Description

[0001] The present invention relates to a CFRP product line lay-out for carbon fiber reinforced plastic products,

The invention relates to a line arrangement structure for performing machining and quality inspection on a CFRP processed member. More particularly, the present invention relates to a processing and quality inspection line arrangement structure that is automatically performed by an industrial robot.

The use of robots to process workpieces, blanks, or semi-finished parts in the manufacturing process is expanding. Today's manufacturing methods often consist of placing finished or semi-finished parts of a robot on a belt conveyor, where the quality inspection is carried out subsequently by the user. An example of a manufacturing process is a press-shop. Automation of the press line typically ends with a robot or manipulator unloading the manufactured parts from the last press to the belt conveyor. Automation of the press shop is often completed by placing manufactured parts stamped into a designated rack to be transferred to the body-shop area. In the case of a skin panel, one of the reasons for not automatically placing parts into the rack from the last press is that it is first necessary to perform a surface quality inspection. Thus, today's approach consists of a robot placing parts on a belt conveyor, where the quality inspection is performed by the user. If the part quality is within the correct parameters, the operator (s) takes the part into the corresponding rack or container; Move the part to be racked or, if possible, automatically put into the rack by the robot. In this last case, the operation may actually be complicated because the robot responsible for the operation must first locate the part on the conveyor to pick it up correctly. The component may be unstable and may require a complicated device with a triple band belt conveyor that can adjust the height of the center band to provide the necessary stability to prevent component flow. Finally, a visual system, perhaps a 3D or mechanical centering device, will be required to position or center the part. A system for producing a manufacturing part comprising at least one industrial production process having a handling tool for picking up manufacturing parts in Korean Patent No. 10-0093168 (entitled " quality control system and method of manufacturing parts ") Characterized in that the robot is arranged in a quality inspection cell and the robot is programmed to maintain the manufactured part in at least one known location of the quality inspection cell and to provide the manufactured part for quality inspection. System is disclosed.

The CFRP processing member is formed of CFRP (carbon fiber reinforced plastic), and the carbon filament is made into a winding shape or a fabric shape, and then the resin is impregnated and cured.
