JP-A-2006-55853

By the way, in general, liquids used for dripping or coating may change their states such as viscosity and volume depending on, for example, room temperature, the pressure applied to the dispenser due to the remaining amount of liquid, and the elapsed time after opening the liquid (period after opening). changes. For this reason, even when the temperature of the liquid is controlled, factors other than the temperature of the liquid cause variations in the amount of liquid to be dropped and the application area, and stringiness of the liquid. Therefore, in order to adjust the amount of liquid output, it is actually necessary to perform adjustment work such as inspecting the amount of liquid output multiple times. Manufacturing costs increase.

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

A coating device disclosed in this specification is a coating device that applies a coating agent to an object, comprising: a dispenser that adjusts the temperature of the coating agent and applies the coating agent to the object; an inspection device for inspecting the coating amount of the coating agent, a plurality of factor data having a set of factor values of a plurality of factors that affect the coating amount of the coating agent, and each factor data among the plurality of factor data a plurality of pieces of application information indicating control conditions for controlling the application amount of the coating agent corresponding to the above; condition determination for determining the control condition of the coating agent based on a result of comparison between a set of factor values of a plurality of factors and a condition at the time of coating, and the factor data of the plurality of coating information stored in the storage unit; processing, and the inspection device inspects the coating amount of the dispenser to be coated based on the control conditions determined in the condition determination processing.

Further, the technology disclosed in this specification is a surface mounter comprising the coating device, the conveying device that conveys the object, the dispenser, and a mounting head that mounts an electronic component on the object. and a component mounting apparatus having

According to such a coating device, the coating conditions are compared with the factor data in the plurality of coating information, the factor data similar to the coating conditions are selected, and appropriate control conditions are determined based on the plurality of coating information. can decide. That is, it is possible to apply the coating agent to the object in an amount close to an appropriate coating amount. As a result, it is possible to reduce the working time and the amount of the coating material to be applied for the adjustment work of applying the coating material and adjusting the coating amount, and to suppress the increase in the manufacturing cost.

The coating device disclosed by this specification may be configured as follows.
A priority is set for each of the factors, and in the condition determination process, the control unit controls the factor data in the application time condition and the plurality of application information based on the priority in the factor. and may be compared.
According to such a configuration, it is possible to determine an appropriate control condition by comparing the factor data in the application information with the condition at the time of application based on the priority of each factor.

In other words, since the control conditions can be determined based on the priority of factors with large fluctuations in coating amount, for example, factor data similar to the conditions at the time of coating can be selected compared to the case where no priority is set for each factor. can determine more appropriate control conditions.

In the condition determination process, the control unit may compare the factor data in the plurality of pieces of application information and the conditions at the time of application in descending order of the priority of the factor.
According to such a configuration, it is possible to give higher priority to a factor having a large variation in coating amount among a plurality of factors, and to compare the coating conditions and the factor data in the coating information in descending order of priority. As a result, for example, compared with the case where the control conditions for all factors are compared and the control conditions are sorted and determined based on the priority, factor data similar to the coating conditions can be selected in a short period of time, and appropriate control conditions can be obtained. can be determined.

In the condition determination process, the control unit selects, from the plurality of pieces of application information, the application information in which the factor value of the factor data is close to the factor value of the application time condition, and selects the selected application information. A control condition may be determined as the control condition for the coating agent.

According to such a configuration, since the coating agent control condition can be determined by a simple method of selecting coating information having a factor value close to the factor value of the coating condition, for example, coating information can be selected by a complicated process. As compared with the case, it is possible to easily determine the control conditions of the coating material.

An allowable range is set for each of the factors, and the control unit controls that, among the plurality of application information, the factor value in the factor data is included in the allowable range of the factor value in the application time condition. A narrowing process for selecting the application information to be applied may be executed, and the condition determining process may be executed after the narrowing process is executed.

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

One of the plurality of factors is a period after opening of the coating agent, and the coating agent has an expiration date and a priority switching expiration date set a predetermined time before the expiration date. is set, and the control unit changes the priority of the period after opening of the coating agent to the highest state when the period after opening of the coating agent has passed the priority switching time limit. Then, the condition determining process or the narrowing process may be executed after the change.

For example, when the room temperature is high and the coating agent easily degrades, or when a coating agent that easily degrades is used, the period after opening the coating agent (elapsed time after opening) causes a large fluctuation in the coating amount. Therefore, when the period after opening is a predetermined time before 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 of the coating agent is set to the highest priority. Appropriate control conditions can be determined according to the changed 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 period after opening of the coating material. The configuration may be such that the priority is changed.

