在點膠機運行過程中經常出現哪些缺陷?

  雙組份打膠機如果不及時處理,它將簡單地引起生產質量問題,甚至影響電氣功能,包括繪圖,涂抹,不連續的膠點,無膠點和附件膠點。
  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.
   我們知道,拉線和膠水的尾巴是點膠過程中的常見現象。 即使是專門用于高速環氧膠的膠也可能會出現拉絲現象,并且膠更容易掉落并可能產生幻覺。 焊接。 這可能是因為未調整分配器設備的工藝參數,例如針頭的內徑太小,分配壓力太高以及針頭和PCB之間的距離太大。
  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.


   由于另一個原因,膠水的功能可能無法理解。 修補膠與施工過程不兼容。 貼劑的質量可能不佳,粘度可能已更改或已過期。 其他原因也可能導致拉伸/拖尾,例如對板的靜電放電,板的彎曲或板的支撐。
   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,可以調節工藝參數,可以更換較大內徑的針頭,可以降低分配壓力,并且可以調節針頭與PCB的高度。 檢查一起使用的貼劑的生產日期,膠水的功能和應用要求,是否適合該工藝? 涂層等。如果補丁確實發生了變化,可以將其更換。 另外,已經證明控制拉伸/尾部的良好方法是將其加熱在分配針上或附近,降低粘度,并且貼劑容易破裂,并且不會發生拉伸/尾部。 自動分配器似乎是一種非常簡單的機械裝置。 但是,您還必須使用一定數量的技術內容才能使用它。 特別是在安裝的情況下,如果在安裝過程中出現錯誤,很容易引起熔爐的故障和不利影響。 因此,在購買自動分配器時,我們需要請人員進行安裝工作。 這里我們將重點介紹雙組份打膠機安裝時要注意的地方:
  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,首先是安全問題,安裝前必須先安裝地線,當自動點膠機工作時,會有很高的電壓。 為了防止發生事故,必須先安裝地線。 頻繁使用自動分配器時,很長一段時間都將其遺忘。 如果安裝了接地線,將大大改善安全措施。
  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,電壓穩定。 眾所周知,一般機械設備的工作電壓是220V,有些是380V,這些都是需要注意的,電壓的不穩定性很可能對我們的機械設備造成嚴重損害。 減少機器壽命。
  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.
