BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cassette placement position designating device, and more particularly, to a cassette placement position designating device for visually displaying a position at which a supply cassette for a designated component is to be placed. .

[0002]

2. Description of the Related Art Conventionally, there is a component mounting apparatus as shown in FIGS. 11 (a) and 11 (b). FIG. 1A is an external perspective view of the component mounting apparatus, and shows a perspective view from above the base. FIG. 2B is a plan view showing various devices directly disposed on the base, and FIG.
The configuration of each part shown in FIG.

The component mounting apparatus shown in FIGS. 1 (a) and 1 (b) includes a base 3 surrounded by a lower protective cover 1 and covered by an upper protective cover 2 above. Various devices are arranged on the upper part. Inside the base 3, there are provided a central control unit for controlling each unit, a support plate device 4 for supporting a substrate carried in from a device at a stage preceding the line from below, and the like. An input device including a liquid crystal display and a touch panel is provided on the front surface of the upper protective cover 2, and various instructions can be input by an external operation.

[0004] On the base 3, fixed and movable 1
A pair of parallel substrate guide rails 5a and 5b extend horizontally in the substrate transport direction (X-axis direction, right to left in the figure). A plurality of loop-shaped conveyor belts, which cannot be clearly seen in the drawing but are in contact with the lower portions of the board guide rails 5a and 5b, are movably disposed. The conveyor belt has a belt side with a width of several millimeters on each of the board guide rails 5.
The device is driven by a belt drive motor while looking into the substrate transport path from underneath a or 5b, travels in the substrate transport direction, and transports the substrate while supporting both sides of the back surface of the substrate from below. The support plate device 4 is disposed in a substrate transport path between the substrate guide rails 5a and 5b. The support plate device 4 supports the substrate carried into the transport path by ascending from below and positioning pins on the substrate. The board is positioned by inserting it into the positioning hole.

[0005] A pair of left and right fixed rails (Y-axis rails) extending in parallel to a direction (Y-axis direction) perpendicular to the substrate transfer direction (X-axis direction) over the pair of board guide rails 5a and 5b. 6a and 6b are provided. A long moving rail (X-axis rail) 7 is slidably engaged with the Y-axis rails 6a and 6b, and a work tower 8 is slidably suspended on the X-axis rail 7. The work tower 8 has a plurality (usually 2
The working heads of 7) to 7) are vertically movable by a cylinder device or the like.

An X-axis direction drive motor (not shown) rotates in both forward and reverse directions according to an instruction from the central control unit to drive the work tower 8 via a drive transmission system, whereby the work tower 8 can be freely moved in the X-axis direction. To slide. The Y-axis direction drive motor (not shown) rotates in both forward and reverse directions to drive the X-axis rail 7 via the drive transmission system, so that the X-axis rail 7 slides freely in the Y-axis direction. As a result, the working head moves freely up and down, left and right, and back and forth.

On the base 3, a parts cassette table 9a is provided at the front.
A component cassette table 9b is disposed at the rear. Three component recognition cameras 11 and three nozzle exchangers 12 are arranged between the component cassette table 9a of the base 3 and the fixed board guide rail 5a, and the three component recognition cameras 11 and the movable board guide rail 5b are connected to each other. Also, three component recognition cameras 13 are provided between them.

A component cassette corresponding to each of a plurality of types of components to be mounted on a substrate is detachably mounted on the component cassette tables 9a and 9b in advance. Among the component cassettes, for example, a tape-type component cassette winds a component tape in which a large number of components are sandwiched between two tape-shaped members and stored, and the tape is sequentially fed out from a supply unit at a front end portion. Are supplied to the working head one by one.

The nozzle exchanger 12 contains a plurality of suction nozzles (six in the drawing). Suction nozzles having different sizes and structures at the tip of the nozzle corresponding to the size of the component to be sucked are prepared. The work head of the work tower 8 first selects a suction nozzle corresponding to a component to be mounted on a substrate from the nozzle exchanger 12 and mounts it (or replaces and mounts it with a previous one). Then, a desired component is sucked and moved to a mounting position on the board.

The component recognition camera 11 (or 13) stands by while the work head is moving, and images the component being sucked by the suction nozzle from below to detect a holding position deviation. The central control unit corrects the moving amount and the rotating amount of the working head based on the detected position deviation and mounts the component at a predetermined position on the board.

As described above, in order to drive the work head to suck the components from the component cassettes on the component cassette table 9a or 9b and efficiently mount the components on the board, the component cassettes must be arranged on the component cassette table. The position needs to be set optimally. Such an operation of setting the disposition position of the component cassette is also performed at the first start-up of the component mounting apparatus. However, it is preferable to change the disposition position of the component cassette during the operation. This is often done in such cases. Editing work such as setting or changing the arrangement position of the component cassettes has been performed by manually inputting data into a predetermined table format.

