In addition, information may be transmitted and received by email or a communication tool using a data communication line.

Next, the component mounting line L1 will be described in detail with reference to fig. 1. The printing apparatus M1 is a production apparatus having a function of depositing solder on a substrate. The component mounting devices M2 and M3 are production devices having a function of mounting components on a substrate on which solder is deposited. The printing apparatus M1 moves a conveyor belt that supports the substrate from below, and conveys the substrate in the apparatus. The printing apparatus M1 brings a screen mask having pattern openings formed therein into contact with a substrate, supplies solder in a paste form from a solder supply unit onto the screen mask, slides a squeegee on the screen mask, and deposits solder on the surface of the substrate through the pattern openings.

The printing apparatus M1 cleans the screen mask to which the solder is attached by repeating printing, using a disposable cleaning paper and a cleaning agent applied to the cleaning paper to remove the solder attached to the screen mask. The printing apparatus M1 controls motors for operating the respective elements by using a control board (control board), thereby realizing these operations.

The conveyor belt for conveying the substrate, the squeegee (squeegee blade) for depositing solder, the cleaning paper for cleaning the screen mask to which solder is attached, the cleaning agent for removing the solder applied to the cleaning paper and attached to the screen mask, and the filter mounted on the solder supply unit and filtering the supplied solder used in the printing apparatus M1 are replacement parts that are consumed by use and are then consumed and replaced. The control board for controlling the printing apparatus M1 and the motor for operating the elements of the printing apparatus M1 are replacement parts that are replaced when a failure or a malfunction occurs.

Next, the structure of the component mounting devices M2 and M3 will be described with reference to fig. 2. Fig. 2 is a structural explanatory view of a component mounting apparatus of an embodiment of the present disclosure.

The component mounting devices M2 and M3 have the same configuration, and the component mounting device M2 will be described below. In the component mounting apparatus M2, a substrate conveying mechanism 22 is provided on the upper surface of the base 21. The substrate conveying mechanism 22 conveys the substrate B by running a conveyor belt 22a supporting the substrate B from below along the X axis, positions the substrate B, and holds the substrate B. The head moving mechanism 23 provided above the base 21 moves the component mounting head 24 detachably mounted via the plate 23a in the positive and negative directions of the X axis and the Y axis. A nozzle 25 is detachably mounted to a lower end of the component mounting head 24. The nozzle 25 mounted on the component mounting head 24 is held by a clamp claw (not shown).

On the side of the substrate conveying mechanism 22, a plurality of tape feeders 26 are mounted side by side along the X axis on a feeder base 27a of an upper portion of a carriage 27 coupled to the base 21. A plurality of slots for mounting tape feeders 26 are provided in the feeder base 27a, and feeder addresses are set in the respective slots. The carriage 27 is mounted at feeder arrangement positions (positive and negative directions of the Y axis in fig. 2) provided in front and rear of the component mounting device M2. In the component mounting device M2, the mounting position of the tape feeder 26 can be determined by the feeder arrangement position, the feeder address, and the like provided back and forth.

In the carriage 27, a carrier tape 28 for storing the components D supplied to the component mounting device M2 is wound around a reel 29 and held therein. The carrier tape 28 inserted into the tape feeder 26 is fed at regular intervals by a tape feeding mechanism 26a built in the tape feeder 26. Thereby, the components D held by the carrier tape 28 are sequentially supplied to the component supply ports 26b provided at the upper portion of the tape feeder 26.

In the component mounting operation, the component mounting head 24 is moved upward of the tape feeder 26 by the head moving mechanism 23, and vacuum suction and pickup (arrow a) of the component D supplied to the component supply port 26b of the tape feeder 26 are performed by the nozzle 25. The component mounting head 24 holding the component D is moved upward by the head moving mechanism 23 on the substrate B held by the substrate conveying mechanism 22, and the component D is mounted at a predetermined component mounting position Ba on the substrate B (arrow B). Thus, the tape feeder 26 is a component supply device that supplies the component D to the component mounting head 24.

