The present invention relates to a component type allocating method and a component type allocating device to be allocated to a manual feeder device.

Equipment for producing boards on which a large number of components are mounted include a solder printer, a component mounter, a reflow machine, and a board inspection machine. It has become common to connect these facilities to form a substrate production line. Among them, the component mounter includes a board transfer device, a component supply device, a component transfer device, and a control device. As a typical example of the component supply device, there is a feeder device that feeds out a component storage tape that stores components in a plurality of component storage portions. In combination with this feeder device, a reel holding device that holds the component supply reel wound with the component storage tape in a rotatable and replaceable manner is used.

Then, the plurality of component types of the components to be mounted on the board are arranged at a plurality of arrangement positions arranged in a row. At this time, the production efficiency of the board changes depending on the arrangement order of the plurality of component types. Therefore, a technique for simulating the component type arrangement has been developed in consideration of the moving distance of the mounting head of the component transfer device, and an example is disclosed in Patent Document 1. In the device placement determination method of Patent Document 1, the management device determines the placement of the plurality of feeder devices so that the mounting cycle time (tact time) required to produce one board is shortened. At this time, the difference in the types of the plurality of feeder devices, the conditions of the types of components that can be supplied, and the like are considered (see paragraphs 0026 and 0027 of Patent Document 1).

JP, 2009-130337, A

By the way, when the components stored in the component storage tape in the conventional manual feeder device are exhausted during the production of the board, a splicing operation for supplementing and connecting a new component storage tape is required. The splicing work is troublesome for workers because it takes a lot of time and is one of the causes for reducing the production efficiency. As a countermeasure against this, an automatic feeder device (so-called auto-loading feeder) has been developed which has an automatic loading function for automatically loading a component storage tape and greatly reduces the splicing work.

In contrast to the recent development trend of the feeder device, the technique of Patent Document 1 does not consider the difference in workability between the automatic feeder device and the manual feeder device. That is, according to the technique of Patent Document 1, splicing work cannot be reduced even if the direct mounting cycle time for executing the board production can be shortened, and the overall production efficiency including the splicing work time can be improved. difficult. From another perspective, establish a method for allocating component types to automatic feeder devices and manual feeder devices so that the automatic feeder device, which has good workability and is highly convenient when refilling component storage tapes, can be effectively used. It is necessary.

The present invention has been made in view of the above-mentioned problems of the background art, reduces the splicing work by effectively utilizing the automatic feeder device, and a component type allocation method that can contribute to the improvement of the production efficiency of the board, It is an issue to be solved to provide a component type allocation device.

The component type allocating method of the present invention which solves the above-mentioned problems is an automatic feeder device having an automatic loading function for automatically loading a component storage tape when a component storage tape storing a component is inserted into each of a plurality of component storage portions. And a method of allocating a plurality of component types to a manual feeder device that does not have an automatic loading function, wherein a new component is stored when the component storage tape loaded in the manual feeder device runs out of components. Workability evaluation step of evaluating the amount of labor of splicing work for replenishing and connecting the storage tape for each component type of the component, and preferentially assigning the component type having the large labor of the splicing work to the automatic feeder device. It has an automatic allocation step.

In the component type allocating method of the present invention, the amount of time and effort required for the splicing work in the manual feeder device is evaluated, and the component type having the great labor for the splicing work is preferentially assigned to the automatic feeder device. Therefore, the automatic feeder device is preferentially used over the manual feeder device, and the automatic feeder device can be effectively used to reduce the splicing work. Further, since the labor of the splicing work in the manual feeder device is reduced from the large order, it is possible to contribute to the improvement of the substrate production efficiency.

(1. Overall configuration of component mounter 1)
First, the overall configuration of the component mounter 1 that performs the component type allocation method according to the embodiment of the present invention will be described with reference to FIG. FIG. 1 is a plan view schematically showing the overall configuration of the component mounter 1 in a simplified form. The direction from the right side to the left side of the paper in FIG. 1 is the X-axis direction in which the substrate K is loaded and unloaded, and the direction from the rear below the paper to the front above the paper is the Y-axis direction.

