Multi axis linkage manipulator is important parts of the dispensing machine irregular dispensing work, the general bearing part of mechanical arm to ensure adequate lubrication degree can be more flexible to work, need long-term implementation of multi axis dispensing work, so the work bearing part may be due to friction noise and the influence of mechanical arm fluency. The mechanical arm moving guide part of the noise but also because the reasons for friction, the operator must regularly remove attached to the plane of the foreign body such as dust, then add lubrication oil is necessary to improve the effect of the actual work. The number of online multi axis pneumatic drive mode has glue dispensing machine certain noise, mainly producing high pressure air compressor and the inner wall of the collision noise, when the noise energy gives us some information, such as the air compressor production pressure is too high or not stable, have a certain influence the stability of the situation the dispensing work, to perform on-line dispensing work, can be appropriate to reduce the air compressor works, of course, can be placed to reduce the impact of noise caused by vibration of cotton. Multi axis online dispensing machine can further improve the working effect by carrying the pipeline. In order to avoid excessive noise in dispensing, regular maintenance should be carried out regularly.
