電子產(chǎn)品一直是全自動(dòng)點(diǎn)膠機(jī)商家的主要輸出范圍，全自動(dòng)點(diǎn)膠機(jī)商家想要搶占電子產(chǎn)品的市場(chǎng)，應(yīng)牢記的就是根據(jù)當(dāng)下需求來(lái)進(jìn)行生產(chǎn)經(jīng)營(yíng)。
Electronic products have always been the main output range of automatic dispensers. In order to seize the market of electronic products, automatic dispensers should bear in mind that production and operation should be carried out according to the current demand.
影響點(diǎn)膠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，下面阿萊思斯技術(shù)人員就來(lái)為大家做一個(gè)簡(jiǎn)單的介紹，希望可以有所協(xié)助。
The factors that affect the dispensing effect usually include the size of dispensing amount, dispensing pressure, needle size, spacing between the needle and the working face, glue viscosity, glue temperature, curing temperature curve, bubbles in glue, fluid required for special settings, etc. the following is a brief introduction by aless technicians, hoping to help you.
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(lái)粘結(jié)組件又防止膠水過(guò)多。點(diǎn)膠量幾由時(shí)間長(zhǎng)短來(lái)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(shí)間。
First of all, the size of the dispensing amount usually assumes that the size of the glue dot diameter should be half of the product spacing, so as to ensure that there is enough glue to bond the components and prevent excessive glue. In practice, the dispensing time should be selected according to the temperature and the characteristics of the glue.
其次點(diǎn)膠壓力方面，通常壓力太大易形成膠水溢出、膠量過(guò)多；壓力太小則會(huì)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)理自動(dòng)點(diǎn)膠機(jī)。
Secondly, in terms of dispensing pressure, too much glue is easy to form when the pressure is too high; if the pressure is too small, it will lead to intermittent dispensing and leakage, which will lead to product defects. Therefore, it is necessary to stop conditioning the automatic dispenser according to the environmental temperature and glue viscosity.
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(guò)程中，應(yīng)依據(jù)產(chǎn)品大小來(lái)選取點(diǎn)膠針頭。
In addition, the pinhead of dispensing machine usually needs to select the needle whose inner diameter is about 1 / 2 of the dispensing point diameter. During dispensing, the dispensing needle should be selected according to the product size.
還有，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(dòng)度，因而需求把握好點(diǎn)膠間隔，以至每次工作開(kāi)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)。
In addition, the distance between the needle and the working face is different. Different dispensers use different needles, and some needles have a certain degree of stop. Therefore, it is necessary to grasp the dispensing interval and calibrate the spacing between the needle and the working face before the beginning of each work, i.e. z-axis height calibration.
除卻全自動(dòng)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(huì)變小，以至拉絲；粘度小，膠點(diǎn)會(huì)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(duì)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。膠水固化溫度曲線消費(fèi)廠家已給出，在實(shí)踐應(yīng)盡可能采用較高溫度來(lái)固化，使膠水固化后有足夠強(qiáng)度。
In addition to the elements of the automatic dispenser itself, the viscosity of the glue directly affects the quality of the dispensing. If the viscosity is high, the glue point will become smaller and even wire drawing will occur; if the viscosity is small, the glue point will become larger, and then the product may be dyed, and the glue temperature should be 23 ℃ - 25 ℃; the environmental temperature will affect the viscosity of the glue, the temperature will decrease, the viscosity will increase, and the glue flow will be reduced accordingly, which will make the drawing phenomenon easier 。 The curing temperature curve of glue has been given by the consumer. In practice, it should be cured at a higher temperature as much as possible, so that the glue has enough strength after curing.
另外膠水一定不能有氣泡。一個(gè)小小氣泡就會(huì)形成許多產(chǎn)品沒(méi)有膠水；每次中途改換膠管時(shí)應(yīng)排空銜接處的空氣，避免呈現(xiàn)空打現(xiàn)象。
In addition, the glue must not have bubbles. A small bubble will form a lot of products without glue. When changing the rubber tube midway, the air at the joint should be emptied to avoid empty hitting.
電子產(chǎn)品越來(lái)越重視用戶體驗(yàn)，輕薄化就是其中一個(gè)主要的發(fā)展趨向。招致電子元件越來(lái)越小，元件的大小在1mm左右曾經(jīng)很常見(jiàn)。在電路板上的元件之間的間隔也越來(lái)越近。傳統(tǒng)點(diǎn)膠機(jī)用肉眼人工示教編程的方式曾經(jīng)無(wú)法精確定位了，應(yīng)用CCD成像技術(shù)，將產(chǎn)品放大30-50倍顯現(xiàn)在電腦屏幕上，停止精確定位編程才干滿足客戶的消費(fèi)請(qǐng)求。
Electronic products pay more and more attention to user experience, and lightness is one of the main development trends. As a result, electronic components are becoming smaller and smaller, and the size of the components is about 1 mm. The spacing between the components on the circuit board is getting closer and closer. Traditional dispensing machine with naked eye manual teaching programming method has been unable to accurately locate, the application of CCD imaging technology, the product magnified 30-50 times displayed on the computer screen, stop accurate positioning programming ability to meet customer demand.
應(yīng)用不同像素的CCD和鏡頭不同放大倍數(shù)，以及多種光源的組合，能夠完成十分準(zhǔn)確的定位精度，同時(shí)能夠經(jīng)過(guò)編程順應(yīng)產(chǎn)品本身的個(gè)體誤差。
The application of CCD with different pixels and different magnification of lens, as well as the combination of various light sources, can achieve very accurate positioning accuracy, at the same time, it can be programmed to adapt to the individual error of the product itself.
響點(diǎn)膠精度的因素很多，自然不止上面所舉的一些，有的時(shí)候甚至是各種力量共同作用的結(jié)果。這就對(duì)點(diǎn)膠工藝提出了更高的要求，一方面應(yīng)當(dāng)盡量避免問(wèn)題的出現(xiàn)，另一方面，問(wèn)題已經(jīng)出現(xiàn)的時(shí)候需要根據(jù)實(shí)際生產(chǎn)操作流程找到原因，解決問(wèn)題。
There are many factors affecting the accuracy of dispensing. Naturally, it is not only some of the above mentioned, but sometimes even the result of the joint action of various forces. This puts forward higher requirements for dispensing process. On the one hand, problems should be avoided as far as possible. On the other hand, when problems have appeared, the causes should be found and solved according to the actual production process.
