connectors

35 and 22c.

As shown in FIG. 2 and FIG. 4, an upper guide rail 40, a lower guide rail 42, a rack gear 44, and a non-contact power supply coil 46 are provided on the front surface of the component mounting machine 20. The upper guide rail 40 is a rail having a U-shaped cross section that extends in the X direction, and an opening portion faces downward. The lower guide rail 42 is a rail having an L-shaped cross section extending in the X direction, a vertical surface is attached to the front surface of the component mounting machine 20, and a horizontal surface extends forward. The rack gear 44 is a gear that extends in the X direction and has a plurality of vertical grooves formed on the front surface. The non-contact power supply coil 46 is a coil disposed along the X direction. The upper guide rail 40, the lower guide rail 42, and the rack gear 44 of the component mounter 20 can be detachably connected to the upper guide rail 40, the lower guide rail 42, and the rack gear 44 of the adjacent component mounter 20. Therefore, the component mounting machines 20 are standardized, and the number of the component mounting machines 20 arranged in the mounting line 12 can be increased or decreased.

As shown in FIG. 4, the loader 50 is configured in two upper and lower stages, the lower stage being a traveling platform 52, and the upper stage being a feeder storage unit 70.

The traveling platform 52 includes an upper roller 54, a lower roller 56, a pinion gear 58, a traveling motor 60, and a non-contact power receiving coil 62. The upper roller 54 is inserted upward from the opening of the upper guide rail 40 and is supported so as to be capable of rolling with the side wall of the upper guide rail 40. The lower roller 56 is supported so as to be able to roll and engage with a horizontal plane of the lower guide rail 42. The pinion gear 58 is meshed with the rack gear 44. The travel motor 60 has a motor shaft connected to the rotation shaft of the pinion gear 58. When the pinion gear 58 meshed with the rack gear 44 extending in the X direction is rotated by the traveling motor 60, the upper roller 54 rolls on the side wall of the upper guide rail 40 and the lower roller 56 rolls on the horizontal plane of the lower guide rail 42. While moving, the traveling platform 52 and thus the loader 50 moves in the X direction. On the other hand, the non-contact power receiving coil 62 faces the non-contact power supply coil 46 of the component mounting machine 20 while maintaining a predetermined distance, and receives electric power necessary for operations such as traveling of the loader 50 from the component mounting machine 20. The non-contact power receiving coil 62 may charge the power received from the component mounter 20 to a battery (not shown), and use the power of the battery for operations such as running. The traveling platform 52 further includes a loader control device 64 and an encoder 66, as shown in FIG. The loader control device 64 includes a known CPU, ROM, HDD, RAM, and the like. The encoder 66 detects the position of the loader 50 in the X direction and outputs it to the loader control device 64.

The feeder storage unit 70 stores the feeder 30 to be replenished to the component mounting machine 20, and stores the feeder 30 collected from the component mounting machine 20. The feeder storage unit 70 includes a feeder transfer mechanism 72, a barcode reader 74, and a microphone 76. The feeder transfer mechanism 72 supplies and collects the feeder 30. Specifically, the feeder transfer mechanism 72 clamps the feeder 30 stored in the feeder storage unit 70 and moves it back along the Y-axis when the feeder 30 is replenished to the component mounting machine 20 to mount the component. It is inserted into an empty slot 22 a of the feeder base 22 of the machine 20. Further, when the feeder transfer mechanism 72 collects the feeder 30 from the component mounter 20, the feeder transfer mechanism 72 clamps the feeder 30 held on the feeder base 22 of the component mounter 20 and moves it forward along the Y axis. It is pulled out from the feeder base 22 and stored in the feeder storage unit 70. Electric power necessary for the feeder transfer mechanism 72 is supplied from the component mounting machine 20 via the non-contact power supply coil 46. The barcode reader 74 reads the barcode 38 of the feeder 30 stored in the feeder storage unit 70 and outputs the read information to the loader control device 64. The microphone 76 is attached to the top plate of the feeder storage unit 70 so as to face the component mounting machine 20 (mounting line 12). The microphone 76 has high directivity (for example, unidirectionality or superdirectivity). The sound picked up by the microphone 76 is recorded in the internal memory (HDD or RAM) of the loader control device 64.

