In general, to create optimal production conditions, industrial sites use a variety of equipment to build production lines and perform a series of tasks. In order to build these production lines it is necessary to set up the data with the position information necessary for the performance of the equipment. In particular, a surface mount device (hereinafter referred to as an SMT device) is a device for mounting electronic components on a printed circuit board, and the SMT device is used to mount each electronic component on a printed circuit board at a designated position. Location information of each electronic part should be input.

Equipments that require the setup of work data having the location information of the electronic components required to perform the mounting work include SMD (Surface Mounting Device), AI (Auto Insert Machine), Computer Numerical Control (CNC), and Flying Probe (FP).

Hereinafter, an example of a production line requiring setup of working data including position information of an electronic component in order to perform a series of tasks will be described.

1 is a configuration diagram of a general SMT assembly line.

SMT assembly lines that surface mount electronic components on printed circuit boards consist of a variety of devices.

Specifically, a substrate loader for supplying a printed circuit board to a line, a screen printer for applying solder paste onto a pattern before mounting a component, and a surface mount component are mounted on the substrate. Surface mounter to mount, Reflow Machine to connect the parts and patterns by melting the applied solder paste after mounting all parts on the substrate, and the mounting state It includes a solder inspection, a sorter for sorting a printed circuit board on which surface mounting is completed, and an unloader for removing the sorted board from a line.

Each device constituting the SMT assembly line is connected through a conveyor, and the printed circuit board that has completed the work in each device is transferred to the next device through the conveyor.

The surface mounter is a device that mounts electronic components on a printed circuit board, and the various electronic components such as semiconductor devices come from the component supplier. When supplied, the electronic components are transferred to the mounting position of the printed circuit board and then mounted at the designated position on the printed circuit board.

Each device constituting such an SMT assembly line is not only used by the equipment of any one manufacturer, but equipment of different manufacturers may be used in consideration of various matters.

The SMT assembly lines are not composed of only one, but a plurality of assembly lines are constructed and optimized according to the amount of work, work speed, and work content.

These SMT assembly lines need to set up work data to control the operation of each piece of equipment before the printed circuit board is put into the SMT assembly line.

The work data includes various information, such as X position, Y position, Rotation, Reference ID, Part Number, etc., including a character representing the position information of the electronic component. Each of the characters included in the work data includes not only a factor indicating the position information of the electronic component, but also other information.

The work data used in the conventional SMT assembly line is different in file format for each device constituting the SMT assembly line, and even if the same equipment is different for each manufacturer, the file format is different according to the orderer's request. When something needs to be changed or when the operating conditions of an SMT assembly line are minimized, all work must be stopped and new work data generated while spending a lot of time.

For example, if an accumulation occurs in one assembly line due to a difference in processing speed or a difference in work contents while performing each operation with the SMT assembly lines of A, B and C, New set up of work data on the assembly line. For this purpose, the generation of working data must be done from the beginning.

In addition, even though there are many matching parts among the necessary work data among the equipment of a, b, c, and d constituting the A line, it is possible to generate respective work data for each equipment of a, b, c, and d. do.

This is caused by the lack of standardization of job data generation. This is because job data is generated by different file formats for each manufacturer and device. In particular, since SMT devices are represented by different codes according to their manufacturers, a lot of time and work are required for a manufacturer to use the work data inputted in one SMT device in another SMT device. There is.

This problem makes efficient line management and production management difficult.

Accordingly, an object of the present invention is to solve the problems of the prior art as described above, the operation data generation between the equipment for each manufacturer having a different file format or the equipment constituting one line is made by each operation This is to solve the problem of increasing the time required to set up the equipment.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of a file format converting apparatus and method for working data including position information of an electronic component according to the present invention will be described in detail with reference to the accompanying drawings.

Of these drawings, as shown in Figure 4, the file format conversion apparatus of the work data used in the equipment according to the present invention, the operator's computer to the equipment 100 to perform a series of operations according to the input work data Display for displaying the interface unit 41 for connection, an extraction unit 43 for extracting information data necessary for driving the equipment from the work data, and the information data extracted by the extraction unit 43. Part 45; And a controller 42 for controlling these operations.

First, the file format converting apparatus of the present invention is provided with an interface unit 41. The interface unit 41 serves to connect the file format converter and the device 100 so that a work data file can be transferred between the file format converter and the device 100.

The apparatus 100 connected to the file format converting apparatus may be applied in various ways. For example, various apparatuses such as a surface mount (SMT) apparatus, an auto insert apparatus, and a computer numerical control (CNC) apparatus may be used. have. The equipment 100 stores information necessary for each operation in ASCII code. For example, the information data necessary for the operation of the equipment 100 may include X position information, Y position information, Y position information, rotation information, reference ID, and part number. Number) etc. can be mentioned.

In more detail, the X position information and the Y position information relate to the position of the substrate on which the device for surface mounting is to be mounted. This may be represented as a coordinate with one edge of the substrate as an origin, and may be composed of a combination of numbers. For example, the Sangik X position information and Y position information may be represented as 63.35, 93.35, 80.05, ..., and the like.

