[0004] By the way, in such a light-emitting unit, in order to adjust the luminance and color of each LED more precisely and emit light with uniform luminance and color, it may be mounted together with a resistor. However, in Patent Document 1 described above, since the combination with the resistor is not considered, further improvement is required.

[0005] The main object of the present disclosure is to appropriately suppress the variation in the light-emitting state among LEDs in a light-emitting unit in which a plurality of LEDs are mounted together with resistors on a unit substrate.

[0008] In the manufacturing method of the light-emitting unit of the present disclosure, management data that defines a plurality of combinations of one master LED, slave LEDs selected according to the luminance and color of the other LEDs including the master LED, and slave resistors selected according to the luminance and color of the LEDs is created, and based on any of the combinations defined in the management data, the respective component supply units are set on the mounter. As a result, it becomes possible to suppress variations in the luminance and color of the master LED and the slave LEDs by combining them with appropriate resistors. For this reason, in a light-emitting unit in which a plurality of LEDs are mounted together with resistors, variations in the light-emitting state between the LEDs can be appropriately suppressed.

Embodiments for Carrying Out the Invention

[0010] Next, embodiments for carrying out the present disclosure will be described with reference to the drawings.

[0011] FIG. 1 is a configuration diagram showing an outline of the configuration of the component mounting system 10 of the present embodiment, FIG. 2 is a configuration diagram showing an outline of the configuration of the mounter 20, and FIG. 3 is a configuration diagram related to the control of the component mounting system 10. In FIGS. 1 and 2, the left-right direction is the X direction, the front-rear direction is the Y direction, and the up-down direction is the Z direction.

[0012] As shown in Fig. 1, the component mounting system 10 includes a printer 12, a printing inspection machine 14, a plurality of mounters 20, a mounting inspection machine 16, and a management device 30. The printer 12 prints on a substrate S (see Fig. 2) by pressing solder into pattern holes formed in a screen mask. The printing inspection machine 14 inspects the state of the solder printed by the printer 12. A plurality of mounters 20 are arranged along the conveyance direction (X direction) of the substrate S to mount components on the substrate S. In Fig. 2, four mounters 20 are illustrated as an example. The mounting inspection machine 16 inspects the mounting state of the components mounted on the substrate S by the mounters 20. The management device 30 manages the entire component mounting system 10. The printer 12, the printing inspection machine 14, the plurality of mounters 20, and the mounting inspection machine 16 are installed side by side in this order in the conveyance direction of the substrate S to form a production line. Note that the component mounting system 10 may further include a reflow machine or the like that performs a reflow process on the substrate S on which components are mounted, and the mounting inspection machine 16 may be arranged on the downstream side of the reflow machine.

[0013] As shown in Fig. 2, the mounter 20 includes a substrate conveyance device 21 that conveys the substrate S in the X direction, a head 23 having a suction nozzle that sucks components supplied by a plurality of feeders 22, a head movement mechanism 24 that moves the head 23 in the XY directions, and a display 25 such as an LCD (see Fig. 1). The feeder 22 is, for example, a tape feeder that supplies components by feeding out a tape in which components are accommodated at a predetermined pitch, and is detachably set in a plurality of slots of the mounter 20 so as to be able to supply components. Further, the mounter 20 includes a mounting control device 28 (see Fig. 3) that is composed of a well-known CPU, ROM, RAM, etc. and controls the entire device. The mounting control device 28 outputs control signals to the substrate conveyance device 21, the feeder 22, the head 23, the head movement mechanism 24, the display 25, etc.

[0014] As shown in FIG. 3, the management device 30 is composed of a well-known CPU 30a, ROM 30b, HDD 30c, RAM 30d, etc., and includes an input device 32 such as a keyboard and a mouse, and a display 34 such as an LCD. The management device 30 is communicably connected to a control device (not shown) of the printing machine 12, the printing inspection machine 14, and the mounting inspection machine 16, and the mounting control device 28, and receives information regarding the working status from each control device, or transmits a work instruction such as a job including information regarding the work. Note that the mounting control device 28 can display necessary information on the display 25 based on the information received from the management device 30. Further, a well-known printer 36 is connected to the management device 30. The printer 36 prints and outputs work instructions for the operator on paper based on a print instruction from the management device 30.

