<Configuration: Component Mounting System 1>
A configuration of the component mounting system 1 will be described with reference to FIGS. 1 to 3. FIG.

FIG. 1 is a configuration explanatory diagram of a component mounting system 1 according to an embodiment. FIG. 2 is a plan view showing component mounting apparatuses M4 and M5 used in the component mounting system 1 according to the embodiment. 3 is a partial cross-sectional view of the component mounting apparatuses M4 and M5 used in the component mounting system 1 taken along line III-III in FIG.

As shown in FIG. 1, a component mounting system 1 has a function of mounting components (electronic components) on boards to produce mounted boards, and has functions of supplying, delivering and collecting boards to be mounted. have. The component mounting system 1 may be an example of a skill evaluation system.

The component mounting system 1 includes a component mounting line 1a, a management device 3a, a component storage 3b, and an operator terminal 3c.

The component mounting line 1a includes a substrate supply device M1, a substrate transfer device M2, a solder printing device M3, which is a plurality of devices for mounting electronic components, component mounting devices M4 and M5, a reflow device M6, and a substrate recovery device M7. are connected in series in this order. Each device from the substrate supply device M1 to the substrate recovery device M7 is connected via a communication network 2 to a management device 3a having a management computer. The component mounting apparatuses M4 and M5 are examples of production apparatuses. Note that the component mounting line 1a may be an example of a production apparatus.

In the component mounting work, as shown in FIGS. 1 to 3, components are applied to the board 6 conveyed along the component mounting line 1a by the solder printing device M3, the component mounting devices M4 and M5, and the reflow device M6. Parts mounting work for mounting is performed. That is, the substrate 6 supplied by the substrate supply device M1 is carried into the solder printing device M3 via the substrate delivery device M2, where the solder printing work of screen-printing the solder for joining the components onto the substrate 6 is performed.

The solder-printed board 6 is sequentially delivered to the component mounting apparatuses M4 and M5, and the component mounting work of mounting components on the board 6 after solder printing is performed. The substrate 6 after mounting the components is carried into the reflow device M6 and heated according to a predetermined heating profile to melt and solidify the solder for joining the components. As a result, the component is solder-bonded to the board 6 to complete the mounting board in which the component is mounted on the board 6, which is collected by the board collecting device M7.

Next, the component mounting apparatuses M4 and M5 will be described with reference to FIGS. 2 and 3. FIG.

As shown in FIGS. 2 and 3, the component mounting apparatuses M4 and M5 of the present embodiment include a base 4, a board transfer section 5, a component supply section 7, a Y-axis moving table 10, an X-axis moving table 11, a mounting A head 12, a component recognition camera 9, and a board recognition camera 14 are provided.

The base 4 is capable of disposing the substrate 6, the substrate transfer unit 5, and the like. The base 4 is provided with a substrate transfer section 5 extending along the X-axis direction on its upper surface.

The board transfer unit 5 positions and holds the board 6 at the mounting position by transferring the board 6 received from the upstream device. Component supply units 7 are arranged on both sides of the substrate transport unit 5 in the Y-axis direction.

The component supply unit 7 is a structure for the mounting head 12 to pick up components, in other words, for supplying components to the mounting head 12 . A plurality of tape feeders 8 are installed side by side in the component supply section 7 . The tape feeder 8 pitch-feeds the carrier tape 17, which is a container containing the components, so that the mounting head 12 constituting the component mounting mechanism can position the components at the mounting position.

A long Y-axis moving table 10 is arranged substantially horizontally along the Y-axis direction at one end of the upper surface of the base 4 on the X-axis plus direction side. A pair of elongated X-axis moving tables 11 are mounted on the Y-axis moving table 10 so as to be slidable along the Y-axis direction.

One of the pair of X-axis moving tables 11 is disposed on the Y-axis plus direction side with respect to the substrate transport section 5, and the other of the pair of X-axis moving tables 11 is disposed with respect to the substrate transport section 5 on the Y-axis side. It is arranged on the negative direction side. Also, the pair of X-axis moving tables 11 are arranged substantially horizontally along the X-axis direction.

A pair of X-axis moving tables 11 can be moved in the Y-axis direction by a linear drive mechanism of the Y-axis moving table 10 . A mounting head 12 is slidably mounted on each of the pair of X-axis moving tables 11 .

The mounting head 12 is a multiple head having a plurality of holding heads, and suction nozzles 12a that can individually lift and hold components by suction are attached to the lower ends of the respective holding heads. Also, the mounting head 12 can be moved along the X-axis direction by a linear driving mechanism of the X-axis moving table 11 .

By driving the Y-axis moving table 10 and the X-axis moving table 11 by driving the linear driving mechanism, the mounting head 12 can be freely moved on the XY plane. As a result, the mounting head 12 sucks and picks up the components from the tape feeders 8 arranged in the respective component supply units 7 by means of the plurality of suction nozzles 12a, moves the components above the board 6, and mounts the components on the board 6. Install in position. The Y-axis moving table 10 , the X-axis moving table 11 and the mounting head 12 constitute a component mounting mechanism 13 .

