For example, as a dropping device for dropping a liquid such as a liquid crystal, the one described in JP-A-2006-55853 (Patent Document 1 below) is known. This dropping device includes a dispenser for holding a liquid and a control device for adjusting the temperature and dropping amount of the liquid in the dispenser.

Japanese Unexamined Patent Publication No. 2006-55853

By the way, in general, a liquid used for dropping or coating is in a state such as viscosity or volume depending on, for example, room temperature, pressure applied to a dispenser due to the remaining amount of liquid, and elapsed time after opening the liquid (period after opening). Changes. Therefore, even when the temperature of the liquid is controlled, the dropping amount and the coating area may vary due to factors other than the temperature of the liquid, or the liquid may be stringed. Therefore, in order to adjust the output amount of the liquid, it is necessary to actually perform the adjustment work multiple times such as inspecting the output amount of the liquid, which increases the output amount of the liquid and the work time of the adjustment work. The manufacturing cost will increase.

This specification discloses a technique for reducing the output amount of the liquid and the working time of the adjustment work.

The coating device disclosed by the present specification is a coating device that applies a coating agent to an object, and is a dispenser that adjusts the temperature of the coating agent and applies the coating agent to the object, and the dispenser. A device for inspecting the coating amount of the coating agent, a plurality of factor data in which the factor values of a plurality of factors affecting the coating amount of the coating agent are set as a set, and each factor data of the plurality of factor data. A storage unit and a control unit for storing a plurality of coating information indicating control conditions for controlling the coating amount of the coating agent corresponding to the above are provided, and the control unit is used when applying the coating agent. Condition determination for determining the control condition of the coating agent based on the comparison result between the coating condition in which the factor values of a plurality of factors are set as a set and the factor data of the plurality of coating information in the storage unit. The treatment is executed, and the coating amount of the dispenser to be applied based on the control conditions determined in the condition determination process is inspected by the inspection device.

Further, the technique disclosed in the present specification is a surface mounter, which includes a coating device, a transport device for transporting the object, a dispenser, and a mounting head for mounting an electronic component on the object. It is equipped with a component mounting device and the like.

According to such a coating device, the coating conditions are compared with the factor data in a plurality of coating information, factor data similar to the coating conditions is selected, and appropriate control conditions are set based on the plurality of coating information. Can be decided. That is, a coating agent close to an appropriate coating amount can be applied to the object. As a result, the working time of the adjustment work for applying the coating material and adjusting the coating amount and the coating amount of the coating agent can be reduced, and further, the increase in the manufacturing cost can be suppressed.

The coating apparatus disclosed by the present specification may have the following configuration.
A priority is set for each of the factors, and in the condition determination process, the control unit determines the factor data in the coating condition and the plurality of coating information based on the priority in the factor. It may be configured to compare with.
According to such a configuration, an appropriate control condition can be determined by comparing the coating condition and the factor data in the coating information based on the priority of each factor.

That is, since the control conditions can be determined based on the priority of the factors with large fluctuations in the coating amount, for example, factor data similar to the coating conditions is selected as compared with the case where the priority is not set for each factor. Therefore, more appropriate control conditions can be determined.

In the condition determination process, the control unit may have a configuration in which the factor data in the plurality of coating information and the coating condition are compared in descending order of priority of the factors.
According to such a configuration, among a plurality of factors, it is possible to compare the factor data in the coating information with the coating conditions in descending order of priority by increasing the priority of the factor having a large fluctuation in the coating amount. As a result, for example, as compared with the case where the control conditions of all the factors are compared and the control conditions are arranged and determined based on the priority, the factor data similar to the application conditions can be selected in a short time and the appropriate control conditions are selected. Can be determined.

In the condition determination process, the control unit selects the coating information whose factor value of the factor data is close to the factor value of the coating condition from the plurality of coating information, and the selected coating information. The control condition may be determined as the control condition of the coating agent.

According to such a configuration, the control condition of the coating agent can be determined by a simple method of selecting the coating information having a factor value close to the factor value of the coating condition. Therefore, for example, the coating information is selected by a complicated process. Compared with the case, the control conditions of the coating agent can be easily determined.

An allowable range is set for each of the factors, and the control unit includes the factor value in the factor data among the plurality of coating information in the allowable range of the factor value in the coating condition. The narrowing down process for selecting the coating information to be applied may be executed, and the condition determination process may be executed after the narrowing down process is executed.

According to such a configuration, the number of coating information to be compared with the coating conditions can be reduced by setting an allowable range for each factor value and selecting coating information similar to the coating conditions. it can. As a result, the processing time in the condition determination process can be shortened, so that the working time of the adjustment work and the application amount of the coating agent can be further reduced.

