일반적으로 반도체 패키지는 일련의 공정을 통하여 제조된 후에 출하 전에 정밀한 검사를 마치게 되는데, 이러한 정밀 검사는 반도체 소자의 패키지 내부 불량뿐만 아니라, 그 외관에 미소한 결함이 발생하더라도 성능에 치명적인 영향을 미치게 되므로, 전기적인 동작 검사뿐만 아니라, 비전 카메라를 이용한 외관 검사와 같은 여러 가지 검사를 수행하게 되며, 반도체 패키지의 이송을 위해 다양한 형태의 픽커가 구성된다. In general, after a semiconductor package is manufactured through a series of processes, a detailed inspection is completed before shipment. Since such a detailed inspection has a fatal effect on performance even if a small defect occurs in the exterior as well as an internal defect in the package of the semiconductor device. , electrical operation inspection as well as various inspections such as appearance inspection using a vision camera are performed, and various types of pickers are configured to transport semiconductor packages.
한편, 패키지의 사양변경 등과 관련하여 트레이의 피치, 턴테이블의 피치 등이 변하는 경우가 있으며, 이에 대응하여 픽커도 그 피치가 자동으로 조절될 수 있도록 캠 플레이트방식과 링크방식, 원통 캠방식 등의 픽커 간격 조절장치가 구성되며, 픽커에는 무빙블록에 의해 지지되는 형태로 이동되면서 피치 조절이 이루어지도록 구성된다. On the other hand, there are cases where the pitch of the tray and the pitch of the turntable change in connection with the specification change of the package, and in response to this, the pickers such as the cam plate method, the link method, and the cylindrical cam method can automatically adjust the pitch of the picker. A gap adjusting device is configured, and the picker is configured to adjust the pitch while moving in a form supported by the moving block.
그러나, 쏘팅픽커의 이동을 담당하는 무빙블록과 LM 가이드의 경우, 내부에 장착된 볼과의 사이에 존재하는 갭으로 인해 무빙블록과 LM 가이드 간에는 미세한 유격이 존재하게 되고, 결국 이러한 유격으로 인해 픽커가 흔들리면서 픽커의 피치조절시 오차가 발생하는 문제점이 있다.However, in the case of the moving block and the LM guide, which are responsible for the movement of the sorting picker, due to the gap between the moving block and the LM guide, there is a fine play between the moving block and the LM guide. There is a problem in that an error occurs when the pitch of the picker is adjusted due to the shaker shaking.
