Description

Technical Field

[0001] The present disclosure relates to component mounting systems. Background Art

[0002] In the past, there is known a component mounting system described in Japanese Patent Publication No. 2014-183164 (hereinafter referred to as Patent Document 1). The component mounting system includes a component mounting device and a nozzle inspection device for inspecting the nozzles used in the component mounting device. The nozzle inspection device inspects the nozzles that have been cleaned by the nozzle cleaning device. The nozzle inspection device determines whether the nozzle is in an unsuitable state based on an image obtained by photographing the nozzle. The nozzle that is determined to be in an unsuitable state is removed from the nozzle holder as an NG (unsuitable) nozzle. Then, a nozzle that is not in an unsuitable state, that is, an OK (suitable) nozzle, is added to the nozzle holder. Therefore, when the nozzle holder is moved to the component mounting device, it is possible to prevent the nozzle that is in an unsuitable state from being mistakenly used in the component mounting device.

[0045] [Details of the embodiments of the present disclosure]

[0046] The following is a description of the embodiments of the present disclosure. In addition, the present disclosure is not limited to these examples, but is shown by the scope of the claims, and is intended to include all changes within the meaning and scope equivalent to the scope of the claims. In the following description, sometimes only part of the same components are marked with numbers, and the numbers of other components are omitted.

[0047] <Component Mounting System>

[0048] Below, refer to Figures 1 to 11The embodiments of the present disclosure are described. Figure 1 As shown, the component mounting system 10 of the present embodiment includes a first component mounting device 30A and a second component mounting device 30B (an example of at least one component mounting device), a nozzle cleaning device 20 and a server 11 (an example of a management device). These devices are connected in a manner that can communicate with each other, such as via the Internet. The first component mounting device 30A and the second component mounting device 30B are devices that use a nozzle 50 to mount components P on a substrate B. The nozzle cleaning device 20 is a device that cleans the nozzle 50 used in the first component mounting device 30A and the second component mounting device 30B and inspects the nozzle 50.

[0049] <Component mounting device>

[0050] The first component mounting device 30A and the second component mounting device 30B are configured in the same manner, and therefore, hereinafter, unless otherwise specified, the first component mounting device 30A and the second component mounting device 30B are not distinguished and are simply referred to as "component mounting devices 30". Figure 2 As shown, the component mounting device 30 includes a base 31 , a transport conveyor 32 , a component supply section 34 , a head unit 36 ​​, a driving section 38 , and a nozzle replacement device 60 .

[0051] The transport conveyor 32 is arranged at the center of the base 31 ( Figure 2 The transport conveyor 32 includes a pair of transport belts 33 that are driven in a circular manner in the left and right directions, and the substrate B on the transport belts 33 is transported to the right by friction with the transport belts 33. In this embodiment, the substrate B is transported from the left side into the component mounting device 30 by the transport conveyor 32. The transported substrate B is transported to the working position in the center of the base 31 by the transport conveyor 32 and stops there.

[0052] Component supply units 34 are provided at four locations on the base 31 so as to surround the periphery of the work position. In each component supply unit 34, a large number of feeders 35 for supplying components P are provided adjacent to each other in the left-right direction.

[0053] At the working position, the component P is supplied by the feeder 35 and mounted on the substrate B by the mounting head 37 of the head unit 36. Then, the substrate B with the component P mounted thereon is transported to the right by the transport conveyor 32 and carried out to the outside of the component mounting device 30.

[0054] The driving unit 38 moves the head unit 36 ​​in the X-axis direction and the Y-axis direction within a predetermined movable range. As the driving unit 38, a two-axis or three-axis ball screw mechanism using a motor as a driving source can be exemplified.

[0055] The head unit 36 ​​is provided with a plurality of mounting heads 37. Each mounting head 37 can be independently raised and lowered relative to the head unit 36 ​​by a Z-axis motor (not shown).

[0056] The mounting head 37 includes a nozzle shaft extending in the vertical direction and a nozzle 50 (see FIG. 1 ) mounted on the front end (lower end) of the nozzle shaft. Figure 4 ). Negative pressure is supplied to the mounting head 37 from an air supply device (not shown), thereby generating suction force at the front end of the suction nozzle 50. Thus, the suction nozzle 50 can adsorb the component P. When the suction nozzle 50 adsorbing the component P moves to the mounting position of the substrate B, positive pressure is supplied from an air supply device (not shown), thereby releasing the suction at the front end of the suction nozzle 50. Thus, the suction nozzle 50 can mount the component P.

