Summary of the Invention

[0004] However, in the prior art including Patent Documents 1 and 2, since the same operation screen is displayed on a plurality of operation units, there are the following problems. That is, when an operator with a high authority level operates on one operation unit, the same authority level operation screen is also displayed on the other operation unit, so there is a problem that there is a risk that an operation not permitted to an operator with a low authority level can be performed.

[0005] Therefore, the present invention aims to provide a work device, a work system, and a work display method that enable appropriate operations corresponding to each operator from multiple operating units.

[0006] The work apparatus of the present invention comprises a work unit for performing work, a control unit for controlling the work unit, and a plurality of operation units having an input unit and a display unit, which transmit input information received from the input unit to the control unit and display information output from the control unit to the display unit. The control unit includes a specification unit for identifying which of the plurality of operation units transmitted the input information, an operator approval unit for determining whether or not to permit the operator to operate the operation unit based on authentication information relating to the operator transmitted from the operation unit identified by the specification unit, a storage unit for storing login information relating to the operator permitted by the operator approval unit in association with the operation unit identified by the specification unit, and an output processing unit for outputting display information generated based on the input information from the operation unit and the login information to the operation unit identified by the specification unit.

[0007] Another work apparatus of the present invention comprises a work unit that performs work, a control unit that controls the work unit, and a plurality of operation units having an input unit and a display unit, which transmit input information received from the input unit to the control unit and display information output from the control unit to the display unit. The control unit comprises a specification unit that identifies which of the plurality of operation units transmitted the input information, an approval request unit that, based on authentication information relating to the operator transmitted from the operation unit identified by the specification unit, sends an inquiry to an authentication server asking whether or not to allow the operator to operate the operation unit, and obtains a response from the authentication server to the inquiry, a storage unit that stores login information relating to the operator permitted by the authentication server in association with the operation unit identified by the specification unit, and an output processing unit that outputs display information generated based on the input information from the operation unit and the login information to the operation unit identified by the specification unit.

[0008] The work system of the present invention comprises the above-described work device and an operator information server that stores operator information. The control unit of the work device further includes a communication unit that transmits inquiry information based on the authentication information to the operator information server and receives the operator information from the operator information server. The operator information server receives the inquiry information transmitted from the communication unit of the work device and transmits the corresponding operator information to the communication unit. The operator approval unit determines whether or not to permit the operator to operate the operation unit based on the authentication information and the operator information corresponding to the authentication information.

[0009] Another work system of the present invention comprises the above-mentioned other work device and an authentication server. The authentication server receives the inquiry from the work device, determines whether or not to permit the operator to operate the control unit, and transmits the determination result to the work device.

[0010] The work display method of the present invention involves a control unit that controls a work unit performing work, which causes display information to be displayed on each of a plurality of operation units. The work display method includes: a identification step of identifying which of the plurality of operation units transmitted input information from which input information was transmitted; an operator approval step of determining whether or not to permit the operator to operate the operation unit based on authentication information relating to the operator transmitted from the operation unit identified in the identification step; a storage step of storing login information relating to the operator permitted in the operator approval step in association with the operation unit identified in the identification step; and an output processing step of outputting the display information generated based on the input information from the operation unit and the login information to the operation unit identified in the identification step.

[0011] According to the present invention, appropriate operations corresponding to each operator can be performed from multiple operating units. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0013] An embodiment of the present invention will be described in detail below with reference to the drawings. The configurations, shapes, etc. described below are illustrative examples for illustrative purposes and can be modified as appropriate according to the specifications of the mounting board manufacturing line, component mounting equipment, etc. In the following, corresponding elements are denoted by the same reference numerals in all drawings, and redundant explanations are omitted. In Figure 1 and some parts described later, the X-axis (vertical direction in Figure 1) in the board transport direction and the Y-axis (horizontal direction in Figure 1) perpendicular to the board transport direction are shown as two mutually orthogonal axes in the horizontal plane. In Figure 3 and some parts described later, the Z-axis (vertical direction in Figure 3) perpendicular to the horizontal plane is shown as the height direction.

[0014] First, let's explain the configuration of the mounted circuit board manufacturing line 1 with reference to Figure 1. Figure 1 schematically shows the main parts of the mounted circuit board manufacturing line 1. The mounted circuit board manufacturing line 1 is composed of multiple component mounting devices M1 to M6 connected in series, and has the function of manufacturing mounted circuit boards with components mounted on them. Each of the component mounting devices M1 to M6 has a first board transport lane L1 and a second board transport lane L2 that transport the board 2 along the X-axis from upstream (top of the page) to downstream (bottom of the page), which are located apart in the Y-axis direction. Hereinafter, in the Y-axis direction, the side where the first board transport lane L1 is located will be referred to as the front (left side of the page), and the side where the second board transport lane L2 is located will be referred to as the rear (right side of the page).

[0015] The first substrate transfer lanes L1 and the second substrate transfer lanes L2 provided in each of the component mounting devices M1 to M6 are connected to adjacent devices, and transfer the substrate 2 from upstream to downstream and deliver it to the adjacent devices. In each of the component mounting devices M1 to M6, a first component supply unit S1 is arranged in front of the first substrate transfer lane L1, and a second component supply unit S2 is arranged behind the second substrate transfer lane L2. Further, in the component mounting device M5 and the component mounting device M6, a third component supply unit S3 is arranged downstream of the first component supply unit S1, and a fourth component supply unit S4 is arranged downstream of the second component supply unit S2. A plurality of component supply units 3 for supplying components are arranged in parallel along the X-axis in the first component supply unit S1, the second component supply unit S2, the third component supply unit S3, and the fourth component supply unit S4, respectively.

[0016] In FIG. 1, each of the component mounting devices M1 to M6 includes a first component mounting head H1 that holds a component in front and mounts it on the substrate 2, a first work head moving mechanism F1 that moves the first component mounting head H1, and a first head camera C1 that moves together with the first component mounting head H1 by the first work head moving mechanism F1. Further, each of the component mounting devices M1 to M6 includes a second component mounting head H2 that holds a component behind and mounts it on the substrate, a second work head moving mechanism F2 that moves the second component mounting head H2, and a second head camera C2 that moves together with the second component mounting head H2 by the second work head moving mechanism F2.

[0017] Furthermore, the component mounting device M5 and the component mounting device M6 include a third component mounting head H3 downstream in front, a third work head moving mechanism F3 that moves the third component mounting head H3, and a third head camera C3. Also, the component mounting device M5 and the component mounting device M6 include a fourth component mounting head H4 downstream behind, a fourth work head moving mechanism F4 that moves the fourth component mounting head H4, and a fourth head camera C4.

[0018] In Figure 1, each component mounting device M1 to M6 has a first operating unit P1 positioned so that it can be operated by an operator at the front, and a second operating unit P2 positioned so that it can be operated by an operator at the rear. The first operating unit P1 and the second operating unit P2 are devices such as touch panels that include a monitor 14 (display unit) for displaying various information and screens, a touch screen 13 (input unit) for receiving input of various information, and a biometric authentication unit 15 for identifying the operator (see Figure 5).