The substrate transfer device 12 includes a pair of first and second guide rails 121 and 122, a pair of conveyor belts, and a clamp device. The first and second guide rails 121 and 122 extend in the transport direction (X-axis direction) across the center of the upper surface of the machine base 19 and are attached to the machine base 19 in parallel with each other. Inside the first and second guide rails 121 and 122 facing each other, a pair of endless annular conveyor belts (not shown) is arranged in parallel. The pair of conveyor belts rotates with both edges of the substrate K placed on the conveyor transport surface, and carries the substrate K into and out of the mounting execution position set in the center of the machine base 19. A clamp device (not shown) is provided below the conveyor belt at the mounting position. The clamp device pushes up the substrate K and clamps it in a horizontal posture to position it at the mounting execution position. As a result, the component transfer device 14 can perform the mounting operation at the mounting execution position.

The manual feeder device 7 and the automatic feeder device 9 sequentially supply the parts. Each of the feeder devices 7 and 9 has a flat shape with a small widthwise dimension, and is arranged in rows in the first to ninth slots SL1 to SL9 of the common pallet 5 mounted on the machine base 19 (details will be described later). In FIG. 1, the automatic feeder device 9 is arranged in the fourth and fifth slots SL4 and SL5, and the manual feeder device 7 is arranged in the other slots SL1 to SL3 and SL6 to SL9.

The pair of Y-axis rails 141 and 142 are arranged near both side surfaces of the machine base 19 and extend in the front-rear direction (Y-axis direction). A Y-axis slider 143 is mounted on the Y-axis rails 141 and 142 so as to be movable in the Y-axis direction. The Y-axis slider 143 is driven in the Y-axis direction by a Y-axis ball screw mechanism (not shown).

The mounting head 144 is mounted on the Y-axis slider 143 so as to be movable in the X-axis direction. The mounting head 144 is driven in the X-axis direction by an X-axis ball screw mechanism (not shown). The nozzle tool 145 is replaceably held by the mounting head 144. The nozzle tool 145 has one or a plurality of suction nozzles that suck components and mount them on the substrate K. The board camera 146 is provided on the mounting head 144 side by side with the nozzle tool 145. The board camera 146 images the fiducial mark attached to the board K to detect the accurate position of the board K.

The component camera 15 is provided upward at the center position in the width direction of the upper surface of the machine base 19 between the substrate transfer device 12 and the feeder devices 7 and 9. The component camera 15 images the state of the component sucked by the suction nozzle while the mounting head 144 is moving from the feeder devices 7 and 9 onto the substrate K. If an error in the suction posture of the component, a shift in the rotation angle, or the like is found from the image data of the component camera 15, the control device 16 finely adjusts the component mounting operation as necessary, and if the component is difficult to mount, the component concerned Control to discard.

In addition, the control device 16 sequentially collects and updates operation status data such as the number of production of the completed boards K, the mounting time required for mounting the components, and the number of occurrences of component suction errors.

(2. Configuration example of automatic feeder device 9, reel holding device 6, and manual feeder device 7)
Next, a configuration example of the automatic feeder device 9 and the reel holding device 6 will be described. FIG. 2 is a side view showing a configuration example of a state in which the automatic feeder device 9 and the reel holding device 6 are mounted on the common pallet 5.

The common pallet 5 is detachably mounted on the upper side of the machine base 19. The invention is not limited to this, and the common pallet 5 may be fixedly installed on the upper side of the machine base 19. The common pallet 5 has a feeder mounting portion 51 and a reel mounting portion 55. The feeder mounting portion 51 is formed by providing an upright portion 53 on the front side of a substantially rectangular flat surface portion 52, and has a substantially L shape in a side view. Nine first to ninth slots SL1 to SL9 extending in the front-rear direction are engraved on the plane portion 52 side by side in the width direction. FIG. 1 shows the width-direction positions of the first, fifth, and ninth slots SL1, SL5, SL9. The automatic feeder device 9 is inserted and mounted from the rear of the slots SL1 to SL9 toward the front upright portion 53. The first to ninth slots SL1 to SL9 correspond to the positions where the feeder devices 7 and 9 are arranged.

