维修电工实训报告500字篇一
a) 了解电气控制系统中电气原理图、电器布置图及安装接线图的分析与画法;
b)掌握电动机运行中的直接启动、降压启动、调速控制方法及实现电路;
c)能熟练分析较复杂的控制电路、应用知识设计一般的控制电路;
d)学会基本的接线原则,认识并了解熔断器及交流接触器的功能,学会区分主回路和控制回路。
a) 熔断器fu,主要用作短路保护。在此实训过程中,我们使用rl系列螺旋式熔断器。工作原理:当电路发生短路故障时,熔断器电流超过某一规定值时,产生的热量使熔断体熔断,从而自动断开电路,起到保护作用。
b) 交流接触器km:主要由电磁系统、触电系统、灭弧装置、及辅助器件等组成。当接触器的线圈回路得电,线圈中流过电流产生磁场使铁心产生足够大吸引力、通过传动机构带动三对主触点和两对动合触点闭合,两对动断触点断开,当线圈失电时磁场消失,接触器复位。
c) 按钮开关sb:由按钮、复位弹簧、桥式动触点、动合静触点、动断静触点支柱连杆及外壳等部分组成。
d) 时间继电器kt,是一种利用电磁原理和机械的动作实现触点延时接通和断开的自动控制电器。实训中我们使用的是通电延时时间继电器。当线圈得电时,常闭触点直接接通。当设定的延时时间到后,常闭触点断开,常开触点闭合。
e) wdj24电机星型接法:略;wdj26电机三角型接法:略
a. 工具:螺钉旋具、尖嘴钳、斜口钳、剥线钳等等
b. 仪表:主要为万用表
c. 器材:控制板一块、行线槽、塑铜线、编码管、螺钉、平垫圈型号和数量按需而定
d. 元件:三相异步电机、组合开关、熔断器、交流接触器、按钮、端子排
1. 合上空气开关qf引入三项电源
2. 按下开关sb1时,交流接触器km线圈回路得电并自锁,km常开触点闭合,电机得电启动。由于接触器自锁,电动机一直工作,直到按下sb2后停止工作。 3. fr为电动机运行时的过载保护元件
1. 合上空气开关qf引入三项电源
2. 当按下正转按钮sb1后,km回路得电并自锁,电机开始正转工作。当需要改变电机转向时,直接按下反转按钮sb2,此时sb2串在km1回路的常闭触点断开,km1线圈回路失电,使电机停止转动,随后sb2的常开触点闭合,km2线圈回路得电,km2主触点闭合,电机引入与之前相反的的三项电源,因此电机开始反转。
3. fr为电动机运行时的过载保护元件。
1. 合上空气开关qf引入三相电源
2. 按下sb2开关,km1线圈回路得电,km1主触点闭合,km1自锁,电机
连续转动。此时,此时线路中串入的r起了降压启动的作用。经过设定时间后,时间继电器kt工作,km2线圈回路得电并自锁,将降压电阻r短接,因为未改变电源方向,电机提速不反向。sb1设置在主回路中是停止按钮。
控制电路如图下:略 实验原理如下:
1. 合上空气开关qf引入三相电源
2. 按下sb2,km1线圈得电,km1主触点闭合并自锁,为电机引入了三相
电源,km1主触点闭合后,km3主触点也闭合,电动机以星型连接直接启动。延时设定时间后,kt工作,km3主触点断开,km2主触点闭合并自锁,电动机以三角型连接直接启动。按下sb1,主控回路失电,电机m停止工作。
1. 合上空气开关qf引入三相电源
2. 首先按下按钮sb2,km1线圈回路得电并自锁,km1主触点闭合,电动机开始工作。按下sb1后,km1线圈回路失电,主触点断开,电机失电。因为惯性的存在,电机的速度不肯能直接减到零,因此速度继电器sr闭合,km2线圈得电,主触点闭合,电机慢慢减速。当n下降100r/min后,sr断开,电机停止工作。
1. 布线通道尽可能少,同路并行导线主控电路集中,单层密排,紧贴安装面布板。
