However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0027] like Figure 1-Figure 6 As shown, the utility model provides a seamless liquid crystal splicing display device, comprising a display 1, on which a dust removal mechanism 2 is provided;

[0028] The dust removal mechanism 2 includes two motors 201, a fan 204 and a slide hole 205. The output ends of the two motors 201 are both equipped with a winding drum 202. The insides of the two winding drums 202 are both wound with steel wires 203. An air jet 207 is installed between one ends of the two steel wires 203. The output end of the fan 204 is equipped with a hose 206. The output end of the hose 206 is installed with the input end of the air jet 207. The input end of the air jet 207 is slidably connected to the inside of the slide hole 205. The fan 204 is installed on the top of the display 1. The slide hole 205 is opened on the front surface of the display 1 near the edge. The two motors 201 are symmetrically installed on the top of the display 1. The other ends of the two steel wires 203 are respectively installed with the inner walls of the two winding drums 202. The surface of the air jet 207 The display 1 is provided with an auxiliary mechanism 3, the auxiliary mechanism 3 comprises two slide grooves 301, the interiors of the two slide grooves 301 are slidably connected with sliders 302, a shell 4 is fixed on the top of the display 1, a shell cover 5 with holes is installed at the installation port of the shell 4, a perforated plate 6 is installed on the rear surface of the display 1, the front surfaces of the two sliders 302 are fixed to the surface of the jet pipe 207, the two slide grooves 301 are symmetrically opened on the front surface of the display 1, the input end of the hose 206 is movably sleeved inside the through hole of the shell cover 5 with holes, the hose 206 is movably sleeved inside the through hole of the perforated plate 6, the two motors 201, the two winding drums 202 and the fan 204 are all inside the shell 4, and the top of the jet pipe 207 is in contact with the bottom of the shell 4.

[0029] The effect achieved is that when the seamless liquid crystal splicing display device is installed at the desired position, the two motors 201 and the fan 204 are first connected to the external controller (PLC controller), and then the external controller is connected to the external power supply. Then the external controller is turned on, and the switching time of the two motors 201 and the fan 204 are set. The basic usage procedures, and then the perforated shell cover 5 and the perforated plate 6 are installed on the shell 4 and the display 1 respectively. When the forward rotation start time of the two motors 201 and the fan 204 are turned on, the two motors 201 and the fan 204 are turned on. When the start time arrives, the input end of the fan 204 that is started at this time will suck in air, and then the fan 204 will transport the sucked air to the inside of the hose 206, and then to the inside of the jet pipe 207, and then spray out from the air outlet of the jet pipe 207. At this time, the sprayed air can start to remove dust from the screen surface of the seamless liquid crystal splicing display device. At the same time, the two started motors 201 will drive the connected winding drum 202 to rotate, and unwind the corresponding steel wire 203. When the two steel wires 203 start When the wire is unwound from the corresponding winding drum 202, the air jet tube 207 and the two sliders 302 will directly move vertically downward under their own gravity, the sliding hole 205 and the two sliding grooves 301. At this time, the continuously moving air jet tube 207 can perform dust removal operation on the screen surface of the seamless liquid crystal splicing display device. When the reversal time set by the two motors 201 arrives, the dust on the screen surface of the seamless liquid crystal splicing display device has just been cleaned. At this time, the two motors 201 reversed at the output end will be connected to it. The winding drum 202, the corresponding steel wire 203, the two slide grooves 301, the two sliders 302 and the slide hole 205 cooperate to drive the jet tube 207 to reset and move. When the jet tube 207 resets and moves, the jet tube 207 that is reset will continue to eject the air inside the jet tube 207 from its output end, and the screen surface of the seamless liquid crystal splicing display device is dust-cleared again. When the jet tube 207 is reset to its original position, the external controller will directly turn off the two motors 201 and the fan 204 at the same time.

[0030] Working principle: When the seamless LCD splicing display device is installed at the desired location, first connect the two motors 201 and the fan 204 to the external controller (PLC controller), then connect the external controller to the external power supply, then turn on the external controller, set the switching time of the two motors 201 simultaneously forward and reverse, the switching time of the fan 204 and the basic usage procedures, then install the perforated shell cover 5 and the perforated plate 6 on the shell 4 and the display 1 respectively, when the forward rotation start time of the two motors 201 and the start time of the fan 204 When the time is reached, the input end of the fan 204 that is started at this time will suck in air, and then the fan 204 will transport the sucked air to the inside of the hose 206, and then to the inside of the jet pipe 207, and then spray out from the air outlet of the jet pipe 207. At this time, the sprayed air can start to remove dust from the screen surface of the seamless liquid crystal splicing display device. At the same time, the two started motors 201 will drive the winding drum 202 connected thereto to rotate, and unwind the corresponding steel wire 203. When the two steel wires 203 start to unwind from the When the corresponding winding drum 202 is unwound, the air jet tube 207 and the two sliders 302 will directly move vertically downward under their own gravity, the sliding hole 205 and the two sliding grooves 301. At this time, the continuously moving air jet tube 207 can perform dust removal operation on the screen surface of the seamless liquid crystal splicing display device. When the reversal time set by the two motors 201 arrives, the dust on the screen surface of the seamless liquid crystal splicing display device has just been cleaned. At this time, the two motors 201 reversed at the output end will be connected to it. The winding drum 202, the corresponding steel wire 203, the two slide grooves 301, the two sliders 302 and the slide hole 205 cooperate to drive the jet tube 207 to reset and move. When the jet tube 207 resets and moves, the jet tube 207 that is reset will continue to eject the air inside the jet tube 207 from its output end, and the screen surface of the seamless liquid crystal splicing display device will be dust-removed again. When the jet tube 207 is reset to its original position, the external controller will directly turn off the two motors 201 and the fan 204 at the same time.
