[0007]
In addition, the parts cassette bases 11 and 12 are disposed on the front part and the rear part on the base 4, respectively. On these component cassette tables 11 and 12, component supply devices such as a component supply cassette, a component supply pallet, and a component supply stick corresponding to each of a plurality of types of components to be mounted on the substrate are arranged in advance prior to the component mounting process. . Between the component cassette table 11 and the fixed substrate guide rail 6a, a component recognition camera, a suction nozzle exchanger, and the like, which are not visible in the figure, are arranged, and the component cassette table 12 and the movable substrate guide rail are arranged. Similarly, a component recognition camera and a suction nozzle exchanger are also provided between 6b and 6b. A plurality of types of suction nozzles are held in the suction nozzle exchanger.
[0008]
In the substrate transport path between the substrate guide rails 6a and 6b, a substrate support plate is disposed below the substrate guided rails 6a and 6b and the substrate carried by the conveyor belt, and supports the substrate by ascending from the bottom. At the same time, the positioning pins are inserted into the positioning holes of the substrate to position the substrate.
[0009]
The work tower 10 is connected to the central control unit of the apparatus main body by a flexible belt-like cable 13 as shown in FIGS.

It comes to be installed. The various data in the component table includes, for example, data such as a component code, a name related to the type, a vertical and horizontal height size of the component, and a missing portion with respect to the reference shape.
[0012]
[Problems to be solved by the invention]
By the way, various component data in the above-described component table are input by the operator in the setup operation prior to the start of the component mounting operation. This input is performed by the data creation device, and the created data is written into the program area of the memory of the component mounting device via a medium such as a communication cable or a floppy desk.
[0013]
In general, there are a wide variety of types of components mounted on a board by a component mounting apparatus, and the size-related data is not only simply vertical and horizontal heights, but also often requires dimensions of incidental portions, which are extremely complicated. Moreover, various shapes vary depending on the parts. Therefore, inputting these data requires a high degree of skill and takes time and effort. In addition, there is a problem that it is difficult to confirm that there is no error in the input data.
[0014]
However, Japanese Patent Laid-Open No. 9-293091 discloses a data creation apparatus that reduces the complexity of data input work by visually displaying parts. However, this only visually aids the data input operation, and does not show a method for allowing the data creation apparatus to determine whether or not the input data is correctly input.
[0015]
For example, a component configured by forming a predetermined missing portion with respect to a reference shape cannot be correctly connected to a printed circuit when mounted on a board unless the position of the missing portion is correctly recognized. For example, in the case of fine parts, if the missing part is formed in the lead terminals arranged with a dimension of 1 mm or less and the interval, it is too fine when entering the data while looking at the actual part, and the model record of the part manufacturer There is a risk of mistaken reading of the sequence number when entering data. In any case, this is a work with a high rate of errors in input. Therefore, it is necessary to confirm whether or not there is an error in the input data after the data input is completed.
[0016]
An object of the present invention is to provide a data creation device that immediately displays a shape image of a part according to input data together with a scale after data input in view of the above-described conventional situation.
[0017]
[Means for Solving the Problems]
A data creation device of the present invention is a data creation device for creating data of a component mounted on a board by a component mounting device, and is inputted with a component type data input means for inputting component type data indicating the type of component. Data input part display means for displaying a part shape image corresponding to the part type data together with a part shape data input part including at least the part size, data input means for inputting part shape data including at least the part size, and the data An input for displaying a display area scaled in dimension units of dimension data input by the input means and displaying a part shape image based on the input part shape data in the display area in a size corresponding to the scale. And a result image display means.
[0018]
The input result image display means switches the display screen by the data input part display means to switch the scale every time input of one item of the part shape data by the data input means is completed. The display area and the part shape image based on the input part shape data are displayed.
[0019]
And, for example, as described in claim 3, scale unit dimension changing means for changing the unit scale of the scale by input, and data for converting the unit of the inputted part size data corresponding to the changed unit dimension And a unit changing means.