The automatic feeder device 9 has a tape insertion port 91 near the intermediate height at the rear end and an insertion lever 92 near the upper part of the rear end. By lifting the insertion lever 92, the first and second component storage tapes 85 and 86 can be sequentially inserted into the tape insertion opening 91. A feeding rail 93 is provided from the tape insertion opening 91 of the automatic feeder device 9 toward the upper front end. A supply position 94 is set on the upper surface near the front end of the feeding rail 93. A standby position 96 is set on the upper surface of the feeding rail 93 near the rear of the tape insertion opening 91. The inserted first and second component storage tapes 85 and 86 advance to the standby position 96 and temporarily stop.

A tape controller 95 is provided above the standby position 96. The tape controller 95 allows the first component storage tape 85 to be fed out from the standby position 96, and causes the second component storage tape 86 to stand by. Moreover, when the first component storage tape 85 is used up, the tape control unit 95 automatically allows the second component storage tape 86 to be fed out from the standby position 96. Therefore, the splicing work for connecting the first and second component storage tapes 85 and 86 is unnecessary. The specific configuration of the tape control unit 95 is disclosed in, for example, JP-A-2014-82445.

Further, the automatic feeder device 9 includes a tape feeding mechanism (not shown) including a servo motor and a sprocket. When the first component storage tape 85 is inserted to the standby position 96, the automatic feeder device 9 drives the servo motor in the normal direction. As a result, the automatic feeder device 9 automatically feeds and loads the first component storage tape 85, and the substrate K is ready for production. That is, the automatic feeder device 9 has an automatic loading function. The second component storage tape 86 may be inserted immediately after the first component storage tape 85 has been inserted, or during the production using the first component storage tape 85.

Further, when the automatic feeder device 9 receives the discharge command, it drives the servo motor in the reverse direction. As a result, the automatic feeder device 9 discharges the cut front end of the loaded first or second component storage tape 85, 86 from the supply position 94 toward the tape insertion port 91. That is, the automatic feeder device 9 has an automatic discharging function. The discharge command is issued from the control device 16 or an unillustrated discharge button attached to the automatic feeder device 9 is pressed by the operator. The automatic feeder device 9 includes the tape control unit 95 and has an automatic loading function, so that the time and effort for replenishing a new component storage tape is greatly reduced. The applicant of the present application has already applied for a detailed configuration example of the automatic feeder device 9 in International Application JP2014/064443, International Application JP2014/083619, and the like.

The reel mounting portion 55 of the common pallet 5 is composed of two arm members 56, a front transfer plate 57, a rear transfer plate 58, and the like. The reel mounting portion 55 can mount one or a plurality of reel holding devices 6. As described in detail below, the two arm members 56 are fixed to the rear portions on both sides of the feeder mounting portion 51 in the width direction. The arm member 56 is formed so as to extend horizontally rearward at the beginning, then extend so as to incline rearward and downward, and end extend horizontally rearward. A front transfer plate 57 is provided so as to connect the inclined portions of the two arm members 56. A rear transfer plate 58 is provided so as to connect the rear horizontal portions of the two arm members 56. The reel holding device 6 is detachably mounted on the upper side of the front transfer plate 57 and the rear transfer plate 58.

The reel holding device 6 holds the first and second component supply reels 81 and 82 side by side in the front-rear direction so as to be rotatable. The reel holding device 6 is not limited in size in the width direction (direction of the reel axis), and holds one or a plurality of first and second component supply reels 81, 82 side by side in the width direction. Therefore, the reel holding device 6 is mounted behind the one or more automatic feeder devices 9.

When there are no more components stored in the second component storage tape 86 loaded in the automatic feeder device 9, the worker replaces the reel holding device 6 arranged behind the automatic feeder device 9 or Only the first and second component supply reels 81, 82 are replaced. Subsequently, the worker pulls out the first and second component storage tapes 85 and 86 from the first and second component supply reels 81 and 82 and inserts them from the tape insertion opening 91 of the automatic feeder device 9 to the standby position 96. This insertion work is lighter than the splicing work for connecting the two component storage tapes 85 and 86. As a result, the automatic loading function of the automatic feeder device 9 operates, and the first and second component storage tapes 85 and 86 are sequentially fed to the supply position 94.

