超聲波焊接原理

超聲波焊接的産品無壓痕、燙傷的“秘密武器”

超聲波焊接后，经常会见到産品表面局部位置有压痕或烫伤，影响美观。一般对于内部元件，轻微压伤可以接受；但对于外观件，无法接受。往往会在焊头与産品之间放一张保护膜，也叫做缓冲片。起到缓冲作用，保护零件表面不受损伤。

什么是保护膜？它是一种透明的塑料膜，很薄并有一定的韧性。可以是人工或者自动放置在焊头与産品之间，也可以提前吸附在零件表面。用于保护膜的材料不应与焊接零件相同。一般选择PE材料。也可以选择PET，但是后者价格较贵。

保護膜的作用是什麽？

保护膜有助于减少注塑件因缺陷和变化（翘曲和变形）可能产生的不良影响，填补産品轮廓和零件表面的空隙，并有效减少局部的接触压力。大大减轻压伤或者烫伤的问题。

什么样的零件需要保护膜？大多数零件外观都受益于保护膜的使用。一般来说，内部成本高的电子産品，例如个人电子産品，医疗设备，汽车控制和仪器仪表零件，需要使用保护膜。还有外观要求高的消费品，如家用电器，电子産品，车灯外饰件等，也需要使用保护膜。手边没有专门的保护膜，有没有其它替代方案？有，可以使用PE保鲜膜或者保鲜袋，可采用加厚、单层或者多层，对零件进行保护测试。

超聲波焊接后産品出现毛边或溢料如何进行处理？

‘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.