[0020]
The scale displayed in the display area is visually distinguished from other scale parts for each predetermined unit, for example. Further, the input result image display means displays the part shape image by a display method different from the display of the scale, for example. In addition, the data input means includes, for example, a missing data input means for inputting missing data of a predetermined missing part that is missing with respect to the reference shape of the part as described in claim 6. In this case, For example, as described in claim 7, the input result image display means is configured to distinguish and display a non-missing portion with respect to a reference shape of the part and the predetermined missing portion by visually different displays.

The scale image is calculated based on the inputted dimension data, and the shape image of the part obtained as a result and the scaled display area are overlapped and displayed on the display 31.
[0025]
FIG. 2 is a flowchart showing the operation of component data creation processing by the data creation device 20 configured as described above. In this process, the part size data input by the operator is only a numerical value, and the unit is fixed to mm (millimeter). The HDD 26 stores a component shape data table 35 and a component external size data table 36 read from the outside, and is read into the RAM 25 as needed to refer to the data.
[0026]
3 (a) and 3 (b) are diagrams showing the display state of the input data displayed on the screen of the display 31 in the above processing, respectively, and FIGS. 4 (a), (b) and FIG. It is a figure which shows the display state of the input result each displayed on a display in said process. The processing of FIG. 2 will be described below with reference to FIGS. First, in the flowchart of FIG. 2, data such as a component code, a component size, and missing shape information are input (step S1).
[0027]
In this process, first, as shown in FIG. 3A, the part code is input to the input area 41 of the display screen 40, for example, “38601”, and the dimension of the part in the X direction is input to the input area 42 below it. “14.40” is input, and the dimension in the Y direction of the part is input, for example, “7.62” in the input area 43 below it. Further, the height of the part ( For example, “2.50” is input as the dimension in the Z direction). If there is an input mistake, click the upward triangle button or the downward triangle button at the rear of the input area with the mouse to change the entered numerical value in small increments. In addition, it is input whether the supply is performed by a component tape cassette, a component tray, or a component stick. In the case of a component cassette, data such as how many times the tape can be sucked is input.
[0028]
If the part has a missing part with respect to the standard form of the lead, for example, the display is switched to the display screen 45 as shown in FIG. To do. In the upper left of the display screen 45 shown in FIG. 4B, the approximate shape of the component 46 of the input component code “38601” is displayed. This display shows the orientation of the component when the component is loaded from the bottom to the top and mounted on the printed circuit board.
[0029]
Check buttons 47 and 48 are displayed above and below the display frame of the component 46. In FIG. 5B, since the lower button 48 is clicked with the mouse, a click mark is displayed in the button 48. As a result, the input display for the lead 49 at the lower part of the screen of the component 46 is set as shown in the data input area display 51 shown on the right side. The lead of the component 46 is numbered from right to left in the case of the lead at the top of the screen, number 1, 2,..., And the lead from the left to the right in the case of the lead at the bottom of the screen, Numbers 2 and so on are assigned.
[0030]
Accordingly, as shown in the data input area display 51, square input buttons 52 (52-1, 52-2,..., 52-12) with numbers 1 to 12 are displayed. The The number of the input button for the lead on one side (here, the lower side) of the part 46 is up to “12”, indicating that there are 12 standard type leads of the part 46 on one side. .
[0031]
The operator clicks the button corresponding to the number of the missing part with the mouse while looking at the model record or the actual part. In the example of FIG. 5B, the second button 52-2, the fifth button 52-5, and the ninth button 52-9 are clicked. Thus, in the data input, the input format is set in the display area in the upper half of the display screen of the display 31, and the input data is displayed.
[0032]
2, in the flowchart of FIG. 2, the component shape data table 35 is searched, and the component shape data of the component 46 of the input component code “38601” (shape classification data and each size Data) is read into a predetermined area of the RAM 25 (step S2).