The management computer 80 includes a known CPU, ROM, HDD, RAM, and the like, and includes a display 82 such as an LCD and an input device 84 such as a keyboard and a mouse as shown in FIG. Production job data is stored in the HDD of the management computer 80. In the production job data, it is determined which parts are to be mounted on the board S in each component mounting machine 20 and in what order, and how many boards S are mounted in such a manner. The management computer 80 is connected to the mounting control device 28 of each component mounting machine 20 so that bidirectional communication is possible. The management computer 80 can communicate bidirectionally with the loader control device 64.

Next, the operation of the component mounter 20 will be described. The mounting control device 28 of the component mounter 20 controls the head moving mechanism 24 so that the nozzle of the head 23 comes to the component supply position of the feeder 30, and causes the component supplied by the feeder 30 to be attracted to the nozzle. Thereafter, the mounting control device 28 controls the head moving mechanism 24 so that the component sucked by the nozzle comes to a predetermined mounting position of the substrate S, releases the suction of the component by the nozzle, and mounts the component at the mounting position. To do. The mounting control device 28 performs this mounting operation for all components to be mounted on the substrate S. Also, the mounting control device 28 performs component mounting on the number of boards S set in the production job data.

The mounting control device 28 of the component mounting machine 20 subtracts the number of remaining parts of the feeder 30 every time a part is taken out from the feeder 30, and when the remaining number of parts of the feeder falls below a predetermined threshold value, the component breakage occurs. A component supply request is output to the management computer 80, assuming that it is approaching.

The management computer 80 that has input the replenishment request displays on the display 82 a screen for instructing the operator to set the feeder 30 that contains the component type that requires component replenishment in the feeder storage unit 70 of the loader 50. After viewing this screen, the operator sets the feeder 30 that stores the component type in the feeder storage unit 70 of the loader 50. When the feeder 30 is set in the feeder storage unit 70, the barcode 38 of the feeder 30 is read by the barcode reader 74, and the serial ID of the barcode 38 is transmitted from the loader control device 64 to the management computer 80. Since the management computer 80 stores data related to parts for each serial ID in the HDD, the management computer 80 determines whether or not the part type of the feeder 30 set in the loader 50 is the same as the part type requested to be replenished. If the two types of parts are not the same, the management computer 80 notifies an error. If both types of parts are the same, the management computer 80 outputs a feeder replacement request to the loader control device 64. The feeder replacement request is a command for instructing the loader 50 to perform feeder replacement in the component mounter 20 that has output the supply request. In the feeder replacement request, the position information of the slot 22a of the feeder base 22 of the component mounter 20, specifically, the position information of the slot 22a into which the feeder 30 to be replenished is inserted and the feeder 30 that has run out of parts are inserted. The position information of the slot 22a is also included.

When the loader control device 64 receives a feeder replacement request from the management computer 80, the loader control device 64 controls the traveling motor 60 so that the loader 50 comes to a position in front of the component mounter 20 that has output the replenishment request. Specifically, the traveling motor 60 is controlled so that the feeder 30 set in the feeder storage unit 70 faces the slot 22a into which the feeder 30 is inserted. In this state, the loader control device 64 controls the feeder transfer mechanism 72 so that the feeder 30 set in the feeder storage unit 70 is inserted into the opposing slot 22a. As a result, a new feeder 30 is supplied to the component mounter 20.

Thereafter, the loader control device 64 controls the traveling motor 60 so that the feeder collection position of the feeder storage unit 70 faces the feeder 30 in which the parts of the feeder base 22 have been cut. In this state, the loader control device 64 controls the feeder transfer mechanism 72 so that the feeder 30 that has run out of parts is pulled into the feeder collection position of the feeder storage unit 70. As a result, the feeder 30 that has run out of parts is collected by the loader 50.