[0019] The biometric authentication unit 15 is equipped with biometric authentication devices such as an infrared camera for capturing iris images and a fingerprint sensor, and acquires authentication information of operators logging into component mounting devices M1 to M6. In other words, each operation unit (first operation unit P1, second operation unit P2) has a biometric authentication unit 15, and authentication information is acquired by the biometric authentication unit 15.

[0020] Thus, component mounting devices M1 to M4 are 2-stage / 2-head component mounting devices, each equipped with two component supply units (first component supply unit S1, second component supply unit S2) and two mounting heads (first component mounting head H1, second component mounting head H2). Furthermore, component mounting devices M5 and M6 are 4-stage / 4-head component mounting devices, each equipped with four component supply units (first component supply unit S1, second component supply unit S2, third component supply unit S3, fourth component supply unit S4) and four mounting heads (first component mounting head H1, second component mounting head H2, third component mounting head H3, fourth component mounting head H4).

[0021] In the example shown in Figure 1, the PCB manufacturing line 1 is equipped with four 2-stage / 2-head component mounting machines M1 to M4 and two 4-stage / 4-head component mounting machines M5 and M6. However, the PCB manufacturing line 1 is not limited to this configuration. For example, the PCB manufacturing line 1 may be configured to be equipped with either one of the 2-stage / 2-head component mounting machines M1 to M4 or one of the 4-stage / 4-head component mounting machines M5 or M6.

[0022] Alternatively, the configuration may include two, three, or five or more 2-stage / 2-head component loading devices M1-M4, and three or more 4-stage / 4-head component loading devices M5 and M6. Furthermore, the arrangement order of the 2-stage / 2-head component loading devices M1-M4 and the 4-stage / 4-head component loading devices M5 and M6 can be arbitrarily set. Moreover, the component loading devices M1-M6 do not need to be physically connected.

[0023] In Figure 1, the printed circuit board manufacturing line 1 is connected to component mounting devices M1-M6 by a wired or wireless communication network and includes a server SV that sends and receives various information to and from the component mounting devices M1-M6. The server SV functions as an operator information server that stores operator information of operators performing work on the component mounting devices M1-M6. The server SV also functions as an authentication server that determines whether or not to allow operations by an operator attempting to log in from the control unit, based on requests from the component mounting devices M1-M6.

[0024] Next, with reference to Figures 2 and 3, the detailed configuration of the 2-stage / 2-head component loading devices M1 to M4 will be described. At the top center of the base 4, the first substrate transport lane L1 is located in front, and the second substrate transport lane L2 is located behind. The first substrate transport lane L1 is equipped with a pair of first substrate transport conveyors K1 that transport the substrate 2 to the loading work position. The first substrate transport lane L1 positions and holds the transported substrate 2 at the loading work position. The second substrate transport lane L2 is equipped with a pair of second substrate transport conveyors K2 that transport the substrate 2 to the loading work position. The second substrate transport lane L2 positions and holds the transported substrate 2 at the loading work position. Thus, the component loading devices M1 to M4 are equipped with multiple (two) substrate transport lanes (first substrate transport lane L1, second substrate transport lane L2) for transporting and positioning the substrate 2.

[0025] A first component supply unit S1 is located in front of the first substrate transport lane L1, and a second component supply unit S2 is located behind the second substrate transport lane L2. Both the first component supply unit S1 and the second component supply unit S2 are equipped with trolleys 5 on which multiple component supply units 3 (tape feeders) are pre-mounted. The trolleys 5 hold reels 7 that store carrier tapes 6 holding components in a wound state. The carrier tape 6 pulled out from the reels 7 is fed by the component supply units 3, and the components held by the carrier tape 6 are supplied to the component supply positions. Thus, component mounting devices M1 to M4 are equipped with multiple (two) component supply units (first component supply unit S1, second component supply unit S2) for supplying components.

[0026] In Figures 2 and 3, a Y-axis table 8 is positioned upstream and a Y-axis support 9 is positioned downstream at both ends of the X-axis on the upper surface of the base 4. Guide sections 10 extending along the Y-axis are positioned opposite each other on the Y-axis table 8 and the Y-axis support 9. A Y-axis linear motor 11 extending along the Y-axis is also positioned on the Y-axis table 8. Between the Y-axis table 8 and the Y-axis support 9, a first beam B1 is positioned in front and a second beam B2 is positioned behind. The first beam B1 and the second beam B2 are driven by the Y-axis linear motor 11 to move back and forth along the guide section 10.

[0027] A first linear motor D1 extending along the X-axis is positioned on the first beam B1. A first moving member E1, driven by the first linear motor D1 and moving left and right along the X-axis, is coupled to the first beam B1. A first component mounting head H1 and a first head camera C1 are mounted on the first moving member E1. A second linear motor D2 extending along the X-axis is positioned on the second beam B2. A second moving member E2, driven by the second linear motor D2 and moving left and right along the X-axis, is coupled to the second beam B2. A second component mounting head H2 and a second head camera C2 are mounted on the second moving member E2.

[0028] In Figure 3, the first component mounting head H1 and the second component mounting head H2 are equipped with multiple component holding nozzles 12 at their lower ends for holding components. The first component mounting head H1 and the second component mounting head H2 raise and lower the component holding nozzles 12 along the Z-axis and rotate them around the Z-axis.

[0029] In Figures 2 and 3, the first component mounting head H1 moves horizontally (in the X-axis and Y-axis directions) by the Y-axis linear motor 11 and the first linear motor D1. That is, the Y-axis table 8 and the first beam B1 constitute the first work head movement mechanism F1 that moves the first component mounting head H1 and the first head camera C1. The second component mounting head H2 moves horizontally by the Y-axis linear motor 11 and the second linear motor D2. That is, the Y-axis table 8 and the second beam B2 constitute the second work head movement mechanism F2 that moves the second component mounting head H2 and the second head camera C2.

[0030] The first component mounting head H1 and the first work head movement mechanism F1 constitute a first work unit W1 that performs tasks including component mounting, such as receiving components from the first component supply unit S1 and mounting them onto a substrate 2 positioned in the first substrate transport lane L1 or the second substrate transport lane L2. The second component mounting head H2 and the second work head movement mechanism F2 constitute a second work unit W2 that performs tasks including component mounting, such as receiving components from the second component supply unit S2 and mounting them onto a substrate 2 positioned in the second substrate transport lane L2 or the first substrate transport lane L1.

[0031] Thus, the component mounting devices M1 to M4 are equipped with multiple work units (first work unit W1, second work unit W2) that receive components from component supply units (first component supply unit S1, second component supply unit S2) and perform tasks including component mounting, which involves mounting the received components onto the circuit board 2.

[0032] In Figures 2 and 3, the first head camera C1 and the second head camera C2 move above the substrate 2 held at the mounting position on the first substrate transport lane L1 or the second substrate transport lane L2, and capture images of the substrate marks (not shown) provided on the substrate 2. The image results are recognized by image recognition to determine the position of the substrate 2.