2. 同一平面的导线不能交叉,非交叉步可的,该导线应在接线端子引出时,就水平架空跨越。
3. 布线应横平竖直,布线均匀。变换走向时应垂直。
4. 布线时严禁损伤线芯和导线绝缘。
5. 导线与接线端子或接线柱连接时,不得呀绝缘层,不反圈及不露铜过长。
本次实训的主要收获与体会:此次实训我学会了分析电气原理图及其画法,了解电机正反转、降压启动、星型到三角型启动、反接制动等的原理及方法、学会了各种控制电路的接线、分析及设计方法。学会了控制台和实验板的使用方法和注意事项。

通过实习给自己一个明确的定位,增强专业技能,锻炼综合运用所学的基础理论去独立分析和解决实际问题的能力,把理论和实际运用结合起来提高动手能力,为以后走上社会打下了一定基础。
(1)宁夏灵武长枣果胶酶产生菌的筛选;
(2)宁夏灵武长枣果胶含量的测定;
(3)为低年级学生做预试验;
(4)系特色试验项目:鲜啤的酿造;
(5)自酿鲜啤甲醇含量的测定。
在不知不觉中,为期几个月的实习结束了,这段时间带给了我太多的回忆与反思,我很庆幸能够在在实验室实习。这次实习让我收获颇多,在这几个月里,始终尽我最大的努力认真做好每一件事,虽然仍然是以一个学生的角色在实习,但是我以一个上班族的工作态度要求自己,将自己的很多优点放大化付诸于实验。进一步巩固了我的专业理论知识,培养了独立从事工作的能力,挑战自我及与人为善的品质,坚定了为梦想而奋斗的决心。在这两个月的时间里,我学到了很多东西,不仅有学习方面的,更学到了很多做人的道理,对我来说受益匪浅。在张老师和师兄师姐的帮助下,以及刘陆同学的团结合作下,我很快学习了各个实验方法、巩固了专业知识,这对于我今后进入社会是非常有益的。
“书到用时方恨少。”虽然做实验也是与专业相关的实验,但是在初入实验室的时候,就让我感觉到了自己的不足太多太多,平时学到的知识都仿佛记得却又很模糊,只是一个大的框架,还需要很多内容来充实,也充分说明了自己在平时的学习过程中没有很好的理解知识的体系及内容,这就导致每一次的新的实验,都是给我自己一次新的洗礼。重新翻书、在网络上查阅相关资料
“三人行必有我师焉。”在实验过程中,我有幸与刘陆同学结伴而行,两位同学各有春秋,刘的踏实,陆的丰富都让我有所收获。开始进入实验室的时候,对于实验室的的一切似乎有点似曾相识却无从下手的感觉,对于仪器设备可谓茫茫然不知所措,刘在这方面比较有天赋,认真的教我怎么使用,并且不厌其烦的倾心指导,让我很是感动;陆就像快乐催化剂,总是带给我愉悦的气氛,她有过很多社会实践,并且专业知识很牢固,在此期间,也给我很多帮助。在这里感谢两位同学与我共事实验室,感谢他们将各自给予我的帮助,他们都是我的小老师,我会将从他们那里学来的优势充分发挥。
“山重水复疑无路,柳暗花明又一村。”在宁夏灵武长枣果胶酶产生菌的筛选过程中,刚开始我们借鉴研究生学姐的经验,认为灵武长枣果胶酶产生菌就是黑曲霉,我们把方向定为黑曲霉的筛选,在一次次筛选过程中,总是以失败而告终,我们让长枣在室温下腐败,在培养箱给予一定温度腐败,但是长出来的菌始终都不是黑色的,我们接菌到培养皿里,想看看会有什么情况出现,长出来的是青霉菌,我们经过很多次重复,都是这样的结果,总是在这块儿就停止实验,重头再来,浪费了很长时间,后来我们索性看看继续实验下去会有什么样的情况,
继而发现了青霉菌球,让老师和我们都很惊讶并且欣喜。其实有的时候,有些事情不是没有结果,而是我们总是顾忌眼前的利害关系而没有勇气走下去。
