the electronic component, and the electronic component is lost in the feeder 20 of the first or second table 22 or 23, or the electronic component This is done when the remaining amount of is less than the set number. Also, the first table 22 and the second table 23 are each provided with a feeder 20 holding a group of electronic components necessary for assembling different types of electronic circuits. The feeder attaching / detaching operation is also performed when the number of electronic circuits assembled from the electronic parts supplied from either of the two tables 23 reaches a predetermined number.

  First, a case where there is no electronic component held in any one of the feeders 20 or the remaining amount of electronic components is equal to or less than the set number will be described. In the present embodiment, the computer 310 of the control device 300 has a function of determining that there is no electronic component in the feeder 20 when the mounting head 34 cannot receive the electronic component twice from the same feeder 20. Have. Further, the identification code representing the feeder name of each feeder 20 and the quantity of electronic components mounted on the feeder 20 are stored in the RAM 306 of the computer 310 at the start of the mounting operation or when the feeder 20 is replaced and supplied from the feeder 20. By counting the number of the electronic components thus obtained, the remaining amount of the electronic components in each feeder 20 is monitored by the computer 310. Therefore, if there is no electronic component for a certain feeder 20 or if the remaining amount of electronic component falls below a predetermined number (including 0), the control device 300 may instruct that the feeder 20 should be replaced. it can. This instruction includes the feeder name of the feeder 20 to be replaced this time (the feeder name of the feeder 20 to be removed and the feeder 20 to be attached) and the corresponding instruction / detection unit 208 (hereinafter referred to as the target unit 208). The position of is included. Hereinafter, description will be given based on the flowchart shown in FIG.

  If an instruction is issued in step S2 (hereinafter simply referred to as S2; the same applies to other steps), the contents of the instruction are displayed on the display screen of the display device 330 in S3, and are positioned in the current component supply area in S4. The stored table (for example, the first table 22) is retreated to the retreat area, and the second table 23, which is the other table, is moved to the component supply area to supply the parts to the electronic component mounting apparatus. Start.

  Regarding the first table 22 retracted to the retreat area, the position detecting device 240 detects that the first table 22 has reached the work position, and the movement of the first table 22 is stopped. After that, in S5, the first and second light projecting devices 202 and 204 of the target unit 208 corresponding to the feeder 20 that should perform the removal / removal operation this time among the work support devices 200 are turned on in accordance with the previously issued instruction. The feeder 20 to be replaced is shown to the operator. In S6, the flag F1 is set to 1, and thereafter the execution of S2 to S6 is skipped. The operator recognizes the feeder 20 instructed by the work support device 200 by searching for the one where the light of the LED 210 is irradiated on the upper end surface of the input bar 126 among the plurality of feeders 20, and moves the feeder 20 to the feeder 20. While removing from the table 22, the new feeder 20 corresponding to it is attached. When the correct feeder 20 is removed by the operator, a signal indicating that the feeder 20 is not detected is output by the photoelectric sensor 222 of the target unit 208, and based on this, the controller 300 determines in step S7 that the removal operation has been performed correctly. To do. On the other hand, when the operator removes the feeder 20, the through hole 165 of the slot 180 looks bright, so that the removal work is recognized as being correct.

  On the other hand, if the operator removes the feeder 20 different from the feeder 20 to be removed this time, a signal indicating that the feeder 20 is not detected is output by the photoelectric sensor 222 of the instruction / detection unit 208 corresponding to the different feeder 20, and S7. In step S8, it is determined that the removal work is wrong. In step S8, the light projecting devices 202 and 204 of the target unit 208 are blinked to notify the operator of the error.

  In this embodiment, the new feeder 20 is made to wait in a standby place provided outside the system. When attaching the new feeder 20 to the table 22, the operator causes the barcode reader 316 to read the barcode attached to the feeder 20 and then attaches it to the original slot 180. Since the light projecting devices 202 and 204 of the target unit 208 are continuously lit in the slot 180 in which the new feeder 20 is to be installed, even if another slot 180 on the table 20 is free, the operator can be sure that the original A new feeder 20 can be installed in the slot 180 of the first slot. The taped electronic component 100 is mounted on the new feeder 20 in advance, and the barcode of the taped electronic component and the barcode of the feeder 20 are read by the barcode reader when the taped electronic component 100 is attached. It is assumed that it has been entered.

