On-line remanufactured production method based on automatic identification of multiple models in main line buffer area

Abstract

The invention discloses an online remodeling production method based on the automatic identification of multiple vehicle models in the main line buffer area, including step 1: the central control enters the barcode of the specially modified vehicle into the system in advance according to the production order, and sets a special buffer lane for the rebuilt vehicle, a buffer lane for non-reformed vehicles and Straight channel; Step 2: After welding, the body-in-white of the car enters the cache lane, and the automatic identification device recognizes the vehicle barcode; Step 3 judges whether remanufacturing is required, if so, the body-in-white enters the special cache lane for remanufactured vehicles and executes step 4, if not, enters the non-remanufactured vehicle The vehicle is cached and executed in step 6; step 4: the body-in-white enters the remodeling station for remanufacturing; step 5: the body-in-white enters the straight channel after remodeling; step 6: the body-in-white is welded at the welding station; step 7: the body-in-white is transported to Surface adjustment on the first floor; Step 8: Install the door cover, surface finishing; Step 9: Transfer the body-in-white to the second floor for submission. The invention realizes the production mode of online remodeling by establishing an aerial remodeling area, improves efficiency and can deal with various remanufactured models.

Description

technical field [0001] The invention relates to an automobile body-in-white assembly production method, in particular to an online remanufacturing production method based on automatic identification of multiple vehicle models in a main line buffer area. Background technique [0002] At present, domestic mainstream commercial vehicle companies generally do not have the production capacity to carry out remodeling on the production line of OEMs. The production mode of rebuilt vehicles is generally to enter a specific refitting factory for remodeling after the complete vehicle is rolled off the assembly line; Specially modified vehicles are special-purpose vehicles that are restructured after the basic vehicle is rolled off the assembly line; similarly, a commercial model of another automobile company is also restructured as a special-purpose vehicle after the entire vehicle is rolled off the assembly line; The restructuring period is long and the cost is high, so it is not suit...

AI Technical Summary

Problems solved by technology

[0005] 1. In the existing mode, the off-line and on-line of the whole vehicle are carried out at the elevator at the end of the surface adjustment line. The line speed of the elevator and the speed of the surface adjustment plate chain are linked, so the surface adjustment line speed is pulled during the entire on-line and off-line projects. Stopping, every time a body-in-white goes on and off the production line, the mediation line is about 8 minutes, and the production capacity of 5 vehicles is lost, and energy and labor hours are seriously wasted, which has a great impact on the production capacity of the base model

[0006] 2. The off-line process of the body-in-white in the existing mode: firstly pull the stop watch to adjust the line and adjust the elevator to the specified height, then open the safety door of the elevator and push the transfer trolley to the side of the elevator, and then at least 6 people work together to push the body-in-white to the transfer trolley Finally, push the body-in-white to the lift in the designated remodeling area next to the line. The whole vehicle process requires 6 people and takes about 20 minutes to complete. The labor time of those who make larger vehicles is wasted.

[0007] 3. The current mode is to go off the assembly line after the whole vehicle is assembled with four doors and two covers and the whole vehicle is intensively repaired. Secondary quality defects, and there may be interference after assembly, causing at least 10 minutes of labor-hour waste for each car

[0008] 4. In the existing mode, manual identification of the configuration sheet is used, which is prone to identification omissions or errors, resulting in the body-in-white being submitted to the painting workshop, and then the vehicle is transferred back to the body workshop, which will waste a lot of man-hours
