PU打膠機效率高的關鍵是什么？
PU打膠機的壓力直接影響到供膠量和出膠速度。膠水的流動性越差，它就會越厚，它需要的壓力就越大。因此，在生產(chǎn)過程中應根據(jù)自動配膠機的環(huán)境溫度、配膠量的大小和膠水的特性來調(diào)節(jié)壓力。配藥機的壓力由其內(nèi)部壓力調(diào)節(jié)閥調(diào)節(jié)。
The pressure of PU glue beater directly affects the quantity of glue supplied and the speed of glue discharged. The less liquid the glue is, the thicker it will be and the more pressure it will need. Therefore, in the production process, the pressure should be adjusted according to the environmental temperature of the automatic glue mixer, the size of the glue volume and the characteristics of the glue. The pressure of dispensing machine is regulated by its internal pressure regulating valve.
對于膠水的固化，一般廠家給出了溫度曲線。一般來說，它可以在室溫下固化。在實際操作中，應盡量采用較高的溫度，使膠水固化后具有足夠的強度和硬度。
For the curing of glue, the temperature curve is given by the general manufacturer. Generally speaking, it can be cured at room temperature. In practice, higher temperature should be used as far as possible to make the glue have enough strength and hardness after curing.
在全自動點膠機的配膠過程中，氣泡會影響到產(chǎn)品的質(zhì)量，所以在上膠前一定不能有氣泡。如果有氣泡，配藥機生產(chǎn)的產(chǎn)品會有很多次品。為防止配膠機打氣，在使用過程中應排膠。
Bubbles will affect the quality of products in the process of dispensing with automatic dispensing machine, so there must be no bubbles before gluing. If there are bubbles, the products produced by dispensing machine will have many defective products. In order to prevent the mixer from blowing up, the glue should be discharged during the use.
點膠機必須安裝真空回吸閥，因為真空回吸功能是防止點膠機的膠水在點膠時滴落。若安裝此機組，可合理調(diào)整真空回吸閥，進一步控制滴水和拉絲。
Vacuum backdraft valve must be installed in dispensing machine, because the function of vacuum backdraft is to prevent the glue of dispensing machine from dropping during dispensing. If the unit is installed, the vacuum backdraft valve can be adjusted reasonably to further control dripping and wire drawing.
針的規(guī)格會影響配藥機在配藥過程中的尺寸和精度。當壓力在一定范圍內(nèi)時，針尖越大，配藥速度越大。因此，配藥針的大小應根據(jù)配藥機生產(chǎn)的產(chǎn)品的大小來確定。一般來說，針的內(nèi)徑長度應保持在配點直徑的一半左右，效果好。
The size and accuracy of dispensing machine will be affected by the needle specifications. When the pressure is within a certain range, the greater the needle tip, the faster the dispensing speed. Therefore, the size of dispensing needle should be determined according to the size of products produced by dispensing machine. Generally speaking, the inner diameter length of the needle should be kept at about half of the diameter of the collocation point, and the effect is good.
自動點膠機的針距PCB板的距離不同，不同的點膠機使用不同的針，有的針有一定的硬度。每項工作開始時都要校準針距PCB的距離，即Z軸高度校準。
The needle distance of automatic dispensing machine is different from PCB board. Different dispensing machines use different needles, some needles have certain hardness. At the beginning of each work, the distance between the needle and PCB, i.e. Z-axis height calibration, should be calibrated.
配膠量由配膠機在配膠過程中的持續(xù)時間決定。根據(jù)我們的經(jīng)驗，配藥時間越長，配藥量越大。這樣可以保證雙組份灌膠機有足夠的膠水粘接元件，避免膠水過多造成資源浪費。
The amount of rubber is determined by the duration of the rubber mixer in the process of rubber mixing. According to our experience, the longer the dispensing time is, the larger the dosage is. This can ensure that the two-component glue filling machine has enough glue bonding components to avoid waste of resources caused by excessive glue.