The factor of one of the plurality of factors is the period after opening of the coating agent, and the coating agent has an expiration date and a priority switching deadline set before a predetermined time of the expiration date. The control unit changes the priority of the coating agent to the highest priority in the post-opening period of the coating agent when the post-opening period of the coating agent has passed the priority switching deadline. However, the condition determination process or the narrowing-down process may be executed after the change.

For example, when the room temperature is high and the coating agent is easily deteriorated, or when a coating agent which is easily deteriorated is used, the period after opening the coating agent (elapsed time after opening) becomes a factor of large fluctuation in the coating amount. Therefore, when the period after opening is before the predetermined time of the expiration date of the coating agent, that is, when the period after opening is close to the expiration date of the coating agent, the priority of the period after opening the coating agent is set to the highest. Appropriate control conditions can be determined according to the altered coating agent.

The storage unit stores a plurality of priority management tables indicating the priority of each of the factors, and the control unit changes the priority management table to change the priority of the coating agent for the period after opening. The priority may be changed.

According to such a configuration, for example, a priority management table showing the priority of factors in normal times, a priority management table showing the priority of factors when the expiration date is approaching, and the like are stored in the storage unit. .. Then, the priority management table is changed depending on whether or not the priority switching deadline has passed after the opening of the coating agent. That is, the priority can be changed according to the condition of the coating agent before and after the deterioration of the coating agent, and an appropriate control condition can be determined according to the condition of the coating agent.

The control unit may be configured to notify when the period after opening the coating agent has passed the expiration date.
According to such a configuration, before executing the comparison process or the narrowing-down process, the operator can promptly confirm whether or not the coating agent can be used by notifying that the coating agent has passed the expiration date. As a result, for example, it is possible to avoid applying an excessively altered coating agent, and it is possible to reduce the working time of the adjustment work and the coating amount of the coating agent.

According to the present disclosure, the working time of the adjustment work and the amount of the coating agent applied can be reduced.

After the applied coating agent is imaged by the substrate imaging camera 19B, the roll paper 22 is wound by a winding device to expose a new portion of the roll paper 22 from the exposure window 23. That is, by winding the roll paper 22, the coating agent can be applied to the roll paper 22 a plurality of times.

Next, the electrical configuration of the surface mounter 10 will be described with reference to FIG.
The entire surface mounter 10 is controlled and controlled by the control unit 110. The control unit 110 includes an arithmetic processing unit 111, a storage unit 112, a drive control unit 113, an image processing unit 114, a component supply control unit 115, an external input / output terminal 116, and the like, which are composed of a CPU and the like.

The storage unit 112 is composed of a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The storage unit 112 stores various programs and various data executed by the arithmetic processing unit 111. Specifically, various programs include a mounting program that controls the component mounting device 13, the transport device 12, and the component supply device 14 to arrange the electronic component EL on the printed circuit board P, and a coating amount that determines the coating amount of the coating agent. A determination program, a coating program for applying a coating agent to the printed circuit board P, and the like are stored.

As various data, a plurality of factors F for each coating agent, a priority switching deadline DL2, a plurality of factors F affecting the coating amount of the coating agent, and a plurality of factor values FV of those factors F are set as a set. Factor data FD, multiple coating information I indicating the control conditions (for example, syringe pressurization pressure, coating time, etc.) CC corresponding to the factor data FD for controlling the coating amount of the coating agent to an appropriate coating amount, each of them. A plurality of priority management tables T and the like indicating the priority PR of the factor F and the allowable range R are stored.

Expiration date of coating agent DL1 is an expiration date that needs to be confirmed in order to use the coating agent. The priority switching deadline DL2 is a deadline set before a predetermined period from the expiration date DL1 of the coating agent. Specifically, the priority switching deadline DL2 of the coating agent having an expiration date of 6 months is 5 months one month before the expiration date DL1. As shown in FIGS. 6 and 7, the expiration date DL1 and the priority switching deadline DL2 of the coating agent are managed by the table switching determination table JT together with the priority management table T used within the respective deadlines.

In the table switching determination table JT of the present embodiment, it is shown that the priority management table 1 is used within the priority switching deadline DL2, and the priority management table 2 is used after the priority switching deadline DL2 and within the expiration date DL1. Has been shown to be used.

Examples of the plurality of factors F that change the coating amount of the coating agent include room temperature, the remaining amount of the coating agent in the syringe 19A, the period after opening the coating agent (elapsed period after opening), and the like. These factors F are considered to be factors F that are more difficult to control than the control condition CC. The factor data FD is a set of the factor values FV of the factors F that are difficult to control.

As shown in FIG. 10, the coating information I is stored in the storage unit 112 as a set of the factor data FD and the control condition CC for controlling the coating agent to an appropriate coating amount.