According to such a configuration, for example, a priority management table indicating the priority of factors in normal times, a priority management table indicating the priority of factors when the expiration date is approaching, etc. are stored in the storage unit. . Then, the priority management table is changed depending on whether or not the period after opening the coating agent has passed the priority switching time limit. In other words, the priority can be changed in accordance with the state of the coating agent before and after the coating agent deteriorates, and appropriate control conditions can be determined in accordance with the state of the coating agent.

The control unit may be configured to notify when the period after opening of the coating agent has passed the expiration date.
According to such a configuration, it is notified that the coating agent has passed its expiration date, and the operator can quickly confirm whether or not the coating agent can be used before executing the comparison process or the narrowing process. As a result, for example, application of an excessively degraded coating agent can be avoided, and the working time of the adjustment work and the coating amount of the coating agent can be reduced.

According to the present disclosure, it is possible to reduce the working time of the adjustment work and the application amount of the coating agent.

The expiry date DL1 of the coating agent is a deadline that must be confirmed in order to use the coating agent. The priority switching deadline DL2 is a deadline set a predetermined period before the expiration date DL1 of the coating agent. Specifically, the priority switching deadline DL2 of the coating agent with the expiration date of six months is five months, which is one month before the expiration date DL1. As shown in FIGS. 6 and 7, the expiration date DL1 and the priority switching expiration date DL2 of the coating agent are managed by a table switching determination table JT together with a priority management table T for use within the respective expiration dates.

The table switching determination table JT of this embodiment indicates 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 usage deadline DL1. is shown to be used.

A plurality of factors F that change the coating amount of the coating agent include, for example, the room temperature, the amount of coating agent remaining in the syringe 19A, and the period after opening the coating agent (elapsed period after opening). These factors F are considered to be factors F that are difficult to control compared to the control condition CC. A set of factor values FV of these difficult-to-control factors F is set as factor data FD.

As shown in FIG. 10, the application 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 application amount of the application agent to an appropriate amount.

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

Further, the factor data FD of the syringe data 2 in the application information I of case A has a temperature of 20° C., a syringe remaining amount of 10 cc, and a period of 3 months after opening. The control conditions CC for appropriate control are AAA for the syringe, NNN for the nozzle, 0.20 for the syringe pressurization 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 factors F that are difficult to control are set. The priority PR of each factor F is set to a high value when the factor value FV of the factor F changes to greatly change the coating amount of the coating agent.
In this embodiment, as shown in FIG. 7, the storage unit 112 stores two priority management tables T, a priority management table 1 and a priority management table 2 . As the priority management table T, the priority management table 1 is normally used. For a coating agent that easily deteriorates, two priority management tables T are switched for use based on the table switching determination table JT.

In the priority management table 1, as shown in FIG. 7, the highest priority PR is assigned priority 1, and the room temperature, syringe remaining amount, and post-opening period are set in descending order of priority. In the priority management table 1, the allowable range R of the room temperature is ±3° C., the allowable range R of the syringe remaining amount is ±2 cc, and the allowable range R of the post-opening period is ±2 months.

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

The driving control unit 113 drives the conveying device 12, the driving device 17, the inspection device 20, and the like according to instructions from the arithmetic processing unit 111. FIG.

The component supply control unit 115 controls the component supply device 14 according to commands from the arithmetic processing unit 111 .
The external input/output terminal 116 includes input devices such as a touch panel, keyboard, and mouse, and output devices such as a display. For example, the operator confirms various information displayed on the output device and operates the input device to instruct the control unit 110 . In the present embodiment, the operator inputs from the external input/output terminal 116 the application conditions DC when applying the application agent to the printed circuit board P and the like.

Here, the application condition DC input by the operator is the factor F that makes it difficult for the operator to control. In this embodiment, the factor F of the condition DC at the time of application is the room temperature, the residual 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 in the storage unit 112 . The arithmetic processing unit 111 drives and controls the transport device 12 and the component mounting device 13 via the drive control unit 113, for example, based on the mounting program in the storage unit 112. FIG. It also controls the component supply device 14 via the component supply control unit 115 .

Further, the arithmetic processing unit 111 determines control conditions CC for 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 optimum application amount of the coating agent is determined by applying the coating agent to the inspection device 20 a plurality of times. Then, the arithmetic processing unit 111 applies the application amount of the application agent determined by the application amount determination program to the printed circuit board P according to the application agent application program stored in the storage unit 112 .

The application amount determination process for determining the application amount of the coating agent by the application amount determination program will be described below.
In general, a coating agent such as cream solder or adhesive for mounting the electronic component EL on the printed circuit board P is output from the output port of the dispenser 19 in a hemispherical shape. The dispenser 19 descends toward the printed circuit board P in a state where the coating agent has been output, so that the printed circuit board P is coated with the coating agent in dots.

