Description

  The present invention sets a tape feeder on which a component supply tape is mounted on a component mounter, and peels a cover tape (also called a top tape, a cover film, or a top film) from the front end side of the component supply tape with the tape feeder. The component supply tape is sent to the component suction position while the electronic component in the component supply tape is exposed, and the electronic component in the component supply tape is sucked by the suction nozzle of the component mounting machine and mounted on the circuit board. The invention relates to a production management system for a mounting machine.

  In a tape feeder set in a component mounter, static electricity is generated when the cover tape is peeled off from the upper surface of the component supply tape, and the static electricity causes the electronic component to stick to the cover tape or the component supply tape cavity ( There is a possibility that the electronic component will not be stably adsorbed by the adsorbing nozzle of the component mounting machine, and the internal circuit of the electronic component may be broken by static electricity. In recent years, electronic components have become smaller and lighter, and an environment in which troubles due to static electricity generated when the cover tape is peeled off from the component supply tape is likely to occur.

  Therefore, in Patent Document 1 (Japanese Utility Model Publication No. 60-27499), a static voltage due to charging of the cover tape peeled off from the component supply tape is detected, and a high voltage of the same polarity larger than the detected voltage is detected by the tape feeding mechanism. This is applied to the sprocket roller of the machine to prevent defective parts supply due to static electricity.

  Further, in Patent Document 2 (Japanese Utility Model Laid-Open No. 5-57900), a brush portion of a conductive tool whose one end is grounded is brought into contact with a carrier tape of a component supply tape from above in the vicinity of a component suction position. The charged static electricity is released to the ground side through a conductive tool to remove the static electricity from the carrier tape.

  Further, in Patent Document 3 (Japanese Patent Application Laid-Open No. 2012-195401), at least a part of a tape path through which a component supply tape passes is charged with static electricity charged in the component supply tape in contact with or close to the component supply tape. A static elimination sheet is provided to remove static electricity charged on the component supply tape.

Japanese Utility Model Publication No. 60-27499 Japanese Utility Model Publication No. 5-57900 JP 2012-195401 A

  In general, static electricity is more likely to be generated when the cover tape is peeled from the component supply tape, as the air around the component supply tape mounted on the tape feeder dries. Further, as the time during which the component supply tape is exposed to dry air becomes longer, the amount of static electricity charged on the component supply tape tends to increase. For this reason, even if the countermeasures against static electricity described in Patent Documents 1 to 3 are taken, if the time during which the component supply tape is exposed to dry air becomes long, the ability to remove static electricity is insufficient, In the component supply tape containing the components, the above-described problems are likely to occur.

  Therefore, the problem to be solved by the present invention is to provide a production management system for a component mounting machine that can effectively prevent problems caused by the time that the component supply tape mounted on the tape feeder is exposed to dry air. It is to be.

  In order to solve the above problems, the present invention sets a tape feeder on which a component supply tape is mounted on a component mounter, and peels the cover tape from the front end side of the component supply tape with the tape feeder to supply the component. Production of a component mounter that feeds the component supply tape to a component suction position while exposing the electronic component in the tape, and sucks the electronic component in the component supply tape by the suction nozzle of the component mounter and mounts it on the circuit board. In the management system, a feeder stop time measuring means for measuring a time for which the tape feeder waits in a stopped state (hereinafter referred to as “feeder stop time”), a humidity detecting means for detecting the humidity of air in which the tape feeder exists, The tape feeder is based on the feeder stop time measured by the feeder stop time measuring means and the humidity detected by the humidity detecting means. Is obtained by a structure in which a feeder managing means for managing permission / prohibition of use of the component supply tape is attached to.

  Generally, as the air around the component supply tape mounted on the tape feeder dries, static electricity is more likely to be generated when the cover tape is peeled from the component supply tape, and problems due to static electricity are more likely to occur. Since this static electricity failure occurs near the cover tape peeling position, the longer the feeder stop time when the tape feeder is stopped, the more the component supply tape cover tape is exposed to dry air near the cover tape peeling position. When the cover tape is peeled off, the static electricity generated when the cover tape is peeled off increases, and the troubles due to static electricity tend to increase.

