Description

Technical Field

[0001] This invention belongs to the field of display device technology, specifically a display module disassembly and assembly tool and its usage method. Background Technology

[0002] Large-scale displays (especially LED video walls) are widely used in advertising media, stage performances, conferences and exhibitions, traffic control, and security monitoring. These displays typically consist of dozens or even hundreds of independent display modules spliced ​​together to achieve a large-size, high-resolution overall display effect. During long-term continuous operation, individual display modules inevitably malfunction due to factors such as heat dissipation, power fluctuations, and component aging, resulting in issues such as missing pixels, uneven brightness, or signal abnormalities. To ensure the normal display of the entire screen, faulty modules must be repaired or replaced promptly.

[0003] In existing technologies, disassembling display modules typically relies on general-purpose tools such as pry bars and suction cups, or relatively simple specialized tools. However, using these tools for disassembly often results in inconvenience and low efficiency. For example, suction cups or pry bars remove the module using adsorption or leverage principles; however, suction cups are prone to slipping when surface adhesion is insufficient, and repeated lifting can scratch the module coating. Pry bars need to be inserted into extremely narrow module gaps, requiring precise control of the operating angle and force; slight carelessness can damage the module edges or bump adjacent modules, making it difficult to meet the requirements for efficient and non-destructive disassembly. For example, some specialized chuck disassembly tools typically include a pair of openable chucks. However, the opening and closing function uses complex transmission mechanisms such as multi-links, gears, and racks, resulting in a large number of parts and complex assembly processes. This not only increases manufacturing costs but also raises the failure rate. At the same time, some existing tools have unreasonable force-applying structures, often requiring the assistance of both hands to open the chucks to the effective working position, which is time-consuming and laborious. Furthermore, the lack of effective stroke limits means that the operator cannot perceive whether the chucks are fully open, and excessive pressure can easily lead to tool deformation or damage to the module slots.

[0004] Therefore, there is an urgent need in the existing technology for a special tool for disassembling display modules that is structurally simple, moves smoothly, has clear stroke feedback, and is easy to apply force, so as to reduce the difficulty of operation, improve the disassembly efficiency, and effectively avoid secondary damage to the display module. Summary of the Invention

[0005] This application provides a display module disassembly and assembly tool and its usage method, aiming to solve the technical problems in the prior art where disassembling display modules is inconvenient, inefficient, and prone to causing module damage.

[0006] The first objective of this invention is to provide a display module assembly / disassembly tool, comprising a first structural component and a second structural component:

[0007] The first structural component includes a hand-held part, a mounting part, and a contact part connected in sequence. The mounting part has two longitudinally extending mounting grooves symmetrically arranged inside.

[0008] The second structural component includes a pressing ring connected in sequence, sliding arms disposed at two free ends of the pressing ring, and two claws respectively connected to the ends of the corresponding sliding arms; the sliding arms are slidably inserted into the corresponding mounting grooves along the longitudinal direction, the claws are located below the contact portion, and an elastic reset element is provided between the sliding arms and the cavity wall of the mounting groove; the two sliding arms are arranged outwardly toward the contact portion.

[0009] The handle is located inside the pressing ring. The part on the pressing ring opposite to the handle is the pressing part. The pressing part and the handle can move relative to each other under the action of external force, so as to drive the two sliding arms to slide in the mounting groove and compress the elastic reset member, so that the two claws open and move away from each other. When the external force is removed, the elastic reset member pushes the sliding arms to reset, so that the two claws move closer to each other and retract.

[0010] Furthermore, each mounting slot includes a guide slot and a mounting cavity that are parallel and connected in the longitudinal direction, with the guide slot located outside the mounting cavity; the sliding arm is slidably inserted into the guide slot, and the elastic reset member is located in the mounting cavity and is compressed or reset as the sliding arm slides.

[0011] Furthermore, a limiting component is fixedly provided on the inner side of each sliding arm, and the limiting component is located in the corresponding mounting cavity; the elastic reset component is a spring, and its two ends abut against the limiting component and the bottom wall of the mounting cavity, respectively.

[0012] Furthermore, the guide groove has a lower opening at one end near the contact portion for the sliding arm to pass through, and the width of the lower opening is configured to limit the maximum opening angle of the pawl.

