[0014] (Background to this disclosure) The background to the present disclosure will be explained. A component mounting device picks up and removes components stored in a tray, and then mounts the components on a board. For example, if the tray has a large dimensional error or is significantly deformed in shape, the height positions of the components stored in the tray will vary, making it more likely that components will be picked up incorrectly. Therefore, the component mounting device of the comparative example recognizes the height positions of the components before picking them up.

[0015] FIG. 1 is a diagram showing an example of the operation of a component mounting apparatus 101 of the comparative example.

[0016] 1(a) shows a state in which a component C is stored in the storage section 6a of the tray 6. The component mounting device 101 of the comparative example first lowers the suction nozzle 10a and recognizes the position where the suction nozzle 10a comes into contact with the upper surface of the component C as the height position of the component C. Then, based on the recognized height position, the component mounting device 101 uses the suction nozzle 10a to pick up the component C and removes the component C from the tray 6 (see FIG. 1(b)).

[0017] However, in an actual production site, there are times when components C are not stored in the storage section 6a of the tray 6. This situation where components C are not stored in the storage section 6a can occur for various reasons, such as incorrect storage of components C in the tray 6, components C falling off during tray transport, or when a tray 6 from which some of the multiple components C have been removed is collected and the collected tray 6 is reused.

[0018] FIG. 2 is a diagram showing another example of the operation of the component mounting apparatus 101 of the comparative example.

[0019] 2(a) shows a state in which some of the storage sections 6a among the plurality of storage sections 6a do not store a component C. If a component C is not stored in a storage section 6a, the suction nozzle 10a comes into contact with the inner bottom surface 6b of the storage section 6a when it is lowered, and the component mounting device 101 recognizes the height position of the inner bottom surface 6b of the storage section 6a as the height position of the component C.

[0020] Therefore, as shown in FIG. 2(b), when the suction nozzle 10a is lowered to perform the suction operation, the suction nozzle 10a picks up the tray 6. Then, if the suction nozzle 10a is raised while the tray 6 is being suctioned, the tray 6 will rise as shown in FIG. 2(c), causing a problem in which components C stored in other storage sections 6a will fly off. In this case, it will be necessary to stop the operation of the component mounting device 101 and perform cleaning, etc., which will reduce the productivity of the component mounting process. Furthermore, if the scattered components C become unusable, the productivity of the component mounting process will also decrease.

[0021] The component mounting apparatus and the like of the present disclosure have the following configuration in order to prevent a decrease in productivity in the component mounting process.

[0022] Hereinafter, embodiments will be described in detail with reference to the drawings. Note that the embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component placement and connection forms, steps, and step order shown in the following embodiments are merely examples and are not intended to limit the present disclosure. In the drawings, the X and Y directions indicate the horizontal direction, and the Z direction indicates the vertical direction.

[0023] (Embodiment 1) [Component mounting equipment configuration] The configuration of the component mounting apparatus according to the first embodiment will be described with reference to FIGS.

[0024] Fig. 3 is a diagram showing the component mounting apparatus 1 according to embodiment 1 as viewed from above. Fig. 4 is a diagram showing a part of the component mounting apparatus 1 as viewed from the side.

[0025] 3, component mounting apparatus 1 includes a board transport unit 2 and a component mounting unit 50. Board transport unit 2 is provided on a base 1a of component mounting apparatus 1 and is arranged along the X direction. Board transport unit 2 transports board 3 on which component C is to be mounted, and places board 3 at component mounting position p2.

[0026] Component supply units 4A and 4B are disposed on the sides in the Y direction relative to the position of the board transport unit 2, supplying components C to be mounted on the board 3. The components C are, for example, surface-mount electronic components. The components C are supplied in a component storage unit such as a carrier tape and a tray 6.

[0027] The component supply unit 4B is provided with a plurality of tape feeders 14. The tape feeders 14 feed the carrier tape storing the components C by a pitch, thereby supplying the components C to the component take-out position p1 of the component supply unit 4B.

[0028] The component supply unit 4A is provided with a tray feeder 5 shown in Fig. 4. The tray feeder 5 conveys a tray 6 storing a plurality of components C, thereby supplying the components C to a component pick-up position p1 of the component supply unit 4A.

[0029] The tray 6 is made of a lightweight resin material. The tray 6 is formed, for example, by embossing a thin resin sheet. The tray 6 is provided with a plurality of storage sections 6a for storing a plurality of components C (see FIG. 7). The plurality of storage sections 6a are formed in a matrix along the X and Y directions. The storage sections 6a have a concave shape that is recessed from the upper surface of the tray 6 toward the lower surface. The storage section 6a has an inner bottom surface 6b parallel to the upper surface of the tray 6 and an inner side surface connecting the upper surface and the inner bottom surface 6b. The components C are stored in the tray 6 in a state where they abut against the inner bottom surface 6b of the storage section 6a.