In fig. 2, a substrate camera 30 having an optical axis in a negative direction of the Z axis is mounted on the board 23 a. The substrate camera 30 is moved in the positive and negative directions of the X axis and the positive and negative directions of the Y axis integrally with the component mounting head 24 by the head moving mechanism 23. The substrate camera 30 moves upward of the tape feeder 26 to take a picture of the component D supplied to the component supply port 26b.

The component mounting device M2 includes a control board 32 that controls each part of the component mounting device M2. The recognition processing unit of the control board 32 performs image recognition based on the imaging result of the substrate camera 30, and calculates a supply position offset amount that is offset from the component D supplied from the expected normal supply position. Further, the control board 32 corrects the suction position (stop position of the component mounting head 24) when the nozzle 25 picks up the component D based on the calculated supply position offset amount. In addition, the control board 32 also detects that the component D is not supplied to the component supply port 26b and cannot recognize the supply error of the component D.

In fig. 2, the component mounting head 24 includes a flow sensor 24a that measures the flow rate of air flowing in from the nozzle 25. If the nozzle 25 adsorbs the member D normally, the air flowing in from the nozzle 25 becomes smaller, and the vacuum pressure of the nozzle 25 becomes lower. On the other hand, in the case where the nozzle 25 cannot hold the component D or an adsorption failure occurs in which the component D is adsorbed in an abnormal posture, air flows in from the nozzle 25, and thus the vacuum pressure of the nozzle 25 is not lowered.

The control board 32 detects the presence or absence of occurrence of a suction failure (suction error) based on the measurement result of the flow rate of the air by the flow sensor 24a. Further, a vacuum gauge (pressure gauge) may be provided instead of the flow sensor 24a, and the presence or absence of the occurrence of the suction failure (suction error) may be determined based on the measurement result of the vacuum pressure by the vacuum gauge. Further, the control board 32 measures the flow rate of the air flowing from the nozzle 25 after the component mounting by using the flow rate sensor 24a, thereby detecting a mounting error that the component mounting head 24 receives when the component D cannot be mounted on the substrate B. In addition, a filter (not shown) is provided in the component mounting head 24 to prevent dust and the like sucked by the nozzle 25 from entering a vacuum path of a vacuum pump or the like when the component D is vacuum-sucked. The filter may be provided to the nozzle 25 instead of the component mounting head 24.

In addition, one control board 32 is described for simplicity of description, but the control board 32 may be divided into a plurality of control boards. For example, a control board 32 of the component mounting head 24, a control board 32 of a component camera 31 (described later), a control board 32 of the substrate conveyance mechanism 22, a control board 32 of a tape feeder, and the like are exemplified. Further, the dispersion process for detecting the suction error and the mounting error may be performed by a plurality of control boards 32.

In fig. 2, a component camera 31 having an optical axis directed upward is mounted on the upper surface of the base 21 between the substrate conveying mechanism 22 and the tape feeder 26. When the nozzle 25 having picked up the component D passes above, the component camera 31 photographs the lower surface of the component D held by the nozzle 25 (or the nozzle 25 incapable of holding the component D). The recognition processing unit of the control board 32 performs image recognition based on the imaging result of the component camera 31, and determines whether the posture of the component D held by the nozzle 25 is normal or abnormal, or whether a recognition error occurs in which the component D that should be held by the nozzle 25 cannot be recognized. The component camera 31 may capture a side surface in addition to the lower surface of the component D.

The control board 32 recognizes the image of the imaging results of the substrate cameras 30 and 31, and calculates the suction position shift amount from the desired normal suction position, that is, the normal holding position of the component D held by the nozzle 25 mounted on the component mounting device M2 (working device). When the control board 32 mounts the component D at the component mounting position Ba on the substrate B, the mounting position correction and the mounting posture correction are performed based on the suction position offset amount.

