Abstract

본 발명은 전자부품이 실장된 PCB를 일정온도 가열하고, 이를 자동적으로 반전시킬 수 있도록 한 가열 및 자동 반전장치에 관한 것으로 그 기술적인 구성은, PCB(2)가 이송되는 기판이송 컨베이어(3)의 일단에 로드레스 실린더(4)가 설치되며, 상기 로드레스 실린더(4) 선단에는 스프링(5)에 탄설된 스토퍼(6)가 입설되어 연결체인(7)과 연설된 안내격판(8)내에 상기 PCB(2)를 진입시켜 삽입토록설치되며, 양측 스프라켓 휘일(9)(9')과 연서된 연결체인(7)상에 기판 삽입홈(11)이 형성된 안내격판(8)이 입설되며, 상기 안내격판(8)의 기판 삽입홈(11)내에 PCB(2)가 삽입되어 수직방향으로 입설되며, 상기 PCB(2)가 고정된 안내격판(8)이 연결체인(7)상에 수직으로 입설되어 건조로(12)를 통과토록 설치되고, 단열재(14)가 주연에 착설된 건조로(12)의 상측으로 히이터(15)가 횡설되며, 상기 히이터(15) 양측은 모터(16)와 연설된 송풍팬(17)이 설치되어 연결체인(7)을 통해 이송되는 PCB(2)를 일정온도 가열토록 하며, 상기 건조로(12)의 후방에 기판 이송 컨베이어(18)가 설치되고 연결체인(7)상에 안내격판(8)을 개재하여 입설된 PCB(2)가 체인 반전부(19)에 진입시 PCB(2)가 기판삽입홈(11)내에서 자중으로 이탈되어 자동으로 반전토록 되는 것이다. 이에 따라서, 전자부품이 실장된 PCB를 자동적으로 이송하며 이를 일정온도 가열하여 PCB가 전자부품 전기적 실장상태를 손쉽고, 용이하게 검사토록 하며, PCB의 세트 조립전에 불량기판을 조기 발견하여 제품의 신뢰성을 향상시키면서 작업성 및 생산성을 향상시킴은 물론, 전자부품이 실장된 PCB를 자동으로 반전시켜 차기 공전인 부품이면의 리이드 커팅 공정의 효율을 향상시킬 수 있는 것이다.The present invention relates to a heating and automatic reversing apparatus for heating a PCB on which an electronic component is mounted at a constant temperature and automatically inverting the PCB. The technical configuration of the present invention is a substrate transfer conveyor (3) to which a PCB (2) is transferred. A rodless cylinder 4 is installed at one end of the rodless cylinder 4, and a stopper 6 mounted on a spring 5 is installed at the tip of the rodless cylinder 4 in the guide plate 8 protruding from the connecting chain 7 to the end thereof. A guide plate 8 having a substrate insertion groove 11 formed therein is installed on the connection chain 7 connected to both sprocket wheels 9 and 9 'to enter and insert the PCB 2. The PCB 2 is inserted into the substrate insertion groove 11 of the guide plate 8 to be inserted in the vertical direction, and the guide plate 8 to which the PCB 2 is fixed is vertically mounted on the connection chain 7. The heater 15 is horizontally placed on the upper side of the drying furnace 12 in which the heat insulator 14 is installed on the periphery. On both sides of the heater 15, a blower fan 17, which is extended from the motor 16, is installed to allow heating of the PCB 2 transferred through the connection chain 7 to a predetermined temperature. The substrate transfer conveyor 18 is installed at the rear and the PCB 2 enters the chain inverting portion 19 when the PCB 2 entered through the guide plate 8 on the connection chain 7 enters the chain inverting portion 19. 11) it will be displaced to its own weight and automatically reversed. Therefore, it automatically transfers PCB mounted with electronic parts and heats it to a certain temperature so that PCB can easily and easily inspect the electrical mounting state of electronic parts. In addition to improving workability and productivity, the PCB mounted with electronic components can be automatically reversed to improve the efficiency of the lead cutting process for the next idle component.
