Abstract

본 발명은, 평면화된 다수의 필름을 적층하여 그 편향부에서 소정의 형상으로 포밍에 의해 성형시킴으로써 편향부재를 제조하는 음극선관의 필름형 편향부재 제조방법 및 그 편향부재를 제공한다. 그 제조방법은, 상기 평면화된 다수의 필름의 각 편향부 사이에 각각 열경화성 수지층을 형성시키면서 다수의 필름을 적층시키는 단계; 그 적층된 다수의 필름의 편향부를 평면 상태로 가접합시키는 단계; 그 가접합된 다수의 필름을 소정의 온도로 표면이 가열된 포밍금형에 로딩하여 그 편향부를 소정의 형상으로 포밍시키는 단계; 그리고 상기 포밍단계에서 편향부를 소정의 형상이 유지되도록 가압한 상태하에 상기 포밍금형을 냉각시켜 그 포밍된 편향부를 소정의 형상으로 고형화시키는 단계를 포함하는 것을 특징으로 한다. 이에 따라, 필름이나 도선의 파손이나 손상없이 또한, 주름없이 소정의 형상으로 필름형 편향부재를 제조할 수 있으며, 고온 포밍시 열에 의해 열경화성 수지층이 경화되어 편향부의 소정의 형상을 더욱 견고하게 유지할 수 있을 뿐만 아니라 음극선관의 작동 중에도 그 온도 상승에 따른 변형이 일어나지 아니하게 되어 그 소정의 편향 자계 패턴이 시간 경과에 따라서도 변함이 없이 일정하게 되는 등의 효과가 있다.The present invention provides a method for producing a film-type deflection member of a cathode ray tube for producing a deflection member by laminating a plurality of planarized films and molding them in a predetermined shape at the deflection portion thereof, and a deflection member thereof. The manufacturing method includes the steps of: stacking a plurality of films while forming a thermosetting resin layer between respective deflection portions of the plurality of planarized films; Preliminarily joining the deflection portions of the laminated plurality of films in a planar state; Loading the plurality of temporarily bonded films into a forming mold whose surface is heated to a predetermined temperature to form the deflection into a predetermined shape; And cooling the forming mold under a state in which the deflection portion is pressed to maintain a predetermined shape in the forming step, and solidifying the formed deflection portion into a predetermined shape. As a result, the film-type deflection member can be manufactured in a predetermined shape without damage or damage to the film or conductive wire, and without wrinkles, and the thermosetting resin layer is cured by heat during high temperature forming to maintain the predetermined shape of the deflection portion more firmly. In addition, the deformation of the cathode ray tube does not occur even during operation of the cathode ray tube, such that the predetermined deflection magnetic field pattern is constant without change over time.
