Description

Coordinate input device and its control method

In particular, the present invention relates to a coordinate input device for a coordinate measuring machine for reading numerical data from a database of parts to be mounted on a printed circuit board and generating numerical control data and CAC data.

In the production of electronic products, inserting parts on printed circuit boards has long been an automation challenge and is now commonplace. The automatic insertion process is as follows.

(1) First, create an electric circuit diagram.

(2) A pattern of the printed circuit board is made based on the electric circuit diagram.

(3) A printed circuit board is manufactured in a pattern of a printed circuit board, and the component data for manufacturing and assembling is prepared.

(4) Using the pattern of the printed board, information on the mounting position, mounting parts, mounting direction, etc. of the parts is extracted and converted into numerical control data suitable for each equipment.

(5) The numerical control data is input to the automatic inserter, and the prepared printed board and necessary parts are supplied to perform automatic insertion to assemble the printed board.

(6) The printed board, which has been automatically inserted, is soldered and assembled using an automatic soldering machine to complete the printed board.

Here, circuit diagram and printed circuit board pattern are implemented using CAD and can be computerized, and numerical control data can be extracted by converting computerized data. However, in the case where a printed circuit board is to be further fabricated or assembled, or when there is no information about the printed circuit board pattern and only an actual printed circuit board exists, a computerized operation is not possible for extracting the numerical control data. So that it is troublesome to write numerical control data.

According to an aspect of the present invention, there is provided an apparatus comprising: a scanner for reading an image of a printed board and converting the image to digital data; a memory unit for receiving and storing digital data from the scanner; A monitor for inputting image data of the printed board and displaying the received image data on a screen, input means for receiving data and commands from a user, inputting means for storing information of a part to be inserted into the printed board, A hall information database for storing hall information of the printed board; a hall information database for extracting hall information from the image data of the printed board from the scanner, Reads the data from the part information database, And a control unit for calculating and storing the numerical control data according to the format of each equipment.

A method according to the present invention includes the steps of receiving image data of a printed board through a scanner to monitor and displaying the image data, extracting hall information using an image recognition algorithm, Calculating a relative coordinate value of each hole around the reference hole of the corresponding block and inputting the part number of the part to be inserted in the hole selected by the user through the input means, Retrieving the unique number of the part and the name of the equipment to be installed, sorting the equipment according to the type of each part, calculating the numerical control data according to the format of each equipment, and storing the data in the database.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing a configuration of a mounting coordinate input device according to the present invention.

The apparatus according to the present invention comprises a scanner 3 for reading an image of a printed board and converting the read image into digital data, a memory 2 for receiving and storing digital data from the scanner 3, A monitor 4 for receiving image data of the printed board and for displaying data on the screen, input means 5 for receiving data and commands from a user or the like, A hole information database (7) for storing hole information of the printed board; and a control unit (7) for reading out the image of the printed board from the scanner (3) Extracts the hole information from the data, inputs the part number of the part to be inserted in the hole selected by the user, reads the data from the part information database, Retrieve the equipment, consists of a control unit (1) for storing and calculating the numerical control data according to the format of each device. The operation and effect of the present invention will be described below.

FIG. 2 is a flow chart showing a coordinate input method for a self-aligner according to the present invention.

In step 201, the image data of the printed board is inputted through the scanner and displayed on the monitor 4 as shown in FIG. In step 202, hall information is extracted using an image recognition algorithm. In step 203, the reference direction is set by using two reference holes inputted by the user through the number of inputs (5). In step 204, the relative coordinate value of each hole is calculated based on the reference hole of the corresponding block.

The user inputs the part number of the part to be inserted into the hole selected by the user through the mouse 6 and the input means 5 (e.g., keyboard, etc.) from the image of the printed board displayed on the monitor 4 in step 205. The part number of the part to be inserted receives the part number inputted by the user through the input unit 5. In step 206, data is read from the part information database 8 based on the part number of the part input through the input unit 5, and the unique number of the part and the equipment name are searched. In step 207, it is judged whether or not a part is allocated to all the holes. If no part is assigned to all the holes, the process of step 205 is repeated to input the part number of the part to be inserted in the hole newly selected by the user, and the process below is repeated.

If all the holes are assigned to the parts, the mounting equipment is classified according to the type of each component in step 208 and the numerical control data is calculated according to the format of each equipment. The data calculated in step 209 is stored in the database and the present program is terminated.

As described above, according to the present invention, since the hall position is automatically retrieved by using the visual recognition algorithm, the coordinates of the hole can be accurately and quickly extracted, and the hall information and the part information are managed by the computer, And can reduce the burden of inputting part information and mounting equipment.

SUMMARY OF THE INVENTION An object of the present invention is to provide a coordinate input device and a control method thereof for reading a part number only from a database of parts to be mounted on a printed circuit board to create numerical control data and CAD data.
