Description

Modular laser cutting apparatus with easy replacement and detachment The present invention relates to a modular laser cutting device that is easy to separate and replace. With the number of self-employed individuals recently exceeding 4.22 million, various small-scale manufacturing and creative activities are becoming more active. Along with this, the demand for laser cutting devices is surging, and inexpensive Chinese equipment is rapidly dominating the domestic market through a massive influx. The problem lies in the fact that these low-cost devices rely solely on price competitiveness without relying on core technologies or precise application designs. As a result, the domestic laser machinery industry, which has grown based on advanced technologies from the United States, Japan, and Germany, is facing a serious threat, and there are growing concerns that the technological level and safety of the entire industry could be jeopardized. Furthermore, laser cutting devices are inherently large and heavy, making it difficult to transport or install them as finished products. For small-scale creators or self-employed individuals with limited workspace, this imposes significant constraints on equipment placement, and subsequent maintenance is inevitably difficult and inefficient. In addition, the reality that at least one dedicated operator must be assigned to each machine due to the risk of fire from high-temperature lasers in the event of a malfunction places a heavy burden on both labor costs and safety management. The proliferation of mass-produced equipment lacking technological capability, along with structural issues regarding safety, space, and operation, now demands the emergence of new laser processing solutions that are user-friendly, stable, and flexible.