[0057] <Nozzle>

[0058] like Figure 4 As shown, the suction nozzle 50 includes: a base 51; a suction portion 52 extending downward from the base 51; and a flange portion 53 expanding outward from the outer periphery of the base 51. The base 51 is a portion mounted on the front end of the suction nozzle shaft. The base 51 is provided with a mounting hole 54 for accommodating the front end of the suction nozzle shaft. The suction portion 52 sucks and holds the component P at the lower end. Figure 6 As shown, a through hole 55 is provided extending vertically from the adsorption portion 52 to the lower portion of the base 51. The through hole 55 communicates with the mounting hole 54. The diameter of the through hole 55 is smaller than that of the mounting hole 54.

[0059] like Figure 4 As shown, an identification mark 56 recording identification information of the suction nozzle 50 is provided on the upper surface of the base 51. Although the details will be described later, the suction nozzle information as various information related to the suction nozzle 50 is associated (corresponding) with the identification information of the suction nozzle 50 and stored in the server 11. It should be noted that the identification mark 56 of the suction nozzle 50 can also be provided on the upper surface of the flange portion 53, for example.

[0060] <Nozzle Holder>

[0061] like Figure 2 and Figure 3 As shown, the component mounting device 30 includes a nozzle holder 61 that can be attached and detached from the base 31. The nozzle holder 61 is arranged on the base 31 within the movable range of the head unit 36. The nozzle holder 61 is a tray-shaped member. The nozzle holder 61 can accommodate a plurality of nozzles 50 (see Figure 5). Although not described in detail, the nozzle holder 61 is a part of the nozzle replacement device 60 provided on the base 31 of the component mounting device 30. The nozzle replacement device 60 is a well-known device for removing the nozzle 50 mounted on the nozzle shaft and installing the nozzle 50 accommodated in the nozzle holder 61 to the nozzle shaft.

[0062] like Figure 5 As shown, the nozzle holder 61 includes: a fixed portion 62; a movable portion 63, which can slide in the left-right direction (X-axis direction) relative to the fixed portion 62; and a supporting portion 64, which supports the movable portion 63 relative to the fixed portion 62. A plurality of retaining holes 65 are formed in the fixed portion 62, which penetrate in the up-down direction. The retaining hole 65 is a stepped hole having a stepped surface 66 at the edge of the hole. Four long holes 67 are formed in the movable portion 63, which penetrate in the up-down direction and extend in the sliding direction of the movable portion 63. The movable portion 63 is arranged above the fixed portion 62, and each long hole 67 is connected to the plurality of retaining holes 65. At the edge of the hole of the long hole 67, a plurality of protrusions 68 are provided to extend in a direction orthogonal to the sliding direction of the movable portion 63 (front-back direction, Y-axis direction).

[0063] The movable portion 63 is disposed at the first position ( Figure 5 The movable portion 63 is in the second position, and the protrusion 68 is arranged between the holding hole 65 and the second position (not shown) between the holding hole 65, and slides in the left-right direction relative to the fixed portion 62. When the movable portion 63 is in the second position, the protrusion 68 is arranged between the holding holes 65, and the step surface 66 is exposed upward. As a result, the suction nozzle 50 can be accommodated in the holding hole 65. When the movable portion 63 is in the first position, as shown in FIG. Figure 6 As shown, the protrusion 68 is arranged above the flange 53, and the flange 53 is sandwiched between the step surface 66 of the fixing portion 62 and the protrusion 68. Thus, the suction nozzle 50 is held by the nozzle holder 61.

[0064] like Figure 5 As shown, the nozzle holder 61 has an identification mark 69 on the upper surface of the support portion 64, which records the identification information of the nozzle holder 61. Although the details will be described later, the nozzle information of the nozzle 50 held by the nozzle holder 61 is stored in the server 11 in association with the identification information of the nozzle holder 61 and the holding position of the nozzle 50 held in the nozzle holder 61.

[0065] The component mounting device 30 has a first camera 40, a second camera 41 and a third camera 42. Figure 3As shown, the first camera 40 is fixed to the head unit 36 ​​in a state where the imaging surface faces downward. The first camera 40 is configured to image a reference mark (not shown) of the substrate B to identify the position and posture of the substrate B. In addition, the first camera 40 is configured to be able to image the nozzle holder 61 and the nozzle 50 accommodated in the nozzle holder 61 from above.