[0033] On the upper surface of the base 4, a first component camera G1, which captures images upwards, is positioned between the first component supply unit S1 and the first substrate transport lane L1. A second component camera G2, which captures images upwards, is positioned between the second component supply unit S2 and the second substrate transport lane L2. When the first component mounting head H1, which has taken a component from the first component supply unit S1, moves above the first component camera G1, the first component camera G1 captures images of the component held by the component holding nozzle 12. When the second component mounting head H2, which has taken a component from the second component supply unit S2, moves above the second component camera G2, the second component camera G2 captures images of the component held by the component holding nozzle 12. The imaging results are recognized by image recognition to determine the orientation of the component held by the component holding nozzle 12.

[0034] During the component mounting operation on circuit board 2 by the first component mounting head H1, the component mounting position is corrected by taking into account the circuit board position recognition result by the first head camera C1 and the component recognition result by the first component camera G1. Similarly, during the component mounting operation on circuit board 2 by the second component mounting head H2, the component mounting position is corrected by taking into account the circuit board position recognition result by the second head camera C2 and the component recognition result by the second component camera G2.

[0035] In Figures 2 and 3, the first operation unit P1 is located at the front upper part of the component mounting devices M1 to M4, and the second operation unit P2 is located at the rear upper part. The control unit 20 is located on the base 4. The control unit 20 is connected to the first operation unit P1, the second operation unit P2, and various parts of the component mounting devices M1 to M4 (see Figure 5). As a result, the multiple operation units (first operation unit P1 and second operation unit P2), which have an input unit (touchscreen 13), a display unit (monitor 14), and a biometric authentication unit 15, can communicate with the control unit 20. That is, the multiple operation units transmit input information received from the input unit to the control unit 20, and display information output from the control unit 20 is displayed on the display unit. Thus, the component mounting devices M1 to M4 are equipped with multiple operation units (first operation unit P1, second operation unit P2) connected to the control unit 20.

[0036] The control unit 20 controls the component supply unit 3 of the first work unit W1 and the first component supply unit S1 to perform component mounting operations, which involve mounting components onto the substrate 2 held at the mounting work position on the first substrate transport lane L1 or the mounting work position on the second substrate transport lane L2. The control unit 20 also controls the component supply unit 3 of the second work unit W2 and the second component supply unit S2 to perform component mounting operations, which involve mounting components onto the substrate 2 held at the mounting work position on the second substrate transport lane L2 or the mounting work position on the first substrate transport lane L1. The control unit 20 performs component mounting operations using multiple mounting modes according to the production program 34 (Figure 5) stored in the memory unit 27 of the control unit 20.

[0037] Here, with reference to Figure 4, the independent mounting mode and the alternating mounting mode, which are among the mounting modes controlled by the control unit 20, will be explained. Figure 4(a) schematically shows the component mounting operation in the independent mounting mode in component mounting devices M1 to M4. In the independent mounting mode, the first component mounting head H1 receives components from the component supply unit 3 attached to the first component supply unit S1 and mounts them onto the first substrate 2F that has been transported into the first substrate transport lane L1 (arrow a1). Similarly, in the independent mounting mode, the second component mounting head H2 receives components from the component supply unit 3 attached to the second component supply unit S2 and mounts them onto the second substrate 2R that has been transported into the second substrate transport lane L2 (arrow a2).

[0038] Specifically, the control unit 20 controls the first substrate 2F positioned in the first substrate transport lane L1 of the multiple substrate transport lanes, by having only the first work unit W1 of the multiple work units receive components from the first component supply unit S1 of the multiple component supply units and mount them. Similarly, the control unit 20 controls the second substrate 2R positioned in the second substrate transport lane L2 of the multiple substrate transport lanes, by having only the second work unit W2 of the multiple work units receive components from the second component supply unit S2 of the multiple component supply units and mount them.

[0039] Figure 4(b) schematically shows the component mounting operation in alternating mounting mode in component mounting devices M1 to M4. In alternating mounting mode, the operation of the first component mounting head H1 receiving and mounting components from the first component supply unit S1 (arrow b1) and the operation of the second component mounting head H2 receiving and mounting components from the second component supply unit S2 (arrow b2) are performed alternately on at least one of the first board 2F or the second board 2R. That is, the control unit 20 causes components to be mounted on the first board 2F not only by the first work unit W1 but also by the second work unit W2. Similarly, the control unit 20 causes components to be mounted on the second board 2R not only by the second work unit W2 but also by the first work unit W1.

[0040] In non-independent mounting modes, such as alternating mounting mode, the areas in which the first component mounting head H1 moves and the areas in which the second component mounting head H2 moves overlap during component mounting. Therefore, in non-independent mounting mode, the control unit 20 controls the first work unit W1 and the second work unit W2 so that the first component mounting head H1 and the second component mounting head H2 do not interfere with each other. On the other hand, in independent mounting mode, the areas in which the first component mounting head H1 moves and the areas in which the second component mounting head H2 moves do not overlap during component mounting. Therefore, in independent mounting mode, the control unit 20 controls the first work unit W1 and the second work unit W2 without considering interference between the first component mounting head H1 and the second component mounting head H2.

[0041] As described above, the component mounting devices M1 to M4 include a plurality of substrate transport lanes (first substrate transport lane L1, second substrate transport lane L2) for transporting and positioning the substrate 2, a plurality of component supply units (first component supply unit S1, second component supply unit S2) for supplying components, a plurality of work units (first work unit W1, second work unit W2) for receiving components from the component supply units and performing work including component mounting, which involves mounting the received components onto the substrate 2, a control unit 20 for controlling the plurality of work units in independent mounting mode or non-independent mounting mode, and a plurality of operation units (first operation unit P1, second operation unit P2) connected to the control unit 20.

[0042] Next, with reference to Figure 1, the detailed configuration of the 4-stage / 4-head component loading devices M5 and M6 will be described. Component loading devices M5 and M6 are similar to the 2-stage / 2-head component loading devices M1 to M4 described above in that they are equipped with a first work section W1 and a second work section W2 upstream. However, component loading devices M5 and M6 differ from M1 to M4 in that they are further equipped with a third work section W3 downstream and a fourth work section W4 downstream. Furthermore, component loading devices M5 and M6 differ from M1 to M4 in that the first operating section P1 is located between the first work section W1 and the third work section W3, and the second operating section P2 is located between the second work section W2 and the fourth work section W4. Hereafter, the same reference numerals are used for parts identical to those in component loading devices M1 to M4, and detailed explanations will be omitted.

[0043] In Figure 1, the third component mounting head H3 and the third work head movement mechanism F3 constitute a third work unit W3 that receives components from the third component supply unit S3 and performs tasks including component mounting, which involves mounting the components onto a substrate 2 positioned in the movement area of ​​the third component mounting head H3 in either the first substrate transport lane L1 or the second substrate transport lane L2. Furthermore, the fourth component mounting head H4 and the fourth work head movement mechanism F4 constitute a fourth work unit W4 that receives components from the fourth component supply unit S4 and performs tasks including component mounting, which involves mounting the components onto a substrate 2 positioned in the movement area of ​​the fourth component mounting head H4 in either the first substrate transport lane L1 or the second substrate transport lane L2.

