自动点胶机常见的两种滴胶泵工作原理及特点

阿基米德式滴胶泵工作原理:压缩空气送入胶瓶(注射器),将胶压进进给管中,胶流经以固定时间、特定速度旋转的螺杆。螺杆的旋转在胶剂上形成剪切力,使胶剂沿螺纹流下,螺杆的旋转在胶剂上不断加压,使其从滴胶针嘴流出。特点是具有胶点点径无固定限制的灵活性。可通过软件进行调整。但是滴大胶点时,螺杆旋转时间长,会降低整台机器的产量。另外,胶剂的粘度和流动特性会影响其稳定性。

Archimedes Type drip pump working principle: Compressed air into the rubber bottle (syringe), the glue into the feed tube, glue flowing through the fixed time, a certain speed of rotation of the screw. The rotation of the screw forms a shear force on the adhesive, so that the adhesive flow along the thread, the rotation of the screw on the adhesive constantly pressurized, so that it from the drip needle mouth outflow. It is characterized by flexibility with no fixed limit on the size of the dispensing point. It can be adjusted by software. However, when the large glue point, the screw rotation time is long, will reduce the output of the entire machine. In addition, the viscosity and flow characteristics of the adhesive will affect its stability.

无接触式滴胶泵工作原理:压缩空气送入胶瓶(注射器),将胶压进和活塞室相连的进给管中,在此加热,温度受控制,以达到最佳的始终如一的粘性。使用一个球座结构啊~啊~啊~啊~啊~爽~爽,胶剂填充由于球从座中缩回留下的空缺。当球回来时,由于加速产生的力量断开胶剂流,使其从滴胶针嘴喷射出,滴到板上形成胶点。特点是消除了传统方法产生的胶点拉尾。没有滴胶针的磨损和和其它零件干涉的问题。无针嘴损坏。无由于基板弯曲和被针嘴损害的报废。

Contactless drip pump working principle: Compressed air into the rubber bottle (syringe), the glue into the piston chamber connected to the feed tube, heated here, temperature controlled to achieve the best consistent viscosity. Using a ball seat structure, the glue is filled due to the gap left by the ball retracting from the seat. When the ball comes back, the acceleration produces the power to disconnect the glue flow, so that it ejected from the drip needle nozzle, dripping onto the plate to form a glue point. The characteristic is to eliminate the traditional method to produce the glue point pull tail. There is no problem with the wear of the glue needle and the interference with other parts. No needle nozzle damage. No scrap due to substrate bending and damage to the needle nozzle.
