Abstract
The invention discloses a production method of an automobile roof online coated with a carbon fiber composite. The production method includes HP-RTM and Surface-RTM forming processes. The production method includes the following steps that a preform is put on an HP-RTM clamping platform; the preform is grabbed by a mechanical hand and put in a forming die of the HP-RTM clamping platform; the HP-RTM clamping platform is controlled to enable the forming die to suffer from die closing; an HP-RTM glue injection system starts to inject resin into the forming die; after the resin is cured, the forming die is controlled to be in a semi-die-opening state, a Surface-RTM glue injection system injects surface coating resin into the forming die, and then the forming die suffers from die closing again;after the surface coating resin is cured, the finished automobile roof is formed, and the finished automobile roof is grabbed by the mechanical hand and put on a finished product conveying table; andthe finished automobile roof is conveyed by the finished product conveying table, and following procedures are carried out. The product produced with the production method is low in weight, the energy consumption is low, the full-automatic production process is high in efficiency, the quality is guaranteed, and the production method is suitable for volume production.
Description
technical field [0001] The present invention relates to the field of automobile parts production, in particular to an automobile roof part suitable for various motor vehicles and electric vehicles, especially the on-line coating of carbon fiber composite materials using HP-RTM molding process and Surface-RTM process Production method of a car roof. Background technique [0002] Most of the car roof is a metal structure and is formed by stamping. Its disadvantage is that it is heavy, which cannot meet people's demand for lightweight vehicles, and also increases energy consumption. Therefore, on the basis of meeting the basic performance requirements such as rigidity, strength and anti-collision of the top cover, it is urgent to carry out lightweight design to reduce energy consumption. At present, there are many plans to replace the metal roof structure with carbon fiber composite materials, and it has been practically applied in some models. [0003] At present, the carbo...
