Abstract
Description
[0001] This invention relates to a computer-controlled system for repairing accident damage to vehicle bodies using 3D printing methods.
[0002] 3D printing devices are currently used in many industries, including for the production of some vehicle parts.
[0003] However, the repair of accident damage to vehicle bodies, where replacing damaged body parts is impossible or too expensive, is done manually.
[0004] The invention is based on the objective of creating a system for repairing accident damage to vehicle bodies using 3D printing processes.
[0005] An example implementation is described below. Fig. 1 described.
[0006] It shows: Fig. 1 Block diagram of the device
[0007] The invention comprises: The frame (1). The following units are installed on the frame (1): (2) Device for receiving and immovably fixing a vehicle or vehicle body or body part. (3) 3D scanner (4) 3D pushers (5) Device for marking the area of damage to a vehicle body. (6) Device for milling and grinding (7) Computers with appropriate programs Operating principle of the device
[0008] The system is computer-controlled and operated with the participation of the operator.
[0009] A damaged vehicle or its body is installed in the working area of the device and secured against movement using the device for receiving and fastening(2).
[0010] A 3D scanner (3) scans the surface of a damaged vehicle body and transmits information to a computer (7) which uses the program to create a 3D surface model. The program compares the 3D model of the scanned damaged vehicle body with the 3D model of the manufacturer's vehicle body or undamaged vehicles.
[0011] Areas on a vehicle body whose surface has deviations are defined as damage, and their shape is marked on the body with a damage marker (4).
[0012] The damage is divided into two types: bulging and dent zones, which are marked with different colors.
[0013] The program determines the type of surface damage as a bulge or dent.
[0014] The program then recommends that the operator remove protrusions on the body. The operator removes the protrusion by mechanical deformation. The removal of the protrusions is confirmed by the operator with a corresponding order (command) via the computer.
[0015] The 3D scanner rescans the damaged area and informs the operator if no bulges are present. The program then calculates the position, size, and shape of the 3D patch (bandage) and displays it on the computer screen.
[0016] The operator can make changes to the 3D model of the patch on the computer. Once the 3D model is complete and the surface of the body is prepared for 3D printing, the operator sends the print command to the 3D printer. After 3D printing is finished, the repair area is scanned again and the scanned image is compared. If necessary, the repair area is machined using a computer-controlled milling and grinding machine. Afterward, the vehicle or its body is removed from the machine's work area and taken to the paint shop.
