1.4.4.2 钢网清洗系统-擦拭组件 Stencil cleaning system-wipe component
组成：包括真空管、文丘里管、鼓风机、清洗液储存和喷洒装置、卷纸装置、升降气缸等。
网板清洗装置被安装在视觉系统后面，通过视觉系统拖动清洗系统移动，自动清洗网
板底面。
进行清洗时清洗卷纸上升并且贴着模板底面移动，用过的清洗纸被不断地绕到另一滚
筒上。清洗间隔时间可自由选择，清洗行程可根据印刷行程自行设定。进行湿洗时，
当储存罐中清洗液不够时，系统出现报警显示，此时应将其充满清洗液。干、湿、真
空洗周期可自由调节。
Component: It includes vacuum tube, venturi tube, blower, liquid restore and spraying
device, paper roller, lifting cylinder etc.. Stencil cleaning device is assembled behind the
visual system. Cleaning system will remove by the dragging from visual system. The
bottom of the stencil will be cleaned automatically.
The cleaning roller paper lift up and remove on the bottom of the template when do the
cleaning. The used cleaning paper will roll to another roller continually. The cleaning
interval can be selected freely. The cleaning movement can be set on the base of the
printing movement. Doing the wet cleaning, the system will alarm if there is not enough
cleaning liquid in the restore container. Then operator need full the container with cleaning
liquid. The cycle of the dry/wet/vacuum cleaning can be adjusted freely.
功能：
自动有效的分离式清洗结构，大功率风机加文丘里真空发生装置抽真空，喷射系统加可编程
的喷洒清洗液，干﹑湿﹑真空三种清洗方式,并可任意选择自由组合，用户可根据实际需求设
定清洗周期﹑时间及速度等参数，长短擦拭纸通用,拆卸方便,节约资源；加强型的真空栅,充
分利用风机效率, 彻底清除网板孔中的残留锡膏，保证印刷品质。
Function: Automatic, effective and separating cleaning structure. High power fan and
venture vacuum device do the vacuum pump. Spraying system, programmed spraying
cleaning liquid and three cleaning methods (dry/wet/vacuum). These can be selected and
combined freely. Operator can set the cleaning cycle, time, speed etc according to the
actual need. General paper is easy to assemble and disassemble and it can save resource.
Enhanced vacuum gate and good fan can removed the remaining solder paste in the hole
on the stencil. It can insure the printing quality.

1.5 工作原理 Working principles
由以上各部组成的全自动视觉印刷机在印刷焊膏时，锡膏受刮刀的推力产生滚动的前进，
所受到的推力可分解为水平方向的分力和垂直方向的分力。当运行至模板窗口附近，垂直方
向的分力使粘度已降低的焊膏顺利地通过窗口印刷到 PCB 焊盘上，当平台下降后便留下精确
的焊膏图形。
When the automatic visual printer prints the solder paste, the solder paste will move
forward with the force from the scraper. The force will be divided into horizontal component
and vertical component. When move to the nearby of the template window, the vertical
