灌膠機(jī)膠水拉絲的原因有哪些？
1、開膠延遲
1. Opening delay
在翻開膠頭時(shí)，由于膠頭出膠口與膠閥之間有段間隔，這段之間沒有膠水，假如翻開膠頭輸出口后，立刻開端運(yùn)動(dòng)，會(huì)招致軌跡開端一小段缺膠。為避免這種狀況，在開膠后，延遲一段時(shí)間，等候膠水流出，再執(zhí)行后續(xù)的運(yùn)動(dòng)。這段延遲時(shí)間稱為開膠延遲。
When opening the rubber head, there is no glue between the rubber head outlet and the rubber valve because of the interval between the rubber head outlet and the rubber valve. If the rubber head outlet is opened, it will start to move immediately, which will cause a small gap at the beginning of the trajectory. To avoid 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 movement. This delay time is called the opening delay.
2、關(guān)膠延遲
2. Delay of glue shutdown
在關(guān)閉膠頭后，膠頭出膠口與膠閥之間還有膠水未流完，假如在關(guān)閉膠頭后立刻運(yùn)動(dòng)，可能構(gòu)成膠水拖尾現(xiàn)象。為避免發(fā)作，在關(guān)閉膠頭后，延遲一段時(shí)間等候膠水流完，再執(zhí)行后續(xù)動(dòng)作。這段延遲時(shí)間稱為關(guān)膠延遲。
After closing the rubber head, there is still unfinished glue between the rubber head outlet and the rubber valve. If the rubber head moves immediately after closing, it may constitute the phenomenon of glue tailing. In order to avoid seizures, after closing the rubber head, delay for a period of time until the glue water is finished, and then perform the follow-up action. This delay time is called shutdown delay.
3、拉絲高度
3. Drawing Height
由于某些膠水的黏度較大，在勻速遲緩上抬一段間隔才干將膠絲拉斷，不影響涂膠軌跡，這段間隔稱為拉絲高度。
Because of the high viscosity of some glue, it is only by raising a interval at a constant speed and slowly that the glue can be broken without affecting the glue trajectory. This interval is called the drawing height.
4、上抬高度
4. Uplift Height
當(dāng)一段軌跡點(diǎn)膠完畢后，空移下一段軌跡的起點(diǎn)時(shí)，為了避免膠頭撞針，在完畢點(diǎn)將膠頭上抬一段高度保證膠頭平安不撞針，再空移下一段軌跡的起始點(diǎn)，這段高度稱為上抬高度。
When a trajectory has been glued and empty moved to the starting point of the next trajectory, in order to avoid collision of the glue head with the needle, the glue head is raised to a height at the end to ensure that the glue head does not collide with the needle safely, and then moved to the starting point of the next trajectory empty. This height is called lifting height.
5、提早關(guān)膠
5. Turn off glue early
即提早關(guān)膠間隔，是指在連續(xù)軌跡涂膠中，在抵達(dá)終點(diǎn)之前先關(guān)閉膠頭，以余壓和余膠走完后一段軌跡，防止完畢段堆膠。這段軌跡的長(zhǎng)度即“關(guān)膠間隔”。
That is to say, early shut-off interval refers to closing the rubber head before reaching the end point in continuous trajectory gluing, so as to prevent the glue stacking after the trajectory is finished with residual pressure and residual glue. The length of this trajectory is the "glue closing interval".
6、完畢動(dòng)作
6. Finish Action
在整個(gè)示教軌跡點(diǎn)膠完畢后，為了便當(dāng)取放工件、進(jìn)步加工效率或者消弭加工誤差，用戶能夠設(shè)定膠頭挪動(dòng)規(guī)范位置，或加工文件起點(diǎn)，或加工檔完畢點(diǎn)，或復(fù)位，或停止檔銜接。這個(gè)工程稱為完畢動(dòng)作。
After gluing the whole teaching trajectory, in order to take and place the workpiece conveniently, improve the processing efficiency or eliminate the processing error, the user can set the glue head to move to the standard position, or the starting point of the processing document, or the finishing point of the processing file, or reset, or stop the connection of the files. This project is called completion action.
7、斜拉上抬
7. Cable-Stayed Uplift
由于膠水黏度，在關(guān)膠后直接停止拉絲動(dòng)作不能到達(dá)拉斷膠絲效果，或者拉出的膠絲外形不契合請(qǐng)求。因而在關(guān)閉膠頭后，執(zhí)行斜拉上抬動(dòng)作為拉絲做準(zhǔn)備
Because of the glue viscosity, the effect of breaking the filament can not be achieved by stopping drawing directly after closing the glue, or the shape of the pulled filament does not meet the requirements. Therefore, after closing the rubber head, perform the pull-up action to prepare for wire drawing.
8、膠水加熱
8. Glue heating
能夠試著將膠水加熱到一個(gè)合適的溫度，增加的膠水的活動(dòng)性，也可從某種意義上處理拉絲!留意加熱的溫度不可過(guò)高!
Can try to heat glue to a suitable temperature, increase the activity of glue, can also handle wire drawing in a sense! Note that the heating temperature should not be too high!