[0030] The tray 6 is removed from the magazine 23 by the tray feeder 5 and transported to the component removal position p1. At the component removal position p1, the tray 6 is positioned at a predetermined position in the X, Y, and Z directions. The tray 6 may be placed at the component removal position p1 by its own weight, or may be fixed at the component removal position p1 by a suction force weaker than that of the suction nozzle 10a.

[0031] The component mounting unit 50 shown in FIG. 3 includes a Y-axis moving table 7, X-axis moving tables 8A and 8B, and mounting heads 9A and 9B.

[0032] The Y-axis moving table 7 is disposed along the Y direction. Two X-axis moving tables 8A and 8B are attached to the Y-axis moving table 7. The X-axis moving tables 8A and 8B are disposed corresponding to the component supply units 4A and 4B, respectively, and are movable in the Y direction by the Y-axis moving table 7. Mounting heads 9A and 9B are attached to the X-axis moving tables 8A and 8B, respectively.

[0033] The mounting head 9A can be moved horizontally between the component supply unit 4A and the board 3 by the Y-axis moving table 7 and the X-axis moving table 8A. The mounting head 9B can be moved horizontally between the component supply unit 4B and the board 3 by the Y-axis moving table 7 and the X-axis moving table 8B. The mounting heads 9A and 9B are multiple heads equipped with multiple transfer heads 10. The multiple transfer heads 10 are arranged, for example, along the X direction. A suction nozzle 10a is attached to the lower end of each transfer head 10 (see FIG. 4). The suction nozzle 10a can be raised and lowered in the Z direction by a linear motion mechanism provided on the transfer head 10. The suction nozzle 10a can suck and hold the component C by vacuum suction.

[0034] Each of the mounting heads 9A and 9B is provided with a first camera 11 for recognizing the position of the board 3. In this embodiment, the first camera 11 is used to capture an image of the component removal position p1 and detect whether or not a component C to be removed is present at the component removal position p1. In other words, the first camera 11 is used for both recognizing the position of the board 3 and detecting whether or not a component C to be removed is present at the component removal position p1. The camera for detecting whether or not a component C is present may be the same as the camera for recognizing the position of the board 3, but is not limited to this and may be a different camera. In FIG. 3, the first camera 11 is provided laterally in the Y direction relative to the mounting head 9A or 9B. However, the present invention is not limited to this and the first camera 11 may be provided laterally in the X direction relative to the mounting head 9A or 9B.

[0035] A second camera 13 is provided between the component supply units 4A, 4B and the board transport unit 2 to recognize the position and posture of the component C sucked and held by the suction nozzle 10a. The second camera 13 is positioned below the mounting heads 9A, 9B and captures images of the component C held by the mounting heads 9A, 9B from below. For example, the component mounting device 1 recognizes the holding position, posture, etc. of the component C by capturing an image of the component C sucked by the suction nozzle 10a from below while the mounting heads 9A, 9B are moving.

[0036] Furthermore, the mounting heads 9A and 9B are provided with a measuring unit 48 that measures the height position of the component C at the component pick-up position p1. The measuring unit 48 is provided on a drive motor (not shown) that raises and lowers the suction nozzle 10a. The measuring unit 48 measures the height position of the component C based on fluctuations in the torque value of the drive motor when the suction nozzle 10a is lowered. For example, when the suction nozzle 10a is lowered and comes into contact with the top surface of the component C, the torque value increases suddenly. Therefore, for example, the component mounting device 1 determines the position when the torque value exceeds a predetermined value as the height position of the component C. Note that when the height position of the component C is measured using the suction nozzle 10a, suction by the suction nozzle 10a is turned off.

[0037] The height position of the component C may be the height of the upper surface of the component C when a predetermined height of the suction nozzle 10a is used as a reference, or may be the height of the upper surface of the component C when the height of the base 1a of the component mounting apparatus 1 is used as a reference. After measuring the height position of the component C using the measuring unit 48, the component mounting apparatus 1 slightly raises the suction nozzle 10a so that the suction nozzle 10a is separated from the upper surface of the component C before performing the next suction operation.

[0038] The component mounting apparatus 1 determines the height position of the suction nozzle 10a when suctioning the component C and the timing of suction-on, based on the height position of the component C measured by the measuring unit 48. The mounting heads 9A and 9B use the suction nozzle 10a to suction and pick up the component C, and then mount the picked component C on the board 3, based on the adjusted height position and timing.

[0039] Fig. 5 is a block diagram of the component mounting apparatus 1. Fig. 5 also shows a component mounting system 80 including the component mounting apparatus 1 and a server apparatus 90. The component mounting apparatus 1 is communicatively connected to the server apparatus 90 via a communication network 82 such as a LAN (Local Area Network).

