Introduction to the safe use of SMT mounter
Safe use of the SMT placement machine includes personal and equipment safety Personal safety is the most important aspect It involves regulations and standards, corporate culture, corporate social responsibility, employee training, and rules and regulations This is necessary in the application of the placement machine We should constantly focus on the first priority
1. Three elements of safety foundation
1. Safety concept is fundamental
(1) Security is the basic demand of human beings
Security is one of the basic needs of human beings, the most basic survival needs of everyone, the foundation and lifeline of enterprise survival and development, and the fundamental guarantee of national economic development. Every member of the company, from senior executives to ordinary employees, should firmly establish the safety concept of "safety first, prevention first". Safety is the fundamental mode, regardless of the management mode or the profit model; No matter which production line, which production line, safety is the lifeline; Only safety can have safety; With security, only development can be achieved.
(2) Safety is the eternal theme of production
Safety is the eternal theme of production and will never change. Whether it is mining and transportation facing high risks or electronic manufacturing industry with relatively low risks, security risks are everywhere. High sense of responsibility, continuous safety awareness, and never relax safety thought are the fundamental guarantee of safe production; Carelessness and luck are always enemies of safety.
(3) Safety management focuses on prevention in advance
The characteristics of modern enterprise safety management are that safety management has gradually begun to transform from traditional accident handling to pre event prevention, from passive safety of "I want to be safe" to active safety of "I want to be safe, I will be safe". Today, we advocate people-oriented and scientific development to create a harmonious society. What is more important is to make the safety concept deeply rooted in people's hearts and implement it in all aspects.
2. Laws and regulations are the guarantee
(1) Regulations and standards are the basic guarantee
From international conventions, national laws and regulations, national standards, industrial standards, regional standards to enterprise standards, relevant safety regulations and standards provide basic security at all levels. For example, the National Labor Protection Law, the Labor Rights Protection Law and the Women and Children Rights Protection Law fundamentally stipulate the responsibilities and rights of relevant employers and employees in terms of labor safety and health; Various standards of equipment, tools and materials put safety first, all of which provide fundamental security.
(2) Hard won safety rules and regulations
In the SMT factory, there are almost no exceptions in all production processes, from the operation of the production line to the implementation of each process, and the safe operation of each equipment. There are various safety systems Most of these systems are formulated on the basis of scientific analysis, and there are also many regulations based on practical experience It can be said that many of the rules and regulations are painful lessons or even blood of the elders Illegal operation does not respect knowledge, predecessors, life and oneself
(3) The root cause of the accident has violation factors
Regardless of the nature of the accident, as long as careful analysis is made, it will be found that the safety regulations have not been implemented and are caused by violations. For example, misoperation accidents are caused by failure to comply with operating procedures, dispatching orders or industry regulations. Habitual violations are the root cause of the accident.
(4) Develop safety habits
The so-called habit is a kind of behavior pipeline, which is consolidated and becomes necessary due to repeated operation. Habits have a great influence on human behavior. Scientific research shows that only about 5% of a person's daily behaviors are non habitual, and the remaining 95% are habitual. In this regard, cultivating habits conducive to safety is an important way to reduce accidents and accident probability.
The premise of developing safety habits is to implement various rules and regulations, and the core is to form behaviors. The formation of habits requires a process and experience. Cultivating safety habits is the highest and ultimate goal of enterprise safety education, as well as the embodiment of employees' basic quality and the guarantee of happiness.
3. Scientific and technological measures are obstacles
Due to the importance of safety to human survival and development, and the seriousness of safety accidents in the development of modern science and technology, an independent safety science and technology has gradually formed in the field of modern science and technology, specializing in the occurrence and development of accidents, as well as the research and development of accidents. Prevention strategy and control technology. This book only covers a part of the field of safety technology, that is, the role of safety technical measures in industrial safety production.
(1) Safety awareness and rules and regulations cannot ensure safety
Humans are different from robots because they have seven emotions and six desires. No matter how high the safety awareness and perfect rules and regulations are, they cannot guarantee 100% safety. Errors or omissions can be said to be human characteristics or human nature. In addition, the robot may also be disturbed or malfunction. In this regard, it is necessary to provide the last barrier and defense line through security technology as far as possible.
(2) Safety technical measures shall prevent and tolerate human errors
Safety technical measures mainly use various science and technology mastered by human beings to provide the most complete safety guarantee for production process and equipment. This requires not only ensuring that people will not make mistakes, but also new security technology measures to prevent people from making mistakes. Buffer and tolerate human errors within a certain range. For example, the safety technology of detection, alarm and machinery alliance has been applied to many processing machines. When the detection mechanism senses that a part of the human body has entered a dangerous part, it will immediately give an audible and visual alarm and control the relevant parts of the machine to stop the movement that may cause an accident., In this case, even if the operator violates the regulations, the safety can still be guaranteed. With the development of modern sensor technology, automation technology, electronic information technology and tight control technology, various safety technical measures for processes and equipment are becoming more and more perfect, which will provide more and more reliable guarantee for human safety.
(3) Tasks of safety technology
1. Analyze the causes of various accidents;
2. Research methods for preventing various accidents;
3. Improve the intrinsic safety of equipment; 4. Strengthen the safety of equipment through scientific and technological measures.
Various safety technical measures are based on the principle of changing dangerous work into safe work, changing tedious work into simple work, and changing manual operation into automatic operation. The ultimate goal of safe production is achieved by improving safety equipment, working environment or operation methods.
(4) Science and technology security is still the first human factor
Any advanced PCBA technology needs to be mastered by people, and any equipment with perfect safety technical measures needs to be managed and maintained by people Therefore, in the final analysis, it is still inseparable from human factors, which is inseparable from the improvement of management and labor standards Personnel quality, safety awareness and scientific and technological level are the most fundamental security guarantees
