點(diǎn)膠機(jī)運(yùn)行過程中常存在哪些缺陷？
如果不及時(shí)處理，將簡(jiǎn)單地形成生產(chǎn)質(zhì)量問題，甚影響電氣功能，包括拉拔，拖尾，不連續(xù)膠點(diǎn)，無膠點(diǎn)和附屬膠點(diǎn)等問題。
If not handled in time, it will simply result in quality problems in production and even affect electrical functions, including drawing, tailing, discontinuous adhesive, non-adhesive and affiliated adhesive.
我們知道，膠水的拉線和尾巴是點(diǎn)膠過程中的常見現(xiàn)象，即使是專門用于高速環(huán)氧膠的膠水也可能有拉絲現(xiàn)象，膠水更容易掉落，并可能造成假象。 焊接。 這可能是因?yàn)槲凑{(diào)整分配器設(shè)備的工藝參數(shù)，例如針頭的內(nèi)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 thread drawing and tail of glue are common phenomena in the dispensing process. Even the glue specially used for high-speed epoxy glue may also have wire drawing phenomena. The glue is easier to fall off and may cause false impressions. Welding. This may be due to the unadjusted process parameters of distributor equipment, such as too small inner diameter of the needle, too high distribution pressure and too large distance between the needle and PCB.
出于另一個(gè)原因，可能無法理解修補(bǔ)膠的功能。 修補(bǔ)膠與施工過程不兼容。 修補(bǔ)膠的質(zhì)量可能不好，粘度改變或已過期。 其他原因也可能引起拉伸/拖尾，例如對(duì)板的靜電放電，板的彎曲或板的支撐。
For another reason, the function of the patch may not be understood. The repair glue is incompatible with the construction process. The quality of the repairing glue may be poor, the viscosity may change or it has expired. Other causes may also cause stretching/tailing, such as electrostatic discharge to the plate, bending of the plate or support of the plate.
由于上述原因，可以調(diào)節(jié)工藝參數(shù)，可以更換較大內(nèi)徑的針頭，可以降低分配壓力，并且可以調(diào)節(jié)針頭從PCB上的高度。 一起檢查所用貼劑的生產(chǎn)日期，膠水的功能和應(yīng)用要求，是否適合該工藝？ 涂層等。如果貼劑確實(shí)發(fā)生了變化，則可以更換。 另外，已經(jīng)證明，控制拉伸/拖尾的一種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(huì)發(fā)生拉伸/拖尾。 自動(dòng)分配器似乎是一種非常簡(jiǎn)單的機(jī)械裝置。 但是，還必須使用一定數(shù)量的技術(shù)內(nèi)容才能使用它。 尤其是在安裝的情況下，如果在安裝過程中出現(xiàn)錯(cuò)誤，很容易引起熔化器的故障和不利影響，因此在購(gòu)買自動(dòng)分配器時(shí)，我們需要請(qǐng)人員進(jìn)行安裝工作。 這里我們將介紹安裝時(shí)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 from the PCB can be adjusted. Check the production date of the patch, the function and application requirements of the glue together. Is it 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 stretching/tailing is to heat it on or near the distributor needle, reduce the viscosity, and the patch is easy to crack, and no stretching/tailing occurs. The automatic distributor seems to be a very simple mechanical device. However, a certain amount of technical content must be used before it can be used. Especially in the case of installation, if there are errors in the installation process, it is easy to cause melter failure and adverse effects. Therefore, when purchasing automatic distributor, we need to ask professionals for installation work. Here we will focus on the installation of the points to be noted:
1，是問題，安裝時(shí)必須先安裝地線，當(dāng)自動(dòng)點(diǎn)膠機(jī)工作時(shí)，會(huì)有很高的電壓。 為了防止發(fā)生事故，必須安裝地線。 當(dāng)頻繁使用自動(dòng)分配器時(shí)，它會(huì)被遺忘很長(zhǎng)時(shí)間。 如果安裝了地線，將大大改善措施。
1. First of all, it is a safety problem. Ground wires must be installed before installation. When the automatic dispensing machine works, there will be a high voltage. In order to prevent accidents, ground wires must be installed first. When the automatic allocator is frequently used, it will be forgotten for a long time. If the ground wire is installed, the safety measures will be greatly improved.
2，電壓穩(wěn)定。 眾所周知，一般的機(jī)械設(shè)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(wěn)定性很可能對(duì)我們的機(jī)械設(shè)備造成嚴(yán)重?fù)p害。 減少機(jī)器壽命。
2. Voltage stability. As we all know, the working voltage of general mechanical equipment is 220V, and some are 380V. These are noteworthy. Voltage instability is likely to cause serious damage to our mechanical equipment. Reduce machine life.