  That is, the supply reel 104 is mounted on each feeder 20 before each feeder 20 is made to wait at the standby place. At this time, the barcode attached to the feeder 20 and the bar attached to the supply reel 104 are mounted. The code is read by the barcode reader 316 or another barcode reader, and the data is supplied to the control device 300. Therefore, the control device 300 knows the feeder name of the feeder 20 to be attached, and can determine whether or not the feeder 20 to be attached is as planned as described above.

  In S9, the control device 300 determines that the feeder to be attached is intended by comparing the barcode read by the barcode reader 316 with the barcode input in advance, and In S11, if it is determined that the new feeder 20 is attached at the correct position based on the signal from the photoelectric sensor 222 of the target unit 208, the first and second light projecting devices 202 and 204 are turned off in S12. The operator is notified that the feeder 20 has been exchanged correctly. This completes one desorption operation.

  On the other hand, if the barcode read by the barcode reader 316 is not scheduled, the determination in S9 is NO, and in S13, the projectors 202 and 204 of the target unit 208 are turned off and attached. The operator is informed that the feeder 20 that is about to be fed is wrong. Therefore, the operator replaces the feeder 20 with another one, reads the barcode with the barcode reader 316 again, and confirms that the light projecting devices 202 and 204 of the target unit 208 are turned on in S10. The feeder 20 can be selected. If the new feeder 20 is not mounted at the correct position, a signal indicating that the feeder 20 is detected is output by the photoelectric sensor 222 of the instruction / detection unit 208 corresponding to the different feeder 20, and the mounting operation is performed in S11. In S8, the light projecting devices 202 and 204 of the target unit 208 are blinked to notify the operator of the error. When the operator re-installs the feeder 20 in the slot 180 where the through hole 165 is brightly illuminated by the light projecting device 204, the light projecting devices 202 and 204 are turned off, and one detachment operation is completed. In this state, the first table 22 is kept in the retreat area until an instruction to replace the second table 23 that is currently supplying electronic components is issued.

  For the feeder 20 that has been removed from the table 22 by the replacement operation, the empty supply reel 104 is replaced with a new supply reel 104, and the cover tape 102 taken up by the take-up reel 124 is removed from the take-up reel 124. Then, the cover tape 102 of the new supply reel 104 is wound around the take-up reel 124 and is made to wait at the standby place.

  In the present embodiment, it is not planned that the two or more feeders 20 be attached / detached at the same time, but it is possible to make it possible. When it becomes necessary to attach or detach two or more feeders 20 at the same time, the light projecting devices 202 and 204 of the target unit 208 corresponding to each of the two or more feeders 20 are sequentially turned on. Can be sequentially replaced with a new feeder 20 in accordance with the instruction. In that case, it is desirable to turn off all the light projecting devices 202 and 204 when the instructed removal / replacement (replacement) work of all the feeders 20 is completed. However, this is not indispensable, and when an instruction to perform the detaching operation for two or more feeders 20 is issued at the same time, the instruction / detection unit 208 corresponding to all of the two or more feeders 20 is loaded. The optical devices 202 and 204 are turned on at the same time, and the operator arbitrarily determines the order and inputs the number of the slot 180 to which the feeder 20 is to be installed next from the operation panel 314. It is also possible to read the code.

Next, a feeder attaching / detaching operation when the number of assembled electronic circuits reaches a predetermined number and it is necessary to change the setup for assembling another electronic circuit will be described based on the flowchart shown in FIG.
The control device 300 detects that the number of electronic circuits that have been assembled so far has reached the predetermined number, and it is necessary to change the setup in either the first or second table 22 or 23, and in S102, this is indicated. If an instruction is issued, in S103, the operator is notified that the setup change is necessary by displaying it on the display screen of the display device 330, and in S104, the table (first table) that has been in the parts supply area until then is displayed. 22) is saved in the save area, while the table that has been in the save area (here, the second table 23) is moved to the component supply area.

