Description

Technical Field

[0002] LED display is a display method that controls semiconductor light emitting diodes. It is composed of tens of thousands or hundreds of thousands of semiconductor light emitting diode pixels evenly arranged. It uses different materials to produce LED pixels of different colors to display text, graphics, images, animations, quotes, videos, video signals and other information.

[0003] When producing some relatively thick LED display screens, in order to fit the back panel and other components of the display screen, the display screen needs to be flipped frequently.

[0047] Working principle: when in use, the transmission motor 108 is started, the transmission motor 108 drives the transmission driven wheel 107 to rotate, the transmission driven wheel 107 drives the transmission driving wheel 109 through the transmission belt 110, the transmission driving wheel 109 drives the transmission wheel 106 to rotate through the active transmission shaft 105, and the transmission wheel 106 drives the conveyor belt 111 to move;

[0048] When flipping, the display screen enters the conveyor belt 111, and the conveyor belt 111 drives the display screen to move backward until one side of the display screen enters the buffer sleeve 509. At this time, the display screen is just located between the four pressure plates 309, and then the clamping motor 307 is started. The clamping motor 307 drives the second rotating shaft 305 to rotate in the forward direction. The second rotating shaft 305 drives the second rotating shaft 305 on the same side to reverse synchronously through the meshing transmission between the synchronous gears 306, thereby closing the two inner parallel rods 304 on the same side, and then closing the docking seat 308 and the pressure plate 309, so as to clamp the display screen, and then start the flipping motor 203. The flip motor 203 drives the driving synchronous belt 205 through the active transmission wheel 204, and then drives the driven transmission wheel 202 through the driving synchronous belt 205, so that the flip intermediate shaft 201 rotates. When the flip intermediate shaft 201 rotates, the active flip wheels 208 at both ends drive the flip synchronous belt 210. The flip synchronous belt 210 drives the flip shaft 207 to rotate 180 degrees through the driven flip wheel 209, thereby driving the clamped display screen to rotate 180 degrees. At the same time, the display screen drives the flip frame 502 to flip 180 degrees and reposition it, and then the clamping motor 307 is started, and the clamping motor 307 is reversed. The second rotating shaft 305 is driven to rotate, and the second rotating shaft 305 drives the second rotating shaft 305 on the same side to reverse synchronously through the meshing transmission between the synchronous gears 306, so that the two inner parallel rods 304 on the same side are opened, and then the docking seat 308 and the pressure plate 309 are opened, so that the clamping of the display screen is released, and the released display screen is driven by the conveyor belt 111 to be transported backward until the display screen completely leaves between the pressure plates 309, and then the flip motor 203 is started to reverse, and the flip motor 203 drives the driving synchronous belt 205 through the active transmission wheel 204, and then drives the synchronous belt 205 to drive the rotating shaft 305 to rotate. The driving transmission wheel 202 causes the flip intermediate shaft 201 to rotate. When the flip intermediate shaft 201 rotates, the flip synchronous belt 210 is driven by the active flip wheels 208 at both ends. The flip synchronous belt 210 drives the flip shaft 207 to rotate 180 degrees in the opposite direction through the driven flip wheel 209, thereby realizing the resetting of the docking seat 308 and the pressure plate 309. Compared with directly continuing to rotate 180 degrees to reset, resetting by reversely flipping the docking seat 308 and the pressure plate 309 can bring the display screen back through the reverse resetting action when an error occurs in the output program of the display screen and the display screen is not disengaged, thereby avoiding the display screen from being broken by the forward resetting action.