[0015] Here, FIG. 4 is an explanatory diagram showing an example of the multi-sided extraction substrate S1. As shown in the figure, the multi-sided extraction substrate S1 as the substrate S is an assembled substrate including a plurality of unit substrates S2 (sub-substrates). In the multi-sided extraction substrate S1 of the present embodiment, a large number of pairs of unit substrates S2 having the same shape (substantially L-shaped) inverted by 180 degrees are arranged vertically and horizontally. Each unit substrate S2 is separated by a dividing groove. Therefore, the multi-sided extraction substrate S1 can easily separate each unit substrate S2 along the dividing groove by pressing each unit substrate S2. Note that each unit substrate S2 is also referred to as a board, and the number described at the end thereof indicates an identification number.

[0016] In each unit substrate S2 of the present embodiment, for example, two LEDs 2 (2a, 2b) and one resistor 4 are mounted on the mounting machine 20 as components respectively to form one light-emitting unit. Note that the number of LEDs 2 mounted on each unit substrate S2 is not limited to two, and a plurality of them may be mounted, and the number of resistors is not limited to one, and a plurality of them may be mounted. Each mounting machine 20 collects the LEDs 2 and the resistors 4 from the feeder 22 by the head 23 and mounts them on each unit substrate S2 according to the mounting order determined by the job which is a work instruction transmitted from the management device 30.

[0017] Here, there are variations in brightness, color, etc. among the LEDs 2 due to individual differences in manufacturing. Therefore, when manufacturing a light-emitting unit by mounting a plurality of LEDs 2 on the unit substrate S2, the LEDs 2 to be mounted on the same unit substrate S2 are selected so that the brightness and color of each LED 2 are as uniform as possible within the unit substrate S2. However, if the brightness and color of each LED 2 mounted on the same unit substrate S2 are strictly controlled, the number of LEDs 2 to be mounted will decrease, and the number of work-in-progress products will increase. On the other hand, by using resistors 4 with different resistance values, the current value flowing through the LED 2 can be adjusted to change the brightness and color. That is, by combining appropriate resistors 4 according to the target brightness and color of the LED 2, the brightness and color of each LED 2 can be made uniform. Therefore, in the present embodiment, a plurality of combinations of the LED 2 and the resistor 4 that can be mounted on the same unit substrate S2 are determined so that the brightness and color of each LED 2 mounted on the same unit substrate S2 are substantially uniform, registered in the management data, and one of the plurality of combinations is selected as the mounting target and mounted on the same unit substrate S2. Note that the information indicating the brightness and color of the LED 2 is called a characteristic class.

[0018] FIG. 5 is a flowchart showing an example of a light-emitting unit manufacturing process. In the light-emitting unit manufacturing process, the CPU 30a of the management device 30 first creates management data defining combinations of the LED 2 and the resistor 4 that can be mounted on the same unit substrate S2 (S100).

[0019] FIG. 6 is an explanatory diagram showing an example of management data. In the present embodiment, one of the two LEDs 2 (for example, LED 2a) is used as the master LED, the other (for example, LED 2b) is used as the slave LED, and the resistor 4 is managed as the slave resistor. In the following description, they are referred to as the master LED, the slave LED, and the slave resistor. The code of the slave LED and the characteristic class indicating the luminance and color of the master LED are determined according to the part name code of the master LED. That is, the code and the characteristic class of the slave LED depend on the code and the characteristic class of the master LED. In addition, the code indicating the type (resistance value) of the slave resistor is determined according to the codes and the characteristic classes of the master LED and the slave LED. In the management data of FIG. 6, a plurality of combinations (a total of 12 combinations from No. 1 to 12) in which the code and the characteristic class of the master LED, the code and the characteristic class of the slave LED, and the code of the slave resistor are associated are determined. For example, in the characteristic class "793.305-00", "793" indicates the luminance, "305" indicates the voltage, and "00" indicates the color.