[0066] like Figure 2 As shown, the second camera 41 is arranged with its imaging surface facing upward on the base 31. The second camera 41 images the component P held by the suction nozzle 50 from below.

[0067] like Figure 3 As shown, the third camera 42 is attached to the support member 39 that supports the head unit 36. The third camera 42 is a so-called side view camera, and captures an image of the component P held by the suction nozzle 50 from the side.

[0068] The adsorption state of the component P relative to the suction nozzle 50 can be detected based on the images of the second camera 41 and the third camera 42. For example, by detecting the displacement of the adsorption position and the displacement of the adsorption angle, the position and angle of the component P relative to the substrate B can be corrected, thereby improving the mounting accuracy of the component P. In addition, based on the images of the second camera 41 and the third camera 42, information related to the appearance of the suction nozzle 50, such as whether the front end of the suction nozzle 50 is defective, can be obtained.

[0069] like Figure 1 As shown, the component mounting device 30 includes a control unit 43. The control unit 43 is connected to each device such as the transport conveyor 32, the head unit 36, the drive unit 38, the first camera 40, the second camera 41, and the third camera 42. In addition, the control unit 43 stores a mounting program for executing the mounting operation on the substrate B, a transport program for transporting the substrate B, and a photographing program for each camera to photograph a photographing object.

[0070] The control unit 43 controls the transport conveyor 32 and the head unit 36 ​​according to the transport program and the installation program, so that the transport conveyor 32 transports the substrate B to the working position in the center of the base 31, and the head unit 36 ​​performs the mounting operation of mounting the component P on the substrate B.

[0071] In addition, the server 11 is connected to the control unit 43 in a communicable manner. The control unit 43 can receive information about the substrate B to be produced, information about the components P to be mounted on the substrate B, and information about the production plan from the server 11. It should be noted that in the present embodiment, the so-called "production" means mounting components P on the substrate B carried onto the base 31 in the component mounting device 30.

[0072] <Nozzle cleaning device>

[0073] The nozzle cleaning device 20 includes a setting unit 21, an imaging unit 22, a cleaning unit 23, an inspection unit 24, and a control unit 25. The setting unit 21 is a portion where the nozzle 50 is set in the nozzle cleaning device 20. In the present embodiment, the setting unit 21 is provided with a nozzle holder 61.

[0074] The photographing unit 22 is configured to photograph the nozzle holder 61 and the nozzle 50 accommodated in the nozzle holder 61 from above. In the cleaning unit 23, the nozzle 50 is cleaned according to the cleaning procedure. Although not described in detail, the cleaning unit 23 can remove only the necessary nozzles 50 from the plurality of nozzles 50 held by the nozzle holder 61 provided in the installation unit 21 for cleaning. In the inspection unit 24, the nozzle 50 is inspected according to the inspection procedure to see whether it is suitable for production.

[0075] When foreign matter adheres to the through hole 55 of the suction nozzle 50 (see Figure 6 ) and the suction nozzle 50 is clogged, the air supply device reduces the suction force generated by the front end of the suction portion 52. As a result, there is a situation where the component P cannot be held by the mounting head 37. Therefore, when inspecting the suction nozzle 50, check whether the suction nozzle 50 is clogged. For example, from the bottom ( Figure 6 The size (area) of the through hole 55 in the obtained image is investigated by taking a camera shot. The clogging of the suction nozzle 50 can be checked by measuring the flow rate of the air passing through the suction nozzle 50.

[0076] Furthermore, in the inspection of the suction nozzle 50 , in addition to the inspection of clogging of the suction nozzle 50 , an inspection related to the appearance of the suction nozzle 50 , such as whether the tip portion of the suction nozzle 50 is damaged, may be performed.

[0077] The control unit 25 of the nozzle cleaning device 20 is communicatively connected to the server 11. The control unit 25 can receive and store the cleaning program, the inspection program, etc. from the server 11. The control unit 25 controls the imaging unit 22, the cleaning unit 23, the inspection unit 24, etc. to execute various programs.

[0078] <Server>

[0079] The server 11 stores various programs used in the various devices of the component mounting system 10, information on the production plan, information related to the substrate B and the component P, identification information of the suction nozzle 50, suction nozzle information, identification information of the suction nozzle holder 61, etc. The server 11 may also include a control unit 12 for controlling the various devices of the component mounting system 10.

