Description

PCB자동검사시스템의 PCB자동정렬장치PCB automatic alignment device of PCB automatic inspection system

본 고안은 PCB자동검사시스템의 PCB자동정렬장치에 관한 것으로서 더욱 상세하게는 PCB를 검사하기 전단계에서 부작위로 공급된 PCB를 자동으로 정렬하여주는 장치에 관한 것이다.The present invention relates to a PCB automatic alignment device of the automatic PCB inspection system, and more particularly, to a device for automatically aligning the PCB supplied by chance in the step before the PCB inspection.

PCB자동검사시스템은 PCB상에 인쇄된 패턴이 정확하게 되어있는지의 여부를 검색하여 양호와 불량을 선별하여 주는 장치이다.The PCB automatic inspection system is a device that sorts good and bad by searching whether the printed pattern on the PCB is correct.

이러한 PCB자동검사시스템(20)은 제1도에 도시된 바와같이 검사기(10)와 검사기(10)의 전방에 위치하여 PCB를 공급하여 주는 공급플레이트(11), 공급플레이트(11)의 양 측방으로 배열되어 검사함 PCB를 적층하는 공급슈트(12)와 공급슈트(12)상에 무작의로 적재되는 PCB상간에 마찰에 의한 손상을 방지하기 위한 간지를 공급하여주는 간지공급대(13), 상기 공급슈트(12)상의 PCB를 공급받아 정렬시키는 정렬플레이트(14), 검사기(10)에서 검사가 완료된 PCB부를 적재하는 수납플레이트(15)로 대분하여 구성이 된다.The automatic PCB inspection system 20 is located in front of the inspector 10 and the inspector 10, as shown in FIG. 1, the supply plate 11 for supplying the PCB, both sides of the supply plate 11 Arrangement check box arranged between the supply chute (12) for stacking the PCB and the intermittent paper supplying table (13) for supplying interlayer paper for preventing damage due to friction between the randomly loaded PCB on the supply chute 12, The arrangement plate 14 for receiving and aligning the PCB on the supply chute 12 is arranged, and the receiving plate 15 for loading the PCB portion that has been inspected in the inspector 10.

상기와 같은 PCB자동검사시스템에서 종래에는 검사를 위한 PCB를 정열시키기 위해서는 작업자가 일일이 수작업으로 정렬플레이트상에 위치를 결성시켜주거나, 실린더나 로보트등을 이용하여 PCB를 정렬하여 왔었다.Conventionally, in order to align the PCB for inspection in the PCB automatic inspection system as described above, the operator has manually arranged the position on the alignment plate by hand, or aligned the PCB using a cylinder or a robot.

상기와 같이 PCB를 수작업으로 정렬하고자 할 경우에는 작업의 효율성이 저하되고 실린더나 로보트를 이용하여 PCB를 정령하고자 할 경우에는 PCB가 얇은 관계로 절곡되는 현상이 다발되어 PCB의 패턴을 검사하기 이전에 불량으로 처리가 되는 문제점이 있다.As described above, if the PCB is to be manually aligned, the efficiency of the work is reduced. If the PCB is to be spirited using a cylinder or a robot, the PCB is bent in a thin relationship. There is a problem that the processing is bad.

뿐만 아니라, 정렬플레이트의 크기가 PCB와 거의 동일한 규격으로 되어있기 때문에 실린더나 로보트에 고정된 이송치구의 작동성이 저하됨으로서 실질적으로 PCB를 정렬하는데 상당한 문제점들이 있었다.In addition, since the size of the alignment plate is almost the same size as the PCB, there is a significant problem in actually aligning the PCB as the operability of the transfer tool fixed to the cylinder or the robot is lowered.

이에 본 고안에서는 상기한 문제점들을 해결하기 위하여 안출이 된 것으로서 흡판과 이송실린더, 벨로우즈 및 엘엠가이드등에 의하여 공급슈트에서 이송되어온 PCB를 공기압을 이용하여 정렬플레이트상에 정확한 위치가 결정되도록 한 것이 특정이다.Therefore, in the present invention, it is designed to solve the above problems, and the specific position of the PCB transferred from the supply chute by the sucker, the transfer cylinder, the bellows, the LM guide, and the like is determined on the alignment plate by using the air pressure. .

') Is formed and aligned by moving the PCB 24 supplied from the supply chute 12 in the direction of the guides 21 and 21'. It was allowed.

상기 정렬플레이트(14)상에 형성되는 공기배출공(22, 22', 23, 23')은 정렬플레이트(14)의 Z 축(25)을 중심으로 X 축(25')과 Y 축(25)의 교차점방향으로 경사지게 형성하여 공급된 PCB(24)가 가이드(21, 21') 방향으로 자연스럽게 이동하여 정렬되도록 한 것이다.The air discharge holes 22, 22 ′, 23, 23 ′ formed on the alignment plate 14 may have an X axis 25 ′ and a Y axis 25 about the Z axis 25 of the alignment plate 14. It is formed so as to be inclined in the direction of the intersection point of the supplied PCB (24) is to move naturally aligned in the direction of the guide (21, 21 ').

