Abstract

PURPOSE:To correct the positioning data of another working process, by converting the positioning data on a certain working process into a designated one. CONSTITUTION:For instance, a working position (d) is slightly shifted in a 1st process and corrected to a working position (f). In such a case, a teaching correction system is applied. That is, a positioning part is first moved to perform a positioning action at the position (f) and the correction data N4 (Xx3, Yy2) is supplied to a control part (correction of the 1st process). If the correction of the positioning data on a 2nd process part is desired simultaneously with the correction of the data on the positioning order N4 of the 1st process part, said corrections are carried out simultaneously. Then the positioning data for correction is transmitted to a control part of the 2nd process part from a control part of the 1st process part. The data N4 is converted into data Xx3 and Yy2 by the data converting functions of both control parts of the 1st and 2nd processes.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for correcting data such as positioning for determining processing positions in a series of processing steps.

Conventional technology Conventional positioning data correction means are based on individual processing steps (
In Figure 1, corrections were made in the two processing steps).
If the same position is being machined separately within a machining line, the positioning data must be corrected in the same way for all machining processes, or the host computer may be used to correct the positioning data.
It was connected to each individual control unit and corrected the positioning data for each machining process.

Problems to be Solved by the Invention However, with such means, when the same position is to be processed in a number of processing steps, it is necessary to correct the positioning data in the same way for the number of processing steps. This method requires several minutes of processing time and is inefficient. Also, if a host computer is used, it is more efficient but expensive.

The present invention solves the above-mentioned conventional drawbacks, and provides a method that allows positioning data to be corrected at low cost, in the time equivalent to one machining process, even if there are a large number of machining processes. It is.

Means for Solving the Problems The method of the present invention for solving the above problems enables communication of positioning data between each machining process, and when the same positioning data is corrected, the positioning data of another machining process is automatically transferred. It has a function that can be corrected.

Operation The present invention converts the positioning data of each processing step into specified positioning data using the data conversion function of the control section through the above-mentioned data communication. As a result, by correcting the positioning data of the machining process, it becomes possible to simultaneously correct the positioning data of other machining processes.

Embodiment Hereinafter, a data correction method according to an embodiment of the present invention will be explained with reference to the drawings.

FIG. 2 shows a processing line in one embodiment, 1
Reference numeral 2 indicates a supply section for a printed circuit board as a workpiece, 2 a first process section for applying adhesive to the printed circuit board, and 3 a second process section for mounting chip components on top of the adhesive applied in the first process section. The process section 4 indicates a storage section for storing printed circuit boards that have been processed. Further, FIG. 3 shows a printed circuit board which is a workpiece, and a-b shows the processing position. The following table shows the positioning data.

Table 1 The data correction method of this embodiment configured as described above will be explained. For example, when the machining position d is slightly shifted in the first process section and is to be corrected to the machining position f, the T-tip method is generally used for this correction. Using this method, the positioning unit that determines the position is moved to the processing position f, and the correction data N 4 (X !3, Y 7
2) is input to the control section. If only the first process section is to be corrected, turn on the data correction start switch for the first process section as before, and use the data conversion function of the control section to convert the correction data N4 to the machining position f, Xxs, Y72. be done. At this time, as shown in Figure 1, if you want to correct the positioning data of the second process section at the same time, turn on the simultaneous correction switch of the first process section and turn on the data correction start switch. The correction positioning data is communicated from the control section of the second process section to the control section of the second process section, and N4 is converted to xx3. The data is converted to Yy2, and the printed circuit board positioning data in Figure 3 is converted to Yy2.
It will look like a table. Of course, it is also possible to simultaneously modify the data of the first process section from the second process section.

Table 2 Effects of the Invention As described above, according to the present invention, by correcting the positioning data of one machining process, the positioning data of other machining processes can be corrected at the same time, increasing the machine operating rate of each machining process. Can be done.
