[0060] In one embodiment, Figure 2 As shown, the transmission device 10 includes: a transverse transmission device 11 and a longitudinal transmission device 12. Among them:

[0061] The transverse transmission device 11 is used to drive the assembly and disassembly device 20 to move transversely relative to the splicing display device according to the control command of the control device 50. The transverse transmission device 11 at least includes: an overhead crane device 111, a transverse guide rail device 112, and an overhead crane driving device (not shown). The transverse guide rail device 112 is installed on the upper edge of the splicing display device or behind the upper part of the splicing display device. The overhead crane driving device drives the overhead crane device 111 to move transversely along the transverse guide rail device 112 according to the control command of the control device 50, and the assembly and disassembly device 20 is driven to move transversely in front of the splicing display device through the cooperation of the overhead crane device 111 and the transverse guide rail device 112. Preferably, the overhead crane driving device is a driving motor.

[0062] The transverse guide rail device 112 includes a transverse guide rail 1121 and a support mechanism 1122 (such as Fig.13 As shown). The transverse guide rail 1121 is installed on the upper edge of the spliced ​​display device or the rear of the upper part of the spliced ​​display device, spanning the entire spliced ​​display device, and is used to allow the overhead crane device 111 to move laterally along the transverse guide rail 1121, so that the overhead crane device 111 can move from the left end of the screen body to the right end of the screen body or from the right end of the screen body to the left end of the screen body, thereby driving the disassembly and assembly device 20 to move laterally on the screen body. The support mechanism 1122 is used to fix the transverse guide rail 1121 on the steel structure 900. Preferably, the transverse guide rail 1121 is an I-beam guide rail.

[0063] The overhead crane device 111 moves laterally along the transverse guide rail 1121 under the drive of the overhead crane driving device 113. The overhead crane device 111 is fixedly engaged with the disassembly and assembly device 20, and according to the control instruction of the control device 50, the overhead crane device 111 hides the disassembly and assembly device 20 behind the splicing display device, or makes the disassembly and assembly device 20 climb over to the front of the splicing display device and move in front of the splicing display device.

[0064] The overhead crane device 111 comprises: an overhead crane 1111, a cable rail storage box 1112, a lifting device 1113, a cable output module 1114, and a cantilever device 1115. The cable rail storage box 1112 and the lifting device 1113 are sequentially mounted on the overhead crane 1111, and the cable output module 1114 and the cantilever device 1115 are sequentially mounted on the lifting device 1113. The cable rail storage box 1112 is used to store cable rails. The overhead crane 1111 moves laterally along the transverse guide rail 1121, and controls the retraction and release of the cable rails stored in the cable rail storage box 1112. The cable output module 1114 is provided with a first sliding mechanism 11141, and the cantilever device 1115 is provided with a second sliding mechanism 11153. The cable rails coming out of the cable rail storage box 1112 can pass through the first sliding mechanism 11141 and the second sliding mechanism 11153 in sequence without obstacles. Preferably, the first sliding mechanism 11141 and the second sliding mechanism 11153 may be pulleys.

[0065] The bottom of the overhead crane 1111 is equipped with a plurality of driving wheels (not shown) and a plurality of small wheels (not shown). The plurality of driving wheels are installed at the front and rear ends of the bottom of the overhead crane 1111 to drive the other small wheels to move horizontally. The overhead crane 1111 is meshed with the transverse guide rail 1121, and the meshing form is that the driving wheels and small wheels on the overhead crane 1111 are hidden inside the I-beam guide rail to prevent the driving wheels and small wheels from loosening and falling off.

[0066] The lifting device 1113 is used to fix and install the cantilever device 1115, and to lift and lower the cantilever device 1115 according to the control command of the control device 50, to lift the cantilever device 1115 to a certain height so that the disassembly and assembly device 20 pulled by the cantilever device 1115 is higher than the splicing display device, or to lower the cantilever device 1115 to a certain height so that the disassembly and assembly device 20 pulled by the cantilever device 1115 is hidden behind the splicing display device. The lifting device 1113 includes a lifter 11131, a plurality of lifting arms 11132, and a lifting platform 11133. The lifter 11131 is installed on the side of the overhead crane 1111, and drives the plurality of lifting arms 11132 to lift and lower according to the command of the control device 50. One end of the plurality of lifting arms 11132 is installed in the lifter 11131, and the other end is fixedly installed with the lifting platform 11133. The lifter 11131 is connected to the lifting platform 11133 through a plurality of lifting arms 11132, and is used to control the lifting of the lifting arms according to the control instructions of the control device 50, so as to lift the cantilever device 1115. The cable-out module 1114 is installed on the lifting platform 11133.

