Description

Technical Field

[0001] The utility model relates to the technical field of LED display devices, in particular to an LED circuit board packaging structure. Background Art

[0002] For an LED circuit board packaging structure, heat is generated when the LED chip works. A good heat dissipation design can extend the life and stability of the LED. The design of the LED circuit board needs to consider factors such as the layout of the LEDs, circuit connection, drive circuit, etc. The optical design of the LED affects its optical characteristics such as beam angle, brightness, and color temperature, and is designed through optical elements such as lenses and reflectors to meet the optical requirements of different applications.

[0003] The existing patent (publication number: CN217655880U) proposes a Micro-LED packaging structure, which includes a circuit board, a Micro-LED chip electrically connected to the circuit board, and a light-transmitting cover plate encapsulated on the Micro-LED chip. A heat dissipation member is provided on the circuit board, and the Micro-LED chip is disposed on the heat dissipation member.

[0004] The Micro-LED packaging structure of the utility model can quickly, timely and effectively dissipate the heat generated by the Micro-LED chip, solves the heat dissipation problem of the Micro-LED chip, avoids the influence of non-uniform distribution of thermal stress and heat accumulation on the Micro-LED chip, improves the light-emitting efficiency of the Micro-LED chip, and extends the service life of the Micro-LED chip.

[0005] However, in actual use, there are still the following deficiencies. For example, the existing LED circuit board packaging structure cannot form a vacuum environment inside, which affects the sealing effect of the packaging structure. Since a vacuum environment can effectively reduce the presence of gas and moisture and avoid oxidation or corrosion of the LED circuit board, the inability to form a vacuum environment will increase the chance of contact between these harmful factors and the circuit board, thereby accelerating the aging process of the circuit and shortening the service life of the product. A vacuum environment helps to reduce thermal resistance and improve heat conduction efficiency. Therefore, the utility model proposes an LED circuit board packaging structure to solve the above problems. Summary of the Utility Model

[0014] As a preferred embodiment, a fixing assembly is arranged on the box body, the fixing assembly includes a limiting groove, the limiting groove is opened on the box body, and a second telescopic rod is fixed on one side of the box body close to the limiting groove.

[0020] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0021] In the present utility model, an operator places the LED circuit board body in the box body, clamps and fixes the LED circuit board body in the box body through the fixing component, closes the top cover to the box body, and through the cooperation of the clamping block and the clamping groove, the top cover can be limited.

[0031] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] As Figure 1 - Figure 4 shown, this embodiment provides a technical solution: an LED circuit board packaging structure, including an LED circuit board body 1, an upper cover assembly 2 is arranged on the LED circuit board body 1, and a packaging assembly 3 is arranged at the bottom of the LED circuit board body 1;

[0033] As Figure 1 - Figure 2 shown, the upper cover assembly 2 includes a top cover 21, a rubber pad 22 is fixed on the top cover 21, and a clamping block 23 is fixed on the rubber pad 22;

[0034] As Figure 1 and Figure 3 shown, the packaging assembly 3 includes a box body 31, a card slot 32 is opened on the box body 31, a sliding slot 33 is opened on the box body 31, a one-way valve 34 is fixed on the box body 31, a first telescopic rod 35 is fixed on the box body 31, a first telescopic spring 36 is arranged on the first telescopic rod 35, and a limiting block 37 is fixed on the first telescopic rod 35. In the manufacturing process of high-precision electronic devices, the packaging link of the led circuit board body 1 is particularly crucial. Through the combination of the box body 31 structure and the top cover 21, the efficient protection and sealing of the led circuit board body 1 are realized. The operator first places the led circuit board body 1 in the box body 31 and firmly clamps it with the fixing component 4 to ensure its stability in the subsequent process. Subsequently, the top cover 21 is carefully covered on the box body 31, and the limiting effect is realized through the precise cooperation of the clamping block 23 and the card slot 32 to prevent the accidental movement of the top cover 21. In order to further enhance the sealing effect, the air in the box body 31 is pumped out through the one-way valve 34 to form a vacuum environment, thereby greatly reducing the gases and moisture that may cause circuit board oxidation or corrosion. At the same time, the ingenious cooperation of the first telescopic rod 35, the first telescopic spring 36 and the limiting block 37 provides a buffering effect for the top cover 21, effectively preventing potential damage to the led circuit board body 1 caused by excessive pressure or impact, thus solving the technical problem of forming a vacuum environment in the packaging structure to enhance the sealing effect.

