Smontaggio avvitatore XIAOMI Mijia Precision (Disassembly and reassembly screwdriver)

- เผยแพร่เมื่อ 28 ก.ค. 2022
- Purtroppo al primo utilizzo, dopo aver svitato le prime tre o quattro viti di un notebook che avevo in riparazione, il mio nuovo avvitatore XIAOMI Mijia, si è danneggiato. Un ingranaggio, forse difettoso, ha perso un paio di denti rendendolo inutilizzabile. Non avendo trovato in rete una guida che illustrasse come smontarlo, dopo averne ricevuto uno nuovo in sostituzione, ho deciso di sacrificare quello guasto per realizzare questo video a scopo divulgativo nella speranza che possa essere utile a qualcuno.
Sappiate comunque che è assai probabile che durante lo smontaggio si romperanno le due linguette in plastica lato porta USB. - แนวปฏิบัติและการใช้ชีวิต
Had mine lying around in my tool box for a long time, though not because the screw driver itself actually worked. I just kept it because of the tool bits and aesthetics i guess. Anyway i today decided to clean up a bit inside my toolbox, also meaning repairing broken tools. When i opened the screwdriver seen in this video, i firstly realized that the battery was completely dead, though that is caused most likely from the fact that the screwdriver had lied in the tool box for years, with a completely dead battery. That being said, a dead battery is most likely not what has caused your issue. I might be a bit ignorant on the topic, but if you want to fix this specific type of screwdriver, with the problem seen in the video (weird sound or and stuck when turned), then good luck my friend, because your gonna need it. The small dc motor is attached to a series of gear reduction spur gears, and as i looked onto the gears i could see with my bare eyes that the upper most gears where completely fuc*ed🤣. So there you go, if you want to fix this issue, go get some new spur gears🤣. Good luck mate😉
Thanks friend
As mentioned in various comments, back when the video was made, I purchased and replaced the gear assembly for just a few euros. It was easy-peasy! 😉
@@claudiobelli9842 That's awesome, how does the screwdriver hold up now? Is it the same gear that seemingly easily breaks or did you buy some upgraded version?
Ottimo tutorial. È difficile trovare batterie al litio sostitutive per questo cacciavite? Sembrano più piccoli del 18650.
only with his fingers? the demons under the bed are scared of this dude for sure
😄😄
You're funny. Don't worry, demons don't fear me and I don't fear them. I have no interest in deceiving people. When I decided to make the video, I had already disassembled it, so it was easy to open it with only my fingers. It seems quite obvious to me! As I have already said in the description, the video is purely demonstrative, it only serves to help ..
Nel mandrino che fai vedere nel minuto 2:31, ci sono 2 o 3 rullini all'interno? Mi è caduto e ho paura di averne perso uno.
I think i broke the motoreductor, do you know the reference of the one used inside the screwdriver?
N20
@@ANTI-MOSHENNIK I tried to find a motor reducer of the same capacity as you wrote N20, but there are many options on aliexpress(( How do I know exactly which motor reducer is inside this xiaomi screwdriver? That is, I need to know how many volts? 3v, 6v or 12v?
Bro my motherboard was broken where do i get it
I wrapped with cloth insulation tape, pulled it with a plier. Phewwwh what a pita to remove the cap. The built quality is impressive tho.
Hello should i replace the motor with a 100, 150 or 200rpm motor
buy low rpm so it has more torque
I have the Xiaomi branded one at work and the Mijia at home, both brand new, same finish but different sound 😅😮
i didnt charge it for a year and now it wont even charge , the red light comes for a second when i plug in the usb cable but then goes away , is there a problem with the battery or with the usb pin ?
if we want to change the battery can you please post a video on how to do it ? or to change the usb pin
same issue
You can see in the video it's a 3.7V 350mAh Li-ion ICR 10440 cell. Tried to post a link, but if you search ICR10440 you should find it!
where can i find this broken mechanism? i checked outside mechanism but i couldnt see anything number or code
Topic already covered. Read the answers to "Riccardo Fedeli"..
Is it well constructed? What do you think about its motor and durability? I'm not a eletronic guy
Yes, it is a well built product. The materials are also good considering the price. You just have to be careful not to use it with too much force, otherwise you risk breaking the gears as happened to me while I was unscrewing the screws of a notebook .. For this reason I think it is only suitable for smartphones or something similar.
I have the same problem (Please tell me if you managed to fix it? Did you replace the entire gear motor? If so, please tell me the model so I can also find it and get a tool to repair my screwdriver... Thanks
Yes of course, I replaced the gears keeping the original engine because it was of superior quality. Read in the comments, I also indicated the links. check if they are still valid.. have fun
@@claudiobelli9842 I couldn't find the links in your comments or in the description below this video(
Can you please tell me where you ordered the gears for this motor reducer?
Did you order them from aliexpress? if so, tell me what they are called by name so that I can also order for myself))
@@claudiobelli9842 Model N20 200 RPM 3v?
@@RaccoonTech In the comments it says..
Anyway I got it here. I took the 150rpm version but it's a little fast, so I recommend the 3v and 100rpm version. Furthermore, I also advise you to replace only the gears and keep the original engine because it is of superior quality. So actually when you buy the voltage it doesn't matter. Remember that you will also need to shorten the tree to the right size.