On the other hand, the manual feeder device 7 is integrally provided with a reel holding device and directly holds the component supply reel. When there are no more components stored in the component storage tape loaded in the manual feeder device 7, the worker needs to replenish the new component supply reel and perform the splicing work to connect the two component storage tapes. is there. The splicing work is a troublesome work for the operator. Since the manual feeder device 7 can be configured based on various known techniques, detailed description will be omitted.

(3. Parts type allocation method of the embodiment)
Next, the component type allocation method of the embodiment will be described with reference to FIGS. 3 and 4. The component type allocating method of the embodiment is realized by an arithmetic processing function of a controller (host computer) (not shown) that manages a board production line including the component mounter 1. The component type allocation method is not limited to this, and may be realized by the control device 16 of the component mounter 1 or a separate computer device that shares various data such as mounting sequence data. FIG. 3 is a diagram showing a calculation processing flow of the component type allocation method of the embodiment. Further, FIG. 4 is a diagram illustrating an example of the contents of the arithmetic processing of the arithmetic processing flow.

As a precondition, assume a simple example in which four types of components PA, PB, PC, and PD are mounted on a board K to be produced. Of these, the three types of parts PA, PB, and PC can be supplied from either the automatic feeder device 9 or the manual feeder device 7. The components of the component type PD correspond to the excluded component types described later and can be supplied only from the manual feeder device 7. It is also assumed that two automatic feeder devices 9 are prepared and a manual feeder device 7 is also prepared. In many cases, more types of components are actually mounted on the board K, and the number of automatic feeder devices 9 is three or more in many cases.

In step S1 of FIG. 3, the control device sets the allocation mode based on the input setting operation of the operator. As the allocation mode, either the workability evaluation mode M1 or the mounting point priority mode M2 is alternatively set. The workability evaluation mode M1 is a mode in which component types are assigned based on the amount of time and effort required for splicing work. On the other hand, the mounting point priority mode M2 is a mode in which the component type is allocated based on the mounting point number N of the components mounted on one board K.

In step S2, the control device confirms the presence or absence of the excluded component type. The excluded component type is a component type that cannot be supplied from the automatic feeder device 9 due to a reason such as a special shape, or is preferably supplied from the manual feeder device 7. The control device excludes the component type D, which is the excluded component type, from the target of the arithmetic processing during workability evaluation steps S4 to S6 and steps S14 to S16 described below.

In step S3, the control device controls the branch of the arithmetic processing flow based on the set mode. That is, the control device advances the execution of the arithmetic processing flow to the workability evaluation step S4 if the workability evaluation mode M1 is set, and executes the arithmetic processing flow if the mounting point priority mode M2 is set to step S14. Proceed to.

In the workability evaluation step S4, the control device evaluates the amount of time and effort required for the splicing work. More specifically, the control device determines the amount of time and effort required for splicing work to replenish and connect a new component storage tape when the components stored in the component storage tape loaded in the manual feeder device 7 run out. Evaluate for each component type. In the present embodiment, the execution frequency S of the splicing work is used as an index indicating the amount of time and effort required for the splicing work. This is because if the execution frequency S is high, the number of splicing operations is increased, which is troublesome.

The control device creates workability evaluation data in order to evaluate the execution frequency S of the splicing work. As shown in FIG. 4, workability evaluation data is created based on the mounting sequence data and the component data. The mounting sequence data is data in which the types of components to be mounted on the board K, the mounting positions, the mounting order, and the like are summarized. The mounting sequence data indicates the number N of mounting points of each component type PA, PB, and PC mounted on one board K. The number of mounting points NA of the component type PA=100, the number of mounting points NB of the component type PB=50, and the number of mounting points NC of the component type PC=100.

On the other hand, the component data is data in which information about each component used in the component mounter 1 is collected. The component data includes reel names of the respective component types PA, PB, PC, the number of storage points Q that means the total number of components stored in the component storage tape, shape information of the components, and the like. The number of storage points QA of the component type PA=10,000, the number of storage points QB of the component type PB=3000, and the number of storage points of the component type PC QC=20,000.

