[0002] A distribution box is an electrical equipment used to distribute electrical energy. It has the characteristics of small size, easy installation, and unique functions. It is mainly used to control, distribute power, and protect electrical equipment, as well as to prevent line overload, short circuit, and leakage. Distribution boxes are widely used in various places such as schools, hospitals, and factories to facilitate the display and management of the conduction status of circuits. During the production and processing of distribution boxes, a cutting device needs to be used to cut the metal sheet to obtain the distribution box shell.

[0003] The existing distribution box shell cutting device is mainly composed of the following key parts: laser, frame, workbench, guide rail, motor, etc. Its working principle is that the laser generates a laser beam, which is focused and guided by the optical system to form a high-energy density laser beam. The mechanical structure drives the laser head to move according to the instructions of the control system. Under the irradiation of the laser beam, the metal sheet on the workbench is quickly melted, vaporized or reaches the ignition point, thereby achieving cutting.

[0004] The distribution box shell cutting device in the existing technology currently has the following disadvantages: the metal jet generated when the laser cuts the metal plate will adhere to the support plate of the workbench and is difficult to clean. Failure to clean in time will cause the surface of the workbench to be uneven, resulting in a decrease in the cutting accuracy of the metal plate, seriously affecting the quality and appearance of the distribution box shell, and the metal jet may form sharp edges or protrusions, which may scratch the operator's skin or pierce the equipment or cables during work, causing equipment failure or short circuit, thereby causing safety accidents such as fire or electric shock; therefore, an automatic cutting device for the distribution box shell is proposed to address the above problems.