[0020] Also, in FIG. 6, a plurality of combinations of slave LEDs and slave resistors corresponding to the master LED with the code "793.304-00" are illustrated. Combinations No. 1 to 3 are combinations in which the characteristic class of the master LED corresponds to "793.305-00". In all of Combinations No. 1 to 3, the code of the slave LED is "793.673-05", but the characteristic class of the slave LED and the code of the slave resistor are different. Combination No. 1 is a combination of a slave LED whose characteristic class is any one from "793.060-50" to "793.060-61" (the end is any one of "50" to "61", the same applies hereinafter) and a slave resistor with the code "733.415-82". Combination No. 2 is a combination of a slave LED whose characteristic class is any one from "793.060-62" to "793.060-73" and a slave resistor with the code "733.416-01". Combination No. 3 is a combination of a slave LED whose characteristic class is any one from "793.060-74" to "793.060-85" and a slave resistor with the code "733.416-13". Since the other Combinations No. 4 to 12 are also defined in the same way, the description is omitted. Note that in FIG. 6, slave LEDs with the same code are illustrated, but slave LEDs with different codes may also be included. Also, similar to the master LED and the slave LED, the code of the slave resistor may be divided into a code indicating the part name and a characteristic class indicating the resistance value.

[0021] Next, the CPU 30a creates a job for mounting each component such as the master LED, slave LED, and slave resistor on the multi-sided mounting substrate S1 (each unit substrate S2) (S110). In the job, information such as which mounter 20 to mount each component on, the mounting position, and the mounting order is determined. Also, information on which slot of each mounter 20 to set the feeder 22 of each component is determined. When the CPU 30a creates the management data and job in this way, it prints and outputs a management data sheet for presenting the management data to the operator using the printer 36 (S120), and transmits the job to each mounter 20 (S130). Note that since the same content as the management data in FIG. 6 is printed on the management data sheet, the illustration is omitted. The operator prepares to set the feeder 22 containing the master LED, slave LED, and slave resistor based on any combination while referring to the printed management data sheet for each mounter 20. Also, the CPU 30a executes a guidance display process for displaying on the display 25 of each mounter 20 the feeder 22 to be set in each mounter 20 and the destination slot for guidance to the operator (S140).

[0022] FIG. 7 is a flowchart showing an example of the guidance display process. FIGS. 8 to 10 are explanatory diagrams showing an example of the state of the guidance display, and the four mounters 20 are referred to as mounters 20(1) to 20(4). The guidance display process is jointly executed by the CPU 30a of the management device 30 and the mounting control device 28 of each mounter 20, but will be described mainly with the CPU 30a. In the guidance display process, first, the CPU 30a instructs the setting of the feeder 22 of the master LED by causing the code of the master LED to be displayed on the display 25 of the mounter 20 (S200), and waits for the feeder 22 to be set (S210). For example, as shown in FIG. 8, the mounter 20 on which the feeder 22 of the master LED is to be set is the mounter 20(1). In S200, the display 25 of the mounter 20(1) displays the slot No. of the destination for setting the feeder 22 of the master LED and the code of the master LED.

[0023] When the feeder 22 of the master LED is set in S210, the CPU 30a acquires the code and characteristic class of the master LED accommodated in the feeder 22 as the component information of the set feeder 22 through communication with the mounting machine 20(1) (S220). Next, the CPU 30a determines whether the master LED is correctly set based on the acquired code of the master LED (S230). If the acquired code of the master LED matches the code shown in the guidance display, the CPU 30a determines that the master LED is correctly set. If the CPU 30a determines that the master LED is not correctly set, it causes the mounting machine 20(1) to notify an error (S240) and returns to S200. In S240, it is notified that the code of the LED (here, the master LED) of the set feeder 22 is incorrect, and the guidance display is performed to return to S200 and set the correct feeder 22.