A component recognition camera 9 is arranged on the base 4 between the board transfer unit 5 and each component supply unit 7 . When the mounting head 12 that has picked up the component from the component supply unit 7 passes above the component recognition camera 9, the component recognition camera 9 detects the plurality of components mounted on the mounting head 12 at the imaging timing when the mounting head 12 passes. An image of a component held by a predetermined suction nozzle 12a out of the suction nozzles 12a is taken. Therefore, the component recognition camera 9 can recognize a component sucked by a predetermined suction nozzle 12a among the plurality of suction nozzles 12a.

Further, when the component recognition camera 9 recognizes the component sucked by the suction nozzle 12a and the tip of the suction nozzle 12a, the component recognition camera 9 recognizes the component under the first illumination condition, which is different from the first illumination condition. The tip is recognized under the second illumination condition. In other words, the component recognition camera 9 can control the light emission of the illumination unit based on the illumination unit that illuminates the component and the tip of the suction nozzle 12a and the imaging timing.

A board recognition camera 14 positioned on the lower surface side of the X-axis moving table 11 and moving integrally with the mounting head 12 is arranged on the coupling plate to which the mounting head 12 is attached. The substrate recognition camera 14 is arranged on the coupling plate in a posture in which the imaging direction faces downward (Z-axis negative direction side). By moving the mounting head 12 above the board 6 held by the board transfer unit 5, the board recognition camera 14 can take an image of the position recognition mark of the board 6, or move above the board 6 after component mounting. For example, the component mounted on the board 6 is imaged.

By performing image recognition processing on the image data acquired by the component recognition camera 9 and the board recognition camera 14, positional deviation of the component held by the suction nozzle 12a in the mounting head 12 and the positional deviation of the component held by the suction nozzle 12a in the board conveying unit 5 can be detected. Positional deviation of the held substrate 6 can be detected. In the component mounting operation, the mounting head 12 takes these positional deviations into account and corrects the position to mount the component on the board 6 at the mounting position.

Further, as shown in FIG. 3, a carriage 15 having a plurality of tape feeders 8 preliminarily mounted on a feeder base 15a is set in the component supply section 7. As shown in FIG. By clamping the feeder base 15a to the fixed base 4a provided on the base 4 by the clamping mechanism 15b, the position of the carriage 15 is fixed in the component supply unit 7. As shown in FIG. The carriage 15 holds a supply reel 16 that accommodates a carrier tape 17 holding components in a wound state. The carrier tape 17 pulled out from the supply reel 16 is pitch-fed by the tape feeder 8 to a pick-up position 8a by the suction nozzle 12a.

In the component mounting apparatuses M4 and M5 shown in the present embodiment, the trailing portion of the carrier tape 17 (preceding tape) already attached to the tape feeder 8 and the leading portion of the carrier tape 17 (following tape) to be newly attached when the component runs out. A tape splicing method is adopted in which the parts are spliced together by a joint part J using a splicing tape. Therefore, the carrier tape 17 is continuously supplied to the tape feeder 8 without interruption due to replacement of the supply reel 16 .

Then, the mounting head 12 accesses the pick-up position 8a of the tape feeder 8 and picks up the component, whereby the pick-up nozzle 12a picks up the component from the pick-up position 8a. Next, the mounting head 12 that has taken out the component moves above the component recognition camera 9, whereby the component held by the mounting head 12 is imaged by the component recognition camera 9, whereby component recognition is performed.

In the process of executing the component mounting operation described above, there are component setup work for mounting the supply reel 16 on the carriage 15, splicing work for splicing the already mounted leading tape and new trailing tape, and component suction by the mounting head 12. Various operations, such as the adsorption teaching work of checking the operation conditions at the time of picking up and adjusting them as necessary, and the recognition teaching work of checking the recognition conditions of the imaging results of the component recognition camera 9 and making adjustments as needed, are performed by the operator. performed by

Since the degree of difficulty of these works varies depending on the content of the work, workers who perform the work are required to have the skills required according to the work item. For this reason, in the component mounting system 1 shown in the present embodiment, a worker who may be in charge of these work items is targeted, and a worker ID for identifying the worker and an individual work in the execution of each of the above-mentioned work are assigned. The worker data associated with the skill level of each worker is stored, and when allocating the work to the workers, the worker data is referred to and the work is allocated according to the skill level of each worker. That is, since the component mounting system 1 shown in the present embodiment includes the component mounting line 1a configured by connecting a plurality of component mounting apparatuses M4 and M5, the operation of the component mounting line 1a includes: Performed by multiple workers.

Next, the configuration of the control system of the component mounting system 1 will be described with reference to FIG. 4A.