[0067] The cantilever device 1115 is installed on the lifting platform 11133, and includes a cantilever rod 11151 and a rotating shaft 11152. The rotating shaft 11152 is installed on one end of the cantilever rod 11151, and the second sliding mechanism 11153 is installed on the other end. The rotating shaft 11152 is installed on the lifting platform 11133. The cantilever rod 11151 is installed on the lifting platform 11133 through the rotating shaft 11152, so that the cantilever rod 11151 can rotate around the rotating shaft 11152.

[0068] Through the cooperation of the lifting device 1113 and the cantilever device 1115, the disassembly device 20 can be hidden behind the spliced ​​display device, and when necessary, the disassembly device 20 can be flipped over to the front of the spliced ​​display device. Preferably, the flipping form includes at least one of the following: flipping over from the top edge of the spliced ​​display device, flipping over from the side edge of the spliced ​​display device, flipping over from the inside of the spliced ​​display device, and flipping over from the bottom of the spliced ​​display device.

[0069] The longitudinal transmission device 12 is used to make the disassembly and assembly device 20 move longitudinally in the splicing display device. The longitudinal transmission device 12 includes: a cable rail 121 and a pulling device 122. The cable rail 121 is stored in the cable rail storage box 1112, and the overhead crane drives the cable rail to be retracted and released according to the control command of the control device 50. It can be retracted and released from the cable rail storage box 1112 without obstacles, and sequentially passes through the first sliding mechanism 11141 and the second sliding mechanism 11153 to connect with the pulling device 122. The pulling device 122 is installed at one end of the cable rail 121, and is used to cooperate with the fixed end reserved at the bottom of the steel structure, so as to straighten the cable rail 121.

[0070] The cable rail 121 is stably engaged with the assembly and disassembly device 20, so that the assembly and disassembly device 20 is stably fixedly engaged with the cable rail 121. The engagement form is that the cable rail 121 is engaged with the wheel of the assembly and disassembly device, and its form includes but is not limited to a toothed wheel, a threaded wheel, a flat wheel, etc. The engagement enables the assembly and disassembly device 20 to be stably fixed on the cable rail 121, and supports the movement of the assembly and disassembly device 20 on the cable rail, and its movement includes climbing and descending processes.

[0071] In the process of making the disassembling device 20 climb over to the front of the splicing display device, the cantilever device is lifted to a certain height by controlling the lifting and lowering of a plurality of lifting arms installed on the periphery of the overhead crane, so that the disassembling device pulled by the cantilever device is higher than the splicing display device. At this time, if the cantilever rod of the cantilever device is tilted forward, the disassembling device can be moved to the front of the splicing display device; if the cantilever rod is tilted backward, the disassembling device can be moved to the rear of the splicing display device.

[0072] When the disassembly and assembly device climbs over to the front of the splicing display device, the overhead crane controls the cable rail in the cable rail storage box to continuously lengthen according to the control instruction of the control device 50, so that the disassembly and assembly device engaged in the cable rail continuously descends due to the continuous lengthening of the cable rail. When the cable rail descends to the lower edge of the screen body, the traction device installed at the end of the cable rail cooperates with the fixed end reserved at the bottom of the steel structure to straighten the cable rail. After the cable rail is straightened, the detection device and the disassembly and assembly device will proceed to the next step. At this time, the force to straighten the cable rail does not need to be very large, just to ensure that the cable rail will not swing to a certain extent due to the external environment. When the disassembly and assembly device is adsorbed on the splicing display device, its adsorption force can also easily overcome the pulling force brought by the straightened cable rail.

[0073] When the disassembly device needs to be hidden behind the splicing display device, the overhead crane controls the cable rail in the cable rail storage box to lengthen a small section according to the control instruction of the control device 50, so that the clamping structure of the traction device and the steel structure is loosened, and then the cable rail is controlled to shrink continuously, so that the disassembly device engaged with the cable rail is continuously raised due to the continuous shortening of the cable rail. After the disassembly device rises to a position higher than the splicing display device, the cantilever rod is controlled to tilt backward, so that the disassembly device moves to the rear of the splicing display device, and then the lifting and lowering of the plurality of lifting arms installed on the periphery of the overhead crane is controlled, so that the disassembly device pulled by the cantilever device 1115 is hidden behind the splicing display device.

[0074] Furthermore, the fixed end reserved at the bottom of the steel structure, i.e., the end of the cable rail at the bottom of the screen body, is placed on a guide rail, so that when the overhead travelling vehicle moves laterally, the cable rail as a whole can also move laterally. Preferably, the fixed end can be locked by a hook lock, electromagnetic or the like.

[0075] In the transmission process of the transmission device, the horizontal direction facing the splicing display device is the X-axis, the vertical direction is the Y-axis, and the height is the Z-axis. The overhead crane is used to solve the X-axis displacement of the disassembly and assembly device, the cable rail is used to solve the Y-axis displacement of the disassembly and assembly device, and the cantilever rod is used to solve the Z-axis displacement of the disassembly and assembly device and the detection device. In this way, the movement control of different axes is distinguished by different structural operations. The movement control of the X-axis is provided by the horizontal operation of the overhead crane. At this time, the work of the overhead crane drive device and the work of the reducer are the key to controlling the movement accuracy. To ensure the accuracy of the movement distance of the overhead crane is to ensure the accuracy of the movement of the transmission device in the X-axis direction.

