超聲波焊接原理

超聲波焊接強度分析及問題處理方法（二）

超声波焊接机的焊接强度直接影响産品的质量。继续带您了解不同的焊接强度条件和解決方案。上一篇文章讨论了焊接效果不一致的问题。在本文中，仍然从这个问题开始。
一、当産品出现焊接效果不一致的情况下，产生这种现象可能有以下几种原因：
1、脫模劑未清理。這時候我們可以用氟利昂TF清潔粘合表面。如果必須使用脫模劑，請使用可印刷或清漆型添加劑。

2、工作尺寸公差太大。可以選擇提高工件的尺寸精度；修改工件尺寸；檢查運行條件。

3、射出模與模間的變化。這時候要考慮到是否改善使用特定注塑模具的工件的焊接統計數據；注意檢查工件的公差和尺寸；檢查模具是否磨損；檢查運行條件。

4、焊機過程中使用輔助材料或低等級塑料。在這種情況下，首先請與工廠確認材料；其次要檢查運行條件；減少次要材料的比例。

5、電源電壓發生變化。電源電壓會直接影響到焊接效果，這時候可以選擇配置使用電源穩壓器。

6、氣壓下降。壓力的大小也直接關系到焊接效果，當氣壓不足下降時，選擇增加空氣源的輸出壓力；設備儲氣罐。

7、焊接线设计有误。焊线的设计也是直接影响到産品焊接后的美观牢固度的，设计正确的焊接线才能更好的利用超声波塑焊机焊接産品。

8、材料質量差。檢查操作條件。

9、工件貼合度不佳。檢查工件尺寸；檢查工件公差；檢查運行條件。

10、使用融合不良的材料。參閱塑料兼容性表，因爲不同材料間的融合效果不一樣，用超聲波焊接出來的效果也就不一樣。

11、（尼龙工件）模具是湿的。産品的湿度也是直接影响到焊接效果的，所以在焊接前要干燥模具；焊接后立即焊接工件。

以上是超聲焊接強度分析和問題解決方法的第二部分。

超聲波焊接強度分析及問題處理方法（一）

‘Oh, yes, you could. Now do just as I tell you, Alice. When you’ve eaten, we’ll talk again.’ "Not a sign of a sign! And yet I'll swear it! Do you know where she's gone?" "Go along with your doctor," said Maitrank now, in great good humour. "If you will have the goodness to call a cab I will get back to my hotel." "I am...." “Bad news?” Larry asked, climbing to the turf. Larry braced himself against the slap of the wheels into the surface water. That might offer just enough resistance to nose them in. However, it ended, as soon as Mr. Everdail had sailed on the yacht to join his wife at their lakeside camp in Maine, uncanny light, odd noises and other strange things had become evident again, as an excited local correspondent had notified the paper. Reporters, searching, and watching, had found nothing so far but the public would be informed as soon as they discovered the secret. He believed that he had no ties now, that friendships, the love of woman, and the kiss of children all had missed him, and that his, thenceforth, must be but vain regret. So far as he knew, Felipa had gone away without ever having received his letter. The man he had intrusted it to had been killed in the Aravaypa Ca?on: that he was certain of; and it never entered his head that his papers might have fallen into other hands, and the note have finally been delivered to her. She was leading the sort of life that would most quickly put him entirely out of her mind. He was taking the Washington papers, and he knew. She had gone away, not even sure that he had given her a thought since the night in the Sierra Blanca when Black River had roared through the stillness, and they had been alone in all the wild world. What a weird, mysterious, unearthly scene it had been, quite outside the probabilities of anything he had imagined or contemplated for a single minute. He had never regretted it, though. He believed in impulses, particularly his own. Yet she not only loved Cairness as much as ever, but more. Her church had the strong hold of superstition upon her, but she might have thrown it off, grown reckless of enforced conventions, and have gone to him, had not faithfulness and gratitude held her yet more powerfully. "Yes, that is she; glad to see you back, Missy," said the General, patting the cow on the back. "Take her back and give her a good feed, if you can find it, for probably she's pretty hungry." Have you never heard of AMP burning them, you silly damn fool? Her young face bowed to his neck, and suddenly his lips crept round and lay against the coolness of her cheek. She did not move, and he still walked on, the grass splashing under his feet, the rabbits scampering round him, showing their little cotton-tails in the dark.