The rotation information relates to the rotation position when the device is mounted on the substrate. This determines the orientation when the device is seated on the substrate. For example, the rotation information represents an angle, and may be represented by any number within the range of -360 to 360. However, the rotation information is generally composed of any one of the numbers 0, 90, 180, 270.

In addition, the reference ID is information for reference when identifying a device mounted on the substrate. This is to identify the device to be located in the X position information, Y position information, and rotation information, which may be represented by a combination of letters and numbers. For example, the reference ID may be composed of CI1, BI1, BT2, ....

The part number is information on a type of element mounted on the substrate. This indicates which component should be mounted on the substrate. For example, the part number may be composed of CL21B44KBNC, CL10B104KONC, ....

When the work data is substantially opened, the above items are randomly arranged without any form. In other words, the X position information, the Y position information, the rotation information, the reference ID, and the part number are arranged so that the operator cannot identify the work data.

However, each information data constituting the work data of the ASCII code is prepared to be separated by delimiters. For example, it consists of X position information, delimiter, Y position information, delimiter, reference ID, delimiter, and part number.

Therefore, if the delimiter can be extracted, it is easy to extract each piece of information data, and as a result, the information data can be easily sorted by the operator. In order to extract the delimiter, first, the determination of which character the delimiter is composed of must be preceded.

The character may be represented in ASCII code from 0 to 512. In other words, the character may generally be composed of ordinary characters, special characters, and extended characters.

The common characters are a, b, c, ..., x, y, z and A, B, C, ..., X, Y, Z and 0, 1, 2, ..., 8, 9 It is composed. And, the special character is composed of a space, +,-, /, ~, .... On the other hand, the extension is composed of a, b, c, d, .... This is specified as a number of 0 to 512 on the above ASCII code.

On the other hand, the characters used as delimiters in the job data, the general characters and extended characters are generally not used. This is to avoid confusion because the general and extended characters are used as the characters constituting the information data.

That is, only special characters may be used as the delimiter. Therefore, in order to extract the delimiter, extraction of the special character usable as the delimiter among the characters is preceded. This process is performed by the extraction unit 43 of the file format conversion apparatus of the present invention.

The extracting unit 43 serves to extract information data necessary for a job from the job data. That is, the extraction unit 43 classifies, extracts and organizes the information data among the work data.

More specifically, the extracting unit 43 firstly comprises a delimiter extracting unit 43a for extracting delimiters from the work data, and each piece of information data constituting the work data by extracting the delimiters. And a row column extracting unit 43b for sorting the matrix into a matrix, and a data extracting unit 44 for classifying the information data corresponding to each matrix from the work data arranged in the matrix.

First, the delimiter extracting unit 43a serves to extract a delimiter for distinguishing each piece of information data from the unorganized work data as described above.

In more detail, the frequency of each character is calculated in the work data. This results in a frequency result for each character.

When the result value of the frequency for each character comes out, only the special character is extracted from the character. Then, by comparing the frequency of each of the special characters to extract a special character having the highest frequency. The special character having the highest frequency is treated as a delimiter.

This is because the characters generally used as delimiters among the characters constituting the work data are special characters, and the highest frequency among the special characters is delimiters.

For example, assuming that the job data consists of 00, 11, 33, 44, ..., 00, 11, 33, 44 can not be used as delimiter as a normal character, only ',' as delimiter Can be used. This is the reason as described above. Therefore, when determining the highest frequency among the remaining characters (special characters), ',' is extracted and ',' characters are treated as delimiters.

Meanwhile, a row column extracting unit 43b is provided in the extracting unit. The row column extracting unit 43b sorts the work data from which the delimiter is extracted into a matrix. If there are various methods, for example, the following method can be used.

First, we extract the carriage return character to clean up the rows. The carriage return character is generally 13 in ASCII code. The carriage return character sets a carriage line from the carriage return character to the next carriage return character before the next carriage return character. Then, the rows (rows) of the information data constituting the work data are arranged.

The row column extracting unit 43b sorts the delimiters. Then, the columns (columns) of the respective information data in which the rows (rows) are aligned are arranged so that each information data is arranged while constituting each cell in a predetermined matrix.

On the other hand, the extraction unit 43 is provided with a data extraction unit 44. The data extracting unit 44 serves to extract what information data of each column represents in the working data among the working data arranged in a matrix by the row column extracting unit 43b.

In other words, the data extracting unit 44 extracts any one of the X position information, the Y position information, the rotation information, the reference ID, and the part number.

The information data consisting of the characters is formed of a combination of various characters except for the special characters, and the X position information and the Y position information are composed only of numbers. This is because one edge of the substrate is represented by coordinates.

If the percentage of numbers in each character exceeds 70% in the information data consisting only of numbers in any row (row) of the information data, the data extracting unit judges the information data as either X position information or Y position information.