[0012]

However, according to the above-described manual method, the operator can determine whether or not the component cassette can be mounted at a designated arrangement position, or whether the component cassette is to be suctioned. Must be well-known in advance, such as whether or not is stored in the nozzle exchanger of the corresponding component mounting apparatus. For example, when the number of nozzles that the user has for each type is insufficient, the same type of nozzle (for example, nozzle A) is accommodated in two component mounting apparatuses (for example, No. 1 and No. 2) arranged in one line. May not be possible. Therefore, there is a case where the nozzle A is housed only in the (first nozzle changer). In such a case, the component cassette of the component to be picked up by the nozzle A is placed on the component cassette table of the first machine, and
It cannot be placed on Unit No. The operator needs to know such conditions in advance. Further, assuming that the component cassette is arranged in the first machine, for example,
It is necessary to quickly determine which of the arrangement positions up to the number should be arranged, or that the arrangement is not possible even if one wants to arrange. Otherwise, it takes too much time to set the placement position of the component cassettes, and it takes too much time to start up the component mounting process of the line or to resume the process after the change in the layout, resulting in a problem that the work efficiency is reduced. I do.

However, a considerable skill is required for the operation of knowing the arrangement position of the nozzles suitable as described above and judging the position at which the nozzle can be arranged by knowing the characteristics of the component cassette. There is a problem that the human resources engaged in the work are limited.

Next, the nozzles extracted as being capable of picking up the specified component and a device for specifying the placement position of the component cassette (the component mounting device specified prior to this processing; In the example, it is checked whether or not there is a match with the nozzles (all the nozzles accommodated in the nozzle exchanger) mounted on the first machine (pre-designated) (step S7). In this process, FIG.
The device data table shown in (c) is referred to, the “No. 1” unit is searched from the device number column 83, and all the nozzle data (name data) corresponding to the first unit detected by this search is stored in the nozzle column 85a, , 85b, 85c,..., And the extracted nozzle data is compared with the nozzle data obtained based on the designated component to determine whether there is a match. You.

Subsequently, information on the nozzles that can be suctioned is displayed (step S8). In this process, as a result of the above-described comparison, for example, as shown in FIG. 8C, the nozzles that can be sucked in the nozzle exchanger are visually displayed. This display is displayed in an appropriate area in a screen displayed in a screen configuration different from the display of FIG. The display in FIG. 8C is slightly different from that in FIG. 7 in order to explain examples in various cases, but is actually a display example in which the nozzle exchanger 123 in FIG. It is. In the example of FIG. 8 (c),
This indicates that the three nozzles on the left are nozzles that can be sucked in accordance with the type of the specified component, and that the next two nozzles cannot be sucked. And, in this example, it is shown that the nozzle is not accommodated in the accommodation portion at the right end of the nozzle exchanger.

In the confirmation processing in step S7, if there is no coincidence between the nozzles extracted from the part data table and the nozzles in the nozzle exchanger, all the nozzles are suctioned in the display of FIG. It is displayed as an impossible nozzle.

Subsequently, the component type is obtained by referring to the component list table shown in FIG. 3A again based on the selected component name (step S9), and based on this component type, FIG.
The camera type is obtained with reference to the component data table (step S10). Then, based on the obtained camera type, referring to the device data table of FIG. 3 (c), it is determined whether or not it matches the type of the camera mounted on the device (step S11). The result is displayed (step S12). In this process, 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.
The component recognition camera mounted on this component mounting device is 3
The three components are colored (indicated by hatching in the example in the figure) to indicate that the above-mentioned component "A200" can be recognized (all components can be collectively recognized without dividing the image). Have been. If the recognition is not good (the whole part cannot be seen from view unless the image is divided), it is displayed as, for example, a simple square frame without coloring.

Subsequently, cassette designation information (number data of a mounting position) of another component already mounted, cassette mountability information of a device to be mounted (component mounting device), a suctionable nozzle of the device, Based on the cassette width information, it is confirmed whether or not the component cassette can be mounted (step S13), and the confirmed cassette mounting information is displayed (step S1).
4).

In this process, for example, as shown in FIG. 9 (a), the component cassette table selected for the cassette is visually displayed (in this example, the component cassette 12 at the front of the apparatus).
1) The specified mounting position is displayed in a predetermined color (in the example of the drawing, indicated by solid black), and in the case of a cassette that protrudes to the left and right, the protruding portion is another predetermined color (cross hatching in the figure). ). If there is another mounting position that can be mounted (specified), it is displayed in a predetermined color (in the example of the figure, it is shown as a solid color), and the mounting of another cassette has already been specified (determined). Alternatively, the attachment position where the attachment of the tray feeder or the like has been determined and other cassettes cannot be attached is displayed in a predetermined color (indicated by hatching in the figure) indicating that attachment is impossible.

