影响点胶机点胶效果的因素通常有点胶量的大小,点胶压力,针头大小 ,针头与工作面之间的距离,胶水的粘度,胶水温度,固化温度曲线,胶水中气泡,需要特殊设定的流体等,下面点自动胶机厂家来为大家详细解读一下其中的原因。
The factors affecting the dispensing effect of the dispenser are usually a bit of the size of the glue, dispensing pressure, needle size, the distance between the needle and the working face, glue viscosity, glue temperature, curing temperature curve, the bubble in the glue, the need for special settings of the fluid, the following point automatic glue machine manufacturers to explain in detail the reasons.

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。
First of all, the size of the dispensing volume is generally believed that the size of the glue point diameter should be half the product spacing, so as to ensure that there is sufficient glue to bond the components and avoid too much glue. The amount of dispensing is determined by the length of time, the actual temperature and glue should be based on the characteristics of the selection of dispensing time. The next point of pressure, usually too much pressure to cause glue overflow, too much glue, too small pressure will appear intermittent phenomenon and leakage point, resulting in product defects, so the need to be based on environmental temperature and glue viscosity and other factors to adjust.

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,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。
Dispensing machine needles are usually selected needle diameter of 1/2 points in the diameter of the needle, dispensing process, should be based on the product size to select the dispensing needle, needle and the distance between the working face, different dispensing machine using different needles, some needles have a certain degree of stop, so need to grasp the distance of the glue.the calibration of the needle to the working face distance, i.e. the z-axis height calibration, should be done even before the start of each work.

除了点胶机本身的因素,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。做好以上三点基本上可以防止点胶机在使用过程中出现点胶异常的问题。
In addition to the dispenser itself, the viscosity of the glue directly affects the quality of the dispensing, viscosity is large, the glue point will become smaller, or even drawing; the viscosity is small, the glue point will become larger, and then may be infiltrated products, and the glue temperature should be 23℃~25℃; the influence of ambient temperature on the viscosity of glue, temperature decrease viscosity increase, More prone to wire drawing phenomenon. Glue curing temperature curve manufacturers have given, in practice should be used as high as possible temperature to cure, so that the glue after curing has enough strength. Do the above three points can basically prevent the dispensing machine in the use of the process of dispensing abnormal problems.