[0024] On the other hand, when the CPU 30a determines in S230 that the master LED is correctly set, it selects a slave LED from the characteristic class of the master LED with reference to the management data (S250). For example, in FIG. 9, it shows a case where the feeder 22 set in the mounting machine 20(1) accommodates a master LED with a code of "793.304-00" and a characteristic class of "793.305-01". This master LED corresponds to combination Nos. 4 to 6 of the management data (see FIG. 6). Therefore, in S250, the CPU 30a selects a slave LED with a code of "792.673-05" and a characteristic class of any one of "793.060-50" to "793.060-85".

[0025] Subsequently, the CPU 30a causes the code and characteristic class of the selected slave LED to be displayed on the display 25 of the mounter 20, thereby instructing the setting of the feeder 22 for the slave LED (S260), and waits for the feeder 22 to be set (S270). For example, as shown in FIG. 9, the mounter 20 for which the feeder 22 of the slave LED is to be set is the mounter 20(2). In S260, the slot No. where the feeder 22 of the slave LED is to be set, the code of the slave LED, and the characteristic class are displayed on the display 25 of the mounter 20(2). In the present embodiment, among the characteristic classes of the slave LEDs in each of the combination Nos. 4 to 6, the highest-ranked characteristic class No. 4, that is, "793.060 - 50"... "61" is displayed. Here, it can be assumed that the slave LEDs with higher characteristic classes are generally used more often than those with lower characteristic classes. Note that the characteristic classes of the combination Nos. with lower ranks may be displayable by scrolling or the like. Of course, the characteristic classes of the slave LEDs in all the settable combinations (Nos. 4 to 6) may be displayed.

[0026] Then, when the slave LED feeder 22 is set to the mounter 20(2) in S270, the CPU 30a acquires, as the component information of the set feeder 22, the code and characteristic class information of the slave LED accommodated in the feeder 22 through communication with the mounter 20(2) (S280). Next, the CPU 30a determines whether the slave LED is correctly set based on the acquired code and characteristic class of the slave LED (S290). In the case of the example in FIG. 9, in the process of S290, it is determined whether the acquired characteristic class matches the characteristic class of the slave LED of the topmost combination No. 4. If they do not match, it is determined whether it matches the characteristic class of the slave LED of the lower combinations No. 5 or No. 6. If the CPU 30a determines that it matches the characteristic class of any slave LED, it determines that the slave LED is correctly set. If the CPU 30a determines that the slave LED is not correctly set, it causes the mounter 20(2) to notify an error (S300) in the same manner as in S240, and returns to S260.

[0027] On the other hand, when the CPU 30a determines in S290 that the slave LED is correctly set, it selects a slave resistor corresponding to the code and characteristic class of the slave LED with reference to the management data (S310). That is, the CPU 30a selects the slave LED of the combination corresponding to the code and characteristic class of the slave LED from among a plurality of combinations defined in the management data. As shown in FIG. 10, when the feeder 22 set in the mounting machine 20(2) accommodates a slave LED with a code of "792.673-05" and a characteristic class of "793.060-62", it is determined from the management data that it is the slave LED of combination No. 5. Therefore, the slave resistor of that combination No. 5, that is, the slave resistor with a code of "733.416-50" is selected. Subsequently, the CPU 30a causes the code of the selected slave resistor to be displayed on the display 25 of the mounting machine 20, thereby instructing the setting of the feeder 22 for the slave resistor (S320), and waits for the feeder 22 to be set (S330). For example, as shown in FIG. 10, the mounting machine 20 for setting the feeder 22 for the slave resistor is the mounting machine 20(3). In S320, the slot No. of the setting destination of the feeder 22 for the slave resistor and the code of the slave resistor are displayed on the display 25 of the mounting machine 20(3).