  Paying attention to this characteristic, the present invention measures the feeder stop time when the tape feeder is in a stopped state, detects the humidity of the air where the tape feeder exists, and applies the tape feeder to the tape feeder based on the feeder stop time and humidity. The permission / prohibition of use of the mounted component supply tape is managed. As a result, taking into account both the time during which the cover tape of the component supply tape is exposed to dry air near the peeling position (feeder stop time) and the humidity of the air, It is possible to prohibit the use of the component supply tape when the device is in a state where it is likely to cause a malfunction due to static electricity, and the component supply tape is in a dry state. It is possible to effectively prevent problems caused by the prolonged exposure to air.

  Specifically, the feeder management means applies the tape feeder to the tape feeder when the feeder stop time measured by the feeder stop time measuring means is a predetermined time or more and the humidity detected by the humidity detection means becomes a predetermined humidity or less. The use of the mounted component supply tape may be prohibited. Here, the “predetermined time” and “predetermined humidity” may be a predetermined constant value (fixed value), or may be changed depending on the material of the component supply tape, the component type, and the like. This is because the rate of occurrence of defects due to static electricity changes depending on the material of the component supply tape, the component type, and the like.

  Alternatively, the feeder management means is mounted on the tape feeder when the feeder stop time measured by the feeder stop time measuring means reaches or exceeds a predetermined time set according to the humidity detected by the humidity detection means. The use of the component supply tape may be prohibited. In this case, as the humidity of the air is lower (that is, the air is dried), static electricity is more likely to occur when the cover tape is peeled off from the component supply tape. Therefore, the lower the humidity detected by the humidity detecting means, The feeder stop time (predetermined time) until the use of the supply tape is prohibited may be set to a short time.

  The humidity detecting means may detect the humidity of the air inside the component mounter. The position where the cover tape is peeled off from the component supply tape (near the component suction position) is located inside the component mounter, and the air temperature is higher than the outside of the component mounter and the air is dry. By detecting the humidity of the air inside the machine, it is possible to accurately detect the humidity of the air near the cover tape peeling position where trouble due to static electricity occurs, and whether the trouble due to static electricity is likely to occur. Whether or not can be accurately monitored.

  By the way, in a component mounter in which a plurality of tape feeders are set, the feeder stop time differs for each tape feeder, so the time for the cover tape of the component supply tape to be exposed to dry air near the peeling position is also different for each tape feeder. Different.

  Therefore, in a component mounting machine in which a plurality of tape feeders are set, the feeder stop time measuring unit measures the feeder stop time for each tape feeder, and the feeder management unit is configured to reduce the feeder stop time and humidity for each tape feeder. Based on the above, permission / prohibition of use of the component supply tape may be managed. In this way, the tape feeder set in the component mounter is monitored for whether or not it is prone to malfunction due to static electricity, and the tape feeder that is prone to malfunction due to static electricity Only the use of parts supply tape can be prohibited.

  By the way, among the component supply tapes of a plurality of component types that can be mounted on the tape feeder, there are electronic components (for example, large components) that do not suffer from the problems caused by static electricity that occurs when the cover tape is peeled off. It is not necessary to manage permission / prohibition of use of a component supply tape of a component type that does not cause problems due to static electricity. Therefore, among component supply tapes of a plurality of component types that can be mounted on the tape feeder, component supply tapes of component types that do not cause problems due to static electricity that occurs when the cover tape is peeled off are not subject to management. Only the component supply tape of the component type that may cause a malfunction due to the above is managed, and the feeder management means uses the component supply tape only for the tape feeder equipped with the component supply tape of the component type to be managed. It is preferable to manage the permission / prohibition of the component and to permit the use of the component supply tape of the component type that is not the management target. In this way, it is not necessary to manage the component supply tape of a component type that does not cause a problem due to static electricity, and accordingly, the processing load required for managing the component supply tape can be reduced.

  Further, the feeder management means may stop the suction of the electronic component from the component supply tape determined to be prohibited and warn the operator by display and / or sound. In this way, it is possible to prompt the operator to replace the component supply tape determined to be prohibited from use at an early stage, and it is possible to more reliably prevent a malfunction due to static electricity.

FIG. 1 is a side view schematically showing a configuration of a main part of a component mounter according to an embodiment of the present invention. FIG. 2 is a block diagram showing the configuration of the control system of the component mounter. FIG. 3 is a flowchart showing the processing flow of the first half of the tape feeder management program. FIG. 4 is a flowchart showing the flow of processing in the latter half of the tape feeder management program.