The mechanism drive section 23 is controlled by the device control section 21 to drive the board transfer section 5 , the component supply section 7 and the component mounting mechanism 13 . The device control section 21 refers to the mounting data 22a stored in the storage section 22 and controls each of the above-described mechanical sections, thereby executing component mounting work.

The recognition processing unit 25 performs recognition processing on the results of imaging by the component recognition camera 9 and the board recognition camera 14 .

The communication unit 26 is a communication interface and exchanges signals with other devices and the management device 3a via the communication network 2 .

In addition, sensors for operation confirmation, condition monitoring, etc. are provided at various locations in each mechanical section of the component mounting apparatuses M4 and M5. If any anomaly occurs during operation of the device, these sensors generate a signal corresponding to the condition of the anomaly. When these sensors for operation confirmation are operating normally, they output predetermined signals at the normal timing and sequence set in advance. If there is a disturbance, etc., a signal indicating a sign of abnormality is output.

In addition, regarding the misalignment of the tape feeder 8 in the component supply section 7, the dropping of foreign matter into the mechanism, the clogging of the suction nozzle 12a and the valve, etc., a signal indicating the presence or absence of abnormality is generated by a dedicated sensor provided for each. Send out. Further, the recognition processing unit 25 executes recognition processing according to a predetermined algorithm, and if a correct recognition result cannot be obtained due to a cause such as a defect in the acquired image, the recognition processing unit 25 determines that a recognition error has occurred and issues a notification to that effect. A signal is sent.

The failure occurrence state detection unit 24 detects signals from the sensors for operation confirmation or state monitoring, and information such as the recognition results from the recognition processing unit 25. Detect faulty conditions in work execution. Data on the detected defect occurrence state is stored in the storage unit 22 in chronological order as the work history information 22b. Here, the work history information 22b is information indicating the history (work history) of the work performed by the worker, which is the execution result of the work performed by the worker.

When the operator performs operations, maintenance, etc., on the substrate transport section 5, the component supply section 7, and the component mounting mechanism 13 during operation of the component mounting apparatuses M4 and M5, the operator must A predetermined item is input through the input unit 53 provided on the operator terminal 3c for the purpose. Thereby, the work history for each worker in each of the component mounting apparatuses M4 and M5 is transmitted to the management apparatus 3a.

Next, the management device 3a will be described. The management device 3a is an example of a skill evaluation system.

The management device 3 a includes an overall control section 30 , an evaluation section 32 , a storage section 31 , a worker data update section 35 , an input section 36 , a display section 37 and a communication section 38 .

The overall control unit 30 is a processing arithmetic device, and performs overall management of the component mounting system 1 by controlling the following units based on the programs and data stored in the storage unit 31 .

The evaluation unit 32 evaluates the worker's skill related to the work based on the work history information 22b or 31c and the work evaluation criteria information 31d.

The evaluation unit 32 has a calculation unit 32a that calculates the score of the work. The calculation unit 32a subtracts the score based on error information that is information about an error that may be caused by work.

The storage unit 31 stores production data 31a, worker data 31b, work history information 31c, evaluation criteria information 31d, parts remaining information 31e, production planning information 31f, progress information 31g, and score information 31h.

Here, production data 31a, worker data 31b, work history information 31c, evaluation criteria information 31d, parts remaining information 31e, production plan information 31f, progress information 31g, and score information 31h will be described.

The production data 31a is data that is referred to when each device constituting the component mounting system 1 executes component mounting work.

The worker data 31b is data that associates a worker ID for identifying a worker with the skill level of each worker in executing the work. The worker data 31b defines the skill level of each work (for example, splicing, part setup, suction teaching, and recognition teaching) shown in the work item column for each of a plurality of workers shown in the worker column.

The work history information 31c is history information indicating execution results of work performed by the worker. The work history information 31c includes work history information 22b stored in the component mounting apparatuses M4 and M5 and transmitted via the communication network 2, and based on data transmitted by the worker via the worker terminal 3c. It is created and includes information and the like indicating changes in the failure occurrence state of the equipment operation before and after the work is executed. The work history information 31c is information including the worker, the worker's work content, the execution result of the work content, the work time, the work place, and the like. The work history information 31c summarizes execution results for each worker and each work content.

The evaluation criteria information 31d will be explained using FIGS. 5A to 5E. FIG. 5A is a diagram showing component coefficients for each type of component. FIG. 5B is a diagram showing coefficients of component prices. FIG. 5C is a diagram showing the coefficient of the remaining number of parts. FIG. 5D is a diagram showing a factor of part size. FIG. 5E is a diagram showing coefficients of tape types. FIG. 5F is a diagram showing working time coefficients.

The evaluation criterion information 31d is coefficient information including part coefficient information and time coefficient information.

The component coefficient information is information indicating coefficients defined based on the component information 22c, as shown in FIG. 5A. The parts information 22c is information about parts used in the production apparatus. Specifically, the parts information 22c includes parts prices (parts prices) that are individually set according to the types of parts, the remaining number of parts for each type (parts remaining number), the sizes of parts, and the number of parts that can be accommodated. It contains information about the tape type, etc. Coefficients corresponding to the part price, remaining number of parts, size and tape type are set for each of the part types A to D. FIG.