[0013] Furthermore, a first stroke end point and a second stroke end point are provided at intervals on the sliding arm near the pawl; each lower opening is formed by a first protrusion and a second protrusion arranged laterally opposite each other, and the width of the lower opening is greater than the thickness of the sliding arm.

[0014] When the sliding arm moves to the end of the first stroke and abuts against the first protrusion under the action of external force, the pawl is in a fully open state; when the sliding arm moves in the opposite direction to the end of the second stroke and abuts against the second protrusion under the action of the reset elastic element, the pawl is in a fully retracted state.

[0015] Furthermore, a limiting member is fixedly provided on the inner side of each sliding arm. The limiting member slides between the top wall of the mounting cavity and the first protrusion. When the limiting member abuts against the top of the mounting groove, the second stroke end point abuts against the second protrusion. When the limiting member abuts against the first protrusion, the first stroke end point abuts against the first protrusion.

[0016] Furthermore, the first protrusion includes a first arcuate surface facing downward, a first inclined surface above the first arcuate surface, and an abutting surface at the top of the first inclined surface. The inclination direction of the first inclined surface is consistent with the inclination direction of the sliding arm, and the inclination angle of the first inclined surface is greater than the inclination angle of the sliding arm. The abutting surface is used to abut against the limiting member.

[0017] Furthermore, all second structural components are integrally molded.

[0018] Furthermore, the second structural component is a sheet metal part.

[0019] Furthermore, an elastic buffer pad is provided on the working surface of the contact part.

[0020] The second objective of this invention is to provide a method for using a display module disassembly tool, comprising the following steps:

[0021] Remove the fasteners on both sides of the display module and disassemble the structure of the upper and lower parts of the display module;

[0022] Hold the disassembly tool, hook your fingers onto the handle of the first structural component, and press your palm against the pressing part of the second structural component. Apply external force to make the handle and pressing part move relative to each other until the limiting part abuts against the top wall of the mounting groove and the two claws open to their maximum distance.

[0023] Align the open claws with the slot on the upper part of the display module, release the external force on the first and second structural components, and under the elastic reset action of the elastic reset component, the two claws retract and engage in the slot.

[0024] Pulling the second structural component upwards separates the upper and lower parts of the display module.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] (1) The disassembly and assembly tool of this application causes the first structural component and the second structural component to move relative to each other by applying external force. By designing the sliding arm as an outward expansion structure facing the contact part, the opening and closing of the claw can be controlled by one hand. The operation is ergonomic. It can be opened by gripping and applied force, and automatically retracted by releasing. Compared with traditional tools, it simplifies the operation steps and improves the disassembly efficiency.

[0027] (2) The disassembly and assembly tool of this application provides automatic reset force by setting an elastic reset component between the sliding arm and the cavity wall of the mounting groove. Through the cooperation of the sliding arm, mounting groove, first stroke end point, second stroke end point, limit component and other structures, the precise control of the opening and closing stroke of the claw is realized, ensuring that the claw can be accurately opened to the predetermined width and reliably locked in the slot of the display module, avoiding the problem of incomplete clamping or excessive opening.

[0028] (3) The contact part of the disassembly and assembly tool of this application is provided with an elastic buffer pad layer, which plays a buffering and protective role when in contact with the display module, effectively avoiding scratches or pressure damage to the surface of the display module and ensuring the safety of the disassembly process.

Detailed Implementation

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0038] The following is in conjunction with the appendix Figure 1 To be continued Figure 6 The invention is described in detail with specific embodiments.

[0039] This application provides a display module disassembly tool, aiming to solve the problems of inconvenience, low efficiency, and easy damage to the module surface when disassembling snap-fit ​​display modules by hand or using general tools in the prior art. This tool allows for precise and complete separation of the snap-fit ​​and lifting of the display module with one hand. See reference. Figure 6 In typical application scenarios, a display screen is usually composed of multiple independent display modules 100 spliced ​​together and fixed by a mounting frame. Each display module 100 can be divided into an upper display module portion 102 and a lower display module portion 103, which are fixed by fasteners 104. The disassembly tool of the present invention is used to safely separate the upper display module portion 102 from the lower display module portion 103 after removing the fasteners 104.

