See some more than a dozen processes, dozens of equipment in that orderly operation. The bar codes of different styles, the colorful signals on the measuring equipment dazzled me, and I didn't know where to start. Later, I consulted master, and master told me a sentence that I still remember: "Is the assembly line good? Focus on preventing mistakes." So here's the question.

How to avoid mistakes in fan production line

Many customers through our website to call to consult the fan production line to avoid error prevention should do, then xiaobian * to explain the fan production line to avoid error prevention should do. I want to talk about error prevention.


Look at the dozens of processes, dozens of equipment in that orderly operation. Different types of bar codes, measuring the color signals of equipment to see dazzling, not knowing where to start.


After a discussion with my teacher, THE teacher told me a line that I still remember, "Is the assembly line good or bad? The emphasis is wrong." That's the problem.

First, what is error prevention?

Error prevention, Japanese called error prevention, English called error prevention or fool prevention.

Why is Japanese mentioned here? I'm sure those of you in the automotive industry have heard of Toyota's "Lean Manufacturing", the concept of boca yoke -- the initiative of Shingeo Shingo, the Japanese quality management expert and founder of Toyota's production system. Literally, preventing errors means preventing errors from happening. To really understand error prevention, let's first look at "mistakes" and why they happen. "Mistakes" lead to deviation from expectations and may eventually produce defects, which are mainly caused by people's negligence and unconsciousness. For the manufacturing industry, we are most concerned about the production defects of products, which may be caused by the "man-machine material method". Human error not only exists and cannot be avoided, but also affects factors such as machines, materials, methods, environment, measurements, etc. (after all, things are done by people, not independently), such as adding wrong materials. Thus was born the concept of "error-proofing," which is largely about fighting people (we don't usually talk about equipment and materials going wrong).


What are the causes of human error?

Someone has come up with a list of top 10 reasons mistakes happen, and I'll share it with you. They are: forgetfulness, understanding, recognition, newness, willfulness, negligence, obtuse, lack of standards, accidents, intentional errors.

Forget: When we don't pay attention to something, we forget something. For example, Mr. Tang just lost his mobile phone. We often learn new things from previous experience. For example, we always think we won't go to work this Saturday.

C. Identifying errors: * Errors occur when you read too fast, too slow, or not carefully enough.

D. Novice mistakes: inexperienced mistakes, such as older employees making fewer mistakes than new employees.

E. Willingness error: The mistake of deciding not to follow certain rules at certain times, such as running a red light.

Careless mistake: an absent-minded mistake, such as accidentally crossing the street without noticing that the red light is on.

G. Slow error: misjudgment or slow motion, such as slow braking

H. Errors caused by lack of standards: No rules, no standards

I. Unexpected error: an error caused by an unconsidered factor, such as a failure of an inspection device.

J. Intentional error: It is not good for people to make mistakes on purpose.

These categories are a little bit fragmented and there's a lot of overlap. But it's just a matter of skills, rules and knowledge.

If you want to xiao Tang teacher summary, can consider the cause of these reasons, it is the inertia of people.

Humans are inherently lazy, so the easier, lighter, and more unconscious a task is, the less likely it is to make a mistake.

This is the key to preventing mistakes.


Third, what are the production consequences of these mistakes?

Many examples of mistakes are examples from life. After all, our public numbering is a lot of manufacturing services, so let's see what these errors can lead to in a particular manufacturing process. No matter what part is produced, these errors can have the following consequences on production:

A. Lack of procedures

B. Homework errors

C. Workpiece setting error

D. short

E. Part error

F. Workpiece processing error

G. Operation error

H. Adjust for error

1. Improper equipment parameters

J. Improper fixture

If we relate the cause and effect of the error to the row, we get the following figure.

After analyzing the causes and consequences, we should begin to solve them.


Fourth, the concept of error prevention

For a long time, the main means of preventing human error is "training and punishment". Extensive training has been given to operators, who have been admonished by managers to be serious, diligent and "quality-conscious". When mistakes are made, they often take the form of "pay cuts" and "bonus deductions". However, mistakes caused by human negligence and forgetfulness are hard to avoid. The combination of training and punishment has not been successful. A new error-proofing approach, through a set of equipment or methods, enables the operator to directly detect or avoid defects.


The above * is xiaobian for you to sort out the fan production line related consultation, through the sharing of this content, we have a certain understanding of the fan production line, if you want to have a deeper understanding of the market information of the fan production line, you can contact our company's salesman, or to visit the field, to discuss and exchange. http:///
