[0002] Welding is a very important process in the automotive industry. During the welding process, welding stress is inevitably generated, and the resulting deformation directly affects the dimensional accuracy of the product. What is more serious is that it poses a potential risk to safety performance, reduces the bearing capacity of the structure, shortens the product life, or directly leads to scrapping.

[0003] The instrument panel crossbeam assembly is the most important assembly component in the automotive interior assembly. Many important components are installed on it, such as the steering wheel, CD player, air conditioning panel, air conditioning outlet, auxiliary airbag, etc. The reasonable design, overall beauty and performance of the instrument panel crossbeam directly determine the customer's intuitive evaluation of the vehicle performance. The instrument panel crossbeam is an important load-bearing component of the instrument panel assembly and one of the structural components. It is universal for a series of models on this platform.

[0004] At present, the dashboard crossbeam assembly is welded manually, and the manual operation method has the following problems: 1. After the parts are welded, they are very easy to deform during transportation, and the geometric dimensions are unstable, which affects the evaluation indicators such as assembly accuracy and surface difference, resulting in poor accuracy of the entire vehicle; 2. The welding quality is inconsistent and the production efficiency is low, and the amount of supporting welding tooling invested is relatively large. Summary of the invention

[0005] The utility model provides a vehicle instrument panel crossbeam assembly production line, aiming to solve the problems of low efficiency and poor quality in the existing production method.

[0006] In order to solve the above technical problems, the technical solution of the utility model is: a vehicle instrument panel cross beam assembly production line, characterized in that: it includes a welding room, the welding room is provided with a left tube beam production branch line, a right tube beam production branch line and a welding robot group, the left tube beam production branch line and the right tube beam production branch line are symmetrically arranged, and the left tube beam production branch line and the right tube beam production branch line share the welding robot group; the structure of the left tube beam production branch line: includes the 10th sequence station, the 20th sequence station, and the 30th sequence station arranged in sequence, and the 10th sequence station is used to The left mounting main bracket assembly, the right mounting main bracket assembly, the instrument upper body main mounting bracket assembly, and the instrument panel tube beam are welded into a whole to form the 10th sequence assembly; the 20th sequence station is used to weld the instrument panel sub-mounting bracket assembly, the steering column mounting bracket, and the tube beam connecting bracket group to the 10th sequence assembly to form the 20th sequence assembly; the 30th sequence station is used to weld the central control bracket assembly and the fuse box mounting bracket assembly to the 20th sequence assembly to form the 30th sequence assembly; the structure of the right tube beam production branch line is the same as that of the left tube beam production branch line.

[0007] The above technical solution is further limited in that the welding robot group includes an R1 welding robot, an R2 welding robot, and an R3 welding robot which are distributed in sequence; the 10th workstation shares the R1 welding robot, the 20th workstation shares the R2 welding robot, and the 30th workstation shares the R3 welding robot.

[0008] The above technical solution is further limited in that the supporting equipment of the welding room includes a smoke extraction device.

[0009] The above technical solution is further limited in that the supporting equipment of the welding robot group includes a welding robot control cabinet.

[0010] Beneficial effects: 1) The dashboard crossbeam assembly designed by the utility model avoids the problem of bumping or deformation during the long-distance transportation and transfer of the sub-assembly; 2) The use of robot welding can ensure the correct and stable angle of the welding gun, and the repeatability accuracy reaches 0.08%, which is conducive to the stability and control of geometric dimensions, avoids the problems of poor appearance such as weld depression and distortion in manual welding, and ensures the consistency of product welding quality; 3) The method of using two branch lines to share a welding robot group is about 3 times the efficiency of traditional manual welding, which improves production efficiency and reduces production costs.