“业精于勤。”在啤酒酿造过程中,前期准备工作是酿酒酵母的培养,由于我们的啤酒是下面酵母啤酒,之前用的是厂家发过来的,那批酒酿好了后,我们将发酵罐下面阀门打开取出酵母泥,进行培养。那就少不了要做培养基了,在培养基制备的过程中,要用到麦芽汁,初期少量,后期大量,一次次的麦芽汁糖化,由于起初方法不得当耗时长,实验效果不好。就比如说糖化开始时,我们直接用冷水和大麦芽混合,水浴锅升温,等待,糖化好了后过滤的时候采用最原始的方法,滤布过滤,效果也不好,麦芽汁的澄清度也不高。在熟练后,我们采用水温70℃和麦芽汁混合然后置于温度上升到65℃的水浴锅,而过滤的时候则采用粗滤后进行离心,这样将实验时间大大缩短,并且提高了培养基质量。
“师傅领进门,修心在个人。”在此期间,张谆谆教诲让我们受益匪浅,也有幸通过老师接触到了《中国传统文化》以及《水知道答案》,视频中的内容且不枚举,视频的主要目的就是让人们与人为善,做一个真善美的人,在看过之后,我不断地深思反省、警示自己要有样学样,还将其介绍给身边的亲朋好友,让大家也一起升华自己,在我向别人推荐的时候,大家都很感激,其实,在这里衷心的感谢张老师带我们入门。
在为期几个月的以实验为主的的实习中,我受益匪浅,我不仅学习到了专业知识,更重要的是收获了经验与体会,这些使我一生受用不尽,记下来以时刻自勉:
1.手脚勤快,热心帮助他人。初来匝道,不管是不是自己的份内之事,都应该用心去完成,也许自己累点,但你会收获很多,无论是知识与经验还是别人的称赞与认可。 毕竟师兄师姐们也都是从我们这个时候过来的,对于他们而言,哪些学生是认真的,哪些学生只是混时间,他们一眼就能看出。因为态度决定一些,一些小事,如刷培养皿、刷试管,大家都是从这里开始的,不能因为好高骛远就偷懒。只有用心地,以良好的态度做好这一件件小事,才能获得大家的认可,也只有这样,才有师兄师姐愿意更深入的教给我们一些技术和方法。
2.多学多问,学会他人技能。学问学问,无问不成学。知识和经验的收获可以说与勤学好问是成正比的,知识总是垂青那些善于提问的人。由于之前没有学过分子生物学,必然没有这方面的知识基础,很多东西不懂也是很正常的。所有的知识也都有一个从不懂到懂的过程,所以没有什么好丢脸的,不懂装懂才是真正的傻。此外,有一些经验上的东西,可能是关于细节的,在已知的基础上根据每个实验室的实验环境等因素进行了一些优化,这就需要我们及时的询问,才能少走弯路。
3.善于思考,真正消化知识。有知到识,永远不是那么简单的事,当你真正学会去思考时,他人的知识才能变成你自己的东西。就像刚才说的一样,由于理论知识不扎实,不系统,对于这些新的东西往往很难举一反三,融会贯通。这个时候,思考就是非常重要的。做之前思考,做完后还要回过头来思考。
4.前人铺路,后人修路。墨守陈规永远不会有新的建树,前人的道路固然重要,但是学会另辟蹊径更为重要。虽然现在对我们来说创新还不是件容易的事,但至少要有这种意识了。就是怀疑的态度和精神。其实就小的方面来说,很多方法和经验是一代代人口口相传而来的,那么其中误传也是难免的了。我们还是要抱着怀疑的精神,善于思考和发现,才是做科研应该具备的素质。从大的方面来说,本来对于研究身来说,就不是在单纯的学习知识,而是创造知识,可见对于
研究生而言,独立思考及创造的重要性。
5.实事求是做实验。不骗自己更不要骗他人。我想这一点的重要性,每一个学生都应该敲响警钟。实验结果是什么就是什么,不能剽窃抄袭、更不能伪造数据。只有正视实验结果,才能及时的找出存在的问题,有正对性的进行改进。
6.认真仔细地做好实验纪录。不要当你真正用到它时才知它的重要所在。可能对于一个本科生来说尚未这种意识,但我们可以想见其重要性。因为这些记录不仅仅是为了一个结果,为了能够毕业。更重要的是整个过程中自己不断总结的经验和教训、方法和规律都在里面。而其中的精华也只有记录者本身才能真正领悟吧!