Hereinafter, an embodiment embodying a mode for carrying out the present invention will be described.
First, the configuration of the component mounter 10 will be schematically described with reference to FIG.

  A plurality of tape feeders 12 are set side by side on a feeder set base 11 of the component mounter 10. Each tape feeder 12 is provided with a reel 14 around which a component supply tape 13 is wound, and the component supply tape 13 is sent from the reel 14 to a component suction position, and from the upper surface of the component supply tape 13 before the component suction position. The cover tape 15 is peeled to expose the electronic components in the carrier tape 16, and the electronic components in the carrier tape 16 are sucked by the suction nozzle (not shown) of the component mounting machine 10 at the component suction position. To implement.

  The empty carrier tape 16 discharged from the tip of the tape feeder 12 is guided by being bent downward by the tape guide passage 17, cut by a tape cutting mechanism (not shown), and slid down the chute 18 to collect the empty tape. It is collected in the box 19. The cover tape 15 peeled off from the carrier tape 16 before the component suction position of the tape feeder 12 hangs down from the tape feeder 12 and is collected in a waste tape collection box 19 positioned immediately below the tape.

  A front cover 21 is provided on the front surface of the component mounter 10 so that the front cover 21 can be opened and closed. When the front cover 21 is closed, the space inside the component mounter 10 is almost sealed and set on the feeder set base 11. A portion of the feeder 12 on the main body side (near the peeling position of the cover tape 15) is located inside the component mounter 10, and a portion on the reel 14 side is located outside the component mounter 10. Inside the component mounter 10, a humidity sensor 22 (humidity detection means) that detects the humidity of the air inside the component mounter 10 where the main body side portion of the tape feeder 12 exists is installed.

Next, the configuration of the control system of the component mounter 10 will be described with reference to FIG.
The control device 31 of the component mounter 10 is configured mainly by a computer, and includes an input device 32 such as a keyboard, a mouse, and a touch panel, a display device 33 such as a liquid crystal display and a CRT, a component mounter control program, and FIG. 4 and the storage device 34 storing the tape feeder management program and the like shown in FIG. The control device 31 of the component mounting machine 10 includes a mounting head moving device 35 that moves a mounting head (not shown) that holds the suction nozzle in the X, Y, and Z directions, and a substrate that carries a circuit board on which the electronic component is mounted. The electronic component mounting board is controlled by controlling the operations of the transport device 36, the parts camera 37 that captures the electronic component sucked by the suction nozzle from below, and the mark camera 38 that captures the reference position mark of the circuit board from above. Produce.

  Although not shown, in the production line for producing the electronic component mounting board, in addition to one or a plurality of component mounting machines 10, a solder printer for printing a solder pattern on a circuit board, or a reflow furnace for reflow soldering In addition, an inspection device or the like for inspecting the mounting state of the electronic components is arranged along the circuit board conveyance path, and production of each device in the entire production line is managed by the production management host computer 41.

  The control device 31 (or the host computer 41) of the component mounter 10 executes the tape feeder management program shown in FIGS. 3 and 4 so that the tape feeder 12 set on the component supply tape 13 waits in a stopped state ( The component supply tape 13 is mounted on the tape feeder 12 based on the measured feeder stop time and the humidity detected by the humidity sensor 22. It also functions as a feeder management means for managing permission / prohibition of use of.

  Generally, as the air around the component supply tape 13 mounted on the tape feeder 12 is dried, static electricity is more likely to be generated when the cover tape 14 is peeled from the component supply tape 13, and problems due to static electricity are more likely to occur. . Since the trouble due to static electricity occurs near the peeling position of the cover tape 15, the cover tape 14 of the component supply tape 13 becomes dry near the peeling position as the feeder stop time in which the tape feeder 12 is in a stopped state becomes longer. There is a tendency that the time of exposure to air becomes longer, static electricity generated when the cover tape 14 is peeled off, and defects due to static electricity increase.

  Focusing on this characteristic, in this embodiment, the feeder stop time during which the tape feeder 12 is stopped is measured, and a part on the main body side of the tape feeder 12 (near the peeling position of the cover tape 15) is present. From the component supply tape 13, the humidity of the air inside the mounting machine 10 is detected and the cover tape 15 of the component supply tape 13 is exposed to dry air near the peeling position and the air humidity is taken into consideration. When the cover tape 15 is peeled off, it is monitored whether or not a failure due to static electricity is likely to occur, and the use of the component supply tape 13 is prohibited when the failure due to static electricity is likely to occur. I have to.