  At the time of the setup change work, the instruction / detection unit 208 instructs one of the plurality of feeders on the first table 22 that requires replacement (detachment). Although all the feeders 20 may be removed once at the time of the setup change, in this embodiment, in order to shorten the time required for the setup change work as much as possible, the removal work of the feeder 20 that does not need to be replaced is performed. It is designed to be omitted. A control program for the electronic circuit to be assembled next is sent from the host computer to the control device 300, and the control program includes the electronic components to be supplied from the positions of the slots 180 on the first table 22. A parts list representing the name is included. The control device 300 compares the parts list for the new electronic circuit with the parts list corresponding to the feeder 20 that is actually mounted on the first table 22, and does not need to be replaced with the feeder 20 that needs to be replaced. The feeder 20 is discriminated, and the attachment / detachment work is instructed only for the feeder 20 that needs to be replaced.

  It is also possible to sequentially turn on the light projecting devices 202 and 204 of the instruction / detection unit 208 corresponding to each one of the plurality of feeders 20 that need to be detached and attached during the setup change work. However, in this embodiment, in S105, the light projecting devices 202 and 204 of the instruction / detection unit 208 corresponding to all of the feeders 20 are turned on all at once, and the operator can arbitrarily set the order of the feeders 20 to be attached and detached. To be able to decide. In S105, F2 is set to 1, and the execution of S101 to S105 is skipped thereafter. In S106, the number of the slot 180 that the operator inputs from the operation panel 314 to perform the next detaching operation is acquired, and if the feeder 20 of the slot 180 is removed, the signal of the feeder detection device 206 is displayed in S107. Based on this, the control device 300 determines that the correct feeder 20 has been removed. In this case, since the light projecting devices 202 and 204 of the instruction / detection unit 208 are kept lit, the operator can confirm that the removal work he / she performed is correct. On the other hand, if the feeder 20 is removed from the slot 180 having a different number, the determination in S107 is NO, and the process proceeds to S108, in which the instruction / detection unit 208 corresponding to the slot 180 from which the feeder 20 was mistakenly removed is thrown. The optical devices 202 and 204 are blinked. As a result, if the operator notices that the wrong feeder 20 has been removed and the correct feeder 20 has been removed, the determination in S107 becomes YES, and the process proceeds to S109.

  After removing the feeder 20, the operator causes the barcode reader 316 to read the barcode of the feeder 20 to be exchanged with the feeder 20. The read barcode is acquired, and in S109, the control device 300 determines whether or not the barcode read by the barcode reader 316 is a scheduled one. If the barcode is scheduled, the corresponding light projecting devices 202 and 204 are kept lit, so that the operator can recognize that the feeder 20 to be attached is correct. If the operator installs the correct feeder 20 in the correct slot 180, the control device 300 detects the fact in S110 based on the signal from the feeder detection device 206, and proceeds to S111 to correspond to the slot 180. The light projecting devices 202 and 204 of the instruction / detection unit 208 are turned off. Therefore, the operator can confirm that the attachment / detachment work he / she performed is correct. On the other hand, if at least one of the bar code and the slot 180 is different from the scheduled one, the control device 300 proceeds to S108 and the instruction / detection unit 208 corresponding to the slot 180 to which the feeder is attached. The light projecting devices 202 and 204 are blinked. Therefore, the operator can recognize that he / she has installed the feeder 20 at an incorrect position.

  If there is a feeder 20 to be detached in addition to the feeder 20 that has been detached this time, the determination in S112 is NO, and one execution of this program ends. On the other hand, if the detaching operation is completed for all the feeders 20, the determination in S112 is YES, and the process proceeds to S113 to output a signal indicating the end of the current operation, and the flags and the like are returned to the initial values. . In this state, the first table 22 is kept in the retreat area until an instruction to replace the second table 23 that is currently supplying electronic components is issued.

  In the present embodiment, as described above, it is not essential that the feeders 20 to be replaced are removed and attached one by one. First, all the feeders 20 to be removed are removed, and then the slot numbers are removed. In the case where new feeders 20 are attached one by one while inputting the above and reading the barcode, it is possible to support the attaching operation.

