在点胶机运行过程中经常出现哪些缺陷?

发布时间:2019/10/30    发布人:

  双组份打胶机如果不及时处理,它将简单地引起生产质量问题,甚至影响电气功能,包括绘图,涂抹,不连续的胶点,无胶点和附件胶点。
  If the two-component dispenser is not handled in time, it will simply cause production quality problems and even affect electrical functions, including drawing, coating, discontinuous glue points, no glue points and accessory glue points.
   我们知道,拉线和胶水的尾巴是点胶过程中的常见现象。 即使是专门用于高速环氧胶的胶也可能会出现拉丝现象,并且胶更容易掉落并可能产生幻觉。 焊接。 这可能是因为未调整分配器设备的工艺参数,例如针头的内径太小,分配压力太高以及针头和PCB之间的距离太大。
  We know that the tail of cable and glue is a common phenomenon during dispensing. Even the glue specially used for high-speed epoxy glue may have wire drawing phenomenon, and the glue is easier to fall and may produce illusion. Welding. This may be due to unadjusted process parameters of distributor equipment, such as too small inner diameter of needle, too high distribution pressure and too large distance between needle and PCB.


   由于另一个原因,胶水的功能可能无法理解。 修补胶与施工过程不兼容。 贴剂的质量可能不佳,粘度可能已更改或已过期。 其他原因也可能导致拉伸/拖尾,例如对板的静电放电,板的弯曲或板的支撑。
   the function of glue may not be understood for another reason. The repair glue is not compatible with the construction process. The quality of the patch may be poor and the viscosity may have changed or expired. Other causes can also cause stretching / tailing, such as electrostatic discharge of the plate, bending of the plate, or support of the plate.
   由于上述原因,可以调节工艺参数,可以更换较大内径的针头,可以降低分配压力,并且可以调节针头与PCB的高度。 检查一起使用的贴剂的生产日期,胶水的功能和应用要求,是否适合该工艺? 涂层等。如果补丁确实发生了变化,可以将其更换。 另外,已经证明控制拉伸/尾部的良好方法是将其加热在分配针上或附近,降低粘度,并且贴剂容易破裂,并且不会发生拉伸/尾部。 自动分配器似乎是一种非常简单的机械装置。 但是,您还必须使用一定数量的技术内容才能使用它。 特别是在安装的情况下,如果在安装过程中出现错误,很容易引起熔炉的故障和不利影响。 因此,在购买自动分配器时,我们需要请人员进行安装工作。 这里我们将重点介绍双组份打胶机安装时要注意的地方:
  Because of the above reasons, the process parameters can be adjusted, the needle with larger inner diameter can be replaced, the distribution pressure can be reduced, and the height of the needle and PCB can be adjusted. Check whether the production date, glue function and application requirements of the pastes used together are suitable for the process. Coating and so on. If the patch does change, it can be replaced. In addition, it has been proved that a good way to control the stretch / tail is to heat it on or near the dispensing pin, reduce the viscosity, and the patch is easy to crack, and there is no stretch / tail. The automatic distributor seems to be a very simple mechanism. However, you must also use a certain amount of technical content to use it. Especially in the case of installation, if there are errors in the installation process, it is easy to cause furnace failure and adverse effects. Therefore, when purchasing the automatic distributor, we need to invite personnel to carry out the installation work. Here we will focus on the installation of the two-component dispenser:
   1,首先是安全问题,安装前必须先安装地线,当自动点胶机工作时,会有很高的电压。 为了防止发生事故,必须先安装地线。 频繁使用自动分配器时,很长一段时间都将其遗忘。 如果安装了接地线,将大大改善安全措施。
  1. First of all, it is a safety issue. Before installation, the ground wire must be installed first. When the automatic dispensing machine is working, there will be a high voltage. In order to prevent accidents, the ground wire must be installed first. When auto allocator is used frequently, it will be forgotten for a long time. If the grounding wire is installed, the safety measures will be greatly improved.
   2,电压稳定。 众所周知,一般机械设备的工作电压是220V,有些是380V,这些都是需要注意的,电压的不稳定性很可能对我们的机械设备造成严重损害。 减少机器寿命。
  2. The voltage is stable. As we all know, the working voltage of general mechanical equipment is 220V, and some is 380V, which needs attention. The instability of voltage is likely to cause serious damage to our mechanical equipment. Reduce machine life.
