Thermal edge-covering device for automobile roof skylight

Abstract

The invention discloses a thermal edge-covering device for an automobile roof skylight. The thermal edge-covering device for the automobile roof skylight comprises a rack, wherein the rack is provided with a locating part used for placing an automobile roof, a heating assembly used for heating an edge-covering base material, an edge-covering mechanism, a compensation mechanism and an edge-pressing mechanism, the edge-covering mechanism comprises four straight-edge inserts and a driving mechanism, an R-angle insert is arranged between every two adjacent straight-edge inserts, and the driving mechanism is used for driving the straight-edge inserts and the R-angle inserts to move horizontally and vertically; the compensation mechanism comprises compensation inserts and a compensation driving cylinder, when the straight-edge inserts and the R-angle inserts horizontally move outwards, gaps are formed between the two sides of each R-angle insert and the adjacent straight-edge inserts, and the compensation inserts are arranged in the gaps in a sliding fit mode; and the edge-pressing mechanism is used for pressing the folded and edge-covered base material. According to the thermal edge-covering device for the automobile roof skylight, a good edge-covering effect is achieved, edge-covering at the positions of the four R corners of the roof is smooth and does not bulge during edge-covering, and the appearance attractiveness of the edge-covered product is improved.

Description

technical field [0001] The invention relates to the technical field of automobile roof processing, in particular to a heat-wrapping device for an automobile roof sunroof. Background technique [0002] During the processing of the semi-finished car interior roof, the decorative fabric pasted on the inner surface of the sunroof frame of the semi-finished interior roof needs to be turned from the inner surface of the sunroof frame to the outer surface of the sunroof opening, and bonded to the outer surface of the sunroof frame . The existing ceiling fabric hemming usually needs to spray glue first, and then carry out flanging bonding. With the innovation of technology, some new composite fabrics have appeared, which are made of PU, glass fiber, fabric and PP. When this kind of fabric is bound and bonded, it does not need to be sprayed, and it is directly heated. The composite fabric will Hot melting occurs, and then it can be edge-wrapped and pressed, eliminating the need for...

Problems solved by technology

[0003] However, in the existing hot-sealing tooling structure, the structure is complex, and the hemming effect on the sunroof position of the car roof is poor, and the hemming at the four R corners of the roof skylight is not smooth, and the phenomenon of bulging is prone to occur, resulting in product hemming The rear appearance is poor in appearance and the pass rate is low