However, the viscosity and volume of the coating material change depending on the room temperature, the pressure applied to the dispenser 19 due to the remaining amount of the coating material, and the period after the opening of the coating material.
Therefore, even when controlling the temperature of the coating material, factors other than the temperature of the coating material (room temperature, remaining amount of coating material, period after opening the package, etc.) may cause variations in the amount of coating material applied, or cause threads in the coating material. Pulling may occur. For this reason, in order to adjust the coating amount of the coating agent, adjustment operations such as actually coating the coating agent and inspecting the coating amount are performed a plurality of times. As a result, the working time for the adjustment work and the coating amount of the coating agent increase, resulting in an increase in the manufacturing cost.

Therefore, in the present embodiment, the control unit 110 executes the application amount determination process in the application amount determination program by the arithmetic processing unit 111, and determines the control condition CC for making the application amount of the coating agent appropriate.

The application amount determination process will be described below with reference to the flowchart shown in FIG.
In the application 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 conditions CC when applying the coating agent to the printed circuit board P (S20 ).

In the condition determination process, first, the arithmetic processing unit 111 of the control unit 110 determines the application condition DC input from the external input/output terminal 116 and the factor data FD in the plurality of pieces of application information I stored in the storage unit 112. A control condition CC for applying the coating material is determined based on the comparison result.

In the present embodiment, a priority PR is set for each factor F. Therefore, based on the priority PR for each factor F, the calculation processing unit 111 Compare with data FD. Further, the comparison between the application time conditions DC and the factor data FD is performed in descending order of the priority PR of the factor F. FIG.

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

If there is one coating information I (S22: YES), the control condition CC of the selected coating information I is determined as the control condition CC for coating the coating material (S23).

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

If there is one application information I (S25: YES), the control condition CC of the selected application information I is determined as the control condition CC for applying the application agent (S23).

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

If there is one application information I (S27: YES), the control condition CC of the selected application information I is determined as the control condition CC for applying the application agent (S23).

If there is a plurality of application information I (S27: NO), the arithmetic processing unit 111 sets the control condition CC of the latest application information I recently registered in the plurality of application information I to the control condition when applying the application agent. It is 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 conditions CC determined in the condition determination process (S20) (S11). Then, the control unit 110 creates 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 spots SP of the coating agent applied to the image data IM (S12).

If the coating amount is not appropriate (S12: NO), the coating agent control conditions (for example, syringe pressurization pressure, coating time, etc.) are changed (S13), and S11 is continued until the coating amount becomes appropriate. to S13 are repeated.

If the application amount is appropriate (S12: YES), the factor data FD and the control conditions CC when the application amount is appropriate are stored in the storage unit 112 as application information I (S14). As a result, the amount of application information I accumulated in the storage unit 112 is increased, and the working efficiency of future application amount determination processing can be improved.

Condition determination processing in the application amount determination processing will be specifically described below with reference to case A in FIG.
FIG. 10 shows application conditions DC input from the external input/output terminal 116 and three pieces of application information I in the storage unit 112 .

The condition DC at the time of application is a room temperature of 21° C., a syringe remaining amount of 8 cc, and a period of 4 months after opening. In FIG. 10 and subsequent figures, the parentheses shown next to the factor value FV of the application condition DC are not the data of the application condition DC, but to make the explanation easier to understand, the allowable range of each factor is indicated. It is attached.

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

Under such conditions, the control unit 110 executes the application amount determination process, and determines the control condition CC for making the application amount of the coating agent appropriate by the condition determination 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 application condition DC is the room temperature of 20 ° C. of the syringe data 1 and the syringe data 2. Two pieces of application information I of syringe data 2 are selected.

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

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

Next, the arithmetic processing unit 111 executes the determination of S25. In the determination of S25, only the syringe data 2 is selected for 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 for 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 priorities 1 and 2 in the priority management table 1 applies the coating agent is determined to be appropriate as the control condition CC of .

11 to 13, the application time conditions DC and application information I for cases B to D shown in FIGS. 11 to 13 are processed by the same procedure as for case A in FIG. , S24, S26) and the control conditions CC (S23) determined in the condition determination process are shown in FIG.

As described above, in the condition determination process of the present embodiment, the control condition CC is determined based on the factor F that greatly fluctuates the coating amount and the priority PR of 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, it is possible to apply an application amount close to an appropriate amount to the printed circuit board P, reduce the working time and the application amount of the application material for the adjustment work of applying the application material and adjusting the application amount, and furthermore, increase the manufacturing cost. can be suppressed.