[0040] 5, component mounting apparatus 1 includes control unit 40, memory unit 41, communication unit 43, board transport unit 2, component supply units 4A and 4B, and second camera 13. Component mounting apparatus 1 also includes first camera 11, determination unit 45, measurement unit 48, and component mounting unit 50. In FIG. 5, determination unit 45 is provided within control unit 40, but is not limited thereto and may be provided outside control unit 40 as long as it is within component mounting apparatus 1.

[0041] The configurations of the board transport unit 2, component supply units 4A and 4B, and second camera 13 are as described above. Here, we will explain the configurations of the control unit 40, memory unit 41, communication unit 43, first camera 11, determination unit 45, measurement unit 48, and component mounting unit 50. In the following, we will mainly explain the configuration of the mounting head 9A side of the mounting heads 9A and 9B of the component mounting unit 50.

[0042] The communication unit 43 is a communication module, and communicates with the server device 90 via the communication network 82 .

[0043] The control unit 40 is a computing device with CPU functionality, and controls the driving of the board transport unit 2, the component mounting unit 50, and the component supply units 4A and 4B based on the program and mounting data 42 stored in the memory unit 41. The mounting data 42 includes information regarding the specifications (e.g., type, shape, size, color, etc.) of the components C to be mounted on the board 3. The mounting data 42 may also include information regarding the traceability and usage history of the tray 6. The traceability information includes information regarding the equipment that stored the components C on the tray 6, the transport route of the tray 6 that stored the components C, and the inspection results of the tray 6 that stored the components C.

[0044] Furthermore, based on the image information acquired by the first camera 11, the control unit 40 recognizes the presence or absence of the component C at the component pick-up position p1 of the component supply unit 4A, and the position of the board 3. Based on the image information acquired by the second camera 13, the control unit 40 also recognizes the position and posture of the component C picked up by the suction nozzle 10a.

[0045] The first camera 11 captures an image of the storage section 6a of the tray 6 located at the component removal position p1. The first camera 11 is attached to the mounting head 9A of the component mounting unit 50. The component mounting apparatus 1 moves the mounting head 9A to move the first camera 11 above the storage section 6a of the tray 6, and detects whether or not a component C is present in the storage section 6a of the tray 6.

[0046] For example, the first camera 11 captures an image of the storage section 6a when the mounting head 9A is moving or when it is stopped. In this example, the first camera 11 captures an image of one storage section 6a, but this is not limited to this, and the first camera 11 may capture an image of multiple storage sections 6a simultaneously. The first camera 11 may also capture an image of another storage section 6a different from the specified storage section 6a when the suction nozzle 10a is positioned and stopped above the specified storage section 6a. Information captured by the first camera 11 is output to the determination unit 45.

[0047] The determination unit 45 determines whether or not a component C is present in the storage section 6a of the tray 6 based on the information captured by the first camera 11. The determination unit 45 determines the presence or absence of the component C by comparing (image matching) the image information of the component C acquired by the first camera 11 with a sample image of the determination candidate. The determination unit 45 may determine the presence or absence of the component C based on the image information of the component C and information about the shape, size, and color of the component C stored in the memory unit 41. The determination unit 45 outputs the determination result regarding the presence or absence of the component C to the measurement unit 48. The determination result regarding the presence or absence of the component C is also output to the memory unit 41 and the server device 90 as history information indicating the presence or absence of the component C in the used tray 6.

[0048] When it is determined that the component C is present in the storage section 6a, the measurement section 48 measures the height position of the component C present in the storage section 6a.

[0049] On the other hand, if it is determined that there is no component C in the storage section 6a, the measurement unit 48 does not measure the height position of the component C in that storage section 6a. In this case, the component mounting device 1 moves the first camera 11 together with the mounting head 9A to above another storage section 6a to detect the presence or absence of a component C in that other storage section 6a. The other storage section 6a is a storage section 6a from which a component C has not yet been removed, among the multiple storage sections 6a. In this way, if the determination unit 45 determines that there is no component C in the storage section 6a, it determines whether there is a component C in another storage section 6a different from the storage section 6a in question. Then, if it is determined that there is a component C in the other storage section 6a, the measurement unit 48 measures the height position of the component C in that other storage section 6a.

[0050] The mounting head 9A of the component mounting unit 50 picks up the component C stored in the tray 6 and mounts it on the board 3 based on the height position of the component C measured by the measuring unit 48.

[0051] As in the component mounting apparatus 1 described above, by determining whether or not there is a component C in the storage section 6a using the determination section 45 before measuring the height position of the component C using the measurement section 48, it is possible to prevent problems from occurring when there is no component C in the storage section 6a of the tray 6. This makes it possible to prevent a decrease in productivity in the component mounting process.

[0052] [Component mounting method] The component mounting method according to the first embodiment will be described with reference to FIGS.