  In this embodiment, in addition to the function of prohibiting the use of the component supply tape 13, it is possible to arbitrarily select the function of slowing the peeling operation of the cover tape 15, and the operator selects the latter function. In this case, when it is determined that a problem due to static electricity is likely to occur when the cover tape 15 is peeled off based on the measured feeder stop time and humidity, the peeling operation of the cover tape 15 is slowed down. Can be done. Generation of static electricity can be reduced by slowing the peeling operation of the cover tape 15.

  By the way, in the component mounting machine 10 in which the plurality of tape feeders 12 are set, since the feeder stop time is different for each tape feeder 12, the cover tape 15 of the component supply tape 13 is exposed to dry air near the peeling position. The time also differs for each tape feeder 15.

  Therefore, in the component mounter 10 in which a plurality of tape feeders 12 are set, the feeder stop time is measured for each tape feeder 13, and the use of the component supply tape 13 is used for each tape feeder 13 based on the feeder stop time and humidity. The permission / prohibition is managed. In this way, the tape feeder 12 set in the component mounter 10 is monitored for whether or not a trouble due to static electricity is likely to occur, and the tape that is likely to cause a trouble due to static electricity. The use of the component supply tape 13 can be prohibited only for the feeder 12.

  In this embodiment, when the measured feeder stop time is longer than a predetermined time and the humidity detected by the humidity sensor 22 is lower than the predetermined humidity, the use of the component supply tape 13 mounted on the tape feeder 12 is prohibited. I am doing so. Here, the “predetermined time” and the “predetermined humidity” may be a predetermined value (fixed value) determined in advance, or may be changed depending on the material, the type of component, and the like of the component supply tape 13. This is because the rate of occurrence of defects due to static electricity changes depending on the material, component type, and the like of the component supply tape 13.

  By the way, among the component supply tapes 13 of a plurality of component types that can be mounted on the tape feeder 12, there are electronic components (for example, large components) that are free from problems caused by static electricity that occurs when the cover tape 15 is peeled off. . It is not necessary to manage permission / prohibition of use of the component supply tape 13 of a component type that does not cause a problem due to static electricity.

  Therefore, in the present embodiment, among the component supply tapes 13 of a plurality of component types that can be mounted on the tape feeder 12, the component supply tape 13 of a component type that does not cause trouble due to static electricity that occurs when the cover tape 15 is peeled off is Only the component feeder tape 13 of a component type that is not subject to management and may cause a malfunction due to static electricity is managed, and only the tape feeder 12 having the component supply tape 13 of the component type to be managed is mounted. The permission / prohibition of the use of the component supply tape 13 is managed, and the use of the component supply tape 13 is permitted for the component supply tape 13 of a component type that is not a management target. In this way, it is not necessary to manage the component supply tape 13 of a component type that does not cause a problem due to static electricity, and the processing load required for managing the component supply tape 13 can be reduced accordingly.

  The management of the component supply tape 13 of the tape feeder 12 of the present embodiment described above is executed as follows according to the tape feeder management program of FIGS. 3 and 4 by the control device 31 (or host computer 41) of the component mounter 10. Is done. When this program is started, first, in step 101, the operator waits until the production start button 39 (see FIG. 2) is pressed. Thereafter, when the production start button 39 is pressed, the process proceeds to step 102 to start production. As a result, the circuit board is carried into the component mounting machine 10, the cover tape 15 is peeled off from the front end side of the component supply tape 13 by the tape feeder 12, and the electronic component in the component supply tape 13 is exposed to supply the component. The tape 13 is sent to the component suction position, and the cover tape 15 is peeled off from the upper surface of the component supply tape 13 before the component suction position to expose the electronic components in the carrier tape 16, and the carrier tape 16 is exposed at the component suction position. The electronic component is sucked by the suction nozzle of the component mounting machine 10 and mounted on the circuit board.