在一次次理论与实践相结合的过程中,在老师们悉心指导下,我不但生物实验有了系统的理解,从无数次的失败中吸取了宝贵的经验教训,而且随着时间的推移,自己的意志也得到了磨练,恐惧心理也逐渐地消失了。我时刻提醒自己,唯有不断努力,才能与时俱进。总之,这次实习的意义,对我来说已不再是完成学分、完成毕业实习的任务,而是在开启“生命之旅”大门的过程中迈出了第一步。我一定会好好地珍惜这个机会,并为自己所喜爱的方向努力贡献自己的聪明才智。

第一周
通过这一个月的电工学习 ,我得到了很大的收获,这些都是平时在课堂理论学习中无法学到的,掌握了几种基本的电工工具的使用,导线与导线的连接方法,导线与接线柱的连接方法了解了电路安装中走线、元件布局等基本常识;了解了一般简单照明电路的安装方法,掌握了一般串联、并联电路,日光灯,电度表、插座的安装,了解了电动机传动和点动控制、顺序控制、逆反转控制的概念和原理,和具体的连方式,尤其是通过具体的实践,发现理论上已经很懂得东西,在实践当中并不是非常的熟练,知道了这是眼高手低,在以后的学习中一定多投入实践中去
第二周
通过第三个月的电工实习,我得到了很大的收获,第一、掌握了电烙铁的使用方法,以及元器件的焊接方法,例如电阻的两种焊接方法。第二、学会了导线绝缘层的拔出技巧,以及注意事项和单股铜导线的直接连接方法:小截面单股铜导线连接方法如图所示,先将两导线的芯线线头作x形交叉,再将它们相互缠绕2~3圈后扳直两线头,然后将每个线头在另一芯线上紧贴密绕5~6圈后剪去多余线头即可。单股铜导线的分支连接。单股铜导线的t字分支连接如图所示,将支路芯线的线头紧密缠绕在干路芯线上5~8圈后剪去多余线头即可。对于较小截面的芯线,可先将支路芯线的线头在干路芯线上打一个环绕结,再紧密缠绕5~8圈后剪去多余线头即可。第三、懂得了一些自动控制的原理,比如说半自动控制装置,全自动控制装置。最后我们还自己动手接了一个半自动控制装置。并且在这些授课过程中认识了很多元器件。了解一些线路原理以及通过线路图安装、调试、维修的方法;对电工技术等方面的专业知识做初步的理解;培养和锻炼我们的实际动手能力,使我们的理论知识与实践充分地结合,做到不仅具有专业知识,而且还具有较强的实际操作能力,能分析问题和解决问题的高素质人才。
第三周
在实际操作学习中,我懂得了电力系统的基本知识和变电所工作的重要性。让我认识了变压器、高压断路器、隔离开关和熔断器等。学习到了变压器的运行,互感器的作用,高压断路器的用途和隔离开关的作用、分类和型号。在什么情况下高压负荷开关与高压熔断器配合使用由熔断器起短路保护作用;在什么情况下高压电容器组的投入或退出运行应根据无功潮流、负荷功率因数和电压等情况确定。尤其是一些模拟活动使人身临其境,培养了我的胆大、心细、谨慎的工作作风。知道操作的时候要心细、谨慎,避免触电及意外受伤等危险事故的发生。通过实操,我确实是学到了很多知识,拓展了自己的的视野强了我的动手操作的能力,和实际运用能力。
第四周