[0053] Fig. 6 is a flowchart showing the component mounting method according to embodiment 1. Fig. 7 is a diagram showing an example of the operation of component mounting apparatus 1. Fig. 8 is a diagram showing another example of the operation of component mounting apparatus 1. Figs. 7 and 8 schematically show cross sections of tray 6, component C, first camera 11, and suction nozzle 10a at component removal position p1.

[0054] As shown in FIG. 7(a), the component mounting apparatus 1 captures an image of a predetermined storage section 6a among the multiple storage sections 6a provided on the tray 6 (step S10). For example, the component mounting apparatus 1 uses the first camera 11 to capture an image of the predetermined storage section 6a. The component mounting apparatus 1 starts capturing an image from the storage section 6a located at the end of the tray 6, but is not limited to this, and may start capturing an image from the storage section 6a located more inward than the end of the tray 6. Information captured by the first camera 11 is output to the determination unit 45.

[0055] The determination unit 45 determines whether or not the component C is present in the storage unit 6a based on the information captured by the first camera 11 (step S20).

[0056] If the determination unit 45 determines that the component C is present in the storage unit 6a (Yes in S20), the measurement unit 48 measures the height position of the component C in the storage unit 6a (step S30), as shown in Fig. 7(b). The measurement unit 48 measures the height position of the component C, for example, based on fluctuations in the torque value of the drive motor when the suction nozzle 10a is lowered, but is not limited to this, and the height position of the component C may also be measured using a strain gauge or the like.

[0057] 7(c), based on the height position of component C measured by measurement unit 48, component mounting unit 50 picks up component C from storage unit 6a and mounts the component C on board 3 (step S40). Specifically, component mounting apparatus 1 picks up component C, recognizes the holding position and posture of component C using second camera 13, and then mounts component C on board 3.

[0058] On the other hand, as shown in Fig. 8(a), if the component C is not stored in the storage unit 6a and the determination unit 45 determines that the component C is not present in the storage unit 6a (No in S20), the component mounting apparatus 1 moves the first camera 11 to above another storage unit 6a (step S50), as shown in Fig. 8(b). The component mounting apparatus 1 then returns to step S10, captures an image of the other storage unit 6a, and determines in step S20 whether or not the component C is present in the other storage unit 6a. If the determination unit 45 determines that the component C is not present in the other storage unit 6a (No in S20), the component mounting apparatus 1 repeats the processes of steps S50, S10, and S20.

[0059] 8(b), when moving the first camera 11 in step S50, the component mounting apparatus 1 may move the first camera 11 onto another storage unit 6a located adjacent in the X direction to the storage unit 6a determined to be free of the component C. Furthermore, if the component mounting apparatus 1 has already taken an image of the other storage unit 6a in a previous image capture, it may omit steps S50 and S10 and directly perform the determination in step S20.

[0060] If the determination unit 45 determines that a component C is present in another storage section 6a (Yes in S20), the measurement unit 48 measures the height position of the component C present in the other storage section 6a (S30), as shown in (c) of Figure 8.

[0061] Based on the height position of the component C measured by the measuring unit 48, the component mounting unit 50 takes out the component C from the other storage unit 6a as shown in Fig. 8(d) and mounts the component C on the board 3 (S40). After that, the component mounting apparatus 1 repeatedly executes the processes of steps S10 to S50.

[0062] As described above, the determining unit 45 determines whether or not the component C is present in each of the plurality of storage units 6a.

[0063] Furthermore, when the determining unit 45 determines that the component C is present, the measuring unit 48 measures the height position of the component C each time it is determined that the component C is present. Furthermore, each time the measuring unit 48 measures the height position of the component C, the component mounting unit 50 takes out the component C stored in the storage unit 6a and mounts it on the board 3 based on the height position measured by the measuring unit 48.

[0064] In this way, by determining whether or not there is a component C in the storage section 6a before measuring the height position of the component C, it is possible to prevent problems from occurring when there is no component C in the storage section 6a of the tray 6. This makes it possible to prevent a decrease in productivity in the component mounting process.

[0065] Although the above example shows measuring the height position of component C each time it is determined that a component C is present, the present invention is not limited to this. For example, when the determination unit 45 determines that a component C is present on the tray 6, the measurement unit 48 may measure the height position of component C only the first time it is determined that a component C is present. In other words, the component mounting apparatus 1 does not need to measure the height positions of all components C. After measuring the height position of a specific component C, the measurement result may be reused as the height positions of other components C. The component mounting unit 50 may remove multiple components C stored on the tray 6 and mount them on the board 3 based on the reused measurement result.

[0066] (Embodiment 2) [Component Mounting System] A component mounting system 80A according to the second embodiment will be described with reference to Fig. 9 and Fig. 10. In the second embodiment, an example will be described in which a determination unit 95 that determines the presence or absence of a component C is provided in a server device 90A.

