Description

Technical Field

[0001] This utility model relates to the field of display screen production equipment technology, and in particular to a display screen outer frame transportation device. Background Technology

[0002] An LED display screen is a display device composed of a large number of light-emitting diodes (LEDs) arranged in a certain pattern. It displays various information such as text, images, and videos by controlling the on / off state, brightness, and color of each LED. This type of display screen is widely used in many fields such as advertising, stage backgrounds, sports scoring, and traffic information display. In the assembly process of an LED display screen, the support frame must first be assembled according to the size and shape of the display screen. The frame is usually made of metal and has sufficient strength and stability to support the weight of the entire display screen. Then, the soldered PCB modules need to be installed on the frame. During this process, positioning fixtures are used to position and fix the support frame of the LED display screen.

[0003] Currently, Chinese patent CN217022599U discloses a display screen frame transport vehicle, which includes a base that can roll or slide along the ground. Multiple limiting members are evenly arranged on the surface of the base to limit the bottom beam of the display screen frame. Each limiting member is parallel to the others, and its extension direction is consistent with the direction in which the bottom beam of the display screen frame is installed on the base of the transport vehicle. A locking groove, adapted to the size of the bottom beam of the display screen frame, is formed between the limiting members. The bottom beam of the display screen frame can be installed in the locking groove, thereby limiting the display screen frame and preventing it from moving or shaking on the base.

[0004] Although the display frame transport vehicle has the advantages of simple structure, convenient use and ability to prevent the display frame from moving or shaking on the base, the display frame still needs to be moved by hand-pushed transport vehicle. The entire transportation process relies on manual labor to transport the outer frame of the display to the designated processing station, which is inefficient. Utility Model Content