[0080] <Storage of Information Related to Nozzle Holders in Component Mounting Devices to Server>

[0081] In this embodiment, the control unit 43 of each component mounting device 30 stores the identification information of the nozzle holder 61 and the information of the holding position of the nozzle 50 in the nozzle holder 61 in association with the identification information of each nozzle 50 in the server 11 at a predetermined timing. Here, the so-called predetermined timing includes, for example, the timing when the nozzle holder 61 is moved from the nozzle cleaning device 20 to the component mounting device 30, when production is completed, and the timing indicated by the operator. The following describes the specific process of storing the information related to the nozzle holder 61 in the component mounting device 30 to the server 11.

[0082] The control unit 43 of the component mounting device 30 causes the first camera 40 to photograph the identification mark 69 of the nozzle holder 61 and the identification mark 56 of the nozzle 50. The control unit 43 performs image processing on the photographed image to obtain the identification information of the nozzle holder 61, the identification information of each nozzle 50, and the information of the holding position of each nozzle 50. The control unit 43 stores the identification information of the nozzle holder 61 and the information of the holding position of each nozzle 50 in the server 11 in association with the identification information of each nozzle 50. It should be noted that the information of the holding position of the nozzle 50 can be set, for example, as coordinates corresponding to each holding position (the position of the holding hole 65) when the nozzle holder 61 is held in each device.

[0083] According to the above-mentioned structure, the nozzle information of the nozzle 50 held at the holding position can be obtained based on the identification information of the nozzle holder 61 and the holding position of the nozzle 50. Specifically, the component mounting device 30 and the nozzle cleaning device 20 obtain the identification information of the nozzle holder 61 by photographing the identification mark 69 of the nozzle holder 61, thereby being able to obtain the nozzle information of the multiple nozzles 50 held by the nozzle holder 61 and the holding position at which each nozzle 50 is held. Therefore, according to the above-mentioned structure, compared with the case where the identification information of each nozzle 50 is obtained by photographing the identification marks 56 of the multiple nozzles 50, the nozzle information of each nozzle 50 can be obtained in a short time.

[0084] <Storage of Usage Information in Component Mounting Device to Server>

[0085] In the present embodiment, the component mounting device 30 stores usage information, which is information related to the usage state of the suction nozzle 50, in the server 11. The usage information is included in the suction nozzle information. Figure 7 , the process of saving the usage information in the component mounting device 30 to the server 11 is explained.

[0086] Before starting production, the control unit 43 of the component mounting device 30 determines whether the nozzle 50 can be used based on the production plan and nozzle information, etc. (details will be described later). The control unit 43 controls the nozzle replacement device 60 to install the nozzle 50 suitable for production on the nozzle shaft. It should be noted that when the nozzle 50 installed on the nozzle shaft during the last production is directly used, the nozzle 50 is not replaced. The control unit 43 stores the identification information of the nozzle 50 used for production installed on each mounting head 37 (S10).

[0087] Production is started using the component mounting device 30 (S11). During production, the control unit 43 stores the usage information of each suction nozzle 50 (S12). Specifically, the control unit 43 stores the number of times each suction nozzle 50 is used during production. Regarding the number of uses, the process from the suction nozzle 50 adsorbing the component P and mounting the adsorbed component P on the substrate B is counted as one. The number of uses is accumulated from the last cleaning of the suction nozzle 50. When the information that the cleaning of the suction nozzle 50 has been completed is saved to the server 11, the number of uses is reset to 0. The resetting of the number of uses is performed, for example, by the control unit 12 of the server 11. In addition, the control unit 43 stores adsorption error information as information related to the adsorption error of each suction nozzle 50. The adsorption error information is, for example, the number of occurrences of adsorption errors.

[0088] During production, in order to confirm the suction state of the suction nozzle 50 on the component P, the second camera 41 and the third camera 42 are used to take pictures. The control unit 43 can also obtain information related to the appearance of the suction nozzle 50 (appearance information) by performing image processing on these photographed images and store them. The appearance information of the suction nozzle 50 includes, for example, whether the front end of the suction nozzle 50 is defective, whether foreign matter is attached to the outer surface of the suction nozzle 50 or the inner wall of the through hole 55, and other information.

