Description

Technical Field

[0001] This utility model relates to the field of front maintenance technology for display modules, and in particular to a front maintenance device for LEDs. Background Technology

[0002] In the field of LED front-maintenance display modules, front maintenance of LED display modules is a crucial step in ensuring the long-term stable operation of the equipment. Current mainstream front maintenance solutions for LED display modules generally involve using an Allen wrench to penetrate the front of the module and then rotating the locking mechanism to remove and install the LED display module. This requires pre-drilling a tool access hole in the LED display module body. During maintenance, the Allen wrench is inserted through this hole to rotate the locking mechanism on the back of the display module, thus detaching the display module from the display housing.

[0003] However, the tool access holes on the front of the display module need to penetrate the surface structure of the display module, which not only damages the integrity of the display module's appearance, but also easily forms stress concentration areas around the holes. During long-term use or maintenance, the LED beads around the holes are easily damaged by external impacts, vibrations, or improper operation, or the solder joints of the beads may fall off due to stress transmission, directly affecting the display effect and the lifespan of the module. The maintenance process relies heavily on special tools such as hexagonal wrenches, and the operation requires precise alignment of the holes and latches. The process is cumbersome and requires a high level of skill from maintenance personnel, resulting in low maintenance efficiency. The presence of the tool penetration holes can also become a channel for the intrusion of dust, moisture, and other impurities, increasing the risk of moisture and short circuits in the internal circuitry of the display module, further reducing the reliability of the equipment.

[0004] Therefore, there is an urgent need to design a technical solution that can provide convenient maintenance, avoid damage to LED beads, and improve the overall reliability of LED display devices. Utility Model Content

[0005] The purpose of this utility model is to provide an LED front maintenance device to solve the problems existing in the prior art, which can provide maintenance convenience, avoid damage to LED beads, and improve the overall reliability of LED display devices.

The receiving part has one end connected to the inside of the LED display module and the other end provided with a receiving interface. The end of the insertion part away from the LED housing can be inserted into the insertion part through the receiving interface; and A magnetic suction part is movably disposed within the receiving part, one end of which is connected to the end of the receiving part away from the receiving interface via an elastic element; When the magnetic suction part is in the first position, it can be fixedly engaged with the limiting groove to fix and limit the insertion part. Under the action of external magnetic attraction, the magnetic suction part can squeeze the elastic member and move to the second position away from the receiving interface. When the magnetic suction part is in the second position, it disengages from the limiting groove to release the limitation on the insertion part.

[0007] Preferably, a positioning plate is fixedly provided at the end of the plug-in portion away from the limiting groove, and the positioning plate is fixedly attached to the LED box.

[0008] Preferably, a pin clamping plate is fixedly provided on the LED housing, and the positioning plate is fixedly clamped between the pin clamping plate and the LED housing.

[0011] Preferably, the cavity includes a constant diameter section and a constricted section. One end of the constant diameter section is fixedly connected to the cavity cover, and the other end is connected to the constricted section. The inner diameter of the constricted section gradually decreases from the constant diameter section to the receiving interface, and the inner diameter of the constant diameter section is the same as the maximum inner diameter of the constricted section. When the magnetic suction part is located inside the constricted section, it is in the first position; when the magnetic suction part is located in the constant diameter section, it is in the second position.

[0012] Preferably, the magnetic suction part includes a steel ball sleeve and a steel ball. The steel ball sleeve is coaxially arranged with the receiving interface, and a through hole is opened at one end of the steel ball sleeve near the receiving interface. The end of the steel ball sleeve away from the receiving interface is connected to the end of the cavity near the cavity cover through the elastic element. The steel ball is movably disposed on the side wall of the steel ball sleeve. The outer side wall of the steel ball is rolledly connected to the inner side wall of the cavity. When the magnetic suction part is in the first position, the inner side wall of the steel ball can be fixedly engaged with the limiting groove.

[0013] Preferably, the sidewall of the steel ball sleeve has two through-hole cavities symmetrically arranged, each cavity containing a steel ball. The outer sidewall of the steel ball is located outside the steel ball sleeve, and the inner sidewall of the steel ball is located inside the steel ball sleeve. The sidewall of the insertion part has two limiting grooves symmetrically arranged, and the inner sidewall of the steel ball can engage with the adjacent limiting groove.