In this way, the conveyor belt 22a for conveying the substrate B, the nozzles 25 for holding the components D, the clamping claws for holding the nozzles 25 in the component mounting heads 24, and the filters provided in the component mounting heads 24 used in the component mounting devices M2 and M3 are replacement parts that are consumed and replaced by use. The control board 32 for controlling the component mounting devices M2 and M3, the motor for operating the components of the component mounting devices M2 and M3, the component mounting head 24 for mounting the nozzle 25, the component supply device (tape feeder 26) for supplying the component D to the component mounting head 24, the board camera 30 for photographing the board B, and the component camera 31 for photographing the component D are replacement parts to be replaced when a failure or a malfunction occurs.

Next, referring to fig. 3, the structure of the part providing system 1 will be described. Fig. 3 is a block diagram showing the structure of a part supply system according to an embodiment of the present disclosure.

The manufacturing information management device 3 installed in the factory F1 of the customer includes a manufacturing information storage unit 41 and a monitoring unit 46. The manufacturing information storage unit 41 is a storage device, and stores installation data 42, a job history 43, a manufacturing plan 44, a maintenance plan 45, and the like. The mounting data 42 is created for each type of mounting substrate manufactured in the component mounting line L1, and includes data such as a speed of operating the squeegee, information for determining the screen mask by a frequency of cleaning the screen mask, a type and size of the component D mounted on the substrate B, a component mounting position Ba (XY coordinates), and a speed of operating the component mounting head 24.

In fig. 3, the monitoring unit 46 sequentially collects the status of the production job, the status of the production apparatus, the result of the maintenance job, and the like from the production apparatus (the printing apparatus M1, the component mounting apparatuses M2, M3) of the component mounting line L1, and stores the collected status, the result of the maintenance job, and the like as the job history 43 in the manufacturing information storage unit 41. Specifically, the monitoring unit 46 associates a job error occurring in the production apparatus with the production apparatus in which the job error occurred, information specifying the relevant parts, the occurrence date and time, and the like, and stores the association as the job history 43.

Examples of the work error include an adsorption error in which the nozzle 25 cannot adsorb the component D, an identification error in which the component D adsorbed and held by the nozzle 25 cannot be identified by the component camera 31, an attachment error in which the component mounting head 24 cannot attach the component D to the substrate B and take back the component D, a supply error in which the component D supplied from the tape feeder 26 (component supply device) cannot be identified by the substrate camera 30, a substrate B jam, dropping, sliding, and conveying error in which the component D cannot be conveyed to a predetermined position.

The monitoring unit 46 also associates an action event occurring in the production apparatus with an occurrence time or the like, and stores the action event as the job history 43. Examples of the operation event include a job stop event in which the production job is temporarily stopped due to a job error or the like, a job restart event in which the production job is restarted after the job is recovered based on an error of the operator, and the like. For example, when a job stop event occurs, information specifying parts such as the tape feeder 26, the component mounting head 24, and the nozzle 25, which cause the job stop, is stored.

The monitoring unit 46 also stores the production log of the production apparatus as the job history 43. As the manufacturing log, correction values used in the component D and the component mounting operation, a flow rate value of the flow sensor 24a at the time of sucking the component, a pressure value of the vacuum gauge at the time of sucking the component, a current value at the time of operating the tape feeder 26, and the like are correlated with information for specifying the relevant parts.

The monitoring unit 46 counts the number of times of use of each part used in the production apparatus according to the operation condition of the production apparatus, and stores the counted number of times as the operation history 43. As the number of uses, there are exemplified the number of times the squeegee (squeegee blade) of the printing apparatus M1 slides on the screen mask, the number of times the screen mask is cleaned by cleaning paper, the number of times the component D is supplied by the tape feeder 26 (the number of components), the number of times the component D is suctioned by the nozzle 25, the number of times the nozzle 25 is attached to or detached from the component mounting head 24, the number of times the nozzle 25 is lifted by the component mounting head 24, the number of times the substrate B is conveyed by the substrate conveying mechanism 22 (the accumulated travel distance of the conveyor belt), and the like.