  Thereafter, the process proceeds to step 103 and waits until the production is stopped or the production of one sheet is completed (substrate delivery). Thereafter, when the production is stopped or the production of one sheet is completed (substrate delivery), the process proceeds to step 104 to determine whether there is a tape feeder 12 to which the component supply tape 13 of the component type to be managed exists. . Here, the component supply tape 13 of the component type to be managed is a component supply tape 13 of a component type that may cause a malfunction due to static electricity that occurs when the cover tape 15 is peeled from the component supply tape 13. . Therefore, if it is determined in step 104 that there is no tape feeder 12 to which the component supply tape 13 of the component type to be managed exists, there is no problem due to static electricity that occurs when the cover tape 15 is peeled off. After the determination, the process returns to step 103 and waits until the next production is stopped or one sheet production is completed (substrate delivery).

  On the other hand, if it is determined in step 104 that there is a tape feeder 12 to which the component supply tape 13 of the component type to be managed exists, the process proceeds to step 105 and the component supply tape 13 of the component type to be managed is obtained. For each tape feeder 12 to which is attached, the feeder stop time for waiting in a stopped state is measured. Then, in the next step 106, the humidity sensor 22 detects the humidity of the air inside the component mounting machine 10 where the main body side portion of the tape feeder 12 (near the peeling position of the cover tape 15) is present. Then, it is determined whether or not the humidity detected by the humidity sensor 22 is equal to or lower than a predetermined humidity. Here, the “predetermined humidity” corresponds to a lower limit value of a humidity range in which trouble due to static electricity that occurs when the cover tape 15 is peeled off, and may be a predetermined constant value (fixed value) or a component. You may make it change with the material of the supply tape 13, a component kind, etc. FIG. This is because the rate of occurrence of defects due to static electricity changes depending on the material, component type, and the like of the component supply tape 13.

  If it is determined in step 107 that the detected humidity is not equal to or lower than the predetermined humidity, it is determined that no trouble is caused by static electricity, and the process proceeds to step 109, where the component supply tape mounted on all the tape feeders 12 13 is permitted and the production is continued, and the process returns to the above-described step 103 and waits until the next production is stopped or the one-sheet production is completed (substrate delivery).

  On the other hand, if it is determined in step 107 that the detected humidity is equal to or lower than the predetermined humidity, the process proceeds to step 108, and the tape feeder 12 in which the component supply tape 13 of the component type to be managed is mounted. Then, it is determined whether or not there is a tape feeder 12 whose feeder stop time is equal to or longer than a predetermined time. Here, the “predetermined time” corresponds to the minimum value of the feeder stop time at which trouble due to static electricity that occurs when the cover tape 15 is peeled off, and may be a predetermined constant value (fixed value). The material may be changed depending on the material of the component supply tape 13 or the component type. This is because the rate of occurrence of defects due to static electricity changes depending on the material, component type, and the like of the component supply tape 13.

  If it is determined in step 108 that there is no tape feeder 12 for which the feeder stop time has reached a predetermined time or more, it is determined that there is no problem due to static electricity, and the process proceeds to step 109, where all the tape feeders 12 are set. Production is continued by permitting the use of the mounted component supply tape 13, and the process returns to step 103, and waits until the next production is stopped or one sheet production is completed (substrate delivery).

  On the other hand, if it is determined in step 108 that there is a tape feeder 12 whose feeder stop time is equal to or longer than the predetermined time, it is determined that a problem due to static electricity is likely to occur, and FIG. In step 110, the use of the component supply tape 13 mounted on the tape feeder 12 whose feeder stop time has reached a predetermined time or more is prohibited. In the next step 11, the feeder stop time has become a predetermined time or longer. The operation of sucking the electronic component from the tape feeder 12 to the suction nozzle is stopped to prevent a component suction failure caused by static electricity.

  Thereafter, the process proceeds to step 112, where the component supply tape of the tape feeder 12 is in a state in which a malfunction due to static electricity is likely to occur due to a warning display or sound from the display device 33 of the component mounter 10 or the display device of the host computer 41. The operator is warned that 13 is present and urged to replace the component supply tape 13. Thereafter, the process proceeds to step 113 and waits until the operator replaces the component supply tape 13.

