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 7 操作系统，集成电路，智能化的先进软件控制。
Component: Windows 7 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.

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

2.1
吊装安全作业 Safe lifting operation
吊装作业是指用起重设备对物体进行悬挂或移动的工作。吊装作业属于高风险作业，要
求施工人员必须具有高度的技能、经验和责任心。在进行起重吊装作业前，请务必仔细阅
读本操作说明书，并严格遵守各项安全规定。作业时，请始终保持警觉，并确保操作人员
具备相应的操作技能和安全意识。任何情况下，安全始终是第一位的。
Lifting operation refers to the work of using lifting equipment to suspend or move objects.
Lifting operations are high-risk operations that require construction personnel to have high skills,
experience, and a sense of responsibility. Before carrying out lifting operations, please carefully
read this operating manual and strictly comply with all safety regulations. When doing homework,
please always remain vigilant and ensure that the operators have the corresponding operational
skills and safety awareness. In any case, safety always comes first.
2.1.1 术语和定义 Term and definition
1.吊装作业 Lifting operation
在检维修过程中利用各种吊装机具将设备、工件、器具、材料等吊起，使其发生位置变
化的作业过程。
The process of using various lifting equipment to lift equipment, workpieces, tools, materials, etc.
during maintenance and repair, causing them to change position.
2.吊装机具

系指桥式起重机、门式起重机、装卸机、缆索起重机、汽车起重机、轮胎起重机、履带
起重机、铁路起重机、塔式超重机、门座起重机、桅杆起重机、升降机、电葫芦及简易
超重设备和辅助用具。
Refers to bridge cranes, gantry cranes, loading and unloading machines, cable cranes, truck
cranes, tire cranes, crawler cranes, railway cranes, tower overweight cranes, gantry cranes, mast
cranes, elevators, electric hoists, and simple overweight equipment and auxiliary tools.
2.1.2 吊装作业的分级 Classification of lifting operations
吊装作业按吊装重物的质量分为三级：
Lifting operations are divided into three levels based on the quality of the heavy object being lifted
a)一级吊装作业吊装重物的质量大于 100t；
The weight of the heavy object lifted during the first level lifting operation is greater than 100 tons
b)二级吊装作业吊装重物的质量大于等于 40t 至小于等于 100t；
