The present invention provides an ultrasonic welding device and an ultrasonic welding system, configured to prevent bending of a welding subject or generation of softening at an undesired part of a surface of a welding subject. An ultrasonic welding device according to one aspect of the present invention includes a horn for pressing a first member to ultrasonic-weld the first member and a second member to each other, the horn includes a knurling part having a plurality of protrusions configured to protrude toward the first member in order to form an uneven shape on the first member, and the length (m) by which each of the plurality of protrusions protrudes toward the first member may be equal to or larger than the thickness of the first member. La présente invention concerne un dispositif de soudage par ultrasons et un système de soudage par ultrasons, conçus pour empêcher la déformation d'un objet à souder ou la génération d'un ramollissement au niveau d'une partie non souhaitée d'une surface d'un objet à souder. Un dispositif de soudage par ultrasons selon un aspect de la présente invention comprend un pavillon destiné à appuyer sur un premier élément pour souder par ultrasons le premier élément et un second élément l'un à l'autre, le pavillon comprenant une partie moletée possédant une pluralité de saillies conçues pour faire saillie vers le premier élément afin de former une forme irrégulière sur le premier élément, et la longueur (m) sur laquelle chaque saillie de la pluralité de saillies fait saillie vers le premier élément peut être égale ou supérieure à l'épaisseur du premier élément. 본 발명은 피용접물의 표면의 원하지 않는 부분에 연화가 발생하거나 피용접물이 휘는 것을 방지하도록 구성된 초음파 용접 장치 및 초음파 용접 시스템을 개시한다. 본 발명의 일 측면에 따른 초음파 용접 장치는 제1 부재와 제2 부재를 초음파 용접하기 위하여 상기 제1 부재를 가압하는 혼을 포함하고, 상기 혼은 상기 제1 부재에 요철 형상을 만들기 위하여 상기 제1 부재를 향해 돌출되도록 구성된 복수개의 돌기를 구비하는 널링부를 포함하고, 상기 복수개의 돌기 각각은, 상기 제1 부재를 향해 돌출된 길이(m)가 상기 제1 부재의 두께보다 크거나 같을 수 있다.