When the maintenance work of the production apparatus is performed, the monitoring unit 46 associates and stores the adjusted parts, information for specifying the replaced parts, date and time, and the like as the work history 43. Examples of maintenance operations include replacement of a squeegee (squeegee blade) in the printing apparatus M1, replacement of cleaning paper, replenishment and replacement of a cleaning agent, replacement of a filter in the solder supply unit, adjustment of the tape feed mechanism 26a of the tape feeder 26 in the component mounting apparatuses M2 and M3, lifting and lowering of the nozzle 25 of the component mounting head 24, adjustment of the rotation state, replacement of a filter in the component mounting head 24, and the like.

In fig. 3, a manufacturing plan 44 is a manufacturing plan of mounting substrates in the component mounting line L1, which is created by the plan management apparatus 4, and includes the type of mounting substrates to be manufactured, the number of manufacturing pieces, the date and time when the manufacturing is started, the date and time when the manufacturing is ended, and the like. The maintenance schedule 45 is a maintenance schedule of the production apparatus of the component mounting line L1, which is created by the schedule management apparatus 4, and includes a scheduled date and time of maintenance, maintenance contents, and the like.

In fig. 3, the apparatus maintenance support device 5 provided in the support center S includes: the apparatus maintenance storage unit 51, the operation information acquisition unit 58, the part diagnosis unit 59, the inventory information acquisition unit 60, the lead time information acquisition unit 61, and the replacement part management unit 62. The device maintenance storage unit 51 is a storage device that stores operation information 52, maintenance information 53, component replacement timing 54, stock information 55, delivery date information 56, distribution information 57, and the like.

The operation information acquiring unit 58 acquires the job history 43 and the maintenance schedule 45 from the manufacturing information management device 3 installed in the factory F1 of the customer via the external communication network 7. The operation information acquisition unit 58 associates the acquired job history 43 with the information home specifying the plant F1 and stores the operation history as the operation information 52 in the device maintenance storage unit 51.

The operation information acquiring unit 58 associates the acquired maintenance schedule 45 with the information specifying the plant F1, and stores the association in the device maintenance storage unit 51 as the maintenance information 53. That is, the operation information acquiring unit 58 acquires the operation information 52 and the maintenance information 53 of the production apparatuses (the printing apparatus M1 and the component mounting apparatuses M2 and M3) of the customer, respectively. The operation information acquiring unit 58 may acquire the maintenance schedule of the customer from the sales management apparatus 8 of the sales company C1. The operation information acquiring unit 58 may acquire the maintenance schedule directly from the customer by email or the like.

In fig. 3, the component diagnosing unit 59 diagnoses the state of the component including the defective state and the consumed state of the component used in the production apparatus based on the operation information 52, and estimates the component replacement timing for replacing the component with the replacement component for each component based on the state of the component. The component diagnosis unit 59 predicts the failure time of the component based on the state of the component, and estimates the component replacement time for each component based on the predicted failure time of the component.

Specifically, the component diagnosing unit 59 diagnoses the defective state of each component based on the work error, the manufacturing log, and the like included in the operation information 52. For example, the error rate is in a tendency to increase, the error rate is not increased but the correction amount is in a tendency to increase, the deviation (standard deviation) of the correction amount is not larger than the judgment reference, or the like for each predetermined period, and the error state is diagnosed. Here, the judgment standard is a standard value based on a period from the time of distributing the parts to the time of reaching the customer's factory F1 for each part. That is, the component diagnosing unit 59 has a criterion for diagnosing a defective state even before the distribution and the delivery of the components. For example, if the period for distributing and dispensing the parts is set to 20 days of parts, the judgment standard is set to a judgment standard that the parts cannot be used from 20 days of diagnosis or from several days of 20 days later.