In the present embodiment, as shown in FIG. 10, the factor F of the syringe data 1 in the application information I of the case A is the room temperature, the remaining amount of the syringe, and the period after opening (elapsed period after opening). The factor value FV of each factor F has a room temperature of 20 ° C., a remaining amount of syringe of 20 cc, and a period of one month after opening, and a set of these is regarded as factor data FD. The control conditions CC for appropriately controlling the coating amount of the coating agent in this factor data FD are AAA for the syringe, NNN for the nozzle, 0.30 for the syringe pressurizing pressure, 38 ° C. for the temperature, and 2 for the temperature error. It is said that.

Further, the factor data FD of the syringe data 2 in the coating information I of the case A has a temperature of 20 ° C., a remaining amount of the syringe of 10 cc, and a period after opening for 3 months. The control conditions CC for proper control are AAA for the syringe, NNN for the nozzle, 0.20 for the syringe pressurizing pressure, 32 ° C. for the temperature, and 1 for the temperature error.

In the priority management table T, a priority PR and an allowable range R of a factor F that is difficult to control are set. The priority PR of each factor F is set so that the amount of the coating agent applied greatly fluctuates due to the change of the factor value FV of the factor F.
In the present embodiment, as shown in FIG. 7, two priority management tables T of the priority management table 1 and the priority management table 2 are stored in the storage unit 112. As the priority management table T, the priority management table 1 is usually used. For the coating agent that easily deteriorates, the two priority management tables T are switched and used based on the table switching determination table JT.

In the priority management table 1, as shown in FIG. 7, the one with the highest priority PR is set as priority 1, and the one with the highest priority is set in the order of room temperature, remaining amount of syringe, and period after opening. The permissible range R of room temperature in the priority management table 1 is ± 3 ° C., the permissible range R of the remaining amount of syringe is ± 2 cc, and the permissible range R of the period after opening is ± 2 months.

On the other hand, the priority management table 2 is set in the order of the post-opening period, the room temperature, and the remaining amount of the syringe so that the post-opening period has the highest priority (priority 1). The permissible range R of room temperature in the priority management table 2 is ± 3 ° C., the permissible range R of the remaining amount of syringe is ± 2 cc, and the permissible range R of the period after opening is ± 1 month.

The drive control unit 113 drives the transfer device 12, the drive device 17, the inspection device 20, and the like according to the command of the arithmetic processing unit 111.
The image processing unit 114 captures the imaged data captured by the substrate imaging camera 19B according to the command of the arithmetic processing unit 111, and the image processing unit 114 captures the image data IM based on the captured image signal (see FIG. 4). To generate.

The component supply control unit 115 controls the component supply device 14 according to a command from the arithmetic processing unit 111.
The external input / output terminal 116 includes an input device such as a touch panel, a keyboard, and a mouse, and an output device such as a display. For example, the operator confirms various information displayed on the output device, operates the input device, and gives an instruction to the control unit 110. In the present embodiment, the coating condition DC and the like when the operator applies the coating agent to the printed circuit board P are input from the external input / output terminal 116.

Here, the coating condition DC input by the operator is a factor F that is difficult for the operator to control. In the present embodiment, the factors F of the coating condition DC are the room temperature, the remaining amount of the syringe, and the period after opening.

The arithmetic processing unit 111 controls each unit of the surface mounter 10 by executing various control programs of the storage unit 112. The arithmetic processing unit 111 drives and controls the transfer device 12 and the component mounting device 13 via the drive control unit 113, for example, based on the mounting program of the storage unit 112. Further, the component supply device 14 is controlled via the component supply control unit 115.

Further, the arithmetic processing unit 111 determines the control condition CC of the coating amount of the coating agent to be applied by the dispenser 19 according to the coating amount determination program stored in the storage unit 112. Then, the coating agent is applied to the inspection device 20 a plurality of times to determine the optimum coating amount of the coating agent. Then, the arithmetic processing unit 111 applies the coating agent of the coating amount determined by the coating amount determining program to the printed circuit board P by the coating agent coating program stored in the storage unit 112.

The coating amount determination process for determining the coating amount of the coating agent by the coating amount determining program will be described below.
Generally, a coating agent such as cream solder or an adhesive for mounting the electronic component EL on the printed circuit board P is hemispherically output from the output port of the dispenser 19. The coating agent is applied to the printed circuit board P in dots by the dispenser 19 descending toward the printed circuit board P in a state where the coating agent is output.

