Description

  Whether or not the combination of the component for adjusting the characteristic and the component to be adjusted is correct when there is a component for adjusting the characteristic in combination with the component for adjusting the characteristic among the plurality of components mounted on the circuit board. It is invention regarding the feeder components collation system which judges.

  Among the components mounted on the circuit board, there may be a component that needs to adjust the characteristic variation. Since the characteristics of such parts can be adjusted by combining with characteristics adjustment parts (for example, passive parts such as resistors, coils, capacitors, etc.), Patent Document 1 (Japanese Patent Laid-Open No. 2005-136023) shows characteristic variations. The characteristics of the component to be adjusted (LED) are measured with a measuring instrument, and the optimum characteristic adjustment component (resistor component) to be combined with the component to be adjusted is specified, and a plurality of feeders set on the component mounting machine The feeder for supplying the optimum characteristic adjustment component is selected from among the components, and the characteristic of the component to be adjusted mounted on the circuit board is adjusted by the optimum characteristic adjustment component.

Japanese Patent Laid-Open No. 2005-136023

  By the way, since the allowable range of the characteristics of the characteristic adjustment parts that can be combined with the adjusted parts also varies, the characteristic adjustment parts that are combined with the adjusted parts every time the feeder that supplies the adjusted parts is replaced. It is necessary to confirm that the characteristics are within the allowable range. Therefore, in the above-mentioned Patent Document 1, a data table in which the optimum resistance value of the resistance component, which is a characteristic adjustment component, is created in advance for each luminance rank of the LED component, which is the component to be adjusted, on the circuit board. By referring to the data table for each LED component to be mounted and selecting a feeder that supplies the resistor component having the optimum resistance value, the resistor component having the optimum resistance value is mounted on the circuit board in combination with the LED component. I have to.

  However, when an operator sets a resistance component feeder on a component mounter, there is a possibility that a human error in setting a resistor component feeder with an incorrect resistance value on the component mounter may occur. When such an operation error occurs, there is a problem that a resistance component having an incorrect resistance value is mounted on the circuit board, and a defective mounting board is produced.

  Therefore, the problem to be solved by the present invention is to provide a feeder component verification system that can prevent the production of defective mounting boards due to human error.

  In order to solve the above-mentioned problem, the invention according to claim 1 is characterized in that a part for adjusting characteristics in combination with a part for characteristic adjustment (hereinafter referred to as “adjusted part”) among a plurality of parts mounted on a circuit board. A feeder component verification system that determines whether or not a combination of a component for characteristic adjustment and the component to be adjusted is correct, if present, in which identification information of a component to be supplied is recorded or stored. Component identification information recording unit, data on the allowable range of the characteristic adjustment component that can be combined with the component to be adjusted mounted on the circuit board (hereinafter referred to as “combinable component characteristic data”), and the characteristic adjustment component A database in which the characteristic data of each part is registered in association with the identification information of each part, identification information reading means for reading the part identification information from the part identification information recording unit, and the identification Based on the identification information of the part read by the information reading means, it is determined whether the part is a characteristic adjustment part or a part to be adjusted, and if it is determined as a characteristic adjustment part, the characteristic adjustment part is read from the database. If the characteristic data of the part is acquired and determined to be an adjusted part, based on the data acquired by the data acquisition means for acquiring the part characteristic data that can be combined with the adjusted part from the database, and the data acquired by the data acquisition means By determining whether the characteristic of the characteristic adjustment component is within an allowable range of the characteristic of the characteristic adjustment component that can be combined with the adjusted component, the characteristic adjustment component and the adjusted component And a combination determination unit that determines whether the combination is correct or not.