[0028] Then, when the slave resistor feeder 22 is set in the mounter 20(3) in S330, the CPU 30a obtains the code of the slave resistor accommodated in the feeder 22 as the component information of the set feeder 22 via communication with the mounter 20(3) (S340). Next, the CPU 30a determines whether the slave resistor is correctly set based on the obtained code of the slave resistor (S350). In the case of the example in FIG. 10, in S350, it is determined whether the obtained code matches the code of the slave resistor of combination No. 5. If it is determined that they match, it is determined that the slave resistor is correctly set. When the CPU 30a determines that the slave resistor is not correctly set, similar to S240, it causes the mounter 20(3) to notify an error (S360) and returns to S320. On the other hand, when the CPU 30a determines that the slave resistor is correctly set, it ends the guidance display process.

[0029] In the light-emitting unit manufacturing process of FIG. 5, when the guidance display process of S140 (FIG. 7) ends, in each mounter 20, a master LED, a slave LED, and a slave resistor are collected from each feeder 22 and mounted on each unit substrate S2 (S150), and the light-emitting unit manufacturing process ends. As a result, since the master LED, the slave LED, and the slave resistor defined in the same combination are mounted, the light-emitting states (luminance and color) of the respective LEDs 2 within the unit substrate S2 can be made as uniform as possible.

[0030] Here, the correspondence between the components of this embodiment and the components of the present disclosure will be clarified. The LED 2 of this embodiment corresponds to the light-emitting element, the resistor 4 corresponds to the resistor element, the feeder 22 corresponds to the supply unit, the mounter 20 corresponds to the mounter, S100 in the light-emitting unit manufacturing process corresponds to step (a), and S140 in the light-emitting unit manufacturing process corresponds to step (b). The display 25 corresponds to the predetermined display unit. Further, the management device 30 that performs S100 in the light-emitting unit manufacturing process corresponds to the creation processing unit, and the management device 30 that performs S140 in the light-emitting unit manufacturing process and the mounting control device 28 correspond to the setting processing unit.

[0031] In the method for manufacturing the light-emitting unit described above, management data is created that defines a plurality of combinations of one master LED, slave LEDs selected according to the brightness and color of the master LED, and slave resistors selected according to the brightness and color of the slave LEDs. Also, based on any of the combinations defined in the management data, each feeder 22 is set in the mounter 20 to perform the mounting process. As a result, in a light-emitting unit in which a plurality of LEDs 2 and resistors 4 are combined and mounted on the same unit substrate S2, variations in the light-emitting states between the LEDs 2 can be appropriately suppressed.

[0032] Further, based on the component information of the feeder 22 set in the mounter 20 and the combination defined in the management data, the guidance display of the remaining feeders 22 to be set is updated, so that the operator can appropriately set each feeder 22 while checking the guidance display.

[0033] Also, since the guidance display is provided to set the feeders 22 of the master LED, the slave LEDs, and the slave resistors in this order, the LED 2 can be set preferentially over the resistor 4. Since the types and quantities of the LEDs 2 held in stock are often limited compared to the resistors 4, by giving priority to the LEDs 2, the feeders 22 of each component can be smoothly set even if there are restrictions due to the combination.

[0034] Also, when there are a plurality of slave LEDs with different brightness and colors as selectable slave LEDs, the top slave LED in the management data is selected and the guidance display is provided, so that the guidance display can be made easier to understand and the setting of the feeder 22 can be appropriately performed.

[0035] Note that the present invention is not limited to the above-described embodiments at all, 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.

[0036] For example, in the above-described embodiment, guidance display was performed to set the feeder 22 in the order of the master LED, the slave LED, and the slave resistor. However, the present invention is not limited to this, and guidance display may be performed in other orders such as the order of the master LED, the slave resistor, and the slave LED. Further, when any one of the feeders 22 is set, based on the component information and management data of the set feeder 22, the remaining components to be set in any combination are selected, and any guidance display may be used as long as it performs guidance display to set the feeder 22 of the component. Further, initially, guidance display of the master LED, the slave LED, and the slave resistor in any combination (for example, combination No. 1) is performed, and when any one of the feeders 22 is set, it may be updated to guidance display of another combination based on the component information and management data of the set feeder 22.