However, the viscosity and volume of the coating agent change depending on the room temperature, the pressure applied to the dispenser 19 due to the remaining amount of the coating agent, and the period after opening the coating agent.
Therefore, even when controlling the temperature of the coating agent, the coating amount of the coating agent may vary depending on factors other than the temperature of the coating agent (room temperature, remaining amount of the coating agent, period after opening, etc.), or the coating agent may be threaded. Pulling etc. may occur. Therefore, in order to adjust the coating amount of the coating agent, the adjustment work such as actually applying the coating agent and inspecting the coating amount is performed a plurality of times. Then, the working time of the adjustment work and the coating amount of the coating agent increase, and the manufacturing cost increases.

Therefore, in the present embodiment, the control unit 110 executes the coating amount determination process in the coating amount determination program by the arithmetic processing unit 111, and determines the control condition CC for adjusting the coating amount to an appropriate coating amount.

The coating amount determination process will be described below with reference to the flowchart shown in FIG.
In the coating amount determination process, as shown in FIG. 8, the arithmetic processing unit 111 of the control unit 110 first executes a condition determination process for determining the control condition CC when the coating agent is applied to the printed circuit board P (S20). ).

In the condition determination process, first, the arithmetic processing unit 111 of the control unit 110 converts the coating condition DC input from the external input / output terminal 116 and the factor data FD in the plurality of coating information I stored in the storage unit 112. The comparison is performed, and the control condition CC when applying the coating agent is determined based on the comparison result.

In the present embodiment, since the priority PR is set for each factor F, the arithmetic processing unit 111 determines the factors in the coating condition DC and the plurality of coating information I based on the priority PR in each factor F. Compare with data FD. Further, the comparison between the coating condition DC and the factor data FD is performed in descending order of priority PR of factor F.

Specifically, as shown in FIG. 9, the arithmetic processing unit 111 selects the coating information (factor data FD) I having the factor value FV closest to the factor value FV of priority 1 in the coating condition DC. (S21). Then, the arithmetic processing unit 111 determines whether or not the coating information I selected by S21 is one (S22).

When there is only one coating information I (S22: YES), the control condition CC of the selected coating information I is determined as the control condition CC when the coating agent is applied (S23).

When there are a plurality of coating information I (S22: NO), the arithmetic processing unit 111 selects the coating information I having the factor value FV closest to the factor value FV of priority 2 in the coating condition DC (S24). ). Then, the arithmetic processing unit 111 determines whether or not the coating information I selected by S24 is one (S25).

When there is only one coating information I (S25: YES), the control condition CC of the selected coating information I is determined as the control condition CC when the coating agent is applied (S23).

When there are a plurality of coating information I (S25: NO), the arithmetic processing unit 111 selects the coating information I having the factor value FV closest to the factor value FV of priority 3 in the coating condition DC (S26). ). Then, the arithmetic processing unit 111 determines whether or not the coating information I selected by S26 is one (S27).

When there is only one coating information I (S27: YES), the control condition CC of the selected coating information I is determined as the control condition CC when the coating agent is applied (S23).

When there are a plurality of coating information I (S27: NO), the arithmetic processing unit 111 sets the control condition CC of the latest coating information I recently registered in the plurality of coating information I to the control condition CC when applying the coating agent. Determined as CC (S28).

Next, as shown in FIG. 8, the control unit 110 applies the coating agent to the roll paper 22 of the inspection device 20 based on the control condition CC determined in the condition determination process (S20) (S11). Then, the control unit 110 creates an image data IM of the coating agent applied to the roll paper 22 through the image processing unit 114. As shown in FIG. 4, the arithmetic processing unit 111 determines whether the coating amount of the coating agent is appropriate based on the spot SP of the coating agent applied to the image data IM (S12).

If the coating amount is not appropriate (S12: NO), change the CC of the coating agent control conditions (for example, syringe pressurization pressure, coating time, etc.) (S13) until the coating amount becomes appropriate in S11. To S13 are repeated.

When the coating amount is appropriate (S12: YES), the factor data FD when the coating amount is appropriate and the control condition CC thereof are stored in the storage unit 112 as coating information I (S14). As a result, the amount of the coating information I accumulated in the storage unit 112 increases, and the work efficiency of the coating amount determination process in the future can be improved.

The condition determination process in the coating amount determination process will be specifically described below with reference to Case A in FIG.
FIG. 10 shows a coating condition DC input from the external input / output terminal 116 and three coating information I in the storage unit 112.

The application condition DC is that the room temperature is 21 ° C., the remaining amount of the syringe is 8 cc, and the period after opening is 4 months. In addition, in FIG. 10 and later, the parentheses shown next to the factor value FV of the coating condition DC are not the data of the coating condition DC, but in order to make the explanation easy to understand, the permissible range of each factor is shown. It is added.