The evaluation criteria information 31d includes at least one of information about points that are emphasized in skill evaluation and information about points that are not emphasized. The information about the points to be emphasized is information indicating coefficients to be emphasized by the worker. If the coefficient is higher than the reference value of 1.0, it will be weighted. Also. The information about the point of unimportance is the information indicating the coefficient that is not regarded as important or the coefficient that is hardly regarded as important by the worker. If the coefficient is lower than the reference value of 1.0, it is not considered important.

The evaluation criteria information 31d is set based on the parts information 22c. For example, the evaluation criteria information 31d indicates that the higher the part price, the smaller the remaining number of parts, the smaller the size of the part, or the more difficult it is for the operator to handle the container containing the parts (eg, the carrier tape 17). It is set so that the effect on the evaluation of the skill increases as the number increases.

For example, as shown in FIG. 5B, the component prices that are individually set according to the types of the components have coefficients set in advance according to the price level. Specifically, the first price, the second price, and the third price are set so that the higher the price, the higher the coefficient so that the relationship of the first price < the second price < the third price. . For example, if the price is less than the first price, the coefficient is 1.0; if the first price is less than the second price, the coefficient is 1.3; if the second price is less than the third price, the coefficient is 1.7. and the coefficient is set to 2.0 for the third price or higher. This is because if the parts are expensive, it is necessary to work carefully so as not to make mistakes, so the coefficient is set high.

For example, as shown in FIG. 5C, a coefficient is set in advance for the number of remaining parts for each type of part according to the number of remaining parts. Specifically, the first number, the second number, and the third number are in a relationship of the first number<the second number<the third number, and the smaller the number (the remaining number of parts), the higher the coefficient. is set to For example, if the number is less than the first number, the coefficient is 1.5, if the first number or more and less than the second number, the coefficient is 1.2, and if the second number or more and less than the third number, the coefficient is 0.8. and the coefficient is set to 0.5 if the number is equal to or greater than the third number. This is because if a mistake occurs in a part with a small remaining number of parts, the production of the component mounters M4 and M5 may be stopped. The factor is set high because it needs to work.

In addition, the evaluation criteria information 31d may be set so as to change based on the remaining number of parts and the planned number of parts to be received or the number of parts to be used. In other words, the coefficient for the remaining number of parts may be varied based on the relationship between the remaining number of parts, the planned arrival number of parts, the planned use number of parts, and the like.

Also, the evaluation criteria information 31d may be set so as to change according to changes in the remaining number of parts. For example, if the number of parts scheduled to be received and the number of parts scheduled to be used are large and the number of remaining parts is small, the coefficient is changed so that the smaller the remaining number of parts is, the larger the coefficient is. When there are few remaining parts and a large number of remaining parts, the coefficient may be varied so that the larger the remaining number of parts, the smaller the coefficient. In other words, the lower the ratio of the remaining number of parts to the quantity used for production (rarity), the higher the coefficient.

Here, the remaining number of parts is the first remaining number of parts stored in the parts storage 3b, the second remaining number of parts held in the production apparatus, or the sum of the first remaining number and the second remaining number. is. That is, the remaining number of components is the number of inventory in the component storage 3b, the remaining number of components attached to the component mounters M4 and M5 (for example, the remaining number of components of each of the plurality of tape feeders 8), or the sum of these. is. As shown in FIGS. 5A and 5C, the coefficient of the remaining number of parts is set based on the remaining number of parts information 31e, which is the information indicating the remaining number of parts.

For example, as shown in FIG. 5D, a coefficient is set in advance according to the size of the component. Specifically, the first size, the second size, and the third size are set so that the smaller the size, the higher the coefficient so that the relationship of the first size<the second size<the third size is established. . For example, if the size is less than the first size, the coefficient is 1.0; if the size is the first size or more and less than the second size, the coefficient is 0.7; if the size is the second size or more and less than the third size, the coefficient is 0.5. and the coefficient is set to 0.3 for the third size or larger.

Here, the size of a part is the area of the part, the length of one side of the part, the length of the diagonal line of the part, etc. when the part is viewed from above. Also, the size of the component may be based on the body of the component or the external shape of the component including electrodes, depending on the type of the component (chip component, leaded component, etc.).

For example, as shown in FIG. 5E, coefficients are set in advance according to tape types. For example, the coefficient is 1.5 for the first type, 1.2 for the second type, and 0.8 for the third type. The first type, the second type, and the third type are types with different components.

The part coefficients for the part types A to D in FIG. 5A in this embodiment are obtained by multiplying the price, the number of remaining parts, the size and the tape type. Calculation of the component coefficient is merely an example, and is not limited to multiplying the price, remaining number of components, size, and tape type, and may be obtained by addition or weighting. Note that the parts coefficient is not limited to the price, remaining number of parts, size, and tape type.