@@claudiobelli9842 This link you left in the comments is a slightly different gear motor, it has a longer tip. But I found the same one with the same dimensions that should fit perfectly. And yes, I will replace only the gears, and I will leave the motor original.
what is the correct way to remove it? My screwdriver is too hard to remove

MERCI
Prego!
how do you open the cap? it's so fit that can't open by using my hands.
I had the same problem, I removed it with a clamp and a cloth
@@espacefiguratif It's a challenge, I am not a good master, but anyway how :) Are there any lockers inside which I need to push firstly?
Ok. I've done it. The redactor is broken.
@@MrPartysun Я так понял, ты уже пытался разобрать такую. Это возможно сделать не ломая крепеж на крышке? Или там никак? И если никак, что потом с ней происходит? Не слетает сама по себе?
@@MrPartysun так как открыли то?
where I can find battery for this xiaomi screwdriver?

Thanks!
I broket the motor of my screwdriver, you know where I can find it?
BTW: thanks for the video
Search the Aliexpress site for "n20 dc geared motor". And be careful to choose the one that's right for you.
Did you find a right motor?

Look in the answers to "riccardo fedeli".

Could you tell me where to buy the engine?
Hi,
if you look the earlier messages, you'll find the link where I bought the spare parts. Just keep in mind that they date back some time ago..
Ciao scusa il disturbo sai per caso di preciso che motore è ? Quanti volt, amps e rpm ha per orientarmi sull'acquisto su aliexpress ?
Ciao
Premesso che non ho ancora acquistato il motoriduttore di ricambio per il mio, il motore è da 3V e, misurato, il mio ruota a 168 RPM. Quindi acquisterei quello che più si avvicina ovvero il 200 RPM.
Mi correggo, ho visto che ci sono anche quelli da 150 RPM..
@@claudiobelli9842 come hai misurato gli rpm ?
@@riccardofedeli4711 Con un tachimetro digitale, ma esistono anche altri modi efficaci anche se meno pratici. Io, ad esempio, ho utilizzato per molto tempo le registrazioni audio digitali importate in programmi con una timeline tipo Premiere.
@@claudiobelli9842 te lo chiedo perche cercando su aliexpress non c'è nessun motore da 3v con 150rpm circa che abbia le prestazioni dichiarate da xiami nel mijia screwdriver
What type of battery does it use?
a normal 3.7v battery

Хватило ровно на один разбор ноутбука. Стерлись шлеци редуктора.
Никому не советую данную отвертку, предыдущая модель в разы лучше.
listen to the boss,,,,, don't forget to stop by for black coffee together... goes duit so that you will increase your enthusiasm for work and add brothers thank you very much
Thanks!
El motor es como de los juguetes
Still recognizable and notorious Chinese quality. Especially these broken pieces in the beginning. No, thanks a lot, I will pay more for something better
I barely even used this and the battery stopped charging...