[0076] In one embodiment, Figure 3 As shown, the disassembly and assembly device 20 is used to stably fix the display unit. During the installation process of the entire spliced ​​display device, the disassembly and assembly device 20 installs the display units one by one on the steel structure, and during the disassembly process of the spliced ​​display device, the display units are disassembled one by one from the steel structure, and during routine maintenance work, a faulty display unit is disassembled from the steel structure. The disassembly and assembly device can realize the disassembly and installation of the display unit on the steel structure, avoiding wear caused by direct contact with the display unit.

[0077] The disassembly and assembly device 20 includes a clamping and positioning structure 21 , an adsorption device 22 , an unlocking mechanism 23 , and a clamping and fixing structure 24 .

[0078] The clamping and fixing structure 24 can stably fix the display unit, and includes a frame 241 and a guide rail (not shown) disposed in the frame 241. The guide rail is used to slide the display unit into the frame 241. The frame 241 is used to stably fix the display unit.

[0079] like Figures 4 to 5 As shown. The clamping and positioning structure 21 is fixedly mounted on the clamping and fixing structure 24, specifically fixedly mounted on one side of the frame 241 of the clamping and fixing structure 24, and is used for clamping and fixing with the top of the display unit 810. The specific fixing position is to cooperate with the frame of the display unit 810 (for example, on the square steel 830 at the top rear end of the display unit 810), so that the display unit is stably fixed on the clamping and positioning structure 21. The clamping of the display unit can be achieved by fixing the clamping and positioning structure on the square steel at the rear end of the display unit, thereby avoiding the wear of the display unit caused by direct contact between the display unit and the square steel.

[0080] The clamping and positioning structure 21 includes: an electromagnetic spring lock 211, a base 212, a lifting receiving plate 213, a lifting spring 214, a receiving beam 215, and a control docking stud 216. Among them:

[0081] The electromagnetic spring lock 211 is installed at the lower part of the clamping and positioning structure 21 and can be nested in the frame 241 to cooperate with the reserved hole 832 on the square steel 830 of the display unit. By inserting the electromagnetic spring lock 211 into the reserved hole 832, the clamping and clamping operation of the clamping and positioning structure is completed, so that the display unit can be stably fixed on the clamping and positioning structure.

[0082] The lifting spring 214 is used to provide elastic force for the electromagnetic spring latch 211, so that the electromagnetic spring latch 211 can be lifted and lowered more quickly.

[0083] The lifting receiving plate 213 is used to fix the electromagnetic spring lock 211 and provide lifting operation for the electromagnetic spring lock 211, so that the electromagnetic spring lock 211 can be lifted and lowered along with the lifting and lowering of the lifting receiving plate 213.

[0084] Preferably, the lifting receiving plate 213 uses one of the following methods to realize the lifting operation of the electromagnetic spring lock 211: using a lifting rod, a screw rod, electromagnetic adsorption, and rope pulling. When the electromagnetic spring lock 211 is received in the disassembly and assembly device 20, the lifting spring 214 is in a compressed state, providing a reaction force, and the disassembly and assembly device 20 overcomes the reaction force brought by the lifting spring 214 to complete the lifting of the disassembly and assembly device 20. The purpose of lifting is to align the electromagnetic spring lock 211 with the reserved hole 832 of the display unit square steel 830. After the lifting force disappears, the electromagnetic spring lock 211 can be directly and quickly inserted into the reserved hole 832 to realize the positioning and installation of the display unit.

[0085] The receiving beam 215 is fixed on the base 212 and is used to withstand the pulling force from the lifting receiving plate 213 and the elastic force of the lifting spring 214 .

[0086] The control docking stud 216 is used to cooperate with the control device 50, receive the control signal sent by the control device 50, and realize the control of the electromagnetic spring latch 211. The specific process is: when the electromagnetic spring latch 211 is inserted into the reserved hole 832 of the square steel 830, the electromagnetic spring latch 211 is subjected to the electromagnetic adsorption force during the insertion process, and its card plate will shrink to a position smaller than the aperture. After passing through the reserved hole 832, the electromagnetic coil is powered off, the magnetism disappears, and the card plate is stretched to the outside of the aperture by the spring elastic force, so that the display unit is fixed on the clamping and fixing structure, and the display unit is fixed.

[0087] The base 212 is used to provide a restraining force for the electromagnetic spring latch 211 to restrain the clamping plate, and to wrap up the entire clamping and positioning structure, thereby encapsulating the entire clamping and positioning structure as a whole.

