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.

第二章 设备安装与调试
Chapter 2 Equipment installation and debugging
2.1 开箱 Open the equipment
开箱后，请您首先做好以下工作：
Do the following checks after opening the equipment
1. 对照《装箱清单》所列各项进行查验。
Recheck all in items on the packing list.
2. 检查机器各部分是否有损坏，包括另箱包装的显示器、键盘、鼠标及刮刀板等，并将
它们重新安装到印刷机上。
Check all the units, including the screen, keyboard, mouse and scraper board etc.
And assemble them on the printer.
3. 将运输导轨上的固定扎带剪开。
Cut off the fixed tie on the transmission rail.
4. 刮刀横梁固定在网框横杆上的，请将固定带剪开。
Scraper beam is fixed on the frame beam with the tie. Cut off the tie.
5. 请将网框横杆上的固定套松开，使网框支板能左右移动。
Loose the fixed sleeve on the frame beam so that the frame supporting board can
move left and right.
6. 将运输时安装的工作台固定板取下（如图 2 –1 示）。
Take off the fixed plate which is assembled inside the table during the
transportation.(see pix 2-1)
7. 检查各联接处是否有松动脱落，各运动部分传输皮带有无脱落。
Check all the connections are loosen or not and the transmission belts are loosen or
not.
8. 检查各直线导轨上的滑块有无滑脱。
Check the sliders on the linear rail slip or not
9. 检查电气元件是否固定、接触是否良好。
Check electronic components are fixed or not, connected or disconnected.
