自动点胶机液料点胶的注意事项

点胶是一种工艺,是使用自动点胶机把电子胶水、油或者其他液体涂抹、灌封、点滴到产品上,让产品起到黏贴、灌封、绝缘、固定、表面光滑等作用,常见的应用领域包括,汽车电器 ,包装 ,家用电器,轴承,线路板,电子元件,药剂,电器组件,电容器,仪器,珠宝,石英晶体,集成电路,灯饰,手机,无线电设备,电线连接器,半导体封装,PCB电子零件固定及保护,LED玻璃机板封装粘接,移动电话机板涂布或按键点胶,扬声器点胶。。。
Dispensing is a process, is the use of automatic dispensing machine to apply electronic glue, oil or other liquid smudges, potting, drip to the product, so that the product plays the role of sticking, potting, insulation, fixing, smooth surface and so on, common applications include, automotive appliances, packaging, household appliances, bearings, circuitboards, electronic components, pharmaceutical, electrical components, Capacitors, instruments, jewelry, quartz crystals, integrated circuits, lighting, mobile phones, radio equipment, wire connectors, semiconductor packaging, PCB electronic parts fixing and protection, LED glass panel packaging bonding, mobile phone board coating or key dispensing, speaker dispensing...

今天就来说说自动点胶机液料点胶的注意事项,首先点胶量的大小通常认为胶点直径的大小应为产品间距的一半,这样就可以保证有充足的胶水来粘结组件又避免胶水过多。点胶量多少由时间长短来决定,实际中应根据温度和胶水的特性选择点胶时间。其次点胶压力方面,通常压力太大易造成胶水溢出、胶量过多;压力太小则会出现点胶断续现象和漏点,从而导致产品缺陷,所以需要根据环境温度和胶水粘度等因素进行调节。
Today, to say that the automatic dispensing machine liquid dispensing notes, first of all, the size of dispensing is usually thought that the size of the glue diameter should be half of the product spacing, so as to ensure that there is sufficient glue to glue components and avoid excessive glue. The amount of dispensing is determined by the length of time, in fact, according to the temperature and the characteristics of the glue should be selected dispensing time. Second, dispensing pressure, usually too much pressure easy to cause glue overflow, too much glue, pressure is too small will appear dispensing phenomenon and leakage point, resulting in product defects, so need to adjust according to the ambient temperature and glue viscosity and other factors.

再者,点胶机针头通常要选取针头内径大小为点胶胶点直径的1/2左右的针头,点胶过程中,应根据产品大小来选取点胶针头。还有针头与工作面之间的距离,不同的点胶机采用不同的针头,有些针头有一定的止动度,因此需要把握好点胶距离,甚至每次工作开始之前应做针头与工作面距离的校准,即Z轴高度校准。
In addition, dispensing machine needles usually to choose the needle inner diameter size of the dispensing point diameter of about 1/2 of the needle, dispensing process, should be based on the size of the product to choose the dispensing needle。 There is also the distance between the needle and the work surface, different dispensing machine using different needles, some needles have a certain degree of stopping, so it is necessary to grasp the dispensing distance, even before the start of each work should do the needle and the work surface distance calibration, that is, Z-axis height calibration。

除却点胶机本身的因素,胶水的粘度直接影响点胶的质量,粘度大,则胶点会变小,甚至拉丝;粘度小,胶点会变大,进而可能渗染产品,而胶水温度应为23℃~25℃;环境温度对胶水的粘度影响,温度降低粘度增大,出胶流量相应变小,更容易出现拉丝现象。胶水固化温度曲线生产厂家已给出,在实际应尽可能采用较高温度来固化,使胶水固化后有足够强度。
In addition to the factors of dispensing machine itself, the viscosity of the glue directly affects the quality of dispensing, the viscosity is larger, then the glue point will become smaller, or even wire, the viscosity is small, the glue point will become larger, and then the glue temperature should be 23 degrees C to 25 degrees C; It is more prone to fission. Glue curing temperature curve manufacturer has given, in practice should be as high as possible to use a higher temperature to cure, so that the glue cure after sufficient strength.
