Description

Technical Field

[0001] This utility model relates to the field of aluminum plate processing, specifically to an infrared detection device for the dropping of circular pieces during laser cutting of aluminum plates. Background Technology

[0002] In aluminum plate processing, laser cutting is widely used for cutting aluminum plate discs due to its advantages such as high cutting precision, high efficiency, and smooth cut edges. In actual cutting operations, the aluminum plate is usually fixed on the cutting worktable, and the laser cutting head cuts the aluminum plate into discs. After cutting, the discs fall into a collection mechanism below the worktable under their own gravity.

[0003] However, in existing aluminum plate laser cutting processes, there is a lack of effective real-time detection methods to ensure that the discs fall smoothly after cutting. When discs become stuck in the cutouts of the cutting table, adhere to the aluminum substrate, or fail to fall accurately into the collection mechanism, operators cannot detect it in time. If such problems are not addressed promptly, subsequent cutting operations will be severely affected. Furthermore, manual inspection of disc drop status is labor-intensive. Therefore, those skilled in the art have provided an infrared detection device for disc drop during aluminum plate laser cutting to solve the problems mentioned in the background art.
