Description

PCB의 선별분리장치PCB Separation Device

본 고안은 PCB 선별분리장치에 관한 것으로, 특히 컨베이어벨트상에서 이송중인 PCB를 선별하여 분리하는 작업을 자동으로 수행할 수 있는 PCB 선별분리장치에 관한 것이다.The present invention relates to a PCB sorting device, and more particularly, to a PCB sorting device that can automatically perform the task of sorting and separating the PCB being transported on the conveyor belt.

PCB (Printed Circuit Board)는 종이 에폭시 또는 유리 에폭시계의 판 위에 동박을 입혀서 필요한 회로를 인쇄하고 그 이외의 부분은 제거한 것으로, 이 위에 IC 기타의 부품을 납땜으로 부착하여 사용한다. PCB에 장착된 부품 및 납땜상태등은 일정한 검사과정을 거치며, 이러한 검사를 수행하는 시스템에서는, 검사를 마친 PCB중에서 양품 PCB는 다음공정으로 이송하고, 불량으로 판정된 PCB는 양품과 분리하여 다음공정으로 이송되지 못하도록 하는 수단이 필요하다.Printed Circuit Board (PCB) is printed on a sheet of paper epoxy or glass epoxy based copper foil to print the necessary circuit, and other parts are removed, and the IC and other parts are attached by soldering. The parts and soldering state mounted on the PCB go through a certain inspection process, and in the system that performs such inspection, the good PCB is transferred to the next process among the finished PCB, and the PCB determined as defective is separated from the good There is a need for means to prevent transfer.

종래에는, 이러한 PCB의 선별분리 작업이 작업자에 의해 이루어 졌다. 즉, PCB 검사장치에는 작업자가 배치되고, 작업자는 PCB 검사장치에 표시되는 신호에 따라 PCB가 양품인지 불량품인지를 파악하여, 불량으로 판정된 PCB는 양품 PCB와 분리하여 따로 적재하는 작업을 수행하였다. 그러나, 이러한 종래의 방식은, PCB의 선별분리 과정을 작업자의 수작업에 의존하게 되므로 인력과 시간의 소모가 심하며, 또 PCB 검사와 선별분리를 자동으로 행하는 무인화 시스템을 설계하는데 장애요인이 되어 왔다.Conventionally, such separation of the PCB has been performed by the operator. That is, a worker is placed in the PCB inspection device, and the worker grasps whether the PCB is good or defective according to the signal displayed on the PCB inspection device, and separates the PCB from the good PCB and loads it separately. . However, such a conventional method requires a lot of manpower and time since the PCB separation process is dependent on the manual labor of the operator, and has been an obstacle in designing an unmanned system that automatically performs PCB inspection and separation.

따라서 본 고안의 목적은, PCB 검사장치를 통과하여 이송중인 PCB중에서 불량 PCB를 작업자의 수작업에 의하지 않고 자동으로 선별분리할 수 있는 PCB 선별분리장치를 제공하는 것이다.Therefore, an object of the present invention is to provide a PCB sorting device that can automatically sort the defective PCB out of the PCB being passed through the PCB inspection device without the manual labor of the operator.

The signals of the position sensor A 36 and the position sensor B 37 are transmitted to the control unit, and the control unit is used to drive control the stopper 38 and the roller chains 10, 11, 12, 13, 14, 15.

도 3은, 이동지지체(2)와 고정지지체(3)에 설치되는 로울러체인(10,11,12, 13,14,15)의 부분상면도이고, 도 4는 부분측면도이다. 로울러체인(10,11,12,13,14 ,15)은 강판으로 만들어진 누에 모양의 링크(link)를 핀(pin)으로 연속하여 연결하고 그 사이에 부시(bush)와 롤러(roller)를 끼운 것을 말한다. 로울러체인(10, 11,12,13,14,15)은 크게 핀 링크(60)와 로울러 링크(50)로 구성되어 있고, 로울러 링크(50)는 로울러 링크 플레이트(51,52)와 부시와 로울러(53)로 구성된다. 로울러 링크플레이트(51,52)중 하나에는 롤러체인의 길이방향에 가로로 돌출하여 지지돌기(54)를 형성한다.3 is a partial top view of the roller chains 10, 11, 12, 13, 14, and 15 provided on the movable support 2 and the fixed support 3, and FIG. 4 is a partial side view. Roller chains (10, 11, 12, 13, 14, 15) are connected to a silkworm-shaped link made of steel plate in a continuous pin (pin) with a bush and a roller (between) Say that. The roller chains 10, 11, 12, 13, 14, and 15 are largely composed of a pin link 60 and a roller link 50, and the roller link 50 includes a roller link plate 51, 52 and a bush. The roller 53 is comprised. One of the roller link plates 51 and 52 protrudes horizontally in the longitudinal direction of the roller chain to form a support protrusion 54.