[0014] Preferably, it also includes a magnetic vacuum chuck, which can fix and adsorb the LED display module on the side away from the LED housing, and the magnetic force of the magnetic vacuum chuck can adsorb the magnetic part to move to the second position.

[0015] This utility model also provides a working method based on the aforementioned LED front maintenance device, including the following steps: During installation, the LED display module is adsorbed by a magnetic vacuum suction cup. The magnetic suction part is in the second position, and the LED display module is installed by docking with the LED cabinet. One end of the plug is inserted into the receiving part. The magnetic force of the magnetic vacuum suction cup is removed. Under the restoring force of the elastic element, the magnetic suction part is driven to move to the first position, so that the steel ball is engaged with the limiting groove. During disassembly, the LED display module is adsorbed by a magnetic vacuum chuck. The magnetic force is used to move the magnetic suction part to the second position, releasing the magnetic suction part from the insertion part. The magnetic vacuum chuck then moves the LED display module away from the LED housing, completing the disassembly of the LED display module.

[0016] The present invention achieves the following technical advantages over the prior art: When no external operation is required, this invention uses the mechanical cooperation of the plug-in part, magnetic part, and elastic element to stably lock the LED display module, preventing it from loosening. Disassembly only requires the use of a magnetic vacuum suction cup to attract the LED display module while simultaneously using magnetic force to pull the magnetic part to a second position, releasing the magnetic part's restriction on the plug-in part, thus separating the LED display module from the LED housing. No complex tools are needed, making operation simple and improving maintenance efficiency. The hole-free module design and magnetic disassembly / removal method completely avoid the problems of LED chip impact and stress damage caused by traditional tool-operated through-hole operations, improving module lifespan and display reliability. It eliminates the need for specialized tools such as Allen wrenches, simplifying the maintenance process, lowering the operational threshold for maintenance personnel, and improving maintenance efficiency. The synergistic effect of magnetism and vacuum adsorption ensures precise positioning during module disassembly and assembly, avoiding module misalignment or improper installation that may occur with traditional locking and rotating operations.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The purpose of this utility model is to provide an LED front maintenance device to solve the problems existing in the prior art, which can provide maintenance convenience, avoid damage to LED beads, and improve the overall reliability of LED display devices.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] LED, or Light Emitting Diode, is an electroluminescent semiconductor electronic device. Existing front maintenance solutions for LED display modules generally involve using an Allen wrench to penetrate the front of the module and then rotating the locking mechanism on the back to remove or install the LED display module. This requires pre-drilling a tool access hole in the LED display module body. During maintenance, the Allen wrench is inserted through this hole to rotate the locking mechanism on the back of the display module to achieve assembly and disassembly. However, the tool access hole on the front of the display module needs to penetrate the surface structure, which not only damages the integrity of the display module's appearance but also easily creates stress concentration areas around the hole. Over time, during use or maintenance, external impacts, vibrations, or improper operation can easily cause damage to the LED beads around the hole, or stress conduction can cause the LED bead solder joints to detach, directly affecting the display effect and the module's lifespan. To solve this problem, this utility model provides an LED front maintenance device, referenced... Figure 1As shown, the device includes a magnetic vacuum suction cup 12, a plug-in part 3, a receiving part, and a magnetic suction part. One end of the plug-in part 3 is fixedly connected to the LED housing 1, and a limiting groove is formed on the side wall of the other end. One end of the receiving part is connected to the inside of the LED display module 2, and the other end is provided with a receiving interface. The end of the plug-in part 3 away from the LED housing 1 can be inserted into the plug-in part 3 through the receiving interface. The magnetic suction part is movably disposed in the receiving part, and one end of it is connected to the end of the receiving part away from the receiving interface through an elastic member 11. When the magnetic suction part is in the first position, it can... The limiting groove is fixed and snapped to fix and limit the insertion part 3. Under the external magnetic attraction, the magnetic part can squeeze the elastic member 11 and move to the second position away from the receiving interface. When the magnetic part is in the second position, it disengages from the limiting groove to release the limitation on the insertion part 3. The magnetic vacuum chuck 12 can fix and adsorb the LED display module 2 away from the LED cabinet 1, and the magnetic force of the magnetic vacuum chuck 12 can adsorb the magnetic part to move to the second position. In this embodiment, the elastic member 11 is a spring.

