Method for producing anatomy car trim ceiling through dry process

Abstract

The invention discloses a method for producing an anatomy car trim ceiling through dry process and belongs to the technical field of automotive trim manufacturing. The method comprises the steps of heating a base material; bonding the base material with non-woven fabric through a die to form a ceiling prototype; cutting the ceiling prototype with a cutting robot, wherein the size obtained after cutting is consistent with that of the anatomy car ceiling; spraying the surface of a ceiling intermediate product with polyurethanes or neoprene misty glue, and then bonding the ceiling intermediate product with knitted fabric through the die to form an initial finished anatomy car ceiling product; sticking the knitted fabric to the back side of the ceiling intermediate product to form the finished anatomy car ceiling product. By the adoption of the technical scheme, the size and appearance quality of the anatomy car trim ceiling are both improved remarkably, and bonding between the base material and fabric as well as between the fabric and the knitted fabric is firm; meanwhile, the whole production process can be completed with one die, and profile consistency and production cost minimization are guaranteed.

Description

technical field [0001] The invention relates to the technical field of automotive interior processing and manufacturing, and more specifically relates to a production method suitable for dry-process anatomical vehicle interior ceilings. Background technique [0002] At present, auto shows and other places often use dissected cars for display, and there is no relatively mature production technology for the interior ceiling of dissected cars. The existing technology is: 1) After heating the base material, the base material and the fabric are pressed together through a mold to form the initial state ceiling with waste; 2) The initial state ceiling is cut by a robot on a special model, Form the ceiling product; 3) According to the size of the anatomical vehicle data, manually mark the cutting position on the back of the ceiling; 4) Use a knife to cut the ceiling from the middle by manual cutting to form the finished product of the anatomical vehicle ceiling. [0003] The disadv...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the low dimensional accuracy, poor appearance quality, unsatisfactory bonding effect between the base material and the fabric, and between the fabric and the knitted fabric in the prior art and the inability to rely on the same mold to complete the anatomical car interior ceiling. Dissecting the shortcomings of the production process of the dry process of the car roof, a production method suitable for the dry process of dissecting the car interior ceiling is provided. The technical solution of the present invention makes the size and appearance quality of the dissected car interior ceiling It has been significantly improved and the bond between the base material and the fabric, and between the fabric and the knitted fabric is firm, so that the produced anatomical car roof has a good molding effect. At the same time, the production process of the anatomical car roof can be completed by relying on the same mold , to ensure consistent profiles and minimize production costs