Next, the processing in step S10 for performing the display processing 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 (the 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 S2).
1). Subsequently, the value of the register CT is set to the maximum number of cassettes (refer to the number data in the cassette position column 103 of the cassette mountability table of FIG. 4B, 7 in the example shown in FIG. 7).
4) It is determined whether or not exceeds (step S22),
Confirm that it does not exceed (S22 is N).
There is a recognizable camera (a component recognition camera capable of recognizing the selected component is mounted on the component mounting device)
Whether or not this is the case is determined with reference to the device data table of FIG. 3C (step S23).

If there is a recognizable camera (S2)
3 is Y), and then it is determined whether or not the component mounting apparatus has a nozzle capable of sucking based on the component data table of FIG. 3B and the device data table of FIG. S24). If there is a nozzle that can be sucked (S
24 is Y), and further, it is determined whether or not the number indicated by the register CT is the position where the cassette can be mounted by referring to the cassette mountability table shown in FIG. 4B (step S25).

If the position is a position where the cassette can be mounted (Y in S25), subsequently, referring to the cassette designation information table shown in FIG. 4C and the cassette width information table shown in FIG. It is determined whether or not it interferes with the attached cassette (step S26). And
When there is no interference (Y in S26), the position indicated by the register CT number is displayed as a place where the cassette of the selected component can be mounted (step S2).
7).

As a result, one white frame portion shown during the display of the parts cassette table in FIG. 9A is first displayed. In the determination of the above steps S23, S24, S25 or S26,
Regardless of which result is negative, in such a case, it is immediately displayed that it cannot be attached to the position indicated by the register CT (step S28).

After the processing in step S27 or step S28, the register CT is incremented by "1", the number of the cassette position to be judged is incremented by one (step S29), the flow returns to step S22, and the flow returns to step S2.
Steps 2 to S29 are repeated. Positions indicated by hatching numbers 1 to 10 (non-mountable areas) in the display of the component cassette table in FIG. 9A are registers CT.
Is a display example in which the determination is “No” in any of the above-described steps S23, S24, S25, or S26 until is sequentially incremented to “10”.

Then, the register CT is sequentially incremented, and steps S22 to S29 are repeated. All of the determinations in steps S23, S24, S25, and S26 become "OK" and the parts cassette table shown in FIG. The number of white frames (empty areas) increases in the display, and the above-described step S22 is performed.
When the value of the register CT exceeds the maximum number of cassettes (Y in S22), for a cassette already designated, the designated position and, if there is an overhanging portion, the portion including the overhanging portion is displayed. (Step S30, see display portion 125 in FIG. 9A). As a result, FIG.
As shown in (a), the display for the operator to visually confirm the place (position) where the cassette can be mounted is completed.

Subsequently, based on the above display, the part “A20” selected and highlighted from the parts table shown in FIG.
"0" is drag-and-
By dropping, a cassette number (position number on the component cassette table) is designated in the empty area of FIG. 9A. As a result, as shown in FIG. 9B, the component “A2” is displayed near the display 125 where the designation of another cassette has already been completed.
The display 126 of the designated cassette position of "00" is displayed.

FIG. 10 is a flowchart of a process performed based on this cassette designation input. First, it is determined whether there is a recognizable camera (step S4).
0). This processing is based on the camera type obtained from FIG. 3 (b) based on the specified component (component type), and FIG.
This is a process for confirming again whether or not there is a camera capable of recognizing the component in the device from the camera type obtained from the device table. If there is a camera that can be recognized (Y in S40), it is next determined whether or not there is a nozzle that can be sucked (step S41). This process is based on the name of the suction-capable nozzle obtained from the component data table of FIG. 3B based on the designated component (component type),
This is a process for reconfirming whether or not there is a nozzle capable of sucking the specified component in the device (No. 1) from the nozzle name obtained from the device data table of FIG. If there is a nozzle that can be sucked (Y in S41),
It is determined whether or not the specified attachment position is a position where attachment is possible (step S42). In this process, the cassette type obtained from the component data table shown in FIG. 3B based on the specified component and the cassette type shown in FIG.
From the mountable position information obtained from the cassette mountability information table of
It is determined whether or not the position is such that it can be attached in the initial condition.

Then, if it is a position where it can be attached (S
42 is Y), the cassette designation is made based on the cassette type obtained from the component data table shown in FIG. 3B and the cassette width information obtained from the cassette width information table shown in FIG. 4A. Then, it is determined whether or not the position is a position that does not interfere with another cassette whose attachment has already been determined (step S43).

If there is no interference (Y in S43), the result 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 into the cassette position column 65 corresponding to the specified component in the component list table shown in FIG. It is.

Subsequently, the information is reflected on the cassette designation information (step S45), and the cassette mounting information is displayed based on the reflected cassette designation information (step S46). As a result, the display 12 shown in FIG.
6 is determined. Then, the process ends.
