One of the ideas of lean production is to use all methods to eliminate and reduce all non-value-added activities, such as checking, processing, and waiting.
The specific method is to implement a "zero maintenance rate", and some of them must be qualified.
Do a good job at one time, and more importantly, prevent unqualified parts and raw materials from flowing into the subsequent production process at the source of production, and achieve zero scrap rate.
This is basically the same as the "3C website quality Management Law", we should continue to use the "3C", and reasonably reduce the time of "three confirmations" in the "3C" to further improve the "3C".
In order to improve the overall efficiency of the household appliance assembly line, the high-precision equipment of the manufacturers of the household appliance assembly line has been continuously invested in the household appliance assembly line.
However, the increase of these devices is improving production efficiency and indirectly leading to an increase in equipment maintenance costs and difficulties in changing household appliance assembly lines.
In many cases, inputs and outputs fall short of expectations.
In the production process, all the small amounts of materials, equipment, manpower, space and time necessary to increase the value of the product are wasted.
Therefore, waste refers not only to activities that do not add value, but also to the use of resources that exceed "very small" limits.
All kinds of waste are common in all enterprises.
In order to eliminate waste in the enterprise, it is necessary to first find the place of waste, and then find a way to solve the problem.
The common wastes in enterprises are as follows:
1.Disposal of waste.
Excessive processing and high machining accuracy: the actual machining accuracy is too high, resulting in a waste of resources; it requires more time and equipment to increase the waste of electricity, air pressure and other energy, as well as the use of labor.
2.Waste of bad maintenance.
The occurrence of defective products in enterprises requires a waste of time, manpower and material resources to dispose of, and cause corresponding losses.
3. Wasteful action.
Wasteful action is common in many companies' home appliance assembly lines.
The common action waste mainly includes the following kinds: doing nothing with both hands, doing nothing with one hand, sudden cessation of work exercise, excessive work exercise, "state" change in exercise, and so on.
The waste of these actions results in unnecessary time and physical exertion.
Especially in recent years, enterprises are developing and debugging new products faster and faster, which puts forward higher requirements for flexible production.
However, each traditional household appliance assembly line of household appliance assembly line manufacturers is expensive and difficult to adjust, which makes it impossible to meet this demand.
