Maintenance and key points of SMT Mounter

Smt Key points for the maintenance of the mounter

SMT machine ： also called “ Mounting machine ”、“ Surface mount system ”(Surface Mount System), In the production line , It is configured after dispensing machine or screen printing machine , It is to place surface mounted components accurately by moving the mounting head PCB A device on a pad

SMT The mounter is SMT The core automation equipment in the process , It is a highly automated production equipment , It is equivalent to a patch robot . For this kind of high-precision production equipment, it must be regularly and correctly maintained ,smt Chip processing manufacturer , The chip mounter is the rice bowl for eating , So how to maintain SMT SMT machine , It is a problem that must be considered .

How to maintain the mounter ？

1、 Check the buffer action of the suction nozzle clamp , If the action is not smooth, apply a thin layer of lubricant , If the clamp is loose , Fastening .

2、 Move the lens to clean the dust and residues on the lens . Check Y Axis 、X Shaft lead screw check the lead screw for debris or residues , Clean if necessary .W Shaft lead screw check the lead screw for debris or residues , Check the clean air interface if necessary Y O-rings and O The O-ring is aging , Replace if necessary .

3、 The monthly inspection of this part shall be carried out according to the type of nozzle and the nozzle changing station .

4、 Nozzle shaft inspection is used for each nozzle shaft O O-ring , Replace it in time in case of aging .

5、X The spindle screw wipes away dust and residues , Apply a thin layer of grease by hand .

6、Y Remove dust and residues from the shaft guide , Apply a thin layer of grease by hand .

7、Z Check the action of the shaft rack and gear , Apply a thin layer of lubricant to the rack drive components by hand if necessary .

8、R Check the wear and tightness of the shaft drive belt , Replace the belt or adjust its tightness if necessary .

9、W The spindle screw wipes away dust and residues , Apply a thin layer of grease by hand to the feed valve to check whether its solenoid valve can work normally . Check the belt for wear and tightness , If necessary, replace the belt or adjust its tightness .

10、 For the maintenance of the chip mounter, the dust and scale on the surface of the machine and the circuit board shall be cleaned and removed , In order to avoid poor heat dissipation inside the machine due to dust and dirt , Cause electrical parts to overheat and burn out .

11、 For the internal air circuit of the chip mounter 、 Solenoid valve 、 Vacuum generator 、 The air cylinder shall be disassembled and cleaned to a certain extent . If the oil dirt in the gas circuit cannot be cleaned in time , In that case, the gas circuit will be blocked , Thus, the air path will be blocked , Cause high throwing ; Even the oil stains that may accumulate in the air circuit will corrode the solenoid valve 、 Vacuum generator 、 Cylinder and other internal sealing rings and components , It will cause damage to the components .