[0040] See Figures 1 to 6 The overall structure of the display module disassembly tool of this application mainly includes a first structural component 10 and a second structural component 20 that cooperate with each other. These two structural components are coupled together by a sliding installation method, forming the main body of the disassembly tool. Specifically, the first structural component 10 includes a handle 11, a mounting part 12, and a contact part 13 connected in sequence. The handle 11 is designed with an ergonomic shape, such as... Figure 1 The closed ring shown facilitates stable hooking or gripping by the operator's fingers. The mounting portion 12, connecting the handheld portion 11 and the contact portion 13, serves as a guide and support for the movement of the second structural component 20. The contact portion 13, located at the distal end of the disassembly tool, has its working surface used to contact the surface of the display module 100 during disassembly, providing support and positioning. Two longitudinally extending mounting grooves 121 are symmetrically arranged within the mounting portion 12 of the first structural component 10. These two mounting grooves 121 form the basic structure for realizing the sliding function of the second structural component 20; their internal contours and dimensions are precisely designed to ensure smooth and stable sliding.

[0041] The second structural component 20 includes a pressing ring 21 connected in sequence, sliding arms 22 disposed at two free ends of the pressing ring 21, and two claws 23 respectively connected to the ends of the corresponding sliding arms 22. The pressing ring 21 constitutes the driving part of the second structural component 20, and the part on it opposite to the hand-held part 11 is defined as the pressing part 211, on which the operator's palm can apply pressure. Each sliding arm 22 is slidably inserted longitudinally into the corresponding mounting groove 121. The claws 23 are the actuating components that directly interact with the slots 101 of the display module 100. In terms of spatial layout, the claws 23 are located below the contact part 13, ensuring that when the contact part 13 abuts against the display module 100, the claws 23 can accurately align and extend into the slots 101. In order to achieve the automatic reset function, an elastic reset element 30 is provided between the sliding arm 22 and the cavity wall of the mounting groove 121; the two sliding arms 22 are arranged outward in the direction of the contact part 13, and the outward expansion design is the key geometric basis for realizing the opening action of the claw 23.

[0042] See Figure 1 and Figure 2 In a static or initial state, the elastic reset member 30 is in a naturally extended or slightly compressed state. Its elastic force pushes the sliding arm 22 towards the pressing ring 21. At this time, due to the outward expansion geometry of the sliding arm 22, the two claws 23 approach each other and are in a contracted state; see reference Figure 4 When the display module 100 needs to be disassembled, the operator holds the tool with one hand, hooks their fingers onto the handle 11 of the first structural component 10, and simultaneously presses their palm against the pressing part 211. By applying external force, the pressing part 211 and the handle 11 can move relative to each other (i.e., move closer to each other). This drives the pressing ring 21 to move the two sliding arms 22 in the mounting groove 121 toward the contact part 13, compressing the elastic reset member 30. During the sliding process, since the sliding arms 22 move along an outward trajectory, the lateral distance between the two claws 23 at their ends gradually increases, thus achieving the action of opening and moving away from each other. When the external force is removed, the elastic potential energy stored in the compressed elastic reset member 30 is released, pushing the sliding arms 22 to reset in the opposite direction, thereby causing the two claws 23 to move closer to each other and retract, returning to the initial state. This linkage mechanism makes the opening and closing action of the claws 23 responsive and automatic, improving the convenience of operation.

[0043] This application converts the linear pressing action of the user's palm into the opening and closing action of the claw 23 by the relative sliding of the first structural member 10 and the second structural member 20. Combined with the automatic reset function of the elastic reset member 30, it realizes one-handed operation and solves the cumbersome problem of two-handed operation or the need for auxiliary tools in the prior art. It has the technical effects of simple structure, intuitive operation, labor-saving and high efficiency.

