不同的胶质的胶水对点胶机有何影响

自动点胶机设备本身是控制胶水吐出量和吐出时间的装置,对点胶机胶水要求方面,胶水一定不能有气泡,一个小小气即会造成许多焊盘没有胶水,造成空打现象,导致产生不合格的产品,所以每次中途更换胶管时必须排空连接处,对于胶水的固化,一般生产厂家已给出温度曲线,在实际应尽可能采用较高温度来固化,使胶水固化后有足够强度。
Automatic dispensing machine equipment itself is to control the amount of glue spit out and spit out the time of the device, the dispensing machine glue requirements, glue must not have bubbles, a small gas will cause many pads without glue, resulting in the phenomenon of empty punching, resulting in the production of unqualified products, so each midway to replace the hose must be emptied connection, for the curing of glue, General manufacturers have given the temperature curve, in practice should be as far as possible to use a higher temperature to solidify, so that the glue after curing has sufficient strength.

胶水的粘度直接影响点胶的质量,粘度大,则胶点会变小,甚至拉丝;粘度小,胶点会变大,进而可能渗染焊盘。点胶过程中,应对不同粘度的胶水,选取合理的背压和点胶速度。所以自动点胶机设备应根据不同同品质的胶水、点胶机工作环境温度等情况来来选择压力。环境温度高则会使胶水粘度变小、流动性变好,这时需调低背压即可保证胶水的供给,反之亦然。
The viscosity of the glue directly affects the quality of the dispensing, the viscosity is large, then the glue point will become smaller, or even brushed, the viscosity is small, the glue point will become larger, and then may seep the pad. In the process of dispensing, the glue with different viscosity should be selected, and reasonable back pressure and dispensing speed should be chosen. Therefore, automatic dispensing machine equipment should be based on different quality of glue, dispensing machine operating environment temperature and other conditions to choose the pressure. High ambient temperature will make the glue viscosity smaller, better fluidity, then need to lower the back pressure to ensure the supply of glue, and vice versa.

自动点胶机设备点胶量的大小根据工作经验,胶点直径的大小应为焊盘间距的一半,贴片后胶点直径应为胶点直径的1。5倍,这样即可以保证有充足的胶水来粘结元件又避免过多胶水浸染焊盘,点胶量多少由螺旋泵的旋转时间长短来决定,实际中应根据室温、胶水的粘性等选择泵的旋转时间。总之,使用自动点胶机可大大提高生产效率和减小产品的报废,节省胶水,便可达到产品量化和提高经济效率的目的。
The size of the dispensing device of automatic dispensing machine according to the working experience, the diameter of the rubber point should be half the spacing of the pad, After the patch, the diameter of the adhesive point should be 1。5 times times the diameter of the glue point, so that you can ensure that there is sufficient glue to bond the element and avoid too much glue dipping pad, the amount of dispensing is determined by the length of the spiral pump rotation time, in practice should be based on room temperature, glue viscosity and other choice of pump rotation time。 In short, the use of automatic dispensing machine can greatly improve production efficiency and reduce product scrapping, save glue, you can achieve product quantification and improve economic efficiency purposes。