[0044] In independent mounting mode, the control unit 20 ensures that only the third work unit W3 receives components from the third component supply unit S3 and mounts them onto a substrate 2 positioned in the movement area of ​​the third component mounting head H3 in the first substrate transport lane L1. Also in independent mounting mode, the control unit 20 ensures that only the fourth work unit W4 receives components from the fourth component supply unit S4 and mounts them onto a substrate 2 positioned in the movement area of ​​the fourth component mounting head H4 in the second substrate transport lane L2.

[0045] In non-independent mounting mode, the control unit 20 causes components to be mounted not only in the third work unit W3 but also in the fourth work unit W4 on the substrate 2 positioned in the movement area of ​​the third component mounting head H3 in the first substrate transport lane L1. Also in non-independent mounting mode, the control unit 20 causes components to be mounted not only in the fourth work unit W4 but also in the third work unit W3 on the substrate 2 positioned in the movement area of ​​the fourth component mounting head H4 in the second substrate transport lane L2.

[0046] As described above, the component mounting devices M5 and M6 include a plurality of substrate transport lanes (first substrate transport lane L1, second substrate transport lane L2) for transporting and positioning the substrate 2, a plurality of component supply units (first component supply unit S1, second component supply unit S2, third component supply unit S3, fourth component supply unit S4) for supplying components, a plurality of work units (first work unit W1, second work unit W2, third work unit W3, fourth work unit W4) for receiving components from the component supply units and performing work including component mounting, which involves mounting the received components onto the substrate 2, a control unit 20 for controlling the plurality of work units in independent mounting mode or non-independent mounting mode, and a plurality of operation units (first operation unit P1, second operation unit P2) connected to the control unit 20.

[0047] Next, referring to Figure 5, the configuration of the control systems for the 2-stage / 2-head component mounting devices M1 to M4 will be explained, focusing on the functions that appropriately process operations in response to operators operating multiple control units (first control unit P1, second control unit P2) and functions that appropriately process operations in response to the mounting modes of multiple work units (first work unit W1, second work unit W2).

[0048] The control unit 20 in component mounting devices M1 to M4 includes an input processing unit 21, a processing unit 22, an operator approval unit 23, an exclusive control unit 24, an output processing unit 25, a communication unit 26, and a storage unit 27. The communication unit 26 transmits and receives various information to and from the server SV and other work devices (component mounting devices M1 to M6) via a wired or wireless communication network. The input processing unit 21 receives input information from multiple operation units (first operation unit P1, second operation unit P2), identifies which operation unit the input came from, and outputs a command based on the input information. The input processing unit 21 includes an internal processing unit 28, an identification unit 29, and an output unit 30.

[0049] In Figure 5, the processing unit 22 executes various processes described later based on instructions, and causes the work units (first work unit W1, second work unit W2) to perform tasks such as component mounting. The processing unit 22 includes a component mounting processing unit 31, a one-sided operation processing unit 32, and a two-sided operation processing unit 33 as internal processing units. The storage unit 27 is a memory device that stores production programs 34, login information 35, device status data 36, ​​etc.

[0050] The production program 34 stores information and control programs necessary for component mounting work, such as the size of the board 2, the type and mounting position (XY coordinates) of the components to be mounted, the arrangement of components in the component supply unit (first component supply unit S1, second component supply unit S2), and the mounting mode during component mounting (independent mounting mode, alternating mounting mode), for each type of mounted board.

[0051] In Figure 5, the processing unit 22 sequentially acquires information such as the status of the work units (first work unit W1, second work unit W2), the progress of the component mounting work, the progress of calibration and supply position teaching, and information of the operation units (first operation unit P1, second operation unit P2) that performed operations on the control unit 20, and stores this information in the storage unit 27 as device status data 36. The component mounting processing unit 31 controls the first work unit W1 and the second work unit W2 based on the production program 34 and the device status data 36, ​​and executes the transport of the substrate 2 and the component mounting work of mounting components onto the substrate 2.

[0052] The first operation unit P1 is connected to the first connection port T1 provided on the control unit 20. The second operation unit P2 is connected to the second connection port T2 provided on the control unit 20. Input information, including operation events that represent the content of the operation performed by the operator on the touchscreen 13 (input unit) and coordinate data indicating the location where the operation was performed, is transmitted to the input processing unit 21 of the control unit 20 via the connection ports (first connection port T1, second connection port T2). Examples of operation events include taps, long taps, flicks, slides, pen up, pen down, pitch in, and pitch out.

[0053] In Figure 5, the receiving unit 28 receives input information (operation events, coordinate data) output from the touchscreen 13 and authentication information acquired by the biometric authentication unit 15. The input processing unit 21 determines the command entered by the operator on the touchscreen 13 based on the input information received by the receiving unit 28. The identification unit 29 determines which of the operation units the input information transmitted from the operation units (first operation unit P1, second operation unit P2) to the control unit 20 was input from, based on the connection ports (first connection port T1, second connection port T2) through which the input information passes. The output unit 30 associates the identified command and received authentication information with the identified connection port information and outputs it to the processing unit 22, the operator approval unit 23, and the output processing unit 25.

[0054] The operator approval unit 23 determines whether or not to permit the operator to operate the operation unit based on the authentication information about the operator transmitted from the operation unit (first operation unit P1, second operation unit P2) and the operator information corresponding to the authentication information. In this embodiment, the operator information is stored as a database in the server SV of the mounting board manufacturing line 1 (work system). That is, the server SV is an operator information server that stores operator information for each operator performing work on component mounting devices M1 to M6 in the mounting board manufacturing line 1, including information that identifies the operator (such as an ID number), proficiency level, and biometric authentication data used in the operator authentication process.

[0055] Specifically, the operator approval unit 23 transmits inquiry information based on authentication information to the server SV via the communication unit 26. The server SV (operator information server) receives the inquiry information transmitted from the communication unit 26 of the work device (part mounting device M1~M6) and transmits (replies to) the corresponding operator information to the communication unit 26 of that work device. The operator approval unit 23 then receives the operator information from the server SV via the communication unit 26 and determines whether to grant or deny permission to the operator based on the authentication information and the operator information. In this way, the communication unit 26 transmits inquiry information based on authentication information to the server SV and receives operator information from the server SV. Note that the work system may also be configured such that the storage unit 27 of the work device stores the operator information, in addition to the configuration in which the operator information is obtained from the server SV.

[0056] In Figure 5, when the operator approval unit 23 authorizes an operator to perform an operation, it creates login information, which is information about the authorized operator. The operator approval unit 23 then associates the login information with the information of the operation unit identified as having transmitted the authentication information and stores it in the storage unit 27 as login information 35. In other words, the storage unit 27 stores the login information 35, which is information about the operator authorized by the operator approval unit 23, in association with the operation unit identified by the identification unit 29 as having transmitted the authentication information. Furthermore, if the operation unit is not operated by the authorized operator within a predetermined time (for example, 1 minute), the operator approval unit 23 deletes the login information 35 related to that operator from the storage unit 27. As a result, the operator is automatically logged out of the authorized operation unit.