[0044] For further details, please refer to [link / reference]. Figure 2 and Figure 4 To ensure smoother and more precise movement of the sliding arm 22 and to effectively accommodate the elastic reset member 30, each mounting groove 121 includes a longitudinally parallel and interconnected guide groove 1211 and a mounting cavity 1212. The guide groove 1211 is located outside the mounting cavity 1212. The sliding arm 22 is slidably inserted into the guide groove 1211, and the elastic reset member 30 is located within the mounting cavity 1212, and is compressed or reset as the sliding arm 22 slides. It should be noted that the sliding arm 22 in this application is elastic, and because the two sliding arms 22 are designed to expand outwards, the sliding of the sliding arm 22 is not limited by the shape inside the guide groove 1211, but by the openings at both ends. Specifically, in order to provide a stable and reliable support point for the elastic reset member 30 and further constrain the movement of the sliding arm 22, a limiting member 40 is fixedly provided on the inner side of each sliding arm 22. The limiting member 40 is a component that limits the stroke range of the sliding arm 22. The limiting member 40 is located in the corresponding mounting cavity 1212 and moves together with the sliding arm 22. The elastic reset member 30 is a spring or elastic rubber block, etc., used to provide restoring force. When the external force is removed, its stored elastic potential energy is released, pushing the second structural member 20 to reset. The two ends of the elastic reset member 30 abut against the limiting member 40 and the bottom wall of the mounting cavity 1212, respectively. The guide groove 1211 has an upper opening 1213 and a lower opening 1214 at its two ends respectively: the upper opening 1213 is located at the end away from the contact part 13, and its width is much greater than the thickness of the sliding arm 22 to provide space for the sliding arm 22 to move and shift; the lower opening 1214 is located at the end close to the contact part 13, through which the sliding arm 22 passes, and the width of the lower opening 1214 is configured to limit the maximum opening angle of the pawl 23, that is, when the sliding arm 22 slides down or up, part of its structure will abut against the edge of the lower opening 1214, thereby preventing it from continuing to move outward.

[0045] Furthermore, referring to Figure 2, in this application, the two free ends of the pressing ring 21 of the second structural member 20 are designed with constricted ends. In other words, the pressing ring 21 has an annular shape with a central angle greater than 180°. The distance between the two free ends is less than the maximum outer diameter of the pressing ring 21, and the connection between the free ends and the sliding arm 22 is transitioned by an arc structure 223. The protrusion of the arc structure 223 faces the axis of the tool, that is, towards the inward side. When pressure is applied to the pressing ring 21, the arc structure 223 pushes against the head end of the sliding arm 22, generating a component force towards the elastic reset member 30, thereby making the sliding arm 22 a lever to facilitate the opening of the pawl 23. Additionally, refer to... Figure 1 , Figure 2 , Figure 5In the static or initial state, the arc structure 223 is located above the upper opening 1213. When a force is applied to make the sliding arm 22 slide outward, the arc structure 223 enters the guide groove 1211 from the upper opening 1213. Therefore, the opening area of ​​the upper opening of the guide groove 1211 is large, which is conducive to making way.

[0046] In some specific implementations, see [reference] Figure 4 and Figure 5 To achieve precise control over the opening and closing stroke of the chuck 23, a first stroke endpoint 221 and a second stroke endpoint 222 are provided at intervals on the sliding arm 22 near the chuck 23; these two stroke endpoints can be specific steps, protrusions, or marks on the sliding arm 22. Correspondingly, each lower opening 1214 is formed by a first protrusion 14 and a second protrusion 15 arranged laterally opposite each other, and the width of the lower opening 1214 is greater than the thickness of the sliding arm 22, while also limiting the movement of the sliding arm 22.

[0047] When the operator applies external force to move the sliding arm 22 downwards until its first stroke endpoint 221 abuts against the first protrusion 14, the outward stroke of the sliding arm 22 reaches its maximum, at which point the chuck is fully open. Conversely, when the external force is removed, the sliding arm 22 moves in the opposite direction under the action of the elastic reset member 30 until its second stroke endpoint 222 abuts against the second protrusion 15, at which point the upward stroke of the sliding arm 22 reaches its endpoint, and the chuck 23 is fully retracted. This precise alignment of the stroke endpoint and the protrusion ensures that the opening and retraction of the chuck 23 reach a definite and consistent position each time, improving the standardization and success rate of the operation.

[0048] In some embodiments, a limiting member 40 is fixedly provided on the inner side of each sliding arm 22. The limiting member 40 slides between the top wall of the mounting cavity 1212 and the first protrusion 14. When the limiting member 40 abuts against the top wall of the mounting cavity 1212 (i.e., the end near the pressing ring 21), it corresponds to the second stroke endpoint 222 abutting against the second protrusion 15, defining the contraction limit. When the limiting member 40 abuts against the upper edge of the first protrusion 14, it corresponds to the first stroke endpoint 221 abutting against the first protrusion 14, defining the opening limit. This design utilizes the limiting member 40 as the main stopping component, and its contact area can be designed to be larger than the stroke endpoint, thereby being able to withstand greater impact force, disperse stress, and improve the durability and lifespan of the tool.