[0024] When no external operation is required, this invention securely holds the LED display module 2 in place through the mechanical cooperation of the insertion part 3, the magnetic part, and the elastic element 11, preventing loosening. Disassembly only requires the use of the magnetic vacuum suction cup 12 to attract the LED display module 2 while simultaneously using magnetic force to attract the magnetic part to the second position, releasing the magnetic part's restriction on the insertion part 3, thus separating the LED display module 2 from the LED housing 1. No complex tools are needed, making operation simple and improving maintenance efficiency. The hole-free module design and magnetic disassembly / assembly method completely avoid the problems of LED bead impact and stress damage caused by traditional tool-operated through-hole operations, improving module lifespan and display reliability. It eliminates the need for specialized tools such as hexagonal sockets, simplifying the maintenance process, lowering the operational threshold for maintenance personnel, and improving maintenance efficiency. The synergistic effect of magnetism and vacuum adsorption ensures precise positioning during module disassembly and assembly, avoiding module misalignment or improper installation that may occur with traditional locking and rotation operations.

[0025] In one embodiment, to improve the stability of the connection, a positioning plate is fixedly provided at the end of the plug-in portion 3 away from the limiting groove. The positioning plate is fixedly attached to the LED housing 1. Alternatively, the plug-in portion 3 and the positioning plate are integrally formed, making the whole into a pin structure with a T-shaped cross-section. A pin clamping plate 4 is fixedly provided on the LED housing 1 by screws or screws 8. The pin clamping plate 4 is attached and fixed to the side of the positioning plate away from the LED housing 1, so that the positioning plate is fixedly clamped between the pin clamping plate 4 and the LED housing 1, improving the connection between the plug-in portion 3 and the LED housing 1 and preventing loosening.

[0026] In one embodiment, the receiving part includes a cavity 5 and a cavity cover 6. One end of the cavity cover 6 is fixedly connected to the LED display module 2, and the other end is fixedly connected to the cavity 5. The cavity 5 has a receiving interface at the end away from the cavity cover 6. The cavity cover 6 can achieve sealing and protection of the cavity 5 and provide a certain support force for the cavity 5. In order to further improve the connection between the cavity 5 and the LED display module 2, in one embodiment, a cavity pressure plate 7 is fixedly connected to the LED display module 2 by screws 8. One end of the cavity pressure plate 7 is fixedly abutted against the outer wall of the cavity 5. When one cavity pressure plate 7 is provided, the cavity pressure plate 7 has a central hole, and the cavity 5 passes through the central hole and is fixed by the cavity pressure plate 7 and screws 8. When two or more cavity pressure plates 7 are provided, the multiple cavity pressure plates 7 are arranged around the outside of the cavity 5, and the side of one end of the cavity pressure plate 7 is fixedly abutted against the adjacent outer wall of the cavity 5 to fix the cavity 5.

[0027] In one embodiment, the magnetic suction part includes a steel ball sleeve 10 and a steel ball 9. The steel ball sleeve 10 is coaxially arranged with the receiving interface, and a through hole is opened at the end of the steel ball sleeve 10 near the receiving interface. The end of the steel ball sleeve 10 away from the receiving interface is connected to the end of the cavity 5 near the cavity cover 6 through an elastic member 11. The steel ball 9 is movably disposed on the side wall of the steel ball sleeve 10. The outer side wall of the steel ball 9 is rolledly connected to the inner side wall of the cavity 5. In order to make the limiting effect of the steel ball 9 better, two through-hole receiving cavities are symmetrically opened on the side wall of the steel ball sleeve 10. Each receiving cavity is provided with a steel ball 9. The outer side wall of the steel ball 9 is located outside the steel ball sleeve 10, and the inner side wall of the steel ball 9 is located inside the steel ball sleeve 10. Two limiting grooves are symmetrically opened on the side wall of the insertion part 3. The inner side wall of the steel ball 9 can be engaged with the adjacent limiting groove. The elastic member 11 cooperates with the steel ball 9 to provide pre-tightening force when there is no external magnetic attraction, so that the LED display module 2 is clamped and fixed.