In this way, the loader 50 automatically supplies a new feeder 30 that contains the same part as the part type that has run out of parts and collects the feeder 30 that has run out of parts. Therefore, the component mounting machine 20 performs the mounting operation only by switching the component supply position of the feeder 30 that has run out of components (the position at which the component is sucked by the nozzle provided in the head 23) to the component supply position of the new feeder 30. Production can be continued without interruption.

Next, an inspection processing routine executed by the loader control device 64 will be described. When the inspection request for the mounting line 12 is input from the management computer 80 during the component mounting operation of the component mounting machine 20, the loader control device 64 reads the inspection program from the ROM and executes the inspection processing routine. It is assumed that the management computer 80 periodically transmits an inspection request for the mounting line 12 to the loader control device 64. FIG. 6 is a flowchart illustrating an example of the inspection processing routine.

When starting the inspection processing routine, the loader control device 64 first determines whether or not the loader 50 is performing a feeder replenishment operation or a collection operation (S100). If the loader 50 is performing an operation, the loader control device 64 again. Return to S100. That is, the loader control device 64 waits until the work of the loader 50 is completed. On the other hand, if the loader 50 has not performed the work in S100, the loader control device 64 resets n, which is a variable of the counter included in the loader control device 64, to zero (S110). Subsequently, the loader control device 64 increments n by 1 (S120), and controls the traveling motor 60 so that the loader 50 stops at a position facing the nth component mounting machine 20 (S130). Here, the first component mounter 20, the second component mounter 20, and so on are counted in order from the left side to the right side of the mounting line 12. Subsequently, the loader control device 64 records the operation sound picked up by the microphone 76 over a predetermined time in the internal memory (HDD or RAM) (S140). The predetermined time may be, for example, a time from when the board S is carried into the component mounter 20 facing the loader 50 until it is carried out, or may be a time when allowance is provided. The sound recorded in the internal memory in S140 is mainly an operation sound of the nth component mounter 20. Subsequently, the loader control device 64 determines whether or not n has reached the upper limit (S150). If n has not reached the upper limit, the process returns to S120 again. Note that the upper limit of n is the total number of component mounters 20 constituting the mounting line 12. On the other hand, if n has reached the upper limit in S150, the loader control device 64 determines the presence or absence of abnormality based on the operation sound recorded for each component mounter 20 (S160). For example, the loader control device 64 analyzes the recorded operation sound and detects an abnormal sound component that cannot be generated by a normal component mounting operation (for example, a sound component in a specific frequency range or a sound component having a magnitude exceeding a predetermined threshold). Etc.) may be determined based on whether or not there is an error. Alternatively, when the result of the inspection of the component mounting machine 20 is satisfactory, the operation sound immediately after the inspection is recorded and used as a reference sound (normal operation sound), and the reference sound and the recorded operation sound are used. The presence or absence of abnormality may be determined by comparison. Thereafter, the loader control device 64 outputs the determination result to the management computer (S170) and ends this routine.

When the management computer 80 inputs the determination result from the loader control device 64, the management computer 80 displays the determination result on the display 82. If no abnormality is found in all the component mounting machines 20, the management computer 80 displays that fact on the display 82. When there is a component mounter 20 in which an abnormality is found, the management computer 80 displays on the display 82 content indicating what number component mounter 20 is likely to cause an abnormality. The operator who sees this display performs the inspection work of the component mounter 20 that may cause an abnormality.

Here, the correspondence between the constituent elements of the present embodiment and the constituent elements of the present disclosure will be clarified. The component mounting system 10 of the present embodiment corresponds to the component mounting system of the present disclosure, the mounting line 12 corresponds to a mounting line, the loader 50 corresponds to a mobile work device, the sound corresponds to a physical quantity, and the microphone 76 It corresponds to a physical quantity detection unit, and the loader control device 64 corresponds to a determination device.

In the component mounting system 10 according to the first embodiment described above, the loader 50 moving along the mounting line 12 includes the microphone 76, and the loader control device 64 sets the mounting line 12 based on the operation sound detected by the microphone 76. The presence / absence of abnormality of the component mounter 20 to be configured is determined. That is, the microphone 76 need only be provided in the loader 50. Therefore, it is possible to determine whether or not there is an abnormality in the component mounter 20 configuring the mounting line 12 without providing a microphone for each component mounter 20 configuring the mounting line 12.