[0089] The usage information of the suction nozzle 50 includes at least one of the usage count of the suction nozzle 50, adsorption error information, and appearance information. The usage information of the suction nozzle 50 of the present embodiment includes the usage count of the suction nozzle 50, adsorption error information, and appearance information. The control unit 43 stores the usage information of each suction nozzle 50 in the server 11 (S13) at a predetermined timing in association with the identification information of the suction nozzle 50. The so-called predetermined timing includes, for example, the completion of production, regular timing during production, the timing when the suction nozzle 50 as the object is detached from the nozzle shaft and returned to the nozzle holder 61, the timing indicated by the operator, and the like.

[0090] <Determination of the necessity of cleaning the suction nozzle in the suction nozzle cleaning device>

[0091] In the present embodiment, the nozzle cleaning device 20 obtains usage information of the nozzle 50 from the server 11, and determines whether the nozzle 50 needs to be cleaned based on the usage information. Figure 8 , the process of determining whether or not cleaning of the suction nozzle 50 in the suction nozzle cleaning device 20 is necessary is described.

[0092] First, the operator moves the nozzle holder 61 containing the nozzle 50 into the nozzle cleaning device 20 and sets it in the setting part 21 (S20). The control part 25 of the nozzle cleaning device 20 causes the shooting part 22 to shoot the identification mark 69 of the nozzle holder 61. The control part 25 performs image processing on the captured image to obtain the identification information of the nozzle holder 61 (S21). Based on the identification information of the nozzle holder 61, the control part 25 obtains the identification information of each nozzle 50 held at each holding position and the nozzle information of each nozzle 50 associated with the identification information of each nozzle 50 from the server 11 (S22). It should be noted that, unlike the above, the control part 25 may cause the shooting part 22 to shoot the identification mark 56 of each nozzle 50 and perform image processing on the captured image to obtain the identification information of each nozzle 50. The nozzle information includes the above-mentioned usage information.

[0093] The control unit 25 determines whether to clean the suction nozzle 50 for each suction nozzle 50 based on the usage information of the suction nozzle 50. For example, the control unit 25 determines whether the number of times the suction nozzle 50 is used is greater than or less than a preset threshold value (maximum number of times used) (S23). The threshold value of the number of times used here can, for example, refer to past production performance, and the number of times used when the suction errors of the suction nozzle 50 begin to occur frequently when the number of times used is exceeded is set as the threshold. When the number of times the suction nozzle 50 is used is greater than the threshold (S23: Yes), the control unit 25 determines that the suction nozzle 50 needs to be cleaned, and causes the cleaning unit 23 to clean the suction nozzle 50 (S24). Here, the threshold value that serves as a judgment basis is stored in the server 11 or the control unit 25 of the nozzle cleaning device 20. In addition, when the nozzle holder 61 is transferred to the nozzle cleaning device 20, the operator may indicate the threshold value to the control unit 25 of the nozzle cleaning device 20.

[0094] When the number of times the suction nozzle 50 is used is less than the threshold value (S23: No), the control unit 25 may also determine whether the suction nozzle 50 needs to be cleaned based on the suction error information. For example, the control unit 25 determines whether it is the suction nozzle 50 that frequently caused suction errors during the previous production period (S25). If it is the suction nozzle 50 in which the number of suction errors is greater than the threshold value (S25: Yes), the control unit 25 determines that the suction nozzle 50 needs to be cleaned, and cleans the suction nozzle 50 (S24).

[0095] The control unit 25 may also determine whether the suction nozzle 50 needs to be cleaned based on the appearance information of the suction nozzle 50 when the number of occurrences of suction errors of the suction nozzle 50 is less than a threshold value (S25: No). For example, the control unit 25 determines whether there is foreign matter attached to the suction nozzle 50 based on the captured image captured in the component mounting device 30 (S26). When there is foreign matter attached (S26: Yes), the control unit 25 determines that the suction nozzle 50 needs to be cleaned, and cleans the suction nozzle 50 (S26). When there is no foreign matter attached to the suction nozzle 50 (S26: No), the control unit 25 determines that there is no need to clean the suction nozzle 50, and does not clean the suction nozzle 50 (S27).