The data extractor 44 extracts rotation information. Since the characters constituting the rotation information are composed of any one of 0, 90, 180, and 270, if the percentage of whether the character corresponds to the character exceeds 70%, the data extraction unit 44 rotates the information data. Judging by

The data extractor 44 extracts a reference ID. The reference ID, if the configuration is more than 70% of the percentage of the combination of the first character and the last character ending with the number is more than 70%, the data extraction unit 44 determines the information data as the reference ID. .

In addition, the data extractor 44 extracts a part number. The part number describes the type and characteristic of the part, and the length of the character is longer than that of other information data. That is, if the percentage of whether the length of the character is the longest in each row forming the work data exceeds 70%, the data extraction section 44 determines the information data as the part number.

On the other hand, the file format converter is provided with a display unit 45. The display unit 45 serves to indicate to the operator that each sorted information data extracted by the data extraction unit 44.

The file format converter is provided with a control unit 42. The controller 42 controls each operation occurring in the above-described file format converter.

Hereinafter, the operation of the file format converting apparatus and the method of the work data including the positional information of the electronic component according to the present invention having the above-described configuration will be described in detail.

First, the interface unit 41 of the file format converter is coupled to the interface of the equipment to convert the work data. When the file format converter is driven, the job data of the device 100 is transmitted through the interface unit 41.

The control unit 42 of the file format converting device opens the work data which is the ASCII code, and the extracting unit 43 organizes the work data so that the operator can easily understand it. The process of the extracting unit 43 to organize the work data will be described in detail below.

First, the row column extraction unit 43b of the extraction unit 43 determines the number of carriage return characters of the operation data to determine the number of lines of the operation data (S501).

The delimiter extracting unit 43a extracts a delimiter from the work data (S502). Of course, the process of determining the number of carriage return characters by the row column extracting unit 43b may be followed by the process of extracting the delimiters from the work data by the delimiter extracting unit 43a.

The delimiter extracting unit 43a calculates the frequency of each character of the work data. When the result value for the frequency of each character of the work data comes out, only the special character is extracted from the character.

A special character having the highest frequency is extracted by comparing the frequency of each of the special characters. The special character having the extracted highest frequency is treated as a delimiter.

When the extraction of the delimiter is completed, the carriage return character is extracted by the row column extraction unit 43b. As described above, the carriage return character may already be extracted.

When the carriage return character is extracted, the carriage return is arranged in one line, that is, the beginning of the line (row). When the arrangement of the rows (rows) of the work data is completed, the columns of the respective information data separated by the delimiter in each row are arranged (S503 and S504). A process of arranging columns of information data arranged in random order in each of the above rows will be described in detail below.

A process of arranging columns of information data will be described on the assumption that the work data of the rows separated by the carriage return character is, for example, BI1, 63.35, 93.35, -90, CL21B474KBNC.

First, the delimiter in the work data is a special character having the highest frequency, and thus becomes ','. That is, the work data is divided into five pieces of information data divided by ',' which are delimiters.

It can be seen that the information data is composed of X position information, Y position information, rotation information, reference ID, and part number. First, the X position information and the Y position information are extracted.

The data extracting unit 44 of the extracting unit 43 extracts the information data consisting only of numbers among the information data, that is, the information data with the percentage of the number exceeding 70% among the respective information data (S506). As the information data extracted by the above process can be seen in the above example, two values of 63.35 and 93.35 are extracted.

The two pieces of information data of 63.35 and 93.35 constitute X position information and Y position information, respectively. Particularly, any one of the above 63.35 and 93.35 is X position information and the other is Y position information, which should be arbitrarily distinguished by the operator, but generally the first information data is X position information, and the next arrangement corresponds to Y position information. (S507).

When the extraction of the X position information and the Y position information is completed, the data extraction unit 44 extracts the rotation information. The data extracting unit 44 extracts the information data of which the percentage of any one of 0, 90, 180, and 270 of the information data exceeds 70%. The information data extracted by the above process is -90 as can be seen in the above example, and the information data is set as rotation information (S508).

When the extraction of the X position information, the Y position information, and the rotation information is completed, the data extractor 44 extracts a reference ID. The data extracting unit 44 extracts information data having a percentage of 70% or more, which forms a combination in which the remaining characters except for numbers start with the first character and end with the number among the respective working data.

That is, when the first character of the information data starts with a character except for a number and the last character ends with a number, when the information data of BI1 is extracted, the data extracting unit 44 refers to the information data for BI1 as a reference ID. (S509).

After extracting the reference ID, the remaining information data is CL21B474KBNC, which is set to an item corresponding to the part number. Of course, the data extracting unit 44 may set the information data corresponding to the part number to 70% or more as the percentage of whether the length of the character is the longest among the information data (S510). .

When the job data arranged in each row (row) is arranged in the same manner as described above, when the job data is arranged in a form having a predetermined matrix, the controller 42 displays the job data arranged in the matrix. It is represented through (S511).

In this way, the data of unstandardized files are opened to organize necessary information data and standardized so that the work data stored in each equipment can be used in other equipment.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. It is self-evident.
