1.SMT machine cylinder
The cylinder in the mounter is generally used in combination with the solenoid valve, playing the role of lifting and stopping. In the structure of the placement machine, the cylinder is used very widely, such as the chip head cylinder can be used on the chip head is not set to stop the role; chip table rise and fall, the cylinder according to the signal of the solenoid valve to stretch the table rise and fall.
Chip machine cylinder use process will have wear and dust entry, should be regularly checked, once the problem is found immediately, if the compressed air is not clean cause cylinder expansion inflexible or not in place, we must immediately clean; if the air leakage, it may seal aging, then to replace the seal, if the piston wear, then we must replace the cylinder.
2.Pick and place machine filter
SMD machine filter in the placement process plays the role of compression and filter pressure, to ensure the cleanliness of the air shrinkage gas, if the filter is defaced, then the filtering effect is not good, will affect the suction nozzle suction, thus directly affect the effect of placement. In the maintenance of the patching machine, kind of regular replacement of the filter habit, generally replaced once a month, belongs to the consumption of accessories. Therefore the mounter filter to have a certain number of spare parts.
SMT machine reflection cap and reflection plate
SMD machine reflection board is used for the detection of component electrode size and nozzle number. When there is bad recognition in the bonder process, the reflector plate and reflector cap should be checked or replaced.
3.SMT machine bearings
The bearing on the mounting machine plays two roles
First, limit, bearing limit is to be fixed axis can only realize the transformation, and can not be axial and radial movement;.
Second, support, support refers to bear the radial load of the shaft. Bearing according to the function is divided into rolling axial heart bearing, ball bearing and thrust bearing, etc.. Bearings are widely used in the structure of the mounter standard parts, it requires smooth operation, if long time running, there will be wear and tear, to be inspected regularly, found that the bearing has radial faltering, affecting the normal operation of the equipment, immediately for replacement. Such as chip machine in the use of joint bearings and rolling bearings.
4.Mounting machine synchronous belt
Synchronous belt is composed of a surface with equally spaced teeth of the ring belt and the corresponding coincident wheel. It combines the advantages of the belt drive, chain drive and tooth drive each. When working, the power is transmitted by meshing the teeth of the belt with the tooth grooves of the wheel. Synchronous belt drive has an accurate transmission ratio, can obtain a constant speed ratio, no slip, low noise, smooth transmission, can absorb vibration, transmission ratio range, generally up to 1 to 10, allow linear speed up to 50m / s, transfer power from a few watts to kilowatts. Transmission efficiency is high, generally up to 98%, compact structure, suitable for multi-axis transmission, no pollution, no lubrication, so it can not allow pollution and work in a more hostile environment under the normal workplace.
5.SMT machine conveyor belt
Conveyor belt is used for the transmission of placement products. Conveyor belt in the long-term use process will appear wear phenomenon, wear to a certain extent will break. SMD machine conveyor belt at least need to prepare a copy, for some often wear more serious parts may have to prepare two copies.
Any kind of accessories on the chip machine damage will affect the normal efficiency of the chip machine, so the regular maintenance of the chip machine at the same time to set the chip machine accessories for inspection and repair and replacement.
Zhejiang NeoDen Technology Co., Ltd. has been manufacturing and exporting various small pick and place machines since 2010.