상기 공기배출공(22, 22', 23, 23')의 저면에는 공기집유실(30)이 마련되어 컴프레셔(31)로부터 공급호스(32)를 통하여 공기를 공급받도록 하였다.An air collecting chamber 30 is provided at the bottom of the air discharge holes 22, 22 ′, 23, 23 ′ to receive air from the compressor 31 through the supply hose 32.

상기 정렬플레이트(14)의 X 축(25')과 Y 축(25)의 교차점 부의에는 콘트롤러(33)와 연계된 PCB감지센서(34, 34')를 마련하여 정렬플레이트(14)상에 안치된 PCB(24)의 정렬상태를 감지토록 하여 본 고안의 PCB자동정렬장치(50)를 구성하였다.At the intersection of the X-axis 25 'and the Y-axis 25 of the alignment plate 14, PCB sensing sensors 34 and 34' associated with the controller 33 are provided and placed on the alignment plate 14. The automatic PCB alignment device 50 of the present invention was configured to detect the alignment state of the PCB 24.

상기와 같이 구성된 본 고안의 작용관계를 살펴보면, 검사를 행할 PCB는 공급슈트(12)내에 간지를 개입시킨체 무작위로 적재되어있게 되는데 이러한 PCB는 흡판과 이송실린더 및 벨로우즈, 엘엠가이드등의 이송수단에 의하여 한매씩 정렬플레이트(14)상으로 공급이 되며, 이러한 일련의 동작들은 종래의 기술과 동일하므로 상세한 기술의 업금은 회피한다.Looking at the working relationship of the present invention configured as described above, the PCB to be inspected is randomly loaded through the interleaver in the supply chute 12, such PCB is a suction plate and a transfer cylinder and bellows, such as conveying means By one by one is supplied on the alignment plate 14, this series of operations are the same as the prior art, so the up payment of the detailed technology is avoided.

이때 공급되는 PCB는 정렬이 되지않은 상태로 정렬플레이트(14)상에 안치가 된다.At this time, the supplied PCB is placed on the alignment plate 14 in an unaligned state.

그러면, 상기 PCB가 안치됨과 동시에 컴프레셔(31)가 작동하여 공급호스(32)를 통하여 정렬플레이트(14)의 저면에 형성된 공기집유실(30)로 압축공기를 불어넣게된다.Then, the PCB is placed and at the same time the compressor 31 is operated to blow compressed air into the air collecting chamber 30 formed on the bottom surface of the alignment plate 14 through the supply hose 32.

상기 공기집유실(30)에 공급된 공기는 정렬플레이트(14)의 상면과 도통되게 형성된 공기배출공(22, 22', 23, 23')를 통하여 배출이 된다.The air supplied to the air collecting chamber 30 is discharged through the air discharge holes 22, 22 ′, 23, 23 ′ formed to be conductive with the upper surface of the alignment plate 14.

그러면, 정렬플레이트(14)상에 안치된 PCB는 공기배출공(22, 22', 23, 23')를 통하여 불어나오는 공기에 의하여 정렬플레이트(14)의 X 축(25')과 Y 축(25) 방향에 고정된 가이드(21, 21')방향으로 이동되고, 이동된 PCB는 가이드(21, 21')에 부딪히면서 정렬이 되는 것이다.Then, the PCB placed on the alignment plate 14 is moved by the air blowing through the air discharge holes 22, 22 ′, 23, 23 ′ and the X axis 25 ′ and the Y axis ( 25 is moved in the direction of the guide (21, 21 ') fixed in the direction, and the moved PCB is to be aligned while hitting the guide (21, 21').

상기 PCB가 공기배출공(22, 22', 23, 23')를 통하여 배출되는 공기에 의하여 정렬플레이트(I4)의 가이드(21, 21')방향으로 이동할 수 있는 것은 정렬플레이트(14)상에 형성되는 공기배출공(22, 22', 23, 23')이 Z 축(25)을 중심으로 X 축(25')과 Y 축(25)의 교차점 방향으로 경사지게 형성되어 있으므로 정렬플레이트(14)상에 안치된 PCB(24)는 자연스럽게 가이드(21, 21')방향으로 이동되어 정렬이 되는 것이다.It is possible for the PCB to move in the direction of the guides 21, 21 ′ of the alignment plate I4 by the air discharged through the air discharge holes 22, 22 ′, 23, 23 ′ on the alignment plate 14. Since the air discharge holes 22, 22 ′, 23, 23 ′ formed are inclined in the direction of the intersection of the X axis 25 ′ and the Y axis 25 with respect to the Z axis 25, the alignment plate 14 is formed.