Further, the loader 50 moves so as to sequentially face a plurality of component mounting machines 20 arranged on the mounting line 12, and the microphone 76 detects an operation sound of the component mounting machine 20 that the loader 50 faces to perform loader control. The device 64 determines whether there is an abnormality in the component mounter 20 that the loader 50 faces based on the operation sound. Therefore, it is possible to determine whether there is an abnormality for each component mounting machine 20.

[Second Embodiment]
Compared with the first embodiment, the second embodiment is the same as the first embodiment except that the microphone 76 is omnidirectional (omnidirectional) and the inspection processing routine is different. Therefore, the inspection processing routine will be mainly described below. FIG. 7 is a flowchart illustrating an example of an inspection processing routine according to the second embodiment.

When starting the inspection processing routine, the loader control device 64 first determines whether or not the loader 50 is performing a feeder replenishment operation or a collection operation (S200). If the loader 50 is performing an operation, the loader control device 64 again. Return to S200. That is, the loader control device 64 waits until the work of the loader 50 is completed. On the other hand, if the loader 50 has not performed the work in S200, the loader control device 64 controls the traveling motor 60 so that the loader 50 stops at the center of the mounting line 12 (S210). Subsequently, the loader control device 64 records the sound picked up by the microphone 76 over a predetermined time in the internal memory (HDD or RAM) (S220). Here, the operation sound generated in all the component mounting machines 20 constituting the mounting line 12 is recorded. In this embodiment, since the microphone 76 is omnidirectional, it is suitable for recording such operation sound. The predetermined time may be, for example, a time from when one board S is carried in the upstream side of the mounting line 12 until it is carried out from the downstream side, or one board S is attached to one component mounting machine 20. It is good also as time until it is carried out after carrying in, It is good also as time which considered allowance for these. Subsequently, the loader control device 64 determines whether or not there is an abnormal one among the plurality of component mounting machines 20 arranged on the mounting line 12 based on the recorded entire operation sound (S230). Here, the loader control device 64 analyzes the recorded operation sound and determines whether there is an abnormality depending on whether or not an abnormal sound component that cannot be generated in a normal component mounting operation is included. Thereafter, the loader control device 64 outputs the determination result to the management computer (S240), and ends this routine.

When the management computer 80 inputs the determination result from the loader control device 64, the management computer 80 displays the determination result on the display. When no abnormality is found in the entire mounting line 12, the management computer 80 displays that fact on the display 82, and when there is an abnormality, the plurality of component mounting machines arranged on the mounting line 12. 20 displays on the display 82 that there is a possibility that there is an abnormal item. The operator who sees this display performs the inspection work of the plurality of component mounting machines 20 constituting the mounting line 12 that may cause an abnormality.

In the component mounting system 10 according to the second embodiment described above, the loader 50 moving along the mounting line 12 includes the microphone 76, and the loader control device 64 configures the mounting line 12 based on the sound detected by the microphone 76. The presence or absence of abnormality of the component mounter 20 to be determined is determined. That is, the microphone 76 need only be provided in the loader 50. Therefore, it is possible to determine whether or not there is an abnormality in the component mounter 20 configuring the mounting line 12 without providing a microphone for each component mounter 20 configuring the mounting line 12.

In addition, the microphone 76 detects the entire operation sound of the mounting line 12, and the loader control device 64 is among the plurality of component mounting machines 20 arranged on the mounting line 12 based on the operation sound detected by the microphone 76. It is determined whether there is an abnormal item. Therefore, it is possible to know whether or not there is an abnormal one among the plurality of component mounters 20 arranged on the mounting line 12.

