Four-station turntable type hot air welding machine and welding method thereof

Abstract

The invention belongs to the technical field of automobile part processing, and particularly relates to a four-station turntable type hot air welding machine and a welding method thereof. The four-station turntable type hot air welding machine comprises a machine frame with a working table board, and a turntable assembly, a hot air assembly and a riveting assembly which are arranged at the side ofthe turntable assembly are arranged at the machine frame. The four-station turntable type hot air welding machine has the advantages that automatic welding operation of a company mark and a company mark ring at a safety air bag cover can be realized, and the operation threshold is low, time and labor are saved in the welding process, and no harm is caused to workers in the welding process, and the welding quality of the company mark and the company mark ring can be effectively guaranteed. The welding method applying the four-station turntable type hot air welding machine comprises the following steps of 1) a pre-processing process; 2) a code scanning process; 3) a hot air process; 4) a riveting process; and 5) a shooting and discharging process. The welding method has the advantages thatthat the actual processing efficiency of the welding process is systematically improved.

Description

technical field [0001] The invention belongs to the technical field of auto parts processing, and in particular relates to a four-station turntable hot-air welding machine and a welding method thereof, which are applied to the welding of the logo on the cover of the airbag and the ring of the logo. Background technique [0002] In the field of auto parts processing, especially in the assembly of automobile airbag covers, it is often necessary to weld the airbag covers. Taking the welding process of the logo and logo ring at the airbag cover as an example, the shape of the logo and logo ring is as follows Figure 1-2 Shown, and the installation position of the relative airbag cover is as follows image 3 As shown, because the company logo and the company logo ring go deep into the airbag cover, the traditional welding method mostly uses manual operation for welding, and the welding method uses a hand-held hot air gun to directly press down, and cooperate with later knocking t...

AI Technical Summary

Problems solved by technology

The manual welding method is extremely dependent on the operator, not only is it difficult to guarantee the operation efficiency, but the operator also needs high professionalism

The professional quality of the operators is slightly poor, and the operation of the welding head is slightly improper. The surface of the welded product is easy to be uneven, and even problems such as overheating, welding penetration, desoldering and virtual welding will occur, which will affect the actual performance of the airbag cover.

At the same time, the smoke generated during the welding process is harmful to the human body, and the core area of ​​the hot air often cannot completely cover the entire logo or ring, which frequently appear in the welding process of the existing logo and ring. So it brings a lot of troubles to the actual welding operation
