The invention relates to the technical field of automobile plastic product welding, in particular to an automobile engine trim cover with sound-absorbing cotton and a welding process thereof.The automobile engine trim cover with the sound-absorbing cotton is characterized in that a trim cover body provided with a connecting rubber sleeve is placed on a lower ultrasonic welding tool, the sound-absorbing cotton is arranged above the trim cover body in a sleeving mode, an ultrasonic welding machine is started, an upper ultrasonic welding tool moves downwards, and the trim cover body is welded to the lower ultrasonic welding tool; the sound-absorbing cotton is pre-pressed by the multiple pre-pressing heads, then the ultrasonic welding upper tool continues to descend to the descending limit with the adjustable limiting structure, welding is started at the corresponding point positions of the ultrasonic welding machine, the sound-absorbing cotton is welded and fixed to the engine trim cover body at a time, the labor cost is reduced, and the working efficiency is improved. Only one operator is needed to meet the production and delivery of a batch-produced engine trim cover, the efficiency is improved by 80%, and the cost is obviously reduced. And meanwhile, compared with manual operation, the equipment tool and the process have higher stability, so that the stability of the welding quality is better.

    本发明涉及汽车塑胶产品焊接技术领域,具体涉及一种带有吸音棉的汽车发动机装饰罩及其焊接工艺,将装好连接胶套的装饰罩本体置于超声波焊接下工装上,吸音棉套入装饰罩本体上方,启动超声波焊机,超声波焊接上工装下行,多个预压头将其进行预压紧,然后超声波焊接上工装继续下行带可调限位结构到下行极限后,超声波焊机对应点位启动焊接,一次性将吸音棉焊接固定在发动机装饰罩本体上,降低人工成本,只需要一个操作人员即可满足一个批量生产的发动机装饰罩的生产交付,效率提升80%,明显降低成本;同时因设备工装及工艺相对人工操作具有更高的稳定性,故其对焊接质量的稳定性更好。
