| Phenomenon | Cause | Solution |
| Wrong detection of glass size | a. Sealing robot is not even with insulating glass production line b. Glass is dirty | a. Adjust the sealing robot to be even with insulating glass production line also the belt height b. Clean the glass ,there should be no label where the sensor detect |
| Sucker can not suck the central of the glass | a. wrong detection of glass size b. set wrong parameters | a. Adjust the sealing robot to be even with insulating glass production line also the belt height ;Clean the glass ,there should be no label where the sensor detect b. Reset parameters |
| Extruding head touch glass when go upward | Glass to sealant nozzle distance | Increase the figure of “glass to sealant nozzle distance “ |
| Extruding nozzle can not touch the first size of glass when extruding sealant | a. low air pressure b. glass to extruding nozzle distance | a. Increase air pressure b. decrease the figure of “glass to sealant nozzle distance “ |
| Extruding nozzle can not touch the second size of glass when extruding sealant | a. high air pressure b. upward sealing distance | a. Decrease pressure b. Decrease “upward sealing distance “ |
| Extruding nozzle can not touch the third size of glass when extruding sealant | a. low air pressure b. upper sealing distance | a. Increase air pressure b. decrease the figure of “upper sealing distance “ |
| Extruding nozzle can not touch the forth size of glass when extruding sealant | a. low air pressure b. downward sealing distance | a. Increase air pressure b. Inecrease the figure of “downward sealing distance “ |
| V type belt | a. deviate to inside b. deviate to outside | a. adjust zero sensor outward b. adjust zero sensor inward |
| Hydraulic station | a. no pressure b. lower than the set pressure | a. set the pressure b. increase the electric current on the mix controller |
| Sealant is not full on one side of the glass | a. check the sealant pressure b. aluminium spacer is not in the right location c. the scanner do not detect the central of aluminium spacer | a. increase the black sealant pressure b. the sealant can not go into if the aluminium spacer is not in the right location c. vertical beam is not parallel with board or is not vertical with belt ,adjust the parameter of head front/back |
| Sealant break on each side of glass | a. Mixer is block b. The frame is even | a. Clean the mixer b. adjust the parameter of head front/back |
| The extruding head can not move after turning corner | a. the scraper not scratch well b. scraper sensor detect wrong | a. check whether the scraper is lubricate ,adjust the scraper pressure - adjust the magnetic switch of the two cylinder
|
| The first side sealant is not full | The mixing sealant pump is not full with sealant | Increase A sealant pressure |
| Sealant is not full before the corner | The close distance advance is large | Decrease the close distance advance |
| Sealant is not full after the corner | time of valve open delay is long | Short the time of valve open delay |
| Sealant is not full on the corner | Pulse extruding sealant is small | Increase the time of Pulse extruding |
| Sealant can not come | a. sealant pressure b. sealant without pressure | a. check the pipe under mixer b. check the pipe before mixing pump |
| The sealant pump can not extrude sealant | a. the sealant pressure higher than 8Mpa b. sealant pressure is lower than 2Mpa | a. discharge sealant to low pressure by hand b. check whether the sealant mouth is block on the platen ,check the filter of the black sealant |
| Hydraulic station do not work | a. the mixing pump do not touch the lower limit b. hydraulic station motor contactor | a. higher the location of lower limit b. check the hydraulic station motor whether work well |
| Servo motor alarm | a. Alarm code A810 b. Alarm code AC90 c. Alarm code A95 d. Alarm code A910 | a. there is problem with battery of the small motor ,reset with computer b. there is problem of encoder c. servo contactor do not touch d. motor overload |
| Do not turn corner after the second side | The glass do not move together with the belt | The extruding head press the glass tighten ,adjust the pressure |
