1、Manipulator is now used as a industrial robots in use, the control objectives often appear often in industrial automation. Industrial automation technology has gradually matured, as mature a technology line has been rapid development in industrial automation as a separate subject. Manipulator applic
2、ation began to filter into welding, logistics, mechanical processing, and other industries. Especially at high or very low temperatures, full of poisonous gases, high radiation case, robot in similar circumstances showed great use also brings great convenience to the staff. Precisely because of this
3、 robot to get peoples attention began to be a high degree of development. Labor rates, working conditions, labor intensive aspects of promoting development. Both at home and abroad to develop the PLC (programmable logic controller) is in various special circumstances and under special conditions set
4、 for mechanical devices. Now turned on the development of the microelectronics automatic control technology and the rapid development of the trains, the success of PLC hardware software and simulation control win big and successful development, now continues to develop as a factory automation standa
5、rds. Because robots are good development of the technology makes a good optimization of productive capital, and robot shows this unique advantages, such as: has good compatibility, wide availability, hardware is complete, and programming that can be mastered in a short time, so in the context of ind
6、ustrial PLC applications became ubiquitous. Manipulator in many developed country agriculture and industry has been applied, such as the use of mechanical harvesting large areas of farmland, repeated operations on the high-speed line that uses a robotic arm, and so on. Today, the high level of autom
7、ation combined with restrictions on the manipulator development level is slightly lower than the international. The design is mainly arm welding machine by PLC Automation control. This of design let designers on in school by learn of has a must of consolidation, understand has some usually didnt opp
8、ortunities awareness in world range within some leading level of knowledge has has must awareness, hope designers can in yihou of design in the can success of using in this design in the proceeds of experience 1.2 manipulator in both at home and abroad of research profile automation mechanical arm r
9、esearch began Yu 20th century medium-term, after years with with computer and automation technology of development, Makes mechanical arm on the Grand stage of industrial automation and shine, gradually became an industrial evaluation standards, and its importance can be seen. Now original robotic ar
10、m spent most of mass production and use on the production line, which is programmed robotic arm. As the first generation of manipulator position control systems main features, although not back several generations that can detect the external environment, but can still successfully complete like wel
11、ding, painting, delivery as well as for materials simple movements. Second generation mechanical arms are equipped with sensors and manipulators have the environment there is a certain amount of sense, when the mechanical arm is to use the program as a basis. Difference is that the robot begand通启高速公
12、路TQ-11标 南京市交通工程总公司通启高速公路工程TQ-11标二灰碎石底基层施工作业指导书通启高速公路TQ-11标项目经理部二三年四月in hot water. After cooling to room temperature, add 2-3 drops of phenolphthalein indicator solution, based on standard titration solution of potassium hydroxide (0.05mol/L) Titrate first reddish, and do not fade in the 0.5min is th
13、e ending point. If there is no standard solution of potassium hydroxide, use the timed drops of sodium hydroxide solution, multiplies the ratio still 56.11.aM-weighing oil-like quality, measured in grams (g) 56.11-standard volumetric solution of potassium hydroxide and 1.0mL c (KOH) =1.000 mol/L qui
14、te a number of milligrams of potassium hydroxide. Results to two significant figures. 6, precision under repeatability conditions to obtain the absolute value of the difference of two independent measurement of results will be more than the arithmetic mean of 10% peroxide value GB19300, peroxide val
15、ue, 1 titration GB/T5009.37 4 2 1, principles of oxidation of fats peroxide, potassium iodide, generates free iodine by titration with sodium thiosulfate solution du, calculate content. 2, agents saturated potassium iodide solution: weigh 14g Ki plus 10mL water solution and, if necessary, micro heat
16、 make it dissolve, cooled and stored in a Brown bottle. Chloroform a mixture of glacial acetic acid: volume 40 mL trichloromethane, Lewis acid with 60 mL ice and shake well. Titration with sodium thiosulfate standard c (Na2S2O3) =0.0020mol/L. Starch indicator (10 g/l): soluble starch weighing 0.50,
17、add a little water, tune into a paste, add 50mL in boiling water and mix thoroughly and boil. Pro available now match. 3, sample analysis steps process:manipulator control mode and programmable controllers introduction 2.1 Select discussion with manipulator control 2.1.1 classification of control re
18、lays and discrete electronic circuit can control old industrial equipment, but also more common. Mainly these two relatively cheap and you can meet the old-fashioned, simple (or simple) industrial equipment. So he can see them now, however these two control modes (relay and discrete electronic circu
19、its) are these fatal flaws: (1) cannot adapt to the complex logic control, (2) only for the current project, the lack of compatibility and (3) not reforming the system with equipment improvements. Spring for the development of Chinas modern industrial automation technology the substantial increase i