[0028] To prevent the magnetic attraction structure from tilting during reciprocating movement under magnetic force, in one embodiment, the cavity 5 includes a constant-diameter section and a constricted section. One end of the constant-diameter section is fixedly connected to the cavity cover 6, and the other end is connected to the constricted section. The inner diameter of the constricted section gradually decreases from the constant-diameter section to the receiving interface, and the inner diameter of the constant-diameter section is the same as the maximum inner diameter of the constricted section. When the magnetic attraction part is located inside the constricted section, it is in the first position. At this time, the outer wall of the steel ball 9 abuts against the inner wall of the constricted section, and the inner wall of the steel ball 9 engages with the adjacent limiting groove, so that the insertion part 3 is fixed. When a magnet or electromagnet is provided externally... When the vacuum suction cup 12 is adsorbed onto the LED display module 2, the steel ball 9 moves synchronously toward the LED display module 2 under the action of magnetic force, driving the steel ball sleeve 10. During this process, the inner wall of the cavity 5 provides guidance for the steel ball 9. When the steel ball 9 moves to the equal diameter section, it is in the second position, and the locking effect of the inner side of the steel ball 9 on the limiting groove is released. At this time, the insertion part 3 can be pulled out from the receiving part, thereby allowing the LED display module 2 to separate from the LED housing 1. The steel ball 9 is always limited and guided by the inner wall of the cavity 5 during the movement, so it will not deviate. The magnetic vacuum chuck 12 is connected to lifting equipment, etc. The magnetic vacuum chuck 12 is formed by setting a magnet or electromagnet at the center of the vacuum chuck. Since the magnet or electromagnet is located at the center, the magnetic suction part is also located at the center of the LED display module 2. Therefore, when the magnetic vacuum chuck 12 adsorbs the outside of the LED display module 2, the magnet or electromagnet and the magnetic suction part are arranged coaxially, so that during the adsorption of the steel ball 9, the steel ball 9 moves along the axis of the magnetic suction part without deflection.

[0029] This invention uses a magnetic vacuum chuck 12 as the maintenance execution component, eliminating the need for any operation holes in the LED display module 2. The vacuum adsorption force and magnetic force of the chuck work together to achieve frontal adsorption and positioning of the LED display module 2. The LED display module 2 eliminates the tool operation holes required for traditional maintenance. The precise docking of the magnetic front maintenance mechanism with the magnetic coupling structure on the back of the module completes the installation, fixing, and disassembly of the module, avoiding the risk of damage to the internal LED chips and circuitry caused by hole machining.

[0030] This utility model also provides a working method based on an LED front maintenance device, including the following steps: During installation, the LED display module 2 is attracted by the magnetic vacuum chuck 12. Using magnetic force, the magnetic suction part is positioned in the second position, allowing the LED display module 2 to be aligned with the LED housing 1. One end of the insertion part 3 is inserted into the receiving part. The magnetic force of the magnetic vacuum chuck 12 is then released, and the spring is in a pre-tensioned state. Under the restoring force of the spring, the magnetic suction part is moved to the first position, pushing the steel ball 9 back into place. This causes the steel ball 9 to engage with the limiting groove. Through the cooperation of the steel ball 9 and the pins of the LED housing 1, the LED display module 2 is firmly secured to the LED housing 1, achieving anti-loosening fixation. The magnetic force of the magnetic vacuum chuck 12 and the magnetic force of the magnetic suction part on the back of the LED display module 2 guide and position it, ensuring precise alignment between the LED display module 2 and the preset installation position of the LED housing 1, completing tool-free installation.

[0031] During disassembly, the LED display module 2 is attracted by the magnetic vacuum chuck 12. The magnetic force is used to move the magnetic suction part to the second position, releasing the magnetic suction part from the insertion part 3. The magnetic vacuum chuck 12 drives the LED display module 2 to move away from the LED housing 1. The magnetic vacuum chuck 12 enhances the attraction force on the front of the LED display module 2. At the same time, the magnetic force is used to unlock the magnetic suction part on the back of the LED display module 2. The steel ball 9 overcomes the spring force under the action of magnetic attraction, and moves the steel ball sleeve 10 to release the clamping limit on the LED display module 2. This overcomes the fixing force between the LED display module 2 and the LED housing 1, and realizes the convenient disassembly of the LED display module 2 from the front. The whole process does not require the use of tools such as Allen wrenches, and there is no contact or stress damage to the LED beads.

[0032] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