As described above, the surface mounter 10 of the present embodiment adjusts the temperature of the coating agent, the dispenser 19 that applies the coating agent to the printed circuit board (object) P, and the inspection device that inspects the coating amount of the dispenser 19. Corresponding to the device 20, a plurality of factor data FD having a set of factor values FV of a plurality of factors F affecting the application amount of the coating agent, and each factor data FD among the plurality of factor data FD a storage unit 112 for storing a plurality of pieces of application information I indicating control conditions CC for controlling the application amount of the applied coating agent; A coating agent control condition CC is determined based on a result of comparison between a set of factor values FV of a plurality of factors F and factor data FD of a plurality of application information I stored in a storage unit 112 and application conditions DC. A condition determination process is executed, and the inspection device 20 inspects the coating amount of the dispenser 19 to be applied based on the control conditions CC determined in the condition determination process.

That is, the application time condition DC is compared with factor data FD in a plurality of pieces of application information I, factor data FD similar to the application time condition DC is selected, and the application agent is appropriately applied based on the plurality of pieces of application information I. Control conditions CC for coating can be determined. In other words, the printed circuit board P can be coated with the coating agent in an amount close to an appropriate coating amount. As a result, it is possible to reduce the working time of the adjustment work for adjusting the application amount of the application material and the application amount of the application agent, and to suppress an increase in the manufacturing cost.

A priority PR is set for each factor F. In the condition determination process, the control unit 110 determines factors in the application time condition DC and the plurality of application information I based on the priority PR in the factor F. Compare with data FD.

According to such a configuration, it is possible to determine an appropriate control condition CC by comparing the application condition DC and the factor data FD in the application 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 that has a large variation in the coating amount (has a large effect on the coating amount), for example, if the priority PR is not set for each factor F By selecting the factor data FD similar to the application time condition DC, it is possible to determine a more appropriate control condition CC.

In addition, in the condition determination process, the control unit 110 compares the factor data FD in the plurality of pieces of application information I with the application conditions DC in descending order of the priority PR of the factor F. FIG.

Among a plurality of factors F, the factor data FD in the application information I can be compared with the application time condition DC and the factor data FD in the application information I by increasing the priority PR of the factor F having a large variation in the coating amount. As a result, for example, compared with the case where the control conditions CC of all the factors F are compared and the control conditions CC are arranged and determined based on the priority PR, the factor data FD similar to the application conditions DC can be selected in a short time. and the appropriate control conditions CC can be determined.

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

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

<Embodiment 2>
Next, Embodiment 2 will be described with reference to FIGS. 10, 11, 13, 15 and 20. FIG.
The coating amount determination process in the second embodiment executes the narrowing down process before the condition determination process in the first embodiment, and the configurations, actions, and effects that are common to the first embodiment overlap, so the description thereof will be omitted. omitted. Moreover, the same code|symbol shall be used about the same structure as Embodiment 1. FIG.

In the application 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 candidates for the application information I before executing the condition determination process ( S30).

In the narrowing process, as shown in the flowchart of FIG. 16, the application information I whose factor value FV in the factor data FD is within the allowable range R of the factor F in the application condition DC is selected from a plurality of pieces of application 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 application information I is the factor value of the application condition DC Those within the allowable range R of FV are selected (S31). Then, the arithmetic processing unit 111 determines whether or not the application information I selected in S31 exists (S32).

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

If the application information I does not exist (S32: NO), the arithmetic processing unit 111 determines that the factor value FV in the factor data FD of the plurality of application information I is the factor F with the priority levels 1 and 2 of the application time condition DC. A factor value FV of the time condition DC within the allowable range R is selected (S34). Then, the arithmetic processing unit 111 determines whether or not the application information I selected in S34 exists (S35).

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

If the application 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 application information I for the factor F of priority 1 of the application condition DC is equal to the application condition A DC factor value FV within the allowable range R is selected (S36). Then, the arithmetic processing unit 111 determines whether or not the application information I selected in S36 exists (S37).

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

Next, as shown in FIG. 15, the control unit 110 executes condition determination processing (S20) based on the application information I determined in the narrowing processing (S30).
Since the processing after the condition determination processing (S20) is the same as in the first embodiment, the description is omitted.

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

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

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

In case A, only the room temperature, the remaining syringe amount, and the period after opening, which are the factors F of the syringe data 2, are within the allowable range R of the factor values FV of the application conditions DC. Application information I is selected.

