Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile door processing auxiliary equipment, and specifically relates to a tool for pasting sound insulation cotton on automobile door waterproof film. BACKGROUND

[0002] As one of the important parts of the automobile sealing system, the door waterproof film is a key part to ensure the sealing performance of the door and has an important influence on the air tightness of the vehicle. The door waterproof film is one of the important parts of the door system design due to the influence of the door sheet metal, door system parts, door electrical harness and other factors. The automobile door waterproof film is pasted on the inner side of the door sheet metal, and the rainwater on the door glass penetrates through the sealing rubber strip to the inner sheet metal of the door, flows to the waterproof film, and flows to the outside through the water flow hole. The waterproof film avoids the penetration of rainwater into the cab during this process, thereby achieving the effect of waterproof sealing, and preventing dust, oil stains and other impurities from entering the vehicle.

[0003] With the development of automobile manufacturing technology, various functional styles of automobiles are increasing, and more and more functional components are installed on the inner side of the automobile door sheet metal. Since the automobile waterproof film is only fixed on the specific position of the inner side of the automobile door sheet metal by peripheral pressure connection or adhesion, and the functional components are mostly distributed in the gap between the automobile waterproof film and the inner side of the automobile door sheet metal. During the driving of the automobile, it is found that the components installed on the inner side of the automobile door sheet metal are prone to resonance noise with the corresponding automobile door waterproof film. In order to solve this problem, a certain thickness of sound insulation cotton is pasted between the automobile door waterproof film and the inner side of the automobile door sheet metal to limit the resonance noise caused by the close approach of the automobile door waterproof film to the corresponding functional components.

[0004] At present, the sound insulation cotton is generally bonded between the automobile door waterproof film and the inner side of the automobile door sheet metal by "visual positioning + manual pasting". The problem of this pasting method is that the positioning accuracy of the sound insulation cotton is poor, and sometimes the sound insulation cotton pasted between the automobile door waterproof film and the inner side of the automobile door sheet metal will interfere with the functional components installed on the inner side of the automobile door sheet metal. At this time, the sound insulation cotton needs to be torn down and re-pasted. In the process of tearing the sound insulation cotton from the automobile waterproof film, the automobile door waterproof film is easily partially torn, thereby increasing the scrap rate of the automobile door waterproof film and increasing the production and processing cost of the automobile door. In addition, the "visual positioning + manual pasting" method has slow visual positioning speed and low overall pasting efficiency, which seriously restricts the pasting efficiency of the automobile door waterproof film on the automobile door sheet metal. Therefore, the utility model provides a tool for pasting sound insulation cotton on the automobile door waterproof film to solve the above problems. SUMMARY