[0088] like Figures 8 to 11The electromagnetic spring lock 211 includes a positioning stud 2111 , a top shell 2112 , an electromagnetic coil 2113 , an iron core 2114 , a telescopic frame base 2115 , a telescopic frame 2116 , a spring 2117 , a clamping plate 2118 , and a bottom shell 2119 .

[0089] The positioning stud 2111 is located at the top of the electromagnetic spring latch 211 and is screwed into the lifting receiving plate 213 for positioning and matching, so that the electromagnetic spring latch 211 can rise and fall with the lifting and falling of the lifting receiving plate 213.

[0090] The top shell 2112 is used to cooperate with the reserved hole 832 of the square steel 830 on the display unit during the clamping and positioning process.

[0091] The iron core 2114 is connected to the bottom of the top shell 2112 and is used to wind the electromagnetic coil 2113 so that the electromagnetic coil 2113 can generate electromagnetic attraction when powered.

[0092] The telescopic frame 2116 cooperates with the spring 2117 to quickly push the clamping plate 2118 outward to complete the opening action.

[0093] The telescopic frame base 2115 is located outside the iron core 2114 and provides support for the telescopic frame 2116 .

[0094] The clamping plate 2118 is nested in the end of the electromagnetic spring clamping lock 211, and when extended, it can cooperate with the square steel 830 at the rear end of the display unit to achieve clamping and fixing.

[0095] The bottom shell 2119 is used to provide a supporting force for the telescopic frame base 2115 during the clamping process to prevent the telescopic frame 2116 and the telescopic frame base 2115 from breaking during the clamping process.

[0096] Specifically, the electromagnetic spring latch 211 has two states: a contracted state and an open state. The difference between the two states is the contraction and opening of the latch plate 2118. Figure 8 and Fig. 9 The electromagnetic spring latch 211 is in a retracted state, that is, the latch plate 2118 is retracted to within the overall size of the electromagnetic spring latch 211; Fig.10 and Fig.11 The electromagnetic spring latch is shown in the open state, that is, the clamping plate 2118 is opened to the outside of the overall size of the electromagnetic spring latch 211. At this time, half of the protruding part of the clamping plate 2118 will bear the square steel surface to hold up the entire display unit or position the display unit.

[0097] Specifically, the contraction and opening of the electromagnetic spring latch 211 depends on whether the electromagnetic coil 2113 is energized. When the electromagnetic coil 2113 is energized, a strong electromagnetic adsorption force will be generated in the electromagnetic coil 2113, and the card plate 2118 will contract under the action of the electromagnetic adsorption force. At this time, the card plate 2118 contracts to within the overall size of the electromagnetic spring latch 211, so that the electromagnetic spring latch 211 is separated from the square steel reserved hole of the display unit, and the display unit is disassembled from the clamping and fixing structure, and the display unit is disassembled. When the electromagnetic coil 2113 is de-energized, the elastic force of the spring 2117 can quickly push the card plate 2118 outward to complete the opening action, so that the card plate 2118 is opened to outside the overall size of the electromagnetic spring latch 211. At this time, half of the protruding part of the card plate 2118 will bear the square steel surface, lift the entire display unit or position the display unit, and fix the display unit on the clamping and fixing structure to complete the fixation of the display unit.

[0098] like Figure 3 The adsorption device 22 is mounted on the outer edge of the frame 241 of the clamping and fixing structure 24, and stably meshes with the cable rail 121, so that the adsorption device 22 is stably fixed and meshed on the cable rail 121, and the meshing form is that the adsorption device 22 is meshed with the wheel of the cable rail 121, and the form includes but is not limited to a toothed wheel, a threaded wheel, a flat wheel, etc. The meshing enables the adsorption device 22 to be stably fixed on the cable rail 121, and supports the movement of the adsorption device 22 on the cable rail 121, and the movement includes the climbing and descending process.

[0099] The adsorption device 22 includes a telescopic device 221, a permanent magnet 222 and a plurality of electromagnets 223. The telescopic device 221 includes an X-shaped telescopic arm 2211, which can be telescoped from the center to the surroundings to form an X shape, and the telescopic range is adapted to the size of the display unit. Preferably, the telescopic range of the telescopic arm 2211 is larger than the display unit to be disassembled and assembled, and specifically, the inner edge thereof is exactly the outer edge of the four legs of the display unit.

[0100] The detection device 40 is installed at the center of the X-shaped telescopic arm 2211. The permanent magnet 222 has a relatively weak magnetic property and is nested on the detection device 40, and is first in contact with the screen body for adsorption; the plurality of electromagnets 223 have a relatively strong magnetic property and can generate a strong adsorption force after being energized, and are respectively nested at the top ends of the X-shaped telescopic arm 2211, and are used to energize and adsorb according to the instructions of the control device 50 after the telescopic device 221 completes the clamping size adaptation, so as to generate a strong adsorption force, which can adsorb the display unit to prevent it from falling, thereby completing the adsorption action of the display unit.