[0096] It should be noted that, in the present embodiment, the need for cleaning the suction nozzle 50 is determined by S23, S25, and S26, but the need for cleaning the suction nozzle 50 only needs to include at least one step of determination based on usage information. For example, the following structure may be adopted: the need for cleaning the suction nozzle 50 is determined by S23, but not by S25 and S26, and when the number of times of use is less than the threshold value (S23: No), the control unit 25 does not clean the suction nozzle 50. In addition, when the result of the need for cleaning the suction nozzle 50 is that the suction nozzle 50 is not to be cleaned, the control unit 25 may also notify the operator of the identification information of the suction nozzle 50 that is not to be cleaned.

[0097] The control unit 25 determines whether or not the cleaning of the suction nozzle 50 is necessary, and causes the cleaning unit 23 to clean only the suction nozzle 50 that should be cleaned. In this embodiment, the need for cleaning the suction nozzle 50 is determined based on the usage information of the suction nozzle 50, and the suction nozzle 50 that is determined not to be cleaned is not cleaned, so that the time and cost required for cleaning the suction nozzle 50 can be reduced.

[0098] <Storage of maintenance information in the nozzle cleaning device to the server>

[0099] In the present embodiment, the nozzle cleaning device 20 stores maintenance information, which is information related to cleaning and inspection of the nozzle 50, in the server 11. The maintenance information is included in the nozzle information. Fig. 9 , the process of saving the maintenance information in the nozzle cleaning device 20 to the server 11 is described.

[0100] As described above, after determining whether or not cleaning of the suction nozzle 50 is necessary (S30), the control unit 25 of the suction nozzle cleaning device 20 causes the cleaning unit 23 to clean only the suction nozzle 50 that should be cleaned (S31). The control unit 25 stores cleaning information as information related to the cleaning status of each suction nozzle 50, and saves the cleaning information in the server 11 in association with the identification information of the suction nozzle 50 at a predetermined timing (S32). Here, the cleaning information is included in the maintenance information. The cleaning information includes, for example, whether each suction nozzle 50 has been cleaned, and information on the processes implemented when the cleaning action includes multiple processes. The so-called predetermined timing includes, for example, when cleaning is completed, when the inspection after cleaning is completed, and the timing indicated by the operator.

[0101] In the present embodiment, after the control unit 25 has completed the cleaning of all the suction nozzles 50 that should be cleaned according to the judgment of the need for cleaning among the plurality of suction nozzles 50 accommodated in the suction nozzle holder, it causes the inspection unit 24 to inspect all the suction nozzles 50 including the unwashed suction nozzles 50 (S33). It should be noted that the timing of the inspection of the suction nozzles 50 and which suction nozzle 50 among the plurality of suction nozzles 50 held in the suction nozzle holder 61 is to be inspected may be different from the above and may be instructed by the operator.

[0102] The control unit 25 causes the inspection unit 24 to inspect each suction nozzle 50 (S33). The inspection of the suction nozzle 50 includes the inspection of the clogging of the suction nozzle 50. As described above, the inspection of the clogging of the suction nozzle 50 can be performed by processing the image captured by the camera. In addition, the inspection of the clogging of the suction nozzle 50 can also be performed by measuring the flow rate of the air passing through the suction nozzle 50.

[0103] In the present embodiment, the control unit 25 determines whether the inspection of the suction nozzle 50 is qualified or not based on the inspection result of the suction nozzle 50 (S34). For example, the control unit 25 determines that the inspection is qualified when the area of ​​the through hole 55 in the image obtained by photographing the suction nozzle 50 from below is greater than a predetermined reference area, and determines that the inspection is unqualified when it is less than the reference area. In addition, the control unit 25 may also determine that the inspection is qualified when the flow rate of air passing through the suction nozzle 50 is greater than a predetermined reference flow rate, and determine that the inspection is unqualified when it is less than the reference flow rate. The control unit 25 may also be configured as follows: in the case of a suction nozzle 50 that fails the inspection, a warning is issued to the operator.

[0104] The inspection of the suction nozzle 50 may include an inspection of the appearance of the suction nozzle 50 (appearance inspection). When the control unit 25 determines that the suction nozzle 50 is missing through the appearance inspection, it may determine that the inspection is unsatisfactory.

[0105] The information related to the above-mentioned inspection is set as inspection information and included in the maintenance information. The inspection information includes at least one of the inspection result and the pass or fail of the inspection. The inspection information of the present embodiment includes both the inspection result and the pass or fail of the inspection. The control unit 25 stores the inspection information of each suction nozzle 50 in the server 11 (S35) at a predetermined timing in association with the identification information of the suction nozzle 50. Here, the so-called predetermined timing may include, for example, when the inspection is completed, the timing indicated by the operator, etc. It should be noted that the following structure may also be used: the pass or fail judgment of the inspection of the present embodiment (S34) is omitted, and the control unit 25 only stores the inspection result of the suction nozzle 50 in the server 11.

