What are the reasons for the lower mounting power of the JUKI Mounter, Touch screen and OLED Forum
Some customers will find that the mounting power becomes lower after using the mounter for a period of time. Do you know what causes this? Now, let's talk about the mounter manufacturer.
here's a brief introduction: M! z0 l3 U8 E& w   Y2 J6 Q / G4 U "H1 E. I: y6 y (V # K 1). On the one hand, the suction nozzle of the mounter is lack of vacuum and negative pressure.
before taking parts from the suction nozzle of the JUKI mounter, the mechanical valve on the mounting head is actively changed from air blowing to true other adsorption, and a certain negative pressure occurs. When the negative pressure sensor detects the value within a certain range after drawing parts, the machine is normal, on the contrary, the suction is not good.

What are the reasons for the lower mounting power of the JUKI Mounter?

when the negative pressure sensor detects the value within a certain range, the machine is normal$ G. X# L* `# F$ F    d9 f6 I& V: Z) ]; y% E4 o* cOn the one hand, it is the pressure relief of the air source circuit.
for example, the aging and cracking of the rubber air pipe, the aging and wearing of the sealing parts, and the wearing of the suction nozzle after long-term use, etc., on the other hand, it is the dust in the adhesive or external environment, especially the large amount of waste chips after the cutting of the components of the paper tape packaging, which forms the suction nozzle plug of the SMT.

in order to improve the quality of the mounter, it is necessary to improve the quality of the mounter2 Z.

this situation can only be well controlled in terms of the quality of purchased SMT components.
this will not only affect the working power and product quality of SMT, but also cause different degrees of damage when the suction nozzle often sucks up the SMT components, which will reduce the service life of the suction nozzle overnight.