[0057] The output processing unit 25 outputs the display information generated based on the input information from the operation units (first operation unit P1, second operation unit P2) and the login information 35 to the operation unit identified by the identification unit. The operation unit that receives the display information displays it on the monitor 14 (display unit). As a result, the monitor 14 operated by an authorized operator displays display information such as the operation screen corresponding to the operator and implementation mode.

[0058] Next, following the flowcharts in Figures 6 and 7, and referring to Figure 8, we will explain a work display method that causes the monitor 14 (display unit) of each operation unit to display information corresponding to the authentication information transmitted from multiple operation units (first operation unit P1, second operation unit P2) to the operation unit. Here, we will explain using an example in which an operator operates the operation unit of the component mounting device M1.

[0059] In Figure 6, when an operator touches the touchscreen 13 of any of the control units, input information is transmitted from that control unit, and the input processing unit 21 receives the input information via the connection ports (first connection port T1, second connection port T2) (ST1: Input Information Reception Process). Next, the identification unit 29 identifies which of the multiple control units the input information transmitted from the control unit was input from, based on the connection port through which the input information passed (ST2: Identification Process). Next, the operator approval unit 23 checks whether the login information 35 corresponding to the identified control unit is stored in the storage unit 27 (ST3: Login Information Reference Process).

[0060] Next, the operator approval unit 23 determines whether the identified operation unit is logged in or not (ST4: Login Determination Step). Specifically, the operator approval unit 23 determines that the user is logged in (logged in) if the login information 35 corresponding to the identified operation unit is stored in the storage unit 27, and determines that the user is not logged in (logged off) if the information is not stored. Hereafter, the identified operation unit will be described as the front first operation unit P1. If the identified first operation unit P1 is determined to be in a logged off state (No in ST4), the login process is executed (ST5: First Login Process Step).

[0061] In Figure 7, in the first login processing step (first login processing method), the output processing unit 25 first outputs an authentication information input screen to the first operation unit P1 based on a command from the operator approval unit 23 (ST11: Authentication Information Input Screen Output Step). As a result, the authentication information input screen (not shown) is displayed on the monitor 14 (display unit) of the first operation unit P1. The authentication information input screen displays instructions to the operator to perform an authentication operation using the sensor of the biometric authentication unit 15. For example, the monitor 14 may display a message prompting the operator to perform an authentication operation, such as "Please take an image of the iris using the infrared camera" or "Please acquire a fingerprint using the fingerprint sensor."

[0062] Furthermore, the identification of the operator by the operator approval unit 23 is not limited to using authentication information obtained by the biometric authentication unit 15. For example, the operator may be identified using the user ID and password entered by the operator on the touchscreen 13 of the control unit.

[0063] In Figure 7, the operator authentication information obtained by the biometric authentication unit 15 of the first operation unit P1 is received by the receiving unit 28 via the first connection port T1 (ST12: Authentication information reception step). When the authentication information concerning the operator transmitted from the first operation unit P1 (operation unit) is received (Yes in ST12), the operator approval unit 23 queries the server SV (operator information server) for operator information corresponding to the authentication information and obtains (references) the operator information (ST13: Operator information reference step).

[0064] Next, the operator approval unit 23 determines whether or not to permit the operator operating the first operation unit P1 to operate it, based on the authentication information and operator information (ST14: Operator Approval Process). In other words, in the operator approval process (ST14), a decision is made on whether or not to permit the operator to operate the operation unit, based on the authentication information about the operator transmitted from the operation unit.

[0065] In Figure 7, if permission is granted (Yes in ST14), the operator approval unit 23 creates login information 35 for the authorized operator and stores it in the storage unit 27 in association with the identified operation unit (first operation unit P1) (ST15: storage process). That is, in the storage process (ST15), the login information 35, which is information about the operator authorized in the operator approval process (ST14), is stored in association with the operation unit identified in the identification process (ST2) as having transmitted the authentication information. Next, the output processing unit 25 outputs the login completion screen as display information to the first operation unit P1 (ST16: login completion screen output process). As a result, the monitor 14 (display unit) of the first operation unit P1 displays a message indicating that login has been completed (login completion screen).

[0066] If permission is denied (No in ST14), the operator approval unit 23 does not create login information 35 for the operator, and the output processing unit 25 outputs a login failure screen as display information to the first operation unit P1 (ST17: Login Failure Screen Output Process). As a result, the monitor 14 (display unit) of the first operation unit P1 displays a message indicating that the login failed (Login Failure Screen). After that, the process returns to the input information reception process (ST1) and waits for an operation on the touchscreen 13 (input unit) of the first operation unit P1.

[0067] In Figure 6, after login is completed in the first login processing step (ST5), input information entered by the operator from the touchscreen 13 (input unit) of the first operation unit P1 is received by the input processing unit 21 (ST6: input information reception step). Next, display information is generated based on the input information and login information 35 (ST7: display information generation step). If it is determined that the user is logged in (Yes) in the login determination step (ST4), the display information generation step (ST7) generates display information based on the input information received in the input information reception step (ST1). Next, the output processing unit 25 outputs the generated display information to the first operation unit P1 (ST8: output processing step). As a result, the display information is displayed on the monitor 14 (display unit) of the first operation unit P1.

[0068] In other words, in the output processing step (ST8), the output processing unit 25 outputs the display information generated based on the input information received from the operation unit in the input information receiving step (ST1 or ST6) and the login information 35 to the operation unit identified in the identification step (ST2). After that, it returns to the input information receiving step (ST1) and waits for operation on the touchscreen 13 (input unit) of the first operation unit P1. If the first operation unit P1 is not operated within a predetermined time (for example, 1 minute), the operator approval unit 23 deletes the login information 35 (automatic logout process).

[0069] Here, with reference to Figure 8(a), an example of the operation screen 40 (first display information) displayed on the monitor 14 of the first operation unit P1 by the output processing step (ST8) will be described. The operation screen 40 is provided with an operator name display field 41, a work selection field 42, and a work details display field 43. The operator name display field 41 displays information that identifies the operator authorized in the first login processing step (ST5) (here, "OP1"). The operator name display field 41 is also provided with a change button 41a. When the change button 41a is operated, the login screen is displayed. For example, if the operator name is that of a different operator who was previously operated, the new operator operates the change button 41a and logs in with their own login name.

[0070] The task selection field 42 displays buttons for performing tasks permitted to the operator, based on the operator's proficiency level included in the operator information. Operator OP1 is a highly skilled operator with a "high" proficiency level, and the task selection field 42 displays the task A selection button 42a, the task B selection button 42b, and the task C selection button 42c. The task details display field 43 displays detailed information about the task selected in the task selection field 42.