  For example, as shown in the flowchart in FIG. 8, first, the same steps as S101 to S105 described above are executed, and then it is monitored in S156 to S160 that all feeders 20 to be replaced this time are correctly removed. Specifically, if the feeder 20 removed this time is one of the feeders 20 to be replaced, the determination in S157 becomes YES, and the target unit 208 corresponding to the slot 180 from which the current feeder 20 was removed in S158. The projectors 202 and 204 are turned off. On the other hand, if the removed feeder 20 is wrong and it is not necessary to remove it, the determination in S157 is NO, and the process proceeds to S166, where the instruction / corresponding to the slot 180 in which the feeder 20 is mistakenly removed this time. The light projecting devices 202 and 204 of the detection unit 280 are blinked. If all the feeders 20 to be replaced are removed, all the target units 208 are turned off, so the determination in S159 is YES, the flag F3 is set to 1 in S160, and the subsequent execution of S157 to S160 is performed. Skipped.

  Next, the slot number input by the operator is recognized in S161, and the light projecting devices 202 and 204 of the target unit 280 corresponding to the slot 180 are turned on in S162. The operator reads the barcode of the feeder 20 to be installed in the slot 180. In S163 and S164, the barcode corresponds to the slot number previously input, and the feeder 20 is installed in the correct position. If it is determined, the process proceeds to S165, and the light projecting devices 202 and 204 of the target unit 280 corresponding to the slot 180 are turned off. On the other hand, if at least one of the barcode and the mounting position is different, the process proceeds to S166, and the light projecting device 202 of the instruction / detection unit 280 corresponding to the slot 180 in which the feeder 20 is erroneously mounted this time. 204 is flashed.

  Next, the process proceeds to S167, where it is determined whether or not the feeders 20 have been installed for all the slots 180. If the feeders 20 to be installed remain, the determination in S167 is NO, and this program is executed once. Execution ends. On the other hand, if all the feeders 20 are installed, the process proceeds to S168, where an end signal indicating that the current work is completed is output, and the flag and the like are set to initial values. This completes one setup change operation. In this state, the first table 22 is kept in the retreat area until an instruction to replace the second table 23 that is currently supplying electronic components is issued.

  As is clear from the above description, in the present embodiment, the first light projecting device 202 constitutes “feeder instruction means”, and the second light projection device 204 constitutes “position instruction means”. Further, in the control device, the part for executing S11 and S12, the part for executing S108, S110 and S111, and the part for executing S164 to S166 constitute an “attachment suitability display device”, and S7 and S8. The part to be executed, the part to execute S107 and S108, and the part to execute S157, S158 and S166 each constitute a “removability appropriateness display device”.

  In the above-described embodiment, the feeder 20 having no electronic components or having a remaining amount equal to or less than the set number is replaced with a new feeder 20. However, only one of them may be replaced. Good. In addition, when a feeder that needs to be replaced immediately or immediately occurs, and when the feeder 20 is replaced, it is expected that such a state will be reached in the near future although it is not yet in such a state. If there is a feeder 20, it is also possible to exchange the feeder 20 together. For example, if there is a feeder 20 in which the remaining amount of electronic components is equal to or less than the second set number that is greater than the set number as the first set number, the feeder 20 is also replaced. Since the number of the first set numbers is small even if electronic components remain in the taped electronic component 100, the taped electronic component 100 is in principle discarded. However, since the second set number is set to a relatively large value, it is desirable that the replaced taped electronic component 100 is not discarded but used later. It is used for assembling an electronic circuit with a small number of lots, or connected to another taped electronic component 100 to be used as a long taped electronic component. According to this aspect, the detaching operation of the feeder 20 can be performed to some extent, so that the number of times the table 22 can be moved between the component supply area and the retreat area can be reduced, and the work efficiency can be improved. Can be achieved.

  Furthermore, in the above-described embodiment, the visible light emitted from the LEDs 210 of the first and second light projecting devices 202 and 204 has a common color, but the first light projecting device 202 and the second light projecting device 202 have the same color. The light device 204 may have a different color, or each of the first and second light projecting devices 202 and 204 may be provided with two LEDs having different colors. In the latter case, for example, LEDs of different colors can be turned on when the feeder 20 is instructed and when a work error is notified.