The component diagnosing unit 59 estimates the failure state of each component based on the failure occurrence status (number of times, frequency, etc.), using a failure diagnosis model prepared in advance by machine learning. Fig. 4 is a block diagram showing the structure of a component diagnosis unit according to an embodiment of the present disclosure. Specifically, as shown in fig. 4, the component diagnostic unit 59 includes a consumable part diagnostic model 59a, a faulty component diagnostic model 59b, and a pattern comparison unit 59c. The component diagnosing unit 59 uses the consumable part diagnosing model 59a or the faulty component diagnosing model 59b to estimate the level of failure of the component from the obtained error occurrence situation, and thereby diagnoses the failure state or the consumable state of at least one component. The consumable part diagnostic model 59a and the faulty part diagnostic model 59b are models that can indicate whether or not the parts provided in the production apparatus are in a normal state.

The consumable part diagnostic model 59a and the faulty part diagnostic model 59b are created by learning using the error occurrence situation that is a recommended standard for the manufacturer of the manufacturing apparatus. The pattern comparison unit 59c estimates the failure state of the diagnosed component based on the number of times and frequency included in the error occurrence situation of the production apparatus to be compared, which is the generated learning model, that is, the consumable part diagnosis model 59a or the failed part diagnosis model 59b, and whether or not the frequency exceeds a predetermined value (judgment criterion).

The component diagnosing unit 59 diagnoses the wear state of each component based on the number of times of use of each component included in the operation information 52, replacement information of the component during maintenance, and the like. For example, the amount of use (margin) of the cleaning paper is diagnosed from the accumulated number of times of execution of cleaning of the screen mask. The wear state of the nozzle 25 and the filter is diagnosed based on the results of the cumulative number of suctions of the nozzle 25, the cumulative use time of the filter, and the like, and the life (criterion of the number of times, time, and the like) determined in advance for each component.

The component diagnostic unit 59 predicts the failure time of the component based on the operation error, the operation event, the number of times of use of each component, and the like included in the operation information 52. For example, the failure time is predicted based on the correlation between the failure rate (judgment reference) and the number of times the component of the tape feeder 26 is supplied, the number of times and frequency of occurrence of the recognition error, the fluctuation of the current value when the tape feeding mechanism 26a of the tape feeder 26 is operated, and the like. The component diagnosing unit 59 may diagnose the component by one judgment standard or may diagnose the component by a plurality of judgment standards.

The component diagnosis unit 59 determines a component to be replaced before the production of the mounting board in the factory F1 by the customer is hindered, based on the diagnosed state of the component and the predicted failure time of the component, and estimates a component replacement time when the component is to be replaced with a new replacement component. The component diagnosis unit 59 associates the estimated component replacement time with information specifying the customer and the component, and stores the information in the device maintenance storage unit 51 as the component replacement time 54. The estimation of the component replacement time here refers to the estimation of the component replacement time from the time when the components are distributed to the time when the components reach the customer's factory F1.

In fig. 3, the stock information acquiring unit 60 acquires stock information of replacement parts stored in the parts storage 6 provided in the support center S. The stock information acquiring unit 60 acquires stock information of the replacement parts stored in the parts storage 9 of the sales company C1 from the sales management device 8 provided in the sales company C1 via the external communication network 10. The stock information acquiring unit 60 acquires stock information of the replacement parts stored in the parts storage 13 of the parts manufacturing company W1 from the parts manufacturing management device 12 provided in the parts manufacturing company W1 via the external communication network 10. The stock information acquiring unit 60 associates the acquired stock information with the position of the replacement part, and stores the associated stock information as stock information 55 in the device maintenance storage unit 51.

