Abstract

PURPOSE:To prepare a mounting program which does not relay on the fitting method of electronic components to each device so as to make the mounting program commonly usable by directly commanding the names of electronic components commonly used for each device by using a component name command. CONSTITUTION:In a program analyzing section, the second character analyzing section 11 confirms whethere or not the second character of a command, namely, feeder number command or component name command from a character analyzing section 91 is a numeral code. When the second character is the numeral code, the section 11 discriminates that the command is the feeder number command and outputs the command to a feeder number command analyzing section 94. When the second character is not the numeral code, on the other hand, the section 11 discriminates that the character is a component name command and outputs the command to a component name command analyzing section 12. The section 12 retrieves a component data table 71a for the same component name as that of the component name command and outputs a relevant feeder number and component data to an one-step buffer 95 after selection. Therefore, a mounting program can be commonly used.

Mounting position command analysis section 93, feeder number command analysis section 94
Output to. The step number command analysis section 92 analyzes the input step number command 61, and the mounting position command analysis section 93 analyzes the input mounting position command 62. The feeder number command analysis unit 94 selects the corresponding part data 73 from the parts data table 71 according to the feeder number commanded by the input feeder number command 63, and transfers it to the one-step buffer 95. This one step buffer 95
are the step number command analysis section 92 and the mounting position command analysis section 9
When a mounting command for one step is input from the feeder number command analysis section 94, this mounting command is output to the mounting command storage section 85.

[0007]

[Problems to be Solved by the Invention] In recent years, with the generalization of DNC systems using the above-mentioned management computers, there has been a strong demand for common mounting programs for a plurality of electronic component mounting apparatuses. However, in the mounting program in the conventional electronic component mounting apparatus described above, the electronic component to be mounted is designated by a feeder number command that designates the feeder number to which the desired electronic component is mounted. Therefore, since the mounting program depends on how electronic components are mounted in each electronic component mounting apparatus, there is a problem in that it is difficult to standardize the mounting program.

[0008] The present invention was made to solve the problems of the conventional devices as described above, and its purpose is to standardize the mounting program.

[0009]

[Means for Solving the Problems] An electronic component mounting apparatus according to the present invention provides a component name command for specifying the electronic component in the mounting program, and a program analysis method that obtains the component name by analyzing the mounting program. and component unit selection means for selecting a component supply unit that supplies an electronic component having the component name from a preset component data table according to the component name obtained by the program analysis device, The method is characterized in that electronic components are taken out from a component supply unit and mounted on the printed circuit board.

0010

[Operation] The electronic component mounting device of the present invention can control how electronic components are mounted in each electronic component mounting device by directly instructing the names of electronic components commonly used in each device using a component name command. It becomes possible to create independent mounting programs, and it is possible to standardize mounting programs for a plurality of electronic component mounting apparatuses.

[0011]

[Embodiment] An embodiment of the present invention will be explained based on the drawings. FIG. 1 shows a block diagram of a program analysis section 83 according to the present invention, and the same parts as those of the conventional device shown in FIG. In Figure 1,
11 is a second character analysis section, 12 is a component name command analysis section, 71
a is a parts data table, and the part inside the broken line containing these is the part added for the device of this invention.

FIG. 2 is a flowchart explaining the operation.
FIG. 3 shows a mounting program, which is composed of a step number command 61, a mounting position command 62, and a component name command 31. The component name command 31 is composed of a leading P code and a component name.

FIG. 4 shows the data structure of the parts data table 71a, in which feeder number 72, parts data 73
, component name 41, and the component name indicates the name of the electronic component attached to each feeder.

Next, the operation will be explained with reference to the flowchart of FIG. 2 showing the operation of the second character analysis section 11. The second character analysis unit 11 checks whether the second character (the next character after P) of the command input from the character analysis unit 91, the feeder number command 63, or the part name command 31 is a numeric code (step ST
2-1), this second character is a numeric code, that is, YES
If so, the command is determined to be the feeder number command 63 and output to the feeder number command analysis section 94 (step ST2-2
). If it is not a numeric code, that is, if it is NO, the command is determined to be a parts name command 31 and the parts name command analysis unit 12
(step ST2-3). This component name command analysis unit 12 extracts the component name command 3 from the component data table 71a.
A search is made for a part name that is the same as the part name of No. 1, and the corresponding feeder number 72 and part data 73 are selected and output to the one-step buffer 95. Note that the other operations are the same as those of the conventional device shown in FIG. 9, so repeated explanation will be omitted.

[0015]

As described above, according to the present invention, by issuing a component name command specifying the electronic component to be mounted on the mounting program, the mounting program can be shared among multiple electronic component mounting apparatuses. This has the advantage that it is possible to measure the wearer's performance and also use a conventional mounting program.