  Since the configuration of each feeder is not directly related to the present invention, it will be briefly described. The configuration of the feeder 410 in the above-described embodiment partially matches, and therefore, the description of the matching portions is omitted by using common reference numerals, and only different portions are described.

  As shown in FIG. 10, the feeder 410 includes a feeder main body 460, and is fed one pitch at a time while peeling the cover tape 102 from the taped electronic component 100 by the feeding device 112. A driving source of the feeding device 112 of the feeder 410 is fixedly provided on the base 400 at a position corresponding to each feeder 410 although illustration is omitted. In the present embodiment, a storage box 468 including a pair of feed rollers 464 and 466 is attached as a cover tape storage means of each feeder 410. A pair of feed rollers 464 and 466 are attached to the opening 470 of the storage box 468, and the cover tape 102 sandwiched between the feed rollers 464 and 466 is fed into the storage box 468 as the feed rollers 464 and 466 rotate.

  The storage box 468 is made of a transparent plastic material, and the amount of the cover tape 102 in the storage box 468 can be visually confirmed. An accommodation amount sensor 474 is provided on a pair of side walls 472 and 473 that are opposed to each other in the front-rear direction of the accommodation box 468. The accommodation amount sensor 474 is a photoelectric sensor including a light emitting body 476 and a light receiving body 478 attached in the vicinity of the upper end portions of the side walls 472 and 473, and detects the amount of the cover tape 102 in the accommodation box 468. The light projected from the light emitter 476 into the housing box 468 is received by the light receiver 478 provided in front of it. When the amount of the cover tape stored in the storage box 468 is less than the upper limit value, the cover tape 102 does not exist on the straight line connecting the light emitter 476 and the light receiver 478, so that the light reaches the light receiver 478. However, when the capacity of the cover tape 102 approaches the upper limit value, the cover tape 102 exists between the light emitter 476 and the light receiver 478, thereby reducing the light reaching the light receiver 478. The accommodation amount sensor 474 determines whether or not the accommodation amount of the cover tape 102 has reached an upper limit value based on whether or not the amount of light reaching the photoreceptor exceeds a specified value. .

  The storage box 468 is opened upward, and a lid 480 is attached to the opening so as to be opened and closed. The lid 480 is opened when scraping the cover tape 102 accumulated in the storage box 468, and is closed in other cases.

  Furthermore, in this electronic component mounting system, as shown in FIG. 11, a reel attachment / detachment sensor 500 that detects attachment / detachment of the supply reel 104 is provided on the reel holder 108. In the drawing, only the reel holder 108 of the feeder 410 is shown enlarged. The reel attachment / detachment sensor 500 is a photoelectric sensor including a light emitter 502 and a light receiver 504 attached to face each other at positions separated in the front-rear direction across the supply reel 104 in the reel holder 108. The presence of the supply reel 104 in the reel holder 108 is detected. Light projected from the light emitter 502 toward the inside of the reel holder 108 is received by the light receiver 504 provided in front of the light holder 502. When the amount of the taped electronic component 100 wound around the supply reel 104 is sufficient, the taped electronic component 100 exists between the light emitter 502 and the light receiver 504, so that the light is blocked by light blocking. 504 is not reached. On the other hand, when the remaining amount of the taped electronic component 100 decreases and when the supply reel 104 is removed, the taped electronic component 100 does not exist on the line connecting the light emitter 502 and the light receiver 504. Light reaches the photoreceptor 504. The reel attachment / detachment sensor 500 detects the presence of the supply reel 104 if the remaining amount of the taped electronic component 100 wound around the supply reel 104 is sufficient, but the remaining amount of the taped electronic component 100 falls below a certain amount. Then, while the supply reel 104 is removed, the supply reel 104 is not detected. When a new supply reel 104 is attached, the presence of the supply reel 104 is detected again. If a signal indicating that the supply reel 104 is not detected is output and a signal indicating that the supply reel 104 is detected is output again, the control device 300 determines that one reel removal / removal operation has been performed. Yes.

