NXT error code "8000D701"
Starting today, a series of copywriting related to FUJI NXT error codes will be launched one after another, but it will not involve some deeper electrical circuit knowledge, mainly the alarms that are often encountered in daily work, which has more extensive learning significance. Beginners play a greater role. Let the friends who have just come into contact with NXT to understand and understand faster. From the most basic and basic level, try to introduce to everyone in a "shallow in and deep out" way, I hope that everyone can pay more attention to the daily details, see the micro-knowledge, and accumulate steps to a thousand miles, from quantitative change to qualitative change.
FUJI's error code (Error code) includes quite a lot of content, covering a wide range of content, and I believe that no one can explain all the code clearly. Therefore, a small questionnaire will be done later. "You most want to I understand the NXT error code", I hope you will actively answer. Since the editor has sorted out the code related to throwing, the first batch will start with the throwing aspect.
 
Let's start with the introduction of "8000D701". This code is the most common in work and does not accept any rebuttals. Since it has been encountered the most times, it may be the easiest for everyone to deal with.

1. The first half of the sentence "Please confirm whether the suction is wrong (no component), that is, due to various reasons, the suction nozzle did not suck the material normally.
2. The second half sentence, "the size described in the shape data is very different from the size of the component absorbed", this description is more worthy of scrutiny, if there is a problem with the size in the shape (Body XY, etc.), it is normal In the case of absorption, why not alarm the image processing abnormality? Why is the problem of shape size also classified as the 8000D701 that failed to be absorbed?
In the new product stage, before the programmer sees the actual material, the programmer will generally specify the most ideal PD based on experience, and of course the wrong shape and size parameters will be set into the program. At this time, if the size deviation is too large, the component The camera can't even find the outline of the material. It is completely logical that the device alarms "8000D701" for failing to absorb normally.
 
The following categories explain the reasons why the components cannot be absorbed:
 
Material problem: The material tank is too large. When feeding, the material moves back and forth in the tank, and the position is unstable, which makes it impossible to suck; the viscosity of the material film is large, and the material is taken away by the material film during feeding, and the suction nozzle cannot be sucked.
Feeder problem: the stepping is unstable and the suction position cannot be reached; or the feeder height is abnormal, and the suction nozzle in the Z direction cannot reach the material.
Suction nozzle problem: the suction nozzle is blocked, there is no vacuum or the vacuum is insufficient; the suction nozzle is damaged and leaks, resulting in insufficient vacuum; the selection of the suction nozzle is not optimized, and the nozzle model needs to be reset.
Screw rod problem: The screw rod is not smooth and needs lubrication and maintenance; the rod is deformed, resulting in a decrease in accuracy. It is necessary to calibrate the accuracy or hit PAM, or replace with a new rod.
Accuracy problem: due to the inability to absorb due to accuracy problems, most of the time, the placement quality should be abnormal first, and then it is found that the absorption is not possible, because the accuracy problem is often not a rapid accuracy drop (except for impact), but after a long period of operation , Accuracy decreases a little bit, throwing materials slowly increase, and the quality of placement is also slowly decreasing. In the end, "overwork becomes sick" and all burst out at a certain point in time. When it is confirmed that there are no problems with other items, recalibrate Or hit Pam and other corresponding countermeasures to improve accuracy.