[0049] To optimize the smoothness of the sliding and contacting processes, the first protrusion 14 includes a first arcuate surface 141 facing downward, a first inclined surface 142 located above the first arcuate surface 141, and a contact surface 143 located at the top of the first inclined surface 142. The inclination direction of the first inclined surface 142 is consistent with the inclination direction of the sliding arm 22, and the inclination angle of the first inclined surface 142 is greater than the inclination angle of the sliding arm 22. The contact surface 143 is used to contact the limiting member 40. When the sliding arm 22 moves outward, it does not contact the first inclined surface 142 to avoid friction affecting the smoothness of tool operation. When the limiting member 40 moves to its lowest point and contacts the contact surface 143, the sliding arm 22 moves to the end of its stroke.

[0050] In some embodiments, to improve the overall strength and reliability of the second structural component 20, it is designed as a single piece, meaning that the pressing ring 21, the two sliding arms 22, and the two jaws 23 are machined from a single piece of material without any welding, screwing, or riveting points. This single-piece structure eliminates the risk of stress concentration and fatigue fracture at the joints, allowing the tool to maintain structural stability even under repeated stress, significantly improving its durability and service life. Preferably, the second structural component 20 is a sheet metal part.

[0051] In a preferred embodiment, in order to fully protect the surface of the display module 100 during disassembly and prevent scratches or indentations caused by hard contact, an elastic buffer layer 16 can be provided on the working surface of the contact portion 13 of the first structural member 10. The elastic buffer layer 16 can be made of soft materials such as rubber, silicone, or polyurethane foam, and has a certain thickness and elasticity.

[0052] The present invention also provides a method for using a display module disassembly tool, comprising the following steps:

[0053] First, before disassembly, the display module 100 needs to be pre-processed; specifically, the fasteners 104 on both sides of the display module 100 are removed, and the structure of the upper part 102 and the lower part 103 of the display module is loosened.

[0054] Next, the operator holds the disassembly tool of the present invention with one hand. A typical way of holding it is to hook the fingers on the hand-held part 11 of the first structural member 10, and press the palm against the pressing part 211 of the second structural member 20. Apply external force to make the hand-held part 11 and the pressing part 211 move relative to each other. During this process, the sliding arm 22 is driven to slide outward, compressing the elastic reset member 30 until the limiting member 40 abuts against the top wall of the mounting groove 121, and the two claws 23 open to the maximum distance.

[0055] Keeping the claws 23 open, align the open claws 23 with the slots 101 of the upper part 102 of the display module, release the external force on the first structural member 10 and the second structural member 20. Under the elastic reset action of the elastic reset member 30, the two claws 23 retract and engage in the slots 101. At the same time, due to the presence of the contact part 13, the disassembly tool can be stably placed against the surface of the display module 100.

[0056] Finally, after confirming that the claw 23 is securely engaged, the operator only needs to lift the second structural component 20 upwards to separate the upper part 102 of the display module from the lower part 103 of the display module. The entire process can be completed with one hand, with smooth movements, without the need to switch tools or postures between opening and engaging steps, thus improving the efficiency of maintenance or replacement work.

[0057] It should be noted that, since the part in contact with the upper surface of the display module 100 is an elastic buffer pad 16, and the disassembly tool is squeezed between the upper surface of the display module 100, a downward squeezing force is generated. At the same time, since the claw 23 is engaged in the slot 101 of the display module 100, it generates an upward force on the upper part 102 of the display module. The two forces are opposite in direction, which can prevent the upper part 102 of the display module from shaking and make it easier to disassemble the upper part 102 of the display module.

[0058] The display module disassembly tool provided by this invention has a wide range of applications. Its primary application is in the installation, maintenance, and repair of large LED video walls. In such applications, the video wall is composed of dozens, hundreds, or even thousands of independent display modules. When a module malfunctions, it needs to be removed from the wall for replacement. This tool allows technicians to quickly and safely replace individual modules without affecting adjacent modules or disassembling a large area of ​​the structure, improving maintenance efficiency and reducing downtime for the display screen.

[0059] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the nature and scope of the present invention. Various modifications made to the above embodiments by those skilled in the art after reading this specification are all within the scope of protection of the present invention.
