用于波峰焊机的链爪清洗机构
本专利技术涉及一种链条上的链爪清洗装置,具体应用于波峰焊机的链爪清洗。
技术介绍
随着电子产品的发展,PCB上的元件的焊接越来越多。波峰焊工艺是焊接不可缺少的工艺步骤。波峰焊机的PCB传输一般都采用链条上安装指爪(也叫链爪)的方式来完成传输。由于链爪在整个焊接过程中不停的出入锡炉,链爪会粘锡,从而影响链爪的再次使用,也会造成锡的浪费。现有技术中通常将人工进行链爪的清洗,或者固定安装一圆柱毛刷链爪经过该毛刷后顺便完成清洗过程,人工清洗浪费时间,而且在波峰焊机运转时不易操作;然而固定的圆柱毛刷其磨损较大。
技术实现思路
本专利技术要解决的技术问题是提供一种自动清洗波峰焊机链爪的清洗机构,该清洗机构在不进行清洗工作时不与链爪接触。本专利技术解决其技术问题所采用的技术方案是:用于波峰焊机的链爪清洗机构,链条轨道固定安装在支架上,链条轨道两端安装链轮,链轮上安装有链条,用于夹持PCB板的链爪均匀的安装在链条侧面,上述链条以及链爪的外侧安装圆柱毛刷,该圆柱毛刷套装在一转轴上,其转轴安装在转轴座内的轴承上,本清洗机构还包括用于驱动该圆柱毛刷与链爪接触和分离的驱动机构。进一步的是:上述清洗机构还包括一清洗支架,该清洗支架安装在链条轨道下方或者由支架侧面引出,呈L状,所述的驱动机构为一水平安装的气缸,气缸通过紧固螺栓固定安装在清洗支架上,气缸推杆与气缸的活塞连接,气缸推杆端部安装转轴座,转轴座内安装有轴承,轴承内安装转轴,转轴上套装所述的圆柱毛刷。进一步的是:上述的驱动气缸为竖直向上的安装的气缸,气缸安装在支架侧面,气缸推杆的顶端安装转轴座。优选的是 ...