The time coefficient information, as shown in FIG. 5F, is information indicating a coefficient set for the working time, which is the time required for the worker to perform the work. For example, in the case of splicing work, the work time is the time required from the start to the end of the splicing work. The work hours are individually set according to the type of work.

For example, a working time has a coefficient set in advance according to the length of the working time. Specifically, the first time, the second time, and the third time are set such that the shorter the time, the higher the coefficient so that the relationship of the first time < the second time < the third time. . For example, for a certain task, if the time is less than the first time, the coefficient is 1.5; if the time is between the first time and less than the second time, the coefficient is 1.3; (Coefficient of standard work time) is set to 1.0, and the coefficient is set to 0.6 for the third time or more. As a result, it is possible to prompt the worker to perform the work accurately and quickly.

Note that the coefficient may be set according to the spare time with respect to the scheduled work completion time. For example, a coefficient larger than 1.0 is set as the margin time is longer, the coefficient is set closer to 1.0 as the standard work time is approached, and the coefficient is set to be closer to 1.0 as the margin time is shorter or the work delay time is longer. A smaller coefficient may be set.

In addition, the evaluation criterion information 31d is set such that the more the production progress lags behind the production plan, the greater the influence on the skill evaluation. Note that the evaluation criteria information 31d may include information on production progress.

Also, the evaluation criteria information 31d may be set so as to change according to changes in production progress. In this case, the coefficient may be set according to changes in production progress. Changes in production progress are changes in the progress of production relative to the production plan. For example, the production progress changes as the production progress delays or advances with respect to the production plan.

In addition, the evaluation criterion information 31d is set such that the more the production progress lags behind the production plan, the greater the influence on the skill evaluation. For example, it may be set so that the coefficient of the work related to the product whose production or work is delayed with respect to the production plan is high. This motivates the workers to work accurately and quickly.

In addition, the evaluation criterion information 31d is set such that the more the production progress is ahead of the production plan, the smaller the influence on the skill evaluation. For example, it may be set so that the coefficient of the work related to the product whose production or work is ahead of schedule with respect to the production plan is low. This provides the workers with motivation to work on product types that are delayed in production or work with respect to the production plan.

Also, the evaluation criteria information 31d may be set based on the work information. Here, work information is information about work.

Contains quality information. The evaluation criteria information 31d is set so that the shorter the work time, the longer the spare time, the shorter the overtime after the completion time, or the higher the quality of the work, the greater the effect on skill evaluation. .

Also, the evaluation criteria information 31d is set based on quality information, which is information regarding the quality of the produced article. The evaluation criteria information 31d is set such that the higher the quality of the item, the greater the influence on the skill evaluation. For example, the evaluation criteria information 31d may further include information indicating a quality factor set based on quality information, which is information indicating the quality of the produced article (product). For example, the larger the component mounting positional deviation amount (the difference between the target mounting position and the actual mounting position) output from the visual inspection device provided downstream of the component mounters M4 and M5, the lower the quality factor. , and the quality factor may be set to be higher as the positional deviation amount is smaller. Here, the quality of the product indicated in the quality information may be obtained by evaluating the quality of the product based on an image captured by an imaging device, or may be obtained by evaluating the quality by checking the product by a skilled worker. There may be. Quality information may be included in the evaluation criteria information 31d.

Also, the evaluation criterion information 31d may be set based on facility age information, which is information about the years of use of the component mounting apparatuses M4 and M3. For example, the facility age information is information including the period from when the component mounting apparatuses M4 and M3 were introduced, the period during which the apparatuses were actually operated after the component mounting apparatuses M4 and M3 were introduced, and the like. The evaluation criterion information 31d is set so that the longer the years of use of the component mounting apparatuses M4 and M3 are, the higher the coefficient is set, thereby increasing the influence on the skill evaluation.

Also, the evaluation criterion information 31d may be set based on maintenance information, which is information regarding the remaining time until the next maintenance is performed in the component mounting apparatuses M4 and M3. For example, the maintenance information is information including the remaining time from the current time to the next maintenance execution point. The evaluation criterion information 31d is set such that the shorter the remaining time until the next maintenance is performed on the component mounting apparatuses M4 and M3, the higher the coefficient, thereby increasing the influence on the skill evaluation.

First, as shown in FIG. 6A, the evaluation unit 32 acquires part coefficient information and part remaining number information 31e (S11). Specifically, the evaluation unit 32 acquires the component coefficient information included in the evaluation criterion information 31d from the storage unit 31 . In addition, the evaluation unit 32 receives information indicating the remaining number of components attached to the component mounting apparatuses M4 and M5 transmitted from the component mounting apparatuses M4 and M5 via the communication network 2 and the communication unit 38 and/or communication By acquiring the information indicating the inventory quantity transmitted from the parts storage 3b via the unit 38, the parts remaining quantity information 31e is acquired.