The three application information I are the syringe data 1 to the syringe data 3. The factor data FD of the syringe data 1 is that the room temperature is 20 ° C., the remaining amount of the syringe is 20 cc, and the period after opening is one month. The factor data FD of the syringe data 2 is that the room temperature is 20 ° C., the remaining amount of the syringe is 10 cc, and the period after opening is 3 months. The factor data FD of the syringe data 3 is that the room temperature is 30 ° C., the remaining amount of the syringe is 30 cc, and the period after opening is 0 month. As the priority management table T, the priority management table 1 is set.

Under such conditions, the control unit 110 executes the coating amount determining process, and determines the control condition CC for adjusting the coating amount to an appropriate coating amount by the condition determining process of S20.
In the condition determination process of S20, as shown in FIG. 9, the arithmetic processing unit 111 first executes the selection of S21.

In the selection of S21, the room temperature closest to the room temperature (priority 1) 21 ° C. of the coating condition DC is the room temperature 20 ° C. of the syringe data 1 and the syringe data 2, so that the arithmetic processing unit 111 can perform the syringe data 1 and Select the two application information I of the syringe data 2.

Next, the arithmetic processing unit 111 executes the determination of S22. In the determination of S22, two types of application information I, syringe data 1 and syringe data 2, are selected. Therefore, since the selected coating information is not one, the arithmetic processing unit 111 executes the selection of S24.

In the selection of S24, the remaining amount of the syringe closest to 8 cc of the remaining amount of the syringe (priority 2) of the application condition DC is 10 cc of the remaining amount of the syringe of the syringe data 2. Select only application information I.

Next, the arithmetic processing unit 111 executes the determination of S25. In the determination of S25, only the syringe data 2 is selected as the application information I. Therefore, the arithmetic processing unit 111 determines the control condition CC of the syringe data 2 selected in S25 as the control condition CC when applying the coating agent (S23).

That is, in the condition determination process, when the control condition CC of the syringe data 2 (application information I) having the factor value FV close to the factor value FV of the priority 1 and 2 in the priority management table 1 applies the coating agent. It is determined that the control condition CC is appropriate.

Further, since the application condition DC and the application information I of cases B to D shown in FIGS. 11 to 13 are processed by the same procedure as in case A of FIG. 10, each stage of the condition determination process (S21). , S24, S26), and the control condition CC (S23) determined in the condition determination process are shown in FIG. 14 together with Case A, and the detailed procedure of the condition determination process will be omitted.

As described above, in the condition determination process of the present embodiment, the control condition CC is determined based on the factor F in which the coating amount greatly fluctuates and the priority PR of the factor F. Therefore, for example, the priority is given to the factor F. A more appropriate control condition CC can be determined as compared with the case where PR is not set.

As a result, a coating amount close to an appropriate amount can be applied to the printed circuit board P, the working time of the adjustment work of applying the coating material to adjust the coating amount and the coating amount of the coating agent can be reduced, and the manufacturing cost can be increased. Can be suppressed.

As described above, the surface mounter 10 of the present embodiment adjusts the temperature of the coating agent, and inspects the dispenser 19 for applying the coating agent to the printed circuit board (object) P and the coating amount of the dispenser 19. Corresponds to the device 20 and a plurality of factor data FDs in which the factor value FVs of a plurality of factors F affecting the coating amount of the coating agent are set as a set, and each factor data FD of the plurality of factor data FDs. A storage unit 112 for storing a plurality of coating information I indicating a control condition CC for controlling the coating amount of the coating agent, and a control unit 110 are provided, and the control unit 110 is used when applying the coating agent. The control condition CC of the coating agent is determined based on the comparison result between the coating condition DC in which the factor values FV of the plurality of factors F are set as one set and the factor data FD of the plurality of coating information I in the storage unit 112. The condition determination process is executed, and the coating amount of the dispenser 19 to be applied based on the control condition CC determined in the condition determination process is inspected by the inspection device 20.

That is, the coating condition DC is compared with the factor data FDs in the plurality of coating information Is, the factor data FD similar to the coating condition DC is selected, and the coating agent is appropriately applied based on the plurality of coating information Is. The control condition CC for coating can be determined. That is, a coating agent close to an appropriate coating amount can be applied to the printed circuit board P. As a result, the working time of the adjustment work for adjusting the coating amount of the coating material and the coating amount of the coating agent can be reduced, and the increase in the manufacturing cost can be suppressed.

Further, a priority PR is set for each factor F, and in the condition determination process, the control unit 110 determines the factors in the coating condition DC and the plurality of coating information Is based on the priority PR in the factor F. Compare with data FD.

According to such a configuration, an appropriate control condition CC can be determined by comparing the coating condition DC with the factor data FD in the coating information I based on the priority PR of each factor F. That is, since the control condition CC can be determined based on the priority PR of the factor F in which the fluctuation of the coating amount is large (the influence on the coating amount is large), for example, when the priority PR is not set for each factor F. In comparison with, the factor data FD similar to the coating condition DC can be selected to determine a more appropriate control condition CC.

