超聲波焊接原理

“超聲波”焊线的设计对産品的影响

超聲波焊接都是通过移动两个焊接零件的焊接端面分子，使它们相互扩散和缠结。以达到互连的目的。超聲波焊接是利用焊头的高频振动使两个焊接部件在高频下发生摩擦，从而将机械能转化为热能。热能溶解两个焊接表面上的分子以恢复其活性。然后，借助外力使分子相互缠结，达到焊接的目的。实际上，不难理解焊接是导致分子相互缠结的过程。

对于易于通过超聲波焊接的塑料（如ABS，PC，HIPS等），通常按以下方式设计焊线接头形式：

超聲波焊線設計一：

该超聲波焊接线的设计不适用于超聲波焊接。因为焊接时间长，焊接能量大，焊接后溢流周围有熔化的胶水，影响産品的外观。

超聲波焊線設計二：

改进的超聲波焊接线设计，通常制作一个小的三角形骨骼，这将减少焊接能量和时间，但是仍然会出现少量的飞边，影响外观。

超聲波焊線設計三：

通常情況下，爲了防止膠水的溢出影響外觀，我們必須如圖所示將其制成，然後將超聲波導線放在擋塊內以防止塑料熔體溢出。

超聲波焊線設計四：

当産品的壁厚不足以形成止动结构时，为了防止塑料熔体溢出并影响外观，我们通常按照图所示制作産品结构，并制作一个闪光收集器以防止不良现象

超聲波焊線設計五：

经验丰富的设计师应该知道，没有艺术线条的産品很可能在组装变形后导致上盖和下盖未对准，从而导致划痕。超聲波是相同的，并且可能会出现未对准的情况。为了防止刮擦，最好在上面做些美术线条。

“超聲波”传感器的性能及工作准则

‘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.
