Description

Technical Field

[0001] The invention belongs to the field of LED display systems and relates to an LED ball curtain light panel replacement device. Background Art

[0002] The LED ball curtain light board replacement device is a tool or system specially used to replace the light board in the LED spherical screen (i.e., LED ball curtain). It is designed to simplify the maintenance process, improve the replacement efficiency, and ensure that other parts of the ball curtain will not be damaged during the replacement process. However, when replacing the LED light board at a high place, the existing LED ball curtain light board replacement device needs to use a ladder or scaffolding, and then use a suction cup to replace the LED light board. Not only is the operation inconvenient, but there is also a risk of falling and injury. In addition, the surface temperature of the LED ball curtain light board is high under high-intensity work for a long time. Direct disassembly in a high temperature environment will increase the operational risks, such as scalding the operator or damaging other parts on the light board. At the same time, dust, dirt and other impurities will accumulate on the surface of the LED ball curtain light board after long-term use. These dust and impurities will reduce the sealing of the suction cup when replacing it with a suction cup, resulting in a decrease in the suction force of the suction cup, making it impossible to easily replace the LED ball curtain light board.

[0037] The working principle of the LED ball curtain light board replacement device provided by the present invention is as follows: when replacing the LED ball curtain light board, firstly, the first motor 7 is started by the operating button 6 to drive the threaded rod 8 to rotate. Under the limit of the handle 1, the telescopic column 2 can move up and down, thereby adjusting the height of the device, and then the second motor 9 is started to drive the first rotating shaft 10 to rotate, drive the turntable 3 to rotate, so that the device can rotate, and start the third motor 11 to drive the first bevel gear 12 to rotate, so that the second bevel gear 13 and the rotating column 14 rotate, drive the support column 15 to rotate along the center of the rotating column 14, thereby adjusting the angle of the suction cup 17, and finally replace the specified LED light board. At this time, by starting the fourth motor 24, since the fourth motor 24 can automatically rotate forward and reverse frequently, it drives the second rotating shaft 25 to rotate back and forth, so that the third bevel gear 32 and the fourth bevel gear 33 rotate back and forth, driving the third rotating shaft 34 and the fan 21 to The fan 21 rotates back and forth to generate wind flow, and the convection and heat exchange effect of the wind flow are used to cool the surface of the LED lamp board, which not only prevents direct disassembly in a high temperature environment from scalding the operator or damaging other components on the lamp board, but also can blow away the dust in the middle of the LED lamp board. At the same time, the rotation of the second shaft 25 also drives the main pulley 26 to rotate back and forth, so that the secondary pulley 28 also rotates, driving the main roller 29 to rotate, so that the conveyor belt 30 moves back and forth, and the movable plate 20 moves accordingly, driving the fixed plate 18 to move back and forth, so that the soft brush 19 repeatedly wipes the dust on the surface of the LED lamp board to prevent these dust and impurities from affecting the sealing of the suction cup 17, resulting in a reduction in the suction force of the suction cup 17 and affecting the use of the device. After the surface of the LED lamp board is cooled and dusted, the movable plate 20 moves to the bottom of the return groove 22 and reaches the bottom of the support plate 4, so that it will not affect the use of the suction cup 17.