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

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

11, 13, and 17 to 19, the application time conditions DC and application information I for cases B, D, and E to G shown in FIGS. Application information I selected at each stage (S31, S34, S36) of the narrowing process and application information I (S33) determined in the narrowing process are shown in FIG. We omit the detailed procedures of FIG. 20 also shows the application information I at 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, the control unit 110 in the surface mounter 10 of the present embodiment determines that the factor value FV in the factor data FD among the plurality of pieces of application information I is included in the allowable range R of the factor value FV in the application condition DC. A narrowing-down process for selecting the application information I to be applied is executed, and after the narrowing-down process is executed, a condition determination process is executed.

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

<Embodiment 3>
Next, Embodiment 3 will be described with reference to FIGS. 21 to 23. FIG.
The coating amount determination process in the third embodiment switches the priority management table T based on the expiration date DL1 and the priority switching expiration date DL2 of the coating agent before the narrowing down process in the second embodiment. Since the configurations, actions, and effects that are common to , are redundant, descriptions thereof will be omitted. Also, 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. I do.

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

If 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, the description thereof will be omitted.

If the period after opening has passed the priority switching deadline DL2 (S41: NO), it is determined 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. Determine (S43).

If 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, the description thereof will be omitted.

If the period after opening has passed the expiration date DL1 (S43: NO), the worker is notified through the external input/output terminal 116 that the period after opening the application agent has passed the expiration date DL1 (S45). . Based on the notified information, for example, the notified operator 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 process (S30). Continue adjustment work.

Processing for switching the priority management table T based on the table switching determination table will be specifically described below with reference to three coating conditions DC and three coating information I shown in FIG.
22, the room temperature is 20° C., the syringe remaining amount is 30 cc, and the period after opening is 4 months.

Syringe data 1 of the three pieces of application information I has a room temperature of 30° C., a syringe remaining amount of 31 cc, and a period of 3 months after opening in the factor data FD. In the syringe data 2, the room temperature in the factor data FD is 25° C., the syringe remaining amount 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 syringe remaining amount 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 of the period after opening in the application time condition α is 5 of the priority switching deadline DL2. Determined within a month. Then, the arithmetic processing unit 111 selects the priority management table 1 in S42.

In the case of the application time condition β, the room temperature is 20° C., the syringe remaining amount is 30 cc, and the period after opening is 6 months.
Under these conditions, when the arithmetic processing unit 111 executes the determination process of S41, in the determination of S41, the six months of the period after opening in the application time condition β have passed the five months of the priority switching deadline DL2. It is determined that Therefore, the arithmetic processing unit 111 executes the determination processing of S43.

In the determination of S43, it is determined that the six months after opening under the condition β at the time of application is within six 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 syringe remaining amount is 30 cc, and the period after opening is 7 months.

Under these conditions, when the arithmetic processing unit 111 executes the determination process of S41, in the determination of S41, the 7 months of the period after opening in the application time condition γ have passed the priority switching deadline DL2 of 5 months. It is determined that In addition, in the determination of S43, it is determined that the 7 months of the period after opening under the condition γ at the time of application has passed the expiration date DL1 of 7 months. Therefore, the arithmetic processing unit 111 notifies the operator that the period after opening the coating agent has passed the expiration date DL1 in S45. After the notification, if the operator selects the priority management table 2 and continues the application amount determination processing, the subsequent processing is the same as the application time condition β.

FIG. 23 shows the information of each stage after the switching process of the priority management table T for the coating conditions α, β, and γ together with the results 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 of the coating agent, and the coating agent has the expiration date DL1 and a predetermined time before the expiration date DL1. is set, and the control unit 110 sets the priority of the period after opening the coating agent when the period after opening the coating agent has passed the priority switching deadline DL2. 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 degraded, or when a coating agent that is easily degraded is used, the period after opening the coating agent (elapsed time after opening) is a factor F that causes a large variation 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 in accordance with the degraded 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 to change the Change the priority PR of the period.

For example, the storage unit 112 stores a priority management table T indicating the priority PR of the factor F during normal operation, a priority management table T indicating the priority PR of the factor F when the expiration date DL1 is approaching, and the like. back. Then, the priority management table T is changed depending on whether or not the period after opening the coating agent has passed the priority switching time limit DL2. In other words, the priority PR can be changed according to the condition of the coating material before and after the coating material deteriorates, and an appropriate control condition CC can be determined according to the condition of the coating material.

Moreover, the control part 110 alert|reports, when the period after opening of coating agent has passed expiration date DL1.
In other words, the operator is notified that the expiration date DL1 of the coating agent has passed before executing the comparison process or the narrowing process, so that the operator can quickly confirm whether or not the coating material can be used. As a result, for example, application of an excessively degraded coating agent can be avoided, and the working time of the adjustment work and the coating amount of the coating agent can be reduced.