保证电器设备正常运行是我们运行电工使命。安全、有效、合理、正确使用电是我们电工的工作。巡视电气设备不得靠近避雷器和避雷针,穿戴劳保品的要求等等,电工安全基础知识是电工必备的。做为运行电工,巡视工作非常重要,巡视可以发现设备运行中出现在主控室无法监视得到的问题,是在现场发现设备运行是否正常重要途径,是保证设备正常运行关键性的工作。我们运行人员在这项工作中不可走马观花、草率应付、掉以轻心去完成。在5个月工作里,我主要熟悉供电运行系统图,全厂的电气设备名称和编号、状态、位置。在日常工作中,开、结工作票,倒闸操作,识别信号报警,监盘,事故处理,这些工作内容我都做到熟悉和掌握。经历了五个月,我觉得自己还存在一些不足,对突发事故处理经验不足,电气设备工作原理,二次保护,运行设备维护,这些知识没有更深的理解。车间每周五进行技能和安全培训,事故处理经验的总结,这些有利我工作技能提升和丰富经验。

维修电工实训报告500字篇八
通过实习,为学生今后的专业实验、毕业设计准备必要的工艺知识和操作技能,同时培养学生严谨的工作作风和良好的工作习惯。既是基本技能和工艺知识的入门向导,又是创新实践的开始和创新精神的启蒙。
实习项目一:安全用电
(一)必须认识到安全用电的重要性
安全用电知识是关于如何预防用电事故及保障人身、设备安全的知识。在电子装焊调试中,要使用各种工具、电子仪器等设备,同时还要接触危险的高电压,如果不掌握必要的安全知识,操作中缺乏足够的警惕,就可能发生人身、设备事故。所以必须在了解触电对人体的危害和造成触电原因的基础上,掌握一些安全用电知识,做到防患未然。
(二)触电及相关防护策施
1.触电的种类:
(1)电伤,电伤通常有灼伤、电烙伤、皮肤金属化三种。电伤对人体造成的危害一般是非致命的。
(2)电击,是指电流流过人体,严重影响人体呼吸、心脏和神经系统,造成肌肉痉挛、神经紊乱,导致呼吸停止,严重危害生命的触电事故。触电死亡大部分是电击造成的。决定电击强度的是流经人体的电流,而非电压。
2.影响触电造成人体伤害程度的因素:电流的大小、电流种类、电流作用时间、电流途径、人体电阻。人体电阻会随着人体皮肤的干燥程度和人的年龄而变化。干燥时可呈现100 000欧姆以上,二潮湿时,电阻可降到1000欧姆以下,并且随着人的年龄的增加而变大。
3.触电原因:直接触电、间接触电、静电触电、跨步电压引起的触电。
4.防止触电的技术措施:
(1)保护接地和保护接零
(2)触电保护装置
还有一点比较重要就是若真的看到别人发生触电,该采取些什么样的措施。先保证把电源断开或用绝缘体把电线从触电者身上移开,若触电者呼吸停止但有心跳,应对其进行人工呼吸或胸外心脏挤压。
实习项目二:常用工具的使用
(一)照明电路的组装常用工具:熟悉和掌握常用电工电子工具的结构、性能、使用方法和操作规范。有螺丝刀、钳子、电工刀等。照明电路的组装的实习内容:
(二)一灯一开关控制的白炽灯照明电路组装。线路上依次火线接开关,白炽灯、之后接零线,便构成回路。
(三)日光灯照明电路的组装:其主要由开关、启辉器、镇流器和日光灯等部分组成。
(四)双控照明电路的组装:两个开关中的.任何一个无论处于什么状态,另一个开关都能独立地控制电灯的开、关。
实习项目三:常用电子仪器的使用
1.实习项初步掌握ss4323直流稳压电源的使用方法
2.初步掌握ut58d数字万用表的使用方法
3.初步掌握as101e函数信号发生器的使用方法
