The present invention provides an error location for an error occurring during chip mounting in a chip component automatic mounting system for automatically mounting a chip on a printed circuit board (PCB) of the chip component automatic mounting apparatus displaying an error processing method on a CRT. It relates to an error handling method.

If an error occurs when various chips are mounted on a printed circuit board as a conventional chip part automatic mounting device, an error message sounds and an error message that appears on the CRT screen is displayed as shown in FIG. 5, for example, XY NOT ORIGIN 01. In this example, it is assumed that the X axis is not in the ORIGIN state.

Therefore, if an error occurs during the operation of the chip parts automounter, the operator presses the RESET switch on the KEY panel to stop the beeping, removes the fault as described in the manual, and starts the operation again. Since only error codes that signal errors (eg, machine work error, NC data error, system error, etc.) are displayed as a beep, error recovery is possible only when the operator manually finds the manual and corrects the cause of the error. will be.

However, even an experienced worker did not know a myriad of error codes and, after checking the error codes generated by referring to the manual, took action, and it was inefficient because it took a lot of time to deal with errors.

Accordingly, an object of the present invention is to solve the above problems, and an object of the present invention is to display an error code on a CRT screen when an error occurs during the operation of an automatic chip component mounting device, and to return the error as well as the position where the error occurs by processing the graphics. It is to provide an error handling method of the chip component automatic mounting machine displayed on the CRT screen.

This will be described with reference to the accompanying drawings.

1 is a block diagram of an error processing system according to the present invention. The main controller 10 recognizes an error detected by a sensor and controls an entire system, and an interface for inputting and outputting data to the main controller 10. 20, a user interface 30 for managing NC data (OPERATION, PARTS, MOUNT, etc.) and operational data of the chip component auto-mounter through the interface 20, and the main through the interface 20. Receives a control command from the controller 10 and receives the input from the user interface 30 and the motor controller 60 for driving the motor 70 to operate each device (eg, XY table) for mounting the chip. Outputting CRT 50 displaying various management data (error type, cause processing, return method, etc.) on the screen, NC data input by the operator and working data on the interface 20 and the user interface 30It constitutes a panel (40).

Hereinafter will be described the operation and effect of the present invention.

For example, if an error occurs such that the XY table of the chip parts automounter overruns the origin, the sensor detects this (assuming that the sensor detects an abnormal cause of the chip parts autoloader). The main controller 10 recognizes this by outputting a signal to the main controller 10. The main controller 10 controls the recognized signal using an internal program to find a corresponding error type (for example, XY NOT ORIGIN) and transmits data through the interface 20 to notify the user interface 30 of the occurrence of an error. Send the error type and return method.

The user interface 30 shows the error type (eg, XY NOT ORIGIN), which is the data input from the main controller 10, and the abnormal cause and return method according to the CRT 50 as shown in FIG. Displays an error message screen on the screen.

The error message screen includes an error type display area 51 for displaying an error type, an error cause display area 52 for displaying an error cause, an error positioning key area 53, a return method key area 54, and a cancel key area. It consists of 55.

When you place the cursor on the error positioning key area 53 and click the mouse or press the enter key of the key panel 40, the error positioning screen is displayed as shown in FIG. 2 (b). The displayed error value display area 56, return method key area 57 and cancel key area 58 are displayed.

Here, when the return method key area 57 is selected, the screen shown in FIG. 2 (c) is displayed. When the cancel key area 58 is selected, the screen shown in FIG. 2 (a) is displayed again.

To find out how to remove the cause of the abnormality, place the cursor in the return method key area 54 and click the mouse or press the enter key of the key panel 40 to place the cursor in FIG. Pressing or pressing the Enter key on the key panel 4 displays the error return method screen as shown in FIG. 2 (c), which displays the error return method display area 59 and the next page key area 61. It consists of a page key area 62 and a cancel key area 63. When the next page key area 61 is selected, the next page is displayed on the screen displaying the return method. When the previous screen key area 62 is selected, the previous page is displayed on the screen displaying the return method. In addition, when the cancel key region 63 is selected, the error message screen shown in FIG. 2A is displayed.

Therefore, when the screen displaying the error return method is operated and displayed as it is displayed, the main controller 10 issues a command to the motor controller 60 to drive the motor 70 properly, and assembles the XY table so as to come to the origin. Eliminate the cause of abnormalities.

3 is a flowchart showing an error processing method according to the present invention.

In step S31, it is determined whether an error has occurred by receiving a signal detected from a sensor installed in each part of the chip component automatic mounting machine. In step S32, if an error has been detected, an error message screen is displayed on the CRT of the user interface 30 as shown in FIG. As described above, the error message screen includes an error type display area 51 for displaying an error type, an error cause display area 52 for displaying an error cause, an error position confirmation key area 53, and a return method key area 54 ) And a cancel key area 55.

In step S33 and step S34, it is determined which key area is selected from the error position confirmation key area 53, the return method key area 54 and the cancel key area 55 displayed on the error message screen. When the cancel key area 55 is selected, the present program ends, and when the error location key area 53 is selected, in step S35, the error location screen is displayed as shown in FIG. In step S36, it is determined which key area is selected from the return method key area 54 and the cancel key area 55 shown in the error position confirmation screen. If the return method key area is selected, the process proceeds to step S37. If the cancel key area is selected, the process returns to step S31.

On the other hand, if it is determined in step S34 that the return method key area 54 is selected, the flow advances to step S37 to display the error return method screen on the CRT of the user interface 30 as shown in FIG. . In step S38, it is determined which key is selected from the next page key area 61, previous page key area 62 and cancel key area 63 of the error return method screen. If the next page key area 62 has been selected, in step S39, the next screen showing the error return method is displayed and step S38 is repeated. If the previous page key area 62 has been selected, in step S40, the previous screen showing the error return method is displayed and step S38 is repeated.

4 is a flowchart showing the overall operation of the chip component automatic apparatus to which the present invention is applied. When power is applied, the main controller 10 reads and initializes a program from a memory (not shown) and determines which mode is selected. When the automatic mounting mode is selected, the mounting process is performed by the automatic mounting software program, and when an error occurs, the error handling process is performed as previously occurred.

In addition, when selected during manual operation, the return operation for returning each device (eg XY, table, reel shaft, etc.) of the chip parts automounter to the origin and the inching to move each device by the designated (input) value. There is operation.

When the return operation is selected in the user interface 30 during the manual operation, each device surface and the home state are displayed on the screen of the CRT 50.

At this time, the devices that are in the home state are marked with * (star), and the other equipment does not show any indication.

Here, each device is returned by moving the cursor of the CRT 50 to the device to be returned to the origin and pressing the MOVE key of the key panel 40.

Similarly, when the inching operation is selected in the user interface 30, each device name and origin state are displayed on the screen of the CRT 50.

In this case, after inputting data to the user interface 30 as much as a numerical value to be moved, the device moves at a pitch interval by pressing the MOVE key of the key panel 40.

In addition, TEACH is a menu used for managing and modifying various data, and provides information on operation data, operation, parts, and mount data, which largely indicate equipment operation time, number of mounting PCBs, and error information. It shows the NC data information and the parts library information used when modifying and information on each parts data.

As described above, according to the present invention, when an error is detected during the operation of an automatic chip component mounting machine, the main controller controls the internal program and graphically processes the error code to display the position and return method of the error on the CRT screen. You can easily modify the expected work convenience.
