打胶机的操作了解五方面要点
使用
双组份打胶机前,请务完全掌握打胶机的操作知识后再进行设备操作。接通电源前,请检查电源、电压是否稳定。接通机器电源后,应注意打胶机有无异常声音,如果有请立即关闭机器,排除问题后再接通电源。为了更好地保证产品质量,提高生产效率,那么,下面就来了解一下打胶机的操作知识要点。
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、根据工作经验,粘结点直径的大小应为垫间距的一半,粘贴后粘结点直径应为粘结点直径的1.5倍。因此,确保了能够粘接部件的粘接剂,可以避免粘接剂向焊盘的过度浸染。
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、打胶机背压过大会溢出胶,胶量过大压力过小会造成胶断、漏,引起缺陷。请根据相同质量的粘接剂、工作环境温度选择压力。环境温度高的话粘接剂的粘度会变小,流动性会变好。这种情况下,需要降低背压可以保证粘接剂的供给,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.在工作实际中,针的内径大小须是点胶点直径的1/2。打胶机点胶过程中,须根据PCB上垫片的大小选择点胶针。例如,如果0805和1206的焊盘的大小不同,则可以选择相同的针,但是对于相差很大的焊盘,须选择不同的针。这样,可以在确保点胶质量的同时提高生产效率。
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.打胶机与PCB板之间的距离。打胶机针尖因自动分配器而异,有些针尖有一定的停止度。每次开始作业时,应进行针尖与PCB的距离校正,即z轴高度的校正。
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.打胶机胶粘剂温度。一般环氧树脂胶粘剂应保存在0--5的冰箱中,使用时提前1/2小时取出,确保胶粘剂充分符合使用温度。粘接剂使用温度为23--25;环境温度对胶粘剂的粘度影响较大,温度过低会导致粘结点变小,出现拉丝现象。环境温度相差5时,50%的胶量发生变化。因此,有要控制环境温度。另外,还应保证环境的温度,湿度小的胶容易干,影响粘接力。
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.
