点胶量的胶量不均匀出现的原因?

些小问题。那么手机的胶量忽大忽小是什么原因?下面一起听一听技术人员是如何分析的吧?
  With the development of science and technology, industrial automation production is becoming more and more popular, dispensing machine plays an important role in industrial automation production. Although dispensing machine brings us great convenience in industrial production, dispensing machine will inevitably present some minor problems in the process of dispensing. So what's the reason why the glue volume of dispenser is too big or too small? Now let's listen to how the technicians of Aosong Automation analyze it.
  气动式手机节制电磁阀的开启/封锁可以调节点胶时间的长短,借助减压阀可以调节储气罐中的压力巨细,点胶时间长短和储气罐中压力的巨细会直接影响胶滴的体积与形状。
  Pneumatic dispensing machine can control the opening/blockade of solenoid valve to adjust the dispensing time. With the help of pressure reducing valve, the pressure in the gas tank can be adjusted. The length of dispensing time and the pressure in the gas tank will directly affect the volume and shape of the rubber droplets.

  经由过程选用内径合适的手机针头(小内径为60 um),并节制气压和电磁阀的接通时间,亚洲时间—压力型手机能获得相当一致的微胶滴体积和形状。
  By choosing the needle of dispensing machine with suitable inner diameter (small inner diameter is 60 um), and controlling the connecting time of air pressure and solenoid valve, a time-pressure dispensing machine is used to obtain a fairly uniform volume and shape of the microdroplets.
  在气动式点胶过程中,开始时手机针筒内装满胶液,跟着点胶过程的不竭进行,针筒内的胶液体积逐渐减少,气体体积不竭增加,在同样的点胶时间和压力下,手机点出的胶体量会逐渐减少。所以,针筒内的胶量和空气体积为时变参数,点胶过程是一时变大都动态系统,系统动态特性随时间变化而变化。此外,空气又有可压缩性,因此手机点胶量的精度和一致性难以节制。
  In the process of pneumatic dispensing, the needle barrel of dispensing machine is filled with glue at the beginning. Following the continuous dispensing process, the volume of glue in the needle barrel decreases gradually and the volume of gas increases continuously. Under the same dispensing time and pressure, the amount of glue produced by dispensing machine decreases gradually. Therefore, the rubber volume and air volume in the syringe are time-varying parameters. The dispensing process is a time-varying dynamic system, and the dynamic characteristics of the system change with time. In addition, the air is compressible, so the accuracy and consistency of dispensing quantity of dispensing machine is difficult to control.
