[0036]
In the cassette designation information table shown in FIG. 4C, the device number data “1” and “2” stored in the device number column 111 in the device number column 83 of the device data table in FIG. , ... are stored in the same data. Also in this case, the cassette type column 112 is provided as a parent column, and the position number columns 112-1, 112-2,. In the case of this table, cassette type data is stored in these position number fields 112-1, 112-2,. The example in the figure shows that the type “8MMP” parts cassette is arranged at the arrangement positions of the third and fourth in the model of the apparatus number “1”, and 4 in the model of the apparatus number “2”. This indicates that a component cassette of the type “STCK” is disposed at the position where the number is disposed. As will be described later, the cassette position in the cassette designation information table is the finally determined placement position of each component cassette.
[0037]

In this process, the component data table shown in FIG. 3B is referred to, the component type is retrieved from the component type column 71, and the suckable nozzle corresponding to the component type detected by this search is the suckable nozzle. Extracted from the columns 73a, 73b,.
[0046]
Next, the nozzle extracted as being capable of sucking the designated component and the device for designating the placement position of the component cassette (the component mounting device designated prior to this processing, 1 in this example) It is confirmed whether or not there is a coincidence among the nozzles (all nozzles accommodated in the nozzle exchanger) attached to the number machine (designated in advance) (step S7). In this process, the device data table shown in FIG. 3 (c) is referenced, and “1” No. 1 machine is searched from the device number column 83, and all nozzle data (name data) corresponding to the No. 1 machine detected by this search is searched. ) Are extracted from the nozzle columns 85a, 85b, 85c,..., And the extracted nozzle data is compared with the nozzle data obtained based on the specified parts, and some of them match. Is determined.
[0047]
Subsequently, the suctionable nozzle information is displayed (step S8). In this process, as a determination result by the comparison, as shown in FIG. 8C, for example, the suckable nozzles in the nozzle exchanger are visually displayed. This display is displayed in an appropriate area in the screen displayed with a screen configuration different from the display of FIG. Further, the display of FIG. 8 (c) is slightly different from that of FIG. 7 in order to explain examples in various cases, but in actuality, an example of display showing the nozzle changer 123 of FIG. 7 more visually. It is. In the example of FIG. 8 (c), it is shown that the three nozzles on the left are nozzles that can be picked up according to the type of the specified component, and the next two nozzles cannot be picked up. It is shown that. And in this example, it has shown that the nozzle is not accommodated in the accommodating part of the right end of a nozzle exchanger.
[0048]
If there is no match between the nozzles extracted from the part data table and the nozzles in the nozzle exchanger in the confirmation process in step S7, all the nozzles cannot be picked up in the display of FIG. 8 (c). Displayed as a nozzle.
[0049]
Subsequently, the component type is obtained again by referring to the component list table of FIG. 3A based on the selected component name (step S9), and the component data table of FIG. 3B is referred to based on this component type. Thus, the camera type is obtained (step S10). Then, based on the obtained camera type, the device data table of FIG. 3C is referred to determine whether or not it matches the type of the camera mounted on the device (step S11). The result is displayed (step S12). In this processing, for example, as shown in FIG. 8D, the component recognition camera mounted on the component mounting apparatus is visually displayed. In the example shown in FIG. 8D, there are three component recognition cameras mounted on this component mounting apparatus, and all three can recognize the component “A200” (even if the image is not divided). It is displayed with coloring (hatching in the example in the figure) indicating that the whole part can be recognized at once. If the recognition is poor (if the image is not divided, the entire part will not enter the field of view), for example, it is displayed with a simple square frame without coloring.
[0050]
Subsequently, the cassette designation information (number data of the attachment position) of the other parts already attached, the cassette attachment availability information of the apparatus to be attached (part mounting apparatus), the suckable nozzle of the apparatus, and the cassette width information Based on the above, it is confirmed whether the component cassette can be mounted (step S13), and the confirmed cassette mounting information is displayed (step S14).
[0051]
In this process, for example, as shown in FIG. 9 (a), the cassette cassette-selected parts cassette table is visually displayed (in the example of this figure, the parts cassette 121 at the front of the apparatus), and the designated mounting position is displayed. Is displayed in a predetermined color (indicated by black in the example in the figure), and in the case of a cassette that protrudes to the left and right, the protruding part is displayed in another predetermined color (indicated by cross hatching in the figure). If there are other mounting positions that can be mounted (can be specified), they are displayed in a predetermined color (indicated by self-colored in the example in the figure), and the mounting of another cassette has already been specified (determined), Alternatively, a mounting position where a tray feeder or the like is determined to be mounted and another cassette cannot be mounted is displayed in a predetermined color (indicated by hatching in the drawing) indicating that the cassette cannot be mounted.
[0052]
Next, the process of step S10 for performing the display process as described above will be further described with reference to the flowchart shown in FIG. In this process, a register CT built in the CPU 50 (an area CT may be provided in the RAM 53) is used. First, a temporary cassette number “1” is set in the register CT and initialized (step S21). Subsequently, it is determined whether or not the value of the register CT exceeds the maximum number of cassettes (see the number data in the cassette position column 103 of the cassette mountability information table in FIG. 4B, 74 in the example shown in FIG. 7). (Step S22) After confirming that it has not exceeded (N in S22), there is a recognizable camera (a component recognition camera capable of recognizing the selected component is mounted on the component mounting apparatus). ) With reference to the apparatus data table of FIG. 3C (step S23).
