Description

FIELD OF THE INVENTION [0001] The present invention relates to a PCB testing device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for inspecting a face pattern, and more particularly, to a device for inspecting a face pattern by optically detecting a pattern of a face, Which can be easily and clearly carried out by the user.

In recent years, PCBs (Printed Circuit Boards) have been used in computers, televisions, mobile phones and various other industrial equipments. Such a PCB has been spread in a form that is flexible in size, small in size, In the case of such a flexible PCB, since the circuit is designed on the board with a limited size, the structure of the circuit formed on the PCB is very complicated and the line width is formed to be very thin.

For this reason, it is necessary to check whether the circuit pattern formed on the PCB is the same as the design before mounting various components on the PCB, It is customary to perform a full screening test and then use only an abnormal body fat.

As described above, a tester used for checking whether there is an abnormality in whether or not a pattern formed on the PCB is maintained in the same state as the design uses an optical inspection machine (AOI; Automated Optical Inspection) And supplying the sorted file to the tester, and discharging the scanned file to the rack for discharging.

Such a device for inspecting a pattern of a pattern 1 has been conventionally developed and used, and a typical example will be described with reference to FIG.

(50) for rotating the PCB to be tested by 180 degrees, a PCB (50) directly from the elevating unit (40) when the first box is mounted on the first box, A PCB 30 which is attracted to the PCB 30 and which ascends and ascends by absorbing the PCB rotated 180 degrees by the rotation unit 50 when the PCB 50 is a back surface; A cleaning unit 60 for removing the substance from the surface of the PCB inserted into the transfer unit 20, and first and second adsorption devices for adsorbing the PCB, And a rotation inserting portion 10 which is provided in the opposite direction and feeds and takes out the PCB to the PCB inspecting device.

Registration of Utility Model No. 20 - 0129609 - 0000 Patent No. 10 - 0410796 - 0000 Patent No. 10 - 0683265 - 0000

In the conventional technology as described above, since the apparatus has the parallel and multi-layer structure, it is possible to supply the inspection fee to the inspection device at a glance, and to discharge the inspected user fee to the discharging rack, .

As a result, the process of supplying and discharging the PCB can not be performed in a straight line but it must be rotated and changed its direction. Therefore, it takes a longer time to supply the PCB to the inspection device and discharge it from the inspection device. Which causes deterioration of inspection efficiency.

Especially, it is necessary to arrange the inspection expenses for supplying and discharging the equipment cost to be supplied to the supply rack, to supply the sorted PCB to the inspection unit, and to load the inspection unit's fee to the discharge rack at once, It is complicated and difficult in terms of control.

That is, when the user moves the feeder in the feed direction, the movement of the feeder from the alignment position to the position of the inspector is stopped and is in the standby state. When moving the feeder from the inspector to the discharge rack, It is troublesome to add an operation to rotate them so as not to interfere with each other.

As described above, since the time required for supplying and discharging the PCB increases, it is difficult to perform the inspection efficiently, and at the same time, it is associated with other equipment arranged before and after the inspection device, which adversely affects the entire process of the PCB It will be self-evident.

In addition, since the supply device and the inspection device can not be arranged in a straight line, they are arranged in a parallel state or a shape or a shape, so that the installation space is increased and the work movement line becomes longer. And it takes a lot of time.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide an apparatus and a method for inspecting a frame, comprising: a PCB feeder for loading a PCB to be tested in a frame; an aligner for aligning PCBs to be tested, And a control unit for controlling the operation of the control unit in such a manner as to sequentially feed the inspected object to be inspected to the outside of the frame, And a feeding unit for feeding the inspection unit to feed the inspection unit with the inspection unit and the inspection unit to transport the inspection unit to the inspection unit.

By feeding and sorting the PCB to be inspected to the aligner and tester, and transferring (discharging) the PCB to the inspection machine and the PCB discharge by the reciprocating movement in the longitudinal direction, the control can be simplified and the operation speed can be improved Thereby improving the overall speed of the PCB line, thereby achieving an objective of performing an efficient operation.

In the present invention, a feeder for feeding a test subject to be inspected and an aligner for aligning the fed-in feed from the feeder, a tester, and a discharge stand for discharging the inspected food expenses are arranged in a straight line, So that the operation speed required for inspection can be greatly improved while reducing installation space.

It is possible to simplify the control algorithm by simplifying the control algorithm by arranging the supply and discharge of the PCB in a straight line so as to simplify the overall structure and shorten the cost and time required for the installation cost and maintenance.