4.初步掌握ss-7802a模拟示波器和tds1012数字存储示波器的使用方法。
实习项目四:常用电子元器件的认识与检测
(一)通过静态和动态的方法,初步认识电阻及掌握其检测方法
(二)通过静态和动态的方法,初步认识电位器及掌握其检测方法
(三)通过静态和动态的方法,初步认识电容及掌握其检测方法
(四)通过静态和动态的方法,初步认识电感及掌握其检测方法
(五)通过静态和动态的方法,初步认识二极管及掌握其检测方法
(六)通过静态和动态的方法,初步认识三极管及掌握其检测方法。
实习项目五:常用工具的使用
(二)焊锡训练常用工具:
继续来熟悉和掌握常用电工电子工具的结构、性能、使用方法和操作规范:电烙铁。
焊锡训练的实习内容:印制电路板的焊接练习。其内容:在万用板上焊接一个如书上的图的无稳态多谢振荡电路并通电测试,若两个发光二极管能轮流发光,则表明电路焊接正确。
实习项目六:印刷电路板(pcb)的制作与电路调试制作一个555振荡电路。
第一周的时候我进行了电子电工的实习,师傅给我们讲了安全用电的有关知识,这个跟我们的日常生活都有关,而且让我们对如何安全用电等的知识在原有的基础有了进一步的了解,通过师傅的讲解,我学习到了安全用电的基本知识,懂得安全用电的重要意义,并且这为电工电子实习和以后的学习、工作、生活中安全用电奠定基础。为期一周的电子电工实习,师傅也大致的向我们叙述了一下今后的实习计划并且说明了一些要求和注意事项,这也让我对往后的实习充满期待和好奇。
第二周我们进行了照明电路的组装,在听师傅介绍我们这节课的内容后,我们开始动手。我们是两个人一组,自己动手把线路连接好,然后接通电路,让电灯亮。看到自己组装的灯亮了,很开心,师傅过来签名时也许也觉得我们像个小孩,分享着我们的喜悦,微笑着帮我们签了名。这次我们组进行的很顺利,虽然过程中也有遇到一些些小难题,但在师傅的耐心并且细心的讲解下我们及时改正也是不成阻碍,师傅总是能一针见血的指出我们的问题所在,并且给与我们正确的引导,并且同时教会了我们如何去找出出错的地方。在这次实操过程中让我初步亲身体验到电子电工是怎样的。通过这次的组装让我们了解到了什么是白炽灯、日光灯以及白炽灯、日光灯照明电路的基本组成。
第三周我们进行常用电子仪器的使用这个项目。我们在师傅的讲解下了解了直流稳压电源、万用表、信号发生器、示波器等常用电子仪器的功能后开始操作。我在使用示波器提进行校准信号方波的测量得到以下数据:峰值为0.44v,周期为10.4ma,频率为0.096hz;测得1.5khz、10db的正弦波的峰峰值为5.5v,则峰值为2.75v,周期为17ma,则由周期计算出频率,与显示的频率比较相差较小。通过这节课我掌握了直流稳压电源、万用表、信号发生器、示波器的基本使用方法,这也为我后续的实习打下了基础。f为2.75hz