[Third Embodiment]
The third embodiment is different from the first embodiment except that the unidirectionality and omnidirectionality (omnidirectionality) of the microphone 76 can be switched by the loader control device 64 and the inspection processing routine is different. Is the same as in the first embodiment. Therefore, the inspection processing routine will be mainly described below. FIG. 8 is a flowchart illustrating an example of an inspection processing routine according to the third embodiment.

When the loader control device 64 starts the inspection processing routine, it executes the processing of S200 to S230. Since the processing of S200 to S230 has been described in the second embodiment, the description thereof is omitted here. The microphone 76 is set to be omnidirectional before recording in S220. After S230, the loader control device 64 determines whether or not there is an abnormality in the plurality of component mounting machines 20 arranged on the mounting line 12 (S232). 80 (S234), and this routine is terminated. On the other hand, if there is an abnormality in S232, the loader control device 64 executes the processing of S110 to S170. Since the processing of S110 to S170 has been described in the first embodiment, the description thereof is omitted here. The microphone 76 is set to be unidirectional before recording at S140.

In the component mounting system 10 of the third embodiment described above, the same effect as that of the second embodiment can be obtained. In addition, the loader control device 64 first determines whether or not there is an abnormal one among the plurality of component mounters 20 arranged on the mounting line 12. The presence or absence of abnormality is determined for each machine 20. For this reason, the time required for the determination is shortened compared to the case where the presence / absence of abnormality is determined for each component mounter 20 from the beginning.

[Other Embodiments]
It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that the present invention can be implemented in various modes as long as it belongs to the technical scope of the present invention.

For example, in each of the embodiments described above, sound is used as the physical quantity and the microphone 76 is used as the physical quantity detection unit. Instead, vibration is used as the physical quantity, and vibration of the component mounter 20 is detected as the physical quantity detection unit. A vibration detection sensor may be employed. In that case, the presence / absence of abnormality of the component mounter 20 may be determined based on the detected vibration level (magnitude). Alternatively, a temperature detection sensor that employs temperature as the physical quantity and detects the temperature of the component mounting machine 20 may be employed as the physical quantity detection unit. In that case, the presence / absence of abnormality of the component mounter 20 may be determined based on the detected temperature. Note that temperature and vibration may take some time to change after an abnormality occurs in the component mounting machine 20, but the sound changes abnormally since the abnormality occurs in the component mounting machine 20. It is easy to detect the presence or absence. In this respect, it is preferable to employ sound as a physical quantity.

In each of the above-described embodiments, the loader control device 64 determines whether there is an abnormality based on the recording data (operation sound). However, the loader control device 64 transmits the recording data to the management computer 80 and receives it. 80 may determine whether there is an abnormality. In that case, the management computer 80 serves as a determination device.

In each of the embodiments described above, the microphone 76 is attached to the top plate of the feeder storage unit 70. However, the present invention is not limited to this, and the microphone 76 may be attached to the side surface of the carriage 52 or the side surface of the feeder storage unit 70. It may be built in the loader 50.

In each of the above-described embodiments, the management computer 80 displays the determination result on the display 82. Instead of or in addition to this, the loader control device 64 may display the determination result on its own display, or the implementation control. The device 28 may acquire the determination result from the loader control device 64 and display it on its own display.

In S160 of the first and third embodiments described above, it is determined whether or not there is an abnormality in each component mounter 20 after the operation sounds of all the component mounters 20 constituting the mounting line 12 have been recorded. Each time the operation sound of the component mounter 20 is recorded, it may be determined whether or not the component mounter 20 is abnormal.

As operations, for example, an operation in which the substrate transport device 21 carries in the substrate S, an operation in which the feeder 30 supplies components, an operation in which the nozzles of the head 23 suck components from the tape, and a head moving mechanism 24 moves the head 30. An operation, an operation in which the nozzle of the head 23 mounts a component on the substrate S, an operation in which the substrate transport device 21 carries out the substrate S, and the like are included. When recording the operation sound for each operation of the component mounter 20, the component mounter 20 notifies the loader control device 64 of the start and end of the operation of each process, and the loader control device 64 notifies the loader 50 in accordance with the notification. The operation sound may be recorded by moving to a position facing the component mounting machine 20.