[0033]
Based on the read part shape data, the input result is displayed on the display screen 55 showing the input result, as shown in FIG. In the left display area 59 of FIG. 6A, the measurement positions of the external dimensions X2 and Y2 of the component 46, the width LW1 of each lead, its length LL1, and its arrangement pitch LP1 are shown. In the other display areas 56 and 57, the respective numerical values are displayed as, for example, “15.62” for X2 and “1.27” for LP1.
[0034]
Subsequently, the component outer size data table 36 is searched to read the component outer size data of the component 46 having the input component code “38601” (step S3).
[0035]
When the “View” button 58 is clicked with the mouse, the display shown in FIG. 4B is made. This display is performed by the processing after step S4 in the flowchart of FIG. That is, first, a display scale is calculated based on the component external size data read in step S3 described above (step S4). In this process, a scale is calculated for displaying the entire lead portion including the missing portion in a full display area 59 shown in FIG.
[0036]
Subsequently, a scale display scale for indicating the component dimensions is calculated (step S5). In this process, the dimensions of individual parts cannot be confirmed by simply enlarging and displaying the outline of the component 46 shown in FIG. 4 (a) in the display area 59 of FIG. 4 (b). Therefore, it is necessary to display the vertical scale 61 and the horizontal scale 62. For this purpose, the scale for the display area 59 of the display scales 61 and 62 is calculated.
[0037]
With this calculation, when the scale of the external display of the component 46 and the scale of the vertical and horizontal display scales are calculated, first, the vertical and horizontal scales are drawn based on the calculation results (step S6). Thereby, the vertical scale 61 and the horizontal scale 62 are drawn in the display area 59 as shown in FIG. These scales are drawn with green lines, for example.
[0038]
Further, subsequently, a process of drawing the shape of the component 46 so as to overlap the display of the vertical and horizontal scales of the display area 59 based on the calculated scale is performed (step S7). As a result, as shown in the display area 59 in FIG. 4B, the part shape 63 is displayed overlapping the scale display. The display is immediately changed by the above input when the check box (□) next to the “View” button is checked (v).
[0039]
Thus, the display screen 55 or 60 showing the input result is performed using the lower half of the display screen of the display 31. In the upper half, not shown, the data input screen shown in FIG. 3 (a) or FIG. 3 (b) is displayed in association with the input result display screen shown in FIG. 4 (a) or FIG. 4 (b). Is done.
[0040]
The shape 63 of the component is shown with hatching in FIG. 4B. However, in the actual display, it is easy to distinguish even if only the outline is drawn with, for example, a red line. . The units of the scales 61 and 62 are set to 1 mm regardless of the display size.
[0041]
As a result, the operator looks at the shape 63 of the component 46 displayed together with the scales 61 and 62 in the display area 59 of FIG. 4B and looks at the width dimension, length dimension, and missing part 65 of the enlarged display lead 64. -2, 65-5, 65-9, etc. Input data errors or settings data registered in advance in the part shape data table 35 or the part outline data table 36 immediately and easily after data input Can be found in
[0042]
FIG. 5 is a diagram illustrating a display example of the display area 59 when the shape of the component is smaller. As shown in the display areas 56 and 57 on the right side of the display screen 70 in the figure, the external dimensions of this component are extremely small, with X2 being “9.50” and Y2 being “4.30”. On the other hand, the horizontal scale 71 and the vertical scale 72 displayed in the display area 59 on the left side of the screen 70 are extremely large as compared with the case of FIG. 4B, but one scale of FIG. It is 1 mm like the one scale of). Accordingly, it can be seen at a glance that the outer shape of the component 73 displayed in the display area 59 is small.
[0043]
【The invention's effect】
As described above in detail, according to the present invention, the external dimensions and direction of a component are automatically changed to a desired scale immediately after input according to input data and displayed on a display device. The input data confirmation work to be recognized by the device can be performed in a short time and accurately, thereby preventing input mistakes in new part data registration work and existing part data change work and work. Improves efficiency.