The delivery date information acquiring unit 61 acquires delivery date information until the replacement parts stored in the parts storage 6 of the support center S are delivered to the factory F1 of the customer. The delivery date information acquiring unit 61 acquires, from the sales management device 8 of the sales company C1, delivery date information from the time when the replacement parts stored in the parts storage 9 of the sales company C1 are delivered to the factory F1 of the customer. The delivery date information acquiring unit 61 acquires, from the component manufacturing management device 12 of the component manufacturing company W1, delivery date information from the time when the replacement component stored in the component storage 13 of the sales company C1 is delivered to the customer's factory F1.

In addition, when the component manufacturing company W1 does not have an inventory of replacement components, the delivery date information acquiring unit 61 acquires delivery date information from the component manufacturing company W1 to the factory F1 where replacement components are manufactured or from the time when replacement components during manufacturing are completed and delivered to the customer. The delivery date information acquiring unit 61 associates the acquired delivery date information with the location of the replacement part or the factory F1 of the customer to be delivered, and stores the associated delivery date information in the device maintenance storage unit 51 as delivery date information 56.

In fig. 3, the replacement parts management unit 62 distributes replacement parts to the factory F1 that delivers customers based on the parts replacement time 54, the stock information 55, the delivery date information 56, and the maintenance information 53. Specifically, when the replacement part of the part replacement time 54 is estimated by the part diagnosis unit 59, the replacement part management unit 62 determines the location (support center S, sales company C1, part manufacturing company W1, etc.), the route to deliver the replacement part to the customer, the delivery date and time of the replacement part, and the delivery date and time of the delivery. That is, the replacement part management unit 62 identifies the source (location), route, and date of delivery of the replacement part so that the replacement part of a predetermined number of days (for example, 3 days) or less is delivered to the customer until the time of replacement of the part, and stores the replacement part in the device maintenance storage unit 51 as the assignment information 57.

The replacement part management unit 62 transmits (distributes) the specified allocation information 57 to the transmission source of the replacement part. For example, when the transmission source is the sales company C1, the replacement part management unit 62 transmits the allocation information 57 to the sales management apparatus 8 of the sales company C1 via the external communication network 10. When the transmission source is the component manufacturing company W1, the replacement component management unit 62 transmits the allocation information 57 to the component manufacturing management device 12 of the component manufacturing company W1 via the external communication network 10.

Here, an example of a route for delivering the replacement parts specified by the replacement part management unit 62 to the customer will be described with reference to fig. 5A and 5B. Fig. 5A and 5B are diagrams showing examples of delivery routes of replacement parts according to an embodiment of the present disclosure. Fig. 5A shows an example in which the replacement parts are directly delivered from the parts manufacturing companies W1, W2 that manufacture the replacement parts to the factories F1, F2, F3 (customers). For example, in the case of a replacement part that can be replaced by a customer's operator in the factory F1, such as a scraper, cleaning paper, cleaning agent, conveyor belt 22a, nozzle 25, filter, or the like, the replacement part management unit 62 determines a route so that the replacement part is directly delivered to the factory F1 from the part manufacturing companies W1, W2 that manufacture the replacement part.

In addition, when the parts manufacturing companies W1, W2 are not in stock, there is no margin up to the parts replacement time 54, and when the support center S or the sales company C1 is in stock, the replacement parts management section 62 determines a route so that the replacement parts are delivered directly from the support center S or the sales company C1 to the factory F1. In addition, in the case of replacement parts that can be replaced by the operators of customers in the factory F1 such as the component mounting head 24 and the tape feeder 26, or in the case where the stock for borrowing exists in the support center S or the sales company C1, the replacement parts management section 62 determines a route so that the replacement parts are directly delivered (borrowed) from the support center S or the sales company C1 to the factory F1. The term "there is no margin until the component replacement time 54" here means that the delivery date is equal to or later than the component replacement time 54 based on the delivery date information acquired by the delivery date information acquiring unit 61.