  In this configuration, the characteristic data of the component for characteristic adjustment and the component characteristic data that can be combined with the component to be adjusted are acquired from the database, and the characteristic adjustment component can be combined with the component to be adjusted. Because it is possible to automatically determine whether the combination of the part for adjusting the characteristic and the part to be adjusted is correct by determining whether or not it is within the allowable range of the characteristic, the operator can adjust the part for adjusting the characteristic. When setting the feeder to the component mounter, even if the component feeder for the characteristic adjustment with the wrong characteristics is set to the component mounter, the combination of the component for characteristic adjustment and the component to be adjusted is automatically determined. Thus, it can be determined in advance that the part is a component for adjusting characteristics with wrong characteristics, and it is possible to prevent the production of defective mounting boards due to human error. Moreover, since it is not necessary to previously define a combination of the characteristic adjustment component and the component to be adjusted, there is an advantage that the work load can be reduced.

  In this case, as described in claim 2, when the combination determination unit determines that the component is a characteristic adjustment component based on the identification information of the component read by the identification information reading unit, From the parts to be adjusted for which data was acquired, select the part to be adjusted for which the characteristic adjustment part to be combined has not been determined, and whether the combination of the selected part to be adjusted and the part for characteristic adjustment to be judged is correct It may be determined whether or not.

  In this case, as an adjusted component, various active components (for example, transistors, diodes, LEDs, ICs, operational amplifiers, etc.) whose characteristics can be adjusted in combination with components for adjusting characteristics (for example, passive components such as resistors, coils, capacitors, etc.) However, if the present invention is implemented with the component to be adjusted as the LED component and the component for adjusting the characteristic as the resistance component as in claim 3, the characteristic variation of the LED component widely used in various display devices is surely obtained. Can be adjusted.

  According to a fourth aspect of the present invention, when the combination determination means determines that the combination of the characteristic adjustment component and the component to be adjusted is incorrect, it notifies the operator of at least one of display and sound. It is good to do. In this way, when the combination of the component for characteristic adjustment and the component to be adjusted is wrong, the operator can be prompted to replace the feeder of the component for characteristic adjustment.

FIG. 2 is a diagram conceptually showing the component information registered in the database. FIG. 3 is a flowchart showing the flow of processing in the first half of the feeder part verification program. FIG. 4 is a flowchart showing the flow of processing in the latter half of the feeder component verification program.

Hereinafter, an embodiment embodying a mode for carrying out the present invention will be described.
First, the overall configuration of the system will be schematically described with reference to FIG.
A production management computer 11 (server) for managing production of a component mounting line, an ID input personal computer 12, a component mounting machine 13, and the like are connected via a network. In addition to one or a plurality of component mounting machines 13, a printing device, a flux application device, an inspection device, a reflow furnace, and the like are arranged in the component mounting line.

  In the database used by the production management computer 11, in addition to the types and specifications of the components used in the component mounting machine 13, the resistance of the resistance component which is a characteristic adjustment component which can be combined with the LED component which is the adjusted component The component information (see FIG. 2) including data on the allowable range of the value and data on the variation range of the resistance value of the resistive component is registered in association with identification information (hereinafter referred to as “component ID”) of each component.

  The ID input personal computer 12 includes an input device 14 such as a keyboard, a mouse, and a touch panel, a display device 15 such as a liquid crystal display and a CRT, and a bar that optically scans and reads code information such as a barcode and a two-dimensional code. A reader 16 (identification information reading means) such as a code reader is provided.

  On the other hand, a plurality of tape feeders 17 (feeders) are detachably set in the component mounter 13, and components supplied from the tape feeders 17 are sucked by suction nozzles and mounted on a circuit board. A tape reel 18 around which a component supply tape is wound is detachably set in each tape feeder 17. The tape reel 18 is provided with a component ID code 19 (component identification information recording unit) such as a barcode or a two-dimensional code in which identification information (component ID) of the component in the component supply tape is recorded. The component ID is read from the component ID code 19 by the reader 16, and the component ID is transmitted from the ID input personal computer 12 to the production management computer 11.

  The production preparation procedure is as follows. First, an operator selects a tape reel 18 of a part to be used from among the tape reels 18 in stock and sets the tape reel 17 on the tape feeder 17. At this time, before setting the tape reel 18 on the tape feeder 17, the operator scans the component ID code 19 of the tape reel 18 using the reader 16, and reads the read component ID from the ID input personal computer 12. After transmitting to the production management computer 11, the tape reel 18 is set on the tape feeder 17. Note that the part ID code 19 of the tape reel 18 may be read after the tape reel 18 is set on the tape feeder 17.