[0053]
If there is a recognizable camera (Y in S23), whether or not there is a nozzle that can be attracted to the component mounting apparatus is determined by referring to the component data table of FIG. 3 (b) and FIG. 3 (c). A determination is made based on the device data table (step S24). If there is a nozzle that can be sucked (S24 is Y), referring to the cassette mountability information table shown in FIG. 4B, whether the number indicated by the register CT is a cassette mountable position or not. Is determined (step S25).
[0054]
If it is the position where the cassette can be attached (S25 is Y), the cassette designation information table shown in FIG. 4C and the cassette width information table shown in FIG. It is discriminated whether or not it interferes with the existing cassette (step S26). If there is no interference (Y in S26), the position indicated by the number of the register CT is displayed as a place where the cassette of the selected part can be attached (step S27).
[0055]
As a result, one white frame portion shown during the display of the parts cassette stand in FIG. 9A is first displayed. Regardless of the result of the determination in step S23, S24, S25, or S26, in any case, it is displayed that it cannot be immediately attached at the position indicated by the register CT (step S28).
[0056]
After processing step S27 or step S28, the register CT is incremented by "1", the cassette position number to be determined is incremented by one (step S29), the process returns to step S22, and steps S22 to S29 are performed again. repeat. Steps S23 until the register CT is sequentially incremented to the position indicated by the hatched numbers 1 to 10 (non-attachable area) shown in the display of the parts cassette stand in FIG. 9A until the register CT is sequentially incremented to “10”. , S24, S25, or S26 is a display example when the determination is “No”.
[0057]
Then, the register CT is sequentially incremented, steps S22 to S29 are repeated, and the determinations at steps S23, S24, S25, and S26 are all “OK”, and the display of the parts cassette stand in FIG. When the number of frames (empty areas) increases and eventually the value of the register CT exceeds the maximum number of cassettes in step S22 (Y in S22), for the cassettes that have already been designated, If there is an overhanging portion, the overhanging portion is also displayed (see step S30, display portion 125 in FIG. 9A). As a result, as shown in FIG. 9A, the display for visually confirming the place (position) where the operator can attach the cassette is completed.
[0058]
Subsequently, based on the above display, the operator selects, for example, the component “A200” which is selected and highlighted from the parts table shown in FIG. By using drag and drop, the cassette number (position number on the parts cassette stand) is designated in the empty area of FIG. As a result, as shown in FIG. 9B, the display 126 of the designated cassette position of the part “A200” is displayed in the vicinity of the display 125 where the designation of the other cassette has already been completed.
[0059]
FIG. 10 is a flowchart of processing performed based on this cassette designation input. First, it is determined whether there is a recognizable camera (step S40). This process is based on the specified part (part type), and the camera type obtained from FIG. 3 (b) and the camera type obtained from the device table in FIG. This is a process for reconfirming whether there is a camera capable of recognizing the component. If there is a recognizable camera (S40 is Y), it is next determined whether or not there is a nozzle that can be sucked (step S41). This processing is obtained from the name of the suckable nozzle obtained from the part data table of FIG. 3B based on the designated part (part type) and the apparatus data table of FIG. This is a process of reconfirming whether or not there is a nozzle capable of sucking the designated part in the device (No. 1 machine) based on the nozzle name. If there is a nozzle that can be sucked (S41 is Y), it is then determined whether or not the designated mounting position is a position that can be mounted (step S42). In this process, the cassette type obtained from the parts data table in FIG. 3B based on the designated parts and the mountable position information obtained from the cassette mountability information table in FIG. 4B. From the above, it is determined whether or not the designated attachment position is a position that can be attached in the initial condition.
[0060]
If the position can be attached (S42 is Y), the cassette type obtained from the component data table of FIG. 3B and the cassette width obtained from the cassette width information table of FIG. Based on the information, it is determined whether or not the position designated by the cassette is a position that does not interfere with another cassette that has already been determined to be mounted (step S43).
[0061]
If there is no interference (Y in S43), it is reflected in the parts list (step S44). In this process, the number data of the arrangement position confirmed not to interfere with the other cassette is written in the cassette position column 65 corresponding to the designated part in the parts list table shown in FIG. It is.
[0062]
Subsequently to the above, it is reflected in the cassette designation information (step S45), and then the cassette mounting information is displayed based on the cassette designation information after the reflection (step S46). As a result, the display 126 shown in FIG. Then, the process ends.
[0063]
The process to be reflected in the cassette designation information corresponds to the designated arrangement position in the cassette position column 112 corresponding to the apparatus (the first machine in this example) in the cassette designation information table shown in FIG. This is a process of writing the type data of the cassette corresponding to the component in the position number columns 112-1 to 112-5,. Thus, for example, the display contents shown in FIG. 9A are displayed while being sequentially updated for the parts specified thereafter.
[0064]
In this way, the arrangement of the designated component cassette is determined at the designated or redesignated arrangement position while confirming that the nozzle that can be picked up and the position where it does not interfere with other cassettes are confirmed. It will be done. Then, the determined information is taken as a parameter in the component mounting program of the first machine, and the component mounting operation is executed.
[0065]
【The invention's effect】