[0106] <Determination of whether the suction nozzle in the component mounting device can be used>

[0107] In the present embodiment, the component mounting device 30 obtains nozzle information including maintenance information of the nozzle 50 from the server 11, and determines whether the nozzle 50 can be used for production based on the nozzle information. Fig.10 , the process of determining whether the suction nozzle 50 in the component mounting device 30 can be used is described.

[0108] Before starting production, the control unit 43 of the component mounting device 30 causes the first camera 40 to photograph the identification mark 69 of the nozzle holder 61. The control unit 43 performs image processing on the photographed image to obtain the identification information of the nozzle holder 61. Based on the identification information of the nozzle holder 61, the control unit 43 obtains the identification information of each nozzle 50 held at each holding position from the server 11 (S40). It should be noted that, unlike the above, the control unit 43 may cause the first camera 40 to photograph the identification mark 56 of each nozzle 50, and perform image processing on the photographed image, thereby obtaining the identification information of each nozzle 50. It should be noted that the identification information of the nozzle 50 installed on the nozzle shaft since the last production is stored in the control unit 43.

[0109] The control unit 43 obtains nozzle information of the nozzles 50 stored in the nozzle holder 61 and the nozzles 50 mounted on the mounting head 37 from the server 11 (S41). The control unit 43 performs the following usability determination on the nozzles 50 of the type scheduled to be used in this production.

[0110] The control unit 43 determines whether the suction nozzle 50 has not been used since the last cleaning (S42). Specifically, if the number of times the suction nozzle 50 has been used is 0 times, it is determined that it has not been used after cleaning. When the suction nozzle 50 has not been used after cleaning (S42: Yes), the control unit 43 determines whether the suction nozzle 50 can be used based on the inspection information performed after cleaning. For example, in the present embodiment, the pass or fail of the inspection is included in the inspection information, and when the suction nozzle 50 has passed the inspection (S43: Yes), the control unit 43 determines that the suction nozzle 50 can be used (S44). When the suction nozzle 50 has failed the inspection (S43: No), the control unit 43 determines that the suction nozzle 50 cannot be used (S45).

[0111] It should be noted that, unlike the present embodiment, when only the inspection result is included in the maintenance information and the pass or fail of the inspection is not included in the maintenance information, the control unit 43 can also determine whether the suction nozzle 50 can be used by performing the same processing as the above-mentioned inspection pass or fail determination processing.

[0112] When the suction nozzle 50 is not unused after cleaning (S42: No), that is, when it is used after cleaning, the control unit 43 determines whether the suction nozzle 50 can be used based on the usage information. For example, in the present embodiment, the usage information includes the number of times the suction nozzle 50 is used. When the number of times the suction nozzle 50 is used is above the threshold value, or it is expected to exceed the threshold value in this production (S46: Yes), the control unit 43 determines that the suction nozzle 50 is not usable (S45). When the number of times the suction nozzle 50 is used is less than the threshold value and it is not expected to exceed the threshold value in this production (S46: No), the control unit 43 determines that the suction nozzle 50 can be used (S44).

[0113] The control unit 43 only installs the suction nozzles 50 that are determined to be usable in the above-mentioned determination of the usability of the suction nozzles 50 on the suction nozzle shaft for production. The control unit 43 does not use the suction nozzles 50 that are determined to be unusable for production. In addition, the control unit 43 can also be configured as follows: when the number of suction nozzles 50 determined to be unusable exceeds a certain number, a warning is issued to the operator.

[0114] In this embodiment, the use of the suction nozzle 50 for production is determined based on the suction nozzle information including the maintenance information, and the suction nozzle 50 that is not suitable for production is not used for production. Therefore, for example, it is possible to prevent the suction nozzle 50 installed in the mounting head 37 from clogging during production and stopping production. Therefore, the efficiency of production can be improved.

[0115] <Sharing of nozzle information among multiple component mounting devices>

[0116] In the present embodiment, as described above, the component mounting system 10 includes two component mounting devices 30 (a first component mounting device 30A and a second component mounting device 30B), and the identification information of the nozzle holder 61 of each component mounting device 30 and the holding position of the nozzle holder 61 are associated with the identification information of each nozzle 50 and stored in the server 11.