Fig. 5B shows an example in which the replacement parts are delivered from the parts manufacturing companies W1, W2 or the support center S to the sales company C1, and then delivered from the sales company C1 to the factories F1, F2, F3 (customers). For example, in the case of replacement parts such as the control board 32, the motor, the clamp claw, the board camera 30, and the component camera 31, which are replaced by service engineers of the sales company C1 in the factory F1, the replacement parts management unit 62 determines a route so that the replacement parts are temporarily delivered to the sales company C1 serving as the customer and then delivered to the factory F1.

At this time, the replacement part management unit 62 performs distribution so that the service engineer of the sales company C1 holds the replacement part and delivers it, based on the maintenance information 53, in combination with the maintenance date and time of the factory F1. That is, the route to the customer (factory F1) includes an organization (sales company C1) to which a service engineer who performs trimming of the production facility of the customer belongs. The organization that performs the trimming of the customer' S production facility is not limited to the sales company C1, and may be a maintenance-dedicated company or a support center S.

In this way, the replacement part management unit 62 issues the distribution information 57 including the replacement parts to the delivery route of the customer based on the replacement mode such as whether the customer has replaced the replacement parts or not, in addition to the replacement part replacement time 54, the maintenance information 53, the inventory information 55, and the delivery date information 56.

In addition, when there is a replacement part that is scheduled to be produced, and is scheduled to be manufactured by the part manufacturing companies W1, W2 without stock, and the delivery date of the factory F1 that delivers to the customer becomes long, the part diagnostic unit 59 estimates the part replacement time so that the replacement part can be distributed as early as possible. That is, when the replacement part management unit 62 determines the allocation information, the part diagnosis unit 59 may change the estimated part replacement time for each replacement part based on the inventory information 55 and the delivery date information 56 so that the delivery of the replacement part catches up with the replacement at the customer.

As described above, the apparatus maintenance support device 5 includes: an operation information acquiring unit 58 that acquires operation information 52 of the production apparatuses (printing apparatus M1, component mounting apparatuses M2, M3) of the customer (F1), respectively; a component diagnosis unit 59 for diagnosing the state of a component used in the production apparatus based on the operation information 52, and estimating a component replacement time 54 when the component is replaced with a replacement component based on the state of the component; and a replacement parts management unit 62 for distributing replacement parts based on the parts replacement time 54. This can appropriately assist in maintenance of the production apparatus.

Next, a device maintenance method (device maintenance program) for replacing parts used in the production device of the distribution customer will be described along the flowchart of fig. 6. Fig. 6 is a flow chart of a device maintenance method of an embodiment of the present disclosure. In fig. 6, reference symbol ST denotes a process. First, the operation information acquisition unit 58 acquires the operation information 52 of the production apparatus from the factory F1 of the customer (ST 1: operation information acquisition step). Next, the component diagnosing unit 59 diagnoses the state of the component including the defective state and the worn state of the component used in the production apparatus based on the operation information 52 (ST 2: component diagnosing step). Next, the component diagnosis unit 59 determines whether or not there is a component to be replaced based on the state of the component (ST 3: component replacement determination step).

If there is no component to be replaced (no in ST 3), the process returns to the operation information acquisition step (ST 1) to diagnose the state of the component of the factory of the other customer. The diagnosis of the state of the parts in each factory (customer) is performed at predetermined intervals (for example, at each type of mounting board, daily basis, zhou Shanwei).

In FIG. 6, when there is a component to be replaced (YES in ST 3), the component diagnosis unit 59 estimates a component replacement time 54 when the component is replaced with a replacement component based on the state of the component (ST 4: component replacement time estimation step). Alternatively, the component diagnosis unit 59 predicts the failure time of the component based on the state of the component, and estimates the component replacement time 54 based on the predicted failure time of the component.