[0101] like Figure 3As shown. The unlocking mechanism 23 is arranged on the adsorption device 22, and is specifically arranged at each top end of the X-shaped telescopic arm 2211 of the telescopic device 221. The unlocking mechanism 23 includes an unlocking pin 231, a telescopic structure (not shown), and a rotating motor (not shown). Among them, the unlocking pin 231 is accommodated in the telescopic structure, and is used to be inserted into the unlocking hole 820 of the display unit to unlock the display unit from the steel structure. The telescopic structure can be extended and retracted according to the instructions of the control device 50. When unlocking, it extends outward, and after the unlocking is completed, it retracts inward. The rotating motor is used to drive the unlocking pin 231 to rotate in a preset direction so that the unlocking pin 231 is pulled out of the unlocking hole 820. Preferably, the preset direction is counterclockwise, and the rotating motor drives the unlocking pin 231 to rotate in a counterclockwise direction so that the unlocking pin 231 is pulled out of the unlocking hole 820.

[0102] In the embodiment of the present invention, a locking mechanism for locking and fixing each display unit is provided on the steel structure. In the display unit, a plurality of unlocking holes 820 (e.g., 4 unlocking holes) matching the above-mentioned locking mechanism are preset at the four positions on the front of the display unit. By inserting the unlocking pin into the unlocking hole 820, the display unit can be unlocked from the locking mechanism of the steel structure. Preferably, 4 unlocking holes 820 are preset at the four corners on the front of the display unit, and the aperture size of each unlocking hole is 2 mm.

[0103] The unlocking pin 231 is arranged on the adsorption device 22, specifically, it is arranged on each top end of the X-shaped telescopic arm 2211 of the telescopic device 221, matching the position of the unlocking hole of the display unit. The axial diameter of the unlocking pin 231 is equal to or slightly smaller than the aperture of the unlocking hole 820 of the display unit, and the number of the unlocking pins 231 matches the number of the unlocking holes 820.

[0104] When the display unit needs to be unlocked, after the unlocking pin is positioned by the positioning device, the telescopic structure extends outward according to the command of the control device, so that the unlocking pin is inserted into the corresponding unlocking hole, and the display unit can be unlocked from the locking mechanism of the steel structure. At this time, the display unit is slowly pulled out by the force of the unlocking pin and the unlocking hole. Because the inner edge of the frame of the clamping and fixing structure of the disassembly and assembly device is reserved with a corresponding guide rail, the display unit can be pulled out in the Z-axis direction with less resistance, so the cooperation force of the unlocking pin and the unlocking hole can pull out the display unit. After the display unit is pulled out onto the disassembly and assembly device, the electromagnetic spring lock in the disassembly and assembly device is inserted into the reserved hole on the square steel of the display unit. When the electromagnetic spring lock is inserted into the reserved hole of the square steel, the electromagnetic spring lock is subjected to the electromagnetic adsorption force during the insertion process, and its card plate will shrink to a position smaller than the aperture. After passing through the reserved hole, the electromagnetic coil is powered off, the magnetism disappears, and the card plate is stretched outside the aperture by the spring elastic force. Half of the protruding part of the card plate will bear the square steel surface of the display unit, lift the entire display unit or position the display unit, thereby fixing the display unit on the clamping and fixing structure, and completing the fixation of the display unit. At this time, the permanent magnet of the adsorption device lightly contacts the surface of the display unit. Due to the weak magnetism of the permanent magnet, the contact force between the permanent magnet and the surface of the spliced ​​display device in the display unit is not very large, so that the display unit slowly contacts the adsorption device, which acts as a buffer for the strong adsorption of the electromagnet and will not damage the spliced ​​display device in the display unit. After the permanent magnet contacts the surface of the display unit, the electromagnet is energized to adsorb the display unit, so that the adsorption device and the display unit cooperate with each other. After the cooperation is completed, the display unit is fixedly adsorbed on the adsorption device of the disassembly and assembly device. At this time, the control device controls the rotary motor to drive the unlocking pin to rotate counterclockwise, and controls the telescopic structure to retract inward to pull the unlocking pin out of the unlocking hole. At this time, the entire disassembly process of the display unit is completed.

[0105] When the display unit needs to be installed, the locking mechanism of the steel structure is positioned by the positioning device, and the position to be installed is confirmed. The adsorption device adsorbs the display unit to be installed, and is moved by the conveying device to the positioned steel structure installation position. After reaching the installation position, when the electromagnetic coil of the electromagnetic spring lock is energized, the electromagnetic coil generates a strong electromagnetic adsorption force, so that the card plate is contracted to within the overall size of the electromagnetic spring lock by the electromagnetic suction force, so that the electromagnetic spring lock is disengaged from the square steel reserved hole of the display unit, and the electromagnetic spring lock is pulled out of the display unit, so that the display unit is disassembled from the clamping and fixing structure, and the disassembly of the display unit is completed. At this time, because the inner edge of the frame of the clamping and fixing structure of the disassembly and assembly device is reserved with a corresponding guide rail, the display unit can slide along the guide rail into the installation position of the steel structure, and the corresponding lock on the display unit cooperates with the locking mechanism of the steel structure to complete the installation of the display unit on the steel structure.

