Technical Field

[0001] This utility model relates to the field of LED display device processing and manufacturing, and more specifically, to an assembly fixture for an LED display cabinet. Background Technology

[0002] In related technologies, the frame structure is an important component of LED display cabinets, serving to support multiple LED display modules and control boxes.

[0003] The market is increasingly demanding lighter and more advanced products, leading to the development of carbon frame structures. Specifically, a carbon frame typically includes expanding foam, inserts mounted on the foam, and carbon cloth wrapped around the foam and inserts. Multiple expanding foam strips are joined to form the basic framework of the carbon frame, while the inserts and carbon cloth enhance its structural strength.

[0004] By incorporating magnetic components on the carbon frame, LED display modules can be magnetically attached and fixed to it. However, due to the difficulty in machining high-precision receiving cavities into the foam and carbon cloth layers, it is challenging to ensure the positional accuracy of the magnetic components on the carbon frame. This results in poor flatness of the multiple LED display modules mounted on the carbon frame, affecting the display effect. Utility Model Content

The assembly fixture for an LED display cabinet includes: a support frame for supporting the carbon frame and having a mounting surface facing the carbon frame; and multiple magnetic coupling components disposed on the mounting surface and used to magnetically engage with the multiple magnetic components one by one, so that the multiple magnetic components are arranged flush.

[0007] Furthermore, multiple mounting grooves are provided on the mounting surface, and magnetic mating parts are set in the mounting grooves, with the bottom walls of the multiple mounting grooves being flush.

[0008] Furthermore, the bottom wall of the mounting groove is a machined surface.

[0009] Furthermore, the depth D of the mounting groove is greater than the thickness T of the magnetic mating component, so that the magnetic component can extend into the mounting groove and fit snugly against the magnetic mating component.

[0010] Furthermore, the assembly fixture for the LED display cabinet also includes fasteners, which pass through the support frame and the magnetic coupling to fix the magnetic coupling to the support frame.

[0011] Furthermore, the magnetic attraction component is an electromagnet.

[0012] Furthermore, the assembly fixture for the LED display cabinet also includes a fixing component disposed on the support frame, which is used to fix the carbon frame to the support frame.

It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0022] like Figure 1 , Figure 6 and Figure 7 As shown, this application provides an assembly fixture for an LED display cabinet. An embodiment of the assembly fixture for the LED display cabinet of this application is used to install multiple magnetic components 1 within a receiving cavity 201 of a carbon frame 2. The assembly fixture for the LED display cabinet includes a support frame 10 and multiple magnetic coupling components 20. The support frame 10 supports the carbon frame 2 and has a mounting surface 11 facing the carbon frame 2; the multiple magnetic coupling components 20 are disposed on the mounting surface 11 and are used to magnetically engage with the multiple magnetic components 1 in a one-to-one correspondence, so that the multiple magnetic components 1 are flush.

[0023] By applying the technical solution of this embodiment, the magnetic locating component 20 of the assembly fixture for the LED display cabinet is used to position and level the magnetic locating component 1, ensuring that multiple magnetic locating components 1 are aligned. Then, the carbon frame 2 is placed on the support frame 10, so that the multiple receiving cavities 201 on the carbon frame 2 correspond one-to-one with the multiple magnetic locating components 1 fixed on the support frame 10, thus achieving a fixed connection between the magnetic locating component 1 and the carbon frame 2. This effectively ensures that the multiple magnetic locating components 1 are aligned with the surface of the LED display module, thereby improving the flatness of the surface of the multiple LED display modules mounted on the carbon frame 2 via the magnetic locating components 1 and enhancing the display effect. Therefore, the technical solution of this embodiment can effectively solve the problem of poor flatness of multiple LED display modules affecting the display effect in related technologies.

[0024] Specifically, in this embodiment, after the magnetic accommodating component 20 is positioned and leveled to the magnetic accommodating component 1, glue is poured into the receiving cavity 201, and then the carbon frame 2 is connected to the support frame 10 to realize the connection between the multiple receiving cavities 201 on the carbon frame 2 and the multiple magnetic accommodating components 1. After the glue is cured, the magnetic accommodating component 1 and the carbon frame 2 can be fixed.