The stock information acquiring unit 60 acquires stock information 55 of the replacement parts at the support center S, the sales company C1, and the parts manufacturing companies W1 and W2 (ST 5: stock information acquiring step). Next, the delivery date information acquiring unit 61 acquires the delivery date information 56 of the replacement parts at the support center S, the sales company C1, and the parts manufacturing companies W1 and W2 (ST 6: delivery date information acquiring step). Next, the operation information acquisition unit 58 acquires the maintenance information 53 of the customer (factory F1) who replaces the parts (ST 7: maintenance information acquisition step).

In FIG. 6, the replacement part management unit 62 determines a route for delivering the replacement part to the customer based on the part replacement time 54, the stock information 55, the delivery date information 56, and the maintenance information 53 (ST 8: delivery route determination step). Next, the replacement part management unit 62 creates replacement part allocation information 57 including the source of delivery, route, date and time of delivery, and date and time of delivery of the replacement part based on the part replacement time 54, and transmits (distributes) the replacement part allocation information 57 to the source of delivery of the replacement part (including the passing position of the replacement part) (ST 9: replacement part allocation step).

In the replacement part distribution step (ST 9), the notification of maintenance of the replacement part distribution information 57 to the factory F1 (customer) may be performed, or the replacement part may be sent to the factory F1 (customer) or the dispatch of a service engineer performing maintenance or repair of the production apparatus may be performed based on the replacement part distribution information 57. The transmission method of the replacement part allocation information 57 is set by a service contract of the customer.

By diagnosing the state of the component based on the operation information 52 of the production apparatus of the customer, estimating the component replacement timing 54 and distributing the replaced component, it is possible to replace the component before the occurrence of the component due to a defect that prevents production in the production apparatus of the customer, and properly assist in the maintenance of the production apparatus.

The present disclosure has been described above based on the embodiments. Those skilled in the art will appreciate that variations to this embodiment are also within the scope of the disclosure. In the delivery route determination step (ST 8), the route for delivering the replacement part to the customer is determined using the maintenance information 53, but the route for delivering the replacement part to the customer may be determined without using the maintenance information 53. That is, ST7 in the flow described in fig. 6 may be omitted.

The "period from the time of distributing the parts to the time of reaching the factory F1 of the customer" may be a predetermined period, or even one part, a distribution period may be set, or a plurality of periods may be set by an enterprise that processes the materials constituting the parts. Further, an optimal period from the time of distributing the parts to the time of reaching the customer's factory F1 may be set for each part by using machine learning and an optimal algorithm. In this way, more accurate part distribution can be performed.

The component diagnosis unit 59 may estimate the replacement timing of the component based on the stock information 55 of the replacement component at the support center S, the sales company C1, and the component manufacturing companies W1 and W2 acquired by the stock information acquisition unit 60. In this case, the inventory information acquiring step of ST5 in the flowchart described in fig. 6 is performed before the component replacement timing estimating step of ST 4. In this way, more accurate part distribution can be performed.

Further, the above-described judgment criteria may make it difficult to diagnose the defective state. In this case, the component may be diagnosed as defective when a predetermined time or a predetermined number of times has elapsed from the time of use of the component. In order to improve the accuracy of the judgment, whether the value of the predetermined time or the predetermined number of times of use is appropriate or not is considered to be appropriate or not is distribution of replacement parts or not. In order to improve the accuracy of the judgment, a predetermined time and a predetermined number of uses suitable for the customer can be set by using a technique such as machine learning or predetermined weighting.

In the above description, the printing apparatus and the component mounting apparatus are described as production apparatuses, but other production apparatuses may be used. For example, the production apparatus may be a plasma processing apparatus such as a plasma cleaning apparatus or a plasma etching apparatus, or a semiconductor manufacturing apparatus used in a process of manufacturing a semiconductor such as a die bonder. In the case where the production apparatus is a plasma processing apparatus or a semiconductor manufacturing apparatus, examples of the replacement component include at least one of an operating mechanism, a glass window member, and a substrate supporting member used for operating a control board, a camera, a motor, a conveyor, and a semiconductor.