The control device divides the mounting point number N by the storage point number Q for each of the component types PA, PB, and PC to calculate the execution frequency S of the splicing work. The unit of the execution frequency S is (times/sheet). The execution frequency SA for the component type PA is calculated as SA=(NA/QA)=(100/10000)=(1/100). This means that the splicing work for the component type PA is performed once every 100 substrates are produced. Similarly, the execution frequency SB related to the part type PB is calculated as SB=(50/3000)=(1/60), and the execution frequency SC related to the part type PC is calculated as==(100/20000)=(1/200). It

Further, the control device ranks the priorities Y in descending order of the execution frequency S. That is, the priority YB of the component type PB having the highest execution frequency SB is set to 1st place, and the priority YA of the component type PA having the intermediate execution frequency SA is set to 2nd place, and the part having the lowest execution frequency SC. The priority YC of the product type PC is set to the third place. As a result, the workability evaluation data shown in FIG. 4 is completed.

In the next step S5, the control device preferentially allocates to the automatic feeder device 9 in order from the component type having the highest priority Y. In the first step S5, the control device allocates the component type PB having the priority YB=1st to the first automatic feeder device 9. In the next step S6, the control device returns the execution of the arithmetic processing flow to step S5 if there is a remaining number of the automatic feeder device 9 to which the component type is not assigned, and executes the arithmetic processing flow if there is no remaining number. Proceed to step S7. In the first step S6, since the component type is not assigned to the second automatic feeder device 9, the control device returns the execution of the arithmetic processing flow to step S5.

In step S5 for the second time, the control device allocates the component type PA having the second priority YA=second to the second automatic feeder device 9. In step S6 of the second time, the remaining number of automatic feeder devices 9 is exhausted, so the control device advances the execution of the arithmetic processing flow to step S7. The loop calculation process including steps S5 and S6 corresponds to the automatic allocation step of the present invention.

In step S7 after exiting from the loop calculation process, the control device allocates to the manual feeder device 7 the component type PC having the third highest priority YC=not assigned yet and the component type D that is an excluded component type.

In step S14, which is performed when the mounting point number priority mode M2 is set in step S3, the control device ranks the priorities Z in descending order of the mounting point number N. In other words, the number of mounting points NA=the number of mounting points NC=100 is large, and the priority ZA of the component type PA is equal to the first rank and the priority ZC of the component type PC is equal to the first rank. Further, the number of mounting points NB is as small as 50, and the priority ZB of the component type PB is 3rd.

In the next step S15 and step S16, similarly to the workability evaluation mode M1, the control device preferentially allocates to the automatic feeder device 9 in order from the component type having the highest priority Z. Specifically, the control device allocates the component type PA and the component type PC having the priority ZA=the priority ZC=the first place with the same ratio to the two automatic feeder devices 9. As a result, the remaining number of automatic feeder devices 9 is exhausted, and the control device advances the execution of the arithmetic processing flow to step S7. In step S7, the control device allocates to the manual feeder device 7 the part type PB with the priority ZB=3rd that is not yet allocated and the part type D that is an excluded part type.

As described above, depending on the setting of the allocation mode, different allocation results may occur. If the mounting point priority mode M2 is set, the component type PB having the highest execution frequency SB of the splicing work is allocated to the manual feeder device 7. As a result, the number of splicing operations is increased and the production stop time due to the operations is increased. On the other hand, when the workability evaluation mode M1 is set, the component type PC having the smallest execution frequency SC of the splicing work is allocated to the manual feeder device 7, and the number of splicing works is reduced. Therefore, the workability evaluation mode M1 is usually superior to the mounting point priority mode M2.

In subsequent step S8, the control device performs allocation adjustment processing. In the allocation adjustment process, the mounting sequence of each component type A to D, the arrangement order of arranging the manual feeder device 7 and the automatic feeder device 9 in the first to ninth slots SL1 to SL9, etc. are adjusted, and the mounting sequence data is updated. To be done. As a general tendency, the automatic feeder device 9, which is advantageous in reducing the splicing work, is often applied to a component type that is quickly consumed. Therefore, the automatic feeder device 9 is often arranged near the center in the width direction close to the component camera 15 and the substrate K, but it is not unconditionally determined. Since various techniques have been publicly known for the allocation adjustment process, detailed description thereof is omitted.

