2. Description of the Related Art A conventional configuration example of an electronic component mounting apparatus will be described with reference to FIGS.

FIG. 4 is a perspective view showing the appearance of a conventional electronic component mounting apparatus. In FIG. 4, reference numeral 20 denotes a display device for displaying the status of the apparatus and the contents of a program, 21 denotes an input device having a keyboard or the like for inputting data, 22
Is a table for supplying electronic components, and has a unique number (hereinafter, referred to as a Z number) for identifying the position of a jig (hereinafter, referred to as a cassette) for supplying the electronic components.

FIG. 5 is a diagram showing types of programs necessary for producing a circuit board and their relationships.
In FIG. 5, reference numeral 23 defines an instruction for mounting an electronic component (referred to as a block for each instruction) and is referred to as an NC program. Numeral 24 defines the type of electronic component mounted on the cassette placed at that position with respect to Z number 30, and is called an array program. Here, by assigning a Z number to each block of the NC program 23,
The program and the array program 24 are associated via the Z number 30, and the type of electronic component mounted on the block is uniquely determined. Reference numeral 25 defines a type, shape, and supply method based on the electrical characteristics of the electronic component for each type of electronic component, and is referred to as a component library. In the component library 25, the component shape code 31 is given to each Z number 30 of the array program 24, using the component shape code 31 that uniquely identifies the type, shape, and supply method based on the electrical characteristics of the electronic component as a key. Thereby, the array program 24 and the component library 25 are associated via the component shape code 31. 26 is a mark necessary to teach the apparatus the relative position of the mark when calculating the inclination of the straight line connecting the two marts on the circuit board to correct the amount of deviation in the rotation direction of the circuit board. This is defined as the mark library, which defines the shape and properties of In the mark library 26, a mark shape code 37 for uniquely identifying the shape and properties of the mark is used as a key, and the mark shape code 37 is given to each block of the NC program 23 in an appropriate format according to the type of correction. Program 23 and mark library
26 is associated via the mark shape code 37.

FIG. 6 shows a part of the grammatical structure of the program. FIG. 6 (a) shows the structure of the NC program 23, and FIG. 6 (b) shows the structure of the array program 24. In FIG. 6A, reference numeral 27 denotes a block number, which indicates an order in which electronic components are mounted as they are.

In FIG. 6 (b), 30
Is a Z number, which identifies the position where a plurality of prepared cassettes are arranged in the electronic component supply table 22. Numeral 31 denotes a component shape code for identifying the type of electronic component to be mounted on the cassette arranged at the corresponding Z number 30, which is a component shape code defined in the component library 25 as shown in FIG.
One-to-one correspondence with 31.

In the electronic component mounting apparatus configured as described above, if an error in a program is found when converting the data into data for operating the apparatus with reference to FIGS. 7 to 9, the error is notified as an error. The procedure for correcting the program to eliminate the cause of occurrence will be described below.

[0007] Program errors are roughly classified into three types: parameter value range errors, program syntax errors, and program consistency errors. A parameter value range error indicates a state where each parameter value of each program is not defined in advance within the range permitted by the device. FIG. 7 is a table showing the definition range of each parameter value possessed by the NC program 23. The definition range differs depending on the type and specification of the electronic component mounting apparatus. In FIG. 7, 32 indicates the minimum value of the parameter, and 33 indicates the maximum value. In the editing function of each program inside or outside the device, in order to give priority to the versatility and compatibility of the program basically, parameter values that are not included in the defined range depending on the type and specifications of the electronic component mounting device It is possible to create a program with Therefore, it is necessary to verify the suitability of the parameter values according to the type and specification of the device.

A grammatical error in a program indicates a state in which each program does not have a format according to a predetermined grammatical rule. FIG. 8 shows an example of the NC program 23 having a syntax error. In FIG. 8, reference numeral 34 denotes a column for specifying a command code for correcting the rotation direction using a mark on the circuit board, and is referred to as a mark correction command code. Reference numeral 35 denotes a block A which designates a command code for correcting the rotation direction of the entire circuit board based on two mark positions arranged on a diagonal line of the circuit board, and is referred to as a mark correction command block A. Blocks other than the mark correction command block A35 are supplied with a normal mounting command. According to the grammar rules of the NC program 23, since the apparatus sequentially processes the NC program from the beginning, the block of the correction command by the mark is defined to be described before the normal mounting block. program
23 is determined to be an NC program description order error.

