Description

Double-skylight car roof edge covering device with jacking mechanism

Technical Field

The invention belongs to the technical field of automobile decoration, and particularly relates to a double-skylight vehicle roof edge covering device with a jacking mechanism.

Background

In the processing process of the automobile roof, the decorative fabric adhered to the inner surface of the skylight opening of the semi-finished automobile roof needs to be turned over from the inner surface of the skylight opening to the outer surface of the skylight opening and adhered to the outer surface of the skylight opening. The multi-purpose taping device is now done automatically.

In a conventional hemming device, for example, chinese patent CN104162978A discloses a hemming device for hemming a roof having a sunroof opening, wherein a hemming block is moved forward outward to push a rim material of the sunroof opening outward from an inner surface of the sunroof opening to an outer surface of the sunroof opening, so that the rim material is adhered to the sunroof opening pre-coated with an adhesive, and a pressing block is moved forward inward to press the rim material against the outer surface of the sunroof opening.

However, the hemming device in the related art has the following problems:

after the flanging blocks finish advancing, because the adjacent corner flanging blocks and the edge flanging blocks are separated to generate intervals, the tension applied to the corner rim material of the corner positioned at the skylight opening part and the tension applied to the edge rim material of the edge positioned at the skylight opening part are uneven and discontinuous, and the corner rim material and the outer surface of the skylight opening part are bonded irregularly and are easy to wrinkle.

When the rim charge is turned over from the inner surface of the opening part of the vehicle window to the outer surface of the opening part of the vehicle window, because the rim charge is in a free state, a flanging crease formed after the rim charge is flanged is difficult to be completely matched with the shape of the opening part of the vehicle window, and therefore the turned rim charge is not orderly bonded with the outer surface of the opening part of the skylight, is easy to wrinkle, and is not attractive in edge covering outline.

When the roof has two skylight openings, one side of one skylight opening is adjacent to one side of the other skylight opening in parallel, and because the space between the two skylight openings is limited, the existing pressing part is difficult to be arranged in the limited space to finish the pressing action of the edge materials corresponding to the two adjacent sides in parallel.
