雙液點膠機有哪些類型呢？
雙液點膠機有哪些類型呢？它們各自有什么優(yōu)缺點呢？下面為您做一下具體的介紹：
What are the types of double liquid dispenser? What are their advantages and disadvantages? Here is a detailed introduction for you:
一，簡易式雙液點膠機
1. Simple double-liquid dispensing machine
由兩個壓力桶和一個點膠控制器組成。將AB膠分別倒入到壓力桶中，通過氣壓將膠水壓出來，通過點膠控制器來調節(jié)氣壓的壓力和出膠時間，進而來控制出膠量。此類型雙液點膠機主要用于1：1的膠水。對于高于1：1的膠水，如4：1，5：1，10：1，10：3這樣的膠水則不適用。因為這種簡易的雙液點膠機兩邊壓力是一樣的，另外氣壓也是不穩(wěn)定的，有波動的，而比例相差較大的膠水，配比一定要精確，否則打出膠水是不干的。氣壓的波動會使膠水出來的忽多忽少，其比例就很難保證精確，一比一的膠水還好，無論A膠還是B膠哪一個多一點，或者少一點都會干，而多比例的膠水則非常嚴格，一定要精確。另外當前點膠控制器也有局限，從控制器給到兩個桶的壓力是一樣的，對于多比例的膠水，一邊的壓力要是另一邊壓力的倍數(shù)，但目前控制器做不到這一點。也許你會說增加一個儲氣罐，保持氣壓的穩(wěn)定，解決氣壓波動，但是控制器這一塊還是個瓶勁，還是沒法解決多比例的膠水。另外如果膠水比較稠，氣壓的壓力畢竟有限，就會出現(xiàn)打膠比較慢，效率不高，而一比一的膠水大部份都會比較粘稠，所以簡易式雙液點膠機目前主要以1：1膠水為主，也很便宜，主要適用于對效率要求不是很高的企業(yè)。簡易式雙液點膠機如下圖所示：簡易雙液點膠機
It consists of two pressure barrels and a dispensing controller. The AB glue is poured into the pressure barrel separately, and the glue is pressed out by the air pressure. The pressure of the air pressure and the time of glue release are regulated by the dispensing controller to control the glue output. This type of double-liquid dispenser is mainly used for 1:1 glue. For glue above 1:1, such as 4:1, 5:1, 10:1, 10:3 glue is not applicable. Because the pressure on both sides of this simple double-liquid dispenser is the same, and the pressure is also unstable and fluctuating, and the proportion of glue with large difference must be accurate, otherwise the glue is not dry. The fluctuation of air pressure will make the glue come out more or less, and its proportion is difficult to guarantee accuracy. One-to-one glue is better. No matter which one of A glue or B glue is more or less, it will dry, while the proportion of glue is very strict and must be accurate. In addition, the current dispensing controller also has limitations. The pressure from the controller to the two barrels is the same. For a large proportion of glue, the pressure on one side is a multiple of the pressure on the other side, but the current controller can not do this. Maybe you would say adding an air storage tank to keep the pressure stable and to solve the fluctuation of the pressure, but the controller is still a bottle power and still can't solve the problem of a large proportion of glue. In addition, if the glue is thicker and the pressure of air pressure is limited after all, there will be slow gluing and inefficient glue, and most of the glue will be thicker than one, so the simple double-liquid dispenser is mainly 1:1 glue at present, and the price is also cheap. It is mainly applicable to enterprises that do not require high efficiency. Simple double-liquid dispensing machine as shown in the following figure: Simple double-liquid dispensing machine
二，臺式雙液點膠機
2. Desktop double-liquid dispensing machine
臺式雙液點膠機的原理和簡易式雙液點膠機是一樣的，就增加了一個三軸機械手，實現(xiàn)自動點膠功能，將多個產品放在夾具上，一次性打完。而簡易式雙液點膠機每次只能打一個，這樣效率就提升了，但局限還是有的，只適用于一比一的膠水。臺式雙液點膠機如下圖所示：臺式雙液點膠機
The principle of desktop double-liquid dispensing machine is the same as that of simple double-liquid dispensing machine. A three-axis manipulator is added to realize the automatic dispensing function. Many products are put on the fixture and finished at one time. The simple double-liquid dispensing machine can only play one at a time, which improves the efficiency, but there are still some limitations, only for one-to-one glue. The table double-liquid dispensing machine is shown in the following figure: the table double-liquid dispensing machine
三，半自動雙液點膠機
3. Semi-automatic double-liquid dispensing machine
半自動雙液點膠機通過計量泵來計量，一個A泵，一個B泵。泵通過電機來驅動，電機帶動泵轉，每轉一圈其出膠體積是恒定的，不受氣壓控制，所以泵的出膠量是非常穩(wěn)定的，誤差是非常小的。泵轉的越快，其出膠也就越快，出膠量也就越大，對于多比例的膠水，在觸摸屏中調節(jié)泵的轉速就可以了。另外泵的壓力相對于氣壓來講，要大的多，所以出膠也會很快，點膠的效率較氣壓式的要快很多。計量泵的灌膠機從功能來講帶有自動清洗功能，維護很簡便，氣壓式的灌膠機沒有這個功能，點膠作業(yè)后，要手動的去拆下來清洗。計量泵點膠機料桶帶有液位感應功能，缺料會自動報警提示加膠；還帶有攪拌功能防止膠水沉淀，也可選配膠水抽真空功能，對膠水脫泡，減少點膠氣泡發(fā)生；也可以配置加熱功能，防止天氣變冷膠水變稠流不動。半自動雙液點膠機標配通過腳踏開關來控制出膠，針對比較小巧的產品，半自動雙液點膠機可外接手動槍閥，通過手按開關來控制出膠，讓操作更靈活。半自動雙液點膠機同氣壓式相比，功能比較強大，適用于多比例膠水，點膠效果更好，但方面要比氣壓式的貴很多。