[Operation example 2]
Also, in this operation example, a processing operation for setting the component coefficients after the start of production of the product will be described.

FIG. 6B is a flowchart showing a processing operation for setting component coefficients after starting production of a product in the component mounting system 1 according to the embodiment.

First, as shown in FIG. 6B, the component mounting line 1a of the component mounting system 1 starts production of products (S21).

Next, since the remaining number of parts changes in real time, the overall control section 30 acquires the remaining number of parts information 31e, which is information indicating the remaining number of parts for each type of parts, from the storage section 31 (S22).

Next, the overall control unit 30 reads out the remaining number of parts for each type of parts indicated in the remaining number of parts information 31e stored in the storage unit 31, so that the remaining number of parts for each type of parts is determined. It is determined whether or not the range has been exceeded (S23).

When the overall control unit 30 determines that the remaining number of parts of a specific type exceeds the predetermined range (YES in S23), it changes the part coefficient of the part whose remaining number exceeds the predetermined range (S24). . For example, as shown in FIG. 5C, the overall control unit 30 refers to which part coefficient the remaining number of parts corresponds to, extracts the component coefficient corresponding to the remaining number of parts, and changes the component coefficient to the extracted part coefficient. do.

Next, the overall control unit 30 stores in the storage unit 31 the part coefficients of the parts whose changed remaining number of parts exceeds the predetermined range (S25). Thereby, the part remaining number information 31e of the storage unit 31 is updated.

[Operation example 4]
Also, in this operation example, a processing operation for setting the working time coefficient after the start of production of a product will be described.

FIG. 6D is a flowchart showing a processing operation for setting a working time coefficient after starting production of a product in the component mounting system according to the embodiment.

First, as shown in FIG. 6D, the overall control unit 30 of the management device 3a acquires the production plan information 31f of the storage unit 31 (S41).

Next, the component mounting line 1a of the component mounting system 1 starts production of products (S42).

Next, the overall control unit 30 acquires the progress information 31g from the storage unit 31 (S43).

Next, based on the progress information 31g stored in the storage unit 31, the overall control unit 30 determines whether or not there is a product whose production is delayed (S44).

When the overall control unit 30 determines that there is a product whose production is delayed in a specific product type (YES in S44), the system shown in FIGS. 7A and 7B is shown in FIG. , the working time coefficient for the product whose production is delayed is changed (S45). For example, as shown in FIG. 7B, the overall control unit 30 does not change the coefficient of the work time corresponding to the standard work time, and sets the coefficient of the work time corresponding to the standard work time to be small. , and change it so that the coefficient of a small work time becomes large with respect to the work time corresponding to the standard work time.

Next, the overall control unit 30 stores the changed work time coefficient in the storage unit 31 (S46). As a result, the working time coefficient in the storage unit 31 is updated.

Next, the overall control unit 30 outputs the updated work time coefficient to the display unit 37 (S47). As a result, the updated work time coefficient is displayed on the display unit 37 . In this way, the worker can grasp the working time coefficient for each product type. Then, the overall control unit 30 advances the process to step S48.

Returning to step S44, when the overall control unit 30 determines that the working time coefficient for the specific product type does not exceed the predetermined range (NO in S44), the process proceeds to step S48.

Next, the overall control unit 30 determines whether or not the production of the product has ended (S48).

If the overall control unit 30 determines that the production of the product has ended (YES in S48), it ends the processing operation of FIG. 6D.

On the other hand, when the overall control unit 30 determines that production of the product has not ended (NO in S48), the process returns to step S43.

[Operation Example 5]
In this operation example, a processing operation for calculating a work score will be described.

FIG. 6E is a flowchart showing a processing operation for setting a working time coefficient in the component mounting system according to the embodiment.

First, as shown in FIG. 6E, the evaluation unit 32 acquires the part coefficient information 51a and the time coefficient information included in the work history information 22b and the evaluation criterion information 31d from the storage unit 31 (S51).

Next, the calculation unit 32a of the evaluation unit 32 calculates a work score for each worker (S52).

Here, the work score calculated by the calculator 32a will be described with reference to FIGS. 5A, 7A, and 7B. FIG. 7A is a diagram showing the relationship between working hours and coefficients of working hours. FIG. 7B is a diagram showing work hours, coefficients before change, and coefficients after change.

For example, as shown in FIG. 7A, the work time has a coefficient set in advance according to the length of the work time. FIG. 7A is a specific example of FIG. 5F.

In FIG. 7A, if the work time required for a certain work is less than 90 seconds, the coefficient is 1.5; if it is 90 seconds or more and less than 120 seconds, the coefficient is 1.3; The coefficient (coefficient of standard work time) is set to 1.0, and the coefficient is set to 0.5 if the time is 150 seconds or longer.

When the part is type A in FIG. 5A and the work time required by the worker in FIG. 7A is 100 seconds, the calculator 32a calculates the coefficient as follows.