이상과 같은 구성에 의하여, 본 PCB 분리선별장치가 작동을 개시하면, 검사장치를 통과한 PCB(40)가 본체(1)로 이송되어 온다. 이때, 검사장치는 본체(1)에 있는 제어부로 이송중인 PCB(40)의 불량여부를 알리게 된다. PCB(40)가 불량인 경우에는, PCB(40)가 이송되어 위치센서 A(36)의 위를 통과하게 순간 위치센서 A(36)가 이를 감지하여 제어부로 신호를 보내게 된다. 이 신호를 받은 제어부는 스톱퍼(38)를 상승 구동시키고, 이에 의해 이송중인 PCB(40)는 목표적재위치에 정지하게 된다. PCB(40)가 정지하게 되면, 이를 위치센서 B(37)가 감지하여 제어부에 알리게 된다. 위치센서 B(37)로부터 신호를 받은 제어부는 구동모타의 구동을 멈추어서 컨베이어벨트(30)를 정지시킨 후, 각 로울러체인(10,11,12,13,14,15)을 일정 높이로 상승 구동시킨다. 이때, 로울러체인(10,11,12,13,14,15)의 지지돌기(54)는 PCB(40)의 양측연부를 지지하여 PCB(40)와 함께 상승한다. 이에 따라, PCB(40)는 컨베이어 벨트(30)로부터 분리되어 로울러체인(10,11,12,13,14,15)내에 적재된다.By the above configuration, when the PCB separation selecting device starts to operate, the PCB 40 passing through the inspection device is transferred to the main body 1. At this time, the inspection apparatus informs the control unit of the main body 1 whether or not the PCB 40 is being transferred. If the PCB 40 is defective, the instantaneous position sensor A 36 detects this and sends a signal to the controller so that the PCB 40 is transferred and passes over the position sensor A 36. The controller, which receives this signal, drives the stopper 38 up, whereby the PCB 40 being transferred stops at the target loading position. When the PCB 40 is stopped, the position sensor B 37 detects this and informs the controller. The control unit receiving the signal from the position sensor B (37) stops driving the drive motor to stop the conveyor belt (30), and then raises each roller chain (10, 11, 12, 13, 14, 15) to a certain height. Drive it. At this time, the support protrusions 54 of the roller chains 10, 11, 12, 13, 14, and 15 are supported together with both side edges of the PCB 40 to rise together with the PCB 40. Accordingly, the PCB 40 is separated from the conveyor belt 30 and loaded into the roller chains 10, 11, 12, 13, 14, and 15.

PCB(40)에 대한 적재가 완료되면, 제어부에 의해 스토퍼(38)의 하강하도록 제어되고, 구동모터가 작동을 개시하여 컨베이어밸트(30)를 움직이기 시작하여, 새로운 PCB(40)가 본체(1)로 이송되어 온다.When the loading on the PCB 40 is completed, the control unit is controlled to lower the stopper 38, and the driving motor starts to move the conveyor belt 30, so that the new PCB 40 is replaced with the main body ( It is transferred to 1).

PCB(40)가 양품인 경우에는, 검사장치로부터 이송중인 PCB(40)가 양품이라는 신호가 제어부에 전달되고, 이 경우에는, 제어부가 스톱퍼(38)와 로울러체인(10,11 ,12,13,14,15)를 구동시키지 않는다. 이에 따라 PCB(40)는 본체(1)를 통과하여 다음 공정으로 이송된다. 이러한 과정은 반복적으로 수행되어, 로울러체인(10,11,12 ,13,14,15)에는 불량 PCB(40)만이 칸칸마다 적재된다.When the PCB 40 is a good product, a signal indicating that the PCB 40 being transferred from the inspection device is a good product is transmitted to the control unit. In this case, the control unit includes a stopper 38 and a roller chain 10, 11, 12, 13. Do not drive. Accordingly, the PCB 40 passes through the main body 1 and is transferred to the next process. This process is performed repeatedly, and only the defective PCB 40 is loaded in each compartment in the roller chains 10, 11, 12, 13, 14, and 15.

상기의 예에서는 PCB가 양품인 경우에는 통과시키고, 불량인 경우에는 적재하는 예를 설명하였으나, 이러한 예에 한정되지 않고, PCB 선별분리장치를 검사장치이외의 다른 장치와 연계하여 사용하는 것도 가능하다. 이 경우 적재되는 PCB는 사용자에 선택에 따라 임의로 정해질 수 있다.In the above example, the PCB is passed in the case of good quality, and the example of loading in the case of failure is described. However, the present invention is not limited to this example, and it is also possible to use the PCB sorting device in connection with other devices than the inspection device. . In this case, the PCB to be loaded may be arbitrarily determined by the user.

이상 설명한 바와 같이, 본 고안에 따르면, 검사장치를 통과하여 이송중인 PCB중에서 불량으로 판정된 PCB를 자동으로 선별하여 분리할 수 있는 PCB 선별분리장치가 제공된다.As described above, according to the present invention, there is provided a PCB sorting device that can automatically sort and separate the PCB determined as defective in the PCB during the transfer through the inspection device.