[0071] In this example, the Task A selection button 42a is selected, and the task details display area 43 shows detailed information for performing "Task A". That is, the receiving unit 28 receives input information from operator OP1 operating the touchscreen 13 of the first operation unit P1, the output processing unit 25 transmits detailed information (display information) regarding "Task A" of the component mounting device M1, and the transmitted detailed information is displayed on the monitor 14 of the first operation unit P1.

[0072] In Figure 8(a), the device status display frame 44 is displayed in the work details display area 43. The device status display frame 44 displays the status of the two tables (first parts supply unit S1 and second parts supply unit S2) of the parts loading device M1, one above the other. In the device status display frame 44, the table in front of the operator operating the control unit is displayed in the lower section, and the table on the opposite side of the operator is displayed in the upper section. That is, on the monitor 14 of the first control unit P1, the status of the front table F (preparation in progress) is displayed in the lower section, and the status of the rear table R (preparation in progress) is displayed in the upper section.

[0073] Here, with reference to Figure 8(b), another example of the operation screen 45 (first display information) displayed on the monitor 14 by the output processing step (ST8) will be described. Figure 8(b) shows the operation screen 45 displayed on the monitor 14 after operator OP2, who has a skill level of "medium," logs in from the second operation unit P2. The operation screen 45, like the operation screen 40 in Figure 8(a), is provided with an operator name display field 46 with a change button 46a, a work selection field 47, and a work details display field 48. In the device status display frame 49 displayed in the work details display field 48, the status of the rear table R (preparation in progress) is displayed in the lower field, and the status of the front table F (preparation in progress) is displayed in the upper field.

[0074] In the task selection field 47, the Task A selection button 47a and Task B selection button 47b are displayed based on the operator's proficiency level included in the operator information. In other words, the Task C selection button 42c, which allows operators with a "high" proficiency level to select Task C but not operators with a "medium" proficiency level to select Task C, is not displayed.

[0075] In Figure 8(b), the work details display area 48 shows detailed information about "Work A" selected in the work selection area 47. Among the operation items for "Work A" displayed in the work details display area 48, there are items that are not permitted for operators with a proficiency level of "medium". If operator OP2 selects an operation item that is not permitted, a warning display frame 48a will be displayed in the work details display area 48, warning that it is an "unauthorized operation", and operation acceptance in the work details display area 48 will be suspended. Operation acceptance in the work details display area 48 will be resumed when operator OP2 operates the confirmation button 48b provided in the warning display frame 48a.

[0076] When operator OP1 logs into the front first control unit P1 and operator OP2 logs into the rear second control unit P2 of the component loading device M1 at the same time, the front monitor 14 displays the operation screen 40 and the rear monitor 14 displays the operation screen 45. At this time, operator OP1 can operate the component loading device M1 separately from the first control unit P1, and operator OP2 can operate it separately from the second control unit P2. However, each control unit will not accept operations other than those corresponding to the operator's proficiency level, thus preventing operator OP2, who has less proficiency, from mistakenly performing unauthorized operations.

[0077] In this manner, the output processing unit 25 outputs different first display information (operation screen 40, operation screen 45) to each operation unit (first operation unit P1, second operation unit P2) based on the authentication information input from each operation unit. The output processing unit 25 also outputs first display information, including operation items permitted to the operator based on the login information 35, to the specified operation unit, and the operation unit transmits the input information entered from the touchscreen 13 (input unit) regarding the operation items to the control unit 20. Furthermore, the output processing unit 25 outputs first display information based on the operator's proficiency level (high, medium, low, etc.) corresponding to the login information 35 to the specified operation unit (first operation unit P1, second operation unit P2).

[0078] As described above, the component mounting devices M1 to M6 of this embodiment are work devices (work systems) comprising: work units (first work unit W1, second work unit W2, third work unit W3, fourth work unit W4) for performing work; a control unit 20 for controlling the work units; and a plurality of operation units (first operation unit P1, second operation unit P2) having an input unit (touch screen 13) and a display unit (monitor 14) that transmit input information received from the input unit to the control unit 20 and display information (operation screen 40, operation screen 45, operation screen 50) output from the control unit 20 to the display unit.

[0079] The control unit 20 includes an identification unit 29 that identifies which of the multiple operation units the input information transmitted from the operation unit to the control unit 20 originated from; an operator approval unit 23 that determines whether or not to allow the operator to operate the operation unit based on authentication information about the operator transmitted from one of the operation units; a storage unit 27 that stores login information 35, which is information about the operator approved by the operator approval unit 23, in association with the operation unit identified by the identification unit 29 as having transmitted the authentication information; and a storage unit 27 that stores display information generated based on the input information from the operation unit and the login information 35 to the operation unit identified by the identification unit 29. Output It includes an output processing unit 25. This allows for appropriate operations corresponding to each operator to be performed from multiple operating units (first operating unit P1, second operating unit P2).

[0080] Next, with reference to Figures 9 and 10, the configuration of the control system for another embodiment of the 2-stage / 2-head component mounting device (hereinafter simply referred to as "component mounting device M1A to M4A") and the configuration of the control system for another embodiment of the server (hereinafter simply referred to as "server SV1") will be described. In other words, the mounting board manufacturing line of the other embodiment is equipped with work equipment (component mounting devices M1A to M4A) and server SV1 (authentication server).

[0081] The control unit 20A of component mounting devices M1A to M4A differs from component mounting devices M1 to M4 and server SV in that it includes an approval request unit 37, and the server SV1 performs the determination of whether or not to authorize the operator's operation based on authentication information. In other words, server SV1 is an authentication server that receives inquiries from the work device (component mounting devices M1A to M4A), determines whether or not to authorize the operator to operate the control unit, and transmits the determination result to the work device. Hereafter, the same reference numerals are used for components mounting devices M1 to M4 and server SV, and detailed explanations are omitted.

[0082] In Figure 9, the authorization request unit 37 queries the server SV1 (authentication server) via the communication unit 26 to determine whether or not to allow the operator to operate the operation unit, based on the authentication information about the operator transmitted from the operation unit (first operation unit P1, second operation unit P2). The authorization request unit 37 also obtains the decision result from the server SV1 via the communication unit 26. Furthermore, the authorization request unit 37 creates login information, which is information about the operator authorized by the server SV1, associates the login information with the information of the operation unit identified as having transmitted the authentication information, and stores it in the storage unit 27A as login information 35A.

[0083] In other words, the storage unit 27A stores login information 35A, which is information about operators authorized by the server SV1 (authentication server), in association with the operation units (first operation unit P1, second operation unit P2) identified by the identification unit 29 as having transmitted the authentication information. Furthermore, if an operation unit is not operated by an authorized operator within a predetermined time (for example, 1 minute), the authorization request unit 37 deletes the login information 35A related to that operator from the storage unit 27A. As a result, that operator is automatically logged out of the authorized operation unit.