[0106] like Figure 2 and Figure 3 The positioning device 30 is used to provide positioning for the transmission device 10 and the disassembly and assembly device 20, and includes: a transmission device positioning module and an unlocking mechanism positioning module 32. Among them:

[0107] The transmission device positioning module is installed on the transmission device 10 , and includes a first pressure sensor 311 , an angle sensor 312 , and a second pressure sensor 313 . Among them, the first pressure sensor 311 is installed on the overhead crane 1111, and is used to obtain the displacement information on the X-axis and feed it back to the control device 50 when the small wheel of the overhead crane 1111 is pressed on the corresponding position on the transverse guide rail; the angle sensor 312 is installed at the rotating shaft 11152 of the cantilever device 1115, and is used to obtain the rotation angle of the cantilever rod 11151, and feed back the rotation angle information to the control device 50, and the control device 50 calculates the height information of the cable outlet of the cable outlet module at the end of the cantilever rod 11151 from the splicing display device according to the rotation angle information, and obtains the displacement information on the Z axis; the second pressure sensor 313 is installed at the cable rail 121 and the meshing small wheel, and is used to obtain the position information of the meshing small wheel on the cable rail, and feeds back the position information to the control device 50, and the control device calculates the position information of the detection device 40 in the longitudinal direction of the screen according to the position information, and obtains the position information of the Y axis. By obtaining the relevant information of the first pressure sensor 311, the angle sensor 312 and the second pressure sensor 313, the specific position information such as the position of the detection device and the displacement distance can be detected during the operation of the transmission device, and the position information can be fed back to the control device in time so that the control device can make control instructions in time according to this information to improve the positioning accuracy.

[0108] The unlocking mechanism positioning module 32 is installed on the unlocking mechanism 23 of the disassembly and assembly device 20, and is used for the precise positioning of the unlocking mechanism 23, specifically, to precisely position the unlocking pin 231 of the unlocking mechanism, so that the unlocking pin 231 can be accurately inserted into the unlocking hole. The entire positioning process of the unlocking mechanism positioning module 32 is divided into three stages: the first stage is that the transmission device 10 transports the disassembly and assembly device 20 to the disassembly and assembly display unit (faulty display unit) or the position of the display unit to be installed, so as to achieve a rough positioning of the disassembly and assembly device and the corresponding display unit object. The second stage is that after the adsorption device is adsorbed on the splicing display device, the detection device scans the unlocking hole of the disassembly and assembly display unit to obtain the image information of the unlocking hole. The third stage is that the detection device calculates the error between the unlocking pin and the unlocking hole based on the acquired unlocking hole image, and the unlocking mechanism positioning module corrects the position of the unlocking pin according to the error information, and then enables the unlocking pin to be accurately inserted into the unlocking hole. Thereby, accurate positioning is provided for the subsequent disassembly of the faulty display unit and the installation of the replacement display unit.

[0109] When installing the display unit, the positioning is the same as the first and second stages of the positioning process for disassembling the display unit, and the main difference lies in the third stage. The positioning process of the unlocking mechanism positioning module 32 in the third stage is to obtain and correct the image of the locking mechanism of the steel structure, including: obtaining the image of the locking mechanism, calculating the error between the locking mechanism and the unlocking hole of the display unit, and the unlocking mechanism positioning module corrects the position of the locking mechanism according to the error information, so that the locking mechanism matches the unlocking hole of the display unit, thereby providing accurate positioning for the subsequent replacement of the display unit.

[0110] The scanning method of the detection device is to scan the screen line by line through the transmission device. The line spacing can be divided according to the size of the display unit module. The scanning process should have a round-trip feature, that is, considering the scanning path when the device returns, the round-trip path is combined into the overall scanning range of the device.

[0111] like Figure 1 and Fig.12 As shown. The detection device 40 is installed on the disassembly and assembly device 20, and the specific installation position is the center of the X-shaped telescopic device of the adsorption device. It is used to collect and obtain the image information of the display unit of the spliced ​​display device, identify and calculate and process the image information, and obtain the detection result of the display unit quality. The detection device 40 includes an information collection device 41 and an information processing device 42. The information collection device 41 is used to collect and obtain the image information of the display unit according to the control instruction of the control device 50, and transmit it to the information processing device 42; the information processing device 42 is used to process the display unit image information collected by the information collection device 41, obtain the detection result of the display unit image quality, and feed the detection result back to the control device 50.