  The production management computer 11 reads the component type information corresponding to the component ID read by the reader 16 from the database by executing a feeder component verification program shown in FIGS. 3 and 4 to be described later. If it is determined whether it is a component or LED component, and it is determined to be a resistance component, data on the variation range of the resistance value of the resistance component is obtained from the database. If it is determined to be an LED component, it is combined with the LED component from the database. It functions as a data acquisition means for acquiring allowable range data of resistance values of resistance components (hereinafter referred to as “component characteristics data that can be combined with LED components”), and the resistance range variation range of the resistance components acquired from the database. Resistance value of resistance component based on data and component characteristic data that can be combined with LED component It also functions as a combination determination unit that determines whether the combination of the resistor component and the LED component is correct by determining whether the variation range is within the allowable range of the resistance value of the resistor component that can be combined with the LED component. To do. Specifically, when the production management computer 11 determines that the component is a resistance component based on the component ID read by the reader 16, the resistor to be combined is selected from the components to be adjusted that have acquired the component characteristic data that can be combined so far. Select an LED component that has not been determined, and determine whether the combination of the selected LED component and the resistance component to be determined is correct. As a result, the combination of the LED component and the resistance component to be determined is incorrect. When it is determined that it is a resistor component that cannot be combined with an LED component, the operator is notified of at least one of display and sound, and the tape feeder 17 of the resistor component that cannot be combined is replaced. Encourage workers.

  The above-described feeder part collation process of the present embodiment is executed by the production management computer 11 as follows according to the feeder part collation program of FIGS. When the feeder part collation program of FIGS. 3 and 4 is started, first, at step 101, it is determined whether or not the production management computer 11 has received the part ID read by the reader 16 from the part ID code 19. If the component ID has not been received yet, it waits until the component ID is received.

  Thereafter, when the component ID read by the reader 16 is received, the process proceeds to step 102, where it is determined whether or not the component with the component ID is an LED component based on the component information registered in the database. As a result, if it is determined that it is an LED component, the process proceeds to step 103, and data on the allowable range of the resistance value of the resistor component that can be combined with the LED component (data on the variation range of the resistance value of the resistor component) from the database. Is stored in the memory of the production management computer 11, the process returns to step 101, and the determination process described above is executed again.

  On the other hand, if it is determined in step 102 that the component is not an LED component, the process proceeds to step 104 to determine whether or not the component with the component ID is a resistive component. If both “No” is determined in Step 102 and Step 104 described above, that is, if the component does not correspond to any of the LED component and the resistive component, it is necessary to determine the combination of the LED component and the resistive component. Therefore, the process returns to step 101 and the determination process described above is executed again.

  If it is determined in step 104 that the component with the component ID is a resistance component, the process proceeds to step 105, where data of the variation range of the resistance value of the resistance component is acquired from the database and stored in the memory. Thereafter, the process proceeds to step 106 in FIG. 4, and the resistive component to be combined has not been determined from among the LED components that have acquired the combinable component characteristic data (data on the allowable range of the resistance value of the combinable resistive component). After selecting one LED component, the process proceeds to step 107, where the resistance value variation range data of the resistance component is compared with the LED component combinationable component characteristic data. It is determined whether or not the resistance values of the resistance components that can be combined are within an allowable range. In addition, when there are a plurality of resistance components for which the LED component to be combined is not determined, the resistance within which the variation range of the resistance value falls within the allowable range of the resistance value of the resistance component that can be combined with the LED component. What is necessary is just to determine whether components exist.

