Technical Field

[0001] The utility model relates to the technical field of spliced ​​display screen assembly mechanisms, in particular to a spliced ​​display screen assembly mechanism. Background Art

[0002] At present, with the development of display technology, display screens are applied in more and more occasions, and the market and customers have put forward higher requirements for various performances of display screens: not only stable product performance is required, but also high product assembly efficiency and low labor cost. In the prior art, taking LED display screens as an example, LED display screens are assembled and spliced ​​by multiple LED display units.

[0003] A Chinese patent with announcement number CN212484812U discloses a spliced ​​display screen assembly mechanism, including a display screen fixing frame for installing the display screen, a CCD camera detection module, a light source irradiation device, a processor for information processing control, a receiving display electrically connected to the processor, and other structures. The utility model can detect the gaps existing in the installation process of the display screen by photographing through the CCD camera detection module, and the gaps can be more intuitively observed by the operator on the receiving display, thereby making it more convenient for the operator to perform installation and debugging.

[0004] However, the above patent can only take photos to detect a single spliced ​​screen, and the user cannot check the overall situation of the installed spliced ​​screen. In fact, only checking the offset of a single spliced ​​screen can easily make the gap size between each group of spliced ​​screens different. There is no standard value, which will also cause the gap between each group of spliced ​​screens to be different. However, after the installation is completed, the user needs to disassemble the spliced ​​screen on a large scale after discovering the error through naked eye observation, which brings certain adverse effects to people's use process. In order to solve the shortcomings of the prior art, we propose a spliced ​​display screen assembly mechanism. Utility Model Content

A rotation groove is provided between the transmission rod 11 and the first movable frame 8, and the transmission rod 11 and the first movable frame 8 are movably connected through the rotation groove. The transmission belt 3 and the transmission device 9 are meshed. The transmission belt 3 can be a transmission chain. The transmission device 9 can be a combination of a group of gears and a group of connecting rods. The transmission chain and the gear are meshed. A connecting rod is fixed inside the gear. The lower end of the connecting rod is welded to the first screw rod 5. The gear is driven to rotate through the transmission chain, thereby driving the connecting rod and the first screw rod 5 to rotate.

[0025] It should be noted that the utility model is a splicing display screen assembly mechanism. When in use, after each splicing screen 2 is spliced, the PLC control system controls the laser light tube 16 to turn on, and according to the position of the splicing screen 2, the position of the CCD zoom camera 15 is changed by controlling the first motor 4 and the second motor 14. The first motor 4 drives the transmission device 9 to rotate, and the transmission device 9 drives the transmission belt 3 to rotate, so that the first screw 5 and the second screw 6 rotate synchronously in the same direction at the same speed, so that when the first movable frame 8 changes its height, the left and right ends will not tilt, and the second The motor 14 drives the transmission rod 11 to rotate, and the transmission rod 11 drives the second movable frame 12 to move left and right, thereby driving the CCD zoom camera 15 and the laser lamp tube 16 to change their positions at the same time. At this time, the laser lamp tube 16 will scan multiple groups of spliced ​​screens 2 to compare whether the vertical laser line is perpendicular to the edge of the spliced ​​screen 2. At the same time, the CCD zoom camera 15 takes pictures to determine the gap between the spliced ​​screens 2, and the image captured by the CCD zoom camera 15 each time is transmitted to the receiving display in the PLC control system, which is convenient for the operator to adjust the spliced ​​screen.
