Problems solved by technology

[0002] Car roof is an important part of automotive interior products, generally divided into two types of roofs with sunroof and without sunroof; in order to achieve the effect of beautiful appearance and reliable performance of the roof and sunroof, the existing roof with sunroof and skylight There are mainly the following two production methods: one is to wrap the edge of the sunroof (including two types of edge wrapping and robot edge wrapping); the other is to directly cut the cut of the roof skylight with a robot, and the roof will be cut after loading. Cooperate with the sunroof by sealing strips; they all have some defects or deficiencies to varying degrees, such as the influence of the fabric structure during the hemming treatment, the quality of the hemming is not easy to control, the development cycle of the skylight is long, and the development investment cost is high. The clearance of the sunroof is unstable, the production efficiency is low, the assembly efficiency of the whole vehicle is reduced, and the scrap rate is high, etc.

Embodiment Construction

[0010] In order to better understand the present invention, it will be further elaborated below in conjunction with specific examples.

[0011] The cooperating production process of the passenger car non-woven fabric ceiling and the outward-opening sunroof according to the present invention is mainly that the cutout of the ceiling sunroof is covered with a skeletonless PVC sealing strip, and the front of the sealing strip and the cutout of the ceiling sunroof is covered with a suitable adhesive. Bond polyester fiber and PVC double-sided tape, such as tesa double-sided tape, and the sealing strip and the back of the skylight cutout are fixed with hot-melt adhesive suitable for bonding polyester fiber and PVC, such as 3M hot-melt adhesive; specifically match the production process The order is as follows: firstly, the cut ceiling semi-finished product is cleaned, burr trimmed, and the cutout of the skylight is polished, and the raw edge and the double-sided tape are ironed before...

Abstract

The invention discloses a matched production technique for a non-woven fabric ceiling and an externally-opened skylight of a passenger vehicle, in particular a matched production technique for a non-woven fabric ceiling and an externally-opened skylight, and belongs to the technical field for producing the interior ceiling products of the vehicle. The invention is characterized in that a PVC sealstrip without a skeleton is used for coating the cuts of the ceiling and the skylight; the seal strip is fixed with the front surface of the cuts of the ceiling and the skylight by a double sticky tape and is fixed with the back surface of the cut of the skylight by a hot cement; the technique includes the four steps of pre-treating the semi-finished product of the ceiling, sticking the double sticky tape, mounting the seal strip and manufacturing a finished product. The product manufactured by the technique is characterized by beautiful and elegant appearance, special sculpt, reasonable structure, safety and environment protection, stable size and performances, and the like. The matched production technique is suitable for the ceilings of the passenger vehicles of middle and top grades.