Semi-automatic double-liquid dispensing machine is metered by metering pump, one A pump and one B pump. Pump is driven by motor, which drives the pump to rotate. The gel volume is constant in every turn and is not controlled by air pressure, so the gel volume of pump is very stable and the error is very small. The faster the pump rotates, the faster the glue is produced, and the larger the glue output. For a large proportion of glue, it is OK to adjust the speed of the pump in the touch screen. In addition, the pressure of the pump is much larger than that of the air pressure, so the glue will be produced quickly, and the dispensing efficiency is much faster than that of the air pressure type. The glue filling machine of metering pump has the function of automatic cleaning, which is easy to maintain. The pneumatic glue filling machine does not have this function. After dispensing, it should be removed and cleaned manually. The barrel of metering pump dispensing machine has the function of liquid level induction, which can automatically alarm and prompt glue feeding for material shortage; it also has the function of stirring to prevent glue precipitation; it can also choose the function of glue vacuum pumping to defoam glue and reduce the occurrence of dispensing bubbles; it can also be equipped with heating function to prevent the glue from becoming thick and immobile when the weather becomes cold. Semi-automatic double-liquid dispensing machine standard through the pedal switch to control the glue out, for smaller products, semi-automatic double-liquid dispensing machine can be connected with manual gun valve, through the manual switch to control the glue out, so that the operation is more flexible. The semi-automatic double-liquid dispensing machine is more powerful than the pneumatic dispensing machine. It is suitable for multi-proportion glue dispensing. The dispensing effect is better, but the price is much more expensive than the pneumatic dispensing machine.
四，三軸自動雙液點膠機
Fourth, three-axis automatic double-liquid dispensing machine
三軸自動雙液點膠機在原理上跟半自動雙液點膠機是一樣的，其不同點就是多了一個三軸機械手，實現(xiàn)產品批量點膠，減少人工拿放工序，效率要高一些。三軸自動雙液點膠機對產品的標準性要求較高，就是產品每個要一樣，不能變型，三軸機械手點膠是按照設定的軌跡來走，如果要點膠的孔位不一致，就有可能出現(xiàn)膠水點到外面來了。雙液自動點膠機需要治具來定位，而半自動點膠機則不需要。對于多樣化的產品，產品一致性比較差的產品，還有體積比較大的產品，半自動雙液點膠機則更適合。三軸雙液自動點膠機如下圖所示：自動雙液點膠機
The principle of three-axis automatic double-liquid dispensing machine is the same as that of semi-automatic double-liquid dispensing machine. The difference is that there is an additional three-axis manipulator to realize batch dispensing of products, reduce manual handling and release process, and the efficiency is higher. Three-axis automatic double-liquid dispensing machine requires higher standard of products, that is, each product should be the same, can not be modified, three-axis manipulator dispensing is in accordance with the set trajectory, if the hole position of the key glue is not consistent, it may appear glue point to the outside. Double-liquid automatic dispensing machine needs fixtures to locate, while semi-automatic dispensing machine does not. For a variety of products, products with poor consistency, and products with larger volume, semi-automatic double-liquid dispenser is more suitable. The three-axis double-liquid automatic dispensing machine is shown in the following figure: automatic double-liquid dispensing machine
五，雙液點膠機流水線
5. Dual-liquid dispenser assembly line
雙液點膠機流水線，由接驅臺，點膠機，真空機，固化爐，打標機，回轉線等組成，其優(yōu)點就是減少人工干擾，出來就是成品，產品品質的可靠性更高，效率更高，節(jié)省了大量人工，成本可以降低很多，但缺點就是前期投入比較大。雙液點膠機流水線如下圖所示：
Dual-liquid dispensing machine assembly line is composed of receiving and dispensing platform, dispensing machine, vacuum machine, curing furnace, marking machine, revolving line, etc. Its advantages are to reduce manual interference. It comes out as a finished product. The product has higher reliability, higher efficiency, saves a lot of labor and reduces costs, but the disadvantage is that the earlier investment is relatively large. The assembly line of the double-liquid dispenser is shown as follows:
綜上即為雙液點膠機的幾種類型介紹，每一種都有自己有優(yōu)勢，可以根據(jù)自己當前的實際情況來選取。適合自己的才是好的！
To sum up, it is the introduction of several types of double-liquid dispenser, each of which has its own advantages and can be selected according to its current actual situation. What suits you is the best!
