A simple experience of solving a failure to start
Last night I was called to the workshop at midnight, almost fainted, funny and angry!
Fault phenomenon: 2060 cannot start, on-site technicians turned off and on several times, the fault still exists!
As a result, when I came over, it showed:
Non_system diskette
Replace and press any key to reboot 

 

Remove the floppy disk, press the confirm key, and start OK!
Problem point: The first disk for the computer to start is A drive, but the program cannot be found to start at this time!
So everyone must change the first boot disk back to C drive after doing GHOST!

 

The suction nozzle cannot be insertedATLProblem sharing!
A common problem we encounter when working with machines is that the vacuum cannot be raised and the filter needs to be replaced,Tools are very important,During a production machine nozzle change, I was unable to insert the suction nozzleATCIn,The operator returned the machine to the origin several times but it did not return automatically,I went over to take a lookATCThere was no suction nozzle,I touched the suction nozzle with my hand, it was still on the head, and when I took it off by hand, I found a problem. The small screw on the head was not tightened, and it rotated when the head rotated, causing it to be unable to return. I also saw some wear on the side of the suction nozzle. If the head falls off during the chip placement, the consequences would be unimaginable!
1. The screw was not tightened (possibly due to inadequate tools not tightening it), it rotated when the head rotated, causing it to be unable to return. Tightening it is OK.
2. When replacing the filter,The tool (hex screw) is very important. If it doesn't work, you can cut off the worn part of the tool and use it again. Everyone can try.
　　Hope this is useful to everyone.

Minor issue"When entering and exiting the board, substrate induction occurs."The solution!
In production with gaps.PCBWhen there are boards with larger gaps or spliced boards, substrate induction often occurs. The problem is not significant but can be very troublesome, especially for beginners. The solution is not difficult; in the machine settings, select the delay time or length in the substrate transfer. It is recommended to choose the delay length as it is better. This delay time or length is based on the gaps of the board and the spacing between the spliced boards.PCB.

2060Experience in solving nozzle collisions.

I encountered a situation like this before:
A machine2060collided with the nozzle during normal production, and the nozzles below were all broken.L3Head;
Stop the machine and check.L3 SHAFTand the nozzle head (including whether the screws are loose), normal; check.FEEDERand the program, normal; and swap withL4SHAFT, make sure to adjust it properly, and start production.During normal production, open the
COVERand observe for a few minutes. No problems were found. After about half an hour of production, another collision occurred, and the machine was stopped immediately.Is the thought process incorrect? After thinking for a while, I opened it again.
Check if there is any problem on the track.and observe for a few minutes. No problems were found. After about half an hour of production, another collision occurred, and the machine was stopped immediately.I found that there was a scratch mark on one screw. I took it down and compared it with other screws. This screw was actually a bit higher than the others (later I found out that it was because a previous screw had fallen off, and someone had found a similar screw to install, without considering whether the height was consistent).
Later, I found a screw of the same height to install for production, and it worked.

 

Experience sharing on the maintenance of the JUKI 2060 machine!
During production, the machine often freezes when it reaches the waste box, reporting errors on the X-axis, Y-axis, or Z-axis, unable to return to the origin. Each time, it has to be restarted, and sometimes when it returns to the origin, it reaches the waste box again, and the machine becomes unresponsive. One day, restarting the machine didn't help. Considering that there might be a problem with the optical ruler, the supplier came to help replace an optical ruler, and it was okay!

A problem that occurred during production last night, useful for everyone.
Last night, during production, one of our JUKI 2050 machines had a cover from the tank chain fall into the Y-axis belt. The operator was unaware and returned the machine to the origin, resulting in a loud noise and an inability to return, reporting a Z-axis drive error.

I have time today to share this reminder with everyone.
, when replacing a new tank chain, wrap the cover on each link of the tank chain with tape to prevent falling and causing wear or machine failure.
2. After using the tank chain for a period, it will have some movement. Place a spacer between the tank chain and the top (to prevent the tank chain from hitting the iron plate of the machine cover) and wrap it with tape to prevent the spacer from falling off, reducing the movement (friction) of the tank chain. This can extend the service life of the tank chain.
1Everyone often says that the service life of the tank chain is short, right? Following the above method can allow the tank chain to be used for about three years. This is also my experience in production with two machines: one wrapped and used for about three years, and one without wrapping used for about a year.
Now let's talk about

JUKI-2060MLaser fault repair sharing
Some time ago,CompanyFOne of the lines2060Continuously throwing materials during production,And when exchanging nozzles, there was also a question of whether to continue with the already installed nozzle.Stop the machine and check the laser in manual control,Found the laser was particularly dirty,No matter how I wiped it, it wouldn't come off,So I shut it down and restarted,Returning to the origin is normal.Checked again and it actually worked.Normal production for less than ten minutes,The problem came again. It was inferred that there might be a problem with the laser,Removed it andELine2060SHAFT,Adjusted the laser teaching,Produced normally again, observed. After producing for more than ten minutes,FThe line encountered the same problem again,EBut the line was normal, and the laser was fine. It must be a problem with the laser control board, so I took down the control board, and the board was very dirty! It was full of dust, so I found an air gun to blow it clean, then reinstalled it, produced normally, and observed for more than an hour without any problems appearing again.Shaft error, failed to return to the origin.!
Also, this machine was only bought a little over two years ago, and the cleaning staff in the workshop have to mop the floor two or three times a day. I don't know where all this dust comes from. I don't know if it's a design issue with the machine or something else. I wonder if other companies have this phenomenon as well. It could be that too much dust causes short circuits and burns the board. I hope my colleagues can also provide good suggestions so that we can work together to solve and overcome the dust prevention issue.

KE2055Strange problem handling experience sharing
KE2055During the production process, when throwing materials, there was a failure to discard components,CheckLASER,Component data,NOZZLE,There are no issues,CheckMSParameters,Swap.MSParameters(UsingJUKIFixture)There will still be the same alarm,There was no way, so I brought this machine and input the parameters from when it left the factory to produceOK.

JUKI KE2050Hard disk damage repair (English)
1.Red glue quantity for one IC: 2 points.
Because there is some space between IC and PCB.
When the chip component IC is soldered in the dip machine.
The solder may flow to the copper pad under the IC 
just like in the right drawing, which will cause solder short to happen.
2.Red glue quantity for one IC: 4 points.
There is very small space between IC and PCB because of having 
much red glue under the IC, which will prohibit the soldering from flowing 
into the copper pad under the IC and prevent the solder from existing under IC.

JUKI repair experience sharing

Some time ago, during the production process, the machine did not alarm and there was a collision, hittingXthe left or right side of the axis. Restarting the machine for production caused the same problem again. Those who have seen it know that the machine has collided, while those who haven't think it's thunder and about to rain. Fortunately, nothing was damaged, otherwise it would have been troublesome.
1. Start from the simple, analyze that it only collided in the X-axis direction and did not collide in the Y-axis direction. Restart the machine to return to the origin, move the X-axis back and forth in manual control, no abnormalities; then preheat the machine for 10 minutes, no abnormalities.
2. Open the machine cover underneath, plug in all the visible interfaces once. When plugging in the wires on the XMP board, the problem was found: the XMP board was loose. Tighten the XMP board and screw it tight. Restart the machine, and it has been over a month without any collisions.