  Thereafter, when the component supply tape 13 is replaced, the process proceeds to step 114, and whether or not the reel 14 of the replaced component supply tape 13 is the same as before replacement (that is, the component supply tape once removed by the operator). As a result, if it is determined that the reel 14 of the replaced component supply tape 13 is the same as that before the replacement, the process proceeds to step 116 to mount the component. An error is displayed on the display device 33 of the machine 10, the display device of the host computer 41, etc., and the operator is urged to replace the component supply tape 13 again. Thereafter, the process returns to step 113, and the above-described processing is re-executed.

  On the other hand, if it is determined in step 114 that the reel 14 of the replaced component supply tape 13 is not the same as that before the replacement, the process proceeds to step 115 to resume production. Thereafter, the processing after step 103 in FIG. 3 is re-executed.

  In the present embodiment described above, the feeder stop time during which the tape feeder 12 is stopped is measured, the humidity of the air in which the tape feeder 12 is present is detected, and the tape feeder 12 is determined based on the feeder stop time and humidity. Since the permission / prohibition of use of the mounted component supply tape 13 is managed, both the time during which the cover tape 15 of the component supply tape 13 is exposed to dry air near the peeling position and the humidity of the air In consideration of the above, when the cover tape 15 is peeled from the component supply tape 15, it is monitored whether or not the trouble due to static electricity is likely to occur, and when the trouble due to static electricity is likely to occur. It becomes possible to prohibit the use of the component supply tape 13, and the time during which the component supply tape 13 is exposed to dry air becomes longer. It can effectively prevent the problems caused by the.

  In this embodiment, when the measured feeder stop time is equal to or longer than a predetermined time and the humidity detected by the humidity sensor 22 is equal to or lower than the predetermined humidity, the component supply tape 13 mounted on the tape feeder 12 is used. However, the present invention is not limited to this, and is mounted on the tape feeder 12 when the measured feeder stop time exceeds a predetermined time set according to the humidity detected by the humidity sensor 22. The use of the component supply tape 13 may be prohibited. In this case, static electricity is more likely to occur when the cover tape 15 is peeled from the component supply tape 13 as the humidity of the air is lower (that is, the air is dried). The feeder stop time (predetermined time) until the use of the component supply tape 13 is prohibited may be set to a short time.

  Further, in the present embodiment, considering that the sealing degree of the component mounting machine 10 is relatively high and the difference in humidity between the inside and outside of the component mounting machine 10 is relatively large, a humidity sensor is provided inside the component mounting machine 10. 22 is installed to detect the humidity of the air inside the component mounter 10 where the main body side portion of the tape feeder 12 (near the peeling position of the cover tape 15) is present, which causes a problem due to static electricity. The humidity of the air in the vicinity of the peeling position of the cover tape 15 can be detected with high accuracy, and it can be accurately monitored whether or not a malfunction due to static electricity is likely to occur. However, when the difference in humidity between the inside and outside of the component mounter 10 is relatively small, a humidity sensor 22 is installed outside the component mounter 10 so that the air outside the component mounter 10 is removed. Humidity may be detected.

  Further, in this embodiment, among the component supply tapes 13 of a plurality of component types that can be mounted on the tape feeder 12, only the component supply tape 13 of a component type that may cause a failure due to static electricity is managed and managed. Although the permission / prohibition of use of the component supply tape 13 is managed only for the tape feeder 12 to which the component supply tape 13 of the target component type is mounted, all the tape feeders 12 set in the component mounter 10 are managed. The permission / prohibition of use of the component supply tape 13 may be managed.

  In the present embodiment, among the plurality of tape feeders 12 set in the component mounting machine 10, the component suction is performed only for the tape feeder 12 that is determined to be prohibited from using the component supply tape 13 based on the feeder stop time and humidity. Although it stopped, you may make it stop component adsorption | suction of all the tape feeders 12 set to the component mounting machine 10, and the structure which sets the tape feeder 12 to the both sides of the component mounting machine 10 Then, the component suction of the side tape feeder 12 on which the tape feeder 12 determined to be prohibited from using the component supply tape 13 is set may be stopped. Further, in a configuration in which a plurality of component mounting machines 10 are arranged on the production line, when any of the component mounting machines 10 is determined to be prohibited from using the component supply tape 13 based on the feeder stop time and humidity. In addition, all the component mounting machines 10 in the production line may be stopped.

  In addition, it goes without saying that the present invention can be implemented with various modifications within a range not departing from the gist, such as appropriately changing the configuration of the component mounter 10 and the configuration of the tape feeder 12.
