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.

1.4.5 刮锡系统 Solder paste removed system

组成：包括印刷头（刮刀升降行程自动调节装置、刮刀片安装部分）、刮刀横梁及刮刀驱动部

分（步进马达、驱动皮带等）等。

Component: Printing head (scraper lifting movement automatic adjustment device, scraper

blade assembling section), scraper beam, scraper drive section (stepping motor,

driving belt) etc..

功能：悬浮式能平衡自重的自适应刮刀，刮刀 Y 方向驱动使用随动结构，双滑块线性导轨，

印刷平稳,动作敏捷，独立直联式步进马达控制,内置精确压力控制系统，能精确的测定刮刀原

始压力值,无需顾及刮刀片类型，长度，重量或者厚度的变化.可编程实现印刷工艺灵活多变。

Function: Suspended, balanced and adaptive scraper. The driving on the Y direction of the

scraper is moving structure. The linear rail has two sliders. These make the printing even,

stable and fast. Controlled by the independent and direct stepping motor. Accurate

pressure control system can set the original pressure value precisely regardless of the

change of the type, length, weight and thickness of scraper. It can be programmed to insure

the flexibility of the printing technology.

1.4.6 电控系统 Electronic control system

组成:Windows XP 操作系统，集成电路，智能化的先进软件控制。

Component: Windows XP system, integrated circuit, advanced intelligent control

software

特点：安全，维修方便，极大地方便了用户的使用。

Feature: Safe, convenient maintenance and easy operation.

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

component let the low viscosity solder paste go through the window and it will be printed

on the PCB bonding pad. The clear solder paste picture will remains after the table

descends.