[0112] The information collection device 41 includes a light source 411, a camera 412, and a sending card 413. The light source 411 uses a built-in LED light source to illuminate the camera 412.

[0113] The camera 412 is used to obtain image information of the display unit by lighting and photographing with a built-in LED light source, and to send the photographed image information to the information processing device 42 via the sending card 412 .

[0114] The information processing device 42 includes a receiving card 421 and a computing module 422, and the receiving card 421 is connected to the computing module 422. The receiving card 421 is used to receive the image information of the display unit sent by the sending card 413 of the information acquisition device 41, and send it to the computing module 421; the computing module 421 is used to identify and calculate the image information according to the received image information, detect and compare the quality information of the display unit, and confirm whether there is a detection result of a fault such as a dead light, a bright spot, a caterpillar, etc. of the display unit. The receiving card 421 is also used to feed back the detection result to the control device 50.

[0115] The detection device is based on machine vision technology and is divided into four processes: image information acquisition, image preprocessing, image recognition, and information feedback. The image information acquisition process is to capture the image information of the display unit surface through a camera, and the natural environment will be isolated to a certain extent during the shooting process; the image preprocessing process is to perform noise reduction and other processing on the captured image photos; the image recognition process is to perform image recognition on the image preprocessed by an image recognition method, and the recognition may include screen fault information, location information, temperature and other information; the information feedback process is to feed back the recognition results to the control device after the image recognition is completed for the next maintenance work. Among them, the image recognition method can adopt the existing image recognition method, and the present invention will not be described in detail here.

[0116] The scanning method of the detection device is to scan the screen line by line through the transmission device. The line spacing can be divided according to the size of the display unit module. The scanning process should have a round-trip feature, that is, considering the scanning path when the device returns, the round-trip path is combined into the overall scanning range of the device.

[0117] The control device 50 is respectively connected to the transmission device 10, the disassembly device 20, the positioning device 30, and the detection device 40 for communication, and sends control signals to the transmission device 10, the disassembly device 20, the positioning device 30, and the detection device 40 according to the detection results of the detection device.

[0118] In one embodiment, Figure 1 As shown, the splicing display device automatic maintenance system also includes a posture stabilizing device 60, which is installed on the disassembling device 20 and stably engaged with the cable rail 121. It is used to perform posture stabilizing operations for the detection device 40 and the disassembling device 20 during the operation of the transmission device to eliminate the error caused by the center of gravity offset of the detection device 40 and the disassembling device 20 when moving.

[0119] The present invention provides an automated maintenance system for a spliced ​​display device. When actually maintaining the spliced ​​display device, the control device sends a control instruction to the transmission device to control the lifting of a plurality of lifting arms installed on the periphery of the overhead crane, and lifts the cantilever device to a certain height, so that the disassembly and assembly device pulled by the cantilever device is higher than the spliced ​​display device, and the cantilever rod of the cantilever device tilts forward, so that the disassembly and assembly device moves from the rear of the spliced ​​display device to the front of the spliced ​​display device. At this time, the overhead crane controls the cable rail in the cable rail storage box to continuously lengthen according to the control instruction of the control device, so that the disassembly and assembly device engaged in the cable rail continuously descends due to the continuous lengthening of the cable rail. When the cable rail descends to the lower edge of the screen body, the traction device installed at the end of the cable rail cooperates with the clamping structure reserved at the bottom of the steel structure, thereby straightening the cable rail. The control device sends a control instruction to the detection device, so that the information collection device of the detection device collects and obtains the image information of the splicing display device according to the preset splicing display device maintenance plan, and transmits it to the information processing device; the information processing device processes the splicing display device image information collected by the information collection device, obtains the detection result of the splicing display device image quality, and feeds back the detection result to the control device, and with the cooperation of the transmission device, the detection device moves horizontally or vertically. When the detection result shows that a certain display unit is faulty, the unlocking mechanism positioning module of the positioning device is used to accurately position the unlocking mechanism installed in the disassembly and assembly device. After the unlocking pin is positioned by the positioning device, the telescopic structure extends outward according to the instruction of the control device, so that the unlocking pin is inserted into the corresponding unlocking hole, and the display unit can be unlocked from the locking mechanism of the steel structure. At this time, the display unit is slowly pulled out by the force of the unlocking pin and the unlocking hole. Because the inner edge of the frame of the clamping and fixing structure of the disassembly and assembly device is reserved with a corresponding guide rail, the display unit can be pulled out in the Z-axis direction with less resistance, so the cooperation force of the unlocking pin and the unlocking hole can pull the display unit out. After the display unit is pulled out onto the disassembly and assembly device, the electromagnetic spring lock in the disassembly and assembly device is inserted into the reserved hole on the square steel of the display unit. When the electromagnetic spring lock is inserted into the reserved hole of the square steel, the electromagnetic spring lock is subjected to the electromagnetic adsorption force during the insertion process, and its card plate will shrink to a position smaller than the aperture. After passing through the reserved hole, the electromagnetic coil is powered off, the magnetism disappears, and the card plate is stretched outside the aperture by the spring elastic force. Half of the protruding part of the card plate will bear the square steel surface of the display unit, lift the entire display unit or position the display unit, thereby fixing the display unit on the clamping and fixing structure, and completing the fixation of the display unit.At this time, the permanent magnet of the adsorption device gently contacts the surface of the display unit. Due to the weak magnetism of the permanent magnet, the contact force between the permanent magnet and the surface of the spliced ​​display device in the display unit is not very large, so that the display unit slowly contacts the adsorption device, which acts as a buffer for the strong adsorption of the electromagnet and will not damage the spliced ​​display device in the display unit. After the permanent magnet contacts the surface of the display unit, the electromagnet is energized to adsorb the display unit, so that the adsorption device and the display unit cooperate with each other. After the cooperation is completed, the display unit is fixedly adsorbed on the adsorption device of the disassembly and assembly device. At this time, the control device controls the rotating motor to drive the unlocking pin to rotate counterclockwise, and controls the telescopic structure to retract inward to pull the unlocking pin out of the unlocking hole. At this time, the entire disassembly process of the display unit is completed. At this time, the control device controls the transmission device to move and transfer the disassembled display unit to the display unit replacement library.