  Further, in this electronic component mounting system, although not shown, a work support device 200 that supports the work performed by the worker is fixedly provided at a position corresponding to each electric component supply device. Since this work support apparatus 200 has essentially the same configuration as the above-described embodiment, illustration and description thereof are omitted. In the present embodiment, the mounting head 450, the drive source of the feeding device 112 of the feeder 410, and the work support device 200 are disposed so as not to interfere with each other.

Several operations on the feeder 410 in the electronic component mounting system having the above configuration will be described.
First, an intermediate operation that does not involve the removal of the feeder 410 will be described. The intermediate work is, for example, a scraping work for scraping the cover tape 102 in the storage box 468, a splicing work for the taped electronic component 100, or the like. In the splicing operation, the tip of the new taped electronic component 100 is connected to the end of the remaining taped electronic component 100, and the front and rear two taped electronic components 100 are just one taped electronic component 100. However, since it is almost the same as that described in Japanese Patent Laid-Open No. 11-40984, illustration and detailed description thereof are omitted.

  The scraping work for scraping the cover tape 102 is performed as follows. In the present embodiment, as described above, the storage box 470 is provided with the storage sensor 474 that detects the storage capacity of the cover tape 102, and if the storage capacity of the cover tape 102 reaches a predetermined upper limit value. , That is recognized. Hereinafter, description will be given based on the flowchart shown in FIG.

  If the capacity sensor 474 outputs a signal indicating that the capacity of the cover tape 102 has reached the upper limit, the determination in S202 is YES, and the feeder 410 is indicated to the operator by the control device 300. In S203, the light projecting device 202 of the instruction / detection unit 208 corresponding to the feeder 410 having the storage box 470 whose storage capacity has reached the upper limit in the work support apparatus 200 is turned on, and a part of the feeder 410 (for example, the storage box) The visible light is irradiated to the lid body 480) of 470 and the flag F4 is set to 1. Thereafter, the execution of S201 to S203 is skipped until the scraping operation for one feeder 20 is completed. Based on the lighting of the light projecting device 202, the operator opens the cover of the storage box 470, which is the object, scrapes out the cover tape 102, and remains in the storage box 470 by an appropriate length. Disconnect. Note that the lower light projecting device 204 may be turned on / off in synchronization with the lighting / extinguishing of the light projecting device 202, but when the feeder 410 is attached to the feeder support device, the lower light projecting device 204 Since the light cannot be seen, in this embodiment, the light projecting device 204 is not turned on during the intermediate work.

  If the cover tape 102 is scraped from the storage box 470, the light projected by the light emitter 476 in the storage amount sensor 474 can be continuously received by the light receiver 478 for a set time or longer. The determination in S204 is YES assuming that the capacity of the tape 102 has not reached the upper limit. In response, the projector 202 is turned off in S205, and the operator is informed that the intermediate work has been performed correctly.

  It should be noted that the upper limit value of the storage amount of the cover tape 102 of the storage box 470 can be set to a relatively small value. In such a case, a time from when it is detected by the control device 300 that the storage capacity has reached the upper limit value until it becomes impossible to store the cover tape 102 in the storage box 470 is reached. Because it is long, it does not have to be scraped immediately when the capacity of the storage box 470 reaches the upper limit in one feeder 410, but when another requirement is satisfied, the scraping work Can be performed. For example, a set time has elapsed since the capacity reached the upper limit in one feeder 410, or the number of feeders 410 whose capacity reached the upper limit exceeded the set number, or both Another requirement is that any one of the conditions is satisfied.

