Description

Technical Field

[0001] The utility model relates to the technical field of automobile interior decoration manufacturing, in particular to an automobile instrument panel airbag frame mesh cloth cutting system. Background Art

[0002] In the production process of automotive airbag frames, cutting and testing the airbag frame mesh are key steps to ensure quality and safety. Currently, three methods are commonly used in the industry: closed laser cutting, hot knife cutting, and cold knife cutting. Each of these methods has its advantages and disadvantages, but all have some shortcomings:

[0003] Closed-loop laser cutting technology utilizes a high-energy laser beam for precise cutting, adapting to the cutting needs of a wide range of products. However, this method requires manual intervention to place and retrieve parts, making it difficult to fully integrate into a fully automated production line. Furthermore, the membrane needs to be frequently replaced to accommodate the cutting of different products, which not only increases operational complexity but also equipment costs. Most importantly, relying on manual visual inspection for error prevention makes it difficult to effectively prevent misdetection and the outflow of unqualified products.

[0004] Hot knife cutting technology heats the blade to a high temperature and then uses it to cut the mesh. This technology allows for fully automated operation and improves production efficiency. However, if the equipment or production line experiences an emergency stop, the still-hot hot knife could continue to burn the mesh, posing a fire hazard. Similarly, manual visual inspection cannot completely eliminate false positives and the outflow of defective products.

[0005] Cold knife cutting uses mechanical tools at room temperature and can also be fully automated. However, the cutting process is prone to producing foreign matter such as debris and burrs, which can cause burns during airbag deployment, posing a safety threat to the vehicle and passengers. As with the other two methods, manual visual inspection after cold knife cutting cannot fully guarantee product quality, resulting in false detection and the outflow of defective products.

[0006] Therefore, there is an urgent need for a car instrument panel air bag frame mesh cutting system. Utility Model Content