[0084] In Figure 10, the authentication processing unit 70 of the server SV1 comprises a reception unit 71, an operator identification processing unit 72, an authentication communication unit 73, and an authentication storage unit 74. The authentication communication unit 73 transmits and receives various information to and from the work equipment (component mounting devices M1A to M4A) via a wired or wireless communication network. The authentication storage unit 74 is a storage device that stores operator information 75, etc. The operator information 75 stores information that identifies the operator (such as an ID number), their proficiency level, and biometric authentication data used in the operator identification process for each operator performing work on component mounting devices M1A to M4A in the printed circuit board manufacturing line.

[0085] The reception unit 71 receives operator authentication requests transmitted from the work devices (part mounting devices M1A to M4A) via the authentication communication unit 73. The authentication requests transmitted from the work devices include authentication information about the operator transmitted from the operation unit. The operator identification processing unit 72 identifies (identifies) an operator that matches the authentication information based on the authentication information included in the received authentication request and the operator information 75 stored in the authentication storage unit 74. Specifically, it searches for a matching operator by comparing the authentication information included in the authentication request with the biometric authentication data of multiple operators included in the operator information 75.

[0086] If the operator identification processing unit 72 finds a matching operator, it sends (replies) to the work device that sent the authentication request via the authentication communication unit 73, indicating that the operator in question is permitted to perform the authentication, along with information identifying the operator and their proficiency level. If the operator identification processing unit 72 does not find a matching operator, it sends (replies) to the work device that sent the authentication request via the authentication communication unit 73, indicating that the operator in question is not permitted to perform the authentication.

[0087] Next, following the flow charts in Figures 6 and 11, another embodiment of the work display method in a mounting board manufacturing line (work system) equipped with component mounting devices M1A to M4A and server SV1 will be described. In this other embodiment of the work display method, the login process executed when the login determination step (ST4) determines that the system is logged off (No) is the second login process, which differs from the work display method shown in Figures 7 and 8, where the first login process is ST5. The second login process will be described below.

[0088] In Figure 11, the second login processing step (second login processing method) first executes the authentication information input screen output step (ST11) and the authentication information reception step (ST12). When authentication information concerning the operator transmitted from the operation unit is received (Yes in ST12), the approval request unit 37 sends an authentication request to the server SV1 (authentication server) and inquires whether permission is granted or denied (ST21: approval request step). Next, the approval request unit 37 obtains the result of the permission / denial decision from the server SV1 (ST22: result acquisition step). If the permission / denial decision result is permission (Yes in ST23), the storage step (ST15) and the login completion screen output step (ST16) are executed. If the permission / denial decision result is denial (No in ST23), the login failure screen output step (ST17) is executed.

[0089] Next, with reference to Figures 4, 5, 12, and 13, the control of the control unit 20 in various mounting modes of the 2-stage / 2-head component mounting devices M1 to M4 will be described. Based on the mounting mode during component mounting included in the production program 34, the control unit 20 controls the substrate transport conveyors (first substrate transport conveyor K1, second substrate transport conveyor K2), component supply units (first component supply unit S1, second component supply unit S2), work units (first work unit W1, second work unit W2), etc.

[0090] First, let's explain the control by the control unit 20 in the independent mounting mode. In independent mounting mode, the area in which the first component mounting head H1 moves and the area in which the second component mounting head H2 moves do not overlap during component mounting (see Figure 4(a)). Therefore, in independent mounting mode, multiple operating units (first operating unit P1, second operating unit P2) can individually operate the first work unit W1 or the second work unit W2 at the same time.

[0091] Here, with reference to Figure 12, an example of the operation screen displayed on the monitor 14 of the first operation unit P1 during component mounting work in independent mounting mode will be described. In Figure 12(a), the operation screen 55 is provided with an operator name display field 56, a work selection field 57, and a work details display field 58. The work selection field 57 is provided with a work D selection button 57d for selecting "Work D," which is a work performed by operator OP1 during component mounting work, and a work E selection button 57e for selecting "Work E." The work details display field 58 displays detailed information of "Work D," which was selected by operating the work D selection button 57d in the work selection field 57.

[0092] In Figure 12(a), the work details display area 58 is provided with an operation mode selection frame 59 and a table selection frame 60. The operation mode selection frame 59 is provided with radio buttons for selecting a double-sided operation mode and a single-sided operation mode. In this example, the double-sided operation mode is selected. When the double-sided operation mode is selected in the first operation unit P1, processing by the double-sided operation processing unit 33 of the processing unit 22 is executed on the first operation unit P1 and the second operation unit P2. That is, the double-sided operation processing unit 33 controls the first operation unit P1 to accept only operations on the first substrate transport lane L1 and the first work unit W1, and the second operation unit P2 to accept only operations on the second substrate transport lane L2 and the second work unit W2.

[0093] Specifically, the dual-sided operation processing unit 33 sets the front table selection button 60a and the rear table selection button 60b of the table selection frame 60 on the operation screen 55 displayed on the monitor 14 of the front first operation unit P1 to be unselectable. The dual-sided operation processing unit 33 then displays the operation items for the first substrate transport lane L1 and the first work unit W1 on the monitor 14 of the front first operation unit P1, and controls the touchscreen 13 of the front first operation unit P1 to accept only operations for the first substrate transport lane L1 and the first work unit W1.

[0094] Similarly, the dual-sided operation processing unit 33 sets the front table selection button and the rear table selection button on the table selection frame of the operation screen (not shown) displayed on the monitor 14 of the rear second operation unit P2 to be unselectable. The dual-sided operation processing unit 33 then displays the operation items for the second substrate transport lane L2 and the second work unit W2 on the monitor 14 of the rear second operation unit P2, and controls the touchscreen 13 of the rear second operation unit P2 to accept only operations for the second substrate transport lane L2 and the second work unit W2. As a result, in dual-sided operation mode, for example, operator OP1 can perform error handling for the front table at the front first operation unit P1, while simultaneously another operator can perform production monitoring operations for the rear table at the rear second operation unit P2.

[0095] Figure 12(b) shows an example in which the one-sided operation mode is selected in the operation mode selection frame 63 provided in the work details display section 62 of the operation screen 61. When the one-sided operation mode is selected in the first operation unit P1, processing by the one-sided operation processing unit 32 of the processing unit 22 is executed on the first operation unit P1 and the second operation unit P2, and the one-sided operation processing unit 32 controls the system to accept only operations from the first operation unit P1 and not operations from the second operation unit P2. In other words, the one-sided operation processing unit 32 controls only the operation unit in which the one-sided operation mode is selected among the multiple operation units (first operation unit P1, second operation unit P2) to operate on multiple substrate transport lanes (first substrate transport lane L1, second substrate transport lane L2) and multiple work units (first work unit W1, Second Work Unit W2 Control the system to accept any of the following operations.

[0096] Specifically, the one-sided operation processing unit 32 sets the front table selection button 64a and the rear table selection button 64b on the table selection frame 64 of the operation screen 61 displayed on the monitor 14 of the front first operation unit P1 to be selectable. The one-sided operation processing unit 32 then displays the operation items for the substrate transport lane and work area on the side selected by the table selection frame 64 and controls the unit to accept operations for those items.