[0025] In this embodiment, a plurality of mounting grooves 12 are provided on the mounting surface 11, and magnetic coupling parts 20 are disposed in the mounting grooves 12. The bottom walls of the plurality of mounting grooves 12 are flush. By making the bottom walls of the plurality of mounting grooves 12 flush, the surfaces of the plurality of magnetic coupling parts 20 that are away from the bottom walls of the mounting grooves 12 are also flush, thereby achieving the positioning and leveling of the plurality of magnetic parts 1 adsorbed on the magnetic coupling parts 20.

[0026] In this embodiment, the bottom wall of the mounting groove 12 is a machined surface. Machining the bottom wall of the mounting groove 12 ensures the surface accuracy of the bottom wall.

[0027] like Figure 6 and Figure 7 As shown, the depth D of the mounting groove 12 is greater than the thickness T of the magnetic mating part 20, so that the magnetic part 1 can extend into the mounting groove 12 and fit snugly against the magnetic mating part 20. By making the depth D of the mounting groove 12 greater than the thickness T of the magnetic mating part 20, the magnetic part 1 can partially extend into the mounting groove 12. The mounting groove 12 fixes the position of the magnetic part 1, so that when the carbon frame 2 aligns with the support frame 10, the magnetic part 1 can correspondingly extend into the receiving cavity 201 on the carbon frame 2. This avoids the situation where the magnetic part 1 is located outside the receiving cavity 201, which would prevent the carbon frame 2 from smoothly aligning with the support frame 10, thus ensuring the smoothness of the assembly process.

[0028] like Figure 1 , Figure 2 and Figure 7 As shown, the assembly fixture for the LED display cabinet also includes fasteners 30, which pass through the support frame 10 and the magnetic accommodating component 20 to fix the magnetic accommodating component 20 onto the support frame 10. By fixing the magnetic accommodating component 20 onto the carbon frame 2 with fasteners 30, the positional accuracy of the magnetic accommodating component 20 on the support frame 10 can be effectively guaranteed, thereby ensuring the positional accuracy and surface flatness of the multiple magnetic components 1.

[0029] Specifically, in this embodiment, the fastener 30 is a connecting screw, the support frame 10 is provided with a connecting hole communicating with the receiving cavity 201, the magnetic coupling part 20 is provided with a threaded hole on the side of the groove bottom wall near the mounting groove 12, and the connecting screw passes through the connecting hole and the threaded hole and is threadedly engaged with the threaded hole.

[0030] In this embodiment, the magnetic attraction component 20 is an electromagnet. When the electromagnet is energized, it becomes magnetic and can stably attract the magnetic attraction component 1. After the alignment of the magnetic attraction component 1 and the carbon frame 2 is completed, the power supply to the electromagnet is cut off, causing the electromagnet to be demagnetized, which facilitates the separation of the carbon frame 2 from the assembly fixture of the LED display cabinet.

[0031] In this embodiment, the magnetic suction component 1 is a magnet, and the magnetic attraction component 20 is an electromagnet. Of course, in embodiments not shown in the figures, the magnetic suction component can be a magnet, and the magnetic attraction component can also be a magnet. In this case, after fixing the magnetic suction component to the carbon frame, a certain external force needs to be applied to the carbon frame to separate it from the assembly fixture of the LED display cabinet. Alternatively, one of the magnetic suction component and the magnetic attraction component can be a magnet, and the other can be a magnetic material. In this case, after fixing the magnetic suction component to the carbon frame, a certain external force also needs to be applied to the carbon frame to separate it from the assembly fixture of the LED display cabinet.

