What are the requirements for the focus of the implementation of visual management in SMT factories

(1) Express management requirements

Confusion in management is often caused by employees not knowing the management requirements. The management requirements are visually expressed through visual management, so that employees can grasp them clearly and then consciously abide by them. Explicit management requirements are a main content of visual management, and are the most widely used in visual management. Various expressions such as prompts, warnings, specifications, regulations, requirements, etc. in the workplace are all statements, signs, graphics, line drawing, etc., which all belong to the content of express management requirements, such as "No fireworks" I sentence, escape above the door Direction indications, male and female figures on the bathroom door, line drawing on the floor of the production area, etc. There are such explicit management requirements in the production site of each factory, but the visual management requirements will make the explicit management requirements standardized, clear, beautiful, and thorough.

(2) Let it be clear at a glance

Making it clear at a glance means that anyone can judge whether the situation is normal, and the judgment result will not vary from person to person. If people do not know the scene, they cannot judge whether the situation on the scene is normal, and visual management loses its meaning. Therefore, the requirement for the implementation of visual management is to be understood by laymen. For example, if you want to know the pressure in the water pipe, you can install a water pressure gauge, so that you can read the water pressure value through the water pressure gauge, and professionals can judge whether the water pressure is normal based on the reading. However, although other personnel can read the data through the water pressure gauge, they do not know whether the water pressure is normal. If the normal range of water pressure is marked in green and the abnormal range is marked in red on the water pressure gauge, everyone can judge whether the water pressure is normal. For the implementation of visual management, just reading the data is not enough, the key is to be able to judge at a glance whether it is normal or not.

(3) Depicting the ideal state

Depicting the ideal state is to make the goal clear. Without a clear goal, the data and conditions we reveal are meaningless. If we want to reduce the mold change time of a certain machine tool, it is required to reduce it from the current 6 hours to 2 hours in half a year. In this way, we set up a reminder next to the machine tool, mark the current mold change time and the mold change time in half a year on the graph, and then draw a straight line between these two points to indicate the goal that needs to be achieved each month value. Every time the mold is changed, the time is measured and then marked on the graph. After a period of time, we found that the actual mold change time began to follow the target straight line. This was because the operator had an understanding of the target and worked hard. Once the mold change time jumps above the target line, you know that the improvement is not enough and you need to take action to avoid this situation again in the future. This is the effect of visual management, that is, by depicting the ideal state, making the goal clear, and thus motivating employees. Simply marking the data and status is not enough to motivate employees. Without the target value, the data and status are lifeless things.

(4) Simplify the operation

For many complex and tedious daily tasks, you can consider the application of visual management to simplify operations, which not only improves work efficiency, but also avoids errors. A factory's visual management of the generator room has achieved the effect of simplifying operations. When several engines in the generator room are started, it is necessary to record the various operating parameters of each generator every half an hour, and the operation time for each parameter recording is about one. minute. Later, they implemented visual management of the generator room. First, mark the location of each point that needs to be checked and recorded on the generator. At the same time, set the normal and abnormal range of pointers for all instruments that need to be recorded. When recording, it is only necessary to confirm whether the pointer is within the normal range, and it is not necessary to record the specific value pointed by the pointer. In addition, a spot inspection channel is set up. When performing inspection and recording operations, you only need to walk along the spot inspection channel to complete the inspection record of the generator operating parameters. Through these measures, the operation of recording generator operating parameters has become much simpler, and each operation only takes 2 minutes.

(5) Remind attention and avoid forgetting

Applying visual management to reveal the working status can serve as a reminder and avoid errors caused by forgetting. For example, we use various forms in our work, and these forms may be placed in a file cabinet. It may often happen that when we have used up a certain form, we may realize that we should copy the necessary amount of stock of this form before it is all used up. If we put the original of this form at the end and put a reminder paper for copying before the original, we can avoid the situation that the form is completely used up. For another example, some consumables of machinery and equipment need to be replaced regularly, such as lubricating oil, filters, belts and so on. If we can set up a notice board next to the equipment to indicate the last replacement time of the consumables and the next scheduled replacement time, we can avoid possible damage to the equipment due to the failure to replace the consumables on time.