[0120] The disassembly and assembly device grabs the replacement display unit from the display unit replacement library, and when the electromagnetic spring lock of the clamping and positioning structure is inserted into the reserved hole of the square steel of the display unit, the electromagnetic spring lock is subjected to the electromagnetic adsorption force during the insertion process, and its card plate will shrink to a position smaller than the aperture. After passing through the reserved hole, the electromagnetic coil is powered off, the magnetism disappears, and the card plate is stretched to the outside of the aperture by the spring elastic force, so that the display unit is fixed on the clamping and fixing structure, and the display unit is fixed. The adsorption device adsorbs the display unit that needs to be replaced and installed, and is moved to the installation position of the positioned steel structure by the conveying device. After reaching the installation position, when the electromagnetic coil of the electromagnetic spring lock is energized, the electromagnetic coil generates a strong electromagnetic adsorption force, so that the card plate is contracted to the overall size of the electromagnetic spring lock by the electromagnetic suction force, so that the electromagnetic spring lock is separated from the square steel reserved hole of the display unit, and the electromagnetic spring lock is pulled out of the display unit, so that the display unit is disassembled from the clamping and fixing structure, and the disassembly of the display unit is completed. At this time, since the inner edge of the frame of the clamping and fixing structure of the disassembly and assembly device is equipped with a corresponding guide rail, the display unit can slide into the installation position of the steel structure along the guide rail, and the corresponding lock on the display unit cooperates with the locking mechanism of the steel structure to complete the installation of the display unit on the steel structure.

[0121] The present invention provides an automated maintenance system for a spliced ​​display device. When the spliced ​​display device is actually installed as a whole, the installation can be performed according to a preset installation sequence. For example, the display unit at the lower right corner of the spliced ​​display device is installed first, and then the installation path can be installed horizontally or vertically, and the subsequent display units are installed, and finally the upper left display unit is installed.

[0122] When installing a single display unit, the disassembly and assembly device grabs the display unit to be installed from the display unit installation library, and when the electromagnetic spring lock of the clamping and positioning structure is inserted into the reserved hole of the square steel of the display unit, the electromagnetic spring lock is subjected to the electromagnetic adsorption force during the insertion process, and its card plate will shrink to a position smaller than the aperture. After passing through the reserved hole, the electromagnetic coil is powered off, the magnetism disappears, and the card plate is stretched to the outside of the aperture by the spring elastic force, so that the display unit is fixed on the clamping and fixing structure, and the display unit is fixed. The adsorption device adsorbs the display unit that needs to be replaced and installed, and is moved to the positioned steel structure installation position by the conveying device. After reaching the installation position, when the electromagnetic coil of the electromagnetic spring lock is energized, the electromagnetic coil generates a strong electromagnetic adsorption force, so that the card plate is contracted to the overall size of the electromagnetic spring lock by the electromagnetic suction force, so that the electromagnetic spring lock is separated from the square steel reserved hole of the display unit, and the electromagnetic spring lock is pulled out of the display unit, so that the display unit is disassembled from the clamping and fixing structure, and the disassembly of the display unit is completed. At this time, since the inner edge of the frame of the clamping and fixing structure of the disassembly and assembly device is reserved with a corresponding guide rail, the display unit can slide into the installation position of the steel structure along the guide rail, and the corresponding lock on the display unit cooperates with the locking mechanism of the steel structure to complete the installation of a single display unit on the steel structure. After that, the installation of the remaining display units is completed according to the preset installation sequence and the installation process of the above single LED.