  Next, the splicing work will be described based on the flowchart shown in FIG. If there is no electronic component in the feeder 410 included in the electronic component supply apparatus (in this case, the electronic component supply apparatus 406) that actually supplies the electronic component, or if the remaining amount of the electronic component is less than the set number, In the same manner as in the embodiment, the determination in S302 is YES, and in S303, it is instructed to perform the splicing work for the feeder 410. As in the case where the scraping work for scraping the cover tape 102 is required, the light projecting device 202 of the instruction / detection unit 208 corresponding to the feeder 410 that requires the splicing work in the work support device 200 is turned on in S304. Then, visible light is irradiated to a part of the feeder 410, and the mounting head 450 is shifted to a state of receiving an electronic component from the other electronic component supply device 408. In the present embodiment, as described above, an electronic component is supplied from one of the electronic component supply devices 406 and 408 and the electronic component is mounted on the printed wiring board 16. Therefore, when a splicing operation is instructed for one electronic component supply device 406, the mounting head 450 is first shifted to a state of receiving an electronic component from the other electronic component supply device 408. As a result, the feeder 410 to be spliced this time is in a resting state, so that the worker can perform the splicing work with peace of mind.

  In the present embodiment, as described above, the light projecting device 202 of the same instruction / detection unit 208 is turned on when the scraping operation of the cover tape 102 is necessary and when the splicing operation is necessary. . The operator is informed that the feeder 410 needs some intermediate work, and accordingly, the operator observes the storage box 470 of the feeder 410 and the supply reel 104 and the cover tape 102 It is judged whether scraping work is necessary or splicing work is necessary, and either work is performed. Normally, it is obvious which work is necessary, but in rare cases, it is not clear which work is necessary and the light projecting device 202 is turned on. However, even in that case, it is only necessary to perform an intermediate work that the worker thinks is correct. As a result, if the light projecting device 202 is turned off, it can be confirmed that the intermediate work performed by the user is correct. However, the light projecting device 202 projects light of different colors for a plurality of intermediate operations, such as when scraping work of the cover tape 102 is required and when splicing work is required. It is also possible to project light, and by doing so, it is possible to clearly indicate to the worker what is necessary among the plurality of intermediate operations.

  If the splicing operation is performed in response to the lighting of the light projecting device 202, the reel attachment / detachment sensor 500 of the feeder 410 outputs a signal indicating that the supply reel 104 is not detected once, and then detects the supply reel 104 again. Output a signal indicating that As a result, the determination in S305 is YES, the process proceeds to S306, the light projecting device 202 is turned off, and the operator is informed that the intermediate work has been performed correctly.

  Note that the reel attaching / detaching sensor 500 may not be provided, and a signal indicating that the splicing operation has been performed by the operator may be input to cause the control device 300 to recognize that one intermediate operation has been completed.

  In addition, when splicing is performed, the taped electronic component that has been supplying the electronic component is not discarded, so the above set number of remaining electronic components should be set to a relatively large value. Can do. In such a case, since it takes a long time for the electronic device to run out after the control device 300 detects that the remaining amount is less than or equal to the set number, the electronic component of the electronic component can be reduced in one feeder 410. The splicing operation does not necessarily have to be performed immediately when the remaining amount becomes equal to or less than the set number, and the splicing operation can be performed when another requirement is satisfied. For example, the setting time has elapsed since the remaining amount of electronic components in one feeder 410 has become less than the set number, or the number of feeders 410 in which the remaining amount has become less than the set number has exceeded the set number. The above-mentioned another requirement can be that either one of these conditions is satisfied. Further, it is possible to detect both the absence of electronic components in any of the feeders 410 and the fact that the remaining amount of electronic components has become a relatively large number or less, and when the former is detected, the electronic components are detected. The electronic component supply devices 406 and 408 for supplying the components are replaced, and at that time, not only the feeder 410 with no electronic components but also the feeder 410 with the remaining amount equal to or less than the set number is spliced. It is also possible to do so.

  Next, a description will be given of the feeder attaching / detaching operation. When the attachment / detachment work is supported by the work support device, the pair of light projecting devices 202 may be simultaneously turned on / off in each instruction / detection unit 208 as in the above-described embodiment. Turns on and off. This aspect can also be applied to the electronic component mounting system. Hereinafter, description will be given based on the flowchart shown in FIG.