[0037] In the embodiment, guidance display was performed on the display 25 of the mounter 20. However, the present invention is not limited to this, and any predetermined display unit such as the display unit of the information terminal possessed by the operator, the display 34 of the management device 30, or the display unit within the component mounting system 10 may be used as long as it performs guidance display.

[0038] In the embodiment, guidance display for setting the feeder 22 and print output of a management data sheet for presenting management data to the operator were performed. However, in addition to this, other guidance such as voice guidance may be performed. Alternatively, the present invention is not limited to performing both guidance display and print output, and only one of them may be performed. When guidance display is not performed, the mounting machine 20 and the slot No. to which the feeder 22 should be set may be printed on the management data sheet.

[0039] In the embodiment, an example was given in which an operator sets the feeder 22. However, the present invention is not limited to this, and an automatic changer that automatically changes the feeder 22 may set the feeder 22. In that case, the CPU 30a may output a setting instruction for the feeder 22 to the automatic changer instead of the guidance display of the feeder 22. Further, the operator and the automatic changer may jointly set the feeder 22. In that case, the CPU 30a may output a setting instruction for the feeder 22 to the automatic changer and also perform a guidance display on the display 25.

[0040] In the embodiment, an example was given in which one slave LED and one slave resistor are mounted in addition to the master LED. However, the present invention is not limited to this, and a plurality of slave LEDs and slave resistors may be mounted. In that case, the slave LED may be selected according to the brightness and color of the master LED and other slave LEDs. Further, the slave resistor may be selected according to the brightness and color of at least one of the master LED and the slave LEDs.

[0041] In the embodiment, an example was given in which an LED and a resistor are mounted on the unit substrate S2 of the multi-sided chamfered substrate S1. However, the present invention is not limited to this, and an LED and a resistor may be mounted on a substrate having only one unit substrate.

[0042] Here, the manufacturing method of the light-emitting unit of the present disclosure may be as follows. For example, in the manufacturing method of the light-emitting unit of the present disclosure, in the step (b), the component supply unit to be set based on the combination determined by the management data is guided and displayed on a predetermined display unit, and when any of the component supply units is set, the component information of the component supply unit and the combination determined by the management data are used. The guidance display of the remaining component supply units to be set may be updated. By doing so, the operator can appropriately and easily set each component supply unit while checking the guidance display.

[0043] In the method for manufacturing a light-emitting unit of the present disclosure, in step (b), (b1) guiding and displaying on a predetermined display unit so as to set a component supply unit of the master LED; (b2) when the component supply unit of the master LED is set, selecting the slave LED to be set based on the information on the brightness and color of the set master LED and the combination defined in the management data, and guiding and displaying on a predetermined display unit so as to set the component supply unit of the selected slave LED; (b3) when the component supply unit of the slave LED is set, selecting the slave resistor to be set based on the information on the brightness and color of the set slave LED and the combination defined in the management data, and guiding and displaying on a predetermined display unit so as to set the component supply unit of the selected slave resistor. This way, the component supply unit can be set with the master LED and the slave LED being prioritized over the slave resistor. Since the types and numbers of LEDs prepared are often limited compared to resistors, by prioritizing the LEDs, the component supply unit can be set smoothly even with restrictions due to combinations.

[0044] In the method for manufacturing a light-emitting unit of the present disclosure, in step (b2), when there are a plurality of slave LEDs with different brightness and colors as the selectable slave LEDs, it is also possible to select the slave LED of the combination defined as the topmost in the management data among the combinations including the plurality of slave LEDs. This way, the guiding and display can be made easier to understand, and the setting of the component supply unit can be appropriately performed.

[0045] The implementation system of the present disclosure is an implementation system for mounting a plurality of LEDs together with resistors on a unit substrate by a mounting machine, As combinations of the plurality of LEDs and the resistors that can be mounted on the same unit substrate, a creation processing unit creates management data that defines a plurality of combinations of one master LED, slave LEDs selected according to the brightness and color of the master LED and other LEDs including the master LED, and slave resistors selected according to the brightness and color of the LEDs.