[0067] FIG. 9 is a block diagram of a component mounting system 80A according to the second embodiment.

[0068] Component mounting system 80A includes a component mounting apparatus 1A that mounts components C on a board 3, and a server apparatus 90A. Component mounting apparatus 1A is communicatively connected to server apparatus 90A via a communication network 82 such as a LAN. While FIG. 9 shows an example in which component mounting system 80A includes one component mounting apparatus 1A, component mounting system 80A may include two or more component mounting apparatuses 1A.

[0069] 9, component mounting apparatus 1A includes a control unit 40, a memory unit 41, a communication unit 43, a board transport unit 2, component supply units 4A and 4B, and a second camera 13. Component mounting apparatus 1A also includes a first camera 11, a judgment request output unit 46, a judgment result acquisition unit 47, a measurement unit 48, and a component mounting unit 50.

[0070] The component mounting apparatus 1A of the second embodiment does not include the determination unit 45 shown in the first embodiment, but includes a determination request output unit 46 and a determination result acquisition unit 47. On the other hand, the server apparatus 90A of the second embodiment includes a determination unit 95 that determines whether or not a component C is present.

[0071] The configurations of memory unit 41, communication unit 43, board transport unit 2, component supply units 4A and 4B, second camera 13, first camera 11, and component mounting unit 50 are the same as those in embodiment 1. Here, the configurations of judgment request output unit 46 and judgment result acquisition unit 47 included in control unit 40, the configuration of measurement unit 48, and the configuration of server device 90A will be described. In Fig. 9, judgment request output unit 46 and judgment result acquisition unit 47 are provided in control unit 40, but are not limited to this and may be provided outside control unit 40 as long as they are within component mounting apparatus 1A.

[0072] The judgment request output unit 46 of the component mounting apparatus 1A outputs to the server device 90A request information i1 requesting a judgment as to whether or not a component C is present in the storage section 6a of the tray 6, based on the image information captured by the first camera 11. The request information i1 includes image information of the component C captured by the first camera 11 and a judgment command requesting the server device 90A to judge the object to be judged. The judgment request output unit 46 outputs the request information i1 to the server device 90A individually for each of the multiple storage sections 6a.

[0073] The server device 90A is a server that manages and controls the entire component mounting system 80. The server device 90A is a calculation device with a CPU function, and includes a storage unit 91, a communication unit 93, and a determination unit 95. The communication unit 93 is a communication module that communicates with the component mounting device 1A via the communication network 82.

[0074] The server device 90A controls the operation of the component mounting system 80A based on the program and mounting data 92 stored in the storage unit 91. The mounting data 92 includes information on the specifications (e.g., type, shape, size, color, etc.) of the component C to be mounted on the board 3. The mounting data 92 may also include information on the traceability and usage history of the tray 6.

[0075] The determination unit 95 determines whether or not a component C is present in the storage unit 6a based on the request information i1 output from the component mounting device 1A. For example, the determination unit 95 compares the image of the component C included in the request information i1 with a sample image of a determination candidate to determine the presence or absence of the component C. The determination unit 95 may determine the presence or absence of the component C based on the image information of the component C included in the request information i1 and information related to the shape, size, and color of the component C stored in the storage unit 91.

[0076] The server device 90A outputs result information i2 indicating the determination result of whether or not components C are present in the storage unit 6a to the component mounting device 1A. The server device 90A outputs this result information i2 to the component mounting device 1A via the communication unit 93. The result information i2 is stored in the memory unit 91 as history information indicating the presence or absence of components C in the used tray 6.

[0077] The determination result acquisition unit 47 of the component mounting apparatus 1A acquires the result information i2 output from the server device 90A. The control unit 40 controls the operation of the measurement unit 48 based on the result information i2.

[0078] When it is determined that the component C is present in the storage section 6a, the measurement section 48 measures the height position of the component C present in the storage section 6a.

[0079] On the other hand, if it is determined that there are no components C in the storage unit 6a, the measurement unit 48 does not measure the height position of the components C in that storage unit 6a. In this case, the component mounting device 1A moves the first camera 11 together with the mounting head 9A to above the other storage unit 6a to capture an image of the other storage unit 6a. Then, the judgment request output unit 46 outputs request information i1 to the server device 90A, requesting a judgment as to whether there are components C in the other storage unit 6a.

[0080] The determination unit 95 of the server device 90A determines whether or not the component C is present in the other storage units 6a based on the request information i1 output from the component mounting device 1A. Then, the server device 90A outputs result information i2 indicating the determination result indicating whether or not the component C is present in the other storage units 6a to the component mounting device 1A.