  If an instruction to replace the feeder 410 is issued by the control device 300 in S402, the mounting head 450 is moved from the table having the feeder 410 to be replaced to the opposite table in S403. Next, in S404, the first light projecting device 202 of the target instruction / detection unit 208 is turned on so that a part of the feeder 410 is irradiated with visible light, and a part of the upper surface of the feeder 410 is seen bright. At the same time, the flag F6 is set to 1, and thereafter the execution of S401 to S404 is skipped. If the correct feeder 410 is removed by the operator, the target instruction / detection unit 208 outputs a signal indicating that the feeder 410 is not detected, so the determination in S406 is YES. In S407, the first light projecting device 202 is turned off and the second light projecting device 204 is turned on so that the corresponding slot 180 appears bright. Thus, the operator recognizes that the removal work has been performed correctly. To do. At the same time, the flag F7 is set to 1, and thereafter, the execution of SS407 without S405 is skipped. On the other hand, if the removed feeder 410 is wrong, a signal indicating that the feeder 410 is not detected is output from a different instruction / detection unit 208. Therefore, the determination in S406 is NO, and the process proceeds to S408. Thus, the projectors 202 and 204 corresponding to the slot 180 from which the feeder 410 has been removed are blinked, and the operator is notified of the error.

  When the new feeder 410 is attached, since the second light projecting device 204 is turned on, the operator may attach the feeder 410 to the slot 180 that appears bright. If the feeder barcode is correct and the feeder 410 is correctly installed in the slot 180, the feeder 410 is detected by the feeder detection device 206, and the determinations in S409 and S410 are YES based on the detection signal. The two floodlights 204 are turned off. Thereby, the operator can confirm that the attachment work of the feeder 410 is correct, and one detachment work is completed. On the other hand, if the type of the feeder 410 is wrong or the feeder 410 is installed in the wrong slot 180, determination of at least one of S409 and S410 is NO, and the process proceeds to S408, where the feeder 20 is erroneously installed this time. The light projecting devices 202 and 204 of the instruction / detection unit 280 corresponding to the slot 180 are blinked. Since the second light projecting device 204 corresponding to the correct slot 180 is lit, the operator can easily remove the feeder 410 and remount it at the correct position.

  As is apparent from the above description, in the present embodiment, the capacity sensor 474 and the reel attachment / detachment sensor 500 constitute an “intermediate work detection device”, respectively, a part for executing S204 and S205 of the control device 300, and S305. And the part that executes S306 constitute an “intermediate work suitability display device”. Further, in the control device 300, the part that executes S408 and S410 constitutes an “attachment suitability display device”, and the part that executes S406 to S408 constitutes a “detachment suitability display device”.

  In this electronic component mounting system, the electronic component supply devices 406 and 408 are fixedly provided, and the work position for performing work on the feeder 410 and the component supply position for supplying the electronic component are common. The intermediate operation can be performed in parallel with component supply, that is, component mounting for mounting an electronic component on a printed wiring board. Therefore, in the above-described embodiment, when at least a part of the intermediate work, for example, the scraping work of the cover tape 102 is executed, the component supply device on the side where the mounting head 450 actually supplies the component is transferred to the other. Although not moved, when the scraping operation of the cover tape 102 is executed, the electronic component is supplied from the other component supply device instead of the component supply device having the feeder 410 to which the operation is to be performed. The mounting head 450 may be moved as described above.

  In the above embodiment, only the light projecting device 202 of the instruction / detection unit 208 corresponding to the feeder 410 to be subjected to the intermediate work is turned on, but at the same time, intermediate work such as scraping work or splicing work on the monitor or the like. A display for instructing the type may be output. If an instruction indicating which of the plurality of types of intermediate work is to be performed is performed in a manner that is recognizable to the worker, the worker can more easily and reliably perform the work. Further, the number of the feeder 410 that should perform the detaching operation may be displayed on the monitor.

  In the present embodiment, the two electronic component supply devices 406 and 408 are provided, but only one of the electronic component supply devices may be provided. In such a case, the intermediate operation can be performed in parallel with the electronic component mounting operation, but the feeder detachment operation is preferably performed with the execution of the electronic component mounting operation stopped.

  As mentioned above, although some embodiment of this invention was described in detail, these are only illustrations and this invention was described in the above-mentioned section of [the subject which invention intends to solve, a problem-solving means, and an effect]. The present invention can be implemented in various forms including various modifications and improvements based on the knowledge of those skilled in the art.