Further, in the condition determination process, the control unit 110 compares the factor data FD in the plurality of coating information I and the coating condition DC in descending order of priority PR of the factor F.

Among the plurality of factors F, the priority PR of the factor F in which the fluctuation of the coating amount is large is increased, and the coating condition DC and the factor data FD in the coating information I can be compared in descending order of the priority PR. As a result, for example, the factor data FD similar to the coating condition DC is selected in a short time as compared with the case where the control condition CCs of all the factors F are compared and the control condition CCs are rearranged and determined based on the priority PR. And the appropriate control condition CC can be determined.

Further, in the condition determination process, the control unit 110 selects the coating information I whose factor value FV of the factor data FD is close to the factor value FV of the coating condition DC from the plurality of coating information I, and selects the coating information I of the selected coating information I. The control condition CC is determined as the control condition CC of the coating agent.

That is, the control condition CC of the coating agent can be determined by a simple method of selecting the coating information I having a factor value FV close to the factor value FV of the coating condition DC. Therefore, for example, the coating information I is selected by a complicated process. The control condition CC of the coating agent can be easily determined as compared with the case of

Next, the second embodiment will be described with reference to FIGS. 10, 11, 13, 15, and 20.
The coating amount determination process in the second embodiment is to execute the narrowing process before the condition determination process in the first embodiment, and the configuration, action, and effect common to the first embodiment are duplicated. Is omitted. Further, the same reference numerals are used for the same configurations as in the first embodiment.

In the coating amount determination process of the second embodiment, as shown in the flowchart of FIG. 15, the arithmetic processing unit 111 of the control unit 110 executes a narrowing process for narrowing down the candidates for the coating information I before executing the condition determination process ( S30).

In the narrowing down process, as shown in the flowchart of FIG. 16, the factor value FV in the factor data FD selects the coating information I included in the permissible range R of the factor F in the coating condition DC from the plurality of coating information I.

In the present embodiment, the arithmetic processing unit 111 determines that the factor value FV in the factor data FD of the plurality of coating information I is the factor value of the coating condition DC with respect to the factor F of the priority 1, 2, 3 of the coating condition DC. Select one that is within the allowable range R of FV (S31). Then, the arithmetic processing unit 111 determines whether or not the coating information I selected by S31 exists (S32).

When the coating information I exists (S32: YES), the selected coating information I is determined as a candidate for the coating information I in the condition determination process (S33).

When the coating information I does not exist (S32: NO), the arithmetic processing unit 111 applies the factor values FV in the factor data FD of the plurality of coating information I for the factors F of the priority 1 and 2 of the coating condition DC. Select one that is within the permissible range R of the factor value FV of the time condition DC (S34). Then, the arithmetic processing unit 111 determines whether or not the coating information I selected by S34 exists (S35).

When the coating information I exists (S35: YES), the selected coating information I is determined as a candidate for the coating information I in the condition determination process (S33).

When the coating information I does not exist (S35: NO), the arithmetic processing unit 111 determines that the factor value FV in the factor data FD of the plurality of coating information I is the coating condition for the factor F having the priority 1 of the coating condition DC. The one within the permissible range R of the factor value FV of DC is selected (S36). Then, the arithmetic processing unit 111 determines whether or not the coating information I selected by S36 exists (S37).

When the coating information I exists (S37: YES), the selected coating information I is determined as a candidate for the coating information I in the condition determination process (S33).
When the coating information I does not exist (S37: NO), the arithmetic processing unit 111 determines all the coating information I as candidates for the coating information I in the condition determination process because there is no coating information I to select (S38).

Next, as shown in FIG. 15, the control unit 110 executes the condition determination process based on the coating information I determined in the narrowing process (S30) (S20).
Since the processes after the condition determination process (S20) are the same as those in the first embodiment, the description thereof will be omitted.

The narrowing process will be specifically described below with reference to Case A of FIG.
FIG. 10 shows a coating condition DC input from the external input / output terminal 116 and three coating information I in the storage unit 112.
The application condition DC is that the room temperature is 21 ° C., the remaining amount of the syringe is 8 cc, and the period after opening is 4 months.

The three application information I are the syringe data 1 to the syringe data 3. The factor data FD of the syringe data 1 is that the room temperature is 20 ° C., the remaining amount of the syringe is 20 cc, and the period after opening is one month. The factor data FD of the syringe data 2 is that the room temperature is 20 ° C., the remaining amount of the syringe is 10 cc, and the period after opening is 3 months. The factor data FD of the syringe data 3 is that the room temperature is 30 ° C., the remaining amount of the syringe is 30 cc, and the period after opening is 0 month. As the priority management table T, the priority management table 1 is set.

