Description

Technical Field

[0001] The utility model relates to the technical field of automobile film pasting equipment, in particular to an auxiliary film pasting device for an automobile A-pillar. Background Art

[0002] The application of black film in the decoration of A and B pillars of automobiles has low price, strong workmanship guarantee, and powerful decorative and protective effects compared to guard plates and paint, which expands the visual effect of windows and windshields. At present, black film has become the focus of automobile appearance design. On the production line of motor vehicle assembly plants, the film-applying station has become a necessary production link in the painting workshop.

[0003] like Figure 5 The figure shows an automotive A-pillar sheet metal C, the upper end of which is fixedly connected to the roof sheet metal B, and the lower end of which is fixedly connected to the fender flare sheet metal D. Because the side of the A-pillar sheet metal C facing the exterior of the vehicle body to which the black film is applied is a curved, irregularly shaped surface, and because the black film typically consists of a black film body, a release layer applied to one adhesive side of the black film body, and a protective film applied to the other side of the black film body, conventional film application tools are not suitable for film application.

[0004] Currently, applying black film to automobile A-pillars is commonly done manually. This process requires two operators: one operator holds the black film at both ends and stretches it flat, while the other operator removes the release paper. The two then work together to apply the black film to the A-pillar sheet metal, finally removing the protective film. The problems with manually applying film to automobile A-pillars are: Two operators are required per film application station, resulting in high labor costs; the success rate of manually applying black film to automobile A-pillars is only 40-50%, resulting in a large amount of black film being scrapped due to application failures, resulting in high material costs; and the low efficiency of manual black film application severely restricts the overall production efficiency of automobile paint shops. Therefore, the present invention proposes an auxiliary film application device for automobile A-pillars to address these technical issues. Summary of the Invention

[0005] The purpose of the present invention is to overcome the defects in the prior art and provide an auxiliary film-sticking device for automobile A-pillars. When in use, the first positioning seat is clamped on the outer edge surface of the position where the roof sheet metal and the upper end of the automobile A-pillar sheet metal are connected, and the second positioning seat is clamped on the outer edge surface of the position where the wheel eyebrow sheet metal and the lower end of the automobile A-pillar sheet metal are connected. Through holes are respectively provided at both ends of the black film and sleeved on the positioning pin 1 on the first positioning seat and the positioning pin 2 on the second positioning seat, so that the black film is unfolded and positioned correspondingly above the outer side surface of the automobile A-pillar sheet metal, and then the release layer on the lower side of the black film is torn off, and the scraper is used to press from the middle of the black film and continuously push the black film to both ends to flatten it. When applying the film to the end, remove the positioning seat one or the positioning seat two, then apply the black film end flat, and finally tear off the protective film, which significantly improves the adhesion flatness of the black film on the outer surface of the automobile A-pillar sheet metal, and the bubbles between the black film and the outer surface of the automobile A-pillar sheet metal can be effectively expelled during the film application process, ensuring the adhesion quality of the black film, reducing the adhesion scrap rate of the black film to less than 5%, and at the same time improving the adhesion efficiency of the black film; the operation is simple, and the requirements for the operator are low. The film application station only requires one operator to complete the adhesion of the black film on the automobile A-pillar sheet metal on the same side, which helps to reduce manpower input costs; the overall structural design is simple, the preparation and application implementation feasibility is high, and the practicability is strong.

[0006] To achieve the above-mentioned purpose, the technical solution of the present utility model is to design an auxiliary film-applying device for the A-pillar of an automobile, comprising a positioning seat 1, a positioning seat 2 and a connecting rod, wherein the positioning seat 1 comprises an L-shaped positioning plate, the lower side of the L-shaped positioning plate is provided with a curved surface structure 1 adapted to the outer side of the roof sheet metal, the L-shaped positioning plate comprises an arm plate 1 facing the front side and an arm plate 2 facing the side of the positioning seat 2, a plurality of positioning pins 1 are provided at intervals on the upper side of the arm plate 1, and the end of the arm plate 2 away from the arm plate 1 is provided with a limit block 1 extending downward and used for clamping on the outer edge surface of the roof sheet metal;

[0007] The second positioning seat includes a curved positioning plate, the lower side of which is provided with a second curved structure adapted to the outer side of the wheel eyebrow sheet metal, a plurality of positioning pins are provided at intervals on the side of the curved positioning plate, and a second limit block is provided at the rear end of the curved positioning plate, extending downward and being used to be clamped on the outer edge of the wheel eyebrow sheet metal;

[0008] One end of the connecting rod is fixedly arranged at the corner position of the side surface of the L-shaped positioning plate, and the other end is fixedly arranged at the rear end of the upper side surface of the curved positioning plate.

[0009] The utility model relates to an auxiliary film pasting device for automobile A-pillars.

When it is pushed to the end, the first positioning seat or the second positioning seat is pressed. The second positioning seat is removed, and then the end of the black film is applied flat, and finally the protective film is torn off, which significantly improves the adhesion flatness of the black film on the outer surface of the automobile A-pillar sheet metal. In addition, during the film application process, the bubbles between the black film and the outer surface of the automobile A-pillar sheet metal can be effectively expelled, ensuring the adhesion quality of the black film, reducing the adhesion scrap rate of the black film to below 5%, and at the same time improving the adhesion efficiency of the black film; the operation is simple and the requirements for the operator are low. Only one operator is needed at the film application station to complete the adhesion of the black film on the automobile A-pillar sheet metal on the same side, which helps to reduce manpower input costs; the overall structural design is simple, the preparation and application implementation feasibility is high, and it is highly practical.

[0010] A preferred technical solution is to have a first pad fixed to the upper side of the first arm plate, with several first positioning pins located on the upper end surface of the first pad; and a second pad fixed to the upper side of the curved positioning plate, with several second positioning pins located on the upper end surface of the second pad. Pads one and two cooperate to ensure a suitable gap (typically 10 to 20 mm) between the black film positioned and flattened on the first and second positioning seats and the outer side of the corresponding A-pillar sheet metal. This facilitates removal of the release layer from the underside of the black film, ensuring convenient and efficient application.