  In step 107 above, the variation range of the resistance value of the resistance component is within the allowable range of the resistance value of the resistance component that can be combined with the LED component (the variation range of the resistance value is the resistance value of the resistance component that can be combined with the LED component). If it is determined that there is a resistance component that falls within the allowable range, the process proceeds to step 108, and the resistance component is a resistance component to be combined with the determination target LED component (that is, the resistance component and the determination target LED component). Is determined to be correct). Thereafter, the process proceeds to step 109, where it is determined whether or not the resistor parts to be combined are determined for all the LED parts to be mounted on the circuit board. Returning to 101, the determination process described above is executed again.

  On the other hand, if it is determined in step 109 that the resistance components to be combined have been determined for all the LED components mounted on the circuit board, it is determined that all the feeder component verification processes have been completed, and the program is terminated.

  In step 107, the resistance value variation range of the resistance component is not within the allowable range of the resistance value of the resistance component that can be combined with the LED component (the resistance value variation range is the resistance of the resistance component that can be combined with the LED component). If it is determined that there is no resistance component that falls within the allowable range of values), the process proceeds to step 110 to determine whether or not there remains an LED component for which a resistance component to be combined has not been determined. As a result, if it is determined that there are remaining LED components for which the resistance component to be combined is not determined, the process returns to step 106 to select one LED component for which the resistance component to be combined is not determined, and the determination process of step 107 is performed. Try again.

  Thereafter, if it is determined in step 110 that there is no LED component for which the resistor component to be combined has not been determined, the process proceeds to step 111, and any LED component cannot be combined (resistor component and LED component). Is determined to be incorrect). In this case, the process proceeds to step 112, in which the worker is notified that at least one of the display and the sound is a resistance component that cannot be combined with the LED component, and the worker replaces the tape feeder 17 of the resistance component that cannot be combined. Prompt. Thereafter, the process returns to step 101 in FIG. 3 and the above-described determination process is executed again.

  According to the embodiment described above, the resistance value variation range data of the resistor component and the LED component combinationable component characteristic data are obtained from the database, and the resistance component variation range of the resistance component can be combined with the LED component. Since it is possible to automatically determine whether the combination of the resistance component and the LED component is correct by determining whether the resistance value of the resistance component is within an allowable range, the operator can determine whether the resistance component tape feeder is correct. When setting 17 to the component mounting machine 13, even if the tape feeder 17 of the resistance component having the wrong resistance value is set to the component mounting machine 13, it is wrong due to automatic determination of the combination of the resistance component and the LED component. It can be determined in advance that the resistance component is a resistance component, and production of defective mounting boards due to human error can be prevented in advance. Moreover, since it is not necessary to previously define the combination of the resistor component and the LED component, there is an advantage that the work load can be reduced.

  In this embodiment, the component ID is recorded as a bar code, a two-dimensional code, etc., but the component ID is stored in an electronic tag (also called RF tag, wireless tag, IC tag, radio wave tag, etc.), However, the reader may read the component ID from the electronic tag.

  In the present embodiment, the component ID itself is read by the reader 16, but related information between the feeder ID and the component ID may be created in advance, and the feeder ID may be read by the reader 16. That is, the component identification information in the present invention is not limited to the component ID, but may be information associated with the component ID.

  In Steps 103 and 106, the combination of the resistor component and the LED component is selected. However, when the resistor component or the LED component to be combined is determined in advance according to the arrangement position of each component, based on the reading position of the reader 16. The resistance component or the LED component to be combined may be specified.

In addition, the characteristic adjustment component and the component to be adjusted are not limited to the resistor component and the LED component, and active components such as transistors, diodes, ICs, operational amplifiers, etc. using passive components such as coils and capacitors as characteristic adjustment components. You may make it adjust the characteristic of components.
Further, the feeder that supplies components to the component mounting machine is not limited to a tape feeder, and a tray feeder, a bulk feeder, a stick feeder, or the like may be used.

  In addition, the present invention is not limited to the configuration in which the determination of the combination of the part for adjusting the characteristic and the part to be adjusted is executed by the production management computer 11, and the control unit of each component mounter 13 The combination with the component to be adjusted may be determined. In this case, a reader 16 that reads the component ID may be provided in each component mounter 13 and the like. Needless to say, it can be implemented with changes.
