Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, in particular to a laser cutting device for sheet metal processing. Background Art

[0002] Sheet metal processing refers to a series of processing operations on metal sheets to form the required parts or structures. In the process of sheet metal processing, laser cutting is often required. Laser cutting technology can focus into an extremely small light spot to achieve micro and precision processing, such as the processing of micro narrow slits and micro holes. Laser cutting machines have extremely high flexibility in the sheet metal processing industry and can meet diverse production needs.

[0003] The workbench on the bed of the laser cutting equipment on the market is designed as an integral structure, so that the sheet metal parts can only perform a single forward and backward action on the workbench. It is impossible to realize partition processing operations when processing sheet metal parts, and it is impossible to perform processing with different requirements on the bed. The finished product can only be unloaded after the subsequent cutting of the sheet metal parts on the bed is completed. Otherwise, it will affect the cutting work of other sheet metal parts on the workbench. It is impossible to carry out cyclic loading and unloading operations without stopping the machine, which reduces the processing efficiency and is inconvenient for the staff to carry out subsequent loading and unloading work.

[0004] Based on the above technical problems, the prior art also provides some solutions. For example, the Chinese patent with the authorization announcement number CN116748669B discloses a laser cutting device for sheet metal processing. The workbench on the bed of the present invention is composed of a No. 1 conveyor table and a No. 2 conveyor table. The workstations of the No. 1 conveyor table and the No. 2 conveyor table can be interchanged on the bed under the drive of the conveying unit on the bed, so that the sheet metal parts can be processed in different areas. At the same time, the sheet metal parts processed on the No. 1 conveyor table and the No. 2 conveyor table can be moved to the unloading area for unloading, thereby improving the overall processing efficiency. There is no need to stop the bed as a whole for unloading, and non-stop processing is realized. The loading and unloading between the No. 1 conveyor table and the No. 2 conveyor table are circulated, which provides convenience for the operation of the processing personnel.

[0005] However, in actual production operations, when the above-mentioned device uses laser cutting, the laser beam irradiates the object being cut, causing it to partially heat, melt or vaporize, thereby generating a large amount of waste gas and waste slag. Both the waste slag and waste gas will affect the human respiratory system, and the waste slag scattered on the surface of the processing table requires the operator to use a separate cleaning tool to collect and clean it, which is time-consuming and labor-intensive.