[0097] In Figure 12(b), the rear table selection button 64b is selected. As a result, the monitor 14 of the front first operation unit P1 displays the operation items for the second substrate transport lane L2 and the second work unit W2. The one-sided operation processing unit 32 controls the touchscreen 13 of the front first operation unit P1 to accept only operations for the second substrate transport lane L2 and the second work unit W2. This allows, for example, the front first operation unit P1 to switch between operating the front table and operating the rear table.

[0098] Next, the control by the control unit 20 in the alternating mounting mode will be described. In non-independent mounting modes such as the alternating mounting mode, the area in which the first component mounting head H1 moves and the area in which the second component mounting head H2 moves overlap with each other during component mounting (see Figure 4(b)). Therefore, in non-independent mounting modes, mutual exclusion processing is performed to prevent interference between the first component mounting head H1 and the second component mounting head H2 when operated from multiple operation units (first operation unit P1, second operation unit P2).

[0099] In Figure 5, mutual exclusion processing is performed by the mutual exclusion processing unit 24 and the one-sided operation processing unit 32 of the control unit 20. Based on the identification result of the operation unit output from the input processing unit 21 and the state of the work units (first work unit W1, second work unit W2) included in the device state data 36, ​​the mutual exclusion processing unit 24 controls the system to not accept operations from other operation units if there is a risk of interference between the first component mounting head H1 and the second component mounting head H2.

[0100] Then, if the first operation unit P1 or the second operation unit P2 receives an operation that conflicts with the operation of any of the multiple substrate transport lanes (first substrate transport lane L1, second substrate transport lane L2) or multiple work units (first work unit W1, second work unit W2), the one-sided operation processing unit 32 of the control unit 20 performs an exclusive operation that does not accept operations from the other operation unit. In other words, in non-independent mounting mode, the control unit 20 controls the multiple operation units (first operation unit P1, second operation unit P2) in one-sided operation mode.

[0101] Here, with reference to Figure 13, an example of the operation screen 65 displayed on the monitor 14 of the first operation unit P1 during component mounting in alternating mounting mode will be described. Unlike the operation screens 55 and 61 in independent mounting mode, the operation mode selection frames 59 and 63 are not displayed in the work details display area 66. In addition, the front table selection button 67a and the rear table selection button 67b of the table selection frame 67 are set to be selectable. The mutual exclusion processing unit 24 processes the work details display area 66 in such a way that operations conflict with any of the operations of multiple board transport lanes (first board transport lane L1, second board transport lane L2) and multiple work units (first work unit W1, second work unit W2) that it rejects (does not accept).

[0102] Thus, in the independent implementation mode, the display unit (monitor 14) of the operation unit (first operation unit P1, second operation unit P2) displays a switch button (radio buttons in operation mode selection frames 59, 63) that accepts switching between one-sided operation mode and two-sided operation mode, the input unit (touchscreen 13) receives operation information from the switch button, and the control unit 20 changes the control of the multiple operation units between one-sided operation mode and two-sided operation mode based on the operation information (Figures 12(a), 12(b)).

[0103] In the dual-sided operation mode, the display unit (monitor 14) of the first operation unit P1 displays operation items that accept operations for the first substrate transport lane L1 and the first work unit W1, and the display unit (monitor 14) of the second operation unit P2 displays operation items that accept operations for the second substrate transport lane L2 and the second work unit W2 (Figure 12(a)). In the single-sided operation mode, the display unit (monitor 14) of the operation unit for which the single-sided operation mode is selected from among the multiple operation units (first operation unit P1, second operation unit P2) displays operation items that accept operations for any of the multiple substrate transport lanes (first substrate transport lane L1, second substrate transport lane L2) and multiple work units (first work unit W1, second work unit W2) (Figure 12(b)). Furthermore, in alternating mounting mode, the display units (monitor 14) of the multiple operation units (first operation unit P1, second operation unit P2) display operation items that accept operations from any of the multiple board transport lanes (first board transport lane L1, second board transport lane L2) and multiple work units (first work unit W1, second work unit W2) (Figure 13).

[0104] As described above, the two-stage / two-head component mounting devices M1 to M4 of this embodiment include a plurality of substrate transport lanes (first substrate transport lane L1, second substrate transport lane L2) for transporting and positioning the substrate 2, a plurality of component supply units (first component supply unit S1, second component supply unit S2) for supplying components, a plurality of work units (first work unit W1, second work unit W2) that perform work including component mounting, such as receiving components from the component supply units and mounting them on the substrate 2, a control unit 20 that controls the plurality of work units in independent mounting mode or non-independent mounting mode, and a plurality of operation units (first operation unit P1, second operation unit P2) connected to the control unit 20.

[0105] In the independent mounting mode, the control unit 20 controls the multiple operation units such that, in the double-sided operation mode, the first operation unit P1 accepts only operations for the first substrate transport lane L1 and the first work unit W1, and the second operation unit P2 accepts only operations for the second substrate transport lane L2 and the second work unit W2. In the independent mounting mode, the control unit 20 controls the multiple operation units such that only the operation unit for which the single-sided operation mode is selected accepts operations for the first substrate transport lane L1, the first work unit W1, the second substrate transport lane L2, and the second work unit W2. In the alternating mounting mode, the control unit 20 controls the multiple operation units such that the first operation unit P1 and the second operation unit P2 accept operations for the first substrate transport lane L1, the first work unit W1, the second substrate transport lane L2, and the second work unit W2. This allows for the appropriate operation of multiple work units (first work unit W1, second work unit W2) from multiple operating units (first operating unit P1, second operating unit P2).

[0106] The above describes the control unit 20 of the 2-stage / 2-head component mounting devices M1 to M4, but the control units of the 4-stage / 4-head component mounting devices M5 and M6 are similar. Specifically, in the case of the dual-sided operation mode of the independent mounting mode, the control units of the component mounting devices M5 and M6 control the multiple operation units such that the first operation unit P1 accepts only operations for the first substrate transport lane L1 and the first work unit W1 or the third work unit W3, and the second operation unit P2 accepts only operations for the second substrate transport lane L2 and the second work unit W2 or the fourth work unit W4. In the case of the single-sided operation mode of the independent mounting mode, the control units of the component mounting devices M5 and M6 control the multiple operation units such that only the operation unit for which the single-sided operation mode is selected accepts operations for the first substrate transport lane L1, the first work unit W1, the second substrate transport lane L2, the second work unit W2, the third work unit W3, and the fourth work unit W4. Furthermore, in alternating mounting mode, the control units of component mounting devices M5 and M6 control the multiple operating units, namely the first operating unit P1 and the second operating unit P2, so that they accept operations for the first substrate transport lane L1, the first work unit W1, the second substrate transport lane L2, the second work unit W2, the third work unit W3, and the fourth work unit W4. This allows for appropriate operation of the multiple work units (first work unit W1, second work unit W2, third work unit W3, and fourth work unit W4) from the multiple operating units (first operating unit P1 and second operating unit P2).