[0081] The determination result acquisition unit 47 of the component mounting apparatus 1A acquires the result information i2 output from the server device 90A. The control unit 40 controls the operation of the measurement unit 48 based on the result information i2.

[0082] When it is determined that the component C is present in the other storage section 6a, the measuring section 48 measures the height position of the component C present in the other storage section 6a.

[0083] The mounting head 9A of the component mounting unit 50 picks up the component C stored in the tray 6 and mounts it on the board 3 based on the height position of the component C measured by the measuring unit 48.

[0084] As in the component mounting system 80A described above, by obtaining the determination result as to whether or not the component C is present in the storage section 6a from the server device 90A before measuring the height position of the component C by the measurement section 48, it is possible to prevent problems from occurring when the component C is not present in the storage section 6a of the tray 6. This makes it possible to prevent a decrease in productivity in the component mounting process.

[0085] FIG. 10 is a sequence diagram showing the operation of the component mounting system 80A according to the second embodiment.

[0086] The component mounting apparatus 1A captures an image of the component C to be judged (step S101), and transmits request information i1 including the captured image and a judgment command to the server apparatus 90A (step S102). The judgment command includes a facility number identifying the component mounting apparatus 1A, a transaction number (unique ID) specific to the judgment command, a command number indicating the type of judgment, a group of parameters specific to the command indicating the specific content of the judgment, and the full file path of the transmitted image. The captured image and the judgment command are associated with each other.

[0087] The server device 90A receives the image of component C and the determination command output from the component mounting device 1A and executes the determination command (step S103). For example, the server device 90A reads the image file based on the full file path of the image included in the determination command, and executes the determination process based on the command number and parameter group. The server device 90A transmits result information i2 including the determination result regarding the presence or absence of component C to the component mounting device 1A (step S104).

[0088] The component mounting apparatus 1A receives the result information i2 from the server apparatus 90A and executes processing according to the determination result (step S105). For example, if the result information i2 indicates that the component C is present in the storage unit 6a, the component mounting apparatus 1A measures the height position of the component C in the storage unit 6a. Then, based on the height position of the component C measured by the measurement unit 48, the component mounting apparatus 1A removes the component C from the storage unit 6a and mounts it on the board 3.

[0089] In this way, by obtaining the determination result as to whether or not the component C is present in the storage section 6a from the server device 90A before measuring the height position of the component C, it is possible to prevent problems from occurring when the component C is not present in the storage section 6a of the tray 6. This makes it possible to prevent a decrease in productivity in the component mounting process.

[0090] In the component mounting system 80A described above, the determination unit 95 determines the presence or absence of components C for each of the multiple storage units 6a, and the measurement unit 48 measures the height position of the component C each time the determination unit 95 determines that a component C is present. However, this is not limiting. For example, in the component mounting apparatus 1A, when the determination unit 95 determines that a component C is present in the tray 6, the measurement unit 48 may measure the height position of the component C only the first time that the determination unit 95 determines that a component C is present. In other words, the component mounting apparatus 1A does not need to measure the height positions of all components C. After measuring the height position of a specific component C, the measurement result may be reused as the height positions of other components C. The component mounting unit 50 may remove multiple components C stored in the tray 6 and mount them on the board 3 based on the reused measurement result.

[0091] Furthermore, component mounting system 80A may further include a relay device, and server device 90A may be connected to component mounting apparatus 1A via the relay device. The relay device may be a management computer also known as an LNB (Line Network Box), which not only manages the production of mounted boards by component mounting system 80A but also creates various parameters used by component mounting apparatus 1A. For example, information output from component mounting apparatus 1A to server device 90A via the relay device is substantially the same as information output from component mounting apparatus 1A to server device 90A. Furthermore, information output from server device 90A to component mounting apparatus 1A via the relay device is substantially the same as information output from server device 90A to component mounting apparatus 1A.

[0092] (summary) An example of a component mounting apparatus according to one aspect of the present disclosure will be described below.

[0093] The component mounting device 1 of Example 1 includes a determination unit 45 that determines whether or not a component C is present in a storage unit 6a of a tray 6 having a plurality of storage units 6a for storing the component C, a measurement unit 48 that measures the height position of the component C in the storage unit 6a when the determination unit 45 determines that the component C is present in the storage unit 6a, and a component mounting unit 50 that removes the component C from the storage unit 6a and mounts it on the board 3 based on the height position of the component C measured by the measurement unit 48.

[0094] In this way, by determining whether or not there is a component C in the storage section 6a by the determination section 45 before measuring the height position of the component C by the measurement section 48, it is possible to prevent problems from occurring when there is no component C in the storage section 6a of the tray 6. This makes it possible to prevent a decrease in productivity in the component mounting process.