[0117] The second component mounting device 30B can obtain the nozzle information of the nozzle 50 held by the nozzle holder 61 of the first component mounting device 30A. In addition, the first component mounting device 30A can obtain the nozzle information of the nozzle 50 held by the nozzle holder 61 of the second component mounting device 30B. According to such a structure, for example, in the second component mounting device 30B, the nozzle 50 accommodated in the nozzle holder 61 of the first component mounting device 30A can be used. Fig.11 , a flow of using the suction nozzle 50 held by the suction nozzle holder 61 of the first component mounting device 30A in the second component mounting device 30B will be described.

[0118] Before production starts, the control unit 43 of the second component mounting device 30B is in accordance with the above-mentioned process (refer to Fig.10 ) Similarly, the usability of the suction nozzle 50 is determined (S50). When it is determined that the number of usable suction nozzles 50 is the same as or greater than the number required by the production plan (S51: No), the control unit 43 of the second component mounting device 30B controls the head unit 36 ​​to mount the suction nozzle 50 (S52) and starts production (S53).

[0119] When it is determined that the number of available suction nozzles 50 is insufficient relative to the number required by the production plan (S51: Yes), the control unit 43 of the second component mounting device 30B obtains the suction nozzle information of the suction nozzle 50 held by the suction nozzle holder 61 of the first component mounting device 30A from the server 11 (S54). The control unit 43 of the second component mounting device 30B compares the model and number of each model of the suction nozzles 50 held by the suction nozzle holder 61 of the first component mounting device 30A with the model and number of each model of the suction nozzles 50 that are insufficient in the production of the second component mounting device 30B, and determines whether the insufficient suction nozzles 50 are held by the suction nozzle holder 61 of the first component mounting device 30A in the required number (S55).

[0120] When the required number of insufficient suction nozzles 50 exist in the suction nozzle holder 61 of the first component mounting device 30A (S55: Yes), the control unit 43 of the second component mounting device 30B determines, based on the production plan, etc., whether the production of the first component mounting device 30A is not hindered (i.e., whether production is possible) when the suction nozzle holder 61 is removed from the first component mounting device 30A (S56).

[0121] When there is no obstacle in the production of the first component mounting device 30A (S56: Yes), the control unit 43 of the second component mounting device 30B determines whether the suction nozzle 50 held by the suction nozzle holder 61 of the first component mounting device 30A can be used for the production of the second component mounting device 30A based on the maintenance information (S57). Specifically, S57 is Fig.10 After S42 for determining whether the use is possible, the control unit 43 of the second component mounting device 30B determines whether the required number of nozzles 50 that are determined to be usable for production by the second component mounting device 30B are stored in the nozzle holder 61 of the first component mounting device 30A (S58).

[0122] When the required number of nozzles 50 that can be used for production exists in the nozzle holder 61 of the first component mounting device 30A (S58: Yes), the control unit 43 of the second component mounting device 30B sends a message to the operator to instruct the nozzle holder 61 of the first component mounting device 30A to be moved to the second component mounting device 30B, and the operator moves the nozzle holder 61 of the first component mounting device 30A to the second component mounting device 30B (S59). Then, the insufficient number of nozzles 50 are installed (S52), and production is started (S53).

[0123] As described above, according to the present embodiment, when the required number of suction nozzles 50 that can be used for production cannot be ensured in the second component mounting device 30B, the suction nozzles 50 of the suction nozzle holder 61 of the first component mounting device 30A can sometimes be used. Therefore, it is possible to suppress a decrease in productivity in the second component mounting device 30B.

[0124] It should be noted that, when the required number of suction nozzles 50 that are insufficient in the production of the second component mounting device 30B is not in the suction nozzle holder 61 of the first component mounting device 30A (S55: No), when the production of the first component mounting device 30A is hindered when the suction nozzle holder 61 is moved (S56: No), and when the required number of available suction nozzles 50 are not in the suction nozzle holder 61 (S58: No), for example, the control unit 43 of the second component mounting device 30B sends a message to the operator instructing the second component mounting device 30B to replenish the suction nozzles 50, and the operator replenishes the suction nozzles 50 (S60). Then, the insufficient suction nozzles 50 are installed (S52), and production is started (S53).