(4. Aspects and effects of the embodiment)
The component type allocating method according to the embodiment is an automatic feeder having an automatic loading function for automatically loading the component storage tapes 85 and 86 when the component storage tapes 85 and 86 respectively storing the components are inserted into the plurality of component storage portions. A method of allocating a plurality of component types PA to PD to the device 9 and the manual feeder device 7 having no automatic loading function, which is a component type allocating method in which the components stored in the component storage tape loaded in the manual feeder device 7 are When it runs out, a workability evaluation step S4 is performed to evaluate the amount of time and effort required for replenishing and connecting a new component storage tape for each of the component types PA, PB, and PC of the component, and the component type requiring a large amount of splicing work. There is an automatic allocation step (steps S5 and S6) for preferentially allocating PB and PA to the automatic feeder device 9.

According to this, the amount of time and effort required for the splicing work in the manual feeder device 9 is evaluated, and the types of parts that require the long time and effort for the splicing work are preferentially allocated to the automatic feeder device 9. Therefore, the automatic feeder device 9 is preferentially used with respect to the manual feeder device 7, and the automatic feeder device 9 can be effectively used to reduce the splicing work. Further, since the labor of the splicing work in the manual feeder device 7 is reduced from the largest order, the production efficiency of the substrate K can be improved.

Further, in the workability evaluation step S4, at least one item of the frequency S of performing the splicing work in the manual feeder device 7, the difficulty of the splicing work depending on the difference in the properties of the component storage tapes 85 and 86, and the time required for the splicing work Based on the above, it is possible to evaluate the size of the splicing work.

In addition to the execution frequency S, the degree of difficulty and the required time can be adopted as an index indicating the amount of time and effort required for the splicing work. For example, the difficulty level of the splicing work depends on the difference in the material and hardness of the component storage tapes 85 and 86. Further, the difference between the embossed tape in which the component storage portion is formed in a convex shape and the flat tape having a flat surface also affects. Therefore, the work reducing effect becomes remarkable by preferentially allocating the component type having a high difficulty level of the splicing work to the automatic feeder device 9.

Furthermore, two or more indexes that represent the size of the splicing work can be combined. For example, when the time required for the splicing work changes depending on the property of the component storage tape, it is preferable to use the product of the execution frequency S and the time required. The production stop time can be shortened by preferentially allocating the component type having a large product to the automatic feeder device 9.

Further, in the workability evaluation step S4, the number N of mounting points of each component mounted on one board K is divided by the number Q of storing each component stored in the component storage tapes 85 and 86 to perform the splicing work. The execution frequency S is calculated respectively, and it is evaluated that the greater the execution frequency S is, the more troublesome the splicing work is. According to this, the execution frequency S can be easily calculated using the mounting sequence data and the component data created in advance for the production of the board K, and the labor of the splicing work can be easily evaluated.

The component type allocating method of the embodiment may be implemented as a component type allocating device. The component type allocating device may be realized by an arithmetic processing function of a controller (host computer) (not shown) that manages a board production line including the component mounter 1, and is not limited to this. It may be realized by the control device 16 of the mounting machine 1 or a separate computer device that shares various data such as mounting sequence data. That is, the component allocation device according to the embodiment has an automatic loading function that automatically loads the component storage tapes 85 and 86 when the component storage tapes 85 and 86 storing the components are inserted into the plurality of component storage portions. A component type allocating device for allocating a plurality of component types PA to PD to the feeder device 9 and the manual feeder device 7 having no automatic loading function, the components being stored in the component storage tape loaded in the manual feeder device 7. When the problem disappears, a workability evaluation unit that evaluates the amount of time and effort required to replenish and connect a new component storage tape for each component type PA, PB, and PC, and the type of component that requires a large amount of splicing work Can be configured to have an automatic allocation unit that preferentially allocates to the automatic feeder device 9.

The operation and effect of the component type allocation device of this embodiment are the same as those of the component type allocation method of this embodiment.

(5. Application and modification of the embodiment)
When the number of automatic feeder devices 9 is larger than the number of component types and there is no excluded component type, the manual feeder device 7 is not necessary. In addition, the exemplary description of the embodiment is a simplified one, and in reality, a larger number of component types are often allocated to a larger number of automatic feeder devices 9 and manual feeder devices 7. Further, the mounting point priority mode M2 may not be used, and steps S1, S3, and S14 to S16 of the arithmetic processing flow shown in FIG. 3 may be omitted.