[0095] The component mounting device 1 of Example 2 is the component mounting device described in Example 1, and when the determination unit 45 determines that there is no component C in the storage unit 6a, it determines whether there is a component C in another storage unit 6a different from the storage unit 6a in question, and when the determination unit 45 determines that there is a component C in the other storage unit 6a, the measurement unit 48 measures the height position of the component C in the other storage unit 6a, and the component mounting unit 50 may remove the component C from the other storage unit 6a and mount it on the board 3 based on the height position of the component C measured by the measurement unit 48.

[0096] According to this, when there are no components C in a storage section 6a, the storage section 6a is not sucked, but the height positions of the components C in other storage sections 6a are measured, and the components C stored in the other storage sections 6a can be removed. This makes it possible to prevent problems from occurring when there are no components C in the storage sections 6a of the tray 6. This makes it possible to prevent a decrease in productivity in the component mounting process.

[0097] The component mounting apparatus 1 of Example 3 is the component mounting apparatus described in Example 1 or 2, and the determining unit 45 may determine the presence or absence of the component C individually for each of the plurality of storage units 6a.

[0098] This makes it possible to determine whether or not components C are present in each of the storage sections 6a before measuring the height position of the components C. This makes it possible to prevent problems from occurring when components C are not present in the storage sections 6a of the tray 6. This makes it possible to prevent a decrease in productivity in the component mounting process.

[0099] The component mounting device 1 of Example 4 is a component mounting device described in any one of Examples 1 to 3, and further includes a camera (first camera 11) that captures an image of the storage section 6a, and the judgment unit 45 may judge whether or not a component C is present in the storage section 6a based on the information captured by the camera.

[0100] According to this, before measuring the height position of the component C, the camera can capture an image of the storage section 6a to determine whether or not the component C is present in the storage section 6a. This can prevent problems from occurring when the component C is not present in the storage section 6a of the tray 6. This can prevent a decrease in productivity in the component mounting process.

[0101] The component mounting apparatus 1 of Example 5 is a component mounting apparatus described in any one of Examples 1 to 4, and when the determination unit 45 determines that a component C is present, the measurement unit 48 measures the height position of the component C each time it is determined that a component C is present, and the component mounting unit 50 may remove the component C and mount it on the board 3 based on the height position of the component C measured by the measurement unit 48.

[0102] In this way, by measuring the height position of the component C every time there is a component C in the storage section 6a, the component C can be reliably removed based on the measured height position of the component C. This makes it possible to prevent problems from occurring when removing the component C. This makes it possible to prevent a decrease in productivity in the component mounting process.

[0103] The component mounting apparatus 1 of Example 6 is a component mounting apparatus described in any of Examples 1 to 4, and when the determination unit 45 determines that a component C is present on the tray 6, the measurement unit 48 measures the height position of the component C only the first time that it is determined that the component C is present, and the component mounting unit 50 may remove multiple components C stored on the tray 6 and mount them on the board 3 based on the height position of the component C measured by the measurement unit 48.

[0104] This reduces the number of times the height position of the component C is measured, thereby preventing a decrease in productivity in the component mounting process.

[0105] The component mounting apparatus 1A of Example 7 includes a judgment request output unit 46 that outputs request information i1 to the server device 90A requesting a judgment as to whether or not a component C is present in a storage unit 6a of a tray 6 having a plurality of storage units 6a for storing the component C; a judgment result acquisition unit 47 that acquires result information i2 from the server device 90A indicating the judgment result as to whether or not a component C is present in the storage unit 6a; a measurement unit 48 that measures the height position of the component C in the storage unit 6a when the result information i2 is the judgment result that the component C is present in the storage unit 6a; and a component mounting unit 50 that removes the component C from the storage unit 6a and mounts it on the board 3 based on the height position of the component C measured by the measurement unit 48.

[0106] In this way, by obtaining the determination result as to whether or not the component C is present in the storage section 6a from the server device 90A before the measuring section 48 measures the height position of the component C, it is possible to prevent problems from occurring when the component C is not present in the storage section 6a of the tray 6. This makes it possible to prevent a decrease in productivity in the component mounting process.

[0107] The component mounting apparatus 1A of Example 8 is the component mounting apparatus described in Example 7, and when the result information i2 is a determination result that there is no component C in the storage section 6a, the judgment request output unit 46 outputs request information i1 to the server device 90A to request a determination as to whether or not there is a component C in another storage section 6a different from the storage section 6a in question, the judgment result acquisition unit 47 acquires result information i2 indicating the determination result as to whether or not there is a component C in the other storage section 6a from the server device 90A, and when the result information i2 is a determination result that there is a component C in the other storage section 6a, the measurement unit 48 measures the height position of the component C in the other storage section 6a, and the component mounting unit 50 may remove the component C from the other storage section 6a and mount it on the board 3 based on the height position of the component C measured by the measurement unit 48.