Coefficient=Parts coefficient 2.016 for part type A in FIG. 5A×Coefficient 1.3 for work time of 100 seconds in FIG. 7A=2.6208

Next, the calculation unit 32a calculates the score of the work based on the numerical value of the work history information. That is, the calculator 32a calculates the score of the work as follows.

Work score = numerical value of work history information x 2.6208 (coefficient)

Also, as shown in FIG. 7B, when the production progress lags behind the production plan, the evaluation criteria information 31d shows that the more the production progress lags behind the production plan, the greater the influence on skill evaluation. may be set as For example, the coefficient for less than 90 seconds is 1.5 to 2.0, and the coefficient for 90 seconds or more and less than 120 seconds is 1.3 to 1.7. is changed to

FIG. 7B exemplifies a case where the coefficient change rate increases as the work time becomes shorter than the standard work time, but the present embodiment is not limited to this. For example, the rate of change of the coefficient may be uniformly increased in the work time shorter than the standard work time.

In addition, in FIG. 7B, the coefficient change rate may be varied according to the work delay time.

In addition, in FIG. 7B, if the production progress is ahead of the production plan, the coefficient may be changed to be smaller.

Next, the evaluation unit 32 outputs the work score calculated for each type of work to the storage unit 31 . Thereby, the storage unit 31 stores the work score for each calculated type (S53).

Next, the overall control unit 30 outputs the work score calculated for each type of work to the display unit 37 . As a result, the work score calculated for each type of work is displayed on the display unit 37 (S54). In this way, the worker can grasp the work score calculated for each type of work. Then, the processing operation of FIG. 6E ends.

Here, a display example of the total score for each worker for a certain period of time will be described with reference to FIGS. 7C and 7D. FIG. 7C is a diagram showing the relationship between workers and total scores. FIG. 7D is a diagram showing total scores for each type of work.

As shown in FIG. 7C, when the calculation unit 32a calculates the total score for each worker, the display unit 37 displays the total score for each worker A1 to A4. For example, when a worker selects one or more of workers A1 to A4 displayed on the display unit 37, the display unit 37 displays the score for each type of work of the selected worker. .

For example, when worker A1 in FIG. 7C is selected, detailed contents of the score of worker A1 are displayed on the display unit 37 as shown in FIG. 7D. The detailed content includes the date and time when the worker A1 worked, the type of work, the type of parts used in the work, the score deduction, the current score, and the like.

Here, score deductions are based on error information regarding errors that may be due to work. For example, in the case of splicing work, errors such as part unmatched due to missing part barcode reading, top tape breakage, number of adsorption errors and recognition errors in tape length 300 mm (total length of test area) before and after splicing There is Recognition errors are, for example, errors that accompany operations such as parts being turned upside down, chips standing up, and parts missing. Further, the target of score deduction may be set to a previously specified error, or a predetermined error among a plurality of types of errors may be deducted. Further, when a predetermined error among a plurality of types of errors is targeted for point deduction, the error to be targeted for point deduction may be freely selected or changed. Further, when a predetermined length of the tape before and after splicing is used as the test area, the number of test areas varies depending on the pitch. Therefore, for example, the greater the pitch, the greater the demerit point per error. For example, if the test area is 300 mm and the pitch of 4 mm = 75 pockets, 30 points are deducted for each error. may This is because the larger the pitch, the larger the number of pockets, so if an error occurs at a large pitch, the effect of the error will be greater.

Here, calculation of the work score will be specifically described with reference to FIG. 7E. FIG. 7E is a diagram showing cases where the gap at the joint between the new tape and the old tape in the splicing work is small and large. As shown in FIG. 7E, when the joint gap is small, the distance between the parts is equal. Therefore, the tape can be sent out smoothly without any error. In addition, when the joint gap is large, the distance between the parts is not uniform at the joint portion, so errors are likely to occur. The evaluation unit 32 provides a score difference or varies a coefficient according to the content of the error such as the size of the gap between the joints and the amount of misalignment of the parts. For this reason, when the joint gap is small, for example, the evaluation unit 32 increases the score of the worker by increasing the coefficient. By deducting the points, the worker's score is evaluated so as to be low.

<Effect>
Next, a skill evaluation system as the component mounting system 1 or the management device 3a, a skill evaluation method used in the component mounting system 1 or the management device 3a, and functions and effects of the program according to the present embodiment will be described.

As described above, the skill evaluation system of the present embodiment includes an information acquisition unit (communication unit 38) that acquires the work history information 22b, which is information indicating the history of work performed by the worker, and the work history information 22b or 31c. and an evaluation unit 32 that evaluates the worker's skill related to the work based on the work evaluation criteria information 31d. The evaluation criteria information 31d includes at least one of information about points that are emphasized in skill evaluation and information about points that are not emphasized.