实习的第四周我们进行的是常用电子元器件的认识与检测。在一开始通过师傅的讲解我们简单的了解了电阻、电位器、电容、电感二极管、三极管、集成电路路芯片等元器件的功能以及与它们相关的一些其它知识。在实习的过程中我通过实物认识各种常用的电子元器件并且掌握了常用电子元器件参数的识读方法以及使用万用表测量常用电子元器件参数的方法。在色环阻值识读中我识读了一个其色环为橙黑红银的四环电阻的阻值为30x100±5%并且用万用表测得其阻值为2.9千欧姆,则可以比较得出相差不多,也就证明前面的读数是正确的;然后用万用表测得电位器的最大阻值为0.01毫欧姆;用万用表和多用转接插头座测得电容得电容量为0.01毫欧姆,并且 我在这节课学会了二极管与三极管管脚的判别。做完上述步骤后,我们又制备了一个二极管的实验线路,我连接好线路,接通电源,二极管就亮了,所以电路的连接是成功的。通过这个简单的实验,让我了解了常用电子元器件的功能并且加深了对线路连接的认识。第二大节课我们在第一大节课的基础上开始我们的焊接工艺与焊接训练。同样在师傅的详细认真的讲解下。我们熟悉了电子装焊工艺的基础知识和要求后开始动手操作。我们要进行的是印制电路板的焊接练习。我们在万用电路板上按照电路图进行元器件的焊接,我刚开始焊接第一个元器件是二极管,手拿着那个电烙铁和锡一直不受控制的抖动,我一直对自己说要稳,可还是手很抖,也许是第一次接触紧张在所难免。我的第一次焊接尝试就在我手不停的抖动下结束了。但是也许是真正了解到焊接是怎么一回事了,知道了心里有底了,第二次焊我就焊得好多有了,手也不多抖了,并且越焊越熟手。有经验后,之后的我都焊接的很好。上午时间到时,同事们都还没有焊完,我也一样,师傅说先回去,下午来再继续。
第五周我们继续焊接工艺与焊接训练,同时老师也讲了as-06fm收音机的制作,做完上一个项目的同事就可以接着去做这个项目。下午我们都提早到了,一到就坐下来继续进行上午的焊接,没有了上午的害怕和紧张,这次我一拿起电烙铁就上手了,别说还真的是还有模有样的,这时的我们经过这些天的实习都有电工的架势了,我们来到时看到还有比我们早到的同事在焊接时都觉得仿佛进了电工厂了,这跟刚开始的感觉是不一样的。课上了不太久,我还在努力认真的焊接着,就有同事成功了。虽然我比其它同事慢了点,但我还是很稳的,我想不能在最后的时候没弄好才来出差错啊,所以我不紧不慢的一点点的认真的焊着。经过差不多一下午的努力我终于焊接好了无稳态多谐振荡电路的焊接,这时候最关键的时刻到来了,因为然后就是要用先前学习使用过的直流稳压电源进行通电测试,我带着紧张和期待的心情接通连接电路,按下output键,这时我看到两个发光二极管在轮流放光,一闪一闪的,我觉得真是很好看啊,我这时的心情真的可以用心花怒放来形容。那种认真努力得到收获的感觉那种成就感真的都很好。这个实习内容较之前面的内容花费的时间较多收获也较多。我觉得经过这次焊接以后叫我焊什么我都不怕了。并且呢我对电子装焊工艺及常用焊接、装配工具有了一个初步的认识,掌握了焊接工具及常用工具的正确使用以及手工电子焊接技术,为以后的制备收音机的实习产品安装打下了基础。
电子电工实习第六周也是实习的最后一周。今天我们实习的内容是印刷电路板(pcb)的制作与电路调试,在师傅的讲解下我们了解了制作pcb板电路图的基本流程,按照师傅所说的流程,我们顺利而且成功的完成了任务,让那我熟悉了制作pcb板的基本操作,掌握了使用热转印来制作pcb板的操作。
最后在我怀着留恋的情绪下这次的就这样结束了。在师傅的精心指导和同事们的积极帮助和我的认真努力下,实习圆满结束。接得进入工作岗位!
