Cooperated technique for producing passenger car nonwoven cloth ceiling and exterior open type dormer windows

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 seal strip 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.

Description

1. Technical field [0001] The invention discloses a cooperating production process of a passenger car ceiling and a sunroof, in particular a cooperating production process of a non-woven fabric ceiling and an outwardly opening sunroof, and belongs to the technical field of processing and production of vehicle interior roof products. 2. Background 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.

[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.