[0032] like Figures 1 to 5 As shown, the assembly fixture for the LED display cabinet also includes a fixing component 40 disposed on the support frame 10. The fixing component 40 is used to fix the carbon frame 2 to the support frame 10. By fixing the carbon frame 2 to the support frame 10 through the fixing component 40 and fixing the magnetic component 1 to the support frame 10 through the magnetic coupling component 20, the relative positional relationship between the carbon frame 2 and the magnetic component 1 can be effectively guaranteed.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, the support frame 10 includes a main frame 13 and a connecting plate 14 disposed on the side of the main frame 13. The connecting plate 14 is set at an angle to the main frame 13. The fixing component 40 is disposed on the connecting plate 14, and the mounting surface 11 is formed on the main frame 13. The connecting plate 14 extends to the side of the carbon frame 2, thereby fixing the carbon frame 2 from the side.

[0034] like Figures 1 to 5 As shown, the connecting plate 14 includes a first plate 141 and a second plate 142. The first plate 141 and the second plate 142 are respectively connected to two opposite sides of the main frame 13. The fixing assembly 40 includes a fixing locking plate assembly 41 disposed on the first plate 141 and a fixing locking pin assembly 42 disposed on the second plate 142. The fixing locking plate assembly 41 can lock and engage with the quick-locking pin on the carbon frame 2, and the fixing locking pin assembly 42 can lock and engage with the quick-locking plate on the carbon frame 2. Since the carbon frame 2 is provided with a quick-locking plate and a quick-locking pin for assembling with adjacent carbon frames 2, directly setting the fixing locking plate assembly 41 on the first plate 141 that can lock and engage with the quick-locking pin on the carbon frame 2, and setting the fixing locking pin assembly 42 on the second plate 142 that can lock and engage with the quick-locking plate on the carbon frame 2, can make full use of the original structure of the carbon frame 2 to achieve a fixed connection between the carbon frame 2 and the support frame 10, which has the advantages of simple structure and easy operation.

[0035] like Figure 4 and Figure 5As shown, the fixed locking pin assembly 42 has the same quick-locking pin structure as the carbon frame 2. The fixed locking pin assembly 42 includes a second fixing plate 421 and a locking pin 422. The locking pin 422 is mounted on the second plate 142 via the second fixing plate 421 and extends along... Figure 5 It is movably set in the vertical direction. The end of the locking pin 422 is provided with a locking ring groove.

[0036] like Figure 2 and Figure 3 As shown, the fixed locking plate assembly 41 has the same structure as the quick-locking plate on the carbon frame 2. The fixed locking plate assembly 41 includes a first fixed plate 411 and a locking plate 412 movably disposed between the first fixed plate 411 and the first plate body 141. The locking plate 412 has a first hole segment and a second hole segment that are connected to each other. The diameter of the first hole segment is larger than the diameter of the second hole segment. The diameter of the first hole segment is larger than the diameter of the head of the locking pin 422. The diameter of the second hole segment is smaller than the diameter of the head of the locking pin 422 but larger than the diameter of the bottom wall of the locking ring groove.

[0037] In this embodiment, the support frame 10 is made of metal. Using metal to make the support frame 10 can effectively ensure the surface accuracy of the bottom wall of the mounting groove 12, thereby ensuring the positioning and leveling effect of the magnetic suction component 1.

[0038] Preferably, the support frame 10 is made of aluminum alloy. That is, the support frame 10 is an aluminum alloy frame, which is formed by machining.

[0039] The assembly process of the LED display cabinet assembly fixture for assembling the carbon frame 2 and the magnetic component 1 is as follows: First, multiple magnetic components 1 are attracted and fixed onto the support frame 10 by magnetic attachment 20; Structural adhesive is applied inside the receiving cavity 201 of the carbon frame 2; The support frame 10 and the carbon frame 2 are fixedly connected by the fixing component 40, and the carbon frame 2 is bonded to the magnetic suction component 1. After standing for 12 hours and the structural adhesive has cured, the assembly fixture of the LED display cabinet can be removed to obtain a carbon frame structure with a high-precision positioning plane, which meets the accuracy requirements for the installation and positioning of the front maintenance magnetic LED display module.

[0040] It should be noted that the magnetic coupling component 20 is an electromagnet, which can be de-energized when the carbon frame 2 is fixed on the support frame 10.

[0041] In the description of this utility model, it should be understood that "multiple" means two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0042] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0043] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
