Before coding, the marking head is moved so that the positioning surface of the marking head positioning tooling contacts the plane of the frame coding position to avoid collision between the marking head and the frame when the whole equipment is moved. After coding, the marking head is moved backward to avoid the interference position with the frame.

[0088] The lifting column 121 can accurately adjust the Z-axis position of the marking head, which can not only meet the requirements of coding at different heights, but also enable the marking head to avoid the interference position with the frame.

[0089] The mobile trolley can move the entire laser coding equipment to meet the coding requirements at the side beams and beams of the frame.

[0090] The control cabinet 40 is composed of a cabinet, a controller, a light source, a UPS power supply, an electrical control system and an industrial computer (with a display screen), and is the brain of the entire device.
