影響自動點(diǎn)膠機(jī)膠體粘度的原因
點(diǎn)膠壓力方面，通常壓力太大易形成膠水溢出、膠量過多;壓力太小則會呈現(xiàn)點(diǎn)膠斷續(xù)現(xiàn)象和漏點(diǎn)，從而招致產(chǎn)品缺陷，所以需求依據(jù)環(huán)境溫度和膠水粘度等要素停止調(diào)理。
As to the pressure of the glue, the pressure is too large to form the glue spillover and excess glue, and the pressure is too small to show the intermittent phenomenon and the leak point, thus causing the product defect, so the demand is stopped according to the environmental temperature and the viscosity of the glue.
影響自動點(diǎn)膠機(jī)點(diǎn)擊效果的要素通常有點(diǎn)膠量的大小，點(diǎn)膠壓力，針頭大小，針頭與工作面之間的間隔，膠水的粘度，膠水溫度，固化溫度曲線，膠水中氣泡，需求特殊設(shè)定的流體等等
The factors that affect the click effect of the automatic glue dispenser usually include the size of the amount of glue, the pressure of the glue, the size of the needle, the interval between the needle and the working face, the viscosity of the glue, the temperature of the glue, the curing temperature curve, the bubble in the glue, the need for the special set of fluid, and so on.
下面做下引見，希望可以有所協(xié)助點(diǎn)膠量的大小通常以為膠點(diǎn)直徑的大小應(yīng)為產(chǎn)品間距的一半，這樣就能夠保證有充足的膠水來粘結(jié)組件又防止膠水過多。點(diǎn)膠量幾由時間長短來決議，實(shí)踐中應(yīng)依據(jù)溫度和膠水的特性選擇點(diǎn)膠時間。
Under the following introduction, we hope that the size of the glue should be the size of the glue point in the first half of the product spacing, so that there is enough glue to ensure that the glue can be plentiful to prevent excessive glue. The amount of dispensing is decided by the length of time. In practice, the dispensing time should be chosen according to the characteristics of temperature and glue.
自動點(diǎn)膠機(jī)再者，點(diǎn)膠機(jī)針頭通常要選取針頭內(nèi)徑大小為點(diǎn)膠膠點(diǎn)直徑的1/2左右的針頭，點(diǎn)膠過程中，應(yīng)依據(jù)產(chǎn)品大小來選取點(diǎn)膠針頭。
In addition, the needles in the dispenser usually choose the needle with the diameter of the inner diameter of the needle, which is about 1/2 of the glue point diameter. In the process of dispensing, the pin should be selected according to the size of the product.
針頭與工作面之間的間隔，不同的點(diǎn)膠機(jī)采用不同的針頭，有些針頭有一定的止動度，因而需求把握好點(diǎn)膠間隔，以每次工作開端之前應(yīng)做針頭與工作面間隔的校準(zhǔn)，即Z軸高度校準(zhǔn)。
The interval between the needle and the working face, the different needles are different with different needles, some needles have a certain stop motion, so the need to grasp the glue interval, so that the calibration of the interval between the needle and the working face should be done before each work beginning, that is, the Z axis height calibration.
除卻點(diǎn)膠機(jī)自身的要素，膠水的粘度直接影響點(diǎn)膠的質(zhì)量，粘度大，則膠點(diǎn)會變小，以拉絲;粘度小，膠點(diǎn)會變大，進(jìn)而可能滲染產(chǎn)品，而膠水溫度應(yīng)為23℃～25℃;環(huán)境溫度對膠水的粘度影響，溫度降低粘度增大，出膠流量相應(yīng)變小，更容易呈現(xiàn)拉絲現(xiàn)象。
Apart from the elements of the glue dispenser itself, the viscosity of the glue directly affects the quality of the glue, and the viscosity is large and the glue point will become smaller and even drawing; the viscosity is small, the glue point will become larger, and then the adhesive will be dyed, and the glue temperature should be 23 to 25 C; the temperature of the environment affects the viscosity of the glue, the temperature reduces the viscosity and the flow phase of the glue. The strain is small and the drawing phenomenon is more easily presented.
