如何自動(dòng)灌膠機的拉絲問(wèn)題?由于工藝要求高，有些產(chǎn)品需要使用高粘度的膠水。由于高粘度的特點(diǎn)，點(diǎn)膠過(guò)程中會(huì )出現拉絲現象，不僅影響質(zhì)量，還會(huì )影響外觀(guān)。面對膠圖，大家應該學(xué)習以下技巧。
How to solve the drawing problem of automatic glue filling machine? Due to the high technological requirements, some products need to use high viscosity glue. Due to the characteristics of high viscosity, there will be wire drawing phenomenon in the dispensing process, which not only affects the quality, but also affects the appearance. In the face of glue map, you should learn the following skills.
1.膠口延遲
1. Glue mouth delay
打開(kāi)膠頭時(shí)，由于膠頭出水口與膠閥之間有一定距離，所以膠頭之間沒(méi)有膠水。如果把膠頭出水口打開(kāi)，立即開(kāi)始運動(dòng)，會(huì )導致賽道開(kāi)始時(shí)短時(shí)間缺膠。為防止這種情況發(fā)生，在開(kāi)膠后，延遲一段時(shí)間，等膠水流出后，再進(jìn)行后續動(dòng)作。這種延遲時(shí)間稱(chēng)為開(kāi)膠延遲。
When opening the glue head, there is no glue between the glue heads because there is a certain distance between the water outlet of the glue head and the glue valve. If the water outlet of the rubber head is opened and the movement starts immediately, it will lead to short-term lack of rubber at the beginning of the track. In order to prevent this situation, after opening the glue, delay for a period of time, wait for the glue to flow out, and then carry out the follow-up action. This delay time is called glue opening delay.
2.膠關(guān)閉延遲
2. Glue closing delay
關(guān)閉膠頭后，膠頭出膠口與膠閥之間仍有膠。關(guān)閉膠頭后立即移動(dòng)，可能形成膠尾現象。為了防止發(fā)生這種情況，在關(guān)閉膠頭后，延遲一段時(shí)間，等待膠水流出，然后進(jìn)行后續動(dòng)作。這種延遲時(shí)間稱(chēng)為膠合延遲。
After closing the rubber head, there is still glue between the rubber head outlet and the rubber valve. The rubber tail may be formed when the rubber head is moved immediately after closing. In order to prevent this situation, after closing the glue head, delay for a period of time, wait for the glue to flow out, and then carry out the follow-up action. This delay time is called gluing delay.
3.圖的高度
3. The height of the graph
由于有些膠水粘度高，只有在膠水以恒定的速度緩慢提升一定距離后才能將膠水拉出，不影響上膠軌道。這個(gè)距離稱(chēng)為繪圖高度。
Due to the high viscosity of some glue, the glue can be pulled out only after the glue is slowly raised for a certain distance at a constant speed, which does not affect the gluing track. This distance is called the drawing height.
4.舉升高度
4. Lifting height
配藥時(shí)跟蹤的一個(gè)部分是完成并且空白移動(dòng)到下一節的起點(diǎn),為了防止橡膠頭針,橡膠抬起頭部在終點(diǎn)一定高度,確保橡膠頭不針,然后把空白的起點(diǎn)的下一節軌道,這叫做舉升高度。
When dispensing, one part of the tracking is to complete and move the blank to the starting point of the next section. In order to prevent the rubber needle, the rubber raises its head at a certain height at the end point to ensure that the rubber head does not secure the needle. Then the next section of the track at the starting point of the blank is called the lifting height.
5.預封膠
5. Pre sealing glue
即提前收膠距離，是指在連續軌跡上涂膠過(guò)程中，在到達終點(diǎn)前關(guān)閉膠頭，避免在殘余壓力和殘余膠水完成后，在末端段堆積膠水。這個(gè)軌跡的長(cháng)度被稱(chēng)為“粘近距離”。
That is, the glue collection distance in advance refers to closing the glue head before reaching the end point in the process of gluing on the continuous track, so as to avoid accumulating glue at the end section after the completion of residual pressure and residual glue. The length of this trajectory is called "sticky proximity.".
6.結束動(dòng)作
6. End action
調劑后的整個(gè)教學(xué)跟蹤,用戶(hù)可以設置橡膠頭搬到指定的位置,或者處理文件的起始點(diǎn),或終點(diǎn)的處理文件,或重置,或連接文件,為了方便的選擇和放置工件,提高處理效率,或加工誤差。這個(gè)項目被稱(chēng)為關(guān)閉動(dòng)作。
For the whole teaching tracking after dispensing, the user can set the rubber head to move to the specified position, or process the starting point or end point of the file, or reset or connect the file, in order to facilitate the selection and placement of the workpiece, improve the processing efficiency, or eliminate the processing error. This project is called a close action.
7.電纜在提升
7. The cable is lifting
由于膠水的粘性，合膠后直接拉膠動(dòng)作不能達到斷膠絲的效果，或者拉出的膠絲形狀不符合要求。因此，關(guān)閉橡膠頭后，斜拉索向上吊起，為拉線(xiàn)做準備。
Due to the stickiness of the glue, the direct pulling action after gluing can not achieve the effect of breaking the glue wire, or the shape of the pulled glue wire does not meet the requirements. Therefore, after closing the rubber head, the stay cable is lifted up to prepare for the stay cable.
8.膠加熱
8. Glue heating
可以試著(zhù)將膠水加熱到合適的溫度，增加膠水的流動(dòng)性，從某種意義上拉絲的問(wèn)題!注意加熱溫度不宜過(guò)高。
You can try to heat the glue to a suitable temperature, increase the fluidity of the glue, and solve the problem of wire drawing in a sense! The heating temperature should not be too high.