[0035] In the above solution, there is also a problem that when the LED circuit board body 1 is placed in the box body 31, it cannot meet the requirement of fixing the LED circuit board body 1. AsFigure 1 - Figure 2 As shown in the figure: A honeycomb panel 24 is fixed on the top cover 21. The clamping block 23 is slidably connected in the clamping groove 32, and the rubber pad 22 is slidably connected in the sliding groove 33. Since the honeycomb panel 24 is fixed on the top cover 21 and the honeycomb panel 24 has a honeycomb structure, its construction method makes it have high strength and stiffness. Since the clamping block 23 is slidably connected in the clamping groove 32, it can limit the movement of the top cover 21. Since the rubber pad 22 is slidably connected in the sliding groove 33, the rubber pad 22 can seal between the top cover 21 and the box body 31;

[0036] Such as Figure 1 and Figure 3 As shown in the figure, one end of the first telescopic rod 35 is fixed on the box body 31, and the other end of the first telescopic rod 35 is fixedly connected to the limiting block 37. Since one end of the first telescopic rod 35 is fixedly connected to the box body 31 and the other end of the first telescopic rod 35 is fixedly connected to the limiting block 37, the first telescopic rod 35 can provide an elastic force to the limiting block 37, so that the limiting block 37 can buffer the top cover 21;

[0037] Such as Figure 1 and Figure 4 As shown in the figure, a fixing component 4 is arranged on the box body 31. The fixing component 4 includes a limiting groove 41 which is opened on the box body 31. A second telescopic rod 42 is fixed on one side of the box body 31 close to the limiting groove 41. The operator pulls the clamping plate 44 and places the LED circuit board body between the fixing components 4 on the box body 31. Through the cooperation of the second telescopic rod 42 and the second telescopic spring 43, the second telescopic spring 43 is arranged on the second telescopic rod 42, and a clamping plate 44 is fixed on the second telescopic rod 42. The second telescopic spring 43 can provide an elastic force to the clamping plate 44, so that the clamping plate 44 can clamp and fix the LED circuit board body on the box body 31. One end of the second telescopic spring 43 is fixedly connected to the box body 31, and the other end of the second telescopic spring 43 is fixedly connected to the clamping plate 44. Since one end of the second telescopic spring 43 is fixedly connected to the box body 31 and the other end of the second telescopic spring 43 is fixedly connected to the clamping plate 44, the second telescopic spring 43 can provide an elastic force to the clamping plate 44, so that the clamping plate 44 can clamp and fix the LED circuit board body on the box body 31.

[0038] Working principle:

[0039] Such as Figure 1 - Figure 4As shown, first, the operator pulls the clamping plate 44 and places the LED circuit board body between the fixing components 4 on the box body 31. Through the cooperation of the second telescopic rod 42 and the second telescopic spring 43, the second telescopic spring 43 can provide an elastic force to the clamping plate 44, enabling the clamping plate 44 to clamp and fix the LED circuit board body on the box body 31 to ensure its stability in the subsequent process. Subsequently, the top cover 21 is carefully closed onto the box body 31, and the limiting effect is achieved through the precise cooperation of the clamping block 23 and the card slot 32 to prevent accidental movement of the top cover 21. To further enhance the sealing effect, the air in the box body 31 is pumped out through the one-way valve 34 to form a vacuum environment, thereby greatly reducing the gases and moisture that may cause oxidation or corrosion of the circuit board. At the same time, the ingenious cooperation of the first telescopic rod 35, the first telescopic spring 36, and the limiting block 37 provides a buffering effect for the top cover 21, effectively preventing potential damage to the LED circuit board body 1 caused by excessive pressure or impact.

[0040] The above are only the preferred embodiments of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
