Vehicle door sealing strip pasting and mounting system and pasting method

Abstract

The invention relates to the field of vehicle production auxiliary processing, in particular to a vehicle door sealing strip pasting and mounting system and a pasting method. The pasting and mounting system comprises a connecting plate unit, a feeding unit, a buffering unit, a material conveying unit, a discharging unit and a protective belt recycling unit. Sealing strips enter the pasting and mounting system from the feeding unit and pass through the buffering unit, and buffering storage materials are formed in the buffering unit. On one hand, the buffering storage materials are conveyed outwards by the buffering unit, and on the other hand, the buffering storage materials are pulled upwards by the material conveying unit, so that the sealing strips are conveyed to the discharging unit. At the discharging unit, the protective belts of the sealing strips are peeled off, the pasting faces of the sealing strips are attached to a vehicle door, and the protective belts are guided to be collected by the protective belt recycling unit. According to the pasting and mounting system, the sealing strip installing and rolling steps are synchronously processed, the installing efficiency is improved, it is guaranteed that the vehicle door sealing strip pasting speed and the rolling head discharging speed are the same, the sealing strips are prevented from being stretched in the installing process, and the sealing strip and vehicle door pasting firmness is guaranteed.

Description

technical field [0001] The invention relates to the field of auxiliary processing for automobile production, in particular to a system for pasting and installing a door weather strip, and a pasting method using the system for pasting and installing the door weather strip. Background technique [0002] Door seals are widely used in various types of vehicles, and are mainly used to optimize and improve the dustproof and noise-proof performance of the vehicle and the closing force of the door. At present, door seals are mainly divided into two types: snap-on type and stick-on type. Among them, stick-on seals are more widely used and have better effects, especially for relatively high-end models, such as Volkswagen, Mercedes-Benz, BMW, Hongqi and other brand models. Adhesive door sealing strip is to install the sealing strip on the door by pressing or rolling with a special adhesive tape, such as 3M's ST1200, 4112 and other types of common adhesive tape. [0003] Since the door...

Problems solved by technology

[0003] Since the door sealing strip is in the shape of a loop, the main installation methods at present are: one is manual placement and manual rolling. This form of installation method is difficult to guarantee the installation accuracy, and it is time-consuming and labor-intensive.

The second is to adopt the pressure plate type. This method is the installation method of most automobile manufacturers at present. This method can ensure the installation accuracy, but it requires people to cooperate with the installation of the formed sealing strip. The requirements for the production of the sealing strip in the early stage are relatively high. Guarantee the length, accuracy and cost of the sealing strip, and the applicability is relatively low, and the model is only applicable

[0008] However, the above-mentioned sealing strip bonding equipment lacks the matching of the sealing strip sticking speed and the sealing strip discharge speed on the one hand, and it is difficult to ensure the sealing effect of the sealing strip; The integration of the device is difficult to adapt to the production beat of the fully automatic assembly line