Under such conditions, the control unit 110 executes the coating amount determination process, and first narrows down the candidates for the coating information I used in the condition determination process by the narrowing process of S30.
In the narrowing down process of S30, as shown in FIG. 16, the arithmetic processing unit 111 first executes the selection of S31.

In case A, since only the room temperature, the remaining amount of the syringe, and the period after opening, which are the factors F of the syringe data 2, are within the allowable range R of the factor value FV of the application condition DC, the arithmetic processing unit 111 of the syringe data 2 Select application information I.

Next, the arithmetic processing unit 111 executes the determination of S32. In the determination of S32, since the syringe data 2 exists as the coating information I, the arithmetic processing unit 111 determines only the syringe data 2 selected in S31 as a candidate for the coating information I in the condition determination process.

That is, in the narrowing process, the room temperature, the remaining amount of the syringe, and the period after opening, which are the factors F of the priority 1, 2, and 3 of the application condition DC, are the room temperature, the remaining amount of the syringe, and the remaining amount after opening, which are the factors F of the syringe data 2. Since only the period is within the permissible range R of the factor value FV of the application condition DC, only the syringe data 2 is determined as a candidate for the application information I in the condition determination process.

Further, in the narrowing down process, the coating condition DC and the coating information I of Case B, Case D, and Case E to Case G shown in FIGS. 11, 13, and 17 to 19 are subjected to the same procedure as in FIG. Since the processing is performed, the coating information I selected in each stage of the narrowing process (S31, S34, S36) and the coating information I (S33) determined in the narrowing process are shown in FIG. 20 together with the case A, and the narrowing process is performed. Detailed procedure of is omitted. Note that FIG. 20 also shows the coating information I of each stage (S21, S24, S26) of the condition determination process executed after the narrowing process and the control condition CC (S23) determined in the condition determination process.

As described above, in the control unit 110 of the surface mounter 10 of the present embodiment, among the plurality of coating information I, the factor value FV in the factor data FD is included in the allowable range R of the factor value FV in the coating condition DC. The narrowing down process for selecting the coating information I to be performed is executed, and the condition determination process is executed after the narrowing down process is executed.

That is, in the narrowing down process, by setting the permissible range R for the factor value FV of each factor F and selecting the coating information I similar to the coating condition DC, the coating information I to be compared with the coating condition DC is compared. The number can be reduced. As a result, the processing time in the condition determination process can be shortened, so that the working time of the adjustment work and the application amount of the coating agent can be further reduced.

<Embodiment 3>
Next, the third embodiment will be described with reference to FIGS. 21 to 23.
The coating amount determining process in the third embodiment switches the priority management table T based on the expiration date DL1 of the coating agent and the priority switching deadline DL2 before the narrowing-down process in the second embodiment. Since the configurations, actions, and effects common to the above are duplicated, the description thereof will be omitted. Further, the same reference numerals are used for the same configurations as in the second embodiment.

In the coating amount determination process of the third embodiment, as shown in the flowchart of FIG. 21, the arithmetic processing unit 111 of the control unit 110 first determines the switching of the priority management table T based on the priority switching deadline DL2 of the coating agent. I do.

In the switching determination, when the period after opening the coating agent has passed within the priority switching deadline DL2, the arithmetic processing unit 111 changes the priority PR of the period after opening the coating agent to the highest state and narrows down. Execute the process.

In the present embodiment, the arithmetic processing unit 111 changes the priority PR of the period after opening the coating agent by changing the priority management table T.
Specifically, as shown in FIG. 21, the arithmetic processing unit 111 first determines whether or not the period after opening the coating agent is within the priority switching deadline DL2 of the table switching determination table stored in the storage unit 112. Judgment (S41).

When the period after opening is within the priority switching deadline DL2 (S41: YES), the priority management table 1 is selected (S42), and the narrowing process of S30 is executed. Since the processing after the narrowing down processing (S30) is the same as that of the second embodiment, it is omitted.

When the period after opening has passed the priority switching deadline DL2 (S41: NO), whether or not the period after opening the coating agent is within the expiration date DL1 of the table switching determination table stored in the storage unit 112. Judgment (S43).

When the period after opening is within the expiration date DL1 (S43: YES), the priority management table 2 is selected (S44), and the narrowing process of S30 is executed. Since the processing after the narrowing down processing (S30) is the same as that of the second embodiment, it is omitted.

