BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed circuit board (PCB) automatic regulator, and more particularly, to an apparatus and method for adjusting a PCB automatic regulator for automatically adjusting a PCB assembly such as a television, a video, a tape recorder, a monitor, and the like.

Conventional PCB automatic controllers can automatically adjust all of them, but after the automatic adjustment, the power does not come on from the adjusted PCB, or after a certain time, the screen is gradually enlarged and the screen shakes. While checking the problem, it was necessary to adjust the insufficient adjustment and send it to the next process.

Therefore, the present invention was devised to solve the above-mentioned shortcomings, and for this purpose, a CCD camera was used to read and read the screen of the CRT, and to transmit it to an image controller, to compare it with reference data, and to transmit the result to an instrument controller. To make adjustments.

This will be described with reference to the accompanying drawings.

FIG. 1 is a block diagram of the present invention, when a PCB is brought into a measuring unit 40 including a motor driver, an upper mouth, and a lower mouth, it is detected by a sensor and sent to the PLC 30 as an arrival signal, and the PLC 30 is measured. It connects to the controller 20 and reads the screen state displayed on the CRT 50 by the CCD camera 70 to be transmitted to the image controller 60 comparing with the reference value, and the image controller 60 is measured. It is connected to the measuring controller 20 for adjusting the motor and the upper inlet of the upper and the measuring controller 20 is connected to the CRT (50) through the measuring unit 40 and indicates a good (Go) bad (NG) state The controller 10 is configured by connecting the monitor 10 to the instrument controller 20.

2 is an operation sequence of the present invention, when the PCB is brought into the measurement unit 40, the PLC 30 down the upper teeth of the measurement unit 40, raises the lower mouth, and turns on the power (ON), CRT (50) ) To turn on the screen and turn on / off the screen of the CRT 50 in the image controller 60 and to compare the value recognized by the CCD camera 70 with the reference data value, and in the measurement controller 20. The motor rotation direction of (40) is rotated forward (CW) and reverse rotation (CCW) so that the image controller 60 recognizes the value recognized by the CCD camera 70 and the reference data value. ) Signal and pass the bad (NG) signal to the stocker.

Hereinafter, the operation and effects of the present invention will be described with reference to the accompanying drawings.

When the PCB is brought in, the sensor of the measuring unit 40 detects this and sends a PCB arrival signal to the PLC 30.

Therefore, when the PCB arrival signal is received, the PLC 30 advances the RF jack by lowering the upper mouth of the measurement unit 40 and raising the lower mouth.

At this time, since the lower port of the measuring unit 40 is raised and power is applied to the PCB, a screen appears on the jig CRT 50 connected to the measuring unit 40.

Here, the measurement unit 40 and the CRT 50 are connected to each other, and the screen of the CRT 50 is turned on or off depending on whether power is supplied to the PCB.

Therefore, when the screen is displayed on the CRT 50, the CCD camera 7 recognizes the contents of the screen and transmits the contents to the image controller 60.

Therefore, the image controller 60 compares the transmitted data with the reference value, and if the result is within the allowable range, the item is skipped (SKIP) and the next item is compared.

In addition, when the result value compared by the image controller 60 is outside the allowable range, the data transmitted from the CCD camera 70 is compared with the reference value and the result value is transmitted to the measuring instrument controller 20.

At this time, if the value recognized by the CCD camera 70 is larger than the reference value, the image controller 60 transmits an adjustment signal to the measuring controller 20 to rotate the motor of the measuring unit 40 forward (CW), CCD camera 70 When the value recognized by the controller is smaller than the reference value, the image controller 60 transmits an adjustment signal to the instrument controller 20 to reversely rotate the motor of the measurement unit 40 (CCW).

Therefore, the CCD camera 70 recognizes the screen of the CRT 50 and continuously reads the value while the measuring controller 20 lifts and adjusts the motor of the measuring unit 40, and the image controller 60 reads the value of the CCD camera 70. If the data is within the allowable range compared to the reference value, the controller skips (SKIP) and moves on to the next item. If the data is not within the allowable range, the control signal is continuously transmitted to the instrument controller 20.

Therefore, when the adjustment is completed in the instrument controller 20, the Go signal appears on the monitor 10 and sends a completion signal to the PLC (30).

When the PLC 30 receives the completion signal, the PLC 30 reverses the RF jack of the measurement unit 40, lowers the lower inlet, and raises the upper inlet.

In this case, the PLC 30 discharges the high voltage, the low voltage discharge, and the anode voltage together with the completion signal, and turns off the power supply of the PCB. Thus, the power of the CRT 50 is also turned off. Is sent to 30.

Therefore, as the upper teeth of the measuring unit 40 are raised, the PLC 30 operates the conveyor motor to carry out the PCB to the next process.

In addition, if the PCB controller in the instrument controller 20 takes a long time or is not adjusted due to other component defects, the instrument controller 20 indicates the NG signal to the monitor 10 and sends a completion signal to the PLC 30.

Therefore, when the NG signal and the completion signal are transmitted to the PLC 30, the PLC 30 reverses the RF jack of the measuring unit 40, lowers the lower mouth, and raises the upper teeth.

In this case as well, the PLC 30 discharges the high voltage, the low voltage discharge and the anode voltage together with the completion signal, and turns off the power of the PCB. Thus, the power of the CRT 50 is also turned off. Are simultaneously sent to the PLC 30.

Therefore, when the upper teeth of the measuring unit 40 are raised, the PLC 30 drives the conveyor motor to transfer the PCB to the defective NG stocker.

Therefore, when the defective PCB arrives, the sensor is turned on, and the PLC 30 raises the lifter and raises the stocker to load the defective PCB.

As described above, the present invention checks the on state of the CRT screen and the shaking of the screen using the CRT, the CCD camera and the image controller in the post-process after the automatic adjustment of the PCB automatic controller. NG) is a beneficial invention that can be loaded PCB by processing.