[0108] According to this, when there are no components C in a storage section 6a, the storage section 6a is not sucked, but the height positions of the components C in other storage sections 6a are measured, and the components C stored in the other storage sections 6a can be removed. This makes it possible to prevent problems from occurring when there are no components C in the storage sections 6a of the tray 6. This makes it possible to prevent a decrease in productivity in the component mounting process.

[0109] The component mounting device 1A of Example 9 is the component mounting device described in Example 7 or 8, and the judgment request output unit 46 may output request information i1 to the server device 90A, requesting a judgment of the presence or absence of component C individually for each of the multiple storage sections 6a.

[0110] This makes it possible to determine whether or not components C are present in each of the storage sections 6a before measuring the height position of the components C. This makes it possible to prevent problems from occurring when components C are not present in the storage sections 6a of the tray 6. This makes it possible to prevent a decrease in productivity in the component mounting process.

[0111] The component mounting apparatus 1A of Example 10 is a component mounting apparatus described in any one of Examples 7 to 9, and further includes a camera (first camera 11) that captures an image of the storage section 6a, and the judgment request output unit 46 may output request information i1 including information captured by the camera to the server device 90A.

[0112] According to this, before measuring the height position of the component C, the camera can capture an image of the storage section 6a to determine whether or not the component C is present in the storage section 6a. This can prevent problems from occurring when the component C is not present in the storage section 6a of the tray 6. This can prevent a decrease in productivity in the component mounting process.

[0113] The component mounting apparatus 1A of Example 11 is a component mounting apparatus described in any of Examples 7 to 10, and when the result information i2 is a determination result that a component C is present on the tray 6, the measurement unit 48 measures the height position of the component C each time the result information i2 is acquired, and the component mounting unit 50 may remove the component C and mount it on the board 3 based on the height position of the component C measured by the measurement unit 48.

[0114] In this way, by measuring the height position of the component C every time there is a component C in the storage section 6a, the component C can be reliably removed based on the measured height position of the component C. This makes it possible to prevent problems from occurring when removing the component C. This makes it possible to prevent a decrease in productivity in the component mounting process.

[0115] The component mounting apparatus 1A of Example 12 is a component mounting apparatus described in any of Examples 7 to 10, and when the result information i2 is a determination result that a component C is present on the tray 6, the measurement unit 48 measures the height position of the component C only the first time the determination result that a component C is present is obtained, and the component mounting unit 50 may remove multiple components C stored on the tray 6 and mount them on the board 3 based on the height position of the component C measured by the measurement unit 48.

[0116] This reduces the number of times the height position of the component C is measured, thereby preventing a decrease in productivity in the component mounting process.

[0117] A component mounting system 80A of Example 13 includes the component mounting apparatus 1A described in any one of Examples 7 to 12, and a server device 90A that is communicatively connected to the component mounting apparatus 1A. The server device 90A determines whether or not a component C is present in the storage unit 6a based on request information i1 output from the component mounting apparatus 1A, and outputs result information i2 indicating the determination result of whether or not the component C is present to the component mounting apparatus 1A.

[0118] According to this, before the measuring unit 48 measures the height position of the component C, the result information i2 indicating the determination result as to whether or not the component C is present in the storage unit 6a can be obtained from the server device 90A. This makes it possible to prevent problems from occurring when the component C is not present in the storage unit 6a of the tray 6. This makes it possible to prevent a decrease in productivity in the component mounting process.

[0119] The component mounting method of Example 14 includes the steps of: determining whether or not a component C is present in a storage section 6a of a tray 6 having a plurality of storage sections 6a for storing the component C; measuring the height position of the component C in the storage section 6a if the component C is present in the storage section 6a; and removing the component C from the storage section 6a and mounting it on the board 3 based on the height position of the component C.

[0120] In this way, by determining whether or not there is a component C in the storage section 6a before measuring the height position of the component C, it is possible to prevent problems from occurring when there is no component C in the storage section 6a of the tray 6. This makes it possible to prevent a decrease in productivity in the component mounting process.

[0121] The component mounting method of Example 15 includes the steps of outputting request information i1 to a server device 90A, requesting a determination as to whether or not a component C is present in a storage section 6a of a tray 6 having a plurality of storage sections 6a for storing the component C; acquiring result information i2 from the server device 90A, which indicates the determination result as to whether or not a component C is present in the storage section 6a; if the result information i2 indicates the determination result that a component C is present in the storage section 6a, measuring the height position of the component C in the storage section 6a; and, based on the height position of the component C, removing the component C from the storage section 6a and mounting it on a board 3.

[0122] In this way, by obtaining the determination result of whether or not the component C is present in the storage section 6a from the server device 90A before measuring the height position of the component C, it is possible to prevent problems from occurring when the component C is not present in the storage section 6a of the tray 6. This makes it possible to prevent a decrease in productivity in the component mounting process.
