使用雙組份打膠機前，請務完全掌握打膠機的操作知識后再進行設備操作。接通電源前，請檢查電源、電壓是否穩定。接通機器電源后，應注意打膠機有無異常聲音，如果有請立即關閉機器，排除問題后再接通電源。為了更好地保證產品質量，提高生產效率，那么，下面就來了解一下打膠機的操作知識要點。

Before using the two-component sealant dispenser, be sure to fully master the operating knowledge of the sealant dispenser before operating the equipment. Before turning on the power, please check whether the power supply and voltage are stable. After the machine is powered on, pay attention to whether there is any abnormal sound in the glue applicator. If there is any abnormal sound, turn off the machine immediately, and then turn on the power after troubleshooting. In order to better ensure the product quality and improve the production efficiency, let's learn about the key points of operation knowledge of the glue dispenser.

一、根據工作經驗，粘結點直徑的大小應為墊間距的一半，粘貼后粘結點直徑應為粘結點直徑的1.5倍。因此，確保了能夠粘接部件的粘接劑，可以避免粘接劑向焊盤的過度浸染。

1、 According to work experience, the diameter of the bonding point shall be half of the pad spacing, and the diameter of the bonding point after pasting shall be 1.5 times of the diameter of the bonding point. Therefore, the adhesive that can bond components is ensured to avoid excessive impregnation of the adhesive to the pad.

二、打膠機背壓過大會溢出膠，膠量過大壓力過小會造成膠斷、漏，引起缺陷。請根據相同質量的粘接劑、工作環境溫度選擇壓力。環境溫度高的話粘接劑的粘度會變小，流動性會變好。這種情況下，需要降低背壓可以保證粘接劑的供給，反之亦然。

2、 Excessive back pressure of the glue applicator will overflow glue, and excessive glue amount and low pressure will cause glue break and leakage, resulting in defects. Please select the pressure according to the adhesive of the same quality and the working environment temperature. If the ambient temperature is high, the viscosity of the adhesive will become smaller and the fluidity will become better. In this case, it is necessary to reduce the back pressure to ensure the supply of adhesive, and vice versa.

三.在工作實際中，針的內徑大小須是點膠點直徑的1/2。打膠機點膠過程中，須根據PCB上墊片的大小選擇點膠針。例如，如果0805和1206的焊盤的大小不同，則可以選擇相同的針，但是對于相差很大的焊盤，須選擇不同的針。這樣，可以在確保點膠質量的同時提高生產效率。

III In practice, the inner diameter of the needle must be 1/2 of the diameter of the dispensing point. During dispensing, the dispensing needle must be selected according to the size of the gasket on the PCB. For example, if the sizes of pads of 0805 and 1206 are different, you can select the same pin, but for pads with large differences, you must select different pins. In this way, the production efficiency can be improved while ensuring the dispensing quality.

四.打膠機與PCB板之間的距離。打膠機針尖因自動分配器而異，有些針尖有一定的停止度。每次開始作業時，應進行針尖與PCB的距離校正，即z軸高度的校正。

IV The distance between the glue applicator and PCB board. The tip of the glue applicator varies with the automatic distributor, and some tips have a certain degree of stop. At the beginning of each operation, the distance between the needle tip and PCB should be corrected, that is, the z-axis height should be corrected.

五.打膠機膠粘劑溫度。一般環氧樹脂膠粘劑應保存在0--5的冰箱中，使用時提前1/2小時取出，確保膠粘劑充分符合使用溫度。粘接劑使用溫度為23--25;環境溫度對膠粘劑的粘度影響較大，溫度過低會導致粘結點變小，出現拉絲現象。環境溫度相差5時，50%的膠量發生變化。因此，有要控制環境溫度。另外，還應保證環境的溫度，濕度小的膠容易干，影響粘接力。

V Glue temperature of glue applicator. Generally, the epoxy resin adhesive shall be stored in a 0-5 refrigerator and taken out 1/2 hour in advance to ensure that the adhesive fully meets the use temperature. The use temperature of adhesive is 23-25; The ambient temperature has a great influence on the viscosity of the adhesive. If the temperature is too low, the bonding point will become smaller and wire drawing will occur. When the ambient temperature difference is 5, 50% of the glue content changes. Therefore, it is necessary to control the ambient temperature. In addition, the temperature of the environment should also be guaranteed. The glue with low humidity is easy to dry, which affects the adhesion.