According to this, based on the work history information 22b or 31c, which is the history of the worker's work, and the evaluation criterion information 31d including the important skills and the non-important skills, the worker's work skills can be evaluated. can be done. Workers are motivated to consider the quality and efficiency of their own work based on the evaluated skills, as it becomes clear which points are emphasized and which are not emphasized in the skill evaluation. do.

Therefore, the skill evaluation system can motivate workers to work.

In particular, conventionally, the evaluation of a worker's skill is mainly determined at intervals of superiors, and is sometimes not objectively determined. In addition, conventionally, since it is only possible to evaluate whether or not an error occurs, there are cases in which it is not possible to appropriately rank the skill of an operator. However, in the present embodiment, the skill of the worker can be evaluated based on the work history information 22b or 31c and the work evaluation criteria information 31d, so the skill of the worker can be determined objectively. . Therefore, since it is possible to appropriately rank the skill of the worker, the worker can work on the work while paying attention to the point that is emphasized in the evaluation of the skill. As a result, workers have a consciousness of making efforts to improve their poor work (skills with low evaluation).

In addition, the skill evaluation method of the present embodiment acquires the work history information 22b, which is information indicating the history of the work performed by the worker, and based on the work history information 22b or 31c and the work evaluation criteria information 31d, A worker's skill regarding work is evaluated, and here, the evaluation criterion information 31d includes at least one of information regarding points to be emphasized in skill evaluation and information regarding points not to be emphasized.

This skill evaluation method also has the same effects as those described above.

Moreover, the program of this Embodiment makes a computer perform a skill evaluation method.

This program also has the same effects as those described above.

Further, in the skill evaluation system of the present embodiment, the evaluation criterion information 31d is set based on the parts information 22c, which is information about parts used in the production equipment.

According to this, it is possible to evaluate the worker's work-related skill based on the part information 22c and the work history information 22b or 31c, so that the worker can be motivated for the work.

Further, in the skill evaluation system of the present embodiment, the part information 22c includes the price of the part (part price), the remaining number of parts (remaining number of parts), the size of the part, or the container (carrier) in which the parts are stored. Contains information about the type of tape 17).

According to this, if the price of the part is high, if the number of remaining parts is small, if the size of the part is small, or if the container is difficult to handle, the operator should carefully perform the work. It can generate motivation to do.

In the skill evaluation system of the present embodiment, the remaining number (remaining number of parts) is the first remaining number of parts stored in the parts storage 3b, the second remaining number of parts held in the production apparatus, Or it is the sum of the first balance and the second balance.

According to this, since it becomes possible to accurately grasp the number of parts remaining, it is possible to more objectively evaluate the worker's work-related skills according to the number of parts remaining.

Moreover, in the skill evaluation system of the present embodiment, the evaluation criterion information 31d is set so as to change according to the change in the remaining number.

According to this, it is possible to more objectively evaluate the worker's work-related skill according to the change in the remaining number of parts.

Also, by increasing the coefficient when the number of remaining parts is small, it is possible to motivate the worker to perform the work carefully.

In addition, in the skill evaluation system of the present embodiment, the evaluation criterion information 31d is set so as to change based on the remaining number (remaining number of parts) and the planned number of parts to be received or the number of parts to be used.

According to this, by using not only the remaining number of parts but also the number of parts to be received or the number of parts to be used, it is possible to determine whether or not the part is highly scarce even if the current number of remaining parts in the production apparatus is small. be able to make better decisions. Therefore, it is possible to more objectively evaluate the worker's work-related skills in accordance with the change in the remaining number of parts.

Further, in the skill evaluation system of the present embodiment, the evaluation criterion information 31d is such that the higher the price of the part, the smaller the remaining number of parts, the smaller the size of the part, or the size of the container containing the parts, It is set so that the more difficult the handling by the worker, the greater the influence on the skill evaluation.

According to this, the higher the price, the smaller the remaining number, the smaller the size, or the more difficult it is for the container operator to handle, for example, by setting the coefficient higher, the effect on the skill evaluation will be greater. Therefore, the worker tries to work on the work with caution for the work that has a large influence on the evaluation of the skill. For this reason, the worker is conscious of trying to prevent the skill evaluation from becoming small for the work that has a large influence on the skill evaluation. As a result, the worker is motivated to perform the work more appropriately, so that it is possible to suppress a decrease in product yield in the component mounting system 1 .

Also, in the skill evaluation system of the present embodiment, the evaluation criterion information 31d is set based on work information, which is information about work.

According to this, the worker's work-related skill can be evaluated based on the work information and the work history information 22b or 31c, so that the worker can be motivated for the work.

In addition, in the skill evaluation system of the present embodiment, the work information includes the work time required for the work, the margin time of the work completion time with respect to the scheduled work completion time, the excess time of the work completion time with respect to the scheduled work completion time, Alternatively, it includes work quality information, which is information about the quality of work.

According to this, it is possible to more objectively evaluate the worker's work-related skills according to the work time, spare time, overtime, or work quality.