When the period after opening has passed the expiration date DL1 (S43: NO), the operator is notified through the external input / output terminal 116 that the period after opening the coating agent has passed the expiration date DL1 (S45). .. The notified operator, for example, replaces the coating agent with a new one and executes the coating amount determination process, or selects the priority management table 2 and executes the narrowing down process (S30), based on the notification information. Continue the adjustment work.

The process of switching the priority management table T based on the table switching determination table will be specifically described below with reference to the three coating condition DCs and the three coating information I shown in FIG.
The application condition α in FIG. 22 is that the room temperature is 20 ° C., the remaining amount of the syringe is 30 cc, and the period after opening is 4 months.

In the syringe data 1 of the three application information I, the room temperature in the factor data FD is 30 ° C., the remaining amount of the syringe is 31 cc, and the period after opening is 3 months. In the syringe data 2, the room temperature in the factor data FD is 25 ° C., the remaining amount of the syringe is 35 cc, and the period after opening is 6 months. In the syringe data 3, the room temperature in the factor data FD is 21 ° C., the remaining amount of the syringe is 40 cc, and the period after opening is one month.

Under such conditions, when the arithmetic processing unit 111 of the control unit 110 executes the determination process of S41, in the determination of S41, the three months after opening under the application condition α is 5 of the priority switching deadline DL2. Judged as within a month. Then, the arithmetic processing unit 111 selects the priority management table 1 in S42.

In the case of the application condition β, the room temperature is 20 ° C., the remaining amount of the syringe is 30 cc, and the period after opening is 6 months.
Under such a condition, when the arithmetic processing unit 111 executes the determination process of S41, in the determination of S41, the 6 months after opening under the coating condition β has passed 5 months of the priority switching deadline DL2. Judge that it is. Therefore, the arithmetic processing unit 111 executes the determination process of S43.

In the determination of S43, it is determined that the 6 months after opening under the application condition β is within 6 months of the expiration date DL1. Then, the arithmetic processing unit 111 selects the priority management table 2 in S44.
In the case of the application condition γ, the room temperature is 20 ° C., the remaining amount of the syringe is 30 cc, and the period after opening is 7 months.

Under such a condition, when the arithmetic processing unit 111 executes the determination process of S41, in the determination of S41, the 7 months after opening under the application condition γ has passed 5 months of the priority switching deadline DL2. Judge that it is. Further, in the determination of S43, it is determined that the 7 months after opening under the application condition γ has passed the 7 months of the expiration date DL1. Therefore, the arithmetic processing unit 111 notifies the operator that the expiration date DL1 has passed after the opening of the coating agent in S45. When the operator selects the priority management table 2 and continues the coating amount determination process after the notification, the subsequent processing is the same as the coating condition β.

Information on each stage after the switching process of the priority management table T under the coating conditions α, β, and γ is shown in FIG. 23 together with the result selected in the switching process.

As described above, according to the present embodiment, one factor F among the plurality of factors F is the period after opening the coating agent, and the coating agent has an expiration date DL1 and a predetermined time before the expiration date DL1. When the priority switching deadline DL2 set to is set to, and the period after opening the coating agent has passed the priority switching deadline DL2, the control unit 110 gives priority to the period after opening the coating agent. The PR is changed to the highest state, and after the change, the narrowing process and the condition determination process are executed.

For example, when the room temperature is high and the coating agent is easily deteriorated, or when a coating agent which is easily deteriorated is used, the period after opening the coating agent (elapsed period after opening) is a factor F for a large fluctuation in the coating amount. Therefore, when the period after opening is a predetermined time before the expiration date DL1 of the coating agent, that is, when the period after opening is close to the expiration date DL1 of the coating agent, the priority PR of the time after opening the coating agent is set to the highest state. Therefore, an appropriate control condition CC can be determined according to the altered coating agent.

Further, the storage unit 112 stores a plurality of priority management tables T indicating the priority PR of each factor F, and the control unit 110 changes the priority management table T after opening the coating agent. Change the priority PR of the period.

For example, the priority management table T showing the priority PR of the factor F in the normal state, the priority management table T showing the priority PR of the factor F when the expiration date DL1 is approached, and the like are stored in the storage unit 112. deep. Then, the priority management table T is changed depending on whether or not the priority switching deadline DL2 has passed after the opening of the coating agent. That is, the priority PR can be changed according to the condition of the coating agent before and after the deterioration of the coating agent, and an appropriate control condition CC can be determined according to the condition of the coating agent.

Further, the control unit 110 notifies when the expiration date DL1 has passed after the opening of the coating agent.
That is, before executing the comparison process or the narrowing-down process, the operator can be notified that the expiration date DL1 has passed, and the operator can quickly confirm whether or not the coating agent can be used. As a result, for example, it is possible to avoid applying an excessively altered coating agent, and it is possible to reduce the working time of the adjustment work and the coating amount of the coating agent.