An error in the consistency between the programs indicates a state in which the reference destination of the parameter relating to each program shown in FIG. 5 cannot be specified in the combination of the programs selected in the production of the circuit board. For example, FIG.
If the Z number requested by the mounting instruction block 36 of the NC program 23 shown in FIG. 6A is Zm, the part shape code 3 corresponding to Zm is obtained from the simultaneously selected array program 24 shown in FIG.
If 1 is not defined, the type of electronic component to be mounted in the mounting command block 36 cannot be specified. Similarly, the part shape code described in the array program 24
If the component 31 is not defined in the component library 25, an error occurs as a consistency error.

FIG. 9 shows an example of a notification message displayed on the display device 20 when an error occurs during the conversion into data for operating the electronic component mounting apparatus, which indicates an NC program description order error. ing. In the case of a parameter value range error, the name of the target program and the location of the error are displayed together with the range error message. The operator selects a menu for starting the edit screen of the target program on the display device 20 based on the message, finds the location where the error occurred in the edit screen, and corrects the appropriate value and format. I do. The result of the correction is confirmed by performing conversion to data for operating the electronic component mounting apparatus again.

[0011]

However, in the above-described configuration, after an error occurs, a step of searching for the location where the error occurs is inevitably performed by the operator. It takes some time to return to the production process. This step is frequently caused particularly when a newly created program is used for switching the product type, or when a combination of programs is changed. As a result, the operation rate of the electronic component mounting apparatus is greatly reduced.

[0012] Further, as shown in FIG. 9, although the error notification message and the location of the error allow the operator to correctly understand the cause of the error and assist in making an appropriate correction, the error is directly or indirectly performed. Does not provide a means to pinpoint the exact cause of the error, and ultimately depends on the operator's trial-and-error correction. There was a problem that the operation was not efficient. Especially program 2
Depending on the nature of the error, it is necessary to investigate the cause of the consistency error between 3 and 24 while referring to multiple programs 23 and 24 and libraries 25 and 26, and to correct multiple corresponding locations. Performing these corrections at will of the operator based only on the location of the error displayed on the screen has been insufficient as a means for correcting the error.

The present invention solves the above-mentioned conventional problems, and comprises means for directly starting an editing screen for correcting a program causing the error from a screen for notifying an error, It is another object of the present invention to provide a means for performing a series of processing of clearly indicating a corresponding part in an editing screen.

[0014]

According to the present invention, in order to solve the above-mentioned problems and achieve the object, an error notification in the electronic component mounting method of the present invention is based on the type and mounting of the electronic component mounted on the circuit board. Based on the order, a circuit board production method is defined by giving a supply position of an electronic component for efficiently producing a plurality of types and an attribute of the electronic component for mounting the electronic component at a more accurate position. Editing function for creating various programs for controlling the operation of an orthogonal table for positioning a circuit board at an appropriate mounting position from the program and an electronic component holding unit for moving electronic components from a supply position to a mounting position. Conversion function that generates the data of each, the range of parameter values belonging to each program at the time of conversion, the grammatical content of each program, and the combination of programs The integrity verified by, when an error is detected in the program includes a display function for notifying the occurrence point and its contents as an error.

According to the present invention, the operator is assisted so that the program causing the error can be corrected accurately and easily, and the time required for the correction operation is reduced as much as possible. The aim is to improve the operating rate.

FIG. 2 is a flowchart showing a procedure for realizing an error notification according to the embodiment of the present invention. In FIG. 2, as a preparation stage for circuit board production, first, each program and library are edited (step # 1). Next, a combination is created by selecting one program at a time from each program type (step # 2), and these are converted into data for controlling the operation of the apparatus (step # 3). In this step, the evaluation of the value given to the parameter belonging to the program and the syntax analysis of the program are performed at the same time, and the definition range of the parameter value defined in advance and the conformity with the normal format pattern are verified (step # 4). Here, in the combination of programs determined to be errors, the part that directly caused the error is specified (evaluation of the cause) by evaluating the cause of the error and the parameters that link between each program and between the program and the library. In step # 5), an edit screen for the corresponding program or library is started directly from the error display screen so that the location of occurrence can be corrected immediately (step # 6).
