打膠機(jī)的操作了解五方面要點(diǎn)
使用
雙組份打膠機(jī)前，請(qǐng)務(wù)完全掌握打膠機(jī)的操作知識(shí)后再進(jìn)行設(shè)備操作。接通電源前，請(qǐng)檢查電源、電壓是否穩(wěn)定。接通機(jī)器電源后，應(yīng)注意打膠機(jī)有無(wú)異常聲音，如果有請(qǐng)立即關(guān)閉機(jī)器，排除問(wèn)題后再接通電源。為了更好地保證產(chǎn)品質(zhì)量，提高生產(chǎn)效率，那么，下面就來(lái)了解一下打膠機(jī)的操作知識(shí)要點(diǎn)。
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(jù)工作經(jīng)驗(yàn)，粘結(jié)點(diǎn)直徑的大小應(yīng)為墊間距的一半，粘貼后粘結(jié)點(diǎn)直徑應(yīng)為粘結(jié)點(diǎn)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(pán)的過(guò)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(jī)背壓過(guò)大會(huì)溢出膠，膠量過(guò)大壓力過(guò)小會(huì)造成膠斷、漏，引起缺陷。請(qǐng)根據(jù)相同質(zhì)量的粘接劑、工作環(huán)境溫度選擇壓力。環(huán)境溫度高的話粘接劑的粘度會(huì)變小，流動(dòng)性會(huì)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(shí)際中，針的內(nèi)徑大小須是點(diǎn)膠點(diǎn)直徑的1/2。打膠機(jī)點(diǎn)膠過(guò)程中，須根據(jù)PCB上墊片的大小選擇點(diǎn)膠針。例如，如果0805和1206的焊盤(pán)的大小不同，則可以選擇相同的針，但是對(duì)于相差很大的焊盤(pán)，須選擇不同的針。這樣，可以在確保點(diǎn)膠質(zhì)量的同時(shí)提高生產(chǎn)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(jī)與PCB板之間的距離。打膠機(jī)針尖因自動(dòng)分配器而異，有些針尖有一定的停止度。每次開(kāi)始作業(yè)時(shí)，應(yīng)進(jìn)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(jī)膠粘劑溫度。一般環(huán)氧樹(shù)脂膠粘劑應(yīng)保存在0--5的冰箱中，使用時(shí)提前1/2小時(shí)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(huán)境溫度對(duì)膠粘劑的粘度影響較大，溫度過(guò)低會(huì)導(dǎo)致粘結(jié)點(diǎn)變小，出現(xiàn)拉絲現(xiàn)象。環(huán)境溫度相差5時(shí)，50%的膠量發(fā)生變化。因此，有要控制環(huán)境溫度。另外，還應(yīng)保證環(huán)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.