In the second embodiment described above, the loader 50 is moved to the center of the mounting line 12 in S210. However, any position other than the center of the mounting line 12 may be used as long as the operation sound of the entire mounting line 12 can be picked up.

In the third embodiment described above, the microphone 76 capable of switching between unidirectionality and omnidirectionality is used, but two unidirectional microphones and omnidirectional microphones are attached to the loader 50, and In S220, an omnidirectional microphone may be used, and in S140, a unidirectional microphone may be used.

In each of the above-described embodiments, the feeder 30 is exemplified as the component supply device. However, the feeder 30 is not particularly limited to the feeder 30, and may be a unit that supplies a component tray or a component tray, for example. Further, the component supply device is not limited to a device that supplies components mounted on the substrate S like the feeder 30. For example, a device that supplies a head, or a nozzle that supplies a replacement nozzle attached to the head. It may be a stocker.

In each of the above-described embodiments, an example in which the loader 50 performs both replenishment and collection of the feeder 30 has been shown. However, the present invention is not particularly limited to this, and for example, the loader 50 is only one of replenishment and collection. May be executed.

In each of the above-described embodiments, the loader 50 that travels by the travel motor 60 is exemplified as the mobile work device, but the present invention is not particularly limited thereto. For example, it may be an automated guided vehicle that travels by the magnetic induction action of a guideline embedded in the floor.

In each of the above-described embodiments, the power for operating the loader 50 is supplied from the component mounting machine 20 via the non-contact power supply coil 46, but is not particularly limited thereto. For example, a battery may be mounted on the loader 50.

In each of the above-described embodiments, the rotational motion of the traveling motor 60 is converted into linear motion using the rack gear 44 and the pinion gear 58. However, instead of the rack gear 44, a chain and a sprocket wheel instead of the pinion gear 58 are used for traveling. The rotational motion of the motor 60 may be converted into a linear motion.

In each of the above-described embodiments, the mounting line 12 includes a plurality of component mounting machines 20 arranged in the X direction. However, printing on which solder is printed on the substrate S is upstream of the component mounting machine 20 at the most upstream position. You may arrange a printing inspection machine which inspects a printing machine and its printing situation. Alternatively, a component inspection machine for inspecting components on the substrate S and a reflow machine for performing solder reflow may be arranged on the downstream side of the component mounting machine 20 at the most downstream position.

In each of the above-described embodiments, the loader control device 64 determines the presence / absence of an abnormality based on the recording data (operation sound). However, when an operation failure is estimated or when a sign of failure is recognized, Recording and recording may be performed. Possible methods for estimating defects and recognizing signs include, for example, the number of abnormal suction operations, an increase in miss rate, the number of mounting failures by an inspection machine, and an increase in defect rate. Further, when a defective part is specified by statistical processing of some defective data, the operation sound of the defective part may be recorded and recorded. By recording and analyzing the operation sound in this way, there is a possibility that the state of failure can be grasped more clearly.

[Configuration example of component mounting system of the present disclosure]
Note that the component mounting system of the present disclosure may be configured as follows.

In the component mounting system according to the present disclosure, the mobile work device moves so as to sequentially face a plurality of the component mounters arranged in the mounting line, and the physical quantity detection unit faces the mobile work device. The physical quantity related to the component mounter is detected, and the determination device determines whether there is an abnormality in the component mounter that the mobile work device faces based on the physical quantity detected by the physical quantity detection unit. May be. In this way, it is possible to determine whether there is an abnormality for each component mounter.

In the component mounting system according to the present disclosure, the physical quantity detection unit detects the physical quantity related to the entire mounting line, and the determination device is arranged on the mounting line based on the physical quantity detected by the physical quantity detection unit. It may be determined whether or not there is an abnormal one among the plurality of component mounting machines provided. In this way, it is possible to know whether or not there is an abnormal one among the plurality of component mounters arranged on the mounting line.

In this case, if it is determined that there is an abnormal one among the plurality of component mounters arranged on the mounting line, the mobile work device has a plurality of the component mounting arranged on the mounting line.
