The embodiment of the invention discloses a multi-functional cleaning air exhausting device and a manufacturing method thereof. The air exhausting device includes an air exhausting strip, a cleaning cylinder and a handle, wherein the cross section of the air exhausting strip is rectangular, the shape of the runway or octagonal, the cleaning cylinder is composed of an upper roller and a lower roller, and the outer circumference of the air exhausting strip and the cleaning cylinder is covered with a dust-free cleaning cloth layer; the top concave of the handle is provided with a shape and a bottom The roller is matched with the upper clamping groove with openings at both ends, and the bottom concave is provided with the lower clamping groove with openings at both ends. The depth of the lower clamping groove is less than the width of the air vent strip, and the cross section of the lower clamping groove is in the shape of an isosceles ladder with width inside and width outside. The cleaning cylinder is clamped into the upper clamping groove, and the air vent strip is clamped into the lower clamping groove. The invention improves the gas exhausting effect, is not easy to produce the bad exposure caused by the inadequate gas exhausting, avoids the rubber breaking caused by the friction between the gas exhausting strip and Mylar, reduces the quality risk, and increases the cleaning function; in addition, the invention can be replaced and reused, does not need to be fixed by screws, and is convenient for installation and disassembly.

多功能清洁赶气装置及其制造方法
本专利技术涉及PCB生产
,尤其涉及一种多功能清洁赶气装置及其制造方法。
技术介绍
在制作PCB过程图形转移工艺里的曝光是必不可少的。目前行业里曝光的类型也是多样化,常用的有手动对位曝光、自动对位曝光(CCD)和镭射曝光(LDI)。那么在传统的手动对位曝光时,赶气与清洁动作是不可或缺的,不同的公司对于赶气、清洁板面的辅助工具都各有不同。常见的赶气工具是用阻焊丝印的旧的刮刀与刮胶回收利用。而对于曝光前板面清洁动作,常常被忽略。目前,常用的手动赶气工具是使用阻焊刮刀作为赶气条,其使用弊端在于刮胶边口为直角,赶气过程中与Mylar接触面受限。若手动切割边口,将导致边口不平整,影响赶气效果;并且这种使用旧刮胶做为赶气工具,自身材质为胶体在不经任何加工的情况下直接用于赶气,赶气过程中与Mylay摩擦易产生胶碎,存在曝光品质风险。
技术实现思路
本专利技术实施例所要解决的技术问题在于,提供一种多功能清洁赶气装置及其制造方法,以使提升曝光品质。为了解决上述技术问题,本专利技术实施例提出了一种多功能清洁赶气装置,包括赶气条、清洁筒、手柄,其中,赶气条的横截面为长方形、跑道形状或八边形,清洁筒由上辊和下辊组成,赶气条和清洁筒的外周均包覆有一层无尘清洁布层;手柄顶部凹设有形状与下辊对应匹配且两端开口的上卡槽,底部凹设有两端开口的下卡槽,下卡槽的深度小于赶气条的宽度,下卡槽的横截面为里宽外窄的等腰梯形状;清洁筒卡入上卡槽中,赶气条卡入下卡槽中。进一步地,手柄 ...
